The bracket 11 can be made of a strong and light metal material, such as titanium alloy, aluminum metal, and magnesium alloy. The bracket 11 is provided with a connecting portion, and the bracket 11 is fixedly connected to an external transport mechanism through the connecting portion, and the transport mechanism drives the battery cell transfer device to lift and translate.

A plurality of suction nozzles 34 are evenly distributed on the adsorption surface 35. After the vacuum docking joint 5 is connected to an external vacuum source, the plurality of suction nozzles 34 generate adsorption force to adsorb the large surface of the battery cell. The role of the vacuum adsorption force is non-contact transportation. Arranging a plurality of suction nozzles 34 is conducive to evenly dispersing the adsorption force of the vacuum suction block to avoid excessive concentration of adsorption force to damage the battery cell; the vacuum suction module 1 is used to adhere to the battery cell and adsorb the battery cell through the adsorption surface 35.

[0033] The battery cell protection module 3 is arranged on the bracket 11, and the battery cell protection module 3 includes two relatively arranged protective members 22, and the two protective members 22 are arranged to be able to approach or move away from the battery cell to assist in adsorbing or releasing the battery cell, and the protective member 22 is provided with a supporting portion to support the bottom of the battery cell. Specifically, the protective member 22 is arranged as an "L"-shaped structure. When the two protective members 22 are close to each other, the bottoms of the two protective members 22 are respectively inserted into the bottom of the battery cell from both sides to support the battery cell.

[0034] In one embodiment of the present invention, referring to Figure 6As shown, the vacuum suction module 1 also includes a protective sponge 6, which is arranged in a square structure. The protective sponge 6 is attached to the adsorption surface 35. The protective sponge 6 is used for flexibly contacting the battery cell. During the transportation of the battery cell, the battery cell transfer device may descend too fast. When the battery cell stops, the battery cell transfer device keeps descending due to inertia, which may crush the battery cell. The protective sponge 6 can provide a buffer for the battery cell transfer device, and the protective sponge 6 is evenly distributed with multiple adsorption ports 33, and the multiple adsorption ports 33 are connected to multiple suction nozzles 34 and are arranged opposite to each other.

[0035] In one embodiment of the present invention, referring to Figure 1 and 4 As shown, the battery cell protection module 3 also includes a clamping cylinder 21, and a pair of the protective members 22 are respectively arranged at the two output ends of the clamping cylinder 21. When the vacuum suction block 7 adsorbs the battery cell, the clamping cylinder 21 is used to drive the pair of the protective members 22 to approach each other and insert into the bottom of the battery cell to support the battery cell, so as to prevent the battery cell from falling off due to insufficient adsorption force of the vacuum suction block 7; when the battery cell is transported to the placement position, the clamping cylinder 21 drives the pair of protective members 22 to move away from each other to release the battery cell; the vacuum suction block 7 is arranged on the inner side of a pair of the protective members 22, and the adsorption surface 35 has a height difference with the bottom of the protective member 22, so as to ensure that the protective member 22 can be inserted into the bottom of the battery cell.

[0036] In one embodiment of the present invention, referring to Figure 5 As shown, the battery cell protection module 3 also includes a first limit block 18 and a first buffer 19, the first limit block 18 and the first buffer 19 are used to adjust the opening and closing size of the jaw cylinder 21, the opening and closing sizes of the jaw cylinder 21 are different and match the size of the battery cell, and the battery cell transfer device can transfer battery cells of different sizes. Specifically, the first limit block 18 is fixedly connected to the cylinder body of the jaw cylinder 21, and the first limit block 18 is connected to one of the outputs 17; the first buffer 19 is installed on the buffer fixing block 20, and the buffer fixing block 20 is fixedly connected to the cylinder body of the jaw cylinder 21, and the first limit block 18 is blocked and limited by the first buffer 19 when the output end 17 of the jaw cylinder 21 moves to the open end, so that the output end 17 stops moving.

[0037] In one embodiment of the present invention, referring to Figure 4 As shown, the battery cell protection module 3 also includes two module fixing plates 26, and the two module fixing plates 26 are respectively fixedly connected to the two output terminals 17, and protective member fixing blocks 23 are slidably arranged on the two module fixing plates 26. A pair of protective members 22 are respectively fixedly connected to the protective member fixing blocks 23, and the protective members 22 and the protective member fixing blocks 23 are arranged to be able to rise and fall and slide along the module fixing plates 26.

[0038] In one embodiment of the present invention, referring to Figure 4 As shown, a slide rail 25 is provided on the module fixing plate 26, and the protective member 22 is slidably connected to the slide rail 25, and the slide rail 25 ensures that the protective member 22 slides accurately and smoothly.

