Description

Technical Field

[0001] This invention relates to the field of circuit breaker assembly equipment technology, and more specifically to an automatic assembly device for circuit breaker clips. Background Technology

[0002] Miniature circuit breakers are basic low-voltage electrical appliances with overload, short-circuit, and undervoltage protection functions, capable of protecting lines and power supplies. Currently, circuit breaker assembly is still in the stage of manual or semi-automatic assembly. For example, the assembly of the clips (stops), which are generally located at the bottom of the circuit breaker and used to secure it to the guide rail, involves placing the clips flat on the bottom of the circuit breaker and then pushing them into the engaging slots at the bottom of the circuit breaker. Manual assembly has inconsistent pass rates and low efficiency. Semi-automatic equipment is more efficient and has a higher pass rate than manual assembly, but it is not suitable for mass production.

[0003] To meet the demands of production automation, researchers have begun to study automatic assembly devices for circuit breaker clips. For example, Chinese invention patent CN111477485A discloses an automatic assembly device for circuit breaker clips that achieves fully automated assembly of the stop and the circuit breaker, replacing manual operation, significantly improving work efficiency, and conforming to the assembly method of large-scale production lines. However, this equipment lacks the ability to detect and distinguish between qualified and unqualified products, still requiring manual inspection.

Implementation

[0030] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0031] Taking the mounting clips of a 5P circuit breaker as an example, a 5P circuit breaker generally has clips installed at both ends and in the middle of the bottom of the circuit breaker, meaning each circuit breaker requires three clips. Figure 1-2As shown, an automatic assembly device for circuit breaker clips includes a frame 1, on which a turntable 2 driven by a turntable drive mechanism is provided. The turntable 2 has 8 workstations, and each workstation is provided with a turntable clamp 3. Along the rotation direction of the turntable, the frame 1 is provided with a double clip feeding assembly 4, a clip detection assembly 5, a single clip feeding assembly 10, a circuit breaker feeding assembly 6, a clip installation assembly 7, a vision inspection assembly 8, and a finished product discharge assembly 9 in sequence corresponding to each workstation. When assembling circuit breakers of 4P and below, only the clips need to be installed at both ends of the bottom of the circuit breaker, so the single clip feeding assembly 10 can be omitted or does not need to be started.

[0032] The assembly process of this device is as follows: First, the clip feeding assembly feeds the clip material to the turntable clamp 3. The clip detection assembly 5 detects the clips on the turntable clamp 3. Second, the circuit breaker feeding assembly 6 feeds the circuit breaker material to the turntable clamp 3 and places it above the clip material. The clip installation assembly 7 installs the clip material to the bottom of the circuit breaker to form the finished product. The vision inspection assembly 8 detects the finished product after installation. Finally, the finished product discharge assembly 9 discharges the finished products that have been detected by the vision inspection assembly 8 into qualified and unqualified products.

[0033] This device adopts a rotary structure, enabling a cyclical processing flow. The equipment occupies a small area, which helps enterprises save production costs and meets the needs of large-scale automated production. By setting a snap-fit ​​detection component between the snap-fit ​​feeding component and the circuit breaker feeding component to detect the snap-fit ​​position, the yield rate is improved. A vision inspection component is set between the snap-fit ​​installation component and the finished product discharge component to distinguish between qualified and unqualified products, realizing fully automated assembly and inspection.

[0034] like Figure 3 As shown, the turntable drive mechanism includes a first servo motor 22. The output end of the first servo motor 22 is provided with a drive wheel 23. The drive wheel 23 is linked to the cam divider 25 through a synchronous belt 24. The output shaft of the cam divider 25 is provided with a dividing code disk 26. The side of the dividing code disk 26 is provided with a proximity switch 27. The turntable 2 is linked with the cam divider 25. The rotation of the first servo motor 22 will drive the turntable 2 to rotate. Every time the turntable 2 rotates by a certain angle, it will drive the dividing code disk 26 to rotate by a certain angle. The dividing code disk 26 is provided with a trigger end. When the trigger end is close to or away from the proximity switch 27, it will control the switch to open or close, thereby controlling the opening and closing of the first servo motor 22.

