Description

Technical Field

[0001] The present invention relates to the technical field of planar material processing, and particularly relates to a double-sided detection and conveying device for planar materials and a UV printing device.

Background Art

[0002] In the field of planar material processing (such as the manufacturing industries of fan blades, plastic plates, metal plates, etc.), the surface quality inspection of products is a key link to ensure the qualified rate of finished products. For example, when printing patterns, dust-proof films, and protective films on the surface of fan blades by means of UV printing, it is necessary to detect in advance whether there are unevenness on the surface of the fan blades and whether there are defects on the edges.

[0003] Traditional inspection methods mainly rely on manual visual inspection. Operators need to observe and screen the front and back sides of the materials one by one. Since fan blades need to be inspected on both sides, manual inspection requires the fan blades to be flipped. On the one hand, the labor intensity of the staff is large. On the other hand, the inspection efficiency by the staff is low, and problems such as missed inspection are likely to occur, resulting in a decrease in the yield rate.

[0004] In view of the above technical problems, the present invention is specifically studied and proposed.

Detailed implementation manner

[0055] The following will describe the implementation manner of the present invention in detail with reference to the accompanying drawings.

[0056] As Figure 1-10 shown, a double-sided detection and conveying device for planar materials of the present invention includes a frame 1, a first detection mechanism 10, a flipping mechanism 3, an inductor 11, a second conveyor belt 12, a second detection mechanism 13, and a feeding mechanism 4.

[0057] Among them, two parallel and synchronously operating first conveyor belts 14 are provided on the frame 1. A loading area for planar materials is formed between the first conveyor belts 14 for synchronously conveying materials to be processed. The first detection mechanism 10 is arranged on the frame 1 on one side of the first conveyor belt 14 for detecting the surface quality of the front side of the materials. The flipping mechanism 3 is arranged on the frame 1 and between the rear parts of the two first conveyor belts 14 for flipping the materials by 180° after the front side detection and conveying them to the next process. As Figure 7As shown in the figure, the sensor 11 is installed on the frame 1 and is located between the rear parts of the two first conveyor belts 14 for detecting whether the material reaches the turning position of the turning mechanism 3. The second conveyor belt 12 is installed on the frame 1 and is located at the rear end of the first conveyor belt 14 for receiving and conveying the turned-over material. The second detection mechanism 13 is installed above the second conveyor belt 12 for detecting the surface quality of the reverse side of the material with a qualified front side. The feeding mechanism 4 is installed on the side of the frame 1 for conveying the material that passes both-sided detection to the next process and transferring the unqualified material to the waste area. The feeding mechanism 4 includes a linear module 40 and a third conveyor belt 41. The third conveyor belt 41 is installed on the sliding table of the linear module 40 and is driven by the linear module 40 to dock with the end of the second conveyor belt 12 or with the next process.

[0058] As Figure 4 shown in the figure, the sensor 11 can also be installed above the turning position of the turning mechanism 3. By setting a fixed rod on the frame 1, the top of the fixed rod extends above the turning position, and then the sensor 11 is set on the fixed rod to detect whether the material reaches the turning position.

[0059] In this embodiment, the material can be a fan blade, sheet wood, plastic board, etc. Here, a fan blade is taken as an example. During the detection, the fan blade is placed on the input end of the first conveyor belt 14 manually or by mechanical equipment. Since there are two first conveyor belts 14, the fan blade is placed on the two first conveyor belts 14. The two first conveyor belts 14 synchronously convey the fan blade forward. During the conveying process, the fan blade will pass through the first detection mechanism 10. The first detection mechanism 10 identifies whether the front side of the fan blade meets the standard, such as whether there are uneven surfaces or incomplete edges. After the detection is completed, a signal is sent to the controller (not shown in this application) of the present application to record whether the fan blade is qualified. Then the first conveyor belt 14 continues to convey the fan blade forward. After the sensor 11 detects the fan blade, the turning mechanism 3 adsorbs the fan blade, turns it over, and conveys it to the second conveyor belt 12. If the fan blade is an unqualified product, the second conveyor belt 12 directly conveys the fan blade to the third conveyor belt 41, and the third conveyor belt 41 directly conveys the fan blade to the waste area. If the front side of the fan blade is detected as qualified, the second detection mechanism 13 continues to detect whether the reverse side of the fan blade is qualified. If it is qualified, it is conveyed to the third conveyor belt 41, and then the linear module 40 drives the third conveyor belt 41 to move, and the third conveyor belt 41 conveys the blade to the next process. Similarly, if the reverse side of the fan blade is also unqualified, the third conveyor belt 41 conveys the fan blade to the waste area. In addition, it should be noted that the third conveyor belt 41 can rotate forward and backward. When conveying unqualified fan blades, it can directly convey the fan blades backward to the waste area.

