Each protective bracket positioning and installation device includes a protective bracket positioning mechanism 40 and a protective bracket installation mechanism 41. The output end of the protective bracket installation mechanism 41 is provided with the protective bracket positioning mechanism 40. The protective bracket positioning mechanism 40 is positioned in correspondence with the cell end positioning mechanism so that the protective bracket can be inserted into the cell end for protection.

[0035] The above-described embodiments of the present invention realize a protective bracket guide fixture based on the top surface of the battery cell, which guides the protective bracket to be assembled based on the upper plane and the top surface of the battery cell, ensuring accurate installation and positioning of the protective bracket, low scrap rate and high production efficiency.

[0036] like Figure 3 As described above, the battery cell side positioning mechanism 30 includes a battery cell side positioning drive component, a first positioning gripper 300 and a second positioning gripper 301. The battery cell side positioning drive component can drive the first positioning gripper 300 and the second positioning gripper 301 to be in an open or locked state.

[0037] like Figure 3 As shown, the cell top surface positioning mechanism 31 includes a cell top surface driving component 310 and a guide component 311. The cell top surface driving component 310 is connected to the cell side surface positioning mechanism 30 and is used to drive the cell that has been positioned by the cell side surface positioning mechanism 30 to move along the guide component 311 to the height positioning reference.

[0038] like Figure 3 As shown, the first positioning gripper 300 and the second positioning gripper 301 each include a gripper side plate and a gripper base, and the gripper side plate and the gripper base are vertically connected.

[0041] To facilitate understanding of the working principle of this invention, the working principle of this embodiment is explained below:

[0042] like Figure 1 As shown in the figure, this embodiment uses two sets of upper-layer protective bracket positioning units and two sets of lower-layer protective bracket positioning units, with each set of upper-layer protective bracket positioning units including four upper-layer protective bracket positioning structures, and each set of lower-layer protective bracket positioning units including four lower-layer protective bracket positioning structures as an example to illustrate the working principle as follows:

[0043] First, the four upper-layer protective bracket positioning structures 10 and four lower-layer protective bracket positioning structures 11, which have already been placed, are manually moved to the loading platform. The base plate of the loading platform has a positioning and anti-misalignment design to ensure the positional accuracy of the protective brackets after placement. At this time, the detection device judges whether the four upper-layer protective bracket positioning structures 10 and four lower-layer protective bracket positioning structures 11 and the protective brackets are placed correctly and whether any protective brackets are missing. Next, the four upper-layer protective bracket positioning structures 10 and four lower-layer protective bracket positioning structures 11 slide to the position of the transport and adjustment device 2. The program controls the negative pressure suction mechanism, i.e., the suction cup, to grab the protective brackets in the four upper-layer protective bracket positioning structures 10 and load them. After loading is completed, the protective brackets in the four lower-layer protective bracket positioning structures 11 are then grabbed. The four upper-layer protective bracket positioning structures 10 and four lower-layer protective bracket positioning structures 11 are loaded alternately and cyclically to ensure that the loading does not stop and the efficiency is high. At this point, the three-axis transport module 20 transports the device to the protective bracket positioning and installation device 4 (four protective bracket positioning and installation devices are also set here). During the transport process, the pitch can be adjusted by the pitch-changing mechanism 21 to achieve the required spacing between the protective bracket positioning and installation devices. ， This also ensures that the spacing of the protective brackets matches the spacing of the battery cells. Simultaneously, the battery cell positioning device 3 (corresponding to four battery cell positioning devices) activates, with the side positioning mechanism 30 laterally positioning the battery cells, and then the top positioning mechanism 31 pulls the battery cells to the top positioning reference point, preferably the upper positioning plate. At this point, all four battery cells have reached the reference positioning point. The aforementioned three-axis transport module 20 transports the protective brackets to the protective bracket positioning mechanism 40 for positioning. The protective bracket installation mechanism 41 then installs the protective brackets along the battery cell guide to the battery cell end face. During installation, the floating component (spring) flexibly adapts to the irregular structure of the battery cell end, assisting in the installation of the protective brackets.
