The invention belongs to a method or special equipment for sealing battery boxes, covers or sleeves, and specifically discloses a battery injection molding equipment.

Background technique

Lithium battery is one of the most widely used battery types at present. In our daily use of mobile phones, laptops and other digital products, the battery used is lithium battery. Lithium battery has become a One of the most heavily used batteries.

The lithium battery in the mobile phone is often replaced, so in order to improve its durability and make it able to withstand multiple plugs and unplugs, a head shell is installed at the end of the battery, and the positive and negative electrodes of the battery are installed on the head shell. The head shell is usually made of hard plastic. The head shell protects the battery body and prevents frequent plugging and unplugging from damaging the battery body. At present, during the assembly process of the head shell and the battery body, there will be a There are gaps. In the prior art, plastic is filled in the gaps by injection molding in the gaps, so that the gaps are blocked, so that the head case and the battery body are connected and fixed under the action of the plastic, and at the same time, the gap between the battery body and the head case is fixed. The gaps between the batteries are sealed to prevent the battery body from being in contact with the outside air, resulting in the loss of effective materials in the battery.

However, at present, when injecting the head shell, it is often necessary for the staff to operate manually. The battery is placed on the processing position manually and then the battery position is adjusted to ensure that the battery position is aligned with the injection molding device, and then the injection molding device is pressed on the battery by hydraulic pressure. If the battery is not aligned, the battery is prone to explosion under hydraulic pressure. If the battery is aligned, the staff needs to manually align it, and the staff's hands must be operated under the hydraulic mechanism. There is a great danger to the safety of workers.

Technical principle of the present invention and beneficial effect are:

1. In the present invention, by setting the positioning mechanism, when the driving mechanism drives the box to move downward, the left positioning plate and the right positioning plate are in contact with the conveyor belt, and then the ends of the left positioning plate and the right positioning plate that are in contact with the conveyor belt are turned upward until The left positioning plate and the right positioning plate are parallel to the upper surface of the conveyor belt. When the left positioning plate and the right positioning plate are turned upward, the battery on the conveyor belt is pushed, so that the battery is pushed to the center of the left positioning plate and the right positioning plate. Position, and when the left positioning plate and the right positioning plate are parallel to the upper surface of the conveyor belt, the battery is clamped and positioned, so that there is no need to manually adjust the battery placement position, and through the positioning of the left positioning plate and the right positioning plate, it is ensured in The battery will not be displaced during the injection molding process, ensuring the stability of the injection molding process.

2. The present invention sets the injection molding mechanism so that when the left positioning plate and the right positioning plate are reversed up to be parallel to the conveyor belt, the left positioning plate and the right positioning plate cannot continue to turn over, and with the force of the driving mechanism, the box body Continue to move downward, while the left sliding rod and the right sliding rod are kept still by the support force of the conveyor belt, which makes the relative movement between the box and the left sliding rod, and then makes the left sliding rod drive the gear to move, and the gear drives the injection piston rod to move. The piston rod drives the injection piston plate to move, so that the injection piston plate ejects the molten plastic in the injection cylinder from the injection head to achieve the injection molding effect.

3. The present invention sets the first return compression spring so that when the drive mechanism drives the box to move upward, the left sliding rod no longer touches the conveyor belt, so that the left sliding rod no longer exerts force on the gear, and the gear no longer exerts force on the injection piston rod. Therefore, under the action of the first return compression spring, the injection piston plate moves upwards, thereby reducing the pressure in the injection cylinder below the injection piston plate, and thus reducing the pressure in the feeding pipe, so that the molten plastic is under pressure. Under the action, it flows from the feed pipe into the injection molding cylinder to complete the replenishment of molten plastic.

Further, there is a separation through hole on the upper wall of the box directly above the left sliding rod. The side of the separation through hole close to the injection molding piston rod is an inclined plane for driving the left sliding rod to move away from the injection molding piston rod. The left sliding rod is far away from the injection molding cylinder. A horizontal reset mechanism is provided between one side of the cylinder and the inner wall of the box. The horizontal reset mechanism is used to provide force towards the direction of the injection molding cylinder for the left slider. reed. Through the above design, when the left sliding rod is in contact with the conveyor belt and is still, with the downward movement of the box, the upper end of the left sliding rod enters the separation through hole, and the left sliding rod moves away from the injection piston rod under the action of the inclined surface. Then the left sliding rod is no longer meshed with the gear, so that the gear is no longer limited by the left sliding rod, and the injection piston rod is not limited by the gear, so the injection piston plate is reset under the action of the first reset compression spring, and then To complete the feeding work, compared with the left sliding rod always meshing with the gear, this optimal solution completes the feeding work when the drive mechanism does not drive the box to move upwards, and the work efficiency is higher.

