Description

Technical Field

[0001] This utility model relates to the field of electronic testing equipment technology, and in particular to a flipping device for aging testing of optoelectronic products. Background Technology

[0002] Optoelectronic product testing equipment is a professional instrument used to test the optical, electrical, and environmental performance of optoelectronic products such as LEDs, displays, and optical modules. Its core function is to ensure that product performance meets standards and quality is stable. Common types include optical testing equipment such as spectrometers, integrating spheres, and luminance meters; electrical testing equipment such as DC power supplies, electronic loads, and oscilloscopes; and environmental reliability testing equipment such as high and low temperature chambers and vibration testing machines. These are widely used in consumer electronics, lighting, communications, automotive electronics, and other fields. Therefore, there is a particular need for a flipping device for aging tests of optoelectronic products.

[0003] Chinese patent CN219590434U, published on August 25, 2023, discloses an electronic product aging test device. It adopts a heating fan structure to raise the temperature inside the aging machine body, thereby testing the performance of electronic products at high temperatures and achieving the purpose of testing their aging degree. At the same time, it adopts a cooling fan structure to blow out cold air, which quickly cools the electronic products and tests their resistance to temperature difference. However, this electronic product aging test device can only fix the product under test in a single plane or at a single angle. It cannot flexibly simulate the diverse installation postures that electronic products may face in actual use, such as the different installation angles commonly used in daily applications, such as wall-mounted, vertical, and embedded. This results in a large deviation between the test environment and the actual use scenario, making it difficult to fully reflect the aging characteristics of the product under real use conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flipping device for aging testing of optoelectronic products, comprising a control cabinet, a workbench, and a display screen. A protective cover is fixedly connected to one side surface of the control cabinet, and a cabinet door is rotatably connected to one side surface of the protective cover. A caster wheel is fixedly connected to the side surface of the control cabinet away from the workbench. A fixing plate is fixedly connected to the side surface of the workbench away from the control cabinet. A groove is formed on the side surface of the fixing plate away from the control cabinet. A guide rail is fixedly connected to the side surface of the fixing plate away from the control cabinet, and a flipping mechanism is provided on the outer surface of the guide rail. The flipping mechanism includes a sliding seat and an electric cylinder. The sliding seat is slidably connected to the outer surface of the guide rail, and the electric cylinder is fixedly connected to the inner surface of the groove. A groove is formed on one side surface of the sliding seat, and a horizontal plate is fixedly connected to one side surface of the sliding seat. A connecting block is fixedly connected to the side surface of the horizontal plate near the guide rail, and a rotating component is fixedly connected to the side surface of the horizontal plate away from the guide rail. A rotating plate is rotatably connected to one side surface of the rotating component. A rectangular groove is formed on one side surface of the rotating plate, and a bidirectional threaded rod is rotatably connected to the inner surface of the rectangular groove. A clamping piece is threadedly connected to the outer surface of the bidirectional threaded rod, and a protruding strip is fixedly connected to one side surface of the clamping piece. A turntable is fixedly connected to one end of the bidirectional threaded rod, and a gripping rod is fixedly connected to one side surface of the turntable. A connecting rod is rotatably connected to one side surface of the rotating plate, and a support component is rotatably connected to one side surface of the connecting rod.

[0006] Preferably, the connecting rod and the support member are provided in two identical sizes and are symmetrically distributed along the horizontal central axis of the fixed plate. The end of the support member away from the connecting rod is fixedly connected to the side surface of the fixed plate near the electric cylinder.

[0007] Preferably, the clamping pieces are provided in two identical sizes and are symmetrically distributed along the transverse central axis of the bidirectional threaded rod. The cross-section of the clamping piece is T-shaped, and the outer wall dimension of the end of the clamping piece away from the convex strip is adapted to the inner wall dimension of the rectangular groove.

[0008] Preferably, the protrusions are provided in multiple sizes, and the outer wall size of the connecting block is adapted to the inner wall size of the groove.

