Description

Technical Field

[0001] This utility model belongs to the field of electronic assembly technology, and specifically relates to an electronic assembly tooling. Background Technology

[0002] Electronic components are the basic elements in electronic circuits. They are usually individually packaged and have two or more leads or metal contacts. Electronic components must be interconnected to form an electronic circuit with a specific function. Therefore, during the assembly of electronic components, specific work is required to limit their movement to prevent bending or even breakage of the contacts due to misalignment.

[0003] Chinese patent CN215588982U discloses a relay assembly fixture. A push block drives the relay to the left, and the shape of the locking block matches the shape of the wiring harness while limiting the path of the harness's leftward movement, assembling the relay and the harness. The sliding tube further stabilizes the push rod's leftward movement, enabling rapid relay assembly. However, this assembly fixture for electronic components has the following problems in practical use: although the sliding push block pushes the electronic component for adaptation, this fixture cannot limit the movement of electronic components with different specifications, limiting the assembly operation within a specific range. Furthermore, the positioning mechanism of this fixture cannot guarantee stability during assembly, thus reducing the convenience of positioning during assembly.

[0004] Therefore, we propose a new electronic assembly fixture to address the problems mentioned above. Utility Model Content

[0036] To make the objectives, technical solutions, design methods, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0037] like Figure 1-6As shown, this utility model provides an electronic assembly fixture, including an assembly platform 1. An adjustment guide groove 2 is provided at the center of the assembly platform 1. Four sets of positioning locking seats 11, arranged in a rectangle, are provided at the top of the adjustment guide groove 2 to fix the four corners of plate-type electronic components. To solve the problem that the assembly range of the existing assembly platform 1 cannot be adjusted, a first adjustment component and a second adjustment component are provided inside the adjustment guide groove 2. The first and second adjustment components are convexly connected, and the positioning locking seats 11 are convexly connected to the second adjustment component. The first adjustment component is used to adjust the positioning locking seats 11 to move along a first direction, and the second adjustment component is used to adjust the positioning locking seats 11 to move along a second direction. The first and second directions are perpendicular. By using the first and second adjustment components inside the assembly platform 1 to drive the positioning locking seats 11 for adjustment, it can be adapted to electronic components of different specifications. The positioning locking seats 11 limit the electronic components, preventing them from shifting during assembly and improving the assembly accuracy of the electronic components.

[0038] Specifically, in this embodiment, the first adjustment component includes two first bidirectional threaded rods 4 symmetrically arranged inside the adjustment guide groove 2. Each first bidirectional threaded rod 4 passes through the assembly platform 1 and is rotatably connected to the assembly platform 1 via a bearing. An adjustment cross plate 3 is provided on each of the first bidirectional threaded rods, spanning the two first bidirectional threaded rods 3 and threadedly connected to them. Two adjustment cross plates 3 are provided, symmetrically arranged around the center of each first bidirectional threaded rod 3. One end of each of the two first bidirectional threaded rods 4 is provided with a wheel for rotating the first bidirectional threaded rod 4 under external force. The other ends of the two first bidirectional threaded rods 4 are connected via a sprocket mechanism 5. The sprocket mechanism 5 consists of a driving sprocket, a driven sprocket, and a chain. The driving sprocket and driven sprocket are respectively fixedly installed at the ends of the two first bidirectional threaded rods 4 and connected via chain drive. When one first bidirectional threaded rod 4 is rotated, the driving sprocket drives the driven sprocket to rotate via the chain, thereby causing the other first bidirectional threaded rod 4 to rotate synchronously.

[0039] In the above, the adjusting horizontal plate 3 is provided with ear plates at both ends, and the ear plates are fixedly connected to the adjusting horizontal plate 3; the second adjusting assembly includes two second bidirectional threaded rods 8, each of the second bidirectional threaded rods 8 is respectively provided on one of the adjusting horizontal plates 3, and one end of the second bidirectional threaded rod 8 is rotatably connected to one ear plate through a bearing, and the other end of the second bidirectional threaded rod 8 passes through the other ear plate and extends to the outside of the ear plate; each of the second bidirectional threaded rods 8 is fitted with two movable sliders, and the two movable sliders are symmetrically arranged along the center line of the second bidirectional threaded rod 8; the movable sliders are threadedly connected to the second bidirectional threaded rods 8; the positioning locking seat 11 is fixedly provided on the top of the movable slider.

