Description

Technical Field

[0001] The present application relates to the technical field of acrylic sheets, and in particular to a grabbing and loading device for acrylic sheets. Background Art

[0002] Acrylic, also known as specially treated organic glass, is a replacement product for organic glass. Light boxes made of acrylic have the characteristics of good light transmittance, pure color, rich color, beautiful and smooth appearance, taking into account both day and night effects, long service life, and no impact on use. They are widely used in instrument parts, automobile lights, optical lenses, transparent pipes, etc.

[0003] When processing acrylic sheets, they need to be grabbed and loaded. Currently, a suction cup rack is usually set up, which is lowered to allow the suction cup to adsorb the acrylic sheet. Subsequently, the suction cup rack moves horizontally until it reaches the top of the transport vehicle. The suction cup releases the acrylic sheet and places it on the trolley, thereby transporting the acrylic sheet to the designated processing position through the trolley.

[0004] However, the acrylic sheets placed on the trolley are arranged in a disorderly manner, and need to be manually sorted to place them in a square shape, which is time-consuming and labor-intensive, and the efficiency of acrylic sheet loading is low. Summary of the Invention

[0005] In order to improve the feeding efficiency of acrylic sheets, the present application provides a grabbing and feeding device for acrylic sheets.

[0006] The present application provides a grabbing and loading device for acrylic panels, which adopts the following technical solutions:

[0007] A grabbing and loading device for acrylic plates, comprising:

[0008] The frame is slidably connected to a movable base, and a suction cup is provided at the bottom of the movable base;

[0009] A moving assembly, used for driving the moving seat to slide horizontally;

[0010] The lifting component is used to drive the suction cup to move up and down so that the suction cup can absorb the plate;

[0011] The mobile vehicle has a material receiving seat placed on the top, a positioning plate connected to the top of the material receiving seat, and clamping pieces symmetrically arranged at both ends of the positioning plate. The clamping pieces slide on the material receiving seat, and the clamping pieces are rotatably connected to the rotating roller;

[0012] The square assembly is used to drive the clamping member to move so that the rotating roller clamps the plate, and to drive the rotating roller to rotate so that the plate fits the positioning plate.

[0013] By adopting the above technical solution, the solution uses the coordination of the frame and the movable base, combined with the suction cup to stably adsorb the acrylic sheet, and uses the movable component to achieve precise horizontal transportation, while the height position of the suction cup is adjusted by the lifting component. When the acrylic sheet is placed on the material receiving base, the square assembly drives the clamping part and the rotating roller on it to move, not only firmly clamping the acrylic sheet, but also making the acrylic sheet fit tightly against the positioning plate through the rotation of the rotating roller, thereby significantly improving the accuracy and stability of the acrylic sheet placement, greatly reducing the need for manual intervention, greatly improving production efficiency and reducing the burden on workers.

[0014] Optionally, a mobile frame is provided at the bottom of the mobile seat, and the suction cup is connected to the bottom of the mobile frame. There are multiple suction cups, and they are evenly distributed along the edge of the mobile frame. A fixed column is connected to the middle position of the mobile frame, and the fixed column is slidably connected to the mobile seat. The lifting assembly is used to drive the fixed column to slide on the mobile seat to lift and lower the suction cup.

[0015] By adopting this technical solution, the suction cups are evenly distributed across multiple points, fully covering the acrylic sheet surface. This improves suction stability and reduces the possibility of sheet drop due to uneven force. Furthermore, the sliding coordination between the fixed column and the movable base allows the lifting assembly to precisely control the suction cups' movement, enabling safe and reliable gripping of acrylic sheets of varying thicknesses.

[0017] By adopting the above technical solution, the lifting drive member is connected to the first gear, and the design of the first gear meshing with the first rack can smoothly and accurately drive the fixed column to move up and down, thereby realizing the lifting and lowering action of the suction cup, which not only improves the stability and accuracy of the suction cup's adsorption process on the acrylic plate, but also ensures the reliability of the entire grasping and loading device during operation.

[0018] Optionally, the moving component includes a moving drive, a transmission screw and a guide rod, the moving drive is connected to the frame, the output end of the moving drive is connected to the transmission screw, the end of the transmission screw away from the moving drive is rotatably connected to the frame, both ends of the guide rod are fixedly connected to the frame, the length direction of the guide rod is parallel to the length direction of the transmission screw, the moving seat is threadedly connected to the transmission screw, and the moving seat is slidingly connected to the guide rod.

[0019] By adopting the above technical solution, the mobile driving member drives the transmission screw to rotate, and the movable base moves stably along the direction of the transmission screw with the help of threaded transmission. At the same time, the guide rod plays an auxiliary supporting and guiding role, ensuring that the movable base moves smoothly without deviation, improving the reliability of the device operation, and reducing the possibility of acrylic plate grabbing and loading errors caused by unstable movement, thereby improving overall work efficiency.

