Abstract
Description
Technical Field
[0001] This utility model relates to the field of watch strap production technology, specifically a tooling fixture for inspecting steel sheets in watch straps. Background Technology
[0002] In today's watchmaking industry, to enhance the wearer's experience, an increasing number of watch straps are using magnetic steel plates. These magnetic steel plates not only make the watch strap more easily adhere to the wrist during wear but also enhance stability between the strap and the wrist. However, with the widespread use of magnetic steel plates in watch straps, quality inspection issues are becoming increasingly prominent.
[0003] Currently, in the production process of watch band steel plates, the inspection of the steel plates largely relies on manual operation. Because steel plates are magnetic, the correct orientation of the magnetic poles is crucial to the performance of the watch band. However, manual inspection makes it difficult to accurately determine whether the magnetic pole orientation of the steel plates meets design requirements. This makes it difficult to ensure that the magnetic pole orientation of each steel plate is accurate. If a steel plate with an incorrect magnetic pole orientation is assembled into a watch band, it will not only affect the watch band's adhesion, leading to a loose fit, but may also interfere with other magnetic components inside the watch, affecting its normal operation.
[0004] In order to accurately and efficiently detect the magnetic pole orientation of steel sheets, prevent steel sheets with incorrect magnetic pole orientation from being assembled into watch straps, and ensure product quality, we propose a tooling fixture for detecting steel sheets in watch straps. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a tooling fixture for inspecting steel plates in watch bands. It can accurately and efficiently detect the magnetic pole orientation of the steel plates, preventing steel plates with incorrect magnetic pole orientation from being assembled into watch bands and ensuring product quality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A tooling fixture for testing the steel strip of a watch band includes a mounting box on which a fluxmeter is mounted. A placement platform is fixedly connected to the top of the mounting box, and a magnetic sensor is mounted on the placement platform.
[0007] Preferably, an indicator light and a buzzer are provided on the top of the mounting box.
[0008] Preferably, a connecting plate is fixedly connected to the top of the mounting box, a support rod is fixedly connected to the top of the connecting plate, a connecting block is fixedly sleeved on the support rod, a mounting plate is fixedly installed on the rear side of the connecting block, and a CCD barcode scanner is provided on the front side of the mounting plate.
[0009] Preferably, the CCD barcode scanner is threaded with a connecting bolt on the rear side, and the mounting plate has a mounting groove that matches the connecting bolt, and the connecting bolt is movably connected to the mounting groove.
[0010] Preferably, the top of the placement platform has a positioning groove that matches the shape of the watch strap.
[0011] Preferably, the mounting box is provided with several sets of connection ports, and the CCD barcode scanner is provided with a data transmission line.
[0012] Beneficial effects This utility model provides a tooling fixture for inspecting the steel strips of watch bands. Compared with the prior art, it has the following advantages: This tooling fixture for testing watch band steel plates uses a magnetometer on the mounting box to measure the magnetic flux of the steel plate and a magnetic sensor on the placement table to determine the magnetic pole direction. This allows operators to complete the test accurately and quickly, avoiding problems such as poor watch band adhesion and insecure wearing due to incorrect magnetic pole direction. It also prevents incorrect steel plates from interfering with other magnetic components inside the watch and affecting its normal operation, further ensuring product quality.

[0015] 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.
[0016] Please see Figure 1-4This utility model provides a technical solution: a tooling fixture for testing steel strips on watch bands, including a mounting box 1, a magnetometer mounted on the mounting box 1, a placement platform 9 fixedly connected to the top of the mounting box 1, and a magnetic sensor mounted on the placement platform 9.
[0017] The top of the mounting box 1 is equipped with an indicator light 7 and a buzzer 8.
[0018] In use, the watch strap to be tested is placed on the placement platform 9. The magnetic flux of the steel sheet can be measured by the magnetometer on the mounting box 1, and the magnetic pole direction can be determined by the magnetic sensor on the placement platform 9. If the magnetic pole direction is correct, the indicator light 7 emits a green light; if the magnetic pole direction is incorrect, the indicator light 7 emits a red light, and the buzzer 8 sounds an alarm. Combined with the magnetic flux measurement data, the operator can accurately and quickly detect the magnetic pole direction of the steel sheet, preventing steel sheets with incorrect magnetic pole direction from being assembled into the watch strap. Combined with the magnetic flux measurement data, product quality is further guaranteed.
[0019] A connecting plate 2 is fixedly connected to the top of the mounting box 1. A support rod 4 is fixedly connected to the top of the connecting plate 2. A connecting block 3 is fixedly sleeved on the support rod 4. A mounting plate 5 is fixedly installed on the rear side of the connecting block 3. A CCD barcode scanner 6 is set on the front side of the mounting plate 5.
[0020] Using a CCD barcode scanner to scan the barcode on the steel sheet allows for the correlation between product information and testing data, facilitating intelligent and data-driven production.
[0021] The CCD barcode scanner 6 has a connecting bolt 13 threaded on its rear side. The mounting plate 5 has a mounting groove 14 that matches the connecting bolt 13. The connecting bolt 13 is movably connected to the mounting groove 14.
[0022] The position of the CCD barcode scanner 6 can be flexibly adjusted by the cooperation of the connecting bolt 13 and the mounting groove 14, so that the CCD barcode scanner 6 can be placed in a suitable position above the placement platform 9, ensuring that the scanning process can be carried out smoothly.
[0023] The top of the placement platform 9 has a positioning groove 12 that matches the shape of the watch strap. This facilitates determining the position of the watch strap during testing and prevents improper placement from affecting the test results.
[0024] The mounting box 1 is equipped with several sets of connection ports 10, and the CCD barcode scanner 6 is equipped with a data transmission line 11. These are used to upload the detection data to the system for analysis and processing.
[0025] Working Principle: During use, the watch strap to be tested is placed in the positioning slot 12 on the top of the placement platform 9 to determine its position and prevent improper placement from affecting the test results. The magnetic flux of the steel sheet can be measured by the magnetometer on the mounting box 1, and the magnetic pole direction can be determined by the magnetic sensor on the placement platform 9. If the magnetic pole direction is correct, the indicator light 7 emits a green light; if the magnetic pole direction is incorrect, the indicator light 7 emits a red light and the buzzer 8 sounds an alarm. Combined with the magnetic flux measurement data, the operator can accurately and quickly detect the magnetic pole direction of the steel sheet, preventing incorrect steel sheets from being assembled and ensuring product quality. At the same time, the CCD barcode scanner 6 scans the barcode on the steel sheet. The position of the CCD barcode scanner 6 can be flexibly adjusted by the cooperation of the connecting bolt 13 and the mounting slot 14 to ensure smooth scanning. After scanning, the product information can be matched with the test data. Then, the test data is uploaded to the system for analysis and processing through several sets of connection ports 10 on the mounting box 1 and the data transmission line 11 on the CCD barcode scanner 6, thereby facilitating intelligent and data-driven production.
