Abstract
Description
Technical Field
[0001] This invention relates to the field of lithium battery production technology, and in particular to a cell casing device and a battery production system. Background Technology
[0002] With the development of energy technology, lithium battery technology has emerged. To achieve the voltage and capacity required for the operating environment, multiple cells need to be stacked and connected in series or parallel to form a pouch lithium battery module. Pouch lithium batteries are wrapped in an aluminum-plastic film, which has low hardness and releases a lot of heat during discharge. Typically, the cells are placed in an aluminum shell for reinforcement and then stacked into a pouch battery module to facilitate heat dissipation.
[0003] In traditional technology, to save space and reduce the overall size of the battery, the aluminum casing is designed to be as compact as possible. However, the large tolerances in the shape of the battery cells make it difficult for general mechanical equipment to automatically insert them into the aluminum casing. Lithium-ion batteries are liquid batteries, protected by aluminum-plastic film encapsulation. However, this film is relatively thin, and if the positioning accuracy of automated mechanical installation is insufficient, it can easily break the film, causing leakage or posing a risk of smoke and fire. Therefore, the industry still largely relies on manual insertion of the cells. However, the current manual method of inserting cells is inefficient and hinders production capacity improvement. Summary of the Invention
[0004] Therefore, it is necessary to overcome the shortcomings of existing technologies and provide a cell insertion device and battery production system that can effectively improve the cell insertion efficiency and increase production capacity.
[0005] The technical solution is as follows: A battery cell insertion device for installation on a driving device, the battery cell insertion device comprising: a transverse mechanism for connection to the driving device; a pickup mechanism comprising a pickup frame and a pickup element, the transverse mechanism being drivenly connected to the pickup frame, the transverse mechanism being used to drive the pickup frame to move along the length direction of the transverse mechanism, the pickup frame having a rotating shaft, the pickup element being rotatably connected to the pickup frame through the rotating shaft, initially, the length direction of the pickup element being set at an angle to the length direction of the transverse mechanism, the pickup element being used to pick up and release the battery cell; and a flattening mechanism connected to the pickup frame, the flattening mechanism engaging with the pickup element, the flattening mechanism being used to drive the pickup element to rotate around the rotating shaft.
[0006] In the aforementioned battery cell loading device, during operation, firstly, a driving device such as a robotic arm or motion platform moves the device to the loading station. At this point, the pick-up piece is tilted relative to the horizontal direction. The flattening mechanism drives the pick-up piece to rotate around its axis, making it horizontal. After the tilt, the pick-up piece approaches and picks up the battery cell. After picking it up, the driving device lifts the battery cell. At this point, the flattening mechanism releases its force, and the pick-up piece returns to its initial state, causing the battery cell to tilt relative to the length direction of the transverse movement mechanism. The driving device then moves the battery cell to the top of the casing. Next, the transverse movement mechanism adjusts... The battery cell is positioned horizontally, placing it in the preset casing insertion position. Then, the robotic arm moves the battery cell insertion device downwards, causing the end of the battery cell closest to the casing to contact the inner edge of the casing. After contact, the insertion device continues downwards, and the battery cell begins to rotate due to external force. A lateral movement mechanism adjusts the battery cell's horizontal position, ensuring it remains close to the casing edge throughout the downward movement. At this point, the battery cell rotates in a fan-shaped motion around the casing edge. Finally, the bottom of the battery cell is flush with the bottom of the casing, the battery cell is fully inserted, and the pickup releases and resets the battery cell. This battery cell insertion device descends at an angle to the casing during insertion, and the lateral movement mechanism adjusts the battery cell's horizontal position, allowing the battery cell to be inserted one end first and then completely inside the casing. This improves insertion efficiency and prevents damage to the battery cell from the casing edge, enhancing the reliability of automatic battery cell insertion.
[0007] In one embodiment, there are at least two picking mechanisms and at least two flattening mechanisms, and the picking mechanisms and flattening mechanisms are arranged in a one-to-one correspondence. Both picking frames are driven and connected to the transverse movement mechanism, which is used to drive the two picking frames to move closer to or further away from each other.
[0008] In one embodiment, the pickup mechanism further includes a biasing member disposed between the pickup frame and the pickup member, and the biasing member and the rotating shaft are spaced apart on the pickup frame. The biasing member is used to drive the pickup member to maintain its initial state.
