[0045] The working principle of the utility model is as follows:

[0046] The jaw cylinder 1 is fixedly installed on the mounting frame 6, and a pressure sensing element 5 is arranged on the two lower ends of the jaw cylinder 1, that is, the clamping ends; the pressure sensing element 5 is a pressure sensor; the jaw single arm 2 is connected with the detection end of the pressure sensing element 5 through a connecting unit; the first horizontal guide rail 14 is arranged on the mounting frame 6; the first horizontal sliding block is fixedly connected to the corresponding mounting plate 3 of each jaw single arm 2; the first horizontal sliding block is slidably connected with the first horizontal guide rail 14; the jaw cylinder 1 can drive the jaw single arm 2 to move linearly on the first horizontal guide rail 14; the photoelectric switch is arranged on the mounting clamp; the photoelectric switch can detect the position of the jaw single arm 2; the battery cell sensing element 11 is arranged on the jaw single arm 2 and can detect whether the battery cell 16 is clamped between the two jaw single arms 2; the battery cell sensing element 11 can be a reflection sensor; when the battery cell 16 is in place, the reflection sensor can sense the battery cell 16; at this time, the jaw cylinder 1 starts to close and tightly grips the two sides of the battery cell 16; at the same time, the pressure sensing element is subjected to an interaction force of the battery cell 16 on the jaw single arm 2; when the clamping force reaches the set value, the jaw cylinder 1 will execute the next action. Based on this, the device can detect the actual clamping force requirement while grasping the battery cell 16.

[0047] Compared with the common battery cell 16 clamping mechanism, the battery cell 16 clamping device for detecting the grasping force, that is, the clamping force, adopts a bear clamping jaw, so that even if the clamping pressure decreases, the mechanical grasping force maintaining device can also ensure the minimum grasping force. The jaw single arm 2 can input gas through the gas injection nozzle 13, the gas injection nozzle 13 blows the side edge of the grasped battery cell 16 through the air outlet, and the battery cell 16 is cleaned by blowing gas at the same time when the battery cell 16 is clamped, so that the working efficiency is high; the external gas source can blow gas to the battery cell 16 through the air outlet penetrating the jaw single arm 2 close to the side wall of the battery cell 16. In particular, the problem that the battery cell 16 slips due to too small clamping force of the jaw cylinder 1 and the problem that the battery cell 16 is damaged due to too large clamping force of the jaw cylinder 1 can be solved.

[0048] The recess 21 is arranged for clamping the single-arm 2 of the clamp, avoiding the single-arm 2 of the clamp from loosening, at the same time, the upper end of the single-arm 2 of the clamp extends into the clamping groove, the anti-loosing block 4 in L shape presses the bottom of the upper end of the single-arm 2 of the clamp, and the protrusion 31 on the bottom of the mounting plate 3 presses the top of the upper end of the single-arm 2 of the clamp, the midpoint of the protrusion 31 and the midpoint of the anti-loosing block 4 are not on the same vertical line, so that the horizontal two parts of the single-arm 2 of the clamp are subjected to the vertical upward force and the vertical downward force respectively, further, the protrusion 31 cooperates with the recess 21, avoiding the single-arm 2 of the clamp from loosening in the vertical and horizontal directions.

[0049] The detection end of the pressure sensing element extends into the connecting groove 32, which can provide enough space for the detection end of the pressure sensing element, at the same time, avoiding other components from interfering with the detection end of the pressure sensing element in the moving process, avoiding affecting the detection precision, in the embodiment, the photoelectric switch can be arranged above the first horizontal track.

[0050] The technical means disclosed by the utility model scheme is not only limited to the technical means disclosed by the above-mentioned embodiment, but also includes the technical scheme composed of any combination of the above technical features.
