Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component laminating equipment, in particular to a transmission crossbeam mechanism used in a photovoltaic component laminating machine. Background Art

[0002] In the production of photovoltaic modules, the laminator is a key packaging equipment, and the photovoltaic modules are transmitted by the photovoltaic module transmission mechanism. The existing photovoltaic module transmission mechanism includes a chain transmission mechanism, a high-temperature cloth and a transmission beam mechanism. Multiple high-temperature cloths are connected to form a closed loop through the transmission beam mechanism. The two ends of the transmission beam mechanism are fixedly connected to the transmission chains on the corresponding sides. The photovoltaic modules are placed on the high-temperature cloth, and the transmission chains at both ends of the transmission beam mechanism pull the transmission beam mechanism to operate. The transmission beam drags the high-temperature cloth to move, thereby transmitting the modules. The high-temperature cloth is usually a thinner polytetrafluoroethylene glass cloth, which is easy to wear during use and needs to be replaced regularly, that is, the high-temperature cloth needs to be disassembled from the transmission beam. During the transmission process, in order to prevent the connecting parts between the high-temperature cloth and the transmission beam from falling off, the connecting parts need to be fixed to the transmission beam. Figure 1 As shown, it is the conventional structure of the transmission beam mechanism, including a clamping plate A, a clamping rib plate B, a connecting shaft C and a beam body D. The clamping rib plate B is welded to one side of the long side of the beam body D, and its bent part forms a groove with the side of the beam body D, which is used to place the connecting shaft C. The connecting shaft C is used to connect with the rod sleeve at one end of the high-temperature cloth. The clamping plate A is fixed to the other side of the long side of the beam body, and its bent part can just press the connecting shaft C to fix it. When disassembling and assembling, all the clamping plates A on the transmission beam must be removed before the high-temperature cloth can be replaced, which is time-consuming and labor-intensive, and it is very inconvenient to disassemble. In addition, there is a risk that the screws and latches will fall into the laminator cavity, causing losses. How to have a quick way to disassemble and assemble is a technology that is urgently needed in this industry. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0027] like Figure 2-Figure 7 As shown, the transmission crossbeam mechanism of the present invention adopts the following structure, including a crossbeam assembly 1, a connecting rod shaft 2, and a clamping spring 4. Figure 4 and 5 As shown, the crossbeam assembly 1 includes a crossbeam body 101, a baffle 103 and a connecting rod bearing support device, preferably a connecting end 102 is provided, and the connecting end 102 is respectively fixedly provided at both ends of the crossbeam body 101, and is used to connect the crossbeam assembly with the chain, and the baffle 103 is provided at one end of the side of the crossbeam body 101, and is vertically provided with the crossbeam body, and is used to block the connecting rod shaft 2 and prevent it from moving along the length direction of the crossbeam body, and the connecting rod bearing support device includes a plurality of bending plates, each of which includes two mutually perpendicular bending plates. The edge portion is provided, and a plurality of bending plates are provided on the side portion of the beam body along the length direction of the beam body. One end of the bending plate is fixedly connected to the beam body, and the other end is extended and bent along the side portion of the beam body to form a bending edge 1041. The bending edge 1041 and the side surface of the beam body have a receiving space for receiving the connecting rod shaft to form a receiving groove for receiving the connecting rod shaft. The connecting rod shaft 2 is located in the receiving groove formed by the bending edge and the side surface of the beam body, one end is limited by the baffle 103, and is supported by the bending edge in the length direction. The gap formed between the bending edges is used to accommodate the high-temperature cloth sleeves arranged at intervals at the ends of the high-temperature cloth. Notches are provided on at least two of the bending edges so that the bending edges form bending edges 1042 with notches. Clamping springs 4 are respectively provided in the notches. One end of the clamping spring 4 is fixedly connected to the beam body, and the other end is a free end arranged in the same direction as the bending edge, so as to clamp the connecting rod shaft into the clamping spring. The clamping spring can be a clamping ring, and it is best to adopt the following structure, such as Figure 6 As shown, the clamping spring 4 includes an arc clamping section 402 and a connecting section 401 tangent to the arc clamping section. The arc clamping section is used to support and accommodate the clamping connecting rod shaft. Usually, the diameter of the arc clamping section is slightly larger than the diameter of the connecting rod shaft, generally 0.1-0.3mm larger. The position of the arc clamping section 402 tangent to the connecting section 301 is located at a semicircular arc. The arc of the arc clamping section is larger than the semicircular arc. In this way, after the beam body is connected through the connecting section, the arc clamping section surrounds The portion of the connecting rod shaft can be greater than 180 degrees and can surround most of the connecting rod shaft, thereby clamping the connecting rod shaft more firmly. In order to facilitate the installation of the connecting rod shaft and increase the clamping strength of the entire clamping spring, a bevel 403 is provided at the free end of the arc clamping section, and the bevel 403 is bent outward of the arc of the arc clamping section, and is preferably arranged perpendicular to the cross-section of the intersection of the two. This can better prevent the connecting rod shaft from detaching from the clamping spring when the high-temperature cloth is pulled, thereby further increasing the clamping strength of the arc clamping section.

