Description
Technical Field
[0001] This application relates to the field of explosion-proof capacitors, specifically to an explosion-proof capacitor terminal positioning and installation system and method. Background Technology
[0002] An explosion-proof capacitor is a specially designed capacitor primarily used to prevent explosions or fires caused by internal pressure buildup in the event of a potential internal capacitor failure, thereby ensuring the safety of equipment and personnel. Patent application number 202322913684.1 discloses a connection structure between the core and terminals of an explosion-proof capacitor, specifically revealing the following technical features: when the capacitor heats up during operation, causing the oil to expand, the separator and core move upwards towards the housing, simultaneously driving the lead rod, connecting block, and metal plate upwards. The terminals are fixedly installed, thus allowing the metal plate to separate from the disc. In a preferred embodiment, a spring structure is also disclosed to apply downward pressure to the core, controlling the timing of the core's upward movement so that the core rises only after the oil temperature reaches a predetermined temperature. When assembling such explosion-proof capacitors, it is generally done manually, which is inefficient. Furthermore, manual assembly makes it difficult to strictly control the length of the terminals extending into the housing, resulting in a large deviation between the actual and predetermined oil temperature when the metal plate separates from the disc, thus reducing safety. Existing technologies have also disclosed some tooling for assisting manual installation of terminals, but these toolings are only applicable to one type of explosion-proof capacitor. When the number, position, and size of the terminals change, different toolings need to be developed, which is quite troublesome. Summary of the Invention
[0003] To address the aforementioned deficiencies in the existing technology, this application provides an explosion-proof capacitor terminal positioning and installation system and method, which can improve the installation efficiency and accuracy of the terminals and can adapt to the installation of terminals for different types of explosion-proof capacitors, thus possessing strong practicality.
[0004] To achieve the above objectives, the present invention employs the following techniques:
[0005] An explosion-proof capacitor terminal positioning and installation system is provided for mounting an insulating ring, a metal plate with through holes, and a disc on the terminal, and for mounting the terminal to the top plate of a capacitor with mounting holes. The system includes a base plate and further comprises:
[0006] The first clamping mechanism is located above the base plate and is movable along the length and height of the base plate. It includes multiple first clamping components arranged along the length direction with adjustable spacing. Each first clamping component includes a pair of rotating rods and a pair of clamping rods with the axial direction parallel to the width direction of the base plate. The pair of rotating rods are arranged parallel to each other at intervals along the length direction and are rotated around their own central axis. The clamping rods and rotating rods are connected one-to-one with a first connecting rod.
[0007] The second clamping mechanism is disposed below the first clamping mechanism and is movable along the height direction and the width direction. It includes a plurality of second clamping components respectively disposed directly below the first clamping component and moving along the length direction. Each second clamping component includes a pair of clamping bars for clamping the insulating ring.
[0008] The third clamping mechanism is located below the second clamping mechanism and is used to clamp the top plate of the capacitor.
[0009] The track mechanism is located below the third clamping mechanism and directly below the first clamping mechanism. It includes two sets of track assemblies arranged along the height direction. Each track assembly includes a pair of side strips parallel to the length direction. The pair of side strips are arranged parallel to each other at intervals along the width direction and the spacing is adjustable. The lower part of the opposite side of each pair of side strips is connected to a horizontal strip parallel to the length direction. The upper surfaces of adjacent horizontal strips are coplanar.
[0010] A method for positioning and installing explosion-proof capacitor terminals, implemented using the aforementioned explosion-proof capacitor terminal positioning and installation system, includes the following steps:
[0011] S1. The terminal block to be installed is clamped and fixed in a vertical position by the first clamping assembly, the insulating ring to be installed is clamped and fixed in a coaxial position with the terminal block by the second clamping assembly, the metal plate to be installed is placed in the upper track assembly with the through hole coaxial with the terminal block, the disc to be installed is placed in the lower track assembly with the through hole coaxial with the terminal block, and the top plate of the capacitor is fixed by the third clamping mechanism.
