[0045] like Figure 1-Figure 12 As shown, the plate stack positioning device 100 according to the embodiment of the present invention includes: a workbench 1, a positioning and clamping assembly lifting and positioning assembly 5 and a spindle module 6.

[0046] The workbench 1 has a positioning area, and the positioning area is used to carry the PCB board 400. The PCB board 400 can be positioned and aligned in the positioning area so that the PCB board 400 is in a target state, which is conducive to continuing the subsequent drilling and milling operations. In the specific design, the workbench 1 can be constructed as a rectangular table, and the positioning area is formed in the middle of the workbench 1, so that the PCB board 400 is positioned in the middle of the workbench 1.

[0047] The positioning and clamping assembly is installed on the workbench 1. The positioning and clamping assembly is used to drive the PCB board 400 to be positioned in the first direction and / or the second direction, and has a first clamping member 43 for clamping the PCB board 400. For example, in some specific embodiments, the positioning and clamping assembly may include a first pin position 21, a first push clamping assembly 41, a second pin position 22, and a second push clamping assembly 42. The first push clamping assembly 41 and the first pin position 21 are relatively distributed on both sides of the positioning area along the first direction. Figure 3 As shown, the workbench 1 is constructed as a rectangular table, and the first pin position 21 and the first push and clamp assembly 41 are Figure 3 The distribution is from the upper left to the lower right, that is, Figure 3 The direction from the upper left to the lower right in the figure is the first direction, and the workbench 1 is set horizontally when it is actually working. The first direction can be set to the direction of the X-axis of the PCB drilling equipment 1000. The first pin position 21 and the first pushing and clamping component 41 are spaced apart and distributed on the workbench 1 in the X-direction, and the positioning area is located between the first pin position 21 and the first pushing and clamping component 41.

[0048] The first pin support position 21 includes a first pin support plate 211 and a first pin 212. The first pin 212 is installed on the first pin support plate 211. Figure 3 As shown, the first pin plate 211 is located at one side edge of the workbench 1X direction, and a first pin hole 212 open upward is provided on the first pin plate 211, and the first pin 212 is installed in the first pin hole 212 and protrudes upward. The first pushing and pressing assembly 41 is located at the other side edge of the workbench 1X direction.

[0049] The workbench 1 is provided with an adjustable clamping mechanism 3 on the side of the first pin plate 211. The adjustable clamping mechanism 3 can perform a clamping operation on the PCB board 400, and the position of the adjustable clamping mechanism 3 along the X direction on the workbench 1 is adjustable so that the adjustable clamping mechanism 3 can clamp PCB boards 400 of different specifications and at different positions.

[0050] The second pushing and pressing assembly 42 and the second pin-receiving position 22 are arranged on both sides of the positioning area along the second direction. Figure 3 As shown, the workbench 1 is constructed as a rectangular table, and the second pin position 22 and the second pushing and pressing assembly 42 are in Figure 3The distribution is from the lower left to the upper right, that is, Figure 3 The direction from the lower left to the upper right in the figure is the second direction, and the workbench 1 is set horizontally when it is actually working. The second direction can be set to the direction of the Y axis of the PCB drilling equipment 1000. The second pin position 22 and the second pushing and clamping assembly 42 are spaced apart and distributed on the workbench 1 in the Y direction, and the positioning area is also located between the second pin position 22 and the second pushing and clamping assembly 42.

[0051] The second pin support position 22 includes a second pin support plate 221 and a second pin 222. The second pin 222 is mounted on the second pin support plate 221. Figure 3 As shown, the second pin plate 221 is located at one side edge of the workbench 1Y direction, and a second pin hole 222 open upward is provided on the second pin plate 221, and the second pin 222 is installed in the second pin hole 222 and protrudes upward. The second pushing and pressing assembly 42 is located at the other side edge of the workbench 1Y direction.

