Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a dual-track AOI detection system. Background Art

[0002] After upstream processing, HTCC products need to enter the AOI inspection camera for inspection. During the inspection process, the position of the HTCC products needs to be kept accurate and sufficient stability needs to be maintained during the inspection process. Since HTCC products are transmitted through the assembly line, the products need to be separated from the assembly line during inspection to maintain the stability of the inspection. However, the current lifting device generally adopts the method of cylinder lifting or motor lifting. On the one hand, the Z-axis direction is lifted by the motor and the cylinder, and the installation space of the lifting device needs to be reserved, resulting in a larger overall equipment volume. On the other hand, the cylinder or motor drive mechanism lifted vertically has poor stability, which will affect the effect of photo inspection; in addition, the existing AOI inspection device generally adopts single-station work, which is inefficient. Although there are also multi-station ones, it is necessary to design multiple handling and transmission routes, resulting in higher equipment costs. Summary of the invention

DETAILED DESCRIPTION

[0028] Example 1

[0029] Combination Figures 1 to 5 As shown, this embodiment provides a dual-track AO I detection system, including a frame 1, a transplanting system 2 arranged on the frame 1, and a detection system, wherein the detection system includes a first detection component 3 and a second detection component 5 arranged side by side, wherein the first detection component 3 and the second detection component 5 are both provided with a conveying line 31, a lifting and conveying component 33 arranged along the transmission direction of the conveying line 31 and located below the conveying line 31, and an AO I device 4 arranged above the conveying line 31; wherein the transplanting system 2 is suitable for transferring the product 6 to the waiting station 32 on the first detection component 3 and the second detection component 5 respectively; the lifting and conveying component 33 includes a slide rail 331 extending along the transmission direction of the conveying line 31, a first driving device 332, a lifting device 333 suitable for sliding on the guide rail, and a detection platform 34 arranged on the lifting device 333, wherein the first driving device 332 is suitable for driving the lifting device 333 to transfer the waiting station 32 to the detection station; The lifting device 333 includes a second driving device 3333, an inclined rail 3334 inclined upward along the transmission direction of the conveying line 31, and a slider 3335 slidably arranged on the inclined rail 3334. The detection platform 34 is arranged on the slider 3335. The driving device is suitable for driving the inclined rail 3334 to move toward the transmission direction of the conveying line 31 so that the slider 3335 slides relative to the inclined rail 3334, thereby allowing the detection platform 34 to drive the product 6 to be lifted and lowered; the AIO device 4 is suitable for taking pictures after the product 6 is lifted to a predetermined height, so as to perform image detection of defects on the surface of the product 6.

[0030] Continue to combine Figures 1 to 5 As shown, in this embodiment, the transplanting system 2 includes a transverse moving component 21, and a transplanting platform 22 is provided on the transverse moving component 21 for transporting the product 6 from the upstream end to the first detection component 3 and the second detection component 5 respectively; another transplanting system 2 is provided at the rear end of the detection system for transporting the product 6 on the first detection component 3 and the second detection component 5 to the downstream end. Here, a conveying line 23 is provided on the transplanting platform 22, and the conveying line 23 is connected to switch between the first detection component 3 and the second detection component 5 under the drive of the transverse moving component 21, and when it is located at the position of the first detection component 3, its other end is docked with the conveying line 23 at the upstream end, so that the product 6 at the upstream end is transported to the transplanting platform 22, and then according to the working progress of the first detection component 3 and the second detection component 5, the product 6 is moved to the workstation of the first detection component 3 and the second detection component 5 respectively, and docked with the waiting workstation 32 on the first detection component 3 and the second detection component 5, so as to transport the product 6 to the waiting workstation 32. Preferably, a barcode scanner 24 is provided above the transplanting platform 22, and the barcode scanner 24 is suitable for scanning the product 6 when the product 6 moves to the transplanting platform 22 to obtain the corresponding product 6 information, and transmit the product 6 information to the control system, so as to allocate the position of the product 6 through the control system. In addition, in this embodiment, another transplanting system (not shown) is provided on the first detection component 3 and the second detection component 5, and the structure of the transplanting system is the same as the aforementioned transplanting system 2, which is used to transport the product 6 detected on the detection component to the downstream end, and the products 6 of the two stations can be respectively transferred to the downstream end through a transplanting platform. That is to say, in this embodiment, a transplanting system 2 provided at the front end of the detection system can realize the function of one-to-two or even one-to-many transmission, and another transplanting system provided at the rear end of the detection system can realize the function of two-to-one transmission or many-to-one transmission; the equipment can be effectively simplified, the equipment cost can be reduced, and the time gap of the detection process can be fully utilized to make the overall rhythm smooth.

