DETAILED DESCRIPTION

[0024] The first embodiment of the present application is:

[0025] Please refer to Figures 1-3 , wherein, Figure 1 is a structural schematic view of the whole of the first embodiment of the present application, Figure 2 is a front view cross-sectional view of the whole of the first embodiment of the present application, Figure 3 is Figure 2The battery discharging device of the present application comprises a support 101, a cylinder 102, a punching needle 103 and a fixing assembly 104; the fixing assembly 104 comprises a pushing piece 105, a transmission member 106 and a plurality of fixing members 107; the fixing member 107 comprises two fixing parts 108, the fixing part 108 comprises a support 109, an extension body 110, a vertical column 111, a placing plate 112 and a stopper 117; the vertical column 111 has an inclined surface 113; the transmission member 106 comprises a support frame 114, two roller wheels 115 and a conveying belt 116; the extension body 110 comprises a hollow column 118, a first spring 119 and a sliding rod 120.

[0026] For the specific embodiment, the cylinder 102 is fixedly connected with the support 101 and located at one side of the support 101, and the punching needle 103 is fixedly connected with an output rod of the cylinder 102 and located at one side of the cylinder 102. The support 101 is used for supporting the cylinder 102, and the cylinder 102 drives the punching needle 103 to move longitudinally to punch and discharge a lithium battery.

[0027] The pushing piece 105 is fixedly connected with the output rod of the air cylinder 102 and located at the side of the output rod of the air cylinder 102; the transmission member 106 is located at the side of the support 101; a plurality of the fixing members 107 are respectively located at the sides of the transmission member 106; two fixing portions 108 are respectively located at the sides of the transmission member 106; the strut 109 is fixedly connected with the transmission member 106 and located at one side of the transmission member 106; the telescopic body 110 is fixedly connected with the strut 109 and located at the side of the strut 109; the stand 111 is fixedly connected with the telescopic body 110 and located at one side of the telescopic body 110; the placing plate 112 is fixedly connected with the stand 111 and located at one side of the stand 111. The telescopic body 110 is elastic and can horizontally expand and contract. The lithium battery is placed on the two placing plates 112 of the fixing member 107. At this time, the two stands 111 do not contact the side of the lithium battery. After the transmission member 106 transports the fixing member 107 to the position below the punching needle 103, the transmission member 106 stops transporting the fixing member 107. Then, the air cylinder 102 drives the pushing piece 105 and the punching needle 103 to move downward. The pushing piece 105 first contacts the inclined surface 113 on the two stands 111. After the inclined surface 113 is stressed, the two stands 111 move close to each other, stretching the telescopic body 110. At this time, the two stands 111 clamp and fix the lithium battery (the two placing plates 112 do not contact each other, so that the punching needle 103 can pass through when punching). Then, the punching needle 103 moves downward to contact the lithium battery to punch holes. In this way, the lithium battery can be fixed when the lithium battery is punched, avoiding movement of the lithium battery when the lithium battery is punched.

[0028] Secondly, the support frame 114 is located at one side of the support 101; two roller wheels 115 are rotationally connected with the support frame 114 and respectively located at the sides of the support frame 114; and the conveying belt 116 is rotationally connected with the two roller wheels 115 and located at the sides of the two roller wheels 115. The support frame 114 is used for supporting the two roller wheels 115. An external rotary driving device is used to drive the two roller wheels 115 to rotate, so that the conveying belt 116 flows to transport the lithium battery.

[0029] Meanwhile, the stopper 117 is fixedly connected with the column 111 and located at one side of the column 111. The stopper 117 is shorter than the placing plate 112. When the column 111 approaches the lithium battery, the column 111 drives the stopper 117 to approach the lithium battery. At this time, the stopper 117 is above the lithium battery and limits the lithium battery. When the punching needle 103 is pulled out of the lithium battery, the stopper 117 will leave the lithium battery after the punching needle 103 is pulled out of the lithium battery. The stopper 117 can avoid the lithium battery from moving with the punching needle 103 when the punching needle 103 is pulled out.

[0030] In addition, the hollow column 118 is fixedly connected with the support 109 and located at one side of the support 109.

The sliding rod 120 is fixedly connected with the first spring 119 and the column 111 and located between the first spring 119 and the column 111. The hollow column 118 is used for providing a guide for the first spring 119. The sliding rod 120 is used for connecting the first spring 119 and the column 111. The elastic potential energy of the first spring 119 can drive the column 111 to reset when the column 111 approaches the lithium battery.

[0031] The battery discharging device of the embodiment, the support frame 114 is used for supporting two roller wheels 115, two roller wheels 115 are driven to rotate by an external rotating driving device, so that the conveying belt 116 flows to transport lithium batteries; the lithium batteries are placed on two placing plates 112 of the fixing member 107, at this time, two stand columns 111 do not contact the side edges of the lithium batteries, after the transmission member 106 transports the fixing member 107 to below the punching needle 103, the transmission member 106 stops transporting the fixing member 107, then the air cylinder 102 drives the pushing piece 105 and the punching needle 103 to move downward, the pushing piece 105 first contacts the inclined surface 113 on two stand columns 111, after the inclined surface 113 is stressed, two stand columns 111 are close to each other, the first spring 119 is stretched, at this time, two stand columns 111 clamp and fix the lithium batteries, at the same time, the stand column 111 drives the stop block 117 to be close to the lithium batteries, so that the stop block 117 is above the lithium batteries and limits the lithium batteries, then the punching needle 103 moves downward and contacts the lithium batteries to punch holes, so that the lithium batteries are prevented from moving when the holes are punched, after the punching is completed, the air cylinder 102 drives the pushing piece 105 and the punching needle 103 to move upward and away from the lithium batteries, the first spring 119 is retracted to drive the stand column 111 and the stop block 117 to be away from the lithium batteries, so that the lithium batteries are fixed, after the punching needle 103 is pulled out of the lithium batteries, the stop block 117 is away from the lithium batteries, the stop block 117 can prevent the lithium batteries from moving with the punching needle 103 when the punching needle 103 is pulled out, then the conveying belt 116 transports the fixing member 107 and the lithium batteries to be away from below the punching needle 103, so as to punch holes and discharge another lithium battery; in the above manner, the lithium batteries are fixed when the holes are punched, so that the lithium batteries are prevented from moving when the holes are punched.
