DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-8 , the present invention provides a technical solution: A continuous detection device for integrated circuit packaging includes a base 1, a detection device 2 and a clamping box 3. A vertical guide rail 101 is arranged at the center of the top surface of the base 1, a clamping block adapted to the vertical guide rail 101 is arranged on the bottom surface of the clamping box 3, and rubber pads are arranged at the four corners of the bottom surface of the base 1.

[0022] When using the integrated circuit package continuous detection device 2 , the integrated circuit to be detected is first placed in the clamping box 3 .

[0023] Since a vertical guide rail 101 is provided at the center of the top surface of the base 1 , and a clamping block adapted thereto is provided on the bottom surface of the clamping box 3 , the clamping box 3 can smoothly move up and down along the vertical guide rail 101 by virtue of the cooperation between the clamping block and the vertical guide rail 101 .

[0024] This movement process provides a flexible position adjustment function for the subsequent detection process, so that the integrated circuit can accurately dock with the detection components of different heights of the detection device 2.

[0025] During detection, the detection device 2 starts the corresponding detection program, whether it is the visual scanning of the appearance detection or the signal input and monitoring of the electrical performance test, it can operate on the integrated circuit fixed by the clamping box 3.

[0026] The rubber pads arranged at the four corners of the bottom surface of the base 1 play a role in stabilizing the entire device to prevent the detection accuracy from being affected by slight vibrations during the detection process.

[0027] The combination of the vertical guide rail 101 and the card block allows the clamping box 3 to carry the integrated circuit to achieve precise vertical displacement, ensuring that the integrated circuit can be accurately in the optimal position required by the detection device 2 during detection, which helps to improve detection accuracy and reduce misjudgment caused by position deviation. Whether it is checking the appearance of subtle parts such as pins or testing electrical connection points, it can be carried out more accurately.

[0028] The rubber pad at the bottom of the base 1 can effectively buffer external vibration interference.

[0029] Integrated circuit testing often requires high-precision measurements. Even extremely small vibrations may cause poor contact between the detection probe and the pin, or cause the visual inspection image to appear blurred or jittery. The presence of rubber pads maintains a relatively stable testing environment, ensuring the accuracy and reliability of test data.

[0030] With such a simple structural design, the device is relatively compact as a whole and does not occupy too much space, making it suitable for layout in the limited space of an integrated circuit production workshop.

[0031] At the same time, the detachable cooperation between the clamping box 3 and the vertical guide rail 101 also provides convenience for subsequent maintenance and replacement of parts, reducing the cost and difficulty of equipment operation and maintenance.

[0032] As a component that carries the integrated circuit, the clamping box 3 has a simple structure that is easy to modify and can adapt to integrated circuits of different sizes and packaging types, thereby enhancing the compatibility of the entire detection device 2 with diversified products, broadening the application scope of the device, and meeting the detection tasks of different production batches and different customer needs.

[0033] The detection device 2 is arranged on the front side of the base 1, and the detection device 2 includes two columns. A probe 201 is arranged at the inner lower end of the column, and the camera end of the probe 201 is inclined upward. Guide blocks are arranged between the columns, and a detection plate 204 is slidably connected between the guide blocks. A motor 202 is arranged on the outer side of one of the columns, and the output shaft of the motor 202 is fixedly connected to a screw 203 threadedly connected to the detection plate 204.

[0034] When the detection device 2 starts to operate, the motor 202 is started first. The output shaft of the motor 202 drives the screw 203 to rotate. Since the detection plate 204 and the screw 203 are in a threaded connection relationship, and the detection plate 204 is restricted between the guide blocks between the two columns, it can only slide linearly along the guide blocks and cannot rotate with the screw 203.

[0035] Therefore, as the screw rod 203 rotates, the detection plate 204 will move up and down smoothly along the axial direction of the screw rod 203 under the constraint of the guide block.

[0036] The probe 201 located at the lower inner end of the column has its camera end tilted upward. When the detection plate 204 moves up and down, the probe 201 can capture images of integrated circuits at different heights from an inclined angle.

[0037] When the integrated circuit is placed in a suitable position, the probe 201 continuously collects image data. With the dynamic displacement of the detection board 204, it realizes all-round and multi-height visual monitoring of the integrated circuit's appearance, without missing any possible appearance defects, such as pin deformation, package shell scratches, unclear markings, etc.

[0038] The camera end of the probe 201 is tilted upward, and the up and down movement of the detection plate 204 greatly expands the coverage of the visual detection.

[0039] Compared with cameras with fixed angles and a single height, this design can capture the appearance details of integrated circuits at all heights and angles, significantly reducing blind spots in visual inspection and improving the comprehensiveness of inspection, thereby more accurately detecting subtle defects and ensuring product appearance quality.

[0040] The moving accuracy of the detection plate 204 is ensured by the transmission system composed of the motor 202, the screw rod 203 and the guide block.

