Description

Technical Field

[0001] The present invention relates to an apparatus for assembling a rubber sleeve on a resistive chip, and more particularly to an automatic assembling apparatus for an aluminum spraying die sleeve of a zinc oxide resistive chip. Background Art

[0002] The zinc oxide lightning arrester is a new type of lightning arrester developed in the 1970s. It is mainly composed of zinc oxide resistive chips and is an electrical product used to protect various electrical equipment in the power system from overvoltage damage, with good protection performance. Because the non-linear volt-ampere characteristic of the zinc oxide resistive chip is very excellent, only a few hundred microamperes of current passes through under normal working voltage, which is convenient for designing a gapless structure, making it have the characteristics of good protection performance, light weight, and small size. When an overvoltage invades, the current flowing through the resistive chip increases rapidly, while limiting the amplitude of the overvoltage and releasing the energy of the overvoltage. After that, the zinc oxide resistive chip returns to the high-resistance state, enabling the power system to work normally.

[0003] In the aluminum spraying step of the production preparation process of the zinc oxide resistive chip, when spraying aluminum on the upper and lower surfaces of the resistive chip, it is necessary to ensure that the side surfaces of the resistive chip are not touched by aluminum powder. At present, manual labor is used to insert the resistive chip into a customized male rubber sleeve and female rubber sleeve to protect its side surfaces. Workers need to manually place the male sleeve in the center of the mold, then accurately place the resistive chip above the male sleeve, manually pull the lever to make the cylinder press the resistive chip into the male sleeve, and then accurately place the female sleeve above the resistive chip, and repeat the lever pulling operation to press the female sleeve onto the resistive chip to complete the sleeve pressing work. Since the rubber sleeve and the resistive chip need to be closely fitted, the gap between the rubber sleeve and the resistive chip is small, and even skilled workers cannot accurately press the rubber sleeve onto the resistive chip every time. Moreover, the manual sleeve pressing method has a high working intensity, and it is inevitable to touch the surface of the resistive chip by hand, which affects the yield rate of the resistive chip, and has low efficiency, resulting in a waste of human resources. The working environment in the resistive chip production workshop is harsh, and with the emergence of the shortage of labor, fewer and fewer young people choose to engage in such simple mechanical work, and the factory gradually shows problems such as an aging workforce and increasing labor costs. Summary of the Invention

[0027] The working process of the automatic pressing device designed by the present invention is described as follows: First, press the start button of the equipment, the motor 44 of the equipment is turned on, the first three-axis cylinder 27 pushes the clamping claw piece to move downward, and after it is in place, the opening clamping cylinder 25 contracts to drive the clamping claw to clamp the male sleeve, and the first three-axis cylinder 27 contracts to drive the male sleeve to rise and leave the loading area. The male sleeve clamping claw mechanism 10 moves to the male sleeve placing station 6 through the linear guide 57, and the first three-axis cylinder 27 moves downward to put the male sleeve into the mold installed on the circular workbench 2. The male sleeve clamping claw mechanism 10 returns to the initial position and waits. After completing the male sleeve placing action, give the motor 44 a start instruction to make the cam divider 4 drive the circular workbench 2 to rotate 90° counterclockwise and then stop.

After completion, the clamp mechanism 12 is placed to press-fit the female sleeve onto the resistor of the mold, and the clamp mechanism 12 is placed to return to the initial position for standby. After the female sleeve press-fitting action is completed, a start command is given to the motor 44, so that the cam divider 4 drives the circular worktable 2 to rotate 90° counterclockwise and then stop rotating.
