Description

Technical Field

[0001] This application relates to the field of assembly technology, specifically to a positioning device. Background Technology

[0002] When assembling cylindrical lithium-ion batteries into battery packs, a spot welding machine is typically used to connect the positive and negative terminals of multiple individual battery cells to achieve parallel or series connections. Parallel connections increase the battery pack's capacity, while series connections increase its voltage. Before assembling and welding multiple cylindrical lithium-ion batteries, a positioning device is used to arrange and fix the individual battery cells, facilitating the welding process.

[0003] In related technologies, the positioning device only serves to support multiple battery cells. Before welding, the battery cells need to be manually arranged sequentially on the positioning device. After welding, the welded battery pack needs to be manually removed from the positioning device. Because manual intervention is required throughout the entire processing, the processing efficiency of the battery pack is low. Utility Model Content

The bottom end of each through slot is connected to the inlet of the discharge pipe, wherein the size of the inlet of the discharge pipe is adapted to the size of a single battery cell.

[0027] Optionally, the body portion further includes a third sidewall and a fourth sidewall disposed opposite to each other, as well as a first guide wall and a second guide wall disposed opposite to each other;

Detailed Implementation

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0053] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0054] Combination Figure 1 , Figure 2 and Figure 3As shown in the figure, this application provides a positioning device, which includes a storage component 100, a positioning component 200, a first driving component 300, and a support base 400.

[0055] The storage unit 100 has a storage tank 101 and a discharge port 102, the storage tank 101 and the discharge port 102 are connected, and the storage tank 101 contains a plurality of battery cells 500. It should be noted that the battery cells 500 in this embodiment can be, for example, cylindrical battery cells 500. The plurality of battery cells 500 can be stacked in the height direction within the storage tank 101.

[0056] The positioning assembly 200 includes a support plate 201, a storage component 100 mounted on the first end of the support plate 201, and a discharge port 102 located above the support plate 201 and facing the second end of the support plate 201 opposite to the first end. With this configuration, multiple battery cells 500 in the storage tank 101 can automatically fall onto the support plate 201 through the discharge port 102, and then be processed on the support plate 201 for welding and other operations. Since manual loading is unnecessary, the processing efficiency of the battery pack can be improved.

[0057] The support base 400 is rotatably connected to the carrier plate 201. The driving end of the first driving member 300 is connected to the carrier plate 201. The first driving member 300 is used to drive the carrier plate 201 to rotate relative to the support base 400, so that the second end of the carrier plate 201 is lower than the first end or to keep the carrier plate 201 horizontal. It can be understood that when multiple battery cells 500 need to be welded and assembled on the carrier plate 201, the first driving member 300 can be used to drive the carrier plate 201 to rotate to a horizontal position to prevent the batteries from slipping off the carrier plate 201, thereby ensuring that multiple battery cells 500 can be welded and processed on the carrier plate 201. After multiple battery cells 500 are welded and assembled into a battery pack, the first driving component 300 can drive the support plate 201 so that the second end of the support plate 201 is lower than the first end of the support plate 201. At this time, the support plate 201 is tilted, so that the multiple battery cells 500 assembled into the battery pack can slide off the second end of the tilted support plate 201 under their own weight and fall into the designated battery pack storage area to complete the unloading.

[0058] As can be seen from the above, by using the positioning device provided in the embodiments of this application, when welding and assembling multiple battery cells 500, the positioning device can automatically perform loading and unloading without manual intervention, thereby simplifying the operation and greatly improving the processing efficiency of the battery pack.

[0059] The following is in conjunction with the appendix Figures 1 to 8 The details and functions of the positioning device provided in the embodiments of this application will be described in more specific and detailed manner.

[0060] In some embodiments, the positioning component 200 further includes a first baffle 202 and a second baffle 203 disposed opposite to each other, with both sides of the support plate 201 connected to the first baffle 202 and the second baffle 203 respectively. It should be noted that the first baffle 202 and the second baffle 203 can limit the two sides of the battery cell 500, preventing the battery cell 500 from falling off the sides of the support plate 201. In some embodiments, both ends of the battery cell 500 can abut against the first baffle 202 and the second baffle 203 respectively, thereby ensuring that multiple battery cells 500 on the support plate 201 are arranged side-by-side in the direction from the first end to the second end of the support plate 201.

