Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a printing component and printing equipment. Background Art

[0002] Inkjet printing is a printing method that sprays tiny black or colored ink droplets onto a material. Inkjet printing recreates a digital image by spraying ink droplets onto the material. In the related art, existing inkjet printing equipment includes a spraying device, which is usually only provided with one nozzle, and the nozzle can complete the printing of a single point. By moving the spraying device linearly, linear printing can be completed, and combined with the movement of the material, printing on the entire surface of the material can be completed. However, the printing efficiency of such an inkjet printing device is low, and because the spraying device needs to move during the printing process, the ink droplets sprayed by the spraying device have a certain speed in the direction of movement of the spraying device, which makes it difficult for the ink droplets to accurately drip onto the required spraying points, thereby affecting the printing accuracy of the inkjet printing device.

[0025] In addition, by ensuring that in any of the spray hole groups, the distances between at least one spray hole and each spray hole of at least one other spray hole group in the second direction are not zero, that is, at least one spray hole and each spray hole of at least one other spray hole group are staggered in the second direction, since the material moves in the first direction, the same line on the material in the second direction will pass through different spray hole groups. Such spray holes can spray to positions that the spray holes of other spray hole groups cannot spray, which is equivalent to increasing the density of the spray holes set in the second direction of the spray hole group. When the spraying device is applied to a printing device, the printing resolution of the printing device can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] In order to facilitate understanding of the structure and technical effects of the spraying device of the present application, the present application takes the application of the spraying device to the printing equipment as an example to give an overall introduction to the printing equipment.

[0046] The technical solution of the present utility model will be further described below in conjunction with the embodiments and drawings.

[0047] See also Figure 1 An embodiment of the present invention provides a printing device 100, which includes a transport component 1 and a printing component 3. The printing component 3 is at least partially arranged above the transport component 1, and the transport component 1 is used to transport materials along a first direction X.

[0048] Optionally, the transport component 1 may be a linear motor or a conveyor belt, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0049] Optionally, the printing component 3 can be partially or completely arranged above the transport component 1, so that the printing component 3 can print above the material. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0050] In some embodiments, the printing device 100 further includes a positioning detection device 4 . The positioning detection device 4 is at least partially disposed above the transport component 1 . The positioning detection device 4 is used to detect materials.

[0051] Optionally, the positioning detection device 4 can be partially or completely located above the transport component 1, so that the positioning detection device 4 can perform detection above the material. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0052] In some embodiments, the printing device 100 further includes a material carrier 2 , which is used to carry materials.

[0053] The structures of the printing assembly 3 , the positioning detection device 4 and the material carrier 2 will be described in detail below with reference to the accompanying drawings.

[0054] See also Figure 1In some embodiments, the printing device 100 includes a support structure 3b and a spraying device 3a, wherein the spraying device 3a is disposed on the support structure 3b. The support structure 3b is used to support the spraying device 3a so that the spraying device 3a can be positioned above the material for printing.

[0055] Please also refer to Figures 2 to 5 In some embodiments, the spraying device 3a includes a mounting seat 30, a liquid storage component 31, a valve 32 and a pumping component 33. The liquid storage component 31 is provided on the mounting seat 30 and is used to store the spraying liquid. The valve 32 is provided on the mounting seat 30. The valve 32 has multiple groups of spraying hole groups 32a. The multiple groups of spraying hole groups 32a are arranged at intervals along the first direction X. Each group of spraying hole groups 32a has multiple spraying holes 320 arranged at intervals along the second direction Y. In any spraying hole group 32a, the distance between at least one spraying hole 320 and each spraying hole 320 of at least one other spraying hole group 32a in the second direction Y is not zero. The pumping component 33 is provided on the mounting seat 30, and the pumping component 33 is connected to the liquid storage component 31 and the valve 32. The pumping component 33 is used to pump the spraying liquid in the liquid storage component 31 to the valve 32.

