Description

Technical Field

[0001] This utility model relates to the technical field of SMT (Surface Mount Technology), and in particular to a stud SMT placement device. Background Technology

[0002] SMT, or Surface Mount Technology, is an automated assembly technology that directly mounts electronic components onto the surface of a printed circuit board (PCB). Its core processes include solder paste printing, component placement, and reflow soldering. This technology uses high-precision pick-and-place machines to achieve high-speed, precise positioning of miniature components and utilizes reflow soldering to melt the solder paste and form reliable electrical connections. It boasts advantages such as high assembly density, high production efficiency, and low cost, and has become the mainstream process in modern electronic product manufacturing, widely used in consumer electronics, communication equipment, and automotive electronics.

[0003] Studs on PCBs primarily serve a dual function: mechanical fixation and electrical connection. Mechanically, they act as structural support points to secure the PCB, such as by tightening with housing screws, connecting other modules or heat sinks, and enhancing overall structural stability. Electrically, they can serve as grounding terminals or conductive paths, and some designs achieve circuit continuity through soldering. Their selection must consider installation strength, vibration resistance, and process compatibility, such as reflow soldering / press-fitting, making them crucial components for connecting hardware and circuits in electronic devices.

[0004] Based on this, Chinese patent document CN202475952U discloses a PCB board copper stud pressing fixture, which includes: a base, a frame, and a manual pressing device. The frame is fixedly mounted on the base, and the manual pressing device is fixedly mounted on the frame. If the PCB board copper stud pressing fixture disclosed in this technical solution is adopted, it can easily press the copper studs onto the PCB board before wave soldering. In this way, the copper studs and the PCB board are not only mechanically connected through the solder pads, but also have an interference fit connection, making the connection more reliable and effectively preventing pull-out and damage to the solder pads on the PCB board.

[0005] However, existing PCB copper stud fixtures have a technical problem that easily leads to PCB deformation. Specifically, during the process of pressing copper studs onto the PCB using existing fixtures, the copper studs create localized point-like stress points on the PCB, and the resulting overall PCB deformation is usually irreversible. Therefore, a better process to reduce PCB deformation is to use SMT (Surface Mount Technology) for stud placement, which mainly includes the following steps: First, solder paste is precisely printed on the PCB pads using a solder paste printer; then, a high-precision pick-and-place machine accurately places the stud components onto the pads; next, a reflow oven is used to heat the solder paste, melting it and forming reliable solder joints; finally, optical inspection or functional testing is performed to ensure placement quality and electrical performance. However, existing pick-and-place machines typically have a fixed mechanism, and the stud's orientation cannot be changed in real time during placement, often leading to inaccurate stud positioning.

[0025] Please refer to the following: Figures 1 to 4 The present invention relates to a stud SMT placement device, comprising: a support frame 1, a placement head 2, a limiting guide part 3, a vertical drive mechanism 4, and a rotary drive mechanism 5; two placement heads 2 are movably disposed on the side of the support frame 1, and the lower part of each placement head 2 is movably connected to one of the limiting guide parts 3; two vertical drive mechanisms 4 are disposed adjacent to the support frame 1, and each vertical drive mechanism 4 is driven connected to one of the limiting guide parts 3; the rotary drive mechanism 5 is disposed on the upper part of the support frame 1, and the rotary drive mechanism 5 is driven connected to the two placement heads 2.

[0026] Specifically, when the stud SMT placement device of this utility model is in operation, the two vertical drive mechanisms 4 can drive the two limiting guide parts 3 to make the two placement heads 2 move independently downward or upward. When the placement head 2 moves downward, it can pick up the stud or other materials to be placed and hold the picked-up materials so that they are driven by the external feeding mechanism to be carried above the PCB part to be attached. Then, the vertical drive mechanism 4 drives the limiting guide parts 3 to drive the placement head 2 downward, thereby performing placement processing on the stud or other materials. In particular, when placing stud or other materials, the rotary drive mechanism 5 can drive the placement head 2 to rotate to adjust the posture of the picked-up materials so that the materials can be adjusted to a preset angle or posture before being attached. Therefore, this utility model of stud SMT placement device can rotate and adjust the posture of materials such as studs during placement processing, so that the materials being placed can complete the placement process in a preset posture. This avoids the defect of existing technology that requires operators to manually adjust the posture of materials such as studs during placement processing. Therefore, this utility model of stud SMT placement device solves the technical problem of how to improve the placement efficiency of studs.

[0027] Furthermore, each of the patch heads 2 has an adsorption part 201, a rod body 202, a turntable connecting part 203, a spring limiting part 204, and a spring 205; the adsorption part 201 is disposed at the lower part of the rod body 202, the turntable connecting part 203 is connected to the adsorption part 201 and is movably sleeved on the rod body 202, the spring limiting part 204 is sleeved on the rod body 202 above the turntable connecting part 203, and the spring 205 is disposed between the turntable connecting part 203 and the spring limiting part 204 and is movably sleeved on the rod body 202.

