[0017] This invention provides a high-precision rotary pick-up arm for a double-sided exposure machine. Compared with the prior art, it has the following advantages:

[0018] 1. This high-precision rotating material handling arm for double-sided exposure machines drives three suction cups to rise and fall synchronously when the rotating frame is raised and lowered. This allows the arm to grab the material to be exposed on one of the material trays, grab or place the exposed material on the tray, and place the exposed material on another material tray. In conjunction with the cyclical rotation of the rotating frame, the arm can place or grab the material in the three positions, thus eliminating the need for manual assistance in the entire process.

This high-precision rotating material handling arm for a double-sided exposure machine features a gas distribution ring that is fixedly connected to the top surface of the fixed frame via a fixed base when the vacuum adsorption process begins, ensuring its stable position during operation. The gas distribution ring itself is fixedly connected to the bottom surface of the rotating frame via a connecting frame, allowing it to rotate synchronously with the rotating frame. Subsequently, the three air inlet pipes at the bottom of the gas distribution ring begin operation. These three inlet pipes precisely correspond to the three inner cavities of the gas distribution ring and are each equipped with a solenoid valve. When a vacuum is required for the vacuum suction cup, an external air source is connected, the corresponding solenoid valve opens, and gas rapidly flows into the corresponding independent cavity of the gas distribution ring through the air inlet pipe. Due to the connection between the gas distribution ring and its inner cavity, the gas flows into the cavity of the gas distribution ring and is then transmitted to the vacuum suction cup via the connecting pipe, quickly creating a negative pressure environment inside the vacuum suction cup for stable adsorption of PCB materials. This structural design allows the vacuum suction cup to move freely and flexibly, unaffected by the air pipes, as it rotates with the rotating frame, performing material gripping actions at various angles.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0027] The utility model provides two technical schemes:

[0028] Figures 1-5 The first embodiment is shown: a high-precision rotary material taking arm for double-sided exposure machine, including double-sided exposure machine body 1, the upstream of double-sided exposure machine body 1 is equipped with taking mechanism, and the taking mechanism includes:

[0029] Rotary assembly 3 is used for feeding and discharging to double-sided exposure machine body 1, and rotary assembly 3 includes fixed frame 31 arranged on the upstream of double-sided exposure machine body 1, electric push rod 32 is installed in the top of fixed frame 31, the telescopic end of electric push rod 32 is slidably penetrated through the top of fixed frame 31 and extends upwards, lifting frame 33 is installed on the telescopic end of electric push rod 32, second motor 34 is installed in the bottom of lifting frame 33, the output shaft end of second motor 34 is movably penetrated through the top of lifting frame 33 and extends upwards, rotating frame 35 is installed on the output shaft end of second motor 34, three connecting rods 36 are installed on the bottom surface of rotating frame 35 close to the edge, and vacuum chuck 37 is installed on the bottom end of connecting rod 36;

[0030] Gas distribution assembly 4 is arranged on rotary assembly 3 and is used for vacuumizing vacuum chuck 37;

[0031] The material placing assemblies 5 are provided in two numbers, one of which is used to supply the material to be exposed to the rotating assembly 3, and the other of which is used to receive the material exposed by the rotating assembly 3.

[0032] The three vacuum suction cups 37 are fixed on top of the connecting pipes 38, and the three connecting pipes 38 are respectively communicated with the three inner cavities of the gas distribution ring 45.

[0033] The two material placing assemblies 5 each include a vertical seat 51, and a first motor 52 is mounted on top of the vertical seat 51. The output end of the first motor 52 is movably penetrated through the top of the vertical seat 51 and extends into the interior, and a lead screw 53 is mounted on the output end of the first motor 52. A lifting block 54 is threadedly sleeved on the outer wall of the lead screw 53, and the lifting block 54 is slidingly arranged in the interior of the vertical seat 51. A material placing disc 55 is fixedly connected to the outer surface of the lifting block 54.

[0034] The slide table 11 is mounted at the material inlet position of the double-sided exposure machine body 1, and extends to the outside of the double-sided exposure machine body 1 on one side and extends to the interior of the double-sided exposure machine body 1 on the other side. The gas cylinder 2 is mounted on the outer surface of the double-sided exposure machine body 1 on one side, and the telescopic end of the gas cylinder 2 is slidingly penetrated through the outer surface of the double-sided exposure machine body 1 and extends into the interior. The tray 21 is mounted on the telescopic end of the gas cylinder 2, and the tray 21 is slidingly arranged on the slide table 11.

[0035] The three vacuum suction cups 37 are respectively arranged above the tray 21 and the two material placing discs 55.

[0036] Specifically, the electric push rod 32 is started to push the rotating frame 35 to move upward, so that the material is slightly moved upward, and the subsequent rotating action is ensured not to be interfered. Then, the second motor 34 is started to drive the rotating frame 35 to rotate by 120 degrees, so that the material is moved to above the tray 21. Then, the electric push rod 32 is started again to drive the rotating frame 35 to move downward, so that the material is placed on the tray 21. Then, the gas cylinder 2 is started again to pull the material with the tray 21 into the interior of the double-sided exposure machine body 1 for exposure treatment.

