[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on Chinese patent application number 202420450184.0, application date March 8, 2024, and invention name “A battery shell insertion device”, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into the present disclosure as a reference. Technical Field

[0003] The present disclosure relates to the technical field of battery production, and in particular to a battery shell insertion device. Background Art

[0004] This section is intended to provide a background or context for the embodiments of the present disclosure. No admission is made that the description herein is prior art by virtue of its inclusion in this section.

[0005] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in energy storage fields.

[0006] In the battery cell production process, a bare cell is placed into a casing and the top cover is closed to obtain a shelled cell. However, in the related art, during the production process of placing bare cells into casings, the front and back of the casing are usually detected on a transfer positioning platform, which affects the cycle time. Moreover, if the casing is placed upside down, the equipment needs to alarm and shut down, which reduces the cycle time and production efficiency.

[0007] Summary of the Invention

[0008] In view of this, the embodiments of the present disclosure hope to provide a battery shell insertion device that can improve the production efficiency of battery cells.

[0009] To achieve the above objectives, the present disclosure provides a battery shell insertion device, comprising:

[0010] control equipment;

[0011] Loading station, used to store the shells to be tested;

[0012] Transfer station, used to store shells that have passed the inspection;

[0013] The transfer mechanism includes a manipulator having a suction member and a detection mechanism provided on the manipulator, wherein the control device controls the suction member to absorb the shell on the loading station and controls the detection mechanism to detect the state of the shell on the suction member, wherein the state of the shell includes a first state and a second state, and the first state is different from the second state;

[0014] When the shell is in the first state, the control device controls the manipulator to transfer the shell to the transfer station.

[0015] The battery shell insertion equipment provided by the embodiment of the present disclosure, on the one hand, by arranging a detection mechanism on the manipulator, the control device controls the adsorption part of the manipulator to absorb the shell on the loading station, and controls the detection mechanism to detect the state of the shell on the adsorption part. The detection mechanism detects the state of the shell on the adsorption part, and can detect the state of the shell on the transfer mechanism. If the detection mechanism detects that the shell is in the first state, the control device can directly control the manipulator to transfer the shell to the transfer station, without first transferring the shell to the transfer station through the transfer mechanism and then detecting the state of the shell. The battery shell insertion equipment does not need to alarm and shut down, which improves the beat and thus improves production efficiency.

[0016] In some embodiments, the transfer mechanism includes a first rotating mechanism, the first rotating mechanism being configured to drive the housing on the adsorption member to rotate in a preset direction and at a preset angle, wherein a rotation axis of the housing rotating in the preset direction is parallel to a bottom wall of the housing;

[0017] When the housing is in the first state, the housing is rotated 90° in a preset direction, and the bottom wall of the housing faces the detection mechanism;

[0018] When the shell is in the second state, after the shell is rotated 90 degrees in a preset direction, the opening at the top of the shell faces the detection mechanism.

[0019] The control device controls the detection mechanism to detect the state of the shell on the adsorption part. If the detection mechanism detects the bottom wall of the shell within the preset range (excluding the bottom wall detected by the detection mechanism through the opening of the shell), it means that the shell is in the first state and the detection is qualified. The control device controls the manipulator to transfer the shell in the first state to the transfer station. If the shell is in the second state, after the shell rotates 90° in the preset direction, the opening at the top of the shell faces the detection mechanism. At this time, the detection mechanism can only detect the opening of the shell within the preset range, and cannot detect the bottom wall of the shell, which means that the shell is in the second state and the detection is unqualified. The control device controls the correction mechanism to switch the shell in the second state from the second state to the first state, and controls the manipulator to transfer the shell switched to the first state to the transfer station.

[0020] In some embodiments, the battery shell insertion device further includes a correction mechanism for switching the shell from the second state to the first state.

