Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0050] In PCB (Printed Circuit Board) drilling, the automated rotation of the cutter head (also known as the drill bit magazine) is a key technology for achieving efficient and continuous production. Its core lies in using an intelligent system to automatically change, calibrate, and manage the lifespan of drill bits, thereby improving equipment uptime and efficiency. The inventors discovered that the frequent opening and closing of the cutter head box and the drilling rig's worktable still requires maintaining the cutter head's positional accuracy and stability. Using magnetic adsorption to fix the cutter head also necessitates considering the uneven suction caused by variations in the contact surface due to the cutter head's consistency.

[0051] In view of this, this application provides a cutter head fixing device 100, which can be applied to circuit board processing equipment 10 such as drilling machines to accurately and stably fix the cutter head 200, thereby meeting the automated flow requirements of the cutter head 200 and improving the utilization rate and efficiency of equipment production.

[0052] Please see Figures 1 to 6 The cutter head fixing device 100 of this application embodiment includes a support member 110 and a first magnetic adsorption assembly 130. The support member 110 is used to support the cutter head 200 and has a limiting hole 112 thereon. The first magnetic adsorption assembly 130 includes a magnetic member 131 and a connecting member 132 connected to each other. The magnetic member 131 is used to adsorb the cutter head 200, and the connecting member 132 passes through the limiting hole 112. The connecting member 132 is used to movably install the magnetic member 131 on the support member 110.

[0053] Specifically, please refer to Figure 1 In one embodiment of this application, the cutter head fixing device 100 includes: a support member 110, a first magnetic adsorption component 130, and an elastic member 140.

[0054] The support member 110 is used to support the cutter head 200. It is generally configured as a plate structure. The cutter head 200 can be placed on the support member 110, thereby supporting the cutter head 200 through the support member 110.

[0055] The support member 110 includes a mounting base 111, which is disposed on the main body 120 of the support member 110. The mounting base 111 can be integrally formed with the main body 120, meaning the mounting base 111 and the main body 120 are a single integrated structure, which can be manufactured using a one-piece molding process. Alternatively, the mounting base 111 and the main body 120 can be separate structures, installed on the main body 120 via bolts, snap-fit ​​connections, or plug-in joints. For example... Figure 5 As shown, mounting base 111 is provided with mounting hole 119. Screws are passed through mounting hole 119 and connected to main body 120 to mount mounting base 111 on main body 120.

[0056] Optionally, please refer to [the relevant document / reference]. Figure 1 The support member 110 includes a first step structure 121, a second step structure 122, and a main body 120. The first step structure 121 and the second step structure 122 are respectively connected to the two sides of the main body 120 and protrude upward relative to the main body 120 to support the cutter head 200. The mounting base 111 is connected to the main body 120 and is mounted on the lower part of the main body 120.

[0057] Please combine them together Figure 2 , Figure 3 and Figure 4 The mounting base 111 is used to mount the first magnetic adsorption assembly 130 and the elastic element 140. Specifically, the mounting base 111 is provided with a limiting hole 112, and the elastic element 140 is disposed within the limiting hole 112. The first magnetic adsorption assembly 130 is movably disposed on the mounting base 111, that is, the first magnetic adsorption assembly 130 is mounted on the mounting base 111 in a movable manner, for example, it can be assembled by a sliding fit.

[0058] The first magnetic adsorption component 130 is used to adsorb the cutter head 200. It can be configured to be magnetic (e.g., a magnet or electromagnet), attracting a structure on the cutter head 200 that responds to magnetic force (e.g., a magnet, iron, etc.) to adsorb the cutter head 200. Alternatively, the first magnetic adsorption component 130 can also be configured to respond to magnetic force, achieving adsorption by cooperating with the magnetic structure on the cutter head 200. The first magnetic adsorption component 130 is configured to move towards the cutter head 200 due to mutual magnetic adsorption with it.

[0059] The first magnetic adsorption assembly 130 includes a magnetic component 131 and a connector 132 connected together. The connector 132 passes through a limiting hole 112 and contacts an elastic component 140. The magnetic component 131 is a component capable of generating magnetic force, such as a magnet or an electromagnet. The connector 132 is connected to the magnetic component 131 and passes through the limiting hole 112, so that when the first magnetic adsorption assembly 130 moves relative to the mounting base 111, the hole wall 114 of the limiting hole 112 can guide the connector 132, allowing the connector 132 and the magnetic component 131 to move stably along the axial direction (height direction Z in this embodiment) of the limiting hole 112.

