Description

Technical Field

[0001] The present application relates to the field of battery manufacturing technology, and in particular to an automatic centrifugal device for secondary batteries. Background Art

[0002] During the production of secondary batteries, electrolytes need to be injected into them. Electrolytes are the carriers of ion transport within the battery. However, due to the tight assembly of secondary batteries, electrolyte absorption is very slow, and electrolytes are prone to overflow, leading to inaccurate electrolyte injection, which affects the performance of the secondary batteries.

[0003] The typical secondary battery filling process uses a multiple-injection method, requiring multiple, even dozens of, injections per battery. This process results in long filling times, large errors in filling volume, and low efficiency, significantly impacting battery consistency and performance, severely restricting improvements in battery quality.

[0004] The centrifugal injection method solves the above problems to a certain extent. By evenly distributing individual batteries around the rotating shaft, the centrifugal force generated by the movement of the rotating shaft is used to accelerate the penetration of the electrolyte. However, this method requires manual placement of the batteries in the corresponding positions, and then removing and replacing new batteries after the centrifugation is completed. The degree of continuity is low, and it cannot meet the requirements of industrialized mass production of batteries, resulting in low production efficiency. Summary of the Invention

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0049] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0050] Please refer to Figure 1 、 Figure 2 and Figure 3 The present embodiment provides a secondary battery automatic centrifugation device 100, comprising a workbench 110, and a feeding assembly 120, a centrifugal assembly 130, a lifting assembly 140, a discharging assembly 150, a rack separation assembly 160, a first conveying assembly 170, and a second conveying assembly 180 arranged on the workbench 110; the feeding assembly 120 is used to convey the stacked injection rack 103 and the battery rack 105 to the centrifugal assembly 130, the injection rack 103 is used to load a syringe with electrolyte, and the battery rack 105 is used to load batteries to be injected; the lifting assembly 140 is used to load the injection rack 103 and the battery rack 105 into the centrifugal assembly 130, and to lift the centrifugal assembly 130 out after the centrifugation is completed, so as to facilitate docking with the discharge assembly 150; the rack separation assembly 160 is correspondingly arranged to the discharge assembly 150, and is used to transfer the injection rack 103 to the first conveying assembly 170, and the discharge assembly 150 is docked with the second conveying assembly 180, and is used to convey the battery rack 105 to the second conveying assembly 180.

[0051] Specifically, by stacking the injection rack 103 and the battery rack 105, syringes can be placed within the injection rack 103 and battery cells can be placed within the battery rack 105. The injection rack 103 is positioned above the battery rack 105, allowing the electrolyte in the syringes within the injection rack 103 to flow into the batteries. Before the injection rack 103 and battery rack 105 begin transporting, the syringes and batteries must be loaded accordingly and then placed on the feed assembly 120 for transport to the centrifuge assembly 130.

[0052] In order to ensure that the liquid injection rack 103 and the battery rack 105 can enter the centrifuge assembly 130 in their current posture for centrifugation, the lifting assembly 140 is required to lift and move the liquid injection rack 103 and the battery rack 105 together to carry out the loading work before centrifugation, and to lift the centrifuge assembly 130 again after centrifugation to transfer it to the next process.

[0053] After centrifugation, to facilitate the recycling of the liquid injection rack 103 and battery rack 105, the liquid injection rack 103 and battery rack 105 need to be separated and transported separately to load the syringes and batteries respectively. At this time, the rack separation assembly 160 is required to transfer the liquid injection rack 103 on the discharge assembly 150 to the first conveyor assembly 170 and transport it to a predetermined position for manual or robotic retrieval. The remaining battery racks 105 on the discharge assembly 150 are then transported to the second conveyor assembly 180 and transported to a predetermined position for manual or robotic retrieval.

