It includes a base, a rotation drive, a first fixing member, a guide rod, a second fixing member, and an elastic member. When dispensing adhesive onto the cylindrical shell and cap, the shell and cap are first pre-assembled to form a semi-finished product. Then, the second fixing member is pushed away from the first fixing member. Next, the semi-finished product is moved between the first and second fixing members, and the cap is installed on the first fixing member. The second fixing member is then released, and under the action of the elastic member, it connects to the cylindrical shell of the semi-finished product and continuously presses against it. Finally, the rotation drive is controlled to drive the first fixing member to rotate the semi-finished product one revolution. During this process, the glue gun is aimed at the connection point between the cylindrical shell and the cap, achieving circular dispensing. Compared with manually rotating the cylindrical shell and dispensing adhesive, this reduces the operational difficulty, improves dispensing efficiency and uniformity, and thus improves product quality.

[0026] The combination of the guide rod and the elastic element ensures that the second fixing member consistently provides thrust to the cylindrical outer shell, improving the clamping and securing effect of the second and first fixing members on the semi-finished product.

[0027] The first fixing component of the cylindrical battery dispensing fixture forms an "active wheel structure," and the second fixing component forms a "driven wheel structure." Driven by the rotational drive component, it can reliably rotate the semi-finished product, improving the continuity and stability of dispensing. Furthermore, circular dispensing can be achieved by controlling the rotational drive component, making operation convenient.

This dispensing device for cylindrical batteries enables automatic dispensing between the cylindrical outer shell and the cap, further improving dispensing efficiency and uniformity, and reducing the labor intensity of workers.

[0043] Example 1

[0044] This embodiment provides a dispensing fixture for cylindrical batteries, which can clamp and fix pre-assembled cylindrical shell and cap and drive the cylindrical shell and cap to rotate synchronously to achieve dispensing at the connection between the cylindrical shell and cap, thereby improving dispensing efficiency and uniformity. It also has a simple structure, low cost, and can be applied to batteries of different sizes, making it highly versatile.

[0045] Specifically, such as Figure 1 and Figure 2 As shown, the cylindrical battery dispensing fixture 100 includes a base 110, a rotation drive 120, a first fixing member 130, a guide rod 140, a second fixing member 150, and an elastic member 160.

[0046] The rotating drive 120 is mounted on the base 110. The output end of the rotating drive 120 is connected to the first fixing member 130, which drives the first fixing member 130 to rotate. The first fixing member 130 is used to fix the cap. One end of the guide rod 140 is slidably connected to the base 110, and the other end is rotatably connected to the second fixing member 150. The guide rod 140 can slide to move the second fixing member 150 closer to or away from the first fixing member 130. The second fixing member 150 is used to fix the cylindrical shell. The elastic member 160 is configured to have a tendency to drive the guide rod 140 to move the second fixing member 150 closer to the first fixing member 130, so that the second fixing member 150 and the first fixing member 130 clamp and fix the pre-assembled cylindrical shell and cap.

[0047] The method for securing the cylindrical battery casing and cap using the dispensing clamp 100 is as follows:

[0048] First, the cylindrical outer shell and the cap are pre-assembled to form a semi-finished product;

[0049] Then, the second fixing member 150 is pushed away from the first fixing member 130, during which the elastic member 160 is compressed and stores elastic potential energy;

[0050] Then, while maintaining the position of the second fastener 150, move the semi-finished product between the first fastener 130 and the second fastener 150 and install the cap of the semi-finished product on the first fastener 130;

[0051] Finally, the second fastener 150 is released. Under the elastic force of the elastic member 160, the second fastener 150 is connected to the cylindrical shell of the semi-finished product and continuously presses against the cylindrical shell, so that the second fastener 150 and the first fastener 130 can always maintain the clamping and fixing of the semi-finished product.

[0052] The following is the method for applying adhesive to the annular connection between the cylindrical battery casing and the cap using the dispensing fixture 100:

[0053] First, the pre-assembled cylindrical outer shell and cap are fixed onto the cylindrical battery dispensing fixture 100 using the above method;

[0054] Then, align the glue gun nozzle with the connection between the cylindrical shell and the cap at the preset angle;

[0055] Finally, control the glue gun to continuously and stably dispense glue, and at the same time control the rotation drive 120 to drive the first fixing part 130 to rotate the semi-finished product one revolution, thus completing the glue dispensing.

