Description

Technical Field

[0001] This invention relates to the field of machining technology, and more specifically, to an automatic milling chip collection method and system for sample milling. Background Technology

[0002] After production, steel mills must test the chemical composition of the steel to analyze the effects of residual or added elements and to verify whether the steel meets quality requirements. This mainly involves testing and analyzing the sample chips from quick-separation samples and the surface of the processed samples. Currently, the chip collection method is entirely manual. First, a drilling machine is used to drill the sample surface at low speed, and then the drilled iron chips are collected. This method is labor-intensive, has low automation, and the manual operation has a high risk factor. It is very easy to cause confusion of chips from different types of samples, which will ultimately affect the test and analysis results. The chip sampling efficiency is also low. Summary of the Invention

[0008] S6. The drilling machine stops working, and the articulated robot picks up the chip collection cup and the sample respectively, and places them on the unloading rack;

[0009] S7. Repeat the above steps to collect multiple sets of sample chips. During the collection of multiple sets of sample chips, when the articulated robot picks up the chip collection cup and places it on the unloading rack, it arranges the multiple sets of sample chips in sequence.

[0014] S32, The articulated robot picks up the sample from the laser marking machine and places it at the drilling machine fixture station.

[0015] Optionally, the step of repeating the above steps to collect multiple sets of sample debris, and during the collection of multiple sets of sample debris, after the articulated robot picks up the debris collection cup and places it onto the unloading rack, and arranges the multiple sets of sample debris in sequence, further includes:

[0016] S8. Remove the chip collection cup and pour the chip samples from the chip collection cup into paper bags one by one;

[0017] S9. The label printer prints a label with the number and affixes it to the paper bag.

[0018] Optionally, the chip collection device includes a chip-removing cover, a chip-collecting cup, and a rotating disk. The rotating disk and the chip-removing cover are located on the same side of the drilling machine fixture station and are both connected to the drilling machine. The rotating disk is provided with a chip-collecting cup, which is detachably connected to the rotating disk. The chip-removing cover is used to receive the sample chips and pour them into the chip-collecting cup. The rotating disk rotates around its central axis so that the chip-collecting cup rotates between the area below the chip-removing cover and the gripping position of the articulated robot. The articulated robot grips the chip-collecting cup.

[0019] Optionally, before the drilling machine operates and the chip collecting device collects the sample chips generated by the drilling machine during the machining of the sample into the chip collecting cup, the method further includes:

[0020] S4. Rotate the rotating disk until the chip collection cup is directly below the chip removal cover.

[0021] Optionally, the drilling machine stops working, and the articulated robot picks up the chip collection cup and the sample respectively, and places them on the unloading rack, including:

[0022] S61. The drilling machine stops working, and the rotating disk rotates until the chip collection cup is located in the gripping position of the articulated robot.

[0023] S62. The articulated robot picks up the chip collection cup and the sample respectively and places them on the unloading rack.

[0026] Compared with the prior art, the beneficial effects of the automatic milling chip collection method for samples described in this invention are:

[0027] This invention utilizes a loading and unloading rack. Samples are first placed on the loading rack, and an articulated robot picks them up from the rack and moves them to a drilling machine fixture. The drilling machine operates, milling the samples. Milling chips are collected by a chip collection device and placed in chip cups. The drilling machine stops, and the articulated robot picks up the samples and chip cups separately and places them on the unloading rack. The articulated robot sequentially picks up different samples from the loading rack and moves them to the drilling machine for milling, with chip cups collecting the chips. The articulated robot then sequentially places multiple chip cups, each containing multiple sets of chips, onto the unloading rack. This process, using the articulated robot and chip cups for sampling, replaces manual sampling, reducing the risk of danger, saving time, and achieving automated milling and chip collection. This improves chip collection efficiency. Furthermore, when multiple sets of samples need to be tested, the collected chips are arranged sequentially, preventing sample mixing and facilitating differentiation, further enhancing chip collection efficiency.

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0041] Furthermore, although specific embodiments have been described herein, it should be understood that these embodiments are merely examples of the principles and applications of the invention. Therefore, it should be understood that many modifications can be made to the exemplary embodiments, and other arrangements can be designed without departing from the spirit and scope of the invention as defined by the appended claims. It should be understood that different dependent claims and features described herein can be combined in ways different from those described in the original claims. It is also understood that features described in conjunction with individual embodiments can be used in other described embodiments.

[0042] To solve the above problems, such as Figure 1 and Figure 4 As shown, the present invention provides a method for automatic milling and chip collection of samples, comprising the following steps:

[0043] S2. Place the sample on the loading rack 1;

[0044] S3. The articulated robot 2 picks up the sample from the loading rack 1 and places it in the fixture station of the drilling machine 3;

[0045] S5. The drilling machine 3 operates, and the chip collection device 5 collects the sample chips generated by the drilling machine 3 during the processing of the sample into the chip collection cup;

[0046] S6. The drilling machine 3 stops working, and the articulated robot 2 picks up the chip collection cup 52 and the sample respectively, and places them on the unloading rack 4;

[0047] S7. Repeat the above steps to collect multiple sets of sample chips. During the collection of multiple sets of sample chips, when the articulated robot 2 clamps the chip collection cup 52 onto the unloading rack 4, it arranges the multiple sets of sample chips in sequence.

