Description

Technical Field

[0001] This utility model relates to the field of automation of loading and unloading aging boards, and in particular to a loading and unloading mechanism and equipment for a flip-top socket. Background Technology

[0002] In the aging test of chips and semiconductor devices, the flip-top socket serves as a crucial interface connecting the device under test (DUT) to the aging board, and its loading and unloading operations directly impact testing efficiency and product quality. Traditional flip-top sockets typically feature a locking knob and a safety latch. Loading requires unscrewing the knob, lifting the latch to open the socket cover, precisely placing the device into the contacts, closing the socket cover, and tightening the knob with a specific torque. Unloading involves performing the reverse steps to remove the device.

[0003] Currently, this operation relies heavily on manual labor, which presents numerous problems. Firstly, there's the efficiency bottleneck: the cumbersome actions of turning knobs and opening / closing latches are time-consuming and cannot meet the high-throughput demands of modern testing equipment. Secondly, there are quality risks: inconsistent torque during manual knob tightening leads to poor contact; improper operation can easily cause bent device pins and worn socket contacts; frequent hand contact also increases the risk of electrostatic discharge damage. Thirdly, operating costs are high; labor costs are continuously rising, and operational errors result in significant losses of sockets and devices due to scrap. Furthermore, manual operation makes it difficult to accurately record and trace parameters during the loading and unloading process, failing to meet high standards of quality control and data-driven management. Therefore, there is an urgent need to develop automated loading and unloading mechanisms to solve these problems. Utility Model Content

[0019] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0020] Reference Figure 1 , Figure 2 This utility model provides a loading and unloading mechanism for a flip-type socket. This mechanism integrates multiple functional modules such as a capping component 100, a capping component 200, a pick-and-place component 300, and a vision positioning component 400, realizing automated loading and unloading operations for flip-type sockets. This changes the situation of low efficiency, high quality risk, and high cost under the traditional manual operation mode.

[0021] The core of this loading and unloading mechanism lies in breaking down the complex manual operation of the flip-top socket into several controllable automated steps. The capping assembly 100 simulates the action of a human hand opening or closing the socket latch; the cap-screwing assembly 200 replaces the manual tightening or loosening of the socket knob; the pick-and-place assembly 300 handles the gripping, placement, and removal of the device; and the vision positioning assembly 400 acts as the "eyes" throughout the process, providing position and orientation information to each actuator. Together, these components complete the full cycle of opening, loading, closing, and locking the flip-top socket, as well as opening, picking, and closing the socket.

[0022] In the actual workflow, when it is necessary to load the flip-type socket on the aging board, the vision positioning component 400 first locates the knob position, buckle position and cavity center coordinates of the target socket through image acquisition and recognition, and then transmits this position information to the control system.

[0023] Once the flip cover is successfully opened, the pick-and-place assembly 300 begins the device placement operation. Its height-adjustable device gripper 320 grips the device at the location identified by the vision positioning assembly 400, then moves it above the opened socket cavity. After the vision positioning assembly 400 confirms the center position of the cavity, the device is placed inside, ensuring accurate alignment between the device's pins and the socket's contacts. After device placement, the capping assembly 100 activates again, its pressing part 130 applying force to close the flip cover. At this time, the capping switch 220 of the capping assembly 200 re-engages with the knob, applying a specific torque to tighten the knob, firmly locking the socket cover. This ensures a reliable electrical connection between the device's pins and contacts, meeting the requirements of subsequent aging tests.

[0024] The unloading operation is the reverse of the above process. The vision positioning component 400 first identifies the position of the Socket that has been tested. The capping component 200 loosens the knob to unlock it. The pressure cap component 100 opens the latch and lifts the flip cover. The pick-and-place component 300 enters the cavity to pick up the tested device and then moves it to the designated receiving position to release the device. Finally, the pressure cap component 100 and the capping component 200 act in sequence to restore the Socket to its initial closed and locked state, waiting for the next round of loading operation.

[0025] The press-fit part 130 of the cover assembly 100 can be raised and lowered to apply appropriate pressure and stroke, which can ensure that the buckle can be unlocked or locked smoothly, while avoiding damage to the buckle or cover due to excessive force.

