[0032] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0033] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0034] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0035] like Figures 1 to 3 As shown, the present invention provides a battery core shell insertion device, comprising a steel shell fixture 1 and a core lifting mechanism. The steel shell fixture 1 comprises a body 101 and a baffle 103 disposed below the body 101. The body 101 is used to absorb the steel shell 100. The body 101 is provided with a steel shell placement position 102. The baffle 103 can switch between a first position and a second position. When the baffle 103 is in the first position, the baffle 103 does not protrude from the steel shell placement position 102, allowing the shelled core 200 to enter the steel shell 100 from below. When the baffle 103 is in the second position, the baffle 103 protrudes from the steel shell placement position 102 to block the open end of the steel shell 100, thereby preventing the shelled core 200 from falling off the bottom of the steel shell 100. The core lifting mechanism is located below the steel shell clamp 1. The core lifting mechanism includes a core clamp 2 and an upper top assembly 3. The core clamp 2 is provided with a core placement position opposite to the steel shell placement position 102. The upper top assembly 3 includes a first driving member 301 and an upper head 302 for pushing the core 200 upward. The upper head 302 is connected to the first driving member 301. The first driving member 301 can drive the upper head 302 to move upward in the vertical direction so that the core 200 enters the interior of the steel shell 100 from bottom to top. When the core 200 enters the interior of the steel shell 100, the baffle 103 switches from the first position to the second position to block the core 200 inside the steel shell 100.

[0036] The steel shell 100 is a structure with one end open and the other end closed. In this embodiment, the steel shell 100 is adsorbed in the steel shell clamp 1 through the main body 101 with its open end facing downward and the sealed end facing upward. At this time, the baffle 103 is in the first position, so that the steel shell placement position 102 is connected with the core placement position, and the core 200 is placed in the core placement position through the core clamp 2. The first driving member 301 drives the upper head 302 to move upward, and drives the upper head 302 to push the core 200 from bottom to top into the interior of the steel shell 100. Then, the baffle 103 switches from the first position to the second position, and the core 200 after entering the shell is blocked inside the steel shell 100 by the baffle 103. Different from the prior art method of placing the core 200 into the steel shell 100 from top to bottom, the battery core shell insertion device in the present application pushes the core 200 into the steel shell 100 from bottom to top with the cooperation of the upper top component 3 and the baffle 103, preventing the core 200 from being damaged by the steel shell 100 during shell insertion, thereby improving the battery yield.

[0037] Continue to refer to Figures 1 to 3 , Figure 1 and Figure 3 The large arrow in the figure indicates the direction of rotation of the first turntable 20. The battery core shell insertion device also includes a first turntable 20 that can rotate about a set axis. Multiple steel shell clamps 1 and core lifting mechanisms are provided. Along the direction of rotation of the first turntable 20, each steel shell clamp 1 is evenly and spaced apart on the top of the first turntable 20. The core lifting mechanisms correspond to each steel shell clamp 1 one-to-one, and each steel shell clamp 1 and core lifting mechanism rotate synchronously with the first turntable 20. The core lifting mechanism is located below the first turntable 20. The first turntable 20 is provided with through holes extending through its top and bottom. The steel shell placement position 102 and the core placement position are both aligned with the through holes, and the through holes can pass through the core 200 to be inserted into the shell. Multiple steel shell clamps 1 are provided on the first turntable 20, each with a corresponding core lifting mechanism. This design enables the simultaneous insertion of multiple cores 200, improving the efficiency of inserting the cores 200 into the shell. In addition, all the steel shell clamps 1 are driven to rotate by the first turntable 20, and each steel shell clamp 1 is set on the top of the first turntable 20. The first turntable 20 is used to concentrate each steel shell clamp 1 into a whole, so that the structure of the battery roll core shell device is more compact, and it is convenient to transfer the steel shell 100 on the steel shell clamp 1 through the first turntable 20.