[0052] Wherein, the first pushing and pressing assembly 41 and the second pushing and pressing assembly 42 both include a first pressing member 43. It should be noted that the first pressing member 43 of the first pushing and pressing assembly 41 can move along the first direction, that is, the first pressing member 43 can move toward the first abutting pin 212, so as to push the PCB board 400 toward the first abutting pin 212 and press it during the movement, so as to adjust the position of the PCB board 400 along the first direction, and the first pressing member 43 can press the PCB board 400. Similarly, the first pressing member 43 of the second pushing and pressing assembly 42 can move along the second direction, that is, the first pressing member 43 can move toward the second abutting pin 222, so as to push the PCB board 400 toward the second abutting pin 222 and press it during the movement, so as to adjust the position of the PCB board 400 along the second direction, and the first pressing member 43 can press the PCB board 400. Thus, the position of the PCB board 400 can be adjusted by the first pushing and pressing assembly 41 and the second pushing and pressing assembly 42, and the positioning and pressing of the PCB board 400 can be achieved. The first pressing member 43 can be constructed to include a first rod body portion 431 and a first pressing plate 432, the first rod body portion 431 is used to push the PCB board 400 to move, and the first pressing plate 432 is used to press the PCB board 400.

[0053] The lifting and positioning assembly 5 can be lifted and lowered on the workbench 1, and is provided with a positioning pin 55 located in the positioning area. It should be noted that the lifting and positioning assembly 5 is located in the positioning area and can be lifted and lowered in the positioning area. During actual positioning, the PCB board 400 is placed above the lifting and positioning assembly 5. In this way, when the lifting and positioning assembly 5 moves upward relative to the workbench 1, the positioning pin 55 can be extended into the positioning hole 401 of the PCB board 400 to achieve positioning and matching.

[0054] The spindle module 6 is movable relative to the workbench 1, and the spindle module 6 is used to clamp the pin 62. Fig.11 As shown, the spindle module 6 includes a spindle and a presser foot 61 disposed at the end of the spindle, a clamping hole is disposed in the middle of the presser foot 61, and a pin 62 can be clamped in the clamping hole. The pin 62 is detachable in the clamping hole. A knife inspection module 71 and a knife disc module 72 are disposed on one side of the workbench 1, and a plurality of pins 62 are placed in the knife disc module 72.

[0055] By using the stacked board positioning device 100 of the present invention, when positioning the PCB board 400, the PCB board 400 is placed in the positioning area, and the first pressing member 43 of the first pushing and pressing assembly 41 and the first pressing member 43 of the second pushing and pressing assembly 42 respectively push the PCB board 400 from different directions, so that the PCB board 400 is pressed and contacted with the first supporting pin 212 in the X direction, and at the same time, the PCB board 400 is pressed and contacted with the second supporting pin 222 in the Y direction, thereby achieving rough positioning of the PCB board 400. Furthermore, a pin 62 is clamped on the spindle module 6, and the spindle module 6 moves downward so that the pin 62 extends into the positioning hole 401, so that the PCB board 400 is positioned and calibrated by the pin 62, and after the positioning and calibration, the pin 62 is removed, and the spindle module 6 is controlled to press the PCB board 400 downward, and at the same time, the lifting component is controlled to push upward so that the positioning pin 55 on the lifting component enters into the positioning hole 401 of the PCB board 400, realizing the positioning process and completing the upper PIN operation, and finally, the PCB board 400 is pressed by the first pushing and clamping component 41, the second pushing and clamping component 42 and the adjustable clamping mechanism 3 to realize the positioning operation.

[0056] According to the stacked plate positioning device 100 of the embodiment of the present invention, the stacked plate positioning device 100 can realize automatic positioning and pressing of the PCB board 400 after the operator places the PCB board 400 into the positioning area. The positioning process is accurate and reliable, and the PIN is automatically withdrawn after processing. The manual operation process is relatively simple, and only the PCB board 400 needs to be placed. The operation difficulty is low, which is conducive to improving the processing efficiency.

[0057] In some embodiments, there are two first pushing and clamping components 41, two adjustable clamping mechanisms 3, and two lifting and positioning components 5. Figure 3 As shown in the figure, the two first pushing and clamping components 41 are located at the lower edge of the workbench 1 and are spaced apart along the Y direction; the two adjustable clamping mechanisms 3 are located at the upper edge of the workbench 1 and are respectively arranged at the two ends of the first pin position 21 in the Y direction; and the two lifting and positioning components 5 are sequentially distributed in the positioning area along the second direction, and the lifting and positioning components 5 are located in the middle position of the workbench 1 in the up and down direction, and are spaced apart along the Y direction.

