Description

Technical Field

[0001] This application relates to the field of insertion and removal testing technology, and in particular to an insertion and removal testing docking device for production lines. Background Technology

[0002] In the current online insertion and removal reliability testing of large-scale electronic or optoelectronic products, the "male-female" pairing method is generally adopted: the test device, which is the "female" head, is first loaded into the positioning tray, and then the assembly line conveyor sends the tray to the test station in sequence; when the tray reaches the test position, the test execution mechanism above drives the "male" head to press down, completing one insertion and removal cycle, thereby detecting key indicators such as insertion and removal force, contact resistance, and signal integrity.

[0003] However, during start-up, reversing, and high-speed operation, the conveyor system inevitably experiences repeatability errors of ±0.5 mm or even greater; simultaneously, there is a certain clearance between the pallet and the conveyor chain (belt). The combined effect of these two factors causes a slight deviation between the actual and theoretical coordinates of the conveyor head.

[0004] When the offset exceeds the limit that the male guide chamfer can compensate for (usually ≤0.2 mm), the rigidly pressed male cutting edge will first have a "misalignment-biting" effect with the edge of the female head shell, resulting in stress concentration. As it continues to move downward, the bending moment at the root of the male pin is amplified exponentially, eventually exceeding the material yield strength, causing the pin to bend or even break instantly, which seriously affects the insertion and extraction efficiency and test yield. Utility Model Content

[0005] To facilitate accurate insertion and removal during testing, improve insertion and removal efficiency, and extend equipment lifespan, this application provides a insertion and removal testing docking device for production lines.

[0006] The plug-in / plug-out testing and docking device for assembly lines provided in this application adopts the following technical solution: A plug-in / plug-out testing and mating device for an assembly line includes a female connector plate and a male connector plate, wherein: The female head docking plate is fixed on a tray on the assembly line conveyor mechanism. The female head docking plate is provided with a socket unit and multiple positioning rings. The male and female connector plates are arranged in parallel. The male connector plate is provided with a plug unit corresponding to the socket unit. The male connector plate moves closer to or away from the female connector plate through a driving unit. The male connector plate is provided with a guide positioning rod that engages with the positioning ring. The male connector plate and the drive unit move relative to each other along the vertical plane of the moving direction of the positioning rod via the adjustment unit.

[0007] Optionally, the guide positioning rod includes a rod body and a guide block, wherein: The guide block is located at the end of the rod away from the male connector plate. The guide block gradually converges outward along the axial direction of the rod, and the end away from the rod forms a protruding tip.

[0008] Optionally, the positioning ring has a guide surface at its entrance that surrounds the inner edge of its opening, and the guide surface gradually narrows in a funnel shape from the outer end of the opening inward.

[0009] Optionally, the male connector plate is provided with multiple adjustment holes. The adjustment unit includes an adjustment frame, an adjustment rod, and an adjustment sleeve, wherein: The adjustment mechanism is mounted on the drive unit; The adjustment rod is provided in multiple ways, one end of the adjustment rod is provided on the adjustment frame, and the adjustment rod and the adjustment hole are inserted into each other; The adjusting sleeve is coaxially mounted on the adjusting rod. A pair of clamping rings are coaxially mounted on the outer wall of the adjusting sleeve. The pair of clamping rings clamp the male head mating plate, and a certain gap is left between the adjusting sleeve and the inner wall of the adjusting hole.

[0010] Optionally, the adjustment unit further includes an adjustment spring, which is sleeved on the adjustment rod. One end of the adjustment spring contacts the adjustment frame, and the other end of the adjustment spring contacts the top of the clamping ring on the adjustment sleeve.

[0011] Optionally, the adjusting spring is initially in a compressed state.

