[0073] Ceramic packaging shells have the advantages of good airtightness, small thermal expansion coefficient, high mechanical strength, good moisture resistance, and high thermal conductivity, and are widely used in the fields of electronic equipment such as aerospace, aviation, shipborne, missileborne, and early warning detection, and play an indispensable supporting role in the application of high-reliability components.

[0074] Ceramic quad flat package (CQFP) has the characteristics of small volume, light weight, high packaging density, and good thermal-electric performance, and is suitable for surface mounting. At present, in the inspection of CQFP ceramic shells, due to the many shell inspection items, for multi-outlet products, the bottom pads and bonding fingers are dense, such as Figure 1As shown, the general electronic product inspection equipment cannot fully inspect the CQFP type ceramic shell, therefore, at present, it still almost completely relies on manual work, and the following disadvantages exist in simply relying on manual work: (1) low efficiency: each lead-out end of the shell needs to be carefully observed by the inspector to see if there are problems such as multiple gold, missing gold and virtual welding; meanwhile, the text does not match conditions such as reverse marking angle and reverse lead wire welding occur from time to time, so the front and back of each product must be combined to see, and the inspection speed is slow, and after adjustment and innovation in recent years, the workload of a single person in manual inspection has reached a bottleneck; (2) easy to miss: product defects are complex and changeable, manual inspection is easily affected by factors such as energy and emotion, and problems such as multiple gold, solder wire and virtual welding are easy to miss, which affects product quality.

[0075] In view of the problems of low efficiency and easy to miss, the application designs an automatic inspection equipment for CQFP type ceramic shell, from the tray form of the feeding and discharging mechanism, the industrial computer is connected to the mechanical arm carrying mechanism, and the combination of the rotary table type station conversion mechanism and the visual positioning and inspection module is used to detect various product defects of the CQFP type ceramic shell.

[0076] Based on the above problems, the application will be further described in detail in combination with the drawings and specific embodiments.

[0077] Figure 2 Fig. 1 is a structural schematic diagram of an automatic inspection equipment for CQFP type ceramic shell, Figure 3 Fig. 2 is a specific structural schematic diagram of an automatic inspection equipment for CQFP type ceramic shell, referring to Figure 2 and Figure 3 An automatic inspection equipment for CQFP type ceramic shell, comprising: a feeding and discharging mechanism 100, a mechanical arm carrying mechanism 200, a rotary table type station conversion mechanism 300, a visual positioning and inspection module 400 and an industrial computer 500.

[0078] The feeding and discharging mechanism 100 comprises a feeding mechanism 101, a discharging mechanism 102 and a plurality of child-mother type trays; the plurality of child-mother type trays are respectively placed on the feeding mechanism 101 and the discharging mechanism 102, and the child-mother type tray is used for containing a preset number of CQFP type ceramic shells.

[0079] The mechanical arm carrying mechanism 200 is used for carrying the CQFP type ceramic shell from the child-mother type tray on the feeding mechanism 101 to the boss detection tooling 301 on the rotary table type station conversion mechanism 300, and carrying the CQFP type ceramic shell from the boss detection tooling 301 to the child-mother type tray on the discharging mechanism 102.

[0080] The rotating disc type station conversion mechanism 300 is used to rotate the boss detection tool 301 placed with the CQFP type ceramic shell to the corresponding position of each detection module of the visual positioning and inspection module 400; the rotating disc type station conversion mechanism 300 comprises a plurality of boss detection tools 301.

[0081] The visual positioning and inspection module 400 is used to perform photographic detection on the CQFP type ceramic shell by each detection module, and send the photographic detection information to the industrial computer 500. The photographic detection information can be photographic information.

[0082] The industrial computer 500 is used to process the photographic detection information to obtain the final detection result of the CQFP type ceramic shell.

[0083] The feeding and discharging mechanism 100, the mechanical arm carrying mechanism 200, the rotating disc type station conversion mechanism 300 and the visual positioning and inspection module 400 are connected with the industrial computer 500 through wired or wireless mode for data transmission and corresponding control.

[0084] For example, according to the positioning effect of the visual positioning and inspection module 400, the mechanical arm carrying mechanism 200 automatically carries the product CQFP type ceramic shell to be detected, and then according to the comprehensive detection of the product CQFP type ceramic shell by the plurality of detection modules of the visual positioning and inspection module 400, all defects can be covered, and the mechanical arm carrying mechanism 200 automatically classifies and places the detected CQFP type ceramic shell into the sub-mother type tray, so that automatic inspection can be realized, the product detection efficiency is improved, and the inspection quality is ensured while all defects are covered.

