[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1 to Figure 4, which is the first embodiment of the present invention, provides a glass bead grinding system, which includes a processing module 100, a weighing module 200, a burning module 300, a cleaning module 400 and an electrical control module 500. The processing module 100, the weighing module 200, the burning module 300 and the cleaning module 400 are arranged in the same closable space, and a manipulator is arranged inside the space. The processing module 100, the weighing module 200, the burning module 300, the cleaning module 400 and the manipulator can be controlled by the electrical control module 500 to ensure that no close human intervention is required during the operation of the entire system, thereby ensuring the safety of the operator and the safety of the environment.

[0035] Specifically, the processing module 100 is used to grind and screen the sample.

[0036] Furthermore, the processing module 100 includes a crusher 101, a grinder 102 and a sifter 103. The crusher 101 is used to crush the sample, the grinder 102 is used to grind the crushed sample, and the sifter 103 is used to sieve the ground sample powder.

[0037] Furthermore, the diameter of the sample transferred from the crusher 101 to the grinder 102 is less than 1 mm.

[0038] The glass bead sample is placed on the transmission track and can be transmitted to the confined space where the system is located to ensure the safety of personnel. After the glass bead sample is transmitted to the designated location, the control system operates the manipulator to place the glass bead sample in the crushing bowl, and the glass bead sample is crushed by the crusher 101. The crushed sample is sieved through a sieve to screen out particles with a diameter less than 1 mm, which is convenient for subsequent grinding of the sample. Particles larger than 1 mm are returned to the crusher 101 for further crushing.

[0039] The contact parts of the crusher 101 with the crushed object are made of polyetheretherketone, and the base is made of polytetrafluoroethylene plate. Polyetheretherketone has the effects of high temperature resistance, high strength, and high hardness, and can have good resistance to most chemical reagents. The base is made of polytetrafluoroethylene, which can reduce the wear of the crusher 101 during operation and improve work efficiency.

[0040] After crushing, the crushed particles in the crushing bowl are poured into the grinding bowl by operating the robot, the grinder 102 is turned on to grind the poured particles, and the glass particles are ground to the required particle size through the control system, and then the ground glass beads are moved to the screening machine 103 by controlling the robot.

[0041] Furthermore, a cover plate can be provided above the grinding bowl to prevent sample particles from falling out of the grinding bowl during the grinding process and causing environmental pollution. A rinse device can also be provided next to the grinder 102 to rinse the grinding bowl and grinding rod to ensure cleanliness after grinding. It can also prepare for the next grinding of samples of different materials to prevent reactions between different materials.

[0042] The grinder 102 is a micro-powder grinder, which can meet the grinding requirements and ensure the grinding particle size of the glass beads.

[0043] Adjust the screening requirements of the screening machine 103, screen the ground glass bead samples, place the qualified glass bead powder in a crucible, weigh the glass bead powder through the weighing module 200, select the appropriate weight, and control the robot to move the unqualified ones back to the grinder 102 for further grinding.

[0044] Furthermore, a grinding and screening integrated device can be used. When the device is ground, the glass beads ground to a specified degree can be directly screened through the screening net, which not only ensures the smooth operation of the device, but also speeds up the work efficiency and ensures the quality of screening.

[0045] Preferably, since the glass bead powder to be screened by the screening net is relatively small, in order to prevent the screening net from being blocked, the screening net can be set to vibrate screening to prevent it from being blocked.

[0046] The weighing module 200 is used to weigh the ground sample powder.

[0047] Specifically, the weighing module 200 includes a balance and a crucible. The crucible is placed above the balance and is used to hold sample powder to be weighed.

[0048] Furthermore, the weighing module 200 weighs a sample amount of 0.1 g ± 0.01 each time.

[0049] The powder in the crucible is weighed by a balance in the weighing module 200 , and 0.1 g±0.01 is weighed each time to meet the dosage required for the experiment.

