Description

Technical Field

[0001] The present invention belongs to the technical field of high-voltage relay processing, and in particular relates to a processing device and process for high-voltage relay components. Background Art

[0002] A high-voltage relay is an electrical control component used in high-voltage circuits and has a wide range of applications in fields such as power systems and industrial automation. A high-voltage relay generally consists of an electromagnetic system, a contact system, an arc extinguishing system, etc. When the electromagnetic coil of the relay is energized, a magnetic field is generated, magnetizing the iron core and attracting the armature to move, thereby driving the contacts to close or open to achieve the control of the high-voltage circuit. When powered off, the electromagnetic force disappears, and the armature returns to its initial position under the action of the return spring, and the contacts also return to their original states. In the manufacturing process of high-voltage relay components, such as casting, injection molding, and compression molding processes, if the mating clearance of the mold is large, it will cause the material to overflow during the forming process, thereby forming burrs at the edge of the inner hole of the component. If the material of the processed component has ductility, toughness, and plasticity, during machining, when the tool cuts the material, the material will undergo uneven deformation, which acts as a resistance to cutting, causing some materials to be torn or extruded, and thus generating burrs.

[0003] However, in the current manufacturing and processing of high-voltage relays, the current traditional production mode still generally relies on manual processing of the inner holes of its components. Manual operation requires workers to hold simple tools such as files and scrapers and remove the burrs on the edge of the inner hole one by one. This pure manual processing method has many drawbacks: on the one hand, since the operation process completely depends on the experience and proficiency of the workers, the processing of each workpiece takes a lot of time and cannot meet the requirements of large-scale modern industrial production, resulting in extremely low overall processing efficiency; on the other hand, it is difficult to ensure stable processing accuracy in manual operation. The operating force and angle of different workers or even the same worker at different times may vary, and it is very easy to have problems such as incomplete burr removal and deviation of the inner hole size, resulting in difficulty in improving the product qualification rate, and further affecting the electrical performance and mechanical stability of the high-voltage relay. At the same time, long-term repetitive manual labor will increase the fatigue of workers, further reducing production efficiency, and there is also a risk of component damage and scrapping due to human negligence, which virtually increases the production cost and is difficult to meet the urgent needs of the industry for high-quality and high-efficiency production.

The nozzles are communicated with the first ion blower and the second ion blower. The nozzles are vertically arranged.

[0013] A processing technology for parts of a high-voltage relay, the processing technology includes the following working steps:

[0014] The first step is to perform automatic feeding of the high-voltage relay parts through the work of the automatic feeding mechanism, and feed the high-voltage relay parts onto the automatic moving platform.

[0015] The second step, after the feeding is completed, the automatic moving platform moves the high-voltage relay parts to the lower part of the grinding component, and performs grinding and deburring work on the burrs on the high-voltage relay parts through the work of the grinding component.

[0016] The third step, after the burr grinding of the high-voltage relay parts is completed, the automatic moving platform works to move the high-voltage relay parts to the lower part of the static elimination component, and performs static elimination work on the high-voltage relay parts through the work of the static elimination component.

[0017] The fourth step, after the static elimination of the high-voltage relay parts is completed, the automatic moving platform works to move the high-voltage relay parts to the lower part of the dust removal component, and performs dust removal work on the dust generated by the high-voltage relay parts through the work of the dust removal component.

[0018] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0019] First, the present invention performs grinding and polishing operations on the burrs on the components of the high-voltage relay, which can be precisely processed: The bristles of the grinding brush are soft and have a certain elasticity, and can conform to the complex shapes and minute details of the high-voltage relay components to precisely grind and polish the burrs. Whether it is the edges, corners or some inaccessible parts of the components, the grinding brush can effectively reach them to ensure that the burrs are completely removed, while not damaging other parts of the components, guaranteeing the accuracy and quality of the components. High-efficiency processing: During the rotation of the grinding brush, multiple bristles act on the burrs simultaneously, greatly improving the processing efficiency compared to manually processing burrs one by one. Moreover, the grinding brush can be installed on automated equipment to achieve continuous and batch processing, meeting the requirements of large-scale production and effectively shortening the production cycle. Surface quality improvement: Through the rotation and grinding of the grinding brush, not only are the burrs removed from the surface of the components, but also a better finish can be obtained. The uniform rotation of the brush makes the grinding force more consistent, enabling the surface of the components to be more flat and smooth, which is beneficial to improving the appearance quality of the components and also helps to enhance the overall performance and reliability of the high-voltage relay.

