[0034] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Reference Figures 1 to 5 As shown, the present invention provides a circuit board processing equipment, including a spindle clamping assembly 10, a spindle 20, a guide mechanism 30, and a position measuring assembly 40, wherein:

[0036] The spindle clamp assembly 10 includes a spindle clamp bracket 11, a spindle clamp 12, and a support member 14. The spindle clamp bracket 11 serves as a mounting base. The spindle clamp 12 and the support member 14 are both independently distributed on the spindle clamp bracket 11. The support member 14 and the spindle clamp 12 are two independent structures. The spindle clamp 12 is used to fix or release the spindle 20, and the support member 14 is used to provide a mounting base for the position measurement assembly 40. Under the action of external force, the spindle clamp bracket 11 can reciprocate linearly along a preset path direction to drive the components mounted on the spindle clamp bracket 11 to move together. The extension direction of this preset path is consistent with the axial direction of the spindle 20.

[0037] In one feasible embodiment, the spindle clamp bracket 11 is a plate structure, and the spindle clamp 12 includes a stationary block and a movable block. The stationary block is fixed on the spindle clamp bracket 11, and the movable block is detachably fixed on the stationary block. After the movable block and the stationary block are combined and fixed, an installation cavity is formed inside the spindle clamp 12 for fixing the spindle 20. After the movable block and the stationary block are separated, the spindle 20 can be disassembled. By adjusting the posture of the movable block fixed on the stationary block, the axial direction of the spindle 20 can be adjusted so that the spindle 20 is perpendicular to the circuit board.

[0038] The spindle 20 is fixed inside the spindle clamp 12, which applies radial force to clamp it. The spindle 20 must withstand the radial force applied by the spindle clamp 12, i.e., the clamping force.

[0039] The guide mechanism 30 is mounted on the spindle clamp assembly 10 and is offset from the spindle clamp 12 to facilitate the maintenance of the spindle 20. The guide mechanism 30 includes a drive member 31 and a guide member 32. One end of the drive member 31 is connected to the guide member 32 to drive the guide member 32 to reciprocate along the axial direction of the spindle 20. The other end of the guide member 32 is connected to a chip suction hood assembly 50. The chip suction hood assembly 50 is located between the spindle 20 and the circuit board. Under the action of the drive member 31, the chip suction hood assembly 50 reciprocates along the axial direction of the spindle 20.

[0040] Initially, the chip suction hood assembly 50 is a certain distance from the circuit board. During circuit board processing, the drive unit 31 drives the chip suction hood assembly 50 to the processing position. The spindle clamp 11 is driven by external force to perform a reciprocating motion of lowering and raising. The chip suction hood assembly 50 and other parts such as the spindle 20 are relatively stationary with respect to the spindle clamp 11 and move together with it. During drilling, the spindle clamp 11 moves downward. After the chip suction hood assembly 50 contacts the surface of the circuit board, it is blocked and restricted from moving downward. When the spindle clamp 11 continues to move downward, the chip suction hood assembly 50 presses against the surface of the circuit board. The spindle 20 drives the drill bit to rotate and drill. Then, the spindle clamp 11 is driven upward by external force, and the chip suction hood assembly 50 separates from the surface of the circuit board.

[0041] Reference Figure 4 as well as Figure 5 As shown, the position measurement assembly 40 includes a first sensing element 41 and a second sensing element 42. The first sensing element 41 and the second sensing element 42 cooperate to measure the movement distance of the spindle 20. Specifically, the first sensing element 41 is used to sense the position of the second sensing element 42. One of the first sensing element 41 and the second sensing element 42 is disposed on the guide member 32, and the other is disposed on the support member 14. In one feasible embodiment, the first sensing element 41 is disposed on the support member 14, and the second sensing element 42 is disposed on the guide member 32. During the drilling process, the second sensing element 42 remains stationary, and the first sensing element 41 moves with the spindle 20. The positions of the first sensing element 41 and the second sensing element 42 can be interchanged. As long as one of the first sensing element 41 and the second sensing element 42 remains stationary, and the other moves up and down with the spindle 20, the movement distance (i.e., machining depth) of the spindle 20 can be measured.

