Technical Field

[0001] This technical solution relates to the field of assembly equipment technology, specifically to a relay switch cover assembly system. Background Technology

[0002] A relay is an electrical control device that, when the input excitation quantity changes to a specified degree, causes a predetermined step change in the controlled quantity in the electrical output circuit. It has an interactive relationship between the control system (input circuit) and the controlled system (output circuit). Commonly used in automated control circuits, it is essentially an "automatic switch" that uses a small current to control a large current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits. For example, Chinese Patent 2018220053753.

[0043] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0044] like Figure 1 As shown, a relay switch cover assembly system mainly utilizes the cooperation of mechanical devices to assemble the connecting piece assembly and bolt assembly onto the switch cover body 7, thereby completing the assembly of the relay switch cover.

[0045] The system mainly includes a connecting piece assembly device 2 for assembling connecting piece assemblies and a bolt assembly device 1 for assembling bolts. In order to link the two devices together, a semi-finished product flipping and unloading device 600 is also provided. This device can flip the semi-finished switch cover assembled by the connecting piece assembly device 2 and transport it to the bolt assembly device 1. Finally, the finished product unloading device 12 is used to transport and unload the assembled switch cover for unified overall storage.

[0046] First, let's briefly introduce the structure of the switch cover 7: Similar to the planar contact relay disclosed in Chinese Patent 2018220053753, the switch cover 7 of this technical solution is similar to the upper housing in the Chinese patent. Both have a protruding boss in the middle, with through holes 8 for mounting bolts (static contacts) on the boss. Through holes 9 for mounting connecting plate assemblies are located on both sides of the boss, along with screw holes distributed around the perimeter for threading screws, thus connecting to the relay body. A countersunk groove 10 is provided at the upper end of the screw holes to accommodate the end of the screw. Figure 3 .

[0047] like Figure 1 As shown, the connecting piece assembly equipment 2 will be introduced next. This equipment mainly includes: frame 3, rotating device 100, rivet feeding device 200, cover feeding device 300, connecting piece feeding device 400 and riveting device 500. The rotating device 100 is mounted on the frame 3, which has several circumferentially arranged workstations. Each workstation is equipped with a tooling fixture and a placement seat 104, mainly for fixing the switch cover 7 and rivets. A rivet feeding device 200, a cover feeding device 300, a connector feeding device 400, and a riveting device 500 are arranged sequentially on the outer periphery of the rotating device 100 to fix the connector assembly on the switch cover 7, thereby forming a semi-finished switch cover.

[0048] The structures of several devices will be analyzed in detail below.

[0049] like Figure 2 As shown, the structure of the rotating device 100 is as follows: The rotating device 100 mainly includes: a drive mechanism 101, a turntable 102, a positioning mechanism 103, a placement seat 104, tooling fixtures and clamping components 106, etc.

[0050] The drive mechanism 101 mainly adopts an indexing turntable. In this embodiment, a six-indexing turntable is used to drive the turntable 102 to rotate. Several placement seats 104 are evenly divided on the upper surface of the turntable 102. A positioning pin 1012 is provided on each placement seat 104. The positioning pin 1012 is vertically installed on the placement seat 104 through a bushing. The upper end of the positioning pin 1012 protrudes from the upper surface of the placement seat 104. The installation position of the positioning pin 1012 is to match the through hole 29 on the switch cover 7 to ensure that the rivet can pass through the through hole 29.

[0051] To ensure the accuracy of the rotation angle of turntable 102 each time, several positioning parts 107 are provided on turntable 102. A positioning mechanism 103 is installed on the plane of frame 3. The positioning mechanism 103 includes a cylinder and a positioning cylinder. The positioning cylinder is installed on the output end of the cylinder and drives it to move up and down, thereby cooperating with the positioning parts 107 to achieve accurate rotation of turntable 102. The upper end of the positioning cylinder is hemispherical, and the positioning part 107 is a round hole that fits the positioning cylinder.

[0052] After the turntable rotates once, the cylinder drives the positioning cylinder to move upward, and the positioning cylinder enters the round hole through the upper end of the hemisphere. If there is a small rotation error in the turntable 102 during the entry, it will be corrected during the process of the positioning cylinder entering the round hole through the upper end of the hemisphere, so as to ensure the accuracy of the rotation of the turntable 102.

[0053] A tooling fixture is provided in the workstation. The tooling fixture is a sliding positioning mechanism 105. The sliding positioning mechanism 105 is located inside the placement seat 104 and mainly includes: a sliding seat 1051, a slide rail 1052 and a positioning pressure plate 1053. The sliding seat 1051 is fixed on the turntable 102 and located inside the placement seat 104. A vertical groove is provided on the sliding seat 1051, and the slide rail 1052 is installed in the groove. It can move up and down along the groove under the action of the external force of the clamping assembly 106. The end of the positioning plate 1053 is fixedly connected to the slide rail 1052. The positioning plate 1053 is placed above the placement seat 104 and can move with the slide rail 1052.

[0054] A hole 1054 is provided in the middle of the positioning plate 1053 for the boss of the switch cover 7 to pass through. In this embodiment, the hole 1054 is designed as a U-shaped groove. A circular boss 1055 is provided at both the opening and bottom of the U-shaped groove. A notch 1056 is provided in the middle of the side wall of the U-shaped groove.