[0020] Second, when the present invention removes static electricity from the components of the high-voltage relay, rotating the handwheel will drive the ball screw (36) to rotate on the top block and the bottom block, and will drive the linear slider to move downward on the two linear slide rails, thereby moving the position of the static electricity removal device above the components of the high-voltage relay to perform static electricity removal work on the components of the high-voltage relay;

[0021] The high-voltage relay has extremely high requirements for insulation performance. Static electricity is generated on the surface of the ground components due to friction, and it is easy to adsorb conductive dust or metal particles in the environment. These impurities adhere to the surface or key parts such as the inner holes of the components, which will change the local electric field distribution, resulting in a decrease in insulation performance and an increase in the risk of partial discharge. By eliminating static electricity with the static electricity removal device, impurity adsorption can be avoided, the cleanliness of the component surface can be maintained, the electrical insulation performance of the high-voltage relay can be guaranteed, the probability of electrical faults caused by static electricity can be reduced, and its stable operation in a high-voltage environment can be ensured.

[0022] Thirdly, when the present invention removes dust from the components of the high-voltage relay, the driving motor operates to rotate through the second coupling, thereby driving the position of the driving lead screw to move downward. This will drive the moving table to move downward on the two moving slide rails, move the position of the nozzle mounting plate downward, and thus drive the positions of a number of nozzles to move downward. The positions of the nozzles are moved above the components of the high-voltage relay, and the dust on the components of the high-voltage relay is blown outwards. At this time, when the first ion blower and the second ion blower operate, they will generate a large number of ions with positive and negative charges. These ions will combine with the dust particles in the air, causing the dust particles to carry charges. The nozzles direct the air generated by the ion blowers towards the components of the high-voltage relay, forming a directional air flow. Since the dust particles carry charges, there will be a repulsive force between them. At the same time, under the action of the air flow, the dust particles will be blown off the surface of the components, thus achieving the purpose of dust removal. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0035] The following will, with reference to the drawings, elaborate on the technical solutions provided by various embodiments of the present invention for a processing device and process for high-voltage relay components.

[0036] Referring to Figures 1 to 8 As shown, an embodiment of the present invention provides a processing device for high-voltage relay components, including a workbench 1. A grinding assembly 2, a static elimination component 3, and a dust removal component 4 are provided on the top of the workbench 1. The grinding assembly 2, the static elimination component 3, and the dust removal component 4 are arranged in sequence on the top of the workbench 1. An automatic moving platform 6 for driving the high-voltage relay to move is further provided on the top of the workbench 1. The automatic moving platform 6 drives the high-voltage relay to move sequentially towards the grinding assembly 2, the static elimination component 3, and the dust removal component 4. A protective cover 11 is provided on the top of the workbench 1. An automatic feeding mechanism 5 for feeding the high-voltage relay is further provided on the workbench 1.

[0037] It should be noted that the moving platform is a rotary reciprocating structure. The movable platform can reciprocate between the automatic feeding mechanism 5, the grinding assembly 2, the static elimination assembly 3 and the dust removal assembly 4. The automatic feeding mechanism 5 works to feed the high-voltage relay parts onto the moving platform. The moving platform is provided with a fixture for clamping and fixing the high-voltage relay parts. During the processing, the fixture can clamp five high-voltage relay parts at a time and process five high-voltage relay parts at a time.

[0038] In addition, it should be noted that a dust collector is provided at the workbench 1 where the grinding assembly 2 and the dust removal assembly 4 are located. The dust collector can adsorb the generated dust when it works.

[0039] In this embodiment, the grinding assembly 2 includes a first backing plate 20. A grinding support frame 21 is provided on the top of the first backing plate 20. Two symmetrically arranged mounting rails 22 are provided on the side wall of the grinding support frame 21. A lift mounting frame 23 that is slidably engaged is provided between the two mounting rails 22. A lift motor 24 is provided on the top of the grinding support frame 21. A lift screw rod 25 that is rotatably connected is provided on the side wall of the grinding support frame 21. A first coupling 26 is provided between the lift motor 24 and the lift screw rod 25. The lift mounting frame 23 is threadedly connected to the lift screw rod 25.

[0040] In this embodiment, a horizontally arranged mounting plate 27 and a mounting box 28 are provided on the lift mounting frame 23. A grinding motor 29 is provided on the mounting plate 27. Five equally spaced grinding shafts 201 are provided at the bottom of the mounting box 28. A driving gear 202 is provided in each grinding shaft 201 within the mounting box 28. The five driving gears 202 are meshed with each other. The main shaft of the grinding motor 29 is drivingly connected to the top of the grinding shaft 201 at the middle position. A grinding brush 203 is provided at the bottom of the grinding shaft 201.

