Description

Technical Field

[0001] This utility model relates to the field of scissor bracket material collection technology, and in particular to a keyboard scissor bracket material collection device. Background Technology

[0002] A keyboard scissor-switch bracket is a support structure for keyboard keys, named for its scissor-like shape. It typically consists of two hinged parts installed between the keycaps and the keyboard base. It supports the smooth up-and-down movement of the keycaps, ensuring consistent key feel and improving the typing experience. It is an important component of common keyboard types such as mechanical and membrane keyboards. In the keyboard manufacturing process, the keyboard scissor-switch bracket, as a crucial component, has a significant impact on production efficiency and product quality during the material handling stage.

[0003] In current industry practice, the keyboard scissor bracket receiving process is mostly done manually. After production, workers need to pick up the brackets one by one and stack them neatly. This method not only consumes a lot of manpower and has low work efficiency, but also, due to the difficulty in standardizing the force and technique of manual operation, the brackets are easily scratched or bent during handling, which seriously affects the product yield. Some companies have tried to use modified bolt feeding machines for receiving, but this equipment is limited by its structural design and can only be used for a single specification of bracket. Multiple bolt feeding machines need to be equipped according to product specifications, which takes up a lot of space and cannot meet the production receiving needs of companies for multiple models of keyboard products.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-6 A keyboard scissor bracket receiving device includes a material distribution box 1 and a material distribution hopper 2. The inner bottom wall of the material distribution hopper 2 is provided with a discharge port 3. The inside of the material distribution box 1 is provided with an upper through hole 11. The material distribution box 1 and the material distribution hopper 2 are connected by a telescopic connecting cylinder 4. This design can adapt to the height difference generated when the material distribution hopper 2 vibrates, ensuring the stability of the material discharge path.

[0030] A vibration motor 19 is installed on the outer surface of the hopper 2. Two second extension plates 10 are fixedly connected to the outer surface of the hopper 2. Two first extension plates 5 are fixedly connected to the outer surface of the distribution box 1. By setting the extension plates, the installation base for the vibration coordination mechanism is provided to ensure the stability of the structural connection.

[0031] A vibration engagement mechanism is provided between each corresponding first extension plate 5 and second extension plate 10. The vibration engagement mechanism includes a sleeve 6, the bottom surface of which is fixedly connected to the upper surface of the first extension plate 5. A connecting rod 9 is slidably connected to the inner wall of the sleeve 6. The displacement buffering of the material distribution hopper 2 during vibration is achieved by utilizing the sliding engagement between the sleeve 6 and the connecting rod 9.

[0032] The top of the connecting rod 9 is fixedly connected to the bottom surface of the second extension plate 10. A damper 7 is fixedly connected to the bottom surface of the connecting rod 9. The bottom end of the damper 7 is fixedly connected to the inner bottom wall of the sleeve 6. The damper 7 can attenuate the impact force transmitted by the vibration of the distribution hopper 2 and reduce the shaking of the equipment during operation.

[0033] A buffer spring 8 is fitted on the outer surface of the damper 7. The two ends of the buffer spring 8 are fixedly connected to the bottom surface of the connecting rod 9 and the inner bottom wall of the sleeve 6. The buffer spring 8 cooperates with the damper 7 to further absorb vibration energy and ensure the stability of the internal structure of the material distribution box 1.

[0034] A first servo motor 12 is installed on the back of the material distribution box 1. The output end of the first servo motor 12 is fixedly connected to the feeding rotating column 13. The outer surface of the feeding rotating column 13 is rotatably connected to the material distribution box 1. The first servo motor 12 provides power to the feeding rotating column 13, enabling rotational feeding control.

[0035] The inside of the feeding column 13 is provided with a set of bearing ports 14. A thin film sensor 16 is installed on the inner wall of the bearing port 14. A carrier plate 15 is installed on the top of the thin film sensor 16. When the carrier plate 15 is pressed, it triggers the thin film sensor 16, which can accurately detect whether the bracket has fallen into the bearing port 14. The outer surface of the carrier plate 15 is slidably connected to the bearing port 14 to ensure that the carrier plate 15 can stably trigger the sensor when it is pressed, thus avoiding false detection.

[0036] The material distribution box 1 has a material discharge port 17 inside, and a vision camera 18 is installed inside the material distribution box 1. The front of the material distribution box 1 has a light transmission port 34, which provides a light channel for the vision camera 18 to ensure the accuracy of the bracket's front and back recognition.

[0037] The material distribution box 1 is equipped with a horizontal feeding mechanism, which includes a second servo motor 21. The second servo motor 21 is installed on the outer surface of the material distribution box 1. The second servo motor 21 drives the slider 23 through the threaded rod 22 to provide guidance for the horizontal movement of the conveying trough 26.

[0038] The output end of the second servo motor 21 is fixedly connected to a threaded rod 22. The outer surface of the threaded rod 22 is rotatably connected to the material distribution box 1. The material distribution box 1 has an internal slot 20. The inner wall of the internal slot 20 is slidably connected to a slider 23. The threaded rod 22 and the slider 23 are threadedly engaged, which can convert the rotational motion into linear motion.

[0039] The threaded rod 22 is threadedly connected to the slider 23. The outer surface of the slider 23 is fixedly connected to the conveying trough 26. The slider 23 drives the conveying trough 26 to move, so that the bracket is accurately aligned with the flipping trough 30 or the front trough 31.

