DETAILED DESCRIPTION

[0029] The application will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related content, and are not a limitation on the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.

[0030] It should be noted that the embodiments and features in the embodiments can be combined with each other without conflict. The application will be described in detail below with reference to the drawings and embodiments.

[0031] As Figures 1 to 3As shown, the silver plating device for the end face of the vacuum interrupter provided by the present application comprises a frame 1, a product feeding positioning mechanism 2, a brushing oscillating mechanism 3, a blowing mechanism 5, a product discharging positioning mechanism 6 and a clamping tool 4 installed on the frame 1; the clamping tool 4 is used for clamping the vacuum interrupter and transferring the clamped vacuum interrupter between the product feeding positioning mechanism 2, the brushing oscillating mechanism 3, the blowing mechanism 5, the product discharging positioning mechanism 6 and the clamping tool 4, and turning over the clamped vacuum interrupter; the product feeding positioning mechanism 2 is used for placing the vacuum interrupter before brushing, so that the vacuum interrupter to be brushed is placed in a fixed position, thereby facilitating the clamping of the clamping tool 4; the brushing oscillating mechanism 3 is used for brushing the two end faces of the vacuum interrupter, when the brushing oscillating mechanism 3 brushes one end face of the vacuum interrupter, the clamping tool 4 turns over the clamped vacuum interrupter and makes the other end face of the vacuum interrupter to be brushed correspond to the brushing oscillating mechanism, so that the brushing oscillating mechanism 3 brushes the other end face of the vacuum interrupter; the blowing mechanism 5 is used for cleaning and drying the vacuum interrupter after brushing, since the two end faces of the vacuum interrupter are brushed, the two end faces of the vacuum interrupter need to be cleaned and dried when the vacuum interrupter after brushing is cleaned and dried, therefore, when the vacuum interrupter after brushing is cleaned and dried in the blowing mechanism 5, one end face of the vacuum interrupter can be cleaned and dried first and then the other end face of the vacuum interrupter is cleaned and dried, or the blowing mechanism 5 can clean and dry the two end faces of the vacuum interrupter at the same time; the product discharging positioning mechanism 6 is used for placing the vacuum interrupter after cleaning and drying, thereby facilitating the clamping of the clamping tool 4.

[0032] When in operation, the vacuum interrupter to be brushed is placed on the product feeding positioning mechanism 2 by manual or robot, then the clamping tool 4 transfers the vacuum interrupter to above the brushing oscillating mechanism 3, the brushing oscillating mechanism 3 brushes one end face of the vacuum interrupter first, when one end face of the vacuum interrupter is brushed, the clamping tool 4 turns over the clamped vacuum interrupter, so that the other end face of the vacuum interrupter to be brushed corresponds to the brushing oscillating mechanism 3, and the brushing oscillating mechanism 3 brushes the other end face of the vacuum interrupter; when the two end faces of the vacuum interrupter are brushed, the clamping tool 4 transfers the vacuum interrupter to the blowing mechanism 5, the blowing mechanism 5 cleans the vacuum interrupter first, and then dries the cleaned vacuum interrupter; when the vacuum interrupter is dried, the clamping tool 4 transfers the dried vacuum interrupter to the product discharging positioning mechanism 6, and the vacuum interrupter on the product discharging positioning mechanism 6 is taken away by manual or robot.

[0033] In the application, since the vacuum arc-extinguishing chamber is in a cylindrical shape, in order to make the vacuum arc-extinguishing chamber stable in a fixed position before brush plating and after cleaning and drying, the product upper part positioning mechanism 2 and the product lower part positioning mechanism 6 can be fixed seats 201 directly installed on the rack 1, and the fixed seats 201 have recesses for inserting one end of the vacuum arc-extinguishing chamber, so that the vacuum arc-extinguishing chamber can be inserted into the corresponding fixed seat 201 before brush plating and after cleaning and drying, thereby making the vacuum arc-extinguishing chamber stable in a fixed position. This not only facilitates the clamping jaw tool 4 to clamp and transport the vacuum arc-extinguishing chamber to be brush plated, but also facilitates the subsequent robot to clamp and transport the vacuum arc-extinguishing chamber after cleaning and drying.

[0034] In the application, in order to make the vacuum arc-extinguishing chamber stable in a fixed position before brush plating and after cleaning and drying, a recessed installation groove can also be directly arranged on the workbench 101 surface of the rack 1, the diameter of the installation groove is matched with the diameter of the vacuum arc-extinguishing chamber, so that the vacuum arc-extinguishing chamber can be inserted into the corresponding installation groove before brush plating and after cleaning and drying. This design not only meets the use, but also makes the structure of the product upper part positioning mechanism 2 and the product lower part positioning mechanism 6 simpler and the processing mode simpler.

