[0035] Solder paste printing is a crucial step in SMT (Surface Mount Technology) assembly, and its quality directly impacts the reliability and performance of the PCBA (Printed Circuit Board Assembly). A common method for inspecting solder paste printing is imprint inspection, which involves creating imprints on the solder paste (i.e., imprinted products) and then inspecting them using techniques such as visual inspection, optical projection inspection, X-ray inspection, or automated optical inspection. Imprint inspection can promptly identify solder paste problems, ensuring uniform application and correct placement, thereby guaranteeing product quality and customer satisfaction.

[0036] During the testing process, to ensure product quality, operators need to perform imprint checks on each batch of products separately. However, in practice, to improve efficiency, operators sometimes use the same imprinted product as different batches for multiple imprint checks, which affects the monitoring of chip quality.

[0037] Therefore, this application provides an imprint inspection device that can inspect imprinted products and prevent operators from using the same imprinted product as different batches of products for multiple imprint inspections, thereby ensuring quality control of different batches of products.

[0038] refer to Figure 1An imprint inspection device is shown, comprising a detection platform 10, a detection component 20, and a cleaning component 30. The detection platform 10 has an assembly slot 12 for mounting imprinted products. The detection component 20 is disposed on the detection platform 10 and above the assembly slot 12, and is used to inspect the imprinted products. The cleaning component 30 is disposed on the detection platform 10 and is used to clean the imprints on the imprinted products after inspection. Specifically, the detection component 20 is configured to prevent the inspection of the next imprinted product until the cleaning component 30 has completed cleaning the current imprinted product. This configuration prevents operators from using the same imprinted product for multiple imprint inspections across different batches, thus ensuring quality control of different batches of products.

[0039] In some embodiments, the testing platform 10 is provided with a detachable fixing fixture 11, and an assembly slot 12 is disposed on the fixing fixture 11. This arrangement allows the testing platform 10 to be adapted to different models of imprint products by replacing different fixing fixtures 11, which helps to improve the applicability of the device.

[0040] In some embodiments, the fixing fixture 11 is provided with a fixing member, and the fixing fixture 11 is detachably mounted on the testing platform 10 by means of the fixing member. For example, the fixing member may be a quick-release screw to facilitate the assembly and disassembly of the fixing fixture 11.

[0041] In some embodiments, the detection platform 10 is provided with a sensor for detecting whether the imprint product is installed in the assembly slot 12. For example, the detection platform 10 has a groove 13 located below the fixing fixture 11, and a sensor is installed in the groove 13. When the imprint product is installed in the assembly slot 12 of the fixing fixture 11 or when the fixing fixture 11 with the imprint product is installed on the detection platform 10, the sensor can detect whether the imprint product has reached the detection position.

[0042] In some embodiments, the cleaning component 30 includes a movable member 31, a cleaning member 32, and an identification unit. The movable member 31 is movably disposed on the detection platform 10, and the assembly slot 12 is located on the movement trajectory of the movable member 31. The cleaning member 32 is disposed on the movable member 31 and can clean the imprint of the imprinted product when the movable member 31 moves; that is, the cleaning member 32 can sweep across the surface of the imprinted product to clean the imprint on the surface of the imprinted product when the movable member 31 moves relative to the detection platform 10. The identification unit is disposed on the detection platform 10 and is configured to output a cleaning completion signal when the movable member 31 moves from an initial position to a set position (i.e., a position after the cleaning member 32 has swept across the imprinted product); that is, the identification unit can feed back a cleaning completion signal after the cleaning member 32 has swept across the imprinted product, so that the detection component 20 can detect the next imprinted product. This configuration ensures that the detection component 20 cannot detect the next imprinted product before the cleaning component 30 has completed cleaning the current imprinted product.

[0043] In some embodiments, the movement trajectory of the movable element 31 is a straight line. This configuration simplifies the movement path of the movable element 31, making its movement smoother. Of course, in other embodiments, the movement trajectory of the movable element 31 can also be an arc-shaped trajectory, etc.

[0044] In some embodiments, the detection platform 10 is provided with a track 14, and the movable component 31 is mounted on the track 14 and can move along the extension direction of the track 14. For example, the detection platform 10 is provided with two parallel linear guides, and the two ends of the movable component 31 are respectively mounted on the two linear guides. This arrangement can guide the movable component 31 and prevent the position of the movable component 31 from deviating and affecting the cleaning function. It should be understood that in specific implementations, the initial position and the set position of the movable component 31 can be the two ends of the track 14, respectively.

[0045] In some embodiments, the cleaning component 32 can be a rubber brush, which can break up the imprint on the product surface when it sweeps across it, thereby achieving the cleaning function. Of course, in other embodiments, the cleaning component 32 can also be a scraper, a scraper, or the like.

