DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0036] Example 1

[0037] A specific embodiment of the present invention discloses a support plate device for conveying workpieces, such as Figure 1 As shown, an azimuthally rotating roller assembly 1101 and a lateral rotating roller assembly 1102 are rotatably mounted on the material support plate 11; wherein, when the azimuthally rotating roller assembly 1101 rotates, it can push the conveyed article to achieve azimuth rotation; when the lateral rotating roller assembly 1102 rotates, it can push the conveyed article to shift left and right along the width direction of the material support plate 11; that is, in this embodiment, by adjusting the rotation of the conveyed article through the azimuthally rotating roller assembly 1101, the shortest side of the conveyed article can be adjusted to align with the middle scanning hole of the scanning assembly, thereby achieving the passability of large-sized workpieces. By adjusting the left and right offset of the conveyed article through the lateral rotating roller assembly 1102, the conveyed article is aligned with the middle scanning hole of the scanning assembly, thereby avoiding the risk of the conveyed article being unable to pass through the scanning system or being scratched on the side due to the offset of the conveyed article.

[0038] Furthermore, if Figure 1 As shown, the azimuthally rotating roller assemblies 1101 are provided in multiple groups that are centrally symmetrical; preferably, the azimuthally rotating roller assemblies 1101 are provided in four groups, and the four groups of azimuthally rotating roller assemblies 1101 are arranged at intervals of 90° in the circumferential direction.

[0039] Furthermore, in this embodiment, one or more groups of lateral rotating roller assemblies 1102 are arranged along the length direction of the material pallet 11; the rotation axis of the lateral rotating roller assembly 1102 is parallel to the conveying direction of the workpiece conveying mechanism 1; that is, the rotation axis of the lateral rotating roller assembly 1102 is arranged perpendicular to the scanning system.

[0040] Specifically, when multiple sets of lateral rotating roller assemblies 1102 are provided, the multiple sets of lateral rotating roller assemblies 1102 are arranged linearly, such as Figure 1 shown.

[0041] Furthermore, a first mounting groove 1103 and a second mounting groove 1104 are provided on the material support plate 11 ; the azimuth rotating roller assembly 1101 is rotatably mounted in the first mounting groove 1103 , and the lateral rotating roller assembly 1102 is rotatably mounted in the second mounting groove 1104 .

[0042] In this embodiment, the azimuth rotating roller assembly 1101 and the lateral rotating roller assembly 1102 both include: a rotating shaft 1105 and a rotating roller 1106; the rotating roller 1106 is fixedly mounted on the rotating shaft 1105 and can be driven to rotate by the rotating shaft 1105; the rotating roller 1106 is a cam structure, and when the rotating shaft 1105 drives the rotating roller 1106 to rotate, the protruding portion of the rotating roller 1106 is rotated out of the upper surface of the material support plate 11 or rotated into the first mounting groove 1103.

[0043] Preferably, a plurality of rotating rollers 1106 are fixedly mounted on a rotating shaft 1105; Figure 2 、 Figure 3 As shown, three rotating rollers 1106 are fixedly mounted on the rotating shaft 1105 . When the rotating shaft 1105 rotates, the three rotating rollers 1106 can be driven to rotate synchronously.

[0044] Specifically, in the present invention, the azimuth rotating roller assembly 1101 and the lateral rotating roller assembly 1102 are driven independently, and the rotational movements of the azimuth rotating roller assembly 1101 and the lateral rotating roller assembly 1102 are not performed simultaneously; that is, the rotating roller assemblies independently adjust the azimuth angle and left and right displacement of the conveyed items.

[0045] During implementation, when the rotating roller 1106 of the azimuth rotating roller assembly 1101 rotates out of the upper surface of the material support plate 11 and rolls in contact with the lower surface of the conveyed article, it can push the conveyed article to rotate around the symmetry center of the multiple groups of azimuth rotating roller assemblies 1101, thereby adjusting the azimuth angle of the conveyed article; when the rotating roller 1106 of the lateral rotating roller assembly 1102 rotates out of the upper surface of the material support plate 11 and rolls in contact with the lower surface of the conveyed article, it can push the conveyed article to deviate left and right, thereby aligning it with the middle scanning hole of the scanning assembly.

