The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0044] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0045] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a spiral direct printing device, which includes a feeding and discharging mechanism 500, an inkjet mechanism 100 and a turntable mechanism 600. The feeding and discharging mechanism 500 conveys the workpiece to the turntable mechanism 600, thereby completing the loading of the workpiece; the turntable mechanism 600 transfers the workpiece to the position of the inkjet mechanism 100 by rotating, and the inkjet mechanism 100 completes the printing process.

[0046] In some examples, the feeding and discharging mechanism 500 is used to drive the workpiece to feed and discharge. During the feeding process, the workpiece is loaded onto the turntable mechanism 600 under the action of the feeding and discharging mechanism 500, and the workpiece can rotate on the turntable mechanism 600; during the discharging process, the workpiece is removed from the turntable mechanism 600 under the action of the feeding and discharging mechanism 500.

[0047] In some examples, such as Figure 3 and Figure 4As shown, the inkjet mechanism 100 is used to spray ink onto the workpiece. The inkjet mechanism 100 includes a guide assembly 200 and an inkjet assembly 300. The inkjet assembly 300 moves across the rotating workpiece and sprays ink onto the rotating workpiece, thereby completing the printing work. The turntable mechanism 600 is provided with a tooling 101. It can be understood that the workpiece is sleeved on the tooling 101 and rotates under the drive of the tooling 101. The inkjet assembly 300 avoids the large diameter part of the tooling 101 through the guide assembly 200 to avoid interference between the inkjet assembly 300 and the tooling 101, thereby ensuring the normal progress of the printing work.

[0048] Furthermore, the workpiece involved in the present mechanism is a cylindrical workpiece with a small diameter. Specifically, the diameter of the workpiece is less than 30 mm.

[0049] At the same time, the tooling 101 involved in the present mechanism is roughly formed into a columnar structure, and the tooling 101 can be inserted into the inner cavity of the workpiece and fit tightly with the inner cavity of the workpiece, so that the tooling 101 and the workpiece form a whole. Specifically, the part of the tooling 101 inserted into the workpiece is called the loading part. It can be understood that the diameter of the workpiece is small, and accordingly, the diameter of the tooling 101 is also small. In addition, the tooling 101 needs to be connected to a rotation drive device to ensure that the tooling 101 rotates together with the workpiece, and the tooling 101 is subject to the structural limitations of the rotation drive device, and there must be a large diameter part for connecting the rotation drive device, which is called a connecting part.

[0050] In the tooling 101, since the diameter of the loading part where the workpiece is located is smaller than the diameter of the connecting part, and the inkjet assembly 300 needs to be close to the surface of the workpiece for printing. When the inkjet assembly 300 moves to the connecting part with a large diameter, the inkjet assembly 300 in the traditional inkjet mechanism 100, i.e., the ink carriage, cannot avoid it, which easily causes the inkjet assembly 300 and the connecting part to interfere with each other. Therefore, the traditional inkjet mechanism 100 cannot print workpieces with a diameter less than 30 mm. The present application is adapted to the printing of small-diameter workpieces by setting the guide assembly 200 to avoid the connecting part of the tooling 101.

[0051] In some examples, such as Figure 3 and Figure 4 As shown, the guide assembly 200 includes a support rail, and the support rail includes a lifting portion 201. The guide assembly 200 uses the lifting portion 201 to force the inkjet assembly 300 to avoid the connecting portion with a large diameter.

[0052] Furthermore, the inkjet assembly 300 includes a plurality of motion units for inkjetting. It is worth noting that each motion unit is filled with ink of different colors, so as to print patterns of different colors on the surface of the workpiece. Since the pattern requirements on the surface of the workpiece are diverse, any color may be printed on the surface of the workpiece near the connection part. Therefore, each motion unit can move to the position of the surface of the workpiece near the connection part.

[0053] At the same time, each moving unit is carried on the support rail, and the lifting part 201 enables the height of the support rail to be raised, and the position of the lifting part 201 corresponds to the connection part of the tooling 101. When the moving unit moves to the position of the lifting part 201, the moving unit avoids the connection part by raising the height. Specifically, each moving unit is arranged horizontally and in parallel, and is independent of each other. Each moving unit can move up and down individually, so that each moving unit can reach the position of the workpiece surface close to the connection part to meet the printing requirements of multiple colors.

