[0020] Any process or method description in the flowchart or otherwise described herein may be understood to represent a module, fragment or portion of code that includes one or more executable instructions for implementing the steps of a specific logical function or process, and the scope of the preferred embodiments of the present invention includes alternative implementations in which functions may not be performed in the order shown or discussed, including performing functions in a substantially simultaneous manner or in the reverse order depending on the functions involved, which should be understood by technicians in the technical field to which the embodiments of the present invention belong.

[0021] like Figure 1 and Figure 2As shown, the utility model provides a flexible storage position switching slide, including a frame 1; a guide rail mechanism 2, horizontally installed on the frame 1, including a transverse guide rail 23 and a longitudinal guide rail arranged perpendicular to the transverse guide rail 23; a slide plate 3, slidably installed on the guide rail mechanism 2; a traction mechanism 4, installed on the frame 1, and driving the slide plate 3 to slide along the guide rail mechanism 2; a reversing mechanism 5, installed on the guide rail mechanism 2, and driving the slide plate 3 to shift and reverse between the transverse guide rail 23 and the longitudinal guide rail.

[0022] The guide rail mechanism 2, the slide plate 3 and the traction mechanism 4 can be combined into a conventional conveying slide, and the slide plate 3 slides along the guide rail mechanism 2 on the conveying slide. The reversing mechanism 5 added in the present application on this basis provides the ability of vertical reversal on the straight guide rail mechanism 2. The reversing mechanism 5 is arranged in the middle or at the end of the guide rail mechanism 2, which can greatly increase the ability of flexible arrangement of the storage position of the switching slide, greatly improve the expandability and design possibility of the entire switching slide, and can be designed into different forms according to the design needs of the flexible storage position through the cooperation of the guide rail mechanism 2 and the reversing mechanism 5, including a straight slide, a cross slide, a T-shaped slide or an H-shaped slide, etc.

[0023] This highly efficient and scalable combined horizontal and vertical movement mode can adapt to the precise switching of a variety of products and can be applied to the production integration of multi-model or multi-process white body welding.

[0024] The specific use process takes a straight-line slide as an example to switch between the A / B positions. The slide is provided with a working position and two stop positions. The traction mechanism 4 is used to drive the A slide 3 to move. After moving from the switching position to the working position, it stops moving. The frame 1 is provided with a locking mechanism to lock the slide 3. The locking mechanism is a common mechanism form in the conveying device, so it will not be repeated. After the A slide 3 is locked in the working position, the tooling fixture on the slide 3 can be operated. When the A slide 3 is finished using, it is necessary to switch the B slide 3. The locking mechanism of the A slide 3 is released, and the A slide 3 is removed. The traction mechanism 4 drives the B slide 3 to slide into the working position for the corresponding operation. The two stop positions are set for the A slide 3 and the B slide 3 to switch the working positions, so that the continuous switching of different slides 3 on the working position can be realized.

[0025] like Figure 3As shown, the traction mechanism 4 includes a traction rail 6, a traction slider 7 slidably mounted on the traction rail 6, a traction frame 8 arranged on the traction slider 7 and a traction rack 9 parallel to the traction rail 6, a traction drive motor 10 is installed on the traction frame 8, a traction gear 11 meshing with the traction rack 9 is installed at the output end of the traction drive motor 10, and a quick connection mechanism 12 for quickly connecting or quickly disengaging with the slide 3 is provided on the traction frame 8.

[0026] The traction frame 8 can move along the traction rail 6 under the rotation of the traction drive motor 10. The traction drive motor 10 is a servo motor. The traction rack 9 and the traction gear 11 are precisely matched and reliable, and the driving force is strong, so the traction frame 8 can be accurately controlled. When the slide plate 3 needs to be driven, the slide plate 3 can be quickly connected to the traction frame 8 through the quick connection mechanism 12, so that the traction mechanism 4 can be quickly connected to the slide plate 3. The traction mechanism 4 can drive the slide plate 3 to move. When the slide plate 3 needs to be replaced, or the slide plate 3 needs to be withdrawn for transmission and there is no circulation and transportation demand, the quick connection mechanism 12 can be quickly disengaged to achieve the separation of the traction frame 8 and the slide plate 3. The traction mechanism 4 can drive other slide plates 3 with circulation and transportation demand. This method is different from the method of setting a power mechanism on the conveying slide plate 3. On the one hand, it avoids the waste of the power mechanism on the slide plate 3 in the parking position. On the other hand, it can greatly simplify the structure of the slide plate 3, so that the space on the slide plate 3 can be fully reserved for the working device.