[0035] In the application, in order to make the workbench 101 surface of the rack 1 more tidy, the brush plating swing mechanism 3 and the cleaning and drying mechanism 5 can be directly arranged below the workbench 101 of the rack 1 when designed. Since the product upper part positioning mechanism 2 and the product lower part positioning mechanism 6 are located on the workbench 101 of the rack 1, in order to make the end of the vacuum arc-extinguishing chamber to be brush plated correspond to the brush plating swing mechanism 3, and in order to make the vacuum arc-extinguishing chamber after brush plating enter the cleaning and drying mechanism 5 for cleaning, the brush plating swing mechanism 3 and the cleaning and drying mechanism 5 each include an insertion hole 301 arranged on the workbench 101 of the rack 1, the diameter of the insertion hole 301 is slightly larger than the diameter of the vacuum arc-extinguishing chamber, and the insertion hole 301 penetrates the workbench 101 of the rack 1. When the vacuum arc-extinguishing chamber to be brush plated and the vacuum arc-extinguishing chamber after brush plating are inserted into the insertion hole 301, the end surface of the vacuum arc-extinguishing chamber to be brush plated corresponds to the brush plating swing mechanism 3, and the end surface of the vacuum arc-extinguishing chamber after brush plating is inserted into the cleaning and drying mechanism 5. Therefore, the end of the vacuum arc-extinguishing chamber to be brush plated is not affected by the brush plating material when brush plating, and the end of the vacuum arc-extinguishing chamber after brush plating is not splashed by the cleaning liquid when cleaning and drying, so that the workbench 101 of the rack 1 is more tidy.

[0036] In order to prevent the vacuum interrupter to be plated and the vacuum interrupter after plating from sliding easily in the insertion hole 301, a plurality of rubber elastic members 302 are arranged on the hole wall of the insertion hole 301. The rubber elastic members 302 are in the shape of a sector, the width of the end of the rubber elastic member 302 close to the center of the insertion hole 301 is smaller than the width of the end of the rubber elastic member 302 close to the hole wall of the insertion hole 301, the extension end of the rubber elastic member 302 is consistent with the radial direction of the insertion hole 301, the extension ends of the plurality of rubber elastic members 302 are arranged uniformly along the circumferential direction of the insertion hole 301, and the diameter of the circle formed by the extension ends of the plurality of rubber elastic members 302 is greater than the diameter of one end of the vacuum interrupter and smaller than the diameter of the vacuum interrupter. When the vacuum interrupter to be plated and the vacuum interrupter after plating are inserted into the insertion hole 301, the vacuum interrupter to be plated and the vacuum interrupter after plating will be extruded and deformed on the rubber elastic members 302, and the elastic force of the rubber elastic members 302 will clamp the vacuum interrupter to be plated or the vacuum interrupter after plating, so that the vacuum interrupter to be plated and the vacuum interrupter after plating will not fall automatically in the insertion hole 301 under the condition of no external force after being inserted into the insertion hole 301. This not only makes the end surface of the vacuum interrupter to be plated more stable during the plating process and the end surface of the vacuum interrupter after plating more stable during the cleaning and drying process, but also effectively prevents the plating material and the cleaning liquid from splashing on the surface of the workbench 101 of the rack 1 through the insertion hole 301.

[0037] In the present application, as shown in Figure 1 , Figure 2 , the plating swing mechanism 3 comprises a plating structure, a diaphragm pump 304 and a plating material storage box 303. The plating material storage box 303 is used for storing the plating material, and the diaphragm pump 304 is used for conveying the plating material in the plating material storage box 303 to the plating structure, so that the plating structure can plate the plating material on the end of the vacuum interrupter. In order to ensure that the plating structure can uniformly plate the plating material on the end surface of the vacuum interrupter, the plating structure comprises a plating head used for plating the plating material, the center of the plating head is on the same vertical line as the center of the insertion hole 301 in the plating swing mechanism 3, and the plating material storage box 303 communicates with the inlet end of the diaphragm pump 304 through a hose, and the inlet end of the diaphragm pump 304 communicates with the plating head through a hose, so that the diaphragm pump 304 can convey the plating material in the plating material storage box 303 to the plating head during operation, thereby ensuring the plating of the end surface of the vacuum interrupter by the plating head.

