However, manual positioning of pins and circuit boards is prone to positioning errors, which can lead to problems such as positional shifts, floating, and positioning difficulties after soldering, thereby reducing the production quality of lamp boards. Utility Model Content

[0006] According to one aspect of this application, an auxiliary fixture for welding a lamp board is provided. The lamp board includes a circuit board and pins. The auxiliary fixture is used for relative positioning and assembly of the circuit board and the pins. The auxiliary fixture includes a base plate, a mounting component, and a cover plate. A positioning groove is recessed on the upper surface of the base plate. The positioning groove is used to position the circuit board, and the peripheral sidewall of the positioning groove is used to abut against the outer peripheral wall of the circuit board to limit the horizontal movement of the circuit board. A mounting groove is recessed on the base plate. In a horizontal projection plane, at least a portion of the mounting groove is located within the enclosure of the positioning groove. The mounting groove is located below the positioning groove. The mounting component is detachably mounted in the mounting groove, and the peripheral sidewall of the mounting component abuts against... The mounting component is held against the inner peripheral wall of the mounting groove to limit its horizontal movement. A positioning hole is provided on the mounting component, located within the positioning groove, for accommodating and positioning the pin. A cover plate is movably mounted on the upper surface of the base plate. A welding joint is provided on the cover plate. When the positioning hole positions the pin and the positioning groove positions the circuit board, the pin passes through a pinhole on the circuit board. When the cover plate is closed on the base plate, the pinhole is exposed at the welding joint, and the bottom wall of the positioning groove abuts against the lower surface of the circuit board, while the lower surface of the cover plate abuts against the upper surface of the circuit board, thus limiting the circuit board's vertical movement.

[0007] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, during the soldering process of the lamp board, the pins are first placed into the positioning holes, and then the mounting parts are installed into the mounting grooves of the base plate, so that the mounting parts and the base plate cooperate to position the pins. Next, the circuit board is placed into the positioning groove, so that the peripheral sidewall of the positioning groove abuts against and limits the peripheral sidewall of the circuit board, and the lower surface of the circuit board abuts against the bottom wall of the positioning groove, so that the upper end of the pin passes through the pin hole of the circuit board, thereby achieving rapid and accurate positioning of the pins and the circuit board. Finally, the cover plate is closed on the base plate to press the circuit board into the positioning groove, thereby facilitating the rapid soldering of the subsequent lamp board and improving the soldering efficiency of the lamp board.

[0008] In this embodiment, the base plate is provided with a plurality of positioning grooves, which are spaced apart along a first direction; the mounting groove extends along the first direction to pass through the plurality of positioning grooves; the mounting member extends relative to the mounting groove along the first direction, and the mounting member is provided with a plurality of positioning holes corresponding to the plurality of positioning grooves.

[0013] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: Multiple positioning posts form a positioning groove, which reduces the contact area between the positioning posts and the circuit board while limiting the horizontal movement of the circuit board by the positioning posts. This reduces the friction between the positioning posts and the circuit board, making it easier for the circuit board to come out of the positioning groove.

[0014] In this embodiment, a first clearance groove is recessed on the bottom wall of the positioning groove to avoid electronic components on the lower side of the circuit board; and / or, a second clearance groove is recessed on the lower surface of the cover plate to avoid electronic components on the upper side of the circuit board.

[0015] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: The first clearance groove and / or the second clearance groove can avoid electronic components on the circuit board to protect the circuit board's safety, prevent the circuit board from being damaged under external pressure, and improve the reliability of the auxiliary tooling.

[0016] In this embodiment, a third clearance groove is provided on the base plate. In the horizontal plane, the third clearance groove is disposed on the periphery of the mounting groove to reduce the contact area between the mounting component and the inner peripheral wall of the mounting groove.

[0017] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: The third clearance groove can effectively reduce the contact area between the mounting part and the inner peripheral wall of the mounting groove, thereby reducing the friction between the mounting part and the mounting groove, making it easier for the mounting part to come out of the mounting groove, and improving the efficiency of the lamp board to detach from the auxiliary tooling.

[0018] In this embodiment, the base plate is provided with a lifting hole, which is located on the bottom wall of the mounting groove; the auxiliary tooling also includes a base, which is located below the base plate; a lifting column is provided on the base relative to the lifting hole; when the base plate is attached to the base, the lifting column can pass through the lifting hole and extend into the mounting groove to lift the mounting component.

