Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing equipment, and in particular to a battery box cover packaging positioning fixture structure. Background Technology

[0002] In the production and transportation of battery packs, the battery box cover is a key structural component, and its packaging protection is of utmost importance. A good packaging plan must ensure that the box cover is not damaged by bumps, scratches, deformation, etc. during storage and transportation, so as to maintain its structural integrity and surface quality, meet the subsequent assembly requirements, and ensure the overall performance of the battery pack.

[0003] However, the packaging methods widely used in existing technologies have significant drawbacks, such as... Figure 7 As shown, this method requires placing the first battery box cover 1 with its opening facing upwards, laying pearl cotton 5 on top of it, then inverting the second battery box cover 2 with its opening facing downwards onto the pearl cotton 5. Nylon strapping is then used to secure the mounting flanges of the two covers, and paper corner protectors 6 are wrapped around the four corners of the assembly. Finally, stretch film is used for external protection. This traditional method has revealed a series of problems in practice: First, it heavily relies on disposable materials such as pearl cotton and paper corner protectors, which are discarded after unpacking and cannot be recycled, resulting in continuous material waste and rising packaging costs. Second, this packaging structure has inherent weaknesses, especially the thin walls and lack of effective support at the four corners of the assembly, making it extremely susceptible to deformation under pressure during transportation under stretch film protection. The defect rate can be as high as 70%, and deformed covers often require rework and reshaping before shipment, wasting manpower and resources and severely impacting delivery efficiency. Furthermore, the nylon strapping operation is cumbersome, significantly slowing down the overall packaging process and becoming a bottleneck for improving production efficiency.

[0004] Therefore, how to develop a battery box cover packaging positioning tooling structure that can effectively replace disposable consumables, significantly enhance the structural rigidity of the box cover assembly, simplify the fixing process and improve packaging efficiency, and at the same time realize the recyclability of positioning components to reduce costs has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a battery box cover packaging positioning fixture structure that can effectively replace disposable consumables, significantly enhance the structural rigidity of the box cover assembly, simplify the fixing process and improve packaging efficiency, and at the same time, realize the recyclability of the positioning components to reduce costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a battery box cover packaging positioning fixture structure, including a first battery box cover, a second battery box cover, a first positioning block, a second positioning block, and a stretch film. The first battery box cover is placed on a work platform with its opening facing upward. Four second positioning blocks are respectively engaged at the four corners of the edge of the opening end of the first battery box cover. At least two first positioning blocks are engaged on opposite sides of the edge of the opening of the first battery box cover, and the first positioning blocks are arranged in pairs. The second battery box cover has its opening facing downward and is fastened to the top of the first battery box cover by the first positioning blocks and the second positioning blocks. The stretch film is circumferentially wrapped and fixedly assembled with the first battery box cover, the second battery box cover, the first positioning block, and the second positioning block.

[0008] Preferably, the opening end of the first battery box cover is provided with a first mounting flange, and a plurality of first connection holes are equally spaced on the first mounting flange.

[0009] Preferably, the opening end of the second battery box cover is provided with a second mounting flange, and the second mounting flange is provided with a plurality of second connecting holes that match the first connecting holes at equal intervals.

[0010] Preferably, the first positioning block includes a square pad, a first positioning buckle, and a first positioning pin. A plurality of first positioning buckles are equally spaced on one long side of the square pad. The square pad is sandwiched between the first mounting flange and the second mounting flange. A plurality of first positioning pins are symmetrically arranged on both sides of the square pad. The first positioning pins are respectively engaged with the first connecting hole and the second connecting hole. The side of the first positioning buckle near the square pad abuts against the outer edge of the first mounting flange and the second mounting flange.

[0011] Preferably, the square pad is provided with first mesh reinforcing ribs on both the upper and lower sides.

[0012] Preferably, the second positioning block includes an L-shaped pad, a triangular wedge pad, a second positioning buckle, and a second positioning pin. Multiple second positioning buckles are evenly spaced along the outer edge of the L-shaped pad. A triangular wedge pad is fixedly connected to the inner edge of the L-shaped pad. The L-shaped pad is sandwiched between the first mounting flange and the second mounting flange. Multiple second positioning pins are symmetrically arranged on the upper and lower sides of the L-shaped pad. The second positioning pins engage with the first connecting hole and the second connecting hole respectively. The side of the second positioning buckle closest to the L-shaped pad abuts against the outer edges of the first mounting flange and the second mounting flange.

[0013] Preferably, the L-shaped pad and the triangular wedge-shaped pad are provided with second grid reinforcing ribs on both the upper and lower sides.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] 1) This utility model uses reusable nylon material for the first and second positioning blocks, which completely replace the disposable pearl cotton lining and paper corner protectors in the prior art. These positioning blocks have the characteristics of high strength, wear resistance and good toughness. They can withstand transportation pressure and withstand multiple disassembly and recycling, which fundamentally avoids the continuous consumption and waste of a large number of disposable consumables in traditional packaging, effectively reduces material costs and waste, and conforms to the concept of environmentally friendly production.

