[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0026] The embodiments of the present invention are as follows

[0027] like Figure 1 and Figure 2 As shown, the fully automatic flexible switching strand transfer device designed in the present invention includes three major parts: a bearing platform 1, a strand transfer support frame 2 and a strand transfer body 3.

[0028] A plurality of working surfaces for carrying workpiece assemblies are formed on the outside of the turning body 3. In this embodiment, the turning body 3 is applied to frame assembly operations. The entire turning body 3 is a rectangular frame structure with four working surfaces on the outside. Each working surface can reserve assembly holes of different specifications, and can correspond to the installation of four different types of frame assemblies.

[0029] The stock transfer support frame 2 is mounted on the carrier 1, and a stock transfer connection piece movably connected to the stock transfer body 3 is provided on the stock transfer support frame 2; the stock transfer body 3 is tilted and arranged directly above the stock transfer support frame 2, and can rotate freely around the central axis. The stock transfer support frame 2 is also provided with a stock transfer rotation mechanism, which is used to drive the stock transfer body 3 to rotate to adjust the assembly orientation of the workpiece assembly; the stock transfer support frame 2 is also provided with a stock transfer limit mechanism, which is used to limit the stock transfer body 3 after adjusting the assembly orientation of the workpiece assembly.

[0030] It should be noted that a plurality of strand support frames 2 can be arranged on the carrier platform 1 at the same time to install a plurality of strand bodies 3, thereby realizing the synchronous assembly operation of a plurality of component assemblies.

[0031] In this embodiment, after the frame assembly is assembled to one of the working surfaces, the stock rotation mechanism drives the stock body 3 to rotate to adjust the orientation of the frame assembly. Among them, the stock body 3 mainly drives the frame to flip 90 degrees to achieve the switching of the frame assembly in the vertical or horizontal direction, which is convenient for the subsequent installation of parts on the frame assembly. When the angle of the stock body 3 is adjusted, the position of the stock body 3 is limited by the stock limit mechanism to ensure that the stock body 3 is accurately adjusted to the position, and both accuracy and stability are guaranteed.

[0032] Specifically, Figure 1 As shown, the stock transfer connecting member includes a rotating shaft 31 arranged at both ends of the stock transfer body 3 and two bearing seats 4 mounted on the stock transfer support frame 2; a bearing that cooperates with the rotating shaft 31 is arranged in the bearing seat 4, and the rotating shaft 31 cooperates with the bearing to ensure that the stock transfer body 3 can rotate automatically.

[0033] Specifically, Figure 3 As shown, the stock transfer rotating mechanism includes a transmission gear 5, a rack 6 and a rack moving assembly 7; the transmission gear 5 is arranged on the rotating shaft 31 and meshes with the rack 6, and the rack moving assembly 7 can drive the rack 6 to move back and forth along the length direction to drive the transmission gear 5 to rotate, and the rotation direction of the rotating shaft 31 is changed by adjusting the moving direction of the rack 6 through the rack moving assembly 7, thereby controlling the stock transfer body 4 to rotate clockwise or counterclockwise to adjust the frame assembly to be assembled to the corresponding orientation.

[0034] Preferably, the rack moving assembly 7 includes a linear guide 71 and a first telescopic cylinder 72; the linear guide 71 is arranged along the length direction of the rack 6 and slides with it, and the linear guide 71 ensures that the rack 6 moves more linearly and with higher precision. The first telescopic cylinder 72 is connected to the rack 6 by driving, and the maximum telescopic distance of the first telescopic cylinder 72 can ensure that the rotating shaft 31 rotates one circle, thereby meeting the requirement that the rotating body 4 can be adjusted circumferentially.

[0035] Preferably, the stock conversion rotating mechanism further includes a bracket 8 arranged along one side of the rack 6, and a rack buffer 81 facing the end of the rack 6 is installed on the bracket 8, and the rack buffer 81 limits the limit position of the rack 6, and the rack buffer 81 performs flexible buffering when the rack 6 moves to the limit position. A rack position sensor 82 for detecting the position of the rack 6 is also provided on the bracket 8, which is used to detect the relative position of the rack 6 so as to accurately adjust the first telescopic cylinder 72.

