Abstract
Description
Technical Field
[0001] This invention relates to the field of aluminum-cased battery assembly technology, and in particular to a manual wire cell adhesive application device and its operation method. Background Technology
[0002] The manufacturing process of rectangular batteries such as lithium batteries, nickel-metal hydride batteries, and nickel-cadmium batteries is roughly as follows: stacking → winding → adhesive application. In the winding step, a certain length of separator is wound on the battery cell, while the adhesive application step is to attach the end of the separator to prevent it from loosening.
[0003] Currently, battery cell adhesive application devices are generally large in size, consume a lot of energy, and are expensive. Manual lines are generally too small to be suitable for using large adhesive application equipment. Some battery cell adhesive application devices do not have battery cell positioning functions, and the adhesive application quality of butterfly-welded battery cells is easily affected by angle and other issues during the adhesive application process.
[0004] For example, a semi-automatic battery cell adhesive applicator disclosed in Chinese patent literature, publication number CN203760573U, is used in the battery cell manufacturing industry. It includes a base and a green adhesive cutter for cutting the adhesive. The base has a drive device and a battery cell placement surface. The drive device is connected to a green adhesive suction cup, which moves the suction cup toward and away from the placement surface. One side of the suction cup has a green adhesive placement rod and a movable block that moves toward and away from the suction cup; the other side has a pressing block that moves toward and away from the suction cup. The movable block has a green adhesive tensioning cylinder; the pressing block has a pressing cylinder connected to a pressure plate, which pushes the pressure plate toward the suction cup. The disadvantages are that the equipment occupies a large space, cannot be used on manual lines, and lacks a hinge mechanism, making it prone to issues like angle affecting the adhesive application quality when applying adhesive to butterfly-welded battery cells. Summary of the Invention
[0005] The purpose of this invention is to overcome the problem in the prior art where the angle affects the adhesive application quality of the battery cell during the adhesive application process. This invention provides a manual battery cell adhesive application device and its operation method, which effectively protects the battery cell tabs from being torn by the hinge mechanism, protects the welding strength of the connecting pieces, and improves the adhesive application quality.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A manual wire core adhesive applicator includes:
[0008] A base plate for mounting battery cells, wherein the base plate has a hollow structure in the middle and the battery cells are arranged on one side of the base plate;
[0009] A bayonet, used to fix the battery cell, is provided on both sides of the battery cell, and the length direction of the bayonet is parallel to the length direction of the battery cell;
[0010] A hinge mechanism for bending the base plate, the hinge mechanism being disposed in the middle of the base plate;
[0011] A limiting block is used to limit the position of the battery cell, and the length direction of the limiting block is parallel to the width direction of the battery cell.
[0012] In this invention, the base plate is used to house the battery cells. The adhesive application area features a hollow design for easy manual application. During application, the adhesive tape and the application device do not interfere with each other. There is a certain height difference between the adhesive application area and the surface of the battery cell. When the application device is closed, the hollowed-out area exposes the adhesive application area at a 90° outward angle. This makes manual application more convenient and less prone to errors, misalignment, or damage to the battery cell. A hinge mechanism is used to bend the base plate. This hinge mechanism solves the problem of the angle affecting the adhesive application quality during the application of adhesive to butterfly-welded battery cells. This hinge mechanism allows for both positive and negative hinge application to the front and back of the butterfly-welded battery cell, providing excellent performance. The adhesive application effect is excellent. The hinge mechanism aligns the axis connecting the battery cell with the bending position of the battery cell, effectively protecting the battery cell tabs from tearing and maintaining the welding strength of the connecting pieces. The bayonet is used to fix the battery cell, preventing vertical displacement. The limiting block is used to limit the position of the battery cell, preventing horizontal displacement. The adhesive application device has a battery cell positioning function; placing the battery cell in the bayonet allows for positioning and locking. It can accommodate and apply adhesive to battery cells of different sizes. This invention has a wide range of applications and is suitable for applying adhesive to all manually welded butterfly-type battery cells. The adhesive application qualification rate using this device is 99.9%. This device improves adhesive application efficiency and offers high ease of operation.
[0013] Preferably, the base plate includes a first base plate, a second base plate, and a connecting plate for connecting the first base plate and the second base plate. The connecting plate is disposed between the first base plate and the second base plate and is connected to the first base plate and the second base plate via a hinge mechanism. The connecting plate is disposed between the first base plate and the second base plate, located at the edge, with a gap in the middle, forming a hollow design.
