Description

Technical Field

[0001] This utility model relates to the field of PCB separation equipment, and in particular to a fully automatic PCB separation machine. Background Technology

[0002] A PCB (Printed Circuit Board) is the carrier for the electrical connections of electronic components. In industry, to achieve mass production of PCBs, multiple PCBs are typically fabricated on a single board. A PCB depaneling machine usually refers to a PCB depaneling machine, also known as a circuit board depaneling machine. Depaneling machines are widely used in the electronics manufacturing industry. Because traditional manual PCB bending methods generate strong stress, severely impacting product quality, manual bending has been largely replaced by machine depaneling.

[0003] The common solution is to use a PCB depaneling machine to mill each PCB. To prevent the PCB from shifting or warping during milling and to ensure the quality of PCB processing, a conveyor line is used to transport the PCB to be milled to the positioning fixture. The positioning fixture is then used to position the PCB before milling. After milling, the PCB is output using a conveyor line. Therefore, the conveyor line is usually very long, which makes the PCB depaneling machine bulky and inconvenient to handle and arrange.

[0004] An existing patent (publication number: CN 108834316 A, publication date: 2018.11.16) discloses a fully automatic PCB depaneling machine. It employs a feeding and conveying mechanism arranged sequentially on the frame to input the PCB board from the previous station to the feeding station, a feeding mechanism to move the PCB board from the feeding station to the depaneling station, a depaneling mechanism, a depaneling mechanism to move the PCB board from the depaneling station to the unloading station, and a depaneling and conveying mechanism to output the processed PCB board. The two mechanisms work together to realize a fully automatic assembly line operation of the PCB board from alignment and conveying to feeding, depaneling and unloading. It has high work efficiency, good depaneling quality, high yield rate, high degree of automation and low labor cost.

[0005] In the above solution, the PCB boards are transported one by one to the bottom of the feeding mechanism through the feeding and conveying mechanism. The PCB boards are then fed into the separating mechanism through the feeding mechanism. However, the PCB boards are usually stacked together before the separating process. The above equipment needs to place the PCB boards to be separated one by one onto the feeding and conveying mechanism by mechanical automation or manual operation. Mechanical automation of PCB board placement will result in a large machine, while manual placement has problems such as low accuracy, slow efficiency and high labor costs.

[0006] In addition, the common solution at present is to use a PCB depaneling machine to mill each PCB. In order to prevent the PCB from shifting or warping during milling and to ensure the processing quality of the PCB, the PCB to be milled is transported to the positioning fixture by a conveyor line during processing. The positioning fixture is then used to position the PCB before milling. After milling, the PCB is output by a conveyor line.

[0007] For example, an existing patent (publication number: CN117381877A, publication date: 2024.01.12) discloses a PCB board slitting and splitting machine. Under the squeezing action of the top plate and the limiting pulley, the PCB board can be fixed above the material conveying plate. After the motor starts, the reciprocating screw can drive the material conveying plate to move back and forth along the slide rail, so as to achieve more precise and automated cutting of the PCB board.

[0008] The above solution can only cut one line at a time. For products with multiple PCBs fabricated on one board, the cutting efficiency is very low. Although the traditional manual board bending method is more efficient, it will affect the quality of the product. Therefore, it is necessary to design a mechanically automated board bending device that can bend multiple PCBs on the same board at once. Since mechanical equipment has advantages such as high precision and no static electricity, it is more efficient than manual board bending and will not affect the quality of the PCBs. There is no such device in the current technology, and this technical problem cannot be solved. Utility Model Content

The slide table is fixedly installed on the first slider of the two Y-axis conveying mechanisms.

[0017] Furthermore: four transverse sliding grooves are formed on the front placement platform, two transverse rods are fixedly installed on the bottom side of the front placement platform, and second sliders are slidably installed on the transverse rods. A connecting plate is fixedly installed between two adjacent second sliders. A second belt conveyor is fixedly installed on the bottom side of the front placement platform.

Vertical rods are fixedly installed on the second sliders, and the vertical rods are slidably installed in the transverse sliding grooves one by one.

