Description

Technical Field

[0001] This invention relates to the field of inspection machines, and more particularly to a full-size automatic optical inspection machine with touch keys. Background Technology

[0002] In traditional touch key manufacturing processes, the demand for full-size AOI (Automated Optical Inspection) is increasing. However, existing inspection methods have several shortcomings, mainly including the following:

[0003] Low testing efficiency: Traditional manual or semi-automated testing methods are time-consuming and cannot meet the needs of large-scale production. Furthermore, manual testing is susceptible to subjective factors, making it difficult to guarantee the consistency of test results.

[0004] Insufficient inspection accuracy: Due to limitations in inspection equipment and technology, some appearance defects are difficult to identify accurately, causing defective products to flow into subsequent processes and affecting product quality.

[0005] Low level of automation: Many production lines still rely on a lot of manual operation and cannot achieve full-process automation, which increases production costs and error rates.

[0006] Poor flexibility: Traditional testing equipment often requires extensive adjustments and modifications for different specifications and types of touch key products, which cannot meet the needs of rapid product changeover.

[0007] Low space utilization: Due to the complexity of the testing process, which involves multiple devices and procedures, the production line layout is loose and the space utilization is low.

[0008] Data traceability is difficult: Traditional testing methods lack automatic recording and traceability mechanisms for test results, which makes quality analysis and problem investigation difficult. Summary of the Invention

[0025] Furthermore, the automated flipping and transferring device includes a second lifting plate, a lifting drive mechanism, a product adsorption plate, and a flipping mechanism. The flipping mechanism is installed on the second lifting plate, and the lifting drive mechanism is connected to the second lifting plate to drive the second lifting plate and the flipping mechanism to lift.

This greatly reduces manual intervention and improves production efficiency and inspection speed.

[0031] 2. By setting up multiple inspection cameras, products are photographed and inspected from multiple angles, ensuring that all appearance defects are captured. Simultaneously, the combination of high-magnification inspection cameras and laser scanning technology improves the precision and accuracy of the inspection.

[0058] Please see Figure 1-22 As shown, the present invention relates to a full-size automatic optical inspection machine for touch keys, including a feeding module 10 for feeding products;

[0059] The first appearance defect detection module 30 includes two appearance detection modules. Each appearance detection module includes a turntable 301, multiple support seats 302, and several detection camera devices 305 disposed on one side of the support seats 302 for detecting products from different angles. All support seats 302 are supported by the turntable 301 and are arranged in a circle around the edge of the turntable 301. Each support seat 302 is provided with multiple clamps 303 for holding the product, and each clamp 303 is disposed on the corresponding support seat 302.

[0060] The first robotic arm 20 transfers the product on the feeding module 10 to the clamp 303 on the carrier 302.

[0061] The turntable transfer mechanism 40 (which uses a conventional device currently available on the market, so the specific structure of the device will not be discussed in detail) is located between two appearance inspection modules and picks up and transfers the product from one appearance inspection module to the other appearance inspection module.

[0062] The second appearance defect detection module 50 includes two symmetrically arranged product line buckle detection modules, wherein each product line buckle detection module includes a product carrier 501 and a product line buckle detection camera 502 disposed on one side of the product carrier 501.

[0063] The dual rotary transfer mechanism 1100 transfers the product from another appearance inspection module to two product carriers 501 respectively, and the product line end inspection camera 502 inspects the product on the product carrier 501.

[0064] CCT detection module 60 includes CCT carrier 601 and CCT detection camera 602;

[0065] PPU transfer station 70 (which uses a conventional device currently available on the market, so the specific structure of the device will not be discussed in detail) transfers products from the two product line end detection modules and places them on CCT carrier 601. CCT inspection camera 602 inspects the products on CCT carrier 601.

[0066] An automated flipping and transferring device 15 is located on one side of the CCT carrier 601, which clamps the product and flips it.

[0067] The second robotic arm 80 moves the flipped products to the sorting and loading tray 90 to achieve sorting and unloading.

[0068] The appearance inspection module also includes a barcode scanning mechanism 910 located on one side of the dual rotary transfer mechanism 1100. The barcode scanning mechanism 910 scans the QR code on the product and records the inspection result data.

[0069] Specifically, its workflow is as follows:

[0070] 1. Manually place the feeding tray into the corresponding feeding module 10 position, and then start the equipment;

[0071] 2- The first robotic arm 20 picks up 6 pieces of products from the feeding module 10 and places them into the first appearance inspection module, while the turntable 301 rotates;

[0072] 3- View the left CCD (detection camera device 305) of the foot from above and take multiple pictures of the left foot for detection and record the detection results, then rotate to the next detection station;

[0073] 4. The right-side CCD (inspection camera device 305) of the foot is viewed from above and photographed multiple times to detect and record the detection results. Then it is rotated to enter the next detection station.

[0074] 5. The high-magnification CCD (detection camera device 305) of the foot is used to take pictures of the middle side of the foot and record the detection results. Then it rotates to the next station.

