Description

Technical Field

[0001] This application relates to the field of optoelectronic connector testing equipment technology, and in particular to an automatic testing device for optoelectronic sensors. Background Technology

[0002] In the production and testing of optoelectronic sensors and related electronic components, performance testing of electrical connectors (such as pins and sockets) is a crucial step in ensuring product quality. Current testing equipment for electrical connectors typically suffers from the following shortcomings: Insufficient testing accuracy: Traditional equipment relies on manual operation or simple mechanical structures, making it difficult to accurately control the pressure application process, resulting in large errors in the test results.

[0003] Limited applicability: Existing testing devices are mostly designed for a single type of electrical connector, making it difficult to flexibly adapt to testing requirements of different specifications (such as size, density, and socket depth), requiring frequent replacement of the entire set of equipment.

[0004] Low level of automation: Most equipment requires manual adjustment of position or application of pressure, which is inefficient and prone to deviation due to human operation.

[0005] Delayed pressure feedback: The lack of a real-time pressure monitoring mechanism makes it impossible to dynamically adjust the pressure parameters, resulting in a lack of controllability and repeatability in the testing process.

[0006] The aforementioned problems limit the efficiency and reliability of electrical connector testing, and there is an urgent need for an automated testing device that is structurally stable, easy to operate, and highly adaptable. Summary of the Invention

[0007] The purpose of this application is to provide an automatic testing device for photoelectric sensors to solve the above problems. Through modular design, automated control and real-time pressure monitoring, this application significantly improves the accuracy, efficiency and adaptability of electrical connector testing.

[0008] This application achieves the above objectives through the following technical solutions: An automatic detection device for a photoelectric sensor includes: a bracket and a base, the bracket being fixed to the top of the base and capable of providing support; a disassembly / assembly base connected to a lifting drive structure to allow the disassembly / assembly base to lift and press against an electrical connector; a pressure mold detachably connected to the disassembly / assembly base, with a pin adapted to the electrical connector at its bottom; a support base fixedly connected to the bracket; a pressure-bearing base with a sliding column fixedly connected to its bottom, the sliding column passing through the support base and slidingly engaging with the support base; an electrical connector mold base detachably connected to the pressure-bearing base, located below the pressure mold, and with a receiving cavity adapted to the shape of the electrical connector at its top for stably supporting the electrical connector; and a pressure sensor disposed between the pressure-bearing base and the support base, configured to detect the pressure applied to the pressure-bearing base.

[0009] In some embodiments, the lifting drive structure includes: a motor, fixedly mounted on the top of the bracket; a screw, the end of which is fixedly connected to the output end of the motor; a screw sleeve, sleeved on the screw and screwed to the screw; a guide support, fixedly connected to the bracket; and a guide sleeve, fixedly connected to the guide support, and having a through hole adapted to the screw sleeve, wherein the screw sleeve slides in cooperation with the through hole.

[0010] In some embodiments, the mounting / dismounting seat has a receiving cavity for accommodating the pressure-applying mold, the top of the mounting / dismounting seat is fastened to the pressure-applying mold by fasteners, and the pressure-receiving seat is constructed with a receiving cavity capable of accommodating the electrical connector mold base, the electrical connector mold base being movably connected to the pressure-receiving seat.

[0011] In some embodiments, a bearing support is fixedly connected to a bracket; a bearing housing is fixedly mounted on the bearing support and can be sleeved on a threaded rod.

[0012] In some embodiments, the threaded sleeve is prismatic.

[0013] Compared to existing technologies, this application features a detachable mold: the pressure mold and the mounting / dismounting base, as well as the electrical connector mold base and the pressure-receiving base, are all detachably connected, supporting quick replacement of different specifications of sockets and electrical connector receiving cavities, adapting to various models of electrical connectors without replacing the entire machine. It has a standardized interface: modular assembly is achieved through fasteners (such as bolts and screws), reducing maintenance costs and improving equipment versatility. It features a lifting drive structure, where a motor drives the screw to rotate, and the screw sleeve rises and falls under the constraint of a linear guide sleeve, ensuring linear stability during the pressure application process and preventing deviation or jamming. A pressure sensor is integrated, embedded between the pressure-receiving base and the support base, directly detecting the mechanical properties of the pin under pressure (such as bending and tilting), and feeding back to the control system to dynamically adjust the pressure parameters, ensuring test consistency.

[0016] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0017] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0018] like Figure 1-2 As shown, an automatic detection device for a photoelectric sensor includes: a bracket 1 and a base 2, the bracket 1 being fixed to the top of the base 2 to provide support; a disassembly / assembly seat 3 connected to a lifting drive structure to allow the disassembly / assembly seat 3 to lift and press against an electrical connector; a pressure mold 4 detachably connected to the disassembly / assembly seat 3, with a pin adapted to the electrical connector at its bottom; a support seat 9 fixedly connected to the bracket 1; a pressure-bearing seat 6 with a sliding column 10 fixedly connected to its bottom, the sliding column 10 passing through the support seat 9 and slidingly engaging with the support seat 9; an electrical connector mold seat 7 detachably connected to the pressure-bearing seat 6, located below the pressure mold 4, and with a receiving cavity 8 adapted to the shape of the electrical connector at its top for stable support of the electrical connector; and a pressure sensor 11 disposed between the pressure-bearing seat 6 and the support seat 9, configured to detect the pressure on the pressure-bearing seat 6.

