Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] First of all, in the description of the embodiments of the present application, it needs to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0038] In addition, the “and / or” in this application, such as “Feature 1 and / or Feature 2”, refers to the three cases that it can be “Feature 1” alone, “Feature 2” alone, or “Feature 1” plus “Feature 2”. The “and / or” in this application, such as “Feature 1 and / or Feature 2”, refers to the three cases that it can be “Feature 1” alone, “Feature 2” alone, or “Feature 1” plus “Feature 2”.

[0039] See also Figure 1 The conveyor line 1 of the first embodiment of the present application includes a stator module 10 and a mover 20. The mover 20 can move on the stator module 10 along the conveying direction of the conveyor line 1. More specifically, as follows:

[0040] Combination Figure 2-4 As shown, the stator module 10 has a straight segment 101 and an arc segment 102 , and the straight segment 101 and the arc segment 102 both include a driving unit 11 , a base 12 , a first guide member 13 and a second guide member 14 , and the mover 20 has a mover body 21 , a driven unit 22 , a support assembly 23 and a guide assembly 24 .

[0041] The driving unit 11 is arranged on the base 12, and the driven unit 22 is arranged on the mover body 21. The driven unit 22 can move under the drive of the driving unit 11 to drive the mover body 21 to move along the conveying direction on the conveying line 1, so that the mover 20 moves along the conveying direction of the conveying line 1 under the drive of the stator module 10;

[0042] The base 12 is arranged along the conveying direction of the conveyor line 1, and the first guide member 13 and the second guide member 14 are extended and arranged along the base 12. The first guide member 13 is located on the outside of the base 12, and the second guide member 14 is located on the inside of the base 12, so that under the guiding restriction between the guide assembly 24 and the first guide member 13 and the second guide member 14, the mover 20 moves smoothly along the base 12.

[0043] like Figure 2-4 As shown, the guide assembly 24 includes two first rollers 241 and two second rollers 242. The two first rollers 241 are located on one side of the mover body 21, and the two second rollers 242 are located on the other side of the mover body 21. The spacing W1 between the two first rollers 241 is greater than the spacing W2 between the two second rollers 242, so that the mover 20 can smoothly pass through the process of switching between the straight line segment 101 and the arc segment 10a. Of course, in other embodiments, the first rollers can also be one, three, four, five, etc., and the second rollers can also be one, three, four, five, etc., so it is not limited to this.

[0044] like Figure 1-4 As shown, when the mover 20 moves in the straight segment 101 and / or the arc segment 102, the two first rollers 241 are constantly in contact with the first guide member 13, and the two second rollers 242 are constantly in contact with the second guide member 14, thereby ensuring that the mover 20 moves smoothly in the straight segment 101 and / or the arc segment 102, greatly reducing the shaking of the mover 20, so that the object carried by the mover 20 moves smoothly, but not limited to this.

[0045] like Figure 2-3As shown, the support assembly 23 is disposed on the stator module 10 to carry the mover body 21 , so that the mover 20 can be stably disposed on the stator module 10 , but the present invention is not limited thereto.

[0046] like Figure 2-4 As shown, the width of the portion of the mover body 21 located between the first guide member 13 and the second guide member 14 is smaller than the spacing between the first guide member 13 and the second guide member 14 to ensure that the mover body 21 is always separated from the first guide member 13 and the second guide member 14 during the movement on the conveyor line 1.

[0047] like Figure 2-4 As shown, the first roller 241, the second roller 242 and the support assembly 23 are located on the same side of the base 12, and the first roller 241 and the second roller 242 are located on the side of the support assembly 23 away from the base 12, so that the internal structure of the mover 20 is reasonably compact, and the structure between the stator module 10 and the mover 20 is reasonably compact.

[0048] like Figure 2-4 As shown, a first limiting portion 13 a is provided on one side of the first guide member 13 away from the base 12 to limit the first roller 241 from sliding out of the first guide member 13 in a direction away from the base 12 , thereby limiting the mover 20 from sliding out of the stator module 10 in a direction away from the base 12 .

[0049] like Figure 2-4 As shown, a second limiting portion 14 a is provided on the side of the second guide surface away from the base 12 to limit the second roller 242 from sliding out of the second guide member 14 in a direction away from the base 12 , thereby limiting the mover 20 from sliding out of the stator module 10 in a direction away from the base 12 .

[0050] like Figure 2-4 As shown, the size of the first roller is equal to the size of the second roller to reduce costs. Of course, in other embodiments, the size of the first roller can also be larger than the size of the second roller, so that when the mover moves in the arc segment, the first roller located on the outside can better resist the centrifugal force exerted on the mover 20, thereby ensuring that the mover moves smoothly in the arc segment.

