Description

Technical Field

[0001] This application relates to the field of fuse testing technology, specifically to a silver plating testing device for new energy vehicle fuses. Background Technology

[0002] New energy vehicle fuses are an important safety device, mainly used to protect the circuit system of electric vehicles and prevent overcurrent from threatening the safety of electric vehicles and passengers. The fuse housing is usually composed of plastic and copper busbar, and has the requirement of high temperature resistance. PPS is often used as the plastic raw material.

[0003] However, the existing fuse testing process has the following defects: Due to the high injection temperature of PPS, the copper busbar will turn red and oxidize during the production process. Therefore, the copper busbar needs to be polished to remove the oxide film before the fuse is tested. However, the polished copper busbar is still prone to oxidation, which leads to increased contact resistance of the product and affects the overall performance and test results. Therefore, a protective agent needs to be applied to the copper busbar of the fuse after polishing. At present, the application of protective agent mostly relies on manual labor, which is inefficient and inaccurate. During the application, the protective agent is prone to dripping or spreading to the surrounding area of ​​the copper busbar. Summary of the Invention

[0004] One objective of this application is to provide a silver plating testing device for new energy vehicle fuses that can quickly and accurately apply a protective agent.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a silver plating detection device for fuses in new energy vehicles, comprising a container, a liquid dispensing mechanism, and a triggering mechanism. The liquid dispensing mechanism includes a delivery pump and multiple liquid dispensing modules. The delivery pump is connected to the container and the liquid dispensing modules. The container is adapted to deliver solvent to the liquid dispensing modules via the delivery pump. The fuse is adapted to be inverted onto the liquid dispensing modules. The liquid dispensing modules are adapted to coat the copper busbar inside the fuse with solvent. The triggering mechanism includes a marking module, a linkage module, and a valve module. The marking module is elastically floating near the liquid dispensing modules. The marking module is adapted to mark the fuse inverted onto the liquid dispensing modules.

The valve module is adapted to control the on / off state of the liquid dispensing modules. The marking module is adapted to be pressed down by the fuse to drive the linkage module to activate the valve module, causing the liquid dispensing modules to release solvent.

[0006] In some embodiments, the liquid outlet module includes a liquid outlet column and a buffer pad. The buffer pad is disposed at the top of the liquid outlet column. A liquid outlet channel is formed inside the liquid outlet column. One end of the liquid outlet channel is connected to the buffer pad. The buffer pad has a porous structure and is adapted to uniformly absorb the solvent flowing out of the liquid outlet channel. When the fuse is reversed, the copper busbar and the buffer pad are adapted to be interference-fitted, and the buffer pad is adapted to release solvent to the copper busbar.

[0007] In some embodiments, the valve module includes a valve plate, the liquid outlet column has a connection port on one side of the liquid outlet channel, the valve plate is disposed at the connection port, the valve plate is adapted to pass through the connection port and cooperate with the liquid outlet channel, and the valve plate is adapted to be close to or away from the liquid outlet channel to control the opening and closing of the liquid outlet channel.

[0008] In some embodiments, the linkage module includes a first fixed seat, a second fixed seat, two guide posts, and an elastic body. The guide posts are connected to the valve module. Each guide post has a first end and a second end, the diameter of the second end being larger than the diameter of the first end. The first end and the first fixed seat are slidably connected along a first direction, and the second end and the second fixed seat are slidably connected along a second direction. The first end is adapted to create a movable gap with the second fixed seat in the first direction within the second fixed seat. The two ends of the elastic body are combined with the second ends of the two guide posts, and the middle part of the elastic body is combined with the bottom of the marking module. When the marking module is pressed down, the elastic body is adapted to drive the guide posts to move along the second direction. When the second end of the guide post disengages from the second fixed seat, the elastic body is adapted to drive the guide post to slide along the first direction.

[0009] In some embodiments, a control mechanism is further included, the control mechanism including a proximity sensing module and a controller, the proximity sensing module being disposed near the liquid outlet module, the proximity sensing module being adapted to sense the action of the fuse being placed on the liquid outlet module, the proximity sensing module being connected to the controller, the controller having an actively retractable control end, the control end being adapted to drive the valve plate closer to the liquid outlet channel and drive the guide post to reset.

[0010] In some embodiments, the number of valve modules is two, the valve modules are symmetrically arranged on both sides of the marking module, and the valve modules are located on the side of the liquid outlet module away from the marking module in a first direction.