[0075] 6. The scanning mechanism 910 scans the product's QR code, records the test result data, and then rotates to the next station;

[0076] 7-Turntable transfer mechanism 40 picks up the product from the first appearance inspection module and transfers it to the second appearance inspection module, and rotates counterclockwise on turntable 301;

[0077] 8. The side CCD (inspection camera device 305) takes pictures of the side of the product for inspection, records the inspection results, and enters them into the QR code information;

[0078] 9- The high-magnification left-side CCD (inspection camera device 305) of the inner cage is used to photograph and inspect the length and width of the product, and the inspection results are entered into the QR code.

[0079] 10- Top view of the inner cage using a high-magnification right-side CCD (inspection camera device 305) to inspect the relevant dimensions of the product's inner cage and input the inspection results into a QR code;

[0080] 11-Double rotary transfer mechanism 1100 picks up and transfers the product from turntable 301, rotates it, and then places it on both sides of the product line end detection module for the next segment of size detection;

[0081] The product line buckle detection module 502 performs CCD detection on the side foot buckle and records it into the product QR code.

[0082] 13-PPU transfer station 70 picks up and moves the products of the product line buckle detection module and places them on the CCT carriers 601 on both sides for the next stage of detection;

[0083] The 14-CCT inspection camera 602 uses laser scanning to detect dimensions in the product's inner cage that cannot be detected by the CCD, and records the information into the product's QR code;

[0084] 15 - The automated flipping and transferring device 15 picks up the product on the CCT carrier 601, then flips it 180°, and waits for the second robot arm 80 to pick up the material;

[0085] 16-The second robotic arm 80 first picks up the products on the automated flipping and transferring device 15, and then the spacing module mechanism 160 (described in detail below) changes the distance between the 6 products from 22.6mm to 10mm. Then the second robotic arm 80 moves them to the sorting and palletizing 90.

[0086] 17- The second robotic arm 80, according to the OK and NG of the products, places the products into the OK and NG sorting trays in one go according to the instructions 90; after the traying is completed, the operator takes away the OK and NG product trays.

[0087] Specifically, there are two feeding modules 10, which are identical in structure and arranged side by side. One feeding module 10 is responsible for loading materials to form a loading bin 100, and the other feeding module 10 is responsible for unloading materials to form a unloading bin 200. A robotic arm is installed at the subsequent workstation of each feeding module 10 to cooperate with it in loading and unloading. Each 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 pallets 103, each pallet 103 containing a product. When the product on a pallet 103 is grasped by the robotic arm, an empty pallet 103 is formed. The lifting drive mechanism and the... The first lifting plate 110 is connected to drive the first lifting plate 110 to lift relative to the fixed plate 102. The sensing module 105 is used to sense the tray 103 and is controlled and connected to the lifting drive mechanism to control the lifting drive mechanism to drive the first lifting plate 110 to move the tray 103 up and down. The lifting drive mechanism includes a lifting servo motor 118, a mechanism mounting box 117 and a lifting unit installed inside the mechanism mounting box 117. The lifting servo motor 118 is driven and connected to the first lifting plate 110 through the lifting unit. The lifting unit is a traditional structure such as a screw type, gear type, chain drive type or synchronous belt type, which can realize the lifting or lowering movement of the first lifting plate 110.

[0088] It also includes a sensing unit 109 for detecting the height position of the first lifting plate 110, and is connected to the lifting drive mechanism to control the start or stop of the lifting drive mechanism. The first lifting plate 110 is L-shaped, and a sensing block 116 for being sensed by the sensing unit 109 is provided on one side of the first lifting plate 110. In the initial state, the first lifting plate 110 in the unloading hopper 200 is at its highest value, and the first lifting plate 110 in the loading hopper 100 is at its lowest value. When the worker stacks the pallet 103 on the first lifting plate 110 in the loading hopper 100, the sensing block 116 in the loading hopper 100 triggers the sensing unit 109. The sensing unit 109 sends a start signal to the lifting drive mechanism in the loading hopper 100, causing the lifting drive mechanism to drive the first lifting plate 110 to lift the pallet 103 a certain distance. After the sensing module 105 senses the pallet 103, the subsequent mechanical... The robot arm picks up the products from the pallet 103. After all the products on the pallet 103 are removed, the robot arm picks up the empty pallet 103 and puts it into the unloading bin 200. After the sensing module 105 senses the empty pallet 103, the lifting drive mechanism drives the first lifting plate 110 to lower the empty pallet 103 a certain distance. The above steps are repeated until the loading is completed. At this time, the first lifting plate 110 in the loading bin 100 is at its highest value. As the empty pallets 103 are stacked to the maximum value, the sensing block 116 in the unloading bin 200 triggers the sensing unit 109. The sensing unit 109 sends a stop signal to the lifting drive mechanism in the unloading bin 200. The empty pallet 103 is then manually removed and the pallet 103 is stacked back on the first lifting plate 110 in the loading bin 100. This saves manpower from frequent loading and unloading of materials and greatly improves the efficiency of loading and unloading.