[0009] Preferably, the guide rails are provided in two identical sizes and are symmetrically distributed along the horizontal central axis of the fixed plate, the sliding seats are provided in four identical sizes and are symmetrically distributed along the horizontal central axis of the fixed plate, and the inner wall size of the sliding groove is adapted to the outer wall size of the guide rail.

[0010] Preferably, there are two rotating components of the same size, which are symmetrically distributed along the horizontal central axis of the horizontal plate, and the cross-section of the rotating component is "L" shaped.

[0011] Preferably, the horizontal plate and the fixed plate are distributed parallel to each other along the vertical central axis of the connecting block, and four universal wheels of the same size are provided and are symmetrically distributed along the horizontal central axis of the control cabinet.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the linkage structure of electric cylinder drive, connecting rod and support, combined with two symmetrically distributed guide rails and four sliding seats, it can not only realize the smooth angle flipping of the rotating plate and product, but also precisely control the flipping angle and rate by adjusting the running speed and stroke of the electric cylinder, so as to meet the aging test needs of different optoelectronic products under diverse actual use angles and make up for the shortcomings of the single test angle of traditional equipment. 2. The design adopts a two-way threaded rod with a "T" shaped clamp. The clamp can move precisely along the rectangular groove, which can adapt to optoelectronic products of different sizes. At the same time, the multiple convex strips on the surface of the clamp greatly increase the friction with the product, effectively preventing the product from shifting or falling off during the flipping test, ensuring a stable and reliable test process.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6This utility model provides a technical solution: a flipping device for aging test of optoelectronic products, including a control cabinet 1, a workbench 2 and a display screen 3. A protective cover 4 is fixedly connected to one side surface of the control cabinet 1, and a cabinet door 5 is rotatably connected to one side surface of the protective cover 4. A caster wheel 6 is fixedly connected to the side surface of the control cabinet 1 away from the workbench 2. A fixing plate 7 is fixedly connected to the side surface of the workbench 2 away from the control cabinet 1. A groove 8 is opened on the side surface of the fixing plate 7 away from the control cabinet 1. A guide rail 9 is fixedly connected to the side surface of the fixing plate 7 away from the control cabinet 1. A flipping mechanism 10 is provided on the outer surface of the guide rail 9. The flipping mechanism 10 includes a sliding seat 1001 and an electric cylinder 1002. The sliding seat 1001 is slidably connected to the outer surface of the guide rail 9, and the electric cylinder 1002 is fixedly connected to the inner surface of the groove 8. A groove 1003 is formed on one side surface of the sliding seat 1001. A horizontal plate 1004 is fixedly connected to one side surface of the sliding seat 1001. A connecting block 1005 is fixedly connected to the side surface of the horizontal plate 1004 closest to the guide rail 9. A rotating component 1006 is fixedly connected to the side surface of the horizontal plate 1004 away from the guide rail 9. A rotating plate 1007 is rotatably connected to one side surface of the rotating component 1006. A rectangular groove 1008 is formed on one side surface of the rotating plate 1007. A bidirectional threaded rod 1009 is rotatably connected to the inner surface of the rectangular groove 1008. A clamping piece 1010 is threaded onto the outer surface of component 9. A protruding strip 1011 is fixedly connected to one side surface of the clamping piece 1010. A turntable 1012 is fixedly connected to one end of the bidirectional threaded rod 1009. A gripping rod 1013 is fixedly connected to one side surface of the turntable 1012. A connecting rod 1014 is rotatably connected to one side surface of the rotating plate 1007. A support member 1015 is rotatably connected to one side surface of the connecting rod 1014. The components include a sliding seat 1001, an electric cylinder 1002, a sliding groove 1003, a horizontal plate 1004, a connecting block 1005, a rotating component 1006, a rotating plate 1007, a rectangular groove 1008, a bidirectional threaded rod 1009, a clamping piece 1010, a protruding strip 1011, a turntable 1012, a gripping rod 1013, a connecting rod 1014, and a support member 1015. In this setup, after placing the optoelectronic product to be tested on the surface of the turntable 1007, hold the lever 1013 on the turntable 1012 and rotate the bidirectional threaded rod 1009. Because the clamping piece 1010 is threadedly connected to the bidirectional threaded rod 1009, and the end of the clamping piece 1010 away from the protrusion 1011 is adapted to the inner wall of the rectangular groove 1008, the rotation of the bidirectional threaded rod 1009 will cause the two clamping pieces 1010 to move relative to each other along the rectangular groove 1008 until the clamping pieces 1010 are in contact with the product surface. Multiple protrusions 1011 increase the friction between the clamping pieces 1010 and the product, ensuring the product is securely fixed. After the product is fixed, start the electric cylinder 1002 to push the connecting block 1005. Because the connecting block 1005 is fixedly connected to the horizontal plate 1004, and the horizontal plate 1004 is connected to the sliding block... The seat 1001 is fixedly connected and the sliding seat 1001 is slidably connected to the guide rail 9 through the slide groove 1003. The connecting block 1005 will drive the horizontal plate 1004 and the sliding seat 1001 to move stably along the guide rail 9. At the same time, when the horizontal plate 1004 moves, it will drive the rotating part 1006 and the rotating plate 1007 to move synchronously. One side of the rotating plate 1007 is rotatably connected to the support 1015 fixed on the fixed plate 7 through the connecting rod 1014. There are two connecting rods 1014 and two support 1015, which are symmetrically distributed. As the horizontal plate 1004 moves, the connecting rod 1014 will rotate around the support 1015 and push the rotating plate 1007 to rotate around the rotating part 1006, thereby realizing the angle flipping of the rotating plate 1007 and the fixed product, meeting the aging test requirements at different angles.

