Description

Technical Field

[0002] Flat wire motors have the advantages of high slot fill rate and high power density, and are therefore increasingly widely used in the field of new energy electric drive. As a result, the quality control and production process requirements for motors are becoming increasingly higher. The motor stator paint dripping process is an important link in the motor production process, and the motor stator paint dripping filling rate will directly affect the insulation of the product.

[0023] The utility model discloses a paint dripping system for a motor stator.

[0024] The motor stator paint dripping system includes a paint dripping workbench, a paint dripping work frame is arranged on the paint dripping workbench, a temporary placement table is fixedly arranged on the paint dripping work frame and a tooling connector is installed, a tooling library is arranged inside the paint dripping workbench, and the tooling library is built into the paint dripping workbench in the form of a drawer, and the tooling library contains a plurality of tooling placement slots of different sizes, each tooling placement slot has a different size, and each tooling placement slot is used to place clamping tools of different sizes, and each clamping tool of different sizes is used to clamp and fix motor stators of different sizes during the paint dripping process. Tooling fixtures are arranged at the position of each tooling placement slot on the tooling library, and the tooling fixtures can be magnetic fixing rings, and the tooling fixtures are used to fix the clamping tools in the corresponding tooling placement slots. A camera module for collecting images of the motor stator is also arranged on the paint dripping workbench, and the camera module can be a high-definition camera.

[0025] On both sides of the temporary placement table on the paint dripping work stand, an infrared transmitting matrix and an infrared receiving matrix are installed respectively. Figure 1 The infrared transmitting matrix includes multiple infrared transmitting units, and the infrared receiving matrix includes multiple infrared receiving units corresponding to the positions of the multiple infrared transmitting units. When any infrared receiving unit receives the infrared signal emitted by the corresponding infrared transmitting unit, the infrared receiving unit outputs the same output voltage. The system also includes a voltage superposition module and a voltage comparison control module. The voltage superposition module is composed of multiple superposition resistors or multiple superposition capacitors. The infrared receiving matrix is ​​connected to the voltage superposition module, and the voltage superposition module is connected to the voltage comparison control module. The voltage comparison control module includes multiple voltage comparison units and multiple control units. The control unit is used to control the opening and closing of the tooling fixture. The number of voltage comparison units and control units is the same as the number of tooling placement slots. All voltage comparison units are preset with voltage thresholds of different sizes.

[0026] Each voltage comparison unit is connected to the tool fixing corresponding to the unique tool placement slot through a unique control unit, and the smaller the voltage threshold preset in the voltage comparison unit, the larger the size of the tool placement slot corresponding to the connected tool fixing. The specific correlation between the voltage threshold and the size of the corresponding tool placement slot is as follows: the larger the size of the tool placement slot, the larger the size of the clamping tool placed in the tool placement slot, the larger the size of the clamping tool, the larger the size of the motor stator that can be clamped and fixed by the clamping tool, and the larger the size of the motor stator, the more the motor stator can block the infrared signal emitted by the infrared emission matrix, thereby causing the superposition voltage output by the infrared receiving matrix through the voltage superposition module to be smaller, so the voltage threshold preset in the corresponding voltage comparison unit should also be smaller. And the tool placement slot is consistent with the corresponding clamping tool size, and the clamping tool is consistent with the corresponding motor stator size.

[0027] In summary, the implementation principles of the above implementations are:

[0028] When it is necessary to drip paint on motor stators of different sizes and models, the motor stators to be dripped with paint can be placed at a preset position on a temporary placement table according to a preset placement direction. At this time, the motor stators will block part or all of the infrared signals in the infrared emission matrix, thereby changing the superimposed voltage output by the infrared receiving matrix through the voltage superposition module, and comparing the superimposed voltage with the preset voltage threshold in each voltage comparison unit. If the superimposed voltage exceeds the voltage threshold in the voltage comparison unit, the voltage comparison unit will output a control signal to the control unit, and the control unit will open the corresponding tooling fixture after receiving the control signal. Since the voltage threshold is preset according to the size of the corresponding tooling placement slot, the tooling placement slot corresponding to the opened tooling fixture is placed with a clamping fixture of the appropriate size, thereby avoiding the mistake of replacing the clamping fixture of the inappropriate size when manually replacing the clamping fixture.