[0050] A burning module 300 is used to burn the sample powder weighed by the weighing module 200;

[0051] Furthermore, the burning module 300 includes a heating furnace, and the heating furnace is a Muffle furnace.

[0052] The burning module 300 is controlled by a control system and cooperates with a robot to add corresponding units of acid and alkali reagents and glass bead powder into the crucible for melting. The burning temperature is about 600°C. After the burning is completed, the molten block is washed out in a beaker with hot deionized water, and the crucible is repeatedly rinsed to collect the washing liquid. An acid reagent is added to completely dissolve the molten block. After cooling, the solution is transferred to a volumetric flask to make up the volume as the test liquid.

[0053] The cleaning module 400 is used to clean the burning module 300 , the weighing module 200 and the processing module 100 .

[0054] Furthermore, the cleaning module 400 includes a cleaning box, a rinser and a waste liquid collection barrel. The waste liquid collection barrel is arranged below the cleaning box, and the rinser is installed inside the cleaning box.

[0055] The cleaning module 400 is used to clean the crucible, ensuring that no residual glass bead powder from burning remains in the crucible to affect the next burning and prevent it from affecting the accuracy of the entire system.

[0056] The electrical control module 500 is used to control the entire system.

[0057] Specifically, the electrical control module 500 includes a power distribution system and a PLC control system. The power distribution system adopts a TN system for power supply. The PLC control system is used to control the processing module 100, the weighing module 200, the burning module 300 and the cleaning module 400 in the system.

[0058] The power distribution system is a low-voltage power distribution system that can meet different power supply requirements such as equipment operation, heating, and control instruments, and ensure the normal use of the system during operation.

[0059] When controlling each module, it is divided into two parts: mechanical button control and touch screen command control. The mechanical button control is used to connect and disconnect the main power supply and the operation of each component; the touch screen command controls the operation of each component.

[0060] Select the appropriate PLC controller according to the number of I / O ports for control input and output, and select the corresponding touch screen. The touch screen and PLC communicate using the 485 communication protocol. Through the communication data line, the PLC obtains the control information sent by the touch screen and passes the control information to the actuator; at the same time, the touch screen obtains the sensor information transmitted back by the PLC.

[0061] like Figure 3 The schematic diagram of the installation position of the crusher 101, the grinder 102, the capping machine, the manipulator, and the balance is as follows: Figure 4 This is the installation distribution diagram of the burning module 300 and the cleaning module 400. Figure 3 and Figure 4The middle is a schematic diagram of the upper and lower layers, and the upper and lower layers are distributed in a stair-like manner to ensure that the operation of each module and the transfer of samples can be completed by the robot.

[0062] Example 2

[0063] Reference Figure 1 to Figure 4 , which is the second embodiment of the present invention, is different from the first embodiment in that it also includes a processing module 100 and a storage system 104, and the storage system 104 is used to store the sample powder after being sieved by the sieving machine 103.

[0064] Furthermore, the storage system 104 includes a sample bottle and a capping machine, and the capping machine is used to open or close the cap of the sample bottle.

[0065] The setting of the sample bottle and the capping machine can ensure the storage of the screened glass bead powder for easy use next time. The setting of the capping machine can realize the operations of opening, closing and replacing the cap of the sample bottle.

[0066] When screening the glass bead samples, take a certain amount of sample into the crucible and place it on a balance to weigh it. For the remaining screened powder, the cap of the sample bottle can be unscrewed by a capping machine, and then the excess powder can be put into the sample bottle, and the sample bottle is sealed by the capping machine, and then the sample bottle is placed on the sample rack for direct use next time.

[0067] The rest of the structure is the same as that of Example 1.

[0068] Example 3

[0069] Reference Figure 2 , which is the third embodiment of the present invention, is based on the first two embodiments and provides a glass bead grinding method, which comprises:

[0070] The sample is manually placed in a crusher 101 for crushing, and the crushed sample is sieved through a sieve and then transferred to a grinder 102;

[0071] The sample powder ground by the grinder 102 is moved to the sieving machine 103 for sieving;