[0054] The automatic secondary battery centrifugation device 100 provided in the embodiment of the present application facilitates the forward conveyance of the stacked liquid injection racks 103 and battery racks 105 through the workbench 110 and the feeding assembly 120 disposed on the workbench 110. After the liquid injection racks 103 and battery racks 105 are conveyed to the centrifuge assembly 130, the lifting assembly 140, which cooperates with the centrifuge assembly 130, smoothly transfers the liquid injection racks 103 and battery racks 105 to corresponding positions of the centrifuge assembly 130, so that the centrifuge assembly 130 can perform the centrifugal operation. After the centrifugation operation is completed, the lifting assembly 140 lifts the liquid injection racks 103 and battery racks 105 up again so that the discharge assembly 150 can continue to convey the liquid injection racks 103 and battery racks 105. After conveying them to the area where the rack separation assembly 160 is located, the rack separation assembly 160 transfers the liquid injection racks 103 to the first conveying assembly 170 to convey the liquid injection racks 103 separately for easy recycling and reuse. The remaining battery racks 105 on the discharge assembly 150 are then transferred to the second conveyor assembly 180, so that the battery racks 105 can be transported separately for easy recycling. This eliminates the need for manual loading and unloading operations at the centrifuge assembly 130, improving the automation of the battery centrifuge and thereby increasing production efficiency.

[0055] like Figure 1 、 Figure 2 and Figure 4 As shown, in an optional embodiment of the present application, two centrifugal assemblies 130 are correspondingly provided, and the workbench 110 is further provided with a sub-treating assembly 190 corresponding to the feeding assembly 120 and the centrifugal assembly 130 respectively, and a first transfer assembly 128 corresponding to the feeding assembly 120, the sub-treating assembly 190 and the centrifugal assembly 130 respectively. The sub-treating assembly 190 is used to transfer the injection rack 103 and the battery rack 105 on the feeding assembly 120 to the first transfer assembly 128, and transfer them to the centrifugal assembly 130 via the first transfer assembly 128. Each centrifugal assembly 130 is correspondingly provided with a lifting assembly 140 and a discharging assembly 150.

[0056] Specifically, in order to ensure normal feeding when two centrifugal assemblies 130 are used to perform centrifugal operations simultaneously, it is necessary to divert the materials (liquid injection rack 103 and battery rack 105) on the feed assembly 120 through the diverter assembly 190 so that part of the materials are transported to one of the centrifugal assemblies 130 and the remaining part of the materials are transported to the other centrifugal assembly 130. During the diversion and delivery, the first transfer assembly 128 corresponding to the feed assembly 120, the diverter assembly 190 and the centrifugal assembly 130 is used (it is necessary to set two corresponding to the centrifugal assemblies 130 at different positions) to facilitate the delivery of the materials to the corresponding centrifugal assemblies 130. At this time, the materials can be respectively transferred to the two first transfer assemblies 128 through the diverter assembly 190, and then transported to the centrifugal assembly 130 through the first transfer assembly 128. In addition, by providing a lifting assembly 140 and a discharging assembly 150 corresponding to each centrifugal assembly 130, the material can be smoothly transferred to the centrifugal assembly 130 for centrifugal operation, and transferred to the discharging assembly 150 after centrifugation is completed, so that the material can be further transferred to the next process through the discharging assembly 150.

[0057] like Figure 5 As shown, the feeding assembly 120 includes a first bracket 122 arranged on the workbench 110, and a first conveyor belt assembly 124 arranged on the first bracket 122, and first baffles 1242 are arranged on opposite sides of the first conveyor belt assembly 124, and a first propulsion cylinder 1244 is arranged on the first baffle 1242, and a push plate is connected to the first propulsion cylinder 1244, and the push plate is used to laterally squeeze the battery rack 105, and a first notch 1246 corresponding to the first transfer assembly 128 is provided on the first baffle 1242 to transfer the liquid injection rack 103 and the battery rack 105 to the first transfer assembly 128.

[0058] Specifically, by providing first baffles 1242 on opposite sides of the first conveyor assembly 124, the materials can be shielded, ensuring smooth material transport. Furthermore, by providing a first propulsion cylinder 1244 on the first baffle 1242, when the first propulsion cylinder 1244 pushes and squeezes the battery rack 105 laterally via the push plate, the battery rack 105 can be squeezed between the first baffle 1242 and the push plate, preventing the battery rack 105 from moving forward while the first conveyor assembly 124 continues to operate. This prevents subsequent materials from affecting the operation of the dispensing assembly 190 when the dispensing assembly 190 is diverting the current material, thereby ensuring that the entire diversion process is carried out stably and efficiently. Furthermore, by providing a first notch 1246 on the first baffle 1242 corresponding to the first transfer assembly 128, the liquid injection rack 103 and the battery rack 105 can be transferred through the first notch 1246 and moved to the first transfer assembly 128.