[0020] Optionally, a support table is provided at the bottom of the rack, the support table is located at the bottom of the suction cup, and a plurality of limiting members are connected to the top of the support table, and the limiting members are evenly distributed along the edge of the support table.

[0021] By adopting this technical solution, the tray table provides a stable support platform for the suction cups when grasping the acrylic sheet, reducing the possibility of suction deviation caused by operating directly on the ground or other unstable surfaces. Furthermore, multiple stoppers evenly distributed along the edge of the tray table effectively limit the positional deviation of the acrylic sheet, providing preliminary positioning of the acrylic sheet before the suction cups adhere, thereby improving the accuracy and efficiency of subsequent grasping and loading.

[0022] Optionally, the material receiving seat includes a base frame, a sliding frame and a fixing member. The base frame is placed on the top of the mobile vehicle, the top of the base frame is slidingly connected to the bottom of the sliding frame, and the fixing member is used to fix the position of the base frame and the sliding frame.

[0023] By adopting the above technical solution, the base frame and the sliding frame are connected by sliding, and the load-bearing position can be flexibly adjusted to adapt to plates of different sizes or placement requirements.

[0024] Optionally, the base frame includes a bottom frame and a connecting rod. The bottom frame is placed on the top of the mobile vehicle. The bottom frame is connected to the connecting rod. The bottom frame is symmetrically arranged at both ends of the connecting rod. The connecting rod is equidistantly distributed along the length direction of the bottom frame.

[0025] By adopting the above technical solution, the pressure on the acrylic sheet can be evenly distributed, reducing the possibility of deformation or damage of the sheet due to uneven force, thereby improving the safety and reliability of the acrylic sheet during the grabbing and loading process.

[0026] Optionally, the bottom of the material receiving seat is connected to a placing seat, the top of the mobile car is connected to a fixed seat, the fixed seat is rotatably connected to a bidirectional screw rod, and the fixed seats are symmetrically arranged at both ends of the bidirectional screw rod, one of the fixed seats is connected to a bidirectional driving member, the output end of the bidirectional driving member is connected to the bidirectional screw rod, and both ends of the bidirectional screw rod are threadedly connected to positioning blocks.

[0027] By adopting the above technical solution, a bidirectional driving member is used to drive the bidirectional screw to rotate, so that the positioning blocks threadedly connected at both ends thereof move synchronously toward or oppositely, thereby completing the precise positioning of the material receiving seat on the horizontal plane.

[0028] Optionally, oblique grooves are symmetrically provided on both end sides of the placement seat in an eight-shaped shape, and the opposite sides of the two positioning blocks are inclined and match the inclined groove walls of the oblique grooves.

[0029] By adopting the above technical solution, when the positioning block moves under the drive of the bidirectional screw, the placement seat can be accurately positioned through the cooperation of the inclined surface, thereby further improving the accuracy of the placement of the acrylic plate, reducing the need for sorting due to position deviation, and ultimately improving the loading efficiency and degree of automation.

[0031] By adopting this technical solution, the central cylinder in the square assembly rotates under the action of the drive component, driving the threaded rods with oppositely arranged threads to move synchronously, thereby causing the movable plate to slide in the opposite direction, thereby adjusting the position of the clamping member to accommodate acrylic sheets of different sizes. Simultaneously, the coordination of the second gear and the second rack enables the rotating roller to rotate flexibly and apply pressure to the acrylic sheet, ensuring its close fit to the surface of the positioning plate. Furthermore, the arrangement of the first, second, and third springs ensures that when the sheet needs to be released, the rotating roller first retracts and then rotates. This reduces the possibility that the clamping member's rearward movement will drive the rotating roller's rotation, causing the sheet's arrangement position to shift. This significantly improves the placement accuracy of the acrylic sheet, reduces manual intervention, and increases production efficiency.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. This solution utilizes a frame and a mobile base, combined with suction cups to stably hold acrylic sheets. The mobile assembly enables precise horizontal transport, while the height of the suction cups is adjusted by a lifting assembly. When the acrylic sheet is placed on the receiving base, the square assembly drives the clamping parts and their rotating rollers, not only firmly holding the acrylic sheet but also tightly fitting it to the positioning plate through the rotation of the rollers. This significantly improves the accuracy and stability of acrylic sheet placement, greatly reducing the need for manual intervention, significantly increasing production efficiency, and alleviating the burden on workers.

