Description

[Technical field]

[0001] The utility model relates to the technical field of DD motors, in particular to a high-speed DD motor heat dissipation shell. [Background Technology]

[0002] DD motor, also known as DD direct drive motor, is a direct drive motor including torque motor and linear motor. Compared with traditional motors, the large torque of DD motor enables it to be directly connected to the motion device, eliminating mechanisms such as reducers, gear boxes, pulleys, etc., so it is called a direct drive motor.

[0003] The die bonder is a key device used in the semiconductor packaging process. Its main function is to firmly connect the electrical connection points (solder points) between the chip (wafer) and the packaging substrate to achieve electrical connection and physical support. The die bonder can place chips and components at high speed and high precision, and achieve key steps such as positioning, alignment, flip-chip, and continuous mounting. This puts higher requirements on the high-speed and high-precision operation of the motor. The large amount of heat generated by the motor during high-speed operation needs to be discharged in time so that the motor can maintain high-speed and high-precision operation for a long time. [Contents of the utility model]

[0004] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a high-speed DD motor heat dissipation housing with high heat dissipation efficiency and long service life, so that the heat generated by the motor during high-speed operation can be discharged in time, and the motor can be guaranteed to run continuously for a long time at high speed.

[0005] In order to achieve the above-mentioned purpose, a high-speed DD motor heat dissipation shell is designed, including a heat dissipation shell 1, a shell cover 2 and a heat dissipation fan 3. The outer wall of the heat dissipation shell 1 is radially provided with radial heat dissipation grooves 101, and the radial heat dissipation grooves 101 are annular grooves. At least two radial heat dissipation grooves 101 are provided and are arranged at intervals from top to bottom. The outer wall of the heat dissipation shell 1 is axially provided with axial heat dissipation grooves 102. The axial heat dissipation grooves 102 are arranged along the axial direction and extend from the top to the bottom of the heat dissipation shell 1. The shell cover 2 is installed on the outside of the heat dissipation shell 1 by bolts. The heat dissipation fan 3 is installed on the shell cover 2. The radial and axial heat dissipation grooves 101 and the axial heat dissipation grooves 102 form a heat dissipation channel that runs radially and axially up and down between the shell cover 2 and the heat dissipation shell 1, so that the heat dissipation efficiency is high, which can ensure that the motor can run continuously for a long time at a high speed.

[0006] Furthermore, two cooling fans 3 are provided, and the two cooling fans 3 are installed symmetrically on the top of the outer shell cover 2. The two cooling fans 3 are used to run simultaneously to discharge the heat of the heat dissipation outer shell 1 to the outside, thereby further improving the heat dissipation effect.

[0007] Furthermore, the radial heat dissipation grooves 101 and the axial heat dissipation grooves 102 are arranged crosswise in a vertical and horizontal manner, and the cross-sections of the radial heat dissipation grooves 101 and the axial heat dissipation grooves 102 are both rectangular, which is easy to process and can be mass-produced.

[0008] Furthermore, at least two axial heat dissipation slots 102 are provided, and the at least two axial heat dissipation slots 102 are evenly spaced along the circumferential direction, so as to achieve the expected heat dissipation effect when used in conjunction with the radial heat dissipation slots 101 .

[0009] Furthermore, an output hole 103 is provided on the top surface of the heat dissipation shell 1, a coil is installed inside the heat dissipation shell 1, a cover 104 is detachably installed on the top of the heat dissipation shell 1, a heat dissipation copper tube is provided inside the heat dissipation shell 1, the heat dissipation copper tube is sleeved on the outer wall of the coil, both ends of the heat dissipation copper tube pass through the heat dissipation shell 1, and are connected to the heat sink arranged on the inner wall of the heat dissipation shell 1, thereby accelerating the heat dissipation inside the heat dissipation shell 1 and avoiding damage caused by overheating of the coil inside the heat dissipation shell 1.

[0010] Furthermore, a shock-absorbing pad is fixedly connected to the bottom of the outer shell cover 2, and a fixing plate is fixedly connected to the bottom of the shock-absorbing pad. Through holes are provided on the shock-absorbing pad and the fixing plate, and bolts are penetrated in the through holes. The shock-absorbing pad and the fixing plate are installed as a whole through bolts and nuts, so as to reduce vibration during operation and extend the service life of the DD motor. This solves the problem that most current motor heat dissipation shells have simple structures, are rigidly connected to other equipment during installation, have poor shock-absorbing effects, cause mutual collisions between components, and make loud noises, which in turn cause certain destructive force on the DD motor.

[0011] Furthermore, the surface of the outer shell cover 2 is coated with a corrosion-resistant coating, which is a zinc-nickel alloy coating, so that the motor shell has good corrosion resistance and extends the service life of the motor shell.

[0012] Compared with the prior art, the utility model has a novel and simple structure and a reasonable design. By respectively processing radial heat dissipation grooves and axial heat dissipation grooves in the radial and axial directions of the heat dissipation shell, a heat dissipation channel that passes through radially and axially up and down is formed between the shell cover and the heat dissipation shell through the radial heat dissipation grooves and the axial heat dissipation grooves. At the same time, two heat dissipation fans are installed on the shell cover. The two heat dissipation fans are operated simultaneously to discharge the heat of the heat dissipation shell to the outside to achieve efficient heat dissipation, thereby achieving high heat dissipation efficiency and long service life, so that the heat generated by the motor during high-speed operation is discharged in time, ensuring that the motor can run continuously for a long time at a high speed; in addition, by installing a heat dissipation copper tube inside the heat dissipation shell, and both ends of the heat dissipation copper tube pass through the heat dissipation shell and are connected to the heat sink, the heat dissipation of the inside of the heat dissipation shell is accelerated, and the damage caused by overheating of the coil inside the heat dissipation shell is avoided; in addition, the utility model fixes a shock-absorbing pad at the bottom of the shell cover to reduce vibration during operation, thereby extending the service life of the DD motor; and a zinc-nickel alloy plating layer is coated on the surface of the shell cover, so that the DD motor shell has a good corrosion resistance effect, further extending the service life, and is worthy of popularization and application.
