Description

Technical Field

[0001] This utility model relates to the field of chip mounters, and more specifically, to a fully automatic chip mounter with a dual-nozzle feeding mechanism. Background Technology

[0002] Fully automatic placement machines are used to achieve high-speed, high-precision, fully automatic placement of components. They are the most critical and complex equipment in the entire SMT production process. Placement machines are the main equipment in the SMT production line. They have evolved from early low-speed mechanical placement machines to high-speed optical alignment placement machines, and are developing towards multi-functional, flexible, and modular designs.

[0003] Chinese invention patent CN117412579B discloses a patch feeding device, specifically a patch feeding device including a vibratory feeder mechanism, a cam mechanism, a product testing mechanism, and a carrier feeding mechanism. The cam mechanism includes several suction nozzles that adsorb products output by the vibratory feeder mechanism and rotate them onto the product testing mechanism for testing. Products that pass the test are transported to the carrier feeding mechanism. The carrier feeding mechanism includes a Y-axis carrier module and a first X-axis carrier module and a second X-axis carrier module disposed on the Y-axis carrier module. The first X-axis carrier module includes a first carrier, and the second X-axis carrier module includes a second carrier. The first and second carriers move independently along the X-axis direction, and the carrier module drives the first and second carriers to move simultaneously along the Y-axis direction. This invention achieves cyclic feeding of products through a first carrier and a second carrier, which greatly improves the working efficiency of the equipment and extends the service life of the cam mechanism. The single-nozzle feeding system used in this solution has a slow feeding rate, which cannot meet the current production needs. Furthermore, since a single nozzle requires a higher cam running speed and more rotations, the wear between components is accelerated. To improve the machine's lifespan and production efficiency, a fully automatic chip mounter with a dual-nozzle feeding mechanism is proposed to solve the above problems. Utility Model Content

[0004] To overcome the slow feeding rate and rapid wear between components in existing technologies, and the fact that a single nozzle requires a higher cam speed and more rotations, further accelerating wear, this utility model provides a fully automatic pick-and-place machine with a dual-nozzle feeding mechanism. The machine includes a pick-and-place machine with a base plate fixedly mounted on its worktable. A first drive motor is fixedly mounted on the top of the base plate. The first drive motor is coaxially connected to a first drive wheel. A first transmission belt is movably mounted outside the first drive wheel. A first driven wheel is movably mounted inside the first transmission belt. A switching shaft screw is fixedly mounted inside the first driven wheel.

[0005] A second drive motor is fixedly installed on the top of the mobile module base plate. The second drive motor is coaxially connected to a second drive wheel. A second transmission belt is movably installed on the outside of the second drive wheel. A second driven wheel is movably installed inside the second transmission belt. A second lead screw is fixedly installed inside the second driven wheel. A first carrier platform is engaged with the outside of the second lead screw.

[0006] A third drive motor is fixedly installed on the top of the mobile module base plate. A third drive wheel is coaxially connected to the third drive motor. A third transmission belt is movably installed on the outside of the third drive wheel. A third driven wheel is movably installed inside the third transmission belt. A third lead screw is fixedly installed inside the third driven wheel. A second carrier platform is engaged with the outside of the third lead screw.

[0007] The top of the mobile module base plate is fixedly installed with a sliding guide rail, and the bottoms of the first and second vehicle platforms are slidably connected to the sliding guide rail.

[0008] The chip mounter has two motors fixedly installed on its top. Both motors are coaxially connected to cams, and each of the two cams has a number of dual-nozzle feed heads on its top.

[0009] The tops of the first and second vehicle platforms are provided with material troughs at equal intervals, and the dual suction nozzles are adapted to the shape of the material troughs. The material troughs are two sets that are staggered.

[0010] Preferably, the chip mounter is fixedly equipped with a material storage mechanism and a vibratory feeder mechanism on its top. The material storage mechanism is used to store raw materials and feed them to the vibratory feeder mechanism. The vibratory feeder mechanism feeds two raw materials to the main turntable mechanism evenly at the same time.

[0011] The main turntable mechanism is the main mechanism for conveying raw materials to each workstation. It works in conjunction with the vibratory feeder mechanism to transport the raw materials conveyed by the storage mechanism to each unit.

[0012] Preferably, a first positioning mechanism is fixedly installed on the top of the chip mounter. The first positioning mechanism is used to calibrate the positions of the two raw materials transported by the main turntable mechanism.

