Description

Technical Field

[0001] This application relates to the field of CNC machine tools for printed circuit boards, and in particular to clamping devices and circuit board processing equipment. Background Technology

[0002] To ensure optimal processing of printed circuit boards (PCBs) by the processing equipment, they need to be positioned before processing. A common positioning method is to first drill pin holes on the PCB, and then drill corresponding pin holes on the processing table panel. After the pins are inserted into the pin holes on the processing table panel, the pin holes on the PCB panel are then fitted onto the pins for positioning, ensuring that the PCB and processing table panel fit together securely during processing and do not shift.

[0003] In existing technologies, machining equipment includes multiple spindle assemblies. Generally, each spindle assembly includes a base plate, a spindle, and a clamping device. Both the spindle and the clamping device are mounted on the base plate. The clamping device is used to hold pins or cutting tools. In the horizontal direction, the spindle and clamping device move synchronously by driving the base plate. In the vertical direction, the spindle and clamping device move independently. However, due to factors such as machining errors, assembly errors, and machining conditions, the distance between the clamping device and the spindle cannot be guaranteed to meet requirements, thus affecting the positioning accuracy of the pin insertion / removal.

[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In existing technologies, pin positioning is commonly used for PCB positioning. However, due to assembly errors and other factors, the distance between the clamping device and the spindle cannot be guaranteed to meet requirements, thus affecting the accuracy of the clamping device in inserting or removing the pins, resulting in low pin positioning accuracy. To address this problem, this application provides a clamping device.

[0038] See Figures 1-6 , Figure 1 This is a schematic diagram of a clamping device provided in an embodiment of this application. Figure 2 This is a schematic diagram showing the separation of the cylinder barrel and cylinder head in a clamping device provided in an embodiment of this application. Figure 3 This is a partial schematic diagram of a clamping assembly provided in an embodiment of this application. Figure 4 This is a cross-sectional view of a clamping device provided in an embodiment of this application. Figure 5 This is a schematic diagram of a clamping device provided in another embodiment of this application. Figure 6 This is a cross-sectional view of a clamping device provided in another embodiment of this application. A clamping device 10 provided in one embodiment of this application is applied to a circuit board processing equipment. The circuit board processing equipment includes a spindle 500. The clamping device 10 includes a clamping assembly 300 and an adjusting assembly. The clamping assembly 300 and the spindle 500 are spaced apart along a first direction. The adjusting assembly is connected to the clamping assembly 300 and can adjust the distance between the clamping assembly 300 and the spindle 500 in the first direction.

[0039] Specifically, this application connects the adjusting component to the clamping component 300 and can adjust the distance between the clamping component 300 and the spindle 500 in the first direction. This can solve the error in the distance between the clamping component 300 and the spindle 500 in the first direction caused by factors such as machining error, assembly error and machining conditions, so as to ensure that the distance between the clamping component 300 and the spindle 500 in the first direction meets the requirements and improve the accuracy of inserting and removing the pins of the clamping device 10.

[0040] See Figure 1 , Figure 2 , Figure 5 and Figure 6 In one embodiment, the clamping device 10 further includes a lifting assembly 200, and a clamping assembly 300 connected to the lifting assembly 200. The lifting assembly 200 can drive the clamping assembly 300 to move up and down along a second direction, where the first direction intersects the second direction. The lifting assembly 200 has a first mounting hole 221, and the adjusting assembly includes a fastener 410, which passes through the first mounting hole 221 and is connected to the clamping assembly 300. The first mounting hole 221 extends along a first direction, and the fastener 410 can move within the first mounting hole 221 along the first direction to adjust the distance between the clamping assembly 300 and the spindle 500 in the first direction.

[0041] Specifically, the first mounting hole 221 is an elongated hole extending along a first direction. When the fastener 410 passes through the first mounting hole 221, there is a gap between the fastener 410 and the hole wall of the first mounting hole 221 in the first direction. This allows the fastener 410 to drive the clamping assembly 300 to move relative to the hole wall of the first mounting hole 221 along the first direction, thereby adjusting the position of the clamping assembly 300 relative to the upgrading assembly in the first direction. This allows for adjusting the position of the clamping assembly 300 relative to the spindle 500 in the first direction, ensuring that the distance between the clamping assembly 300 and the spindle 500 in the first direction meets the requirements and improving the accuracy of the clamping device 10 in inserting and removing the pin. The lifting assembly 200 is connected to the base plate 600 and is drively connected to the clamping assembly 300. The lifting assembly 200 can drive the clamping assembly 300 to move up and down along a second direction, thereby moving closer to and away from the pin to achieve the insertion and removal of the pin. Preferably, the second direction is perpendicular to the first direction.

[0042] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the clamping assembly 300 has a second mounting hole 310, and a fastener 410 passes through the second mounting hole 310. The second mounting hole 310 extends along a third direction, and the fastener 410 is movable within the second mounting hole 310 along the third direction to adjust the spacing between the clamping assembly 300 and the spindle 500 in the third direction, wherein the third direction intersects with both the first and second directions.

