Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a detection device and battery processing equipment. Background Art

[0002] After the battery cell is manufactured, it is necessary to conduct an appearance inspection on the battery cell to ensure that the quality of the battery cell used to assemble the battery or battery module is qualified. However, when conducting an appearance inspection on the electrode terminal of the battery cell, since the side area of ​​the electrode terminal is small and each electrode terminal has four sides, and the setting direction of each side is different, there are problems such as a relatively complex inspection structure and a long inspection time, which affects the inspection efficiency of the battery cell. Utility Model Content

[0003] Based on this, it is necessary to provide a detection device and battery processing equipment to address the problem that the detection structure is relatively complex and the detection time is long when performing appearance inspection on the side of the electrode terminal, which affects the detection efficiency of the battery cell.

[0004] In a first aspect, the present application also provides a detection device, comprising:

[0005] A reflector having a reflective channel, an inner wall of the reflective channel having a reflective surface, the reflective channel is used to accommodate at least part of the electrode terminals of the battery cell, and the reflective surface is used to reflect light from the electrode terminals to form reflective information; and

[0006] The detection member is used to obtain reflection information of the reflection surface and detect the appearance of the electrode terminal based on the reflection information.

[0007] Through the above structure, the reflective component is covered on the electrode terminal of the battery cell so that at least a part of the electrode terminal is located in the reflective channel. Thus, the reflective surface in the reflective channel can reflect each side surface of the electrode terminal at the same time and transmit the reflected information to the detection component, thereby detecting multiple side surfaces of the electrode terminal at the same time, effectively improving the detection efficiency.

[0008] In some embodiments, the reflective surface includes four sub-surfaces, each sub-surface is arranged to intersect with the sub-surface adjacent to it, and all the sub-surfaces are enclosed to form a reflective channel.

[0009] Through the above structure, each sub-surface can reflect a corresponding side surface, so that the appearance information of multiple sides can be collected simultaneously and fed back to the detection part for unified detection, thereby improving the detection efficiency and simplifying the detection structure.

[0010] In some embodiments, each sub-surface is arranged at an angle to the axis of the reflection channel, and the inner diameter of the reflection channel gradually increases from one end close to the electrode terminal to the other end along its own axis.

[0011] Thus, through the inclined sub-surfaces, each side surface can be smoothly reflected to the detection member, so that the detection member can take a picture of the side surface imaging, thereby detecting the appearance information of each side surface and improving the detection efficiency.

[0012] In some embodiments, the detection device further includes a base and a connecting member, the reflector is disposed on the connecting member, and the connecting member is movably disposed on the base along a horizontal direction to adjust the position between the reflector and the electrode terminal along a horizontal direction.

[0013] Therefore, through the above structure, the position of the connecting member and the reflector thereon relative to the battery cell in the horizontal direction can be adjusted, so that the reflector can better cover the electrode terminal of the battery cell for easy detection.

[0014] In some embodiments, a first slide rail extending in a horizontal direction is provided on one of the base and the connecting member, and a first slide groove slidably matched with the first slide rail is provided on the other of the base and the connecting member.

[0015] With the above structure, the reflective member can be driven to move in the horizontal direction by the connecting member, so as to adjust the distance between the reflective member and the battery cell, so that the reflective member can be better covered on the electrode terminal.

[0016] In some embodiments, the reflective member is movably disposed on the connecting member along the vertical direction to adjust the position between the reflective member and the electrode terminal along the vertical direction.

[0017] Therefore, through the above structure, the position of the reflector relative to the electrode terminal in the vertical direction can be better adjusted, so that the reflector can be smoothly covered on the electrode terminal to reflect the side of the electrode terminal.

[0018] In some embodiments, one of the connecting member and the reflecting member is provided with a second slide rail extending in the vertical direction, and the other of the connecting member and the reflecting member is provided with a second slide groove slidably matched with the second slide rail.

[0019] Through the above structure, the reflector can be moved in the vertical direction to adjust the distance between the reflector and the battery cell, so that the reflector can be better covered on the electrode terminal.

[0020] In some embodiments, the reflector further comprises a base, a reflective body, and an adjusting cylinder connected between the base and the reflective body, wherein the adjusting cylinder is used to adjust the position of the reflective body in the vertical direction;

[0021] Wherein, the reflection channel is formed inside the reflection body.

[0022] When the reflective body cover is arranged on the electrode terminal, the position of the reflective body in the vertical direction is precisely adjusted by adjusting the cylinder, so that the electrode terminal can be better positioned in the reflective channel, and the reflective surface can reflect each side surface, making the reflected side surface more complete and improving the detection quality.

