[0031] Such as Figure 1 AndFigure 2 As shown in the figure, a circuit board IC plug-in machine includes a workbench 1, at least one set of IC feeding mechanisms 2, a circuit board feeding mechanism 3, an XY-axis motion module 4, a multi-axis IC mechanical claw mechanism 5, a camera 6, and an IC mechanical claw library 7. The IC feeding mechanism 2 is installed at one end of the workbench 1. The XY-axis motion module 4 is installed on the workbench 1. The multi-axis IC mechanical claw mechanism 5 is installed on the XY-axis motion module 4. The circuit board feeding mechanism 3 is installed on the workbench 1 and is disposed opposite to the multi-axis IC mechanical claw mechanism 5 in the vertical direction. The camera 6 is installed on the workbench 1 and is located between the IC feeding mechanism 2 and the circuit board feeding mechanism 3. The IC mechanical claw library 7 is installed on the workbench 1 and is located at one end of the camera 6, and is used to place multiple IC mechanical claws of different specifications.

[0032] As Figure 5 shown in the figure, the IC feeding mechanism 2 can be set to one set or two sets. If it is set to two sets, the feeding of electronic components can be carried out separately, and the feeding efficiency is higher. The XY-axis motion module 4 includes two sets of Y-axis motion units 41 and one set of X-axis motion unit 42. The two sets of Y-axis motion units 41 are installed on the workbench 1, and both ends of the X-axis motion unit 42 are installed on the two sets of Y-axis motion units 41. The two sets of Y-axis motion units 41 and the X-axis motion unit 42 can drive the multi-axis IC mechanical claw mechanism 5 to move in the X-axis and Y-axis directions. The camera 6 can take pictures of the position and angle of the electronic component clamped by the multi-axis IC mechanical claw mechanism 5 at that time and send them to the multi-axis IC mechanical claw mechanism 5, and the multi-axis IC mechanical claw mechanism 5 adjusts the angle required for plugging; the IC mechanical claw library 7 stores multiple mechanical claws of different specifications and types, which is convenient for quick replacement when clamping different types of electronic components.

[0033] The feeding of electronic components is completed through the IC feeding mechanism 2, and the feeding of the circuit board is completed through the circuit board feeding mechanism 3. The XY-axis motion module 4 drives the multi-axis IC mechanical claw mechanism 5 to move along the X-axis and Y-axis directions, so that the multi-axis IC mechanical claw mechanism 5 grabs the electronic components to be plugged on the IC feeding mechanism 2. After the grabbing is completed, the camera 6 takes pictures of the electronic components on the multi-axis IC mechanical claw mechanism 5 and sends them to the multi-axis IC mechanical claw mechanism 5. The control module of the multi-axis IC mechanical claw mechanism 5 compares the position and angle of the electronic component with the angle and direction required for plugging, and controls the multi-axis IC mechanical claw mechanism 5 to adjust the position and angle to meet the plugging requirements of the electronic component. The XY-axis motion module 4 drives the multi-axis IC mechanical claw mechanism 5 to move along the X-axis and Y-axis directions to a preset position, and inserts the electronic component into the circuit board.

[0034] In this way, the circuit board IC plug-in machine, through the cooperation of the IC feeding mechanism 2, the circuit board feeding mechanism 3, the XY-axis movement module 4, the multi-axis IC mechanical claw mechanism 5, the camera 6, and the IC mechanical claw library 7, completes the feeding of electronic components through the IC feeding mechanism 2, completes the feeding of the circuit board through the circuit board feeding mechanism 3. The multi-axis IC mechanical claw mechanism 5 grabs the electronic components to be inserted in the IC feeding mechanism 2 through the control of the XY-axis movement module 4. After the camera 6 takes pictures of the electronic components grabbed by the IC feeding mechanism 2, it sends them to the multi-axis IC mechanical claw mechanism 5. The control module on the multi-axis IC mechanical claw mechanism 5 adjusts the insertion angle and position of the electronic components according to the angle and position of the electronic components and in combination with the insertion position and angle of the corresponding electronic components on the circuit board, ensuring that the electronic components can be accurately inserted on the circuit board, realizing the rapid insertion of electronic components and the circuit board, improving work efficiency and saving labor costs.

