[0088] Specifically, there are two feeding modules 10, which have the same structure and are arranged side by side. One of the feeding modules 10 is responsible for loading to form a loading bin 100, and the other feeding module 10 is responsible for unloading to form a unloading bin 200. The subsequent workstation of the feeding module 10 is provided with a robot for cooperating with it to realize loading and unloading; the feeding module 10 includes a fixed plate 102, a first lifting plate 110, a lifting drive mechanism and a sensing module 105. The first lifting plate 110 is used to stack trays 103, each tray 103 is placed with products, and when the products on the tray 103 are grabbed by the robot, an empty tray 103 is formed; the lifting drive mechanism and the sensing module 105 are connected to each other. The first lifting plate 110 is connected to the first lifting plate 110 to drive the first lifting plate 110 to lift relative to the fixed plate 102.

The staff stacks the pallet 103 on the first lifting plate 110 in the upper bin 100. Therefore, the sensing block 116 in the upper bin 100 triggers the sensing unit 109. The sensing unit 109 sends a start signal to the lifting drive mechanism in the upper bin 100, so that the lifting drive mechanism drives the first lifting plate 110 to drive the pallet 103 to rise a certain distance. After the sensing module 105 senses the pallet 103, the machinery of the subsequent workstation The robot grabs the products on the tray 103 by hand. When the robot takes away all the products on the tray 103, the robot grabs the empty tray 103 and puts it into the lower bin 200. After the sensing module 105 senses the empty tray 103, the lifting drive mechanism drives the first lifting plate 110 to drive the empty tray 103 to descend a certain distance, and repeats the above steps until the loading is completed. At this time, the first lifting plate 110 in the upper bin 100 is at the highest value, and the first lifting plate 110 in the lower bin 200 is stacked to the maximum value because the empty trays 103 have been stacked. The sensing block 116 in the lower bin 200 triggers the sensing unit 109, and the sensing unit 109 sends a stop signal to the lifting drive mechanism in the lower bin 200, and the empty tray 103 is manually taken away, and the tray 103 is stacked on the first lifting plate 110 in the upper bin 100 again, thereby saving manpower for frequent loading and unloading of materials and greatly improving the efficiency of loading and unloading;

[0090] The fixed plate 102 is provided with an empty slot in the middle to form a material trough 101 for loading or unloading the tray 103. The fixed plate 102 is provided with a group of positioning components 111 which are symmetrically distributed on the left and right sides to perform preliminary positioning on the tray 103. The positioning components 111 include a stopper rod 107 and four positioning rods 112. The left and right sides of the mechanism installation box 117 are provided with mounting plates 113 fixedly connected thereto.

[0100] The present invention provides an automated flipping and moving device 15, comprising a second lifting plate 151, a lifting drive mechanism, a product adsorption plate 152 and a flipping mechanism, wherein the flipping mechanism is installed on the second lifting plate 151, the lifting drive mechanism is connected to the second lifting plate 151 to drive the second lifting plate 151 and the flipping mechanism to lift, and the flipping mechanism is connected to the product adsorption plate 152 to drive the product adsorption plate 152 to flip;

[0101] The lifting drive mechanism is a motor eccentric structure, which includes a driving member 157, a rotating arm 158 and a cam 159. The cam 159 is mounted on one end of the rotating arm 158, and the cam 159 is arranged inside the movable groove 156 and is slidably connected thereto. The driving member 157 is mounted on the back of the fixed seat 153. The driving member 157 drives the rotating arm 158 to rotate, and enables the cam 159 to drive the second lifting plate 151 to move. The fixed seat 153 is also included. The front end surface of the fixed seat 153 is equipped with two lifting guide rails 154. The back of the second lifting plate 151 is equipped with a lifting slider 155 slidably connected to the lifting guide rail 154. The second lifting plate 151 is provided with an oblong movable groove 156, and also includes a sensing unit 1510 for detecting the height position of the second lifting plate 151 and communicating with the lifting drive mechanism, wherein the sensing unit 1510 is equipped on one side of the fixing seat 153, and the lifting drive mechanism drives the second lifting plate 151 to move, and the sensing sheet 1511 located on one side of the second lifting plate 151 is sensed by the sensing unit 1510;

