[0022] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.
[0023] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0024] It should be noted that the anti-collision mechanism in this application is applied to a printing component, which is used to print the printing medium located on the printing plane. The printing component may be movable or immovable. This application is explained using the application of a movable printing component (printing carriage) as an example. The anti-collision mechanism is installed on the printing carriage and can move with the printing carriage.
[0025] See also Figure 1 and Figure 2 The anti-collision mechanism 1000 includes a housing 10, a curing light 20, a positioning block 30, an anti-collision assembly 40, and an anti-static bar 50. The curing light 20 and positioning block 30 are both disposed within the housing 10. The anti-collision assembly 40 and anti-static bar 50 are connected to the housing 10. The curing light 20 is connected to the inner wall of the housing 10 via the positioning block 30. The anti-collision assembly 40 can detect protruding debris on the surface of the printing medium, and the anti-static bar 50 can remove static electricity from the surface of the printing medium, preventing static electricity on the printing medium from affecting ink droplets ejected from the printhead and causing ink flying. The following describes the housing 10, curing light 20, positioning block 30, anti-collision assembly 40, and anti-static bar 50 in detail.
[0026] For the above-mentioned housing 10, curing lamp 20 and positioning block 30, as shown in FIG. Figure 1 and Figure 2 As shown, the housing 10 is provided with a mounting cavity 10a and an opening 10b connected to the mounting cavity 10a, the opening 10b facing the printing plane, and the mounting cavity 10a can be used to install the curing lamp 20, the positioning block 30 and other components. One side of the positioning block 30 is connected to the curing lamp 20, and the other side of the positioning block 30 is detachably connected to the inner wall of the housing 10. The positioning block 30 is relatively fixed to the curing lamp 20, and the curing lamp 20 is connected to the housing 10 through the positioning block 30. The curing light emitted by the curing lamp 20 can be emitted from the opening 10b.
[0027] In some embodiments, the curing lamp 20 is arranged at an inclined angle along the vertical direction. The curing light emitted by the curing lamp 20 is emitted from the opening 10b and irradiated onto the printing plane at an inclined angle. The curing light is reflected in a direction away from the printhead of the printing assembly. In this arrangement, the curing light of the curing lamp 20 is reflected at an inclined angle to other locations, and the curing light is reflected in a direction away from the printhead, thereby reducing the vertical reflection of the curing light onto the printhead of the printing assembly, thereby reducing the risk of the curing lamp 20 curing suspended ink droplets from the printhead and reducing damage to the printhead. Optionally, the curing lamp 20 is an LED curing lamp 20. It is understood that the curing lamp 20 can also be other types of lamps, such as: a pump lamp, a laser lamp, a halogen lamp, a metal halide lamp, a microwave curing lamp, etc.
[0028] It should be noted that: since the curing lamp is set at an inclined angle along the vertical direction, different inclined angles correspond to different reflection directions. Therefore, in this application, the inclined angle of the curing lamp can be set accordingly so that the curing light emitted by the curing lamp is reflected in a direction away from the nozzle, so as to avoid the curing light being directly reflected onto the nozzle.
[0029] In some embodiments, the housing 10 includes a first shell 101 and a second shell 102, the second shell 102 is detachably connected to the first shell 101, the installation cavity 10a and the opening 10b are both located on the first shell 101, and the above-mentioned static electricity removal rod 50 is installed on the second shell 102. The first shell 101 and the second shell 102 are independent of each other. This arrangement can reduce mutual interference between components in different shells.
[0030] In some embodiments, please refer to Figure 3 The housing 10 is further provided with a plurality of first positioning holes 10c communicating with the mounting cavity 10a. The plurality of first positioning holes 10c are spaced apart vertically and are used to connect to the positioning block 30. The other side of the positioning block 30 is detachably connected to at least one of the first positioning holes 10c. Because the plurality of first positioning holes 10c are spaced apart vertically, the positioning block 30 can connect to the first positioning holes 10c at different vertical positions. This allows the positioning block 30 to be tilted at different angles, thereby enabling the curing light 20 connected to the positioning block 30 to be tilted at different angles. This, in turn, allows the curing light to be irradiated onto the printing surface at different tilt angles.
[0031] In some embodiments, a plurality of the first positioning holes 10c are partially spaced apart in the horizontal direction, and the positioning block 30 connects the first positioning holes 10c at different positions in the horizontal direction, thereby enabling the positioning block 30 to be located at different positions in the horizontal direction, thereby enabling the curing light 20 connected to the positioning block 30 to be located at different positions in the horizontal direction, thereby facilitating adjustment of the horizontal position of the curing light 20 so that the curing light 20 can adapt to different application scenarios.
[0032] In some embodiments, a second positioning hole 30a is provided on one side of the positioning block 30 adjacent to the first positioning hole 10c. The second positioning hole 30a is disposed opposite one of the first positioning holes 10c. The second positioning hole 30a is connected to the first positioning hole 10c via a screw, thereby achieving a detachable connection between the positioning block 30 and the inner wall of the housing 10. It is understood that the detachable connection between the positioning block 30 and the inner wall of the housing 10 includes, but is not limited to, screw connection, clamping, riveting, threaded connection, etc., and is not specifically limited in this application.
