Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and more specifically, to an assembly device for a micro switch. Background Technology

[0002] A micro switch is a type of switch with a small contact gap and a quick-acting mechanism. It operates by using a specified stroke and force to perform the switching action. It is covered by a housing and has a drive rod on the outside. Because the contact gap of the switch is relatively small, it is called a micro switch, also known as a sensitive switch.

[0003] Microswitches consist of a base, a top cover, several pins, a moving contact, and various other parts such as a tension spring. Currently, these parts are usually assembled manually by workers on an assembly line, then glued and sent to a dryer for drying, which is extremely inefficient, time-consuming, and labor-intensive. Utility Model Content

[0004] In summary, to overcome the shortcomings of the prior art, this utility model provides an assembly device that can automatically assemble micro switches.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembly device for a micro switch, comprising an assembly frame, a first robotic arm, a first vibratory feeder, a first conveying mechanism, a dispensing assembly, a second conveying mechanism, and a drying assembly. The first robotic arm and the first vibratory feeder are each provided in multiple units. The first robotic arm is connected to the first vibratory feeder. Multiple first robotic arms are positioned facing the first conveying mechanism. The first conveying mechanism is connected to the second conveying mechanism. The dispensing assembly is positioned facing the second conveying mechanism, and the second conveying mechanism is positioned facing the drying assembly.

[0006] With this setup, each first vibratory feeder contains various components of the micro switch, such as the base, top cover, swing plate, pins, and tension spring. These components are conveyed by the first vibratory feeder to the corresponding first robotic arm. The first robotic arm then places the base on the first conveying mechanism and conveys it to the next station to insert the pins into the base. The process continues, with the swing plate, tension spring, and other pins being continuously conveyed. After assembly, the components are conveyed to the second conveying mechanism, where a dispensing assembly next to the second conveying mechanism applies adhesive to the pins. The dispensing assembly uses a syringe-like structure to apply the adhesive. After dispensing, the components are conveyed to the drying assembly for drying and curing, and then conveyed out by the second conveying mechanism. The entire process is automated and highly efficient. The top cover of the base can be assembled directly or moved to another device for installation after the adhesive has cured. The number and position of the first robotic arm and the first vibratory feeder can be adjusted according to the specific structure of the micro switch.

[0007] Furthermore, it also includes a flipping component, which is rotatably connected to the assembly frame at a position between the first conveying mechanism and the second conveying mechanism, and each side of the flipping component is provided with a flipping groove adapted to a micro switch.

[0008] With this setup, when assembling the micro switch, the base is placed first, and then the pins, sway bar, tension spring, and other parts are inserted from above. At this point, to apply adhesive, the micro switch needs to be flipped so that its bottom side is facing up. The flipping component allows for successful flipping and conveying. The micro switch assembled on the first conveying mechanism will first be conveyed to the flipping slot. Then, the flipping component is driven by a motor and other conventional parts to rotate 180 degrees. In this way, the micro switch in the flipping slot will be flipped and placed on the second conveying mechanism for adhesive application. After the flipping and conveying is completed, the other flipping slot will move to the position of the first conveying mechanism. The structure is simple and the operation is convenient.

[0009] Furthermore, it also includes a third conveying mechanism, which is located between the flipping component and the first conveying mechanism. The third conveying mechanism is disposed toward the flipping groove, which extends through both the front and rear sides toward the direction of the third conveying mechanism.

[0010] With this configuration, the top surface of the flipping slot can be set to a fully enclosed or semi-enclosed state. The micro switch is fed into the flipping slot from the side by the third conveying mechanism. This way, the micro switch will not fall out of the flipping slot when the flipping part rotates, making it more stable. The third conveying mechanism can be set to the form of a telescopic machine plus a pusher block to push the micro switch.

[0011] Furthermore, one of the two flipping slots has a top opening and the other has a bottom opening, the width of which is smaller than that of the micro switch.

[0012] With this design, the opening of the flipping groove facilitates the pushing of the third conveyor mechanism, while also preventing it from scratching parts such as pins and tension springs, thus ensuring greater stability. The opening can be made by setting a protrusion to reduce the width, or by adding an additional groove in the flipping groove to hold a micro switch.

[0013] Furthermore, it also includes a fourth conveying mechanism. The second conveying mechanism includes two conveying rods, and one side of each conveying rod facing the other conveying rod is provided with a conveying groove adapted to the micro switch. The fourth conveying mechanism includes a push block, which pushes the micro switch in the flipping groove into the conveying groove.