[0038] Reference Figure 3 、 Figure 4 and Figure 6The upper assembly 3 further includes a first cam 303 and a first guide wheel 304. The first cam 303 is fixedly arranged below the first turntable 20 and is coaxial with the first turntable 20. The first guide wheel 304 is arranged at the lower end of the first driving member 301. The first cam 303 is provided with a first guide surface 3031 around its circumference. The first guide surface 3031 is provided for the first guide wheel 304 to roll. The first guide surface 3031 is provided with a first section 30311 and a first section 30312. The first section 30311 is located at the lowest position of the first guide surface 3031, and the second section 30312 is located at the highest position of the first guide surface 3031. The first section 30311 and the second section 30312 are sequentially arranged along the rotation direction of the first turntable 20. When the first guide wheel 304 rolls from the first section 30311 to the second section 30312, the first driving member 301 drives the upper jack 302 upward to push the winding core 200 into the interior of the steel shell 100. The first guide surface 3031 is annular in structure. As the winding core lifting mechanism rotates with the first turntable 20, the first guide wheel 304 rolls back and forth along the extension direction of the first guide surface 3031. When the first guide wheel 304 rolls from the first section 30311 to the second section 30312, under the action of the first guide wheel 304, the first push rod 3012 drives the upper head 302 to rise, so that the upper head 302 pushes the core 200 into the steel shell 100. After the core 200 enters the shell, the first guide wheel 304 continues to roll along the extension direction of the first guide surface 3031. After the first guide wheel 304 rolls around the first guide surface 3031 for one circle, the first guide wheel 304 returns to the first section 30311, driving the upper head 302 to descend and reset.

[0039] Reference Figure 6 To ensure smooth rolling of the first guide wheel 304 on the first guide surface 3031, a first transition section 30313 and a second transition section 30314 are provided on the first guide surface 3031. The first transition section 30313 and the second transition section 30314 are disposed between the first section 30311 and the second section 30312. Along the rotation direction of the first turntable 20, the first section 30311, the first transition section 30313, the second section 30312, and the second transition section 30314 are sequentially arranged, so that the first section 30311, the first transition section 30313, the second section 30312, and the second transition section 30314 surround the annular first guide surface 3031. Along the rotation direction of the first turntable 20, the first transition section 30313 is inclined upward, and the second transition section 30314 is inclined downward.

[0040] Continue to refer to Figure 6A first limiting member 305 is fixedly provided above the first cam 303, and a first limiting surface parallel to the first guide surface 3031 is provided at the bottom of the first limiting surface. The upper side of the first guide wheel 304 abuts against the first limiting surface, and the lower side of the first guide wheel 304 abuts against the first guide surface 3031.

[0041] In this example, the first stopper 305 extends from the second section 30312 to the first section 30311 along the rotation direction of the first turntable 20. Because the winding core 200 must pass through the first turntable 20 to enter the steel shell 100, the height difference between the first section 30311 and the second section 30312 is relatively large. This arrangement of the first stopper 305 mitigates the rolling jolting of the first guide wheel 304 and ensures a smooth return of the upper ejector 302. The first cam 303 and the first stopper 305 are fixed by a fixing member 11, thereby integrally connecting the two.

[0042] Reference Figure 3 The core lifting mechanism also includes a second turntable 21 spaced apart and disposed below the first turntable 20. The second turntable 21 is coaxial with the first turntable 20 and rotates synchronously with the first turntable 20. The core clamp 2 includes a connecting rod 201 and a clamp head 202 disposed on the connecting rod 201. The clamp head 202 is located at the upper end of the connecting rod 201. The lower end of the connecting rod 201 extends from the top of the second turntable 21 to the bottom of the second turntable 21. The clamp head 202 is used to place the core 200. The first driving member 301 is connected to the connecting rod 201 via a first connecting block 3011, and the first connecting block 3011 can be raised and lowered relative to the connecting rod 201. The first connecting block 3011 connects the first driving member 301 and the connecting rod 201 into a whole. Since the connecting rod 201 passes through the second turntable 21, when the second turntable 21 rotates synchronously with the first turntable 20, the connecting rod 201 and the first driving member 301 rotate with the second turntable 21, thereby driving the first driving member 301 to rotate synchronously with the first turntable 20, thereby realizing the synchronous rotation of the clamp head 202 and the upper head 302 on the first turntable 20 of the steel shell clamp 1. No matter how the first turntable 20 rotates, it can ensure that the steel shell placement position 102 is opposite to the winding core placement position.

