Description

Technical Field

[0001] This invention relates to the field of electricity meter assembly technology, and more specifically, to an electricity meter lead seal installation device and its installation method. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy; it is also called a kilowatt-hour meter, watt-hour meter, or simply an electric meter. In the electricity meter assembly industry, lead seals are an important security feature. Therefore, electricity meters need to be sealed with lead seals when they leave the factory. Depending on the requirements, some electricity meters require three lead seals, while others require two. These lead seals are installed in the corresponding holes in the electricity meter.

[0003] In existing technology, when installing lead seals on electricity meters, multiple workstations are typically set up. Multiple lead-sealing machines sequentially seal the holes on the electricity meter. During lead sealing, a vacuum suction cup is used to pick up the lead seal and press it onto the meter. However, during the lead seal feeding process, the lead seal may tilt slightly as it moves through the feeding channel. This can easily cause the lead seal to be misaligned or off-center when using the vacuum suction cup. If the positional deviation between the lead seal and the vacuum suction cup is too large, the contact between the lead seal and the electricity meter will also be off, causing damage to the meter cover. Furthermore, during lead sealing, excessive pressure at the lead seal holes can cause deformation or breakage of the meter cover at the holes. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an electricity meter lead seal installation device to solve the following technical problem: the contact position of the electricity meter lead seal is also deviated, which causes damage to the electricity meter cover.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An electricity meter lead seal installation device includes a conveying mechanism, a lead seal feeding mechanism, and a lead seal installation mechanism;

[0007] The conveying mechanism is used for conveying the electricity meter, and the lead seal feeding mechanism is used for feeding the lead seal. The lead seal feeding mechanism is located on one side of the lead seal installation mechanism.

[0008] The lead seal installation mechanism is mounted on the conveying mechanism. The lead seal installation mechanism includes a support frame, a pressing assembly for lead seal pressing operations, and an energy meter positioning assembly for positioning and diverting energy meters.

[0009] The pressing assembly includes two symmetrically arranged pressing guns, which are mounted on a back plate via a fixed plate. The back plate is slidably mounted on a crossbeam support. A push cylinder is provided on the back plate, and the piston rod of the push cylinder is fixedly connected to the back plate. The fixed plate is slidably mounted on the back plate.

[0010] The pressing gun includes a pressing rod, a pressing tube fixedly connected to the bottom of the pressing rod, a vacuum suction cup connected to the bottom of the pressing tube, a connecting pipe connected to the pressing tube on the pressing rod, a fixing ring fixedly sleeved on the pressing tube, and auxiliary pressing components symmetrically arranged on both sides of the fixing ring. The auxiliary pressing components are used to disperse the pressure when pressing the lead seal onto the energy meter cover. The auxiliary pressing components include a fixing rod, a telescopic rod slidably installed inside the fixing rod, and an elastic element inside the fixing rod. One end of the elastic element is connected to the inner wall of the fixing rod, and the other end is connected to the end of the telescopic rod. A pressing seat is installed at the bottom of the telescopic rod, and a calibration rod is rotatably installed in a calibration groove opened in the pressing seat. A micro motor is also provided on one side of the pressing seat, which drives the calibration rod to rotate in the calibration groove. An infrared ranging sensor is provided on the side of the pressing seat facing the pressing tube, and the infrared ranging sensor is used to measure the distance between the lead seal and the pressing seat.

[0011] As a further embodiment of the present invention, the energy meter positioning component includes a baffle, with positioning brackets symmetrically arranged on both sides of the baffle. The positioning brackets are rotatably mounted on the baffle, and a positioning clamp is provided on one side of each of the two positioning brackets. The positioning clamp is driven by a positioning cylinder, which is mounted on one side of the positioning bracket. A flow guide bracket is provided on one side of each of the two positioning brackets, and a driving cylinder is provided on the support frame. The piston rod of the driving cylinder is connected to the end of the baffle.

[0012] As a further embodiment of the present invention, a diverter plate is rotatably mounted on the flow guide bracket, and the diverter plate limits the power meter on the conveying mechanism.

[0013] As a further embodiment of the present invention, the flow guide bracket is provided with a movable groove, the positioning bracket is slidably installed in the movable groove via a movable rod, the movable rod is rotatably installed at the end of the positioning bracket, and a driven rod is rotatably installed on one side of the flow divider plate, the driven rod being rotatably installed on the movable rod.

[0014] As a further embodiment of the present invention, the height of the vacuum suction cup is higher than the height of the press-fit base.