[0011] In some embodiments, the liquid dispensing module includes a liquid dispensing column with a liquid dispensing channel inside. The liquid dispensing column has a connection port on the side of the liquid dispensing channel away from the marking module. The valve module includes a valve plate, which is simultaneously disposed at the connection ports of multiple liquid dispensing columns on the same side of the marking module. The valve plate is adapted to pass through the connection port and cooperate with the liquid dispensing channel. The valve plate is adapted to be close to or away from the liquid dispensing channel to control the opening and closing of the liquid dispensing channel.

[0012] In some embodiments, an elastic reset member is provided between the second fixed base and the marking module, the elastic reset member being adapted to lift and reset the marking module upwards.

[0013] In some embodiments, the guide post is a general bolt, the elastomer is a strip structure, the second end of the guide post is provided with an operating port, and the end of the elastomer is adapted to be inserted into the operating port to engage with the guide post.

[0014] In some embodiments, a plurality of positioning pins are further included, the positioning pins being distributed around the liquid dispensing module, the positioning pins being adapted to connect with mounting holes on the fuse to fix the fuse and the liquid dispensing module relative to each other; the fuse has a recessed chamber, and the liquid dispensing mechanism is adapted to coat the copper busbar in the recessed chamber with solvent.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] 1. The silver plating detection device of this application, through the design of the liquid dispensing module, enables precise coating of protective agent onto the copper busbar inside the inverted fuse from bottom to top. This silver plating method can effectively reduce the probability of protective agent dripping and spreading to the surrounding copper busbar, saving resources and reducing pollution. At the same time, the protective agent outflow control linkage of the liquid dispensing module is linked to the marking module, which only triggers liquid dispensing when the marking module is pressed down and marked, so that the fuse can be marked while the protective agent is being applied, which is convenient for later identification and classification.

[0017] 2. The silver plating detection device of this application achieves precise coating of copper busbars by wetting the buffer pad, thereby further reducing the probability of protective agent dripping and spreading to the surrounding area of ​​the copper busbars.

[0018] 3. The linkage module of the silver plating detection device of this application has strong operational feedback. When the liquid dispensing module is turned on, the elastomer drives the guide column to move and generate a small impact, which in turn produces a sound. This makes it easy for operators to identify whether the coating process has started, improving operational convenience and production efficiency. At the same time, the control mechanism senses the placement of the fuse. When the fuse is not placed, even if the marker module is pressed down and triggered, the liquid dispensing module will not be turned on, thus avoiding the liquid dispensing module being accidentally triggered and causing the protective agent to flow out and spill.

[0028] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

They should not be construed as limiting the specific protection scope of this application.

[0030] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0031] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0032] The following description, in conjunction with the accompanying drawings, further illustrates this application:

[0033] like Figures 1 to 8 As shown, this application provides a silver plating testing device for new energy vehicle fuses. The silver plating testing device of this application mainly discloses the relevant equipment for the process of applying silver protective agent to copper busbar 11 during the testing process of fuse 1. The fuse 1 needs to undergo insulation withstand voltage and insulation resistance tests after the silver protective agent process is completed.

[0034] like Figures 1 to 3As shown, the silver plating detection device mainly includes a container 3, a liquid dispensing mechanism 4, and a triggering mechanism 5. The container 3, the liquid dispensing mechanism 4, and the triggering mechanism 5 are all arranged on the workbench 2. The liquid dispensing mechanism 4 includes a delivery pump 41 and multiple liquid dispensing modules 42. The delivery pump 41 connects the container 3 and the liquid dispensing modules 42. The container 3 is adapted to deliver solvent to the liquid dispensing modules 42 through the delivery pump 41. The specific operation of the liquid dispensing module 42 on the silver plating protective agent of the fuse 1 is as follows: the fuse 1 is inverted, and the copper busbar 11 with the coating surface facing down is placed on the liquid dispensing module 42. The top of the liquid dispensing module 42 is adapted to dispense liquid to coat the coating surface of the copper busbar 11 inside the fuse 1 above. The purpose of this design is to improve the accuracy of coating the copper busbar 11 with solvent, reduce the interference of solvent dripping due to gravity, so that the copper busbar 11 can be coated evenly. Even if the solvent drips, it will not enter and remain inside the fuse 1, so that the part of the fuse 1 other than the copper busbar 11 can be kept as clean as possible.

[0035] In some embodiments, container 3 is a glue bucket, and the bottom of the glue bucket is connected to the liquid dispensing mechanism 4 for liquid dispensing.

[0036] In some embodiments, the delivery pump 41 is a peristaltic pump, which has the characteristics of high delivery accuracy, strong self-priming ability, small size and quiet operation, and is more suitable for the delivery of silver protective agent.