[0042] The first sensing element 41 and the second sensing element 42 are not located on the spindle clamp 12 or the chip suction hood assembly 50, but are respectively located on the guide 32 and the support 14. They measure the movement distance of the spindle 20 in real time, which can improve the reliability and stability of the position measurement assembly 40, thereby enabling higher frequency machining operations, improving machining efficiency, and facilitating the maintenance of the spindle 20 and the position measurement assembly 40.

[0043] In the embodiments provided by the present invention, reference is made to Figure 5 As shown, the guide member 32 includes a first plate 321, a second plate 322, a transition plate 323, and a guide rod 324, wherein:

[0044] Along the axial direction of the main shaft 20, the first plate 321 and the second plate 322 are respectively disposed on opposite sides of the support member 14. The first plate 321 is connected to the drive member 31, and the second plate 322 is connected to the chip suction hood assembly 50.

[0045] Multiple guide rods 324 are provided, and the opposite ends of the multiple guide rods 324 are respectively connected to the first plate 321 and the second plate 322. The support member 14 and / or the spindle clamp bracket 11 are provided with guide holes 15. The guide holes 15 are set away from the spindle clamp 12. The extension direction of the guide holes 15 is parallel to the axial direction of the spindle 20. The guide rods 324 are guided and fitted into the guide holes 15.

[0046] The first plate 321, the second plate 322, and the guide rods 324 are formed in a single rigid structure. The driving component 31 applies force to the first plate 321 instead of directly to each guide rod 324, thereby avoiding asynchronous displacement of multiple guide rods 324 during the lifting and lowering process of the guide component 32, which would affect the control accuracy of the machining depth.

[0047] The two ends of the adapter plate 323 are respectively connected to the first plate 321 and the second plate 322. The first sensing element 41 or the second sensing element 42 is disposed on the adapter plate 323. The adapter plate 323 is also rigidly connected to the first plate 321 and the second plate 322. This can improve the overall strength of the guide 32. During the processing, since the chip suction hood assembly 50 is in a compressed state, the guide 32 will not generate related vibration offset, which makes the stability of the second sensing element 42 better and reduces the impact of the deformation of the guide 32 on the processing accuracy. This can improve the reliability and stability of the position measurement assembly 40, thereby improving the processing efficiency.

[0048] In one feasible implementation method, refer to Figure 4 As shown and Figure 5As shown, the first sensing element 41 is mounted on the support member 14, and the second sensing element 42 is mounted on the adapter plate 323. When processing the circuit board, the spindle clamp 11 moves downward, and the chip suction hood assembly 50 is blocked and restricted from moving downward after contacting the surface of the circuit board. When the spindle clamp 11 continues to move downward, the first sensing element 41 moves synchronously with the spindle 20, the guide member 32 remains stationary relative to the circuit board, and the second sensing element 42 remains stationary, thereby measuring the processing depth of the spindle 20. The chip suction hood assembly 50 presses against the surface of the circuit board, the spindle 20 drives the drill bit to rotate and drill, and then changes position to drill. The spindle clamp 11 is driven upward by external force, and the chip suction hood assembly 50 separates from the surface of the circuit board.

[0049] Preferably, refer to Figure 5 As shown, there are three guide rods 324, which are parallel to each other. The line connecting the centers of the axes of the three guide rods 324 forms an isosceles triangle or an equilateral triangle. The three guide members 32 are distributed at the three vertices of the triangle, resulting in high structural stability. The first plate 321 and the second plate 322 are connected by the three evenly distributed guide rods 324 to form a rigid body. When the first plate 321 is subjected to the force applied by the guide member 32, the force is evenly distributed and transmitted to the second plate 322 through the three guide rods 324. Under the high-speed and high-frequency movement of the spindle clamp 11, the guide member 32 can still maintain high rigidity, preventing the first plate 321 or the second plate 322 from deforming, which would cause the position of the second sensing element 42 to change and affect the measurement accuracy of the position measurement component 40.