[0102] The top of the second lifting plate 151 is equipped with a mounting frame, a mounting box 1518 is arranged on one side of the mounting frame, a flip shaft 1513 is arranged on the front side of the mounting frame, the mounting frame includes a mounting plate 1515 and a group of side plates 1516, the side plates 1516 are equipped with bearings 1517, the flip shaft 1513 is arranged between the group of side plates 1516, and the two ends of the flip shaft 1513 are rotatably connected with the bearings 1517, the induction unit 1510 is connected to the flip mechanism for communication, the flip mechanism includes a driving unit 1514 and a transmission module, the transmission module is installed in the interior of the mounting box 1518, the transmission module includes a driving wheel 1519, a driven wheel 1520 and a synchronous belt 1521, the driven wheel 1520 is equipped with At one end of the flip shaft 1513, the driving unit 1514 is connected to the driving wheel 1519 and drives the driven wheel 1520 and the flip shaft 1513 to rotate through the synchronous belt 1521. The driving unit 1514 is mounted on the back of the second lifting plate 151. The product adsorption plate 152 is mounted on the flip shaft 1513. The driving unit 1514 drives the flip shaft 1513 and the product adsorption plate 152 to flip through the transmission module. There is a gap between the product adsorption plate 152 and the mounting plate 1515 to form an active gap for the product adsorption plate 152 to flip, so that the product adsorption plate 152 can be flipped up and down 180 degrees, and can be flipped on the original work station to save space;

[0103] The driving unit 1514 and the driving member 157 are both motors. Compared with the cylinder drive, the motor drive can respond quickly and smoothly. The driving member 157 drives the rotating arm 158 to rotate counterclockwise, and the cam 159 slides inside the movable groove 156 and drives the second lifting plate 151 to slide along the lifting guide rail 154, so as to drive the flipping mechanism and the product adsorption plate 152 to descend. When the second lifting plate 151 is descending, the flipping mechanism runs synchronously, and the driving unit 1514 drives the flipping shaft 1513 and the product adsorption plate 152 to flip 180 degrees through the transmission module. When the cam 159 slides to the rightmost side of the movable groove 156, the second lifting plate 151 drops to the lowest point at this time, and the product adsorption plate 152 adsorbs the product. At the same time, the sensing unit 1510 reaches the sensing unit 1510. After the plate 1511 is moved, a signal is sent to the lifting drive mechanism and the flipping mechanism respectively. The driving member 157 drives the rotating arm 158 to rotate clockwise, and the cam 159 slides inside the movable groove 156 and drives the second lifting plate 151 to slide along the lifting guide rail 154, so as to drive the flipping mechanism and the product adsorption plate 152 to rise. Since the second lifting plate 151 is in the process of rising, the flipping mechanism runs synchronously, and the driving unit 1514 drives the flipping shaft 1513 and the product adsorption plate 152 to flip 180 degrees through the transmission module, so that the product is turned over. When the cam 159 slides to the rightmost side of the movable groove 156, the second lifting plate 151 rises to the highest point at this time, and the product adsorption plate 152 releases the product and waits for the robot arm of the subsequent station to take away the product, completing the product flipping and transportation;