[0023] In some embodiments, the reflective members include two and are arranged at intervals in the horizontal direction, and each reflective member is used to cover a corresponding electrode terminal on the battery cell.

[0024] Therefore, through the above structure, it is possible to simultaneously detect the positive electrode terminal and the negative electrode terminal side of the battery cell, thereby improving the detection efficiency.

[0025] In a second aspect, the present application also provides a battery processing device, comprising the detection device as described above, the detection device being used to detect the side appearance of the electrode terminal of the battery cell.

[0026] In some embodiments, the battery processing equipment further includes a conveying member for conveying battery cells, and the detection device is disposed on at least one side of the conveying member to detect the side surfaces of the electrode terminals of the battery cells on the conveying member.

[0027] In the above-mentioned detection device and battery processing equipment, at least part of the electrode terminals of the battery cell are accommodated in the reflection channel, so that the reflection surface in the reflection channel can reflect each side of the electrode terminal at the same time, and transmit the reflection information to the detection component, thereby detecting multiple sides of the electrode terminal at the same time, effectively improving the detection efficiency.

[0037] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0038] The battery is composed of one or more battery cells. For each battery, the battery cells that make up the battery can be connected in series, in parallel, or in mixed connection. Mixed connection means that the battery cells are connected in series and in parallel.

[0039] Multiple battery cells can be directly assembled into a battery, or they can be assembled into a battery module first, and then assembled into a battery through one or more battery modules. However, before assembling a battery or a battery module from battery cells, it is necessary to conduct an appearance inspection on each outer surface of the battery cells to ensure that the appearance quality of the battery cells is qualified.

[0040] In the structure of the battery cell, each electrode terminal has multiple sides, and the setting directions of each side are different. At present, when performing appearance inspection on the side of the electrode terminal, it is necessary to set up multiple inspection parts, and each inspection part corresponds to the appearance inspection of one of the sides. As a result, the overall structure of the inspection device is relatively complex, which increases the production cost. In addition, each inspection part needs to perform the inspection operation separately and needs to be debugged separately, which increases the inspection time and affects the inspection efficiency.

[0041] Based on the above considerations, in order to solve the problem that when performing appearance inspection on the side of the electrode terminal, the inspection structure is relatively complex and the inspection time is long, which affects the inspection efficiency of the battery cell, a detection device is provided in one or more embodiments of the present application, wherein at least part of the electrode terminals of the battery cell are accommodated in a reflection channel, so that the reflection surface in the reflection channel can reflect each side of the electrode terminal at the same time, and transmit the reflection information to the detection component, thereby simultaneously inspecting multiple sides of the electrode terminal, effectively improving the detection efficiency.

[0042] See also Figure 1 and Figure 2 An embodiment of the present application provides a detection device 100, including a reflector 10 and a detection member 20. The reflector 10 has a reflection channel 11. The inner wall of the reflection channel 11 has a reflection surface 12. The reflection channel 11 is used to accommodate at least part of the electrode terminal 201 of the battery cell 200. The reflection surface 12 is used to reflect light from the electrode terminal 201 to form reflection information. The detection member 20 is used to obtain the reflection information of the reflection surface 12, and detect the appearance of the electrode terminal based on the reflection information.

[0043] It should be noted that the detection device 100 can be used to detect the side of the electrode terminal 201 on the battery cell 200. The electrode terminal 201 can be a pole structure protruding from the top cover of the battery cell 200, and the electrode terminal 201 has multiple sides, each of which intersects with the upper surface of the top cover. When the electrode terminal 201 is set as a rectangular structure, each electrode terminal 201 has four sides, and the four sides are perpendicular to the upper surface of the top cover.

[0044] At present, when inspecting the appearance of a battery cell 200, it is necessary to inspect each outer surface of the battery cell 200. However, the side surface area of ​​the electrode terminal 201 is small, and the setting direction of each side surface is different. In this regard, it is usually necessary to set up multiple inspection mechanisms, each of which is set toward a corresponding side surface of the electrode terminal 201 and inspects the side surface of the electrode terminal 201.

[0045] Based on this, the current detection structure for the side of the electrode terminal 201 is relatively complex, and the installation and debugging process of multiple detection mechanisms is also relatively complex and time-consuming, which increases the overall operational difficulty of the appearance inspection of the battery cell 200, and the operation cost is high and the operation efficiency is low.

[0046] In this regard, the present application provides a detection device 100, including a reflector 10 and a detection member 20, wherein the reflector 10 refers to a structure capable of reflecting each side surface of an electrode terminal 201, so that appearance information of the sides of multiple electrode terminals 201 can be uniformly received or uniformly processed. The detection member 20 refers to a structure capable of receiving appearance information of the sides of multiple electrode terminals 201 reflected by a reflective surface 12, and detecting the appearance of each side surface.

