A voltage detection machine is a device that can detect the voltage of lithium batteries. When in use, the two detection heads of the machine body are placed on the positive and negative electrodes of the lithium battery. Due to the shape of the cylindrical lithium battery, it is easy to roll back and forth during detection. The detector needs to hold the detection heads with both hands and cannot stabilize the position of the lithium battery, which affects the detection efficiency and accuracy. However, the voltage detection machines used in the existing lithium battery production do not have components for more stable detection of lithium batteries. Therefore, a voltage detection device for lithium battery production is specifically proposed to solve the above problems. Content of the Utility Model

[0003] Aiming at the problems existing in the prior art, the utility model provides a voltage detection device for lithium battery production, which has the advantage of enabling the voltage detection machine used in lithium battery production to detect lithium batteries more stably, and solves the problems that in order to ensure the charging capacity, health status, and safety of lithium batteries, voltage detection of lithium batteries is required during the production process. A voltage detection machine is a device that can detect the voltage of lithium batteries. When in use, the two detection heads of the machine body are placed on the positive and negative electrodes of the lithium battery. Due to the shape of the cylindrical lithium battery, it is easy to roll back and forth during detection. The detector needs to hold the detection heads with both hands and cannot stabilize the position of the lithium battery, which affects the detection efficiency and accuracy. However, the voltage detection machines used in the existing lithium battery production do not have components for more stable detection of lithium batteries.

[0004] The utility model is realized as follows: A voltage detection device for lithium battery production includes a voltage detection machine and two limit bases. The rear side of the voltage detection machine is fixedly connected to the front side of the limit base. The top of the limit base is movably connected with a limit top ring. The bottom of the limit top ring is fixedly connected with a device shell. Both the left and right sides of the device shell are in contact with the surface of the limit base. A lithium battery is placed on the opposite sides of the limit base and the limit top ring. A fixing device is arranged in the inner cavity of the device shell.

[0005] Preferably, the fixing device of the utility model comprises two fixing clamping columns. The opposite sides of the two fixing clamping columns penetrate through the device shell and extend to the outside of the inner cavity of the device shell. Two moving shells are fixedly connected to the opposite sides of the two fixing clamping columns. The bottom of the inner cavity of the device shell is fixedly connected with two moving clamping frames which are used in cooperation with the moving shells. The surface of the moving clamping frame is movably connected with the inner cavity of the moving shell. Springs are fixedly connected to the opposite sides of the two fixing clamping columns. The opposite sides of the two springs are fixedly connected with the surface of the moving clamping frame. By arranging the fixing device, when the bottom of the limiting top ring contacts the top of the limiting base, the fixing device has a limiting effect on the position of the limiting top ring.

[0006] Preferably, two extrusion square frames are arranged in the inner cavity of the device shell. The opposite sides of the two extrusion square frames are fixedly connected with the surface of the moving shell. By arranging the extrusion square frames, when the extrusion square frames move, they can drive the moving shells to move along the surface of the moving clamping frames.

[0007] Preferably, the bottom of the inner cavity of the device shell is movably connected with an extrusion control rod which is used in cooperation with the extrusion square frames through a rotating shaft. The surface of the extrusion control rod contacts the inner cavity of the extrusion square frame. By arranging the extrusion control rod, rotating the extrusion control rod drives the extrusion control rod to rotate along the inner cavity of the extrusion square frame.

[0008] Preferably, a clamping column groove which is used in cooperation with the fixing clamping columns is formed on the surface of the limiting base. The surface of the fixing clamping column contacts the inner cavity of the clamping column groove. By arranging the clamping column groove, when the device shell moves to a position where it contacts the surface of the limiting base and the extrusion control rod is released, the restoring force generated by the spring restoring its shape will drive the fixing clamping column to be clamped into the inner cavity of the clamping column groove. The cooperation of the fixing clamping column and the clamping column groove has a limiting effect on the position of the device shell.

[0009] Preferably, adjusting sliding plates are fixedly connected to the left and right sides of the limiting top ring. Adjusting sliding grooves which are used in cooperation with the adjusting sliding plates are formed on the surface of the limiting base. The surface of the adjusting sliding plate is movably connected with the inner cavity of the adjusting sliding groove. By arranging the adjusting sliding plates and the adjusting sliding grooves, when the device shell moves, it will drive the adjusting sliding plates to move along the inner cavity of the adjusting sliding grooves. The cooperation of the adjusting sliding plates and the adjusting sliding grooves has a limiting effect on the moving position of the device shell.

