Description

Technical Field

[0001] This utility model relates to the field of wall panel gripping machines, and more particularly to a wall panel gripping machine with an anti-slip textured suction cup. Background Technology

[0002] In the construction industry, wall panel installation is a common and crucial process. To improve construction efficiency and reduce labor intensity, wall panel grabbers are widely used as specialized automated or semi-automated equipment. Wall panel grabbers typically use gripping devices mounted on a robotic arm or frame to grab, transport, and place wall panels. In prefabricated building and decoration construction, efficient and damage-free handling of wall panels is a key factor restricting construction schedule and quality. Existing wall panel grabbers mostly employ rigid hooks or simple vacuum suction cups for single-point lifting.

[0003] The aforementioned device has the following drawbacks: the suction cup layout of the existing equipment cannot be adjusted in real time according to the length and width of the wall panel, resulting in the suction point being concentrated in the middle. Large wall panels are prone to deflection, cracking, or even falling off due to the suspension at both ends. Furthermore, the contact between the suction cup and the wall panel is rigid, lacking buffering, resulting in a large impact force at the moment of lowering. The anti-slip textured surface is easily scratched, and the failure of the seal may lead to the risk of the panel falling off. Therefore, a wall panel gripping machine with anti-slip textured suction cups is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wall panel gripping machine with anti-slip textured suction cups, which aims to improve the problems of large-size wall panel deformation caused by the non-adjustable suction cup layout, surface scratches caused by rigid impact, and poor adaptability of auxiliary support in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wall panel gripping machine with anti-slip textured suction cups, comprising a support frame, a suction cup assembly provided at the front end of the lower surface of the support frame, two sets of auxiliary components provided on both the left and right surfaces of the support frame, a support base fixedly installed at the axis of the upper surface of the support frame, a load-bearing column fixedly installed on the upper surface of the support base, the suction cup assembly comprising an adjusting frame, an adjusting block slidably connected in the grooves of the front and rear surfaces of the adjusting frame, a piston column fixedly installed on the lower surface of the adjusting block, a telescopic rod fixedly connected to the bottom end of the piston column, a spring sleeved on the outer wall of the telescopic rod, a suction cup frame detachably connected to the bottom of the telescopic rod, a slider slidably connected to the inner wall of the adjusting frame, and a fixing frame fixedly connected to the lower surface of the slider.

[0006] As a further description of the above technical solution: the auxiliary component includes an auxiliary seat, the left surface of which is detachably connected with multiple sets of fixing bolts, the lower surface of which is threadedly connected with a lifting rod, the lower surface of which is fixedly connected with a positioning plate, and the lower surface of which is fixedly connected with a suction cup strip.

[0007] As a further description of the above technical solution: two sets of moving grooves are provided on the left and right ends of the upper surface of the fixed frame, two sets of limiting blocks are fixedly connected to the left and right ends of the fixed frame, the moving blocks are slidably connected to the inner wall of the moving grooves, and the bottom end of the moving blocks is detachably connected to an auxiliary suction cup.

[0008] As a further description of the above technical solution: both the left and right ends of the suction cup strip are detachably connected to two sets of protective pads.

[0009] As a further description of the above technical solution: the interior of the auxiliary suction cup is configured as a hollow structure, and the outer wall of the auxiliary suction cup is configured as a rounded corner structure.

[0010] As a further description of the above technical solution: the top end of the spring is fixedly connected to the telescopic end of the telescopic rod, and the bottom end of the spring is fixedly connected to the top end of the fixing frame.

[0011] As a further description of the above technical solution: the adjustment frame is fixedly installed on the front end of the lower surface of the support frame.

[0012] As a further description of the above technical solution: the auxiliary seat is slidably connected in the grooves on the left and right surfaces of the outer wall of the support frame.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the three-way stepless adjustment of the equipment is realized by the mutual cooperation between the adjustment block, slider, moving block and other components in the equipment through the connection relationship. The auxiliary suction cup array can be optimized in real time according to the length and width of the wall panel. With the flexible buffer of spring and telescopic rod and hollow rounded corner suction cup, multi-point uniform adsorption, impact prevention, anti-slip texture sealing are achieved to avoid local stress concentration and surface scratches on the wall panel.