[0104] Two air passages 1522 are arranged inside the flip shaft 1513 and are symmetrically distributed on the left and right sides. The two air passages 1522 are spaced apart from each other, and each air passage 1522 is provided with three air passage ports 1525. The product adsorption plate 152 is provided with adsorption holes 1523 communicating with the air passage ports 1525. Both ends of the flip shaft 1513 are equipped with suction nozzles 1524. One end of the suction nozzle 1524 is communicated with the air passage 1522, and the other end of the suction nozzle 1524 is connected to a vacuum pump. The vacuum pump turns the flip shaft The air inside 1513 is discharged, so that a negative pressure state is formed in the flip shaft 1513, and due to the setting of the two air channels 1522, the gas is more effectively diverted in the flip shaft 1513. When the gas inside the flip shaft 1513 is sucked through the two different air channels 1522, on the one hand, the overall air extraction efficiency can be improved, and on the other hand, the loss of adsorption force when the flip shaft 1513 forms a negative pressure can be effectively reduced, thereby improving the adsorption effect, so that the product is firmly adsorbed on the product adsorption plate 152.

[0105] Compared with traditional technology:

[0106] 1. By setting a second lifting plate 151, a lifting drive mechanism, a product adsorption plate 152 and a flipping mechanism, since the flipping mechanism is installed on the second lifting plate 151, the lifting drive mechanism is connected to the second lifting plate 151 to drive the second lifting plate 151 and the flipping mechanism to lift and lower, and the flipping mechanism is connected to the product adsorption plate 152 to drive the product adsorption plate 152 to flip, thereby integrating the conveying mechanism and the flipping mechanism into one device. On the one hand, the number of required equipment and the floor space are reduced, making the machine layout more compact and significantly improving space utilization. On the other hand, the integrated setting can realize continuous completion of flipping and conveying operations without transferring materials between different devices, avoiding damage to the product when transferring between devices, shortening the operation cycle of key flipping and conveying, and improving the overall operation efficiency of key appearance defect detection.

[0107] 2. Due to the setting of the two air paths 1522 inside the flip plate, the gas can be more effectively diverted inside the flip shaft 1513. When the gas inside the flip shaft 1513 is sucked through the two different air paths 1522, on the one hand, the overall air extraction efficiency can be improved, and on the other hand, the loss of adsorption force when the flip shaft 1513 forms a negative pressure can be effectively reduced, thereby improving the adsorption effect and allowing the product to be firmly adsorbed on the product adsorption plate 152.

[0108] In addition, a spacing module mechanism 160 includes a driving device 1601, a spacing shaft 1602, a guide rail assembly 1603, and a spacing assembly 1604; the spacing shaft 1602 is symmetrically provided with a plurality of spacing grooves 16021 arranged at intervals on both sides of the middle, each spacing groove 16021 is arranged around the outer side of the spacing shaft 1602, and on any axial section passing through and parallel to the central axis of the spacing shaft 1602, a plurality of spacing grooves 16021 are equidistantly distributed; the spacing assembly 1604 includes a plurality of suction nozzles 16041 and a plurality of adsorption mounting parts 16042, wherein each adsorption mounting part 16042 is provided with a mounting slide column 160421 at one end, and the mounting slide column 160421 is slidably fitted on The other end of the adsorption mounting part 16042 is matched with the suction nozzle 16041 in several spacing grooves 16021; the guide rail assembly 1603 is arranged on the outside of the spacing axis 1602, and is provided with at least one linear guide rail 16031 arranged along the spacing axis 1602, and the adsorption mounting part 16042 is slidably set on the linear guide rail 16031, and the driving device 1601 drives the spacing axis 1602 to rotate forward or reverse around the central axis, and enables the adsorption mounting part 16042 to drive the suction nozzle 16041 to move along the spacing groove 16021 of the spacing axis 1602, and the adsorption mounting part 16042 can be guided by the linear guide rail 16031 to move toward the middle linear displacement or separate toward the two sides linear displacement.

[0109] The beneficial effect is that the mechanism drives the spacing shaft 1602 to rotate through the driving device 1601, so that the spacing component 1604 (including the suction nozzle 16041 and the suction mounting part 16042) moves quickly along the spacing groove 16021, thereby realizing the automatic adjustment of the spacing of the suction nozzles 16041. Compared with the traditional manual or single-piece movement method, this automated adjustment method significantly improves production efficiency. The mechanism is compactly designed and realizes a complex spacing adjustment function through simple mechanical transmission (such as drive motor 16011, reducer 16012 and pulley transmission) and cam mechanism. This design not only reduces the number of components, but also reduces the complexity of manufacturing and maintenance.

