[0026] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See also Figures 1-6 In one embodiment of the present invention, a solid-state lithium battery loading device includes a shell component 1, the shell component 1 includes a base 101, a loading port 102, a discharge port 103, a fixing frame 105 and a feeding trough 106. The loading port 102 and the discharge port 103 are fixedly assembled at both ends of the base 101. A damping clamp 104 is also arranged on the inner wall of the loading port 102 and the discharge port 103. A fixing frame 105 is also fixedly arranged in the middle of the base 101. The frame 105 is provided with a feed trough 106; a turntable assembly 2, the turntable assembly 2 includes a rotary disk 201 and a top groove 202, the rotary disk 201 is rotatably assembled on the damping retaining ring 104, and a plurality of top grooves 202 are arranged circumferentially on the rotary disk 201, and the top grooves 202 are all arranged toward the center of the rotary disk 201; a driving mechanism 3, the driving mechanism 3 includes a driver 301, a cam 302, a connecting arm 303, a reciprocating arm 304, a column head 30 6. A first rocker arm 307 and a second rocker arm 309, wherein the driver 301 is fixedly assembled on the base 101, and a cam 302 is rotatably assembled thereon, and a connecting arm 303 is rotatably assembled on the cam 302, and a reciprocating arm 304 is rotatably assembled at the end of the connecting arm 303, and the reciprocating arm 304 is slidably assembled in the fixed frame 105, and the first rocker arm 307 and the second rocker arm 309 are rotatably assembled on both sides of the end thereof, and the end of the first rocker arm 307 is rotatably assembled with a pushing block 308, and the pushing block 308 is slidably arranged in the feeding trough 106, and the end of the second rocker arm 309 is rotatably assembled with a discharging block 310; an electrical detection component 4, wherein the electrical detection component 4 is arranged on the loading port 102 and the pushing block 308, and is used to detect the conductive performance of the solid-state lithium battery; and a transmission component 5, wherein the transmission component 5 is arranged between the turntable component 2 and the driving mechanism 3, and is used to drive the turntable component 2 to rotate in conjunction with the driving mechanism 3.

[0028] In actual application of this embodiment, when the solid-state lithium battery is loaded through the device, the solid-state lithium battery to be loaded is first fed into the feed tube 107 through the external flow channel, and the lithium battery is stacked in the storage channel 108 in a strip shape, and the notch on one side of the storage channel 108 is connected to the feed trough 106, so that the solid-state lithium battery can prevent the remaining lithium batteries in the feed tube 107 from rolling out while rolling into the feed trough 106. At this time, by driving the driver 301 to move, the cam can be driven by the rotation of the driver 301. 302 rotates circumferentially, and the end of the cam 302 is rotatably equipped with a connecting arm 303. When the connecting arm 303 rotates, it can drive the reciprocating arm 304 to slide back and forth in the fixed frame 105. When the reciprocating arm 304 moves toward the side away from the fixed frame 105, the first swing rod 307 and the second swing rod 309 can respectively drive the pushing block 308 and the unloading block 310 to move toward the side close to the reciprocating arm 304, and on the side of the pushing block 308, it can slide to one end of the guide tube 107, so that the lithium battery rolls from it to In the feed trough 106, when the reciprocating arm 304 drives the column head 306 to move toward the side close to the fixed frame 105, the pushing block 308 can press the lithium battery on the feed trough 106 toward the top groove 202 on the turntable 201, and make the lithium battery slide along the feed trough 106 into the top groove 202 on one side. At this time, the electrical status of the lithium battery to be tested can be detected by the electrical detection component 4 arranged between the loading port 102 and the pushing block 308. At the same time, when the unloading block 310 slides toward the side of the unloading port 103, it can be The qualified lithium batteries on the top groove 202 are discharged out of the equipment for subsequent packaging operations, and the turntable assembly 2 and the drive mechanism 3 are linked by the transmission assembly 5, so that the electrical test is carried out on one side of the loading port 102 while the discharge port 103 can be carried out. When the electrical test is completed, the reciprocating arm 304 slides in the opposite direction, so that the lithium batteries remaining on the top groove 202 can rotate with the turntable 201, and are subsequently tested by the appearance inspection assembly 6 on one side, thereby realizing the quality inspection of each group of solid-state lithium batteries while continuously loading.

[0029] In one case of this embodiment, the loading device is limited to loading cylindrical solid-state lithium batteries and is not suitable for loading sheet-shaped or strip-shaped solid-state lithium batteries, which will not be described in detail here.

[0030] See also Figure 4 and Figure 5In a preferred embodiment of the present invention, the shell component 1 further includes a feed pipe 107, a storage channel 108 and a discharge trough 109. The feed pipe 107 is arranged on one side of the feed trough 106, and a storage channel 108 is arranged inside the feed pipe 107. The storage channel 108 is communicated with the feed trough 106. The discharge trough 109 is arranged on one side of the discharge port 103 for subsequent loading and supplying of the battery.

[0031] In actual application of this embodiment, the feed tube 107 is arranged at one end of the fixed frame 105, and the lithium batteries to be tested stacked therein can be introduced into the feed trough 106 through the storage channel 108. During the sliding process of the pushing block 308, when the pushing block 308 retreats to the end of the feed trough 106, the feed tube 107 is in a fully conductive state, which can make the lithium batteries therein roll out into the feed trough 106. When the pushing block 308 is pushed toward the lithium battery, it can be pushed out along the feed trough 106. At the same time, the notch on one side of the storage channel 108 can be closed to prevent the remaining lithium batteries from rolling out, thereby realizing continuous loading of lithium batteries during the reciprocating motion.

