Technical Field

[0001] The present invention relates to the technical field of fixture switching, and in particular to a special-shaped fixture switching device. Background Art

[0002] In automotive screen applications, the demand for special-shaped curved screens continues to increase. During the production process of special-shaped curved screens, the product will be subjected to forces from the vertical direction, so every point of the product is required to have support from below. For this reason, special-shaped jigs are prepared for the production of special-shaped curved screens.

[0003] Due to the different types of special-shaped curved screens produced, there are also many types of special-shaped jigs. During the production process, it is often necessary to switch between different special-shaped jigs to meet production requirements. In the prior art, clamps are generally used to achieve the switching of special-shaped jigs. However, in the process of the clamp grabbing the special-shaped jig for transportation, the special-shaped jig is easily dropped from the clamp, causing damage to the special-shaped jig, resulting in the inability to continue production, affecting production efficiency.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0046] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0047] According to an embodiment of the present invention, a switching device for a special-shaped fixture 24 is provided, comprising: a frame 1, a grasping component 2 and an auxiliary component.

[0048] Specifically, the gripping assembly 2 is movably arranged on the frame 1, and a movable clamping claw structure 3 is arranged on the gripping assembly 2. When the gripping assembly 2 moves to a specified position, the clamping claw structure 3 has a state of moving to the top of the special-shaped jig 24 and grasping the special-shaped jig 24, or the clamping claw structure 3 has a state of releasing the special-shaped jig 24 and placing the special-shaped jig 24 at a specified position. The auxiliary assembly is arranged on the gripping assembly 2, and the auxiliary assembly includes a plurality of negative pressure structures arranged along the extension direction of the special-shaped jig 24, one end of the negative pressure structure is constructed to be parallel to the special-shaped surface of the special-shaped jig 24 and to fit the special-shaped surface of the special-shaped jig 24 when the clamping claw structure 3 grasps the special-shaped jig 24, and the negative pressure structure has a through hole, one end of the through hole faces the special-shaped surface, and the other end of the through hole is connected to the vacuum structure.

[0049] In this embodiment, the grabbing assembly 2 is arranged on the frame 1, and a drag chain assembly is arranged on the frame 1. The grabbing assembly 2 is connected to the drag chain assembly, so that it can move on the frame 1. The grabbing assembly 2 can move in the horizontal direction and in the direction of gravity through the drag chain assembly. A lifting structure is arranged on the grabbing assembly 2, and the lifting structure is connected to the clamping claw structure 3 so that the clamping claw structure 3 can move in the direction of gravity. The grabbing assembly 2 can be moved to a specified position through the drag chain assembly, and the special-shaped fixture 24 is moved to the specified position through the conveyor belt. The specified position is the clamp on the conveyor belt. The claw structure 3 can grasp the position of the special-shaped jig 24 or the position where the special-shaped jig 24 is placed.

The upper end of the negative pressure structure is rotatably arranged on the slider 5. The negative pressure structure can be moved along the guide rails 4 toward the direction close to the clamping structure 3 or away from the clamping structure 3 through the slider 5. A first fastener 6 is arranged on the slider 5, and the first fastener 6 can fix the slider 5 on the guide rail 4 to limit the slider 5.

[0056] Preferably, in this embodiment, two negative pressure structures are provided on each slider 5 , and a plurality of sliders 5 are provided on the guide rail 4 . The number of the sliders 5 can be determined by the number of the negative pressure structures.

[0057] Specifically, the first fastener 6 is a fastening knob.

[0058] It should be noted that the negative pressure structure can move along the guide direction of the guide rail 4 through the slider 5, so as to adjust the distance between adjacent negative pressure structures and the distance between the negative pressure structure and the clamping claw structure 3, so as to better match special-shaped fixtures 24 of different sizes.

The first guide rod 10 can play a guiding role. A second fastener 11 is provided on the first guide rod 10. The second fastener 11 is a tightening knob. By tightening the tightening knob, the slide plate 8 can be tightly fitted with the slide groove 7 to prevent the slide plate 8 from moving, thereby realizing the limitation of the slide plate 8. The negative pressure structure is rotatably connected to the lower end of the slide plate 8.

[0061] It should be noted that the slide plate 8 slides along the slide groove 7 to adjust the height of the negative pressure structure, and then adjust the distance between the negative pressure structure and the special-shaped fixture 24, which effectively improves the practicality of the negative pressure structure and better matches the special-shaped fixtures 24 of different sizes.