[0012] S2. Adjust the height of the second clamping assembly so that the distance between the insulating ring and the disk is a predetermined value;
[0013] S3. The first clamping assembly, metal plate, and disc are moved synchronously, and the second clamping assembly moves with the first clamping assembly so that the mounting hole of the top plate is coaxial with the terminal block, insulating ring, through hole disc of metal plate;
[0014] S4. Move the first clamping assembly downwards so that the terminal block passes through the insulating ring, the mounting hole in the top plate, and the through hole in the metal plate in sequence, until the lower end of the terminal block contacts the disk.
[0015] S5. Spray hot melt adhesive between the insulating ring and the terminal, and weld the contact point between the disc and the terminal, and wait for the hot melt adhesive and the weld to cool.
[0016] S6. Stop clamping the terminal block and the insulating ring, and move the first clamping assembly and the second clamping assembly out of the position of the top plate. Increase the spacing between adjacent horizontal bars so that they no longer contact the metal plate and the disc. Remove the top plate from the third clamping mechanism.
[0017] The beneficial effects of this invention are as follows:
[0018] The terminal block is installed using a first clamping mechanism, the insulating ring on the terminal block is installed using a second clamping mechanism, the top plate of the explosion-proof capacitor is supported by a third clamping mechanism, and the metal plate and disc are supported by a track mechanism. The terminal block is automatically and accurately installed onto the top plate, which improves the efficiency and accuracy of terminal block installation and can adapt to the installation of terminal blocks of different sizes, quantities and positions.

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.
[0034] like Figure 1 and Figure 2 As shown, one aspect of this embodiment provides an explosion-proof capacitor terminal positioning and installation system for installing an insulating ring 61, a metal plate 62 with through holes, and a disc 63 on a terminal 6, and installing the terminal 6 onto a capacitor top plate 64 with mounting holes. The system includes a base plate 1 for supporting the system, as well as a first clamping mechanism, a second clamping mechanism, a third clamping mechanism, a track mechanism, etc.
[0035] Specifically, such as Figure 1 and Figure 3 As shown, the first clamping mechanism is located above the base plate 1 and is movable along the length and height directions of the base plate 1. It includes multiple first clamping components 2 arranged along the length direction with adjustable spacing. In this example, there are four first clamping components 2. Each first clamping component 2 includes a pair of rotating rods 21 and a pair of clamping rods 22 with the axial direction parallel to the width direction of the base plate 1. The pair of rotating rods 21 are arranged parallel to each other at intervals along the length direction and are rotatable around their own central axis. The clamping rods 22 and the rotating rods 21 are connected one-to-one with first connecting rods 23. In this example, each clamping rod 22 and the corresponding rotating rod 21 are connected by two first connecting rods 23. The first connecting rods 23 are connected to the ends of the clamping rods 22 and the rotating rods 21.
[0036] Since the upper end of the terminal 6 has a terminal block with a large radius, a pair of clamping rods 22 are provided here. By rotating the rotating rod 21, the clamping rods 22 clamp the cylindrical part of the terminal 6 and make the lower end of the terminal block contact the clamping rods 22. In this way, the clamping rods 22 clamp the entire terminal 6, and the clamping rods 22 can clamp the terminal 6 with different radii.
[0037] Preferred, such as Figure 1 and Figure 3 As shown, the first clamping assembly 2 also includes a mounting block 24. The lower end of the mounting block 24 is connected to two mounting frames 25. Each mounting frame 25 has two vertical rods 26 arranged along the height direction. The two vertical rods 26 are slidably fitted with the same drive bar 27. Both ends of the lower surface of the drive bar 27 are connected to two drive frames 28. Both sides of the drive frame 28 are provided with racks 29 along the height direction. The lower end of each mounting frame 25 is connected to a mounting bar 210. Each mounting bar 210 is rotatably connected to two gears 211. The gears 211 are coaxially connected to the two ends of a pair of rotating rods 21 and mesh with the racks 29 respectively. During the rotation of the gears 211, the clamping rods 22 are always parallel and spaced apart along the length direction.
