Description

Technical Field

[0001] The present invention relates to the technical field of battery cell production, and in particular to a battery cell passivation treatment system. Background Art

[0002] Cell passivation technology aims to improve the performance and stability of the battery by forming a passivation layer on the surface or edge of the cell to reduce surface defects and micro damage. The passivation layer can effectively reduce the recombination of charge carriers, increase the minority carrier lifetime and open circuit voltage of the cell, and thus significantly improve the conversion efficiency of the solar cell. Existing cell passivation equipment usually transfers the carrier containing the cell into the furnace body by means of a tray horizontally or by lifting. The tray carries several carriers. In the above scheme, the carrier is loaded into the furnace via a tray. The carrier is moved multiple times, which not only affects the positioning accuracy of the cell in the carrier, but also increases the complexity of the process steps and mechanical structure of loading and unloading the cell into the furnace body. Summary of the Invention

[0007] Furthermore, at least two supporting members are provided on the circumference of the bottom of the furnace cover, and the supporting members are used to receive the passivation unit, and the surface to be passivated of the passivation unit is arranged downward.

[0008] Furthermore, the furnace cover includes a top cover and a rotating carrier provided at the lower part of the top cover, one end of the rotating carrier is connected to a driving mechanism, and at least two supporting members are provided on the circumference of the bottom of the rotating carrier. The driving mechanism drives the rotating carrier to rotate to transfer the passivation units that have been passivated to the material change position in sequence, or, transfer the passivation units to be passivated on the material change position to the cache position of the furnace cover in sequence.

[0009] Furthermore, the supporting member includes a fixing seat fixedly connected to the rotating carrier, and a limiting member provided on the fixing seat, the limiting member is provided with a slide groove, and the slide groove is used to carry the carrier to fix the passivation unit on the limiting member.

[0010] Furthermore, the chute includes a closed end and an open end, the open end is arranged outward, and the transport mechanism delivers the passivation unit into the limiting member from the open end.

[0011] Furthermore, one end of the limit member is connected to a driving component, and the driving component can drive the limit member to rotate a preset angle, and at the same time drive the passivation unit to rotate the preset angle, and the preset angle is less than or equal to 180 degrees. The preset angle makes the open end of the slide groove higher than the closed end of the slide groove, or makes the open end and the closed end face inward in opposite directions.

[0012] Furthermore, the transport mechanism grabs the passivation unit on the feeding mechanism and flips it 90 degrees, rotates the surface to be passivated of the passivation unit from the side to the bottom, and then loads it on the furnace cover at the material change position, so that the surface to be passivated of the passivation unit on the furnace cover faces downward.

[0013] Furthermore, the transport mechanism includes a multi-axis manipulator and a transfer fork provided at the end of the multi-axis manipulator, the transfer fork includes a positioning member and a support column, the positioning member and the support column act on two adjacent surfaces of the passivation unit to position the passivation unit in the transfer fork.

[0014] Furthermore, the feeding mechanism includes a loading mechanism and a unloading mechanism arranged side by side, and the loading mechanism and the unloading mechanism are both arranged on the same side of the carrying mechanism and have opposite conveying directions.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 、 Figure 2As shown, the present application provides a battery cell passivation treatment system, including: a feeding mechanism 1, a passivation furnace 2 and a carrying mechanism 3, wherein the feeding mechanism 1 is used to transport a plurality of passivation units 100, provide the passivation units 100 to the carrying mechanism 3, or receive the passivation units 100 transferred by the carrying mechanism 3 and transfer them out of the battery cell passivation treatment system. The passivation unit 100 includes a plurality of stacked battery cells and a carrier 101 on which the plurality of stacked battery cells are mounted. The cross-sections of the plurality of stacked battery cells together constitute a surface 102 to be passivated of the passivation unit 100. A passivation chamber for accommodating the plurality of carriers 101 is provided in the passivation furnace 2. The passivation furnace 2 is also provided with a passivation mechanism for emitting a passivation particle source. The surface 102 to be passivated in the passivation chamber is arranged downward to directly process the surface 102 to be passivated. The passivation particle source in the furnace body 22 can adhere to the surface 102 to be passivated of the passivation unit 100 in a vacuum environment to complete the passivation of the surface 102 to be passivated of the passivation unit 100.