[0015] 2. In this utility model, by utilizing the mutual cooperation between the auxiliary seat, lifting rod, and fixed frame and other components in the equipment, the suction cup strip is matched with the wall panel thickness and ground undulation in real time. The four sets of symmetrical arrangements form edge line contact support, which distributes the weight, suppresses bending, and is combined with protective pads to prevent bumps and collisions, significantly improving the safety and stability of handling large-size and heavy wall panels.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 3This utility model provides an embodiment of a wall panel grabbing machine with anti-slip textured suction cups, including a support frame 1. The support frame 1 serves as the overall machine skeleton, supporting the suction cup assembly 2, auxiliary components 3, support base 4, and load-bearing columns 5, ensuring the overall structural rigidity and stability, and transferring the loads of each functional module to external handling equipment. The suction cup assembly 2 is provided at the front end of the lower surface of the support frame 1. The suction cup assembly 2 is located at the front end of the lower surface of the support frame 1 and grabs multiple wall panels at once through vacuum adsorption, achieving reliable pickup and release. It is the core execution unit of the entire wall panel grabbing machine. Two sets of auxiliary components are provided on both the left and right surfaces of the support frame 1. 3. Auxiliary components 3 are symmetrically arranged on the left and right sides of the support frame 1, in a total of four sets, to provide additional adsorption points and support force when gripping large or heavy wall panels, preventing the wall panels from bending, deforming or falling off in parts. A support seat 4 is fixedly installed at the center of the upper surface of the support frame 1. The support seat 4 serves as a transition component between the load-bearing column 5 and the support frame 1, dispersing the bending moment and torque transmitted by the load-bearing column 5 and improving the connection strength. The load-bearing column 5 is fixedly installed on the upper surface of the support seat 4. The load-bearing column 5 is vertically installed on the upper end of the support seat 4 and is used to connect with an external robot arm or gantry crane to realize the lifting, translation and rotation of the whole machine, and to bear the weight of the whole machine and the load of the wall panel.

