Abstract
Description
Technical Field
[0001] This application relates to the field of robotic suction equipment technology, and more specifically, to a suction device and suction equipment. Background Technology
[0002] In the current 3C electronics manufacturing industry, some electronic component manufacturing processes require the handling and positioning of components. While meeting production needs, the operation, safety, stability, and cost of the equipment must also be comprehensively considered. Existing robotic handling equipment typically uses six-axis or nine-axis robotic arms paired with negative pressure suction nozzles for handling. However, multi-axis robotic arms are expensive, and the number of negative pressure suction nozzles on a single arm is limited, with uniform movements, making it difficult to adapt to the flexibility of picking up different components. For example, Chinese patent CN202022787508.4 discloses an automated handling device that uses a six-axis robotic arm and suction cup-type fingers, with one robotic arm moving to control one suction cup-type finger. Therefore, its structure is too large, costly, and unable to handle the need to pick up single or multiple workpieces. Utility Model Content

[0034] Figures 1 to 5 An embodiment of the suction device of this application is illustrated schematically.
[0035] like Figures 1 to 5 As shown, this application discloses a suction device, which includes: a mounting plate assembly 1; a drive assembly 2, disposed on the mounting plate assembly 1, including a drive motor 21; multiple drive motors 21 arranged in parallel, with their motor shafts arranged in parallel; a rotation assembly 3, disposed on the drive assembly 2, including multiple rotating arms 31; the middle part of each rotating arm 31 is connected to the motor shaft of each drive motor 21; and multiple suction assemblies 4, each suction assembly 4 arranged in pairs below the two arm ends of the rotating arms 31, including corresponding suction mechanisms and reset mechanisms. The suction mechanism is slidably disposed relative to the mounting plate assembly 1 and is squeezed and lowered by the rotation of the rotating arms 31. The suction mechanism includes an axial rotation motor 41, the motor shaft of which is connected to a negative pressure suction head 42. The reset mechanism is connected to the suction mechanism and the mounting plate assembly 1, and pulls and resets the suction mechanism.
[0036] Through the above structural design, the embodiment of this application uses a drive motor 21 to rotate the rotating arm 31 to press down the suction mechanism. Each rotating arm 31 can control two sets of suction mechanisms in different positions, and multiple drive motors 21 work simultaneously, thus meeting the suction needs of single or multiple products. The suction mechanism automatically returns to its original position through a reset mechanism, and an axial rotation motor 41 is also provided to meet the position requirements of the suction correction components. It is flexible in use and low in cost, and can inexpensively realize the product manufacturing process in the 3C electronics field.
[0037] In some embodiments of this application, such as Figure 1 and Figure 2As shown, the axial rotation motor 41 is a hollow shaft stepper motor. The suction mechanism also includes an air supply pipe 43. The air supply pipe 43 is connected to the upper end of the motor shaft of the hollow shaft stepper motor. The lower end of the motor shaft of the hollow shaft stepper motor is connected to the negative pressure suction head 42. The hollow shaft stepper motor is a specially designed stepper motor, characterized by a certain cavity or channel in the middle of the motor shaft. This structure gives the hollow shaft stepper motor some unique application advantages, making it better suited for occasions where light, gas, and liquids need to pass through within the axis. In this application, the axial rotation motor 41 uses a hollow shaft stepper motor, and the suction pipe of the negative pressure suction head 42 is realized through the motor shaft of the hollow shaft stepper motor, making the suction mechanism compact and simple, and achieving lightweighting of the device. This greatly reduces the volume and length of the air supply line, avoiding interference with the suction action caused by the excessively long air supply line arrangement in traditional applications. Therefore, the embodiments of this application can achieve product production faster and more accurately, with good stability and higher production efficiency.
[0038] In some embodiments of this application, the suction mechanism further includes a bellows (not shown), which is connected to the upper end of the gas delivery pipe 43. A bellows support 14 is provided on the mounting plate assembly 1, and the bellows support 14 has bellows bundle holes. A bellows is an axially expandable tubular elastic sensitive element; using it to form the gas delivery line of the negative pressure suction head 42 can better accommodate the vertical movement of the suction mechanism and protect gas delivery safety. The bellows support 14 on the mounting plate assembly 1 can constrain and position the bellows through the bellows bundle holes, thereby maintaining pipeline stability, reducing operational interference, and improving the accuracy and safety of the device's operation.
[0039] In some embodiments of this application, such as Figures 1 to 5 As shown, the suction mechanism also includes a base plate 44. The base plate 44 is slidably connected to the mounting plate assembly 1, and an axial rotation motor 41 is mounted on the front of the base plate 44. The top surface of the base plate 44 is a flat structure. Rollers 32 are provided at the arm end of the rotating arm 31, and the rollers 32 roll in contact with the top surface of the base plate 44. The base plate 44 serves as the mounting base for the suction mechanism, with the mounting plate assembly 1 slidably connected to its back, and the axial rotation motor 41 and the negative pressure suction head 42 fixedly mounted on its front, thereby driving the negative pressure suction head 42 to move up and down to achieve suction, handling, and rotational correction. The top surface of the base plate 44 is a smooth plane, contacting the rollers 32 at the arm end of the rotating arm 31. When the rotating arm 31 rotates, the rollers 32 press down on the base plate 44 while rolling, achieving depth control of the suction mechanism. This drive method has a simple structure, low assembly precision requirements, is convenient and accurate to use, and easy to maintain, effectively improving production efficiency and reducing production costs. Moreover, in this embodiment, each rotating arm 31 can achieve the downward pressure control of two sets of parallel suction mechanisms through two rollers 32 at both ends, thus having more suction points, which can match more products and process requirements, and can simultaneously adsorb a single product or multiple products, making it more flexible and convenient to use.
