After controlling the suction cup assembly 9 to absorb the metal frame 13, the Z-axis moving assembly 75 drives the suction cup assembly 9 upward. The X-axis moving assembly 72 and the Y-axis moving assembly 74 then move the metal frame 13 to the top of the inspection box 5. The Z-axis moving assembly 75 descends again and places the metal frame 13 into the inspection box 5 (through the placement hole 521 described below, into the box body 51) for inspection.

[0103] After the inspection is completed, the automatic pick-up and placement device 7 takes the metal frame 13 out of the inspection box 5 again. If the metal frame 13 passes the inspection, the automatic pick-up and placement device 7 moves the metal frame 13 back to the conveying mechanism 2; if it fails the inspection, the automatic pick-up and placement device 7 moves the metal frame 13 to the collecting channel 10 and finally enters the collection box 11.

[0104] Strip three 92 can slide in the front-to-back direction within the slot of the U-shaped block 917, and through hole one 94, it can be engaged with hole two 95 at different positions (secured by connecting members such as bolts), thereby achieving front-to-back position adjustment of strip three 92, thereby changing the layout of the suction cup assembly. Strip three 92 can slide in the front-to-back direction within the slot of the U-shaped block 917, and through hole one 94, it can be engaged with hole two 95 at different positions (secured by connecting members such as bolts or pins), thereby achieving front-to-back position adjustment of strip three 92, thereby adjusting the front-to-back spacing between strip three 92 and strip one 9101, thereby changing the layout of the suction cup assembly.

[0105] The suction cup assembly is inserted into the strip hole 93 through the vertical rod 2 96 and can slide left and right along the strip hole 93 to the target position. When the suction cup assembly slides to the desired position, the vertical screw 915 is rotated to move it downward, and the protrusion 9151 at the lower end of the vertical screw 915 pushes the slide bar 99 to slide downward against the elastic force of the spring 1 911. At this time, the inclined surface 1 910 at the lower end of the slide bar 99 contacts the inclined surface 2 914 of the horizontal block 913, forcing the horizontal blocks 913 on the front and rear sides to move away from each other until the ends of the horizontal blocks 913 are stuck in the limiting grooves 931 on both sides of the strip hole 93, thereby locking the position of the suction cup assembly. By loosening the vertical screw 915, the spring 1 911 resets the slide bar 99, and the horizontal block 913 disengages the limiting groove 931, and the suction cup assembly can be slid to the new position again. Repeat the above locking steps to achieve flexible adjustment of the distance between the left and right suction cups.

[0106] The beneficial effects of the above technical solution are:

[0107] The combination of the X-axis moving assembly 72, the Y-axis moving assembly 74, and the Z-axis moving assembly 75 enables the automatic pick-and-place device 7 to move precisely in three-dimensional space, ensuring that the suction cup device 9 accurately reaches the designated position of the metal frame 13, achieving reliable pick-and-place operations, and improving the degree of production automation and operational accuracy.

[0108] The forward and backward sliding of the strip three 92 can change the relative position of the suction cup assembly in the forward and backward directions, and cooperate with the left and right adjustment of the strip hole 93 to achieve two-dimensional layout adjustment. By adjusting the distance between the suction cups, the same set of devices can adapt to metal frames of different sizes and shapes, reducing equipment replacement costs and improving the flexibility of the production line. The locking structure of the limit groove 931 and the horizontal block 913 provides a reliable fixing force, and the suction cup assembly does not move, avoiding the risk of falling. No complicated tools are required, and the spacing adjustment can be completed by rotating the vertical screw 915. It is easy to operate, saves changeover time, and improves production efficiency. The adjustment mechanism is integrated inside the suction cup assembly and does not take up additional space. It is suitable for use in limited installation environments (such as the end effector of an automatic pick-and-place device). The equidistant design of the limit groove 931 allows precise control of the suction cup spacing to meet high-precision assembly requirements.

