Description

Technical Field

[0001] This utility model relates to the field of plastic bottle conveying, and in particular to a bottle-picking robot structure. Background Technology

[0002] In the production and packaging of plastic bottles, the handling of plastic bottles needs to balance efficiency and bottle protection. Traditional manual handling is inefficient and labor-intensive, while early mechanical clamping solutions face multiple technical bottlenecks: rigid grippers are prone to scratches and damage to plastic bottles due to impact, and side-push drive structures are prone to gap jamming, causing bottles to fall or equipment damage; moreover, fixed-size grippers cannot be adapted to different bottle types.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN222453703U, a bottle-picking robot structure is disclosed, which uses a clamp to fix and clamp the bottle body. However, in the existing transposition and stacking process, the bottles are transported close together by the conveyor belt, while the boxes need to be placed in compartments. The current placement method uses the weight of the plastic bottles and the collision and squeezing between the box partitions to place them, which causes wear and tear between the plastic bottles and affects the quality of the bottle body. Utility Model Content

[0004] The purpose of this invention is to provide a bottle-retrieving robotic arm structure to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A bottle-retrieving robot structure includes a robotic arm for increasing power, a clamping mechanism for clamping the bottle, and a telescopic mechanism for adjusting the distance after retrieving the bottle. The telescopic mechanism is installed at the movable end of the robotic arm via a limiting mechanism, and a plurality of the clamping mechanisms are installed at the movable end of the telescopic mechanism. The limiting mechanism includes a hanger and a limiting frame. The limiting frame is fixedly connected to the lower end of the hanger and is a horizontal limiting rod. The telescopic mechanism includes an adjusting frame. Several adjusting frames are slidably connected to the limiting frame. The adjusting frames are connected to each other by a cross rod. One end of the limiting frame is fixedly connected to an adjusting cylinder. The piston rod of the adjusting cylinder is connected to the adjusting frame at one end by a pull rod. The center position of the cross rod is fixedly connected to the limiting frame by a center seat. The clamping mechanism includes shock-absorbing rods, and multiple rows of shock-absorbing rods are arranged corresponding to the adjusting frame. A connecting seat is fixed to the bottom of the shock-absorbing rod, and a clamping cylinder is installed at the center of the bottom of the connecting seat. Three clamping rods are arranged in a circular array on the outer side of the clamping cylinder. The center of the clamping rods is connected to the piston rod of the clamping cylinder through an opening and closing component. An adaptation component adapted to the shape of the bottle is installed on the inner side of the bottom of the clamping rods.

[0006] Preferably, the adapting component includes a V-shaped frame and an arc-shaped clamp. One end of the V-shaped frame is rotatably connected to the clamping rod, and the other end of the V-shaped frame has a V-shaped opening, with an arc-shaped clamp fixed at the opening. The inner side of the arc-shaped clamp has an arc-shaped structure.

[0007] Preferably, the inner side of the arc-shaped clamp has a semi-circular notch, and an anti-slip pad is bonded to the inner side of the arc-shaped clamp.

[0008] Preferably, the opening and closing assembly includes a pull rod, one end of which is connected to a connecting lug via a pin, the connecting lug being formed in the clamping rod, and the other end of the pull rod being connected to a central disc via a pin, the central disc being fixed to the piston rod end of the clamping cylinder.

[0009] Preferably, there are four crossbars, and four sets of clamping mechanisms are provided, with three clamps in each set.

[0010] Preferably, the shock absorber rod is bolted to and slidably connected to the adjusting frame.