[0018] Furthermore: the plate feeding mechanism includes a base, several third belt conveyors, a second servo motor, and a second drive shaft. The base is lifted and slidably mounted on the worktable. The several third belt conveyors are all fixedly mounted on the base. The second servo motor is mounted on the worktable. The second servo motor drives the several third belt conveyors to operate synchronously through the second drive shaft. The adaptive plate picking mechanism transports the plate material on the placement table to the several third belt conveyors of the plate feeding mechanism.

[0019] Furthermore: the PCB separator module includes a positioning base plate, a lead screw conveying mechanism, a roller assembly, two side limiting plates, multiple first blades, and multiple second blades; the lead screw conveying mechanism is fixedly installed on the positioning base plate, and drives the roller assembly to move back and forth; the two side limiting plates are respectively fixedly installed on the left and right ends of the upper side of the positioning base plate, and the lead screw conveying mechanism is located between the two side limiting plates; the two side limiting plates are symmetrically arranged to each other, and a limiting strip is fixedly installed on the top edge of the outer side of the side limiting plate; the two ends of the bottom sides of the multiple first blades and multiple second blades are respectively snapped onto the limiting strips of the two side limiting plates; when the roller assembly moves, it drives the first blades and second blades to be lifted upwards.

[0020] Furthermore: the third belt conveyor is arranged one-to-one between the two PCB splitting machine modules, and a lifting unit is provided on the bottom side of the base. The lifting unit is fixedly installed in the frame and drives the plate feeding mechanism to move up and down.

The high-elastic material is fixedly installed on the bottom side of the lifting platform. The lifting platform presses against the multiple PCB separation machine modules through the high-elastic material.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The adaptive adsorption machine picks up the PCB board material to be separated on the front placement table, then uses the Y-axis conveyor to transport it to the board feeding mechanism, and finally uses the board feeding mechanism to send it into the board separating station of the separating machine for automatic board separation operation.

[0025] 2. The adaptive adsorption machine can adapt to PCB boards of different thicknesses for feeding and conveying, which facilitates the automated operation of the depaneling equipment. The board will be conveyed to the top of the depaneling machine module, and the board will be pressed on the depaneling machine module by the pressing mechanism to realize the automated depaneling action.

[0026] 3. During board separation, a high-elasticity material is used to press down the top side of the board. At this time, the bottom surface of the board will press down on multiple first blades and multiple second blades. The board separation line on the board is parallel to the first blades and second blades. Then, the lead screw conveyor mechanism is activated, which drives the roller group to move back and forth. When the roller group moves back and forth, it will lift up the first blades and second blades at the corresponding positions. When lifting up several first blades and second blades, the pressing with the high-elasticity material above will simulate a repeated manual board folding action, allowing multiple PCB boards on the board to separate from each other, thus achieving a fast board separation action.

[0027] This invention eliminates the need for manual board separation, avoiding defective boards, and also offers high board separation efficiency.

[0049] like Figure 1-13 As shown, the present invention provides a fully automatic PCB depaneling machine, which includes a frame 1 on which a worktable 2 is fixedly installed.

[0050] The workbench 2 is equipped with a feeding device, a PCB separator module and a pressing mechanism 23;

[0051] The feeding device includes a plate feeding mechanism 3, a front placement platform 4, and an adaptive plate picking mechanism 6. The plate feeding mechanism 3 is fixedly installed on the workbench 2, the front placement platform 4 is fixedly installed on the front side of the frame 1, and the plate material 5 to be separated is stacked on the front placement platform 4. The adaptive plate picking mechanism 6 is installed at the front end of the workbench 2 and the adaptive plate picking mechanism 6 transports the plate material 5 on the placement platform to the plate feeding mechanism 3.

[0052] The PCB splitting machine module is provided with multiple partitioned components. The PCB splitting machine module is fixedly installed on the workbench 2. The board feeding mechanism 3 conveys the board material 5 to the PCB splitting machine module. The pressing mechanism 23 is fixedly installed on the upper end of the frame 1. The pressing mechanism 23 is located above the PCB splitting machine module and presses the board material 5 onto the PCB splitting machine module.

[0053] The adaptive plate-taking mechanism 6 includes a Y-axis conveying mechanism 61, a slide table 62, and an adaptive adsorption machine 63. The Y-axis conveying mechanism 61 drives the slide table 62 to slide above the front placement platform 4 and the plate-feeding mechanism 3. The adaptive adsorption machine 63 is installed on the slide table 62.