[0014] Preferably, the bayonet includes a first bayonet and a second bayonet, which are respectively disposed on both sides of the battery cell. The first bayonet is rotatably connected to the base plate, and the second bayonet is fixedly connected to the base plate. The first bayonet is a rotary bayonet, and the second bayonet is a fixed bayonet. Opening the rotary bayonet allows the battery cell to be inserted and fixed or removed.
[0015] Preferably, the battery cell includes a first battery cell and a second battery cell. The first battery cell contacts a first base plate, and the second battery cell contacts a second base plate. The first and second battery cells are connected by a connecting piece. The first and second battery cells respectively abut against the surfaces of one side of the first and second base plates. The first and second battery cells are connected by a connecting piece, and the bend of the connecting piece is aligned with the bend of the hinge mechanism, which effectively protects the battery cell tabs from being torn and protects the welding strength of the connecting piece.
[0016] Preferably, the hinge mechanism includes a first hinge, a second hinge, a third hinge, and a fourth hinge, wherein the first and second hinges are disposed on the side of the first base plate near the second base plate, and the third and fourth hinges are disposed on the side of the second base plate near the first base plate.
[0017] Preferably, the openings of the first and second bayonets are slightly larger than the thickness of the battery cell. This larger opening facilitates the insertion of the battery cell into the first and second bayonets.
[0018] A method for operating a manual wire core adhesive applicator includes the following steps:
[0019] S1. Prepare the adhesive applicator and the battery cell. Adjust the position of the limit block of the adhesive applicator to make the size of the battery cell to be adhesiveped suitable.
[0020] S2, the battery cell is placed into the adhesive applicator;
[0021] S3, Apply adhesive to the battery cell;
[0022] S4, remove the battery cell;
[0023] S5, after applying the adhesive, lay the adhesive applicator flat, open the first latch, and remove the battery with the tape applied horizontally.
[0024] By implementing the above technical solution, the adhesive applicator adjusts the position of the limiting block to ensure that the size of the battery cell to be taped is suitable. The device is placed horizontally and the first latch is opened. The battery cell is inserted into the second latch, and then the first latch is manually rotated to close the battery cell and fix it in place. The adhesive applicator is then manually placed upright and the first, second, third, and fourth hinges are rotated to a certain angle. During rotation, the connecting piece is manually bent at the connection position between the connecting piece and the first and second battery cells to avoid damaging the battery cell tabs. The front and back adhesive application are connected by rotating and bending the hinge mechanism on both sides to make the angle between the battery cell and the connecting piece 90°, so as to facilitate manual application of adhesive to the battery cell. After the adhesive is applied, the adhesive applicator is laid flat, the first latch is opened, and the battery with the tape applied is removed horizontally.
[0025] Preferably, the process described in step S2 involves placing the battery cell into the adhesive applicator, then horizontally placing the adhesive applicator and rotating it to open the first slot, inserting the battery cell into the second slot, and then rotating it to close the first slot.
[0026] Preferably, the adhesive application to the battery cells described in step S3 includes manually standing the adhesive application device upright and rotating the first, second, third, and fourth hinges to a certain angle. During rotation, the connecting piece is manually bent at the connection point between the first and second battery cells. The adhesive application on the front and back sides is achieved by rotating and bending the hinge mechanism on both sides to make the adhesive angle between the battery cell and the connecting piece 90°. Four strips of adhesive tape are applied to each of the front and back sides of the connection point between the two battery cells. The adhesive application device is positioned in the front and back directions corresponding to the folded state of the battery cells.

Detailed Implementation
[0033] The present invention will be further described below with reference to the accompanying drawings and examples. Specific Implementation Example 1:
[0035] like Figure 1 or Figure 2 or Figure 3 or Figure 4 As shown, a manual wire core adhesive applicator includes a base plate 1, a latch 3, a hinge mechanism 4, and a limiting block 5. The base plate 1 has a hollow structure in the middle, and the wire core 2 is disposed on one side of the base plate 1. The latch 3 is disposed on both sides of the wire core 2, and the length direction of the latch 3 is parallel to the length direction of the wire core 2. The hinge mechanism 4 is disposed in the middle of the base plate 1, and the length direction of the limiting block 5 is parallel to the width direction of the wire core 2. The base plate 1 includes a first base plate 1.1, a second base plate 1.2, and a connecting plate 1.3 for connecting the first base plate 1.1 and the second base plate 1.2.

