Description

Technical Field

[0001] This application relates to the field of thin film adsorption, and more particularly to a thin film adsorption device. Background Technology

[0002] In the operation of an automated packaging line, the front end needs to handle crushing, screening, and packaging before being boxed and stacked. During the boxing and stacking process, a layer of plastic film is often placed inside the box to separate each layer of bags; generally, a new layer of film is needed for each additional layer of material. The plastic film currently used in the workshop is soft EPE foam.

[0049] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0050] This utility model provides a thin film absorption device. Please refer to [link / reference]. Figures 1-5 The film suction device includes a moving unit, a lifting unit, and a suction unit.

[0051] Specifically,

[0052] The moving unit includes a guide rail assembly, a moving plate 12, and a first drive assembly. The moving plate 12 is driven to reciprocate along the extension direction of the guide rail assembly through the cooperation between the first drive assembly and the guide rail assembly.

[0053] The guide rail assembly comprises a first guide plate 10a, a second guide plate 10b, and a connecting plate 11. The connecting plate 11 connects the first guide plate 10a and the second guide plate 10b, thereby achieving the positioning arrangement between the first guide plate 10a and the second guide plate 10b. A first slider 14a and a second slider 14b are respectively provided on the facing surfaces of the first guide plate 10a and the second slider 14b, which are arranged parallel to each other, and the extension direction of the two sliders is consistent with the extension direction of their respective guide plates. A rack 13 is arranged along the extension direction of the first guide plate 10a at the surface where the first slider 14a is located.

[0054] The movable plate 12 has a first groove on one side that matches the first sliding block 14a, and a first groove on the other side that matches the second sliding block 14b. The movable plate 12 is positioned between the two guide plates, and the two sliding blocks are slidably connected within their respective grooves, thereby enabling the movable plate 12 to slide in the extension direction of the guide rail assembly. Two slide rails 120 are provided at the bottom of the movable plate, and the inner wall of each slide rail 120 has a second groove aligned with its extension direction.

[0055] Preferably, the guide rail assembly has at least two connecting plates 11, and the two connecting plates 11 are respectively arranged at both ends of the guide plate, with each connecting plate 11 connected between the first guide plate 10a and the second guide plate 10b. One guide rail assembly is connected to another guide rail assembly through the connecting plates 11, thereby lengthening the original guide rail assembly and enabling the separation of the pearl cotton taking and placing areas.

[0056] The first drive assembly includes a first motor 20, a mounting box 22, and a gear 21. One end of the first motor 20 passes through the movable plate 12 and is fitted with a matching gear 21 that meshes with the rack 13, so that the gear 21 and the rack 13 mesh with each other. When the first motor 20 is started to drive the gear 21 to rotate, the interaction between the teeth drives the movable plate 12 to move back and forth along the extension direction of the rack. The other end of the first motor 20 is mounted to the bottom end of the movable plate through the mounting box 22.

[0057] The lifting unit includes a scissor lift 31 and a second drive assembly 32. A first end 310a of the top of the scissor lift is located between two slide rails 120 and fixed to the bottom of a movable plate. The second end 310b of the top of the scissor lift has first sliding protrusions on both sides of its side walls that match second sliding grooves, allowing the second end 310b of the top of the scissor lift to slide slidably connect to the slide rails 120. The bottom of the scissor lift has a third end and a fourth end. The second drive assembly 32 includes a second motor 320 and a screw 321. The second motor 320 is mounted on one side of the movable plate. One end of the screw 321 is mounted to the movable end of the second motor 320, and the other end is threaded through and connected to the second end 310b of the top of the scissor lift, extending towards the first end 310a of the top of the scissor lift.

