Description

Technical Field

[0001] The invention relates to the technical field of shielding ring assembly, in particular to a shielding ring component and an assembly device thereof. Background Art

[0002] The shielding ring is a ring-shaped protective hardware that prevents other hardware or components within the shielding range from experiencing corona.

[0003] The prior art discloses a Chinese patent with application number CN202211627826.1, which is a tooling for medium-frequency heat treatment of shielding rings in the inner cavity of a drive shaft bell-shaped shell. It discloses fixing the hollow shielding ring on the sensor bracket, eliminating the need to manually install the shielding ring each time the bell-shaped shell is subjected to medium-frequency heat treatment, which is conducive to avoiding the risk of missing the shielding ring.

[0004] However, in the prior art, when assembling the shielding ring, due to the special shape of the shielding ring, it is impossible to perform rapid and continuous assembly operations on it, and because the shielding ring requires screws to fix its components during assembly, the components are easily misaligned after contact, resulting in subsequent difficulties in installation.

The side wall of the magnetic attraction port is used for magnetically attracting screws, and the magnetic attraction port is hexagonal and adapted to the screws.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. By opening the electric slider, the present invention can drive the annular pipe to rotate and adjust on the arc-shaped support, so as to quickly dock the middle frame and the semi-circular plate. When the arc-shaped support holds annular pipes with different diameters, rotate the threaded rotating rod. When the threaded rotating rod rotates, it drives the threaded ring above it to rotate. When the threaded ring rotates, the lifting ring outside it performs lifting operations. When the lifting ring rises and falls, it pushes and pulls the I-shaped frame through the pull plate, so as to make the arc-shaped supports above multiple I-shaped frames approach or move away from each other, thereby realizing the holding of annular pipes with different diameters, and then completing the subsequent docking.

[0020] 2. By rotating the hook plate to hook the outer wall of the annular pipe, and at the same time, under the action of the spring, the L-shaped plate slides in the chute in the direction away from the annular pipe. At this time, the annular pipe is fixed under the action of multiple hook plates, avoiding the sliding and offset of the annular pipe placed on the arc-shaped support during the rotation of the multi-station circular plate, thereby affecting the subsequent assembly operation.

[0021] 3. The setting of the central platform in the present invention facilitates the placement of the lower part of the middle frame. At the same time, when the semi-circular plate approaches the middle frame, the bottom of the semi-circular plate contacts the surface of the central platform, so that the bottoms of the semi-circular plate and the middle frame are on the same plane, facilitating the precise alignment between the two circular holes on the semi-circular plate and the middle frame for subsequent assembly and fixation.

[0022] 4. By opening the electric slider to drive the conveying roller to rotate, when the conveying roller rotates, the conveyor belt rotates. When the conveyor belt rotates, multiple groups of fixing blocks above it move and change positions, so as to convey and feed the semi-circular plates placed on multiple groups of fixing blocks. By placing the front plate, telescopic rod, and U-shaped part in the docking unit between the semi-circular plate and the conveyor belt, it is convenient to remove the conveyed semi-circular plates.

[0023] 5. The present invention enables the push plate to move up and down in the moving block when the rotating plate rotates. When the push plate moves up and down, it drives the moving block to slide in the moving groove. At this time, the screw passes through the circular holes on the semi-arc plate and the middle frame. Then, the second telescopic rod is opened to push the first telescopic plate downward to retract the nut in the discharge port so that the nut is close to the circular hole in the middle frame. Then, the electric slider is opened to move the screw on the nut. When the rotating plate rotates, the push plate moves upward in the moving block. At this time, the middle frame and the semi-arc plate are fixed, so that the placement column and the screw are separated, thereby completing the assembly operation of the shielding ring.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The invention discloses an assembly device of a shielding ring assembly, which is used for assembling electronic components and belongs to a type of intelligent industrial equipment robot. The assembly shielding ring in the invention is a type of electronic component.