[0089] A slot is provided in the middle of the fixed plate 102 to form a material trough 101 for loading or unloading the pallet 103. The fixed plate 102 is provided with a set of positioning components 111 arranged symmetrically on the left and right sides for initial positioning of the pallet 103. The positioning components 111 include a stop rod 107 and four positioning rods 112. Mounting plates 113 are fixedly connected to the left and right sides of the mechanism mounting box 117. The two ends of the positioning rods 112 are respectively connected to the fixed plate 102 and the mounting plate 113, and the inner end of the mounting plate 113 is formed with a mounting protrusion 108 for mounting the stop rod 107. The stop rod 107 and the pallet 103 are connected to each other. The front side of the 03 contacts the pallet 103 to limit its displacement. The positioning rod 112 contacts the left and right sides of the pallet 103, making the pallets 103 stacked flat. The fixing plate 102 is provided with a driving component 106 and four positioning components 104. The positioning components 104 are all L-shaped protrusions and are symmetrically distributed. The driving component 106 is a driving cylinder. The driving cylinder pushes the pallet 103 to move, so that the side of the pallet 103 and the right angle side of the positioning component 104 fit together, so that the positioning component 104 further positions the pallet 103, which makes it easier for the robot in the subsequent station to grasp the product or empty pallet 103.

[0090] Compared with traditional technology: The first lifting plate 110 is used to stack and place the pallet 103. The lifting drive mechanism is connected to the first lifting plate 110 to drive the first lifting plate 110 to rise and fall relative to the fixed plate 102. The sensing module 105 is used to sense the pallet 103 and is controlled and connected to the lifting drive mechanism to control the lifting drive mechanism to drive the first lifting plate 110 to lift and fall the pallet 103. The lifting drive mechanism drives the first lifting plate 110 to lift the pallet 103 a certain distance. Therefore, after the sensing module 105 senses the pallet 103, the subsequent mechanical... The robot arm picks up the product from the pallet 103 by hand, and then picks up the empty pallet 103 and puts it into the unloading bin 200. After the sensing module 105 senses the empty pallet 103, the lifting drive mechanism drives the first lifting plate 110 to lower the empty pallet 103 a certain distance. On the one hand, the pallet 103 can hold multiple buttons to be inspected. On the other hand, the pallet 103 is stacked for loading, so it can supply materials at one time to meet the production needs of the machine. This can effectively avoid the problems of frequent manual loading and unloading and frequent machine stoppages while waiting for material supply, and greatly improve the detection efficiency of button appearance defects.

[0091] Specifically, the dual rotary transfer mechanism 1100 has the following structure: a rotary platform 1101, a horizontal drive component 1102, a vertical drive component 1103, a second rotary drive component 1105, and a vacuum suction component 1106. The rotary platform 1101 is horizontally mounted on the machine base. The output end of the rotary platform 1101 is equipped with the horizontal drive component 1102. The output end of the horizontal drive component 1102 is equipped with the vertical drive component 1103 and the second rotary drive component 1105. The output end of the vertical drive component 1103 is equipped with the vacuum suction component 1106. The vertical drive component 1103 is used to drive the vacuum suction component 1106 to move up and down. The vacuum suction component 1106 is used to pick up the product. The output end of the second rotary drive component 1105 is connected to the vacuum suction component 1106. The second rotary drive component 1105 is used to drive the product to rotate.

[0092] Furthermore, to realize the functions of the drive assembly and vacuum suction assembly 1106 and avoid malfunctions caused by wiring entanglement during rotation, a first fixed mounting plate 11011 is fixedly installed at the output end of the rotating platform 1101. An electric slip ring assembly 1104 is also installed on the machine base. The electric slip ring assembly 1104 has a fixed end 11041 and a rotating end 11042. Power supply and air supply lines pass through the electric slip ring assembly 1104. The fixed end 11041 of the electric slip ring assembly 1104 is connected to the machine base, and the rotating end 11042 of the electric slip ring assembly 1104 is connected to the first fixed mounting plate 11011 via a connecting bracket. The first fixed mounting plate 11011 and the rotating end 11042 rotate synchronously. The air supply line is connected to the vacuum suction assembly 1106.

[0093] Furthermore, a second fixed mounting plate 11021 is installed at the output end of the horizontal drive assembly 1102. A vertical drive assembly 1103 and a second rotary drive assembly 1105 are mounted on the second fixed mounting plate 11021. The vertical drive assembly 1103 includes a vertical drive motor 11031, a third fixed mounting plate 11032, and a vertical slide rail 11033. The vertical slide rail 11033 and the vertical drive motor 11031 are mounted on the second fixed mounting plate 11021. The third fixed mounting plate 11032 is movably mounted on the vertical slide rail 11033. The output end of the vertical drive motor 11031 is connected to the third fixed mounting plate 11032. A connecting plate 110322 is fixedly mounted on the lower end of the third fixed mounting plate 11032. A vacuum suction component 1106 is installed on the lower end of the connecting plate 110322. The vertical drive motor 11031 drives the third fixed mounting plate 11032 and the vacuum suction component 1106 to move in the vertical direction.

