Description

Technical Field

[0001] The present invention relates to the technical field of motor scrapping methods, and in particular to a method and system for scrapping a motor stator assembly by weight proportion. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Since the era of electrification, motors have been widely used in equipment in various fields and in the field of new energy vehicles due to the convenience of electrical energy. In order to meet different production needs, motors of different types have been produced, but any motor at least includes a stator, a rotor, a coil wound around the stator, and a casing that encapsulates the stator and rotor.

[0003] Since motors are widely used in various fields of production and life, when equipment or new energy vehicles expire and are scrapped, a large number of scrapped motors will be generated at the same time. These motors contain components such as copper coils and silicon steel sheets, which have high recycling value. Due to the variety of motor types, the existing motor disassembly and recycling lines are not highly automated, and a large number of processes need to be completed manually by workers, which not only requires a large amount of manpower, but also has low disassembly efficiency.

[0004] A Chinese invention patent application entitled "Method for Disassembling Scrapped Motors" with the patent number "CN110311515A" proposes a method for disassembling scrapped motors, which includes the following steps: S1: pretreatment, cutting the bottom surface of the scrapped motor into a plane; S2: cutting the shell of the scrapped motor; S3: disassembling the shell to obtain a combination of a stator, a rotor and a coil; S4: disassembling the rotor to obtain a combination of a stator and a coil; S5: crosscutting the combination of a stator and a coil to separate the stator and the coil. This method can improve the disassembly efficiency of scrapped motors, improve the degree of mechanization and automation in the entire disassembly process, and reduce the labor intensity of workers. However, this is more for recycling and disassembly companies. Recycling and disassembly companies need to completely disassemble the motor, especially the motor stator, and completely decompose it according to different materials to achieve the maximum recycling effect. However, for manufacturing companies, they only need to obtain the weight details of each component of the scrapped motor stator and completely disassemble the motor stator into the stator core, copper wire winding, etc., that is, completely disassemble the motor stator according to the above method and then obtain the weight details of each part. However, there are problems such as investment in cutting equipment, long labor time required for disassembly, high labor intensity, cumbersome operation process and low disassembly efficiency, which is very unreasonable for manufacturing companies. Summary of the invention

[0027] The advantages of the present application are as follows: 1.

It only needs to obtain the specifications and models of the motor stator assembly and the corresponding weight to obtain the weight proportion and actual weight of the individual components of the motor stator assembly. The stator assembly can be scrapped as a whole without being disassembled, thus avoiding or reducing the input of special equipment, tooling and manpower, and improving the scrapping efficiency of the stator assembly. For production enterprises, it can reduce a large amount of manpower and the input of special disassembly equipment, and optimize the scrapping process;

[0028] 2. The preliminary disassembly of this application is to remove the peripheral components of the motor stator assembly.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] The present application relates to a method for scrapping a motor stator assembly by weight percentage. The method of the present application does not require complete disassembly of the motor stator assembly, and can determine the actual weight of each component based on the total weight of the motor stator assembly and the weight percentage of each component. In fact, the actual weight of each component of the motor stator assembly is determined, and then a statistical table is formed based on this information, which is convenient for subsequent scrapping of the motor stator assembly directly through the statistical table. The entire scrapping does not require complete disassembly of the motor stator assembly. For production enterprises, there is no need to build large-scale special disassembly equipment for the scrapped motor stator assembly, nor is there a need to invest a lot of manpower and material resources to specifically carry out the disassembly of the motor stator assembly. The equipment investment and personnel investment are greatly reduced, which improves the scrapping efficiency of the motor stator assembly and has great promotion value.

