AI Technical Summary
Existing robots can only move in two directions. Adding a third direction of movement requires laying more tracks, resulting in high structural costs and a large footprint.
A four-axis column manipulator is designed, which realizes flexible movement in three-dimensional space through the combined movement of longitudinal and transverse support arms, combined with a rotating base and motor drive, and reduces the dependence on additional tracks.
The four-axis motion of the robot is realized without adding tracks, which reduces the use cost and floor space, and improves flexibility and applicability.

DETAILED DESCRIPTION
[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0023] Example
[0024] like Figure 1-Figure 7 As shown, this embodiment includes a support base 1 with one side capable of being connected to the equipment and providing support, a longitudinal support arm 2 vertically connected to the support base 1 and providing a vertical path for the manipulator, a transverse support arm 3 connected to the longitudinal support arm 2 and providing a transverse path for the manipulator, a movable arm 4 disposed within the transverse support arm 3, and a rotating base 5 disposed at the distal end of the movable arm 4 for connecting to the manipulator's claw and providing rotational functionality. The support base 1 has a first rotation slot 11 at its top end for connecting to the longitudinal support arm 2, and a connector 21 at its bottom end that mates with the first rotation slot 11. The longitudinal support arm 2 is connected to the support base 1 through the connector 21 and the first rotation slot 11. A first motor 22 is fixed within the longitudinal support arm 2, capable of driving the longitudinal support arm 2 to rotate. Specifically, driven by the first motor 22, the longitudinal support arm 2 can rotate a certain angle around the axis of the first rotation slot 11, thereby driving all components connected to the longitudinal support arm 2 to rotate together.
[0025] like Figure 1-Figure 7As shown, a first longitudinal track 23 is provided on one side of the longitudinal support arm 2, and a second longitudinal track 24, parallel to the first longitudinal track 23, is provided on the other side of the longitudinal support arm 2. A second motor 25 is fixed to the top of the longitudinal support arm 2. The second motor 25 is provided with a movable gear 26 that can rotate under the drive of the second motor 25. A mating gear 27 is provided above the second motor 25 and is fixed to the longitudinal support arm 2 and located next to the movable gear 26. A counterweight slider 28 is provided on the second longitudinal track 24, which can move along the second longitudinal track 24. A transverse support arm 3 is provided on the first longitudinal track 23, which can move along the first longitudinal track 23. A transmission rack 29 is provided between the counterweight slider 28 and the transverse support arm 3, connecting the two. The transmission rack 29 passes outside the movable gear 26 and the mating gear 27 and is meshed with the movable gear 26 and the mating gear 27. Specifically, when the movable gear 26 rotates under the drive of the second motor 25, it can drive the transmission rack 29 to move, thereby driving the counterweight slider 28 and the transverse support arm 3 connected at both ends thereof to change their height in the vertical direction. The rotation direction of the movable gear 26 determines the direction of movement of the two. The counterweight slider 28 plays a role in stabilizing the movement process of the transverse support arm 3 in this process, and at the same time reduces the force required by the second motor 25 during the upward movement of the transverse support arm 3, so as to extend its service life.
[0026] like Figure 1-Figure 7 As shown, a cavity 31 for the movable arm 4 to move and a third motor 32 provided with a driving gear 33 are provided in the transverse support arm 3. A rack 41 capable of cooperating with the driving gear 33 is provided on the side of the movable arm 4. A part of the movable arm 4 is provided in the cavity 31, and the other part of the movable arm 4 is located outside the cavity 31, and the driving gear 33 is meshed with the rack 41. Specifically, by driving the driving gear 33 to rotate through the third motor 32, the movable arm 4 can be moved in the cavity 31, so that the movable arm 4 moves relative to the transverse support arm 3 in the direction of the transverse support arm 3, thereby driving the mechanical hand claw connected to the end of the movable arm 4 located outside the cavity 31 to change its position relative to the transverse support arm 3 (including moving away from the transverse support arm 3 and approaching the transverse support arm 3).
[0027] like Figure 1-Figure 7 As shown, a downwardly opening rotating cavity 42 is formed at the lower distal end of the movable arm 4, and a rotating base 5 is movably connected to the rotating cavity 42. A fourth motor 43 is fixed to the other side of the movable arm 4 to drive the rotating base 5 to rotate. The fourth motor 43 passes through the movable arm 4 and is in transmission connection with the rotating base 5 in the rotating cavity 42. Specifically, when the fourth motor 43 is in operation, the rotating base 5 can rotate within the rotating cavity 42 about the center of the rotating cavity 42.
[0028] like Figure 1-Figure 7As shown, both the rotating base 5 and the rotating cavity 42 are provided with a through hole 6 that penetrates the rotating base 5 and is positioned in a coordinated manner. The through hole 6 can be used to fix the robotic claw part in the rotating cavity 42. When the rotating base 5 rotates under the drive of the fourth motor 43, it can drive the robotic claw part connected thereto to rotate.
[0029] like Figures 1-4 As shown, the third motor 32 is covered with a first protective cover 7 fixed on the transverse support arm 3, and the fourth motor 43 is covered with a second protective cover 8 fixed on the movable arm 4. The first protective cover 7 and the second protective cover 8 both play a role in protecting the motors.
[0030] like Figure 1-Figure 7 As shown, both the rotating base 5 and the rotating cavity 42 are provided with a through hole 6 that penetrates the rotating base 5 and is positioned in a coordinated manner. The through hole 6 can be used to fix the robotic claw part in the rotating cavity 42. When the rotating base 5 rotates under the drive of the fourth motor 43, it can drive the robotic claw part connected thereto to rotate.
[0031] like Figures 1-4 As shown, the third motor 32 is covered with a first protective cover 7 fixed on the longitudinal support arm 3, and the fourth motor 43 is covered with a second protective cover 8 fixed on the movable arm 4. The first protective cover 7 and the second protective cover 8 both play a role in protecting the motors.
[0032] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