[0059] like Figure 6 As shown, the support assembly 190 includes a second bracket 192 arranged on the workbench 110, and a first linear module 194 and a second linear module 196 arranged on the second bracket 192; the first linear module 194 is connected to a first lifting cylinder 197, and the first lifting cylinder 197 is connected to a first shift rod 1972; the second linear module 196 is connected to a second lifting cylinder 198, and the second lifting cylinder 198 is connected to a second shift rod 1982.

[0060] Specifically, by providing the first linear module 194 and the second linear module 196 on the second bracket 192, it is advantageous to ensure rapid diversion of materials. This embodiment uses the cooperation of the first linear module 194 and the first lifting cylinder 197 as an example for explanation. When the material needs to be moved, the first linear module 194 drives the first lifting cylinder 197 to move to the corresponding position. The first lifting cylinder 197 then drives the first lever 1972 to descend to a preset height to correspond to the material to be diverted. The first linear module 194 then drives the first lifting cylinder 197 back a preset distance to divert the material to the first transfer assembly 128. The first lifting cylinder 197 drives the first lever 1972 to rise, completing a single diversion process. The diversion operation can then be repeated. It is understandable that only the first linear module 194 and the second linear module 196 can be provided as needed to achieve the above-mentioned effect, but the diversion efficiency will be reduced.

[0061] like Figure 7As shown, the first transfer component 128 includes a first slide 1282 corresponding to the feeding component 120 and the centrifugal component 130 respectively, and a first pushing cylinder 1284 arranged on the first slide 1282. The first slide 1282 is provided with a first slot hole 1282a corresponding to the first pushing cylinder 1284, so that the liquid injection rack 103 and the battery rack 105 fall to the centrifugal component 130.

[0062] Specifically, the embodiment of the present application does not impose any specific restrictions on the structural form of the first slide 1282. The first slide 1282 can be set to an L-shape, or it can be set to a straight shape or other shape according to actual needs, as long as it can ensure stable transmission. In addition, by providing a first push cylinder 1284 on the first slide 1282 and a first slot 1282a corresponding to the first push cylinder 1284, it is convenient to push the injection rack 103 and the battery rack 105 to the first slot 1282a, so that the injection rack 103 and the battery rack 105 fall through the first slot 1282a to the centrifugal assembly 130.

[0063] like Figure 8 and Figure 9 As shown, the centrifugal assembly 130 includes a driving motor 131 arranged on the workbench 110, and a rotating shaft 132 rotatably connected to the workbench 110, a support frame 133 is provided on the rotating shaft 132, and a plurality of hanging baskets 134 are rotatably provided on the support frame 133, and the hanging baskets 134 are used to load the liquid injection rack 103 and the battery rack 105; a positioning assembly 135 is provided on the hanging basket 134, and a limiting assembly 136 corresponding to the positioning assembly 135 is provided on the workbench 110, so that the opening of the hanging basket 134 can be fixed in the vertical direction.

[0064] Specifically, by connecting the drive motor 131 to the rotating shaft 132, the required drive is provided for the rotation of the rotating shaft 132. When the rotating shaft 132 rotates, the hanging basket 134 is driven to rotate synchronously, so that the batteries in the hanging basket 134 undergo centrifugal motion, thereby allowing the electrolyte in the syringe to quickly penetrate into the batteries. In addition, by providing a positioning assembly 135 on the hanging basket 134 and a limiting assembly 136 corresponding to the positioning assembly 135 on the workbench 110, the opening of the hanging basket 134 can be fixed in the vertical direction, so that the injection rack 103 and the battery rack 105 can be smoothly loaded into the hanging basket 134, and the hanging basket 134 can be lifted out after the centrifugation is completed.