[0040] In some embodiments of this application, such as Figures 1 to 5 As shown, the mounting plate assembly 1 is equipped with a linear slide rail 11, and a slider is mounted on the linear slide rail 11. The base plate 44 is slidably connected to the linear slide rail 11 via the slider. The reset mechanism of the suction assembly 4 is a tension spring 45, which is arranged parallel to the linear slide rail 11. When the rotating arm 31 stops rotating and stops pressing down on the suction mechanism, the tension spring 45 can automatically reset the suction mechanism through its own tension. This method can save energy, meet the assembly needs of general small parts, and thus further reduce production costs.
[0041] In some embodiments of this application, reference is made to Figure 1 As shown, the rotating assembly 3 also includes a blocking block 33. The blocking block 33 is fixedly mounted on the mounting plate assembly 1 and located on the rotation path below the rotating arm 31. The blocking block 33 can limit the rotation of the rotating arm 31, preventing the roller 32 from disengaging from the base plate 44 due to excessive rotation angle of the rotating arm 31, thereby maintaining the operational safety of the device.
[0042] In some embodiments of this application, such as Figure 1 and Figure 4 As shown, the suction device further includes a connecting assembly 5. The connecting assembly 5 is mounted on the mounting plate assembly 1 and includes a connecting plate 51. The connecting plate 51 is provided with a connecting clamping block 52 for connecting the robotic arm. The connecting clamping block 52 is provided with two arc-shaped clamping arms 521, which form a clamping hole and are connected close together by bolts. (Reference) Figure 4 As shown in the enlarged view, the connecting clamping block 52 forms two arc-shaped clamping arms 521 that can approach each other through two vertical cuts. A clamping hole is formed in the middle of the arc-shaped clamping arms 521, which can be connected to the fixed shaft at the end of the robot arm. One end of the two arc-shaped clamping arms 521 is provided with aligned holes, which can be tightened by screwing in bolts to hold the fixed shaft and achieve a reliable connection.
[0043] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the mounting plate assembly 1 has a motor plate 12 with a through hole. The drive motor 21 is fixedly mounted on the motor plate 12, and the motor shaft of the drive motor 21 passes through the through hole to achieve the transition of the motor shaft from the rear to the front of the mounting plate assembly 1. The rotating arm 31 has a mating hole in the middle, and it is fitted onto the motor shaft of the drive motor 21 through the mating hole to achieve rotational drive.
[0044] In some embodiments of this application, such as Figures 1 to 5As shown, the suction device also includes a photoelectric sensor 13. The suction mechanism includes a blocking plate that extends into the detection area of the photoelectric sensor 13, thereby enabling precise detection of the suction mechanism's movement and providing feedback to controllers such as the central control unit for automatic feedback control. Figure 2 As shown, in this embodiment, the photoelectric sensor 13 is arranged in at least two directions to respectively detect the descent depth of the suction mechanism and the rotation angle of the negative pressure suction head 42. One photoelectric sensor 13 is used in conjunction with the first blocking plate 46 (see...). Figure 1 This is used to detect the descent depth of the suction mechanism. Another photoelectric sensor 13 is used in conjunction with the second blocking plate 48 (see...). Figure 2 This allows for the detection of the rotation angle of the negative pressure suction head 42. The first blocking plate 46 is mounted on the base plate 44, and the second blocking plate 48 is mounted on the motor shaft of the axial rotation motor 41. Simultaneously, the corresponding photoelectric sensor 13 is also mounted on the base plate 44 and moves accordingly. (Reference) Figure 3 The photoelectric sensor 13 of this application is provided with a photoelectric switch access point 15 for connecting the electrical signal line, and the axial rotation motor 41 is provided with a rotation switch access point 47 for connecting the electrical signal line.
[0045] According to another aspect of this application, a suction device is provided, comprising: a robotic arm and a suction device as described in the embodiments above. The suction device is mounted below the end effector of the robotic arm for processing electronic components. Because the suction device of this application already possesses suction lifting and rotation adjustment capabilities, its robotic arm can adopt a simpler structure to reduce equipment costs.
[0046] Combination Figures 1 to 5 The working principle of this application is explained as follows:
[0047] First, the suction device of this embodiment is mounted on the robotic arm via the connecting clamp 52 for assembly. After starting work, the drive motor 21 controls the suction mechanism to descend via the rotating arm 31 and rollers 32. The specific descent depth is determined by the control signal and the feedback signal from the photoelectric sensor 13, achieving precise control. Simultaneously, the tension spring 45, acting as a reset mechanism, automatically restores the suction mechanism to its original position after the downward pressure is complete, thus achieving product suction. After product suction, product handling can be performed, such as controlling the movement of the robotic arm on the scaffold structure. Simultaneously, the axial rotation motor 41 can adjust the product position by rotating its motor shaft, helping to correct any misalignment. The rotation correction angle is determined by the control signal and the feedback signal from the photoelectric sensor 13, achieving precise leveling and positioning. Through repeated cyclical movements, the product manufacturing process can be achieved efficiently and quickly. This embodiment of the application features a simple structure, precise control, good stability and maintainability, and low cost.
