[0042] The UV inkjet equipment provided in this embodiment, such as Figures 1 to 8 As shown, it includes a first conveying path 2, a second conveying path 3, a surface treatment mechanism 4, an inkjet mechanism 5, a flash spray assembly 6, a material transfer mechanism 7, and a quality inspection mechanism 8. The following will combine... Figures 1 to 8 The connection relationship and working principle of the aforementioned components are described in detail.

[0043] like Figure 1 As shown, Figure 1A schematic diagram of a top view of a UV inkjet equipment is shown. The first conveyor path 2, the second conveyor path 3, the surface treatment mechanism 4, the inkjet mechanism 5, the flash spray assembly 6, the material transfer mechanism 7, and the quality inspection mechanism 8 can all be mounted on the machine base 1. The first conveyor path 2 and the second conveyor path 3 are arranged in parallel, alternately conveying the workpiece to be processed. The material transfer mechanism 7 enables the workpiece to be processed to flow between the first conveyor path 2 and the second conveyor path 3. Through the cooperation of the first conveyor path 2 and the second conveyor path 3, the workpiece to be processed can be conveyed sequentially through the surface treatment mechanism 4, the inkjet mechanism 5, and the quality inspection mechanism 8, completing the surface treatment, inkjet processing (including inkjet and UV curing), and inkjet quality inspection of the workpiece. The flash spray assembly 6 is used to clean the inkjet head 55 of the inkjet mechanism 5 to prevent the inkjet head 55 from clogging and affecting the inkjet processing of the workpiece.

[0044] In this embodiment, the first conveying path 2 is set on the machine base 1, which includes multiple independently set variable-pitch conveyor lines 21 and a roller conveyor line 22. The roller conveyor line 22 is connected to the variable-pitch conveyor line 21 and is located below the quality inspection mechanism 8. It should be emphasized that within the travel range of the second conveying path 3, the variable-pitch conveyor line 21 on the corresponding conveying section of the first conveying path 2 may not be set. It can be understood that there can be a large gap between two adjacent variable-pitch conveyor lines 21 in this section, and the flash spray assembly 6 can be set on the machine base 1 at the gap. This not only simplifies the structure of the first conveying path 2 and saves on structure, but also realizes the rational use of machine base space.

[0045] Furthermore, the first conveying path 2 may also include follower wheels 23, blocking elements 25, and sensors 24. The follower wheels 23, blocking elements 25, and sensors 24 can all cooperate with the variable-pitch conveyor line 21. Taking any set of variable-pitch conveyor lines 21 as an example, the follower wheels 23 are evenly distributed on both sides of the variable-pitch conveyor line 21. The variable-pitch conveyor line 21 can adjust the width of adjacent belts according to the width of the workpiece. The follower wheels 23 on both sides move together with the belts; that is, as the width between the two belts is adjusted, the distance between the follower wheels 23 on both sides also changes, so that the distance between the follower wheels 23 on both sides can just accommodate... The workpiece passes through the conveyor belt, and the follower wheel 23 guides its transmission on the variable-pitch conveyor line 21, preventing deviation and excessive resistance during transport. A sensor 24 is located at the input end of the variable-pitch conveyor line 21, and a blocking member 25 is located at its output end. The sensor 24 senses the position of the workpiece on the conveyor line 21. When the workpiece reaches the preset position, the belt stops, and the blocking member 25 positions and blocks the workpiece, facilitating precise gripping by the material handling mechanism 7. The specific structures of the variable-pitch conveyor line 21 and the roller conveyor line 22 are existing technologies and will not be described in detail here.

[0046] In an embodiment, such as Figure 3 As shown, the second conveying path 3 may include a reciprocating conveyor line 31 and a carrier 32. The carrier 32 is fixedly mounted at the drive end of the reciprocating conveyor line 31. The reciprocating conveyor line 31 can drive the carrier 32 to reciprocate along the X direction. The carrier 32 serves to support and clamp the workpiece to be processed, preventing the workpiece from shifting in position due to vibration or other reasons during the conveying process, and avoiding misprinting during the printing process. The reciprocating conveyor line 31 may include a linear motor module, the specific structure of which is prior art and will not be described in detail.

[0047] Preferably, the reciprocating conveyor line 31 is located below the table surface of the machine tool 1, which can be understood as the reciprocating conveyor line 31 being located inside the cavity of the machine tool 1. The table surface of the machine tool 1 has a clearance opening that can cover the entire reciprocating conveyor line 31. Furthermore, the carrier 32 is height-adjustable in the Z-direction, meaning that within the travel range of the reciprocating conveyor line 31, the carrier 32 carrying the workpiece can pass through the clearance opening. Because the reciprocating conveyor line 31 is located inside the cavity of the machine tool 1, the carrier 32 has greater height adjustment space without increasing the height of the inkjet mechanism 5, thus not increasing the overall height of the UV inkjet equipment. The height-adjustable design of the carrier 32 allows the inkjet equipment to accommodate workpieces of different sizes.

