A fixing carrier for terminal dispensing

Abstract

A fixing carrier for terminal dispensing, belonging to the field of FPC terminal fixing technology, includes several barbed metal strips and parallel FPC film lines that cooperate with the metal strips. Each parallel FPC film line contains several flat copper wires. Each flat copper wire at the end of the parallel FPC film line is pierced and securely fastened to each metal strip. The parallel FPC film lines are fixed to a base, which has a perforated window. The perforated window contains all the ends and metal strips. A fixing mechanism is provided within the perforated window to secure the ends and metal strips together. Considering the need to adjust the flatness of FPCA (Flexible Printed Circuit), this fixing carrier provides a method where, after positioning the irregularly shaped terminal, a reverse force is applied to the pierced and crimped position. This reduces the warping deformation of the pierced area due to the force exerted by the irregularly shaped terminal, allowing for uniform application of adhesive to the surface of the pierced and crimped area.

Description

Technical Field

[0001] This application belongs to the field of terminal fixing technology of FPC, and specifically relates to a fixing carrier for terminal dispensing. Background Technology

[0002] In direct welding projects involving piercing and crimping, after the terminal pierces the metal part of the FPC and is fixed in place, the front and back sides of the FPC and the terminal body in the pierced area need protection. Generally, this is done by covering with adhesive, which then cures to form a strong protective layer. However, in the published document CN110224242A, which describes a method for connecting piercing terminals, a stamping strip, and the stamping strip to parallel lines on the FPC film, electrical connection is achieved between two piercing terminals and the two flat copper wires at the ends of the parallel lines on the FPC film. This effectively ensures the reliability of the electrical connection between the piercing terminals and the two flat copper wires at the ends of the parallel lines on the FPC film.

[0003] However, the adhesive used to cover the puncture crimping area is a UV adhesive. The inherent characteristics of UV adhesive and the required adhesive coverage size, coupled with insufficient positioning accuracy, can easily lead to adhesive being sprayed onto the carrier or FPC, and uneven coating height on the terminal surface. The problem stems from the fact that the puncture area of ​​the terminal requires adhesive to cover the metal. Because the FPC warps after the crimping, this warping cannot be eliminated after being placed on the original adhesive carrier. Even after uniform adhesive application, the warped deformation of the FPC prevents complete coverage of the metal in the puncture area. The applicant's actual solution was to use a steel sheet to cover the deformed area and use the magnetic attraction of the carrier to flatten the warped area. However, since the warped area is the puncture crimping area, the steel sheet cannot effectively apply adhesive, making implementation extremely difficult. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a fixing carrier for terminal dispensing, which, after positioning the irregularly shaped terminal, applies reverse force to the piercing and crimping position, thereby reducing the warping and deformation of the pierced area due to the force exerted by the irregularly shaped terminal position, and allowing the surface of the pierced and crimping area to be evenly coated with adhesive.

[0005] To achieve the above technical objectives, the following technical solution is provided: a fixing carrier for terminal dispensing, comprising a plurality of barbed metal strips and FPC film parallel lines that cooperate with the metal strips. The FPC film parallel lines have a plurality of flat copper wires. Each flat copper wire at the tail end of the FPC film parallel line is pierced and fastened to each metal strip. The FPC film parallel lines are fixed on a base, and a hollow window is provided on the base. The hollow window contains all the tail ends and metal strips. A fixing mechanism is provided in the hollow window to fasten the tail ends and metal strips together.

[0006] In one feasible embodiment, the fixing mechanism includes a first fixing band, the two ends of which are fixed to the lower base of the base, and the middle part extends through the entire openwork window in the length direction.

[0007] The second fixing strap has its two ends fixed to the upper base of the base, and its middle part runs through the entire hollow window in the length direction;

[0008] After the first and second fixing straps are aligned with the lower and upper bases, they clamp the tail end and the metal strip.

[0009] In one feasible embodiment, there are fasteners between the two ends of the first fixing strap and the lower base of the base. The fasteners include slots that mate with the ends of the first fixing strap. A tensioning groove is provided on the side of the slot, and a tensioning block is embedded in the tensioning groove. The ends of the first fixing strap are engaged in the slot by the tensioning block being embedded in the tensioning groove.

[0010] In an implementable manner, an alignment assembly is provided between the lower base and the upper base. The alignment assembly includes a plurality of lower through holes formed on the lower base and a plurality of upper through holes formed on the upper base. The lower through holes and the upper through holes are aligned one by one and coaxially arranged.

[0011] It also includes alignment pins installed in the lower through hole, which extend into the upper through hole to achieve alignment between the lower base and the upper base.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The carrier of the above technical solution can avoid metal exposure in the puncture area, reducing the appearance defects of adhesive application by more than 5%; it also achieves precise positioning of terminals, improves the pass rate of AVI inspection equipment, avoids secondary inspection, and improves production efficiency by more than 10%.

[0019] like Figure 1 , Figure 2 and Figure 3 The illustrated embodiment provides a fixing carrier for terminal dispensing, comprising a plurality of barbed metal strips 1 and FPC film parallel lines 2 that cooperate with the metal strips 1. Each FPC film parallel line 2 contains a plurality of flat copper wires 3. Each flat copper wire 3 at the tail end of the FPC film parallel line 2 is punctured and securely fastened to each metal strip 1. The FPC film parallel lines 2 are fixed to a base 4, which has a perforated window 5. The perforated window 5 contains all the tail ends and metal strips 1. A fixing mechanism 6 is provided within the perforated window 5 to secure the tail ends and metal strips 1 together. Adhesive can be applied to the punctured and crimped areas within the perforated window 5.

[0020] In this embodiment, the fixing mechanism 6 includes a first fixing band 61. The two ends of the first fixing band 61 are fixed to the lower base of the base 4, and the middle part extends through the entire hollow window 5 in the length direction. The first fixing band 61 is a steel sheet, and the terminal is pressed with the steel sheet after the FPC is set.

[0021] The second fixing band 62 is fixed at both ends to the upper base of the base 4, and the middle part runs through the entire hollow window 5 in the length direction; the second fixing band 62 is fixed at the terminal step, 1mm away from the edge of the FPC, so as to avoid glue overflow.

[0022] After the first fixing band 61 and the second fixing band 62 are aligned and fitted together with the lower base and the upper base, they clamp the tail end and the metal band 1. After the terminal is fixed, glue is applied evenly, ensuring that the internal flat copper wire 3 and the burrs of the metal band 1 are not exposed. By reversing the terminal to position the FPC, the first fixing band 61 and the second fixing band 62 are used to fix the terminal upright and make it horizontal. The punctured area is affected by the reverse force of the terminal, and the surface of the warped area is flat after being stressed.