[0026] When manually tightening knobs, the torque depends entirely on the operator's feel and experience. This leads to significant differences in torque applied by different operators, and even by the same operator at different times, affecting the contact quality between the socket and the device. The automated capping assembly 200, through the cooperation of the capping switch 220 and the knob, along with the torque control function of the rotary drive system, ensures that the same preset torque value is applied in every tightening operation. This not only improves the reliability of the test but also greatly reduces the risk of socket or device damage due to improper torque.

[0027] The device gripping unit 320 of the pick-and-place component 300 adopts a non-contact or flexible contact gripping method, avoiding the risk of electrostatic discharge that may be caused by direct human contact with the device. This ensures that when the device is placed into the socket cavity, the pins are aligned with the contacts, preventing pin bending or contact damage due to positional deviation. The vision positioning component 400 acquires the position and orientation information of the socket and the device in real time, providing action target points for the other three execution components. This enables the entire loading and unloading process to be intelligent and adaptive. Even if there are slight deviations in the position of different sockets on the aging board, the system can automatically adjust through visual feedback to ensure the accuracy of the operation.

[0028] Reference Figure 4 In practical applications, the pressure cap assembly 100 operates the Socket latch through the cooperation of the first lifting drive component 110 and the pressure rod 120. The first lifting drive component 110 can adopt a structure of closed-loop lead screw motor 312 and linear guide rail 315. The advantage of this structure is that it can provide extremely high position control accuracy and good load-bearing capacity. When the control system sends a lifting command to the closed-loop lead screw motor 312, the lead screw motor 312 drives the lead screw to rotate. Through the linear motion characteristics of the lead screw nut, the pressure rod 120 connected to the lead screw nut moves up and down along the linear guide rail 315. The position of movement is monitored and corrected in real time by the closed-loop feedback system to ensure that the pressure rod 120 can accurately reach the preset target height.

[0029] The sliding member at the end of the pressure rod 120 is a pressure roller structure that can rotate freely relative to the pressure rod 120. When the pressure rod 120 descends and the pressure roller contacts the latch lever surface of the Socket, the pressure roller will not generate frictional resistance with the lever surface, but will move along the lever surface in a rolling manner. This reduces wear on the latch surface and reduces the driving force required for the pressing action, making the operation smoother and more reliable.

[0030] Taking a specific operational process as an example, when the Socket latch needs to be opened, the first lifting drive component 110 drives the pressure rod 120 to move downwards. The pressure roller gradually approaches the latch lever. At the instant the pressure roller just contacts the lever surface, the control system detects the contact signal through the force sensor. At this time, the downward driving force continues to be applied, and the pressure roller rolls along the lever surface and applies pressure. Since the latch lever is usually designed with a certain curvature or angle, the rolling action of the pressure roller will generate a torque that makes the lever rotate. When this torque reaches the critical value required for the latch to unlock, the latch mechanism releases the lock on the flip cover, and the flip cover opens under the action of spring force or its own weight. Throughout the process, the stroke control of the first lifting drive component 110 determines the magnitude and duration of the pressure applied by the pressure roller. By setting these parameters, it can be ensured that the latch can unlock smoothly without causing the lever to deform or break due to excessive pressure.

[0031] The process of closing the Socket latch is similar to the opening process but in the opposite direction. After the Socket cover is closed, the lever 120 descends again to make the pressure roller contact the latch lever. By applying reverse rolling pressure, the lever is rotated to the locking position, and the latch mechanism relocks the flip cover. At this time, the first lifting drive 110 will determine whether the locking is completed according to the preset pressure threshold or position signal. If the locking signal is detected, the lever 120 immediately rises to reset, ready for the next operation.

[0032] Reference Figure 3 The capping assembly 200 includes a second lifting drive 210, a capping drive 221, a rotating rod 222, and a capping cutter 223. This assembly simulates the operation of a human hand tightening a knob, achieving controllable torque and repeatable knob operation. The second lifting drive 210 can also employ a closed-loop screw motor 312 in conjunction with a linear guide rail 315, responsible for moving the entire capping mechanism vertically to the height of the knob, ensuring that the capping cutter 223 can be accurately aligned and inserted into the knob's mating structure.

