Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding devices, and in particular to a welding equipment for capacitors in new energy vehicles. Background Technology
[0002] As a fundamental electronic component, capacitors are widely used in electrical fields such as new energy vehicles due to their functions of storing charge, smoothing voltage, filtering, and phase shifting. In the capacitor assembly and manufacturing process, multiple capacitor elements and various components are typically assembled manually and then soldered to both sides. However, this production method suffers from problems such as being time-consuming and labor-intensive, having low production efficiency, high costs, unstable product quality, and a low product qualification rate. Therefore, existing technologies increasingly employ automated production lines for capacitor soldering.
[0003] During the welding process, both sides of the capacitor need to be welded simultaneously. Existing technology includes equipment for welding capacitors, specifically a production line. This production line, to achieve the welding of capacitor components, is sequentially set up along the transport direction of the conveyor line with a blowing station, a loading station, a first inspection station, a first preheating station, a first welding station, a flipping station, a second preheating station, a second welding station, and a second inspection station. In use, the tooling is first blown clean, then manually loaded and inspected at the first inspection station to ensure the raw materials are in good condition before welding. The components to be welded are then preheated, followed by the first welding, completing the welding on one side. The workpiece is then flipped to facilitate the second welding from top to bottom. Of course, the workpiece still needs to be preheated before the second welding. At this point, the welding of the capacitor component is complete. The capacitor component needs to be inspected to check if the weld points are qualified, thus determining the overall welding quality. During the inspection process, a camera and a flipping mechanism are installed. By flipping, the two sides of the capacitor component are alternately arranged facing upwards, facilitating inspection of both sides by a single camera. In addition, a return conveyor belt is installed below the production line, in the opposite direction to the aforementioned transport, to transport the soldered capacitors to the loading point.
[0004] In the aforementioned technical solutions, the fixture often has multiple capacitors. During testing, the camera needs to be positioned at different locations, meaning the camera is testing while the fixture is moving forward. The conveyor belt is a circular conveyor belt, typically connected to the fixture via friction. Even if the conveyor belt moves at a constant speed during camera testing, it's impossible to guarantee that the fixture on the belt will move at a constant speed. For example, to avoid motion blur during testing, the camera often needs to stop to bring the capacitor to a standstill before taking the picture. Since the chain and fixture are only connected by friction during transmission, when the chain stops, inertia causes the capacitor to continue moving forward, resulting in the camera not capturing the desired image and unclear test results. Furthermore, the capacitors tested by the camera need to be flipped for retesting. After single-sided testing, the capacitors have already moved downstream. To flip them for secondary testing, the conveyor belt needs to reverse, transporting the downstream capacitors upstream for the camera to test again. Inaccurate positioning is impossible during the forward and reverse rotation of the conveyor belt. Utility Model Content
[0005] In view of this, the present invention provides a welding equipment for capacitors in new energy vehicles, which solves the problem in the prior art that in order for the camera to detect the capacitor, it is necessary to keep the capacitor at a constant speed during the detection process. However, due to the friction between the conveyor belt and the transport table, it is not easy to keep the capacitor's transport speed constant, resulting in poor detection accuracy.
[0006] A capacitor welding equipment for new energy vehicles includes a frame and a flexible transmission component mounted on the frame. The flexible transmission component is used to transport a transport table equipped with capacitors to be welded by rotation. A first welding station, a first flipping station, a second welding station, a visual inspection station, and a second flipping station are sequentially arranged along the transport direction of the flexible transmission component. A transport mechanism with switchable transport direction is arranged between the visual inspection station and the second flipping station. The transport mechanism includes a recovery transport chain flush with the height of the flexible transmission component for receiving the transport table and a slide table arranged at the bottom of the recovery transport chain and driving the overall movement of the recovery transport chain. A positioning mechanism for locking the position of the transport table is also provided on the recovery transport chain.
[0007] Furthermore, the frame includes a slide block for guiding the sliding table, which spans the vision inspection station and the second flipping station along the transmission direction of the flexible component.
[0008] Furthermore, the slide table is equipped with a servo motor that drives the slide table to move relative to the slide base.
[0009] Furthermore, the visual inspection station is equipped with a camera and a support frame for mounting the camera. The support frame is also equipped with a lateral translation mechanism that moves along the transmission direction perpendicular to the transmission flexible component. The camera is indirectly mounted on the support frame through the lateral translation mechanism to achieve lateral movement of the camera.
[0010] Furthermore, the output end of the lateral translation mechanism is provided with a lifting mechanism, and the camera is fixedly mounted on the output end of the lifting module.
