The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , an aspect of the embodiment of the present specification discloses an insulation packaging and testing device for a transformer, including: a workbench 100 provided with a support frame 110 ; a conveyor belt 200 set on the workbench 100 for The transformer 900 to be packaged and tested is transported; the packaging mechanism 300 is installed on the workbench 100 for encapsulating the transformer 900 with the insulating tape 312; the turning mechanism 400 is installed on the workbench 100 and used for packaging the transformer 900 900 is turned over so that the pins of the transformer 900 are vertically facing downward; the testing mechanism 500 is set on the workbench 100 for testing the transformer 900; the placing box 800 is set on one side of the workbench 100 for storing insulation The transformer 900 after packaging and testing; the lateral movement mechanism 600 is installed on the support frame 110; the longitudinal movement mechanism 700 is installed on the lateral movement mechanism 600; wherein, the longitudinal movement mechanism 700 is provided with 4 pneumatically evenly distributed horizontal The adjacent spacing between the clamps 711 and the four pneumatic clamps 711 is consistent with the adjacent spacing between the conveyor belt 200 , the packaging mechanism 300 , the turning mechanism 400 , the testing mechanism 500 and the placing box 800 ; The transformer 900 can be moved laterally from the conveyor belt 200 to the packaging mechanism 300 , the turning mechanism 400 , the testing mechanism 500 and the placing box 800 in sequence by the driving of the placing and lateral moving mechanism 600 .

It should be understood that the working process is as follows:

At the beginning, first the conveyor belt 200 transports the transformer 900 to the clamping position of the pneumatic clamp 711; then the lateral movement mechanism 600 moves the pneumatic clamp 711 to the top of the transformer 900 on the conveyor belt 200 (as shown in FIG. 1, it moves to the right), The longitudinal movement mechanism 700 drives the pneumatic clamp 711 to move down, so that the clamping block of the pneumatic clamp 711 is located on the side of the transformer 900, and then the pneumatic clamp 711 can clamp the transformer 900. "setting" and the setting of four pneumatic clamps 711, the four pneumatic clamps 711 are to clamp the transformer 900 on the conveyor belt 200, the packaging mechanism 300, the turning mechanism 400 and the testing mechanism 500 respectively and simultaneously; The clamp 711 moves up, and the lateral movement mechanism 600 drives the pneumatic clamp 711 to move left, so that the transformer 900 on the conveyor belt 200 moves to the packaging mechanism 300 , and the transformer 900 on the packaging mechanism 300 moves to the flip mechanism 400 and the transformer 900 on the flip mechanism 400 The transformer 900 moved to the test mechanism 500 and the test mechanism 500 is moved to the placement box 800, and then the longitudinal moving mechanism 700 moves the pneumatic clamp 711 down, and the pneumatic clamp 711 can release the transformer 900 to complete the movement of the transformer 900; Before or during the next movement of the 900, the conveyor belt 200 will transport the next transformer 900 to the gripping position of the pneumatic clamp 711, the packaging mechanism 300 will insulate and package the transformer 900 moved this time, and the turning mechanism 400 will The moving transformer 900 is turned over, and the testing mechanism 500 will test the moving transformer 900, so that the pneumatic clamp 711 can pick up the transformer 900 during the next movement; thus, semi-automatic or automatic insulation packaging and testing can be realized to meet the requirements of gradual automation. production needs.

It can be understood that the setting of the flip mechanism 400 is because the pins of the transformer 900 need to be located on the side during insulation packaging, and cannot face up or down, otherwise the packaging will not be completed, and during the test, the pins of the transformer 900 are required. The transformer 900 after insulation and encapsulation needs to be turned upside down by the turning mechanism 400, so that the pins of the transformer 900 are changed from being located on the side to the bottom side, and the pins of the transformer 900 are facing vertically downward, which is convenient for the testing mechanism 500 to perform tests on the transformer 900. test.

For another example: since the multiple transformers 900 on the conveyor belt 200 are conveyed next to each other, the transformers 900 cannot be clamped laterally, so the pneumatic clamps 711 for clamping the transformers 900 on the conveyor belt 200 should be clamped from the front and the rear. Transformer 900, and the other three pneumatic clamps 711 clamp the transformer 900 from left and right, as shown in FIG. 1; other settings only need to be reasoned according to conventional logic on the basis of realizing the above working process.
