Description

Technical Field

[0001] This application belongs to the field of lifting equipment technology, and specifically relates to a positioning mechanism and a lifting device. Background Technology

[0002] When a workpiece needs to be processed across production lines, it needs to be raised by a lifting device so that the processing equipment can process the raised workpiece. Then the processed workpiece is lowered and output with the production line.

[0003] In related technologies, a single lifting device can only position and lift one type of material, resulting in poor versatility. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a lifting device that can position different materials to lift different materials.

[0005] An embodiment of this application provides a positioning mechanism, including a base, a cam, and multiple lifting components. The base has a platform for carrying different materials. Each lifting component includes a support plate, a protrusion, and a connector. The protrusion and connector are respectively disposed on opposite sides of the support plate. The support plate is disposed on the base and can be raised and lowered relative to the base, allowing the connector connected to the support plate to pass through the platform to position the corresponding material. The cam can move relative to the base in a first direction. When the cam moves to the end of the protrusion away from the support plate, it can lift the protrusion to the end of the cam close to the platform, causing the corresponding support plate to drive the connector to pass through the platform.

[0006] In the aforementioned positioning mechanism, a connector corresponding to the material being carried on the platform is pre-selected. This pre-selected connector and its corresponding protrusion are connected to the same support plate. The cam moves to the end of the protrusion corresponding to the pre-selected connector that is furthest from the support plate, lifting the protrusion to the end of the cam closest to the platform. This causes the support plate to move the pre-selected connector through the platform, positioning the material on the platform. Therefore, the positioning mechanism can position different materials and has good versatility.

[0007] In some embodiments, the positioning mechanism further includes a lead screw assembly, which includes a lead screw and a lead nut, with a cam connected to the lead nut. Rotation of the lead screw causes the lead nut to move relative to the base in a first direction, thereby driving the cam to move relative to the base.

[0008] In some embodiments, the base is provided with a guide member, which includes a slide rail extending in a direction parallel to a first direction, and a cam connected to the slide rail to guide the cam to move in the first direction.

[0009] In some embodiments, a slider is slidably connected to a slide rail, and the slider is connected to a nut to guide the nut to move along a first direction. A cam is a roller connected to the slider and capable of rolling relative to the slider around a second direction, which is a horizontal direction perpendicular to the first direction.

[0010] In some embodiments, the bump has a track corresponding to a cam, and the cam is movable along the track in a first direction.

[0011] In some embodiments, each support plate is connected to two protrusions, which are spaced apart along a first direction on the support plate. There are two cams, each corresponding to one protrusion.

[0012] In some embodiments, the lead screw includes a left-hand thread and a right-hand thread, which are centrally symmetrical about the lead screw in a first direction. Two protrusions connected to a support plate are centrally symmetrical about the lead screw in the first direction, so that rotation of the lead screw can drive two cams to move simultaneously toward or away from each other.

[0013] In some embodiments, the connector includes four connecting rods, all of which pass through the platform. Two connecting rods are spaced apart along a first direction, and the other two connecting rods are spaced apart along a horizontal direction perpendicular to the first direction.

[0014] In some embodiments, the base includes a base plate, a frame, and a reference frame. The frame and the reference frame are both connected to the base plate, the platform is fixedly connected to the frame, and the reference frame is used to support multiple support plates.

[0015] An embodiment of this application also provides a lifting device, including multiple cylinders and a positioning mechanism from the previous embodiment. The multiple cylinders are connected to the bottom of the positioning mechanism to drive the positioning mechanism and the material to rise and fall.

[0016] The aforementioned lifting equipment can lift materials positioned by a positioning mechanism driven by a cylinder. The positioning mechanism can position different materials, therefore, the lifting equipment can be used to lift different materials and has good versatility. Attached Figure Description

[0024] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] In this application, unless otherwise expressly specified and limited, the terms "connected", "linked", "fixed", etc., should be interpreted broadly. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0028] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0029] In the description of the embodiments of this application, the term "perpendicular" is used to describe the ideal state between two components. In actual production or use, two components may exist in a state that is approximately perpendicular. The two components described as "perpendicular" may not be absolutely straight lines or planes, but may be approximately straight lines or planes. From a macroscopic perspective, if the overall extension direction is a straight line or plane, the component can be considered as a "straight line" or "plane".

[0030] The term "parallel" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately parallel. The two components described as "parallel" do not have to be absolute straight lines or planes, but can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.

[0032] When a workpiece needs to be processed across production lines, a positioning mechanism is required to raise the workpiece so that the processing equipment can process it. The processed workpiece is then lowered and output along the production line. However, in related technologies, a single lifting device can only position and lift one type of material, resulting in poor versatility.

[0033] This application provides a positioning mechanism capable of positioning and lifting different materials. The positioning mechanism includes a base, a cam, and multiple lifting components. The base has a platform for supporting different materials. Each lifting component includes a support plate, a protrusion, and a connector. The protrusion and connector are respectively located on opposite sides of the support plate. The support plate is located on the base and can rise and fall relative to the base, allowing the connector connected to the support plate to pass through the platform to position the corresponding material. The cam can move relative to the base in a first direction. When the cam moves to the end of the protrusion away from the support plate, it can lift the protrusion to the end of the cam close to the platform, causing the corresponding support plate to drive the connector through the platform.

