Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a tray for conveying a line body. Background Art

[0002] In the field of battery manufacturing, high-speed and high-cleanliness conveyor lines are commonly used for conveyor lines, while pallets refer to conveyor systems specially designed to convey battery cells or battery components quickly, efficiently and in a high-cleanliness environment on battery production lines. Pallets used for conveyor lines are an indispensable part of the battery manufacturing process, and they ensure the efficiency, quality and safety of the battery production process.

[0003] At present, in the production process of battery cells, belt lines are mostly used to transport battery cells between equipment in the assembly process. However, in order to meet the equipment efficiency and dust control requirements, high-speed and high-cleanliness conveyor lines are gradually introduced between the coil cutting (stacking) and assembly processes. Due to the differences in the line structure, belt lines and high-speed and high-cleanliness conveyor lines have different structural requirements for battery cell pallets. Corresponding pallets need to be designed for different conveyor line bodies, and can only be used in the corresponding line bodies, resulting in a large amount of pallets required. The general pallets in the industry are developed and designed based on two separate line bodies and are not compatible with the two line bodies, resulting in many types of molds required, high material costs, and increased costs for developing battery cell pallets for the entire line. Utility Model Content

[0004] In order to solve the above technical problems, the utility model solves the problem that the pallets that are not applicable to the high-speed and high-cleanliness conveyor line and the belt line are not applicable to each other. The specific technical solution is as follows:

[0005] A tray for a conveyor line body comprises a bottom plate capable of fixing a battery cell, wherein mounting edges are arranged around the bearing surface of the bottom plate, and a contact piece is detachably connected to the mounting edge, wherein the contact piece comprises a guide plate mounted on the bottom plate; wherein the bottom plate is transported on a belt line or a high-speed and high-cleanliness conveyor line via the guide plate.

[0006] Among them, the contact parts are on the installation edge, and the guide plate is transmitted through the belt line, or contacts with the rollers of the high-speed and high-cleanliness conveyor line. The rollers drive the bottom plate to move through the guide plate, thereby driving the battery cells on the bottom plate to be transferred. The guide plate and the bottom plate are detachable and installed. By replacing different guide plates to adapt to the belt line or high-speed and high-cleanliness conveyor line, only the contact parts of the bottom plate need to be replaced to be compatible with the two line bodies. Different line bodies use a unified tray to reduce the number of bottom plates required. The tray molds of the two line bodies are unified and do not need to be redesigned and manufactured.

[0007] Preferably, the bottom plate includes a tray, the tray is provided with adjustment slots around the battery cells, the adjustment slots are provided with limit blocks that can slide and be locked, and a plurality of limit blocks are against the periphery of the battery cells. The limit blocks can be against the periphery of the battery cells through the adjustment slots to lock the battery cells, thereby meeting the placement requirements of battery cells of different sizes.

[0008] Preferably, the tray is provided with concave platforms at both ends of the battery cell, wherein the concave platforms are used to place metal parts connected to the ends of the battery cell, so as to avoid friction between the metal parts and the tray during the processing of the battery cell, thereby generating metal chips and affecting subsequent welding.

[0009] Preferably, the tray is provided with avoidance grooves on both sides of the battery cells, wherein the avoidance grooves facilitate the mechanical grippers to grasp the battery cells on the tray without air gaps.

[0010] Preferably, the top of the tray is provided with evenly arranged stacking platforms and stacking columns, the bottom of the tray is provided with positioning holes plugged into the stacking columns on the adjacent trays, and the stacking platforms are fitted with guide plates on the adjacent trays. The upper tray plugs the positioning holes into the stacking columns of the lower tray, the ends of the positioning holes lean against the steps of the stacking columns, and the guide plates lean against the stacking platforms, the guide plates lean against the stacking platforms and the positioning holes lean against the steps of the stacking columns to ensure the levelness of the trays and improve the stacking effect.

[0011] Preferably, the limit block includes a stopper against the side of the battery cell, a convex block extending to the adjustment slot, and a locking member penetrating the adjustment slot and locked. The locking member can be a bolt and a nut, a pin, a set screw, and multiple stoppers are used to close to the periphery of the battery cell to meet the placement requirements of battery cells of different sizes.

[0012] Preferably, the guide plate has a size that at least covers the mounting edge, wherein the guide plate effectively prevents dust from getting stuck in the mounting edge, thereby preventing dust from accumulating in the mounting edge and affecting the production of battery cells.

[0013] Preferably, an opening is provided at one end of two adjacent guide plates, and the guide plates are adapted to the blocker of the belt line through the opening. The hole is blocked by the blocker, so that the tray is blocked.

[0014] Preferably, the guide plate is provided with a notch corresponding to the adjustment slot, wherein a screwdriver can be inserted into the notch, and the stopper can be locked on the adjustment slot by adjusting the locking piece to keep the stopper in close contact with the side of the battery cell.

