Description

Technical Field

[0001] The invention relates to the technical field of temperature protector processing and detection, in particular to a bimetallic single-piece temperature selector. Background Art

[0002] The bimetallic strip in the temperature protector is a combination of two different alloys. When current passes through it, it will generate heat. Due to the different thermal expansion coefficients of the two different alloys, the alloys are bound to bend in one direction, and then the power is cut off when the contacts are separated. The bending speed is proportional to the current passing through, which can effectively protect the safety of electrical equipment. Since the temperature protector uses the sudden jump performance at different temperatures to complete the switch action, the temperature reversal performance of the temperature protector needs to be tested and sorted during production. It is usually necessary to limit the upper and lower limits of the temperature protection device reversal temperature, as well as the upper and lower limits of the recovery temperature. Temperature protectors within the upper and lower limits are qualified products, and those outside this range are unqualified products.

[0003] In the prior art, due to the limited inspection efficiency of workers, temperature inspection is not performed on single bimetallic strips after mass production or is only performed by random sampling. Then, temperature sorting is performed when they are assembled into finished or semi-finished temperature protectors. The products assembled in this way often have undesirable phenomena such as flickering of the assembled products due to the asymmetric temperature of the bimetallic strips, resulting in a large number of unqualified temperature protectors, which can only be scrapped as a whole, resulting in resource waste and increased production costs. Summary of the invention

[0004] The purpose of the present invention is to provide a bimetallic strip temperature sorting machine, which is suitable for mass production and can perform temperature sorting before the bimetallic strip is assembled, thereby avoiding the occurrence of undesirable phenomena such as flashing of assembled products caused by asymmetric temperature of the bimetallic strip, thereby improving the qualified rate of finished temperature protectors, reducing the scrap rate of temperature protectors, reducing waste of resources, and reducing production costs.

[0035] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0036] Reference Figure 1 , a bimetallic temperature separator disclosed in the present invention, comprising a workbench 1, a circularly arranged material channel 2 is arranged on the workbench 1, a heat preservation cover plate 3 is arranged on the top of the material channel 2, a plurality of parallel arranged heat conduction separation inclined blocks 4 are arranged in the material channel 2, a material discharge inclined surface 41 is arranged on the top of the heat conduction separation inclined block 4 toward the outside of the material channel 2, and a bimetallic positioning mechanism 42 is arranged on the material discharge inclined surface 41. The heat preservation cover plate can be an epoxy plate.

[0037] Reference Figure 2 and Figure 3 The material channel 2 includes an outer rail 25 and an inner rail 26 which is fitted in the outer rail 25. The arrangement of the inner and outer rails 25 is conducive to processing, and the materials of the two can be different. The outer rail 25 can be made of aluminum alloy with good thermal conductivity, and the inner rail 26 can be made of brass with good wear resistance and thermal conductivity.

[0038] The material channel 2 includes a rotary material channel 21 and a sorting material channel 22. A material channel heating device is provided at the bottom of the sorting material channel 22. The material channel heating device is arranged in sections so that the sorting material channel has sorting areas with different temperatures. The material channel heating device can be set as an electric heating plate, an electric heating wire, etc. The height of the side wall of the sorting material channel 22 facing outward is not higher than the height of the lower end of the material discharge slope 41. The top of the outer side wall of the sorting material channel 22 does not contact the insulation cover plate 3 and forms an action discharge port 23.

[0039] In this embodiment, the sorting channel 22 includes a low temperature zone 221 and a high temperature zone 222 connected in sequence. The temperatures of the low temperature zone and the high temperature zone are determined by the product specifications. The temperature of the low temperature zone 221 is lower than the operating temperature of qualified products, and the temperature of the high temperature zone 222 is equal to the operating temperature of qualified products. The low temperature zone 221 and the high temperature zone 222 are arranged alternately, and the tail end of the high temperature zone 222 is connected to the head end of the low temperature zone 221 through the rotary channel 21. The rotary channel 21 includes a cooling channel 212, a preheating channel 213, and a front end conveying channel 214 connected in sequence. The cooling channel 212 is connected to the rear end of the high temperature zone 222. The two are arranged in parallel, and a groove can be opened at the rear end of the two along the width direction to achieve the connection between the two. The preheating channel 213 and the low temperature zone 221 are connected by the front end conveying channel 214. The bottom of the preheating channel 213 is also provided with a channel heating device, and its temperature is less than or equal to the temperature of the low temperature zone. The preheating channel 213 is coaxially connected with the cooling channel 212; the cooling channel 212 is parallel and closely arranged with the high temperature zone 222, and the preheating channel 213 is parallel and closely arranged with the low temperature zone 221; the front conveying channel 214 is vertically arranged at the end of the preheating channel and connected with the low temperature zone.

