[0002] Measuring machine refers to the device for detecting and packaging electronic components by its mechanism, and the measuring machine is a device for determining whether electronic components can be used by detecting them in the production process. The existing single material feeding device of measuring machine is usually provided with a separating part, which is used to adsorb one of a plurality of materials arranged in sequence to a specified position to separate the material from the column of materials. The separating material basically uses electromagnet and separating needle. By moving the separating needle upwards, two adjacent materials are separated, and then one material is sucked away by the feeding vacuum pipeline. The separating needle moves downwards, and the next material can move to the position that can be adsorbed by the feeding vacuum pipeline. The separating needle continues to move upwards to separate the two materials. In this way, the electromagnet generates suction force to pull down the separating needle, so that the top of the separating needle is below the bottom surface of the material. The material can pass through the passage. After the material passes, the electromagnet releases the suction force, and the spring pushes the electromagnet to automatically move upwards to block the movement passage of the material. The feeding vacuum pipeline sucks away one material, and the cycle continues. In this way, the following disadvantages exist:

DETAILED DESCRIPTION

[0027] The utility model will be further described in connection with the drawings and embodiments:

[0028] Embodiment one: see Figures 1 to 5 The separating device of the measuring package machine, including inlet base 1, separating needle 2 and separating needle drive part, the separating needle drive part is set in the lower of the inlet base 1, the top of the separating needle 2 is inserted in the inlet base 1, the separating needle drive part drives the separating needle 2 to move up and down,

[0029] The separating needle drive part includes support 3, piezoelectric brake 4 and limit spring 5, the top of the support 3 is connected with the inlet base 1, the piezoelectric brake 4 is installed on the support 3, the piezoelectric brake 4 is equipped with execution part 6, the piezoelectric brake 4 drives the execution part 6 to swing relative to the piezoelectric brake 4;

[0030] The lower of the separating needle 2 is connected with the execution part 6, the limit spring 5 is set in the upper of the execution part 6, one end of the limit spring 5 is fixedly connected with the support 3, and the other end is connected with the separating needle 2.

[0031] In this embodiment, taking the illustrated direction as an example, see... Figure 3 As shown, the feeding base 1 has a first hole 7, with both ends of the first hole connected to the top and bottom surfaces of the base. The top of the separating needle is inserted into the first hole. A feeding port 8 is located at the right end of the first hole, positioned to the right of the first hole. A vacuum adsorption hole 9, connected to the feeding port, is located on the bottom right side of the base and is used to connect to a vacuum adsorption tube. Two baffles (not shown in the figure) are also installed on the top of the base, spaced apart, forming a material channel between them. The first hole and feeding port are located within this material channel. A cover plate is also installed, positioned above the material channel and above the feeding port, and above the first hole to the right, without obstructing it. When the separating needle moves upward, its top passes through the first hole and is positioned above it, entering the material channel. When the separating needle moves downward, its top retracts into the first hole. In actual operation, materials are introduced into the material channel from left to right. The distance between the first aperture and the inlet is the size of one product, or slightly larger. After the product passes through the first aperture, the piezoelectric actuator drives the actuator of the piezoelectric vibrator to swing upwards, pushing the separating needle upwards so that it passes through the first aperture and is positioned above it, separating the two products. The negative pressure of the vacuum suction hole sucks away the material on the right side of the separating needle. Then, the piezoelectric actuator controls the actuator of the piezoelectric vibrator to swing downwards, causing the separating needle to move downwards and retract into the first aperture. The material on the left can move to the right end of the first aperture, and then the separating needle continues to move upwards, thus repeating the cycle. This method achieves material separation and feeding.

[0032] In this embodiment, the right end of the piezoelectric actuator is the actuator. The piezoelectric actuator is a piezoelectric ceramic bicrystalline wafer, with the right end serving as the actuator. The left end of the piezoelectric ceramic bicrystalline wafer is connected to a support. When the piezoelectric ceramic bicrystalline wafer is energized, it drives the actuator to oscillate relative to the piezoelectric ceramic bicrystalline wafer (e.g., ...). Figure 4 As shown, the middle part of the separating needle is connected to the actuator, and the left end of the limiting spring is connected to the bracket. When the actuator swings, it drives the separating needle to move up and down and swing. The limiting spring prevents the separating needle from swinging forward and backward during its up-and-down movement and swinging, ensuring that the separating needle can only move up and down and swing left and right (with a very small swing amplitude). Since the vertical movement distance of the separating needle does not exceed 300µm, and the single swing displacement time is between 0.4ms and 3ms, although the actuator is swing-type, its movement is basically vertical with a very small swing amplitude. In this method, the rapid vertical movement speed of the separating needle increases the material separation efficiency.

[0033] Moreover, in the embodiment, a piezoelectric brake is used to drive the swing of the execution part, the swing amplitude of the execution part can be adjusted by adjusting the voltage of the piezoelectric brake, that is, the up-down moving distance of the separating needle can be adjusted, in this way, the moving distance of the separating needle can be accurately controlled, the piezoelectric brake is connected with the controller of the bale tester, the voltage of the piezoelectric brake is controlled by the controller to control the up-down moving distance of the separating needle in real time, and the moving distance of the separating needle can be displayed on the bale tester or remotely displayed and controlled through the Internet of Things.

The first mounting plate and the second mounting plate are used to connect and mount the separating needle, the execution part and the limiting elastic sheet, and are convenient for subsequent disassembly, maintenance and replacement.

[0037] The limiting plate is arranged to limit the up-down movement of the separating needle, prevent the separating needle from moving downward and upward excessively, and when the separating needle moves downward and exceeds the range, the bottom surface of the second mounting plate will abut against the limiting plate to limit the second mounting plate and the separating needle from continuing to move downward, thereby playing a mechanical limiting role. Similarly, if the separating needle moves upward excessively, the top surface of the first mounting plate will abut against the limiting plate to limit the separating needle from moving upward excessively, thereby playing a mechanical limiting role.

Remote monitoring and control can be realized through the Internet of Things and the Internet, and intelligent and digital control can be realized.