[0055] When the switch cover 7 is placed on the placement seat 104, one end of the rivet protrudes through the through hole 9, and at the same time, the circular boss 1055 presses against the recess 10, and the side wall of the circular boss 1055 abuts against the side wall of the boss of the switch cover 7, thereby realizing the positioning and fixing of the switch cover 7 on the placement seat 104. The design of the U-shaped groove and related structures is to ensure the accuracy of the fixed position of the switch cover 7 and to ensure the accuracy of subsequent parts assembly.

[0056] The aforementioned clamping assembly 106 mainly includes a fixed bracket and a cylinder. The fixed bracket is installed on the frame 3 and drives the mechanism 101. The fixed bracket does not rotate with the turntable. The cylinder is installed at the end of the fixed bracket and placed above the slide rail 1052. A pressing head is installed at the output end of the cylinder. The pressing head is used to contact the slide rail 1052. The pressing head can be made of silicone or other materials to play a buffering role. The cylinder is used to push the slide rail 1052 down, so that the positioning plate 1053 presses against the upper end of the switch cover 7 of the placement seat 104.

[0057] like Figure 1 and Figure 4 As shown, in order to achieve automatic rivet feeding, a rivet feeding device 200 is provided. The specific structure of the rivet feeding device 200 is as follows: The rivet feeding device 200 includes: a rivet feeding mechanism 201, a rivet feeding mechanism 202, and a rivet clamping and feeding mechanism 203; The rivet feeding mechanism 201 is mainly a vibratory feeder mechanism used to arrange and transport rivets neatly. The rivet feeding mechanism 202 is connected to the rivet feeding mechanism 201. The rivets arranged by the rivet feeding mechanism 201 are transported to the rivet feeding mechanism 202, which transports them as a whole to the clamping position of the rivet feeding mechanism 202 one rivet at a time. Then the rivet clamping and feeding mechanism 203 accurately clamps the single rivet in the clamping position and sends it to the positioning pin 1012 of the placement seat 104.

[0058] The feeding mechanism mainly includes: a feeding bracket 204, on which a feeding groove 205 and a positioning groove 206 are provided. The feeding groove 205 and the positioning groove 206 intersect each other, but in this embodiment they are arranged perpendicularly to each other. A rivet feeding mechanism 201 is connected to the feeding groove 205 to allow rivets to enter the feeding groove 205. A pushing component 207, a pushing component 208, a positioning component 209, and a positioning component 210 are provided on the feeding bracket 204. The pushing component 207 includes a pushing plate and a pushing member. Part of the pushing plate extends into the feeding groove 205. The pushing member pushes the pushing plate to move within the feeding groove 205, pushing a single rivet into the positioning groove 206.

[0059] The second pusher assembly 208 and the first positioning assembly 209 are respectively installed at both ends of the first positioning groove 206. The second pusher assembly 208 includes a second pusher plate and a second pusher. The second pusher plate extends into the first positioning groove 206, and the second pusher pushes it to move in and out of the first positioning groove 206 to push the rivets that have entered the first positioning groove 206 to the clamping position.

[0060] Positioning component 1 209 includes a positioning baffle and a pushing component 3. The positioning baffle is provided with a U-shaped fork groove. The pushing component 3 pushes the positioning baffle to move in the positioning long groove 1 206. The pushing component 2 208 pushes the rivet into the U-shaped fork groove. Positioning component 210 is installed below positioning slot 206 and mainly includes positioning pin 2 and pusher 4. Pusher 4 controls positioning pin 2 to extend into positioning slot 206 and into the rivet in the clamping position or to retract.

[0061] The rivet is accurately fixed in the clamping position by positioning component 1 209 and positioning component 2 210. Since the vibrating plate vibrates, this design can also avoid shaking and ensure accurate clamping.

[0062] In this embodiment, the aforementioned actuating components are all cylinders.

[0063] The structure of the rivet clamping and feeding mechanism 203 is as follows: The rivet clamping and feeding mechanism 203 includes a rivet feeding slide 211, a rivet lateral movement assembly 212, a rivet vertical movement assembly 213, and a clamping assembly 214. The rivet feeding carriage 211 is movably mounted on the feeding bracket 204 via a guide rail slider structure and is driven to move by a cylinder. The rivet lateral movement component 212 is horizontally mounted on the upper end of the feeding bracket 204 and uses a motor screw transmission mechanism. The rivet lateral movement component 212 drives the rivet up-down movement component 213 to move laterally. The rivet up-down movement component 213 uses a cylinder or screw transmission mechanism, and a clamping component 214 is installed on its output end. The clamping component 214 uses a pneumatic gripper, and two C-shaped clamping arms 215 are installed on the gripper. The slots of the C-shaped clamping arms 215 are arranged opposite each other, and the lower ends of the two C-shaped clamping arms 215 are opened in grooves that match the shape of the rivet. The grooves between the C-shaped clamping arms 215 can accurately clamp the rivet in the clamping position.

[0064] When placing the rivet onto the positioning pin 1012, due to the design of the positioning pressure plate 1053, it would be impossible to accurately place the rivet using ordinary clamps. The design of the C-shaped clamping arms 215 in this embodiment creates a clearance space 216 between the two C-shaped clamping arms 215. During placement, the positioning pressure plate 1053 will be positioned within the clearance space without interference, thus enabling rivet loading.

[0065] Because the assembly of the switch cover requires high precision, the accuracy of the movement position of the components is also very important. The positioning design of the rivet feeding device 200 ensures that the process of feeding the rivet and installing it into the positioning pin 1012 is precise, so that the subsequent assembly of the components can proceed accurately and normally.

