Description

Technical Field

[0001] This utility model relates to the field of FPC processing technology, specifically to a dual-channel feeding device. Background Technology

[0002] FPC (Flexible Printed Circuit) is a type of flexible electronic interconnect component made from a flexible substrate (such as polyimide PI, polyester PET, etc.) through processes such as etching. It is lightweight, flexible, and resistant to high and low temperatures, and is widely used in consumer electronics, automotive electronics, medical devices, and other fields.

[0003] After FPC laser processing, the products need to be unloaded. In the existing technology, conveyor belts are used to transport the unloaded FPCs. In order to improve efficiency, the existing technology uses two or more conveyor belts to transport OK products (good products), and an additional conveyor belt is needed to transport NG products (defective products). This takes up a lot of space and is costly. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a dual-channel feeding device that uses a multi-moving linear motor and a lifting platform to achieve alternating and rapid conveying of products, thereby improving efficiency and resulting in a compact structure and small size.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A dual-channel unloading device includes a base, two linear motors, and two lifting platform modules. The two linear motors are arranged side by side on both sides of the base, and the lifting platform modules are respectively mounted on the movers of the two linear motors. Each lifting platform module includes a lifting mechanism and a platform. The lifting mechanism is mounted on the movers of the linear motors, and the platform is mounted on the lifting mechanism. The lifting mechanism drives the platform to move vertically, and the platform is used to place a product storage tray. The platform is eccentrically positioned on the lifting mechanism, closer to the opposite side of the lifting mechanism.

[0007] As a further improvement to the above technical solution, one of the linear motors has two movers, and a lifting platform module is also provided on the other mover of the linear motor.

[0008] As a further improvement to the above technical solution, the lifting mechanism includes a fixed plate, a support frame, and a lifting cylinder. The fixed plate is connected to the mover of the corresponding linear motor. The support frame is slidably connected to the fixed plate in the vertical direction. The fixed end of the lifting cylinder is connected to the fixed plate. The telescopic end of the lifting cylinder is connected to the platform. The platform is fixedly connected to the top of the support frame.

[0009] As a further improvement to the above technical solution, a linear guide rail is provided between the support frame and the fixed plate. The linear guide rail includes a slide rail disposed on the fixed plate and a slider disposed on the support frame. The slider is slidably connected to the slide rail.

[0010] As a further improvement to the above technical solution, two photoelectric switches are arranged vertically on the fixed plate, and a photoelectric sensor is arranged on the support frame. When the photoelectric sensor passes through the sensing areas of the two photoelectric switches, it is used to control the rising and falling height of the platform.

[0011] As a further improvement to the above technical solution, the platform includes a support plate and a carrier plate. The support plate is fixedly connected to the support frame, and the carrier plate is connected to the support plate. The top of the carrier plate is provided with a positioning groove for placing a product storage tray.

[0012] As a further improvement to the above technical solution, a negative pressure adsorption hole is provided at the bottom of the positioning groove, and the negative pressure adsorption hole is connected to an external vacuum device.

[0013] As a further improvement to the above technical solution, a positioning block is provided in the positioning groove, a positioning cylinder is provided at the bottom of the carrier plate, and a positioning column is provided at the telescopic end of the positioning cylinder. When the positioning cylinder telescopically extends or retracts, it is used to drive the positioning column to move so as to push the product storage tray to move towards the positioning block.

[0014] As a further improvement to the above technical solution, the platform also includes a push cylinder. The carrier plate is slidably connected to the support plate, the push cylinder is mounted on the support plate, and the telescopic end of the push cylinder is connected to the carrier plate. When the push cylinder telescopically extends or retracts, it is used to drive the carrier plate to move along the X direction.

