Description

Technical Field

[0001] This utility model belongs to the field of printing monitoring technology, specifically a device for monitoring the printing quality of patterns on the surface of spheres. Background Technology

[0002] Surface printing on spheres refers to printing patterns onto the surface of spherical workpieces using methods such as film printing, transfer printing, and special printing techniques, thereby creating finished workpieces with decorative patterns.

[0003] After the pattern is printed on the sphere, it is usually necessary to monitor the quality of the printed pattern in order to identify defective workpieces and reduce the defect rate. When monitoring the workpiece, a camera is usually used to capture the pattern, and then the data is transmitted to a computer for analysis and comparison to check whether the printing quality is up to standard. In long-term use and observation, it was found that when capturing images of spherical workpieces, the special shape of the sphere requires the sphere to be rotated in order to capture the sphere comprehensively. However, the existing method usually uses manual rotation, which causes the sphere to easily shift at an angle during rotation, affecting the image acquisition position and accuracy.

[0004] Therefore, this utility model provides a device for monitoring the printing quality of patterns on the surface of spheres. Summary of the Invention

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, the ball surface pattern printing quality monitoring device includes an operating table 1; multiple side plates 11 are fixedly connected to the top of the operating table 1; the multiple side plates 11 are arranged in a circumferential array structure; a first cylinder 12 is fixedly connected to the side wall of the side plate 11; a fixing block 13 is fixedly connected to the end of the first cylinder 12; a rotating shaft 14 is rotatably connected to the side wall of the fixing block 13; a top plate 15 is fixedly connected to the end of the rotating shaft 14; a first motor 16 is fixedly connected to the bottom of two adjacent fixing blocks 13; the rotating shaft 14 and the first motor 16 are driven by a belt; a fixing assembly is provided on the top of the side plate 11; a monitoring camera mechanism 17 is installed on the fixing assembly; during operation, the printed ball is placed between the top plates 15, and then the two opposing first cylinders 12 are activated to stretch, which can drive the two opposing top plates 15 to move closer together, thereby clamping and fixing the ball in the middle; then the first motor 16 is activated to drive the rotating shaft 14 and the top plate 15 to rotate, which can drive the clamped ball to rotate; then the top monitoring camera mechanism is activated. The camera mechanism 17 acquires images and transmits the image data to the analysis and display device to analyze whether the printing quality is up to standard. Then, another set of opposing first cylinders 12 is activated to stretch and drive the top plate 15 to contact the ball, and the currently clamping first cylinder 12 retracts to drive the top plate 15 away from the ball. Then, the other set of first motors 16 is activated again to drive the top plate 15 and the ball to rotate again. At this time, the ball can rotate on both the X and Y axes, allowing the monitoring camera mechanism 17 to capture all the printed matter on the spherical surface. After the acquisition and analysis are completed, the first cylinder 12 is activated again to retract and drive the top plate 15 away from the ball, and then the ball is removed. Through the above structure, with the side plate 11, the first cylinder 12, and the fixing block 13, and the rotating shaft 14, the top plate 15, and the first motor 16 working together, the ball can be driven to rotate on both the X and Y axes through the two sets of opposing first cylinders 12 and the top plate 15. This improves the convenience and accuracy of rotating the ball, reducing the cumbersome process and affecting the rotation accuracy caused by manually flipping the ball.

