The supporting plate 2 can be lifted and lowered on the bottom plate 1 to ensure that the top of the battery cell 00 is flush with the top surface of the baffle 3 to meet the positioning of battery cells 00 of different thicknesses. This structure can achieve the positioning of battery cells 00 of different lengths, widths and thicknesses, has good compatibility, and can reduce costs.

[0051] In some embodiments, the cell Mylar hot melt tooling further includes a pushing assembly 6, which includes a connector 61, a mounting plate 62, a toggle clamp 63, and two first guide shafts 64. The connector 61 is used to connect the carrier plate 2 and the mounting plate 62. The pressure plate 4 is provided with two first guide holes 41. One end of the first guide shaft 64 is fixed to the mounting plate 62, and the other end is slidably installed in the two first guide holes 41. The toggle clamp 63 is installed on the mounting plate 62, and the output shaft of the toggle clamp 63 is pressed against the pressure plate 4. When the pressure plate 4 pushes the cell 00 to press against the baffle 3, the side push plate 5 is adjusted to ensure that the cell 00 does not move in the second direction, and the pressure plate 4 is moved back a certain distance to ensure that the toggle clamp 63 has a movable distance. The toggle clamp 63 is pressed so that the cell 00 is clamped between the baffle 3 and the pressure plate 4. The carrier plate 2 and the mounting plate 62 are connected and fixed by the connector 61, thereby achieving the positioning and fixation of the cell 00 in the first direction.

The two second guide shafts 72 are parallel to the adjusting bolt 71, with one end fixedly connected to the support plate 2 and the other end movably mounted on the base plate 1. The rotation of the adjusting bolt 71 drives the support plate 2 to rise and fall along the second guide shafts 72, thereby ensuring that the top surface of the cell 00 is always flush with the top surface of the baffle 3, allowing for the positioning of cells 00 of varying thicknesses.

[0054] In some embodiments, the base plate 1 is provided with an avoidance hole 11 to allow the support plate 2 to pass through; the lifting assembly 7 also includes a mounting block 73, the mounting block 73 being fixed to the end surface of the base plate 1 away from the side thrust plate 5, the mounting block 73 being provided with a second guide hole 731 and a threaded hole 732, the second guide shaft 72 being slidably mounted in the second guide hole 731, and the adjusting bolt 71 being threadedly connected to the threaded hole 732.

The fixed block 82 is installed at the bottom of the carrier plate 2. The fixed block 82 is provided with a slide groove. One end of the sliding bar 83 is slidably installed in the slide groove, and the other end is connected to the support bar 81. By sliding the sliding bar 83 along the slide groove, the spacing between the two support bars 81 can be adjusted, and the width of the bottom support of the battery cell 00 can be adjusted to meet the support of different widths of the battery cell 00 in the second direction, thereby improving reliability. In this embodiment, when the support bar 81 is in contact with the carrier plate 2, the avoidance hole 11 can allow the support bar 81 to pass through together with the carrier plate 2, which is suitable for battery cells 00 with small width and large thickness, thereby improving compatibility.

[0057] In some embodiments, the battery cell Mylar hot melt tooling further includes a sliding stay 10 and a fastener 110. The sliding stay 10 is slidably mounted on the side of the baffle 3 and supported below the pole of the battery cell 00. The fastener 110 is used to secure the sliding stay 10 to the baffle 3. The two ends of the sliding stay 10 are clamped on the two sides of the baffle 3. When the sliding stay 10 slides to fit the bottom surface of the pole of the battery cell 00, the fastener 110 connects and secures the sliding stay 10 to the baffle 3, supporting the battery cell 00 below the position of the cover plate 9 near the baffle 3, thereby improving the stability and reliability of the device.

[0058] In some embodiments, a guide groove 12 is provided on the base plate 1 along the second direction, and a plurality of second mounting screw holes 121 are provided at equal intervals in the guide groove 12.

The third connecting screw 130 is used to pass through the connecting hole 1201 and connect with the second mounting screw hole 121. The slider 120 slides along the guide groove 12 to drive the side push plate 5 to move. When the two side push plates 5 clamp the battery cell 00, the third connecting screw 130 passes through the connecting hole 1201 and connects with the second mounting screw hole 121, thereby achieving a fixed connection between the side push plate 5 and the base plate 1, thereby positioning and fixing the battery cell 00 in the second direction.

[0059] In some embodiments, the cell Mylar hot melt fixture further includes reinforcing ribs 140, which are respectively connected to the bottom plate 1 and the side of the baffle 3 away from the carrier plate 2. The reinforcing ribs 140 are respectively connected to the bottom plate 1 and the side of the baffle 3 away from the carrier plate 2, thereby increasing the strength of the baffle 3. Therefore, when the pressure plate 4 pushes the cell 00 into contact with the baffle 3, the bottom plate 1 and the pressure plate 4 can jointly bear the force, thereby increasing the service life of the device.

[0060] The working principle of this battery cell Mylar hot melt fixture is as follows: the pressure plate 4 is movably mounted on the carrier plate 2 and can push the battery cell 00 toward the baffle 3. The two side push plates 5 are movably mounted on the base plate 1 and can move toward each other to meet the positioning requirements of battery cells 00 of different lengths and widths. The carrier plate 2 can be raised and lowered on the base plate 1 to ensure that the top of the battery cell 00 contacts the cover plate 9, meeting the positioning requirements of battery cells 00 of different thicknesses. This structure can achieve the positioning of battery cells 00 of different lengths, widths, and thicknesses, has good compatibility, and can reduce costs.
