Description

Technical Field

[0001] The present invention relates to the technical field of hard disk assembly, and in particular to an automatic assembly production line and method for solid-state hard disks based on image and identity recognition. Background Art

[0002] With the development of the times, the role of solid-state drives in modern computer systems is becoming increasingly important. In order to meet the market demand for high-performance storage devices and significantly improve production efficiency and product quality, a solid-state drive production line is needed. The production line should integrate an assembly platform and an accurate identification and positioning system to ensure that each solid-state drive component can be assembled in the correct position. After the assembly is completed, a series of processes such as screwing the PCB board assembly are carried out until the assembly is completed. The solid-state drive assembly is generally composed of an upper plate, a PCB board and a lower plate. The upper plate usually serves as a protective layer, and the lower plate provides structural support. In order to ensure the accurate assembly of the solid-state drive assembly, an assembly platform is required to place the solid-state drive assembly on a carrier to ensure that each component maintains the correct position during the assembly process, which not only improves the assembly efficiency but also ensures the assembly quality. For example, patent application number 201810312190.9, published on February 20, 2024, discloses a high-speed automatic labeling production line for solid-state drives. The production line includes a production conveyor belt, a fixture mounted on the production conveyor belt, a loading mechanism, a first fixture scanning mechanism, a first recovery mechanism, an automatic labeling mechanism, a visual inspection mechanism, a second fixture scanning mechanism, a second recovery mechanism, and a loading mechanism arranged sequentially along the production conveyor belt. The loading mechanism is equipped with a product scanning mechanism, and the fixture is provided with a fixture code. This structure aligns the original code of the memory bar with the fixture code on the production line, simplifying the production line and enabling fully automatic labeling of memory bars.

[0003] The above documents only disclose the labeling of assembled solid-state drives, but do not disclose the process of assembling the solid-state drive at the beginning and then fastening the solid-state drive after assembly. However, the assembly process of the solid-state drive is an important link. The order of components in the solid-state drive cannot be wrong, and after the correct assembly is completed, it is necessary to ensure that the components are firmly connected when fastening the solid-state drive. At the same time, relying solely on the label code for identification during the labeling process cannot solve the problem of accurately corresponding the label code to the position to be attached, and it is not convenient to recycle the carrier. Summary of the Invention

[0004] The present invention provides an automatic assembly production line and method for solid-state hard disks based on image and identity recognition, which has high assembly speed, high assembly quality and high production efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: an automatic assembly production line for solid-state hard disks based on image and identity recognition, which is used to assemble PCB board components into solid-state hard disks, including a carrier elevator, an assembly platform machine, a fastening assembly machine and a labeling machine arranged in sequence, wherein the carrier elevator, the assembly platform machine, the fastening assembly machine and the labeling machine are all provided with a two-layer conveying device, one of the two-layer conveying devices is used to convey the recovered carrier to the carrier elevator and move the carrier up and down to the assembly platform machine, and the assembly platform machine is used to identify the PCB board assembly. The PCB board assembly is assembled on the carrier according to the product situation and the preset installation path, and the carrier with the assembled PCB board assembly is transported to the fastening assembly machine, which is used to fasten the PCB board assembly on the carrier and identify whether the fastened PCB board assembly meets the fastening requirements, and move the fastened PCB board assembly that meets the requirements to the labeling machine, which is used to label the PCB board assembly that has passed the inspection, and during the labeling process, one side of the labeling machine is brought into contact with the position to be labeled and then labeling is performed. After labeling is completed, good products and defective products are sorted out.