[0056] It can be understood that the above-mentioned first direction X is the direction in which the transport component 1 transports the material, and the second direction Y is a direction intersecting with the first direction X. Since the spraying device 3a performs two-dimensional spraying on the upper surface of the material, the second direction Y can usually be made perpendicular or approximately perpendicular to the first direction X, and the first direction X and the second direction Y can be made perpendicular or approximately perpendicular to the height direction Z of the printing device 100.

[0057] In this way, the mounting seat 30 can carry the various components of the spray device 3a (such as the liquid storage component 31, the valve 32 and the pumping component 33, etc.). The liquid storage component 31 can store the spray liquid that the spray device 3a needs to spray. The pumping component 33 can provide power for the spray liquid and pump the spray liquid in the liquid storage component 31 to the valve 32. The valve 32 can control the opening or closing of each spray hole 320 respectively. When the valve 32 controls any spray hole 320 to open, under the action of the pumping component 33, the spray liquid can be sprayed out from the spray hole 320, so that the spray hole 320 is printed at the position on the material corresponding to the height direction Z of the spray device 3a. When the valve 32 controls any spray hole 320 to close, no spray liquid will be sprayed out of the spray hole 320.

[0058] By providing the valve 32 with multiple groups of spray hole groups 32a spaced apart along the first direction X, and each of the multiple spray hole groups 32a having multiple spray holes 320 spaced apart along the second direction Y, when the spray device 3a is applied to the printing device 100, the multiple spray holes 320 of one spray hole group 32a can simultaneously spray the material at multiple locations in the second direction Y, and the multiple spray hole groups 32a can operate simultaneously, thereby improving the printing efficiency of the spray device 3a. Furthermore, during the printing process, the spray device 3a does not need to move in the second direction Y; it only needs to move the material in the first direction X to complete printing on the object. This can avoid the spray liquid sprayed by the spray device 3a having a certain speed in the first direction X, which makes it difficult for the spray liquid to accurately drip onto the desired spraying point, thereby improving the printing accuracy of the spray device 3a.

[0059] In addition, by ensuring that in any of the spray hole groups 32a, the distances between at least one spray hole 320 and the spray holes 320 of at least one other spray hole group 32a in the second direction Y are not zero, that is, at least one spray hole 320 and the spray holes 320 of at least one other spray hole group 32a are staggered in the second direction Y, since the material moves in the first direction X, the same line of the material in the second direction Y will pass through different spray hole groups 32a, such spray holes 320 can spray positions that the spray holes 320 of other spray hole groups 32a cannot spray, which is equivalent to increasing the density of the spray holes 320 set in the second direction Y of the spray hole group 32a. When the spraying device 3a is applied to the printing equipment 100, the printing resolution of the printing equipment 100 can be improved.

[0060] Optionally, the spraying liquid may be ink or glue, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0061] Optionally, in any one spray hole group 32a, the distances between one spray hole 320 or multiple spray holes 320 (for example, two, three or four, etc.) or all spray holes 320 and each spray hole 320 of another spray hole group 32a in the second direction Y are not zero, or the distances between one spray hole 320 or multiple spray holes 320 or all spray holes 320 and each spray hole 320 of multiple (for example, two, three or four, etc.) other spray hole groups 32a in the second direction Y are not zero, such as Figure 5 As shown, the distances between one spray hole 320 or multiple spray holes 320 or all spray holes 320 and all other spray holes 320 in the spray hole group 32a in the second direction Y may not be zero. The specific distances may be selected according to actual conditions and are not specifically limited in this embodiment.

[0062] In some embodiments, the distance between any two spray holes 320 of the valve 32 in the second direction Y is not zero. That is, the spray holes 320 of all spray hole groups 32a on the valve 32 are staggered in the second direction Y.

[0063] In this way, when the material moves in the first direction X, when the same line on the material in the second direction Y passes through different spray hole groups 32a, any position on the line (which can be regarded as a point) will not repeatedly pass through the spray holes 320 of different spray hole groups 32a, that is, any position on the line will only pass through one spray hole 320 when passing through the spray holes 320 of different spray hole groups 32a. Under the premise of ensuring the printing efficiency and printing accuracy of the spray device 3a, the utilization rate of the spray holes 320 can be improved, the number of spray holes 320 set can be reduced, and the production cost and processing difficulty of the valve 32 can be reduced.