[0034] In the above positioning mechanism, according to the type of material carried on the platform, a connector corresponding to the material is pre-selected. The pre-selected connector and the corresponding protrusion are connected to the same support plate, so that the cam moves to the end of the protrusion corresponding to the pre-selected connector away from the support plate, so as to lift the protrusion to the end of the cam close to the platform, thereby causing the support plate to drive the pre-selected connector through the platform, so that the connector positions the material on the platform.

[0035] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0036] Please see Figure 1 An embodiment of this application provides a lifting device (not shown) for lifting materials. The lifting device includes a positioning mechanism 100, which is used to position different materials.

[0037] In some embodiments, the material includes a workpiece (not shown) and a carrier 310. The carrier 310 has multiple receiving slots 3101 for accommodating the workpieces, and can accommodate multiple workpieces simultaneously, so that multiple workpieces can be lifted and lowered at the same time, which helps to improve efficiency. One type of carrier 310 is used to accommodate the same type of workpiece. Different carriers 310 can be provided depending on the type of workpiece.

[0038] Please see Figure 2 In some embodiments, the positioning mechanism 100 includes a base 10 (see figure 10). Figure 1 The base 10 includes a cam 30 and multiple lifting components 20. The base 10 has a platform 14. The platform 14 can support different carriers 310. The cam 30 can move relative to the base 10 to lift a pre-selected lifting component 20.

[0039] Each lifting assembly 20 includes a support plate 21, a protrusion 22, and a connector 23. The protrusion 22 and the connector 23 are respectively located on opposite sides of the support plate 21. The support plate 21 is located on the base 10 and can be raised and lowered relative to the base 10. When the support plate 21 rises, it can drive the connected connector 23 to pass through the platform 14 to position the corresponding material.

[0040] When the cam 30 moves relative to the base 10 to the end of the preselected protrusion 22 away from the support plate 21, the cam 30 can lift the protrusion 22 to the end of the cam 30 close to the platform 14, so as to lift the support plate 21 connected to the preselected cam 30, thereby enabling the lifted support plate 21 to drive the connected connector 23 through the platform 14.

[0041] In some embodiments, the bottom of the carrier 310 is provided with a positioning hole (not shown). The positioning hole can accommodate the connector 23. When the connector 23 passes through the platform 14, the connector 23 is inserted into the positioning hole to position the carrier 310, thereby achieving the effect of positioning the material.

[0042] In use, depending on the type of material carried on the platform 14, a connector 23 that can be inserted into the carrier 310 is pre-selected. The pre-selected connector 23 and the corresponding protrusion 22 are connected to the same support plate 21. The cam 30 is driven to move to the bottom end of the protrusion 22 corresponding to the pre-selected connector 23, so that the cam 30 lifts the protrusion 22 to the top of the cam 30. This causes the corresponding support plate 21 to drive the pre-selected connector 23 through the platform 14 and insert it into the carrier 310 to position the material.

[0043] Therefore, different lifting components 20 can be selected for positioning different materials. Such a positioning mechanism 100 can position different carriers 310, and has good versatility.

[0044] In some embodiments, the lifting assembly 20 may be two, three, or more, depending on the application. When multiple support plates 21 contact the base 10, the bottom ends of multiple protrusions 22 have the same preset height relative to the base 10, and multiple connectors 23 have the same preset height relative to the platform 14. The cam 30 can lift different connectors 23 by abutting against different protrusions 22 to position different materials.

[0045] In some embodiments, the connector 23 is a plurality of connecting rods 231. The number of connecting rods 231 may be two, three or more, and the number of connecting rods 231 is not limited here. The connecting rods 231 need to be able to be inserted into the vehicle 310 to restrict the horizontal movement of the vehicle 310.

[0046] In some embodiments, the connecting rod 231 is a polygonal columnar structure, extending along the lifting direction of the support plate 21. The lifting direction of the support plate 21 is perpendicular to the horizontal direction, that is, the lifting direction of the support plate 21 is the vertical direction Z.

[0047] In some embodiments, the connecting rod 231 is cylindrical.

[0048] In some embodiments, the connector 23 includes four connecting rods 231. All four connecting rods 231 pass through the platform 14. Two connecting rods 231 are spaced apart along a first direction X. The other two connecting rods 231 are spaced apart along a horizontal direction perpendicular to the first direction X to position the carrier 310 and prevent the carrier 310 from swaying left and right in the horizontal direction during lifting and lowering.

[0049] Please see Figure 2 In some embodiments, the positioning mechanism 100 further includes a lead screw assembly 40. The lead screw assembly 40 includes a lead screw 41 and a lead screw 42. A cam 30 is connected to the lead screw 42. Rotation of the lead screw 41 causes the lead screw 42 to move relative to the base 10 in a first direction X, thereby causing the cam 30 to move relative to the base 10.

