[0001] The present application relates to the field of automated production technology, and in particular to a lifting mechanism and an assembly line. Background Art

[0002] To improve production efficiency, assembly lines use a combination of diversion, merging, and lifting to achieve automated conveying of workpieces. For example, during the conveying process, a lifting mechanism is often required to lift the workpiece to connect it to the secondary mechanism.

[0003] Since the jacking mechanism needs to occupy a large height space, if the jacking mechanism is directly installed on the conveyor line, and the conveyor line needs to be used for the flow of workpieces, the installation position of the conveyor line is limited, which will lead to the installation of the jacking mechanism being restricted and affect the jacking operation of the jacking mechanism.

[0035] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0036] See Figure 1 As shown, the present application provides a lifting mechanism 100, which includes a lifting assembly 110 and a clamping assembly 120. The lifting mechanism 100 is used to lift a workpiece (not shown) and remove it from a conveyor line (not shown) so that the workpiece can dock with a secondary mechanism (such as a code scanning mechanism, a material unloading mechanism, etc.) to complete the corresponding operation. The conveyor line can be a chain conveyor line, a belt conveyor line, etc.

[0037] The lifting assembly 110 is disposed below the conveyor line and is used to lift the workpiece. Since the conveyor line is used for the circulation of workpieces, the installation space above the conveyor line is limited. By disposing the lifting assembly 110 below the conveyor line, the lifting assembly 110 does not occupy the conveying and circulation area of ​​the conveyor line, and the installation space of the lifting mechanism 100 is larger, which facilitates the installation of the lifting mechanism 100.

[0038] The clamping assembly 120 is connected to the lifting assembly 110 by transmission. When the workpiece flows on the conveyor line to the lifting station, the clamping assembly 120 can clamp the workpiece, and the lifting assembly 110 drives the clamping assembly 120 to move in the direction close to the conveying surface of the conveyor line to lift the workpiece and separate it from the conveyor line. On the contrary, after the lifting operation of the workpiece is completed, the lifting assembly 110 drives the clamping assembly 120 to move in the direction away from the conveying surface of the conveyor line, and the clamping assembly 120 is reset to avoid the lifting mechanism 100 from interfering with the flow of subsequent workpieces. The clamping assembly 120 is located on the outside of the lifting assembly 110. The clamping assembly 120 does not occupy the conveyor line space in the height direction (the direction of movement of the clamping assembly 120 during the lifting process), and the overall volume of the lifting mechanism 100 can be reduced in the height direction to achieve the installation and fixation of the lifting mechanism 100 in a smaller space.

[0039] In one embodiment, see Figure 1 As shown, the jacking assembly 110 includes a mounting frame 111, a first driving source 112, and a movable plate 113. The mounting frame 111 is arranged below the conveyor line body to fix the jacking assembly 110 below the conveyor line body. The jacking assembly 110 does not occupy the conveying flow area of ​​the conveyor line body, which facilitates the installation of the jacking mechanism 100. The first driving source 112 is arranged on the mounting frame 111, and the movable plate 113 is connected to the output end of the first driving source 112. The movable plate 113 is located on the side of the driving source away from the mounting frame 111, and the clamping assembly 120 is movably arranged on the movable plate 113. Specifically, when the workpiece needs to be lifted, the first driving source 112 outputs power to the movable plate 113. Since the clamping assembly 120 is arranged on the movable plate 113, the movable plate 113 can drive the clamping assembly 120 to move in the direction close to the conveying surface of the conveyor line body to lift the workpiece and detach it from the conveyor line body; on the contrary, when the lifting operation of the workpiece is completed, the second driving source 121 outputs power to the movable plate 113 in the reverse direction, and the movable plate 113 can drive the clamping assembly 120 to move in the direction away from the conveying surface of the conveyor line body to realize the reset operation of the clamping assembly 120.

[0040] Among them, the first driving source 112 can be a linear motor, a hydraulic cylinder, an electric cylinder or other components that can output power. This application does not limit the specific component type of the first driving source 112.