[0043] Specifically, the second mounting hole 310 is an elongated hole extending along a third direction. When the fastener 410 passes through the second mounting hole 310, there is a gap between the fastener and the hole wall of the second mounting hole 310 in the third direction. This allows the fastener 410 to drive the clamping component 300 to move relative to the hole wall of the second mounting hole 310 in the third direction, thereby adjusting the position of the clamping component 300 relative to the lifting component 200 in the third direction. This allows for adjustment of the position of the clamping component 300 relative to the spindle 500 in the third direction, ensuring the spacing error between each clamping component 300 and the spindle 500 in the third direction and improving the pin-driving accuracy.

[0044] In this application, a first mounting hole 221 extending along a first direction is provided on the lifting assembly 200, and a second mounting hole 310 extending along a third direction is provided on the clamping assembly 300. This allows the clamping assembly 300 to move relative to the lifting assembly 200 along both the first and third directions. Fasteners 410 are then inserted through the first and second mounting holes 221 and 310 to fix the clamping assembly 300 to the lifting assembly 200, thus fixing the position between the clamping assembly 300 and the lifting assembly 200. This ensures that the distance between the clamping assembly 300 and the spindle 500 in the first direction meets the requirements. In other words, this application only requires adjusting the relative position of the clamping assembly 300 with respect to the lifting assembly 200 to achieve position adjustment of the clamping assembly 300 relative to the spindle 500 in both the first and third directions, simplifying the process and improving position adjustment efficiency. Preferably, the third direction is perpendicular to both the first and second directions.

[0045] It should be noted that the instruction manual is attached. Figure 1 Taking this example, we define XX' as the first direction, YY' as the third direction, and ZZ' as the second direction. The following descriptions will all use the first direction, the second direction, and the third direction.

[0046] See Figure 1 , Figure 2 and Figure 3In one embodiment, the outer wall of the clamping assembly 300 is provided with a clearance groove 320, which communicates with the second mounting hole 310. The fastener 410 includes a fastening rod 411 and a locking block 412. The fastening rod 411 passes through the first mounting hole 221 and the second mounting hole 310 and extends partially into the clearance groove 320. The locking block 412 is accommodated in the clearance groove 320 and connected to the fastening rod 411. The locking block 412 abuts against the clamping assembly 300 to limit the relative position between the clamping assembly 300 and the lifting assembly 200.

[0047] Specifically, the fastening rod 411 passes through the first mounting hole 221 and the second mounting hole 310, and the end of the fastening rod 411 away from the locking block 412 abuts against the lifting assembly 200, and abuts against the clamping assembly 300 through the locking block 412 connected to the fastening rod 411, thereby clamping the lifting assembly 200 and the clamping assembly 300 to limit the position between the clamping assembly 300 and the lifting assembly 200 in the first direction and the third direction, thereby improving the reliability of the clamping device 10. Preferably, the fastening rod 411 is a bolt, the locking block 412 is a nut, and the locking block 412 is sleeved on the fastening rod 411.

[0048] See Figure 5 and Figure 6 In another embodiment, the fastener 410 is threaded to the wall of the second mounting hole 310, and the fastener 410 is movable relative to the wall of the first mounting hole 221 in a first direction to adjust the position of the clamping assembly 300 relative to the lifting assembly 200 in the first direction.

[0049] See Figure 1 , Figure 2 and Figure 6 In one embodiment, the clamping device 10 further includes a support plate 430 connected to the lifting assembly 200, which can support the clamping assembly 300.

[0050] Specifically, when the fastener 410 is loosened to adjust the position of the clamping assembly 300 relative to the lifting assembly 200 in the first direction and the third direction, the clamping assembly 300 can be supported by the support plate 430, thereby preventing the clamping assembly 300 from separating from the lifting assembly 200. That is, it is not necessary to hold the clamping assembly 300 with your hand. You only need to control the clamping assembly 300 to move relative to the lifting assembly 200 in the first direction and the third direction. This improves the convenience of adjusting the position of the clamping assembly 300 relative to the lifting assembly 200, and thus improves the convenience of adjusting the position of the clamping assembly 300 relative to the spindle 500.

[0051] Furthermore, the clamping assembly 300 has an abutment surface 330 on the side opposite to the lifting assembly 200. The plane containing the abutment surface 330 is perpendicular to the second direction. The support plate 430 can fit against the abutment surface 330, thereby applying a stable force towards the second direction to the clamping assembly 300. The second direction is parallel to the direction of gravity. Therefore, after the clamping assembly 300 is positioned relative to the lifting assembly 200 in the first and third directions, the support plate 430 ensures that the position of the clamping assembly 300 relative to the lifting assembly 200 in the first and third directions remains unchanged. This allows the fastener 410 to stably fix the clamping assembly 300 and the lifting assembly 200, improving positional accuracy.

[0052] See Figure 1 , Figure 2 and Figure 6 In one embodiment, there is a gap between the tray 430 and the clamping assembly 300 in the second direction, so that when the clamping assembly 300 moves relative to the lifting assembly 200 in the first and third directions, the friction between the clamping assembly 300 and the tray 430 and the lifting assembly 200 can be reduced, thereby improving the smoothness of the position adjustment of the clamping assembly 300 relative to the lifting assembly 200 and improving the position adjustment efficiency.

