Description

Technical Field

[0001] The present application belongs to the technical field of printers, and in particular, relates to a positioning mechanism of a UV printing device. Background Art

[0002] UV printer is a high-tech full-color digital printing machine without plate making. It is not restricted by materials and can perform color photo-level printing on surfaces such as T-shirts, sliding doors, cabinet doors, sliding doors, glass, plates, various signs, crystal, PVC, acrylic, metal, plastic, stone, leather, etc. It can complete printing in one time without plate making. It has bright and rich colors, is wear-resistant, UV-proof, simple and convenient to operate, and has a fast printing speed, which fully meets industrial printing standards.

[0003] The existing foreign patent with publication number KR102652178B1 discloses a UV printing workpiece adhesion device, which allows the workpiece or other adhesive object to collect residual adhesive in the adhesive applied to the printing surface of various workpieces printed with a UV printer while minimizing the contamination of the device to protect the printed pattern and various effects, and more specifically, it consists of a base forming a slope frame, a receiver for collecting residual adhesive dropped by a flowing cleaning agent, and a dispenser for applying the adhesive to the upper surface of the adhesive object.

[0004] Although the above-mentioned UV printing device is convenient for cleaning the residues required for processing, the existing printers often fix the printed material at the center of the workbench during use, which reduces the applicability of the mechanism during use and affects the printing efficiency of the material. Summary of the invention

[0005] The purpose of this application is to provide a positioning mechanism for a UV printing device in order to solve the above-mentioned technical problems, so as to realize rapid detection of the position of the printed object after the printed object is placed on the workbench, thereby improving printing efficiency.

[0006] The present application provides a positioning mechanism of a UV printing device, including a printer body, wherein the printer body includes:

[0007] A printing table, placed on the printer body;

[0008] A printing assembly is installed on the printer body, and the printing assembly is provided with a first driving mechanism;

[0009] A positioning assembly is installed on the printer body, and the positioning assembly is provided with a second driving mechanism;

[0010] Conveyor belt, movably mounted on the printing table;

[0011] The printing table is provided with a printing area, a preparation area, and a scanning area; the positioning component is provided with a detector; and positioning grooves are provided on both sides of the conveyor belt.

[0012] The print is placed on the conveyor belt of the printing table, and the conveyor belt can be driven to move. The positioning component corresponds to the scanning area. When the print is placed on the conveyor belt and moves, the workpiece is detected by the detector on the positioning component. The detector uses an industrial camera or an infrared sensor, and is combined with the positioning groove on the conveyor belt to determine the relative position between the print and the conveyor belt. After positioning, the print is placed in the preparation area to wait. At this time, the print in the printing area prints the pattern through the printing component. The first driving mechanism is used to facilitate the movement of the printing component during printing, and the second driving mechanism is used to facilitate the position of the positioning component. When the length of the print is long, the range of the preparation area is increased by adjusting the position of the positioning component to ensure that there is a print that has been positioned while the printing area is printing, thereby improving the printing efficiency of the printer body.

[0013] Furthermore, the first driving mechanism and the second driving mechanism both include:

[0014] Adjusting motor, installed on the printer body;

[0015] The adjusting screw rod is installed and connected with the adjusting motor.

[0016] The adjusting motor drives the adjusting screw to rotate, and the adjusting screw is connected to the corresponding printing component and positioning component through a threaded pair.

[0017] Furthermore, the surface of the conveyor belt is provided with an anti-slip layer.

[0018] The outer surface of the conveyor belt has an anti-skid layer to improve the friction performance between the conveyor belt and the printer, ensuring the stability of the positional relationship between the printed part and the conveyor belt when the conveyor belt moves.

[0019] Furthermore, the conveyor belt comprises:

[0020] Connector, installed on the inner side of the conveyor belt;

[0021] Wherein, sliding parts are arranged at both ends of the connecting member, and the printing platform is provided with sliding grooves corresponding to the sliding parts.

[0022] The connecting piece is bonded or welded to the inner side of the conveyor belt, and the supporting property of the conveyor belt is improved by the connecting piece. The part of the conveyor belt placed on the side of the printing table is connected with the slide groove through the sliding part. When the conveyor belt moves, the sliding part slides in the slide groove.

[0023] Furthermore, the connecting piece includes:

[0024] A connecting groove is disposed on the sliding portion;

[0025] A connecting channel is disposed on the connecting piece and connected to the connecting groove;

[0026] A plurality of connecting holes are provided and distributed on the connecting piece;

[0027] a sealing member disposed on the sliding portion and disposed around the connecting groove;

[0028] Wherein, the conveyor belt is provided with a through hole corresponding to the connecting hole, and the printing table is provided with a plurality of air extraction holes placed in the slide groove.

[0029] The connecting groove is placed at the bottom of the sliding part, the connecting groove, the connecting channel, and the connecting hole are connected in sequence, the exhaust hole is connected to the negative pressure device, and air is sucked through the exhaust hole to generate negative pressure in the through hole, which acts on the printed part, further improving the stability of the printed part placed on the conveyor belt. The length of the connecting groove is greater than the spacing between adjacent exhaust holes, ensuring that the connecting groove is always connected to the exhaust hole, ensuring the stability of the through hole adsorbing the printed part.

[0030] Furthermore, the air extraction hole is provided with a valve body, the valve body is installed in the air extraction hole, and the slide groove is provided with a pressing portion connected to the valve body.

[0031] The opening and closing of the air extraction hole is controlled by the valve body. When the sliding part moves through the air extraction hole, the sliding part presses the pressing part corresponding to the air extraction hole, so that the valve body opens the air extraction hole. After the sliding part moves through, the valve body closes the air extraction hole again under the action of the corresponding elastic part.

[0032] The beneficial effects of this application are:

[0033] 1. When the printed workpiece is placed on the conveyor belt and moves, the detector on the positioning component detects the workpiece, and the relative position between the printed workpiece and the conveyor belt is determined in combination with the positioning groove on the conveyor belt. After positioning, the printed workpiece is placed in the preparation area and waits.

[0034] 2. When the length of the printed workpiece is long, the range of the preparation area can be increased by adjusting the position of the positioning component to ensure that a printed workpiece has been positioned while the printing area is printing, thereby improving the printing efficiency of the printer body.

[0035] 3. The air extraction hole is connected to a negative pressure device, and air is extracted through the air extraction hole to generate negative pressure in the through hole, which acts on the printed part, further improving the stability of the printed part placed on the conveyor belt.

[0050] The print is placed on the conveyor belt 500 of the printing table 200, and the conveyor belt 500 can be driven to move. The positioning component 400 corresponds to the scanning area 630. When the print is placed on the conveyor belt 500 and moves, the workpiece is detected by the detector 420 on the positioning component 400. The detector 420 uses an industrial camera or an infrared sensor, and combines with the positioning groove 510 on the conveyor belt 500 to determine the relative position between the print and the conveyor belt 500. After positioning, the print is placed in the preparation area 620 to wait. At this time, the print in the printing area 610 prints the pattern through the printing component 300. The first driving mechanism 310 is used to facilitate the movement of the printing component 300 during printing. The second driving mechanism 410 is used to facilitate the position of the positioning component 400. When the length of the print is long, the range of the preparation area 620 is increased by adjusting the position of the positioning component 400 to ensure that there is a print that has been positioned while the printing area 610 is printing, thereby improving the printing efficiency of the printer body 100.
