Description

Detailed Description of the Invention (Industrial Application Field) When a robot is used to perform production processing such as cutting or bending the legs of a component assembled on a printed circuit board, the present invention can be applied to The present invention relates to a board positioning device used when positioning a printed circuit board within the operating range of a robot.

(Prior Art) Conventionally, as an example of the above-mentioned substrate positioning device,
There is a type of robot in which a stopper for stopping a printed circuit board (hereinafter referred to as "board") is provided in a printed circuit board transfer device located near the front end of the robot's operating range. In this device, when the substrate reaches the position of the stopper, the stopper comes into contact with the substrate and stops the substrate, thereby placing the substrate within the operating range of the robot. Then, by operating the robot in this stopped state, it performs production processing on the board, such as cutting or bending the legs of electronic components mounted on the board.

(Issues to be Solved by the Invention) However, when attempting to apply a substrate having a length to be processed in the transport direction that is longer than the operating range of the robot to the above-mentioned conventional substrate positioning device, There is a problem in that the rear part of the processing target part is removed from the operating range and is left unprocessed, which limits the substrates that can be applied to the substrate positioning apparatus.

The present invention was made to solve the above-mentioned problems, and it is an object of the present invention to provide a highly versatile substrate positioning device that can be used for a substrate having a part to be processed whose length is longer than the operating range of a robot. With the goal.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a robot that performs production processing on printed circuit boards.

The operating range is located in the middle of the transport path of the printed circuit board transport device, and the printed circuit board is stopped at a position where the front end of the processed portion of the printed circuit board substantially coincides with the front end of the operating range. The present invention is characterized in that one stopper is provided on the printed circuit board transfer device, and a second stopper for stopping the printed circuit board is provided on the portion of the transfer device located in front of the first stopper.

(Function) Since the present invention is configured as described above, by stopping the printed circuit board at the first and second stoppers, the portion of the processed portion that falls within the operating range of the robot is changed. As a result, even if a substrate with a long branching processing section is applied, production processing can be performed on the entire range of the processing target section.

, 7b are arranged parallel to each other with a certain distance between them. The conveyor bases 7a and 7b are provided with conveyors 8a and 8b (hereinafter collectively referred to as conveyors 8) spaced apart from each other by a certain distance on opposite sides thereof. Conveyor 8 is board 1.2

Indicated by

A robot 10 is provided below the conveyor 8 in the middle of the conveyance path 9. The robot 10 has a cutting flange 11.

The cut/flanch head 11 is capable of operating within a range corresponding to the processed portion lc of the substrate 1 (hereinafter referred to as operating range B).
Production processes such as cutting and bending the legs (not shown) of electronic components such as resistors that are mounted on the holder 2 are performed.

A transport base 7a located near the front end Bf of the operating range B
A first stopper 12 is provided.

The first stopper 12 operates in synchronization with the conveyor 8, and when the substrates 1.2 are conveyed, it protrudes across the conveyance path 9 and comes into contact with it to stop each substrate.

Also, when looking at the distance 12 1 += from the first stopper 12,

stop.

A reference bin 14b on the rear side is provided on the transport base 7b at a distance extending rearward from the front end Bf of the operating range B. Also, a distance sentence is written backward from the front reference bin 14b.
A front driven pin 15f is provided on the conveyance base 7b at a distant portion. Rear reference bin 14b, front driven pin 1
Each of 5f is approximately L-shaped, and its tip end is connected to the substrate l.

The thickness is such that it can be inserted into each of the positioning holes 4.6. Further, the reference bin 14b on the rear side and the driven pin ISf on the front side are configured to simultaneously rotate along the vertical plane when the first stopper 12 stops the substrate l.

Further, a rear driven bin 15b is provided on the transport base 7b at a distance is distance backward from the rear reference bin 14b. Further, a front reference bin 14f is provided on the transport base 7b at a distance from the front driven pins 1, 5f forward. The front reference bin 14f and the rear driven pin 15b have the same structure as the rear reference bin 14b and the front driven pin 15f. In this case, when the first stopper 12 stops the substrate 2, the rear driven pin 15b and the rear reference bin 11

The operation of the positioning device configured as above will be explained.

First, when the substrate 1 is transported by the conveyor 8 and reaches the position of the first stopper 12, the first stopper 12 stops the substrate 1. Then, the rear reference bin 14b and the front driven bin 15f are rotated and inserted into the positioning holes 4.4 of the board 1 at the relevant position, and the board 1 is positioned in the operating range B. In this state, the robot 1.0 operates and performs production processing on the substrate l.

When this production process is finished, the rear ) Ji semi-upper pin 14
b, the locking by the front driven bin ISF and the first stopper 12 is released, and the substrate 1 is further conveyed in the direction of the arrow by the conveyor 8 and sent to the next process.

Further, when the substrate 2 is being transported, when the substrate 2 reaches the first stopper I2, the first stopper 12 stops the substrate 2. In response to this, the rear driven bin 15b and the rear reference bin 14b are rotated and inserted into the positioning holes 5.5 of the substrate 2 in the corresponding portions, thereby positioning the substrate 2 in the operating range B. In this state, the robot 10 operates and performs production processing on the board 2. In this processing, the part between the part 2e and the rear end 2b (hereinafter referred to as (referred to as the rear part) will be left unprocessed.

When this process is completed, the locking by the rear driven bin 15b, the rear reference bin 14b, and the first stopper 12 is released, and the substrate 2 is further conveyed by the conveyor 8 in the direction indicated by the arrow. Then, when the substrate 2 reaches the second stopper 13, the substrate 2 is stopped by the second stopper 13. Then, in response to this, the front reference bin 14f and the front driven pin ]Sf rotate to move the board 2 in the corresponding part.
into the positioning hole 5.5 to position the board 2.

In this state, the rear portion of the board 2 falls within the operating range B. Then, the robot IO performs production processing on this rear portion, and completes the production processing over the entire range of the processing target portion 2c.

In this way, not only the substrate l but also the processed portion 2c of the substrate 2
Since the production process can be carried out over the entire range of products, the number of types of substrates that can be applied is increased compared to the conventional apparatus described above.

In this embodiment, the second stopper is used as an example, but the second stopper is not necessarily limited to this, and a plurality of stoppers may be provided. By doing so, it is possible to further increase the types of applicable substrates.

(Effects of the Invention) As explained above, the present invention has the following advantages. When the substrate is stopped at each of the second stoppers, the portion of the processed portion that falls within the operating range of the mouth pot is changed, and even if a substrate with a longer processed portion is used, the portion of the processed portion that falls within the operating range of the mouth pot is changed. Now we can perform production processing over the entire range,
Furthermore, the present invention can be applied to substrates having different lengths of treated parts, and has the effect of increasing versatility.