[0031] The passivation furnace 2 includes a furnace body 22 and a liftable furnace cover 21 provided on the top of the furnace body 22. The furnace cover 21 is liftable and the passivation units 100 provided on the furnace cover 21 can enter and exit the passivation furnace 2 together. The furnace cover 21 is moved out of the passivation furnace 2 and the passivation units 100 that have been passivated are transferred to the material replacement position in sequence. The material replacement position is provided on the side facing the carrier mechanism 3, or the passivation units 100 to be passivated on the material replacement position are transferred to the cache position of the furnace cover 21. It should be noted that the cache position includes any other position except the material replacement position, but the passivation units 100 on the cache position are never separated from the furnace cover 21. A carrier 214 is provided on the furnace cover 21. The carrier 214 is used to load at least two passivation units 100. The surface 102 to be passivated of the passivation unit 100 is set downward. When the carriers 214 provided on the furnace cover 21 are all equipped with the passivation units 100, all the passivation units 100 are loaded. The transport mechanism 3 is provided between the passivation furnace 2 and the feeding mechanism 1, and is used to move the passivation unit 100 that has been passivated and is placed on the transfer furnace cover 21 at the material change position to the feeding mechanism 1, or the transport mechanism 3 is used to transfer the passivation unit 100 to be passivated on the feeding mechanism 1 to the furnace cover 21 at the material change position, and the furnace cover 21 moves the passivation units 100 on the multiple carriers 214 to the material change position in turn, and the passivation unit 100 moved to the material change position is taken out from the carrier 3 and placed on the feeding mechanism 1, and then the feeding mechanism 1 moves the passivation unit 100 that has been passivated to other equipment, or the furnace cover 21 moves the empty carriers 214 moves to the material change position in sequence, and the passivation units 100 that have not been passivated at the front end of the feeding mechanism 1 are transported in sequence by the carrying mechanism 3 to the unloaded carrier 214 on the material change position, thereby transferring the passivation units 100 to be passivated to the unloaded carrier 214 on the furnace cover 21 in sequence, or transferring the passivation units 100 that have been passivated on the furnace cover 21 to the feeding mechanism 1 in sequence, so as to complete the loading and unloading of the passivation units 100 on the furnace cover 21. After all the passivation units 100 are loaded and unloaded on the furnace cover 21, the furnace cover 21 moves the passivation units 100 into or out of the furnace body 22 of the passivation furnace 2.

[0032] It should be noted that the above-mentioned supporting member 214 may also be a structure provided on the furnace cover 21 and formed integrally with the furnace cover 21 , and does not need to be assembled separately.

[0033] It should be noted that the support member 214 can also be directly fixed on the furnace cover 21, and the furnace cover 21 is rotatably connected to an external rotating mechanism. The rotating mechanism drives the furnace cover 21 to rotate and rotates the support member 214 provided on the furnace cover 21 to the material change position.

[0034] Compared with the prior art, the present invention uses the furnace cover 21 of the passivation furnace 2 as a carrier for carrying the passivation unit 100, cooperates with the carrying mechanism 3 to complete the loading and unloading of all the passivation units 100, and directly covers the upper part of the furnace body 22 to completely enclose the passivation units 100 on the furnace cover 21 inside the furnace body 22, and participates in the passivation process of the cross-section of the battery cells inside the furnace body 22. The cross-section of the battery cells loaded in the carrier on the furnace cover 21 is passivated and coated inside the furnace body 22, without the need for other supporting structures, and the structure is simple. Among them, the furnace cover 21 moves the passivation unit 100 on the carrier 214 to the material change position in turn, or moves the empty carrier 214 to the material change position, and cooperates with the transport mechanism 3 to unload the passivation unit 100 at the material change position in turn, or loads the passivation unit 100 on the feed mechanism 1 onto the carrier 214 at the material change position, and cooperates to complete the loading and unloading actions of the passivation unit 100, thereby reducing the number of times the battery cell carrier 101 is transported, improving the efficiency of loading and unloading the passivation unit 100, and preventing the stacked battery cells in the carrier 101 from being shaken due to multiple transportation of the battery cell carrier, thereby further improving the accuracy of the placement of the battery cells in the carrier 101, ensuring that the cut surface of the stacked battery cells is neat, and thus improving the passivation quality of the cut surface of the battery cells.