[0065] like Figure 9 and Figure 10As shown, the limiting assembly 136 comprises an adjusting block 1352 arranged on the basket 134, and a cam bearing 1354 arranged on the adjusting block 1352; the limiting assembly 136 comprises a jacking cylinder 1362 arranged on the workbench 110, and a limiting disc 1364 connected with the jacking cylinder 1362, the limiting disc 1364 is sleeved on the outer ring of the rotating shaft 132, and the limiting disc 1364 is provided with a limiting groove 1366 capable of abutting against the cam bearing 1354.

[0066] Specifically, by arranging the adjusting block 1352 on the basket 134, the inclination angle of the cam bearing 1354 on the adjusting block 1352 can be conveniently adjusted, and the extension length of the cam bearing 1354 can also be adjusted. The limiting assembly 136 connects the jacking cylinder 1362 with the limiting disc 1364, when centrifugal motion is needed, the jacking cylinder 1362 drives the limiting disc 1364 to move away from the cam bearing 1354. When it is needed to place materials in the basket 134 or take materials out of the basket 134, the jacking cylinder 1362 drives the limiting disc 1364 to move to a position close to the cam bearing 1354 and abut against the cam bearing 1354, so as to limit the basket 134. The limiting disc 1364 can be provided in a circular truncated cone shape, and a convex edge is arranged at the bottom of the circular truncated cone, so that the limiting disc 1364 forms the above-mentioned limiting groove 1366, facilitating limiting.

[0067] As shown in Figure 8 and Figure 11 The centrifugal assembly 130 further comprises a cover 139 arranged on the workbench 110, the basket 134 is located in the cover 139, the cover 139 is provided with a cover plate 1392, the cover plate 1392 is provided with a first through hole 1394 and a second through hole 1396, the first through hole 1394 is used for enabling the liquid injection rack 103 and the battery rack 105 to enter the cover 139, and the second through hole 1396 is used for enabling the liquid injection rack 103 and the battery rack 105 to exit the cover 139; the rotating shaft 132 is further provided with an inductive sheet 137, and the workbench 110 is provided with an inductive switch 138 corresponding to the inductive sheet 137, so that the basket 134 corresponds to the first through hole 1394 or the second through hole 1396.

[0068] Specifically, by setting the basket 134 in the cover 139, the centrifugal process is protected from external interference, ensuring reliable centrifugation. In addition, by setting the cover plate 1392 on the cover 139, the components in the cover 139 are better protected. When the cover plate 1392 is set, in order to ensure that the material can normally enter or exit the cover 139, a first through hole 1394 and a second through hole 1396 can be formed on the cover plate 1392. When the material enters or exits, the basket 134 needs to correspond to the first through hole 1394 or the second through hole 1396. In order to ensure the accuracy of the position of the basket 134, an inductive sheet 137 can be provided on the rotating shaft 132, and a corresponding inductive switch 138 is provided on the workbench 110, so as to detect the rotation angle of the rotating shaft 132, so as to ensure that the basket 134 stays in the right position. Understandably, in order to ensure the normal movement of the material, the lifting assembly 140 only needs to correspond to the first through hole 1394 or the second through hole 1396. In order to make the material fall smoothly from the first transfer assembly 128, the first slot hole 1282a needs to correspond to the second through hole 1396.

[0069] As shown in Figure 3 , the lifting assembly 140 includes a linear motion assembly 142 provided on the workbench 110, and a push rod 144 connected with the linear motion assembly 142. The push rod 144 is slidingly connected with the workbench 110, and the end of the push rod 144 is provided with a supporting plate 146 for passing through the basket 134 to receive the liquid injection frame 103 and the battery frame 105. The lifting assembly 140 is provided in two and corresponds to the first through hole 1394 and the second through hole 1396 respectively.