[0033] For the above-mentioned anti-collision component 40, as Figure 1 and Figure 3 As shown, the anti-collision component 40 includes an anti-collision plate 401 and a control switch 402. One end of the anti-collision plate 401 is rotatably connected to the shell 10, and the other end of the anti-collision plate 401 is arranged close to the printing plane. The other end of the anti-collision plate 401 is attached to the outer surface of the printing medium. The control switch 402 is connected to the anti-collision plate 401, and the anti-collision plate 401 can be rotated relative to the shell 10. The control switch 402 is electrically connected to the printing component. When the anti-collision plate 401 rotates to a preset angle, the control switch 402 controls the printing component to close. It should be noted that: because the printing carriage needs to move continuously for printing, the printing carriage can drive the entire anti-collision mechanism 1000 to move, and the anti-collision plate 401 thereon moves with the printing carriage. When debris or protrusions appear on the outer surface of the printing medium, the anti-collision plate 401 will rotate to a preset angle when it contacts the debris or protrusions. After the control switch 402 receives the rotation angle-related signal of the anti-collision plate 401, the control switch 402 controls the printing carriage to stop moving and stop printing to prevent debris or protrusions from being drawn into the printing carriage and thus avoiding damage to the nozzle inside the printing carriage. Optionally, the anti-collision assembly 40 also includes a rotating shaft 403, and one end of the anti-collision plate 401 is rotatably connected to the housing 10 via the rotating shaft 403, so that the anti-collision plate 401 can rotate relative to the housing 10.
[0034] In some embodiments, please refer to Figure 4The control switch 402 includes a switch contact 4021 and a micro switch 4022. The switch contact 4021 is arranged on the rotating shaft 403, and the switch contact 4021 rotates with the rotating shaft 403. The micro switch 4022 is arranged on the housing 10. The switch contact 4021 is provided with a first connecting portion 40211 for triggering the micro switch 4022. The micro switch 4022 is provided with a second connecting portion 40221. The first connecting portion 40211 and the second connecting portion 40221 are matched with each other in a concave-convex manner. When the switch contact 4021 rotates with the rotating shaft 403, the first connecting portion 40211 deviates from the second connecting portion Part 40221, thereby triggering the micro switch 4022 to send a trigger signal. When debris or protrusions appear on the outer surface of the printing medium, the anti-collision plate 401 will rotate to a preset angle when it contacts the debris or protrusions. When the anti-collision plate 401 rotates to the preset angle, it drives the switch contact 4021 to rotate to a preset angle, and the first connecting part 40211 deviates from the second connecting part 40221, thereby triggering the micro switch 4022 to send a trigger signal. After the control unit on the printing carriage receives the trigger signal, the control unit controls the printing carriage to stop moving and stop printing to prevent debris or protrusions from being drawn into the printing carriage, thereby avoiding damage to the nozzle in the printing carriage.
[0035] It should be noted that the switch contact 4021 and the microswitch 4022 utilize a concave-convex fit. With this fit, once the switch contact 4021 rotates, it triggers the microswitch 4022, resulting in a high triggering sensitivity. For example, the second connecting portion 40221 is a bump, and the first connecting portion 40211 is a groove. In the initial state, when the microswitch 4022 is not triggered, the bump is embedded in the groove. When the switch contact 4021 rotates, the groove moves circumferentially, and the bump moves from its embedded position in the groove to the circumference of the switch contact 4021, thereby squeezing the bump toward one side of the microswitch 4022. This change in the bump's position can generate an electrical signal, thereby triggering the microswitch 4022.
[0036] For the static elimination bar 50, Figure 1 and Figure 2 As shown, one side of the anti-static rod 50 is fixed to the housing 10, and the other side of the anti-static rod 50 is arranged close to the printing medium. The anti-static rod 50 can remove static electricity from the surface of the printing medium to prevent the static electricity on the surface of the printing medium from affecting the ink droplets ejected by the nozzle on the printing carriage, causing ink flying and affecting the printing quality.
[0037] In an embodiment of the present invention, a housing 10 and a curing lamp 20 are provided. The housing 10 is provided with a mounting cavity 10a and an opening 10b communicating with the mounting cavity 10a. The opening 10b faces the printing plane. The curing lamp 20 is disposed within the mounting cavity 10a. The curing lamp 20 is disposed at an inclined angle in the vertical direction. Curing light emitted by the curing lamp 20 is emitted from the opening 10b and irradiates the printing plane at an inclined angle. The curing light is reflected in a direction away from the printhead of the printing assembly. With this arrangement, the curing light from the curing lamp 20 is reflected at an inclined angle to other locations, away from the printhead. This reduces the vertical reflection of the curing light onto the printhead of the printing assembly, thereby reducing the risk of suspended ink droplets from the curing lamp 20 curing the printhead, thereby reducing damage to the printhead.
[0038] The present invention also provides an embodiment of a printing device, which includes a printing component and the anti-collision mechanism 1000 as described above. The anti-collision mechanism 1000 is installed above the printing component. The function and structure of the anti-collision mechanism 1000 can be found in the above embodiment and will not be described in detail here.
[0039] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