[0058] The suction unit includes a fixed plate 40 and several suction cups. The top of the fixed plate has a positioning groove 400, the extension direction of which is parallel to the extension direction of the slide rail 120. The inner walls of the two grooves of the positioning groove 400 each have a third sliding groove 401 aligned with its extension direction. The third end 310c of the bottom of the scissor lift is fixed to the fixed plate 40. The two side walls of the fourth end 310d of the bottom of the scissor lift are each provided with a second sliding protrusion 311 that matches the third sliding groove 401, allowing the fourth end 310d of the bottom of the scissor lift to slide slidably connected to the positioning groove 400.

[0059] Based on this, when the second motor 320 starts, it drives the second end 310b at the top of the scissor lift to slide relative to the slide rail 120, thereby causing the fourth end 310d at the bottom of the scissor lift to slide relative to the fixed plate 40, thereby enabling the scissor lift 31 to expand or retract, and thus realizing the lowering or raising of the fixed plate 40.

[0060] Several suction cups are installed on the fixing plate 40. One end of each suction cup 41 protrudes from the top of the fixing plate and is connected to a vacuum generator via a vacuum tube 42. The other end of each suction cup 41 extends to the bottom of the fixing plate 40 to adsorb pearl cotton. In addition, the vacuum tube 42 is equipped with an adjusting valve 43. The other end of the suction cup is provided with a flared part 410. Preferably, the multiple suction cups 41 are evenly spaced along the circumference of the fixing plate 40.

[0061] Based on this, the first driving component enables the moving plate 12 to move and adjust in the extension direction of the guide rail assembly, thereby enabling the suction cup 41 to adjust its position along the extension direction of the guide rail assembly. The lifting unit also enables the vertical position adjustment of the suction cup 41. In summary, the position of the suction cup 41 is aligned with the pearl cotton under the adjustment in the above two directions.

[0062] Furthermore, to ensure a more uniform adsorption force of the suction cups 41 on the pearl cotton, the suction unit also includes a pressure control component. This pressure control component has a pressure sensor 45 and a control processor 44. The pressure sensor 45 is electrically connected to the vacuum generator and the control processor 44. The pressure sensor 45 is installed at the connection between the suction cup 41 and the vacuum tube 42, matching the suction cup 41, so that the adsorption force of each suction cup 41 can be independently monitored by the corresponding pressure sensor 45. The control processor 44 is installed on the outer wall of the vacuum tube 42 near the pressure sensor 45 and is connected to the regulating valve 43. When the suction cup 41 adsorbs the pearl cotton, the pressure sensor 45 monitors the adsorption force of the suction cup 41 and transmits the signal to the control processor 44. The control processor 44 compares the corresponding pressure signal with its set pressure range and controls the regulating valve 43 to keep the adsorption pressure of each suction cup 41 within the set pressure range.

[0063] Based on the above embodiments, the working principle of this application is as follows:

[0064] Start the first motor 20 to drive the gear 21 to rotate. By means of the interaction between the teeth, the moving plate 12 moves along the extension direction of the rack so that the suction cup 41 is above the pearl cotton. Then turn off the first motor 20. Then start the second motor 320 to make the suction cup 41 descend and continuously approach the pearl cotton. Start the vacuum generator and the suction cup 41 picks up the pearl cotton.

[0065] Once the suction cup 41 has absorbed the pearl cotton, start the first motor 20 to move the moving plate 12 along the extension direction of the rack to the pearl cotton placement location, and turn off the vacuum generator so that the pearl cotton is placed on the layer material.

[0066] Based on the above embodiments, the advantages of this application are:

[0067] The first drive component drives the suction cup 41 to adjust its position along the extension direction of the guide rail component, and the lifting unit adjusts the vertical position of the suction cup 41. This allows the suction cup 41 to be accurately aligned with the pearl cotton for easy suction, improving film removal efficiency. Furthermore, by providing a flared part 410 to increase the contact area between the suction cup 41 and the pearl cotton, the adhesion force of the suction cup 41 on the film is more evenly distributed. Moreover, the pressure control component controls the adhesion force of each suction cup 41 within a set range, ensuring that the pearl cotton is subjected to uniform force when being suctioned, further reducing the breakage rate of the pearl cotton during handling.