[0006] The above setting integrates an automated system of carrier elevator, assembly platform machine, fastening assembly machine and labeling machine, which is specially used for the assembly, fixation and labeling of PCB board components. The carrier elevator is responsible for transporting the carrier to the assembly platform, and the carrier elevator, assembly platform, fastening assembly machine and labeling machine all have two-layer conveying devices, so that one layer can be used for material transportation, and the other side can transport the recovered carrier to the carrier elevator for lifting and moving to the assembly platform for material transportation. The assembly platform completes the assembly of PCB boards on the carrier, and during the assembly process, it detects whether the PCB board components entering the carrier are entered positively and installed in the preset path to prevent leakage or reverse installation. After that, the carrier with the PCB board is transferred to the fastening device for fixation, and the fastening assembly machine detects the fasteners on the PCB board and records the fastening. The good and defective products of the process are detected, and then the good products of the fastening process on the carrier are manually inspected for gaps, and the good and defective products of the gap process are recorded. The carrier with the PCB board components is moved to the labeling machine, and the labeling machine labels the good products of the gap process. After labeling is completed, the defective products in the fastening process and the defective products in the gap process are sorted into the defective area, and the labeled PCB board components are sorted into the good area; among them, the gap detection of the good products of the fastening process on the carrier can be performed by manual inspection of the gap, so as to detect the gap good and defective products of the good products in the fastening process; and the defective products in the fastening process and the defective products in the gap process are sorted into the defective area, and the labeled PCB board components are sorted into the good area. Manual sorting can also be used to sort the good and defective products, thereby realizing the installation and transportation of the solid-state hard disk, ensuring the provision of assembly efficiency and reliability.

The lifting mechanism 18 realizes the lifting movement of the mobile platform 12. The active mechanism 13 and the driven mechanism 14 are respectively arranged on the mobile platform 12. The active mechanism 13 is fixedly arranged at one end of the mobile platform 12, and the driven mechanism 14 is movably arranged on the mobile platform 12 through the guide assembly 15. The active mechanism 13 drives the driven mechanism 14 to move through the first rotating shaft 136. The distance adjustment mechanism 16 is used to adjust the distance between the active mechanism 13 and the driven mechanism 14. The guide assembly 15 is located between the active mechanism 13 and the driven mechanism 14. When the distance adjustment mechanism 16 is running, the guide assembly 15 is used to guide the moving direction of the driven mechanism 14 to ensure that it moves along a predetermined path.

[0010] like Figure 2-7As shown, the active mechanism 13 includes a first driving assembly, which includes a first driving member 131, a first driving wheel 132, a first conveyor belt 133 and a first driven wheel 134. The first driving member 131 is connected to the first driving wheel 132. The first driving member 131 is a driving motor. The output end of the first driving member 131 is rotatably connected to the first driving wheel 132 through a belt. The first driving wheel 132 is connected to one end of the first rotating shaft 136, and the other end of the first rotating shaft 136 is connected to the support seat 137. The first driven wheel 134 is arranged on both sides of the movable platform 12, and the first conveyor belt 133 is sleeved between the first driving wheel 132 and the two first driven wheels 134.

The recognition mechanism determines the position of component 26 in combination with the image of the correct component installation surface in the component comparison library. If the position is correct, the next component 26 is placed and the position of component 26 on the carrier is determined. During the placement of the next component 26, the second detection module 215 determines the position of the next component 26 in combination with the image of the correct component installation surface in the component comparison library. If the position is correct, the position of the next component 26 on the carrier and the position of the previous component 26 on the carrier are used to determine the component installation route. The component installation route is matched with the preset component installation route. If a match is found, the process proceeds to step S3.

[0027] S3: First, according to step S2, install the lower plate on the carrier 23 according to the preset component installation route, then install the PCB board on the lower plate according to the preset component installation route, and finally install the upper plate on the PCB board according to the preset component installation route; after all components are placed, the assembly is completed;

[0028] S4 moves the assembled component 26 to the fastening process, and the second detection module 215 identifies the position of the fasteners of the component 26 on the carrier 23, and compares it with the correct installation position of the fasteners in the component 26 comparison library, and performs the fastening process on the component 26 on the carrier according to the preset component installation route.

[0029] Step S2 includes: S21 places a lower plate in the assembly slot, and the second detection module 215 combines the component 26 to compare the correct installation surface picture of the component in the library to determine the position of the lower plate. If the position is correct, the next lower plate is placed and the position of the lower plate on the carrier is determined. If the position is incorrect, the position of the lower plate needs to be adjusted until the predetermined route is met.

[0030] S22 During the placement of the next lower plate, the second detection module 215 determines the position of the next lower plate in combination with the image of the correct installation surface of the component in the component comparison library. If the position is correct, the position of the next lower plate on the carrier and the position of the previous lower plate on the carrier 23 are used to determine the installation route of the lower plate, and determine whether the installation route of the lower plate matches the preset component installation route. If they match, proceed to step S3.

