Abstract
Description
Technical Field
[0001] This utility model relates to the field of jig manufacturing technology, specifically a stacking jig. Background Technology
[0002] In the field of precision assembly of electronic products, the accurate lamination of multilayer thin-film materials is a key process to ensure product quality. Traditional lamination fixtures generally suffer from the following technical defects:
[0003] 1. Interference problem in positioning structure: Conventional right-angle positioning blocks adopt a symmetrical layout. When pressing different material layers continuously, the right-angle positioning blocks that unfold one after another are prone to spatial interference, making it impossible to achieve continuous positioning of multi-level materials.
[0004] 2. Defects in datum stability: Existing right-angle positioning mechanisms mostly adopt a two-point positioning method, which is easily affected by material deformation in actual pressing operations, making it difficult to establish a reliable planar datum, resulting in cumulative tolerances in laminated materials.
[0005] 3. Spatial layout limitations: Traditional flipping mechanisms are directly mounted on the substrate surface, which increases the overall thickness of the fixture by about 35%-40%, affecting the flatness of material placement and limiting the ability to operate in confined spaces. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a stacking fixture suitable for the pressing and positioning of multi-layer thin film materials, which solves the spatial interference problem of traditional symmetrical right-angle positioning blocks when pressing multiple material layers continuously, and realizes the formation of horizontal placement references for different material layers; and constructs a right-angle positioning reference for the initial horizontal placement of the material layers.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A stacking fixture includes a fixture base plate, a first positioning right-angle block, and a second positioning right-angle block. A flipping mechanism is provided between the first and second positioning right-angle blocks and the fixture base plate. The first and second positioning right-angle blocks are pivotally connected to opposite sides of the fixture base plate through the flipping mechanism, and the first and second positioning right-angle blocks are staggered in the length direction of the fixture base plate. The upper surface of the fixture base plate is provided with a right-angle positioning reference composed of at least three positioning posts.
[0009] Furthermore, the upper edge of the fixture substrate is provided with a mounting groove for the flipping mechanism to be disposed therein.
[0010] Furthermore, the upper edge of the fixture base plate is provided with positioning points for positioning during the pressing of right-angle blocks.
[0011] Furthermore, the upper edge of the fixture substrate is provided with small magnets for magnetic attraction during the pressing of right-angle blocks.
[0012] Furthermore, the fixture substrate is made of graphite material.
[0013] Furthermore, the first and second positioning right-angle blocks are provided with through holes corresponding to the positioning points, and small magnets are also embedded in the corresponding positions on the lower plate surfaces of the two right-angle blocks.
[0014] Furthermore, both the first and second positioning right-angle blocks have pressure strips on their upper surfaces, and the pressure strips have a T-shaped cross-section.
[0015] Furthermore, the flipping mechanism includes a first bushing fixed on the upper surface of the fixture substrate, a second bushing fixed on the lower surface of the positioning right-angle block, and a rotating shaft connected in the shaft holes of the first bushing and the second bushing.
[0016] Compared with the prior art, this invention provides a stacking fixture, including a fixture base plate, a first positioning right-angle block, and a second positioning right-angle block. A flipping mechanism is provided between the first and second positioning right-angle blocks and the fixture base plate. The first and second positioning right-angle blocks are pivotally connected to opposite sides of the fixture base plate via the flipping mechanism, and are staggered along the length of the fixture base plate. A right-angle positioning reference composed of at least three positioning posts is provided on the upper surface of the fixture base plate. The following advantages are achieved: 1. By staggering the two positioning right-angle blocks along the length of the fixture base plate, interference during the pressing of different material layers is avoided, and a horizontal placement reference is established for different material layers. 2. By designing a right-angle positioning reference composed of at least three positioning posts, a positioning constraint is formed for the initial horizontal placement of the material layers. 3. This stacking fixture can be applied to positioning materials of different sizes stacked together, reducing material waste. 4. The positioning holes of the material are located at the four corners. The outer film material can completely cover the inner resin material, preventing the resin from overflowing from the positioning holes onto the mold. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a stacking fixture, including a fixture base plate 1, a first positioning right-angle block 2, and a second positioning right-angle block 3. A flipping mechanism 4 is provided between the first positioning right-angle block 2 and the second positioning right-angle block 3 and the fixture base plate 1. The first positioning right-angle block 2 and the second positioning right-angle block 3 are pivotally connected to opposite sides of the fixture base plate 1 through the flipping mechanism 4, and the first positioning right-angle block 2 and the second positioning right-angle block 3 are staggered in the length direction of the fixture base plate 1. A right-angle positioning reference composed of at least three positioning posts 5 is provided on the upper surface of the fixture base plate 1. By staggering the two positioning right-angle blocks in the length direction of the fixture base plate 1, interference of the right-angle block movement is avoided when pressing different material layers, and a horizontal placement reference is formed for different material layers. In addition, by designing a right-angle positioning reference composed of at least three positioning posts 5, a positioning constraint is formed for the initial horizontal placement of the material layers.
