Description

Technical Field

[0001] This utility model relates to the field of watch manufacturing technology, and in particular to a watch manufacturing adhesive dispensing device. Background Technology

[0002] As a precision instrument worn daily, the water resistance of a watch is one of the important indicators of its quality. The adhesive application process is widely used in various waterproof structures of watches. By applying a specific waterproof adhesive, a tight sealing layer is formed to prevent water, moisture and dust from entering the watch and to ensure that the movement and other sensitive components are not corroded.

[0003] Currently, when applying adhesive to watches, dispensing machines or manual dispensing are commonly used. However, both methods have some unsatisfactory issues: when dispensing manually, due to human factors, the operator often finds it difficult to maintain a constant pressure, which leads to fluctuations in the amount of adhesive dispensed, resulting in inconsistent dispensing effects and affecting the quality of the final product. While dispensing machines improve work efficiency, new problems arise. The dispensing paths and angles required for different parts of a watch are diverse, while the angle of the dispensing tube is mostly fixed. This makes it impossible to accurately align the dispensing position, resulting in the adhesive often failing to cover the target area evenly and precisely, which undoubtedly reduces the quality and accuracy of the dispensing. The existing patent (publication number: CN222490757U) discloses a glue dispensing device for watch processing. This utility model can squeeze the glue liquid through the extrusion mechanism to make the glue output uniform and stable, thus ensuring the glue dispensing effect. The angle of the glue dispensing cylinder can be adjusted through the rotation mechanism, thereby accurately aligning the glue application position and improving the glue dispensing quality.

[0004] To address the aforementioned issues, existing patents offer solutions. However, the watch processing dispensing devices proposed in these patents have significant drawbacks in practical use. On one hand, the fluid colloid in the dispensing cylinder tends to drip automatically when not in operation, and the device lacks any colloid collection and processing structure. The dripping colloid not only contaminates the base plate, placement plate, and watch processing parts but also, due to its difficulty in cleaning after curing, affects subsequent processing accuracy and efficiency. On the other hand, although the patents mention that the dispensing cylinder is equipped with a dispensing valve to control the discharge of the colloid, it does not explicitly state that this valve has a precise flow rate adjustment function. Relying solely on the squeezing force of the extrusion mechanism is insufficient to achieve flow rate adaptation for different dispensing scenarios, and the sealing performance of the dispensing valve is not adequately guaranteed, easily leading to colloid dripping problems when not in operation. Furthermore, the lack of an emergency protection design for dripping colloid further reduces the practicality and cleanliness of the device, affecting the stability of the processing flow and the product qualification rate.

[0005] Therefore, a gluing device for watch manufacturing is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a watch processing dispensing device that can solve the obvious defects of the watch processing dispensing device proposed in the above-mentioned patent in actual use. On the one hand, the fluid colloid in the dispensing cylinder is prone to dripping automatically when not in operation, and the device does not have any colloid collection and treatment structure. The dripping colloid will not only contaminate the base plate, the placement plate and the watch processing parts, but will also affect the subsequent processing accuracy and efficiency due to the difficulty in cleaning after curing. On the other hand, although the patent mentions that the dispensing cylinder is equipped with a dispensing valve to control the discharge of the colloid, it does not clearly state that the valve has a precise flow adjustment function. It is difficult to achieve flow adaptation for different dispensing scenarios by relying solely on the squeezing force of the squeezing mechanism, and the sealing performance of the dispensing valve is not fully guaranteed, which can easily lead to the problem of colloid dripping when not in operation. At the same time, there is no emergency protection design for dripping colloid, which further reduces the practicality and cleanliness of the device and affects the stability of the processing flow and the quality of the product.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a watchmaking glue dispensing device, including a glue dispensing platform, a controller on the right side of the glue dispensing platform, a bracket welded to the rear side of the top of the glue dispensing platform, a groove on the front side of the bracket, a drive motor bolted to the right side of the bracket, a lead screw fixedly connected to the output end of the drive motor, a moving block threadedly connected to the surface of the lead screw, the moving block slidably connected inside the groove, a corner structure at the bottom of the moving block, a fixed sleeve welded to the front side of the corner structure, a glue dispensing cylinder inside the fixed sleeve, a glue extrusion structure at the top of the glue dispensing cylinder, a glue dispensing structure at the bottom of the glue dispensing cylinder, and a glue receiving structure at the bottom of the glue dispensing structure; The adhesive receiving structure includes an electric cylinder embedded inside the bracket. The telescopic end of the electric cylinder is fixedly connected to an adhesive receiving cylinder, which is located at the bottom of the adhesive dispensing structure. A cap is inserted into the bottom of the adhesive receiving cylinder.

[0008] Preferably, the dispensing structure includes a connecting pipe fixedly connected to the bottom of the dispensing cylinder, and a transfer cylinder is threadedly connected to the bottom of the connecting pipe.

