[0048] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0049] As described in the background art, the conventional burn-out furnace used for processing battery cells cannot remove the battery cells after they are dried or sintered.

[0050] Therefore, the present application creatively proposes a battery cell processing device, which includes a first processing mechanism, a second processing mechanism and a first loading and unloading mechanism. By arranging the first loading and unloading mechanism between the first processing mechanism and the second processing mechanism, the first loading and unloading mechanism is used to receive battery cells from the first processing mechanism for testing, so as to timely obtain various parameters of the battery cells being processed, and at the same time, the battery cells that pass the test are loaded to the second processing mechanism for further processing of the battery cells, and the battery cells that fail the test are temporarily stored.

[0051] The present application will be described in detail below through specific embodiments.

[0052] Reference Figures 1 to 6 As shown, the cell processing device includes a first processing mechanism 1, a second processing mechanism 2, and a first loading and unloading mechanism 3. The first processing mechanism 1 includes at least one drying furnace chamber 11 for drying the cell 8, and the second processing mechanism 2 includes at least one sintering furnace chamber 21 for sintering the cell 8. The first loading and unloading mechanism 3 for the cell 8 is located between the first processing mechanism 1 and the second processing mechanism 2. It is configured to receive the cell 8 from the first processing mechanism 1 for testing, to load the tested cell 8 to the second processing mechanism 2, and to temporarily store the unqualified cell 8 after testing.

[0053] It should be noted that Figure 1 Only part of the processing flow of the battery cell 8 is shown. The battery cell processing flow also includes steps such as annealing, which will not be repeated here.

[0054] The sintering treatment of the cell 8 refers to the sintering of the cell 8 to form an ohmic contact between the gate line on the cell 8 and the silicon substrate; the annealing treatment of the cell 8 is used to reduce the reduction in cell efficiency caused by the photodegradation effect.

[0055] It should be noted that the first processing mechanism 1 also includes two or more drying furnace chambers 11, and correspondingly, the second processing mechanism 2 includes the same number of sintering furnace chambers 21; and there are at least two ways to arrange the multiple drying furnace chambers 11 and the multiple sintering furnace chambers 21, which can be arranged as needed. For example, the first arrangement method is to arrange the multiple drying furnace chambers 11 and the multiple sintering furnace chambers 21 along the main conveying direction of the battery cell 8 (that is, the direction from the first processing mechanism 1 to the second processing mechanism 2), which means that the battery cell 8 first undergoes the same process (drying) multiple times in a row in the first processing mechanism 1, and then enters the second processing mechanism 2 through the processing of the first loading and unloading mechanism 3 to undergo the process (sintering) multiple times in a row. The second arrangement method: the number of drying furnace cavities 11 and sintering furnace cavities 21 is equal, and then multiple drying furnace cavities 11 are arranged in a direction perpendicular to the main conveying direction of the battery cells 8, and correspondingly, multiple sintering furnace cavities 21 are arranged in a direction perpendicular to the main conveying direction of the battery cells 8, and then the first loading and unloading mechanism 3 is placed between the multiple drying furnace cavities 11 and the multiple sintering furnace cavities 21, so that the battery cells 8 on multiple production lines can be processed at the same time.

[0056] It should be noted that, in the actual production process, the inspection of the battery cell 8 includes appearance inspection, electrical parameter inspection, etc., and the specific inspection purposes are also different. Users can choose according to actual needs. For example, the first type: only the appearance inspection of the battery cell 8 is performed, that is, the first loading and unloading mechanism 3 receives the battery cell 8 with damaged appearance in the first processing mechanism 1, and then inspects it, and loads the qualified battery cell 8 after the inspection to the second processing mechanism 2; the second type: only the electrical parameters of the battery cell 8 are inspected, that is, the first loading and unloading mechanism 3 receives the battery cell 8 processed by the first processing mechanism 1, and then inspects its electrical parameters, and then knows the processing quality of the battery cell 8 in the first processing mechanism 1, so as to make timely adjustments to the equipment parameters of the battery cell processing device in the future, and then load the qualified battery cell 8 after the inspection to the second processing mechanism 2 for further processing; the third type: both the appearance and electrical parameters of the battery cell 8 are inspected, which can not only remove the battery cell 8 with unqualified appearance in time to avoid the battery cell 8 with damaged appearance affecting other battery cells 8, but also adjust the equipment parameters of the battery cell processing device in time to ensure the processing quality of the battery cell 8.

