Description

[0001] This application claims priority to Chinese Patent Application No. 2024112284900, filed on September 3, 2024, entitled “A Multi-Station Patch Mounting Machine”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of pick and place machine technology, and more particularly to a multi-station pick and place machine. Background Technology

[0003] Pick and place machines are key pieces of equipment in the electronics manufacturing industry used to automatically mount electronic components onto PCBs. They achieve precise positioning and placement of components through a high-speed moving placement head and a precision vision alignment system.

[0004] Chinese patent publication CN116322019A discloses a pick-and-place machine, which achieves automated placement by setting up a series of components including a feeding assembly, a carrier assembly, a transfer assembly, a feeding assembly, and a placement assembly, as well as a rail-front imaging assembly, a rail-front blowing assembly, and a rail-front correction assembly. It also improves placement accuracy and product quality through a series of detection and correction measures. However, while this pick-and-place machine achieves automated placement, it mainly focuses on single-station operation, failing to fully utilize production time and resulting in slow production efficiency. Although the aforementioned pick-and-place machine improves placement accuracy through the rail-front imaging and correction assemblies, it still cannot meet today's high-precision requirements.

Detailed Implementation

[0018] like Figures 1-15 As shown, a multi-station chip mounter includes a frame 1, two blue film loading mechanisms symmetrically arranged on the left and right sides of the frame 1, a mounting platform 3 between the two blue film loading mechanisms, and a feeding mechanism 4 on the front side of the frame 1 for transporting chips from the blue film loading mechanisms to the mounting platform 3. Each blue film loading mechanism has a chip vision positioning mechanism on one side for visual positioning of the chips. The mounting platform 3 includes a substrate loading mechanism 6 for placing the substrate to be mounted, a correction mechanism 7 for correcting the deviation of the chips transported by the feeding mechanism 4, a pre-mount vision positioning mechanism 8 for pre-mounting visual positioning of the chips on the correction mechanism 7 and the substrate to be mounted, and a mounting mechanism 9 for transporting the corrected chips to the substrate loading mechanism 6 for mounting.

[0019] As described above, in this invention, the entire mounting process, from blue film loading to chip mounting, is highly automated, reducing manual intervention, lowering the risk of human error, and alleviating the workload of operators. Specifically, by designing two symmetrical blue film loading mechanisms on the left and right sides, parallel operation of dual or multiple workstations is achieved. This allows for simultaneous loading and pre-processing of chips on two or more blue films, significantly improving overall production efficiency and capacity. The chip vision positioning mechanism next to each blue film loading mechanism accurately identifies and positions the chip, ensuring its precise position in subsequent processes. The pre-mount vision positioning mechanism 8 further ensures precise alignment between the chip and the substrate to be mounted, thereby improving mounting accuracy and reliability. The correction mechanism 7 automatically corrects deviations before the chip is transported to the mounting platform, eliminating potential positional deviations during transport and ensuring the chip is mounted in optimal condition, thus improving product mounting quality and consistency.

[0020] like Figure 1 , Figure 2 as well as Figure 3 As shown, in specific implementation, the two blue film loading mechanisms are divided into a left blue film loading mechanism 201 and a right blue film loading mechanism 202. Each blue film loading mechanism includes: a first Y-axis linear module 21 set in the frame 1, a first movable seat 22 driven by the first Y-axis linear module 21 to move back and forth, and a first X-axis linear module 23 installed on the first movable seat 22. The first X-axis linear module 23 is driven to a first rotating platform 25 that can rotate through a second movable seat 24. The rotating platform 25 is provided with a tray rack 26 for placing wafer trays on it. A pin module 27 is provided below the tray rack 26. The tray rack 26 is provided with a connecting part 261 connected to the rotating platform 25, and multiple tray frames 262 with circular cutouts are formed by extending outward from the center of the connecting part 261.