[0035] In some embodiments, reference Figure 2 As shown, the furnace cover 21 includes a top cover 211 and a rotating carrier 212 arranged at the lower part of the top cover 211. One end of the rotating carrier 212 is connected to a driving mechanism 213, which is fixed on the top cover 211. The supporting member 214 is circumferentially arranged at the bottom of the rotating carrier 212. The driving mechanism 213 is used to drive the rotating carrier 212 to rotate and rotate multiple supporting members 214 to the material change position in sequence. The passivation unit 100 is limited in the supporting member 214 to rotate with the rotating carrier 212 to rotate to the material change position or the cache position.

[0036] Specifically, such as Figure 3 As shown, the carrier 214 includes a fixing seat 2141 fixedly mounted on the rotating carrier 212, and a limiting member 2142 connected to the fixing seat 2141, and a slide groove 21422 is provided on the limiting member 2142, and the slide groove 21422 is used to carry the carrier 101 loaded with battery cells. In order to facilitate the smooth insertion of the passivation unit 100, the slide groove 21422 includes a closed end and an open end, and the open end is arranged outward, that is, toward the side of the carrying mechanism 3. The open end is also provided with an external oval opening, and the carrier 101 is provided with a guide member that cooperates with the slide groove 21422. The carrying mechanism 3 puts the guide member on the captured passivation unit 100 into the slide groove 21422 until the guide member abuts against the closed end, so that the passivation unit 100 is positioned on the limiting member 2142, so as to fix the passivation unit 100 on the limiting member 2142 of the furnace cover 21, and the external oval opening has a guiding function.

[0037] In other embodiments, one end of the limit member 2142 is connected to a driving component, which can drive the limit member 2142 to rotate a preset angle, and at the same time drive the passivation unit 100 to rotate a preset angle, which is less than or equal to 180 degrees, so that the open end of the slide groove 21422 is higher than the closed end of the slide groove 21422, or the open end and the closed end are oppositely facing inward. Specifically, when the preset angle is less than 180 degrees, the open end of the chute 21422 is higher than the closed end, so that the passivation unit 100 is directly pressed against the closed end of the chute 21422 under the action of gravity, and the carrier 101 of the passivation unit 100 is further stabilized in the chute 21422, so that the passivation unit 100 will not shift in the chute 21422 under the action of external force; when the preset angle is equal to 180 degrees, the chute 21422 originally at the material change position opens outward, that is, to one side of the carrier mechanism 3, and when the limit member 2142 rotates 180 degrees, the open end and the closed end of the chute 21422 face opposite directions. On the inner side, the passivation unit 100 is simultaneously flipped 180 degrees. The purpose is to be compatible with battery cells with multiple cut surfaces. When two opposite sides of the same battery cell are both cut surfaces, after one passivation surface is passivated in the furnace body 22, the limit member 2142 is rotated 180 degrees by the driving component to make the passivation surface of the other opposite side flipped downward, so that the battery cells with two cut surfaces on the same carrier 101 can be completed in one furnace body 22 at one time, and there is no need to complete the passivation process of the same battery cell with two cut surfaces in multiple times, thereby improving the passivation efficiency of the battery cell with two opposite sides being cut surfaces.

[0038] In some embodiments, as Figure 4 As shown, the carrier 101 includes a frame, which is used to load stacked battery cells. A guide member is provided on the frame, which is a raised guide column 1011. The guide column 1011 can be set as two symmetrical ones. The two guide columns 1011 both enter the slide groove 21422 and are set parallel to the slide groove 21422, so that the carrier 101 can be horizontally limited in the slide groove 21422. It should be noted that the guide member can also be a guide wheel or roller bearing, etc., which can support and roll the structure. The limiting cooperation method is simple and convenient, and does not require a complicated locking mechanism. It can be limited on the rotating carrier 212, which makes loading and unloading materials convenient and quick, further improving the efficiency of the carrier mechanism 3 in loading and unloading the passivation unit 100.