[0094] Furthermore, in order to enable the vacuum suction assembly 1106 to pick up and fix products, the vacuum suction assembly 1106 includes a vent 11061, a movable connecting pipe 11062, and a rotary suction nozzle 11063. A plurality of movable connecting pipes 11062 are arranged between the connecting plate 110322 and the second fixed mounting plate 11021. The vertical drive motor 11031 drives the third fixed mounting plate 11032 and the movable connecting pipes 11062 to move vertically. The vent 11061 is installed in the middle of the movable connecting pipe 11062. The lower end of the movable connecting pipe 11062 passes through the second fixed mounting plate 11021 and is connected to the rotary suction nozzle 11063. The rotary suction nozzle 11063 is connected to an external air supply pipeline through the vent 11061. The movable connecting pipe 11062 and the rotary suction nozzle 11063 are driven to rotate by the second rotary drive assembly 1105. The movable connecting pipe 11062 is rotatably connected to the connecting plate 110322 via a movable bearing.

[0095] In one embodiment, six movable connecting tubes 11062 are provided, and six rotating suction nozzles 11063 are driven to rotate synchronously by the second rotation drive assembly 1105.

[0096] Furthermore, to ensure more stable movement of the third fixed mounting plate 11032 and the vacuum suction assembly 1106, the vertical drive motor 11031 is horizontally mounted above the second fixed mounting plate 11021. An eccentric wheel 11034 is connected to the output end of the vertical drive motor 11031. An elliptical movable slot 110321 is provided on the third fixed mounting plate 11032, and the outer side of the eccentric wheel 11034 is movably positioned along the inner wall of the movable slot 110321. When the eccentric wheel 11034 rotates, it pushes the third fixed mounting plate 11032 to move vertically.

[0097] Furthermore, in order to enable the second rotary drive assembly 1105 to drive the vacuum suction assembly 1106 and the product to rotate, the second rotary drive assembly 1105 includes a second rotary drive motor 11051, a pulley assembly 11052, and a rotary bushing 11053. A plurality of rotary bushings 11053 are rotatably mounted on the second fixed mounting plate 11021. The second rotary drive motor 11051 is mounted on the second fixed mounting plate 11021. The output end of the second rotary drive motor 11051 is drivenly connected to the rotary bushing 11053 through the pulley assembly 11052. The movable connecting tube 11062 passes through the inner hole of the rotary bushing 11053, and the inner hole of the rotary bushing 11053 is provided with a limiting groove to restrict the axial rotation of the movable connecting tube 11062. The movable connecting tube 11062 rotates with the rotary bushing 11053 through the limiting groove. The movable connecting tube 11062 is movably mounted along the rotating sleeve 11053. A limit block protrudes from the outer side of the movable connecting tube 11062, and the limit block engages with a limit slot inside the rotating sleeve 11053. The second rotary drive motor 11051 drives the rotating sleeve 11053 to rotate via the pulley assembly 11052. The rotation of the rotating sleeve 11053 causes the movable connecting tube 11062 to rotate axially, thereby driving the product to rotate. The pulley assembly 11052 is sequentially mounted around the outer side of the rotating sleeve 11053.

[0098] This embodiment includes a rotating platform 1101, a horizontal drive component 1102, a vertical drive component 1103, an electric slip ring component 1104, a second rotating drive component 1105, and a vacuum suction component 1106. The horizontal drive component 1102 and the vertical drive component 1103 can move and pick up products. The rotating platform 1101 can drive the product to rotate 360 ​​degrees. The second rotating drive component 1105 can independently control the rotation of the product picked up by the vacuum suction component 1106. This embodiment has a dual-rotation structure, which allows the product to rotate and be placed in both left and right directions. At the same time, the small rotation of the second rotating drive component 1105 can compensate for and correct the rotation angle of the product. This application has a simple and compact structure, occupies little space, and has stable function.

[0099] The present invention provides an automated flipping and transferring device 15, including a second lifting plate 151, a lifting drive mechanism, a product adsorption plate 152 and a flipping mechanism. 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.

[0100] The lifting drive mechanism is a motor eccentric structure, which includes a drive component 157, a rotating arm 158, and a cam 159. A cam 159 is mounted on one end of a rotating arm 158 and is located inside and slidably connected to a movable slot 156. A drive member 157 is mounted on the back of a fixed base 153. The drive member 157 drives the rotating arm 158 to rotate and causes the cam 159 to move the second lifting plate 151. The fixed base 153 is also included. Two lifting guide rails 154 are mounted on the front end of the fixed base 153. A lifting slider 155 that is slidably connected to the lifting guide rails 154 is mounted on the back of the second lifting plate 151. The second lifting plate 151 has a movable slot 156 in the shape of an elongated oval. The fixed base 159 also includes a sensing unit 1510 for detecting the height position of the second lifting plate 151 and communicating with the lifting drive mechanism. The sensing unit 1510 is mounted on one side of the fixed base 153. The lifting drive mechanism drives the second lifting plate 151 to move and causes the sensing plate 1511 located on one side of the second lifting plate 151 to be sensed by the sensing unit 1510.