[0035] like Figure 4-5As shown, the turntable clamp 3 includes a connecting part 31 and a feeding part 32. The connecting part 31 is used to connect with the turntable 2. The feeding part 32 is provided with a front stop 34 and a rear stop 35 at its front and rear ends, respectively. The feeding part has 5 feeding slots 36, and the number of feeding slots can be increased or decreased as needed. Each feeding slot 36 is provided with a support member 37 for supporting the buckle 101. A positioning protrusion 33 is provided between the feeding slots 36. The positioning protrusion 33, the front stop 34, and the rear stop 35 cooperate to position and fix the circuit breaker, preventing the circuit breaker from detaching from the turntable clamp 3 when assembling the buckle. Furthermore, the feeding part 32 is provided with a rotating shaft 38, and the support member 37 is sleeved on it. The support member 37 is divided into a pressing part 371 and a lever part 373 by the rotating shaft 38 and can be used as a fulcrum for lever movement. The rotating shaft 38 provides a first limiting groove 372. The rotating shaft 38 is provided with a torsion spring 39 for resetting the support member 37. The torsion arm of the torsion spring 39 is limited in the first limiting groove 372. Under normal conditions, the lever part 373 of the support member 37 contacts the side wall of the discharge groove 36 under the pressure of the torsion spring 39 to prevent the buckle from falling off. When the pressing part 371 is pressed by an external force, the lever part 373 moves downward and separates from the side wall of the discharge groove 36, opening a channel for the buckle to fall off.

[0036] like Figure 6-7 As shown, taking the double-clamp feeding assembly 4 as an example, the structure of the single-clamp feeding assembly 10 is the same as that of the double-clamp feeding assembly 4, except for the number of material channels, and will not be described again. The double-clamp feeding assembly 4 includes a vibratory feeding mechanism and a clamping transport mechanism 44.

[0037] The vibrating feeding mechanism is arranged in sequence according to the direction of the buckle movement: a hopper 41, a vibrating plate 43, a feed channel 441, and a feeding section 444. A first vibrator 42 is located below the hopper 41. The hopper 41 is funnel-shaped. When the buckle material is poured into the hopper 41, the vibration of the first vibrator 42 will send the buckles in the hopper 41 to the vibrating plate 43. The vibration of the vibrating plate 43 will send the buckles one by one to the feed channel 441. The feed channel 441 has baffles 451 on both sides to prevent the buckles from falling out, and a retainer at the top to prevent the buckles from popping up. Part 452, a second vibrator 443 is provided below the material channel 441. The vibration of the second vibrator 443 sends the buckle 101 on the material channel 441 to the feeding part 444. A first lifting cylinder 445 is provided below the feeding part 444 to drive the feeding part 444 to move up and down. In order to facilitate automatic control, a first fiber optic probe 442 is provided at the front end of the material channel 441 to detect whether there is a buckle on the material channel 441. A second fiber optic probe 453 is provided at the feeding part 444 to detect whether there is a buckle on the feeding part 444.

[0038] The latching and handling mechanism 44 includes a latching gripper 446, a first drive cylinder 447 for driving the latching gripper 446 to clamp or release, a first gripper slider 448 above the latching gripper 446, a second drive cylinder 449 for driving the first gripper slider 448 to move in the X-axis direction, and a third drive cylinder 450 for driving the first gripper slider 448 to move in the Y-axis direction. Furthermore, a spring seat 454 is provided on the first gripper slider 448, and a spring shaft 455 is provided on the spring seat 454. The spring shaft 455 is correspondingly arranged with the latching gripper 446. The latching gripper 446 grasps the front end of the latch 101, and the spring shaft 455 presses against the rear end of the latch 101 to ensure stable gripping. After the vibrating feeding mechanism delivers the buckle 101 to the feeding section 444, the first lifting cylinder 445 drives the feeding section 444 to move upward, the first driving cylinder 447 drives the buckle gripper 446 to clamp the buckle 101, the second driving cylinder 449 and the third driving cylinder 450 drive the first gripper slider 448 to move above the turntable clamp 3 of the turntable 2, and the first driving cylinder 447 drives the buckle gripper 446 to release the buckle 101 to complete the feeding.

[0039] like Figure 8 As shown, the buckle detection component 5 includes a detection bracket 51, a detection fiber block 52 on the detection bracket 51, and a third fiber probe 53 on the detection fiber block 52. The third fiber probe 53 is located above the turntable clamp 3 and corresponds to the feeding trough. It can detect whether there is a buckle in each feeding trough and can be electrically connected to the upper electromechanical unit to provide real-time alarm or start / stop the equipment to prevent the equipment from running under no-load.

