This device can automatically clamp the laptop keyboard frame and automatically cut off the excess material on the frame, improving the efficiency of material removal. Simultaneously, manufacturers can reduce labor costs and quickly detect whether the excess material in the laptop keyboard frame has been completely removed. If the excess material in the frame is not completely removed, the device can specifically identify which part of the frame has not been cleaned.

[0004] The objectives and effects of this invention are achieved by the following specific technical means:

[0005] A device for removing the sprue from a laptop keyboard frame includes a frame and a chassis, wherein the chassis is fixed above the frame;

[0006] The rack is equipped with a positioning component for positioning the laptop keyboard frame. The positioning component includes an upper positioning plate and a lower positioning plate, with the upper positioning plate located above the lower positioning plate.

[0007] The frame is equipped with multiple sets of cutting components, all of which are used to remove the slag from the rubber frame of a laptop keyboard.

[0042] Please see Figure 1-3 The embodiments of the present invention will be further described below;

[0043] A device for removing the sprue from a laptop keyboard frame includes a frame 11 and a chassis 12, wherein the chassis 12 is fixed above the frame 11;

[0044] The frame 11 is provided with a positioning component for positioning the keyboard frame of a laptop computer. The positioning component includes an upper positioning plate 31 and a lower positioning plate 41. The upper positioning plate 31 is located above the lower positioning plate 41. The lower surface of the upper positioning plate 31 has multiple positioning grooves 33. The upper surface of the lower positioning plate 41 is fixed with multiple positioning blocks 43 that match the multiple positioning grooves 33.

[0045] Two horizontally distributed electric guide rails 51 are fixed on the inner surface of the frame 11. A support base 71 is slidably connected between the two electric guide rails 51 via a slider. The lower positioning plate 41 is fixed on the support base 71.

[0046] The outer wall of the chassis 12 is fitted with a display screen 13 and multiple buttons 14 through slots.

[0047] The holes in the laptop keyboard frame match the positioning block 43. The motorized rail 51 and the display screen 13 are electrically connected to multiple buttons 14. The working time of the motorized rail 51 can be preset by the buttons 14.

[0048] like Figure 9 As shown, industry professionals in the field of plastic injection molding are well aware that the laptop keyboard frame produced by injection molding will have multiple sprues inside. These sprues are formed by the solidification of the molten plastic at the mold inlet. The sprues need to be removed from the laptop keyboard frame later to obtain the finished laptop keyboard frame.

[0049] The positioning operation for the laptop keyboard frame to be processed is as follows:

[0050] Figure 1-2 As shown, the staff can simultaneously start the two electric guide rails 51 by pressing button 14. The display screen 13 can show the running status of the electric guide rails 51 and the running time of the electric guide rails 51. The two electric guide rails 51 will drive the lower positioning plate 41 to move towards the outer end of the electric guide rails 51. When the lower positioning plate 41 moves to the outer end of the electric guide rails 51, the button 14 will cut off the power to stop the electric guide rails 51 from working. This operation is to facilitate the staff to place the laptop keyboard frame that needs to be processed on the lower positioning plate 41.

[0051] Move the laptop keyboard frame to be processed above the lower positioning plate 41, aligning the holes in the laptop keyboard frame with the multiple positioning blocks 43 on the lower positioning plate 41. Lowering the laptop keyboard frame allows the multiple positioning blocks 43 on the lower positioning plate 41 to be inserted into the holes in the laptop keyboard frame, thus positioning the laptop keyboard frame on the lower positioning plate 41. Pressing button 14 again restarts the two electric guide rails 51, moving the lower positioning plate 41 and the laptop keyboard frame to the inner end of the electric guide rails 51. When the lower positioning plate 41 moves to the inner end of the electric guide rails 51, button 14 will de-energize and shut down the electric guide rails 51, thus positioning the laptop keyboard frame for later processing of the laptop keyboard frame's material head.

[0052] A movable platform 22 is slidably connected to the frame 11 via multiple guide rods. Multiple steel columns 81 are fixed to the bottom of the movable platform 22. At least two spring shafts 32 are installed between the movable platform 22 and the upper positioning plate 31. An electric cylinder 21 is fixed inside the housing 12. The output end of the electric cylinder 21 passes through the bottom of the housing 12 and is fixed to the top center of the movable platform 22.