[0031] Combination Figures 3 to 5As shown, the detection system includes at least a first detection component 3 and a second detection component 5. The structures of the first detection component 3 and the second detection component 5 are basically the same. For the convenience of explanation, the first detection component 3 is taken as an example for explanation. The first detection component 3 includes a conveying line 31, a lifting conveying component 33 and an AO I device 4. Among them, a waiting station 32 is arranged at the front end of the conveying line 31 for docking with the conveying line 23 on the transplanting platform 22, and for importing the product 6 from the transplanting platform 22; an independent conveying component 321 is arranged on the waiting station 32; it should be noted that the conveying component 321 of the waiting station 32 is provided with an independently controlled motor for controlling the conveying time of the product 6. When the first detection component 3 needs to be fed, the motor rotates to drive the conveying component 321 to transport the product 6 of the waiting station 32 to the conveying line 31 at the rear end. The rear end of the conveying line 31 extends to the rear end of the AO I device 4, so as to export the product 6 to the transplanting platform 22 at the rear end of the detection system after the detection is completed. The conveying line 31 is provided with two parallel conveyor belts on the left and right, and the frame edge of the product 6 is suitable for being placed on the conveyor belt, so as to be transported to a predetermined position. It should be noted that the structures of the conveying line 23, the conveying assembly 321, and the conveying line 31 in this embodiment can be the same.

[0032] The lifting and conveying assembly 33 is arranged below the conveying line 31 and is located between two conveyor belts. It includes a slide rail 331 extending along the transmission direction of the conveying line 31, a first driving device 332, a lifting device 333 suitable for sliding on the guide rail, and a detection platform 34 arranged on the lifting device 333. The first driving device 332 is suitable for driving the lifting device 333 to transfer the product 6 transferred from the waiting station 32 to the detection station; here, the first driving device 332 can adopt a linear motor or a ball screw mechanism to drive the lifting device 333 to slide on the guide rail, thereby transferring the product 6 to the detection position.

[0033] The lifting device 333 includes a second driving device 3333, an inclined rail 3334 inclined upward along the transmission direction of the conveying line 31, and a slider 3335 slidably arranged on the inclined rail 3334. The detection platform 34 is arranged on the slider 3335. The driving device is suitable for driving the inclined rail 3334 to move toward the transmission direction of the conveying line 31 so that the slider 3335 slides relative to the inclined rail 3334, thereby allowing the detection platform 34 to drive the product 6 to be lifted and lowered; the second driving device 3333 can adopt a ball screw assembly to achieve precise control of the lifting height. During operation, the second driving device 3333 drives the inclined rail 3334 to move toward the rear end of the detection system, so that the slider 3335 is at the lowest position of the inclined rail 3334. At this time, the height of the detection platform 34 is lower than the height of the conveying line 31. Then the lifting device 333 moves to the front end of the conveying line 31 under the control of the first driving device 332 and aligns with the bottom of the product 6. Then the inclined rail 3334 is driven by the second driving device 3333 to move toward the front end of the detection system. Since the slider 3335 does not move relative to the product 6 in the horizontal position, when the inclined rail 3334 moves toward the front end of the detection system, the inclined rail 3334 will gradually lift the slider 3335 until the product 6 enters the detection platform 34 and is fixed. By means of relative movement between the inclined rail 3334 and the slider 3335, the water level position of the slider 3335 is kept unchanged. Driving the inclined rail 3334 to drive the lifting and lowering of the slider 3335 can improve the stability of the lifting process. At the same time, since the entire conveying lifting assembly is horizontally arranged below the conveying assembly line 31, the installation space of the equipment can be saved.

[0034] In this embodiment, the lifting device 333 is further provided with a base 3331, and a plurality of lifting rails 3332 connected to the detection platform 34 are provided on the base 3331 to limit the displacement of the slider 3335 in the horizontal direction when the inclined rail 3334 moves relative to the slider 3335, and to enable the detection platform 34 to be lifted and lowered in the vertical direction. That is, the lifting rail 3332 is provided to limit the displacement of the slider 3335 in the horizontal direction relative to the base 3331, and when the inclined rail 3334 slides, the slider 3335 slides relative to the inclined rail 3334 to achieve lifting and lowering.

