Description

Technical Field

[0001] This utility model relates to the field of gold thread detection technology, specifically to a detection device and an automatic detection equipment. Background Technology

[0002] In traditional gold wire bonding inspection processes, low efficiency and delayed defect identification are particularly prominent issues, severely restricting the production pace of electronic components (such as semiconductor packages). Firstly, the various inspection stages are largely decentralized, requiring manual transfer of materials between barcode scanning and documentation equipment, height measuring instruments, and core inspection devices. Each transfer necessitates repositioning and calibration, consuming significant time in the transfer and debugging phases alone. Furthermore, manual operation is prone to positioning errors due to fatigue, further extending the inspection cycle. Overall efficiency falls far short of matching the production speed of automated production lines.

[0003] More importantly, there is a significant lag in defective product identification. Traditional processes typically involve completing core inspections of the entire batch of materials first, followed by manual verification of the inspection data to screen out defective products. This means that even if a piece of material shows signs of exceeding height limits during the height measurement stage, it still needs to undergo all subsequent inspection steps along with the batch, wasting inspection resources and potentially leading to defective products being mixed with qualified products. By the time defective products are finally identified, some have already entered the subsequent assembly stage, requiring disassembly and rework, further increasing production costs. Furthermore, the delayed identification process prevents timely feedback to the front-end production stages, hindering rapid adjustments to production parameters and potentially leading to more similar defective products, severely impacting production efficiency and product yield.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A detection device is provided, comprising: a barcode scanning mechanism, a detection lateral movement module, a detection lifting module, a height measuring mechanism, a marking mechanism, and a detection mechanism.

[0006] In some embodiments, the detection mechanism includes a detection mounting base and a detection camera, the output end of the detection lifting module is connected to the detection mounting base, and the detection camera is mounted on the detection mounting base.

First, the material is scanned to input information such as model and batch number, establishing a traceability file and avoiding errors and time consumption associated with manual filing. As the material is conveyed, the height measurement mechanism collects the height data of the gold wire in real time, quickly screening out preliminary defective products that exceed tolerances, without waiting for full batch testing. Next, the marking mechanism marks defective products based on defect signals, preventing defective products from being mixed with qualified products. Finally, the core testing mechanism accurately tests the core parameters of compliant materials and verifies the marked defective products as needed. Therefore, it can be seen that the entire process of the device is completely synchronized with the conveying rhythm, enabling simultaneous conveying, testing, and real-time marking. This saves material transfer and waiting time and significantly improves efficiency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] In the following embodiments and accompanying drawings, reference is made to... Figure 1 The coordinate system is defined with the direction of the arrow pointing to the X-axis as right, the direction of the arrow pointing to the Y-axis as front, and the direction of the arrow pointing to the Z-axis as up.

[0021] like Figure 1 As shown, a detection device 10 is provided, including: a barcode scanning mechanism 100, a detection transverse shift module 200, a detection lifting module 300, a height measuring mechanism 400, a marking mechanism 500, and a detection mechanism 600. The output end of the detection transverse shift module 200 is connected to the detection lifting module 300, and the output end of the detection lifting module 300 is connected to the height measuring mechanism 400, the marking mechanism 500, and the detection mechanism 600. The material is conveyed longitudinally, and the barcode scanning mechanism 100, the height measuring mechanism 400, the marking mechanism 500, and the detection mechanism 600 are arranged sequentially along the material conveying direction.

[0022] Specifically, the scanning mechanism 100 is used to read material identification information and can quickly identify barcodes, QR codes, etc. on the material to input information such as material model and batch into the system, providing a basis for subsequent detection data association and traceability. The scanning mechanism 100 includes a scanning mounting base 110 and a scanner 120. The scanning mounting base 110 is located behind the height measuring mechanism 400, and the scanner 120 is mounted on the scanning mounting base 110. The scanner 120 can be, but is not limited to, laser or imaging type. The detection horizontal movement module 200 and the detection lifting module 300 are used to synchronously drive the height measuring mechanism 400, the marking mechanism 500, and the detection mechanism 600 to adjust their positions so that the height measuring mechanism 400, the marking mechanism 500, and the detection mechanism 600 can accurately reach directly above the material to be detected. The detection horizontal movement module 200 drives the three mechanisms to move along the X-axis, and the detection lifting module 300 drives the three mechanisms to move along the Z-axis. The height measuring mechanism 400 is used to measure the height of the material. The marking mechanism 500 is used to mark defective products. The inspection mechanism 600 accurately detects the core parameters of the material, verifies marked defective products as needed, and has storage functions for defective images, defect information, and defective product locations, which can be used for subsequent defect traceability, including production time, product location on the pallet, and defect type. The material conveying direction is set along the Y-axis, that is, the scanning mechanism 100, height measuring mechanism 400, marking mechanism 500, and inspection mechanism 600 are arranged sequentially from back to front. In this embodiment, the material is set as gold thread.