[0054] In some examples, the guide assembly 200 includes a first slide rail 204 which is horizontally disposed, and the inkjet assembly 300 includes a support component 301 which is slidably connected to the first slide rail 204 and moves along the first slide rail 204 .

[0055] In some examples, the support rail further includes a first straight portion 202 and a second straight portion 203, the lifting portion 201 connects the first straight portion 202 and the second straight portion 203, and the height of the first straight portion 202 is less than the height of the second straight portion. The height of the lifting portion 201 gradually increases from the first straight portion 202 to the second straight portion 203, and it can be understood that the lifting portion 201 is inclined.

[0056] The second straight portion 203 is located at the top of the connection part of the tooling 101, while the first straight portion 202 is located away from the tooling 101 and the workpiece. The moving unit moves from the first straight portion 202 to the lifting portion 201, and avoids the connection part of the tooling 101 at the lifting portion 201. At this time, the moving unit that reaches the lifting portion 201 has completed the printing work and begins to move away from the surface of the workpiece. After reaching the lifting portion 201, the moving unit further moves to the second straight portion 203.

[0057] In some examples, such as Figure 6 and Figure 7 As shown, the moving unit includes a mounting component 302. Specifically, the mounting component 302 includes a horizontal portion and a vertical portion connected to each other.

[0058] The horizontal part is provided with a nozzle 303 for inkjet, and a first guide assembly is provided between the vertical part and the support part 301. Specifically, the first guide assembly can adopt a slide rail and slider mechanism. The first guide assembly is used to guide the moving unit to move up and down relative to the support part 301, that is, to move in the vertical direction, so as to ensure that the moving unit can also move up and down along the lifting part 201 during the horizontal movement, thereby avoiding the connection part of the tooling 101.

[0059] Specifically, the mounting component 302 is provided with a rolling component 304. It can be understood that the rolling component 304 is provided at the vertical portion of the mounting component 302 and is in rolling contact with the support rail. When the motion unit moves horizontally along the support rail, the mounting component 302 forms rolling friction with the support rail through the rolling component 304, thereby ensuring the smoothness of the horizontal movement of the mounting component 302. Furthermore, the rolling component 304 adopts a bearing, and the bearing is connected to the mounting component 302 through a rotating shaft.

[0060] In some examples, the motion unit further includes an elastic component 305, and the mounting component 302 is connected to the support component 301 through the elastic component 305. Specifically, when the mounting component 302 is carried on the first straight portion 202 through the rolling component 304, the length of the elastic component 305 is relatively large, and the elastic force applied by the elastic component 305 to the mounting component 302 is relatively small; when the mounting component 302 is carried on the lifting portion 201, the length of the elastic component 305 gradually decreases, and the elastic force applied by the elastic component 305 to the mounting component 302 gradually increases; it can be understood that when the mounting component 302 is carried on the second straight portion 203, the length of the elastic component 305 is relatively small, and the elastic force applied by the elastic component 305 to the mounting component 302 is relatively large, thereby ensuring that the rolling component 304 always maintains close rolling contact with the support rail, and preventing the rolling component 304 from being separated from the support rail.

[0061] Further, when the moving unit descends from the second straight portion 203 along the lifting portion 201 to the first straight portion 202, the elastic component 305 can drive the moving unit to return to a larger length. Specifically, the elastic component 305 is a spring.

[0062] In some examples, the mounting component 302 is provided with a connecting rod, and the supporting component 301 is connected with a positioning component, specifically, the entry component is kept horizontal.

[0063] The positioning component is provided with a guide structure, and the number of the guide structures is the same as the number of the connecting rods. Specifically, the guide structure is formed as a hole structure, and the shape of the hole structure corresponds to the outer diameter of the connecting rod. The connecting rod is inserted into the guide structure and can move up and down within the range of the guide structure. The guide structure forms a guide effect for the vertical movement of the connecting rod to prevent the connecting rod from shaking in the horizontal direction. Since the connecting rod is set on the installation component 302, the guide structure can also form a guide effect for the vertical movement of the installation component 302.

[0064] Specifically, when the elastic component 305 is a spring, the elastic component 305 is sleeved on the connecting rod.