[0037] After the exposure is completed, the gas cylinder 2 first sends out the tray 21, and the vacuum suction cups 37 of the rotating assembly 3 are moved to above the exposed material for adsorption. Then, the electric push rod 32 and the second motor 34 are cooperated to transfer the material to above the other material placing assembly 5 for receiving. The first motor 52 drives the material placing disc 55 to rise to a suitable height, and the vacuum suction cup 37 lowers the material, so that the circulation of the material from feeding to discharging is completed.

[0038] Figures 1-5The second embodiment is shown, and the main difference with the first embodiment is that the air distribution assembly 4 comprises an air distribution ring 41 wound outside the telescopic end of the electric push rod 32, and the air distribution ring 41 is arranged above the fixed frame 31 and below the lifting frame 33, the inside of the air distribution ring 41 is provided with three independent cavities, and the outer surface of the air distribution ring 41 is provided with an air distribution ring 45, the inside of the air distribution ring 45 is provided with three independent cavities, the inner cavity of the air distribution ring 45 is communicated with the inner cavity of the air distribution ring 41, and the air distribution ring 45 can rotate tightly on the surface of the air distribution ring 41;

[0039] A plurality of fixed seats 42 are mounted at the bottom of the air distribution ring 41, the bottom surface of the fixed seat 42 is fixedly connected with the top surface of the fixed frame 31, and a plurality of connecting frames 46 are mounted at the top of the air distribution ring 45, the top surface of the connecting frame 46 is fixedly connected with the bottom surface of the rotating frame 35.

[0040] Three air inlet pipes 43 are mounted at the bottom of the air distribution ring 41, the three air inlet pipes 43 are respectively communicated with the three inner cavities of the air distribution ring 41, and the air inlet pipe 43 is provided with an electromagnetic valve 44.

[0041] Specifically, when the system starts the vacuum suction process, the air distribution ring 41 is fixedly connected with the top surface of the fixed frame 31 through the fixed seat 42, so as to ensure that the position of the air distribution ring 41 is stable during operation. And the air distribution ring 45 is fixedly connected with the bottom surface of the rotating frame 35 through the connecting frame 46, so that the air distribution ring 45 can rotate synchronously with the rotating frame 35. Then, the three air inlet pipes 43 at the bottom of the air distribution ring 41 start to work. The three air inlet pipes 43 respectively correspond to the three inner cavities of the air distribution ring 41, and each is provided with an electromagnetic valve 44. When it is necessary to suck the vacuum chuck 37, the external gas source is connected, and the corresponding electromagnetic valve 44 is opened. The gas quickly flows into the corresponding independent cavity of the air distribution ring 41 along the air inlet pipe 43. Due to the communication between the air distribution ring 45 and the inner cavity of the air distribution ring 41, the gas immediately flows into the cavity of the air distribution ring 45, and then is transmitted to the vacuum chuck 37 through the connecting pipe 38, so that a negative pressure environment is quickly formed in the vacuum chuck 37, so as to realize the stable adsorption of the PCB material. This structure design makes the vacuum chuck 37 completely free from the restraint and influence of the air pipe during the rotation of the rotating frame 35, and freely and flexibly completes various angle material grabbing actions.

[0042] Meanwhile, the contents not described in detail in the specification all belong to the prior art known by those skilled in the art.

[0043] Working principle: when in use, a batch of PCB materials to be exposed can be stacked on the material placing disc 55 in one of the material placing assemblies 5, the first motor 52 is started to drive the screw rod 53 to rotate and drive the material placing disc 55 to rise until the material contacts the vacuum chuck 37 in the relative position and is adsorbed.

[0044] Afterwards, the electric push rod 32 is started to push the rotating frame 35 to move upwards, slightly moving the material upwards to ensure that the subsequent rotating action is not interfered, then the second motor 34 is started to drive the rotating frame 35 to rotate 120 degrees, moving the material to the upper side of the tray 21, then the electric push rod 32 is started again to drive the rotating frame 35 to move downwards, placing the material on the tray 21, then the cylinder 2 is started again to pull the material with the tray 21 into the double-sided exposure machine body 1 to perform exposure processing.

[0045] After the exposure is completed, the cylinder 2 sends out the tray 21, and the vacuum suction cup 37 repeats the adsorption process of the material after exposure and moves the material to the material placing plate 55 in another material placing assembly 5, and then places the material on the material placing plate 55, thereby completing the cycle of material from feeding to discharging.

[0046] When the rotating frame 35 is lifted, the three suction cups 37 are lifted synchronously, thereby respectively corresponding to grabbing the material to be exposed on one of the material placing plates 55, placing or grabbing the material on the tray 21, and placing the material on another material placing plate 55, cooperating with the rotating frame 35 to rotate cyclically, and placing or grabbing the material in three positions, thereby realizing the automation of the double-sided exposure machine feeding and discharging, ensuring the production continuity and efficiency.