[0046] In a specific embodiment of the present invention, Figure 4 、 Figure 5 As shown, the rotating roller 1106 is composed of a rotating sleeve 1106a and a half-moon shaped protrusion 1106b.

[0047] Specifically, the rotating sleeve 1106a is a cylindrical sleeve.

[0048] Specifically, if Figure 5 As shown, the two half-moon shaped protrusions 1106b form a group and are symmetrically arranged on the upper and lower sides of the rotating sleeve 1106a.

[0049] Furthermore, if Figure 4 As shown, the half-moon shaped protrusions 1106b are arranged in a plurality of groups in an array along the axis direction of the rotating sleeve 1106a.

[0050] In this embodiment, the half-moon-shaped protrusion 1106b is made of rubber material to avoid surface damage to the conveyed object when pushing the conveyed object to move.

[0051] Furthermore, when the crescent-shaped protrusion 1106b is vertically upward, the crescent-shaped protrusion 1106b of the rotating roller 1106 protrudes from the upper surface of the material pallet 11 and can contact the conveyed objects on the material pallet 11; when the crescent-shaped protrusion 1106b is horizontal, the rotating roller 1106 is lower than the upper surface of the material pallet 11 and does not contact the conveyed objects on the material pallet 11.

[0052] During implementation, as the rotating shaft 1105 drives the rotating roller 1106 to rotate, the half-moon shaped protrusion 1106b continuously applies lateral force to the conveyed objects on the material support plate 11, thereby pushing the conveyed objects to rotate circumferentially or translate.

[0053] In a specific embodiment of the present invention, two groups of lateral rotating roller assemblies 1102 are provided, and the two groups of lateral rotating roller assemblies 1102 are coaxially arranged; the two rotating shafts 1105 of the two groups of lateral rotating roller assemblies 1102 are fixedly connected and can rotate synchronously under the drive of the first rotating motor.

[0054] In a specific embodiment of the present invention, Figure 2 As shown, the azimuth rotating roller assembly 1101 also includes: a first spur gear 1107; the first spur gear 1107 is fixedly mounted on the rotating shaft 1105; and the diameter of the first spur gear 1107 is smaller than the diameter of the rotating sleeve 1106a of the rotating roller 1106, thereby keeping the first spur gear 1107 lower than the upper surface of the material support plate 11, avoiding contact between the first spur gear 1107 and the conveyed items.

[0055] Furthermore, the multiple groups of azimuth rotating roller assemblies 1101 rotate synchronously driven by the second rotating motor and the rotating transmission assembly.

[0056] like Figure 6As shown, the rotation transmission assembly includes: a second spur gear 1108 , a third spur gear 1109 , a first bevel gear 1110 , a second bevel gear 1111 , a transmission rod 1112 and a fourth spur gear 1114 .

[0057] Specifically, the second spur gear 1108 is horizontally arranged below the material support plate 11, and the second spur gear 1108 is simultaneously engaged with multiple third spur gears 1109, and can drive the multiple third spur gears 1109 to rotate synchronously.

[0058] Furthermore, the first bevel gear 1110 is fixedly connected to the third spur gear 1109 through the second mounting shaft 1116, and the first bevel gear 1110 is arranged in parallel above the third spur gear 1109; in this embodiment, by arranging the first bevel gear 1110 and the third spur gear 1109 to be coaxially mounted, the synchronous rotation of the two is achieved.

[0059] Furthermore, the first bevel gear 1110 is meshed with the second bevel gear 1111 for transmission; in this embodiment, the direction of the rotating axis is converted from a vertical direction to a horizontal direction through the meshing transmission of the first bevel gear 1110 and the second bevel gear 1111, thereby realizing the rotation of the vertically arranged second bevel gear 1111.

