[0028] like Figure 1 , Figure 2 As shown, the circuit board processing equipment of this utility model includes: a base, a crossbeam, processing sections, a worktable, etc. The worktable is disposed on the base and moves along a second direction. Multiple processing sections that move along a first direction are slidably mounted on the crossbeam above the worktable. Each processing section includes at least two spindle assemblies, and the spindle of each spindle assembly moves along a third direction to process the circuit board carried on the worktable. At least two spindle assemblies of each processing section synchronously replicate the same circuit board carried on the worktable to improve processing efficiency. The first direction, the second direction, and the third direction are perpendicular to each other. In the context of this utility model, the circuit board processing equipment can be implemented as a drilling device, a forming device, a milling machine, a drilling and milling integrated device, etc., and is not limited thereto. In the above and below embodiments of this utility model, the number of spindle assemblies of the circuit board processing equipment can be six, twelve, eighteen, etc., and is not limited thereto.

[0029] In multi-spindle circuit board machining, the various spindle assemblies sliding on the crossbeam move relative to the worktable to determine the machining position. However, due to factors such as assembly, thermal expansion and contraction, wear, and vibration, the actual position of the spindle assembly deviates from its theoretical position, affecting the machining accuracy. Therefore, circuit board machining equipment needs to fine-tune the actual position of each spindle assembly to improve both machining efficiency and the synchronous replication accuracy of each spindle.

[0030] This invention provides a circuit board processing device, comprising: a crossbeam, on which multiple processing sections are slidably connected along a first direction, each processing section including a first spindle assembly and a second spindle assembly; multiple first spindle assemblies connected in series and moving synchronously along the first direction, each second spindle assembly moving independently along both the first and second directions, the second direction being perpendicular to the first direction; and the first and second spindle assemblies synchronously copying and processing the same circuit board carried on a worktable. This circuit board processing device can improve processing efficiency while precisely adjusting the position of each spindle assembly, thereby improving the accuracy of multi-axis synchronous copying processing.

[0031] Specifically, along a first direction on the crossbeam, multiple first spindle assemblies and multiple second spindle assemblies are arranged at intervals, with the number of first and second spindle assemblies being the same. An adjacent first spindle assembly and a second spindle assembly constitute a processing unit, and each processing unit synchronously replicates the same circuit board carried on the worktable. Multiple first spindle assemblies are connected in series via connecting rods extending along the first direction. A first driving component drives the multiple first spindle assemblies and connecting rods to move synchronously along the first direction. In the upper and lower embodiments of this invention, the series connection via connecting rods means that multiple first spindle assemblies are fixedly connected to the same connecting rod, and the connecting rod drives the multiple first spindle assemblies to move synchronously along the first direction. Each second spindle assembly slides independently along the first direction on the crossbeam. Each second spindle assembly is also provided with an adjustment part, which can independently drive the second spindle to move along a second direction. This configuration of spindle assemblies allows for precise adjustment of the position of each spindle assembly, improving the accuracy of multi-axis synchronous replication processing.

[0032] In some embodiments of this invention, a plurality of pneumatic clamping assemblies corresponding to processing units are provided on the worktable. The first spindle assembly is aligned with the detection body held by the pneumatic clamping assembly to determine the position of the first spindle assembly. Specifically, the worktable carrying the circuit board is located below the spindle assembly. Pneumatic clamping assemblies are provided on the worktable, with each pneumatic clamping assembly corresponding to a processing unit. That is, each pneumatic clamping assembly positions a circuit board on the worktable, and the first and second spindle assemblies simultaneously replicate and process the circuit board. The pneumatic clamping assembly holds the detection body, which extends towards the spindle in a third direction. The first spindle assembly holds the detection body, which extends towards the pneumatic clamping assembly in a third direction. When the first spindle assembly and the detection body held by the pneumatic clamping assembly are aligned in the third direction, and both meet a preset concentricity threshold range, the position of the first spindle assembly can be determined. This method of detecting the position of the first spindle assembly using pneumatic clamping assemblies has high detection accuracy, low cost, and can effectively improve the positioning accuracy of the first spindle assembly.