[0110] The equidistant distribution of the spacing grooves 16021 and the guiding effect of the linear guide rail 16031 make the position control of the suction nozzle 16041 very accurate during the movement. In addition, the setting of the limit sensor 1606 can further ensure that the suction nozzle 16041 stops accurately at a specific position, thereby improving the processing accuracy of the product.

[0111] Since the spacing grooves 16021 are arranged around the outer side of the spacing axis 1602 and the number is adjustable, the number and distribution of the spacing grooves 16021 can be adjusted according to different production requirements to adapt to products of different specifications and spacings. This flexibility enables the mechanism to have a wider range of applications.

[0112] Through precise mechanical transmission and control systems, the mechanism can achieve efficient production while reducing energy consumption. Compared with some complex electronic equipment or hydraulic systems, the mechanism has lower energy consumption, which is conducive to energy conservation and emission reduction. The guide rail assembly 1603 provides a stable guiding effect for the adsorption mounting 16042, so that the suction nozzle 16041 is not easy to deviate or shake during movement. This stability ensures the processing quality of the product and extends the service life of the mechanism. Specifically, when we select any section parallel to the central axis and passing through the central axis on the separation axis 1602 for observation, we will find that the separation grooves 16021 presented on the section are equidistant and evenly distributed. This distribution pattern is not only reflected in a single section, but also in the entire separation axis 1602, that is, all sections parallel to the central axis and passing through the central axis are equally divided. This design ensures that no matter how the separation axis 1602 rotates, the distance between each separation groove 16021 is kept equally divided, providing a stable motion trajectory and accuracy of separation adjustment for the separation mechanism.

[0113] Furthermore, it also includes a frame 1605, a limit sensor 1606 is arranged on the outer side of the frame 1605, and one end of the spacing shaft 1602 installed inside the frame 1605 extends out of the frame 1605 and is equipped with a sensing block 1607 that cooperates with the limit sensor 1606. Further, the limit sensor 1606 includes a starting point sensor 16016 and an end point sensor 16017, and the sensing block 1607 includes a starting point sensing piece 16018 corresponding to the starting point sensor 16016 and an end point sensing piece 16019 corresponding to the end point sensor 16017.

[0114] The frame 1605 is the main structure of the entire variable pitch module mechanism, and is used to support and fix key components such as the drive device 1601, the separation shaft 1602, the guide rail assembly 1603, and the separation assembly 1604. This design ensures the stability and reliability of the mechanism during operation. The limit sensor 1606 (including the starting point sensor 16016 and the end point sensor 16017) is used to monitor the position of the separation shaft 1602 (or more specifically, the sensing block 1607). When the sensing block 1607 moves to a specific position (such as the starting point or the end point), the limit sensor 1606 will send a signal to control the drive device 1601 to stop or change the direction of movement, thereby achieving precise position control. By setting the limit sensor 1606, the separation shaft 1602 can be prevented from exceeding the predetermined range during the rotation process, thereby preventing collision or damage with other components. This is of great significance for protecting the safety of the mechanism and extending its service life. The induction block 1607 is installed at one end of the spacing shaft 1602 and extends outside the frame 1605 to cooperate with the outer limit sensor 1606. When the spacing shaft 1602 rotates, the induction block 1607 moves accordingly, and when it moves into the detection range of the limit sensor 1606, a corresponding signal is triggered.

[0115] Furthermore, a roller 160422 is provided at one end of the sliding column 160421 which is slidably matched with the spacing groove 16021 . The roller 160422 is adaptively built into the spacing groove 16021 , and the outer circumference of the roller 160422 maintains rolling contact with the side walls of the spacing groove 16021 on both sides.