[0028] The connecting rod bearing support device preferably adopts the following structure, which is a clamping bent plate 104, the clamping bent plate 104 includes a bottom plate 1043 and a bent edge 1041 bent upward from the edge of the bottom plate, the bent edge 1041 is a right-angle bend on the bottom plate 1043, the bent edges are arranged at intervals, and the intervals of the bent edges are used to accommodate the high-temperature cloth sleeves arranged at intervals at the ends of the high-temperature cloth, and the bent edges and the side of the beam body 101 form a receiving groove for accommodating the connecting rod shaft, which is used to place the connecting rod shaft 2. Notches are set on at least two of the bent edges to form a notched bent edge 1042, and the clamping spring is located at the notched bent edge. The clamping bent plate is fixedly connected to the beam body through its bottom plate, and the clamping spring is fixedly connected to the bottom plate through its connecting section to achieve fixed connection with the beam body. The connecting rod bearing support device adopting this structure can support and fix the connecting rod shaft on the one hand, and on the other hand, because the bottom plate and the bent edge are fixedly connected as a whole, the horizontal load-bearing capacity of the entire transmission beam mechanism is improved, and the assembly and manufacture of the entire transmission beam are facilitated.

[0029] Depending on the use of the transmission crossbeam mechanism, when the connecting rod shaft is only provided on one side of the crossbeam assembly, the connecting rod bearing support device can be provided on only one side of the crossbeam assembly surface; when the connecting rod shaft is provided on both sides of the crossbeam assembly, the connecting rod bearing support device is provided on both sides of the crossbeam assembly surface. The crossbeam body is generally made of a rectangular square tube.

[0030] During installation, the high temperature cloth is connected to the crossbeam assembly 1 through the connecting rod shaft 2. Figure 3 As shown, first pass the connecting rod shaft 2 through the high temperature cloth sleeves arranged at intervals at the ends of the high temperature cloth 3. The part of the connecting rod shaft 2 outside the high temperature cloth sleeve corresponds to the position of the receiving grooves on both sides of the beam assembly 1, and is pressed into the clamping springs 4 installed in the middle of the grooves on both sides of the beam assembly 1. The connecting rod shaft is supported by the bending plate and clamped by the clamping springs and firmly locked by the clamping springs, and the high temperature cloth 3 can be connected and installed on the beam assembly; when removing the high temperature cloth 3, just pull the connecting rod shaft 2 out from between the free end of the clamping spring 4 and the beam body. When installing on the transmission chain, fix the two ends of the beam assembly 1 on two synchronously moving chains. With the transmission crossbeam mechanism of the utility model structure, when replacing the high-temperature cloth, it is only necessary to put the high-temperature cloth on the connecting rod shaft through the high-temperature cloth sleeve arranged at the end thereof, and then press the connecting rod shaft into the clamping spring. The clamping spring clamps the connecting rod shaft, and the bending plate supports and limits the connecting rod shaft horizontally. Therefore, it can be installed very conveniently. When removing the high-temperature cloth, it is only necessary to lift the connecting rod shaft upward from the clamping end of the clamping spring. Disassembly and assembly are very convenient, and there is no need to disassemble and assemble bolts, which saves time and effort.

[0031] The high-temperature cloth of the laminating machine of the utility model structure can be set individually or multiple high-temperature cloths can be connected end to end through a transmission beam mechanism. When the transmission beam is connected end to end, clamping springs, bending plates and connecting rod shafts are arranged on both sides of the beam body of the transmission beam.
