Description

Technical Field

[0001] This utility model relates to the field of watch strap testing technology, and in particular to a high-density material watch strap disassembly and assembly testing machine. Background Technology

[0002] In the modern watch, smart wearable device, and precision instrument manufacturing industry, the watch strap, as a key component connecting the main structure and the wearer, directly affects the product's lifespan, wearing comfort, and overall safety. Especially with the widespread use of high-density materials in watch strap manufacturing, higher requirements are placed on the stability, insertion and extraction durability, and fatigue resistance of the connection structure between the watch strap and the watch body. To ensure that the product will not detach or be damaged due to connection failure during long-term use, the watch strap usually needs to undergo repeated disassembly and assembly cycle tests before leaving the factory to simulate wear, insertion and extraction force changes, and structural fatigue effects during actual wear. This test can not only evaluate the mechanical strength of the watch strap connection structure but also reflect its assembly accuracy and interchangeability.

[0003] Currently, there are some automated equipment on the market for testing watch strap installation and removal, which can realize the automatic installation, removal and mechanical performance testing of watch straps to a certain extent. However, the existing technology still has some shortcomings: most testing equipment only focuses on the mechanical performance testing and lacks simultaneous evaluation of the surface quality and structural integrity of the watch strap. Appearance defects such as scratches, cracks and coating peeling often rely on manual visual inspection, which results in low testing efficiency, inconsistent standards and easy to miss small flaws, making it difficult to meet the requirements of high-quality production.

[0004] Therefore, there is an urgent need for a high-density material strip testing machine with functions of disassembly and assembly performance testing and automatic identification of appearance defects. Utility Model Content

[0005] To overcome the shortcomings of existing watch strap disassembly and assembly testing equipment that lacks visual inspection functions and still relies on manual evaluation after watch strap testing, this utility model provides a high-density material watch strap testing machine with disassembly and assembly performance testing and automatic identification of visual defects.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a high-density watch strap disassembly and assembly testing machine, comprising a workbench, a watch rotating mechanism positioned in the center of the workbench surface, watch strap angle locking mechanisms mounted on the workbench surfaces on either side of the watch rotating mechanism, each watch strap angle locking mechanism equipped with a linear motor, and watch clamping mechanisms positioned diagonally in front of and behind the watch rotating mechanism, a display device positioned on the left rear side of the workbench surface, a control console positioned on the right rear side of the workbench surface, a light shield frame positioned on the workbench surface, a mounting plate positioned at the top of the light shield frame, and an industrial camera mounted on the mounting plate.

[0007] In one embodiment, the mounting plate is provided with a ring light, and the industrial camera is located at the center of the ring light.

[0008] In one embodiment, the bottom of the workbench is provided with symmetrically distributed guide frames, and a pull-out plate is slidably provided between the guide frames, the pull-out plate being able to slide back and forth along the guide frames.

[0009] In one embodiment, heat dissipation vents are provided on both the left and right sides of the lower part of the workbench.

[0010] In one embodiment, a filter screen is provided on the outside of each of the heat dissipation vents.

[0011] In one embodiment, a fan is provided inside each of the heat dissipation vents.

[0012] Compared with the prior art, this utility model has the following technical effects: 1. By setting up components such as a watch rotation mechanism, a watch strap angle locking mechanism, and a linear motor, the entire process of watch strap installation, tensile testing, and disassembly can be completed automatically, effectively replacing traditional manual operation, greatly improving testing efficiency and repeatability, and ensuring the consistency of testing conditions each time. In addition, after the test is completed, an industrial camera set in the light shield, together with a ring light, is used to collect images of the surface of the tested watch strap, and an image recognition system is used to automatically determine whether there are appearance defects such as scratches, cracks, and coating peeling, realizing dual inspection of performance and appearance, reducing manual intervention, and improving inspection accuracy.

[0013] 2. The workbench is equipped with a pull-out panel at the bottom for placing the keyboard, mouse and tools, which optimizes the human-computer interaction experience. In addition, the heat dissipation vents and fans on the left and right sides of the workbench, together with the filter screen, form an effective air circulation path to prevent the internal components from overheating, extend the service life of the equipment, and ensure the stability and reliability of the testing process.

Detailed Implementation

[0021] 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.

