[0024] Specifically, Figure 2 and 3 As shown, the automobile lamp 9 in this embodiment is arranged with one side of the automobile lamp inflation port facing upward, and the fixture 2 is arranged corresponding to the contour of the outer side surface of the lower end of the automobile lamp 9, so as to accurately position the automobile lamp 9, and the corresponding plugging head 3 is correspondingly designed to be located above the automobile lamp 9 and moves up and down under the action of the driving device; wherein, the driving device on the plugging head 3 comprises a sealing cylinder 3-1 fixedly connected to the plugging head 3, a lifting plate 3-2 on which the sealing cylinder 3-1 is installed, and a lifting cylinder 3-3 for driving the lifting plate 3-2 to move up and down; when in use, the lifting plate 3-2 and the plugging head 3 are first lowered to a position close to the automobile lamp 9 by the lifting cylinder 3-3, and then the sealing cylinder 3-1 is started, and the plugging head 3 is driven to descend by the sealing cylinder 3-1, so that the plugging head 3 is pressed and sealed outside the automobile inflation port; through the two-stage displacement design, the plugging head 3 can be accurately and stably pressed and sealed outside the automobile lamp inflation port when in use;

[0025] Further, such as Figure 3 and 4As shown, the plugging head 3 in this embodiment includes at least one sealing part 5 connected to an airtight detector 4; wherein the airtight detector 4 can adopt a high-precision differential pressure airtight detector, which is a single-channel positive pressure detector; an air filling channel 6 connected to the airtight detector 4 is provided on the inner side of the sealing part 5; a pipeline connector connected to the air filling channel 6 is provided on the sealing part 5 in this embodiment, and the pipeline connector is connected to a pipeline connected to the airtight detector 4, and the airtight detector 4 is connected to the air filling port of the automobile lamp through the air filling channel 6; when performing airtight detection, the airtight detector 4 inflates the air into the air filling channel 6 through the pipeline, and the gas enters the automobile lamp to be inspected through the air filling channel 6 and the automobile lamp air filling port, and when the airtight detector detects that the air pressure reaches a corresponding size, the gas source is cut off, thereby detecting the change in the air pressure in the automobile lamp 9 within a certain period of time, thereby judging the airtightness of the automobile lamp 9;

[0026] Further, such as Figure 1 As shown, the airtight detector 4 in this embodiment is connected to a controller 7. The controller 7 in this embodiment may be a programmable controller. The controller 7 is used to receive the detection data sent by the airtight detector 4 and form the detection data into a scannable and identifiable code, such as a barcode, a two-dimensional code, etc. The controller 7 is connected to a label printer 8. The label printer 8 prints the identifiable code formed by the controller 7, and then forms a code for each car lamp during detection. The corresponding identifiable code records the airtight detection data of the corresponding car lamp.

[0027] Since there are many types of automobile lamps, in order to enable the airtight detection device in this embodiment to detect a variety of automobile lamps, such as Figure 2 and 3 As shown, the lifting plate 3-2 in this embodiment includes a fixed lifting plate 19 connected to the lifting cylinder 3-3 at the upper end and a movable lifting plate 20 detachably mounted at the lower end of the fixed lifting plate 19 for mounting the sealing cylinder 3-1; and the fixture 2 includes a positioning mounting plate 2-1 mounted on the workbench 1 by a detachable device and a positioning support 2-2 fixedly connected to the positioning mounting plate 2-1 to limit the position of the automobile lamp 9; since the positions of the automobile lamp inflation ports arranged on different automobile lamps are different, and corresponding fixtures of different shapes and structures are required, a detachable movable lifting plate 20 and a positioning mounting plate 2-1 are designed; the structures of different movable lifting plates 20 and positioning mounting plates 2-1 correspond to the structures of automobile lamps one by one. When in use, it is only necessary to select the movable lifting plate 20 with the sealing cylinder 3-1 and the plugging head 3 arranged at the corresponding position and the corresponding positioning mounting plate 2-1 for installation according to the automobile lamp model to be detected;