[0050] Those skilled in the art will know that the number of guide rods 324 can be set to more, and their distribution can also be determined according to the actual situation, such as four, five or more, etc., which are not limited here.

[0051] In existing technologies, the guide hole is located on the spindle clamp. Because the spindle's perpendicularity needs frequent maintenance, the tightness of the screws on the spindle clamp must be adjusted to ensure the spindle's perpendicularity. This necessitates adjustments to the position measurement assembly, increasing the complexity and workload of maintaining both the spindle and the position measurement assembly.

[0052] Therefore, in the embodiments provided by the present invention, the guide hole 15 is not provided on the spindle clamp 12, and the guide rod 324 is separated from the spindle clamp 12, as shown in the reference. Figure 1 as well as Figure 5As shown, the spindle clamp bracket 11 has guide bosses 13 protruding on opposite sides of the spindle clamp 12. Each of the two guide bosses 13 has a guide hole 15 through it. The support member 14 has a guide hole 15 for the guide rod 324 to pass through. The three guide holes 15 correspond to the three guide rods 324. Preferably, the line connecting the centers of the three guide holes 15 is an isosceles triangle or an equilateral triangle, so that when the spindle 20 is maintaining the tightness of the screws, it will not affect the position measuring component 40. This facilitates the assembly and maintenance of the spindle 20 and the position measuring component 40, and reduces the tediousness and workload of customer maintenance.

[0053] Preferably, a linear bearing is embedded in each guide hole 15, and the guide rod 324 passes through the linear bearing, thereby further improving the stability and synchronicity of the guide rod 324 in linear movement, while reducing the influence of friction and preventing deformation of the guide rod 324 during movement.

[0054] In one feasible implementation, refer to Figure 5 As shown, the support member 14 includes a first support block 141, a second support block 142, and a first connecting block 143. The first support block 141, the second support block 142, and the first connecting block 143 are preferably integrally formed to improve the overall strength. There are two first support blocks 141 and two first connecting blocks 143. The second support block 142 is provided with a guide hole 15. The two opposite ends of the second support block 142 are respectively connected to the first connecting block 143. The first connecting block 143 is connected to the first support block 141. The two first support blocks 141 are parallel to each other. The first connecting block 143 intersects the first support block 141 and the second support block 142 at an incline. The first support block 141 is detachably connected to the side end of the guide boss 13 by bolts. The first sensing element 41 or the second sensing element 42 is provided on the side end of the second support block 142.

[0055] The first support block 141, the second support block 142, and the first connecting block 143 are all located on the outer periphery of the spindle clamp 12. The inner wall surfaces of the first support block 141, the second support block 142, and the first connecting block 143 form a receiving space with the surface of the spindle clamp bracket 11. The spindle clamp 12 is located in this receiving space. The support member 14 is separated from the spindle clamp 12. The movement of the spindle clamp 12 and the spindle 20 will not affect the guide member 32 that moves on the support member 14 and the guide boss 13. When adjusting the clamping state of the spindle clamp 12 and during the rotation drilling process of the drill bit of the spindle 20, the position and posture of the guide rod 324 will not be affected.

[0056] In one feasible implementation, refer to Figure 5As shown, the first plate 321 includes a first front plate 3211, a first connecting plate 3212, and a first rear plate 3213. The first front plate 3211, the first connecting plate 3212, and the first rear plate 3213 are preferably integrally formed to improve overall strength. Two first front plates 3211 and two first connecting plates 3212 are provided. The opposite ends of the first front plate 3211 are respectively connected to the first connecting plate 3212. The first connecting plate 3212 is connected to the first rear plate 3213. The two first rear plates 3211... The 13 plates are parallel to each other. The first connecting plate 3212 intersects the first front plate 3211 and the second front plate at an incline. The first front plate 3211 and the two first rear plates 3213 are each connected to a guide rod 324. The connection points of the guide rods 324 and the first plate 321 are distributed at the ends of the first plate 321. After the first plate 321 is subjected to the force of the driving member 31, it can be distributed to the three guide rods 324 to prevent the guide member 32 from deforming during the movement and affecting the measurement accuracy of the position measuring component 40.