[0029] In one embodiment, the motor stator paint dripping system further includes a master control module, all control units are connected to the master control module, and the master control module is used to limit the maximum number of control units that are simultaneously opened to 1. The master control module can be composed of multiple relays. Through the setting of the master control module, it can be avoided that multiple tooling fixtures are opened at the same time, resulting in manual mistakenly taking inappropriate clamping tools.

[0030] In one embodiment, referring to Figure 2 The infrared transmitting unit includes an infrared transmitter D1, a resistor R1 and a variable resistor RP1. The infrared transmitter D1 is connected to a DC power supply. The infrared transmitter D1, the resistor R1 and the variable resistor RP1 are connected in series to ground. The infrared receiving unit includes an infrared receiver RG, a resistor R2, a resistor R3, a resistor R4, a resistor R5 and an operational amplifier A1. One end of the infrared receiver RG and the resistor R2 are connected in parallel to the non-inverting input end of the operational amplifier A1. The other end of the infrared receiver RG is connected to a DC power supply. The other end of the resistor R2 is grounded. One end of the resistor R3 is connected to the inverting input end of the operational amplifier A1. One end of the resistor R4 and the resistor R5 are connected in parallel to the other end of the resistor R3. The other end of the resistor R4 is connected to a DC power supply. The other end of the resistor R5 is grounded. The output end of the operational amplifier A1 is connected to the voltage superposition module.

[0031] like Figure 2 As shown, the infrared transmitting unit transmits an infrared signal through the infrared transmitter D1. If the corresponding infrared receiving unit receives the infrared signal through the infrared receiver RG, when the infrared receiver RG receives the infrared signal, it will output a preset standard voltage through the operational amplifier A1. The preset standard voltage is related to the resistance values ​​of the resistors R4 and R5. If the corresponding infrared receiving unit does not receive the infrared signal, the voltage output by the infrared receiving unit is 0. The voltage superposition module can superimpose the standard voltages output by all infrared receiving units and output them. The larger the superimposed voltage, the smaller the stator size of the motor.

[0032] In one embodiment, the voltage comparison control module further includes a plurality of delay output units, and the output end of the voltage superposition module is connected to all the delay output units. Figure 3 The delay output unit is connected to the voltage comparison unit, and the delay output unit is used to delay the voltage output by the voltage superposition module to the corresponding voltage comparison unit, and the larger the voltage threshold preset in the voltage comparison unit, the smaller the output delay preset in the corresponding delay output unit. Through the setting of the delay output unit, the voltage output by the voltage superposition module can be sequentially input to the voltage comparison units with voltage thresholds from large to small.

[0033] In one embodiment, Figure 3As shown, the voltage comparison unit includes a voltage comparison circuit and a signal amplification circuit, the input end of the voltage comparison circuit is connected to the corresponding delay output unit, the output end of the voltage comparison circuit is connected to the input end of the signal amplification circuit, and the output end of the signal amplification circuit is connected to the corresponding control unit. The voltage comparison circuit includes a resistor R6, a resistor R7 and a voltage comparator A2, the non-inverting input end of the voltage comparator A2 is connected to the corresponding delay output unit, one end of the resistor R6 and the resistor R7 are connected in parallel to the inverting input end of the voltage comparator A2, the other end of the resistor R6 is grounded, and the other end of the resistor R7 is connected to a DC power supply. The signal amplification circuit includes a resistor R8, a resistor R9, a resistor R10, a resistor R11 and an operational amplifier A3, the output end of the voltage comparison circuit is connected to the inverting input end of the operational amplifier A3 through the resistor R8, one end of the resistor R11 is grounded, the other end of the resistor R11 is connected to the non-inverting input end of the operational amplifier A3, one end of the resistor R9 is connected to the inverting input end of the operational amplifier A3, the other end of the resistor R9 is connected to the output end of the operational amplifier A3 through the resistor R10, and the output end of the operational amplifier A3 is connected to the corresponding control unit. When the voltage output by the voltage superposition module exceeds the voltage threshold preset in the voltage comparison circuit, the voltage comparator A2 will output a control voltage, and the control voltage is amplified by the signal amplification circuit and output to the control unit, thereby opening the corresponding tooling fixture through the control unit.
