[0044] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0045] The embodiment of the present invention discloses a transfer device, which is used to transport a workpiece 100, specifically, to transfer the workpiece 100 by first moving it downward and then moving it horizontally. The workpiece 100 to be transferred can be a blank for subsequent machining, a processed part for subsequent assembly, or a tooling component (the tooling component is used to fix and hold the parts to be processed or assembled), or a component with other functions; the workpiece 100 to be transferred can be a columnar structure, a plate structure, a frame structure, or other external structures in terms of its external structure.

[0046] like Figures 1 to 9 As shown, the transfer device includes: a conveying platform 10, a stand 20, a vertical movement mechanism, a translation mechanism and a bearing component 70.

[0047] like Figure 1 As shown, the conveyor table 10 extends in the horizontal conveying direction required for the workpiece 100, and two horizontal guide rails 44 are arranged on the conveyor table 10, and the two horizontal guide rails 44 extend along the extension direction of the conveyor table 10; the stand 20 is vertically arranged on one side of the conveyor table 10, and close to the end of the conveyor table 10 (the end may be referred to as the starting end), and two vertical guide rails 34 are arranged on the stand 20. It is easy to understand that the two vertical guide rails 34 are in a vertical state with the two horizontal guide rails 44 on the conveyor table 10. Of course, the state in which the two types of guide rails are close to vertical can also be interpreted as a vertical state.

[0048] The vertical movement mechanism includes a first component 32 and a first driving mechanism. The first component 32 can slide on the vertical guide rail 34 via a slider 43 . The first driving mechanism is used to drive the first component 32 to move along the vertical guide rail 34 .

[0049] The translation mechanism includes a second component 42 and a second driving mechanism. The second component 42 can slide on the horizontal guide rail 44 via a slider 43 . The second driving mechanism is used to drive the second component 42 to move along the horizontal guide rail 44 .

[0050] The bearing component 70 is used to bear the workpiece 100 , that is, the bearing component 70 is used to place the workpiece 100 , and the bearing component 70 is transported by the vertical movement mechanism and the translation mechanism first and then to achieve the transfer of the workpiece 100 by first moving downward and then moving horizontally.

[0051] It should be noted that the initial position of the second component 42 is a position vertically corresponding to the first component 32 .

[0052] In this embodiment, the support member 70, the first member 32 and the second member 42 are configured in the following combination mode during the process of the workpiece 100 being transported:

[0053] The bearing member 70 is coupled to the first member 32 in a manner that it can move along the moving direction of the second member 42 and be separated from the first member 32 by the movement;

[0054] When the supporting member 70 approaches the second member 42 due to the downward movement of the first member 32 , the second member 42 is combined with the supporting member 70 in a manner that can drive the supporting member 70 to move.

[0055] Based on the above-mentioned combination method of the bearing component 70, the first component 32 and the second component 42, the transfer process of the transfer device of the present invention to the workpiece 100 is as follows:

[0056] like Figure 6 As shown, the bearing member 70 (at this time, the workpiece 100 is placed on the bearing member 70) combined with the first member 32 in the above manner moves from top to bottom under the drive of the first driving mechanism, as shown in FIG. Figure 7 and Figure 8 As shown, when the first component 32 makes the bearing component 70 close to the second component 42, the second component 42 is combined with the bearing component 70 in the above manner, and then the second driving mechanism drives the second component 42 to move horizontally in the extension direction of the conveying platform 10. At the same time, as shown in FIG. Fig. 9 As shown, the bearing member 70 moves with the second member 42 due to the above-mentioned combination, so that the bearing member 70 automatically separates from the first member 32 and follows the second member 42 to realize horizontal transportation of the workpiece 100 along the extension direction of the conveying platform 10 .