[0060] The elastic element 140 contacts the mounting base 111 and the first magnetic adsorption assembly 130. The elastic element 140 applies an elastic force opposite to the direction of the magnetic force to the first magnetic adsorption assembly 130. Specifically, the connecting member 132 contacts the elastic element 140, so that when the magnetic member 131 moves toward the cutter head 200, the elastic element 140 can apply an elastic force opposite to the magnetic force to the connecting member 132, constraining the connecting member 132 and the magnetic member 131, automatically adjusting the distance between the magnetic member 131 and the cutter head 200, thereby allowing the magnetic member 131 to stably and accurately adsorb the cutter head 200.

[0061] Please see Figure 3 and Figure 4 The connector 132 includes a rod portion 134 and a limiting portion 133. The rod portion 134 is connected to the magnetic component 131, and the limiting portion 133 is connected to the end of the rod portion 134 away from the magnetic component 131. Optionally, the connector 132 can adopt a screw structure (e.g., a shoulder screw), with the screw head serving as the limiting portion 133. The elastic component 140 is a spring, sleeved on the rod portion 134. The front end of the rod portion 134 is threaded, allowing the front end of the rod portion 134 to be connected to the magnetic component 131 via the thread. The wall 114 of the limiting hole 112 is provided with a limiting step 113, located between the limiting portion 133 and the magnetic component 131. The elastic component 140 is disposed between the limiting portion 133 and the limiting step 113, with one end of the elastic component 140 abutting against the limiting step 113 and the other end abutting against the limiting portion 133. When the magnetic component 131 moves under the magnetic force of the cutter head 200, the magnetic component 131 can drive the connecting component 132 to move, so that the limiting part 133 and the limiting step 113 move closer to each other, squeezing the elastic component 140 to produce elastic deformation. Thus, the elastic component 140 can provide an elastic force opposite to the magnetic force, forming a constraint and automatically adjusting the distance between the magnetic component 131 and the cutter head 200.

[0062] In other embodiments, the limiting step 113 may be located on the side of the connector 132 away from the magnetic component 131. One end of the elastic component 140 is fixedly connected to the connector 132, and the other end is fixedly connected to the limiting step 113. When the magnetic component 131 moves under the magnetic force of the cutter head 200, the magnetic component 131 can drive the connector 132 to move, so that the connector 132 and the limiting step 113 move away from each other, stretching the elastic component 140 to produce elastic deformation. Thus, the elastic component 140 can provide an elastic force opposite to the magnetic force, forming a constraint and automatically adjusting the distance between the magnetic component 131 and the cutter head 200.

[0063] Therefore, in the cutter head fixing device 100 of the above embodiment, by movably setting the first magnetic adsorption component 130 on the mounting base 111 and cooperating with the elastic element 140 that applies a reverse elastic force, a dynamic balance system can be constructed: when the cutter head 200 approaches, the magnetic force drives the first magnetic adsorption component 130 to move towards the cutter head 200, while the elastic element 140 forms a constraint through the reverse elastic force. The interaction between the two causes the first magnetic adsorption component 130 to automatically adjust the distance between itself and the cutter head 200 during the movement, effectively compensating for the gap error caused by machining and assembly tolerances. For different cutter heads 200, a relatively suitable magnetic adsorption distance can be maintained continuously, and the cutter head 200 and the first magnetic adsorption component 130 can be directly contacted and completely adsorbed, thereby significantly improving the positional accuracy, stability and reliability of the cutter head 200 adsorption, and thus contributing to the automated circulation of the cutter head 200.

[0064] Please refer to it again. Figure 4 In some embodiments, the limiting hole 112 extends in the height direction Z, and the mounting base 111 is also provided with a receiving groove 115 communicating with the limiting hole 112. The receiving groove 115 is disposed above the limiting hole 112, and at least a portion of the magnetic component 131 is disposed within the receiving groove 115. In this way, the magnetic component 131 can be accommodated by the receiving groove 115, and the sidewall of the receiving groove 115 can guide the magnetic component 131, making the movement of the magnetic component 131 more stable.