[0038] In order to facilitate the installation of the plating head, as shown in Figure 4 , Figure 5 , Figure 6As shown, the brush plating structure comprises a main plate 305 supported together by a plurality of support rods on the lower surface of the workbench 101 of the rack 1, and a rotatable rotating shaft 308 is installed on the main plate 305, and the upper end of the rotating shaft 308 extends to the workbench 101 of the rack 1. The brush plating head comprises a quick connector 309 installed on the upper end of the rotating shaft 308 and a brush plating material distribution head 312 fixed on the quick connector 309, a hose connected to the outlet end of the diaphragm pump 304 is in communication with the inlet end of the brush plating material distribution head 312, and the outlet end of the brush plating material distribution head 312 is covered with a felt brush plating head 313, so that the brush plating material transported by the diaphragm pump 304 enters the brush plating material distribution head 312 and is sent out through the brush plating material distribution head 312 and adheres to the felt brush plating head 313, so that when the felt brush plating head 313 contacts the end of the vacuum interrupter, the brush plating material adhering to the felt brush plating head 313 adheres to the end surface of the vacuum interrupter, thereby completing the brush plating of the end surface of the vacuum interrupter.

[0039] In the present application, the rotation of the rotating shaft 308 is not 360° rotation, but reverse rotation after a certain angle of rotation, so that even if the brush plating structure needs to be connected with the hose connected to the outlet end of the diaphragm pump 304, it will not cause the hose to be wound, knotted and other problems, and will not affect the rotation of the rotating shaft 308 and the brush plating of the end surface of the vacuum interrupter.

[0040] In the present application, as shown, Figure 6 The brush plating material distribution head 312 comprises a main channel 3121 and a plurality of branch channels 3122, the diameter of the middle part of the brush plating material distribution head 312 gradually increases to the diameter of the end of the brush plating material distribution head 312 close to the felt brush plating head 313, and the center axis of the main channel 3121 is on the same straight line as the center axis of the brush plating material distribution head 312, the inlet ends of the plurality of branch channels 3122 are in communication with the main channel 3121, and the outlet ends of the plurality of branch channels 3122 are uniformly distributed on the end face of the end of the brush plating material distribution head 312 close to the felt brush plating head 313, so that the brush plating material sent out through the brush plating material distribution head 312 is uniformly distributed on the felt brush plating head 313, and the plating layer brushed on the end surface of the vacuum interrupter by the subsequent felt brush plating head 313 is more uniform.

[0041] In order to facilitate the connection between the brush plating material shunt head 312 and the quick connector 309, the quick connector 309 is provided with a connector hole one 3091 near the end close to the brush plating material shunt head 312, the brush plating material shunt head 312 is directly inserted into the connector hole one 3091 during installation, the depth of the connector hole one 3091 is greater than the length of the brush plating material shunt head 312 inserted into the connector hole one 3091, at this time, the connector hole one 3091 is in communication with the main channel 3121 in the brush plating material shunt head 312; in order to ensure the sealing between the brush plating material shunt head 312 and the quick connector 309, the insertion end of the brush plating material shunt head 312 is also embedded with a plurality of sealing rings, the plurality of sealing rings are uniformly spaced along the axis direction of the brush plating material shunt head 312, and the sealing of the connection between the quick connector 309 and the brush plating material shunt head 312 is better through the cooperation of the plurality of sealing rings. In order to facilitate the communication between the hose connected to the outlet end of the diaphragm pump 304 and the main channel 3121 in the brush plating material shunt head 312, the quick connector 309 is also provided with a through hole in communication with the connector hole one 3091, the hose connected to the outlet end of the diaphragm pump 304 is in communication with the through hole, so that the brush plating material transported by the diaphragm pump 304 first enters the connector hole one 3091 through the through hole and then enters the main channel 3121, which not only ensures the normal supply of the brush plating material, but also facilitates the connection between the hose and the quick connector 309.

[0042] In order to avoid damage to the brush plating head caused by collision when the clamping jaw tool 4 clamps the vacuum interrupter to make its end face contact with the brush plating material shunt head 312, the end of the quick connector 309 away from the brush plating material shunt head 312 is also provided with a connector hole two 3092, the central axis of the connector hole two 3092 is on the same straight line as the central axis of the connector hole one 3091, and the connector hole two 3092 is not in communication with the connector hole one 3091; at the same time, the connector hole two 3092 is also installed with a compression spring 310, the upper end of the rotating shaft 308 is inserted into the connector hole two 3092, and the upper end of the rotating shaft 308 abuts against the compression spring 310, so that when the clamping jaw tool 4 clamps the vacuum interrupter to make its end face contact with the felt brush plating head 313, the force exerted by the clamping vacuum interrupter on the felt brush plating head 313 is transmitted to the compression spring 310 through the brush plating material shunt head 312 and the quick connector 309, and through the compression of the compression spring 310, the felt brush plating head 313, the brush plating material shunt head 312 and the quick connector 309 can move axially on the rotating shaft 308 together, thereby effectively preventing the felt brush plating head 313, the brush plating material shunt head 312 and the quick connector 309 from being damaged due to expansion. Since the rotating shaft 308 needs to drive the quick connector 309, the brush plating material shunt head 312 and the felt brush plating head 313 to rotate synchronously while rotating, therefore, after the upper end of the rotating shaft 308 is inserted into the quick connector 309, it is necessary to ensure that the quick connector 309 cannot rotate relative to the rotating shaft 308 while ensuring that the quick connector 309 can move axially on the rotating shaft 308.