[0040] like Figure 1-Figure 11 As shown, the shielding ring assembly includes an annular tube 1, a middle frame 10 fixedly mounted on the annular tube 1, and a semi-arc plate 11 arranged at the front side of the middle frame 10, screws 12 are arranged between the semi-arc plate 11 and the middle frame 10, and nuts 13 for tightening the screws 12 between the semi-arc plate 11 and the middle frame 10 are arranged at the rear side of the middle frame 10, and the assembly device includes a workbench 2;

[0041] A turntable 3 is installed in the middle of the upper end surface of the workbench 2 for rotation by a motor, a fixing unit 4 for fixing the annular tube 1 is circumferentially arranged on the outer edge of the turntable 3, a docking unit 5 is arranged in the middle of the fixing unit 4, a conveying unit 6 located outside the fixing unit 4 on one side is fixedly installed on the upper end of the workbench 2, and a fastening unit 7 fixedly connected to the workbench 2 is arranged at the rear of the conveying unit 6.

[0042] When the semi-arc plate 11 and the middle frame 10 fit together in the middle to form a circular ring, the screw 12 passes through the circular hole between the semi-arc plate 11 and the middle frame 10, and finally the nut 13 is located on the side of the middle frame 10 away from the semi-arc plate 11 to tighten the nut 13. At this time, the entire shielding ring is assembled.

[0043] The fixing unit 4 comprises a circular plate 40, a semicircular groove is provided on one side of the lower end surface of the circular plate 40, and the semicircular groove is fixedly connected to the turntable 3; a plurality of through grooves 41 are provided in an annular direction on the upper end surface of the circular plate 40, and a work-shaped frame 42 is slidably installed in the through groove 41; an arc-shaped support 43 is fixedly installed on the upper end surface of the work-shaped frame 42, and an electric slide is provided in the middle part of the inner wall of the arc-shaped support 43; a threaded rotating rod 44 is threadedly rotatably installed in the middle part of the lower end surface of the circular plate 40, and a threaded ring is threadedly rotatably provided on the threaded rotating rod 44, and a lifting ring 45 slidably connected to the threaded ring is sleeved on the outside of the threaded ring, and a plurality of pull plates 46 arranged in an annular direction are hinged on the outer side of the lifting ring 45, and the pull plate 46 is hinged to the lower end surface of the work-shaped frame 42 on the side away from the lifting ring 45.

[0044] A slide groove 47 is circumferentially provided on the upper end surface of the circular plate 40, and the slide grooves 47 are staggered between the through grooves 41. An L-shaped plate 48 is slidably installed in the slide groove 47, and a spring connected to the slide groove 47 is fixedly installed on one side of the L-shaped plate 48. A fixing piece 49 is fixedly installed on the upper end surface of the L-shaped plate 48, and a hook plate 490 is rotatably installed in the middle of the fixing piece 49.

[0045] The arrangement of the arc-shaped support 43 facilitates the placement of the annular tube 1 in the shielding ring assembly, and the opening of the electric slide can drive the annular tube 1 to rotate and adjust on the arc-shaped support 43, so that the middle frame 10 and the semi-arc plate 11 can be quickly docked. When the arc-shaped support 43 supports the annular tubes 1 of different diameters, the threaded rotating rod 44 is rotated. When the threaded rotating rod 44 rotates, the threaded ring on the upper part thereof is driven to rotate. When the threaded ring rotates, the lifting ring 45 outside thereof is lifted and lowered. When the lifting ring 45 is lifted and lowered, the pull plate 46 is used to push and pull the work frame 42, so that the arc-shaped supports 43 above the multiple work frames 42 are moved closer to or farther away from each other, thereby achieving the placement of the annular tubes 1 of different diameters, and then completing the subsequent docking.

[0046] The hook plate 490 is rotated to hook onto the outer wall of the annular tube 1, and at the same time, the L-shaped plate 48 slides in the slide groove 47 in a direction away from the annular tube 1 under the action of the spring. At this time, the annular tube 1 is fixed under the action of multiple hook plates 490 to prevent the annular tube 1 placed on the arc support 43 from sliding and deviating when the multi-station circular plate 40 rotates, thereby affecting subsequent assembly operations.

[0047] The docking unit 5 includes a central platform 51 arranged in the middle of the circular plate 40. In the middle of the rear side of the central platform 51, a rear slot 52 is opened. On both sides of the rear slot 52, support plates 53 are fixedly installed. A gear 54 is rotatably installed between the two support plates 53 on both sides through a motor. A toothed plate 55 is engaged below the gear 54. The toothed plate 55 is slidably connected to the middle part of the lower end surface of the central platform 51. A front slot 56 is opened in the middle of the front side of the central platform 51. A front plate 57 is fixedly installed on the front side of the toothed plate 55. A telescopic rod 58 is fixedly installed on the upper end surface of the front plate 57. The telescopic rod 58 slides in the front slot 56. The telescopic end of the telescopic rod 58 is fixedly installed with a C-shaped part 59.