[0057] In one feasible implementation, refer to Figure 5 As shown, the second board body 322 includes a main board body 3221. A through hole is provided on the surface of the main board body 3221. The through hole is used for the drill bit of the spindle 20 to pass through in order to avoid interference. The chip suction cover assembly 50 is configured to cover the drill bit of the spindle 20 so that the chips generated by the drill bit of the spindle 20 during the drilling process can be blocked by the chip suction cover assembly 50, thereby preventing the chips from being thrown outside the circuit board processing equipment.

[0058] Three lugs 3222 are arranged in a ring on the outer circumferential surface of the main board body 3221. One lug 3222 is corresponding to the first front plate body 3211, and the other two lugs 3222 are respectively corresponding to the two first rear plates 3213. The adapter plate body 323 is connected to the lugs 3222 and the first front plate body 3211 respectively. The connection between the guide rod 324 and the second plate body 322 is distributed on the second plate body 322. After the second plate body 322 is subjected to a uniform force, the chip suction cover assembly 50 can better adhere to and press the surface of the circuit board.

[0059] In the embodiments provided by this invention, the driving component 31 includes two driving cylinders, which are symmetrically arranged on opposite sides of the spindle clamp 12. The cylinder bodies of the driving cylinders are fixed on the spindle clamp bracket 11. The two driving cylinders correspond one-to-one with the two first rear plates 3213. The piston rod ends of the driving cylinders are connected to the first rear plates 3213. Under the action of working air pressure, the driving cylinders extend the piston rods downwards. Subsequently, the spindle clamp bracket 11 and all components mounted on it (including the spindle clamp 12, spindle 20, etc.) move downwards under the action of external force. The spindle moves until the chip suction hood assembly 50 presses against the circuit board for processing. The external force further drives the spindle clamp 11 to move further to overcome the pressure of the drive cylinder, causing the piston rod to be gradually pressed back. The drill bit at the front end of the spindle 20 gradually extends beyond the chip suction hood assembly 50 to achieve drilling. After drilling to the required depth, the chip suction hood assembly 50 rises under the action of external force, and the piston rod of the drive cylinder gradually extends outward until it is fully extended, so that the chip suction hood assembly 50 rises with the spindle clamp 11 and detaches from the circuit board surface, thus completing one drilling cycle.

[0060] In one feasible implementation, refer to Figure 3 as well as Figure 4 As shown, the first sensing element 41 is a magnetic scale, and the second sensing element 42 is a reading head that cooperates with the magnetic scale. The magnetic scale is located on the support 14, and the reading head is located on the adapter plate 323 of the guide 32. When processing the circuit board, the spindle clamp 11 moves down, and the chip suction hood assembly 50 is blocked and restricted from moving downward after contacting the surface of the circuit board. When the spindle clamp 11 continues to move down, the magnetic scale moves synchronously with the spindle 20, and the reading head remains stationary. The reading head reads the numerical change on the magnetic scale, thereby feeding back the numerical information to the controller, thereby measuring the processing depth of the spindle 20. The chip suction hood assembly 50 presses against the surface of the circuit board, and the spindle 20 drives the drill bit to rotate and drill. Then, the drill bit is rotated and repositioned. The spindle clamp 11 is driven upward by external force, and the chip suction hood assembly 50 separates from the surface of the circuit board.

[0061] Those skilled in the art will know that the first sensing element 41 can also be other measuring elements such as a grating ruler, and the positions of the first sensing element 41 and the second sensing element 42 can also be interchanged, without limitation.

[0062] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