[0054] The principle is as follows: The adaptive adsorption machine 63 picks up the PCB board material 5 to be processed on the front placement table 4, and then uses the Y-axis conveyor to transport it to the board feeding mechanism 3. Finally, the board feeding mechanism 3 sends it into the board separating station of the separating machine for automatic board separating operation, realizing automated board separating. The adaptive adsorption machine 63 can adapt to the feeding and conveying of PCB board materials 5 with different stacking thicknesses, which is convenient for the automated operation of the separating equipment. The board material 5 will be transported to the top of the separating machine module. By pressing down the pressing mechanism 23, the board material 5 is pressed on the separating machine module to realize the automatic board separating action, which is convenient and fast, without the need for manual board separating, avoiding the occurrence of board material defects, and the board separating efficiency is high.

[0055] Furthermore: The adaptive adsorption machine 63 includes a top plate 631, a lifting cylinder 632, a crossbar 633, and a plurality of lifting rods 634. The top plate 631 is located above the slide table 62. Support rods 7 are fixedly installed at all four ends of the bottom side of the top plate 631. The bottom ends of the support rods 7 are fixedly installed on the slide table 62. The lifting cylinder 632 is fixedly installed on the top plate 631. The telescopic rod of the lifting cylinder 632 passes through the top plate 631 and drives the crossbar 633 to move up and down. A plurality of guide sleeves 8 are fixedly installed on the slide plate. The plurality of lifting rods 634 are slidably installed in the plurality of guide sleeves 8. A top connecting rod 9 is fixedly installed at the upper end of two adjacent lifting rods 634. The top connecting rod 9 is located above the crossbar 633. A suction cup assembly 10 is fixedly installed at the lower end of the lifting rod 634.

[0056] The principle is as follows: When the lifting cylinder 632 drives the crossbar 633 to descend, the lifting rod 634 will descend with its own weight. When the suction cup assembly 10 at the lower end of the lifting rod 634 falls onto the stacked board material 5 on the front placement platform 4, the suction cup assembly 10 will adsorb the top layer of board material 5 by vacuuming. Then, the lifting cylinder 632 drives the crossbar 633 to rise. When the crossbar 633 rises to a certain position, it will lift the lifting rod 634 through the top connecting rod 9, thereby lifting the top layer of board material 5. Since the lifting cylinder 632 does not directly drive the lifting rod 634 to move up and down, the lifting rod 634 descends by its own weight. Therefore, it can be applied to board material 5 with different stacking thicknesses to achieve adaptive board picking operation. Finally, the Y-axis conveying mechanism 61 is used to transport it to the top of the board feeding mechanism 3, and the board material 5 is placed on the board feeding mechanism 3 by breaking the vacuum.

[0057] Each suction cup assembly 10 of the adaptive adsorption machine 63 descends independently using its own gravity, enabling it to adapt to PCB materials of different stacking thicknesses and uneven heights.

[0058] Furthermore: at least two vertical rods 25 are fixedly installed between the slide table 62 and the top plate 631, and at least two second guide sleeves 26 are fixedly installed on the horizontal rod 633. The vertical rods 25 are slidably installed in the second guide sleeves 26 in a one-to-one correspondence; this allows the horizontal rod 633 to play a stable lifting and sliding role.

[0059] Furthermore: the suction cup assembly 10 includes a bottom connecting rod 101, two suction cup adjusting rods 102, two suction cup bolts 103, and two positioning suction cups 104. The bottom connecting rod 101 is fixedly installed at the bottom end of two adjacent lifting rods 634. The bottom connecting rod 101 is located below the slide table 62. The two suction cup adjusting rods 102 are both fixedly installed on the bottom side of the bottom connecting rod 101. The suction cup bolts 103 are fixedly installed on the suction cup adjusting rods 102 one by one. The positioning suction cups 104 are fixedly installed at the bottom end of the suction cup bolts 103.

[0060] The principle is that the bottom connecting rod 101 can enhance the stability between two adjacent lifting rods 634, ensuring that the lifting rod 634 can be raised and lowered stably on the guide sleeve 8 of the slide table 62. The angle and position of the suction cup bolt 103 can be adjusted by the suction cup adjustment rod 102 at the bottom, so that it can be used for plates 5 of different widths.

