[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Due to the influence of factors such as equipment, materials, and processes during the manufacturing process, the quality of electronic components may vary. In order to ensure the quality and stable performance of the product, it is necessary to sort the electronic components, select the components with good quality, and remove the defective or non-compliant components. At the same time, in order to ensure the matching performance between components, it is necessary to sort the components and select the components with similar or equal parameters to ensure the stability of the overall performance.
[0033] First embodiment
[0034] Reference Figure 1-Figure 6In order to save the time of loading and improve the loading efficiency, a rotary loading mechanism of a sorting machine is provided, which is composed of a base 1 and a support frame 2 installed on the top of the base 1, a loading component 3 for placing electronic components on a processing station is arranged on the top of the support frame 2, a positioning component 4 for limiting the position of the electronic components is arranged at the bottom of the support frame 2, and a detection component 5 for testing the overflow of glue on the bottom of the electronic components is also arranged on the support frame 2.
[0035] The feeding component 3 includes a support seat 31 fixedly arranged at the top of the support frame 2, and a rotating disk 32 arranged at the bottom of the support seat 31, a connecting seat 33 is arranged at the bottom of the rotating disk 32, a rotating column 34 fixed to the bottom of the rotating disk 32 is rotatably arranged on the inner side of the connecting seat 33, and a bearing fixed to the inner side of the connecting seat 33 is rotatably arranged on the rotating column 34, a servo motor 35 is fixedly installed on the top of the support seat 31, and the bottom end of the output shaft of the servo motor 35 passes through the support seat 31 and is fixedly connected to the rotating disk 32, and a servo motor 35 is fixedly installed on one side of the top of the support frame 2. There is a lifting component 36 for driving the connecting seat 33 to move in the vertical direction. The feeding component 3 also includes a suction component 37 arranged at the bottom of the rotating column 34 for adsorbing electronic components to drive its movement. The output shaft of the servo motor 35 drives the rotating disk 32 to rotate, and the rotating disk drives the rotating column 34 to rotate inside the connecting seat 33. The rotating column 34 drives the suction component 37 at its bottom to rotate, thereby driving the adsorbed electronic components to change positions. At the same time, the lifting component 36 drives the electronic components to move in the vertical direction, so as to adjust the electronic components to different heights.
[0036] The loading component 3 can drive the electronic component to rotate while adjusting its height, grab the electronic component through the suction component 37, and adjust the position of the electronic component through the cooperation of the lifting component 36 and the servo motor 35, so that the way of changing the position of the electronic component is faster and more convenient.
[0037] Since the sizes of different electronic components are different, the height of the electronic components during loading is adjusted by the lifting component 36, which can be suitable for electronic components of different sizes and make loading faster. Specifically, it includes a movable vertical plate 361 detachably installed on one side of the connecting seat 33, and a limiting seat 362 slidably set on the side of the movable vertical plate 361 away from the connecting seat 33 and fixed to the support frame 2. A limiting groove is provided on the top side of the movable vertical plate 361, and a limiting pressure block 364 fixed to the limiting seat 362 is provided at the inner bottom of the limiting groove. A rotating pressure column 363 is provided at one end of the top of the limiting pressure block 364. A stepper motor 365 is fixedly installed on one side of the top of the support frame 2, and the output shaft of the stepper motor 365 passes through the support frame 2 and the limiting seat 362 to be fixed with a rotating block 366, and one end of the rotating block 366 is fixedly connected to the rotating pressure column 363. Limit springs fixed to the top and the limiting seat 362 are respectively fixed on both sides of the movable vertical plate 361.
[0038] In order to grasp the electronic components that need to be loaded more stably, the electronic components are grasped stably by the suction component 37, so that the loading is safer. Specifically, it includes a support plate 371 fixedly set at the bottom of the rotating column 34, and a movable disk 372 set at the top of the support plate 371 and slidably connected to the rotating column 34. A spring 1 is fixed to the bottom of the movable disk 372 and is sleeved on the bottom of the rotating column 34. Six grabbing nozzles 373 distributed in a circular array are set at the bottom of the support plate 371. A connecting tube 374 is detachably installed on the top of the grabbing nozzle 373, and the connecting tube 374 extends through the support plate 371 to the movable disk 372. A spring 2 fixed to the top and the support plate 371 is sleeved on the outer side of the bottom of the connecting tube 374. Spring 1 and spring 2 help to provide a buffering effect when sucking electronic components, thereby improving the safety of grabbing electronic components.