[0019] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: After the lamp panel is welded, the base plate moves toward the base and fits against the base so that the lifting column can extend into the mounting slot through the lifting hole and lift the mounting component. This facilitates the quick removal of the mounting component from the mounting slot, improves the separation efficiency of the lamp panel, and makes it easier to transfer the lamp panel to subsequent processing steps.

[0020] In this embodiment, a guide notch is provided on the periphery of the lower surface of the base plate; a guide block is provided on the base relative to the guide notch; when the base plate is attached to the base, the guide block can extend into the guide notch so that the lifting column is aligned with the lifting hole.

[0022] In this embodiment, a first magnetic attractor is embedded on the upper surface of the base plate, and a second magnetic attractor is embedded on the lower surface of the cover plate relative to the first magnetic attractor. The first magnetic attractor and the second magnetic attractor can generate a magnetic attraction force to limit the cover plate to the base plate.

[0023] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: When the cover plate is closed on the base plate, the first and second magnetic components can generate magnetic attraction to keep the cover plate on the base plate, preventing the cover plate from moving away from the base plate during movement, preventing the circuit board from falling out of the positioning slot, and improving the reliability and stability of the auxiliary tooling.

[0024] In this embodiment, the upper surface of the base plate is provided with a positioning protrusion; the lower surface of the cover plate is provided with a positioning groove relative to the positioning protrusion; when the cover plate is placed on the base plate, the positioning protrusion can extend into the positioning groove to limit the movement of the cover plate relative to the base plate in the horizontal direction.

[0041] In related technologies, a light panel is installed on the vehicle body to provide illumination for the vehicle at night or in low light conditions, or to convey the vehicle's driving status and intentions to other road users through lights of different colors and flashing patterns.

[0042] Figure 1 This is a schematic diagram of the structure of the lamp panel of this utility model. Figure 2 yes Figure 1 The diagram shows a structural schematic from another perspective.

[0043] See Figure 1 and Figure 2 The lamp board includes a circuit board and pins. The circuit board is used to electrically connect electronic components such as light-emitting units. Pins pass through holes in the circuit board and are soldered to it to achieve electrical connection between the pins and the circuit board. The pins can also be electrically connected to external electrical devices to enable signal and power transmission between the circuit board and these devices.

[0044] In related technologies, the positioning and soldering of circuit boards and pins are generally achieved manually. This makes it easy for positioning errors to occur during the soldering process of the lamp board, which can lead to problems such as positional displacement, floating, and positioning difficulties between the circuit board and the pins. As a result, the production quality of the lamp board is poor and the production efficiency is low.

Figure 5 yes Figure 4 Enlarged view of the structure at point A in the middle. Figure 6 This is a structural schematic diagram of the mounting component of this utility model.

[0048] See Figures 1 to 6 This application provides an auxiliary tooling 30 (hereinafter referred to as auxiliary tooling 30) for welding a lamp board 10. The auxiliary tooling 30 may include a base plate 400. A positioning groove 420 is recessed on the upper surface of the base plate 400. The positioning groove 420 is used to position the circuit board 210. The peripheral sidewall of the positioning groove 420 is used to abut against the outer peripheral wall of the circuit board 210 to limit the horizontal movement of the circuit board 210. A mounting groove 440 for other components of the container is recessed on the base plate 400. In the horizontal projection plane, at least a portion of the mounting groove 440 is located within the enclosure of the positioning groove 420. The mounting groove 440 is located below the positioning groove 420.

[0049] The auxiliary tooling 30 may include a mounting member 500. The mounting member is used to receive and position the pin 220. The mounting member 500 is detachably mounted in the mounting groove 440. The peripheral sidewall of the mounting member 500 abuts against the inner peripheral wall of the mounting groove 440 to limit the horizontal movement of the mounting member 500. The mounting member 500 has a positioning hole 510 located in the positioning groove 420 for receiving and positioning the pin 220. When the positioning hole 510 positions the pin 220 and the positioning groove 420 positions the circuit board 210, the pin 220 passes through the pinhole on the circuit board 210.