[0011] Furthermore, the visual inspection station is equipped with a visual inspection module, which includes a camera and a supplementary light. The supplementary light includes a spherical lampshade with an opening in the center, and the camera is positioned at the opening in the center of the lampshade.
[0012] Furthermore, the flexible transmission component is segmented, with a segment of the flexible transmission component provided at the first welding station, the first flipping station, and the second welding station.
[0013] Furthermore, each flexible transmission component includes parallel transmission chains, which are used to slide against the bottom of the transport platform to drive the transport platform to move under the action of friction.
[0014] Furthermore, the frame includes a boss whose height exceeds that of the transmission chain and is located outside the transmission chain, and a limiting block located inside the boss is provided on the transport platform.
[0015] Furthermore, the limiting blocks are provided on both sides of the transport platform.
[0016] The beneficial effects of the new energy vehicle capacitor welding equipment of this utility model are as follows: The new energy vehicle capacitor welding equipment of this utility model facilitates the transport of the transport platform by setting up a flexible transmission component, thereby facilitating the transport of capacitors. A first welding station, a first flipping station, a second welding station, a visual inspection station, and a second flipping station are sequentially arranged in the transmission direction of the flexible transmission component to facilitate welding and inspection of both sides of the capacitors. A conveyor mechanism with switchable transport direction is set between the visual inspection station and the second flipping station to facilitate transfer between the two stations. This allows the capacitors that have undergone initial inspection to be sent to the second flipping station for flipping, and also facilitates the transfer of the flipped capacitors. The capacitor is then transported to the visual inspection station for secondary inspection. The use of a sliding table facilitates transport and precise position control. A retrieval conveyor chain, at the same height as the flexible transport component, is installed on the sliding table to receive the capacitor from upstream. A positioning mechanism on the retrieval conveyor chain locks the position of the capacitor, ensuring that its position can only be controlled by the sliding table. This allows for precise position control and solves the problem in existing technologies where maintaining a constant speed for the capacitor during inspection is difficult due to friction between the conveyor belt and the transport table, leading to poor inspection accuracy.

[0035] In Embodiment 1 of the new energy vehicle capacitor welding equipment of this utility model,
[0036] like Figure 1 and Figure 2As shown, the new energy vehicle capacitor welding equipment in this embodiment includes a frame with a flexible transmission component on it. Specifically, the flexible transmission component is a segmented transmission chain 31, which is a ring chain that can rotate cyclically by a drive motor. Along the conveying direction of the flexible transmission component, the frame is sequentially equipped with a first welding station 12, a first flipping station 13, a second welding station 14, a visual inspection station 15, and a second flipping station 16. Each of the first welding station 12, the first flipping station 13, and the second welding station 14 has a section of the transmission chain 31. This design not only shortens the manufacturing size of the transmission chain 31 for easier processing and manufacturing, but also enables modular manufacturing and assembly. That is, the equipment corresponding to each station is manufactured separately and then assembled together to form the equipment. Simultaneously, to facilitate the transportation of capacitors, such as... Figure 3 and Figure 4 As shown, this embodiment also includes a transport platform 2 adapted to the capacitor. The transport platform 2 contacts the upper surface of the transmission chain 31, and the transport platform 2 is driven forward by the friction between the transport platform 2 and the transmission chain 31. Specifically, the transport platform 2 includes a base 21 and a holding platform 22 that are fastened together by snap-fit. The holding platform 22 is provided with a capacitor placement hole 24 for holding the capacitor. The capacitor placement hole 24 is a through hole, so that both sides of the capacitor can be exposed after it is placed. The base 21 is provided with a through hole corresponding to the position of the holding platform 22. This through hole allows the capacitor placement hole 24 on the holding platform to be exposed, that is, the capacitor on the holding platform 22 can be directly contacted from the back. In other words, even if soldering is done from the back, it will not be impossible to solder due to the obstruction of the base 21, which facilitates soldering from both sides of the capacitor. Of course, in other embodiments, a longer section of the transmission chain can also be provided at the first soldering station, the first flipping station, and the second soldering station.
[0037] like Figure 1 and Figure 2As shown, when using this equipment, welding is generally performed first at the first welding station 12, where single-sided welding of the capacitor is completed. Next, welding of the other side of the capacitor is required. Since the capacitor is placed with one side facing up and the other side facing down, it needs to be flipped to expose the other side. Therefore, a flipping mechanism is provided at the first flipping station 13 to facilitate flipping the capacitor. After being flipped by the flipping mechanism at the first flipping station 13, the unwelded side faces up, and welding of the second side is then performed at the second welding station 14, thus achieving double-sided welding of the capacitor. After the capacitor welding is completed, inspection is required to determine the quality of the capacitor welding. Specifically, a visual inspection station 15 is provided. Since the quality of both sides of the capacitor needs to be inspected separately, and the visual inspection station 15 only has one visual inspection mechanism, it can only inspect one side of the capacitor. If the second side needs to be inspected, another flipping is required. Therefore, a second flipping station 16 is provided downstream of the visual inspection station 15.