[0038] With this design, by moving the drive bar 27 up and down, the drive bar 27 drives the rack 29 on the drive frame 28 to move up and down, thereby driving the gear 211 to rotate. This causes the two rotating rods 21 to rotate synchronously in opposite directions, thereby controlling the clamping rod 22 to clamp and release the terminal 6. It is not necessary to set up a separate rotation drive mechanism for each rotating rod 21.
[0039] Preferred, such as Figure 1 and Figure 4 As shown, the first clamping mechanism also includes a first mounting frame 212. The first mounting frame 212 has a number of first electric lead screws 213 along the length direction that match the number of first clamping components 2. That is, in this example, there are four first electric lead screws 213. The drive shafts of the first electric lead screws 213 are threadedly fitted with first drive blocks 214. The first drive blocks 214 are respectively connected to the mounting blocks 24. A second drive frame 215 is mounted above the base plate 1. A second electric lead screw 216 is provided on the second drive frame 215 along the length direction. The drive shaft of the second electric lead screw 216 is threadedly fitted with a second drive block 217. A third drive frame 218 is provided on the second drive block 217. A third electric lead screw 219 is provided on the third drive frame 218 along the height direction. The drive shaft of the third electric lead screw 219 is threadedly fitted with a third drive block 220. The third drive block 220 is connected to a second connecting rod 221. The second connecting rod 221 is connected to a drive plate 222. The drive plate 222 is connected to the first mounting frame 212.
[0040] With this design, the first electric lead screw 213 is used to drive the first clamping assembly 2 to move, thereby adjusting the spacing of the first clamping mechanism; the second electric lead screw 216 is used to drive the first clamping mechanism as a whole to move along the length direction; the third electric lead screw 219 is used to drive the drive plate 222 to rise and fall, thereby driving the first clamping mechanism as a whole to move along the height direction; more preferably, a slide bar can be provided on the third drive frame 218 along the height direction, and a slider can be slidably sleeved on the slide bar. The slider is also connected to the third drive block 220 through the rod body, so that the third electric lead screw 219 can drive the drive plate 222 to rise and fall more stably.
[0041] Preferred, such as Figure 5 and Figure 6 As shown, springs 223 are coaxially sleeved on all sides of the vertical rod 26. The springs 223 are connected to the drive bar 27 and the bottom of the mounting frame 25 and are always in a compressed state. A loading plate 224 is provided below one end of the first mounting bracket 212. A first linear cylinder 225 is provided on the loading plate 224 along the height direction. The drive shaft of the first linear cylinder 225 is connected to a pressure bar 226 arranged along the length direction. The pressure bar 226 passes between each drive bar 27 and each mounting block 24.
[0042] Under the action of spring 223, the loading plate 224 will always be at its highest point without external force applied, meaning that the two clamping rods 22 are in contact with each other and in a closed state. The first linear cylinder 225 is used to drive the lower pressure bar 226 to move downward to press the loading plate 224 downward, causing the two clamping rods 22 to separate and be in an open state. When it is necessary to remove or insert the terminal 6, the lower pressure bar 226 is driven to press the loading plate 224 downward. When it is necessary to clamp the terminal 6, the lower pressure bar 226 is driven to move away from the loading plate 224, and under the action of spring 223, the clamping... The rod 22 can clamp the terminal 6; with this design, the opening and closing of each pair of clamping rods 22 can be controlled by a single pressure bar 226, eliminating the need for a separate drive mechanism for each group of first clamping components 2, which greatly simplifies the drive structure of the system; more preferably, a loading plate 224 can also be provided below the other end of the first mounting bracket 212, and a sliding rod can be provided on the loading plate 224 along the height direction, and a slider can be slidably sleeved on the sliding rod, and the slider can be connected to the pressure bar 226, so that the first linear cylinder 225 can drive the pressure bar 226 to rise and fall more stably.
[0043] Preferred, such as Figure 5 As shown, a first loading frame 227 is provided at a predetermined distance below one end of the first mounting frame 212. Two first screws 228 with opposite screw directions are rotatably connected inside the first loading frame 227 along the width direction. The two first screws 228 are coaxially connected and threadedly engaged with first mating blocks 229 respectively. Each first mating block 229 is connected to a limiting rod 230 arranged along the length direction. The limiting rod 230 is located above the clamping rod 22. A first rotating motor 231 is provided on the first loading frame 227. The drive shaft of the first rotating motor 231 is coaxially connected to one of the first screws 228.
