Description

[Detailed Description of the Invention] The present invention is applied to a printing apparatus for ceramic ICs in which lead wires b are taken out from both sides of a ceramic piece a on which an IC circuit is molded, as shown in FIGS. 3 and 4, for example. Related.

Ceramic is suitable as a material for this type of electrical parts due to its electrical insulation properties and no generation of static electricity, but on the other hand, it is brittle and lacks strength.
When printing symbols, etc. on the surface, it often gets damaged due to pressure from the printing wheel, so in order to ensure safe handling especially until it is manufactured into a product, reinforcing pieces c are fitted to both ends of the ceramic piece a as shown in the figure. When a ceramic piece is placed on a flat surface, protrusions are formed on the lower surface of both ends, creating a bridge-like shape in the middle. Therefore, when printing on that surface, when printing pressure is applied to the top surface, the ceramic piece a The rate of damage is high due to vulnerability.

The present invention provides an apparatus that can safely print on ceramic ICs that are easily damaged by pressure, as described above, and will be described with reference to the illustrated embodiments.

In the drawing, reference numeral 1 denotes a printing plate wheel, and a track 2 for providing and guiding a ceramic IC to be printed is provided opposite to this. In the illustrated example, the track 2 consists of a track piece with a convex cross section, which is provided at an angle with respect to the printing wheel 1,
A large number of ceramic ICs (hereinafter referred to as the printing material 10) are made to slide down the slope automatically by extending lead wires b on both sides of the top surface, and one of the ceramic ICs from the tip is placed on the printing wheel 1. In other words, the container frame 40 provided on the lower surface of the track 2 is provided with a lever piece 41 with an intermediate pivot 42, and the front part of the pins 43 and 44 attached to both ends of the lever piece 41 is provided. The pin 44 is made to protrude in front of the frontmost one of the 10 groups of printing materials on the track 2 to prevent the 10 groups of printing materials from sliding down, and the rear pin 44 is opposed to the lower surface of the second printing material 10. A rack 47 connected to the piston rod of an air cylinder 46 is engaged with a pinion 45 attached to the shaft support 42 of the lever piece 41, and the air cylinder 26 is operated to swing the lever piece 41 and move the rear pin 44 upward. Then, the second printing material 10 is pushed up using spring pressure, and it is pressed from below by the receiving track 2' that prevents the printing material 10 from floating upward along the upper surface of the track 2. The sliding of the printed materials below the second most damaged printed material is restrained, and in synchronization with this, the front pin 43 is moved down to release the restraint on the foremost printed material 10 and move it forward. Then, when the lever piece 41 swings again and the front and rear pins 43, 44 alternate vertically, the second and lower printing materials 10 are received by the protruding front pin 43. , Thus, the front and rear pins 43 and 44 alternately move up and down, so that the frontmost printing material 1
0 slides forward along track 2, printing wheel 1
A stopper 9 whose tip is projected above the track 2 by a spring force is provided at the standby position to correctly support the printing medium 10 supplied from the feeding mechanism at the standby position. I tried to let him do it. Note that the mechanism for feeding the printing medium 10 toward the one-by-one standby position by alternately moving the two pins 43 and 44 up and down is not limited to the above mechanism, and any other suitable mechanism may be employed.