[0009] In one embodiment, the pickup frame includes a transmission seat, a buffer, and a rotating seat. The rotating seat is drivenly connected to the transverse mechanism. The rotating seat is movably connected to the transmission seat through the buffer. The rotating seat and the buffer are buffered together. The rotating shaft is disposed on the rotating seat. The pickup is rotatably connected to the rotating seat through the rotating shaft.
[0010] In one embodiment, the pickup mechanism further includes a sensor connected to the rotating seat and inductively engaging with the pickup element, the sensor being used to detect the rotation angle of the pickup element.
[0011] In one embodiment, the flattening mechanism includes a first driving member and a deflecting frame. The first driving member is connected to the pickup frame, and the deflecting frame is connected to the output end of the first driving member. The deflecting frame abuts against one side of the pickup member near the pickup frame. The first driving member drives the deflecting frame to move along the height direction of the lateral movement mechanism.
[0012] In one embodiment, the deflection frame is provided with a first abutment and a second abutment, which are spaced apart on the deflection frame and respectively located at opposite ends of the rotating shaft. Both the first abutment and the second abutment abut against the pickup, and the first abutment and the second abutment have the same length.
[0013] In one embodiment, the traversing mechanism includes a traversing frame, a second driving member, and a transmission member. The second driving member and the transmission member are both connected to the traversing frame. The second driving member is drivenly connected to the transmission member, and the transmission member is drivenly connected to the pickup frame.
[0014] In one embodiment, the transmission component includes a bidirectional threaded screw and a screw nut, the two transverse frames are respectively connected to the two screw nuts, the two screw nuts are respectively connected to two sets of opposite-direction threaded drives on the bidirectional threaded screw, and the second driving component is used to drive the bidirectional threaded screw to rotate.
[0015] A battery production system includes a drive device and a cell loading device as described in any one of the above, wherein the drive device is connected to the transverse mechanism.
[0016] In the aforementioned battery production system, during operation, firstly, driving equipment such as robotic arms and motion platforms move the cell loading device to the loading station. At this point, the picking component is tilted relative to the horizontal direction. The flattening mechanism drives the picking component to rotate around a pivot, making the picking component horizontal. After tilting, the picking component approaches and picks up the cell. After picking up, the driving equipment lifts the cell. At this time, the flattening mechanism releases its force, and the picking component returns to its initial state, causing the cell to tilt relative to the length direction of the lateral movement mechanism. The driving component then moves the cell to the top of the casing. Next, the lateral movement mechanism adjusts... The battery cell is positioned horizontally, placing it in the preset casing insertion position. Then, the robotic arm moves the battery cell insertion device downwards, causing the end of the battery cell closest to the casing to contact the inner edge of the casing. After contact, the insertion device continues downwards, and the battery cell begins to rotate due to external force. A lateral movement mechanism adjusts the battery cell's horizontal position, ensuring it remains close to the casing edge throughout the downward movement. At this point, the battery cell rotates in a fan-shaped motion around the casing edge. Finally, the bottom of the battery cell is flush with the bottom of the casing, the battery cell is fully inserted, and the pickup releases and resets the battery cell. This battery cell insertion device descends at an angle to the casing during insertion, and the lateral movement mechanism adjusts the battery cell's horizontal position, allowing the battery cell to be inserted one end first and then completely inside the casing. This improves insertion efficiency and prevents damage to the battery cell from the casing edge, enhancing the reliability of automatic battery cell insertion. Attached Figure Description

[0032] Please see Figures 1 to 5 , Figure 1 A schematic diagram of the structure of the battery cell housing device 100 according to an embodiment of the present invention is shown. Figure 1 ; Figure 2 A schematic diagram of the structure of the battery cell housing device 100 according to an embodiment of the present invention is shown. Figure 2 ; Figure 3 A schematic diagram of the structure of the battery cell housing device 100 according to an embodiment of the present invention is shown. Figure 3 ; Figure 4This diagram illustrates the initial position of the battery cell housing device 100 according to one embodiment of the present invention. Figure 5 This diagram illustrates the positional relationship of the battery cell insertion device 100 after insertion into the casing according to an embodiment of the present invention. An embodiment of the present invention provides a battery cell insertion device 100 for installation on a driving device. The battery cell insertion device 100 includes: a traversing mechanism 110, a picking mechanism 120, and a flattening mechanism 130. The traversing mechanism 110 is connected to the driving device. The picking mechanism 120 includes a picking frame 121 and a picking element 122, and the traversing mechanism 110 is drivenly connected to the picking frame 121. The traversing mechanism 110 drives the picking frame 121 to move along its length direction. The picking frame 121 is provided with a rotating shaft 123, and the picking element 122 is rotatably connected to the picking frame 121 through the rotating shaft 123. In the initial state, the length direction of the picking element 122 is angled to the length direction of the traversing mechanism 110, and the picking element 122 is used to pick up and release the battery cell 200. The flattening mechanism 130 is connected to the pickup frame 121 and engages with the pickup component 122. The flattening mechanism 130 is used to drive the pickup component 122 to rotate around the rotating shaft 123.
