Description

Technical Field

[0001] This invention relates to the field of electric vehicle manufacturing technology, and in particular to a full-process performance testing device for automotive electronic components. Background Technology

[0002] With the rapid development of intelligent and electric vehicles, the types, complexity, and reliability requirements of automotive electronic components are increasing daily. These components, such as engine control units (ECUs), various sensors, bus modules, and battery management systems (BMS), must undergo rigorous full-process performance testing before being installed in vehicles. This includes, but is not limited to, electrical performance testing, functional verification, and environmental reliability testing (such as high and low temperatures, humidity, and vibration) to ensure that they meet stringent automotive standards.

[0003] In the existing technology, most of the testing equipment integrated into the electronic component processing production line still relies on semi-automatic manual testing. The electronic components are moved from the production line to the testing equipment by the operator, the testing equipment is started for testing, and then the components are put back on the production line. This method is not only inefficient, but also has low overall testing efficiency due to the large number of testing items for electronic components.

[0004] Therefore, this invention proposes a full-process performance testing device for automotive electronic components. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a full-process performance testing device for automotive electronic components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A full-process performance testing equipment for automotive electronic components includes a frame and multiple functional testing units. A ring conveyor unit is provided on the top of the frame. Multiple follow-up fixing units for fixing electronic components are connected to the moving end of the ring conveyor unit. The functional testing units are located inside the ring conveyor unit. Each functional testing unit has different testing items. At the same time, each functional testing unit is provided with a lifting unit for lifting the follow-up fixing units. The follower fixing unit includes a follower plate that is driven to the moving end of the annular conveyor unit and a lifting plate that is fitted to the top of the follower plate through a fitting component. The top of the lifting plate is fixed with a follower fixing unit for fixing electronic components. The fitting components include a sleeve fixed to the top of the follower plate and a rod fixed to the lifting plate and insertable into the inner wall of the sleeve. The lifting unit includes a lifting cylinder fixed to the ground and a lifting rod connected to the lifting cylinder via a "Z"-shaped arm and a buffer protection component. The bottom of the lifting plate is fixed with a coupling sleeve with an opening on one side.

[0007] Preferably, the inner wall of the lifting rod is symmetrically connected to two sliding plates, and a wedge block with a single-sided inclined surface is fixed on the other side of the sliding plate. The inner wall of the coupling sleeve forms a groove with a bottom opening that cooperates with the wedge block. A spring is fastened to the opposite side of the two sliding plates.

[0008] Furthermore: the buffer protection component includes a second spring and a buffer frame. The inner wall of the buffer frame is provided with a guide groove. The lifting rod is slidably connected to the guide groove through a limiting post fixed on its outer wall. One end of the second spring is fastened to the inner wall of the buffer frame, and the other end of the second spring is fastened to the side wall of the lifting rod.

[0009] Based on the aforementioned scheme: the bottom curvature of the guide groove is less than the top curvature.

[0010] A preferred embodiment of the aforementioned solution is that the functional testing unit includes a bracket and a testing box fixed to the lower top surface of the bracket. The testing box contains a testing device for testing electronic components, and the outer wall of the testing box is equipped with a control panel that is connected to the testing device.

[0011] As a further embodiment of the present invention: the annular conveying unit includes an outer limiting frame and an inner limiting frame, both of which are fixed to the top outer wall of the frame by bolts. An outer fixed chain is fixed to the inner wall of the outer limiting frame, and an inner movable chain is provided on the outer side of the inner limiting frame.

[0012] Meanwhile, the inner movable chain and the outer fixed chain frame are meshed with multiple driven sprockets on opposite sides. The inner wall of the driven sprocket is rotatably connected to the same shaft II, and the top of the shaft II is rotatably connected to the bottom outer wall of the follower plate.

[0013] As a preferred embodiment of the present invention, a plurality of drive sprockets are rotatably connected to the bottom outer wall of the frame, and the drive sprockets mesh with the inner side of the inner movable chain.

[0014] Meanwhile, one or more of the inner limit frames are provided with an electric motor for driving them on the other side.

