Description

Technical Field

[0001] This application relates to the field of circuit board processing technology, and in particular to positioning devices and circuit board processing equipment used in circuit board processing equipment. Background Technology

[0002] When processing circuit boards, the general procedure is to first make positioning holes on the circuit board, and then drill corresponding positioning holes on the worktable. After the positioning components are inserted into the positioning holes on the worktable, the positioning holes on the circuit board are then fitted onto the positioning components to ensure that the circuit board does not shift during processing.

[0003] As usage frequency increases, the positioning holes on the worktable will deform, thus affecting positioning accuracy. Utility Model Content

[0004] Therefore, it is necessary to provide a positioning device for circuit board processing equipment to address the problem that the positioning holes on the existing worktable affect the positioning accuracy.

[0005] A positioning device for use in circuit board processing equipment, the circuit board processing equipment including a worktable, the worktable having a plurality of countersunk holes arranged at intervals, the positioning device comprising:

[0006] A workbench, wherein multiple countersunk holes are arranged at intervals on the workbench;

[0007] A connector is detachably connected to the countersunk hole; the connector is provided with a positioning hole.

[0008] A positioning element is connected to the positioning hole, and the positioning element is used to fix the circuit board to be processed.

[0009] In one embodiment, the surface of the connector is not higher than the surface of the worktable;

[0010] And / or, the positioning element and the positioning hole are interference fit connections.

[0011] In one embodiment, the countersunk hole is a threaded hole, and the connector is threaded into the threaded hole.

[0012] In one embodiment, the connector is provided with a first magnetic attractor, and the wall of the countersunk hole is provided with a second magnetic attractor, the second magnetic attractor being magnetically connected to the first magnetic attractor.

[0013] In one embodiment, in a first state, the first magnetic attractor and the second magnetic attractor have magnetic force; in a second state, the first magnetic attractor and the second magnetic attractor do not have magnetic force.

[0014] One of the first state and the second state is the energized state, and the other is the de-energized state.

[0015] In one embodiment, the connector is configured with an operating part for connecting a disassembly tool.

[0016] In one embodiment, the operating part is configured as an operating groove, which is disposed on one side of the connector along its own radial direction.

[0017] In one embodiment, the positioning device applied to the circuit board processing equipment further includes a robotic arm connected to an assembly / disassembly tool for connection to the operating unit.

[0018] In one embodiment, the assembly / disassembly tool is configured with a mating part for engaging with the operating part;

[0019] And / or, the operating part is provided with a third magnetic suction member, and the assembly / disassembly tool is provided with a fourth magnetic suction member that can be magnetically connected to the third magnetic suction member.

[0020] A circuit board processing equipment includes a frame and a positioning device as described above for use in circuit board processing equipment, wherein the worktable is connected to the frame.

[0021] In one embodiment, the circuit board processing equipment includes a circuit board drilling device, which includes a positioning element insertion and removal mechanism for inserting or removing the positioning element from the positioning hole of the connector.

[0022] The aforementioned positioning device for circuit board processing equipment, by setting countersunk holes on the worktable, allows for the detachable connection of connectors to these holes. Positioning holes are also provided on the connectors, connecting to positioning elements for the circuit boards. This enables precise positioning of the circuit boards on the worktable, ensuring they do not shift during processing. By connecting the connectors to countersunk holes at different locations, circuit boards of different sizes and shapes can be positioned without needing to readjust the worktable, meeting user requirements and improving production efficiency. With increased usage, if the positioning holes deform due to repeated insertions and removals (e.g., the diameter increases), the connectors can be removed and replaced, maintaining positioning accuracy. Furthermore, the entire worktable does not need to be processed or replaced, reducing replacement costs and complexity. Since there is no need to drill positioning holes directly on the worktable, the possibility of damage to the worktable surface is reduced, extending the worktable's lifespan.

[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[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.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] See Figures 1 to 2 as well as Figure 5As shown, an embodiment of this application provides a positioning device applied to a circuit board processing equipment. The circuit board processing equipment includes a worktable 100, on which a plurality of countersunk holes 110 are arranged at intervals. It is understood that the circuit board processing equipment can be a drilling machine, a forming machine, a router, or a drilling and router integrated machine, etc., and is not limited thereto. In some embodiments, the circuit board processing equipment can be a drilling machine, which performs drilling processing on the circuit board. During drilling, the positioning device positions the circuit board to ensure that it does not shift during processing, thus guaranteeing the processing effect. The positioning device includes a connector 200 and a positioning member 300. The connector 200 is detachably connected to the countersunk hole 110; the connector 200 has a positioning hole 210; the positioning member 300 is connected to the positioning hole 210 and is used to fix the circuit board to be processed (not shown). In a practical application scenario, the circuit board can be a printed circuit board (PCB).