[0021] As described above, by setting up two blue film loading mechanisms on the left and right respectively, dual-line or parallel loading of wafer trays is achieved, significantly improving the automation level and operational efficiency of the production line. Each blue film loading mechanism is independently equipped with a first X-axis linear module and a first Y-axis linear module, as well as a rotatable platform, enabling each mechanism to flexibly move and position the wafer tray in two-dimensional space, meeting the requirements for precise alignment and rapid tray change under different process requirements. The tray frame is securely connected to the rotating platform through a connecting part, and adopts a tray frame with circular cutouts, which not only ensures the stability of the structure but also facilitates the subsequent ejection of chips by the ejector module. Moreover, the setting of multiple tray frames allows other trays to be used as spare wafer trays, so that when a wafer tray is used up, it can be directly replaced by rotation, improving production efficiency.

[0022] like Figure 3As shown, in a specific implementation, the ejector module 27 includes: a first longitudinal drive assembly 271 mounted longitudinally on the frame 1; a first transverse drive assembly 272 driven by the first longitudinal drive assembly 271 and capable of longitudinal movement; a third movable seat 273 driven by the first transverse drive assembly 272 and capable of transverse movement; a first vertical drive assembly 274 mounted vertically on the third movable seat 273; and a fourth movable seat 275 driven by the first vertical drive assembly 274 and capable of vertical movement. An ejector seat 276 is mounted on the fourth movable seat 275. A first roller 277 is connected below the 6, and a first cam 278 is provided below the first roller 277 to cooperate with it to realize the lifting and lowering movement of the cam. The fourth movable seat 275 is also equipped with a first rotary motor 279 to drive the first cam 278 to rotate. The top of the fourth movable seat 275 protrudes a first extension 2751 towards the side close to the ejector seat 276. The ejector seat 276 is provided with a second extension 2752 that is vertically opposite to the first extension 2751. A first spring 2753 is connected between the first extension 2751 and the second extension 2752.

[0023] As described above, the ejector module achieves flexible movement in three-dimensional space through multi-stage drive components: a first longitudinal drive component, a first transverse drive component, and a first vertical drive component. This facilitates precise positioning of the ejector base and its ejector pins to designated positions below the wafer tray, meeting precise operation requirements under different processes. The cam's lifting motion is achieved through the cooperation of a first roller, a first cam, and a first rotary motor. This mechanical structure provides a stable lifting path, reducing vibration and offset during movement, and ensuring the stability and accuracy of the ejector pins during lifting. The integration of multi-stage drive components allows for automated operation of the ejector module's lifting motion through electrical control, improving the automation level and production efficiency of the production line. The first spring connecting the first extension and the second extension acts as a buffer and shock absorber. When the ejector base and its ejector pins contact the wafer tray, the spring absorbs some of the impact force, reducing damage to the wafer tray and the ejector pins themselves, while also improving operational smoothness.

[0024] like Figures 4 to 7 As shown, in a specific implementation, the feeding mechanism 4 includes a horizontal support 41 disposed in front of the two blue film feeding mechanisms, and a second X-axis linear module 42 mounted on the horizontal support 41. The second X-axis linear module 42 is driven and connected to a plurality of suction nozzle modules for picking up chips from the blue film feeding mechanism 2. The plurality of suction nozzle modules include at least: a left suction nozzle module 4301, a right suction nozzle module 4302, and a standby suction nozzle module 4303 between the left suction nozzle module 4301 and the right suction nozzle module 4302.

[0025] Each nozzle module includes: a fifth movable seat 431 that is driven by a second X-axis linear module 42 and can move laterally; a first Z-axis linear module 432 mounted on the fifth movable seat 431; and a nozzle mounting seat 433 that is driven by the first Z-axis linear module 432 and can move up and down. The nozzle mounting seat 433 is driven by a first multi-dimensional fine-tuning component 434 to connect to a plurality of first strip nozzles 435 that can be finely adjusted left and right and up and down.