[0021] Here, a detection mechanism is provided on the manipulator, and a control device controls the detection mechanism to detect the state of the housing on the suction member. If the detection mechanism detects that the housing is in the first state, it indicates that the test has passed, and the control device controls the manipulator to transfer the housing in the first state to the transfer station. If the detection mechanism detects that the housing is in the second state, it indicates that the test has failed, and the control device controls the correction mechanism to switch the housing from the second state to the first state, and controls the manipulator to transfer the housing in the first state to the transfer station. On the one hand, by providing the detection mechanism on the manipulator, the control device controls the manipulator's suction member to pick up the housing from the loading station, eliminating the need to first transfer the housing to the transfer station via the transfer mechanism and then perform a condition check on the housing. This eliminates the need for an alarm to shut down the battery shell insertion equipment, improving cycle time and thus increasing production efficiency. On the other hand, by providing the correction mechanism, the control device can control the correction mechanism to switch the housing from the second state to the first state, automatically correcting incoming housings that have been placed upside down, without the need for an alarm to shut down the machine or manual intervention, further improving production efficiency and increasing the output of each unit.

[0022] In some embodiments, the correction mechanism is provided on the manipulator for switching the shell on the adsorption component from the second state to the first state.

[0023] Here, by setting the correction mechanism on the robot, when the detection mechanism detects that the shell is in the second state, the correction mechanism can directly switch the shell on the adsorption part from the second state to the first state on the robot. The robot does not need to place the shell elsewhere and then correct the state of the shell, which reduces the steps, improves the beat, further improves production efficiency, and increases the output of a single machine.

[0024] In some embodiments, the correction mechanism includes a carrier. When the shell is in the second state, the control device controls the manipulator to transfer the shell to the carrier, and controls the shell on the carrier to switch from the second state to the first state.

[0025] The control device controls the manipulator to transfer the shell to the carrier, and controls the shell on the carrier to switch from the second state to the first state. That is to say, the correction mechanism is not set on the manipulator. By setting the correction mechanism and the manipulator separately, the structure and drive coordination are simplified, which is conducive to improving the reliability and stability of the battery shell entry equipment.

[0026] In some embodiments, the correction mechanism further includes a second rotation mechanism, which is used to drive the shell on the carrier to rotate 180°, so that the shell on the carrier switches from the second state to the first state.

[0027] The correction mechanism is provided with a second rotation mechanism, which drives the shell on the carrier to rotate 180 degrees through the second rotation mechanism, so that the shell on the carrier switches from the second state to the first state. The structure is simple and reliable.

[0028] In some embodiments, the control device controls the robot to transfer the shell in the correction mechanism that is in the first state to the transfer station.

[0029] Here, the control device controls the correction mechanism to switch the shell in the second state from the second state to the first state, and then controls the robot to transfer the shell switched to the first state to the transfer station, thereby realizing the automation of the shell correction process, reducing labor costs and improving production efficiency.

[0030] In some embodiments, the supporting member is a sponge suction cup.

[0031] Thus, on the one hand, even if there are unevenness on the housing, the housing can be kept relatively flat when placed on the sponge suction cup, and damage to the housing can be reduced to a certain extent. On the other hand, the sponge suction cup can exert a certain adsorption force on the housing, reducing the relative displacement between the housing and the sponge suction cup, and making the housing more stably placed on the correction mechanism.

[0032] In some embodiments, the correction mechanism further includes a guide block disposed on a circumferential side of the carrier, for guiding the housing onto the carrier.

[0033] On the one hand, it can be used to guide the shell onto the carrier, which is beneficial for the manipulator to transfer the shell in the second state to the carrier. On the other hand, it can limit the shell on the carrier, further improving the reliability of the correction process.

[0034] In some embodiments, the second rotating mechanism is a rotating cylinder.

[0035] In this way, the control is simple and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] With the development of clean energy, more and more devices use electricity as a driving force. Consequently, power batteries, such as lithium-ion batteries, that can store large amounts of electricity and undergo multiple charge and discharge cycles are experiencing rapid development. These batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in aerospace and other fields. As the application areas of power batteries continue to expand, market demand is also growing.

[0050] In the embodiment of the present disclosure, the battery cell may be a battery cell. A battery cell refers to a basic unit that can realize the mutual conversion between chemical energy and electrical energy, and can be used to make a battery module or battery pack, thereby being used to supply power to an electrical device. A battery cell may be a primary battery or a secondary battery. A secondary battery refers to a battery cell that can be activated by charging the active material after the battery cell is discharged and can continue to be used. The battery cell may be a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, or a lead-acid battery, etc., and the embodiment of the present disclosure is not limited to this. The battery cell may be cylindrical, rectangular, or in other shapes. It will be understood that the battery cell in the embodiment of the present disclosure refers to a battery cell in the form of a rectangular parallelepiped.