[0012] Optionally, a proximity sensor is provided between the male connector plate and the female connector plate, and the proximity sensor is connected to the processor via a cable.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. The guide positioning rod and the trumpet-shaped guide surface of the positioning ring form a progressive guide. First, the inclined plane is used for coarse correction, and then the cylindrical surface is used for fine positioning. With the radial gap reserved by the adjusting sleeve and the adjusting hole, the male head mating plate can actively float in the horizontal plane and absorb the initial alignment error in real time. This significantly reduces the dependence on mechanical installation and pallet positioning accuracy, while improving the first-time docking success rate and test yield. 2. The pre-compressed adjusting spring forms an elastic suspension and buffer in the vertical direction. When there is a height difference in the tray or the drive unit overshoots, the spring is further compressed and absorbs the impact kinetic energy. At the same time, the proximity sensor monitors the distance in real time, and the processor limits the maximum downward pressure before the safety threshold is reached. In case of abnormality, the drive is stopped and an alarm is triggered immediately. This reduces the occurrence of probe bending, socket shell breakage or drive motor overload jamming caused by rigid impact, and extends the service life of the equipment. 3. Floating correction transforms the time required for high-precision mechanical positioning or manual fine-tuning into a parallel process of pressing down and self-adjusting simultaneously, shortening the single docking cycle; at the same time, the entire device can be assembled with ordinary machining precision, and only the wear-resistant bushing and spring of the adjusting sleeve need to be replaced later, resulting in low maintenance costs.

[0018] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0019] This application discloses a plug-in / plug-out testing and docking device for production lines.

[0020] A plug-in / plug-out testing and docking device for an assembly line includes a female docking plate 1 and a male docking plate 2 that cooperate with each other. The female docking plate 1 is fixed on a tray of the assembly line conveyor mechanism. The female docking plate 1 is provided with a socket unit 11 and multiple positioning rings 12 distributed around it. The male docking plate 2 is parallel to the female docking plate 1 and has plug units 21 installed on it, corresponding to the positions of the socket units 11. The male docking plate 2 is controlled by a drive unit and can move linearly towards or away from the female docking plate 1. To achieve precise docking, the male docking plate 2 is provided with a guide positioning rod 3. During the docking process, the guide positioning rod 3 is first inserted into the positioning rings 12 on the female docking plate 1 for positioning, and then slightly moved in the vertical plane of the direction of movement of the positioning rod by an additional adjustment unit 4. In the embodiments of this application, the drive unit is a cylinder, but it can also be a lead screw module or other linear drive mechanisms.

[0021] During the process of the guide positioning rod 3 being fully inserted into the positioning ring 12, the entire male connector plate 2 can achieve slight adaptive floating in the vertical plane of the positioning rod's movement direction with the help of the adjustment unit 4. This floating mechanism can actively compensate for the alignment error between the male connector plate 2 and the female connector plate 1, thereby ensuring that the socket unit 11 and the insert unit 21 on both are accurately connected.

[0022] The guide positioning rod 3 mainly consists of a rod body 31 and a guide block 32 disposed at its end. One end of the rod body 31 is fixedly installed on the surface of the male connector plate 2 facing the female connector plate 1. The guide block 32 is located at the end of the rod body 31 away from the male connector plate 2, and its shape gradually converges outward along the axis of the rod body 31, finally forming a protruding tip at the end away from the rod body 31. The positioning ring 12 that cooperates with it has a guide surface around its inner edge at its entrance. This guide surface gradually converges inward in a trumpet shape from the outer end of the positioning ring 12 opening to form a two-stage guiding system.

[0023] When the male connector plate 2 is pressed down, the protruding tip of the guide block 32 first contacts the female connector plate 1. The tip of the guide block 32 first contacts the trumpet-shaped guide surface of the inlet of the positioning ring 12. Under the guiding action of the inclined surfaces of the two, the male connector plate 2 is forced to produce a slight horizontal float, achieving initial correction. As the guide block 32 goes further in, the rod 31 finally engages with the inner hole of the positioning ring 12, limiting the horizontal float to a very small range, thereby achieving the final precise positioning of the male connector plate 2 and the female connector plate 1.

[0024] This reduces the initial positioning accuracy requirements of the male connector plate 2 and the female connector plate 1, and also reduces the possibility of equipment jamming or damage caused by hard collisions, thereby improving the accuracy, efficiency and service life of the insertion and removal.

[0025] Multiple adjustment holes 22 are provided on the male connector plate 2. The adjustment unit 4 mainly consists of an adjustment frame 41, adjustment rods 42, and adjustment sleeves 43. The adjustment frame 41 is mounted on the drive unit. One end of each of the multiple adjustment rods 42 is fixed to the adjustment frame 41, and the other end is inserted into the adjustment holes 22 on the male connector plate 2. Each adjustment rod 42 is coaxially fitted with an adjustment sleeve 43. A pair of clamping rings 431 are coaxially provided on the outer wall of the adjustment sleeve 43. The male connector plate 2 is clamped and fixed by the pair of clamping rings 431. A specific radial gap is maintained between the outer wall of the adjustment sleeve 43 and the inner wall of the adjustment hole 22.

