[0027] To make the objectives, technical solutions and advantages of this utility model clearer, the following embodiments will be used to further describe this utility model in detail.

[0028] Figure 1 This is a schematic diagram of the installation structure of a drive control device according to an embodiment of the present invention; Figure 2 This is an exploded view of the structure of a drive control device according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the drive control device 100 is installed on the first track 3 and includes a first drive mechanism, a first connecting mechanism, a second connecting mechanism and a clutch mechanism connected in sequence. The first drive mechanism is connected to the first connecting mechanism, and the first connecting mechanism is connected to the second connecting mechanism. The friction wheel 1 is installed on the second connecting mechanism and is configured to rotate under the drive of the first drive mechanism. The clutch mechanism includes a second drive mechanism 25 and a transmission mechanism connected to the second drive mechanism 25. The transmission mechanism includes a rotatable first end 31. The friction wheel 1 is close to the first end 31 of the transmission mechanism and is configured to move closer to or further away from the second track 5 under the drive of the second drive mechanism 25. The second track 5 is perpendicular to the first track 3.

[0029] Specifically, Figure 1 The first track 3 and the second track 5 can be tracks of a certain height on an automobile production line. The first track 3 is, for example, an X-axis track, and the second track 5 is, for example, a Y-axis track. The drive control device 100 is installed on the first track 3 and is arranged parallel to the first track 3. It includes, in sequence, a first drive mechanism for driving the friction wheel 1 to rotate, a first connecting mechanism connecting the first drive mechanism and the friction wheel 1, a second connecting mechanism for mounting the friction wheel 1, and a clutch mechanism for driving the friction wheel 1 to move along the Z-axis to approach or move away from the second track 5. In this way, the friction wheel 1 can achieve self-rotation and generate friction when in contact with the second track 5, thereby causing the movement of the robot arm support on the second track 5.

[0030] Furthermore, the first driving mechanism includes a motor 13 and a reducer 15. The motor 13 is connected to the reducer 15, and the reducer 15 is connected to the first connecting mechanism. By setting the motor 13 and the reducer 15, the friction wheel 1 is driven to rotate. In addition, unlike the prior art where the motor 13 is installed along the Z-axis and requires an additional opening for installation, in this embodiment the motor 13 and reducer 15 are installed along the X-axis, which does not occupy Z-axis space and affect production operations. Furthermore, no opening for installing the motor 13 is left after removal.

[0031] Based on the above embodiments, in one implementation, a servo motor is used to achieve higher precision control.

[0032] Based on the above embodiments, the first connecting mechanism is a pair of eccentric couplings 11. For example... Figure 2 As shown, the eccentric coupling 11 has a first connecting end plate and a second connecting end plate at both ends. The first connecting end plate is connected to the output shaft of the reducer 15, and the second connecting end plate is connected to the second connecting mechanism. Thus, the eccentric coupling 11 enables the motor 13 to drive the rotation of the friction wheel 1, while simultaneously allowing the friction wheel 1 to have a certain space in both the X and Z directions to generate displacement. The application of the eccentric coupling 11 is existing technology. Those skilled in the art can select an eccentric coupling 11 with appropriate parameters for installation as needed without requiring creative effort; therefore, it will not be elaborated upon here.

[0033] Furthermore, the drive control device 100 also includes a mounting bracket 21 installed along the first track 3. The mounting bracket 21 includes a first end close to the first track 3 and a second end away from the first track 3. A second connecting mechanism is installed on the mounting bracket 21 and includes a first rotating shaft 23 and a second rotating shaft 53 parallel to the first track 3. The first rotating shaft 23 is disposed at the first end of the mounting bracket 21, and the second rotating shaft 53 is rotatably disposed at the second end of the mounting bracket 21 with respect to the first rotating shaft 23. A friction wheel 1 is sleeved on the outer periphery of the second rotating shaft 53.

[0034] In this embodiment, by setting a mounting bracket 21, on which a first rotating shaft 23 and a second rotating shaft 53 parallel to the first track 3 are mounted, the friction wheel 1 is mounted on the second rotating shaft 53, which is far from the first track 3 and can rotate around the first rotating shaft 23. In this way, the friction wheel 1 can rotate around the first rotating shaft 23, thereby generating vertical displacement, and thus moving closer to or away from the second track 5. A transition component, such as a bearing, is also included between the friction wheel 1 and the second rotating shaft 53. This structure is prior art and will not be elaborated here.

