DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the schemes 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.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0034] In addition, the descriptions of "first," "second," etc. in this utility model are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0035] The utility model proposes a surface printing device, referring to Figure 1 and Figure 2 , the surface printing device includes:

[0036] Base 100;

[0037] The first conveying device 200 is disposed on the base 100 and is used to convey the material to be printed;

[0038] The second conveying device 300 is disposed on the base 100 and is horizontally spaced apart from the first conveying device 200, and is used to convey the material to be printed;

[0039] The printing device 400 is arranged on the base 100 and is used to print the material to be printed conveyed by the first conveying device 200 and to print the material to be printed conveyed by the second conveying device 300.

[0040] The base 100 serves as the foundational structure of the entire surface printing system, providing support and stability for other devices. Its shape and size can be customized as needed. Connecting members, position-limiting members, and other structures can be installed on the top surface of the base 100 to mount other devices on it. Mounting structures such as mounting pins and bolt holes can be provided on the bottom surface of the base 100 to securely fasten the base 100 to the ground.

[0041] The first conveying device 200 and the second conveying device 300 are used to convey the material to be printed to the vicinity of the printing device 400, so as to complete the printing operation of the material to be printed. There are many ways to set it up. For example, taking the first conveying device 200 as an example, the first conveying device 200 can be a conveyor belt mechanism, and the material to be printed can be placed on a moving conveyor belt to complete the conveying of the material to be printed; the first conveying device 200 can also be a combination of a linear motor and a slider, and the material to be printed is placed on the slider, and the slider is driven by the linear motor to complete the conveying of the material to be printed; the material to be printed can also be conveyed by equipment such as cylinders and hydraulic presses, and this application does not impose any restrictions on this.

[0042] The first conveying device 200 and the second conveying device 300 are arranged horizontally at intervals, making the layout of the equipment more regular and rational, making full use of the installation space, and at the same time enabling the operator to more conveniently monitor the operation of the first conveying device 200 and the second conveying device 300, thereby improving the convenience and safety of operation.

[0043] During specific use, the material to be printed is first transported to the printing device 400 by the first conveying device 200 for printing operation; then the unloading operation is performed, and it returns to receive new material to be printed. During this process, the second conveying device 300 also transports the material to be printed to the printing device 400 and performs printing operation, so that the printing device 400 is continuously in working state; after completing the printing operation of the material to be printed on the second conveying device 300, the material on the second conveying device 300 is removed, and the second conveying device 300 returns to receive new material to be printed. During this process, the first device performs the loading operation and transports the new material to be printed to the printing device 400, and then repeats the above process.

[0044] Furthermore, a moving mechanism may be provided at the printing device 400 so that the printing device 400 can move back and forth between the first conveying device 200 and the second conveying device 300, thereby completing the printing operation on the material to be printed on the first conveying device 200 and the second conveying device 300; or a moving mechanism may be provided on the first conveying device 200 and the second conveying device 300 respectively so that the material to be printed extends during printing and retracts after printing is completed, thereby avoiding mutual interference between the first conveying device 200 and the second conveying device 300.

[0045] The utility model alternately conveys the material to be printed by the first conveying device 200 and the second conveying device 300 arranged at a horizontal interval, thereby reducing the idle time of the printing device 400, giving full play to the role of the printing device 400, and thus improving work efficiency. At the same time, even if one of the first conveying device 200 and the second conveying device 300 fails, it will not affect the normal operation of the other, thereby reducing the probability of the paint solidifying due to the long-term non-operation of the printing device 400.

[0046] like Figure 2-Figure 4 As shown, in some embodiments, the first conveying device 200 includes a first carrying assembly 210 and a first driving assembly 220. The first carrying assembly 210 is used to carry the material to be printed. The first driving assembly 220 is connected to the first carrying assembly 210 to drive the first carrying assembly 210 to move the material to be printed.

[0047] The second conveying device 300 includes a second bearing assembly 310 and a second driving assembly 320. The second bearing assembly 310 is used to bear the material to be printed. The second driving assembly 320 is connected to the second bearing assembly 310 to drive the second bearing assembly 310 to move the material to be printed.

[0048] Taking the first conveying device 200 as an example, the first drive assembly 220 can be a structure such as a screw, cylinder, motor, worm gear, or a combination thereof, used to provide power to transport the material to be printed. The first support assembly 210 can be of appropriate size as needed to stably support the material to be printed. The connection between the first support assembly 210 and the second drive assembly 320 can be achieved by welding, bonding, magnetic connection, threaded connection, etc., which is not limited by the present invention. The second conveying device 300 is configured similarly to the first conveying device 200 and will not be further described here.

