[0028] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0029] Figure 1 This is a schematic diagram of the structure of a tool for welding a microphone motherboard provided by an embodiment of the present invention. Figure 1 The tooling includes a handle 1, a connecting rod 2, a spring 3, a positioning rod 4, a first body 5, a second body 6, a side plate 7, a side plate fixing screw 8, a wire clamping plate 9, a wire clamping plate fixing screw 10, a bottom plate 11, and a fixing screw 12 corresponding to the first body.

[0030] Among them, the handle 1 and the spring 3 are combined with the positioning rod 4 through the connecting rod 2, the positioning rod 4 is fixedly connected to the second main body 6, the first main body 5 is fixed to the base plate 11 through the fixing screws 12 corresponding to the first main body, the side panel 7 is fixed to the first main body 5 through the side panel fixing screws 8, and the wire clamping plate 9 is fixed to the side panel 7 through the wire clamping plate fixing screws 10.

[0031] refer to Figure 1 Specifically, the assembly steps of the tooling for welding the microphone mainboard provided in this embodiment can be: first, the first body 5 can be fixed to the bottom plate 11 using the fixing screws 12 corresponding to the two first bodies; then, the spring 3 is put on the positioning rod 4, and the positioning rod 4 and the handle 1 are assembled with the connecting rod 2 to form a set of positioning rod assemblies; further, the positioning rod 4 is passed through the first body 5, and the head of the positioning rod 4 is used to fix the second body 6; finally, the side panel 7 is fixed to the first body 5 with the side panel fixing screws 8, and the wire clamping plate 9 is fixed to the side panel 7 with the wire clamping plate fixing screws 10.

[0032] In this embodiment, in addition to welding, threading can also be used to fix the positioning rod 4 to the second body 6. In one example, the head of the positioning rod 4 is provided with threads, and the head of the positioning rod 4 is on the side close to the second body 6; the positioning rod 4 is fixedly connected to the second body 6 via the threads on the head.

[0033] That is, a thread can be set on the head of the positioning rod 4, and a thread can be set inside the second body 6. The positioning rod 4 can be engaged with the thread inside the second body 6 by rotation, thereby achieving fixation between the positioning rod 4 and the second body 6, so that the handle 1 can drive the positioning rod 4 to move, and then the positioning rod 4 drives the second body 6 to move.

[0034] Compared with welding, using the thread on the head of the positioning rod 4 to fix the second body 6 can reduce the difficulty of the process and make the tooling structure flexible, which is convenient for subsequent disassembly of the tooling to perform maintenance on various components.

[0035] Furthermore, in this embodiment, in addition to welding, threading can also be used to secure the handle 1 to the positioning rod 4. In one example, the surface of the connecting rod 2 is provided with threads, and the connecting rod 2 is connected to the handle 1 via the surface threads, and is also connected to the positioning rod 4 via the surface threads.

[0036] That is, threads can be set on the surface of the connecting rod 2, threads can be set inside the handle 1, and threads can be set inside the positioning rod 4. The connecting rod 2 can be rotated to engage with the threads inside the handle 1, thereby achieving fixation between the connecting rod 2 and the handle 1, and can be rotated to engage with the threads inside the positioning rod 4, thereby achieving fixation between the connecting rod 2 and the positioning rod 4.

[0037] Compared with the welding method, the use of threads on the surface of the connecting rod 2 to fix the handle 1 and the positioning rod 4 can reduce the difficulty of the process and make the tooling structure flexible, which is convenient for subsequent disassembly of the tooling to perform maintenance on various components.

[0038] Figure 2This is a main view of a tool provided by an embodiment of the utility model after assembly. Figure 3 This is a left side view of a tool provided by an embodiment of the utility model after assembly. Figure 4 This is a top view of a tooling assembly provided by an embodiment of the present invention. Figure 5 This is a schematic diagram of a tooling assembly provided by an embodiment of the present invention. Figure 2-Figure 5 As shown, the assembled tooling is shown from different perspectives.

[0039] The tooling provided in this embodiment, after assembly is completed, the handle 1 can push the compression spring forward and drive the positioning rod 4 to move, and then the positioning rod 4 can drive the second body 6 to slide forward on the bottom plate 11, so that the gap between the first body 5 and the second body 6 becomes larger, leaving an appropriate gap, so that the microphone mainboard is placed in the gap between the first body 5 and the second body 6, and the handle is released to continuously apply a backward force to the second body 6 through the elastic force of the spring 3, so that the microphone mainboard is clamped between the first body 5 and the second body 6.

