[0021] During use, the product to be glued is placed on the carrier block, and the drive motor automatically starts to rotate the product. Through the cooperation of the fixed dispensing needle and the rotating product carrier block, the product is dispensed in a ring-shaped line.

[0022] The aforementioned bracket 11 further includes a vertical portion connected to the upper surface of the second support plate 6 and a horizontal portion extending at one end above the first support plate 5.

[0023] The aforementioned connecting seat 15 is installed on the horizontal part of the bracket 11.

[0024] The aforementioned motor 7 is mounted on one side of the supporting plate 2 via a base 72.

[0025] One end of each of the aforementioned first support plate 5 and second support plate 6, which extend in opposite directions, is connected to the support plate 2.

[0026] The upper surface of the first support plate 5 is higher than the upper surface of the second support plate 6.

[0027] Example 2: A high-precision sleeve dispensing fixture includes: a base plate 1, a support plate 2 vertically mounted on the upper surface of the base plate 1, a glue tube 3, and a dispensing needle 4 mounted on the glue tube 3. A first support plate 5 and a second support plate 6 extending horizontally are respectively mounted on both sides of the support plate 2. The glue tube 3 is mounted on the second support plate 6. A motor 7 is mounted on the upper surface of the base plate 1, below the first support plate 5. A rotating column 8 is connected to the output shaft 71 of the motor 7. The upper end of the rotating column 8, whose lower end is connected to the output shaft 71 of the motor 7, passes through a through hole 51 opened in the first support plate 5 and rotates with the inner wall of the through hole 51. A carrier block 9 is provided on the upper end face of the rotating column 8, which is higher than the upper surface of the first support plate 5. A limiting pin 10 is provided in the center of the carrier block 9. A bracket 11 is mounted on the upper surface of the second support plate 6. The tube 3 is mounted on the bracket 11 via a connecting seat 15, such that the end of the dispensing needle 4 opposite to the tube 3 is located above the carrier block 9 and outside the limiting pin 10. The connecting seat 15 is provided with a first connecting hole 161 and a second connecting hole 162 spaced apart. The bracket 11 is provided with a first mounting hole 171 and a second mounting hole 172 corresponding to the first connecting hole 161 and the second connecting hole 162.

The strip-shaped second mounting hole 172 extends along an arc with the pin 12 as the center.

[0028] For different models of products to be processed, the distance and angle between the dispensing needle and the carrier can be adjusted by rotating the connector between the dispensing tube and the dispensing needle, so that the distance and angle between the product placed on the carrier and the dispensing needle can reach the optimal level.

[0029] The aforementioned bracket 11 further includes a vertical portion connected to the upper surface of the second support plate 6 and a horizontal portion extending at one end above the first support plate 5.

[0030] The aforementioned connecting seat 15 is installed on the horizontal part of the bracket 11.

[0031] The upper surface of the aforementioned limiting pin 10 is set as a spherical surface.

[0032] One end of each of the aforementioned first support plate 5 and second support plate 6, which extend in opposite directions, is connected to the support plate 2.

[0033] The upper surface of the first support plate 5 is higher than the upper surface of the second support plate 6.

[0034] The working principle is as follows: Before use, for different models of products to be processed, the distance and angle between the dispensing needle and the carrier need to be adjusted so that the distance and angle between the product placed on the carrier and the dispensing needle are optimal.

[0035] At this point, loosen the bolts connecting the second connecting hole and the second mounting hole, and rotate the connector seat with the rubber tube and dispensing needle installed around the pin connecting the first connecting hole and the first mounting hole until it reaches the appropriate position. During this process, the second connecting hole on the connector seat always moves within the strip-shaped second mounting hole. Finally, tighten the bolts to fix the connection between the connector seat and the bracket.

[0036] When in use, the ring-shaped product is loaded onto the carrier block and fitted onto the outside of the limit pin to achieve precise positioning of the product.

[0037] Simultaneously, the drive motor rotates once, and the dispensing needle on the hose performs one dispensing operation. The hose, dispensing head, and the glue supply components and dispensing control components that work with the hose are all within the scope of existing technology and will not be described in detail here.

[0038] By continuously dispensing glue through the dispensing needle, and in conjunction with the rotation of the rotating column that drives the product on the carrier block to rotate one revolution along with the output shaft of the motor, linear ring-shaped glue is dispensed onto the product. This ensures uniform and stable glue dispensing volume, improving dispensing efficiency and quality.

[0039] When using the aforementioned high-precision sleeve dispensing fixture, it achieves automated dispensing while simultaneously enabling circular dispensing of the product through the cooperation of a fixed dispensing needle and a rotating product carrier. This ensures uniform and stable dispensing volume, improving dispensing efficiency and quality. Furthermore, by rotating and adjusting the connecting seat, multi-dimensional adjustment of the relative position between the dispensing needle and the carrier can be achieved, ensuring that the distance and angle between the dispensing needle and the product are optimal during the dispensing process. This further enhances dispensing quality and improves the stability and ease of rotating the connecting seat.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
