Description

Technical Field

[0001] This utility model relates to the field of positioning structure technology, specifically to a packaging box feeding, positioning, and gripping mechanism. Background Technology

[0002] Traditional packaging boxes are often picked up and transported using pneumatic vacuum suction cups. However, the boxes are placed haphazardly, which affects the subsequent packaging process.

[0003] A patent with publication number CN212557027U is disclosed in the prior art. The solution includes a frame, an upper support frame is fixed on the top surface of the top plate of the frame, and vertical plates are fixed on the front walls of the left and right ends of the horizontal plate of the upper support frame. The two ends of the horizontal moving screw are hinged to the two vertical plates by bearings. A moving motor is fixed on the outer wall of one of the vertical plates. The moving motor drives the horizontal moving screw to rotate. A moving block is screwed onto the horizontal moving screw. It can automatically grab multiple cosmetic bottle packaging boxes that are pressed and aligned with each other, rotate them to stand upright, and move them to the packaging box and put them into the packaging box. It has a high degree of automation, good effect, and high efficiency.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] The existing packaging box feeding and positioning processes involve transferring the boxes to two separate machines, which increases the size of the equipment and fails to guarantee the efficiency of box feeding and positioning.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a packaging box feeding, positioning, and gripping mechanism. This addresses the problem that in traditional technologies, both feeding and positioning of packaging boxes involve transferring them to two separate devices, which increases the size of the equipment while failing to guarantee the efficiency of feeding and positioning.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The packaging box feeding, positioning, and gripping mechanism includes a movable frame, on which several sliding frames are arranged side-by-side along a horizontal direction. Each sliding frame has a vacuum suction cup fixedly attached to its lower end.

[0010] The adjacent sliding frames are connected by a fixed-distance structure.

[0011] As an optimized solution, a buffer plate is provided on the lower surface of the sliding frame along the vertical direction, and the buffer plate is provided with a clearance hole to avoid the vacuum suction cup.

[0012] As an optimized solution, the distance-fixing structure includes a distance-fixing plate located between adjacent sliding frames. One end of the distance-fixing plate is fixedly connected to one of the sliding frames by a fixing bolt. The other end of the distance-fixing plate has a horizontally opened distance-fixing sliding hole. A distance-fixing bolt is threadedly connected to another sliding frame. The distance-fixing bolt is slidably constrained within the distance-fixing sliding hole.

[0013] As an optimized solution, a distance cylinder is horizontally fixed to the bottom of the movable frame, and the telescopic end of the distance cylinder is connected to the sliding frame located at one of its outer ends.

[0014] As an optimized solution, the sliding frame at the other outer end is fixed to the movable frame using locking bolts.

[0015] As an optimized solution, a slide rail is horizontally fixed to the side wall of the movable frame, and a slide seat fixed to the slide rail is slidably constrained on the sliding frame.

[0016] As an optimized solution, spring telescopic rods are vertically fixed to the lower ends of the sliding frame near the four corners, and the lower ends of the spring telescopic rods are fixed to the upper surface of the buffer plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The mobile frame can move along the conveyor, lift, and lateral under the action of the main frame. Under normal conditions, the fixed-distance cylinder is in the retracted state. Several sliding frames approach each other, the mobile frame descends, and the vacuum suction cup under each sliding frame can adsorb the packaging box below. Then the mobile frame rises, lifting the adsorbed packaging boxes. Then the fixed-distance cylinder extends, driving the outermost sliding frame to move to one side. The outermost sliding frame uses the fixed-distance sliding holes on the fixed-distance plate to ensure the distance between two adjacent sliding frames in turn, realizing the quick gripping of several packaging boxes and the quick separation and positioning of several packaging boxes.

[0019] A high-precision, high-efficiency, multi-size adaptive, and highly stable packaging box feeding, positioning, and gripping mechanism has been developed, solving the problems of positioning deviation, cumbersome model changeover, and dynamic interference in existing technologies.

Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] like Figure 1 and Figure 2 As shown, the packaging box loading, positioning, and gripping mechanism includes a movable frame 1, on which several sliding frames 2 are arranged side by side along the horizontal direction. A vacuum suction cup 3 is fixedly mounted side by side at the lower end of each sliding frame 2.

[0026] Adjacent sliding frames 2 are connected by a fixed-distance structure.

[0027] A buffer plate 4 is provided on the lower surface of the sliding frame 2 along the vertical direction, and a clearance hole 5 is provided on the buffer plate 4 to avoid the vacuum suction cup 3.

[0028] The distance-fixing structure includes a distance-fixing plate 9 located between adjacent sliding frames 2. One end of the distance-fixing plate 9 is fixedly connected to one side of the sliding frame 2 by a fixing bolt 10. The other end of the distance-fixing plate 9 is horizontally provided with a distance-fixing sliding hole 11. A distance-fixing bolt 12 is threadedly connected to another sliding frame 2. The distance-fixing bolt 12 is slidably constrained in the distance-fixing sliding hole 11.

[0029] A fixed-distance cylinder 15 is horizontally fixed to the bottom of the movable frame 1, and the telescopic end of the fixed-distance cylinder 15 is connected to the sliding frame 2 located at one of its outer ends.

[0030] The sliding frame 2 at the other outer end is fixed to the movable frame 1 by locking bolts 13.

[0031] A slide rail 8 is horizontally fixed to the side wall of the movable frame 1, and a slide seat fixed to the slide rail 8 is slidably mounted on the sliding frame 2.

[0032] Spring telescopic rods 6 are vertically fixed to the lower ends of the sliding frame 2 near the four corners, and the lower ends of the spring telescopic rods 6 are fixed to the upper surface of the buffer plate 4.

[0033] The upper end of the movable frame 1 is fixed with a vacuum generator 14 connected to the vacuum suction cup 3. Since the connection structure is common in daily life and is common knowledge to those skilled in the art, it will not be described in detail here.

[0034] The working principle of this device is as follows:

[0035] The movable frame 1 can move along the conveyor lifting and lateral movement under the action of the frame. Under normal conditions, the fixed distance cylinder 15 is in the retracted state. Several sliding frames 2 are close to each other. The movable frame 1 descends, and the vacuum suction cup 3 under each sliding frame 2 can adsorb the packaging box 7 below. Then the movable frame 1 rises and lifts the adsorbed packaging box 7. Then the fixed distance cylinder 15 extends and drives the outermost sliding frame 2 to move to one side. The outermost sliding frame 2 uses the fixed distance sliding hole 11 on the fixed distance plate 9 to ensure the distance between two adjacent sliding frames 2 in turn, so as to realize the quick clamping of several packaging boxes 7 and the quick separation and positioning of several packaging boxes 7.

[0036] A high-precision, high-efficiency, multi-size adaptive, and highly stable packaging box 7 feeding, positioning, and gripping mechanism has been developed, solving the problems of positioning deviation, cumbersome model changeover, and dynamic interference in existing technologies.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
