Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meter assembly, in particular to a lead seal installation device for electric energy meter assembly. Background Art

[0002] During the assembly process of the electricity meter, in order to prevent non-professionals from making unauthorized changes or adjustments to the electricity meter, the electricity meter needs to be sealed and installed. Once the electricity meter is sealed, no one except those with professional sealing pliers can open it at will. This provides a solid barrier to the measurement accuracy of the electricity meter.

[0003] The Chinese patent with the announcement number CN116275974B discloses an electric energy meter lead seal installation device, which relates to the field of electric energy meter assembly technology, including an operating table, on the top surface of which an electric energy meter conveyor belt and a lead seal bean correction clamping device are arranged in parallel, and a plurality of electric energy meter placement seats are arranged in parallel along the length direction on the electric energy meter conveyor belt. The electric energy meter placement seat includes a seat groove fixedly arranged on the electric energy meter conveyor belt, the top of the seat groove is open, and the seat groove is provided with adjustment clamps on the two opposite side walls, and a movable discharge component is provided on the other side wall of the seat groove. The clamping device includes a sealing bean conveying trough and a discharge trough which are arranged in parallel on the top surface of the operating table along the length direction of the electric energy meter conveyor belt. A position correction component is provided in the sealing bean conveying trough, and a sealing machine is provided between the sealing bean conveying trough and the discharge trough. Although the above patent can flatten the sealing beans to complete the sealing of the electric energy meter, the sealing beans and the copper wire are prone to swinging and displacement during the process of moving the electric energy meter to the pressing position due to the light material of the sealing beans and the copper wire, resulting in the inability to accurately move to the bottom of the pressing position, resulting in insufficient pressing of the seal, affecting the sealing effect.

[0004] The present invention aims to solve the problems existing in the above patents. To this end, a lead seal installation device for electric energy meter assembly is proposed, which can center the lead seal bean and the copper wire to ensure accurate positioning and sufficient pressing, thereby improving the lead sealing effect. Summary of the Invention

The wedge block is located above the porous hollow disk, and a reset spring is symmetrically connected between the wedge block and the annular plate.

[0010] Further description, it also includes a switching component, which includes an L-shaped plate fixed to the top of the base, the L-shaped plate is located above the electric transverse movement seat, and the L-shaped plate is rotatably connected to the electric rotating disk, and the electric rotating disk is rotatably connected with four groups of arc-shaped clamps at evenly spaced intervals along the circumference.

Then move the energy meter, the fixed copper wire and the lead sealing bean to the pressing area for pressing to complete the lead sealing process. In this way, by fixing the lead sealing bean and the copper wire, the accuracy of the position of the lead sealing bean and the copper wire and the sufficient pressing can be ensured, thereby improving the lead sealing effect.

Under the action of the pressure release component, whenever the seal bean is pressed and fixed on the copper wire, the pressure component can make the porous hollow disk drive the seal bean to move downward, so that the seal bean and the pressure block move downward synchronously and stop being pressed. This can prevent the pressure of the pressure block from exceeding the force that the seal bean can withstand, causing the seal bean to be crushed, thereby ensuring the safety of the seal bean.

The return springs 101 are symmetrically connected between the outer side of the wedge block 10 and the inner side of the annular plate 8.

[0035] See also Figure 6-Figure 9As shown, it also includes a switching component installed on the base 1, the switching component includes an L-shaped plate 16, an electric rotating disk 161, an arc-shaped clamping plate 162, a tension spring I 1621, a locking component, a limit frame 166 and a cylinder 167. The front side of the top of the base 1 is fixed with an L-shaped plate 16, the L-shaped plate 16 is located above the electric transverse movement seat 2, and the rear side of the L-shaped plate 16 is rotatably connected to the electric rotating disk 161. Four groups of arc-shaped clamping plates 162 are rotatably connected to the electric rotating disk 161 at uniform intervals along the circumferential direction. The number of each group of arc-shaped clamping plates 162 is two, and the arc-shaped clamping plates 162 can clamp and fix different styles of pressure blocks 6. The side of each group of two arc-shaped clamping plates 162 away from each other is an inclined surface, and the side of each group of two arc-shaped clamping plates 162 close to each other is connected with a tension spring I 1621. The electric rotating disk 161 is circumferentially evenly spaced. There are four limit frames 166 slidingly connected at even intervals, and the limit frames 166 are in contact with the inclined surface of the arc-shaped splint 162. The limit frames 166 can limit the arc-shaped splint 162. Four cylinders 167 are fixedly connected to the top of the electric rotating disk 161 at even intervals along the circumferential direction. The ends of the telescopic rods of the four cylinders 167 are respectively fixedly connected to the upper parts of the four limit frames 166. A locking assembly is provided between the pressure block 6 and the electric column 5, and the locking assembly can lock the pressure block 6; the locking assembly includes an iron block 163, a tension spring II 164 and an electromagnet 165. The top of the pressure block 6 is embedded with the iron block 163 in a sliding connection, and a tension spring II 164 is connected between the bottom of the iron block 163 and the inner side of the pressure block 6. The electromagnet 165 is embedded and fixedly connected to the inner side of the lower part of the electric column 5, and the electromagnet 165 is in contact with the iron block 163.