[0038] The flipping mechanisms at the first flipping station 13 and the second flipping station 16 have the same structure. Taking one of them as an example, the structure of the flipping mechanism will be described. Specifically, as follows... Figure 9 and Figure 10 As shown, the tilting mechanism includes a tilting frame 61, which is a portal frame. The portal frame includes four support columns connected to the frame body. Support plates are installed on the support columns. A lifting cylinder 61 is installed at the center of the support plate. The cylinder body of the lifting cylinder 61 is located above the support plate, and its telescopic end extends downward through the support plate. A connecting plate 63 is installed at the end of the telescopic end, thereby controlling the vertical movement of the connecting plate 63. To make the connecting plate 63 more stable during movement, a guide column 64 is also provided. The guide column 64 is positioned between the connecting plate 63 and the support plate, and the connecting plate 63 is more stable during movement due to the guidance of the guide column 64. To flip the transport platform 2, it needs to be clamped. A push cylinder is installed at the bottom of the connecting plate 63, and a mounting plate 65 is fixedly connected to the output shaft of the push cylinder. A positioning pin is installed on one side of the mounting plate 65, and a flipping power source 66 is installed on the back of the other side of the mounting plate 65. Two flipping positioning pins 67 are connected to the output shaft of the flipping power source 66. The rotation axes of the two flipping positioning pins 67, the flipping axis of the flipping power source 66, and the axis of the positioning pin on the other side are collinear, which facilitates the flipping of the transport platform 2. In this embodiment, the flipping power source is a servo motor, which facilitates precise control of the flipping angle. Of course, in other embodiments, the flipping power source can also be a flipping cylinder, which limits the position after flipping by limiting the extreme position.
[0039] When a tilting mechanism is needed, the lifting cylinder 62 first extends, causing the connecting plate 63 and guide column 64 to descend. At this point, the distance between the two mounting plates 65 must be greater than the sides of the transport platform. The descent stops when the two tilting positioning pins 67 on the mounting plates 65 move to the sides of the transport platform 2. Then, the push cylinder controls the two adjacent mounting plates 65 to move closer together, with the positioning pins on one side of the mounting plate matching the holes on both sides of the transport platform 2. The lifting cylinder then retracts, causing the transport platform 2 to rise, preventing interference with the frame during tilting. When it reaches a certain height, the tilting power source 66 tilts, correspondingly causing the transport platform 2 to tilt synchronously. After tilting, the lifting cylinder 62 extends again. The tilted transport platform 2 is placed on the transmission chain 31, and finally, the mounting plates 65 on both sides are moved away from each other, completing the tilting control of the transport platform.
[0040] When the transport platform 2 moves to its respective workstation, its position needs to be determined; therefore, a positioning mechanism is also required. For example... Figure 5 As shown, the positioning structure includes a limiting cylinder 33 mounted on a frame with a transmission chain 51. The limiting cylinder 33 can move up and down relative to the frame, thus facilitating its contact with the end of the transport platform 2 when it rises, thereby stopping and limiting the transport platform. To prevent the transport platform 2 from retracting after being stopped, a positioning cylinder 34 is also mounted on the frame. A positioning pin 35 is connected to the output end of the positioning cylinder 34. The positioning pin 35 is vertically arranged and can pass through the positioning hole on the transport platform when it rises, thereby locking the transport platform.
[0041] The capacitors, after the second flip, need to return to the visual inspection station 15 for capacitor soldering quality inspection. Therefore, a conveying mechanism with switchable transport direction is provided between the visual inspection station 15 and the second flipping station 16. The conveying mechanism includes a recycling conveyor chain 51 that is flush with the height of the conveyor chain 31 and a slide table 52 located at the bottom of the recycling conveyor chain 51 and driving the overall movement of the recycling conveyor chain 51. The recycling conveyor chain 51 can rotate independently on the slide table 52. The recycling conveyor chain 51 facilitates the transfer of the transport table 2 from the upstream conveyor chain 31, enabling smooth transport between the two stations. Simultaneously, during the inspection process, relative movement between the transport table 2 and the recycling conveyor chain 51 is undesirable. Therefore, a positioning mechanism 54 is also provided at this station to position the transport table 2 in a specific location. This positioning mechanism has the same structure as the positioning mechanism on the conveyor chain and will not be repeated here. Of course, in other embodiments, only the slide table may be provided, without the recycling conveyor chain.
