The clamping device is used to clamp the workpiece to be coated using a hanger A. The transfer robot is used to transfer the hanger A and the workpiece to be coated clamped by the hanger A to the coating device as a whole. The coating device coats the workpiece to be coated clamped by the hanger A. It should be noted that the workpiece to be coated can be an FPC board, and of course it can also be other workpieces that need to be coated, which is not limited here. For ease of understanding, this article takes the FPC board as an example for explanation.

[0036] In an embodiment of the present application, the clamping device includes a carrying mechanism 10, a positioning mechanism 20, a clamping mechanism 30 and a conveying mechanism 40. The carrying mechanism 10 is used to carry a material box, in which a plurality of FPC boards are loaded. The conveying mechanism 40 is used to pick up the FPC board in the material box and transfer the picked up FPC board to the positioning mechanism 20. The positioning mechanism 20 positions the FPC board thereon. The clamping mechanism 30 is used to carry the hanger A, and the conveying mechanism 40 is also used to pick up the FPC board on the positioning mechanism 20 and transfer the picked up FPC board to the hanger A on the clamping mechanism 30, so as to clamp the FPC board using the hanger A. It should be noted that the conveying mechanism can adopt a conveying robot. Of course, other mechanisms with a conveying function can also be adopted in other embodiments, as long as the FPC board can be transferred between the carrying mechanism 10, the positioning mechanism 20 and the clamping mechanism 30, it is not limited here.

[0037] When the clamping device is actually used, first, the transport mechanism 40 picks up the FPC board in the material box on the carrier mechanism 10, and transfers the picked-up FPC board to the positioning mechanism 20; then, the positioning mechanism 20 is used to adjust the position of the FPC board on it, that is, to position the FPC board; then, the transport mechanism 40 picks up the FPC board on the positioning mechanism 20, and transfers the picked-up FPC board to the hanger A on the clamping mechanism 30, so that the hanger A clamps the FPC board. In this way, the clamping device of the present application can automatically complete the transfer, positioning and clamping of the FPC board without manual participation, which greatly improves the degree of automation and greatly reduces the risk of the FPC board falling or bumping.

[0038] In the embodiment of the present application, the clamping device further includes a receiving frame 50, the positioning mechanism 20, the clamping mechanism 30 and the conveying mechanism 40 are all arranged in the receiving frame 50, and the carrying mechanism 10 is arranged outside the receiving frame 50. The receiving frame 50 is provided with a feed port 51 on the side facing the carrying mechanism 10, and the feed port 51 is opposite to the opening of the material box on the carrying mechanism 10, so that the conveying mechanism 40 can grab the FPC board in the material box through the feed port 51. In this way, the carrying mechanism 10 is arranged outside the receiving frame 50, and the feed port 51 on the receiving frame 50 is used for the conveying mechanism 40 to pick up the FPC board in the material box, so as to facilitate loading the material box onto the carrying mechanism 10 or unloading the material box on the carrying mechanism 10.

[0039] Specifically in the embodiment, the clamping device further includes a switch cover mechanism 60, which includes a switch cover driving member 61 and a box cover 63. The switch cover driving member 61 is arranged in the receiving frame 50, and the box cover 63 is installed at the driving end of the switch cover driving member 61, so that the switch cover driving member 61 drives the box cover 63 to move to the closed position or the open position. When the box cover 63 is in the closed position, the box cover 63 covers the feed inlet 51 to close the feed inlet 51; when the box cover 63 is in the open position (see Figure 1 ) The box cover 63 opens the feed opening 51.

[0040] It should be noted that the cover opening and closing driving member 61 may adopt a linear driving module, such as a pneumatic cylinder or an electric cylinder, etc., as long as it can drive the box cover 63 to close or open the feed port 51, and is not limited here.

[0041] In some embodiments, the positioning mechanism 20 includes a positioning platform 21 and a visual detection component 22. The positioning platform 21 is used to carry the FPC board transferred by the transport mechanism 40. The visual detection component 22 is used to detect the position of the FPC board on the positioning platform 21, and the positioning platform 21 is also used to adjust the position of the FPC board according to the detection result of the visual detection component 22, so as to achieve the positioning of the FPC board. Optionally, the visual detection component 22 can use a CCD (Charge-coupled Device).

