[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-4 As shown in the figure, the detachable dispensing fixture for CCS wiring harness in this embodiment is essentially a detachable dispensing fixture for dispensing CCS wiring harness in the existing CCS assembly. By setting up the structure, the traditional method of manual dispensing is eliminated, resulting in higher dispensing accuracy.

[0025] This embodiment includes an injection-molded isolation plate 2, on which an assembly groove 1 is formed. The assembly groove 1 includes a wiring groove 8 in which wire harnesses 3 are arranged internally. The branch lines of the wire harnesses 3 are distributed outward through the branching grooves 9 opened on the assembly groove 1. A clamping unit 6 is detachably connected to the gap outside the wiring groove 8. On the other side of the clamping unit 6, a wire harness dispensing fixture 5 is provided that is detachably connected to the injection-molded isolation plate 2.

[0026] Both sides of the assembly slot 1 are provided with wiring slots 8, which extend in the same direction along the length of the assembly slot 1. That is, the wiring slots 8 are formed according to the extension path of the assembly slot 1, and the wire bundles 3 in the wiring slots 8 are arranged according to the path of the wiring slots 8. Cable ties 7 are provided around the wiring slots 8, which is existing technology, to further secure the wire bundles 3 in the wiring slots 8 and provide a stable connection. Each wiring slot 8 has a branch slot 9 on its outer side wall, which helps to improve assembly consistency and ensure accurate connection.

[0027] There are multiple branch slots 9, and each branch slot 9 has a branch line of wire harness 3 arranged in it to ensure the accurate routing of the branch line of wire harness 3.

[0028] Each branch of the wire harness 3 corresponds to a clip 4. Clip 4 is existing technology, and the fastening and communication connection between clip 4 and wire harness 3 is also existing technology. After the wire harness 3 is glued, clip 4 is snapped into the assembly slot 1 through the snap-fit ​​structure 10. That is to say, clip 4 is not assembled before the wire harness 3 is glued. In terms of process flow, the glue dispensing of wire harness 3 takes precedence over the assembly of clip 4. Based on this, it can be understood that when the wire harness glue dispensing fixture 5 is connected to the clamping unit, the clip 4 at that point is not assembled, and the wire harness glue dispensing fixture 5 occupies the position of the clip 4 to be assembled at that point.

[0029] The wire harness dispensing fixture 5 includes a fixture body 13 and a dispensing avoidance area 14 formed on the fixture body 13. The dispensing avoidance area 14 is formed in such a way that the branch lines of the wire harness 3 are exposed. That is to say, the dispensing avoidance area 14 is the position where the glue needs to be dispensed. By using the dispensing avoidance area 14 to circle the position where the glue needs to be dispensed, it is beneficial to standardize and determine the dispensing area, and the glue can be accurately applied to the required position, fundamentally eliminating the need for manual prediction. Furthermore, the dispensing avoidance area 14 exposes the branch lines of the wire harness 3, which facilitates the dispensing process. It should be noted that the shape of the dispensing avoidance area 14 can be processed according to actual needs.

[0030] Preferably, a connecting protrusion 12 is formed on the lower surface of the tooling body 13. Correspondingly, a connecting hole 11 is provided on the injection molding isolation plate 2 at the position of the branch line dispensing area of ​​the wire harness 3 to match and connect with the connecting protrusion 12, so as to achieve the purpose of making the wire harness dispensing tooling 5 detachable.

[0031] The clamping unit 6 is detachably connected in the gap between the wire harness dispensing fixture 5 and the side wiring groove 8. It is used to prevent the components from shifting due to vibration, impact and other factors during equipment operation. The clamping unit 6 has a first clamping leg 15 and a second clamping leg 16 with their ends connected and their extensions spaced apart from each other. The clamping clearance area 17 is between the first clamping leg 15 and the second clamping leg 16. The clamping clearance area 17 clamps the injection molding isolation plate 2, i.e. the branch line of the wire harness 3, thereby preventing the branch line of the wire harness 3 from moving or shifting during the dispensing process.

[0032] This application discloses a detachable wire harness dispensing fixture for CCS wire harnesses in power batteries, which has the following advantages:

[0033] (1) Wide range of applications: It can be applied to dispensing operations for products of various specifications and shapes;

[0034] (2) High dispensing accuracy: Through precise positioning and clamping, the product is ensured to be in a stable position during the dispensing process;

[0035] (3) Easy to operate: The adjustment mechanism is reasonably designed, which makes it easy for operators to quickly adjust the fixture;

[0036] (4) Improved efficiency: The dispensing process reduces manual intervention and improves production efficiency.

[0037] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
