Description

Technical Field

[0001] This invention relates to the field of micro switch spring assembly technology, specifically to a spring assembly mechanism for a micro switch. Background Technology

[0002] Microswitches, as commonly used electromechanical components, are widely used in home appliances, industrial control, automotive electronics, and other fields due to their small contact spacing and rapid action. For spring-type microswitches, the spring is used to reset the microswitch, and the assembly of the spring is generally completed by automated machinery.

[0003] Our company has designed a fully automated assembly equipment for micro switches, which includes the assembly of the micro switch base, terminals, buttons, springs, levers, and covers in all steps. By designing a linear track, different assembly stations are set up on one side of the linear track. The spring assembly mechanism adopts a single-piece feeding and pushing assembly method. However, in the subsequent assembly and production of micro switches, it was found that the time consumed for each spring assembly was too long, which seriously affected the overall assembly efficiency of the micro switch. Therefore, we proposed a spring assembly mechanism for micro switches that can be continuously assembled. Summary of the Invention

[0004] The purpose of this invention is to provide a spring assembly mechanism for a micro switch to solve the problems mentioned in the background art.

[0010] Start the first push cylinder and the second push cylinder. The first push cylinder pushes the first sliding block to move up and down on the first guide rail. The second push cylinder pushes the moving block to move left and right on the track plate. Then the first sliding block and the connecting block drive the reciprocating guide rail to perform circular reciprocating motion, pushing the locking seat to move forward continuously. Since the locking seat has a micro switch base, when the micro switch base reaches the corresponding spring assembly station;

[0011] Furthermore, the turntable mechanism includes a cam divider, a turntable, and a fixed plate. The cam divider is fixedly connected to the inner side of the worktable, the turntable is fixedly connected to the outer side of the upper output end of the cam divider, and the fixed plate is fixedly connected to the upper side of the cam divider.

[0012] Furthermore, the main component includes a fixing block, a connecting plate, a mounting plate, a base plate, and a track block. The upper side of the turntable is fixedly connected to a uniformly distributed fixing block. Both sides of the fixing block are fixedly connected to a connecting plate. The lower side of the connecting plate away from the fixing block is fixedly connected to a mounting plate. A base plate is provided between the two sets of mounting plates. The upper side of the base plate is fixedly connected to a track block.

[0013] Furthermore, the compression mechanism includes an upper fixed plate, a guide rod, a return spring, a moving plate, a compression plate, and a cylindrical block.

[0014] After the cylindrical block leaves the groove of the annular guide rail one, the cylindrical block pushes the base plate to slide upward under the guidance of the guide component two, so that the spring in the upper groove of the track block comes into contact with the compression plate, and the compression plate compresses the spring until the compression plate is in close contact with the upper side wall of the track block.

[0015] The pushing component includes an upper connecting plate and a roller. The upper connecting plate is fixedly connected to the side of the moving plate near the track component, and a roller is rotatably connected to the lower side of the upper connecting plate near the track component.

[0016] Furthermore, the reset component includes a reset connecting plate, a second reset spring, and a second guide rod. The second guide rod is fixedly connected to the upper side of the base plate, and the reset connecting plate is slidably connected to the outer side of the second guide rod. The second reset spring is sleeved between the second guide rod and the reset connecting plate.

[0017] The assembly pusher includes a main push block, a spring push rod, and an auxiliary push rod. The main push block is fixedly connected to the upper side of the reset connecting plate. The auxiliary push rod is fixedly connected to the side of the main push block near the track block. The spring push rod is fixedly connected to the upper side of the main push block.

[0018] When the spring falls into the groove of the spring push rod, the roller is located in the groove of the second annular guide rail, and the cylindrical block is located in the groove of the first annular guide rail. The spring assembly rotates with the turntable. Then, when the roller leaves the groove of the second annular guide rail, the second annular guide rail pushes the roller, the roller drives the upper connecting plate, and the upper connecting plate drives the moving plate to compress the reset spring one and slide on the guide rod one. Under the auxiliary guidance of the guide component one, the compression plate moves synchronously with the moving plate, so that the compression plate just covers the groove exposed on the upper side of the track block.

