Detailed Implementation

[0032] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0033] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] The specific embodiments of this disclosure are described below with reference to the accompanying drawings. In this document, terms such as "upper," "lower," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, and not to limit the absolute position of these related parts. In this document, terms such as "first," "second," "third," and "fourth" are used only to distinguish them from each other, and not to indicate degree of importance, order, or prerequisite for each other's existence. In this document, terms such as "equal," "same," "aligned," "vertical," "horizontal," "above," "consistent," "synchronous," "simultaneously," "in sequence," "copy," "top," "bottom," "further," and "lateral" are not strict mathematical and / or geometric limitations, and also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0035] like Figure 1 , Figure 2 As shown, the circuit board processing equipment of this disclosure includes: a base, a crossbeam, a spindle assembly, a worktable, etc. The worktable is disposed on the base and moves along a second direction. At least two spindle assemblies that move along a first direction are slidably mounted on the crossbeam above the worktable. The spindle of each spindle assembly moves along a third direction to process the circuit board carried on the worktable. At least two adjacent spindle assemblies 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 disclosure, the circuit board processing equipment can be implemented as a drilling equipment, a forming equipment, a milling machine, a drilling and milling integrated machine, etc., and is not limited herein. In the embodiments of this disclosure, the number of spindle assemblies of the circuit board processing equipment can be two, three, four, six, ten, twelve, etc., and is not limited herein.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, the spindle assembly 10 of this disclosure includes a base plate that slides on a crossbeam and moves along a first direction on the crossbeam. The base plate drives the spindle assembly to move along the first direction. The spindle assembly 10 also includes a spindle clamp and a drive unit. A guide rail is provided on the base plate, and a slider is provided on the spindle clamp. The slider slides on the guide rail, and the spindle clamp is slidably connected to the base plate. The drive unit is mounted on the base plate and drives the spindle and the spindle clamp as a whole to move along a third direction on the guide rail to process the circuit board carried on the worktable. In this disclosure, each spindle holds a tool at its bottom end. The spindle clamping the tool moves up and down along a third direction to achieve switching between multiple processing points. The tool rotation motor drives the tool to rotate at high speed to perform mechanical drilling on a single point on the circuit board. Fine-tuning the spindle position relative to the spindle clamp changes the center position of the spindle. Fine-tuning the relative center positions of multiple spindles brings their center positions together, thereby improving the accuracy of synchronous copying processing by multiple spindles.

[0037] In multi-spindle circuit board processing equipment, each spindle assembly can move independently along a first direction on the crossbeam. In the first direction, the positions of multiple adjacent spindle assemblies processing the same circuit board can be precisely adjusted in real time. That is, the center coordinates of multiple 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 the circuit board as a whole and moves along the second direction, the relative errors between each spindle assembly caused by assembly errors, vibration, wear, thermal expansion and contraction, etc., cannot be adjusted or compensated. To change the relative positions of multiple adjacent spindle assemblies in the second direction, it is necessary to adjust the position of a single spindle in the second direction.

[0038] To adjust the center position of the spindle and maintain the center position of multiple spindles within a preset range for synchronously copying and processing circuit boards at the same workstation, this disclosure provides a spindle assembly suitable for circuit board processing equipment. The assembly includes a base plate, a spindle clamp, and a spindle. The spindle is movably connected to the spindle clamp along a second direction. A drive unit drives the spindle clamp to move along a third direction. The spindle moves relative to the second and third directions on an inclined plane. In the second direction, the inclined plane adjusts the relative position of the spindle and the spindle clamp. The second and third directions are perpendicular to each other. This spindle assembly allows for fine-tuning of the spindle's position in the second direction to adjust the spindle's center position within a preset range, thereby improving the accuracy of synchronous copying and processing by multiple spindles.

[0039] In some embodiments of this disclosure, such as Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, the spindle assembly also includes a locking part 19, which includes a clamping block and a clamping member. The clamping block is fixedly mounted on the spindle sleeve outside the spindle, and the clamping member is mounted on the spindle clamp. The clamping member clamps the clamping block circumferentially to lock it. The clamping member and the clamping block can switch between a locked state and a released state. The clamping block of the locking part is fixedly connected to the outer circumferential side of the spindle sleeve, and the clamping member is fixedly connected to the spindle clamp. The locking part switches between a locked state and a released state. When the pneumatic component controls the clamping member to clamp the clamping block circumferentially, the locking part is in the locked state, and the spindle is locked to the spindle clamp by the locking part, preventing relative displacement between the two. When the pneumatic component controls the clamping member to release the clamping block circumferentially, the locking part is in the released state, and the spindle and the spindle clamp are movably connected, allowing relative displacement between them. It should be noted that the spindle clamp is circumferentially semi-encircling the outside of the spindle. The clamping element extends from the outer side through the spindle clamp into the inner side, approaching the clamping block circumferentially. By clamping the clamping block, it prevents second and third-dimensional displacement between the spindle and the spindle clamp. When the spindle position needs to be adjusted, the control locking part is in the released state; when the spindle position is adjusted, the control locking part is in the locked state.

[0040] In some embodiments of this disclosure, such as Figure 4 , Figure 5 , Figure 6As shown, the first connecting part is movably connected to the spindle and the spindle clamp; a wedge 17 is provided on the bottom of the base plate near the spindle, and the side of the wedge facing the spindle is an inclined surface 18, which the spindle moves along a third direction to abut against the inclined surface. Specifically, a wedge is provided on the side of the bottom of the base plate, and an inclined surface is provided on the side of the wedge facing the spindle. The control drive unit drives the spindle and the spindle clamp to move downward along the third direction until at least a part of the spindle abuts against the inclined surface. When the drive unit drives the spindle clamp and the spindle to continue moving downward along the third direction, due to the obstruction and squeezing force of the inclined surface, the spindle is caused to move slightly relative to the spindle clamp in the second direction and the third direction, and the position adjustment of the spindle in the second direction is achieved by the inclined surface. Specifically, since the first connecting part is movably connected to the spindle and the spindle clamp, in this embodiment, the first connecting part includes a slide rail and a slider. The slide rail extends along the second direction, and the slider moves on the slide rail to achieve a sliding connection along the second direction. The first connecting part slidably connects the spindle and the spindle clamp along the second direction. An elastic element is also provided between the spindle and the spindle clamp, which movably connects the spindle and the spindle clamp. A drive unit drives the spindle and spindle clamp to move along a third direction on the guide rails of the base plate until at least a portion of the spindle abuts against the inclined surface on the wedge. The inclined surface is inclined along the second and third directions. The drive unit drives the spindle and spindle clamp to continue moving along the third direction on the inclined surface. Due to the obstruction of the inclined surface, a compressive force in the second direction is applied to the spindle, causing the spindle to make slight movements on the inclined surface of the wedge. This slight movement changes the position of the spindle relative to the spindle clamp in the second direction. This achieves spindle center position adjustment, allowing the center positions of multiple spindles to be adjusted to a preset range, thereby improving the synchronous replication machining accuracy of multiple spindles.

