Description

[0028] This invention provides a support and docking mechanism, such as Figure 1As shown, it includes a type A supporting mechanism 1 and a type B supporting mechanism 2. Type A supporting mechanism 1, from bottom to top, includes a leveling pad A1-1, a base A1-2, a lateral movement mechanism 1-3, a longitudinal movement mechanism A1-4, and a support mechanism A1-5. Four sets of leveling pads A1-1 are located at the four corners below the base A1-2, and four eye bolts A1-6 are installed on both sides of the base A1-2. Type B supporting mechanism 2, from bottom to top, includes a leveling pad B2-1, a base B2-2, a longitudinal movement mechanism B2-3, and a support mechanism B2-4. Four sets of leveling pads B2-1 are located at the four corners below the base B2-2, and four eye bolts B2-5 are installed on both sides of the base B2-2. Type A supporting mechanism 1 has lateral movement and longitudinal movement / support functions, while Type B supporting mechanism 2 has longitudinal movement / support functions. Type A supporting mechanism 1 achieves docking between the supporting platform A and the supporting platform B of type B supporting mechanism 2 through the lateral movement mechanism. To ensure that the spacing of the joints along the length of the support platform after docking is no more than 2mm, the height difference is no more than 0.5mm, and the lateral misalignment is no more than 2mm, the total height of the type A support mechanism and the type B support mechanism is the same, and the type A support mechanism 1 and the type B support mechanism 2 are parallel along the length of the support platform, with the parallelism adjusted to within 1mm.

[0029] like Figure 2 As shown, the lateral moving mechanism 1-3 includes a lateral moving guide rail 1-3-1 and a lateral driving cylinder 1-3-2; the longitudinal moving mechanism A1-4 includes a connecting plate A1-4-1, a longitudinal moving guide rail A1-4-2 and a longitudinal moving cylinder A1-4-3; the connecting plate A1-4-1 is mounted on the slider of the lateral moving guide rail 1-3-1 and is connected to the piston rod of the lateral driving cylinder 1-3-2 through a mounting connector.

[0030] like Figure 3 As shown, the longitudinal moving mechanism B2-3 includes a connecting plate B2-3-1, a longitudinal moving guide rail B2-3-2, and a longitudinal moving cylinder B2-3-3. The connecting plate B2-3-1 is mounted on the base B2-2.

[0031] like Figure 4 As shown, support mechanism A1-5 includes support frame A1-5-1, grounding copper plate A1-5-2, and pin A1-5-3. Grounding copper plate A1-5-2 is mounted on support frame A1-5-1, and pin A1-5-3 is mounted on the grounding copper plate. Support mechanism B2-4 includes support frame B2-4-1, grounding copper plate B2-4-2, and pin B2-4-3. Grounding copper plate B2-4-2 is mounted on support frame B2-4-1, and pin B2-4-3 is mounted on the grounding copper plate B2-4-2.

[0032] According to a specific embodiment of the present invention, pin A1-5-3 and pin B2-4-3 are positioning pins or guide pins.

[0033] According to one specific embodiment of the present invention, the maximum speed of the support mechanism in all directions is 3m / min, and it has a multi-level adjustable function.

[0034] According to a specific embodiment of the present invention, the working process of the holding and docking mechanism is as follows:

[0035] The omnidirectional mobile platform carries the support platform B into platform 1. Using QR code navigation for positioning, it adjusts its parking position after arrival, ensuring the support platform's pin hole is within the movement range of the positioning pin of the support mechanism B. The omnidirectional mobile platform's movement function is locked, and the support platform B prepares to begin its positioning, awaiting the extension of the B-type support mechanism.

[0036] When the B-type support mechanism's motion function is unlocked, the longitudinal movement cylinder of the B-type support mechanism drives the longitudinal movement mechanism and support mechanism B to move out of the platform and into the underside of the support platform B.

[0037] The floating mechanism of the omnidirectional mobile platform is unlocked, the lifting motion is unlocked, the support platform B descends to the height of the guide pin entering the pin hole, and continues to fall until the positioning pin enters the pin hole, until the support platform B is fully in contact and stable with the support mechanism B of the support mechanism B. The support platform B is in place and the omnidirectional mobile platform drives out of platform 1.

[0038] The omnidirectional mobile platform carries the support platform A into platform 2. Using QR code navigation for positioning, it adjusts its parking position after arrival, ensuring the support platform's pin hole is within the movement range of the guide pin of the support mechanism A. The omnidirectional mobile platform's movement function is locked, and support platform A prepares to begin its positioning, awaiting the extension of the A-type support mechanism.

[0039] The longitudinal movement cylinder of the A-type support mechanism drives the longitudinal movement mechanism A and the support mechanism A to move out of the platform and into the underside of the support platform A. The floating mechanism of the omnidirectional moving platform is unlocked, the lifting movement is unlocked, and the support platform 2 descends until it is fully in contact with and stable with the support mechanism A of the A-type support mechanism, completing the positioning. The omnidirectional moving platform drives out of the platform 2, and the movement function of the A-type support mechanism is locked.

[0040] The A-type support mechanism, activated by a lateral movement cylinder, drives support platform A to align with support platform B supported by support mechanism B until the joint gap is no greater than 2mm, the height difference is no greater than 0.5mm, and the lateral misalignment is no greater than 2mm. This completes the alignment process. Figure 5 As shown.