[0015] As a further embodiment of the present invention, the fixing ring is provided with symmetrical fixing grooves on both sides, and the fixing rod of the auxiliary pressing component is engaged with the fixing groove. By adjusting the position of the auxiliary pressing component on the fixing groove, the rotation angle of the pressing seat can be adjusted to always be in contact with the cover of the electricity meter.

[0016] As a further embodiment of the present invention, a movable lead screw is rotatably mounted on the crossbeam support, a movable motor for driving the movable lead screw to rotate is provided on one side of the crossbeam support, and the back plate is threadedly connected to the movable lead screw on one side.

[0017] As a further embodiment of the present invention, each of the two press guns is equipped with a connecting bracket, and a sliding groove is provided at the top of the fixed plate. Both connecting brackets are slidably installed in the sliding groove and fixed by locking bolts.

[0018] A method for installing a lead seal mounting device for an electricity meter includes the following steps:

[0019] Step 1: Use a mobile motor to move the back plate on the crossbeam support. The pressing gun on the back plate moves to the lead seal feeding mechanism. The pressing gun picks up the lead seal on the lead seal feeding mechanism and moves it to the conveying mechanism. The positioning clamp is used to fix the energy meter.

[0020] Step 2: The pressing gun moves downwards, and the pressing seat on the auxiliary pressing part contacts the meter cover first. The telescopic rod on the pressing seat abuts against the surface of the meter cover under the action of the elastic element, pressing and fixing the lead seal of the meter around it. The infrared distance sensor on the pressing seat measures the distance between the lead seal and the sensor, and the position of the lead seal is determined according to the measured distance.

[0021] Step 3: Based on the positional offset of the lead seal, when the measured distance of the lead seal exceeds the set value, the calibration rods on the two pressing bases rotate synchronously to clamp the lead seal at the bottom of the vacuum suction cup in the center position. Then, the vacuum suction cup adsorbs the lead seal and presses it down to complete the installation of the lead seal.

[0022] Step 4: The drive cylinder moves the baffle upward, which in turn moves the positioning brackets on both sides upward. The positioning end of the positioning bracket moves the drive rod, which in turn rotates the diverter plate, releasing the energy meter to be processed below the press gun. The processed energy meter moves out from the baffle side, the baffle moves down, and the relative movement of the two diverter plates limits and diverts the next energy meter to be processed.

[0023] Compared with existing solutions, the beneficial effects of the present invention are as follows:

[0024] This invention enables multi-point lead seal installation of electricity meters by setting up a conveying mechanism, a lead seal feeding mechanism, and a lead seal installation mechanism, eliminating the need to install the lead seals of electricity meters sequentially through multiple workstations and improving processing efficiency.

[0025] The auxiliary pressing component at the bottom of the pressing gun on the lead seal installation mechanism presses and fixes the lead seal around the electricity meter during the pressing operation. This can disperse the pressure during the pressing of the lead seal and avoid damage to the holes in the electricity meter cover. At the same time, the auxiliary pressing component can detect the position of the lead seal and correct any misaligned lead seals, reducing the damage to the electricity meter cover caused by the lead seal tilting or deviating from the center point.

[0026] The energy meter positioning component on the lead seal installation mechanism is used to position and fix the energy meter, which improves the accuracy and stability of the energy meter lead seal. The diverter plate on the energy meter positioning component, together with the baffle, realizes the limit release of the energy meter to be processed and the release operation of the processed energy meter, thereby realizing the diversion operation of the energy meter and avoiding the disorder of the energy meter processing program caused by multiple independent drive devices, thus improving the processing efficiency.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0036] Example 1

[0037] Reference Figures 1-7 As shown, the present invention is a lead seal installation device for an electricity meter, including a conveying mechanism 1, a lead seal feeding mechanism 2, and a lead seal installation mechanism 3; the lead seal installation mechanism 3 is disposed on the conveying mechanism 1, and the lead seal feeding mechanism 2 is disposed on one side of the lead seal installation mechanism 3.

[0038] The lead seal installation mechanism 3 includes a pressing assembly 10 for pressing the lead seal and an energy meter positioning assembly 20 for positioning and diverting energy meters. The pressing assembly 10 is located on one side of the support frame 30 and the energy meter positioning assembly 20 is located on the other side of the support frame 30.

[0039] The press assembly 10 includes two symmetrically arranged press guns 110. The two press guns 110 are mounted on the back plate 112 by a fixing plate 111. The back plate 112 is slidably mounted on the crossbeam bracket 113.

[0040] A push cylinder is provided on the back plate 112, the piston rod of the push cylinder is fixedly connected to the back plate 112, and the fixed plate 111 is slidably installed on the back plate 112.

