Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, and in particular to an aluminum foil core coating device. Background Technology

[0002] The winding process is an important step in aluminum foil production. It involves winding the produced aluminum foil together by rotating a core or roll to facilitate storage and transportation.

[0003] When the winding process begins, the core needs to be pre-treated to increase the adhesion between the aluminum foil and the core. Existing technologies pre-treat the core using three methods: alcohol pre-treatment, tape pre-treatment, and brush pre-treatment.

[0004] Among these methods, alcohol-based priming involves coating with alcohol, but alcohol evaporates quickly, resulting in insufficient adhesion and a tendency to slip and curl. Tape-based priming uses adhesive tape, but the tape has poor elasticity, easily causing wrinkles and curling at the bottom of the container, and materials at the bottom of the container are easily thrown out. Brush-based priming uses a brush to apply adhesive, but the amount of adhesive applied is difficult to control, easily overflowing and contaminating the aluminum foil surface. Furthermore, all three methods require manual operation, resulting in low work efficiency. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model proposes an aluminum foil core coating device to solve the problems of slippage, wrinkling of the roll bottom, material spillage, glue overflow, and low work efficiency in the existing core coating method.

It includes a base plate, two side plates fixed to opposite ends of the base plate and arranged facing each other, a first motor fixed to one side plate away from the other, a lead screw with both ends rotatably connected to the two side plates, a nut sleeved on the lead screw and threadedly connected to it, a guide rod with both ends fixed to the two side plates and parallel to and spaced apart from the lead screw, a moving platform fixed to the nut and spaced apart from the base plate, a second motor fixed to the moving platform away from the base plate, and a rotating shaft connected to the output shaft of the second motor. The system comprises a moving platform, a robotic arm fixed to the rotating platform on the side away from the second motor, a pressure sensor fixed to the end of the robotic arm away from the second motor, and a gripper fixed to the pressure sensor on the side away from the robotic arm. The gripper is used to hold a magic eraser for coating the tube core with formaldehyde-free white latex. The two side plates are perpendicular to the base plate. The output shaft of the first motor is coaxially arranged and fixedly connected to the lead screw. The guide rod and the lead screw pass through the moving platform and are slidably connected to the moving platform. The output shaft of the second motor is perpendicular to the base plate. The robotic arm is driven to move by a third motor, and the gripper is driven to move by a fourth motor.

[0007] Preferably, the magic eraser comprises a plurality of melamine foam blocks stacked and fixed in sequence, and the grippers simultaneously hold the same end of three of the melamine foam blocks.

[0008] Preferably, the aluminum foil core coating device further includes a first housing fixed to one of the side plates away from the other side plate; the first motor is fixed inside the first housing, and the output shaft of the first motor passes through the first housing and is fixedly connected to the lead screw.

[0009] Preferably, the guide rods include two rods located on opposite sides of the lead screw, and the two guide rods are equally spaced from the lead screw; the moving platform is respectively sleeved on the two guide rods.

[0013] Preferably, the aluminum foil core coating device further includes a formaldehyde-free white latex storage tank disposed on the same side as the base plate and spaced apart from the base plate.

[0014] Compared with existing technologies, the aluminum foil core coating device of this invention uses a first motor, a second motor, a third motor, and a fourth motor to drive related components, thereby achieving automated core coating, improving coating efficiency, and reducing costs.

[0022] This utility model embodiment provides an aluminum foil core adhesive coating device 100, combined with... Figure 1As shown, it includes a base plate 1, two side plates 2 fixed to opposite ends of the base plate 1 and arranged facing each other, a first motor 3 fixed to one side plate 2 away from the other side plate 2, a lead screw 4 with both ends rotatably connected to the two side plates 2, a nut 5 sleeved on the lead screw 4 and threadedly connected to the lead screw 4, a guide rod 6 with both ends fixed to the two side plates 2 and parallel to and spaced apart from the lead screw 4, a moving platform 7 fixed to the nut 5 and spaced apart from the base plate 1, a second motor fixed to the moving platform 7 away from the base plate 1, a rotating platform 9 connected to the output shaft of the second motor, a robotic arm 10 fixed to the rotating platform 9 away from the second motor, a pressure sensor 11 fixed to the end of the robotic arm 10 away from the second motor, and a gripper 12 fixed to the pressure sensor 11 away from the robotic arm 10. The gripper 12 is used to hold a magic eraser 13 for coating the tube core with formaldehyde-free white latex.