[0026] The first multi-dimensional fine-tuning component 434 includes: a first mounting base 4341 mounted on the nozzle mounting base 433 and a second mounting base 4342 located below the first mounting base 4341. The first mounting base 4341 includes: a first vertical wall portion 43411 that is fitted and connected to the nozzle mounting base 433, and a first longitudinal wall portion 43412 and a second longitudinal wall portion 43413 extending rearward from the upper and lower ends of the first vertical wall portion 43411, respectively. 43412 has a first mounting hole 434120, and a first clearance space 41414 is formed between the first vertical wall portion 43411, the first longitudinal wall portion 43412, and the second longitudinal wall portion 43413; the first multi-dimensional fine-tuning component 434 further includes: a second rotary motor 4343 mounted on the top of the first mounting base 4341 through the first mounting hole 434120, a second cam 4344 rotated by the second rotary motor 4343, and a cam that cooperates with the second cam 4344 to achieve a convex shape. The second roller 4345 connected by wheel drive, the first transverse guide rail 4346 mounted on the rear side of the first longitudinal wall portion 43412, the first steering seat 4347 moving laterally along the first transverse guide rail 4346, and the third vertical drive assembly 4348 mounted on the second mounting base 4342; a part of the first steering seat 4347 is a first horizontal plate portion 43471 disposed in the first clearance space 43414 and connected to the first mounting base 4341 via the first connecting rod 4349, and the other part The first vertical plate portion 43472 extends downward from the end of the first horizontal plate portion 43471 and is mounted on the first horizontal guide rail 4346. The rear side of the first vertical plate portion 43472 is recessed with multiple first guide grooves 434720. The third vertical drive assembly 4348 is driven to be connected to a third roller 4351 that can be mounted and rolled up and down along the first guide grooves 434720 via a first connector 4350. Each first connector 4350 is equipped with a first strip-shaped suction nozzle 435.

[0027] As described above, the feeding mechanism in this case, by setting up a left suction nozzle module, a right suction nozzle module, and a standby suction nozzle module, achieves the ability to perform parallel or sequential operations at multiple workstations, significantly improving the efficiency of chip picking and transfer, reducing waiting time, and increasing overall production efficiency. The first multi-dimensional fine-tuning component in each suction nozzle module allows for fine-tuning of the first strip-shaped suction nozzle left and right, and up and down, ensuring that the nozzle can accurately align with the chip position, accurately picking up chips even with slight deviations, thereby reducing defect rates and scrap rates. Through the driving of the second X-axis linear module and the first Z-axis linear module, as well as the precise control of the second rotary motor and the third vertical drive component, the entire feeding process is automated and intelligent, improving work efficiency. Specifically, the first multi-dimensional fine-tuning component, through the cam transmission of the second cam and the second roller, the cooperation of the first transverse guide rail, and the guidance of the first connecting rod and the first guide groove, ensures the stability and accuracy of the suction nozzle during the fine-tuning process. At the same time, the overall structure is compact, which helps save space and reduce equipment costs.

[0028] like Figure 6 and Figure 7 As shown, in a specific implementation, the second mounting base 4342 is connected to a first auxiliary guide seat 436 for assisting the smooth lifting and lowering of the first strip-shaped suction nozzle 435. The first auxiliary guide seat 436 has a first connecting plate portion 4361, a second connecting plate portion 4362, and a hollow mounting portion 4363 formed between the first connecting plate portion 4361 and the second connecting plate portion 4362. The first connecting plate portion 4361 is fitted and connected to the first mounting base 4341 and is disposed below the first steering seat 4347. The second connecting plate portion 4362 has a first mounting groove 43620 recessed in its middle, a first inclined surface 43621 extending obliquely from the middle to the left and backward on its left side, and a first inclined surface 43621 extending obliquely from the middle to the right and backward on its right side. A second inclined surface 43622, symmetrical to the first inclined surface 43621, extends obliquely. A plurality of first auxiliary rollers 43623 are evenly arranged on the first inclined surface 43621. A plurality of second auxiliary rollers 43624, symmetrical to the first auxiliary rollers 43623, are evenly arranged on the second inclined surface 43622. The plurality of first auxiliary rollers 43623 and the plurality of second auxiliary rollers 43624 form a first guide rolling channel 43625 for the first strip-shaped suction nozzle 435 to move along its guide. A second connector 43626 is installed in the first mounting groove 43620, and a limiting through-hole 436260 with a through hole is protruding rearward from the second connector 43626 for the first strip-shaped suction nozzle 435 to pass through.

