Description

Technical Field

[0001] This utility model relates to the field of 3C product processing technology, specifically to a carrier for welding electronic products. Background Technology

[0002] Electronic product soldering carriers are tools used to fix and support electronic components and circuit boards, ensuring accuracy and stability during the soldering process. They are widely used in PCB assembly, reflow soldering, wave soldering, and manual soldering to improve production efficiency and guarantee soldering quality.

[0003] A search revealed Chinese patent publication number CN213135668U, which discloses a general-purpose electronic product welding carrier, including a base plate and a supporting body disposed on the base plate. The supporting body has a bottom block for placing the weldment. A receiving cavity extending to the upper surface is formed on one side of the bottom block. A slider is disposed within the receiving cavity, the width of which is smaller than the width of the receiving cavity, allowing the slider to move towards or away from the bottom block. A positive pressure block is disposed at the upper end of the slider. A limiting block is disposed on the supporting body. When the slider is closest to the bottom block, the opposite sides of the weldment located on the bottom block are clamped by the positive pressure block and the limiting block, respectively. However, this welding carrier also has the following problems:

[0004] In the existing technology, due to the large variety of circuit board (PCB) types, including single-sided boards, double-sided boards, multilayer boards and flexible circuit boards, these circuit boards have different shapes, sizes and models, making it difficult to adaptively adjust the clamping force during the fixing process. This leads to the risk of damage to the circuit board or components, reduced soldering accuracy, and even increased impact on product quality.

[0005] Based on this, the present invention designs a carrier for welding electronic products to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a carrier for welding electronic products.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A carrier for welding electronic products includes a worktable, a lateral moving mechanism, a longitudinal moving mechanism, a clamping mechanism, and a positioning and protection mechanism. The top of the worktable is fixedly connected to the lateral moving mechanism. Two longitudinal moving mechanisms are symmetrically distributed at the left and right ends of the lateral moving mechanism. Two clamping mechanisms are symmetrically distributed at the top of the longitudinal moving mechanism. The bottom of the clamping mechanism is threadedly connected to the output end of the longitudinal moving mechanism. The top of the lateral moving mechanism is fixedly connected to the positioning and protection mechanism.

[0009] The lateral movement mechanism includes a lateral movement table, a threaded rod, and a slider. The bottom of the lateral movement table is fixedly connected to the top of the worktable. The threaded rod is rotatably connected inside the lateral movement table, and the slider is threadedly connected to the outside of the threaded rod. The slider is slidably connected inside the lateral movement table.

[0010] Furthermore, the longitudinal moving mechanism includes a longitudinal moving stage and positive and negative threaded rods. The bottom of one longitudinal moving stage is fixedly connected to the top of the slider, and the bottom of the other longitudinal moving stage is fixedly connected to the top of the transverse moving stage. The positive and negative threaded rods are rotatably connected inside the longitudinal moving stage, and limit grooves are provided on both sides of the inner wall of the longitudinal moving stage.

[0011] Furthermore, the clamping mechanism includes a right-angle frame, a limiting block, and a clamping assembly. The bottom of the right-angle frame is threaded to the outside of the positive and negative threaded rods. Limiting blocks are fixedly connected to both sides of the bottom of the right-angle frame. The outer side of the limiting block is slidably connected to the inside of the limiting groove. A clamping assembly is fixedly connected to the outer side of the top of the right-angle frame.

[0012] Furthermore, the clamping assembly includes a fixed cylinder, a sliding rod, a silicone head, and a spring. The outer wall of the fixed cylinder is fixedly connected to the outer wall of the right-angle frame. The inner wall of the fixed cylinder is slidably connected to the sliding rod. The outer wall of the sliding rod is slidably connected to the inside of the right-angle frame. The outer end of the sliding rod is fixedly connected to the silicone head. One end of the spring is fixedly connected to the inner wall of the fixed cylinder, and the other end of the spring is fixedly connected to the end of the sliding rod closer to the fixed cylinder.

[0013] Furthermore, the positioning and protection mechanism includes columns, sliding frames, positioning components, heat insulation frames, and lifting components. The bottoms of multiple columns are fixedly connected to the top of the horizontal moving platform. Sliding frames are slidably connected to the outer walls of multiple columns. Sliding grooves are respectively opened in the middle of the two adjacent sides of the sliding frames. Positioning components are slidably connected to the middle of the two adjacent sides of the sliding frames. The output end of the positioning components is fixedly connected to the heat insulation frame. The bottom of the sliding frames is fixedly connected to the lifting components.

[0014] Furthermore, the positioning component includes an extension rod and an anti-detachment block. The outer walls of the two extension rods are slidably connected to the inside of the two slide grooves, and the outer walls of the extension rods are slidably connected to two anti-detachment blocks. The adjacent sides of the two anti-detachment blocks are slidably connected to the inner and outer sides of the sliding frame, and the outer wall of the heat insulation frame is fixedly connected to the adjacent ends of the two extension rods.