[0058] Among them, a first pushing and clamping component 41, a lifting and positioning component 5 and an adjustable clamping mechanism 3 are arranged opposite to each other in the first direction, and another first pushing and clamping component 41, another lifting and positioning component 5 and another adjustable clamping mechanism 3 are arranged opposite to each other in the first direction. Figure 3 As shown, a group of first pushing and clamping components 41, lifting and positioning components 5 and adjustable clamping mechanism 3 are formed in the left area of ​​the workbench 1. At the same time, a group of first pushing and clamping components 41, lifting and positioning components 5 and adjustable clamping mechanism 3 are formed in the right area of ​​the workbench 1, so that the left area and the right area of ​​the PCB board 400 can be positioned respectively, which is beneficial to improve the positioning reliability and positioning accuracy of the PCB board 400.

[0059] In some embodiments, Figure 8 As shown, the adjustable pressing mechanism 3 includes a first mounting seat 31 , a first movable member 32 and a second pressing member 34 .

[0060] Among them, the first mounting seat 31 is installed on the workbench 1, such as the first mounting seat 31 is fixedly connected to the workbench 1, or is detachably connected through a connecting piece, the first movable member 32 is movably installed on the first mounting seat 31 along the first direction, and the second clamping member 34 is movably installed on the first movable member 32 along the vertical direction, that is, the first movable member 32 can slide along the X direction relative to the first mounting seat 31, so that when the first movable member 32 moves relative to the workbench 1, the second clamping member 34 can move along the X direction relative to the workbench 1 and the PCB board 400. In this way, when the second clamping member 34 moves along the X direction, the PCB board 400 can be pushed to make the PCB board 400 move toward the first support pin 212.

[0061] The second clamping member 34 is movable vertically relative to the first movable member 32, that is, the second clamping member 34 can be raised and lowered relative to the first movable member 32. In other words, the second clamping member 34 can be raised and lowered relative to the workbench 1 and the PCB board 400 carried on the workbench 1, thereby facilitating the clamping effect on the PCB board 400 and achieving the positioning of the PCB board 400.

[0062] The second pressing member 34 may be constructed to include a second rod portion 341 and a second pressing plate 342. The second rod portion 341 is connected to the output end of the driving cylinder so that the driving cylinder can drive the second rod portion 341 to rise and fall. The second pressing plate 342 is connected to the upper end of the second rod portion 341. When the second pressing plate 342 slides relative to the first mounting seat 31, the second rod portion 341 pushes the PCB board 400. When the second pressing member 34 rises and falls relative to the first movable member 32, the second pressing plate 342 presses the PCB board 400.

[0063] In some embodiments, the first movable member 32 includes a first sliding portion 322, a first matching tooth portion 323 and an elastic member 33, wherein the first sliding portion 322 and the first matching tooth portion 323 are both mounted on the movable member body 321 of the first movable member 32, so that the first sliding portion 322 and the second matching tooth portion 313 are relatively fixed through the movable member body 321. The first mounting seat 31 includes a second sliding portion 312 and a second matching tooth portion 313, the second sliding portion 312 and the second matching tooth portion 313 are mounted on the mounting seat body of the first mounting seat 31, and the second sliding portion 312 and the second matching tooth portion 313 are relatively fixed through the mounting seat body.

[0064] Among them, the second sliding part 312 is slidably matched with the first sliding part 322. In actual design, the first sliding part 322 can be constructed as a sliding block, and the second sliding part 312 can be constructed as a sliding guide rail arranged on the upper surface of the mounting seat body 311, and the sliding block is installed on the sliding guide rail so that the sliding block can slide relative to the sliding guide rail. Specifically, the sliding guide rail is extended along the X direction so that the first sliding part 322 can move along the X direction relative to the sliding guide rail, and then drive the second clamping member 34 to move along the X direction during the sliding process, thereby realizing the pushing effect on the PCB board 400.

[0065] The first mating tooth portion 323 and the second mating tooth portion 313 are meshed. Figure 8 As shown, the first mating tooth portion 323 includes a mounting rod 324 and a movable rack 325, the movable rack 325 is connected to the lower end of the mounting rod 324, and the lower surface of the movable rack 325 is formed with meshing teeth, the mounting rod 324 is passed through the movable part body 321, so that the mounting rod 324 can move relative to the movable part body 321; at the same time, the second mating tooth portion 313 is constructed as a meshing rack arranged on the upper surface of the mounting seat body, and the upper surface of the meshing rack is provided with meshing teeth, so that the meshing rack can mesh with the movable rack 325.