[0050] The auxiliary fixture 30 may include a cover plate 600. The cover plate 600 is movably disposed on the upper surface of the base plate 400. A welding port 610 is provided on the cover plate 600. When the cover plate 600 is closed on the base plate 400, the pinhole is exposed at the welding port 610. Furthermore, the bottom wall of the positioning groove 420 is used to abut against the lower surface of the circuit board 210, and the lower surface of the cover plate 600 is used to abut against the upper surface of the circuit board 210, thereby limiting the movement of the circuit board 210 in the height direction.

[0051] When the lamp board 10 needs to be soldered, the pin 220 is positioned on the mounting part 500, and the mounting part 500 is moved into the mounting groove 440 so that the inner peripheral wall of the mounting groove 440 limits the horizontal movement of the mounting part 500, thereby positioning the pin 220.

[0052] Next, the circuit board 210 is placed in the positioning groove 420 so that the inner peripheral wall of the positioning groove 420 abuts against the peripheral side wall of the circuit board 210, thereby positioning the circuit board 210 so that the pin 220 passes through the pinhole on the circuit board 210.

[0053] Finally, the cover plate 600 is placed on the base plate 400 so that the bottom wall of the positioning groove 420 abuts against the lower surface of the circuit board 210 and the cover plate 600 presses against the upper surface of the circuit board 210, thereby pressing the circuit board 210 into the positioning groove 420, preventing the circuit board 210 from coming out of the positioning groove 420, and ensuring the positioning accuracy of the pin 220 and the circuit board 210 during the soldering process.

[0054] The auxiliary tooling 30 can effectively realize the relative positioning assembly of the pin 220 and the circuit board 210, thereby improving the positioning accuracy and efficiency of the pin 220 and the circuit board 210, avoiding problems such as offset and floating of the circuit board 210 and the pin 220 during the welding process, thus effectively improving the production quality and production efficiency of the lamp board 10.

[0055] Figure 7 This is a cross-sectional view of the mounting component of this utility model. Figure 8 This is a structural diagram of the pin and mounting component of this utility model when they are confined to the base plate. Figure 9 yes Figure 8 Enlarged view of the structure at point B.

[0056] See Figures 3 to 6 , Figures 7 to 9 In this embodiment, a plurality of positioning slots 420 are provided on the base plate 400. In the horizontal plane, the plurality of positioning slots 420 are spaced apart along the first direction so that the base plate 400 can simultaneously position a plurality of circuit boards 210, thereby improving the production efficiency of the lamp board 10.

[0057] In the horizontal plane, the second direction is perpendicular to the first direction.

[0058] See Figures 3 to 6 , Figure 8 , Figure 9 In this embodiment, multiple positioning slots 420 spaced apart along a first direction form positioning groups. Multiple positioning groups are provided on the base plate 400. These positioning groups are spaced apart along a second direction. The multiple positioning groups increase the number of positioning circuit boards 210 on the base plate 400, facilitating rapid processing of multiple lamp boards 10 and effectively improving the production efficiency of the lamp boards 10.

[0059] In some embodiments, a plurality of positioning grooves 420 are provided on the base plate 400, and the plurality of positioning grooves 420 are arranged in an array so that more positioning grooves 420 can be provided on the base plate 400, thereby improving the space utilization rate of the upper surface of the base plate 400 and thus improving the production efficiency of the lamp board 10.

[0060] See Figures 3 to 6 , Figure 8 , Figure 9In this embodiment, a working groove 410 is recessed in the base plate 400. A plurality of positioning posts 411 are spaced apart and protrude from the bottom wall of the working groove 410, forming a positioning groove 420. The positioning posts 411 can respectively abut against the peripheral sidewall of the circuit board 210 to limit the horizontal movement of the circuit board 210, thereby preventing the circuit board 210 from shifting. The bottom wall of the working groove 410 can abut against the lower surface of the circuit board 210 to limit the downward movement of the circuit board 210, thereby preventing the circuit board 210 from tilting in the height direction.

[0061] Furthermore, the spaced positioning posts 411 can reduce the contact area between the circuit board 210 and the positioning posts 411 while ensuring the limiting strength, thus reducing the friction between the circuit board 210 and the inner peripheral wall of the positioning groove 420. After the lamp board 10 is welded, the friction between the circuit board 210 and the inner peripheral wall of the positioning groove 420 is less, making it easier for the lamp board 10 to be removed from the positioning groove 420.