[0015] Furthermore, the lifting assembly includes a sliding ring and a set screw. The sliding ring is slidably connected to the outer wall of the column, the top of the sliding ring is fixedly connected to the bottom of the sliding frame, and the set screw is threadedly connected to the inside of the sliding ring.

[0016] Furthermore, the end of the set screw near the column has a rough surface, which contacts the outer wall of the column.

[0017] Compared with the prior art, the advantages of this utility model are as follows: 1. The clamping mechanism uses the reverse force generated when the clamping rod contacts the circuit board to make the clamping rod slide into the fixed cylinder and compress the spring. The reverse force of the spring makes the clamping rod fit tightly against the circuit board, which can adapt to circuit boards of different sizes and shapes, and improve the versatility and efficiency of the welding operation. After the initial clamping, the drive rod is rotated, and the positive and negative thread grooves on it make the fastening ring tighten the fixed cylinder, which increases the friction between the inner wall of the fixed cylinder and the outer wall of the clamping rod, thereby locking the clamping mechanism and ensuring the stability of electronic products during welding, so as to improve the welding accuracy.

[0018] 2. By pulling the heat insulation frame, the extension rod moves horizontally on the sliding frame groove, allowing the heat insulation frame to be precisely positioned directly above the part of the circuit board to be soldered. Then, by rotating the set screw to unlock the sliding ring, the sliding frame can be lowered together with the sliding ring, causing the heat insulation frame to descend until its bottom soft layer contacts the circuit board, ensuring that the part to be soldered is located in the inner space of the heat insulation frame. Then, rotate the set screw in the opposite direction to make it contact the column and fix the position of the sliding ring through friction. In this way, the heat insulation effect of the heat insulation frame is used to reduce the impact of the soldering temperature on the non-soldering area during soldering, while achieving precise positioning of the soldering area and preventing the soldering position from shifting.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the plan view.

[0031] In some embodiments, please refer to the accompanying drawings. Figures 1-7 A welding carrier for electronic products includes a workbench 1, a transverse moving mechanism 2, a longitudinal moving mechanism 3, a clamping mechanism 4, and a positioning and protection mechanism 5. The top of the workbench 1 is fixedly connected to the transverse moving mechanism 2. Two longitudinal moving mechanisms 3 are symmetrically distributed at the left and right ends of the transverse moving mechanism 2. Two clamping mechanisms 4 are symmetrically distributed at the top of the longitudinal moving mechanism 3, and the bottom of the clamping mechanism 4 is located at both ends of the longitudinal moving mechanism 3. The top of the transverse moving mechanism 2 is fixedly connected to the positioning and protection mechanism 5.

[0032] The transverse moving mechanism 2 includes a transverse moving table 201, a threaded rod 202, and a slider 203. The bottom of the transverse moving table 201 is fixedly connected to the top of the worktable 1. The threaded rod 202 is rotatably connected inside the transverse moving table 201. The slider 203 is threadedly connected to the outside of the threaded rod 202. The slider 203 is slidably connected inside the transverse moving table 201.

[0033] The longitudinal moving mechanism 3 includes a longitudinal moving stage 301 and a positive and negative threaded rod 302. The bottom of one longitudinal moving stage 301 is fixedly connected to the top of the slider 203, and the bottom of the other longitudinal moving stage 301 is fixedly connected to the top of the transverse moving stage 201. The positive and negative threaded rod 302 is rotatably connected inside the longitudinal moving stage 301. Limiting grooves 303 are provided on both sides of the inner wall of the longitudinal moving stage 301.

[0034] Furthermore, before soldering circuit boards and other components in electronic products, rotating the threaded rod 202 causes the slider 203 to slide from one end of the transverse moving table 201 to the other, thereby moving one of the longitudinal moving mechanisms 3 closer to the other, thus adjusting the transverse spacing of the clamping mechanisms 4. Then, rotating the positive and negative threaded rods 302 causes the two clamping mechanisms 4 to move towards the center simultaneously, thereby adjusting the longitudinal spacing of the clamping mechanisms 4 to accommodate circuit boards of different sizes. The clamping mechanisms 4 then adaptively clamp and fix the circuit board at the four corners, ensuring that the circuit board remains stable during subsequent soldering. Finally, the positioning and protection mechanism 5 precisely positions and protects the parts of the circuit board that need to be soldered, preventing the high temperature generated during soldering from causing heat deformation in other parts of the circuit board.

