In the current photovoltaic cell production process, inspection is only carried out once on the conveying mechanism, which results in substandard cells not being identified, leading to quality problems in the subsequently produced cell strings.
A dual detection mechanism is adopted, which performs preliminary and secondary detection on the battery cell pack through a first detection mechanism above the conveying mechanism and a second detection mechanism above the carrying mechanism. Substandard battery cells are automatically rejected by the first and second handling mechanisms, and qualified battery cells rejected from the previous process are replenished by the feeding mechanism.
This effectively reduced the rate of missed detections, ensuring that substandard battery cells were detected and dealt with in a timely manner, improving product quality, increasing production efficiency and operational safety, while also realizing the recycling of resources and reducing production costs.

Abstract
Description
Technical Field
[0001] This application relates to the technical field of solar cell processing, and more specifically, to a solar cell feeding device. Background Technology
[0002] In the production process of photovoltaic cells, cell inspection is a crucial step in ensuring product quality. Existing production processes typically involve a conveyor system that transports several cells sequentially to the unloading station. An inspection station is located upstream of the unloading station on the conveyor system. Cameras or other inspection devices at the inspection station perform quality checks on the cells passing through it. If a cell fails to meet the standards, it is removed by a rejection mechanism. The compliant cells are then transported to the unloading station by the conveyor system, and subsequently, a handling mechanism moves the cells from the unloading station to a carrying mechanism for temporary storage.
[0003] However, the inventors of this application discovered that even if the battery cells are only inspected once on the conveying mechanism, there will still be substandard battery cells that are not identified, resulting in quality problems in the battery strings produced subsequently. Utility Model Content
[0004] To solve the above-mentioned technical problems, this application provides a battery cell feeding device, which adopts the following technical solution:
[0005] A battery cell feeding device includes a conveying mechanism, a feeding mechanism, a carrying mechanism, a first detection mechanism, a second detection mechanism, a waste collection mechanism, a first handling mechanism, and a second handling mechanism, wherein:
[0006] The conveying mechanism is configured to receive at least one set of battery cell groups at a first position and convey at least one set of battery cell groups to a second position, each set of battery cell groups comprising a first battery cell and a second battery cell arranged in sequence.
[0007] The first testing mechanism is mounted above the conveying mechanism and located between the first position and the second position. The first testing mechanism is configured to determine whether the first and second battery cells in each battery cell group on the conveying mechanism meet the standards.
[0008] The first conveying mechanism is configured to pick up at least one set of battery cell packs from the conveying mechanism at the second position and place each picked-up battery cell pack on the carrying mechanism;
[0009] The second testing mechanism is installed above the support mechanism. The second testing mechanism is configured to determine whether the first and second cells in each battery cell group on the support mechanism meet the standards.
[0010] The second conveying mechanism is configured to pick up the substandard first and second battery cells on the carrying mechanism and send them to the waste collection mechanism, which is located between the feeding mechanism and the carrying mechanism.
[0011] The feeding mechanism is configured to supply qualified first and second solar cells;
[0012] After the substandard first battery cell is removed from the carrier mechanism, the second conveying mechanism is also configured to pick up the first battery cell from the feeding mechanism and release the picked-up first battery cell into the empty position created on the carrier mechanism after the substandard first battery cell is removed.
[0013] After the substandard second cell is removed from the carrier mechanism, the second conveying mechanism is also configured to pick up the second cell from the feeding mechanism and release the picked-up second cell into the empty position created by the removal of the substandard second cell on the carrier mechanism.
[0014] This application provides a solar cell replenishment device that integrates a conveying mechanism, a feeding mechanism, a carrying mechanism, a first / second detection mechanism, and a first / second handling mechanism to achieve fully automated detection, rejection, and replenishment of solar cells. The first detection mechanism, located above the conveying mechanism, is used for preliminary detection of whether the first and second solar cells in the solar cell group meet the standards. The second detection mechanism, located above the carrying mechanism, is used for secondary detection of the solar cell group on the carrying mechanism. This dual detection mechanism effectively reduces the missed detection rate, ensures that substandard solar cells are detected and processed in a timely manner, and improves product quality.
