Description

Technical Field

[0001] This utility model relates to the field of film coating technology, and in particular to a device for turning over flexible film materials. Background Technology

[0002] In industrial production, many products require lamination, such as sheet metal processing, power battery production, and display screen manufacturing. In lamination, the stacked flexible films are first separated one by one, then the flexible films are loaded into the designated position on the lamination equipment. The equipment then covers and adheres the flexible films to the products requiring lamination according to the processing requirements.

[0003] The flexible film used in the lamination process is purchased from the market. The purchased flexible film is in a stacked state, with all layers aligned in the same direction. Currently, the flexible film material is typically picked up using suction cups. When both sides of the product need to be laminated, the flexible film material needs to be fed into the lamination device according to the feeding sequence to ensure either the front or back is fed and placed correctly. However, existing flexible film material feeding devices lack a flipping function. To achieve front and back feeding, at least two feeding stations are required, which is unsuitable for compact processing scenarios. The feeding device has a larger movement range, feeding is slower, and the material is easily misaligned during pickup, severely impacting the processing efficiency and quality of the lamination process.

Detailed Implementation

[0023] like Figures 1 to 3 As shown, in one embodiment of the present invention, the flexible film material flipping device includes a moving mechanism and a gripping end; the gripping end includes: a mounting frame 1, a first flipping suction component 101, and a second flipping suction component 102; the mounting frame 1 is horizontally arranged and connected to the moving mechanism; the moving mechanism is used to realize the vertical lifting and / or horizontal movement of the mounting frame; the first flipping suction component 101 includes: a first driving device 2 and a first suction cup component; the second flipping suction component 102 includes: a second driving device 3 and a second suction cup component; the first suction cup component is disposed on the... The second suction cup is located on the right side of the mounting frame 1. Under the drive of the first driving device 2 and the second driving device 3, both the first and second suction cups can rotate around the rotating axis set in the front-back direction of the mounting frame 1. When the suction cup openings of the first and second suction cups rotate towards the center of the mounting frame 1 and face each other, the suction cup openings of the first and second suction cups are close to both sides of the same adsorption plane, and the first and second suction cups can adsorb and grasp the flexible film material adsorbed by each other.

[0024] The flexible film material flipping device can pick up and feed or pick up and flip up the flexible film material placed in a stacked state according to the feeding needs. The flexible material flipping device has a compact structure, lower requirements for installation and operation space, wider application range, simple and ingenious flipping operation, flexible and precise feeding operation of flexible film material, and accurate and efficient feeding process.

[0025] Preferably, when the suction cup openings of the first and second suction cup components are both flipped towards the center of the mounting frame 1 and facing each other, the first and second suction cup components are horizontally aligned and facing each other; the suction cup openings of the first and second suction cup components are close to both sides of the same vertical adsorption plane. When a flipping operation is required, the right edge of the flexible film material is adsorbed and bent by the first suction cup component, and when in a vertical state, it is horizontally adsorbed by the second suction cup 31; this ensures that the adsorption transition between the first and second suction cups 21 is achieved in the horizontal direction, which is easier to control and more conducive to ensuring accuracy compared to operation in the inclined direction.

[0026] Preferably, when the suction cup openings of the first and second suction cup components are both flipped towards the center of the mounting frame 1 and face each other, the gap between the suction cup openings of the first and second suction cup components and the same vertical adsorption plane is 0-3mm. During the adsorption transition between the first and second suction cup components, the closer the two suction cup openings are, the better. If the distance between the two suction cup openings and the adsorbed flexible film material is too large, the adsorption force and speed of the suction cups on the flexible film material cannot meet the operational requirements, and the flexible film material is prone to falling off during the adsorption transition operation between the two suction cups. Therefore, limiting the distance between the suction cup openings and the adsorbed flexible film material to the above-mentioned range is a preferred distance range, ensuring operational progress and efficiency.

[0027] The first suction cup component includes a first suction cup 21 and a first swing arm component 22; the second suction cup component includes a second suction cup 31 and a second swing arm component 32; a first rotating shaft 4 is provided on the bottom left side of the mounting frame 1 via a bearing component; a second rotating shaft 5 is provided on the bottom right side of the mounting frame 1 via a bearing component, the first rotating shaft 4 and the second rotating shaft 5 are arranged parallel to each other in the front-back direction in the same plane; the upper end of the first swing arm is fixedly connected to the first rotating shaft 4, the lower end of the first swing arm is fixedly connected to the first suction cup 21, and the air source connection port of the first suction cup 21 is connected to the air supply pipe of an external air source driving device; the upper end of the second swing arm is fixedly connected to the second rotating shaft 5, the lower end of the second swing arm is fixedly connected to the second suction cup 31, and the air source connection port of the second suction cup 31 is connected to the air supply pipe of an external air source driving device; the first driving device 2 is drivenly connected to the first rotating shaft 4; the second driving device 3 is drivenly connected to the second rotating shaft 5; so that the first rotating shaft 4 and the second rotating shaft 5 can rotate around their own axes.

[0028] There are many specific implementations of the first driving device 2 and the second driving device 3. For example, the first driving device 2 and the second driving device 3 are rotary motors; the rotary motors are connected to the rotating shaft through a reduction mechanism.

[0029] For example, the first driving device and the second driving device 3 are telescopic driving devices, and the two telescopic driving devices are respectively installed at the front end and the rear end of the mounting frame 1; the telescopic driving end of the telescopic driving device is hinged to the driving arm 6 provided at the end of the flipping shaft at the corresponding position; when the first driving device 2 retracts, the first suction cup 21 can be vertically downward, and when the first driving device 2 extends, the first suction cup 21 can be horizontally to the right; when the second driving device 3 retracts, the second suction cup 31 can be vertically downward, and when the second driving device 3 extends, the second suction cup 31 can be horizontally to the left.

