The assembly module 2 includes a positioning jig 21 for assembling the battery module cover. The riveted battery module cover is assembled on the positioning jig 21 with the foam bonding surface facing upward.

[0025] The front of the loading port 11 faces the operator, and the operator can manually place the battery module cover to be foam-laminated on the positioning fixture 21, or can use other loading components to achieve automatic loading, which is not limited.

[0026] The laminating module 3 is mounted on the workbench 12 within the frame 1 and includes a foam pressing assembly 31 that is movable horizontally above the positioning fixture 21. The horizontal movement direction of the foam pressing assembly 31 is defined as a first direction, and the direction perpendicular to the first direction on the horizontal plane is defined as a second direction. The laminating module 3 also includes a first movable module 32 that drives the foam pressing assembly 31 in the first direction. The foam pressing assembly 31 is connected to the travel output end of the first movable module 32 via a cantilever.

[0027] Specifically, the first movable module 32 is fixedly mounted on a mounting frame 33 , and the mounting frame 33 is further provided with a linear guide rail 34 extending along a first direction. Driven by the first movable module 32 , the foam pressing component 31 is slidably connected to the mounting frame 33 through the linear guide rail 34 .

[0028] like Figure 3 The foam pressing assembly 31 includes a foam-applying jig 311 for positioning the foam and a pressing plate 312 for pressing the foam. The foam-applying jig 311 and pressing plate 312 are driven vertically by a positioning driver and a pressing driver, respectively. In this embodiment, the positioning driver and the pressing driver are a positioning cylinder 313 and a pressing cylinder 314, respectively. The foam-applying jig 311 and pressing plate 312 are connected to the piston rod output ends of the positioning cylinder 313 and the pressing cylinder 314, respectively.

[0029] The end of the cantilever is fixedly connected to a mounting plate, with a positioning cylinder 313 and a pressing cylinder 314 positioned on opposite sides of the mounting plate. The positioning jig 21 is equipped with a positioning block 22 for quickly positioning the battery module cover. The foam application jig 311 is provided with a clearance hole 315 and a positioning hole 316.

The foam sticking jig 311 is pressed against the corresponding position on the battery module cover under the drive of the positioning cylinder 313, and then the foam with the adhesive side facing downwards is placed on the corresponding foam attachment position of the upper battery module cover along each positioning hole 316, then the piston rod of the pressing cylinder 314 is extended, and drives the pressure head to press down to complete the foam attachment, and finally the piston rods of the pressing cylinder 314 and the positioning cylinder 313 are retracted in turn.

[0032] Furthermore, a pressure sensor 318 is provided between the pressure plate 312 and the piston rod output end of the pressing cylinder 314. The pressure sensor 318 is used to monitor the downward pressure of the piston rod output end of the pressing cylinder 314 in real time. The control module uses the pressure signal fed back by the pressure sensor 318 to achieve precise control of the movement of the pressing cylinder 314.

[0033] In order to avoid displacement of the battery module cover during the foam bonding process, Figure 4 and Figure 6 A pressing mechanism 4 is provided at the strip notch 1-1 on the positioning jig 21 corresponding to the battery module cover.

The control module confirms the information photographed and recorded by the first camera assembly 51 and the second camera assembly 52.

[0035] In order to be applicable to the foam bonding and riveting detection of various battery module covers, such as Figure 7 As described above, the riveting inspection of the battery module cover requires double-sided inspection. In this embodiment, a flip module 6 for flipping the positioning jig 21 is further provided below the positioning jig 21. The flip module 6 includes a flip frame 61 for supporting the positioning jig 21 and flip brackets 62 located at both ends of the positioning jig 21 along the second direction.
