Description

Technical Field

[0001] This application relates to the field of handling device technology, specifically to a bidirectional handling device. Background Technology

[0002] Bidirectional material handling devices enable forward and reverse flow of materials on the production line, improving work efficiency. Furthermore, they can adapt to changes in production line requirements, optimize processes, and reduce downtime. With the integration of intelligent and information technologies, bidirectional material handling devices are more precise and faster, enhancing operational safety.

[0003] In related technologies, bidirectional conveying devices typically employ a combination of cams and guide slots to achieve lifting and lowering, enabling synchronous bidirectional material transport. While this design improves stability and reliability, such mechanical systems generate significant noise during long-term operation, and the continuous friction between components causes severe mechanical wear. This wear not only affects conveying accuracy but also increases subsequent maintenance costs. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] Bidirectional material handling devices enable forward and reverse flow of materials on the production line, improving work efficiency. Furthermore, they can adapt to changes in production line requirements, optimize processes, and reduce downtime. With the integration of intelligent and information technologies, bidirectional material handling devices are more precise and faster, enhancing operational safety.

[0050] In related technologies, bidirectional conveying devices typically employ a combination of cams and guide grooves to achieve lifting and lowering, enabling synchronous bidirectional material transport. While this design improves stability and reliability, such mechanical systems generate significant noise during long-term operation, and the continuous friction between components causes severe mechanical wear. This wear not only affects conveying accuracy but also increases subsequent maintenance costs. Therefore, this application provides a bidirectional conveying device that solves or improves the problems of severe wear and decreased conveying accuracy with prolonged operation.

[0051] The following is combined with Figures 1 to 5 This describes an embodiment of the present application.

[0052] According to an embodiment of this application, a bidirectional transport device is provided, including: a first frame 1, a first transport mechanism 2, a second transport mechanism 3, and a controller.

[0056] The first side of the first frame 1 is arranged opposite to the second side of the first frame 1.

[0057] In this embodiment, such as Figure 1 As shown, one end of the first frame 1 along the first direction X is the material picking end, and the other end is the material feeding end. The initial positions of the first conveying mechanism 2 and the second conveying mechanism 3 are respectively set at the material picking end and the material feeding end. The robotic arm places the material on the first conveying platform 202 of the first conveying mechanism 2. The first conveying mechanism 2 moves towards the material feeding end along the first direction X. At the same time, the second conveying mechanism 3 moves towards the material picking end along the first direction X. The first lifting component 201 raises the first conveying platform 202, and the second lifting component 301 lowers the second conveying platform 302, so that the first conveying platform 202 and the second conveying platform 302 are misaligned to avoid affecting the movement of the first conveying mechanism 2 and the second conveying mechanism 3 along the first direction X.

[0058] The first transport mechanism 2 and the second transport mechanism 3 are slidably connected to the first frame 1, and the first transport platform 202 and the second transport platform 302 are raised and lowered by the first lifting assembly 201 and the second lifting assembly 301 without wear.

[0059] The first handling mechanism 2 and the second handling mechanism 3 move back and forth along the first direction X on the first frame 1 to continuously transport materials from the picking end to the feeding end, thereby improving work efficiency.

[0063] In this embodiment, the first slide plate is connected to the first slide groove, resulting in greater stability.

[0064] In one embodiment, the first conveying mechanism 2 further includes a first slide rail 205 and a first sliding frame 206. Specifically, the first slide rail 205 is mounted on the first connecting frame 204 along the lifting direction of the first lifting assembly 201; the first sliding frame 206 is slidably connected to the first slide rail 205, the lifting end of the first lifting assembly 201 is connected to the first sliding frame 206, and the first conveying platform 202 is mounted on the first sliding frame 206.

[0065] In this embodiment, such as Figure 1 and Figure 2 As shown, the first slide rail 205 is fixed on the first connecting frame 204, and the first sliding frame 206 is slidably connected to the first slide rail 205, making the sliding of the first sliding frame 206 smoother.

[0066] Specifically, such as Figure 1 and Figure 2 As shown, two first slide rails 205 are provided, and the two first slide rails 205 are fixed on both sides of the first connecting frame 204. The first sliding frame 206 is set as an inverted U-shaped frame, and the two sides of the inverted U-shaped frame are slidably connected to the two first slide rails 205 respectively. The first transport platform 202 is installed on the top of the inverted U-shaped frame.

[0067] Specifically, it also includes multiple third sliders, which are slidably connected to two first slide rails 205, and the two sides of the first sliding frame 206 are respectively connected to the multiple third sliders.

