Compared with the existing manual visual inspection method, it has the characteristics of faster response speed, more stability, more reliability and greater safety.

[0028] In order to push the first extrusion plate 4 , the first driving mechanism includes: a first driving member 2 ; the first driving member 2 is electrically connected to the upper machine, and the output portion of the first driving member 2 is connected to the first extrusion plate 4 .

[0029] Specifically, the host computer sends a control signal to the first driving member 2 to drive the first driving member 2 to drive the first extrusion plate 4 to move toward or away from the second extrusion plate 12 , and the battery cell is placed between the first extrusion plate 4 and the second extrusion plate 12 .

[0030] Specifically, the first driving member 2 may be a cylinder, and the first driving member 2 is connected to the first extrusion plate 4 via the cylinder shaft 3 .

[0031] In order to collect the force data of the first extrusion plate 4 in real time, the pressure sensing module includes: a pressure sensor 5 ; the pressure sensor 5 is electrically connected to the upper machine, and the pressure sensor 5 is installed in the first extrusion plate 4 .

[0032] Specifically, the pressure sensor 5 can be used to understand in real time the squeezing condition of the battery cell between the first squeezing plate 4 and the second squeezing plate 12 , thereby ensuring that the squeezing of the battery cell is performed in a safe and stable manner.

[0033] Specifically, a first driving member 2 is arranged on the lower left side of the main frame 1, the first driving member 2 fixes the first extrusion plate 4 through the cylinder shaft 3, and a pressure sensor 5 is installed in the first extrusion plate 4, and the pressure sensor 5 is electrically connected to the host computer.

[0034] In order to push the second extrusion plate 12, the second driving mechanism includes: a second driving member 13, a transmission belt 14 and a screw rod 8; the transmission belt 14 is suitable for connecting the output part of the second driving member 13 with one end of the screw rod 8, and the second extrusion plate 12 is installed on the screw rod 8.

[0035] Specifically, the second driving member 13 may be a servo motor.

[0036] Specifically, the second driving member 13 is installed on the upper right side of the main frame 1, the output shaft of the second driving member 13 is connected to the transmission belt 14, and a screw rod 8 is arranged below the transmission belt 14, the screw rod 8 is connected to the transmission belt 14, and the second extrusion plate 12 is installed on the screw rod 8 by moving the nut.

[0037] Specifically, the second driving member 13 drives the transmission belt 14 to rotate, which in turn drives the screw rod 8 to rotate, so that the second extrusion plate 12 can move horizontally along the length direction of the screw rod 8 .

[0038] In order to prevent the second extrusion plate 12 from excessively moving, a fixing plate 7 is provided at the other end of the screw rod 8 .

[0039] In order to ensure the stability of the movement of the first extrusion plate 4 and the second extrusion plate 12, the extrusion protection device also includes: at least one guide rail 6; the guide rail 6 is installed at the bottom of the main frame 1; the top of the first extrusion plate 4 is slidably connected to the guide rail 6, and the top of the second extrusion plate 12 is slidably connected to the guide rail 6.

[0040] In order to sense the position of the second extrusion plate 12 , the photoelectric sensing module includes: two photoelectric opposing sensors 10 ; the two photoelectric opposing sensors 10 are respectively installed on both sides of the travel path of the second extrusion plate 12 .

At the same time, the second driving member 13 performs a positive rotation action after being controlled by the host computer. The positive rotation action is transmitted to the second extrusion plate 12 through the screw rod 8, and then the second extrusion plate 12 passes through the guide rail 6 and is squeezed inward to perform an extrusion action. When the pressure sensor 5 is pressurized, it will output a certain pressure value and transmit it to the host computer. When the second extrusion plate 12 moves inward, it drives the shielding plate to move. When it moves to the photoelectric radiation sensor 10, it will shield the photoelectric radiation sensor 10 and transmit the shielding signal to the host computer. The host computer receives the pressure value sent by the pressure sensor 5. When the pressure value reaches the protection value valve (the host computer can be adjusted according to the process), it should receive the shielding signal sent by the photoelectric radiation sensor 10 to the host computer. If the shielding signal sent by the photoelectric radiation sensor 10 to the host computer is not received, the host computer will send a protection signal. When the host computer sends the protection signal, it will retract the first driving member 2, and the first driving member 2 is transmitted to the first extrusion plate 4 to move outward. At the same time, when the host computer sends the protection signal, the second driving member 13 performs a reverse motion after being controlled by the host computer, and the reverse motion is transmitted to the second extrusion plate 12 through the screw rod 8 to move outward.