[0061] like Figure 3 As shown, in some embodiments, the first baffle 202 is provided with a plurality of first slots 204, and the second baffle 203 is provided with a plurality of second slots (not shown in the figure), with the first slots 204 and the second slots corresponding one-to-one. The positioning component 200 also includes a third baffle 206, the two ends of which are respectively engaged with the corresponding first slots 204 and the corresponding second slots. It should be noted that the plurality of first slots 204 are arranged side by side in the extending direction of the support plate 201, and the plurality of second slots are arranged side by side in the extending direction of the support plate 201. By engaging the third baffle 206 into the first slots 204 and the second slots, the battery cell 500 can be blocked, preventing the battery cell 500 from slipping off the second end of the support plate 201 before processing is completed. It should be understood that after multiple battery cells 500 are welded, the third baffle 206 can be separated from the first slot 204 and the second slot, so that when the support plate 201 is tilted, the battery pack can be automatically slid from the second end of the support plate 201 to the designated storage area to complete the automatic unloading process.

[0062] Combination Figure 3 and Figure 5As shown, in some embodiments, the positioning assembly 200 further includes a second driving member 207 and a fourth baffle 208. One side of the fourth baffle 208 abuts against the second end face of the support plate 201. The driving end of the second driving member 207 is connected to the fourth baffle 208, and the second driving member 207 is used to drive the fourth baffle 208 to move up and down between a first position and a second position. It should be noted that the number of second driving members 207 can be one, two, or more. The fourth baffle 208 can further block the battery cell 500, preventing the battery cell 500 from sliding off the second end of the support plate 201 before it is fully processed. In addition, a first receiving area can be formed between the third baffle 206 and the fourth baffle 208, and a second receiving area can be formed between the third baffle 206 and the storage member 100. The first receiving area can accommodate multiple battery cells 500 that have been welded into a battery pack, and the second receiving area can accommodate multiple battery packs that have not been fully welded. This configuration allows for the separate storage of welded and unwelded battery cells 500 using the first and second accommodating areas, preventing duplicate processing or omissions. It should be understood that when welding multiple battery cells 500 is required, the second drive member 207 can drive the fourth baffle 208 to rise until its bottom end face is flush with the lower surface of the support plate 201, preventing the battery cells 500 from slipping. When the welding operation of the battery cells 500 is completed, the second drive member 207 can drive the fourth baffle 208 to descend until its top end is flush with or below the upper surface of the support plate 201. Thus, when the first drive member 300 drives the support plate 201 to an inclined position, the battery pack can automatically fall off the support plate 201 under gravity, completing the unloading process. In some embodiments, the fixed end of the second drive member 207 can be mounted on the ground or other fixed supports.

[0063] Combination Figure 3 and Figure 4 As shown, in some embodiments, the support base 400 includes a first limiting plate 401 and a second limiting plate 402 disposed opposite to each other, as well as at least two first support columns 403 and at least two second support columns 404, with the first support columns 403 and the second support columns 404 corresponding one-to-one and disposed opposite to each other. The first limiting plate 401 abuts against the side of the first baffle 202 opposite to the second baffle 203 and is rotatably connected to the first baffle 202. The second limiting plate 402 abuts against the side of the second baffle 203 opposite to the first baffle 202 and is rotatably connected to the second baffle 203. It should be noted that the first limiting plate 401 and the first baffle 202 can be rotatably connected by a pin, and the second limiting plate 402 and the second baffle 203 can also be connected by a pin. The first limiting plate 401 and the second limiting plate 402 can respectively provide support and guidance for the first baffle 202 and the second baffle 203.

[0064] One end of the first support column 403 is connected to the first limiting plate 401, and the other end is adapted to abut against the target platform. One end of the second support column 404 is connected to the second limiting plate 402, and the other end is adapted to abut against the target platform. It should be noted that the target platform in this embodiment can be, for example, the ground. The first support column 403 and the second support column 404 support the bearing plate 201 and the storage component 100 respectively through the first limiting plate 401 and the second limiting plate 402. In some embodiments, the fixed end of the first driving member 300 can be installed on the first limiting plate 401 or the second limiting plate 402. It should be noted that the first driving member 300 and the second driving member 207 in this embodiment can both be, for example, drive motors.