[0009] Preferably, the transfer cylinder is equipped with a filter screen inside, and the bottom of the transfer cylinder is connected to a flow regulating valve, which is electrically connected to the automatic controller.

[0010] Preferably, the bottom of the flow regulating valve is connected to a dispensing head, and the bottom of the dispensing head is conical.

[0011] Preferably, the corner structure includes an electric telescopic rod embedded in the bottom of the moving block, a cavity box is fixedly connected to the bottom of the electric telescopic rod, a servo motor is bolted to the rear side of the cavity box, a shaft is rotatably connected inside the cavity box, and the rear side of the shaft is fixedly connected to the output end of the servo motor.

[0012] Preferably, a first electric push rod is bolted to both the top and bottom of the cavity box. A sleeve is fixedly connected to the telescopic end of the first electric push rod. The sleeve is located outside the shaft. A vertical rod is fixedly connected to the front side of the shaft. The front side of the vertical rod is welded to the rear side of the fixed sleeve.

[0013] Preferably, the extrusion structure includes a second electric push rod bolted to the top of the upright, and the telescopic end of the second electric push rod is fixedly connected to a fixed shaft.

[0014] Preferably, a piston is fixedly connected to the bottom of the fixed shaft, and the piston is slidably connected inside the dispensing cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up a dispensing cylinder, a dispensing structure, and a receiving structure. The dispensing structure at the bottom of the dispensing cylinder can accurately control the amount of adhesive flowing out, adapting to the needs of different dispensing scenarios and avoiding the situation where it is difficult to adjust the flow rate by relying solely on the extrusion mechanism. When the device is not in operation, the electric cylinder inside the bracket can drive the receiving cylinder to move to the bottom of the dispensing structure to catch any dripping adhesive, preventing contamination of the dispensing table and processing parts. The cap at the bottom of the receiving cylinder facilitates the subsequent cleaning of the collected adhesive, solving the problem of difficult cleaning of dripping adhesive and ensuring the cleanliness of the processing environment and the accuracy of subsequent processing. 2. This application incorporates a corner structure and an extrusion structure. The corner structure allows the dispensing cylinder to adjust its angle to accommodate the dispensing needs of different parts of the watch, while the extrusion structure applies stable pressure to the adhesive inside the cylinder. Combined with the dispensing structure, this ensures a more uniform flow of adhesive, reducing processing problems caused by unstable dispensing and further guaranteeing the stability of the processing flow and the product qualification rate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0019] Please see Figure 1-6 The present invention provides the following technical solution: A watchmaking dispensing device includes a dispensing platform 1, a controller 2 on the right side of the dispensing platform 1, a bracket 3 welded to the rear side of the top of the dispensing platform 1, a groove 4 on the front side of the bracket 3, a drive motor 5 bolted to the right side of the bracket 3, a lead screw 6 fixedly connected to the output end of the drive motor 5, a moving block 7 threadedly connected to the surface of the lead screw 6, the moving block 7 slidably connected inside the groove 4, a corner structure 8 at the bottom of the moving block 7, a fixed sleeve 9 welded to the front side of the corner structure 8, a dispensing cylinder 10 inside the fixed sleeve 9, a glue extrusion structure 11 at the top of the dispensing cylinder 10, a glue dispensing structure 12 at the bottom of the dispensing cylinder 10, and a glue receiving structure 13 at the bottom of the glue dispensing structure 12. The adhesive receiving structure 13 includes an electric cylinder 1301 embedded inside the bracket 3. The telescopic end of the electric cylinder 1301 is fixedly connected to an adhesive receiving tube 1302. The adhesive receiving tube 1302 is located at the bottom of the adhesive dispensing structure 12. A cap 1303 is inserted into the bottom of the adhesive receiving tube 1302.

