Description

Technical Field

[0001] This utility model relates to the field of circuit breaker manufacturing technology, and in particular to a lifting device and circuit breaker manufacturing equipment. Background Technology

[0002] The circuit breaker manufacturing equipment includes a lifting device and a conveying device for transporting the circuit breakers. The conveying device transports the circuit breakers to a preset position. The lifting device can lift the circuit breakers placed in the preset position on the conveying device upwards, separating the circuit breakers from the conveying device. A gripping mechanism can then grip the circuit breakers on the lifting device and place them into the testing or processing device of the next process. In the prior art, the lifting device does not have a positioning structure for positioning the circuit breakers. When lifting thin 1-pole circuit breakers, the circuit breakers are prone to tipping over, resulting in significant positional deviations and affecting the gripping mechanism's ability to grasp them. For circuit breakers with internal magnets, when the lifting device lifts multiple circuit breakers simultaneously, the repulsion between the circuit breakers due to the magnets can cause them to tip over, resulting in positional deviations and affecting the gripping mechanism's ability to grasp them.

[0039] like Figures 1 to 3 As shown, this embodiment provides a circuit breaker production equipment, which includes a conveying device 200 and a lifting device. The conveying device 200 is used to convey the circuit breaker 100 to the location where the lifting device is set. The lifting device lifts the circuit breaker 100 on the conveying device 200 upward, so that the circuit breaker 100 is separated from the conveying device 200. The circuit breaker 100 is taken away from the lifting device by a gripping device and transferred to the next processing station. Alternatively, a processing device or a testing device can be set at the location where the lifting device is set. The lifting device lifts the circuit breaker 100 on the conveying device 200 upward to the processing device or the testing device, so that the processing device processes the circuit breaker 100 or the testing device tests the circuit breaker 100.

[0040] like Figures 2 to 5 As shown, the lifting device includes a lifting assembly 1 and a lifting drive assembly 2. The lifting assembly 1 includes a lifting member 11 and two side positioning units 12. Each side positioning unit 12 includes a positioning side 121 and a positioning bottom 122. The positioning side 121 and the positioning bottom 122 are connected at an angle. The positioning bottom 122 is connected to the lifting member 11. The two positioning bottoms 122 are spaced apart and placed between the two positioning sides 121. The space between the two positioning bottoms 122 is used to accommodate the conveying device 200. Each positioning bottom 122 has a stop 13 at both ends. The first end of the stop 13 is set higher than the positioning bottom 122 in a first direction. The lifting drive assembly 2 is used to drive the lifting member 11 to descend along the first direction, so that the stop portion 13 is lower than the conveying device 200, or the lifting drive assembly 2 is used to drive the lifting member 11 to rise along the first direction, so that the positioning bottom 122 is higher than the conveying device 200, and the two positioning bottoms 122 are used to support the circuit breaker 100, the two stop portions 13 are used to limit the circuit breaker 100 along the thickness direction of the circuit breaker 100, and the two positioning sides 121 are used to limit the circuit breaker 100 along the length direction of the circuit breaker 100.

[0041] The conveying device 200 is disposed between the two positioning bottoms 122. The conveying device 200 is used to convey the circuit breaker 100 between the two positioning sides 121. When the lifting drive assembly 2 drives the lifting member 11 to descend in the first direction, the stop portion 13 is lower than the conveying device 200, thus providing a clearance. The conveying device 200 can convey the circuit breaker 100 to the position where the lifting device is located, that is, the circuit breaker 100 is placed between the two positioning sides 121. The width of the conveying device 200 is less than the length of the circuit breaker 100. When the lifting drive assembly 2 drives the lifting member 11 to rise in the first direction, the positioning bottoms 122... 22. Lift the circuit breaker 100 upwards to separate the circuit breaker 100 from the conveying device 200. Along the thickness direction of the circuit breaker 100, two stop parts 13 limit the circuit breaker 100 to prevent it from tipping over and to confine it between the two stop parts 13. Along the length direction of the circuit breaker 100, two positioning sides 121 limit the circuit breaker 100 to prevent it from falling. The two stop parts 13 and the two positioning sides 121 work together to adjust the position of the circuit breaker 100 placed on the positioning bottom 122, improving the accuracy of grabbing the circuit breaker 100 on the lifting device.

[0042] The conveying device 200 transports multiple circuit breakers 100 at a time and places them between two positioning sides 121, so that multiple circuit breakers 100 are positioned between two stop parts 13. Along the direction in which the conveying device 200 transports the circuit breakers 100, a stop 300 is provided downstream of the lifting device. The stop 300 is used to position the circuit breakers 100 transported by the conveying device 200 between the two positioning sides 121, allowing the conveying device 200 to operate without stopping, facilitating the lifting device to lift the circuit breakers 100 upwards. Optionally, the stop 300 has a plate-like structure, which is simple in structure. The conveying device 200 includes chain conveyors or belt conveyors, etc., and is not specifically limited here.

