Description

Technical Field

[0001] This invention relates to the field of automated keyboard assembly machine tools, specifically a screw-driving device for keyboard production and assembly. Background Technology

[0002] The keyboard is the most commonly used and primary input device. Through the keyboard, English letters, Chinese characters, numbers, punctuation marks, etc., can be entered into the computer, thereby issuing commands and inputting data. Over time, independent products with various shortcut functions have gradually appeared on the market and are sold separately, along with dedicated drivers and configuration software, enabling personalized operations on compatible machines.

[0003] The keyboard's circuit board has hundreds of switches soldered on it, and keycaps are mounted on the switches. People type on it thousands of times every day. The screws on the keyboard provide strong clamping force, firmly compressing the top cover, positioning plate, PCB, and bottom cover into a whole, preventing deformation, loosening, or abnormal noise due to long-term stress. Therefore, during the production and assembly of the keyboard, the screws on the bottom cover need to be tightened. The existing screw-driving device first places the keyboard on a mold, moves the mold under an electric screwdriver, and the electric screwdriver picks up the screws and inserts them into the keyboard's mounting slots one by one. Since both the top and bottom covers of the keyboard need to be tightened with screws, the existing screw-driving device can only tighten the screws on the top surface of the keyboard first. After manually flipping it over, the screws on the bottom surface can be tightened. It lacks the function of flipping the entire keyboard, resulting in low assembly efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a screw-driving device for keyboard production and assembly, so as to solve the problems mentioned in the background art.

The bottom end of the electric telescopic rod is fixedly installed on the top of the moving platform. A one-way gear is fixedly installed on the outer side of the rotating rod. Two one-way racks, each cooperating with one of the two one-way gears, are fixedly installed on the top of the moving platform.

[0008] Preferably, the pressing mechanism further includes multiple elastic telescopic rods fixedly installed at equal intervals between the clamping plate and the inner side of the movable box. An installation rod is rotatably installed on the inner side of the movable box. The outer side of the installation rod is fixedly connected to two adjacent pressure plates. Two symmetrically distributed rack plates are fixedly installed on the side of the clamping plate near the elastic telescopic rod. The two rack plates are respectively located below the two pressure plates. An arc-shaped rack that cooperates with the rack plate is fixedly installed on the end of the pressure plate near the installation rod. A groove is opened on the outer side of the movable box for the pressure plate to slide and limit its movement. Two symmetrically distributed support plates are fixedly installed on the bottom of the movable box. The two support plates are respectively located directly below the two pressure plates.

[0009] Preferably, the base support mechanism further includes two folding rods symmetrically rotatably mounted on the outside of the rotating rod. A push rod is hinged to one end of each folding rod away from the rotating rod. A mounting plate is fixedly mounted between the push rod and the bottom of the bracket. A sleeve block is rotatably mounted at the folding point of each folding rod. Two symmetrically distributed sliding rods are slidably mounted between the two sleeve blocks. A bracket is fixedly mounted between both ends of each sliding rod. The bottom of the bracket is fixedly mounted to the top of the moving platform. Two symmetrically distributed positioning frames are fixedly mounted on the top of the moving platform. The two push rods are slidably mounted on the inner sides of the two positioning frames. A plurality of contact rods arranged in a rectangular array are fixedly mounted on the top of the bracket.

[0010] Preferably, two symmetrically distributed guide plates are fixedly installed on the inner side of the placement frame, and the outer side of the guide plates has an inclined structure.

[0015] Preferably, a buffer pad is fixedly installed at the top end of the contact rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention uses a flipping mechanism to move an electric screwdriver to a screw feeder in conjunction with a vertical slide to magnetically attract the screws and assemble them sequentially into the mounting slots on the top surface of the keyboard. Then, the keyboard is flipped over by a placement frame so that the bottom surface of the keyboard faces upwards, allowing for screw assembly on the bottom surface of the keyboard. This achieves a double-sided assembly effect and improves the keyboard assembly efficiency.

[0018] This invention uses a pressing mechanism to cause the clamping plate to swing downwards and contact the top surface of the keyboard when it comes into contact with the outside of the keyboard. This, together with the support plate at the bottom of the movable box, achieves horizontal positioning of the keyboard and ensures tightness between the upper and lower covers of the keyboard. This improves the accuracy of the screws in assembling the keyboard and prevents loosening.