[0019] Furthermore, the guide component one includes a guide rail two, a middle connecting plate, and a sliding block two. The middle connecting plate is fixedly connected to the lower side of the upper fixed plate. The guide rail two is fixedly connected to the side of the middle connecting plate near the assembly push component. The sliding block two is slidably connected to the outer side of the guide rail two. The sliding block two is fixedly connected to the compression plate.

[0020] The second guide component includes a base plate connecting plate, a sliding block, a guide rail, a guide rod, a reset spring, and a guide block. The base plate connecting plate is fixedly connected to the outer side of the base plate. The sliding block is fixedly connected to the side of the base plate connecting plate away from the base plate. The guide rail is slidably connected to the inner side of the sliding block. The guide rail is fixedly connected to the mounting plate. The guide rod is fixedly connected to the side of the mounting plate near the assembly pusher. The guide block is slidably connected to the outer side of the guide rod. A reset spring is sleeved between the guide rod and the guide block. The guide block is fixedly connected to the base plate connecting plate.

[0021] Furthermore, the track component includes a first annular plate, a first annular guide rail, a second annular plate, and a second annular guide rail. The first annular plate is fixedly connected to the upper side of the worktable, the first annular guide rail is fixedly connected to the outer side of the first annular plate, the second annular plate is fixedly connected to the upper side of the first annular plate, and the second annular guide rail is fixedly connected to the upper side of the second annular plate. Grooves are provided on both the first annular guide rail and the second annular guide rail.

[0022] Furthermore, the spring feeding assembly includes a support rod, a vibratory plate, a guide tube, and a feeding component. The support rod is fixedly connected to the upper side of the worktable, and the vibratory plate is fixedly connected to the upper side of the support rod. The vibratory plate is connected to a guide tube on the side near the turntable mechanism, and a feeding component is provided on the lower side of the guide tube.

[0023] The feeding component includes a fixed support plate, a third pushing cylinder, a bearing block, a fourth pushing cylinder, a limiting push rod, a feeding pipe, and a fixed connecting plate. The upper side of the support rod is fixedly connected to the fixed support plate, the lower side of the fixed support plate is fixedly connected to the third pushing cylinder, the lower output end of the third pushing cylinder is fixedly connected to the bearing block, the outer side of the bearing block is fixedly connected to the fixed connecting plate, the outer side of the fixed connecting plate is fixedly connected to the fourth pushing cylinder, the output end of the fourth pushing cylinder is fixedly connected to the limiting push rod, and the inner side of the bearing block is fixedly connected to the feeding pipe, which is connected to the guide pipe.

[0024] The vibratory feeder sends the spring into the guide tube. The spring inside the guide tube enters the feeding pipe under gravity. Initially, the limit push rod is inserted into the spring, preventing it from falling downwards. Then, the push cylinder four is controlled, causing the limit push rod to move back and forth, thus controlling the spring to move downwards. The push cylinder three is then activated, causing the bearing block to move downwards, aligning the feeding pipe with the spring push rod groove on the corresponding lower track block. The spring then falls into the spring push rod groove, and the cam divider is activated. Since the cam divider consists of a motor, ... It consists of pulleys, belts, input shafts, indexing plates, etc. The motor starts one set of pulleys to rotate, which drives another set of pulleys to rotate through the belt transmission. The other set of pulleys drives the input shaft to rotate. The cam groove on the input shaft pushes the roller on the indexing plate, so that the indexing plate rotates at a preset angle. The indexing plate drives the turntable to rotate synchronously, thus realizing the intermittent rotation of the turntable at a preset angle. Since the turntable is equipped with evenly distributed spring assemblies, the feeding pipe continuously supplies springs to the multiple sets of cyclically rotating spring assemblies.

[0025] Furthermore, the driving source includes a base fixing block and a driving cylinder five. The base fixing block is fixedly connected to the upper side of the fixing plate, and the driving cylinder five is fixedly connected to the upper side of the base fixing block. The annular plate one has a through hole corresponding to the driving cylinder five. The main track has a through groove corresponding to the track block. The track block has a sliding groove corresponding to the spring push rod and the auxiliary push rod.

[0026] When the spring assembly, after being compressed, moves to the position corresponding to the track assembly, the fifth push cylinder is activated. The fifth push cylinder pushes the main push block, which in turn drives the spring push rod and the auxiliary push rod to move outward. The reset connecting plate, which is fixedly connected to the main push block, compresses the second reset spring, which moves synchronously on the second guide rod.