[0033] In some embodiments of this invention, the first spindle assembly clamps the detection element, which rotates along the outer peripheral sidewall of the detection body to detect the concentricity of the first spindle assembly and the detection body. The detection body clamped by the pneumatic clamp assembly is a cylindrical structure. The first spindle assembly clamps the detection element against the outer peripheral sidewall of the detection body and rotates along the outer peripheral sidewall. Based on the detection result of the detection element, the concentricity of the detection body between the first spindle assembly and the pneumatic clamp assembly can be determined. The detection element rotates one revolution around the outer peripheral sidewall of the detection body, and the alignment position of the spindle assembly and the detection element is determined through at least three points. The deviation of the alignment position is used to determine whether the two meet the concentricity threshold range. In some preferred embodiments of this invention, the detection element is preferably a dial indicator, and the detection body is preferably a pin or a standard bar.

[0034] In some embodiments of this invention, multiple first spindle assemblies include a target spindle assembly and an object spindle assembly. First, the position of the target spindle assembly is determined, and then the pneumatic clamp assembly is controlled to move the detection body to align with the object spindle assembly, thereby determining the position of the object spindle assembly. For multiple first spindle assemblies, there is one target spindle assembly and at least one object spindle assembly connected in series by linkages. The position of at least one object spindle assembly is determined with the target spindle assembly as a reference. Therefore, it is necessary to first determine the position of the target spindle assembly. Using the detection body held by the pneumatic clamp assembly on the worktable as a reference, the target spindle assembly is controlled to rotate around the detection body, thereby determining the position of the target spindle assembly. After determining the position of the target spindle assembly, since at least one object spindle assembly is connected to the target spindle assembly via linkages, the position of the object spindle assembly is determined through the target spindle assembly. Specifically, after determining the position of the target spindle assembly, the pneumatic clamp assembly is controlled to move the detection body to align with the object spindle assembly. Using the object spindle assembly as a reference, the detection part is controlled to rotate around the detection body. After the pneumatic clamping assembly corresponding to the machining unit clamps the detection body and aligns it with the object spindle assembly, the position of the object spindle assembly is determined. It should be noted that, for the target spindle assembly, the position of the target spindle assembly is determined by controlling its movement to align with the detection body of the corresponding pneumatic clamping assembly, using the position of the object spindle assembly as a reference. For the object spindle assembly, the position of the object spindle assembly is determined by controlling the movement of the detection body of the pneumatic clamping assembly to align with the object spindle assembly, using the position of the object spindle assembly as a reference. It should be noted that the object spindle assembly and the target spindle assembly belong to different machining units, each corresponding to its own pneumatic clamping assembly. In this way, the position of the object spindle assembly can be fine-tuned, and even with connected linkages, the positions of multiple first spindle assemblies can be fine-tuned, thereby improving positioning and machining accuracy.

[0035] In multi-spindle circuit board processing equipment, each second spindle assembly can move independently along a first direction on the crossbeam. In the first direction, the positions of multiple second spindle assemblies can be precisely adjusted in real time. That is, the center coordinates of multiple second spindle assemblies in the first direction can be arbitrarily adjusted, and their relative positions can also be adjusted. However, in the second direction, because the worktable carries multiple circuit boards as a whole and moves along the second direction, the positions in the second direction cannot be adjusted independently. Furthermore, the relative errors between each second spindle assembly caused by assembly errors, vibration, wear, thermal expansion and contraction, etc., cannot be adjusted or compensated. To adjust the relative position of each second spindle assembly in the second direction, it is necessary to adjust the position of each second spindle in the second direction individually.

[0036] In some embodiments of this utility model, each second spindle assembly includes an adjustment part and a second spindle; the corresponding second spindle assembly is controlled to move along a first direction, and the corresponding adjustment part is controlled to adjust the position of the second spindle in a second direction to determine the position of the second spindle assembly.

[0037] Multiple second spindle assemblies are arranged at intervals along a first direction on a crossbeam. In a machining section, the position of the second spindle assemblies is adjusted with reference to the first spindle assembly. Specifically, the second spindle assembly includes an adjustment section and a second spindle. The adjustment section can be implemented as a manual adjustment component or an automatic adjustment component. The automatic adjustment component can include a ramp slide rail with a drive member, which drives a slider to slide on the ramp, thereby automatically adjusting the position of the second spindle in the second direction. The manual adjustment component can be implemented as an active component with a locking component. After the locking component is unlocked, the active component applies a pressure force in a specific direction to the second spindle, causing the second spindle to move slightly in a predetermined direction under the pressure force. Whether it is a manual or automatic adjustment component, the adjustment section can be controlled to adjust the position of the second spindle in the second direction with reference to the first spindle assembly. In the first direction, with reference to the position of the first spindle assembly, the second drive member drives the corresponding second spindle assembly to move along the first direction on the crossbeam. The movement of the second spindle assembly in the first and second directions determines the position of the second spindle assembly.

