[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Reference Figures 1 to 6 As shown, this utility model provides an automatic transfer and loading device for a keyboard frame. In one embodiment, it includes a keyboard transmission line 1 and a keyboard transfer mechanism 2. The keyboard transfer mechanism 2 includes a keyboard sliding base plate 21, a keyboard Z-axis mechanism 22, and a keyboard lifting frame 23 connected to the keyboard Z-axis mechanism 22. Each end of the top of the keyboard lifting frame 23 is connected to a keyboard connecting vertical frame 24, and a keyboard Y-axis mechanism 25 is installed on the top of one keyboard connecting vertical frame 24, while a first slide rail module is installed on the top of the other keyboard connecting vertical frame 24. One end of the keyboard sliding base plate 21 is slidably arranged on the first slide rail module, and the other end of the keyboard sliding base plate 21 is connected to the keyboard Y-axis mechanism 25. A keyboard transfer module 26 is installed at the bottom of the keyboard sliding base plate 21. The keyboard transmission line 1 passes through the two keyboard connecting vertical frames 24 and is located below the keyboard transfer module 26. A keyboard lifting mechanism 11 and a keyboard stopping mechanism 12 are also installed on the keyboard transmission line 1.

[0015] In this embodiment, the keyboard transmission line 1 is used to transport the keyboard frame, and the keyboard transfer mechanism 2 is responsible for transferring the keyboard frame from the transmission line to the assembly position. Specifically, the keyboard sliding base plate 21 can move along the Y-axis direction under the drive of the keyboard Y-axis mechanism 25, while the keyboard Z-axis mechanism 22 can drive the keyboard lifting frame 23 to rise and fall along the Z-axis direction, thereby driving the keyboard connecting vertical frame 24 and the keyboard Y-axis mechanism 25 installed on it to rise and fall, realizing positioning in the Z-axis direction. Through the cooperation of the two (the keyboard Y-axis mechanism 25 and the keyboard Z-axis mechanism 22 can be existing linear modules), the keyboard transfer module 26 can be driven to perform translation and lifting movements, thereby facilitating the transfer of the keyboard frame. At the same time, the keyboard transmission line 1 is also equipped with a keyboard lifting mechanism 11 and a keyboard stopping mechanism 12. The keyboard stopping mechanism 12 is used to stop the keyboard frame, while the keyboard lifting mechanism 11 is used to lift the keyboard frame from the conveyor belt so that the keyboard transfer module 26 can transfer the keyboard frame.

[0016] In a preferred embodiment, the keyboard transfer module 26 includes a first suction plate 261 mounted on the bottom of the keyboard sliding base plate 21, a second suction plate 262 mounted on the bottom of the first suction plate 261, and a first keyboard suction nozzle 263 mounted on the bottom of the second suction plate 262; the bottom of the first suction plate 261 is provided with adjustment mounting holes at both ends and one side of the second suction plate 262, and a contour key adjustment component 264 is also installed in the adjustment mounting holes. Figure 4 As shown, one end of the first suction plate 261 has three adjustment mounting holes, from bottom to top, for mounting the phasing key adjustment component 264 for the TAB key, the phasing key adjustment component 264 for the Caps Lock key, and the phasing key adjustment component 264 for the Shift key. The other end of the first suction plate 261 has four adjustment mounting holes, from bottom to top, for mounting the phasing key adjustment component 264 for the "←" key, the phasing key adjustment component 264 for the "\" key, the phasing key adjustment component 264 for the Enter key, and the phasing key adjustment component 264 for the Shift key. One side of the first suction plate 261 has an adjustment mounting hole for mounting the phasing key adjustment component 264 for the space bar.

[0017] Preferably, a bearing step 265 is provided on the inner wall of each end of the adjustment mounting hole; the contour key adjustment assembly 264 includes a contour key fixing block 2641, a contour key lifting block 2642, two lifting guide posts 2643, and a limiting horizontal plate 2644; each end of the contour key fixing block 2641 is installed on a bearing step 265, and each end of the contour key fixing block 2641 is also installed with a lifting guide sleeve; the two lifting guide posts 2643 are respectively arranged to move through a lifting guide sleeve; the top of the contour key lifting block 2642 is connected to the bottom of the two lifting guide posts 2643, limiting... The bottom of the horizontal plate 2644 is connected to the top of the two lifting guide columns 2643; the bottom of the contour key lifting block 2642 is also provided with a balance bar contour groove 2645; the outer wall of the lifting guide column 2643 is also fitted with a first spring 2646, and the two ends of the first spring 2646 are respectively in contact with the bottom of the contour key fixing block 2641 and the top of the contour key lifting block 2642; the contour key adjustment assembly 264 also includes a limiting screw 2647 installed vertically on the limiting horizontal plate 2644; the bottom of the contour key lifting block 2642 is also equipped with a second keyboard suction nozzle 2648.

