Description

Technical Field

[0001] This utility model belongs to the field of electronic component processing technology, and in particular relates to a positioning fixture for coating electronic components. Background Technology

[0002] In the production of electronic components, adhesive coating is a common and important process. The quality of the adhesive coating directly affects the performance and lifespan of the electronic components. However, existing positioning fixtures for adhesive coating of electronic components still have some problems. For example, the utility model patent with publication number CN218282389U includes a support base, the top of which is mounted with a placement plate via a rotating assembly. A mounting bracket is fixedly connected to the top surface of the placement plate, and a positioning rod is rotatably mounted on the mounting bracket. This utility model lacks a preliminary positioning function, directly placing the device on the placement plate for operation. This may lead to inaccurate fixture positioning, requiring repeated calibration and affecting work efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a positioning fixture for coating electronic components. By setting a positioning plate, specifically by rotating the handle, the lead screw rotates inside the slide groove. Since the lead screw has two opposite threads on its outer surface, it drives two sliders to move closer or further apart, thereby adjusting the distance between the two positioning plates. This adapts to the rapid positioning of components of different specifications and solves the problem that existing positioning fixtures for coating electronic components do not have a preliminary positioning function, which may lead to inaccurate positioning and affect work efficiency.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a positioning fixture for coating electronic components, comprising an operating table and fixture assemblies. A placement platform is fixedly connected to the center of the top of the operating table. Two fixture assemblies are provided, one on the front and one on the back of the placement platform on the top of the operating table. Each fixture assembly includes a clamping block, and an electric push rod is provided on the side of the clamping block away from the placement platform on the top of the operating table. Two positioning plates are slidably connected to the top of the operating table. A sliding groove is provided on the top of the operating table, and a slider is slidably connected to the inner wall of the groove. The top of the slider is fixedly connected to the bottom of the positioning plate. A lead screw is rotatably connected inside the groove, and the threads on the outer surface of the lead screw are arranged in two opposite directions. The outer surface of the lead screw is threaded to the inner surface of the slider. A rotating handle is rotatably connected to the left side of the operating table, and the right side of the rotating handle is fixedly connected to the left side of the lead screw. Through the sliding groove, the slider, and the bidirectional threaded lead screw, combined with the operation of the rotating handle, synchronous and symmetrical movement of the positioning plates is achieved, enabling rapid positioning of electronic components of different sizes and improving work efficiency.

[0006] Furthermore, four limiting guide rails are fixedly connected to the top of the operating table. The outer surfaces of two of the limiting guide rails are slidably connected to the inside of the positioning plate. By utilizing the sliding connection between the four limiting guide rails and the lower positioning plate, the positioning plate is ensured to maintain linear motion and stability during movement, preventing deviation or shaking and improving positioning accuracy.

[0007] Furthermore, the top of the positioning plate contacts the upper positioning plate, and a second lead screw is rotatably connected inside the positioning plate. The outer surface of the second lead screw is threadedly connected to the inside of the upper positioning plate. A first bevel gear is fixedly connected to the bottom of the second lead screw. A second bevel gear is rotatably connected inside the positioning plate, and the outer surface of the second bevel gear meshes with the outer surface of the first bevel gear. A first knob is rotatably connected to the side of the positioning plate near the second bevel gear. The side of the first knob near the second bevel gear is fixedly connected to the side of the second bevel gear away from the first bevel gear. Through the design of the second lead screw, the bevel gear transmission, and the first knob, the height of the upper positioning plate can be easily and finely adjusted to adapt to electronic components of different heights, improving flexibility while simplifying operation steps and improving work efficiency.

[0008] Furthermore, two limiting rods are fixedly connected to the top of the positioning plate. The outer surface of the limiting rod is slidably connected to the inside of the upper positioning plate. The sliding connection between the limiting rod and the upper positioning plate constrains the movement trajectory of the upper positioning plate, prevents it from tilting or rotating in the vertical direction, and improves the stability of the upper positioning plate.

