When the first clamping unit 443 contacts the button 20 on the button picking position 4211, control the first clamping unit 443 to clamp the button 20;

[0115] Control the thirteenth lifting unit 4412 to drive the rotating unit 442 to rise. The rise of the rotating unit 442 will drive the first clamping unit 443 clamping the button 20 to rise;

[0116] Control the fifth slide 4411 to drive the thirteenth lifting unit 4412 to move above the button assembly position to convey the first clamping unit 443 clamping the button 20 above the button assembly position;

[0117] The thirteenth lifting unit 4412 is controlled to drive the rotating unit 442 to descend. The descent of the rotating unit 442 drives the first clamping unit 443 to descend, so that the first clamping unit 443 drives the button 20 to approach and install it to the button assembly position;

[0118] After the button 20 is assembled in place, the first clamping unit 443 is controlled to release the button 20, and then the thirteenth lifting unit 4412 is controlled to drive the rotating unit 442 and the first clamping unit 443 to rise to the initial position;

The first lifting unit 423 is used to drive the second clamping unit 422 to rise and fall, and the second clamping unit 422 can drive the head of the button 20 to leave the button material taking position 4211 after rising.

[0126] The steps of using the button output module 420 to output the button 20 are as follows:

[0127] Control the button loading module 410 to output the button 20 to the button taking position 4211;

[0128] Control the first lifting unit 423 to drive the second clamping unit 422 to rise. When the second clamping unit 422 contacts the button 20, control the second clamping unit 422 to clamp the tail of the button 20.

[0129] Control the first lifting unit 423 to drive the second clamping unit 422 clamping the button 20 to continue rising for a preset stroke, so that the head of the button 20 is separated from the button picking position 4211. The button 20 with its head separated from the button picking position 4211 is convenient for the first clamping unit 443 to clamp. When the first clamping unit 443 clamps the head of the button 20, control the second clamping unit 422 to release the button 20.

[0130] After the button 20 is taken away, control the first lifting unit 423 to drive the second clamping unit 422 to descend to the initial position.

Among them, an installation arm 311 is provided on the second bracket 310, and one end of the installation arm 311 extends above the spring assembly position. The spring feeding module 320 includes a spring feeding unit 321 and a spring conveying pipe 322 communicating with the discharge port of the spring feeding unit 321. The outlet end of the spring conveying pipe 322 is installed on the installation arm 311 and is directly opposite to the spring assembly position. For the convenience of understanding, the spring located at the lowermost part of the outlet end of the spring conveying pipe 322 is defined as the first spring, and the spring adjacent to the first spring is defined as the second spring. A notch 3221 is provided on the outer peripheral wall of the outlet end of the spring conveying pipe 322, and the notch 3221 is opposite to the first spring and the second spring. The spring misalignment module 330 includes a first telescopic unit 331, a second telescopic unit 332, a first dividing needle 333, and a second dividing needle 334. The first telescopic unit 331 and the second telescopic unit 332 are both arranged on the third bracket 521. The output end of the first telescopic unit 331 is connected to the first dividing needle 333, and the first telescopic unit 331 is used to drive the first dividing needle 333 to expand and contract. After the first dividing needle 333 extends out, it can pass through the notch 3221 and extend into the first spring to limit the fall of the first spring. The output end of the second telescopic unit 332 is connected to the second dividing needle 334, and the second telescopic unit 332 is used to drive the second dividing needle 334 to expand and contract. After the second dividing needle 334 extends out, it can pass through the notch 3221 and extend into the second spring to limit the fall of the second spring.

[0135] Specifically, the steps of assembling the spring using the spring assembly mechanism 300 are as follows:

[0136] Control the spring feeding unit 321 to convey the springs into the spring conveying pipe 322 one by one. When the first spring is conveyed to the outlet end of the spring conveying pipe 322, control the first telescopic unit 331 to drive the first dividing needle 333 to extend out, intercept the first spring, and make the subsequent second spring and the like be arranged in sequence behind the first spring in turn, completing the preparatory work for spring feeding;

[0137] Place the upper cover 10 of the spring to be assembled under the spring conveying pipe 322, and make the outlet end of the spring conveying pipe 322 directly opposite to the spring assembly position on the upper cover 10;

[0138] Control the first telescopic unit 331 to control the first dividing needle 333 to retract, and at the same time control the second telescopic unit 332 to control the second dividing needle 334 to extend out. At this time, the first spring freely falls from the outlet end of the spring conveying pipe 322 to the spring assembly position, completing the assembly of the spring. At the same time, the second spring will be limited by the second dividing needle 334 and will not fall;

[0139] Control the second telescopic unit 332 to drive the second material separating needle 334 to retract and release the second spring, so that the second spring falls freely to the position of the first spring. When the second spring falls to the position of the first spring, control the first telescopic unit 331 to drive the first material separating needle 333 to extend. That is, the first material separating needle 333 and the second material separating needle 334 are staggered and telescopic to realize the assembly of the springs for each upper cover 10.

[0140] The spring assembly mechanism 300 has a simple structure, can realize the assembly of springs one by one, and the springs are automatically assembled after falling by the gravity of the springs, which simplifies the structure of the components.

And, a right plastic box picking position 5141 is provided at one end of the receiving table close to the left plastic box picking position 5121. A pushing unit 515 is provided on the right plastic box picking member, and the pushing unit 515 is used to push the right plastic box to the right plastic box picking position 5141. With such a setting, the left plastic box picking position 5121 and the right plastic box picking position 5141 can be made as close as possible, which is convenient for the plastic box pre-assembly module 520 to carry the left plastic box and the right plastic box simultaneously.