[0053] Furthermore, the lifting assembly 200 has an extension 226 extending in the second direction, and the support plate 430 is connected to the end of the extension 226. The clamping assembly 300 has a protrusion 340, and the abutment surface 330 is located on the side of the protrusion 340 facing the support plate 430 for engaging with the support plate 430. By providing the protrusion 340, interference with the clamping end of the clamping assembly 300 can be reduced, and the reliability of the clamping device 10 can be improved.

[0054] See Figure 1 and Figure 2 In one embodiment, the clamping device 10 further includes a guide assembly 420 and a fixed base 100. The guide assembly 420 includes a slider 421 and a guide rail 422. The guide rail 422 is disposed on the fixed base 100, and the slider 421 is disposed on the lifting assembly 200. The slider 421 and the guide rail 422 are slidably connected along a second direction.

[0055] Specifically, the guide rail 422 extends along the second direction and slides in cooperation with the slider 421. The guide rail 422 can slide relative to the slider 421 along the second direction, thereby guiding the lifting assembly 200 to move the clamping assembly 300 along the second direction. It can also limit the position of the lifting assembly 200 relative to the fixed seat 100 in the first and third directions, thereby reducing the shaking of the lifting assembly 200 and the clamping assembly 300 when the clamping assembly 300 inserts or removes the pin, and improving the insertion and removal accuracy.

[0056] See Figure 1 , Figure 4 and Figure 7 , Figure 7 This is a schematic diagram of the connecting plate in a clamping device provided in one embodiment of this application. In one embodiment, the lifting assembly 200 includes a cylinder body 220 and an output shaft 210 that are slidably connected. The fixed base 100 is provided with a third mounting hole 110 that extends along a first direction. One end of the output shaft 210 passes through the third mounting hole 110 to connect with the fixed base 100. The cylinder body 220 is connected to the clamping assembly 300. The lifting assembly 200 can move within the third mounting hole 110 along the first direction, thereby enabling the lifting assembly 200 to drive the clamping assembly 300 to move in the first direction. This further adjusts the position of the clamping assembly 300 and the main shaft 500 in the first direction, increases the range of distance adjustment between the clamping assembly 300 and the main shaft 500 in the first direction, and improves the adaptability of the clamping device 10.

[0057] Furthermore, the fixing base 100 includes a fixing plate 120 and a connecting plate 130 connected to each other. The fixing plate 120 and the connecting plate 130 are arranged vertically. The guide rail 422 is disposed on the fixing plate 120, and the third mounting hole 110 is disposed on the connecting plate 130.

[0058] See Figure 4 and Figure 6 In one embodiment, the cylinder body 220 includes a cylinder head 223 and a cylinder barrel 222. A first mounting hole 221 is provided on the cylinder head 223 and the cylinder barrel 222. The clamping device 10 also includes a fixing member 224, which passes through the cylinder head 223 and the cylinder barrel 222 to fix the cylinder head 223 to the cylinder barrel 222. This prevents the cylinder head 223 from warping under the pressure of the air inside the cylinder barrel 222 when the locking block 412 is removed from the fastening rod 411, thus improving the reliability of the clamping device 10. Preferably, the fixing member 224 is a screw.

[0059] See Figure 4 and Figure 6 In one embodiment, one of the cylinder barrel 222 and the cylinder head 223 is provided with a positioning member 225, and the other of the cylinder barrel 222 and the cylinder head 223 is provided with a positioning hole 227 corresponding to the positioning member 225. The positioning member 225 is inserted into the positioning hole 227 for coarse positioning, and also to prevent the cylinder head 223 from rotating relative to the cylinder barrel 222 when the fastener 224 is tightened, thereby improving assembly efficiency. In this embodiment, the positioning member 225 is provided on the cylinder barrel 222. Preferably, the positioning member 225 is a pin.

[0060] In other embodiments, the lifting assembly 200 may also be one of a hydraulic mechanism, a motor screw assembly, a linear motor, an electric push rod, a gear and rack assembly, or a worm gear assembly.

[0061] See Figures 1-8 , Figure 8 This is a front view of a circuit board processing apparatus provided in an embodiment of this application. This application also provides a circuit board processing apparatus, including the aforementioned clamping device 10, and further including a base plate 600 and a spindle 500. Both the clamping device 10 and the spindle 500 are connected to the base plate 600, and the clamping device 10 and the spindle 500 are spaced apart along a first direction.

[0062] This application connects to the clamping assembly by means of an adjusting component, and can adjust the distance between the clamping assembly and the spindle 500 in the first direction. This can solve the error in the distance between the clamping assembly and the spindle 500 in the first direction caused by factors such as machining error, assembly error and machining conditions, so as to ensure that the distance between the clamping assembly and the spindle 500 in the first direction meets the requirements and improve the accuracy of inserting and removing the pins of the clamping device 10.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