[0057] The transfer device of the present invention enables the support component 70 to be combined with the first component 32 in a manner that it can be separated from the first component 32 by movement, and enables the support component 70 to be combined with the second component 42 in a manner that it can be driven by the second component 42 when approaching the second component 42, thereby enabling the support component 70 on which the workpiece 100 is placed to automatically switch from vertical transportation to horizontal transportation, thereby realizing automatic transportation of the workpiece 100 to avoid manual or lifting transportation.

[0058] In an optional embodiment of the present invention, the carrying component 70 is moved along the moving direction of the second component 42 by means of a guide structure so as to be able to separate from the first component 32 .

[0059] It should be noted that the above-mentioned guiding structure should be understood as a structure that only allows the bearing component 70 to move in the moving direction of the second component 42 in the horizontal direction.

[0060] There may be various guide structures with the above features. For example, two guard plates may be provided on the first component 32 to limit the movement of the bearing component 70 in a direction perpendicular to the movement direction of the second component 42 and only allow movement in the movement direction of the second component 42 .

[0061] In an optional embodiment of the present invention, Figures 5 to 7 Combined with Figures 1 to 4 As shown, the guide structure includes a guide groove 51 and a guide bar 52. A bar block 511 is fixed on the side of the bearing component 70 opposite to the stand 20, and the bar block 511 extends in the moving direction of the second component 42. The guide groove 51 is opened at the bottom of the bar block 511, and extends along the moving direction of the second component 42 and penetrates the bar block 511. The guide bar 52 is formed on the first component 32, and the guide bar 52 extends into the guide groove 51. In this embodiment, on the one hand, the guide bar 52 extends into the guide groove 51 so that the bearing component 70 can move along the moving direction of the second component 42 so as to be able to be separated from the first component 32 by movement; on the other hand, the first component 32 can receive the bearing component 70, and limit the bearing component 70 from moving in a direction perpendicular to the moving direction of the second component 42, and at the same time keep the bearing component 70 in a horizontal state. Preferably, the guide structure includes two pairs of parallel arrangements to improve the bearing capacity of the first component 32 for the bearing component 70.

[0062] The cross-section of the guide groove 51 can have various shapes, for example, a trapezoidal groove, a rectangular groove, a dovetail groove, etc. (the drawings only show the embodiment in which the guide groove 51 is a trapezoidal groove). Correspondingly, the cross-section of the guide bar 52 can have various shapes corresponding to the guide groove 51.

[0063] In an optional embodiment of the present invention, the second component 42 drives the bearing component 70 to move by means of the limiting structure so that the bearing component 70 is separated from the first component 32 .

[0064] It should be noted that the above-mentioned limiting mechanism should be understood as a structure that can be driven by the second component 42 , or as a structure that at least limits the movement of the bearing component 70 in the moving direction of the second component 42 .

[0065] There may be various limiting structures with the above-mentioned features. For example, a wall structure may be provided on the periphery of the second component 42 so that when the bearing component 70 approaches the second component 42, it is restricted by the wall structure. For another example, the limiting structure may be a recessed groove formed on the second component 42, and the bottom of the bearing component 70 may be embedded in the recessed groove so that the bearing component 70 may move with the second component 42. For another example, a stop pin may be arranged on the periphery of the second component 42, and the bottom of the bearing component 70 may be located in the area covered by the stop pin so that the bearing component 70 may move with the second component 42.

[0066] In an optional embodiment of the present invention, Figures 1 to 7 As shown, the limiting structure includes a slot 61 (the slot 61 is difficult to show due to the angle of the figure, so the slot 61 is only marked by an indicator line, but according to the content recorded in the text, those skilled in the art should understand the position and function of the slot 61) and a plug post 62. The slot 61 is opened at the bottom of the bearing component 70, and the plug post 62 is set at a position corresponding to the slot 61 on the second component 42. When the bearing component 70 is close to the second component 42, the plug post 62 extends into the slot 61, so that the second component 42 can drive the bearing component 70 when moving.

