[0001] This utility model belongs to the technical field of keyboard assembly equipment, specifically relating to a board-grabbing mechanism for gripping a keyboard substrate and a keyboard assembly mechanism. Background Technology
[0002] The keyboard's base plate is located inside the keyboard. Because it is relatively thin, it may be bent during transportation and handling. This unevenness can cause the holes on the base plate to misalign with the positioning posts on the keyboard base plate when it is installed inside the keyboard, requiring reinstallation or manual adjustment, which in turn affects assembly efficiency.
[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation
[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0026] like Figure 1-3 As shown, the board-removing mechanism 100 in one embodiment of this utility model includes a mounting bracket 10, and a clamping component 20, a pressure plate 30, and a driving component 40 mounted on the mounting bracket 10. The pressure plate 30 is used to press and flatten the keyboard board to be assembled or transferred. Under the drive of the driving component 40, the clamping component 20 clamps the keyboard board after the pressure plate 30 presses it and installs it into the keyboard or transfers it to other subsequent steps.
[0027] Keyboard substrates are typically thin and can be bent during transport and handling due to impacts and compression. Because the substrate has holes, alignment with the screw holes or limit posts on the base plate is necessary during assembly. Therefore, bending can prevent the holes and screw holes / limit posts from being aligned during assembly, affecting subsequent assembly processes.
[0028] In practical use, the board-grabbing mechanism 100 descends to approach the keyboard substrate. Before gripping, the pressure plate 30 presses the keyboard substrate on the worktable to flatten it, and then the gripping assembly 20 grips it. Because the substrate is flattened, the holes on the keyboard substrate can be more accurately aligned with the mounting holes or limiting posts on the keyboard base plate during subsequent assembly. Alternatively, the pressure plate 30 can flatten the substrate on the keyboard base plate during subsequent assembly, reducing readjustment, shortening assembly time, and improving assembly efficiency.
[0029] In one embodiment, four pressure plates 30 are fixed on the mounting bracket 10, two of which are located at both ends along the length of the mounting bracket 10, and the remaining two are located on the same side of the mounting bracket 10. By providing a larger number of pressure plates 30, the number of contact points between the pressure plates and the keyboard substrate can be increased. When there are many bends or uneven areas on the keyboard substrate, it can be better pressed and flattened, which facilitates subsequent assembly.
[0030] In other embodiments, without interfering with the gripping assembly 20, the area of a single pressure plate 30 can be increased, or the number of pressure plates 30 can be increased, or both, to increase the total contact area with the keyboard substrate, so as to better compress and flatten the keyboard substrate.
[0031] Preferably, the pressure plate 30 can be made of a flexible material (such as rubber), giving it a certain degree of deformation. Compared to using a rigid material, the flexible pressure plate 30 can avoid scratching the surface when contacting the keyboard substrate. By using a flexible material, the bottom surface of the pressure plate 30 can extend below the gripper 22, allowing it to contact the keyboard substrate first as it descends with the board-taking mechanism 100, and then deform as it continues to descend, squeezing and flattening the keyboard substrate.
[0032] In other embodiments, a retractable buffer rod 31 (such as an oil spring rod, a pneumatic rod, etc.) can be provided between the pressure plate 30 and the mounting bracket 10. In this case, the height of the pressure plate 30 can be set lower, so that the contact time between the pressure plate 30 and the keyboard substrate is longer when the pressure plate 30 moves down with the board taking mechanism 100, and the resulting extrusion pressure changes more linearly, thereby improving the flattening effect on the keyboard substrate.
[0033] In one embodiment, a plurality of first elongated holes 121 are provided on the substrate 10, and the pressure plate 30 is mounted on the first elongated holes 121 through the connecting arm 11. Therefore, the positions of the connecting arm 11 and the pressure plate 30 are adjustable. When clamping keyboard substrates of different shapes, the position of the pressure plate 30 can be adjusted to adapt to the new shape, which provides high flexibility.
[0034] Clamping component 20 Figure 2As shown, the assembly includes two opposing clamping plates 21 and multiple grippers 22 fixed to the clamping plates 21. The drive assembly 40 includes gripping cylinders fixed to the mounting bracket 10, used to drive the clamping plates 21 closer together or further apart. For example, two gripping cylinders can be provided on the mounting bracket 10, respectively connected to and driving the movement of the two clamping plates 21.
[0035] After the pressure plate 30 presses the keyboard substrate, the clamping cylinder drives the two clamping plates 21 to move closer together to clamp the keyboard substrate. After moving to the predetermined position of the next station, the clamping cylinder reverses to drive the two clamping plates 21 to move away from each other, thereby releasing the keyboard substrate.
