Technical Field

[0001] This utility model relates to the field of watch component processing technology, and in particular to a dispensing device for watch surfaces. Background Technology

[0002] In the watchmaking industry, especially in the production of high-end smartwatches and precision mechanical watches, the surface epoxy coating process is a crucial step. Epoxy coating not only provides protection for the watch surface but also enhances its aesthetics and durability.

[0003] However, traditional epoxy resin application processes mostly rely on manual operation. This requires manual handling of the resin tube and applying resin one by one around the surface. Prolonged operation can easily cause hand soreness and discomfort, making it difficult to control the accuracy and efficiency of the resin application. Furthermore, if the resin is not properly controlled and overflows onto the surface, it can cause contamination and other problems, making it difficult to meet the high-quality and high-efficiency requirements of the modern watchmaking industry.

[0004] To address the aforementioned issues, this invention proposes an improved dispensing device for watch surfaces. The aim is to further enhance the precision and efficiency of dispensing by optimizing the mechanical structure and control system, while simultaneously reducing the difficulty of cleaning and maintaining the device, and improving operational flexibility and convenience. Utility Model Content

[0005] To overcome the shortcomings of existing watch face dispensing processes, such as low efficiency, insufficient precision, and susceptibility to contamination, the technical problem is to provide a dispensing device for watch faces that is easy to control flexibly and precisely.

[0006] The technical solution is as follows: A dispensing device for watch faces includes a processing table, a turntable, and a driving device. The turntable is rotatably connected to the top center of the processing table. Positioning grooves for placing the face are evenly spaced along the circumference of the turntable. A driving device for intermittently rotating the turntable is provided at the bottom of the processing table. The device also includes an adjustment component and a top ejector. An adjustment component for rotating and dispensing glue onto a glue tube is provided on the processing table. The adjustment component includes a connecting column, a fixing seat, a fixing ring, a clamp, and a handwheel. An upwardly extending connecting column is provided at the bottom center of the processing table. A fixing seat is connected to the top of the connecting column. A fixing ring is connected to the end of the fixing seat. A clamp for fixing the glue tube is slidably fitted on the fixing ring. A handwheel is rotatably connected to the fixing seat, and the lower end of the handwheel is connected to the clamp. A top ejector for automatically ejecting the face upwards is provided at the bottom of the processing table.

[0007] As a further improvement to the above technical solution, the top material component includes a cylinder, a connecting frame, and an infrared sensor. The cylinder is provided at the lower part of the processing table, and the end of the telescopic rod of the cylinder is connected to a top block. The top block can extend upwards out of the positioning groove to lift the surface upwards. The connecting frame is provided on the top right side of the processing table, and an infrared sensor for automatically identifying the sensing surface is provided on the connecting frame. The infrared sensor is located directly above the positioning groove during its stationary period, and the infrared sensor is electrically connected to the cylinder.

[0008] As a further improvement to the above technical solution, the positioning groove is provided with a liquid guiding structure for automatically draining and exporting residual overflowing colloid.

[0009] As a further improvement to the above technical solution, the liquid guiding structure is mainly composed of through holes and inclined grooves. A through hole is provided in the middle of the positioning groove, and inclined grooves connected to the through hole are provided at intervals along the circumference at the bottom and sidewalls of the positioning groove.

[0010] As a further improvement to the above technical solution, the driving device includes a gear ring, a drive motor, a control button, and a gear. The gear ring is sleeved on the outer side of the bottom of the turntable. The drive motor is provided on the lower right side of the processing table. The output shaft of the drive motor is connected to a gear, and the gear meshes with the gear ring. The control button is provided on the top right front side of the processing table, and the control button is electrically connected to the drive motor.

[0011] As a further improvement to the above technical solution, a feeding structure is also included, which includes a feeding trough and a retaining ring. The feeding trough is connected to the top left rear side of the processing table, and a retaining ring is connected to one end of the feeding trough near the turntable. The retaining ring is also located directly above the positioning groove during its stationary period.

[0012] This utility model has the following advantages: 1. The position and angle of the glue tube can be flexibly adjusted by the adjustment component to ensure that the glue nozzle of the glue tube can accurately and evenly drip glue around the watch surface, thereby improving the accuracy and uniformity of glue dripping on the surface; 2. The ejector component allows the watch surface after glue dripping to be automatically ejected upwards, facilitating subsequent operations and further improving the degree of automation; 3.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0023] Example 1: This utility model provides a dispensing device for watch faces, see reference. Figures 1 to 6As shown, the assembly includes a processing table 1, a turntable 6, a drive unit, an adjustment component, and a top material component. The turntable 6 is rotatably connected to the top center of the processing table 1. Positioning grooves 60 for placing surface a are evenly spaced along the circumference of the turntable 6. Inside each positioning groove 60 is a liquid-guiding structure for automatically draining any residual or overflowing adhesive. This liquid-guiding structure mainly consists of through holes 62 and inclined grooves 61. A through hole 62 is provided in the center of the positioning groove 60, and inclined grooves 61 connected to the through hole 62 are spaced along the circumference of the bottom and sidewalls of the positioning groove 60, facilitating the automatic discharge of residual or overflowing adhesive during the dispensing process and effectively preventing contamination of surface a. A drive unit is located at the bottom of the processing table 1, which drives the turntable 6 to rotate intermittently, allowing the positioning grooves 60 on the turntable 6 to... Each time, it can rotate and move one interval position accordingly; the processing table 1 is equipped with an adjustment component, which includes a connecting column 2, a fixed seat 3, a fixed ring 30, a ferrule 4, and a handwheel 5. The bottom center of the processing table 1 is provided with an upwardly extending connecting column 2, the top of the connecting column 2 is connected to the fixed seat 3, the end of the fixed seat 3 is connected to the fixed ring 30, and the ferrule 4 for fixing the glue tube b is slidably sleeved on the fixed ring 30. The fixed seat 3 is rotatably connected to the handwheel 5, and the lower end of the handwheel 5 is connected to the ferrule 4. By rotating the handwheel 5, it is easy to flexibly and conveniently control the glue tube b to rotate circumferentially along the surface a, which is conducive to uniform glue dripping on the surface a, and can effectively alleviate the discomfort of the hand due to long-term operation. The lower part of the processing table 1 is provided with a material ejector for automatically pushing the surface a upward.