[0109] Example 3, based on Example 1 or 2, Figure 5 As shown, the detection box 5 includes a box body 51, a box cover 52 is detachably provided on the upper end of the box body 51, a placement hole 521 is provided in the middle of the box cover 52, and a thickness detection device 8 is provided in the box body 51. The thickness detection device 8 includes:

[0110] A placement groove 81 is provided at the middle portion of the lower end of the box body 51 and is used to place the metal frame 13;

[0111] Four sets of thickness detection components are respectively arranged on the front, back, left and right sides of the placement slot 81. The thickness detection components on the front side include:

[0112] A horizontal electric telescopic rod 82, the fixed end of which is fixedly connected to the front inner wall of the box body 51, the telescopic end at the rear end of the horizontal electric telescopic rod 82 is connected to plate 1 83, the upper end of plate 1 83 is installed with plate 2 84, and the lower end of plate 2 84 is installed with several thickness detection devices.

[0113] Optionally, a plurality of metal frame 13 wall thickness detection devices (which are existing wall thickness detection devices) are provided on the rear side of the plate 1 83 .

[0114] The working principle of the above technical solution is as follows: After the automatic pick-and-place device 7 removes the metal frame 13 from the conveyor mechanism 2, it moves three-dimensionally to place the metal frame 13 through the placement hole 521 of the box cover 52 and into the placement slot 81 in the box body 51, completing the positioning work before inspection. The box cover 52 and the box body 51 are in the installed state, forming a closed inspection space.

[0115] Four sets of thickness detection components are arranged around the placement slot 81. For example, the front thickness detection component is activated when the horizontal electric telescopic rod 82 is activated, and its telescopic end drives plate 1 83 to extend forward or retract backward. When the metal frame 13 is placed in the placement slot 81, the horizontal electric telescopic rod 82 extends, causing plate 1 83 to move plate 2 84 and the thickness detection device mounted at the lower end of plate 2 84 toward the front surface of the metal frame 13. The thickness detection device (such as a laser rangefinder, ultrasonic rangefinder, etc.) begins operating, measuring the thickness of the front side of the metal frame 13 by transmitting and receiving signals. Simultaneously, the wall thickness detection device embedded in the back side of plate 1 83 (such as an eddy current thickness gauge, or a pressure sensor, which determines whether the wall thickness meets the standard by comparing the actual detection values ​​of all pressure sensors with the corresponding standard detection values) also begins to detect the wall thickness of the metal frame 13 and obtain wall thickness data. The thickness detection components on the back, left, and right sides of the placement slot 81 operate in the same way as the front side, thereby achieving comprehensive thickness detection of the metal frame 13 from all four directions: front, back, left, and right. The thickness detection device and the wall thickness detection device transmit the detected data to the external control system, which analyzes and processes the data to determine whether the thickness and wall thickness of the metal frame 13 meet the standard requirements, and feeds the results back to the automatic pick-and-place device 7 so that qualified and unqualified metal frames 13 can be subsequently processed differently.

[0116] After the test is complete, the horizontal electric telescopic rod 82 retracts, resetting the detection device. The automatic pick-and-place mechanism 7 operates again, removing the metal frame 13 from the placement slot 81. Based on the test results fed back by the control system, qualified metal frames 13 are returned to the conveyor mechanism 2, while unqualified metal frames 13 are sent to the collection channel 10. If the detection device needs to be replaced or maintenance is required on the interior of the box 51, the box cover 52 can be removed from the box 51.

[0117] The beneficial effects of the above technical solution are:

[0118] By setting thickness detection components on the front, back, left and right sides of the placement slot 81, the thickness and wall thickness of the four main sides of the metal frame 13 can be detected simultaneously, avoiding blind spots in detection, ensuring that the detection data is comprehensive and accurate, and effectively protecting the quality of the tablet computer's metal frame.

[0119] The horizontal electric telescopic rod 82 automatically drives the detection device to move closer to or away from the metal frame 13 without manual operation. It works in conjunction with the automatic pick-and-place device 7 to achieve full automation of the detection process, improve detection efficiency, and reduce labor costs and human operation errors.