[0036] In other embodiments, one clamping plate 21 can be fixed to the mounting bracket 10 and cannot move, while the other clamping plate 21 can be moved by a clamping cylinder. This arrangement reduces the number of cylinders and moving mechanisms, simplifying the overall structure.
[0037] like Figure 2 As shown, a second elongated hole 211 is also provided on the clamping plate 21, which almost covers the entire clamping plate 21 along its length. The clamping claw 22 is installed in the second elongated hole 211, so the position of the clamping claw 22 is adjustable. When transferring or assembling keyboard substrates of different shapes, the position of the clamping claw 22 can be adjusted for adaptation, which is highly flexible.
[0038] Gripper 22 Figure 3 As shown, the gripper includes a fixing portion 221 mounted to the clamping plate 21, and a claw portion 222 extending from the fixing portion 221. The claw portion 222 includes a tip 2221 at the end away from the fixing portion 221, and a slope 2222 connecting the tip 2221 and the fixing portion 221. Because the keyboard substrate is thin, the tip 2221 is made thinner, allowing the claw 22 to more easily enter under the keyboard substrate. As the clamping plates 21 approach each other, the keyboard substrate moves upward a certain distance along the inclined slope 2222 and is supported on the claw portion 222. Therefore, the design of the claw 22 makes it easier to grip the keyboard substrate without squeezing it during the gripping process, and even avoids the situation where the thick tip of the claw 22 squeezes the keyboard substrate, causing secondary deformation.
[0039] Preferably, a guide module is further provided between the mounting bracket 10 and the clamping plate 21, including a positioning block 13 fixed on the mounting bracket 10 and a guide post 212 fixed on the clamping plate 21. The positioning block 13 has a positioning hole for the guide post 212 to pass through. The guide post 212 passes through the positioning hole and moves axially along the positioning hole. The axial direction of the guide post 212 and the positioning hole is parallel to the output direction of the clamping cylinder, which helps to fix the posture of the clamping plate 21 and avoid the clamping plate 21 from tilting or shifting.
[0040] In another embodiment, the gripping component 20 can be omitted, and the keyboard substrate can be moved by adsorption through the pressure plate 30. Specifically, the gripping component 20 structure is removed from the mounting bracket 10, and the pressure plate 30 is made axially hollow. When the pressure plate 30 moves down with the mounting bracket 10 and flattens the keyboard substrate, a negative pressure environment is created between the pressure plate 30 and the keyboard substrate by an external negative pressure device. Since the keyboard substrate itself is relatively light, it can be lifted by creating a normal negative pressure environment.
[0041] Since the clamping component 20 is eliminated and only the pressure plate 30 is retained, the plate-removing mechanism in this embodiment is simpler, and the pressure plate 30 can be connected to an external negative pressure device.
[0042] like Figure 2 As shown, in one embodiment, the mounting bracket 10 has a two-layer structure, including a first substrate 11 below and a second substrate 12 above the first substrate 11. A clamping cylinder is disposed between the first substrate 11 and the second substrate 12. A clamping component 20 is fixed on the first substrate 11, and a first elongated hole 121 is formed on the second substrate 12.
[0043] like Figure 4-6 As shown, this utility model also provides a keyboard assembly mechanism 200, which, in addition to the aforementioned board-removing mechanism 100, includes a main support 50 and a displacement mechanism 60. The main support 50 is provided with a platform 51 for preventing the keyboard board from moving. The displacement mechanism 60 includes a guide rail 61, a slider 62, a stepper motor 63, and a drive cylinder 64. The guide rail 61 is fixed on the main support 50, the slider 62 is supported on the guide rail 61, and is driven by the stepper motor 63 fixed on the main support 50 to move on the guide rail 61. The board-removing mechanism 100 is mounted on the slider 62 and is driven by the drive cylinder 64, which is also fixed on the slider 62, to achieve vertical movement.
[0044] In actual operation, the drive cylinder 64 drives the board-grabbing mechanism 100 downward and close to the table surface 51. The board-grabbing mechanism 100 clamps (or adsorbs) the keyboard board placed on the table surface 51. Then, the drive cylinder 64 reverses to drive the board-grabbing mechanism 100 upward. Driven by the stepper motor 63, the board-grabbing mechanism 100 moves to the other side of the main support 50. This side can be, for example, […]. Figure 4 The standard work surface shown is used for manual inspection and assembly by workers. Alternatively, other automated equipment, such as other assembly mechanisms, can be used to achieve fully automated keyboard assembly, further improving assembly efficiency.