[0009] Furthermore, the clamping assembly includes a clamping block, a support plate fixedly connected to the back of the clamping block located on the rear side, an upper clamping block slidably connected to the front of the support plate, a lead screw three rotatably connected to the top of the clamping block and the inner wall of the support plate, the outer surface of the lead screw three being threadedly connected to the inside of the upper clamping block, and a knob two rotatably connected to the top of the support plate, the bottom of the knob two being fixedly connected to the top of the lead screw three. The lead screw three and the knob two are used to control the lifting and lowering of the upper clamping block, adjusting the height of the upper clamping block to accommodate electronic components of different heights, further improving flexibility.

[0010] Furthermore, two limiting rods are fixedly connected to the top of the clamping block and the inner wall of the support plate. The outer surfaces of the two limiting rods are slidably connected to the inside of the upper clamping block. The upper clamping block is guided to slide by the two limiting rods, ensuring that the upper clamping block maintains vertical movement during clamping, reducing lateral swaying and improving the reliability of clamping.

[0011] Furthermore, a connecting plate is fixedly connected to the output end of the electric push rod located on the front side. Two damping rods are fixedly connected to the back of the connecting plate. Springs are sleeved on the outer surface of the damping rods. The back of the damping rods is fixedly connected to the front of the support plate. The damping rods, springs and connecting plate are set at the output end of the electric push rod to form a buffer system, which can absorb the impact force during clamping, prevent electronic components from being damaged due to sudden force, and extend the service life of the equipment.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model sets up a positioning plate, specifically by rotating the rotary handle to drive the lead screw to rotate inside the slide groove. Since the lead screw has two opposite threads on its outer surface, it drives the two sliders to move closer or further away from each other at the same time, thereby adjusting the distance between the two positioning plates. This adapts to the rapid positioning of electronic components of different specifications and improves work efficiency.

[0014] 2. This utility model, by setting an upper positioning plate and an upper clamping block, specifically, by rotating knob one, the lead screw two is driven to rotate inside the positioning plate through bevel gear two and bevel gear one, thereby adjusting the height of the upper positioning plate. Rotating knob two drives the lead screw three to rotate at the top of the clamping block, adjusting the height of the upper clamping block. This enables better positioning and clamping functions for electronic components of different heights, improving the adaptability of the device.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-5 As shown, this utility model is a positioning fixture for coating electronic components, including an operating table 1 and a fixture assembly 2. A placement platform is fixedly connected to the center of the top of the operating table 1. Two fixture assemblies 2 are provided, one on the front and one on the back of the placement platform on the top of the operating table 1. Each fixture assembly 2 includes a clamping block 21, with an electric push rod 22 on the side of the clamping block 21 away from the placement platform on the top of the operating table 1. Two positioning plates 11 are slidably connected to the top of the operating table 1. A sliding groove 111 is provided on the top of the operating table 1, and a slider 112 is slidably connected to the inner wall of the sliding groove 111. The top of the slider 112 is fixedly connected to the bottom of the positioning plate 11. The inside of the sliding groove 111 rotates... The system is connected to a lead screw 113, whose outer surface has two opposite threads. The outer surface of the lead screw 113 is threaded to the inner surface of the slider 112. A rotating handle 114 is rotatably connected to the left side of the operating table 1. The right side of the rotating handle 114 is fixedly connected to the left side of the lead screw 113. By setting a positioning plate 13, specifically by rotating the rotating handle 114, the lead screw 113 is driven to rotate inside the slide groove 111. Because the two opposite threads on the outer surface of the lead screw 113 are set, the two sliders 112 are driven to move closer or further away from each other at the same time, thereby adjusting the distance between the two positioning plates 11. This allows for the rapid positioning of different specifications of devices and improves work efficiency.

[0026] Four limit guide rails 115 are fixedly connected to the top of the control panel 1, and the outer surfaces of two limit guide rails 115 are slidably connected to the inside of the positioning plate 11.

