Description

Technical Field

[0001] This invention relates to the field of precision parts dimension inspection technology, specifically to a device for identifying the travel dimension of a stainless steel watch case button and its usage method. Background Technology

[0002] Stainless steel watch cases are widely used in the watchmaking industry due to their excellent corrosion resistance, wear resistance, and aesthetic appeal. As a key operating component of a watch, the travel distance of the pushers directly determines their feel, responsiveness, and lifespan. Excessive push distance leads to redundant operation and a loose feel; insufficient travel distance can cause problems such as button jamming and malfunction. Therefore, high-precision testing of the pusher travel distance in stainless steel watch cases is an indispensable quality control step in the watchmaking process.

[0003] Currently, the industry mainly relies on two methods to inspect the travel distance of stainless steel watch case buttons: one is manual inspection, where inspectors manually push the buttons and read the values ​​using tools such as dial indicators and vernier calipers. This method is not only inefficient, but also susceptible to human factors such as operator habits and visual fatigue, making it difficult to guarantee inspection accuracy, and it cannot meet the inspection needs of large-scale mass production; the other is semi-automated inspection equipment. Although this type of equipment achieves some mechanical operation, it still requires manual positioning and clamping of the watch case and manual recording and screening of inspection data, resulting in problems such as insufficient positioning accuracy, poor data traceability, and discontinuous inspection process.

[0004] For example, a precision parts stroke detection device disclosed in the prior art uses a cylinder to push the detection probe to contact the workpiece and collects data through a displacement sensor. However, this device does not have a dedicated positioning mechanism designed for the irregular structure of the stainless steel watch case, which makes the watch case prone to displacement during the detection process and results in a large detection error. At the same time, its data processing module can only realize simple numerical display and cannot complete the automatic analysis, screening and storage of data. It requires manual intervention in subsequent data processing, which increases the production cycle and labor costs.

[0005] In view of the shortcomings of the existing technology, there is an urgent need for a stainless steel watch case key travel dimension recognition device with automatic positioning, high-precision detection, automatic data processing and traceability functions, so as to solve the problems of low efficiency, poor accuracy and low degree of automation of the existing detection methods. Summary of the Invention

[0006] The purpose of this invention is to provide a device for identifying the travel dimension of stainless steel watch cases and its usage method. This device has the advantages of simple structure and reasonable design, overcoming the defects of low efficiency, poor accuracy and low automation in the detection of the travel dimension of stainless steel watch cases in the prior art.

Then, the measurement software installed in the controller quickly captures the outline image of the object according to the pre-programmed instructions and compares it with the size scale formed by the tiny pixels of the camera to calculate the size and shape parameters of the object. The measurement software evaluates the dimensional tolerance of the calculation results and generates a measurement report. The workpiece size can be judged to be qualified by the measurement report data or by whether the indicator switch is lit up with a green light. ④ Feedback: When the measurement result of the stainless steel case exceeds the preset threshold, the controller transmits an electrical signal to the indicator light and the buzzer, causing the indicator light to light up and the buzzer to emit an alarm signal.

[0043] A method for using a stainless steel watch case button travel dimension recognition device includes the following steps: ① Positioning: First, the stainless steel watch case is placed on the positioning seat 32. The positioning hole at the bottom of the stainless steel watch case engages with the positioning pin 35. At the same time, the stainless steel watch case is connected to multiple positioning posts 33. Then, multiple actuators 36 are driven to work simultaneously, causing multiple clamping blocks 37 to contact and connect with various parts of the surface of the stainless steel watch case, thus achieving complete positioning of the stainless steel watch case. The positioning mechanism 3 uses the positioning pin 35 and multiple positioning posts 33 to achieve initial positioning. Subsequently, multiple actuators 36 drive multiple clamping blocks 37 to precisely clamp the stainless steel watch case. At the same time, the anti-slip pad 38 provides elastic support for the watch case, avoiding rigid contact that could cause deformation of the stainless steel watch case. This effectively improves the positioning accuracy of the stainless steel watch case and provides a guarantee for the accuracy of subsequent testing. ②Detection: Start the light source 41 to take pictures and measure the stainless steel case on the positioning seat 32. During the picture taking process, drive the motor 472 to adjust the height of the camera 43 as needed. The motor 472 drives the lead screw 473 to rotate, so that the slider 475 moves on the guide rail 474, which in turn drives the camera 43 and the light guide cover 44 to move and adjust the distance between the camera 43 and the stainless steel case. ③ Processing: After taking the photo and measuring the file, it is transmitted to the data storage module in the controller 51. The controller 51 performs preprocessing such as noise reduction and enhancement on the image. Then, the measurement software installed in the controller 51 quickly captures the outline image of the object according to the pre-programmed instructions and compares it with the size scale formed by the tiny pixels of the camera to calculate the size and shape parameters of the object. The measurement software evaluates the dimensional tolerance of the calculation results and generates a measurement report. The workpiece size can be judged to be qualified by the measurement report data or by whether the indicator switch 13 is lit up with a green light. ④ Feedback: When the measurement result of the stainless steel case exceeds the preset threshold, the controller 51 transmits an electrical signal to the indicator light 71 and the buzzer 72, causing the indicator light 71 to light up and the buzzer 72 to emit an alarm signal.

10. A method of using the stainless steel watch case key travel dimension recognition device according to any one of claims 1-9, characterized in that, Includes the following steps: ① Positioning: First, the stainless steel watch case is placed on the positioning seat (32). The positioning hole at the bottom of the stainless steel watch case is engaged with the positioning pin (35). At the same time, the stainless steel watch case is in contact with multiple positioning columns (33). Then, multiple drivers (36) are driven to work simultaneously to drive multiple clamping blocks (37) to contact and connect with various parts of the surface of the stainless steel watch case, so as to achieve complete positioning of the stainless steel watch case. ②Detection: Start the light source (41) to take pictures and measure the stainless steel watch case on the positioning seat (32). During the picture taking process, drive the motor (472) to adjust the height of the camera (43) as needed. The motor (472) drives the lead screw (473) to rotate, so that the slider (475) moves on the guide rail (474), thereby driving the camera (43) and the light guide cover (44) to move and adjust the distance between the camera (43) and the stainless steel watch case. ③ Processing: The image after taking a picture is transmitted to the data storage module in the controller (51).