[0038] In some embodiments of this utility model, the first spindle assembly and the second spindle assembly are moved sequentially to any one of the following positions corresponding to the machining part to detect the relative positional deviation of the second spindle assembly. The various positions include: (1) the detection body held by the pneumatic clamp assembly; (2) the tool detection assembly on the worktable; and (3) the tool setter on the worktable. Specifically, the worktable is respectively provided with a pneumatic clamp assembly, a tool detection assembly, and a tool setter corresponding to the machining part. By controlling the first spindle assembly and the second spindle assembly to move sequentially to any one of the above-mentioned positions, the relative positional deviation of the first spindle assembly and the second spindle assembly can be detected. After the positional deviation is detected, the position of the second spindle is adjusted by the second drive member and the adjustment part until the deviation is reduced to a preset threshold range. That is, the first spindle assembly is first moved to the detection body of the pneumatic clamp assembly to determine the position of the first spindle assembly, and then the second spindle assembly is moved to the same detection body of the pneumatic clamp assembly. When the two spindle assemblies move to the same position, the relative positional deviation of the two spindle assemblies can be calculated. Once the relative positional deviation between the first and second spindle assemblies is determined, the second drive is controlled to move the second spindle assembly in the first direction to reduce or even eliminate the positional deviation in that direction. The adjustment unit is then controlled to drive the second spindle to make minor movements in the second direction to further reduce or eliminate the positional deviation. Similarly, a tool detection assembly or tool setter can be used to replace the detection body of the pneumatic chuck assembly. By controlling the first and second spindle assemblies to move sequentially to the same tool detection assembly or tool setter, their relative positional deviation can be detected, allowing for the elimination of the deviation and determination of the second spindle assembly's position. It should be noted that both the tool detection assembly and the tool setter are detection devices mounted on the worktable. Each machining section is equipped with one tool detection assembly or tool setter, and both can detect the position in the first and second directions respectively.

[0039] In some embodiments of this utility model, each first spindle assembly and second spindle assembly includes a base plate, with a back plate fixedly connected to one side and a crossbeam slidably connected to the other side of the back plate. Both the first and second spindle assemblies include a base plate, and the spindle, spindle clamp, sliding assembly, adjustment part, drive component, etc., are directly or indirectly integrated onto the base plate, which serves as a carrier for functional components. The first and second spindle assemblies are slidably connected to the crossbeam along a first direction via the back plate. Specifically, the base plate is fixedly connected to the back plate, and the back plate is slidably connected to the crossbeam. That is, the first spindle assembly is slidably connected to the crossbeam via the back plate, and the second spindle assembly is slidably connected to the crossbeam via the back plate. Multiple first and second spindle assemblies are linearly arranged at intervals along the first direction on the crossbeam.

[0040] In some embodiments of this utility model, a back plate is fixedly connected to a slider, the slider is slidably connected to a slide rail on a crossbeam, and there is a gap between the back plate and the slider, which is used to adjust the perpendicularity of the first spindle assembly and the second spindle assembly. The back plate is slidably connected to the crossbeam, a slider is provided on the back plate, a slide rail is provided on the crossbeam, the slider is fixedly connected to the back plate, the slider is slidably connected to the slide rail, and the slide rail is fixedly connected to the crossbeam. Simultaneously, there is a gap between the back plate and the slider, which can be achieved by providing an inclined surface on the back plate and / or the slider. When at least one side of the back plate or the slider is provided with an inclined surface extending along a third direction, a gap exists between the back plate and the slider. Since the gap extends along a third direction, adding a shim in the gap allows for fine adjustment of the perpendicularity of the first and second spindles along the third direction. In some preferred embodiments, the shim can be a metal component.

