Description

Technical Field

[0001] This utility model relates to an automated layered transfer production line for contact lens mold trays. Background Technology

[0002] The settling process in the production of contact lens molds usually requires placing the mold in a specific environment for 48 hours to ensure the stability of the liquid in the mold and to ensure the molding effect.

[0003] The existing settling process mostly relies on manual transfer. Manual transfer is not only inefficient, but also requires a lot of manual operation, resulting in high labor costs in the production process and failing to fully realize the continuity of the production line. In addition, the existing settling process occupies a large area. Since manual transfer requires setting up multiple storage areas and paths to place the molds in designated locations, the space utilization rate of the production workshop is low, and efficient space management cannot be achieved.

[0004] Therefore, there is an urgent need for a transfer assembly line system that can improve transfer efficiency while reducing the floor space required for the production line. Utility Model Content

Through a vertically arranged multi-layer transfer line structure, combined with a transfer unit, it can automatically realize the multi-layer placement of mold trays, saving space and manpower. This utility model achieves its purpose as follows:

[0006] This utility model proposes an automated layered transfer production line for contact lens mold trays, characterized by comprising a conveying device. One side of the conveying device is provided with a first transfer section and a lifting section, the lifting section being connected to the first transfer section. The lifting section is movable vertically along one side of the conveying device. The first transfer section, after moving with the lifting section, corresponds to various height positions of the conveying device. The other side of the conveying device is provided with a second transfer section and a lifting section, the lifting section being connected to the second transfer section. The lifting section is movable vertically along one side of the conveying device. The second transfer section, after moving with the lifting section, corresponds to various height positions of the conveying device. The conveying device includes at least five conveyor belts arranged vertically, the first transfer section including a conveyor belt, and the second transfer section including a conveyor belt.

[0007] Furthermore, the first transfer unit has a feeding section on one side, and the second transfer unit has a discharging section on one side, making it more convenient to feed and discharge materials.

[0009] Furthermore, the conveying device also includes a support frame, which is fixed to the conveyor belt to increase the robustness of the conveying device.

[0010] Furthermore, the lifting unit includes a lifting frame, a lifting chain, and a motor. The motor is located on the upper part of the lifting frame, and one end of the lifting chain is connected to the motor. This structure further increases the lifting efficiency of the lifting unit, and the structure is simple and easy to install.

[0011] Furthermore, it also includes a control unit, which is electrically connected to the discharge unit and the feed unit, the first transfer unit and the second transfer unit, the conveyor belt, and the motor, thereby increasing the control effect.

These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0016] Please refer to Figure 1This utility model proposes an automated multi-layer transfer line for contact lens mold trays. Its features include a conveying device 3, with a first transfer section 10 and a lifting section 5 on one side of the conveying device 3. The lifting section 5 is connected to the first transfer section 10 and can move vertically along one side of the conveying device 3. The first transfer section 10 moves with the lifting section 5 and corresponds to various height positions of the conveying device 3. A second transfer section 7 and a lifting section 5 are provided on the other side of the conveying device 3. The lifting section 5 is connected to the second transfer section 7 and can move vertically along one side of the conveying device 3. The second transfer section 7 moves with the lifting section 5 and corresponds to various height positions of the conveying device 3. The conveying device 3 includes at least five vertically arranged conveyor belts 9. The first transfer section 10 includes conveyor belts 9, and the second transfer section 7 includes conveyor belts 9. Through this vertically arranged multi-layer conveyor line structure, in conjunction with the transfer sections, multi-layer placement of mold trays can be automatically achieved, saving space and manpower.

[0017] In one possible application scenario, this device is used for the transfer and settling process of contact lens trays. First, the trays are transferred to the first transfer unit 10 via a transfer method. The first transfer unit 10 first transfers the trays to the bottom conveyor belt 9 of the conveying device 3 via the conveyor belt 9. After the trays have moved, the conveyor belt 9 moves to the left to make room for the next tray. Trays are placed in sequence until the bottom conveyor belt 9 of the conveying device 3 is full. Then, the first transfer unit 10 aligns with the second-to-last conveyor belt 9 of the conveying device 3 and begins to transfer the trays in the same way. This process continues until a maximum of 5 conveyor belts 9 are filled. Then, a settling process is carried out, generally for 48 hours. When discharging, the conveyor belt 9 of the conveying device 3 is controlled to move to the left, and the second transfer unit 7 picks up the trays for discharging. In this process, the trays are transferred sequentially from the bottom to the top, effectively following the first-in, first-out principle.

[0018] It should be noted that the width of the conveyor belt 9 in this invention corresponds to the size of the material tray. The size of the conveyor belt 9 can be increased or decreased as needed. The material and implementation method of the conveyor belt 9 are existing general technical means, such as: treadmill or express parcel conveyor belt 9; the material tray is rectangular, and multiple layers of material trays can be stacked.

[0019] In one embodiment, a feeding section 11 is provided on one side of the first transfer section 10; and a discharging section 8 is provided on one side of the second transfer section 7.

[0020] Furthermore, the feeding section 11 includes a conveyor belt 9 and a base 12, with the conveyor belt 9 disposed on the base 12 and moving towards one side of the first transfer section 10; the discharging section 8 includes a conveyor belt 9 and a base 12, with the conveyor belt 9 disposed on the base 12 and moving towards one side of the second transfer section 7.

[0021] In one embodiment, the conveying device 3 further includes a support 2, which is fixed to the conveyor belt 9.

[0022] It should be noted that the support 2 is a rigid structure, the material of the support 2 is metal, the bottom of the support 2 is directly on the ground, and it is installed on both sides of the conveyor device 3 to fix the conveyor belt 9 of the conveyor device 3.

[0023] In one embodiment, the lifting part 5 includes a lifting frame 6, a lifting chain 4 and a motor 1. The motor 1 is located on the upper part of the lifting frame 6, and one end of the lifting chain 4 is connected to the motor 1.

[0024] It should be noted that the lifting chain 4 is a chain structure, and the motor 1 meshes with the lifting chain 4. This meshing structure is a common existing technology, such as the chain of a bicycle; the motor 1 is a servo motor 1.

[0025] In one embodiment, a control unit 13 is also included. The control unit 13 is electrically connected to the discharge unit 8 and the feed unit 11, the first transfer unit 10 and the second transfer unit 7, the conveyor belt 9, and the motor 1.

[0026] It should be noted that the control unit 13 not only provides power to the above components, but can also be controlled manually or by machine programming.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