[0019] This invention, through its base support mechanism, provides support for the side of the keyboard away from the electric screwdriver via a contact rod at the top of the bracket. It also allows the bracket to move away from the placement frame when the keyboard is flipped, ensuring a smooth flip and thus improving the stability of keyboard screw assembly.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1-8 The diagram illustrates a screw-driving device for keyboard production and assembly, comprising a machine tool 1 and an electric slide 2 fixedly mounted on the top of the machine tool 1. A vertical slide 3 is mounted on the outer side of the electric slide 2, and an electric screwdriver 4 is mounted on the outer side of the vertical slide 3. A screw feeder 5 is mounted on the inner side of the machine tool 1. The position of the electric screwdriver 4 is adjusted by the electric slide 2 and the vertical slide 3, and the screws on the screw feeder 5 are magnetically attracted. A movable stage 6 is slidably mounted on the inner side of the machine tool 1, allowing the movable stage 6 to adjust the position of the keyboard, facilitating the electric screwdriver 4 to lock the screws into multiple mounting slots on the keyboard. The device also includes a flipping mechanism for flipping the keyboard for assembly, and the flipping mechanism is mounted on the top of the movable stage 6.

[0031] The flipping mechanism includes a placement frame 7 located on top of the moving platform 6. The placement frame 7 can position and flip the keyboard, facilitating double-sided assembly of the top and bottom surfaces of the keyboard by the electric screwdriver 4. The flipping mechanism also includes two symmetrically arranged moving boxes 10 inside the placement frame 7. Each moving box 10 has a clamping plate 11 on one corresponding side. Slider 12 is fixedly installed on both sides of the moving box 10. A sliding groove for limiting the sliding of the slider 12 is fixedly installed inside the placement frame 7. Two symmetrically distributed opposite screws 13 are rotatably installed inside the placement frame 7. The two sliders 12 on the moving box 10 are respectively threaded onto... The threads at both ends of the two counter-rotating screws 13, and the inner side of the slide groove, are fixedly installed with a sliding optical shaft for limiting the sliding of the slider 12. When the two counter-rotating screws 13 rotate, the slider 12 can drive the two moving boxes 10 to move closer to each other on the outside of the keyboard. The two moving boxes 10 are clamped and positioned on the outside of the keyboard by the clamping plate 11, which facilitates fixing keyboards of more sizes in the placement frame 7. Drive motors 14 are fixedly installed on both sides of the placement frame 7. The two drive motors 14 are respectively fixedly connected to one end of the two counter-rotating screws 13, so that the two drive motors 14 can adjust the rotation of the two counter-rotating screws 13 respectively. A rotating rod 15 is fixedly installed on each side. An electric telescopic rod 16 is rotatably installed at the end of the rotating rod 15 away from the placement frame 7. The bottom end of the electric telescopic rod 16 is fixedly installed on the top of the moving platform 6. A one-way gear 17 is fixedly installed on the outer side of the rotating rod 15. Two one-way racks 18 are fixedly installed on the top of the moving platform 6, each meshing with a one-way gear 17. The electric telescopic rod 16 can push the placement frame 7 upward through the rotating rod 15, causing the one-way gear 17 on the rotating rod 15 to rotate along the outer side of the one-way rack 18 and move upward. The one-way gear 17 can then drive the rotating rod 15 to rotate half a turn, thereby flipping the placement frame 7. The electric telescopic rod 16 then resets the rotating rod 15 downwards. Utilizing the cooperation of the one-way gear 17 and the one-way rack 18, the bottom surface of the keyboard inside the placement frame 7 is reset to face upwards and downwards. The electric screwdriver 4 can then assemble the bottom surface of the keyboard with screws. Two symmetrically distributed guide plates 32 are fixedly installed on the inner side of the placement frame 7, and the outer side of the guide plates 32 has a sloping structure, which facilitates the placement of the keyboard into the placement frame 7. The two drive motors 14 are centrally symmetrically distributed, and a balance block 33 is fixedly installed on the end of the opposite-direction screw 13 away from the drive motor 14 to ensure that the weight on both sides of the placement frame 7 is the same, thereby improving the stability of the placement frame 7 when flipping.