[0038] By providing countersunk holes 110 on the worktable 100, the connector 200 can be detachably connected to the countersunk holes 110. By providing positioning holes 210 on the connector 200, a positioning component 300 for positioning the circuit board can be connected, thus enabling the circuit board to be positioned on the worktable 100 and ensuring that the circuit board does not shift during processing. By connecting the connector 200 to countersunk holes 110 at different positions, circuit boards of different sizes and shapes can be positioned without readjusting the worktable 100, meeting user needs while improving production efficiency. With increased usage frequency, if the positioning holes 210 deform due to repeated insertions and removals (e.g., the diameter increases), the connector 200 can be removed and replaced with a new one, ensuring positioning accuracy. Simultaneously, there is no need to process or replace the entire worktable 100, reducing replacement costs and difficulty. Since there is no need to directly drill positioning holes 210 on the worktable 100, the possibility of damage to the surface of the worktable 100 is reduced, extending the service life of the worktable 100.

[0039] See Figures 1 to 2 as well as Figure 5As shown, it can be understood that at least two countersunk holes 110 are arranged along the length direction of the worktable 100, and at least two countersunk holes 110 are arranged along the width direction of the worktable 100. This not only increases the contact area between the positioning member 300 and the circuit board, improving the positioning accuracy and reliability of the circuit board, but also allows the positioning member 300 to be connected at different positions according to user needs, thereby positioning circuit boards of different sizes. During processing, the spindle of the circuit board processing equipment can be used to directly drill holes in the connector 200. After multiple insertions and removals of the positioning hole 210 of the connector 200 at the same location, the old connector 200 can be replaced, a new connector 200 installed, and the positioning hole 210 can be re-drilled using the spindle. In other embodiments, the positioning hole 210 can also be pre-drilled on the connector 200 before connecting the connector 200 to the countersunk hole 110.

[0040] In some embodiments, the workbench 100 includes a bakelite board with countersunk holes 110 disposed thereon. The bakelite board, as part of the workbench 100, supports the circuit board to be processed, ensuring stability and accuracy during the drilling process. In some embodiments, the bakelite board is made of phenolic resin, which has excellent mechanical strength, wear resistance, and electrical insulation properties, effectively preventing current leakage, protecting operator safety, and ensuring that electronic components are not affected. In some embodiments, the bakelite board may also be made of epoxy resin or glass fiber reinforced plastic.

[0041] See Figure 5 As shown, in one embodiment, the surface of the connector 200 is not higher than the surface of the worktable 100. For example, in the embodiment shown in the figures, the surface of the connector 200 is lower than the surface of the worktable 100. This prevents obstruction when moving circuit boards or other components, reducing the risk of damage due to collisions and ensuring smoother operation on the worktable 100 (such as placing, moving, and removing circuit boards), thus improving operational efficiency. Furthermore, the flat surface of the worktable 100 reduces the risk of operators tripping or being scratched by protruding parts, especially in cases of frequent circuit board replacement or precision operations. It avoids potential damage to other equipment or tools due to the protruding connector 200, extending the overall lifespan of the equipment. Simultaneously, the flush design helps ensure more accurate alignment of the circuit board with the positioning hole 210 during placement, reducing minor offsets caused by height differences and improving positioning accuracy. In other embodiments, the surface of the connector 200 is at the same height as the surface of the worktable 100, i.e., flush, ensuring uniform and stable support for the circuit board throughout the processing, preventing deformation or displacement due to insufficient local support.

[0042] In some embodiments, the positioning element 300 and the positioning hole 210 are connected by an interference fit, meaning that the diameter of the positioning element 300 is slightly larger than the diameter of the positioning hole 210, allowing for a very tight connection when the positioning element 300 is inserted into the positioning hole 210. This tight fit provides a strong mechanical locking effect, ensuring that the relative positions of the positioning element 300 and the positioning hole 210 remain fixed, reducing the possibility of displacement or wobbling of the positioning element 300, thereby improving positioning accuracy. In some embodiments, the positioning element 300 can be a pin, and the positioning hole 210 can be a pin hole.

[0043] See Figure 5 As shown, in one embodiment, the countersunk hole 110 is constructed as a threaded hole, and the connector 200 is threaded into the threaded hole. The threaded connection provides strong fastening force, ensuring a stable connection between the connector 200 and the worktable 100, preventing loosening or displacement due to vibration or external forces during processing. The threaded connection allows for fine-tuning by rotating the connector 200, ensuring accurate installation in the predetermined position, thereby improving overall positioning accuracy. Each installation, as long as it is tightened to the specified torque, ensures the same installation accuracy. Furthermore, by adjusting the depth or preload of the threaded connection, the position and tightness of the connector 200 can be flexibly adjusted according to actual needs, adapting to different application scenarios. The connector can be a screw or a component with external threads.

