Description

Technical Field

[0001] This invention relates to the technical field of separating semi-finished circuit boards, and in particular to a separating device and method for separating semi-finished circuit boards. Background Technology

[0002] The structure of a semi-finished circuit board produced in a certain workshop is as follows: Figures 1-2 As shown, the semi-finished circuit board mainly includes two printed circuit boards 1, with a strip-shaped rib 2 formed between the two printed circuit boards 1. A V-shaped groove 3 is formed on the top surface of the strip-shaped rib 2 along its length, and the two printed circuit boards 1 are symmetrical about the V-shaped groove 3.

[0003] After the workshop produces a batch of such semi-finished circuit boards, the process requires cutting the strip-shaped stiffeners 2 of the semi-finished circuit boards to complete the separation of the semi-finished circuit boards, thereby obtaining two independent printed circuit boards 1, which can then be further processed by subsequent processing equipment.

[0004] The method by which workers in the workshop separate a batch of semi-finished circuit boards is as follows:

[0005] S1. The worker takes out a piece from the material basket. Figures 1-2 The semi-finished circuit board shown is placed with its left side printed circuit board 1 flat on the vacuum suction cup A4 of the cutting machine, as shown. Figure 3 As shown, ensure that the right printed circuit board 1 of the semi-finished circuit board is outside the vacuum chuck A4;

[0006] S2. The worker adjusts the position of the semi-finished circuit board to ensure that the V-groove 3 of the strip rib plate 2 of the semi-finished circuit board is exactly opposite to the cutting blade of the cutting machine, so as to complete the positioning of the semi-finished circuit board.

[0007] S3. The worker turns on the vacuum pump A5 connected to the vacuum suction cup A4. The vacuum pump A5 evacuates the inner cavity of the vacuum suction cup A4. Under negative pressure, the printed circuit board 1 on the left side of the semi-finished circuit board is adsorbed and fixed on the vacuum suction cup A4.

[0008] S4. The worker controls the cutting blade of the cutting machine to rotate around its own circumference, and then controls the cutting blade to move forward. The cutting blade cuts from the V-groove 3 of the strip rib plate 2. When the cutting blade passes through the strip rib plate 2, it can cut the strip rib plate 2, thus completing the separation of the first semi-finished circuit board and obtaining two required printed circuit boards 1.

[0009] S5. Workers repeat steps S1 to S4 multiple times to separate multiple semi-finished circuit boards, thereby obtaining the required number of printed circuit boards 1.

[0010] However, while the methods used by the workers in the workshop are able to separate the semi-finished circuit boards, they still have the following technical shortcomings:

[0011] I. In step S2, the worker needs to adjust the position of the semi-finished circuit board multiple times so that the V-groove 3 of the semi-finished circuit board is aligned with the cutting blade of the cutting machine, so as to complete the positioning of the semi-finished circuit board. Adjusting the position of the semi-finished circuit board takes a long time, which means that it takes a long time to complete the positioning of the semi-finished circuit board, thereby reducing the efficiency of separating the semi-finished circuit board.

[0012] II. In step S4, when the cutting blade is cutting the strip rib plate 2, a large amount of powdery waste is generated. The powdery waste flies around and falls onto the surface of the printed circuit board 1, which means that workers have to clean up the powdery waste later, which undoubtedly increases the workload of the workers.

[0013] Therefore, there is an urgent need for a board separation device and method that can greatly improve the efficiency of separating semi-finished circuit boards and prevent the generation of powdery waste during the separation process. Summary of the Invention

[0014] The purpose of this invention is to overcome the shortcomings of the prior art and provide a board separation device and method for separating semi-finished circuit boards.

