Description

Technical Field

[0001] The invention relates to the field of heat shrink tube heating, in particular to a micro heat shrink tube heating machine capable of controlling automatic opening and closing of a heating plate and automatic delivery of a wire. Background Art

[0002] Heat shrink tubing: Heat shrink tubing is a special polyolefin heat shrink tubing, also known as EVA material. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer has the characteristics of insulation, corrosion resistance, and wear resistance, while the inner layer has the advantages of low melting point, waterproof sealing, and high adhesion.

[0003] Because different wire harnesses will be welded during the wiring harness assembly process, the copper core at the welding point will be exposed. In order to protect this part, it is necessary to add a heat shrink tube and perform heat shrink treatment on this part.

[0004] The heat shrink tube heating machines currently on the market are all offline due to their large size and cannot be used on assembly lines. Existing heat shrink tube heating machines use synchronous belts or chains, so they require a large space. Summary of the invention

[0005] The purpose of the present invention is to solve the defect that the existing heat shrink tube heating machine cannot work on the assembly line due to its large size, and to provide a miniature heat shrink tube heating machine.

[0006] In order to achieve the above objectives, the following technical solutions are provided:

[0007] The micro heat shrink tube heating machine includes a cylinder, a telescopic rod of the cylinder fixed on a connecting block, the connecting block is inserted into a hole of a connecting plate, the connecting plate is fixed on a slider, and the slider is installed on a slide rail. A connecting rod is fixed on the upper part of the connecting plate, and the upper end of the connecting rod passes through the crossbeam of the mounting plate. The first side plate and the second side plate of the mounting plate are fixed at both ends of the crossbeam. The first side plate and the second side plate are both hinged with rollers through angle irons, and the rollers slide in a limited position through a limiting track. The first side plate and the second side plate have the same structure, including a long hole opened in the middle, a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod are hinged at the same hinge point at the ends of the first side plate and the second side plate. The other end of the first connecting rod is fixed on the upper heating plate of the heating device, and the other end of the second connecting rod is fixed on the lower heating plate of the heating device. The upper heating plate and the lower heating plate are connected to a fixed shaft through a bearing, and the protruding end of the fixed shaft is placed in the long hole of the first side plate and the second side plate.

[0008] Preferably, it also includes a first fixing plate and a second fixing plate placed on the outside of the mounting plate, the first fixing plate and the second fixing plate have the same structure and are provided with long holes, a wiring harness clamp and a guide wheel are fixed on the front end of the first side plate and the second side plate, the wiring harness clamp extends out of the outside of the first fixing plate and the second fixing plate, the guide wheel slides in the long holes of the first fixing plate and the second fixing plate, and the limiting rail is fixed on the inside of the first fixing plate and the second fixing plate.

[0009] The beneficial effects are:

[0010] 1Through this structure, the size of the device is minimized while achieving the heating action. During heating, the heating plate wraps the outside of the heat shrink tube to reduce air circulation and make the heating temperature stable and uniform.

[0011] 2. This application uses a cylinder as the power source and works in a single heating mode to reduce the overall size of the equipment and enable use on an assembly line.

[0012] 3. Fully enclosed heating is adopted to make the heating effect more uniform and the heat shrinking effect better. Because the heating plate adopts two semicircular structures, a cylindrical heating chamber is formed during heating to prevent the influence of air circulation on heat, so that the outside of the heat shrink tube is evenly heated, thus making the heating effect better.
