Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a mechanical keyboard board balancing pressure application device. Background Technology

[0002] Mechanical keyboard panels are mostly made of metal and serve as the keyboard casing. They have mounting holes corresponding to the key positions. They need to possess a certain level of strength and stability to ensure the overall stability of the keyboard structure. Furthermore, the smoothness of their surface affects the keyboard's user experience and aesthetic appearance.

[0003] Utility model patent CN206550157U discloses a mechanical keyboard flattening device. This device includes a frame, a mounting frame, a pressure roller assembly, a trimming fixture, and a drive unit. A worktable is located on top of the frame, the mounting frame is mounted on the worktable, the pressure roller assembly is mounted on the mounting frame, and the trimming fixture is positioned on the worktable, vertically opposite to the pressure roller assembly. The upper surface of the trimming fixture is arc-shaped, higher in the middle and lower on both sides. A metal plate is placed on the upper surface of the trimming fixture. The drive unit is mounted on the mounting frame and drives the pressure roller assembly downwards to roll it onto the mechanical keyboard. This utility model, by using an arc-shaped fixture with a convex center, avoids the problem of the metal plate rebounding after flattening, which leads to poor processing results, thus improving the flattening efficiency of the metal plate. Furthermore, it has a simple structure, is easy to operate, and is highly practical, making it significant for widespread application.

[0004] The mechanical keyboard board flattening device only uses a fixed pressure roller to flatten the mechanical keyboard board, without taking into account the elastic stress of the warped mechanical keyboard board, which is difficult to effectively eliminate stress. A single flattening is not enough to achieve the ideal flatness effect. In view of this, we propose a mechanical keyboard board balancing pressure application device. Utility Model Content

[0005] The purpose of this invention is to provide a mechanical keyboard board pressure balancing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mechanical keyboard pressure balancing device includes:

[0008] A preliminary leveling device is used to initially level a warped mechanical keyboard board. The preliminary leveling device includes a pair of vertically symmetrical fixed seats and several pressing components disposed on the fixed seats. The first end faces of the two fixed seats are facing each other. Seat plates are fixed at the left and right edges of the first end faces of the fixed seats. The pressing components are constrained between the two seat plates and slidably connected to the seat plates. Several springs are disposed between the seat plates and the pressing components. The pressing components include a movable seat and a pressing roller rotatably connected to the movable seat. A rotating motor is coaxially connected to the pressing roller.

[0009] The main body of the hydraulic leveling equipment uses the pressure of a hydraulic cylinder to further flatten the mechanical keyboard board that has been leveled by the preliminary leveling device. A discharge platform is located at the end of the worktable of the hydraulic leveling equipment near the end of the preliminary leveling device. Several grooves are formed between the top surface of the worktable of the preliminary leveling device and the top surface of the discharge platform. A first rotating column is rotatably connected to the first end of each groove, and a second rotating column is rotatably connected to the middle of each groove. A rotating rod is rotatably connected to the end of the hydraulic leveling equipment away from the preliminary leveling device. A conveyor motor is coaxially connected to the rotating rod. A conveyor belt is fitted around the first rotating column, the second rotating column, and the rotating rod. The conveyor belt is used to transport the mechanical keyboard board, which has been preliminarily leveled by the preliminary leveling device, to the worktable of the hydraulic leveling equipment.

[0010] Preferably, the top surface of the fixed seat is provided with a plurality of sleeve holes, and the bottom surface of the movable seat is provided with a plurality of sleeve cavities. The positions of the sleeve holes and the sleeve cavities correspond one-to-one, and the spring is sleeved between the sleeve holes and the sleeve cavities.

[0011] In this configuration, the sleeve hole and sleeve cavity position the spring, enabling the spring to stably provide elastic support for the movable seat, allowing the pressure-retaining component to adaptively adjust the pressure intensity according to the degree of keyboard board warping.