[0047] Specifically, a reflective channel 11 is provided inside the reflector 10, the reflective channel 11 is hollow and has openings at both ends, and the inner wall of the reflective channel 11 is configured as a reflective surface 12. The reflector 10 can be covered on the electrode terminal 201 of the battery cell 200. When the reflector 10 is covered on the electrode terminal 201, at least part of the electrode terminal 201 is located in the reflective channel 11. At this time, the reflective surface 12 is arranged toward the electrode terminal 201, and the appearance information of the side of the electrode terminal 201 can be detected.

[0048] Furthermore, the detection component 20 may include but is not limited to a light source and a CCD camera (Charge coupled Device). When detecting the side of the electrode terminal 201, light is first emitted to the side so that the reflective surface 12 can reflect the side of the electrode terminal 201. At this time, the CCD camera captures the side image reflected by the reflective surface 12 and transmits it to the host computer. The host computer can analyze and judge the captured content, thereby obtaining the detection result of the side of the electrode terminal 201.

[0049] Through the above structure, the reflective element 10 is covered on the electrode terminal 201 of the battery cell 200, so that at least a part of the electrode terminal 201 is located in the reflective channel 11. Therefore, the reflective surface 12 in the reflective channel 11 can reflect each side surface of the electrode terminal 201 at the same time, and transmit the reflection information to the detection element 20, so as to detect multiple sides of the electrode terminal 201 at the same time, effectively improving the detection efficiency.

[0050] In some embodiments, the reflective surface 12 includes four sub-surfaces 13 , each sub-surface 13 is arranged to intersect with the sub-surface 13 adjacent thereto, and all the sub-surfaces 13 enclose and form a reflective channel 11 .

[0051] Specifically, the electrode terminal 201 is usually configured as a rectangular structure, that is, the electrode terminal 201 has four sides. Therefore, the reflective surface 12 can be configured as four sub-surfaces 13, and each sub-surface 13 is perpendicular to the adjacent sub-surface 13, that is, the four sub-surfaces 13 together enclose a quadrilateral reflective channel 11.

[0052] When the reflector 10 is covered on the electrode terminal 201, the four sub-surfaces 13 correspond to the four side surfaces of the electrode terminal 201 respectively, and each sub-surface 13 reflects the appearance information of the corresponding side surface to the detection element 20. Thus, the four sub-surfaces 13 simultaneously reflect the appearance information of the corresponding side surface, so that the appearance information of the four side surfaces is simultaneously transmitted to the detection element 20, and the detection element 20 simultaneously detects the appearance information of the four side surfaces, thereby effectively improving the detection efficiency.

[0053] In addition, it can be understood that when the electrode terminal 201 is set to other structures, each sub-surface 13 is set to correspond to each side of the electrode terminal 201. That is, when the electrode terminal 201 is set to a triangular prism structure, the reflective surface 12 includes three sub-surfaces 13, and is set to correspond to the three side surfaces. Thus, each sub-surface 13 can reflect a side surface, thereby collecting the appearance information of multiple side surfaces at the same time, and feeding it back to the detection member 20, thereby improving the detection efficiency.

[0054] Through the above structure, each sub-surface 13 can reflect a corresponding side surface, so that appearance information of multiple side surfaces can be collected simultaneously and fed back to the detection element 20 for unified detection, thereby improving detection efficiency and simplifying the detection structure.

[0055] In some embodiments, each sub-surface 13 is arranged at an angle to the axis of the reflection channel 11 , and the inner diameter of the reflection channel 11 gradually increases from one end close to the electrode terminal 201 to the other end along its own axis.

[0056] Specifically, when the reflector 10 is covered on the electrode terminal 201, the inner diameter of the reflective channel 11 gradually increases from the end close to the electrode terminal 201 to the end away from the electrode terminal 201. That is, the reflective channel 11 is constructed as a trapezoidal structure.

[0057] Furthermore, the detection member 20 is disposed on a side of the reflection channel 11 away from the electrode terminal 201. Thus, when the reflection member 10 is covered on the electrode terminal 201, each side surface is reflected and imaged through each inclined sub-surface 13, so that the detection member 20 can smoothly capture the reflected side image and detect it.

[0058] Therefore, through the inclined sub-surface 13, each side surface can be smoothly reflected to the detection member 20, so that the detection member 20 can take a picture of the side surface imaging, thereby detecting the appearance information of each side surface and improving the detection efficiency.