[0085] In an embodiment, the sub-mother type tray comprises a mother tray and a sub-tray, and the sub-tray is placed in the mother tray; the sub-mother type tray is used to place the CQFP type ceramic shell to be detected, the qualified CQFP type ceramic shell and the unqualified CQFP type ceramic shell. As shown in the figure, the feeding and discharging mechanism 100 can be provided in the form of four-station sub-mother type tray + drawer type, and the four-station tray is an upper feeding tray, an empty tray, a qualified product discharging tray and an unqualified product discharging tray. Figure 4

[0086] For example, the feeding mechanism and the discharging mechanism can be provided in a split manner. A plurality of upper feeding trays containing the CQFP type ceramic shell to be detected are placed at a of the feeding mechanism 101, and a plurality of empty trays are placed at b of the feeding mechanism 101, and generally 3 empty trays are placed at b when the equipment is started. The sub-mother type trays at c and d of the discharging mechanism 102 are carried by the mechanical arm from b, and are used to contain the qualified CQFP type ceramic shell and the unqualified CQFP type ceramic shell respectively.

[0087] ​Exemplarily, the loading tray is moved to the lower side of the clamping structure, the clamping structure clamps one loading tray, moves to the fixed position on the upper side, the mechanical arm grabs the CQFP ceramic shell to be detected from the loading tray located at the fixed position, and when the CQFP ceramic shell in the loading tray is grabbed, the mechanical arm grabs the tray to b as an empty tray for standby.

[0088] It is also not excluded that the plurality of loading trays a and the plurality of empty trays b in the plurality of primary and secondary trays are placed on the loading mechanism, and the plurality of qualified unloading trays c and the plurality of unqualified unloading trays d are directly placed on the unloading mechanism.

[0089] The tray adopts a primary and secondary tray form, as shown in Figure 5 The primary tray adopts a blister material, which is used to place the CQFP ceramic shell and ensure that the gold plating layer of the product is not scratched, and the cost is low. The secondary tray can adopt an aluminum alloy material, which is used to carry the primary tray, and when the air cylinder clamp moves the loading and unloading tray, the hardness is high and is not easy to deform. And through the combination form of the primary and secondary trays, a plurality of different models of CQFP ceramic shells can be set, which are directly placed in the secondary tray, improving the compatibility of the equipment. The data of the primary and secondary trays are shown in Table 1.

[0090] Table 1 Design of Primary and Secondary Trays

[0091]

[0092] Exemplarily, a plurality of groups of CQFP ceramic shells to be detected are placed in the loading tray, and the mechanical arm carrying mechanism 200 grabs the CQFP ceramic shells to be detected according to the preset order. When the CQFP ceramic shells in one tray are grabbed, the air cylinder clamp moves the tray to the position of the empty tray. A predetermined number of empty trays are placed in advance before detection, which are used to prepare for the unloading tray. The unloading tray can include a qualified unloading tray and an unqualified unloading tray of the CQFP ceramic shell. After the unloading tray is full, it is taken away.

[0093] In an embodiment, the mechanical arm carrying structure 200 adopts a high-speed and high-precision mechanical arm. The mechanical arm can receive the positioning or detection information sent by the industrial computer 500, and based on the positioning or detection information, the CQFP ceramic shell is carried to the specified position. The coverage range of the mechanical arm of the mechanical arm carrying structure is shown by the dashed line e in Figure 2 . The mechanical arm of the mechanical arm carrying structure has a long coverage range and high efficiency. The mechanical arm can be attached with two suction cups, the size of which is adapted to the size of the CQFP ceramic shell to be detected, and the corresponding suction cup can be replaced according to different models of products. And during the detection process, the same size suction cup is used, which can also be used for product caching, further improving the efficiency of product loading and unloading.

[0094] In one embodiment, the rotary station conversion mechanism 300 includes an inner disk 302 and an outer disk 303, with the outer disk 303 rotating around the inner disk 302; a vision positioning and inspection module 400 is installed on the inner disk 302 and around the outer disk 303; the outer disk 303 is provided with a plurality of boss detection fixtures 301, which are used to place CQFP-type ceramic shells.