[0041] The threaded transmission of the screw 203 can achieve relatively precise displacement control, and the guide block provides stable support and guidance for the detection plate 204 to prevent it from shaking and offset during movement, so that the image collected by the probe 201 always remains clear and stable, providing a high-quality data basis for subsequent image analysis.

[0042] The overall detection device 2 only relies on two columns, a simple guide block, a screw 203 and a motor 202 to build an efficient detection architecture. The structure is very compact and does not take up too much space. It is conducive to layout in the limited space of an integrated circuit production workshop and reduces the space cost of the equipment.

[0043] Moreover, this simple mechanical structure has a relatively low failure rate and is more convenient and quick to maintain, which helps reduce equipment downtime and improve production efficiency.

[0044] This detection structure is easy to adjust and optimize, such as replacing the probe 201 with different focal lengths and resolutions, or adjusting the pitch of the screw 203 to change the moving speed of the detection plate 204. It can quickly adapt to integrated circuit products of different specifications and different detection accuracy requirements, showing good flexibility and product adaptability.

[0045] A connecting rod 301 is rotatably connected in the clamping box 3, and the connecting rod 301 is connected to multiple sections of bidirectional screws 203. Two guide plates 302 are mirror-imaged on each section of the bidirectional screw 203. A driving column 304 is connected to one end of the connecting rod 301, and a torsion spring 305 is arranged between the driving column 304 and the clamping box 3.

[0046] In the integrated circuit packaging continuous detection device 2, the clamping box 3 is an important component for achieving stable clamping of the integrated circuit.

[0047] In the initial state, due to the existence of the torsion spring 305, it will prevent the driving column 304 from rotating. At this time, the connecting rod 301 remains stable, and the two guide plates 302 on the multi-section bidirectional screw 203 fit each other.

[0048] When the integrated circuit needs to be clamped, the operator manually rotates the driving column 304 . During this process, the torsion spring 305 is deformed by force, and the rotation of the driving column 304 is transmitted to the multi-section bidirectional screw 203 through the connecting rod 301 .

[0049] Since the bidirectional screw 203 has bidirectional threads, when it rotates, the two guide plates 302 mirror-imaged thereon will simultaneously move in opposite directions along the threads of the bidirectional screw 203, thereby increasing the distance between them.

[0050] Then, the driving column 304 is released, and under the elastic force of the torsion spring 305, the driving column 304 will reset, driving the connecting rod 301 and the bidirectional screw 203 to reverse, and the two guide plates 302 will move toward each other, automatically adjusting the spacing according to the size of the integrated circuit, and adaptively clamping the integrated circuit.

[0051] The principle of this adaptation is based on the elastic force of the torsion spring 305 and the thread transmission characteristics of the bidirectional screw 203. Through the synergistic effect of the two, integrated circuits of different sizes can be tightly and firmly clamped to ensure that the integrated circuits will not be displaced or shaken during the detection process, thereby ensuring the stability and reliability of the detection process.

[0052] Through the ingenious combination of the bidirectional screw 203 and the torsion spring 305, adaptive clamping of integrated circuits of different sizes can be achieved without frequent manual adjustment or replacement of the clamp, which significantly improves the versatility and operational convenience of the device.

[0053] Regardless of the size of the integrated circuit, the clamping box 3 can automatically adjust the spacing of the guide plates 302 according to its actual size to ensure firm clamping, thereby greatly improving work efficiency.

[0054] The operator only needs to rotate the drive column 304 and release it to complete the clamping operation of the integrated circuit. The operation steps are simple and easy to master, which reduces the operation difficulty and labor intensity of the operator and also reduces the risk of damage to the integrated circuit due to improper operation.

[0055] After the guide plate 302 clamps the integrated circuit, the return force of the torsion spring 305 continues to act, which can provide a stable clamping force for the integrated circuit, ensuring that the integrated circuit is fixed in position during the detection process, avoiding the impact of vibration, movement and other factors during the detection process on the detection results, providing a stable and reliable operating environment for subsequent detection work, and ensuring detection accuracy.

[0056] The entire clamping structure is designed inside the clamping box 3, and the overall structure is compact and does not occupy too much extra space.

[0057] At the same time, the elastic restoring force of the torsion spring 305 and the mechanical transmission principle of the bidirectional screw 203 are utilized to ensure the reliability of the structure, reduce the complex mechanical structure and power source, and reduce the maintenance cost of the device and the possibility of failure.

[0058] Furthermore, it also includes an adjusting column 4, on which a driving roller 402 is arranged, a connecting groove 303 is opened at the top of the clamping box 3, the top of the guide plate 302 passes through the connecting groove 303 and is rotatably connected to an adjusting plate 306, a sliding groove is opened in the adjusting plate 306, and the telescopic column 403 can only be slidably arranged in the sliding groove along the opening direction of the sliding groove, a docking spring 405 is arranged between the telescopic column 403 and the sliding groove, and a driven roller 404 engaged with the driving roller 402 is arranged on the telescopic column 403.