[0015] The beneficial effects of this utility model are: two linear motors drive two platforms to move respectively, realizing dual-channel unloading. The platforms are eccentrically set on the lifting mechanism with their sides closer to the lifting mechanism, which greatly reduces the space occupied on the horizontal plane. The platforms are lifted and lowered by the lifting mechanism. When the two platforms move to the same position, they can be staggered to avoid each other. Therefore, the dual-channel unloading device of this utility model has a more compact structure and can shorten the stroke of the unloading robot. Attached Figure Description

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figure 1 This utility model provides a dual-channel unloading device, including a base 100, two linear motors, and three lifting platform modules. The two linear motors are a first linear motor 200 and a second linear motor 300, mounted side-by-side on both sides of the base 100. The first linear motor 200 has two rotors, a first rotor and a third rotor, while the second linear motor 300 has a second rotor, both of which are positioned opposite to the first and third rotors. The three lifting platform modules are a first lifting platform 400, a second lifting platform 500, and a third lifting platform 600. The first lifting platform 400 is mounted on the first rotor, the second lifting platform 500 is mounted on the second rotor, and the third lifting platform 600 is mounted on the third rotor.

[0028] The lifting platform module includes a lifting mechanism and a platform 440. The lifting mechanism is mounted on the mover of a linear motor and is driven to move by the linear motor. The platform 440 is mounted on the lifting mechanism and is driven to move vertically by the lifting mechanism. The platform is used to place product storage trays. Furthermore, the platform 440 is eccentrically positioned on the lifting mechanism, closer to the opposite side of the lifting mechanism. That is, the platforms 440 on the linear motors on both sides of the base 100 are eccentrically positioned between the two linear motors.

[0029] In this embodiment, the first linear motor 200 drives the first lifting platform 400 to move along its length. The first lifting platform 400 is used to load good materials. After the first lifting platform 400 is fully loaded, the lifting mechanism lowers the height of the platform 440 in the first lifting platform 400 and conveys the material. At this time, the second linear motor 300 drives the second lifting platform 500 to continue loading good materials. After the second lifting platform 500 is fully loaded, the lifting mechanism lowers the height of the platform 440 in the second lifting platform 500 and conveys the material. This realizes a dual-channel alternating feeding action to improve feeding efficiency.

[0030] However, in this embodiment, the platforms 440 on the two linear motors are eccentrically positioned on their respective lifting mechanisms, closer to the opposite lifting mechanism. That is, the platforms 440 on the linear motors located on both sides of the base 100 are eccentrically positioned between the two linear motors. Therefore, the space occupied by the platforms 440 on the horizontal plane is significantly reduced. Furthermore, both the first lifting platform 400 and the second lifting platform 500 have lifting functions. During movement, the height of the first lifting platform 400 and the second lifting platform 500 can be controlled vertically to avoid collisions and ensure the stability of the material unloading process.

[0031] In this embodiment, the third lifting platform 600 unloads NG (defective) products, while the first lifting platform 400 and the second lifting platform 500 unload OK (good) products. Specifically, each of the first lifting platform 400, the second lifting platform 500, and the third lifting platform 600 includes a lifting mechanism and a platform 440. The platform 440 is located at the telescopic end of the lifting mechanism. The lifting mechanism drives the platform 440 to move up and down, thereby moving the platform 440 to the material handling or unloading position, and allows the platforms 440 of the first lifting platform 400 and the second lifting platform 500 to be staggered to avoid each other.

[0032] Specifically, the lifting mechanisms of the first lifting platform 400, the second lifting platform 500, and the third lifting platform 600 have the same structure. Taking the lifting mechanism of the first lifting platform 400 as an example, refer to... Figure 2The lifting mechanism of the first lifting platform 400 includes a fixed plate 410, a support frame 420, and a lifting cylinder 450. It can be understood that the fixed plates 410 of the lifting mechanisms of the first lifting platform 400, the second lifting platform 500, and the third lifting platform 600 are respectively connected to the first moving element, the second moving element, and the third moving element. The support frame 420 is slidably connected to the fixed plate 410 in the vertical direction via a first linear guide rail 430. The platform 440 is fixedly connected to the top of the support frame 420. The fixed end of the lifting cylinder 450 is connected to the fixed plate 410, and the telescopic end of the lifting cylinder 450 is connected to the platform 440. Thus, when the lifting cylinder 450 extends or retracts, it can drive the platform 440 to move up and down.