[0048] The setting of the central platform 51 facilitates the placement of the lower part of the middle frame 10. At the same time, when the semi-circular plate 11 approaches the middle frame 10, the bottom of the semi-circular plate 11 contacts the surface of the central platform 51, so that the bottoms of the semi-circular plate 11 and the middle frame 10 are on the same plane, which is convenient for the precise alignment between the two circular holes on the semi-circular plate 11 and the middle frame 10, so as to facilitate subsequent assembly and fixation.

[0049] When the conveying unit 6 conveys the semi-circular plate 11 close to the central platform 51, at this time, the motor is turned on to drive the gear 54 to rotate clockwise. When the gear 54 rotates, it drives the toothed plate 55 to move. At this time, the front plate 57 on the front side of the toothed plate 55 moves towards the semi-circular plate 11 until the front plate 57 is placed below the semi-circular plate 11. At this time, the telescopic rod 58 is turned on to extend upward so that the C-shaped part 59 holds and restricts the lower part of the semi-circular plate 11. Then the motor is turned on to make the gear 54 rotate counterclockwise. At this time, the C-shaped part 59 drives the semi-circular plate 11 to disengage from the stabilizing rod 69. When the semi-circular plate 11 disengages from the stabilizing rod 69, the pushing baffle 692 is pushed to flip along the horizontal axis 691. When the telescopic rod 58 enters the front slot 56, the electric push rod retracts to make the C-shaped part 59 drive the semi-circular plate 11 to move downward. At this time, the bottom of the semi-circular plate 11 contacts the surface of the central platform 51. Then, with the continuous movement of the toothed plate 55, the semi-circular plate 11 contacts the middle frame 10. At this time, the two circular holes on the semi-circular plate 11 and the two circular holes on the middle frame 10 are on the same axis, which is convenient for the subsequent insertion of the screw 12.

[0050] The conveying unit 6 includes a conveying frame 61. On both sides of the middle part of the lower end surface of the conveying frame 61, hydraulic rods 62 are correspondingly installed. The ends of the hydraulic rods 62 far from the conveying frame 61 are fixedly connected to the workbench 2. A plurality of conveying rollers 63 are rotatably installed in the middle of the conveying frame 61 through electric sliders. A conveyor belt 64 is commonly arranged outside the conveying rollers 63. A plurality of groups of symmetrically arranged fixing blocks 65 are arranged on the conveyor belt 64.

[0051] A rear plate 66 is fixedly installed at the rear of the fixed block 65. A T-shaped groove 67 is vertically formed on one side of the rear plate 66 close to the fixed block 65. A T-shaped block 68 is slidably installed in the T-shaped groove 67. A spring placed in the T-shaped groove 67 is fixedly installed on the lower end surface of the T-shaped block 68. A stabilizing rod 69 is fixedly installed on the front side of the T-shaped block 68.

[0052] Since a spring is placed in the T-shaped groove 67, when the semi-circular plate 11 moves out of the stabilizing rod 69, at this time, the stabilizing rod 69顶升s upward under the action of the spring, and then the T-shaped blocks 68 on both sides drive the stabilizing rod 69 to move upward, so as to facilitate placing the semi-circular plate 11 on the two stabilizing rods 69 subsequently.

[0053] A front frame 690 is fixedly installed on one side of the fixed block 65 away from the rear plate 66. A horizontal shaft 691 is horizontally fixedly installed in the middle of the front frame 690. A baffle 692 is rotatably installed outside the horizontal shaft 691. A spring is jointly installed between the baffle 692 and the front frame 690.

[0054] Through the setting of the baffle 692, under the action of the spring, the baffle 692 flips to resist the placed semi-circular plate 11, avoiding the semi-circular plate 11 moving out of the stabilizing rod 69 during transportation. At the same time, when the U-shaped member 59 pulls the semi-circular plate 11 to make it脱离 the stabilizing rod 69, the semi-circular plate 11 pushes the baffle 692 to make it flip along the horizontal shaft 691. Through the setting of the baffle 692, on the one hand, it avoids the semi-circular plate 11脱离 the stabilizing rod 69 during transportation, and on the other hand, it does not affect the semi-circular plate 11 moving out of the stabilizing rod 69 after being pulled by the U-shaped member 59.

