Description

Technical Field

[0001] The utility model relates to the field of circuit board transmission, in particular to an anti-stacked board detection device. Background Art

[0002] During the circuit board processing process, it is necessary to go through the product information processing link. The product information processing link usually uses an automatic loading device for transmission. Most of the existing automatic loading devices use vacuum suction nozzles to adsorb the circuit boards to the conveyor belt. The circuit boards have electrostatic attraction to each other. The vacuum suction nozzle will adsorb multiple circuit boards to the conveyor belt at one time, which is easy to cause stacking of boards. Stacking will directly cause the upper surface product information in the subsequent product information processing to be processed to the back circuit board, resulting in direct scrapping of the circuit board. In the existing patent CN221853224U, a pressure roller and a sensor are used to detect the height of the PCB board to determine whether the PCB board is stacked. However, the pressure roller pressing over the upper surface of the circuit board is likely to cause damage to the circuit board, increasing the scrap rate of the circuit board.

[0024] In order to further understand the content, features and effects of the utility model of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] See also Figures 1 to 5, provides an anti-overlapping plate detection device, including a control component, a main frame 1 and a transmission component 3, the main frame 1 is provided with a transmission channel, the transmission component 3 is fixed to the transmission channel, the transmission component 3 is connected to the control component, the main frame 1 is provided with a detection component 4 above the transmission component 3, the detection component 4 is connected to the control component, the detection component 4 includes a lifting drive mechanism 41 and an electronic micrometer 42, the electronic micrometer 42 is fixed to the lifting end 411 of the lifting drive mechanism 41, and the detection end 421 of the electronic micrometer 42 faces the transmission surface 311 of the transmission component 3. When a circuit board is placed on the transmission assembly 3, the transmission assembly 3 transports the circuit board, and the control assembly controls the detection assembly 4 to detect the height of the circuit board on the transmission assembly 3. Specifically, the lifting drive mechanism 41 controls the detection end 421 of the electronic micrometer 42 to rise and fall, detecting the height of each passing circuit board. Since the height of each circuit board of the same model is equal, if the height of one circuit board is detected to be abnormal, the control assembly will control the transmission assembly 3 to stop operation, preventing the circuit board with abnormal height from flowing into the subsequent processing link, effectively preventing the stacked boards from being scrapped. Specifically, the lifting drive mechanism 41 can be a cylinder.

[0026] Specifically, the transmission assembly 3 includes a rotary driver 32, a transmission belt 33, and several transmission shafts 31. One end of the transmission belt 33 is drivingly connected to the output end of the rotary driver 32, and the other end of the transmission belt 33 is drivingly connected to one end of all the transmission shafts 31. The rotary driver 32 is mounted on the bottom of the main frame 1. The upper surfaces of the transmission shafts 31 form a transmission surface 311. The rotary driver 32 drives the transmission belt 33 to rotate, and all the transmission shafts 31 are connected to the transmission belt 33. The rotary driver 32 is connected to a control assembly. Therefore, when a circuit board is placed on the transmission surface 311, the control assembly can be controlled to activate the rotary driver 32, causing all the transmission shafts 31 to rotate synchronously to transport the circuit board. Specifically, the rotary driver 32 can be a motor.

[0027] More specifically, the main frame 1 includes a first baffle 5 and a second baffle 7, which are respectively mounted on the main frame 1. The ends of the transmission shaft 31 are rotatably connected to the first baffle 5 and the second baffle 7. A first connection hole 52 and a fourth connection hole 71 are respectively provided on the corresponding side walls of the first baffle 5 and the second baffle 7. The ends of the transmission shaft 31 are rotatably connected to the first connection hole 52 and the fourth connection hole 71, respectively. The bottom wall of the first baffle 5 is provided with a second connection hole 53. The main frame 1 is provided with bolts corresponding to the second connection hole 53. The bolts pass through the second connection hole 53 to secure the main frame 1. Multiple transmission shafts 31 are evenly fixed between the first baffle 5 and the second baffle 7, thereby improving the connection stability of the transmission shafts 31.