[0033] The capping drive component 221 typically uses a servo motor 312 as its power source. The output shaft of the servo motor 312 is connected to the rotating rod 222 via a coupling or synchronous belt transmission mechanism. When the servo motor 312 receives a rotation command, its output shaft rotates at a set angle and speed. This rotational motion is transmitted to the rotating rod 222 through the transmission system, thereby driving the capping blade 223 at the end of the rotating rod 222 to rotate synchronously. Because the servo motor 312 has precise angle control and torque feedback functions, it can achieve precise control of the tightening or loosening angle of the knob. At the same time, by monitoring the output torque of the motor 312, it can be determined whether the knob has been tightened or loosened to the correct position.

[0034] As an actuator that directly contacts the knob, the capping knife 223 must match the mating structure on the knob. Taking the slotted knob commonly used in flip-type sockets as an example, the end of the capping knife 223 is machined into a blade shape that matches the slot. When the second lifting drive 210 lowers the capping knife 223 above the knob, the blade part of the capping knife 223 is inserted into the slot. At this time, the capping drive 221 starts to rotate, and the blade applies tangential force in the slot, driving the knob to rotate and completing the tightening or loosening action.

[0035] Specifically, refer to Figure 3 The capping knife 223 has an upwardly extending insertion post. The end of the rotating rod 222 is machined with an insertion cavity for accommodating the insertion post. A compression spring 224 is pre-installed in the insertion cavity. After the insertion post is inserted into the cavity, its bottom abuts against one end of the compression spring 224, and the other end of the compression spring 224 is fixed to the bottom surface of the insertion cavity. The function of this structure is that when the capping knife 223 engages with the knob and begins to rotate, if there is slight jamming or change in resistance, the compression spring 224 can provide axial buffering and compensation, avoiding impact damage to the knob or capping knife 223 caused by rigid transmission. At the same time, the preload of the spring can also ensure that the capping knife 223 and the knob always maintain reliable contact, preventing slippage due to excessive clearance.

[0036] Reference Figure 2 , 5 The pick-and-place assembly 300 uses the cooperation of the third lifting drive 310 and the vacuum nozzle 322 to grasp and release the device. The non-contact vacuum adsorption method avoids stress damage and surface scratches that may be caused by mechanical clamping.

[0037] Reference Figure 6 The third lifting drive component 310 includes a base plate 311 as the mounting base of the entire drive mechanism. A motor 312 is fixedly mounted on one end of the base plate 311 as a power source, and a synchronous pulley 313 is mounted on the other end through a support structure such as a bearing seat. The output shaft of the motor 312 and the synchronous pulley 313 are connected by a ring belt 314. When the motor 312 rotates, its output shaft drives the belt 314 to move, and the movement of the belt 314 drives the synchronous pulley 313 to rotate, forming a continuous transmission circuit.

[0038] A guide rail 315 and a slider 316 are arranged parallel to each other on the base plate 311 along the transmission path of the belt 314. The guide rail 315 is fixed to the surface of the base plate 311, providing guidance for the linear motion of the slider 316. The slider 316 is mounted on the guide rail 315 by means of ball bearings or sliding fit, and can slide along the direction of the guide rail 315, maintaining straightness and positioning accuracy during the sliding process. A belt pressure block 317 is fixed on the slider 316. The belt pressure block 317 is connected to the belt 314 by bolts or clamping mechanism. In this way, when the belt 314 moves under the drive of the motor 312, the belt pressure block 317 acts as a connecting bridge between the belt 314 and the slider 316, converting the linear motion of the belt 314 into the linear motion of the slider 316 along the guide rail 315. The moving distance and speed of the slider 316 are determined by the rotation speed and rotation angle of the motor 312. By controlling the operating parameters of the motor 312, the position and moving speed of the slider 316 can be controlled.

[0039] Reference Figure 5 The suction nozzle connecting rod 321 serves as an intermediate transmission component connecting the slider 316 and the vacuum suction nozzle 322. Its upper end is fixed to the slider 316 via a flange or threaded connection, forming a rigid connection with the slider 316. Its lower end is connected to the vacuum suction nozzle 322. The vacuum suction nozzle 322 can be installed at the lower end of the suction nozzle connecting rod 321 via a quick-change connector or threaded connection, facilitating the replacement of different specifications of suction nozzles according to different device sizes. The base 330 serves as a fixed connection component between the third lifting drive component 310 and the main body of the loading and unloading mechanism. Its upper surface is fixedly connected to the base plate 311 via bolts, forming a stable support frame. The base 330 has through holes or openings through which the vacuum suction nozzle 322 can pass. Driven by the slider 316, it can move up and down relative to the base 330 to grasp and place devices at different heights.