[0059] In some embodiments, the detection device 100 further includes a base 30 and a connector 40 , the reflector 10 is disposed on the connector 40 , and the connector 40 is movably disposed on the base 30 along a horizontal direction to adjust the position between the reflector 10 and the electrode terminal 201 along a horizontal direction.

[0060] It should be noted that, in order to improve the production efficiency of the battery cell 200, the appearance inspection of the battery cell 200 is usually performed when the battery cell 200 is completed and transferred to the next process. At this time, the battery cell 200 is transported from the previous process to the next process on the conveyor, and the inspection device 100 can be set between the two processes.

[0061] When the battery cell 200 moves to a position corresponding to the detection device 100 , the battery cell 200 may be controlled to stop moving. At this time, the detection device 100 performs an appearance inspection on the battery cell 200 .

[0062] Specifically, the connecting member 40 is movably arranged on the base 30 along the conveying direction of the battery cell 200, and the reflecting member 10 is arranged on the connecting member 40, so that the connecting member 40 can drive the reflecting member 10 to move relative to the battery cell 200 along the conveying direction of the battery cell 200, thereby adjusting the relative position between the reflecting member 10 and the battery cell 200.

[0063] Thus, through the above structure, the position of the connector 40 and the reflector 10 thereon relative to the battery cell 200 in the horizontal direction can be adjusted, so that the reflector 10 can be better covered on the electrode terminal 201 of the battery cell 200 for easy detection.

[0064] In some embodiments, a first slide rail 31 extending in the horizontal direction is provided on one of the base 30 and the connector 40 , and a first slide groove 41 slidably matched with the first slide rail 31 is provided on the other of the base 30 and the connector 40 .

[0065] Specifically, a first slide rail 31 may be extended along the horizontal direction on the base 30, and a first slide groove 41 slidably matched with the first slide rail 31 may be provided on the connecting member 40. In this way, the connecting member 40 can achieve relative movement with the base 30 by sliding the first slide groove 41 on the first slide rail 31, so that the reflector 10 can be movably arranged in the horizontal direction.

[0066] Of course, in some other embodiments, a first slide rail 31 extending in the horizontal direction may be provided on the connecting member 40, and a first slide groove 41 slidably matched with the first slide rail 31 may be provided on the base 30, so as to realize relative movement between the base 30 and the connecting member 40, which will not be elaborated here.

[0067] With the above structure, the reflector 10 can be driven to move in the horizontal direction by the connecting member 40 to adjust the distance between the reflector 10 and the battery cell 200 so that the reflector 10 can be better covered on the electrode terminal 201 .

[0068] In some embodiments, the reflector 10 is movably disposed on the connector 40 along the vertical direction to adjust the position between the reflector 10 and the electrode terminal 201 along the vertical direction.

[0069] It should be noted that different specifications of battery cells 200 have different sizes, such as different heights, different widths, different thicknesses, etc. When it is necessary to perform appearance inspection on battery cells 200 of different heights, in order to better adapt to the height of each battery cell 200, it is necessary to adjust the position of the reflector 10 in the vertical direction so that the reflector 10 can be smoothly covered on the electrode terminal 201 for easy inspection.

[0070] Therefore, through the above structure, the position of the reflector 10 relative to the electrode terminal 201 in the vertical direction can be better adjusted, so that the reflector 10 can be smoothly covered on the electrode terminal 201 to reflect the side of the electrode terminal 201.

[0071] In some embodiments, a second slide rail 42 extending in the vertical direction is disposed on one of the connecting member 40 and the reflecting member 10 , and a second slide groove 14 slidably matched with the second slide rail 42 is disposed on the other of the connecting member 40 and the reflecting member 10 .

[0072] Specifically, a second slide rail 42 may be extended along the vertical direction on the connecting member 40, and a second slide groove 14 slidably matched with the second slide rail 42 may be provided on the reflecting member 10. In this way, the reflecting member 10 can achieve relative movement with the connecting member 40 through the sliding of the second slide groove 14 on the second slide rail 42, so that the reflecting member 10 is movably arranged in the vertical direction.

[0073] Of course, in some other embodiments, a second slide rail 42 extending in the vertical direction may be provided in the vertical direction, and a second slide groove 14 slidably matched with the second slide rail 42 may be provided on the connecting member 40, so as to realize the relative movement between the reflector 10 and the connecting member 40, which will not be elaborated here.

[0074] Through the above structure, the reflector 10 is movable in the vertical direction to adjust the distance between the reflector 10 and the battery cell 200 , so that the reflector 10 can be better covered on the electrode terminal 201 .