[0051] like Figure 2-4 As shown, the two first rollers 241 have the same size to facilitate the location setting and cost control of the first rollers 241 , but the present invention is not limited thereto.

[0052] like Figure 2-4 As shown, the two second rollers 242 have the same size to facilitate the location setting and cost control of the second rollers 242 , but the present invention is not limited thereto.

[0053] like Figure 2-4As shown, the support assembly 23 includes eight support rollers 231 arranged on the mover body 21, and the support rollers 231 are located on the side of the mover body 21 close to the base 12, so that the mover 20 can be rotatably arranged on the base 12 through the support rollers 231, thereby reducing the movement friction between the mover 20 and the stator module 20.

[0054] For example, the first roller 241 is an elastic body to compensate for the gap between the first roller 241 and the first guide member 13, or compensate for the gap between the second roller 242 and the second guide member 14 when the mover 20 moves in the straight segment 101 and / or the arc segment 102, but it is not limited thereto.

[0055] For example, the second roller 242 is an elastic body to compensate for the gap between the first roller 241 and the first guide member 13, or the gap between the second roller 242 and the second guide member 14 when the mover 20 moves in the straight segment 101 and / or the arc segment 102, but it is not limited thereto.

[0056] For example, the first guide member 13 or the second guide member 14 is an elastic body to compensate for the gap between the first roller 241 and the first guide member 13, or compensate for the gap between the second roller 242 and the second guide member 14 when the mover 20 moves in the straight segment 101 and / or the arc segment 102, but it is not limited to this.

[0057] For example, an elastic structure is arranged between the first roller 241 and the mover body 21, and the first rolling body can move toward the first guide member 13 under the elastic drive of the elastic structure to compensate for the gap between the first roller 241 and the first guide member 13, or compensate for the gap between the second roller 242 and the second guide member 14 when the mover 20 moves in the straight segment 101 and / or the arc segment 102, but it is not limited to this.

[0058] For example, an elastic structure is arranged between the second roller 242 and the mover body 21, and the second rolling body can move toward the second guide member 14 under the elastic drive of the elastic structure to compensate for the gap between the second roller 242 and the second guide member 14, or compensate for the gap between the first roller 241 and the first guide member 13 when the mover 20 moves in the straight segment 101 and / or the arc segment 102, but it is not limited to this.

[0059] For example, the first guide member 13 is provided with an elastic structure, and the first guide member 13 can move toward the first roller 241 under the elastic drive of the elastic structure to compensate for the gap between the first roller 241 and the first guide member 13, or compensate for the gap between the second roller 242 and the second guide member 14 when the mover 20 moves in the straight segment 101 and / or the arc segment 102, but it is not limited to this.

[0060] For example, the second guide member 14 is provided with an elastic structure, and the second guide member 14 can move toward the second roller 242 under the elastic drive of the elastic structure to compensate for the gap between the second roller 242 and the second guide member 14, or compensate for the gap between the first roller 241 and the first guide member 13 when the mover 20 moves in the straight segment 101 and / or the arc segment 102, but it is not limited to this.

[0061] like Figure 3 As shown, the stator module 10 also includes a mounting frame 15, which is located on one side of the base 12 and connected to the base 12, and the first guide member 13 and the second guide member 14 are located on the other side of the base 12 and are reasonably compact with the internal structure of the stator module 10 respectively.

[0062] like Figure 1-4 As shown, during the movement and switching of the mover 20 between the straight segment 101 and the arc segment 10b, the contact point between the first roller 241 and the first guide member 13 is offset relative to the mover body 32, and the contact point between the second roller 242 and the second guide member 14 is offset relative to the mover body 32, so as to ensure that the mover 20 moves smoothly on the stator module 10. Specifically, during the movement and switching of the mover 20 between the straight segment 101 and the arc segment 10b, the offset of the contact point between the first roller 241 and the first guide member 13 relative to the mover body 21 is greater than the offset of the contact point between the second roller 242 and the second guide member 14 relative to the mover body 21, so as to further ensure that the mover 20 moves smoothly on the stator module 10.

[0063] like Figure 4 As shown, the rotation center line of each first roller 241 and the rotation center line of each second roller 242 are parallel, and on the projection plane perpendicular to the rotation center line of any first roller 241, the two projected guide components 24 are symmetrical to each other, so that the two guide components 24 are reasonably compact and further ensure the smooth movement of the mover 20 between the straight segment 101 and the arc segment 10b.