[0016] 2) In this utility model, the second positioning blocks are snapped into the four corners of the opening edge of the first battery box cover, and the first positioning blocks are set in pairs on the opposite sides. These positioning blocks not only improve their compressive strength through the first and second mesh reinforcing ribs, but more importantly, they are firmly clamped and snapped between the mounting flanges of the two box covers (through the cooperation of positioning pins and connecting holes, and the abutment of positioning buckles with the flange edges), forming a rigid support frame. This structural design particularly strengthens the weakest four corner areas in traditional packaging, effectively disperses and bears external pressure, and effectively avoids the deformation problem caused by insufficient support at the four corners in the prior art.

[0017] 3) This utility model eliminates the cumbersome steps of laying pearl cotton, wrapping paper corner protectors, and binding nylon straps in the prior art. The positioning block can be quickly and accurately installed on the box cover and the two box covers can be fastened, positioned and fixed by a simple snap-fit ​​method (the positioning pin is inserted into the connecting hole and the positioning buckle abuts against the edge of the flange). The entire assembly process is clear and easy to operate, which significantly shortens the packaging time of a single product. Afterwards, only circumferential wrapping with stretch film is needed to complete the packaging, which greatly improves the efficiency of the overall packaging operation. Attached Figure Description

[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] like Figure 1-6 As shown, a battery box cover packaging positioning fixture structure includes a first battery box cover 1, a second battery box cover 2, a first positioning block 3, a second positioning block 4, and a stretch film. The first battery box cover 1 is placed on a work platform with its opening facing upwards. Four second positioning blocks 4 are respectively engaged at the four corners of the edge of the opening end of the first battery box cover 1. At least two first positioning blocks 3 are engaged on opposite sides of the edge of the opening of the first battery box cover 1, and the first positioning blocks 3 are arranged in pairs. The second battery box cover 2 has its opening facing downwards and is fastened to the top of the first battery box cover 1 by the first positioning blocks 3 and the second positioning blocks 4. The stretch film is circumferentially wrapped and fixedly assembled with the first battery box cover 1, the second battery box cover 2, the first positioning block 3, and the second positioning block 4.

[0029] Specifically, the stretch film is made of linear low-density polyethylene, which has good puncture resistance and tensile properties. It is used to protect the product surface from scratches during packaging and to firmly fix the assembled product components.

[0030] Specifically, the first positioning block 3 and the second positioning block 4 are both made of nylon material. Nylon material has high strength, good wear resistance and toughness, can withstand greater pressure and withstand repeated use, ensuring that the positioning blocks maintain structural stability during packaging and transportation, thereby effectively protecting the battery box cover.

[0031] Specifically, users can flexibly set multiple pairs of first positioning blocks 3 on the long side and short side of the opening edge of the first battery box cover 1 according to actual packaging needs; or set them on both the long side and short side at the same time, so as to adapt to battery box cover packaging of different sizes or protection requirements.

[0032] Specifically, the first battery box cover 1 has a first mounting flange 11 at its open end, and the first mounting flange 11 has a plurality of first connection holes 12 at equal intervals.

[0033] Specifically, the second battery box cover 2 has a second mounting flange 21 at its open end, and the second mounting flange 21 has a plurality of second connecting holes 22 that match the first connecting hole 12 at equal intervals.

[0034] Specifically, the first positioning block 3 includes a square pad 31, a first positioning buckle 32, and a first positioning pin 33. Multiple first positioning buckles 32 are evenly spaced on one long side of the square pad 31. The square pad 31 is sandwiched between the first mounting flange 11 and the second mounting flange 21. Multiple first positioning pins 33 are symmetrically arranged on both sides of the square pad 31. The first positioning pins 33 are respectively engaged with the first connecting hole 12 and the second connecting hole 22. The side of the first positioning buckle 32 near the square pad 31 abuts against the outer edge of the first mounting flange 11 and the second mounting flange 21.

[0035] Specifically, the square pad 31 is provided with first grid reinforcing ribs 34 on both the upper and lower sides.

[0036] Specifically, the first positioning block 3, which is sandwiched between the first battery box cover 1 and the second battery box cover 2, has first positioning pins 33 symmetrically arranged on the upper and lower sides of the square pad 31. These pins are respectively engaged in the first connecting hole 12 of the first mounting flange 11 and the second connecting hole 22 of the second mounting flange 21 to form a snap-fit ​​fit. This connection method provides reliable positioning and connection stability when the first battery box cover 1 and the second battery box cover 2 are snapped together, effectively preventing relative displacement between the two during subsequent packaging or transportation.

