Description

Technical Field

[0001] The utility model relates to the technical field of suction cups, in particular to a flippable material-grabbing suction cup. Background Art

[0002] AOI (Automated Optical Inspection) technology is widely used in the electronics manufacturing industry to inspect the quality of various components, including FPCs. Due to their thinness, lightness, and flexibility, FPCs are widely used in a variety of fields, including mobile phones, tablets, and automotive electronics.

[0003] AOI can quickly and accurately detect various defects on FPC products, such as short circuits, open circuits, poor solder joints, missing or misaligned components, etc. Compared with manual visual inspection, AOI has higher detection accuracy and speed, and can complete the inspection of a large number of products in a short time, reducing errors caused by human factors, and improving production efficiency and product quality. When the AOI machine inspects the product, in order to facilitate the placement of the product, a robot with a handling suction cup is usually used to transfer the product to the inspection position and separate the product after the inspection is completed.

[0004] However, many FPC products are currently designed with double-sided structures, meaning that conductive circuits and components are laid out on both sides. Therefore, to ensure the overall performance and reliability of the product, both sides must be fully inspected. However, with existing technology, the product cannot be flipped over after one side is inspected, and manual flipping is still mainly done, allowing the AOI machine to inspect the other side of the product. However, manual flipping often cannot guarantee that the product is in the same position after flipping, resulting in poor consistency and prone to errors. In addition, manual flipping is inefficient and detrimental to product production.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a reversible material-grabbing suction cup, comprising:

[0013] As a further solution of the utility model: it also includes a frame, the first driving source is installed on the frame, the first driving source is driven and connected to a second transmission synchronous wheel, the screw transmission member is provided with a second rotating synchronous wheel, and a second synchronous belt is connected between the second transmission synchronous wheel and the second rotating synchronous wheel.

[0014] As a further solution of the present invention: the frame is further provided with a lifting linear guide rail, the tooling plate is provided with a slider, and the slider is slidably connected to the lifting linear guide rail.

[0015] As a further solution of the present invention: a rotary airtight bearing joint is provided between the secondary pipeline and the main pipeline.

[0019] Compared with the prior art, the beneficial effects of the present technical solution are as follows: after the inspection of one side of the product is completed, the flip suction cup is driven downward by the lifting and moving module to suck the product, and then the flip suction cup is driven upward to a flippable height by the lifting and moving module, and the first transmission synchronous wheel is rotated by the second driving source, and the first synchronous belt connected to the first transmission synchronous wheel drives the first rotating synchronous wheel to rotate, and the first rotating synchronous wheel is sleeved on the secondary pipe, so that the secondary pipe can drive the flip suction cup to flip, so that the product sucked by the flip suction cup is flipped to the top surface, and because the secondary pipe and the main pipe are rotatably connected, the main pipe will not be driven during the flipping process of the secondary pipe and the flip suction cup, so as to prevent the flip suction cup and the main pipe from generating a motion conflict during the flipping process, and then the robot of the inspection equipment controls the handling suction cup to place the product on the flip suction cup again on the inspection platform, so as to inspect the other side of the product, so as to solve the technical problem in the prior art that automatic flipping cannot be performed when facing products that require double-sided inspection, further reduce manual intervention, ensure the consistency of the inspection operation, and improve product inspection efficiency.

[0020] The secondary pipe and the main pipe are rotatably connected through a rotating airtight bearing joint, so that while maintaining the rotating connection, airtightness can be ensured to ensure that gas does not leak during the rotation of the secondary pipe, thereby ensuring the adsorption force of the flip suction cup. In addition, the rotatable design of the secondary pipe and the main pipe can also solve the problem of the air pipe in the traditional suction cup hindering the flipping action when the flip suction cup is flipped.