[0043] In order to ensure that the quick plug 309 is axially movable but not rotatable on the rotating shaft 308, the rotating shaft 308 is designed to have a cut surface 3081 at one end of the rotating shaft 308 inserted into the plug hole two 3092, the length of the cut surface 3081 is not less than the distance of the axial displacement of the quick plug 309 on the rotating shaft 308; at the same time, an adjusting bolt is installed on the quick plug 309, the axial direction of the adjusting bolt is consistent with the radial direction of the rotating shaft 308, and the tail of the adjusting bolt is in clearance fit with the cut surface 3081, at this time, through the fit of the tail of the adjusting bolt and the cut surface 3081, the quick plug 309 is not rotatable but axially movable on the rotating shaft 308. Of course, in the present application, the end of the rotating shaft 308 inserted into the plug hole two 3092 can also be directly provided as a polygonal prism, and the fit of the edge surface on the plug end of the rotating shaft 308 and the tail of the adjusting bolt can also achieve that the quick plug 309 is axially movable but not rotatable on the rotating shaft 308.

[0044] Since the felt brush plating head 313 is easy to overflow the brush plating material during the process of brushing and plating the end face of the vacuum arc-extinguishing chamber, in order to facilitate the collection of the part of the brush plating material, the lower end of the quick plug 309 is also covered with a protective cover 311, the protective cover 311 is trumpet-shaped, so that the brush plating material overflowing from the felt brush plating head 313 can flow along the outer wall of the brush plating material distribution head 312 and the outer wall of the quick plug 309 to the protective cover 311; at the same time, the brush plating oscillating mechanism 3 also includes a liquid receiving box 318 installed on the main machine plate 305, the liquid receiving box 318 is in butt joint with the outer edge of the protective cover 311, so that the brush plating material flowing to the protective cover 311 can flow uniformly along the outer wall thereof and fall into the liquid receiving box 318, thereby collecting the brush plating material overflowing from the felt brush plating head 313. In the present application, the bottom of the rack 1 is also provided with a plating layer material recycling box 319, the installation height of the plating layer material recycling box 319 is lower than that of the liquid receiving box 318, and a hose is used to communicate the plating layer material recycling box 319 with the liquid receiving box 318, so that the brush plating material collected in the liquid receiving box 318 can automatically enter into the plating layer material recycling box 319 through the self-weight along the hose.

[0045] In order to avoid the brush plating material flowing along the outer wall of the shunt head 312 and the outer wall of the quick connector 309 from entering the rotating shaft 308, the upper end of the quick connector 309 is designed to have the same shape as the lower end of the quick connector 309, or the shape of the upper end of the quick connector 309 is different from that of the lower end of the quick connector 309, but the size of the upper end of the quick connector 309 is as large as possible than that of the lower end of the quick connector 309. After the protective cover 311 is installed at the lower end of the quick connector 309, the brush plating material flowing along the outer wall of the quick connector 309 cannot enter the gap between the protective cover 311 and the outer wall of the quick connector 309, so that the protective cover 311 can effectively separate the outer wall of the quick connector 309 into two parts, thereby effectively avoiding the brush plating material flowing along the outer wall of the quick connector 309 from entering the rotating shaft 308, and the collection effect of the brush plating material is better.

Figure 8As shown, the blowing mechanism 5 further comprises a collecting box 501 installed below the rack 1, and the collecting box 501 is located below the inserting hole 301 in the blowing mechanism 5, so that after the brush plated vacuum interrupter is inserted into the inserting hole 301 in the blowing mechanism 5, the end of the vacuum interrupter is located in the collecting box 501; meanwhile, the high-pressure water nozzle 502 and the high-pressure air nozzle 503 are further installed in the collecting box 501, and the installation height and installation position of the high-pressure water nozzle 502 and the high-pressure air nozzle 503 in the collecting box 501 can be determined according to the insertion of the vacuum interrupter into the inserting hole 301 in the blowing mechanism 5, and the high-pressure water nozzle 502 and the high-pressure air nozzle 503 can be one or more under the condition of ensuring the cleaning and drying of the end face of the vacuum interrupter, but when the high-pressure water nozzle 502 and the high-pressure air nozzle 503 are installed, the outlet end of the high-pressure water nozzle 502 and the outlet end of the high-pressure air nozzle 503 are both inclined upward, and the outlet end of the high-pressure water nozzle 502 and the outlet end of the high-pressure air nozzle 503 are both correspond to below the center of the inserting hole 301 in the blowing mechanism 5, so that after the vacuum interrupter to be cleaned and dried is inserted into the inserting hole 301 in the blowing mechanism 5, the outlet end of the high-pressure water nozzle 502 and the outlet end of the high-pressure air nozzle 503 are both correspond to the end face of the vacuum interrupter inserted into the inserting hole 301 in the blowing mechanism 5, so that the cleaning and drying effect of the end face of the vacuum interrupter is better.