[0020] In this embodiment: by setting up a dispensing platform 1, a controller 2, a bracket 3, a groove 4, a drive motor 5, a lead screw 6, a moving block 7, a corner structure 8, a fixed sleeve 9, a dispensing cylinder 10, an extrusion structure 11, a dispensing structure 12, and a receiving structure 13, the operator first places the watch to be processed on the dispensing platform 1, sets the dispensing parameters through the controller 2 on the right side of the dispensing platform 1, and then starts the drive motor 5 to start working, driving the lead screw 6 at the output end to rotate. Since the moving block 7 is threadedly connected to the lead screw 6 and slides in the groove 4 on the front side of the bracket 3, the rotation of the lead screw 6 will drive the moving block 7 to move left and right along the groove 4. Then, through the corner structure 8 at the bottom of the moving block 7, the fixed sleeve 9 and the dispensing cylinder 10 inside will be adjusted left and right synchronously to accurately align with the dispensing area of ​​the watch. Then, the corner structure 8 can flexibly adjust the angle of the dispensing cylinder 10 to adapt to the dispensing needs of different parts of the watch, ensuring accurate dispensing position. After that, the extrusion of glue from the top of the dispensing cylinder 10... When structure 11 is activated, it applies stable pressure to the colloid inside the cylinder, pushing the colloid to the bottom. At this time, the dispensing structure 12 at the bottom of the dispensing cylinder 10 will precisely control the amount of colloid flowing out according to the parameters set by the automatic controller 2, avoiding too much or too little dispensing, and meeting the needs of different dispensing scenarios. When the device completes the dispensing operation and is in a non-working state, the electric cylinder 1301 embedded in the bracket 3 will drive the receiving cylinder 1302 at the telescopic end to move directly below the dispensing structure 12 to catch any dripping colloid, preventing the colloid from contaminating the dispensing table 1 and the watch processing parts. The cap 1303 at the bottom of the receiving cylinder 1302 can be removed at any time, making it convenient to clean the collected colloid later, ensuring the cleanliness of the processing environment and the accuracy of subsequent processing. The whole process, through the coordinated cooperation of various structures, under the unified control of the automatic controller 2, achieves precise control of the dispensing position, angle, and flow rate, while solving the problem of colloid drip contamination, ensuring a stable and efficient processing flow.

[0021] Specifically, such as Figure 4 As shown, the dispensing structure 12 includes a connecting pipe 1201 fixedly connected to the bottom of the dispensing cylinder 10, and a transfer cylinder 1202 is threadedly connected to the bottom of the connecting pipe 1201.

[0022] Specifically, such as Figure 4 As shown, a filter screen 1203 is installed inside the transfer cylinder 1202, and a flow regulating valve 1204 is connected to the bottom of the transfer cylinder 1202. The flow regulating valve 1204 is electrically connected to the automatic controller 2.

[0023] Specifically, such as Figure 4 As shown, the bottom of the flow regulating valve 1204 is connected to a dispensing head 1205, and the bottom of the dispensing head 1205 is conical.

[0024] In this embodiment: By setting the dispensing structure 12, the connecting pipe 1201 is fixed to the bottom of the dispensing cylinder 10, providing a channel for the dispensing of the adhesive. The transfer cylinder 1202, which is threaded to the bottom of the connecting pipe 1201, is easy to disassemble, replace and clean. The filter screen 1203 inside the transfer cylinder 1202 can filter impurities in the adhesive, preventing impurities from clogging the subsequent channel and affecting the smoothness of dispensing. The flow regulating valve 1204 connected to the bottom of the transfer cylinder 1202 is electrically connected to the automatic controller 2. The operator can accurately set the flow parameters through the automatic controller 2 to control the dispensing speed and total amount of the adhesive, adapting to the dispensing needs of different watch parts. The conical dispensing head 1205 at the bottom of the flow regulating valve 1204 can concentrate the dispensing, further improving the accuracy of the dispensing position, ensuring that the adhesive evenly covers the target area, and avoiding processing defects caused by uneven or excessive dispensing.

[0025] Specifically, such as Figure 5 As shown, the corner structure 8 includes an electric telescopic rod 801 embedded in the bottom of the moving block 7. A cavity box 802 is fixedly connected to the bottom of the electric telescopic rod 801. A servo motor 803 is bolted to the rear side of the cavity box 802. A shaft 804 is rotatably connected inside the cavity box 802. The rear side of the shaft 804 is fixedly connected to the output end of the servo motor 803.

[0026] Specifically, such as Figure 5 As shown, the top and bottom of the cavity box 802 are both bolted with a first electric push rod 805. The telescopic end of the first electric push rod 805 is fixedly connected to a sleeve 806. The sleeve 806 is located outside the shaft 804. The front side of the shaft 804 is fixedly connected to a vertical rod 807. The front side of the vertical rod 807 is welded to the rear side of the fixed sleeve 9.

[0027] In this embodiment: by setting the corner structure 8, the electric telescopic rod 801 embedded in the bottom of the moving block 7 can be flexibly adjusted in length, driving the bottom cavity box 802 to move up and down, thereby adjusting the height of the dispensing cylinder 10 to adapt to the dispensing distance of watches of different sizes. After the servo motor 803 bolted to the rear of the cavity box 802 is started, it will drive the internal shaft 804 to rotate. The upright rod 807 fixed to the front of the shaft 804 will rotate synchronously. The front of the upright rod 807 is welded to the fixed sleeve 9, which will eventually drive the fixed sleeve 9 and the internal dispensing cylinder 10 to adjust the angle to meet the dispensing angle requirements of different parts of the watch. After the angle is adjusted to the correct position, the first electric push rod 805 at the top and bottom of the cavity box 802 will extend, driving the clamp 806 to clamp the outside of the shaft 804, fixing the shaft 804, preventing the shaft 804 from rotating during the dispensing process and causing the dispensing angle to shift, thus ensuring the stability and accuracy of the dispensing.

