Description

Technical Field

[0001] This application relates to the field of product processing equipment, specifically a detachable and reusable cleaning bracket, which is mainly used for loading, cleaning, and turnover of small mobile phone decorative parts after they have been processed and unloaded by an automated machine tool. Background Technology

[0002] Existing cleaning brackets for mobile phone decorative items are injection molded from POK (polyketone) material. Their structural components include two first frame borders, two second frame borders, and multiple loading beams. Each of the four frame borders has three limiting blocks for easy stacking and improved stacking stability. Simultaneously, all four frame borders are perforated to reduce unit weight and facilitate the exchange and flow of cleaning fluid during the cleaning process. Different loading beams are used depending on the size of the product model. However, in existing technology, the loading beams of the cleaning bracket lack sufficient rigidity, making them prone to deformation and easy to fall off during product cleaning and transportation. The small size of the loading beams and the use of single-point mating result in structural instability, making them prone to offset in the extension direction of the first frame, which is detrimental to stacking. Furthermore, existing cleaning brackets for decorative items have low adaptability, requiring the replacement of corresponding loading beams for different product models, thus increasing mold, equipment, and material costs. The process turntable increases the workload of employees, reduces work efficiency, and indirectly increases labor costs. Moreover, due to the unstable structure of the loading beam, small decorative items are prone to falling off the cleaning bracket during cleaning and transfer, causing product damage. Utility Model Content

[0003] This application provides a detachable and reusable cleaning bracket, which overcomes the structural instability caused by using loading beams to divide the existing cleaning bracket, and the high cost of cleaning different decorative items.

[0004] To achieve the above objectives, this application provides a detachable and reusable cleaning bracket, comprising:

[0005] The detachable bracket body is assembled from a first frame, a second frame, and at least one mounting plate via a snap-fit ​​structure.

[0006] Multiple soft rubber pieces can be detachably installed on the mounting plate, and the position of the soft rubber pieces is adjustable;

[0007] The mounting plate is fixed to the first frame by a two-way limiting structure, which includes a straight arm buckle and corresponding mating holes to constrain the horizontal freedom of the mounting plate.

[0008] In one feasible embodiment, the soft rubber granule is connected to the mounting plate by an elastic snap-fit ​​structure, which includes a mounting hole on the mounting plate and an elastic protrusion of the soft rubber granule. The elastic protrusion contracts when pressed to enter or exit the mounting hole and expands in its natural state to fix the soft rubber granule.

[0009] In one feasible embodiment, the top of the soft rubber granule is a support portion for carrying the cleaning component, and a guide groove is provided on the top surface of the support portion.

[0010] In one feasible embodiment, the soft granules are made of a high-temperature resistant thermoplastic elastomer material.

[0011] In one feasible embodiment, the mounting plate has symmetrical positioning bosses on both sides, and the inner side of the first frame has a guide groove that matches the positioning bosses, which is used to guide the movement path of the mounting plate and limit the vertical displacement when the mounting plate is inserted.

[0012] In one feasible embodiment, a complementary stacking limiting structure is provided on the first and second frames. The complementary stacking limiting structure includes a set of mutually cooperating ribs and grooves. When multiple brackets are stacked, stable positioning is achieved by the interlocking of the ribs and grooves.

[0013] In one feasible embodiment, the mounting holes on the mounting plate are distributed in a matrix at a preset spacing, and the center distance between adjacent mounting holes is an integer multiple of the standard size of the cleaning part, so as to achieve precise adaptation to the size of small parts.

[0014] In one feasible embodiment, the sidewalls of the first and second frames are provided with strip-shaped hollow areas, thereby reducing the overall weight of the bracket and allowing the cleaning fluid to be exchanged and circulated along the hollow areas during the cleaning process.

[0015] In one feasible embodiment, the surface of the mounting plate is provided with size markings that correspond one-to-one with the standard dimensions of the cleaning parts, so as to achieve accurate positioning for unloading small cleaning parts.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] High versatility: The original loading beam is replaced with a mounting plate + soft rubber granules. The position of the soft rubber granules can be changed to adapt to the size of different cleaning parts, which improves the versatility of the bracket.

[0018] Stable structure: The mounting plate fits together to improve the stability of the cleaning bracket, thereby reducing the rate of falling off cleaning components during cleaning and transfer.

[0019] Low operating cost: No need to change the loading beam for different product models, reducing mold opening costs, equipment costs, and material costs. At the same time, it reduces the number of process turntable operations, improving work efficiency and reducing labor costs.

