[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) Start the clamping motor, so that the clamping block on its output end drives the clamping gear to rotate through the clamping groove, and then the two clamping racks are meshed and moved, so that the clamping racks are moved on the clamping base plate through the clamping rod, and the two linkage horizontal plates are driven to move toward each other through the U-shaped ring, L-shaped column and lowering square tube, and the fitting square plate is driven to move through the linkage round rod and linkage spring, so that the plastic buffer pad on the fitting square plate contacts the side of the battery module, and the plastic buffer pad has a certain plasticity and a buffering effect, so that the plastic buffer pad is in The linkage horizontal plate is in a buffering state. At this time, the linkage horizontal plate continues to be moved, so that the several linkage springs are in a buffering state. As a result, the surface of the shaped buffer pad is deformed by applying external force to the shaped buffer pad through the fitting square plate. The changed shape is the same as the appearance of the clamped battery module. Therefore, the linkage clamping assembly can adapt to different types of battery modules, so that the two shaped buffer pads wrap the sides of the battery module, thereby completing the clamping operation of the battery module. By operating the arm on the handling robot, the clamped battery module can be stably transported to the battery box. Due to the different types of battery modules, their appearances are also different. Through the above structure, it is avoided to replace different clamps when transporting different types of battery modules, which reduces the limitations of the device during use, thereby improving the handling efficiency and stability of the device.

[0017] (2) After the fitting square plate has contacted the side of the battery module, continue to push the linkage horizontal plate, so that the linkage horizontal plate moves within the upper limit of the linkage round rod, and then the distance block on the linkage horizontal plate gradually enters the distance sleeve provided on the fitting square plate, so that the static contact piece contacts the moving contact piece, thereby sending a signal to the control block, and sending an interrupt signal to the clamping motor through the control block, so that the clamping motor stops working, avoiding the battery module being damaged by excessive force when the joint clamping and moving assembly is used, so that the device can terminate the operation according to the different lengths of different battery modules, reducing the workload of the operator, so that the operator does not have to keep an eye on the use of the device, so that the clamping force provided by the joint clamping and moving assembly to the battery modules of different lengths is the same, avoiding damage to the battery modules due to poor control of the force when clamping and moving battery modules of different lengths, thereby improving the efficiency of transportation; at the same time, when the signal is sent to stop the clamping motor, a signal is simultaneously sent to the alarm unit, and an alarm is sounded to alert the operator;

[0018] (3) By pulling the pull ring outward, the guide block moves within the upper limit of the guide square rod, so that the guide spring is in a buffering state, so that the rectangular oblique rod on the guide block is no longer connected to the locking groove and the rectangular square groove, thereby releasing the limit setting of the lowering square column, and then by pulling the handle upward, the linkage U rod on the linkage horizontal plate moves within the upper limit of the positioning base through the symmetrically arranged positioning round rod, thereby improving the stability of the linkage horizontal plate during movement, so that the lowering square column on the linkage horizontal plate can move within the upper limit of the lowering square tube, and then the fitting square plate and the shaping buffer pad on the linkage horizontal plate and other parts move together, so that the height of the fitting square plate can be adjusted to avoid the device being used in production lines with different heights. The large distance between the battery module and the battery module makes it difficult to carry the battery module, thereby reducing the limitations of the device when in use, so that the shaped buffer pad on the fitting square plate can be clamped at different heights of the battery module, avoiding the contact surface between the shaped buffer pad and the battery module being too small, resulting in an unstable position during transportation and causing the battery module to fall, thereby increasing the practicality of the device; when the operator adjusts the height of the fitting square plate according to the height of the production line and the battery module, the pull ring is released, and the rectangular diagonal rod is reset by the reset of the guide spring, so that the rectangular diagonal rod passes through the rectangular square groove and is connected to any locking groove on the lowering square column, thereby limiting the fitting square plate on the lowering square column at the current height, thereby improving the handling efficiency of the device;

[0019] (4) When the two second hinge blocks move away from each other, one of the second hinge blocks moves toward the installation square plate, thereby driving the locking U plate to approach the installation square plate, indicating that the toothed contact unit and the joint clamping assembly have moved into place. Then, a start signal is sent to a number of electric retractors through the control block to move the locking plates on their output ends, so that the two locking plates move toward each other, thereby connecting with the installation square plate and clamping the installation square plate, thereby limiting the drive plate on the toothed contact unit at the current position, thereby preventing the battery module from falling due to the large shaking during the transportation of the battery module, thereby improving the stability of the device in transporting the battery module;

[0020] (5) When the touch plate is attached to the side of the battery module, the driving plate continues to move, and the two sliders move back to back on the slide rod through the first hinge block, the hinge plate and the second hinge block, and the tension spring is in a buffering state, thereby providing a buffering force that can absorb the impact force caused by the shaking of the battery module during transportation, thereby improving the stability of the battery module during transportation. Since different types of battery modules have different lengths and widths, the touch plate is prevented from contacting the side of the battery module too early to affect the normal operation of the device, thereby reducing the limitations of the device during use;

[0021] (6) The positioning bevel gear on the positioning shaft starts to rotate and engages with the two rotating bevel gears to rotate, so that the rotating threaded shaft rotates on the U-shaped base, and then drives the threaded torque square plate to move, so that the torque square plate moves within the upper limit of the limit base through the limit rod on the limit plate, so that the two driving plates on the two torque square plates move toward each other, so that the two touch plates move toward each other, so that the rubber layer of the touch plate contacts the side of the battery module, increasing the friction between the touch plate and the battery module, thereby clamping the other two sides of the battery module, and assisting the use of the joint clamping and moving assembly to avoid slipping or shaking when transporting the battery module, thereby improving the stability of the battery module when being transported;