[0027] like Figure 5 As shown, a walking wheel mechanism 13 is installed on the skateboard 3, and the walking wheel mechanism 13 includes a walking wheel fixing frame 14 fixed to the skateboard 3, a walking wheel rotating frame 15 rotatably installed on the walking wheel fixing frame 14, and a walking roller 16 rollingly installed at the bottom of the walking wheel rotating frame 15, and the walking roller 16 rolls along the top surface of the guide rail of the guide rail mechanism 2. Two walking guide wheels 17 that can roll against the side walls of the guide rail of the guide rail mechanism 2 are also arranged at the bottom of the walking wheel rotating frame 15; the two walking guide wheels 17 are arranged separately and at intervals, and the two walking guide wheels 17 are arranged on the same side or both sides of the guide rail of the guide rail mechanism 2.

[0028] like Figure 4 and Figure 6 As shown, the reversing mechanism 5 includes a fixed reversing base 18, a reversing chassis 19 rotatably mounted on the reversing base 18, and a reversing cylinder 20 driving the reversing chassis 19 to rotate, a reversing rail 21 is provided on the top surface of the reversing chassis 19, a cylinder body of the reversing cylinder 20 is hingedly arranged on the reversing base 18, and a piston rod end of the reversing cylinder 20 is hingedly arranged on the reversing chassis 19.

[0029] There are four walking wheel mechanisms 13, which are respectively arranged around the bottom of the skateboard 3, and the skateboard 3 slides on the paired guide rails of the guide rail mechanism 2 through the four walking wheel mechanisms 13; there are four reversing mechanisms 5, which are arranged on the guide rail mechanism 2 corresponding to the positions of the walking wheel mechanisms 13; a transition rail 22 is arranged between two adjacent reversing mechanisms 5; the transition rail 22 is respectively arranged in the transverse direction or the longitudinal direction, and is combined with the reversing rail 21 to dock and extend the transverse guide rail 23 or the longitudinal guide rail.

[0030] The sliding of the skateboard 3 on the guide rail mechanism 2 can be achieved through the walking wheel mechanism 13. The walking wheel rotating frame 15 in the walking wheel mechanism 13 can rotate on the walking wheel fixed frame 14. The walking roller 16 arranged below the walking wheel rotating frame 15 can roll on the guide rail surface of the guide rail mechanism 2, which can realize the movement of the skateboard 3. However, since the walking wheel rotating frame 15 is in a rotatable state, the walking roller 16 cannot determine the direction of rolling. Therefore, a walking guide wheel 17 is also provided. The walking guide wheel 17 is mainly formed by being attached to the side wall of the guide rail of the guide rail mechanism 2. Since the walking guide wheel 17 is fixedly arranged on the walking wheel rotating frame 15, the two walking guide wheels 17 attached to the side wall of the guide rail on the guide rail mechanism 2 can limit the freedom of the walking wheel rotating frame 15 in the rotation direction. In this way, the rotation state of the walking wheel rotating frame 15 can be limited, and it can be ensured that the walking roller 16 always rolls along the guide rail surface.

[0031] The reversing mechanism 5 can provide the guide rail mechanism 2 with flexible layout capabilities and rich expansibility. The guide rail mechanism 2 can be expanded horizontally and vertically. The reversing mechanism 5 can switch the rolling direction of the walking wheel mechanism 13 online, and the movement state of the slide plate 3 on the horizontal guide rail 23 and the longitudinal guide rail can be switched by the extension and retraction of the reversing cylinder 20.