[0012] Preferably, the inner surface of the seat plate is provided with a plurality of vertical sliding grooves, and both the left and right ends of the movable seat are provided with protrusions, the outer ends of the protrusions extending into the sliding grooves;

[0013] In this configuration, the moving groove cooperates with the convex seat to guide and limit the sliding of the movable seat, ensuring that the pressing component moves stably in the vertical direction, so that the pressing roller can accurately act on the keyboard board.

[0014] Preferably, a protrusion is provided on the outer end face of the protrusion, and a stop block is provided at the top position of the sliding groove. The stop block is used to limit the position of the protrusion.

[0015] In this configuration, the stop block and the protrusion cooperate to prevent the movable seat from detaching from the seat plate when sliding, thus ensuring the safety and stability of the pressure component during operation.

[0016] Preferably, the pressure roller is disposed between the two protrusions and rotatably connected to the protrusions, and the rotating motor is fixed to the outer end of the protrusion;

[0017] In this setup, the boss provides a stable mounting structure for the pressure roller and the rotating motor, enabling the pressure roller to rotate stably under the drive of the rotating motor, and to evenly roll and flatten the keyboard board.

[0018] Preferably, a plurality of support rods are provided at the left and right ends of the two fixed seats, and the support rods are fixedly connected to the fixed seats;

[0019] In this configuration, the support rod enhances the structural stability of the fixing base, disperses the force exerted on the fixing base during operation, and prevents it from shaking or deforming.

[0020] Preferably, a feeding platform is provided at the front end of the preliminary leveling device. The feeding platform is fixedly connected to the fixed base located below. The mechanical keyboard board to be leveled can be delivered from the feeding platform to the two fixed bases.

[0021] In this setup, the feeding platform provides a position for the operator to place the keyboard, allowing the keyboard to enter the preliminary leveling device accurately and smoothly, thus improving operational convenience.

[0022] Preferably, the first rotating column and the second rotating column are on the same horizontal plane, the height of the rotating rod is lower than the height of the second rotating column, the outer end of the conveyor belt protrudes from the top surface of the discharge platform at the discharge platform position, and the conveyor belt is inclined downward toward the rotating rod in the main body of the hydraulic leveling equipment;

[0023] In this setup, the inclined design of the conveyor belt keeps the portion inside the hydraulic leveling equipment at a distance from the worktable. When the keyboard board is conveyed to the worktable, it will detach from the conveyor belt and remain inside the hydraulic leveling equipment, facilitating subsequent flattening.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This mechanical keyboard board balancing pressure application device uses a preliminary leveling device and multiple adaptive pressure components to initially level the warped mechanical keyboard board, allowing the mechanical keyboard board to release some of its elastic stress. Then, the main body of the hydraulic leveling equipment performs a secondary leveling process, which increases the flatness of the mechanical keyboard board through a step-by-step process.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1

[0037] Please see Figures 1-4The mechanical keyboard board balancing pressure application device includes a preliminary flattening device 100 for initially flattening a warped mechanical keyboard board. The preliminary flattening device 100 addresses the warping problem of the keyboard board in stages, and compared to direct flattening, it can better release the internal stress of the keyboard board, providing a good foundation for subsequent flattening processes. The preliminary flattening device 100 includes a pair of vertically symmetrically arranged fixing seats 110 and several pressing components 120 disposed on the fixing seats 110. The pressing assembly 120 includes a movable seat 121 and a pressing roller 122 rotatably connected to the movable seat 121. The pressing roller 122 is coaxially connected to a rotating motor 122a. The movable seat 121 can drive the pressing roller 122 to move, and the rotating motor 122a drives the pressing roller 122 to rotate. When the pressing roller 122 contacts the keyboard, it applies pressure to the keyboard by rolling. Under the rolling pressure of multiple pressing rollers 122, the deformed and warped mechanical keyboard is gradually corrected, reducing the damage to the keyboard surface caused by direct flat pressing.