[0056] Using the cylindrical battery dispensing fixture 100 for dispensing reduces operational difficulty, improves dispensing efficiency and uniformity, and ultimately enhances product quality compared to manually rotating the cylindrical casing and dispensing.

[0057] The cooperation between the guide rod 140 and the elastic element 160 ensures that the second fixing element 150 consistently provides thrust to the cylindrical outer shell, improving the clamping and fixing effect of the second fixing element 150 and the first fixing element 130 on the semi-finished product. Furthermore, it is applicable to cylindrical batteries of different lengths, exhibiting high versatility. Additionally, the first fixing element 130 of the cylindrical battery dispensing fixture 100 forms an "active wheel structure," and the second fixing element 150 forms a "driven wheel structure." Driven by the rotation drive element 120, it can reliably rotate the semi-finished product, improving the continuity and stability of the dispensing process. Moreover, circular dispensing can be achieved by controlling the rotation drive element 120, facilitating operation.

[0058] It is understandable that the rotation drive 120 is optional but not limited to a motor.

[0059] Further, see also Figure 1 and Figure 2 The base 110 is provided with a boss 111, and the boss 111 is provided with an arc-shaped support surface 1111. The arc-shaped support surface 1111 slides against the outer peripheral wall of the cylindrical shell. The arc-shaped support surface 1111 supports the cylindrical shell, which improves the reliability of the pre-assembled cylindrical shell and cap rotating around their own axis and helps to improve the uniformity of adhesive dispensing.

[0060] Optionally, see [link to relevant documentation] Figure 1 The cylindrical battery dispensing fixture 100 also includes a bearing 170. The other end of the guide rod 140 is connected to the inner ring of the bearing 170, and the outer ring of the bearing 170 is connected to the second fixing member 150. The bearing 170 enables a rotational connection between the second fixing member 150 and the guide rod 140, resulting in smoother rotation of the second fixing member 150. The structure is simple and easy to assemble.

[0061] Optionally, such as Figure 3 As shown, in one possible embodiment, the second fixing member 150 has a first groove 151 on the side opposite to the first fixing member 130, and the bearing 170 is installed in the first groove 151. The connection between the second fixing member 150 and the bearing 170 is achieved through the first groove 151, resulting in a simple structure that facilitates installation and disassembly. It is understood that, to ensure the reliability of synchronous rotation between the outer ring of the bearing 170 and the second fixing member 150, the outer ring of the bearing 170 can be interference-fitted with the peripheral wall of the first groove 151.

[0062] Optionally, such as Figure 4As shown, in one possible embodiment, the other end of the guide rod 140 is provided with two spaced-apart annular grooves 141, and the bearing 170 is located between the two annular grooves 141. A retaining ring 142 is installed in each annular groove 141, and the two retaining rings 142 are used to clamp and fix the bearing 170. By limiting the bearing 170 with the two retaining rings 142, the stability of the bearing 170 installation position is improved, and the structure is simple and convenient for the assembly of the bearing 170.

[0063] Further, see also Figure 1 In this embodiment, the elastic element 160 is sleeved on the guide rod 140, with one end of the elastic element 160 abutting against the base 110 and the other end abutting against the bearing 170. This arrangement allows the guide rod 140 to both drive the second fixing member 150 and mount the elastic element 160, eliminating the need for parts to fix the elastic element 160. This simplifies the structure of the cylindrical battery dispensing clamp 100 while improving the ease of installation of the elastic element 160.

[0064] It is understandable that the elastic element 160 is optional but not limited to a spring.

[0065] Optionally, see [link to relevant documentation] Figure 1 In one possible embodiment, the first fixing member 130 has a second groove 131 on the side near the second fixing member 150, the second groove 131 being used for insertion with the cap. It is understood that the shape of the second groove 131 matches the cap. Fixing the cap using the second groove 131 provides better fixation and facilitates the installation and removal of the cap.

[0066] Optionally, see [link to relevant documentation] Figure 2 In another possible embodiment, the second fixing member 150 has a third groove 152 on the side near the first fixing member 130. The third groove 152 is used for insertion into the cylindrical shell. Fixing the cylindrical shell through the third groove 152 provides a better fixing effect and facilitates the installation and removal of the cylindrical shell.

