Specific embodiments

[0044] The following will clearly and completely describe the technical solutions in the present invention in conjunction with the specific embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] Such as Figure 1-6As shown in the figure, the track translation transmission device of the present utility model includes a base 1, a slide rail 2, a belt conveyor 3, a positioning mechanism 4 and a translation mechanism 5.

[0046] Among them, the base 1 is used to carry other components.

[0047] The slide rail 2 is used to guide the belt conveyor 3, and the slide rail 2 is fixedly arranged on the base 1.

[0048] The belt conveyor 3 is used to convey workpieces. The belt conveyor 3 is slidably arranged on the slide rail 2. The belt conveyor 3 slides along the length direction of the slide rail 2. The conveying direction of the belt conveyor 3 is perpendicular to the length direction of the slide rail 2, so that two-dimensional movement of the workpieces can be realized.

[0049] The positioning mechanism 4 is used to limit the sliding range of the belt conveyor 3 on the base 1. The positioning mechanism 4 includes a mounting rod 41, a photoelectric switch 42 and a baffle 43. The mounting rod 41 is fixedly arranged on the base 1 and is parallel and spaced from the slide rail 2; the photoelectric switches 42 are respectively fixedly arranged at both ends of the mounting rod 41; the baffle 43 is fixedly arranged on the belt conveyor 3 and is located inside the photoelectric switch 42 or between two adjacent photoelectric switches 42; the photoelectric switch 42 is preferably of a U-type structure. As Figure 2 shown, when the baffle 43 moves into the photoelectric switch 42, the light beam inside the photoelectric switch 42 will be blocked or reflected, so that the change of the light beam inside the photoelectric switch 42 can be used to judge whether the baffle 43 and the belt conveyor 3 move to the position of the photoelectric switch 42, and then cooperate with the on-off switch to conduct on-off control on the control circuit of the belt conveyor 3, so as to realize the limitation of the movement range of the belt conveyor 3; the movement range of the belt conveyor 3 is the range between the photoelectric switches 42 at both ends of the mounting rod 41. If the belt conveyor 3 exceeds this range, the movement of the belt conveyor 3 will stop; the internal principle and structure of the photoelectric switch 42 are prior art.

[0050] There are many components and circuits on this transmission device. It is possible that other components or circuits accidentally pass by the photoelectric switch 42, affecting the judgment of the position of the belt conveyor 3 by the photoelectric switch 42. To solve this problem, two photoelectric switches 42 can be provided at at least one end of the mounting rod 41; preferably, the distance between the detection positions of the two photoelectric switches 42 located at the same end of the mounting rod 41 is equal to the width of the shielding plate 43. When the shielding plate 43 passes by the two photoelectric switches 42 at the same end of the mounting rod 41 in sequence, the signals indicating the presence of the shielding plate 43 recognized by these two photoelectric switches 42 are continuous. When an object smaller than the width of the shielding plate 43 passes by the two photoelectric switches 42 in sequence, the signals indicating the presence of the object recognized by the two photoelectric switches 42 are discontinuous. Therefore, the detection errors caused by objects smaller than the width of the shielding plate 43 can be filtered out. Similarly, the distance between the detection positions of the two photoelectric switches 42 located at the same end of the mounting rod 41 can also be made equal to twice the width of the shielding plate 43, and the time interval between the signals indicating the presence of the object recognized by these two photoelectric switches 42 can be used to determine whether the object is the shielding plate 43 or another object with the same width specification as the shielding plate 43, so as to reduce the detection errors caused by other objects, thereby improving the detection accuracy of the positioning mechanism 4.

[0051] As Figure 2 shown, a T-shaped groove 401 is provided on the mounting rod 41, and a bolt hole 402 is provided on the photoelectric switch 42, and the T-shaped groove 401 and the bolt hole 402 are detachably fixedly connected by bolts. This not only improves the connection convenience between the photoelectric switch 42 and the mounting rod 41, but also the position of the photoelectric switch 42 and the mounting rod 41 can be adjusted by loosening the bolts, thereby realizing the rapid adjustment of the moving range of the belt conveyor 3.

[0052] To improve the connection firmness between the photoelectric switch 42 and the mounting rod 41, preferably, two T-shaped grooves 401 are provided at intervals on each mounting rod 41, and the length direction of the T-shaped groove 401 is parallel to the length direction of the slide rail 2; two bolt holes 402 are provided on each photoelectric switch 42, and the two T-shaped grooves 401 and the two bolt holes 402 correspond to each other one by one.

