Description

Technical Field

[0001] The utility model belongs to the technical field of mica sheet winding equipment, and in particular relates to a terminal resistance wire contact welding mechanism. Background Art

[0002] Toasters and bread machines are one of the commonly used household appliances in living and office environments. They usually use electric heating plates to heat and bake food. Conventional electric heating plates are generally composed of mica sheets and resistor flat wires wound on the mica sheets. The resistor flat wires are generally wound on the mica sheets by a winding machine to complete the processing. Before the mica sheets are wound with the resistor flat wires and after the mica sheets are finished with the resistor flat wires, the resistor flat wires need to be welded to the terminal blocks of the mica sheets.

[0003] At present, the conventional welding of resistor flat wires to the terminals on the mica sheet is completed by manual operation. Specifically, before winding the resistor flat wire on the mica sheet, the resistor flat wire is first pulled out from the resistor flat wire raw material and one end thereof is welded to one of the terminals of the mica sheet. After the mica sheet completes the winding of the resistor flat wire, the resistor flat wire between the resistor flat wire raw material and the mica sheet is cut off and the other end thereof is welded to another terminal of the mica sheet. The problem is that the operator needs to repeat the above operation to complete the welding process of the terminal of the mica sheet and the resistor flat wire. The labor intensity of the operator during the operation is high. As the working time increases, the operating efficiency of the operator continues to decrease, affecting the processing efficiency of the product. In addition, it is difficult to accurately weld the resistor flat wire to the terminal of the mica sheet by manual welding. For example, the welding position of the resistor flat wire is offset, and there is welding leakage and desoldering between the resistor flat wire and the terminal of the mica sheet, which affects the processing quality of the product.

[0004] Therefore, further improvements are needed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0034] See also Figure 1-9The terminal resistance wire contact welding mechanism is arranged on the mica sheet winding equipment, which includes a welding mounting seat 5, a first electrode device 1, a second electrode device 2, a wire clamping device 3, a first moving device 6, and a second moving device 7. The welding mounting seat 5 can be movably mounted on the working platform 4 through the first moving device 6. The working platform 4 is preferably a frame of the equipment. The first moving device 6 is located between the welding mounting seat 5 and the working platform 4 and enables the terminal resistance wire contact welding mechanism to move in the up and down directions. The first electrode device 1 can be movably mounted on the welding mounting seat 5 through the second moving device 7 and is used to install the positive electrode head. The second moving device 7 is located between the first electrode device 1 and the welding mounting seat 5 and enables the first electrode device 1 to move in a direction close to or away from the second electrode device 2. The second electrode device 2 is fixedly mounted on the welding mounting seat 5 and is used to install the negative electrode head. The wire clamping device 3 is fixedly mounted on the welding mounting seat 5 and is used to move the terminal resistance wire contact welding The mechanism clamps the resistor flat wire and conveys the resistor flat wire to the welding position of the terminal resistor wire touching welding mechanism. Specifically, when the resistor flat wire is conveyed to the outside of the terminal resistor wire touching welding mechanism, the first moving device 6 pushes the terminal resistor wire touching welding mechanism to move upward. After the wire clamping device 3 clamps the resistor flat wire, the first moving device 6 pushes the terminal resistor wire touching welding mechanism to move downward and pulls the resistor flat wire downward to the welding position of the terminal resistor wire touching welding mechanism. The second moving device 7 pushes the first electrode device 1 close to the second electrode device 2 and welds the resistor flat wire to the terminal of the mica sheet. The terminal resistor wire touching welding mechanism can automatically complete the positioning of the resistor flat wire on the terminal resistor wire touching welding mechanism and the welding of the resistor flat wire and the terminal of the mica sheet without manual operation by the operator, thereby reducing the labor intensity of the operator. The terminal resistor wire touching welding mechanism can maintain a relatively stable processing efficiency, thereby ensuring the processing efficiency of the product.

[0035] In addition, through the terminal resistance wire contact welding mechanism of the above technical solution, it is possible to accurately position the resistance flat wire to the welding position of the terminal resistance wire contact welding mechanism, thereby reducing the error rate during the welding of the resistance flat wire and ensuring the processing quality of the product.

[0036] Furthermore, the first moving device 6 includes a first movable plate 601, a first screw rod 602, and a first drive motor 603.

When the first drive motor 603 rotates reversely, the first screw rod 602 rotates reversely and drives the first movable plate 601 to move downward, so that the terminal resistance wire welding mechanism moves downward, and the first electrode device 1, the second electrode device 2, and the wire clamping device 3 move downward. Those skilled in the art can understand it.

[0037] Furthermore, the first moving device 6 also includes a limiting structure.

The second metal sensor 403 is electrically connected to the control device of the terminal resistance wire contact welding mechanism and is fixed on the working platform 4 through a fastening component. When the terminal resistance wire contact welding mechanism moves upward, the second metal sensor 403 detects the second metal sheet 605 and sends a signal to the control device of the terminal resistance wire contact welding mechanism, so that the first drive motor 603 stops working and prevents the terminal resistance wire contact welding mechanism from continuing to move upward.

When the movable end of the second movable cylinder 702 retracts relative to its fixed end, the first electrode device 1 moves in a direction away from the second electrode device 2, so that the first electrode device 1 and the second electrode device 2 are separated from each other and the welding operation of the terminal of the resistor flat wire and the mica sheet is completed. Those skilled in the art can understand this.

[0041] Furthermore, the second movable device 7 also includes a first guide structure. Specifically, in this embodiment, the first guide structure includes a first guide column 503 and a first guide sleeve 703.
