Description

Technical Field

[0001] This utility model belongs to the technical field of PCB processing equipment, and in particular relates to an automatic PCB glue cutting machine. Background Technology

[0002] In the manufacturing process of PCBs (Printed Circuit Boards), pins and tape are typically used to secure the PCB board and its backing plates. Before subsequent processing steps, the pins need to be removed and the tape peeled off. Traditional manual methods are inefficient, labor-intensive, and prone to damaging the PCB board, affecting product quality. While some PCB tape-cutting machines exist on the market, their functionality is insufficient, failing to achieve fully automated operations such as loading, pin removal, tape cutting, copper plate separation, and backing plate unloading, making it difficult to meet the demands of large-scale production.

[0054] In one embodiment of this utility model, such as Figures 1-13 As shown, an automatic PCB cutting machine is provided, including a frame 1, a feeding device 2, a pin removal device 3, a cutting device 4, a copper plate separation device 5, and a backing plate unloading device 6. The feeding device 2, pin removal device 3, cutting device 4, copper plate separation device 5, and backing plate unloading device 6 are sequentially connected to the frame 1. The pin removal device 3 includes a pin removal mechanism 31, a flipping mechanism 32, and a detection mechanism 33. The pin removal mechanism 31 is located on one side of the detection mechanism 33, and the flipping mechanism 32 is located on one side of both the pin removal mechanism 31 and the detection mechanism 33. The cutting device 4 includes a cutting mechanism 41 and a cutting rotation mechanism 42. The copper plate separation device 5 includes a separation conveying mechanism 51, a first conveying mechanism 52, and a second conveying mechanism 53. Both the first conveying mechanism 52 and the second conveying mechanism 53 are located above the separation conveying mechanism 51, and the first conveying mechanism 52 and the second conveying mechanism 53 are arranged sequentially. The pad unloading device 6 includes an unloading platform 61 and an unloading mechanism 62. The unloading platform 61 is located on one side of the frame 1, and the unloading mechanism 62 is connected to the unloading platform 61. The automatic PCB cutting machine of this application, through the sequentially arranged feeding device 2, pin removal device 3, cutting device 4, copper plate separation device 5, and pad unloading device 6, achieves fully automated operation of the PCB board from feeding to completing cutting, copper plate separation, and pad unloading, greatly improving production efficiency and reducing labor costs. The detection mechanism 33 in the pin removal device 3 ensures the accuracy of the pin removal operation. The cutting device 4 uses a laser emitter for cutting, resulting in good cutting effect without damaging the PCB board.

The pad unloading device 6 enables automatic unloading of the pad. The entire equipment has a compact structure, stable operation, and good market application prospects.

[0055] In another embodiment of this utility model, such as Figure 2As shown, the feeding device 2 includes a material rack 21 and a feeding robot 22. Both the material rack 21 and the feeding robot 22 are fixedly connected to the frame 1. The feeding robot 22 includes a feeding X-axis module 221, a feeding Y-axis module 222, a feeding Z-axis module 223, and a feeding suction cup 224. The feeding X-axis module 221 is fixedly connected to the frame 1. The feeding Y-axis module 222 is slidably connected to the feeding X-axis module 221. The feeding Z-axis module 223 is slidably connected to the feeding Y-axis module 222. The feeding suction cup 224 is fixedly connected to the feeding Z-axis module 223. The feeding Z-axis module 223 drives the feeding suction cup 224 to move up and down.

[0056] The working process of the feeding device 2 is as follows:

[0057] The PCB boards to be processed are neatly placed on the material rack 21. Simultaneously, the modules of the loading robot 22 return to their preset initial positions: the loading X-axis module 221, loading Y-axis module 222, and loading Z-axis module 223, with the loading suction cup 224 at a suitable starting height. Based on a preset program or sensor feedback, the loading X-axis module 221 and loading Y-axis module 222 begin working collaboratively. The loading Y-axis module 222 slides along the loading X-axis module 221, and the loading X-axis module 221 itself moves accordingly, allowing the loading Z-axis module 223 and its connected loading suction cup 224 to be precisely positioned directly above the PCB board to be gripped on the material rack 21. The loading Z-axis module 223 activates, driving the loading suction cup 224 to move downwards until it contacts the surface of the PCB board. Then, the loading suction cup 224 activates its suction function, firmly gripping the PCB board. The loading Z-axis module 223 operates again, driving the loading suction cup 224 to lift the PCB board along with it, separating the PCB board from the material rack 21 to prevent collisions during subsequent movement. The loading X-axis module 221 and loading Y-axis module 222 then work together again. The loading Y-axis module 222 slides along the loading X-axis module 221, and the loading X-axis module 221 itself moves accordingly, transporting the gripped PCB board to the designated processing position, such as the detection mechanism 33 of the pin removal device 3. Once the PCB board is transported to the designated position, the loading Z-axis module 223 drives the loading suction cup 224 to descend, placing the PCB board in the designated position. Then, the loading suction cup 224 deactivates its suction function, releasing the PCB board. After the PCB board is placed, the loading X-axis module 221, loading Y-axis module 222, and loading Z-axis module 223 drive the loading suction cup 224 back to its initial position, preparing for the next loading operation.