[0064] It can be understood that when such a spraying device 3a prints the material, the same line of the material in the second direction Y passes through different spray hole groups 32a, which is equivalent to being printed by a large spray hole group formed by a combination of multiple spray hole groups 32a. The above-mentioned large spray hole group is arranged along the second direction Y and has all the spray holes 320 of all the spray hole groups 32a of the valve 32. Due to the limitations of the internal structural design of the valve 32, the gap between two adjacent spray holes 320 in the second direction Y (that is, the distance between the edges of the two spray holes 320) is difficult to approach zero and cannot be zero. If only one spray hole group 32a is set on the valve 32, that is, there is only one plurality of spray holes 320 spaced apart along the second direction Y, such a valve 32 is difficult to achieve higher printing resolution. However, by adopting the spraying device 3a of the present application, by setting multiple spray hole groups 32a, the distance between two adjacent spray holes 320 of a large spray hole group formed by multiple spray hole groups 32a can be close to zero, and even the distance between two adjacent spray holes 320 can be zero, that is, the large spray hole group corresponds to a long strip hole, thereby better improving the resolution of the printing device 100.

[0065] Optionally, the selection can be made in the same spray hole group 32a according to actual conditions, and is not specifically limited in this embodiment.

[0066] In some embodiments, in the same spray hole group 32a, the distance between two adjacent spray holes 320 in the second direction Y is the same. That is, the multiple spray holes 320 in the same spray hole group 32a are evenly spaced in the second direction Y.

[0067] In this way, on the one hand, the distribution of multiple spray holes 320 in the second direction Y can be made more uniform, which is beneficial to improving the uniformity of the spray device 3a in the second direction Y when printing the material, and reducing the occurrence of some positions on the material that cannot be printed due to the uneven distribution of the spray holes 320. On the other hand, it can reduce the design and processing difficulty of the valve 32.

[0068] In this embodiment, the distance between two adjacent spray holes 320 in each spray hole group 32a in the second direction Y is the same. This helps to further improve the uniformity of the spray device 3a in printing on the material in the second direction Y, and at the same time, it can further reduce the difficulty of designing and manufacturing the valve 32.

[0069] In some embodiments, the number of spray hole groups 32a is a. In the same spray hole group 32a, the distance between two adjacent spray holes 320 in the second direction Y is D. In any two spray hole groups 32a, the distance between the two spray holes 320 closest to each other in the second direction Y is d, satisfying the relationship: d = (n / a) * D, where n < a, and n and a are both positive integers. That is, the distance between any two adjacent spray holes 320 in a large spray hole group formed by multiple spray hole groups 32a is equal and is d. In this embodiment, the distance between two spray holes 320 refers to the distance between the centers of the two spray holes 320.

[0070] In this way, the uniformity of the spray device 3a in the second direction Y when printing the material can be greatly improved, avoiding the situation where some positions on the material cannot be printed due to uneven distribution of the spray holes 320, so that when the spray device 3a is applied to the printing equipment 100, the actual printing resolution printed is closer to the ideal printing resolution during design.

[0071] For example, if the number of spray hole groups 32a is 4, the relationship is satisfied: d = (n / 4) * D, where n is less than 4 and n is a positive integer. Then, one of the spray hole groups 32a is used as a reference, and the distances between the remaining three spray hole groups 32a and the two spray holes 320 closest to the spray hole group 32a in the second direction Y are 1 / 4D, 2 / 4D, and 3 / 4D, respectively. The arrangement order of the four spray hole groups 32a in the first direction X can be selected according to actual conditions and is not specifically limited in this embodiment.

[0072] In some embodiments, there are multiple valves 32 , and the multiple valves 32 are arranged along the first direction X. The distance between any two spray holes 320 of the multiple valves 32 in the second direction Y is not zero.