[0032] In one case of this embodiment, the unloading chute 109 is arranged at one end of the discharge port 103, which can cooperate with the reciprocating motion of the unloading block 310 to drive the sliding of the lithium battery, and unload the inspected lithium battery from the equipment through the unloading chute 109 for subsequent packaging process.

[0033] See also Figure 2 and Figure 6 In a preferred embodiment of the present invention, the turntable assembly 2 further includes a slot 203, a scroll wheel 204, a transmission belt 205 and a transmission wheel 206. The slot 203 is arranged at the bottom of the top slot 202, and the scroll wheel 204 is rotatably assembled on the turntable 201 and arranged at one end of the slot 203. A transmission belt 205 is also assembled and connected to one side of the scroll wheel 204, and the transmission belt 205 is engaged with the base 101 through the transmission wheel 206.

[0034] In actual application of this embodiment, the transmission belt 205 at one end of the scroll wheel 204 is engaged with the base 101 through the transmission wheel 206, so that the scroll wheel 204 can be driven to rotate during the circumferential movement of the turntable 201, so that the scroll wheel 204 passes through the groove 203 and drives the lithium battery thereon to rotate, thereby performing a comprehensive circumferential inspection of the outer shell of the lithium battery.

[0035] In one case of this embodiment, a gap is set between the turntable 201 and the loading port 102 as well as the unloading port 103. The gap setting between the turntable 201 and the loading port 102 as well as the unloading port 103 can avoid friction during the rotation process, and at the same time can reduce the size of the gap between the turntable 201 and the loading port 102 as well as the unloading port 103 to prevent the lithium battery from getting stuck during the sliding process.

[0036] See also Figure 3 In a preferred embodiment of this embodiment, the driving mechanism 3 further includes a ratchet 305 , and the ratchet 305 is elastically and movably assembled on one side of the reciprocating arm 304 .

[0037] In actual application of this embodiment, the ratchet 305 is elastically limited and rotated and assembled on one side of the reciprocating arm 304, so that when it follows the reciprocating arm 304 to make reciprocating motion in the vertical direction, it can intermittently drive the transmission component 5 on one side thereof to move, so that the turntable 201 only moves synchronously with the unidirectional motion of the reciprocating arm 304, and when the reciprocating arm 304 moves vertically downward, the turntable 201 remains stationary, and when the reciprocating arm 304 moves vertically upward, the turntable 201 rotates synchronously.

[0038] In one case of this embodiment, the turntable 201 rotates by the damping collar by default, and only performs a fixed angle rotation motion following the drive of the reciprocating arm 304 , and the movement caused by inertia is negligible.

[0039] See also Figure 3 In a preferred embodiment of the present invention, the electrical detection component 4 includes an electrical detection module 401, a front electrode sheet 402 and a rear electrode sheet 403. The electrical detection module 401 is fixedly mounted on the fixing frame 105. The two ends of the electrical detection module 401 are respectively connected to the front electrode sheet 402 and the rear electrode sheet 403. The front electrode sheet 402 is fixedly mounted on one side of the pushing block 308. The front electrode sheet 402 is arranged in the loading port 102 and is elastically and movably mounted thereon, and is used to movably resist the solid-state lithium battery to be detected.

[0040] In actual application of this embodiment, the two ends of the electrical detection module 401 are connected to the front electrode sheet 402 and the rear electrode sheet 403. The front electrode sheet 402 is fixedly assembled on one side of the pushing block 308. The front electrode sheet 402 is arranged in the loading port 102 and is elastically assembled thereon, so that when the pushing block 308 drives the lithium battery to press toward the side of the loading port 102, the two electrodes of the lithium battery are respectively pressed between the front electrode sheet 402 and the rear electrode sheet 403, so that its electrical function can be quickly detected, and the detection process and the pushing process are integrated, which not only eliminates the need for a separate detection structure, but also saves the process time required for the conventional detection process.

[0041] See also Figure 2 and Figure 3 In a preferred embodiment of the present invention, the transmission assembly 5 includes a first transmission tooth 501, a second transmission tooth 502, a third transmission tooth 503 and an outer gear ring 504. The first transmission tooth 501 is arranged on one side of the ratchet plate 305 and is meshed with the ratchet plate 305. The second transmission tooth 502 is arranged at one end of the first transmission tooth 501 and is linked to the first transmission tooth 501. The third transmission tooth 503 is rotatably assembled on one end of the fixed frame 105. The outer gear ring 504 is fixedly assembled on the inner wall of the turntable 201. One end of the third transmission tooth 503 is meshed with the second transmission tooth 502, and the other end is meshed with the outer gear ring 504.

[0042] In actual application of this embodiment, since the first transmission tooth 501 is engaged with the ratchet 305, when the ratchet 305 slides in a vertical direction, the first transmission tooth 501 can be driven to rotate unidirectionally, thereby driving the second transmission tooth 502 to rotate synchronously, and the third transmission tooth 503 engaged with the second transmission tooth 502 can engage and drive the outer gear ring 504 on one side thereof to rotate, so that the outer gear ring 504 drives the turntable 201 to rotate unidirectionally on the damping retaining ring 104.

The inner ring frame 602 is arranged on the inner side of the turntable 201, and is provided with a plurality of dischargers 603. The discharger 603 is arranged toward the side of the top groove 202 for ejecting the solid-state lithium batteries that fail the inspection.

[0044] In actual application of this embodiment, the visual inspection module 601 can be connected to a CCD camera to detect the outer shell size and outer surface damage of the lithium battery, and in conjunction with the electrical function detection of the electrical detection component 4, the inner ring frame 602 and the discharger 603 can be used to eject and discharge the unqualified lithium batteries, so that the screened lithium batteries can be discharged through the discharge trough 109.