[0034] 2. When the positioning block moves under the drive of the bidirectional screw, it can achieve precise positioning of the placement seat through the cooperation of the inclined surface, thereby further improving the accuracy of the placement of the acrylic sheet, reducing the need for sorting due to position deviation, and ultimately improving the loading efficiency and degree of automation;

[0035] 3. The central cylinder in the squaring assembly rotates under the action of a drive component, driving the threaded rods with opposite threads to move synchronously, causing the movable plate to slide in the opposite direction, thereby adjusting the position of the clamp to accommodate acrylic sheets of varying sizes. Simultaneously, the coordination of the second gear and the second rack enables the rotating roller to rotate flexibly and apply pressure to the acrylic sheet, ensuring a close fit against the surface of the positioning plate. Furthermore, the arrangement of the first, second, and third springs ensures that when the sheet needs to be released, the rotating roller first retracts before rotating. This reduces the possibility of the clamp's rearward movement driving the rotating roller and causing the sheet's arrangement position to shift, significantly improving the placement accuracy of the acrylic sheet, reducing manual intervention, and increasing production efficiency.

The rotation of the two threaded rods 53 drives the two pushing blocks 552 to move toward each other. The pushing blocks 552 drive the clamping parts 44 to slide along the clamping groove 421 through the adjusting part 58, so that the two symmetrically arranged clamping parts 44 move relative to each other, and then drive the rotating roller 45 to clamp the plate. When the clamping parts 44 move, the second spring 57 contracts, causing the second rack 561 to slide stably, and the second rack 561 engages with the second gear 56, thereby driving the second gear 56 to rotate. The rotation of the second gear 56 drives the rotating roller 45 to rotate. The rotating roller 45 rotates and drives the plate toward the direction of the positioning plate 43, so that the plate is attached to the positioning plate 43, and the plate is tidied. There is no need to manually organize the plates, which reduces time and improves efficiency.

[0063] At the same time, refer to Figure 8 The adjusting rod 555 is pushed downward by the adjusting rod 553, and the adjusting rod 555 drives the pushing block 552 to slide through the hinge rod 553, so that the pushing block 552 is inserted between the giving block 551 and the sliding block 554, so that the movable plate 51 moves away from the plate, thereby moving the rotating roller 45 away from the plate, so that the rotating roller 45 retreats first and then rotates, reducing the possibility of the plate arrangement position being offset due to the rotation of the rotating roller 45 when the clamping member 44 retreats, significantly improving the placement accuracy of the acrylic plate, reducing manual participation, and improving production efficiency.

[0064] The implementation principle of the grabbing and loading device for acrylic plates in the embodiment of the present application is as follows: when the acrylic plate is grabbed and loaded, the moving driving member 21 drives the transmission screw 22 to rotate, so that the moving seat 11 moves to the top of the plate, and the lifting driving member 31 is started. The lifting driving member 31 drives the first gear 32 to rotate, and the first gear 32 is engaged with the first rack 33, so that the fixed column 16 is lowered and moved toward the plate, so that the suction cup 12 is attached to the plate, and the suction cup 12 adsorbs the plate. Subsequently, the lifting driving member 31 drives the fixed column 16 to rise, and the suction cup 12 adsorbs the plate. 2 drives the plate to rise, starts the moving drive member 21, and the moving drive member 21 drives the moving seat 11 to move horizontally, so that the plate moves to the top of the sliding frame 42. The lifting drive member 31 drives the fixed column 16 to descend, releases the plate, and makes the plate fall to the top of the sliding frame 42. The driving member 521 is started, and the driving member 521 drives the central cylinder 52 to rotate. The rotation of the central cylinder 52 drives the two threaded rods 53 to rotate, so that the two clamping members 44 move relative to each other, thereby causing the rotating roller 45 to clamp the plate. At the same time, through the movement of the clamping member 44, the second rack 561 The second rack 561 slides and drives the second gear 56 to rotate, thereby driving the rotating roller 45 to rotate, and then the rotating roller 45 moves and rotates at the same time, so that the plate is fitted to the positioning plate 43 for positioning and regularization, without manual processing, saving time. After the plate is regularized, the pushing member 54 is continued to be driven to move. At this time, the rotating roller 45 is clamped on the plate, and it is not easy to push the clamping member 44. Therefore, when the pushing member 54 pushes the adjusting member 58, the pushing member 54 moves down through the adjusting member 58, so that the adjusting member 58 and the clamping member 44 are aligned. A gap appears between them, and the pushing member 54 pushes the adjusting rod 555 through the gap. The adjusting rod 555 drives the pushing block 552 to slide through the hinged rod 553, so that the pushing block 552 is inserted between the giving block 551 and the sliding block 554, so that the movable plate 51 moves away from the plate, thereby making the rotating roller 45 away from the plate, so that the rotating roller 45 retreats first and then rotates, reducing the possibility of the plate arrangement position being offset due to the rotation of the rotating roller 45 when the clamping member 44 retreats, thereby significantly improving the placement accuracy of the acrylic plate, reducing manual participation, and improving production efficiency.

[0065] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and do not limit the scope of protection of the present application in turn. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
