Description

Technical Field

[0001] This utility model relates to the field of yarn spindle production technology, specifically a yarn spindle packaging and stacking device with a machine vision positioning structure. Background Technology

[0002] Spindles are the main components of a spinning machine, used to twist fibers into yarn and wind them into a certain shape. Their quantity and specifications affect the thickness, quality and spinning efficiency of the yarn. During the production process, packaging can protect spindles from damage, keep them clean and facilitate identification and classification, while stacking can effectively save space and facilitate management.

[0003] In current yarn production, packaging and stacking devices are used for efficient production. Machine vision positioning is used to package and stack the yarn spindles separately. However, the current stacking method usually involves placing the yarn spindles directly on a pallet using grippers, and then stacking them layer by layer with the pallet. This method is prone to safety hazards such as unstable stacking of yarn spindles. To further improve the stability of yarn spindles during the stacking process, a yarn spindle packaging and stacking device with a machine vision positioning structure is now provided, which can eliminate the drawbacks of the existing device.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, such as Figures 1-4As shown, a yarn spindle packaging and stacking device with a machine vision positioning structure includes a base plate 1. A tray 12 is provided on the upper surface of the base plate 1. Multiple sets of limiting cones 11 are fixedly connected laterally at equal intervals to the top of the tray 12. The outer wall of the limiting cone 11 is frustoconical. The bottom end of the tray 12 at the limiting cone 11 has a mating groove that matches the outer wall of the top of the limiting cone 11. Two limiting plates 4 are symmetrically formed on the outer wall of the tray 12. A limiting bracket 6 is installed at the top of the base plate 1. A support plate 8 is fixedly connected to one end of the limiting bracket 6. A packaging device body 9 is fixedly connected to the end of the support plate 8 away from the limiting bracket 6. The packaging device body 9 is located at one end of the base plate 1. The support plate 8 and the packaging device body are... Cameras 7 are installed at the top of each of the packaging devices 9. The cameras 7 are electrically connected to the control terminal via wires. Inside the main body 9 of the packaging device, there is a movable column 10. A cross slide 3 is installed on one side of the movable column 10. A limit slide rod 5 is fixedly connected to the top of the cross slide 3. A limit bracket 6 is slidably sleeved on the outer wall of the limit slide rod 5. A linear guide rail is installed at the bottom of the movable column 10. The linear guide rail is fixedly connected to the main body 9 of the packaging device. A limit rod is fixedly connected to the inner wall of the main body 9 of the packaging device. The movable column 10 is slidably sleeved on the outer wall of the limit rod. The cross slide 3 is located below the limit rod. An electric gripper is installed on the cross slide 3. A positioning mechanism for clamping and positioning the pallet 12 is provided on the base plate 1.

[0036] Positioning mechanisms include:

[0037] Two movable slide plates 204 are symmetrically slidably connected inside the base plate 1. Two connecting slide plates 205 are symmetrically slidably connected inside the base plate 1. The two movable slide plates 204 are located between the two connecting slide plates 205. The two movable slide plates 204 are fixedly connected to the two connecting slide plates 205 respectively.

[0038] In this embodiment, it should be noted that the machine vision positioning structure uses camera 7 to capture images and transmit them to the control terminal. Image processing software is used to analyze features and determine the position and direction of the spindle and the limiting cone 11, thereby achieving precise placement of the spindle.

[0039] In use, the positioning mechanism can limit the outer walls of the two limiting plates 4 to fit together, so that the tray 12 can be easily clamped and centered. Then, the camera 7 takes pictures and identifies the packaged yarn spindle and the limiting cone 11 respectively, so that the position of the yarn spindle and the limiting cone 11 can be identified by machine vision. Then, through the cross slide 3, the moving column 10, the linear guide rail and the limiting rod, the electric gripper can clamp and move the yarn spindle, so that the yarn spindle fits onto a limiting cone 11, so that the yarn spindle can be easily placed.

[0040] When multiple sets of limiting cones 11 on a tray 12 are all fitted with yarn spindles, the above operation is repeated so that another tray 12 can be placed on the upper surface of a tray 12 to facilitate the stable stacking of yarn spindles, thereby further improving the stability of yarn spindles during the stacking process.

