[0001] The utility model relates to the technical field of printer auxiliary equipment, in particular to a glass flatbed printer. Background Art

[0002] Traditionally, when printing pictures on glass, a UV glass flatbed printer is generally used. The UV glass flatbed printer is a machine specially used for handicraft processing. By using UV curing technology, the pictures to be printed can be directly printed on the glass, making the printing effect more durable and the color more vivid.

[0003] A glass flatbed printer disclosed in Chinese Patent CN208086795U includes a frame. A printing platform for placing glass and a printing mechanism for printing patterns on the glass placed on the printing platform are arranged on the frame. A picking and placing device for automatically placing the glass on the printing platform or automatically removing the glass with printed patterns from the printing platform is arranged on the frame. The picking and placing device includes an adsorption structure for adsorbing the glass and a moving structure for driving the adsorption structure to move. The moving structure includes a moving plate slidably arranged on the frame and a lead screw for driving the moving plate to slide on the frame.

A connecting piece for driving the glass suction cups to move along a direction perpendicular to the sliding direction of the moving plate is arranged between the moving plate and the glass suction cups. This patent can automatically place the glass on the printing platform and automatically remove the glass, saving manpower and material resources.

[0004] However, while solving the problems, the picking and placing device of this patent cannot achieve continuous flatbed printing of glass. After the operator controls the picking and placing device to transport the printed glass, subsequent adsorption and picking for printing are required. This non - continuous operation mode affects the overall work efficiency and production output. Summary of the Utility Model

[0005] In order to solve the above - mentioned existing technical problems, the utility model provides a glass flatbed printer.

[0006] The technical solution of the utility model is realized through the following scheme: A glass flatbed printer includes a support and conveying main body, a width gauge, a first guiding and limiting member, a second guiding and limiting member, and a clamping and centering device.

[0007] Through the above technical scheme, through a continuous and linear workflow, manual intervention and waiting time are reduced, so that the glass can complete the printing process more quickly, thereby improving the overall work efficiency, increasing production capacity, and realizing continuous flat-panel printing of glass. The width gauge is used to accurately measure the width of the glass to ensure the accuracy of subsequent device processing. The two guide limiters position and guide the glass to prevent deviation during the transportation process.

[0014] Preferably, the position detector is located between the supporting and conveying body and the UV printer.

[0015] Through the above technical scheme, the clamping and centering device is located between the first guide limiter and the second guide limiter, ensuring that the glass plate is firstly guided and limited during the transportation process, and then accurately centered and clamped, and finally introduced into the printing area, thereby improving the stability and accuracy of the glass plate during the transportation process. The setting of the buffer spring column can be adaptively adjusted according to glass plates of different widths, thereby improving the versatility and flexibility of the equipment.

Detailed implementation manners

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification. The present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] A glass flatbed printer, as Figures 1-5As shown in the figure, it includes a support conveyor main body, a width gauge 1, a first guiding and limiting member 2, a second guiding and limiting member 4, and a clamping and centering device 3. The width gauge 1, the first guiding and limiting member 2, the clamping and centering device 3, a position detector 7, a UV printer 5, and a monitoring system 6 are linearly installed in sequence on the support conveyor main body. A monitoring system 6 is installed on one side of the UV printer 5 away from the position detector 7. The width gauge 1 is erected at the end of the support conveyor main body. The support conveyor main body, the width gauge 1, the clamping and centering device 3, the position detector 7, the UV printer 5, and the monitoring system 6 are all communicatively connected to a control cabinet 8. The support conveyor main body consists of multiple conveyor rollers to form a conveying area. The width gauge 1 preferably uses a laser triangulation distance sensor and is erected on the support conveyor main body through a gantry support frame and is in the center position to measure the width of the glass plate and feed back the signal to the control cabinet 8, and then control the clamping and centering device 3 to make adjustments. The UV printer 5 spans across the conveyor belt of the support conveyor main body to enable the glass plate to be effectively printed in a flowing manner. The two guiding and limiting members and the clamping and centering device 3 cooperate to guide the glass plate to be aligned correctly to ensure that the glass plate will not be skewed, resulting in printing errors. The monitoring system 6 monitors the glass during printing. After printing is completed, the staff controls the glass conveyor belt to restart.

[0029] The clamping and centering device 3 is located between the first guiding and limiting member 2 and the second guiding and limiting member 4. The first guiding and limiting member 2 and the second guiding and limiting member 4 are symmetrically installed on both sides of the inner wall of the support conveyor main body. The first guiding and limiting member 2 is located at the end of the conveying area, and the second guiding and limiting member 4 is located at the end of the conveying area. The glass plate is guided into the printing area by the second guiding and limiting member 4 at the end. The middle clamping device ensures that the glass plate is in the center position during transportation. The first guiding and limiting member 2 and the second guiding and limiting member 4 installed on both sides of the inner wall of the support conveyor main body are arranged corresponding to each other to ensure that the two sides of the glass plate are not skewed by the force.

