Description

Technical Field

[0001] The utility model belongs to the technical field of PCB board processing equipment and relates to a PCB board inserting mechanism. Background Art

[0002] There are several special processes in the production of PCB boards. Products cannot be directly stacked or touched, but must be inserted into special racks in individual pieces. As the PCB board is inserted into the slot of the rack, the deeper the insertion, the fewer clamping positions are available for the board insertion unit to clamp the PCB board. Therefore, at present, most of them adopt the edge clamping method, that is, two clamping heads clamp the side edges of the PCB board respectively, so that the clamping position does not need to be changed during the entire board insertion process. However, this clamping method has problems such as "shaking" of the PCB board during the clamping and movement process and low clamping accuracy. Especially for the clamping of thin boards, it is easy to cause faults such as inaccurate board position, board surface deformation during the board insertion process, and wrong slot insertion. Utility Model Content

[0003] The purpose of the utility model is to provide a PCB board insertion mechanism in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the stability and reliability of the clamping plate when inserting the board.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a PCB board plug-in mechanism, characterized in that it includes a base and two plug-in units respectively located on both sides of the base, the plug-in unit including a synchronous belt, a vertical guide rail arranged on the base, a limit plate fixed on the synchronous belt and a plurality of slides slidably connected to the vertical guide rail, the slide is provided with a pneumatic clamp, the upper end of the slide is provided with a limit arm, the limit arm is provided with a strong magnetic adsorption head, the limit plate is provided with a magnetic attraction positioning block adapted to each strong magnetic attraction head, the base is provided with a limit head for limiting the upper and lower movement of the slide at the lower end on the vertical guide rail; the relative position of two adjacent limit arms is: when the slide at a higher position moves up and down on the vertical track relative to the slide at a lower position, the slide at a higher position is limited by the slide at a lower position, so that the corresponding strong magnetic attraction head is separated from the magnetic attraction positioning block.

[0005] Furthermore, the distance between the two plug-in board units is adjustable.

[0006] Furthermore, there are three slide plates on the plugboard unit.

[0007] The working process of this rack-mounted retractable board machine is as follows:

[0008] Inserting board: The suction cup unit on the six-axis robot takes the PCB board on the board input conveyor line to the inserting board mechanism by adsorbing the surface of the PCB board. The pneumatic clamp on the inserting board mechanism clamps the edge of the PCB board and inserts the PCB board into the rack on the outfeed conveyor line. Every time a board is inserted, the outfeed conveyor line moves the rack forward one inserting board interval until the rack is fully loaded. The fully loaded rack is discharged from the outfeed conveyor line, received and transferred by the outfeed vehicle, and a new empty rack enters the inserting board station. This cycle is repeated to complete the inserting board.

[0009] The specific process of multi-point clamping edge plug-in board is as follows: in the initial state, each slide plate is in a high position, each strong magnetic adsorption head on the limit plate and each magnetic attraction positioning block on the upper limit arm of the slide plate are in an adsorption state, and after the pneumatic clamp on the slide plate clamps the PCB board, the synchronous belt controls the limit plate to move downward, and each slide plate also moves downward synchronously. When the bottom slide plate moves to abut against the limit head, the bottom slide plate cannot move further downward, and the corresponding strong magnetic adsorption head is separated from the magnetic attraction positioning block, and the pneumatic clamp on the slide plate releases the PCB board and then becomes stationary, while other slide plates continue to move downward. When the stationary slide plate limits its upper When the first slide plate is pushed, the corresponding strong magnetic adsorption head is separated from the magnetic positioning block, the pneumatic clamp on the second slide plate also releases the PCB board, and the second slide plate also stops. According to this logic, when all slide plates stop, the PCB board completes the board insertion action, the synchronous belt reverses, and all slide plates are pushed up to the initial state. This cycle completes the board insertion operation of all PCB boards. This method can achieve multi-point clamping, especially in the board insertion operation of thin plates, the position of the PCB board is accurate, while the traditional method generally clamps one side of the PCB board, and the PCB board is easily damaged by misalignment, shaking or misalignment during the insertion process.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1-Figure 3As shown, the plug-in mechanism includes a base and two plug-in units respectively located on both sides of the base, the plug-in unit includes a synchronous belt 11, a vertical guide rail 12 arranged on the base, a limit plate fixed on the synchronous belt 11 and a plurality of slides 13 slidably connected to the vertical guide rail 12, a pneumatic clamp 14 is arranged on the slide 13, a limit arm 15 is provided at the upper end of the slide 13, a strong magnetic adsorption head 16 is provided on the limit arm 15, a magnetic attraction positioning block 17 adapted to each strong magnetic adsorption head 16 is provided on the limit plate, and a limit head 18 is provided on the base for limiting the upper and lower movement of the lowermost slide 13 on the vertical guide rail 12; the relative position of two adjacent limit arms 15 is as follows: when the slide 13 at a higher position moves up and down on the vertical track relative to the slide 13 at a relatively lower position, the slide 13 at a higher position is limited by the slide 13 at a lower position, so that the corresponding strong magnetic adsorption head 16 is separated from the magnetic attraction positioning block 17.

[0016] The distance between the two plug-in board units is adjustable, that is, the distance between the two plug-in board units is adjusted by a screw rod.

[0017] There are three slide plates 13 on the plugboard unit.

[0018] Inserting board: The suction cup unit on the six-axis robot takes the PCB board to the inserting board mechanism by adsorbing the surface of the PCB board. The pneumatic clamp 14 on the inserting board mechanism clamps the edge of the PCB board and inserts the PCB board into the rack on the discharge conveyor line. Every time a board is inserted, the discharge conveyor line moves the rack forward one inserting board interval until the rack is fully loaded. The fully loaded rack is discharged from the discharge conveyor line.

[0019] The specific process of the multi-point clamping edge plug-in plate is as follows: in the initial state, each slide plate 13 is in a high position, each strong magnetic adsorption head 16 on the limit plate and each magnetic positioning block 17 on the upper limit arm 15 of the slide plate 13 are in an adsorption state, and after the pneumatic clamping claw 14 on the slide plate 13 clamps the PCB board, the synchronous belt 11 controls the limit plate to move downward, and each slide plate 13 also moves downward synchronously. When the lowest slide plate 13 moves to abut against the limit head 18, the lowest slide plate 13 cannot continue to move downward, and the corresponding strong magnetic adsorption head 16 is disengaged from the magnetic positioning block 17, and the pneumatic clamping claw 14 on the slide plate 13 releases the PCB board and then is in a stationary state, while the other slide plates 13 continue to move downward. When it is stationary, When the slider 13 restricts the slider 13 on it, the corresponding strong magnetic adsorption head 16 is separated from the magnetic positioning block 17, and the pneumatic clamping claw 14 on the second slider 13 also releases the PCB board, and the second slider 13 also stops. According to this logic, when all the sliders 13 stop, the PCB board completes the board insertion action, and the synchronous belt 11 reverses to push all the sliders 13 to the initial state. This cycle completes the board insertion operation of all PCB boards; this method can achieve multi-point clamping, especially in the board insertion operation of thin plates, the position of the PCB board is accurate, while the traditional method generally clamps one side of the PCB board, and the PCB board is easily damaged by misalignment or shaking or misalignment during the insertion process.

[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
