[0062] The embodiments of this utility model will be described in detail below.

[0063] Example 1

[0064] An embodiment of this utility model discloses a keyboard riveting device:

[0065] Figure 1 This is a schematic diagram of the keyboard riveting device. As can be seen from the diagram, the device mainly consists of the following three parts:

[0066] Cabinet 1 provides an installation structure and space for other components in this embodiment. Additionally, a support frame 11 is provided on cabinet 1.

[0067] Assembly component 2 is mounted on support frame 11. Assembly component 2 is mainly used for pressing rivets.

[0068] The adjustment component 3 is mounted on the cabinet 1. The adjustment component 3 can adjust the keyboard 4 above it to facilitate the pressing of the rivets by the assembly component 2.

[0069] Overall, after the positioning component 3 adjusts the position of the keyboard 4, the assembly component 2 then presses in the rivets for riveting.

[0070] Detailed analysis, Figure 2This is an axial view of assembly component 2. As can be seen from the figure, assembly component 2 mainly includes a base 21, a lifting mechanism 22, a pressure sensor 23, a rivet 24, and an optical sensor 25, as detailed below:

[0071] The base 21 is mounted on the support frame 11. The base 21 is provided with a limiting protrusion 211 that serves as a guide.

[0072] A lifting mechanism 22 is mounted on a base 21. The lifting mechanism 22 includes a driving member 221, a transmission member 222, and a driven member 223. The driving member 221 is a motor capable of controlling the rotation angle, such as a servo motor. The transmission member 222 is a threaded lead screw, with its upper end connected to the working shaft of the driving member 221 and its other end connected to the driven member 223. The driven member 223 has a threaded hole that allows the lower end of the transmission member 222 to be screwed into it. Furthermore, the driven member 223 has a limiting recess 2231 on the side facing the limiting protrusion 211, which is slidably connected to the limiting protrusion 211. The limiting protrusion 211 and the limiting recess 2231 cooperate to form a guide structure, restricting the rotation of the driven member 223. In this way, when the driving component 221 rotates, the transmission component 222 rotates synchronously. The transmission component 222 is then connected to the driven component 223 through a lead screw pair, ultimately controlling the linear movement of the driven component 223.

[0073] One of the force-bearing surfaces of the pressure sensor 23 is attached to the underside of the follower 223. The pressure sensor 23 can periodically monitor the pressure it receives and feed the monitoring results back to the computer.

[0074] The press-fit component 24 is disposed on another force-bearing surface of the pressure sensor 23. The press-fit component 24 is a component used to contact and press the rivet.

[0075] In this way, the pressure between the rivet 24 and the rivet is transmitted to the pressure sensor 23. Therefore, the pressure sensor 23 monitors the force applied to the rivet.

[0076] Overall, by controlling the rotation angle of the drive component 221, the descent or ascent of the driven component 223 can be controlled, and ultimately the force with which the pressing component 24 presses the rivet can be controlled.

[0077] Specifically, the rotation direction of the drive component 221 is controlled to bring the pressing component 24 closer to and press the rivet; when the monitoring result of the pressure sensor 23 enters the predetermined range, the drive component 221 is controlled to rotate in the opposite direction, causing the pressing component 24 to move away from and release the rivet. Therefore, this invention can, to a certain extent, avoid damage to the motherboard while ensuring the riveting effect.

[0078] Assembly component 2 also includes an optical sensor 25, which may be an image sensor. It transmits captured image information to a processor, which may be a computer, to identify the position of the marker relative to the rivet 24. In this embodiment, the marker is a rivet on the keyboard.

[0079] In addition, to facilitate the pressing of rivets at different positions by assembly component 2, this embodiment also includes a positioning component 3 for adjusting the keyboard position, such as... Figures 3-5 As shown.

[0080] As shown in the figure, the adjustment component 3 mainly includes a first adjustment mechanism 31 and a second adjustment mechanism 32. Details are as follows:

[0081] The first adjustment mechanism 31 includes: a first carrying plate 311 disposed on the cabinet 1, a first slide rail 312 disposed on the first carrying plate 311, and a first slider 313 slidably connected to the first slide rail 312. The first adjustment mechanism 31 also includes a first motor 314, the working shaft of the first motor 314 being connected to a first lead screw 315.