[0040] An electric push rod 27 is installed inside the conveying trough 26. The output end of the electric push rod 27 is fixedly connected to a lower baffle 28 through a connector. The lower baffle 28 is in contact with the conveying trough 26. The electric push rod 27 drives the lower baffle 28 to open and close, which can control the timing of the support feeding.

[0041] A recognition sensor 24 is installed on the back of the slider 23, and a set of markers 25 is installed on the inner wall of the back of the material distribution box 1. The recognition sensor 24 and the markers 25 work together to achieve precise positioning of the moving position of the conveying trough 26.

[0042] Inside the material distribution box 1 is a set of front and back sorting blocks 29. Each front and back sorting block 29 has a flipping groove 30 and a front groove 31. Through the two groove structures, the supports in different directions can be sorted to ensure that the front faces up when output.

[0043] Each positive and negative sorting block 29 has a fixed connection to a feeding block 32 on its bottom surface. Each feeding block 32 has a discharge groove 33 inside. The discharge groove 33 has a structure that is larger at the top and smaller at the bottom, which can be adapted to different specifications of brackets to ensure that when the material is discharged to the bottom outlet, the scissor bracket is in the position corresponding to the receiver.

[0044] A sliding blocking block 37 is slidably connected to the inner wall of the distributing hopper 2. A hand-tightening bolt 35 is rotatably connected to the outer surface of the sliding blocking block 37. The hand-tightening bolt 35 passes through the distributing hopper 2 and is threadedly connected to the distributing hopper 2. Rotating the hand-tightening bolt 35 can adjust the position of the sliding blocking block 37, and the material feeding width can be manually controlled. A folding curtain 36 is fixedly connected to the outer surface of the sliding blocking block 37. One section of the folding curtain 36 is fixedly connected to the distributing hopper 2. The folding curtain 36 moves with the sliding blocking block 37, which can prevent small-sized brackets from feeding side by side and avoid material jamming in subsequent structures.

[0045] Working principle: The completed keyboard scissor brackets are put into the dispensing hopper 2. The inner wall of the dispensing hopper 2 is equipped with a sliding blocking block 37. The position of the sliding blocking block 37 can be adjusted by rotating the hand-tightening bolt 35. In conjunction with the folding curtain 36, the material feeding amount is controlled. When processing small brackets, unfolding the folding curtain 36 can prevent multiple brackets from falling into the subsequent structure side by side and avoid material jamming.

[0046] Start the vibration motor 19 on the outer surface of the material distribution hopper 2. The vibration causes the scissor brackets to pass through the discharge port 3 on the bottom wall of the material distribution hopper 2 one by one, and fall into the bearing port 14 in the material distribution box 1 through the telescopic connecting cylinder 4. The telescopic connecting cylinder 4 between the material distribution box 1 and the material distribution hopper 2 can adapt to different height differences caused by shaking, ensuring smooth material discharge.

[0047] The bearing port 14 is opened on the outer surface of the feeding rotating column 13. A carrier plate 15 is set above the thin film sensor 16 installed on its inner wall. When the scissor bracket falls into the bearing port 14, the carrier plate 15 is pressed and triggers the thin film sensor 16. The sensor signal is fed back to the control system, and then the vibration motor 19 is stopped to avoid excessive feeding.

[0048] The first servo motor 12 is started, and its output drives the feeding column 13 to rotate, so that the scissor bracket in the bearing port 14 rotates with the column to the dropping port 17 inside the material distribution box 1. The bracket falls from the dropping port 17 into the conveying trough 26 of the horizontal feeding mechanism. The vision camera 18 installed inside the material distribution box 1 takes pictures of the scissor bracket falling into the conveying trough 26, identifies its front and back directions, and transmits the signal to the controller.

[0049] Based on the detection results from the vision camera 18, the controller activates the second servo motor 21. The threaded rod 22 at its output rotates, causing the slider 23, which is threadedly connected to the threaded rod 22, to slide laterally within the built-in slot 20 of the material distribution box 1. This, in turn, pushes the conveying trough 26 to the corresponding position. If the support needs to be flipped, it moves to the flipping groove 30 of the front and back sorting block 29; if the support is oriented correctly, it moves to the front groove 31. The identification sensor 24 on the back of the slider 23 works in conjunction with the marker 25 on the inner wall of the material distribution box 1 to ensure precise positioning.

[0050] The electric push rod 27 inside the conveying trough 26 is activated, and its output end pushes the lower baffle 28 to open. The scissor bracket falls into the front and back sorting block 29. The front slide 31 allows the bracket with the correct orientation to pass directly face up. The flip slide 30, through its internal structure, flips the bracket with the wrong orientation so that its face is up. Finally, they all fall into the external receiving box through the discharge trough 33 of the discharge block 32. The discharge trough 33 is designed with a guide structure that is larger at the top and smaller at the bottom, which can accommodate brackets of different specifications. Small brackets can slide smoothly down the trough wall.

[0051] The material distribution box 1 and the material distribution hopper 2 are connected by a vibration engagement mechanism: a sleeve 6, a connecting rod 9, a damper 7, and a buffer spring 8 are installed between the first extension plate 5 and the second extension plate 10. When the vibration motor 19 is working, the damper 7 and the buffer spring 8 can absorb the vibration impact force of the material distribution hopper 2, reduce the impact on the internal structure of the material distribution box 1, ensure the stable operation of the equipment, and prevent the support frame from being damaged by severe vibration.
