Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 4 As shown, the transformer bottom shell feeding mechanism of this embodiment includes a positioning fixture 1, an automatic clamp 2 and a clamp driving arm 3, the positioning fixture 1 includes two symmetrically arranged positioning clamps 101, the bottom of the positioning clamps 101 is connected to a clamp driving 102, a storage seat 4 is arranged between the two positioning clamps 101, the automatic clamp 2 is correspondingly arranged above the positioning clamp 1, the clamp driving arm 3 includes a transverse platform 301 and a lifting drive 302, the lifting drive 302 is vertically installed downward on the transverse platform 301, and the automatic clamp 2 is installed at the bottom of the lifting drive 302.

[0031] In actual use, the transformer bottom shell 8 placed on the storage seat 4 first enters the positioning fixture 1, and the two positioning jaws 101 start to clamp and fix the transformer bottom shell 8.

[0032] Then the automatic clamping jaw 2 at the bottom of the lifting drive 302 descends and clamps the transformer bottom shell 8, and the two positioning clamping jaws 101 are released.

[0033] The next step is that the automatic gripper 2 rises and the transverse platform 301 moves forward.

[0034] Finally, the automatic gripper 2 descends and releases, and the transformer bottom shell 8 is placed in the empty base fixture 7. The base fixture 7 with the transformer bottom shell 8 placed is transported forward, and the automatic gripper 2 is reset to the top of the positioning fixture 1 so as to cycle the loading of the next transformer bottom shell 8.

[0035] The end of the positioning fixture 1 is provided with a proximity sensor 5, and the proximity sensor 5 is electrically connected to the clamping jaw drive 102. The proximity sensor 5 can be a photoelectric sensor commonly used in the market, and the clamping jaw drive 102 can be a clamping jaw motor commonly used in the market, so that after sensing that the transformer bottom shell 8 enters the positioning fixture 1, the clamping jaw drive 102 is started, and the transformer bottom shell 8 is clamped by the positioning clamp 101, and the positioning process is automatically completed.

[0036] The middle part of the inner side of the positioning clamp 101 is provided with a clearance groove 103, and the upper part of the clearance groove 103 is provided with a bottom shell inner recess 104. The clearance groove 103 can avoid the position interference between the positioning clamp 101 and the storage seat 4 passing through the middle. The bottom shell inner recess 104 can further improve the positioning stability when the positioning clamp 101 clamps the transformer bottom shell 8.

[0037] A guide slot 401 is provided in the middle of the storage seat 4, and the input end of the guide slot 401 is connected to a feeding module (not shown in the figure). The guide slot 401 can limit the position of the transformer bottom shell 8 to further improve the positioning accuracy. The feeding module can adopt a commonly used feeding vibration plate on the market to automatically feed the transformer bottom shell 8 and transport the transformer bottom shell 8 one by one to the positioning fixture 1.

[0038] The inner sides of the left and right ends of the automatic clamping jaws 2 are both provided with concave clamping sleeves 201. The concave clamping sleeves 201 are used to clamp the transformer bottom shell 8 to improve the positioning stability.

[0039] The positioning jaws 101 are arranged on the front and rear sides of the storage seat 4, the automatic jaws 2 are arranged on the left and right sides of the storage seat 4, and the bottom of the concave clamping sleeve 201 protrudes downward. Since the automatic clamping jaw 2 needs to clamp the transformer bottom shell 8 while the positioning jaws 101 clamps the transformer bottom shell 8, the positioning jaws 101 and the automatic clamping jaw 2 are arranged in separate directions and the bottom of the concave clamping sleeve 201 protrudes downward, which can effectively avoid collision and interference between the positioning fixture 1 and the automatic clamping jaw 2, and ensure that the automatic clamping jaw 2 can smoothly grab the transformer bottom shell 8.

[0040] The traverse platform 301 is connected to the linear screw slide 303 by driving, and the front and rear ends of the linear screw slide 303 are provided with positioning sensor modules, and the positioning sensor modules are electrically connected to the linear screw slide 303. The positioning sensor module includes a groove-type photoelectric sensor 601 and a trigger plate 602, and the groove-type photoelectric sensor 601 is arranged at the front and rear ends of the linear screw slide 303, and the trigger plate 602 is fixedly connected to the side of the traverse platform 301. The groove-type photoelectric sensor 601 and the trigger plate 602 can effectively improve the movement accuracy of the traverse platform 301, and ensure that the automatic gripper 2 can be accurately placed in the base fixture 7 at the other end after grabbing the transformer bottom shell 8 at one end of the storage seat 4.

[0041] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