[0010] Preferably, anti-slip pads are fixedly connected to the top of the limit base and the bottom of the limit top ring. The anti-slip pads are made of rubber, and the surface of the anti-slip pads is in close contact with the surface of the lithium battery. By setting the anti-slip pads, the anti-slip pads increase the friction between the limit base and the limit top ring and the lithium battery, making the limit of the lithium battery by the limit base and the limit top ring more stable.

[0011] 1. By using the cooperation of the fixing device, the fixed clamping column, the moving shell, the moving clamping frame and the clamping column groove, the present utility model solves the problem that in order to ensure the charging capacity, health status and safety of lithium batteries, voltage detection needs to be carried out on lithium batteries during the production process. A voltage detection machine is a device that can detect the voltage of lithium batteries. When in use, the two detection heads of the machine body are placed on the positive and negative electrodes of the lithium battery. Due to the shape of the cylindrical lithium battery, it is easy to roll back and forth during detection. The detector needs to hold the detection heads with both hands and cannot stabilize the position of the lithium battery, affecting the detection efficiency and accuracy. However, the existing voltage detection machines used in lithium battery production do not have components for more stable detection of lithium batteries.

[0012] 2. By setting the fixing device in the present utility model, when the extrusion square frame moves, it will drive the two moving shells to move along the surface of the moving clamping frame. When the moving shells move, they will drive the two fixed clamping columns to move towards each other. When the fixed clamping columns move, the force generated will cause the spring to undergo elastic deformation.

[0019] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0020] As Figures 1 to 4 shown, a voltage detection device for lithium battery production provided by an embodiment of the present utility model includes a voltage detector 1 and two limit bases 2. The rear side of the voltage detector 1 is fixedly connected to the front side of the limit base 2. A limit top ring 3 is movably connected to the top of the limit base 2. The bottom of the limit top ring 3 is fixedly connected to a device shell 4. The left and right sides of the device shell 4 are in contact with the surface of the limit base 2. A lithium battery 5 is placed on the opposite sides of the limit base 2 and the limit top ring 3. A fixing device 6 is arranged in the inner cavity of the device shell 4.

[0021] Referring to Figure 4 , the fixing device 6 includes two fixing columns 601. The opposite sides of the two fixing columns 601 penetrate through the device shell 4 and extend to the outside of the inner cavity of the device shell 4. Two moving shells 602 are fixedly connected to the opposite sides of the two fixing columns 601. Two moving card frames 603 which are matched with the moving shells 602 are fixedly connected to the bottom of the inner cavity of the device shell 4. The surface of the moving card frame 603 is movably connected to the inner cavity of the moving shell 602. Two springs 604 are fixedly connected to the opposite sides of the two fixing columns 601. The opposite sides of the two springs 604 are fixedly connected to the surface of the moving card frame 603.

[0022] Adopting the above scheme: By setting the fixing device 6, when the bottom of the limit top ring 3 contacts the top of the limit base 2, the fixing device 6 has a limiting effect on the position of the limit top ring 3.

[0023] Referring to Figure 4 , two extrusion boxes 7 are arranged in the inner cavity of the device shell 4. The opposite sides of the two extrusion boxes 7 are fixedly connected to the surface of the moving shell 602.

[0024] Adopting the above scheme: By setting the extrusion box 7, when the extrusion box 7 moves, it can drive the moving shell 602 to move along the surface of the moving card frame 603.

[0025] Referring to Figure 4 , the bottom of the inner cavity of the device shell 4 is movably connected by a rotating shaft with an extrusion control rod 8 which is matched with the extrusion box 7. The surface of the extrusion control rod 8 is in contact with the inner cavity of the extrusion box 7.

[0026] Adopt the above scheme: By setting the extrusion control rod 8, rotating the extrusion control rod 8 drives the extrusion control rod 8 to rotate along the inner cavity of the extrusion square box 7, and the extrusion force of the extrusion control rod 8 on the extrusion square box 7 can drive the two extrusion square boxes 7 to move.