[0065] Combination Figure 3 and Figure 4 As shown, in some embodiments, the support base 400 further includes a reinforcing plate 405, the two ends of which are connected to the first limiting plate 401 and the second limiting plate 402, respectively. The distance between the reinforcing plate 405 and the plane containing the bearing plate 201 is not less than the diameter of the battery cell 500. It should be noted that the reinforcing plate 405 can further improve the strength of the support base 400, thereby improving the stability of the positioning assembly 200.

[0066] like Figure 6 As shown, in some embodiments, the storage component 100 includes a body portion 103 and a discharge pipe 104. The body portion 103 is provided with a storage tank 101. One end of the discharge pipe 104 is connected to the bottom end of the body portion 103, and the other end is mounted on a support plate 201. A discharge port 102 is provided on the side of the discharge pipe 104 facing the second end of the support plate 201. It should be understood that the battery cells 500 in the storage tank 101 can fall sequentially from the discharge end of the storage tank 101 into the discharge pipe 104, and then fall onto the support plate 201 through the discharge port 102.

[0067] Combination Figure 1 , Figure 7 and Figure 8As shown, in some embodiments, the main body 103 includes a first sidewall 105 and a second sidewall 106 disposed opposite to each other. The storage component 100 also includes a plurality of partition plates 107, the two sides of which are connected to the first sidewall 105 and the second sidewall 106 respectively, to divide the storage tank 101 into a plurality of parallel through slots 108. The bottom end of each through slot 108 is connected to the inlet of the discharge pipe 104, wherein the size of the inlet of the discharge pipe 104 is adapted to the size of a single battery cell 500. It should be noted that a plurality of battery cells 500 are stacked in each through slot 108 to achieve storage of the battery cells 500. This configuration allows the battery cells 500 to fall one by one into the discharge pipe 104, and then one by one from the discharge port 102 of the discharge pipe 104 onto the support plate 201. This avoids problems such as multiple battery cells 500 falling into the discharge pipe 104 at the same time, which could cause blockage of the discharge port 102 of the discharge pipe 104, thus ensuring the smoothness of the feeding process.

[0068] Combination Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, the body portion 103 further includes a third sidewall 109 and a fourth sidewall 110 disposed opposite to each other, and a first guide wall 111 and a second guide wall 112 disposed opposite to each other. The two sides of the third sidewall 109 are connected to the first sidewall 105 and the second sidewall 106, respectively. The two sides of the fourth sidewall 110 are connected to the first sidewall 105 and the second sidewall 106, respectively. Both the third sidewall 109 and the fourth sidewall 110 are parallel to the partition plate 107. The first side of the first guide wall 111 is connected to the third sidewall 109, and the second side is connected to the first side of the discharge pipe 104. The first guide wall 111 has an inclined surface, and the second side of the first guide wall 111 is lower than the first side. The first side of the second guide wall 112 is connected to the fourth sidewall 110, and the second side is connected to the second side of the discharge pipe 104. The second guide wall 112 has an inclined surface, and the second side of the second guide wall 112 is lower than the first side. It should be understood that the first guide wall 111 and the second guide wall 112 can guide the movement direction of the battery cell 500, ensuring that the battery cell 500 can be guided to the inlet of the discharge pipe 104, and then fall from the outlet 102 of the discharge pipe 104 onto the support plate 201.

[0069] Combination Figure 7 and Figure 8 As shown, in some embodiments, the distance between the first guide wall 111 and the bottom end of each partition plate 107 is not less than the diameter of the battery cell 500. The distance between the second guide wall 112 and the bottom end of each partition plate 107 is not less than the diameter of the battery cell 500. This arrangement ensures that the battery cell 500 will not be stuck between the partition plate 107 and the first guide wall 111 or the second guide wall 112, thus ensuring smooth feeding.