[0027] The top of the positioning plate 11 contacts the upper positioning plate 12. A second lead screw 121 is rotatably connected inside the positioning plate 11. The outer surface of the second lead screw 121 is threadedly connected to the inside of the upper positioning plate 12. A first bevel gear 122 is fixedly connected to the bottom of the second lead screw 121. A second bevel gear 123 is rotatably connected inside the positioning plate 11. The outer surface of the second bevel gear 123 meshes with the outer surface of the first bevel gear 122. A first knob 124 is rotatably connected to the side of the positioning plate 11 near the second bevel gear 123. The side of the first knob 124 near the second bevel gear 123 is fixedly connected to the side of the second bevel gear 123 away from the first bevel gear 122.

[0028] Two limiting rods 125 are fixedly connected to the top of the positioning plate 11, and the outer surface of the limiting rods 125 is slidably connected to the inside of the upper positioning plate 12.

[0029] The clamping assembly 2 includes a clamping block 21. A support plate 211 is fixedly connected to the back of the clamping block 21. An upper clamping block 212 is slidably connected to the front of the support plate 211. A lead screw 213 is rotatably connected to the top of the clamping block 21 and the inner wall of the support plate 211. The outer surface of the lead screw 213 is threadedly connected to the inside of the upper clamping block 212. A knob 214 is rotatably connected to the top of the support plate 211. The bottom of the knob 214 is fixedly connected to the top of the lead screw 213. An upper positioning plate 12 and an upper clamping block 212 are provided. Specifically, rotating the knob 124 causes the lead screw 221 to rotate inside the positioning plate 11 through bevel gears 223 and 122, thereby adjusting the height of the upper positioning plate 12. Rotating the knob 214 causes the lead screw 213 to rotate on the top of the clamping block 21, adjusting the height of the upper clamping block 212. This provides good positioning and clamping functions for devices of different heights, improving the adaptability of the device.

[0030] Two limiting rods 215 are fixedly connected to the top of the clamping block 21 and the inner wall of the support plate 211. The outer surfaces of the two limiting rods 215 are slidably connected to the inside of the upper clamping block 212.

[0031] The output end of the electric actuator 22 located on the front is fixedly connected to a connecting plate 221. Two damping rods 222 are fixedly connected to the back of the connecting plate 221. Springs 223 are sleeved on the outer surface of the damping rods 222. The back of the damping rods 222 is fixedly connected to the front of the support plate 211.

[0032] A specific application of this embodiment is as follows: In use, firstly, adjust the distance between the two positioning plates 11 according to the size of the electronic components. Rotate the rotary handle 114 to drive the lead screw 113 to rotate inside the slide groove 111. Since the lead screw 113 has two opposite threads on its outer surface, it drives the two sliders 112 to move closer or further away from each other, thereby adjusting the distance between the two positioning plates 11. While the positioning plates 11 move, they slide on the outer surface of the limiting guide rail 115. The limiting guide rail 115 provides a stable movement trajectory for the positioning plates 11. Then, adjust the height of the upper positioning plate 12 and the upper clamping block 212 according to the height of the electronic components. Rotate the knob 124 to drive the lead screw 121 to rotate inside the positioning plate 11 through the bevel gear 123 and bevel gear 122, thereby making the upper positioning plate 121 rotate inside the positioning plate 11. 2. Move and adjust the height of the upper positioning plate 12. Rotate knob 214 to drive screw 3 213 to rotate on top of clamping block 21, causing the upper clamping block 212 to move. Adjust the height of the upper clamping block 212. While the upper positioning plate 12 and the upper clamping block 212 are moving, the upper positioning plate 12 slides on the outer surface of limit rod 125, and the upper clamping block 212 slides on the outer surface of limit rod 215. Limit rod 125 and limit rod 215 provide a stable movement trajectory for the movement of the upper positioning plate 12 and the upper clamping block 212. Then, place the electronic component on the top placement platform of the operating table 1 and simultaneously activate the two electric push rods 22 to clamp and fix it. When the clamping block 21 and the upper clamping block 212 come into contact with it, the damping rod 222 and the spring 223 contract to buffer the impact force and avoid excessive clamping force from damaging the surface of the electronic component.
