Description

Technical Field

[0001] This utility model relates to the field of vertical insertion machine technology, and more specifically to the exchange board device of vertical insertion machine. Background Technology

[0002] The Panasonic RL132 vertical insertion machine from Japan uses a double-plate exchange mechanism controlled by a plate-pulling arm. Figure 1 As shown, the insertion machine has a pull-plate arm 01 with two units, left and right. The right unit has four clamping positioning blocks 02, each pair of adjacent positioning blocks clamping one PCB board, holding two PCB boards to be inserted on the machine's feed rail. The pull-plate arm then transfers the boards to the machine's worktable for positioning before insertion. Simultaneously, the left unit of pull-plate arm 01 also has four clamping positioning blocks 03, each pair of adjacent positioning blocks clamping one PCB board, holding two inserted PCB boards on the machine's worktable. The pull-plate arm then transfers these boards to the machine's lower rail, completing one PCB board exchange operation. The pull-plate arm's use of clamping positioning blocks to hold the PCB boards for exchange presents the following problems: Because PCB boards vary in length, each line change requires repositioning the clamping positioning blocks according to the PCB board length. The clamping positioning blocks are fixed to the slide rod by two M3 screws; frequent adjustments can cause the screws to sprout, increasing manual error handling time and affecting efficiency. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a vertical plug-in machine exchange board device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The vertical insertion machine's exchange plate device includes a pull plate arm, with a connecting part in the middle of the pull plate arm. The connecting part is used to connect to the drive mechanism on the vertical insertion machine, which drives the entire exchange plate device to move left and right and to lift the entire exchange plate device. The board feed track has two or more PCBs spaced apart, and each PCB has positioning holes in the same position. The two ends of the pull plate arm extend in opposite directions to form the left arm and the right arm, respectively; At least two positioning pins are spaced apart along the length of the right arm. The positioning pins are perpendicular to the right arm and the insertion end of the base of the positioning pin faces downward. Each positioning pin on the right arm corresponds to a positioning hole on each PCB board on the board feed track. At least two push plates are spaced apart along the length of the bottom of the left arm. The number of push plates is the same as the number of positioning pins. Each push plate is used to push a corresponding PCB board on the worktable. As the pull arm descends, it causes the positioning pins on its right arm to be inserted into the positioning holes of the corresponding PCB boards on the board feeding track. At the same time, the push plates on the left arm are positioned at intervals on the right side of the corresponding PCB board on the worktable. When the pull arm moves from right to left, each positioning pin drives the corresponding PCB board into the worktable to prepare for board assembly. Meanwhile, each push plate sends the corresponding and completed PCB board out of the worktable, completing one board handover operation.

[0005] Furthermore, the top of the locating pin is provided with a screw, which passes through the mounting groove on the right arm and is then locked in place by a nut.

[0006] Furthermore, the upper end of the push plate is connected to a connecting plate integrally formed therewith. The plate is secured by bolts that pass sequentially through the mounting groove on the left arm and the connecting hole on the connecting plate, and then by locking with nuts.

[0007] Furthermore, the mounting slots on both the left and right arms are elongated strips.

[0008] By adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. The right arm of the pull plate arm uses a positioning pin to hold the positioning hole on the lower left of the PCB board for board exchange. Each time a board is fed onto the board feed track, the position of the positioning hole on the lower left corner of each PCB board on the board feed track does not change. There is no need to adjust the position of the positioning pin on the pull plate arm when switching between different PCB boards, which improves efficiency and quality.

[0009] 2. Both the positioning pin and the push plate are fixed to the pull plate arm using a threaded connection assembly. Only the fixed positions of the positioning pin and the push plate need to be marked. When the positioning pin and the push plate are worn and need to be replaced, they can be replaced quickly, which is convenient and improves efficiency. Attached Figure Description

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Figure 1 This is a schematic diagram of the exchange board device on an existing vertical insertion machine; Figure 2 This is a top view schematic diagram of the present invention (the exchange plate device is offset from the infeed rail and the worktable for easy viewing of the structural connection relationship). Figure 3 This is a front view of the pull plate arm; Figure 4 This is a schematic diagram showing the positions of PCBs of different lengths on the board feed track. Detailed Implementation

[0011] This utility model relates to a vertical insertion machine exchange plate device, which modifies the structure of the upper pull plate arm of the existing Panasonic RL132 vertical insertion machine. For example... Figure 2-3 As shown, this utility model specifically includes a pull plate arm 1, with a connecting part 11 in the middle. The connecting part 11 is used to connect to the drive mechanism on the vertical insertion machine. The drive mechanism includes a transverse module and a lifting driver located on the transverse module. The transverse module drives the entire exchange plate device to move back and forth between the plate infeed track and the worktable. The lifting driver (cylinder) drives the entire exchange plate device to descend and rise. This part is the same as the prior art, and the specific connection structure will not be described in detail.