[0048] In the present application, in order to ensure the operation of the high-pressure water nozzle 502 and the high-pressure air nozzle 503, the inlet end of the high-pressure water nozzle 502 is connected with a high-pressure water pump through a pipeline system, and the inlet end of the high-pressure water pump is communicated with a water tank; the high-pressure air nozzle 503 is communicated with a vacuum pump through a pipeline system. In the present application, in order to facilitate the subsequent discharge of the cleaning liquid in the collecting box 501, a liquid discharge pipeline is further connected to the collecting box 501.

[0049] In the present application, in order to reduce the cost of the clamping jaw tool 4 as much as possible, as shown in the drawings, Figure 1 、 Figure 2 、 Figure 7As shown, the product upper positioning mechanism 2, the brush plating swing mechanism 3, the blowing and washing mechanism 5, and the product lower positioning mechanism 6 can be arranged along the length direction of the workbench 101 on the rack 1, so that the product upper positioning mechanism 2, the brush plating swing mechanism 3, the blowing and washing mechanism 5, and the product lower positioning mechanism 6 are located on the same straight line. Meanwhile, the clamping jaw tool 4 comprises a mounting seat 403 which can move up and down and left and right, and a rotating device 404 is installed on the mounting seat 403. The rotating device 404 can be a rotating motor or a pneumatic rotating device 404. A pneumatic clamping jaw 405 is installed on the output end of the rotating device 404. The pneumatic clamping jaw 405 clamps the vacuum interrupter and drives the pneumatic clamping jaw 405 to rotate through the rotating device 404, so that the vacuum interrupter clamped by the pneumatic clamping jaw 405 rotates. After one end of the vacuum interrupter is brushed or washed and dried, the vacuum interrupter is pulled out from the insertion hole 301 in the brush plating swing mechanism 3 and the insertion hole 301 in the blowing and washing mechanism 5 through the up and down movement of the mounting seat 403. Then, the vacuum interrupter clamped by the pneumatic clamping jaw 405 is rotated again, and the end of the vacuum interrupter which has not been brushed or washed and dried is inserted into the insertion hole 301 in the brush plating swing mechanism 3 and the insertion hole 301 in the blowing and washing mechanism 5 through the up and down movement of the mounting seat 403, so that the end of the vacuum interrupter which has not been brushed or washed and dried is brushed or washed and dried.

[0050] In order to ensure the up and down and left and right movement of the mounting seat 403, the clamping jaw tool 4 further comprises a linear motor one 401 which extends in a horizontal direction and is arranged on the rack 1. The output end of the linear motor one 401 is provided with a linear motor two 402 which extends in a vertical direction. The mounting seat 403 is fixedly installed on the linear motor two 402. That is, the linear motor one 401 can drive the linear motor two 402 and the mounting seat 403 to move left and right on the rack 1, and the linear motor two 402 can drive the mounting seat 403 to move up and down on the rack 1, so that the mounting seat 403 can move up and down and left and right on the rack 1, and the transfer of the vacuum interrupter is realized.

[0051] Of course, in the present application, the product upper positioning mechanism 2, the brush plating swing mechanism 3, the blowing and washing mechanism 5, and the product lower positioning mechanism 6 can be arranged on the workbench 101 of the rack 1 at will. In this case, only a mechanical hand is needed to replace the linear motor one 401 and the linear motor two 402. The mechanical hand can drive the mounting seat 403 to move in the X-axis, Y-axis, and Z-axis directions, so that the transfer of the vacuum interrupter between the product upper positioning mechanism 2, the brush plating swing mechanism 3, the blowing and washing mechanism 5, and the product lower positioning mechanism 6 is realized, and the rotation of the vacuum interrupter in the brush plating swing mechanism 3 and the blowing and washing mechanism 5 is realized.