[0035] The clamping mechanism 4 includes a right-angle frame 401, a limiting block 402, and a clamping assembly. The bottom of the right-angle frame 401 is threaded to the outside of the positive and negative threaded rod 302. The limiting blocks 402 are fixedly connected to both sides of the bottom of the right-angle frame 401. The outer side of the limiting block 402 is slidably connected to the inside of the limiting groove 303. The clamping assembly is fixedly connected to the outer side of the top of the right-angle frame 401.

[0036] The clamping assembly includes a fixed cylinder 403, a slide rod 404, a silicone head 405, and a spring 406. The outer wall of the fixed cylinder 403 is fixedly connected to the outer wall of the right-angle bracket 401. The inner wall of the fixed cylinder 403 is slidably connected to the slide rod 404. The outer wall of the slide rod 404 is slidably connected to the inside of the right-angle bracket 401. The outer end of the slide rod 404 is fixedly connected to the silicone head 405. One end of the spring 406 is fixedly connected to the inner wall of the fixed cylinder 403, and the other end of the spring 406 is fixedly connected to the end of the slide rod 404 near the fixed cylinder 403.

[0037] Furthermore, when the silicone head 405 on the slide bar 404 of the clamping mechanism 4 contacts the four corners of the circuit board, the reverse force generated during the contact drives the slide bar 404 to slide into the fixed cylinder 403 and compresses the spring 406. In this way, the reverse force of the spring 406 allows the silicone head 405 on the slide bar 404 to fit tightly against the outside of the circuit board, thus adapting to circuit boards of different sizes and shapes. Moreover, by simultaneously clamping the four corners of the electronic components, the stability of the electronic components is ensured after clamping.

[0038] The positioning and protection mechanism 5 includes columns 501, sliding frames 502, positioning components, heat insulation frames 506, and lifting components. The bottoms of multiple columns 501 are fixedly connected to the top of the horizontal moving platform 201. Sliding frames 502 are slidably connected to the outer walls of multiple columns 501. Sliding grooves 503 are respectively opened in the middle of the two adjacent sides of the sliding frames 502. Positioning components are slidably connected to the middle of the two adjacent sides of the sliding frames 502. The output end of the positioning components is fixedly connected to the heat insulation frame 506. The bottom of the heat insulation frame 506 is provided with a silicone rubber pad, which prevents the bottom of the heat insulation plate from damaging the circuit board while having good heat insulation performance. The bottom of the sliding frame 502 is fixedly connected to the lifting components.

[0039] The positioning assembly includes extension rods 504 and anti-detachment blocks 505. The outer walls of the two extension rods 504 are slidably connected to the inside of the two slide grooves 503, and the outer walls of the extension rods 504 are slidably connected to the two anti-detachment blocks 505. The adjacent sides of the two anti-detachment blocks 505 are slidably connected to the inner and outer sides of the sliding frame 502, and the outer wall of the heat insulation frame 506 is fixedly connected to the adjacent ends of the two extension rods 504.

[0040] The lifting assembly includes a sliding ring 507 and a set screw 508. The sliding ring 507 is slidably connected to the outer wall of the column 501. The top of the sliding ring 507 is fixedly connected to the bottom of the sliding frame 502. The set screw 508 is threadedly connected to the inside of the sliding ring 507. The end of the set screw 508 near the column 501 is provided with a rough surface and contacts the outer wall of the column 501.

[0041] Furthermore, before soldering, according to the position of the part of the circuit board to be soldered, the heat insulation frame 506 is pulled. Through the sliding of the two extension rods 504 on the grooves 503 of the sliding frame 502, the extension rods 504 can move freely horizontally on the horizontal plane where the sliding frame 502 is located. The positions of the two extension rods 504 determine the horizontal and vertical positions of the heat insulation frame 506 on the horizontal plane, respectively. This allows the heat insulation frame 506 to move directly above the part of the circuit board to be soldered. Then, by rotating the set screw 508, the set screw 508 moves outward from inside the sliding ring 507, allowing the entire sliding ring 507 to slide. This achieves the vertical orientation adjustment of the sliding frame 502, thus through the transmission action of the extension rods 504. The heat insulation frame 506 is vertically adjusted until the bottom soft layer of the heat insulation frame 506 contacts the circuit board, so that the part to be soldered is in the inner space of the heat insulation frame 506. Then, the set screw 508 is rotated in the opposite direction, so that the set screw 508 moves into the sliding ring 507 and then contacts the outer surface of the column 501 through the rough surface of the other end of the set screw 508. Then, the position of the sliding ring 507 is fixed by friction. In this way, the vertical position of the entire sliding frame 502 and the heat insulation frame 506 is fixed by fixing the four corners. Then, during the soldering, the heat insulation effect of the heat insulation frame 506 reduces the impact of the soldering temperature on the parts that do not need to be soldered, thus playing a protective role. At the same time, it is also convenient to accurately position the soldering area and prevent the soldering position from shifting.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