[0040] like Figure 9 As shown, the circuit breaker feeding assembly 6 includes a feeding conveyor belt 61 and a circuit breaker gripping and handling mechanism. Guardrails 62 are provided on both sides of the feeding conveyor belt 61. The width of the guardrails 62 is adapted to the width of the circuit breaker 102 to ensure stable conveying of the circuit breaker 102. The circuit breaker gripping and handling mechanism includes a feeding gripper 63 and a fourth drive cylinder 64 for driving the feeding gripper 63 to clamp or release. A first gripper mounting plate 65 is provided on the feeding gripper 63. A first swing cylinder 66 for driving the first gripper mounting plate 65 to swing laterally and a fifth drive cylinder 67 for driving the first gripper mounting plate 65 to move laterally are provided on the first gripper mounting plate 65.

[0041] like Figure 10As shown, the snap-fit ​​mounting assembly 7 includes an upper limit mechanism 71 and a lower mounting mechanism 72. The upper limit mechanism 71 is located above the turntable clamp 3 and includes a clamping block 73 and a sixth drive cylinder 74 for driving the clamping block 73 to move up and down. The lower mounting mechanism 72 includes a push block seat 75 and a seventh drive cylinder 77 for driving the push block seat 75 to move back and forth. The push block seat 75 is provided with several levers 76. When assembling the snap-fit, firstly, the sixth drive cylinder 74 drives the clamping block 73 to move down and clamp the circuit breaker. The seventh drive cylinder 77 drives the push block seat 75 to move forward, causing the levers 76 to move the snap-fit ​​forward and engage with the engagement part at the bottom of the circuit breaker to complete the assembly. The upper limit mechanism 71 can ensure that the circuit breaker will not shift during the assembly process, making the assembly position accurate and improving the product qualification rate.

[0042] like Figure 11 As shown, the visual inspection component 8 includes a column 81, on which an upper radial support 82 and a lower radial support 85 are mounted. A camera 83 is mounted on the upper radial support 82, and a ring light source 84 is mounted on the lower radial support. The center points of the camera 83 and the ring light source 84 are coaxially arranged. The ring light source 84 provides good lighting to ensure the efficiency of visual inspection. The visual inspection component 8 can be electrically connected to a host computer to detect and output a signal indicating whether the inspected product is qualified in real time.

[0043] like Figure 12 As shown, the finished product discharge assembly 9 includes a qualified product discharge belt 91, a non-qualified product discharge belt 92, a qualified product gripping and conveying mechanism 93, a non-qualified product gripping and conveying mechanism 94, and a non-qualified product lifting mechanism. The qualified product gripping and conveying mechanism 93 and the non-qualified product gripping and conveying mechanism 94 have the same structure, both including a discharge gripper 95 and an eighth drive cylinder for driving the discharge gripper 95 to clamp or release. The discharge gripper 95 is provided with a second gripper mounting plate, and the second gripper mounting plate is provided with a second swing cylinder 96 for driving the second gripper mounting plate to swing laterally and a ninth drive cylinder 97 for driving the second gripper mounting plate to move laterally. The non-qualified product lifting mechanism includes a cam assembly 981 and a second lifting cylinder 981 for driving the cam assembly 981 to move up and down. 8. The finished product discharge assembly 9 is also equipped with a host computer. This host computer can receive the signal from the vision inspection assembly 8 indicating whether the product is qualified after inspection and determine whether to start the qualified product gripping and handling mechanism 93 or the unqualified product gripping and handling mechanism 94. When the signal from the vision inspection assembly 8 indicates whether the product is qualified after inspection is unqualified, the host computer outputs a signal to start the second lifting cylinder 98 to drive the cam assembly 981 to move upward and press the pressing part 371 of the support of the turntable clamp 3, and make the lever part 373 move downward and separate from the side wall of the discharge trough 36, opening a channel for the buckles to fall. The buckles fall downward through this channel. A buckle recovery box 99 can be set on the path of the buckles to recover the buckles, so that there are no residual buckles on the turntable clamp 3, ensuring the assembly process is cyclical.

[0044] The embodiments should not be construed as limiting the present invention, and any non-creative improvements made based on the spirit of the present invention should be considered within the scope of protection of the present invention.