[0073] In this way, multiple valves 32 can be used in combination. In the process of the material moving in the first direction X, when the same line of the material in the second direction Y passes through the various spray hole groups 32a of different valves 32, any position on the line (which can be regarded as a point) will not repeatedly pass through the spray holes 320 of different spray hole groups 32a, that is, any position on the line will only pass through one spray hole 320 when passing through the spray holes 320 of different spray hole groups 32a. Under the premise of ensuring the printing efficiency and printing accuracy of the spraying device 3a, the utilization rate of the spray holes 320 can be improved, the number of spray holes 320 set can be reduced, and the production cost and processing difficulty of the valve 32 can be reduced.

[0074] In some embodiments, the total number of spray hole groups 32a of multiple valves 32 is a, and in the same spray hole group 32a, the distance between two adjacent spray holes 320 in the second direction Y is D. In any two spray hole groups 32a, the distance between the two spray holes 320 closest to each other in the second direction Y is d, satisfying the relationship: d = (n / a) * D, where n < a, and n and a are both positive integers.

[0075] In this way, when multiple valves 32 are used in combination, the uniformity of the spray device 3a in printing the material in the second direction Y can be greatly improved, avoiding the situation where some positions on the material cannot be printed and sprayed due to uneven distribution of the spray holes 320, so that when the spray device 3a is applied to the printing equipment 100, the actual printing resolution printed is closer to the ideal printing resolution during design.

[0076] For example, Figure 4 and Figure 5 As shown, if there are two valves 32, the number of spray hole groups 32a of each valve 32 is 8, and the total number of spray hole groups 32a of the two valves 32 is 16, then the relationship is satisfied: d = (n / 16) * D, where n < 16, and n is a positive integer. Then, one of the spray hole groups 32a is used as a reference, and the remaining fifteen spray hole groups 32a are the two spray hole groups 320 closest to the spray hole group 32a in the second direction Y. The distances between them are 1 / 16D, 2 / 16D, 3 / 16D, 4 / 16D, 5 / 16D, 6 / 16D, 7 / 16D, 8 / 16D, 9 / 16D, 10 / 16D, 11 / 16D, 12 / 16D, 13 / 16D, 14 / 16D, and 15 / 16D, respectively. The arrangement order of the sixteen spray hole groups 32a in the first direction X can be selected according to actual conditions and is not specifically limited in this embodiment.

[0077] See also Figure 2In some embodiments, the mounting base 30 includes a back plate 300, a first side plate 301, a second side plate 302 and a bottom plate 303. The first side plate 301 and the second side plate 302 are connected to both sides of the back plate 300 along the second direction Y. The bottom plate 303 is connected to the back plate 300, the first side plate 301 and the second side plate 302 to enclose an installation space 305. The liquid storage component 31 is arranged in the installation space 305. The valve 32 is arranged on the bottom plate 303 and is located in the installation space 305. The bottom plate 303 is provided with an avoidance portion 303a connected to the installation space 305 to avoid the spray hole 320.

[0078] In this way, the back plate 300, first side plate 301, second side plate 302, and bottom plate 303 of the mounting base 30 can enclose a mounting space 305, so that components such as the liquid storage component 31, valve 32, and pumping component 33 are all accommodated in the same space, making the structural layout of the spraying device 3a more compact and protecting the pipes connecting the pumping component 33 to the liquid storage component 31 and valve 32. By providing an avoidance portion 303a on the bottom plate 303 that is connected to the mounting space 305, the avoidance portion 303a can avoid the spraying hole 320 of the valve 32, ensuring that the spraying liquid ejected from the valve 32 can drip onto the material.

[0079] Optionally, the avoidance portion 303a may be a through hole or a through groove that passes through the bottom plate 303, and the specific selection may be made according to actual conditions and is not specifically limited in this embodiment.