[0023] It's worth noting that by sequentially arranging scanning, height measurement, marking, and testing mechanisms 600 along the material conveying direction, the entire process of material inspection is completed simultaneously during transport: First, the scanning mechanism 100 inputs information such as model and batch number, establishing a traceability file and avoiding errors and time-consuming manual filing; as the material moves forward, the height measurement mechanism 400 collects the height data of the gold thread in real time, quickly screening out preliminary defective products that exceed tolerances, without waiting for full batch inspection; next, the marking mechanism 500 marks defective products based on defect signals, preventing defective products from being mixed with qualified products; finally, the core testing mechanism 600 accurately tests the core parameters of compliant materials and verifies marked defective products as needed. Therefore, it can be seen that the entire process of the device is completely synchronized with the conveying rhythm, enabling simultaneous conveying, inspection, and real-time marking. This saves material transfer and waiting time and significantly improves efficiency; more timely and accurate identification of defective products prevents them from flowing into subsequent stages, reducing resource waste. This ensures production efficiency and product yield.

[0024] To facilitate the installation of the testing agency 600, such as Figure 1 and Figure 2 As shown, in some embodiments, the detection mechanism 600 includes a detection mounting base 610 and a detection camera (not shown in the figure), the output end of the detection lifting module 300 is connected to the detection mounting base 610, and the detection camera is mounted on the detection mounting base 610.

[0025] Specifically, the inspection mounting base 610 is used to position and install the inspection camera. The inspection camera is installed within the inspection mounting base 610. The camera acquires images of the chip's gold wires through a high-resolution optical lens. The system then analyzes and processes the images using advanced image processing algorithms. These algorithms can identify features such as the shape, position, and size of the gold wires and compare them with preset standard images or parameters to detect defects. It can detect problems such as excessively large gold wires, bent gold wires, gold wire adhesion, missing gold wires, misaligned gold balls, tail lines, missing resistors, damaged driver chips, ink spots on the chip, missing capacitors, missing Eeprom chips, chip contamination, missed gold wires, flying wires, gold wire bridging, and collapsed wires. Furthermore, this inspection camera is a 25-megapixel full-color industrial camera capable of performing the above-mentioned inspection items in the prior art.

[0026] In another embodiment, the detection mount 610 is configured as a side-mounted concave shape to embed the detection camera inside the concave shape.

[0027] Specifically, the opening of the concave portion faces rearward, and a detection port is provided at the bottom of the detection mounting base 610. The detection end of the detection camera detects the material through the detection port. The size and shape of the detection port are set as needed to ensure that the material can be detected. The detection camera is installed in the concave portion of the detection mounting base 610, which facilitates the installation and positioning of the detection camera and also protects the detection camera.

[0028] To facilitate the use of the marking mechanism 500, such as Figure 1 and Figure 2 As shown, in some embodiments, the marking mechanism 500 includes a marking lift driver 510 and a marking pen 520. The marking lift driver 510 is connected to the detection mounting base 610, and the output end of the marking lift driver 510 is connected to the marking pen 520.

[0029] Specifically, the marking lift driver 510 is mounted on the left side of the detection mounting base 610. The marking lift driver 510 can be, but is not limited to, a cylinder, to drive the marking pen 520 to approach and mark defective products. The marking pen 520 marks instantly using inkjet or laser. The manner in which the marking lift driver 510 drives the marking pen 520 to rise and fall, and the manner in which the marking pen 520 marks defective products, are known to those skilled in the art and are achievable, and will not be described in detail in this embodiment.

[0030] In another embodiment, the marker lifting driver 510 is directly connected to the output of the detection lifting module 300, and is not connected to the detection mounting base 610.

[0031] To facilitate the installation and use of the lifting drive 510, such as Figure 2 As shown, in some embodiments, the marking mechanism 500 includes a marking mounting plate 530, which is detachably connected to the marking lifting driver 510 and the detection mounting base 610, and the marking mounting plate 530 is used to connect the marking lifting driver 510 to the detection mounting base 610.

[0032] Specifically, the marking mounting plate 530 is connected to the marking lifting driver 510 and the detection mounting base 610 by threads. That is, one side of the marking mounting plate 530 is connected to the detection mounting plate by threads, and the other side is fixed to the marking lifting driver 510 by threads.

[0033] To facilitate the use of the marker pen 520, in some embodiments, the marker mounting plate 530 is provided with a bend to avoid obstructing the detection camera.