[0037] like Figure 1 and 4 As shown, the triggering mechanism 5 includes a marking module 51, a linkage module 52, and a valve module 53. The marking module 51 is elastically floating near the liquid outlet module 42. Specifically, the marking module 51 can be pressed down and elastically reset after the external pressure is released. At the same time, the top of the marking module 51 has a marking point. When the fuse 1 is placed on the marking module 51 and the liquid outlet module 42, the marking point is suitable for contacting the fuse 1 and leaving a mark on the fuse 1, so as to facilitate the operator to identify and judge whether the fuse 1 has been coated with silver protective agent, thereby facilitating subsequent classification and sorting.

[0038] Understandably, the marking points of the marking module 51 can be used to leave removable or non-removable markings on the fuse 1 using conventional marking methods such as pigments, hot pressing, and scratching.

[0039] Simultaneously, the linkage module 52 connects the marking module 51 and the valve module 53. The valve module 53 is connected to the liquid outlet module 42 and is adapted to control the on / off state of the liquid outlet module 42. The marking module 51 is adapted to be pressed down by the fuse 1 to drive the linkage module 52 to drive the valve module 53 to act, so that the liquid outlet module 42 releases solvent. By linking the triggering operation of the marking module 51 with the action of the valve module 53, the liquid outlet module 42 can release solvent synchronously when the marking module 51 is pressed down, so that the liquid outlet module 42 has a sufficient amount of liquid to coat the copper busbar 11.

[0040] Furthermore, the triggering operation of the marking module 51 can be connected to the operation of the delivery pump 41 through limit switch sensing and other means, so that the delivery pump 41 can start simultaneously to deliver solvent when the marking module 51 is pressed down, thereby achieving energy-saving operation and improving the liquid discharge efficiency of the liquid discharge module 42, and avoiding blockage.

[0041] like Figure 3 In the illustrated embodiment, the liquid outlet module 42 includes a liquid outlet column 421 and a buffer pad 422. The buffer pad 422 is disposed at the top of the liquid outlet column 421. A liquid outlet channel 4211 is provided inside the liquid outlet column 421. One end of the liquid outlet channel 4211 is connected to the buffer pad 422. The buffer pad 422 has a porous structure and is suitable for uniformly absorbing the solvent flowing out of the liquid outlet channel 4211. When the fuse 1 is flipped over, the copper busbar 11 and the buffer pad 422 are suitable for interference fit. The solvent in the buffer pad 422 is suitable for being squeezed out due to the compression of the buffer pad 422, thereby releasing the solvent to the copper busbar 11. This method is convenient to operate, provides uniform and fast coating, can greatly improve the utilization rate of solvent, reduce waste and pollution, and is conducive to improving the efficiency of subsequent production and processing.

[0042] like Figure 3 In the embodiment shown, one end of the liquid outlet channel 4211 is connected to the buffer pad 422 in a multi-channel manner along the radial direction of the liquid outlet column 421. The liquid in the liquid outlet channel 4211 can flow more evenly onto the buffer pad 422, thereby improving the uniformity of coating.

[0043] In some embodiments, the buffer pad 422 is a sponge pad with strong liquid absorption and release capabilities, which can better store solvent and prevent solvent from dripping or flowing down when not affected by external forces.

[0044] like Figure 3In the illustrated embodiment, to prevent excessive solution from dripping from the top of the liquid outlet column 421 due to the compression of the buffer pad 422, a support sleeve 423 is provided on the top periphery of the liquid outlet column 421. The lower part of the buffer pad 422 is placed on the support sleeve 423. The support sleeve 423 can receive the solvent flowing down from the buffer pad 422, reducing dripping. At the same time, it can also make the buffer pad 422 more uniformly compressed in conjunction with the downward pressure of the copper busbar 11, improving the uniformity of coating.

[0045] The support sleeve 423 also facilitates the installation and replacement of the buffer pad 422, improving maintainability. When installing the buffer pad 422, simply nest it into the top of the liquid outlet column 421, and then press it to embed the lower part of the buffer pad 422 into the support sleeve 423 to quickly complete the installation.

[0046] like Figure 4 and 6 In the illustrated embodiment, the valve module 53 includes a valve plate 531. The liquid outlet column 421 has a connection port 4212 on one side of the liquid outlet channel 4211. The valve plate 531 is disposed at the connection port 4212. The valve plate 531 is adapted to pass through the connection port 4212 and cooperate with the liquid outlet channel 4211. The valve plate 531 is adapted to be close to or away from the liquid outlet channel 4211 to control the opening and closing of the liquid outlet channel 4211. The flow rate of the liquid outlet channel 4211 can be easily and conveniently controlled by the valve plate 531.