[0044] In some embodiments, a spring washer (not shown) or a lock nut (not shown) may be added to the threaded connection to increase the anti-loosening effect and further improve the positioning effect of the device on the circuit board.

[0045] See Figure 2 As shown, in one embodiment, the connector 200 is provided with a first magnetic chuck 230, and the wall of the countersunk hole 110 is provided with a second magnetic chuck (not shown). The second magnetic chuck can be magnetically connected to the first magnetic chuck 230. The magnetic attraction between the first magnetic chuck 230 and the second magnetic chuck helps guide the connector 200 accurately into the countersunk hole 110, reducing the need for manual adjustment. This allows the connector 200 to be quickly aligned and fixed into the countersunk hole 110 on the worktable 100, greatly simplifying the assembly process and ensuring high-precision positioning for each installation. Similarly, the stable connection provided by the first magnetic chuck 230 and the second magnetic chuck prevents the connector 200 from shifting or loosening during processing, maintaining the precise positioning of the circuit board. Simultaneously, the natural attraction between the first magnetic chuck 230 and the second magnetic chuck reduces the chance of hard collisions, thereby reducing wear between components and extending the service life of the connector 200 and the worktable 100.

[0046] In one embodiment, in a first state, the first magnetic chuck 230 and the second magnetic chuck have magnetic force; in a second state, the first magnetic chuck 230 and the second magnetic chuck do not have magnetic force; one of the first state and the second state is an energized state, and the other is an de-energized state. For example, the first state is an energized state, and the second state is a de-energized state. In the energized state, a magnetic force is generated between the first magnetic chuck 230 and the second magnetic chuck, which can quickly attract and firmly fix the connector 200 to the countersunk hole 110 on the worktable 100, realizing a fast and automated installation process; the magnetic attraction between the first magnetic chuck 230 and the second magnetic chuck further ensures a stable connection between the connector 200 and the worktable 100, reducing the risk of accidental loosening due to vibration or other external forces. In the de-energized state, the magnetic force between the first magnetic chuck 230 and the second magnetic chuck disappears, allowing the connector 200 to be easily removed or repositioned, simplifying disassembly and adjustment operations and improving work efficiency. Moreover, the power is cut off when the magnetic fixation is not needed, saving energy consumption.

[0047] By controlling the on / off state of the current, the states of the first magnetic chuck 230 and the second magnetic chuck can be flexibly switched according to actual needs, improving the efficiency of installation or disassembly. Understandably, in other embodiments, the first state can also be a power-off state, and the second state can be a power-on state. That is, in the power-off state, a magnetic force is generated between the first magnetic chuck 230 and the second magnetic chuck; in the power-on state, the magnetic force between the first magnetic chuck 230 and the second magnetic chuck disappears. Understandably, the first magnetic chuck 230 and the second magnetic chuck can be made of common magnetic materials, such as neodymium iron boron, neodymium iron boron, and AlNiCo.

[0048] See Figure 2 As shown, in one embodiment, the connector 200 is equipped with an operating section 220 for connecting assembly / disassembly tools. The design of the operating section 220 allows the connector 200 to be quickly and accurately installed onto or removed from the workbench 100 using specialized tools, without complicated steps or additional auxiliary tools, greatly improving assembly and disassembly speed and reducing downtime. With the aid of the tools, operators can more precisely control the position and angle of the connector 200, ensuring accurate installation and improving overall positioning accuracy. Simultaneously, the design of the operating section 220 helps guide the correct application of force by the tools, preventing slippage of the connector 200 or other safety hazards caused by improper operation, thus protecting operator safety. Furthermore, the operating section 220 can be designed in different shapes and sizes to accommodate various types of tools (such as wrenches, screwdrivers, etc.), increasing the system's versatility and flexibility.

[0049] See Figure 2As shown, in one embodiment, the operating part 220 is configured as an operating groove 221, which is disposed on one side of the connector 200 along its own radial direction. Since the operating groove 221 is located on the side of the connector 200, the tool can be easily approached from the side and inserted into the groove for operation without complex positioning or adjustment; moreover, because the operating groove 221 is located on the side, it will not interfere with the movement of other components or the worktable 100. By providing the operating groove 221, the tool can be more securely fixed to the connector 200, ensuring that it will not slip or deviate during rotation or force application, thereby achieving more precise operation, making the contact between the tool and the connector 200 tighter, reducing the risk of tool slippage, and protecting the safety of the operator.