[0042] In some embodiments, the hanger A includes a first plate A1 and a second plate A2, and the clamping mechanism 30 includes a clamping base 31, a lifting suction cup 32 and a lifting drive 37. The clamping base 31 has a bearing position for bearing the first plate A1. The transport mechanism 40 is used to transport the FPC board on the positioning mechanism 20 to the first plate A1 located at the bearing position. The lifting suction cup 32 is located above the bearing position and is used to adsorb the second plate A2. The lifting drive 37 is connected to the lifting suction cup 32 to drive the lifting suction cup 32 to rise or fall, so that the second plate A2 follows the lifting suction cup 32 to rise and fall. When the lifting suction cup 32 descends, it can drive the second plate A2 to cover the first plate A1 located at the bearing position, thereby clamping the FPC board between the first plate A1 and the second plate A2. The first board A1 and / or the second board A2 has a hollow area, which is used to reveal the area of ​​the FPC board that needs to be coated. That is, the area of ​​the FPC board that needs to be coated is exposed by the hollow area on the first board A1 and / or the second board A2, and the area of ​​the FPC board that does not need to be coated is covered by the first board A1 and the second board A2.

[0043] In this way, when the conveying mechanism 40 transfers the FPC board to the first plate A1 located at the load-bearing position, first, the lifting drive 37 drives the lifting suction cup 32 to descend until the lifting suction cup 32 drives the second plate A2 to cover the first plate A1, so that the FPC board is clamped between the first plate A1 and the second plate A2; then, the lifting suction cup 32 stops adsorbing the second plate A2 and rises under the driving action of the lifting drive 37.

[0044] It should be noted that the lifting drive member 37 can adopt a linear module as long as it can drive the lifting suction cup 32 to move up and down, and there is no limitation here.

[0045] See also Figure 4Specifically, in the embodiment, the clamping mechanism 30 further includes a clamping assembly 33, which includes a moving rod 332, a pressing head 334 and a moving driving member 330. The moving driving member 330 is mounted on the clamping base 31, and the moving rod 332 is mounted on the driving end of the moving driving member 330. The pressing head 334 is mounted on the moving rod 332 to move with the moving rod 332. The moving driving member 330 is used to drive the moving rod 332 to move, so that the moving rod 332 drives the pressing head 334 to enter the upper space of the bearing position and press the second plate A2 on the first plate A1, ensuring that the first plate A1 and the second plate A2 press the FPC plate therebetween and ensuring that the sealing cavity (see below) therebetween is in a sealed state, or drives the pressing head 334 to separate from the second plate A2 and exit the upper space of the bearing position, ensuring that the pressing head 334 does not interfere with the subsequent unloading action of the transfer robot.

[0046] Optionally, the motion driving member 330 can realize driving the pressure head 334 to press or release the first plate A1 and the second plate A2 located on the bearing position by driving the motion rod 332 to perform lifting and rotational motion. It can be understood that the purpose of the motion rod 332 driving the pressure head 334 to rise is to separate the pressure head 334 from the second plate A2, the purpose of the motion rod 332 driving the pressure head 334 to descend is to make the pressure head 334 abut against the second plate A2, and the purpose of the motion rod 332 driving the pressure head 334 to rotate is to make the pressure head 334 enter or exit the upper space of the bearing position. The lifting and rotating motions of the motion rod can be performed simultaneously, or the rotational motion can be performed first and then the lifting and lowering motion, which is not limited here. It should be noted that the motion driving member 330 can be a cylinder, of course, other driving members can also be used, as long as the motion rod 332 can drive the pressure head 334 to perform lifting and lowering motion and rotational motion, which is not limited here.

[0047] Optionally, a plurality of pressing assemblies 33 are provided, and the plurality of pressing assemblies 33 are arranged at intervals around the bearing position. In this way, each pressing assembly 33 is used to simultaneously press the first plate A1 and the second plate A2, thereby ensuring a pressing effect.

