Description

Technical Field

[0001] The utility model relates to the technical field of CNC bed processing of precision engraving machines, and more specifically, to a fully automatic loading and unloading precision engraving machine. Background Art

[0002] With the rapid development of modern science and technology and the fierce market competition, the technical content and complexity of automated processing equipment have become increasingly enhanced. Optimizing the efficiency and effect of automated processing equipment has become a goal that manufacturing giants and developers are vying for. The loading process in automated machinery production is an important part of the production process, and its main function is to supply product materials to product processing devices. In the current production environment, especially for the processing of precision parts such as mobile phone covers and protective films, the efficiency of this link is directly related to the operating efficiency of the entire production line.

[0003] At present, products such as smartphone covers and protective sheets on the market need to be processed by CNC bed. There are many types of such CNC bed, but they often have low efficiency when facing the fine carving of mobile phone covers, protective sheets, etc. On the one hand, many fine carving machines still need to rely on manual labor when performing loading and unloading operations, which is not only inefficient, but also increases labor costs. And manual loading and unloading faces risks such as misoperation, which may have a negative impact on product quality. On the other hand, although there are some manipulators on the market that can load and unload materials automatically, these devices often use four heads to process at the same time, and their efficiency has not been really improved. This is because in this way, although multiple heads can be processed at the same time, the efficiency of the bed cannot be maximized. For example, when one part is processed and needs to be unloaded, the rest of the parts may not have been processed yet. At this time, if you wait for all parts to be processed before unloading at one time, the waiting time for some of the processed parts will be too long, which will reduce efficiency; and if the unloading operation is performed separately for the completed parts, it is necessary to switch the operation mode frequently, which will also lose efficiency.

[0023] The first Y-axis drive assembly 20 and the second Y-axis drive assembly 30 are fixedly mounted on the bed 10. The first Y-axis drive assembly 20 and the second Y-axis drive assembly 30 are both provided with two rows of four-side positioning fixtures 301, four in a row, a total of eight. The first Y-axis drive assembly 20 and the second Y-axis drive assembly 30 can drive multiple four-side positioning assemblies to move back and forth along the Y-axis direction of the bed 10, so that the workpiece can maintain a precise position during the processing, thereby improving the processing accuracy. The loading and retrieving mechanism 70 is mounted on one side of the bed 10, and is slidably connected to the bed 10, and can move back and forth along the Y-axis direction of the bed 10. The loading conveyor belt 40 is mounted on the bed 10, and the loading conveyor belt 40 is arranged between the loading and retrieving mechanism 70 and the first Y-axis drive assembly 20. The X-axis of the manipulator assembly 60 is parallel to the X-axis of the machine tool, and the Z-axis of the manipulator assembly 60 is parallel to the Z-axis of the machine tool. The manipulator assembly 60 is mounted on the bed 10 and can move back and forth along the X-axis direction of the bed 10. , the manipulator assembly 60 is provided with eight manipulator suction cups 601, which are arranged in a row, and the odd-numbered and even-numbered manipulator suction cups 601 are respectively provided with a first cylinder 602 and a second cylinder 609 for separate driving, the crossbeam 50 is arranged above the first Y-axis drive assembly 20 and the second Y-axis drive assembly 30, the crossbeam 50 is arranged along the X-axis of the bed 10, and is fixedly connected to the bed 10, and two rows of Z-axis drive assemblies 501 are also arranged on the crossbeam 50, four in a row, a total of eight. The Z-axis drive assembly 501 can move back and forth along the crossbeam 50, and the multiple Z-axis drive assemblies 501 are all provided with a processing spindle 502 facing one end of the bed 10. Each group of four-side positioning fixtures 301, the odd-numbered manipulator suction cups, the even-numbered manipulator suction cups, and each group of Z-axis drive assemblies 501 are arranged to keep the spacing between each two. The robot assembly 60 can pick up eight pieces at the same time when taking materials, and can also release the materials separately without interfering with each other, thereby shortening the entire cycle time, improving efficiency, and saving equipment costs and labor costs for customers.