The movable frame 3 is moved parallel to the track 2 along the guide rod 12 stretched between the fixed machine frames 11 and 11 on the lower surface of the printing material 10 to be stopped at a standby position with respect to the plate wheel 1. An endless chain 13 is installed on one side of the chain 12 and is driven parallel to the track 2 at the same speed as the rotation linear speed of the printing wheel 1, and is taken out from the electromagnetic brake device 14 attached to the moving frame 3. The sprocket 15 fixed to the shaft is attached to the chain 1.
4 was engaged. The electromagnetic brake device 14 operates a brake mechanism in accordance with an electric signal to stop the sprocket 1.
The shaft 5 is restrained from rotating, and the restraint is released to allow the sprocket 15 to rotate freely. Therefore, when the brake mechanism is inoperative, the sprocket 15 engages with the chain 13 and rotates freely, but if a signal is given to the electromagnetic device 14 and the brake mechanism is activated, disabling the rotation of the sprocket 15, the chain 13 moves the sprocket 15 in its driving direction, that is, to the left in FIG. When the movable frame 3 moves a predetermined distance and presses the limit switch 16, the brake mechanism of the electromagnetic device 14 is released, and at the same time, the piston rod 18 is operated to protrude by driving the air cylinder 17 attached to the front fixed machine frame 11. The moving frame 3 is returned to its original position and the piston rod 18 is moved back. In this way, the movable frame 3 is moved forward from the stop position by activating the electromagnetic brake device 14 under the printing material 10 in the standby position at a suitable time, that is, by an electric signal transmitted as the plate wheel 1 rotates. After moving, it automatically moves back to the original position after moving a predetermined amount.
The forward movement speed is regulated by the driving speed of the chain 13, which is made to match the rotational linear speed of the plate wheel 1 as described above, and thus the rotation of the plate wheel 1 to the printing material 10, which will be described later. Smooth printing operation. A swinging piece 5 with one end supported by a shaft 6 is provided on the upper part of the moving frame 3, and this is connected to a piston rod 20 of an air cylinder 19 tied to the lower part of the moving frame 3, so that it can be swung up and down by the operation of the cylinder device. The synchronous operation is performed simultaneously with an electric signal to the electromagnetic brake device 14 accompanying the rotation of the plate wheel 1.
The cylinder 19 is actuated to move the cylinder upward, and the swinging piece 5 is moved downward when the electromagnetic device 14 is released by the limit switch 16 and when the moving frame 3 is moved back and forth by the cylinder 17.

The rocking piece 5 is provided with a pressing piece 7 which is pressed against the underside of the print medium 10 in the standby position when the rocking piece 5 moves upward, and a pushing piece 8 which protrudes from the rear of the print medium 10 in the standby position. When the rocking piece 5 moves downward, these pieces move downward from the standby position of the print medium 10 so as not to interfere with the operation of feeding a new print medium 10 to the standby position. When the rocking piece 5 moves upward, the track 2
The upper and lower ends of the rods are projected upward through slots 4 formed in the rods.

It is preferable that the mounting position of the pressing piece 7 and the pushing piece 8 relative to the swinging piece 5 can be adjusted in accordance with variations in the length of the printing medium 10.

In the above configuration, after the printing material 10 is supported by the stopper 9 at the standby position with respect to the printing wheel 1 and fed into a fixed position, an electric signal is sent to the electromagnetic brake device 14 in synchronization with the rotation of the printing wheel 1. When the rotation of the free-rotating sprocket 15 is controlled, the moving frame 3 starts to move at the same speed and in the same direction as the plate wheel 1 along with the chain 13, but at the same time, a signal to the cylinder 19 causes the moving frame 3 to start moving in the same direction as the plate wheel 1. The movable piece 5 is moved upward and the pressing piece 7 presses and holds the lower surface of the printing material 10, and the pushing piece 8 protrudes to push the printing material 10 together with the moving frame 3.
are removed in the same direction while resisting the spring against the stopper 9, and printing is performed on the upper surface of the plate by the plate wheel 1. In that case, the ceramic piece a of the printing medium 10
Since the lower surface is held by the pressing piece 7, it will not be damaged by pressure during printing.

In this way, when the moving frame 3 moves a predetermined distance, that is, the area where the printing operation ends, the switch 16 is pushed, so the sprocket 15 that engages with the chain 13 rotates freely, and is further pressed by the downward movement of the swinging piece 5 by the cylinder 19. The piece 7 and the pushing piece 8 retreat downward, and the printed material 10 that has finished printing slides down along the track 2 and is conveyed to the next process position, and the moving frame 3 is moved back and forth to its original position by the cylinder 17. The above-mentioned operations are repeated to print on each printing medium 10 that is sent to the standby position and then send it out.

According to the present invention, a moving frame 3 is provided below the printing material 10 in a standby position with respect to the printing wheel 1, and the moving frame 3 is provided to perform a predetermined amount of reciprocating motion in synchronization with the printing wheel 1. A pressing piece 7 that presses against the lower surface of the printing material 10 in a standby position and a pushing piece 8 that pushes the printing material 10 at the same speed and in the same direction as the plate wheel 1 are provided to suppress the lower surface of the printing material 10 during printing. Print ring 1 while holding
Since printing is carried out by applying pressure to the ceramic material, printing can be carried out extremely safely and smoothly without causing damage to the printing material 10 made of ceramic material due to the pressure applied by printing. This has the effect of eliminating yield problems caused by damage and improving printing efficiency.