[0080] In some embodiments, the spraying device 3a further includes a mounting member 35 and a first movable mechanism 34. The mounting member 35 is configured to be connected to the printing assembly 3. The first movable mechanism 34 is disposed on the mounting member 35, and the backplate 300 is disposed on the first movable mechanism 34. The first movable mechanism 34 is configured to move the backplate 300 relative to the mounting member 35 in the height direction Z of the spraying device 3a. The provision of the mounting member 35 facilitates the installation of the spraying device 3a on the support structure 3b of the printing assembly 3. The provision of the first movable mechanism 34 enables the backplate 300 to move relative to the mounting member 35 in the height direction Z of the spraying device 3a, thereby adjusting the valve 32 to an appropriate height, ensuring a suitable distance between the valve 32 and the material on the transport assembly 1, and facilitating the spraying device 3a to print the material.

[0081] Optionally, the mounting member 35 may be a plate-shaped structure or a block-shaped structure, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0082] Optionally, the first moving mechanism 34 may be a linear motor or a hydraulic push rod, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0083] In some embodiments, the mounting base 30 further includes a support plate 304, which is connected to the first side plate 301 and the second side plate 302 and is spaced apart from the back plate 300 along the first direction X. The liquid storage component 31 is disposed on the support plate 304. The spraying device 3a further includes a first pipe 36, a conductive member, and a control mainboard 37. One end of the first pipe 36 is slidably disposed between the support plate 304 and the back plate 300, and the other end of the first pipe 36 is connected to the mounting member 35. The control mainboard 37 is disposed on the first side plate 301 or the second side plate 302, and is electrically connected to the valve 32 and the pumping component 33. The conductive member is disposed in the first pipe 36, one end of the conductive member is electrically connected to the control mainboard 37, and the other end of the conductive member is used to be electrically connected to an external power source.

[0084] In this way, the support plate 304 can support the liquid storage component 31 and form a certain spacing between it and the back plate 300. The support plate 304 can provide a certain shielding and protection for the conductive components and circuits between the support plate 304 and the back plate 300 (the circuits refer to the electrical connection structure between the control main board 37 and the valve 32 and the pumping component 33), thereby improving the aesthetic appearance and safety of the spraying device 3a. The conductive components can be electrically connected to the control main board 37 and an external power supply, and the control main board 37 can be powered by the external power supply. By setting up the first pipe 36, the first pipe 36 can accommodate a conductive part for connecting to the control main board 37 and the external power supply, further improving the aesthetic appearance and safety of the spray device 3a. In addition, when the back plate 300 moves along the height direction Z of the spray device 3a, the first pipe 36 is fixed relative to the mounting part 35, and the support plate 304 and the back plate 300 slide relative to the first pipe 36. The accommodating cavity of the first pipe 36 can provide a guiding effect for the movement of the conductive part, thereby reducing the phenomenon of disordered movement of the conductive part during the movement of the back plate 300, causing entanglement, pulling, or even breakage.

[0085] Optionally, the conductive member may be a cable or a conductive metal wire, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0086] Since the spraying liquid is stationary in the liquid storage component 31 and the valve 32 when the spraying device 3a is not performing printing operations, the spraying liquid may solidify (especially when the spraying liquid is glue), causing the liquid storage component 31 to be blocked and unable to normally provide the spraying liquid, or causing the spraying hole 320 of the valve 32 to be blocked and unable to normally spray the spraying liquid. Based on this, please refer to Figure 2 、 Figure 6 and Figure 7In some embodiments, the liquid storage component 31 includes a first storage part 310 and a second storage part 311, and the first storage part 310 and the second storage part 311 are arranged in the installation space 305 at intervals along the second direction Y. The pumping component 33 is connected to the first storage part 310 and the second storage part 311. The valve 32 is provided with a first connection part 321 and a second connection part 322. The first connection part 321 and the second connection part 322 are connected to each spray hole 320. The first connection part 321 is connected to the first storage part 310, and the second connection part 322 is connected to the second storage part 311. The pumping component 33 is used to circulate and pump the spraying liquid along the first storage part 310, the first connection part 321, the second connection part 322, and the second storage part 311 in sequence.