[0052] In order to make the clamping of the vacuum interrupter by the pneumatic clamping jaw 405 more stable, a telescopic piece (not shown in the figure) that can vertically extend and retract is also installed on the mounting seat 403, the telescopic piece is selected from a hydraulic cylinder, an air cylinder or an electronic telescopic rod, and an extension arm 406 is installed at the output end of the telescopic piece, the extension arm 406 extends upwards of the clamping jaw, and a telescopic spring 407 is also installed below the extension end of the extension arm 406, and an electrode contact 408 is fixedly installed at the extension end of the telescopic spring 407; when the pneumatic clamping jaw 405 clamps the vacuum interrupter, the center of the electrode contact 408 is on the same straight line as the central axis of the vacuum interrupter.

[0053] In the present application, the material of the electrode contact 408 is copper, when the electrode contact 408 is installed, the electrode contact 408 is connected with the negative electrode of the current and voltage loading device through a negative electrode line, and the positive electrode of the current and voltage loading device is in contact with the brush plating material in the brush plating material storage box 303 through a positive electrode line. When the pneumatic clamping jaw 405 clamps the vacuum interrupter for brush plating, the electrode contact 408 abuts against the end face of the vacuum interrupter, the current and voltage loading device loads current and voltage, in the silver ion solution with current, the positive and negative charges carry silver ions to be attached to the end face of the vacuum interrupter that needs to be brush plated, and by controlling the time and intensity of the current, the thickness of the plating layer can reach the required thickness.

[0054] By connecting the telescopic spring 407 between the electrode contact 408 and the extension arm 406, the electrode contact 408 can be kept in continuous pressure with the end face of the vacuum interrupter, so that stable conduction plating during the brush plating process is realized.

[0055] When it is needed to clamp the vacuum interrupter on the product upper piece positioning mechanism 2, the linear motor two 402 drives the mounting seat 403, the telescopic piece, the rotating device 404, the pneumatic clamping jaw 405, the extension arm 406, the telescopic spring 407 and the electrode contact 408 to move downward synchronously, when the pneumatic clamping jaw 405 corresponds to the vacuum interrupter placed on the product upper piece positioning mechanism 2, the telescopic piece is retracted, the telescopic piece drives the extension arm 406, the telescopic spring 407 and the electrode contact 408 to move downward synchronously, so that the electrode contact 408 is pressed on the vacuum interrupter placed on the product upper piece positioning mechanism 2, then the pneumatic clamping jaw 405 clamps the vacuum interrupter placed on the product upper piece positioning mechanism 2, then the linear motor two 402 drives the mounting seat 403, the telescopic piece, the rotating device 404, the pneumatic clamping jaw 405, the extension arm 406, the telescopic spring 407, the electrode contact 408 and the clamped vacuum interrupter to move upward synchronously, at this time, the elastic force of the telescopic spring 407 makes the upper end of the vacuum interrupter abut against the electrode contact 408, and through the cooperation of the pneumatic clamping jaw 405 and the electrode contact 408, the clamped vacuum interrupter is more stable.

[0056] When the vacuum arc-extinguishing chamber needs to be rotated after being clamped by the pneumatic clamping jaw 405, the extension arm 406, the extension spring 407 and the electrode contact 408 are driven by the extension member to move upward synchronously, so that the electrode contact 408 gradually moves away from the end face of the vacuum arc-extinguishing chamber, and finally the electrode contact 408 loses the pressure on the end face of the vacuum arc-extinguishing chamber, at this time, the rotating device 404 drives the pneumatic clamping jaw 405 and the clamped vacuum arc-extinguishing chamber to rotate; after the pneumatic clamping jaw 405 drives the clamped vacuum arc-extinguishing chamber to rotate by 180 degrees, the extension member is retracted, and the extension arm 406, the extension spring 407 and the electrode contact 408 are driven by the extension member to move downward synchronously, so that the electrode contact 408 presses the vacuum arc-extinguishing chamber clamped by the pneumatic clamping jaw 405, and the clamped vacuum arc-extinguishing chamber is rotated.

[0057] In the present application, the extension member can also be directly installed on the workbench 101 of the rack 1, at this time, since the extension member cannot move in the X-axis direction, when the extension arm 406 is installed, the electrode contact 408 needs to be ensured to be located above the insertion hole 301 of the brush plating swing mechanism 3, and the center of the electrode contact 408 is on the same vertical line as the center of the insertion hole 301 of the brush plating swing mechanism 3, at this time, the pneumatic clamping jaw 405 can normally clamp the vacuum arc-extinguishing chamber, and the end face of the vacuum arc-extinguishing chamber can be pressed by the pneumatic clamping jaw 405 during the brush plating process, and the rotating device 404 can normally drive the pneumatic clamping jaw 405 and the clamped vacuum arc-extinguishing chamber to rotate under the condition that the pneumatic clamping jaw 405 clamps the vacuum arc-extinguishing chamber.