[0043] Reference Figure 3 and Figure 4 The first driving member 301 includes a first push rod 3012 and a support plate 3013 arranged below the first push rod 3012. The first push rod 3012 is arranged above the support plate 3013. The first push rod 3012 and the support plate 3013 are connected by a first connecting block 3011. The upper head 302 is arranged at one end of the first push rod 3012 away from the first connecting plate, and the first guide wheel 304 is arranged at one end of the support plate 3013 away from the first connecting block 3011.

[0044] Continue to refer to Figure 3 and Figure 4 The clamp head 202 includes a support plate 2021, a limit block 2022 and a second connecting block 2023. The support plate 2021 is located below the limit block 2022, and the support plate 2021 protrudes toward the outside of the first turntable 20 to form a support portion 20211. The support portion 20211 is used to support the support cup 300 that supports the core 200. The support portion 20211 is penetrated by an avoidance hole 20212, and the avoidance hole 20212 is used to avoid the upper head 302. The limit block 2022 is recessed on one side toward the outside of the first turntable 20 to form a limit groove 20221. The limit groove 20221 is a position for placing the core. The limit block 2022 is connected to the support plate 2021 through the first connecting block 3011, and the top of the connecting rod 201 passes through the second connecting block 2023. As will be appreciated, to prevent wear and tear on the core 200 during transport, the core 200 is typically placed within a support cup 300, which supports the core 200. The support cup 300 is cylindrical in structure, with a recessed receiving groove formed in the top. The bottom of the groove is provided with an opening, forming a stepped structure between the opening and the groove. When the core 200 is placed within the support cup 300, one end of the core 200 abuts against the stepped structure, while the other end extends out of the support cup 300 through the notch of the groove. In this embodiment, the winding core 200 is carried inside the support cup 300, with the bottom of the support cup 300 abutting against the support portion 20211, and the opening on the support cup 300 facing the avoidance hole 20212 of the support portion 20211. The hole wall of the limiting groove 20221 abuts against the outer wall of the support cup 300. The limiting block 2022 provides a limiting and supporting function for the support cup 300, preventing the support cup 300 from tilting on the support portion 20211. When the first push rod 3012 drives the upper push head 302 to move upward, the upper push head 302 sequentially passes through the avoidance hole 20212 and the opening to push the winding core 200 inside the support cup 300, causing the winding core 200 to move upward from bottom to enter the interior of the steel shell 100.

[0045] As a preferred solution, refer to Figure 3The battery core shell insertion device also includes a second cam 4 fixed below the first turntable 20. The second cam 4 is coaxial with the first turntable 20 and the first cam 303. A second guide wheel 306 is provided at the bottom of the connecting rod 201. The second cam 4 is provided with a second guide surface 401 around its circumference for the second guide wheel 306 to roll. A third section 4011 and a fourth section 4012 are provided on the second guide surface 401. The fourth section 4012 is located at the highest position of the second guide surface 401, and the third section 4011 is located at the lowest position of the second guide surface 401. The height difference between the third section 4011 and the fourth section 4012 is smaller than the height difference between the first section 30311 and the second section 30312. Along the rotation direction of the first turntable 20, the third section 4011 and the fourth section 4012 are distributed in sequence. When the second guide wheel 306 rolls from the third section 4011 to the fourth section 4012, the connecting rod 201 drives the support cup 300 and the winding core 200 to rise through the clamp head 202. Since the third section 4011 is located at the lowest position of the second guide surface 401 and the fourth section 4012 is located at the highest position of the second guide surface 401, when the second guide wheel 306 rolls from the third section 4011 to the fourth section 4012, the second guide wheel 306 drives the second link to rise, thereby driving the cup 300 and the winding core 200 to rise synchronously by a certain distance through the clamp head 202. Specifically, the first cam 303 is arranged outside the second cam 4, and the third section 4011 is directly opposite the first section 30311. When the second turntable 21 rotates, the first guide wheel 304 and the second guide wheel 306 simultaneously roll from the lowest position to the highest position on their respective guide surfaces, causing the upper ejector 302 and the clamp head 202 to rise synchronously to a certain height. After the clamp head 202 stops rising (at this time, the cup 300 stops rising), the upper ejector 302 continues to rise, causing the winding core 200 to be pushed out of the cup 300 and into the interior of the steel shell 100. The setting of the second cam 4 and the second guide wheel 306 can drive the support cup 300 to rise to a certain height along with the winding core 200 through the clamp head 202. When the support cup 300 rises, the side wall of the support cup 300 is used to provide protection for the rising winding core 200 to prevent the support cup 300 from falling from the upper head 302.