[0058] In another embodiment of this utility model, such as Figures 3-5As shown, the PIN ejection mechanism 31 includes a PIN ejection bracket 311, a PIN ejection cylinder 312, and a PIN ejection pin 313. The PIN ejection bracket 311 is fixedly connected to the frame 1, the PIN ejection cylinder 312 is fixedly connected to the PIN ejection bracket 311, and the PIN ejection pin 313 is fixedly connected to the PIN ejection cylinder 312. The PIN ejection cylinder 312 drives the PIN ejection pin 313 to move up and down.

[0059] The working process of the PIN return mechanism 31 is as follows:

[0060] The PCB board with the PIN pins installed is placed on the detection fixture 331 of the detection mechanism 33, ensuring that the PIN pins on the PCB board are aligned with the PIN ejection hole and the PIN ejection pin 313 in the center of the detection fixture 331. At this time, the PIN ejection cylinder 312 is in its initial state, and the PIN ejection pin 313 is in a lower position and not in contact with the PCB board. When the PCB board is in place and the photoelectric sensor detects that the PIN pins on the PCB are in position, the PIN ejection cylinder 312 starts to work, and its internal piston moves downward under the action of air pressure or hydraulic pressure. Since the PIN ejection pin 313 is fixedly connected to the PIN ejection cylinder 312, when the piston of the PIN ejection cylinder 312 moves downward, it will drive the PIN ejection pin 313 to descend synchronously. The PIN ejection pin 313 passes through the PIN ejection hole on the detection fixture 331, gradually approaching and contacting the PIN pins on the PCB board. As the PIN ejection pin 313 continues to descend, it applies a downward force to the PIN pins, eventually pushing the PIN pins out of the PCB board.

[0061] In another embodiment of this utility model, such as Figures 6-7 As shown, there are two flipping mechanisms 32, which are arranged in parallel and opposite directions. Each flipping mechanism 32 includes a flipping bracket 321, a flipping motor 322, a flipping pulley 323, a flipping belt 324, a flipping slide rail 325, a flipping slider 326, a flipping slide block 327, a flipping motor, and a clamping cylinder 328. The flipping bracket 321 is fixedly connected to the frame 1. The flipping motor 322 is fixedly connected to the flipping bracket 321. The flipping pulley 323 is fixedly connected to the flipping motor 322. The flipping belt 324 is fixedly wound around the flipping pulley 323. The flipping slide rail 325 is fixedly connected to the flipping bracket 321. The flipping slider 326 is slidably connected to the flipping slide rail 325 and fixedly connected to the flipping belt 324. The flipping slide block 327 is fixedly connected to the flipping slider 326. The flipping motor is fixedly connected inside the flipping slide block 327 and fixedly connected to the clamping cylinder 328.

[0062] The working process of the flipping mechanism 32 is as follows:

[0063] The PCB board, after the pin removal operation, is transported to a suitable position between two parallel and opposite flipping mechanisms 32. At this time, the flipping motor 322 and the rotation motor are stopped, the clamping cylinder 328 is not activated, and all components are in their initial positions. The clamping cylinder 328 is activated. The clamping cylinder 328 actuates, its piston rod extends, and drives the clamping component to firmly clamp the PCB board, ensuring that the PCB board will not loosen or fall off during subsequent movement and flipping. The flipping motor 322 is activated, and the flipping motor 322 begins to rotate, driving the flipping pulley 323, which is fixedly connected to it, to rotate. Since the flipping belt 324 is fixedly wound around the flipping pulley 323, the rotation of the flipping pulley 323 will drive the flipping belt 324 to move. Since the flipping slider 326 is fixedly connected to the flipping belt 324, and the flipping slider 326 is slidably connected to the flipping slide rail 325, the movement of the flipping belt 324 will drive the flipping slider 326 to move along the flipping slide rail 325. As the flipping slider 326 moves, the flipping slide block 327, which is fixedly connected to it, also moves synchronously, thereby driving the clamping cylinder 328, which clamps the PCB board, and the PCB board as a whole to move in position, moving the PCB board to the appropriate flipping position. When the PCB board moves to the designated flipping position, the flipping motor 322 stops rotating. Then, the flipping motor is started, and its output shaft rotates. Since the flipping motor is fixedly connected to the clamping cylinder 328, the rotation of the flipping motor will drive the clamping cylinder 328 and the clamped PCB board to rotate 180 degrees around the rotation axis of the flipping motor, thereby realizing the flipping operation of the PCB board and ensuring the consistency of the material orientation. The flipping bracket 321 is equipped with a detection sensor for detecting the orientation of the material.

[0064] In another embodiment of this utility model, the detection mechanism 33 includes a detection fixing base 331 and a photoelectric sensor. The detection fixing base 331 is fixedly connected to the PIN ejection bracket 311. A PIN ejection hole is provided in the middle of the detection fixing base 331, located below and overlapping the PIN ejection pin 313. The photoelectric sensor is disposed within the PIN ejection hole and fixedly connected to the detection fixing base 331. Based on the light-sensing characteristics of the photoelectric sensor, the PIN pin is determined to be ejected by judging the degree of light obstruction within the PIN ejection hole.

[0065] In another embodiment of this utility model, the rubber tapping mechanism 41 includes a rubber tapping conveying assembly 43, a rubber tapping base 44, and a laser emitter. Both the rubber tapping conveying assembly 43 and the rubber tapping base 44 are fixedly connected to the frame 1, and the laser emitter is fixedly connected to the rubber tapping base 44. The rubber tapping conveying assembly 43 includes a rubber tapping conveyor frame 431, a rubber tapping conveyor motor 432, a rubber tapping conveyor pulley 433, and a rubber tapping conveyor belt 434. The rubber tapping conveyor frame 431 is fixedly connected to the frame 1, the rubber tapping conveyor motor 432 is fixedly connected to the rubber tapping conveyor frame 431, the rubber tapping conveyor pulley 433 is fixedly connected to the rubber tapping conveyor motor 432, and the rubber tapping conveyor belt 434 is fixedly wound around the rubber tapping conveyor pulley 433. Two rubber tapping bases 44 are provided and arranged parallel to each other. The rubber tapping conveyor belt 434 is disposed between the two rubber tapping bases 44, and a laser emitter is fixedly connected to each rubber tapping base 44.

[0066] The working process of the rubber tapping mechanism 41 is as follows:

[0067] Before starting the rubber tapping operation, the equipment is in standby mode. The rubber tapping conveyor motor 432 stops running, and the rubber tapping conveyor belt 434 is stationary. The laser emitters on the two parallel and opposite rubber tapping seats 44 are also in the off state. The PCB board, which has undergone processes such as pin removal and flipping, is placed on the rubber tapping conveyor belt 434, ready for the rubber tapping operation.

[0068] The rubber tapping conveyor motor 432 operates, driving the rubber tapping conveyor pulley 433, which is fixedly connected to it, to rotate. Since the rubber tapping conveyor belt 434 is fixedly wound around the rubber tapping conveyor pulley 433, the rotation of the pulley 433 drives the rubber tapping conveyor belt 434 to move cyclically. At this time, the PCB board placed on the rubber tapping conveyor belt 434 begins to be conveyed forward as the belt moves, moving towards the laser emitter.

[0069] When the PCB board is conveyed to the effective cutting area of ​​the laser emitter, the laser emitter is activated. The two laser emitters on the two cutting mounts 44 simultaneously emit high-energy laser beams, which are focused onto the tape on the PCB board. The high energy of the laser causes the tape to melt or vaporize instantly, thus achieving the cutting of the tape.

[0070] During the continuous conveying of the PCB board by the tape-cutting conveyor belt 434, the laser emitter continuously emits laser light to continuously cut the tape on the PCB board. Because the tape-cutting seats 44 are arranged in parallel opposite directions, the two laser emitters can cut the tape on the PCB board from different angles, ensuring the integrity and accuracy of the cutting effect.