[0018] The keyboard transmission line 1 connects to the upstream balance bar assembly machine. After the balance bar assembly machine assembles the balance bar to the corresponding position on the keyboard frame, it is then transmitted to the keyboard transmission line 1. The bottom of the key-lifting block 2642 is also provided with a balance bar contouring groove 2645. After the keyboard transfer module 26 moves the keyboard frame to the assembly position, the key-lifting block 2642 descends under the drive of the keyboard Z-axis mechanism 22 to correct the position of the balance bar on the keyboard frame via the balance bar contouring groove 2645. This prevents the balance bar from shifting during the keyboard frame transfer process, which would affect the subsequent keycap assembly process. Specifically, in this embodiment, the lifting guide sleeve can guide the lifting guide post 2643. The function of the sliding base plate 21 is to allow the key lifting block 2642 to rise and fall smoothly. The bottom of the limiting screw 2647 on the limiting plate 2644 abuts against the top of the key fixing block 2641, which limits the descent stroke of the key lifting block 2642 and prevents it from falling. At the same time, a first spring 2646 is provided between the bottom of the key fixing block and the top of the key lifting block 2642, which can play a buffering role when the key lifting block 2642 is pressed down. In addition, a fine-tuning fixing block is connected to each end of the bottom of the keyboard sliding base plate 21, and an adjusting screw is installed on each fine-tuning fixing block. One end of each of the two adjusting screws contacts one end of the first suction plate 261. The left and right positions of the first suction plate 261 can be finely adjusted by the two adjusting screws to improve the accuracy of keyboard transfer.

[0019] In one embodiment, a brush cleaning assembly 27 is also installed on one side of the keyboard sliding base plate 21. The brush cleaning assembly 27 includes a brush lifting cylinder 271 installed on one side of the keyboard sliding base plate 21, a brush lifting plate 272 connected to the brush lifting cylinder 271, and a cleaning brush 273 installed on one side of the brush lifting plate 272. Before the keyboard transfer module 26 transfers the keyboard frame to the assembly position, the assembly position can be cleaned by the cleaning brush 273 to avoid any parts residue and ensure that the keyboard frame is placed flat on the assembly position.

[0020] In one embodiment, the keyboard transmission line 1 includes two keyboard transmission racks 13; the two keyboard transmission racks 13 are arranged in parallel and spaced apart, and a keyboard transmission belt module is installed on each opposite side of the two keyboard transmission racks 13; each keyboard transmission rack 13 is also equipped with a first motor assembly for driving the keyboard transmission belt module to operate; a clearance slot 14 is opened at each of the top two ends of the keyboard transmission rack 13, and the part of the keyboard transmission belt module located in the clearance slot 14 is arranged below one side of the clearance slot 14.

[0021] The clearance slots 14 at both ends of the top of the keyboard transfer rack 13 provide space for subsequent lifting operations (the keyboard lifting mechanism is installed on the keyboard transfer mechanism, and its function is to lift the carrier carrying the keyboard frame from the conveyor belt module to a suitable height so that the keyboard transfer module 26 can smoothly grab the keyboard frame).

[0022] Preferably, each of the keyboard transmission racks 13 is connected to a lifting mounting plate 15 on its other side, and a keyboard lifting guide rail 16 is arranged vertically on one side of the lifting mounting plate 15; the keyboard lifting mechanism 11 includes a keyboard lifting support plate 111 and two keyboard lifting cylinders 112; the two keyboard lifting cylinders 112 are respectively installed on one side of a lifting mounting plate 15; the keyboard lifting support plate 111 has a rectangular hollow structure, and the bottom of both sides of the keyboard lifting support plate 111 is respectively connected to a keyboard lifting cylinder 112, and the two ends of the keyboard lifting support plate 111 are arranged through the clearance slot 14; the bottom sides of the keyboard lifting support plate 111 are also connected to lifting connecting plates 113, and the lifting connecting plates 113 are slidably arranged on the keyboard lifting guide rail 16.

[0023] The keyboard lifting tray 111 in the keyboard lifting mechanism has a rectangular hollow structure. Its bottom sides are connected to the keyboard lifting cylinders 112. The lifting and lowering movement of the keyboard lifting tray 111 is achieved through the extension and retraction of the cylinders. Both ends of the keyboard lifting tray 111 pass through the clearance slots 14 at the top of the keyboard transfer frame 13, providing space for the keyboard lifting tray 111 to move up and down. The lifting connecting plates 113 connected to the bottom sides of the keyboard lifting tray 111 are slidably arranged on the keyboard lifting guide rails 16. The guide rails ensure smoother and more precise lifting movement of the tray, preventing swaying or displacement during the lifting process and providing reliable protection for subsequent transfer operations. Simultaneously, carrier positioning pins are installed at both ends of the top of the keyboard lifting tray 111, enabling quick positioning of the carrier carrying the keyboard frame.

[0024] In one embodiment, the keyboard blocking mechanism 12 includes a blocking mounting base 121 connected to one side of one of the keyboard transmission racks 13, a cylinder guide seat 122 connected to one side of the blocking mounting base 121, and a first blocking cylinder 123 installed at the bottom of the cylinder guide seat 122. The top of the cylinder guide seat 122 has a blocking guide hole extending to its bottom. The output shaft of the first blocking cylinder 123 is also connected to a blocking telescopic block 124. The upper part of the blocking telescopic block 124 is movably arranged through the blocking guide hole, and a first blocking block 125 is connected to one side of the upper part of the blocking telescopic block 124. The first blocking cylinder 123 can drive the blocking telescopic block 124 to raise and lower the first blocking block 125, thereby blocking or releasing the vehicle. When the blocking telescopic block 124 is raised or lowered, the blocking guide hole can guide it.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