[0053] The operation of the automatic clamping laptop keyboard frame is as follows:

[0054] The electric cylinder 21 is electrically connected to the button 14. The working time of the electric cylinder 21 can be set by the button 14. The operator can start the electric cylinder 21 by pressing the button 14. The electric cylinder 21 will drive the moving table 22 to move down. The moving table 22 will drive the spring shaft 32 and the upper positioning plate 31 to move down together. In order to ensure that the moving table 22 can move smoothly, multiple guide rods are provided on the frame 11 to guide the moving table 22. As the lower positioning plate 41 moves down step by step, the positioning block 43 on the lower positioning plate 41 can accurately enter the matching positioning groove 33, thereby positioning the laptop keyboard frame between the upper positioning plate 31 and the lower positioning plate 41. When the moving table 22 continues to move down, it will compress the spring shaft 32. The spring shaft 32 has a downward elastic force on the upper positioning plate 31, which helps the upper positioning plate 31 to press the laptop keyboard frame tightly. The laptop keyboard frame can be automatically clamped before the laptop keyboard frame is removed from the feed head, making the processing operation of the laptop keyboard frame more convenient.

[0055] The frame 11 is equipped with multiple sets of cutting components, all of which are used to remove the slag from the rubber frame of the laptop keyboard. The cutting components include steel columns 81 and blades 82. The blades 82 are provided with four pieces and are respectively installed around the bottom edge of the steel column 81.

[0056] The upper positioning plate 31 has a plurality of vertically opened insertion holes 34 that correspond to a plurality of material heads on the laptop keyboard frame. The lower ends of the plurality of steel columns 81 are inserted into the plurality of insertion holes 34 respectively. The blade 82 is located in the corresponding insertion hole 34. The lower positioning plate 41 has a plurality of vertically opened discharge ports 42, and the adjacent discharge ports 42 and insertion holes 34 are the same size and shape.

[0057] A grinding disc 83 is fixed below the periphery of the steel column 81 by a slot, and the surface of the grinding disc 83 is flush with the surface of the steel column 81.

[0058] The procedure for removing excess material from the rubber frame of a laptop keyboard is as follows:

[0059] When the positioning block 43 is precisely embedded in the matching positioning groove 33, the blade 82 at the bottom of the steel column 81 is still located in the insertion hole 34. As the compression of the spring shaft 32 gradually increases, the moving stage 22 drives the cutting assembly to move downward, allowing the blade 82 at the bottom of the steel column 81 to pass through the insertion hole 34 and perform a cutting operation on the material inside the laptop keyboard frame. Immediately afterwards, the grinding disc 83 on the steel column 81 can grind the cut area of ​​the laptop keyboard frame, making the cut area smoother. Figure 10As shown, the finished laptop keyboard frame is obtained. When the spring shaft 32 is compressed to its maximum extent, the electric cylinder 21 moves down to its maximum extent. Then, the electric cylinder 21 will drive the moving stage 22, the spring shaft 32, the upper positioning plate 31 and the cutting component to move up, so that the cutting component moves away from the laptop keyboard frame. When the moving stage 22 moves to the initial position, the button 14 will disconnect the power of the electric cylinder 21. This device can automatically cut the material head on the laptop keyboard frame, which improves the material head processing efficiency on the laptop keyboard frame, and at the same time, the manufacturer can reduce the input of personnel costs.

[0060] The outer wall of the support base 71 has a transversely penetrating mounting groove 72, the upper end of the mounting groove 72 penetrates the upper surface of the support base 71, and a conveyor belt 91 is installed in the mounting groove 72.

[0061] The rack 11 is equipped with a detection component for detecting the material head on the rubber frame of a laptop keyboard. The detection component includes a camera 61, an LED light 63, and an operation module.

[0062] The operation module is electrically connected to the conveyor belt 91. The operation module can preset the working and intermittent times of the conveyor belt 91. Before using the equipment, the garbage bin for collecting the material head can be placed behind the conveyor belt 91 for later collection.

[0063] The material discharge operation is as follows:

[0064] When the spring shaft 32 is compressed to its maximum extent, the cutting operation is completed. The cut material head will fall into the discharge port 42 due to gravity. Then the material head will pass through the discharge port 42 and fall onto the conveyor belt 91. At this time, the operation module will start the conveyor belt 91, and the conveyor belt 91 will transport the material head to the garbage bin to realize the material head discharge operation.