[0048] Furthermore, when the second plate A2 is covered on the first plate A1, a sealed cavity is formed between the first plate A1 and the second plate A2. The clamping mechanism 30 further includes a sealing assembly 70 disposed on the clamping base 31, and the sealing assembly 70 is used to evacuate the sealed cavity between the first plate A1 and the second plate A2, so that the first plate A1 and the second plate A2 clamp the FPC board therebetween.

[0049] In actual use, first, the transport mechanism 40 transfers the FPC board in the material box to the positioning table 21; then, the visual detection component 22 detects the position of the FPC board on the positioning table 21, and the positioning table 21 adjusts the position of the FPC board according to the detection result of the visual detection component 22; then, the transport mechanism 40 transfers the FPC board on the positioning table 21 to the first plate A1 on the clamping base 31; then, the lifting drive component 37 drives the lifting suction cup 32 to descend until the lifting suction cup 32 drives the second plate A2 to cover the first plate A1; then, the pressure heads 334 of each clamping assembly 33 are pressed on the second plate A2, thereby The second plate A2 is pressed against the first plate A1, so that the sealed cavity between the first plate A1 and the second plate A2 is in a sealed state; then, the lifting suction cup 32 stops adsorbing the second plate A2, and the lifting drive 37 drives the lifting suction cup 32 to rise, so that the lifting suction cup 32 is separated from the second plate A2; then, the sealing component 70 evacuates the sealed cavity between the first plate A1 and the second plate A2, so that the first plate A1 and the second plate A2 clamp the FPC board therebetween under the negative pressure in the sealed cavity; then, the sealing component 70 stops evacuating, and the pressure heads 334 of each clamping component 33 rise and rotate to leave the space above the hanger A. Then, the transfer robot transfers the first plate A1, the second plate A2 and the FPC board clamped therebetween as a whole to the coating device, so that the coating device coats the FPC board between the first plate A1 and the second plate A2.

[0050] Specifically in the embodiment, the hanger A also includes a control valve 34 installed on the first plate A1, and the control valve 34 is connected to the sealed cavity between the first plate A1 and the second plate A2 through a pipeline. The sealing assembly 70 includes a trigger block 71 arranged on the clamping base 31, and the trigger block 71 has a circuit contact 73 and a gas circuit connector 74. The circuit contact 73 is electrically connected to an external power supply, and the gas circuit connector 74 is connected to an external negative pressure source. The trigger block 71 can be controlled to move to a conducting position or a disconnecting position relative to the clamping base 31. When the trigger block 71 moves to the conducting position, the circuit contact 73 is electrically connected to the control valve 34 on the first plate A1, and the gas circuit connector 74 is connected to the control valve 34 on the first plate A1. When the trigger block 71 moves to the disconnecting position, the circuit contact 73 is disconnected from the control valve 34 on the first plate A1, and the gas circuit connector 74 is disconnected from the control valve 34 on the first plate A1. Optionally, the control valve 34 can be a solenoid valve.

[0051] In this way, when it is necessary to evacuate the sealed cavity between the first plate A1 and the second plate A2, the control trigger block 71 is moved from the disconnected position to the conducting position relative to the clamping base 31, so that the circuit contact 73 is electrically connected to the control valve 34 on the first plate A1, and the gas circuit connector 74 is connected to the control valve 34 on the first plate A1. At this time, the control valve 34 is energized and in an open state, so that the external negative pressure source is connected to the sealed cavity through the gas circuit connector 74 and the control valve 34 in turn, and then the external negative pressure source evacuates the sealed cavity.

[0052] After the vacuuming is completed, the control trigger block 71 moves from the conducting position to the disconnecting position relative to the clamping base 31, so that the circuit contact 73 is disconnected from the control valve 34 on the first plate A1, and the gas circuit connector 74 is disconnected from the control valve 34 on the first plate A1. At this time, the control valve 34 loses power and is in a closed state, so that the sealed chamber is not connected to the outside world, ensuring that the sealed chamber maintains a vacuum.