[0023] Among them, the aluminum foil core coating device 100 is used to coat the core 19 of the wound aluminum foil with formaldehyde-free white latex, and the concentration of formaldehyde-free white latex is preferably 10-20%; the two side plates 2 are respectively perpendicular to the plane of the base plate 1; the output shaft of the first motor 3 is coaxially arranged and fixedly connected with the lead screw 4; the guide rod 6 and the lead screw 4 pass through the moving platform 7 respectively and form a sliding connection with the moving platform 7 respectively; the output shaft of the second motor is arranged perpendicular to the base plate 1; the robotic arm 10 is driven to move by the third motor 14; and the gripper 12 is driven to move by the fourth motor 15.

[0024] The base 101 and side plates 2 are used to fix the remaining components; the first motor 3 is used to drive the lead screw 4 to rotate, thereby causing the nut 5 to move along the axial direction of the lead screw 4; the lead screw 4 and the nut 5 form a rolling lead screw mechanism, and the length of the lead screw 4 between the two side plates 2 is at least equal to the length of the core 19, so as to ensure that the magic eraser 13 can completely coat the core 19; the guide rod 6 is provided to prevent the moving platform 7 from rotating when the nut 5 rotates along the thread of the lead screw 4; the second motor is provided to drive the rotating platform 9 to rotate. The robotic arm 10 is rotated to move the magic eraser 13 to a designated position to adsorb formaldehyde-free white glue. The robotic arm 10 is driven by multiple third motors 14 to perform actions such as contraction, extension, and pressing of its arm joints, which in turn drive the gripper 12 and the magic eraser 13 to move. The pressure sensor 11 is used to detect the pressure between the magic eraser 13 and the core tube 19. The gripper 12 is driven by a fourth motor 15 to grip the magic eraser 13. The magic eraser 13 is used to adsorb formaldehyde-free white glue and apply the formaldehyde-free white glue to the core tube 19.

[0025] The robotic arm 10 and gripper 12 are driven by a motor, which ensures that the pressure between the magic eraser 13 and the core tube 19 is constant, thereby ensuring that the coated adhesive layer is uniform and reducing the risk of injury to personnel due to the degree of movement.

[0026] The magic eraser 13 comprises multiple melamine foam blocks stacked and fixed in sequence, with the grippers 12 simultaneously holding the same end of three melamine foam blocks. This allows the magic eraser 13 to better absorb formaldehyde-free white glue and coat it onto the core 19.

[0027] The robotic arm 10 includes a base 101 and a robotic arm body 102 fixed to the base 101. The base 101 is fixed to the rotating platform 9 by multiple bolts. Part of the third motor is fixed to the base 101 and its output shaft is hinged to the robotic arm body 102. The remaining third motors are fixed between two adjacent arm segments to drive the arm segment movement. This design allows the robotic arm 10 to be better fixed to the rotating platform 9.

[0028] In this embodiment, there are two guide rods 6, located on opposite sides of the lead screw 4, with the two guide rods 6 spaced equidistant from the lead screw 4; the moving platform 7 is sleeved on the two guide rods 6. This design better guides the moving platform 7, preventing it from loosening or shifting when moving along the axial direction of the lead screw 4.

[0029] The aluminum foil core coating device 100 also includes a first housing 31 fixed to one of the side plates 2 away from the other side plate 2; a first motor 3 is fixed inside the first housing 31, and the output shaft of the first motor 3 passes through the first housing 31 and is fixedly connected to the lead screw 4. This design allows the first motor 3 to be better protected by the first housing 31, thereby achieving a dustproof effect, and also allows the first motor 3 to be better fixed to the side plate 2.

[0030] The aluminum foil core coating device 100 also includes a second housing 8 fixed to the side of the moving platform 7 away from the base plate 1; the second motor is fixed inside the second housing 8, and the output shaft of the second motor passes through the second housing 8 and is fixedly connected to the rotating platform 9. This design allows the second motor to be better protected by the second housing 8, thereby achieving a dustproof effect, and also allows the second motor to be better fixed to the moving platform 7.

