Technical Field

[0001] The utility model belongs to the technical field of hot air drying of resistor substrates, in particular to hot air drying equipment for resistor substrates. Background Art

[0002] Thin film resistors generally use ceramic, glass or silicon as substrates, and are cleaned and polished to ensure the flatness and cleanliness of the substrate surface.

[0003] After cleaning, the resistor substrate needs to be dried to ensure subsequent processing. During the drying process, the cleaned substrate is placed on a filter belt and transported by a motor while being blown by a hot air blower to achieve the purpose of drying. After drying, it needs to be taken out one by one manually, which is cumbersome and increases the time for taking out. For this reason, we propose a hot air drying equipment for resistor substrates to solve the above-mentioned shortcomings. Utility Model Content

[0006] Preferably, the adjustment structure includes a threaded bolt sliding inside the adjustment groove, the bottom of the threaded bolt is fixedly connected to the top of the vacuum suction cup, the top thread of the threaded bolt surface is connected to a nut, and the bottom of the nut is tightly fitted with the top end face of the horizontal plate.

[0007] Preferably, there are multiple vacuum suction cups, and the tops of the vacuum suction cups are connected to an external vacuum pump through a connecting pipe.

[0008] Preferably, both ends of the rear side of the top of the horizontal plate are fixedly connected to guide rods, the surface of the guide rods is slidably connected to the inner surface of the movable plate, and the top of the guide rods is fixedly connected to a limiting handle.

[0009] Preferably, the farthest end of the threaded sleeve when the outer surface of the threaded rod is threadedly rotated is located on the left side of the support frame.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model places the resistor substrate to be dried on the surface of the filter belt, and drives the filter belt to transmit through the stepper motor. When the substrate passes the corresponding position of the hot air box, the hot air generated by the hot air blower is blown onto the upper and lower surfaces of the substrate through the hot air box, thereby achieving the drying effect. Under the transmission, when passing under the vacuum suction cup, the movable plate moves downward, so that the movable plate drives the cross plate to move downward, thereby adsorbing the substrate through the vacuum suction cup. At the same time, the servo motor drives the threaded rod to rotate, and under the rotation of the threaded rod, the threaded sleeve is driven to rotate, thereby driving the movable plate to move, and the vacuum suction cup connected to the bottom of the movable plate is moved to the upper position of the external collection box. At the same time, through the adjustment structure, the position of the vacuum suction cup can be adjusted according to the situation of the substrate. By setting the above structure, convenient material removal can be achieved, replacing the manual material removal method, thereby reducing the material removal time.

[0012] 2. The utility model adjusts the position of the vacuum cup by sliding the threaded bolt on the inner surface of the adjustment groove and tightening it with a nut. At the same time, the number of vacuum cups can be increased or decreased according to the conditions of the substrate.

[0013] 3. The utility model provides a guide rod that is slidably connected to the inner surface of the movable plate, which can support the horizontal plate and guide the horizontal plate to move up and down;

[0014] 4. The present invention arranges the farthest end of the threaded sleeve on the left side of the support frame when the thread on the outer surface of the threaded rod is rotated, thereby avoiding the situation where the substrate adsorbed by the vacuum suction cup cannot be placed in the collection box due to insufficient displacement caused by the rotation.

The resistor substrate to be dried is placed on the surface of the filter belt 2, and the filter belt 2 is driven by the stepping motor to drive.

[0024] Working principle: When the present invention is used, the resistance substrate to be dried is placed on the surface of the filter belt 2, and the filter belt 2 is driven by the stepper motor to transmit. When the substrate passes the corresponding position of the hot air box 4, the hot air generated by the hot air blower 3 is blown onto the upper and lower surfaces of the substrate through the hot air box 4. Since it is arranged at the upper and lower positions of the filter belt 2, the drying effect is achieved. Under the transmission, when it passes under the vacuum suction cup 11, the movable plate 8 moves downward, so that the movable plate 8 drives the cross plate 10 to move downward, thereby adsorbing the substrate through the vacuum suction cup 11. At the same time, the servo motor 5 drives the threaded rod 6 to rotate. Under the rotation of the threaded rod 6, the threaded sleeve 7 is driven to rotate threadedly, thereby driving the movable plate 8 to move, and the vacuum suction cup 11 connected to the bottom of the movable plate 8 is moved to the upper position of the external collection box. The position of the vacuum suction cup 11 is adjusted to achieve convenient material removal.

At the same time, the number of vacuum suction cups 11 can also be increased or decreased according to the situation of the substrate.