[0062] In some embodiments, the top of the positioning post 411 is flush with the upper surface of the base plate 400 in the vertical direction. When the cover plate 600 is pressed onto the base plate 400, the cover plate 600 can fit against the upper surface of the base plate 400. On the one hand, this prevents external debris from entering the working groove 410 through the gap between the cover plate 600 and the base plate 400, improving the reliability of the auxiliary tooling 30. On the other hand, it can stably press the circuit board 210 into the positioning groove 420, preventing the circuit board 210 from jumping in the height direction, thereby improving the welding quality in the subsequent welding process.

[0063] In some embodiments, a plurality of positioning posts 411 can be adapted to the inner peripheral wall of the working groove 410 to form a positioning groove 420, thereby simplifying the structure of the base plate 400, facilitating the production and manufacturing of the base plate 400, improving the production efficiency of the base plate 400, and improving the production quality of the base plate 400.

[0064] In some embodiments, in any two adjacent positioning slots 420, the positioning posts 411 on the facing sides of the two positioning slots 420 can be integrated, so that the same positioning post 411 can be used to limit the two circuit boards 210 respectively, effectively increasing the number of positioning slots 420 in the working slot 410, thereby improving the space utilization of the working slot 410. Furthermore, it can also increase the number of positioned lamp boards 10, improving the production efficiency of the lamp boards 10.

[0065] In some embodiments, in the horizontal plane, the working groove 410 may be provided with at least one positioning post 411 on one side of the circuit board 210. The positioning post 411 extends in a rectangular shape so that the positioning post 411 contacts the peripheral side wall of the circuit board 210, thereby increasing the contact area between the positioning post 411 and the circuit board 210, improving the limiting strength and reliability of the positioning post 411, preventing the circuit board 210 from tilting, and improving the positioning reliability of the circuit board 210.

[0066] In some embodiments, in a horizontal plane, the working groove 410 may be provided with at least two positioning posts 411 relative to one side of the circuit board 210. The two positioning posts 411 can jointly limit one side of the circuit board 210 to avoid the circuit board 210 from tilting and improve the positioning reliability of the circuit board 210.

[0067] See Figures 3 to 6 , Figure 8 , Figure 9 In this embodiment, a mounting groove 440 is provided on the base plate 400. The mounting groove 440 is used to accommodate and limit the mounting component 500, so as to position the pin 220 through the mounting component 500, realize the positioning and assembly of the pin 220 and the circuit board 210, thereby improving the production quality of the lamp board.

[0068] See Figures 3 to 9 In this embodiment, the mounting groove 440 extends along a first direction to pass through a plurality of positioning grooves 420. The mounting member 500 extends along the first direction. The mounting member 500 is provided with a plurality of positioning holes 510 corresponding to the plurality of positioning grooves 420 in the same positioning group, so that a plurality of pins 220 can be simultaneously accommodated and positioned on the mounting member 500.

[0069] After the mounting component 500 accommodates and positions the multiple pins 220, it is moved into the mounting slot 440. The peripheral sidewall of the mounting component 500 fits against the inner peripheral wall of the mounting slot 440 to limit its horizontal movement. The lower surface of the mounting component 500 fits against the bottom wall of the mounting slot 440 to limit its downward movement, thereby achieving rapid positioning of the multiple pins 220 and improving the assembly efficiency of the multiple pins 220 with the multiple circuit boards 210.

[0070] In some embodiments, there are multiple mounting members 500. The multiple mounting members 500 are respectively provided with multiple mounting slots 440 to adapt to multiple positioning groups, thereby enabling the auxiliary tooling 30 to position and assemble multiple lamp panels 10, improving the production efficiency of lamp panels 10.

[0071] In some embodiments, the mounting slot 440 may be provided corresponding to the positioning slot 420, and the mounting component 500 may be provided in multiple ways corresponding to multiple mounting slots 440, so that the mounting component 500 can be used to realize the positioning and assembly of the pin 220 and the circuit board 210.