[0031] Step S3 includes: S31 After all the lower plates are placed, a PCB is placed on the upper surface of the lower plate. The second detection module 215 compares the component 26 with the correct installation surface image of the component in the library to determine the position of the PCB, and determines whether the PCB meets the preset route requirements. If so, step S32 is entered.

[0032] S32 After all PCB boards are placed, the upper board is placed on the upper surface of the PCB board. The second detection module 2152 determines the position of the upper board in combination with the component comparison library. The second detection module 215 compares the picture of the upper board with the picture of the correct installation of the preset components to determine whether the upper board is placed from the front and whether it is the upper board. At the same time, the position of the mounting slot on the carrier is determined by obtaining the picture of the mounting slot of the upper board on the carrier. The position is combined with the position of the previous upper board placed in the mounting slot on the carrier to form an installation route. For example, for the upper board on the carrier, It has four installation slots, and the clockwise direction of the plane where the carrier is located is the preset component installation route. For example, if the previous upper plate is the upper left corner of the carrier, and then the current upper plate is the upper right corner, the installation route is clockwise, which is the same setting as the preset component installation route. If the installation slot of the current upper plate is the upper left corner, it is determined that the starting point of the previous upper plate installation route is the upper left corner, which is a matching setting; the determination of the installation route of the PCB board and the lower plate and the comparison process with the preset installation route are the same as the determination of the upper plate installation route and the comparison process with the preset installation route.

[0033] S33 After all upper panels are correctly placed, the assembly of the components is completed.

[0034] By installing PCB components according to the preset installation path, problems such as missing or over-installation can be prevented, ensuring assembly reliability.

[0035] like Figure 21As shown, a lower-level conveying device is provided under the second workbench 24, and the lower-level conveying device includes a lower-level conveying mechanism 22 and a limiting mechanism 212. A lower-level conveying mechanism 22 and a limiting mechanism 212 are provided under the workbench 24. The lower-level conveying mechanism 22 can also transport the carrier 23, and the limiting mechanism 212 also controls the stopping position and moving range of the carrier 23 through physical contact.

[0036] The lower conveying mechanism 22 and the second upper conveying mechanism 211 have the same structure but opposite conveying directions. The limiting mechanism 212 is arranged on the other side of the stop position of the carrier 23. For example, the upper conveying mechanism 211 conveys the carrier 23 to the right, and the lower conveying mechanism 22 conveys the carrier 23 to the left. Therefore, when the lower conveying mechanism 22 conveys the carrier 23 to one side, the returned carrier 23 can be placed on the upper conveying mechanism 211 manually or using external equipment to complete the closed-loop conveying of the carrier 23. Since the conveying directions of the second upper conveying mechanism 211 and the lower conveying mechanism 22 are different, the position of the limiting mechanism 212 in the lower conveying mechanism 22 is changed. The limiting mechanism 212 is arranged on the other side of the stop position of the carrier 23, that is, when the carrier 23 stops, the limiting seat 2122 will abut against the side of the advanced workbench 24 of the carrier 23, thereby blocking the forward direction of the carrier 23 and limiting the carrier 23.

Finally, the third detection module 313 detects the position of the fasteners on the component, and defines the transportation direction of the component as the X-axis direction, the direction perpendicular to the X-axis direction on the horizontal plane is the Y-axis direction, and the direction perpendicular to the plane where the XY axes are located is the Z-axis direction. The three-dimensional moving module 311 can move in the X-axis, Y-axis and Z-axis directions, specifically by driving the motor driving module to slide on the guide rail. A three-dimensional moving module 311 is provided on the third workbench 31, and an electric screwdriver 3111 and a third detection module 313 are provided on the three-dimensional moving module 311. The electric screwdriver 3111 and the third detection module 313 can be moved along the XYZ axis by the three-dimensional moving module 311. The third upper conveying mechanism 314 conveys the carrier to a predetermined position. During the conveying process, the identification module obtains the information on the carrier. The PCB assembly to be screwed into the fastener is placed on the carrier. The limiting mechanism limits the moving position of the carrier. After the carrier stops at the predetermined area, the locking jacking mechanism lifts the carrier to the corresponding position of the pressing plate mechanism 312, so that the PCB assembly abuts against the pressing plate mechanism 312, and the feeding mechanism provides For fasteners such as screws, the detection module includes a camera 3131. The camera 3131 first determines the screw locking position of the component, moves the electric screwdriver 3111 to the feeding mechanism to take the screw, and the electric screwdriver 3111 passes through the pressure plate mechanism 312 to screw the component. The third detection module 313 is used to detect the picture of the PCB board component after tightening and compare it with the preset picture after tightening to determine whether the tightening requirements are met. If so, it enters the next program and adopts the diagonal screw locking method. If the component is provided with four screw locking positions, the screw is locked in the upper left corner first, and then the screw is locked in the lower right corner. After the four screws are tightened, the camera 3131 detects the screws in the component and determines and records good and defective products.