[0031] The aluminum foil core coating device 100 also includes a first fixing plate 16 fixed to the end of the robotic arm body 102 away from the base 101 and a second fixing plate 17 fixed to the side of the pressure sensor 11 away from the robotic arm body 102. The pressure sensor 11 is fixed to the side of the first fixing plate 16 away from the robotic arm body 102, and the gripper 12 is fixed to the side of the second fixing plate 17 away from the pressure sensor 11. This design allows the pressure sensor 11 to be better fixed to the robotic arm 10, and also allows the gripper 12 to be better fixed to the pressure sensor 11.

[0032] The aluminum foil core coating device 100 also includes a formaldehyde-free white latex storage tank disposed on the same side as the base plate 1 and spaced apart from the base plate 1. This design allows the magic eraser 13 to rotate more effectively to the designated position and absorb the formaldehyde-free white latex.

[0033] In this embodiment, when using the aluminum foil core coating device 100, the first step is to move it to the side of the core 19 in a fixed position and set the operating speed of the core 19 to 50 m / min. The second step is to drive the rotating platform 9 to rotate via the second motor, so that the robotic arm 10 rotates to above the formaldehyde-free white latex storage tank. Then, the fourth motor 15 drives the gripper 12 to lower the magic eraser 13, so that the magic eraser 13 is immersed in the formaldehyde-free white latex liquid for 5-10 seconds to ensure that it fully absorbs the formaldehyde-free white latex. The third step is to drive the robotic arm 10 to move to the position of the magic eraser 13 via the third motor 14, and then drive the gripper 12 via the fourth motor 15 to pick up the magic eraser 13. After that, the third motor 14 drives the robotic arm 10 to move the magic eraser 13 to the designated position. The second motor drives the rotating platform 9 to rotate, causing the magic eraser 13 to rotate above the core 19. The fourth step involves the third motor 14 driving the robotic arm 10 to move the magic eraser 13 to contact the core 19 and press it down until the pressure sensor 11 detects a pressure value of 0.06-0.09 N, at which point the third motor 14 stops. The fifth step involves the first motor 3 driving the lead screw 4 to rotate, causing the moving platform 7 to move at a speed of 0.1-0.2 m / s via the nut. This, in turn, moves the magic eraser 13 via the robotic arm 10, coating the surface of the core 19 2-3 ​​times to ensure a uniform adhesive layer of 10-30 μm thickness is formed. The adhesive layer needs to be semi-cured before the aluminum foil can be wound. By setting the operating speed of the core 19 and the moving speed of the moving platform 7, it can be ensured that the surface of the core 19 is fully covered by the formaldehyde-free white emulsion. Verification has shown that when the pressure is 0.2-0.3 N / cm... 2 This ensures that the 100*30mm surface of the Magic Eraser 13 can completely fit the core 19.

[0034] The first motor 3, the second motor, the third motor 14, and the fourth motor 15 are all driven by an external controller 18. The detection data of the pressure sensor 11 is transmitted to the external controller 18, which can control the operation of the first motor 3, the second motor, the third motor 14, and the fourth motor 15. Of course, the external controller 18 can also control the operation of the first motor 3, the second motor, the third motor 14, and the fourth motor 15 according to a set program.

[0035] Compared with existing technologies, the aluminum foil core coating device 100 in this embodiment, driven by a first motor 3, a second motor, a third motor 14, and a fourth motor 15, enables automated coating of the core 19, improving coating efficiency and reducing costs. Using formaldehyde-free white latex as a base coat prevents slippage due to its high viscosity, while also avoiding wrinkling at the bottom of the roll and material spillage from the bottom of the container. The use of a magic eraser 13 as a coating carrier allows for precise control of the adhesive through its pores and elastic deformation properties, preventing overflow. Specifically, the slippage rate can be reduced to below 0.5%, material spillage from the bottom of the container is close to zero, adhesive layer thickness uniformity is improved by 40%, and there is no overflow pollution, reducing production costs by 15-20%.

Those skilled in the art should understand that any modifications or equivalent substitutions made to the present invention without departing from its spirit and scope should be covered within the scope of the present invention.

Additionally, unless specifically stated otherwise, all or part of any embodiment may be used in conjunction with all or part of any other embodiment.