[0065] The LED lights 63 are provided in multiple units and are all located below the camera 61. The operation module is located inside the chassis 12. An electric lifting rod 62 is fixed in the middle of the bottom of the moving platform 22. The lower end of the electric lifting rod 62 is fixedly connected to the upper end of the camera 61. The upper positioning plate 31 has through holes 35 that are staggered from the insertion hole 34. The camera 61 is located in the through hole 35. The multiple LED lights 63 are installed on the lower surface of the conveyor belt 91. The discharge port 42, insertion hole 34 and LED lights 63 that are close to each other are located on the same vertical line.

[0066] The camera 61, electric lifting rod 62, and multiple LED lights 63 are all electrically connected to the operation module and multiple buttons 14. The operation module allows for preset working times for the camera 61, electric lifting rod 62, and multiple LED lights 63. The camera 61 can be used to take a picture in advance. Figure 10The image shown is of a clean laptop keyboard frame after the sprue has been removed. This image is then transmitted over the network to the operation module, providing a basis for the device to detect whether the sprue in the laptop keyboard frame has been completely removed.

[0067] The procedure for checking whether the excess material in the rubber frame of a laptop keyboard has been completely removed is as follows:

[0068] After conveyor belt 91 transfers all the material head into the waste bin, it runs half a revolution. Then, conveyor belt 91 continues to run. When conveyor belt 91 completes one revolution, the adjacent discharge ports 42, insertion holes 34, and LED lights 63 are aligned vertically. Next, the operation module activates the electric lifting rod 62 and multiple LED lights 63. The LED lights 63 illuminate the discharge port 42 and the area containing the material head within the laptop keyboard frame. The electric lifting rod 62 moves the camera 61 downwards, positioning it below the through hole 35 and below the upper positioning plate 31. This allows the camera 61 to photograph the laptop keyboard frame. At this point, the operation module deactivates the electric lifting rod 62 and activates the camera 61 to photograph the laptop keyboard frame. The photograph taken by the camera 61 is transmitted to the operation module via the network. The module then transmits the photo information to the display screen 13 via the network. The staff can clearly observe the photo on the display screen 13. When the information obtained by the operation module does not match the pre-taken photo, it means that the material residue in the newly processed laptop keyboard frame has not been completely removed. The operation module can specifically detect which part of the laptop keyboard frame has not been completely removed through electrical signals. After detection, the operation module will turn off the LED light 63 in the area where the material residue in the laptop keyboard frame has been completely removed, while the LED light 63 in the area where the material residue in the laptop keyboard frame has not been completely removed will continue to work. This allows the staff to immediately know which part of the laptop keyboard frame has not been cleaned. At the same time, it allows the staff to know that the blade 82 corresponding to the lit LED light 63 has become dull, so that the staff can replace the blade in time.

[0069] Conversely, when the information obtained by the operation module matches the pre-taken photo, it indicates that the excess material inside the newly processed laptop keyboard frame has been completely removed. The operation module will then turn off the camera 61 and all LED lights 63, and simultaneously activate the electric lifting rod 62 to move the camera 61 upward. When the camera 61 reaches its initial position, the operation module will turn off the electric lifting rod 62. Afterward, the two electric guide rails 51 will restart, causing the lower positioning plate 41 to move towards the outer end of the electric guide rails 51, making it easier for staff to remove the processed laptop keyboard frame.

[0070] In summary, with the use of camera 61, electric lifting rod 62, LED light 63 and operation module, it is possible to quickly detect whether the slag in the rubber frame of a laptop keyboard has been completely removed.

[0071] The following are the procedures for sourcing the finished laptop keyboard frame:

[0072] By pressing button 14, both electric guide rails 51 are activated simultaneously. The two electric guide rails 51 will drive the lower positioning plate 41 and the finished laptop keyboard frame to move towards the outer end of the electric guide rails 51. When the lower positioning plate 41 moves to the outer end of the electric guide rails 51, button 14 will cut off the power, causing the electric guide rails 51 to stop working. The staff can then remove the finished laptop keyboard frame from the lower positioning plate 41.