[0030] Specifically, both the first flip-and-suction assembly 101 and the second flip-and-suction assembly 102 further include an air blowing assembly 7; the two air blowing assemblies 7 are respectively fixedly installed on the first swing arm 22 and the second swing arm 32, and the air blowing assemblies 7 are arranged in the front-to-back direction.

[0031] The air blowing assembly 7 is rod-shaped with a hollow air cavity inside. Its side wall has at least one air source interface 71 and an air blowing port 72. The air source interface 71 of the air blowing assembly 7 is connected to the air supply device of an external air blowing device. The air blowing port 72 is always parallel and consistent with the orientation of the suction cup opening of the corresponding suction cup. This makes the structure of the air blowing assembly 7 simple and lightweight, while ensuring that the gas blown out by the air blowing assembly 7 can smoothly enter the gap between the adsorbed flexible film material and other stacked flexible film materials, which facilitates the rapid separation of the flexible film materials.

[0032] Preferably, the mounting frame 1 is further equipped with an ion generator, which causes the gas blown out by the blowing assembly 7 to be an ion wind. This allows for rapid separation of the flexible film material during the adsorption operation, while the ion wind eliminates static electricity between the flexible film materials, further preventing electrostatic interference. This ensures that the flexible film material flipping device can accurately and quickly adsorb one layer of flexible film material each time, avoiding adhesion of the flexible film material during the adsorption and feeding process.

[0033] There are many different implementations of the moving mechanism with the above functions. The moving mechanism can be an existing XZ axis slide rail drive mechanism or an industrial robot. When the mounting bracket 1 is installed on the moving mechanism, the moving mechanism can drive the mounting bracket 1 to move along the X axis and / or rise and fall along the Z axis.

[0034] The XZ-axis slide rail drive mechanism and industrial robot are both existing technologies and can be applied to the flexible film material flipping device of this utility model. They mainly drive the mounting frame 1 and its mounting structure to move along the X-axis and / or rise and fall along the Z-axis as needed. The X-axis corresponds to the left-right direction, and the Z-axis corresponds to the vertical direction.

[0035] The XZ axis slide rail drive mechanism is a commonly used moving mechanism in the prior art, which includes: an X-axis slide rail, a Z-axis slide rail (or a Z-axis telescopic device), a sliding plate, a connecting end plate, a lead screw mechanism, and a drive motor; the X-axis slide rail is horizontally arranged in the left-right direction, the sliding plate is slidably mounted on the X-axis slide rail, the Z-axis slide rail is mounted on the sliding plate, the connecting end plate is slidably mounted on the Z-axis slide rail, and the mounting frame 1 is connected to the connecting end plate; the lead screw mechanism and the drive motor are used to drive the mounting frame 1 and its mounting structure to move along the X-axis and / or Z-axis.

[0036] like Figure 4 As shown, the industrial manipulator is a KUKA robot, which includes a base 81, a drive motor 82, a movable joint 83, and a connecting end 84 connected to the gripping end.

[0037] The working principle of the flexible membrane material flipping device in practical applications is as follows: like Figure 5 As shown, during the adsorption and feeding operation, i.e., when the flexible film material does not need to be flipped over and is directly sucked up and fed to the designated position, the moving mechanism moves the gripping end above the stacked flexible film material. Then, the second suction cup 31 of the second flipping suction assembly 102 adsorbs onto the left edge of the flexible film material. The gripping end slowly lifts the left edge of the flexible film material upwards. At the same time, the first suction cup 21 and the second suction cup 31 both flip towards the center of the mounting frame 1 at a certain angle, tilting downwards, so that the left edge of the flexible film material folds upwards. The air blowing assembly 7 provided with the first flipping suction assembly 101 can blow gas to the bottom of the folded flexible film material, so that the flexible film material can be easily separated from the bottom flexible film material. After the flexible film material is separated from the bottom flexible film material, the moving mechanism drives the gripping end to adsorb the flexible film material and move it to the designated position, and then releases the second suction cup 31, completing the adsorption and feeding operation of the flexible film material.

[0038] like Figure 6 As shown, during the adsorption and flipping feeding operation, that is, when the flexible film material needs to be flipped over first and then sucked up and fed to the designated position, the moving mechanism moves the gripping end to above the stacked flexible film material, and then the first suction cup 21 of the first flipping suction component 101 adsorbs the right edge of the flexible film material. The gripping end slowly lifts the right edge of the flexible film material upward. At the same time, the first suction cup 21 and the second suction cup 31 both flip towards the middle of the mounting frame 1, so that the left edge of the flexible film material is folded upward. The air blowing component 7 provided by the second flipping suction component 102 can blow gas to the bottom of the folded flexible film material, so that the flexible film material can be smoothly separated from the bottom flexible film material. After the flexible film material separates from the bottom flexible film material, the first suction cup 21 and the second suction cup 31 both flip towards each other towards the center of the mounting frame 1 until they stop in a horizontal facing state. At this time, the first suction cup 21 removes its adsorption force while the second suction cup 31 generates an adsorption force. The second suction cup 31 picks up the flexible film material, and the moving mechanism drives the gripping end to move to the left while adsorbing the flexible film material. At the same time, the second suction cup 31 gradually flips to face downwards. The second suction cup 31 picks up the flexible film material and continues to move to the left, thus completing the flipping operation of the flexible film material. Finally, the second suction cup 31 picks up the flexible film material to the designated position, and then releases the second suction cup 31, completing the adsorption and flipping operation of the flexible film material.