[0015] As a preferred embodiment of the present invention: both sides of the follower plate are rotatably connected to limit rollers via a shaft, and the two limit rollers are respectively movably limited and fitted to the inner walls of the outer limit frame and the inner limit frame.

[0016] The beneficial effects of this invention are as follows: 1. This invention, based on the ring conveying unit and the setting of multiple functional testing units, can achieve full-process testing according to the types of testing items for electronic components. In addition, based on the ring conveying of the functional testing units, it can reserve loading and unloading stations, so that the testing process, the conveying process, and the loading and unloading process can be carried out independently and crosswise, thereby ensuring testing efficiency.

[0017] 2. In this invention, by setting a slot and a wedge, with the bottom of the slot being open, when engaged, the inclined surface of the wedge is limited by the coupling sleeve and retracts into the interior of the lifting rod until the lifting rod and the coupling sleeve are fully engaged. The wedge is then engaged with the slot by the elastic force of spring one, thereby achieving planar movement locking of the lifting rod and the coupling sleeve, increasing safety. After the test is completed, the wedge can be disengaged from the bottom of the slot, completing the disengagement of the lifting rod and the coupling sleeve.

[0018] 3. The present invention, by setting a buffer protection component, can, on the one hand, utilize the lateral movement of the lifting rod in conjunction with the tension of the second spring to achieve impact buffering and increase reliability. On the other hand, since the guide groove is set with an inclined curve, the lifting rod will also move longitudinally when it moves laterally, so that the mating parts can gradually separate during the buffering process, blocking the lateral driving force of the lifting rod. At the same time, the weight of the entire follow-up fixing unit itself can also be used to achieve buffering, further increasing reliability.

[0019] 4. The present invention achieves circular conveying by setting the circular conveying unit based on the driving of the outer fixed chain frame, driven sprocket, and inner movable chain, and the limiting of the outer limit frame, inner limit frame, and limiting roller. Thus, it can set the driving of any path under certain conditions according to the shape of the outer limit frame and inner limit frame, thereby adapting to different parts production lines and factory space layouts.

[0022] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example

[0024] A full-process performance testing device for automotive electronic components, such as Figures 1-10As shown, the device includes a frame 1 and multiple functional testing units 5. A ring conveying unit 4 is provided on the top of the frame 1. Multiple follow-up fixing units 2 for fixing electronic components are connected to the moving end of the ring conveying unit 4. The functional testing units 5 are located inside the ring conveying unit 4. Each functional testing unit 5 has a different testing item. At the same time, each functional testing unit 5 is provided with a lifting unit 3 for lifting the follow-up fixing unit 2.

[0025] The follower fixing unit 2 includes a follower plate 13 that is driven to the moving end of the annular conveying unit 4 and a lifting plate 11 that is fitted to the top of the follower plate 13 through a fitting part 10. The top of the lifting plate 11 is fixed with the follower fixing unit 2 for fixing electronic components.

[0026] The fitting component 10 includes a sleeve 23 fixed to the top of the follower plate 13 and a rod 22 fixed to the lifting plate 11 and insertable into the inner wall of the sleeve 23.

[0027] The lifting unit 3 includes a lifting cylinder 6 fixed to the ground and a lifting rod 8 connected to the lifting cylinder 6 via a "Z"-shaped arm and a buffer protection component 7. The bottom of the lifting plate 11 is fixed with a coupling sleeve 9 with an opening on one side.

[0028] In this embodiment, the specific type of the fixing unit 12 is not limited. It can independently select the fixing fixture according to the type of electronic component to be fixed, with the aim of stably fixing the electronic component. Since it is a conventional method for those skilled in the art, this embodiment has not made any creative effort on it, so it will not be described in detail.

[0029] Meanwhile, in this embodiment, the types of multiple functional detection units 5 are not limited. They can be set according to the detection items of electronic components, such as including but not limited to electrical performance testing, functional verification, and environmental reliability testing - such as high and low temperature, damp heat, vibration, etc. Since each of them is in the prior art and is a mature technology, this embodiment only applies them functionally and does not make any creative effort, so it will not be described in detail.