[0066] The elastic member 33 is used to apply an elastic force to the first mating tooth portion 323 to press the second mating tooth portion 313. Figure 8 As shown, the elastic member 33 is constructed as a spring, which is sleeved outside the mounting rod 324 , and the lower end of the spring presses against the upper surface of the movable rack 325 , and the upper end of the spring presses against the movable member body 321 .

[0067] Among them, in actual use, the elastic member 33 can apply a driving force toward the movable rack 325 to press the movable rack 325 against the meshing rack to achieve meshing and fixation. When driving the first movable member 32 to move along the X direction relative to the first mounting seat 31, the elastic force of the elastic member 33 can be overcome to make the movable rack 325 move relative to the meshing rack. After the position of the first movable member 32 is adjusted, it is locked in other positions again by the elastic force of the elastic member 33 to achieve relative fixation of the first movable member 32 and the first mounting seat 31.

[0068] In some embodiments, the lifting and positioning assembly 5 includes a lifting plate 51, a second mounting seat 52 and a first driving member 53. The second mounting seat 52 is relatively fixed to the workbench 1, the lifting plate 51 is movably mounted on the second mounting seat 52 in the vertical direction, and the first driving member 53 is used to drive the lifting plate 51 to move. In other words, the second mounting seat 52 is fixed relative to the workbench 1, and the lifting plate 51 is vertically movable relative to the second mounting seat 52. The first driving member 53 can drive the lifting plate 51 to rise and fall relative to the second mounting seat 52 and the workbench 1, and the positioning pin 55 is provided on the lifting plate 51.

[0069] During actual installation, the PCB board 400 is installed above the lifting plate 51 so that the lifting plate 51 can drive the positioning pin 55 to move relative to the PCB board 400 during the lifting process, so that the positioning pin 55 can be inserted into the positioning hole 401 of the PCB board 400.

[0070] It should be noted that if Figure 3 As shown, a lifting and positioning assembly 5 is provided in the left and right areas of the workbench 1, respectively. Figure 4 and Figure 5 As shown, the structure of the lifting and positioning assembly 5 located in the left area is different from that of the lifting and positioning assembly 5 located in the right area. Figure 4 The lifting and positioning assembly 5 is shown in the right area, wherein the lifting plate 51 is guided and matched with the second mounting seat 52 through three guide rods 54. At the same time, two first driving members 53 are provided at the bottom of the second mounting seat 52, so that the two first driving members 53 can simultaneously lift and lower the lifting plate 51, ensuring that the lifting plate 51 is lifted and lowered smoothly. Figure 5 The figure shows a lifting and positioning assembly 5 located in the left area, wherein a lifting plate 51 is guided and matched with a second mounting seat 52 through two guide rods 54. Meanwhile, a first driving member 53 is provided at the bottom of the second mounting seat 52 so that the first driving member 53 can drive the lifting plate 51 to lift and lower.

[0071] Optionally, the first driving member 53 may be configured as a driving cylinder.

[0072] In some embodiments, the first pushing and clamping assembly 41 and the second pushing and clamping assembly 42 both further include a third mounting seat 44, a second movable member 45 and a second driving member 46. In other words, in actual construction, the first pushing and clamping assembly 41 and the second pushing and clamping assembly 42 can be set to the same structure, and the first clamping member 43 of the first pushing and clamping assembly 41 moves along the X direction, and the first clamping member 43 of the second pushing and clamping assembly 42 moves along the Y direction.

[0073] Among them, Figure 6 As shown, the second movable member 45 is slidably mounted on the third mounting seat 44. Specifically, the third mounting seat 44 includes two guide seats 441. Both guide seats 441 are provided with support rails 442. Matching grooves are provided on both sides of the second movable member 45. The matching grooves are slidably matched with the support rails 442, so that both sides of the second movable member 45 are slidably supported on the two guide seats 441. The second driving member 46 is used to drive the second movable member 45 to move, that is, when the position of the PCB board 400 is adjusted, the second driving member 46 can be controlled to output a driving force so that the second movable member 45 slides relative to the third mounting seat 44. Optionally, the second driving member 46 can be a driving cylinder.

