Description

Technical Field

[0001] This utility model relates to the field of automation control technology and is mainly applied to robot inspection and maintenance scenarios in data centers or computer rooms. Specifically, it is a flexible touch head mechanism that can click on touch screens or digital instruments or press buttons or door handles. Background Technology

[0002] In server room and data center inspection scenarios, the operation and data reading of control panel screens on server racks, such as server status adjustment screens and equipment parameter setting screens, or independent digital instruments, such as ammeters, voltmeters, and temperature and humidity displays, are core aspects of the inspection work. Currently, the operation of these screens and instruments is still mainly manual: staff need to approach each device one by one among densely packed server racks, manually click on screen menus, trigger instrument function keys, or confirm data. This not only requires frequent bending over and reaching to adjust operating posture, but also increases the risk of click errors due to visual fatigue when facing a large number of devices, resulting in accidental touches of adjacent buttons. In addition, additional data recording is required, leading to low overall process efficiency. At the same time, some screens and instruments are installed in the middle or deep layers of the server racks, and manual operation may result in touching nearby live components, posing a risk of electric shock. Furthermore, the response delay problem of manual inspection is further highlighted at night or in unattended server rooms.

[0003] To address these issues, while existing intelligent inspection robots equipped with six-axis robotic arms attempt to cover screen and instrument operation scenarios, they suffer from significant shortcomings in their touch control structure design. Firstly, existing robots often use fixed-length touch components (such as rigid metal rods or fixed flexible heads), which cannot adapt to the varying installation depths of screens or digital instruments in different cabinets. When the screen is deeply embedded in the cabinet, the fixed-length components cannot reach it; when the screen is near the outside of the cabinet, excessively long components are prone to colliding with surrounding equipment due to the robot arm's inertia. Secondly, the touch force lacks precise control. Existing structures do not incorporate force control adjustment. When the robot arm moves the touch component to click the screen, excessive force can cause the screen glass to shatter or the instrument buttons to dent, while insufficient force will not trigger effective operation. Furthermore, with the intelligent upgrading of data center equipment, the types of screens and digital instruments are becoming increasingly diverse (such as capacitive screens, resistive screens, and small membrane keypad instruments). Existing touch structures cannot accommodate the needs of devices with different touch principles, further limiting the coverage of unmanned inspections.

[0004] In summary, the current field of data center inspection robots urgently needs a scalable, adaptable, and force-controlled touch pen head structure to solve the problems of low efficiency and poor safety of manual operation, as well as the weak adaptability and insufficient stability of existing automated touch structures.

[0030] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0031] This utility model provides a structural schematic diagram of an embodiment of a flexible touch head mechanism, including:

[0032] Please see Figures 1-4 This invention proposes a flexible touch head mechanism, which includes a force-controlled sliding cylinder 1, a positioning support 2, a positioning component 3, a guide connector 4, a contact connector 5, and a flexible contact 6. The force-controlled sliding cylinder 1 includes a control module 12 and a force control sensor (not shown in the figure). The force control sensor is electrically connected to the control module 12, and the entire force-controlled sliding cylinder 1 is electrically connected to an external power supply. Thus, the output stroke and thrust of the force-controlled sliding cylinder 1 can be set by the control module 12. When the force-controlled sliding cylinder 1 is working normally, its thrust output shaft 11 extends to reach the target stroke. If the thrust output shaft 11 receives a force feedback exceeding the set value, the motor of the force-controlled sliding cylinder 1 stops working in time, so that the thrust output shaft 11 stops displacing. If the force does not exceed the set value, it continues to work until the target stroke is reached.

[0033] The force-controlled slide cylinder 1 is installed on one side of the positioning support 2. The thrust output shaft 11 of the force-controlled slide cylinder 1 passes through to the other side of the positioning support 2. The positioning member 3 is sleeved on the outside of the thrust output shaft 11. The thrust output shaft 11 is connected to one end of the guide connector 4. When the thrust output shaft 11 retracts, all or part of the guide connector 4 is retracted into the positioning member 3. The positioning member 3 restricts the sliding or rotating movement of the thrust output shaft 11 of the force-controlled slide cylinder 1 during the extension operation. The other end of the guide connector 4 is a connecting shaft 41, which is sleeved with the contact connector 5. An elastic element 7 is sleeved on the connecting shaft 41, so that the elastic element 7 is positioned between the guide connector 4 and the contact connector 5; furthermore, a pin hole 42 is provided on the connecting shaft 41, and a guide pin groove 51 corresponding to the pin hole 42 is provided at one end of the contact connector 5 connected to the guide connector 4. A pin 43 is inserted into the guide pin groove 51 and the pin hole 42, and the contact connector 5 is restricted to move longitudinally by the pin 43 and the guide pin groove 51. A flexible contact 6 is provided at the other end of the contact connector 5. The end of the flexible contact 6 is hemispherical and the flexible contact 6 is made of conductive material.

[0034] During operation, the entire flexible touch head mechanism is mounted on other components such as a six-axis robotic arm or external motion mechanism. The guide connector 4, contact connector 5, and flexible contact 6 work in conjunction with the force-controlled slide cylinder 1 to perform click or page-turning actions on the touch screen 8, instruments, etc. Typically, the spring force of the spring 7 is between 0.5N and 9N. The flexible contact 6 is made of flexible conductive fiber cloth, using flexible pressure to contact the touch screen 8 or buttons, effectively protecting the touch screen 8 or buttons from damage by sudden external forces. The specific operation process is as follows: Figures 5a-5d As shown, in Figure 5a The middle contact connector 5 unfolds under the elastic force of the elastic member 7. At this time, the flexible contact 6 begins to extend or just touches the touch screen 8, but the flexible contact 6 does not generate contact pressure. Figure 5b The flexible contact 6 moves with the six-axis robotic arm or external motion mechanism, making contact with the touchscreen 8 and continuously receiving force from the six-axis robotic arm or external motion mechanism to press forward. At this time, the elastic element 7 is compressed, and the contact connector 5 moves in the direction of the guide pin groove 51; for example... Figure 5c The flexible contact 6 continues to be subjected to external force, and the elastic element 7 is compressed to its limit position and then fixed. The flexible contact 6 is compressed and contacts the touch screen 8. At this time, the force on the flexible contact 6 is transferred to the force-controlled slide cylinder 1; Figure 5dWhen the six-axis robotic arm or external motion mechanism continues to operate, the end of the flexible contact 6 begins to deform and compress, and the touch screen 8 or button is illuminated by the force. At this time, the force of the flexible contact 6 is transmitted to the force-controlled slide cylinder 1 and captured by the force control sensor. The force control sensor records the pressing force value in time. If the six-axis robotic arm or external motion mechanism continues to operate and the sensed force exceeds the set value, the control module 12 stops the six-axis robotic arm or external motion mechanism from continuing to output force, thereby protecting the touch screen 8 and the button.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