[0014] With this setup, the conveying grooves on the two conveying rods on both sides will hold the micro switch, making the conveying more stable. The fourth conveying mechanism will drive the push block to push the micro switch in the flipping groove into the conveying groove through various common structures such as cylinders, hydraulic cylinders, or electric push rods. The operation is simple. When the flipping groove is open, the push block can also move in the opening, making it smoother. The third conveying mechanism can also use the same structure as the fourth conveying mechanism.

[0015] Furthermore, the second conveying mechanism also includes a conveying component, the top of which is provided with a plurality of conveying blocks, the top of which is provided with a positioning groove adapted to a micro switch, and the conveying component moves up and down and horizontally on the assembly frame.

[0016] With this configuration, the conveyor can be connected to various common structures such as cylinders, hydraulic cylinders, electric push rods, or screws to achieve both lifting and horizontal movement. In use, it first descends to disengage from the micro switch, then moves to the bottom of another micro switch and rises to insert the micro switch into the positioning slot. After that, it moves horizontally to the bottom of the dispensing assembly for dispensing, which is more precise and avoids misaligned dispensing. After dispensing, it is pushed towards the drying assembly and descends again for the next set of dispensing. After the next set of dispensing, another micro switch will be conveyed to the side of the previous micro switch. This process is repeated, and a large number of dispensing micro switches are continuously sent over and pushed into the drying assembly. The number of conveyors can be matched with the number of dispensing assemblies.

[0017] Furthermore, it also includes a second robotic arm, which is located between the first conveying mechanism and the second conveying mechanism.

[0018] With this configuration, the second robotic arm can directly move the micro switch assembled on the first conveying mechanism to the second conveying mechanism, or first move it to the third conveying mechanism and then transfer it by the third conveying mechanism, which is more stable and precise.

[0019] Furthermore, the second conveying mechanism also includes a limiting block located on the side of the second conveying mechanism facing the dispensing assembly.

[0020] With this configuration, the limit block can limit the dispensing assembly. The dispensing assembly will stop after pressing against the limit block, ensuring that the nozzle of the dispensing assembly is just above the micro switch.

[0021] Furthermore, the first conveying mechanism includes a first rotating disk, and a plurality of the first robotic arms are arranged sequentially around the first rotating disk.

[0022] With this setup, the first rotating disk is driven by the motor and other parts to rotate on the assembly frame, while the first robotic arm removes the parts from the first vibrating disk and assembles them on the first rotating disk. Using a circular conveyor instead of a strip conveyor reduces the time and space required, and the circular conveyor makes circulation more convenient.

[0023] Furthermore, the first rotating disk is provided with a plurality of assembly blocks arranged around the center of the first rotating disk, and each assembly block is provided with two assembly slots.

[0024] With this setup, the assembly process will take place in the assembly slots on the assembly block. After setting two assembly slots, the base and the bottom pin can be placed in one assembly slot first, and then the swing plate and the top pin can be placed in the other assembly slot, and then the tension spring can be hung. After that, the swing plate with the tension spring installed and the remaining pin are clamped onto the base by the first robotic arm and inserted for installation. The assembly slot for assembling the tension spring can be set to a fitting shape to increase stability and facilitate the installation of the tension spring, or a clamping mechanism can be set to clamp the swing plate after it is placed in and then install the tension spring.

Detailed Implementation

[0033] This specific embodiment is merely an explanation of the present embodiment and is not intended to limit the present embodiment. After reading this specification, those skilled in the art can make modifications to the present embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present embodiment.

[0034] Referring to the accompanying drawings, this utility model provides the following technical solution: an assembly device for a micro switch, including an assembly frame 101, a first robotic arm 102, a first vibratory feeder 103, a first conveying mechanism 104, a dispensing assembly 105, a second conveying mechanism 106, and a drying assembly 107. Several first robotic arms 102 and a first vibratory feeder 103 are provided. The first robotic arms 102 are connected to the first vibratory feeder 103. Several first robotic arms 102 are positioned facing the first conveying mechanism 104. The first conveying mechanism 104 is connected to the second conveying mechanism 106. The dispensing assembly 105 is positioned facing the second conveying mechanism 106, and the second conveying mechanism 106 is positioned facing the drying assembly 107. The above configuration is not limited; a pressing and dust-collecting structure can also be provided next to each conveying mechanism to increase the stability of the micro switch 6 after installation. The pressing structure can also be directly provided on some of the robotic arms, so that the previous installation step is pressed during the clamping and installation process.

