[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] A light curing component 1, referring to Figure 1 , including a fixing block 11, a mounting groove is opened on the top wall of the fixing block 11, and a long strip light source 12 is installed in the mounting groove. In the embodiment of the present application, two fixing blocks 11 are symmetrically arranged, and the light source 12 is a long strip of ultraviolet light strip; in other embodiments, the number of fixing blocks 11 and light sources 12 can be increased or decreased according to actual usage, or the light source 12 with other wavelengths can be replaced.

[0035] Reference Figure 1-3 , driving cylinders 13 are symmetrically arranged on both sides of the top of the light source 12, and the driving ends of the driving cylinders 13 are arranged opposite to each other and are connected to a pair of L-shaped clamps 14. The two L-shaped clamps 14 are arranged at opposite angles and move toward or away from each other under the driving action of the driving cylinders 13; each clamp 14 includes a supporting plate 141 and an abutment plate 143 that are connected to each other, wherein the supporting plate 141 is arranged parallel to the side wall of the side where the mounting groove is provided with the fixed block 11, and the abutment plate 143 is arranged on the side of the supporting plate 141 away from the light source 12, and the abutment plates 143 of the two clamps 14 are arranged opposite to each other. In other embodiments, the supporting plate 141 and / or the abutment plate 143 can also be extended for other considerations to form a T-shaped or cross-shaped clamp 14, and reinforcing ribs can be provided on the extended plate to improve the stability of the clamp 14.

[0036] Reference Figure 2The support plate 141 is also provided with a transmission hole 142 for transmitting light. In the embodiment of the present application, the transmission hole 142 is arranged on the side of the support plate 141 close to the abutment plate 143, so that the light passing through the transmission hole 142 enters the concave corner of the clamp 14, and further makes the side wall of the transmission hole 142 flush with the side wall of the abutment plate 143, so that the light source 12 can directly illuminate the folding position, thereby improving the light curing efficiency, reducing the occurrence of insufficient glue curing, and improving the quality of battery products. In other embodiments, in order to increase the acceptable range of the light source 12 at the glue dispensing position and reduce the occurrence of insufficient light curing caused by the misalignment of the light source 12 and the transmission hole, the two oppositely arranged side walls of the transmission hole 142 can also be respectively arranged on both sides of the side wall of the support plate 141.

[0037] In this application, in order to further improve the stability of the clamp 14, refer to Figure 3 A bracket 15 is connected to the convex corner of the L-shaped clamp 14. The bracket 15 includes a connecting portion 151 connected to the driving end and the abutment plate 143 on both sides, and a supporting portion 152 connected to the supporting plate 141. The supporting portion 152 is two plates arranged at intervals. When the clamp 14 is connected to the driving end through the bracket 15, the side wall of the supporting portion 152 does not protrude from the side wall of the transmission hole 142, so that the transmission hole 142 is completely exposed, ensuring the smooth progress of the light curing process.

[0038] After completing the battery folding, hot-pressing and gluing process, the staff needs to operate the transfer device to transfer the battery to the position of the clamp 14, and then slide the clamp 14 so that the two abutment plates 143 are respectively pressed against the folded edges of the battery. By light-curing the applied glue in the clamped state, the curing bonding strength can be effectively improved to ensure the structural stability of the battery.

[0039] Reference Figure 1 To facilitate the efficient light curing process for batteries of different specifications, position adjustment plates 16 are connected to the side walls of the fixed block 11 at both ends of the length direction of the light source 12. A connecting piece 17 is detachably provided on the side of the position adjustment plate 16 away from the fixed plate. The connecting piece 17 is spoon-shaped, wherein the spoon head is detachably connected to the fixed block 11, and the spoon handle is connected to the installation location. During use, the installation position of the light source 12 can be adjusted according to the required light curing position of the battery. The position adjustment plate 16 is provided with an elongated mounting hole 161; the light source 12 is detachably connected to the position adjustment plate 16 through the cooperation of bolts and the mounting hole, and the position of the light source 12 can be adjusted by adjusting the relative position of the fixed plate and the mounting hole to improve the utilization rate of the light source 12. In other embodiments, the fixed block 11 can also be directly fixed and installed by other conventional connection methods such as bolts, welding, and bonding according to actual needs.

[0040] Example 2

[0041] A photocuring assembly 1 differs from Example 1 in that two light sources 12 are respectively arranged corresponding to two transmission holes 142, and a connecting rod is further connected to the side of the two fixing blocks 11 arranged opposite to each other. The connecting rod is connected to the driving end of the driving cylinder 13 and moves synchronously with the clamp 14 under the action of the driving cylinder 13. This arrangement can effectively reduce the occurrence of misalignment between the light source 12 and the transmission hole 142, thereby improving the photocuring efficiency.

[0042] Application Example 1

[0043] A weighing device, referring to Figure 4 , including a weighing assembly 2 for weighing and testing batteries, a transfer member (not shown) for transferring batteries, and the light-curing assembly 1 of Example 1; in this application, the transfer member is a suction cup, which is arranged on the top of the light-curing assembly. The light-curing assembly 1 is arranged on the top of the weighing assembly 2. When the battery that has been folded and glued is transferred to the position where the weighing assembly 2 is located, the staff can first activate the light source 12 to further cure the glue through the light-curing assembly 1, and then grab the battery through the transfer member and place it on the weighing assembly 2 for weighing.

[0044] Reference Figure 4 The weighing assembly 2 includes a weighing piece 21, a weighing frame 22 arranged on the top of the weighing piece 21 and connected to the weighing tray, and a placement plate 23 connected to the top of the weighing frame 22. In the present application, the weighing piece 21 is an electronic scale, and the placement plate 23 is a transparent plate; the light source 12 fixing block 11 is arranged between the placement plate 23 and the weighing piece 21, and there is a gap between the light source 12 and the placement plate 23, and the light source 12 is arranged toward the placement plate 23; the clamp 14 is arranged on the side of the placement plate 23 away from the weighing piece 21. In addition, during use, the driving cylinder 13 and the connecting piece 17 are both connected to a wall or frame structure that is separated from the weighing piece 21 and fixed in position, and when the driving cylinder 13 is in the minimum driving distance state, the projections of the clamp 14 and the placement plate 23 on the horizontal plane do not overlap, thereby reducing the occurrence of mutual interference between the two devices.

[0045] After the battery is transferred to the position of the fixture 14 via the transfer member, the drive cylinder 13 is activated, which drives the fixture 14 to move, pressing the battery's folded edge against the battery body. The glue is then photocured in this state, further improving the stability of the battery structure. After the photocuring operation is completed, the drive fixture 14 moves away from the battery until it is completely separated. The battery is then placed on the placement plate 23 for weighing via the transfer member. The photocuring process continues simultaneously during the weighing process, further improving the stability of the battery structure.

[0046] Application Example 2

[0047] A weighing device, referring to Figure 5, which differs from Application Example 1 in that a bracket 24 is attached to the bottom of the driving cylinder 13, which is directly connected to the placement plate 23. The light source 12 is placed between the placement plate 23 and the fixture 14. In this case, because the driving cylinder 13 is directly connected to the weighing member 21 via the placement plate 23 and the fixture 14 is supported by the driving cylinder 13, once the battery is placed on the fixture 14, the battery mass can be directly determined by the change in the reading on the weighing member 21, which is convenient and quick.