[0048] In this embodiment, by setting up a loading rack 1 and a unloading rack 4, the sample is first placed on the loading rack 1. The articulated robot 2 clamps the sample from the loading rack 1 and moves it to the fixture position of the drilling machine 3. The drilling machine 3 operates to mill the sample. The milling chips are collected by the chip collection device 5 and placed in the chip collection cup 52. The drilling machine 3 stops working, and the articulated robot 2 clamps the sample and the chip collection cup 52 onto the unloading rack 4 respectively. The articulated robot 2 sequentially clamps different samples from the loading rack 1 to the drilling machine 3 for milling. The sample chips are collected by the chip collection cups 52. The articulated robot 2 sequentially places multiple chip collection cups 52, each containing multiple sets of sample chips, onto the unloading rack 4. This process, which uses the articulated robot 2 and the chip collection cups 52 for sampling, replaces manual sampling, reducing the risk of danger, saving time, and realizing automatic milling chip collection. This improves the chip collection efficiency. Furthermore, when multiple sets of samples need to be tested, the collected chip chips are arranged in order, making it less likely for samples to mix and easier to distinguish between multiple sets of sample chips, thus improving the chip collection efficiency.

[0049] Optionally, such as Figure 1 As shown, before placing the sample on the loading rack 1, the process further includes:

[0050] S1. Number the samples.

[0051] In this embodiment, by numbering the samples before processing them on the drilling machine 3, it is easier to distinguish the samples, less likely to mix samples, and improves the efficiency of sample chip collection.

[0052] Optionally, such as Figure 2 As shown, the articulated robot 2 picks up the sample from the loading rack 1 and places it in the fixture station of the drilling machine 3, including:

[0053] S31. The articulated robot 2 picks up the sample from the loading rack 1 and places it on the laser marking machine 6. The laser marking machine 6 marks the sample with the number.

[0054] S32, The articulated robot 2 picks up the sample from the laser marking machine 6 and places it in the fixture station of the drilling machine 3.

[0055] In this embodiment, the articulated robot 2 picks up the sample from the loading rack 1 and places it on the laser marking machine 6. The laser marking machine 6 prints the sample number on the sample. Then, the articulated robot 2 picks up the numbered sample and places it on the fixture station of the drilling machine 3. This makes it easier to distinguish between the sample and the sample chips, prevents sample mixing, and improves the efficiency of sample chip collection.

[0056] Optionally, such as Figure 1 As shown, the process of repeating the above steps to collect multiple sets of sample debris, and during the collection of multiple sets of sample debris, when the articulated robot 2 clamps the debris collection cup 52 onto the unloading rack 4, after arranging the multiple sets of sample debris in sequence, further includes:

[0057] S8. Remove the chip collection cup 52 and pour the chip samples in the chip collection cup 52 into the paper bag in turn;

[0058] S9. Label printer 7 prints a label with the number and affixes it to the paper bag.

[0059] In this embodiment, the sample scraps collected in the scrap collection cup 52 are poured into a paper bag, and the label printer 7 prints the sample number corresponding to the sample scrap. The number is then affixed to the paper bag. The number on each paper bag corresponds one-to-one with the sample number corresponding to the sample scrap in the paper bag, which facilitates the differentiation of the sample and the sample scrap, prevents sample mixing, and improves the sample scrap collection efficiency. When collecting multiple sets of sample scraps, the multiple sets of sample scraps are poured into different paper bags in sequence, and the number on each paper bag is consistent with the sample number corresponding to the sample scrap in the paper bag.

[0060] Optionally, such as Figure 5 As shown, the chip collection device 5 includes a chip-removing cover 53, a chip-collecting cup 52, and a rotating disk 51. The rotating disk 51 and the chip-removing cover 53 are located on the same side of the fixture station of the drilling machine 3 and are both connected to the drilling machine 3. The rotating disk 51 is provided with a chip-collecting cup 52, which is detachably connected to the rotating disk 51. The chip-removing cover 53 is used to receive the sample chips and pour them into the chip-collecting cup 52. The rotating disk 51 rotates around its central axis so that the chip-collecting cup 52 rotates between the position below the chip-removing cover 53 and the gripping position of the articulated robot 2. The articulated robot 2 grips the chip-collecting cup 52.

