Description

Technical Field

[0001] This invention relates to the field of adhesive coating technology for electronic components, specifically a high-precision positioning fixture for adhesive coating of electronic components. Background Technology

[0002] Adhesive coating is a crucial step in electronic component manufacturing. It encompasses various processes, including applying conductive adhesive, thermally conductive adhesive, fixing adhesive, and insulating / protective adhesive. Different applications require different coating thicknesses and coverage areas. Current technology typically uses adhesive coating machines. Before coating, the electronic components need to be positioned and fixed before applying the adhesive. While existing positioning fixtures are generally simple, specialized, and convenient, thus meeting current production needs to some extent, they still have the following drawbacks in practical use: 1. The existing positioning fixtures for applying adhesive to electronic components have limited adjustable directions for the clamping position, and can generally only be adjusted in one direction at a time. For some larger electronic components, it is necessary to rotate them at a certain angle to apply adhesive, and the existing technology cannot achieve better multi-angle synchronous and rapid positioning. 2. Existing positioning fixtures for applying adhesive to electronic components can only position and clamp a relatively small number of parts at a time, and the loading and unloading speed is slow. They cannot achieve rapid positioning of parts before applying adhesive, and their positioning and clamping efficiency needs to be further improved. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 10The present invention provides a technical solution: a high-precision positioning fixture for coating electronic components, comprising a rotating support mechanism and a positioning clamping mechanism provided at the upper end of the rotating support mechanism. The rotating support mechanism includes a support base 1, an intermediate rotating seat 2 at the upper end of the support base 1, and a top support base 3 at the upper end of the intermediate rotating seat 2. An angle adjustment component 4 is connected between the intermediate rotating seat 2 and the top support base 3. The positioning clamping mechanism includes positioning clamping components 5, which are evenly distributed and slidably mounted on the upper end of the top support base 3.

[0019] Furthermore, the support base 1 includes a fixed support plate I 101, and side support plates 102 are symmetrically arranged on the left and right sides of the fixed support plate I 101. A rotating support seat 103 is fixedly arranged in the middle of the lower end face of the fixed support plate I 101, and a rotating groove I 104 is opened in the middle of the rotating support seat 103. The lower end of the intermediate rotating seat 2 is fitted with the rotating groove I 104. Here, the rotating groove I 104 plays a rotating support role relative to the intermediate rotating seat 2.

[0020] Furthermore, the intermediate rotating seat 2 includes a rotating support plate II 201, and a rotating shaft 202 is vertically fixedly connected at the middle position of the lower end of the rotating support plate II 201. The rotating shaft 202 is fitted with the rotating groove I 104 through a bearing. A cover 105 is fastened to the bottom of the rotating shaft 202 and at the lower port of the rotating groove I 104. Here, the cover 105 plays a protective role relative to the rotating groove I 104. During operation, the rotating shaft 202 can rotate within the rotating groove I 104.

[0021] Furthermore, a gear ring fixing ring 203 is provided circumferentially at the lower end of the rotating support plate II 201 and on the outer side of the rotating shaft 202. An internal gear ring 204 is fixedly installed on the inner side of the gear ring fixing ring 203. A drive motor I 205 is fixedly installed on the inner side of the internal gear ring 204 and on the lower end face of the fixed support plate I101. A drive gear 206 is fixedly sleeved on the upper end of the rotating support plate II 201 and on the main shaft of the drive motor I 205. The drive gear 206 meshes with the internal gear ring 204. When the drive motor I 205 is started, it drives the drive gear 206 to mesh with the internal gear ring 204, which can drive the rotating support plate II 201 to rotate around the center of the rotating groove I 104, thereby controlling the rotation angle of the top support base 3 and the angle adjustment component 4 at the upper end of the intermediate rotating seat 2.

[0022] Furthermore, the top support base 3 includes a top support plate 301, and a positioning adjustment seat 302 evenly distributed on the upper end of the top support plate 301. The upper end of the positioning adjustment seat 302 is provided with a positioning groove 303. The lower end of the positioning clamping assembly 5 is slidably engaged with the positioning groove 303.

