Description

Technical Field

[0001] The utility model belongs to the field of data line production lines, and particularly relates to a film folding machine for automatically folding a data line protection cover. Background Technique

[0002] Data lines are often used in digital products for charging and data transmission. When packaging data lines after manufacturing, first, a rotating mechanism is required to make them into a winding group. The mechanical claw takes away the winding group and transfers it to the next station. At this time, the winding group is in the card slot. Under the push of another air rod, the winding group advances in the card slot and then enters the protection cover, and the protection cover is in a sleeve ring shape. The initial state of the protection cover is a rectangular sheet, and it needs to go through a series of operations such as film folding and film buckling, and then form a ring-shaped packaging film, and finally be placed at the position where the winding group is to pass through.

[0003] In the film folding process, the traditional robotic arm only sucks one film sheet from the material tray and sends it into the bending die each time. Since placing the film sheet requires a relatively large space and can only be far away from the processing area, the robotic arm travels a relatively long distance back and forth each time. After the bending die folds the film, the processing area often waits for the robotic arm to put the film sheet in again. In order to reduce the moving distance of the robotic arm when sucking the film sheet, how to arrange the material tray in a closer position is a problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a film folding machine for automatically folding a data line protection cover that is convenient for the robotic arm to pick up materials.

[0005] To achieve the above object, the utility model provides a film folding machine for automatically folding a data cable protective cover, comprising: a plurality of large film pieces, each large film piece including a back film and a plurality of small film pieces temporarily adhered to the back film, the plurality of small film pieces being evenly distributed. When the large film piece is placed, the back film is located above and the plurality of small film pieces are located below; a feeding mechanism, which includes a tray for supporting the large film piece, a first robotic arm for grasping the large film piece, and a plurality of first vacuum suction cups located at the movable end of the robotic arm. The first robotic arm drives the vacuum suction cups to reciprocate, and the vacuum suction cups adhere to the large film piece to complete the grasping, and then the vacuum suction cups close the negative pressure to release the large film piece; a transfer platform, which includes at least two main support rods, guide rods located on the main support rods, and a push rod located at the head end of the main support rods. The main support rods support the large film piece and its small film pieces, and a plurality of negative pressure holes for temporarily adsorbing the small film pieces are provided on the main support rods. The guide rods are located on the left and right sides of the large film piece to prevent the large film piece and the small film pieces from shifting, and the push rod is used to push the plurality of small film pieces one by one to the film folding station; a discharging mechanism, which includes a tray for supporting the back film, a second robotic arm for transferring the back film and its second vacuum suction cup. When the main support rod adsorbs the small film pieces, the second robotic arm drives the second vacuum suction cup to move above the back film. After the second vacuum suction cup sucks the back film, the back film and the plurality of small film pieces are separated, and at the same time the second vacuum suction cup transfers the back film to the tray and releases it.

[0006] As an improvement of the above solution, both the first robotic arm and the second robotic arm are driven by three-axis linear guide rails, and both the first vacuum suction cup and the second vacuum suction cup have three degrees of freedom.

[0007] As an improvement of the above solution, the discharging mechanism further includes a third robotic arm and its third vacuum suction cup. The third robotic arm is driven by a swing rod, and the third robotic arm drives the third vacuum suction cup to move in an arc. The third vacuum suction cup adheres to the edge of the back film to tear the back film, and after the third vacuum suction cup swings away from the transfer platform, then the second vacuum suction cup transfers the back film to the tray.

[0008] As an improvement of the above solution, an auxiliary support rod is further provided between the two main ones. The movable end of the push rod extends and retracts in the space between the auxiliary support rod and the main support rod and abuts against the side of the small film piece.

[0009] As an improvement of the above solution, the first vacuum suction cup, the second vacuum suction cup and the third vacuum suction cup are all of linear structures and are provided with a plurality of negative pressure holes at intervals.

[0010] As an improvement to the above solution, the film folding machine further includes a film folding mechanism, which includes a fourth robotic arm, a fourth vacuum suction cup for successively picking up the small film pieces, and a clamping arm and a roller for bending the small film pieces.

[0011] The utility model has the following beneficial effects: The film folding machine can load several small film pieces at one time, and then use the push rod to successively push the small film pieces to the position closest to the film folding mechanism (the next working station). On this basis, the small film pieces can either be directly pushed into the processing area of the film folding mechanism or transferred into the processing area of the film folding mechanism by the fourth vacuum suction cup. Each loading is rapid, ensuring that the loading speed is close to the bending speed, thereby improving production efficiency. Description of the Drawings

The first robotic arm 11 drives the vacuum suction cups to reciprocate, and the vacuum suction cups adhere to the large film sheet 51 to complete the grasping, and then the vacuum suction cups close the negative pressure to release the large film sheet 51; a transfer platform, which includes at least two main support rods 61, guide rods 63 located on the main support rods 61, and a push rod 64 located at the head end of the main support rods 61. The main support rods 61 support the large film sheet 51 and its small film sheets 52. A plurality of negative pressure holes for temporarily adsorbing the small film sheets 52 are provided on the main support rods 61. The guide rods 63 are located on the left and right sides of the large film sheet 51 to prevent the large film sheet 51 and the small film sheets 52 from shifting. The push rod 64 is used to push the plurality of small film sheets 52 to the film folding station one by one; a discharging mechanism, which includes a tray for supporting the back film 53, a second robotic arm 21 for transferring the back film 53, and a second vacuum suction cup 22 thereof. When the main support rod adsorbs the small film sheets 52, the second robotic arm 21 drives the second vacuum suction cup 22 to move above the back film 53. After the second vacuum suction cup 22 sucks the back film 53, it separates the back film 53 from the plurality of small film sheets 52, and at the same time, the second vacuum suction cup 22 transfers the back film 53 to the tray and releases it.

The third robotic arm 32 drives the third vacuum suction cup to move in an arc. The third vacuum suction cup fits against the edge of the back film 53 to tear off the back film 53. After the third vacuum suction cup swings away from the transfer platform, the second vacuum suction cup 22 then transfers the back film 53 to the tray. With the above solution, the movement range of the second robotic arm 21 and the second vacuum suction cup 22 is reduced, avoiding interference between adjacent components.

[0022] As an improvement to the above solution, an auxiliary support rod 62 is further provided between the two main ones. The auxiliary support rod 62 is used to support the middle position of the small diaphragm 52.