[0030] The position detector 7 is located between the support conveyor main body and the UV printer 5. The position detector 7 uses a transmissive photoelectric switch to divide the entire device into a printing area. When the glass plate is transported from the conveying area to the printing area, the position detector 7 at this time will be blocked by the glass plate and lose the signal. When the position detector 7 obtains the signal again, it means that the glass plate has completely entered the printing area. The control cabinet 8 stops the support conveyor main body from operating and conveying according to the feedback signal. The position detector 7 is close to the conveying plane to ensure that the emitted signal can be blocked by the glass plate for accurate position measurement.

[0031] The clamping and centering device 3 includes a plurality of cylinders 31, a clamping support plate 32 and a guide wheel 33. The plurality of cylinders 31 are correspondingly installed on both sides of the supporting and conveying main body. The clamping support plate 32 is installed at the telescopic end of the cylinder 31. The guide wheel 33 is installed on the bottom surface of the clamping support plate 32 close to the supporting and conveying main body. Although the guide wheel 33 is close to the glass conveying rod, there is a certain gap between it and the glass conveying rod to avoid friction damage. The cylinders 31 on the same side are in a group of two, which push the clamping support plate 32 to ensure that the clamping support plate 32 at the telescopic end is balanced in force to avoid deviation caused by uneven force. The middle device 3 also includes an infrared rangefinder 34 and a receiver 35, which are respectively installed on the corresponding clamping support plates 32. The infrared rangefinder 34 is directly opposite to the receiver 35. The infrared rangefinder 34 can detect the distance between the two relative clamping support plates 32 in real time. By cooperating with the width meter 1, the device can automatically adjust the position of the clamping support plates 32 to ensure that the clamping spacing matches the width of the glass plate, thereby improving the accuracy and efficiency of clamping. The guide wheel 33 ensures that the glass plate will not deviate from the predetermined position during the transportation process.

[0032] The first guide limiter 2 and the second guide limiter 4 have the same structure. The first guide limiter 2 includes a guide limiter, a guide wheel 22 and a buffer spring column 23. The guide limiter plate 21 is installed on the inner wall of the supporting conveying body through the buffer spring column 23. The guide limiter plate 21 is installed with a guide wheel 22 near the bottom surface of the supporting conveying body. The guide wheel 22 and the guide wheel 33 are both rubber wheels to avoid extrusion and damage to the glass plate. The guide limiter plate 21 is in a "丿" shape, and is combined with the guide limiter plate 21 set on the other side to form an "八" shape. The buffer spring column 23 can effectively hold glass plates of various widths. The buffer spring column 23 is compressed, and glass plates of various widths can easily pass through the two guide limiters. The large-scale deflection of the glass plates during transportation can be effectively limited without manual adjustment or replacement of the limiters. The single-sided guide wheel 22 is also set to be in a "丿" shape to guide the glass plates. The guide limit plate 21 is installed on the inner wall of the supporting and conveying main body through the buffer spring column 23. The guide limit plate 21 can be adaptively adjusted according to the width of the glass plates.

The contents not described in detail in this manual belong to the prior art known to professional and technical personnel in this field.

[0034] Working principle: Multiple pieces of glass to be printed are conveyed on the glass conveyor belt in sequence. After being measured for width by the width measuring instrument 1, the control cabinet 8 controls the clamping and centering device 3 to adjust until it matches the width of the glass plate. The glass plate is first limited and guided by the first guiding and limiting member 2 to prevent large deviations, and is conveyed along with the glass conveying rollers and enters the clamping and centering device 3. At this time, the clamping and centering device 3 has been adjusted, and the glass plate is placed correctly and centered for conveying;

[0035] At this time, the second glass plate is measured for width by the width measuring instrument 1 and the feedback is given, while the first glass plate has passed through the clamping and centering device 3. At this time, the clamping and centering device 3 is adjusted to ensure the centering conveyance of the subsequent glass plates;

[0036] The first glass plate passing through the clamping and centering device 3 is guided by the second guiding and limiting member 4 into the printing area. When the position detector 7 loses the signal and then receives the signal again after waiting for a period of time, it means that the glass plate has completely entered the printing area. At this time, the control cabinet 8 controls the glass conveyor belt to stop conveying, and the uv printer 5 starts printing. The monitoring system 6 conducts detection. After printing is completed, the glass conveying rollers are started to continue running. The printed glass enters the next stage. At this time, the second glass plate enters and starts printing, repeating the above operations.