[0061] Furthermore: a transverse groove 11 is formed in the middle of the suction cup adjusting rod 102, and a first positioning bolt 22 is installed in the transverse groove 11. The suction cup adjusting rod 102 is locked to the bottom side of the bottom connecting rod 101 by passing through the transverse groove 11 with the first positioning bolt 22. Before locking, the first positioning bolt 22 can slide in the transverse groove 11, thereby adjusting its locking position, which facilitates adjusting the position of the suction cup bolt 103.

[0062] Furthermore, two Y-axis conveying mechanisms 61 are provided. Each Y-axis conveying mechanism 61 includes a side frame 611, a first belt conveyor 612, and a first slider 613. The side plate 3251 is fixedly installed on the worktable 2. The side plates 3251 of the two Y-axis conveying mechanisms 61 are symmetrically arranged to each other. The first slider 613 is slidably mounted on the side frame 611. The first belt conveyor 612 is fixedly mounted on the side frame 611 and drives the first slider 613 to move back and forth. The slide table 62 is fixedly mounted on the first slider 613 of the two Y-axis conveying mechanisms 61. After the top plate 5 is removed from the front placement table 4, the plate 5 can be moved above the plate feeding mechanism 3 by driving the slide table 62 through the first belt conveyors 612 on both sides, which improves the stability of the conveying.

[0063] Furthermore: a first servo motor 12 is fixedly installed on the side frame 611 of one of the Y-axis conveying mechanisms 61, and a first drive shaft 13 is connected between the first belt conveyors 612 of the two Y-axis conveying mechanisms 61. The first servo motor 12 drives the two first belt conveyors 612 to operate synchronously through the first drive shaft 13. The first drive shaft 13 can be used to make the first belt conveyors 612 on both sides operate synchronously, thereby ensuring the stability of conveying the sheet material 5.

[0064] Furthermore: the front placement platform 4 has four transverse sliding grooves 14 formed on it. Two transverse rods 15 are fixedly installed on the bottom side of the front placement platform 4. Second sliders 16 are slidably installed on the transverse rods 15. A connecting plate 17 is fixedly installed between two adjacent second sliders 16. A second belt conveyor 18 is fixedly installed on the bottom side of the front placement platform 4. The second belt conveyor 18 drives the second sliders 16 on the left and right sides to move left and right on the transverse rods 15. Vertical rods 19 are fixedly installed on the second sliders 16. The vertical rods 19 are slidably installed in the transverse sliding grooves 14. This can be used for adaptive plate length positioning adjustment. Since the vertical rods 19 are fixedly fixed on the second sliders 16, and the second sliders 16 can also be driven by the second belt conveyor 18, when one of the vertical rods 19 moves, it can drive the other three vertical rods 19 to move together, thereby driving the vertical rods 19 on both sides to clamp the plate 5. The second belt conveyor 18 can be used for automatic width adaptation adjustment, which is convenient for processing plates 5 of different widths.

[0065] Furthermore, the plate feeding mechanism 3 includes a base 31, several third belt conveyors 32, a second servo motor 33, and a second drive shaft 34. The base 31 is slidably mounted on the worktable 2. The several third belt conveyors 32 are all fixedly mounted on the base 31. The second servo motor 33 is mounted on the worktable 2. The second servo motor 33 drives the several third belt conveyors 32 to operate synchronously through the second drive shaft 34. The adaptive plate picking mechanism 6 transports the plate material 5 on the placement table to the several third belt conveyors 32 of the plate feeding mechanism 3. The several third belt conveyors 32 can simultaneously support the plate material 5 for transport. The setting of the second drive shaft 34 enables the several third belt conveyors 32 to operate synchronously, thereby achieving stable transport of the plate material 5.

[0066] Furthermore: The third belt conveyor 32 is arranged one-to-one between the two PCB splitting machine modules. A lifting unit 24 is provided on the bottom side of the base 31. The lifting unit 24 is fixedly installed in the frame 1. The lifting unit 24 drives the board feeding mechanism 3 to move up and down; so that the third belt conveyor 32 can drive the board material 5 to be transported to the PCB splitting machine module, realizing automated board splitting and loading.