[0044] In conventional explosion-proof capacitors, the terminals 6 are generally arranged linearly. However, this system directly uses clamping rods 22 to clamp the terminals 6. Although this ensures that the terminals 6 are at a consistent height, the axial positions of each terminal 6 on the clamping rods 22 are prone to deviation, thus failing to guarantee that the terminals 6 are arranged linearly. Therefore, a first loading frame 227 is provided at a predetermined distance below one end of the first mounting frame 212, and a limiting rod 230 is provided so that the limiting rod 230 is located on both sides of the terminal block of the terminal 6. The first rotating motor 231 drives the first screw 228 to rotate. The distance between the two limiting rods 230 is reduced so that the limiting rods 230 contact the terminal blocks and drive the limiting rods 230 to move until both limiting rods 230 contact both sides of each terminal block. At this point, the terminal blocks 6 are linearly arranged. More preferably, a sliding rod can be set at a predetermined distance below the other end of the first mounting bracket 212 along the width direction, and two sliders can be slidably sleeved on the sliding rod. The two sliders are respectively connected to the limiting rods 230, so that the first rotating motor 231 can drive the two limiting rods 230 to move more stably, thereby adjusting the distance between the two limiting rods 230.
[0045] Specifically, such as Figure 1 , Figure 2 , Figure 8 As shown, the second clamping mechanism is located below the first clamping mechanism and is movable along the height and width directions. It includes multiple second clamping components 3 located directly below the first clamping component 2 and moving along the length direction with it. In this example, there are four second clamping components 3. Each second clamping component 3 includes a pair of clamping bars 31 for clamping the insulating ring 61. More specifically, the second clamping component 3 is located directly below the first clamping component 2 so that when the clamping bars 31 clamp the insulating ring 61, the insulating ring 61 can reach a position coaxial with the upper terminal 6 by moving the second clamping mechanism along the width direction.
[0046] Preferred, such as Figure 1 , Figure 2 , Figures 7-9As shown, two horizontal bars 32 are provided above the base plate 1 along the length direction. Each horizontal bar 32 has a number of movable blocks 33 slidably fitted on it, matching the number of movable blocks 33 in the first clamping assembly 2. In this example, four movable blocks 33 are provided on each horizontal bar 32. Each pair of movable blocks 33 located on different horizontal bars 32 is connected to a connecting block 34. Each connecting block 34 is equipped with a vertical frame 35. Each vertical frame 35 has a linkage rod 36 along the height direction. Each linkage rod 36 has a first linkage block 37 connected to the mounting block 24 and a second linkage block 38 connected to a mating rod 39 along the width direction. Each mating rod 39 has a mating sleeve 310 slidably fitted on it. Each mating sleeve 310 has a third linkage block 311 connected to its lower part. Each third linkage block 311 has a mounting plate 312 connected to its lower part. Each mounting plate 312 has two toothed pillars 313 rotatably connected to one end of each other, with their axes parallel to the height direction and meshing with each other. The two toothed pillars 313 are respectively connected to one end of a pair of clamping bars 31. Further preferred... The same pair of clamping bars 31 are symmetrically arranged about a symmetrical surface perpendicular to the length direction; each mounting plate 312 is equipped with a second rotating motor 314 and its drive shaft is coaxially connected to one of the toothed columns 313. The second rotating motor 314 is used to drive the toothed column 313 to rotate, thereby controlling the opening and closing of the pair of clamping bars 31; a third drive frame 218 is connected to a third connecting rod 315, the third connecting rod 315 is connected to a fourth drive frame 316, a fourth electric lead screw 317 is provided on the fourth drive frame 316 along the width direction, the drive shaft of the fourth electric lead screw 317 is threadedly engaged with a fourth drive block 318, the fourth drive block 318 is connected to a fifth drive frame 319, a fifth electric lead screw 320 is provided on the fifth drive frame 319 along the height direction, the drive shaft of the fifth electric lead screw 320 is threadedly engaged with a fifth drive block 321, the fifth drive block 321 is connected to a loading rod 322 parallel to the length direction, and the third linkage block 311 is slidably sleeved on the loading rod 322.