[0019] In this embodiment, the bracket 1 has a frame structure, which can improve stable support. The lifting and disassembly base 3 is driven to rise and fall by the lifting drive structure, so that the pressure mold 4 rises and falls accordingly. Then, the pin of the electrical connector can be inserted into the socket 5. The diameter of the socket 5 is larger than that of the pin of the electrical connector. Further pressure is applied to bend or deform the pin. At this time, the pressure sensor 11 detects the pressure, and thus the pressure resistance of the pin is known. At the same time, the detachable pressure mold 4 and electrical connector mold base 7 can be easily replaced, and the socket 5 of different sizes, densities and depths can be replaced. The electrical connector receiving cavity 8 can also be replaced to adapt to different electrical connectors. Therefore, different models of electrical connectors can be detected. The sliding column 10 can support the short-range lifting and lowering of the pressure base 6 so that the pressure is transmitted to the pressure sensor 11, and the pressure sensor 11 detects the pressure. At the same time, the controller can preset the threshold according to the parameters of the pressure sensor 11 to avoid overload of the motor 12.

[0020] In some embodiments, the lifting drive structure includes: a motor 12, fixedly mounted on the top of the bracket 1; a screw 13, the end of which is fixedly connected to the output end of the motor 12; a screw sleeve 14, sleeved on the screw 13 and screwed to the screw 13; a guide support 15, fixedly connected to the bracket 1; and a guide sleeve 16, fixedly connected to the guide support 15, and having a through hole adapted to the screw sleeve 14, wherein the screw sleeve 14 is slidably engaged with the through hole.

[0021] In this embodiment, the threaded sleeve 14 is screwed to the screw 13. When the screw 13 rotates, the threaded sleeve 14 can rise and fall. Simultaneously, guided by the guide sleeve 16, the linear rise and fall of the threaded sleeve 14 is ensured, so as to apply pressure to the electrical connector through the pressure mold 4.

[0022] In some embodiments, the disassembly base 3 has a receiving cavity for accommodating the pressure mold 4, and the top of the disassembly base 3 is fastened to the pressure mold 4 by fasteners 18. The pressure receiving base 6 is constructed with a receiving cavity capable of accommodating the electrical connector mold base 7, and the electrical connector mold base 7 is movably connected to the pressure receiving base 6.

[0023] In this embodiment, the pressure mold 4 is installed in the receiving cavity of the disassembly base 3. The pressure mold 4 can be disassembled and assembled by the fastener 18 for easy replacement. In some embodiments, the fastener 18 is a bolt, screw, etc. The receiving cavity on the pressure seat 6 is used to accommodate the electrical connector mold base 7. The electrical connector mold base 7 is movably connected to the pressure seat 6, and the electrical connector mold base 7 can be directly disassembled and assembled for easy replacement.

[0024] In some embodiments, the bearing support 17 is fixedly connected to the bracket 1; the bearing seat 19 is fixedly installed on the bearing support 17 and can be sleeved on the screw 13.

[0025] In this embodiment, the bearing support 17 is fixedly connected to the bracket 1 to improve the support performance. At the same time, the bearing seat 19 is sleeved on the screw 13, which can further increase the axial load of the screw 13, so that when the screw 13 drives the screw sleeve 14 to descend to apply pressure, the screw 13 remains stable.

[0026] In some embodiments, the threaded sleeve 14 is prismatic, which allows the threaded sleeve 14 to slide and rise on the guide sleeve 16 when it rises and falls, while the guide sleeve 16 guides the threaded sleeve 14 to prevent the threaded sleeve 14 from rotating.

[0027] In the above structure, the electrical connector to be tested is placed in the electrical connector receiving cavity 8. The electrical connector receiving cavity 8 is adapted to the shape of the electrical connector, so it can stably support the electrical connector and prevent the electrical connector from shifting. The motor 12 starts to drive the screw 13 to rotate, the screw sleeve 14 to rise and fall, and then the disassembly and assembly seat 3 to rise and fall, driving the pressure mold 4 to fall. The pin of the electrical connector is inserted into the socket 5. When it is inserted to the bottom of the socket 5, the pressure mold 4 continues to fall to apply pressure to the electrical connector. At this time, the pressure sensor 11 detects the pressure. When the pin is bent or tilted, the pressure is stopped, the motor 12 starts to reverse and reset, and the pressure parameters are recorded to test the pin performance of the electrical connector.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this application. 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 merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