[0048] Specifically, such as Figure 4 As shown, the carrier 32 includes a first driving member 321, a second driving member 322, a gripper assembly 323, and an elastic component 324. The first driving member 321 is disposed at the driving end of the reciprocating conveyor line 31. The driving end of the first driving member 321 is provided with two mounting plates 325. The first driving member 321 can drive the two mounting plates 325 to move closer or further away from each other simultaneously. The second driving member 322, the gripper assembly 323, and the elastic component 324 are all disposed based on the two mounting plates 325. The first driving member 321 can be understood as a clamping cylinder, which utilizes the principle of screw drive. However, compared to a clamping cylinder, its stroke is more controllable and its application range is wider. Of course, in other embodiments, the first driving member 321 may also include a clamping cylinder or two linear motors. There is no limitation here, as long as it can drive the two mounting plates 325 to move closer or further away from each other simultaneously.

[0049] The two mounting plates 325 have the same structure and the components installed on them are also the same. Here, we will take one of the mounting plates 325 as an example for explanation. The second driving member 322 is installed on the mounting plate 53, the gripper assembly 323 is installed on the driving end of the second driving member 322, and the elastic member 324 is installed on the gripper assembly 323.

[0050] Specifically, the gripper assembly 323 includes a connecting portion 3233 and mutually perpendicular support portions 3231 and blocking portions 3232. The connecting portion 3233 is connected to the driving end of the second driving member 322, the blocking portion 3232 is fixedly connected to the connecting portion 3233, and the support portion 3231 is vertically connected to the blocking portion 3232. The support portion 3231 is used to support the workpiece to be processed. The two blocking portions 3232 can clamp and fix the workpiece to be processed by squeezing it. Preferably, the blocking portion 3232 is provided with a clearance notch. The clearance notch divides the blocking portion into several blocking parts to avoid the gripping end of the material transfer mechanism 7 (which will be further explained later when describing the structure of the material transfer mechanism 7), thus avoiding interference with the material transfer mechanism 7's transfer of the workpiece to be processed.

[0051] Furthermore, an elastic component 324 is disposed on the support portion 3231. This elastic component 324 includes an elastic element 3241, a lifting rod 3242, and a rubber pad 3243. The support portion 3231 has a groove, within which the lifting rod 3242 and the elastic element 3241 are located. The lifting rod 3242 has a convex cross-section along the Z-direction, with the smaller diameter portion extending deep into the groove. The elastic element 3241 is fitted onto the smaller diameter portion of the lifting rod 3242. The rubber pad 3243 is located at the other end of the lifting rod 3242. When the workpiece is placed on the support portion 3231, it first contacts the rubber pad 3243, compressing the elastic element 3241 to absorb product deformation and ensure a flat upper surface of the workpiece. In this embodiment, the elastic element 3241 can be a spring.

[0052] In an embodiment, such as Figure 6 As shown, the surface treatment mechanism 4 includes a column 41, a longitudinal transfer module 42, and a plasma head 43. The column 41 is mounted on the machine base 1, specifically located on one side of the material receiving end of the first conveying path 2. The longitudinal transfer module 42 is mounted on the column 41, and the plasma head 43 is located at the drive end of the longitudinal transfer module 42. The working end of the plasma head 43 is located directly above the variable pitch conveyor line 21. The longitudinal transfer module 42 can drive the plasma head 43 to move in the Z direction to adapt to workpieces of different heights. When the workpiece is received, the surface treatment mechanism 4 first performs surface treatment on the workpiece, and then performs the next inkjet treatment to improve the inkjet quality of the workpiece.

[0053] In an embodiment, such as Figure 5As shown, the material transfer mechanism 7 includes two sets. One set of material transfer mechanisms 7 transports the workpiece to be processed from the first conveyor path 2 to the second conveyor path 3, while the other set transports the workpiece to be processed after inkjet printing from the second conveyor path 3 to the first conveyor path 2. One set is located on the machine base 1 adjacent to the surface treatment mechanism 4. After the workpiece has undergone surface treatment, this set of material transfer mechanisms transports the workpiece from the first conveyor path 2 to the second conveyor path 3. The other set of material transfer mechanisms 7 is located on the machine base 1 between the inkjet printing mechanism 5 and the quality inspection mechanism 8. This set of material transfer mechanisms 7 transports the inkjet-printed workpiece located on the second conveyor path 3 to the first conveyor path 2. The structure of one set of material transfer mechanisms 7 will be described below as an example.