[0047] In this design, the fourth electric lead screw 317 drives the second clamping mechanism to move along the width direction, that is, drives all clamping bars 31 to move synchronously, so that the insulating ring 61 reaches the position where it is coaxial with the upper terminal 6; the fifth electric lead screw 320 drives the second clamping mechanism to move along the height direction to adjust the height of all clamping bars 31; at the same time, when the first clamping assembly 2 moves along the length direction, through the linkage of the first linkage block 37, linkage rod 36, second linkage block 38, mating rod 39, and mating sleeve 310, the corresponding second clamping assembly 3 will be driven to move along with it, without affecting the first clamping assembly 3. The second clamping assembly 3 moves along the width direction and the height direction; more preferably, a third connecting rod 315 can be set on the other side of the third drive frame 218, and a slide rod is connected to the third connecting rod 315 along the width direction. A slider is slidably sleeved on the slide rod, and another slide rod is connected to the slider along the height direction. A slider is slidably sleeved on the slide rod, so that the slider is connected to the end of the loading rod facing away from the third linkage block 311, thereby enabling the fourth electric lead screw 317 and the fifth electric lead screw 320 to drive the second clamping mechanism to move along the width direction and the height direction more stably.
[0048] Specifically, such as Figure 1 and Figure 10 As shown, the third clamping mechanism is located below the second clamping mechanism and is used to clamp the top plate 64 of the capacitor. More specifically, the surface of the top plate 64 in the clamping and fixed state should be parallel to the bottom plate 1, and the array direction of the mounting holes on it should be parallel to the length direction. During the movement of the first clamping mechanism along the length direction, the terminal 6 it clamps can move to a position coaxial with the mounting hole.
[0049] Preferred, such as Figure 1 and Figure 10As shown, the third clamping mechanism includes a C-shaped frame 5 and a lifting plate 51. In this example, there are two C-shaped frames 5 and two lifting plates 51. Each C-shaped frame 5 includes a vertical plate perpendicular to the width direction and a horizontal plate perpendicularly connected to the upper and lower ends of the vertical plate. The two lifting plates 51 are respectively spaced parallel between the horizontal plates. Each C-shaped frame 5 is provided with a second linear cylinder 52 along the height direction. The drive shaft of the second linear cylinder 52 is coaxially connected to the lifting plate 51 to drive the lifting plate 51 to move along the height direction, thereby causing the lifting plate 51 and the horizontal plate below to clamp the top plate 64. A sixth drive frame 53 is installed above the bottom plate 1. The sixth drive frame 53 is provided with a first linear cylinder 52 along the width direction. The sixth electric lead screw 54 has a drive shaft threadedly fitted with a sixth drive block 55. A seventh drive frame 56 is mounted on the sixth drive block 55, and a seventh electric lead screw 57 is mounted on the seventh drive frame 56 along the height direction. A seventh drive block 58 is threadedly fitted to the drive shaft of the seventh electric lead screw 57, and a fourth connecting rod 59 is connected to the seventh drive block 58. Both C-shaped frames 5 are connected to the fourth connecting rod 59. With this design, the sixth electric lead screw 54 is used to drive the third clamping mechanism to move along the width direction, and the seventh electric lead screw 57 is used to drive the third clamping mechanism to move along the height direction. This allows the third clamping mechanism to be moved to the working position or the loading / unloading position, facilitating the installation and disassembly of the top plate 64.
[0050] Specifically, such as Figure 1 and Figure 11 As shown, the track mechanism is located below the third clamping mechanism and directly below the first clamping mechanism. It includes two sets of track assemblies 4 arranged along the height direction. Each track assembly 4 includes a pair of side strips 41 parallel to the length direction. The pair of side strips 41 are arranged parallel to each other along the width direction and the spacing is adjustable. The lower part of the opposite side of each pair of side strips 41 is connected to a horizontal strip 42 parallel to the length direction. The upper surfaces of adjacent horizontal strips 42 are coplanar.