[0024] Please see Figure 3 The upper edge of the fixture base plate 1 is provided with a mounting groove 6 for the flipping mechanism 4 to be installed therein. By designing the mounting groove 6, the flipping mechanism 4 can be easily embedded therein, effectively reducing the area occupied by the flipping mechanism 4 in the entire stacking fixture. While ensuring the structural strength of the fixture base plate 1, the thickness of the fixture base plate 1 can be appropriately reduced, and the interference area of the flipping mechanism 4 on the operation area can be reduced. The fixture base plate 1 is made of graphite material.
[0025] Please see Figure 3 The upper edge of the fixture base plate 1 is provided with positioning points 7 for positioning during the pressing operation of the right-angle blocks. The first positioning right-angle block 2 and the second positioning right-angle block 3 are provided with through holes corresponding to the positioning points 7. When the positioning right-angle blocks are pressed together, the positioning points 7 and the through holes form a fast and stable limiting structure, preventing the positioning right-angle blocks from shifting and causing reference errors, and making it convenient for operators to judge whether the right-angle blocks are in place.
[0026] Please see Figure 3 The upper edge of the fixture substrate 1 is provided with small magnets 8 for magnetic attraction during the pressing operation of the right-angle blocks, and small magnets 8 are also provided at corresponding positions on the lower surfaces of the two right-angle blocks. By designing small magnets 8 on the fixture substrate 1 and the right-angle blocks respectively, magnetic attraction and pressing are formed, which further strengthens the horizontal and tight pressing between the right-angle blocks and the fixture substrate 1, providing a better scenario for the subsequent placement of thin film material layers.
[0027] Please see Figures 1-2 The upper surfaces of the first positioning right-angle block 2 and the second positioning right-angle block 3 are both provided with pressure strips 9, and the cross-section of the pressure strips 9 is T-shaped. By designing the pressure strips 9, a concentrated downward pressure force can be applied to the pressure strips 9, so that the right-angle blocks are horizontally pressed into the fixture base plate 1. Furthermore, the right-angle blocks can be quickly flipped and lifted by gripping the pressure strips 9, and the pressure strips 9 provide horizontal support for the outwardly unfolding right-angle blocks.
[0028] Please see Figure 4 The flipping mechanism 4 includes a first bushing 41 fixed to the upper surface of the fixture base plate 1 by screws 44, a second bushing 42 fixed to the lower surface of the positioning right-angle block by screws 44, and a rotating shaft 43 connected in the shaft holes of the first bushing 41 and the second bushing 42. The flipping mechanism 4 is designed to enable the right-angle block to quickly switch between a pressed state and an unfolded state.
[0029] Working principle: The release film is placed horizontally on the right-angle positioning reference on the fixture substrate 1. It should be noted that the four corners of the release film are processed to form right-angle cuts (notches). The release film is positioned by aligning three right-angle cuts with the positioning post 5. Then, the first positioning right-angle block 2 is flipped and pressed onto the release film. Next, multiple PP films are taken and placed horizontally on the upper surface of the release film with the first positioning right-angle block 2 as the reference. Then, the second positioning right-angle block 3 is flipped and pressed onto the PP film. Then, leather material is taken and placed horizontally on the upper surface of the release film with the second positioning right-angle block 3 as the reference. Using the right-angled positioning block 3 as a reference, place it horizontally on the upper surface of the PP film. Use an ultrasonic spot welding gun to fix the leather material onto the PP film. Then, flip the first right-angled positioning block 2 and the second right-angled positioning block 3 outwards and open them. Next, take a TPU film and place it on the upper surface of the leather material. Then, take a release film and cover it with the bottom release film. The placement of the upper release film is also done by aligning the three right-angled cuts with the positioning post 5 to form the release film positioning. Then, use an ultrasonic spot welding gun to fix the above materials together, thus completing the multi-layer film material stacking and packaging.