[0041] In one embodiment, see Figure 1 As shown, there are two clamping assemblies 120, and the two clamping assemblies 120 can move toward or away from each other. Figure 2 As shown, when the workpiece transferred to the lifting station needs to be clamped, the two clamping assemblies 120 face Figure 2 As shown in FIG. 1 , the two clamping assemblies 120 move toward each other, and the two clamping assemblies 120 can clamp the workpiece; on the contrary, refer to FIG. Figure 3 As shown, when the clamped workpiece needs to be released, the two clamping assemblies 120 are moved toward Figure 3 As shown in the B direction movement, the two clamping assemblies 120 move away from each other, and the two clamping assemblies 120 can release the workpiece. Among them, when the workpiece needs to be placed in a carrier for circulation, the clamping assembly 120 can indirectly complete the clamping operation of the workpiece by clamping the carrier. The two clamping assemblies 120 are symmetrically arranged on the opposite sides of the jacking assembly 110, and are both located on the outside of the jacking assembly 110. The clamping assembly 120 does not occupy the conveyor line space in the height direction, and the overall volume of the jacking mechanism 100 can be reduced in the height direction to achieve the installation and fixation of the jacking mechanism 100 in a smaller space. In addition, the collaborative clamping of the workpiece by the two clamping assemblies 120 can improve the stability of the workpiece during the clamping and jacking process.

[0042] In one embodiment, see Figure 1 As shown, the clamping assembly 120 includes a second driving source 121 and a clamping plate 122. The clamping plate 122 is movably disposed on the movable plate 113, and the clamping plate 122 is transmission-connected to the second driving source 121; or, the second driving source 121 is disposed on the movable plate 113, and the clamping plate 122 is connected to the output end of the second driving source 121. For example, in one embodiment, the clamping plate 122 is movably disposed on the movable plate 113, and the clamping plate 122 is transmission-connected to the second driving source 121, and the second driving source 121 outputs power to the clamping plate 122, which can drive the two clamping plates 122 relative to the movable plate 113 along the direction of rotation. Figure 2 Move in direction A to clamp the workpiece, or Figure 3 In another embodiment, the second driving source 121 is provided on the movable plate 113, and the clamping plate 122 is connected to the output end of the second driving source 121. The clamping plate 122 is indirectly movable on the movable plate 113 through the second driving source 121. When the second driving source 121 outputs power to the clamping plate 122, the two clamping plates 122 can be driven relative to the movable plate 113 along the direction of the clamping plate 122. Figure 2 The movement in the direction A shown in FIG. 1 is to clamp the workpiece, or to drive the two clamping plates 122 along the Figure 3 Movement in direction B shown is to release the workpiece.

[0043] Among them, the second driving source 121 can be a linear motor, a hydraulic cylinder, an electric cylinder or other components that can output power. This application does not limit the specific component type of the second driving source 121.

[0044] Specifically, see Figure 1 As shown, the clamping plate 122 includes a main body 1221 and a plurality of clamping blocks 1222. The main body 1221 is connected to the lifting assembly 110 by transmission. The clamping assembly 122 is connected to the lifting assembly 110 by transmission through the main body 1221. The plurality of clamping blocks 1222 are arranged at intervals on the main body 1221. The clamping blocks 1222 are used to support the workpiece. The plurality of clamping blocks 1222 cooperate to clamp the edge of the workpiece. The plurality of clamping blocks 1222 are arranged at intervals, which can improve the clamping stability of the plurality of clamping blocks 1222 on the workpiece. For example, see Figure 1 As shown, the clamping plate 122 includes two clamping blocks 1222, and the two clamping blocks 1222 are arranged along the Figure 2 The vertical direction is respectively arranged on the two opposite sides of the main body 1221; For example, the clamping plate 122 includes three clamping blocks 1222, and the three clamping blocks 1222 are arranged along Figure 2 Of course, for other numbers of clamping blocks 1222, they can be adaptively arranged according to the above examples, which will not be described in detail here.

[0045] Further, see Figure 1 As shown, the clamping block 1222 is L-shaped and is located on the side of the main body 1221 close to the lifting assembly 110. For example, the clamping block 1222 is located on the inner side of the two clamping assemblies 120. In this way, the edge of the workpiece can be placed on the clamping block 1222 in a lapped or resting manner to enable the clamping assembly 120 to support and clamp the workpiece. In addition, the L-shaped clamping block 1222 can position and support the position of the workpiece.

[0046] In one embodiment, see Figure 4 As shown, the lifting mechanism 100 further includes a clamping drive source 130. The clamping drive source 130 is in transmission connection with at least one of the two clamping assemblies 120, that is, the clamping drive source 130 can be in transmission connection with any one of the clamping assemblies 120, or can be in transmission connection with both of the clamping assemblies 120. By outputting power from the clamping drive source 130 to any one of the clamping assemblies 120, one of the clamping assemblies 120 can be driven toward the other clamping assembly 120 along the Figure 2 The movement in the direction A shown in FIG. 1 is to clamp the workpiece, or to drive one clamping assembly 120 toward another clamping assembly 120 along the Figure 3 Alternatively, the clamping drive source 130 outputs power to the two clamping assemblies 120, which can drive the clamping assemblies 120 to move synchronously along the direction B shown in FIG. Figure 2 The movement in the direction A shown in FIG. 1 is to clamp the workpiece, or to drive the two clamping assemblies 120 along the Figure 3 Movement in direction B shown is to release the workpiece.