[0051] With this design, the pair of side strips 41 and cross strips 42 located at the top are used to support the metal plate 62, so that the metal plate 62 can slide on it and slide to the position where the through hole is coaxial with the terminal 6; the pair of side strips 41 located at the bottom are used to support the disc 63, so that the disc 63 can slide on it and slide to the position where it is coaxial with the terminal 6.
[0052] Preferred, such as Figure 1 and Figure 11As shown, two second loading racks 43 are installed above the base plate 1. Each second loading rack 43 has two second screws 44 with opposite thread directions rotatably connected along the width direction. The two second screws 44 in the same second loading rack 43 are coaxially connected and threadedly fitted with second mating blocks 45. The side strips 41 are connected to the second mating blocks 45 respectively. Each second loading rack 43 is equipped with a third rotary motor 46. The drive shaft of the third rotary motor 46 is coaxially connected to one of the second screws 44 on the second loading rack 43. With this design, the spacing of a pair of side strips 41 can be adjusted by driving the second screws 44 to rotate through the third rotary motor 46. More preferably, two sliding rods can be set above the base plate 1 along the width direction, and two sliders can be slidably fitted on the sliding rods. The sliders are respectively connected to the end of the side strip 41 facing away from the second mating block 45, so that the third rotary motor 46 can drive the side strips 41 to move more stably to adjust the spacing of a pair of side strips 41.
[0053] Preferred, such as Figure 1 and Figure 12 As shown, each adjacent horizontal bar 42 is provided with a number of magnetic pillars 47 matching the number of the first clamping assembly 2 and whose axial direction is parallel to the height direction. That is, in this example, each adjacent horizontal bar 42 is provided with four magnetic pillars 47. The upper surface of the magnetic pillar 47 is coplanar with the upper surface of the horizontal bars 42 on both sides. The upper magnetic pillars 47 are respectively located directly below the first clamping assembly 2, and the lower magnetic pillars 47 are respectively spaced apart from the upper magnetic pillars 47 in the length direction by a predetermined distance. Each connecting block 34 is connected to two support rods 48. One of the support rods 48 on each connecting block 34 is connected to a fourth rotating motor 49 arranged along the height direction. The drive shaft of the fourth rotating motor 49 is respectively connected to the upper magnetic pillar 47, and the other support rod 48 on each connecting block 34 is respectively connected to the lower magnetic pillar 47.
[0054] With this design, the magnetic column 47 is used to attract the metal plate 62 and the disk 63, driving them to move on the track assembly 4; the magnetic column 47 is connected to the corresponding connecting block 34 through the support rod 48, so that the magnetic column 47 can follow the first clamping assembly 2 to move along the length direction; the fourth rotating motor 49 is used to drive the magnetic column 47 located below and the disk 63 attracted on it to rotate, so as to facilitate the installation of the disk 63 on the lower end of the terminal post 6 and the fixing of the insulating ring 61 on the terminal post 6 at a predetermined position.
[0055] Preferred, such as Figure 1 and Figure 12As shown, the mounting plate 312 is equipped with a glue gun mechanism 323. The working end of the glue gun mechanism 323 is connected to a glue gun tube 324, and the glue gun tube 324 is connected to a glue gun head 325. The glue gun head 325 is located at a predetermined position outside the front end of the mounting plate 312. The mounting plate 312 is also equipped with a welding gun mechanism 410. The working end of the welding gun mechanism 410 is connected to a welding gun tube 411. Each connecting block 34 is connected to a guide crossbar 412 arranged along the width direction. A movable sleeve 413 is slidably sleeved on the guide crossbar 412. The lower surface of the mounting plate 312 is connected to a guide crossbar 412 arranged along the height direction. The guide vertical rods 414 are provided, and each guide vertical rod 414 is slidably fitted with a connecting sleeve 415. The connecting sleeves 415 are respectively connected to the movable sleeves 413. More preferably, in this example, each mounting plate 312 is connected to two guide vertical rods 414, and each movable sleeve 413 is connected to two connecting sleeves 415.