[0087] In this way, the spraying liquid can circulate between the valve 32 , the first storage part 310 and the second storage part 311 , reducing the possibility of the spraying liquid solidifying and causing blockage of the liquid storage part 31 and the spraying hole 320 of the valve 32 .

[0088] Optionally, the first connection portion 321 and the second connection portion 322 may be holes provided on the valve 32 or hollow pipes. The specific selection may be made according to actual conditions and is not specifically limited in this embodiment.

[0089] Please refer again Figure 1 Optionally, the support structure 3b may be a gantry or cantilever frame, etc., and the specific selection can be made according to actual conditions and is not specifically limited in this embodiment. Taking the gantry as an example, when the support structure 3b is applied to the printing device 100, it is placed above the transport component 1 of the printing device 100, so that the spray device 3a disposed on the support structure 3b can directly print the materials located on the transport component 1. This facilitates the simultaneous printing of materials during transportation, eliminating the need to move the materials to other workstations for printing, and improving printing efficiency.

[0090] In some embodiments, the support structure 3b may be provided with a second movable mechanism 38 for moving the spraying device 3a along the second direction Y. The second movable mechanism 38 can adjust the position of the spraying device 3a in the second direction Y, allowing the spraying device 3a to align with the material on the transport assembly 1 in the second direction Y. Furthermore, if multiple transport assemblies 1 are provided in the second direction Y, the spraying device 3a can print on the materials on the multiple transport assemblies 1 separately.

[0091] Optionally, the second moving mechanism 38 may include a slide rail and a slider, or may include a guide rail and a roller, etc. The specific selection may be made according to actual conditions and is not specifically limited in this embodiment.

[0092] Please also refer to Figure 8 and Figure 9 In some embodiments, the positioning detection device 4 includes a support frame 40, a visual detection module 41 and a height sensor 42. The support frame 40 is configured to be at least partially disposed above the transport component 1. The support frame 40 has a first side 400 and a second side 401 opposite to each other along the first direction X. The visual detection module 41 is disposed on the first side 400. The visual detection module 41 is used to obtain an image of the material located on the transport component 1. The height sensor 42 is disposed on the second side 401. The height sensor 42 is used to detect the height of the material.

[0093] Thus, the support frame 40 is used to support components such as the visual inspection module and height sensor 42, allowing the visual inspection module 41 and height sensor 42 to be positioned above the material for material inspection. By arranging the visual inspection module 41 and height sensor 42, the visual inspection module 41 can capture an image of the material, thereby obtaining information about the material's position within a two-dimensional plane. The height sensor 42 can detect the material's height, thereby obtaining information about the material's position in the height direction Z.

[0094] When the positioning detection device 4 is applied to the printing device 100, the printing device 100 can position the material according to the position information of the material in the two-dimensional plane obtained by the positioning detection device 4, so as to adjust the printing position of the spraying device 3a of the printing device 100 on the material, and reduce the offset of the printing of the printing device 100 on the material. At the same time, the printing device 100 can also adjust the printing height of the spraying device 3a according to the position information of the material in the height direction Z obtained by the positioning detection device 4, so that there is a suitable distance between the spraying device 3a and the material. In addition, when printing materials with uneven surfaces, the inclination degree of the slope of the material surface is obtained according to the position information of the material in the height direction Z, and the spraying device 3a can adjust the size of the spraying liquid sprayed according to the inclination degree of the slope of the material surface, thereby improving the accuracy of material printing.

[0095] In addition, the visual detection module 41 and the height sensor 42 are respectively arranged on the first side 400 and the second side 401 of the support frame 40 opposite to each other in the first direction X. The visual detection module 41 and the height sensor 42 are integrated on the same support frame 40. The structural design of the positioning detection device 4 is relatively compact, which can reduce the space occupied by the positioning detection device 4. Moreover, when the material moves along the first direction X on the transport component 1, it can pass through the visual detection module 41 and the height sensor 42 in sequence at a faster speed, which is beneficial to improve the efficiency of the positioning detection device 4 in detecting materials.

