First embodiment

Referring to fig. 1 to 3, a top view, a schematic structural view and a side view of the transportation device in the first embodiment are respectively shown. As shown, the transportation device includes a first transportation portion 100, a second transportation portion 200, a first transition portion 300, a carrying portion 400, and a second transition portion 500. The first transition portion 300 and the second transition portion 500 have the same structure. The number of the carrying parts 400 is several, and the number can be increased or decreased according to the product transportation requirement. The products to be transported are placed on the carrier 400.

The first transition 300 and the second transition 500 are both located between the first transport portion 100 and the second transport portion 200. The carrier 400 is movable on the first transport part 100, the second transport part 200, the first transition part 300, and the second transition part 500 to deliver the product to a target location.

Referring to fig. 4, a side view of the load bearing portion in the first embodiment is shown. As shown, the carrier 400 includes a mover 410, a slider 420, a mover holder 430, and a stage 440. The mover 410 and the sliders 420 are fixed to the bottom of the mover base 430, and two sliders 420 are respectively disposed at both sides of the mover 410. The stage 440 is fixed to the top of the mover base 430, and the product to be transported is placed on the stage 440.

Referring to fig. 5, a side view of the first transport section in the first embodiment is shown. The first transporting portion 100 includes a first stator 110, a first slide rail 120, and a first stator holder 130. The first stator 110 and the first slide rail 120 are fixed on the top of the first stator base 130, and two sides of the first stator 110 are respectively provided with one first slide rail 120.

Referring to fig. 6, a side view of the second transport section in the first embodiment is shown. The second transporting portion 200 includes a second stator 210, a second slide rail 220, and a second stator holder 230. The second stator 210 and the second slide rail 220 are fixed on the top of the second stator seat 230, and two sides of the second stator 210 are respectively provided with one second slide rail 220.

Referring to fig. 7 to 9, a schematic structural view, a side view and a front view of the first transition portion in the first embodiment are respectively shown. The first transition portion 300 includes a carrying portion 310 and a transition portion linear motor 320. The conveying unit 310 includes a third stator 311, a third slide rail 312, and a third stator holder 313. The third stator 311 and the third slide rail 312 are fixed on the top of the third stator seat 313, and two sides of the third stator 311 are respectively provided with one third slide rail 312. The carrying unit 310 is fixed to the top of the transition unit linear motor 320 by a third stator holder 313. The transition linear motor 320 can drive the conveying part 310 to move along the first transition part 300. The cross sections and the extending directions of the third stator 311 and the first stator 110 are the same, and the cross sections and the extending directions of the third stator 311 and the second stator 210 are also the same, that is, the third stator 311 can be regarded as an extension of the first stator 110 and can be regarded as an extension of the second stator 210.

When the bearing part 400 is located on the first transporting part 100, the mover 410 is located at the top of the first stator 110 with a gap therebetween, and the slider 420 is clamped on the first slide rail 120 and can slide along the first slide rail 120. The mover 410 and the first stator 110 form a first linear motor, and current parameters of coils in the mover 410 are adjusted, so that the mover 410 moves along the first stator 110, and thus, a product placed on the bearing portion 400 is driven to move together. The movement principle between the mover 410 and the first stator 110 is a basic knowledge of the linear motor, and thus is not described in detail. When the mover 410 drives the product placed on the bearing portion 400 to be transported to the end portion of the first transporting portion 100 (corresponding to the vicinity of the first end of the first transition portion 300), the end surface of the first stator 110 is in contact with and aligned with the end surface of the third stator 311, and the transporting portion 310 can be regarded as an extension of the first transporting portion 100. At this time, the mover 410 forms a second linear motor with the third stator 311, so that the mover 410 continues to move along the third stator 311 to approach the transition portion linear motor 320. When the mover 410 reaches right above the transition portion linear motor 320, the coils in the mover 410 are de-energized. The handling part 310, the carrying part 400 and the products will move together along the first transition part 300 under the driving of the transition part linear motor 320 until reaching the second end of the first transition part 300 (corresponding to the vicinity of the end of the second transport part 200). At this time, the end surface of the third stator 311 is aligned with and in contact with the end surface of the second stator 210, and the second transport unit 200 may be regarded as an extension of the conveying unit 310. The transition linear motor 320 is then de-energized and the coils in the mover 410 are energized. The second linear motor continues to operate moving mover 410 along third stator 311 to move away from transition linear motor 320. When the mover 410 reaches above the second stator 210, they constitute a third linear motor so that the mover 410 moves along the second stator 210. The process of transporting from the second transporting portion 200 to the second transition portion 500 and then to the first transporting portion 100 is similar to the above process, and thus is not described again.

When the product is transported to the target position, the mover 410 is powered off, so that the product stays there. After the product is processed at the position, the coil in the rotor 410 is electrified, so that the product can be continuously driven to move to the next station, the transportation direction and the transportation speed can be changed by adjusting the current parameter of the coil, and the adjustment is very convenient and fast. Generally speaking, when different products are produced, the positions of the stations to be parked can be different, so that the transportation lines are generally required to be arranged separately for different products. But the conveyer in this scheme can be berthhed at any time according to the position of station, consequently, need not to set up the line of transportation alone to every kind of product, and application scope is wider, very big saving the cost.

In this embodiment, the first transportation portion 100 is parallel to the second transportation portion 200, and the first transition portion 300 is parallel to the second transition portion 500, and the four portions form a rectangle. The number of the transition parts can be increased, so that the whole transportation device is in a shape like a Chinese character 'ri', a Chinese character 'tian', and the like.

Second embodiment

This embodiment is an alternative embodiment to the first embodiment, in which the handling section 310 in the first transition section 300 is rotationally connected with the transition section linear motor 320. Specifically, a driving device, such as a motor or a cylinder, may be disposed on the transition portion linear motor 320, and the driving device is used to drive the conveying portion 310 to rotate in the horizontal plane. Thus, the first transportation portion 100 and the second transportation portion 200 may not be parallel, the first transition portion 300 and the second transition portion 500 may not be parallel, and the four portions may form a trapezoid, a parallelogram or any other trapezoid. In the present embodiment, when the mover 410 reaches the first end of the first transition portion 300, the orientation of the third stator 311 is the same as that of the first stator 110, and when the mover reaches the second end of the first transition portion 300, the conveying portion 310 may be driven by the driving device to turn the direction, so that the orientation of the third stator 311 is the same as that of the second stator 210.

The embodiments of the present invention have been described in detail, but the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope of the present invention defined by the claims.