[0034] Specifically, the front end of the marking mounting plate 530 is bent to the left, and the lifting driver 510 is connected to the left rear end of the marking mounting plate 530, so that the marking lifting driver 510 and the marking pen 520 are further away from the detection camera, which can greatly avoid the marking mechanism 500 from colliding with the detection camera during operation, thereby extending the service life of the device.

[0035] The specific settings for avoiding bends are subject to actual production conditions and are not specified here.

[0036] like Figure 3 As shown, in another embodiment, the rear end of the marking mounting plate 530 is bent to the right. The lifting driver 510 is connected to the left side of the rear end of the marking mounting plate 530. In this way, while ensuring a certain degree of avoidance effect, the distance between the marking pen 520 and the detection component is closer, which facilitates the detection process.

[0037] To facilitate height measurement, such as Figure 1 and Figure 2 As shown, in some embodiments, the height measuring mechanism 400 is configured as a height measuring instrument, which is mounted on the detection mounting base 610.

[0038] Specifically, the height measuring instrument is positioned at the rear end of the concave portion of the detection mounting base 610 and behind the marking pen 520 to measure the height of the scanned product. The height measuring instrument is used to accurately measure the height, thickness, and other dimensions of objects. Common types include laser and optical instruments, featuring high precision and fast response to ensure product dimensional compliance.

[0039] To facilitate the testing of the transverse movement module, such as Figure 1 and Figure 2 As shown, in some embodiments, the detection lateral movement module 200 includes a detection lateral movement slide rail 210, a detection lateral movement slide plate 220, and a detection lateral movement driver 230. The detection lateral movement slide plate 220 is slidably disposed on the detection lateral movement slide rail 210, the detection lateral movement driver 230 is disposed on the detection lateral movement slide rail 210, the output end of the detection lateral movement driver 230 is connected to the detection lateral movement slide plate 220, and the detection lifting module 300 is connected to the detection lateral movement slide plate 220.

[0040] Specifically, the detection transverse slide rail 210 serves as the basic load-bearing structure, providing stable horizontal guidance for the entire module. The front side of the detection transverse slide plate 220 is slidably mounted on the detection transverse slide rail 210, allowing it to move smoothly along the length direction of the detection transverse slide rail 210, i.e., the X-axis direction. Its rear side is used to connect to the detection lifting module 300. The detection transverse driver 230 can be, but is not limited to, a servo motor or a pneumatic drive device. The detection transverse driver 230 is fixed on the detection transverse slide rail 210, and its power output end is directly connected to the detection transverse slide plate 220, enabling precise control of the movement distance and speed of the detection transverse slide plate 220. By driving the detection transverse slide plate 220 to slide along the detection transverse slide rail 210 through the detection transverse driver 230, the connected detection lifting module 300 and detection components can achieve precise displacement in the X-axis direction, thereby adapting to the detection position requirements of materials of different specifications and ensuring that the detection components can be accurately aligned with the area to be detected. The method by which the detection transverse drive 230 drives the detection transverse slide 220 to slide is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment.

[0041] To facilitate the use of the detection lifting module 300, in some embodiments, the detection lifting module 300 includes a detection lifting slide rail 310, a detection lifting slide plate 320, and a detection lifting driver 330. The detection lifting slide plate 320 is slidably disposed on the detection lifting slide rail 310, the detection lifting driver 330 is disposed on the detection lifting slide rail 310, the output end of the detection lifting driver 330 is connected to the detection lifting slide plate 320, and the height measuring mechanism 400, the marking mechanism 500, and the detection mechanism 600 are connected to the detection lifting slide plate 320.

[0042] Specifically, the detection lifting slide rail 310 serves as the basic load-bearing structure, providing stable horizontal guidance for the entire module. The front side of the detection lifting slide plate 320 is slidably mounted on the detection lifting slide rail 310, allowing it to move smoothly along the length direction of the detection lifting slide rail 310, i.e., the Z-axis direction. Its rear side is used to connect the height measuring mechanism 400, the marking mechanism 500, and the detection mechanism 600. The detection lifting driver 330 can be, but is not limited to, a servo motor or a pneumatic drive device. The detection lifting driver 330 is fixed on the detection lifting slide rail 310, and its power output end is directly connected to the detection lifting slide plate 320, enabling precise control of the movement distance and speed of the detection lifting slide plate 320. By driving the detection lifting slide plate 320 to slide along the detection lifting slide rail 310 through the detection lifting driver 330, the connected detection components can achieve precise displacement in the Z-axis direction, thereby adapting to the detection position requirements of materials of different specifications and ensuring that the detection components can be accurately aligned with the area to be detected. The method by which the detection lifting driver 330 drives the detection lifting slide plate 320 to slide is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment.