[0063] The second guide rod 16 is provided with a third fastener 17, which is a tightening knob. The third fastener 17 ... A through hole is provided in the suction cup 14 , and the lower end of the suction cup 14 is fitted with the special-shaped surface of the special-shaped fixture 24 . The vacuum structure is connected to the upper end of the suction cup 14 through a pipeline and communicates with the through hole.

[0064] Specifically, one end of the suction cup 14 that fits the special-shaped surface of the special-shaped fixture 24 is a flexible structure. Preferably, the flexible structure is silicone, so as to avoid scratching the special-shaped surface of the special-shaped fixture 24.

[0065] It should be noted that, by providing the second guide rod 16 and the second waist-shaped hole 15 , the position of the suction cup 14 can be better adjusted, which effectively improves the practicality of the suction cup 14 and further better matches special-shaped fixtures 24 of different sizes.

[0066] like Figure 2 and Figure 4 As shown, in some embodiments, a circular through hole 18 is opened at the lower end of the skateboard 8, and a circular turntable 19 is arranged at one end of the rotating plate 12.

The fourth fastener 21 is a tightening knob. The movable gap 20 is reduced by tightening the tightening knob, so that the circular through hole 18 contracts inward to squeeze the turntable 19, thereby achieving the limitation and fixation of the turntable 19.

[0068] Specifically, Figure 2 and Figure 4 As shown, the slide plate 8 has markings arranged along the circumference of the circular through hole 18 , and a pointer is arranged on the turntable 19 , the pointer points to the markings, and the pointer rotates along with the turntable 19 .

When the special-shaped jig 24 needs to be switched, the grabbing assembly 2 is moved to the designated position through the drag chain assembly, and the clamping claw structure 3 moves to above the designated position to grab the special-shaped jig 24 located at the designated position. Then the grabbing assembly 2 is moved to above the switching station 23 where the special-shaped jig 24 is not placed through the drag chain assembly, and the clamping claw structure 3 moves vertically downward to place the special-shaped jig 24 at the switching station 23. Then the grabbing assembly 2 is moved to above the switching station 23 of the special-shaped jig 24 that needs to be switched, and the clamping claw structure 3 moves vertically downward to grab the special-shaped jig 24 that needs to be switched. After the clamping claw structure 3 grabs the special-shaped jig 24 that needs to be switched, the grabbing assembly 2 is moved to the designated position through the drag chain assembly, and the clamping claw structure 3 moves vertically downward to place the switched special-shaped jig 24 at the designated position.

[0071] In other embodiments, three, four or other numbers of switching stations 23 may be provided on the placement platform 22 .

[0072] It should be noted that, by setting the switching station 23, the placement platform 22 can store more special-shaped jigs 24, and the special-shaped jigs 24 can be quickly switched, which is beneficial to improving production efficiency.

[0073] like Figure 3 , Figure 5 and Figure 6As shown, in some embodiments, the clamping structure 3 includes a clamping bracket 25, a pair of clamping jaws 26 arranged relatively at intervals, and a driving structure 27.

Any clamping jaw 26 can move along the sliding bar 28 in the direction of approaching or away from the other clamping jaw 26. When any clamping jaw 26 moves in the direction of approaching the other clamping jaw 26, it can grab the special-shaped fixture 24, and when any clamping jaw 26 moves in the direction of moving away from the other clamping jaw 26, it can release the special-shaped fixture 24. The driving structure 27 is a cylinder, which is arranged at the bottom of the clamping bracket 25. The cylinder is fixedly connected to the pair of clamping jaws 26 to drive the pair of clamping jaws 26 to move. A latch 29 is arranged on the clamping jaw 26, and a socket 30 is opened on the side of the special-shaped fixture 24.

[0079] In this embodiment, support plates 33 are provided on the left and right sides of the switching station 23, and vacuum suction holes (not shown) are provided in the support plates 33. One end of the vacuum suction holes is connected to the vacuum structure through a pipeline, and the other end of the vacuum suction holes is located on the upper end surface of the support plate 33. After the special-shaped jig 24 is placed on the support plate 33, the bottom surface of the special-shaped jig 24 is fitted with the upper end surface of the support plate, and the vacuum suction holes will generate suction to adsorb the special-shaped jig 24 on the support plate 33.

[0080] It should be noted that a vacuum suction hole is provided on the support plate 33, and the vacuum suction hole can adsorb the special-shaped fixture 24 on the support plate 33, effectively preventing the special-shaped fixture 24 from moving and preventing the special-shaped fixture 24 from being skewed due to movement and the clamp 26 from being unable to grasp.

[0081] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