[0043] In some embodiments, the lifting drive assembly 2 includes a mounting plate 21 and a lifting drive component 22. The mounting plate 21 is connected to the conveying device 200. The lifting drive component 22 and the lifting component 11 are disposed on both sides of the mounting plate 21, with the lifting component 11 positioned below the conveying device 200. The lifting drive component 22 is fixed to the mounting plate 21. The driving end of the lifting drive component 22 passes through the mounting plate 21 and is connected to the lifting component 11. The lifting drive component 22 drives the lifting component 11 to descend or ascend in a first direction, thereby causing the side positioning unit 12 to descend or ascend, so that the stop portion 13 is lower than the conveying device 200, or the positioning bottom 122 is higher than the conveying device 200. The lifting drive component 22 can be a cylinder or a linear motor.

[0044] Optionally, a guide unit 23 connects the lifting component 11 to the mounting plate 21. The guide unit 23 includes multiple guide bearings 231 and multiple guide rods 232. The guide rods 232 are arranged in a one-to-one correspondence with the guide bearings 231. The guide bearings 231 are fixedly mounted on the mounting plate 21. One end of the guide rod 232 is fixedly connected to the lifting component 11, and the other end of the guide rod 232 is slidably connected to the guide bearing 231. The lifting drive component 22 is connected to the lifting component 11 through a floating joint 24 to prevent jamming when driving the lifting component 11 to rise or fall.

[0045] In some embodiments, such as Figure 5 and Figure 6 As shown, multiple connecting units 15 are provided between the lifting component 11 and each positioning bottom 122. Each connecting unit 15 includes a lifting rod 151 and an adjusting rod 152. One end of the lifting rod 151 is fixedly connected to the lifting component 11, and the other end of the lifting rod 151 is threaded. One end of the adjusting rod 152 is screwed to the other end of the lifting rod 151, and the other end of the adjusting rod 152 is rotatably connected to the positioning bottom 122. Rotating the adjusting rod 152 causes it to rotate relative to the lifting rod 151 and rise or fall along the thread of the lifting rod 151, thereby adjusting the lifting height of the lifting device to adapt the height of the circuit breaker 100 to production requirements.

[0046] Optionally, an adjusting nut 153 is connected to one end of the adjusting rod 152. The adjusting nut 153 and the adjusting rod 152 are both sleeved on the other end of the lifting rod 151. The adjusting nut 153 is threadedly connected to the lifting rod 151. Rotating the adjusting nut 153 can raise or lower the adjusting rod 152 relative to the lifting rod 151.

[0047] A connecting plate 16 is provided between the positioning bottom 122 and the lifting member 11. The connecting plate 16 is rotatably connected to the adjusting rod 152. The connecting plate 16 is provided with an oblong hole. The connecting plate 16 is connected to the positioning bottom 122 through the oblong hole. The oblong hole extends along the length direction of the circuit breaker 100, which can adjust the position of the positioning bottom 122 relative to the connecting plate 16. In this way, the distance between the two positioning sides 121 can be adjusted according to the length of the circuit breaker 100.

[0048] In another feasible embodiment, multiple connecting units 15 are provided between the lifting member 11 and each positioning base 122. Each connecting unit 15 includes a lifting rod 151 and an adjusting rod 152. One end of the lifting rod 151 is rotatably connected to the lifting member 11, and the other end of the lifting rod 151 is threaded. One end of the adjusting rod 152 is screwed to the other end of the lifting rod 151, and the other end of the adjusting rod 152 is fixedly connected to the positioning base 122. Rotating the lifting rod 151 causes the adjusting rod 152 to rise or fall relative to the lifting rod 151, thereby adjusting the lifting height of the lifting device to adapt the height of the circuit breaker 100 to production requirements.

[0049] In some embodiments, such as Figure 5 and Figure 7 As shown, the stop portion 13 has an adjusting ramp 131 and a stop surface 132 on the side facing the positioning bottom 122. The adjusting ramp 131 and the stop surface 132 are arranged sequentially from the first end to the second end of the stop portion 13, and the adjusting ramp 131 is inclined from the stop surface 132 toward the first end of the stop portion 13. The adjusting ramp 131 is configured to guide the circuit breaker 100 to fit against the stop surface 132. The adjusting ramp 131 can guide the circuit breaker 100 to be smoothly placed between the two stop portions 13, thus adjusting the position of the circuit breaker 100.