[0024] Reference Figure 2 - Figure 4The suction cup assembly 2 includes an adjustment frame 21, which is fixedly installed on the front end of the lower surface of the support frame 1. The adjustment frame 21 is fixedly installed on the front end of the lower surface of the support frame 1, providing an installation reference for the suction cup assembly 2. The groove structure on its front and rear surfaces is used to guide the linear displacement of the adjustment block 22, realizing rapid coarse adjustment of the front and rear position of the suction cup. The adjustment block 22 is slidably connected in the grooves on the front and rear surfaces of the adjustment frame 21. The adjustment block 22 is slidably embedded in the groove of the adjustment frame 21. Its front and rear position can be changed manually or electrically, thereby driving the piston column 23 below and the suction cup frame 26 to move synchronously to adapt to wall panels of different lengths. The piston column 23 is fixedly installed on the lower surface of the adjustment block 22. The upper end of the piston column 23 is fixedly connected to the adjustment block 22, and the lower end is connected to the telescopic rod 24. The piston column 23 is internally equipped with a piston column 23. The air passage is used to transmit the negative pressure of the vacuum source to the suction cup holder 26 and the auxiliary suction cup 284, and also provides axial rigid guidance. A telescopic rod 24 is fixedly connected to the bottom end of the piston column 23. The telescopic rod 24 is sleeved on the bottom end of the piston column 23 and can move up and down slightly under the action of the spring 25 and the weight of the wall panel, forming a flexible buffer to avoid rigid impact between the suction cup and the wall panel and improve the adsorption reliability. A spring 25 is sleeved on the outer wall of the telescopic rod 24. The top end of the spring 25 is fixedly connected to the telescopic end of the telescopic rod 24, and the bottom end of the spring 25 is fixedly connected to the top end of the fixing frame 28. The spring 25 is sleeved on the outer wall of the telescopic rod 24, with the top end fixed to the telescopic end of the telescopic rod 24 and the bottom end fixed to the top end of the fixing frame 28, to provide a rebound force so that the suction cup holder 26 automatically returns to its original position when not adsorbing. The telescopic rod 24 is detachably connected to a suction cup frame 26 at its bottom. The suction cup frame 26 acts as a negative pressure distributor, evenly distributing vacuum to each auxiliary suction cup 284. It also allows for quick assembly and disassembly of suction cups of different sizes, enabling modular maintenance. A slider 27 is slidably connected to the inner wall of the adjusting frame 21. The slider 27 slides laterally within the adjusting frame 21, allowing for fine-tuning of the left and right positions of the fixed frame 28, ensuring alignment of the suction cup array with the wall panel's center of gravity. A fixed frame 28 is fixedly connected to the lower surface of the slider 27, with its upper end fixed to the slider 27, providing a horizontal mounting platform for the auxiliary suction cups 284. An adjustable suction cup array is formed by the moving groove 281, the limiting block 282, and the moving block 283 to accommodate different widths. The wall panel and the fixing frame 28 have two sets of moving grooves 281 on both the left and right ends of their upper surface. These grooves guide the linear displacement of the moving block 283, allowing for continuous adjustment of the lateral position of the auxiliary suction cup 284. Two sets of limiting blocks 282 are fixedly connected to both ends of the fixing frame 28. These limiting blocks restrict the maximum stroke of the moving block 283, preventing it from slipping out of the moving groove 281, and also act as mechanical stops to improve operational safety. The moving block 283 is slidably connected to the inner wall of the moving groove 281, and is slidably embedded within it. The lower end of the moving block 283 is detachably connected to the auxiliary suction cup 284. By changing its position within the groove, the suction cup spacing can be infinitely adjusted, optimizing the suction point layout.An auxiliary suction cup 284 is detachably connected to the bottom of the movable block 283. The auxiliary suction cup 284 has a hollow interior and rounded outer walls. This hollow, rounded-corner structure allows for detachable connection to the movable block 283, directly forming a vacuum seal with the wall panel surface. The rounded outer walls reduce the risk of scratches. The hollow cavity stores instantaneous negative pressure, improving the adsorption response speed.

[0025] Reference Figure 2 - Figure 4 The auxiliary component 3 includes an auxiliary seat 31, which is slidably connected to grooves on the left and right surfaces of the outer wall of the support frame 1. The auxiliary seat 31 is slidably embedded in the grooves on the left and right surfaces of the support frame 1 to support the lifting rod 33 and the positioning plate 34. The lateral position can be adjusted by sliding to adapt to different wall panel widths and working spaces. The left surface of the auxiliary seat 31 is detachably connected to multiple sets of fixing bolts 32. The fixing bolts 32 are used to lock the auxiliary seat 31 in any position in the groove of the support frame 1 to prevent lateral movement during operation. The lower surface of the auxiliary seat 31 is threaded with the lifting rod 33. The length of the lifting rod 33 can be finely adjusted by rotation, thereby changing the height difference between the positioning plate 34 and the support frame 1 to compensate for the wall panel thickness difference. To address uneven ground conditions, a positioning plate 34 is fixedly connected to the lower surface of the lifting rod 33. The positioning plate 34 provides rigid support for the suction cup strip 35 and simultaneously distributes the negative pressure load generated by the suction cup strip 35 to the lifting rod 33, preventing local deformation. The suction cup strip 35 is fixedly connected to the lower surface of the positioning plate 34. The suction cup strip 35 is used to form line contact adsorption with the edge or center of the wall panel, improving the overall adsorption area and stability of the gripper. Two sets of protective pads 36 are detachably connected to both ends of the suction cup strip 35. The protective pads 36 are detachably installed at both ends of the suction cup strip 35 and are made of flexible and wear-resistant material. They are used to buffer the collision between the suction cup strip 35 and the wall panel or external objects when releasing the wall panel, while preventing sharp metal edges from scratching the surface of the wall panel.