[0065] In some examples, the inkjet mechanism 100 further includes a support plate 307 , the position of the support plate 307 is fixed, and the support plate 307 is used to connect to the guide assembly 200 .

[0066] A second guide assembly is provided between the support plate 307 and the guide assembly 200. Specifically, the second guide assembly can be a slide rail or a slider mechanism. The guide assembly 200 can move up and down relative to the support plate 307 through the second guide assembly, thereby adjusting the height of the guide assembly 200, that is, adjusting the height of the inkjet assembly 300, so that the height of the inkjet assembly 300 is adapted to the workpiece mounted on the tooling 101.

[0067] In some examples, the inkjet assembly 300 further includes an inkjet housing 306, which is disposed on the support component 301 and covers each moving unit in the inner cavity. It is understandable that the inkjet housing 306 plays a certain protective role on each moving unit.

[0068] The inkjet housing 306 is provided with a height measuring device 401 , which is used to sense the height of the inkjet assembly 300 and guide the height adjustment process of the inkjet assembly 300 .

[0069] At the same time, a secondary ink path structure is fixedly provided inside the inkjet housing 306 , which is connected to each nozzle 303 and delivers ink of different colors to each nozzle 303 to ensure the printing requirements of different colors for the workpiece.

[0070] In some examples, the inkjet housing 306 is provided with a light detection device 402, and the light detection device 402 is used to provide light to the workpiece, thereby completing the detection process.

[0071] In some examples, the inkjet housing 306 is provided with an anti-collision protection device 403 , which is formed as a plate-shaped structure and is located at a side of the inkjet assembly 300 .

[0072] Specifically, when the inkjet assembly 300 moves from the first straight portion 202 to the second straight portion 203, the anti-collision protection device 403 is located in front of the inkjet assembly 300. When there is an unexpected obstruction in the moving path, the obstruction may cause a certain impact on the anti-collision protection device 403, but will not affect the inkjet machine and the internal moving units.

[0073] In some examples, such as Figure 5 As shown, the turntable mechanism 600 is located between the feeding and discharging mechanism 500 and the inkjet mechanism 100, and the turntable mechanism 600 includes a turntable body 601 and a first loading assembly and a second loading assembly, wherein the first loading assembly and the second loading assembly are arranged on the top of the turntable body 601. The turntable body 601 can rotate and drive the first loading assembly and the second loading assembly to rotate together.

[0074] Furthermore, the first loading assembly and the second loading assembly are provided with a tool 101 for loading the workpiece, and the tool 101 is formed as a rod-shaped structure. It can be understood that the workpiece is loaded on the tool 101 in a sleeve manner.

[0075] In addition, the turntable body 601 in the turntable mechanism 600 adopts a vacuum turntable, and the surface of the tooling 101 is provided with holes connected to the vacuum turntable. When the workpiece is sleeved on the tooling 101, the vacuum turntable extracts the air between the tooling 101 and the workpiece through the holes on the surface of the tooling 101, so that the space between the two forms a vacuum environment. While ensuring the connection strength between the workpiece and the tooling 101, it prevents the workpiece or the tooling 101 from being damaged by collision.

[0076] It is worth noting that the first loading assembly and the second loading assembly have different orientations. When the turntable body 601 drives the first loading assembly toward the feeding and discharging mechanism 500 by rotating, the second loading assembly faces the inkjet mechanism 100. Since the first loading assembly and the second loading assembly can simultaneously mount workpieces, the workpieces of the first loading assembly are being fed or discharged while the workpieces of the second loading assembly are being inkjet printed.

[0077] Similarly, when the turntable body 601 drives the second loading assembly toward the feeding and discharging mechanism 500 by rotation, the first loading assembly faces the inkjet mechanism 100. Since the first loading assembly and the second loading assembly can simultaneously mount workpieces, the workpieces of the second loading assembly are fed or discharged while the workpieces of the first loading assembly are inkjet printed.

[0078] In some examples, the first loading assembly and the second loading assembly both include a tool 101 and a driver 602, wherein the driver 602 is used to drive the corresponding tool 101 to rotate, thereby driving the workpiece to rotate. The driver 602 is connected to the tool 101 via a reducer 603, thereby adjusting the tool 101 to a suitable rotation speed.

