Description

Technical Field

[0001] The utility model belongs to the technical field of lithium ion battery manufacturing, and in particular relates to a test fixture structure. Background Art

[0002] In the lithium-ion battery manufacturing industry, one type of formation equipment is FCT equipment. FCT functional test fixtures are used to test product functionality. FCT functional test fixtures primarily test lithium-ion battery PCBAs (printed circuit boards). PCBAs undergo various performance tests using different fixtures. FCT test fixtures primarily test the PCBA after power-on, covering voltage, current, power, power factor, frequency, duty cycle, brightness and color, character recognition, voice recognition, temperature measurement, pressure measurement, and motion control.

[0003] In the FCT functional test fixture, the formation cables are installed in the cable trays on both sides of the fixture; they move with the fixture layers. However, during the battery cell formation process, the fixture layers remain at a constant temperature of 80°C. Because the formation cables are located in close proximity to the fixture layers, they can soften, deform, and collapse significantly under prolonged heat conduction and radiation. This collapsed portion of the cable becomes trapped between the cable bracket and the cable connector. As the cable moves with the fixture layers, it is squeezed by the bracket and breaks, rendering the entire fixture unusable. Utility Model Content

[0033] The following is combined with Figures 1 to 5 The present invention is further described in detail, but is not intended to limit the present invention.

[0034] like Figure 1 As shown, in one embodiment of the present invention, the test fixture structure includes a frame 1, a motion drive mechanism 2, a wiring harness 4, a movable support body 5 and at least two clamps 3; the motion drive mechanism 2 is connected to the frame 1; and the movable end of the motion drive mechanism 2 is connected to all the clamps 3 so that all the clamps 3 move in the frame 1; a clamping gap 301 is provided between two adjacent clamps 3; one end of the wiring harness 4 is connected to one end of the movable support body 5, and is electrically connected to the clamp 3 (that is, one end of the wiring harness 4 is fixed or snap-fitted to one end of the movable support body 5, and one end of the wiring harness 4 is electrically connected to the clamp 3); and one end of the movable support body 5 is connected to the clamp 3.

[0035] The technical solution of the present invention assembles one end of the wiring harness and one end of the movable support body to the same splint 3 at the same time, so that when the wiring harness 4 follows the movement of the splint 3, the movable support body 5 can support the wiring harness 4, so as to avoid the temperature carried by the splint 3 itself causing the wiring harness 4 to be softened and deformed and then be squeezed and broken between the splint 3 and the frame 1, thereby improving the protection performance of the wiring harness 4 and ensuring that the length of the wiring harness 4 during use is sufficient for the normal use of the entire equipment, so as to improve the fluency and efficiency of use.

[0036] Specifically, in some embodiments, Figure 1 As shown, the motion drive mechanism 2 includes a drive motor 21 and a rotating shaft 22. The drive motor 21 is mounted on the frame 1 and is in driving connection with the rotating shaft 22. All of the clamping plates 3 are connected to the surface of the rotating shaft 22. The rotating shaft 22 is a rotating screw. Driven by the drive motor 21, all of the clamping plates 3 perform a reciprocating lateral motion within the frame 1, achieving operational flexibility for testing.

[0037] Specifically, in some embodiments, Figure 1As shown, there are at least three clamping plates 3 arranged side by side; one end of the movable support 5 is connected to the side end of the outermost clamping plate 3; the other end of the movable support 5 is connected to the frame 1. In other words, by assembling the movable support 5 and the wire harness 4 at the same end to the outermost clamping plate 3, the phenomenon of the middle clamping plate 3 effectively clamping the wire harness 4 can be effectively prevented, and the wire harness 4 can be kept as long as possible, ensuring that the length of the wire harness 4 is sufficient for normal use of the entire device during use.

[0038] Specifically, in some embodiments, Figures 1 to 3 As shown, a mounting block 6 is provided at the side end of the clamping plate 3, and a mounting gap 8 is defined between the mounting block 6 and the movable support 5. One end of the wiring harness 4 is connected to the mounting gap 8, and the wiring harness 4 itself at least partially abuts the surface of the movable support 5. In other words, by clamping the wiring harness 4 between the mounting block 6 and the movable support 5, and then supporting at least partially the middle section of the wiring harness 4 against the surface of the movable support 5, even if the wiring harness 4 becomes soft during movement, it will not collapse or fall off the clamping plate 3, thereby ensuring the safety of the wiring harness 4 and extending its service life.