[0059] The driving roller 402 and the driven roller 404 are both truncated cone-shaped, and are each provided with a plurality of rectangular protrusions distributed along their side walls. The rectangular protrusions on the driving roller 402 and the driven roller 404 engage with each other, and the driven roller 404 can slide on the protrusions of the driving roller 402 along its side wall.

[0060] When faced with integrated circuits with three-dimensional pins at different angles, which need to be adapted, clamped and precisely positioned, the adjustment column 4 begins to play a key role.

[0061] The driving roller 402 on the adjusting column 4 starts to rotate under the drive of external power (such as manual rotation).

[0062] Since the driving roller 402 and the driven roller 404 are both in a truncated cone shape, and the rectangular protrusions on the side walls of the two are engaged with each other, when the driving roller 402 rotates, the driven roller 404 is driven to rotate synchronously by the meshing force between the protrusions.

[0063] One end of the telescopic column 403 is connected to the driven roller 404, and the other end is embedded in the slide groove of the adjustment plate 306, and can only slide along the slide groove direction. The docking spring 405 provides elastic support to allow the telescopic column 403 to always fit closely with the driving roller 402.

[0064] As the driven roller 404 rotates, the adjustment plate 306 rotates with the connection point between the adjustment plate 306 and the guide plate 302 as the axis due to the force, thereby causing the guide plate 302 to change in angle or position.

[0065] Because of the truncated cone-shaped driving roller 402 and driven roller 404, during the rotation process, the driven roller 404 can "climb" or "descend" along the side wall of the driving roller 402, that is, slide along the protrusion. This feature allows the guide plate 302 to not only translate within the plane, but also achieve multi-dimensional angle adjustment.

[0066] The operator can flexibly adjust the rotation direction and amplitude of the driving roller 402 according to the specific angle and position of the three-dimensional pins, so as to enable the guide plate 302 to accurately adapt to the integrated circuit and firmly clamp it, thus providing a stable basis for subsequent inspection.

[0067] In view of the complex layout of three-dimensional pins at different angles and spatial positions, the structure can dynamically adjust the guide plate 302 to achieve all-round and multi-angle fitting and clamping.

[0068] Regardless of whether the pins are tilted upward, tilted sideways, or distributed in multiple layers, they can be accurately positioned, solving the problem that traditional fixtures are difficult to handle with three-dimensional pins, and significantly improving the device's compatibility with complex integrated circuit packaging.

[0069] The special shapes and protrusion engagement design of the driving roller 402 and the driven roller 404, together with the telescopic column 403 and the adjustment plate 306, endow the adjustment system with extremely high precision.

[0070] The operator can achieve subtle and precise position and angle changes of the guide plate 302 with a relatively small adjustment range, thereby minimizing detection errors caused by clamping deviations and ensuring the accuracy of detection data.

[0071] The docking spring 405 absorbs excess energy during adjustment and prevents rigid collision between components.

[0072] When unexpected resistance is encountered during adjustment, the spring buffer can prevent damage to key components such as the driving roller 402 and the driven roller 404, maintain the stability of the device, reduce the number of maintenance times, ensure long-term stable operation, and improve the overall detection efficiency.

[0073] The operator only needs to control the rotation of the driving roller 402 to indirectly and flexibly control the posture of the guide plate 302, and the operation is intuitive and simple.

[0074] Compared with complex multi-axis robotic arms or multi-component linkage fixtures, this design lowers the operating threshold, shortens adjustment time, and is easier to integrate into efficient production processes.

[0075] A plurality of rotating frames 401 are spaced apart on the clamping box 3 , the adjusting column 4 is connected to the rotating frame 401 with damping rotation, and the driving roller 402 is mirror-imaged at both ends of the rotating frame 401 and the base 1 or between two adjacent rotating frames 401 .

[0076] A plurality of rotating frames 401 are evenly spaced and distributed on the clamping box 3 , providing a stable installation position for the adjusting column 4 .

[0077] The adjusting column 4 is rotatably connected to the rotating frame 401 in a damped manner, which means that the adjusting column 4 will be hindered by a certain friction force when rotating and cannot rotate freely and arbitrarily.

[0078] When the operator manually applies force to overcome the damping, the adjustment column 4 will slowly rotate. This design makes the adjustment process more controllable.

[0079] The driving rollers 402 are arranged in a mirror image at specific positions, whether at the two ends of the rotating frame 401 and the base 1 or between two adjacent rotating frames 401 , which cleverly utilizes the spatial structure of the device.

