Description

Technical Field

[0001] The utility model relates to the field of drying devices, in particular to a conveying chain and a battery tunnel furnace. Background Art

[0002] Based on the rapid development of solar cells, cost control and capacity improvement are the key to whether solar cells can be profitable, and the cleaning and drying time of the cells is an important factor affecting the capacity and cost. After the cells are cleaned by texturing, the baskets containing silicon wafers need to be taken out of the cleaning tank and enter the subsequent drying process. During the drying process, the baskets are transported by the conveyor chain. Since the baskets containing silicon wafers will drip after being taken out of the cleaning tank, water will accumulate on the contact surface between the conveyor chain and the baskets, affecting the drying effect of the cells and the baskets, and thus affecting the capacity of the entire set of equipment. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the utility model is to provide a conveyor chain, which reduces the accumulation of water on the contact surface between the conveyor chain and the flower basket by setting a guide groove, thereby improving the drying effect of the battery cells and the flower basket.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a conveying chain, including multiple conveying components, two adjacent conveying components are connected by a shaft pin, and the conveying component includes a support member, the support member is used to support the conveyed workpiece, and the support member is provided with a guide groove. Through the guide groove provided on the support member, the accumulated water in the flower basket falls on the support member and flows into the bottom of the backflow groove, ensuring that there is no water accumulation on the contact surface of the conveyed workpiece and the conveying component, thereby improving the drying effect of the tunnel furnace.

[0005] Furthermore, the groove wall of the guide groove is inclined, and the guide groove is a "V"-shaped structure. The inclined groove wall is used for liquid drainage, and the liquid flows along the inclined groove wall to the bottom of the guide groove. Since the guide groove is a "V"-shaped structure, the bottom area is small, which is conducive to the accumulation of water at the bottom flowing out of the guide groove.

[0006] Furthermore, the guide groove includes a first guide groove, and the first guide groove divides the support member into two symmetrically arranged support parts.

[0007] Furthermore, the support portion is an isosceles trapezoidal structure that is narrow at the top and wide at the bottom.

[0008] Furthermore, the guide groove includes a second guide groove, the support member includes an inclined second side surface, and the two second side surfaces of two adjacent transmission components constitute the second guide groove.

[0009] Furthermore, a limiting member is arranged on the side of the supporting member close to the conveyed workpiece, and a plurality of the limiting members are arranged, which are respectively located on both sides of the conveying direction of the conveying chain.

[0010] Furthermore, the conveying assembly includes a first connecting member and a second connecting member, the first connecting member and the second connecting member are arranged at two ends of the transmission direction of the transmission chain, and two adjacent conveying assemblies are connected by the first connecting member and the second connecting member.

[0011] Furthermore, the first connecting member is provided with a first connecting hole, the second connecting member is provided with a second connecting hole, and an axle pin passes through the first connecting hole and the second connecting hole to connect the first connecting member and the second connecting member.

[0012] Furthermore, the first connecting member, the second connecting member and the supporting member are integrally connected.

[0013] A battery tunnel furnace comprises the conveying chain as described above.

[0014] The beneficial effects of the utility model are:

[0015] 1) By setting a guide groove on the support, the accumulated water in the flower basket falls on the support and flows into the bottom of the guide groove, ensuring that there is no water on the contact surface between the conveying workpiece and the conveying component, thereby improving the drying effect of the tunnel furnace.

[0016] 2) The groove wall of the guide groove is inclined, and the inclined groove wall is used for liquid drainage. The liquid flows along the inclined groove wall to the bottom of the guide groove. By setting the guide groove as a "V"-shaped structure, the bottom area is small, which is conducive to the accumulation of water at the bottom flowing out of the guide groove.

[0017] 3) By arranging a limiter on the support, the flower basket can be prevented from being separated from the conveying chain during the transmission process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0028] See attached Figure 1-2 As shown, a battery tunnel furnace in this embodiment is used to heat and dry batteries. The tunnel furnace includes a conveyor chain, which is driven by a gear 8 to convey the workpiece, and the workpiece is conveyed from the inlet of the tunnel furnace to the tunnel furnace. After the workpiece is dried, the workpiece is conveyed from the tunnel furnace to the outlet. In this embodiment, the workpiece conveyed by the conveyor chain is a battery, which is contained in a basket 9.

[0029] The conveyor chain includes a plurality of conveyor components 1, and two adjacent conveyor components 1 are connected by axle pins. During the production process, the bottom rod of the flower basket 9 is seriously stained with liquid. When the flower basket 9 is placed on the conveyor component 1 for transmission, liquid still drips, causing the liquid to drip onto the conveyor component 1. Water accumulates on the contact surface between the flower basket 9 and the conveyor component 1, affecting the drying effect of the tunnel furnace.