[0027] Reference Figure 3 , a column groove 9 for cooperating with the fixed clamping column 601 is provided on the surface of the limit base 2, and the surface of the fixed clamping column 601 is in contact with the inner cavity of the column groove 9.

[0028] Adopt the above scheme: By setting the column groove 9, when the device shell 4 moves to a position in contact with the surface of the limit base 2 and the extrusion control rod 8 is released, the restoring force generated by the spring 604 restoring its shape will drive the fixed clamping column 601 to snap into the inner cavity of the column groove 9, and the cooperation of the fixed clamping column 601 and the column groove 9 has a limiting effect on the position of the device shell 4.

[0029] Reference Figure 3 , adjusting slides 10 are fixedly connected to both the left and right sides of the limit top ring 3, an adjusting chute 11 for cooperating with the adjusting slide 10 is provided on the surface of the limit base 2, and the surface of the adjusting slide 10 is movably connected to the inner cavity of the adjusting chute 11.

[0030] Adopt the above scheme: By setting the adjusting slide 10 and the adjusting chute 11, when the device shell 4 moves, it will drive the adjusting slide 10 to move along the inner cavity of the adjusting chute 11, and the cooperation of the adjusting slide 10 and the adjusting chute 11 has a limiting effect on the moving position of the device shell 4.

[0031] Reference Figure 3 , anti-slip pads 12 are fixedly connected to both the top of the limit base 2 and the bottom of the limit top ring 3. The anti-slip pads 12 are made of rubber, and the surface of the anti-slip pads 12 is in close contact with the surface of the lithium battery 5.

[0032] Adopt the above scheme: By setting the anti-slip pads 12, the setting of the anti-slip pads 12 increases the friction between the limit base 2 and the limit top ring 3 and the lithium battery 5, making the limit of the lithium battery 5 by the limit base 2 and the limit top ring 3 more stable.

[0033] During use, when the voltage detector 1 used in the production of lithium battery 5 needs to perform more stable detection on lithium battery 5, first the user places lithium battery 5 in the inner cavity of the limit base 2, and then rotates the extrusion control rod 8. When the extrusion control rod 8 rotates, it will generate an extrusion force on the extrusion square frame 7. The two extrusion square frames 7 subjected to the extrusion force will move towards the side close to each other. When the extrusion square frame 7 moves, it will drive the two moving shells 602 to move along the surface of the moving card frame 603. When the moving shell 602 moves, it will drive the two fixed clamping columns 601 to move towards the side close to each other. When the fixed clamping column 601 moves, the force generated causes the spring 604 to undergo elastic deformation. When the fixed clamping column 601 completely moves into the inner cavity of the device shell 4, move the limit top ring 3 towards the side close to lithium battery 5, drive the device shell 4 to move at the same time, and drive the adjustment slide plate 10 to move towards the bottom along the inner cavity of the adjustment chute 11. When the anti-slip pads 12 on the surfaces of the limit base 2 and the limit top ring 3 are both in close contact with the surface of lithium battery 5, release the extrusion control rod 8. The restoring force generated when the spring 604 restores its shape will drive the fixed clamping column 601 to snap into the inner cavity of the clamping column groove 9. The combined use of the fixed clamping column 601 and the clamping column groove 9 has a limiting effect on the positions of the device and the limit top ring 3. The combined use of the limit top ring 3 and the limit base 2 has a limiting effect on the position of lithium battery 5. When the position of lithium battery 5 is limited, stable detection of lithium battery 5 can be carried out. At this time, the voltage detector 1 used in the production of lithium battery 5 completes more stable detection of lithium battery 5.

[0034] To sum up: For this voltage detection device used in lithium battery production, through the combined use of the fixing device 6, the fixed clamping column 601, the moving shell 602, the moving card frame 603 and the clamping column groove 9, it solves the problem that in order to ensure the charging ability, health status and safety of lithium batteries, voltage detection of lithium batteries is required during the production process. A voltage detector is a device that can detect the voltage of lithium batteries. During use, the two detection heads of the machine body are placed on the positive and negative electrodes of the lithium battery. Due to the shape of the cylindrical lithium battery, it is easy to roll back and forth during detection. The detector needs to hold the detection heads with both hands and cannot stabilize the position of the lithium battery, affecting the detection efficiency and accuracy. However, the existing voltage detectors used in lithium battery production do not have components for more stable detection of lithium batteries.