[0116] The design of roller 160422 converts the original sliding friction between slide column 160421 and separation groove 16021 into rolling friction. The resistance of rolling friction is much smaller than that of sliding friction, so it can significantly reduce the energy loss during movement and reduce the wear of slide column 160421 and separation groove 16021, thereby extending the service life of the components. The rolling contact between roller 160422 and the side wall of separation groove 16021 can ensure that the separation component 1604 (including adsorption mounting part 16042 and suction nozzle 16041) is more stable during movement. This stability not only helps to improve the processing accuracy of the product, but also reduces the noise and mechanical stress caused by vibration. In some cases, due to reasons such as processing accuracy or material properties, the slide column 160421 may become stuck with the separation groove 16021. The design of roller 160422 can effectively reduce this risk, because roller 160422 can adaptively adjust the contact state with the side wall of spacing groove 16021 to a certain extent, reducing the occurrence of jamming. Due to the small resistance of rolling friction, spacing component 1604 can respond and move into place more quickly under the action of driving device 1601. This fast response capability is particularly important for production scenarios that require high-speed and high-precision adjustment of the spacing between nozzles 16041.

[0117] Furthermore, the guide rail assembly 1603 is provided with four linear guide rails 16031 distributed at intervals, and the adsorption mounting part 16042 is linearly displaced on and along the four linear guide rails 16031 through the slider 16032. Furthermore, the rear end of the adsorption mounting part 16042 is also provided with at least two mounting and giving way slots 160423 for fitting the slider 16032, wherein at least one mounting and giving way slot 160423 on the adsorption mounting part 16042 is fitted with the slider 16032, the adsorption mounting part 16042 is fitted with the linear guide rail 16031 through the slider 16032, and the sliders 16032 on the two adjacent adsorption mounting parts 16042 on the left and right are not mounted on the same linear guide rail 16031.

[0118] The guide rail assembly 1603 uses four linear guide rails 16031 that are spaced apart. This layout provides a more stable and reliable linear displacement track for the adsorption mounting part 16042. Multiple guide rails can disperse the force and reduce the load pressure of a single guide rail, thereby increasing the service life of the guide rail and the entire mechanism. Through the precise guidance of the four linear guide rails 16031, the stability and accuracy of the adsorption mounting part 16042 during movement can be ensured. This is particularly important for production scenarios that require high-precision positioning.

[0119] Assembly method of adsorption mounting part 16042: At least two assembly clearance slots 160423 are provided at the rear end of the adsorption mounting part 16042, which are used to install the slider 16032 to achieve assembly with the linear guide rail 16031. This design makes the installation position of the slider 16032 more flexible and can be adjusted according to actual needs. In order to avoid the problem of the sliders 16032 interfering with each other when adjacent adsorption mounting parts 16042 are close to each other, a staggered installation method is adopted. That is, the sliders 16032 on the two adjacent adsorption mounting parts 16042 on the left and right are not installed on the same linear guide rail 16031. This design ensures that even when the spacing component 1604 is adjusting the spacing, each adsorption mounting part 16042 can move smoothly along the linear guide rail 16031 without being hindered by adjacent components.

[0120] Specific embodiment: In the embodiment, six adsorption installation parts 16042 are provided, and each adsorption installation part 16042 has four matching recesses 160423 (numbered 1 to 4 from top to bottom). To avoid interference, the first adsorption installation part 16042 installs the slider 16032 in the recesses 1 and 3, while the adjacent second adsorption installation part 16042 installs the slider 16032 in the recesses 2 and 4. This alternating installation method ensures the independence and non-interference of the adsorption installation parts 16042 during movement.

[0121] Furthermore, the driving device 1601 is composed of a driving motor 16011, a reducer 16012, a driving pulley 16013, a driven pulley 16014, and a transmission belt 16015, wherein the output end of the driving motor 16011 is connected to the input end of the reducer 16012, the output end of the reducer 16012 is connected to the driving pulley 16013, and the spacing shaft 1602 is equipped with the driven pulley 16014, and the transmission belt 16015 is respectively arranged between the driving pulley 16013 and the driven pulley 16014.

