Description

Technical Field

[0001] This utility model relates to the field of visual guidance device technology, and in particular to a visual guidance pin device. Background Technology

[0002] Traditional needle insertion is mostly done manually. Workers hold the needle and, relying on visual observation and experience, insert it into the corresponding hole or target position. However, this manual needle insertion method has many drawbacks. On the one hand, with the increasing trend of product miniaturization and micro-miniaturization, and on the other hand, manual needle insertion is slow, making it difficult to meet the high-speed and high-efficiency requirements of large-scale industrial production. Furthermore, the repetitive operation over a long period of time can easily lead to worker fatigue, further increasing the risk of errors.

[0003] To overcome the limitations of manual pin insertion, automated pin insertion technology emerged. Early automated pin insertion devices improved production efficiency to some extent, but due to the lack of precise positioning and guidance methods, they still could not achieve ideal pin insertion results when faced with complex shapes, tiny-sized sockets, and high-precision pin requirements. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a visually guided pin device to solve the problems of low pin insertion efficiency and low accuracy in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0006] A vision-guided pin insertion device includes a horizontal driving device, a vertical driving device disposed on the horizontal driving device, and a vision detection device. The vertical driving device is provided with at least one set of pin insertion assemblies. The pin insertion assembly includes a push pin device, a needle spacer device located below the push pin device, and a needle feeding guide block disposed between the push pin device and the needle spacer device.

[0007] To achieve the above technical solution, during operation, the vision detection device is first activated to acquire and analyze images of the needle plate, accurately locating the target position for needle insertion. At this time, the needle-separating device is closed to prevent the needle from falling. Then, based on the target position of the needle, the horizontal drive device is first driven to move quickly and accurately along the horizontal direction, driving the vertical drive device and the needle insertion assembly to the position above the target. Next, the vertical drive device is activated, driving the needle insertion assembly to the preset height. Then, the ejector device pushes the needle along the needle feeding guide block, while the needle-separating device opens in time to allow the needle to pass smoothly through and be inserted into the insertion plate, completing the needle insertion action. After the needle insertion is completed, the ejector device retracts upward to the initial height, and the needle-separating device closes again, preparing for the next needle insertion operation.

[0008] In one embodiment of the present invention, the needle feeding guide block is provided with a needle guide hole that extends vertically and at least one needle feeding hole that communicates with the needle guide hole.

[0009] To achieve the above technical solution, the needle feed guide block has a through-hole. This design ensures that the needle can be guided into the insert plate along a fixed path. There is at least one needle feed hole, and it is connected to the through-hole. The needle feed hole is mainly for facilitating needle input; that is, the needle can enter the through-hole and then be transported to the designated position along the direction of the through-hole.

[0010] In one embodiment of the present invention, the ejector device includes an ejector cylinder and an ejector rod disposed on the output shaft of the ejector cylinder and capable of passing through the guide needle hole.

[0011] To achieve the above technical solution, the ejector rod is mounted on the output shaft of the ejector cylinder and can pass through the guide hole on the needle feed guide block. The main function of the ejector rod is to push the needle from the guide hole to a predetermined position under the drive of the ejector cylinder to complete the needle insertion action.

[0012] In one embodiment of the present invention, the needle-separating device includes a needle-separating cylinder, two needle-separating blocks disposed on the needle-separating cylinder and capable of closing or opening to each other, and a semi-circular needle-separating tube disposed on the needle-separating blocks.

[0013] To achieve the above technical solution, the needle-separating cylinder is the power source for the needle-separating device, responsible for driving the two needle-separating blocks to open and close. When it is necessary to clamp the needle, the needle-separating cylinder pushes the needle-separating blocks to close; when it is necessary to release the needle, it separates the needle-separating blocks. Each needle-separating block is equipped with a semi-circular needle-separating tube. When the needle-separating blocks close, the two semi-circular needle-separating tubes connect to form a complete circular tube, which is used to clamp the needle and ensure that the needle will not shift or fall off during transmission.

[0014] In one embodiment of the present invention, the semi-circular needle tube includes a large-diameter portion, a small-diameter portion, a needle-separating portion that gradually transitions from the large-diameter portion to the small-diameter portion, and an inlet portion with a diameter larger than the large-diameter portion and gradually converging toward the large-diameter portion.