The latch 3 includes a first latch 3.1 and a second latch 3.2, which are respectively located on both sides of the battery cell 2. The first latch 3.1 is rotatably connected to the base plate 1, and the second latch 3.2 is fixedly connected to the base plate 1. The battery cell 2 includes a first battery cell 2.1 and a second battery cell 2.2. The first battery cell 2.1 is in contact with the first base plate 1.1, and the second battery cell 2.2 is in contact with the second base plate 1.2. The first battery cell 2.1 and the second battery cell 2.2 are connected by a connecting piece 6. The hinge mechanism 4 includes a first hinge 4.1, a second hinge 4.2, a third hinge 4.3, and a fourth hinge 4.4. The first hinge 4.1 and the second hinge 4.2 are located on the first base plate 1.1 near the second base plate 1.2, and the third hinge 4.3 and the fourth hinge 4.4 are located on the second base plate 1.2 near the first base plate 1.1. The openings of the first bayonet 3.1 and the second bayonet 3.2 are slightly larger than the thickness of the battery cell 2.
[0036] In the above technical solution, the base plate 1 is used to house the battery cell 2. The adhesive application position adopts a hollow design to facilitate manual adhesive application. During adhesive application, the tape and the adhesive application device will not interfere with each other. There is a certain height difference between the adhesive application position of the battery cell welding and the surface of the battery cell 2. When the adhesive application device is closed, the hollow position is exposed at an outward 90° angle, making manual adhesive application more convenient and less likely to be misplaced, crooked, or damaged. The hinge mechanism 4 is used to bend the base plate. The configuration of the hinge mechanism 4 solves the problem that the angle affects the adhesive application quality during the adhesive application process of the butterfly welded battery cell. This hinge mechanism 4 can realize the application of adhesive to the front and back of the butterfly welded battery cell, and has a good adhesive application effect. This hinge mechanism 4 connects the axis of the battery cell 2 and the bending of the battery cell 2. Maintaining consistent positioning effectively protects the battery cell 2's tabs from tearing and strengthens the welding of the connecting pieces. The bayonet 3 secures the battery cell, preventing vertical displacement. The limiting block 5 limits the battery cell's position, preventing horizontal displacement. The adhesive applicator has a battery cell 2 positioning function; placing the battery cell 2 in the bayonet 3 allows for positioning and locking. It can accommodate and applicate battery cells 2 of different sizes. This invention has a wide range of applications, suitable for adhesive applicating all manually welded butterfly-type battery cells. Using this device, the adhesive applicability rate is 99.9%. This device improves adhesive applicability and offers high operational convenience. The connecting plate 1.3 is positioned between the first base plate 1.1 and the second base plate 1.2, located at the edge with a gap in the middle, forming a hollow design. The first bayonet 3.1 is a rotary bayonet, and the second bayonet 3.2 is a fixed bayonet. Opening the rotary bayonet allows the battery cell 2 to be inserted, fixed, or removed. The first battery cell 2.1 and the second battery cell 2.2 respectively abut against the surfaces of the first base plate 1.1 and the second base plate 1.2. The first battery cell 2.1 and the second battery cell 2.2 are connected by a connecting piece 6. The bent part of the connecting piece 6 is aligned with the bent part of the hinge mechanism 4, which effectively protects the battery cell 2's tabs from being torn and protects the welding strength of the connecting piece 6. The openings of the first latch 3.1 and the second latch 3.2 are larger than the thickness of the battery cell 2, making it easier for the battery cell 2 to be inserted into the first latch 3.1 and the second latch 3.2. Specific Implementation Example 2:

Apply adhesive to the front and back sides and rotate and bend the connection through the hinge mechanism 4 on both sides so that the adhesive angle between the battery cell 2 and the connecting piece 6 is 90°.
[0042] S4, remove battery cell 2;
[0043] S5, after applying the adhesive, lay the adhesive applicator flat, open the first latch 3.1, and horizontally remove the battery with the adhesive tape applied.

The device is then placed horizontally and the first latch 3.1 is opened. The battery cell 2 is inserted into the second latch 3.1, and then the first latch 3.1 is manually rotated to close it and fix the battery cell 2. The adhesive applicator is then manually erected and the first hinge 4.1, second hinge 4.2, third hinge 4.3, and fourth hinge 4.4 are rotated to a certain angle. During rotation, the auxiliary connecting piece 6 is manually engaged with the first battery cell 2.1 and the second hinge 4.4.
