Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED bracket manufacturing, and more particularly to an LED electrode sheet strip and an LED bracket. Background Technology
[0002] Figure 1 The existing material strip is shown. Figure 3 This illustrates the molding of an LED bracket on a strip, where the LED bracket is injection molded. Figure 14 This is a 3D view of an existing LED bracket.
[0003] from Figure 2 It can be seen that the strip has multiple hollow holes, and during injection molding, the mold core M passes directly through these holes.
[0004] In actual production, due to the small gap between the mold core M and the inner wall of the hole, it is difficult to prevent the side wall of the mold core M from contacting the strip. This contact will cause wear on the mold core M, and damage to the mold core M will result in burrs on the side of the product. Replacing the mold core M will further increase production costs. Figure 4 The dashed area in the diagram represents the location where the mold core M contacts the product.
[0005] Currently, burrs are allowed in area a of the LED bracket, while area b has strict requirements and burrs are not allowed. Therefore, the main problem at present is how to solve the problem of increased costs caused by replacing the mold core M. Utility Model Content
[0006] To address the aforementioned issues, this invention provides an LED electrode sheet strip, an LED bracket, and a method for preparing the LED bracket, which aims to solve the problem of increased costs caused by replacing the mold core.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is: an LED electrode strip, comprising a strip body, the strip body having a graphic area for injection molding, characterized in that the graphic area includes a first hollow portion and a second hollow portion that are interconnected, the second hollow portion being used for fluid in the molding injection process, the first hollow portion being penetrated by a mold core, and the mold core and the second hollow portion forming a mold cavity.
[0008] Furthermore, the second hollow portion includes a set of symmetrical, L-shaped second hollow sections, wherein the second hollow section includes a first extended area.
[0009] Furthermore, the second hollow portion includes a first hollow portion located between the two second hollow portions, wherein the first hollow portion is linear in shape and a second extended area is provided on the edge area of the first hollow portion.
[0010] Furthermore, the graphic area has multiple sections, and there are also folded-leg areas between adjacent graphic areas for connection with the LED bracket.
[0011] An LED bracket includes a body and LED electrode sheets disposed on the body. The bracket is characterized in that a protrusion is provided on the body, which is disposed on the outer side of the body and located between the upper and lower mold cores, for embedding into a second hollow portion in the strip body.
[0012] Furthermore, the outer side of the body includes sloping walls, with protruding parts located at the corners of the body or on the sloping walls.
[0013] Furthermore, the outer side of the body includes sloping walls, with protruding parts distributed at the corners of the body and on the sloping walls.
[0014] Furthermore, the protrusion includes a first molding component and a second molding component, which respectively cooperate with the first extended area and the second extended area in the second hollowed-out portion.
[0015] A method for manufacturing an LED bracket:
[0016] S1, pre-stamping is performed on the strip body to form multiple graphic areas on the strip body;
[0017] S2, electroplating on the strip body;
[0018] S3, the strip body is placed into the mold. After the mold is closed, the first forming part of the upper mold core passes through the first hollow part, the second forming part is located above the second hollow part and the first hollow part, and the third forming part is located below the strip body. After the plastic fluid is injected, the plastic fluid forms the corresponding shape along the first forming part and the third forming part. At the same time, the plastic fluid also flows from the first hollow part to the second hollow part and the first hollow part.
[0019] S4, after demolding, an LED bracket is formed. The folding foot area is cut to form a bendable connecting piece on the strip.
[0020] S5, by bending the connecting piece, the connecting piece is made to fit tightly against the side of the LED bracket body.
[0021] This invention improves the structure of the strip, thereby changing the use of the mold core on the strip. The strip has two hollowed-out sections. The first hollowed-out section is for the mold core to pass through, while the second hollowed-out section is for shaping the fluid. In other words, the use of the second hollowed-out section is set to allow the injection fluid to pass through only, without the mold core needing to pass through the second hollowed-out section. This avoids contact between the mold core and the second hollowed-out section, thus solving the problem of high costs caused by replacing the mold core. Attached Figure Description

[0040] Figure 19 The image shows one of the electroplating areas F on the strip body. Detailed Implementation
[0041] The LED electrode strip includes a strip body 1, which has a graphic area for injection molding. The graphic area includes a first hollow portion 1a and a second hollow portion 1b that are interconnected. The second hollow portion 1b is used for fluid in the molding injection process. The first hollow portion 1a is passed through by a mold core 2, and the mold core 2 and the second hollow portion 1b form a mold cavity.