[0027] The spring push rod and auxiliary push rod slide within the track block. The spring push rod pushes the spring to engage with the position of the micro switch base under the guidance of the slide groove within the track block, thereby sending the spring into the micro switch base. Through the continuous rotation of the turntable, the spring assembly operation of subsequent micro switch bases can be performed continuously.

[0028] The cylindrical block moves on the first annular guide rail, and the roller moves on the second annular guide rail.

[0029] Compared with the prior art, the present invention provides a spring assembly mechanism for a micro switch, which has the following beneficial effects.

[0030] 1. The spring assembly mechanism of this micro switch, through the cooperation between the turntable mechanism, spring assembly parts, track parts, spring feeding assembly and push source, achieves the purpose of continuous and fully automated assembly of micro switch springs. It changes the existing spring assembly mechanism that adopts a single feeding and pushing assembly method, solves the problem that the time consumed by a single spring assembly is long, which seriously affects the overall assembly efficiency of the micro switch, and greatly improves the assembly efficiency of the micro switch.

[0031] 2. The spring assembly mechanism of this micro switch, through the cooperation between the spring assembly and the track component, can achieve the positioning and compression of the spring by changing the track, without the need for an additional power source, thus reducing the energy consumption of the equipment.

The bearing block 643 is fixedly connected to the lower output end of the third pushing cylinder 642. The fixed connecting plate 647 is fixedly connected to the outer side of the bearing block 643. The fourth pushing cylinder 644 is fixedly connected to the outer side of the fixed connecting plate 647. The limiting push rod 645 is fixedly connected to the output end of the fourth pushing cylinder 644. The feeding pipe 646 is fixedly connected to the inner side of the bearing block 643. The feeding pipe 646 is connected to the guide pipe 63.

[0072] The vibratory feeder 62 sends the spring into the guide tube 63. The spring inside the guide tube 63 enters the feeding pipe 646 under gravity. Initially, the limiting push rod 645 is inserted into the spring, preventing it from falling downwards. Then, the push cylinder 644 is controlled to move the limiting push rod 645 back and forth, thus controlling the spring to move downwards. The push cylinder 642 is then activated, causing the bearing block 643 to move downwards, so that the feeding pipe 646 aligns with the groove of the spring push rod 442 on the corresponding lower track block 415. The spring then falls into the groove of the spring push rod 442, and the cam divider is then activated. 31. Since the cam divider 31 is composed of a motor, pulleys, belt, input shaft, indexing plate, etc., the motor starts a set of pulleys to rotate, and through the belt transmission, drives another set of pulleys to rotate. The other set of pulleys drives the input shaft to rotate. The cam groove on the input shaft pushes the roller on the indexing plate, so that the indexing plate rotates at a preset angle. The indexing plate drives the turntable 32 to rotate synchronously, thereby realizing the intermittent rotation of the turntable 32 at a preset angle. Since the turntable 32 is provided with evenly distributed spring assemblies 4, the feeding pipe 646 continuously supplies springs to the multiple sets of cyclically rotating spring assemblies 4.

[0073] Furthermore, the driving source 7 includes a base fixing block 71 and a driving cylinder 72. The base fixing block 71 is fixedly connected to the upper side of the fixing plate 33, and the driving cylinder 72 is fixedly connected to the upper side of the base fixing block 71. The annular plate 51 has a through hole corresponding to the driving cylinder 72. The main track 225 has a through groove corresponding to the track block 415. The track block 415 has a sliding groove corresponding to the spring push rod 442 and the auxiliary push rod 443.

[0074] When the spring assembly 4, after being compressed, moves to the position corresponding to the track assembly 2, the push cylinder 5 72 is activated. The push cylinder 5 72 pushes the main push block 441. The main push block 441 drives the spring push rod 442 and the auxiliary push rod 443 to move outward. The reset connecting plate 451, which is fixedly connected to the main push block 441, compresses the reset spring 2 452 and moves synchronously on the guide rod 2 453.

[0075] The spring push rod 442 and the auxiliary push rod 443 slide within the track block 415. The spring push rod 442 pushes the spring to engage with the position of the micro switch base under the guidance of the slide groove in the track block 415, thereby sending the spring into the micro switch base. Through the continuous rotation of the turntable 32, the spring assembly operation of the subsequent micro switch base can be continuously performed.

