Description

Technical Field

[0001] This utility model relates to a positioning fixture for a non-adhesive stacking module of battery cells with output cells on the pole side, belonging to the field of power battery manufacturing technology. Background Technology

[0002] In existing battery manufacturing processes, cell stacking is typically accomplished by automated equipment. The core process relies on the coordinated work of robots, stepper motors, and related components to ensure precise stacking positioning. However, in actual debugging, significant time is often spent adjusting the robot's trajectory, the stepper motor's motion parameters, and the positional accuracy of related components. While this traditional method, heavily reliant on equipment debugging, is suitable for large-scale, long-cycle production, it lacks flexibility for small-batch, short-cycle production needs and struggles to quickly respond to prototype manufacturing requirements. Therefore, a more convenient and flexible method is urgently needed to address the frequent adjustments and rapid switching required during prototype manufacturing, thereby improving production efficiency and reducing debugging costs. Utility Model Content

[0003] To address the shortcomings of existing production methods, this utility model provides a positioning fixture suitable for non-adhesive stacking modules of battery cells with output cells from the electrode side, thus solving the problems mentioned in the background art.

[0004] This utility model provides a positioning fixture for a non-adhesive stacked module of battery cells with terminals on the side of the electrode, characterized in that the fixture includes: The carrier 1 has two long reference blocks 2 fixedly installed on each side. Two short reference blocks 3 are evenly distributed and fixedly installed between the two long reference blocks 2 on the same side. Short connecting blocks 4 are fixedly installed above the middle of the long reference blocks 2 and the short reference blocks 3 to connect them into one unit. Long connecting blocks 5 are fixedly installed above the middle of the two short reference blocks 3 to connect them into one unit. Two support seats 6 are fixedly installed on each short reference block 3. The card plate mounting plate 7 is provided in four parts. Each card plate mounting plate 7 is fixedly mounted on the support base 6 and symmetrically distributed on both sides of the carrier 1. Each card plate mounting plate 7 has a card plate 8 fixedly mounted on its inner side. A card plate positioning fixture 9 is inserted between two card plates 8 on the same side.

[0005] Furthermore, the card plate 8 has a comb-like structure with several slender spindle-shaped protrusions 801 evenly distributed on it.

[0006] Furthermore, a keyway 10 is provided on one side of each long reference block 2 on the carrier 1, and a flat key 11 is provided in each keyway 10.

[0007] Furthermore, the card plate 8 is made of POM or PP material.

[0008] The beneficial effects of this utility model are as follows: This utility model tooling uses the feature points of the carrier itself for overall positioning, and can be quickly installed and disassembled on different carriers. Through the protruding structure of the clamping plate, the position of the battery cell stacking is accurately limited, ensuring that the manually stacked modules have high consistency, high ease of operation and cost advantage, and at the same time, it can provide good quality assurance for sample production.

[0018] The following is a specific embodiment of this utility model with reference to the accompanying drawings, and the structure of this utility model is described in detail. It should be noted that the scope of application of this utility model is not limited to the following embodiment; all similar structures based on this utility model are within the scope of application of this utility model.

[0019] One type of positioning fixture of this utility model is applicable to the non-adhesive stacking module of battery cells with output from the terminal post side, such as Figures 1-4 As shown, the tooling includes: The carrier 1 has two long reference blocks 2 fixedly installed on each side. Two short reference blocks 3 are evenly distributed and fixedly installed between the two long reference blocks 2 on the same side. Short connecting blocks 4 are fixedly installed above the middle of the long reference blocks 2 and the short reference blocks 3 to connect them into one unit. Long connecting blocks 5 are fixedly installed above the middle of the two short reference blocks 3 to connect them into one unit. Two support seats 6 are fixedly installed on each short reference block 3. Four mounting plates 7 are provided, each of which is fixedly installed on the support base 6 and symmetrically distributed on both sides of the carrier 1. Each mounting plate 7 has a mounting plate 8 fixedly installed on its inner side. After tightening, the two plates fit together completely to ensure no warping. The mounting plates 8 are divided into four sections, with two pairs on the same side and two pairs opposite each other. A mounting plate positioning fixture 9 is inserted between two mounting plates 8 on the same side. If the stacking accuracy requirement is high, after the tooling is assembled, tools such as a level and a coordinate measuring machine are needed to check the levelness and straightness of the support base 6, mounting plates 8, etc.

[0020] As a further description of this embodiment, such as Figure 2 As shown, the card plate 8 has a comb-like structure with several slender spindle-shaped protrusions 801 evenly distributed on it. The distance between the center points of two protrusions is the standard value of the width of the electrode post of the battery cell 12 plus the stacking gap.

[0021] As a further description of this embodiment, such as Figure 4 As shown, a keyway 10 is provided on one side of each long reference block 2 on the carrier 1, and a flat key 11 is provided in each keyway 10 to achieve fixation in the X direction on the carrier 1.

[0022] As a further description of this embodiment, the card plate 8 is made of POM or PP material and needs to be specially made according to the pole shape and stacking gap of each project in order to position the poles of the battery cell 12.

[0023] The working process of this utility model is as follows: First, assemble the stacking and positioning fixture. After using the clamping positioning jig 9 to determine the flatness of the clamping plate 8, the operator holds the battery cell 12 vertically along the direction of the clamping plate 8 and smoothly inserts the battery cell 12 one by one along the slender spindle-shaped protrusions 801 until the required number of battery cells 12 are met. The slender spindle-shaped protrusions 801 on the clamping plate 8 structure restrict the position of the battery cell 12 in the X and Y directions, and the plane of the carrier 1 below restricts the position of the battery cell 12 in the Z direction. The regularly arranged slender spindle-shaped protrusions 801 ensure the consistency of the X, Y, and Z directions of adjacent battery cells 12, ensuring good dimensional and positional characteristics of the stacked module in subsequent processing.

[0024] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this invention.