[0026] The adjusting rod 42 and the adjusting frame 41 form the main transmission frame, which is responsible for transmitting the downward movement of the drive unit to the male connector plate 2. The fit clearance between the adjusting sleeve 43 and the adjusting hole 22 provides the necessary movement space for the male connector plate 2 to make slight adaptive floating in the horizontal plane.

[0027] The drive unit pushes the male connector plate 2 downwards via the adjusting frame 41 and adjusting rod 42. During the correction process of the guide positioning rod 3 and positioning ring 12, if there is a horizontal deviation, the male connector plate 2 can make a slight radial movement relative to the fixed adjusting rod 42 within the gap range between the adjusting hole 22 and the adjusting sleeve 43, thereby achieving position self-correction. The clamping ring 431 ensures a tight connection between the male connector plate 2 and the adjusting sleeve 43, preventing them from loosening in the vertical or rotational direction and ensuring the stability of the floating process.

[0028] The adjusting unit 4 also includes an adjusting spring 44. The adjusting spring 44 is sleeved on the adjusting rod 42, with one end in contact with the adjusting frame 41 and the other end in contact with the top of the clamping ring 431 on the adjusting sleeve 43. The adjusting spring 44 is in a pre-compressed state after the device is assembled.

[0029] The pre-compressed adjusting spring 44 provides axial elastic force to the adjusting sleeve 43 to ensure that the male connector plate 2 can be stably suspended on the drive unit through the adjusting sleeve 43 in the non-connected state, maintaining a certain initial position; while during the connection process, it acts as a buffer and reset element, allowing the male connector plate 2 to undergo slight axial floating under the spring force, thereby absorbing vertical assembly errors or impacts, effectively preventing component damage caused by instantaneous overload, and further ensuring test yield and equipment life.

[0030] A proximity sensor 5 is installed between the male connector plate 2 and the female connector plate 1. The proximity sensor 5 is electrically connected to a processor via a cable.

[0031] The relative position or distance between the male connector plate 2 and the female connector plate 1 is monitored in real time by proximity sensor 5. The collected status signals are transmitted to the processor via cable. The processor, as the control center, judges and processes the signals according to preset logic, thereby realizing intelligent monitoring and safe intervention of the entire docking process.

[0032] As the drive unit moves the male connector plate 2 downwards, the proximity sensor 5 continuously detects changes in the distance between itself and the female connector plate 1. When the distance reaches a preset threshold, the sensor changes state and immediately sends a signal to the processor, which can then determine whether the docking process is in the correct stage. Before confirming successful proximity, the maximum downward pressure of the drive unit is limited; if the sensor does not detect a correct signal, the drive unit immediately stops and an alarm is triggered to prevent collision damage caused by misoperation.

[0033] The implementation principle of the plug-in / plug-out testing and docking device for a production line according to this application embodiment is as follows: The drive unit suspends and pushes the male connector plate 2 downward as a whole through the adjustment frame 41, adjustment rod 42, adjustment sleeve 43 and clamping ring 431. The pre-compressed adjustment spring 44 maintains the initial position of the male connector plate 2 in the non-connection state and provides vertical buffering capability. During the downward movement, the proximity sensor 5 monitors the distance between the male connector plate 2 and the female connector plate 1 fixed on the tray in real time. Once the preset threshold is reached, a signal is sent to the processor. The processor limits the maximum downward pressure accordingly and immediately stops the drive and alarms in case of abnormality. At the same time, the guide positioning... The guide block 32, which gradually converges at the end of the rod 3 and has a pointed tip, first contacts the flared guide surface at the inlet of the positioning ring 12 of the female head docking plate 1. Under the guidance of the two inclined surfaces, the male head docking plate 2 is forced to generate a small adaptive float in the horizontal plane by utilizing the radial gap between the outer wall of the adjusting sleeve 43 and the inner wall of the adjusting hole 22, thus completing the initial correction. Subsequently, the rod body 31 and the inner hole of the positioning ring 12 are precisely matched to limit the horizontal float to a very small range, thereby achieving precise docking between the socket unit 11 and the insert unit 21. Throughout the process, the floating mechanism continuously compensates for the alignment error, and the spring absorbs the vertical impact, ensuring accurate and efficient insertion and removal and avoiding damage from hard collisions.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