[0101] The second lifting plate 151 is equipped with a mounting bracket at its top. A mounting box 1518 is located on one side of the mounting bracket. A tilting shaft 1513 is located on the front side of the mounting bracket. The mounting bracket includes a mounting plate 1515 and a set of side plates 1516. Bearings 1517 are mounted on the side plates 1516. The tilting shaft 1513 is located between the side plates 1516, and both ends of the tilting shaft 1513 are rotatably connected to the bearings 1517. The sensing unit 1510 is communicatively connected to the tilting mechanism. The tilting mechanism includes a drive unit 1514 and a transmission module. The transmission module is installed inside the mounting box 1518. The transmission module includes a drive 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 drive unit 1514 is connected to the drive wheel 1519 and drives the driven wheel 1520 and the flip shaft 1513 to rotate via the synchronous belt 1521. The drive 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 drive 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 by 180 degrees. It can also be flipped on the original work station, saving space.

[0102] Both the drive unit 1514 and the drive component 157 are motors. Compared to cylinder drives, motor drives can respond quickly and smoothly. The drive component 157 drives the rotating arm 158 to rotate counterclockwise. The cam 159 slides inside the movable slot 156 and drives the second lifting plate 151 to slide along the lifting guide rail 154, thereby driving the flipping mechanism and the product adsorption plate 152 to descend. During the descent of the second lifting plate 151, the flipping mechanism operates synchronously. The drive 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 slot 156, the second lifting plate 151 descends to its lowest point, and the product adsorption plate 152 adsorbs the product. At the same time, the sensing unit 1510 senses the product. After the plate 1511 is lifted, signals are sent to the lifting drive mechanism and the flipping mechanism respectively. The drive component 157 drives the rotating arm 158 to rotate clockwise. The cam 159 slides inside the movable groove 156 and drives the second lifting plate 151 to slide along the lifting guide rail 154, thereby driving the flipping mechanism and the product adsorption plate 152 to rise. As the second lifting plate 151 rises, the flipping mechanism runs synchronously. The drive 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 flipped. When the cam 159 slides to the rightmost side of the movable groove 156, the second lifting plate 151 rises to the highest point. The product adsorption plate 152 releases the product and waits for the robot arm of the subsequent station to pick up the product, completing the product flipping and handling.

[0103] The rotating shaft 1513 has two symmetrically distributed air passages 1522 inside, spaced apart from each other. Each air passage 1522 has three air inlets 1525. The product adsorption plate 152 has adsorption holes 1523 communicating with the air inlets 1525. Both ends of the rotating shaft 1513 are equipped with suction nozzles 1524. One end of the suction nozzle 1524 is connected to the air passage 1522, and the other end of the suction nozzle 1524 is connected to a vacuum pump. The vacuum pump drives the rotating shaft... The air inside 1513 is discharged, creating a negative pressure state inside the flip shaft 1513. Due to the setting of two air passages 1522, the gas is more effectively diverted inside the flip shaft 1513. When the gas inside the flip shaft 1513 is drawn in through the two different air passages 1522, it can improve the overall air extraction efficiency on the one hand, and effectively reduce the loss of adsorption force when the flip shaft 1513 forms a negative pressure on the other hand, thereby improving the adsorption effect and making the product firmly adsorbed on the product adsorption plate 152.

[0104] Compared to traditional technologies:

[0105] 1. By setting up 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 and 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. The flipping mechanism is connected to the product adsorption plate 152 to drive the product adsorption plate 152 to flip. This integrates the handling mechanism and the flipping mechanism into one device. On the one hand, it reduces the number of required devices and the floor space, making the machine layout more compact and significantly improving the space utilization. On the other hand, the integrated setup can realize continuous flipping and handling operations without transferring materials between different devices, avoiding damage to the product when transferring between devices, and shortening the operation cycle of button flipping and handling, thus improving the overall operation efficiency of button appearance defect detection.

[0106] 2. Due to the arrangement of two air passages 1522 inside the flip plate, the gas is more effectively diverted within the flip shaft 1513. When the gas inside the flip shaft 1513 is drawn through the two different air passages 1522, it can improve the overall gas extraction efficiency on the one hand, and effectively reduce the loss of adsorption force when the flip shaft 1513 forms a negative pressure on the other hand, thereby improving the adsorption effect and making the product firmly adsorbed on the product adsorption plate 152.

[0107] Furthermore, regarding a spacing module mechanism 160, it includes a drive device 1601, a spacing shaft 1602, a guide rail assembly 1603, and a spacing assembly 1604. The spacing shaft 1602 is symmetrically arranged with multiple spaced spacing grooves 16021 on both sides of the center. Each spacing groove 16021 surrounds the outer surface of the spacing shaft 1602, and on any axial cross-section passing through and parallel to the central axis of the spacing shaft 1602, the grooves 16021 are equidistantly distributed. The spacing assembly 1604 includes several suction nozzles 16041 and several suction mounting components 16042, wherein each suction mounting component 16042 has a mounting slide post 160421 at one end, and the mounting slide post 160421 slides in conjunction with... Within several spacing grooves 16021, the other end of the adsorption mounting component 16042 is fitted with the suction nozzle 16041; the guide rail assembly 1603 is located outside the spacing shaft 1602, and has at least one linear guide rail 16031 arranged along the spacing shaft 1602. The adsorption mounting component 16042 is slidably mounted on the linear guide rail 16031. The driving device 1601 drives the spacing shaft 1602 to rotate around the central axis in a forward or reverse direction, causing the adsorption mounting component 16042 to drive the suction nozzle 16041 to move along the spacing grooves 16021 of the spacing shaft 1602. The adsorption mounting component 16042 is guided by the linear guide rail 16031 to move towards the center in a straight line or to separate towards the sides in a straight line.