[0039] In some embodiments, the mounting block 6 includes an obliquely arranged horizontal block 601 and a vertical block 602. The mounting gap 8 is formed between the horizontal block 601, the vertical block 602, and the movable support 5. The side end of the vertical block 602 abuts against the movable support 5. This structure can improve the clamping stability of the wiring harness 4 and ensure the stability of the overall assembly.

[0040] Specifically, in some embodiments, Figure 1 and 2 As shown, the test fixture structure also includes a connector 7; the two ends of the connector 7 are connected to the mounting block 6 and the movable support body 5 respectively. Figure 2 and 3 As shown in FIG4 , the mounting block 6 is provided with at least one first mounting hole 61; the connector 7 is provided with a second mounting hole 71 corresponding to the first mounting hole 61; that is, the connector 7 is assembled with the first mounting hole 61 and the second mounting hole 71 by bolts or screws, and is detachably connected to the mounting block 6; thereby ensuring the stability of the assembly and the convenience of disassembly and installation. Figure 2 and 4As shown in Figure 5, the connector 7 is further provided with at least one third mounting hole 72; the movable support body 5 is provided with a fourth mounting hole 521 corresponding to the third mounting hole 72; that is, the connector 7 is assembled with the third mounting hole 72 and the fourth mounting hole 521 by bolts or screws, and is detachably connected to the movable support body 5; thereby ensuring the stability of the assembly and the convenience of disassembly and installation. Furthermore, the connector 7 is a quadrilateral connector. This structure can reduce the production and processing costs of the connector 7, and can also ensure the convenience and flexibility of assembly. Further, as Figure 4 As shown, the third mounting holes 72 include at least two first through holes 721 and at least two second through holes 722; all first through holes 721 are arranged in a first straight line (vertically); all second through holes 722 are arranged in a second straight line (horizontally); and the first and second straight lines intersect. Furthermore, the first and second straight lines are perpendicular to each other. Positioning and assembling the first and second through holes 721 and 722 from different directions further improves the assembly stability between the movable support 5 and the connector 7.

[0041] Specifically, in some embodiments, Figure 1 and 5 As shown, the movable support 5 includes at least two rotating bodies 51 and at least one connecting block 52. Two adjacent rotating bodies 51 are connected in a rotational manner. The connecting block 52 is connected to the outermost rotating body 51. One end of the wiring harness 4 is connected to the connecting block 52. The connecting block 52 forms the mounting gap 8 with the mounting block 6 and the connector 7. The fourth mounting hole 521 is provided in the connecting block 52. In other words, the rotation of the rotating bodies 51 allows the rotating bodies 51 to support and drive the wiring harness 4 during the lateral movement of the clamping plate 3, thereby preventing the wiring harness from collapsing and improving safety and stability.

[0042] Specifically, in some embodiments, Figure 5 As shown, the rotating body 51 includes at least two supporting side blocks 511 arranged side by side and a supporting transverse block 512 connected between two adjacent supporting side blocks 511. A rotating post 5114 is provided at one end of each supporting side block 511, and a rotating hole 5115 corresponding to the rotating post 5114 is provided at the other end of each supporting side block 511. In other words, the rotating posts 5114 of one adjacent supporting side block 5114 are integrally assembled with the rotating holes 5115 of the other adjacent supporting side block 5115 to form a rotating structure, thereby enhancing flexibility.

[0043] Wherein, in some embodiments, Figure 5As shown, the supporting side block 511 includes a first connecting segment 5112, a main segment 5111 and a second connecting segment 5113 connected in sequence; and the projection of the first connecting segment 5112 toward the main segment 5111 and the projection of the second connecting segment 5113 toward the main segment 5111 at most partially overlap; that is, the first connecting segment 5112, the main segment 5111 and the second connecting segment 5113 form a "ㄅ" structure; thereby ensuring the flexibility of rotation.

[0044] Specifically, in some embodiments, Figure 5 As shown, the surface of the supporting transverse block 512 is provided with a retaining groove 5121 corresponding to the wiring harness 4. In other words, after one end of the wiring harness 4 is fixed by the connecting block 52, the connector 7 and the mounting block 6, at least part of the wiring harness 4 is retained and assembled in the retaining groove 5121 to prevent the wiring harness 4 from collapsing or excessive swinging and bending.
