Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a moving contact welding device. Background Art

[0002] The moving contact is the contact that moves during power operation. The moving contact consists of a contact piece and a contact point welded to the contact piece.

[0003] Traditional moving contact welding processing mostly adopts manual operation, that is, the contact piece is first placed on the conveyor belt, the paste dispensing machine applies solder paste on both ends of the contact piece, and then the contact is placed at the position coated with solder paste, and finally the welding equipment is started for welding, and the finished product is manually checked to see if it meets the quality inspection requirements, and the good products are placed in the receiving frame to be transported away. This method obviously reduces the efficiency of moving contact welding because the contact piece feeding is manually placed. To this end, the applicant provides a welding device that can realize automatic feeding of contacts to improve the efficiency of moving contact welding. Utility Model Content

[0004] The utility model aims to provide a moving contact welding device, to provide a welding device capable of automatically feeding materials, so as to improve the moving contact welding efficiency.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A moving contact welding device comprises a frame, the frame is provided with a conveyor belt, and also comprises a feeding assembly, a paste dispensing machine and a welding device which are arranged in sequence in the conveying direction of the conveyor belt, the feeding assembly comprises a transmission plate fixedly connected to the conveyor belt and a feeding box fixedly arranged to the frame, the bottom of the feeding box is provided with an opening facing the transmission plate, the feeding box is fixedly provided with a first cylinder and a second cylinder from top to bottom in sequence, the first cylinder drives a dividing sheet located in the feeding box, and the second cylinder drives a supporting sheet located at the opening.

[0007] The working principle and beneficial effects of the utility model:

[0008] This solution puts multiple contacts neatly into the feed box after overlapping them up and down. At this time, the dividing sheet is located outside the feed box, and the support sheet is located at the opening at the bottom of the feed box. The support sheet supports multiple contacts upward, and then the first cylinder is started to drive the dividing sheet to extend into the feed box to separate the bottom contact. The conveyor belt rotates and drives the conveyor plate to move to the bottom of the opening. The second cylinder drives the support sheet to retract, and the bottom contact loses support and falls onto the conveyor plate. Then the second cylinder drives the support sheet to move into the feed box, and the second cylinder drives the dividing sheet to move outside the feed box. Multiple contacts lose support from the dividing sheet and fall onto the support sheet. Repeating the above operation can realize automatic feeding. The conveyor plate transfers the contacts to the paste dispensing machine, and the paste dispensing machine applies solder paste to both ends of the contacts. Then, contacts are manually placed at the position coated with solder paste, and finally, they are transferred to the welding equipment for welding.

[0009] This solution can realize automatic feeding through the cooperation of the feeding assembly and the conveyor belt, and can improve the welding efficiency of the moving contact compared with the manual feeding in the prior art.

[0010] Furthermore, the transmission plate is also fixed with a motor, and the motor drives a pressing plate for pressing the contact piece. When the contact piece falls from the feed box to the transmission plate, the motor drives the pressing plate to rotate and press the contact piece on the transmission plate, thereby facilitating subsequent welding work.

[0011] Furthermore, the number of the feed boxes is multiple, and the welding efficiency of the moving contact can be improved by feeding materials through multiple feed boxes at the same time.

[0012] Furthermore, the number of the material dividing sheets and the supporting sheets are both 2, and both are symmetrically arranged along the axis of the feed box. This optimization scheme can improve the supporting effect of the supporting sheets and the material dividing sheets.

[0013] Furthermore, a material receiving frame is provided at the bottom of the frame, and the welded moving contacts are collected by the material receiving frame.

[0014] Furthermore, the pressing plate is specifically a rubber plate, which is soft and convenient for pressing the contact piece tightly without causing indentations on the surface of the contact piece. BRIEF DESCRIPTION OF THE DRAWINGS

In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0022] Embodiment: A moving contact welding device, such as Figure 1 and Figure 2 As shown, it includes a frame 2, the frame 2 is symmetrically rotatably connected with a transmission roller 4, and a transmission belt 6 is wound between the transmission rollers 4 on both sides.