[0120] The box cover 52 is designed to be detachable, which makes it easy for staff to maintain, repair or replace the detection device inside the box 51, ensuring long-term stable operation of the equipment; at the same time, the detection components are modularly designed, and each component works independently. If a group fails, it is easy to locate and repair it quickly without affecting the overall detection process.

[0121] The horizontal electric telescopic rod 82 can flexibly adjust the extension length of the detection device according to the size of the metal frame 13 of different specifications, so that the detection device can adapt to the detection of metal frames of tablet computers of various models and sizes, thereby improving the versatility and applicability of the equipment.

[0122] Example 4, based on any one of Examples 1-3, Figure 6 、 Figure 7 As shown, the automatic cleaning device 6 includes:

[0123] A cleaning box 61, the front and rear ends of the cleaning box 61 are respectively installed at the front and rear of the conveying frame 1, and the lower end of the cleaning box 61 is open;

[0124] The vertical electric telescopic rod 62 has an upper end mounted on the inner wall of the upper end of the cleaning box 61 , and a cleaning mechanism is connected to the lower end of the cleaning box 61 .

[0125] Cleaning agencies include:

[0126] Plate three 63 is fixedly connected to the lower end of the vertical electric telescopic rod 62. Extensions 631 are symmetrically provided on the front and rear sides of the lower portion of plate three 63. A slope three 632 with a higher front and lower rear portion is provided in front of the rear extension 631. A vertical connecting rod 64 is fixedly connected to the middle of the lower end of plate three 63. The lower end of the vertical connecting rod 64 is fixedly connected to a hollow block 65. The lower end of the hollow block 65 is connected to a brush 66. An air inlet hole 651 is provided at the upper end of the hollow block 65, and a plurality of air outlet holes 652 are provided at horizontal intervals at the lower end of the hollow block 65.

[0127] Two sets of front-to-back symmetrical centering components are respectively connected to the inner walls of the cleaning box 61 at the front and rear sides, and are used to center the metal frame 13 in the front-to-back direction;

[0128] Compressed gas storage tank 67 is fixedly connected to the inner wall of the upper end of the cleaning box 61, and the outlet hole of the compressed gas storage tank 67 is connected to the vertical outlet pipe 68.

[0129] The ventilation assembly is used to connect or disconnect the vertical air outlet pipe 68 and the air inlet hole 651. The vertical electric telescopic rod 62 is also used to drive two sets of centering assemblies for centering the metal frame 13 in the front and rear directions and connecting the vertical air outlet pipe 68 and the air inlet hole 651 with the ventilation assembly.

[0130] The centering assembly on the rear side includes: a fixing frame 69, which is fixedly connected to the inner wall of the cleaning box 61 on the rear side; a fixing block 3 610 including a vertical block 6101, a sliding block 6102, and an inclined portion 1 6103; a sliding block 6102 is provided on the rear side of the vertical block 6101; an inclined portion 1 6103 is provided on the upper end of the vertical block 6101; the sliding block 6102 slides through the fixing frame 69 along the front-to-back direction; a spring 2 6104 is connected between the rear side of the vertical block 6101 and the inner wall of the cleaning box 61 on the rear side; a inclined portion 4 611 with a higher front and a lower rear is provided on the rear side of the inclined portion 1 6103; and the inclined portion 3 632 cooperates with the inclined portion 4 611;

[0131] The ventilation assembly includes: a horizontal slider 612, which is slidably connected to a fixed plate 613 along the front-to-back direction, and the fixed plate 613 is fixedly connected to the inner wall of the cleaning box 61 on the rear side. A cavity 614 is provided inside the horizontal slider 612, and a second inclined surface 619 is integrally provided at the front of the horizontal slider 612. A fifth inclined surface 617 with a lower front and a higher rear side is provided on the second inclined surface 619. An air inlet 2 6141 is provided at the upper end of the cavity 614, an air outlet 2 6142 and one end of a hose 615 are provided at the lower end of the cavity 614, and the other end of the hose 615 is connected to the air inlet 1 651. A spring 3 12 is connected between the horizontal slider 612 and the inner wall of the cleaning box 61 on the rear side. A connecting frame 616 is detachably connected to the upper end of the plate 3 63. A sixth inclined surface 618 with a lower front and a higher rear side is provided at the lower rear end of the connecting frame 616, and the fifth inclined surface 617 is in contact with the sixth inclined surface 618.