[0041] In some embodiments of this invention, a second driving member is provided on the back plate of the second spindle assembly near the crossbeam. Each second driving member drives the corresponding second spindle assembly and back plate to move along a first direction on the crossbeam. In each processing section, the second spindle assembly is provided with a second driving member, each second driving member corresponding one-to-one with the second spindle assembly. The second driving member drives the corresponding second spindle assembly and back plate to move along the first direction on the crossbeam to adjust the position of the second spindle assembly. The second driving member is integrated on the back plate, near the crossbeam. On the back plate, the slider and the second driving member are located on the same side of the back plate. In a third direction, the second driving member is located between two sliders; the second spindle assembly is located on the other side of the back plate. This structural design of the back plate can transfer and connect the base plate, rigidly connect multiple components, is stable and reliable, and saves space.

[0042] In some embodiments of this utility model, a connecting rod connects the back plates of multiple first spindle assemblies in series, and a first driving member drives the multiple first spindle assemblies, connecting rods, and base plates to move synchronously along a first direction on a crossbeam. In multiple processing units, multiple first spindle assemblies are arranged at intervals along the first direction on a crossbeam. The connecting rod connects the back plates of multiple first spindle assemblies in series, that is, multiple first spindle assemblies are connected in series on the same connecting rod through back plates, and each back plate and connecting rod are directly fixedly connected. The multiple first spindle assemblies connected in series by the connecting rod move synchronously as a whole along the first direction. Specifically, the circuit board processing equipment also includes a first driving member, which drives the multiple first spindle assemblies, connecting rods, and multiple back plates to move synchronously along the first direction on a crossbeam. In the first direction, the first driving member is located in the middle region of the connecting rod to stably and synchronously drive the multiple first spindle assemblies, connecting rods, and multiple back plates to move synchronously along the first direction, ensuring the balance and stability of the connecting rod. In the third direction, the first drive unit is located in the area between the two sliders, which can also ensure the stability and balance of the first drive unit driving multiple first spindle assemblies, connecting rods, and multiple back plates to move along the first direction on the crossbeam.

[0043] In the above and below embodiments of this utility model, when the perpendicularity of the spindle assembly is within a preset range, the position of the spindle assembly is determined using its center coordinates on the worktable. Specifically, the center coordinates of the spindle assembly can be detected and determined by detecting the relative position of the tool tip of the tool clamped at the bottom of the spindle assembly and the worktable, which can be done using a tool setter or tool inspection assembly. Simultaneously, when the actual center coordinates of the spindle assembly are not within the preset range of the theoretical center coordinates, the worktable and the spindle assembly move relative to each other, changing the center position of all spindle assemblies in the second direction; a single spindle assembly slides along the first direction on the crossbeam, changing the center coordinates of the single spindle assembly in the first direction, thus adjusting the center coordinates of the spindle assembly. When multiple spindle assemblies simultaneously replicate the same circuit board, the position of the first spindle assembly is first determined, and then, using the first spindle assembly as a reference, the positions of the second spindle assembly in the first and second directions are finely adjusted to determine the position of the second spindle assembly. This improves the accuracy of synchronous replication processing.

[0044] In the above and below embodiments of this utility model, the position of the spindle is adjusted, or the center position of the spindle is fine-tuned. This adjustment or fine-tuning refers to making precise adjustments based on the deviation between the actual center position and the theoretical center position. The adjustment range is typically at the micrometer or millimeter level. Due to the high assembly and processing precision of circuit board processing equipment, the actual deviation that needs adjustment may be 20 micrometers, 10 micrometers, or even a few micrometers. Precise positioning and fine-tuning of the positions of each spindle component can effectively improve processing accuracy.

[0045] Example 1

[0046] This embodiment uses a 12-axis drilling machine for circuit board processing, which includes six processing sections. The first spindle assembly and the second spindle assembly of each processing section simultaneously drill and process the circuit board of one station. Taking the example of each linkage connecting three first spindle assemblies and the corresponding three second spindle assemblies moving independently, the structure of the main circuit board processing equipment is described in detail.

[0047] In this embodiment, as Figure 1 , Figure 2 As shown, the circuit board processing equipment includes: a base 40, a crossbeam 30, processing sections 10, a worktable 20, etc. The worktable 20 is mounted on the base 40 and moves along a second direction. Six processing sections 10, which move along a first direction, are slidably mounted on the crossbeam 30 above the worktable 20. The first spindle 110 and the second spindle 120 of each processing section 10 move along a third direction to synchronously replicate the same circuit board 22 carried on the worktable 20, thereby improving processing efficiency. The first direction, the second direction, and the third direction are perpendicular to each other.

