Description

Technical Field

[0001] The invention belongs to the technical field of electric meter production, and in particular relates to a mechanical arm for producing intelligent electric energy meters. Background Art

[0002] A Chinese patent with authorization announcement number CN213412036U discloses a robotic arm for a smart electric energy meter production line, which controls a slider to move to the top of an electric energy meter conveying platform through a slide rail, and a first hydraulic cylinder is started to drive a mounting plate to move downward, so that a negative pressure suction cup is adsorbed on the electric energy meter cover, and then the output shaft of the first hydraulic cylinder is retracted, driving the electric energy meter cover to move upward to open the cover; then the slide rail controls the slider to move to just above the lower nameplate, thereby driving the negative pressure suction cup to move to just above the lower nameplate, and then the first hydraulic cylinder is started to drive the mounting plate to move downward, so that the negative pressure suction cup is pressed against the lower nameplate, and the negative pressure pump is started to produce negative pressure in the negative pressure suction cup. Generate negative pressure to adsorb the lower nameplate on the negative pressure suction cup; start the second hydraulic cylinder, and the output shaft of the second hydraulic cylinder extends, so that the pressure block presses down the two sides of the lower nameplate; the output shaft of the first hydraulic cylinder retracts, driving the mounting plate to move up; the slide rail starts to drive the slider to move above the electric energy meter conveying platform, and the first hydraulic cylinder starts again, and the first hydraulic cylinder drives the mounting plate to move down, so that the lower nameplate is attached to the electric energy meter, and then the output shaft of the second hydraulic cylinder retracts, the pressure block no longer presses the lower nameplate, and the lower nameplate unfolds, thereby being stuck in the lower nameplate mounting groove of the electric energy meter, and at the same time, the negative pressure pump inflates the negative pressure suction cup in the opposite direction, so that the negative pressure suction cup releases the lower nameplate, thereby realizing the mechanized assembly of the lower nameplate. The above device has the following drawbacks: 1) The lower nameplate is transferred back and forth through components such as slide rails and sliders, and the work efficiency is low; 2) Although the pressure block presses down the two sides of the lower nameplate when the negative pressure suction cup sucks the lower nameplate, when the first hydraulic cylinder drives the lower nameplate to move to the lower nameplate installation groove of the electric energy meter through the mounting plate, it uses the lower nameplate's own elasticity to snap into the lower nameplate installation groove of the electric energy meter, which may cause the lower surface of the lower nameplate to not completely fit with the surface of the lower nameplate installation groove, that is, the lower nameplate is not completely snapped into the lower nameplate installation groove, causing the lower nameplate to fall off from the lower nameplate installation groove during subsequent processing of the electric energy meter, affecting the production efficiency of the electric energy meter. Therefore, it is urgent to study a robot arm for the production of intelligent electric energy meters to solve the above problems. Summary of the invention

Specific embodiment 2:

[0031] Based on the specific embodiment 1, Figure 2-Figure 6As shown, the feeding assembly 2 includes a storage box 201 with an open structure at the upper part; the storage box 201 is fixed to a side surface of the hanging arm 1 through a vertically arranged mounting frame 202; a discharge channel 2011 is provided at the lower edge of a side wall of the storage box 201 close to the hanging arm 1; the discharge channel 2011 can only allow one lower nameplate to pass through at a time; a shift plate 203 is horizontally fixed at the upper edge of the outer port of the discharge channel 2011; the shift plate 203 is arranged just above the rotating assembly 5; a protrusion 2012 of a rectangular structure is integrally formed at the lower edge of a side wall of the storage box 201 away from the hanging arm 1; the protrusion 2012 has a guide channel 2013 corresponding to the discharge channel 2011; a horizontally arranged push plate 204 is slidably inserted in the guide channel 2013; the thickness of the push plate 204 is consistent with the thickness of the lower nameplate; the bottom wall of the storage box 201 is provided with a directional passage Channel 2014; the opposite ends of the directional channel 2014 are respectively connected with the discharge channel 2011 and the guide channel 2013; a guide protrusion 2041 corresponding to the directional channel 2014 is horizontally fixed on the lower surface of the push plate 204; the guide protrusion 2041 slides in the directional channel 2014; a first support block 205 is provided on one side of the storage box 201; the first support block 205 is fixed on one side of the support strip 4; a horizontally arranged first transmission shaft 206 is rotatably inserted on the first support block 205; the length direction of the first transmission shaft 206 is parallel to the length direction of the directional channel 2014; a cylindrical cam 207 is coaxially fixed to one end of the first transmission shaft 206; a driving column 208 is slidably inserted in the working groove of the cylindrical cam 207; one end of the driving column 208 is vertically fixed to an end of the guide protrusion 2041 close to the discharge channel 2011. When in use, multiple lower nameplates are stacked in the storage box 201, and the cylindrical cam 207 is driven to rotate by rotating the first transmission shaft 206, so that the driving column 208 drives the push plate 204 to slide along the length direction of the directional channel 2014 via the guide protrusion 2041, thereby pushing the lower nameplate located at the bottom of the storage box 201 out of the storage box 201 through the discharge channel 2011, thereby realizing the feeding of the lower nameplate. Specific embodiment three:

[0033] Based on the specific embodiment 2, Figure 2 and Figure 7As shown, the rotating assembly 5 includes a movable seat 501 with a U-shaped structure; the movable seat 501 is arranged between the two side support strips 4; the two opposite side arms of the movable seat 501 are horizontally fixed with rotating shafts 502; the two rotating shafts 502 are respectively rotatably connected to the lower ends of the two side support strips 4; one end of a rotating shaft 502 is coaxially fixed to the output shaft of a servo motor 503; the servo motor 503 is horizontally fixed to the other side support strip 4. When in use, the servo motor 503 drives the movable seat 501 to rotate 180° forward through the rotating shaft 502, so as to cause the negative pressure suction box 7 to rotate from the bottom of the rotating assembly 5 to between the feeding assembly 2 and the rotating assembly 5. After the material is taken, the servo motor 503 drives the movable seat 501 to rotate 180° reversely through the rotating shaft 502, so as to rotate the negative pressure suction box 7 from between the feeding assembly 2 and the rotating assembly 5 to the bottom of the rotating assembly 5.

[0034] Among them Figure 3-Figure 4 As shown, a limit assembly 9 is installed below the shift plate 203; the limit assembly 9 includes a pair of connecting shafts 901 horizontally arranged below the opposite side edges of the shift plate 203; the length direction of the connecting shaft 901 is arranged parallel to the length direction of the directional channel 2014; a limit plate 902 is fixed on the connecting shaft 901; a storage space for the lower nameplate is formed between the limit plate 902 and the shift plate 203; one end of the connecting shaft 901 is rotatably connected to the storage box 201; the other end of the connecting shaft 901 is rotatably sleeved with a mounting block 903; the mounting block 903 is fixed on the lower surface of the shift plate 203; a surface of the mounting block 903 is connected to a torsion spring 904; one end of the torsion spring 904 is connected to the circumferential outer wall of the connecting shaft 901; the torsion spring 904 is sleeved on the outer periphery of the connecting shaft 901. When the lower nameplate is pushed out of the storage box 201 through the discharge channel 2011, the lower nameplate moves to the accommodating space formed between the limiting plate 902 and the shift plate 203. At this time, the lower nameplate is overlapped on the limiting plate 902 to form a waiting state for material collection; when the negative pressure suction nozzle 701 sucks the lower nameplate in the waiting state for material collection, the lifting assembly 6 drives the negative pressure suction nozzle 701 to move downward through the negative pressure vacuum box 7, causing the limiting plate 902 to rotate, and finally realizes that the sucked lower nameplate is separated from between the limiting plate 902 and the shift plate 203, and then the limiting plate 902 is reset under the torsion of the torsion spring 904, thereby ensuring the continuous feeding of the lower nameplate.

[0035] Among them Figure 2 , Figure 6 and Figure 7As shown, the first transmission shaft 206 is connected to the other rotating shaft 502 through a transmission assembly 10; the transmission assembly 10 includes a second support block 1001 fixed on a side support strip 4; a vertically arranged second transmission shaft 1002 is rotatably inserted on the second support block 1001; a transmission worm 1003 is coaxially fixed to the upper end of the second transmission shaft 1002; a transmission worm wheel 1004 is meshed on the transmission worm 1003; the transmission worm wheel 1004 is coaxially fixed to the other end of the first transmission shaft 206; a first bevel gear 1005 is horizontally fixed to the lower end of the second transmission shaft 1002; a second bevel gear 1006 is meshed on the first bevel gear 1005; the second bevel gear 1006 is fixed to one end of the other rotating shaft 502. When the negative pressure suction box 7 is below the rotating assembly 5, the pushing plate 204 is located in the guide channel 2013; when the negative pressure suction box 7 is rotated by the rotating assembly 5 from the bottom of the rotating assembly 5 to between the feeding assembly 2 and the rotating assembly 5, the first transmission shaft 206 is driven to rotate by the second bevel gear 1006, the first bevel gear 1005, the transmission worm 1003, the second transmission shaft 1002 and the transmission worm gear 1004, so that the pushing plate 204 pushes the lower nameplate located at the bottom of the storage box 201 out of the storage box 201 through the discharge channel 2011; when the negative pressure suction box 7 is above the rotating assembly 5 (at this time the negative pressure suction nozzle 701 is in a vertical state), the pushing plate 204 also completes the pushing action, that is, at this time the pushed out lower nameplate is already in the accommodating space formed between the limit plate 902 and the shift plate 203, and then the negative pressure suction nozzle 701 starts to suck the material and performs subsequent actions. Specific embodiment four:

[0037] Based on the specific embodiment 3, Figure 7-Figure 8 As shown, the lifting assembly 6 includes a first cylinder 601 fixed on the middle arm of the movable seat 501; the first cylinder 601 is a conventional component in this field; the telescopic direction of the output end of the first cylinder 601 is arranged parallel to the length direction of the side arm of the movable seat 501; the negative pressure vacuum box 7 is fixed on the output end of the first cylinder 601.