[0041] In some embodiments of this disclosure, such as Figure 5 , Figure 6As shown, in the third direction, the height of the inclined surface of the wedge block is less than the spacing between the main shaft and the workbench. Specifically, the wedge block is fixed to the bottom of the bottom plate and faces the main shaft side. The inclined surface of the wedge block extends in the second and third directions. When the main shaft moves in the third direction and abuts against the inclined surface, the inclined surface blocks the movement of the main shaft, and the inclined surface provides a squeezing force in the second and third directions to the main shaft. This squeezing force causes the main shaft to displace in the second and third directions. Therefore, the main shaft micro-moves simultaneously in the second and third directions along the inclination angle ∠A of the inclined surface. When the main shaft displaces along the inclined surface, in order to prevent the main shaft and the tool or standard bar clamped by it from touching the workbench, causing interference or collision, a reasonable height of the inclined surface needs to be set so as not to cause a safety accident to the main shaft. In the third direction, the height D2 of the inclined surface is less than the spacing D1 between the main shaft and the workbench. The maximum displacement of the main shaft in the third direction on the inclined surface is within the range of this spacing D1, and the main shaft will not touch the workbench. On the other hand, in order to further limit the movement stroke of the main shaft and prevent safety hazards, a stroke limit of the main shaft on the inclined surface is set. In the third direction, the spacing D3 between the stroke limits is less than the height D2 of the inclined surface, further improving the displacement safety of the main shaft in the third direction. Therefore, in the third direction, the spacing between the main shaft and the workbench is D1, the height of the inclined surface is D2, and the spacing between the stroke limits of the main shaft on the inclined surface is D3, where D3 < D2 < D1, that is, D3 is less than D2 and D2 is less than D1. It should be noted that the spacing between the main shaft and the workbench refers to the spacing between the lowest point of the main shaft moving in the third direction and the upper surface of the workbench in the machining state, and this lowest point does not include the tool.

[0042] In some embodiments of the present disclosure, such as Figures 7 to 11As shown, a first connecting part is movably connected to the spindle and the spindle clamp; a second connecting part is movably connected to the top end of the spindle and the base plate; the second connecting part 16 includes a protrusion and a groove, one of which is slidably connected to the spindle, and the protrusion and groove cooperate to lock or release the spindle. Specifically, the top end of the spindle is connected to the second connecting part, the second connecting part is connected to the base plate, and the top end of the spindle is suspended on the base plate in a third direction through the second connecting part. The second connecting part includes a protrusion and a groove. When the groove is fixed on the base plate, the protrusion is slidably connected to the top end of the spindle; or, the protrusion is fixed on the base plate, and the groove is slidably connected to the top end of the spindle. The protrusion and groove cooperate to lock or release the spindle, restricting the movement of the spindle in a third direction. When the protrusion slides into the groove, the control switch of the pneumatic element connected to the groove is opened, and the groove clamps the protrusion from the side, restricting the movement of the protrusion in a third direction; when the control switch of the pneumatic element is closed, the groove releases the protrusion, and the protrusion and the spindle can move in a third direction. The cooperation of the protrusion and the groove can lock or release the spindle. At the top of the spindle, the spindle is slidably connected to a protrusion. Specifically, the protrusion is fixedly connected to a slider, and a slide rail is provided at the top of the spindle. The slide rail extends along a second direction or a second and third direction. The slider slides on the slide rail, causing the protrusion and the top of the spindle to slide relative to the spindle clamp along the second direction or the second and third direction. Preferably, elastic elements are provided at both ends of the slide rail to limit the relative displacement limit between the protrusion and the spindle, protecting the spindle from collision or interference. It should be noted that the positions of the protrusion and the groove are not limited. The groove can also be slidably connected to the top of the spindle. Correspondingly, the groove is fixedly connected to the slider, and in conjunction with the slide rail at the top of the spindle, the groove and the spindle are slidably connected along the second direction or the second and third direction. The slider slides along the slide rail along the second direction, causing the spindle to move relative to the spindle clamp along the second direction. Alternatively, the slider slides along the slide rail along the second and third directions, causing the spindle to move relative to the spindle clamp along the second and third directions. The base plate restricts the movement of the spindle along the third direction through the protrusion and the groove. Therefore, when the spindle is suspended from the base plate along a third direction via the second connecting part, the spindle can slide relative to the spindle clamp along a second direction or both the second and third directions. This positional structure allows for fine-tuning of the spindle's center position, enabling the spindle to move slightly in the second direction.

[0043] In some embodiments of this disclosure, such as Figure 7As shown, an inclined surface is provided at the first connecting part, which is slidably connected to the main shaft and the main shaft clamp; the protrusion is slidably connected to the main shaft along the second direction. Specifically, when the first connecting part is provided with an inclined surface, the first connecting part includes a sliding connection structure in the inclined direction, so that the side of the main shaft is slidably connected to the main shaft clamp in an inclined direction. The inclined direction of this inclined surface is along the second and third directions. Specifically, a slide rail is provided on the main shaft clamp, and a slider is provided on the main shaft sleeve outside the main shaft. The slide rail extends along the second and third directions, and there is an inclined surface extending along the second and third directions between the slider and the slide rail. The slider slides on the slide rail, causing the main shaft to slide relative to the main shaft clamp along the second and third directions on the inclined surface, providing conditions for micro-movement between the main shaft and the main shaft clamp in the second direction.

[0044] For example Figure 7 and Figure 10 As shown, the second connecting part movably connects the top end of the spindle and the base plate. The top end of the spindle can slide along the second direction, and the spindle can slide laterally along the second and third directions on the inclined surface. When the drive unit drives the spindle clamp to move upward along the third direction on the guide rail of the base plate, the spindle moves relative to the spindle clamp along the second and third directions on the inclined surface of the first connecting part. Due to the obstruction and squeezing force of the inclined surface, the spindle can move relative to the spindle clamp simultaneously along the second and third directions. The inclined surface adjusts the relative position of the spindle and the spindle clamp in the second direction. Thus, the movement of the spindle clamp in the third direction can be controlled to achieve micro-motion of the spindle position in the second direction, thereby achieving the purpose of adjusting the center position of the spindle.

[0045] In some embodiments of this disclosure, such as Figure 9 and Figure 11 As shown, an inclined surface is disposed between the second connecting part and the main shaft, and the main shaft is slidably connected to the second connecting part and the base plate; the first connecting part is slidably connected to the main shaft and the main shaft clamp along the second direction. Specifically, when an inclined surface is disposed between the second connecting part and the main shaft, the second connecting part is slidably connected to the top end of the main shaft at an inclination, and the inclination direction of this inclined surface is along the second direction and the third direction. The second connecting part includes a protrusion and a groove, the groove is disposed on the base plate, and the protrusion is slidably connected to the top end of the main shaft at an inclination via a slider and a slide rail. The slider is fixed on the protrusion, and the slide rail is fixed on the top end of the main shaft. The slide rail is inclined along the second direction and the third direction, and there is an inclined surface between the slider and the slide rail at an inclination along the second and third directions. That is, the slide rail is in an inclination direction, the slider slides on the slide rail at an inclination direction, the protrusion and the main shaft slide relative to each other at an inclination direction, and the main shaft can slide relative to the main shaft clamp on the inclined surface at an inclination along the second and third directions.

[0046] like Figure 9 and Figure 11As shown, the top of the spindle is suspended from the base plate via a second connecting part, and the spindle slides relative to the spindle clamp on an inclined plane. Laterally, the spindle is slidably connected to the spindle clamp along a second direction via a spindle sleeve; this slidable connection is also achieved through a slider and a slide rail. Therefore, the spindle can slide laterally along the second direction, and the top of the spindle can slide along both the second and third directions on the inclined plane. When the drive unit drives the spindle and spindle clamp as a whole to move upwards along the third direction on the guide rail of the base plate, the spindle clamp moves relative to the spindle along the third direction on the inclined plane between the second connecting part and the top of the spindle. Due to the guiding and compressive force of the inclined plane, the spindle moves simultaneously relative to the spindle clamp along both the second and third directions. This allows for the control of the spindle clamp's movement in the third direction, enabling micro-movement of the spindle along the second direction and achieving the purpose of adjusting the spindle's center position.