[0055] When transporting the semi-circular plate 11, the electric slider is turned on to drive the conveying roller 63 to rotate. When the conveying roller 63 rotates, the conveyor belt 64 rotates. When the conveyor belt 64 rotates, multiple groups of fixed blocks 65 above it move and change positions, so that the semi-circular plates 11 placed on the multiple groups of fixed blocks 65 are conveyed and fed. Through the front plate 57, the telescopic rod 58, and the U-shaped member 59 in the docking unit 5 being placed between the semi-circular plate 11 and the conveyor belt 64, it is convenient to remove the conveyed semi-circular plate 11.

[0056] The fastening unit 7 includes a support frame 71. A moving groove 72 is horizontally formed in the upper part of the support frame 71. A moving block 73 is slidably installed in the moving groove 72. A rotating plate 74 rotatably connected to the support frame 71 is provided at the rear of the moving groove 72. The rotating plate 74 is rotatably connected to the support frame 71 through an electric slider. A pushing plate 75 is hinged to one side of the rotating plate 74 away from the support frame 71. The pushing plate 75 passes through and slides in the moving block 73. A cross plate 76 is fixedly installed at one end of the pushing plate 75 away from the rotating plate 74.

[0057] The first telescopic plate 761 is installed on both sides of the upper end surface of the horizontal plate 76, and the second telescopic plate 762 is fixedly installed on the telescopic end of the first telescopic plate 761. The second telescopic plate 762 is provided with a placement plate 763 on the side close to the horizontal plate 76. The middle part of the placement plate 763 is a hollow groove for placing the nut 13. The placement plate 763 passes through and slides in the first telescopic plate 761. A discharge port 764 is provided on the side close to the placement plate 763. The second telescopic plate 762 is fixedly installed with a cylinder 765 on the side away from the placement plate 763. The telescopic end of the cylinder 765 passes through the second telescopic plate 762, and a circular hole is provided in the middle part of the lower side of the second telescopic plate 762.

[0058] A placement column 77 is installed in the middle of both sides of the horizontal plate 76 through an electric slider. A magnetic suction port 78 is opened on the front side of the placement column 77. The side wall of the magnetic suction port 78 is used to magnetically attract the screw 12. The magnetic suction port 78 is a hexagonal setting to adapt to the screw 12.

[0059] When the locking cam 75 is in the unlocking state, the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state, so that the locking cam 73 is locked and the locking cam 73 is locked.

[0060] When the present invention is in use, the arrangement of the arc-shaped support 43 facilitates the placement of the annular tube 1 in the shielding ring assembly, and the opening of the electric slide can drive the annular tube 1 to rotate and adjust on the arc-shaped support 43, so that the middle frame 10 and the semi-arc plate 11 can be quickly docked. When the arc-shaped support 43 supports the annular tubes 1 of different diameters, the threaded rotating rod 44 is rotated, and the threaded rotating rod 44 drives the threaded ring on the upper part to rotate when the threaded rotating rod 44 rotates. When the threaded ring rotates, the lifting ring 45 outside the threaded ring performs a lifting operation. When the lifting ring 45 is lifted and lowered, the pull plate 46 pushes and pulls the I-shaped frame 42, so that the arc-shaped supports 43 above the multiple I-shaped frames 42 are moved closer to or away from each other, thereby achieving the placement of annular tubes 1 of different diameters, and then completing the subsequent docking.

[0061] By rotating the hook plate 490 to hook the outer wall of the annular pipe 1, and at the same time, under the action of the spring, the L-shaped plate 48 slides away from the annular pipe 1 in the chute 47. At this time, under the action of multiple hook plates 490, the annular pipe 1 is fixed, preventing the annular pipe 1 placed on the arc-shaped support 43 from sliding and shifting when the circular plate 40 rotates at multiple workstations, thus affecting the subsequent assembly operation;

[0062] The setting of the central platform 51 facilitates the placement of the lower part of the middle frame 10. At the same time, when the semi-circular arc plate 11 approaches the middle frame 10, the bottom of the semi-circular arc plate 11 contacts the surface of the central platform 51, so that the bottoms of the semi-circular arc plate 11 and the middle frame 10 are on the same plane, facilitating the precise alignment between the two round holes on the semi-circular arc plate 11 and the middle frame 10 for subsequent assembly and fixation;

