[0029] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0030] In the present disclosure, unless otherwise stated, directional words such as "upper and lower" generally refer to the upper and lower parts of the hot-melt device of the cell spacer side plate in normal use, and "inside and outside" refer to the inside and outside relative to the contour of the corresponding component itself. The terms "first", "second", etc. used in the present disclosure are intended to distinguish one element from another and do not have order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0031] According to a specific embodiment of the present disclosure, a hot-melt device for a side plate of a battery cell spacer is provided, referring to Figures 1 to 5As shown, the hot-melt device for the side plate of the battery cell spacer ring may include a substrate 1, a battery cell clamping module 2 and a hot-melt module 3, wherein the battery cell clamping module 2 may include a support platform 21 and a positioning component 22, the support platform 21 may be fixedly connected to the substrate 1 to horizontally support the battery cell 100 on the substrate 1, the positioning component 22 may position the battery cell 100 on the support platform 21 along the length direction and the width direction of the battery cell 100, so that the battery cell 100 is horizontally positioned relative to the substrate 1, and the hot-melt module 3 may have four, and each two hot-melt modules 3 form a group, and the same group The two hot melt modules 3 can be relatively arranged on both sides of the support platform 21 along the width direction of the battery cell 100, and are arranged at a position aligned with the boss 102 of the battery cell spacer 101. That is, along the length direction of the battery cell 100, a group of hot melt modules 3 can be respectively arranged at positions corresponding to the two ends of the battery cell 100 to heat the boss 102 of the battery cell spacer 101 at both ends of the battery cell 100. The hot melt module 3 may include a heating component 31, and the heating component 31 can move along the width direction of the battery cell 100 to contact or move away from the boss 102. Figure 2 As shown, when the heating component 31 contacts the boss 102 , the boss 102 can be heated and the battery cell 100 can be clamped to prevent the battery cell 100 from shifting and causing the boss 102 to be disengaged from the heating component 31 .

[0032] Through the above technical solution, the hot-melt device for the side plate of the battery cell spacer disclosed in the present invention can horizontally support and position the battery cell 100 on the substrate 1 through the battery cell clamping module 2, and then the heating component 31 of the hot-melt module 3 can move along the width direction of the battery cell 100 to clamp the battery cell 100, and at the same time, the heating component 31 can heat the boss 102 of the battery cell spacer 101 to melt the boss 102, so as to form an effective connection between the boss 102 and the side plate 103 of the battery cell 100. Through the hot-melt device for the side plate of the battery cell spacer provided in the present invention, the effective connection between the boss 102 of the battery cell spacer 101 and the side plate 103 can be efficiently achieved, and the consistency of the product can also be improved.

[0033] In order to position the battery cell 100 along the length direction and the width direction, refer to Figure 1 and Figure 3As shown, the positioning assembly 22 may include a first stopper 221 and a second stopper 222, wherein the first stopper 221 may be fixedly connected to the edge of the support platform 21 extending along the length direction of the battery cell 100, that is, the first stopper 221 may stop at one side of the battery cell 100 in the width direction of the battery cell 100 to position the battery cell 100 along the width direction of the battery cell 100, and the second stopper 222 may be fixedly connected to the edge of the support platform 21 extending along the width direction of the battery cell 100, that is, the second stopper 222 may stop at one end of the battery cell 100 in the length direction of the battery cell 100 to position the battery cell 100 along the length direction of the battery cell 100.

[0034] Since the length of the battery cell 100 is relatively long, in order to improve the positioning reliability of the battery cell 100, refer to Figure 3 As shown, the positioning assembly 22 may include a plurality of first stops 221, and the plurality of first stops 221 may be spaced apart along the length direction of the battery cell 100 to increase the contact area between the first stops 221 and the edge of the battery cell 100 extending along the length direction, thereby preventing the battery cell 100 from being skewed and improving the positioning reliability of the battery cell 100.

[0035] In order to enable the heating assembly 31 to move along the width direction of the battery cell 100, refer to Figure 1 , Figure 2 as well as Figure 4 As shown, the hot melt module 3 may also include a clamping cylinder 32, a cylinder seat 321 of the clamping cylinder 32 may be fixedly connected to the substrate 1, a piston 322 of the clamping cylinder 32 may move along the width direction of the battery cell 100, and the heating component 31 may be fixedly connected to the end of the piston 322, that is, the piston 322 may drive the heating component 31 to move along the width direction of the battery cell 100. In addition, by controlling the length of the piston 322 extending from the cylinder seat 321 toward the battery cell spacer 101, the clamping force of the heating component 31 on the battery cell 100 may be controlled, so that the hot melt consistency between the battery cell spacer 101 and the side plate 103 is good, reducing the possibility of welding through or incomplete welding.

[0036] In order to fix the cylinder base 321 on the base plate 1, refer to Figure 1 , Figure 3 as well as Figure 4 As shown, a first mounting hole 320 may be provided on the cylinder seat 321, and a second mounting hole 11 for cooperating with the first mounting hole 320 may be provided on the base plate 1. The cylinder seat 321 may be fixedly connected to the base plate 1 by fasteners passing through the first mounting hole 320 and the second mounting hole 11.