[0015] The device can automatically determine whether the first and second battery cells on the carrier mechanism meet the standards through the second detection mechanism, and remove the substandard first and second battery cells through the second conveying mechanism. At the same time, it selects the qualified first or second battery cells from the feeding mechanism to fill the corresponding empty positions on the carrier mechanism. The whole process does not require manual intervention, which significantly improves production efficiency and operational safety.
[0016] In addition, the source of the patch material from the feeding mechanism is qualified battery cells that have been rejected in the previous process. This not only reduces the tedious operation of regular manual feeding, but also realizes the recycling of resources and reduces production costs.
[0017] Optionally, the feeding mechanism includes a first conveying track, a first storage component and a second storage component. The first storage component and the second storage component are sequentially mounted on the first conveying track. The first storage component is used to store the first qualified battery cell, and the second storage component is used to store the second qualified battery cell. The first conveying track is sequentially provided with a first feeding position, a second feeding position and a replenishment position.
[0018] After the second inspection agency detects that there is a substandard first battery cell on the carrier mechanism, the first storage component is configured to release the stored first battery cell on the first feeding position, and the first conveying track is configured to convey the first battery cell released on the first feeding position to the replenishment station.
[0019] After the second inspection mechanism detects that there is a substandard second battery cell on the carrier mechanism, the second storage component is configured to release the stored second battery cell onto the second feeding position, and the first conveying track is configured to convey the second battery cell released onto the second feeding position to the replenishment station.
[0020] The second handling mechanism is configured to pick up either the first or second battery cell at the replenishment station on the first conveying track.
[0021] The first and second storage components are used to store compliant first and second solar cells, respectively, avoiding material mixing issues and improving replenishment accuracy. The first conveyor track can transport compliant first / second solar cells from the first / second feeding station to the replenishment station, realizing automated feeding, reducing manual intervention, and improving feeding efficiency. The second handling mechanism can pick up the first or second solar cell at the replenishment station and fill the vacant position on the carrying mechanism after the removal of non-compliant first or second solar cells.
[0022] Optionally, the first storage component includes a hopper and a first drive unit, and the first storage component is configured to release qualified first battery cells sequentially from bottom to top, wherein:
[0023] The hopper includes a base, a first hopper plate, and a second hopper plate. The first hopper plate and the second hopper plate are installed on opposite sides of the base. The inner sidewall of the first hopper plate is provided with multiple first support members arranged parallel from top to bottom and spaced apart. The inner sidewall of the second hopper plate is provided with second support members that correspond one-to-one with each of the first support members. Each first support member and its corresponding second support member are arranged opposite each other in the same horizontal plane to jointly support a first battery cell.
[0024] The hopper straddles the first conveying track. The two ends of the first battery cell protrude from the first conveying track along the width direction of the first conveying track. The distance between each first support member and the corresponding second support member is greater than the width of the first conveying track and less than the length of the first battery cell.
[0025] The first drive unit is configured to drive the hopper to descend step by step, so that the first battery cell stored at the bottom of the hopper descends to the first feeding position on the first conveying track.
[0026] The structure of the second storage component may be the same as or different from that of the first storage component.
[0027] The hopper in the first storage component ensures the stable storage and orderly release of compliant first solar cells, preventing damage during storage and feeding. The distance between the first support and its corresponding second support is greater than the width of the first conveyor track to prevent interference. The distance between the first support and its corresponding second support is less than the length of the first solar cell, allowing them to work together to support the first solar cell and prevent it from falling. The first drive unit drives the hopper to descend stepwise, lowering the lowest compliant first solar cell stored in the hopper to the first feeding position on the first conveyor track. The first solar cell at the first feeding position is then conveyed to the replenishment station along the first conveyor track, achieving automated feeding of compliant first solar cells. The structure of the second storage component may be the same as or different from that of the first storage component, enabling stable storage and orderly release of compliant second solar cells.