[0015] The objective of this invention is achieved through the following technical solution: a board separating device for separating semi-finished circuit boards, comprising a worktable fixed on a pad, two positioning and fixing components for positioning and adsorbing the semi-finished circuit boards are provided on the worktable surface, the two positioning and fixing components have the same structure, the positioning and fixing component on the left side includes a column fixed on the worktable surface, a rotating plate hinged to the top of the column via a first pin, a connecting rod hinged to the left end of the bottom surface of the rotating plate via a second pin, the connecting rod being located on the left side of the column, a strip positioning platform and a vacuum suction cup B are fixed on the top surface of the rotating plate, the strip positioning platform being located on the left side of the vacuum suction cup B, and a longitudinally arranged positioning stop is provided on the inner end face of the strip positioning platform;

[0016] The vacuum suction cup B has multiple suction holes connected to its inner cavity in the top wall. The right end of the vacuum suction cup B extends to the right outside the rotating plate, and a vacuum pump B is fixed on the bottom surface of the extended end. The working port of the vacuum pump B is connected to the inner cavity of the vacuum suction cup B. The pad is provided with a pull-down assembly for pulling down the connecting rods of the two positioning and fixing components.

[0017] The two positioning and fixing components are symmetrical.

[0018] The longitudinal width of the positioning stop of the strip positioning stage is equal to the longitudinal width of the printed circuit board of the semi-finished circuit board.

[0019] The adsorption pores are arranged in a rectangular array on the vacuum suction cup B.

[0020] The pull-down assembly includes a pull-down cylinder fixed on the pad, a floating plate fixed on the piston rod of the pull-down cylinder, and a rod fixed on both the left and right ends of the floating plate. Both rods extend upward through the worktable and have concave brackets fixed on their extended ends. The two concave brackets are respectively hinged to the connecting rods of the two positioning and fixing assemblies via a third pin.

[0021] The pull-down assembly also includes a sliding seat fixed to the bottom surface of the floating plate and two guide light rods fixed to the bottom surface of the worktable. The guide light rods slide down through the floating plate and the sliding seat.

[0022] The separation device also includes a controller, which is electrically connected to vacuum pump B and pull-down cylinder via signal lines.

[0023] A method for separating semi-finished circuit boards includes the following steps:

[0024] S1. The worker takes out a semi-finished circuit board to be separated and inserts the left end of the left printed circuit board of the semi-finished circuit board into the positioning stop of the strip positioning table of the left positioning and fixing component from top to bottom. At the same time, the right end of the right printed circuit board of the semi-finished circuit board is inserted into the positioning stop of the strip positioning table of the right positioning and fixing component from top to bottom, thereby realizing the positioning of the semi-finished circuit board. At this time, the two printed circuit boards of the semi-finished circuit board are supported on the top surfaces of the two vacuum suction cups B respectively. Meanwhile, the V-shaped groove of the semi-finished circuit board is exactly in the center of the area enclosed by the two vacuum suction cups B.

[0025] S2. The worker controls the vacuum pump B of the two positioning and fixing components to start. The vacuum pump B evacuates the inner cavity and suction hole of the corresponding vacuum suction cup B. Under negative pressure, the two printed circuit boards of the semi-finished circuit board are respectively suctioned and fixed on the top surface of the two vacuum suction cups B.

[0026] S3. The worker controls the piston rod of the pull-down cylinder of the pull-down assembly to retract downwards. The piston rod drives the floating plate to move downwards. The floating plate moves downwards in a straight line along the guide light rod. At the same time, the floating plate also drives two rods to move downwards synchronously. The rods drive the concave bracket to move downwards. The concave bracket drives the connecting rod to move downwards. The connecting rod drives the rotating plate to rotate upwards around the first pin axis. The rotating plate drives the strip positioning stage, vacuum suction cup B and vacuum pump B to rotate upwards synchronously, thereby driving the printed circuit board that is adsorbed and fixed to move upwards synchronously.

[0027] When the piston rod of the pull-down cylinder is fully retracted, the strip-shaped ribs of the two printed circuit boards are broken off from the weakest V-groove, thus completing the separation of the first semi-finished circuit board and obtaining two independent printed circuit boards.