[0053] As Figure 6 shown, the positioning mechanism 4 further includes infrared sensors 44. The infrared sensors 44 are respectively fixedly provided at both ends and the middle position of the belt conveyor 3. The infrared sensors 44 are used to detect whether there is a workpiece at the measured position, so as to let multiple infrared sensors 44 judge the position of the workpiece on the belt conveyor 3; among them, the principle and internal structure of the infrared sensors 44 are prior arts.

[0054] The translation mechanism 5 is used to drive the belt conveyor 3 to move automatically on the base 1. The translation mechanism 5 includes two first synchronous wheels 51, a first synchronous belt 52 and a translation motor 53. AsFigure 2 As shown in the figure, two first synchronous pulleys 51 are rotatably arranged on the base 1; a first synchronous belt 52 is sleeved outside the two first synchronous pulleys 51 and is fixedly connected to the belt conveyor 3 ( Figure 5 The vertical plate on the lower side of the belt conveyor 3 in the figure is fixedly connected to a part of the first synchronous belt 52); the translation motor 53 is fixedly arranged on the base 1, and its output end is coaxially and fixedly connected to one of the first synchronous pulleys 51; when the translation motor 53 is started, the first synchronous belt 52 can be driven to rotate, so as to drive the belt conveyor 3 connected to the first synchronous belt 52 to move.

[0055] As Figure 4 shown in the figure, a plurality of reinforcing grooves 501 are formed on the circumferential side of the first synchronous pulley 51, and the plurality of reinforcing grooves 501 are arranged in a circumferential array around the center line of the first synchronous pulley 51. The formation of the reinforcing grooves 501 makes the circumferential side of the first synchronous pulley 51 uneven, thereby increasing the friction between the first synchronous pulley 51 and the first synchronous belt 52; specifically, it is preferably to set the cross section of the reinforcing groove 501 to be an isosceles trapezoid shape, that is, to make the whole first synchronous pulley 51 have a gear-like structure and have uniform rotation.

[0056] As Figure 5 and Figure 6 shown in the figure, the belt conveyor 3 includes a conveying frame 31, two conveying rails 32, a lead screw 33, a distance adjusting motor 34, two second synchronous pulleys 35 and a second synchronous belt 36.

By using the sliding of the conveying rail 32 and the conveying frame 31, the distance between the two conveying rails 32 can be adjusted, so that the belt conveyor 3 can adapt to workpieces of different specifications.

[0057] The lead screw 33 is rotatably arranged on the conveying frame 31 and is threadedly engaged with the conveying rail 32 slidably connected to the conveying frame 31; the distance adjusting motor 34 is fixedly arranged on the conveying frame 31; the two second synchronous pulleys 35 are respectively coaxially fixed on the lead screw 33 and the output end of the distance adjusting motor 34; the second synchronous belt 36 is sleeved outside the two second synchronous pulleys 35; when the distance adjusting motor 34 is started, by using the cooperation of the second synchronous pulley 35 and the second synchronous belt 36, the lead screw 33 can be driven to rotate, so that by using the threaded engagement between the lead screw 33 and one of the conveying rails 32, this conveying rail 32 can slide on the conveying frame 31.

[0058] As Figure 5 and Figure 6As shown in the figure, the conveying rail 32 includes a guiding frame 321, a conveying motor 322, a plurality of third synchronous pulleys 323 and a third synchronous belt 324. The guiding frame 321 is arranged on the conveying frame 31; the conveying motor 322 is fixedly arranged on the guiding frame 321; the plurality of third synchronous pulleys 323 are respectively rotatably arranged on the guiding frame 321 and coaxially fixed on the output end of the conveying motor 322; the third synchronous belt 324 is sleeved outside the plurality of third synchronous pulleys 323; when the conveying motor 322 is started, the cooperation of the third synchronous pulleys 323 and the third synchronous belt 324 can be utilized to drive the third synchronous belt 324 to rotate, so as to convey the workpiece by using the third synchronous belt 324.

[0059] The using method of the track translation transmission device of the present utility model is as follows:

[0060] First, control the distance-adjusting motor 34 to adjust the distance between the two conveying rails 32 to adapt to the specifications of the workpieces to be conveyed. Then start the conveying motor 322 to drive the third synchronous belt 324 to rotate. Next, control the translation motor 53 to move the belt conveyor 3 to the position of the workpiece receiving end, so that the workpiece is transferred from the previous process to the belt conveyor 3. Finally, control the translation motor 53 to move the belt conveyor 3 to the position of the workpiece output end, so that the workpiece is transferred from the belt conveyor 3 to the next process; before this, the positions of the photoelectric switches 42 at both ends of the mounting rod 41 can be adjusted to be respectively located at the positions of the workpiece receiving end and the workpiece output end, so that the belt conveyor 3 can move within the range between the workpiece receiving end and the workpiece output end.

[0061] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