[0040] In a specific embodiment, a sliding groove is provided on the bottom plate 11 , and the handle 1 is used to drive the second body 6 to move on the sliding groove to adjust the clamping space between the first body 5 and the second body 6 .

[0041] Among them, the bottom plate 11 can be provided with a hollow sliding groove, the length of the sliding groove can be determined according to the expansion and contraction scale of the spring 3, and accordingly, the bottom of the second body 6 can be provided with a protruding structure, which can be embedded in the sliding groove.

[0042] Specifically, the handle 1 can compress the spring 3, driving the second body 6 to move on the sliding groove. By moving the second body 6, the clamping space between the first body 6 and the second body 6 can be changed. By providing the sliding groove on the bottom plate 11, the movement of the second body 6 can be made smoother. Compared with directly sliding the second body 6 on the bottom plate 11, this method can avoid frequent friction between the second body 6 and the bottom plate 11, thereby ensuring the service life of the second body 6 and the bottom plate.

[0043] The tooling provided in this embodiment, after assembly is completed, can fix the microphone mainboard through the first main body 5 and the second main body 6 , and can also fix the wiring harness that needs to be welded to the microphone mainboard through the side panel 7 and the wire clamping plate 9 .

[0044] In a specific embodiment, the first body 5 and the second body 6 are used to clamp and fix the microphone mainboard; the side panel 7 is provided with a wire harness slot, the wire harness slot is used to place the wire harness, and the wire clamping plate 9 is used to fix the wire harness in the wire harness slot.

[0045] Among them, the microphone main board can be clamped and fixed between the first body 5 and the second body 6, and a wire harness slot can be provided on the side panel 7. The wire harness that needs to be welded to the microphone main board can be placed in the wire harness slot. The wire clamping plate 9 can limit the wire harness in the wire harness slot to achieve the purpose of fixing the wire harness in the wire harness slot.

[0046] The microphone mainboard can be fixed by the cooperation of the first body 5 and the second body 6, and the wiring harness can be fixed by the cooperation of the side plate 7 and the wire clamping plate 9, so as to facilitate the subsequent automatic welding equipment to perform automatic welding.

[0047] It should be noted that in order to facilitate the subsequent welding process of the automatic welding equipment, when the microphone mainboard is placed between the first body 5 and the second body 6, it is necessary to ensure that the welding surface of the microphone mainboard is placed upward, and it is necessary to ensure that the welding end of the wire harness is placed upward, so that the subsequent automatic welding equipment can weld the welding end of the wire harness to the welding surface of the microphone mainboard.

[0048] In this embodiment, in order to ensure the position stability of the microphone mainboard between the first body 5 and the second body 6, in addition to clamping the microphone mainboard by the first body 5 and the second body 6, corresponding symmetrical card slots can also be set in the first body 5 and the second body 6. The symmetrical card slots can limit the position of the microphone mainboard to achieve the purpose of fixing the microphone mainboard.

[0049] In one example, a motherboard slot is provided on the surface of the first body 5, and a motherboard slot is provided on the surface of the second body 6. The motherboard slot of the first body 5 and the motherboard slot of the second body are symmetrically positioned; the first body 5 and the second body 6 clamp and fix the microphone motherboard through the symmetrical motherboard slots.

[0050] That is, a motherboard slot can be provided on the surface of the first body 5 facing the second body 6, and a motherboard slot can be provided on the surface of the second body 6 facing the first body 5, with the two motherboard slots being symmetrically positioned. The microphone motherboard can be placed between the first body 5 and the second body 6, with the two sides of the microphone motherboard respectively embedded in the two symmetrical motherboard slots.

[0051] Through the above example, the position of the microphone mainboard can be further restricted by the symmetrical mainboard slots, thereby ensuring the stability of the position of the microphone mainboard and preventing the position of the microphone mainboard from changing.

[0052] In this embodiment, in addition to limiting the microphone mainboard through symmetrical mainboard slots, symmetrical raised clamping structures can also be set on the first main body 5 and the second main body 6 respectively to limit the microphone mainboard through the raised clamping structure and ensure the stability of the microphone mainboard position.