[0051] A battery cell includes an electrode assembly and an electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell primarily operates by the movement of metal ions between the positive and negative electrode sheets. The positive electrode sheet includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive electrode collector. The uncoated positive electrode collector protrudes from the coated positive electrode collector, and the uncoated positive electrode collector serves as the positive electrode tab. For lithium-ion batteries, for example, the positive electrode current collector can be made of aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode sheet includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative electrode collector. The uncoated negative electrode collector protrudes from the coated negative electrode collector, and the uncoated negative electrode collector serves as the negative electrode tab. The negative electrode current collector can be made of copper, and the negative electrode active material can be carbon or silicon. To ensure high current flow without melting, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together. The separator can be made of materials such as PP (polypropylene) or PE (polyethylene).

[0052] The battery cell also includes a packaging film and a shell. The packaging film is applied to the outside of the electrode assembly, and the shell encapsulates the electrode assembly (i.e., the bare cell) coated with the packaging film to form a battery cell. For example, the packaging film can be Mylar film, and the shell can be an aluminum shell or steel shell. After the electrode assembly is wound and formed, the Mylar film and shell are encapsulated through the Mylar wrapping process and the shell insertion process. The Mylar film seals and protects the electrode assembly, and the Mylar film can effectively insulate the electrode assembly and the shell from each other, preventing internal short circuits in the battery cell. The shell also plays a protective role.

[0053] In the battery shell production process, the battery is placed in the shell and the top cover is closed to obtain the shelled battery. However, in the related art, during the battery shell production process, the shell is usually detected on the transfer positioning platform, which affects the cycle time. Moreover, if the shell is placed upside down, the equipment needs to alarm and shut down, which reduces the cycle time and thus reduces production efficiency.

[0054] The embodiment of the present disclosure provides a battery shell insertion device 10. As shown in Figures 1 to 4, the battery shell insertion device 10 includes a control device, a loading station 1, a transfer station 2 and a transfer mechanism 4. The loading station 1 is used to store the shells 20 to be inspected. The transfer station 2 is used to store the shells 20 that have passed the inspection. The transfer mechanism 4 includes a manipulator 41 with an adsorption member 42 and a detection mechanism 43 provided on the manipulator 41. The control device controls the adsorption member 42 to absorb the shell 20 on the loading station 1, and controls the detection mechanism 43 to detect the state of the shell 20 on the adsorption member 42. The state of the shell 20 includes a first state and a second state. The first state is different from the second state. When the shell 20 is in the first state, the control device controls the manipulator 41 to transfer the shell 20 to the transfer station 2.

[0055] The battery shell insertion device 10 includes one or more transfer mechanisms 4, that is, the battery shell insertion device 10 can have only one transfer mechanism 4 or multiple transfer mechanisms 4. In the case where there are multiple transfer mechanisms 4, multiple transfer mechanisms 4 can transfer the shell 20 at the same time, thereby improving production efficiency.

[0056] It should be noted that the multiple mentioned in the embodiments of the present disclosure refers to a number of two or more.

[0057] The loading station 1 is used to store the shell 20 to be inspected, where "to be inspected" refers to the state of the shell 20 to be confirmed.

[0058] Here, the state of the housing 20 includes a first state and a second state. That is, the housing 20 in the loading station 1 is either in the first state or in the second state.

[0059] It should be noted that the transfer station 2 is used to store the shell 20 that has passed the inspection, that is, passing the inspection means that the shell 20 is in the first state, that is, the transfer station 2 is used to store the shell 20 in the first state.

[0060] The transfer mechanism 4 includes a manipulator 41 having a suction member 42 and a detection mechanism 43 provided on the manipulator 41. The control device controls the suction member 42 to suck the shell 20 on the loading station 1 and controls the detection mechanism 43 to detect the status of the shell 20 on the suction member 42.

[0061] Illustratively, the battery shell insertion device 10 includes a control device (not shown) for controlling the operation of the detection mechanism 43 of the transfer mechanism 4, the manipulator 41, and the like. The control device may include, but is not limited to, at least one of an industrial computer, a programmable logic controller (PLC), and a host computer. The host computer may be, for example, a server, a laptop computer, a tablet computer, a desktop computer, or a smartphone.