[0082] The second adjustment mechanism 32 includes: a second carrier plate 321 disposed on the first slider 312, a second slide rail 322 disposed on the second carrier plate 321, and a second slider 323 slidably connected to the second slide rail 322. A second motor 324 is also provided to drive the second slider 323. The second motor 324 is connected to the second slider 323 via a second lead screw 325. When the second motor 324 rotates, the second lead screw 325 causes the second slider 323 to translate via a lead screw pair.

[0083] Furthermore, in order for the first adjusting mechanism 31 to drive the second adjusting mechanism 32, the first lead screw 315 at the working shaft end of the first motor 314 of the first adjusting mechanism 31 is connected to the nut 316 below the second carrier plate 321 of the second adjusting mechanism 32 via a lead screw pair. Therefore, when the first motor 314 rotates, the first lead screw 315 causes the nut 316 to translate via the lead screw pair, thereby driving the second adjusting mechanism 32 to translate.

[0084] The non-parallel design of the first slide rail 312 and the second slide rail 322 enables rivet positioning at any position within a two-dimensional plane. In this embodiment, the first slide rail 312 and the second slide rail 322 are perpendicular to each other to facilitate quick adjustment of the relative positions of the first slider 312 and the second slider 323.

[0085] In addition, a platform 33 is provided on the second slider 323 of the second adjustment mechanism 32, on which the keyboard 4 to be riveted can be placed.

[0086] Therefore, by simply controlling the rotation direction of the first motor 314 and the second motor 324, the position of the keyboard 4 can be adjusted, thereby adjusting the position of the rivets on the keyboard 4 relative to the pressing member 24. In addition to adjusting the position of the keyboard 4 using the first motor 314 and the second motor 324, the position of the stage 33 can also be manually adjusted, thereby adjusting the position of the rivets on the keyboard 4 relative to the pressing member 24.

[0087] Overall, the optical sensor 25 installed on assembly component 2 monitors and identifies the position information of the rivets on the keyboard relative to the pressing member 24, thus obtaining the direction and distance of the rivets relative to the pressing member 24. This direction and distance are used to control the rotation direction and angle of the first motor 314 and the second motor 324, thereby adjusting the rivet to be below the pressing member 24. Ultimately, this achieves automated pressing and traversal of the planned riveting area of ​​the keyboard, improving the keyboard riveting efficiency to a certain extent.

[0088] Example 2

[0089] In this embodiment, the cabinet 1, the base 21 in the assembly assembly 2, the pressure sensor 23, the rivet 24, the optical sensor 25, and the adjustment assembly 3 are the same as in embodiment 1, except that:

[0090] A lifting mechanism 22 is mounted on a base 21. This lifting mechanism 22 includes a driving member 221, a transmission member 222, and a driven member 223. The driving member 221 is a linear actuator capable of controlling the direction of movement, such as a cylinder or hydraulic cylinder; in this embodiment, a cylinder is used. The transmission member 222 acts as an intermediate medium, allowing the driving member 221 to indirectly control the driven member 223. In this way, the driving member 221 can control the linear movement of the driven member 223. Furthermore, the driven member 223 has a limiting recess 2231 on the side facing the limiting protrusion 211, which is slidably connected to the limiting protrusion 211. The limiting protrusion 211 and the limiting recess 2231 cooperate to form a guiding structure. Therefore, the driven member 223 can achieve linear movement with a certain precision.

[0091] Overall, by controlling the direction of movement of the driving component 221, the descent or ascent of the driven component 223 can be controlled, and ultimately the force with which the pressing component 24 presses the rivet can be controlled.

[0092] Specifically, the driving component 221 is controlled to move in the opposite direction, causing the pressing component 24 to approach and press the rivet. When the monitoring result of the pressure sensor 23 enters a predetermined range, the driving component 221 is controlled to move in the opposite direction, causing the pressing component 24 to move away from and release the rivet. Therefore, this invention can, to a certain extent, avoid damage to the motherboard while ensuring the riveting effect.

[0093] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