[0024] For further details, please refer to [link / reference]. Figures 1 to 3 As shown, the driving device includes a gear ring 7, a drive motor 8, a control button 80, and a gear 9. The gear ring 7 is sleeved on the outer side of the bottom of the turntable 6. The drive motor 8 is located on the lower right side of the processing table 1. The output shaft of the drive motor 8 is connected to the gear 9, and the gear 9 meshes with the gear ring 7. The number of teeth of the gear ring 7 is 6 times the number of teeth of the gear 9, so that the gear 9 can drive the gear ring 7 and the turntable 6 on it to rotate 60 degrees every time it rotates. This allows the corresponding positioning groove 60 to rotate one interval position, which is beneficial for precise and continuous glue application to surface a. The control button 80 is located on the top right front side of the processing table 1, and the control button 80 is electrically connected to the drive motor 8.

[0025] For further details, please refer to [link / reference]. Figures 1 to 3As shown, the top material component includes a cylinder 10, a connecting frame 11, and an infrared sensor 12. The cylinder 10 is located at the lower part of the processing table 1, and a top block is connected to the end of the telescopic rod of the cylinder 10. The top block can extend upward into the positioning groove 60 to lift the surface a upward. The connecting frame 11 is located on the top right side of the processing table 1. An infrared sensor 12 for automatically identifying and sensing the surface a is installed on the connecting frame 11. The infrared sensor 12 is located directly above the positioning groove 60 during its stationary cycle. The infrared sensor 12 is electrically connected to the cylinder 10. When the surface a, after the glue has been applied, rotates and moves to a position directly below the infrared sensor 12, the infrared sensor 12 can automatically sense the presence of the surface a and send a signal to the controller so that the controller can control the telescopic rod of the cylinder 10 to extend, thereby automatically lifting the surface a, after the glue has been applied, upward.

[0026] During the glue application process, the watch face a is first precisely placed in the positioning groove 60 on the turntable 6, ensuring that face a is stable and does not shift during the glue application. Then, the glue cartridge b is securely fixed in the retaining sleeve 4 of the adjusting component. By carefully rotating the handwheel 5, the position of the retaining sleeve 4 and the glue cartridge b it supports can be flexibly adjusted, so that the glue nozzle of the glue cartridge b can accurately and evenly apply glue circumferentially along the positioning groove 60 of the watch face a. The drive device is activated, and the gear 9 drives the gear ring 7 and the turntable 6 to rotate intermittently, moving the watch face a one by one to the preset glue application position. At this time, the operator can precisely control the glue application operation by rotating the glue cartridge b in the adjusting component and using the fine-tuning function of the handwheel 5, ensuring that the glue is evenly and accurately dripped onto the watch face a. This helps improve the precision of the glue application on face a. Accuracy and efficiency: After the glue application process on watch face a is completed, the turntable 6 continues its intermittent rotation, moving the glued surface a directly below the infrared sensor 12. The infrared sensor 12, with its highly sensitive recognition capability, can quickly detect the presence of watch face a and immediately trigger the cylinder 10. The extension rod of the cylinder 10 then extends upwards, and its top block precisely pushes watch face a out of the positioning groove 60, greatly facilitating subsequent material handling. During the entire glue application process, if any glue residue or overflow occurs, the excess glue will flow smoothly along the carefully designed inclined groove 61 at the bottom of the positioning groove 60 into the through hole 62 and ultimately be discharged outside the positioning groove 60, effectively preventing glue contamination of the positioning groove 60 and avoiding any adverse effects on subsequent operations. In summary, this series of meticulous designs and operating procedures together constitute a highly efficient, precise, and easy-to-maintain glue application process for watch face a.

[0027] Example 2: Based on Example 1, refer to... Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, it also includes a feeding structure, which includes a feeding groove 13 and a retaining ring 14. The feeding groove 13 is connected to the top left rear side of the processing table 1. The feeding groove 13 facilitates the orderly arrangement of surfaces a one by one, which helps to improve the feeding efficiency. The end of the feeding groove 13 near the turntable 6 is connected to the retaining ring 14, and the retaining ring 14 is also located directly above the positioning groove 60 during its stationary period. The retaining ring 14 can play a precise positioning and guiding role when surface a falls into the positioning groove 60.

[0028] In addition, to further improve the ease of operation, a feeding structure has been specially designed. The operator only needs to place the watch face a in the feeding groove 13. As the turntable 6 continues to rotate, the watch face a will be cleverly guided by the retaining ring 14 to the stationary period position of the positioning groove 60, which is fully prepared for the subsequent dispensing operation.

[0029] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