[0025] like Figure 2 and Figure 3As shown, a vacuum pump 2 is fixedly connected to the top of the operating table 1; a through hole 21 is opened in the middle of the top plate 15; a cavity is provided inside the top plate 15; the vacuum pump 2 is connected to the top plate 15 through a conduit 23; a suction cup 22 is fixedly connected to the side wall of the top plate 15; an air hole 24 is opened in the middle of the suction cup 22; the air hole 24 is aligned with the through hole 21; during operation, the vacuum pump 2 is started to drive the airflow from the air hole 24 into the through hole 21, then through the cavity in the top plate 15, and then through the conduit 23 into the vacuum pump 2. When the top plate 15 clamps and fixes the ball, the suction cup 22 will adhere to the surface of the ball. When the airflow passes through the air hole 24... When the suction cup 22 is inserted into the top plate 15, a negative pressure is generated between the suction cup 22 and the ball, thus tightly adhering to the ball. When the top plate 15 moves away from the ball, the vacuum pump 2 is stopped first, thereby releasing the negative pressure on the suction cup 22. Then, the top plate 15 moves the suction cup 22 away from the ball. Through the above structure, the vacuum pump 2, the through hole 21, and the suction cup 22 are set up. With the use of the guide tube 23 and the air hole 24, the suction cup 22 can be adhering to the ball, and the vacuum pump 2 can generate a negative pressure in the suction cup 22. This can improve the stability of the top plate 15 when fixing the ball, and reduce the situation where the ball rotates when it is rotated, which may affect the accuracy of the shooting position.

[0026] like Figure 2 As shown, a fixing plate 3 is fixedly connected to the top of the operating table 1; a second cylinder 31 is fixedly connected to the top of the fixing plate 3; a support plate 32 is fixedly connected to the top of the second cylinder 31; during operation, when placing a ball, the support plate 32 can be raised or lowered by activating the second cylinder 31 to stretch or contract. When the size of the ball is different, the height of the support plate 32 can be adjusted to accommodate balls of different sizes. Through the above structure, the second cylinder 31 and the support plate 32 can be set so that the height of the support plate 32 can be adjusted to support balls of different sizes from the bottom, thereby improving the stability of the ball's position when rotating.

[0027] like Figure 1 and Figure 4As shown, the fixing assembly includes a fixing frame 4; the fixing frame 4 is fixedly connected to the top of the side plate 11; a slide rail 41 is fixedly connected to the end of the fixing frame 4; a second motor 42 is fixedly connected to the side wall of the slide rail 41; a bidirectional screw 43 is fixedly connected to the output end of the second motor 42; a pair of sliders 44 are symmetrically threaded in the middle of the bidirectional screw 43; a clamping plate 45 is fixedly connected to the side wall of the slider 44; during operation, when fixing the monitoring camera assembly 17, the monitoring camera assembly 17 can be placed between the clamping plates 45, and then the second motor 42 is started to drive the bidirectional screw 43 to rotate, thereby causing the sliders to move. The second motor 42 moves relative to the clamping plate 45. When the second motor 42 rotates in the forward direction, the clamping plates 45 move closer together, thereby fixing the surveillance camera mechanism 17. When the second motor 42 rotates in the reverse direction, the clamping plates 45 move away from each other, thereby releasing the fixation of the surveillance camera mechanism 17. Through the above structure, the second motor 42, the bidirectional screw 43, and the clamping plate 45 are set up to facilitate the fixing and disassembly of the surveillance camera mechanism 17, thereby improving the convenience of installation, disassembly, and maintenance of the surveillance camera mechanism 17 and reducing the cumbersome process caused by a large number of bolts.

[0028] like Figure 4 As shown, a pair of metal bellows 5 are fixed to the top of the slide rail 41; an LED light board 51 is fixed to the end of the metal bellows 5; during operation, when shooting the sphere, the LED light board 51 can be activated to emit light to supplement the surface of the sphere below. When the size of the sphere is different, the position that needs to be supplemented with light is different. At this time, the position of illumination can be changed by rotating the metal bellows 5 to drive the LED light board 51. Through the above structure, the metal bellows 5 and the LED light board 51 are set to facilitate supplementing the surface of the sphere during shooting, so as to improve the clarity when acquiring images.