[0047] Understandably, when performing continuous operation, in order to improve the liquid discharge efficiency of the liquid discharge channel 4211 and prevent the buffer pad 422 from drying out, the action of the valve plate 531 can be set to change the flow cross-sectional size of the liquid discharge channel 4211, so as to partially block the liquid discharge channel 4211, so that the buffer pad 422 can continuously obtain solvent.

[0048] It is worth noting that when the valve plate 531 is away from the liquid outlet channel 4211, it does not detach from the connection port 4212. It is necessary to keep the connection port 4212 closed to prevent the solvent in the liquid outlet channel 4211 from leaking from the connection port 4212.

[0049] In fact, some fuses 1 have a recessed chamber 12, and one end of the copper busbar 11 extends into the recessed chamber 12. The liquid outlet module 42 in the form of the liquid outlet column 421 of this application is suitable for extending into the recessed chamber 12 to coat the copper busbar 11 with solvent, and it is not easy for the solvent to stand on the inner wall of the recessed chamber 12, which can reduce the cleaning difficulty.

[0050] like Figure 7 and 8In the illustrated embodiment, the linkage module 52 includes a first fixed base 521, a second fixed base 522, two guide posts 523, and an elastic body 524. The guide posts 523 are connected to the valve module 53. The guide posts 523 have a thinner first end 5231 and a thicker second end 5232. The diameter of the second end 5232 is larger than the diameter of the first end 5231. The first end 5231 and the first fixed base 521 are slidably connected along a first direction x, and the second end 5232 and the second fixed base 522 are slidably connected along a second direction y. 1. The elastic body 524 is adapted to create a movable gap 6 with the second fixed seat 522 in the first direction x. The two ends of the elastic body 524 are combined with the second ends 5232 of the two guide posts 523. The middle part of the elastic body 524 is combined with the bottom of the marking module 51. When the marking module 51 is pressed down, the elastic body 524 is adapted to drive the guide post 523 to move in the second direction y. When the second end 5232 of the guide post 523 is disengaged from the second fixed seat 522, the elastic body 524 is adapted to drive the guide post 523 to slide in the first direction x.

[0051] When the second end 5232 of the guide post 523 is located inside the second fixed seat 522, due to the obstruction of the second end 5232, although a movable gap 6 is formed between the first end 5231 and the second fixed seat 522, the first end 5231 cannot move relative to the second fixed seat 522 in the first direction x. After the second end 5232 extends out of the second fixed seat 522, the obstruction of the first end 5231 disappears. Under the drive of the elastic body 524, the guide post 523 is suitable for movement, and the movable gap 6 between the first end 5231 and the second fixed seat 522 will be eliminated. At this time, the valve plate 531 connected to the guide post 523 will also move synchronously and open the liquid outlet channel 4211.

[0052] It is understandable that when the guide post 523 extends out of the second fixed seat 522 and moves, it will move rapidly under the drive of the elastic body 524, and then hit the second fixed seat 522. This process will produce sound and vibration, which can be easily perceived by the operator. Therefore, the linkage module 52 of this application also has good operation feedback, which makes it convenient for the operator to judge whether the liquid outlet channel 4211 is opened smoothly, and thus know whether the silver plating protective agent is working properly.

[0053] It is worth noting that after the second end 5232 extends out of the second fixed seat 522 and the guide post 523 moves, structural interference will occur between the second end 5232 and the second fixed seat 522 in the second direction y. At this time, the guide post 523 is subjected to the continuous action of the elastic body 524 and cannot be reset. The marking module 51 also cannot be lifted and reset. Therefore, this application also discloses a control mechanism 7, which actively drives the guide post 523 to reset so that the linkage module 52 can operate normally.

[0054] like Figures 4 to 8 In the illustrated embodiment, the control mechanism 7 includes a proximity sensing module 71 and a controller 72. The proximity sensing module 71 is located near the liquid outlet module 42 and is adapted to sense the action of the fuse 1 being placed on the liquid outlet module 42. The proximity sensing module 71 is connected to the controller 72, which has an actively retractable control end. The control end is adapted to drive the valve plate 531 to approach the liquid outlet channel 4211 and drive the guide post 523 to reset. The main function of the control mechanism 7, in addition to helping the guide post 523 to reset, is to lock it when the proximity sensing module 71 is in use.

