Description

Technical Field

[0001] The present invention relates to the technical field of equipment assembly, and in particular to an identity recognition vertical positioning PCB component assembly device. Background Art

[0002] With the development of the times, the role of solid-state drives in modern computer systems has become increasingly important. SSD components are generally composed of an upper board, a PCB board, and a lower board. The PCB board is the core part of the SSD and is mainly responsible for data processing and storage. The upper board usually serves as a protective layer, not only protecting the internal components from physical damage, but also providing structural support. In order to accurately assemble the SSD components, an assembly platform is required. The SSD components are placed on a carrier to ensure that each component maintains the correct position and angle during the assembly process, thereby improving assembly efficiency and ensuring assembly quality. Before assembling the SSD components, the carrier needs to be transported to the assembly platform. After assembly, the SSD components need to be screwed.

[0003] For example, the patent document with patent application number 202123073602.4 and announcement date 2022.08.19 discloses an automatic hard disk production system including: a rack, the rack including a first loading rail, a second loading rail and a third loading rail, the first loading rail being used to transport the outer shell, the second loading rail being used to transport the connector, and the third loading rail being used to transport the circuit board; and an assembly robot, the assembly robot being able to move relative to the rack to grab the circuit board on the third loading rail and place the circuit board in the outer shell on the first loading rail; the assembly robot being able to grab the connector on the second loading rail and transport the connector to the first loading rail, connecting the connector to the outer shell and the circuit board to form a hard disk module. The automatic hard disk production system of the present utility model technical solution can not only save human resources and improve product production efficiency, but also ensure high product quality.

[0004] The above document is provided with three loading tracks for providing the outer shell, connectors and circuit boards respectively, and then the above three are assembled separately by the assembly robot. Since the three parts have dimensional errors and shape deviations during the manufacturing process, the errors will accumulate or affect each other during the assembly of the robot, resulting in the inability to achieve the required accuracy when assembling the hard disk. Moreover, before assembly, the quality of the parts is not judged before assembly, and the yield rate cannot be guaranteed, which increases the cost of rework and maintenance. Since the quality of the hard disk is not judged during the assembly process of the robot, the hard disks need to be checked one by one later to ensure the yield rate. Summary of the Invention

[0065] Through holes 25 are provided on both sides of the second frame 2, and the through holes 25 are provided corresponding to the lower conveying device. Since the lower conveying device does not need to assemble the PCB assembly 26 on the carrier 23, it is only necessary to provide the through holes 25 so that the carrier 23 can be moved out of or into the lower conveying device.

[0068] A second locking and lifting mechanism 213 is provided in the middle of the second upper conveying mechanism 211.

The second inspection module 215 mainly captures the image of the PCB assembly 26 to be tested and detects the product quality of the PCB assembly 26 placed on the carrier 23. Before assembling the PCB assembly 26, the PCB assembly 26 can be moved under the inspection module 215, and the front of the PCB assembly 26 can be photographed. Then, the photographed picture is compared with the preset PCB assembly front picture, and whether the inserted PCB assembly is the front is determined based on the similarity of the two pictures.

[0073] The lower conveying mechanism 22 and the second upper conveying mechanism 211 have the same structure but opposite conveying directions. The structure of the limiting mechanism is the same as that of the second limiting mechanism. The limiting mechanism 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 set on 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.

Then the assembly device 3111 screws the fasteners on the PCB assembly. Finally, the third detection module 313 detects the position of the fasteners on the PCB assembly. The transportation direction of the assembly is defined 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. A three-dimensional moving module is provided on the third workbench 31. Block 311, an assembly device 3111 and a third detection module 313 are provided on the three-dimensional moving module 311, the assembly device 3111 and the third detection module 313 can be moved along the XYZ axis by the three-dimensional moving module 311, and the third upper conveying mechanism 314 conveys the carrier to a predetermined position. During the conveying process, the third identification module obtains information on the carrier, and a PCB assembly to be screwed into a fastener is placed on the carrier. The third limiting mechanism limits the moving position of the carrier. After the carrier stops at the predetermined area, the third locking lifting 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 fasteners such as screws. The third The detection module includes a camera 3131. The camera 3131 first determines the screw locking position of the component, and moves the assembly device 3111 to the feeding mechanism to take the screws. The assembly device 3111 passes through the pressure plate mechanism 312 to screw the component, 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 locked, the camera 3131 detects the screws in the component, and determines and records good and defective products. In this embodiment, the assembly device 3111 is an electric screwdriver, and the three-dimensional moving module 311 is a mechanism that can move along the XYZ direction of the third workbench 31, which is mainly achieved by driving a motor and a moving block.