[0060] Furthermore, the transmission rod 1112 is disposed below the material support plate 11 and is arranged parallel to the material support plate 11. One end of the transmission rod 1112 is fixedly mounted with the second bevel gear 1111, and the other end is fixedly mounted with the fourth spur gear 1114. The fourth spur gear 1114 is disposed below the material support plate 11 and meshes with the first spur gear 1107. In this embodiment, the four sets of transmission rods 1112 and fourth spur gears 1114 transmit rotational power to the first spur gears 1107 of the four sets of azimuth rotating roller assemblies 1101, thereby enabling the synchronous rotation of the four sets of rotating shafts 1105 and rotating rollers 1106. When the multiple rotating rollers 1106 rotate synchronously, they can simultaneously apply thrust to the material support plate 11 to promote its rotational motion.

[0061] In this embodiment, during the rotation of the rotating roller 1106, when it rotates to a state where it protrudes from the upper surface of the material support plate 11, the semi-lunar protrusion 1106b on its surface can exert an inclined upward force on the conveyed items above the material support plate 11. The vertical component of the inclined force can achieve a slight lifting effect on the conveyed items, thereby reducing the mutual friction between the conveyed items and the surface of the material support plate 11 during rotation; the horizontal component of the inclined force is used to promote the rotation of the conveyed items and realize the circumferential position adjustment of the conveyed items.

[0062] During implementation, the second spur gear 1108 rotates under the drive of the second rotating motor, and can synchronously drive multiple third spur gears 1109 to rotate. The first bevel gear 1110 rotates synchronously with the third spur gear 1109 and can drive the second bevel gear 1111 to rotate. When the second bevel gear 1111 rotates, it can drive the fourth spur gear 1114 to rotate through the transmission rod 1112, and then drive the first spur gear 1107 to rotate through the fourth spur gear 1114, thereby realizing the synchronous rotation of multiple groups of azimuth rotating roller assemblies 1101.

[0063] Furthermore, the number of the third spur gears 1109 , the transmission rods 1112 and the fourth spur gears 1114 is equal to the number of the azimuth rotation roller assemblies 1101 .

[0064] Specifically, if Figure 6 As shown, the second spur gear 1108 is fixedly connected to the first mounting shaft 1115 and is rotatably mounted below the material support plate 11 through the first mounting shaft 1115 ; the first mounting shaft 1115 is arranged perpendicular to the material support plate 11 .

[0065] Specifically, if Figure 6 As shown, a plurality of second mounting shafts 1116 are provided, and the plurality of second mounting shafts 1116 are provided around the first mounting shaft 1115 ; further, the second mounting shaft 1116 is rotatably installed below the material support plate 11 through a bearing.

[0066] Specifically, if Figure 6 As shown, at least one transmission rod support 1113 is provided on the transmission rod 1112, and the transmission rod support 1113 is fixedly connected to the lower surface of the material support plate 11; the transmission rod 1112 is rotatably connected to the transmission rod support 1113 through a bearing, and then the transmission rod 1112 is rotatably hoisted below the material support plate 11 through the transmission rod support 1113.

[0067] In this embodiment, by providing a rotary transmission assembly, multiple fourth spur gears 1114 are meshed with the first spur gears 1107 of the multiple azimuth rotating roller assemblies 1101, thereby achieving synchronous rotation of the multiple azimuth rotating roller assemblies 1101. When the multiple azimuth rotating roller assemblies 1101 rotate synchronously, they can simultaneously provide lateral forces to the conveyed items above the material pallet 11, and the multiple sets of lateral thrusts provided by the multiple azimuth rotating roller assemblies 1101 are continuous in the circumferential direction, thereby driving the conveyed items to rotate. In other words, the rotational torques provided by the multiple azimuth rotating roller assemblies 1101 to the conveyed items are in the same direction and are all used to drive the conveyed items to rotate clockwise or counterclockwise, achieving the superposition of multiple sets of rotational torques, and achieving circumferential angle adjustment of the conveyed items while minimizing the force acting on the surface of the conveyed items.

[0068] In this embodiment, the material support plate 11 of the workpiece conveying mechanism is improved and designed so that the position of the large-sized workpiece can be adjusted while carrying and lifting the large-sized workpiece.

[0069] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