[0039] In one embodiment of the present invention, referring to Figure 4 As shown, it also includes an induction detection module 2, which includes a sensor 28 and a sensor sheet 27, the sensor 28 has a sensing area 36, ​​the sensor 28 is fixedly connected to the module fixing plate 26, the sensor sheet 27 is fixedly connected to the protective member fixing block 23, and the sensor sheet 27 is located in the sensor 28, when the protective member fixing block 23 slides along the slide rail 25, the sensor sheet 27 is configured to pass through the sensing area 36 along the sliding direction of the protective member 22 to leave the sensor 28 and be sensed by the sensor 28, specifically, after the battery cell transfer device is transferred to the top of the battery cell target placement position, the battery cell transfer device descends as a whole and places the adsorbed battery cell into the battery cell target placement position, when used, the following situation is inevitable: that is, the battery cell has been placed at the current battery cell target placement position. At this time, after the battery cell transfer device is lowered as a whole, the protective member 22 and the protective member fixing block 23 are lifted up by the battery cell within the preset lowering stroke. At this time, the induction sheet 27 on the protective member fixing block 23 is raised at the same time, and the induction sheet 27 is separated from the induction area 36 of the sensor 28. The sensor 28 generates an alarm signal and transmits the alarm signal to the control device. After receiving the alarm signal, the control device controls the transfer mechanism to drive the battery cell transfer device to rise, and the alarm reminds that there are batteries at the placement position to avoid crushing the original batteries. If there are no batteries at the target placement position, the battery cell transfer device will be lowered as a whole. When it drops to the target distance, the two protective members 22 open, the vacuum suction block 7 releases the battery cell, and the battery cell transfer device rises as a whole again.

[0040] In one embodiment of the present invention, referring to Figure 4 As shown, it also includes a fixing profile 29 fixedly connected to the module fixing plate 26. The fixing profile is provided with a mounting groove, and the mounting groove extends along the sliding direction of the protective member 22. The sensor 28 can be fixed after sliding on the mounting groove, so as to facilitate the adjustment of the position of the sensor 28.

[0041] In one embodiment of the present invention, referring to Figure 4As shown, the module fixing plate 26 is also provided with a guide rod and an elastic element 24 sleeved on the guide rod, the elastic element 24 is arranged between the protective member fixing block 23 and the module fixing plate 26, and the two ends of the elastic element 24 respectively abut the module fixing plate 26 and the protective member fixing block 23, the elastic element 24 is implemented as a spring, and is used to buffer the protective member 22 and the battery cell. During the descent of the battery cell, at the moment when the battery cell transfer device stops descending, the protective member keeps descending due to inertia, and the elastic element 24 can buffer the protective member 22, thereby avoiding a violent collision between the battery cell and the placement position; one end of the guide rod is fixed by the guide rod fixing plate 30.

[0042] In one embodiment of the present invention, referring to Figure 1 and 3 As shown, it also includes a battery cell rotating module 4, which includes a rotating cylinder 13. The rotating cylinder 13 drives the bracket 11 to rotate, so as to adjust the placement angle of the battery cell to match different placement positions.

[0043] In one embodiment of the present invention, referring to Figure 1 and 3 As shown, the battery cell rotation module 4 also includes a second buffer 14, the second buffer 14 is fixedly connected to the buffer fixing seat 15, the buffer fixing seat 15 is fixedly connected to the cylinder body of the rotating cylinder 13, the bracket 11 is provided with two second limit blocks 12, the second buffer 14 is used to limit the rotation angle of the two second limit blocks 12, the second buffer 14 is fixedly set on the rotation trajectory of the two second limit blocks 12, specifically, in this embodiment, any second limit block 12 can contact the second buffer 14 after rotating up to 90°, so that the bracket 11 stops rotating.

[0044] The working principle of the battery cell transfer device of the utility model is:

[0045] The protective member 22 of the battery cell protection module 3 is opened, and the battery cell rotation module 4 adjusts the vacuum suction fastener to align the battery cell. Under the drive of the transfer mechanism, the vacuum suction block 7 descends and adheres to the surface of the battery cell to absorb the battery cell. After the battery cell is lifted, the two protective members 22 close and support the battery cell to assist in absorption. After the battery cell is lifted, the rotating cylinder 13 drives the bracket 11 to rotate 90 degrees to adjust the battery cell placement angle. The battery cell is transported to the top of the placement position and then descends. During the descent process, if there is a battery cell at the placement position, the protective member 22 and the protective member fixing block 23 are lifted by the battery cell below, and the induction sheet 27 rises at the same time and disengages from the sensor 28. The sensor 28 generates an alarm signal. After the control device receives the alarm signal, the battery cell transfer device rises, and the alarm reminds that there is a battery cell at the placement position. The battery cell transfer device stops descending until the alarm signal is released. If there is no battery cell at the placement position, the protective member 22 opens after the battery cell is placed at the placement position, and the vacuum suction fastener releases the battery cell, and then the battery cell transfer device rises as a whole.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