[0074] The first pressing member 43 is installed on the second movable member 45 in a liftable manner. Therefore, the first pressing member 43 can move with the second movable member 45, so that the first pressing member 43 moves relative to the workbench 1, thereby pressing and positioning the PCB board 400, and when pressing the PCB board 400, the first pressing member 43 can be driven to rise and fall relative to the third mounting seat 44 and the workbench 1, thereby achieving positioning and pressing of the PCB board 400.

[0075] like Figure 6 As shown, the first pressing member 43 may be constructed to include a first rod body portion 431 and a first pressing plate 432. The first rod body portion 431 is connected to the output end of the driving cylinder so that the driving cylinder can drive the first rod body portion 431 to rise and fall. The first pressing plate 432 is connected to the upper end of the first rod body. When the first pressing member 43 slides relative to the third mounting seat 44, the first rod body portion 431 pushes the PCB board 400. When the first pressing member 43 rises and falls relative to the second movable member 45, the first pressing plate 432 presses the PCB board 400.

[0076] In some embodiments, the first direction and the second direction are perpendicular to each other and are both perpendicular to the vertical direction. For example, one of the first direction and the second direction is along the X-axis direction of the workbench 1, and the other of the first direction and the second direction is along the Y-axis direction of the workbench 1, so that the stack positioning device 100 can position the PCB board 400 in the horizontal plane and achieve compression in the Z direction.

[0077] Among them, the stacked plate positioning device 100 in the embodiment of the present invention can be applied to the PCB drilling equipment 1000. After the operator places the PCB board 400 into the positioning area, the stacked plate positioning device 100 can realize automatic positioning and pressing of the PCB board 400. The positioning process is accurate and reliable, and the PIN is automatically withdrawn after processing. The manual operation process is relatively simple, and only the PCB board 400 needs to be placed. The operation difficulty is low, which is conducive to improving the processing efficiency.

[0078] Among them, Figure 1 As shown, the PCB drilling device 1000 further includes a base assembly 200, and a plurality of stacked plate positioning devices 100 are provided above the base assembly 200. Specifically, a mounting crossbeam 300 is provided above the base assembly 200, and the spindle modules 6 of the plurality of stacked plate positioning devices 100 are installed on the mounting crossbeam 300 at intervals, and the work tables 1 of the plurality of stacked plate positioning devices 100 are installed on the base assembly 200, so that the plurality of stacked plate positioning devices 100 can simultaneously realize positioning processing of the plurality of PCB boards 400, which is conducive to improving processing efficiency.

[0079] The invention also provides a stacked plate positioning method.

[0080] The stacked plate positioning method according to an embodiment of the present invention is applicable to the stacked plate positioning device described in any of the above embodiments. The stacked plate positioning method includes:

[0081] S10: placing the PCB board in the positioning area, specifically, making the PCB board be located above the lifting positioning assembly, and in the X direction, the PCB board is located between the first pin position and the first pushing and pressing assembly, and in the Y direction, the PCB board is located between the second pin position and the second pushing and pressing assembly.

[0082] S20: Control the positioning and clamping assembly to roughly position the PCB board. Specifically, the PCB board can be clamped in the X direction by the first pushing and clamping assembly and the first pin position of the positioning and clamping assembly to achieve rough positioning of the PCB board in the X direction, and the PCB board can be clamped in the Y direction by the second pushing and clamping assembly and the second pin position of the positioning and clamping assembly to achieve rough positioning of the PCB board in the Y direction.

[0083] S30: Control the spindle module to perform secondary calibration and positioning of the PCB board, and the spindle module cooperates with the lifting and positioning assembly to perform a pin-up operation on the PCB board, so that the PCB board can be further positioned and calibrated in the horizontal plane, so that the positioning pin and the positioning hole are more accurately aligned.

[0084] S40: Control the first pressing member and the second pressing member to press the PCB board, such as the first pressing members of the first pushing and pressing assembly and the first pressing members of the second pushing and pressing assembly both press the upper surface of the PCB board, and at the same time, the second clamping member of the adjustable pressing mechanism also presses the upper surface of the PCB board, thereby increasing the positioning accuracy and stability of the PCB board.