[0066] like Figure 1 , Figure 5 and Figure 6 As shown, the cover feeding device 300 mainly places the switch cover 7 accurately onto the placement seat 104 where the rivets have been placed, and its structure is as follows: The cover feeding device 300 includes a cover material handling mechanism 301, an ejection positioning mechanism 302, and a cover clamping and feeding mechanism 303; The material handling mechanism 301 is mainly a vibratory feeder.

[0067] The ejection positioning mechanism 302 mainly receives the switch cover 7 conveyed by the vibratory feeder. The ejection positioning mechanism 302 mainly includes a cover ejection seat 304 and a cover ejection assembly 305. The cover ejection seat 304 has a cover receiving groove 306, which can accommodate one switch cover 7 at a time. The cover ejection assembly 305 is installed below the cover ejection seat 304 and is partially placed in the receiving groove. The cover ejection assembly 305 includes a cylinder and a cover positioning seat. The cover positioning seat is connected to the output end of the cylinder. The upper end of the cover positioning seat extends into the cover ejection seat 304. Two positioning pins 307 are protruding from the upper end of the cover positioning seat. The positions of the two positioning pins 307 correspond to the through holes 2 and 9 on the switch cover 7.

[0068] When the switch cover 7 enters the receiving groove, the cylinder lifts the cover positioning seat from the bottom of the receiving groove, and at the same time, the positioning pins 307 are inserted into the corresponding through holes 9, thereby achieving the positioning and lifting of the switch cover 7.

[0069] like Figure 5 and Figure 6 As shown, the cover clamping and feeding mechanism 303 mainly includes: a cover clamping bracket 308, a cover lateral moving component 309, a cover vertical moving component 310, and a clamping component 311; The cover lateral movement component 309 is horizontally mounted on the cover clamping bracket 308, the cover vertical movement component 310 is mounted on the cover lateral movement component 309, and the clamping component 311 is mounted on the cover vertical movement component 310. The clamping component 311 is moved horizontally by the cover lateral movement component 309 and the cover vertical movement component 310.

[0070] The cover lateral movement component 309 and the cover vertical movement component 310 can adopt a cylinder and guide rail combination structure or a motor screw drive structure. This is existing technology and will not be discussed in detail.

[0071] The main design features are in the clamping assembly 311, which includes a cylinder, a positioning shaft mounting plate, two positioning pins 312, and two cover clamping arms 313. The positioning shaft mounting plate is mounted on the vertical moving assembly 310 of the cover body. Two positioning pins 312 are vertically mounted on the positioning shaft mounting plate. A positioning protrusion protrudes from the lower end of the positioning pin 312. The positioning protrusion is adapted to the through hole 8. Two cover body clamping arms 313 are mounted on the clamping jaws of the cylinder. The middle part of the cover body clamping arm 313 expands outward and the lower end retracts inward. In normal operation, the clamping assembly 311 is positioned directly above the receiving groove. The ejection positioning mechanism 302 lifts the switch cover 7, causing the upper end of the lifted switch cover 7 to abut against the lower end face of the positioning post 312, and the positioning protrusion is inserted into the through hole 9. With the help of the ejection positioning mechanism 302, the lifted switch cover 7 can be positioned and fixed. Then, the cover clamping arm 313 clamps both sides of the switch cover 7 to achieve precise clamping and fixing of the switch cover 7. The cover is then moved above the placement seat 104 and placed on the placement seat 104. Due to the sufficiently precise clamping, the upper end of the rivet installed on the placement seat 104 passes through the through hole 9. Then, the pressing assembly 106 presses the positioning pressure plate 1053 onto the switch cover 7 to assemble the rivet on the switch cover 7. After that, the device returns to the initial position to perform the clamping operation of the next switch cover 7.

[0072] like Figure 7 As shown, the structure of the connector feeding device 400 is as follows: The connector feeding device 400 includes: a connector feeding mechanism 401, a material blocking and positioning mechanism 402, and a connector clamping and feeding mechanism 403; The connector feeding mechanism 401 uses a vibratory feeder; The material blocking and positioning mechanism 402 includes a second feeding bracket 404, on which a second positioning long groove 405 is provided. The connecting piece material handling mechanism 401 is connected to the second positioning long groove 405, so that the connecting piece enters the second positioning long groove 405. A third positioning component 406 and a fourth positioning component 407 are provided on the second feeding bracket 404.

[0073] Positioning component 3 406 includes a positioning fork plate and a cylinder. The positioning fork plate has a fork groove. The cylinder pushes the positioning fork plate to move at the end of the positioning long groove 2 405, which is used to push the connecting piece located at the end into the positioning long groove 2 405. Positioning component 407 is installed below positioning slot 2 405. It mainly includes positioning pin 408 and cylinder. The cylinder controls positioning pin 408 to extend into positioning slot 2 405 and into the hole of the connecting piece held by positioning fork plate.

[0074] The connecting piece is accurately fixed in the end of the positioning slot 2 405 by positioning component 3 406 and positioning component 407. Since the vibrating plate vibrates, this design can also avoid shaking and ensure accurate clamping.