[0060] In this embodiment, the first detection mechanism 10 and the second detection mechanism 13 can collect data on the fan blades by image recognition to determine whether the surface of the fan blades meets the standards, such as by collecting through a CCD camera. The controller can be a PLC controller, which can be arranged in the frame 1. The method of linkage and cooperation with the sensor 11 is a conventional technology and will not be repeated in this application.

[0061] As can be seen from the above, the present application can detect the front and back of the fan blades, and can remove unqualified products. Compared with the previous manual inspection method, it can be faster and more efficient, reduce the labor intensity of the staff, and improve production efficiency. In addition, compared with manual screening, the accuracy can be higher, preventing defective products from flowing into the next process.

[0062] like Figures 5 to 10 As shown, as a further solution of this embodiment, the turning mechanism 3 includes a turning assembly 30, a receiving plate 5 and a pushing assembly 6. Among them, the turning assembly 30 is arranged on the frame 1 and located between the rear parts of the two first conveyor belts 14, and is used to turn the material 180° after the front detection is completed. The receiving plate 5 is mounted on the rear ends of the two first conveyor belts 14, and is used to receive the turned material. The pushing assembly 6 is arranged on the receiving plate 5, and is used to push the turned material to the second conveyor belt 12.

[0063] The flipping assembly 30 includes a support frame 31, a rotating shaft 32, a driving motor 33, a vacuum suction cup 34 and a connecting piece 35, wherein a pair of support frames 31 are provided and are arranged on the frame 1 at intervals and are located in the area between the two first conveyor belts 14, the rotating shaft 32 is arranged between the support frames 31 and rotates with the corresponding support frame 31, the driving motor 33 is arranged on one of the support frames 31, and the output shaft of the driving motor 33 is connected to the rotating shaft 32 to drive the rotating shaft 32 to rotate; the vacuum suction cup 34 is used to absorb the material after inspection, one end of the connecting piece 35 is fixedly connected to the rotating shaft 32, and the other end is connected to the vacuum suction cup 34, which is used to drive the vacuum suction cup 34 to rotate around the rotating shaft 32, so as to flip the material and move it to the receiving plate 5, wherein the receiving plate 5 is provided with an avoidance opening for avoiding the connecting piece 35 and the vacuum suction cup 34. When flipping, the driving motor 33 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the connecting member 35 to rotate, and the connecting member 35 drives the vacuum suction cup 34 to adsorb the front of the fan blade. After adsorbing the fan blade, the driving motor 33 drives the rotating shaft 32 to rotate in the opposite direction, so as to transport the fan blade to the receiving plate 5. Since, after flipping, the vacuum suction cup 34 is located at the bottom of the fan blade, an avoidance opening is provided on the receiving plate 5 for avoiding the connecting member 35 and the vacuum suction cup 34.