[0040] The heat-conducting sorting inclined block 4 is in a high-temperature state when passing through the high-temperature zone 222. It passes through the rear-end conveying channel 211, the cooling channel 212, the preheating channel 213, and the front-end conveying channel 214 in sequence, and is naturally cooled in the conveying channel 2 and the cooling channel 212, and is preheated in the preheating channel 213. Therefore, when it is conveyed to the low-temperature zone 221, the bimetallic single piece 8 loaded thereon can be quickly heated by heat conduction.

[0041] To facilitate material collection, the action unloading port 23 of the low temperature zone 221 is provided with a low temperature product receiving box 223, the action unloading port 23 of the high temperature zone 222 is provided with a qualified product receiving box 224, and the outer side of the tail end of the high temperature zone 222 is provided with a high temperature product receiving box 225 that cooperates with the unloading device 7.

[0042] Pushing devices 5 for driving the rotational displacement of the heat conductive sorting inclined block 4 are respectively provided between adjacent material channels. In this embodiment, the pushing device 5 is configured as a pushing cylinder, which is fixed on the workbench 1. A pushing block 52 is fixed at the end of the piston rod of the pushing cylinder. An opening cooperating with the pushing block is provided on the side wall of the material channel. The pushing direction of the pushing cylinder is along the circulation direction of the material channel 2. The heat conductive sorting inclined block 4 is rotated and circulated in the material channel 2 by the drive of the pushing cylinder. The push cylinder includes a first cylinder 511 and a second cylinder 512 respectively located at both ends of the low temperature zone 221, a third cylinder 513 and a fourth cylinder 514 respectively located at both ends of the high temperature zone 222, and a fifth cylinder 515 and a sixth cylinder 516 respectively located at both ends of the rotary channel 21. The pushing directions of the first cylinder 511 and the second cylinder 512 are perpendicular to each other, the pushing directions of the third cylinder 513 and the fourth cylinder 514 are perpendicular to each other, and the pushing directions of the fifth cylinder 515 and the sixth cylinder 516 are perpendicular to each other. A stopper 27 cooperating with the push cylinder is provided at the end opening of the channel 2 to prevent the heat conduction sorting inclined block 4 from leaving the channel during the pushing process. Each pushing distance is the spacing of a heat conduction sorting inclined block 4, and the heat conduction sorting inclined blocks 4 are slowly circulated and transported one by one.

[0043] Reference Figure 3 and Figure 4 The front conveying channel 214 and the rear conveying channel 211 are respectively provided with a loading device 6 and a unloading device 7. The loading device 6 is arranged at the front end of the low temperature zone 221, and the unloading device 7 is arranged at the rear end of the high temperature zone 222.

[0044] The feeding device 6 includes a feeding cylinder 61, a first slide 62, a first cylinder bracket 63, and a feed block 64. The first cylinder bracket 63 is fixed on the workbench 1. The feeding cylinder 61 is connected to the first cylinder bracket 63 through the first slide 62. The displacement direction of the first slide 62 is from outside the material channel to inside the material channel. The end of the piston rod of the feeding cylinder 61 is fixed with a first electromagnet 65 for adsorbing the bimetallic single piece 8. The feed block 64 is fixed on the workbench 1, and a feed trough 641 is provided on the top of the feed block 64. A feed vibration disk 66 is connected to the side of the feed trough 641. The bimetallic single piece is automatically fed to the feed trough 641 through the vibration disk 66, and the feeding cylinder 61 slides through the first slide 62 to move the end of the piston rod with the first electromagnet 65 to the top of the feed trough 641. The piston rod of the feeding cylinder 61 extends, and the first electromagnet 65 absorbs a bimetallic single piece 8 and then retracts the piston rod and slides the first slide 62 to move the bimetallic single piece 8 to the heat-conducting sorting inclined block 4 located in the material channel 2. The bimetallic single piece 8 is pre-positioned on the heat-conducting sorting inclined block 4 by the bimetallic positioning mechanism 42, and will not slide when the heat-conducting sorting inclined block 4 is displaced. Only when it is heated to the operating temperature, its sudden jump action disengages from the bimetallic positioning mechanism 42 and discharges along the discharge inclined surface 41.