[0085] In some embodiments, step S30 of controlling the spindle module to perform secondary calibration and positioning of the PCB board and cooperating with the lifting and positioning assembly to perform a PIN operation on the PCB board includes:

[0086] S31: Control the spindle module to extend the pin into a positioning hole of the PCB board for positioning. Specifically, the spindle module clamps the pin and can move the spindle module along the mounting beam to above the positioning hole on the left side of the PCB board, and extend the pin downward so that the pin extends into the positioning hole, so that the PCB board moves under the calibration action of the pin, thereby realizing the positioning calibration of the left area of ​​the PCB board.

[0087] S32: Control the presser foot of the spindle module to press against a positioning hole of the PCB board, and control the positioning pin of a lifting and positioning assembly to pass through a positioning hole. Specifically, after completing the positioning calibration of the left area of ​​the PCB board, control the spindle module to rise, remove the pin, and then control the spindle module to move above the left positioning hole of the PCB board, control the spindle module to descend, so that the presser foot presses against the edge of the left positioning hole of the PCB board, presses down the left area of ​​the PCB board, and at the same time controls the lifting plate of a lifting and positioning assembly located on the left side to rise, so that the positioning pin on the lifting plate extends upward into the positioning hole, and as the presser foot is pressed down, the positioning pin can effectively penetrate into the positioning hole.

[0088] S33: Control the spindle module to extend the pin into another positioning hole of the PCB board for positioning. Specifically, the spindle module clamps the pin and can move the spindle module along the mounting beam to above the positioning hole on the right side of the PCB board, and extend the pin downward so that the pin extends into the positioning hole, so that the PCB board moves under the calibration action of the pin, thereby realizing the positioning calibration of the right side area of ​​the PCB board.

[0089] S34: Control the presser foot of the spindle module to press against another positioning hole of the PCB board, and control the positioning pin of another lifting and positioning assembly to pass through another positioning hole. Specifically, after completing the positioning calibration of the right area of ​​the PCB board, control the spindle module to rise, remove the pin, and then control the spindle module to move above the right positioning hole of the PCB board, control the spindle module to descend, so that the presser foot presses against the edge of the right positioning hole of the PCB board, presses down the left area of ​​the PCB board, and at the same time controls the lifting plate of a lifting and positioning assembly located on the right side to rise, so that the positioning pin on the lifting plate extends upward into the positioning hole, and as the presser foot is pressed down, the positioning pin can effectively penetrate into the positioning hole.

[0090] Thereby, the positioning calibration of the two side areas of the PCB board and the deep fixation of the positioning pins are achieved.

[0091] In some embodiments, the stacked board positioning method further includes S01: obtaining parameters of positioning holes of the PCB board before placing the PCB board in the positioning area to determine positions of the positioning holes on the PCB board.

[0092] S02: Processing the positioning pin hole on the lifting and positioning assembly, processing the first pin hole on the first pin plate of the positioning and clamping assembly, and processing the second pin hole on the second pin plate of the positioning and clamping assembly according to the parameters. Specifically, the program can be used to control the spindle to move to the top of the first pin plate to process the first pin hole on the first pin plate, or control the spindle to move to the top of the lifting plate to process the positioning pin hole on the first pin plate, and move to the top of the second pin plate to process the second pin hole on the second pin plate.

[0093] S03: Place the positioning pin in the positioning pin hole, place the first supporting pin in the first supporting pin hole, and place the second supporting pin in the second supporting pin hole. Specifically, extend the positioning pin from the top of the lifting plate into the positioning pin hole, place the first supporting pin into the first supporting pin hole from the top of the first supporting pin plate, and place the second supporting pin into the second supporting pin hole from the top of the second supporting pin plate.

[0094] In some embodiments, S20 controlling the first pushing and clamping assembly and the second pushing and clamping assembly to roughly position the PCB board includes:

[0095] S21 controls the first pushing member of the positioning and clamping assembly to push the PCB board along the first direction toward the first support pin. Specifically, the second movable member of the first pushing and clamping assembly is controlled to move along the X direction relative to the third mounting seat, so that the first clamping member moves toward the first support pin, and pushes the PCB board toward the first support pin during the movement, thereby realizing the positioning of the PCB board in the X direction.

[0096] S22 controls the second pushing member of the positioning and clamping assembly to push the PCB board along the second direction toward the second support pin. Specifically, the second movable member of the second pushing and clamping assembly is controlled to move along the Y direction relative to the third mounting seat, so that the first clamping member moves toward the second support pin, and pushes the PCB board toward the second support pin during the movement, thereby realizing the positioning of the PCB board in the Y direction.

