[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. When the number of an element is referred to as "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0024] like Figure 1-3 As shown, in this embodiment, a transformer face cover pressing mechanism is provided, including a fixed plate 17, on which a storage platform 16 and a transport pressing mechanism are fixedly provided, and a conveying mechanism is also installed on the fixed plate 17, and the conveying mechanism includes a lifting and moving assembly and a guide frame 8. In order to stabilize the position of the transformer housing on the guide frame 8 when the housing is pressed against the face cover, a limiting door 9 is coaxially installed on the guide frame 8, and an automatic clamp 10 for clamping the transformer housing is fixedly provided on the rear side of the limiting door 9. The automatic clamp 10 on the limiting door 9 can clamp the housing and limit the position of the transformer housing on the guide frame 8.

[0025] In this embodiment, the traditional assembly line is eliminated because the rigidity of the assembly line is insufficient and the reaction force provided is small and it cannot cooperate with the transport and pressing mechanism to effectively press the cover and the shell together, and the limit door 9 will move with the assembly line and cannot play a limiting role. A placement guide groove 12 for placing the mutual inductor is provided in the middle of the guide frame 8. A long through groove is provided in the middle of the guide frame 8, and a pair of abutment bars extending toward the middle of the guide frame 8 are provided on the groove wall. Therefore, the pair of abutment bars and the through groove form the above-mentioned placement guide groove 12. The lifting and moving assembly includes an abutting cross column 20, the width of which is smaller than the placement guide groove 12, so as to penetrate the guide groove and abut the mutual inductor. The lifting and moving assembly also includes a second screw guide rail 19, and a lifting cylinder 18 is fixedly provided at the output end (sliding end) of the second screw guide rail 19. The output end of the lifting cylinder 18 is fixedly connected to the abutting cross column 20, and the lifting cylinder 18 can control the movement of the abutting cross column 20 and the second screw guide rail 19 in the vertical direction.

[0026] In summary, the process of transferring the transformer housing by the conveying mechanism is further described. After the transformer housing is placed at one end of the guide frame 8 by equipment or manually, the transformer housing is now in limited abutment with the abutment bar of the storage guide groove 12. When the transformer needs to be transported, the abutment cross column 20 will be lifted by the lifting cylinder 18. The lifting height of the abutment cross column 20 is higher than the abutment bar, so the abutment cross column 20 will lift the transformer housing, and the transformer housing is not abutted with the abutment bar but placed on the abutment cross column 20. Then, the abutment cross column 20 with the transformer housing placed thereon will move under the control of the second screw guide rail 19, and then the transformer housing will be moved. When the transformer housing reaches a specific position, the lifting cylinder 18 controls the abutment cross column 20 to descend to the bottom of a pair of abutment bars, so the transformer housing will re-abut against the abutment bar, thereby completing the movement of the transformer housing. When the cover needs to be pressed and closed, the abutting crossbar will push up again, and cooperate with the carrying and pressing mechanism to press the housing and the cover together. When closing, the abutting crossbar does not push up completely like when carrying, but pushes up a part and just pushes the transformer housing away from the guide frame 8.

[0027] In this embodiment, the transport and pressing mechanism includes a stand 4, a transverse plate 5, a horizontal moving device and a lifting drive device 7. The transverse plate 5 is slidably connected to the stand 4. The horizontal moving device is installed on one side of the stand 4 to control the movement of the transverse plate 5 relative to the stand 4. The lifting drive device 7 is installed on the transverse plate 5. The output end of the lifting drive device 7 is equipped with a negative pressure suction cup 6 and a glue dispensing component (not marked in the figure). The glue dispensing component is located on one side of the negative pressure suction cup. The glue dispensing component is installed on the transverse plate 5 like the negative pressure suction cup 6. The glue dispensing component includes a driving member and a glue dispensing head. The driving member can optionally use a cylinder. The driving member causes the glue dispensing head to move downward so that the bottom end of the glue dispensing head can dispense glue into the shell. After the pressing surface cover, the cover and the shell can be reliably connected together.

[0028] When it is necessary to press the surface cover onto the transformer housing, the lifting drive device 7 will control the negative pressure suction cup 6 to move downward to adsorb the surface cover to be adsorbed placed on the storage table 16, and the storage table 16 can be connected to the output end of the vibration plate to achieve the purpose of automatically covering the surface; then the lifting drive device 7 controls the negative pressure suction cup 6 with the surface cover adsorbed to lift upward, and then the horizontal moving device controls the horizontal movement of the transverse plate 5, that is, controls the translation of the negative pressure suction cup 6 with the surface cover. When the lifting drive device 7 moves into place, the negative pressure suction cup 6 (with the surface cover adsorbed) connected to it will be located above the transformer housing, and finally the lifting drive device 7 will control the negative pressure suction cup 6 to move downward, and cooperate with the raised abutting horizontal column 20 to complete the covering of the transformer housing and the surface cover.

[0029] Specifically, the horizontal moving device includes a first motor 1, a first screw rod 3 and a pair of bearing seats 14 fixedly arranged on the vertical frame 4. A screw nut 15 threadedly connected to the first screw rod 3 is fixedly arranged on one side of the transverse plate 5. The first screw rod 3 is rotatably connected to the vertical frame 4 through a pair of bearing seats 14. The output end of the first motor 1 and one end of the first screw rod 3 are both covered and meshed with a belt 2. The first motor 1 is transmission-connected to the first screw rod 3 through the belt 2. The rotation of the first screw rod 3 will control the horizontal movement of the screw nut 15, so the first screw rod 3 can control the movement of the transverse plate 5.

[0030] Specifically, the lifting drive device 7 is a first screw slide rail, and a downward extending pressure plate is fixedly provided at the output end of the first screw slide rail. The added pressure plate can extend the defect that the output end of the first screw 3 cannot extend downward. The negative pressure suction cup 6 is fixedly provided at the bottom end of the pressure plate. Therefore, after the first screw slide rail is started, the pressure plate can be controlled to move downward or upward, and the fixed negative pressure suction cup 6 can also complete the upward or downward movement.

[0031] In this embodiment, the limiting door 9 is located above the object guide groove 12, and a through opening corresponding to the object guide groove 12 is provided at the bottom of the limiting door 9. When the transformer housing is transported, the transformer housing can be moved through the through opening.

[0032] The automatic clamp 10 is a clamping cylinder, and a pair of contoured clips 11 are fixedly provided at the output end of the clamping cylinder. The clamping cylinder is fixedly connected to the limit door 9, and the output end of the clamping cylinder is vertically downward. The gap of the contoured clip 11 is arranged on the upper surface of the guide frame 8. In other words, the contoured clip 11 is arranged in a position close to the upper surface of the guide frame 8, so that the contoured clip 11 can directly clamp the transformer housing.

[0033] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