[0057] It can be understood that when receiving and testing the battery cells 8, all the battery cells 8 flowing out of the first processing mechanism 1 can be tested, or some of the battery cells 8 can be extracted for testing. In order to take into account the overall processing efficiency of the battery cell processing device, in this embodiment, some of the battery cells 8 are randomly selected for testing according to certain principles; in addition, if the battery cell 8 is damaged in appearance, all damaged battery cells 8 need to be tested instead of randomly extracted.

[0058] Further, in some examples, reference Figure 2 and Figure 3 As shown, the first loading and unloading mechanism 3 includes a conveying component 31, a carrying platform 32 and a transporting component 33, wherein: the conveying component 31 has a conveyor belt 311 arranged along a first preset direction, the conveyor belt 311 is respectively docked with the discharge end of the first processing mechanism 1 and the feed end of the second processing mechanism 2, and is used to transport the battery cells 8; the carrying platform 32 is arranged on at least one side of the conveyor belt 311, and is used to carry the battery cells 8; the transporting component 33 includes a bracket 331, a transporting part 332 movable relative to the bracket 331, and a triggering part electrically connected to the transporting part 332, the triggering part is used to sense that the battery cell 8 to be detected reaches a predetermined position of the conveyor belt 311, and the transporting part 332 is used to transport the battery cell 8 to be detected from the conveyor belt 311 to the carrying platform 32 according to the signal of the triggering part.

[0059] It should be noted that the carrying platform 32 can store battery cells 8 that have passed the test, and temporarily store battery cells 8 that have failed the test.

[0060] Specifically, the first processing mechanism 1 and the second processing mechanism 2 are connected by the conveyor belt 311, so that the battery cell 8 is continuously conveyed in the main conveying direction, and sufficient working time is left for the conveying part 332 and the triggering part; when the battery cell 8 is transported to the predetermined position of the conveyor belt 311, the triggering part senses the battery cell 8 and transmits a signal to the conveying part 332. The conveying part 332 conveys the battery cell 8 to be inspected from the conveyor belt 311 to the supporting platform 32 according to the signal for inspection and to prevent the battery cell 8 to be inspected from affecting the normal operation of the conveyor belt 311.

[0061] In an alternative example, the transport component 33 may also be a multi-axis robotic arm, with a manipulator at the end of the robotic arm adapted to the battery cell 8 to grasp the battery cell 8. Of course, any other grasping mechanism that can grasp the battery cell 8 and move it within a certain range can be used as the transport component 33 in this application.

[0062] In another alternative example, referring to Figures 3 to 5As shown, the bracket 331 includes a sliding module 3311 arranged along a second preset direction and a mounting frame 3312 slidably connected to the sliding module 3311; wherein, the transporting portion 332 is at a preset distance from the transporting surface of the conveyor belt 311 to adsorb the battery cell 8 located on the conveyor belt 311; the second preset direction is parallel to the transporting surface of the conveyor belt 311 and is perpendicular to the first preset direction. Specifically, the second preset direction is on the same horizontal plane as the first preset direction and is perpendicular to the first preset direction, so that the battery cell 8 can be transported from the conveyor belt 311 while maintaining its placement direction (relative to the transporting direction of the conveyor belt 311), which facilitates the subsequent transportation and re-transportation of the battery cell 8 to the conveyor belt 311. In this example, the sliding mold is a linear sliding module 3311 such as a rodless cylinder.

[0063] Reference Figure 2 As shown in the figure, the X direction represents the first preset direction, and the Y direction represents the second preset direction.

[0064] In addition, it should be noted that there are many types of trigger units, which can be divided into automatic mode and manual mode according to the automatic type. In an alternative example, the trigger unit adopts an automatic mode, which is a detection camera or a photoelectric sensor. When the trigger unit senses that the battery cell 8 to be detected has reached the predetermined position of the conveyor belt 311, the trigger unit converts the detection signal into an electrical signal and sends it to the transport unit 332, so that the transport unit 332 can automatically transport the battery cell 8 to be detected from the conveyor belt 311 to the carrying platform 32. In another alternative example, the trigger unit adopts a manual mode, and the trigger unit includes a button and manual observation. When the human observes that the battery cell 8 has reached the predetermined position of the conveyor belt 311, the human presses a control element such as a button, so that the transport unit 332 transports the battery cell 8 to be detected from the conveyor belt 311 to the carrying platform 32.