[0036] Specifically, Figure 3As shown, the stock transfer limit mechanism includes a limit arm 9, a limit block 10 and a second telescopic cylinder 11; each working surface of the stock transfer body 3 is provided with a limit arm 9; a limit protrusion 101 matching the limit arm 9 is formed on the limit block 10; the second telescopic cylinder 11 is drivingly connected to the limit block 10, and is used to drive the limit block 10 to move back and forth so that the limit protrusion 101 is clamped or separated from the limit arm 9. When the stock transfer body 3 rotates, the limit arm 9 will rotate synchronously with the stock transfer body 3. Each time the stock transfer body 3 switches a working surface, the limit protrusion 101 is clamped to the limit arm 9 by the second telescopic cylinder 11 to fix the position of the stock transfer body 3, so as to avoid shaking when assembling parts of the frame assembly. When the orientation of the stock transfer body 3 needs to be adjusted again, the limit protrusion 101 can be separated from the limit arm 9 by the second telescopic cylinder 11.

[0037] Preferably, Figure 4 As shown, the limit block 10 is also provided with a limit arm buffer 102 arranged adjacent to the limit protrusion 101. When the rotation body 3 contacts the limit protrusion 101, the limit arm 9 is flexibly buffered by the set limit arm buffer 102 to prevent the limit arm 9 from directly and rigidly contacting the limit protrusion 101 to avoid shaking.

[0038] Specifically, the stock transfer limit mechanism also includes a lining plate 12 and a guide wheel 121; the lining plate 12 is arranged below the limit block 10 and extends along the moving direction of the limit block 10; the guide wheel 121 is set on the limit block 10 and rolls with the lining plate 12. During the movement of the limit block 10, the lining plate 12 is set to support the guide wheel 121, thereby reducing the travel resistance of the limit block 10 and providing a certain supporting force to ensure sufficient structural strength.

[0039] Preferably, Figure 2 and Figure 5 As shown, the stock transfer limit mechanism also includes a locking block 13, a positioning pin 14 and a third telescopic cylinder 15; a positioning hole 13a matching the positioning pin 14 is opened on the locking block 13; the third telescopic cylinder 15 is drivingly connected to the positioning pin 14, and is used to drive the positioning pin 14 to lock or separate the positioning hole 13a. When the orientation of the stock transfer body 3 is adjusted, the positioning pin 14 is driven by the third telescopic cylinder 15 to lock the positioning hole 13a to fix the position of the stock transfer body 3 to avoid shaking and ensure the stability of subsequent component assembly.

[0040] It should be noted that in this embodiment, the first telescopic cylinder 72, the second telescopic cylinder 11 and the third telescopic cylinder 15 can all adopt a cylinder assembly or a hydraulic cylinder assembly, the purpose of which is to provide linear thrust.

[0041] The working principle of the present invention is as follows:

[0042] (1) Assembling parts

[0043] Determine the working surface where the component assembly needs to be loaded, and use the first telescopic cylinder 72 to drive the rack 6 to move and synchronously drive the transmission gear 5 to rotate, so that the rotating shaft 31 drives the stock transfer body 3 to deflect the confirmed working surface to a position convenient for assembling the component assembly, and then the second telescopic cylinder 11 drives the limiting protrusion 101 to clamp with the upper limit arm 9 on the working surface for limiting, and at the same time the third telescopic cylinder 15 drives the positioning pin 14 to lock the positioning hole 13a to fix the position of the entire stock transfer body 3. After the position of the stock transfer body 3 is fixed, the component assembly that needs to be assembled with parts is assembled to a corresponding working surface of the stock transfer body 3 according to the corresponding specifications.

[0044] (2) Parts assembly work

[0045] After the component assembly is assembled, the staff can assemble the corresponding components according to the orientation of the component assembly at this time. When the orientation of the component assembly needs to be switched to facilitate the assembly of other components, the third telescopic cylinder 15 drives the positioning pin 14 to separate from the positioning hole 13a and release the lock; at the same time, the second telescopic cylinder 11 drives the limiting protrusion 101 to separate from the upper limit arm 9, so that the stock transfer body 3 returns to a free state, and the rack 6 is driven to move by the first telescopic cylinder 72, thereby continuing to adjust the orientation of the stock transfer body 3, so that the component assembly is switched to a suitable orientation, and the above process is repeated to fix the position of the stock transfer body 3, so that the component assembly can be freely switched in multiple orientations, so as to facilitate the subsequent assembly of components, and the overall assembly efficiency is also significantly improved.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