[0079] Furthermore, the first loading assembly and the second loading assembly are arranged in parallel, and the tooling 101 of the first loading assembly and the tooling 101 of the second loading assembly are oriented in opposite directions, that is, the angle between the tooling 101 of the first loading assembly and the tooling 101 of the second loading assembly is about 180°.

[0080] It can be understood that the feeding and discharging mechanism 500, the turntable mechanism 600 and the inkjet mechanism 100 are arranged in a straight line, and when the turntable body 601 rotates 180°, the positions of the first loading assembly and the second loading assembly are swapped. The inkjet mechanism 100 cannot print during the process of swapping the first loading assembly and the second loading assembly, but the speed of swapping the positions of the first loading assembly and the second loading assembly is fast, which will not cause the inkjet mechanism 100 to have a long idle time. Therefore, the turntable mechanism 600 can improve the printing efficiency of the spiral direct printing device.

[0081] In some examples, such as Figure 6 As shown, the spiral direct printing device further includes a conveying mechanism 700, and the conveying mechanism 700 includes a first conveying assembly 701 and a second conveying assembly 702. The first conveying assembly 701 and the second conveying assembly 702 are stacked, and the first conveying assembly 701 is on top of the second conveying assembly 702.

[0082] Further, the first conveying assembly 701 and the second conveying assembly 702 are both used to convey the workpiece. It can be understood that there is a certain interval between the first conveying assembly 701 and the second conveying assembly 702 to facilitate accommodating the workpiece.

[0083] Specifically, the first conveying assembly 701 is used to input the workpiece into the spiral direct printing device, and the second conveying assembly 702 is used to output the workpiece from the spiral direct printing device. The conveying mechanism 700 is connected with the feeding and discharging mechanism 500, and the first conveying assembly 701 conveys the workpiece to the feeding and discharging mechanism 500, thereby completing the feeding of the workpiece; when the workpiece is printed, the feeding and discharging mechanism 500 re-conveys the workpiece to the second conveying assembly 702, and outputs the workpiece from the device.

[0084] In addition, both the first conveying assembly 701 and the second conveying assembly 702 adopt a conveyor belt structure.

[0085] In some examples, the conveying mechanism 700 further includes a steering assembly, which is disposed on the top of the first conveying assembly 701 and is used to perform a steering operation on the workpiece carried by the first conveying assembly 701 .

[0086] The steering assembly includes a first adsorption component 703 and a corresponding bracket, and the first adsorption component 703 is connected to the bracket here through a third guide component. The first adsorption component 703 is adjusted in height under the action of the third guide component, and the first adsorption component 703 approaches and adsorbs the workpiece by lowering its height. The first adsorption component 703 is raised on the premise of adsorbing the workpiece, so that the workpiece is separated from the first conveying assembly 701. Specifically, the first adsorption component 703 is a suction cup.

[0087] In addition, the first adsorption component 703 is connected to the third guide assembly through a corresponding rotating mechanism, so that the first adsorption component 703 can drive the workpiece to rotate, thereby completing the turning of the workpiece.

[0088] In some examples, such as Figure 7 As shown, the material feeding and discharging mechanism 500 includes a receiving component and a transfer component. The material feeding and discharging mechanism 500 is connected to the conveying mechanism 700. The receiving component is used to receive the workpiece to be processed and the workpiece after processing.

[0089] The receiving assembly includes a feed trough 501, which includes a feed trough and a discharge trough connected to each other, and the feed trough and the discharge trough are arranged in parallel. The first conveying assembly 701 in the conveying mechanism 700 conveys the workpiece to be processed to the feed trough, and then conveys it from the feed trough to the turntable mechanism 600. The processed parts are first conveyed from the turntable mechanism 600 to the discharge trough, and then conveyed from the discharge trough to the second conveying assembly 702. It can be seen that the feed trough 501 is formed as a transfer connection structure between the conveying mechanism 700 and the turntable mechanism 600, which is used to temporarily store the workpiece.

[0090] Furthermore, the receiving assembly further comprises a corresponding bracket, and the material inlet and outlet trough 501 is connected to the bracket via a corresponding fourth guide assembly. The material inlet and outlet trough 501 is adjusted in horizontal position under the action of the fourth guide assembly.