[0108] Its beneficial effects are as follows: the mechanism drives the pitch shaft 1602 to rotate via the drive device 1601, causing the pitch assembly 1604 (including the suction nozzle 16041 and the suction mounting component 16042) to move rapidly along the pitch groove 16021, thereby achieving automatic adjustment of the spacing of the suction nozzles 16041. This automated adjustment method significantly improves production efficiency compared to the traditional manual or piece-by-piece movement method. The mechanism has a compact design and achieves complex pitch adjustment functions through simple mechanical transmissions (such as the drive motor 16011, reducer 16012, and pulley drive) and a cam mechanism. This design not only reduces the number of parts but also lowers the complexity of manufacturing and maintenance.

[0109] The equidistant distribution of the dividing grooves 16021 and the guiding effect of the linear guide rail 16031 enable highly precise position control of the suction nozzle 16041 during movement. Furthermore, the inclusion of the limit sensor 1606 further ensures accurate stopping of the suction nozzle 16041 at specific locations, improving the product's processing precision.

[0110] Since the spacing grooves 16021 are arranged around the outside of the spacing shaft 1602 and their number is adjustable, the number and distribution of the spacing grooves 16021 can be adjusted according to different production needs, thereby adapting to products of different specifications and spacings. This flexibility makes the mechanism have a wider range of applications.

[0111] Through precise mechanical transmission and control systems, this mechanism achieves high-efficiency production while reducing energy consumption. Compared to some complex electronic or hydraulic systems, this mechanism consumes less energy, contributing to energy conservation and emission reduction. The guide rail assembly 1603 provides stable guidance for the adsorption mounting component 16042, preventing the suction nozzle 16041 from shifting or wobbling during movement. This stability ensures product processing quality and extends the service life of the mechanism. Specifically, when observing any section parallel to and passing through the central axis on the spacing shaft 1602, the spacing grooves 16021 are found to be equidistant and uniformly distributed. This distribution pattern is not only reflected in a single section but also throughout the entire spacing shaft 1602, i.e., in all sections parallel to and passing through the central axis. This design ensures that regardless of how the spacing shaft 1602 rotates, the distance between each spacing groove 16021 remains equally divided, providing a stable motion trajectory and precise spacing adjustment for the spacing mechanism.

[0112] Furthermore, the system also includes a frame 1605, on the outer side of which a limit sensor 1606 is disposed. One end of a spacing shaft 1602, which is mounted inside the frame 1605, extends out of the frame 1605 and is fitted with a sensing block 1607 that cooperates with the limit sensor 1606. Furthermore, the limit sensor 1606 includes a start-point sensor 16016 and an end-point sensor 16017, and the sensing block 1607 includes a start-point sensing element 16018 corresponding to the start-point sensor 16016 and an end-point sensing element 16019 corresponding to the end-point sensor 16017.

[0113] The frame 1605 serves as the main structure of the entire variable pitch module mechanism, supporting and fixing key components such as the drive unit 1601, the pitch shaft 1602, the guide rail assembly 1603, and the pitch assembly 1604. This design ensures the stability and reliability of the mechanism during operation. Limit sensors 1606 (including a start-point sensor 16016 and an end-point sensor 16017) monitor the position of the pitch shaft 1602 (or more specifically, the sensing block 1607). When the sensing block 1607 moves to a specific position (such as the start or end point), the limit sensor 1606 sends a signal to control the drive unit 1601 to stop or change its direction of movement, thereby achieving precise position control. By setting the limit sensor 1606, the pitch shaft 1602 can be prevented from exceeding a predetermined range during rotation, thus preventing collisions or damage to other components. This is of great significance for protecting the safety of the mechanism and extending its service life. The sensing block 1607 is mounted on one end of the dividing shaft 1602 and extends beyond the frame 1605 to cooperate with the outer limit sensor 1606. When the dividing shaft 1602 rotates, the sensing block 1607 moves accordingly, and when it moves into the detection range of the limit sensor 1606, it triggers a corresponding signal.

[0114] Furthermore, a roller 160422 is provided at one end of the sliding column 160421 that is slidably fitted to the spacing groove 16021. The roller 160422 is adapted to be built into the spacing groove 16021, and the outer circumference of the roller 160422 maintains rolling contact with the side walls of the two sides of the spacing groove 16021.