[0065] Please see Figure 5 In some embodiments, the mounting base 111 is further provided with a threaded hole 117, which extends in the height direction Z and communicates with the receiving groove 115. An adjusting screw 118 is provided within the threaded hole 117, protruding into the receiving groove 115 to adjust the position of the magnetic component 131 in the height direction Z. By turning the adjusting screw 118, its protrusion height into the receiving groove 115 can be changed, thereby allowing the magnetic component 131 to be pressed against the target position, enabling it to be completely attracted to the cutter head 200 and improving the stability of the attraction.

[0066] Optionally, the mounting base 111 is provided with multiple threaded holes 117, which are distributed circumferentially along the limiting hole 112. Thus, in the circumferential direction, the position of the magnetic component 131 can be adjusted by multiple adjusting screws 118, so that the upper surface of the magnetic component 131 can be kept horizontal, further improving the stability of adsorption.

[0067] Please refer to it again. Figures 1 to 4The mounting base 111 is also provided with a side groove 116 communicating with the receiving groove 115, and the side groove 116 can expose at least part of the magnetic component 131. In conjunction with the above embodiment with adjusting screw 118, the position of the magnetic component 131 can be observed and adjusted through the side groove 116, so as to facilitate the accurate adjustment of the magnetic component 131 to the target height position.

[0068] Please refer to it again. Figure 1 The mounting base 111 is connected to the side of the main body 120 facing away from the cutter head 200. The main body 120 of the support member 110 is provided with a clearance hole 123, which corresponds to the receiving groove 115 in the height direction Z. By providing the clearance hole 123, the obstruction of the first magnetic adsorption component 130 by the support member 110 can be reduced, the influence on the magnetic force can be reduced, and the adsorption effect can be improved. Furthermore, by providing the clearance hole 123, when the cutter head 200 is placed on the support member 110, the first magnetic adsorption component 130 moves closer to the cutter head 200, and its magnetic component 131 can at least partially move into the clearance hole 123. The clearance hole 123 guides the magnetic component 131, ensuring the stability of the movement and improving the adsorption effect.

[0069] In some embodiments, the cutter head fixing device 100 includes a plurality of mounting seats 111, a plurality of first magnetic adsorption components 130 and a plurality of elastic elements 140. The mounting seats 111, the first magnetic adsorption components 130 and the elastic elements 140 are arranged in a one-to-one correspondence, and the cutter head 200 can be adsorbed by multiple positions, thereby further improving the stability of adsorption and the accuracy of position.

[0070] Please see Figure 6 In another embodiment of this application, the cutter head fixing device 100 may not include the aforementioned elastic element 140. Its magnetic element 131 is connected to a connecting element 132, which is a screw. By tightening the connecting element 132, the magnetic element 131 can be fixed to the mounting base 111; by loosening the connecting element 132, the magnetic element 131 can move relative to the mounting base 111. In this embodiment, the mounting base 111 also has a threaded hole 117 extending in the height direction Z. An adjusting screw 118 is provided inside the threaded hole 117. By rotating the adjusting screw 118, the magnetic element 131 can be pushed, thereby adjusting the height of the magnetic element 131 so that its adsorption surface 135 can be adjusted to a suitable position relative to the cutter head 200, ensuring the stability of the adsorption. Specifically, the threaded hole 117 extends in the height direction Z and communicates with the receiving groove 115. By rotating the adjusting screw 118, it can protrude into the receiving groove 115 to push the magnetic component 131, thereby pressing the magnetic component 131 at the target position so that it can be completely attracted to the cutter head 200, thus improving the stability of the attraction.

[0071] It should be noted that in the above embodiments, the mounting base 111 can be an independent component of the support member 110, and can be installed on the main body 120 of the support member 110 by means of screws, welding, adhesive, etc. Alternatively, the support member 110 can be set as an integral structure, with the mounting base 111, the main body 120, the first step structure 121, and the second step structure 122 being integral parts of the same structure. Alternatively, in the above embodiments, the various structures of the mounting base 111 are directly formed on the main body 120, that is, any one or more of the above-mentioned limiting hole 112, limiting step 113, receiving groove 115, side groove 116, threaded hole, and adjusting screw 118 can be directly provided on the main body 120.