[0033] Furthermore, the first linear guide rail 430 includes a slide rail disposed on the fixed plate 410 and a slider disposed on the support frame 420, wherein the slider is slidably connected to the slide rail.

[0034] In a preferred embodiment, a first photoelectric switch 460 and a second photoelectric switch 470 are provided on the fixed plate 410 along the vertical direction, and the first photoelectric switch 460 and the second photoelectric switch 470 are electrically connected to the controller of the lifting cylinder 450. A photoelectric sensor 480 is provided on the support frame 420. When the photoelectric sensor 480 moves up and down with the support frame 420, it passes through the sensing areas of the first photoelectric switch 460 and the second photoelectric switch 470 respectively, so as to control the rising and falling height of the platform 440.

[0035] In this embodiment, the platform 440 of the first lifting platform 400 and the platform 440 of the third lifting platform 600 have the same structure. Taking the platform 440 of the first lifting platform 400 as an example, refer to... Figure 3 The platform 440 includes a first support plate 441 and a first carrier plate 442. The first support plate 441 is fixedly connected to the support frame 420, and the first carrier plate 442 is connected to the first support plate 441. The top of the first carrier plate 442 is provided with a first positioning groove 443 for placing a product storage tray. The bottom of the first positioning groove 443 is provided with a first negative pressure adsorption hole 444. The first negative pressure adsorption hole 444 is connected to an external vacuum device. The external vacuum device controls the generation of negative pressure at the first negative pressure adsorption hole 444, thereby adsorbing the product storage tray. In this way, after the unloading robot places the FPC product in the product storage tray, multiple products can be adsorbed through the product storage tray, which facilitates better stability of the FPC product when the platform 440 moves quickly.

[0036] Furthermore, a first positioning block 445 is provided in the first positioning groove 443, and a first positioning cylinder 447 is provided at the bottom of the first carrier plate 442. A first positioning post 446 is provided at the telescopic end of the first positioning cylinder 447. When the first positioning cylinder 447 telescopically extends, it is used to drive the first positioning post 446 to move so as to push the product storage tray to move towards the first positioning block 445, thereby facilitating the positioning of the product storage tray in the first positioning groove 443.

[0037] In this embodiment, refer to Figure 4 and Figure 5 The platform 440 of the second lifting platform 500 includes a second support plate 541 and a second carrier plate 542. The second support plate 541 is fixedly connected to the support frame 420. The second carrier plate 542 is connected to the second support plate 541 through a second linear guide rail 549. The top of the second carrier plate 542 is provided with a second positioning groove 543 for placing a product storage tray. The bottom of the second positioning groove 543 is provided with a second negative pressure adsorption hole 544. The second negative pressure adsorption hole 544 is connected to an external vacuum device. The external vacuum device controls the generation of negative pressure at the second negative pressure adsorption hole 544, thereby adsorbing the product storage tray. In this way, after the unloading robot places the FPC product in the product storage tray, multiple FPC products can be adsorbed through the product storage tray, which facilitates better stability of the FPC products when the platform 440 moves quickly.

[0038] Furthermore, a second positioning block 545 is provided in the second positioning groove 543, and a second positioning cylinder 547 is provided at the bottom of the second carrier plate 542. A second positioning post 546 is provided at the telescopic end of the second positioning cylinder 547. When the second positioning cylinder 547 telescopically extends, it is used to drive the second positioning post 546 to move so as to push the product storage tray to move towards the second positioning block 545, thereby facilitating the positioning of the product storage tray in the second positioning groove 543.

[0039] In some embodiments, the platform 440 of the second lifting platform 500 further includes a push cylinder 548, and the second carrier plate 542 is slidably connected to the second support plate 541. The push cylinder 548 is mounted on the second support plate 541, and the telescopic end of the push cylinder 548 is connected to the second carrier plate 542. When the push cylinder 548 telescopically extends or retracts, it is used to drive the second carrier plate 542 to move along the X direction (the X direction is perpendicular to the length direction of the first linear motor 200 on the horizontal plane).