[0039] The movable disk 372 is externally connected to a vacuum pump for connecting to the connecting pipe 374. The vacuum pump forms a negative pressure inside the grabbing nozzle 373. When the grabbing nozzle 373 contacts the surface of the electronic component, a seal is formed between the grabbing nozzle 373 and the electronic component due to the negative pressure, so that the electronic component can be firmly adsorbed on the grabbing nozzle 373. The grabbing nozzle 373 can maintain sufficient adsorption force without causing damage to the electronic component.
[0040] The support frame 2 is arranged at one end of the electronic component conveyor, and the suction component 37 is located at the loading end of one end of the conveyor. The stepper motor 365 is started, and the output shaft of the stepper motor 365 drives the rotating block 366 to rotate. The rotating block 366 drives the rotating pressure column 363 at one end thereof to rotate around the output shaft. The rotating pressure column 363 squeezes the movable vertical plate 361 to move downward through the limiting pressure block 364. The movable vertical plate 361 drives the connecting seat 33 to move downward. The connecting seat 33 pushes the movable disk 372 to move downward on the outside of the rotating column 34. The movable disk 372 pushes the connecting tube 374 and the grabbing nozzle 373 to move downward. The grabbing nozzle 373 moves to the top of the loading end of one end of the conveyor.
[0041] Six grabbing nozzles 373 are provided to load electronic components. The six grabbing nozzles 373 rotate in sequence to hold the electronic components. At the same time, the servo motor 35 is started. The output shaft of the servo motor 35 drives the rotating column 34 to rotate through the rotating disk 32. The rotating column 34 drives the six grabbing nozzles 373 to start rotating through the support plate 371. In this way, the electronic components are loaded one by one in a rotational manner. At the same time, the electronic components pass through the top of the detection component 5, and the bottom of the electronic components is detected. Then the electronic components are transported to the positioning component 4 to enter the next step, which is beneficial to improve the loading accuracy.
[0042] Second embodiment
[0043] Reference Figure 5 In order to ensure that the electronic components can be accurately placed in the required positions during the loading process, the positioning component 4 includes a support platform 41 detachably mounted on the bottom of the support frame 2, and a limiting vertical plate 42 fixedly arranged on one side of the top of the support platform 41, a limiting horizontal rail 43 is fixed on one side of the top of the limiting vertical plate 42, and sliding clamps 47 are respectively arranged at both ends of the support platform 41, and the two sliding clamps 47 are respectively slidably connected to the two ends of the limiting slide rails, and limiting circular blocks 44 are respectively fixed at the bottom of the two sliding clamps 47, and a cam 45 is arranged between the two limiting circular blocks 44, and a stepper motor 2 46 is fixed at the bottom of the support frame 2, and the output shaft of the stepper motor 2 46 passes through the support platform 41 and is fixedly connected to the cam 45, and limiting clamps for clamping and positioning electronic components are respectively fixed on the tops of the two sliding clamps 47, and a reset spring is fixed on one side of the two sliding clamps 47.
[0044] By starting the second stepper motor 46, the output shaft of the second stepper motor 46 drives the cam 45 to rotate, and the cam 45 pushes the two limit round blocks 44 to move to both sides, so that the two sliding clamps 47 are opened, thereby pulling the two ends of the reset spring at the same time, and the reset spring produces elastic deformation and is stretched, and then the electronic component is synchronously moved to between the two limit clamps through the suction component 37, and then after the cam 45 rotates a certain angle, the lack of tight contact with the two limit round blocks 44 makes the reset spring restore its elastic deformation, and pushes the two sliding clamps 47 to move toward the middle at the same time at both ends of the limit rail 43, respectively driving the two limit clamps to move toward the middle, thereby clamping and fixing the electronic component, and proceeding to the next step.
[0045] Stepper motor 1 365 and stepper motor 2 46 are both configured as closed-loop stepper motors. A closed-loop stepper motor is capable of effectively controlling the movement of the motor by adding a position sensor and a tachometer or a Hall sensor and a closed-loop controller to the motor shaft, and achieving high-precision position and speed control through position feedback and speed feedback, thereby improving the control accuracy and stability of the entire system.
[0046] Third embodiment
[0047] Reference Figure 3 In order to detect the overflow of glue at the bottom of the electronic components and improve the qualified rate of the products, the detection component 5 includes a detection table 51 arranged on one side of the top of the support table 41. The detection table 51 can detect the overflow of glue at the bottom of the electronic components. The detection table 51 belongs to the prior art and is common knowledge known to people in this field. It is not disclosed in detail in this application. A connecting plate 52 is provided on one side of the detection table 51 and is fixedly connected to the support frame 2 by bolts. The connecting plate 52 is used to fix the detection table 51 on the support frame 2, and the position of the detection table 51 can be adjusted according to actual detection requirements, so as to adapt to electronic components in different positions.
[0048] The control method of the present invention is automatic control through a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and circuit connection in detail.
[0049] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
