Description

Technical Field

[0001] The invention relates to the field of circuit board manufacturing, in particular to a board collecting device and method for an inner-layer etched board. Background Art

[0002] The inner layer etched board is a circuit board that uses the inner layer etching process. Inner layer etching refers to the processing of the inner layer copper foil of the circuit board, mainly to form a circuit connection. The copper foil that does not need to be retained is removed by etching to form a circuit connection, and finally the inner layer circuit board is formed. After the inner layer etched board is manufactured, multiple circuit boards are stacked using a board collection device and then transferred to the warehouse for storage. When collecting and stacking the inner layer etched boards, a layer of separator paper needs to be placed between the upper and lower adjacent inner layer etched boards to protect the upper and lower adjacent inner layer etched boards and prevent scratches and damage between the surfaces of the adjacent stacked inner layer etched boards.

[0003] After the existing board collecting device collects the circuit boards, each piece of separator paper needs to be manually placed between the upper and lower adjacent inner etched boards. This has the problems of low automation, time-consuming and labor-intensive, high labor costs and low stacking efficiency. In addition, after the existing board collecting device stacks each box of inner-layer etched boards, it needs to be manually transferred into the warehouse, and multiple boxes of inner-layer etched boards cannot be uniformly transferred into the warehouse. This has the problem of low work efficiency in collecting and transferring boards into the warehouse. Summary of the invention

[0045] A board collecting method for inner-layer etched boards, based on the above-mentioned board collecting device, comprises the following steps:

[0046] S1. Put the cut paper into the paper box. Each stacking box is connected to the corresponding horizontal slide rail through a buckle, and the transfer cart is pushed into the space of the sub-frame.

[0047] S2. The inner etched board manufactured in the previous process moves from the front end of the conveyor belt to the end of the conveyor belt under the action of the conveyor belt. The image collected by the visual sensor at the bottom of the first vacuum suction cup is compared with the position image of the inner etched board stored in the control system. The X-axis moving module is controlled to drive the first vacuum suction cup to move along the X-axis direction, so that the first vacuum suction cup is directly above the inner etched board. The first electric telescopic rod drives the first vacuum suction cup to move downward and sucks the inner etched board to move toward the stacking box.

[0048] S3. The image collected by the visual sensor at the bottom of the first vacuum suction cup is compared with the image of the stacking box stored in the control system. At this time, the first stacking box is located in the center of the horizontal slide rail, and the first electric telescopic rod drives the first vacuum suction cup to move downward to release the inner etched board into the first stacking box.

[0049] S4. The second electric telescopic rod drives the second vacuum suction cup to move downward and absorb the separator paper. The separator paper is rotated 180 degrees by the rotating motor and is located above the first stacking box. The second electric telescopic rod drives the second vacuum suction cup to move downward to release the separator paper onto the inner etched plate in the first stacking box.

[0050] S5. The first vacuum suction cup repeatedly completes the suction and release of multiple inner-layer etched plates, and the second vacuum suction cup repeatedly completes the suction and release of multiple sheets of separator paper until the first stacking box is full of inner-layer etched plates, and the vertical slide rail drives the stacking box on the first horizontal slide rail to move upward, and the first horizontal slide rail drives the first stacking box to move horizontally to the end of the first horizontal slide rail to make room for the second stacking box.

[0051] S6. Then the vertical slide rail drives the second stacking box on the second horizontal slide rail to move upward to a preset position, and steps S1 to S4 are repeated until the second stacking box is full of inner etched plates. The second stacking box repeats the operation of step S5 to make room for the third stacking box, and the remaining stacking boxes are repeated by analogy.

[0052] S7. After all stacking boxes are filled with inner etched boards, push the transfer cart into storage.

[0053] Before collecting the inner etched board, the rolled separator paper needs to be cut. The size of the separator paper is determined according to the size of the inner etched board, and the cut separator paper is placed in the separator paper box. Connect several stacking boxes to the corresponding horizontal slide rails through buckles. The number of stacking boxes and horizontal slide rails is the same and one-to-one. The number of stacking boxes and horizontal slide rails needs to be determined according to the height of the conveyor belt and the height of the vertical slide rail. The bottom stacking box rises driven by the vertical slide rail to ensure that the bottom stacking box is at the same height as the conveyor belt, and ensure that the X-axis moving module can put the inner etched board into the stacking box after sucking it, and also ensure that the separator paper suction component sucks the separator paper and puts it into the stacking box.

[0054] The first vacuum suction cup repeatedly completes the suction and release of multiple inner-layer etched plates, and the second vacuum suction cup repeatedly completes the suction and release of multiple sheets of spacer paper until the first stacking box is full of inner-layer etched plates, and the vertical slide rail drives the stacking box on the first horizontal slide rail to move upward, and the first horizontal slide rail drives the first stacking box to move horizontally to the end of the first horizontal slide rail to make room for the second stacking box, and the remaining stacking boxes repeat the above operations. The stacking boxes that have completed the plate collection in advance can be located at the left end of the corresponding horizontal slide rail at the same time, or at the right end of the corresponding horizontal slide rail at the same time, or can be staggered in the left and right directions of the horizontal slide rail to ensure that the stacking boxes that need to transfer the plates for stacking next can be located at the center of the cross slide rail, ensuring that the X-axis moving module can place the inner-layer etched plate into the stacking box after sucking it, and also ensuring that the spacer paper suction component can place the spacer paper into the stacking box after sucking it.

[0055] The control system in the present invention is a programmable PC, which pre-stores the image of the correct position of the etching plate sucked by the memory, and pre-stores the image of the correct position of the stacking box. The X-axis moving module sucks the inner etching plate and needs to rely on the visual sensor at the bottom of the first vacuum suction cup to collect the image and compare it with the pre-stored image in the control system, thereby effectively helping the X-axis moving module to suck the inner etching plate and release the inner etching plate in the stacking box. The output end of the control system is connected to the input end of the X-axis moving module, the cross slide rail, the vacuum generator, the rotating motor, the first electric telescopic rod and the second electric telescopic rod, and the above-mentioned X-axis moving module, the cross slide rail, the vacuum generator, the rotating motor, the first electric telescopic rod and the second electric telescopic rod are controllable under the automation of the programmable program.

[0056] The present invention is provided with an X-axis moving module, and a first electric telescopic rod and a first vacuum suction cup are provided under the X-axis moving module, which can absorb and release the inner etching plate into the stacking box, and a paper separation suction component is provided on the mobile cart, which can quickly absorb and release the paper separation onto the inner etching plate in the stacking box, solving the problems of low automation, time-consuming and labor-intensive, high labor cost and low stacking efficiency in the existing manual placement of paper separation.