[0132] The compressed gas storage tank 67 can be connected to a compressed gas generating device; the present invention further provides a dust collection box 14 at the upper end of the cleaning box 61, a dust collection device is provided in the dust collection box, and a dust collection port of the dust collection device is connected to the interior of the cleaning box 61 through a dust collection pipe;

[0133] The working principle of the above technical solution is: when the metal frame 13 has not entered the cleaning box 61, the vertical electric telescopic rod 62 is in a retracted state, and the cleaning mechanism is in a high position. The sliding block 6102 in the centering component is acted upon by spring 2 6104, and the distance between the two sliding blocks 6102 in the front-to-back direction is greater than the width of the metal frame 13 (in the front-to-back direction). The horizontal slider 612 in the ventilation component is acted upon by spring 3 12, so that the vertical air outlet pipe 68 (specifically the air outlet three at the lower end of the vertical air outlet pipe 68) and the air inlet hole 2 6141 are in a disconnected state.

[0134] When the conveying mechanism 2 conveys the metal frame 13 into the cleaning box 61, the metal frame 13 is located between the two sets of centering components. The vertical electric telescopic rod 62 starts and extends downward, driving the plate three 63 to descend. During the descent of the plate three 63, the inclined surface three 632 of the extension part 631 contacts the inclined surface four 611 of the fixed block three 610 in the centering component. As the plate three 63 continues to descend, the inclined surface three 632 pushes the inclined surface four 611, so that the two fixed blocks three 610 are close to each other, so that the center line of the front-to-back direction of the metal frame 13 coincides with the center line of the front-to-back direction of the conveying mechanism (which can be the center line of the width direction of the belt in the belt conveyor device), so that the metal frame 13 can enter the installation box 4 accurately and prevent the metal frame 13 from moving forward. At the same time, inclined surface 618 of the connecting bracket 616 at the upper end of plate 3 63 contacts inclined surface 5 617 of the horizontal slider 612 in the ventilation assembly. As plate 3 63 descends, inclined surface 618 pushes inclined surface 5 617, causing the horizontal slider 612 to slide backward, compressing spring 3 12. The second air inlet 6141 in the internal cavity 614 of the horizontal slider 612 communicates with the vertical air outlet pipe 68. The second air outlet 6142 communicates with the first air inlet 651 of the hollow block 65 through the hose 615, completing the ventilation assembly connection operation. The compressed gas in the compressed gas storage tank 67 enters the cavity 614 of the horizontal slider 612 through the vertical air outlet pipe 68 and the second air inlet 6141. Then, it enters the hollow block 65 through the second air outlet 6142, the hose 615, and the first air inlet 651, and finally is ejected from the first air outlet 652. At the same time, the brush 66 contacts the surface of the metal frame 13 as the plate three 63 descends. The airflow generated by the compressed gas spray cooperates with the brush 66 to blow and brush the surface of the metal frame 13 to remove dust and other foreign matter.

[0135] After cleaning is complete, the vertical electric telescopic rod 62 retracts upward, driving the cleaning mechanism upward. The sliding block 6102 in the centering assembly returns forward under the elastic force of spring 2 6104, and the horizontal slider 612 in the ventilation assembly returns under the elastic force of spring 3 12. The vertical air outlet pipe 68 is disconnected from the first air inlet 651, and the cleaning mechanism returns to its initial state. The metal frame 13 is then transported by the conveying mechanism 2 to the next process.

