The utility model relates to the semiconductor packing molding technology field, particularly to the TO-263 packaging product detection field. A TO-263 packaging product molding detecting device comprises a material feeding part of an automatic test separator, a molding detecting block and an optical fiber sensor are arranged on a material feeding path of the material feeding part, the molding detecting block enables three pins of a packaging product to pass through a detection opening in a sliding way, the material feeding part sequentially passes through the molding detecting block and the optical fiber sensor for feeding. The TO-263 packaging product molding detecting device is simple in structure, is scientific and reasonable, is low in investment cost, is simple to operate, is very convenient to maintain and is suitable for industrial utilization and popularization, the three pins of the packaging product pass through the detecting opening of the molding detecting block in a sliding way, therefore, automatic molding detection replaces manual full inspection, the efficiency is high, the manual labor and financial resources are reduced, the human error is avoided, and the accuracy is high.

Description

TO-263 encapsulating products moulding checkout gear

Technical field:

The utility model relates to the semiconductor packages field shaping technique, especially relates to the field that the TO-263 encapsulating products detects.

Background technology:

The TO-263 transistor; Because special surface structure own, three pins of product must be pressed into the solid of definite shape size through mould, and in the process of compression moulding, unavoidably can produce the defective products that does not meet shape need; In the prior art; These substandard products are through manual work it to be chosen, and are easy to also in the time of waste of manpower, financial resources cause that human error-choose is unclean, make substandard product flow to the client on hand.

Summary of the invention:

The purpose of the utility model is to provide a kind of automatic moulding to detect the TO-263 encapsulating products moulding checkout gear that replaces artificial full inspection, and it is simple in structure, makes easily, and is easy to use.

For achieving the above object, the utility model adopts following technical scheme:

TO-263 encapsulating products moulding checkout gear includes the feeding part of automatic Test handler, is provided with moulding in the feeding path of feeding part and detects piece and Fibre Optical Sensor, and moulding detects piece to have three pins that can supply encapsulating products and slide through detecting mouthful; Feeding part feeding successively detects piece and Fibre Optical Sensor through moulding.

In the such scheme, also on the feeding part, be provided with magnetic switch, magnetic switch is controlled by a removable cover; On the feeding path of feeding part, also be provided with the push pipe cylinder, the push pipe cylinder is positioned at the preceding station place that moulding detects the feeding end of piece, the working electromagnet valve of said magnetic switch control push pipe cylinder.

In the such scheme, the detection mouth that moulding detects piece is that moulding detects the piece end and cuts open and cut formation, and moulding detects on the horizontal feeding path that is installed in the feeding part of piece, and it is horn-like detecting a mouthful input.

The utility model is simple in structure, and is scientific and reasonable, and cost of investment is low; And the operation operation is easy, and Maintenance and Repair are very convenient, accords with industrial utilization and popularization; Let three pins of encapsulating products slide the detection mouth that detects piece through moulding, can reach automatic moulding and detect the artificial full inspection of replacement, efficient is high; Reduce manpower, financial resources, avoided human error simultaneously, accuracy is high.

Description of drawings:

Accompanying drawing 1 is the preferred embodiment structural representation of the utility model;

Accompanying drawing 2 detects the structural representation of piece for moulding;

Accompanying drawing 3 is the control circuit figure of the utility model preferred embodiment.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further specified:

Consult Fig. 1,2, shown in 3; The utility model mainly is relevant a kind of TO-263 encapsulating products moulding checkout gear; Include the feeding part 1 of automatic Test handler; Be provided with moulding in the feeding path of feeding part 1 and detect piece 2 and Fibre Optical Sensor 3, moulding detection piece 2 has three pins that can supply encapsulating products and slides through detecting mouth 21; Feeding part 1 feeding successively detects piece 2 and Fibre Optical Sensor 3 through moulding.Be provided with magnetic switch 4 in feeding part 1, magnetic switch 4 is by a removable cover 5 controls; On the feeding path of feeding part 1, also be provided with push pipe cylinder 6, push pipe cylinder 6 is positioned at the preceding station place that moulding detects the feeding end of piece 2, the working electromagnet valve of said magnetic switch 4 control push pipe cylinders 6.

Shown in Figure 2, the detection mouth 21 that moulding detects piece 2 cuts open and cuts formation for moulding detects the piece end, and moulding detects on the horizontal feeding path that is installed in feeding part 1 of piece 2, and it is horn-like detecting mouth 21 inputs.

When group is established and implemented, moulding is detected on the feeding path of feeding part 1 that piece 2 is installed in automatic Test handler, in the production process, normal product can be smoothly through the detection mouth 21 of moulding detection piece 2; Block (effect that detects piece is whether testing product pin length, shape meet standard) and when bad product, will be detected piece 2 by moulding; Cause that thus Fibre Optical Sensor 3 detects less than product; Fibre Optical Sensor 3 signals upset output; Analog switch becomes normally closedly by often opening, and at this moment production equipment is shut down alarm.Open removable cover 5 subsequently; Make magnetic switch 4 signals upset output; Analog switch becomes the normally closed magnetic valve action that causes push pipe cylinder 6 by often opening; Thereby remove to drive push pipe cylinder 6 and withstand last of jammed substandard product, so just can defective products be taken out from detect piece, accomplish and once detect circulation automatically.

Concrete job step is following:

1, when Fibre Optical Sensor does not detect product, sensor output analog switch becomes closure by disconnection makes the actuating of relay.

2, when the actuating of relay, the closing of contact of relay makes the equipment downtime alarm.

3, when removing removable cover, the action of cover plate sense switch becomes closure by disconnection, thereby causes that the magnetic valve action drives the last product that cylinder withstands bad product, and substandard product just can be taken away from device like this.

4, cover removable cover again after taking bad product away, removable cover sense switch action at this moment becomes disconnection by closure; The magnetic valve outage, cylinder is return initial point under the effect of back-moving spring, and product is through detecting piece; Fibre Optical Sensor detects product; The output analog switch becomes disconnection by closure, and the relay breaker point breaks off, the equipment production that reruns.

The utility model detects with automatic moulding and replaces artificial full inspection, and efficient is high, reduces manpower, financial resources, has avoided human error simultaneously, and accuracy is high.