[0053] Furthermore, the hanger A also includes a matching electric contact 35 and a matching gas connector 36 both mounted on the first plate A1, wherein the matching electric contact 35 is electrically connected to the control valve 34 through a wire, and the matching gas connector 36 is connected to the control valve 34 through a pipeline. When the trigger block 71 moves to the conduction position relative to the clamping base 31, the circuit contact 73 on the trigger block 71 is electrically connected to the matching electric contact 35 on the first plate A1, so that the external power source is electrically connected to the control valve 34 through the circuit contact 73, the matching electric contact 35 and the wire in sequence, so that the control valve 34 is powered and in a conduction state; at the same time, the gas circuit connector 74 on the trigger block 71 is connected to the matching gas connector 36 on the first plate A1, so that the external negative pressure source is connected to the control valve 34 through the gas circuit connector 74, the matching gas connector 36 and the pipeline in sequence, so that the external negative pressure source can evacuate the sealed cavity.

[0054] When the trigger block 71 moves to the disconnected position relative to the clamping base 31, the circuit contact 73 on the trigger block 71 is disconnected from the matching electrical contact 35 on the first plate A1, so that the control valve 34 loses power and is in a disconnected state, thereby maintaining the sealed chamber in a vacuum state; at the same time, the air circuit connector 74 on the trigger block 71 is disconnected from the matching air connector 36 on the first plate A1.

[0055] Furthermore, the sealing assembly 70 further includes a trigger driving member 72, which is fixedly mounted on the clamping base 31, and the trigger block 71 is connected to the driving end of the trigger driving member 72, so that the trigger driving member 72 can drive the trigger block 71 to move between the above-mentioned disconnection position and the conduction position. Optionally, the trigger driving member 72 can be a cylinder.

[0056] Please also see Figure 5 As shown, based on the above clamping device, the utility model also provides a clamping method, which includes the following steps:

Specifically, first, the positioning platform 21 receives the FPC board transferred by the transport mechanism 40, and the visual inspection component 22 detects the position of the FPC board on the positioning platform 21; then, the positioning platform 21 drives the FPC board thereon to adjust the position according to the detection result of the visual inspection component 22, until the FPC board on the positioning platform 21 reaches the preset position, that is, the positioning of the FPC board is completed.

Specifically, first, the first plate A1 and the second plate A2 of the hanger A are loaded onto the clamping base 31; then, the lifting drive 37 drives the lifting suction cup 32 to descend until the lifting suction cup 32 absorbs the second plate A2; then, the lifting drive 37 drives the lifting suction cup 32 to rise, so that the second plate A2 rises together with the lifting suction cup 32, at which time the first plate A1 and the second plate A2 are separated from each other and opened, so as to facilitate the subsequent loading of the FPC board onto the first plate A1. Of course, in other embodiments, the first plate A1 of the hanger A may be loaded onto the clamping base 31 first, and then the second plate A2 of the hanger A is loaded onto the lifting suction cup 32 in step S60, and then the lifting suction cup 32 drives the second plate A2 of the hanger A to descend to cover the first plate A1, as long as the first plate A1 and the second plate A2 of the hanger A can be clamped on the FPC board, it is not limited here.

[0063] Specifically, first, the lifting drive 37 drives the lifting suction cup 32 to descend until the lifting suction cup 32 drives the second plate A2 to cover the first plate A1, so that the FPC board is clamped between the first plate A1 and the second plate A2; then, the pressure head 334 of each clamping assembly 33 is used to press against the top surface of the second plate A2, thereby clamping the first plate A1, the second plate A2 and the FPC board between the first plate A1 and the second plate A2, so that the first plate A1 and the second plate A2 clamp the FPC board therebetween; then, the lifting suction cup 32 stops adsorbing the second plate A2, and the lifting drive 37 drives the lifting suction cup 32 to rise, so that the lifting suction cup 32 is separated from the second plate A2; then, the trigger drive 72 drives the trigger block 71 to move to the conduction position relative to the clamping base 31, so that the circuit contact 73 on the trigger block 71 is electrically connected to the matching electrical contact 35 on the first plate A1, and the air path connector 74 on the trigger block 71 is connected to the matching air contact 35 on the first plate A1.
