[0034] Example 1, please refer to Figures 1 - 5 , this embodiment provides a conveying device for accurately positioning a tray, including a linear transmission mechanism 1 and a tray 3. The linear transmission mechanism 1 includes a bottom plate 11, on which a lead screw 12 is movably assembled, and a nut 13 is meshed and sleeved on the lead screw 12; one end of the bottom plate 11 is provided with a motor 14, and the output end of the motor 14 is connected to the lead screw 12; by driving the lead screw 12 to rotate through the motor 14, the nut 13 meshed with the lead screw 12 makes a linear displacement along the lead screw 12; a visual detection and positioning mark 31 is provided at the upper end of the tray 3, and a positioning hole 32 is provided at the lower end.

[0035] A planar adjustment mechanism 2 is provided at the output end of the linear transmission mechanism 1. The planar adjustment mechanism 2 includes a platform 21, an XY-axis slide 22 provided in the platform 21, and a positioning module 23 provided in the platform 21. The platform 21 is composed of a base 211 and a cover plate 212, and the cover plate 212 is detachably fitted on the upper end of the base 211, and the tray 3 is placed on the upper end of the cover plate 212; the XY-axis slide 22 includes a Y-axis adjustment module 221 and an X-axis adjustment module 222. The X-axis adjustment module 222 is provided at the upper end of the Y-axis adjustment module 221. The lower end of the Y-axis adjustment module 221 is connected to the base 211, and the upper end of the X-axis adjustment module 222 is connected to the cover plate 212; specifically, the Y-axis adjustment module 221 includes a Y-axis base 2211, a Y-axis slide 2212 slidably fitted on the Y-axis base 2211, and a Y-axis drive source 2213 for controlling the Y-axis slide 2212 to make a linear reciprocating motion on the Y-axis base 2211; the X-axis adjustment module 222 includes an X-axis base 2221, an X-axis slide 2222 slidably fitted on the X-axis base 2221, and an X-axis drive source 2223 for controlling the X-axis slide 2222 to make a linear reciprocating motion on the X-axis base 2221. The X-axis base 2221 is provided at the upper end of the Y-axis slide 2212; the XY-axis slide 22 can adjust the position of the tray 3 in the horizontal direction, which is convenient for material picking and placing.

[0036] The positioning module 23 includes a driving motor 231 and a positioning pin 232 connected to the output end of the driving motor 231. A weight sensor 233 is provided at the lower end of the driving motor 231. A through hole is provided in the corresponding area of the cover plate 212 for the positioning module 23. The upper end of the positioning pin 232 can pass through the cover plate 212 movably and be positioned at the lower end of the tray 3. During actual use, when the tray 3 adjusts its position through the planar adjustment mechanism 2, the driving motor 231 drives the positioning pin 232 to retract, without affecting the adjustment of the tray 3. When the tray 3 reaches the target position, the driving motor 231 drives the positioning pin 232 to extend and latch onto the tray 3, achieving the purpose of positioning the tray 3. The positioning module 23 can fix the position of the tray 3, avoid the position error of the material caused by the placement position difference between different trays, and improve the accuracy and consistency of the material processing position or the material grasping position. To judge the state of the material, if the weight sensor provided in the positioning module 23 receives an abnormal weight on the tray 3 during the extension of the positioning pin 232, the vision detection device will detect again whether the position of the positioning mark 31 is correct and make adjustments. If the action is repeated and it is still abnormal, the equipment will stop and alarm to ensure that it will not be conveyed to the working area at the wrong position, avoiding quality problems caused by the deviation of the conveying position of the product. And, since the position of the vision detection positioning mark 31 relative to the linear transmission mechanism has been determined, that is, the position of the tray 3 relative to the linear transmission mechanism 1 has been determined, therefore, the accuracy of the conveying is only controlled by the motor 14 and is not affected by external factors, with higher accuracy.

[0037] There are two positioning modules 23, and the two positioning modules 23 are diagonally distributed in the platform 21. The positioning pin 232 of one of the positioning modules 23 is cylindrical, and the positioning pin 232 of the other positioning module 23 is prismatic. A cylindrical pin can restrict 5 degrees of freedom, and a diamond-shaped positioning pin restricts the remaining 1 degree of freedom. Using a cylindrical pin and a diamond-shaped pin on a plate can fully position the plate. This combination ensures the stable fixation of the workpiece and avoids the problem of over-positioning.

[0038] In summary, the present utility model fixes the tray 3 in a lifting manner, which is suitable for fixing non-rigid trays 3, so that the tray 3 carrying the material is accurately positioned before conveying, ensuring the accuracy of the product conveying purpose during subsequent operations. The linear transmission mechanism 1 uses a screw-nut combination to achieve long-distance and stable conveying, with good overall conveying effect and high practicality. Therefore, the present utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