[0065] Among them, the detection camera can be a PL camera, which is used to detect whether the battery cell 8 has hidden cracks (external damage); it can also be an AIO camera, which is used to detect the appearance of the battery cell 8 (external damage), or it can be a comprehensive detection camera, which detects at least one of hidden cracks or appearance, and the detection accuracy can be improved by the detection camera.

[0066] In some examples, in order to further distinguish the battery cells 8 transported by the transport unit 332, refer to Figure 2 and Figure 3As shown, a first area 321 and a second area 322 are provided on the carrying platform 32. The first area 321 is used to place the battery cells 8 to be inspected, and the second area 322 is used to place the battery cells 8 that have passed the inspection. The conveying part 332 is used to convey the battery cells 8 to be inspected from the conveyor belt 311 to the first area 321, and to convey the battery cells 8 that have passed the inspection from the second area 322 to the conveyor belt 311. Among them, when inspecting the appearance of the battery cell 8, if the appearance of the battery cell 8 is damaged, the battery cell 8 with damaged appearance can be temporarily placed in the first area 321, but a separate area can be divided within the first area 321 or on the carrying platform 32 to avoid confusing the battery cells 8 that have not been inspected with the battery cells 8 that have completed the inspection, and then the qualified battery cells 8 after the inspection are placed in the second area 322, so that the conveying part 332 can directly transport them from the second area 322 to avoid the situation of mistakenly transporting unqualified battery cells 8; at the same time, in some special cases, the staff can manually place the battery cells 8 (which have completed some preliminary processing) that have passed the inspection from other places directly in the second area 322 for transportation by the conveying part 332; at the same time, the staff can also directly take out the battery cells 8 with damaged appearance or other damage directly from the first area 321 for rejection, which will not affect the normal operation of the battery cell processing device.

[0067] It is understandable that, in order to increase the storage area of ​​the battery cells 8 , at least one carrying platform 32 may be provided on each side of the conveyor belt 311 in the width direction.

[0068] Further, in some examples, reference Figures 3 to 5 As shown, the first area 321 and / or the second area 322 are both provided with a transverse movement component 4, which includes a slide rail 41 and a support structure 42. The support structure 42 is used to place the battery cell 8 and is slidably connected to the slide rail 41 so that the support structure 42 with the battery cell 8 is close to or away from the conveyor belt 311; or, the first area 321 and / or the second area 322 are provided with a jacking component 5, which includes a driving member and a jacking structure 51 connected to the driving end of the driving member. The first area 321 and / or the second area 322 are provided with an avoidance hole for avoiding the jacking structure 51, and the driving member is used to drive the jacking structure 51 to move in the vertical direction and lift the battery cell 8 to a predetermined height.

[0069] In some examples, the support structure 42 is a material box for placing battery cells 8. When the number of damaged battery cells 8 on the support structure 42 reaches the upper limit of the capacity, the support structure 42 can be manually moved relative to the slide rail 41 to promptly remove the damaged battery cells 8, and then the empty support structure 42 can be returned to its original position to continue to place damaged battery cells 8 removed from the conveyor belt 311. In addition, the support structure 42 for placing qualified battery cells 8 can also be moved relative to the slide rail 41, away from the conveyor belt 311, and then qualified battery cells 8 transported from other places can be placed on the support structure 42 to replenish the qualified battery cells 8 for the battery processing device.

[0070] In addition, to facilitate the removal of the battery cells 8 and adjust the distance between the battery cells 8 on the lifting structure 51 and the transport portion 332, a driving member can be used to drive the lifting structure 51 to move in a vertical direction, thereby lifting the battery cells 8 to a predetermined height, so that the staff can promptly remove damaged battery cells 8 or replace qualified battery cells 8. In this embodiment, the lifting structure 51 can be placed on the support structure 42, and a clearance hole for the lifting structure 51 can be opened on the support structure 42 to improve the fit between the lifting structure 51 and the support structure 42. The lifting assembly 5 can also cooperate with the transport portion 332 to prevent the transport portion 332 from moving in the vertical direction or shorten the vertical movement path of the transport portion 332, thereby shortening the time it takes for the transport portion 332 to transport the battery cells 8 to the first area 321 and / or the second area 322. The driving member can be an electric cylinder, a pneumatic cylinder, or other drive source that can achieve linear drive.