[0071] The rubber tapping rotation mechanism 42 is located on one side of the rubber tapping conveyor belt 434. The rubber tapping rotation mechanism 42 includes a rubber tapping rotation fixing frame 421, a rubber tapping rotation motor 422, a rubber tapping rotation shaft 423, and a rubber tapping rotation disk 424. The rubber tapping rotation fixing frame 421 is fixedly connected to the frame 1, and the rubber tapping rotation motor is fixedly connected to the rubber tapping rotation fixing frame 421. One end of the rubber tapping rotation shaft 423 is fixedly connected to the rubber tapping rotation motor 422, and the other end is fixedly connected to the rubber tapping rotation disk 424. The rubber tapping rotation mechanism 42 rotates the PCB board 90°, facilitating the rubber tapping mechanism 41 to cut the tape on the other two sides of the PCB.

[0072] The working process of the rubber tapping rotating mechanism 42 is as follows:

[0073] When the PCB board is conveyed to the appropriate position above the rubber tapping rotary table 424, the rubber tapping conveyor belt 434 stops moving, fixing the PCB board in that position and ensuring that the PCB board can accurately contact and rotate with the rubber tapping rotary table 424. The rubber tapping rotary motor 422 starts running, and its output shaft generates rotational power. Since one end of the rubber tapping rotary shaft 423 is fixedly connected to the output shaft of the rubber tapping rotary motor 422, and the other end is fixedly connected to the rubber tapping rotary table 424, the rotation of the rubber tapping rotary motor 422 is transmitted to the rubber tapping rotary table 424 through the rubber tapping rotary shaft 423, causing the rubber tapping rotary table 424 to begin rotating around the shaft.

[0074] The tape-cutting rotary disc 424 contacts the PCB board during rotation, causing the PCB board to rotate as well. The tape-cutting rotary motor 422 precisely controls the rotation angle according to a preset program. When the tape-cutting rotary disc 424 rotates the PCB board 90°, the tape-cutting rotary motor 422 stops rotating. At this point, the PCB board has completed a 90° flip, and the other two sides that were not previously cut are now in a position where the tape-cutting mechanism 41 can easily cut them. After the PCB board has rotated, the tape-cutting conveyor belt 434 restarts, transporting the rotated PCB board back to the cutting area of ​​the tape-cutting mechanism 41. The tape-cutting mechanism 41 then cuts the tape on the other two sides of the PCB board again.

[0075] In another embodiment of this utility model, such as Figures 9-10 As shown, the separation conveying mechanism 51 includes a separation conveying frame 511, a separation conveying motor 512, a separation conveying pulley 513, and a separation conveying belt 514. The separation conveying frame 511 is fixedly connected to the frame 1, the separation conveying motor 512 is fixedly connected to the separation conveying frame 511, the separation conveying pulley 513 is fixedly connected to the separation conveying motor 512, and the separation conveying belt 514 is fixedly wound around the separation conveying pulley 513 and is located below the first transport mechanism 52 and the second transport mechanism 53.

[0076] The working process of the separation and conveying mechanism 51 is as follows:

[0077] The separating conveyor motor 512 starts operating, converting electrical energy into mechanical energy to power the entire conveying process. Since the separating conveyor pulley 513 is fixedly connected to the output shaft of the separating conveyor motor 512, the rotation of the separating conveyor motor 512 directly drives the separating conveyor pulley 513 to rotate synchronously. The separating conveyor belt 514 is fixedly wound around the separating conveyor pulley 513. When the separating conveyor pulley 513 rotates, it drives the separating conveyor belt 514 to move in a cycle through friction. The PCB board placed on the separating conveyor belt 514 is conveyed forward as the belt moves. The separating conveyor belt 514 gradually conveys the PCB board from the starting end to the designated position below the first conveying mechanism 52 and the second conveying mechanism 53.

