Description

Technical Field

[0002] A battery cell is a single electrochemical cell containing a positive and negative electrode. It is the storage portion of a rechargeable battery, storing and releasing electrical energy. The battery cell must be weighed before and after filling to ensure that the weight meets standard requirements. This step is crucial to the production quality and subsequent performance of the battery cell.

[0003] The battery cell weighing device in the related art includes a support platform, a loading scale, a code scanning component, and a transfer component.

[0042] Figure 1 A schematic diagram of the structure of the battery cell weighing and code scanning device provided in this embodiment is shown at one viewing angle. Figure 2 A schematic structural diagram of the battery cell weighing and code scanning device provided in this embodiment is shown from another perspective. Figure 3 Shown Figure 2 A partial enlarged view at point A. Figure 1-Figure 3As shown, this embodiment provides a battery cell weighing and scanning device, which includes a carrier platform 100, a loading scale 200, a clamping assembly 300 and a positioning assembly 400; the loading scale 200 is arranged on the carrier platform 100; the clamping assembly 300 is arranged on the loading scale 200, and the clamping assembly 300 includes two clamping members 310 spaced apart along a first direction, and the distance between the two clamping members 310 is adjustable; the two positioning assemblies 400 are spaced apart along the second direction and are respectively located on both sides of the loading scale 200, and each positioning assembly 400 includes a pushing member 420 movable along the second direction; an accommodating space for accommodating a battery cell 10 to be weighed is formed between the two clamping members 310 and the two pushing members 420, and the bottom of the battery cell 10 to be weighed is supported on the loading scale 200.

[0043] It should be noted that in this embodiment, the first direction specifically refers to the width direction of the carrier platform 100, and the second direction specifically refers to the length direction of the carrier platform 100. In other embodiments, the two clamping members 310 may be spaced apart along the second direction, and the two positioning assemblies 400 may be spaced apart along the first direction, and this embodiment is not limited thereto.

[0044] It should be noted that this embodiment does not limit the specific structure of the loading scale 200, and all loading scales that can be used to weigh battery cells in the prior art are within the protection scope of this embodiment.

[0045] The battery cell weighing and scanning device provided in this embodiment can play the role of supporting the loading scale 200, the clamping assembly 300 and the positioning assembly 400 as a whole by providing a carrier platform 100, so as to ensure the structural compactness and stability of the entire battery cell weighing and scanning device; by providing the clamping assembly 300, the battery cell 10 to be weighed can be positioned along the first direction, and by providing the positioning assembly 400, the battery cell 10 to be weighed can be positioned along the second direction, thereby ensuring that the battery cell 10 to be weighed has an accurate placement position on the loading scale 200. The two-dimensional code set thereon can be accurately captured by the code scanning component, thereby improving the scanning accuracy of the battery cell 10 to be weighed, thereby improving the production efficiency and yield rate of the battery cell, and ensuring the safety of the finished battery cell; in addition, by setting the distance between the two clamping members 310 to be adjustable and the distance between the two ejecting members 420 to be adjustable, the size of the accommodating space for carrying the battery cell 10 to be weighed can be adjusted to match the battery cells 10 to be weighed of different models and sizes, thereby improving the versatility of the battery cell weighing and scanning device.

[0046] The steps of using the battery cell weighing and scanning device when weighing the battery cell 10 to be weighed are as follows: 1) adjusting the distance between the two clamping parts 310 and the distance between the two pushing parts 420 according to the model and size of the battery cell 10 to be weighed; at this time, the size of the accommodating space formed between the two clamping parts 310 and the two pushing parts 420 matches the size of the battery cell 10 to be weighed; 2) the transfer mechanism clamps the battery cell 10 to be weighed at the previous workstation and transfers it to the above-mentioned accommodating space; 3) the loading scale 200 can weigh the battery cell 10 to be weighed, and at the same time, the scanning component can scan and record the battery cell 10 to be weighed in the accommodating space.

[0047] It should be explained that since the size of the accommodating space is pre-adjusted, its size along the first direction and the size along the second direction should be slightly larger than the size of the battery cell 10 to be weighed along the first direction and the size along the second direction, respectively, to ensure that the battery cell 10 to be weighed can be smoothly inserted into the accommodating space, and to avoid damage caused by the edge of the battery cell 10 to be weighed colliding with the clamping member 310 or the pushing member 420.