[0032] The specific operation method is as follows: taking the transverse guide rail 23 turning to the longitudinal guide rail as an example, when the slide plate 3 moves on the transverse guide rail 23, the walking guide wheel 17 rolls against the side wall of the guide rail mechanism 2, the walking wheel rotating frame 15 is limited in the rotation direction, and the walking roller 16 rolls along the transverse direction on the transverse guide rail 23, which can drive the slide plate 3 to move horizontally along the transverse guide rail 23 normally. When it is necessary to shift to the longitudinal guide rail, the walking wheel mechanism 13 rolls onto the reversing mechanism 5. At this time, the reversing mechanism 5 sets the position state of the reversing rail 21 in the colinear direction of the transverse guide rail 23, that is, the walking wheel mechanism 13 moves from the transverse guide rail 23 to the transversely arranged reversing rail 21, and the walking guide wheel 17 fits against the side wall of the reversing rail 21, and then, in the reversing Driven by the cylinder 20, the reversing base 18 rotates to adjust the reversing rail 21 from a horizontal position to a longitudinal position. Since the walking wheel rotating frame 15 is rotatable, the rotation drive of the reversing rail 21 will drive the walking guide wheel 17 fixed on the walking wheel rotating frame 15 to rotate, thereby changing the rolling direction of the walking roller 16 from horizontal to longitudinal. At this time, the reversing rail 21 and the longitudinal transition rail 22 are docked, and the longitudinal reversing rail 21, transition rail 22 and longitudinal guide rail form a complete continuous track. At this time, since the walking guide wheel 17 is in contact with the side wall of the reversing rail 21, this will maintain the walking wheel mechanism 13 moving in the longitudinal direction, thereby realizing the switching of the slide plate 3 from moving on the horizontal guide rail 23 to moving on the longitudinal guide rail.

[0033] like Figure 7 and Figure 8 As shown, the quick-connect mechanism 12 includes a quick-connect seat 25 and a quick-connect buckle 26, the quick-connect seat 25 is installed with a transversely arranged connecting pin 27, the quick-connect buckle 26 includes a quick-connect mounting frame 28, and the quick-connect mounting frame 28 is respectively provided with a first hinge point 29 and a second hinge point 30 at both ends, a quick-connect cylinder 31 is hingedly installed on the first hinge point 29, and a connecting plate 32 is hingedly installed on the second hinge point 30, the piston rod end of the quick-connect cylinder 31 is hinged on the connecting plate 32, the quick-connect cylinder 31 telescopically drives the connecting plate 32 to rotate along the second hinge point 30, and the connecting plate 32 is provided with a bayonet 33 that cooperates with the connecting pin 27.

[0034] The quick-connect mounting frame 28 can be pushed to rotate back and forth along the second hinge point 30 by the extension and retraction of the quick-connect cylinder 31, so that the bayonet 33 on the connecting plate 32 can be engaged and disengaged with the connecting pin 27. When the piston rod of the quick-connect cylinder 31 is extended and the bayonet 33 is rotated downward, the bayonet 33 can buckle the connecting pin 27, and the quick-connect buckle 26 and the quick-connect seat 25 are connected to form a whole. When disengagement is required, the piston rod of the quick-connect cylinder 31 is retracted, the bayonet 33 is rotated upward, and the bayonet 33 is lifted off the connecting pin 27, so that quick disengagement can be achieved.

[0035] A limit block 34 is provided on the quick-connect mounting frame 28. When the bayonet 33 is engaged with the connecting pin 27, the limit block 34 can limit the connecting plate 32 from continuing to rotate toward the connecting pin 27. The limit block 34 can effectively prevent the connecting plate 32 from continuing to rotate under the push of the cylinder after the engagement is completed, thereby preventing the connecting plate 32 from continuously applying unfavorable additional pressure to the connecting pin 27, and preventing the connecting pin 27 from being deformed or other defects caused by the action of external force for a long time, thereby extending the service life of the quick-connect seat 25 and the quick-connect buckle 26.

[0036] The side of the frame 1 is provided with an industrial medium connector 35, and the slide plate 3 is provided with an industrial medium interface 36 that is quickly connected to the industrial medium connector 35. The industrial medium connector 35 can provide basic working conditions for the operating device on the slide plate 3. After being moved to the working position and locked, the industrial medium connector 35 is docked with the industrial medium interface 36, and can provide power sources such as electricity and gas to the fixture on the slide plate 3. After the fixture is in the working position, operations such as welding can be performed. When the work is completed and the slide plate 3 at the working position needs to be moved to the stop position, it only needs to cut off the industrial medium connector 35 and the industrial medium interface 36 to perform the corresponding transfer operation, which is convenient and fast.
