Description

Technical Field

[0001] The invention relates to the technical field of needle holders, and in particular to a burning and testing needle holder for tube-mounted ICs. Background Art

[0002] At present, data entry of tube-mounted integrated circuits (ICs) is basically done manually, which has problems such as high operation intensity, low efficiency, high failure rate, difficult cost control and high labor volume. In addition to manual operation, the data entry of tube-mounted ICs is currently carried out by a robot. The robot imitates human hand operation, takes the IC out of the tube, and places it on the IC burning equipment for data entry.

[0003] When the IC is taken out of the IC burning device and put back into the tube, the use of mechanical hand to enter IC data does reduce labor and improve efficiency. However, it takes 1 to 2 seconds to complete the data entry of one IC, and four ICs are done at the same time. It is a very big test for the entire equipment to rely on a robot to complete it in such a short time, because the robot will cause great damage to the machine when operating at high precision, high speed and high frequency. Even if it can be realized, the cost will be very expensive and ordinary users cannot use it. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a burning and testing needle holder for tube-mounted IC.

It has the characteristics of accurate fixing of the probe 54, simple installation, convenient use and easy replacement. This structure is designed according to the type of IC and has the same pitch and number of probes 54 as the IC pins. When the IC in the tube passes through the equipment quickly, the sensor gives a signal. The probe 54 of this structure can automatically, quickly and accurately contact the IC pin for burning or testing. The stable structure 8 is adopted. Turn the No. 1 screw 55, and the No. 1 screw 55 is threadedly engaged with the thread groove 81.The No. 1 screw 55 rotates and moves along the inner wall of the No. 1 hydraulic box 82, and squeezes the piston plate 83, so that the piston plate 83 squeezes the oil inside the No. 1 hydraulic box 82, and the oil inside the No. 1 hydraulic box 82 enters the No. 2 hydraulic box 84 through the leather tube 85.

[0024] The working principle of the present invention is as follows: adopting a stable structure 8, rotating the No. 1 screw 55, the No. 1 screw 55 is threadedly engaged with the thread groove 81, so that the No. 1 screw 55 rotates and moves along the inner wall of the No. 1 hydraulic box 82, and squeezes the piston plate 83, so that the piston plate 83 squeezes the engine oil inside the No. 1 hydraulic box 82, and the engine oil inside the No. 1 hydraulic box 82 enters the interior of the No. 2 hydraulic box 84 through the leather tube 85, and at the same time, the engine oil inside the No. 2 hydraulic box 84 squeezes the extrusion rod, so that the extrusion rod blocks the protrusion 87, and prevents the No. 1 screw 55 from moving, so that the connection of the No. 1 screw 55 is more stable. The structure is mainly used in the tube-mounted IC automatic burning machine. When the IC enters the burning or testing machine from the packaging feed pipe and arrives at the work station, the sensor gives a signal, and the burning test needle seat 52 installed on both sides of the IC foot is pushed by the electromagnet to contact the IC foot to perform the burning test work. After the work is completed, it automatically opens, and the IC that has completed the burning test work enters the discharge pipe, and then the burning test seat continues to work on the IC that enters the work station from the feed pipe.
