Description

Technical Field

[0001] This utility model belongs to the technical field of extrusion tooling for residual glue in large barrels for sealed solar modules, specifically relating to an extrusion tooling for residual glue in large barrels for sealed solar modules. Background Technology

[0002] The sealing-type solar module residual glue extrusion fixture is a piece of equipment used in the field of photovoltaic module technology. Taking a common extrusion fixture as an example, it typically includes a frame, a drive roller, a squeeze roller, a traction roller, and a gap adjustment component. The drive roller, squeeze roller, and traction roller are all rotatably mounted on the frame. The drive roller and squeeze roller are arranged adjacent to each other with a squeezing gap between them. The gap adjustment component can adjust this gap distance. The squeeze roller is driven by the drive roller, and the traction roller is driven by either the drive roller or the squeeze roller. There is a space below the frame for holding the glue bucket. The opening of the aluminum foil bag inside the glue bucket passes through the squeezing gap from bottom to top and then wraps around to the traction roller. This fixture has a simple and reliable structure and ingenious design, which can realize automated residual glue discharge. It effectively solves the problems of difficulty in manually removing the aluminum foil bag with residual glue from the large glue bucket, difficulty in manually squeezing out the residual glue after removal, and incomplete discharge of residual glue. It has the advantages of convenient operation, saving time and labor, high efficiency, and low cost, and can significantly increase production capacity.

[0003] A photovoltaic (PV) module typically consists of glass, encapsulant film, solar cells, interconnect strips, busbars, backsheet, frame, junction box, and silicone sealant. The primary function of silicone sealant is bonding and fixing, adhering the frame to the PV laminate to seal and protect the PV module. It is also used for bonding and fixing the junction box. Specialized sealant for solar PV modules is stored in large aluminum bags and is extracted and injected using dispensing equipment to bond and seal the frame to the PV module and the junction box. However, the sealant at the bottom of the bag is often difficult to remove, leaving residue. Conventional methods for extruding residual sealant involve manual extrusion, which is time-consuming, labor-intensive, inefficient, and prone to incomplete removal of residual sealant. Common residual sealant extrusion fixtures are open-type, making it impossible to avoid safety risks during the extrusion process, resulting in a low safety factor. Utility Model Content

[0004] The purpose of this invention is to provide a sealing-type adhesive residue extrusion tool for large drums of solar modules, to solve the problems mentioned in the background art. A typical photovoltaic module structure includes glass, adhesive film, solar cells, interconnect strips, busbars, backsheet, frame, junction box, and silicone sealant. The main function of the silicone sealant is bonding and fixing, adhering the frame and photovoltaic laminate to achieve sealing and protection of the photovoltaic module. It is also used for bonding and fixing the junction box. Solar photovoltaic module sealant is stored in aluminum bags in large drums and is extracted and injected using a dispensing device to bond and seal the frame and photovoltaic module, and to bond the junction box. However, the sealant at the bottom of the drum is usually difficult to extract, leaving residue. Conventional residual adhesive extrusion methods involve manual extrusion, which is time-consuming, labor-intensive, inefficient, and prone to incomplete extrusion. Common residual adhesive extrusion tools are open-type, making it impossible to avoid safety risks during the extrusion process, resulting in a low safety factor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing solar module residual glue extrusion tool, comprising a main body, a control panel installed at the left end of the main body, a sliding groove provided on the inner side of the main body, two sliding glass doors installed on the inner side of the main body via the sliding groove, a sealing strip installed at the rear end of the frontmost sliding glass door, a rubber plug fixed at one end face of the sliding glass door, rubber plates provided on the left and right sides inside the main body, multiple insertion holes distributed at the front end of the rubber plates, a working chamber provided inside the main body, an extrusion roller installed at the upper position inside the working chamber, a fixed roller installed at the middle position inside the working chamber, a residual glue bag installed below the fixed roller, and multiple glue buckets placed inside the working chamber.

[0006] Preferably, the main body is equipped with casters at the four lower corners, allowing the main body to move.

[0007] Preferably, the front end of the main body is provided with sensing devices located at the lower left and right sides, and the two sensing devices correspond to the two sliding glass doors.

[0008] Preferably, the sliding glass door can move laterally within the sliding groove, and the two sliding glass doors slide to the sides respectively, so that the main body is in a closed state.

[0009] Preferably, the sliding glass door can be moved to allow the rubber plug to be inserted into the insertion hole, while the rubber plate is in close contact with the sliding glass door.

[0010] Preferably, the control panel is installed on the side end face of the main body, and multiple control buttons are provided at the front end of the control panel.

[0011] Preferably, three extrusion rollers are provided inside the working chamber, and the extrusion rollers are located above the fixed rollers.

[0012] Preferably, the glue bucket is located below the residual glue bag.

[0013] Compared with the prior art, this utility model provides a sealed solar module residual glue extrusion tooling for large drums, which has the following beneficial effects:

[0014] 1. The enclosed large-bucket glue residue extrusion fixture includes a closed structure, three extrusion devices, a control panel, sensors, and rollers. The inner compartment of the extrusion fixture is used to hold the glue bucket. The fixture as a whole has a box-like structure. The top and one side of the fixture are sliding glass doors, while the other three sides are fixed glass and aluminum alloy frames. The extrusion device includes a squeezing roller and a fixed roller. The residue bag is fixed on the fixed roller. The squeezing roller moves from top to bottom to perform the extrusion action. The control panel includes a master control key, movement keys for the squeezing rollers of the three extrusion devices, and control keys for the squeezing rollers. The key is used to control the horizontal position and extrusion action of the extrusion roller. The sensor is installed on the sliding glass door fixture and one side to identify whether the sliding door is closed. The entire extrusion process must be in a closed state. If extrusion is started in an open state, a warning will be issued and the extrusion will not be able to start. If the sliding door is opened during the extrusion process, the extrusion action will be forcibly stopped and a warning will be issued. The wheels are used to move the extrusion fixture. They are locked during the extrusion process and unlocked when movement is needed. The fixture can be pushed. In addition, when not in operation, the fixture can be used as a storage platform.

[0015] 2. To reduce the impact force between the sliding glass door and the inner wall of the main body when sliding, this device has a rubber plate installed on the inner wall of the main body. When the sliding glass door is closed, the rubber plate absorbs the impact force, and at the same time, the rubber plug in the sliding glass door is inserted into the insertion hole to increase the stability of the sliding glass door when it is closed.