The movable sleeve 413 is provided with a welding gun head 416 connected to the welding gun tube 411. The welding gun head 416 is set at a predetermined position outside one side of the pair of side strips 41 located above.
[0056] With this design, the glue gun mechanism 323 is used to supply hot melt adhesive to the glue gun head 325 through the glue gun tube 324, so that the glue gun head 325 can spray hot melt adhesive on the connection point between the insulating ring 61 and the terminal 6, and fix the insulating ring 61 to the terminal 6; the welding gun mechanism 410 is used to supply power to the welding gun head 416 through the welding gun tube 411, so that the welding gun head 416 can weld the connection point between the disc 63 and the lower end of the terminal 6; the specific structures of the glue gun mechanism 323 and the welding gun mechanism 410 are both existing technologies, so they will not be described in detail here.
[0057] Taking the installation of three terminals 6 on the top plate 64 as an example, the workflow of this explosion-proof capacitor terminal positioning and installation system includes: selecting three first clamping components 2 and adjusting their spacing through the first electric lead screw 213; opening a pair of clamping rods 22 of the three first clamping components 2; manually or using an external mechanical device, inserting the terminals 6 to be installed between the pair of clamping rods 22; adjusting the spacing of the limiting rods 230 to make the three terminals 6 linearly arranged; and then closing the clamping rods 22 to complete the fixing of the terminals 6. When the terminal block 6 is vertical, the spacing matches the spacing of the through holes on the metal plate 62. Using manual or mechanical means, place the three metal plates 62 onto the upper track assembly 4, adjusting the position of the metal plates 62 and the spacing of the side strips 41 of the upper track assembly 4 so that the through holes on the three metal plates 62 are coaxial with the terminal block 6 and attract the upper magnetic post 47. Using manual or mechanical means, place the three discs 63 onto the lower track assembly 4, adjusting the position of the discs 63 and the spacing of the side strips 41 of the lower track assembly 4. The spacing of the side strips of the guide component 4 is such that the three disks 63 are coaxial with the terminal 6 and coaxially attracted to the magnetic post 47 located below. Based on the required length of the terminal 6 to extend into the housing, the height of the second clamping component 3 is adjusted, and the second clamping component 3 is moved along the width direction. Insulating rings 61 are then placed between the corresponding clamping strips 31 using manual labor or external mechanical devices, ensuring that the insulating rings 61 are coaxial with the terminal 6, and that the distance between their lower surface and the upper surface of the disk 63 matches the required length of the terminal 6 to extend into the housing. The internal length is such that the working end of the glue gun head 325 is located at the upper end of the inner ring surface of the insulating ring 61, and the working end of the welding gun head 416 is located at the predetermined contact point between the upper surface of the disc 63 and the edge of the terminal 6. Then, the clamping strip 31 is closed to clamp and fix the insulating ring 61. The top plate 64 with pre-drilled through holes is placed between the lifting plate 51 and the horizontal plate below the C-shaped frame 5 using manual labor or external mechanical devices. The lifting plate 51 is moved to fix the top plate 64, and the arrangement direction of the mounting holes on the top plate 64 should be parallel to the arrangement direction of the terminal 6.
[0058] The second electric screw 216 drives all the terminals 6, insulating rings 61, metal plates 62, and discs 63 to move synchronously. The sixth electric screw 54 and the seventh electric screw 57 drive the top plate 64 to move, making the terminals 6, insulating rings 61, through holes on metal plates 62, discs 63, and mounting holes on top plate 64 coaxial. At this time, the third electric screw 219 drives the terminals 6 to move downward synchronously. The terminals 6 pass through the insulating rings 61, mounting holes on top plate 64, and through holes on metal plates 62 in sequence until the lower end contacts the upper surface of discs 63 and the driving stops.
