Description

Technical Field

[0001] This utility model belongs to the technical field of automated equipment, and in particular relates to a keyboard torsion spring assembly mechanism. Background Technology

[0002] A torsion spring is a mechanical component that provides elastic force through torsional deformation. It is crucial in scenarios requiring rotational force feedback or reset functions (such as keyboards). In traditional manufacturing processes, due to the generally small size of electronic devices (including keyboards), the torsion spring's position needs to be precisely adjusted to ensure it fits within the mounting area. Therefore, in common production lines, torsion spring installation is typically done manually. However, the skill level and experience of installers vary, leading to fluctuations in assembly quality. For example, when installing torsion springs on the large keys of a keyboard, different workers may apply different torsional angles, affecting the key feel and lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a keyboard torsion spring assembly mechanism to address the technical deficiencies described in the background section.

[0004] The keyboard torsion spring assembly mechanism includes a horizontal moving module, which drives a horizontal moving frame. A vertical moving module is mounted on the horizontal moving frame, which drives a vertical moving frame. A lifting module is mounted on the vertical moving frame, which drives a lifting frame. The lifting module is equipped with a clamp.

[0005] The transverse module drives the transverse frame to move and the longitudinal module drives the longitudinal frame to move, thereby moving the fixture to the picking area and then to the mounting area to remove the torsion spring from the picking area and place it on the mounting area. During this process, the transverse module drives the transverse frame to move and / or the longitudinal module drives the longitudinal frame to move, thereby moving the fixture to move and causing the torsion spring to slide into or engage in the mounting area.

[0006] Based on the above technical solution, the present invention achieves the following beneficial effects:

[0007] 1. The horizontal moving frame is driven to move back and forth laterally by the moving module, the vertical moving frame is driven to move back and forth longitudinally by the vertical moving module, and the lifting frame is driven to move up and down by the lifting module, so as to move the fixture to the picking area to pick up the torsion spring and then transfer it to the installation area for placement. During the placement of the torsion spring in the installation area, the horizontal moving module drives the horizontal moving frame to move and / or the vertical moving module drives the vertical moving frame to move, thereby moving the fixture to move. By moving the torsion spring, the position of the torsion spring is precisely adjusted, and finally the torsion spring is moved to slide into or be locked into the installation area.

[0008] 2. Compared with the traditional manual installation of torsion springs, this utility model completes the installation of torsion springs through the mechanical structure, which can ensure the installation quality every time. In addition, it has significant advantages in terms of efficiency, precision, cost control and production stability, and is especially suitable for large-scale, high-precision or high-risk production scenarios.

[0009] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0010] In some embodiments, the lifting frame is equipped with a rotating module, the rotating module drives the rotating frame, and the clamp is mounted on the rotating frame;

[0011] Based on the aforementioned technical solution, during the placement of the torsion spring in the installation area, the rotating frame can be selectively driven by the rotating module to rotate the torsion spring held by the clamp, thereby adjusting the angle of the torsion spring.

[0012] In some embodiments, the mounting area is provided with a fixing groove for placing the torsion spring, and the periphery of the fixing groove is provided with an inclined guide surface to guide the torsion spring to slide in.

[0013] Based on the aforementioned technical solution, the following beneficial effects can be further achieved:

[0014] 1. During the process of the clamp moving the torsion spring it holds into the fixed groove, the inclined guide surface can guide the torsion spring to slide accurately into the fixed groove, thereby further improving the accuracy of placing the torsion spring.

[0015] 2. After the clamp holds the torsion spring and moves it above the installation area, the clamp can be released to allow the torsion spring to fall into the fixed groove by its own weight. During this process, the inclined guide surface can adjust the position of the torsion spring as it falls, so that the torsion spring can slide into the installation area, thereby improving the installation efficiency of the torsion spring.

[0016] In some embodiments, a first push spring is installed on the rotating frame, and the first push spring pushes a first push rod so that the lifting frame is driven to rise and fall by the lifting module, thereby driving the first push rod to push the torsion spring into the depth of the fixed groove.

[0017] Therefore, based on the above technical solution, the installation failure caused by the torsion spring failing to reach the depth of the fixing groove due to friction between the torsion spring and the inner wall of the fixing groove can be avoided.

[0018] In some embodiments, the side of the fixing groove is provided with a locking position for contacting the torsion arm of the torsion spring. The upper end of the locking position is provided with an inclined sliding surface so that the torsion arm can pass over the locking position and lock into the locking position by means of the sliding surface.

[0019] Based on the aforementioned technical solution, after the first push rod pushes the torsion spring deep into the fixing groove, the torsion arm of the torsion spring can be pushed past the locking position and locked into the locking position, thereby fixing the torsion spring in the fixing groove, that is, completing the installation of the torsion spring in the installation area.

[0020] In some embodiments, a second push spring is installed on the rotating frame, and the second push spring pushes a second push rod so that after the first push rod pushes the torsion spring into the depth of the fixing groove, the torsion spring blocks the first push rod from descending. At this time, the second push rod pushes the torsion arm of the torsion spring past the locking position and locks it in the locking position.

