The clamping plates are also provided with material inspection holes, and the material inspection holes are equipped with detection sensors 34 to identify the material information between the two sets of clamping plates to determine whether the battery cell 01 is in place. If there is a leakage, the equipment will stop operating, and the abnormality will be identified and adjusted manually.

[0064] In the above structure, the rotating cylinder 31 is installed on the bottom mounting seat 33, for rotating the plurality of battery cells from the vertical state to the horizontal state with the opposite facets, the clamping cylinder 32 is installed on the rotating cylinder 31, for clamping the battery cell, the detection sensor 34 is used for detecting whether the battery cell is on the clamping jaw, to determine whether the current station can act, the specific action includes the following steps: the detection sensor 34 detects whether the battery cell 01 is transferred to the clamping plate of the clamping cylinder 32, and then the clamping cylinder 32 operates to fix the battery cell 01 through the clamping plate, and then the rotating cylinder 31 operates to adjust the battery cell from the vertical state to the horizontal state with the opposite facets, and finally, the pitch changing mechanism operates to make the facets of each battery cell 01 fit together.

[0065] It needs to be explained in detail that the pitch changing mechanism includes a second driving unit 23 arranged in the processing station 2, a shaft coupling 24, a transmission screw rod 25, a screw rod support 26 and a nut seat 27;

[0066] The second driving unit 23 transmits power to the transmission screw rod 25 through the shaft coupling 24 to drive it to rotate;

[0067] The screw rod support 26 is arranged at both ends of the transmission screw rod 25 to bear the transmission screw rod 25;

[0068] The nut seat 27 is sleeved on the transmission screw rod 25 and is in threaded connection with the transmission screw rod 25, the transmission screw rod 25 is provided with two opposite threads, and the nut seat 27 translates with the rotation of the transmission screw rod 25.

[0070] In the above structure, the two groups of the second driving unit 23 are fixedly installed on one side of the conveying bottom plate 21, the output ends of the two groups are provided with the shaft coupling 24, and the shaft coupling 24 is in transmission connection with the corresponding transmission screw rod 25, and the screw rod support 26 is arranged at one end of the transmission screw rod 25 away from the shaft coupling 24 to support the transmission screw rod 25;

[0071] The nut seat 27 is slidably installed on the conveying bottom plate 21, and the nut seat 27 is in threaded connection with the transmission screw rod 25, so that the nut seat 27 is driven to translate through the engagement of the two during the rotation of the transmission screw rod 25.

[0072] As shown in the figure, the clamps 3 are distributed on both sides of the conveying bottom plate 21. Figure 1

[0073] ​In the present application, the mounting seat 33 is provided with a connecting block 36 close to one side of the transmission screw rod 25, and the clamp 3 extends into the cover plate 211 through the connecting block 36 and is fixedly connected with the nut seat 27;

[0074] Specifically, the connecting block 36 is matched with the nut seat 27 arranged on the transmission screw rod 25, so as to drive the corresponding clamp 3 to move along with the second driving unit 23.

[0075] Through the above structure, the rotation speed of the two groups of transmission screw rods 25 or the pitch of the threads thereon is inconsistent, so that in actual operation, the speed difference of the nut seats 27 on the two groups of transmission screw rods 25 is ensured, and the speed difference can make each clamp 3 connected with the nut seat 27 relatively close to or away from the center, thereby realizing the effect of variable pitch.

[0076] Specifically, in an embodiment, when the variable pitch adjustment is performed, the middle two groups of opposite clamps 3 are in transmission connection with one group of transmission screw rods 25, the transmission screw rod 25 has a slower rotation speed or a narrower pitch, and the outer two groups of clamps 3 are in transmission connection with another group of transmission screw rods 25, the transmission screw rod 25 has a faster rotation speed or a wider pitch, so that in the operation process of the two groups of transmission screw rods 25, the effect that the inner and outer clamps 3 have different moving distances or speeds at the same time is realized, so as to control the middle two groups of opposite clamps 3 and the outer two groups of clamps 3 to move synchronously toward the center and be combined into groups.

[0077] In a preferred embodiment, the processing station 2 is provided with at least two clamps 3 corresponding to the variable pitch mechanism and arranged equidistantly along the length direction of the transmission screw rod 25;

[0078] It should be noted that in order to monitor the extrusion force of the multiple battery cells in the combining process in real time, the opposite sides of the clamps 3 at both ends are vertically provided with abutting plates 35 abutting against the opposite sides of the battery cells 01;

[0079] The clamps 3 at both ends are provided with slide rail assemblies 37 and pressure sensors for detecting the extrusion force of the battery cells 01 in the combining process;

[0080] Specifically, the mounting seats 33 of the clamps 3 at both ends are slidingly arranged on the slide rail assemblies 37, the slide rail assemblies 37 are provided with pressure sensors, one end of the pressure sensor is fixedly connected with the slide rail assembly 37, the other end is fixedly connected with the mounting seat 33, and the slide rail assembly 37 is used to cause the mounting seat 33 to relatively deviate from the slide rail assembly 37 in the process of the battery cells 01 being combined under pressure.

[0081] In the above structure, the slide rail assemblies 37 are used to move the clamps 3 at both ends relative to the connecting block 36, and the movement amount can be converted to the pressure sensor, so as to facilitate the pressure sensor to monitor the extrusion force in the combining process.

[0082] In a preferred embodiment, each group of the transmission screw rod 25 is further provided with a reserved mounting seat 33 and a connecting block 36 and other related structures, so as to add corresponding clamps 3 according to actual production conditions, so as to improve production efficiency.

[0083] The clamp 3 of the present application can be used to receive the battery in a vertical state. After the battery is clamped, the rotary cylinder 31 is rotated by 90 degrees, the battery changes from a vertical state to a horizontal state, the pitch changing mechanism is actuated, the distance between the plurality of clamps 3 is pulled close, until the plurality of batteries are tightly attached together, until the required pressure is reached, and finally the conveying mechanism conveys the entire platform to the unloading position, completing the assembly.

If the specific posture changes, the directional indications will also change accordingly.