[0028] Optionally, a first sizing station is provided on the first conveying track in front of the feeding station, and a first sizing component is provided on the side of the first sizing station.

[0031] The first alignment component can align the first or second battery cell, achieving automated alignment and reducing positional deviations of the first or second battery cell. The automated alignment of the first alignment component can make the position of the first or second battery cell more accurate when it enters the replenishment station, so that the first or second battery cell located at the replenishment station can be picked up more accurately by the second conveying mechanism, thereby improving the quality and efficiency of replenishment.
[0032] Optionally, the feeding mechanism also includes a lifting and rotating assembly, the first conveying track being two parallel and spaced conveyor belts, and the lifting and rotating assembly being disposed between the two conveyor belts;

The limiting structure on the receiving component can stop the first or second battery cell on the receiving surface of the receiving component. The second driving component can drive the receiving component to lift vertically and / or rotate horizontally. After the receiving component is lifted to a preset height, the first or second battery cell located on the receiving component can be removed from the first conveying track. Then, the receiving component rotates horizontally by a preset angle, thereby driving the first or second battery cell located on the receiving component to rotate, so that the orientation of the first or second battery cell located on the receiving component meets the formulation requirements, improving compatibility.

[0042] The temporary storage component is located on the side of the temporary storage station and is used to replace the carrier to carry several sets of battery cells that have been moved to the temporary storage station.
[0043] By setting up a carrier component, a second sizing component, and a temporary storage component, the second sizing component first sizes the first half of the battery cell string carried by the carrier component. The first half of the battery cell string includes several groups of battery cells. Then, the carrier component transfers the sizing first half of the battery cell string to the temporary storage component for temporary storage. Subsequently, the carrier component receives the second half of the battery cell string from the next batch, sizes it, and moves it to the side of the temporary storage component, so as to form a well-arranged battery cell string on the temporary storage component and the carrier component. The second half of the battery cell string includes several groups of battery cells.
[0044] Optionally, the second alignment component includes a second alignment drive and two second alignment components symmetrically arranged on both sides of the second alignment station;
[0045] When the carrier component moves several sets of battery cells to the second straightening station, the second straightening drive drives at least one second straightening component to move closer to the carrier component in order to straighten the several sets of battery cells from both sides.
[0046] The second alignment drive drives at least one second alignment component to move closer to the carrier component, thereby automating the alignment process, reducing manual intervention, and improving alignment efficiency. The aligned battery cell pack can be more accurately replaced by the temporary storage component, thus improving the quality and efficiency of temporary storage.

In the first pick-up assembly of the first transport mechanism, several adsorption elements are mounted on a sliding beam. A third drive element drives the sliding beam forward or backward along the conveying direction of the conveying mechanism to adjust the position of each adsorption element. This allows the first pick-up assembly to adapt to battery cell packs of different sizes and to pick up battery cell packs with positional deviations.
[0062] Optionally, the second conveying mechanism includes a second mounting bracket, a second drive assembly, and an adsorption assembly, wherein:

[0070] The feed mechanism sources its replacement cells from the qualified solar cells rejected in the previous process. In the previous process, solar cell packs are transported by a conveyor, and a first inspection mechanism determines whether the cells meet the standards. A rejection mechanism sends non-compliant cells to a storage mechanism, while a compliant cell pack is fed into the feed mechanism. This operation reduces the tedious manual, periodic feeding process, achieves resource recycling, and lowers production costs.

[0121] The device can automatically determine whether the first and second battery cells on the carrier mechanism 3 meet the standards through the second detection mechanism, and remove the substandard first and second battery cells through the second conveying mechanism 7. At the same time, it selects the qualified first or second battery cells from the feeding mechanism 2 to fill the corresponding empty positions on the carrier mechanism 3.

