[0002] Electrical contact elements are important components in high-voltage electrical equipment such as high-voltage circuit breakers, switch cabinets, disconnectors, and grounding switches. Their performance directly affects the quality and service life of these equipment. Their main function is to connect the circuit when in contact, and to open or close the circuit through their relative movement, or to keep the circuit connected by rotating or sliding. In order to improve their production efficiency, reduce production costs, and realize mechanical automation connection production, three-punch forming process is usually used to process electrical contact elements.

[0003] During the manufacturing process, electrical contact components usually need to be packaged for the convenience of subsequent management and transportation. Common packaging methods include taping, pallet packaging, tube packaging and bulk packaging. Among them, taping is not only convenient, but also can ensure the stability of electrical contact components during transportation and storage. Therefore, it is often used as a packaging method for electrical contact components.

Example

[0039] Reference Figure 1-Figure 8, a manufacturing device for an electric contact element based on a three-punch forming process, comprising a substrate 1 and a conveying device 2 and a bracket 3 installed on the substrate 1, wherein the conveying device 2 is a conventional means in the prior art, mainly comprising a conveying roller and a conveyor belt, wherein the size of the conveyor belt matches the size of the carrier belt, and further comprising: an air supply device 4 arranged on the bracket 3, the specific structure of the air supply device 4 can refer to the technical scheme in the prior art, and the technicians in this field can know it, and the exhaust and deflation of the air supply device 4 can be controlled by a solenoid valve, and an adjustment mechanism 5 is arranged on the side of the bracket 3 close to the conveying device 2, when the conveyed carrier belt overlaps or is empty, the adjustment mechanism 5 can take out the overlapping electric contact elements and replenish the empty carrier belt; a linkage mechanism 6 arranged between the conveying device 2 and the adjustment mechanism 5, for driving part of the structure on the adjustment mechanism 5 to rotate intermittently; a temporary storage component 7 arranged on the bracket 3, a monitoring probe 72 is fixedly connected to the side of the temporary storage component 7 close to the conveying device 2, the monitoring probe 72 is electrically connected to the air supply device 4, and the monitoring probe 72 can be a high-definition A clear precision camera is used to clearly monitor the placement of the electric contact elements on the carrier tape, and the monitoring probe 72 can be connected to the solenoid valve on the air supply device 4 through an electrical signal processing device. This technology is already mature in the prior art and will not be described in detail here. A dust removal mechanism 8 is arranged on the conveying device 2, which is used to adsorb dust on the carrier tape, wherein the air supply device 4 is connected to the adjustment mechanism 5, the linkage mechanism 6 and the dust removal mechanism 8, and the dust removal mechanism 8 is connected to the adjustment mechanism 5. The winding rollers at both ends of the carrier tape and the cover tape are evenly connected. During the packaging process, the electric contact elements can be placed in the holes on the carrier tape through a feeding device, such as a vibrating feeding tray and other equipment. This technology has become mature in the prior art, so it will not be described in detail here. A pressing piece 9 is also arranged on the conveying device 2. When the electric contact elements on the carrier tape are adjusted and cleaned, the cover tape can be sealed to the carrier tape through the pressing piece 9, thereby realizing the packaging of the electric contact elements. The specific structure of the pressing piece 9 can refer to the technical scheme in the prior art, and technicians in this field can know it, so it will not be described in detail here.

[0040] Reference Figure 3 and Figure 5 The adjustment mechanism 5 includes a telescopic member 51 fixedly connected to the side of the bracket 3 close to the conveying device 2, the output end of the telescopic member 51 is fixedly connected to the mounting frame 52, the mounting frame 52 is rotatably connected to a rotating drum 53, the rotating drum 53 is connected to multiple groups of adsorption heads 54, the mounting frame 52 is fixedly connected to a first air slip ring 55 connected to the rotating drum 53, and a first connecting pipe 56 is connected between the air supply device 4 and the first air slip ring 55, wherein the telescopic member 51 is connected to the air supply device 4, and the adsorption head 54 is connected to the first connecting pipe 56 through the rotating drum 53 and the first air slip ring 55.

[0041] The telescopic part 51 is extended and retracted by supplying air and sucking air through the air supply device 4, thereby adjusting the distance between the adsorption head 54 and the electric contact element to achieve adsorption of the electric contact element. It should be explained that the first air slip ring 55 is a conventional means in the prior art, and its purpose is to ensure stable delivery of gas when the drum 53 rotates.

