Description

Technical Field

[0001] This utility model relates to the field of keyboard keycap adsorption assembly technology, and in particular to an adsorption robotic arm structure for keyboard keycap assembly. Background Technology

[0002] The suction-type robotic arm for keyboard keycap assembly is an automated device used in the keyboard production and assembly process. It picks up keycaps through a suction device and then installs them into the corresponding positions on the keyboard. It features accurate positioning, flexible operation, and can improve assembly efficiency and quality, effectively reducing labor costs and labor intensity.

[0003] The use of an adsorption-type robotic arm structure for keyboard keycap assembly is intended to automate keycap assembly, enabling precise gripping and placement of keycaps, improving assembly efficiency and quality, reducing human error, lowering labor costs, adapting to large-scale production needs, and enhancing enterprise competitiveness.

[0004] During keyboard keycap assembly, the single suction mechanism of an adsorption robotic arm has limited suction force, leading to keycaps easily falling off or unstable gripping, affecting assembly efficiency and stability. Existing technologies have addressed this by adding multiple suction mechanisms to distribute the suction force and increase overall suction force, effectively solving the problem of insufficient suction force from a single mechanism and ensuring stability during keycap gripping. However, in actual use, the frequent contact between multiple suction structures and the keycap surface, along with the significant pressure generated during keycap adsorption and placement, can easily leave indentations and scratches on the keycap surface, failing to effectively guarantee the keycap's appearance quality and increasing the defect rate.

[0022] 1.

The connecting rod realizes multi-angle movement in the vertical plane, and the joint expands the range of motion in the horizontal and vertical directions, so that the adsorbent can accurately reach the keycap gripping position. The extension and retraction of the hydraulic rod drives the adsorbent to approach the keycap and transport and place the keycap. The buffer ring on the front side of the adsorbent plays a buffering role during operation, avoiding damage such as pressure marks and scratches on the surface of the keycap, effectively ensuring the appearance quality of the keycap and effectively reducing the defect rate.

[0037] Specifically, rubber pads 13 are fixedly connected to the four corners of the bottom of the casing 1. The rubber pads 13 have a buffering effect, which can effectively reduce the impact of vibration generated during equipment operation on the ground, reduce equipment operating noise, and at the same time prevent the casing 1 from hard contacting the ground and causing wear. Supports 14 are fixedly connected to the bottom of the multiple rubber pads 13. The supports 14 increase the contact area with the ground, improve the stability of the equipment placement, prevent the equipment from tilting or tipping over, and ensure the safe operation of the equipment.

[0038] Reference Figure 1 , Figure 3 and Figure 5 Heat sinks 17 are fixedly connected to both the left and right sides of the housing 1. The heat sinks 17 are attached to the surface of the housing 1. Multiple heat sinks 18 are fixedly connected to the opposite side of the two heat sinks 17. The heat sinks 18 increase the contact surface with the air. The top of multiple bolts 205 is provided with hexagonal slots 21.

[0039] Specifically, heat sinks 17 are fixedly connected to both the left and right sides of the casing 1. The heat sinks 17 are in contact with the surface of the casing 1, and by being in contact with the casing 1, they quickly conduct heat generated inside the casing 1, providing a basis for subsequent heat dissipation. Multiple heat sinks 18 are fixedly connected to the opposite sides of the two heat sinks 17. The heat sinks 18 increase the contact area with the air, and by utilizing the increased surface area, they accelerate the heat exchange rate between the heat sink and the air, improving heat dissipation efficiency.

The ventilation slots 22 facilitate ventilation between the inside and outside of the housing 1, promote air circulation, and help reduce the internal temperature of the housing 1. The chamfering of the ventilation slots 22 prevents scratches to the operator and avoids the operator being cut by the edges of the ventilation slots 22 during equipment maintenance.

[0040] Working principle: During use, the motor 4, fixed to the top of the inner side of the housing 1, is activated. The output of motor 4 rotates, causing the robotic arm base 3, fixedly connected to its bottom, to rotate synchronously by a certain angle, thus adjusting the horizontal angle of the robotic arm. By controlling the coordinated movement of connecting rod 5, joint 6, connecting rod 7, and joint 8 connected to the top of the robotic arm base 3, the rotation of connecting rod 5 and connecting rod 7 enables multi-angle movement of the robotic arm in the vertical plane. The horizontal rotation of joint 6 and the vertical rotation of joint 8 further extend the range of motion of the robotic arm, allowing the suction device 1 to move at multiple angles. When the keycap is reached, the hydraulic rod 9 connected to the front of the control joint 8 rotates freely, extending and retracting, driving the suction device 10 to approach the keycap. The suction device 10 has an internal air tube that generates suction force through multiple suction cups 11, stably gripping the keycap. Through the coordinated movement of the motor 4, connecting rod 5, joint 6, connecting rod 7, joint 8 and hydraulic rod 9, the keycap is transported to the designated position and placed, completing the keycap assembly. The buffer ring 12 fixed on the front outer wall of the suction device 10 plays a buffering role during the suction and placement process, protecting the keycap from damage.

[0041] Furthermore, by threading the four bolts 205 on the top of the fixing blocks 202 on the left and right sides of the base 201 to the housing 1, and using the washers 206 to prevent the bolts 205 from damaging the fixing blocks 202, the base 201 is securely installed on the top of the housing 1, ensuring the overall stability of the infrared detection mechanism 2. The infrared detector 203 fixed to the top of the base 201 works continuously to detect whether there are personnel within the range of the robotic arm's movement in real time. When the machine is running, if the infrared detector 203 detects that there are personnel within the range of the robotic arm's swing, the indicator light 204 on its top front side will immediately light up, providing a direct visual signal to alert the operator and surrounding personnel and causing the machine to stop abruptly. Through the connection and fixation of the base 201, fixing blocks 202, bolts 205, and washers 206, as well as the coordinated work of the infrared detector 203 and indicator light 204, the monitoring and safety warning of personnel activities within the working area of ​​the robotic arm are achieved.