[0028] Specifically, Figure 2As shown, the detachable device in this embodiment includes a positioning stopper 10 installed on the workbench 1 for limiting the positioning mounting plate 2-1, and a locking device that is driven by a driving device to press and fix the positioning mounting plate 2-1 on the workbench 1; the positioning stopper 10 is arranged in an "L"-shaped structure, and in this embodiment, in order to facilitate the installation of the positioning mounting plate 2-1, the positioning stopper 10 is provided with two respectively located on the left and right sides of the rear end of the positioning mounting plate 2-1, and the positioning mounting plate 2-1 is designed as a square structure. The corresponding limit of the positioning stopper 10 is installed on the right angle outer sides of the left and right sides of the rear end of the square positioning mounting plate 2-1; wherein, the locking device 10 is provided with a locking device 10, and ... The tightening device includes a locking cylinder 17 installed on the workbench 1, and a locking portion 18 located above the positioning mounting plate 2-1 is installed on the piston end of the locking cylinder 17; when installing the positioning mounting plate 2-1, it is only necessary to place the positioning mounting plate 2-1 on the workbench 1 and slide it from front to back, so that the right angles of the rear end of the square positioning mounting plate 2-1 are respectively inserted into the left and right "L"-shaped positioning blocking members 10 for positioning, and then start the locking cylinder 17, and the locking portion 18 is driven to move downward by the locking cylinder 17, so that the locking portion 18 presses the positioning mounting plate 2-1 downward and fixes it on the workbench 1; similarly, the movable lifting plate 20

[0029] In this embodiment, since the sizes of automobile lamps of different models are uniformly distributed, the descending distance of the lifting plate 3-2 is different when performing sealing detection on automobile lamps of different sizes. At the same time, the airtightness detection requirements of different automobile lamps are also different. For example, the pressure to be reached when pressurizing the automobile lamp is different, and the amount of air pressure change allowed within a certain period of time is also different; therefore, the controller 7 in this embodiment is connected to a storage device for storing setting parameters of automobile lamps, and the detection parameters of corresponding automobile lamps are stored in the storage device, so that only the parameters in the storage device need to be called when using, avoiding the need to re-enter the corresponding parameters in the controller 7, and avoiding adverse events caused by employees forgetting;

[0030] At the same time, in order to combine the detection data of the airtight detection equipment with the factory information management system, the controller 7 in this embodiment is connected to the MES equipment of the factory, and the airtight detection data of the corresponding automobile lamps is uploaded through the controller 7, which is convenient for the later statistics and traceability of automobile lamp products.

[0031] like Figure 3 and 4As shown, the airtightness detection equipment in this embodiment also includes a breathable cap installation mechanism arranged above the fixture 2 and pushed by a driving device. The breathable cap installation mechanism is located above the breathable cap installation position of the automobile lamp.

A receiving cavity 13 for placing the breathable cap 22 is opened on the inner side of the lower end of the pressing piece 12; the breathable cap 22 is interference-fitted with the receiving cavity 13, so that the breathable cap 22 is clamped and limited in the receiving cavity 13; on the lifting plate When 3-2 descends to a position close to the automobile lamp 9, the plugging head 3 moves downward under the action of the sealing cylinder 3-1 to plug the automobile air filling port on the automobile lamp 9 and perform an air tightness test on the automobile lamp. After the test is completed, the sealing cylinder 3-1 drives the plugging head 3 to retract, and then the installation cylinder 11 drives the pressing piece 12 to move downward, thereby pressing and clamping the air cap 22 in the pressing piece 12 to the installation position outside the automobile lamp. After the clamping installation is completed, the air cap 22 is limited by the automobile lamp 9 due to the clamping, thereby making the air cap 22 fall out of the accommodating cavity 13;

[0032] like Figure 4 As shown, at this time, the pressing piece 12 presses the breathable cap 22 downward and clamps it on the connection position on the outside of the car lamp; in order to avoid missing the installation of the breathable cap 22, the upper end of the accommodating cavity 13 in this embodiment is provided with a detection sensor 14 installed on the inner side of the pressing piece 12 for detecting whether the breathable cap 22 is placed in the accommodating cavity 13; wherein the detection sensor 14 can be an infrared sensor.

[0033] like Figure 1 and 3 As shown, in order to improve the moving accuracy of the lifting plate 3-2, a guide device is provided on the lifting plate 3-2 in this embodiment, and the guide device includes a guide rod 15 installed on the workbench 1 and a guide sleeve 16 installed on the fixed lifting plate 19 and slidably connected to the outside of the guide rod 15. In this embodiment, a fixed mounting plate 21 is fixedly connected to the upper end of the guide rod 15, and the lifting cylinder 3-3 is fixedly installed on the upper end of the fixed mounting plate 21. The piston end of the lifting cylinder 3-3 passes through the fixed mounting plate 21 and is fixedly connected to the lifting plate 3-2.