[0115] The design of roller 160422 transforms the sliding friction between slide column 160421 and spacing groove 16021 into rolling friction. Rolling friction has significantly less resistance than sliding friction, thus greatly reducing energy loss during movement and decreasing wear on slide column 160421 and spacing groove 16021, thereby extending the service life of the components. The rolling contact between roller 160422 and the sidewall of spacing groove 16021 ensures smoother movement of the spacing assembly 1604 (including suction mount 16042 and suction nozzle 16041). This smoothness not only helps improve the processing accuracy of the product but also reduces noise and mechanical stress caused by vibration. In some cases, due to factors such as processing accuracy or material properties, jamming may occur between slide column 160421 and spacing groove 16021. The design of roller 160422 effectively reduces this risk because it can adaptively adjust its contact with the sidewall of the spacing groove 16021 to a certain extent, reducing the occurrence of jamming. Due to the low resistance of rolling friction, the spacing assembly 1604 can respond and move into position more quickly under the action of the drive device 1601. This rapid response capability is particularly important for production scenarios that require high-speed and high-precision adjustment of the nozzle 16041 spacing.

[0116] Furthermore, the guide rail assembly 1603 is provided with four spaced linear guide rails 16031. The adsorption mounting member 16042 is mounted on the four linear guide rails 16031 via a slider 16032 and moves linearly along the four linear guide rails 16031. Furthermore, the rear end of the adsorption mounting member 16042 is also provided with at least two mounting clearance slots 160423 for mounting the slider 16032. At least one mounting clearance slot 160423 on the adsorption mounting member 16042 is fitted with a slider 16032. The adsorption mounting member 16042 is mounted to the linear guide rail 16031 via the slider 16032. The sliders 16032 on two adjacent adsorption mounting members 16042 are not mounted on the same linear guide rail 16031.

[0117] The guide rail assembly 1603 employs four spaced linear guide rails 16031, a layout that provides a more stable and reliable linear displacement track for the adsorption mount 16042. Multiple guide rails distribute the force, reducing the load on individual rails and thus extending the service life of the guide rails and the entire mechanism. The precise guidance of the four linear guide rails 16031 ensures the stability and accuracy of the adsorption mount 16042 during movement. This is particularly important for production scenarios requiring high-precision positioning.

[0118] The mounting method of the adsorption mounting component 16042: At least two mounting clearance slots 160423 are provided at the rear end of the adsorption mounting component 16042 for mounting the slider 16032 to achieve mounting 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. To avoid interference between the sliders 16032 when adjacent adsorption mounting components 16042 are close to each other, a staggered installation method is adopted. That is, the sliders 16032 on two adjacent adsorption mounting components 16042 are not mounted on the same linear guide rail 16031. This design ensures that even during the adjustment of the spacing of the spacing assembly 1604, each adsorption mounting component 16042 can move smoothly along the linear guide rail 16031 without being obstructed by adjacent components.

[0119] Specific Embodiment: In this embodiment, six adsorption mounting components 16042 are provided, each with four fitting clearance slots 160423 (numbered 1 to 4 from top to bottom). To avoid interference, the first adsorption mounting component 16042 has sliders 16032 installed in slots 1 and 3, while the adjacent second adsorption mounting component 16042 has sliders 16032 installed in slots 2 and 4. This alternating installation method ensures the independence and non-interference of the adsorption mounting components 16042 during movement.

[0120] Furthermore, the drive device 1601 comprises a drive motor 16011, a reducer 16012, a drive pulley 16013, a driven pulley 16014, and a transmission belt 16015. The output end of the drive motor 16011 is connected to the input end of the reducer 16012, the output end of the reducer 16012 is connected to the drive pulley 16013, the pitch shaft 1602 is fitted with the driven pulley 16014, and the transmission belt 16015 is respectively sleeved between the drive pulley 16013 and the driven pulley 16014.

[0121] As the power source of the entire drive system, the drive motor 16011 provides rotational power. Its output is connected to the input of the reducer 16012, driving the reducer 16012 through the high-speed rotation of the motor. The main function of the reducer 16012 is to convert the high-speed, low-torque output of the drive motor 16011 into a low-speed, high-torque output. This is because in practical applications, lower speeds and higher torques are often required to drive loads (such as the pitch shaft 1602). The output of the reducer 16012 is connected to the drive pulley 16013, transmitting power to it. The drive pulley 16013 and the driven pulley 16014 are key components in the transmission belt 16015 system. The drive pulley 16013 is driven to rotate by the reducer 16012, while the driven pulley 16014 is fitted to the pitch shaft 1602 and connected to the drive pulley 16013 via the transmission belt 16015. When the driving pulley 16013 rotates, it drives the transmission belt 16015 to move, which in turn drives the driven pulley 16014 and the pitch 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 sleeved between the driving pulley 16013 and the driven pulley 16014, transmitting power through the friction between the belt and the pulleys. The transmission belt 16015 has advantages such as simple structure, smooth transmission, and low noise, and is widely used in various mechanical transmission systems.

[0122] Working principle: When the drive motor 16011 starts, its output drives the reducer 16012 to rotate. The reducer 16012 converts the high-speed, low-torque motor output into a low-speed, high-torque output, which is transmitted to the transmission belt 16015 via the drive pulley 16013. The transmission belt 16015 moves under the drive of the drive pulley 16013, thereby driving the driven pulley 16014 and the pitch shaft 1602 to rotate. Since the pitch shaft 1602 has multiple pitch grooves 16021, and the adsorption mounting component 16042 slides within these pitch grooves 16021 via the sliding column 160421, the rotation of the pitch shaft 1602 will drive the adsorption mounting component 16042 and the suction nozzle 16041 to move along the pitch grooves 16021, thereby achieving the purpose of pitch adjustment.