[0058] In order to avoid the pneumatic clamping jaw 405 from slipping with the vacuum arc-extinguishing chamber, the clamping surface of the pneumatic clamping jaw 405 is provided with anti-skid lines; at the same time, in order to avoid the pneumatic clamping jaw 405 from damaging the surface of the vacuum arc-extinguishing chamber when clamping the vacuum arc-extinguishing chamber, a rubber pad layer can also be arranged on the clamping surface of the pneumatic clamping jaw 405, at this time, the anti-skid lines are arranged on the rubber pad layer.

[0059] Based on the above-mentioned brush plating device for the silver layer on the end face of the vacuum arc-extinguishing chamber, the present application also provides a brush plating method, which comprises the following steps: Step 1, manually or robotically insert the vacuum interrupter to be brush plated into the fixed seat 201 of the product positioning mechanism 2, the linear motor one 401 drives the linear motor two 402, the mounting seat 403, the telescopic part, the rotating device 404, the pneumatic clamp jaw 405, the extension arm 406, the telescopic spring 407, and the electrode contact 408 to move horizontally synchronously; when the pneumatic clamp jaw 405 and the electrode contact 408 are above the vacuum interrupter placed on the fixed seat 201, the linear motor one 401 stops driving, and the linear motor two 402 drives the mounting seat 403, the telescopic part, the rotating device 404, the pneumatic clamp jaw 405, the extension arm 406, the telescopic spring 407, and the electrode contact 408 to move downward synchronously; when the pneumatic clamp jaw 405 corresponds to the vacuum interrupter, and the electrode contact 408 abuts against the top of the vacuum interrupter on the fixed seat 201, and the telescopic spring 407 is compressed, the linear motor two 402 stops driving, and the pneumatic clamp jaw 405 clamps the vacuum interrupter on the fixed seat 201; after the vacuum interrupter on the fixed seat 201 is clamped and fixed, the linear motor two 402 drives the clamped vacuum interrupter to move upward synchronously, so that the lower end of the vacuum interrupter exits the fixed seat 201; After the linear motor two 402 drives the clamped vacuum interrupter to move upward to a certain height, the linear motor two 402 stops driving; the linear motor one 401 drives the clamped vacuum interrupter to move horizontally synchronously, and when the vacuum interrupter is above the insertion hole 301 in the brush plating swing mechanism 3, the linear motor two 402 drives the clamped vacuum interrupter to move downward, and inserts the clamped vacuum interrupter into the insertion hole 301 in the brush plating swing mechanism 3; when the lower end surface of the clamped vacuum interrupter contacts the felt brush plating head 313, the linear motor two 402 stops driving; Then, the diaphragm pump 304 is started, and the diaphragm pump 304 delivers the brush plating material in the brush plating material storage box 303 into the insertion hole one 3091 of the quick connector 309. With the continuous delivery of the diaphragm pump 304, the brush plating material in the insertion hole one 3091 is applied to the felt brush plating head 313 through the main channel 3121 and the branch channel 3122. The stepping motor 314 is started, and the stepping motor 314 drives the driving pulley 315 to rotate forward by 60 degrees.

The driven pulley 316 drives the rotating shaft 308 to rotate, and the rotating shaft 308 drives the quick connector 309, the brush plating material distribution head 312 and the felt brush plating head 313 to rotate synchronously. The brush plating material attached to the felt brush plating head 313 is attached to the end face of the vacuum interrupter. After the stepping motor 314 rotates forward by 60 degrees, the stepping motor 314 drives the driving pulley 315 to rotate reversely by 60 degrees. The driving pulley 315 drives the driven pulley 316 to rotate through the synchronous belt 317. The driven pulley 316 drives the rotating shaft 308 to rotate, and the rotating shaft 308 drives the quick connector 309, the brush plating material distribution head 312 and the felt brush plating head 313 to rotate synchronously. The brush plating material attached to the felt brush plating head 313 is attached to the end face of the vacuum interrupter. The end of the vacuum interrupter is completed with the brush plating, and the diaphragm pump 304 is stopped. The linear motor two 402 drives the clamped vacuum interrupter to move upward, so that the clamped vacuum interrupter is away from the felt brush plating head 313, and the clamped vacuum interrupter exits the insertion hole 301 in the brush plating swing mechanism 3. The extension arm 406, the extension spring 407 and the electrode contact 408 are driven by the extension member to move upward synchronously, so that the electrode contact 408 is gradually away from the end face of the vacuum interrupter, and finally the electrode contact 408 loses the pressure on the end face of the vacuum interrupter. At this time, the rotary device 404 drives the pneumatic clamping jaw 405 and the clamped vacuum interrupter to rotate, and the rotary device 404 drives the pneumatic clamping jaw 405 and the clamped vacuum interrupter to rotate by 180 degrees, so that the end of the vacuum interrupter without the brush plating layer faces downward, and the end of the vacuum interrupter with the brush plating layer faces upward. The extension member is retracted, and the extension member drives the electrode contact 408 to move downward, so that the electrode contact 408 is pressed on the vacuum interrupter clamped by the pneumatic clamping jaw 405. The linear motor two 402 drives the clamped vacuum interrupter to move downward, so that the lower end face of the clamped vacuum interrupter is in contact with the felt brush plating head 313, and the linear motor two 402 is stopped. The diaphragm pump 304 is started, and the diaphragm pump 304 delivers the brush plating material in the brush plating material storage box 303 to the felt brush plating head 313. The stepping motor 314 is started, and the stepping motor 314 drives the driving pulley 315 to rotate forward by 60 degrees and then reversely by 60 degrees, so that the other end of the vacuum interrupter is completed with the brush plating.