[0067] The slot 61 and the plug post 62 have a variety of matching shapes. For example, the slot 61 is a circular slot (or a circular hole), a conical slot (or a conical hole, which is convenient for inserting the plug post 62 and has the function of correcting and positioning).

[0068] The first driving mechanism and the second driving mechanism may be of various types, for example, they may be driven by a screw, driven by a gear 412 and a rack 413 , driven by a telescopic cylinder 31 , and the like.

[0069] In an optional embodiment of the present invention, Figure 3 As shown, the first driving mechanism is a telescopic cylinder 31, which can be pneumatic or hydraulic. The telescopic cylinder 31 is installed on the rear side of the stand 20, and the head of the telescopic rod 311 of the telescopic cylinder 31 is connected to the first component 32 through the slat 312, so that when the telescopic rod 311 is extended, the first component 32 is driven to move upward, and when the telescopic rod 311 is retracted, the second component 42 is driven to move downward.

[0070] In an optional embodiment of the present invention, Figure 1 As shown, the second driving mechanism includes a rack 413, a gear 412 and a first motor 411. The rack 413 is arranged between two horizontal guide rails 44 and is parallel to the horizontal guide rails 44; the first motor 411 is arranged on the second component 42, and its output shaft faces downward. The gear 412 is mounted on the output shaft and forms a meshing state with the rack 413. The first motor 411 operates so that the gear 412 and the rack 413 form a meshing transmission, thereby driving the first component 32 to move along the horizontal guide rail 44.

[0071] The first component 32 may have a variety of structures. In a preferred embodiment, the first component 32 is a vertical plate-like body, the guide bar 52 is detachably or fixedly arranged on the front side of the first component 32 , and the slider 43 is fixed on the rear side of the first component 32 .

[0072] The second component 42 may have a variety of structures. In a preferred embodiment, the second component 42 is a horizontal plate-shaped body, and the plug post 62 is vertically arranged on the second component 42 .

[0073] The bearing member 70 can have a variety of structures. In a preferred embodiment, the bearing member 70 is formed by a bottom plate 71, side plates 72 disposed on both sides of the bottom plate 71, and a rear plate 73 disposed at the rear side of the bottom plate 71. The strip block 511 is disposed at the rear side of the rear plate 73, the guide groove 51 is located at the rear side of the bearing member 70, and the slot 61 is opened upward from the lower plate surface of the bottom plate 71.

[0074] In an optional embodiment of the present invention, the transfer device further comprises a feeding mechanism mounted on the carrying member 70 , and the workpiece 100 is horizontally moved in a direction perpendicular to the second member 42 by the feeding mechanism. The feeding mechanism provides a third transport track for the workpiece 100 .

[0075] like Figure 4 As shown, the feeding mechanism includes a transmission roller 82 arranged in sequence and arranged between two side plates 72 of the supporting component 70, a sprocket 83 arranged on the transmission roller 82, a chain meshing with the sprocket 83, and a second motor 81 that drives the sprocket 83 and meshes with the sprocket 83 and is fixed on the outer side of the side plate 72; wherein: the workpiece 100 is placed on the transmission roller 82, and the workpiece 100 is horizontally moved by the rotation of the transmission roller 82.

[0076] It should be noted that by changing the direction of the second motor 81, the transmission roller 82 can rotate in two directions, thereby enabling the workpiece 100 to move in two directions. This enables the feeding mechanism to enable the bearing component 70 to convey the workpiece 100 and to enable the bearing component 70 to receive the workpiece 100.

[0077] In an optional embodiment of the present invention, a buffer 90 is provided on the stand 20 and the conveyor 10, respectively, to buffer the movement of the first component 32 at the upper and lower travel limits. In this embodiment, the defect that the driving mechanism cannot make the first component 32 stop suddenly and the impact on the conveyor 10 and the stand 20 is alleviated by providing the buffer 90. The buffer 90 may be composed of a cylinder, a buffer rod extending out of the cylinder, and a spring provided in the cylinder.