[0041] In this embodiment, mounting seats 204 are fixedly connected to the bottoms of the two mounting rails 22. Two connecting rods 205 are provided between the mounting seats 204 and the lift mounting frame 23. The connecting rods 205 are slidably engaged with the lift mounting frame 23. A return spring 206 is provided between each pair of connecting rods 205. The bottom and top of the return spring 206 are respectively connected to the mounting seat 204 and the lift mounting frame 23. A moving hole 207 for the grinding brush 203 to pass through is provided on the mounting seat 204.

[0042] When grinding the burrs on the parts of the high-voltage relay, the grinding motor 29 works to drive one of the grinding shafts 201 to rotate in the mounting box 28. When the grinding shaft 201 rotates, it will drive the other drive gears 202 to rotate through the drive gear 202, and when the other drive gears 202 rotate, they will drive the five grinding brushes 203 to rotate;

[0043] After that, when the lifting motor 24 works to drive the first coupling 26 to rotate, it will drive the lifting screw rod 25 to rotate on the grinding support frame 21, and drive the lifting mounting frame 23 to move downward on the two mounting guide rails 22, so that the positions of the five grinding brushes 203 move downward. The five grinding brushes 203 respectively move downward in the five moving holes 207 on the mounting seat 204, and move the grinding brushes 203 into the high-voltage relay parts to polish the burrs on the high-voltage relay parts.

[0044] When the lifting mounting frame 23 moves downward, it will make the lifting mounting frame 23 move downward on the two connecting rods 205, and squeeze the return spring 206, so that the lifting mounting frame 23 moves downward for buffering, ensuring that during the process of polishing the high-voltage relay parts, the grinding brushes 203 will not form hard contact with the high-voltage relay parts and will not cause damage to the high-voltage relay parts.

[0045] The benefits of grinding and polishing the burrs on the high-voltage relay parts are as follows:

[0046] Precise processing: The bristles of the grinding brush 203 are soft and have a certain elasticity, which can fit the complex shape and tiny details of the high-voltage relay parts, and precisely polish and grind the burrs. Whether it is the edge, corner or some inaccessible parts of the parts, the grinding brush 203 can effectively reach, ensure that the burrs are completely removed, and at the same time will not damage other parts of the parts, ensuring the accuracy and quality of the parts.

[0047] Efficient processing: During the rotation of the grinding brush 203, multiple bristles act on the burrs at the same time, which greatly improves the processing efficiency compared with manual single burr processing. Moreover, the grinding brush 203 can be installed on automated equipment to achieve continuous and batch processing, which can meet the needs of large-scale production and effectively shorten the production cycle.

[0048] Surface quality improvement: Through the rotation and grinding of the grinding brush 203, not only the burrs on the surface of the parts are removed, but also a better finish can be obtained. The uniform rotation of the brush makes the grinding force more consistent, which can make the surface of the parts more flat and smooth, which is beneficial to improving the appearance quality of the parts and also helps to improve the overall performance and reliability of the high-voltage relay.

[0049] In this embodiment, the static eliminator assembly 3 includes a second backing plate 30. A static eliminator support frame 31 is provided on the top of the second backing plate 30. Two symmetrically arranged linear slide rails 32 are provided on the side wall of the static eliminator support frame 31. A linearly sliding block 33 is slidably connected between the two linear slide rails 32. A top block 34 and a bottom block 35 are provided on the static eliminator support frame 31. A ball screw 36 is rotatably connected between the top block 34 and the bottom block 35. A hand wheel 37 is provided at the top of the ball screw 36. A connecting frame 38 is provided on the linearly sliding block 33. A static eliminator device 39 is provided on the connecting frame 38.

[0050] When static electricity is removed from the components of the high-voltage relay, rotating the hand wheel 37 will drive the ball screw 36 to rotate on the top block 34 and the bottom block 35, which will drive the linearly sliding block 33 to move downward on the two linear slide rails 32, so as to move the position of the static eliminator device 39 above the components of the high-voltage relay and perform static electricity removal work on the components of the high-voltage relay.

[0051] The high-voltage relay has extremely high requirements for insulation performance. Static electricity is generated on the surface of the ground components due to friction, which easily adsorbs conductive dust or metal particles in the environment. These impurities adhere to the surface or key parts such as the inner hole of the components, which will change the local electric field distribution, resulting in a decrease in insulation performance and an increase in the risk of partial discharge. By eliminating static electricity with the static eliminator device 39, impurity adsorption can be avoided, the surface of the components can be kept clean, the electrical insulation performance of the high-voltage relay can be guaranteed, the probability of electrical failures caused by static electricity can be reduced, and its stable operation in a high-voltage environment can be ensured.