[0049] like Figure 4 and Figure 5 As shown, in some embodiments, the first conveying device 200 further includes a first lifting mechanism 230, which is connected to the first carrying assembly 210 and the first driving assembly 220 respectively. The first lifting mechanism 230 is used to drive the first carrying assembly 210 to lift the material to be printed, and the first driving assembly 220 is used to drive the first lifting mechanism 230 to move the first carrying assembly 210;

[0050] The second conveying device 300 also includes a second lifting mechanism 330, which is respectively connected to the second bearing assembly 310 and the second driving assembly 320. The second lifting mechanism 330 is used to drive the second bearing assembly 310 to lift and lower the material to be printed, and the second driving assembly 320 is used to drive the second lifting mechanism 330 to move the second bearing assembly 310.

[0051] The first lifting mechanism 230 and the second lifting mechanism 330 are respectively used to drive the first supporting assembly 210 and the second supporting assembly 310 to move up and down, so that the first supporting assembly 210 and the second supporting assembly 310 can be at different heights when moving toward each other, thereby preventing the two from affecting each other. For example, when the first driving assembly 220 drives the first supporting assembly 210 to move toward the printing device 400 for printing, the first supporting assembly 210 is at a higher position driven by the first lifting mechanism 230; after the printing is completed, the first lifting mechanism 230 drives the first supporting assembly 210 to descend to a lower position, and the first driving assembly 220 drives the first supporting assembly 210 to return. At this time, the second driving assembly 320 also drives the second supporting assembly 310 to move toward the printing device 400, and the second supporting assembly 310 is at a higher position. Therefore, the second supporting assembly 310 and the first supporting assembly 210 are at different heights. Even if the two move toward each other, they do not affect each other, so that the surface printing device can operate smoothly.

[0052] like Figure 2 、 Figure 3 and Figure 6 As shown, in some embodiments, the first driving assembly 220 can drive the first carrying assembly 210 to move from the first initial position to the first end position, so that the printing device 400 completes the printing operation of the material to be printed; the first lifting mechanism 230 can drive the first carrying assembly 210 to descend from the first end position to the second end position; the first driving assembly 220 can drive the first carrying assembly 210 to move from the second end position to the second initial position; the first lifting mechanism 230 can drive the first carrying assembly 210 to rise from the second initial position to the first initial position;

[0053] The second driving component 320 can drive the second carrying component 310 to move from the first initial position to the first end position, so that the printing device 400 completes the printing operation of the material to be printed; the second lifting mechanism 330 can drive the second carrying component 310 to descend from the first end position to the second end position; the second driving component 320 can drive the second carrying component 310 to move from the second end position to the second initial position; the second lifting mechanism 330 can drive the second carrying component 310 to rise from the second initial position to the first initial position.

[0054] The paths of the first supporting assembly 210 and the second supporting assembly 310 are completely consistent, allowing the printing device 400 to complete printing without moving. Furthermore, during movement, the first supporting assembly 210 and the second supporting assembly 310 can be in different positions at the same time. For example, when the first supporting assembly 210 moves from the first initial position to the first final position, the second supporting assembly 310 may be moving from the second final position to the second initial position, or from the second initial position to the first initial position, thereby preventing interference between the two movements.

[0055] It is understood that the first drive assembly 220, the first lifting mechanism 230, the second drive assembly 320, and the second lifting mechanism 330 can be connected to a control device, and the control device can be used to control the travel of each component, so that the first carrier assembly 210 and the second carrier assembly 310 move along a fixed path, reducing the probability of collision between the two, while fully utilizing the printing device 400 and improving work efficiency. The control device can be a single-chip microcomputer, a host computer, etc., and this is not limited to this in the present invention.

[0056] like Figure 5 As shown, in some embodiments, the first supporting assembly 210 includes a jig 211 and an alignment platform 212. The jig 211 is arranged on the alignment platform 212. The alignment platform 212 is connected to the first driving assembly 220. The jig 211 is used to carry the material to be printed, and the alignment platform 212 is used to adjust the position and angle of the jig 211.

[0057] Since the accuracy of loading cannot be guaranteed, there will be slight differences in the position of each loading, which will often result in different printing positions, poor printing quality, and easily lead to the production of defective products. Therefore, a positioning platform 212 is set in the first supporting component 210 to adjust the position and angle of the jig 211, thereby ensuring that each material to be printed maintains the same posture during the printing process, greatly reducing errors caused by human factors, avoiding uneven printing or missed printing, and thus improving printing quality.