[0047] Among them, the clamping drive source 130 can be a linear motor, a hydraulic motor, an electric cylinder or other components that can output power. This application does not limit the specific component type of the clamping drive source 130.

[0048] In one embodiment, see Figure 1 As shown, the lifting mechanism 100 further includes a sensing module 140, which is disposed on the lifting assembly 110 or the clamping assembly 120. The sensing module 140 is used to sense whether a workpiece is present in the clamping assembly 120. For example, the sensing module 140 is in communication with both the lifting assembly 110 and the clamping assembly 120. When the sensing module 140 senses the presence of a workpiece in the clamping assembly 120, the sensing module 140 feeds back a signal indicating the presence of a workpiece in the clamping assembly 120 to the lifting assembly 110. The lifting assembly 110 then outputs power and drives the clamping assembly 120 to move in a direction close to the conveying surface of the conveyor line, so that the clamping assembly 120 can perform a lifting operation on the workpiece. On the contrary, when the sensing module 140 senses that there is no workpiece in the clamping assembly 120, the sensing module 140 feeds back the signal that there is no workpiece in the clamping assembly 120 to the jacking assembly 110, and the jacking assembly 110 does not perform the jacking operation, or the jacking assembly 110 outputs power in reverse and drives the clamping assembly 120 to move in a direction away from the conveying surface of the conveyor line, and the clamping assembly 120 resets to avoid interference with the subsequent flow of workpieces caused by the jacking mechanism 100.

[0049] The sensing module 140 may be a position sensor, a proximity sensor, an infrared sensor, or other components capable of sensing the position of a workpiece. This application does not impose any restrictions on the specific component type of the sensing module 140 .

[0050] In one embodiment, see Figure 1 As shown, the jacking assembly 110 is detachably mounted on the conveyor line. For example, the jacking assembly 110 is detachably mounted on the conveyor line by means of magnetic attraction, screw connection, or the like, so that when the jacking position of the conveyor line changes, the jacking assembly 110 can be disassembled and re-fixed to the new jacking position, thereby improving the compatibility between the jacking mechanism 100 and the conveyor line; or, when the jacking mechanism 100 fails, the jacking assembly 110 can be disassembled and repaired or replaced, thereby reducing the cost of using the jacking mechanism 100.

[0051] In one embodiment, the lifting mechanism 100 further includes a guide member (not shown), which is disposed on the lifting assembly 110. When the lifting assembly 110 drives the clamping assembly 120 to move toward or away from the conveying surface of the conveyor line, the guide member is used to guide the clamping assembly 120, so that the clamping assembly 120 moves along a preset path to perform a lifting operation on the workpiece, thereby improving the accuracy of the clamping assembly 120's lifting position for the workpiece and the reliability of the lifting operation. For example, the guide member can be a guide shaft, a guide column, etc., and the extension direction of the guide member is consistent with the movement direction of the clamping assembly 120 during the lifting operation.

[0052] Also, see Figure 1 As shown, the present application also provides an assembly line (not shown). The assembly line includes a conveyor line body and a lifting mechanism 100 as described in the above technical solution. The conveyor line body is used to circulate workpieces, and the lifting mechanism 100 is disposed on the conveyor line body and located below the conveyor line body. The assembly line is used to circulate workpieces and lift and remove workpieces from the conveyor line body so that the workpieces can be docked with secondary mechanisms (such as a code scanning mechanism, a material unloading mechanism, etc.) to complete the corresponding operation.

[0053] In the above-mentioned production line, when the workpiece flows on the conveyor line body to the lifting station, the two clamping assemblies 120 move in a direction close to each other to clamp the workpiece, and the lifting assembly 110 drives the clamping assembly 120 to move in a direction close to the conveying surface of the conveyor line body to lift the workpiece and separate it from the conveyor line body. In the production line provided by the present application, the lifting assembly 110 is arranged below the conveyor line body, and the lifting assembly 110 does not occupy the conveying flow area of ​​the conveyor line body. The installation space of the lifting mechanism 100 is large, which is convenient for the installation of the lifting mechanism 100; and the clamping assembly 120 is symmetrically arranged on the outside of the lifting assembly 110. The clamping assembly 120 does not occupy the conveyor line body space in the height direction, which can reduce the overall volume of the lifting mechanism 100, so as to achieve the installation and fixation of the lifting mechanism 100 in a smaller space.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