[0029] As described above, in this application, the first auxiliary guide seat, through the close-fitting connection between the first connecting plate and the first mounting seat, and its location below the first steering seat, ensures the vertical stability of the entire auxiliary guide structure, thereby improving the stability of the first strip-shaped suction nozzle during lifting and lowering, and reducing errors caused by shaking or offset. A first guide rolling channel is formed by multiple first auxiliary rollers and multiple second auxiliary rollers, providing a smooth and precise guide path for the first strip-shaped suction nozzle. Simultaneously, the use of rollers instead of direct sliding contact significantly reduces wear between the first strip-shaped suction nozzle and the guide structure, contributing to its service life. The first and second inclined surfaces provide a certain tilt angle to the first guide rolling channel, allowing for better adaptation to different angles or slightly tilted installation environments, enhancing the adaptability and flexibility of the entire system. The second connector and its limiting through-part installed within the first mounting groove further limit the positioning of the first strip-shaped suction nozzle, making its suction more stable.

[0030] like Figure 8 As shown, in specific implementation, the chip visual positioning mechanism is divided into a left chip visual positioning mechanism 501 and a right chip visual positioning mechanism 502. Each chip visual positioning mechanism includes: a vertical frame 51 set on the frame 1, a mounting plate 52 installed on the top of the vertical frame 51 and located above the blue film feeding mechanism 2, a second longitudinal drive component 53 mounted longitudinally on the mounting plate 52, a second lateral drive component 54 driven by the second longitudinal drive component 53 and capable of longitudinal and lateral movement, a fourth vertical drive component 55 driven by the second lateral drive component 53 and capable of lateral movement, and a sixth movable seat 56 driven by the fourth vertical drive component 55 and capable of lifting and lowering movement. A first visual camera 57 is installed on the sixth movable seat 56, and a first light source 59 is also installed on the sixth movable seat 56 through a vertical connector 58.

[0031] The substrate loading mechanism 6 includes: a second Y-axis linear module 61 mounted on the frame 1, a second X-axis linear module 62 driven longitudinally by the second Y-axis linear module 61, and a substrate carrier 63 for placing the substrate to be mounted therein, driven laterally by the second X-axis linear module 62. The substrate carrier 63 is symmetrically provided with a plurality of second auxiliary rollers 631 on its left and right sides to form a second guide rolling channel 632 for the substrate to be mounted to enter along its guide.

[0032] As described above, each chip vision positioning mechanism includes a second longitudinal driving component, a second lateral driving component, a fourth vertical driving component, a first vision camera, and a first light source. These components allow for flexible movement in three-dimensional space, facilitating precise capture and identification of the chip's position and ensuring accurate subsequent mounting. The design of the left and right chip vision positioning mechanisms further enhances the system's stability and positioning accuracy, enabling the simultaneous processing of multiple chips and making it suitable for scenarios requiring complex mounting operations. The combined use of the second Y-axis linear module and the second X-axis linear module of the substrate loading mechanism enables precise and stable movement of the substrate carrier on the horizontal plane. This ensures the substrate enters the mounting area smoothly and accurately, reducing mounting problems caused by substrate position deviations. Furthermore, it enables automated loading, reducing manual handling time and improving production efficiency.