[0052] In this embodiment, a horizontally arranged locking screw 301 is provided on the top block 34. The locking screw 301 is threadedly connected to the top block 34. A rotating handle 302 is provided on the locking screw 301.

[0053] After the position where the static eliminator device 39 moves downward is determined, the rotating handle 302 can be rotated to drive the locking screw 301 to rotate on the top block 34, so that the locking screw 301 locks and fixes the position of the ball screw 36, preventing the ball screw 36 from rotating on the top block 34 and the bottom block 35 due to the shaking of the device during the operation of the device, thereby causing the position of the static eliminator device 39 to move, thus affecting the accuracy of static electricity removal from the components of the high-voltage relay.

[0054] In this embodiment, the dust removal assembly 4 includes a third backing plate 41. A dust removal bracket 42 is provided on the top of the third backing plate 41. Two symmetrically arranged moving slide rails 43 are provided on the dust removal bracket 42. A moving table 44 is provided on the moving slide rails 43 in a sliding fit. A driving lead screw 45 is rotatably connected to the side wall of the dust removal bracket 42. A driving motor 46 is provided on the top of the dust removal bracket 42. A second coupling 47 is provided between the driving motor 46 and the driving lead screw 45;

[0055] A first ion blower 48 and a second ion blower 49 are vertically arranged on the rear side wall of the dust removal bracket 42. A nozzle mounting plate 401 is horizontally arranged on the moving table 44. A number of equally spaced nozzles 402 are provided on the nozzle mounting plate 401. The nozzles 402 are connected to the first ion blower 48 and the second ion blower 49 in communication. The nozzles 402 are vertically arranged.

[0056] When dust removing the parts of the high-voltage relay, the driving motor 46 works and rotates through the second coupling 47, thereby driving the position of the driving lead screw 45 to move downward, which will drive the moving table 44 to move downward on the two moving slide rails 43, move the position of the nozzle mounting plate 401 downward, and thus drive the positions of a number of nozzles 402 to move downward, move the positions of the nozzles 402 above the parts of the high-voltage relay, and blow the dust on the parts of the high-voltage relay outward. At this time, when the first ion blower 48 and the second ion blower 49 work, a large number of ions with positive and negative charges will be generated. These ions will combine with the dust particles in the air, making the dust particles carry charges. The nozzles 402 direct the air generated by the ion blowers to the parts of the high-voltage relay to form a directional air flow. Since the dust particles carry charges, repulsive forces will be generated between them. At the same time, under the action of the air flow, the dust particles will be blown off the surface of the parts, thus achieving the purpose of dust removal;

[0057] Efficient dust removal can be achieved: The nozzles 402 concentrate the air generated by the ion blowers on the surface of the parts of the high-voltage relay to form a targeted air flow, which can directly act on the dust particles and quickly blow them off. The dust on the surface of the parts and some gaps, holes and other parts can be effectively removed, improving the dust removal efficiency; The positive and negative ions generated by the ion blowers can neutralize the static electricity generated on the surface of the parts of the high-voltage relay due to friction and other reasons, prevent the static electricity from adsorbing dust, reduce the accumulation of dust at the source, and at the same time avoid the possible damage to the parts caused by static electricity, such as the breakdown of electronic components caused by static discharge.

[0058] A processing technology for parts of a high-voltage relay, the processing technology includes the following working steps:

[0059] First step, the automatic feeding mechanism 5 works to automatically feed the components of the high-voltage relay, and feed the components of the high-voltage relay onto the automatic moving platform 6;

[0060] Second step, after the feeding is completed, the automatic moving platform 6 moves the components of the high-voltage relay to the lower part of the grinding assembly 2, and the grinding assembly 2 works to grind and remove the burrs on the components of the high-voltage relay;

[0061] Third step, after the burrs on the components of the high-voltage relay are ground, the automatic moving platform 6 works to move the components of the high-voltage relay to the lower part of the static elimination component 3, and the static elimination component 3 works to eliminate the static electricity of the components of the high-voltage relay;

[0062] Fourth step, after the static electricity of the components of the high-voltage relay is eliminated, the automatic moving platform 6 works to move the components of the high-voltage relay to the lower part of the dust removal component 4, and the dust removal component 4 works to remove the dust generated by the components of the high-voltage relay.

[0063] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