[0091] In addition, the transfer assembly is used to load the workpiece to be processed onto the tooling 101 on the turntable mechanism 600 , and is also used to transfer the processed workpiece to the inlet and outlet trough 501 .

[0092] In some examples, the transfer assembly includes a discharge jaw 502 and a feed push rod 503, wherein the discharge jaw 502 and the feed push rod 503 are both movably disposed on corresponding brackets.

[0093] Furthermore, a support arm is provided on the corresponding bracket, and the support arm can move horizontally on the bracket. At the same time, the discharge clamp 502 and the feed push rod 503 are arranged on the support arm and can move horizontally on the support arm. Specifically, the support arm and the bracket are horizontally moved by a slide rail and a slider mechanism, and the discharge clamp 502 and the support arm, and the feed push rod 503 and the support arm are also horizontally moved by a slide rail and a slider mechanism, and the discharge clamp 502 and the feed push rod 503 are in the same slide rail and slider mechanism.

[0094] Therefore, the discharging jaw 502 and the feeding push rod 503 can move independently relative to the support arm, and when the support arm moves horizontally relative to the bracket, the discharging jaw 502 and the feeding push rod 503 move as a whole. The support arm drives the discharging jaw 502 and the feeding push rod 503 to adjust the position of the whole, and the discharging jaw 502 and the feeding push rod 503 can also be fine-tuned independently.

[0095] At the same time, the feed push rod 503 is aligned with the feed slot. When the workpiece is in the feed slot, the feed push rod 503 moves along the extension direction of the feed slot, thereby pushing the workpiece to the fixture 101 of the turntable mechanism 600 to complete the loading of the workpiece. When the printed workpiece needs to be led out of the spiral direct printing device, the discharge clamp 502 clamps the workpiece through an opening and closing movement, thereby placing the workpiece in the discharge slot.

[0096] Specifically, the transfer assembly also includes an adsorption assembly, which includes a second adsorption component 504 and a corresponding bracket. The second adsorption component 504 is connected to the bracket through a connecting structure, and a corresponding fifth guide assembly is provided between the connecting structure and the bracket. Under the action of the fifth guide assembly, the connecting structure together with the second adsorption component 504 can move in the vertical direction. The second adsorption component 504 adopts a suction cup, and the second adsorption component 504 is used to adsorb the workpiece processed in the discharge trough and place the workpiece on the second conveying assembly 702.

[0097] In some examples, such as Figure 8 As shown, the spiral direct printing device further includes a moisturizing mechanism 800 , which is fixed in position and located away from the conveying mechanism 700 , and the height of the moisturizing mechanism 800 is smaller than the nozzle 303 of each moving unit.

[0098] The moisturizing mechanism 800 includes a plurality of moisturizing pads 801, and the number of the moisturizing pads 801 is equal to the number of the motion units. When the inkjet mechanism 100 moves to the top of the moisturizing mechanism 800 and each nozzle 303 contacts the moisturizing pad 801, the moisturizing pad 801 can moisten the nozzle 303 to prevent the nozzle 303 from being blocked.

[0099] Furthermore, the moisturizing mechanism 800 also includes a bracket for supporting the moisturizing pad 801, and each moisturizing pad 801 is movably arranged on the bracket. As each moisturizing pad 801 moves, the nozzle 303 of each moving unit is exposed to the outside, so that each nozzle 303 can be wiped.

[0100] In some examples, such as Fig. 9 As shown, the spiral direct printing device further includes a color mark positioning mechanism 901 , and the color mark positioning mechanism 901 is located at the bottom of the tooling 101 of the turntable mechanism 600 .

[0101] The color mark positioning mechanism 901 is used to sense the color mark on the surface of the workpiece, and the color mark positioning mechanism 901 includes a positioning sensor 902. The tooling 101 can drive the workpiece to rotate. When the workpiece rotates to the color mark area facing the positioning sensor 902, the positioning sensor 902 controls the tooling 101 to stop rotating through a signal, and completes the initial position positioning of the workpiece by detecting the color mark.