[0075] The structure of the connecting piece clamping and feeding mechanism 403 is as follows: The connecting piece clamping and feeding mechanism 403 includes a connecting piece feeding slide 409, a connecting piece lateral movement assembly 410, a connecting piece vertical movement assembly 411, a connecting piece rotation assembly 412, and a connecting piece clamping assembly 413; The connecting piece feeding slide 409 is movably mounted on the second feeding bracket 404 via a guide rail slider structure and is driven to move by a cylinder; the connecting piece lateral moving assembly 410 is horizontally mounted on the upper end of the second feeding bracket 404 and is driven by a motor screw drive mechanism or a cylinder. The connecting piece lateral moving assembly 410 drives the connecting piece vertical moving assembly 411 to move laterally; the connecting piece vertical moving assembly 411 uses a cylinder or screw drive mechanism, and a connecting piece rotating assembly 412 is installed on its output end. The output end of the connecting piece rotating assembly 412 is connected to the connecting piece clamping assembly 413, which uses a pneumatic gripper.

[0076] The connecting plate rotating assembly 412 is mainly to meet the needs of installing connecting plates on both sides.

[0077] The connecting piece is installed onto the switch cover 7 on the placement base 104, that is, the connecting piece is installed onto the rivet, and the connecting piece is located in the notch 1056 of the positioning pressure plate 1053 to achieve accurate installation.

[0078] like Figure 8 As shown, the structure of the riveting device 500 is as follows: The riveting device 500 includes: a riveting bracket 501, a riveting die 502, and a lower support mechanism 503; The riveting bracket 501 is installed on the frame 3. A cylinder is installed on the riveting bracket 501. A riveting die 502 is installed at the output end of the cylinder. The cylinder controls the riveting die 502 to press down toward the placement seat 104, pressing against the upper end of the rivet on the placement seat 104. Then it continues to press down, deforming the rivet, so as to achieve the connection and fixation of the rivet, the switch cover 7 and the connecting piece.

[0079] Because riveting involves significant downward pressure, a lower support mechanism 503 is installed below the turntable 102 to prevent deformation of the turntable 102 or damage to other parts. This mechanism holds the lower end of the turntable 102 in place during riveting, thus preventing deformation and other problems.

[0080] The lower support mechanism 503 includes a guide seat 504, a support column 505, a pad 506, and a cylinder; The lower end of the support column 505 is vertically and movably placed inside the guide seat 504, and the pad 506 is horizontally and movably placed inside the guide seat 504. The output end of the cylinder is connected to the pad 506, which allows the pad 506 to move horizontally back and forth inside the guide seat 504. Since the upper end of the pad 506 is designed with a slope, the support column 505 can move up and down inside the guide seat 504 during the movement of the pad 506. When it extends, it presses against the lower end face of the turntable 102. When it retracts, the turntable 102 rotates normally.

[0081] To make the reset of the support column 505 more stable, two springs are installed outside the guide seat 504. The upper end of the spring pulls the support column 505, and the springs help the guide column return to its stable position.

[0082] The riveting device 500 is equipped with two sets, which rivet two rivets sequentially.

[0083] The above-mentioned devices can be used to install the connecting piece assembly on the switch cover 7, forming a semi-finished switch cover.

[0084] like Figure 9 and Figure 10 As shown, in order to transport the semi-finished switch cover to the bolt assembly equipment 1, a semi-finished product flipping and unloading device 600 is designed, the structure of which is as follows: The semi-finished product turning and discharging device 600 includes: a conveyor belt 610, a material transfer mechanism 602, a semi-finished product opening and closing cover feeding mechanism 603, and an unlocking mechanism 604; In order for the material transfer mechanism 602 to remove the semi-finished switch cover from the placement seat 104, the positioning pressure plate 1053 needs to be pushed upward away from the placement seat 104 first. Specifically, the unlocking mechanism 604 includes a cylinder and a buffer block. The cylinder is installed below the turntable 102, specifically below the semi-finished switch cover. The cylinder drives the buffer block to move upward, lifting the slide rail 1052, thereby causing the positioning pressure plate 1053 to move upward and disengage from the semi-finished switch cover.

[0085] The conveyor belt 610 is mounted on the frame 3 and located on one side of the turntable 102. The material transfer mechanism 602 is located on one side of the conveyor belt 610 and mainly includes: a transverse moving cylinder 605, a slide table 606, an up and down moving cylinder 607, a rotary swing cylinder 608, and a pneumatic gripper. The slide table 606 is slidably mounted on the frame 3. The transverse moving cylinder 605 pushes the slide table 606 to move. The vertical moving cylinder 607 is mounted on the slide table 606. The rotary swing cylinder 608 is connected and fixed to the output end of the vertical moving cylinder 607. The pneumatic gripper is connected to the rotary swing cylinder 608.

[0086] Specific actions: The lateral movement cylinder 605 pushes the slide table 606 toward the turntable 102, so that the pneumatic gripper clamps the semi-finished switch cover on the placement seat 104. Then, the up-down movement cylinder 607 first drives the pneumatic gripper to move upward, so that the semi-finished switch cover is disengaged from the positioning pin 1012. Then, the lateral movement cylinder 605 pulls back the slide table 606, and then the rotating swing cylinder 608 rotates, so that the semi-finished switch cover rotates 180 degrees and is placed above the conveyor belt 610. Then, the pneumatic gripper releases, and the semi-finished switch cover falls onto the conveyor belt 610 and is transported to the semi-finished switch cover loading mechanism 603. The semi-finished switch cover loading mechanism 603 clamps and transports it to the bolt assembly equipment 1 for reassembly.

[0087] The structure of the semi-finished switch cover feeding mechanism 603 is the same as that of the cover clamping feeding mechanism 303. Please refer to the above description for details, and we will not repeat them here.

