Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a heat-conducting fixture for heating the tabs of a gel solid soft-pack battery, including a worktable 1 and a heat-conducting component 4. L-shaped plates 2 are fixedly connected to the left and right ends of the worktable 1, and first electric push rods 5 are respectively installed on the inner sides of the vertical ends of the two L-shaped plates 2. Guide strips 3 are symmetrically installed in the middle of the upper part of the worktable 1. The heat-conducting component 4 includes an insulating base 40, an insulating shell 42, and a PTC heating element 403. A U-shaped block 41 is fixedly connected below the insulating base 40, and the PTC heating element 403 is fixedly connected above the insulating base 40. The outer casing 42 has a tab slot 45 in the middle of the left side. The upper left side of the insulating outer casing 42 is equipped with a second electric push rod 46 at the front and rear ends. The telescopic shafts of the two second electric push rods 46 are respectively equipped with clamping plates 47. Thermal grease 404 is provided above the PTC heating element 403. Thermal copper block 402 is attached to the thermal grease 404. This design solves the problems of slow heating speed, which affects production efficiency, and inconvenience in limiting tabs of various widths or lengths, caused by traditional heating methods such as hot air guns and ordinary heating plates.

[0021] In the first embodiment of this utility model: A second threaded square plate 400 is fixedly connected to the middle of the left and right sides of the heat-conducting copper block 402. The two second threaded square plates 400 are respectively connected to the insulating base 40 by second bolts 401. Connecting the two second threaded square plates 400 to the insulating base 40 by second bolts 401 ensures a tight connection between the heat-conducting copper block 402 and the PTC heating element 403 via thermal grease 404, preventing loosening. First threaded square plates 44 are installed at the front and rear ends of the left and right sides of the insulating shell 42. Multiple first threaded square plates 44 are respectively connected to the insulating base 40 by first bolts 43. Connecting multiple first threaded square plates 44 to the insulating base 40 by first bolts 43 facilitates the assembly and disassembly of the insulating shell 42. A first circular hole 48 is provided through the top of the insulating shell 42, and two second circular holes 49 are provided through the rear side of the insulating shell 42. The first circular hole 48 facilitates the passage of a thermocouple, and the two second circular holes 49 facilitate the passage of wires that provide power to the PTC heating element 403. Two heat-conducting components 4 are provided. Two U-shaped blocks 41 are slidably connected to two guide bars 3 respectively. By sliding the two U-shaped blocks 41 to the two guide bars 3 respectively, the position of the heat-conducting components 4 can be adjusted. The telescopic shaft ends of two first electric push rods 5 are fixedly connected to the two U-shaped blocks 41 respectively. Multiple support columns 6 are installed under the worktable 1. By fixing the telescopic shaft ends of the two first electric push rods 5 to the two U-shaped blocks 41 respectively, the position of the heat-conducting components 4 can be adjusted.

[0022] As a second embodiment of this utility model: In use, the positive and negative tabs are first inserted into the two tab slots 45 respectively, so that the two tabs contact the two heat-conducting copper blocks 402. Then, the two second electric push rods 46 are activated, driving multiple clamping plates 47 to move and clamp the two tabs. Then, the battery is fixed in the middle of the workbench 1 by external equipment. At this time, the two first electric push rods 5 are activated, driving the two U-shaped blocks 41 to move synchronously along the two guide bars 3, so that the two tabs contact the two connection ends of the battery respectively. Then, the two PTC heating elements 403 are activated, so that heat is transferred to the two heat-conducting copper blocks 402 through the thermal grease 404, and then transferred to the two tabs to meet the heating work of the two tabs. Temperature can be observed and the power can be adjusted by the cooperation of thermocouples connected to the heat-conducting copper blocks 402 to ensure constant temperature. This is a mature existing technology and will not be described in detail here.