[0022] Example 1: Please refer to Figures 1-4A high-density watch strap disassembly and assembly testing machine includes a workbench 1. A watch rotating mechanism 2 is located in the center of the workbench 1. A watch strap angle locking mechanism 3 is located on the workbench 1 on both sides of the watch rotating mechanism 2. Each watch strap angle locking mechanism 3 is equipped with a linear motor 301 for driving it to move horizontally to achieve tensile testing. A watch clamping mechanism 4 is located diagonally in front of and diagonally behind the watch rotating mechanism 2 for positioning and clamping the watch to be tested placed on the watch rotating mechanism 2 during the test, ensuring its assembly and testing. To ensure stability during the process, a display device 5 is installed on the left rear side of the workbench 1, and a control console 501 is installed on the right rear side of the workbench 1. Operators can set the test parameters of each mechanism and monitor the test status through the control console 501. A light shield 6 is installed on the workbench 1, and a mounting plate 7 is installed at the top inside the light shield 6. An industrial camera 8 is installed on the mounting plate 7 to capture the surface image of the watch strap after the test for appearance defect detection. A ring light 9 is installed on the mounting plate 7, and the industrial camera 8 is located at the center of the ring light 9 to ensure uniform illumination during image acquisition and improve image recognition accuracy.

[0023] In use, the watch to be tested is first placed flat on the watch rotation mechanism 2. The control console 501 sends a command to the watch clamping mechanism 4 to clamp and limit the watch. Next, the two watch straps are placed on the strap angle locking mechanisms 3 on both sides, and these mechanisms adjust the straps to match the angle of the watch connection and clamp them in place. Then, the watch rotation mechanism 2 rotates the watch to an appropriate angle, engaging with one of the straps. The mechanism then rotates back to engage with the other strap. Next, the linear motor 301 drives the strap angle locking mechanism 3 outwards, applying a certain tension to the assembled straps to detect the connection strength between the straps and the watch and to check for any looseness, thereby evaluating the fit. To ensure reliability, during the disassembly of the watch strap, the linear motor 301 drives the watch strap angle locking mechanism 3 to reset inward, while the watch rotation mechanism 2 drives the watch to rotate, separating the watch strap from the watch, thus completing one complete disassembly and assembly cycle. Throughout the testing process, the watch strap can be repeatedly inserted and removed from the watch a set number of times. If the watch strap does not fall off or loosen after multiple insertions and removals, it is judged to be a qualified product. After the test is completed, the industrial camera 8 automatically captures an image of the watch strap surface with the assistance of a ring fill light, and transmits the image data to the display device 5 through the image transmission interface. The built-in image recognition system automatically analyzes and judges whether there are appearance defects such as scratches, cracks, and coating peeling on the watch strap surface, thereby realizing dual automated detection of watch strap performance and appearance.

[0024] Example 2: Based on Example 1, please refer to... Figure 2 and Figure 5 The workbench 1 has two guide frames 10 symmetrically distributed on the bottom of its surface. A pull-out plate 11 is slidably arranged between the two guide frames 10, and the pull-out plate 11 can slide back and forth along the guide frames 10.

[0025] In actual operation, operators need to frequently use input devices such as keyboards and mice to control the testing process, and may need to temporarily place auxiliary tools such as disassembly and assembly tools and testing fixtures. In order to improve the convenience of human-computer interaction and optimize the layout of the workspace, a pull-out plate 11 with a guide structure is set at the bottom of the workbench 1. The pull-out plate 11 slides and engages with the guide frame 10 on both sides, and can be freely pulled out or pushed in within a set range. When the operation starts, the operator can pull out the pull-out plate 11 to place the keyboard, mouse or other commonly used tools. After the test is completed, the pull-out plate 11 can be pushed back to its original position to avoid occupying the workspace and keep the work area clean and orderly.

[0026] Please see Figure 2 and Figure 6 The workbench 1 has heat dissipation vents on both the left and right sides of its lower part. Each heat dissipation vent is equipped with a filter screen 12 on the outside to prevent external dust from entering the equipment. Each heat dissipation vent is equipped with a fan 13 on the inside.

[0027] In this device, the wiring of key components such as the watch rotation mechanism 2, the watch strap angle locking mechanism 3, the linear motor 301, the watch tightening mechanism 4, and the display device 5 is centrally arranged at the lower part of the workbench 1. During long-term operation, a certain amount of heat will be generated. In order to prevent the equipment from affecting the testing accuracy or shortening its service life due to excessive temperature, a heat dissipation vent is set up and a fan 13 is used for heat dissipation. When the fan 13 is running, the hot air inside the equipment is discharged from the heat dissipation vent and the external cold air is guided to enter from the opposite side, thereby forming a continuous air circulation path inside the equipment, effectively reducing the internal temperature, maintaining the system operation within a safe range, and ensuring the stability and reliability of the testing process.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