[0088] The following describes the relevant structure of bolt assembly equipment 1: like Figure 10 As shown, the bolt assembly equipment 1 includes a frame 2 4, a rotating device 2 6, a gasket feeding device 700, a screw feeding device 800, a washer feeding and clamping device 900, and a detection device 11; The simplified process is as follows: Rotating device 2 6 first receives the semi-finished switch cover from the semi-finished switch cover feeding mechanism 603. Then, rotating device 2 6 transports the semi-finished switch cover to the gasket feeding device 700 for gasket assembly, then to the screw feeding device 800 for screw assembly, then to the washer feeding and pressing device 900 for washer assembly and pressing, then to the detection device 11 to check if the screw is installed, and finally to the finished product unloading device 12 to unload the qualified products.

[0089] Next, each device will be discussed in detail, starting with the rotating device 26; The structure of the rotating device 2 6 is basically the same as that of the rotating device 1 100. It mainly includes the driving mechanism 2 and the turntable 2. Several workstations are arranged on the circumference of the turntable 2. Tooling fixtures 2 are arranged on the workstations. The difference is that the rotating device 2 6 does not have the positioning mechanism 1 103, the sliding positioning mechanism 105 and the clamping assembly 106. The tooling fixture 2 is a placement seat 104. The placement seat 104 has been adapted to accommodate the different shapes of the end of the switch cover, which will not be described in detail.

[0090] The structure of the gasket feeding device 700 is as follows: The gasket feeding device 700 includes a bracket, a gasket sorting mechanism 701, a gasket lateral moving mechanism 702, and a gasket vertical moving mechanism 703; The gasket feeding mechanism 701 and the bracket are both mounted on the frame 4. The gasket feeding mechanism 701 is mainly used to sort, arrange and transport the gaskets. It uses a vibratory feeder. The gaskets are transported to the gasket placement position on the bracket. The gasket lateral movement mechanism 702 is mounted on the upper end of the bracket. The gasket vertical movement mechanism 703 is mounted on the gasket lateral movement mechanism 702. The gasket vertical movement mechanism 703 includes a cylinder and a suction nozzle. The cylinder drives the suction nozzle to move up and down to suck out the gaskets in the gasket placement position. Then, they are placed into the switch cover 7. Two gaskets are placed at a time.

[0091] The gasket lateral movement mechanism 702 uses a linear cylinder or motor screw mechanism to realize the horizontal movement of the gasket vertical movement mechanism 703.

[0092] like Figure 11 As shown, the structure of the screw feeding device 800 is as follows: The screw feeding device 800 includes a screw support 801, a screw material handling mechanism 802, and a screw lateral movement mechanism 803; The screw feeding mechanism 802 is installed on the second frame 4 and uses a vibratory feeder mechanism to feed the screw. The screw support 801 is installed on the second frame 4 and a screw receiving seat 804 is provided on the screw support 801. The screw receiving seat 804 has a screw feed groove 805 and a feeding groove 806. The screw feed groove 805 and the feeding groove 806 are perpendicular to each other. The screw feed groove 805 is connected to the vibratory feeder so that the screws fed by the vibratory feeder are neatly arranged and enter the screw feed groove 805. The screw support 801 is provided with a pusher assembly 3 807, which includes a pusher cylinder and a pusher seat 1 808. The pusher seat 1 808 is installed in the feeding groove 806 and its rear end is connected to the output end of the pusher cylinder. A slot that can accommodate a screw is opened in the pusher seat 1 808.

[0093] During operation, the vibratory feeder feeds the screw into the screw feed groove 805. At this time, the groove of the pusher seat 808 corresponds to the screw feed groove 805, and the foremost screw will enter the groove. Then, the pusher cylinder pushes the pusher seat 808 to move, and the screw in the groove will follow the pusher seat 808 to move, thereby moving the screw to a certain position for subsequent work. This avoids interference between screws.

[0094] The screw lateral movement mechanism 803 mainly includes: screw lateral movement assembly 809, screw vertical movement assembly 810, and pneumatic gripper and pressing assembly 811; The lateral movement assembly 809 uses a conventional ball screw drive mechanism, while the vertical movement assembly 810 uses a conventional cylinder and guide rail slider design. The pressing assembly 811 includes a cylinder and a pressing rod, the pressing rod being mounted on the output end of the cylinder.

[0095] The working action is as follows: the horizontal moving component and the vertical moving component move the pneumatic gripper to the slot of the pusher seat 808. The pneumatic gripper holds the screw in the slot. Then, the screw is moved to the placement seat 104 on the turntable 2, so that the screw is aligned with the through hole 8 of the switch cover 7. Then, the cylinder presses down the pressing rod to press the screw into the through hole 8. After the screw is pressed into place, the mechanism resets and repeats the above action. A total of two screws are installed, and then the next action can be performed.

[0096] like Figure 12-22 As shown, the structure of the washer feeding and clamping device 900 is as follows: Combination Figure 12 and Figure 13 The washer feeding and pressing device 900 includes a washer placement mechanism 901, a washer feeding mechanism 902, and a washer pressing mechanism 903. The three mechanisms are described below.