[0047] This disclosure also provides a control method for circuit board processing equipment, adapted to adjust the position of the spindle in a second direction during circuit board processing. Specifically, it includes the following steps: S100: Controlling the locking part to switch to a released state, with the first connecting part movably connected to the spindle and the spindle clamp; S200: Controlling the second connecting part to switch to a locked state, with the second connecting part fixedly connected to the base plate, and the top end of the spindle movably connected to the second connecting part; S300: Controlling the driving component to drive the spindle clamp to move along a third direction, with the spindle moving relative to the second and third directions on an inclined plane. In the second direction, the inclined plane adjusts the relative position of the spindle and the spindle clamp, and the second and third directions are perpendicular to each other. This control method can achieve micro-movement of the spindle in the second direction, thereby adjusting the center position coordinates of multiple spindles processing the same circuit board to maintain consistency, improving processing efficiency while also increasing processing accuracy.

[0048] Specifically, such as Figure 7As shown, when the first connecting part is a sloping sliding connection, the main shaft is laterally connected to the main shaft clamp via the main shaft sleeve on the inclined slider and slide rail. The top end of the main shaft is slidably connected to the second connecting part along the second direction. The steps for adjusting the position of the main shaft include: First, controlling the locking part to unlock, the main shaft is laterally connected to the main shaft clamp in a released state, so that the main shaft can move slightly in the second direction. Second, controlling the second connecting part to switch to a locked state, the second connecting part is fixedly connected to the base plate, and the top end of the main shaft is suspended on the base plate via the second connecting part. Specifically, controlling the main shaft and the main shaft clamp to move upward along the third direction, driving the protrusion at the top end of the main shaft to move towards the groove on the base plate until the protrusion cuts into the groove. The pneumatic control switch is turned on, the groove locks the protrusion from the circumferential direction, and the main shaft connected to the protrusion is suspended on the base plate. In this embodiment, the main shaft and the protrusion are slidably connected, the slider is fixedly installed on the protrusion, the slide rail is fixedly installed on the top end of the main shaft, the slider and the slide rail extend along the second direction, and the two slide relative to each other along the second direction, causing the main shaft to slide relative to the main shaft clamp in the second direction. Finally, the control drive unit drives the spindle clamp to move upward along the third direction, and the spindle moves relative to the spindle clamp along the second and third directions on the inclined surface of the first connection part. Due to the obstruction and squeezing force of the inclined surface, the spindle moves slightly along the second and third directions. With the help of the inclined surface, the relative micro-movement of the spindle along the second direction is achieved by controlling the movement of the spindle clamp along the third direction, thereby adjusting the position of the spindle in the second direction.

[0049] In another preferred embodiment, such as Figure 9 and Figure 11As shown, when the second connecting part and the main shaft are connected by an inclined sliding connection, the top end of the main shaft is slidably connected to the second connecting part via an inclined slider and slide rail, and the second connecting part is suspended from the base plate; the main shaft is laterally slidably connected to the first connecting part along the second direction. The steps for adjusting the position of the main shaft include: First, controlling the locking part to unlock, the main shaft is laterally connected to the main shaft clamp in a released state, so that the main shaft can move slightly in the second direction. Second, controlling the second connecting part to switch to the locked state, the second connecting part is fixedly connected to the base plate, and the top end of the main shaft is suspended from the base plate through the second connecting part. Specifically, controlling the main shaft and the main shaft clamp to move as a whole along the third direction, driving the protrusion at the top end of the main shaft to move towards the groove on the base plate until the protrusion cuts into the groove, the pneumatic control switch is turned on, the groove locks the protrusion from the circumferential direction, and the main shaft connected to the protrusion is suspended from the base plate. In this embodiment, the spindle and the protrusion are connected by an inclined sliding connection. The slider is fixedly mounted on the protrusion, and the slide rail is fixedly mounted on the top of the spindle. The slide rail extends along the second and third directions. An inclined ramp is included between the slider and the slide rail. The slider moves on the slide rail, causing the spindle to slide relative to the spindle clamp on the ramp. Finally, the control drive drives the spindle clamp to move upward along the third direction. The spindle moves relative to the spindle clamp along the second and third directions on the ramp between the second connection and the top of the spindle. Due to the obstruction and squeezing force of the ramp, the spindle makes slight movements along the second and third directions. The ramp adjusts the relative position of the spindle and the spindle clamp, thereby achieving relative slight movements of the spindle in the second direction through the movement of the spindle clamp in the third direction, and adjusting the position of the spindle in the second direction.

[0050] In the above embodiments of this disclosure, before step S300, the method includes acquiring the deviation of the spindle in the second direction, and adjusting the relative position of the spindle in the second direction according to the grating ruler on the base plate and the reading head on the spindle clamp. Figure 6 As shown, before the control drive unit drives the spindle clamp to move in the third direction, the method further includes obtaining the deviation S of the spindle in the second direction. This deviation S is determined based on the deviation between the actual coordinate position and the theoretical coordinate position of the spindle, as well as the inclination angle ∠A of the inclined plane. Using the tangent trigonometric function, the relative movement distance H of the spindle clamp in the second direction is determined. Referring to the grating ruler on the base plate and the reading head on the spindle clamp, it is determined that the spindle clamp has moved to a preset position range. The inclination angle ∠A of the inclined plane is fixed. The movement distance H of the spindle clamp in the second direction is measured using the grating ruler and the reading head, and the movement distance S of the spindle in the second direction is calculated and determined using the tangent trigonometric function. This method allows for indirect adjustment of the spindle position based on the actual deviation S. It is simple to measure, convenient to adjust, low in cost, and highly accurate.

[0051] Following step S300, the process further includes controlling the locking part to switch to the locked state, with the spindle fixedly connected to the spindle clamp via the locking part. When the position of the spindle in the second direction is adjusted to a preset range, it is necessary to maintain and lock the spindle to prevent further relative displacement in the second direction. Therefore, after adjustment, the locking part is controlled to switch to the locked state, and the spindle is laterally locked to the spindle clamp. Simultaneously, the second connecting part is controlled to switch to the released state, the groove no longer locks the protrusion, and the spindle is fixedly connected to the spindle clamp via the locking part.

[0052] In the embodiments of this disclosure, when the spindle's perpendicularity is within a preset range, the spindle's center coordinates are used to determine its center position. Specifically, the spindle's center coordinates can be detected and determined by detecting the tool tip of the clamped tool at the bottom of the spindle, using a tool setter or tool inspection assembly. Simultaneously, when the spindle's center coordinates are outside the preset range, the worktable moves relative to the spindle, changing the center coordinates of all spindles in the second direction; a single spindle slides along the first direction on the crossbeam, changing its center coordinates in the first direction, thus adjusting the spindle's center coordinates. When multiple spindles simultaneously replicate the same circuit board, the center coordinates of one spindle in the second direction are first adjusted by the worktable's movement. Using this spindle's center coordinates as a reference, the center coordinates of at least one other spindle are fine-tuned, ensuring that the center coordinates of the multiple spindles in the first direction are spaced at a predetermined distance, while the center coordinates in the second direction remain essentially consistent, thereby improving the accuracy of simultaneous replication of the same circuit board by multiple spindles. In the embodiments of this disclosure, maintaining consistent center coordinates in the second direction of multiple spindles means adjusting the Y-coordinates of these spindles to a preset accuracy threshold range. In the first direction, these spindle spacings are predetermined distances.

[0053] In the embodiments disclosed herein, the center position of the spindle is fine-tuned. Fine-tuning here 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 requiring adjustment may be 20 micrometers, 10 micrometers, or even a few micrometers. Such orders-of-magnitude fine-tuning, through precise adjustment of the drive components, can effectively improve accuracy.

[0054] Example 1

[0055] This embodiment takes a 12-axis drilling machine as an example, in which two spindle assemblies simultaneously drill and process a circuit board at one station, to explain in detail the structure of the spindle assembly, the structure of the circuit board processing equipment, and the circuit board processing control method.