[0028] Furthermore, each of the limiting guide parts 3 has a vertical guide rail 301, a vertical reciprocating seat 302, a rotating shaft 303, and a roller 304; the vertical guide rail 301 is disposed on the side of the support frame 1, the vertical reciprocating seat 302 is movably connected to the side of the vertical guide rail 301, four rotating shafts 303 are evenly distributed on the side of the vertical reciprocating seat 302, and a roller 304 is movably connected to the end of each rotating shaft 303; two horizontally arranged rollers 304 are disposed opposite to each other on both sides of the rod body 202, and two vertically arranged rollers 304 are disposed opposite to each other on the upper and lower sides of the turntable connecting part 203.

[0029] Furthermore, each of the vertical drive mechanisms 4 includes a vertical drive motor 401, a vertical output shaft 402, a vertical output wheel 403, a vertical driven wheel 404, and a vertical transmission belt 405. The vertical drive motor 401 is disposed on the lower part of the side of the support frame 1, and the vertical drive motor 401 is drivenly connected to the vertical output shaft 402. The vertical output wheel 403 is connected to the vertical output shaft 402. The vertical output wheel 403 is movably disposed on the lower part of the side of the support frame 1, and the vertical driven wheel 404 is disposed on the upper part of the same side of the support frame 1 relative to the vertical output wheel 403. The vertical transmission belt 405 connects the vertical output wheel 403 and the vertical driven wheel 404 respectively. The vertical reciprocating seat 302 is connected to the side of the vertical transmission belt 405.

[0030] Specifically, after being energized, the vertical drive motor 401 can drive the vertical output shaft 402 to rotate the vertical output wheel 403. When the vertical output wheel 403 rotates, it can drive the vertical transmission belt 405 to reciprocate between the vertical output wheel 403 and the vertical driven wheel 404. Thus, the vertical transmission belt 405 can drive the vertical reciprocating seat 302 to reciprocate up or down along the side of the vertical guide rail 301. The roller 304 provided on the side of the vertical reciprocating seat 302 can be limited and clamped from the top, bottom, left and right of the turntable connection part 203. Thus, the roller 304 drives the turntable connection part 203 to drive the patch head 2 to move upward through the transmission of the spring 205 and the spring limiting part 204; or, under the transmission of the adsorption part 201, drive the patch head 2 to move downward.

[0031] Furthermore, the rotary drive mechanism 5 includes a rotary drive motor 501, a rotary output shaft 502, a rotary output wheel 503, a rotary driven wheel 504, a rotary transmission belt 505, and a rotary bearing section 506. The rotary drive motor 501 is disposed on the upper side of the support frame 1, and the rotary drive motor 501 is drivenly connected to the rotary output shaft 502. The rotary output wheel 503 is connected to the rotary output shaft 502. Each rod 202 is correspondingly and movably connected to a rotary driven wheel 504, and the rotary transmission belt 505 sequentially connects each rotary driven wheel 504 and the rotary output wheel 503. Two rotary bearing sections 506 are disposed adjacently on the upper part of the support frame 1, and each rotary bearing section 506 is movably sleeved with a rod 202.

[0032] Specifically, after the rotary drive motor 501 is energized and started, it can drive the rotary output shaft 502 to rotate, thereby driving the rotary output wheel 503 to rotate. Under the action of the power output by the rotary output wheel 503, the rotary transmission belt 505 transmits power to each of the rotary driven wheels 504, thereby driving each of the rotary driven wheels 504 to rotate. In turn, the rotary driven wheels 504 drive each of the rods 202 to rotate. When the rod 202 rotates, its upper part is rotated and supported by the rotary bearing part 506; its lower part is rotated and supported by the four rollers 304 provided on the side of the vertical reciprocating seat 302. This is because the rollers 304 only limit the up and down movement of the rod 202 and do not interfere with the rotation of the rod 202.

[0033] In summary, the stud SMT placement device of this utility model is provided with a support frame 1, a placement head 2, a limiting guide part 3, a vertical drive mechanism 4, and a rotary drive mechanism 5. Two placement heads 2 are movably arranged on the side of the support frame 1, and the lower part of each placement head 2 is movably connected to a limiting guide part 3. Two vertical drive mechanisms 4 are arranged adjacent to each other on the support frame 1, and each vertical drive mechanism 4 is drivenly connected to a limiting guide part 3. The rotary drive mechanism 5 is located on the upper part of the support frame 1 and is drivenly connected to the two placement heads 2. This stud SMT placement device can rotate and adjust the posture of materials such as studs during placement processing, so that the materials being placed can complete the placement process in a preset posture. This avoids the defect of existing technologies requiring manual adjustment of the material posture by operators during stud placement processing. Therefore, this stud SMT placement device solves the technical problem of how to improve the placement efficiency of studs.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