[0095] For example, a rotary workstation conversion mechanism 300 Figure 6 As shown, it is divided into an inner disc 302 and an outer turntable 303. The inner disc 302 does not rotate and only provides partial vision positioning and the installation position of the inspection module 400. The outer turntable is driven by a servo DD motor, which has high precision and angle compensation function.

[0096] The exemplary outer turntable 303 can be equipped with 12 boss detection fixtures 301. When the turntable rotates, it can simultaneously detect 12 CQFP-type ceramic shells, greatly improving detection efficiency. In practice, this turntable structure is small in size, and as many boss detection fixtures 301 as possible can be arranged according to the actual dimensions.

[0097] In one embodiment, the layout of the visual positioning and inspection module 400 is as follows: Figure 7 As shown, the overall design adopts a turntable, with the workstations of each inspection module distributed around the turntable. The vision positioning and inspection module 400 includes a loading positioning module 401, a first bottom surface inspection module 402, an outer ceramic body inspection module 403, a first front inspection module 404, a second front inspection module 405, an inner ceramic body inspection module 406, a unloading positioning module 407, and a second bottom surface inspection module 408.

[0098] The loading and positioning module 401 is installed above the loading mechanism 101 and is used to capture and position the CQFP type ceramic shell in the loading mechanism 101, obtain the first capture and positioning information, and send the first capture and positioning information to the industrial control computer 500.

[0099] For example, in the process of inspecting the CQFP ceramic housing, the CQFP ceramic housing needs to be picked out one by one from the feeding tray, so the feeding positioning module 401 uses the visual positioning device to take a picture and position, obtains the shooting positioning information of the CQFP ceramic housing in the feeding tray, and then sends a signal to the industrial computer 500, which processes the shooting positioning information and sends it to the mechanical arm for accurate picking, so as to perform the first bottom surface detection. At the same time, the feeding positioning module 401 can also identify the model of the CQFP ceramic housing through machine vision, so as to set the initial data of the entire detection process for the industrial computer 500, including the number of CQFP ceramic housings in each feeding tray, the detection item setting of the visual positioning and inspection module 400, the height and angle setting of the camera in each module of the visual positioning and inspection module 400, etc.

[0100] For example, the initial data of the entire detection process described above can also be set manually for the industrial computer 500 before detection.

[0101] In an embodiment, the first bottom surface detection module 402 is arranged between the feeding mechanism 101 and the rotary table type station conversion mechanism 300, and is used to detect the pads and solder of the bottom surface of the CQFP ceramic housing during the process that the mechanical arm handling mechanism 200 carries the CQFP ceramic housing from the sub-mother tray on the feeding mechanism 101 to the convex post detection tooling 301, obtains the first shooting detection information, and sends the first shooting detection information to the industrial computer 500.

[0102] For example, the first bottom surface detection module 402 detects the bottom surface of the CQFP ceramic housing when the mechanical arm handling mechanism 200 picks up the CQFP ceramic housing in the air, without the need to flip the CQFP ceramic housing on the tooling or other operations, which is simple and easy to operate and improves the detection efficiency. Therefore, the specific position of the first bottom surface detection module 402 is not limited to the position shown in Figure 2 and Figure 7 The actual position should be able to shoot the bottom surface of the CQFP ceramic housing.

[0103] In an embodiment, the outer ceramic body detection module 403 is used to detect the outer ceramic body of the CQFP ceramic housing placed on the convex post detection tooling 301, obtain the second shooting detection information, and send the second shooting detection information to the industrial computer 500.

[0104] For example, the outer ceramic body detection module 403 is arranged between the convex post detection tooling 301 and the rotary table type station conversion mechanism 300. Figure 7The middle dotted line 403 area position is used to realize complete shooting of the four sides of the CQFP ceramic shell. Each type of CQFP ceramic shell is provided with a preset shooting angle. Four cameras including a first camera 4031, a second camera 4032, a third camera 4033 and a fourth camera 4034 can be provided. As shown in FIG. 4, the four cameras are automatically rotated to the preset shooting angle. The cameras can upload the shooting detection information to the industrial computer 500. Figure 8

[0105] In an embodiment, the first front detection module 404 is used to perform shooting detection on the bonding fingers and the core area of the front of the CQFP ceramic shell placed on the boss detection tool 301 to obtain third shooting detection information, and send the third shooting detection information to the industrial computer 500. The front of the CQFP ceramic shell is opposite to the bottom surface.