[0062] The specific type of the detection mechanism 43 is not limited here, and can be, for example, a proximity or diffuse photoelectric detection system, a CCD visual detection system, and the like.

[0063] The control device controls the adsorption member 42 to absorb the shell 20 on the loading station 1, and controls the detection mechanism 43 to detect the state of the shell 20 on the adsorption member 42. The detection mechanism 43 is provided on the manipulator 41, which can better detect the shell 20 absorbed by the adsorption member 42.

[0064] In some embodiments, there may be multiple adsorption components 42 , and each adsorption component 42 may correspond to one detection mechanism 43 .

[0065] In some embodiments, referring to FIG. 2 and FIG. 3 , a plurality of detection mechanisms 43 can independently detect the status of the housing 20 on a plurality of adsorption members 42 .

[0066] In some embodiments, multiple detection mechanisms 43 can detect the shells 20 on multiple adsorbents 42 in parallel and in a coordinated manner. For example, the manipulator 41 includes a first adsorbent 42 and a second adsorbent 42, and the shells 20 on the first adsorbent 42 and the second adsorbent 42 are in place at the same time; in response to detecting that the shell 20 is sucked onto the first adsorbent 42 and the second adsorbent 42, the PLC can send a first trigger signal to the detection mechanism 43 corresponding to the first adsorbent 42 and the detection mechanism 43 corresponding to the second adsorbent 42, thereby detecting the shell 20 on the first adsorbent 42 using the detection mechanism 43 corresponding to the first adsorbent 42 in parallel to obtain the detection result of the shell 20, and detecting the shell 20 on the second adsorbent 42 using the detection mechanism 43 corresponding to the second adsorbent 42 to obtain the detection result of the shell 20.

[0067] The battery shell insertion device 10 provided by the embodiment of the present disclosure, on the one hand, by arranging a detection mechanism 43 on the manipulator 41, the control device controls the adsorption part 42 of the manipulator 41 to absorb the shell 20 on the loading station 1, and controls the detection mechanism 43 to detect the state of the shell 20 on the adsorption part 42. The detection mechanism 43 detects the state of the shell 20 on the adsorption part 42, and the state of the shell 20 can be detected on the transfer mechanism 4. If the detection mechanism 43 detects that the shell 20 is in the first state, the control device can directly control the manipulator 41 to transfer the shell 20 to the transfer station 2, without first transferring the shell 20 to the transfer station 2 through the transfer mechanism 4 and then detecting the state of the shell 20. The battery shell insertion device 10 does not need to alarm and shut down, which improves the beat and thus improves production efficiency.

[0068] In some embodiments, referring to FIG. 1 and FIG. 4 , the battery shell insertion device 10 further includes a correction mechanism 3 for switching the shell 20 from the second state to the first state.

[0069] Here, by providing a detection mechanism 43 on the manipulator 41, the control device controls the detection mechanism 43 to detect the state of the housing 20 on the suction member 42. If the detection mechanism 43 detects that the housing 20 is in the first state, it indicates that the test has passed, and the control device controls the manipulator 41 to transfer the housing 20 in the first state to the transfer station 2. If the detection mechanism 43 detects that the housing 20 is in the second state, it indicates that the test has failed, and the control device controls the correction mechanism 3 to switch the housing 20 in the second state from the second state to the first state, and controls the manipulator 41 to transfer the housing 20 in the first state to the transfer station 2. On the one hand, by providing the detection mechanism 43 on the manipulator 41, the control device controls the suction member 42 of the manipulator 41 to absorb the housing 20 from the loading station 1, eliminating the need to first transfer the housing 20 to the transfer station 2 via the transfer mechanism 4 and then test the state of the housing 20. This eliminates the need for the battery shell insertion equipment 10 to alarm and shut down, thereby improving cycle time and thus increasing production efficiency. On the other hand, by setting up the correction mechanism 3, the shell 20 in the second state can be switched from the second state to the first state through the control device to realize automatic correction of the shell 20 that is placed upside down, without the need for alarm shutdown or manual intervention, further improving production efficiency and increasing the output of a single machine.