[0048] In this embodiment example, such as Figures 1 to 6As shown, the circuit board processing equipment includes: a crossbeam 30, on which six processing sections 10 are slidably connected along a first direction. Each processing section 10 includes a first spindle assembly 11 and a second spindle assembly 12; two connecting rods 13 respectively connect the three first spindle assemblies 11, which move synchronously along the first direction; each second spindle assembly 12 moves independently along the first and second directions, with the second direction perpendicular to the first direction; the first spindle assemblies 11 and the second spindle assemblies 12 synchronously replicate the same circuit board 22 carried on the worktable 20. This circuit board processing equipment allows for fine adjustment of the positions of the first spindle assemblies 11 and the second spindle assemblies 12, thereby improving the accuracy of synchronous replication processing.

[0049] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, each first spindle assembly 11 includes a first spindle 110 and a base plate 14. The base plate 14 is fixedly connected to a back plate 15, and the back plate 15 is slidably connected to a slide rail 162 on the crossbeam 30 via a slider 161. Figure 3 The diagram illustrates that the connecting rod 13 connects three first spindle assemblies 11 in series. Figure 1 Two sets of connecting rods connect three first spindle assemblies 11 in series. Specifically, the back plate 15 of the first spindle assembly 11 has rings through which connecting rods 13 pass, and the back plate 15 of the first spindle assembly 11 is fixedly connected to the connecting rods 13 through the rings. A first drive member 17 is also provided between the first spindle assembly 11 and the crossbeam 30. In the first direction, the first drive member 17 is located in the middle area of ​​the connecting rods 13, and in the third direction, the first drive member 17 is located between the two sliders 161. The first drive member 17 drives the three first spindle assemblies 11, the connecting rods 13, and the three back plates 15 to move synchronously along the first direction on the crossbeam 30 to adjust the position of the three first spindle assemblies 11 in the first direction. It should be noted that the worktable 20 moves relative to the crossbeam 30 and the machining section 10 along the second direction to adjust the position of the first spindle assembly 11 and the second spindle assembly 12 in the second direction as a whole.

[0050] In this embodiment, as Figure 2 , Figure 3 and Figure 5As shown, each second spindle assembly 12 includes a second spindle 120 and a base plate 14. The base plate 14 is fixedly connected to a back plate 15, and the back plate 15 is slidably connected to a slide rail 162 on the crossbeam 30 via a slider 161. A second drive member 18 is provided on the back plate 15 corresponding to each second spindle assembly 12. The second drive member 18 is located between the back plate 15 and the crossbeam 30, and in the third direction, the second drive member 18 is located between two sliders 161. The second drive member 18 corresponds one-to-one with the second spindle assembly 12, and each second drive member 18 independently drives the corresponding second spindle assembly 12 to move along the first direction on the crossbeam 30 to adjust the position of the second spindle assembly 12 in the first direction. Each second spindle assembly 12 is also provided with an adjustment part, which is a manual adjustment structure that applies a lateral pressing force to the second spindle 120 to finely adjust the position of the second spindle 120 in the second direction. In each second spindle assembly 12, the second spindle assembly 12 is independently driven to move along a first direction by a second drive member 18, and is independently driven to move along a second direction by an adjustment unit, so as to finely adjust the position of each second spindle assembly 12 individually.

[0051] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the back plate 15 is fixedly connected to the slider 161, which slides on the slide rail 162 on the crossbeam 30. A gap 19 is provided between the back plate 15 and the slider 161. The gap 19 is used to accommodate shims. By adding shims of different thicknesses in the gap, the perpendicularity of the first spindle assembly 11 and the second spindle assembly 12 in the third direction can be finely adjusted. In this example, an inclined surface forming the gap 19 is provided on the side of the slider 161 that abuts against the back plate 15. The inclined surface extends in the third direction, and the opening of the gap 19 faces the worktable 20.

