Description

Technical Field

[0001] This utility model relates to the field of test dotting technology, and in particular to a test double-sided dotting device. Background Technology

[0002] The connectors of the drying heater products need to be marked on both sides. In practice, the marks are first made on both sides of the connector, and then the resistance value is tested, or the marks are made after the test is completed. However, there are instances where marks are missed or the resistance is not tested after marking. Moreover, the current operation usually separates the testing and marking, which affects efficiency and increases the workload of the staff. Therefore, a double-sided marking device is needed. Utility Model Content

[0003] The purpose of this invention is to provide a testing device for double-sided dotting, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a testing device for double-sided marking, comprising a base, an installation box fixedly mounted on the upper surface of the base, a cover plate fixedly mounted on the upper surface of the installation box, a marking mechanism disposed inside the installation box, a fixing seat fixedly mounted inside the installation box, a male test terminal fixedly mounted on the upper surface of the fixing seat, a low-voltage control box fixedly mounted on the upper surface of the base, a box cover fixedly mounted on the upper surface of the low-voltage control box, and a testing mechanism disposed inside the low-voltage control box.

[0005] Preferably, a male connector for connecting the testing instrument is fixedly installed on the testing mechanism, and a cooling fan is fixedly installed inside the low-voltage control box.

[0006] Preferably, the marking mechanism includes a cylinder fixedly installed in the mounting box, a connecting block fixedly installed at the output end of the cylinder, a cylinder chuck fixedly installed at the other end of the connecting block, and a marker pen snapped into the cylinder chuck.

[0007] Preferably, the testing mechanism includes an integrated circuit board fixedly installed inside a low-voltage control box, a low-resistance converter fixedly installed on the integrated circuit board, a first intermediate relay fixedly installed on the integrated circuit board, a solenoid valve fixedly installed on the integrated circuit board, the other end of the solenoid valve fixedly installed on a cylinder, and a good product indicator light fixedly installed on the integrated circuit board.

[0008] Preferably, a second intermediate relay is fixedly mounted on the integrated circuit board, and a defective indicator light is fixedly mounted on the low-resistance converter.

[0009] Preferably, a power switch is fixedly mounted on the integrated circuit board, a power indicator light is fixedly mounted on the integrated circuit board, a 240V to 24V power supply is fixedly mounted on the integrated circuit board, and a debugging display screen is fixedly mounted on the low resistance converter.

[0010] The beneficial effects of this utility model are:

[0011] In this invention, the marking mechanism allows the cylinder to move the markers, and the two sets of markers to push forward. The markers then make contact with the heater female plug to mark the points, which facilitates marking the female plug of the drying heater and prevents the phenomenon of missing markings or missing resistance tests after marking.

[0012] In this invention, the testing mechanism can be designed to test whether a product is good. When a product is determined to be good, the solenoid valve will open the air valve and drive the marker pen to mark the female connector of the drying heater. If the resistance value is not within the range, the defective product indicator light will light up and the marker pen will stop moving. This design allows testing and marking to be performed simultaneously, improving efficiency and reducing the workload of staff. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example:

[0020] like Figure 1-4 As shown, this embodiment provides a testing device for double-sided dotting, including a base 1, an installation box 2 fixedly installed on the upper surface of the base 1, a cover plate 3 fixedly installed on the upper surface of the installation box 2, a dotting mechanism 4 provided inside the installation box 2, a fixing seat 5 fixedly installed inside the installation box 2, a male test terminal 6 fixedly installed on the upper surface of the fixing seat 5, a low-voltage control box 7 fixedly installed on the upper surface of the base 1, a box cover 8 fixedly installed on the upper surface of the low-voltage control box 7, a testing mechanism 9 provided inside the low-voltage control box 7, a male connector 10 for connecting a testing instrument fixedly installed on the testing mechanism 9, and a cooling fan 11 fixedly installed inside the low-voltage control box 7.