[0013] The first positioning mechanism is the mechanism that performs the first calibration.

[0014] Preferably, a testing mechanism is fixedly installed on the top of the chip mounter, and the testing mechanism is used to test the electrical parameters of the two calibrated raw materials.

[0015] Preferably, an imaging mechanism and a first NG discharge mechanism are fixedly installed on the top of the placement machine. The imaging mechanism is used to simultaneously perform image detection on two raw materials, and the NG raw materials that fail the test are discharged through the first NG discharge mechanism.

[0016] Preferably, a polarity rotation mechanism and a second positioning mechanism are fixedly installed on the top of the chip mounter. The polarity rotation mechanism is used to rotate the two raw materials independently to ensure that the two raw materials with different directions are rotated to the same direction and then transported to the second positioning mechanism. The second positioning mechanism performs position calibration on the two raw materials at the same time.

[0017] Preferably, a second NG discharge mechanism and an optical fiber detection component are fixedly installed on the top of the pick-and-place machine. The second NG discharge mechanism is used to detect whether there is raw material on the two nozzles and discharge NG raw material at the same time.

[0018] Preferably, an image correction NG nesting platform and a PCB placement correction platform are fixedly mounted on the top of the placement machine.

[0019] The image correction NG nesting platform calibrates the raw material products, while the PCB placement correction platform calibrates the position of the PCB board.

[0020] Beneficial effects:

[0021] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0022] (1) By installing multiple sets of double suction nozzle feeding heads on the cam, and combining the first carrier platform driven by the second drive motor and the second carrier platform driven by the third drive motor, the raw materials of the product are transported continuously by the staggered arrangement of the double slots on the carrier. At the same time, the first carrier platform and the second carrier platform are switched by the first motor, thereby ensuring the continuous feeding of the main turntable mechanism. Compared with the single suction nozzle cam feeding speed, the feeding speed is doubled, and the rotation speed of the cam component and the number of rotations required are reduced. While improving production efficiency, the wear and tear between the cam components is reduced, and the stability and service life of the equipment are improved.

[0023] (2) The Y-axis and X-axis motion modes are driven by the first drive motor, the second drive motor and the third drive motor. The combination of the transmission belt and the lead screw realizes the power transmission in a narrow space. The uninterrupted feeding function of the carrier is realized by switching the power transmission of the module. The dual-axis movement and sliding guide rail are combined with different installation positions to realize the conveying of raw materials and products. The three drive modules adopt a separate modular design, which can greatly shorten the assembly time and assembly difficulty, and facilitate maintenance and loading and unloading.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows:

[0045] like Figures 1 to 9As shown, a fully automatic pick-and-place machine with a dual-nozzle feeding mechanism includes a pick-and-place machine 1. A base plate 100 is fixedly mounted on the top of the pick-and-place machine 1. A first drive motor 2 is fixedly mounted on the top of the base plate 100. A first drive wheel 21 is coaxially connected to the first drive motor 2. A first transmission belt 22 is movably mounted on the outside of the first drive wheel 21. A first driven wheel 23 is movably mounted inside the first transmission belt 22. A switching shaft screw 24 is fixedly mounted inside the first driven wheel 23. A connecting slide plate 3 is engaged with the outside of the switching shaft screw 24. A switching shaft guide rail 4 is fixedly mounted on the top of the base plate 100. The bottom of the slide plate 3 is slidably connected to the switching shaft guide rail 4, and the top of the connecting slide plate 3 is fixedly installed with the mobile module base plate 6. When the first drive motor 2 drives the first active wheel 21 to rotate, the first transmission belt 22 and the first driven wheel 23 will drive the switching shaft screw 24 to rotate, thereby causing the connecting slide plate 3, which is engaged with the outside of the switching shaft screw 24, to move in the Y-axis direction. In conjunction with the switching guide rail 4, the two ends of the connecting slide plate 3 can slide together, which can form a power transmission in a narrow space. In conjunction with the alternating feeding first carrier platform 75 and second carrier platform 85, the material can be fed continuously, which significantly improves work efficiency.