[0035] As Figure 3 shown, in one of the embodiments, the IC feeding mechanism 2 includes a mounting base 21, an IC feeding groove 22, a linear vibrator 23, two IC packaging tube feeding cylinders 24, an IC packaging tube placement assembly 25, an IC pushing assembly 26, and an IC packaging tube feeding groove 27. The IC feeding groove 22 is installed on the mounting base 21 and is at the output end of the electronic components. The linear vibrator 23 is installed at the bottom of the IC feeding groove 22. The IC pushing assembly 26 is installed on the mounting base 21 and is at the input end of the electronic components. The IC packaging tube placement assembly 25 is installed on the mounting base 21 and is between the IC feeding groove 22 and the IC pushing assembly 26. The IC packaging tubes 28 are sequentially placed vertically in the IC packaging tube placement assembly 25, and several electronic components are sequentially placed in the IC packaging tubes 28. The two IC packaging tube feeding cylinders 24 are symmetrically arranged on the mounting base 21 and are at the bottom of the lowermost IC packaging tube 28, for supporting both ends of the IC packaging tube 28. The IC packaging tube feeding groove 27 is installed on the mounting base 21 and is at the bottom of the lowermost IC packaging tube 28. The IC feeding mechanism 2 includes two support cylinders 29, and the two support cylinders 29 are respectively fixedly installed on the two support plates 2511 for supporting the second-lowermost IC packaging tube 28.

[0036] In this way, several IC packaging tubes 28 are stacked in the IC packaging tube placement assembly 25 in sequence. Electronic components are placed in the IC packaging tubes 28 in sequence. The two ends of the bottommost IC packaging tube 28 are supported by two IC packaging tube blanking air cylinders 24. Two support air cylinders 29 support the two ends of the second bottommost IC packaging tube 28. The IC packaging tubes 28 above the second bottommost IC packaging tube 28 are stacked on the second bottommost IC packaging tube 28 in sequence. The IC pushing assembly 26 is started. The IC pushing assembly 26 is adapted to the position of the bottommost IC packaging tube 28. The IC packaging tube 28 is communicated with the IC loading chute 22. The electronic components in the bottommost IC packaging tube 28 are pushed into the IC loading chute 22 by the IC pushing assembly 26. The linear vibrator 23 is started to move the electronic components in the IC loading chute 22 towards the circuit board loading mechanism 3. When there are no electronic components in the bottommost IC packaging tube 28, the two IC packaging tube blanking air cylinders 24 retract, causing the bottommost IC packaging tube 28 to fall into the IC packaging tube blanking chute 27. At this time, the two IC packaging tube blanking air cylinders 24 extend, and the two support air cylinders 29 retract, causing the other IC packaging tubes 28 to fall and be supported by the two IC packaging tube blanking air cylinders 24. At this time, the two support air cylinders 29 extend to support the second bottommost IC packaging tube 28. Continuing to load the electronic components in the above manner can quickly complete the loading work of the electronic components.

[0037] In one embodiment, the IC packaging tube placement assembly 25 includes two groups of support units 251. The two groups of support units 251 are symmetrically arranged on the mounting base 21 respectively. The distance between the two groups of support units 251 is adapted to the length of the IC packaging tube 28.