[0028] S4. Removal of the two printed circuit boards: The worker controls the vacuum pump B of the two positioning and fixing components to turn off. At this time, the vacuum suction cup B no longer holds the printed circuit board, and then the worker removes the two independent printed circuit boards from the vacuum suction cup B.

[0029] S5. Workers repeat steps S1 to S4 multiple times to separate multiple semi-finished circuit boards, thereby obtaining the required number of printed circuit boards.

[0030] The present invention has the following advantages: it greatly improves the efficiency of separating semi-finished circuit boards and does not generate powdery waste during the separation process. Attached Figure Description

[0048] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0049] like Figures 4-10 As shown, a board separating device for separating semi-finished circuit boards includes a worktable 7 fixed on a pad 6. Two positioning and fixing components 8 for positioning and adsorbing the semi-finished circuit boards are arranged on the worktable 7. The two positioning and fixing components 8 have identical structures and are symmetrical. The positioning and fixing component 8 on the left includes a column 9 fixed on the worktable 7 and a rotating plate 11 hinged to the top of the column 9 via a first pin 10. A connecting rod 13 is hinged to the left end of the bottom surface of the rotating plate 11 via a second pin 12. The connecting rod 13 is located to the left of the column 9. A strip-shaped positioning platform 14 and a vacuum suction cup B15 are fixed on the top surface of the rotating plate 11. The strip-shaped positioning platform 14 is located to the left of the vacuum suction cup B15. A longitudinally arranged positioning stop 16 is opened on the inner end face of the strip-shaped positioning platform 14. The longitudinal width of the positioning stop 16 of the strip-shaped positioning platform 14 is equal to the longitudinal width of the printed circuit board 1 of the semi-finished circuit board.

[0050] The vacuum suction cup B15 has multiple adsorption holes 17 connected to its inner cavity in the top wall. The adsorption holes 17 are arranged in a rectangular array on the vacuum suction cup B15. The right end of the vacuum suction cup B15 extends to the right outside the rotating plate 11, and a vacuum pump B18 is fixed on the bottom surface of the extended end. The working port of the vacuum pump B18 is connected to the inner cavity of the vacuum suction cup B15. The pad plate 6 is provided with a pull-down assembly for pulling down the connecting rods 13 of the two positioning and fixing components 8.

[0051] The pull-down assembly includes a pull-down cylinder 19 fixed to the pad 6 and a floating plate 20 fixed to the piston rod actuating end of the pull-down cylinder 19. A rod 21 is fixed to both the left and right ends of the floating plate 20. Both rods 21 extend upwards through the worktable 7, and concave supports 22 are fixed to their extended ends. The two concave supports 22 are respectively hinged to the connecting rods 13 of the two positioning and fixing components 8 via a third pin 23. The pull-down assembly also includes a sliding seat 24 fixed to the bottom surface of the floating plate 20 and two guide rods 25 fixed to the bottom surface of the worktable 7. The guide rods 25 slide downwards through the floating plate 20 and the sliding seat 24.

[0052] The panel separation device also includes a controller, which is electrically connected to the vacuum pump B18 and the pull-down cylinder 19 via a signal line. The operator can control the start or stop of the vacuum pump B18 through the controller, and at the same time, can also control the extension or retraction of the piston rod of the pull-down cylinder 19, thereby facilitating the operator's operation.

[0053] A method for separating semi-finished circuit boards includes the following steps:

[0054] S1, the worker takes out a... Figures 1-2 The semi-finished circuit board to be separated is shown. The left end of the left printed circuit board 1 of the semi-finished circuit board is inserted from top to bottom into the positioning stop 16 of the strip positioning table 14 of the left positioning and fixing component 8. At the same time, the right end of the right printed circuit board 1 of the semi-finished circuit board is inserted from top to bottom into the positioning stop 16 of the strip positioning table 14 of the right positioning and fixing component 8. Since the longitudinal width of the positioning stop 16 of the strip positioning table 14 is equal to the longitudinal width of the printed circuit board 1 of the semi-finished circuit board, the positioning of the semi-finished circuit board is achieved. At this time, the two printed circuit boards 1 of the semi-finished circuit board are respectively supported on the top surface of the two vacuum suction cups B15. At the same time, the V-groove 3 of the semi-finished circuit board is exactly at the center of the area enclosed by the two vacuum suction cups B15.