[0021] Based on the aforementioned technical solution, after the first push rod pushes the torsion spring deep into the fixing groove, the torsion arm can be locked into the locking position by a mechanical mechanism. This avoids the impact on key feel and lifespan caused by different torsion angles applied by different workers when installing the torsion spring on the keyboard.

[0022] In some implementations, the longitudinal shifting frame is equipped with an industrial camera for visual positioning;

[0023] Based on the aforementioned technical solution, the installation area, fixtures, and torsion springs are visually positioned using an industrial camera, thereby enabling more precise and stable adjustment of the torsion spring position during installation. Attached Figure Description

The transverse module 1 drives a transverse frame 11, and the transverse module 1 can be selected from modules such as lead screw modules or belt modules that can drive the transverse frame 11 to move laterally. A longitudinal module 12 is mounted on the transverse frame 11, and the longitudinal module 12 drives a longitudinal frame 13, and the longitudinal module 12 can be selected from modules such as lead screw modules or belt modules that can drive the longitudinal frame 13 to move longitudinally. A lifting module 14 and an industrial camera 18 are mounted on the longitudinal frame 13. The lifting module 14 drives a lifting frame 15, and the lifting module 14 can be selected from modules such as lead screw modules or belt modules that can drive the lifting frame 15 to move up and down. A rotating module 16 is mounted on the lifting frame 15, and the rotating module 16 drives a rotating frame 17, and the rotating module 16 can be selected from modules such as motors or rotary cylinders that can drive the rotating frame 17 to rotate.

[0035] A clamp 2 is mounted on the rotating frame 17. The clamp 2 is used to place the torsion spring 5 in the picking area 3 and to place the torsion spring 5 on the mounting area 4. The picking area 3 is the place where the torsion spring 5 to be installed is placed. The mounting area 4 is the place where the torsion spring 5 is to be installed, that is, the place in the keyboard where the torsion spring 5 needs to be installed. The mounting area 4 is provided with a fixing groove 41 for placing the torsion spring 5. The periphery of the fixing groove 41 is provided with an inclined guide surface 411 to guide the torsion spring 5 to slide in. The side of the fixing groove 41 is provided with a locking position 42. The locking position 42 is used to contact the torsion arm 51 of the torsion spring 5. The upper end of the locking position 42 is provided with an inclined sliding surface 421 so that the torsion arm 51 can pass over the locking position 42 and lock into the locking position 42 by means of the sliding surface 421.

[0036] A first push spring 21 and a second push spring 23 are installed on the rotating frame 17. The first push spring 21 pushes a first push rod 22; so that the lifting frame 15 is driven to rise and fall by the lifting module 14, thereby driving the first push rod 22 to push the torsion spring 5 into the depth of the fixing groove 41. The second push spring 23 pushes a second push rod 24, so that after the first push rod 22 pushes the torsion spring 5 into the depth of the fixing groove 41, the torsion spring 5 blocks the first push rod 22 from descending. At this time, the second push rod 24 pushes the torsion arm 51 of the torsion spring 5 past the locking position 42 and locks it in the locking position 42.

[0037] The longitudinal shift frame 13 is equipped with an industrial camera 18 for visual positioning.

[0038] The following is a description of the operation of a keyboard torsion spring assembly mechanism as described in this specific embodiment.

[0039] The transverse module 1 drives the transverse frame 11 to move, and the longitudinal module 12 drives the longitudinal frame 13 to move, thereby moving the clamp 2 to above the material handling area 3. Then, the lifting module 14 drives the lifting frame 15 to descend, causing the clamp 2 to descend to the side of the torsion spring 5 in the material handling area 3, where the clamp 2 grips the torsion spring 5. Afterward, the lifting module 14 drives the lifting frame 15 to reset. Then, the transverse module 1 drives the transverse frame 11 to move, causing the clamp 2 and the torsion spring 5 gripped by the clamp 2 to move above the mounting area 4. At this point, the transverse module 1 drives the transverse frame 11 to move, and / or the longitudinal module 12 drives the longitudinal frame 13 to move, causing the clamp 2 to shift, thereby finely adjusting the position of the torsion spring 5 by shifting it. Afterward, the clamp 2 releases its grip on the torsion spring 5, causing the torsion spring 5 to fall into the fixing groove 41, and the inclined guide surface 411 around the fixing groove 41... The torsion spring 5 is guided to slide precisely into the fixing groove 41. Then, the horizontal moving frame 11 is driven to move laterally back and forth by the moving module, and the vertical moving frame 13 is driven to move longitudinally back and forth by the vertical moving module 12, to adjust the positions of the first push rod 22 and the second push rod 24. Next, the lifting module 14 drives the lifting frame 15 to descend, causing the first push rod 22 to push the torsion spring 5 deep into the fixing groove 41. After the first push rod 22 pushes the torsion spring 5 deep into the fixing groove 41, the torsion spring 5 blocks the first push rod 22 from descending further. At this time, the second push rod 24 pushes the torsion arm 51 of the torsion spring 5 past the locking position 42 and locks it onto the locking position 42, finally completing the installation of the torsion spring 5 in the installation area 4. Afterward, the lifting module 14 drives the lifting frame 15 to rise and reset. At this time, the first push spring 21 pushes the first push rod 22 to reset, and the second push spring 23 pushes the second push rod 24 to reset.