[0097] Figure 18 or Figure 21 or Figure 22 As shown, the washer placement mechanism 901 includes a mounting bracket 904, a mounting base 905, and a balancing component 906. The balancing component 906 includes a balancing block 907, a press-in sleeve 908, and a positioning shaft 909, etc. A groove is made on the mounting bracket 904, and the mounting seat 905 is partially placed in the groove. The mounting seat 905 can slide up and down along the groove. The structure of the mounting seat 905 in the groove can be a convex groove and a corresponding earth-shaped protrusion.

[0098] The balancing component 906 is installed within the mounting base 905. Specifically, a mounting cavity 910 is formed within the mounting base 905, and the balancing block 907 is placed within the mounting cavity 910. A pin is provided in the middle of the mounting cavity 910, passing through the middle of the balancing block 907, thus fixing the balancing block 907 within the mounting cavity 910. The balancing block 907 can swing slightly around the pin. A balancing cavity is also formed within the mounting base 905. In this embodiment, two balancing cavities are formed, located above both ends of the balancing block 907. These balancing cavities are used to install the press-fit sleeve 908 and the positioning shaft 909. The press-fit sleeve 908 and the positioning shaft 909 installed in both balancing cavities have the same structure; therefore, only one will be described. The positioning shaft 909 is installed within the press-fit sleeve 908. Inside the insert sleeve 908, the press-in sleeve 908 is installed in the balance cavity, and the lower end of the press-in sleeve 908 movably presses against one side of the balance block 907. A balance return spring 911 is installed in the balance cavity to ensure that the press-in sleeve 908 is always pressed against the balance block 907. A balance return spring 912 is installed inside the press-in sleeve 908. The balance return spring 912 supports the positioning shaft 909, allowing the upper end of the positioning shaft 909 to protrude from the upper end of the press-in sleeve 908. When the upper end of the positioning shaft 909 is pressed, the positioning shaft 909 can press the balance return spring 912, causing the upper end of the positioning shaft 909 to retract into the press-in sleeve 908. A threaded sleeve is installed at the lower end of the press-in sleeve 908 to support the balance return spring 912.

[0099] Meanwhile, a reset component 913 is provided on the mounting bracket 904, which is used to pull the mounting base 905 back to its initial position.

[0100] Furthermore, an arc-shaped abutment portion 914 protrudes upward from the counterweight 907 directly below the press-in sleeve 908. In this embodiment, the arc-shaped abutment portion 914 is hemispherical. After the arc-shaped abutment portion 914 presses against the counterweight 907, if the pressure on the two press-in sleeves 908 is different, the pressure on the two press-in sleeves 908 can be adjusted by the counterweight 907, or the upper end faces of the press-in sleeves 908 can be made to be as close to the same plane as possible. This ensures that the installed gaskets are in a horizontal and consistent position, guaranteeing the pass rate of subsequent products. The arc-shaped abutment portion 914 can minimize the impact on adjusting the horizontality of the upper end face of the press-in sleeve 908.

[0101] [Modified Example] The arc-shaped abutment part 914 can also be protruding and formed on the balance block 907. In this case, the arc-shaped abutment part 914 is in the form of a convex strip. The convex strip is set parallel to the pin shaft. The side wall of the convex strip is arc-shaped, and it is set on the balance block 907 in an approximate half cylinder cut from the axis.

[0102] An obstacle clearance hole 915 is provided on the balance block 907. The obstacle clearance hole 915 is mainly to allow space for the positioning shaft 909 when the positioning shaft 909 is pressed down, so as to realize the action of the positioning shaft 909 retracting and pressing into the sleeve 908.

[0103] The lower end face of the balance block 907 is higher than the lower end face of the mounting base 905, so that the lower end face of the balance block 907 is not blocked, allowing the balance block 907 to swing and achieve balance adjustment.

[0104] Combination Figures 13-16 The structure of the washer feeding mechanism 902 is as follows: The washer feeding mechanism 902 includes a washer feeding bracket 916, a washer first material handling mechanism 917, a washer first feeding mechanism 919, a washer second material handling mechanism 918, a washer second feeding mechanism 920, a washer horizontal moving mechanism 921, and a washer first material picking mechanism 922. The switch cover is secured using two different washers, so two sets of devices are needed for feeding.

[0105] Both the gasket feeding mechanism 917 and the gasket feeding mechanism 918 use commercially available vibratory feeder mechanisms to feed gasket 1 and gasket 2 respectively. Since the gasket feeding mechanism 919 and the gasket feeding mechanism 920 have the same structure, the gasket feeding mechanism 919 will be used as an example for further explanation.

[0106] like Figures 14-16 The washer feeding mechanism 919 includes: a feeding seat 923, a feeding sliding strip 924, a feeding cylinder 925, and a washer positioning mechanism 926. The feeding seat 923 is fixed on the washer feeding bracket 916. A sliding cavity 927 is provided on the feeding seat 923. The feeding sliding strip 924 is slidably placed in the sliding cavity 927. That is, sliding strips are provided on both sides of the feeding sliding strip 924. Sliding grooves are recessed in both sides of the sliding cavity 927. The sliding strips are placed in the sliding grooves. On the one hand, the feeding sliding strip 924 is constrained to prevent it from falling out of the sliding cavity 927. On the other hand, it ensures the stability of the movement of the feeding sliding strip 924. The lower end face of the feeding sliding bar 924 has space between it and the bottom of the sliding cavity 927. The washer positioning mechanism 926 is installed on the feeding seat 923 and extends into the sliding cavity 927. The feeding sliding bar 924 is provided with a feeding positioning groove 928, and part of the washer positioning mechanism 926 can extend into the feeding positioning groove 928. The washer sorting mechanism 917 is connected to the side of the feeding seat 923 and conveys the sorted washer to the feeding positioning groove 928 in the feeding seat 923.