[0046] In addition, a second drive motor 7 is fixedly installed on the top of the mobile module base plate 6. The second drive motor 7 is coaxially connected to a second drive wheel 71. A second transmission belt 72 is movably installed on the outside of the second drive wheel 71. A second driven wheel 73 is movably installed inside the second transmission belt 72. A second lead screw 74 is fixedly installed inside the second driven wheel 73. The first carrier platform 75 is externally engaged with the second lead screw 74. A third drive motor 8 is fixedly installed on the top of the mobile module base plate 6. The third drive motor 8 is coaxially connected to a third drive wheel 81. A third transmission belt 82 is movably installed on the outside of the third drive wheel 81. A third driven wheel 83 is movably installed inside the third transmission belt 82. A third lead screw 84 is fixedly installed inside the third driven wheel 83. The first carrier platform 75 and the second carrier platform 85 are engaged with each other. The top of the mobile module base plate 6 is fixedly installed with a sliding guide rail 9. The bottoms of the first carrier platform 75 and the second carrier platform 85 are slidably connected to the sliding guide rail 9. The second drive motor 7 drives the second drive wheel 71, the second transmission belt 72, the second driven wheel 73, and the second lead screw 74 to rotate, so that the first carrier platform 75, which is engaged with the outside of the second lead screw 74, moves in the X-axis direction, thereby changing the position of the first carrier platform 75 below the dual suction head 93 to realize the loading function. The second carrier platform 85 also moves in the X-axis direction by being driven by the third drive motor 8. The cooperation between them can achieve uninterrupted feeding effect, and the efficiency of the dual suction head 93 is also higher than that of the single suction head, further improving production efficiency.

[0047] The chip mounter 1 has two motors 91 fixedly mounted on its top. Both motors 91 are coaxially connected to cams 92. The top of each cam 92 is provided with a number of dual-nozzle feed heads 93. The tops of the first carrier platform 75 and the second carrier platform 85 are provided with material slots at equal intervals. The shape of the dual-nozzle feed heads 93 is adapted to the shape of the material slots. The material slots are arranged in two sets in a staggered manner. The material slots on the first carrier platform 75 and the second carrier platform 85 are staggered and the spacing is the same to adapt to the position of each dual-nozzle feed head 93 on the cam 92.

[0048] like Figures 8 to 10 As shown, a material storage mechanism 10 and a vibratory feeder mechanism 11 are fixedly installed on the top of the pick-and-place machine 1. The material storage mechanism 10 stores raw materials and feeds them to the vibratory feeder mechanism 11. The vibratory feeder mechanism 11 simultaneously and evenly feeds two raw materials to the main turntable mechanism 5. A first positioning mechanism 15 is fixedly installed on the top of the pick-and-place machine 1. The first positioning mechanism 15 is used to calibrate the position of the two raw materials transported by the main turntable mechanism 5. A testing mechanism 16 is fixedly installed on the top of the pick-and-place machine 1. The testing mechanism 16 is used to perform electrical parameter testing on the two calibrated raw materials. An imaging mechanism 17 and a first NG discharge mechanism 18 are fixedly installed on the top of the pick-and-place machine 1. The imaging mechanism 17 is used to simultaneously perform image detection on the two raw materials. NG raw materials that fail the test are discharged through the first NG discharge mechanism 18. A polarity rotation mechanism 14 and a polarity rotation mechanism 15 are fixedly installed on the top of the pick-and-place machine 1. The second positioning mechanism 13 and the polarity rotation mechanism 14 are used to rotate the two raw materials independently to ensure that the two raw materials with different directions are rotated to the same direction and then conveyed to the second positioning mechanism 13. The second positioning mechanism 13 performs position calibration on the two raw materials at the same time. The top of the pick and place machine 1 is fixedly installed with the second NG discharge mechanism 12 and the fiber optic detection component. The second NG discharge mechanism 12 is used to detect whether there is raw material on the two nozzles and discharge the NG raw material at the same time. The two main turntable mechanisms 5 are respectively equipped with independent storage mechanism 10, vibratory feeder mechanism 11, first positioning mechanism 15, testing mechanism 16, imaging mechanism 17, second positioning mechanism 13, polarity rotation mechanism 14 and first positioning mechanism 15. The raw material receiving effect of the first carrier platform 75 and the second carrier platform 85 can achieve double the production efficiency.