[0036] Initially, the conduit 14 is connected to an external vacuum pump, and the tension spring I 1621 is in a compressed state. Three sets of arc-shaped clamping plates 162 are respectively clamped with three different styles of pressure blocks 6. First, the electromagnet 165 is started. The electromagnet 165 sucks the iron block 163 upward and fixes it by magnetic force. The tension spring II 164 is stretched, and then the electric energy meter with the copper wire is placed in the right placement slot 3. The electric energy meter contacts the right clamping plate 7, and the electric energy meter drives the right clamping plate 7 to move outward. The right connecting spring 71 is compressed. After the electric energy meter is placed, the right clamping plate 7 can clamp the electric energy meter. Then, the lead seal bean on the copper wire is placed in the annular plate 8. The lead seal bean contacts the inclined surface of the right wedge block 10. The placement of the lead seal bean drives the right wedge block 10 to move outward, and the reset spring 1 01 is compressed. When the lead seal bean moves downward and contacts the porous hollow disk 13, the lead seal bean is placed. The right wedge block 10 corrects the position of the lead seal bean so that the lead seal bean is in the center position of the porous hollow disk 13. Then the copper wire passes through the front and rear grooves 9 and is in the elastic holder 12. The elastic holder 12 limits the copper wire. Then the external vacuum pump is started. The external vacuum pump exhausts air in the porous hollow disk 13 through the conduit 14, so that the porous hollow disk 13 is in a negative pressure state. The porous hollow disk 13 absorbs and fixes the lead seal bean. Then the electric transverse seat 2 is started to move to the left. The electric transverse seat 2 drives the electric energy meter to move to the left through the clamping plate 7. At the same time, the electric transverse seat 2 also drives the annular plate 8 to move to the left, and the annular plate 8 drives the fixed The cylinder 11 moves to the left, and the fixed cylinder 11 drives the porous hollow disk 13 to move to the left through the guide tube 14. The porous hollow disk 13 drives the sucked lead sealing beans to move to the left, and the lead sealing beans drive the copper wire to move to the left. The copper wire and the electric energy meter move to the left synchronously. Since the lead sealing beans and the copper wire are in a fixed state during the movement, the lead sealing beans and the copper wire can be prevented from swinging and displacing, thereby ensuring the stability of the lead sealing beans and the copper wire during the movement. When the lead sealing beans move to the left to just below the pressing block 6, the electric transverse seat 2 is closed, and the electric energy meter, lead sealing beans and copper wire stop moving to the left. At this time, the operator can place the next electric energy meter into the left placement slot 3 according to the above operation, and fix the copper wire and the lead sealing beans. At this time, the rear cylinder 167 is started, and the telescopic rod of the rear cylinder 167 is retracted. The short drive rear limit frame 166 moves forward, and the rear limit frame 166 moves forward and disengages from the rear arc-shaped clamping plate 162. Due to the action of the rear extension spring Ⅰ1621, the two rear arc-shaped clamping plates 162 swing outward and disengage from the pressure block 6 on the electric column 5. The rear cylinder 167 is closed, and the electric column 5 can be started. The electric column 5 moves downward and drives the rear pressure block 6 to move downward. The rear pressure block 6 moves downward and contacts the wedge block 10 first. The rear pressure block 6 drives the wedge block 10 to move outward, and the return spring 101 is compressed. The wedge block 10 moves outward and disengages from the seal bean. Then the rear pressure block 6 continues to move downward and contacts the seal bean directly below. The rear pressure block 6 presses the seal bean directly below, so that the seal bean is fixed to the copper wire.The sealing process of the electric energy meter is completed, and then the electric column 5 is started to drive the rear side pressure block 6 to move upward and reset. The rear side pressure block 6 is reset and disengaged from the sealing bean. The rear side pressure block 6 is reset and disengaged from the wedge block 10. Due to the action of the reset spring 101, the wedge block 10 moves inward and contacts the sealing bean. Then the electric transverse seat 2 is started to move to the right, so that the sealed electric energy meter moves to the right to the maximum stroke. At the same time, the electric transverse seat 2 drives the unsealed electric energy meter to move to the right to the sealing area. According to the above operation, the electric column 5 is continued to be started to make the rear side pressure block 6 move downward to press the sealing bean. At the same time, the operator can turn off the vacuum pump, the porous hollow disk 13 stops pumping air, and the pressed sealing bean stops being sucked and fixed. , the copper wire can be pulled upward to disengage from the elastic holder 12. The upward movement of the copper wire drives the pressed lead seal bean to move upward to disengage from the right wedge block 10. Due to the action of the reset spring 101, the right wedge block 10 moves inward to reset, and then the electric energy meter is taken out from the right placement slot 3. The electric energy meter is disengaged from the right clamping plate 7. Due to the action of the right connecting spring 71, the right clamping plate 7 moves inward to reset, and the next electric energy meter, lead seal bean and copper wire can be placed and fixed. When the left electric energy meter completes the lead sealing process, the electric transverse seat 2 is started to move to the maximum stroke to the left, so that the sealed electric energy meter moves to the left and out of the lead sealing area. This process is repeated, and the electric energy meter can be continuously sealed. In this way, by fixing the lead seal bean and the copper wire, the accuracy of the position of the lead seal bean and the copper wire and sufficient pressing can be guaranteed, thereby improving the lead sealing effect;