[0056] In this embodiment, as Figure 1 , Figure 2As shown, the circuit board processing equipment includes: a base 40, a crossbeam 30, a spindle assembly 10, a worktable 20, etc. The worktable 20 is set on the base 40 and moves along a second direction. Twelve spindle assemblies 10, which move along a first direction, are slidably mounted on the crossbeam 30 above the worktable 20. The spindle 13 of each spindle assembly 10 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.

[0057] In this embodiment example, such as Figures 1 to 4 As shown, the circuit board processing equipment includes two spindle assemblies 10, which synchronously replicate the same circuit board 22 carried on a worktable 20. Each spindle assembly includes a spindle 13, which is movably connected to a spindle clamp 12 along a second direction. An elastic element 155 is movably connected to the top of the spindle 13 and the spindle clamp. A slope 18 facing the spindle 13 is provided on the bottom of a base plate 11. A control drive unit drives the spindle 13 and the spindle clamp 12 to move along a third direction. The spindle 13 moves relative to the spindle clamp along the second and third directions on the slope 18. In the second direction, the slope 18 adjusts the relative position of the spindle 13 and the spindle clamp 12. The second and third directions are perpendicular to each other. This circuit board processing equipment can fine-tune the position of the spindle 13 in the second direction to adjust the center position of multiple spindles synchronously replicating the same circuit board to be consistent, thereby improving processing accuracy.

[0058] In this embodiment, as Figure 4 As shown, the spindle assembly 10 includes a base plate 11, a spindle clamp 12, and a spindle 13. The spindle 13 is movably connected to the spindle clamp 12 along a second direction. A drive unit drives the spindle 13 and the spindle clamp 12 to move along a third direction. The spindle 13 moves relative to the spindle clamp along both the second and third directions on an inclined plane 18. In the second direction, the inclined plane 18 adjusts the relative position of the spindle 13 and the spindle clamp 12. The second direction and the third direction are perpendicular to each other. This spindle assembly 10 is applied to circuit board processing equipment, and the position of the spindle 13 in the second direction can be adjusted to keep the center positions of multiple spindles that are synchronously copying the same circuit board consistent, thereby improving the accuracy of multi-axis synchronous copying processing.

[0059] In this embodiment, as Figure 4 , Figure 5As shown, the first connecting part 15 is movably connected to the spindle 13 and the spindle clamp 12; a wedge 17 facing the spindle 13 is fixedly provided at the bottom of the base plate 11, and an inclined surface 18 facing the spindle 13 is provided on the side of the wedge 17 facing the spindle, the inclined surface 18 extending obliquely along the second direction and the third direction. The driving member drives the spindle 13 and the spindle clamp 12 to move along the third direction, and a part of the bottom end of the spindle 13 abuts against the surface of the inclined surface 18; the inclined surface 18 blocks the movement of the spindle 13, applies a compressive force in the second direction to the spindle 13, and causes the spindle 13 to move relative to the second direction and the third direction on the inclined surface 18. The inclined surface 18 of the wedge 17, in conjunction with the sliding connection of the first connecting part 15 in the second direction, converts the third-direction movement of the spindle 13 and the spindle clamp 12 into micro-movements of the spindle 13 in the second direction and the third direction, thus fine-tuning the relative position of the spindle 13 in the second direction.

[0060] exist Figure 5 In this design, wedge 17 has a triangular structure, narrower at the top and wider at the bottom. Its back is fixed to the side of the bottom of base plate 11, and its inclined surface 18 faces the spindle 13. Wedge 17 has sufficient width in the second direction, exceeding the gap between the spindle 13 and base plate 11. This width allows the spindle 13 to abut against the inclined surface 18 of wedge 17 when moving in the third direction. Simultaneously, wedge 17 has a third-direction height D2, which is less than the distance D1 between the spindle 13 and worktable 20. The installation height of wedge 17 and the height of its inclined surface ensure that the spindle 13 does not touch the inclined surface 18 during operation, and the bottom surface of wedge 17 does not touch the worktable 20. Wedge 17 and inclined surface 18 do not interfere with the third-direction movement of the spindle 13.

[0061] In this embodiment, as Figure 4 As shown, the first connecting part movably connects the main shaft and the main shaft clamp; the first connecting part 15 includes a slider and a slide rail, the slide rail is fixed on the main shaft clamp 12, the slider is fixed on the main shaft sleeve 14 outside the main shaft 13, the slide rail extends along a second direction, and the slider slides relative to the slide rail, causing the main shaft 13 and the main shaft clamp 12 to slide relative to each other along the second direction. An elastic element 155 is provided between the main shaft 13 and the main shaft clamp 12, and the top end of the main shaft 13 and the main shaft clamp 12 are connected by the elastic element 155 extending along the second direction. The elastic element 155 is implemented as a spring, which can provide a spring force opposite to the compressive force of the inclined plane 18 between the main shaft 13 and the main shaft clamp 12. The spring force can provide a driving force for reverse movement when the compressive force causes the main shaft 13 to slightly move in the second direction due to overload. The elastic force causes the main shaft 13 to move slightly upward relative to the main shaft clamp 12 along the second and third directions on the inclined plane 18, while the compressive force causes the main shaft 13 to move slightly downward relative to the main shaft clamp 12 along the second and third directions on the inclined plane 18. The main shaft 13 can move slightly upward and downward on the inclined plane, which makes it possible to achieve precise position adjustment in the second direction.

[0062] exist Figure 3 , Figure 4 In this design, a locking part 19 is provided between the spindle 13 and the spindle clamp 12. The locking part 19 includes a clamping block on the outside of the spindle sleeve 14 and a clamping member on the spindle clamp 12. The clamping member clamps the clamping block circumferentially to switch between a locked state and a released state. When the locking part 19 is switched to the locked state, the spindle 13 and the spindle clamp 12 are locked and fixedly connected, preventing relative displacement. When the locking part 19 is switched to the released state, the spindle 13 can make a slight movement in a second direction relative to the spindle clamp 12 to adjust the center position of the spindle 13. The locking part 19 provides the prerequisite for adjusting the position of the spindle 13.

[0063] In this embodiment, the control method in the spindle assembly 10 and the circuit board processing equipment includes the following steps:

[0064] S500: The control locking part is switched to the released state, and the first connecting part is movably connected to the spindle and the spindle clamp.

[0065] The first connecting part 15 slidably connects the main spindle 13 and the main spindle clamp 12. The first connecting part 15 includes a slider and a slide rail. The slider is mounted on the main spindle sleeve 14 on the outside of the main spindle, and the slide rail is mounted on the main spindle clamp 12. The slide rail extends along a second direction, and the slider slides on the slide rail. The main spindle 13 slides relative to the main spindle clamp 12 along the second direction. When the control locking part 19 switches to the released state, the main spindle 13 and the main spindle clamp 12 are no longer constrained, but the main spindle clamp 12 is slidably connected to the main spindle 13 through the first connecting part 15. The main spindle 13 and the main spindle clamp 12 can only move slightly along the second direction.

[0066] S600: Controls the spindle to move along a third direction until it abuts the inclined surface of the base plate wedge.

[0067] The drive unit drives the spindle 13 and spindle clamp 12 to move together along a third direction on the guide rail of the base plate until at least a portion of the spindle 13 abuts against the inclined surface 18 of the wedge block 17. The wedge block 17 is mounted on the bottom of the base plate 11, with its inclined surface facing the spindle 13 and inclined along the second and third directions. When the spindle 13 and spindle clamp 12 move together along the third direction, the bottom end of the spindle 13 rigidly abuts against the inclined surface 18 of the wedge block 17. The inclined surface 18 blocks the movement of the spindle 13 along the third direction but does not block the movement of the spindle clamp 12 along the second direction. The inclined surface 18 provides a compressive force to the spindle 13 along the second direction.