[0011] Preferably, the crossbar is a scissor structure, and with the center seat as the center position, the two sets of adjustment frames on both sides expand and extend outward.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By coordinating the telescopic and clamping mechanisms, when plastic bottles need to be moved from one side of the conveyor belt to the stacking side, the opening and closing components can be controlled to quickly clamp the bottles in conjunction with the adapting components. The adapting components clamp the smooth bottles at multiple points to ensure clamping stability. The telescopic mechanism then adjusts the position of the plastic bottles synchronously, thereby enabling rapid movement and adaptation to the spacing of the plastic bottles in the stacking box. This improves work efficiency and prevents damage caused by collisions or excessive compression of the plastic bottles. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0018] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-7 As shown, a bottle-retrieving robot structure includes a robotic arm 1 for increasing power, a clamping mechanism 4 for clamping the bottle, and a telescopic mechanism 3 for adjusting the distance after retrieving the bottle. The telescopic mechanism 3 is installed on the movable end of the robotic arm 1 through a limiting mechanism 2, and several clamping mechanisms 4 are installed on the movable end of the telescopic mechanism 3. The limiting mechanism 2 includes a hanger 21 and a limiting frame 22. The limiting frame 22 is fixedly connected to the lower end of the hanger 21. The limiting frame 22 is a limiting rod with a horizontal structure. The telescopic mechanism 3 includes an adjusting frame 31. Several adjusting frames 31 are slidably connected to the limiting frame 22. The adjusting frames 31 are connected to each other through a cross rod 33. One end of the limiting frame 22 is fixedly connected to an adjusting cylinder 32. The piston rod of the adjusting cylinder 32 is connected to the adjusting frame 31 at one end through a pull rod 34. The center position of the cross rod 33 is fixedly connected to the limiting frame 22 through a middle seat 35. The clamping mechanism 4 includes shock-absorbing rods 41, and multiple rows of shock-absorbing rods 41 are provided corresponding to the adjusting frame 31. A connecting seat 42 is fixed to the bottom of the shock-absorbing rod 41. A clamping cylinder 44 is installed at the center of the bottom of the connecting seat 42. Three clamping rods 43 are arranged in a ring array on the outer side of the clamping cylinder 44. The center of the clamping rods 43 is connected to the piston rod of the clamping cylinder 44 through an opening and closing component 46. An adaptation component 45 adapted to the shape of the bottle is installed on the inner side of the bottom of the clamping rods 43.

[0019] In this embodiment, the adaptation component 45 includes a V-shaped frame 451 and an arc-shaped clamping plate 452. One end of the V-shaped frame 451 is rotatably connected to the clamping rod 43, and the other end of the V-shaped frame 451 has a V-shaped opening, and the arc-shaped clamping plate 452 is fixedly connected to the opening. The inner side of the arc-shaped clamping plate 452 has an arc-shaped structure. The single arc-shaped clamping plate 452 corresponds to the bottle mouth and bottle body of the plastic bottle, and the clamping force ensures the cooperation and clamping effect of the three sets of two points, thereby ensuring the stability of clamping the plastic bottle.

[0020] In this embodiment, a semi-circular notch is formed on the inner side of the arc-shaped clamp 452, and an anti-slip pad is bonded to the inner side of the arc-shaped clamp 452. The circular notch corresponds to the protruding position of the bottle mouth, which increases the contact area with the protruding position and the stability when clamping.

[0021] In this embodiment, the opening and closing assembly 46 includes a pull rod 461. One end of the pull rod 461 is connected to a connecting lug 462 via a pin. The connecting lug 462 is formed on the clamping rod 43. The other end of the pull rod 461 is connected to a central disc 463 via a pin. The central disc 463 is fixedly connected to the piston rod end of the clamping cylinder 44.

[0022] In this embodiment, four crossbars 33 are provided, and four sets of clamping mechanisms 4 are provided, with three in each set.

[0023] In this embodiment, the shock absorber 41 is bolted and slidably connected to the adjustable bracket 31, which facilitates the adjustment and fixing of the position of the clamping mechanism 4.

[0024] In this embodiment, the cross bar 33 is a scissor structure, with the center seat 35 as the center position, and the two sets of adjustable brackets 31 on both sides expand and extend outward.

[0025] Working principle: Adjust the initial position spacing and the final position spacing of the clamping mechanism 4 according to the spacing of the plastic bottles on the conveyor belt and the spacing of the plastic bottles in the corresponding stacking box. After the equipment is started, the mechanical arm 1 drives the limiting mechanism 2 and the telescopic mechanism 3 to the upper side of the conveyor belt. The telescopic mechanism 3 and the clamping mechanism 4 move down as a whole. After the clamping rod 43 and the middle seat 35 reach the height, the piston rod of the clamping cylinder 44 retracts and drives the clamping rod 43 and the adapting component 45 to clamp through the opening and closing component 46. Because of the arc-shaped surface of the adapting component 45, the six points around the plastic bottle quickly clamp and fix the bottle mouth position, thereby ensuring that the collision between the plastic bottles is reduced when they are lifted. The robotic arm 1 controls the plastic bottles to move to the stacked boxes. At this time, the adjusting cylinder 32 drives the cross bar 33 through the pull rod 34, thereby causing the four sets of adjusting frames 31 to extend and retract, which changes the spacing of the plastic bottles and puts them vertically into the boxes. Compared with the existing clamping equipment, when the plastic bottles are placed, they need to be squeezed between the bottles and the boxes to fall into the boxes because the plastic bottles are tilted and the spacing is not suitable. This solution reduces the transition collision and squeezing of the bottles, thereby ensuring the stability and work efficiency during the movement process and before and after the movement.