[0070] Specifically, the linear motion assembly 142 can adopt a linear motion module, a cylinder or a linear push rod 144, as long as it can ensure the required lifting operation. The push rod 144 connected with the linear motion assembly 142 can slide along the workbench 110 under the driving of the linear motion assembly 142. In order to ensure the stability and smoothness of the interaction, a linear bearing can be provided between the push rod 144 and the workbench 110. In addition, by setting the supporting plate 146 at the end of the push rod 144, the supporting plate 146 can receive the liquid injection frame 103 and the battery frame 105. Understandably, in the process of transferring the liquid injection frame 103 and the battery frame 105 to the basket 134, the supporting plate 146 needs to pass through the basket 134. Therefore, a slot hole is provided at the bottom of the basket 134, which can pass through the supporting plate 146, and the slot hole is smaller than the bottom area of the battery frame 105, preventing the battery frame 105 from falling from the slot hole.

[0071] As shown in Figure 12 and Figure 13As shown, the discharging assembly 150 includes a second transfer assembly 152 corresponding to the centrifugal assembly 130, and the second transfer assembly 152 corresponds to the first conveying assembly 170, or the discharging assembly 150 includes the second transfer assembly 152 corresponding to the centrifugal assembly 130, and a second conveying belt assembly 154 corresponding to the second transfer assembly 152, so that the second transfer assembly 152 is connected with the first conveying assembly 170 through the second conveying belt assembly 154.

[0072] Specifically, in actual application, the second transfer assembly 152 corresponding to the centrifugal assembly 130 can be arranged according to actual needs, so that the second transfer assembly 152 is directly connected with the first conveying assembly 170. If the second transfer assembly 152 alone cannot deliver the material to the desired location, the second conveying belt assembly 154 needs to be added, and the delivery of the required material is realized by means of the second conveying belt assembly 154, so as to be connected with the first conveying assembly 170 through the second conveying belt assembly 154.

[0073] As shown in Figure 7 and Figure 12 , the second transfer assembly 152 includes a second chute 1522 corresponding to the centrifugal assembly 130, and a second slot hole 1524 arranged on the second chute 1522, the second slot hole 1524 corresponding to the second via hole 1396, the second chute 1522 being provided with a second pushing cylinder 1523 corresponding to the second slot hole 1524, and the second chute 1522 being further provided with a first pushing cylinder 1527 cooperating with the second pushing cylinder 1523; the first chute 1282 of the first transfer assembly 128 is provided with a first cylinder 1286 and a first shielding plate 1288 connected with the first cylinder 1286, the first shielding plate 1288 being used for shielding the first via hole 1394, the second chute 1522 being provided with a second cylinder 1525 and a second shielding plate 1526 connected with the second cylinder 1525, the second shielding plate 1526 being used for shielding the second via hole 1396.

[0074] Specifically, the structure of the first chute 1282 is not limited in the embodiment of the present application, and the first chute 1282 can be arranged as L-shaped, or linear or other forms according to actual needs, as long as it can ensure stable transmission. Among them, by arranging the second pushing cylinder 1523 corresponding to the second slot hole 1524 on the second chute 1522, when the lifting assembly 140 lifts the material onto the second chute 1522, the second pushing cylinder 1523 can timely push the material to the area deviating from the second slot hole 1524. In addition, by arranging the first pushing cylinder 1527 on the second chute 1522, the material can be pushed forward or the moving direction of the material can be changed, and in actual application, other pushing assemblies can also be arranged according to needs to adapt to different application scenarios.

[0075] By providing a first cylinder 1286 on the first slide 1282 and a first baffle 1288 connected to the first cylinder 1286, when the centrifugal assembly 130 is performing a centrifugal operation, the first baffle 1288 can block the first through-hole 1394, thereby preventing airflow from being generated at the first through-hole 1394 due to centrifugal action, thereby facilitating the stability of the centrifugal process. Similarly, by providing a second cylinder 1525 on the second slide 1522 and a second baffle 1526 connected to the second cylinder 1525, when the centrifugal assembly 130 is performing a centrifugal operation, the second baffle 1526 can block the second through-hole 1396, thereby preventing airflow from being generated at the second through-hole 1396 due to centrifugal action, thereby facilitating the stability of the centrifugal process.