[0015] Preferably, a clamping protrusion and a clamping concave block are respectively provided at both ends of the guide plate, and two adjacent guide plates are clamped together by the clamping protrusion and the clamping concave block and installed on the mounting edge. Among them, the ends of the two adjacent guide plates close to each other are clamped together and pressed against each other by the clamping protrusion and the clamping concave block, and the clamping protrusion and the clamping concave block are locked by bolts, so that the bottom end of the entire guide plate is continuous and flush, ensuring smooth transmission of the line body.

[0016] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0017] The utility model changes the contact structure between the bottom of the tray and the conveyor line by replacing the type of contact piece, so as to meet the unique requirements of high-speed and high-cleanliness conveyor lines and belt lines for the tray structure. Compared with the prior art, the present application can achieve compatibility with multiple types of battery cells, and when it is applicable to high-speed and high-cleanliness conveyor lines, it also meets the requirements of belt lines. The molds of the two line trays are unified, and there is no need to redesign and manufacture them, which is low in cost.

[0018] The battery cells are placed on the tray, and the limit blocks form a placement surface on the tray to accommodate the battery cells. The limit blocks and the bottom plate are detachable from each other, and the size of the placement surface can be adjusted by adjusting the position of the limit blocks on the bottom plate, thereby meeting the placement requirements of battery cells of different sizes.

DETAILED DESCRIPTION

[0030] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0031] Belt conveyors and high-speed, high-cleanliness conveyor lines are both basic conveying equipment. During the production and manufacturing process, battery cells need to be transferred between different process stages. Choosing a suitable conveying system is crucial to ensuring production efficiency and battery cell quality.

[0032] like Figure 1-Figure 5 As shown, a tray for a conveyor line includes a base plate 10 capable of fixing a battery cell 20, and mounting edges 110 are provided on all four sides of the bearing surface of the base plate 10, and a contact member 30 is detachably connected to the mounting edge 110, and the contact member 30 includes a guide plate 301 installed on the base plate 10; wherein the base plate 10 is transported on a belt line or a high-speed and high-cleanliness conveyor line through the guide plate 301.

[0033] The battery cell 20 is placed on the bottom plate 10, and the contact piece 30 is on the installation edge 110. The guide plate 301 is transmitted through a belt line, or contacts with the rollers of a high-speed and high-cleanliness conveyor line. The rollers drive the bottom plate 10 to move through the guide plate 301, thereby driving the battery cell 20 on the bottom plate 10 to be transported. The guide plate 301 and the bottom plate 10 are detachable and installable. By replacing different guide plates 301 to adapt to the belt line or the high-speed and high-cleanliness conveyor line, only the contact piece 30 of the bottom plate 10 needs to be replaced to be compatible with the two lines, thereby reducing the number of bottom plates 10 required. The material of the bottom plate 10 adopts modified engineering plastics.

[0034] like Figure 1-Figure 5As shown, the bottom plate 10 includes a tray 101, and the tray 101 is provided with adjustment grooves 103 located around the battery cells 20. The adjustment grooves 103 are provided with limit blocks 109 that can slide and be fastened and locked. A plurality of limit blocks 109 are against the periphery of the battery cells 20, wherein the battery cells 20 are placed on the tray 101, and after the limit blocks 109 are adjusted, the limit blocks 109 are against the periphery of the battery cells 20, and the limit blocks 109 are locked. The limit blocks 109 can limit the battery cells 20 on the tray 101, so that the battery cells 20 are fixed on the tray 101. Preferably, the limit blocks 109 are against the membrane on the side of the battery cells 20, so that the limit blocks 109 are in soft contact with the battery cells 20.

[0035] like Figure 1-Figure 3 and Fig.10 As shown, the limit block 109 includes a stopper 1091 leaning against the side of the battery cell 20, a protrusion 1092 extending to the adjustment groove 103, and a locking member 1093 penetrating the adjustment groove 103 and locked, wherein the stopper 1091 leans against the side of the battery cell 20, and the protrusion 1092 extends into the adjustment groove 103, so that the stopper 1091 moves along the adjustment groove 103 until the stopper 1091 leans against the battery cell 20, and the stopper 1091 can be locked on the tray 101 by the locking member 1093, wherein the locking member 1093 can be bolts and nuts, pins, and set screws, and multiple stoppers 1091 are used to lean against the periphery of the battery cell 20 to meet the placement requirements of battery cells 20 of different sizes, and the stopper 1091 is preferably made of modified engineering plastics.