[0034] As described above, the correction mechanism in this application, through the longitudinal movement of the third Y-axis linear module and the lateral, longitudinal, and rotational movements of the second multi-dimensional fine-tuning component, enables precise adjustment of the chip in three-dimensional space. This ensures that the chip's position, angle, and orientation meet high-precision requirements before mounting, effectively improving the accuracy and success rate of mounting. Furthermore, the left and right correction mechanisms in this application can operate independently, handling chips on both sides of the substrate respectively, improving the equipment's flexibility and processing capacity.

The third longitudinal wall portion 95412 has a second mounting hole 954120. A second clearance space 95414 is formed between the second vertical wall section 95411, the third longitudinal wall section 95412, and the fourth longitudinal wall section 95413; the third multi-dimensional fine-tuning component 954 further includes: a third rotary motor 9543 mounted on the top of the third mounting base 9541 through a second mounting hole 954120; a third cam 9544 rotated by the third rotary motor 9543; a fourth roller 9545 cooperating with the third cam 9544 to achieve cam transmission connection; and a second... A transverse guide rail 9546, a second steering seat 9547 that moves laterally along the second transverse guide rail 9546, a second auxiliary guide seat 9548 mounted on the fourth mounting seat 9542, and a fifth vertical drive assembly 9549 mounted on the second auxiliary guide seat 9548; a portion of the second steering seat 9547 is a second horizontal plate portion 95471 disposed in the second clearance space 95414 and connected to the third mounting seat 9541 via a second connecting rod 9550, and another portion is a fifth vertical drive assembly 9549 extending downward from the end of the second horizontal plate portion 95471 and mounted on the fourth mounting seat 9542.

[0038] The second auxiliary guide seat 9548 is used to assist the smooth lifting and lowering of the second strip-shaped suction nozzle 9553 and is installed on the rear side of the second strip-shaped suction nozzle 9553. The second auxiliary guide seat 9548 has a third inclined surface 95481 and a fourth inclined surface 95482 extending obliquely to the left and right sides and rearward from the center of the second strip-shaped suction nozzle 9553, respectively.

The multiple third auxiliary rollers 95483, multiple fourth auxiliary rollers 95484 and fifth auxiliary rollers 95486 form a third guide rolling channel 95487 for the second strip-shaped suction nozzle 9553 to move along its guide limit.

[0039] As described above, the mounting assembly in this application utilizes a third multi-dimensional fine-tuning component to achieve fine-tuning of the pressing component in the left-right and up-down directions, ensuring accurate mounting of the chip to the designated position on the substrate. Through the third rotary motor, third cam, and fourth roller configuration of the third multi-dimensional fine-tuning component, rotational motion is converted into lateral motion via cam transmission, enabling the lateral movement of the second steering seat. Cam transmission offers high efficiency and rapid response to control signals, improving mounting speed. The fifth vertical drive assembly drives the second strip-shaped suction nozzle to roll up and down along the second guide groove via a third connector, ensuring stability and accuracy during the lifting process. Meanwhile, the third and fourth inclined surfaces on the second auxiliary guide seat, along with the third and fourth auxiliary rollers mounted thereon, together with the fifth auxiliary roller, form the third guide rolling channel. This channel can limit and guide the second strip nozzle from the left, right, and rear sides, providing precise guidance and limiting for the second strip nozzle. This prevents offset and tilting during the placement process, which is beneficial for the placement assembly to achieve high-precision chip placement and meet the stringent requirements of modern electronics manufacturing for product quality and production efficiency.

[0041] As described above, the dispensing assembly uses a fourth rotary motor to drive the dispensing bracket to rotate, and a fifth rotary motor to drive the dispensing head via a synchronous pulley assembly. This enables multi-degree-of-freedom movement of the dispensing head, allowing for precise control of the dispensing position, angle, and speed, thereby improving dispensing accuracy and consistency. The third vision camera in the dispensing vision positioning assembly uses a sixth vertical drive assembly to achieve lifting and lowering movement, enabling visual positioning of the substrate at different heights, thus improving positioning accuracy and ensuring the precision of the dispensing position.