[0135] The nth first support member 2211 and the corresponding nth second support member 2212 (set opposite to each other in the same horizontal plane) are taken as the nth group of support members, 1≤n≤i, and n is a positive integer;
[0136] The first storage component 22 releases qualified first battery cells sequentially from bottom to top;
[0137] The first driving component 222 drives the hopper 221, which stores several qualified first battery cells, to descend, so that the upper surface of the bottom i-th group of support members is lower than the conveying surface of the first conveying track 21, and the i-th first battery cell descends to the first feeding position of the first conveying track 21; then, the i-th first battery cell that has descended to the first feeding position will be conveyed to the replenishment station along the first conveying track 21.
[0138] Subsequently, the first drive unit 222 lowers the first storage component 22 to a specified height H, so that the (i-1)th group of support members arrives at the position of the i-th group of support members, and so that the (i-1)th first battery cell descends to the first feeding position of the first conveying track 21; then, the (i-1)th first battery cell that has descended to the first feeding position will be conveyed to the replenishment station along the first conveying track 21.
[0139] Repeat the descent action of the first storage component 22 (the first storage component 22 descends a specified height H each time) until the first battery cell on the first set of supports also descends to the first feeding position of the first conveying track 21, which means that the first battery cell stored in the first storage component 22 has been released.
[0140] When the structure of the second storage component 23 is the same as that of the first storage component 22, the working process of the second storage component 23 in the second inspection process can be referred to the above description of the working process of the first storage component 22, except that the second storage component 23 releases a qualified second battery cell in the second inspection process.
[0141] The hopper 221 in the first storage component 22 ensures the stable storage and orderly release of qualified first solar cells, preventing damage during storage and feeding. The distance between the first support member 2211 and the corresponding second support member 2212 is greater than the width of the first conveying track 21 to prevent interference. The distance between the first support member 2211 and the corresponding second support member 2212 is less than the length of the first solar cell, allowing them to work together to support the first solar cell and prevent it from falling. The first drive member 222 drives the hopper 221 to descend step by step, allowing the lowest qualified first solar cell stored in the hopper 221 to fall to the first feeding position on the first conveying track 21. Then, the first solar cell that has fallen to the first feeding position is conveyed to the replenishment station along the first conveying track 21, realizing automated feeding of qualified first solar cells. The structure of the second storage component 23 may be the same as or different from that of the first storage component 22, and it can achieve stable storage and orderly release of the qualified second battery cells.

The first alignment drive drives at least one first alignment component to move closer to the first conveying track 21, shortening the distance between the two first alignment components, thereby limiting the position of the first or second battery cell in the conveying direction perpendicular to the first conveying track 21. The automated alignment of the first alignment component 24 can make the position of the first or second battery cell more accurate when it enters the replenishment station, so that the first or second battery cell located at the replenishment station can be picked up more accurately by the second conveying mechanism 7, thereby improving the quality and efficiency of replenishment.

After the receiving member 252 is raised to a preset height, the first or second battery cell located on the receiving member 252 can be separated from the first conveying track 21. Then, the receiving member 252 rotates horizontally by a preset angle, thereby driving the first or second battery cell located on the receiving member 252 to rotate, so that the orientation of the first or second battery cell located on the receiving member 252 meets the formulation requirements and improves compatibility.

In the second testing process, the cell replenishment device of this application places at least one cell group on the conveying mechanism 1 on the carrier mechanism 3 and uses the second testing mechanism to test the cells in each cell group on the carrier mechanism 3. Then, the second transport mechanism 7 picks up the first and second cells that do not meet the standards on the carrier mechanism 3 and sends them to the waste collection mechanism 5. Next, the second transport mechanism 7 picks up the first / second cells that meet the standards from the feeding mechanism 2 and releases the picked-up first / second cells on the carrier mechanism 3 to fill the empty positions created after the removal of the first / second cells that did not meet the standards.