[0042] Reference Figure 3 and Figure 4 The linkage mechanism 6 includes an extension shaft 61 connected to the conveying device 2, a first driving wheel 62 is fixedly connected to the extension shaft 61, a fixing frame 63 is fixedly connected to the side of the mounting frame 52 close to the extension shaft 61, a connecting shaft 611 is rotatably connected to the side of the mounting frame 52 close to the fixing frame 63, a mounting shaft 68 matching the connecting shaft 611 is rotatably connected to the fixing frame 63, a second air slip ring 612 rotatably connected to the mounting shaft 68 is fixedly connected to the fixing frame 63, a first driven wheel 69 is fixedly connected to the end of the mounting shaft 68, a second connecting pipe 619 is connected between the second air slip ring 612 and the air supply device 4, a limiting disk 613 is fixedly connected to the connecting shaft 611, a driving rod 614 is fixedly connected to the limiting disk 613, and a groove 6 is provided on the side of the limiting disk 613 close to the driving rod 614. 15. An adjusting disk 616 connected to the rotating drum 53 is rotatably connected to the mounting frame 52. The adjusting disk 616 is provided with a plurality of positioning grooves 617 matching the driving rod 614. The adjusting disk 616 is provided with a plurality of limiting grooves 618 matching the limiting disk 613. A tensioning assembly is provided on the side of the bracket 3 close to the first driving wheel 62. A first belt 610 is sleeved between the first driving wheel 62, the tensioning assembly and the first driven wheel 69. A control assembly is provided between the second air slip ring 612 and the mounting shaft 68. The tensioning assembly includes a slide groove 64 provided on the bracket 3. A slider 65 is slidably connected in the slide groove 64. A first spring 66 is fixedly connected between the slider 65 and the slide groove 64. A tensioning wheel 67 is rotatably connected to the slider 65. The tensioning wheel 67 and the first belt 610 fit tightly.

[0043] The number of adsorption heads 54 and positioning grooves 617 is the same, preferably four groups. When the limit plate 613 rotates, it drives the driving rod 614 to rotate. Under the action of the positioning groove 617, it will drive the adjusting plate 616 and the rotating drum 53 to rotate. After the driving rod 614 is disengaged from the positioning groove 617, the adjusting plate 616 stops rotating. During this process, the limit plate 613 matches the limit groove 618 on the adjusting plate 616. It should be explained that the resistance between the rotating drum 53 and the mounting frame 52 is large. In the absence of a large external force, the rotating drum 53 will not rotate a large angle even under the action of inertia, that is, it will not affect the position of the adsorption head 54 during rotation. During this process, under the action of the first spring 66, when the height of the rotating drum 53 changes, the first belt 610 is always in close contact with the first driven wheel 69, thereby ensuring the stable rotation of the rotating drum 53.

[0044] Reference Figure 4 and Figure 7 The control component includes an annular groove 6121 provided in the second air slip ring 612, a plurality of connecting channels 6122 communicating with the annular groove 6121 are provided on the mounting shaft 68, a mounting groove 6123 communicating with the connecting channel 6122 is provided on the side of the mounting shaft 68 close to the connecting shaft 611, a second spring 6124 is fixedly connected to the side of the connecting channel 6122 close to the mounting groove 6123, a locating pin 6125 slidably connected to the mounting groove 6123 is fixedly connected to the end of the second spring 6124, a slot 6126 matching the locating pin 6125 is provided at the end of the connecting shaft 611, wherein the annular groove 6121 is communicated with the second connecting pipe 619, and the end of the connecting shaft 611 is rotatably connected to the mounting shaft 68.

[0045] When the monitoring probe 72 detects that the electrical contact elements are overlapping or empty, the gas in the gas supply device 4 is transported to the second air slip ring 612 through the second connecting pipe 619, driving the positioning pin 6125 to move to the slot 6126, thereby driving the rotating drum 53 to rotate. It should be explained that even if the positioning pin 6125 and the slot 6126 are in an offset state at the beginning, as the positioning pin 6125 rotates, until the positioning pin 6125 rotates to match the slot 6126, the positioning pin 6125 moves into the slot 6126. When the electrical contact elements are overlapping, the overlapping electrical contact elements are adsorbed by the adsorption head 54 until the electrical contact elements are transported to the temporary storage box 71. When the carrier tape has an empty package, the adsorption head 54 adsorbs the electrical contact elements in the temporary storage box 71, and transports the electrical contact elements to the empty package of the carrier tape and places them.

[0046] Reference Figure 3 and Figure 6The temporary storage component 7 includes a temporary storage box 71 fixedly connected to the side of the bracket 3 close to the adsorption head 54, a sealed cavity 73 is opened at the bottom of the temporary storage box 71, a baffle 74 is slidably connected inside the sealed cavity 73, a third spring 75 is fixedly connected between the baffle 74 and the sealed cavity 73, a plurality of linkage cylinders 76 are fixedly connected to the side of the temporary storage box 71 away from the adsorption head 54, the end of the linkage cylinder 76 is fixedly connected to a push plate 78 slidably connected to the temporary storage box 71, a fourth spring 77 is fixedly connected between the push plate 78 and the temporary storage box 71, wherein the bottom of the temporary storage box 71 is open on one side close to the adsorption head 54, and the linkage cylinder 76 is connected to the air supply device 4 through a pipeline.