[0038] The third upper conveying mechanism 314 is provided with an active mechanism 13 and a driven mechanism 14. A first rotating shaft 136, a guide assembly 15 and a distance adjustment mechanism 16 are provided between the active mechanism 13 and the driven mechanism 14. The active mechanism 13 drives the driven mechanism 14 to rotate through the first rotating shaft 136. The distance adjustment mechanism 16 and the guide assembly 15 make the driven mechanism 14 move along the direction of the active mechanism 13. A limiting mechanism and a locking jacking mechanism are also provided.

[0039] like Figure 5 、 Figure 7 、 Figure 25 and Figure 26 As shown, the third upper conveying mechanism 314 is provided with two connecting plates, which are the first connecting plate and the second connecting plate respectively. The pressing plate mechanism 312 includes two connecting frames 3121 and a pressing plate assembly 3122. The connecting frames 3121 are respectively connected to the first connecting plate and the second connecting plate. The pressing plate assembly 3122 is placed on the two connecting frames 3121. Two connecting plates are provided on the third upper conveying mechanism 314. The connecting plates provide connection positions for the connecting frames 3121. The connecting frames 3121 are respectively connected to the first connecting plate and the second connecting plate. The two connecting frames 3121 provide connection positions for the pressing plate assembly 3122.

[0040] Both the assembly platform machine and the fastening assembly machine are provided with a lower-level conveying device, which includes a lower-level conveying mechanism and a limiting mechanism. The lower-level conveying mechanism is provided with an active mechanism and a driven mechanism. A first rotating shaft, a guide assembly and a distance adjustment mechanism are provided between the active mechanism and the driven mechanism. The active mechanism drives the driven mechanism to rotate through the first rotating shaft, and the distance adjustment mechanism and the guide assembly make the driven mechanism move away from or close to the active mechanism. For example, the second upper-level conveying mechanism and the third upper-level conveying mechanism 314 convey the carrier to the right, and the lower-level conveying mechanism conveys the carrier to the left. Therefore, when the lower-level conveying mechanism conveys the carrier to one side, a carrier elevator can be used to receive the carrier, and the received carrier can be conveyed to the second upper-level conveying mechanism to complete the closed-loop conveying of the carrier.

[0041] like Figure 27-36As shown, the labeling machine 01A includes a fourth frame 1A, a fourth workbench 11A is provided on the fourth frame 1A, a fourth upper conveying device 111A, a label feeding device 3A and a fourth three-dimensional mobile module 2A are provided on the fourth workbench 11A, the fourth upper conveying device 111A is used to transport a carrier, on which components to be labeled are placed, the fourth three-dimensional mobile module 2A is provided with a labeling device 22A, a fourth detection device 21A is provided on one side of the labeling device 22A, a fixed table 4A, a fourth mobile table 5A and a sixth detection device are provided on the fourth workbench 11A. After the fourth movable table 5A moves to the corresponding position of the label feeding device 3A to receive the label, the fourth detection device 21A detects the label on the fourth movable table 5A, and the labeling device 22A absorbs the label and moves to the corresponding position of the sixth detection device 112A. The sixth detection device 112A can detect the relative position between the label and the labeling device 22A and make adjustments. After the adjustment is completed, the label is attached to the component by the labeling device 22A. A label feeding device 3A is provided on the fourth workbench 11A. When the label feeding device 3A provides the label, the fourth movable table 5A detects the label on the fourth movable table 5A, and the labeling device 22A absorbs the label and moves to the corresponding position of the sixth detection device 112A. The sixth detection device 112A can detect the relative position between the label and the labeling device 22A and make adjustments. After the adjustment is completed, the label is attached to the component by the labeling device 22A. The fourth mobile platform 5A moves to the corresponding position to receive the label. After the label is placed on the fourth mobile platform 5A, the fourth mobile platform 5A moves to the side of the fourth upper conveying device 111A and the fixed platform 4A. The fourth three-dimensional mobile module 2A drives the fourth detection module to move above the label. The fourth detection module detects the label to ensure the integrity and correctness of the label. If the label does not meet the requirements, the fourth three-dimensional mobile module 2A will drive the labeling device 22A to absorb the non-compliant label to the fixed platform 4A. If the label meets the requirements, the fourth three-dimensional mobile module 2A will drive the labeling device 22A to absorb the non-compliant label. Take the label to the corresponding position of the sixth detection device 112A. The fourth three-dimensional mobile module 2A is preset with a position for labeling the component.

