Description

Technical Field

[0001] The utility model relates to the technical field of transmission structures for sintering furnaces, in particular to a chain rod type transmission structure with an integrally formed carrying frame. Background Art

[0002] Solar cells are photovoltaic semiconductor thin-film components that use sunlight to generate electricity directly. During their manufacturing process, sintering operations are required. In a chain-rod sintering furnace, solar cells are placed on a carrier with a support structure. Driven by the transmission chains on both sides of the carrier, the solar cells are driven to run in a sintering furnace with a heating device, thereby achieving sintering of the solar cells.

[0003] The utility model patent with application number CN202320822135.0 involves a chain transmission bracket, which mainly includes a metal strip and a thimble. Based on the structural design of the thimble, it is generally fixed to the metal strip by welding. The disadvantage caused by this is that when the thimble is welded to the metal strip, it is not only time-consuming and labor-intensive, and the processing efficiency is low, but the welding process will cause the frame to deform, affecting the stability of solar cell transmission.

[0004] At the same time, there are further defects in the prior art:

Under the high temperature environment in the furnace and the vibration and friction caused by the long-term contact between the ejector pin and the solar cell, the ejector pin is easily corroded by the solar cell itself and the slurry and other chemical substances attached to the solar cell. The corroded ejector pin will also pollute the solar cell.

[0006] Second, since the solar cell is partially mounted on the ejector pin, and the thermal conductivity of the ejector pin is relatively high, the heat conduction effect of the ejector pin will cause uneven temperature at the contact point between the solar cell and the ejector pin, affecting the uniformity of the solar cell sintering.

[0053] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0054] like Figure 1 As shown, a chain-rod transmission structure with an integrally formed carrier frame includes a transmission assembly 1 and a plurality of carrier frames 2. The transmission assembly 1 includes a power source 11, a transmission wheel 12, and two sets of symmetrically arranged transmission chains 13; the length direction of each carrier frame 2 is perpendicular to the movement direction, and the two ends of the carrier frame 2 are respectively fixed to the two sets of transmission chains 13.

[0055] Specific, combined Figure 2-Figure 5 As shown, the mounting frame 2 includes a frame body 21 and a bracket 22 which are integrally formed by sheet metal by laser cutting, wire cutting or stamping, and at least a part of the structure of the bracket 22 is formed by bending, and the bracket 22 is used to carry the solar cell. Figure 2 , Figure 3 As shown, the frame 21 can be bent into a C-type and an n-type. In this case, the bracket 22 is bent at its root to be vertical. A plurality of brackets 22 are used to support the solar cells. Figure 4 , Figure 5 As shown, the frame 21 can also be bent into a U-shape and an L-shape, in which case the bracket 22 is bent together with a part of the structure of the frame 21 and is vertical. Of course, in other embodiments, the cross section of the frame 21 perpendicular to the length direction can also be configured into other shapes. The frame 21 and the bracket 22 are integrally formed, which is easy to form and will not deform in long-term use, effectively ensuring the stability of solar cell transmission.

[0056] It should be noted that the brackets 22 formed on the frame 21 can be a pair or multiple pairs, the number is not limited, and can be selected according to the actual application scenario.

[0057] In application scenarios, such as Figure 6As shown, the two ends of the frame 21 along the length direction are respectively provided with curved sealing plates 3, and the ends of the curved sealing plates 3 on several frames 21 in the horizontal movement direction are arranged close to each other. Since the carrier 2 is applied to the sintering furnace, the two ends of the frame 21 need to extend outward from the furnace body and be connected to the transmission device, so a chamber for the frame 21 to move needs to be provided on the furnace wall. The existence of the chamber will inevitably cause gas convection inside and outside the furnace body, so the gas convection can be blocked by providing the curved sealing plates 3.

[0058] In one embodiment, if Figure 6 , Figure 7 As shown, the curved sealing plate 3 is constructed in a sheet-like structure and extends upward from the frame 21. Of course, the curved sealing plate 3 extending downward can also be installed in the reverse direction.

[0059] In other embodiments, Figure 8 As shown, the curved sealing plate 3 is constructed in a sheet-like U-shaped structure. The arranged and distributed curved sealing plates 3 can achieve the barrier of the chamber formed at the opposite side furnace wall, and isolate the gas convection inside and outside the sintering furnace.

[0060] The bracket 22 has a support surface 220, and the support surface 220 is directly used to carry solar cells, or a support member 223 for carrying solar cells is configured at the support surface 220. The support member 223 can be made of temperature-resistant and / or wear-resistant and / or corrosion-resistant materials such as ceramics, glass, and quartz glass.

[0061] In a first embodiment, if Fig. 9 As shown, the bracket 22 is provided with a groove 221, which can be directly formed when the bracket 21 and the bracket 22 are integrally formed, and then based on the existence of the groove 221, a guide rod 222 is formed for the tubular support member 223 to be inserted and matched. The bracket 22 is also formed with a first stopper 224a, which is arranged on the side of the guide rod 222 away from the root of the groove 221; Fig.10 As shown, after the first stopper 224a is deformed by the external force, a notch 225 is formed between the first stopper 224a and the guide rod 222 for the support member 223 to be inserted into the guide rod 222, and after the insertion and insertion are completed, the first stopper 224a is reset by applying a reverse force. In the use scenario, the gap between the end of the guide rod 222 and the first stopper 224a can be hidden in the support member 223.

[0062] In a second embodiment, if Fig.11 As shown, one end of the guide rod 222 away from the root of the groove body 221 is bent to form a second limiter 224b. When the tubular support member 223 is inserted into the guide rod 222, the second limiter 224b can be formed by bending to prevent the support member 223 from falling off.

[0063] In a third embodiment, if Fig.12As shown, the bracket 22 is formed with a third stopper 224c and a fourth stopper 224d distributed at both ends of the support surface 220. The support member 223 is C-shaped along a cross section perpendicular to the length direction and is buckled on the support surface 220. The third stopper 224c and the fourth stopper 224d stop both ends of the support member 223. When the support member 223 is assembled, in the initial state, as shown in FIG. Fig.13 As shown, the fourth limiting member 224d is upright. After the supporting member 223 is buckled onto the supporting surface 220, the supporting member 223 is limited by bending the fourth limiting member 224d.

[0067] In one embodiment, if Fig.14 As shown, the first transmission part 112 and the second transmission part 113 both adopt a combination of a synchronous wheel and a synchronous chain.

[0068] In another embodiment, Fig.15 As shown, the first transmission part 112 adopts a pair of meshing bevel gears, and the second transmission part 113 adopts a combination of a synchronous wheel and a synchronous chain.

[0072] At this time, the power source 11 is constructed as a single power drive, including a driving part 111 , the driving part 111 adopts a motor, and the output end adopts a third transmission part 114 to be transmission-connected with the transmission shaft 14 .

[0073] In other embodiments, the driving portion 111 may also be directly connected to the transmission shaft 14 .

[0074] Example 3

[0075] like Fig.17 As shown, the power source 11 is constructed as a dual-power drive, including two sets of driving parts 111. The driving parts 111 use motors and are directly connected to any driving wheels 12 surrounded by the corresponding side transmission chain 13.

[0076] like Fig.18 As shown, in other embodiments, the driving unit 111 is connected to the transmission wheel 12 by a fourth transmission unit 115 .

[0077] In combination with the above-mentioned embodiment 1 and embodiment 3, the final output end of the power source 11 is connected to the corresponding side transmission wheel 12 respectively, so that the power can be evenly transmitted to the transmission wheels 12 on both sides, and the problem of unbalanced transmission of the transmission chains 13 on both sides can be avoided during long-term application.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