[0012] Two or more PCBs (to be manufactured) are spaced apart on the board feeding track. Each PCB has a positioning hole 4 in the same position. The same position means that, assuming the lower left corner of the PCB is the zero point, the center of the positioning hole 4 is in the same position relative to the zero point.

[0013] The two ends of the pull plate arm 1 extend in opposite directions to form a left arm 12 and a right arm 13, respectively; At least two positioning pins 2 are provided at intervals along the length of the right arm 13. The positioning pins 2 are perpendicular to the right arm 13 and the insertion end 21 at the root of the positioning pin 2 is set downward. Each positioning pin 2 on the right arm 13 is set to correspond one-to-one with the positioning hole 4 on each PCB board on the board entry track. At least two push plates 3 are provided at intervals along the length direction at the bottom end of the left arm 12. The number of push plates 3 is the same as the number of positioning pins 2. Each push plate 3 is used to push a corresponding PCB board on the worktable.

[0014] In this utility model, the top of the positioning pin 2 is provided with a screw 22, which passes through the mounting groove 131 on the right arm 13 and is then locked and fixed by a nut.

[0015] The upper end of the push plate 3 is connected to a connecting plate 31 integrally formed therewith. The plate is secured by bolts that pass through the mounting groove 121 on the left arm 12 and the connecting hole on the connecting plate 31 in sequence, and are then locked in place by nuts.

[0016] The mounting slots 121 and 131 on the left arm 12 and right arm 13 are both elongated structures, which allows the positioning pin 2 and the push plate 3 to also have position adjustment functions.

[0017] In one embodiment, during the feeding process, two PCBs of the same model enter the feeding track at a time and remain intermittently on the track. The positioning hole 4 is designed at the lower left corner of the PCB. When this utility model is in operation, the pull arm 1 descends, causing the two positioning pins 2 on its right arm 13 to be inserted into the positioning holes 4 of the corresponding (to be manufactured) PCBs on the feeding track. At the same time, the two push plates 3 on the left arm 12 are positioned at intervals on the right side of the corresponding (finished) PCBs on the worktable. As the pull arm 1 moves from right to left, each positioning pin 2 drives the corresponding PCB to be sent into the worktable for manufacturing. Simultaneously, each push plate 3 sends the corresponding finished PCB out of the worktable, completing one board handover operation. Then, the pull arm 1 resets, ready for the next board handover operation.

[0018] The position sensor controls the descent position of the pull plate arm 1 to ensure that the positions of the push plate 3 and the positioning pin 2 are not too low. This ensures that the push plate 3 can effectively push the PCB board while the bottom of the push plate 3 does not touch the worktable surface, and that the positioning pin 2 can effectively insert into the positioning hole 4 of the PCB board while the bottom of the positioning pin 2 does not touch the worktable surface.

[0019] When the production line changes to PCBs of different lengths, position sensors are designed on the board feed track to control the position of the PCBs in the feed track. For example, if two PCBs are conveyed to the board feed track at intervals and stop there, the left side of each PCB in the feed track will remain fixed each time. The difference in PCB length will only affect the right side of the PCB. Figure 4 (The position of the dotted line in the middle) Therefore, the change of the PCB board length will not change the position of the positioning hole 4 on the left and lower left corners on the board entry track. Therefore, when switching PCB boards of different materials, there is no need to adjust the position of the pin on the pull arm 1.

[0020] There is a gap between the pusher board 3 and the right edge of the finished PCB board on the corresponding worktable (the pusher board 3 must pass through this gap before touching and pushing the PCB board) to accommodate pusher boards with different board lengths. For example, when the pusher board is used to push the shortest PCB board, there is a 50mm space between the pusher board and the right edge of the PCB board. Therefore, it can be adapted to PCB boards with a length increase of less than 50mm without adjusting the position of the pusher board 3.

[0021] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