[0015] To achieve the above technical solution, the design of the inlet section is to facilitate the smooth entry of the needle into the semi-circular needle separator tube. Its diameter is larger than that of the large-diameter section and gradually narrows towards the large-diameter section to form a guiding function. The diameter of the large-diameter section is larger than that of the needle insertion, providing a spacious area. When the needle separator blocks close, the needle separator sections of the two semi-circular needle separator tubes come into contact with each other to form a gradually narrowing channel, which accurately positions and isolates the needle insertion, preventing the needle from falling or moving further. The small-diameter section is located at the end of the semi-circular needle separator tube. Its smaller diameter can limit the shaking and swaying of the needle insertion, keeping the needle stable while waiting for insertion and improving the accuracy of needle insertion.

[0016] In one embodiment of the present invention, the horizontal drive device includes a linear motor, a slide block slidably disposed on the linear motor, and a mounting plate disposed on the slide block.

[0017] To achieve the above technical solution, the mounting plate is fixed on the slide and moves as the slide moves. The mounting plate is used to drive the vertical drive device and the pin insertion assembly to move horizontally, enabling the pin insertion device to perform pin insertion operations at different positions, thereby completing the pin insertion task at different target positions.

[0018] In one embodiment of the present invention, the vertical driving device includes a slide cylinder mounted on the mounting plate and a vertical plate mounted on the slide seat of the slide cylinder. The vertical plate is provided with the ejector pin device, the needle feeding guide block and the needle separating device from top to bottom.

[0019] To achieve the above technical solution, the slide cylinder controls the lifting and lowering of the slide base to achieve precise position adjustment. A vertical plate is fixed on the slide base. The vertical plate serves as a support structure and is used to install key components such as the ejector pin device, the needle feeding guide block, and the needle spacing device, ensuring that these components can move synchronously in the vertical direction.

[0020] In one embodiment of the present invention, the visual inspection device includes a connecting frame disposed on the mounting plate, an industrial camera disposed on the connecting frame, and an annular light source disposed on the connecting frame and located below the industrial camera.

[0021] To achieve the above technical solution, the connecting frame is fixed on the mounting plate and serves as a support structure for mounting the industrial camera and the ring light source. The industrial camera is the core component of visual inspection and is responsible for capturing images of the target area. The ring light source is placed below the industrial camera to provide uniform illumination for shooting.

[0022] As described above, the visually guided pin insertion device of this utility model has the following beneficial effects: Utilizing an industrial camera and ring light source in the visual inspection device, high-definition images of the insertion holes are acquired and precisely analyzed, obtaining the accurate position information of the insertion holes in real time, with an accuracy down to the micrometer level. Furthermore, in conjunction with the linear motor of the horizontal drive device and the slide cylinder of the vertical drive device, the pin is accurately inserted into extremely small and complex insertion holes. The pin insertion accuracy is several times higher than that of traditional pin insertion methods, greatly reducing the scrap rate and ensuring the stability of product quality.

[0023] The entire pin insertion process is highly automated, requiring no manual operation. After rapid positioning by the vision inspection device, the horizontal and vertical drive devices respond quickly, driving the pin insertion assembly to complete the pin insertion action. The operation time for a single pin is significantly reduced compared to manual pin insertion, and continuous, uninterrupted operation is possible, significantly increasing the number of pins inserted per unit time. The pin-separating cylinder of the pin-separating device drives the pin-separating block to open and close precisely, effectively preventing accidental pin drops when not in the insertion state and reducing the risk of equipment failure.

[0032] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Please see Figures 1 to 6This utility model provides a visually guided pin insertion device, including a horizontal driving device, a vertical driving device and a visual detection device disposed on the horizontal driving device, wherein the vertical driving device is provided with at least one set of pin insertion assemblies; the pin insertion assembly includes a push pin device, a needle spacer device located below the push pin device, and a needle feeding guide block 1 disposed between the push pin device and the needle spacer device.

[0034] During operation, the vision detection device is first activated to acquire and analyze images of the needle plate, accurately locating the target position for needle insertion. At this time, the needle-separating device is closed to prevent the needle from falling. Then, based on the target position of the needle, the horizontal drive device is first driven to move quickly and accurately along the horizontal direction, driving the vertical drive device and the needle insertion assembly to the position above the target. Next, the vertical drive device is activated, driving the needle insertion assembly to the preset height. Then, the ejector device pushes the needle along the needle feeding guide block 1, while the needle-separating device opens in time to allow the needle to pass smoothly through and be inserted into the insertion plate, completing the needle insertion action. After the needle insertion is completed, the ejector device retracts upward to the initial height, and the needle-separating device closes again, preparing for the next needle insertion operation.

[0035] By using a vision inspection device to obtain accurate target position information in real time, and in conjunction with the high-precision motion control of the horizontal and vertical drive devices, the needle can be accurately inserted into an extremely small insert plate, which greatly improves the accuracy of the needle insertion and reduces the scrap rate.

