Description

Technical Field

[0001] This utility model relates to the field of circuit board tray technology, and in particular to turnover trays for flexible circuit board production. Background Technology

[0002] During the production and turnover process, flexible circuit boards need to be carried and transported using turnover pallets, especially for large flexible circuit boards, which require high protection performance from the pallets.

[0003] Existing turnover pallets are mostly made of a single material, which is not enough to prevent static electricity. Large flexible circuit boards are more prone to static electricity accumulation on their surface due to their large size. This may not only damage the delicate circuits inside the circuit board, but also attract dust from the environment, thus affecting product quality.

[0004] To address the aforementioned issues, this utility model document proposes a turnover tray for flexible circuit board production. Utility Model Content

[0005] This utility model provides a turnover tray for flexible circuit board production, which solves the shortcomings of the prior art, where turnover trays are mostly made of a single material, have insufficient anti-static ability, and large flexible circuit boards are more prone to static electricity accumulation on the surface.

[0006] This utility model provides the following technical solution:

[0007] Turnover pallets for flexible circuit board manufacturing include:

[0008] A rectangular plate has a rectangular groove at the center of its top, into which a large flexible circuit board body is embedded. A rectangular hole is provided at the bottom of the inner wall of the rectangular groove, and a pad for guiding flow is provided in the rectangular hole.

[0009] In one possible design, positioning posts are fixedly provided at the four corners of the bottom of the inner wall of the rectangular groove, and positioning through holes for the top of the corresponding positioning posts are provided at the four corners of the flexible circuit board body.

[0010] In one possible design, the pad has a rectangular array of multiple pre-drilled holes, and a corresponding conductive fiber post is fixed through each pre-drilled hole.

[0011] In one possible design, the bottom of the pad extends through the rectangular hole and is fixedly fitted with a guide plate.

[0012] In one possible design, both sides of the rectangular plate are provided with U-shaped notches to facilitate the removal of the flexible circuit board body, and the guide plate has the same size as the rectangular plate.

[0013] In one possible design, the four corners of the bottom of the deflector are provided with docking slots for inserting another tray.

[0014] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0015] The working principle and usage process of this technical solution are as follows:

[0016] When using, ensure that the turnover pallet is placed on a horizontal working surface, such as a production line operating table, with the bottom of the guide plate in contact with the table surface, keeping the pallet stable. The top of the conductive fiber pillars on the pad slightly protrudes from the pad surface, forming a complete electrostatic conduction carrier. The operator aligns the large flexible circuit board body with the rectangular slot on the top of the rectangular plate, so that the positioning through holes at the four corners of the FPC are accurately fitted into the positioning pillars at the bottom of the rectangular slot. Gently lower the FPC until its bottom is in contact with the pad surface, and the top of the positioning pillar penetrates through the positioning through hole, achieving precise positioning of the FPC in the slot. At this time, the bottom of the FPC and the conductive fiber pillars on the pad form multi-point contact. The static electricity generated during the production or turnover of the FPC is quickly conducted to the pad through the multi-point contact between its bottom and the conductive fiber pillars, and then conducted to the guide plate through the pad. Finally, it is discharged through the guide plate and the external contact surface or indirect grounding structure to avoid static electricity accumulation.

[0017] When stacking multiple layers, the mating groove at the bottom of the guide plate of the upper tray precisely fits into the top of the positioning post of the lower tray, realizing the positioning and stacking between the trays. This avoids squeezing the FPC in the lower tray during stacking, preventing FPC deformation or pin damage. When removing the FPC, the operator can insert their fingers or use tools to lift the edge of the FPC through the U-shaped notches on both sides of the rectangular plate and pull it upward to remove the FPC, avoiding scratching the edge or pin of the FPC during handling.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, the conductive fiber pillars arranged in a rectangular array on the pad form a multi-point contact with the bottom of the FPC, resulting in a shorter and more uniform electrostatic conduction path. This allows for the rapid discharge of static electricity accumulated on the surface of the FPC, preventing electrostatic discharge from damaging the internal precision circuits or attracting dust. Furthermore, the conductive fiber pillars are embedded and fixed, making them less prone to wear and tear compared to surface-coated antistatic layers, thus ensuring stable antistatic performance during long-term use.

