Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCBA board manufacturing technology, and in particular to a handheld blow needle device. Background Technology
[0002] In the PCBA board manufacturing process, small-diameter positioning pins (e.g., approximately 0.7mm in diameter) are typically soldered to specific locations on the board surface. Due to the tiny size of these pins, manual handling and placement are inefficient and prone to errors, necessitating the assistance of handheld feeding devices. In traditional handheld pin-blowing equipment, the positioning pins are fed to a temporary holding block via a rotary feeding device, where they are then blown into the discharge port by air. However, the design of the temporary holding block in such equipment has a significant flaw: a baffle plate is required below it to prevent gas leakage, and an air inlet is provided on the block to release the positioning pins. This structure makes it easy for the gap between the baffle plate and the air inlet to jam the positioning pins, leading to feeding interruptions or equipment malfunctions, severely impacting production efficiency.
[0003] To address the aforementioned issues, existing technologies have attempted to optimize the temporary holding block structure, such as adjusting the baffle position or improving the air hole design, but these methods still struggle to completely eliminate the risk of needle jamming. Furthermore, the air supply path in traditional equipment is complex, and the gas is easily interfered with when blown in through the side air inlet, affecting the stability of the positioning needle's descent. Therefore, there is an urgent need for a handheld needle-blowing device with a simpler structure and more reliable feeding to improve the feeding efficiency and ease of operation of tiny positioning needles. Utility Model Content
[0004] In view of the above-mentioned defects in the prior art, this utility model provides a handheld blow needle device, which aims to solve the problems of positioning needle jamming, material supply interruption and complex gas path affecting the falling stability of the positioning needle caused by the design defects of the temporary block in the existing handheld blow needle device.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a handheld blow needle device, comprising a handheld stand, on which a turntable discharge device and a synchronous blowing device located on one side of the turntable discharge device are configured. The synchronous blowing device includes a synchronous transfer component, a U-shaped synchronous transfer member slidably fitted to the output end of the synchronous transfer component, and an adsorption clamp and a blowing pump respectively disposed on the two extension ends of the U-shaped synchronous transfer member. The adsorption clamp is located on the side closer to the turntable discharge device, and the blowing pump is located on the side away from the turntable discharge device. A discharge port is provided on the handheld stand between the output end of the turntable discharge device and the output end of the synchronous blowing device. A temporary holding block is provided on the side of the synchronous transfer component near the discharge port, directly above the discharge port. The adsorption clamp places the positioning needle on a buffer plate in the temporary holding block, and the blowing pump blows the positioning needle from the buffer plate in the temporary holding block into the discharge port.
[0006] Based on the above, the beneficial effect of a handheld needle blowing device is that it solves the problems of positioning needle jamming, material supply interruption, and the impact of complex gas paths on the falling stability of the positioning needle caused by the design defects of the temporary block in the existing handheld needle blowing device; mainly reflected in:
[0007] 1. This utility model provides a cross-cutting part in the middle of the buffer plate in the temporary block. When the blowing pump is working, the airflow can open the cross-cutting part of the buffer plate, so that the positioning pin can be blown out smoothly. This design avoids the problem that the gap between the baffle and the air inlet hole in the traditional design can easily jam the positioning pin, ensuring that the positioning pin can be smoothly detached from the buffer plate and preventing jamming during the feeding process.
[0008] 2. By combining the buffer plate and the cross-cutting part, this utility model allows the airflow to act more directly and effectively on the positioning pin, ensuring that it falls stably into the discharge port. This not only improves the continuity of material supply, but also greatly reduces the risk of equipment failure, and ensures the continuity and efficiency of production.
[0009] 3. The complex side air inlet design in traditional handheld needle blowing devices is easily affected by external interference, which affects the stability of the positioning needle falling. This utility model simplifies the gas path by working together with the adsorption clamp and the blowing pump, so that the airflow can directly and concentratedly act on the positioning needle on the buffer plate, reducing the influence of external interference factors, ensuring that the positioning needle can fall into the discharge port smoothly and accurately, and improving the stability and reliability of the overall operation.
[0010] 4. Because the gas path is more direct and simpler, the airflow can act on the positioning pin more efficiently, keeping it stable during the transfer process. At the same time, the combined use of the synchronous transfer component and the U-shaped synchronous transfer component ensures that the positioning pin can be accurately transferred from the turntable discharge device to the buffer plate in the temporary block, and finally fall smoothly into the discharge port, further enhancing the stability of the positioning pin's descent.
[0011] Furthermore, the buffer chip has a cross-shaped cut in the middle.
[0012] Based on the above, the beneficial effect of the cross-cutting section is that it allows the airflow to act more concentratedly and directly on the positioning pin, ensuring that it falls stably into the discharge port.
[0013] Furthermore, the synchronous transfer component includes a lifting cylinder, a slide block, and a transfer cylinder. The slide block is disposed at the output end of the lifting cylinder, and the transfer cylinder is disposed on the side of the slide block away from the turntable discharge device. The U-shaped synchronous transfer component is slidably fitted on the track on the slide block, and the output end of the transfer cylinder is connected to the U-shaped synchronous transfer component.
[0014] Based on the above, the beneficial effect of using the lifting cylinder and the slide block together is to achieve precise vertical movement of the U-shaped synchronous transfer component; the beneficial effect of the transfer cylinder is to enable the U-shaped synchronous transfer component to adjust its position in the horizontal direction, ensuring efficient transfer of the positioning pin.
[0015] Furthermore, the rotary discharge device includes a vibrating discharge machine, a discharge baffle, and a rotating discharge mechanism. The discharge baffle is disposed on the vibrating outward moving track at the output end of the vibrating discharge machine, and the rotating discharge mechanism is disposed on the output end of the vibrating outward moving track.