[0036] The needle feeding guide block 1 has a vertically penetrating needle guide hole 2 and at least one needle feeding hole 3 connected to the needle guide hole 2. The vertically penetrating needle guide hole 2 on the needle feeding guide block 1 is designed to ensure that the needle can be guided into the insert plate along a fixed path. There is at least one needle feeding hole 3, and it is connected to the needle guide hole 2. The existence of the needle feeding hole 3 is mainly to facilitate needle input; that is, the needle can enter the needle guide hole 2 through the needle feeding hole 3 and then be conveyed to the designated position along the direction of the needle guide hole 2.

[0037] The ejector pin device includes an ejector pin cylinder 4 and an ejector pin rod 5 mounted on the output shaft of the ejector pin cylinder 4 and capable of passing through the guide pin hole 2. The ejector pin rod 5 is mounted on the output shaft of the ejector pin cylinder 4 and can pass through the guide pin hole 2 on the needle feed guide block 1. The main function of the ejector pin rod 5 is to push the needle from the guide pin hole 2 to a predetermined position to complete the needle insertion action under the drive of the ejector pin cylinder 4.

[0038] The needle-separating device includes a needle-separating cylinder 6, two needle-separating blocks 7 mounted on the needle-separating cylinder 6 and capable of closing or opening, and a semi-circular needle-separating tube 8 mounted on the needle-separating blocks 7. The needle-separating cylinder 6 is the power source for the needle-separating device, responsible for driving the two needle-separating blocks 7 to open and close. When it is necessary to clamp the needle, the needle-separating cylinder 6 pushes the needle-separating blocks 7 to close; when it is necessary to release the needle, it opens the needle-separating blocks 7. Each needle-separating block 7 is equipped with a semi-circular needle-separating tube 8. When the needle-separating blocks 7 are closed, the two semi-circular needle-separating tubes 8 connect to form a complete circular tube, used to clamp the needle and ensure that the needle does not shift or fall off during transmission.

[0039] The semicircular needle separator tube 8 includes a large-diameter section 81, a small-diameter section 82, a needle separator section 83 that gradually transitions from the large-diameter section 81 to the small-diameter section 82, and an inlet section 84 with a diameter larger than the large-diameter section 81 and gradually converging towards the large-diameter section 81. The inlet section 84 is designed to facilitate the smooth entry of the needle into the semicircular needle separator tube 8. Its diameter is larger than the large-diameter section 81 and gradually converges towards the large-diameter section 81, forming a guiding function. The large-diameter section 81 has a larger diameter than the needle, providing ample space. When the needle separator block 7 closes, the needle separator sections 83 of the two semicircular needle separator tubes 8 come together to form a gradually converging channel, accurately positioning and isolating the needle, preventing the needle from falling or moving further. The small-diameter section 82 is located at the end of the semicircular needle separator tube 8. Its smaller diameter can limit the shaking and swaying of the needle, keeping the needle stable while waiting for insertion and improving the accuracy of insertion.

[0040] The horizontal drive device includes a linear motor 9, a slide block 10 slidably mounted on the linear motor 9, and a mounting plate 11 mounted on the slide block 10. The mounting plate is fixed to the slide block 10 and moves as the slide block 10 moves. The mounting plate 11 is used to drive the vertical drive device and the pin insertion assembly to move horizontally, enabling the pin insertion device to perform pin insertion operations at different positions, thereby completing the pin insertion task at different target positions.

[0041] The vertical drive device includes a slide cylinder 12 mounted on the mounting plate 11 and a vertical plate 13 mounted on the slide base of the slide cylinder 12. The vertical plate 13, from top to bottom, is equipped with the ejector pin device, the needle feed guide block 1, and the needle separator device. The slide cylinder 12 achieves precise position adjustment by controlling the lifting and lowering of the slide base. The vertical plate 13 is fixed on the slide base. The vertical plate 13 serves as a support structure for mounting key components such as the ejector pin device, the needle feed guide block 1, and the needle separator device, ensuring that these components can move synchronously in the vertical direction.

[0042] The visual inspection device includes a connecting frame 14 mounted on the mounting plate 11, an industrial camera 15 mounted on the connecting frame 14, and a ring light source 16 mounted on the connecting frame 14 and located below the industrial camera 15. The connecting frame 14 is fixed to the mounting plate 11 and serves as a support structure for mounting the industrial camera 15 and the ring light source 16. The industrial camera 15 is the core component of the visual inspection device, responsible for capturing images of the target area (such as the location of a socket). The ring light source 16 is located below the industrial camera 15 to provide uniform illumination for shooting.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