[0037] When it is necessary to adjust the style of pressing the lead seal bean, the electromagnet 165 is turned off, and the electromagnet 165 stops sucking the iron block 163. Due to the action of the tension spring II 164, the iron block 163 moves downward and is retracted into the pressure block 6, which does not affect the switching of the pressure block 6. Then the rear cylinder 167 is started, and the telescopic rod of the rear cylinder 167 is extended to drive the rear limit frame 166 to move backward. The rear limit frame 166 moves backward and pushes the two rear arc splints 162 to swing inward and reset through the inclined surface. The rear tension spring I 1621 is compressed, and the two rear arc splints 162 are reset to clamp the rear pressure block 6. Then the electric rotary disk 161 is started to rotate. The rotation of the electric rotary disk 161 drives the arc splint 162 to rotate, and the rotation of the arc splint 162 drives the pressure block 6 rotates, and the rear pressure block 6 rotates and disengages from the electric column 5. When the pressure block 6 of the required style rotates onto the electric column 5, the electric rotating disk 161 is closed, the arc-shaped clamping plate 162 stops driving the pressure block 6 to rotate, and the electromagnet 165 is started. The electromagnet 165 attracts the rear iron block 163 to move upward, and the rear tension spring II 164 is stretched. The rear iron block 163 moves upward and is magnetically contacted by the electromagnet 165 and is fixed. The electromagnet 165 cooperates with the iron block 163 to lock the rear pressure block 6. Then the rear cylinder 167 is started to drive the rear limit frame 166 to move forward to the maximum stroke. The rear limit frame 166 disengages from the rear arc-shaped clamping plate 162. Due to the action of the rear tension spring II 164, the rear arc-shaped clamping plate 162 releases the rear pressure block 6. In this way, the style of pressing the lead-sealed beans can be switched according to needs, thereby meeting different needs and improving adaptability.

