Technical Field

[0001] The invention relates to the technical field of detection devices, in particular to a mechanical timer automatic feeding device. Background Art

[0002] Although electronic timers have been invented for many years, mechanical timers are still widely used due to their high reliability, low price, easy operation, simple maintenance and many other advantages. Mechanical timers are widely used in various devices, such as washing machines, electric fans, microwave ovens, electric heaters and other household appliances, to set the running time of the equipment; in addition, mechanical timers are widely used in military equipment because of their characteristics of not being affected by electromagnetic interference, such as timers in artillery shells and bombs. In particular, the use of electromagnetic pulse bombs in modern warfare will cause some equipment to fail instantly. Therefore, mechanical timers have inherent characteristics and are not affected by electromagnetic interference at all, so they are still widely used in the military.

[0003] In the existing technology, the detection of mechanical timers is completely dependent on manual operation, which requires opening them one by one and placing them on the workbench. After a certain number and time, they are checked with the naked eye to distinguish OK and NG. This requires a lot of manpower, and the material loading is slow. In addition, errors may occur due to human reasons when observing with the naked eye. At the same time, robots in the existing technology have been widely used in the processing industry. After the program is set, the robots can automatically transfer the parts. How to combine this with the detection field of mechanical timers needs to be solved urgently. Summary of the invention

[0023] A support truss 10 is provided on one side of the detection platform 1, and a detection column 11 and a detection column 2 12 are provided on the support truss 10 in sequence. Both the detection column 11 and the detection column 2 12 are provided with a visual detection system for detecting the time of passing through the detection column 11 or the detection column 2 12.

[0024] An opening mold 13 is provided on the robot base 6. The opening mold 13 has the same shape as the placement mold 8. A starting device 14 for contacting and connecting a mechanical timer switch is provided in the opening mold 13. When the mechanical timer is placed in the opening mold 13, the starting device 14 is turned on and the mechanical timer is started at the same time.

[0025] The placement mold 8 and the opening mold 13 are both in a nine-square grid shape. A positioning recessed hole 15 is provided in the middle of the placement mold 8 or the opening mold 13 . The placement mold 8 or the opening mold 13 is provided with eight equal-sized component recessed holes 16 along the circumference of the positioning recessed hole 15 .

[0026] The starting device 14 includes an L-shaped elastic member 20, which is arranged in the inner wall of the component recessed hole 16. The horizontal lower end of the L-shaped elastic member 20 is connected to a pressing member 21. The pressing member 21 passes through the bottom of the component recessed hole 16. A spring member is provided at the bottom of the pressing member 21. A triangular sliding member 22 is provided at the top of the L-shaped elastic member 20.

Inspection column 1 and inspection column 2 are equipped with two visual camera systems respectively. Taking the 60-minute inspection timer as an example, when the switch is turned on for the first time and the material is discharged at 0 o'clock, the inspection column 1 moves 57 minutes ago to detect whether the 60-minute timer has any products reset in advance. At this time, it will imitate the robot's discharge time. After 63 minutes, the inspection column 2 moves to detect whether the 60-minute timer has any products that have timed out. After repeating the inspection 4 times, the robot grabs the products one by one onto the conveyor belt, automatically distinguishes good products from NG products, and places them in the corresponding area to complete a batch of inspections (the time interval can be adjusted, and the action time can be adjusted at any time according to the discharge speed detection error).

[0031] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