[0097] The following describes some specific embodiments of the stack positioning method of the present invention, including a preparation stage, a positioning stage and a pressing stage.

[0098] During the preparation stage: according to the parameters of the positioning holes of the PCB board of corresponding specifications, the spindle module is controlled by the program to process the positioning pin holes on the positioning plates of the two lifting and positioning components, the first supporting pin holes on the first supporting pin plate, and the second supporting pin holes on the second supporting pin plate.

[0099] Further, a positioning hole is installed in the positioning pin hole, and a first supporting pin and a second supporting pin are installed in the first supporting pin hole and the second supporting pin hole respectively.

[0100] Then, the PCB board is placed on the workbench so that one side edge of the PCB board is close to the first support pin and one side edge of the PCB board is close to the second support pin.

[0101] During the positioning stage: preliminary calibration and positioning, control the first pushing and clamping assembly to push the PCB board toward the first support pin so that the PCB board and the first support pin are against each other, and control the second pushing and clamping assembly to push the PCB board toward the second support pin so that the PCB board and the second support pin are against each other.

[0102] Perform secondary positioning and calibration on the area on one side of the PCB board. The spindle module or the manipulator can drive the pin to descend so that the pin enters the positioning hole on the left side of the PCB board. After positioning is completed, the spindle module or the manipulator is controlled to lift and pull out the pin. Then, pin the area on one side of the PCB board, control the spindle module to move to a certain position, and then descend again. Fix the surrounding of the positioning hole on the left side of the PCB board by the pressure foot on the spindle, and control the lifting plate under the left side of the PCB board to lift, so that the positioning pin on the lifting plate moves upward and extends into the positioning hole on the left side of the PCB board to complete the pinning action.

[0103] Perform secondary positioning and calibration on the area on the other side of the PCB board. The spindle module or the manipulator can drive the pin to descend so that the pin enters the positioning hole on the right side of the PCB board. After positioning is completed, the spindle module or the manipulator is controlled to lift and pull out the pin; then pin the area on the other side of the PCB board, control the spindle module to move to a certain position, and then descend again, and fix the surrounding of the positioning hole on the right side of the PCB board by the pressure foot on the spindle, and control the lifting plate under the right side of the PCB board to lift, so that the positioning pin on the lifting plate moves upward and extends into the positioning hole on the right side of the PCB board, completing the pin-up action.

[0104] During the clamping stage, the first clamping members of the first pushing and clamping assembly and the second pushing and clamping assembly both move downward, and at the same time, the second clamping member of the adjustable clamping mechanism moves downward to clamp and fix the PCB board on the workbench to complete the precise positioning of the multiple stacked boards.

[0105] The stacked plate positioning method according to the embodiment of the present invention has the following advantages:

[0106] 1) Two positioning pins for cooperating with the PCB board are respectively implanted into the lifting plates of the two lifting and positioning components. There is no need to perform a separate PIN operation on the PCB board. Compared with the PIN clamp processing method, it saves users the cost of purchasing other equipment and has the processing accuracy of the bakelite board.

[0107] 2) Two positioning pins for cooperating with the PCB board are respectively implanted into the lifting plates of the two lifting and positioning components. After processing, the PINs can be automatically withdrawn, which saves time and realizes automation compared with the bakelite processing method.

[0108] 3) By using the edge of the PCB board to abut against the first and second support pins, the initial positioning process is simple and convenient.

[0109] 4) Using the pins installed on the spindle module to perform secondary calibration and positioning of the multi-layer PCB board is more conducive to the insertion of the two positioning pins and reduces damage to the PCB board. It is understandable that: since the initial positioning is edge positioning, there is an error in the size of the two positioning holes of the PCB from the two sides of the PCB board. If the pins are directly inserted, the PCB board will be damaged and the pin insertion action will fail.

[0110] It should be noted that the pin used in the present invention for secondary calibration positioning has a head diameter of φd and a main shaft diameter of φD, and satisfies: φd<φD1<φD. Fig.12 As shown, the meaning of φD1 is: multiple PCB boards are positioned side by side, and the position deviation of the positioning holes of each PCB board is such that a pin with a diameter of φD1 can pass through smoothly.

[0111] This allows accurate positioning of multiple stacks of plates.
