Description

Technical Field

[0001] This application relates to the field of PCBA manufacturing equipment technology, and in particular to a manufacturing equipment for PCBA and its operating method. Background Technology

[0002] Components on a PCBA (capacitors, chips, modules, etc.) require efficient heat dissipation to ensure functional stability and extend lifespan. Two-component thermally conductive adhesives are an ideal choice due to their good corrosion resistance and rapid thermal conductivity, but they need to be thoroughly mixed to effectively cure and achieve optimal thermal conductivity.

[0003] In existing two-component adhesive application processes, it is difficult to precisely control the amount of adhesive and ensure thorough mixing of the two components, affecting thermal conductivity and curing quality. Furthermore, manually tightening screws results in uncontrollable torque, impacting connection reliability and stress distribution, and poor positioning accuracy, easily leading to PCBA displacement from the heatsink housing. This displacement damages the contact interface of the thermally conductive adhesive, severely affecting heat dissipation efficiency and lifespan.

[0004] Modern industry has increasingly higher requirements for product quality, production efficiency and automation. Two-component thermally conductive adhesives are widely used, but the automation and precision of existing adhesive application and screw fixing processes urgently need to be improved.

[0046] For example, the clamping assembly 45 also includes a slide rail and a slider; the slide rail is arranged along the second direction and is connected to the mounting plate; the slider is slidably connected to the slide rail; the slider is connected to one end of the support arm 451, and the other end of the support arm 451 is connected to the fixed end of the third drive member 452.

[0053] For example, when the glue valve 61 is replaced with a mixing tube, the two components of glue are mixed through the mixing tube. The glue in the beginning is not mixed enough and needs to be discharged to the glue scraper bucket. After each glue application, the automatic program moves the glue nozzle 63 to the wire 65 of the glue scraper bucket to scrape the glue, so as to avoid glue residue on the glue nozzle 63 affecting the next glue application. When the equipment is paused due to special circumstances or resumed abnormally, the glue nozzle 63 is moved to the glue wiping position of the glue wiper 66, and the glue on the glue nozzle 63 is wiped by the non-woven cloth 67 to keep the glue nozzle 63 clean.

[0057] For example, the cylinder thrust forces the glue from the first glue container 72 and the second glue container 78 to their respective outlets. The outlets are connected to the glue inlet of the screw valve via piping, thus supplying the glue to the glue valve 61. It is important to note that the glue components must be filled according to the markings on the first glue container 72 and the second glue container 78; reversing the filling will cause irreversible damage to the screw glue valve 61 and the piping.

[0058] In the embodiments of this application, such as Figure 1-16 As shown, the two-station turntable 3 also includes a first driving component 31 and a turntable 32; both the operating position and the glue application position are equipped with positioning components 33; the positioning components 33 include a product positioning fixture 331, a diamond pin 332, a third positioning pin 333, a support pin 334, and a limiting post 335; two positioning fixtures 331 are spaced apart on the turntable 32; one end of the diamond pin 332, one end of the third positioning pin 333, one end of the support pin 334, and one end of the limiting post 335 are all connected to the positioning fixture 331, and the other ends of the diamond pin 332, the third positioning pin 333, the support pin 334, and the limiting post 335 are all in contact with the second workpiece; the fixed end of the first driving component 31 is connected to the station 2, and the output section of the first driving component 31 is connected to the turntable 32, and the turntable 32 is rotatably connected to the station 2 through the first driving component 31.

[0059] For example, the two-station turntable 3 also includes a protective baffle 34. When the turntable 32 rotates to the target position, the protective baffle 34 moves down, thereby reducing the impact of glue splashing on the workpiece at the operating position during the glue injection process.

[0060] For example, the second workpiece is placed manually on the positioning fixture 331 of the manual operation position. The sensor detects that it is in position. After the turntable 32 meets the rotation conditions, it rotates 180°. The manual operation position and the automatic glue application position are interchanged, and the mechanism of each station performs the next process operation.

[0061] In the embodiments of this application, such as Figure 1-16 As shown, the tightening mechanism 8 includes a vertical guide rod 81, a horizontal moving assembly 82, a balancer 83, a return block 84, and a tightening gun 85. One end of the vertical guide rod 81 is connected to the worktable 2, and the other end of the vertical guide rod 81 is connected to the balancer 83. The fixed end of the horizontal moving assembly 82 is connected to the outside of the vertical guide rod 81, and the movable end of the horizontal moving assembly 82 is connected to the tightening gun 85. The tightening gun 85 is configured to lock the first workpiece and the second workpiece. One end of the return block 84 is connected to the vertical guide rod 81, and the other end of the return block 84 is slidably engaged with the horizontal moving assembly 82. The return block 84 is configured to limit the movable end of the horizontal moving assembly 82.