[0107] The working action is as follows: after washer one enters the feeding positioning groove 928, the end of the washer one positioning mechanism 926 moves upward, extends into the feeding positioning groove 928, and passes through washer one, fixing washer one in the feeding positioning groove 928. Then, the feeding cylinder 925 pushes the feeding sliding bar 924 forward. At this time, the part of the washer one positioning mechanism 926 that extends into the feeding sliding bar 924 separates out and moves forward with the feeding sliding bar 924. The separated part slides within the space between the lower end face of the feeding sliding bar 924 and the bottom of the sliding cavity 927, so that the feeding sliding bar 924 is always in a fixed and positioned state during the forward movement until it moves to the front end of the sliding cavity 927. This achieves the positioning and feeding of a single washer one.

[0108] During the movement of the feeding slide bar 924, due to inertia or the jerking sensation caused by the feeding cylinder 925 driving the feeding slide bar 924, the first washer may shift or lift in the feeding positioning groove 928. This will affect the clamping of the subsequent first washer picking mechanism 922. If a clamping deviation occurs, the first washer will not be accurately fitted onto the screw, resulting in assembly failure.

[0109] This technical solution constrains washer one by using the groove wall of the feeding positioning groove 928 and the groove wall of the sliding cavity 927, and combined with the washer one positioning mechanism 926, it can ensure the stability of washer one during the movement process.

[0110] The washer positioning mechanism 926 includes an ejector cylinder 929, a connecting seat 930, and a positioning pin 931; The ejector cylinder 929 is vertically installed below the loading seat 923. The connecting seat 930 is connected to the output end of the ejector cylinder 929 and is located in the slot of the loading seat 923. Its upper end extends into the sliding cavity 927. A U-shaped connecting groove is recessed downward at the upper end of the connecting seat 930. The U-shaped connecting groove runs through the front and rear ends of the connecting seat 930, so that the side wall of the U-shaped connecting groove is connected to the movable cavity. The lower side wall of the positioning pin 931 has an annular groove. The positioning pin 931 can be engaged in the U-shaped connecting groove through the annular groove, and can also move laterally out of the annular groove. The upper end of the positioning pin 931 is a protruding post. The diameter of the protruding post is adapted to the inner diameter of the washer.

[0111] In normal conditions, the positioning pin 931 does not extend into the feeding positioning groove 928. When the washer enters the feeding positioning groove 928, the ejector cylinder 929 operates vertically, causing the protruding post of the positioning pin 931 to extend into the feeding positioning groove 928 and pass through the washer. Then, the feeding cylinder 925 pushes the feeding sliding bar 924 forward. Since the side wall of the U-shaped connecting groove is connected to the sliding cavity 927, the positioning pin 931 can disengage and move with the feeding sliding bar 924, thus ensuring that the washer is always in a fixed positioning state during the movement.

[0112] like Figure 13 and Figure 19 As shown, the structure of the washer horizontal moving mechanism 921 is as follows: The washer horizontal moving mechanism 921 includes a washer lateral moving component 932, a washer vertical moving component 933, a washer front-to-back moving component 934, and a clamping component 935. The lateral movement assembly 932 of the washer can be designed using a conventional linear guide rail, or it can be set as in this embodiment with a lateral rail, on which two washer slides are installed. A cylinder is used to drive the two washer slides to move together, or two cylinders drive the washer slides to move laterally separately.

[0113] Each of the two washer slides is equipped with a set of washer up-and-down moving components 933. The two sets of washer up-and-down moving components 933 have the same structure and both use cylinders. A fixed seat is connected to the output end of the cylinder, and the cylinder drives the fixed seat to move up and down. The washer front-and-back moving component 934 also uses the form of a cylinder plus a fixed seat. The washer front-and-back moving component 934 is horizontally installed on the fixed seat of the washer up-and-down moving component 933, and the clamping member 935 is vertically fixed on the fixed seat of the washer front-and-back moving component 934.

[0114] By cooperating among several components within the gasket horizontal moving mechanism 921, the two types of gaskets, after being transported to their positions, can be clamped and fitted onto the aforementioned positioning shaft 909 and abut against the upper end face of the press-in sleeve 908. The two types of gaskets are placed in the following order: gasket one is below, and gasket two is above, and they are stacked on the upper end of the positioning shaft 909.

[0115] The aforementioned clamping component 935 comes in two forms: one uses a pneumatic gripper design to hold the washer, and the other uses a suction nozzle. A protruding post protrudes from the lower end of the suction nozzle, which can pass through the washer. The diameter of the protruding post is smaller than the diameter of the suction nozzle. An air intake is opened at the end of the suction nozzle outside the protruding post. When the protruding post is inserted into the washer, the washer can be adsorbed onto the end of the suction nozzle, thereby achieving the positioning and adsorption of the washer on the suction nozzle.

[0116] Since one of the gaskets is truncated cone-shaped with an inclined outer wall, in order to achieve adsorption of this type of gasket, it is necessary to design a tapered groove on the outside of the protrusion, so that the inclined outer wall can fit against the inner side of the tapered groove, and the air inlet is opened on the inner side wall of the tapered groove, thus achieving adsorption.