[0202] For ease of understanding, the first and second inspection processes involved in the battery cell feeding device of this application are explained below by way of example:
[0203] 1. First inspection step:
[0204] like Figure 10-11 As shown, this process involves a conveying mechanism 1, a first detection mechanism 4, a storage mechanism 8, a feeding mechanism 2, and a rejection mechanism 9;
[0205] The conveying mechanism 1 is configured to receive at least one set of battery cell groups at a first position and convey at least one set of battery cell groups to a second position. Each set of battery cell groups includes a pair of battery cells, which are a first battery cell and a second battery cell arranged in sequence. For example, on the conveying mechanism 1, there are first battery cells, second battery cells, first battery cells, second battery cells, first battery cells, second battery cells, first battery cells, second battery cells, second battery cells, first battery cells, second battery cells, and so on.
[0206] The first detection mechanism 4 is mounted above the conveying mechanism 1 and located between the first position and the second position. The first detection mechanism 4 is configured to determine whether the first and second battery cells in each battery cell group on the conveying mechanism 1 meet the standards. A battery cell group in which both the first and second battery cells meet the standards is a normal battery cell group. A battery cell group in which the first and / or second battery cells do not meet the standards is an abnormal battery cell group. That is to say, if any one of the first and second battery cells in the battery cell group does not meet the standards or both do not meet the standards, then the battery cell group is an abnormal battery cell group.
[0207] The storage mechanism 8 and the feeding mechanism 2 are located on both sides of the conveying mechanism 1. The storage mechanism 8 is used to store the first and second substandard battery cells in each abnormal battery cell group detected by the first detection mechanism 4. The feeding mechanism 2 is used to store the first and second standard battery cells in each abnormal battery cell group.
[0208] The rejection mechanism 9 is mounted above the conveying mechanism 1. The rejection mechanism 9 is located between the first detection mechanism 4 and the second position. The rejection mechanism 9 includes a mounting frame 91 and a third drive assembly 92 and a second pickup assembly 93 mounted on the mounting frame 91. The second pickup assembly 93 is configured to pick up non-compliant battery cells in the abnormal battery cell group on the conveying mechanism 1, as well as compliant battery cells in the abnormal battery cell group.
[0209] The third drive assembly 92 is configured to drive the second pick-up assembly 93 to move between the feeding mechanism 2, the conveying mechanism 1, and the storage mechanism 8, so that the second pick-up assembly 93 feeds the substandard battery cells into the storage mechanism 8 and feeds the compliant battery cells in the battery cell group into the feeding mechanism 2, wherein the compliant first battery cell and the compliant second battery cell are stored separately in the feeding mechanism 2.
[0210] The replenishment source of the cells in the feeding mechanism 2 is the qualified cells rejected in the first inspection process. In the first inspection process, the cell group is transported by the conveying mechanism 1, and the first inspection mechanism 4 determines whether the cells meet the standards. The rejection mechanism 9 sends the unqualified cells to the storage mechanism 8, and sends the qualified cells in the cell group to the feeding mechanism 2. The qualified cells rejected by the rejection mechanism 9 will be continuously replenished into the feeding mechanism 2, thereby reducing the tedious operation of manual periodic feeding, realizing the recycling of resources, and reducing production costs.
[0211] Optionally, the conveying mechanism 1 is configured to move one group of battery cells (first battery cell and second battery cell) at a time along the direction from the first position to the second position; that is, the distance moved each time is the total length of one group of battery cells (first battery cell and second battery cell).
[0212] Optionally, the distance from the feeding mechanism 2 to the conveying mechanism 1 is the same as the distance from the storage mechanism 8 to the conveying mechanism 1. The second picking component 93 includes a first picker 931 and a second picker 932, which are used to pick up the first battery cell and the second battery cell, respectively.

The first pickup 931 is slidably mounted on the first guide rail, and the second pickup 932 is slidably mounted on the second guide rail.
