Description

Technical Field

[0001] This utility model relates to a tooling fixture for auxiliary production, belonging to the field of non-standard tooling fixture design. Specifically, it relates to a device for bending the pins of through-hole devices. Background Technology

[0002] Currently, due to the multi-variety, small-batch production model in avionics, through-hole devices require manual pre-forming before electrical assembly. Manually bending the leads of through-hole devices cannot guarantee consistency and efficiency. Inconsistent bending angles will significantly affect the product's contact signal and create difficulties in assembly. Different bending angles may also lead to localized wear or breakage, seriously affecting product quality, failing to meet factory pass rates, and increasing the number of rejected batches. Utility Model Content

[0003] Therefore, pin accuracy is crucial in the manufacturing process of through-hole devices. The design and implementation of auxiliary tooling and fixtures saves labor costs in the production process, improves production efficiency, and enhances process quality, yield, and production efficiency through precision control via fixtures. It also reduces rework and repairs.

[0004] Utility Model Purpose This utility model relates to the field of airborne electronic component processing technology, and specifically to a component lead bending and shaping fixture. This utility model uses a manually controlled miniature quick clamp to drive a metal pre-pressure head under an acrylic plate to press down on the electronic component body, while simultaneously a bending metal pressure block presses down to bend the component's leads. This effectively avoids inconsistencies in bending angles and lengths when bending leads of special components, standardizes the bending process and requirements for special components, and improves efficiency and quality.

[0005] Technical solution A through-hole device pin bending device includes a panel, a bracket, and a quick clamp. The quick clamp includes a quick clamp mounting base, a lower pressure rod, and a handle. The quick clamp mounting base is fixed to the bracket by bolts. The first connecting end of the handle passes through the two lugs on the quick clamp mounting base and is fixed by a pin. The second connecting end of the handle is connected to one side of each lug and fixed by pins. The other side of the two lugs is connected to a single lug on the lower pressure rod by a pin. When the handle is turned, the handle rotates around the two lugs on the quick clamp mounting base, and the displacement of the handle causes the lower pressure rod to move up or down. The lower pressure rod has a lower pressure plate fixed to its lower pressure end by screws. A linear bearing is provided on the lower pressure plate. Two first guide posts are symmetrically fixed at one end to the bracket, and the other end passes through the linear bearing to ensure that the lower pressure plate is constrained by the first guide posts to achieve vertical displacement. A carrier plate is fixed on the panel by screws. The carrier plate has a positioning groove and is connected to a metal cover plate by a hinge. The shape of the positioning groove is adapted to the shape of the pin of the through-hole device. The metal cover plate is used to press the pin of the through-hole device. One end of the two second guide posts passes through the working end of the lower pressure plate, and the other end passes through the metal cover plate. A bending metal pressure block is fixed on the working end of the lower pressure plate by screws. Pressing the handle moves the bending metal pressure block downward to bend the pin of the through-hole device.

[0006] Furthermore, it also includes a spring, which is sleeved on the second guide post and is used to restore the displacement after the lower pressure plate is pressed down.

[0007] Furthermore, the positioning grooves are provided in several quantities, which are determined by the number of bends required for the pins of the through-hole device.

[0008] Furthermore, the aforementioned positioning grooves are evenly distributed on the carrier plate and located on the same axis.

[0009] Furthermore, the bracket is provided with a waist-shaped slot. By fixing the bolts at different positions in the waist-shaped slot, the relative height of the quick clamp mounting base on the bracket can be adjusted, thereby adjusting the position of the bending metal pressure block, which is more conducive to bending the pins of through-hole devices.

[0010] Furthermore, the quick clamp is made of stainless steel.

[0011] Furthermore, the metal briquette is made of aluminum alloy.