[0075] like Figure 5 、 Figure 7 、 Figure 25 and Figure 26As 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 3122. The connecting frames 3121 are respectively connected to the first connecting plate and the second connecting plate. The pressing plate 3122 is fixedly set on the two connecting frames 3121.

[0076] Both the assembly platform machine and the fastening assembly machine are provided with a lower conveying device, which includes a lower conveying mechanism and an assembly platform limiting mechanism. The structures of the assembly platform limiting mechanism and the third limiting mechanism are the same as those of the second limiting mechanism. The lower 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 enable the driven mechanism to move away from or close to the active mechanism. The active mechanism and the driven mechanism on the assembly platform machine and the fastening assembly machine are arranged in the same manner as the active mechanism and the driven mechanism in the carrier elevator. The assembly platform machine and the fastening assembly machine have the same limiting mechanism. For example, if the second upper conveying mechanism and the third upper conveying mechanism 314 transport the carrier to the right, the lower conveying mechanism transports the carrier to the left. Therefore, when the lower conveying mechanism transports the carrier to one side, the carrier elevator can be used to receive the carrier, and the received carrier can be transported to the second upper conveying mechanism to complete the closed-loop transportation of the carrier.

[0077] A method for assembling a PCB component by vertically positioning the component through identification includes the following steps:

[0078] The S1 carrier elevator is used to lift the carrier to the second upper conveying device and move it between the second lower conveying device of the assembly platform to transport the carrier to the assembly platform for assembly. After assembly, the carrier is recovered and moved to the carrier elevator to realize closed-loop transportation;

[0079] S2 During the assembly process, the carrier is lifted by the second locking and lifting mechanism, and the second detection module is used to detect whether the PCB assembly placed on the carrier is placed correctly;

[0080] If no, then a prompt is given to replace the front and back sides of the PCB assembly; if the inspection is repeated and confirmed to be correct, the PCB assembly is transported to the fastening device and the process proceeds to step S23;

[0081] If yes, then release the second locking and lifting mechanism to allow the carrier to be transported to the fastening device;

[0082] S3 adjusts the spacing of the third conveying device to meet the requirements of different carrier widths, lifts the carrier to the corresponding position of the pressure plate mechanism through the third locking and lifting mechanism, and identifies the position of the screwed fasteners through the third detection module and assembles the fasteners according to the preset installation route. After the installation, the fastener installation status is inspected to determine whether it meets the requirements.

[0083] If the requirements are met, the product will proceed to the next process; otherwise, it will be classified as defective.

[0084] In this embodiment, the number of carriers is more than two, and the number of PCB components placed on the carrier in this embodiment is 4. The preset installation route is defined as assembling fasteners for multiple PCB components in a clockwise direction along the plane where the carrier is located, and an assembly drawing of multiple PCB components for assembling fasteners in a clockwise direction is pre-stored. During the assembly process, the starting position of the assembly device is preset, and then the image of the carrier where the first PCB component is located is obtained and then the position of the first PCB component on the carrier is determined. Then, when entering the second PCB component, the position of the second PCB component on the carrier is obtained. The installation route is determined based on the position of the first PCB component on the carrier and the position of the second PCB component on the carrier. The installation route is compared with the preset installation route to determine whether it meets the installation route requirements. If it meets the requirements, the next PCB component is installed. If it does not meet the requirements, an inspection is prompted. This can prevent the situation where a PCB component is missed after a PCB component is installed or another PCB component is repeatedly installed when installing fasteners, thereby further improving the accuracy of assembly.