If the label is offset at the position of the labeling device 22A, the fourth three-dimensional mobile module 2A will obtain the compensation value and make corresponding adjustments, so that when the fourth three-dimensional mobile module 2A drives the labeling device 22A to label, the label can fall at the preset component labeling position, thereby eliminating the error of the labeling device 22A when sucking the label through the sixth detection device 112A.

[0042] The fourth frame 1 is also provided with a lower conveying device 12A, which is located below the fourth workbench 11A. The fourth frame 1A is provided with a fourth upper conveying device 111A and a lower conveying device 12A, both of which are used to convey carriers. The output and input of carriers can be completed by the different conveying methods of the fourth upper conveying device 111A and the lower conveying device 12A.

[0043] like Figures 28-29As shown, the fourth detection device 21A includes a first camera 211A, a mounting base 212A is arranged below the first camera 211A, a through hole 2121A is arranged in the middle of the mounting base 212A, the center of the through hole 2121A is arranged opposite to the center of the first camera 211A, side light sources 213A are arranged on both sides of the mounting base 212A, and a fourth detection device 21A is arranged on the fourth three-dimensional mobile module 2A. The fourth detection device 21A includes a first camera 211A, and the first camera 211A can detect the integrity and correctness of the label. Two side light sources 213A are arranged below the first camera 211A. The two side light sources 213A enable the first camera 211A to illuminate from the side when detecting the label to avoid strong reflections caused by front illumination, thereby obtaining clearer and higher contrast images.

[0044] The side light sources 213A are arranged facing each other. When the light sources shine from both sides, the shadows on the surface of the object will be dispersed and weakened, reducing the impact of the shadows on the imaging and making the image clearer.

[0045] like Figure 30-31As shown, the labeling device 22A includes a fourth drive 221A, a fifth drive 223A, a rotating seat 222A and a labeling seat 224A. The fourth drive 221A is connected to the fourth three-dimensional moving module 2A, and the output end of the fourth drive 221A is connected to the rotating seat 222A. One side of the rotating seat 222A is connected to the fifth drive 223A. The other side of the rotating seat 222A is hinged to one side of the labeling seat 224A. The other side of the labeling seat 224A is hinged to the output end of the fifth drive 223A. The fifth drive 223A is fixed on the labeling device 22A, and an abutment is further provided between the labeling seat 224A and the rotating seat 222A. The fourth three-dimensional moving module 2A is provided with a fourth drive 221A, and the output end of the fourth drive 221A is hinged to the rotating seat 222A. The fourth drive 221A can drive the rotating seat 222A to rotate in the horizontal direction, and is connected to the fifth drive 223A on one side of the rotating seat 222A. The other side of the rotating seat 222A is hinged to one side of the labeling seat 224A. The other side of the labeling seat 224A is connected to the output end of the fifth drive 223A. The rotation of the rotating seat 222A can drive the rotation of the labeling seat 224A, and the output end of the fifth drive 223A can make one side of the labeling seat 224A close to or away from the rotating seat 222A. An abutment is also provided between the labeling seat 224A and the rotating seat 222A, which can limit the labeling seat 224A when it approaches or moves away from the rotating seat 222A to prevent the labeling seat 224A from displacing too much and causing structural damage. A labeling suction cup 225A is provided below the labeling seat 224A, and a labeling roller 226A is provided on one side of the labeling suction cup 225A. The labeling roller 226A is located on the output end side of the fifth drive 223A. The labeling suction cup 225A is used to absorb the label, and one side of the label will contact the labeling roller 226A, and the labeling roller 226A is located on the output end side of the fifth drive 223A. The position of the labeling roller 226A can be adjusted by the fifth drive 223A so that the labeling roller 226A first contacts the component, and then the label is attached to the preset position of the component by moving the labeling roller 226A. In the process of the labeling roller 226A moving from one side of the label to the other side of the label, the labeling roller 226A can squeeze out bubbles when labeling to prevent bubbles in the label and ensure the reliability of labeling.