[0017] Furthermore, two connecting rods 1014 and support members 1015 of the same size are provided and are symmetrically distributed along the horizontal central axis of the fixed plate 7. The end of the support member 1015 away from the connecting rod 1014 is fixedly connected to the side surface of the fixed plate 7 near the electric cylinder 1002. Through the arrangement of the connecting rod 1014 and support member 1015, during use, the connecting rod 1014 and support member 1015 can provide symmetrical and balanced support and transmission force for the rotating plate 1007, avoiding problems such as tilting and shaking of the rotating plate 1007 due to uneven force during the flipping process, ensuring that the rotating plate 1007 and the fixed optoelectronic products always maintain a stable flipping state, and effectively reducing the risk of collision caused by unstable flipping of the products.

[0018] Furthermore, two clamping plates 1010 of the same size are provided and are symmetrically distributed along the transverse central axis of the bidirectional threaded rod 1009. The cross-section of the clamping plate 1010 is T-shaped. The outer wall dimension of the end of the clamping plate 1010 away from the protrusion 1011 is adapted to the inner wall dimension of the rectangular groove 1008. With the setting of the clamping plate 1010, during use, the two symmetrically distributed clamping plates 1010 can move towards the middle or separate to both sides synchronously under the drive of the bidirectional threaded rod 1009, so as to apply a balanced clamping force from both sides of the product and avoid product deformation due to excessive force on one side. It is especially suitable for the fixing requirements of thin and light optoelectronic products.

[0019] Furthermore, multiple protrusions 1011 of the same size are provided, and the outer wall size of the connecting block 1005 is adapted to the inner wall size of the groove 8. Through the provision of protrusions 1011, multiple protrusions 1011 can greatly increase the contact friction between the clamping piece 1010 and the surface of the optoelectronic product during use, making the clamping more stable.

[0020] Furthermore, the guide rails 9 are provided with two of the same size and are symmetrically distributed along the horizontal central axis of the fixed plate 7. The sliding seats 1001 are provided with four of the same size and are symmetrically distributed along the horizontal central axis of the fixed plate 7. The inner wall size of the slide groove 1003 is adapted to the outer wall size of the guide rail 9. Through the arrangement of the sliding seats 1001, slide groove 1003 and guide rails 9, the precise adaptation between the slide groove 1003 and the guide rail 9 can limit the movement trajectory of the sliding seats 1001 during use, ensuring that the sliding seats 1001 only move in a straight line along the guide rail 9, and avoiding deviation or jamming when the horizontal plate 1004 drives the rotating plate 1007 to move.