[0067] Furthermore, the third belt conveyor 32 includes a positioning frame 321, a drive pulley 322, a driven pulley 323, a transmission belt 324, and two tensioning mechanisms 325. The positioning frame 321 is fixedly mounted on the base 31. The two tensioning mechanisms 325 are fixedly mounted one-to-one at the front and rear ends of the positioning frame 321. The drive pulley 322 and the driven pulley 323 are rotatably fitted into the two tensioning mechanisms 325. The transmission belt 324 is fitted between the drive pulley 322 and the driven pulley 323. The second drive shaft 34 is threaded and mounted on the drive pulleys 322 of several third belt conveyors 322. The second drive shaft 34 drives several drive pulleys 322 to rotate synchronously. The transmission belt 324 can be tensioned by the tensioning mechanisms 325 at the front and rear ends, so that it can be stably fitted between the drive pulleys 322 and the driven pulleys 323, thereby ensuring the stable transmission of the sheet material 5 on several third belt conveyors 32.

[0068] Furthermore, the second servo motor 33 is fixedly installed between the positioning frames 321 of two adjacent second belt conveyors 32.

[0069] Furthermore: The tensioning mechanism 325 includes two side plates 3251, two second positioning bolts 3252, two adjusting bolts 3253, and two positioning blocks 3254. The front and rear ends of the positioning frame 321 are each formed with two sliding adjustment grooves 20. The positioning frame 321 is disposed between the two side plates 3251. The side plates 3251 and the positioning frame 321 are locked together by the second positioning bolts 3252 passing through the sliding adjustment grooves 20. The positioning blocks 3254 are fixedly installed on the positioning frame 321. The positioning blocks 3254 are formed with threaded holes 21. The adjusting bolts 3253 are screwed into the threaded holes 21. One end of the adjusting bolts 3253 is set to press against the side plates 3251.

[0070] The principle is as follows: A sliding adjustment groove 20 is set on the positioning frame 321, and the second positioning bolt 3252 can slide in the sliding adjustment groove 20, thereby allowing the transmission belt 324 to be tightly fitted between the driving pulley 322 and the driven pulley 323. The second positioning bolt 3252 is used to lock the side plate 3251 for positioning. The adjusting bolt 3253 is screwed into the threaded hole 21 of the positioning block 3254. At the same time, one end of the adjusting bolt 3253 presses against the side plate 3251 to lock the position of the transmission belt 324 after tensioning, ensuring that the transmission belt 324 will not loosen on its own. When it is necessary to replace the transmission belt 324, it can also be de-tensioned by loosening the adjusting bolt 3253 and the second positioning bolt 3252, thus facilitating the replacement of the transmission belt 324.

[0071] Furthermore: the PCB separator module includes a positioning base plate 01, a lead screw conveying mechanism 02, a roller assembly 03, two side limiting plates 04, multiple first blades 05, and multiple second blades 06; the lead screw conveying mechanism 02 is fixedly installed on the positioning base plate 01, and the lead screw conveying mechanism 02 drives the roller assembly 03 to move back and forth; the two side limiting plates 04 are respectively fixedly installed on the left and right ends of the upper side of the positioning base plate 01, and the lead screw conveying mechanism 02 is located between the two side limiting plates 04; the two side limiting plates 04 are symmetrically arranged to each other, and a limiting strip 07 is fixedly installed on the top edge of the outer side of the side limiting plate 04; the two ends of the bottom sides of the multiple first blades 05 and the multiple second blades 06 are respectively snapped onto the limiting strips 07 of the two side limiting plates 04; when the roller assembly 03 moves, it drives the first blades 05 and the second blades 06 to be lifted upwards;

[0072] The principle is as follows: The sheet metal to be separated is conveyed piece by piece by a conveyor and placed above the separating machine module. A high-elasticity material 022 is then used to press down on the top and side of the sheet metal. At this time, the bottom surface of the sheet metal will press against multiple first blades 05 and multiple second blades 06. The separating lines on the sheet metal are parallel to the first blades 05 and second blades 06. Then, the screw conveyor mechanism 02 is activated, driving the roller assembly 03 to move back and forth. As the roller assembly 03 moves back and forth, it lifts the corresponding first blades 05 and second blades 06. After lifting several first blades... When the blade 05 and the second blade 06 are pressed against the upper high-elastic material 022, a repeated manual folding action is simulated, allowing multiple PCBs on the board to be separated from each other, achieving rapid board separation. Even if there are multiple PCBs on the board, the separation can be completed in one go. Compared with the traditional cutting method, the separation efficiency of this utility model is higher. Moreover, the separation is carried out by mechanical equipment, which can ensure the force and angle when folding each PCB, and at the same time, no static electricity is generated, which can ensure the quality of the PCB after rapid folding.