[0106] The second front detection module 405 is used to perform shooting detection on the sealing ring and the lead of the front of the CQFP ceramic shell placed on the boss detection tool 301 to obtain fourth shooting detection information, and send the fourth shooting detection information to the industrial computer 500.

[0107] For example, the first front detection module 404 is arranged above the outer turntable to perform shooting detection on the bonding fingers and the core area of the front of the CQFP ceramic shell. The second front detection module 405 is arranged above the outer turntable to perform shooting detection on the sealing ring and the lead of the front of the CQFP ceramic shell. Since the detection field of view of the bonding fingers and the core area is small, and the detection field of view of the sealing ring and the lead is large, two detection modules are used to perform detection, different detection field of views are set, and the accuracy of the final detection result can be improved.

[0108] In an embodiment, the inner ceramic body detection module 406 is used to perform shooting detection on the inner ceramic body of the CQFP ceramic shell placed on the boss detection tool 301 to obtain fifth shooting detection information, and send the fifth shooting detection information to the industrial computer 500.

[0109] For example, since most of the CQFP ceramic shells have a three-dimensional shell structure, and the wall structure around the four sides is low, different shooting angles are set to shoot the inside of the CQFP ceramic shell, so that the detection of the inner ceramic body is realized. Similarly, each type of CQFP ceramic shell is provided with a preset shooting angle. Four cameras can be provided. The four cameras are automatically rotated to the preset shooting angle. Four camera schemes are used to detect the ceramic body outer wall. Only one shooting is needed to realize the detection of the four outer sides. The detection of multiple gold, ceramic collapse and dirt can be realized, so that the detection efficiency and inspection effect are greatly improved. The cameras can upload the shooting detection information to the industrial computer 500. ​

[0110] In an embodiment, the blanking positioning module 407 is configured to perform photographic positioning on the CQFP ceramic housing on the boss detection tool 301, obtain second photographic positioning information, and send the second photographic positioning information to the industrial computer 500.

[0111] For example, after the first bottom surface detection, the outer ceramic body detection, the first front surface detection, the second front surface detection, and the inner ceramic body detection are all completed, the turntable rotates the CQFP ceramic housing under detection to the position of the blanking positioning module 407. When the blanking positioning module 407 detects that there is a product, it performs photographic positioning. Then, the industrial computer 500 notifies the mechanical arm handling mechanism 200 to clamp the CQFP ceramic housing at this position.

[0112] In an embodiment, the second bottom surface detection module 408 is arranged between the blanking mechanism 102 and the turntable type station conversion mechanism 300. During the process of the mechanical arm handling mechanism 200 classifying and handling the CQFP ceramic housing to the sub-mother type tray on the blanking mechanism 102, the second bottom surface detection module 408 is configured to perform photographic detection on the leads and ceramic body of the bottom surface of the CQFP ceramic housing, obtain sixth photographic detection information, and send the sixth photographic detection information to the industrial computer 500.

[0113] For example, when the mechanical arm handling mechanism 200 grabs the CQFP ceramic housing in the air, the second bottom surface detection module 408 performs photographic detection on the bottom surface of the CQFP ceramic housing. Without the need for flipping the CQFP ceramic housing on the tool or other operations, it is simple and easy to use, and improves the detection efficiency. Therefore, the specific position of the second bottom surface detection module 408 is not limited to the position shown in Figure 2 and Figure 7 The actual position should be able to photograph the bottom surface of the CQFP ceramic housing.

[0114] For example, the visual positioning and inspection module 400 must ensure the clarity of the photographs of each part to form stable and clear photos that can be uploaded to the industrial computer 500 for algorithm analysis. It can be said that the clarity of the photographs is the basis of detection. Because the ceramic housing has a complex shape and many dead angles, the photographic angle is required to be very high. At the same time, because the defect types of different parts are different, different light source types are needed to clearly image, so different light source types are needed for photographing at the same position.

[0115] For example, before the industrial computer 500 performs algorithm analysis, the inspection software in the industrial computer 500 performs a large amount of AI training and establishes a database in a manner, which realizes 100% detection of all defects of the ceramic housing.

