[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] In the battery piece manufacturing process, there are several stations that need to implement light and / or heating treatment on the battery piece in the furnace cavity. The industry usually uses a steel mesh belt or a roller as a conveying mechanism to convey the battery piece. When the light or heating assembly (usually an infrared lamp or an LED light source module) is arranged in the lower furnace cavity, the steel mesh belt or the roller will form a large area of shielding to the lower surface of the battery piece, reducing the light or heating effect.

[0034] In view of this, the present application provides a transmission net chain, as shown in Figure 1 The transmission net chain includes two parallel chains 2 and a plurality of transmission supports 1. The two ends of the transmission support 1 are connected to the two chains 2, respectively. The transmission support 1 includes a set of support rods 11 extending along a first horizontal direction and at least one pair of support frames arranged on the support rods 11. The set of support rods 11 includes two support rods 11. The pair of support frames has inclined surfaces arranged opposite to each other. The inclined surfaces of the pair of support frames are used to carry a battery piece together.

[0035] By arranging the transmission support 1 including two support rods 11 and at least one pair of support frames, the shielding can be effectively reduced, avoiding the reduction of the light or heating effect caused by the shielding, improving the process treatment effect and the product quality. Since the shielding is small, the weight of the transmission support 1 is small, reducing the load of the chain 2 driving mechanism. At the same time, since the shielding is small, the heat absorption of the transmission support 1 is reduced, thereby reducing the heat taken out of the furnace by the transmission support 1, and finally reducing the production cost.

[0036] To reduce the contact between the battery piece and the transmission net chain, as shown in Figures 2-3 In one transmission support 1, the two support frames in each pair of support frames are symmetrically arranged. The support frame includes a vertical section 121 and an inclined section 122. The vertical section 121 extends along the vertical direction. The inclined section 122 extends along a direction with a predetermined angle with the horizontal plane. The predetermined angle can be selected from 15° to 60°, for example, 15°, 20°, 26°, 31°, etc. The top ends of the vertical section 121 and the inclined section 122 are connected. The bottom ends of the vertical section 121 and the inclined section 122 are arranged on the support rod 11. As can be seen, when the support frame is used to carry the battery piece, the edge of the battery piece only contacts at least one inclined section 122, and the contact area is small.

[0037] Considering that the battery piece may move due to the movement of the chain 2 when being conveyed, continuing to refer to Figures 2-3 The top end of the inclined section 122 forms an arc-shaped section 123. The top end of the vertical section 121 is connected to the arc-shaped section 123. The arc-shaped section 123 constitutes a limiting structure for the edge of the battery piece, preventing the battery piece from deflecting during conveying due to various reasons.

[0038] In long-term use, if the two bottom ends of the support frame are arranged on the same support rod 11, the frame body of the support frame will be bent and inclined in the opposite direction of the conveying direction of the chain 2 due to the load of the battery piece, that is, deformation occurs. Figure 2 For each transmission bracket 1, the bottom ends of the inclined sections 122 of the same pair of support frames are arranged on one of the corresponding two support rods 11, and the bottom ends of the vertical sections 121 of the same pair of support frames are arranged on the other of the corresponding two support rods 11. In this way, the two bottom ends of the support frame are arranged in front of and behind each other, which obviously has a certain anti-deformation ability and greatly improves the durability; at the same time, it also provides connection for the middle parts of the two support rods 11, thereby strengthening the overall strength.

[0039] For various process purposes, the battery piece may need to be carried on shaft sleeves of different materials. Optionally, one of a ceramic shaft sleeve, a silica gel shaft sleeve, and a Teflon shaft sleeve is installed on the inclined section 122 to achieve the corresponding process purpose. Ceramic material has the advantages of high hardness, wear resistance, high temperature resistance, and not easy to deform due to high temperature, etc.; silica gel and Teflon are relatively soft and not easy to scratch the battery piece.

[0040] For ease of production and processing, the support rod 11 and the support frame can be selected to have a circular cross section as the main structure, that is, the cross sections of the support rod 11 and the support frame are circular. At the same time, considering the high-temperature working environment, the material of the support rod 11 and the support frame needs to be selected from a high-temperature resistant material, such as one or a combination of two or more of ceramic, ceramic composite material, stainless steel, Teflon, carbon fiber composite material, and high-molecular polymer material, or other high-temperature resistant materials.

[0041] For example, Figure 2 In order to maintain a fixed distance, the transmission bracket 1 further includes a first connecting piece 13 and a second connecting piece 14. The first ends of the two support rods 11 of the same group are fixedly connected to the first connecting piece 13, and the second ends of the two support rods 11 of the same group are fixedly connected to the second connecting piece 14. The first connecting piece 13 and the second connecting piece 14 are respectively installed on two parallel chains 2. Through the above arrangement, not only the distance between the two support rods 11 is fixed, but also the structure of the transmission bracket 1 becomes an integral whole, which is convenient for disassembly, assembly and maintenance.

[0042] Further, referring to Figure 1 and Figure 2The transmission chain further comprises a pair of threaded mounting plates 15, which are arranged at corresponding positions on the inner sides of the two chains 2. The first connecting plate 13 is provided with a circular hole, and the second connecting plate 14 is provided with a waist-shaped hole, the short axis diameter of which is the same as the diameter of the circular hole. The waist-shaped hole extends along the first horizontal direction. The first connecting plate 13 and the second connecting plate 14 are fixed to the corresponding mounting plates 15 by screws, respectively. The threaded holes can be blind holes or through holes. If the threaded holes are blind holes, long screws can be selected to pass through the first connecting plate 13 or the second connecting plate 14 and be fixed to the mounting plates 15, leaving a little space for the first connecting plate 13 or the second connecting plate 14 to move vertically. If the threaded holes are through holes, the screws can pass through the first connecting plate 13 or the second connecting plate 14 and be fixed to the mounting plates 15, so that the first connecting plate 13 and the second connecting plate 14 are tightly connected to the corresponding mounting plates 15. Of course, the threaded holes of one mounting plate 15 can be blind holes, and the threaded holes of the other mounting plate 15 can be through holes. For example, the threaded holes of the mounting plate 15 corresponding to the first connecting plate 13 are through holes, and the threaded holes of the mounting plate 15 corresponding to the second connecting plate 13 are blind holes. In this way, the first connecting plate 13 is tightly fixed to the corresponding mounting plate 15 by the screw, and the movement in the vertical direction and the horizontal direction is limited. The second connecting plate 14 is fixed to the corresponding mounting plate 15 by the screw, and when the chain spacing changes slightly, the screw in the waist-shaped hole of the mounting plate 15 connected to the second connecting plate 14 will move slightly.

[0043] To save the process, the two support rods 11, the first connecting plate 13 and the second connecting plate 14 of the same group can be integrally formed when the transmission support 1 is produced. Alternatively, for the purpose of saving cost, the first end and the second end of the two support rods 11 of the same group are fixed to the upper surface or the lower surface of the first connecting plate 13 and the second connecting plate 14 by welding, respectively.

[0044] In the existing heating furnace, there is a transmission mechanism for simultaneously conveying two parallel battery sheets. Accordingly, the transmission support 1 can comprise two support rods 11 and two pairs of support frames, which are arranged on the support rods 11 of the transmission support 1 along the first horizontal direction. The two pairs of support frames respectively carry one battery sheet, and finally achieve the purpose of carrying and conveying two parallel battery sheets.