[0073] Furthermore: the first blade 05 has first barbs 08 formed at both ends of its bottom side, and the second blade 06 has second barbs 09 formed at both ends of its bottom side. The outer side of the limiting strip 07 has protrusions 010 arranged in an equidistant array. The first barbs 08 are snapped onto the protrusions 010, and the second barbs 09 are snapped onto the limiting strip 07. The protrusions 010 provide precise positioning for multiple stacked first blades 05 and multiple stacked second blades 06, allowing them to rise or fall stably. The top sides of the first blades 05 and the second blades 06 have no cutting edges, so they can effectively lift the board material 5, thereby simulating the action of bending the board. As the roller group 03 moves back and forth, even if the board material 5 contains multiple PCB boards, it can be quickly separated.

[0074] Furthermore: the thickness of the limiting strip 07 is the same as the thickness of the protrusion 010, and the width of the first barb 08 and the second barb 09 is greater than the thickness of the limiting strip 07; this makes the installation of the first blade 05 and the second blade 06 more stable and secure, ensuring that the first blade 05 and the second blade 06 will not tilt when they move up and down, thereby ensuring the quality of the plate separation.

[0075] In this utility model, the main function of the limiting strip 07 and the first blade 05 and second blade 06 is to segment and separate the blades. Because a certain gap must be left between adjacent blades, the first blade 05 and the second blade 06 can slide smoothly up and down. If they are not segmented, it is difficult to control the gap between adjacent blades. If the gap is large, the blade will fall to one side. If the gap is small, the friction between the blades will increase, resulting in the blades not moving smoothly up and down. Furthermore, as the blades continue to rub against each other, wear will occur, and the gap will increase with the use time. The increased gap will cause the blade gaps to accumulate and stack together, causing the blades to fall to one side. Therefore, it is necessary to continuously add blades to fill the gaps to ensure that the blades do not fall over. This application uses the segmented separating protrusion 010 to effectively control the blade gaps and prevent the accumulated gaps between the blades from becoming too large. This can both widen the gaps between the blades and ensure smooth up and down movement of the blades. It can also solve the problem of blade wear causing the blade gaps to increase and the need for more blades.

[0076] Furthermore, the side limiting plate 04 is provided with a height adjustment edge 011 on its outer side. The height adjustment edge 011 is located below the limiting strip 07. The top side of the height adjustment edge 011 is set to abut against both ends of the first blade 05 and the second blade 06. The lifting stroke of the first blade 05 and the second blade 06 can be controlled by adjusting the height adjustment edge 011. This allows for adaptability settings based on the thickness of the board material 5, thereby preventing damage to the PCB board during bending and ensuring the production quality of the PCB board.

[0077] Furthermore: Two positioning posts 012 are fixedly installed on the outer side of the side limiting plate 04. Vertical threads 013 are formed on the positioning posts 012. A screw 014 is screwed into the vertical threads 013. The upper end of the screw 014 abuts against the height adjustment edge 011. The lower end of the screw 014 is formed with an internal hexagonal groove 015. The installation height of the height adjustment edge 011 can be controlled by twisting the screw 014, thereby controlling the lifting stroke of the first blade 05 and the second blade 06.

[0078] Furthermore, at least two vertical adjustment grooves 016 are formed on the height adjustment edge 011, and locking bolts 017 are installed in the vertical adjustment grooves 016 with clearance fit. The locking bolts 017 pass through the vertical adjustment grooves 016 and lock onto the side limiting plate 04. The locking bolts 017 can pass through the vertical adjustment grooves 016 to secure the height adjustment edge 011 to the side limiting plate 04, thereby ensuring the stable installation of the height adjustment edge 011.