[0035] Furthermore, the second drive mechanism 25 includes a fixed first end and a retractable second end. The first end of the second drive mechanism 25 is fixed to the first end of the mounting bracket 21, and the second end of the second drive mechanism 25 is connected to the first end 31 of the transmission mechanism.

[0036] Based on this embodiment, the second drive mechanism 25 is fixed and the transmission mechanism is driven by connecting the movable end of the second drive mechanism 25 to the first end 31 of the transmission mechanism, so that it can produce vertical displacement, thereby driving the friction wheel 1 to rotate around the first rotating shaft 23.

[0037] Based on the above embodiments, the second drive mechanism 25 is a cylinder. Specifically, the first end of the second drive mechanism 25 is the tail of the cylinder output rod, which is fixed to the first horizontal plate of the mounting bracket 21 by fasteners such as bolts. The second end of the second drive mechanism 25 is the telescopic part of the cylinder output rod. The first end 31 of the transmission mechanism is provided with a vertical end plate, which is connected to the second end of the second drive mechanism 25 by a slider and fasteners such as bolts. In this way, the vertical end plate can be displaced as the cylinder output rod extends and retracts.

[0038] The following is combined with Figure 3 and Figure 4 The working principle of the drive control device according to an embodiment of this utility model is introduced. Figure 3 This is a schematic diagram showing the state of the friction wheel of the drive control device according to an embodiment of the present invention when it approaches the second track; Figure 4 This is a schematic diagram of the state of the friction wheel 1 of the drive control device according to an embodiment of the present invention when it is far away from the second track 5;

[0039] like Figure 3 and Figure 4 As shown, when the cylinder output rod is in the retracted state, the vertical end plate is located near the first end of the mounting bracket 21. At this time, the friction wheel 1 naturally falls away from the second track 5. When the cylinder output rod is in the extended state, the vertical end plate moves towards the second end of the mounting bracket 21. As it approaches the friction wheel 1, it causes the friction wheel 1 to be lifted upward around the first rotating shaft 23, approaching and reaching the second track 5, generating mutual friction with the second track 5. Furthermore, the friction wheel 1 itself is in a state of rotation due to the drive of the first driving mechanism.

[0040] Furthermore, a pair of connecting plates 41 are respectively provided at both ends of the first rotating shaft 23 and the two ends of the second rotating shaft, and the connecting plates 41 are configured to rotate around the first rotating shaft 23; and the second end 33 of the transmission mechanism is connected to the connecting plates 41.

[0041] Based on this embodiment, a connecting plate 41 that can rotate around the first rotating shaft 23 is provided, and the second end 33 of the transmission mechanism is connected to the base plate of the connecting plate 41 by fasteners such as bolts. In this way, the transmission mechanism can drive the connecting plate 41 and the friction wheel 1 installed on it to rotate around the first rotating shaft 23 under the drive of the second driving mechanism 25, so as to move closer to or away from the first track 3.

[0042] Furthermore, the mounting bracket 21 is provided with a first vertical plate, a second vertical plate and a third vertical plate that are parallel to the first track 3. One end of the first drive mechanism is connected to the first vertical plate, and the two ends of the first rotating shaft 23 are respectively mounted on the second vertical plate and the third vertical plate.

[0043] Specifically, the mounting bracket 21 is fixed on the first rail 3 by fasteners such as bolts, and includes a first horizontal plate abutting on the first rail 3, a first vertical plate arranged along the Y direction and perpendicular to the first horizontal plate, and a second vertical plate and a third vertical plate arranged along the Y direction and parallel to the first vertical plate; the output end of the first driving mechanism, for example, the output shaft of the speed reducer 15 is fixed on the first vertical plate by fasteners such as bolts; and the first rotating shaft 23 is arranged through the second vertical plate and the third vertical plate. Based on the embodiment, the installation of the device, for example, the first connecting mechanism and the second connecting mechanism, is realized.

[0044] Further, the mechanical hand mounting bracket 21 is mounted on the second rail 5 and is arranged to be capable of sliding along the second rail 5 by the friction driving of the friction wheel 1 and the second rail 5.

[0045] Based on the driving control device 100 of the above embodiment, the device is applied to a mechanical hand processing production line, the movement of the mechanical hand mounting bracket 21 on which the mechanical hand is mounted is driven by the action force of the friction wheel 1 and the second rail 5, so that the operation position of the mechanical hand can be positioned according to the requirement.

[0046] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