[0020] In this invention, the positioning posts precisely match the positioning through holes at the four corners of the FPC, enabling the FPC to be positioned without displacement within the tray. The rectangular slots are specifically designed for large FPCs, and together with the limiting effect of the positioning posts, they can be adapted to large-size flexible circuit boards, reducing the risk of FPC bending and deformation.

[0021] In this invention, the mating groove and positioning post structure ensure accurate positioning and structural stability when the pallet is stacked in multiple layers, avoiding damage to the FPC caused by stacking and squeezing; the U-shaped notch provides convenient space for picking and placing.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] In one embodiment:

[0031] Please refer to Figure 1-4 Turnover pallets, including:

[0032] A rectangular plate 1 is a horizontally placed plate-like structure with a rectangular groove 3 recessed downwards at the top center. The outline of the rectangular groove 3 is adapted to the shape of the flexible circuit board body 2, and can completely accommodate the flexible circuit board body 2. The four corners of the bottom of the inner wall of the rectangular groove 3 are fixedly connected to stainless steel positioning posts 4. The positioning posts 4 extend vertically, and positioning through holes 5 are opened at the corresponding positions of the four corners of the flexible circuit board body 2. The diameter of the positioning through holes 5 matches the outer diameter of the positioning posts 4, ensuring that the positioning posts 4 can smoothly pass through the positioning through holes 5.

[0033] A rectangular hole 6 is opened at the bottom of the inner wall of the rectangular groove 3. The size of the rectangular hole 6 is smaller than the size of the rectangular groove 3. The pad 7 is embedded in the rectangular hole 6 and fits tightly against the inner wall of the rectangular hole 6. The pad 7 is made of conductive silicone material, and its surface has multiple reserved holes distributed in a rectangular array. A conductive fiber post 8 is fixed in each reserved hole. The conductive fiber post 8 and the pad 7 are fixed by a hot pressing process. The conductive fiber post 8 is made of metallized fiber material with a surface coating to improve conductivity, while maintaining the flexibility of the fiber. The top of the conductive fiber post 8 protrudes slightly from the upper surface of the pad 7. The height of the part protruding from the pad 7 is controlled within the range that does not affect the stable placement of the flexible circuit board body 2.

[0034] The bottom of the pad 7 extends to the outside of the rectangular hole 6. The guide plate 10 is fixedly connected to the bottom of the pad 7. The guide plate 10 is a conductive metal plate made of nickel-plated aluminum alloy, which not only has excellent conductivity but also strong corrosion resistance. Its external dimensions are consistent with those of the rectangular plate 1, making the overall structure of the tray regular. U-shaped notches 9 are opened on both sides of the rectangular plate 1. The openings of the U-shaped notches 9 face the rectangular groove 3. The notches make it convenient for operators to insert their fingers or tools without compromising the overall structural strength of the rectangular plate 1.

[0035] During use, the flexible circuit board body 2 is placed in the rectangular groove 3 through the positioning through hole 5 and the positioning post 4. Its bottom forms multi-point contact with the conductive fiber post 8 on the pad 7. The static electricity generated during turnover or production is conducted to the pad 7 through the conductive fiber post 8, and then transferred to the guide plate 10 through the pad 7. Finally, it is discharged through the contact between the guide plate 10 and the placement surface. When picking up and placing the flexible circuit board body 2, the operator can lift its edge through the U-shaped notch 9 to complete the lifting action. The whole operation process is stable and will not cause damage to the flexible circuit board body 2.

[0036] This application can be used for flexible circuit board trays, or in other fields applicable to this application.

[0037] In another embodiment:

[0038] Turnover pallets for flexible circuit board production, used in the field of circuit board pallets;

[0039] Please refer to Figure 2 The bottom of the guide plate 10 is provided with a docking groove 11 corresponding to the position of the positioning post 4. The inner diameter of the docking groove 11 is adapted to the outer diameter of the top of the positioning post 4. When multiple pallets are stacked, the docking groove 11 of the upper pallet can be precisely fitted into the top of the positioning post 4 of the lower pallet to realize the positioning limit between the pallets and prevent the pallets from shifting or squeezing the flexible circuit board body 2 below.