[0116] In the visual positioning and inspection module 400, AI learning is used to analyze different detection areas and the presence characteristics of defects, and a multi-station + multi-light source scheme is used to realize finished product defect detection. Specifically, the feeding positioning module and the discharging positioning module use open-face light to position the product, the first bottom surface detection module uses coaxial light to detect the pads and solder, the outer ceramic body inspection module and the inner ceramic body inspection module both use high-power coaxial light to detect the ceramic body; the first front surface detection module uses double-strip light to detect defects such as bumps and pits; the second front surface detection module uses coaxial light to detect defects such as sealing rings and leads; and the second bottom surface detection module uses ring light to detect leads. By constructing multiple stations, clear imaging of each area of the finished product is realized, and multiple light sources make the contrast of specific defects obvious, reducing the difficulty of detection.

[0117] In an embodiment, the automatic inspection equipment for CQFP ceramic shells further includes a cleaning device 600. The cleaning device 600 is arranged on the inner disc and is used to clean the boss detection tool 301 and the product. The cleaning device 600 can blow and clean the empty boss detection tool 301, and can also be arranged on the inner disc. Since the inner disc is higher than the outer disc by a preset height, the blowing direction is downward, thereby realizing blowing and cleaning of the front surface of the product, as shown in FIG. 8. Figure 9

[0118] In an embodiment, the automatic inspection equipment for CQFP ceramic shells further includes an air purification device for discharging foreign matter in the internal working environment of the automatic inspection equipment for CQFP ceramic shells.

[0119] For example, since the CQFP ceramic shell has high-density leads, in order to reduce the influence of foreign matter such as fibers on the inspection effect, the equipment is provided with multiple cleaning devices, the top of the equipment is provided with multiple FFU (Fan Filter Unit, fan filter unit) air purification devices, which can rapidly discharge foreign matter such as fibers in the equipment, and multiple blowing cleaning devices 600 are installed at the boss detection tool 301, further ensuring the accuracy of equipment inspection.

[0120] It can be seen that the present application provides an automatic inspection equipment for CQFP ceramic shells, which is composed of six hardware parts, i.e., the feeding and discharging mechanism 100 with a primary and secondary tray, the mechanical arm carrying mechanism 200, the rotary disc type station conversion mechanism 300, multiple visual positioning and inspection modules 400, the industrial computer 500, and the cleaning device 600, and is combined with a customized inspection software based on AI learning to automatically detect CQFP ceramic shells.

[0121] ​Through the combination of the defect automatic detection method fused with the AI technology, the multi-surface defect detection and the full-automatic detection, the product detection efficiency is improved, all defects are covered, and the inspection quality is ensured. On the one hand, all defects are ensured to be detected, and the delivery quality of the product is improved. On the other hand, the inspection efficiency is improved, and the inspection efficiency is more than 3 times of the manual inspection, thereby further meeting the increasing production demand

[0122] Referring to Figure 10 The embodiment of the application further provides an automatic inspection method for the CQFP type ceramic shell, which is applied to the automatic inspection equipment for the CQFP type ceramic shell in the above embodiment and comprises the following steps.

[0123] In step 701, a mother-daughter tray containing a preset number of CQFP type ceramic shells is placed into a storage port of a feeding mechanism.

[0124] For example, the mother-daughter tray containing the preset number of CQFP type ceramic shells is placed into the storage port a of the feeding mechanism, and three empty mother-daughter trays are placed into b of the feeding mechanism. The number of CQFP type ceramic shells in the mother-daughter tray is different each time, and is determined according to the detection batch and the type of the CQFP type ceramic shell.

[0125] In step 702, a mechanical arm carrying mechanism carries the CQFP type ceramic shell from the mother-daughter tray on the feeding mechanism to a convex post detection tool of a rotary table type station conversion mechanism.

[0126] For example, in step 702, the mechanical arm carrying mechanism 200 carries the CQFP type ceramic shell from the mother-daughter tray on the feeding mechanism to the convex post detection tool, which comprises the following steps: the feeding positioning module 401 photographs and positions the CQFP type ceramic shell in the feeding mechanism to obtain first photographing and positioning information, and sends the first photographing and positioning information to the industrial computer 500. The industrial computer 500 obtains first positioning data based on the first photographing and positioning information, and sends the first positioning data to the mechanical arm carrying mechanism 200. The mechanical arm carrying mechanism 200 carries the CQFP type ceramic shell from the mother-daughter tray on the feeding mechanism 101 to the convex post detection tool 301 according to the first positioning data in a preset order.

