[0002] During the PCB processing, the stacked boards need to be picked up and placed on the processing platform. As the number of boards picked up decreases, the thickness of the stack becomes thinner and thinner. The current picking mechanism relies on the cylinder to move a fixed distance, and the suction cup's spring compression touches the material to absorb it, which greatly limits the thickness of the stacked material and easily crushes the material during the picking process.

[0018] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0019] like Figure 1-2As shown, the present application discloses an automatic height-detecting and material-taking mechanism, comprising a crossbeam 1, wherein the crossbeam 1 is connected to a mounting bearing plate 2 through an angle code, and a mounting seat 3 is arranged on the mounting bearing plate 2. The characteristic is that a motor 4 is arranged on the mounting seat 3, and the motor 4 is connected to a vertically extending screw rod 6 through a coupling 5, and the screw rod 6 cooperates with a magnetic suction cup plate 7 and drives the magnetic suction cup plate 7 to rise and fall, and a magnetic base vacuum suction cup 9 and a height-detecting structure 11 are arranged under the magnetic suction cup plate 7, and the height-detecting structure 11 is used to detect the distance between the magnetic base vacuum suction cup 9 and the PCB board to be sucked, and the height-detecting structure 1 comprises a height-detecting seat 13 installed under the magnetic suction cup plate 7, and a height-detecting mounting sleeve 14 is arranged on the height-detecting seat 13, and a height-detecting connecting rod 15 is sleeved in the height-detecting mounting sleeve 14, and the height-detecting connecting rod 15 is sleeved in the height-detecting connecting rod 15. The lower end is a high-pressure probe head 17, and a high-pressure probe head 17 is provided with a high-pressure probe spring 16 between the high-pressure probe head 17 and the high-pressure probe mounting sleeve 14. A photoelectric sensor is provided in the high-pressure probe seat 13 for detecting the high position of the high-pressure probe connecting rod. The magnetic base vacuum suction cup 9 includes a magnetic base and a vacuum suction cup. The magnetic base is magnetically connected to the magnet suction cup plate 7 and can be installed at any position of the magnet suction cup plate 7. A lifting guide frame 8 is provided on the magnet suction cup plate 7, and the column of the guide lifting frame 8 passes through the mounting bearing plate 2. A vacuum control switch assembly 10 is provided on the magnet suction cup plate 7. The vacuum switch control assembly 10 is connected to the magnetic base vacuum suction cup 9 one by one through a flexible soft air pipe, and the vacuum switch control assembly 8 is connected to the solenoid valve and the vacuum generator to provide the suction opening and closing switching for it.

[0020] When in use, the sheets to be processed are stacked and placed under the magnetic base vacuum suction cup 9, the vacuum control switch assembly 8 turns on the magnetic base vacuum suction cup 9 corresponding to the corresponding position, the motor 4 runs to drive the screw rod 6, the screw rod 6 drives the lower magnetic suction cup plate 7 to move downward, the magnetic base vacuum suction cup 9 and the high-pressure probe head 17 descend together, the high-pressure probe head 17 will first contact the sheet and compress the height-probing spring 16, which will cause the height-probing connecting rod 15 to rise relative to the height-probing seat 13 until the magnetic base vacuum suction cup 9 completes the absorption of the sheet. At this time, the height-probing connecting rod 15 will be in a high position and will be sensed by the photoelectric sensor to generate a feedback signal. The feedback signal is fed back to the motor 4 to stop it and reverse, driving the screw rod 6. The screw rod 6 drives the magnetic suction cup plate 7 to move upward, and the magnetic base vacuum suction cup 9 absorbs the highest-position material together upward to complete the absorption of the highest-position material. During the absorption process, the magnetic base vacuum suction cup 9 can control the downward pressure of the sheet to avoid the sheet from being crushed.

[0021] During the specific implementation of the present invention, there will usually be a processing platform carrying the taken materials for processing. The processing platform will move under the magnetic base vacuum suction cup 9, and the motor 4 will drive the sucked materials to move downward and place them on the processing platform. The motor 4 will run to the initial position, the platform will move away, and the stacked sheets will return to the bottom of the magnetic base vacuum suction cup 9 again, and the material at the highest position of the stacked sheets will be sucked cyclically.

[0022] The utility model can improve the adaptability to sheets and plates of various sizes through the optimized structure. Through the cooperative movement of the screw motor assembly and the lifting guide frame and the operation of the height detection assembly, the current thickness of the stacked material can be automatically identified to ensure that the compression amount of the suction cup for each plate is the same, and light pressure is used to absorb, ensuring that the product is not crushed, and increasing the initial stacking thickness of the material, reducing the material change time, and improving the material picking stability and the production efficiency of the machine.

[0023] Holes 12 are arranged in an array on the magnetic suction cup plate 7. For some heavy plates, the magnetic vacuum suction cup 9 can also be installed under the hole 12, and the magnetic vacuum suction cup 9 can be reinforced by structures such as bolts passing through the tube to further ensure stability.
