Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to an automated watch polishing device. Background Technology

[0002] Machining refers to the process of altering the shape, size, or properties of a workpiece using mechanical equipment to ultimately obtain the desired product. Grinding and polishing are important machining methods. Polishing refers to the process of reducing the surface roughness of a workpiece using mechanical, chemical, or electrochemical methods to obtain a bright and smooth surface. It involves using polishing tools, abrasive particles, or other polishing media to refine the surface of a workpiece. In recent years, with technological advancements, the cost of various products such as mobile phones, smartwatches, tablets, and VR glasses has decreased, leading to their widespread adoption. When purchasing products, users pay more attention to appearance in addition to the product's functionality. For example, in the watchmaking process, to ensure aesthetic appeal, the surface of the product needs to be treated, such as creating brushed textures and polishing. Traditional operations are generally carried out in separate steps. For instance, after brushing is completed, the finished products are collected and transferred to another section for polishing. This results in poor operational continuity, long transfer times, and low efficiency. Furthermore, polishing now relies on manual operation, which can easily lead to excessive wear on the product. Utility Model Content

Detailed Implementation

[0027] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] Reference Figures 1 to 8 This utility model provides an automated watch polishing device, including a housing 1, a cover 11 mounted on the housing 1, a turntable mechanism 2 mounted on the housing 1, and a robotic arm 12 mounted on the housing 1. The turntable mechanism 2 has four workstations, one of which, near the robotic arm 12, has a dripping mechanism 4 above it. Each of the four workstations on the turntable mechanism 2 has a floating mechanism 5, which respectively houses a first wire-drawing polishing mechanism 6, a flexible belt polishing mechanism 7, a second wire-drawing polishing mechanism 8, and a disc polishing mechanism 9. The four workstations are evenly distributed, allowing the turntable mechanism 2 to rotate one workstation at a time, i.e., ninety degrees. The housing 1 has a product placement area 13 and a tool placement area 14, located on either side of the robotic arm 12.

[0029] The floating mechanism 5 includes a base plate 51, a floating guide rail assembly 52 disposed on the base plate 51, a floating seat 53 disposed on the floating guide rail assembly 52, and a force feedback assembly 54. The floating guide rail assembly 52 specifically includes two mounting seats, a guide rod connected between the two mounting seats, and a floating block connected to the guide rod. The floating block has an air vent and is driven by gas. The force feedback assembly 54 includes a force feedback bracket 541 disposed on the base plate 51, a force sensor 542 disposed on the force feedback bracket 541, and a sensing element 543 connected to the floating seat 53 and matching the force sensor 542. During the polishing process, when the product comes into contact with the corresponding mechanism, a contact force is generated. This force pushes the floating seat 53 to move along the floating guide rail assembly 52, thereby causing the force feedback bracket 541 to press against the force sensor 542. The force sensor 542 can thus measure the magnitude of the contact force and provide feedback to the equipment's control system. After receiving the signal from the force sensor 542, the equipment's control system will judge and analyze the actual contact force according to the preset force value range. If the detected force value deviates from the preset range, the control system will issue an alarm message indicating that the current product pressure is too high, and at the same time notify the staff to handle it, or automatically adjust to achieve self-adaptation.

[0030] Both the first wire drawing and polishing mechanism 6 and the second wire drawing and polishing mechanism 8 include a first support base 61 mounted on the floating seat 53, a first motor 62 mounted on the first support base 61, a rotating shaft 63 connected to the output end of the first motor 62, and a processing wheel 64 mounted on the rotating shaft 63. One or more processing wheels 64 can be provided. Furthermore, the first wire drawing and polishing mechanism 6 and the second wire drawing and polishing mechanism 8 can be flexibly adjusted according to actual processing needs. For example, if the product requires wire drawing, the first wire drawing and polishing mechanism 6 can be used as a wire drawing module, and the second wire drawing and polishing mechanism 8 can be used as a polishing module. That is, the processing wheel 64 of the first wire drawing and polishing mechanism 6 can be set to a metal wheel, plastic wheel, fiber wheel, or other material suitable for wire drawing and polishing, while the processing wheel 64 of the second wire drawing and polishing mechanism 8 can be set to a material suitable for polishing, such as cotton.

[0031] The flexible belt polishing mechanism 7 includes a second support base 71 mounted on a floating seat 53, a polishing bracket 72 connected to the second support base 71, a second motor 73 mounted on the polishing bracket 72, a drive wheel 74 connected to the second motor, a tension wheel 75 connected to the polishing bracket 72, and a polishing belt 76 connected to the drive wheel 74 and the tension wheel 75. The second motor 73 drives the polishing belt 76 to rotate via the drive wheel 74 to polish the product.