[0030] When in use, electronic components can be fixed on the fixed unit 12. As the annular conveying unit 4 conveys, the electronic components are conveyed until they reach the position of the function detection unit 5. At this time, the lifting rod 8 is inserted into the inside of the coupling sleeve 9 from the opening of the coupling sleeve 9. Then the lifting cylinder 6 extends, which drives the entire follower fixed unit 2 to rise to the bottom detection position of the function detection unit 5. Then the function detection unit 5 performs detection. After the detection is completed, the lifting cylinder 6 descends, and the follower fixed unit 2 descends as a whole under gravity. Then, the lifting plate 11 and the follower plate 13 are recoupled by the cooperation of the mating parts 10 to complete the continued conveying.

[0031] This invention, based on the circular conveying unit 4 and the setting of multiple functional detection units 5, can realize full-process detection according to the detection items of electronic components. In addition, based on the circular conveying of the functional detection units 5, it can reserve loading and unloading stations, so that the detection process, conveying process and loading and unloading process can be carried out independently and crosswise, thereby ensuring detection efficiency.

[0032] To address stability issues; such as Figure 4 As shown, the inner wall of the lifting rod 8 is symmetrically connected to two sliding plates 15. A wedge block 17 with a single-sided inclined surface is fixed on the other side of the sliding plate 15. The inner wall of the coupling sleeve 9 forms a slot 16 with a bottom opening that cooperates with the wedge block 17. A spring 14 is fastened to the opposite side of the two sliding plates 15.

[0033] Since the coupling sleeve 9 is open on one side, the lifting rod 8 can also move in one direction relative to the coupling sleeve 9. Therefore, there is a risk of slippage after lifting. This device is designed with a slot 16 and a wedge 17. The bottom of the slot 16 is open. When engaged, the inclined surface of the wedge 17 is limited by the coupling sleeve 9 and retracts into the interior of the lifting rod 8 until the lifting rod 8 and the coupling sleeve 9 are fully engaged. The wedge 17 is engaged with the slot 16 by the elastic force of the spring 14, thereby locking the planar movement of the lifting rod 8 and the coupling sleeve 9, increasing safety. After the test is completed, the wedge 17 can be disengaged from the bottom of the slot 16, completing the disengagement of the lifting rod 8 and the coupling sleeve 9.

[0034] To solve the buffering problem; such as Figure 2 , 5 As shown, the buffer protection component 7 includes a second spring 18 and a buffer frame 20. The inner wall of the buffer frame 20 is provided with a guide groove 21. The lifting rod 8 is slidably connected to the guide groove 21 through a limiting post 19 fixed on its outer wall. One end of the second spring 18 is fastened to the inner wall of the buffer frame 20, and the other end of the second spring 18 is fastened to the side wall of the lifting rod 8.

[0035] The bottom curvature of the guide groove 21 is less than the top curvature.

[0036] When the lifting rod 8 and the coupling sleeve 9 reach the mating position, the lifting rod 8 and the coupling sleeve 9 will experience impact along the conveying direction. If the lifting rod 8 cannot move laterally, the parts will be damaged due to repeated impacts. By setting the buffer protection component 7, on the one hand, the lateral movement of the lifting rod 8 can be combined with the tension of the spring 18 to achieve impact buffering and increase reliability. On the other hand, since the guide groove 21 is set with an inclined curve, the lifting rod 8 will also move longitudinally when it moves laterally. Thus, during the buffering process, the mating component 10 can be gradually separated, blocking the lateral driving force of the lifting rod 8. At the same time, the weight of the entire follower fixing unit 2 itself can be used to achieve buffering, further increasing reliability.

[0037] To solve the detection problem; such as Figure 10 As shown, the functional testing unit 5 includes a bracket 33 and a testing box 34 fixed to the top and lower surface of the bracket 33. The testing box 34 is equipped with a testing device for testing electronic components, and the outer wall of the testing box 34 is equipped with a control panel 35 that is connected to the testing device.