[0079] Furthermore: the lead screw conveying mechanism 02 includes a drive motor 0201, a coupling 0202, a lead screw shaft 0203, and a lead screw drive block 0204. A motor base 023 is fixedly installed on the positioning base plate 01, and the drive motor 0201 is fixedly installed on the motor base 023. Lead screw support seats 024 are rotatably fitted at both ends of the lead screw shaft 0203, and the lead screw support seats 024 are fixedly installed on the positioning base plate 01. The drive motor 0201 drives the lead screw shaft 0203 to rotate through the coupling 0202. The lead screw drive block 0204 is screw-fitted onto the lead screw shaft 0203, and the roller assembly 03 is fixedly installed on the lead screw drive block 0204. The roller assembly 03 can be controlled to move back and forth by the drive of the lead screw motor, resulting in high stability.

[0080] Furthermore: The roller assembly 03 includes a sliding platform 0301 and two roller supports 0302. The sliding platform 0301 is fixedly mounted on the lead screw drive block 0204. The two roller supports 0302 are respectively fixedly mounted on the left and right ends of the upper side of the sliding platform 0301. The two roller supports 0302 are symmetrically arranged to each other. Several support rollers 0303 arranged in an equidistant array are rotatably installed inside the roller supports 0302. When the support rollers 0303 move, they press against the first blade 05 and the second blade 06 at the corresponding positions. When the roller assembly 03 slides once, the first blade 05 and the second blade 06 can be lifted by the several support rollers 0303 on both sides, thereby lifting the corresponding blades and simulating the action of folding plates. The arrangement of several support rollers 0303 can lift the first blade 05 and the second blade 06 multiple times, thereby realizing the action of rapid plate separation.

[0081] Furthermore: two guide rails 018 are fixedly installed on the positioning base plate 01, and two sliding blocks 019 are slidably installed on each guide rail 018. The sliding platform 0301 is fixedly installed above the four sliding blocks 019, making the forward and backward movement of the sliding platform 0301 more stable.

[0082] Furthermore: A first side cover 025 is fixedly installed on the outer side of the height adjustment edge 011, and the first blade 05 and the second blade 06 are both fitted with a clearance between the first side covers 025 on the left and right sides; the setting of the first side cover 025 can ensure that the first blade 05 and the second blade 06 will not tilt left or right, thereby ensuring their stable lifting and lowering.

[0083] Furthermore: Two limiting top edges 020 are fixedly installed between the two side limiting plates 04. Multiple first blades 05 and multiple second blades 06 are fitted together between the two limiting top edges 020. Second side covers 021 are fixedly installed on both the front and rear sides of the two side limiting plates 04. The roller assembly 03 moves back and forth between the two second side covers 021. The setting of the limiting top edges 020 can ensure the stable installation of the first blades 05 and the second blades 06, and can ensure that the first blades 05 and the second blades 06 will not tilt back and forth, so that they can move up and down stably. The second side covers 021 can provide a covering and protection function to ensure the service life of the depaneling machine module.

[0084] Furthermore: the pressing mechanism 23 includes a pneumatic cylinder 231, a lifting platform 232, and a high-elastic material 022. The pneumatic cylinder 231 is fixedly installed on the top side of the frame 1. The telescopic rod of the pneumatic cylinder 231 drives the lifting platform 232 to move up and down. The lifting platform 232 is located above multiple PCB separation machine modules. The high-elastic material 022 is fixedly installed on the bottom side of the lifting platform 232. The high-elastic material 022 can be made of pearl cotton. The lifting platform 232 presses against the multiple PCB separation machine modules through the high-elastic material 022. During plate operation, the pneumatic rod 231 drives the lifting platform 232 to press down. The lifting platform 232 presses the plate material 5 on the plate separating machine module with the high elastic material 022. At this time, the lifting unit 24 drives the plate feeding mechanism 3 to move to the bottom side, so that the third belt conveyor 32 is lower than the upper edge of the first cutter 05 and the second cutter 06. At this time, the plate material 5 will be pressed on the first cutter 05 and the second cutter 06. The plate material 5 is broken along the plate separating line by the back and forth sliding of the roller group 03, thereby realizing the action of rapid plate separating.