[0078] In another embodiment of this utility model, such as Figure 11 As shown, the first conveying mechanism 52 and the second conveying mechanism 53 are arranged in parallel opposite directions. The first conveying mechanism 52 includes a first fixed frame 521, a first adjusting component 522, a first lifting cylinder 523, a first lifting frame 524, and a first suction cup 525. The first fixed frame 521 is fixedly connected to the frame 1. The first adjusting component 522 is connected to the first fixed frame 521. The first lifting cylinder 523 is fixedly connected to the first lifting frame 524. Multiple first suction cups 525 are provided, and all of them are fixedly connected to the first lifting frame 524. The first adjustment assembly 522 includes a first guide rod 5221, a first guide block 5222, a first slide rail 5223, and a first slider. The first guide rod 5221 is fixedly connected to the bottom side of the first fixed frame 521. The first guide block 5222 is slidably connected to the first guide rod 5221. The first slide rail 5223 is fixedly connected to the bottom side of the first fixed frame 521 and is disposed on one side of the first guide rod 5221. The first slider is slidably connected to the first slide rail 5223. The first lifting cylinder 523 is fixedly connected to the first slider. The first slide rail 5223 is provided with a plurality of first limiting holes. After the first lifting frame 524 is adjusted in position by the first slider and the first slide rail 5223, the first lifting frame 524 is limited by inserting a positioning pin into the first limiting hole.

[0079] The working process of the first handling mechanism 52 is as follows:

[0080] Before the transport operation begins, the first transport mechanism 52 is in its initial state. The first lifting cylinder 523 is in its retracted state, positioning the first lifting frame 524 and the first suction cup 525 at a higher position to avoid interference with the separation conveying mechanism 51 and the PCB board below. The first slider and the first guide block 5222 of the first adjusting component 522 are in their preset positions, and the positioning pin is not inserted into the first limiting hole.

[0081] Depending on the location and size of the PCB board or copper plate to be transported, the position of the first lifting frame 524 needs to be fine-tuned. The operator manually pushes the first slider, causing it to slide on the first slide rail 5223. Simultaneously, the first guide block 5222 slides synchronously on the first guide rod 5221, ensuring smooth movement of the first lifting cylinder 523 and the first lifting frame 524. Once the first lifting frame 524 has moved to the appropriate position, the positioning pin is inserted into the corresponding first limit hole on the first slide rail 5223 to limit and fix the first lifting frame 524, ensuring its positional stability during transport.

[0082] After the separating conveying mechanism 51 transports the PCB board or copper plate to the designated position, the first lifting cylinder 523 is activated. The piston rod of the first lifting cylinder 523 extends, pushing the first lifting frame 524 downward. The multiple first suction cups 525 fixedly connected to the first lifting frame 524 descend accordingly until they contact the surface of the copper plate. At this time, the first suction cups 525 activate their adsorption function, tightly adsorbing the copper plate through vacuum adsorption or other methods.

[0083] After the first suction cup 525 successfully picks up the copper plate, once the copper plate is moved to the designated position, the first suction cup 525 closes its suction function, releases the picked-up copper plate, and the copper plate falls into the copper plate unloading box 536.

[0084] In another embodiment of this utility model, such as Figure 12 As shown, the second conveying mechanism 53 includes a second fixed frame 531, a second adjusting component 532, a second lifting cylinder 533, a second lifting frame 534, a second suction cup 535, and a copper plate unloading box 536. The second fixed frame 531 is fixedly connected to the frame 1, the second adjusting component 532 is connected to the second fixed frame 531, the second lifting cylinder 533 is fixedly connected to the second lifting frame 534, and multiple second suction cups 535 are provided, all of which are fixedly connected to the second lifting frame 534. The second adjustment assembly 532 includes a second guide rod 5321, a second guide block 5322, a second slide rail 5323, and a second slider. The second guide rod 5321 is fixedly connected to the bottom side of the second fixed frame 531. The second guide block 5322 is slidably connected to the second guide rod 5321. The second slide rail 5323 is fixedly connected to the bottom side of the second fixed frame 531 and is disposed on one side of the second guide rod 5321. The second slider is slidably connected to the second slide rail 5323. The second lifting cylinder 533 is fixedly connected to the second slider. The second slide rail 5323 is provided with multiple second limiting holes. After the second lifting frame 534 is adjusted in position by the second slider and the second slide rail 5323, the second lifting frame 534 is limited by inserting a positioning pin into the second limiting hole. Multiple copper plate unloading boxes 536 are provided and disposed below the first conveying mechanism 52 and the second conveying mechanism 53.

[0085] The working process of the second handling mechanism 53 is as follows:

[0086] Before the automatic PCB glue cutting machine is started, the second conveying mechanism 53 is in an initial standby state. The piston rod of the second lifting cylinder 533 retracts, so that the second lifting frame 534 and the multiple second suction cups 535 fixed thereon are in a higher position, avoiding collision with the equipment components below. The second slider and the second guide block 5322 in the second adjusting assembly 532 are in the initial preset position, and the positioning pin is not inserted into the second limit hole.