[0076] The cylindrical block 426 moves on the first annular guide rail 52, and the roller 432 moves on the second annular guide rail 54.

[0077] The specific usage and function of this embodiment are as follows:

[0078] By activating the first cylinder 211, the second cylinder 221 is activated. The first cylinder 211 pushes the first sliding block 213 to move up and down on the first guide rail 212, and the second cylinder 221 pushes the moving block 223 to move left and right on the track plate 222. Then the first sliding block 213 and the connecting block 224 drive the reciprocating guide rail 214 to perform circular reciprocating motion, pushing the locking seat 226 to continuously transport forward. Since the locking seat 226 has a micro switch base locked on it, when the micro switch base reaches the corresponding spring assembly station;

[0079] The vibratory feeder 62 sends the spring into the guide tube 63. The spring inside the guide tube 63 enters the feeding pipe 646 under gravity. Initially, the limiting push rod 645 is inserted into the spring, preventing it from falling downwards. Then, the push cylinder 644 is controlled to move the limiting push rod 645 back and forth, thus controlling the spring to move downwards. The push cylinder 642 is then activated, causing the bearing block 643 to move downwards, so that the feeding pipe 646 aligns with the groove of the spring push rod 442 on the corresponding lower track block 415. The spring then falls into the groove of the spring push rod 442, and the cam divider is then activated. 31. Since the cam divider 31 is composed of a motor, pulleys, belt, input shaft, indexing plate, etc., the motor starts a set of pulleys to rotate, and through the belt transmission, drives another set of pulleys to rotate. The other set of pulleys drives the input shaft to rotate. The cam groove on the input shaft pushes the roller on the indexing plate, so that the indexing plate rotates at a preset angle. The indexing plate drives the turntable 32 to rotate synchronously, thereby realizing the intermittent rotation of the turntable 32 at a preset angle. Since the turntable 32 is provided with evenly distributed spring assemblies 4, the feeding pipe 646 continuously supplies springs to the multiple sets of cyclically rotating spring assemblies 4.

[0080] When the spring falls into the groove of the spring push rod 442, the roller 432 is located in the groove of the second annular guide rail 54, and the cylindrical block 426 is located in the groove of the first annular guide rail 52. The spring assembly 4 rotates with the turntable 32. Then, when the roller 432 leaves the groove of the second annular guide rail 54, the second annular guide rail 54 pushes the roller 432. The roller 432 drives the upper connecting plate 431. The upper connecting plate 431 drives the moving plate 424 to compress the reset spring 423 and slide on the guide rod 422. Under the auxiliary guidance of the guide member 46, the compression plate 425 moves synchronously with the moving plate 424, so that the compression plate 425 just covers the groove exposed on the upper side of the track block 415.

[0081] Subsequently, after the cylindrical block 426 leaves the groove of the annular guide rail 52, the cylindrical block 426 pushes the base plate 414 to slide upward under the guidance of the guide member 47, so that the spring in the upper groove of the track block 415 contacts the compression plate 425, and the compression plate 425 compresses the spring until the compression plate 425 is in close contact with the upper side wall of the track block 415.

[0082] When the spring assembly 4, after being compressed, moves to the position corresponding to the track assembly 2, the push cylinder 5 72 is activated. The push cylinder 5 72 pushes the main push block 441. The main push block 441 drives the spring push rod 442 and the auxiliary push rod 443 to move outward. The reset connecting plate 451, which is fixedly connected to the main push block 441, compresses the reset spring 2 452 and moves synchronously on the guide rod 2 453.

[0083] The spring push rod 442 and the auxiliary push rod 443 slide within the track block 415. The spring push rod 442 pushes the spring to engage with the position of the micro switch base under the guidance of the slide groove in the track block 415, thereby sending the spring into the micro switch base. Through the continuous rotation of the turntable 32, the spring assembly operation of the subsequent micro switch base can be continuously performed.

[0084] The spring push rod 442 slides on the guide rail 461 via the second sliding block 463, and the base plate connecting plate 471 slides on the guide rail 473 via the third sliding block 472. While the base plate connecting plate 471 slides, it drives the guide block 476 fixedly connected to it to compress the reset spring 475 to move synchronously.

[0085] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