[0059] Hot melt adhesive is sprayed onto the contact point between the terminal 6 and the insulating ring 61 using the glue gun head 325. The contact point between the terminal 6 and the disc 63 is then welded using the welding gun head 416. After the hot melt adhesive cools, the insulating ring 61 and the disc 63 are initially fixed to the terminal 6. However, the fixation is not yet secure enough. Therefore, the clamping rod 22 and clamping strip 31 need to be released from their grip on the terminal 6 and the insulating ring 61. The magnetic column 47 located above is rotated so that the terminal 6, the insulating ring 61, and the disc 63 rotate coaxially. While rotating, the glue gun head 325 continues to spray hot melt adhesive, and the welding gun head 416 continues to weld, so that the insulating ring 61 and the disc 63 are more stably fixed to the terminal 6.
[0060] After fixing, move the clamping rod 22 upward to move it out of both sides of the terminal block 6, increase the spacing between the side strips 41 of the two track assemblies 4, and move the top plate 64 upward. When the top plate 64 contacts the insulating ring 61 and continues to move, it will drive the disc 63 to separate from the magnetic column 47. After the disc 63 and the metal plate 62 are completely separated from the side strips 41 of the two track assemblies 4 and enter the space above them, use the sixth electric screw 54 to drive the top plate 64 to a point that is easy to unload. At this time, the top plate 64 with the terminal block 6 installed can be removed.
[0061] Subsequently, it is only necessary to connect the insulating ring 61 to the surface of the top plate 64 with screws, install the top plate 64 to the top of the explosion-proof capacitor housing, install the metal plate 62 onto the lead rod on the capacitor core, and then add the spring structure. These specific installation processes are not within the scope of the discussion of installing the terminal block 6 in this embodiment, so they will not be elaborated here.
[0062] When continuously positioning and installing the terminals 6 of a single type of explosion-proof capacitor, subsequent operations no longer require individually driving each first clamping component 2 to move, nor do they require driving the second clamping component 3 to move via the fourth electric screw 317 and the fifth electric screw 320, effectively optimizing the system's drive process. Furthermore, the system can adapt to installing terminals 6 of different sizes, thus eliminating the need for a separate new system.
[0063] like Figure 13 As shown, another aspect of this embodiment provides a method for positioning and installing explosion-proof capacitor terminals, implemented using the explosion-proof capacitor terminal positioning and installation system described in the preceding embodiment, including the following steps:
[0064] S1. The terminal 6 to be installed is clamped and fixed in a vertical position by the first clamping assembly. The insulating ring 61 to be installed is clamped and fixed in a coaxial position with the terminal 6 by the second clamping assembly. The metal plate 62 to be installed is placed in the upper track assembly 4 with the through hole coaxial with the terminal 6. The disc 63 to be installed is placed in the lower track assembly 4 with the through hole coaxial with the terminal 6. The top plate 64 of the capacitor is fixed by the third clamping mechanism.
[0065] S2. Adjust the height of the second clamping assembly so that the distance between the insulating ring 61 and the disk 63 is a predetermined value, which matches the length of the terminal 6 that needs to be inserted into the housing.
[0066] S3. The first clamping assembly 2, metal plate 62, and disc 63 move synchronously. The second clamping assembly 3 moves with the first clamping assembly 2, so that the mounting hole of the top plate 64 is coaxial with the terminal 6, insulating ring 61, through hole disc 63 of metal plate 62.
[0067] S4. Move the first clamping assembly 2 downward so that the terminal 6 passes through the insulating ring 61, the mounting hole of the top plate 64, and the through hole of the metal plate 62 in sequence until the lower end of the terminal 6 contacts the disk 63.
[0068] S5. Spray hot melt adhesive between the insulating ring 61 and the terminal 6, and weld the contact point between the disc 63 and the terminal 6, and wait for the hot melt adhesive and the weld point to cool.
[0069] S6. Stop clamping the terminal block 6 and the insulating ring 61, and move the first clamping assembly 2 and the second clamping assembly 3 out of the position of the top plate 64. Increase the spacing between the adjacent horizontal bars 42 so that they no longer contact the metal plate 62 and the disc 63. Remove the top plate 64 from the third clamping mechanism.
[0070] This design allows for the positioning and installation of terminal 6, while strictly controlling the length of terminal 6 extending into the housing.
[0071] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