[0024] Further, the manipulator assembly 60 also includes a manipulator X-axis drive assembly 603, a manipulator Z-axis drive assembly 604, a manipulator slide rail 605, a manipulator 606, a first column 607, and a second column 608; the first column 607 and the second column 608 are arranged on the bed 10, one end of which is fixedly connected to the bed 10, and the other end is fixedly connected to the manipulator slide rail 605, one end of the manipulator Z-axis drive assembly 604 is fixedly connected to the manipulator, and the other end is slidably connected to the manipulator slide rail 605, and the manipulator X-axis drive assembly 603 is installed on the manipulator slide rail 605 to drive the manipulator Z-axis drive assembly 604. The manipulator assembly 60 enables the manipulator 606 to complete precise positioning in the X-axis and Z-axis in a short time through the manipulator X-axis drive assembly 603 and the manipulator Z-axis drive assembly 604, so that the movement of the manipulator 606 is more stable, and the processing quality of the product is improved.

[0025] Furthermore, one side of the bed 10 is provided with a material loading and retrieving mechanism 70, and a slide 101 is provided. A material receiving box 102 is also provided on the bed 10. The material loading and retrieving mechanism 70 includes a first material loading box 701, a second material loading box 702, a mounting seat cylinder 703 and a retrieving mechanism mounting seat 704;

[0026] The material taking mechanism mounting seat 704 is slidably connected to the slide 101, the first loading box 701 and the second loading box 702 are mounted on the material taking mechanism mounting seat 704, the first loading box 701 and the second loading box 702 are both provided with a loading lifting assembly 705, the mounting seat cylinder 703 is provided on the bed 10, and its output end is fixedly connected to the material taking mechanism mounting seat 704, and one of the first loading box 701 and the second loading box 702 can be aligned with the loading conveyor 40 through the mounting seat cylinder 703. By providing two loading boxes, two different workpieces or a large number of the same workpieces can be stored at the same time, which can greatly improve production efficiency and reduce downtime caused by changing workpieces. When the mounting seat cylinder 703 is retracted, the position of the first loading box 701 overlaps with the position of the loading conveyor belt 40, which is convenient for the loading and taking mechanism 70 to take materials. When the materials in the first loading box 701 are used up, the mounting seat cylinder 703 is opened, and the position of the second loading box 702 overlaps with the position of the loading conveyor belt 40, which is convenient for the loading and taking mechanism 70 to take materials. At this time, the first loading box 701 can be manually fed, and the loading lifting component 705 can adjust the height of the workpiece to align it with the loading conveyor belt 40, so that no matter how big the workpiece is, it can be smoothly loaded. Due to the automatic alignment of the loading box and the conveyor belt, the difficulty of operation is reduced and the work efficiency is improved.

[0027] Furthermore, the eight Z-axis drive assemblies 501 are arranged on both sides of the beam 50, with four Z-axis drive assemblies 501 being arranged on one side, and slide rails 503 being arranged on both sides of the beam 50. The inner side of the annular slider 504 is slidably connected to the slide rails 503 on both sides of the beam 50, and the outer side of the annular slider 504 is fixedly connected to multiple Z-axis drive assemblies 501. The beam 50 is provided with a beam X-axis drive assembly 505, which can drive the annular slider 504 to slide back and forth along the beam 50. Since the Z-axis drive assemblies 501 are distributed on both sides of the beam 50, such a layout enables the machine to make more full use of space and can perform work in a wider range. By driving the slider through the X-axis drive assembly, the eight Z-axis drive assemblies 501 can move synchronously and efficiently, realizing simultaneous processing of multiple stations, which greatly improves production efficiency.

