Description

Technical Field

[0001] This utility model relates to the field of production line technology, and in particular to an SMT production line. Background Technology

[0002] SMT refers to surface mount technology. Compared with traditional through-hole mounting technology, it has advantages such as small footprint, high speed, high efficiency and low cost, and is widely used in the field of electronic manufacturing.

[0003] For example, patent (CN218514598U) discloses a novel SMT mobile phone production line assembly equipment, including a support frame. Two sets of support frames are included. The bottom of an iron plate is fixedly mounted on the top of a magnet. Two sets of sliding grooves and a first pressure plate are fixedly mounted on the top of the iron plate. A second pressure plate is slidably mounted on the two sets of sliding grooves. The first and second pressure plates clamp and stabilize the SMT mobile phone, preventing slippage when the mounting head is applying the SMT phone screen. This ensures not only the accuracy of the applied components but also prevents any impact on the overall quality of the final product.

[0004] When using the above technology, the following technical problems were found in the existing technology: Currently, the conveyor track of production equipment is usually fixed, which means that it can only convey workpieces of a certain width. For workpieces whose width does not match the conveyor track, adjustment is required by a straightening mechanism, which affects the conveying efficiency of the workpieces. To address this, we designed an SMT production line to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An SMT production line includes a pick and place machine. Both ends of the pick and place machine are slidably connected to U-shaped clamps. Several conveyor rollers are rotatably connected to the ends of the two U-shaped clamps that are close to each other. A conveyor belt is rotatably connected to the outer sides of the conveyor rollers. A width adjustment mechanism for moving the two U-shaped clamps is provided inside the pick and place machine. A U-shaped frame is fixed to one side of the top of the pick and place machine, and a pick and place device is mounted on the inner side of the U-shaped frame.

[0007] As a preferred embodiment of the SMT production line provided by this utility model, the adjustment mechanism includes a slide, a transmission disk, a worm gear, a worm, and a servo motor. The transmission disk is rotatably connected to the inside of the pick and place machine. Arc grooves are provided at both ends of the transmission disk. A slide is slidably connected to the inside of the arc groove. The end of the slide away from the transmission disk is fixed to a U-shaped clamp. The inside of the slide is slidably connected to the pick and place machine.

[0008] In a preferred embodiment of the SMT production line provided by this utility model, a servo motor is mounted on the inner side of the pick-and-place machine. A worm gear is fixed to the output end of the servo motor. One side of the worm gear is rotatably connected to the pick-and-place machine. A worm wheel is meshed with the outer side of the worm gear. The bottom end of the worm wheel is rotatably connected to the pick-and-place machine. The top end of the worm wheel is fixedly connected to the transmission disk.

[0009] In a preferred embodiment of the SMT production line provided by this utility model, guide blocks are fixed on both sides of the top of the pick-and-place machine, and the two ends of the guide blocks are slidably connected to the U-shaped clamps.

[0010] In a preferred embodiment of the SMT production line provided by this utility model, a fixing block is fixed on one side of the top of the pick-and-place machine, a limiting sliding rod is rotatably connected to the inner side of the fixing block, the two ends of the limiting sliding rod are respectively slidably connected to one of the conveying rollers, a driven bevel gear is fixed on the outer side of the limiting sliding rod, a main bevel gear is meshed with the bottom end of the driven bevel gear, and a second servo motor is mounted on one side of the top of the pick-and-place machine, the output end of the second servo motor is fixed to the main bevel gear.

[0011] In a preferred embodiment of the SMT production line provided by this utility model, limit strips are fixed at both ends of the outer side of the limiting sliding rod.

[0012] In a preferred embodiment of the SMT production line provided by this utility model, a template frame is slidably connected to the top of the U-shaped frame, the bottom of the template frame is fixed to the placement device, and an electric push rod is assembled at the top of the inner side of the U-shaped frame, with the output end of the electric push rod fixed to the template frame.

[0013] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0014] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0015] This utility model provides an SMT production line. The workpiece is placed between two U-shaped clamps on a conveyor belt. A servo motor drives a worm gear to rotate, which in turn drives a worm wheel and a transmission disc to rotate synchronously. The transmission disc, in turn, adjusts the two slides, U-shaped clamps, conveyor rollers, and conveyor belt according to the workpiece width for effective width limiting. A pick-and-place machine then places the workpiece, thus improving the accuracy and stability of the placement process.

