[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1- Figure 5 This utility model provides a technical solution:

[0022] A quick-change mechanism for airtightness testing includes a workbench 1, which is welded together from a base plate, mounting columns, and a top plate to support the quick-change mechanism. Linear guide rails are symmetrically arranged on the top surface of the workbench 1, and slide heads slide along these rails. A sliding plate 8 is mounted on the slide head to limit the movement of the sliding plate 8 and prevent it from shifting, thus facilitating its sliding. A connecting frame is bolted to the workbench 1, and a pen-shaped cylinder 2 is bolted to the connecting frame. The movable end of the pen-shaped cylinder 2 is bolted to the sliding plate 8 to push the sliding plate 8 to move.

[0023] The top surface of the sliding plate 8 is provided with a lower detection assembly and a detection element; the use of the detection element makes it easy to detect whether there is a connector on the lower detection assembly, thereby controlling the operation of the quick-change mechanism for airtightness testing;

[0024] A support 3 is provided on the top surface of the workbench 1, and the support 3 is fixed to the top surface of the workbench 1 by bolts to support the electric push rod 4; the electric push rod 4 is provided on the support 3, and the electric push rod 4 is fixed to the top surface of the support 3 by bolts; the movable end of the electric push rod 4 is fixedly connected to the mounting plate 5, and the bottom of the mounting plate 5 is provided with an upper detection component.

[0025] The upper and lower detection components work together to facilitate the testing of the airtightness of the connector. The operation is simple and convenient, improving the efficiency of connector airtightness testing.

[0026] In this utility model, the upper detection component includes an airtightness test head 10 mounted on the bottom surface of the mounting plate 5, and the airtightness test head 10 is fixed to the middle of the bottom surface of the mounting plate 5 by bolts. The carrier limiting block 2 15 is fixed to the bottom surface of the mounting plate 5 by bolts, and one end of the carrier limiting block 2 15 is engaged with the airtightness test head 10 to limit the airtightness test head 10, thereby improving the stability of the airtightness test head 10 installation. Elastic rods 14 are provided on both sides of the bottom surface of the airtightness test head 10. Since the elastic rods 14 are composed of telescopic rods and springs, they can avoid the phenomenon that the pressure is too large when the electric push rod 4 is pressed down and the connector product is lifted up when it rises, thus facilitating the protection of the connector.

[0027] In this utility model, the lower detection component includes a carrier fixing plate 9 mounted on a sliding plate 8. The top of the carrier fixing plate 9 is provided with a urethane pad 12. The use of the urethane pad 12 effectively ensures the sealing of the connector, thereby facilitating the sealing test of the connector. The top of the urethane pad 12 is provided with a lower test carrier 11 that cooperates with the airtightness test head 10. The sliding plate 8 is symmetrically provided with carrier limiting blocks 13 that cooperate with the carrier fixing plate 9. The carrier limiting blocks 13 are fixed to the sliding plate 8 by bolts and are snapped onto the carrier fixing plate 9 to limit the carrier fixing plate 9, thereby improving the stability of the installation of the lower test carrier 11.

[0028] In this invention, the detection component includes support plates 7 symmetrically arranged at the edges of the sliding plate 8. Each support plate 7 is equipped with a photoelectric sensor 6, which contains a laser emitter, a processor, and a controller. The processor and the laser emitter are electrically connected via wires, and the controller and the pen-shaped cylinder 2 are electrically connected via wires. This is used to detect whether there are connector products on the lower test carrier 11, thereby facilitating automatic detection of connectors. It has a high degree of automation and improves the efficiency of connector detection.

[0029] Working principle: When using this utility model, the connector is first placed on the lower test carrier 11. At this time, the connector will block the light emitted by the photoelectric sensor 6. Then the photoelectric sensor 6 receives the signal and transmits the signal to the processor. The processor controls the pen-shaped cylinder 2 through the controller. The movable end of the pen-shaped cylinder 2 retracts, which drives the sliding plate 8 to move down towards the airtightness test head 10. This, in turn, drives the carrier fixing plate 9 and the lower test carrier 11 to move, thereby moving the connector below the airtightness test head 10.

[0030] Then, open the electric push rod 4, and the mounting plate 5 will move downward by extending the movable end of the electric push rod 4, which in turn will move the air tightness test head 10 downward, so that the air tightness test head 10 and the lower test carrier 11 will be molded together, and then the air tightness test of the connector will be performed.

[0031] After the connector test is completed, each component is reset by controlling the various electrical components.

[0032] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
