Description

Technical Field

[0001] The invention relates to a testing device, in particular to an online electric toothbrush semi-finished product assembly testing device. Background Art

[0002] Previously, the standardized test fixtures, working condition simulation test fixtures and jumper soldering for testing the internal components of electric toothbrushes were usually done manually. Each station required an operator, standing side by side to form an assembly line. Each operator first took an electric toothbrush internal component from the previous station, and after completing his work, he passed the electric toothbrush internal component to the next station.

[0003] The operation of the standardized test station and the working condition simulation test station is very similar. The operator puts the internal components of the electric toothbrush into the test fixture, waits for the test fixture to complete the work, and then passes the internal components of the electric toothbrush to the operator of the next station or puts them into the defective product collection box according to the results displayed on the computer screen.

[0004] The job of the jumper welding station is to use soldering equipment to weld together a battery jumper point of the electric toothbrush.

[0005] However, the existing operations have the following disadvantages:

[0006] The work of the existing standardized test fixture stations and simulated working condition test fixture stations is very simple. Operators spend most of their time waiting for the fixture to work, and their efficiency is very low. If an operator operates two fixtures at the same time, confusion is likely to occur, leading to misoperations such as missed tests, repeated tests, and mistaking defective products for good products. If a station uses two identical fixtures, the production capacity of the previous and next stations cannot keep up.

[0007] The work of the existing jumper welding station is also very simple. The time to weld a jumper point of the internal components of an electric toothbrush is very short, so the operator spends most of the time waiting for the internal components of the electric toothbrush; and the fumes produced by the soldering are harmful to the human body. The high temperature generated by the soldering equipment is also prone to burn accidents. Summary of the invention

[0035] After the operator starts the test software in the cantilever operation box 13, the operator starts the equipment and waits for the equipment initialization to be completed.

[0036] The operator places the internal components of the electric toothbrush into the tray 3 on the feeding station 4 and leaves the safety light curtain. After the laser displacement sensor 2 checks that the internal components of the electric toothbrush are placed correctly, the code of the tray 3 is obtained through the radio frequency reader and bound to the internal components of the electric toothbrush. The tray 3 is then transferred to the working station. At the same time, the reflow station 6 releases an empty tray 3 to the feeding station 4.

[0037] The tray 3 carrying the internal components of the electric toothbrush first arrives at the standardized test fixture 7. The standardized test fixture 7 first fixes the tray 3 and the internal components of the electric toothbrush through the fixing frame 77 and the fixture 78 in the fixing frame 77, and loads the dummy load loader 75 to the head of the internal components of the electric toothbrush. Finally, the test box 73 is connected to the internal components of the electric toothbrush and vibrates it. The high-precision laser displacement sensor detects the angle and frequency of the vibration of the internal components of the electric toothbrush. After the test is completed, the standardized test fixture 7 binds the test result with the code of the tray 3, and then releases the internal components of the electric toothbrush and the tray 3 to the simulated working condition test fixture 8. At the same time, the feeding station 4 releases a tray 3 carrying the internal components of the electric toothbrush to the station.

[0038] The tray 3 carrying the internal components of the electric toothbrush arrives at the simulated working condition test fixture 8. The simulated working condition test fixture 8 first fixes the tray 3 and the internal components of the electric toothbrush through the product front claw cylinder 87, and loads the dummy load loader 2 85 to the head of the internal components of the electric toothbrush.

The standardized test fixture 7 releases a tested internal component of the electric toothbrush and the tray 3 to the station.

[0039] The tray 3 carrying the internal components of the electric toothbrush arrives at the three-axis soldering platform 9. The three-axis soldering platform 9 first fixes the tray 3 and the internal components of the electric toothbrush through the solder positioning frame 93. The three-axis moving device 91 moves the automatic soldering machine 92 to the jumper welding points of the internal components of the electric toothbrush.