[0046] Specifically, a second stopper 9 is disposed above the second cam 4. A second stopper surface parallel to the second guide surface 401 is disposed on the top surface of the second stopper 9. The upper side of the second cam 4 abuts the second stopper surface, while the lower side of the second cam 4 abuts the second guide surface 401. This mitigates the rolling jolting of the second guide wheel 306 and ensures smooth lifting of the lifting clamp. The second cam 4 and the second stopper 9 are fixed together by a fixing member 11, thereby integrally connecting the two.

[0047] Reference Figure 1 and Figure 7The battery core insertion device further includes a guide sleeve 8 fixed in the through hole. The guide sleeve 8 is provided with a guide hole, which includes a first hole 801 and a second hole 802 connected to the first hole 801. The radial cross-section of the second hole 802 is larger than the radial cross-section of the first hole 801. The first hole 801 is close to the steel shell clamp 1 component, and the second hole 802 is close to the upper top component 3. A limiting step 803 is formed between the first hole 801 and the second hole 802. The limiting step 803 is for the open end of the steel shell 100 to abut, so that the open end of the steel shell 100 can be inserted into the first hole 801. The guide sleeve 8 of this structure ensures that the core 200 will not collide with the edge of the steel shell 100 when moving upward to enter the steel shell 100, thereby avoiding damage to the core 200 and ensuring the production quality of the battery. The guide sleeve 8 also guides the core 200 into the steel shell 100, which is conducive to accelerating the speed at which the core 200 enters the steel shell 100 and improving the efficiency of the core 200 entering the shell. Before the winding core 200 is inserted into the steel shell 100, the receiving slot, guide hole, and core placement area of ​​the steel shell 100 on the main body 101 are connected. To insert the winding core 200, the steel shell 100 on the main body 101 is pushed toward the guide sleeve 8, causing the open end of the steel shell 100 to abut against the stopper 803 in the guide hole. The winding core 200 then enters the steel shell 100 through the second hole 802 and the first hole 801.

[0048] Reference Figures 8 to 10 The steel shell fixture 1 also includes a fixing block 104, through which the main body 101 is fixed to the first turntable 20. One end of the baffle 103 is rotatably connected to the main body 101 via a first rotating shaft 105, and the other end of the baffle 103 is connected to the fixing block 104 via an elastic member 106. The elastic member 106 always has a tendency to drive the baffle 103 to rotate toward the steel shell placement position 102. The main body 101 is provided with a magnet 1011 for attracting the steel shell 100. In this example, the magnet 1011 is fixed inside the main body 101. In a specific implementation, the open end of the steel shell 100 is protruded downward from the baffle 103, and the steel shell 100 is attracted by the magnet 1011 on the body 101. At the same time, the outer wall of the steel shell 100 presses the baffle 103 toward the fixed block 104. The squeezing force of the steel shell 100 overcomes the driving force of the elastic member 106 on the baffle 103, so that the baffle 103 does not protrude from the steel shell placement position 102 (even if the baffle 103 is switched from the first position to the second position). At this time, the winding core 200 can be removed from the steel shell. The open end of the shell 100 enters the steel shell 100. When the winding core 200 enters the steel shell 100, the upper head 302 is used to push the winding core 200 toward the top, so that the steel shell 100 and the winding core 200 move upward together on the main body 101 for a certain distance. Then, the steel shell 100 moves to above the baffle 103, releasing the squeezing of the baffle 103. The elastic member 106 acts to make the baffle 103 move in the direction away from the fixed block 104, so that the baffle 103 is blocked at the open end of the steel shell 100.