[0050] In some embodiments, guide members 14 are connected to both ends of the positioning side 121. The guide members 14 are flush with the side of the positioning side 121 facing the positioning bottom 122. The stop part 13 is connected to the positioning bottom 122. The upper end surface of the stop part 13 is lower than the upper end surface of the guide member 14. The guide member 14 is provided with a first guide slope 141, which extends from the upper end surface of the guide member 14 to the upper end surface of the stop part 13. When the stop part 13 is lower than the conveying device 200, the first guide slope 141 is positioned above the conveying device 200. The first guide slope 141 is configured to guide the circuit breaker 100 into the space between the two positioning sides 121. During the process of the circuit breaker 100 being conveyed into the space between the two positioning sides 121, the first guide slope 141 plays a role in adjusting the position of the circuit breaker 100 in the length direction of the circuit breaker 100, ensuring that the circuit breaker 100 can smoothly enter the space between the two positioning sides 121. In addition, both ends of the positioning side 121 are provided with guide members 14 having a first guide slope 141, so that either end of the positioning side 121 can be used as an entrance for the circuit breaker 100 to enter between the two positioning sides 121, which improves the flexibility of the lifting device.

[0051] In some embodiments, such as Figure 4 , Figure 6 and Figure 8As shown, the positioning side 121 includes a first positioning side plate 1211, and the positioning bottom 122 includes a first positioning bottom plate 1221. The first positioning side plate 1211 and the first positioning bottom plate 1221 are connected at an angle. The first positioning bottom plate 1221 is connected to the lifting member 11. The two first positioning bottom plates 1221 are spaced apart and placed between the two first positioning side plates 1211. The space between the two first positioning bottom plates 1221 is used to accommodate the conveying device 200. Each first positioning bottom plate 1221 has a stop portion 13 at both ends. The first end of the stop portion 13 is set higher than the first positioning bottom plate 1221 in a first direction. The two first positioning bottom plates 1221 are used to support the circuit breaker 100, and the two first positioning side plates 1211 are used to limit the circuit breaker 100 along the length direction of the circuit breaker 100. The structure of the side positioning unit 12 is suitable for the first type of circuit breaker 100. Along the length of the circuit breaker 100, two first positioning side plates 1211 limit the circuit breaker 100 to prevent the circuit breaker 100 from falling.

[0052] In other embodiments, such as Figure 5 , Figure 6 and Figure 9 As shown, the positioning side 121 also includes a second positioning side plate 1212, and the positioning bottom 122 also includes a second positioning base plate 1222. The second positioning side plate 1212 and the second positioning base plate 1222 are connected at an angle. The second positioning base plate 1222 is positioned above the first positioning base plate 1221. The first end of the stop part 13 is positioned higher than the second positioning base plate 1222 in a first direction. The second positioning side plate 1212 is positioned on the side of the first positioning side plate 1211 facing the first positioning base plate 1221, and the second positioning side plate 1212 is detachably connected to the first positioning side plate 1211. The two second positioning base plates 1222 are used to support the circuit breaker 100, and the two second positioning side plates 1212 are used to limit the circuit breaker 100 along the length direction of the circuit breaker 100. After installing the second positioning side plate 1212 on the first positioning side plate 1211 and the second positioning base plate 1222 on the first positioning base plate 1221, the structure of this side positioning unit 12 is suitable for the second type of circuit breaker 100. Along the length of the circuit breaker 100, the two second positioning side plates 1212 limit the circuit breaker 100 to prevent it from falling. In this embodiment, the side positioning unit 12 can selectively install the second positioning side plate 1212 and the second positioning base plate 1222 according to the type of circuit breaker 100 to accommodate the lifting of different types of circuit breakers 100. When the second positioning side plate 1212 and the second positioning base plate 1222 are not installed, it has the structure of the positioning side part 121 of the above embodiment, suitable for the first type of circuit breaker 100 described in the above embodiment. Furthermore, different sizes of second positioning side plates 1212 and second positioning base plates 1222 can be provided to accommodate more types of circuit breakers 100.

[0053] Optionally, a second guide slope 1213 is provided on the side of the second positioning side plate 1212 facing the second positioning base plate 1222. The second guide slope 1213 slopes downward from the upper end of the second positioning side plate 1212. The second guide slope 1213 is configured to guide the circuit breaker 100 to fit against the second positioning side plate 1212. The second guide slope 1213 adjusts the position of the circuit breaker 100 in the length direction of the circuit breaker 100, so that the circuit breaker 100 can smoothly enter between the two second positioning side plates 1212.

[0054] The first positioning side plate 1211 has a mounting groove 1214 on the side facing the first positioning base plate 1221. The second positioning side plate 1212 is placed in the mounting groove 1214, and the second positioning side plate 1212 protrudes from the mounting groove 1214 on the side facing the second positioning base plate 1222. The mounting groove 1214 serves to position the second positioning side plate 1212.