[0068] S700: The control drive unit drives the spindle and spindle clamp to move along a third direction. The spindle moves relative to the third direction on the inclined plane along a second direction. In the second direction, the inclined plane adjusts the relative position of the spindle and spindle clamp. The second direction is perpendicular to the third direction.

[0069] After the spindle 13 abuts against the inclined plane 12, the drive unit drives the spindle 13 and the spindle clamp 12 to continue moving along a third direction on the guide rail of the base plate 11. The spindle 13 continues to move along the third direction. Due to the obstruction of the inclined plane 18, the squeezing force provided by the inclined plane 18 to the spindle 13 drives the spindle 13 to move along a second direction. The driving force provided by the drive unit drives the spindle 13 to move along a third direction. The spindle 13 moves relative to the spindle clamp 12 along the second and third directions on the inclined plane 18. Since the spindle 13 and the spindle clamp 12 are slidably connected along the second direction through the first connecting part 15, at this time, the spindle clamp 12 moves along the third direction, and the spindle 13 moves along both the second and third directions. The spindle 13 moves relative to the spindle clamp 12 along the second direction. The inclined plane 18 changes the relative position of the spindle 13 and the spindle clamp 12 in the second direction.

[0070] In this embodiment, before step S700, the method further includes: acquiring the deviation of the spindle 13 in the second direction, and adjusting the relative position of the spindle 13 in the second direction based on the grating ruler on the base plate 11 and the reading head on the spindle clamp 12. The base plate 11 is equipped with a grating ruler, and the spindle clamp 12 is equipped with a reading head. The spindle 13 and the spindle clamp 12 move together along a third direction on the slide rail of the base plate. The reading head moves relative to the grating ruler, allowing the acquisition of the relative displacement. Therefore, as... Figure 6 As shown, after obtaining the deviation S of the spindle 13 in the second direction, the distance H of the spindle and spindle clamp moving along the third direction is calculated and determined based on the tilt angle ∠A of the wedge's inclined surface 18 and the tangent trigonometric function. Then, based on the reading head and grating ruler, the actual movement distance of the spindle and spindle clamp in the third direction is accurately obtained and adjusted in real time, thereby adjusting the deviation of the spindle 13 in the second direction. This ensures that the actual coordinate position of the spindle 13 in the second direction is consistent with the theoretical coordinate position, guaranteeing the consistency of the positions of the two spindle assemblies processing the same circuit board in the second direction; and improving the accuracy of synchronous copy processing with dual spindles.

[0071] Following step S700, the process further includes: controlling the locking part 19 to switch to the locked state, with the spindle 13 fixedly connected to the spindle clamp 12 via the locking part 19 and the first connecting part 15. After adjusting the position of the spindle 13 in the second direction, it is necessary to maintain the position of the spindle 13 to ensure machining accuracy. Therefore, the locking part 19 is switched to the locked state, and the clamping member of the locking part 19 locks the clamping block circumferentially, fixing the clamping block on the clamping member. Through the locking part 19, the spindle 13 is locked on the spindle clamp 12, and the sliding connection of the first connecting part 15 is locked, preventing relative sliding. The spindle 13 and the spindle clamp 12 cannot experience relative displacement in the second and third directions. The spindle 13 is fixedly connected to the spindle clamp 12 via the locking part 19 and the first connecting part 15, ensuring that the position of the spindle 13 no longer changes relative to the others.

[0072] This spindle assembly, circuit board processing equipment, and circuit board processing equipment control method can achieve fine-tuning of the spindle position by adjusting the relative position of the spindle and spindle clamp in the second direction through the inclined plane. In the second direction, the coordinate positions of multiple spindles that are synchronously copying the same circuit board can be adjusted to be consistent, thereby improving processing efficiency and accuracy of synchronous copying processing.

[0073] Example 2

[0074] This embodiment uses a circuit board processing equipment with twelve spindle assemblies, where two spindle assemblies synchronously replicate drilling and processing of a circuit board at one station, to illustrate in detail the structure of the spindle assembly, the structure of the circuit board processing equipment, and the circuit board processing control method.

[0075] In this embodiment, as Figure 1 , Figure 2 As shown, the circuit board processing equipment in this disclosure 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 10 that move along a first direction are slidably mounted on the crossbeam 30 above the worktable 20. The spindle 13 of each spindle assembly 10 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.

[0076] In this embodiment example, such as Figure 2 , Figure 3 , Figure 7 As shown, the circuit board processing equipment includes: two spindle assemblies 10, which synchronously replicate the same circuit board 22 carried on a worktable. At least one spindle assembly 10 includes: a spindle 13; a first connecting part 15 movably connected to the spindle 13 and a spindle clamp 12; and a second connecting part 16 movably connected to the top end of the spindle 13 and a base plate 11. The first connecting part 15 is provided with an inclined surface. A control drive unit drives the spindle clamp 12 to move along a third direction, and the spindle 13 moves relative to the spindle clamp along a second direction and a third direction on the inclined surface 18. In the second direction, the inclined surface 18 adjusts the relative position of the spindle 13 and the spindle clamp 12. The second and third directions are perpendicular to each other. This circuit board processing equipment can fine-tune the position of the spindle 13 in the second direction to adjust the center position of multiple spindles synchronously replicating the same circuit board to be consistent, thereby improving processing accuracy.

[0077] In this embodiment, as Figure 7As shown, the spindle assembly 10 includes a base plate 11, a spindle clamp 12, and a spindle 13. The spindle 13 is movably connected to the spindle clamp 12 along a second direction. A drive unit drives the spindle clamp 12 to move upward along a third direction. The spindle 13 moves relative to the spindle clamp along the second and third directions on an inclined plane 18. In the second direction, the inclined plane 18 adjusts the relative position of the spindle 13 and the spindle clamp 12. The second direction and the third direction are perpendicular to each other. This spindle assembly 10 is applied to circuit board processing equipment, and the position of the spindle 13 in the second direction can be adjusted to keep the center positions of multiple spindles that are synchronously copying the same circuit board consistent, thereby improving the accuracy of multi-axis synchronous copying processing.

[0078] In this embodiment, as Figure 7 As shown, the first connecting part is movably connected to the main shaft and the main shaft clamp; an inclined surface 18 is provided on the first connecting part 15, which includes a slider and a slide rail. The slider is fixed on the main shaft sleeve 14 outside the main shaft 13, and the slide rail is fixed on the main shaft clamp 12. The slide rail extends along a second direction and a third direction, and an inclined surface 18 extending along the second direction and a third direction is formed between the slider and the slide rail. The slider slides relative to the slide rail, and the main shaft 13 moves relative to the main shaft clamp 12 along the second and third directions on the inclined surface 18. The main shaft 13 and the main shaft clamp 12 are slidably connected along the second direction and a third direction through the first connecting part 15, which provides the precondition for the relative movement of the main shaft 13 and the main shaft clamp 12.

[0079] In this embodiment, as Figure 7 , Figure 10 As shown, the second connecting part movably connects the top end of the spindle and the base plate; the top end of the spindle 13 is suspended on the base plate 11 via the second connecting part 16. The second connecting part 16 includes a protrusion 162 and a groove 161, which cooperate to lock or release the spindle 13. The groove 161 is provided on the base plate 11, and the protrusion 162 is slidably connected to the top end of the spindle 13. When the control switch is turned on, the groove 161 clamps the protrusion 162 from the side, restricting the movement of the protrusion 162 and the spindle 13 in a third direction; when the control switch is turned off, the groove 161 releases the protrusion 162, and the protrusion 162 and the spindle 13 can move in a third direction. Figure 10 As shown, a slider 165 and a slide rail 166 are provided between the top end of the main shaft 13 and the second connecting part 16. The slider 165 is fixedly connected to the protrusion 162 of the second connecting part 16, and the slide rail 166 is fixed to the top end of the main shaft 13. The slide rail 166 extends along the second direction, and the slider 165 slides on the slide rail 166. The main shaft 13 slides relative to the second connecting part 16 and the base plate 11. Due to the sliding connection between the main shaft 13 and the second connecting part 16 and the base plate 11, micro-movement of the main shaft 13 along the second direction is possible.