[0035] With this setup, during use, each of the first vibratory feeders 103 will contain various components of the micro switch 6, such as the base 601, top cover 602, swing plate 605, various pins 604, and tension spring 606. These components are then conveyed by the first vibratory feeders 103 to the corresponding positions of the first robotic arms 102. The first robotic arms 102 will place the base 601 onto the first conveying mechanism 104, and then convey it to the next station to insert the pins 604 onto the base 601. The process continues, continuously conveying the swing plate 605, tension spring 606, and other pins 604. After assembly, it is then conveyed to the second conveying mechanism. The position of the feeding mechanism 106 is determined by the dispensing component 105 next to the second feeding mechanism 106, which dispenses adhesive to the position of the pin 604. The dispensing component 105 dispenses adhesive through a syringe-like structure. After dispensing, the adhesive is conveyed to the drying component 107 for drying and curing, and then conveyed out by the second feeding mechanism 106 for unloading. The whole process is automated and highly efficient. The top cover 602 can be directly assembled or moved to another device for installation after the adhesive has cured. The number and position of the first robotic arm 102 and the first vibratory plate 103 can be adjusted according to the specific structure of the micro switch 6.

[0036] In this preferred embodiment, the drying component 107 is an ultraviolet irradiation box.

[0037] With this setup, the UV irradiation chamber achieves higher drying efficiency.

[0038] In this preferred embodiment, a flipping component 3 is also included. The flipping component 3 is rotatably connected to the assembly frame 101 at a position between the first conveying mechanism 104 and the second conveying mechanism 106. A flipping groove 301 adapted to the micro switch 6 is provided on each side of the flipping component 3. The above setting is not limited. Only one flipping groove 301 can be provided. In this way, after the conveying is completed, it can be rotated 180 degrees back to the original position.

[0039] With this setup, when assembling the micro switch 6, the base 601 is placed first, and then the pins 604, the swing plate 605, the tension spring 606, and other parts are inserted from above. At this point, to apply glue, the micro switch 6 needs to be flipped so that its bottom surface is facing up. The flipping component 3 can successfully flip and transport it. The micro switch 6 assembled on the first conveying mechanism 104 will first be transported to the flipping slot 301. Then, the flipping component 3 is driven by a motor and other conventional parts to rotate 180 degrees. In this way, the micro switch 6 in the flipping slot 301 will be flipped and placed on the second conveying mechanism 106 for glue application. After the flipping and transport is completed, the other flipping slot 301 will move to the position of the first conveying mechanism 104. The structure is simple and the operation is convenient.

[0040] In a preferred embodiment, the third conveying mechanism 108 is also included. The third conveying mechanism 108 is located between the flipping component 3 and the first conveying mechanism 104. The third conveying mechanism 108 is disposed toward the flipping groove 301, and the flipping groove 301 is disposed through the front and rear sides toward the direction of the third conveying mechanism 108.

[0041] With this configuration, the top surface of the flipping groove 301 can be set to a fully enclosed or semi-enclosed state. The micro switch 6 is fed into the flipping groove 301 from the side by the third conveying mechanism 108. In this way, the micro switch 6 will not fall out of the flipping groove 301 when the flipping part 3 rotates, making it more stable. The third conveying mechanism 108 can be set to a telescopic mechanism plus a pusher to push the micro switch 6.

[0042] In this preferred embodiment, one of the two flipping grooves 301 has a top opening and the other has a bottom opening, and the width of the opening is smaller than that of the micro switch 6.

[0043] With this configuration, the opening of the flipping groove 301 facilitates the pushing of the third conveying mechanism 108, while also preventing it from scratching parts such as the pin 604 and the tension spring 606, thus making it more stable. The opening can be made by setting a protrusion to reduce the width, or by setting an additional groove in the flipping groove 301 to place the micro switch 6.

[0044] In this preferred embodiment, a fourth conveying mechanism 109 is also included. The second conveying mechanism 106 includes two conveying rods 1061. One side of each conveying rod 1061 facing the other conveying rod 1061 is provided with a conveying groove 10611 adapted to the micro switch 6. The fourth conveying mechanism 109 includes a pushing block 1091. The pushing block 1091 pushes the micro switch 6 in the flipping groove 301 into the conveying groove 10611. The above setting is not limited, and the bottoms of the two conveying rods 1061 can also be connected and integrally set.