[0055] It is worth noting that the control terminal needs to be decoupled from the valve plate 531 so that the valve plate 531 will not move away from the liquid outlet channel 4211 with the control terminal. At this time, the control mechanism 7 can work with the linkage module 52 to prevent accidental contact. When the marker module 51 is not pressed down when the fuse 1 is placed, the valve plate 531 will not open because the proximity sensing module 71 does not sense the approach of an object. When the proximity sensing module 71 senses the approach of an object, even if the control mechanism 7 is unlocked, the guide post 523 cannot move with the second fixed seat 522 in the first direction x because the marker module 51 is not pressed down. Therefore, the valve plate 531 cannot move. Only when the proximity sensing module 71 senses the object and the marker module 51 is pressed down can the liquid outlet module 42 dispense liquid. The above operation logic can free the operation of the silver plating protective agent from manual control, effectively improve the operation efficiency, and achieve more precise liquid coating.

[0056] In some embodiments, the controller 72 may use devices such as motors, cylinders, and hydraulic cylinders, which can be freely selected according to the spatial arrangement of the silver plating detection device.

[0057] In some embodiments, the proximity sensing module 71 is an infrared sensor or a proximity switch, which can accurately sense the placement action of the fuse 1.

[0058] like Figure 6 In the embodiment shown, there are two valve modules 53, which are symmetrically arranged on both sides of the marking module 51. The valve modules 53 are located on the side of the liquid outlet module 42 away from the marking module 51 in the first direction x. The main purpose is to adapt to the structural arrangement of the guide posts 523 connected to both ends of the elastomer 524, so that each of the two guide posts 523 can be connected to a valve module 53 for linkage, thereby effectively associating the action of the marking module 51 with the action of the valve module 53.

[0059] like Figure 6In the embodiment shown, the valve plate 531 is simultaneously disposed at the connection port 4212 of multiple liquid outlet columns 421 on the same side of the marking module 51. The valve plate 531 is adapted to pass through the connection port 4212 and cooperate with the liquid outlet channel 4211. The valve plate 531 is adapted to be close to or away from the liquid outlet channel 4211 to control the opening and closing of the liquid outlet channel 4211. That is, the valve plate 531 can simultaneously control the channels of the liquid outlet channels 4211 on multiple liquid outlet columns 421, so that the structural arrangement of the guide post 523 connected to both ends of the elastomer 524 can adapt to the coating control requirements of more copper busbars 11 and improve the structural applicability.

[0060] In some embodiments, an elastic reset member 8 is provided between the second fixed base 522 and the marking module 51. The elastic reset member 8 is adapted to lift the marking module 51 upwards and reset it. During this process, the control mechanism 7 needs to play a cooperating role. When the fuse 1 is picked up, the proximity sensing module 71 detects that the object has disappeared. The control mechanism 7 is activated, pushing the valve plate 531 to move and driving the second end 5232 of the guide post 523 to overcome the action of the elastic body 524 and dock with the second fixed base 522. At this time, the obstruction of the marking module 51 in the second direction y disappears and it can be lifted by the elastic reset member 8. The marking module 51 can synchronously drive the second end 5232 of the guide post 523 into the second fixed base 522 for reset through the elastic body 524 connected to its bottom.

[0061] like Figure 7 and 8 In the embodiment shown, the elastic reset member 8 is a spring, the marking module 51 has a columnar structure, and the spring is sleeved on the periphery of the columnar structure.

[0062] In some embodiments, the guide post 523 is a general-purpose bolt, the elastic body 524 is a strip structure, the second end 5232 of the guide post 523 is provided with an operating port, the end of the elastic body 524 is adapted to be inserted into the operating port, and is combined with the guide post 523 by means of adhesive, welding or other methods. Because each time the silver plating protective agent is applied, the guide post 523 will impact the second fixing seat 522 under the drive of the elastic body 524. Long-term use is prone to wear, deformation or even damage, making the guide post 523 a consumable part. Using a general-purpose bolt as the guide post 523 can not only facilitate the fixing with the valve module 53, but also effectively reduce the cost of use and improve maintainability by simply and firmly assembling the elastic body 524 with the general-purpose bolt.

[0063] like Figure 1 and 2 In the embodiment shown, the silver plating detection device of this application also includes a plurality of positioning pins 9, which are distributed around the liquid outlet module 42. The positioning pins 9 are adapted to connect with the mounting holes on the fuse 1 so that the fuse 1 and the liquid outlet module 42 are relatively fixed.

[0064] Understandably, the number and position of the positioning pins 9 can be arranged according to the shape of the fuse 1, so that the fuse 1 can make stable and balanced contact with the liquid outlet module 42, thereby improving the coating effect of the silver protective agent.

[0065] In some embodiments, the upper diameter of the positioning pin 9 is smaller than its lower diameter, which can reduce the difficulty of docking with the mounting hole of the fuse 1 and improve the placement accuracy and efficiency of the fuse 1.

[0066] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are only the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope of this application. All such changes and modifications fall within the scope of this application as claimed. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