[0021] In this embodiment of the utility model, specifically, the dotting mechanism 4 includes a cylinder 41 fixedly installed in the mounting box 2, a connecting block 42 fixedly installed at the output end of the cylinder 41, a cylinder chuck 43 fixedly installed at the other end of the connecting block 42, and a marker pen 44 snapped into the cylinder chuck 43.

[0022] To facilitate marking and reduce the occurrence of missed markings or missed resistance tests after marking, cylinder 41 moves connecting block 42, which in turn moves cylinder clamp 43, which in turn moves marker pen 44. The two sets of marker pens 44 are pushed forward and make contact with the heater female plug to mark the points. This makes it easy to mark the female plug of the drying heater and prevents missed markings or missed resistance tests during the testing process.

[0023] In this embodiment of the utility model, specifically, the testing mechanism 9 includes an integrated circuit board 91 fixedly installed inside the low-voltage control box 7, a low-resistance converter 92 fixedly installed on the integrated circuit board 91, a first intermediate relay 93 fixedly installed on the integrated circuit board 91, a solenoid valve 94 fixedly installed on the integrated circuit board 91, the other end of the solenoid valve 94 fixedly installed on the cylinder 41, a good product indicator light 95 fixedly installed on the integrated circuit board 91, a second intermediate relay 96 fixedly installed on the integrated circuit board 91, a defective product indicator light 97 fixedly installed on the low-resistance converter 92, a power switch 98 fixedly installed on the integrated circuit board 91, a power indicator light 99 fixedly installed on the integrated circuit board 91, a 220V to 24V power supply 910 fixedly installed on the integrated circuit board 91, and a debugging display screen 911 fixedly installed on the low-resistance converter 92.

[0024] To enable simultaneous testing and marking, the female connector of the drying heater to be tested is inserted into the male connector test terminal 6. The test result is transmitted to the low-voltage control box 7. When the low-resistance converter 92 receives the low-frequency signal value, it makes a judgment based on the resistance value and conversion time preset on the control and debugging display screen 911. If the product is judged to be good, the low-resistance converter 92 outputs the converted voltage to the first intermediate relay 93. The first intermediate relay 93 then sends a command to the solenoid valve 94 and the good product indicator 95. The solenoid valve 94 opens the air valve, causing the marker pen 44 to mark the female connector of the drying heater. If the resistance value is not within the range, the low-resistance converter 92 outputs the converted voltage to the second intermediate relay 96. The second intermediate relay 96 then sends a command to the defective product indicator 97, which lights up, and the marker pen 44 stops moving.

[0025] Working principle: In use, first insert the male connector 10 of the testing instrument into the socket, then turn the power switch 98 to start the device; the power indicator light 99 will light up. Next, insert the female connector of the drying heater to be tested into the male connector test terminal 6. The low-resistance testing instrument measures the resistance value of the heater and transmits the test result to the low-voltage control box 7. When the low-resistance converter 92 receives the low-frequency signal value, it judges the resistance value and conversion time preset on the control and debugging display screen 911. If it is judged to be a good product, the low-resistance converter 92 outputs the converted voltage to the first intermediate relay 93, which then sends a command to the solenoid valve 94 and the good product indicator light 95. When the indicator light illuminates, the solenoid valve 94 opens the gas valve, and gas is transmitted to the cylinder 41. The cylinder 41 drives the connecting block 42 to move, which in turn drives the cylinder chuck 43 to move. The cylinder chuck 43 then drives the marker pen 44 to move, pushing both sets of marker pens 44 forward. The marker pens 44 then make contact with the heater female plug and mark a point. If the resistance value is outside the range, the low-resistance converter 92 outputs the converted voltage to the second intermediate relay 96, which then sends a command to the defective product indicator light 97. The defective product indicator light 97 will then illuminate, and the marker pen 44 will stop moving. In this way, defective products can be effectively guaranteed to flow out without increasing the process and time.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