[0038] The support unit 251 includes a support plate 2511, a fixing plate 2512, an adjusting plate 2513, an adjusting member 2514, a positioning member 2515, a limiting member 2516, and a spring 2517. The support plate 2511 is installed on the mounting base 21. The fixing plate 2512 is installed on the other side of the support plate 2511 and is arranged parallel to the fixing plate 2512, so that a receiving groove 2518 is formed between the fixing plate 2512 and the support plate 2511. The end of the IC packaging tube 28 is received in the receiving groove 2518. The adjusting member 2514 is rotatably arranged at the middle position of the adjusting plate 2513 and is used to control the adjusting plate 2513 to move closer to or away from the fixing plate 2512 on the support plate 2511. The positioning member 2515 is detachably installed on the adjusting plate 2513 and is used to fix the adjusting plate 2513 on the support plate 2511 so that it cannot move. A notch 25131 is formed on the adjusting plate 2513. The limiting member 2516 is installed on the support plate 2511 and is received in the notch 25131. One end of the spring 2517 is installed on the limiting member 2516, and the other end is installed on the adjusting plate 2513. The height of the notch 25131 is adapted to the height of the limiting member 2516.

[0039] In this way, the width of the support unit 251 can be adjusted according to the width of the IC packaging tube 28. When it is necessary to adjust the width of the support unit 251, the positioning member 2515 is detached from the adjusting plate 2513, so that the adjusting plate 2513 can move on the support plate 2511. The adjusting member 2514 is rotated clockwise or counterclockwise, so that the adjusting member 2514 drives the adjusting plate 2513 to move to a preset position on the support plate 2511. The adjusting plate 2513 is provided with scales, and the moving distance can be judged according to the scales. The positioning member 2515 passes through the positioning hole of the adjusting plate 2513 and abuts against the support plate 2511, and the width adjustment of the support unit 251 is completed, so that the support unit 251 can be adapted to IC packaging tubes 28 of different widths.

[0040] Such as Figure 4As shown, in one of the embodiments, the IC pushing component 26 includes a mounting bracket 261, a first motor 262, a first driving pulley 263, a first driven pulley 264, a first synchronous belt 265, a tension pulley 266, a roller mounting seat 267, a roller 268, and a coil spring 269. The mounting bracket 261 is fixedly installed on the mounting seat 21. The first motor 262 is fixedly installed on the mounting bracket 261. The first driving pulley 263 is installed on the first motor 262. The first driven pulley 264 is rotatably installed on the mounting bracket 261. Both ends of the first synchronous belt 265 are sleeved on the first driving pulley 263 and the first driven pulley 264 respectively. The tension pulley 266 is rotatably installed on the mounting bracket 261 and abuts against the first synchronous belt 265. The coil spring 269 is installed on the mounting seat 21 and its output end is inserted into the IC packaging tube 28. The roller mounting seat 267 is installed on the mounting seat 21. The roller 268 is rotatably installed on the roller mounting seat 267 and one end thereof is connected to the first driven pulley 264. The roller 268 abuts against the coil spring 269, and when the roller 268 rotates, it drives the coil spring 269 to move.

[0041] In this way, when it is necessary to push the electronic components in the IC packaging tube 28, the first motor 262 is started. The first motor 262 drives the first driving pulley 263 to rotate. The first driving pulley 263 drives the first driven pulley 264 to rotate through the first synchronous belt 265. The first driven pulley 264 drives the roller 268 to rotate. Since the roller 268 abuts against the coil spring 269, when the roller 268 rotates, it drives the coil spring 269 to move into the IC packaging tube 28, thereby pushing the electronic components in the IC packaging tube 28 towards the circuit board feeding mechanism 3 until all the electronic components are pushed out of the IC packaging tube 28. Then the first motor 262 stops rotating, and the rotational force of the coil spring 269 itself retracts to the initial position, quickly completing the pushing of the electronic components.

[0042] Such as Figure 6As shown, in one embodiment, the circuit board loading mechanism 3 includes a fixed bracket 31, a second motor 32, a second driving wheel 33, a second driven wheel 34, a second synchronous belt 35, a rotating shaft 36, two first conveyor wheels 37, several second conveyor wheels 38, and a conveyor belt 39.