[0037] Since the battery cell 100 has multiple models, each model has a different width and / or length. Therefore, in order to improve the versatility of the battery cell spacer side plate hot melt device, reference is made to Figure 4As shown, the first mounting hole 320 can be configured as an oblong hole, and the length direction of the oblong hole can be parallel to the length direction of the battery cell 100, so that the position of the hot melt module 3 can be finely adjusted along the length direction of the battery cell 100. Specifically, the fastener passing through the first mounting hole 320 can be slightly loosened without pulling the fastener out of the first mounting hole 320, and then the pressing cylinder 32 can be moved along the length direction of the battery cell 100 until the hot melt module 3 is adjusted to a desired position, and finally, the fastener is tightened to fix the cylinder seat 321 relative to the substrate 1.

[0038] The length and / or width of the battery cell 100 of different models may vary greatly. In order to further improve the versatility of the hot-melt device for the battery cell spacer side plate, refer to Figure 1 and Figure 3 As shown, a plurality of groups of second mounting holes 11 may be provided on the substrate 1, and the plurality of groups of second mounting holes 11 are arranged at intervals along the length direction and / or width direction of the battery cell 100. When the length and / or width difference between different types of battery cells 100 is small, the position of the hot melt module 3 can be adjusted by moving the fastener in the first mounting hole 320, so that the hot melt module 3 can adapt to different types of battery cells 100 with a small difference in length, and the extension length of the piston 322 can be adjusted to make the hot melt module 3 adapt to different types of battery cells with a small difference in width. When the length and / or width difference between different types of battery cells 100 is large, so that the hot melt module 3 cannot be adapted to the battery cell 100 by the relative movement of the fastener and the first mounting hole 320 and / or the adjustment of the extension length of the piston 322, the position of the hot melt module 3 can be adjusted by installing the cylinder seat 321 to the second mounting hole 11 at different positions.

[0039] In order to control the heating temperature of the heating assembly 31, refer to Figure 1 As shown, the cell spacer side plate hot melt device may further include a control module 4 for controlling the temperature of the heating assembly 31, and the control module 4 may be fixedly connected to the bottom of the substrate 1. By controlling the heating temperature of the heating assembly 31 through the control module 4, the possibility of welding through or incomplete welding can be further avoided, thereby improving welding efficiency and product consistency.

[0040] refer to Figure 4 and Figure 5As shown, the heating component 31 may include a heating copper block 311, a thermocouple 312 and a heating rod 313, wherein the heating copper block 311 is fixedly connected to the piston 322, the heating copper block 311 is used to contact the boss 102 to perform heat melting on the boss 102, the thermocouple 312 can be embedded in the interior of the heating copper block 311, and can be communicated with the control module 4, the thermocouple 312 can measure the temperature of the heating copper block 311, and feed back the measured temperature data to the control module 4, the heating rod 313 can be embedded in the interior of the heating copper block 311, and can be communicated with the control module 4, and the control module 4 can control the heating of the heating copper block 311 by the heating rod 313 according to the temperature data fed back by the thermocouple 312.

[0041] In a specific embodiment of the present disclosure, the control module 4 may be a PLC controller. The control module 4 may be configured to control the heating of the heating copper block 311 by the heating rod 313 according to the temperature measured by the thermocouple 312. Specifically, a preset temperature may be set in the control module 4. When the temperature fed back by the thermocouple 312 is lower than the preset temperature, the control module 4 controls the heating rod 313 to heat the heating copper block 311. When the temperature fed back by the thermocouple 312 is higher than the preset temperature, the control module 4 controls the heating rod 313 to stop heating the heating copper block 311. Through the cooperation between the control module 4 and the thermocouple 312, the temperature of the heating copper block 311 can be accurately controlled.

[0042] In order to prevent the heating copper block 311 from being damaged by excessive temperature of the piston 322, refer to Figure 2 and Figure 4 As shown, a heat insulation plate 33 may be provided between the piston 322 and the heating copper block 311 .

[0043] In addition, in order to prevent the heated copper block 311 from contacting other parts of the battery cell 100, Figure 4 As shown, a heating protrusion 314 may be provided on one side surface of the heating copper block 311 facing the boss 102. When the heating component 31 is close to the battery cell 100, the heating copper block 311 contacts the boss 102 through the heating protrusion 314. Since the heating protrusion 314 has a certain thickness, the one side surface of the heating copper block 311 facing the boss 102 can be separated from the battery cell 100.

[0044] In the specific embodiment of the present disclosure, the working process of the hot-melting device for the cell spacer side plate is as follows: when the control module 4 confirms that the heating copper block 311 has been heated to the preset temperature, the staff will place the cell 100 assembled with the cell spacer 101 and the side plate 103 on the support platform 21 of the cell clamping module 2 for positioning, and confirm that the four heating copper blocks 311 are aligned with the corresponding bosses 102 along the width direction of the cell 100, and then control the piston 322 of the clamping cylinder 32 to extend so that the heating copper block 311 contacts the boss 102, so as to heat and melt the boss 102 until it is fused with the side plate 103. After the hot-melting time is reached, the piston 322 is returned to its position, and the cell 100 is unloaded.