[0072] Accordingly, this application also provides a circuit board processing device 10, which can be a drilling machine, a depaneling machine, or other equipment used for processing circuit boards. Figure 7 As shown, the circuit board processing equipment 10 includes: a worktable 300, a cutter head fixing device 100 according to any embodiment of this application, and a cutter head 200. The cutter head fixing device 100 is disposed on the worktable 300, and the cutter head 200 can be disposed on the support member 110 of the cutter head fixing device 100 and is fixed by adsorption by the first magnetic adsorption component 130.

[0073] It should be noted that the worktable 300 is the core support platform of the circuit board processing equipment 10. Its main functions include: providing a stable support reference surface for the circuit board; achieving precise positioning and rigid fixation of the board through vacuum adsorption, mechanical clamps, or magnetic fixation to ensure no displacement during processing. The worktable 300 integrates high-precision guide rails or servo systems, working in conjunction with the processing tools to complete multi-axis linkage control, achieving micron-level positioning for processes such as drilling and cutting. Some worktables 300 also have temperature compensation, vibration reduction and noise reduction, or automatic leveling functions to eliminate environmental interference and improve processing accuracy and consistency. The tool turret 200 is used to house different types of tools, facilitating the machining spindle to retrieve tools from the tool turret 200.

[0074] Please see Figure 8In some embodiments, the cutter head 200 has a second magnetic adsorption component 210 on the side facing the cutter head fixing device 100. The second magnetic adsorption component 210 is used to apply magnetic force to the first magnetic adsorption component 130. As described above, at least one of the second magnetic adsorption component 210 and the first magnetic adsorption component 130 can generate magnetism, and the other can respond to magnetism, so that the two can cooperate to adsorb. Optionally, the first magnetic adsorption component 130 includes an electromagnet, and the second magnetic adsorption component 210 includes a plate-like structure made of steel or other metal materials that can be attracted by an electromagnet. When the cutter head 200 is adsorbed and fixed on the cutter head fixing device 100, the second magnetic adsorption component 210 and the first magnetic adsorption component 130 are positioned correspondingly in the height direction Z, so that the two can be accurately adsorbed into place.

[0075] Please refer to it again. Figure 8 The cutter head 200 has multiple second magnetic adsorption components 210, and the cutter head fixing device 100 has multiple first magnetic adsorption components 130. Each second magnetic adsorption component 210 is correspondingly arranged with at least one first magnetic adsorption component 130. This enables simultaneous adsorption at multiple positions, improving stability and positioning accuracy.

[0076] In some embodiments, the cutter head 200 includes a first side portion 220, a second side portion 240, and a protrusion 230. The first side portion 220 and the second side portion 240 are respectively connected to the two sides of the protrusion 230. The protrusion 230 protrudes downward relative to the first side portion 220 and the second side portion 240. A second magnetic adsorption assembly 210 is disposed on the protrusion 230. When the cutter head 200 is adsorbed and fixed to the cutter head fixing device 100, the first side portion 220 is disposed on the first step structure 121 of the support member 110, the second side portion 240 is disposed on the second step structure 122 of the support member 110, and the protrusion 230 is disposed on the main body portion 120 of the support member 110. This improves the stability of the support member 110 in supporting the cutter head 200 and enhances the accuracy of their relative positions.

[0077] Please see Figure 9 In some embodiments, the circuit board processing equipment 10 further includes a positioning assembly 400, which can be mounted on the worktable 300. The positioning assembly 400 includes a positioning cylinder 420 and a positioning element 410. The positioning cylinder 420 is disposed below the cutter head fixing device 100, and the positioning element 410 is connected to the output end of the positioning cylinder 420, so that the positioning cylinder 420 can drive the positioning element 410 to rise or fall through its output end. The positioning element 410 is provided with a positioning pin 411 for cooperating with the cutter head 200.

[0078] The support member 110 is also provided with a clearance groove 124. In the height direction Z, the clearance groove 124 corresponds to the position of the support member 110, and the clearance groove 124 is used to avoid the positioning member 410. When the positioning cylinder 420 drives the positioning member 410 to rise, the positioning member 410 moves upward, and the positioning pin 411 of the positioning member 410 can be inserted into the positioning hole 250 of the cutter head 200 fixed on the support member 110. The depth of the positioning pin 411 inserted into the cutter head 200 is greater than or equal to the maximum deformation of the elastic member 140. Thus, when the cutter head 200 is picked up without disconnecting the magnet, the compression of the elastic member 140 will not cause the cutter head 200 to disengage from the positioning pin 411.