[0080] like Figure 7As shown, the spindle 13 can slide laterally on the inclined surface 18 of the first connecting part 15 along the second and third directions; the top end of the spindle 13 is suspended from the base plate 11 through the second connecting part 16, and can slide relative to it in the second direction, but cannot move in the third direction. When the control drive unit drives the spindle clamp 12 to move upward along the third direction on the guide rail of the base plate 11, the spindle 13 moves relative to the spindle clamp 12 in the second and third directions on the inclined surface 18 of the first connecting part 15. Due to the blocking and squeezing force of the inclined surface 18, the spindle 13 can move relative to the spindle clamp 12 in both the second and third directions simultaneously. In the second direction, the inclined surface 18 adjusts the relative position of the spindle 13 and the spindle clamp 12. Thus, the movement of the spindle clamp 12 in the third direction can be controlled to achieve micro-movement of the spindle 13 in the second direction, thereby achieving the purpose of adjusting the center position of the spindle.

[0081] In this embodiment, as Figure 7 As shown, a locking part 19 is provided laterally between the spindle 13 and the spindle clamp 12. The locking part 19 includes a clamping block on the outside of the spindle sleeve 14 and a clamping member on the spindle clamp 12. The clamping member clamps the clamping block circumferentially to switch between a locked state and a released state. When the locking part 19 is switched to the locked state, the spindle 13 and the spindle clamp 12 are locked and fixedly connected, preventing relative displacement. When the locking part 19 is switched to the released state, the spindle 13 can make a slight movement in a second direction relative to the spindle clamp 12 to adjust the center position of the spindle 13. The locking part 19 provides the prerequisite for adjusting the position of the spindle.

[0082] In this embodiment, the control method in the spindle assembly and circuit board processing equipment includes the following steps:

[0083] S100: The locking part is switched to the released state, and the first connecting part is movably connected to the spindle and the spindle clamp;

[0084] like Figure 7 As shown, the spindle 13 and spindle clamp 12 are slidably connected by the first connecting part 15. The spindle 13 can slide relative to the spindle clamp 12 along the second and third directions on the inclined surface 18 of the first connecting part 15. The top end of the spindle 13 is suspended from the base plate 11 by the second connecting part 16, and the spindle 13 can slide relative to the spindle clamp 12 in the second direction. When the control locking part 19 is switched to the released state, the spindle 13 and the spindle clamp 12 are no longer constrained, but the top end of the spindle 13 is temporarily suspended and constrained by the slider 165 and the slide rail 166 along the second direction, so that the spindle 13 will not move in the third direction due to gravity.

[0085] S200: Control the second connecting part to switch to the locked state. The second connecting part is fixedly connected to the base plate, and the top of the spindle is movably connected to the second connecting part.

[0086] like Figure 7 , Figure 10 As shown, the spindle 13 and spindle clamp 12 are moved upwards along a third direction until the protrusion 162 of the second connecting part 16 slides into the groove 161. At the second connecting part 16, when the control switch is open, the groove 161 clamps the protrusion 162 from the side, restricting the movement of the protrusion 162 and the spindle 13 along the third direction; when the control switch is closed, the groove 161 releases the protrusion 162, allowing the protrusion 162 and the spindle 13 to move along the third direction. After the second connecting part 16 is switched to the locked state, the groove 161 clamps the protrusion 162, restricting the movement of the protrusion 162 and the spindle 13, which is slidably connected to the protrusion 162, along the third direction. Therefore, when the second connecting part 16 is switched to the locked state, the top end of the spindle 13 is suspended on the base plate 11 through the second connecting part 16, restricting the movement of the spindle 13 along the third direction. Of course, the top end of the spindle 13 is slidably connected to the second connecting part 16, allowing the spindle 13 to move relative to the spindle clamp 12 along a second direction.

[0087] S300: The control drive unit drives the spindle clamp to move along a third direction. The spindle moves relative to the third direction on the inclined plane. In the second direction, the inclined plane adjusts the relative position of the spindle and the spindle clamp. The second direction is perpendicular to the third direction.

[0088] like Figure 7 , Figure 10 As shown, the spindle clamp 12 is slidably connected to the base plate 11 via a guide rail along a third direction. The spindle 13 is laterally slidably connected to the spindle clamp 12 via a first connecting part 15. The top end of the spindle 13 is suspended on the base plate 11 via a second connecting part 16 and is slidably connected to the second connecting part 16 along a second direction. When the control drive unit drives the spindle clamp 12 to move upward along a third direction, the spindle 13 cannot follow the spindle clamp 12 along a third direction due to the restriction of the second connecting part 16. Due to the obstruction and squeezing force of the inclined plane 18 on the spindle 13, the spindle 13 moves relative to the spindle clamp 12 along the second and third directions on the inclined plane 18. At this time, the spindle clamp 12 moves along a third direction, and the spindle 13 moves along the second and third directions. In the second direction, the spindle 13 moves relative to the spindle clamp 12. The inclined plane 18 adjusts the relative position of the spindle 13 and the spindle clamp 12, thereby realizing the position adjustment of the spindle 13 in the second direction.

[0089] In this embodiment, before step S300, the method further includes: acquiring the deviation of the spindle 13 in the second direction, and adjusting the relative position of the spindle 13 in the second direction according to the grating ruler on the base plate 11 and the reading head on the spindle clamp 12. The base plate 11 is equipped with a grating ruler, and the spindle clamp 12 is equipped with a reading head. The spindle clamp 12 moves along a third direction on a slide rail on the base plate 11, and the reading head moves relative to the grating ruler, allowing for real-time acquisition of the relative displacement value. Therefore, as... Figure 6As shown, after obtaining the deviation S of the spindle 13 in the second direction, the distance H of the relative movement of the spindle clamp 12 in the third direction is calculated based on the inclination angle ∠A of the inclined surface 18 of the first connecting part 15 and the tangent trigonometric function. Then, based on the reading head and the grating ruler, the actual movement distance of the spindle clamp 12 in the third direction is accurately obtained and adjusted in real time, thereby adjusting the deviation of the spindle 13 in the second direction to a preset range. This ensures that the actual coordinate position of the spindle 13 in the second direction is consistent with the theoretical coordinate position, guaranteeing the consistency of the positions of the two spindle assemblies processing the same circuit board in the second direction; and improving the accuracy of synchronous copy processing of dual spindles.

[0090] Following step S300, the process further includes: controlling the locking part 19 to switch to the locked state, with the spindle 13 fixedly connected to the spindle clamp 12 via the locking part 19. After adjusting the position of the spindle 13 in the second direction, it is necessary to maintain the position of the spindle 13 to ensure machining accuracy. Therefore, controlling the locking part 19 to switch to the locked state, the clamping member of the locking part 19 is controlled to lock the clamping block circumferentially, fixing the clamping block on the clamping member. Through the locking part 19, the spindle 13 is locked on the spindle clamp 12, and the sliding connection between the inclined surface 18 of the first connecting part 15, the slider 165, and the slide rail 166 is locked, preventing relative sliding. No relative displacement in the second or third direction can occur between the spindle 13 and the spindle clamp 12. The spindle 13 is fixedly connected to the spindle clamp 12 via the locking part 19, ensuring that the position of the spindle 13 no longer changes relative to the others.