[0072] In some embodiments, the mounting member 500 is elongated to allow it to pass sequentially through multiple positioning slots 420 within the same positioning group. This facilitates the adjacent arrangement of the multiple positioning slots 420, enabling the working slot 410 to accommodate more positioning slots 420 and improving the space utilization within the working slot 410. Furthermore, the mounting member 500 is provided with multiple positioning holes 510 corresponding to the multiple positioning slots 420, facilitating the placement and positioning of the pins 220, improving the positioning efficiency of the multiple pins 220, and increasing the production efficiency of the lamp board 10.

[0073] See Figures 3 to 9 In this embodiment, the mounting component 500 can be provided with multiple positioning holes 510 relative to any positioning slot 420, so as to realize the positioning assembly of the same circuit board 210 and multiple pins 220, thereby improving the assembly range of the auxiliary tooling 30 and improving the versatility of the auxiliary tooling 30.

[0074] In some embodiments, the mounting component 500 is provided with a positioning hole 510 relative to any positioning slot 420 for positioning and assembling the circuit board 210 and a pin 220.

[0075] In other embodiments, the mounting component 500 is provided with two positioning holes 510 relative to each positioning slot 420 to realize the positioning assembly of the circuit board 210 and the two pins 220.

[0076] In other embodiments, the mounting component 500 can be selectively replaced according to the preset number, position, and type of pinholes on the circuit board 210, so that the mounting component 500 can be accommodated in the mounting slot 440.

[0077] In related technologies, the insert pin 220 is bent. The insert pin 220 includes a first pin segment 221 and a second pin segment 222, which are arranged to intersect.

[0078] In some embodiments, the first needle segment 221 may be arranged perpendicularly to the second needle segment 222.

[0079] See Figures 6 to 9In this embodiment, the positioning hole 510 is bent. The positioning hole 510 includes a first hole segment 511 and a second hole segment 512. The first hole segment 511 is formed on the peripheral sidewall of the mounting member 500 and extends in a second direction to penetrate into the mounting member 500. The first hole segment 511 is used to accommodate the first needle segment 221 to limit the movement of the first needle segment 221 in the height direction and the first direction. The second hole segment 512 is disposed on the peripheral sidewall of the mounting member 500, the second hole segment 512 communicates with the first hole segment 511, and the second hole segment 512 extends upward to penetrate the upper surface of the mounting member 500. The second hole segment 512 is used to accommodate the second needle segment 222, and the inner peripheral wall of the second hole segment 512 can cooperate with the inner peripheral wall of the mounting groove 440 to limit the movement of the second needle segment 222 in the second direction.

[0080] After the mounting component 500 is placed in the mounting groove 440, the inner peripheral wall of the mounting groove 440 and the positioning hole 510 can limit the movement of the pin 220 in the horizontal and vertical directions, thereby facilitating the positioning of the pin 220. Furthermore, after the pin 220 is soldered to the circuit board 210, the mounting component 500 can also carry multiple lamp boards 10 out of the positioning groove 420 through the inner wall of the positioning hole 510, facilitating the movement of the lamp boards 10 to subsequent processing stations and improving the production efficiency of the lamp boards 10.

[0081] In some embodiments, positioning holes 510 are formed on at least one side wall of the mounting member 500 along the second direction to accommodate the elongated mounting member 500 and the positioning assembly.

[0082] See Figures 3 to 5 , Figure 8 , Figure 9 In this embodiment, a first clearance groove 430 is recessed on the bottom wall of the positioning groove 420 to avoid electronic components on the underside of the circuit board 210. When the circuit board 210 is pressed into the positioning groove 420, the first clearance groove 430 prevents the bottom wall of the positioning groove 420 from squeezing the electronic components on the circuit board 210, thus avoiding damage to the lamp board 10 and improving the reliability of the auxiliary tooling 30.

[0083] See Figures 3 to 5 , Figure 8 , Figure 9 In this embodiment, a third clearance groove 450 is provided on the base plate 400. In the horizontal plane, the third clearance groove 450 is provided on the periphery of the mounting groove 440 to reduce the contact area between the mounting component 500 and the inner peripheral wall of the mounting groove 440, thereby facilitating the removal of the mounting component 500 from the mounting groove 440 and improving the operating efficiency of the auxiliary tooling 30.

