[0001] The present application relates to the technical field of energy storage battery electrode grid processing, in particular to a tension type carrier for an electrode grid production line. BACKGROUND

[0002] In the composition of energy storage batteries, the electrode grid of the battery is one of the most important components, and the quality of the electrode grid shape greatly affects the performance of the battery, directly determining the contact area with the active material, and thus affecting the energy storage efficiency and energy storage size.

[0003] As shown in Figure 1 The grid is composed of a U-shaped outer frame 41 at the top, a lead beam 43 at the bottom, and a plurality of arc single wires 42. The arc single wire 43 and the U-shaped outer frame 41 are made of lead-clad aluminum wire material. In the electrode grid production line, a corresponding carrier is needed to complete the electrode grid assembly and welding work.

[0004] A battery grid automatic clamping device is disclosed in CN117564964A, which controls the opening and retraction of the upper and lower two floating pin shafts through a diameter-gradually-changing movable push rod, thereby achieving clamping of the battery grid. However, this battery grid automatic clamping device is mainly used for assembly. However, when producing the electrode grid, after the arc single wire and the U-shaped outer frame are produced, they need to be transferred from the corresponding production equipment to the carrier. During the transfer process, the lead layer on the outside of the lead-clad aluminum wire material is easily damaged.

[0005] Therefore, there is a need for an electrode grid carrier that reduces damage to the wire material during the transfer process. SUMMARY

[0006] To solve the above problems, the present application provides a tension type carrier for an electrode grid production line, which adopts a double-layer plate structure to uniformly adjust the slot spacing, thereby ensuring the quality of the grid while improving the adjustment efficiency.

[0007] Specifically, the present application is implemented as follows:

[0009] A fixed component having a limiting assembly and a plurality of protrusions thereon, the limiting assembly being used to limit the periphery of the grid;

[0010] A movable component arranged in layers with the fixed component, having a plurality of columns thereon, the columns and the corresponding protrusions forming a slot for placing the arc single wire of the grid; the movable component is slidably connected with the fixed component;

[0011] A resilient member connected at both ends to the fixed component and the movable component;

[0012] An adjustment assembly is located at the end of the movable part away from the elastic member, and includes:

[0013] moving parts;

[0014] A moving member slot is provided at one end of the movable member away from the elastic member, the moving member slot is divided into a narrow portion and a wide portion, the movable member is assembled in the moving member slot, and the diameter of the movable member is adapted to the narrow portion;

[0015] The moving member sliding pair is connected to the fixed member, and its side close to the moving member slot is connected to the moving member, and is used to drive the moving member to move along the moving member slot so that the moving member switches between the narrow part and the wide part of the moving member slot.

[0016] Furthermore, when the movable member is located in the narrow portion, the elastic member is in an extended state, and the slot gap is larger than the size of the two arc-shaped single wires when they are put together;

[0017] When the moving part moves into the wide portion, the elastic part drives the movable part to move, the gap in the slot is reduced, and the arc-shaped single wire is compressed.

[0018] Furthermore, when the moving part is located in the narrow portion, the slot gap is m larger than the size of the two arc-shaped single wires when they are put together, and the width difference between the narrow portion and the wide portion is n, where n>m.

[0019] Furthermore, the movable component is provided with a spring groove, a movable spring hanging plate is fixedly arranged in the spring groove, a fixed spring hanging plate is provided on the fixed component, the movable spring hanging plate is coaxially installed with the fixed spring hanging plate, and the movable spring hanging plate and the fixed spring hanging plate are connected by an elastic member.

[0020] Furthermore, the elastic member is a spring.

[0021] Furthermore, the limiting component includes:

[0022] A plurality of stoppers are provided on either side of the fixed component, and form a slot between the stoppers and the uprights to compress the U-shaped outer frame of the grid and the arc-shaped single wires of the grid;

[0023] The long boss is used to limit the top of the U-shaped outer frame of the grid;

[0024] Multiple lead beam limiting bosses for limiting the lead beams of the grid;

[0025] The movable component is provided with a plurality of pressing blocks, which are arranged opposite to the stop blocks. The pressing blocks, the stop blocks, the long bosses and the plurality of lead beam limiting bosses together form a tensioning area of ​​the grid.

[0026] Furthermore, positioning sleeves for positioning are provided on both sides of the fixing component.

[0027] Furthermore, the movable component is connected to the fixed component through a panel sliding pair.

[0028] Furthermore, the movable component is arranged under the fixed component, and the fixed component is provided with a plurality of through holes for the movement of the columns. After the columns pass through the through holes, slots for placing the arc-shaped single wires of the grid are formed between the columns and the corresponding protrusions.

[0029] Furthermore, a pulling plate for driving the moving member to move is provided on the sliding pair of the moving member.