[0122] As the power source of the entire drive system, the drive motor 16011 is responsible for providing rotational power. Its output end is connected to the input end of the reducer 16012, and the reducer 16012 is driven to work through the high-speed rotation of the motor. The main function of the reducer 16012 is to convert the high-speed and low-torque output of the drive motor 16011 into a low-speed and high-torque output. This is because in practical applications, a lower speed and a larger torque are often required to drive the load (such as the splitter shaft 1602) to work. The output end of the reducer 16012 is connected to the driving pulley 16013 to transmit power to the driving pulley 16013. The driving pulley 16013 and the driven pulley 16014 are key components in the transmission belt 16015 system. The driving pulley 16013 is driven to rotate by the reducer 16012, while the driven pulley 16014 is equipped with the splitter shaft 1602 and connected to the driving pulley 16013 through the transmission belt 16015. When the driving pulley 16013 rotates, it drives the transmission belt 16015 to move, and then drives the driven pulley 16014 and the spacing shaft 1602 to rotate. The transmission belt 16015 is a flexible transmission element connecting the driving pulley 16013 and the driven pulley 16014. It is set between the driving pulley 16013 and the driven pulley 16014, and transmits power through the friction between the belt and the pulley. The transmission belt 16015 has the advantages of simple structure, stable transmission, low noise, etc., and is widely used in various mechanical transmission systems.

[0123] Working principle: When the driving motor 16011 is started, its output end drives the reducer 16012 to rotate. The reducer 16012 converts the high-speed and low-torque motor output into a low-speed and high-torque output, and transmits it to the transmission belt 16015 through the active pulley 16013. The transmission belt 16015 moves under the drive of the active pulley 16013, thereby driving the driven pulley 16014 and the separation shaft 1602 to rotate. Since a plurality of separation grooves 16021 are provided on the separation shaft 1602, and the adsorption mounting part 16042 is slidably fitted in these separation grooves 16021 through the sliding column 160421, the rotation of the separation shaft 1602 will drive the adsorption mounting part 16042 and the suction nozzle 16041 to move along the separation groove 16021, thereby achieving the purpose of separation adjustment.

[0124] Furthermore, the frame 1605 is a rectangular parallelepiped frame structure, and a connecting block 1608 is provided in the middle of the top surface of the frame 1605 for assembly with the end of the second manipulator 80 .

[0125] The frame 1605 is designed as a rectangular frame structure, which has good stability and load-bearing capacity. The various faces of the rectangular frame 1605 remain parallel and vertical, ensuring the stability of the entire mechanism during installation and use. In the middle of the top surface of the frame 1605, a special connecting block 1608 is set. These connecting blocks 1608 are usually precision-machined parts with accurate shapes and sizes to facilitate precise assembly with the end of the robot. The connecting block 1608 not only plays a role in fixing and supporting, but also provides an interface with other equipment or systems. When the variable pitch module mechanism needs to be replaced or maintained, the mechanism can be removed or reinstalled from the end of the second manipulator 80 through simple operations. This quick and detachable design improves the maintenance efficiency and flexibility of the equipment.

[0126] Further, the suction nozzle 16041 includes a negative pressure cylinder 160411 and a cylinder mounting plate 160412, wherein the negative pressure cylinder 160411 is mounted on the cylinder mounting plate 160412, and a plurality of first mounting holes 1604211 are provided on the front side of the adsorption mounting member 16042, and a plurality of second mounting holes 1604121 are provided on the cylinder mounting plate 160412, wherein the second mounting holes 1604121 and the corresponding first mounting holes 1604211 are bolted through to realize the mounting of the two. The structure of the suction nozzle 16041:

[0127] The core component of the suction nozzle 16041 is the negative pressure cylinder 160411, which is responsible for generating negative pressure to adsorb the workpiece. Through its internal mechanical structure, the negative pressure cylinder 160411 can form a certain negative pressure space after ventilation, thereby achieving stable adsorption of the workpiece. The cylinder mounting plate 160412 is a component used to fix and support the negative pressure cylinder 160411. It has sufficient strength and rigidity to ensure that the negative pressure cylinder 160411 can maintain a stable position and posture during operation. At the same time, the cylinder mounting plate 160412 is also designed with an interface or hole position that matches the negative pressure cylinder 160411 to facilitate the precise assembly of the two. The first mounting hole 1604211 and the second mounting hole 1604121: A plurality of first mounting holes 1604211 are arranged on the front side of the adsorption mounting member 16042, and a corresponding plurality of second mounting holes 1604121 are arranged on the cylinder mounting plate 160412. These mounting holes are used to achieve accurate assembly between the suction nozzle 16041 and the suction mounting member 16042. The suction nozzle 16041 is firmly mounted on the suction mounting member 16042 by passing a bolt through the second mounting hole 1604121 on the cylinder mounting plate 160412 and the corresponding first mounting hole 1604211 on the suction mounting member 16042, and fastening with a nut or other fasteners. This connection method is simple and reliable, and is easy to disassemble and maintain.

[0128] Since the suction mounting member 16042 is provided with a plurality of first mounting holes 1604211, and the cylinder mounting plate 160412 is also provided with a plurality of second mounting holes 1604121, it is possible to select a suitable mounting hole position for assembly according to actual needs. This design improves the flexibility of assembly, so that the suction nozzle 16041 can be installed in different positions and directions to meet different work requirements.

[0129] The specific working process of the overall solution is as follows:

[0130] Step 1: Start and power transmission Start the drive device 1601: First, start the drive device 1601, which consists of a drive motor 16011, a reducer 16012, a driving pulley 16013, a driven pulley 16014 and a transmission belt 16015. The drive motor 16011 starts to rotate, and the high-speed and low-torque power is converted into low-speed and high-torque through the reducer 16012, and then transmitted to the driven pulley 16014 through the driving pulley 16013 and the transmission belt 16015, and finally drives the splitter shaft 1602 to rotate.

[0131] Step 2: Rotation of the spacing shaft 1602 and movement of the spacing assembly 1604 As the driving device 1601 works, the spacing shaft 1602 begins to rotate around its central axis. The multiple spacing grooves 16021 provided on the spacing shaft 1602 provide guidance for the adsorption mounting member 16042. These spacing grooves 16021 are evenly distributed when the spacing shaft 1602 rotates, ensuring the stability of the movement of the adsorption mounting member 16042. The mounting slide column 160421 at one end of the adsorption mounting member 16042 slides in the spacing groove 16021 and moves with the rotation of the spacing shaft 1602. At the same time, the suction nozzle 16041 connected to the other end of the adsorption mounting member 16042 also moves accordingly to achieve adsorption and movement of the workpiece. The guide rail assembly 1603 provides guidance for the linear displacement of the adsorption mounting member 16042. By sliding the slider 16032 on the linear guide 16031, the adsorption mounting part 16042 can achieve displacement toward the center or separation toward both sides according to the rotation direction and speed of the separation shaft 1602 while maintaining linear motion. With the continuous rotation of the separation shaft 1602 and the movement of the adsorption mounting part 16042 on the linear guide 16031, the spacing of the suction nozzles 16041 is automatically adjusted to meet different production requirements.

[0132] Step 3: When the dividing shaft 1602 rotates to a preset position, the limit sensor 1606 installed on the outside of the frame 1605 detects the induction block 1607 installed at one end of the dividing shaft 1602, thereby sending a signal to control the driving device 1601 to stop rotating. The setting of the limit sensor 1606 effectively prevents the dividing shaft 1602 from exceeding the preset range of motion, protects the safety of the mechanism, and avoids collision and damage between components.
