[0021] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 2 As shown, an automatic nut terminal block assembly device for solid-state relay assembly includes a frame A1. Frame A1 is equipped with a feed conveyor belt A2, a feed handling assembly A3, a material channel A4, a nut installation assembly A5, a nut detection assembly A6, a terminal block installation assembly A7, a terminal block detection assembly A8, a discharge handling assembly A9, a discharge conveyor belt A10, and a defective product conveyor belt A12. The end of the material channel A4 is connected to the discharge conveyor belt A10. The material channel A4 is equipped with a shift fork transmission assembly. The nut installation assembly A5, the nut detection assembly A6, the terminal block installation assembly A7, and the terminal block detection assembly A8 are sequentially arranged to the side of the material channel A4 along the material conveying direction. The feed handling assembly transports the solid-state relay housing from the feed conveyor belt to the material channel. The discharge handling assembly A9 and the defective product conveyor belt A12 are arranged to the side of the discharge conveyor belt A10. The nut detection assembly A6 and the terminal block detection assembly A8 are both probes and probe-type detection components, which are prior art and will not be described in detail herein.

[0023] The working process of this device is as follows:

[0024] The solid-state relay housing is placed on infeed conveyor A2 and transported to the end. Infeed handling assembly A3 transports the solid-state relay housing at the end of infeed conveyor A2 to material channel A4. The housing is then transported by the shift fork conveyor assembly through nut installation assembly A5, nut inspection assembly A6, terminal block installation assembly A7, and terminal block inspection assembly A8 for nut installation and inspection. After the terminal block is installed and inspected, if all tests pass, the assembled housing is transported along material channel A4 and finally to outfeed conveyor A10. If the test fails, outfeed handling assembly A9 transports the rejected product to rejected product conveyor A12. After completing the corresponding processes, no manual product transfer is required. A single machine can complete the assembly of solid-state relay nuts and terminal blocks, inspect the finished product, and distinguish between qualified and rejected products. This highly automated and efficient process meets the requirements of fully automated production.

[0025] In this embodiment, the feed conveying assembly A3 and the discharge conveying assembly A9 have the same structure. Taking the feed conveying assembly A3 as an example, Figure 3 As shown, the material feeding and handling assembly A3 includes a material picking claw A21, a first driving cylinder A22 for driving the material picking claw A21 to clamp or release, a first fixed plate A23 is provided on the side of the material picking claw A21, and a slider guide cylinder assembly A24 is provided on the first fixed plate A23 for driving the first fixed plate A23 to move horizontally and vertically.

[0026] In this embodiment, the nut installation assembly A5 includes a nut feeding mechanism and a nut installation mechanism. The nut feeding mechanism includes a first vibration plate and a nut material channel connected to the first vibration plate. The nut vibration feeding is a prior art and will not be described in detail herein. Figure 4As shown, the nut mounting mechanism includes an adapter seat A31, which is arranged at the end of the nut material channel. The adapter seat A31 is provided with a biasing block A32 which can move relative to the adapter seat A31, and the biasing block A32 is provided with two nut grooves A33. The driving cylinder A35 drives the biasing block A32 to move so that the nuts transmitted through the nut material channel fall into the two nut grooves A33 respectively. Two nut suction nozzles A34 and two stripping ejector rods A36 are provided above the nut groove A33. The lower end of the nut suction nozzle A34 is provided with a groove for accommodating a single nut, and the upper end of the groove is provided with an annular strong magnet. The stripping ejector rod A36 is passed through the middle of the annular strong magnet. The nut suction nozzle A34 absorbs the nut through the annular strong magnet, and the groove ensures that only a single nut is absorbed each time. Furthermore, a nut ejector rod A25 is provided below the nut groove A33. The nut ejector rod A25 pushes the nut in the nut groove A33 into the groove, making the nut absorption more stable. A second fixed plate A38 is provided on the side of the nut suction nozzle A34, and a slider guide cylinder assembly A39 is provided on the second fixed plate A38 for driving the second fixed plate A38 to move horizontally and vertically. After the nut suction nozzle A34 sucks the nut in the nut groove A33, it is driven by the slider guide cylinder assembly A39 to move to the material channel A4, and the stripping ejector rod A36 pushes the nut in the groove downward to the terminal nut installation position of the shell.

[0027] The terminal board installation assembly includes a terminal board feeding mechanism and a terminal board pressing mechanism. Since a total of 4 terminal boards need to be installed, and the positive and negative terminal boards have different styles, in order to improve production efficiency, two sets of terminal board feeding mechanisms are used in this embodiment, such as Figure 1 and Figure 5 As shown, the terminal board feeding mechanism includes a second vibrating disk, a terminal board material channel connected to the second vibrating disk, a terminal board claw assembly is provided at the end of the terminal board material channel, the terminal board claw assembly includes a terminal board claw A41, a pressure rod seat A43, the pressure rod seat A43 is provided on the outside of the terminal board claw A41 and the lower end extends to the middle of the terminal board claw A41, a pressure rod A42 is provided at the lower end of the pressure rod seat A43, and a spring is provided between the pressure rod A42 and the pressure rod seat A43. Since the terminal board is a thin workpiece, the setting of the pressure rod A42 ensures that it will not loosen during the grasping process. A third fixed plate is provided on the side of the terminal block claw assembly, and a slider guide cylinder assembly is provided on the third fixed plate for driving the third fixed plate to move horizontally and vertically; the terminal block pressing mechanism includes a movable plate A47 and a pressing plate A46, and the movable plate A47 is connected to the pressing plate A46 by a number of pressing guide pillars A49, and the pressing guide pillars A49 are provided with buffer springs. The upper end of the movable plate A47 is provided with a second driving cylinder A40 for driving the movable plate A47 to move up and down. The buffered pressing plate ensures that the thin terminal block will not be crushed, thereby improving the product yield.

[0028] like Figure 6As shown, the shift fork conveyor assembly includes a sliding plate A53, equipped with several equally spaced shifter fingers A52. These fingers A52 are adapted to the length of the housing and provide initial positioning and conveying functions. A fourth fixed plate A54 is located to the side of sliding plate A53, and a slider guide cylinder assembly is mounted on this fourth fixed plate A54 to drive the fourth fixed plate's horizontal and vertical movement. A guide block A51 is located to the side of the material channel. A third drive cylinder is installed at its lower end to drive the guide block's vertical movement. This guide block A51 provides secondary positioning, ensuring accurate positioning during nut and terminal block installation.

[0029] The embodiments should not be regarded as limiting the present invention, and any non-inventive improvements based on the spirit of the present invention should be regarded as falling within the protection scope of the present invention.