[0046] In some embodiments, the identification unit includes multiple identification switches 33, which are spaced apart between an initial position and a set position along the movement trajectory of the movable member 31. Each identification switch 33 outputs an identification signal after being triggered by the movable member 31. For example, the identification unit includes three identification switches 33, which are spaced apart along the extension direction of the track 14. The first identification switch 33 is located on one side of the assembly slot 12 and near one end of the track 14; the second identification switch 33 is located on the other side of the assembly slot 12 and near the other end of the track 14; and the third identification switch 33 is located on the other side of the assembly slot 12 and near the other end of the track 14. As the movable member 31 moves from one end of the track 14 to the other, it approaches the three identification switches 33 one by one, causing them to be triggered sequentially. The trigger signals of the three identification switches 33 can be used to trigger a cleaning completion signal or serve as the cleaning completion signal. This arrangement ensures that the movable member 31 scans the entire surface of the imprinted product before feeding back the cleaning completion signal, thus guaranteeing the cleaning effect.

[0047] In some embodiments, the cleaning assembly 30 further includes a handle 34 connected to the movable part 31. The handle 34 transmits power to the movable part 31 to move it. That is, during use, the operator can manually move the movable part 31 to remove the marks. Of course, in other embodiments, the handle 34 can be replaced with a mechanical drive mechanism, such as a pneumatic actuator or an electric actuator.

[0048] In some embodiments, the cleaning assembly 30 further includes an adsorption element disposed on the detection platform 10. The adsorption element is used to adsorb the movable part 31 to hold the movable part 31 in its initial position. For example, the adsorption element can be a magnet disposed inside or at the bottom of the detection platform 10. When the movable part 31 is in its initial position, the magnet can adsorb the movable part 31 to hold it in its initial position. This configuration allows the movable part 31 to be held in its initial position, so that the movable part 31 only needs to be moved to the set position each time cleaning is performed.

[0049] In some embodiments, the detection component 20 includes a camera 21 and a processor 22. The camera 21 is fixed to the detection platform 10 by a bracket and located above the assembly slot 12. The camera 21 is used to acquire image information of the imprinted product, such as... Figure 2 As shown. Processor 22 is electrically connected to camera 21. Processor 22 is used to analyze image information to determine whether the solder paste on the imprinted product is qualified. For example, processor 22 can use a threshold segmentation + color marking method to process and analyze the image information of the imprinted product to obtain a solder paste distribution image of the imprinted product, such as... Figure 3As shown, the image is then used to determine whether the solder paste distribution on the imprinted product is uniform. Of course, in other embodiments, the quality of the solder paste can also be assessed by its thickness, location, shape, etc.

[0050] In some embodiments, the detection component 20 further includes a light source 23 located below the camera 21. During use, the light source 23 can provide supplementary lighting to the camera 21 to improve image quality.

[0051] In some embodiments, the detection component 20 further includes a control button 24, which is electrically connected to the camera 21. The control button 24 is used to control the camera 21 to acquire image information of the imprinted product when operated by an operator. In specific settings, the control button 24 may be located on the detection platform 10.

[0052] In some embodiments, the detection component 20 further includes a memory electrically connected to the processor 22. The memory is used to store image information when the solder paste of the printed product is qualified. For example, during use, if the solder paste of the printed product is unqualified, the system can provide feedback to the operator so that the operator can adjust the printing parameters of the printing device or maintain the printing device. When the solder paste of the printed product is qualified, the system can store the image information of the printed product in the memory for later viewing.

[0053] In some embodiments, the detection component 20 further includes an alarm 25, which is electrically connected to the processor 22. The alarm 25 is used to sound an alarm when the solder paste on the imprinted product is defective. In specific configurations, the alarm 25 can be a light alarm 25, a sound alarm 25, or a combination of light and sound alarms. Of course, in specific implementations, the alarm 25 can also trigger alarms for other information, such as failure to clean the detected imprinted product or failure to store image information of the imprinted product.

[0054] In some embodiments, the detection component 20 further includes a display 26, which is electrically connected to the processor 22. The display 26 is used to prompt the user to proceed with the detection of the next imprint product when the solder paste of the imprint product is qualified. Of course, in specific implementations, the display 26 can also be used to display other information, such as the solder paste of the imprint product being unqualified or the image information of the imprint product failing to be stored.

[0055] The imprint inspection device of this application includes a cleaning component 30 and a detection component 20. The cleaning component 30 is used to clean the imprint of the imprint product after the inspection is completed. The detection component 20 cannot perform the inspection of the next imprint product before the cleaning component 30 completes the cleaning of the current imprint product. This enables the imprint inspection device to perform imprint inspection on the imprint products and prevents operators from using the same imprint product as different batches of products for multiple imprint inspections, thereby ensuring the quality monitoring of different batches of products.