[0040] When adjusting the two movable sliders, in this embodiment, an adjusting shaft 6 is connected to the top side of the assembly platform 1 via a rotating shaft bracket. The adjusting shaft 6 is rotatably connected to the rotating shaft bracket. A first bevel gear 7 is sleeved on the adjusting shaft 6, and the first bevel gear 7 is slidably connected to the adjusting shaft 6. A second bevel gear 9 is fixedly installed at one end of the second bidirectional threaded rod 8 extending to the outer side of the ear plate. The first bevel gear 7 and the second bevel gear 9 are meshed together. Guide rails are provided on both sides of the adjusting shaft 6 along the length direction. A groove is opened on the inner wall of the first bevel gear 7, and the groove is engaged with the guide rail. The first bevel gear 7 and the second bevel gear 9 are also connected via an anti-detachment bracket 10. The anti-detachment bracket 10 has a right-angle structure. One side of the anti-detachment bracket 10 is sleeved on the second bidirectional threaded rod 8 and rotatably connected to the second bevel gear 9. The other side of the anti-detachment bracket 10 is sleeved on the adjusting shaft 6 and rotatably connected to the first bevel gear 7. When the positioning range needs to be adjusted according to the specifications of electronic components, the first bidirectional threaded rod 4, which is installed inside the assembly platform 1 and connected by a sprocket mechanism 5, is manually rotated. This causes the first bidirectional threaded rod 4 to drive the threaded adjusting plate 3 to move in opposite directions in the adjusting guide groove 2. During the movement of the adjusting plate 3, the second bidirectional threaded rod 8 inside it drives the first bevel gear 7 and the second bevel gear 9 to move through the anti-disengagement bracket 10, so that the first bevel gear 7 and the second bevel gear 9 are always in a meshing state. Furthermore, the adjusting shaft 6, which is installed behind the top surface of the assembly platform 1, is manually rotated. This causes the first bevel gear 7, which is connected to the outer wall by a protrusion, to rotate. The first bevel gear 7 then drives the meshing second bevel gear 9 and the second bidirectional threaded rod 8 to rotate inside the adjusting plate 3. This allows the second bidirectional threaded rod 8 to drive the positioning locking seats 11, which are threaded on both the front and rear sides, to move in opposite directions in the front and rear directions to accommodate the positioning of electronic components of different specifications.

[0041] In this embodiment, to ensure that the positioning locking seat 11 limits the electronic components, a pressing lifting plate 12 is provided on the side of the positioning locking seat 11 facing the center of the adjusting guide groove 2. The pressing lifting plate 12 is connected to the bottom of the positioning locking seat 11 through a return spring 13. The top of the positioning locking seat 11 has two vertical mounting slots, and each mounting slot is provided with a flip positioning rod 14. The flip positioning rod 14 is rotatably connected to the mounting slot so that when the flip positioning rod 14 is rotated to a horizontal state, it fixes the electronic components on the mounting lifting plate 12. A traction spring 15 is provided on the side of the flip positioning rod 14 facing the pressing lifting plate 12. One end of the traction spring 15 is connected to the flip positioning rod 14, and the other end of the traction spring 15 is connected to the bottom of the mounting slot. The flip positioning rod 14 has upright plates on both sides, and each upright plate has a sliding block 16 for restricting the rotation of the flip positioning rod 14. The sliding block 16 is slidably connected to the upright plate. A sliding spring 17 is provided at the tail of the sliding block 16. One end of the sliding spring 17 is connected to the tail of the sliding block 16, and the other end is connected to the side wall of the mounting groove. The sliding blocks 16 on both sides of one flip positioning rod 14 are connected by a traction rope 18, and the middle of the traction rope 18 is connected to the pressing lifting plate 12. The end of the traction rope 18 is connected to the sliding block 16, and the traction rope 18 passes through the sliding spring 17 and then connects to the pressing lifting plate 12. In this embodiment, a fixing button further restricts the direction of the traction rope 18, causing the traction rope 18 to be arranged in a clasping manner on the outside of the two sliding blocks 16. When it is necessary to limit the electronic component, first place the four corners of the electronic component on the pressing lifting plate 12 inside the positioning locking seat 11. Then, manually press the electronic component to make it move the pressing lifting plate 12 below downwards, and tighten the fixedly connected traction rope 18. The traction rope 18 then drives the upper fixedly connected abutment slider 16 to slide outwards inside the positioning locking seat 11. When the inner end of the abutment slider 16 no longer limits the flip positioning rod 14, the contraction of the traction spring 15 drives the flip positioning rod 14 to flip inwards, thereby making it abut against the four corners of the electronic component for locking and limiting, preventing the electronic component from shifting during assembly.