[0214] The third drive assembly 92 includes a timing belt 921 and a fourth drive member. The timing belt 921 is horizontally mounted on the mounting bracket 91. The fourth drive member is drivenly connected to the timing belt 921. The first pickup 931 and the second pickup 932 are respectively fixedly connected to the two sides of the timing belt 921. The fourth drive member is configured to drive the timing belt 921 to rotate so that the first pickup 931 and the second pickup 932 move in opposite directions.
[0215] The feeding mechanism 2 and the storage mechanism 8 are at the same distance from the conveying mechanism 1, making the movement path of the second picking component 93 symmetrical, thus improving the stability and efficiency of the operation. The first picker 931 and the second picker 932 are used to pick up the first battery cell and the second battery cell respectively, realizing the simultaneous processing of different battery cells. The first picker 931 and the second picker 932 are fixedly connected to the two sides of the synchronous belt 921 respectively, realizing the synchronous reverse movement of the first picker 931 and the second picker 932, thus improving the coordination and efficiency of the operation.
[0216] Optionally, the fourth drive component 922 can be selected by those skilled in the art according to production needs; for example, a servo motor can be selected.
[0217] Optional, such as Figure 10 As shown, the storage mechanism 8 includes a first material box and a second material box arranged side by side. The first picker 931 is configured to move the first non-compliant battery cell in the abnormal battery cell group to the first material box and release it in the first material box; the second picker 932 is configured to move the second non-compliant battery cell in the abnormal battery cell group to the second material box and release it in the second material box.
[0218] Optional, such as Figure 11 As shown, the first pickup 931 includes a first support frame and a fifth drive member and a first pickup member disposed on the first support frame. The first support frame is slidably mounted on a first guide rail. The fifth drive member is configured to drive the first pickup member to lift and lower. The first pickup member is configured to adsorb or release the first battery cell.
[0219] The second pickup 932 includes a second support frame, a sixth drive member and a second pickup member disposed on the second support frame. The second support frame is slidably mounted on a second guide rail. The sixth drive member is configured to drive the second pickup member to lift and lower. The second pickup member is configured to adsorb or release the second battery cell.
[0220] The first pickup 931 uses a first pickup element to pick up or release the first battery cell, and the second pickup 932 uses a second pickup element to pick up or release the second battery cell. The first pickup 931 and the second pickup 932 have a clear division of labor and a compact structure, which is suitable for picking up or releasing the first battery cell and the second battery cell in a limited space. Furthermore, the first guide rail can support the weight of the first pickup 931 and provide guidance, and the second guide rail can support the weight of the second pickup 932 and provide guidance.
[0221] Optionally, the initial positions of the first pickup 931 and the second pickup 932 are located side by side directly above the conveying mechanism 1. Those skilled in the art can adjust the distance between the first pickup 931 and the second pickup 932 according to actual production needs, so that the first pickup 931 and the second pickup 932 can pick up one of the two paired battery cells in the battery cell group directly below.
[0222] For example, the operation of the first pickup 931 and the second pickup 932 can be as follows:
[0223] When the first detection mechanism 4 detects that the battery cell group located directly below the first picker 931 and the second picker 932 on the conveying mechanism 1 is an abnormal battery cell group, and only one of the two battery cells in the abnormal battery cell group meets the standard while the other does not, the first picker 931 and the second picker 932 descend and pick up one of the two battery cells directly below. The first picker 931 moves the non-compliant battery cell forward along the second direction to directly above the storage mechanism 8, while the second picker 932 simultaneously moves the compliant battery cell backward along the second direction to above the feeding mechanism 2. The first picker 931 and the second picker 932 descend and release the battery cell, and then the first picker 931 and the second picker 932 reset to their initial positions.
[0224] When the first detection mechanism 4 detects that the battery cell group located directly below the first picker 931 and the second picker 932 on the conveying mechanism 1 is an abnormal battery cell group, and both battery cells in the abnormal battery cell group are substandard, the first picker 931 and the second picker 932 pick up one battery cell from the abnormal battery cell group respectively. The first picker 931 first puts the substandard battery cell into the storage mechanism 8, and then moves in the opposite direction to above the feeding mechanism 2, so that the second picker 932 moves above the storage mechanism 8 and performs the feeding action. Then the first picker 931 and the second picker 932 return to their initial positions.