[0046] like Figures 32-33 As shown, the sixth detection device 112A includes a second camera 1121A, and the second camera 1121A is located on one side of the fourth upper conveying device 111A. The sixth detection device 112A detects the label at the labeling device 22A position, as shown in FIG. Figure 11As shown, if the solid line in the figure is the correct labeling position and the dotted line is the position of the label above the labeling position, the sixth detection device 112A determines the corresponding three-dimensional coordinate deviation value by obtaining the correct labeling position and the upper label position image, and can determine the compensation value by determining the position deviation value of the two center points O and O1, and then use the deviation value as the compensation value to move through the fourth three-dimensional moving module 2. If the label is offset in the position of the labeling device 22A, the fourth three-dimensional moving module 2A will obtain the compensation value and make corresponding adjustments, so that when the fourth three-dimensional moving module 2 drives the labeling device 22A to label, the label can fall on the preset component labeling position, thereby eliminating the error of the labeling device 22A when absorbing the label through the sixth detection device 112A. In this embodiment, the fourth three-dimensional moving module 2A includes an up and down moving module, a left and right moving module, and a front and back moving module. The moving modules are all moved by driving motors and slide rails, which will not be repeated here.

[0047] In addition, the sixth detection device 112A checks the correct labeling position and the position to be labeled, and rotates the position to be labeled to the correct labeling position through the rotating seat according to the deviation value between the position to be labeled and the correct labeling position. Figure 12 As shown in the figure, the solid line is the correct labeling position, and the dotted line is the position of the label above the labeling position. The sixth detection device 112A obtains the correct labeling position and the upper label position picture, and then determines the angle a between the two position axes, thereby determining the angle a as the angle compensation value, and then moves in three dimensions.

[0048] like Figure 34 As shown, the fourth movable platform 5A moves along the first track 113A and the second track 114A. The first track 113A and the second track 114A are provided on the fourth workbench 11A, so that it can move along the first track 113A and the second track 114A until it moves to the corresponding position of the label feeding device 3A.

[0050] The working method of the labeling machine includes the following steps:

[0051] S1 moves the fourth movable table 5A to one side of the label feeding device 3 and receives the label provided by the label feeding device 3A;

[0052] S2: The fourth mobile platform 5A moves to one side of the fourth upper conveying device and the fixed platform 4A, and the fourth three-dimensional mobile module 2A drives the fourth detection module to move above the label. The fourth detection module 21A detects the label. This is mainly done by collecting a picture of the label on the fourth mobile platform 5 and comparing it with a preset label picture. If the similarity meets the preset requirements, the label meets the requirements. If so, the process proceeds to step S3; otherwise, the label is transported to the unqualified product area.

[0053] S3 The fourth three-dimensional mobile module 2A will drive the labeling device to absorb the label to the corresponding position of the sixth detection device 112A. The sixth detection device 112A detects the position of the label in the labeling device. If the position and angle of the label in the labeling device are offset, the fourth three-dimensional mobile module 2A will obtain the position compensation value and make corresponding adjustments. The rotating seat will compensate the angle according to the angle offset value;

[0054] S4 One side of the labeling seat 224A contacts the preset component so that one side of the label is attached to the preset component, and the fourth three-dimensional moving module 2 drives the labeling roller to move to achieve flat attachment of the label to the preset component.