[0042] This invention improves the structure of the strip, thereby changing the use of the mold core on the strip. The strip body 1 has two hollowed-out parts. The first hollowed-out part 1a is used for the mold core 2 to pass through, while the second hollowed-out part 1b is used to shape the fluid. In other words, the use of the second hollowed-out part 1b is set to allow the injection fluid to pass through only, without the mold core 2 needing to pass through the second hollowed-out part 1b. This avoids contact between the mold core 2 and the second hollowed-out part 1b, thus solving the problem of high cost caused by replacing the mold core 2.
[0043] Furthermore, the second hollow portion 1b includes a set of L-shaped second hollow portions 100 that are symmetrical to each other. The second hollow portion 100 includes a first extended region 1b-1, which is for forming a first molded part 3a located outside the body of the LED bracket 3 on the side of the LED bracket 3.
[0044] Furthermore, the second hollow portion includes a first hollow portion 101 located between the two second hollow portions 100, wherein the first hollow portion 101 is linear in shape, and a second extended region 1b-2 is provided on the edge region of the first hollow portion 101. The second extended region 1b-2 is for shaping the injection fluid, so that a second molded part 3b located outside the body of the LED bracket 3 is formed on the side of the LED bracket 3.
[0045] Furthermore, there are multiple graphic regions, and adjacent graphic regions are also connected by a folded area 4 (such as...). Figure 11 The portion highlighted in the middle is used for connection with LED bracket 3.
[0046] An LED bracket 3 includes a body and an LED electrode sheet disposed on the body. The body also has a protrusion that protrudes from the outside of the body and is located between the upper mold core 21 and the lower mold core 22 for embedding into the second hollow portion of the strip body 1. The LED electrode sheet is a connecting piece 11.
[0047] Furthermore, the outer side of the body includes an inclined wall 31, with protruding portions distributed at the corners 32 of the body or on the inclined wall 31.
[0048] Furthermore, the outer side of the body includes an inclined wall 31, with protruding portions distributed at the corners 32 of the body and on the inclined wall 31.
[0049] Furthermore, the protrusion includes a first molding part 3a and a second molding part 3b, which respectively cooperate with the first extended region 1b-1 and the second extended region 1b-2 in the second hollowed-out portion.
[0050] The traditional LED bracket 3 design limits the design and function of the cutout portion of the material strip. The new LED bracket 3, through its improved structure and the redesign of the first molding part 3a and the second molding part 3b, eliminates the step of the mold core 2 entering the second cutout portion (area b referred to in the background art) in the entire production process. As a result, this new design of the LED bracket 3 saves a lot of production costs, reduces the number of mold cores 2 used, and further reduces the requirements for the mold core 2.
[0051] The manufacturing process of LED bracket 3 is as follows:
[0052] S1, stamping is performed on the strip body 1 in advance, and multiple graphic areas are formed on the strip body 1 by stamping;
[0053] S2, Electroplating is performed on the strip body 1, and the electroplating area is... Figure 19 The F area is selected in the middle box.
[0054] S3 (e.g.) Figure 15-16 As shown), the strip body 1 is placed into the mold. After the mold is closed, the first forming part 21a of the upper mold core 21 passes through the first hollow part 1a, the second forming part 21b is located above the second hollow part 100 and the first hollow part 101, and the third forming part 22a is located below the strip body 1. After the plastic fluid is injected, the plastic fluid forms the corresponding shape along the first forming part 21a and the third forming part 22a. At the same time, the plastic fluid also flows from the first hollow part 1a to the second hollow part 100 and the first hollow part 101.
[0055] S4, after demolding, the folded leg area 4 is cut to form a bendable connecting piece 11 on the strip (e.g., Figure 12 (as shown)
[0056] S5, by bending the connecting piece 11, the connecting piece 11 is connected to the LED bracket 3 (e.g., Figure 13 (As shown).
[0057] It should be noted that this preparation method can also optimize the electroplating process, such as... Figure 13 The contact surface 200 shown does not require electroplating, while in the prior art, the contact surface 200 has nickel and silver layers. Therefore, this invention also optimizes the electroplating process and reduces the loss of nickel and silver.
[0058] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