[0026] Working principle:

[0027] The entire machine is supported by a frame 1, which is rigidly connected to a load-bearing column 5 via a support base 4 at its upper end. The load-bearing column 5 docks with an external robotic arm or overhead crane, and is responsible for transferring the weight of the entire machine and the load of the wall panels to the handling equipment, and realizing macroscopic movements such as lifting, translation, and rotation. The entire machine's workflow can be divided into four stages: "positioning - adsorption - handling - release".

[0028] The external control system moves the entire machine directly above the wall panel to be transported, at which point the auxiliary component 3 begins operation. The auxiliary seat 31 slides laterally within the grooves on the left and right sides of the support frame 1. After determining the optimal span based on the width of the wall panel, it is locked by multiple sets of fixing bolts 32 to prevent lateral movement during subsequent operations. Subsequently, the lifting rod 33 is rotated, causing it to move up and down relative to the auxiliary seat 31 under the influence of the threaded mechanism. This moves the positioning plate 34 and the suction cup strip 35 fixed to its lower surface to a preset gap with the wall panel surface. The protective pads 36 at both ends of the suction cup strip 35 provide cushioning and anti-scratch protection before contact. At this point, the auxiliary component 3 completes its pre-positioning and provides additional support points to prevent large-sized wall panels from bending and deforming.

[0029] The suction cup assembly 2 enters the active adsorption process. The adjusting frame 21 is fixed to the front end of the lower surface of the support frame 1. The adjusting blocks 22 in the front and rear grooves of the adjusting frame 21 automatically or manually adjust their front and rear positions according to the length of the wall panel, thereby driving the piston column 23 and the telescopic rod 24 to move synchronously, ensuring that the suction cup array is aligned with the longitudinal center of the wall panel. The slider 27 slides laterally on the inner wall of the adjusting frame 21, so that the fixed frame 28 is centered left and right, thereby ensuring that the lateral center of gravity of the suction cup array is consistent with the wall panel. In the moving groove 281 on the upper surface of the fixed frame 28, the moving block 283 slides as needed and the stroke is limited by the limiting block 282, realizing stepless adjustment of the spacing of the auxiliary suction cups 284 to form an optimal adsorption layout.

[0030] When the external vacuum source is activated, the negative pressure is simultaneously distributed to all auxiliary suction cups 284 through the internal air passage of the piston column 23 and the inner cavity of the suction cup holder 26. The telescopic rod 24 forms a flexible buffer under the action of the spring 25: the telescopic rod 24 is compressed the instant the suction cup contacts the wall panel, and the spring 25 stores energy to provide continuous clamping force, avoiding rigid impact; after the vacuum is established, the rebound force of the spring 25 and the negative pressure adsorption force are superimposed, ensuring that the anti-slip textured suction cup fully adheres to the wall panel surface, achieving a reliable seal. The hollow, rounded corner structure of the auxiliary suction cups 284 not only increases the instantaneous air storage volume and improves the response speed, but also reduces the risk of scratches due to the rounded outer wall.

[0031] In vacuum-maintained mode, external handling equipment lifts, moves, or rotates the entire machine along with the wall panel via the load-bearing column 5 and support base 4. During this process, the support frame 1 transfers the load from the suction cup assembly 2 and auxiliary assembly 3 to the load-bearing column 5. The distributed adsorption surface formed by the auxiliary suction cup 284 and the suction cup strip 35 jointly bears the weight of the wall panel, preventing local stress concentration that could lead to cracking or detachment of the wall panel. Upon reaching the target workstation, the vacuum source is shut off, and the pressure difference between the inside and outside of the suction cups disappears. The spring 25 rebounds, and the telescopic rod 24 drives the suction cup frame 26 and auxiliary suction cup 284 to quickly detach from the wall panel surface. The protective pads 36 at both ends of the suction cup strip 35 again act as a buffer, preventing sharp metal edges from colliding with the wall panel. Subsequently, the external handling equipment moves the entire machine back to the standby position, completing one work cycle.