[0038] like Figures 2-4 As shown, in this embodiment, the first end faces of the two fixed seats 110 are facing each other. Seat plates 111 are fixed to the left and right edges of the first end faces of the fixed seats 110. The pressing component 120 is constrained between the two seat plates 111 and slidably connected to the seat plates 111. The seat plates 111 further enhance the structural strength of the fixed seats 110 and provide a guiding structure for the sliding of the pressing component 120. Several vertical sliding grooves 111a are formed on the inner surface of the seat plates 111. Both ends of the movable seat 121 are provided with protrusions 121a. The outer ends of the protrusions 121a extend into the sliding grooves 111a. The sliding grooves 111a cooperate with the protrusions 121a to limit and guide the sliding of the movable seat 121, ensuring that the pressing component 120 slides stably in the vertical direction, thereby allowing the pressing roller 122 to accurately act on different positions of the keyboard board. A protrusion 121b is provided on the outer end face of the protrusion 121a, and a stop block 111b is provided at the top position in the sliding groove 111a. The stop block 111b is used to limit the protrusion 121b. The stop block 111b cooperates with the protrusion 121b to prevent the movable seat 121 from disengaging from the seat plate 111 during the sliding process, thus ensuring the safety and stability of the device operation.

[0039] like Figure 4 As shown, specifically, the pressure roller 122 is disposed between two protrusions 121a and is rotatably connected to the protrusions 121a. The rotating motor 122a is fixed at the outer end of the protrusion 121a. By starting the rotating motor 122a, the rotating motor 122a can drive the pressure roller 122 to rotate, so that under the action of friction, the mechanical keyboard board moves from the front end to the rear end of the preliminary leveling device 100.

[0040] like Figure 3 and Figure 4 As shown, further, a plurality of springs 110b are provided between the base plate 111 and the pressing component 120. The top surface of the fixed base 110 is provided with a plurality of sleeve holes 110a, and the bottom surface of the movable base 121 is provided with a plurality of sleeve cavities 121c. The positions of the sleeve holes 110a and the sleeve cavities 121c correspond one-to-one. The springs 110b are sleeved between the sleeve holes 110a and the sleeve cavities 121c. The setting of the springs 110b gives the pressing component 120 a certain elasticity, which can adaptively adjust the pressing pressure according to the degree of warping of the keyboard board. While ensuring effective flattening of the keyboard board, it avoids damage to the keyboard board due to excessive pressure.

[0041] like Figure 1 and Figure 2 As shown, in addition, several support rods 130 are provided at the left and right ends of the two fixed seats 110. The support rods 130 are fixedly connected to the fixed seats 110. The support rods 130 enhance the overall stability of the fixed seats 110, distribute the force on the fixed seats 110 during operation, and prevent them from shaking or deforming.

[0042] like Figure 1 and Figure 2 As shown, it is worth noting that a feeding platform 140 is provided at the front end of the preliminary leveling device 100. The feeding platform 140 is fixedly connected to the fixed base 110 located below. The mechanical keyboard board to be leveled can be delivered from the feeding platform 140 to the two fixed bases 110. The feeding platform 140 provides a convenient position for the operator to place the keyboard board, so that the keyboard board can enter the preliminary leveling device 100 accurately and stably, improving the convenience and efficiency of operation.

[0043] In this embodiment, the mechanical keyboard board balancing pressure application device first places the mechanical keyboard board to be flattened on the feeding platform 140; then, the keyboard board enters between the two fixed seats 110 from the feeding platform 140; next, the rotating motor 122a is started to drive the pressure roller 122 to rotate, and at the same time, the pressure assembly 120, under the action of the spring 110b, adaptively adjusts its position and pressure according to the warping of the keyboard board to perform preliminary flattening of the keyboard board; finally, the keyboard board that has completed preliminary flattening is ready for subsequent processing.