[0032] Example 2: Please refer to Figures 3-6This embodiment further illustrates Example 1. The pressing mechanism shown in the figure includes four pressure plates 8 symmetrically arranged on the outside of the placement frame 7. The pressure plates 8 can press the top and bottom surfaces of the keyboard. The pressing mechanism also includes multiple elastic telescopic rods 19 equidistantly fixed between the clamping plate 11 and the inner side of the moving box 10. An installation rod 20 is rotatably installed on the inner side of the moving box 10. The outer side of the installation rod 20 is fixedly connected to two adjacent pressure plates 8. Two symmetrically distributed rack plates 21 are fixedly installed on the side of the clamping plate 11 near the elastic telescopic rods 19. 21 is located below the two pressure plates 8 respectively, and an arc-shaped rack 22 that cooperates with the rack plate 21 is fixedly installed on the end of the pressure plate 8 near the mounting rod 20. The outer side of the moving box 10 is provided with a groove for the pressure plate 8 to slide in a limited position. When the clamping plate 11 contacts the outer side of the keyboard, the reaction force of the keyboard on the clamping plate 11 compresses the elastic telescopic rod 19 and brings the clamping plate 11 closer to the moving box 10. The clamping plate 11 drives the rack plate 21 to move synchronously, so that the rack plate 21 drives the pressure plate 8 to swing downward with the mounting rod 20 as the fulcrum. The pressure plate 8 contacts the top surface of the keyboard. Two symmetrically distributed trays 23 are fixedly installed at the bottom of the movable box 10, and the two trays 23 are located directly below the two pressure plates 8. When the keyboard is placed in the placement frame 7, it can contact the pressure plates 8 at the bottom of the two movable boxes 10. When the pressure plates 8 are close to the top surface of the keyboard, the pressure plates 8, together with the trays 23, press the top and bottom surfaces of the keyboard tightly together, ensuring that the upper and lower covers of the keyboard are tightly attached, improving the precision of screw assembly, and preventing the keyboard from becoming loose. Anti-slip pads 34 are fixedly installed on the outer sides of the clamping plate 11, the pressure plates 8, and the trays 23. The anti-slip grooves of the anti-slip pads 34 on the clamping plate 11 are horizontally distributed, while the anti-slip grooves of the anti-slip pads 34 on the pressure plate 8 and the support plate 23 are vertically distributed. This allows the clamping plate 11, the pressure plate 8, and the support plate 23 to firmly grip the outer side of the keyboard through the corresponding anti-slip pads 34, preventing the keyboard from slipping when flipped. A guide frame 35 is fixedly installed on the outer side of the moving box 10, and the guide frame 35 is on the same horizontal line as the clamping plate 11. This facilitates the clamping plate 11 to be retracted into the guide frame 35, and allows the guide frame 35 to provide support for the clamping plate 11, preventing the clamping plate 11 from becoming loose.

[0033] Example 3: Please refer to Figures 2-8This embodiment further illustrates other embodiments. The bottom support mechanism shown in the figure is mounted on the movable platform 6. The bottom support mechanism includes a bracket 9 disposed on the top of the movable platform 6, which provides support for the keyboard. The bottom support mechanism also includes two symmetrically rotatably mounted folding rods 24 on the outside of the rotating rod 15. A push rod 25 is hinged to one end of each folding rod 24 away from the rotating rod 15. A mounting plate 26 is fixedly mounted between the push rod 25 and the bottom of the bracket 9. A sleeve block 27 is rotatably mounted at the folding point of the folding rod 24. Two sleeve blocks 27 are slidably mounted between the two sleeve blocks 27. Two symmetrically distributed sliding rods 28 are provided, with brackets 29 fixedly installed between the two ends of each sliding rod 28. The bottom of the brackets 29 is fixedly installed on the top of the moving platform 6. When the rotating rod 15 moves upward, it can pull the two folding rods 24 to swing upward. The folding point of the folding rods 24 drives the sleeve block 27 to move along the outside of the sliding rod 28. The bottom ends of the two folding rods 24 can push the push rod 25 downward, so that the push rod 25 moves the bracket 9 away from the bottom of the placement frame 7, which facilitates the upward movement and flipping of the placement frame 7. When the rotating rod 15 returns to its original position, the bracket 9... The top of the moving platform 6 is fixedly equipped with two symmetrically distributed positioning frames 30, which can be moved closer to the bottom of the placement frame 7. Two push rods 25 are slidably installed on the inner side of the two positioning frames 30, so that the push rods 25 can move along the inner side of the positioning frames 30 when moving. The positioning frames 30 provide horizontal support for the bracket 9 through the push rods 25 and the mounting plate 26. The top of the bracket 9 is fixedly equipped with multiple contact rods 31 arranged in a rectangular array, so that the bracket 9 can contact the side of the keyboard away from the electric screwdriver 4 through the contact rods 31. 1. The bracket 9 provides support for the keyboard, facilitating the smooth threading assembly of the keyboard by the electric screwdriver 4. Two symmetrically distributed top plates 36 are fixedly installed on the top of the bracket 9. The top of the top plate 36 contacts the bottom of the placement frame 7, so that the bracket 9 contacts the bottom of the placement frame 7 through the top plate 36, providing support for the bottom of the placement frame 7 and ensuring that the placement frame 7 is in a horizontal state. A buffer pad 37 is fixedly installed on the top of the contact rod 31, so that the contact rod 31 can contact the side of the keyboard away from the electric screwdriver 4 through the buffer pad 37, providing protection for the keyboard.