[0060] Step 2, after the vacuum interrupter is plated on both ends, the linear motor two 402 drives the vacuum interrupter to move upwards, so that the vacuum interrupter exits the insertion hole 301 of the brushing and swinging mechanism 3; the linear motor one 401 drives the vacuum interrupter to move horizontally synchronously, and when the vacuum interrupter is above the insertion hole 301 in the blowing and washing mechanism 5, the linear motor two 402 drives the vacuum interrupter to move downwards and insert into the insertion hole 301 in the blowing and washing mechanism 5; when the lower end of the vacuum interrupter extends into the collection box 501, the linear motor two 402 stops; the high-pressure water jet 502 starts to spray water, and the water sprayed by the high-pressure water jet 502 acts on the lower end surface of the vacuum interrupter, so as to clean the lower end surface of the vacuum interrupter; after the lower end surface of the vacuum interrupter is cleaned, the high-pressure water jet 502 stops spraying water; the high-pressure air jet 503 starts to blow air, and the compressed air sprayed by the high-pressure air jet 503 acts on the lower end surface of the vacuum interrupter, so as to dry the lower end surface of the vacuum interrupter; after the lower end surface of the vacuum interrupter is dried, the high-pressure air jet 503 stops blowing air. The linear motor two 402 drives the vacuum interrupter to exit the insertion hole 301 in the blowing and washing mechanism 5; the telescopic part drives the electrode contact 408 to move upwards synchronously, so that the electrode contact 408 moves away from the end surface of the vacuum interrupter, and then the rotating device 404 drives the pneumatic clamp jaw 405 and the vacuum interrupter to rotate, so that the vacuum interrupter is rotated by 180 degrees. The linear motor two 402 drives the vacuum interrupter to move downwards, and after the lower end of the vacuum interrupter extends into the collection box 501 through the insertion hole 301, the linear motor two 402 stops; the high-pressure water jet 502 starts to spray water on the lower end surface of the vacuum interrupter, and after the lower end surface of the vacuum interrupter is cleaned, the high-pressure air jet 503 starts to blow air, and the high-pressure air jet 503 dries the lower end surface of the vacuum interrupter.

[0062] In the present application, the vacuum interrupter clamped by the pneumatic jaw 405 is directly driven by the linear motor 401 to enter the insertion hole 301 in the brushing mechanism 3 after the brushing layer is completed and the vacuum interrupter is driven by the linear motor 402 to exit the insertion hole 301 in the brushing mechanism 3, and then the vacuum interrupter is inserted into the insertion hole 301 in the brushing mechanism 3 by the driving of the linear motor 402, and then the vacuum interrupter is cleaned and dried by the high-pressure water jet 502 and the high-pressure air jet 503 in the brushing mechanism 5. After the vacuum interrupter is cleaned and dried, the vacuum interrupter is driven by the linear motor 402 to exit the insertion hole 301 in the brushing mechanism 3, and then the vacuum interrupter is driven by the linear motor 401 to enter the insertion hole 301 in the brushing mechanism 3, and then the electrode contact 408 is loosened by the extension of the telescopic member, and then the vacuum interrupter is rotated by 180 degrees by the driving of the rotating device 404, so that the vacuum interrupter is rotated by 180 degrees, and then the vacuum interrupter is driven by the linear motor 401 and the linear motor 402 to brush the layer on the other end of the vacuum interrupter, and then the vacuum interrupter is cleaned and dried by the linear motor 401 and the linear motor 402.