[0049] Reference Figure 1 and Figure 2 In order to facilitate the insertion of the steel shell 100 on the main body 101 into the guide sleeve 8, the battery core shell insertion device also includes a steel shell pressing assembly 6 arranged above the steel shell clamp 1, and the steel shell pressing assembly 6 rotates synchronously with the first turntable 20. The steel shell pressing assembly 6 includes a pressing head 601 and a second driving member 602 connected to the pressing head 601. The pressing head 601 pushes the steel shell 100 downward, and the second driving member 602 is used to drive the pressing head 601 to move in the vertical direction. The pressing head 601 is driven by the second driving member 602 to rise and fall. When the pressing head 601 descends, it pushes the steel shell 100 of the main body 101 downward, so that the steel shell 100 is inserted into the first hole 801 from top to bottom and the open end of the steel shell 100 abuts against the limiting step 803.

[0050] Specifically, the steel shell pressing assembly 6 further includes a third cam 5 and a third guide wheel 605. The third cam 5 is fixed above the first rotating disk 20 and is coaxial with the first rotating disk 20. The third guide wheel 605 is disposed at the upper end of the second driving member 602. The third cam 5 is provided with a third guide surface 501 around its circumference, on which the third guide wheel 605 rolls. The third guide surface 501 is provided with a fifth section 5011 and a sixth section 5012. The fifth section 5011 is located at the highest position of the third guide surface 501, and the sixth section 5012 is located at the lowest position of the third guide surface 501. The fifth section 5011 and the sixth section 5012 are sequentially distributed along the rotation direction of the first rotating disk 20. When the third guide wheel 605 rolls from the fifth section 5011 to the sixth section 5012, the second driving member 602 pushes the steel shell 100 downward via the pressing head 601. The third guide surface 501 is an annular structure. As the first turntable 20 rotates, the third guide wheel 605 rolls back and forth along the extension direction of the third guide surface 501. When the third guide wheel 605 rolls from the fifth section 5011 to the sixth section 5012, the second lifting rod 6022 drives the pressing head 601 downward under the action of the third guide wheel 605, thereby automatically squeezing the steel shell 100 downward. The height difference between the fifth section 5011 and the sixth section 5012 is equal to the distance between the open end of the steel shell 100 on the main body 101 and the limiting step 803. In this example, the distance between the open end of the steel shell 100 on the main body 101 and the limiting step 803 is 4 mm.

[0051] Furthermore, a third limiting member 10 is provided above the third guide surface 501, and a third limiting surface parallel to the third guide surface 501 is provided at the bottom of the third limiting member 10. The third limiting surface is spaced from the third guide surface 501, and the upper side of the third guide wheel 605 abuts against the third limiting surface, and the lower side of the third guide wheel 605 abuts against the third guide surface 501 to reduce the bumps when the third guide wheel 605 slides.

[0052] In this example, the third cam 5 and the third limiting member 10 are fixed by a fixing member 11 so as to be connected as one body.

[0053] Reference Figure 2 In order to monitor the thrust of the upper head 302 on the winding core 200, the winding core lifting mechanism also includes a pressure detection component, which includes a first pressure sensor 17, a second pressure sensor 18 and a third pressure sensor 19, which are all fixedly arranged on one side of the first driving member 301. Along the rotation direction of the first turntable 20, the first pressure sensor 17, the second pressure sensor 18 and the third pressure sensor 19 are distributed in sequence. When the first turntable 20 rotates, the first driving member 301 passes through the first pressure sensor 17, the second pressure sensor 18 and the third pressure sensor 19 in sequence. The first driving member 301 and the pressure sensor at the corresponding position make the pressure sensor detect the pressure applied by the second lifting rod 6022 to the upper head 302, thereby obtaining the pressure exerted on the winding core 200 inside the steel shell 100. Specifically, the first pressure sensor 17 is used to detect the thrust exerted on the winding core 200 when it just enters the steel shell 100, the second pressure sensor 18 is used to detect the thrust exerted on the winding core 200 when it enters the 1 / 2 position of the steel shell 100, and the third pressure sensor 19 is used to detect the thrust exerted on the winding core 200 when it completely enters the interior of the steel shell 100.