[0061] In this embodiment, a chip-removing cover 53, a chip-collecting cup 52, and a rotating disk 51 are provided. Both the rotating disk 51 and the chip-removing cover 53 are connected to one side of the machining station of the drilling machine 3. The chip-collecting cup 52 is mounted on the rotating disk 51 and is detachably connected to it. The rotating disk 51 can drive the chip-collecting cup 52 to rotate below the chip-removing cover 53. One end of the chip-removing cover 53 has a cover-like structure. The sample chips generated during sample machining enter the chip-removing cover 53 under the centrifugal force generated by the rotation of the drilling machine 3's cutting tool. The other end of the chip-removing cover 53 is tubular. The sample chips enter the chip collection cup 52 through the tubular structure and are collected by the chip collection cup 52. After the processing is completed, the rotating disk 51 rotates and rotates the chip collection cup 52 to a position that is convenient for the articulated robot 2 to grasp. The articulated robot 2 grasps the chip collection cup 52 and places it on the unloading rack 4. The chip collection cup 52 is small in size and easy to grip. It is also convenient for the operator to collect the sample chips in the chip collection cup 52 into a paper bag. The rotating disk 51 rotates and rotates the chip collection cup 52 to the end away from the processing station of the drilling machine 3, so that the articulated robot 2 can grasp the chip collection cup 52.

[0062] Optionally, such as Figure 1 As shown, before the drilling machine 3 operates and the chip collecting device 5 collects the sample chips generated by the drilling machine 3 during the processing of the sample into the chip collecting cup 52, it further includes:

[0063] S4. Rotate the rotating disk 51 until the chip collection cup 52 is directly below the chip removal cover 53.

[0064] In this embodiment, by rotating the rotating disk 51, the chip collection cup 52 is rotated to be directly below the chip deflector 53, so that the sample chips generated by the drilling machine 3 during sample processing can be collected into the chip collection cup 52 through the chip deflector 53.

[0065] Optionally, such as Figure 3 As shown, the drilling machine 3 stops working, and the articulated robot 2 picks up the chip collection cup 52 and the sample respectively, and places them on the unloading rack 4, including:

[0066] S61. The drilling machine 3 stops working, and the rotating disk 51 rotates until the chip collection cup 52 is located in the gripping position of the articulated robot 2.

[0067] S62. The articulated robot 2 picks up the chip collection cup 52 and the sample respectively and places them on the unloading rack 4.

[0068] In this embodiment, when the drilling machine 3 stops working, the rotating disk 51 is rotated, and the rotating disk 51 drives the chip collection cup 52 to rotate to a position that is convenient for the articulated robot 2 to grasp. The articulated robot 2 then clamps the chip collection cup 52 and the sample to the unloading rack 4, making it easier for the articulated robot 2 to grasp the chip collection cup 52.

[0069] Optionally, such as Figure 3 and Figure 5As shown, the chip collection device 5 also includes a blower pipe 54, which is mounted on the drilling machine 3. The blower pipe 54 is used to blow air into the chip discharge hood 53. After the articulated robot 2 picks up the chip collection cup 52 and the sample respectively and places them on the unloading rack 4, it also includes:

[0070] S63. The air blowing pipe 54 blows air into the chip removal hood 53 to blow away the sample chips remaining in the chip removal hood 53.

[0071] In this embodiment, by setting an air blower 54 on the drilling machine 3, after the drilling machine 3 finishes processing the sample and stops working, there are sample chips generated by the sample that were just processed in the chip removal cover 53. The air blower 54 can blow air into the chip removal cover 53 to blow away the sample chips in the chip removal cover 53, so that there are no sample chips in the chip removal cover 53, preventing the sample chips generated in the previous processing from mixing into the sample chips generated in the next processing, which would affect the accuracy of the sample chip inspection.

[0072] Another embodiment of the present invention provides an automatic milling chip collection system for specimens, used to implement the above-mentioned automatic milling chip collection method for specimens. The automatic milling chip collection system for specimens includes a loading rack 1, a unloading rack 4, an articulated robot 2, and a chip collection device 5.

[0073] The chip collection system for automatic milling of samples described in this invention has roughly the same beneficial effects as the chip collection method for automatic milling of samples, and will not be repeated here.

[0074] Optionally, such as Figure 4 As shown, the automatic milling chip collection system for the sample also includes an industrial computer 8, which is used to control the articulated robot 2 to grip the sample and the chip collection cup 52.

[0075] In this embodiment, by setting up an industrial computer 8, the industrial computer 8 controls the articulated robot 2 to pick up the sample from the loading rack 1, controls the start and stop of the drilling machine 3, controls the rotation of the turntable 51, controls the articulated robot 2 to pick up the sample and the chip collection cup 52 onto the unloading rack 4, and arranges multiple sets of chip collection cups 52 in sequence, controls the laser marking machine 6 and the label printer 7 to work, and controls the overall process of the sample milling chip collection system. The industrial computer 8 controls the automatic sample milling chip collection method, connects each step of milling chip collection together, saves time, and realizes automatic milling chip collection.

[0076] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