[0045] With this configuration, the conveying grooves 10611 on the two conveying rods 1061 on both sides will hold the micro switch 6, making the conveying more stable. The fourth conveying mechanism 109 will drive the push block 1091 through various common structures such as cylinders, hydraulic cylinders or electric push rods to push the micro switch 6 in the flipping groove 301 into the conveying groove 10611. The operation is simple. When the flipping groove 301 is open, the push block 1091 can also move in the opening, making it smoother. The third conveying mechanism 108 can also use the same structure as the fourth conveying mechanism 109.

[0046] In a preferred embodiment, the second conveying mechanism 106 further includes a conveying component 1062. The top of the conveying component 1062 is provided with a plurality of conveying blocks 1063. The top of the conveying block 1063 is provided with a positioning groove 10631 adapted to the micro switch 6. The conveying component 1062 moves up and down and horizontally on the assembly frame 101.

[0047] With this configuration, the conveyor 1062 can be connected to various common structures such as cylinders, hydraulic cylinders, electric push rods, or screws to achieve both lifting and horizontal movement functions. In use, it first descends to disengage from the micro switch 6, then moves to the bottom of another micro switch 6 and rises up, so that the micro switch 6 is inserted into the positioning slot 10631. After that, it moves horizontally to the bottom of the dispensing assembly 105 for dispensing, which is more precise and can avoid misaligned dispensing. After dispensing, it is pushed to the direction of the drying assembly 107 and descends again for the next set of dispensing. After the next set of dispensing, another micro switch 6 will be conveyed to the side of the previous micro switch 6. This process is repeated so that a large number of dispensing micro switches 6 are continuously sent over and pushed into the drying assembly 107. The number of conveyors 1062 can be adapted to the number of dispensing assemblies 105.

[0048] In a preferred embodiment, a second robotic arm 110 is also included, which is located between the first conveying mechanism 104 and the second conveying mechanism 106.

[0049] With this configuration, the second robotic arm 110 can hold the micro switch 6 assembled on the first conveying mechanism 104 and move it directly to the second conveying mechanism 106, or move it to the third conveying mechanism 108 first and then transfer it by the third conveying mechanism 108, which is more stable and precise.

[0050] In this preferred embodiment, three dispensing assemblies 105 are provided, and the three dispensing assemblies 105 are arranged sequentially toward the second conveying mechanism 106.

[0051] With this configuration, the three dispensing assemblies 105 can dispense adhesive to the three pins 604 of the micro switch 6 respectively, with each dispensing assembly 105 dispensing adhesive to only one pin 604, resulting in greater stability.

[0052] In a preferred embodiment, the second conveying mechanism 106 further includes a limiting block 1064, which is located on the side of the second conveying mechanism 106 facing the dispensing assembly 105.

[0053] With this configuration, the limit block 1064 can limit the dispensing assembly 105. The dispensing assembly 105 will stop after pressing against the limit block 1064, ensuring that the nozzle of the dispensing assembly 105 is just above the micro switch 6.

[0054] In a preferred embodiment, the first conveying mechanism 104 includes a first rotating disk 1041, and a plurality of first robotic arms 102 are arranged sequentially around the first rotating disk 1041.

[0055] With this configuration, the first rotating disk 1041 will be driven by the motor and other parts to rotate on the assembly frame 101, while the first robotic arm 102 will remove the parts from the first vibrating disk 103 and assemble them on the first rotating disk 1041. Using a circular conveyor instead of a strip conveyor reduces the time and space required, and the circular conveyor is more convenient for circulation.

[0056] In a preferred embodiment, the first rotating disk 1041 is provided with a plurality of assembly blocks 1042 arranged around the center of the first rotating disk 1041, and the assembly block 1042 is provided with two assembly slots 10421.

[0057] With this setup, the assembly process will take place in the assembly slot 10421 on the assembly block 1042. After setting two assembly slots 10421, the base 601 and the bottom pin 604 can be placed in one of the assembly slots 10421 first, and then the swing piece 605 and the top pin 604 can be placed in the other assembly slot 10421, and then the tension spring 606 can be hung on it. After that, the swing piece 605 with the tension spring 606 installed and the remaining pin 604 are clamped together by the first robotic arm 102 and inserted into the base 601 for installation. The assembly slot 10421 for assembling the tension spring 606 can be set to a fitting shape to increase stability and facilitate the installation of the tension spring 606, or a clamping mechanism can be set to clamp the swing piece 605 after it is placed in and then install the tension spring 606.