[0075] In some embodiments, the reflector 10 further includes a base 15, a reflective body 16, and an adjustment cylinder 17 connected between the base 15 and the reflective body 16, wherein the adjustment cylinder 17 is used to adjust the vertical position of the reflective body 16. The reflective channel 11 is formed inside the reflective body 16.

[0076] Specifically, the base 15 can provide a mounting base for the reflective body 16 and the adjusting cylinder 17 , and can also achieve connection and fixation with the connecting member 40 .

[0077] The reflection channel 11 is formed inside the reflection body 16 , that is, the reflection body 16 is used to cover the electrode terminal 201 and reflect the side surface of the electrode terminal 201 through the reflection surface 12 .

[0078] The adjusting cylinder 17 is connected between the base 15 and the reflecting body 16 . The reflecting body 16 is driven to move in the vertical direction by the telescopic movement of the adjusting cylinder 17 , thereby adjusting the position of the reflecting body 16 relative to the electrode terminal 201 .

[0079] When the reflective body 16 is covered on the electrode terminal 201, the position of the reflective body 16 in the vertical direction can be precisely adjusted by adjusting the cylinder 17, so that the electrode terminal 201 can be better located in the reflective channel 11, and the reflective surface 12 can reflect each side surface, making the reflected side surface more complete, thereby improving the detection quality.

[0080] In some embodiments, two reflective members 10 are provided and spaced apart in the horizontal direction, and each reflective member 10 is used to cover a corresponding electrode terminal 201 on the battery cell 200 .

[0081] The battery cell 200 is provided with a positive electrode terminal and a negative electrode terminal. By providing two reflectors 10 , each reflector 10 is correspondingly covered on one electrode terminal 201 , so that the sides of the positive electrode terminal 201 and the negative electrode terminal 201 are detected respectively.

[0082] Therefore, through the above structure, it is possible to simultaneously detect the positive electrode terminal and the negative electrode terminal side of the battery cell 200, thereby improving the detection efficiency.

[0083] Based on the same concept as the above-mentioned detection device 100 , the present application also provides a battery processing device, including the above-mentioned detection device 100 , which is used to detect the side appearance of the electrode terminal 201 of the battery cell 200 .

[0084] In some embodiments, the battery processing equipment further includes a conveyor for conveying the battery cells 200 , and the detection device 100 is disposed on at least one side of the conveyor to detect the side surfaces of the electrode terminals 201 of the battery cells 200 on the conveyor.

[0085] Specifically, the conveyor may be, but is not limited to, a conveyor belt or a conveyor roller. Placing the battery cell 200 on the conveyor may drive the battery cell 200 to move from a previous process to a next process, so as to continuously process the battery cell 200.

[0086] Among them, the detection device 100 is arranged on at least one side of the conveying member. When the conveying member drives the battery cell 200 to move from the previous process to the next process, the conveying member can be controlled to temporarily stop the battery cell 200 at a position corresponding to the detection device 100, so as to facilitate the detection of the appearance of the battery cell 200 by the detection device 100.

[0087] According to one or more embodiments, the battery cell 200 is first transported by the conveyor, and when the battery cell 200 moves to a position corresponding to the detection device 100, the conveyor is controlled to stop. At this time, the connecting member 40 is controlled to move relative to the base 30 in the horizontal direction to drive the reflecting member 10 on the connecting member 40 to move in the horizontal direction, thereby adjusting the relative position between the reflecting member 10 and the battery cell 200 in the horizontal direction, so that the reflecting member 10 is located directly above the electrode terminal 201.

[0088] Furthermore, the reflector 10 is controlled to move in the vertical direction so that the reflector 10 can cover the corresponding electrode terminal 201. Then, the position of the reflector body 16 in the vertical direction is further adjusted by adjusting the cylinder 17 so that the electrode terminal 201 can be better located in the reflective channel 11, and each reflective surface 12 can completely reflect the appearance of the corresponding side surface.

[0089] The reflective surface 12 transmits the reflected images of each side surface to the detection component 20 , and the detection component 20 takes a picture of the reflected images and transmits them to the host computer. The host computer analyzes and determines the received information to realize the detection of the side surface of the electrode terminal 201 .

[0090] Of course, since the detection component 20 is arranged directly above the electrode terminal 201, when the reflective surface 12 reflects the appearance information of each side surface, the detection component 20 can directly capture the appearance image of the top surface of the electrode terminal 201 from top to bottom, thereby simultaneously inspecting the top surface of the electrode terminal 201, completing the overall appearance inspection of the electrode terminal 201, and improving the inspection efficiency.

[0091] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