[0033] In operation, the aforementioned battery cell loading device 100 is first moved to the loading station by a drive device such as a robotic arm or motion platform. At this time, the picking member 122 is tilted relative to the horizontal direction. The flattening mechanism 130 drives the picking member 122 to rotate around the rotating shaft 123, making the picking member 122 horizontal. After the rotation, the picking member 122 approaches and picks up the battery cell 200. After picking up, the drive device lifts the battery cell 200. At this time, the flattening mechanism 130 releases its force, and the picking member 122 returns to its initial state, causing the battery cell 200 to tilt relative to the length direction of the transverse movement mechanism 110. The drive device then moves the battery cell 200 above the housing 300. Next, the transverse movement mechanism 110 adjusts the battery cell. The horizontal position of the battery cell 200 places the battery cell 200 in the preset housing position. Then, the robotic arm moves the battery cell housing device 100 downward, so that the end of the battery cell 200 near the housing 300 first contacts the inner edge of the housing 300. After contact, the battery cell housing device 100 continues to move downward, and the battery cell 200 begins to rotate due to the external force. The horizontal position of the battery cell 200 is adjusted by the action of the horizontal movement mechanism 110, so that the battery cell 200 always moves closely to the edge of the housing 300 during the pressing process. At this time, the battery cell 200 performs a fan-shaped rotation with the edge of the housing 300 as the rotation axis. Finally, the bottom of the battery cell 200 is flat with the bottom of the housing 300, the battery cell 200 is installed in the housing, and the pickup 122 releases the battery cell 200 and resets. The battery cell insertion device 100 descends at an angle to the housing 300 during insertion, and the horizontal position of the battery cell 200 is adjusted by the horizontal movement mechanism 110, so that the battery cell 200 is inserted into the housing first at one end and then completely inserted into the housing. This helps to improve the insertion efficiency and avoids damage to the battery cell 200 by the edge of the housing 300, thereby improving the reliability of the automatic insertion of the battery cell 200.
[0034] Since the driving device is not the inventive point or the main improvement object of this embodiment, this embodiment does not specifically limit the driving device. It only needs to satisfy the requirement of driving the battery cell housing device 100 to move in position. For example, the driving device can be a robot, a robotic arm, a multi-axis motion platform, etc.
[0035] It should be noted that the drive connection between the transverse mechanism 110 and the pickup frame 121 should be understood as the transverse mechanism 110 being connected to the pickup frame 121. The connection method can be direct connection or indirect connection. The transverse mechanism 110 can also serve as a power source to drive the pickup frame 121 to move the pickup component 122 and the battery cell 200 along the length direction of the transverse mechanism 110.
[0036] In order to further understand and explain the length direction of the transverse mechanism 110, Figure 1 For example, the length direction of the transverse moving mechanism 110 is... Figure 1 The direction pointed to by any arrow on the straight line S1.
[0037] In one embodiment, see Figure 1 , Figure 2 and Figure 3 There are at least two pickup mechanisms 120 and at least two flattening mechanisms 130. The pickup mechanisms 120 and flattening mechanisms 130 are configured in a one-to-one correspondence. Both pickup frames 121 are driven and connected to a lateral movement mechanism 110, which drives the two pickup frames 121 to move closer to or further away from each other. Thus, on the one hand, when the two pickup mechanisms 120 act on a single battery cell 200, it helps improve the pickup stability of that battery cell 200, preventing it from falling. On the other hand, it allows for the simultaneous pickup and placement of two battery cells 200 into the casing. Furthermore, the lateral movement mechanism 110 can simultaneously drive the two battery cells 200 closer to or further away, adjusting the relative distance between the battery cells 200, thereby facilitating the simultaneous placement of two battery cells 200 into the casing.