[0042] like Figure 5 and Figure 7As shown, to enable the sliding of the slide table 52, the frame also includes a slide base 53, which extends from the vision inspection station 15 to the second flipping station 16 along the transmission direction of the flexible component. To enable the movement of the slide table 52 relative to the slide base 53, a servo motor is also provided inside the slide table 52 to drive its movement relative to the slide base 53. Specifically, a lead screw structure is connected to the output shaft of the servo motor, and a nut structure or threaded hole that mates with the lead screw is provided on the slide base, thus forming a servo lead screw slide table controlled by the servo motor. Simultaneously, the servo motor allows for more precise motion control, facilitating the control of the capacitor's rated movement speed or intermittent movement during motion. Alternatively, in other embodiments, a gear can be provided on the output shaft of the servo motor, and a rack can be provided on the slide base to mesh with the gear. When the servo motor rotates, the meshing of the gear and rack causes the slide table to move relative to the slide base. In other embodiments, the servo motor can also be a stepper motor. Alternatively, in other implementations, the slide may be omitted, and instead, an electric actuator or hydraulic cylinder may be installed on the frame, with the output shaft of the electric actuator or hydraulic cylinder connected to the slide, thereby achieving linear motion directly through the electric actuator or hydraulic cylinder.
[0043] like Figure 6 and Figure 8As shown, to enable capacitor inspection at the visual inspection station 15, a visual inspection module is installed at the visual inspection station 15. The visual inspection module includes a camera 44 for convenient visual inspection. Since the transport table 2 has multiple capacitor placement holes, multiple capacitors can be transported at once. Therefore, the visual inspection module needs to be able to move relative to each capacitor to facilitate alignment with capacitors at different positions and to inspect different capacitors separately. A support frame 41 is installed at the visual inspection station 15. The support frame 41 is a portal frame with a crossbar. A lateral translation mechanism 42 and a lifting mechanism 43 that move perpendicular to the transport direction of the flexible transport component are installed on the crossbar. Specifically, the lateral translation mechanism 42 includes a guide rail fixedly mounted on the crossbar and a lifting mounting seat adapted to the guide rail and capable of driving the lifting mechanism 43 to move relative to the guide rail. A drive motor is installed inside the lifting mounting seat to drive the lifting mounting seat to move horizontally relative to the guide rail. The lifting mechanism 43 includes a vertical guide rod mounted on a lifting mounting base 46 and a vision mounting base 46 guided on the vertical guide rod. The vision mounting base 46 is used to mount the camera 44. The vision mounting base 46 also serves as the output end of the lifting mechanism 43. The lateral movement mechanism 42 and the lifting mechanism 43 enable the camera 44 to move laterally and rise and fall, facilitating the detection of specific capacitors. Of course, in other embodiments, the lifting mechanism may be omitted, in which case the vision detection module can only move laterally. Alternatively, in other embodiments, the lateral translation mechanism may be omitted, and a camera with higher resolution may be used, allowing the camera to detect all capacitors at once.
[0044] During inspection, the welding equipment may not always be placed in a well-lit location. However, sufficient lighting is required when using the visual inspection module. Therefore, the visual inspection module includes a camera 44 and supplementary lights 45. The supplementary light 45 has a spherical lampshade with an opening at its center. The camera 44 is positioned at the opening of the lampshade. During inspection, supplementary lighting is first provided by the supplementary light 45, and then the camera 44 is used for inspection when sufficient light is available. Alternatively, in other embodiments, multiple supplementary lights 45 can be used, spaced apart around the camera 44. Or, in other embodiments, supplementary lighting may not be necessary; instead, spotlights can be added within the factory to provide additional illumination.
[0045] like Figure 3 and Figure 5As shown, during transport, a flexible transmission component is used. This flexible transmission component is segmented, and each segment includes a parallel transmission chain 31. The transmission chain 31 slides against the bottom of the transport platform 2 to drive the platform 2 under frictional force. To limit the movement of the transport platform 2, the frame includes a boss 32 extending beyond the transmission chain 31 and located outside it. A limiting block 23 located inside the boss 32 is provided on the transport platform 2. The limiting blocks 23 are provided on both sides of the transport platform 2. The limiting blocks 23 can also contact the transmission chain 31, facilitating the transport of the platform 2 by friction. The limiting blocks 23 ensure good limiting before and after capacitor flipping. Of course, in other embodiments, a conveyor belt can be used instead of a transmission chain. Alternatively, in other embodiments, the boss on the frame can be omitted, and the limiting blocks can be placed inside or outside the two parallel transmission chains. Alternatively, a limiting block can be installed only on one side.
[0046] It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