[0020] Avoid three types of product damage: The stable structure effectively prevents damage caused by the falling of cleaning components during cleaning and transfer. Attached Figure Description

[0026] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0027] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0028] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] The following is combined Figure 1 , Figure 2 and Figure 3 This application describes a detachable and reusable cleaning bracket provided in an embodiment.

[0030] like Figure 1 As shown, this embodiment provides a cleaning bracket, including a first frame 1, a second frame 2, a mounting plate 3, and soft rubber particles 4. Both the first frame 1 and the second frame 2 are elongated structures injection molded from POM (polyoxymethylene) material. The sidewalls of the first frame 1 and the second frame 2 are provided with strip-shaped hollow areas, which are elongated through holes parallel to the flow direction of the cleaning fluid. The overall length of the hollow areas is 80% of the total length of the frames, and the volume of the overall hollow areas accounts for 38% of the volume of the cleaning bracket body.

[0031] Mounting plate 3 is made of glass fiber reinforced nylon material with a thickness of 4mm. Mounting holes 31 are arranged in a 5mm × 5mm matrix on its surface, with the center distance between adjacent mounting holes controlled within ±0.05mm. Both ends of mounting plate 3 are equipped with straight-arm buckles 32, the ends of which have a gradually narrowing wedge-shaped chamfer. In this embodiment, the angle of the wedge-shaped chamfer is 15°. After the wedge-shaped chamfer is inserted into the limiting hole of the first frame 1, bidirectional locking is achieved through the horizontal reverse force generated by the elastic deformation of the buckle.

[0032] See Figure 2 The soft rubber granule 4 is injection molded from high-temperature resistant TPU material. In this embodiment, the bottom of the soft rubber granule 4 is provided with an elastic protrusion 41 with a diameter of 3.2mm. Correspondingly, the diameter of the mounting hole 31 is 3.0mm, and the interference fit between the mounting hole 31 and the soft rubber granule 4 is 0.2mm. The top of the soft rubber granule is a support part 42 for supporting the cleaning parts, and a guide groove 43 is provided on the top surface of the support part 42.

[0033] It should be noted that after the soft rubber granules are continuously soaked in hot water at 90°C for 24 hours, they need to maintain a certain hardness and the tensile strength should not decrease too much. In this embodiment, the selected soft rubber granule material is TPU75A, which has a hardness retention rate of 92% and a tensile strength decay rate of 3.8% after being continuously soaked in hot water at 90°C for 24 hours.

[0034] Assembly process:

[0035] According to the size of the cleaning part (such as the standard specification of 5mm×5mm), select the corresponding mounting hole 31 position on the mounting plate 3, press the soft rubber granules 4 vertically into place, and fix them by the interference fit between the elastic protrusion 41 and the mounting hole 31.

[0036] Align the straight arm buckle 32 of the mounting plate 3 with the limiting hole of the first frame 1, and push it along the guide rib 12 until the positioning boss and the guide groove are fully engaged. In this embodiment, the cross section of the guide rib is a trapezoidal cross section with a top width of 2.5mm and a bottom width of 3.0mm.

[0037] The second frame 2 is assembled with the mounting plate 3 in the same way to form a complete bracket body. Multiple mounting plates can be installed on the complete bracket body.

[0038] The following describes the workflow of the cleaning bracket provided in this application, in order to better understand the technical solution provided in this application.

[0039] During the cleaning process, the cleaning bracket provided in this embodiment is immersed in an alkaline cleaning solution (pH=10) at 80°C and circulated at a flow rate of 2 m / s. Due to the strip-shaped hollow area and the directional openings in the strip-shaped hollow area, the weight of the cleaning bracket is reduced by 32%, while the cleaning solution exchange efficiency is increased by 45%. The cleaning solution can clean the cleaning components on each mounting plate 3, and the guide grooves 43 of the soft rubber particles 4 increase the removal rate of residual particles on the surface of the cleaning components to 99.6%, with no small parts falling off.

[0040] In the above embodiments, the cleaning bracket provided in this application replaces the original loading beam with a mounting plate and soft rubber granules. The position of the soft rubber granules can be changed to adapt to the size of different cleaning parts. Each mounting plate has 65 mounting holes, and when the bracket is fully installed on the mounting plate, there are a total of 260 mounting holes, thus accommodating cleaning parts of different sizes. Simultaneously, the dual-point engagement of the mounting plate improves the stability of the cleaning bracket, thereby reducing the drop rate of cleaning parts during cleaning and transfer, and lowering the three-damage defect rate from the original 5% to 0%.

[0041] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