[0096] Optionally, the support frame 40 may be a gantry frame or a cantilever frame, etc., and the specific selection can be made according to actual conditions and is not specifically limited in this embodiment. Taking the support frame 40 as a gantry frame as an example, when the support frame 40 is applied to the printing device 100, it is placed above the transport component 1 of the printing device 100, so that the visual inspection module 41 and height sensor 42 provided on the support frame 40 can directly inspect the materials located on the transport component 1. This facilitates the simultaneous inspection of materials during transportation, eliminating the need to move the materials to other workstations for inspection, and improving inspection efficiency.

[0097] Optionally, the height sensor 42 may be a laser ranging sensor or an infrared sensor, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0098] In some embodiments, the visual detection module 41 includes a light source assembly 41a and a visual sensor 41b. The light source assembly 41a includes a light source body 410, a first connecting member 411 and a second connecting member 412. The first connecting member 411 and the second connecting member 412 are arranged on the first side 400, and the first connecting member 411 and the second connecting member 412 are arranged at intervals along the second direction Y. The light source body 410 is connected to the first connecting member 411 and / or the second connecting member 412. The visual sensor 41b is arranged on the first side 400 and is located between the first connecting member 411 and the second connecting member 412.

[0099] In one example, the light source body 410 is connected to the first connecting member 411 .

[0100] In another example, the light source body 410 is connected to the second connecting member 412 .

[0101] In another example, the light source body 410 is connected to the first connecting member 411 and the second connecting member 412 .

[0102] In this way, the visual sensor 41b can acquire an image of the material located on the transport component 1, and the light source component 41a can provide light for the visual sensor 41b, so that the visual sensor 41b can acquire an image at an appropriate brightness, thereby improving the imaging effect of the visual sensor 41b. The first connecting member 411 and the second connecting member 412 can support the light source component 41a. By arranging the visual sensor 41b between the first connecting member 411 and the second connecting member 412, on the one hand, the light provided by the light source component 41a can cover the field of view of the visual sensor 41b, and on the other hand, the visual detection module 41 can be arranged more compactly, reducing the space occupied by the visual detection module 41.

[0103] Optionally, the visual sensor 41b may be a line scan camera or a scanner, etc., and the specific selection can be made based on actual conditions and is not specifically limited in this embodiment. When the visual sensor 41b is a line scan camera, the visual sensor 41b images a straight line of the material in the second direction Y. By moving the material in the first direction X by the transport assembly 1, an image of the material in a two-dimensional plane can be obtained.

[0104] Optionally, the first connecting member 411 and the second connecting member 412 may be plate-shaped structures or rod-shaped structures, etc., which can be selected according to actual conditions and are not specifically limited in this embodiment.

[0105] In some embodiments, the light source body 410 includes a line scanning light source 410a, and the light source body 410 has at least a partial light-transmitting area 4101. Along the height direction Z of the support frame 40, the visual sensor 41b is located at the upper part of the light source body 410 and the visual sensor 41b is set corresponding to the light-transmitting area 4101.

[0106] In this way, the line scanning light source 410a can provide linear light to the material through the light-transmitting area 4101. At the same time, the visual sensor 41b can photograph the material through the light-transmitting area 4101 of the line scanning light source 410a. Through the cooperation of the light source body 410 and the visual sensor 41b, the brightness adjustment and linear photography of the material are realized.

[0107] In some embodiments, the first connecting member 411 and the second connecting member 412 extend along the height direction Z of the support frame 40, and a first clamping portion 4100 is provided on the light source body 410. The first connecting member 411 and / or the second connecting member 412 are provided with multiple second clamping portions 4110, and the multiple second clamping portions 4110 are arranged at intervals along the height direction Z of the support frame 40. The first clamping portion 4100 can be detachably connected to any second clamping portion 4110 to adjust the position of the light source body 410 relative to the first connecting member 411 and the second connecting member 412.