[0015] Example A through-hole device pin bending device includes a panel 4, a bracket 6, and a quick clamp 1. The quick clamp 1 includes a quick clamp mounting base, a lower pressure rod, and a handle. The quick clamp mounting base on the quick clamp 1 is fixed to the bracket 6 by bolts. The first connecting end of the handle passes through the double ears on the quick clamp mounting base and is fixed with a pin. The second connecting end of the handle is connected to one side of the ear piece on each side and is fixed with a pin. The other side of the two ear pieces is connected to the single ear end on the lower pressure rod by a pin. When the handle is moved up and down, the handle rotates around the double ears on the quick clamp mounting base as an axis, and the displacement of the handle drives the lower pressure rod to move up or down. The lower pressure end of the lower pressure rod is fixed with a lower pressure plate by screws. The lower pressure plate is provided with... A linear bearing 8 is provided, and two first guide posts 5 are symmetrically fixed at one end to the bracket 6, and the other end passes through the linear bearing 8 to ensure that the lower pressure plate is constrained by the first guide posts 5 to achieve vertical displacement; a carrier plate 3 is fixed on the panel 4 by screws, the carrier plate 3 is provided with a positioning groove, and the carrier plate 3 is connected to the metal cover plate 2 by a hinge. The shape of the positioning groove is adapted to the shape of the pin of the through hole device, and the metal cover plate 2 is used to press the pin of the through hole device; two second guide posts 9 pass through the working end of the lower pressure plate at one end and pass through the metal cover plate 2 at the other end; a bending metal pressure block 10 is fixed on the working end of the lower pressure plate by screws. Pressing the handle drives the bending metal pressure block 10 to move down, thereby bending the pin of the through hole device.

[0016] In one embodiment of this utility model, a spring 7 is also included, which is sleeved on the second guide post 9 and is used for displacement recovery after the lower pressure plate is pressed down.

[0017] In one embodiment of this utility model, the positioning groove is provided in several forms, which are determined by the number of pins of the through-hole device that need to be bent as required.

[0018] In one embodiment of this utility model, the plurality of positioning grooves are evenly distributed on the carrier plate 3 and are located on the same axis.

[0019] In one embodiment of this utility model, the bracket 6 is provided with a waist-shaped groove. By fixing the bolts at different positions of the waist-shaped groove, the relative height of the quick clamp mounting seat on the bracket 6 can be adjusted, thereby adjusting the position of the bending metal pressure block 10, which is more conducive to bending the pins of the through-hole device.

[0020] In one embodiment of this utility model, the quick clamp 1 is made of stainless steel.

[0021] In one embodiment of this utility model, the bent metal block is made of aluminum alloy.

[0022] Function and Working Principle. Function: Quickly and accurately places and fixes the PCB and FPC bonding board on the magnetic carrier. Working Principle: Place the electronic components to be bent into the positioning groove of the carrier board 3. Flip the metal cover plate 2 to press the electronic components and expose the leads of the electronic components. Then, put the second guide post 9 with a spring, which passes through the circular hole on the lower pressure plate and the metal cover plate 2. Since the outer diameter of the spring is larger than the outer diameter of the circular hole, the spring can form an elastic deformation on the lower pressure plate and the metal cover plate 2, constraining the lower pressure plate to move only vertically up and down, limiting the travel of the lower pressure plate. After placement, manually press the quick clamp. The quick clamp rotates downward around the pivot, causing the ear to swing. At the same time, the ear, handle, and pressure rod gradually move onto the same axis, making the three in a straight line. This causes the pressure rod to move downward, which in turn drives the pressure plate. The pressure plate drives the metal cover 2, which presses down on the electronic component pins. Continuing to press down causes the bending metal block 10 to bend the pins. The structure is simple, easy to operate, low in cost, and saves time and effort. At the same time, multiple pins can be bent at once, and the bending angle is consistent, improving efficiency.

[0023] This invention primarily involves evaluating the specifications and overall dimensions of the electronic components to be produced to determine the fixture's external dimensions. The material for the positioning base is selected; considering anti-static, wear-resistant, and strength requirements, anti-static bakelite is chosen. A support plate for placing the electronic components is constructed on the positioning base. This plate is made of 304 stainless steel and features hinges; the support plate, bearing pressure, requires high-quality materials. The metal block on the pressure plate platform used for lead bending is also made of 304 stainless steel, as it is prone to wear. The elastic sheet on the quick-pressing head, which provides pre-pressure, is also made of 304 stainless steel. The platform itself is made of acrylic material, with a thickness controlled to 10mm and subjected to hard anodizing. The miniature quick-clamp handle on the upper part of the frame, used for manual pressing, is made of plastic, while the handle body is made of stainless steel. The overall frame of the fixture is made of 10mm thick anti-static bakelite.