[0022] (7) When it is necessary to operate the quick-action distance mechanism to adjust the height of the linkage horizontal plate, the locking bevel block can only be pulled downward to limit its movement in the locking sleeve, and the locking spring is in a buffering state, so that the locking bevel block is no longer connected to the locking bevel groove, and the limit setting of the rectangular bevel rod is released, so that the quick-action distance mechanism can normally adjust the height of the linkage horizontal plate; when the adjustment is completed, the inclined surface on the reset rectangular bevel rod contacts the inclined surface on the locking bevel block, so that the locking bevel block limits its movement in the locking sleeve, and the locking spring is in a buffering state. When the locking bevel block contacts the locking bevel groove, the locking bevel block is reset and moved into the locking bevel groove by the reset of the locking spring, thereby limiting the rectangular bevel rod, so that the right-angle surface of the rectangular bevel rod is connected to the right-angle surface on the corresponding locking bevel groove, avoiding the rectangular bevel rod from moving due to non-human factors, thereby improving the stability of the coupling clamping assembly during use.

[0046] When the fitting square plate 25 has contacted the side of the battery module, the linkage horizontal plate 14 is continuously pushed, so that the linkage horizontal plate 14 moves within the upper limit position of the linkage round rod 23, and then the distance block 50 on the linkage horizontal plate 14 gradually enters into the distance sleeve 51 provided on the fitting square plate 25, so that the static contact piece 52 contacts the moving contact piece 53, thereby sending a signal to the control block 54, and the control block 54 sends an interrupt signal to the clamping motor 4, so that the clamping motor 4 stops working, so as to avoid the damage to the battery module caused by excessive force when the coupling clamping assembly is used, so that the device can The operator can decide to terminate the operation according to the different lengths of the battery modules, which reduces the workload of the operator and eliminates the need for the operator to keep an eye on the use of the device. The device can provide the same clamping force to the battery modules due to the different lengths of the battery modules, thus avoiding damage to the battery modules due to poor control of the force when clamping and transporting the battery modules of different lengths, thereby improving the transportation efficiency. At the same time, when a signal is sent to stop the clamping motor 4, a signal is synchronously sent to the alarm unit to sound an alarm to alert the operator.

[0047] refer to Figure 8 The slow energy absorption component of this embodiment includes two first hinge blocks 55 symmetrically arranged on the touch plate 48, each first hinge block 55 is connected to a second hinge block 57 through a hinge plate 56, and a slider 58 is installed on each second hinge block 57.

[0048] When the touch plate 48 is attached to the side of the battery module, the drive plate 47 continues to be moved, and the two sliders 58 move opposite to each other on the slide rod 59 through the first hinge block 55, the hinge plate 56 and the second hinge block 57, and the tension spring 61 is in a buffering state, thereby providing a buffering force that can absorb the impact force caused by the shaking of the battery module during transportation, thereby improving the stability of the battery module during transportation. Since the lengths and widths of different types of battery modules are also different, the touch plate 48 is prevented from contacting the side of the battery module too early to affect the normal operation of the device, thereby reducing the limitations of the device during use.

[0049] refer to Fig. 9The locking unit of this embodiment includes a locking inclined groove 62 provided on the rectangular inclined rod 20, the locking inclined groove 62 is connected with the locking inclined block 63, the locking inclined block 63 is slidably connected with the locking sleeve 64 provided on the lowering square tube 12, and the inner bottom surface of the locking sleeve 64 is connected with the locking inclined block 63 through a locking spring 65;

[0050] When the height of the linkage horizontal plate 14 needs to be adjusted, the locking bevel 63 can only be pulled downward to limit the movement of the locking sleeve 64, and the locking spring 65 is in a buffering state, so that the locking bevel 63 is no longer connected to the locking bevel groove 62, and the limiting setting of the rectangular oblique rod 20 is released, so that the agile distance mechanism can normally adjust the height of the linkage horizontal plate 14; when the adjustment is completed, the inclined surface on the reset rectangular oblique rod 20 contacts the inclined surface on the locking bevel 63, so that the locking bevel 63 moves in the locking sleeve 64, and the locking spring 65 is in a buffering state. When the locking bevel 63 contacts the locking bevel groove 62, the locking bevel 63 is reset and moved into the locking bevel groove 62 by the reset of the locking spring 65, thereby limiting the rectangular oblique rod 20, so that the right-angled surface of the rectangular oblique rod 20 is connected with the corresponding right-angled surface on the locking bevel groove 62, avoiding the rectangular oblique rod 20 from moving due to non-human factors, and improving the stability of the connecting clamping and moving assembly when in use.

An electric retractor 68 is symmetrically arranged on the locking U-plate 67. A locking plate 69 is installed on the output end of the electric retractor 68. The plurality of locking plates 69 are connected to the mounting square plate 1 in cooperation with each other; the electric retractor 68 is connected to the control block 54 in cooperation with each other;

[0052] When the two second hinge blocks 57 move away from each other, one of the second hinge blocks 57 moves toward the mounting square plate 1, thereby driving the locking U plate 67 to approach the mounting square plate 1, indicating that the toothed unit and the coupling clamping assembly have moved into place, and then a start signal is sent to a number of electric telescoping devices 68 through the control block 54 to move the locking plates 69 on their output ends, so that the two locking plates 69 move toward each other, thereby connecting with the mounting square plate 1 and clamping the mounting square plate 1, thereby limiting the drive plate 47 on the toothed unit to the current position, thereby avoiding large shaking during the transportation of the battery module, which drives the drive plate 47 to move and causes the battery module to fall, thereby improving the stability of the device in transporting the battery module.