[0050] In other embodiments, the operating part 220 can also be an operating plane. That is, by cutting off the two opposite sides of the cylindrical connector 200, the cross-section of the connector 200 is made to be waist-shaped. The installation and disassembly tool is clamped on the operating plane, so that the installation or disassembly operation of the connector 200 can be realized.

[0051] In some embodiments, the operating part 220 is provided with an anti-slip texture (not shown) or is coated with a special material to increase friction, making the connection between the assembly / disassembly tool and the operating part 220 tighter and preventing slippage.

[0052] In one embodiment, the positioning device applied to the circuit board processing equipment also includes a robotic arm (not shown), which is connected to an assembly / disassembly tool for connection to the operating unit 220. The robotic arm can automatically perform the tasks of installing and disassembling the connector 200, reducing manual intervention and significantly improving work efficiency. Furthermore, this automated operation reduces reliance on skilled operators, lowers labor costs, and simultaneously increases production efficiency.

[0053] In one embodiment, the assembly / disassembly tool is equipped with a mating part (not shown) for engaging with the operating part 220. Through this engagement, the assembly / disassembly tool is securely fixed to the connector 200 during operation, preventing slippage or detachment and ensuring operational stability. This stable connection allows the assembly / disassembly tool to transmit applied torque more effectively, making tightening and loosening the connector more efficient. Furthermore, the design of the mating part allows the assembly / disassembly tool to quickly locate and insert into the operating part 220 without complex calibration steps, greatly simplifying the operation process. In some embodiments, the operating part 220 can be an operating groove 221, and correspondingly, the mating part can be a snap-fit ​​block, the shape of which is adapted to the shape of the operating groove 221.

[0054] In some embodiments, the operating part 220 is provided with a third magnetic chuck (not shown), and the assembly / disassembly tool is provided with a fourth magnetic chuck (not shown) capable of magnetically engaging with the third magnetic chuck. Through the attraction between the third and fourth magnetic chucks, the assembly / disassembly tool can quickly locate and accurately align with the operating part 220 (such as the operating groove 221) on the connector 200, achieving a fast and secure snap-fit, avoiding the complexity and time consumption of manual calibration. The additional holding force provided by the magnet helps prevent the assembly / disassembly tool from accidentally sliding or disengaging during operation, ensuring the stability of the operation process.

[0055] In some embodiments, the third and fourth magnetic components can also refer to the aforementioned configuration of the first and second magnetic components. For example, in the energized state, the third and fourth magnetic components have magnetic force; in the de-energized state, they do not have magnetic force. Alternatively, in the de-energized state, the third and fourth magnetic components have magnetic force; in the energized state, they do not have magnetic force. By controlling the on / off state of the current, the states of the third and fourth magnetic components can be flexibly switched according to actual needs, improving the efficiency of installation or removal.

[0056] Furthermore, one embodiment of this application also provides a circuit board processing device, including a frame and the positioning device described above, with a worktable 100 connected to the frame. During use, as the insertion and removal frequency increases, when the positioning hole 210 deforms (e.g., the hole diameter increases), the connector 200 can be removed and replaced with a new connector 200, ensuring positioning accuracy. Simultaneously, it eliminates the need to process and replace the entire worktable 100, reducing replacement costs and difficulty. Since there is no need to directly drill positioning holes 210 on the worktable 100, the possibility of damage to the surface of the worktable 100 is reduced, extending the service life of the worktable 100.

[0057] Understandably, circuit board processing equipment can be drilling equipment, forming equipment, milling machine equipment, or integrated drilling and milling equipment, etc., without any restrictions.

[0058] In some embodiments, the circuit board processing equipment includes a circuit board drilling device for drilling holes in the circuit board. During drilling, the positioning device positions the circuit board to ensure it does not shift during processing, thus guaranteeing the processing effect. In some embodiments, the circuit board drilling device includes a positioning element insertion / removal mechanism for inserting or removing a positioning element from a positioning hole in a connector.

[0059] The positioning component insertion and removal mechanism automates the insertion and removal process, reducing manual intervention, improving work efficiency, and ensuring smooth and safe insertion and removal of the positioning component. This avoids the risks associated with manual operation, such as pinching or other injuries, and also reduces wear on the positioning component and positioning hole, extending their service life and lowering maintenance costs. In some embodiments, the positioning component insertion and removal mechanism may include a lifting drive unit and a clamping unit. The lifting drive unit drives the clamping unit to rise or fall, and the clamping unit grasps or releases the positioning component, thereby completing the insertion and removal operation. In some embodiments, the lifting drive unit may be a cylinder or a linear motor, and the clamping unit may be a mechanical gripper.

[0060] 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.

[0061] 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.
