Description

Technical Field

[0001] This utility model relates to the field of capacitor processing technology, and in particular to a spot welding machine oven with a heat-insulating inner liner. Background Technology

[0002] The manufacturing process of capacitors requires steps such as spot welding, bonding, and molding encapsulation. For example, Chinese patent CN105489376A discloses a method for manufacturing a high-reliability electrolytic capacitor, including the following steps: pressing tantalum metal powder into an anode tantalum block and sintering it at high temperature; etching the surface of the anode tantalum block; cleaning the surface of the anode tantalum block with deionized water to remove residual acidic solution, and then drying it in a high-temperature oven; performing electrochemical formation in an electrolyte; cleaning the surface of the anode tantalum block with deionized water to remove residual electrolyte; heat-treating the anode tantalum block in a high-temperature oven; and cooling the anode tantalum block before placing it back into the electrolyte for re-forming treatment.

[0003] Before spot welding, raw materials such as tantalum anode blocks need to be dried at high temperatures using a high-temperature oven. The ovens currently installed in front of the spot welding station have poor insulation, especially around the openable doors, resulting in low drying efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a spot welding machine oven with a heat-insulating inner liner to solve the problem of poor heat insulation effect of ovens in existing spot welding processing lines.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a spot welding machine oven with a heat-insulating inner liner, comprising:

[0006] The enclosure includes an outer shell, an inner shell, and an insulated inner liner, with the insulated inner liner disposed between the outer shell and the inner shell;

[0007] The box door is hinged to the box body;

[0008] The insulation module is detachably installed on the door of the box. The insulation module is filled with an asbestos layer and has waist-shaped holes on opposite sides.

[0009] As a further description of the above technical solution:

[0010] The door is equipped with a positioning pin, which passes through the housing of the insulation module.

[0011] As a further description of the above technical solution:

[0012] The insulation module has a clearance groove on its side wall that corresponds to the waist-shaped hole.

[0013] As a further description of the above technical solution:

[0014] The box body is equipped with a locking seat, and the box door is equipped with a locking rod whose position corresponds to the locking seat. The locking rod is engaged in the locking groove on the locking seat.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the oven body in the spot welding processing line is insulated by an inner heat-insulating liner layer inside the shell, and the oven door is insulated by a detachable heat-insulating module with an asbestos filling layer, which effectively improves the heat insulation effect.

[0017] 2. In this utility model, the metal shell of the heat preservation module is fixed to the door with screws. A waist-shaped hole is provided on one opposite side of the metal shell. After the heat preservation module is disassembled, the metal shell frame is held by the waist-shaped hole, which facilitates the disassembly of the heat preservation module.

[0018] 3. In this utility model, when the box door is closed, the latch rod is engaged in the latch seat, and the length of the latch rod is greater than the width of the latch seat, so that the part of the latch rod that extends beyond the latch seat can serve as a "handle" for opening the box door later.