[0055] As can be seen from step S1, the worker only needs to place the semi-finished circuit board between the positioning stops 16 of the strip positioning table 14 of the two positioning and fixing components 8 to quickly position the semi-finished circuit board, thereby quickly placing the semi-finished circuit board at the board separation station.

[0056] Therefore, it can be seen that this plate separating device is superior to... Figure 3 The board separation method shown eliminates the need for workers to repeatedly adjust the position of the semi-finished circuit board to align the V-groove 3 of the semi-finished circuit board with the cutting blade of the cutting machine. Instead, the semi-finished circuit board can be positioned simply by placing it in place, thereby shortening the board separation time and greatly improving the board separation efficiency.

[0057] S2. The worker controls the vacuum pump B18 of the two positioning and fixing components 8 to start. The vacuum pump B18 evacuates the inner cavity and suction hole 17 of the corresponding vacuum suction cup B15. Under negative pressure, the two printed circuit boards 1 of the semi-finished circuit board are respectively suctioned and fixed on the top surface of the two vacuum suction cups B15.

[0058] S3. The worker controls the piston rod of the pull-down cylinder 19 of the pull-down assembly to retract downwards. The piston rod drives the floating plate 20 to move downwards. The floating plate 20 moves downwards in a straight line along the guide light rod 25. At the same time, the floating plate 20 also drives the two rods 21 to move downwards synchronously. The rods 21 drive the concave bracket 22 to move downwards. The concave bracket 22 drives the connecting rod 13 to move downwards. The connecting rod 13 drives the rotating plate 11 to rotate upwards around the first pin 10. The rotating plate 11 drives the strip positioning stage 14, the vacuum suction cup B15 and the vacuum pump B18 to rotate upwards synchronously, thereby driving the printed circuit board 1 that is adsorbed and fixed to move upwards synchronously.

[0059] When the piston rod of the pull-down cylinder 19 is fully retracted, the strip ribs 2 of the two printed circuit boards 1 are broken off from the weakest V-groove 3, thus completing the separation of the first semi-finished circuit board and obtaining two independent printed circuit boards 1.

[0060] S4. Removal of the two printed circuit boards 1: The worker controls the vacuum pump B18 of the two positioning and fixing components 8 to turn off. At this time, the vacuum suction cup B15 no longer holds the printed circuit board 1, and then the worker removes the two independent printed circuit boards 1 from the vacuum suction cup B15.

[0061] S5. Workers repeat steps S1 to S4 multiple times to separate multiple semi-finished circuit boards, thereby obtaining the required number of printed circuit boards 1.

[0062] In step S1, the two strip positioning platforms 14 of the two positioning and fixing components 8 are used to position the semi-finished circuit board. In step S2, the vacuum pump B18 is started to make the two printed circuit boards 1 of the semi-finished circuit board adsorb and fix them on the two vacuum suction cups B15 respectively. In step S3, the piston rod of the pull-down cylinder 19 of the pull-down component is controlled to retract downward so that the two printed circuit boards 1 of the semi-finished circuit board rotate upward synchronously, thereby breaking the strip rib 2 between the two printed circuit boards 1 and completing the board separation action.

[0063] Therefore, it can be seen that the strip-shaped reinforcing plate 2 between the two printed circuit boards 1 is broken at the weakest V-shaped groove 3. During the breaking process, no powdery waste is generated, and therefore no powdery waste falls onto the surface of the printed circuit board 1. Compared to... Figure 3 The board separation method shown eliminates the need for workers to clean the powdery waste on the surface of the printed circuit board 1 afterward, thus greatly reducing the workload of workers.