[0225] Optionally, the first pickup member is provided with at least one first adsorption structure, and the second pickup member is provided with at least one second adsorption structure; the first adsorption structure and the second adsorption structure are suction cups or adsorption holes.

The first storage component 22 and the second storage component 23 are sequentially mounted on the first conveying track 21. The first storage component 22 is used to store qualified first battery cells, and the second storage component 23 is used to store qualified second battery cells. The first conveying track 21 is sequentially provided with a loading position, a first feeding position, and a second feeding position. The first storage component 22 is located at the first feeding position, and the second storage component 23 is located at the second feeding position.
[0232] The second picking component 93 is configured to move and release the first qualified battery cell in the abnormal battery cell group to the loading position, and the first conveying track 21 is configured to convey the first battery cell at the loading position to the first storage component 22 at the first feeding position.
[0233] The second picking component 93 is configured to move and release the qualified second cell in the abnormal cell group to the loading position, and the first conveying track 21 is configured to convey the second cell at the loading position to the second storage component 23 at the second feeding position.
[0234] Through the cooperation of the first conveying track 21 and the first / second storage component 23, the automatic storage of qualified first / second solar cells is achieved, reducing manual intervention; the qualified first / second solar cells stored by the first / second storage component 23 can still be reused.
[0235] Optional, such as Figure 9-10 As shown, the first storage component 22 includes a hopper 221 and a first drive unit 222. The first storage component 22 is configured to receive qualified first battery cells sequentially from top to bottom, wherein:
[0236] The hopper 221 includes a base, a first hopper plate, and a second hopper plate. The first hopper plate and the second hopper plate are installed on opposite sides of the base. The inner sidewall of the first hopper plate is provided with a plurality of first support members 2211 arranged parallel from top to bottom and spaced apart. The inner sidewall of the second hopper plate is provided with second support members 2212 that correspond one-to-one with each of the first support members 2211. Each first support member 2211 and the corresponding second support member 2212 are arranged opposite each other in the same horizontal plane to jointly support a first battery cell.
[0237] The hopper 221 straddles the first conveying track 21. The two ends of the first battery cell protrude from the first conveying track 21 along the width direction of the first conveying track 21. The distance between each first support member 2211 and the corresponding second support member 2212 is greater than the width of the first conveying track 21 and less than the length of the first battery cell.
[0238] The first drive unit 222 is configured to drive the material bin 221 to rise step by step, so that the first qualified battery cell in each abnormal battery cell group is carried from top to bottom by the paired first support member 2211 and second support member 2212 of each group.
[0239] The structure of the second storage component 23 may be the same as or different from that of the first storage component 22;
[0240] When the structure of the second storage component 23 is the same as that of the first storage component 22, the second storage component 23 is configured to sequentially carry the qualified second battery cells in each abnormal battery cell group from top to bottom.
[0241] Optionally, the first driving component 222 can be selected by those skilled in the art according to production needs. For example, an electric cylinder can be selected as the first driving component 222, and the first driving component 222 is configured to drive the lifting and lowering of the hopper 221.
[0242] The working process of the first storage component 22 in the first inspection process:
[0243] For ease of description, the inner wall of the first compartment plate is provided with i first support members 2211 arranged parallel from top to bottom and spaced apart, and the inner wall of the second compartment plate is provided with i second support members 2212 corresponding to each of the first support members 2211, where i is a positive integer greater than or equal to 1.
[0244] The nth first support member 2211 and the corresponding nth second support member 2212 (set opposite to each other in the same horizontal plane) are taken as the nth group of support members, 1≤n≤i, and n is a positive integer;
[0245] The first storage component 22 receives the first battery cells sequentially from top to bottom. The first drive component 222 first lowers the first storage component 22 to its lowest position, so that the upper surface of the topmost first set of support members is lower than the conveying surface of the first conveying track 21. After the first battery cell moves above the first set of support members, the first drive component 222 raises the first storage component 22 to a predetermined height, and the first set of support members lifts the first battery cell on the first conveying track 21 upward.
