Description

Technical Field

[0001] This invention relates to the field of sorting technology, and more particularly to a needle-punching sorting device. Background Technology

[0002] In current needle punching sorting equipment, the grains on the lower blue film are pushed onto the upper blue film by the pin of the needle punching device. However, because the upper blue film is relatively soft, when there are many grains on the upper blue film, the middle will be concave, which affects the accuracy and speed of subsequent needle punching. This means that needle punching sorting can only use a smaller size blue film as the upper blue film to sort the grains, and it is not possible to use a larger size blue film as the upper blue film to sort the grains.

[0003] In view of this, there is a need to design a needle-punching sorting device that can use a larger-sized blue film to sort grains.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Summary of the Invention

[0047] In view of the deficiencies of existing needle-punching sorting equipment, the applicant, based on years of practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theoretical principles, actively researched and innovated in order to create a technology that could solve the deficiencies of the existing technology and make the needle-punching sorting equipment more practical. After continuous research, design, and repeated prototype production and improvement, this invention with real practical value was finally created.

[0048] Please refer to Figures 1 to 6 This invention provides a needle-punching sorting device, including a visual inspection device 1, a needle device 2, a lower blue film fixing device 3 for tightening the lower blue film 100, and an upper blue film fixing device 4 for tightening the upper blue film 200. The needle-punching sorting device also includes a support frame, on which the visual inspection device 1, the needle device 2, the lower blue film fixing device 3, and the upper blue film fixing device 4 are all mounted.

[0049] The visual inspection device 1 is installed on the top side of the lower blue film fixing device 3 for photographing and positioning the chips on the lower blue film 100. The visual inspection device 1 includes a CCD camera 11, a transparent positioning plate 12 installed on the bottom side of the CCD camera 11, and a detection lifting device 13 for raising and lowering the CCD camera 11. The transparent positioning plate 12 is installed on the CCD camera 11 and parallel to the horizontal plane. In actual production, the CCD camera 11 photographs and positions the chips on the lower blue film 100 through the transparent positioning plate 12 and the upper blue film 200, thereby enabling the ejector device 2 to accurately eject the chips onto the upper blue film 200. It should be noted that the ejector device 2 and the visual inspection device 1 are electrically connected, allowing the visual inspection device 1 to transmit the chip position information to the ejector device 2, which then ejects the chips according to their position.

[0050] The detection lifting device 13 drives the transparent positioning plate 12 and the CCD camera 11 to rise and fall synchronously, so that the bottom surface of the transparent positioning plate 12 is attached to the top surface of the upper blue film 200; the ejector pin device 2 is installed on one side of the bottom of the lower blue film fixing device 3, which can push the crystals on the lower blue film 100 to the upper blue film 200 that is attached to the transparent positioning plate 12.

[0051] It should be noted that the bottom surface of the transparent positioning plate 12 is parallel to the horizontal plane, and the bottom surface of the visual inspection device 1 and the top surface of the upper blue film 200 are in close contact. The adhesion between them effectively maintains the position of the upper blue film 200, preventing the middle of the upper blue film 200 from sagging or concave. This keeps the transfer area of ​​the larger upper blue film 200 horizontal, allowing it to accurately adsorb more grains. The transfer area refers to the area used for adsorbing grains.

[0052] The larger-sized blue membrane 200 can be applied to actual needle sorting equipment, which can improve the efficiency of sorting and transfer, as well as the production efficiency of subsequent processes.

[0053] Optionally, the lower blue film fixing device 3 includes a crystal expansion ring 31, which expands the film and thus tightens the lower blue film 100. The crystal expansion ring 31 includes a ring body 311 and a plurality of bearings 312. The bearings 312 are mounted on the top of the ring body 311 and arranged in a circumferential array around the center line of the ring body 311. The center line of the bearings 312 is perpendicular to the radial direction of the ring body 311 and perpendicular to the center line of the ring body 311, and the top of the bearings 312 protrudes from the top surface of the ring body 311. During the tightening of the lower blue film 100, the bearings 312 rotate outward; when the bearings 312 rotate inward, the tightened lower blue film 100 gradually relaxes. In this embodiment, the clever use of the structure of the ring body 311 and the plurality of bearings 312 combined together allows the lower blue film 100 to move more smoothly during the tightening and expansion process, and avoids friction between the lower blue film 100 and the top surface of the ring body 311, effectively preventing the upper blue film 200 from tearing.

[0054] Optionally, the top of the ring 311 is formed with several protrusions 3101 at intervals. A rotating shaft connects two adjacent protrusions 3101, and a bearing 312 is mounted on each rotating shaft between two adjacent protrusions 3101. The highest point of each protrusion 3101 is not higher than the highest point of each bearing 312. The several protrusions 3101 at intervals define the installation position of the bearings 312, preventing the installation positions of two adjacent bearings 312 from being too far apart or too close, which would affect the flatness of the lower blue film 100 under tension. The bearings 312 are arranged in a circumferential array, resulting in a more uniform distribution and thus better tension and flatness of the lower blue film 100.