[0102] Furthermore, the color mark positioning mechanism 901 also includes a horizontal position adjustment component and a height adjustment component, which are respectively used to adjust the horizontal position and height of the positioning sensor 902 to adapt to the specific position of the workpiece.

[0103] Specifically, the horizontal position adjustment component may adopt a slide rail and a slider mechanism, and the height adjustment component may adopt a screw mechanism.

[0104] In some examples, such as Fig.10 As shown, the spiral direct printing device further includes a curing mechanism 903. When the inkjet mechanism 100 performs inkjet operation on the workpiece, the curing mechanism 903 is located at the side of the workpiece and performs LED curing operation on the workpiece with ink attached thereto.

[0105] Among them, LED curing can improve product quality, production efficiency and economic benefits, meet environmental protection requirements, and has high curing efficiency. The LED curing process is a photochemical reaction process, so both the ink layer and the varnish layer have the advantages of strong adhesion, durability, water resistance, chemical corrosion resistance, wear resistance, and aging resistance. The LED curing machine has very low energy consumption, which greatly reduces production costs. High speed means that the storage costs and financial pressure of raw materials and finished products can be reduced. The curing system of the LED curing machine with ink is a solvent-free system, that is, about 100% solvent-free formula, does not contain VOC, which just meets today's environmental protection requirements. The ink can dry instantly under the irradiation of the LED curing machine, and generally only takes 1 / 10S to completely dry and fix on the surface of the substrate.

[0106] Furthermore, the curing mechanism 903 includes an LED lamp 904, and the LED lamp 904 has a corresponding horizontal position adjustment component and a height adjustment component. The horizontal position adjustment component can adopt a slide rail or a slider mechanism, and the height adjustment component can adopt a screw mechanism.

[0107] In some examples, such as Fig.11 As shown, the spiral direct printing device also includes a nozzle mechanism 905, which is used to receive the end of the workpiece to ensure the horizontal position of the workpiece is stable.

[0108] The nozzle mechanism 905 includes a nozzle component 906 and a corresponding bracket, wherein the bracket is fixed in position and connected to the nozzle component 906 via a sixth guide assembly. The nozzle component 906 can be horizontally moved via the sixth guide assembly to adapt to the specific position of the workpiece.

[0109] Meanwhile, the top nozzle component 906 includes a spring, which is used to buffer the impact force provided by the workpiece to avoid damage to the workpiece caused by rigid contact between the top nozzle component 906 and the workpiece.

[0110] In some examples, the spiral direct printing device further includes a housing 1000 , and the housing 1000 is provided with input devices and alarm devices such as a touch screen 1001 , an operating console 1002 , a three-color indicator light 1003 , an exhaust fan 1004 , and a switch.

[0111] In some examples, the housing 1000 is provided with equipment such as an industrial computer 1005 and a negative pressure system 1006 to control the printing process of the workpiece as a whole.

[0112] In addition, the slide rails and slider mechanisms at various positions may have certain differences in specific forms, but all follow the guiding mode in which the slider moves along the axial direction of the slide rail.

[0113] In the actual implementation process, the conveying mechanism 700 conveys the workpiece to the feeding and discharging mechanism 500, and the feeding and discharging mechanism 500 installs the current workpiece on the tooling 101 of the turntable mechanism 600; the turntable mechanism 600 rotates, and the workpiece is driven by the turntable mechanism 600 to rotate into the working range of the inkjet mechanism 100, and the inkjet mechanism 100 prints the workpiece. At the same time, another tooling 101 on the turntable mechanism 600 rotates into the working range of the feeding and discharging mechanism 500, and the feeding and discharging mechanism 500 installs other workpieces conveyed by the conveying mechanism 700 on This idle tooling 101 allows the inkjet operation and the workpiece loading operation to be performed simultaneously, thereby reducing the idle time of the inkjet mechanism 100 and improving printing efficiency; when the workpiece within the range of the inkjet mechanism 100 is processed, the turntable mechanism 600 rotates again to return the processed workpiece to the working range of the feed and discharge mechanism 500, and the feed and discharge mechanism 500 conveys the processed workpiece to the conveying mechanism 700, thereby exporting this device, and the previously loaded workpiece arrives at the inkjet mechanism 100 for inkjet operation, and this reciprocating process is carried out for batch printing of multiple workpieces.