[0136] The beneficial effects of the above technical solution are: through the single drive of the vertical electric telescopic rod 62, the front-to-back alignment of the metal frame 13 and the connection of the ventilation components are simultaneously achieved, which simplifies the mechanism design, reduces the number of driving components, reduces equipment costs and failure rates, and improves the degree of automation and continuity of cleaning operations.

[0137] The cleaning method combining compressed gas blowing and brush cleaning can effectively remove dust and other foreign matter on the surface of the metal frame 13. Compared with a single cleaning method, the cleaning efficiency and cleaning quality are significantly improved, ensuring the accuracy of subsequent detection.

[0138] The centering component utilizes a bevel fit and spring return design to adapt to metal frames 13 of different widths. It automatically centers before cleaning to ensure that the metal frame 13 is in the center of the cleaning mechanism, thereby improving the uniformity and stability of cleaning, enhancing the versatility of the equipment, and ensuring that the metal frame 13 enters the installation box 4 in an accurate position, thereby preventing the metal frame 13 from deviating in the front and rear directions.

[0139] The cleaning mechanism, centering assembly and ventilation assembly are compactly arranged and installed in the cleaning box 61, taking up little space and being easy to integrate into the production line; at the same time, each component is modularly designed, and some parts (such as the connecting frame 616) are detachable, which is convenient for later maintenance and replacement of wearing parts.

[0140] The compressed gas storage tank 67 provides the gas required for cleaning on demand, which reduces the waste of compressed gas compared to the continuous gas supply method; and through the reasonable design of the gas path and cleaning process, energy consumption is reduced while ensuring the cleaning effect.

[0141] Example 5, based on any one of Examples 1-4, the suction cup device 9 includes multiple suction cups 918 (vacuum suction cups), and the thickness detection system further includes a control and early warning device, which includes:

[0142] Air pressure sensor: Each suction cup 918 is provided with an air pressure sensor. Each time the suction cup 918 performs the first suction operation, the air pressure sensor is controlled to perform multiple detections. The first suction operation is to perform the suction operation on the conveying mechanism 2.

[0143] Timer: used to count the working time of each first material suction work of the suction cup 918 (the timer is reset each time the first material suction work is completed);

[0144] Temperature detection device: used to detect ambient temperature;

[0145] Speed ​​detection device: used to detect the conveying speed of the conveying mechanism 2;

[0146] A first determining module is used to determine a target control parameter of the suction cup 918 during each first material suction operation, wherein the target control parameter is determined based on a detection value of a temperature detection device before each first material suction operation of the suction cup 918;

[0147] The first control module is used to control the suction cup 918 to perform the corresponding first suction operation according to the target control parameters of each first suction operation;

[0148] The second determining module is used to determine the corresponding target conveying speed based on the target control parameters of the suction cup 918 during each first material suction operation and the detection value of the speed detection device before each first material suction operation of the suction cup 918;

[0149] The second control module is used to control the conveying speed of the conveying mechanism 2 to the corresponding target conveying speed before each first material suction operation of the suction cup 918 (the conveying speed of the conveying mechanism 2 will be adjusted again when the target conveying speed determined by the second determination module changes next time).

[0150] An acquisition module is used to obtain a change curve of the working time of the suction cup 918 and the standard value of the air pressure in the suction cup 918 under the target control parameters (the horizontal axis is the working time of the suction cup 918, the vertical axis is the standard value of the air pressure in the suction cup 918, and the horizontal axis starts from 0);

[0151] Calculation module: used to calculate the air pressure difference of each suction cup 918 each time the suction cup 918 works for the first time based on the air pressure sensor detection value of the suction cup 918 each time the suction cup 918 works for the first time and the acquisition result of the acquisition module;

[0152] Early warning module: used for issuing an early warning when the air pressure difference of any suction cup 918 is greater than the corresponding preset difference each time the suction cup 918 performs the first material suction operation.