[0028] When the workpiece is being processed, the first loading box 701 and the second loading box 702 are both full of materials, and the mounting seat cylinder 703 below them is in a retracted state. The first loading box 701 is located at the position of the loading conveyor belt 40. At this time, the loading and taking mechanism 70 takes the materials out of the first loading box 701 and puts them on the loading conveyor belt 40. For each piece put, the loading conveyor belt 40 moves forward by half the distance between the processing spindles 502. After eight pieces are put, the loading mechanism 70 moves forward by half the distance between the processing spindles 502. The conveyor belt 40 will go to a fixed material picking position and wait for the robot to pick up the materials. At this time, the loading and picking mechanism 70 will continue to pick up a piece and place it on the loading conveyor belt 40, and then absorb another piece in preparation. The robot X-axis drive component 603 and the robot Z-axis drive component 604 will move in coordination, and the robot suction cup 601 will absorb the eight pieces of raw materials on the loading conveyor belt 40. At this time, the first cylinder 602 and the second cylinder 609 of the two groups of robot suction cups 601 are both in a retracted state. The manipulator X-axis drive assembly 603 and the manipulator Z-axis drive assembly 604 cooperate to move and deliver the raw material to the four-side positioning fixture 301 on the first Y-axis drive assembly 20. At this time, the four-side positioning fixture 301 inside the first Y-axis drive assembly 20 stops at the same straight line position as the feeding conveyor belt 40. Then, the manipulator X-axis drive assembly 603 and the manipulator Z-axis drive assembly 604 cooperate to move and align the odd-array suction cups on the manipulator suction cup 601 with the four-side positioning fixture inside the lower side. Then, the first cylinder 602 extends out to place the raw material on the four-side positioning fixture 301. Then, the first cylinder 602 retracts, and the first Y-axis drive assembly 20 moves backward to place the outer The four-side positioning fixture 301 on the side stops at the same straight line position as the feeding conveyor belt 40, and then the robot X-axis drive component 603 and the robot Z-axis drive component 604 cooperate to move, align the even-group suction cups on the robot suction cup 601 with the outer four-side positioning fixture below, and then the second cylinder 609 extends out to place the raw material on the outer four-side positioning fixture 301, then the cylinder retracts, and then the first Y-axis drive component 20 cooperates with the X-axis drive component and the eight Z-axis drive components 501 to allow the processing spindle 502 to process the raw material thereon, and the robot repeats the loading action to load the two groups of four-side positioning fixtures 301 on the second Y-axis drive component 30.

[0029] When the raw material on the first Y-axis drive assembly 20 is processed, the X-axis drive assembly drives the eight Z-axis drive assemblies 501 to move rightward, and cooperates with the processing spindle 502 on the second Y-axis drive assembly 30 to process the raw material on the second Y-axis drive assembly 30. At the same time, the first Y-axis drive assembly 20 moves forward to make the outer four-side positioning fixture 301 position and the feeding conveyor belt 40 in the same straight line position, and the manipulator X-axis drive assembly 603 and the manipulator Z-axis drive assembly 604 cooperate to move, align the even-numbered suction cups on the manipulator suction cup 601 with the four-side positioning fixture on the outer side of the lower side, and then the second cylinder 609 extends out to take out the finished material on it. After taking it out, the second cylinder 609 retracts, and then The first Y-axis drive assembly 20 continues to move forward, so that the position of the inner four-side positioning fixture 301 is in the same straight line position as the feeding conveyor belt 40, and the manipulator X-axis drive assembly 603 and the manipulator Z-axis drive assembly 604 cooperate to move, align the odd-array suction cups on the manipulator suction cup 601 with the four-side positioning fixture on the inner side of the lower side, and then the first cylinder 602 extends out to take out the finished material on it. After taking it out, the first cylinder 602 retracts, and then the manipulator X-axis drive assembly 603 and the manipulator Z-axis drive assembly 604 cooperate to move, put the finished material on the manipulator suction cup 601 into the material receiving box 102, and then feed the four-side positioning fixture 301 on the first Y-axis drive assembly 20, and repeat this cycle.