[0044] Example 2

[0045] To further flatten the mechanical keyboard board that has been preliminarily flattened by the initial flattening device 100, such as... Figure 1 , Figure 5 and Figure 6As shown, a hydraulic leveling equipment body 200 is provided after the preliminary leveling device 100. The hydraulic leveling equipment body 200 is equipped with a hydraulic cylinder and a pressure plate. After the hydraulic cylinder is started, the hydraulic cylinder drives the piston rod through the hydraulic oil pressure, which drives the pressure plate to press down, so as to stabilize the pressure and gradually flatten the keyboard board. The combination of the hydraulic cylinder and the pressure plate can provide stable and large pressure, so that the hydraulic leveling equipment body 200 uses the pressure of the hydraulic cylinder to flatten the mechanical keyboard board that has been leveled by the preliminary leveling device 100 again, making the mechanical keyboard board even flatter.

[0046] Specifically, a discharge platform 210 is provided at the end of the workbench of the hydraulic leveling equipment body 200 near the end of the preliminary leveling device 100. The discharge platform 210 is used to receive the keyboard board output from the preliminary leveling device 100 and provides a transition platform for the keyboard board to enter the hydraulic leveling equipment body 200.

[0047] In addition, several grooves 220 are provided between the top surface of the workbench of the preliminary leveling device 100 and the top surface of the discharge platform 210. A first rotating column 210a is rotatably connected at the first end of the groove 220, and a second rotating column 220a is rotatably connected at the middle of the groove 220. A pair of end plates are fixed at the end of the hydraulic leveling equipment body 200 away from the preliminary leveling device 100. A rotating rod 230 is rotatably connected between the two end plates. A conveyor motor 230a is coaxially connected to the rotating rod 230. A conveyor belt 240 is sleeved on the outside of the first rotating column 210a, the second rotating column 220a and the rotating rod 230. By starting the conveyor motor 230a, the conveyor motor 230a can drive the rotating rod 230 to rotate. Under the action of friction, the conveyor belt 240 moves on the outside of the first rotating column 210a, the second rotating column 220a and the rotating rod 230. The first rotating column 210a and the second rotating column 220a are on the same horizontal plane. The height of the rotating rod 230 is lower than that of the second rotating column 220a. The outer end of the conveyor belt 240 protrudes from the top surface of the discharge platform 210 at the discharge platform 210. When the mechanical keyboard board is discharged from the preliminary leveling device 100, the mechanical keyboard board will fall on the conveyor belt 240. Since the conveyor belt 240 is higher than the discharge platform 210, the mechanical keyboard board will fall on the conveyor belt 240, so that the conveyor belt 240 is used to transport the mechanical keyboard board that has been initially leveled by the preliminary leveling device 100 to the worktable of the hydraulic leveling equipment body 200.

[0048] Furthermore, the conveyor belt 240 is inclined downward toward the rotating rod 230 in the main body 200 of the hydraulic leveling equipment. Through the downward inclination design, part of the conveyor belt 240 is away from the worktable surface of the main body 200 of the hydraulic leveling equipment. This allows the mechanical keyboard board to separate from the conveyor belt 240 after being conveyed to the worktable of the main body 200 of the hydraulic leveling equipment, so that the mechanical keyboard board remains in the main body 200 of the hydraulic leveling equipment for easy flattening.

[0049] It is worth noting that the rotary motor 122a and the conveying motor 230a involved in this utility model are both existing conventional technologies, and will not be described in detail here.

[0050] In this embodiment, when the mechanical keyboard board balancing pressure application device is in use, the mechanical keyboard board, which has been initially leveled by the preliminary leveling device 100, is conveyed from the discharge platform 210 to the workbench of the hydraulic leveling equipment body 200 via the conveyor belt 240. By activating the hydraulic cylinder, the hydraulic cylinder drives the piston rod through the hydraulic oil pressure to push down the pressure plate, thereby flattening the keyboard board again. After flattening is completed, the processed keyboard board can be taken out.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