[0028] More specifically, a lower pressing plate 6 is fixed to the upper end of the first baffle 5, one end of the lower pressing plate 6 is located above one end of the transmission shaft 31 and is spaced apart from the transmission shaft 31, and the other end of the lower pressing plate 6 is provided with a third connecting hole 61, and the main frame 1 is provided with a bolt corresponding to the third connecting hole 61, and the bolt is fixed to the main frame 1 through the third connecting hole 61, and a first mounting groove 51 is formed between the first baffle 5 and the lower pressing plate 6, and one end of the transmission shaft 31 is located in the first mounting groove 51, and a gap is left between the lower pressing plate 6 and the upper surface of all the transmission shafts 31 for circuit board transmission. In actual applications, when circuit boards are stacked, it is generally the case that two or three circuit boards are stacked. In order to avoid collision between two or three overlapping circuit boards and the lower pressing plate 6, To protect the circuit boards, the size of the gap can be set to be greater than the sum of the thicknesses of three circuit boards and less than the sum of the thicknesses of four circuit boards, so that two or three circuit board stacks can be normally transported to the detection position by the transmission shaft 31. The detection component 4 then detects the stacking of the circuit boards to determine the stacking. Of course, there are special cases where four or more circuit boards are stacked. However, due to the heavy weight of the four or more circuit board stacks, the transmission shaft 31 cannot transport these four or more circuit boards, so that the four or more circuit boards are blocked outside the lower pressure plate 6. When the detection component 4 cannot detect the circuit boards, it proves that there is a stacking problem, and the operator or external equipment can remove the four or more circuit boards. When the circuit board is transported on the surface of the transmission shaft 31, one side of the circuit board is embedded in the gap between the lower pressure plate 6 and the transmission shaft 31. The lower pressure plate 6 does not contact the upper surface of the circuit board. When the transmission component 3 jams and causes the circuit board to shake up and down, the lower pressure plate 6 can effectively prevent the circuit board from moving due to transportation bumps.

[0029] Because it is necessary to avoid the circuit board from colliding with the lower pressure plate 6 when passing through the gap, and at the same time, the lower pressure plate 6 must also satisfy the limiting effect of the circuit board. Therefore, according to the record analysis of the stacking phenomenon, the number of circuit boards in one stacking is usually less than three. Therefore, it is best to set the gap between the lower pressure plate 6 and the upper surface of the transmission shaft 31 to a maximum size that can allow three circuit boards to overlap and pass through.

[0030] More specifically, a third mounting slot 74 is defined at the lower end of the second baffle 7. The other end of the transmission shaft 31 is positioned within the third mounting slot 74, and the transmission belt 33, which is wound around the transmission shaft 31, is positioned within the third mounting slot 74. Specifically, a pulley is mounted at the end of the transmission shaft 31, and the transmission belt 33 drives the transmission shaft 31 via the pulley. The transmission belt 33 is threaded through the third mounting slot 74, and the rotation driver 32 is positioned below the third mounting slot 74. Partitions are located on both sides of the third mounting slot 74 to prevent circuit boards from becoming entangled in the transmission belt 33. The third mounting slot 74 also serves to protect the transmission belt 33.

[0031] More specifically, the second baffle 7 is equipped with a protruding plate 72, which is located above the other end of the transmission shaft 31 and spaced apart. A clearance is left between the protruding plate 72 and the upper surface of all transmission shafts 31 for circuit board transmission. The clearance between the protruding plate and the transmission shaft is equal to the clearance between the lower pressure plate and the transmission shaft. A second mounting groove 73 is formed between the protruding plate 72 and the second baffle 7. When the circuit board is transported on the surface of the transmission shaft 31, the other side of the circuit board is embedded in the gap between the protruding plate 72 and the transmission shaft 31.

[0032] Specifically, a support plate 2 is provided on the top of the main frame 1, and the main body of the lifting drive mechanism 41 is fixed to the support plate 2. The lifting drive mechanism 41 is located above the transmission shaft 31. During detection, the lifting drive mechanism 41 controls the electronic dial indicator 42 to rise and fall.

[0033] Specifically, a plurality of support columns are provided at the bottom of the main frame 1 to keep the main frame 1 away from the ground. Space is left between each support column to accommodate the rotation driver 32, which keeps the transmission component 3 away from the ground, facilitates operation and protects the transmission component 3.

[0034] When in use, the circuit boards are placed on the transmission shaft 31 in sequence, and the control component controls the rotation driver 32 to start and drives the transmission shaft 31 to rotate through the transmission belt 33. The rotating transmission shaft 31 transports the circuit boards, and the lifting drive mechanism 41 drives the electronic micrometer 42 to lift and lower so that the electronic micrometer 42 is in the detection position and performs height detection on each circuit board passing through. If there are more than three circuit boards stacked together, since the gap between the lower pressure plate 6 and the transmission shaft 31 and the gap between the convex plate 72 and the transmission shaft 31 can only allow three circuit boards to overlap and pass through, more than three circuit boards cannot pass through the gap, and no circuit board on the transmission shaft 31 passes through the electronic micrometer 4. 2, the electronic micrometer 42 detects a height abnormality, and the control component controls the rotating driver 32 to stop running. If only two or three circuit boards are stacked together, passing through the gap and transported by the transmission shaft 31, the electronic micrometer 42 can detect the height of the circuit boards and determine whether there is a problem of overlapping circuit boards. When the height value detected by the electronic micrometer 42 is greater than the height value of a circuit board, it proves that overlapping circuit boards have occurred, and the information is transmitted to the control component. The control component controls the rotating driver 32 to stop running to prevent the overlapping circuit boards from flowing into the next program and causing further losses. Since the electronic micrometer 42 only lightly touches the upper surface of the circuit board each time it is detected, it will not cause damage to the circuit board.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