[0084] In some embodiments, the third clearance groove 450 may extend along the second direction to pass through multiple positioning groups in sequence, thereby effectively reducing the contact area between the positioning member and the inner peripheral wall of the multiple mounting grooves 440, reducing the friction force that the positioning member needs to overcome when it comes out of the mounting groove 440, and improving the ease of operation of the auxiliary tooling 30.

[0085] In other embodiments, there may be multiple third clearance grooves 450, which are spaced apart along the first direction to further reduce the contact area between the positioning member and the inner peripheral wall of the mounting groove 440, reduce the friction force that the positioning member needs to overcome when it comes out of the mounting groove 440, and improve the ease of operation of the auxiliary tooling 30.

[0086] See Figures 3 to 5 , Figure 8 , Figure 9 In this embodiment, a lifting hole 460 is provided on the base plate 400. The lifting hole 460 is provided on the bottom wall of the mounting groove 440 to lift the mounting component 500 and assist the mounting component 500 in disengaging from the mounting groove 440.

[0087] In some embodiments, the base plate 400 is provided with a plurality of lifting holes 460 corresponding to a plurality of mounting slots 440, so as to facilitate the lifting of a plurality of mounting components 500.

[0088] In other embodiments, the lifting hole 460 can be configured to correspond to multiple mounting slots 440, so that the mounting component 500 can rise stably to disengage from the mounting slot 440, avoid the mounting component 500 from being squeezed against the inner peripheral wall of the mounting slot 440 due to uneven force, and improve the ease with which the mounting component 500 can disengage from the base plate 400.

[0089] In other embodiments, the lifting hole 460 may be located at the junction of the mounting groove 440 and the third clearance groove 450 to facilitate the processing and manufacturing of the lifting hole 460 by the base plate 400.

[0090] See Figures 3 to 5 , Figure 8 , Figure 9 In this embodiment, the cover plate 600 is movably connected to the base plate 400. The cover plate 600 can cover the base plate 400 to press and limit the circuit board 210 within the positioning groove 420. The cover plate 600 can also be moved away from the base plate 400 to facilitate the installation and removal of the mounting component 500, the pin 220, and the circuit board 210, thereby improving the welding efficiency of the lamp board 10.

[0091] The cover plate 600 has a welding port 610 corresponding to the positioning groove 420, so that an external welding tool (not shown) can be inserted into the welding port 610 to weld the positioned and assembled pins 220 and circuit board 210, ensuring the stability and reliability of the circuit board 210 and pins 220 during welding. Furthermore, when the welding tool moves away from the circuit board 210 after welding, the cover plate 600 can prevent the circuit board 210 from jumping around with the welding tool due to solder surface tension and slag adhesion, ensuring the continuous positioning of the pins 220 and circuit board 210 and improving the welding quality of the pins 220 and circuit board 210.

[0092] In some embodiments, the cover plate 600 is provided with a plurality of welding ports 610 corresponding to a plurality of positioning grooves 420, for welding a plurality of lamp panels 10.

[0093] In other embodiments, the weld joint 610 extends along a first direction and is positioned relative to the positioning group, thereby facilitating the welding of multiple lamp panels 10 within the same positioning group by a single weld joint 610.

[0094] In other embodiments, the plurality of welding ports 610 on the cover plate 600 may be spaced apart along the second direction so that the plurality of welding ports 610 can be respectively positioned relative to the lamp plates 10 in the plurality of positioning groups, thereby ensuring the structural strength of the cover plate 600 while facilitating the welding of the plurality of lamp plates 10 on the base plate 400.

[0095] See Figures 3 to 5 , Figure 8 , Figure 9 In this embodiment, the lower surface of the cover plate 600 is recessed with a second clearance groove 620 to avoid electronic components on the upper side of the circuit board 210. This prevents the cover plate 600 from damaging the electronic components on the circuit board 210 when it is pressed against the circuit board 210, thus ensuring the reliability and stability of the circuit board 210 in the positioning assembly.

[0096] In some embodiments, the lower surface of the cover plate 600 is provided with a plurality of second clearance grooves 620 corresponding to the plurality of positioning grooves 420, so as to avoid electronic components on the upper surface of the plurality of circuit boards 210 while ensuring the stable positioning of the plurality of circuit boards 210, thereby ensuring the safety of the circuit boards 210 during positioning and assembly.

