Description

Technical Field

[0001] This utility model belongs to the field of FPC processing technology, specifically relating to a positioning device and an FPC processing apparatus. Background Technology

[0002] FPC, or Flexible Printed Circuit Board, is a type of bendable printed circuit board made with polyimide or polyester film as the substrate. Its core feature lies in the use of a flexible insulating substrate (such as polyimide or polyester film), into which conductive lines are embedded using precision processes, allowing for free bending, folding, or rolling in three-dimensional space. FPCs are characterized by high reliability, thinness, and flexibility, and are widely used in consumer electronics, the automotive industry, and aerospace.

[0003] Before mounting electronic components onto an FPC board, the FPC board typically needs to be fixed to a positioning carrier. Positioning pins on the carrier engage with holes on the FPC board for positioning and limiting. For example, Chinese Patent Publication No. CN218217839U discloses an FPC board positioning and fixing device. This device fixes the FPC carrier to a base plate using carrier positioning pins and FPC positioning pins, and then secures the FPC board using the FPC positioning pins. By providing component clearance holes in the receiving grooves corresponding to the shapes of the FPC components, damage to the FPC components and deformation of the FPC board can be prevented. By designing FPC carriers with different receiving grooves and replacing them, it can be adapted to different FPC boards, thus meeting certain usage requirements. However, the FPC positioning pins are fixed to the base plate and cannot be flexibly adjusted, meaning the carrier is only suitable for a single type of FPC board. This limits the carrier's applicability and prevents it from meeting the positioning and fixing needs of various FPC boards.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a positioning device and an FPC processing apparatus.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0028] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0029] like Figures 1 to 6 As shown, a positioning device according to one embodiment of the present invention includes a carrier 1, at least two positioning pins 2, and at least two pressure plates 3. The carrier 1 has a plurality of evenly distributed insertion holes 101. Each positioning pin 2 includes a pin 201 and a telescopic component. The telescopic component is connected to the lower side of the pin 201, allowing the pin 201 to pass through any one of the insertion holes 101 from the lower side of the carrier 1. The telescopic component is used to adjust the length of the positioning pin 2 extending out of the insertion hole 101. An insertion rod 301 is fixedly connected to the pressure plate 3. The insertion rod 301 can pass through any one of the insertion holes 101 from the upper side of the carrier 1 and is used to fix the FPC board through the cooperation of the positioning pins 2 and the pressure plate 3.

[0030] Place the FPC board on carrier 1 and determine the corresponding positions of the positioning holes and insertion holes 101 on the FPC board. Remove the FPC board, then flip carrier 1 and insert multiple pins 201 into the insertion holes 101 at the determined positions. Flip carrier 1 again; at this time, one end of the pin 201 can protrude from the insertion hole 101, and the length of the positioning pin 2 extending out of the insertion hole 101 can be adjusted by the telescopic component. Then, place the FPC board back on carrier 1 so that the pins 201 can pass through the positioning holes on the FPC board, achieving initial fixation of the FPC board. Finally, insert multiple insertion rods 301 into multiple insertion holes 101 so that the pressure plate 3 can press down on the side of the FPC board, such as... Figure 1 As shown, this allows for the positioning and fixing of the FPC board.

[0031] This application allows for the determination of the insertion hole 101 based on the positioning holes on the FPC board. Then, the pin 201 is inserted accordingly, and the pressure plate 3 presses down on the side of the FPC board to achieve positioning and fixation. This not only facilitates operation but also allows the carrier 1 to be used for positioning and fixing various types of FPC boards, thereby expanding the applicability of the carrier 1 and meeting user needs.

[0032] like Figure 1 As shown, the carrier 1 includes a carrier part 01 and a pair of support parts 02. The pair of support parts 02 are symmetrically connected to both sides of the carrier part 01. The carrier part 01 and the support parts 02 form a convex structure, and the insertion hole 101 passes through the carrier part 01. The convex structure facilitates the adjustment of the telescopic component to adjust the length of the pin 201 protruding from the insertion hole 101.