[0127] In step 703, the visual positioning and inspection module photographs and detects the CQFP type ceramic shell in the process that the mechanical arm carrying mechanism carries the CQFP type ceramic shell, and in the process that the rotary table type station conversion mechanism rotates the convex post detection tool on which the CQFP type ceramic shell is placed to the corresponding position of each detection module of the visual positioning and inspection module, to obtain photographing and detection information, and sends the photographing and detection information to the industrial computer.

[0128] Exemplarily, in step 703, the visual positioning and inspection module 400 performs photographic detection on the CQFP ceramic package during the process that the mechanical arm carrying mechanism 200 grabs the CQFP ceramic package and the process that the turntable type station conversion mechanism 300 rotates the boss detection tool 301 on which the CQFP ceramic package is placed to the corresponding position of each detection module of the visual positioning and inspection module 400, obtains photographic detection information, and sends the photographic detection information to the industrial computer 500, including:

[0129] During the process that the mechanical arm carrying mechanism 200 grabs the CQFP ceramic package, the first bottom surface detection module 402 performs photographic detection on the lead of the bottom surface of the CQFP ceramic package, obtains first photographic detection information, and sends the first photographic detection information to the industrial computer 500.

[0130] The turntable type station conversion mechanism 300 rotates the CQFP ceramic package to the outer side ceramic body detection module 403, the outer side ceramic body detection module 403 performs photographic detection on the outer side ceramic body of the CQFP ceramic package placed on the boss detection tool 301, obtains second photographic detection information, and sends the second photographic detection information to the industrial computer 500.

[0131] The turntable type station conversion mechanism 300 rotates the CQFP ceramic package to the first front surface detection module 404, the first front surface detection module 404 performs photographic detection on the bonding finger and the core area of the front surface of the CQFP ceramic package placed on the boss detection tool 301, obtains third photographic detection information, and sends the third photographic detection information to the industrial computer 500.

[0132] The turntable type station conversion mechanism 300 rotates the CQFP ceramic package to the second front surface detection module 405, the second front surface detection module 405 performs photographic detection on the sealing ring and the lead of the front surface of the CQFP ceramic package placed on the boss detection tool 301, obtains fourth photographic detection information, and sends the fourth photographic detection information to the industrial computer 500.

[0133] The turntable type station conversion mechanism 300 rotates the CQFP ceramic package to the inner side ceramic body detection module 406, the inner side ceramic body detection module 406 performs photographic detection on the inner side ceramic body of the CQFP ceramic package placed on the boss detection tool 301, obtains fifth photographic detection information, and sends the fifth photographic detection information to the industrial computer.

[0134] In the process that the mechanical arm carrying mechanism 200 classifies and carries the CQFP type ceramic shell from the boss detection tooling 301 to the sub-mother tray on the unloading mechanism 102, the second bottom surface detection module 408 detects the leads and the ceramic body of the bottom surface of the CQFP type ceramic shell to obtain sixth shooting detection information, and sends the sixth shooting detection information to the industrial computer 500.

[0135] In step 704, the industrial computer processes the shooting detection information to obtain the final detection result of the CQFP type ceramic shell, and sends the final detection result to the mechanical arm carrying mechanism.

[0136] For example, in step 704, the industrial computer 500 processes the shooting detection information to obtain the final detection result of the CQFP type ceramic shell, and sends the final detection result to the mechanical arm carrying mechanism, including:

[0137] The industrial computer 500 uses the inspection software to make defect judgment on the shooting detection information to obtain the detection result; the shooting detection information includes the first shooting detection information, the second shooting detection information, the third shooting detection information, the fourth shooting detection information, the fifth shooting detection information and the sixth shooting detection information; wherein the industrial computer 500 obtains the first detection result based on the first shooting detection information, obtains the second detection result based on the second shooting detection information, obtains the third detection result based on the third shooting detection information, obtains the fourth detection result based on the fourth shooting detection information, obtains the fifth detection result based on the fifth shooting detection information, and obtains the sixth detection result based on the sixth shooting detection information.

[0138] When the industrial computer 500 judges that the first detection result, the second detection result, the third detection result, the fourth detection result, the fifth detection result and the sixth detection result are all qualified, the industrial computer 500 obtains the final detection result as qualified, otherwise the final detection result is unqualified. The industrial computer 500 sends the final detection result to the mechanical arm carrying mechanism.