[0097] See Figure 3 , Figure 4 and Figure 8In this embodiment, the cover plate 600 and the base plate 400 are hinged together by a hinge. On the one hand, this facilitates the cover plate 600 to close to the base plate 400 around the hinge 710 and cover the base plate 400, and also facilitates the cover plate 600 to open the positioning groove 420 around the hinge 710 and away from the base plate 400. On the other hand, it facilitates the simultaneous movement of the cover plate 600 and the base plate 400 into and out of the subsequent welding station, ensuring the ease of use of the cover plate 600 and the base plate 400.

[0098] See Figure 3 , Figure 4 and Figure 8 In this embodiment, a first magnetic member 471 is embedded on the upper surface of the base plate 400. A second magnetic member 631 is embedded on the lower surface of the cover plate 600 relative to the first magnetic member 471. The first magnetic member 471 and the second magnetic member 631 can generate a magnetic attraction force to limit the cover plate 600 to the base plate 400.

[0099] When the cover plate 600 is placed on the base plate 400, the first magnetic suction member 471 and the second magnetic suction member 631 ensure that the cover plate 600 is stably and reliably placed on the base plate 400. During the movement of the auxiliary tooling 30, the cover plate 600 is prevented from moving away from the base plate 400, and the circuit board 210 is prevented from falling out of the positioning slot 420, thus ensuring the positioning accuracy and reliability of the circuit board 210 and the production quality of the lamp board 10.

[0100] In some embodiments, there may be multiple first magnetic attractors 471, which are spaced apart and disposed on the periphery of the base plate 400. There may also be multiple second magnetic attractors 631 corresponding to the multiple first magnetic attractors 471, which are spaced apart and disposed on the periphery of the cover plate 600. The multiple first magnetic attractors 471 and the multiple second magnetic attractors 631 can improve the connection stability and reliability between the cover plate 600 and the base plate 400.

[0101] In other embodiments, the first magnetic chuck 471 may be disposed at the end of the base plate 400 away from the hinge axis. The second magnetic chuck 631 may be disposed at the end of the cover plate 600 away from the hinge axis. The first magnetic chuck 471 and the second magnetic chuck 631 can cooperate with the hinge axis to stably and reliably limit the cover plate 600 to the base plate 400, improve the connection strength between the cover plate 600 and the base plate 400, and prevent the cover plate 600 from moving away from the base plate 400 during movement, so that the circuit board 210 is stably pressed in the positioning groove 420 and positioned and assembled with the pin 220.

[0102] See Figure 3 , Figure 4 and Figure 8In this embodiment, a positioning protrusion 472 is provided on the upper surface of the base plate 400. A positioning groove 632 is provided on the lower surface of the cover plate 600 relative to the positioning protrusion 472. When the cover plate 600 is placed on the base plate 400, the positioning protrusion 472 can extend into the positioning groove 632 to limit the movement of the cover plate 600 relative to the base plate 400 in the horizontal direction, thereby preventing the cover plate 600 from moving away from the base plate 400, so that the cover plate 600 can be stably pressed on the base plate 400, and preventing the circuit board 210 from falling out of the positioning groove 420.

[0103] In some embodiments, the positioning protrusion 472 may be disposed at the end of the base plate 400 away from the hinge axis. The positioning groove 632 may be disposed at the end of the cover plate 600 away from the hinge axis. When the cover plate 600 rotates around the hinge member 710 to cover the base plate 400, the positioning protrusion 472 can extend into the positioning groove 632 to ensure the connection strength between the cover plate 600 and the connecting member, prevent the cover plate 600 from separating from the base plate 400 due to accidental factors, and improve the reliability and stability of the auxiliary tooling 30.

[0104] In some embodiments, the hinge 710 is not required. Multiple positioning protrusions 472 may be present. These protrusions 472 are spaced apart on the periphery of the base plate 400. Multiple positioning grooves 632 may correspond to these protrusions 472. These grooves 632 are spaced apart on the periphery of the cover plate 600. The protrusions 472 and grooves 632 guide the cover plate 600 and base plate 400 to move closer together, allowing the cover plate 600 to press the circuit board 210 into the positioning groove 420, thus achieving the positioning and assembly of the circuit board 210 and the pins 220.

