Description

Technical Field

[0001] The invention relates to the technical field of processing and collecting equipment, and in particular to a grading device for cutting workpieces. Background Art

[0002] At present, in the process of machine tool processing, CNC machining center is a highly automated multifunctional CNC machine tool with tool magazine and automatic tool changing device. After the workpiece is clamped once on the CNC machining center, it can complete multiple processes on more than two surfaces, and has multiple tool changing or tool selection functions, thus greatly improving production efficiency.

[0003] With the continuous optimization of functions, the number of workpieces that can be processed by a CNC machine tool is gradually increasing, including workpieces of different sizes and models. Therefore, a CNC machine tool is efficiently produced and after cutting the workpiece, batches of workpieces are continuously processed from the production line. In the subsequent batch workpiece handling operations, on the one hand, it is necessary to ensure the overall handling of the batch workpieces, that is, the batch workpieces are kept neatly and regularly distributed during the handling process, and the batch workpieces will not be confused during the handling. On the other hand, the batch handling operation is required to be convenient and efficient. In the process, manual grading and classification is inefficient and has large errors (especially for workpieces that are highly similar but are actually cut in different sizes and models). At the same time, arbitrarily throwing and placing the workpieces randomly can easily cause damage to the workpieces. Summary of the invention

[0027] See also Figure 1-5 , a grading device for cutting a workpiece, comprising:

[0028] A frame 1 is provided, in which a grading mechanism 2 for automatically sorting cutting workpieces is installed. A shell 101 is also fixedly installed on the frame 1 to reduce the interference of the external environment on the grading mechanism 2, thereby ensuring the accuracy of grading. An observation port is also provided on the shell 101, and an openable and closable observation window is installed at the observation port. The operation of the grading mechanism 2 can be checked by opening the observation window. A signal light 103 for monitoring the operation status of the grading mechanism 2 is also provided on the frame 1. When the grading mechanism 2 operates normally, the signal light 103 is green, and when the operation is abnormal, the signal light 103 is red, thereby prompting the workers to handle it. A power supply 104 for supplying power to various electrical devices is also installed on the frame 1.

[0029] Rating Agency 2, see Figure 3The grading mechanism 2 includes: an electric glass turntable 201, an image collector 203, and the electric glass turntable 201 is installed inside the frame 1. In this embodiment, the electric glass turntable 201 rotates counterclockwise. Three brackets 204 are fixedly installed on the frame 1 in sequence along the rotation direction of the electric glass turntable 201. They are arranged in the order of the cutting workpieces passing through, namely, the first bracket 2041, the second bracket 2042 and the third bracket 2043. Among them, an infrared transmitter 202 is installed on the first bracket 2041. The cutting workpiece entering the electric glass turntable 201 is marked by the infrared transmitter 202 to facilitate subsequent grading. There are two image collectors 203, and the two image collectors 203 are respectively installed on the second bracket 2042 and the third bracket 2043. Among them, the infrared transmitter 202 is installed on the first bracket 2041. The image collector 203 on the second bracket 2042 is located above the electric glass turntable 201, and is used to collect image information of the front side of the cutting workpiece. The image collector 203 installed on the third bracket 2043 is located below the electric glass turntable 201, and is used to collect image information of the back side of the cutting workpiece. By collecting images of the front and back sides of the cutting workpiece, the grading deviation caused by visual blind spots is reduced, thereby ensuring accurate grading. The image collector 203 can use a CCD industrial camera. Furthermore, an annular fill light 205 corresponding to the image collector 203 is also installed on the second bracket 2042 and the third bracket 2043, and the image collector 203 is coaxially arranged with the annular fill light 205. The annular fill light 205 is used to fill light for the shooting process, thereby ensuring clarity of image information and thus ensuring accurate grading.

[0030] Furthermore, a number of blowers 206 corresponding to the discharge positions of the electric glass turntable 201 and grading pipes 207 corresponding to the blowers 206 are sequentially installed on the frame 1; when in use, the appearance information of the cut workpiece is collected by the image collector 203, and the collected appearance information is transmitted to the central control system, and the image information is analyzed and graded by the central control system, and the results are transmitted to the controller 102. When the graded cut workpiece rotates to the corresponding grading pipe 207 mouth, the controller 102 controls the opening of the corresponding blower 206, so as to blow the cut workpiece into the grading pipe 207 for unified collection.

[0031] Conveying mechanism 3, see Figure 4The discharging end of the conveying mechanism 3 is connected to the feeding position of the electric glass turntable 201, and its feeding end is connected to the vibration disk feeder 4. The conveying mechanism 3 includes: a conveyor belt 301, a motor 303, and a conveying frame 304. Both ends of the conveying frame 304 are rotatably installed with a rotating shaft 302, one of which is connected to the motor 303 through a belt drive. The motor 303 is fixedly installed on the conveying frame 304, and a roller is fixedly connected to the rotating shaft 302. The conveyor belt 301 is wound around two rollers together. The discharging end of the conveyor belt 301 is connected to the feeding position of the electric glass turntable 201, and its feeding end is connected to the vibration disk feeder 4. The vibration disk feeder 4 is a prior art, and its principle is: there is a vibrator 402 under the loading disk 401, and the loading disk 401 can be vibrated in the vertical direction through the vibrator 402. The loading disk 401 is driven by the inclined spring sheet to perform torsional vibration around its vertical axis, so that the cut workpiece inside it rises along the spiral track.

[0032] When the motor 303 is started, the conveyor belt 301 can be driven to rotate, thereby conveying the cut workpiece to the electric glass turntable 201. Further, when the cut workpiece is relatively neat in shape, it can be automatically fed by the vibrating plate feeder 4. When the cut workpiece is irregular in shape and the vibrating plate feeder 4 cannot be automatically fed, the worker can directly place the cut workpiece on the conveyor belt 301 for manual feeding.

[0033] A power supply for supplying power to various electrical devices is installed on the rack 1 .

[0034] Specific working process:

[0035] The cutting workpiece is conveyed to the electric glass turntable 201 by the conveying mechanism 3. As the electric glass turntable 201 rotates, the cutting workpiece first passes through the first bracket 2041, and is marked by the infrared transmitter 202. Then, the cutting workpiece passes through the second bracket 2042, and the image collector 203 collects the front appearance information of the cutting workpiece. Then, the cutting workpiece passes through the third bracket 2043, and the image collector 203 collects the back appearance information of the cutting workpiece. The collected image information is transmitted to the central control system for analysis and grading, and the result is transmitted to the controller 102. When the graded cutting workpiece rotates to the mouth of the corresponding grading pipe 207, the controller 102 controls the opening of the corresponding blower 206, so as to blow the cutting workpiece into the grading pipe 207 for unified collection.