[0032] The flip suction cup 1 is provided with a secondary pipe 101, which is rotatably connected to the main pipe 102. The secondary pipe 101 is provided with multiple tracheal joints 103. The flip suction cup 1 also includes an upper plate 104, a middle frame 105 and a lower plate 106. The middle frame 105 has an inner cavity. The upper plate 104 is provided with multiple tracheal connecting blocks 107. The tracheal connecting blocks 107 are connected to the tracheal joints 103 through pipes, so that the trachea is connected to the inner cavity of the middle frame 105. The lower plate 106 has multiple suction holes 108 that communicate with the inner cavity of the middle frame 105. A mounting plate is provided on the upper plate 104, which is fixedly connected to the secondary pipe 101 through the mounting plate;

[0033] The main pipe 102 is connected to an externally installed blower. By starting the blower, a vacuum negative pressure is generated in the main pipe 102 and the secondary pipe 101. The multiple air pipe joints 103 provided on the secondary pipe 101 are connected to the multiple air pipe connection blocks 107 of the upper plate 104 through pipes. In addition, the middle frame 105 at the lower end of the upper plate 104 has an inner cavity, so that the inner cavity of the middle frame 105 generates a negative pressure, which in turn causes the multiple suction holes 108 provided on the lower plate 106 to generate suction, thereby achieving the function of adsorbing the product.

[0034] The lifting and moving module 2 includes a first driving source 201, a screw transmission member 202, and a lifting block 203 screwed to the screw transmission member 202. The first driving source 201 is used to drive the screw transmission member 202 to make the lifting block 203 move up and down;

[0035] By starting the first driving source 201, the screw transmission member 202 rotates clockwise or counterclockwise, so that the lifting block 203 screwed to the screw transmission member 202 can move up and down;

[0036] The tooling plate 3 is fixedly connected to the lifting block 203 , and a rotating bearing sleeve 301 is installed on the tooling plate 3 . The secondary pipe 101 passes through the rotating bearing sleeve 301 and is rotatably connected to the main pipe 102 .

[0037] The fixture plate 3 is fixedly connected to the lifting block 203, so that when the lifting module 2 is in operation, the lifting block 203 can drive the fixture plate 3 to move up and down. A rotating bearing sleeve 301 is provided on the fixture plate 3, and the secondary pipe 101 passes through the rotating bearing sleeve 301 and is then rotatably connected to the main pipe 102. When the fixture plate 3 is moved up and down, the secondary pipe 101 can drive the flip suction cup 1 to move up and down.

[0038] The flip drive module 4 includes a second drive source 401, a first transmission synchronous wheel 402, a first rotating synchronous wheel 403 and a first synchronous belt 404. The second drive source 401 drives the first transmission synchronous wheel 402, the first rotating synchronous wheel 403 is sleeved on the secondary pipeline 101, and the first synchronous belt 404 is sleeved between the first transmission synchronous wheel 402 and the first rotating synchronous wheel 403.

[0039] During the inspection of products (such as FPC boards), the product is sucked and placed on the inspection platform of the inspection equipment (such as an AOI machine) through the robot configured by the inspection equipment and the handling suction cup installed on the robot. The inspection equipment then inspects one side of the product. After the inspection is completed, the tooling plate 3 and the flip suction cup 1 are moved downward by starting the lifting and moving module 2. After the flip suction cup 1 contacts the product, the product is sucked. Then, the lifting and moving module 2 is used to move the flip suction cup 1 upward. When the flip suction cup 1 moves upward to a height that does not conflict with the inspection equipment during the flipping process, the second driving source 401 is started, and the second driving source 401 is used to rotate the first transmission synchronous wheel 402. The first transmission synchronous wheel 402 drives the first rotating synchronous wheel 403 through the sleeved first synchronous belt 404. The first rotating synchronous wheel is sleeved on the secondary pipe 101, so that the secondary pipe 101 can drive the flipping suction cup 1 to flip, so that the product sucked by the flipping suction cup 1 is flipped to the top surface, and because the secondary pipe 101 is rotatably connected to the main pipe 102, the main pipe 102 will not be driven during the flipping process of the secondary pipe 101 and the flipping suction cup 1, so as to prevent the flipping suction cup 1 and the main pipe 102 from having a movement conflict during the flipping process. Subsequently, the robot of the inspection equipment controls the transport suction cup to suck the product on the flipping suction cup 1 and put the product on the inspection platform again, so as to inspect the other side of the product, so as to solve the technical problem in the prior art that automatic flipping cannot be performed when facing products that need double-sided inspection, further reduce manual intervention, ensure the consistency of inspection operations, and improve product inspection efficiency;