[0139] For example, the CQFP ceramic shell has many defect types and complex and variable conditions, and the occurrence position is irregular. For ceramic shell products, the same defect may have completely different shapes, sizes and colors on different parts and different products. At this time, an AI self-learning algorithm is introduced to realize automatic detection of such defects.

[0140] Specifically, the pictures of the products are divided into different regions based on the defect types, and different defect type detection parameter thresholds are configured based on the characteristics of the CQFP ceramic shell; the detection parameter threshold can include position detection parameter threshold, shape detection parameter threshold, area detection parameter threshold, etc. The defect region that exceeds the detection parameter threshold is marked. A large amount of AI defect learning and training is performed on the defects that are difficult to judge.

[0141] Exemplarily, different areas of the ceramic shell have different detection standards and contain different types of defects, so it is necessary to separately divide different detection areas and adopt independent partition inspection. Based on product partition, applicable defect detection types are added for each area, and detection parameter thresholds of different defect types are configured according to product characteristics.

[0142] For defects whose size and quantity are used as judgment basis, the original manual judgment cannot accurately judge the defect size. In equipment inspection, this type of defect is clearly marked with size, and the defect judgment basis is data-based.

[0143] In an embodiment, a large amount of AI defect learning and training is performed on the fuzzy judgment defects, including: defect detection on various defects of each detection part; the various defects can include gold loss, gold shortage, dirt, scratch, lead wire welding deviation, large solder, and protrusion, etc. The standard features of qualified products are learned through AI learning of a certain number of qualified product photos of each detection part; the standard features of defective products are learned through AI learning of a certain number of defective product photos of each detection part; the different features of the qualified product photos and the defective product photos are compared, and the different features are learned through AI; and the different features are used to represent the defect.

[0144] Exemplarily, according to the defects of the ceramic shell and the shape characteristics of the ceramic shell itself, a customized inspection software combining traditional template comparison and AI detection is customized for the appearance defect inspection of the ceramic shell. In actual application, the method of region marking, defect size marking, large amount of AI training, and database establishment is adopted to realize 100% detection of all defects of the ceramic shell.

[0145] Step 705, the mechanical arm conveying mechanism classifies and conveys the CQFP type ceramic shell to the child-mother type tray on the discharging mechanism according to the final detection result.

[0146] Exemplarily, the mechanical arm conveying mechanism classifies and conveys the CQFP type ceramic shell to the child-mother type tray on the discharging mechanism 102 according to the final detection result, including:

[0147] The rotary table type station conversion mechanism rotates the CQFP type ceramic shell to the discharging positioning module 407, the discharging positioning module 407 performs shooting positioning on the CQFP type ceramic shell on the boss detection tooling 301, obtains second shooting positioning information, and sends the second shooting positioning information to the industrial computer.

[0148] The industrial computer obtains second positioning data based on the second shooting positioning information, and sends the second positioning data to the mechanical arm conveying mechanism.

[0149] The mechanical arm conveying mechanism classifies and conveys the CQFP type ceramic shell to the child-mother type tray on the discharging mechanism 102 based on the second positioning data and the final detection result.

[0150] The mechanical arm carrying mechanism first picks up the CQFP type ceramic shell from the boss detection tool 301 based on the second positioning data, obtains the final detection result after the second bottom surface detection, and then carries the CQFP type ceramic shell to the sub-mother type tray on the discharging mechanism 102 according to the final detection result.

[0151] After detection by all detection modules of the visual positioning and inspection module, the products without errors are judged by the industrial computer, grabbed by the discharging mechanical arm to the qualified product discharging tray, and the products with problems are discharged to the unqualified product discharging tray. After all product inspection is completed, the operator or the mechanical arm discharges the products, and thus the detection process of the CQFP type ceramic shell is completed.

[0152] It can be seen that the application provides an automatic inspection equipment for CQFP type ceramic shells, which realizes automatic feeding and discharging through a sub-mother type tray and a mechanical arm, a rotary table type station is used for transferring between different detection stations, multiple visual inspection modules are used for shooting, and finally the unqualified products are removed through the combination of traditional visual template comparison and AI to complete the inspection. Through the combination of the defect automatic detection method of AI technology, multi-surface defect detection and full-automatic detection, the product detection efficiency is improved, all defects are covered, and the inspection quality is ensured.