[0038] In the initial state, the length direction of the pickup component 122 is angled to the length direction of the lateral movement mechanism 110. This can be achieved by the pickup component 122 tilting relative to the horizontal under its own weight, picking up the battery cell 200 so that the two cells 200 are in a figure-eight shape. Alternatively, it can be achieved through external force or support, causing the pickup component 122 to move the battery cell 200 at an angle to the horizontal. Figure 4 As shown.
[0039] In one embodiment, see Figure 2 The pickup mechanism 120 also includes an offset member 124, which is disposed between the pickup frame 121 and the pickup member 122. The offset member 124 and the rotating shaft 123 are spaced apart on the pickup frame 121. The offset member 124 is used to drive the pickup member 122 to maintain its initial state. Thus, when the rotating shaft 123 is installed in the middle position between the pickup frame 121 and the pickup member 122, the pickup member 122 will not remain tilted under its own weight. By setting the offset member 124 on the outside of the pickup frame 121 relative to the rotating shaft 123, the pickup member 122 is tilted relative to the horizontal position under the offset action of the offset member 124 in the initial state, so that the two pickup members 122 are in a figure-eight shape. When it is necessary to pick up the battery cell 200, the flattening mechanism 130 drives the picking member 122 to rotate, so that the picking member 122 is in a horizontal state, which makes it easier to pick up the battery cell 200 without damaging the battery cell 200, which helps to protect the battery cell 200 and improves the reliability of the picking mechanism 120.
[0040] Specifically, please refer to Figure 1 , Figure 2 and Figure 3The pickup frame 121 includes a transmission base 1211, a buffer 1212, and a rotating base 1213. The rotating base 1213 is connected to the traversing mechanism 110 via a transmission connection, and is movably connected to the transmission base 1211 via the buffer 1212, with the rotating base 1213 and the buffer 1212 providing a buffered fit. A rotating shaft 123 is mounted on the rotating base 1213, and the pickup component 122 is rotatably connected to the rotating base 1213 via the rotating shaft 123. Thus, the transmission base 1211 can drive the buffer 1212, the rotating base 1213, the pickup component 122, and the picked-up battery cell 200 to move on the traversing mechanism 110. When picking up the battery cell 200, the buffer 1212 helps reduce the pressure and impact of the pickup component 122 on the battery cell 200, thus protecting the battery cell 200.
[0041] The buffer 1212 can be a spring, airbag, foam elastic material, rubber, silicone or other buffer material.
[0042] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The buffer element 1212 is a spring. The two ends of the spring are connected to the transmission seat 1211 and the rotating seat 1213, respectively. This design results in a simple structure with high stability, which helps improve the overall structural stability and service life of the pickup structure. Simultaneously, the elastic deformation of the spring ensures the buffering effect of the buffer element 1212. This embodiment only provides one specific implementation of the buffer element 1212, but is not limited thereto.
[0043] Further, please refer to Figure 1 , Figure 2 and Figure 3 There are two or more buffer elements 1212, which are spaced apart on the transmission seat 1211. Specifically, in this embodiment, there are four buffer elements 1212, which are evenly distributed between the transmission seat 1211 and the rotating seat 1213.
[0044] Optionally, the pickup component 122 can pick up the battery cell 200 by clamping, sucking, picking up, sticking or other pickup methods.
[0045] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The pickup component 122 is a vacuum suction cup, which picks up the battery cell 200 using negative pressure. This helps protect the battery cell 200 from damage during pickup, improves the production yield of the battery cell 200, and thus enhances the operational reliability of the pickup component 122. This embodiment only provides one specific implementation of the pickup component 122, but is not limited thereto.
[0046] Further, please refer to Figure 1 , Figure 2 and Figure 3 A sponge layer 126 is provided on the side of the pickup 122 near the battery cell 200. This helps to further reduce the impact of the pickup 122 on the battery cell 200, thereby ensuring that the battery cell 200 is not damaged.
[0047] In one embodiment, see Figure 1 The pickup mechanism 120 also includes a sensor 125, which is connected to the rotating seat 1213 and engages with the pickup 122. The sensor 125 is used to detect the rotation angle of the pickup 122. Thus, through the detection function of the sensor 125, the rotation angle of the battery cell 200 can be monitored in real time during the insertion operation, and fed back to the transverse mechanism 110. This allows the transverse mechanism 110 to follow synchronously and automatically adjust the distance between the two battery cells 200 according to the change in the angle of the battery cell 200. This ensures that the battery cell 200 always moves in close contact with the edge of the housing 300 during the pressing process. At this time, the battery cell 200 rotates in a fan shape with the edge of the housing 300 as the rotation axis 123, which helps to improve the accuracy and automatic insertion efficiency of the battery cell 200 during the insertion operation.