[0064] like Figure 7As shown in the figure, as a further solution of this embodiment, the pusher assembly 6 includes a left pusher block 60 disposed at the left end of the receiving plate 5 and a right pusher block 61 disposed at the right end of the receiving plate 5. The pusher assembly 6 further includes a left air cylinder 62 and a right air cylinder 63 that operate synchronously. The piston rod of the left air cylinder 62 is connected to the left pusher block 60, and the piston rod of the right air cylinder 63 is connected to the right pusher block 61. After the flipping assembly 30 flips the fan blade onto the receiving plate 5, the pusher assembly 6 pushes the fan blade onto the second conveyor belt 12. The specific operation is as follows: After the fan blade is placed on the receiving plate 5, the left air cylinder 62 and the right air cylinder 63 are started simultaneously, thereby driving the left pusher block 60 and the right pusher block 61 to push the fan blade at the same time, and then pushing the fan blade onto the second conveyor belt 12. In addition, the shapes of the left pusher block 60 and the right pusher block 61 can be adjusted according to the actual product to adapt to the shape of the product. For example, in this embodiment, the left pusher block 60 can be provided with an arc-shaped groove to adapt to the arc-shaped end of the fan blade, and the right pusher block 61 also correspondingly matches the shape of the right end of the fan blade, so that the process of pushing the fan blade can be smoother. In addition, the left air cylinder 62 and the right air cylinder 63 can be installed on the first conveyor belt 14 or on the receiving plate 5.

[0065] As Figure 9 , Figure 10 shown in the figure, as a further solution of this embodiment, the connecting member 35 includes an arc-shaped connecting rod 350 and a linear connecting rod 351 connected to one end thereof. One end of the linear connecting rod 351 is fixedly connected to the rotating shaft 32, and one end of the arc-shaped connecting rod 350 is rotatably connected to the vacuum suction cup 34. An elastic reset member 7 is further provided between the vacuum suction cup 34 and the arc-shaped connecting rod 350 for enabling the vacuum suction cup 34 to be reset to the initial position after being stressed and rotated. For the convenience of flipping, in this embodiment, the radian of the arc-shaped connecting rod 350 is set between 80° and 100°, preferably 90°. When the vacuum suction cup 34 just sucks the fan blade, the fan blade forms a 90° angle with the linear connecting rod 351 at this time. The vacuum suction cup 34 is exactly parallel to the fan blade, so that the fan blade can be adsorbed more firmly. And making the vacuum suction cup 34 and the arc-shaped connecting rod 350 rotatably connected and providing the elastic reset member 7 is because when releasing the fan blade onto the receiving plate 5, due to the certain thickness of the fan blade, or because the receiving plate 5 is higher than the conveying plane of the first conveyor belt 14 and the reason of assembly error, after the fan blade is flipped 180°, it is difficult for the fan blade to be exactly parallel to the plane of the bearing plate. After the elastic reset member 7 is provided, even if the fan blade is flipped 180°, although the fan blade cannot be parallel to the receiving plate 5, when the fan blade contacts the receiving plate 5, it can drive the vacuum suction cup 34 to rotate on the arc-shaped connecting rod 350, and then the fan blade can be parallel to the receiving plate 5, which is convenient for placing the fan blade on the receiving plate 5. In addition, it should be noted that in order to prevent the fan blade from being scratched when contacting the receiving plate 5, a silica gel pad (not shown in the figure) can be provided in the area where the plug-in plate 5 contacts the fan blade.