[0076] like Figure 13 As shown, second baffles 1542 are provided on opposite sides of the second conveyor belt assembly 154, and a second propulsion cylinder 1544 and a blocking head connected to the second propulsion cylinder 1544 are provided on the second baffle 1542. The blocking head is used to laterally squeeze the battery rack 105. A second notch 1546 corresponding to the second conveying assembly 180 and a third pushing cylinder 1548 corresponding to the second notch 1546 are provided on the second baffle 1542 to transfer the battery rack 105 to the second conveying assembly 180.

[0077] Specifically, by providing second baffles 1542 on opposite sides of the second conveyor assembly 154, the materials can be shielded, ensuring smooth material transportation. At the same time, by providing a second propulsion cylinder 1544 on the second baffle 1542, when the second propulsion cylinder 1544 pushes and squeezes the battery rack 105 laterally through the blocking head, the battery rack 105 can be squeezed between the second baffle 1542 and the blocking head, preventing the second conveyor assembly 154 from driving the battery rack 105 forward when the second conveyor assembly 154 continues to work. In this way, when the third push cylinder 1548 pushes the current material, subsequent materials will not affect the operation of the third push cylinder 1548, which is conducive to ensuring that the entire conveying process is carried out stably and efficiently. Among them, by providing a second notch 1546 corresponding to the second conveying assembly 180 on the second baffle 1542, the battery rack 105 can be moved through the second notch 1546 to the second conveying assembly 180.

[0078] like Figure 14As shown, the rack separation assembly 160 comprises a stand 161 arranged on the workbench 110, and a mounting plate 162 in sliding connection with the stand 161, and a horizontal moving cylinder 163 arranged on the stand 161 and connected with the mounting plate 162, and a first sliding table cylinder 164 arranged on the mounting plate 162, and a second sliding table cylinder 165 arranged on the first sliding table cylinder 164, the advancing directions of the first sliding table cylinder 164 and the second sliding table cylinder 165 are consistent, and perpendicular to the advancing direction of the horizontal moving cylinder 163; a rotating cylinder 166 is arranged on the second sliding table cylinder 165, and a clamping jaw cylinder 167 is arranged on the rotating cylinder 166, and the clamping jaw cylinder 167 is used for clamping the liquid injection rack 103.

[0079] Specifically, by slidingly arranging the mounting plate 162 on the stand 161, and arranging the first sliding table cylinder 164 on the mounting plate 162, and arranging the second sliding table cylinder 165 on the first sliding table cylinder 164, the advancing directions of the first sliding table cylinder 164 and the second sliding table cylinder 165 are consistent, and perpendicular to the advancing direction of the horizontal moving cylinder 163, the movement in two directions perpendicular to each other can be realized. And the second sliding table cylinder 165 is arranged on the first sliding table cylinder 164, which is conducive to improving the movable distance and facilitating the grabbing and placing of materials. In addition, by arranging the rotating cylinder 166 on the second sliding table cylinder 165, and arranging the clamping jaw cylinder 167 on the rotating cylinder 166, after the liquid injection rack 103 is clamped by the clamping jaw cylinder 167, the rotating cylinder 166 can be rotated by a certain angle to better adapt to the first conveying assembly 170.

[0080] As shown in Figure 15 and Figure 16 The rack separation assembly 160 further comprises a connecting plate 168 arranged on the rotating cylinder 166, and a third lifting cylinder 1682 arranged on the connecting plate 168, and a liquid detection assembly 169 connected to the third lifting cylinder 1682; the liquid detection assembly 169 comprises a base plate 1692 connected to the third lifting cylinder 1682, and a first polar plate 1694 and a second polar plate 1696 arranged on the base plate 1692, the first polar plate 1694 and the second polar plate 1696 are arranged in a interdigital shape, and the first polar plate 1694 and the second polar plate 1696 are respectively connected to the positive and negative poles of the power supply, a plurality of first mounting portions 1694a are arranged on the first polar plate 1694, a plurality of second mounting portions 1696a are arranged on the second polar plate 1696, the first mounting portions 1694a and the second mounting portions 1696a are arranged one by one, and a detection needle 1698 is arranged on each of the first mounting portions 1694a and the second mounting portions 1696a, and each group of detection needles 1698 is used for extending into the same needle cylinder.