[0068] In one embodiment, such as Figure 1 and Figure 2 As shown, the first conveying mechanism 2 also includes a first driving mechanism 207, which is mounted on the first frame 1. The driving end of the first driving mechanism 207 is connected to the first slider 203 via a first transmission assembly. The first driving mechanism 207 is electrically connected to the controller.

[0070] The first transmission assembly includes a first lead screw and a first nut. Specifically, the first lead screw extends along a first direction X. One end of the first lead screw is connected to the output shaft of the first drive motor via a coupling, and the other end is rotatably connected to the first frame 1. The outer wall of the first nut is fixed on the first slider 203 and threadedly connected to the first lead screw.

[0071] In this embodiment, the first drive motor drives the first lead screw to rotate, the first nut is threadedly connected to the first lead screw, the first nut moves along the first lead screw and drives the first slider 203 to move, thereby driving the first transport platform 202 to move along the first direction X.

[0072] Specifically, the first drive motor is a servo motor, which improves the movement accuracy of the first handling platform 202.

[0073] In one embodiment, such as Figure 1 As shown, it also includes a vision inspection mechanism 5. The detection end of the vision inspection mechanism 5 can correspond to the first transport platform 202 or the second transport platform 302. The vision inspection mechanism 5 is electrically connected to the controller.

[0074] In this embodiment, such as Figure 1 As shown, the first drive mechanism 207 drives the first transport platform 202 to move through the first transmission component. When the first transport platform 202 moves along the first direction X, it passes the vision inspection mechanism 5. The first drive mechanism 207 stops working and the vision inspection mechanism 5 inspects the material on the first transport platform 202. If the inspection is qualified, the first drive mechanism 207 is started to transport the material to the feeding end.

[0075] In one embodiment, such as Figure 1 As shown, the visual inspection mechanism 5 includes a second support 501 and a detection probe 503. Specifically, the second support 501 is provided with a detection hole 502, and the first transport platform 202 or the second transport platform 302 can correspond to the detection hole 502. The detection probe 503 is installed on the second support 501, and the detection probe 503 is arranged corresponding to the detection hole 502. The detection probe 503 is electrically connected to the controller.

[0076] In this embodiment, such as Figure 1 As shown, the first drive mechanism 207 drives the first transport platform 202 to move to the position corresponding to the detection hole 502. The detection probe 503 detects the material on the first transport platform 202 through the detection hole 502. If the detection is qualified, the controller controls the first drive mechanism 207 to start and transport the material to the feeding end.

[0077] Specifically, such as Figure 1 As shown, the second support 501 is an inverted U-shaped frame. A detection hole 502 is opened on the top of the second support 501. The two side plates of the second support 501 are arranged corresponding to the first side and the second side of the first support. The top of the second support 501 is located above the first support. The detection hole 502 can be arranged corresponding to the first transport platform 202 and the second transport platform 302.

[0078] In one embodiment, such as Figure 1 As shown, the visual inspection mechanism 5 also includes: a detection light source 504, which is installed on the inner wall of the detection hole 502 and is electrically connected to the controller.

[0079] In this embodiment, such as Figure 1 As shown, the detection light source 504 is installed on the inner wall of the detection hole 502. When the first transport platform 202 or the second transport platform 302 corresponds to the detection hole 502, it can provide supplementary lighting for the materials on the first transport platform 202 and the second transport platform 302, thereby improving the accuracy of the detection probe 503. The detection light source 504 is installed on the inner wall of the detection hole 502 and does not affect the detection probe 503 from detecting the materials on the first transport platform 202 and the second transport platform 302.

[0080] In one embodiment, such as Figure 3and Figure 4 As shown, it also includes: multiple first positioning sensors 6 and first sensing plates 7. Specifically, multiple first positioning sensors 6 are installed at intervals along the first direction X on the first frame 1, and the first positioning sensors 6 are electrically connected to the controller; the first sensing plates 7 are installed on the first slider 203, and the first sensing plates 7 can be arranged corresponding to the multiple first positioning sensors 6 respectively.

[0081] In this embodiment, multiple first positioning sensors 6 are installed at preset positions on the first frame 1. When the first driving mechanism 207 drives the first slider 203 to move, when the first sensing plate 7 corresponds to one of the first positioning sensors 6, the first positioning sensor 6 transmits a signal to the controller, and the controller selects to control the first driving mechanism 207 to stop or start.

[0082] Specifically, it includes three first positioning sensors 6, which are located on the first side of the first frame 1 and are respectively set at the material picking end, the material feeding end and the position corresponding to the detection hole 502 of the first frame 1.