[0030] The conveying assembly 1 disclosed in the present application is provided with a guide groove 3, and the liquid will flow along the groove wall of the guide groove 3 to the bottom of the guide groove 3, ensuring that there is no water accumulation on the contact surface between the flower basket 9 and the conveying assembly 1, thereby improving the drying effect of the tunnel furnace. The accumulated water that flows to the bottom of the guide groove 3 can be converged to the outside of the tunnel furnace through the liquid confluence device.

[0031] In some embodiments, the guide groove 3 is a strip structure, and the direction of the guide groove 3 is perpendicular to the transmission direction of the conveying chain, so that the liquid is guided through the guide groove 3 and flows down from both sides of the transmission chain.

[0032] See attached Figure 3-4 As shown, in some embodiments, the conveying assembly 1 includes a support member 2, and the support member 2 is used to support the flower basket 9. The guide groove 3 includes a first guide groove 31. The first guide groove 31 is arranged on the contact surface between the support member 2 and the flower basket 9. The first guide groove 31 divides the support member 2 into two symmetrically arranged support parts, and the support parts are used to support the flower basket 9. The groove wall of the first guide groove 31 is arranged obliquely, and the first guide groove 31 is similar to a "V"-shaped structure. On the one hand, the inclined groove wall is used for liquid drainage, and the liquid flows along the inclined groove wall to the bottom of the first guide groove 31; on the other hand, the groove wall of the first guide groove 31 is arranged obliquely, so that the support part forms a structure with a wide bottom and a narrow top. The narrow upper part is used to support the flower basket 9. The narrow upper setting can reduce the amount of liquid collected in the support part, and the wide lower setting increases the stability and firmness of the support part.

[0033] In some embodiments, the side of the support portion away from the groove wall is named the second side 22, and the side of the groove wall of the support portion located on the first guide groove 31 is the first side 21, that is, the first side 21 and the inclined groove wall of the first guide groove 31 are the same surface, and the second side 22 is also inclined. In the same support portion, the inclination direction of the second side 22 is opposite to that of the first side 21, so that the support portion becomes a structure similar to an isosceles trapezoid that is wide at the bottom and narrow at the top, further increasing the stability and firmness of the support portion.

[0034] See attached Figure 5 As shown, in some embodiments, during the connection of two adjacent conveying components 1, the two second side surfaces 22 of the supporting parts located on the two conveying components 1 form an approximately "V"-shaped structure, forming a second guide groove 32. The second guide groove 32 is arranged in parallel with the first guide groove 31 and can also be used to guide liquid.

[0035] See attached Figure 5-6As shown, in some embodiments, a limiting member 4 is provided above the support member 2, and the limiting member 4 is located on both sides of the transmission direction of the transmission chain. During the transportation of the flower basket 9, the end plate 91 of the flower basket 9 is placed on the transmission chain and is located between the limiting members 4 on both sides of the transmission direction of the transmission chain. The setting of the limiting member 4 can prevent the flower basket 9 from falling off the transmission chain during the transmission process.

[0036] In some embodiments, a plurality of limiting members 4 are provided, symmetrically arranged above the supporting portion, for limiting the position of the flower basket.

[0037] See attached Figure 4-5 As shown, in some embodiments, the conveying assembly 1 includes a first connecting member 5 and a second connecting member 6, which are arranged at both ends of the conveying direction of the conveying chain, and two adjacent conveying assemblies 1 are connected by the first connecting member 5 and the second connecting member 6. Specifically, the first connecting member 5 of one conveying assembly 1 is connected to the second connecting member 6 of another conveying assembly 1, the first connecting member 5 is provided with a first connecting hole 51, the second connecting member 6 is provided with a second connecting hole 61, and the shaft pin passes through the first connecting hole 51 and the second connecting hole 61 to connect the first connecting member 5 and the second connecting member 6, thereby making the two adjacent conveying assemblies 1 hinged.

[0038] In some embodiments, two second connecting members 6 are provided, located on both sides of the transmission direction of the transmission chain, and a gap 7 is left between the two oppositely arranged second connecting members 6, and the width of the gap 7 is not less than the width of the first connecting member 5. During the connection process, the first connecting members 5 of adjacent conveying components 1 are located in the gap 7, and the shaft pins pass through the second connecting members 6, the first connecting members 5, and the second connecting members 6 to connect the adjacent conveying components 1. By connecting the second connecting members 6 at both ends of the first connecting member 5, the connection between the first connecting member 5 and the second connecting member 6 is made more secure.

[0039] In some embodiments, the first connector 5, the second connector 6, and the support member 2 of the conveying assembly 1 are integrally connected by injection molding. By integrally connecting the first connector 5, the second connector 6, and the support member 2, the conveying assembly 1 is more solid as a whole, and the first connector 5, the second connector 6, and the support member 2 will not loosen or be damaged.
