Description

Technical Field

[0001] This invention relates to the field of glass processing technology, specifically to a heating device for glass lamination. Background Technology

[0002] Laminated glass is widely used in modern construction and automobile manufacturing due to its safety and sound insulation properties. Heating is a crucial step in the production of laminated glass, aiming to melt the interlayer material at a specific temperature, thereby firmly bonding two or more panes of glass together. However, existing glass lamination heating equipment suffers from several significant problems, limiting its adaptability and heating efficiency in various application scenarios.

[0003] First, existing equipment is often incompatible with glass of different sizes. This means that when processing glass of different sizes, it may be necessary to replace or adjust the equipment, which not only increases production costs but also reduces production efficiency. Furthermore, due to limitations in equipment design, there are also difficulties in the lamination and heating processing of specially shaped or irregularly shaped glass.

[0004] Secondly, existing heating equipment often suffers from uneven heating. For example, some equipment uses direct heating wires or hot air circulation, which, if the heat circulation is not smooth, can easily lead to uneven heating of the glass, incomplete melting of the interlayer, or the formation of air bubbles. This not only affects the quality and performance of laminated glass but may also lead to product scrap and increase production costs.

[0005] Furthermore, existing heating equipment may pose safety hazards after heating is complete. For example, overheating may injure workers, especially during material discharge, where burns can easily occur if operation is difficult. Summary of the Invention

[0006] The purpose of this invention is to provide a heating device for glass lamination to solve the problems mentioned in the background art.

[0007] The technical solution adopted in this invention is as follows:

[0008] A heating device for glass lamination includes: a housing, the housing having a hollow structure, on which two sets of electrode connectors are provided, and multiple external interfaces for vacuuming and connecting to the electrode connectors; a clamping assembly placed inside the housing, the clamping assembly being used for clamping and positioning the laminated glass to be processed, and having a graphene heating film at its bottom; and a lifting assembly located below the housing, the lifting assembly being used to control the lifting of the clamping assembly and simultaneously achieve contact connection between the graphene heating film and the electrode connectors.

[0009] The bottom center of the housing has a through hole adapted to the lifting assembly, the middle of the housing has a U-shaped spatial structure, and two sets of electrode connectors are staggered at two opposite corners of the top center of the housing.

[0010] The lifting assembly includes a lifting seat and a base arranged opposite to each other. Both the lifting seat and the base are groove-shaped structures, and several telescopic rods are arranged between them. The upper and lower ends of the telescopic rods are connected to the lifting seat and the base, respectively.

[0011] The bottom of the base is fixedly mounted on the base plate, and the upper surface of the base plate is connected to the box body at the four corners through fixed connecting posts.

[0012] The clamping assembly has a concave structure with positioning rods at both ends of its two side walls. Two mounting rods are arranged between the two positioning rods, and several telescopic clamps are slidably mounted on the two mounting rods. Both ends of the mounting rods are slidably mounted on the positioning rods through connecting seats.

[0013] The telescopic clamp includes a sliding sleeve fitted onto a positioning rod. An arc-shaped groove is provided on the inner wall of the sliding sleeve. Two guide rods are provided at the bottom of the sliding sleeve. The bottom ends of the guide rods are located inside the clamping block, and springs are provided on the guide rods located between the sliding sleeve and the clamping block.

[0014] The positioning rod includes a rod body, on which a positioning protrusion is provided that matches the arc-shaped groove on the sliding sleeve.

[0015] There are four connectors in total, two of which are located below the two sets of electrode connectors, and the maximum stroke of the connector is less than the length of the electrode connector.

[0016] The connecting seat includes a three-way connecting seat connected to the positioning rod and the mounting rod. A hollow mounting base is fixedly provided at the bottom end of the three-way connecting seat. An abutment is provided inside the mounting base through a return spring. The abutment contacts the graphene heating film provided on the bottom upper surface of the clamping assembly.

[0017] Both the positioning rod and the mounting rod are made of insulating and heat-resistant materials, and the connecting seat is made of metal.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1) By setting a sliding telescopic clamp on the clamping assembly, the present invention can realize the positioning and clamping of laminated glass of different sizes and structures, which significantly improves the applicability;

[0020] 2) This invention uses a contact power supply with a mounting base and electrode connector, and works in conjunction with a graphene heating film to heat the laminated glass to be processed. The graphene heating film can be powered within the stroke of the mounting base, which has high adaptability to the graphene heating film. Furthermore, by optimizing and limiting the position and material of the electrode connector and mounting base, uniform heating of the laminated glass can be achieved.

[0021] 3) This invention uses a clamping assembly to position and clamp the laminated glass to be processed, thereby avoiding direct contact with the glass when the laminated glass is picked up, effectively avoiding the risk of burns to workers and improving safety. Attached Figure Description

Two of the connecting seats 18 are located below the two sets of electrode connectors 8, and the maximum stroke of the connecting seats 18 is less than the length of the electrode connector 8.

[0038] like Figure 8 As shown, the telescopic clamp 16 includes a sliding sleeve 1601 sleeved and mounted on the positioning rod 14. An arc-shaped groove is provided on the inner wall of the sliding sleeve 1601. Two guide rods 1602 are provided at the bottom of the sliding sleeve 1601. Two circular holes adapted to the guide rods 1602 are provided on the clamping block 1603.