[0030] Working principle of the present invention:

[0031] In the initial state, the moving part is located in the narrow part of the moving part slot. At this time, the spring on the other side is in a stretched state, and the slot gap is large, which makes it easy for the arc-shaped single wire and the U-shaped outer frame to be placed in the carrier. After the arc-shaped single wire and the U-shaped outer frame are placed in the carrier, a drive is applied on the pull plate in the direction of the sliding pair of the moving part. When the moving part moves into the wide part of the moving part slot, the outer inner wall of the wide part of the moving part slot is separated from the moving part (the side of the moving part slot close to the spring is the inner side, and the side away from the spring is the outer side). At this time, the spring contracts. While the spring contracts and pulls, it drives the moving part to move, that is, drives the column to move toward the protrusion, reduces the slot gap, and compresses the grid. After moving into place, the moving part contacts the outer inner wall of the wide part of the moving part slot and detaches from the inner inner wall of the wide part of the moving part slot, limiting the further contraction of the spring, ensuring the pressing force, and avoiding excessive compression, which causes the grid to deform or damage it.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] (1) The present invention adopts a double-layer panel structure. By switching the moving part from the narrow part to the wide part, the tension of the elastic part during recovery is utilized to reduce the slot gap, thereby achieving the effect of tightening the grid and making adjustment convenient.

[0034] (2) When tightening, the moving part contacts the inner wall of the outer side of the wide part of the moving part groove, limiting the movement of the moving part, ensuring the tightening force while avoiding excessive elastic force of the elastic part, excessive tightening, causing deformation of the grid or damage to it.

[0046] Example 1

[0047] like Figure 2-5As shown, this embodiment provides a tensioning carrier for an electrode grid production line, comprising: a plate-like fixed component 1, a movable component 2, an elastic member, and an adjustment assembly. The fixed component 1 is positioned above the movable component 2. The upper fixed component 1 is provided with a limit assembly and several protrusions. The limit assembly comprises an upper long boss 18a, three lower lead beam limit bosses 18b, and multiple side blocks 19. The long boss 18a limits the top of the motor grid U-shaped outer frame 41, while the three lower lead beam limit bosses 18b limit the lead beams 43 of the electrode grid. These two limits help maintain the shape and size of the electrode grid 4. The fixed component 1 is provided with eight strip holes 11a and through holes 11b. The eight strip holes 11a are process holes for individual equipment on the production line, facilitating the placement of curved single wires into the carrier. Part of the through-hole 11b is used to pass through the pillars and compression blocks 23 on the movable component 2, and together with the protrusion 18c, forms a groove for the compression grid 4. The remaining portion facilitates the drop of excess solder. Eight positioning sleeves 12 are installed around the fixed component 1 to locate the position of the carrier.

[0048] like Figure 6 As shown, the movable component 2 has ears 21 at its upper and lower portions, which are slidably connected to the fixed component 1 via a panel sliding pair 13. The movable component 2 is provided with a moving component slot 22, a clamping block 23, a large column 24, a small column 25, and a spring slot 27. The clamping block 23, the long boss 18a, the lead beam limiting boss 18b, and the stopper 19 together form a tensioning area for the grid 4.

The spring slot 27 is located on the opposite side of the movable component 2's moving component slot 22. A movable spring hanging plate 26 is disposed within the spring slot 27. The movable spring hanging plate 26 is connected to the fixed spring hanging plate 17 on the fixed component 1 via an elastic member (spring 3).

The moving piece slot 22 is divided into a narrow part 22a and a wide part 22b, and the diameter of the moving piece 16 is matched with the narrow part 22a. The width difference between the narrow part 22a and the wide part 22b is n, when the moving piece 16 is located in the narrow part 22a, the gap of the clamping groove between the column and the protrusion 18c is larger than the size of the two wires of the arc single wire 42 after being brought together by m, at this time, the size of the clamping groove is larger, and the arc single wire 42 and the U-shaped outer frame 41 are facilitated to be put into the carrier. The design size n > m, when the moving piece 16 is located in the wide part 22b of the moving piece slot 22, the lower movable assembly 2 moves along the direction of the panel sliding pair 13 under the action of the pulling force of the spring 3, and the arc single wire 42 and the U-shaped outer frame 41 that have been put into the carrier are pressed tightly. Specifically, as shown in Figure 7-8 when the driving is applied on the pull plate 15 in the direction of the moving piece sliding pair 14 and the moving piece 16 is moved from the narrow part 22a to the wide part 22b, the outer side inner wall of the wide part 22b is separated from the moving piece 16, at this time, the spring 3 is contracted, and the movable part 2 is moved under the action of the contraction pulling force of the spring 3, that is, the column is moved to the protrusion 18c, the gap of the clamping groove is reduced, and the plate grid 4 is pressed tightly.