[0083] In one embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, the second conveying mechanism 3 includes:

[0084] The second slider 303 is slidably connected to the second side of the first frame 1;

[0085] The second connecting frame 304 is connected to the second slider 303, and the second lifting assembly 301 is installed on the second connecting frame 304;

[0086] The second slide rail 305 is installed on the second connecting frame 304 along the lifting direction of the second lifting assembly 301;

[0089] Specifically, the second slide plate is connected to the second slide rail, which provides greater stability.

[0090] Specifically, two second slide rails 305 are provided, and the two second slide rails 305 are fixed on both sides of the second connecting frame 304. The second sliding frame 306 is set as an inverted U-shaped frame, and the two sides of the inverted U-shaped frame are slidably connected to the two second slide rails 305 respectively. The second transport platform 302 is installed on the top of the inverted U-shaped frame.

[0091] Specifically, it also includes multiple fourth sliders 4, which are slidably connected to two second slide rails 305, and the two sides of the second sliding frame 306 are respectively connected to multiple second sliders 303.

[0092] Specifically, the second drive mechanism 307 is the second drive motor.

[0093] Specifically, the second transmission assembly includes: a second lead screw and a second nut. The second lead screw extends along the first direction X. One end of the second lead screw is connected to the output shaft of the second drive motor via a coupling, and the other end is rotatably connected to the first frame 1. The outer wall of the second nut is fixed on the second slider 303 and threadedly connected to the second lead screw.

[0094] Specifically, the first drive motor drives the second lead screw to rotate, the second nut is threadedly connected to the second lead screw, the second nut moves along the second lead screw and drives the second slider 303 to move, thereby driving the second transport platform 302 to move along the first direction X.

[0095] Specifically, the second drive motor is a servo motor, which improves the movement accuracy of the second handling platform 302.

[0096] Specifically, such as Figure 3 As shown, it also includes multiple second positioning sensors 8 and second sensing plates. The multiple second positioning sensors 8 are installed at intervals along the first direction X on the first frame 1, and the second positioning sensors 8 are electrically connected to the controller. The second sensing plates are installed on the second slider 303, and the second sensing plates can be arranged corresponding to the multiple second positioning sensors 8 respectively.

[0097] Specifically, multiple second positioning sensors 8 are installed at preset positions on the first frame 1. When the second drive mechanism 307 drives the second slider 303 to move, when the second sensing plate corresponds to one of the second positioning sensors 8, the second positioning sensor 8 transmits a signal to the controller, and the controller selects to control the second drive mechanism 307 to stop or start.

[0098] Specifically, there are three second positioning sensors 8, which are located on the second side of the first frame 1 and are respectively set at the material picking end, the material feeding end and the position corresponding to the detection hole 502 of the first frame 1.

[0099] Specifically, the first positioning sensor 6 and the second positioning sensor 8 are model EE-SX672.

[0100] The following is an example, combined with Figures 1 to 5 A comprehensive explanation of all the above-mentioned plans is provided.

[0101] In the initial position, the first slider 203 is located at the picking end, the first sensing plate 7 is arranged correspondingly to the first positioning sensor 6 at the picking end, the controller controls the first drive motor to stop working, and the first conveying platform 202 is located at the picking end; the second slider 303 is located at the feeding end, the second sensing plate is arranged correspondingly to the second positioning sensor 8 at the feeding end, the controller controls the second drive motor to stop working, and the second conveying platform 302 is located at the feeding end.

[0102] After starting work, the robotic arm places the material at the picking end. The first drive mechanism 207 and the second drive mechanism 307 work simultaneously, driving the first slider 203 and the second slider 303 to move towards each other via the first conveying component and the second transmission component, respectively. The first lifting component 201 lifts the first transport platform 202 upward, bringing it close to the detection hole 502. The detection probe 503 detects the material. When the first positioning sensor 6 and the first sensing plate 7 ensure that the first transport platform 202 is directly below the detection hole 502, the first drive mechanism 207 stops working and resumes work after the detection is completed. At the same time, the second lifting component 301 conveys the second transport platform 302 downward, causing the second transport platform 302 to be staggered with the first transport platform 202. After the material on the first transport platform 202 passes the detection, the first drive mechanism 207 continues working, conveying the first transport platform 202 to the feeding end. At this time, the second transport platform 302 is located at the picking end.

[0103] The first transport platform and the second transport platform 302 move cyclically along the first direction X, simultaneously feeding and picking up materials, thereby improving work efficiency.

[0104] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