[0032] A swing arm 77 is rotatably connected to the polishing bracket 72. A swing wheel 78 is mounted on the swing arm 77. A buffer 79 is connected between the end of the swing arm 77 and the polishing bracket 72. The swing wheel 78 is connected to the polishing belt 76. The drive wheel 74, swing wheel 78, and tension wheel 75 make the polishing belt 76 form a triangle. When the contact force between the product and the polishing belt 76 is too great, the buffer 79 retracts, causing the swing arm 77 to rotate, loosening the belt, thus relieving pressure and preventing excessive wear on the product. Alternatively, the swing arm 77 and swing wheel 78 can also be used as a structure for tensioning the polishing belt 76. For example, the buffer 79 can be set as a telescopic rod; adjusting the telescopic rod adjusts the angle of the swing arm 77, thereby opening the polishing belt 76 for tension.

[0033] The disc polishing mechanism 9 includes a third support base 91 mounted on the floating base 53, a third motor 92 mounted on the third support base 91, a support plate 93 mounted on the floating base 53, and two polishing discs 94 mounted on the support plate 93. The third motor 92 is connected to the two discs via a synchronous pulley set 95. The two polishing discs 94 can be made of different materials or have different mesh sizes to meet different fineness processing requirements.

[0034] The dripping mechanism 4 includes a dripping support 41 and at least one dripping tube 42 disposed on the dripping support 41. In this embodiment, the dripping support 41 is connected to the machine cover 11, the dripping tube 42 is a universal tube, and the dripping tube 42 is connected to a liquid supply device to provide coolant or grinding fluid to the product during processing.

[0035] The automated watch polishing equipment includes a wax spraying mechanism 10, which includes a wax spraying bracket 10a, a fixed head 10b connected to the wax spraying bracket 10a, and a wax spraying gun 10c mounted on the fixed head 10b. The wax spraying gun 10c corresponds to the processing wheel 64 and can spray wax onto the product during polishing or wire drawing.

[0036] The automated watch polishing equipment includes a water curtain circulation mechanism 3, which comprises a circulation filter box 31, a circulation pipe assembly 32 connected to the circulation filter box 31, and several water curtain boxes 33 disposed on the housing 11. The outlet of the circulation pipe assembly 32 extends above the water curtain boxes 33. There is a gap between the bottom plate 51 of the water curtain box 33 and the inner wall of the housing 11. The bottom plate 51 of the water curtain box 33 has a downward slope at its edge, so that when water flows from the slope to the aforementioned gap, a water curtain is formed to isolate the processing area. A large amount of dust is generated during the polishing process. The water curtain can effectively absorb the dust, reducing the dust content in the air. The water curtain can also isolate the polishing area from other areas to a certain extent, reducing noise and dust diffusion, improving the working environment. Simultaneously, the polishing process generates heat, and the water curtain can cool the equipment and protect the operators.

[0037] The circulating filter box 31 is equipped with a drum filter mechanism 34, and a drain pipe 35 is provided below the machine cover 11, which is connected to the drum filter mechanism 34. Specifically, the bottom of the machine cover 11 has a water collection structure, such as a water collection tank, which collects the water flowing down from the water curtain box 33 into the drain pipe 35. After the water enters the drum filter mechanism 34 from the drain pipe 35 to filter out dust and lint, it returns to the top of the machine cover 11 under the action of the water pump through the circulating pipe assembly 32 and flows back into the water curtain box 33, completing the recycling.

[0038] During processing, each mechanism can be adapted to the processing requirements of the product. For example, if the product requires wire drawing, the processing wheel 64 of the first wire drawing and polishing mechanism 6 can be replaced with a type suitable for wire drawing operations. The flexible belt polishing mechanism 7, the second wire drawing and polishing mechanism 8, and the disc polishing mechanism 9 can be used as multi-stage polishing processes, or they can be used to deal with different parts of the product, or they can be set to multi-stage polishing with different fineness from coarse polishing to fine polishing. They are flexible and versatile. The robot arm 12 is a multi-axis robot arm 12, which can be connected to the gripping mechanism of the corresponding product. After gripping the product, it moves to the workstation of the turntable mechanism 2 near the robot arm 12 for processing. After the processing of the current mechanism is completed, the turntable mechanism 2 rotates to replace the next mechanism, and so on.

[0039] The automated watch polishing equipment features a control system within its industrial computer. Working in conjunction with the robotic arm 12 and the floating mechanism 5, it precisely controls the polishing force and angle. This ensures that the watch is not over-polished or damaged during the polishing process, and allows for customized polishing treatments for different parts. Whether it's a complexly shaped watch case or a delicate section of the strap, the polishing operation is accurate, ensuring a uniform and consistent finish on every part. The automated watch polishing equipment can be programmed with different polishing process parameters based on the product's material, style, and polishing requirements, and the corresponding mechanisms can be adjusted (such as changing the processing wheel 64, polishing belt 76, polishing disc 94, etc.). This allows the equipment to adapt to various watch polishing needs, improving its versatility and flexibility. The automated watch polishing equipment boasts high efficiency and stable performance, capable of continuous long-term operation without fatigue or errors. Compared to traditional manual polishing methods, it significantly improves work efficiency and shortens the watch polishing cycle.