[0035] The detection platform 34 is provided with a porous vacuum ceramic plate 341 for adsorbing the surface of the product 6; positioning pins 342 are provided on both sides of the detection platform 34 for cooperating with the positioning holes provided on the product 6 to position the product 6. Here, a relatively uniform adsorption surface can be formed on the surface by the porous vacuum ceramic plate 341 to reduce damage to the surface of the product 6. The porous vacuum ceramic plate 341 is connected to a vacuum device to form a vacuum suction force on its surface. In a preferred embodiment, a plurality of triangular positioning holes 61 are provided on one side of the product 6, and a plurality of square positioning holes 62 are provided on the opposite side; when the product 6 is placed on the conveying line 31, the positioning holes are exposed between the two conveyor belts, so that the positioning pins 342 on the detection platform 34 can be inserted into the positioning holes. The triangular positioning hole 61 and the square positioning hole 62 are respectively adapted to match the positioning pins 342 on both sides of the detection platform 34. The width of the positioning hole is greater than the positioning pin 342 so as to facilitate the insertion of the positioning pin 342. A mechanical positioning method can be used for preliminary positioning so that the positioning pin 342 is inserted into the positioning hole. For example, when the product 6 enters the conveying line 31, the product 6 is stopped at a set position by a limit device, and then the detection platform 34 is moved to a corresponding position so that the positioning pin 342 is roughly aligned with the position of the positioning hole, and then the detection platform 34 is lifted to allow the positioning pin 342 to enter the positioning hole to complete the preliminary positioning. In this embodiment, the triangular positioning hole 61 is in the shape of an isosceles triangle, and its symmetry line is parallel to the transmission direction of the transmission line. The front end of the detection platform 34 in the conveying direction is provided with two positioning cylinders 343, and the positioning cylinders 343 are provided with positioning blocks 344. The positioning blocks 344 are suitable for extending when the product 6 is not placed on the detection platform 34, and retracting after the product 6 is placed to push the product 6 to move backward, so that the positioning pins 342 contact the edge of the positioning hole, and limit the relative displacement of the product 6. That is to say, when the positioning blocks 344 are extended, a large placement space is left on the detection platform 34 for the product 6 to be placed. After the product 6 is placed and initially positioned, the positioning blocks 344 are driven to retract to push the product 6 to move in the same direction as the retraction direction of the positioning blocks 344, until the positioning pins 342 are limited by the inner wall of the positioning hole on one side close to the positioning blocks 344, so that the product 6 can be accurately positioned through the positioning holes and the positioning blocks 344. In this embodiment, by respectively providing the triangular positioning holes 61 and the square positioning holes 62 on both sides of the product 6, on the one hand, the position of the product 6 can be prevented from being fooled, and on the other hand, the product 6 can be accurately positioned. The positioning hole in the shape of an isosceles triangle can prevent the product 6 from shifting after precise positioning, which is beneficial to the accuracy of subsequent detection.

[0036] The AOI device 4 includes a mobile system 42 and a photographing device 41 arranged on the mobile system 42, and the mobile system 42 is suitable for driving the photographing device 41 to move above the product 6 to take photos of the product 6 at multiple positions. The photographing device 41 of the AOI device 4 here is an existing AOI inspection camera, which can be driven by the mobile system 42 to move on the surface of the product 6 to obtain images of the product 6 at different positions. For example, multiple photos can be taken at different positions for identification and comparison, and then judged according to the algorithm. The specific shooting and identification method can adopt existing technologies, which will not be elaborated here. The mobile system 42 can adopt existing transverse movement devices or XY axis motion mechanisms, etc., which will not be repeated here.

[0037] When the product 6 is inspected, the positioning cylinder 343 drives the positioning block 344 to release the limit on the product 6, and then the lifting device 333 drives the inspection platform 34 to descend, so that the product 6 falls onto the conveying line 31 and is transferred to the downstream end through the rear end transplanting system.

[0038] Through this solution, the stability of detection can be achieved, the detection efficiency can be improved, and the equipment cost can be saved.

[0039] Example 2

[0040] The present invention also provides a detection method of a dual-track AOI detection system, using the dual-track AOI detection system described above, the steps are:

[0041] S1, the transplanting system 2 transports the product 6 from the upstream end to the waiting station 32 of the first detection component 3 and the second detection component 5 respectively;

[0042] S2, the first detection component 3 and the conveying and lifting component in the second detection component 5 move the lifting device 333 to the bottom of the waiting station 32, at which time the positioning block 344 extends out of the front edge of the detection platform 34; then the lifting device 333 drives the detection platform 34 to rise, so that the positioning pin 342 on the detection platform 34 is inserted into the positioning hole of the product 6 to achieve preliminary positioning; when the detection platform 34 is lifted to a preset height, the positioning block 344 retracts to act on the front side of the product 6, pushing the product 6 to move in the same direction as the retraction direction of the positioning block 344, until the positioning pin 342 is limited by the inner wall of the positioning hole close to the positioning block 344, and the positioning block 344 cooperates with the positioning pin 342 to accurately position the product 6; after the positioning is completed, a vacuum is applied to the porous vacuum ceramic plate 341 to adsorb the product 6 on the detection platform 34;

[0043] S3, after the positioning of the product 6 is completed, the AOI device 4 moves above the product 6 to take multiple photos of the product 6, and analyzes and identifies defect information of the product 6;

[0044] S4. After the detection is completed, the products 6 on the first detection component 3 and the second detection component 5 are unloaded through the transplanting system arranged at the rear end.

[0045] This solution adopts a unique dual-station design, which greatly improves the detection efficiency. In the same time period, two HTCC products 6 can be tested at the same time, which effectively shortens the production cycle and meets the needs of large-scale production. By setting a flat-lying lifting device 333, the installation space of the lifting device 333 can be reduced, and the support method is more stable, reducing the detection error. Furthermore, by setting a unique positioning structure, the accuracy of positioning the product 6 can be improved, and the porous vacuum ceramic plate is used for adsorption and fixation, which can reduce damage to the product 6. Through this solution, the detection efficiency and accuracy of the detection can be improved.

[0046] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.

[0047] The above description of the drawings used in the implementation manner only illustrates certain embodiments of the present invention and should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without paying creative work.