[0153] The target control parameters of the suction cup 918 during each first suction operation are determined based on the detection value of the temperature detection device before each first suction operation of the suction cup 918, specifically:

[0154] A preset table is provided for mapping the ambient temperature to the first control parameter when the suction cup 918 is working in a single suction operation (different first control parameters are set for different metal frames 13). The table is obtained through an experiment based on the initial use of the suction cup device 9. The suction effect under the first control parameter meets the requirements.

[0155] Determine in the above mapping table that the first control parameter corresponding to the detection value of the temperature detection device of the suction cup 918 before the first suction operation is the first control parameter of the suction cup 918 during the first suction operation;

[0156] The first control parameters include: a first pumping rate and a first pumping time;

[0157] The target control parameters include: a target pumping rate (the first pumping rate in the first control parameter during the current first suction operation is the target pumping rate during the current first suction operation), a target pumping time (the target pumping time during the current first suction operation = (1 + the maximum value of the air pressure difference of all suction cups 918 during the previous first suction operation) × the first pumping time in the first control parameter during the current first suction operation);

[0158] The target conveying speed is determined based on the target control parameters of the suction cup 918 during each first suction operation and the detection value of the speed detection device before each first suction operation of the suction cup 918, specifically:

[0159] ;

[0160] The speed detection device of the suction cup 918 detects the value before the first suction operation; is the target conveying speed corresponding to the first suction operation of the suction cup 918; K is A corresponding target value (to ensure that the suction cup 918 can adsorb the next metal frame 13 in a timely manner, which can be determined based on testing); The distance between adjacent metal frames 13 along the conveying direction on the conveying mechanism 2 before the suction cup 918 performs the first material suction operation; The target air extraction time in the target control parameters of the suction cup 918 during the first suction operation;

[0161] The calculation module is based on the following formula:

[0162] ;

[0163] is the air pressure difference of the i-th suction cup 918 when the suction cup 918 is currently working for the first time; M is the total number of detections by the air pressure sensor when the suction cup 918 is working for the first time; The j-th detection value of the air pressure sensor in the i-th suction cup 918 when the suction cup 918 is in the first suction operation; It is the vertical coordinate corresponding to the j-th detection time of the air pressure sensor in the i-th suction cup 918 when the suction cup 918 is in the current first material suction operation in the standard value change curve of the suction cup 918 working time-the air pressure in the suction cup 918 under the target control parameters.

[0164] All the air pressure sensors in the suction cups 918 work synchronously each time;

[0165] The beneficial effects of the above technical solution are:

[0166] The system automatically adjusts target control parameters (target pumping rate and target pumping time) based on the real-time ambient temperature (the temperature outside the suction cup 918). This reduces the impact of temperature on vacuum adsorption performance and is particularly suitable for workshops with large temperature fluctuations (such as high temperatures in summer or low temperatures in winter).

[0167] Dynamically adjust the conveyor mechanism's conveying speed based on the target control parameters (e.g., pumping time) and the conveyor mechanism's real-time speed. If pumping time increases (e.g., due to temperature changes in pump efficiency and the required amount of air pumped into the suction cup 918), the system automatically reduces the conveyor mechanism's conveying speed to ensure the suction cup 918 has sufficient time to complete suction. This prevents suction failures caused by excessively fast cycles and reduces workpiece leakage or collisions caused by conveyor mechanism speed mismatches.

[0168] Accurately locate abnormal air pressure differences and quantitatively analyze each suction cup's built-in air pressure sensor. Real-time air pressure data is collected and compared with a standard value curve to calculate the air pressure difference. If the air pressure drop rate of a particular suction cup 918 is significantly slower than the standard curve, it may indicate a leak (such as a damaged seal) or poor adhesion to the workpiece surface. This system enables fault location at the individual suction cup level, avoiding the ambiguity of traditional "entire suction cup failure" alarms and shortening downtime for troubleshooting.

[0169] If the pressure difference exceeds the limit and the temperature detection value is higher than the reference value, first check whether the vacuum pump efficiency has decreased due to high temperature. If the temperature is normal but the difference is still high, it indicates a hardware failure of the suction cup (such as wear).

[0170] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