[0041] The press-fit gun 110 includes a press-fit rod 116, with a press-fit tube 117 fixedly connected to the bottom of the press-fit rod 116. A vacuum suction cup 118 is connected to the bottom of the press-fit tube 117. A connecting pipe communicating with the press-fit tube 117 is provided on the press-fit rod 116, and the connecting pipe is connected to an air pump via a connecting hose. A fixing ring 119 is fixedly fitted on the press-fit tube 117. Auxiliary press-fit components 120 are symmetrically arranged on both sides of the fixing ring 119. The auxiliary press-fit components 120 are used to disperse the pressure during lead seal press-fitting to prevent damage to the holes in the electricity meter cover. The auxiliary press-fit component 120 includes a fixing rod 121, with a telescopic rod 122 slidably installed inside the fixing rod 121. An elastic element, a spring, is provided inside the fixing rod 121. One end of the elastic element is connected to the inner wall of the fixing rod 121, and the other end is connected to the end of the telescopic rod 122. A press-fit seat 123 is installed at the bottom of the telescopic rod 122. A calibration groove 124 is provided inside the pressing base 123, and a calibration rod 125 is rotatably installed in the calibration groove 124. A micro motor 126 is also provided on one side of the pressing base 123. The micro motor 126 drives the calibration rod 125 to rotate in the calibration groove 124. An infrared distance sensor 127 is provided on the side of the pressing base 123 facing the pressing tube 117. The infrared distance sensor 127 is used to measure the distance between the lead seal and the pressing base 123 to avoid damage to the meter cover caused by the lead seal being out of center or tilted at the vacuum suction cup 118. When the infrared distance sensor 127 measures the distance of the lead seal to exceed the set value, it means that the lead seal is not centered. The two calibration rods 125 on the two pressing bases 123 rotate synchronously to clamp the lead seal in the center position, and the vacuum suction cup 118 then adsorbs and moves the lead seal.

[0042] The height of the vacuum suction cup 118 is higher than the height of the pressing base 123, so that when the lead seal is pressed, the pressing base 123 can press and fix the energy meter first, and at the same time, the distance between the lead seal and the pressing base 123 can be measured.

[0043] The fixing ring 119 has symmetrical fixing grooves 128 on both sides. The fixing rod 121 of the auxiliary pressing component 120 is engaged with the fixing groove 128. By adjusting the position of the auxiliary pressing component 120 on the fixing groove 128, the installation of the lead seal at the hole of the electricity meter in different directions can be adapted.

[0044] A movable screw 114 is rotatably mounted on the crossbeam support 113. A movable motor 115 is provided on one side of the crossbeam support 113 to drive the movable screw 114 to rotate. One side of the back plate 112 is threadedly connected to the movable screw 114. The movable screw 114 drives the back plate 112 to move, which in turn drives the pressing gun 110 on one side of the back plate 112 to move, so that the pressing gun 110 moves to the lead seal feeding mechanism 2 to realize the feeding of the lead seal.

[0045] Both press-fit guns 110 are equipped with connecting brackets. The top of the fixed plate 111 has a sliding groove. Both connecting brackets are slidably installed in the sliding groove and fixed by locking bolts. According to the installation position of the lead seal on the electricity meter, the distance between the two connecting brackets on the fixed plate can be adjusted to simultaneously install the lead seals at different positions on the electricity meter. When the lead seal installation positions on the electricity meter are not on the same straight line, that is, when the electricity meters are different models, the length of the connecting brackets can be adjusted to realize the lead seal installation operation of electricity meters at different lead seal installation positions.

[0046] The electricity meter positioning assembly 20 includes a baffle 200, with positioning brackets 201 symmetrically arranged on both sides of the baffle 200. The positioning brackets 201 are rotatably mounted on the baffle 200. A positioning clamping plate 202 is provided on the opposite side of each of the two positioning brackets 201. The positioning clamping plate 202 is driven by a positioning cylinder 203. The positioning clamping plate 202 realizes the positioning and fixing of the electricity meter during processing. The positioning cylinder 203 is installed on one side of the positioning bracket 201. A flow guide bracket 204 is provided on one side of each of the two positioning brackets 201. The flow guide bracket 204 is fixedly installed on the conveying mechanism 1. The flow guide bracket 204 is inclined towards the direction of electricity meter flow, so that the electricity meter can move along the flow guide bracket 204 to initially limit the electricity meter.