[0034] Working principle: First, the operator places the keyboard in the placement frame 7, ensuring the bottom surface of the keyboard contacts the four support plates 23. Then, the operator activates the two drive motors 14, causing the corresponding counter-rotating screws 13 to rotate. The counter-rotating screws 13 drive the corresponding two sliders 12 to move closer together along the inner side of the groove in the placement frame 7 and the outer side of the optical axis. The four sliders 12 drive the two moving boxes 10 to move closer together, causing the clamping plates 11 on the outer side of the moving boxes 10 to contact the outer side of the keyboard. The two clamping plates 11 clamp and position the outer side of the keyboard. Utilizing the reaction force of the keyboard on the clamping plates 11, the clamping plates 11 move against the elastic telescopic rod 19. The keyboard is compressed and moved into the inner side of the movable box 10. At the same time, the clamping plate 11 drives the two rack plates 21 to move synchronously. The rack plates 21 drive the pressure plate 8 to swing downward with the mounting rod 20 as the fulcrum, so that the pressure plate 8 contacts the top surface of the keyboard. The pressure plate 8 can then cooperate with the support plate 23 to press and position the top and bottom surfaces of the keyboard, ensuring the tightness between the upper and lower covers of the keyboard. Subsequently, the processing machine tool 1 moves the moving table 6 below the electric screwdriver 4, and the electric slide 2 moves the vertical slide 3 below the screw feeder 5. The vertical slide 3 drives the electric screwdriver 4 to move downward, so that the electric screwdriver 4 magnetically attracts the screws on the screw feeder 5, and then the electric screwdriver 4... The blade 4 moves to the screw mounting slot on the top surface of the keyboard and assembles the screws sequentially. After the screws on the top surface of the keyboard are assembled, the two electric telescopic rods 16 push the corresponding rotating rods 15 upward, causing the two rotating rods 15 to move the placement frame 7 upward. The one-way gear 17 on the outside of the rotating rod 15 rotates and moves upward along the outside of the one-way rack 18, causing the one-way gear 17 to drive the rotating rod 15 to rotate half a turn, realizing the flipping of the keyboard inside the placement frame 7. At the same time, the rotating rod 15 pulls the top of the two folding rods 24 to swing upward, causing the folding point of the folding rods 24 to drive the sleeve block 27 to move horizontally along the outside of the slide rod 28, and the bottom of the two folding rods 24... Pushing the push rod 25 downwards along the outside of the positioning frame 30, both push rods 25 push the bracket 9 away from the placement frame 7 through the corresponding mounting plate 26. Then, the electric telescopic rod 16 pulls the rotating rod 15 downwards to reset. Using the cooperation of the one-way gear 17 and the one-way rack 18, the keyboard is reset horizontally downwards. At the same time, the two folding rods 24 pull the push rod 25 upwards to reset, so that the multiple contact rods 31 on the top of the bracket 9 contact the top surface of the keyboard, providing horizontal support for the keyboard. Finally, the electric screwdriver 4 assembles the screws in the mounting slots on the bottom of the keyboard, thus completing the double-sided screw assembly of the keyboard and improving the screw assembly efficiency of the keyboard.