[0041] Specifically, Figure 1 As shown, a method of using weight ratio to scrap a motor stator assembly in the present application includes the following steps:

[0042] S1. Preliminary disassembly of the scrapped motor stator assembly;

[0043] The initial disassembly is to remove the peripheral structure of the motor stator assembly to be scrapped. This step of disassembly can be done with simple tools, so there is no need to configure large-scale special disassembly equipment for related operations;

[0044] S2. Determine the weight proportion of each component in the stator assembly of the motor to be scrapped based on the specifications and models of the stator assembly of the motor to be scrapped;

[0045] Each motor stator assembly to be scrapped has corresponding specifications and models, which can be obtained through the items used by the motor stator assembly to be scrapped. After obtaining the corresponding specifications and models, the weight proportion of each component in the motor stator assembly to be scrapped can be obtained;

[0046] S3, weighing the stator assembly of the motor to be scrapped, determining the actual weight of each component based on the weight of the stator assembly of the motor to be scrapped and the weight ratio of each component, and recording it in a statistical table;

[0047] After obtaining the weight of the motor stator assembly to be scrapped, the actual weight of each component can be obtained based on the weight proportion of each component in step S2. At this point, the relevant information required for the scrapping process has been collected, and the collected information can be filled in the statistical table to facilitate subsequent verification and scrapping.

[0048] S4. Verify the information filled in the statistical table to ensure that the information is correct and then scrap the stator assembly according to the scrap material management process;

[0049] After confirming that the statistical table is correct, the motor stator assembly to be scrapped can be scrapped based on the statistical table. The scrapping process only needs to count the actual weights of all corresponding components in the statistical table to obtain the weights of the same components in the corresponding number of motor stator assemblies. In fact, it is equivalent to obtaining the actual weight of the same material part. Subsequent decomposition and recycling can be verified and operated through this data.

[0050] In some embodiments of the present application, this embodiment optimizes the above-mentioned step S1. Specifically, the method for preliminary disassembly of the stator assembly of the scrapped motor in this embodiment is: removing the peripheral components of the stator assembly of the scrapped motor and retaining the three components of the stator copper wire winding, stator core and slot insulation of the stator assembly of the scrapped motor.

[0051] In fact, it is to use simple equipment, such as pliers, to disassemble or separate the copper bars, temperature sensors and other peripheral parts on the stator assembly of the scrapped motor as much as possible. Because the tools used are common tools, it is extremely easy to disassemble and does not require a lot of manpower and material resources.

[0052] Finally, what remains of the scrapped motor stator assembly are three components: the relatively complete stator copper wire winding, the stator core and the slot insulation. These three components are not easy to dismantle and decompose with simple tools, and these three components happen to correspond to three materials, namely silicon steel, copper and composite materials. Retaining these three components facilitates subsequent recycling.

[0053] In some other embodiments of the present application, this embodiment optimizes the above-mentioned step S2. Specifically, the method for determining the weight ratio of each component in the stator assembly of the motor to be scrapped is: based on the weight ratio information table of the components of the stator assembly of the motor of this model and specification, the weight ratio information of the three components of the stator copper wire winding, the stator core and the slot insulation is determined.

[0054] By using the project used by the motor stator assembly to be scrapped, it is actually to determine which project the motor stator assembly to be scrapped is used on, such as which vehicle model it is used on. The model and specification of the motor stator assembly to be scrapped can be determined by using the project situation. After determining the model and specification, the weight proportion information of the above three components in the motor stator assembly to be scrapped of the model and specification can be determined based on the corresponding information table. In actual use, other methods can also be used to obtain the information table, such as determining the specifications and model of the motor stator assembly to be scrapped by the structure of the motor stator assembly to be scrapped, and then looking up the corresponding information table.

[0055] In a further embodiment of the present application, this embodiment optimizes the above-mentioned step S3. Specifically, the stator assembly of the motor to be scrapped is first weighed. This weighing can be directly performed using an electronic scale to record the total weight of the stator assembly of the motor to be scrapped; then, the actual weight of the component is obtained based on the product of the weight of the stator assembly of the motor to be scrapped and the weight ratio of the corresponding component.

[0056] It can be calculated according to the following formula:

[0057] M i =M0*P

[0058] Where: M i ——The weight of a component of the stator assembly of the motor to be scrapped;

[0059] M0——Total weight of the motor stator assembly to be scrapped;

[0060] P——The weight proportion of a certain component of the stator assembly of the motor to be scrapped.

