Description

Technical Field

[0001] This utility model relates to the field of motor technology for dicing machines, specifically a DD motor for dicing machines. Background Technology

[0002] The grinding wheel dicing machine is a precision CNC device that integrates technologies such as water, air, electricity, high-speed air static pressure spindle, precision mechanical transmission, sensors, and automated control.

[0003] In grinding wheel dicing machines, a DD motor is typically used in conjunction with a vacuum suction fixture to hold the workpiece in place. When using a vacuum suction fixture, a ceramic insulating plate is usually placed on the DD motor rotor base, and a vacuum suction cup is mounted on the ceramic insulating plate. When using metal suction cups to hold wafers and other workpieces, static electricity can easily be generated due to friction. Static electricity may damage the electronic components on the wafers and other workpieces, affecting product performance and quality. When using suction cups made of other materials, the suction force is unstable and may be affected by factors such as flatness and vacuum pump performance, thus affecting the fixation and processing effect of the wafers and other workpieces.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This utility model provides a technical solution: a DD motor for a dicing machine, including a motor rotor seat 2 mounted on a motor base 3, a DD insulating plate 4 detachably mounted on the upper end face of the motor rotor seat 2, an adsorption channel for vacuum adsorption of workpieces provided in the inner cavity of the DD insulating plate 4, a stator core 8 fixedly connected to the motor base 3, coils 20 for driving the motor rotor seat 2 to rotate evenly arranged on the stator core 8, motor magnets 18 cooperating with the coils 20 evenly distributed in a ring on the inner wall of the motor rotor seat 2, an upper sealing sleeve 5 fixedly mounted in the middle of the DD insulating plate, a lower cover plate 13 fixedly connected to the lower end face of the motor base 3, a lower sealing sleeve 12 located in the middle of the inner cavity of the motor base 3 on the lower cover plate 13, and an oil seal 17 provided at the joint between the upper sealing sleeve 5 and the lower sealing sleeve 12.

[0025] This invention integrates the insulating pad and the DD motor, effectively reducing the transmission chain, achieving high transmission accuracy, and ensuring flatness during processing. Simultaneously, it effectively prevents conduction of the suction cup during blade contact height measurement. The overall structure is simplified, facilitating later maintenance and ensuring long-term stable operation. In practical applications, the DD insulating plate can be made of ceramic, giving it excellent adsorption properties and stability, ensuring that the material does not move or deform during processing, thereby improving processing accuracy and efficiency. Ceramic material is a good electrical insulator, effectively isolating conductors at different potentials and preventing current from flowing where it shouldn't, thus protecting the equipment and materials; it also provides robust mechanical support for the DD motor and other components, ensuring their stability during processing. Ceramic material has high temperature and corrosion resistance, maintaining its performance under harsh environmental conditions, thus extending the service life of the dicing machine and ensuring its normal operation and processing accuracy. The upper and lower sealing sleeves, in conjunction with oil seal 17, achieve excellent sealing within the motor. Traditionally, a suction cup with a ceramic insulating pad is mounted on a DD motor. However, due to machining accuracy errors in both the suction cup and the insulating pad, the combination further reduces the overall working accuracy of the dicing machine. Of course, the material of the DD insulating plate is not limited to ceramic; any insulating material that is strong, wear-resistant, and does not easily deform after processing can be used.

[0026] In this embodiment, a waterproof connector 1 is arranged on the motor base 3, and the DD insulation board 4 is fixedly installed on the upper end face of the motor rotor seat 2 by connecting screws 6. A reserved hole 7 is provided on the motor rotor seat 2.

[0027] In this embodiment, a reading head mounting plate 16 is detachably installed on the upper part of the motor base 3. A cross roller bearing 9 is arranged between the reading head mounting plate 16 and the motor rotor seat 2. A reading head 21 is arranged on the reading head mounting plate 16.

[0028] Reference Figure 5 and 6 As shown, in this embodiment, a code disk mounting plate 11 is fixedly connected to the middle of the DD insulating plate 4, and a glass code disk 10 is fixedly connected to the lower end face of the code disk mounting plate 11. The reading head 21 is used to cooperate with the glass code disk 10 to read values. The glass code disk 10 is a precision photoelectric encoder component, mainly used to measure physical quantities such as angle, speed, and position. Its working principle is mainly based on the light blocking and transmission effects and electronic signal processing technology. The glass code disk 10 has advantages such as high-precision positioning, good stability, low maintenance cost, and strong adaptability. Setting a code disk in the motor helps to improve the cutting quality and efficiency of the dicing machine, reduce production costs, and extend the equipment and its service life.

[0029] Reference Figure 6As shown, in this embodiment, an upper sealing ring 15 is arranged between the upper sealing sleeve 5 and the DD insulating plate 4, and a lower sealing ring 14 is provided between the lower cover plate 13 and the lower end face of the motor base 3. The upper and lower sealing rings 14 effectively ensure the sealing performance between the upper sealing sleeve 5 and the DD insulating plate 4, and between the lower cover plate 13 and the motor base 3, thereby improving the overall sealing performance of the motor.

[0030] Reference Figure 3 and 4 As shown, in this embodiment, high-temperature resistant epoxy boards 19 are provided on both the upper and lower end faces of the stator core 8, and the coil 20 is wound and arranged on the upper and lower high-temperature resistant epoxy boards 19. High-temperature resistant epoxy boards 19 are widely used in electrical insulation and structural support fields. Due to their excellent high-temperature resistance and electrical properties, they are often used in electrical equipment, electronic components, and mechanical parts in high-temperature environments to ensure stable operation and long-term use of the equipment. The motor magnet 18 is a permanent magnet, which can generate a stable magnetic field. In the DD motor, this magnetic field interacts with the magnetic field generated by the current passing through the stator coil 20, thereby generating rotational torque, driving the rotor to rotate, improving the motor's efficiency, stability, and torque output, while also adapting to high-temperature environments and optimizing control performance.