[0016] By starting the second servo motor, the limiting sliding rod is driven to rotate synchronously with the bevel gear and the conveyor belt, which facilitates the transport of the workpiece to the placer for placement. Furthermore, the first servo motor drives the two U-shaped clamps, the conveyor belt, and the conveyor rollers to adjust according to the width of the workpiece. While the limiting sliding rod effectively drives the conveyor belt to rotate, the conveyor rollers and the conveyor belt on both sides can slide against each other, so as to adjust the width of the workpiece during transport.

[0028] Please refer to Figures 1-5 An SMT production line includes a pick and place machine 1. Both ends of the inner side of the pick and place machine 1 are slidably connected to U-shaped clamps 6. Several conveyor rollers 8 are rotatably connected to the ends of the two U-shaped clamps 6 that are close to each other. A conveyor belt 7 is rotatably connected to the outer sides of the several conveyor rollers 8. A width adjustment mechanism for moving the two U-shaped clamps 6 is provided inside the pick and place machine 1. A U-shaped frame 2 is fixed to one side of the top of the pick and place machine 1. A pick and place device 5 is assembled inside the U-shaped frame 2. The adjustment mechanism includes a slide 10, a transmission disk 11, a worm gear 13, a worm 14, and a servo motor 15. The transmission disk 11 is rotatably connected inside the pick and place machine 1. Arc-shaped grooves 12 are opened at both ends inside the transmission disk 11. A slide 10 is slidably connected to the inner side of the arc-shaped grooves 12. The end of the slide 10 away from the transmission disk 11 is fixed to the U-shaped clamps 6. The inner side of the slide 10 is slidably connected to the pick and place machine 1.

[0029] The inner side of the pick and place machine 1 is equipped with a servo motor 15. The output end of the servo motor 15 is fixed with a worm gear 14. One side of the worm gear 14 is rotatably connected to the pick and place machine 1. The outer side of the worm gear 14 is meshed with a worm wheel 13. The bottom end of the worm wheel 13 is rotatably connected to the pick and place machine 1. The top end of the worm wheel 13 is fixedly connected to the transmission disk 11.

[0030] In use, the workpiece is placed between two U-shaped clamps 6 and on the conveyor belt 7. Then, the servo motor 15 is started to drive the worm gear 14 to rotate. The worm gear 14 drives the worm wheel 13 and the transmission disk 11 to rotate synchronously. The transmission disk 11 drives the two slides 10, U-shaped clamps 6, conveyor rollers 8 and conveyor belt 7 to adjust according to the width of the workpiece, so as to effectively limit the width of the workpiece. Then, the patcher 5 is used to patch the workpiece, thereby promoting the accuracy and stability of patching.

[0031] Guide blocks 9 are fixed on both sides of the top of the pick and place machine 1. The two ends of the guide blocks 9 are slidably connected to the U-shaped clamps 6 respectively. The guide blocks 9 effectively improve the sliding stability of the two U-shaped clamps 6, so as to effectively adjust according to the width of the workpiece.

[0032] A fixing block 20 is fixed on one side of the top of the pick and place machine 1. A limiting sliding rod 19 is rotatably connected to the inner side of the fixing block 20.

[0033] Specifically, by starting the servo motor 16, the main bevel gear 17 and the driven bevel gear 18 are rotated. The driven bevel gear 18 drives the limiting sliding rod 19 to rotate synchronously, so that the limiting sliding rod 19 drives one of the conveyor rollers 8 on both sides to rotate. One of the conveyor rollers 8 drives the conveyor belt 7 to move, so that the conveyor belt 7 can effectively transport the workpieces to the placer 5 directly below for placement.

[0034] Limiting strips are fixed at both ends of the outer side of the limiting sliding rod 19. The limiting sliding rod 19 slides with one of the conveying rollers 8, effectively starting the servo motor 16 to drive the limiting sliding rod 19, the bevel gear 18 and the conveyor belt 7 to rotate synchronously, which facilitates the delivery of the workpiece to the placer 5 for placement. In addition, the servo motor 15 drives the two U-shaped clamps 6, the conveyor belt 7 and the conveyor rollers 8 to adjust according to the width of the workpiece. While the limiting sliding rod 19 effectively drives the conveyor belt 7 to rotate, the conveyor rollers 8 and the conveyor belt 7 on both sides can slide against each other to adjust the width of the workpiece during delivery.