[0045] The unloading device 7 includes an unloading cylinder 71, a second slide 72, and a second cylinder bracket 73. The second cylinder bracket 73 is fixed on the workbench 1. The unloading cylinder 71 is connected to the second cylinder bracket 73 through the second slide 72. The displacement direction of the second slide 72 is from the inside of the material channel to the outside of the material channel. The piston rod end of the unloading cylinder 71 is fixed with a second electromagnet 74 for adsorbing the bimetallic single piece 8. The bimetallic single piece that does not move after being sorted in the low temperature zone 221 and the high temperature zone 222 is adsorbed by the unloading cylinder 71, and the bimetallic single piece on the heat-conducting sorting inclined block 4 is adsorbed and transferred to the outside of the material channel 2.

[0046] Reference Figures 4 to 10 In this embodiment, the heat-conducting sorting inclined block 4 is set as a wedge-shaped block made of brass or copper. The inclination angle of the material cutting inclined surface 41 is 20-60°, and preferably about 30 degrees can be selected. Of course, the inclination angle is not limited to the above angle, as long as the bimetallic single piece 8 can be cut along the inclined surface after the temperature rises and jumps. The bimetallic positioning mechanism 42 on the material cutting inclined surface 41 can be adaptively designed according to the different models and specifications of the bimetallic single piece 8:

[0047] like Figures 4 to 6 For the bimetallic single piece 8 with silver dots and holes, a pin 421 corresponding to the hole can be set on the cutting slope 41. The bimetallic single piece 8 is lightly hung on the cutting slope 41 through the cooperation of the silver dots and the pin 421. When it jumps due to heat, the hole and the pin 421 are separated and the material is cut along the cutting slope 41.

[0048] like Figure 7 and Figure 8 For the bimetallic single piece 8 with silver dots but no holes, a silver dot embedding groove 422 corresponding to the silver dots can be set on the cutting slope 41. The bimetallic single piece 8 is lightly hung on the cutting slope 41 through the cooperation of the silver dots and the silver dot embedding groove 422. When it is heated, it can pop out of the silver dot embedding groove 422 and cut along the cutting slope 41.

[0049] like Fig. 9 and Fig.10 For the bimetallic single piece 8 without silver spots and holes, a shallow notch 423 can be set on the cutting slope 41. The arched surface of the bimetallic single piece 8 faces the shallow notch 423 and is embedded in the shallow notch 423. When it jumps suddenly due to heat, it can pop out of the shallow notch 423 and cut along the cutting slope 41.

[0050] The implementation principle of this embodiment is: the whole set of heat-conducting sorting inclined blocks circulates in the material channel, and the heat-conducting sorting inclined blocks are preheated by the preheating material channel before entering the sorting material channel, so that they can maintain a precise and constant temperature when they reach the temperature selection zone of the sorting material channel. The temperature zone of the sorting material channel is divided into a low-temperature zone and a high-temperature zone (the temperature is determined by the product specifications). When the double pieces jump in the low-temperature zone and fall rapidly due to the action of the inclined surface, this product is a low-temperature product (unqualified product), and the double pieces that do not jump continue to run to the high-temperature zone. The double pieces that jump and fall in the high-temperature zone are qualified products. The double pieces that do not fall are taken out by the unloading device at the end outlet of the material channel, and this product is an unqualified product (high-temperature product).

[0051] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