[0047] A drive cylinder 205 is provided on the support frame 30. The piston rod of the drive cylinder 205 is connected to the end of the baffle 200. A flow divider 206 is rotatably mounted on the flow guide bracket 204. A moving groove 208 is provided on the flow guide bracket 204. A positioning bracket 201 is slidably mounted in the moving groove 208 through a moving rod 207. The moving rod 207 is rotatably mounted on the end of the positioning bracket 201. A driven rod 209 is rotatably mounted on one side of the flow divider 206. The driven rod 209 is rotatably mounted on the moving rod 207.

[0048] When the drive cylinder 205 moves the baffle 200 upward, the baffle 200 moves the positioning brackets 201 on both sides upward. The moving rod 207 at the end of the positioning bracket 201 moves the driven rod 209. The driven rod 209 moves the diverting plate 206 on the guide bracket 204. The diverting rod moves closer to the guide bracket 204, thereby releasing the energy meter to be processed. When the baffle 200 moves downward, the energy meter is blocked by the two separating rods, thus limiting the energy meter to be processed. The driven rod 209 drives the diverting plate 206 to rotate, placing the energy meter into the processing area. The processed energy meter moves out from the baffle 200 side, realizing the diversion of the energy meter and the fixation of the energy meter during processing.

[0049] The conveying mechanism 1 is a conveyor belt device used for transporting electricity meters. By placing the electricity meters on the conveying mechanism 1, the electricity meters can be installed between subsequent mechanisms.

[0050] The lead seal feeding mechanism 2 is a ring feeder. The ring feeder is mainly used for feeding small parts such as screws, which is existing technology. In this invention, the lead seal is placed on the feeding conveyor channel of the ring feeder, and the lead seal will be conveyed along the feeding conveyor channel to one side of the conveyor mechanism 1, thereby realizing the automatic feeding of the lead seal.

[0051] The installation method of the lead seal installation device for an electricity meter according to the present invention is as follows:

[0052] Step 1: The moving motor 115 drives the moving screw 114 to rotate. The moving screw 114 drives the back plate 112 to move on the crossbeam support 113. When the pressing gun 110 on the back plate 112 moves to the lead seal feeding mechanism 2, the two pressing guns 110 adsorb the lead seal on the lead seal feeding mechanism 2 and move to the conveying mechanism 1.

[0053] Step 2: When the pressing gun 110 moves downward, the pressing seat 123 on the auxiliary pressing component 120 contacts the meter cover first. The telescopic rod 122 on the pressing seat 123 abuts against the surface of the meter cover under the action of the elastic element, pressing and fixing the lead seal of the meter around it. At this time, the infrared distance sensor 127 on the pressing seat 123 measures the distance between the lead seal and the sensor. Based on the measured distance, it is determined whether the position of the lead seal has shifted. When the infrared distance sensor 127 measures the distance of the lead seal and does not exceed the set value, it means that the center position of the lead seal has not shifted, and the pressing continues to perform the lead seal installation operation.

[0054] When the infrared ranging sensor 127 measures the distance to the lead seal and it exceeds the set value, it means that the lead seal is not centered and the offset is large. Using the calibration rods 125 on the two pressing seats 123, the two calibration rods 125 rotate synchronously to clamp the lead seal in the center position. The vacuum suction cup 118 then adsorbs the lead seal and presses it down to perform the lead seal installation operation.

[0055] Step 3: After the electricity meter is installed, when the drive cylinder 205 moves the baffle 200 upward, the baffle 200 moves the positioning brackets 201 on both sides upward. The moving rod 207 at the end of the positioning bracket 201 moves the driven rod 209. The driven rod 209 drives the diverter plate 206 to rotate, releasing the electricity meter to be processed and placing it under the press gun 110. The processed electricity meter moves out from the side of the baffle 200, the baffle 200 moves downward, and the two diverter plates 206 move relative to each other to limit the next electricity meter to be processed, thus realizing the diversion of electricity meters.

Step 3: Based on the position offset of the lead seal, when the measured distance of the lead seal exceeds the set value, the calibration rods (125) on the two pressing bases (123) rotate synchronously to clamp the lead seal at the bottom of the vacuum chuck (118) in the center position. Then, the vacuum chuck (118) adsorbs the lead seal and presses it down to complete the installation of the lead seal. Step 4: Drive the baffle (200) upward by driving the cylinder (205). The baffle (200) drives the positioning brackets (201) on both sides to move upward. The positioning end of the positioning bracket (201) drives the drive rod to move. The drive rod drives the diverter plate (206) to rotate, releasing the energy meter to be processed to the bottom of the press gun (110). The processed energy meter moves out from the side of the baffle (200). The baffle (200) moves down. The two diverter plates (206) move relative to each other to limit and divert the next energy meter to be processed.