[0038] See also Figure 10 and Figure 11As shown, the lead seal installation device for assembling the electric energy meter also includes a pressure relief assembly installed between the porous hollow disk 13 and the fixed cylinder 11, the pressure relief assembly includes an electric push rod 17, a ring 171, a pressure sensor 172, a fixed ratchet plate 173 and a limit assembly. The pressure sensor 172 is embedded in the middle of the top of the porous hollow disk 13 and fixedly connected. The pressure sensor 172 can detect the force of pressing. Four fixed ratchet plates 173 are fixedly connected at regular intervals along the circumferential direction at the bottom of the porous hollow disk 13. The electric push rod 17 is fixedly connected to the front and rear symmetrical ends of the outer side of the fixed cylinder 11. A ring 171 is fixedly connected between the ends of the telescopic rods of the electric push rods 17 on the front and rear sides. A limit assembly is arranged between the ring 171 and the fixed cylinder 11. When the limit assembly is in operation, the limit assembly can limit the fixed ratchet plate 173. To limit the porous hollow disk 13; the limiting assembly includes a driving frame 174, a movable ratchet plate 175 and a straight hole plate 176. The lower inner part of the fixed cylinder 11 is slidably connected with four movable ratchet plates 175 at evenly spaced intervals along the circumferential direction. The movable ratchet plate 175 engages with the fixed ratchet plate 173. The movable ratchet plate 175 can limit the fixed ratchet plate 173. The four movable ratchet plates 175 are evenly spaced and fixed with four straight hole plates 176 on one side away from each other. The straight hole plates 176 are tilted. Four driving frames 174 are evenly spaced and fixed to the top of the ring 171. The driving frame 174 slides through the bottom of the fixed cylinder 11. The driving frame 174 is slidably connected to the straight hole plate 176. When the driving frame 174 moves, the driving frame 174 can drive the straight hole plate 176 to move in and out.

[0039] When the sealing bean is sucked onto the porous hollow disk 13, the sealing bean contacts the pressure sensor 172, and then when the pressing block 6 presses the sealing bean, the pressure sensor 172 detects the pressing force. When the force detected by the pressure sensor 172 reaches the set value, the sealing bean has completed the pressing. The pressure sensor 172 controls the electric push rod 17 to start through the control module. The telescopic rod of the electric push rod 17 extends to drive the ring 171 to move downward. The ring 171 moves downward to drive the driving frame 174 to move downward. The driving frame 174 moves downward to drive the slotted hole plate 176 to move outward. The slotted hole plate 176 moves outward to drive the movable ratchet plate 175 to move outward. The movable ratchet plate 175 moves outward and disengages from the fixed ratchet plate 173. The fixed ratchet plate 173 stops being limited. The pressing of the pressing block 6 drives the porous hollow disk 13 to move downward through the sealing bean, and the buffer spring The spring 15 is compressed, and the porous hollow disk 13 moves downward, driving the fixed ratchet plate 173 to move downward. At this time, the lead seal bean and the pressure block 6 move synchronously. The lead seal bean is not subjected to the pressure of the pressure block 6 at this time. Subsequently, when the pressure block 6 moves upward and resets, the pressure block 6 is out of contact with the lead seal bean. Due to the action of the buffer spring 15, the porous hollow disk 13 moves upward and resets, driving the fixed ratchet plate 173 and the lead seal bean to move upward and reset. Then the electric push rod 17 is started to drive the ring 171 to move upward and reset. The ring 171 moves upward and resets, driving the driving frame 174 to move upward and reset. The driving frame 174 resets and drives the straight hole plate 176 to move inward and reset. The straight hole plate 176 drives the movable ratchet plate 175 to move inward and reset. The movable ratchet plate 175 moves inward and resets and engages with the fixed ratchet plate 173. The movable ratchet plate 175 cooperates with the fixed ratchet plate 173 to limit the porous hollow disk 13. In this way, the pressure applied by the pressing block 6 can be prevented from exceeding the pressure that the sealing beans can withstand, causing the sealing beans to be crushed, thereby ensuring the safety of the sealing beans.

[0040] See also Figure 1 As shown, the lead seal installation device for assembling an electric energy meter further includes a placement frame 18 , and the placement frame 18 is fixedly connected to the front side of the base 1 , and the placement frame 18 can be used to place the lead seal beans and copper wire to be used.

[0041] When the electric energy meter is being sealed, the operator can put the copper wire and the sealing beans to be installed into the placement frame 18. When needed, the copper wire and the sealing beans can be taken out from the placement frame 18. In this way, it is more convenient to use the copper wire and the sealing beans.