The upper and lower ends of the lifting cylinder II 406 are hinged to the right upper hinge seats 404 and the left lower hinge seats 405, respectively. By controlling the lifting cylinder I... The extension and retraction of 403 and lifting cylinder II 406 can control the lifting height of the top support base 3 relative to the middle rotating seat 2, and can also control the tilt angle of the upper end of the top support base 3 relative to the middle rotating seat 2.

[0024] Furthermore, the positioning and clamping assembly 5 includes a positioning support plate 501, and a positioning platform 505 is fixedly embedded on the upper end of the positioning support plate 501. A positioning slider 502 is fixedly provided on the lower end of the positioning support plate 501. The positioning slider 502 is slidably engaged with the positioning groove 303. The positioning platform 505 can be made of an elastic material to reduce wear between electronic components and tooling.

[0025] Furthermore, a side positioning adjustment plate I 503 is vertically fixedly connected to one side of the lower end of the positioning support plate 501, and a positioning adjustment screw 504 is screwed onto the side of the side positioning adjustment plate I 503. The inner end face of the positioning adjustment screw 504 abuts against the side of the positioning adjustment seat 302. By adjusting the tightness of the positioning adjustment screw 504, the relative sliding state between the positioning support plate 501 and the positioning groove 303 can be controlled.

[0026] Furthermore, side positioning adjustment plates II 506 are symmetrically arranged on the four outer surfaces of the positioning support plate 501, and a limiting plate 507 is provided on the inner side of the side positioning adjustment plate II 506. An elastic top plate 508 is attached to the inner surface of the limiting plate 507. Here, the elastic top plate 508 can be made of elastic material to reduce wear between it and the electronic components. Guide posts 509 are vertically fixedly connected to the left and right sides of the limiting plate 507. A rotating connecting seat 511 with a sleeve structure is fixedly installed at the middle position of the outer surface of the limiting plate 507. An adjusting screw I 510 is screwed into the middle of the side positioning adjustment plate II 506. The shaft end of the adjusting screw I 510 is fitted with the middle of the rotating connecting seat 511 through a bearing. During operation, the relative distance between the limiting plate 507 and the side positioning adjustment plate II 506 can be controlled by rotating the adjusting screw I 510, thereby controlling the positioning size of the electronic components on the upper end of the positioning stage 505.

[0027] Furthermore, an automatic adjustment seat 513 is fixedly provided on the outer sides of the two adjacent edges of the positioning support plate 501 and at the center of the outer side of the side positioning adjustment plate II 506. An adjustment screw II 514 is sleeved in the middle of the automatic adjustment seat 513. The adjustment screw II 514 is screwed to the adjustment screw I 510. A drive motor II 514 is fixedly installed on the upper end of the automatic adjustment seat 513. The main shaft of the drive motor II 514 is fixedly connected to the shaft end of the adjustment screw II 514. When the drive motor II 514 is started, the adjustment screw II 514 and the adjustment screw I 510 are screwed together and driven, thereby automatically controlling the positioning dimension of the limit plate 507 relative to the workpiece.

[0028] Working Principle: During operation, the number of positioning and clamping components 5 on the upper end of the top support base 3 is controlled according to the size of the electronic component. Based on the outer dimensions of the electronic component, adjusting screw I 510 is adjusted to pre-set the fixed position of the limiting plate 507 on the upper end of the positioning support plate 501. During operation, the electronic component is placed on the positioning stage 505, and drive motor II 514 is started. This controls the screw connection between adjusting screw II 514 and adjusting screw I 510, thereby controlling the limiting plates 507 on the other two sides of the electronic component to push towards the sides of the electronic component. The elastic top plate 508 then clamps and fixes the other two sides of the electronic component. This fixing method is simple and fast. Furthermore, through automatic control by drive motor II 514, the positioning and clamping degree around the electronic component can be controlled, making the force more stable and preventing damage to the workpiece. During operation, when the adhesive application angle needs to be adjusted, drive motor I 205, lifting cylinder I 403, and lifting cylinder II can be started simultaneously. 406. The angle between the workpiece at the upper end of the positioning stage 505 and the glue applicator head is controlled so that the glue applicator head can more easily enter the glue applicator area to perform the glue applicator action. This invention can realize multi-angle adjustment of electronic components during the glue applicator process.