[0058] During specific use, the user transfers the material to be printed to the jig 211 manually or automatically. After the alignment platform 212 detects the material to be printed, it compares its actual position with the preset standard position, and adjusts the position and angle of the jig 211 according to the difference between the two until the actual position is completely consistent with the standard position. Then, the first drive component 220 or the second drive component 320 moves the material to be printed to the printing device 400 to complete the printing, thereby improving the accuracy of the present invention.

[0059] like Figure 2 and Figure 3 As shown, in some embodiments, the surface printing device also includes a CCD positioning mechanism 500, which is arranged on the base 100 and is communicatively connected to the alignment platform 212. The bottom of the CCD positioning mechanism 500 is a detection position, which is located on the path of the supporting component moving from the first initial position to the first end position, so that the CCD positioning mechanism 500 collects the position information of the material to be printed before the printing operation and sends the position information to the alignment platform 212.

[0060] Specifically, taking the first conveying device 200 as an example, after the material to be printed is transferred to the jig 211 manually or automatically, the first driving component 220 first moves the first carrying component 210 from the first initial position to the detection position, and adjusts the jig 211 to the appropriate position through the cooperation of the CCD positioning mechanism 500 and the alignment platform 212. The first driving component 220 then drives the first carrying component 210 to move from the detection position to the first end position, and the printing operation of the material to be printed is completed during the movement.

[0061] The actual position of the material to be printed is accurately detected through the CCD positioning mechanism 500, and this information is fed back to the alignment platform 212 so that the alignment platform 212 can adjust the position and angle of the fixture 211 in real time accordingly, ensuring that the material to be printed is always in the optimal printing position and angle, thereby improving the printing accuracy and quality.

[0062] like Figure 3 As shown, in some embodiments, the printing device 400 includes a mounting mechanism 410 and at least one nozzle group. The mounting mechanism 410 is connected to the base 100, and the nozzle group is arranged on the mounting mechanism 410 for completing the printing operation of the material to be printed.

[0063] There can be multiple nozzle groups, and they can print different colors. Each nozzle group includes at least one nozzle, and the mounting mechanism 410 is used to set the nozzle group in a suitable position to better complete the printing operation. Exemplarily, in this embodiment, one end of the mounting mechanism 410 is connected to the base 100, and the other end extends between the first conveying device 200 and the second conveying device 300, and is provided with a nozzle group. At the same time, the first supporting assembly 210 and the second supporting assembly 310 are also located between the first conveying device 200 and the second conveying device 300, so that the nozzle group can complete the printing operation of the material to be printed on the first supporting assembly 210 and the second supporting assembly 310 without moving.

[0064] In some embodiments, the printing device 400 further includes a UV curing mechanism, which is disposed on the mounting mechanism 410 and is used to cure the coating on the material to be printed that has been printed. By directly arranging the UV curing mechanism on the mounting mechanism 410, the coating can be cured after the printing operation is completed, thereby improving work efficiency. It is understandable that the UV curing mechanism is usually disposed after the nozzle group, that is, the material to be printed first passes through the nozzle group and completes printing, and then passes through the UV curing mechanism to complete curing. If there are multiple nozzle groups, the UV curing mechanism can be disposed at a position between the multiple nozzle groups, or it can be disposed at the last position, and the present invention does not impose any restrictions on this.

[0065] like Figure 3As shown, in some embodiments, a third lifting mechanism 420 is provided on the mounting mechanism, and the printhead assembly is connected to the third lifting mechanism 420. The third lifting mechanism 420 is used to move the printhead assembly in a vertical direction. Different types of printed materials require different printing heights. By providing the third lifting mechanism 420 in connection with the printhead assembly, the printhead assembly can be controlled to complete the printing operation at an appropriate height, making the present invention adaptable to a wider range of scenarios while improving printing quality.

[0066] like Figure 3 As shown, in some embodiments, the surface printing device also includes a recovery device 600, the recovery device 600 includes a recovery box and a third drive component, the third drive component is arranged on the base 100, the recovery box is constructed with a cavity and an opening connected to the cavity, the third drive component is connected to the recovery box, and is used to drive the recovery box to move to the printing device 400 to recover the paint in the printing device 400.

[0067] The size, dimensions, and shape of the recovery box can be adjusted based on the size of the printing device 400. During use, the recovery box is moved to the vicinity of the printing device 400 (typically below it) via a third drive member. The printing device 400 then sprays paint into the recovery box, preventing paint from being stored in the printing device 400 for extended periods and potentially causing clogging. Furthermore, a reflux channel can be provided at the bottom of the recovery box to transfer paint from the recovery box to other storage devices, such as a waste bin, to improve recycling efficiency.

[0068] The above description is only part or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
