Abstract
The invention discloses a protection device used for an integrated circuit product before plastic package. The protection device comprises a ball screw (2) and a motor (1) controlling the ball screw to rotate, wherein a brake device is arranged at one end, far away from the motor (1), of the ball screw (2). According to the protection device, under the condition that the manufacturing cost of the product is minimized, a structural form that the ball screw is combined with the brake device is adopted, and the brake device can prevent the ball screw from rotating during outage or motor step missing, so that a damage to the product is reduced, and the yield of the product is increased.
Description
Technical field
The present invention relates to sealed in unit to integrated circuit plastic packaging before the protective device of product, relate in particular to simple and easy automatic encapsulation device to integrated circuit plastic packaging before the protective device of product.
Background technology
In simple and easy automatic integrated antenna package field, the position of material loading part (goods release parts) is transmitted in considers that in the minimized situation of cost, the stepping motor drive screw structures that adopt are realized more, and this structure is not in the situation that cut off the power supply or the less practical function preferably of load.The band-type brake function but stepping motor does not generally cut off the power supply, if device powers down, magazine and goods are easy to drive under screw mandrel and slide to bottom under Action of Gravity Field, because tenesmus causes damage; Frequency is too high easily loses step or limited the causing of moment of torsion lost step as started due to the stepping motor self-defect in addition, in the situation that step easily appears losing in the larger stepping motor work of load, causes and shows that the position that school is good loses, fault in the time of finally can causing goods to release.In both cases, damage of product happens occasionally, and has directly affected conforming product rate.
Summary of the invention
The protective device that the purpose of this invention is to provide product before a kind of integrated circuit plastic packaging, affect the problem of conforming product rate when heavier to solve simple and easy automatic integrated antenna package equipment packages cause outage or load.
The technical solution used in the present invention is: a kind of protective device for product before integrated circuit plastic packaging, and comprise ball screw and control the motor that ball screw rotates, described ball screw is provided with brake apparatus away from an end of motor.
As a further improvement on the present invention, described brake apparatus comprises cylinder and the upper friction plate of being located at ball screw one end, and the piston rod of described cylinder is provided with lower friction plate.
As a further improvement on the present invention, the present invention also comprises controller and electromagnetically operated valve, and described controller is electrically connected to electromagnetically operated valve, and described electromagnetically operated valve is electrically connected to cylinder.
As a further improvement on the present invention, described controller is PLC.
The beneficial effect that the present invention adopts is: the present invention adopts ball screw to combine with brake apparatus in the minimized situation of cost of goods manufactured version, at outage or motor, lose when step brake apparatus and can stop the rotation of ball screw, reduce the damage of product, improved conforming product rate.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Shown in figure: 1, motor, 2, ball screw, 3, upper friction plate, 4, lower friction plate, 5, cylinder.
Embodiment
Below in conjunction with Fig. 1, the present invention is described further:
As shown in Figure 1; a kind of protective device for product before integrated circuit plastic packaging; comprise ball screw 2, control motor 1, controller and electromagnetically operated valve that ball screw rotates, ball screw 2 is provided with brake apparatus away from an end of motor 1, and brake apparatus can stop the rotation of ball screw.In the present invention, brake apparatus comprises cylinder 5 and the upper friction plate 3 of being located at ball screw one end, the piston rod of cylinder 5 is provided with lower friction plate 4, upper frictional disk 3 and lower frictional disk 4 can stop ball screw 2 to rotate when close contact, controller is electrically connected to electromagnetically operated valve, and electromagnetically operated valve is electrically connected to cylinder.Middle controller of the present invention can be PLC.
The course of work of the present invention: when needs braking ball screw, PLC sends signal, electromagnetic valve work, the piston rod of cylinder stretches out, upper frictional disk and lower frictional disk close contact stop ball screw to rotate, and realize the braking to ball screw, and electromagnetically operated valve receives the signal that PLC sends.When ball screw needed transmission work, PLC sent signal, electromagnetic valve work, and the piston rod of cylinder is regained, and upper frictional disk and lower frictional disk break away from, and ball screw is in the driven by motor operating state.In the situation that outage, PLC is output signal not, the ball screw place
In on-position.By the control of PLC to brake apparatus, the present invention has realized the protection to product before integrated circuit plastic packaging.
Above-described embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all should fall in the definite protection range of the claims in the present invention book.