[0080] When the adjusting column 4 rotates, the driving roller 402 rotates synchronously therewith, and transmits the rotational motion to the driven roller 404 by means of the rectangular protrusions that engage with each other.

[0081] The driven roller 404 then drives the adjustment plate 306 through the telescopic column 403, and finally prompts the guide plate 302 to make an angle or position adjustment, thereby optimizing the clamping of the integrated circuit.

[0082] Due to the layout characteristics of the driving roller 402, an adjustment force can be applied to the guide plate 302 from multiple dimensions to meet the complex and diverse integrated circuit shape adaptation requirements.

[0083] The damped rotation connection gives the adjustment column 4 a high-precision adjustment capability. The operator can fine-tune the angle of the adjustment column 4 in a small range and accurately change the position of the guide plate 302, so that the clamping box 3 can fit tightly to integrated circuits of different sizes and shapes, greatly reducing the detection error caused by unstable clamping and significantly improving the detection accuracy. It is especially suitable for the detection of high-end integrated circuits with dense pins and precise packaging.

[0084] The existence of damping enables the adjustment column 4 to resist interference factors such as slight vibrations and collisions during daily operation, and will not easily move or rotate, thereby ensuring that the guide plate 302 always maintains an ideal clamping posture.

[0085] In a noisy production workshop environment with vibration sources, it can still provide stable support for integrated circuits, ensuring the continuity of the detection process and accurate results.

[0086] The mirror-image arrangement of the driving roller 402 makes full use of the "idle" space between the rotating frame 401 and the base 1 and between the rotating frames 401, so that the adjusting components can complete complex adjustment functions without occupying too much extra space, making the entire device structure more compact, which helps to reasonably layout the limited workshop workstations and save valuable production space.

[0087] Moderate damping avoids excessive and rapid ineffective rotation of the adjustment column 4, reduces unnecessary wear between components, and extends the service life of components such as the rotating frame 401 and the driving roller 402 connected thereto because of more uniform force and smoother rotation.

[0088] This means that the frequency of equipment maintenance and parts replacement is reduced, which in the long run significantly reduces the maintenance costs and downtime of the equipment.

[0089] An extension piece is provided at one end of the adjusting column 4 located on the front side of the clamping box 3, and a rotating handle is provided on the extension piece.

[0090] In this integrated circuit package continuous detection device 2, an end of the adjustment column 4 located at the front side of the clamping box 3 is equipped with an extension piece, and a rotating handle is installed on the extension piece.

[0091] When the guide plate 302 holding the integrated circuit needs to be adjusted, the operator applies external force by holding the rotating handle.

[0092] Since the rotating handle is connected to the extension piece, and the extension piece is fixed together with the adjusting column 4, the operator can easily drive the adjusting column 4 to overcome the damping between it and the rotating frame 401 and rotate around the rotating axis by manually rotating the rotating handle.

[0093] Once the adjustment column 4 starts to rotate, it will drive the driving roller 402 connected to it to rotate synchronously. Subsequently, with the help of the engagement transmission between the driving roller 402 and the driven roller 404, the adjustment plate 306 drives the guide plate 302 to complete the position or angle adjustment, and finally achieves a more accurate and fitting clamping effect for integrated circuits of different specifications.

[0094] The setting of the rotating handle greatly improves the operating feel and convenience.

[0095] Twisting the adjustment column 4 directly by hand is not only laborious, but also difficult to accurately control the rotation angle. The turning handle is equivalent to extending the force arm. The operator only needs to gently hold and turn it to drive the adjustment column 4 with less force, making the adjustment action easier and smoother, reducing the operator's labor intensity, and not easily fatigued even if the operation is carried out frequently for a long time.

[0096] The extension piece cooperates with the rotating handle to allow the operator to control the rotation of the adjustment column 4 more accurately.

[0097] Small and delicate rotation movements can more accurately control the rotation amount of the driving roller 402, and then precisely adjust the displacement and angle change of the guide plate 302 to meet the subtle shape and size differences of various integrated circuits, reduce over-clamping or inadequate clamping caused by excessive adjustment, and effectively improve detection accuracy.

[0098] The rotating handle is located on the front of the clamping box 3 and is within the direct field of vision of the operator.

[0099] During the adjustment process, the operator can intuitively observe the rotation of the handle and simultaneously estimate the adjustment status of the guide plate 302, so as to facilitate real-time fine-tuning of the operation according to the actual clamping requirements of the integrated circuit, realize visual and real-time precise adjustment, avoid time waste caused by repeated adjustments, and improve detection efficiency.

[0100] Integrated circuits of different batches and models vary greatly in package size and pin layout. By easily adjusting the guide plate 302 by turning the handle, the clamping box 3 can quickly adapt to these differences without the need for a complicated fixture replacement process, thereby enhancing the adaptability of the entire detection device 2 to diversified integrated circuit products and broadening the application scope of the device.