[0108] In one example, the first connecting member 411 is provided with a plurality of second clamping portions 4110 .

[0109] In another example, the second connecting member 412 is provided with a plurality of second clamping portions 4110 .

[0110] In another example, the first connecting member 411 and the second connecting member 412 are provided with a plurality of second clamping portions 4110 .

[0111] In this way, by setting a first clamping portion 4100 on the light source main body 410, and providing multiple second clamping portions 4110 on the first connecting member 411 and the second connecting member 412, and by connecting the first clamping portion 4100 to different second clamping portions 4110, the position of the light source main body 410 relative to the first connecting member 411 and the second connecting member 412 can be adjusted, thereby adjusting the height of the light source main body 410, so that there is a suitable distance between the light source main body 410 and the visual sensor 41b and the material, so that the light source main body 410 can better provide light for the visual sensor 41b.

[0112] Optionally, one of the first clamping portion 4100 and the second clamping portion 4110 may be a convex portion, and the other may be a groove; or, the first clamping portion 4100 and the second clamping portion 4110 may both be screw holes, and a detachable connection is achieved by additionally provided bolts.

[0113] In some embodiments, the material carrier 2 includes a carrying platform 20 . The carrying platform 20 is slidably disposed on the transport assembly 1 along a first direction X. The carrying platform 20 is used to carry and absorb the material.

[0114] In this way, the carrying platform 20 adsorbs the material, so that when the carrying platform 20 transports the material along the first direction X, the material is fixed relative to the carrying platform 20, thereby preventing the material from shifting or even falling off during transportation, detection and printing, thereby improving the accuracy of the positioning detection device 4 in detecting the position information of the material, and the printing accuracy when the printing component 3 prints the material according to the position information of the material detected by the positioning detection device 4.

[0115] Optionally, the carrying platform 20 may include a vacuum adsorption device or a magnetic adsorption device, etc., which can be selected according to actual conditions and is not specifically limited in this embodiment.

[0116] In some embodiments, the material carrier 2 further includes a display device 21 . The display device 21 is disposed on a side of the carrying platform 20 . The display device 21 is used to display the state of the material adsorbed by the carrying platform 20 .

[0117] Thus, by providing the display device 21, the user can monitor the material adsorption status of the carrier platform 20 in real time. Even if the material adsorption is poor and may deviate or even detach, the user can stop printing in time and repair the carrier platform 20. In addition, the display device 21 is provided on the side of the carrier platform 20, which makes it easy for the user to observe the display device 21. At the same time, the space on the side of the carrier platform 20 is reasonably utilized, and no additional supporting structure is required to install the display device 21.

[0118] For example, when the carrying platform 20 includes a vacuum adsorption device, the display device 21 may include a vacuum display meter.

[0119] The following describes the process of printing a material using the printing device 100 of the present application:

[0120] First, place the material to be inspected on the carrying platform 20 of the material carrier 2, so that the carrying platform 20 adsorbs the material. After the display device 21 shows that the adsorption of the material is normal, the transport component 1 transports the carrying platform 20 along the first direction X. After moving the material to the bottom of the visual inspection module 41, the material passes through the visual inspection module 41 at a uniform speed. The visual inspection module 41 obtains the position information of the material in the two-dimensional plane, and then continues to move the material to the bottom of the height sensor 42. The height sensor 42 obtains the height position information of the material, completing the positioning detection of the material. After the transport component 1 transports the material that has completed the positioning detection to the bottom of the spraying device 3a, the material passes through the spraying device 3a at a uniform speed. The spraying device 3a controls the corresponding spray hole 320 to open according to the position where the material needs to be printed, and spray prints the material. After multiple sprayings, the printing of the material is completed. After the printing of the material is completed, the transport component 1 moves the carrying platform to the material unloading position.

[0121] The above is a detailed introduction to the spraying device, printing assembly and printing equipment disclosed in the embodiments of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the spraying device, printing assembly and printing equipment of the present invention and their core ideas; at the same time, for general technical personnel in this field, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