[0048] Optionally, the sensing element 125 may be a light sensor, a distance sensor, an angle sensor, or other sensing device.
[0049] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The sensing element 125 is an angle encoder. This provides high accuracy, strong reliability, and convenient control, facilitating real-time feedback of the angle deflection information of the battery cell 200 to the lateral movement mechanism 110, thereby achieving automatic pitch control and improving the working efficiency and reliability of the battery cell housing device 100. This embodiment only provides a specific implementation of the sensing element 125, but is not limited thereto.
[0050] In one embodiment, see Figure 1 and Figure 2 The flattening mechanism 130 includes a first driving member 131 and a deflecting frame 132. The first driving member 131 is connected to the pickup frame 121, and the deflecting frame 132 is connected to the output end of the first driving member 131. The deflecting frame 132 abuts against the side of the pickup 122 near the pickup frame 121, and the first driving member 131 drives the deflecting frame 132 to move along the height direction of the lateral movement mechanism 110. In this way, through the abutting action of the deflecting frame 132, the pickup 122 can be changed from an inclined state to a horizontal state. The action is simple, reliable, and conducive to improving the working efficiency of the flattening mechanism 130.
[0051] In order to further understand and explain the height direction of the transverse movement mechanism 110, Figure 1 For example, the height direction of the transverse mechanism 110 is... Figure 1 The direction pointed to by any arrow on the straight line S2.
[0052] Optionally, the first driving element 131 may be a motor, a cylinder, a hydraulic cylinder, or other driving device.
[0053] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The first driving component 131 is a cylinder. This simplifies operation, increases reliability, and improves the working stability of the first driving component 131. This embodiment only provides one specific implementation of the first driving component 131, but is not limited thereto.
[0054] Further, please refer to Figure 1 , Figure 2 and Figure 3 The deflector frame 132 is provided with a first contact portion 133 and a second contact portion 134. The first contact portion 133 and the second contact portion 134 are spaced apart on the deflector frame 132 and are respectively located at opposite ends of the rotating shaft 123. Both the first contact portion 133 and the second contact portion 134 abut against the pickup member 122, and the lengths of the first contact portion 133 and the second contact portion 134 are the same. Thus, in the initial state, the two pickup members 122 are arranged in a figure-eight shape under the action of the biasing member 124. When the flattening mechanism 130 deflects the pickup member 122, the cylinder extends, and the first contact portion 133 and the second contact portion 134 abut against both sides of the rotating shaft 123, so that the pickup member 122 slowly rotates from an inclined state to a horizontal state, thereby stably picking up the two battery cells 200. After being picked up, the cylinder retracts, and under the action of the biasing component 124, the two battery cells 200 return to the tilted state along with the two picking components 122, thus preparing for the subsequent casing insertion operation.
[0055] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The traversing mechanism 110 includes a traversing frame 111, a second driving member 112, and a transmission member 113. Both the second driving member 112 and the transmission member 113 are connected to the traversing frame 111. The second driving member 112 and the transmission member 113 are driven together, and the transmission member 113 is driven together with the pickup frame 121. Thus, the second driving member 112 provides the driving force, and the transmission member 113 provides the transmission force, causing the two pickup frames 121 to move closer to or further away from each other on the transmission member 113.
[0056] For the drive of the two pickup racks 121, two second drive components 112 and two transmission components 113 can be set, or one second drive component 112 and one transmission component 113 can be set, or two second drive components 112 and one transmission component 113 can be set.
[0057] Optionally, the second drive element 112 may be a motor, cylinder, hydraulic cylinder or other drive device.
[0058] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The second driving component 112 is a servo motor. This facilitates control, enhances reliability, and improves the motion accuracy of the pickup mechanism 120 on the transmission component 113. This embodiment only provides a specific implementation of the first driving component 131, but is not limited thereto.
[0059] Further, please refer to Figure 2 and Figure 3 The lateral movement mechanism 110 also includes a synchronous belt 114 and a transmission wheel 115. The second drive member 112 is connected to the transmission member 113 via the synchronous belt 114 and the transmission wheel 115. This improves the driving efficiency of the second drive member 112, facilitates the flexible installation of the second drive member 112, and enhances the structural compactness of the battery cell housing device 100.
