[0022] See also Figures 1 to 5 As shown, a device for preventing loss of measuring auxiliary tools in an automobile production workshop comprises: a cabinet 1, in which six tool tray components, a circuit system, and a wireless signal transmitting device are arranged;

[0023] Each tool tray assembly includes: an accessory tray 2 and an induction switch tray 3; the accessory tray 2 and the induction switch tray 3 are arranged in parallel vertically, and both sides of the accessory tray 2 and the induction switch tray 3 are supported by tracks arranged on the side walls of the cabinet 1; the accessory tray 2 is used to classify and hold auxiliary measurement tools, and is an aluminum frame 21 with EVA foam having hollow holes 22 sandwiched in the middle; each accessory tray 2 is provided with a handle 23 at one end facing the outside of the cabinet 1, which is convenient for pushing and pulling tools. The induction switch tray 3 is a hollow aluminum tray for installing induction switches, and the hollow holes 31 thereon are consistent with the hollow holes 22 on the accessory tray 2; the induction switch tray 3 is arranged below the accessory tray 2 to ensure that one tool to be inspected corresponds to one induction switch, and the upper and lower positions are consistent;

[0024] The circuit system includes: a conversion power supply (220v to 24v) and a plurality of induction units;

[0025] Each of the sensing units corresponds to a tool tray assembly; each sensing unit includes: a plurality of sensing switches (NPN normally closed switches), an intermediate relay, a red indicator light 41 and a green indicator light 42; a plurality of sensing switches are connected in parallel, and the signal line after the parallel connection is connected to the negative pole of the coil of the intermediate relay, the open end of the intermediate relay is connected to the red indicator light, and the closed end of the intermediate relay is connected to the green indicator light; the positive pole of the coil of the intermediate relay, the red indicator light and the green indicator light are all connected to the wireless transmitter;

[0026] It also includes a wireless receiving device; the wireless transmitting device is communicatively connected with the wireless receiving device.

[0027] The power switch 5 is arranged on the back side of the cabinet 1. A cabinet door 6 is also arranged on the back side of the cabinet 1.

[0028] As long as there are objects to be inspected that have not been put back in place, the corresponding induction switch will be in the normally closed state, the corresponding intermediate relay coil will be in the on state, and the red indicator light connected to the normally open end of the intermediate relay will be on (the green light will be off); only when the auxiliary tray is full of objects to be inspected, all the induction switches will be in the normally open state, at this time the negative pole of the intermediate relay coil will be disconnected and stop working, and the green indicator light connected to the normally closed end of the intermediate relay will be on (the red light will be off).

[0029] The on / off signals of the six sensing units are synchronously transmitted to the wireless signal transmitter through the intermediate relay. The transmitter transmits the signal to the receiving end (the receiving end can be placed in the office or other places for easy management according to actual work needs). The receiving end can group the six signals according to actual needs. In this device, the six signals are divided into two groups, that is, 1-2-3-4-5 is a group named CMM2, and these five independent signals are connected in series to output green lights and in parallel to output red lights; 6 channels are a separate group named CMM3, which also outputs red and red lights.

[0030] The utility model fundamentally realizes the conversion from manual inspection to automatic equipment inspection, which greatly reduces the labor intensity of employees and improves work efficiency; at the same time, the administrator can pay attention to the working conditions on site at any time and supervise them in time, which plays a good fool-proofing role in actual use.

[0031] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