[0087] After the first conveying mechanism 52 absorbs and unloads the copper plate of the PCB board into the copper plate unloading box 536, the remaining pads of the PCB board are conveyed to the second conveying mechanism 53 by the separating conveying assembly, and then transferred to the pad unloading device 6 by the second conveying mechanism 53. The specific process is as follows:

[0088] Based on the specific dimensional requirements for separating the pads of the PCB board to be processed, the position of the second lifting frame 534 needs to be adjusted. The operator manually pushes the second slider, causing it to slide along the second slide rail 5323. Simultaneously, the second guide block 5322 slides synchronously on the second guide rod 5321, ensuring smooth movement of the second lifting cylinder 533 and the second lifting frame 534. A positioning pin is inserted into the corresponding second limit hole on the second slide rail 5323 to lock the position of the second lifting frame 534, preventing displacement during subsequent handling.

[0089] The second lifting cylinder 533 drives the second lifting frame 534 to move down, and the second suction cup 535 moves down synchronously and picks up the pad. Then the pad is placed on the separating conveyor belt 514, and the separating conveyor belt 514 transports the pad to the pad unloading device 6.

[0090] In another embodiment of this utility model, such as Figure 13 As shown, the feeding mechanism 62 includes a feeding roller 621, a feeding roller 622, a feeding shaft 623, a feeding roller 624, a feeding belt 625, and a feeding plate 626. The feeding roller 621 is rotatably connected to the feeding machine base 61, the feeding roller 622 is fixedly connected to the feeding roller 621, the feeding shaft 623 is rotatably connected to the feeding machine base 61, the feeding roller 624 is fixedly connected to the feeding shaft 623, and the feeding plate 626 is rotatably connected to the feeding machine base 61.

[0091] The working process of the feeding mechanism 62 is as follows:

[0092] The PCB board pad after copper plate separation is conveyed to the unloading machine 61 and reaches the working range of the unloading mechanism 62. At this time, the pad is located near the unloading roller 621 and the unloading turntable 626.

[0093] A drive device (such as a motor) is installed on the feed roller 621 to drive the feed roller 621 to start rotating. Since the feed roller 622 is fixedly connected to the feed roller 621, the rotation of the feed roller 621 drives the feed roller 622 to rotate synchronously. When the feed roller 622 contacts the pad, the friction between the roller and the pad is used to push the pad to move along the surface of the feed machine platform 61.

[0094] Meanwhile, a power unit is installed on the feeding shaft 623. Driven by the power unit (such as a motor), the feeding shaft 623 begins to rotate. The feeding wheel 624 is fixedly connected to the feeding shaft 623, and the rotation of the feeding shaft 623 causes the feeding wheel 624 to rotate accordingly. The rotation of the feeding wheel 624 coordinates with the movements of the feeding roller 621 and the feeding roller 622, further assisting in the transfer of the pad and ensuring that the pad can move smoothly and accurately towards the feeding plate 626.

[0095] The feeding belt 625 is wrapped around the feeding roller 624 and other components. As the feeding roller 624 rotates, the feeding belt 625 also begins to circulate. The part of the feeding belt 625 that contacts the pad provides continuous conveying power to the pad through friction, enhancing the conveying effect of the pad, preventing the pad from jamming or deviating during the conveying process, and ensuring that it smoothly reaches the position of the feeding plate 626.

[0096] When the pad moves to the unloading turntable 626, a drive device is installed on the unloading turntable 626, and the unloading turntable 626 begins to rotate under the action of the corresponding drive device (such as a cylinder). The unloading turntable 626 rotates at a certain angle, changing the angle between itself and the surface of the unloading machine table 61, so that the pad slides down along the inclined surface of the unloading turntable 626, thereby realizing the unloading of the pad from the unloading machine table 61 and completing the unloading operation.

[0097] The automatic PCB cutting machine of this application, through the sequentially arranged feeding device 2, PIN removal device 3, cutting device 4, copper plate separation device 5, and pad unloading device 6, realizes the fully automated operation of PCB board from feeding to completing cutting, copper plate separation, and pad unloading, which greatly improves production efficiency and reduces labor costs; the whole equipment has a compact structure, stable operation, and good market application prospects.

[0098] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