[0117] The structure of the washer clamping mechanism 903 is as follows: like Figure 17 and Figure 20As shown, the washer clamping mechanism 903 includes a clamping frame 936, and a support base 937 is provided at the lower end of the clamping frame 936. The mounting frame 904 is movably mounted on the support base 937 through a guide rail and a slider structure. A reciprocating drive component is also installed on the outside of the support base 937 to drive the mounting frame 904 to reciprocate on the support base 937. A clamping drive 939 is provided below the clamping frame 936. A clamping column 940 is installed at the output end of the clamping drive 939. The upper end of the clamping column 940 is fixed to the support base 937 by a bushing. The upper end of the clamping column 940 can pass through the support base 937 to move upward and press against the mounting base 905, so that the mounting base 905 moves upward against the reset member 913.

[0118] A second pressing assembly 941 is installed on the upper end of the pressing frame 936. The second pressing assembly 941 includes a pressing seat 942, which is fixed to the upper end of the pressing frame 936. A vertical cylindrical cavity is opened inside the cavity. The opposite side walls of the cylindrical cavity are provided with movable grooves 943. A pressing column 944 is movably arranged in the cylindrical cavity. A mounting shaft 945 is provided on the upper end of the pressing column 944. A bearing 946 is provided in the middle of the mounting shaft 945. The two ends of the mounting shaft 945 respectively pass through corresponding movable parts. A tension spring 947 is provided at the upper end of the clamping frame 936 in the groove 943. The lower end of the tension spring 947 is connected to the end of the mounting shaft 945 that passes through the movable groove 943, so that the lower pressure column 944 has an upward tendency. A track seat 948 is provided at the upper end of the lower pressure seat 942. A track moving plate 949 is provided in the track seat 948. The track moving plate 949 is reciprocated on the track moving plate 949 by the clamping cylinder 950 provided on the clamping frame 936.

[0119] The lower end of the track moving plate 949 is provided with a track surface 951, which is inclined. The upper bearing 946 of the mounting shaft 945 can be tightly attached to the track surface 951 by tension spring 947.

[0120] Combination Figure 12 When the track moving plate 949 moves, the inclined track surface 951 causes the lower pressing column 944 to move downward against the tension spring 947, so that the lower end of the lower pressing column 944 extends out of the lower pressing seat 942 and abuts against the bolt end of the semi-finished switch cover on the turntable 2 directly below the lower pressing seat 942.

[0121] like Figure 20-22As shown, at this time, the clamping drive 939 moves the mounting base 905 upward along the slide groove through the clamping column 940. When the upper end of the positioning shaft 909 abuts against the lower end face of the bolt inside the switch cover, the positioning shaft 909 cannot continue to move upward. At this time, the balance reset spring 912 is compressed, and the positioning shaft 909 retracts into the press-in sleeve 908. Since the inner diameter of the press-in sleeve 908 is larger than the lower end diameter of the screw, the end of the screw can extend into the press-in sleeve 908. Since the washer is larger than the inner diameter of the press-in sleeve 908, the washer is pushed upward. The washer is fitted onto the screw. When the washer is pushed to the end face abutting against the end face of the switch cover 7, the press-in sleeve 908 continues to move upward, causing the washer to deform and the taper to change. At this time, the washer can be locked onto the screw, thus completing the fixed assembly of the washer and screw. After that, the device is reset, and the above actions can be continued for the next assembly of the washer.

[0122] The design of the clamping column 940 and related structures can hold the screw in place, preventing the screw from moving upwards during the process of fixing the washer to the screw, which could lead to incorrect assembly position.

[0123] During the clamping process, the design of the balancing component 906 ensures that the clamping force of washer one and washer two is the same. If the forces are different, they will be adjusted by the balancing block 907, further ensuring the accuracy of the assembly.

[0124] The testing device 11 is mainly used to detect whether the assembled switch cover has a screw, so as to ensure the pass rate of the next product.

[0125] The detection device 11 includes a bracket for fixing, a cylinder is installed at the upper end of the bracket, and two contact displacement sensors are installed at the output point of the cylinder. The contact displacement sensors are located above the placement seat 104 of the turntable, and the cylinder can move the contact displacement sensors toward the placement seat 104.

[0126] When there is a mounting screw inside the switch cover, the contact displacement sensor will be blocked and thus triggered. If there is no screw, it will not be triggered, indicating that the product is defective.

[0127] The function of the finished product unloading device 12 is to unload the products after they have been inspected by the inspection device 11, and to classify the qualified and unqualified products for subsequent unified processing.

[0128] The finished product unloading device 12 includes an unloading conveyor belt and a finished product unloading mechanism. The finished product unloading mechanism clamps the switch cover from the turntable 2 and flips it to place it on the unloading conveyor belt. The unloading conveyor belt transports the product to the set position.

[0129] The finished product unloading mechanism includes a horizontally arranged linear guide rail, a cylinder vertically mounted on the linear guide rail, a short-stroke cylinder vertically mounted on the output piston of the cylinder, and a rotating gripper horizontally fixed to the piston end of the short-stroke cylinder.

[0130] The unloading process involves the finished product unloading mechanism first moving the rotating gripper to the assembled switch cover and clamping it. Then, the short-stroke cylinder works first to clamp the switch cover upward away from the placement seat 104. After that, it continues to rise, and the linear guide rail moves the rotating gripper horizontally. During the movement, the rotating gripper rotates the clamped switch cover so that its front side faces upward, that is, the side with the boss faces upward, and places it on the unloading conveyor belt to complete the unloading of the product.