[0061] In a preferred embodiment of the present application, this embodiment optimizes the method of recording in the statistical table in the above step S3, and this embodiment optimizes the content recorded in the statistical table. This embodiment fills in the specifications and models of the stator assembly of the motor to be scrapped in the statistical table, fills in the weight percentage and actual weight of the stator core, i.e., silicon steel, fills in the weight percentage and actual weight of the stator copper wire winding, i.e., copper, fills in the weight percentage and actual weight of the slot insulation, i.e., the weight percentage and actual weight of the composite material.

[0062] Because the above-mentioned three components of stator copper wire winding, stator core and slot insulation correspond to three different materials respectively, what is actually recorded in the statistical table is the actual weight and weight proportion of silicon steel, copper and composite materials, which is also convenient for subsequent scrapping and decomposition and recycling operations.

[0063] The statistical table of this embodiment is not limited to the above information. For example, the statistical table shown in Table 1 may be used:

[0064] Table 1: Statistics of weight ratio of motor stator assembly components

[0065]

[0066] In actual operation: remove the peripheral parts of the motor stator assembly to be scrapped and retain the three components of the motor stator assembly to be scrapped, namely, the stator copper wire winding, the stator core and the slot insulation; determine the weight ratio information of the three components of the stator copper wire winding, the stator core and the slot insulation based on the weight ratio information table of the components of the motor stator assembly of this model and specification; weigh the motor stator assembly to be scrapped and record the total weight of the motor stator assembly to be scrapped; then, based on the multiplication of the weight of the motor stator assembly to be scrapped and the weight ratio of the corresponding components, The actual weight of the component is obtained by multiplying the product. In the statistical table, fill in the specifications and models of the motor stator assembly to be scrapped, fill in the weight percentage and actual weight of the stator core, i.e. silicon steel, fill in the weight percentage and actual weight of the stator copper wire winding, i.e. copper, fill in the weight percentage and actual weight of the slot insulation, i.e. composite materials; check the specifications and models of the motor stator assembly to be scrapped to ensure that the specifications and models filled in the statistical table completely correspond to the motor stator assembly to be scrapped; after ensuring that the information is correct, scrap the stator assembly according to the scrap material management process.

[0067] In addition, the present application also provides a system for scrapping a motor stator assembly by weight percentage, including a preliminary disassembly module, a weight percentage determination module, a statistical recording module and a verification module, wherein the preliminary disassembly module is used to perform preliminary disassembly of the motor stator assembly to be scrapped; the weight percentage determination module determines the weight percentage of each component in the motor stator assembly to be scrapped based on the specifications and models of the motor stator assembly to be scrapped; the statistical recording module determines the actual weight of each component based on the weight of the motor stator assembly to be scrapped and the weight percentage of each component, and records it in a statistical table; the verification module is used to verify the information filled in the statistical table, and after ensuring that the information is correct, the stator assembly is scrapped according to the scrap material management process.

[0068] The preliminary disassembly module is used to remove the peripheral components of the stator assembly of the motor to be scrapped and retain the three components of the stator copper wire winding, stator core and slot insulation of the stator assembly of the motor to be scrapped.

[0069] The weight ratio determination module determines the weight ratio information of the three components of the stator copper wire winding, the stator core and the slot insulation based on the weight ratio information table of the components of the motor stator assembly of the model and specification.

[0070] The statistical recording module includes an actual weight determination module and a statistical information module. The actual weight determination module obtains the actual weight of the component based on the product of the weight of the stator assembly of the motor to be scrapped and the weight ratio of the corresponding component; the statistical information module is used to fill in the specifications and models of the stator assembly of the motor to be scrapped, fill in the weight ratio and actual weight of the stator core, i.e., silicon steel, fill in the weight ratio and actual weight of the stator copper wire winding, i.e., copper, and fill in the weight ratio and actual weight of the slot insulation, i.e., composite material.

[0071] The verification module is used to verify the specifications and models of the motor stator assembly to be scrapped, ensuring that the specifications and models filled in the statistical table completely correspond to the motor stator assembly to be scrapped.
