Since most of the batteries 300 are flat in shape, the battery 300 is easily tilted when pressure is applied to one place on the upper surface of the battery 300. In this scheme, exert the pressfitting effort through pressure head 220 and compact heap 131 to two positions of battery 300 upper surface to the effort of the upper surface of guaranteeing battery 300 is more even, has avoided battery 300 atress offset, makes battery 300 more stable in year material station 1001.

There is a height difference between the first plane 310 and the second plane 320. It is necessary to press the first plane 310 and the second plane 320 simultaneously. Therefore, the pressing head part 220 and the pressing block 131 are correspondingly pressed on the first plane 310 and the second plane 320 in sequence.

Referring to fig. 6, fig. 6 is a schematic perspective view of a pressing assembly in a fixture mechanism according to some embodiments of the present disclosure. The compression assembly 200 also includes a sliding bracket 210. The ram portion 220 is slidably coupled to the sliding bracket 210. The sliding bracket 210 is erected on the second adjusting portion 140 and the long fixing bar 111, so that the sliding bracket 210 and the first adjusting portion 130 slide along the same first linear direction x. The sizes of the first plane 310 and the second plane 320 are different due to the limitation of the types of the batteries 300, and in order to ensure that the press head parts 220 and the press blocks 131 are correspondingly pressed on the first plane 310 and the second plane 320 in sequence, the sliding support 210 and the first adjusting part 130 can slide, so that the press head parts 220 and the press blocks 131 can move to the step-shaped upper surfaces of the batteries 300 with different sizes for pressing, and the jig mechanism is adaptive to the batteries 300 with different types.

Illustratively, the sliding frame 210 includes a gantry and a stringer 212. The portal frame comprises an upper beam 211 and a pressing block seat 213, wherein the pressing block seat 213 is arranged at two ends of the upper beam 211. The upper beam 211 and the supporting block 214 are respectively installed at two ends of the pressing block seat 213, and the supporting block 214 is respectively connected to the long fixing strip 111 and the long strip 141 in a sliding manner. Wherein, the quantity of portal frame is two, and two portal frames parallel arrangement. The two portal frames are connected by a cross beam 212, so that the portal frames and the cross beam 212 form a sliding support 210. The presser head 220 is provided on the stringer 212. At least two pressure head parts 220 are arranged on the same longitudinal beam 212, and the pressure head parts 220 are arranged on the longitudinal beam 212 along a first linear direction. More specifically, the number of the longitudinal beams 212 in the sliding bracket 210 is two, and the press heads 220 arranged on the two longitudinal beams 212 are symmetrically arranged, so that the press-fit acting forces of the press heads 220 on the two longitudinal beams 212 on the battery 300 are consistent, and the phenomenon that one side of the battery 300 is tilted due to an overlarge acting force applied to one side of the battery is avoided, and the test result is influenced.

According to some embodiments of the present application, the ram portion 220 conforms to the shape structure of the hold-down block 131. Take the indenter section 220 as an example. The pressure head part 220 includes an L-shaped pressure head body 221, and a sliding groove 222 extending in the vertical direction is formed on the pressure head body 221. The presser head part 220 is restricted by the slide groove 222 to slide in the vertical direction. The indenter body 221 includes an adjusting member (not shown) disposed at an end close to the battery 300, and the indenter body 221 includes a pressing plate end parallel to the horizontal plane at an end close to the battery 300. The adjusting piece is arranged on the pressure plate end. Illustratively, the adjusting member includes a bolt that is bolted to the end of the pressure plate, and the adjusting member is moved downward in the vertical direction by rotating the bolt. In order to ensure the pressing tightness, the pressing head body 221 needs to be fixed after moving to a fixed position, and the currently common fixing mode is a screw locking mode. However, in the case of the locking screw, it is difficult to ensure that the indenter body 221 is not displaced, i.e., during the process of fixing the indenter body 221, the displacement of the indenter body 221 is very likely to cause a change in the force for pressing the battery 300.

In this scheme, pressure head body 221 utilizes the bolt to make the regulating part further adjust the pressfitting effort to battery 300 after carrying out preliminary pressfitting for pressfitting battery 300's effort is more stable, and then keeps battery 300 in carrying material station 1001, avoids battery 300 offset.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the scope of the present invention.
