DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] The present embodiment provides a planar gantry, which only needs two motors to realize the movement of the carrier 60 in the X-axis direction and the Y-axis direction, that is, it realizes the movement of the material in the X-axis direction and the Y-axis direction. Compared with the traditional gantry, it effectively reduces the cost and can make the overall thickness of the gantry smaller, so that the gantry can be used in a small space.

[0027] Combination Figures 1 to 4 As shown, the planar gantry of this embodiment includes two groups of first main beams 10 and first secondary beams 20 arranged in parallel, a second beam 30 arranged between the first main beam 10 and the first secondary beam 20, and a transmission belt 40. Under the action of the transmission belt 40, the second beam 30 can move along the length direction of the first main beam 10.

[0028] In this embodiment, a first main motor 11 is provided on the first main beam 10, a first auxiliary motor 21 is provided on the first auxiliary beam 20, and transmission rollers 50 are provided at both ends of the first main beam 10 and both ends of the first auxiliary beam 20. The first main motor 11 drives a transmission roller 50 on the first main beam 10, and the first auxiliary motor 21 drives a transmission roller 50 on the first auxiliary beam 20. The transmission belt 40 is installed on the transmission roller 50. When the first main motor 11 drives the transmission roller 50 or the first auxiliary motor 21 drives the transmission roller 50, the transmission belt 40 will be transmitted, thereby driving the second beam 30 to move, and a carrier 60 is provided on the second beam 30, and the carrier 60 is fixedly connected to the transmission belt 40. When the transmission belt 40 is driven, the carrier 60 moves along the length direction of the second beam 30.

[0029] Specifically, openings are provided on the first main beam 10 and the first auxiliary beam 20 , and the driving roller 50 is located in the openings.

[0030] In this embodiment, a first main wheel group 31 is provided at one end of the second beam 30 close to the first main beam 10, and a first secondary wheel group 32 is provided at one end close to the first secondary beam 20. The first main wheel group 31 and the first secondary wheel group 32 are symmetrically arranged. The first main wheel group 31 includes two first main rollers 311, and the first secondary wheel group 32 includes two first secondary rollers 321. The first main roller 311 and the first secondary roller 321 tighten the transmission belt 40, and the first main roller 311 and the first secondary roller 321 can pull the second beam 30 to make the second beam 30 move along the length direction of the first main beam 10.

[0031] Specifically, a first main mounting block 70 is provided at one end of the second beam 30 close to the first main beam 10, and a first secondary mounting block 80 is provided at one end close to the first secondary beam 20. The first main roller 311 is located on the first main mounting block 70, and the first secondary roller 321 is located on the first secondary mounting block 80. A first main roller 311 and a first secondary roller 321 corresponding to one position form a group of pulling structures, and another first main roller 311 and a first secondary roller 321 corresponding to another position form another group of pulling structures. The two groups of pulling structures can respectively pull the second beam 30 so that the second beam 30 moves along the length direction of the first main beam 10.

[0032] In this embodiment, the transmission belt 40 is sequentially arranged along the first main beam 10 , the second beam 30 , and the first auxiliary beam 20 to form a transmission structure.

[0033] Furthermore, a guide rail 33 is provided on the second crossbeam 30, the platform 60 is connected to the guide rail 33 through a slider 90, and guide tracks are provided in the first main crossbeam 10 and the first secondary crossbeam 20 to guide the movement of the second crossbeam 30 in the length direction of the first main crossbeam 10.

[0034] like Figure 5 As shown, the movement direction of the carrier 60 is explained below according to the forward and reverse rotation of the first main motor 11 and the first auxiliary motor 21, as shown in the following table.

[0035]

[0036] Combination Figure 5 As shown in the table above:

[0037] When the first main motor 11 and the first auxiliary motor 21 both rotate forward, the transmission belt 40 will be transmitted along the second direction, thereby driving the carrier 60 to be transmitted along the second direction;

[0038] When the first main motor 11 stops and the first auxiliary motor 21 rotates forward, the second beam 30 moves along the first direction, and the platform 60 moves along the second direction. Since the platform 60 is mounted on the second beam 30, the platform 60 moves between the first direction and the second direction.

[0039] When the first main motor 11 rotates in reverse and the first auxiliary motor 21 rotates forward, the transmission belt 40 transmits along the first direction, and under the action of the first main roller 311 and the first auxiliary roller 321, the second crossbeam 30 is pulled to move in the first direction, so that the carrier 60 moves in the first direction;

[0040] When the first main motor 11 rotates forward and the first auxiliary motor 21 stops, the second beam 30 moves along the third direction, and the carrier 60 moves along the second direction. Since the carrier 60 is mounted on the second beam 30, the carrier 60 moves between the second direction and the third direction.

[0041] When the first main motor 11 and the first auxiliary motor 21 are both in a stopped state, the carrier 60 is in a stationary state;

[0042] When the first main motor 11 is reversed and the first auxiliary motor 21 is stopped, the second beam 30 moves along the first direction, and the stage 60 moves along the fourth direction. Since the stage 60 is mounted on the second beam 30, the stage 60 moves between the first direction and the fourth direction.

[0043] When the first main motor 11 rotates forward and the first auxiliary motor 21 rotates reversely, the transmission belt 40 transmits along the third direction, and under the action of the first main roller 311 and the first auxiliary roller 321, the second crossbeam 30 is pulled to move in the third direction, so that the carrier 60 moves in the third direction;

[0044] When the first main motor 11 stops and the first auxiliary motor 21 reverses, the second beam 30 moves along the third direction, and the platform 60 moves along the fourth direction. Since the platform 60 is mounted on the second beam 30, the platform 60 moves between the third direction and the fourth direction.

[0045] When the first main motor 11 and the first auxiliary motor 21 are both reversed, the transmission belt 40 will be driven along the fourth direction, thereby driving the carrier 60 to be driven along the fourth direction.

[0046] In summary, within the plane constructed by the first main beam 10 and the first auxiliary beam 20, by changing the forward and reverse rotation of the first main motor 11 and the first auxiliary motor 21, the platform 60 can be placed at any point within the plane, which means that the platform 60 can be moved to any point within the plane, meeting the use requirements of the gantry and having stable accuracy.

[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
