[0004] (1) With the passage of time, each single device in the packing system will inevitably experience wear and aging, resulting in a decrease in accuracy and affecting the overall packing stability. At this time, it is necessary to replace the device with lower accuracy, which will undoubtedly Shorten the service life of the equipment and increase inspection and maintenance costs;
[0005] (2) The boxing system does not optimize the accuracy of each sub-equipment item by item, thus increasing the uncertainty of the system error. In the later maintenance process, equipment maintenance personnel are required to check and analyze item by item, which increases labor costs; And the random and uncertain errors in the system have a great impact on the quality and efficiency of packing, and there is a risk of damage to equipment and parts
[0006] (3) The errors are distributed in different sub-item equipment, the cumulative error is large, and the accuracy is insufficient

Embodiment 1
[0036] Such as figure 1 As shown, the present invention provides a kind of method for improving the precision of automatic packing system, comprises the following steps:
[0037] (1) Adjust the accuracy of the storage location: take the robot that grabs the parts through the mechanical arm as the accuracy standard, install a tooling needle on the 6# axis of the mechanical arm, the tooling needle can be purchased from the market, move the robot, and pass the tooling The needle is fixed on the four positioning pins (P1, P2, P3, P4) of the first pallet (T1), and the coordinates of the positioning pins of the first pallet are obtained. in the system;
[0038]Based on the coordinates of the positioning pins of the first pallet, repeat the first pallet in and out of each storage location (ST1, ST2, ST3, ST4, ST5, ST6, etc.) at least 3 times to verify the position of a single pallet in each storage location. Repeat positioning accuracy, if the repeat positioning accuracy error of t...
Embodiment 2
[0048] The difference from Embodiment 1 is that the specified range, precision error, horizontal distance error, numerical error, and error involved can be the same value, or can be partially the same or completely different, and can be adjusted according to the actual situation, but no matter How to set the error range, the optimization method in this embodiment is quantitative recording, and the error range of each step can be adjusted according to the final actual needs, so as to ensure that the entire cumulative error is within an acceptable range.
[0049] For example, each error range is 0.3mm or 0.6mm, etc., which are adjusted according to the actual situation.

Abstract
The invention discloses a method of improving the precision of an automatic packing system. The method comprises the steps of adjusting storage location precision, adjusting tray precision, arranginga standard gauge with standard perpendicularity and levelness and adjusting material box precision. According to the method, repetitive locating precision of storage locations, trays and material boxes is optimized respectively, and an error of each part can be controlled within a designated range; a control variable method is adopted to measure and optimize each set of sub-equipment assisted by arobot as a benchmark, so that the design is scientific, and the precision of the storage locations, the trays and the material boxes is optimized in a linked mode; and repetitive locating detection is performed in each step of optimization, so that an accumulated error of the whole system is lowered, and the reliability of the stamping automatic packing system is guaranteed. Besides, the debugging cycle of the stamping automatic packing system is greatly shortened, manual measurement errors are reduced, the method is simple and easy to operate, and later maintenance and rectification are convenient.
Description
technical field [0001] The invention relates to the technical field of end-of-line operation of a stamping automatic production line, in particular to a method for improving the precision of an automatic packing system. Background technique [0002] The working process of the existing automatic boxing system at the end of the stamping automatic production line is: the end-sequence robot grabs the formed parts from the end-sequence press and places them on the belt conveyor, and after positioning through the additionally prepared industrial vision system, Then it is grabbed by the end-of-line frame loading robot and placed in the precision material frame, and then transported to the stamping warehouse by AGV. [0003] However, the cost of the industrial vision system is expensive, and in the existing boxing system, except for the robot, other sub-equipment are non-standard equipment, and the manufacturers of each sub-equipment are different, and the manufacturer's processing ...