[0081] Specifically, after the claw cylinder 167 is clamped to the injection rack 103, in order to know whether the electrolyte in the syringe in the injection rack 103 has completely flowed out, it is necessary to judge whether the function of the syringe is normal, such as whether there is a blockage that prevents the electrolyte from flowing out. Since the electrolyte is usually colorless and transparent, other sensors cannot make a good judgment. The embodiment of the present application uses a detection needle 1698 for measurement. After the detection needle 1698 is inserted into the syringe, the current state of the syringe is judged based on whether the two detection needles 1698 inserted into the syringe form a short circuit. Among them, the third lifting cylinder 1682 is used to drive the detection needle 1698 as a whole to move closer to or away from the syringe, which is convenient for detection and avoidance after the detection is completed.

[0082] When using the detection needles 1698 for testing, since each injection rack 103 is provided with multiple syringes, each syringe corresponds to two detection needles 1698. To reduce the number of wiring connections, one set of detection needles 1698 can be connected to the first electrode plate 1694, and the other set of detection needles 1698 can be connected to the second electrode plate 1696. Furthermore, the first electrode plate 1694 and the second electrode plate 1696 are arranged in an interdigitated shape, with the first mounting portion 1694a and the second mounting portion 1696a respectively positioned at the interdigitated positions. This allows the detection needles 1698 at corresponding positions on the first electrode plate 1694 and the second electrode plate 1696 to be close together, thereby ensuring that the two detection needles 1698 can be properly inserted into the syringe for testing.

[0083] like Figure 7 and Figure 8 As shown, the first conveying assembly 170 includes a first conveyor belt assembly 172 arranged on the workbench 110, and at least one first blocking cylinder 174 is provided on the first conveyor belt assembly 172. The first conveyor belt assembly 172 is also provided with a limiting support rod 176 arranged along the length direction of the first conveyor belt. The limiting support rod 176 is located above the first conveyor belt assembly 172 and is used to limit the height of the injection rack 103; the second conveying assembly 180 includes a second conveyor belt assembly 182 arranged on the workbench 110, and the second conveyor belt assembly 182 is provided with a second blocking cylinder 184.

[0084] Specifically, by providing at least one first blocking cylinder 174 on the first conveyor belt assembly 172, it is convenient to limit the position of the liquid injection rack 103 when the first conveyor belt assembly 172 is in continuous operation. In addition, the first conveyor belt assembly 172 is also provided with a limiting support rod 176 arranged along the length direction of the first conveyor belt, which is conducive to ensuring the stable transportation of the liquid injection rack 103 and preventing the liquid injection rack 103 from accidentally falling when the transportation distance of the first conveyor belt assembly 172 is too long.

[0085] Similarly, by setting a second blocking cylinder 184 on the second conveyor belt assembly 182, the battery rack 105 can be limited when the second conveyor belt assembly 182 is in continuous operation to prevent disorderly continuous forward movement, which is conducive to improving the convenience of operation.

[0086] like Figure 18 and Figure 19 As shown, the secondary battery automatic centrifugation device 100 also includes a third conveying assembly 188 arranged on the workbench 110, and the third conveying assembly 188 includes a third conveyor belt assembly 1882 arranged on the workbench 110, and the third conveyor belt assembly 1882 is provided with a third blocking cylinder 1884; the third conveyor belt assembly 1882 is docked with the second conveyor belt assembly 182, and the conveying end of the second conveyor belt assembly 182 is provided with a second pushing cylinder 186 to push the battery rack 105 to the third conveyor belt assembly 1882.

[0087] Specifically, a second push cylinder 186 is provided at the conveying end of the second conveyor belt assembly 182 to facilitate pushing the battery rack 105 to the third conveyor belt assembly 1882, thereby better adapting to the actual production environment. In addition, a third blocking cylinder 1884 is provided on the third conveyor belt assembly 1882 to limit the battery rack 105 while the third conveyor belt assembly 1882 is in continuous operation, preventing disorderly and continuous forward movement, which helps to improve the convenience of operation.

[0088] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
