Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit board processing tooling, in particular to a PCBA component pin bending and forming tooling. Background Art

[0002] PCBA components, or printed circuit board assembly (PCB), are crucial components of electronic devices. These components are assembled and soldered onto a printed circuit board (PCB) through a specific process, forming a complete electronic system.

[0003] PCBA components typically include: electronic components such as resistors, capacitors, inductors, diodes, transistors or integrated circuits; in addition, there are sensors, transformers, switches or relays. The manufacturing process of PCBA components involves multiple steps, including PCB design, manufacturing, component placement, welding and testing. When connecting electronic components to the PCB by welding, it is usually necessary to process the pins of the electronic components, such as bending and cutting. This is because the pins of standard electronic components are usually straight and equal in length when they are received. They cannot meet all PCB layout requirements and often need to be bent and processed.

[0004] Based on this, Chinese patent CN220532830U discloses an electronic component pin bending jig, which includes a base, a bottom plate fixedly connected to the left side of the top of the base, a movable rod slidably connected to the front side of the top of the bottom plate, a gear meshing link at the front end of the movable rod, and a rotating rod fixedly connected to the inner diameter of the gear. In the technical solution disclosed in this patent, when it is necessary to bend the pin of an electronic component, the electronic component needs to be fixed and clamped first, and the handle is moved backward, and the movement of the handle drives the rotating rod to rotate, and the rotating rod drives the gear to rotate, and the gear drives the movable rod to move, and the movable plate and the fixed plate are driven downward as a whole by the movement of the movable rod, thereby achieving the fixation of the electronic component, facilitating the clamping and fixation of the electronic component during bending, and preventing the electronic component from shaking and being damaged. At the same time, a plurality of bending grooves are provided above the fixed plate, which can be applied to a variety of different electronic components and convenient for fixing different electronic components.

[0005] However, the aforementioned electronic component pin bending jig still suffers from the technical problem of being time-consuming and labor-intensive to operate. Specifically, the technical solution disclosed in the existing patent primarily relies on the operator moving a handle backward, which in turn rotates a rotating rod, which in turn rotates a gear, which in turn moves a movable rod, which in turn moves the movable plate and fixed plate downward as a whole, thereby achieving the fixing and bending of the electronic component. In mass production operations, this not only consumes time and effort for operators, but also affects the bending yield of the product due to fatigue. Utility Model Content

[0027] Please also refer to Figures 1 to 3 The utility model provides a PCBA component pin bending and forming tooling, which includes: a base 1, a limiting jig 2, a bending execution structure 3, a bending drive mechanism 4, a stand guide structure 5 and a vertical action mechanism 6; the limiting jig 2 is arranged on the base 1, the bending execution structure 3 and the bending drive mechanism 4 are both adjacent to the limiting jig and arranged on the base 1, and the bending drive mechanism 4 is driven and connected to the bending execution structure 3; the stand guide structure 5 is arranged above the limiting jig 2, the vertical action mechanism 6 is arranged above the stand guide structure 5, and the vertical action mechanism 6 is arranged opposite to the limiting jig 2.

[0028] Specifically, when a PCBA component pin bending and forming tooling of the present invention is in the working process, the electronic component to be bent is automatically conveyed or placed on the limiting jig 2, and the limiting jig 2 performs preliminary limiting placement on the electronic component; the vertical action mechanism 6 first moves close to the limiting jig 2 along the guidance of the vertical frame guide structure 5 to limit and clamp the electronic component placed therein; then, the bending drive mechanism 4 is started and drives the bending execution structure 3 to perform a bending action to bend the pins of the limited electronic components until the pins of the component are bent to a preset angle and maintained for a preset time to prevent them from rebounding and deforming; the bending drive mechanism 4 drives the bending execution structure 3 to reset and the vertical action mechanism 6 to reset; finally, the electronic components that have completed the bending process are taken away and flow into the next workstation. It can be seen that the bending drive mechanism 4, the bending execution structure 3 and the vertical action mechanism 6 of the PCBA component pin bending and forming tool of the present invention can automatically bend the pins of the electronic components according to a preset program, saving the manpower input of the operator.

[0029] Furthermore, the positioning jig 2 comprises a body receiving seat 201, a body limiting block 202, a pin positioning seat 203, and pin guide grooves 204; the body receiving seat 201 is disposed on the base 1, and the body limiting block 202 is movably disposed on the body receiving seat 201; the pin positioning seat 203 is disposed on the adjacent side of the body receiving seat 201, and a plurality of pin guide grooves 204 are evenly distributed on the pin positioning seat 203. Specifically, when the electronic component to be processed is placed in the positioning jig 2, its body portion can be placed in the body receiving seat 201 so that the body limiting block 202 can limit it; and the pin portion of the component is placed on the pin positioning seat 203, and then each pin is placed one by one in a corresponding pin guide groove 204.

[0030] Furthermore, the bending execution structure 3 has a bending swing plate 301, a bending connecting frame 302, a swing shaft structure 303 and a swing support seat 304; the bending swing plate 301 is movably connected to the end side of the pin positioning seat 203, and the bending swing plate 301 is connected to the bending connecting frame 302; the two swing shaft structures 303 are respectively arranged on the two side surfaces of the bending swing plate 301, and each swing shaft structure 303 is correspondingly arranged in one of the swing support seats 304, and the two swing support seats 304 are relatively arranged on the base 1.

[0031] Furthermore, the bending drive mechanism 4 has a gear structure 401, a rack structure 402, a bending telescopic rod 403 and a bending drive cylinder 404; the gear structure 401 is connected to the swing shaft structure 303 on one side of the bending connecting frame 302, the gear structure 401 is meshed and connected with the rack structure 402, and the bending telescopic rod 403 is connected to the rack structure 402; the bending drive cylinder 404 is driven and connected to the bending telescopic rod 403, and the bending drive cylinder 404 is arranged on the base 1.

[0032] Specifically, when bending the pins of an electronic component, the bending drive cylinder 404 is activated, driving the bending telescopic rod 403 to extend, causing the rack structure 402 to advance. The rack structure 402 then drives the gear structure 401 to rotate, thereby converting linear motion into rotational swinging motion. The gear structure 401 can then drive one of the swinging shaft structures 303 to rotate, which in turn causes the bending connecting frame 302 to swing the bending swing plate 301 along the end side of the pin positioning seat 203, thereby bending the pins of the electronic component placed in the pin guide groove 204 to a predetermined angle. After completing a single bending operation, the bending drive cylinder 404 drives the components to reset.

[0033] Furthermore, the stand guide structure 5 has a supporting stand 501 and a vertical guide rail 502 ; the supporting stand 501 is fixedly connected to the base 1 , and the vertical guide rail 502 is arranged on the side of the supporting stand 501 .

[0035] Specifically, before the bending mechanism 3 performs a bending operation, the vertical drive cylinder 604 is first activated to extend the vertical telescopic rod 603, which in turn drives the vertical reciprocating block 602 downward along the vertical guide rail 502 until the abutment stop block 601 secures the pin of the electronic component placed in the pin guide groove 204. Only then does the bending mechanism 3 perform the bending operation on the pin. After completing a single processing step, the vertical drive cylinder 604 resets the components.