[0037] Specifically, the first positioning buckle 32 set on the first positioning block 3 abuts against the outer edges of the first mounting flange 11 and the second mounting flange 21 on the side facing the body of the square pad 31. After the buckle is assembled, this abutting structure can restrict the relative movement of the first battery box cover 1 and the second battery box cover 2 in the horizontal direction, further enhancing the stability of the connection between the two and effectively preventing the occurrence of relative displacement.

[0038] Specifically, the second positioning block 4 includes an L-shaped pad 41, a triangular wedge-shaped pad 42, a second positioning buckle 43, and a second positioning pin 44. Multiple second positioning buckles 43 are evenly spaced on the outer edge of the L-shaped pad 41, and a triangular wedge-shaped pad 42 is fixedly connected to the inner edge of the L-shaped pad 41. The L-shaped pad 41 is sandwiched between the first mounting flange 11 and the second mounting flange 21. Multiple second positioning pins 44 are symmetrically arranged on the upper and lower sides of the L-shaped pad 41. The second positioning pins 44 are respectively engaged with the first connecting hole 12 and the second connecting hole 22. The side of the second positioning buckle 43 near the L-shaped pad 41 abuts against the outer edge of the first mounting flange 11 and the second mounting flange 21.

[0039] Specifically, the L-shaped pad 41 and the triangular wedge-shaped pad 42 are provided with second grid reinforcing ribs 45 on both the upper and lower sides.

[0040] Specifically, the second positioning block 4, which is sandwiched between the first battery box cover 1 and the second battery box cover 2, has second positioning pins 44 symmetrically arranged on the upper and lower sides of the L-shaped pad 41. These pins are respectively engaged in the first connecting hole 12 of the first mounting flange 11 and the second connecting hole 22 of the second mounting flange 21 to form a snap-fit ​​fit. This connection method also provides reliable positioning and connection stability during snap-fit ​​assembly, effectively preventing relative displacement between the two covers.

[0041] Specifically, the second positioning buckle 43, which is set on the second positioning block 4, abuts against the outer edges of the first mounting flange 11 and the second mounting flange 21 on the side facing the body of the L-shaped pad 41. This abutting structure can restrict the relative movement of the two battery box covers in the horizontal direction, further enhancing the stability of the connection between the two and effectively preventing relative displacement.

[0042] Specifically, the first grid reinforcing rib 34 and the second grid reinforcing rib 45 can improve the compressive strength while reducing the material usage of the square pad 31, L-shaped pad 41 and triangular wedge pad 42. In addition, the first positioning block 3 and the second positioning block 4 can be recycled, which can effectively reduce the production material cost.

[0043] Specifically, the triangular wedge-shaped pad 42 can further improve the structural stability of the L-shaped pad 41.

[0044] The usage process of this utility model is as follows:

[0045] First, place the first battery box cover with its opening facing upwards on the work platform to ensure its stability. Then, snap a second positioning block at each of the four corners of the edge of the opening of the first battery box cover. Next, based on the actual size of the battery box cover to be packaged and the protection requirements, select at least one pair of first positioning blocks to install on opposite sides of the edge of the opening of the first battery box cover (which can be the long side, the short side, or both the long and short sides). These first positioning blocks are also fixed to the first mounting flange by snapping.

[0046] Next, take the second battery box cover, with its opening facing down, and accurately align and fasten it onto the top of the first battery box cover where the first positioning block and the second positioning block have been placed. During this fastening process, the first positioning pin and the second positioning pin, which are set on the upper and lower sides of the first positioning block and the second positioning block, will be inserted into the first connecting hole on the first mounting flange of the first battery box cover and the second connecting hole on the second mounting flange of the second battery box cover, forming a reliable snap-fit ​​engagement. This achieves precise positioning and initial connection and fixation of the two covers in the vertical direction. At the same time, the first positioning buckle on the first positioning block and the second positioning buckle on the second positioning block will tightly abut against the outer edges of the first mounting flange and the second mounting flange, respectively, on the sides facing the positioning block body. This effectively restricts the relative movement of the two covers in the horizontal direction, further enhancing the stability of the connection and preventing relative displacement.

[0047] Then, after ensuring that the first battery box cover and the second battery box cover are firmly fastened together by the first positioning block and the second positioning block, the assembled whole structure is wrapped circumferentially with stretch film. The wrapping operation must ensure that the stretch film tightly wraps the entire component. Utilizing the excellent puncture resistance and tensile properties of the material, the surface of the battery box cover is protected from scratches during the packaging process, and the stretch film's tensile and retractive force firmly fixes the entire assembly into a tight whole.

[0048] Finally, after the stretch film is wrapped and secured, the final packaged product components are formed.