[0070] In some embodiments, referring to Figures 2 and 3 , the transfer mechanism 4 further includes a first rotation mechanism 44, which is configured to rotate the housing 20 on the adsorption member 42 in a predetermined direction and by a predetermined angle, wherein the rotation axis of the housing 20 in the predetermined direction is parallel to the bottom wall of the housing 20. When the housing 20 is in the first state, after the housing 20 rotates 90° in the predetermined direction, the bottom wall of the housing 20 faces the detection mechanism 43. When the housing 20 is in the second state, after the housing 20 rotates 90° in the predetermined direction, the opening at the top of the housing 20 faces the detection mechanism 43.

[0071] In the prior art, for the stability and convenience of incoming materials, the shell 20 is stored in a flat form in the loading station 1. For the subsequent shell insertion step, the shell 20 lying flat in the loading station 1 needs to be rotated 90° in a preset direction through the transfer mechanism 4 so that the opening at the top of the shell 20 faces downward and the bottom wall of the shell 20 faces upward and is placed on the transfer station 2.

[0072] If the control device controls the first rotating mechanism 44 to drive the shell 20 on the adsorption component 42 to rotate 90° in the preset direction, and the bottom wall of the shell 20 faces the detection mechanism 43, it means that the shell 20 is in the first state.

[0073] If the control device controls the first rotating mechanism 44 to drive the shell 20 on the adsorption component 42 to rotate 90° in the preset direction, and the opening on the top of the shell 20 faces the detection mechanism 43, it means that the shell 20 is in the second state.

[0074] Here, the preset direction is not limited and can be clockwise or counterclockwise.

[0075] Specifically, the control device controls the detection mechanism 43 to detect the state of the shell 20 on the adsorption member 42. If the detection mechanism 43 detects the bottom wall of the shell 20 within the preset range (excluding the bottom wall detected by the detection mechanism 43 through the opening of the shell 20), it means that the shell 20 is in the first state and the detection is qualified. The control device controls the manipulator 41 to transfer the shell 20 in the first state to the transfer station 2. If the shell 20 is in the second state, after the shell 20 rotates 90° in the preset direction, the opening at the top of the shell 20 faces the detection mechanism 43. At this time, the detection mechanism 43 can only detect the opening of the shell 20 within the preset range, and cannot detect the bottom wall of the shell 20, which means that the shell 20 is in the second state and the detection is unqualified. The control device controls the correction mechanism 3 to switch the shell 20 in the second state from the second state to the first state, and controls the manipulator 41 to transfer the shell 20 switched to the first state to the transfer station 2.

[0076] It should be noted that the specific type and location of the correction mechanism 3 are not limited here.

[0077] In some embodiments, the correction mechanism 3 is disposed on the manipulator 41 and is used to switch the housing 20 on the adsorption component 42 from the second state to the first state.

[0078] Here, by setting the correction mechanism 3 on the manipulator 41, when the detection mechanism 43 detects that the shell 20 is in the second state, the correction mechanism 3 can directly switch the shell 20 on the adsorption part 42 from the second state to the first state on the manipulator 41. The manipulator 41 does not need to place the shell 20 elsewhere and then correct the state of the shell 20, which reduces the steps, improves the beat, further improves the production efficiency, and increases the output of a single machine.

[0079] In some embodiments, referring to Figures 1 to 4, the correction mechanism 3 includes a carrier 31. When the shell 20 is in the second state, the control device controls the manipulator 41 to transfer the shell 20 to the carrier 31, and controls the shell 20 on the carrier 31 to switch from the second state to the first state.

[0080] Here, the correction mechanism 3 is not provided on the manipulator 41 . The correction mechanism 3 is provided with a carrier 31 , and the carrier 31 is used to support the housing 20 in the second state and then perform correction.

[0081] There are many ways to control the shell 20 on the carrier 31 to switch from the second state to the first state. You can directly operate the shell 20 to switch the shell 20 from the second state to the first state; you can also operate the carrier 31 to switch the shell 20 from the second state to the first state.

[0082] The control device controls the manipulator 41 to transfer the shell 20 to the carrier 31, and controls the shell 20 on the carrier 31 to switch from the second state to the first state. That is to say, the correction mechanism 3 is not arranged on the manipulator 41. By setting the correction mechanism 3 and the manipulator 41 separately, the structure and drive coordination are simplified, which is conducive to improving the reliability and stability of the battery shell entry device 10.

[0083] In some embodiments, referring to FIG. 4 , the correction mechanism 3 further includes a second rotation mechanism 32 , which is configured to drive the housing 20 on the carrier 31 to rotate 180°, so that the housing 20 on the carrier 31 switches from the second state to the first state.