[0048] It should be noted that this embodiment does not limit the specific structure of the transfer mechanism. The transfer mechanism can be a manipulator or a gripper with three-dimensional spatial movement function, both of which are relatively common devices in the prior art and will not be described in detail here. This embodiment does not limit the specific structure of the code scanning component. Any code scanning component in the prior art that can scan the QR code on the battery cell is within the scope of protection of this embodiment.

[0049] like Figure 2 and Figure 3 As shown, each positioning assembly 400 further includes a fixing member 430 and a positioning actuator 410. The positioning actuator 410 is connected to the support platform 100 via the fixing member 430. The output end of the positioning actuator 410 is connected to the corresponding ejection member 420 to drive the ejection member 420 to move in the second direction. The provision of the positioning actuator 410 enables automated position adjustment of the ejection member 420, reducing operator workload and labor costs. In this embodiment, the positioning actuator 410 is a drive cylinder, which has a simple structure, is easy to install, and is relatively low in cost.

[0050] Furthermore, the fixing member 430 is detachably connected to the carrier platform 100. This arrangement can realize the modular design of the entire positioning assembly 400, so that the positioning assembly 400 can be directly installed on the battery cell weighing and scanning device that does not have a positioning function in the prior art, thereby reducing production and improvement costs. Specifically, a first mounting hole is provided on the fixing member 430, and a second mounting hole corresponding to the first mounting hole is provided on the carrier platform 100. The fastener can be sequentially inserted into the first mounting hole and the second mounting hole, thereby realizing a detachable connection between the fixing member 430 and the carrier platform 100. The fastener is a bolt and nut assembly.

[0051] Optionally, the position of the fixing member 430 on the carrier 100 is adjustable, so that the installation position of the entire positioning assembly 400 on the carrier 100 can be adjusted according to the different models and sizes of the battery cells 10 to be weighed, thereby further improving the versatility of the battery cell weighing and scanning device. Specifically, in this embodiment, the first mounting hole is a strip-shaped mounting hole extending along the first direction, and the second mounting hole is a strip-shaped mounting hole extending along the second direction. The bolt of the fastener can pass through the strip-shaped mounting hole and the strip-shaped mounting hole in turn and then be tightened with the nut of the fastener, thereby achieving the effect of adjustable installation position of the fixing member 430 on the carrier 100. Of course, in other embodiments, the first mounting hole can also be set as a strip-shaped mounting hole extending along the second direction, and the second mounting hole can be set as a strip-shaped mounting hole extending along the first direction, which can also achieve the above-mentioned effect.

[0052] like Figure 2 As shown, the fixing member 430 is an L-shaped plate, which includes a horizontal plate 432 and a vertical plate 431 connected perpendicularly to each other. The side walls of the positioning driver 410 are connected to the vertical plate 431, and the bottom of the positioning driver 410 is connected to the horizontal plate 432. This arrangement can improve the stable connection between the fixing member 430 and the positioning driver 410, thereby ensuring the positioning effect of the positioning assembly 400 on the battery cell 10 to be weighed. In this embodiment, the horizontal plate 432 and the vertical plate 431 are an integrally formed structure, which can further improve the structural stability of the fixing member 430, save the links of assembling multiple parts with each other, and improve the processing efficiency of the fixing member 430. Optionally, the side walls and bottom of the positioning driver 410 are connected to the vertical plate 431 and the horizontal plate 432 of the fixing member 430 by screws, and the connection is stable and convenient for disassembly and assembly.

[0053] like Figure 2 and Figure 3As shown, the dimension of the ejector 420 along the first direction is larger than the dimension of the battery cell 10 to be weighed along the first direction, so that it can be used to position the battery cells 10 to be weighed of different thicknesses, so that the operator does not need to frequently replace the ejector 420 according to the different models of the battery cells 10 to be weighed, so as to reduce the workload of the operator. This setting can further improve the versatility of the entire battery cell weighing and scanning device. It should be explained that, in this embodiment, the above-mentioned "dimension of the battery cell 10 to be weighed along the first direction" refers to the thickness of the battery cell 10 to be weighed, and specifically refers to the maximum thickness of the battery cell 10 to be weighed in the prior art. Of course, in other embodiments, the above-mentioned "dimension of the battery cell 10 to be weighed along the first direction" can also refer to the maximum length or maximum width of the battery cell 10 to be weighed in the prior art. The operator can design the dimension of the ejector 420 along the first direction according to the placement direction of the battery cell 10 to be weighed in the accommodating space during the actual weighing operation, which is not limited here.