[0123] Furthermore, the frame 1605 is a cuboid 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 robotic arm 80.

[0124] Frame 1605 is designed as a cuboid frame structure, which offers excellent stability and load-bearing capacity. All faces of the cuboid frame 1605 remain parallel and perpendicular, ensuring the stability of the entire mechanism during installation and use. A dedicated connecting block 1608 is located in the center of the top surface of frame 1605. These connecting blocks 1608 are typically precision-machined components with accurate shapes and dimensions for precise assembly with the robot end effector. The connecting block 1608 not only provides fixation and support but also offers interfaces to other devices or systems. When it is necessary to replace or maintain the pitch module mechanism, the mechanism can be easily detached from or reinstalled on the end effector of the second robot arm 80. This quick-detachable design improves the efficiency and flexibility of equipment maintenance.

[0125] Furthermore, the suction nozzle 16041 includes a negative pressure cylinder 160411 and a cylinder mounting plate 160412. The negative pressure cylinder 160411 is mounted on the cylinder mounting plate 160412, and the front side of the suction mounting component 16042 is provided with a plurality of first mounting holes 1604211, while the cylinder mounting plate 160412 is provided with a plurality of second mounting holes 1604121. The two are mounted by bolts passing through the second mounting holes 1604121 and the corresponding first mounting holes 1604211. The structure of the suction nozzle 16041 is as follows:

[0126] 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 create a certain negative pressure space after air is introduced, 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 interfaces or holes that match the negative pressure cylinder 160411 to facilitate precise assembly. First mounting holes 1604211 and second mounting holes 1604121: Several first mounting holes 1604211 are provided on the front side of the adsorption mounting component 16042, while several corresponding second mounting holes 1604121 are provided on the cylinder mounting plate 160412. These mounting holes are used to achieve precise assembly between the suction nozzle 16041 and the adsorption mounting component 16042. The suction nozzle 16041 is securely mounted on the adsorption mounting component 16042 by bolts passing through the second mounting hole 1604121 on the cylinder mounting plate 160412 and the corresponding first mounting hole 1604211 on the adsorption mounting component 16042, and then tightened with nuts or other fasteners. This connection method is simple, reliable, and facilitates disassembly and maintenance.

[0127] Because the adsorption mounting component 16042 has multiple first mounting holes 1604211, and the cylinder mounting plate 160412 also has multiple corresponding second mounting holes 1604121, the appropriate mounting hole position can be selected for assembly according to actual needs. This design improves assembly flexibility, allowing the suction nozzle 16041 to be installed in different positions and directions to adapt to different working requirements.

[0128] The specific work process of the overall plan is as follows:

[0129] Step 1: Start-up and Power Transmission Start the drive unit 1601: First, start the drive unit 1601, which consists of a drive motor 16011, a reducer 16012, a drive pulley 16013, a driven pulley 16014, and a transmission belt 16015. The drive motor 16011 starts rotating, and the reducer 16012 converts the high-speed, low-torque power into low-speed, high-torque power, which is then transmitted to the driven pulley 16014 through the drive pulley 16013 and the transmission belt 16015, ultimately driving the pitch shaft 1602 to rotate.

[0130] Step 2: Rotation of the Splitting Shaft 1602 and Movement of the Splitting Assembly 1604. With the operation of the drive device 1601, the splitting shaft 1602 begins to rotate around its central axis. Multiple splitting grooves 16021 on the splitting shaft 1602 provide guidance for the adsorption mounting component 16042. These grooves 16021 remain equidistantly distributed as the splitting shaft 1602 rotates, ensuring the stability of the movement of the adsorption mounting component 16042. The mounting slide 160421 at one end of the adsorption mounting component 16042 slides within the splitting groove 16021 and moves with the rotation of the splitting shaft 1602. Simultaneously, the suction nozzle 16041 connected to the other end of the adsorption mounting component 16042 also moves, realizing the adsorption and movement of the workpiece. The guide rail assembly 1603 provides linear displacement guidance for the adsorption mounting component 16042. By sliding the slider 16032 on the linear guide rail 16031, the adsorption mounting component 16042 can maintain linear motion while shifting towards the center or separating to the sides according to the rotation direction and speed of the spacing shaft 1602. As the spacing shaft 1602 continues to rotate and the adsorption mounting component 16042 moves on the linear guide rail 16031, the spacing of the suction nozzles 16041 is automatically adjusted to adapt to different production needs.

[0131] Step 3: When the pitch shaft 1602 rotates to the preset position, the limit sensor 1606 installed on the outside of the frame 1605 will detect the sensing block 1607 installed at one end of the pitch shaft 1602, thereby sending a signal to control the drive device 1601 to stop rotating. The setting of the limit sensor 1606 effectively prevents the pitch shaft 1602 from exceeding the predetermined range of motion, protects the safety of the mechanism, and avoids collisions and damage between components.

Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