[0084] The specific type of the second rotating mechanism 32 is not limited here, and can be, for example, a rotating cylinder.

[0085] Here, the second rotating mechanism 32 can drive the shell 20 to rotate 180° by directly driving the shell 20 or by driving the carrier 31 to rotate 180°, so as to switch the shell 20 on the carrier 31 from the second state to the first state.

[0086] The correction mechanism 3 is provided with a second rotation mechanism 32, which drives the housing 20 on the carrier 31 to rotate 180 degrees, so that the housing 20 on the carrier 31 switches from the second state to the first state. This structure is simple and reliable.

[0087] In some embodiments, referring to FIG. 1 , the control device controls the manipulator 41 to transfer the housing 20 in the correction mechanism 3 that is in the first state to the transfer station 2 .

[0088] Here, the control device controls the correction mechanism 3 to switch the shell 20 in the second state from the second state to the first state, and then controls the manipulator 41 to transfer the shell 20 switched to the first state to the transfer station 2, thereby realizing the automation of the correction process of the shell 20, reducing labor costs and improving production efficiency.

[0089] It should be noted that the specific type of the carrier 31 is not limited here, and can be, for example, a suction cup or a simple carrier plate.

[0090] In some embodiments, the supporting member 31 is a sponge suction cup.

[0091] The sponge suction cup itself has a certain degree of elasticity and can generate a certain amount of adsorption force. Thus, on the one hand, even if there are uneven surfaces on the housing 20, when the housing 20 is placed on the sponge suction cup, the housing 20 can be kept relatively flat, and damage to the housing 20 can be reduced to a certain extent. On the other hand, the sponge suction cup can generate a certain amount of adsorption force on the housing 20, reducing the relative displacement between the housing 20 and the sponge suction cup, and making the housing 20 more stably placed on the correction mechanism 3.

[0092] In some embodiments, referring to FIG. 4 , the correction mechanism 3 further includes a guide block 33 disposed on a circumferential side of the carrier 31 for guiding the housing 20 onto the carrier 31 .

[0093] The specific structure and shape of the guide block 33 are not limited here, as long as it can guide the housing 20.

[0094] The specific number of the guide blocks 33 is not limited here, and can be one or more. When there are more than one guide blocks 33 , the guide blocks 33 are spaced apart along the circumference of the carrier 31 .

[0095] Exemplarily, a guide surface is provided on a side of the guide block 33 facing the carrier 31 .

[0096] The correction mechanism 3 is provided with guide blocks 33 on the circumference of the carrier 31. On the one hand, it can be used to guide the housing 20 onto the carrier 31, which facilitates the manipulator 41 to transfer the housing 20 in the second state to the carrier 31. On the other hand, it can limit the position of the housing 20 on the carrier 31, further improving the reliability of the correction process.

[0097] For example, the detection mechanism 43 detects that the housing 20 is in the second state, and controls the manipulator 41 through the control device to transfer the housing 20 to the recycling station. In other words, the housing 20 in the second state is recycled without correction, thereby improving production efficiency.

[0098] Exemplarily, the implementation process of inserting a bare cell into a shell includes the following steps:

[0099] Step S801: The control device controls the transfer mechanism 4 to take the shell 20 from the loading station 1;

[0100] In step S802, the control device controls the suction member 42 of the transfer mechanism 4 to absorb the housing 20. After the manipulator 41 moves to an appropriate position, the control device controls the first rotation mechanism 44 of the transfer mechanism 4 to rotate the housing 20 on the suction member 42 in a predetermined direction and by a predetermined angle. The control device controls the detection mechanism 43 to detect the status of the housing 20 on the suction member 42.

[0101] Step S803 , the detection mechanism 43 detects that the housing 20 is in the first state, and the control device controls the manipulator 41 to transfer the housing 20 in the first state to the transfer station 2 ;

[0102] In step S804, the detection mechanism 43 detects that the shell 20 is in the second state, and controls the manipulator 41 through the control device to transfer the shell 20 to the carrier 31 of the correction mechanism 3. The control device controls the correction mechanism 3 to switch the shell 20 in the second state from the second state to the first state, and then controls the manipulator 41 to transfer the shell 20 switched to the first state to the transfer station 2.