[0050] In some embodiments, the lead screw assembly 40 further includes a motor 43, which is coaxially connected to the lead screw 41 to drive the lead screw 41 to rotate, thereby moving the cam 30 relative to the base 10.

[0051] In some embodiments, the base 10 includes a base plate 11. A guide 50 is provided on the base plate 11. The guide 50 includes a slide rail 51. The slide rail 51 extends parallel to a first direction X. A cam 30 is connected to the slide rail 51 to guide the cam 30 to move along the first direction X, thereby preventing the cam 30 from wobbling.

[0052] In some embodiments, there are two slide rails 51. The two slide rails 51 are located on opposite sides of the lead screw 41 along the second direction Y. The second direction Y and the first direction X are two mutually perpendicular horizontal directions. The two slide rails 51 make the cam 30 more stable when moving along the first direction X.

[0053] In some embodiments, the slide rail 51 is slidably connected to a slider 52. The slider 52 is connected to the nut 42 to guide the nut 42 to move along the first direction X and prevent the nut 42 from rotating while moving along the first direction X.

[0054] In some embodiments, the cam 30 is a roller. The roller is connected to the slider 52 to guide its movement along a first direction X. The roller can roll relative to the slider 52 about a second direction Y, i.e., the axis of rotation of the roller is parallel to the second direction Y. When the lead screw assembly 40 drives the roller to move along the first direction X, the roller rolls relative to the protrusion 22 so that the roller rolls to the bottom end of the protrusion 22, preventing the cam 30 from colliding with the protrusion 22.

[0055] Please see Figure 3 In some embodiments, the protrusion 22 has a track 221. The track 221 corresponds to the cam 30. The cam 30 can move along the track 221 relative to the base 10 in a first direction X. Guiding the movement of the cam 30 by the track 221 ensures that the cam 30 is precisely aligned with the protrusion 22 and prevents the cam 30 from disengaging from the track 221 during movement.

[0056] Please see Figure 2 In some embodiments, each support plate 21 is connected to two protrusions 22. The two protrusions 22 are spaced apart along a first direction X on the same support plate 21. There are two cams 30, each corresponding to one protrusion 22. The two cams 30 move simultaneously, so that one cam 30 is located at the bottom end of one protrusion 22, thereby lifting both ends of the support plate 21, improving the stability of the lifting assembly 20, and preventing the support plate 21 from tilting due to one end of the lifting assembly 20 being lifted.

[0057] In some embodiments, the protrusion 22 is connected to the center of the lifting plate along the second direction Y to improve the stability of the lifting assembly 20 during lifting.

[0058] Please see Figure 2In some embodiments, the lead screw 41 includes a left-hand thread 411 and a right-hand thread 412. The left-hand thread 411 and the right-hand thread 412 are centrally symmetrical about the lead screw 41 in a first direction X. Two protrusions 22 connected to a support plate 21 are centrally symmetrical about the lead screw 41 in the first direction X, so that rotation of the lead screw 41 can drive two cams 30 to move simultaneously toward or away from each other.

[0059] By simultaneously driving two cams 30 to move through a lead screw assembly 40, the two protrusions 22 can be simultaneously raised and lowered, thus enabling the lifting assembly 20 to rise and fall smoothly.

[0060] Please see Figures 1 to 5 In some embodiments, the base 10 further includes a frame 12 and a reference frame 13. Both the frame 12 and the reference frame 13 are connected to the base plate 11. The platform 14 is fixedly connected to the frame 12 by screws 121 (see figure). Figure 2 The lifting assembly 20, lead screw assembly 40, cam 30, and guide member 50 are partially shielded, thus protecting them to a certain extent. The reference frame 13 supports multiple support plates 21. The reference frame 13 provides support for the support plates 21, allowing the support plates 21 and protrusions 22 to be spaced apart from the base plate 11, facilitating the protrusions 22 to drive any one of the support plates 21 upwards.

[0061] Please see Figure 5 In some embodiments, when the support plate 21 is located on the reference frame 13, the support plate 21 is spaced apart from the platform 14. The connector 23 passes through the platform 14 but does not protrude from the top of the platform 14. When the support plate 21 is raised, the support plate 21 contacts the platform 14, and the connector 23 protrudes from the top of the platform 14.

[0062] In some embodiments, the lifting device further includes a plurality of cylinders. The plurality of cylinders are connected to the bottom of the positioning mechanism 100 to drive the positioning mechanism 100 and the material lifting.

[0063] In some embodiments, four guide columns 111 are connected to the lower part of the base plate 11. The lifting device also includes four cylinders, which are respectively connected to the four guide columns 111 to drive the positioning mechanism 100 and the material carried by the positioning mechanism 100 to lift.

[0064] In some embodiments, the lifting device is provided with conveyor belts on both sides for conveying the carrier 310 along the first direction X. When the carrier 310 is positioned by the positioning mechanism 100, the carrier 310 does not move with the conveyor belt. When the positioning mechanism 100 cancels the positioning of the carrier 310, the carrier 310 moves with the conveyor belt.

[0065] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of disclosure of this application.