[0040] Among them, in the technical solution of the present utility model, the flipping operation of the flip suction cup 1 is achieved by the second driving source 401 driving the first transmission synchronous wheel 402, and the first transmission synchronous wheel 402 drives the first rotating synchronous wheel 403 through the first synchronous belt 404, and the first rotating synchronous wheel 403 drives the secondary pipeline 101 when rotating. Through the above design, the second driving source 401 can be installed on a different horizontal line from the main pipeline 102 connected to the secondary pipeline 101, so that the second driving source 401 and the main pipeline 102 are staggered, so as to facilitate the assembly and layout of the equipment;

[0043] When the lifting and moving module 2 is in operation, the first driving source 201 is started, and the first driving source 201 is used to drive the second transmission synchronous wheel 204 to rotate. The second transmission synchronous wheel 204 drives the second rotating synchronous wheel 205 to rotate through the second synchronous belt 206, and then the second rotating synchronous wheel 205 is used to drive the screw transmission member 202 to rotate to realize the lifting and moving of the lifting block 203. Among them, the frame 5 is also formed with a limit path for the lifting block 203 to rise and fall, which can limit the moving direction of the lifting block 203 and prevent the lifting block 203 from driving the tooling plate 3 to rotate.

[0044] In this embodiment, please refer to Figure 4 It is further proposed that a lifting linear guide rail 501 is provided on the frame 5, and a slider 302 is provided on the tooling plate 3. The slider 302 is slidably connected with the lifting linear guide rail 501.

[0045] By arranging a lifting linear guide rail 501 on the frame 5 and arranging a slider 302 on the tooling plate 3 that can be connected to the slide of the lifting linear guide rail 501, it is possible to provide guided movement for the tooling plate 3 when the lifting block 203 drives the tooling plate 3 to move up and down. Among them, the lifting linear guide rails 501 and the slider 302 are both set in two numbers. The two lifting linear guide rails 501 are preferentially set at the two ends of the lifting block 203, and can also limit the rotation of the lifting block 203.

[0046] In this embodiment, please refer to Figure 3 It is further proposed that a rotating airtight bearing joint 6 is provided between the secondary pipe 101 and the main pipe 102; the secondary pipe 101 and the main pipe 102 are rotatably connected through the rotating airtight bearing joint 6, so that while maintaining the rotating connection, airtightness can also be ensured, ensuring that gas will not leak during the rotation of the secondary pipe 101, so as to ensure the adsorption force of the flip suction cup 1, and the rotatable design of the secondary pipe 101 and the main pipe 102 can also solve the problem that the air pipe in the traditional suction cup hinders the flipping action when the flip suction cup 1 is flipped.

[0048] The protective frame 405 can not only ensure that the second driving source 401 can be fixedly installed and moved up and down along with the tooling plate 3, but also protect the first transmission synchronous wheel 402 to reduce dust accumulation.

[0049] In this embodiment, please refer to Figure 2-3, it is further proposed that a pipe sleeve 7 is provided at one end of the protection frame 405, and the main pipe 102 is plugged into the pipe sleeve 7;

[0050] Then, a pipe sleeve 7 is provided on the protective frame 405 , and the main pipeline 102 is fixed by the pipe sleeve 7 to prevent the main pipeline 102 from being damaged.

The frame 5 is slidably connected to the slide rail. The driving motor drives the synchronous wheel to rotate, and the synchronous wheel engages with the rack. The rotational motion is converted into the linear motion of the rack, thereby driving the frame 5 to translate, and then driving the flip suction cup 1, so that the flip suction cup can be translated to a position away from the detection platform, which is convenient for the robot to control the handling suction cup to detect the product on the flip suction cup 1 and then place it on the detection platform.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