[0105] Figure 10 This is a structural schematic diagram of the base of this utility model. Figure 11 This is a structural diagram of the lifting and installation component after the lamp panel of this utility model has been welded. Figure 12 Figure 11 Enlarged view of the structure at point C.

[0106] See Figure 3 , Figure 4 , Figure 8 , Figures 10 to 12 In this embodiment, the auxiliary tooling 30 also includes a base 800. The base 800 is located below the base plate 400. A lifting column 810 is provided on the base relative to the lifting hole 460. When the base plate 400 is attached to the base 800, the lifting column 810 can pass through the lifting hole 460 and extend into the mounting groove 440 to lift the mounting component 500.

[0107] After the pin 220 is soldered to the circuit board 210, the cover plate 600 is opened. Then, the base plate 400 and the base 800 are moved towards each other so that the lifting column 810 passes through the lifting hole 460 and extends into the mounting groove 440, thereby lifting the mounting component 500 in the mounting groove 440. After the mounting component 500 is lifted and removed from the mounting groove 440, it is easier to separate the lamp board 10 on the mounting component 500, thus improving the production efficiency of the lamp board 10.

[0108] See Figures 10 to 12 In this embodiment, the base 800 is provided with multiple lifting columns 810 corresponding to multiple lifting holes 460, so that the base 800 can lift multiple mounting parts 500 at the same time, which facilitates the multiple mounting parts 500 to quickly detach from the base plate 400, improves the detachment efficiency of the lamp board 10, and improves the production efficiency of the lamp board 10.

[0109] In this embodiment, a guide block 820 protrudes from the circumference of the upper surface of the base 800. A guide notch 473 is provided on the circumference of the base plate 400. The guide block 820 is disposed opposite to the guide notch 473. When the base plate 400 is attached to the base 800, the guide block 820 can extend into the guide notch 473 so that the lifting column 810 is aligned with the lifting hole 460.

[0110] When the base plate 400 and the base 800 move towards each other, the guide notch 473 guides the movement of the guide block 820 to achieve positioning between the lifting column 810 and the lifting hole 460, thereby enabling the lifting column 810 to be stably inserted into the lifting hole 460, improving the assembly efficiency between the base plate 400 and the base 800, and improving the lifting efficiency of the lamp plate 10.

[0111] In some embodiments, guide blocks 820 are respectively provided on opposite sides of the upper surface of the base 800. Two guide notches 473 are provided on the periphery of the base plate 400 corresponding to the two guide blocks 820, so as to facilitate further positioning and assembly of the base plate 400 and the base 800 and improve the assembly efficiency of the base plate 400 and the base 800.

[0112] See Figures 1 to 12 This utility model provides an auxiliary tooling 30, which is used to position and assemble the pin 220 and the circuit board 210, so as to facilitate the subsequent soldering of the pin 220 and the circuit board 210.

[0113] When multiple lamp boards 10 need to be positioned and assembled, multiple pins 220 are placed into the positioning holes 510 of multiple mounting parts 500, and then the multiple mounting parts 500 are placed into the mounting grooves 440 to achieve positioning of the pins 220. Then, multiple circuit boards 210 are placed into the positioning grooves 420, so that the inner peripheral wall of the positioning grooves 420 abuts against and limits the circuit boards 210, and the pins 220 pass through the pin holes on the circuit boards 210.

[0114] Then, the cover plate 600 is rotated around the hinge axis to cover the base plate 400, thereby pressing the circuit board 210 into the positioning groove 420, realizing the rapid and accurate mutual positioning and assembly of the circuit board 210 and the pin 220.

[0115] After the circuit board 210 and the pin 220 are positioned and assembled, the base plate 400, the cover plate 600 and the lamp board 10 inside are moved to the welding station so that the external welding device can weld the pin 220 to the circuit board 210 through the welding port 610.

[0116] After the pin 220 is soldered to the circuit board 210, the cover plate 600 is opened, and the base plate 400 is moved toward the base 800. The guide block 820 is matched with the guide notch 473, and the lifting column 810 extends into the mounting groove 440 through the lifting hole 460 to lift the mounting part 500, so that the mounting part 500 is disengaged from the mounting groove 440 and the lamp board 10 is disengaged from the positioning groove 420, thereby facilitating the subsequent use of the lamp board 10 and improving the assembly efficiency of the lamp board 10.