[0039] In some embodiments, the passivation unit 100 on the feeding mechanism 1 is placed vertically, and the surface to be passivated 102 formed by the stacked cross-sections of the battery cells faces the side of the carrier 101. The transport mechanism 3 picks up the passivation unit 100 from the feeding mechanism 1 and flips the passivation unit 100 90 degrees, so that the surface to be passivated 102 of the passivation unit 100 is set downward, facing the open side of the furnace body 22, and the open side of the furnace body 22 is upward, and then moved into the furnace body 22 together with the furnace cover 21, and the surface to be passivated 102 of the passivation unit 100 in the furnace body 22 faces downward, that is, facing the passivation mechanism that emits the passivation particle source in the furnace body 22.

[0040] In some embodiments, as Figure 5 As shown, the transport mechanism 3 includes a multi-axis manipulator 31 and a transfer fork 32 provided at the end of the multi-axis manipulator 31. The transfer fork 32 includes a positioning member 322 and a support column 321. The positioning member 322 and the support column 321 act on two adjacent surfaces of the passivation unit 100 to position the passivation unit 100 in the transfer fork 32. Specifically, the support column 321 is clamped in the upper part of the carrier 101, and the positioning member 322 is limited to the side of a side surface of the upper part of the carrier 101. When the transport mechanism 3 rotates the passivation unit 100 90 degrees, the positioning member 322 limited to the side of a side surface of the carrier 101 rotates upward to flip the side surface of the passivation unit 100 downward, that is, the side surface of the passivation unit 100 is the surface 102 of the battery cell to be passivated.

[0041] In some embodiments, the feeding mechanism 1 further includes a loading mechanism and a unloading mechanism, which are arranged side by side on the same side of the carrying mechanism 3 and have opposite conveying directions. The loading mechanism conveys the unpassivated passivation unit 100 to the end close to the carrying mechanism 3, and the unloading mechanism conveys the passivation unit 100 that has been passivated to the rear end of the unloading mechanism, which is also the end away from the carrying mechanism 3. The feeding mechanism 1 is docked with an external structure to supply a carrier 101 loaded with a number of stacked battery cells to the feeding mechanism 1, or to separate the stacked battery cells that have been passivated from the carrier 101.

[0042] Preferably, the feeding mechanism 1 also includes an annealing mechanism. The carrying mechanism 3 removes the passivation unit 100 that has been passivated from the material change position of the furnace cover 21 and then sends it into the annealing mechanism. The annealing mechanism heats and cools the passivation unit 100 that has been passivated, which can significantly improve the performance of the passivation layer on the cut surface of the passivation unit 100 and the conversion efficiency of the battery.

[0043] Specifically, such as Figure 6As shown, the passivation furnace 2 of the present invention further includes a partition 221 and a vapor deposition mechanism 222 arranged in the passivation furnace 2. The partition 221 separates the passivation unit 100 on the furnace cover 21 from the vapor deposition mechanism 222. The passivation unit 100 is placed above the partition 221. The vapor deposition mechanism 222 is arranged below the partition 221. A hole is provided on the partition 221. The vapor deposition mechanism 222 is arranged opposite to the hole and emits vapor deposition particles to the passivation surface 102 of the passivation unit 100 facing the hole. The vapor deposition particles The particles are attached to the surface to be passivated 102 of the passivation unit 100 directly above the channel through the channel. Some of the evaporated particles emitted by the evaporation mechanism 222 are blocked by the bottom of the partition 221 and attached to the bottom of the partition 221. Because the evaporation mechanism 222 has only relatively concentrated and dense evaporation particles near the evaporation particle emission port, and the evaporation particles are evenly distributed, they can directly adhere to the surface to be passivated 102 through the channel, so that the thickness of the passivation layer on the passivation surface is uniform, thereby improving the quality of the battery cell coating.

[0044] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description.

At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention.