[0052] In this embodiment, as Figure 1 and Figure 6 As shown, a pneumatic clamp assembly 21 is provided on the worktable 20. Each pneumatic clamp assembly 21 corresponds to a processing unit 10. The pneumatic clamp assembly 21 is used to detect, fix, and fine-tune the circuit board 22 carried on the worktable 20. The pneumatic clamp assembly 21 clamps a detection body 210, which is a cylindrical metal rod extending in a third direction. Figure 3 As shown, the plurality of first spindle components 11 include a target spindle component 111 and an object spindle component 112. In this embodiment, in the first direction, the leftmost first spindle component is the target spindle component 111, and the two immediately following first spindle components are the object spindle components 112. Figure 6As shown, the first spindle 110 of the target spindle assembly 111 clamps the detection element 211. The detection element 211 can rotate along the outer peripheral sidewall of the detection body 210 to detect the concentricity of the target spindle assembly 111 and the detection body 210. First, the position of the target spindle assembly 111 is determined, and then the position of the object spindle assembly 112 is determined based on the position of the target spindle assembly 111.

[0053] In the actual application of this embodiment, the position of the pneumatic clamp assembly 21 on the worktable 20 is first corrected so that the actual position of the circuit board 22 fixed by the pneumatic clamp assembly 21 is consistent with the theoretical position. It should be noted that the correction and adjustment of the pneumatic clamp assembly 21 are automatic, and will not be described in detail in this application. After the position of the pneumatic clamp assembly 21 is corrected, the pneumatic clamp assembly 21 is controlled to clamp the detection body 210 in the standard position. In this embodiment, the detection body 210 can be a standard rod. After the pneumatic clamp assembly 21 clamps the detection body 210, the processing unit 10 and the worktable 20 are controlled to move relative to each other in the first direction and the second direction, and the target spindle assembly 111 clamps the detection piece 211 close to the detection body 210. Both the detection element 211 and the detection body 210 extend along a third direction. The target spindle assembly 111 clamps the detection element 211 and rotates it along the outer peripheral sidewall of the detection body 210. The detection includes at least detection in the first and second directions. After multiple detections and adjustments to the position of the target spindle assembly 111, the concentricity between the detection body 210 and the target spindle assembly 111 is determined based on the measurement results on the detection element 211, thereby determining the position of the target spindle assembly 111 in the first and second directions. In this embodiment, the detection element 211 is a dial indicator.

[0054] After determining the position of the target spindle assembly 111, the positions of the two target spindle assemblies 112 are temporarily fixed because they are connected in series via a linkage. Then, in the other two processing units 10, the pneumatic clamp assemblies 21 corresponding to the two target spindle assemblies 112 are controlled to clamp the detection body 210 and align it with the target spindle assembly 112. Similarly, the position is detected and determined by rotating the detection body 211 in different directions. It should be noted that when determining the position of the target spindle assembly 111, the position of the target spindle assembly 111 is adjusted to align with the detection body 210 of the pneumatic clamp assembly 21; when determining the position of the target spindle assembly 112, the position of the detection body 210 of the pneumatic clamp assembly 21 is adjusted to align with the position of the target spindle assembly 112. In this way, the positions of the target spindle assembly 112 in the first and second directions can be determined. The control system records the coordinate positions of the three first spindle assemblies 11 by measuring with a grating ruler. Even if each spindle assembly or the worktable moves again, it can be restored to the coordinate position where the first spindle assembly 11 should be.

[0055] Within each machining section 10, the position of the second spindle assembly 12 is determined by the position of the first spindle assembly 11. Specifically, in the first direction, the connecting rod 13 connects three first spindle assemblies 11 in series. After determining the positions of the three first spindle assemblies 11, using the position of each first spindle assembly 11 as a reference, the relative positional deviation between the first spindle assembly 11 and the second spindle assembly 12 is first detected, and then the positions of the three second spindle assemblies 12 are adjusted respectively. Specifically, the relative positional deviation between the first spindle assembly 11 and the second spindle assembly 12 can be detected by moving them sequentially to the same tool setter. After determining the deviation, the deviation is adjusted by driving the corresponding second spindle assembly 12 to move along the first direction on the crossbeam using the second drive member 18 until each second spindle assembly 12 maintains a predetermined distance from the first spindle assembly 11. Thus, the position of the second spindle assembly 12 in the first direction is determined. The second spindle assembly 12 includes an adjustment section that applies a lateral pressing force to the second spindle 120, driving the second spindle 120 to move slightly in the second direction, thereby adjusting the relative position of the second spindle 120 and determining the position of the second spindle assembly 12 in the second direction.