Through the nameplate discharging hole 1022 on the limit plate 1021, the loading of the nameplate 32 into the nameplate assembly position can be guided to avoid the nameplate 32 being placed obliquely. It can be understood that the nameplate discharging hole 1022 should be designed to be shaped like the nameplate 32 to ensure the guiding effect.

[0239] The fourth sliding table 1040 is arranged on the tenth bracket 1030.

[0240] The ninth lifting unit 1050 is arranged on the fourth sliding table 1040.

A nameplate suction head 1051 is provided at the output end of the ninth lifting unit 1050. The nameplate suction head 1051 is used to suck the nameplate 32 at the nameplate material taking position and place the nameplate 32 at the nameplate discharging hole 1022. The picking and placing of the nameplate 32 are realized by adsorption, which is beneficial to protecting the nameplate 32.

[0241] The tenth lifting unit 1060 is arranged on the fourth sliding table 1040 and moves synchronously with the ninth lifting unit 1050. When the ninth lifting unit 1050 is at the sign picking position, the tenth lifting unit 1060 is at the sign discharging hole 1022. A pressing head 1061 is provided at the output end of the tenth lifting unit 1060. The tenth lifting unit 1060 is used to drive the pressing head 1061 to lift and lower. After the pressing head 1061 descends, it can press the sign 32 in the sign discharging hole 1022 against the face cover 31. That is, when the pressing head 1061 is in the working condition of pressing the sign 32, the sign suction head 1051 is in the working condition of sucking the sign 32. With such a setting, the assembly efficiency of the sign 32 is improved. The fourth sliding table 1040 can drive the ninth lifting unit 1050 and the tenth lifting unit 1060 to move synchronously, which is beneficial to reducing the use of components.

[0242] Optionally, during the process of pressing and assembling the sign 32 onto the upper cover 10 by the pressing head 1061, in order to improve the uniform stress of the sign 32, the pressing head 1061 can be designed to be shaped like the sign 32, so that the shape of the pressing head 1061 is the same as that of the sign 32.

[0243] Furthermore, continue to refer to Figure 1 This plastic case circuit breaker upper cover assembly device further includes an upper cover conveyor line 200, and the upper cover conveyor line 200 is used to convey the upper cover 10 to achieve the automatic assembly of the upper cover 10.

[0244] Moreover, along the conveying direction of the upper cover 10, a spring assembly station, a button assembly station, a plastic box assembly station, and a face cover assembly station are successively arranged on the upper cover conveyor line 200. Positioning lifting mechanisms 210 are provided at the spring assembly station, the button assembly station, the plastic box assembly station, and the face cover assembly station. The positioning lifting mechanisms 210 are used to fix the upper cover 10 and lift the upper cover 10 to be separated from the upper cover conveyor line 200. With such a setting, at the spring assembly station, the button assembly station, the plastic box assembly station, and the face cover assembly station, the upper cover 10 can be separated from the upper cover conveyor line 200 to perform the assembly of relevant components.

[0245] Specifically, when the upper cover conveyor line 200 conveys the upper cover 10 to the spring assembly station, the positioning lifting mechanism 210 arranged at the spring assembly station will fix the upper cover 10 and lift it to be separated from the upper cover conveyor line 200. Then, the spring assembly mechanism 300 assembles the spring onto the upper cover 10.

[0246] After the spring is assembled, the positioning and lifting mechanism 210 will lower the upper cover 10 onto the upper cover conveying line 200, and the upper cover conveying line 200 will continue to convey the upper cover 10 to the button assembly station.

[0253] The lifting module 212 includes an eleventh lifting unit 2121 and a bottom support 2122. The eleventh lifting unit 2121 is arranged on the base 2111, and the output end of the eleventh lifting unit 2121 is connected to the bottom support 2122. The eleventh lifting unit 2121 is used to drive the bottom support 2122 to lift. After the bottom support 2122 rises, it can drive the upper cover 10 thereon to disengage from the upper cover conveying line 200 and abut against the limiting part 2113.

[0254] The positioning module 213 includes a twelfth lifting unit 2131 and a baffle 2132. The twelfth lifting unit 2131 is arranged on the base 2111 and is located downstream of the lifting module 212. The output end of the twelfth lifting unit 2131 is connected to the baffle 2132 and is used to drive the baffle 2132 to lift. After the baffle 2132 rises, it can abut against the side of the upper cover 10 conveyed onto the bottom support 2122 to position the upper cover 10 on the bottom support 2122.

[0255] Taking the upper cover conveying line 200 conveying the upper cover 10 to the spring assembly station as an example, the working principle of this positioning and lifting mechanism 210 is briefly introduced as follows:

Then, the eleventh lifting unit 2121 will drive the bottom support 2122 to drive the upper cover 10 to rise until the upper cover 10 abuts against the limiting part 2113. After that, the spring assembly mechanism 300 assembles the spring. When the spring is assembled, the eleventh lifting unit 2121 will drive the bottom support 2122 to drive the upper cover 10 to descend until the upper cover 10 is placed on the upper cover conveying line 200. Then, the twelfth lifting unit 2131 will drive the baffle 2132 to descend to cancel the limitation of the baffle 2132 on the upper cover 10. At this time, the upper cover 10 can move to the button assembly station under the conveyance of the upper cover conveying line 200.

[0257] Through the cooperation of the baffle 2132 and the bottom support 2122, this positioning and lifting mechanism 210 can realize reliable fixation of the upper cover 10 to ensure the reliability of lifting the upper cover 10. Through the cooperation of the bottom support 2122 and the limiting part 2113, the upper cover 10 can also be reliably fixed to ensure that the position of the upper cover 10 is fixed during the assembly of components, improving the accuracy of component assembly.