[0054] Optionally, a first fixing hole 421 is provided on the ejecting member 420, and a second fixing hole is provided on the output end of the positioning driver 410. The mounting member 440 is sequentially inserted into the first fixing hole 421 and the second fixing hole, thereby achieving a stable connection between the ejecting member 420 and the output end of the positioning driver 410. The mounting member 440 is a screw, and screw connection has the advantages of a secure connection and convenient operation. In this embodiment, the first fixing hole 421 is a bar-shaped hole extending along the first direction, that is, the connection position between the ejecting member 420 and the output end of the positioning driver 410 is adjustable, thereby further improving the versatility of the battery cell weighing and scanning device.

[0055] Continue as Figure 2 and Figure 3 As shown, the battery cell weighing and code scanning device further includes a support member 500, which is disposed on the loading scale 200. The two clamping members 310 of the clamping assembly 300 are both adjustable along the first direction and disposed on the support member 500. The provision of the support member 500 enables a modular design of the clamping assembly 300, allowing the clamping assembly 300 and the support member 500 to be directly installed on a battery cell weighing and code scanning device that only has a loading scale 200 in the prior art, thereby reducing production and improvement costs.

[0056] Furthermore, the clamping assembly 300 includes a locking member 320. Each clamping member 310 is provided with a strip-shaped adjustment hole 311 extending along the first direction. The support member 500 is provided with a connecting hole corresponding to each clamping member 310. The locking member 320 can pass through the strip-shaped adjustment hole 311 and connect to the connecting hole, thereby adjusting the position of the clamping member 310 on the support member 500. The locking member 320 is a locking screw, and screw connection has the advantages of a secure connection and convenient operation.

[0057] It should be explained that, in this embodiment, the locking member 320 can be sequentially provided on the clamping member 310, the support member 500 and the loading scale 200 to achieve a stable connection between the clamping member 310 and the support member 500 and between the support member 500 and the loading scale 200. This arrangement can omit the provision of some screws, thereby simplifying the assembly process, improving assembly efficiency, and reducing production costs to a certain extent. Of course, in other embodiments, a locking member 320 can also be provided to connect the clamping member 310 and the support member 500, and additional connecting screws can be provided to connect the support member 500 and the loading scale 200. This arrangement can also achieve the above-mentioned effect.

[0058] Optionally, the number of the bar-shaped adjustment holes 311 on each clamping member 310 is at least two, and the at least two bar-shaped adjustment holes 311 are spaced apart along the second direction, and each bar-shaped adjustment hole 311 corresponds to a connecting hole and a locking member 320. This arrangement prevents the clamping member 310 from rotating around the locking member 320, thereby ensuring the accuracy of the spacing adjustment between the two clamping members 310. In this embodiment, the number of the bar-shaped adjustment holes 311 on each clamping member 310 is two to simplify the processing process and improve processing efficiency. Of course, in other embodiments, the number of the bar-shaped adjustment holes 311 on each clamping member 310 can also be three, four, five, six, or even more, which is not limited here.

[0059] like Figure 3 As shown, the top of the clamping member 310 is tilted away from the accommodating space to facilitate the insertion of the battery cell 10 to be weighed into the accommodating space, preventing the edge of the battery cell 10 to be weighed from colliding or rubbing with the top of the clamping member 310, thereby preventing the battery cell 10 to be weighed from being damaged, thereby ensuring the appearance integrity of the battery cell 10 to be weighed and the quality of the finished product.

[0060] Continue as Figure 1 and Figure 2 As shown, in this embodiment, the number of clamping assemblies 300 is at least two, and the at least two clamping assemblies 300 are spaced apart along the second direction, thereby ensuring that the clamping assemblies 300 can stably clamp the battery cell 10 to be weighed along the first direction. In this embodiment, the number of clamping assemblies 300 is two, so as to achieve a stable clamping effect while reducing the number of clamping assemblies 300, thereby reducing the processing cost of the battery cell weighing and scanning device. Of course, in other embodiments, the number of clamping assemblies 300 can also be three, four, five, six, or even more, which is not limited here.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the scope of protection of the present invention.