[0062] For example, the tightening mechanism 8 is also provided with a tightening gun 85 controller, which can control the working state of the tightening gun 85.

[0063] For example, the tightening mechanism 8 can ensure the tightening verticality; the operator does not need to bear the weight of the tool, and the operator's wrist is also protected from the reaction force.

[0064] For example, this application also includes a touchscreen 10. The industrial touchscreen 10 provides an intuitive and easy-to-use human-machine interface. Through the graphical user interface, users can easily control the equipment, adjust parameters, monitor status, and perform other operations without the need for cumbersome physical buttons or knobs. Users can directly input data, commands, or text on the screen without an external keyboard or mouse. Simultaneously, the touchscreen 10 can also display real-time data, monitoring information, alarm status, etc., allowing users to understand the current status of the equipment or system. In summary, the industrial touchscreen 10, by providing an intuitive, flexible, and efficient human-machine interface, makes the operation and control of industrial equipment more convenient, faster, and more accurate, improving production efficiency and system reliability.

[0065] This invention provides an operating method for PCBAs, applicable to PCBA manufacturing equipment, comprising the following steps:

[0066] For workpiece loading, the first workpiece is first placed on the positioning mechanism 9 and precisely fixed by the first positioning pin 92;

[0067] The second workpiece is manually placed on the positioning component 33 of the operating position of the two-station turntable 3, and is positioned by the diamond pin 332, the support pin 334 and the limiting post 335.

[0068] Turntable 32 position switching: Activate the drive unit of the two-position turntable 3 to rotate turntable 32 180° and switch the loaded second workpiece from the operation position to the glue application position;

[0069] Automatic glue dispensing mechanism 5 drives glue dispensing assembly 6 to move to the coordinate position marked on the second workpiece: the first moving part 53 controls the horizontal mounting back plate 52 to move in the X direction; the second moving part 54 drives the glue valve moving back plate 56 to adjust in the Y direction; the third moving part 55 drives the glue valve 61 to be precisely positioned in the Z direction.

[0070] When the glue applicator mechanism 7 is activated: the first glue applicator drive 71 pushes the first sealing push block 75 to input the glue material in the first glue tank 72 into the glue valve 61 through the conversion connector; the second glue applicator drive 77 simultaneously pushes the second component of glue material to input the glue material in the second glue tank 78 into the glue valve 61 through the conversion connector; after the glue valve 61 mixes the glue material, it completes the glue application at the designated coordinate point of the second workpiece through the glue nozzle 63.

[0071] After the turntable 32 is reset and the workpiece is transferred, and the glue is applied, the two-station turntable 3 rotates 180° again to bring the second workpiece back to the operating position.

[0072] The transfer mechanism 4 operates as follows: the X-axis moving part 43 drives the clamping assembly 45 to move horizontally above the first workpiece; the Z-axis moving part 44 descends, and the gripper 453, in conjunction with the second positioning pin 454 and the guide pin 455, grasps the first workpiece; the clamping assembly 45 transfers the first workpiece onto the second workpiece that has been glued.

[0073] Once the screws are tightened, the tightening mechanism 8 is activated. After the tightening gun 85 is positioned by the lateral moving component 82, it drives the tightening gun 85 to lock the screws on the first and second workpieces and then remove the finished product.

[0074] Repeat the above steps to perform continuous operations.

[0075] For example, this application achieves simultaneous glue application and assembly through a two-station turntable 3: while glue is being applied on one side, manual loading and unloading can be performed on the other side; multiple sets of second positioning pins 454 and elastic elements 456 of the transfer mechanism 4 ensure that the workpiece is transferred without deviation. The glue pusher adopts a dual-drive design, thereby supporting precise mixing of single-component or two-component glues, and the mixing tube plug 62 prevents dripping; the return block 84 of the tightening mechanism 8 of this application limits the lateral travel and avoids overtravel collisions. The operation steps of this application fully utilize the multi-mechanism synergy advantages of the equipment, converting the glue application and curing waiting time into effective working time through cyclic workstations, improving production efficiency by more than 30%.