[0091] This spindle assembly, circuit board processing equipment, and circuit board processing equipment control method can adjust the relative position of the spindle 13 and the spindle clamp 12 in the second direction through the inclined plane 18, thereby achieving fine adjustment of the spindle position. In the second direction, the coordinate positions of multiple spindles that are synchronously copying and processing the same circuit board can be adjusted to be consistent, thereby improving processing efficiency and accuracy of synchronous copying and processing.

[0092] Example 3

[0093] This embodiment uses a circuit board processing equipment with twelve spindle assemblies, where two spindle assemblies simultaneously replicate drilling and processing of a circuit board at one station, as an example to explain in detail the structure of the spindle assembly, the structure of the circuit board processing equipment, and the circuit board processing control method. The difference between this embodiment and Embodiment Two lies in the position of the inclined plane.

[0094] In this embodiment, as Figure 1 , Figure 2As shown, the circuit board processing equipment in this disclosure 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 10 that move along a first direction are slidably mounted on the crossbeam 30 above the worktable 20. The spindle 13 of each spindle assembly 10 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.

[0095] In this embodiment example, such as Figure 2 , Figure 3 , Figure 9 , Figure 11 As shown, the circuit board processing equipment includes: two spindle assemblies 10, which synchronously replicate the same circuit board 22 carried on a worktable. At least one spindle assembly 10 includes: a spindle 13; a first connecting part 15 movably connected to the spindle 13 and a spindle clamp 12; and a second connecting part 16 movably connected to the top end of the spindle 13 and a base plate 11. An inclined surface 18 is provided between the second connecting part 16 and the spindle 13. A control drive unit drives the spindle clamp 12 to move along a third direction, and the spindle 13 moves relative to the third direction along the inclined surface 18. In the second direction, the inclined surface 18 adjusts the relative position of the spindle 13 and the spindle clamp 12. The second and third directions are perpendicular to each other. This circuit board processing equipment can fine-tune the position of the spindle 13 in the second direction to adjust the center position of multiple spindles synchronously replicating the same circuit board to be consistent, thereby improving processing accuracy.

[0096] In this embodiment, as Figure 9 As shown, the spindle assembly 10 includes a base plate 11, a spindle clamp 12, and a spindle 13. The spindle 13 is movably connected to the spindle clamp 12 along a second direction. A drive unit drives the spindle clamp 12 to move along a third direction. The spindle 13 moves relative to the spindle clamp along both the second and third directions on an inclined plane 18. In the second direction, the inclined plane 18 adjusts the relative position of the spindle 13 and the spindle clamp 12. The second direction and the third direction are perpendicular to each other. This spindle assembly 10 is applied to circuit board processing equipment, and the position of the spindle 13 in the second direction can be adjusted to keep the center positions of multiple spindles that are synchronously copying the same circuit board consistent, thereby improving the accuracy of multi-axis synchronous copying processing.

[0097] In this embodiment, as Figure 9 , Figure 11As shown, the first connecting part is movably connected to the spindle and the spindle clamp; the second connecting part is movably connected to the top end of the spindle and the base plate. An inclined surface 18 is disposed between the second connecting part 16 and the top end of the spindle 13. The top end of the spindle 13 is suspended from the base plate 11 via the second connecting part 16. The second connecting part 16 includes a protrusion 162 and a groove, which cooperate to lock or release the spindle. The groove is disposed on the base plate 11, and the protrusion 162 is slidably connected to the top end of the spindle 13. When the control switch is on, the groove laterally clamps the protrusion 162, restricting the movement of the protrusion 162 and the spindle in a third direction; when the control switch is off, the groove releases the protrusion 162, allowing the protrusion 162 and the spindle 13 to move in a third direction. A slider 165 and a slide rail 166 are provided between the top end of the main shaft 13 and the second connecting part 16. The slider 165 is fixedly connected to the protrusion 162 of the second connecting part 16, and the slide rail 166 is fixed to the top end of the main shaft 13. The slide rail 166 extends along a second direction and a third direction. An inclined surface 18 extending along the second direction and a third direction is formed between the slider 165 and the slide rail 166. The slider 165 slides on the slide rail 166, and the main shaft 13 moves relative to each other along the second and third directions on the inclined surface 18, which provides the possibility for micro-motion of the main shaft 13 along the second direction.

[0098] In this embodiment, as Figure 9 As shown, the spindle 13 is laterally connected to the spindle clamp 12 via a first connecting part 15. The first connecting part 15 includes a slider and a slide rail. The slide rail is fixed to the spindle clamp 12, and the slider is fixed to the spindle sleeve 14 on the outside of the spindle 13. The slide rail extends along a second direction, and the slider slides relative to the slide rail. The spindle 13 and the spindle clamp 12 can slide relative to each other along the second direction. The slidable connection between the spindle 13 and the spindle clamp 12 via the first connecting part 15 along the second direction provides the prerequisite for the relative movement of the spindle 13 and the spindle clamp 12.

[0099] like Figure 9 , Figure 11 As shown, the spindle 13 is laterally connected to the spindle clamp 12 via the first connecting part 15 in the second direction. The top end of the spindle 13 is suspended from the base plate 11 via the second connecting part 16. The spindle 13 slides relative to the second and third directions on the inclined surface 18 between the spindle 13 and the second connecting part 16. When the control drive unit drives the spindle clamp 12 to move upward in the third direction on the guide rail of the base plate 11, the spindle 13 moves relative to the spindle clamp 12 in the second and third directions on the inclined surface 18 between the second connecting part 16 and the top end of the spindle 13. Due to the obstruction and squeezing force of the inclined surface 18, the spindle 13 can move relative to the spindle clamp 12 in both the second and third directions simultaneously. In the second direction, the inclined surface 18 adjusts the relative position of the spindle 13 and the spindle clamp 12. Thus, the movement of the spindle clamp 12 in the third direction can be controlled to achieve micro-movement of the spindle 13 in the second direction, thereby achieving the purpose of adjusting the center position of the spindle 13.

[0100] In this embodiment, a locking part 19 is provided laterally between the spindle 13 and the spindle clamp 12. The locking part 19 includes a clamping block on the outside of the spindle and a clamping member on the spindle clamp 12. The clamping member clamps the clamping block circumferentially to switch between a locked state and a released state. When the locking part 19 is switched to the locked state, the spindle 13 and the spindle clamp 12 are locked and fixedly connected, preventing relative displacement. When the locking part 19 is switched to the released state, the spindle 13 can move relative to the spindle clamp 12 in a second direction to adjust the center position of the spindle 13. The locking part 19 provides the prerequisite for adjusting the position of the spindle 13.

[0101] In this embodiment, the control method in the spindle assembly and circuit board processing equipment includes the following steps:

[0102] S100: The locking part is switched to the released state, and the first connecting part is movably connected to the spindle and the spindle clamp;

[0103] like Figure 9 As shown, the spindle 13 and spindle clamp 12 are slidably connected via a first connecting part 15. The spindle 13 can slide laterally relative to the spindle clamp 12 in a second direction. The top end of the spindle 13 is suspended from the base plate 11 via a second connecting part 16. The spindle 13 slides relative to the spindle clamp 12 in both the second and third directions on the inclined surface 18 between the spindle 13 and the second connecting part 16. When the control locking part 19 switches to the released state, the spindle 13 and spindle clamp 12 are no longer constrained, but the spindle 13 is temporarily suspended and constrained laterally via the first connecting part 15, preventing the spindle 13 from moving in a third direction due to gravity.