[0056] After determining the positions of the first spindle assembly 11 and the second spindle assembly 12, the control processing unit 10 synchronously replicates and processes the corresponding circuit board 22. In this embodiment, to ensure the perpendicularity of the first spindle assembly 11 and the second spindle assembly 12, the perpendicularity needs to be detected before determining the coordinate position. If the perpendicularity does not meet the preset threshold requirement, the perpendicularity of the spindle assembly can be adjusted by adding a shim in the gap 19 between the slider 161 and the back plate 16.

[0057] In the circuit board processing equipment described in this embodiment, the first spindle assembly is connected in series, and the second spindle assembly moves independently. The concentricity of the first spindle assembly is detected and determined by the pneumatic clamp assembly on the worktable, thereby determining the position of each spindle assembly. This circuit board processing equipment has the following technical effects: (1) It can accurately adjust the positions of the first spindle assembly and the second spindle assembly, improving the accuracy of synchronous copy processing. (2) The position of the first spindle assembly is positioned by the pneumatic clamp assembly on the worktable, and the position of each first spindle assembly connected in series with the connecting rod is accurately positioned and adjusted. (3) After adjusting the position of each first spindle assembly individually, the position of the second spindle assembly is adjusted based on the position of the first spindle assembly, improving the accuracy of synchronous copy processing.

[0058] Example 2

[0059] This embodiment uses a 12-axis drilling machine for circuit board processing, which includes six processing sections. The first spindle assembly and the second spindle assembly of each processing section simultaneously drill and process the circuit board of one station. Taking the example of each linkage connecting three first spindle assemblies and the corresponding three second spindle assemblies moving independently, the structure of the main circuit board processing equipment is described in detail.

[0060] In this embodiment, as Figure 1 , Figure 2 As shown, the circuit board processing equipment of this utility model includes: a base 40, a crossbeam 30, a spindle assembly 10, a worktable 20, etc. The worktable 20 is disposed on the base 40 and moves along a second direction. Twelve spindle assemblies that move along a first direction are slidably connected on the crossbeam 30 above the worktable 20. The spindle of each spindle assembly moves along a third direction to process the circuit board 22 carried on the worktable 20. Two adjacent spindle assemblies 10 form a group and synchronously replicate the same circuit board 22 carried on the worktable 20 to improve processing efficiency. The first direction, the second direction, and the third direction are perpendicular to each other.

[0061] In this embodiment, as Figures 1 to 6 As shown, the circuit board processing equipment includes: a crossbeam 30, on which multiple processing units 10 are slidably connected along a first direction. Each processing unit 10 includes: a first spindle assembly 11, where a first drive member 17 drives three first spindle assemblies 11 connected in series by connecting rods 13 to move synchronously along the first direction; a control unit 21 on the worktable 20 aligns a detection body 210 held by a pneumatic clamp assembly 21 with the first spindle assembly 11 to determine the position of each first spindle assembly 11; and a second spindle assembly 12, where each second drive member 18 drives a corresponding second spindle assembly 12 to move along the first direction; and an adjustment unit adjusts the position of the second spindle assembly 12 in a second direction, which is perpendicular to the first direction. After determining the positions of each first spindle assembly 11 and second spindle assembly 12, the first spindle assembly 11 and second spindle assembly 12 of each processing unit synchronously replicate the same circuit board 22 carried on the worktable. This circuit board processing equipment determines the position of the first spindle assembly based on the air clamp assembly, and then determines the position of the second spindle assembly based on the position of the first spindle assembly. This allows for more precise positioning and adjustment of the positions of each spindle assembly, resulting in high spindle assembly positioning accuracy and improving the synchronous replication processing accuracy of the first and second spindle assemblies.

[0062] In this embodiment, the structures of the first and second spindle assemblies are the same as in Embodiment 1. The structures of the connecting rod, back plate, first drive member, second drive member, worktable, and pneumatic clamp assembly are also the same as in Embodiment 1, and will not be repeated here. The method for determining the positions of the first and second spindle assemblies is basically the same as in the embodiment, or may be adjusted as appropriate, and will not be repeated here. The difference from Embodiment 1 is that the pneumatic clamp assembly 21 in this embodiment clamps a pin. The first and second spindle assemblies move sequentially to the same tool inspection assembly to detect relative positional deviations. The adjustment unit is an automatic adjustment mechanism using an inclined slide rail structure, resulting in higher precision.