[0038] In this embodiment, electronic components can be fixed to the fixing unit 12. As the annular conveying unit 4 transports the components, they are conveyed until they reach the position of the functional testing unit 5. At this point, the lifting rod 8 engages with the inside of the coupling sleeve 9 from its opening. Since the coupling sleeve 9 is only open on one side, the lifting rod 8 can still move in one direction relative to the coupling sleeve 9, posing a risk of slippage after lifting. This device addresses this by setting a slot 16 and a wedge 17, with the bottom of the slot 16 being open. When engaged, the inclined surface of the wedge 17 is limited by the coupling sleeve 9 and retracts into the lifting rod 8 until the lifting rod 8 and coupling sleeve 9 are fully engaged. The wedge 17 then engages with the slot 16 under the elastic force of the spring 14, thus locking the planar movement of the lifting rod 8 and coupling sleeve 9. Subsequently, the lifting cylinder 6 extends, driving the entire follow-up fixing unit 2 to rise to the testing position inside the lifting unit 36. Then, the detection device inside the detection box 34 performs the detection. After the detection is completed, the lifting cylinder 6 descends, and the follower fixing unit 2 descends as a whole under gravity. Then, the lifting plate 11 and the follower plate 13 are recoupled by the cooperation of the mating part 10 to complete the continued conveying. At the same time, when the lifting rod 8 and the coupling sleeve 9 reach the mating position, the lifting rod 8 and the coupling sleeve 9 will have an impact along the conveying direction. If the lifting rod 8 cannot move laterally, the parts will be damaged due to multiple impacts. By setting the buffer protection part 7, on the one hand, the lateral movement of the lifting rod 8 can be used in conjunction with the tension of the spring 18 to achieve impact buffering and increase reliability. On the other hand, since the guide groove 21 is set with an inclined curve, the lifting rod 8 will also move longitudinally when it moves laterally. Thus, during the buffering process, the mating part 10 can be gradually separated to block the lateral driving force of the lifting rod 8. At the same time, the weight of the entire follower fixing unit 2 can also be used to achieve buffering. Example

[0039] A full-process performance testing device for automotive electronic components, such as Figures 1-10As shown, in order to solve the conveying problem, this embodiment makes the following improvements based on embodiment 1: The annular conveying unit 4 includes an outer limiting frame 26 and an inner limiting frame 31. The outer limiting frame 26 and the inner limiting frame 31 are both fixed to the top outer wall of the frame 1 by bolts. An outer fixed chain frame 27 is fixed to the inner wall of the outer limiting frame 26. An inner movable chain 30 is provided on the outer side of the inner limiting frame 31. Multiple driven sprockets 28 are meshed on the opposite side of the inner movable chain 30 and the outer fixed chain frame 27. The inner wall of the driven sprocket 28 is rotatably connected to the same shaft 29. The top of the shaft 29 is rotatably connected to the bottom outer wall of the follower plate 13.

[0040] The bottom outer wall of the frame 1 is rotatably connected to a plurality of drive sprockets 32, which mesh with the inner side of the inner movable chain 30, and one or more of the inner limit frames 31 are provided with an electric motor for driving it on the other side.

[0041] Both sides of the follower plate 13 are rotatably connected to limit rollers 25 via shaft 24. The two limit rollers 25 are respectively movable and limited to the inner walls of the outer limit frame 26 and the inner limit frame 31.

[0042] In this embodiment, when the motor drives the inner limiting frame 31 to rotate, it drives the inner movable chain 30 to move. Since the driven sprocket 28 is engaged with both the outer fixed chain frame 27 and the inner movable chain 30, and the outer fixed chain frame 27 is fixed, the driven sprocket 28 will rotate while moving along the path between the outer fixed chain frame 27 and the inner movable chain 30. At the same time, since the limiting roller 25 is limited by the outer limiting frame 26 and the inner limiting frame 31, the driven sprocket 28 can be used to move along the path between the outer fixed chain frame 27 and the inner movable chain 30 to drive the follower plate 13 to slide along its path, thereby achieving the purpose of circular conveying.

[0043] This device achieves circular conveying by setting the annular conveying unit 4 to be driven by the outer fixed chain frame 27, driven sprocket 28, and inner movable chain 30, and limited by the outer limit frame 26, inner limit frame 31, and limit roller 25. Thus, it can set the drive for any path under certain conditions according to the shape of the outer limit frame 26 and inner limit frame 31, thereby adapting to different parts production lines and factory space layouts.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