[0053] Considering that the welding surface of the microphone main board is facing upward, in order to facilitate subsequent automatic welding, the microphone main board clamped by the first body 5 and the second body 6 can be as close to the top as possible, so that the welding surface is as close as possible to the top surface of the first body 5 and the second body 6, which facilitates subsequent welding and increases the convenience of clamping and fixing the microphone main board.

[0054] Optionally, the mainboard slot of the first body 5 is located at the top edge of the surface facing the second body 6 , and the mainboard slot of the second body 6 is located at the top edge of the surface facing the first body 5 .

[0055] Specifically, a motherboard slot is provided at the top edge of the surface of the first body 5 facing the second body 6, and a motherboard slot is provided at the top edge of the surface of the second body 6 facing the first body 5. By placing the motherboard slot near the top edge of the surface, the soldering surface of the fixed microphone motherboard can be positioned as high as possible, facilitating subsequent soldering.

[0056] In this embodiment, the wire harness can be smoothly placed on the wire harness slot of the side panel 7, and then the wire clamping plate 9 limits the position of the wire harness and fixes the wire harness.

[0057] In one example, the harness slot is provided at the side edge of the side panel 7. Figure 1 As shown, the harness slot on the side panel 7 can be located at the side edge of the side panel 7. The harness can be placed into the harness slot from bottom to top, with the welding end of the harness facing upward. By arranging the harness slot at the side edge of the side panel 7, the welding end of the harness can face the automatic welding equipment, facilitating subsequent automatic welding.

[0058] In this embodiment, the wire clamping plate 9 may be a retractable structure that can block the wire harness in the wire harness clamping slot by extending, or may be a rotatable structure that can block the wire harness in the wire harness clamping slot by rotating.

[0059] In one example, the wire clamping plate 9 is a rotatable structure on the side plate 7 , and the wire clamping plate 9 is rotated to a position to fix the wire harness after the wire harness is placed in the wire harness slot.

[0060] Among them, the wire clamping plate 9 can be rotated on the side panel 7. Before the wiring harness is placed in the wiring harness slot, the wire clamping plate 9 can be rotated to a position that does not block the wiring harness slot. Before the wiring harness is placed in the wiring harness slot, the wire clamping plate 9 can be rotated to a position that blocks the wiring harness slot, so as to achieve the purpose of limiting the wiring harness in the wiring harness slot and fix the wiring harness.

[0061] By setting the wire clamping plate 9 as a rotatable structure, the wire clamping plate 9 can be flexibly rotated to fix the position of the wire harness, which is convenient for subsequent automatic welding equipment to perform welding.

[0062] Optionally, the first body 5, the second body 6, and the side panels 7 are made of stainless steel, and the wire clip 9 is made of nylon. Specifically, the first body 5, the second body 6, and the side panels 7 can be made of stainless steel 9Cr18; and the wire clip 9 can be made of nylon (black) PA66 or nylon (white) PA66.

[0063] By setting the material of each main body and side panel to stainless steel, the structural stability and durability of the tooling can be improved, and by setting the wire clamping plate to nylon, the flexible rotation of the wire clamping plate can be achieved.

[0064] In this embodiment, the side panel fixing screws 8 may be M4 screws, the wire clamping plate fixing screws 10 may be M3 screws, and the fixing screws 12 corresponding to the first body may be M4 screws.

[0065] The utility model has the following technical effects: by providing a tool consisting of a handle, a connecting rod, a spring, a positioning rod, a first main body, a second main body, a side panel, a side panel fixing screw, a wire clamping plate, a wire clamping plate fixing screw, a bottom plate, and fixing screws corresponding to the first main body, wherein the handle and the spring are combined with the connecting rod and the positioning rod, the positioning rod is fixedly connected to the second main body, the first main body is fixed to the bottom plate by corresponding fixing screws, the side panel is fixed to the first main body by the side panel fixing screws, and the wire clamping plate is fixed to the side panel by the wire clamping plate fixing screws. The tool can fix the microphone main board through the cooperation of the first main body and the second main body, and fix the wiring harness through the cooperation of the wire clamping plate and the side panel, which is convenient for automatic welding equipment to continuously weld the microphone main board and the wiring harness, thereby improving the welding accuracy and welding efficiency of the microphone main board, and solving the problems of poor welding quality consistency, poor stability, inconvenience for mass production, and low welding efficiency in the prior art.