One end of the rotating shaft 36 is installed on the second driven wheel 34, and the other end passes through the two first conveyor wheels 37. The conveyor belt 39 is sleeved on the two first conveyor wheels 37 and several second conveyor wheels 38 respectively.

[0043] In this way, place the circuit board on the conveyor belt 39, start the second motor 32. The second motor 32 drives the second driving wheel 33 to rotate. The second driving wheel 33 drives the second driven wheel 34 to rotate through the second synchronous belt 35. The second driven wheel 34 drives the rotating shaft 36 to rotate. The rotating shaft 36 drives the two first conveyor wheels 37 to rotate synchronously. The two first conveyor wheels 37 drive several second conveyor wheels 38 to rotate through the conveyor belt 39, thereby controlling the circuit board on the conveyor belt 39 to move to a preset position.

The tracheal joint 532 is installed on the top of the ball spline shaft 533. The jaw cylinder 536 is installed on the bottom of the ball spline shaft 533. The ball spline shaft 533 is of a hollow structure and is communicated with the tracheal joint 532;

[0049] The ball spline shaft 533 can serve as the rotating shaft of the rotating synchronous pulley 5222.

When the rotating synchronous pulley 5222 rotates, the ball spline shaft 533 can be driven to rotate together by the ball spline shaft sleeve 534, and the ball spline shaft 533 can also slide axially within the ball spline shaft sleeve 534.

[0050] When it is necessary to pick up electronic components, start the lifting servo motor 5211. The lifting servo motor 5211 drives the lifting driving pulley 5212 to rotate. The lifting driving pulley 5212 drives the lifting synchronous belt 5214 to rotate. The lifting synchronous belt 5214 then drives the lifting driven pulley 5213 to rotate. During the movement of the lifting synchronous belt 5214, it drives the spline shaft fixing seat 535 to move on the slide rail 5215 through the slider 5216, and then drives the ball spline shaft 533 to move towards the electronic components in the rotating synchronous pulley 5222 to a preset position, and the lifting servo motor 5211 stops. Start the rotating servo motor 5221. The rotating servo motor 5221 rotates and then drives the rotating synchronous belt 5223 to rotate. The rotating synchronous belt 5223 drives the rotating synchronous pulley 5222 to rotate, and then drives the ball spline shaft 533 to rotate to a preset angle through the ball spline shaft sleeve 534, facilitating the jaw cylinder 536 to pick up the electronic components. At this time, start the jaw solenoid valve 531. The air pipe joint 532 is connected to the external air source, and the gas enters the jaw cylinder 536 through the ball spline shaft 533 to control the jaw cylinder 536 to pick up the electronic components. The multi-axis IC mechanical claw mechanism 5 can simultaneously pick up electronic components at multiple different heights and angles and insert the electronic components into the corresponding positions on the circuit board.

[0051] The limiting unit 537 includes an induction sheet 5371 and a groove type photoelectric switch 5372. The groove type photoelectric switch 5372 is installed on the installation base 51. The induction sheet 5371 is installed on the slider 5216 and one end is fixedly connected to the lifting synchronous belt 5214. The induction sheet 5371 is detachably connected to the spline shaft fixing seat 535, and the induction sheet 5371 and the spline shaft fixing seat 535 can move synchronously axially.

[0052] In this way, through the setting of the limit unit 537, when the groove-type photoelectric switch 5372 detects the induction piece 5371, it sends a control signal to the control module of the lifting servo motor 5211, and the control module controls the lifting servo motor 5211 to stop, preventing the ball spline shaft 533 from continuing to move upward and colliding with other components of the device, causing damage.

[0053] Furthermore, a plurality of notches 5331 are formed in the ball spline shaft 533 along the axial direction.

[0054] In this way, through the setting of the plurality of notches 5331, a plurality of tiny gaps can be formed between the ball spline shaft 533 and the ball spline bushing 534, facilitating the axial movement of the ball spline shaft 533 and preventing the ball spline bushing 534 from completely fastening the ball spline shaft 533.

[0055] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
