Abstract
Description
Technical Field
[0001] This application belongs to the technical field of dispensing carriers for flexible printed circuit boards, and specifically relates to a general carrier for dispensing adhesive. Background Technology
[0002] After FPCs are assembled using SMT processes, they form FPCA assemblies. Connectors, NTCs, and other functional components require adhesive sealing. Due to the varying shapes of FPCs, the original dispensing carriers were positioned in grooves according to the product's shape, requiring a separate carrier development for each product. Existing dispensing carriers need to be positioned in grooves according to the product's shape to achieve dispensing component positioning, flux residue avoidance, and 2D front / back recognition.
[0003] The CN217491524U publication discloses a dispensing carrier with a positioning function for flexible printed circuit board production, which provides a dispensing carrier with a dedicated carrier head. The CN218167627U publication discloses an adjusting bracket for a dispensing carrier, which provides a main chamber for dispensing FPCA. It can be seen that the dispensing in the prior art is set up separately for each part. This not only increases the number of operating procedures but also the number of related carriers. For example, a current production line must produce at least one model and four products. Each product requires 60 dispensing carriers, so each line needs to be equipped with 60 * 40 = 240 dispensing carriers. The carrier investment cost is too high, significantly increasing the company's production costs. Utility Model Content
[0004] The purpose of this invention is to address the problem of the wide variety of carriers currently available. It provides a universal carrier by dividing functional areas according to the shape of the FPC, allowing products with different shapes to share a single carrier body. It also enables 2D scanning, secondary heating and evaporation of flux without residue, and reduces the number of carriers that need to be developed.
[0005] To achieve the above technical objectives, the following technical solution is provided: a universal carrier for dispensing adhesive, having a base, the base being a long rectangular strip, with precision positioning square grooves parallel to the width side provided at both ends of the base, wherein several parallel channels are formed between the precision positioning square grooves, each channel being parallel to the length side of the base; and the depth of the precision positioning square groove is greater than the depth of the channel.
[0006] In one feasible approach, the substrate has a region with several through slots located between precise positioning square slots and covered with several parallel channels.
[0007] In one feasible approach, at least one QR code recognition slot for storing a QR code is provided on the upper and lower surfaces of the area, respectively.
[0008] In an feasible embodiment, the through slots are arranged at an angle within the area, with a spacing of 30mm-40mm between them.
[0009] In an feasible implementation, the inclination angle between the through slot and the length or width side is 45°.
[0010] In feasible implementations, the channels are spaced 25mm-35mm apart; the channel width is between 8mm-10mm and the depth is between 0.2mm-1.0mm.
[0011] In one feasible approach, a dedicated carrier head is precisely positioned within the square groove.
[0012] In one feasible approach, a cover steel sheet is provided on the base to cover the base on which the FPCA and the special vehicle head are mounted.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] The universal carrier is compatible with different FPCA and dedicated carrier heads. Based on the number of carriers configured for the production line, the number of dispensing carriers required is reduced, resulting in a 75% reduction in carrier costs. Furthermore, in this technical solution, the through-holes are laid out in an inclined, elongated shape, reducing the unit weight of the carrier, minimizing equipment wear during transport, and extending equipment lifespan. Multiple QR code recognition slots enable product traceability and accurate input into the Internet of Things (IoT). Attached Figure Description

[0018] Figure 3 This is a schematic diagram of the structure covered with steel sheets; Detailed Implementation
[0019] like Figure 1 , Figure 2 and Figure 3 The illustrated embodiment provides a universal carrier for dispensing adhesive, comprising a base 1, which is a long rectangular strip. Precision positioning grooves 2, parallel to the width sides, are provided at both ends of the base 1. Several parallel channels 3 are formed between the precision positioning grooves 2, each channel 3 being parallel to the length side of the base 1. The depth of the precision positioning grooves 2 is greater than the depth of the channels 3. A dedicated carrier head is housed within each precision positioning groove 2, achieving precise positioning by using positioning inserts within the precision positioning grooves 2.
[0020] In this embodiment, the common body of the base 1 contains a general-purpose part, which is used to match the combination of dedicated positioning sub-blocks at both ends to complete the process positioning requirements of the product; the dedicated fixture part required to meet the production of each product is only the sub-block part; the overall cost is reduced.
[0021] In this embodiment, the channels 3 are spaced 25mm-35mm apart; the width of the channels 3 is between 8mm-10mm, and the depth is between 0.2mm-1.0mm. Preferably, the channels 3 are spaced 25mm apart; the width is 8mm, and the depth is 0.5mm. The channels 3 ensure that the overflow point of the FPC flux after secondary heating is above the settling tank, preventing the flux from directly contacting the carrier after overflow, thus improving evaporation efficiency.
[0022] In this embodiment, the base 1 has a region with a plurality of through slots 4, the region being located between the precision positioning square slots 2 and covered with a plurality of parallel channels 3.
[0023] Furthermore, at least one QR code recognition slot 6 for storing QR codes is provided on both the upper and lower surfaces of the area. Preferably, one QR code recognition slot 6 is provided on each of the upper and lower surfaces of the area.
[0024] In this embodiment, the through slots 4 are arranged at an angle within the region, with a spacing of 30mm-40mm between them. Preferably, the angle between the through slots 4 and the length or width side is 45°; and the spacing between them is 30mm. In this technical solution, the through slots 4 are used to set the fixture positioning PIN and QR code positioning, while enhancing the gas flow of the substrate 1 and improving the secondary evaporation efficiency of FLUX.
[0025] In this embodiment, the layout of the product can be adjusted in the area of the substrate 1, and the QR code recognition slot 6 allows for the display of the product QR code on both sides. FPCA is first placed on the substrate 1, ensuring the entire dispensing surface remains flat and avoiding flux overflow areas.
[0026] Then, based on the specific requirements of each product, special templates are configured at both ends, and special carrier heads are installed to contact the FPCA ends, thus achieving the purpose of addressing parts that cannot be used interchangeably.
[0027] Finally, a cover steel plate 5 is placed on top to cover the base 1 where the FPCA and special carrier head are installed, achieving the universality of the main body and reducing the total cost of the fixture investment.