Further, the horizontal reset mechanism includes a first sleeve and a second sleeve, the first sleeve is coaxially provided with an annular chute, the second sleeve is slidably connected in the annular chute, the first sleeve and the second A second reset compression spring is installed in the second casing, one end of the second reset compression spring is fixedly connected to the inner wall of the box, the other end of the second reset compression spring is fixedly connected to a sliding sleeve, and the sliding sleeve is also fixedly connected to the second chute. The sliding sleeve is provided with a chute for the sliding of the left sliding rod. Through the above design, when the left sliding rod slides out of the separation through hole, under the action of the second reset compression spring, the second bushing slides out of the annular chute and pushes the sliding sleeve, so that the sliding sleeve pushes the left The sliding rod moves toward the direction close to the injection molding piston rod, so that the left sliding rod and the gear are in meshed state.

Further, a cooling mechanism is also included, and the cooling mechanism is driven by the right sliding rod. Through the above design, when there is relative movement between the right sliding rod and the box body, the cooling mechanism is driven, so that the molten plastic ejected from the injection molding head is rapidly cooled and hardened.

Through the above design, when the right sliding rod is in contact with the conveyor belt and is still, as the box moves downward, the right sliding rod pushes the first transmission piston plate to slide in the first transmission cylinder, thereby making the first transmission cylinder The internal pressure increases, because the second transmission cylinder communicates with the first transmission cylinder through the communication pipe, so the pressure increase in the first transmission cylinder is transmitted to the second transmission cylinder, so that the second transmission piston plate is limited Under the limit of the position mechanism, it slides axially along the second transmission cylinder, so that the screw rotates, and the screw drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the rotating shaft Rotating, the rotating shaft then drives the fan blades to rotate, so as to achieve the effect of blowing air on the injection head, so that the cooling and hardening speed of the molten plastic is accelerated.

The specific implementation process is as follows: start the conveyor belt 2, the hydraulic cylinder 3 and the heating wire 10, and when the hydraulic cylinder 3 drives the box body 4 to move downward, the box body 4 drives the first return extension spring 17 and the second return extension spring 18 downward together Therefore, under the pulling of the first return tension spring 17 and the second return tension spring 18, the left sliding rod 5 and the right sliding rod 7 move downward together with the box body 4, so that the lower ends of the left sliding rod 5 and the right sliding rod 7 are hinged The left positioning plate 6 and the right positioning plate 8 move downwards, so that the lower ends of the left positioning plate 6 and the right positioning plate 8 are in contact with the upper surface of the conveyor belt 2. It forms an included angle of 30 degrees, so under the action of the supporting force provided by the conveyor belt 2, the left positioning plate 6 rotates counterclockwise, and the right positioning plate 8 rotates clockwise. When the left positioning plate 6 and the right positioning plate 8 rotate to be parallel to the conveyor belt 2 When the upper end face is no longer rotated, during the rotation of the left positioning plate 6 and the right positioning plate 8, the battery 14 on the conveyor belt 2 is pushed, so that no matter whether the battery 14 is placed in a position aligned with the injection molding head 12, as long as the battery 14 is in Between the left positioning plate 6 and the right positioning plate 8, under the rotation of the left positioning plate 6 and the right positioning plate 8, the battery 14 can be pushed to the position aligned with the injection molding head 12 and the battery 14 can be clamped and positioned. It is guaranteed that the battery 14 will not be displaced during the injection molding process, and there is no need to manually adjust the position of the battery 14 .

After the left positioning plate 6 and the right positioning plate 8 rotate to be parallel to the upper end surface of the conveyor belt 2, the left sliding rod 5 and the right sliding rod 7 are against the upper end surface of the conveyor belt 2. Therefore, under the limit of the conveyor belt 2, the left sliding rod 5 and the right sliding rod 7 cannot Continue to move downward, and both the left sliding rod 5 and the right sliding rod 7 are supported by the vertical upward support force from the conveyor belt 2, and at the same time, the hydraulic cylinder 3 drives the box body 4 to continue to move downward, so that the gear 20 continues to move under the drive of the box body 4. downward movement, while the left sliding rod 5 remains stationary relative to the conveyor belt 2, thereby causing the gear 20 to rotate clockwise, the gear 20 drives the injection molding piston rod 19 to move downward, and the injection molding piston rod 19 drives the injection molding piston plate 11 to move downward, so that The molten plastic in the injection cylinder 9 below the injection piston plate 11 is sprayed from the injection hole and the injection head 12 onto the battery 14 by the pressure of the injection piston plate 11, and the battery 14 is injected;

With the continuous downward movement of the box body 4, when the box body 4 moves to the upper end of the left sliding rod 5 and enters the separation through hole 15, since the right side wall of the separation through hole 15 is an inclined plane, under the action of the inclined plane, along with the box The downward movement of the body 4 pushes the left sliding rod 5, causing the left sliding rod 5 to slide to the left, so that the left sliding rod 5 no longer meshes with the gear 20, so that the gear 20 no longer drives the injection piston rod 19 to move downward. Therefore, under the action of the first return compression spring, the injection piston plate 11 is subjected to upward elastic force to drive the injection piston rod 19 to move upward and reset. During the upward movement of the injection piston plate 11, the injection molding under the injection piston plate 11 Negative pressure is generated in the cylinder 9, and then negative pressure is generated in the feed pipe 13, so that the molten plastic enters the injection cylinder 9 from the feed pipe 13. Since the heating wire 10 is installed in the side wall of the injection cylinder 9, Under the heating of the heating wire 10, the molten plastic in the injection molding cylinder 9 is kept in a molten state to avoid its solidification.