[0063] When the conveying unit 6 conveys the semi-circular arc plate 11 close to the central platform 51, the motor is started at this time to drive the gear 54 to rotate clockwise. When the gear 54 rotates, it drives the toothed plate 55 to move. At this time, the front plate 57 on the front side of the toothed plate 55 moves towards the semi-circular arc plate 11 until the front plate 57 is placed under the semi-circular arc plate 11. At this time, the telescopic rod 58 is started to extend upward to make the C-shaped part 59 support and hold the lower part of the semi-circular arc plate 11. Then the motor is started to make the gear 54 rotate counterclockwise. At this time, the C-shaped part 59 drives the semi-circular arc plate 11 to disengage from the stabilizing rod 69. When the semi-circular arc plate 11 disengages from the stabilizing rod 69, the pushing baffle 692 is pushed to flip along the horizontal axis 691. The telescopic rod 58 enters the front position groove 56, and the electric push rod retracts to make the C-shaped part 59 drive the semi-circular arc plate 11 to move downward. At this time, the bottom of the semi-circular arc plate 11 contacts the surface of the central platform 51. Then, with the continuous movement of the toothed plate 55, the semi-circular arc plate 11 contacts the middle frame 10. At this time, the two round holes on the semi-circular arc plate 11 and the two round holes on the middle frame 10 are on the same axis, facilitating the subsequent insertion of the screw 12;

[0064] The T-shaped groove 67 is internally provided with a spring. When the semi-circular arc plate 11 moves out of the stabilizing rod 69, the stabilizing rod 69顶升under the action of the spring, so that the two T-shaped blocks 68 on both sides drive the stabilizing rod 69 to move upward, facilitating the subsequent placement of the semi-circular arc plate 11 on the two stabilizing rods 69. Through the setting of the baffle 692, under the action of the spring, the baffle 692 flips to resist the placed semi-circular arc plate 11, preventing the semi-circular arc plate 11 from moving out of the stabilizing rod 69 during the conveying process. At the same time, when the C-shaped part 59 pulls the semi-circular arc plate 11 to make it disengage from the stabilizing rod 69, the semi-circular arc plate 11 pushes the baffle 692 to make it flip along the horizontal axis 691. Through the setting of the baffle 692, on the one hand, it prevents the semi-circular arc plate 11 from disengaging from the stabilizing rod 69 during conveying, and on the other hand, it does not affect the semi-circular arc plate 11 from moving out of the stabilizing rod 69 after being pulled by the C-shaped part 59;

[0065] When the semi-arc plate 11 is transported, the electric slider is opened to drive the conveying roller 63 to rotate, and when the conveying roller 63 rotates, the conveying belt 64 rotates, and when the conveying belt 64 rotates, the multiple groups of fixed blocks 65 above it move and change positions, so that the semi-arc plate 11 placed on the multiple groups of fixed blocks 65 is transported and fed, and the front plate 57, the telescopic rod 58, and the shaped member 59 in the docking unit 5 are placed between the semi-arc plate 11 and the conveying belt 64, so as to facilitate the removal of the transported semi-arc plate 11;

[0066] After the semi-arc plate 11 and the middle frame 10 are docked, the motor is turned on to make the turntable 3 continue to rotate (the turntable 3 rotates at an angle of 60 degrees each time). At this time, the circular plate 40 rotates to the bottom of the fastening unit 7, and then the electric slider is turned on to drive the turntable 74 to rotate. When the turntable 74 rotates, the push plate 75 moves up and down in the moving block 73. When the push plate 75 moves up and down, it drives the moving block 73 to slide in the moving groove 72. At this time, the screw 12 passes through the circular holes on the semi-arc plate 11 and the middle frame 10, and then the second extension is turned on. The retracting plate 762 pushes the first telescopic plate 761 downward to retract the nut 13 in the discharge port 764 so that the nut 13 is close to the circular hole of the middle frame 10. Then the electric slider is opened to move the screw 12 on the nut 13. When the rotating plate 74 rotates, the pushing plate 75 moves upward in the moving block 73. At this time, the middle frame 10 and the semi-arc plate 11 are fixed, so that the placement column 77 is disengaged from the screw 12, thereby completing the assembly operation of the shielding ring. Repeating the above operation facilitates the continuous assembly of the shielding ring.
