Abstract

This utility model relates to the field of automated testing technology, specifically a mechanism for inspecting copper sheet weld defects in a faceplate. It includes a mounting base plate, a faceplate positioning ramp mounted on the top of the base plate via a support plate, upper and lower cylinders mounted on the back of the positioning ramp, an adjusting component mounted on the driving end of each cylinder, a cylinder mounting plate mounted on the movable part of the adjusting component, and front and rear cylinders mounted on the bottom of the mounting plate. A driving plate is mounted on the driving end of each cylinder, and a connecting component is mounted on the surface of the driving plate.

Description

Technical Field

[0001] This utility model relates to the field of automated testing technology, specifically a testing mechanism for poor solder joints on copper sheets in a faceplate. Background Technology

[0002] The main functions of a phone case include protecting the phone, enhancing its appearance, and providing additional functions. Besides protection and aesthetics, phone cases can also offer additional features such as stands and SIM card slots. During phone manufacturing, copper sheets are welded inside the case to ensure more stable and efficient signal transmission between internal components. This is crucial for the phone's communication functions, effectively shielding electromagnetic signals, reducing external electromagnetic interference on the phone's internal circuitry, and preventing signal leakage.

[0003] Currently, after the copper sheet of the faceplate is welded, it is necessary to check whether the welding pull force can meet the standard. The traditional method is to manually use tools to pick and check the welded copper sheet. This method has the problem that different inspectors have different pulling force, which leads to an increase in defective products and cannot meet the current demand for automated, efficient and accurate inspection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mechanism for inspecting copper sheet solder joint defects, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper sheet solder joint inspection mechanism, comprising a mounting base plate, a housing positioning inclined plate provided on the top of the mounting base plate via a support plate, upper and lower cylinders provided on the back of the housing positioning inclined plate, an adjusting component provided at the driving end of the upper and lower cylinders, a cylinder mounting plate provided on the movable part of the adjusting component, a front and rear cylinders provided at the bottom of the cylinder mounting plate, a driving plate provided at the driving end of the front and rear cylinders, a connecting component provided on the surface of the driving plate, and a test fork provided on one side of the connecting component via bolts.

[0006] Optionally, the front side of the faceplate positioning ramp is provided with multiple positioning pins.

[0007] Optionally, the top of the adjusting member is provided with a Z-direction adjusting bolt, one side of the adjusting member is provided with an X-direction adjusting bolt, and the back of the adjusting member is provided with a Y-direction adjusting bolt.

[0008] Optionally, the number of test forks is adapted to the number of copper sheets on the faceplate.

[0009] Optionally, the faceplate positioning ramp is inclined upwards to facilitate inspection personnel or visual cameras to observe the inspection process.

[0010] Optionally, the surface of the faceplate positioning inclined plate is also provided with adsorption holes for adsorbing the faceplate.

[0011] This utility model provides a mechanism for inspecting poor solder joints in copper sheets of a faceplate, which has the following beneficial effects: This copper sheet weld defect inspection mechanism uses front and rear cylinders to drive a test fork to insert into the inside of the welded copper sheet on the faceplate. Upper and lower cylinders then drive the test fork to move the copper sheet. If the copper sheet has a weld defect, the test fork will push it open; if it does not, the cylinders will not push it open, indicating an OK result. This achieves automatic inspection of copper sheet weld defects, effectively improving inspection efficiency. Its constant inspection pull force ensures the copper sheet pull force is within the required range, effectively avoiding the increase in defective products caused by inconsistent manual pulling force. The Z-axis, X-axis, and Y-axis adjustment bolts on the adjustment components allow for fine-tuning according to different products, effectively improving the mechanism's flexibility.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1 to 3 This utility model provides a technical solution: a copper sheet solder joint inspection mechanism, including a mounting base plate 1. A mounting base plate 1 is provided with a copper sheet positioning inclined plate 3 on the top of the mounting base plate 1 via a support plate 2. The copper sheet positioning inclined plate 3 is inclined upward to facilitate the inspection process by inspectors or visual cameras. Multiple positioning pins 4 are provided on the front of the copper sheet positioning inclined plate 3. The surface of the copper sheet positioning inclined plate 3 is also provided with adsorption holes 15 for adsorbing the copper sheet. The positioning pins 4 are used to fix the copper sheet through the adsorption holes 15 and position it. The back of the faceplate positioning inclined plate 3 is provided with upper and lower cylinders 5. The driving end of the upper and lower cylinders 5 is provided with an adjusting component 6. The top of the adjusting component 6 is provided with a Z-direction adjusting bolt 12, the side of the adjusting component 6 is provided with an X-direction adjusting bolt 13, and the back of the adjusting component 6 is provided with a Y-direction adjusting bolt 14. Through the Z-direction adjusting bolt 12, X-direction adjusting bolt 13 and Y-direction adjusting bolt 14 on the adjusting component 6, the mechanism can be finely adjusted in the XYZ three directions according to different products, effectively improving the flexibility and application range of the mechanism. The cylinder mounting plate 7 is mounted on the movable part of the adjusting part 6. The bottom of the cylinder mounting plate 7 is provided with front and rear cylinders 8. The driving end of the front and rear cylinders 8 is provided with a driving plate 9. The surface of the driving plate 9 is provided with a connecting part 10. One side of the connecting part 10 is provided with a test fork 11 by bolts. The number of test forks 11 is adapted to the number of copper sheets on the face shell. The front and rear cylinders 8 drive the test forks 11 to insert into the inner side of the copper sheet welded on the face shell. The upper and lower cylinders 5 drive the test forks 11 to move the copper sheet. If the copper sheet is poorly welded, the test fork 11 will push the copper sheet open. If the copper sheet is not poorly welded, the upper and lower cylinders 5 will not push the copper sheet open. The result is OK. This realizes automatic inspection of poorly welded copper sheets, which effectively improves inspection efficiency. Its inspection pull force is constant, which can ensure that the copper sheet pull force is within the required range and effectively avoid the situation where the manual pulling force is different, which leads to an increase in defective products.

[0016] In this invention, the working steps of the device are as follows: The faceplate is positioned on the faceplate positioning inclined plate 3 by the positioning pin 4 through the feeding device, and the faceplate is fixed by the adsorption hole 15. Then, the front and rear cylinders 8 are activated to drive the test fork 11 to insert into the inside of the copper sheet welded to the faceplate. The upper and lower cylinders 5 drive the test fork 11 to move the copper sheet. If the copper sheet is poorly welded, the test fork will push the copper sheet away. If the copper sheet is not poorly welded, the upper and lower cylinders 5 will not push the copper sheet away. The result is OK.