[0055] Optionally, the lower blue film fixing device 3 further includes a film expansion lifting assembly for driving the expansion ring 31 to rise and fall, and a male and female ring 32 for pressing the lower blue film 100 onto the expansion ring 31. Specifically, the lower blue film 100 includes a film body and a crystal ring connected to the edge of the film body. When the crystal ring is limited and pressed by the male and female ring 32, the expansion ring 31 rises (at this time, the bearing 312 rotates outward) to tighten the middle part of the lower blue film 100.

[0056] Optionally, the lower blue film fixing device 3 further includes a mother-daughter ring 32 for pressing the lower blue film 100 onto the crystal expansion ring 31 and a film lifting device for driving the mother-daughter ring 32 to rise and fall. Specifically, the lower blue film 100 includes a film body and a crystal ring connected to the edge of the film body. In this embodiment, by driving the mother-daughter ring 32 down (at this time, the bearing 312 rotates outward), the crystal ring slides downward along the outer periphery of the ring body 311, thereby tightening the middle part of the lower blue film 100.

[0057] Optionally, the needle-punching sorting device also includes a support frame; the lower blue film fixing device 3 also includes a bottom support ring 33 and a rotating device 34 for driving the bottom support ring 33 to rotate, and the crystal expansion ring 31 is mounted on the bottom support ring 33; the rotating device 34 includes a drive motor, a drive synchronous pulley mounted on the drive motor, a rack 343 mounted on the bottom support ring 33, and a synchronous belt 344 connecting the rack 343 and the drive synchronous pulley.

[0058] Specifically, when the lower blue film 100 is first placed into the lower blue film fixing device 3, the rotation angle of the lower blue film 100 may deviate from the required angle of the ejector pin. At this time, the drive motor can drive the active synchronous pulley to rotate, thereby driving the bottom support ring 33 to rotate, thus rotating the bottom support ring 33 to a suitable angle. That is, the rotating device 34 can finely adjust the rotation angle of the lower blue film 100 to meet the needs of actual production.

[0059] Optionally, the upper blue film fixing device 4 includes a horizontal slide rail 41, a receiving plate 42 slidably mounted on the horizontal slide rail 41, and a horizontal driving device 43 for driving the receiving plate 42 to move along the horizontal slide rail 41; the receiving plate 42 is provided with a clamping device for fixing the upper blue film 200. Similarly, the upper blue film 200 includes a film body and a crystal ring connected to the edge of the film body. The clamping device can fix the upper blue film 200 by fixing and clamping the crystal ring.

[0060] Optionally, the ejector device 2 includes an ejector head 21 and an ejector lifting device 22 for driving the ejector head 21 to rise and fall. The ejector lifting device 22 drives the ejector head 21 to rise to a suitable height at a suitable position, thereby transferring the grains on the lower blue film 100 to the upper blue film 200.

[0061] Optionally, the visual inspection device 1 also includes a connecting frame 14 connected to the CCD camera 11; a transparent positioning plate 12 is detachably installed at the bottom end of the connecting frame 14, and the connecting frame 14 is provided with a detection channel for the CCD camera 11 to detect the crystals. In actual production, operators can replace transparent positioning plates 12 of different diameters to meet the sorting needs of blue films 200 of different diameters.

[0062] Optionally, the top of the ring body 311 is provided with an annular groove 301, which surrounds the center line of the ring body 311 and penetrates each protrusion 3101. An annular shaft 302 is installed in the annular groove 301, and the shaft segment of the annular shaft 302 between two adjacent protrusions 3101 is cylindrical. The bearing 312 is rotatably mounted on the cylindrical shaft segment. In this embodiment, after the bearings 312 are strung on the annular shaft 302, all bearings 312 can be installed on the ring body 311 at once, which greatly simplifies the installation work and effectively ensures the installation accuracy. It should be noted that the section between two adjacent cylindrical shaft segments is a connecting section, and the maximum diameter of the connecting section is smaller than the diameter of the cylindrical shaft segment, thereby facilitating the sliding of the bearing 312 onto the appropriate cylindrical shaft segment. It should also be noted that the annular shaft 302 is initially disconnected at both ends. After all bearings 312 are installed onto the cylindrical shaft segment, the ends of the annular shaft 302 are aligned. Furthermore, the cross-section of the connecting shaft segment can be triangular, and the protrusion 3101 has a triangular groove that matches the end of the connecting shaft, which further improves positioning accuracy.

[0063] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
