[0001] The utility model belongs to the technical field of circuit breaker production, and in particular relates to a coding device for a circuit breaker production line. Background Art

[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions, and can close, carry, and interrupt current under abnormal circuit conditions within a specified time. In the production process of circuit breakers, inkjet coding is an important link, the purpose of which is to identify the model, specifications, production date, batch, and other information of the circuit breaker.

[0003] When an existing circuit breaker production line uses a coding device to inkjet the circuit breaker through a coding gun, the coding gun generates a certain impact force on the circuit breaker when spraying ink. Therefore, for some circuit breakers with smaller specifications and narrower widths, the impact force generated by the ink jetting gun may cause them to fall over, resulting in the coding surface of the circuit breaker not being able to face upward, so that the subsequent curing process of the ink on its surface will be affected to a certain extent. In view of this, the present utility model is specially proposed. Utility Model Content

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0019] Example 1:

[0020] Reference Figure 1-Figure 3 The coding device for the circuit breaker production line includes: an electric telescopic rod 3, which is installed on the circuit breaker conveyor line 1 through a bracket 2; a lifting plate 4, which is fixedly connected to the telescopic end of the electric telescopic rod 3; a guide rod 5, which is fixedly connected to the lifting plate 4 and is located on both sides of the electric telescopic rod 3, and the guide rod 5 is slidably connected to the bracket 2; a concave positioning plate 603, which is installed on the lower side of the lifting plate 4 through a support rod; a coding gun 7, which is fixedly connected to the middle position of the concave positioning plate 603, and the coding end faces downward toward the conveyor line 1.

[0021] The support rod includes a sleeve 6, a connecting rod 601 and a tensioning spring 602. The sleeve 6 is symmetrically fixedly connected to both sides of the lifting plate 4. The connecting rod 601 is slidably connected in the sleeve 6, and the lower end is fixedly connected to the concave positioning plate 603. The tensioning spring 602 is arranged in the sleeve 6, and the two ends of the tensioning spring 602 are respectively connected to the sleeve 6 and the connecting rod 601.

[0022] Protective cushions 604 are fixedly connected to both sides of the lower end of the concave positioning plate 603 .

[0023] When the production of the circuit breaker is completed, it is necessary to perform coding on its surface. At this time, the staff can place the circuit breaker on the conveyor line 1 at one time, and then start the conveyor line 1 to make the conveyor line 1 convey the circuit breaker to the device. When the circuit breaker moves to the bottom of the coding gun 7, the circuit breaker can be stopped, and then the electric telescopic rod 3 can be started to control the coding gun 7 to move downward through the lifting plate 4. In the process of the coding gun 7 moving downward, the concave positioning plate 603 will first contact the circuit breaker to perform a positioning operation on the circuit breaker. Among them, when the concave positioning plate 603 contacts the circuit breaker, the distance between the coding gun 7 and the circuit breaker is exactly the specified distance. Then continue to control the lifting plate 4 to move downward. At this time, the tensioning spring 602 will be tightened due to pressure. The line contracts, and at the same time, the tensioning spring 602 will also exert a downward reaction force on the concave positioning plate 603 through the connecting rod 601, so that the concave positioning plate 603 can be closely contacted with the circuit breaker, thereby improving the stability of the circuit breaker positioning. The arrangement of the tensioning spring 602 and the protective cushion 604 can protect the circuit breaker and prevent the concave positioning plate 603 from causing pressure damage to the circuit breaker. When the positioning of the circuit breaker is completed, the inkjet printer 7 can be started at this time, and the inkjet printer 7 will spray the specified characters on the surface of the circuit breaker, thereby completing the inkjet printing operation on the circuit breaker. Then, the concave positioning plate 603 is controlled to leave the circuit breaker, and the conveyor line 1 is started to convey the next circuit breaker, and the inkjet printing operation can be performed on the next circuit breaker.

[0024] It should be noted that, in actual use, an identifier and a pressure sensor may be provided in the device so that the main controller knows that the circuit breaker has moved directly below the inkjet printer 7 and the pressure exerted by the concave positioning plate 603 on the circuit breaker.

[0025] Example 2:

[0026] Reference Figure 1-Figure 3 , a coding device for a circuit breaker production line is basically the same as that of Example 1, except that: one end of the connecting rod 601 located in the sleeve 6 is fixedly connected to a piston, and an annular gas storage shell 607 is fixedly connected to the concave positioning plate 603. The annular gas storage shell 607 is sleeved on the outside of the coding gun 7, and a plurality of nozzles 608 are connected to the lower side of the annular gas storage shell 607 at equal intervals in a circle. The nozzles of the nozzles 608 are tilted downward, and an air inlet and an air outlet are opened on one side of the sleeve 6. A one-way valve is provided in the air inlet and the air outlet of the sleeve 6. The air inlet and the air outlet of the sleeve 6 are respectively connected to an exhaust pipe 605 and an air supply pipe 606, and the air outlet of the air supply pipe 606 is connected to the air inlet of the annular gas storage shell 607.

[0027] When the concave positioning plate 603 moves downward and contacts the circuit breaker, by controlling the concave positioning plate 603 to continue to move downward, the gas sucked by the exhaust pipe 605 in the sleeve 6 will be transported into the annular gas storage shell 607 through the gas supply pipe 606, and then the annular gas storage shell 607 will distribute the gas to multiple nozzles 608, and the nozzles 608 will spray the gas onto the surface of the circuit breaker, so as to remove the dust attached to the surface of the circuit breaker and avoid affecting the quality of subsequent coding.

[0028] Example 3:

[0029] Reference Figure 1-Figure 3 The inkjet printer device for a circuit breaker production line is basically the same as that of Example 2, except that: a plurality of heat sinks 701 are fixedly connected to the inkjet printer 7 at equal intervals on the circumference, and the heat sinks 701 are located in the annular gas storage shell 607. Through the arrangement of the heat sinks 701, when the gas in the sleeve 6 is transported into the annular gas storage shell 607 through the gas pipe 606, the flowing gas can carry away the heat absorbed by the heat sink 701 from the inkjet printer 7, thereby playing the role of heat exchange and lowering the operating temperature of the inkjet printer 7, thereby effectively improving the service life of the inkjet printer 7.

[0030] A filter box 8 is fixedly connected to the middle position of the lower end of the lifting plate 4, and a filter plate 801 is threadedly connected to the opening of the filter box 8. The air inlet of the exhaust pipe 605 is connected to the filter box 8. When the sleeve 6 is exhausting air through the exhaust pipe 605, the filter box 8 and the filter plate 801 can filter the gas sucked by the exhaust pipe 605 to prevent dust from entering the sleeve 6 along with the gas, and spraying it onto the surface of the circuit breaker through the nozzle 608, so that some dust is still attached to the surface of the circuit breaker, affecting the adhesion of the inkjet coded characters, effectively ensuring the quality of inkjet coding on the circuit breaker.

[0031] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