[0041] In one embodiment, such as Figures 2-3 As shown, the positioning mechanism also includes:

[0042] A rotating assembly mounted on base plate 1;

[0043] The rotating assembly includes:

[0044] A two-way lead screw 207 is rotatably connected inside the base plate 1, and the two-way lead screw 207 is located between two movable slide plates 204;

[0045] The bidirectional lead screw 207 is equipped with a moving component for providing moving power to the moving slide plate 204;

[0046] The base plate 1 is provided with a limiting component for clamping and limiting the tray 12;

[0047] A drive assembly for rotating the bidirectional lead screw 207 is provided on the base plate 1;

[0048] The mobile components include:

[0049] Two movable sliders 202 are symmetrically sleeved on the outer wall of the bidirectional lead screw 207. Both movable sliders 202 are threadedly connected to the bidirectional lead screw 207. The top of each movable slider 202 is fixedly connected to a transmission push plate 209. The transmission push plate 209 is located above the two movable slide plates 204. The movable sliders 202 and the transmission push plate 209 are slidably connected to the base plate 1.

[0050] A guide assembly is provided on the transmission push plate 209;

[0051] The guiding components include:

[0052] Two guide sliders 203 are symmetrically fixedly connected to the bottom end of the transmission push plate 209. The movable slider 202 is located between the two guide sliders 203. Two movable slide plates 204 are respectively sleeved on the outer wall of the two guide sliders 203. A guide groove 206 is provided at the contact position between the movable slide plate 204 and the guide slider 203 for the guide slider 203 to slide. Through the mutual cooperation of the rotating component, the movable component and the guide component, the two movable slide plates 204 can be synchronously displaced in opposite directions.

[0053] In one embodiment, such as Figures 1-3 As shown, the limiting component includes:

[0054] Two positioning plates 201 are symmetrically arranged on the outside of the base plate 1. The two positioning plates 201 are fixedly connected to the two connecting slide plates 205 respectively. Both positioning plates 201 are slidably connected to the base plate 1. The two positioning plates 201 are respectively sleeved on the outer walls of the two limiting plates 4. The positioning plates 201 and the limiting plates 4 are provided with limiting grooves that match the outer walls of the limiting plates 4. By limiting the sleeve connection of the two positioning plates 201 to the outer walls of the two limiting plates 4, the tray 12 can be conveniently clamped and centered, effectively preventing the spindles from being misaligned when multiple trays 12 are stacked, which would make it difficult to stack the spindles stably.

[0055] In one embodiment, such as Figures 1-3 As shown, the driving component is a motor 208 installed on the outer wall of the bottom plate 1 away from the main body 9 of the packaging device. The output end of the motor 208 is fixedly connected to the bidirectional lead screw 207, and the motor 208 can provide rotational power to the bidirectional lead screw 207.

[0056] The above embodiments disclose a yarn spindle packaging and stacking device with a machine vision positioning structure. In use, the start motor 208 drives the bidirectional lead screw 207 to rotate. At this time, the two movable sliders 202, driven by the thread of the bidirectional lead screw 207, drive the transmission push plate 209 to move closer to each other along the inner wall of the base plate 1. At the same time, the two guide sliders 203 are synchronously displaced under the drive of the transmission push plate 209. At this time, the two movable slide plates 204 move away from each other under the squeezing guidance of the guide sliders 203 through the guide groove 206. Meanwhile, the two positioning pressure plates 201 are separated from the base plate 1 by the connecting slide plate 205 under the push of the two movable slide plates 204. Then, the limiting cone 11 is placed on the upper surface of the base plate 1 and located between the two positioning pressure plates 201, so that the tray 12 can be conveniently placed.

[0057] Then, the motor 208 is started to drive the bidirectional lead screw 207 to rotate in the opposite direction, thereby reversing the above operation. This allows the two positioning plates 201 to be sleeved on the outer walls of the two limiting plates 4 through the limiting sleeve grooves, until both positioning plates 201 are in contact with the outer wall of the support plate 12, thereby making it easy to clamp and center the support plate 12.

[0058] Then, the packaged yarn spindle and the limiting cone 11 are photographed and identified by the camera 7. The positions of the yarn spindle and the limiting cone 11 can be identified by machine vision. Then, the electric gripper can clamp the yarn spindle and move it above a limiting cone 11 by the cross slide 3, the moving column 10, the linear guide rail and the limiting rod. At this time, the electric gripper is released so that the yarn spindle can be fitted onto a limiting cone 11. This allows the yarn spindle to be placed conveniently. During this process, the sliding connection between the limiting slide rod 5 and the limiting bracket 6 effectively prevents the cross slide 3 from tilting forward.

[0059] When multiple sets of limiting cones 11 on a tray 12 are all fitted with yarn spindles, the above operation is repeated. Another tray 12 can be placed on the upper surface of the first tray 12. At the same time, the other tray 12 fits the outer wall of the multiple sets of limiting cones 11 through the mating groove, so as to achieve stable stacking of yarn spindles and further improve the stability of yarn spindles during the stacking process.

[0060] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