[0021] Furthermore, two rotating components 1006 of the same size are provided and are symmetrically distributed along the horizontal central axis of the horizontal plate 1004. The cross-section of the rotating component 1006 is "L" shaped. Through the arrangement of the rotating components 1006, the two symmetrical rotating components 1006 can provide balanced rotational support points for the rotating plate 1007 during use, ensuring that the rotating plate 1007 is subjected to consistent forces on both sides when it is flipped around the rotating component 1006, avoiding unilateral tilting or jamming of the rotating plate 1007, and making the flipping action smoother.

[0022] Furthermore, the horizontal plate 1004 and the fixed plate 7 are distributed parallel to each other along the vertical central axis of the connecting block 1005. Four casters 6 of the same size are provided and are symmetrically distributed along the horizontal central axis of the control cabinet 1. With the setting of the casters 6, the four symmetrically distributed casters 6 can evenly distribute the weight of the entire equipment during use, avoiding damage caused by overload of a single caster 6. At the same time, it ensures that the bottom of the equipment is balanced when placed, reducing the risk of tipping over due to the shift of the center of gravity, and ensuring the stability of the equipment and the safety of the operators during the testing process.

[0023] Working principle: After the optoelectronic product to be tested is placed on the surface of the turntable 1007, the grip bar 1013 on the turntable 1012 is held to rotate the bidirectional threaded rod 1009. Because the clamping piece 1010 is threadedly connected to the bidirectional threaded rod 1009 and the end of the clamping piece 1010 away from the protrusion 1011 is adapted to the inner wall of the rectangular groove 1008, the rotation of the bidirectional threaded rod 1009 will drive the two clamping pieces 1010 to move relative to each other along the rectangular groove 1008 until the clamping pieces 1010 are in contact with the product surface. The multiple protrusions 1011 can increase the friction between the clamping pieces 1010 and the product, ensuring that the product is fixed and stable. After the product is fixed, the electric cylinder 1002 is started. The output end of the electric cylinder 1002 pushes the connecting block 1005. Because the connecting block 1005 is fixedly connected to the horizontal plate 1004 and the horizontal plate 1004 is fixedly connected to the sliding seat 1001, and the product is fixedly connected to the horizontal plate 1004, the product is fixedly connected to the horizontal plate 1004 and the sliding seat 1001, the product is fixedly connected to the horizontal plate 1004 and the product is fixedly connected to the horizontal plate 1004 and the product is fixedly connected to the horizontal plate 1005, and the product is fixedly connected to the horizontal plate 1004 and the product is fixedly connected to the horizontal plate 1004 and the product is fixedly connected to the horizontal plate 1005, the product is fixedly connected to the horizontal plate 1004 and the product is fixedly connected to the horizontal plate 1004 and the product is fixedly connected to the horizontal plate 1005, and the product is fixedly connected to the horizontal plate 100 The sliding seat 1001 is slidably connected to the guide rail 9 via the sliding groove 1003. The connecting block 1005 drives the horizontal plate 1004 and the sliding seat 1001 to move stably along the guide rail 9. At the same time, when the horizontal plate 1004 moves, it drives the rotating component 1006 and the rotating plate 1007 to move synchronously. One side of the rotating plate 1007 is rotatably connected to the support component 1015 fixed on the fixed plate 7 via the connecting rod 1014. There are two connecting rods 1014 and two support components 1015, which are symmetrically distributed. As the horizontal plate 1004 moves, the connecting rod 1014 rotates around the support component 1015 and pushes the rotating plate 1007 to rotate around the rotating component 1006, thereby realizing the angle flipping of the rotating plate 1007 and the fixed product, meeting the aging test requirements at different angles. This completes the use process of a flipping device for aging test of optoelectronic products.