[0028] Specifically, such as Figure 6As shown, the extrusion structure 11 includes a second electric push rod 1101 bolted to the top of the upright 807, and a fixed shaft 1102 is fixedly connected to the telescopic end of the second electric push rod 1101.

[0029] Specifically, such as Figure 6 As shown, a piston 1103 is fixedly connected to the bottom of the fixed shaft 1102, and the piston 1103 is slidably connected inside the dispensing cylinder 10.

[0030] In this embodiment: by setting up the extrusion structure 11, the second electric push rod 1101 is bolted to the top of the upright 807 to provide a power source for extrusion. When dispensing is required, the telescopic end of the second electric push rod 1101 will push the fixed shaft 1102 downward. The piston 1103 at the bottom of the fixed shaft 1102 will slide downward inside the dispensing cylinder 10. The piston 1103 is in close contact with the inner wall of the dispensing cylinder 10. During the sliding process, it can apply stable and uniform pressure to the glue in the cylinder, pushing the glue to flow smoothly from the bottom of the dispensing cylinder 10 into the dispensing structure 12. With the help of the flow regulating valve 1204, precise dispensing is achieved, avoiding fluctuations in the dispensing volume due to unstable extrusion force, and ensuring the consistency of dispensing effect.

[0031] Working Principle: During the glue dispensing process on a watch, the operator first places the watch to be processed on the glue dispensing table 1. The operator then sets the dispensing flow rate, dispensing position, and other relevant parameters using the automatic controller 2 on the right side of the glue dispensing table 1. The entire device is then started, and the drive motor 5 on the right side of the bracket 3 begins to operate. The lead screw 6, fixedly connected to its output end, rotates accordingly. Since the moving block 7 is threadedly connected to the lead screw 6 and slidably connected inside the groove 4 on the front side of the bracket 3, the rotation of the lead screw 6 drives the moving block 7 to move smoothly left and right along the groove 4. The corner structure 8 at the bottom of the moving block 7 moves synchronously, thereby adjusting the left and right position of the internal glue dispensing cylinder 10 through the fixed sleeve 9, precisely aligning it with the area of ​​the watch requiring glue dispensing. Then, the corner structure... The electric telescopic rod 801 embedded in the bottom of the middle moving block 7 can flexibly adjust its length, driving the bottom cavity box 802 to move up and down, thereby adjusting the height of the dispensing cylinder 10 to adapt to the dispensing distance of different sized watches. Then, the servo motor 803 bolted to the rear of the cavity box 802 starts, driving the internal shaft 804 to rotate. The upright rod 807 fixedly connected to the front of the shaft 804 rotates synchronously. The fixed sleeve 9 welded to the front of the upright rod 807 then drives the dispensing cylinder 10 to adjust its angle to meet the dispensing angle requirements of different parts of the watch. After the angle is adjusted to the correct position, the first electric push rod 805 at the top and bottom of the cavity box 802 extends, driving the clamp 806 to clamp the outside of the shaft 804, fixing the shaft 804 and preventing over-dispensing. During the process, the angle deviates, and then the extrusion structure 11 at the top of the dispensing cylinder 10 starts to work. The telescopic end of the second electric push rod 1101, which is bolted to the top of the upright 807, pushes the fixed shaft 1102 downward. The piston 1103 at the bottom of the fixed shaft 1102 slides downward inside the dispensing cylinder 10. The piston 1103 is in close contact with the inner wall of the dispensing cylinder 10, applying stable and uniform pressure, pushing the glue in the cylinder to the bottom. The glue flows into the transfer cylinder 1202 through the connecting pipe 1201 at the bottom of the dispensing cylinder 10. The filter screen 1203 inside the transfer cylinder 1202 filters out impurities in the glue to avoid clogging the subsequent channels. The flow regulating valve 1204 connected to the bottom of the transfer cylinder 1202 is electrically connected to the automatic controller 2. The parameters are set to precisely control the flow rate and total amount of the adhesive. Finally, the adhesive flows out from the conical dispensing head 1205 and evenly covers the target dispensing area of ​​the watch. When the dispensing operation is completed and the device is in a non-working state, the electric cylinder 1301 embedded in the bracket 3 drives the adhesive receiving tube 1302 at the telescopic end to move directly below the dispensing head 1205 to catch any dripping adhesive and prevent contamination of the dispensing table 1 and the watch processing parts. The cap 1303 at the bottom of the adhesive receiving tube 1302 can be removed at any time for easy cleaning of the collected adhesive. Under the unified control of the automatic controller 2, all structures work together to achieve precise control of the dispensing position, angle, and flow rate, ensuring the stability and efficiency of the processing flow.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
