Description

Technical Field

[0001] The utility model relates to the field of auxiliary heat dissipation mechanisms, in particular to a turret auxiliary heat dissipation mechanism for a sorter. Background Technique

[0002] The turret type test sorter is a chip test device with a direct drive rotary motor (hereinafter referred to as DD motor) as the center and each module arranged evenly in a ring. The vacuum suction nozzles installed on the turret transport the chips to be tested to each module station.

[0003] Due to the special working conditions of high response, high rigidity and high-speed positioning of the turret type sorter, the DD motor needs to start and stop frequently at each station. As the production speed (UPH) of the turret increases, the load rate of the DD motor also increases accordingly. The accumulated heat generated by frequent start and stop and long-term operation under high load causes the temperature of the DD motor to rise. When the temperature of the DD motor exceeds the limit, overheat protection will be triggered, and the DD motor will stop rotating or operate at a reduced frequency.

[0004] Most of the DDRs of the existing turret type sorters on the market are passive heat dissipation and are protected by a semi-closed protective cover, with poor heat dissipation effect and long cooling time. There is an urgent need in the market to upgrade and transform old machines to improve production capacity. In order to minimize the upgrade and transformation cost as much as possible while meeting the requirements, a turret auxiliary heat dissipation mechanism for a sorter is proposed, which can be directly installed on the auxiliary heat dissipation mechanism of the equipment to expand the heat dissipation area of the DD motor and change the passive heat dissipation mode to active heat dissipation. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a turret auxiliary heat dissipation mechanism for a sorter to solve the technical problems of poor heat dissipation effect and long cooling time of the existing turret type sorters.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A turret auxiliary heat dissipation mechanism for a sorter, including a bottom plate and a sorter main body. The top surface of the bottom plate is provided with the sorter main body, and a protective cover is semi-wrapped at the top end of the sorter main body. A fan mounting plate is arranged on the top surface of the sorter main body, and a plurality of exhaust fans are installed on the fan mounting plate. A group of heat dissipation fins is arranged to wrap the motor part of the sorter main body, and a heat conduction layer is arranged between the heat dissipation fins and the motor.

[0007] By adopting the above technical solution, during use, the exhaust fans drive the air to flow, pass through the heat dissipation fins, and quickly take away the heat of the motor through the air by forced convection. The heat conduction layer makes the heat dissipation fins fit more closely with the motor.

[0008] The present utility model is further configured such that the heat dissipation fin plate is composed of an arc plate and fins, and the fins are evenly distributed radially on the outer surface of the arc plate.

[0009] By adopting the above technical solution, the radially arranged fins can cooperate with the rotation effect of the fan.

[0010] The present utility model is further configured such that the cross-section of the fin is an isosceles trapezoid, and the included angle between the two side surfaces of the fin is six degrees.

[0011] By adopting the above technical solution, the air flow can be effectively promoted, and the heat dissipation effect can be enhanced.

[0012] The present utility model is further configured such that the top surface of the protective cover is provided with heat dissipation holes that cooperate with the exhaust fan.

[0013] By adopting the above technical solution, it is convenient for the hot air to be discharged.

[0014] The present utility model is further configured such that the exhaust fan adopts an axial flow fan.

[0015] By adopting the above technical solution, the wind force is greater and the heat dissipation effect is better.

[0016] The present utility model is further configured such that the thicknesses of both the arc plate and the fins are greater than four millimeters, and the materials of the arc plate and the fins are 6063 aluminum alloy.

[0017] By adopting the above technical solution, it can better withstand the impact of instantaneous heat load, and the 6063 aluminum alloy has better heat conduction effect.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] The present utility model greatly improves the heat dissipation performance by arranging a heat dissipation fin plate outside the motor and an exhaust fan inside the protective cover, driving the air flow through the exhaust fan, and dissipating heat by forced convection. It improves the ability to withstand the impact of instantaneous heat load, reduces the processing requirements and costs of the heat dissipation fins by cooperating with specially designed heat dissipation fins and thermal interface materials, and has excellent heat conduction performance and good heat dissipation effect. It can be directly installed on the existing machine platform, reducing the cost of transformation and upgrading. After improving the heat dissipation ability, the turret can be adapted to a higher speed UPH to improve production capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0025] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0026] A turret auxiliary heat dissipation mechanism for a sorter, as Figures 1-3 shown, includes a bottom plate 1 and a main body 2 of the sorter. The top surface of the bottom plate 1 is provided with the main body 2 of the sorter, and the top end of the main body 2 of the sorter is semi-wrapped with a protective cover 3. A fan mounting plate 4 is provided on the top surface of the main body 2 of the sorter, and a plurality of exhaust fans 5 are installed on the fan mounting plate 4. The exhaust fans 5 adopt axial fans. During heat dissipation, the exhaust fans drive the air to flow, and the device is dissipated by forced convection. Heat dissipation holes 8 matching the exhaust fans 5 are opened on the top surface of the protective cover 3, and the hot air is discharged from the protective cover 3 through the heat dissipation holes 8. A group of heat dissipation fin plates 6 are wrapped around the motor part of the main body 2 of the sorter. The heat dissipation fin plates 6 are composed of arc plates and fins. The fins are evenly distributed radially on the outer surface of the arc plate, and a heat conduction layer 7 is provided between the heat dissipation fin plates 6 and the motor, so that the heat dissipation fin plates 6 are more closely attached to the motor and the heat conduction effect is better.

[0027] Among them, considering that the DD motor is longitudinally installed and the thermal interface material needs to be arranged in a cylindrical surface. To ensure the stability of use, the heat conduction layer 7 adopts a solid thermal interface material, which needs to have good surface wettability, high flexibility, that is, it can generate a high deformation amount under a low pressure, reduce mechanical stress, extremely low volatility, avoid affecting the chip products to be sorted and tested, and an insulating material with a high volume resistivity, such as a thermal conductive silica gel pad.

[0028] Furthermore, to effectively promote air flow and enhance the heat dissipation effect, the included angle between the two side surfaces of the fins is controlled at six degrees, and the thickness gradually thins from one end close to the arc plate to the other end, so that its cross section is trapezoidal.

[0029] To withstand the impact of instantaneous heat load, the thicknesses of both the arc plate and the fins are greater than four millimeters, and the material is selected as 6063 aluminum alloy, which has a high thermal conductivity and better heat dissipation effect.

[0030] Although embodiments of the present utility model have been shown and described, the specific embodiments are merely explanations of the present utility model and not limitations thereof. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