[0054] Specifically, the steel shell pressing assembly 6 further includes a third rotary disk 606 disposed above the first rotary disk 20. The third rotary disk 606 is coaxial with the first rotary disk 20 and rotates synchronously with the first rotary disk 20. In the vertical direction, the third cam 5, the third rotary disk 606, and the first rotary disk 20 are arranged in sequence from top to bottom. The second driving member 602 includes a second push rod 6021 and a lifting rod 6022 disposed above the second push rod 6021. The second push rod 6021 is connected to the lifting rod 6022 via a third connecting block 6023. The pressing head 601 is disposed at the end of the second push rod 6021 away from the third connecting block 6023. The third guide wheel 605 is disposed at the end of the lifting rod 6022 away from the third connecting block 6023. The end of the lifting rod 6022 away from the third connecting block 6023 extends through the third rotating disk 606. The lifting rod 6022 is movably connected to the third rotating disk 606 via a connecting sleeve 607, allowing the lifting rod 6022 to be raised and lowered relative to the third rotating disk 606. In this example, there are two lifting rods 6022. The upper ends of the two lifting rods 6022 are connected by a fourth connecting block 6024, and the lower ends of the two lifting rods 6022 are connected by a third connecting block 6023. The third guide wheel 605 is mounted on the fourth connecting block 6024.

[0055] In this embodiment, refer to Figure 1The battery core shelling device further includes a driving mechanism 7, which includes a driving motor 701, a rotating shaft 702, and a transmission member. The rotating shaft 702 is vertically arranged. The driving motor 701 drives the rotating shaft 702 to rotate through the transmission member. The first rotating disk 20, the second rotating disk 21, and the third rotating disk 606 are respectively sleeved on the outer periphery of the rotating shaft 702. The rotation of the rotating shaft 702 drives the first rotating disk 20, the second rotating disk 21, and the third rotating disk 606 to rotate synchronously. The transmission member includes a driving gear 703 and a driven gear 704 meshing with the driving gear 703. The driving gear 703 is fixed to the output shaft of the driving motor 701, and the driven gear 704 is fixed to the rotating shaft 702.

[0056] In this example, the first cam 303 is sleeved on the outer circumference of the second cam 4, the second cam 4 is connected to the first cam 303 through a connecting plate, the first cam 303 is connected to the rotating shaft 702 through the mounting seat 23, the rotating shaft 702 can rotate relative to the mounting seat 23, and the mounting seat 23 provides support and fixing for the first cam 303 and the second cam 4.

[0057] In actual implementation, the battery core shell insertion device is used in conjunction with a cup input mechanism and a cup output mechanism. The battery core shell insertion device is provided with a cup input position and a cup output position. The cup input mechanism transfers a cup 300 loaded with a core 200 from the cup input position to the core clamp 2, while the cup output mechanism transfers an empty cup 300 from the cup output position out of the core clamp 2. A fixed first guide plate 12 is provided on one side of the core clamp 2. The first guide plate 12 is located on one side of the core clamp 2, and one end of the first guide plate 12 extends from the cup input position to the cup input position along the rotation direction of the core clamp 2. A second guide plate 13 is provided near the cup input position, forming a cup entry channel between the second guide plate 13 and the first guide plate 12. A third guide plate 14 is provided near the cup output position, forming a cup exit channel between the third guide plate 14 and the first guide plate 12.

[0058] The battery core-shelling device works in conjunction with the steel shell delivery mechanism to automatically deliver the shelled core 200. One side of the battery core-shelling device features a steel shell delivery position, where the steel shell delivery mechanism is located. A fourth guide plate 15 and a fifth guide plate 16 are located at the steel shell delivery position, with a steel shell delivery channel formed between the fourth and fifth guide plates 15, 16. When the first turntable 20 rotates the shelled core 200 to one side of the steel shell delivery position, the steel shell 100 and core 200 on the body 101 are guided into the steel shell delivery mechanism via the steel shell delivery channel, enabling the automatic delivery of the shelled core 200.