[0029] like Figure 2 As shown, a plurality of ball bearings 6 are installed on the top of the support plate 32; the plurality of ball bearings 6 are evenly distributed on the top of the support plate 32; during operation, when the support plate 32 supports the ball, the ball bearings 6 will contact the surface of the ball, and when the ball rotates, it will drive the ball bearings 6 to rotate at the same time. Through the above structure, the ball bearings 6 can be set to convert the sliding friction between the ball and the support plate 32 into rolling friction, so as to reduce the situation where the printing on the surface of the ball is scratched due to excessive friction.

[0030] like Figure 4 As shown, a rubber pad 7 is fixed to the side wall of the clamping plate 45. During operation, when the clamping plate 45 clamps and fixes the surface of the surveillance camera 17, the rubber pad 7 will contact the surface of the surveillance camera 17. Through the above structure, the rubber pad 7 can increase the friction between the clamping plate 45 and the surveillance camera 17, and improve the fixing effect of the surveillance camera 17.

[0031] Working principle: The printed sphere is placed between the top plates 15. Then, the two opposing first cylinders 12 are activated to stretch, which moves the two opposing top plates 15 closer together, thus clamping and fixing the sphere in the middle. Then, the first motor 16 is activated to drive the rotating shaft 14 and the top plates 15 to rotate, which in turn causes the clamped sphere to rotate. Then, the monitoring camera 17 on the top is activated to acquire images and transmit the image data to the analysis and display device to analyze whether the printing quality is qualified. Then, another set of opposing first cylinders 12 is activated to stretch, causing the top plates 15 to contact the sphere, and the currently clamping first cylinder 12 retracts, causing the top plates 15 to move away from the sphere. Then, the process is repeated. The first motor 16 on the other set drives the top plate 15 and the sphere to rotate again. At this time, the sphere can rotate on both the X and Y axes, allowing the monitoring camera 17 to capture all the printed material on the sphere. After the acquisition and analysis are completed, the first cylinder 12 is activated to retract, moving the top plate 15 away from the sphere, and then the sphere is removed. The vacuum pump 2 is activated, driving airflow from the air hole 24 into the through hole 21, then through the cavity in the top plate 15, and then through the conduit 23 into the vacuum pump 2. When the top plate 15 clamps and fixes the sphere, the suction cup 22 will adhere to the surface of the sphere. When the airflow enters the top plate 15 through the air hole 24, it will create a negative pressure between the suction cup 22 and the sphere, thus tightly adhering them. On the sphere, when the top plates 15 move away from each other, the vacuum pump 2 is stopped first, thereby releasing the negative pressure on the suction cup 22. Then, the top plates 15 move the suction cup 22 away from the sphere. When placing the sphere, the support plate 32 can be raised or lowered by starting the second cylinder 31 to stretch or contract. When the spheres are of different sizes, the height of the support plate 32 can be adjusted to accommodate spheres of different sizes. When fixing the monitoring camera mechanism 17, the monitoring camera mechanism 17 can be placed between the clamping plates 45. Then, the second motor 42 is started to drive the bidirectional screw 43 to rotate, thereby causing the slider 44 to move relative to the clamping plates 45. When the second motor 42 rotates in the forward direction, the clamping plates 45 can be brought closer together. The surveillance camera mechanism 17 is fixed in place. When the second motor 42 rotates in the opposite direction, it can drive the clamping plates 45 to move away from each other, thereby releasing the fixation of the surveillance camera mechanism 17. When shooting the sphere, the LED light board 51 can be activated to emit light to supplement the surface of the sphere below. When the size of the sphere is different, the position that needs to be supplemented with light is different. At this time, the position of illumination can be changed by rotating the metal corrugated pipe 5 to drive the LED light board 51. When the support plate 32 supports the sphere, the ball bearing 6 will contact the surface of the sphere. When the sphere rotates, it will drive the ball bearing 6 to rotate at the same time. When the clamping plate 45 clamps and fixes the surface of the surveillance camera mechanism 17, the rubber pad 7 will contact the surface of the surveillance camera mechanism 17.
