Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing and processing technology, and in particular to a sliding blade depaneling machine for PCB boards. Background Technology

[0002] According to the patent document with publication number CN220985949U, the patent document describes a PCB substrate supported by four supports. A hydraulic cylinder drives the support block to slide within the frame, which in turn moves the hanging plate and thus the cutter. The cutter slides on the PCB substrate to cut it. When the cutter needs to be changed, a motor drives the turntable to rotate, which in turn rotates the cutter on the turntable to change it. A cylinder drives the friction ring to move and contact the turntable, which limits the turntable and facilitates the positioning of the cutter after the change of position.

[0003] The patent document states that after the cutter cuts the PCB board on the four supports once, the PCB board will fall off, which cannot meet the requirement of multiple parallel cuts of the PCB board, and the fixed position of the four supports cannot adapt to PCB boards of different specifications. Utility Model Content

[0004] The purpose of this invention is to provide a sliding blade depaneling machine for PCB boards in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A pass-through depaneling machine for PCB boards includes a machine base, a cutting mechanism on the top of the machine base, a V-groove plate on the lower side of the cutting mechanism, and a support adjustment mechanism located on the front side of the V-groove plate.

[0007] The support adjustment mechanism includes a support plate, which is fixed to the front side of the machine. A sliding frame is slidably connected to the top of the support plate. A second lead screw is threaded to one side of the sliding frame. Two symmetrical first placement plates are slidably connected to the top of the sliding frame. Each of the two first placement plates has a clamping plate on its upper side. A guide rod passing through the clamping plate is fixed to the top of the first placement plate. A spring is sleeved on the guide rod. A gear is rotatably connected to the front side of the sliding frame. A first rack is meshed on one side of the top of the gear, and a second rack is meshed on the other side of the bottom of the gear. A second placement plate is fixed to the front side of the V-groove plate.

[0008] Preferably, the cutting mechanism includes a first lead screw, which is rotatably connected to the top of the machine base. The first lead screw is externally threaded to a first sliding seat, and a separating blade is rotatably connected to the bottom of the first sliding seat.

[0009] Preferably, a first motor is fixedly installed at the input end of the first lead screw, the first sliding seat is slidably connected to the machine base, the bottom of the separating blade coincides with the top of the V-groove plate, and the V-groove plate is fixed on the machine base.

[0010] Preferably, the second lead screw is rotatably connected to the top side of the support plate, and a second motor is fixedly installed at the input end of the second lead screw.

[0011] Preferably, a guide post passing through the sliding frame is fixed to the other side of the top of the support plate.

[0012] Preferably, a groove is provided on the top side of the first placement plate near the PCB board, the top of the V-groove plate, the top of the second placement plate and the groove of the first placement plate are on the same plane, and the spring is fixed between the top of the first placement plate and the bottom of the clamping plate.

[0013] Preferably, the first rack is fixedly connected to the first placement plate on one side, and the second rack is fixedly connected to the first placement plate on the other side.

[0014] The beneficial effects compared with the existing technology are as follows: the rotation of the gear drives the first rack and the second rack to move closer to each other, thereby driving the two first placement plates to slide closer to each other in the sliding frame, which meets the placement requirements of PCB boards of different lengths. The retraction of the two springs drives the two clamping plates to move downward to clamp the PCB board. The second placement plate places the rear end of the PCB board and stably clamps PCB boards of different thicknesses. The second lead screw drives the sliding frame and the PCB board to move backward, which meets the requirement of parallel cutting of different PCB boards multiple times. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7 As shown, a sliding blade depaneling machine for PCB boards includes a machine base 1, a cutting mechanism 2 on the top of the machine base 1, a V-groove plate 3 on the lower side of the cutting mechanism 2, and a support adjustment mechanism 4 located in front of the V-groove plate 3.