[0067] Further, see also Figure 1 and Figure 2The base 110 includes a base plate 101 and a first mounting seat 102 and a second mounting seat 103 disposed on the base plate 101. A rotation drive 120 is mounted on the first mounting seat 102, and a guide rod 140 is slidably mounted on the second mounting seat 103. The distance between the second mounting seat 103 and the first mounting seat 102 is adjustable. By making the distance between the second mounting seat 103 and the first mounting seat 102 adjustable, it is possible to make reasonable adjustments according to the size of the cylindrical battery, ensuring that the first fixing member 130 and the second fixing member 150 reliably clamp and fix the cylindrical shell and cap under the action of the elastic member 160, thus improving the working reliability of the cylindrical battery dispensing fixture 100. Furthermore, it also allows the cylindrical battery dispensing fixture 100 to be applied to cylindrical batteries of more sizes, improving its versatility.

[0068] Optionally, an elongated hole can be provided at the bottom of the second mounting base 103, through which a fastener passes and connects to the base plate 101. With this configuration, when it is necessary to adjust the distance between the second mounting base 103 and the first mounting base 102, the fastener can be loosened, the second mounting base 103 can be manually moved to the desired position, and then the fastener can be tightened. The structure is simple and the adjustment is convenient.

[0069] Optionally, see [link to relevant documentation] Figure 1 A guide sleeve 1031 can be installed on the second mounting base 103 so that one end of the guide rod 140 is slidably fitted onto the guide sleeve 1031 to improve the smoothness of the sliding of the guide rod 140.

[0070] Optionally, the guide sleeve 1031 can be a ball guide sleeve.

[0071] Example 2

[0072] This embodiment provides a dispensing device for cylindrical batteries, which can realize automatic dispensing between the cylindrical shell and the cap, further improving dispensing efficiency and uniformity, and reducing the labor intensity of workers.

[0073] Specifically, such as Figure 5 As shown, the dispensing equipment for cylindrical batteries includes a worktable 200, a dispensing mechanism 300, and a dispensing fixture 100 for cylindrical batteries provided in Embodiment 1.

[0074] In this embodiment, the cylindrical battery dispensing fixture 100 provided is mounted on the worktable 200. The dispensing mechanism 300 includes a lifting drive 310 and a dispensing unit 320. The lifting drive 310 is mounted on the worktable 200, and its output end is connected to the dispensing unit 320 to drive the dispensing unit 320 down to the connection between the cylindrical outer shell and the cap, so that the dispensing unit 320 dispenses adhesive at the connection between the cylindrical outer shell and the cap.

[0075] Of course, after the dispensing is completed, the lifting drive 310 will also control the dispensing unit 320 to rise, so that the dispensing unit 320 is away from the cylindrical shell and cap, so as to remove the assembled cylindrical shell and cap from the cylindrical battery dispensing fixture 100, and to facilitate the assembly of the pre-assembled accessories of the next cylindrical shell and cap to be dispensed onto the cylindrical battery dispensing fixture 100.

[0076] The dispensing equipment for cylindrical batteries provided in this embodiment uses the lifting drive component 310 and the rotation drive component 120 to control the automatic dispensing of cylindrical batteries, which greatly improves dispensing efficiency and dispensing quality.

[0077] Optionally, the lifting drive component 310 can be a cylinder, hydraulic cylinder, or other mechanism capable of outputting linear motion. It can be set according to actual needs, and this application does not make specific limitations.

[0078] Further, see also Figure 5 The worktable 200 is equipped with a support 210, and the support 210 is equipped with a slide 330. The slide 330 is equipped with a lifting drive 310, which drives the lifting drive 310 to move the dispensing unit 320 radially along the connection between the cylindrical shell and the cap. By setting the slide 330, the dispensing position of the dispensing unit 320 can be finely adjusted to ensure the reliability of dispensing.

[0079] Alternatively, in one possible embodiment, the support 210 is a "gantry" structure.

[0080] Optionally, see [link to relevant documentation] Figure 5 In one possible embodiment, the dispensing unit 320 may include a glue storage tank 321, a dispensing head 322, and a control valve (not shown in the figure). The dispensing head 322 is connected to the glue storage tank 321, and the control valve is used to control whether the dispensing head 322 dispenses glue. This dispensing unit 320 has a simple structure and is easy to control.

[0081] Optionally, a control panel 220 can also be installed on the worktable 200. The control panel 220 is equipped with a start button, an end button, and parameter information. The parameter information includes the rotation speed of the rotary drive 120, the lifting distance and lifting speed of the lifting drive 310, and the dispensing speed of the dispensing unit 320, etc.

[0082] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