[0246] Subsequently, the first drive unit 222 raises the first storage component 22 to a specified height h, so that the second set of support members arrives at the position of the first set of support members, and continues to wait for the arrival of the second first battery cell;
[0247] Repeat the rising action of the first storage component 22 (the first storage component 22 rises a specified height h each time) until the i-th first battery cell is inserted into the i-th support member, which means that the first storage component 22 is full of first battery cells.
[0248] By setting several sets of corresponding first support members 2211 and second support members 2212 along the height direction in the hopper 221, the hopper 221 straddles the first conveying track 21 and is driven upward by the first drive member 222, so that the hopper 221 can carry several battery cells from top to bottom, realizing automatic storage of battery cells and improving operational efficiency; and, due to the design of the first support members 2211 and second support members 2212, there are gaps between adjacent battery cells in the hopper 221, so there is no need to lay isolation paper between the battery cells, thus avoiding damage to the blue film surface.
[0249] When the structure of the second storage component 23 is the same as that of the first storage component 22, the working process of the second storage component 23 in the first inspection process can be referred to the above description of the working process of the first storage component 22.
[0250] 2. Second inspection process:
[0251] like Figure 1-2 As shown, this process involves a conveying mechanism 1, a feeding mechanism 2, a carrying mechanism 3, a second detection mechanism, a waste collection mechanism 5, a first handling mechanism 6, and a second handling mechanism 7, wherein:
[0252] The first conveying mechanism 6 is configured to pick up at least one set of battery cell groups on the conveying mechanism 1 at a second position and place each picked-up battery cell group on the carrying mechanism 3.
[0253] The second testing mechanism is mounted above the support mechanism 3. The second testing mechanism is configured to determine whether the first and second cells in each battery cell group on the support mechanism 3 meet the standards.
[0254] The second conveying mechanism 7 is configured to pick up the substandard first and second battery cells on the carrying mechanism 3 and send them to the waste collection mechanism 5, which is located between the feeding mechanism 2 and the carrying mechanism 3.
[0255] After the substandard first battery cell on the carrying mechanism 3 is removed to the waste collection mechanism 5 by the second transport mechanism 7, the second transport mechanism 7 is also configured to pick up the first battery cell from the feeding mechanism 2 and release the picked-up first battery cell to the empty position created on the carrying mechanism 3 after the substandard first battery cell is removed.
[0256] After the substandard second battery cell on the carrying mechanism 3 is removed to the waste collection mechanism 5 by the second transport mechanism 7, the second transport mechanism 7 is also configured to pick up the second battery cell from the feeding mechanism 2 and release the picked-up second battery cell to the empty position created on the carrying mechanism 3 after the substandard second battery cell is removed.
[0257] The above provides an exemplary workflow for the second inspection process. The specific structure and working principle of each mechanism have been described in the preceding text and will not be repeated here.
[0258] It is evident that the replacement pieces for the vacant positions on the carrier mechanism 3 in the second inspection process, created by removing the substandard first / second solar cells, originate from the compliant first / second solar cells rejected in the first inspection process. In the first inspection process, the solar cell group is conveyed by the conveying mechanism 1, and the first inspection mechanism 4 determines whether the solar cells meet the standards. The rejecting mechanism 9 sends the substandard solar cells into the storage mechanism 8, and the compliant solar cells in the solar cell group are sent into the feeding mechanism 2. This operation reduces the tedious manual periodic feeding process, achieves resource recycling, and reduces production costs.
[0259] The foregoing has provided a sufficiently detailed and specific description of this application. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within the protection scope of this application. The scope of protection claimed in this application is defined by the claims, and not by the above descriptions in the embodiments.