[0066] AsFigure 9 , Figure 10 As shown, as a further solution of this embodiment, a rotating block 36 is formed on the vacuum suction cup 34. A rotating groove 37 that rotates in cooperation with the rotating block 36 is formed at the end of the arc-shaped connecting rod 350. A connecting hole 38 penetrating through the rotating groove 37 is provided at the end of the arc-shaped connecting rod 350. A connecting shaft 39 is provided in the connecting hole 38, and the rotating block 36 rotates in cooperation with the connecting shaft 39. The elastic resetting member 7 includes two torsion springs 70 respectively located on both sides of the rotating block 36 and two locking blocks 71 respectively corresponding to the torsion springs 70. Both the torsion springs 70 and the locking blocks 71 are sleeved on the shaft. One end of the torsion spring 70 is clamped with the rotating block 36, and the other end of the torsion spring 70 is clamped with the locking block 71. The locking block 71 is fixedly arranged at the connecting hole 38. In this embodiment, a threaded section (not shown in the figure) can be formed at the front end of the connecting shaft 39, and a nut that is threadedly matched with it is provided. The rear end of the connecting shaft 39 can be set as a hexagonal head, and a hexagonal hole is correspondingly provided on one side of the arc-shaped connecting rod 350. In this way, the connecting shaft 39 can be locked after passing through the connecting hole 38. When installing the torsion spring 70 and the locking block 71, first install the torsion spring 70 into the connecting hole 38, then turn the locking block 71 into the connecting hole 38, and finally align the rotating block 36 on the vacuum suction cup 34 with the rotating groove 37, and then insert the connecting shaft 39 to lock it. In order to prevent the locking block 71 from rotating, a rotation stopping portion 72 that cooperates with the connecting hole 38 to limit the rotation of the locking block 71 is provided on the locking block 71. By providing the torsion spring 70 and the locking block 71, after the vacuum suction cup 34 rotates on the connecting shaft 39 through the rotating block 36, since the locking block 71 is fixedly arranged in the connecting hole 38 and the torsion spring 70 is also clamped with the locking block 71 and the rotating block 36, it will drive the rotating block 36 to reset, thereby resetting the vacuum suction cup 34.

[0067] As Figures 1 to 3 shown, the present application also provides a UV printing device, which includes the above-mentioned planar material double-sided detection and conveying device, and also includes a fourth conveyor belt 8 that cooperates with the third conveyor belt 41 to receive the materials conveyed by the third conveyor belt 41 and a UV printer 80 arranged on the fourth conveyor belt 8. The UV printer 80 can print on planar products, such as printing patterns, protective films, dust-proof films, etc. on the fan blades. Before printing, a white primer is generally applied to the fan blades first to better display the printed color. If there are problems such as damage to the primer sprayed on the fan blades, or the surface is uneven or scratched, it will affect the final product.

[0068] The UV printing device of the present application, by adopting the above-mentioned planar material double-sided detection and conveying device, can detect the fan blades to screen out unqualified fan blades, such as problems like scratches on the surface of the fan blades or damage to the primer, to prevent unqualified fan blades from affecting the printing quality.

[0069] A transition and temporary storage mechanism 9 is further provided between the fourth conveyor belt 8 and the third conveyor belt 41. The transition and temporary storage mechanism 9 includes a fifth conveyor belt 90, a guide frame 91 and a driving assembly 92. The feeding end of the fifth conveyor belt 90 is connected to the feeding mechanism 4, and the discharging end is connected to the fourth conveyor belt 8. The driving assembly 92 is arranged above the conveyor belt and used to drive the guide frame 91 to move up and down. The guide frame 91 includes a plurality of guide bars 910 arranged at intervals and a connecting plate 911 connecting the plurality of guide bars 910. A guide channel 912 is formed between adjacent guide bars 910. A limiting rod 913 is provided at the end of the guide channel 912. The connecting plate 911 is connected to the driving assembly 92. The feeding mechanism 4 conveys the materials to be printed into the guide channel 912 in sequence on one side. In this application, after the transition and temporary storage mechanism 9 is provided, when the UV printing device is working, the feeding mechanism 4 conveys the fan blades into the guide channel 912 one by one for arrangement. After the arrangement is full, at this time, when the UV printing device is working, the previous batch of fan blades will be printed. Subsequently, the driving assembly 92 drives the guide frame 91 to rise, releasing the restriction on the fan blades, and the fan blades can be conveyed to the fourth conveyor belt 8 in the printing device by the fifth conveyor belt 90. The driving assembly 92 includes a gantry 920 arranged on the fifth conveyor belt 90 and a lifting cylinder 921 arranged on the gantry 920. The connecting plate 911 is connected to the piston rod of the lifting cylinder 921. In addition, a plurality of guide rods (not marked in the figure) that are slidably matched with the gantry 920 are provided on the connecting plate 911. In addition, when the guide frame 91 limits the fan blades, its bottom does not contact the fifth conveyor belt 90.