[0049] It should be noted that the top of the pick and place machine 1 is fixedly equipped with an image correction NG feed platform 19 and a PCB placement correction platform 20. The first positioning mechanism 15 and the second positioning mechanism 13 adopt laser positioning, but other positioning methods can also be used. The image mechanism 17 is equipped with a high-definition camera to detect the appearance and quantity of the raw materials. The finished products will be transported by the main turntable mechanism 5 to the first carrier platform 75 and the second carrier platform 85. The first NG feed mechanism 18 and the second NG feed mechanism 12 discharge unqualified raw materials.

[0050] like Figure 14 , Figure 16 and Figure 17 As shown, the staggered design of the material trays of the second carrier platform 85 and the first carrier platform 75 can perfectly adapt to the feeding of the dual-nozzle feeding head 93. If a single-row parallel design is adopted, when the equipment changes to PCBs with different pitches for production, the vibratory feeder mechanism 11, the main turntable mechanism 5, the testing mechanism 16, the imaging mechanism 17, the polar rotation mechanism 14, and other mechanisms all need to be designed and replaced according to the different pitches of PCB product parts. Therefore, when changing to different pitches of products, a large number of parts will be disassembled and replaced, which is very time-consuming and reduces production efficiency. When a double-row parallel structure is adopted, when the equipment changes to PCBs with different pitches, the vibratory feeder mechanism 11 cannot perform the single-track simultaneous material picking function according to the product pitch. Therefore, the staggered design of the loading carrier is suitable for the mounting needs of PCB products with different pitches, and the equipment can achieve production without replacing a large number of mechanism parts.

[0051] Working principle: The raw materials from the storage mechanism 10 are screened and transported to the front end of the vibratory feeder mechanism 11 via the vibratory feeder mechanism 11. The raw materials are arranged in a staggered manner. The main turntable mechanism 5 picks up the raw materials from the front end of the vibratory feeder mechanism 11 and transports them to the first positioning mechanism 15 for correction. The corrected raw materials are then transported to the testing mechanism 16 for electrical parameter testing. After testing, the raw materials are transported to the imaging mechanism 17. At this station, NG (non-compliant) raw materials are discharged. If a single NG raw material is found, both products on the nozzle will be discharged together. If the raw materials are qualified, their appearance will be inspected at this station using imaging equipment. The inspected raw materials are then sent to the polarity rotation mechanism 14. Non-conforming raw materials are discharged through the first NG discharge mechanism 18. The polarity rotation mechanism 14 rotates the two raw material products individually to the same set direction. The detection result can determine the orientation of the raw material products. After being rotated to the same direction, the raw material products are conveyed to the second positioning mechanism 13 for precise correction of the raw material product position. The corrected products are then conveyed to the second NG discharge mechanism 12, where NG products are discharged. This mainly handles products with NG appearance. Similarly, if a single nozzle raw material product is NG, the raw material products from both nozzles will be discharged together. Then, the products are conveyed to the first carrier platform 75 and the second carrier platform 85. The vacuum breaking method places two raw material products into corresponding troughs on the carrier. The raw material products are then adsorbed by an attachment below the carrier. The second drive motor 7 and the third drive motor 8 then move the first carrier platform 75 and the second carrier platform 85, awaiting the arrival of the next batch of raw material products. Once the carrier troughs are full, the first drive motor 2 moves the carrier to the dual-nozzle feed head 93, waiting for the nozzles to pick up the materials. After the raw materials are picked up from the carrier, the product position and whether the nozzles are empty are photographed by a flying scan mechanism. Up to 64 raw material products can be photographed simultaneously. After the photographing is completed, if the inspection results are satisfactory, the products are moved to the PCB placement calibration platform 20. Above the PCB, the product is placed in the corresponding position on the PCB board, and the process is repeated until the PCB is full of raw material products. Then, the completed PCB board is transported to the next station by a conveyor belt. At the same time, a PCB board without raw material products is transported to the next station to await placement. The pick-and-place nozzle assembly picks up multiple raw materials from the carrier slot and attaches them to the pick-and-place nozzle. Then, the materials are moved to the image correction NG (Not Good) feeder platform. First, the positions of multiple raw materials are precisely corrected simultaneously. Then, the appearance, position, and empty material checks of the raw materials are performed. The materials that fail the checks are discharged at the NG feeder. The OK raw materials are moved to the PCB pick-and-place correction platform, where multiple raw materials are placed onto the PCB simultaneously. The PCB pick-and-place correction platform uses a MARK point camera on the Z-axis of the pick-and-place machine to find the position of the PCB and then corrects the position of the PCB.

[0052] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