[0040] After the vacuum nozzle 322 picks up the device, the motion platform restarts, moving the pick-and-place component 300 along with the adsorbed device to above the opened socket cavity. The visual positioning component 400 then identifies the position of the cavity center again to ensure that the device can be accurately aligned with the cavity. The third lifting drive component 310 drives the vacuum nozzle 322 to descend again. When the device descends into the cavity and the device pins have been accurately inserted into or aligned with the socket contact position, the control system shuts off the vacuum generator. The negative pressure inside the vacuum nozzle 322 quickly disappears. Under the action of its own weight and the elastic force of the possible elastic contact, the device separates from the nozzle end face and stays stably in the socket cavity, completing the device placement action. Then, the third lifting drive component 310 drives the vacuum nozzle 322 to rise and reset, waiting for the next picking task.

[0041] To further enhance the flexibility and adaptability of the pick-and-place component 300, refer to Figure 5In some application scenarios, the pick-and-place component 300 can also be equipped with a suction nozzle driver 340. This suction nozzle driver 340 typically uses a small servo motor 312 or a stepper motor 312, which is fixedly mounted on the base 330. Its output shaft is connected to the rotating shaft of the vacuum nozzle 322 via gear transmission, belt transmission, or direct coupling. When the vision positioning component 400 identifies that the angle and posture of the device to be loaded are inconsistent with the angle required by the socket cavity, for example, there is a certain angle between the direction of the first pin of the device and the direction of the first contact of the socket, the suction driver can drive the vacuum nozzle 322 to rotate a certain angle after the device is picked up by the vacuum nozzle 322 and before it is placed into the socket cavity, thereby adjusting the angle and posture of the picked-up device, so that the pin arrangement direction of the device is precisely aligned with the contact arrangement direction of the socket, ensuring that the correspondence between the pins and contacts is completely correct after the device is placed in the socket.

[0042] Reference Figure 1 , 2 The vision positioning component 400 employs an AOI (Automated Optical Inspection) mechanism. This mechanism utilizes a high-resolution industrial camera, professional optical lenses, a suitable lighting system, and powerful image processing algorithms to achieve precise identification and positioning of sockets and devices. In practical applications, the vision positioning component 400 is typically installed near or integrated with the pick-and-place component 300. Its field of view covers the area where loading and unloading operations are required, including critical areas such as device storage locations and socket locations.

[0043] Installing the above-mentioned loading and unloading mechanism on the motion platform constitutes a complete flip-type Socket loading and unloading device. The function of the motion platform is to realize the two-dimensional movement of the loading and unloading mechanism in the horizontal plane, so as to perform sequential operation on multiple Sockets distributed in different positions. The motion platform usually adopts an XY gantry structure or an XY stacking platform structure. The X-axis and Y-axis are controlled by independent linear drive systems, such as ball screws with servo motor 312 or linear motor 312 with grating ruler. This structure can provide high speed, high precision and large stroke two-dimensional motion capability.

[0044] In multi-aging board production line applications, the loading and unloading equipment can achieve continuous automated operation by cooperating with the conveying system. The conveying system sequentially feeds the aging boards to be loaded into the working area of ​​the loading and unloading equipment. After the loading and unloading equipment completes the loading of all sockets for an aging board, the aging board is sent by the conveying system to the aging test equipment for testing. At the same time, the next aging board to be loaded is sent in. After a certain period of aging test, the aging board that has completed the test is transported back to the loading and unloading equipment for unloading. The loading and unloading equipment takes out all the tested components and sorts them. Then the empty aging board is removed by the conveying system. The whole process realizes unmanned automatic cycle, which greatly improves production efficiency and equipment utilization, reduces labor costs, and also reduces quality fluctuations caused by human factors, so that the production capacity and quality control level of the aging test link have reached a new level.