[0036] like Figure 3 As shown, the tray 101 is provided with recesses 106 at both ends of the battery cell 20, wherein the recesses 106 are used to place metal parts connected to the ends of the battery cell 20 to prevent the metal parts from rubbing against the tray 101 during the processing of the battery cell 20 to generate metal chips, thereby preventing subsequent welding from being affected. The bottom of the tray 101 is hollowed out and is designed with a number of reinforcing ribs to improve the structural strength of the tray 101.

[0037] The tray 101 is provided with avoidance grooves 104 on both sides of the battery cells 20 , wherein the avoidance grooves 104 facilitate the mechanical grippers to grab the battery cells 20 on the tray 101 without air gaps, and the placement surface of the battery cells 20 and the edges of the avoidance grooves 104 are designed with rounded corners.

[0038] like Figure 3 and Figure 6-Figure 9As shown, the top of the tray 101 is provided with a uniformly arranged stacking platform 105 and a stacking column 107, and the bottom of the tray 101 is provided with a positioning hole 102 for plugging with the stacking column 107 on the adjacent tray 101, and the stacking platform 105 is fitted with the guide plate 301 on the adjacent tray 101, wherein the stacking platform 105 and the stacking column 107 can be uniformly arranged around the tray 101, and at least one stacking column 107 is provided, preferably two, to ensure that the stacking between the upper and lower adjacent trays 101 is more stable, and one of them is selected, that is, The stacking columns 107 are arranged at the four corners of the pallet 101, and two stacking columns 107 are arranged on both sides of the middle part of the pallet 101. When the pallets 101 need to be stacked, the upper pallet 101 inserts the positioning hole 102 into the stacking column 107 of the lower pallet 101, and the end of the positioning hole 102 rests on the step of the stacking column 107. At the same time, the guide plate 301 rests on the stacking table 105, and the guide plate 301 rests on the stacking table 105 and the positioning hole 102 rests on the step of the stacking column 107 to ensure the horizontality of the pallet 101.

[0039] like Figure 4 and Figure 5 As shown, the size of the guide plate 301 at least covers the mounting edge 110, and the mounting edge 110 is used to install the guide plate 301. Since there is a groove body on the mounting edge 110, the guide plate 301 blocks the mounting edge 110. During the transportation of the tray 101, dust can be effectively prevented from being stuck in the mounting edge 110, so as to avoid the subsequent accumulation of dust in the mounting edge 110 and affect the production of the battery cell 20.

[0042] A notch 304 corresponding to the adjustment slot 103 is provided on the guide plate 301, and the notch 304 can effectively reserve space with the adjustment slot 103. When the position of the stopper 1091 needs to be adjusted, a screwdriver can be inserted into the notch 304, and the stopper 1091 can be locked on the adjustment slot 103 by adjusting the locking piece 1093, so as to keep the stopper 1091 fit and fixed to the side of the battery cell 20.

[0043] As the second embodiment of this application:

[0044] like Figure 5 , Figure 8 and Fig. 9 As shown, in order to use a high-speed and high-cleanliness conveyor line, a card protrusion 306 and a card recess 307 are respectively provided at both ends of the guide plate 301, and two adjacent guide plates 301 are engaged through the card protrusion 306 and the card recess 307 and installed on the installation edge 110, wherein the tray 101 is provided with a plurality of card slots 108 at the guide plate 301, and a plurality of card ports 305 corresponding to the card slots 108 are provided on the guide plate 301, and the guide plate 301 is connected to the card slot 108 through the card ports 305. 8 is connected with the tray 101, the guide plate 301 is L-shaped, and the ends of two adjacent guide plates 301 that are close to each other are engaged and pressed against each other through the card protrusion 306 and the card recess block 307, and the card protrusion 306 and the card recess block 307 are locked by bolts at the same time, so that the bottom end of the entire guide plate 301 is continuous and flush. When the guide plate 301 is transmitted by rollers, the guide plate 301 is in contact with at least three rollers, and the continuous guide plates 301 are transported by the rollers.

[0045] In order to improve the structural strength of the guide plate 301 of the present application, the guide plate 301 is provided with reinforcing ribs, and the material is polymer PE.

[0046] In the actual application of the utility model, the battery cell 20 is placed on the bottom plate 10, and in the placement surface formed after being fixed by the limit block 109, since the limit block 109 and the bottom plate 10 can be disassembled from each other, the size of the placement surface can be adjusted by adjusting the position of the limit block 109 on the bottom plate, thereby meeting the placement requirements of battery cells 20 of different sizes; at the same time, the contact structure between the bottom of the tray 101 and the conveyor line can be changed by changing the type of the contact member 30, so as to meet the unique requirements of the high-speed and high-cleanliness conveyor line and the belt line. Compared with the prior art, the utility model can achieve compatibility with multiple types of battery cells 20, and when it is applicable to the high-speed and high-cleanliness conveyor line, it also meets the requirements of the belt line.