[0047] When the equipment is operating normally (there is no overlap or empty pack of the electric contact elements on the carrier), the baffle 74 fits tightly against the inner wall of the temporary storage box 71, and the electric contact elements stay in the temporary storage box 71. When the overlapping electric contact elements are transported to the temporary storage box 71, the electric contact elements on the adsorption head 54 will stay in the temporary storage box 71 under the action of the side wall of the temporary storage box 71. When an empty pack appears on the carrier, the gas supply device 4 transports gas to the linkage cylinder 76, driving the push plate 78 to move the electric contact elements to the opening of the temporary storage box 71. At the same time, the gas supply device 4 adsorbs the gas in the sealed cavity 73, driving the baffle 74 to be stored in the sealed cavity 73. At this time, the electric contact elements fall through the opening and are adsorbed by the adsorption head 54. Then, the electric contact elements are transported to the empty pack of the carrier. It should be explained that the size of the opening of the temporary storage box 71 matches the size of a single electric contact element.

[0048] Reference Figure 5 , and also includes a telescopic connecting member 57 fixedly connected to the side of the mounting frame 52 close to the rotating drum 53, and the end of the telescopic connecting member 57 is fixedly connected to a cleaning disk 58, the telescopic connecting member 57 is elastic, and the size of the cleaning disk 58 is larger than the size of the adsorption head 54.

[0049] During the rotation of the drum 53, the cleaning disc 58 can clean the dust adsorbed on the adsorption head 54 to prevent the dust from clogging the adsorption head 54 and affecting the adsorption of the electrical contact elements. It should be explained that the contact between the cleaning disc 58 and the adsorption head 54 will not cause the electrical contact elements adsorbed on the adsorption head 54 to fall off.

[0050] Reference Figure 2 and Figure 8The dust removal mechanism 8 is fixedly connected to the mounting platform 81 on the conveying device 2, and a dust box 82 is fixedly connected to the side of the mounting platform 81 close to the conveying device 2. A third connecting pipe 83 is connected between the dust box 82 and the air supply device 4. A filter plate 84 is fixedly connected to the inside of the dust box 82, and a dust box 85 slidably connected to the mounting platform 81 is inserted on the side wall of the dust box 82, wherein the filter plate 84 is inclined, and the top of the dust box 85 is close to the bottom of the filter plate 84, the dust box 85 is connected to the dust box 82, and the inner wall of the dust box 82 close to the dust box 85 is inclined and fixedly connected with a guide plate 86.

[0051] During the transportation of the carrier tape, the air supply device 4 absorbs the air in the dust box 82 through the third connecting pipe 83, so that a negative pressure is generated on the side of the dust box 82 close to the carrier tape, thereby sucking the dust on the carrier tape into the dust box 82 and intercepting the dust through the filter plate 84. It should be explained that the suction force generated by the dust box 82 on the carrier tape cannot cause the electrical contact elements to be adsorbed on the dust box 82.

[0052] Reference Figure 4 and Figure 8 , and also includes a reciprocating screw 87 rotatably connected to the dust box 82, and a slide 811 slidably connected to the bottom of the dust box 82 is provided on the reciprocating screw 87, and an elastic retractable scraper 812 is fixedly connected to the side of the slide 811 close to the filter plate 84, and the inner wall of the dust box 82 is symmetrically fixedly connected with a compression cylinder 813, wherein the end of the reciprocating screw 87 away from the dust box 85 extends to the outside of the mounting platform 81, and the end of the reciprocating screw 87 is fixedly connected to the second driven wheel 88, and the second driving wheel 89 is fixedly connected to the extension shaft 61, and a second belt 810 is sleeved between the second driving wheel 89 and the second driven wheel 88, and the compression cylinder 813 is connected to the telescopic connecting member 57 through a pipeline.

[0053] During the conveying process of the carrier belt, the reciprocating screw 87 is driven to rotate through the second driving wheel 89, the second driven wheel 88 and the second belt 810, driving the elastic retractable scraper 812 to move back and forth along the filter plate 84 and scrape off the dust adsorbed on the filter plate 84. When the elastic retractable scraper 812 moves toward the side of the dust collecting box 85, part of the dust can be collected in the dust collecting box 85 through the guide plate 86. When the elastic retractable scraper 812 moves in the opposite direction, the dust adsorbed on the filter plate 84 can fall off and then be re-adsorbed on the filter plate 84. As the elastic retractable scraper 812 moves, part of the fallen dust will move to The other side of the elastic retractable scraper 812 is moved until the dust is collected in the dust box 85, wherein the elastic retractable scraper 812 can be realized by arranging an elastic part inside, which is a conventional method in the prior art and is not elaborated here. When the elastic retractable scraper 812 moves to the side wall of the dust box 82, it will squeeze the compression cylinder 813 and transport the gas to the telescopic connecting piece 57. The compression cylinder 813 is elastic. Through the reciprocating movement of the elastic retractable scraper 812, the cleaning disc 58 can be driven to vibrate to clean the dust on the adsorption head 54, thereby improving the cleaning effect of the adsorption head 54.