[0033] like Figures 1 to 6 As shown, the telescopic assembly includes a fixed end 202, a sliding end 203, and a fastening screw 204. The fixed end 202 is fixedly connected to the bottom of the pin 201. One end of the sliding end 203 is slidably disposed inside the fixed end 202. The sliding end 203 is threadedly connected to the side wall of the fixed end 202 and corresponds to the sliding end 203. Loosening the fastening screw 204 allows the sliding end 203 to move relative to the fixed end 202, thereby adjusting the overall length of the telescopic assembly. This facilitates adjusting the length of the pin 201 protruding into the insertion hole 101 according to different FPC boards, meeting the positioning and fixing requirements of the FPC board.

[0034] Preferably, the lower end face of the sliding end 203 is flush with the lower bottom face of the support part 02 so that the pin 201 can be inserted into the positioning hole on the FPC board for positioning and fixing the FPC board.

[0035] In this embodiment, the distance between the sliding end 203 and the pin 201 is greater than the height of the support part 02, so that the pin 201 is not in a suspended state, thereby ensuring the protruding length of the pin 201 so that it can be inserted into the positioning hole on the FPC board.

[0036] like Figures 1 to 6 As shown, the diameter of the insertion rods 301 is smaller than the diameter of the insertion holes 101, and the insertion rods 301 are made of metal. When the insertion rods 301 are inserted into the insertion holes 101, the pressure plate 3 can press down on the edge of the FPC board under the action of the counterweight of the insertion rods 301, so as to further fix the FPC board.

[0037] like Figures 1 to 6 As shown, an expansion ring 205 is sleeved on the side wall of the pin 201. The expansion ring 205 is located on the upper side of the carrier 1. The diameter of the expansion ring 205 is larger than the diameter of the insertion hole 101, which can realize the diameter change effect of the pin 201 to adapt to different diameters of the positioning holes on the FPC board and ensure the positioning and fixing effect of the FPC board.

[0038] The expandability of the expansion ring 205 also prevents damage to the positioning holes of the FPC board.

[0039] The pin 201 is threaded to a screw 206. A piston 207 is rotatably connected to one end of the screw 206 within the pin 201. A cavity 208, matching the piston 207, is provided within the pin 201. The piston 207 slides within the cavity 208, and its diameter is the same as the cavity 208's diameter. When the screw 206 rotates, the piston 207 can move within the cavity 208. If the screw 206 is screwed in, the piston 207 compresses the space within the cavity 208, increasing the pressure inside. If the screw 206 is screwed out, it does not compress the gas in the cavity 208, thus reducing the pressure inside.

[0040] Additionally, a connecting pipe 209 connects the cavity 208 and the expansion ring 205. When the screw 206 is screwed in, the piston 207 compresses the space in the cavity 208 and increases the pressure inside the cavity 208. At this time, some of the gas inside the cavity 208 enters the expansion ring 205 through the connecting pipe 209, causing the expansion ring 205 to expand and increase the diameter of the pin 201. When the screw 206 is screwed out, the piston 207 does not compress the space in the cavity 208 and reduces the pressure inside the cavity 208. At this time, some of the gas inside the expansion ring 205 enters the cavity 208 through the connecting pipe 209, causing the expansion ring 205 to contract and decrease the diameter of the pin 201. By expanding and contracting the expansion ring 205, the diameter of the pin 201 is changed to accommodate different positioning hole diameters on FPC boards, thus expanding the overall applicability range.

[0041] An FPC processing apparatus includes the aforementioned positioning device.

[0042] In summary, this application, by allowing the pin 201 and insertion rod 301 to be inserted into any one of the insertion holes 101, can position and fix different FPC boards. This not only facilitates operation but also expands the applicability of the carrier 1, meeting user needs. Furthermore, the variable diameter of the pin 201, accommodating different diameters of the positioning holes on various FPC boards, further expands the overall applicability.

[0043] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