[0054] Any material handling mechanism 7 may include a first gantry 71, a first XZ moving module 72, a clamping drive 73, and a gripper plate 74. The first gantry 71 is mounted on the machine base 1 and is erected above the first conveying path 2 and the second conveying path 3. The first XZ moving module 72 is mounted on the first gantry 71. The clamping drive 73 is mounted on the drive end of the first XZ moving module 72. Two sets of gripper plates 74 are mounted on the drive end of the clamping drive 73. It should be noted that the gripper plates 74 are provided with clearance notches. One clearance notch is provided on one gripper plate 74, and one clearance notch divides the gripper plate 74 into two gripper plates. Each gripper plate can extend into the clearance notch. When the material handling mechanism 7 handles the workpiece to be processed, it can eliminate the possible interference of the carrier 32. The workpiece to be processed can be placed directly on the support part 3231 and then the gripping of the workpiece to be processed can be released. In the embodiment, the first XZ moving module 72 can drive the clamping drive 73 to move in the X and Z directions. It may include a servo module and a rodless cylinder. The clamping drive 73 includes a lead screw structure, both of which are existing technologies.

[0055] Of course, in other embodiments, a set of material handling mechanisms 7 can also be set up to realize the transfer of the workpiece between the first conveying path 2 and the second conveying path 3. The first XZ moving module 72 needs to be replaced by a three-axis drive module so that it can drive the clamping drive 73 to move in the X, Y and Z directions respectively. However, it should be emphasized that this requires eliminating the possible interference of the inkjet mechanism 5.

[0056] In an embodiment, such as Figure 7As shown, the inkjet mechanism 5 includes a second gantry 52, a second XZ moving module 52, a mounting plate 53, a vision module 54, an inkjet head 55, and a UV assembly 56. The second gantry 52 is mounted on the first conveying path 2 and the second conveying path 3. The second XZ moving module 52 is mounted on the second gantry 52. ​​The mounting plate 53 is mounted on the drive end of the second XZ moving module 52. The vision module 54, the inkjet head 55, and the UV assembly 56 are respectively mounted on the mounting plate 53. The second XZ moving module 52 mainly drives the vision module 54, the inkjet head 55, and the UV assembly 56 on the mounting plate 53 to move automatically during debugging and line changing. During inkjet printing, the second XZ moving module 52 does not perform any operation. It should be emphasized that the UV surface of the UV assembly 56 is higher than the inkjet surface of the inkjet head 55.

[0057] In this embodiment, the quality inspection mechanism 8 includes a support frame 81, an XY transverse module 82, a scanning module 83, a pushing module 84, and an NC flow line 85. The support frame 81 is mounted on the machine base 1, specifically located on one side of the roller conveyor line 22. The XY transverse module 82 and the scanning module 83 are mounted on the support frame 81, both located above the roller conveyor line 22. The scanning module 83 is mounted on the drive end of the XY transverse module, the pushing module 84 is mounted on one side of the roller conveyor line 22, and the NC flow line is mounted on the other side of the roller conveyor line 22.

[0058] After inkjet printing, the workpieces to be processed flow onto the roller conveyor line 22. The workpieces pass through the roller conveyor line 22 at a uniform speed. The scanning module 83 scans and inspects the workpieces. Qualified workpieces flow out from the roller conveyor. Unqualified products are pushed out of the roller conveyor line by the pushing module 84. The pushed unqualified products flow to the NG line 85.

[0059] Specifically, the XY transverse module 82 may include a KK module, which can drive the scanning module 83 to move along the X and Y directions respectively. The scanning module 83 may include a light source and a camera. The pusher module 84 includes a pusher drive and a pusher plate. The NG flow line 85 includes a receiving plate 853 and multiple sets of parallel and inclined flow bars 851. The flow bars 851 are not driven by power. By being inclined, the product is conveyed from one end of the NG flow line 85 to the other end. The receiving plate 853 connects the roller conveyor line 22 and the flow bars 851, so that the product can be transferred relatively stably from the roller conveyor line 22 to the NG flow line 85. It also includes a baffle plate 852 disposed around the flow bars 851. The baffle plate 852 is mainly used to prevent the product from sliding off the conveyor line composed of the flow bars 851.

[0060] The product (i.e., the part to be processed) flows from the previous workstation into the variable pitch conveyor line 21. After inkjet printing, the part to be processed is transported by the material transfer mechanism 7 to the carrier 32 on the second conveyor path 3. The product is positioned with the upper plane of the part to be processed as a reference. The carrier 32 clamps the product and the reciprocating conveyor line 31 drives the product through the inkjet mechanism 5 to perform inkjet printing and UV curing. During this process, the inkjet mechanism 5 remains stationary while the product moves to complete the inkjet printing. After the inkjet printing is completed, the carrier 32 releases the product, and the material transfer mechanism 7 transports the product to the first conveyor path 2. After the product is picked up, the reciprocating conveyor line 31 drives the carrier 32 back to the initial position (we refer to the position of the carrier 32 on the side of the feed end as the initial position). The product then flows to the roller conveyor line 22 for inkjet printing inspection. OK products flow to the next workstation, while NG products are pushed to the NG flow line 85 and manually removed.

[0061] The above description is merely a preferred embodiment of this application and does not limit the scope of protection of this application.