[0060] In one embodiment, see Figure 3 The transverse mechanism 110 also includes a protective cover 116, which is disposed on the synchronous belt 114 and the drive pulley 115. This helps to protect the synchronous belt 114 and the drive pulley 115, and improves the working stability and safety of the transverse mechanism 110.
[0061] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The transmission component 113 includes a bidirectional threaded screw 1131 and a screw nut 1132. Two transverse guides 111 are respectively connected to the two screw nuts 1132, and the two screw nuts 1132 are respectively connected to two sets of oppositely oriented threads on the bidirectional threaded screw 1131. The second drive component 112 is used to drive the bidirectional threaded screw 1131 to rotate. Thus, through the transmission action of the bidirectional threaded screw 1131, the synchronization of the movement of the two pickup mechanisms 120 is improved, facilitating the positioning and pitch adjustment of the two battery cells 200, thereby improving the efficiency of battery cell 200 insertion into the casing.
[0062] In one embodiment, see Figure 1 , Figure 2 and Figure 3The battery cell insertion device 100 also includes a photoelectric sensor 140. Through the sensing function of the photoelectric sensor 140, it can sense whether the battery cell 200 is on the picking mechanism 120 and automatically detect whether the battery cell 200 has fallen off during the movement, thereby improving the working safety of the battery cell insertion device 100.
[0063] In one embodiment, see Figure 1 The transverse frame 111 is equipped with a first guide rail 118, and the deflection frame 132 is guided and engaged with the transverse frame 111 through the first guide rail 118. This improves both the transverse stability of the deflection frame 132 and the overall structural stability of the battery cell housing device 100.
[0064] In one embodiment, see Figure 1 and Figure 2 A second guide rail 119 is provided on the transverse frame 111, and the lead screw nut 1132 is guided and engaged with the transverse frame 111 through the second guide rail 119. In this way, on the one hand, it helps to improve the transverse stability of the picking mechanism 120. On the other hand, it helps to further improve the overall structural stability of the battery cell housing device 100.
[0065] In one embodiment, see Figure 1 The transverse movement mechanism 110 also includes a mounting flange 117. The transverse movement frame 111 is connected to the drive equipment via the mounting flange 117. This improves the ease of installation and connection stability between the transverse movement frame 111 and the drive equipment.
[0066] A battery production system, please refer to Figure 1 It includes a drive device and a cell housing device 100 of any one of the above, wherein the drive device is connected to the transverse movement mechanism 110.
[0067] In the aforementioned battery production system, during operation, firstly, a driving device such as a robotic arm or motion platform moves the cell loading device 100 to the loading station. At this time, the picking component 122 is tilted relative to the horizontal direction. The flattening mechanism 130 drives the picking component 122 to rotate around the rotating shaft 123, making the picking component 122 horizontal. After deflection, the picking component 122 approaches and picks up the cell 200. After picking up, the driving device lifts the cell 200. At this time, the flattening mechanism 130 releases its force, and the picking component 122 returns to its initial state, causing the cell 200 to tilt relative to the length direction of the transverse movement mechanism 110. The driving component moves the cell 200 above the casing 300. Then, the transverse movement mechanism 110 adjusts the cell 200... The horizontal position of the battery cell 200 is such that it is in the preset housing position. Then, the robotic arm moves the battery cell housing device 100 downward, so that the end of the battery cell 200 near the housing 300 first contacts the inner edge of the housing 300. After contact, the battery cell housing device 100 continues to move downward, and the battery cell 200 begins to rotate due to the external force. The horizontal position of the battery cell 200 is adjusted by the action of the horizontal movement mechanism 110, so that the battery cell 200 always moves close to the edge of the housing 300 during the pressing process. At this time, the battery cell 200 performs a fan-shaped rotation with the edge of the housing 300 as the rotation axis. Finally, the bottom of the battery cell 200 is flat with the bottom of the housing 300, the battery cell 200 is installed in the housing, and the pickup 122 releases the battery cell 200 and resets. The battery cell insertion device 100 descends at an angle to the housing 300 during insertion, and the horizontal position of the battery cell 200 is adjusted by the horizontal movement mechanism 110, so that the battery cell 200 is inserted into the housing first at one end and then completely inserted into the housing. This helps to improve the insertion efficiency and avoids damage to the battery cell 200 by the edge of the housing 300, thereby improving the reliability of the automatic insertion of the battery cell 200.