[0071] In some examples, reference Figure 3 As shown, in order to increase the number of battery cells 8 transported per unit time, the first loading and unloading mechanism 3 can include at least two transport components 33, all of which are arranged at intervals along a first preset direction, and the transport components 33 include Bernoulli suction cups. The first preset direction is the conveying direction of the conveyor belt 311, which is also the main conveying direction of the battery cell processing device. Specifically, when the conveyor belt 311 starts to transport the battery cells 8, a number of predetermined positions equal to the number of transport components 33 can be set on the conveyor belt 311, so that when all the battery cells 8 can reach the predetermined positions at the same time, the corresponding transport components 33 are opened to transport the battery cells 8 at their corresponding preset positions. Alternatively, by controlling the distance between different predetermined positions, the same transport component 33 can be used to transport battery cells 8 at multiple predetermined positions within a certain period of time.

[0072] In some examples, reference Figure 3 and Figure 6As shown, a cooling assembly 6 is provided at the starting end of the conveyor belt 311 along the first preset direction. The cooling assembly 6 is used to cool the battery cells 8 on the conveyor belt 311. The cooling assembly 6 includes at least one fan 61 provided above the conveyor belt 311. The fan 61 is used to blow air to the battery cells 8 to lower the temperature of the battery cells 8 so as to cool the battery cells 8 that have been sintered, thereby facilitating subsequent processing of the battery cells 8.

[0073] In some examples, reference Figure 3 As shown, a tidying component 7 is provided at the end of the conveyor belt 311 along the first preset direction. The tidying component 7 includes two relatively arranged tidying pieces 71 and a driving piece. The two tidying pieces 71 move closer to or farther away from each other to tidy the battery cells 8, thereby adjusting the direction of the battery cells 8 that are deflected (relative to the main conveying direction of the device) during the processing process to facilitate subsequent conveying and processing of the battery cells 8.

[0074] In some examples, the cell processing device further includes a third processing mechanism, which is located after the second processing mechanism 2. The third processing mechanism includes a loading and conveying assembly, a transfer assembly, a conveying platform, an upper electrode module, a laser module, a unloading and conveying assembly, and an external power supply, wherein: the loading and conveying assembly is used to receive and convey the cell 8 output from the second processing mechanism 2; the transfer assembly is used to transport the cell 8 to be laser processed from the loading and conveying assembly to the conveying platform located at the loading station; the conveying platform is used to carry the cell 8 to be laser processed and deliver the cell 8 to be laser processed to the laser station, and to transfer the laser-processed cell 8 to the laser station. The cell 8 is sent to the unloading station; the upper electrode module is located at the laser station, one electrode of the external power supply is electrically connected to the front electrode of the cell 8 located at the laser station through the upper electrode module, and the other electrode of the external power supply is electrically connected to the back electrode of the cell 8 located at the laser station through the conveying platform; the external power supply is used to apply a reverse voltage to the cell 8 located at the laser station; the laser module is located above the laser station, and the laser module is used to perform laser scanning on the cell 8 after the external power supply applies a reverse voltage to the cell 8 located at the laser station. The transfer component is also used to transport the cell 8 that has completed laser processing from the conveying platform to the unloading conveying component.

[0075] It should be noted that laser processing can optimize the ohmic contact formed on the battery cell, thereby reducing the resistance of the battery cell and improving battery efficiency.

[0076] Furthermore, in some examples, the battery cell processing device also includes a second loading and unloading mechanism, which has the same structure as the first loading and unloading mechanism 3 and is arranged between the second processing mechanism 2 and the third processing mechanism.

[0077] Furthermore, in some examples, the cell processing apparatus further includes a fourth processing mechanism, which is located between the first processing mechanism 1 and the first loading and unloading mechanism 3. The third processing mechanism is used to illuminate the cell 8 using LEDs, and / or heat the cell 8, and / or cool the heated cell 8. The fourth processing mechanism is internally provided with the same loading and unloading conveying assembly and transfer assembly as the third processing mechanism to transfer the cell 8.