[0104] S200: Control the second connecting part to switch to the locked state. The second connecting part is fixedly connected to the base plate, and the top of the spindle is movably connected to the second connecting part.

[0105] like Figure 9 , Figure 11 As shown, the spindle 13 and spindle clamp 12 move upwards along a third direction until the protrusion 162 of the second connecting part 16 slides into the groove 161. At the second connecting part 16, when the control switch is open, the groove clamps the protrusion 162 from the side, restricting the movement of the protrusion 162 and the spindle 13 along a third direction; when the control switch is closed, the groove releases the protrusion 162, allowing the protrusion 162 and the spindle 13 to move along a third direction. After the second connecting part 16 is switched to the locked state, the groove clamps the protrusion 162, restricting the movement of the protrusion 162 and the spindle 13 slidably connected to the protrusion along a third direction. Therefore, when the second connecting part 16 is switched to the locked state, the top end of the spindle 13 is suspended on the base plate 11 through the second connecting part 16, restricting the movement of the spindle 13 along a third direction.

[0106] S300: The control drive unit drives the spindle clamp to move along a third direction. The spindle moves relative to the third direction on the inclined plane. In the second direction, the inclined plane adjusts the relative position of the spindle and the spindle clamp. The second direction is perpendicular to the third direction.

[0107] In this embodiment, as Figure 9 , Figure 11 As shown, the spindle clamp 12 moves along a third direction on the slide rail of the base plate 11. The spindle 13 is laterally slidably connected to the spindle clamp 12 via the first connecting part 15. The top end of the spindle 13 is suspended on the base plate 11 via the second connecting part 16 and is slidably connected to the second connecting part 16 along the second direction and the third direction. When the control drive unit drives the spindle clamp 12 to move upward along the third direction, the spindle 13 cannot follow the spindle clamp 12 along the third direction due to the restriction of the second connecting part 16. Due to the obstruction and squeezing force of the inclined plane 18 on the spindle 13, the spindle 13 moves relative to the spindle clamp 12 along the second direction and the third direction on the inclined plane 18. At this time, the spindle clamp 12 moves along the third direction, and the spindle 13 moves along the second direction and the third direction. In the second direction, the spindle 13 moves relative to the spindle clamp 12. The inclined plane 18 adjusts the relative position of the spindle 13 and the spindle clamp 12, thereby realizing the position adjustment of the spindle 13 in the second direction.

[0108] In this embodiment, before step S300, the method further includes: acquiring the deviation of the spindle in the second direction, and adjusting the relative position of the spindle in the second direction according to the grating ruler on the base plate and the reading head on the spindle clamp. A grating ruler is provided on the base plate 11, and a reading head is provided on the spindle clamp 12. The spindle clamp 12 moves along a third direction on a slide rail on the base plate 11, and the reading head moves relative to the grating ruler, allowing for real-time acquisition of the relative displacement value. Therefore, as... Figure 6 As shown, after obtaining the deviation S of spindle 13 in the second direction, the distance H of the relative movement of spindle clamp 12 in the third direction is calculated and determined based on the tilt angle ∠A of inclined plane 18 and the tangent trigonometric function. Then, based on the reading head and grating ruler, the movement distance of spindle clamp 12 in the third direction is accurately obtained and adjusted, thereby adjusting the deviation of spindle 13 in the second direction to a preset range. This ensures that the actual coordinate position of spindle 13 in the second direction is consistent with the theoretical coordinate position, guaranteeing the consistency of the positions of the two spindle assemblies processing the same circuit board in the second direction; and improving the accuracy of synchronous copy processing of dual spindles.

[0109] Following step S300, the process further includes: controlling the locking part to switch to the locked state, with the spindle fixedly connected to the spindle clamp via the locking part 19. After adjusting the position of the spindle 13 in the second direction, it is necessary to maintain the position of the spindle 13 to ensure machining accuracy. Therefore, the locking part 19 is switched to the locked state, and the clamping member of the locking part 19 locks the clamping block circumferentially, fixing the clamping block to the clamping member. Through the locking part 19, the spindle 13 is locked on the spindle clamp 12, and the sliding connection between the first connecting part 15 and the inclined surface 18 is locked, preventing relative sliding. The spindle 13 and the spindle clamp 12 cannot experience relative displacement in the second and third directions. The spindle 13 is fixedly connected to the spindle clamp 12 via the locking part 19 and the first connecting part 15, ensuring that the position of the spindle 13 no longer changes relative to the others.

[0110] This spindle assembly, circuit board processing equipment, and circuit board processing equipment control method can adjust the relative position of the spindle 13 and the spindle clamp 12 in the second direction through the inclined plane 18, thereby achieving fine adjustment of the position of the spindle 13. In the second direction, the coordinate positions of the two spindles that are synchronously copying and processing the same circuit board can be adjusted to be consistent, thereby improving processing efficiency and accuracy of synchronous copying and processing.

[0111] Example 4

[0112] This embodiment uses a circuit board processing equipment with twelve spindle assemblies, where two spindle assemblies synchronously replicate drilling and processing of a circuit board at one station, to illustrate in detail the structure of the spindle assembly, the structure of the circuit board processing equipment, and the circuit board processing control method.

[0113] In this embodiment, as Figure 8 As shown, the difference from Embodiment 2 is that the spindle clamp 12 is provided with an inclined surface 18, which extends along the second and third directions. The spindle clamp 12 is connected to the outer spindle sleeve 14 of the spindle 13 through the first connecting part 15. Other structures are basically the same as those in Embodiment 2 or have been adapted accordingly.

[0114] Specifically, the first connecting part 15 includes a slider and a slide rail. A parallel guide rail is provided on the inclined surface 18 of the spindle clamp 12, and an inclined slider is provided on the spindle sleeve 14 of the spindle 13. The slider moves on the slide rail, causing the spindle 13 to move relative to the spindle clamp 12 along the second and third directions on the inclined surface 18 of the spindle clamp. The sliding connection between the inclined surface 18 of the spindle clamp and the first connecting part provides the precondition for the relative micro-motion of the spindle 13 and the spindle clamp 12.

[0115] In this embodiment, as Figure 8 and Figure 10As shown, the structure of the second connecting part 16 is the same as in Embodiment 2. The top end of the main shaft 13 is suspended on the base plate 11. Due to the sliding connection between the slider 165 and the slide rail 166, the main shaft 13 can move relative to the main shaft clamp 12 in the second direction. When the control drive unit drives the main shaft clamp 12 to move upward in the third direction on the guide rail of the base plate 11, the main shaft 13 moves relative to the main shaft clamp 12 in the second and third directions on the inclined surface 18 of the main shaft clamp 12. Due to the blocking and squeezing force of the inclined surface 18, the main shaft 13 can move relative to the main shaft clamp 12 in the second and third directions. At this time, the main shaft clamp 12 moves in the third direction, and the main shaft 13 moves in the second and third directions. In the second direction, the main shaft 13 moves relative to the main shaft clamp 12, and the inclined surface 18 adjusts the relative position of the main shaft 13 and the main shaft clamp 12. Thus, the movement of the main shaft clamp 12 in the third direction can be controlled to achieve micro-movement of the position of the main shaft 13 in the second direction, thereby achieving the purpose of adjusting the center position of the main shaft.

[0116] In this embodiment, the control method for the circuit board processing equipment is the same as in Embodiment 2, and will not be repeated here. In this embodiment, the spindle assembly, circuit board processing equipment, and control method can adjust the relative positions of the spindle 13 and spindle clamp 12 in the second direction via the inclined plane 18, achieving fine-tuning of the spindle 13 position. In the second direction, the coordinate positions of the two spindles synchronously copying the same circuit board can be adjusted to maintain consistency, improving processing efficiency while also increasing the accuracy of synchronous copying processing.