[0028] In this embodiment: the support adjustment mechanism 4 includes a support plate 401, which is fixed to the front side of the machine base 1. A sliding frame 402 is slidably connected to the top of the support plate 401. A second lead screw 403 is threadedly connected to one side of the sliding frame 402. The second lead screw 403 is rotatably connected to the top side of the support plate 401. A second motor is fixedly installed at the input end of the second lead screw 403. A guide post passing through the sliding frame 402 is fixed to the other side of the top of the support plate 401. Two symmetrical first placement plates 404 are slidably connected to the top of the sliding frame 402. Each of the placement plates 404 has a clamping plate 405 on its upper side. A guide rod 406 passing through the clamping plate 405 is fixed to the top of the first placement plate 404. A spring 407 is sleeved on the guide rod 406. A gear 410 is rotatably connected to the front side of the sliding frame 402. A first rack 408 is meshed on one side of the top of the gear 410, and a second rack 409 is meshed on the other side of the bottom of the gear 410. The first rack 408 is fixedly connected to one side of the first placement plate 404, and the second rack 409 is fixedly connected to the other side of the first placement plate 404. A second placement plate is fixed to the front side of the V-groove plate 3. 411. A groove is formed on the top side of the first placement plate 404 near the PCB board. The top of the V-groove plate 3, the top of the second placement plate 411, and the groove of the first placement plate 404 are on the same plane. A spring 407 is fixed between the top of the first placement plate 404 and the bottom of the clamping plate 405. The gear 410 is driven to rotate by the fourth motor. The gear 410 meshes with the first rack 408 and the second rack 409 respectively. In turn, the gear 410 drives the first rack 408 and the second rack 409 to move closer to each other, thereby driving the two first placement plates 404. The sliding frames 402 slide closer to each other to accommodate PCBs of different lengths. Pulling the two clamping plates 405 upward stretches the two springs 407, placing the two front corners of the PCB into the grooves of the two first placement plates 404 respectively. Releasing the two clamping plates 405 causes the two springs 407 to retract, moving the two clamping plates 405 downward along the two guide rods 406 to clamp the PCB. The rear end of the PCB is placed through the second placement plate 411, and the second lead screw 403 driven by the third motor moves the sliding frame 402 and the PCB to the rear.

[0029] In this embodiment: the cutting mechanism 2 includes a first lead screw 201, which is rotatably connected to the top of the machine base 1. The first lead screw 201 is externally threaded to a first sliding seat 202. A sliding blade 203 is rotatably connected to the bottom of the first sliding seat 202. A first motor is fixedly installed at the input end of the first lead screw 201. The first sliding seat 202 is slidably connected to the machine base 1. The bottom of the sliding blade 203 coincides with the top of the V-groove plate 3. The V-groove plate 3 is fixed on the machine base 1. The first motor drives the first lead screw 201 to move the first sliding seat 202 along both sides, thereby driving the sliding blade 203 to move on the top of the V-groove plate 3. The second motor drives the sliding blade 203 to rotate and cut the PCB board.

[0030] Working principle: Based on the required length of the PCB board to be processed, the fourth motor is started to drive the gear 410 to rotate. The gear 410 meshes with the first rack 408 and the second rack 409 respectively. In turn, the gear 410 drives the first rack 408 and the second rack 409 to move closer to each other, thereby driving the two first placement plates 404 to slide closer to each other in the sliding frame 402. The two clamping plates 405 are pulled upward, and the two springs 407 are stretched, placing the two front corners of the PCB board into the grooves of the two first placement plates 404 respectively. The two clamping plates 405 are released, and the two springs 407 retract, driving the two clamping plates 405 to move downward along the two guide rods 406 to clamp the PCB board. The rear end of the PCB board is placed on the V-groove plate 3 and the second placement plate 411.

[0031] After the PCB board is placed, cutting begins. The first motor drives the first lead screw 201 to move the first sliding block 202 to one side, which in turn moves the splitting blade 203 on the top of the V-groove plate 3. The second motor drives the splitting blade 203 to rotate and cut the PCB board. After one cut is completed, according to the requirement of parallel splitting of the PCB board, the third motor drives the second lead screw 403 to move the sliding frame 402 and the PCB board to the rear side to continue the subsequent cutting.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