Simultaneously, because the right sliding rod 7 is kept stationary against the conveyor belt 2 during the downward movement of the box body 4, the right sliding rod 7 pushes the first transmission piston plate 22 to move upward, and then the hydraulic oil in the first transmission cylinder 21 is affected. The pressure from the first transmission piston plate 22 moves toward the second transmission cylinder barrel 23 through the communication pipe 26, so that the second transmission piston plate 24 is subjected to the pressure from the hydraulic oil and moves downward, and the second transmission piston plate 24 During the downward movement, since the edge of the second transmission piston plate 24 has a limit groove, and the limit groove is slidably connected with the limit protrusion, so the second transmission piston plate 24 will only move in the vertical direction without rotation. , the second transmission piston plate 24 moves downward to drive the lead screw 25 to rotate, the lead screw 25 then drives the first bevel gear 27 to rotate, the first bevel gear 27 drives the second bevel gear 28 to rotate, and the second bevel gear 28 drives the rotating shaft 31 Rotating, the rotating shaft 31 further makes the fan blade 32 rotate, and the rotation of the fan blade 32 generates air flow, thereby accelerating the air flow velocity at the contact point between the injection molding head 12 and the battery 14, so that the cooling and hardening speed of the plastic is accelerated.

When the hydraulic cylinder 3 drives the casing 4 to move upward, since the first return extension spring 17 and the second return extension spring 18 are stretched during the descent of the casing 4, when the casing 4 moves upward, the first return pull spring 18 is stretched. The spring 17 and the second reset extension spring 18 are gradually restored to their original state. During the restoration process of the first reset extension spring 17 and the second reset extension spring 18, the left sliding rod 5 and the right sliding rod 7 are respectively subjected to the first reset extension spring 17 and the second return extension spring 17. Due to the downward elastic force of the two reset extension springs 18, the left sliding rod 5 and the right sliding rod 7 remain stationary before the first return extension spring 17 and the second return extension spring 18 fully return to their original state.

During the upward movement of the box body 4 while the left sliding rod 5 and the right sliding rod 7 are stationary, the first return tension spring 17 pulls the left sliding rod 5, so that the left sliding rod 5 slides out from the separation hole, so that the slope no longer faces the left sliding rod 5 generates a thrust to the left, and under the action of the second return compression spring 36, the second sleeve 35 slides out from the annular chute 34 in the first sleeve 33, and then pushes the sliding sleeve 37 to the right, so that the sliding The sleeve 37 pushes the left sliding rod 5 to move to the right, so that the left sliding rod 5 is in mesh with the gear 20 again. At the same time, the second return tension spring 18 pulls the right sliding rod 7, so that the right sliding rod 7 pulls the first transmission piston plate 22, and then the first transmission cylinder 21 moves upwards while the first transmission piston plate 22 remains stationary, so that the first transmission piston plate 22 remains still. The pressure in the transmission cylinder 21 decreases, so that the hydraulic oil in the second transmission cylinder 23 flows into the first transmission cylinder 21 through the communication pipe 26, so that the second transmission piston plate 24 moves upward, and the second transmission piston plate 24 The upward movement will drive the lead screw 25 to rotate again, and the lead screw 25 will drive the fan blade 32 to rotate again through the transmission of the second bevel gear 28, the first bevel gear 27 and the rotating shaft 31, and then cool down the injection molding head 12 again, and then accelerate The cooling and hardening rate of molten plastic.

After the first return extension spring 17 and the second return extension spring 18 are fully restored to their original state, under the pull of the first return extension spring 17 and the second return extension spring 18, the left sliding rod 5 and the right sliding rod 7 are driven to move upward, and the left sliding rod 5 And the upward movement of the right sliding rod 7 drives the left baffle and the right baffle to move upward. Since the left baffle and the right baffle are respectively hinged with the left sliding rod 5 and the right sliding rod 7, the left baffle rotates clockwise and the right baffle rotates counterclockwise. Therefore, the battery 14 is no longer positioned and clamped, and the injection molding process of the battery 14 is completed.

It should be pointed out that for those skilled in the art, under the premise of not departing from the structure of the present invention, several modifications and improvements can also be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation of the present invention.