[0016] Based on the above, the beneficial effects of the vibrating discharge machine are that it arranges the positioning pins in an orderly manner through vibration and outputs them along the vibrating outward track, ensuring that the positioning pins remain neatly arranged during the feeding process, avoiding blockage or jamming caused by chaotic accumulation, thereby improving the overall feeding efficiency; the beneficial effects of the discharge baffle are that it effectively controls the flow speed and number of positioning pins, not only preventing too many positioning pins from entering the next process at the same time, but also ensuring that each positioning pin can be accurately delivered to the rotary discharge mechanism.
[0017] Furthermore, the rotary discharge mechanism includes a rotary motor and a rotating disk. The rotating disk is disposed on the output end of the rotary motor. Several positioning pin storage slots are evenly arranged around the rotating disk. Each positioning pin storage slot is driven by the rotary motor to receive material at the output end of the vibrating outward moving track.
[0018] Based on the above, each positioning pin storage slot is driven by a rotary motor to receive materials sequentially at the output end of the vibrating external track. Its beneficial effects are that it greatly improves the material feeding efficiency, reduces the need for manual intervention, and ensures the continuity of the production process.
[0019] Furthermore, the adsorption clamp transfers the positioning pin from the positioning pin storage groove near the discharge port on the rotating disk to the buffer plate in the temporary block.
[0020] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the following description, in conjunction with the accompanying drawings and specific embodiments, will further explain this utility model. Attached Figure Description

Detailed Implementation
[0026] like Figures 1-4 As shown, a handheld blow needle device includes a handheld stand 1, on which a rotary dispensing device 2 and a synchronous blowing device 3 located on one side of the rotary dispensing device 2 are mounted. The synchronous blowing device 3 includes a synchronous transfer assembly 31, a U-shaped synchronous transfer member 32 slidably fitted to the output end of the synchronous transfer assembly 31, and suction clamps 33 and a blowing pump 34 respectively disposed on two extension ends of the U-shaped synchronous transfer member 32. The suction clamps 33 are located on the side closer to the rotary dispensing device 2, and the blowing pump 34 is located on the side closer to the rotary dispensing device 2. On the side away from the turntable discharge device 2, a discharge port 11 is provided on the handheld stand 1 between the output end of the turntable discharge device 2 and the output end of the synchronous blowing device 3. A temporary holding block 35 is provided on the side of the synchronous transfer component 31 near the discharge port 11, located directly above the discharge port 11. The suction clamp 33 places the positioning pin on the buffer plate 351 in the temporary holding block 35. The blowing pump 34 blows the positioning pin from the buffer plate 351 in the temporary holding block 35 into the discharge port 11.
[0027] The buffer chip 351 has a cross-cut section 3511 in the middle.
[0028] The synchronous transfer assembly 31 includes a lifting cylinder 311, a slide block 312, and a transfer cylinder 313. The slide block 312 is disposed at the output end of the lifting cylinder 311, and the transfer cylinder 313 is disposed on the side of the slide block 312 away from the turntable discharge device 2. The U-shaped synchronous transfer member 32 is slidably fitted on the track on the slide block 312, and the output end of the transfer cylinder 313 is connected to the U-shaped synchronous transfer member 32.
[0029] The turntable discharge device 2 includes a vibrating discharge machine 21, a discharge baffle 22, and a rotating discharge mechanism 23. The discharge baffle 22 is disposed on the vibrating outward moving track at the output end of the vibrating discharge machine 21, and the rotating discharge mechanism 23 is disposed on the output end of the vibrating outward moving track.
[0030] The rotary discharge mechanism 23 includes a rotary motor 231 and a rotating disk 232. The rotating disk 232 is disposed on the output end of the rotary motor 231. A plurality of positioning pin storage slots 2321 are evenly arranged around the rotating disk 232. Each positioning pin storage slot 2321 is driven by the rotary motor 231 to receive material at the output end of the vibrating outward moving track.
[0031] The adsorption clamp 33 adsorbs and transfers the positioning pin from the positioning pin storage groove 2321 near the discharge port 11 on the rotating disk 232 to the buffer plate 351 in the temporary block 35.
[0032] In summary, the specific embodiments of this utility model are as follows:
[0033] First, the vibrating discharge machine 21 starts, arranging the positioning pins in an orderly manner onto the vibrating outward moving track through vibration. The discharge baffle 22 corrects the posture of the positioning pins on the outward moving track. The rotary motor 231 drives the rotating disk 232 to rotate intermittently, causing each positioning pin storage slot 2321 to align sequentially with the track output end to receive material. The lifting cylinder 311 drives the slide block 312 to descend, aligning the suction clamp 33 with the positioning pin storage slot 2321 near the discharge port 11. The suction clamp 33 performs negative pressure suction to grab the positioning pins. The transfer cylinder 313 pulls the U-shaped synchronous transfer component 32 to move laterally along the slide rail, transporting the positioning pins above the temporary holding block 35. The lifting cylinder 311 then activates again. The adsorption clamp 33 is lowered to the position of the temporary block 35. The adsorption clamp 33 releases the positioning pin into the buffer plate 351. The positioning pin is embedded in the cross-cutting part 3511 to achieve center positioning. Then, the synchronous transfer component 31 drives the U-shaped synchronous transfer component 32 to reset and return to the initial working position, and drives the slide block 312 to descend again so that the adsorption clamp 33 is aligned with the positioning pin storage groove 2321 near the discharge port 11. At this time, the blowing pump 34 is also aligned with the temporary block 35 and starts to generate directional airflow. The airflow penetrates the cross-cutting part 3511 of the buffer plate 351 and blows the positioning pin vertically off the temporary block 35. The positioning pin is installed on the PCBA board through the discharge port 11.
