[0067] Example 1

[0068] like Figure 1-2 As shown, embodiment 1 of the present invention provides a fully automated UV marking inkjet printer, which includes a frame 10, a dust cover 20 covering the frame 10, a vibration feeding mechanism 30, and a receiving mechanism 70. The frame 10 is provided with a servo mechanism 11, and the frame 10 is provided with a material taking component 12, a transfer component 13, a two-way side spraying mechanism 14, a UV curing mechanism 15, a shearing visual rejection mechanism 16 and a discharge mechanism 17 for processing a heart stent guide tube 80 in sequence along the direction from the front end to the rear end of the servo mechanism 11. The front end of the dust cover 20 is provided with a plasma processing mechanism 21, as shown in FIG. Figure 6The plasma processing mechanism 21 is placed between the material taking component 12 and the transfer component 13. The vibration feeding mechanism 30 is arranged at the front end of the frame 10 for conveying the heart stent guide tube 80 to be processed to the material taking component 12. The receiving mechanism 70 is arranged at the rear end of the frame 10 for collecting the heart stent guide tube 80 output by the unloading mechanism 17. The present invention reduces the intensity of manual transfer of products and improves the efficiency of conveying by arranging a servo mechanism 11 on the frame 10 to facilitate the assembly line conveyance of the heart stent guide tube 80. In addition, the material taking component 12 is sequentially arranged on the frame 10. , transfer component 13, two-way side spray mechanism 14, UV curing mechanism 15, shearing visual rejection mechanism 16 and unloading mechanism 17, so that the heart stent guide tube 80 passing through the above mechanism is gradually processed, and the processing order is loading, plasma treatment, transfer, coding, UV curing, cutting, rejection and unloading. The equipment integrates multiple functions in one. The use of this equipment can effectively improve the production efficiency of the heart stent guide tube 80 and reduce the skill requirements for the staff. At the same time, since the automated equipment replaces manual production, the labor intensity of the staff is indirectly reduced.

[0069] Please refer to Figure 2 and Figure 3 In some embodiments of the present invention, the servo mechanism 11 includes a first servo component 111 and a second servo component 112 arranged parallel to the frame 10, the orthographic projection of the first servo component 111 in the direction of the second servo component 112 overlaps with at least part of the second servo component 112, and the first servo component 111 and the second servo component 112 are both provided with a pin assembly 113 for loading the heart stent guide tube 80.

[0070] Specifically, the material picking component 12 is arranged at the front end of the first servo component 111, and the transfer component 13 is mounted above the first servo component 111 and the second servo component 112, wherein the ejector component 113 is movably arranged on the first servo component 111 or the second servo component 112, so that the transfer component 13 can realize the transfer and replacement of the ejector components 113 on the first servo component 111 and the second servo component 112, thereby ensuring that the ejector component 113 on the first servo component 111 can return to one end of the material picking component 12 to continue loading, and the ejector component 113 placed on the second servo component 112 can drive the heart stent guide tube 80 to perform coding, UV curing, cutting, rejection and unloading processes.

[0071] like Figure 4As shown, in some embodiments of the present invention, the material picking component 12 includes a first stand 1201 and a transition air pipe 1203, wherein the first stand 1201 is arranged on the side of the front end of the first servo component 111 to avoid affecting the operation of the ejector assembly 113 on the first servo component 111, and the transition air pipe 1203 is arranged at the upper end of the first stand 1201. In order to meet the transportation requirements, a support frame 1202 is provided at the upper end of the first stand 1201, and the transition air pipe 1203 is arranged on the support frame 1202. The feed end of the transition air pipe 1203 is connected with the discharge end of the vibrating feeding mechanism 30, so that the heart stent guide tube 80 to be processed enters through the feed end of the transition air pipe 1203 and is sent out from the discharge end of the transition air pipe 1203.

[0072] In addition, in order to be able to take out the heart stent guide tube 80 to be processed from the discharge end of the transition air pipe 1203 and transfer it to the ejector assembly 113, the material taking assembly 12 also includes a first rotary cylinder 1208, which needs to be set at the lower end of the first stand 1201, and also needs to be installed with a rotating arm 1209 on the first rotary cylinder 1208, and the rotating arm 1209 is provided with a second pneumatic clamp 1210; wherein, the second pneumatic clamp 1210 and the rotating arm 1209 are in a state of rotation. In coordination, when the rotating arm 1209 swings upward, the second pneumatic clamp 1210 rotates to the discharge end of the transition air pipe 1203 and clamps one of the heart stent guide tubes 80. Then the rotating arm 1209 reverses and swings downward. At this time, the heart stent guide tube 80 changes from a horizontal state to a vertical state, thereby putting the heart stent guide tube 80 on the ejector assembly 113. Repeat the above actions until the ejector assembly 113 is full of heart stent guide tubes 80. After it is full, it can be transferred to the next process through the first servo assembly 111.

[0073] It should be noted that, since the heart stent guide tube 80 to be processed is continuously moved toward the transition air pipe 1203 under the action of the vibrating feeding mechanism 30, in order to avoid the problem that the next heart stent guide tube 80 to be processed is pushed out of the transition air pipe 1203 and falls after the second pneumatic clamp 1210 takes the material, the material taking component 12 also includes a blocking cylinder 1205, wherein a stopper 1206 is provided on the piston rod of the blocking cylinder 1205, and the stopper 1206 can extend to the discharge end of the transition air pipe 1203, so that after the second pneumatic clamp 1210 takes the material, the stopper 1206 can block the discharge end of the transition air pipe 1203 to avoid the heart stent guide tube 80 to be processed from falling.

[0074] Since the heart stent guide tubes 80 to be processed are stacked in the transition air pipe 1203, in order to avoid the second pneumatic clamp 1210 taking multiple heart stent guide tubes at the same time when taking materials, which may lead to defective products in subsequent processing, the material taking component 12 also includes a first pneumatic clamp 1204, wherein the first pneumatic clamp 1204 is arranged above the transition air pipe 1203. In order to achieve the above purpose, it is necessary to open a clamping window near the discharge end of the transition air pipe 1203, so that when the second pneumatic clamp 1210 takes materials, the first pneumatic clamp 1204 can clamp the next heart stent guide tube 80 to be processed through the clamping window, ensuring that the previous heart stent guide tube 80 to be processed will not overlap when clamped, thereby ensuring the subsequent processing quality.

[0075] In some embodiments of the present invention, since the stop block 1206 can extend to the discharge end of the transition air pipe 1203, in order to avoid movement interference between the second pneumatic clamp 1210 and the stop block 1206, it is necessary to provide a material collection window at the discharge end of the transition air pipe 1203 so that the second pneumatic clamp 1210 can clamp the heart stent guide tube 80 to be processed from the material collection window when the rotating arm 1209 swings upward.

[0076] In other embodiments of the present invention, since the heart stent guide tube 80 to be processed has a certain length, after the second pneumatic clamp 1210 clamps the heart stent guide tube 80 to be processed through the material picking window, in order to further avoid the interference of movement between the second pneumatic clamp 1210 and the stopper 1206, a first lifting cylinder 1207 is provided on the first stand 1201, and the first rotary cylinder 1208 is arranged at the piston end of the first lifting cylinder 1207, so that the second pneumatic clamp 1210 can avoid the position of the stopper 1206 when the rotating arm 1209 is swung up. Specifically, after the second pneumatic clamp 1210 is swung up to a vertical state with the rotating arm 1209, the first lifting cylinder 1207 acts to move the second pneumatic clamp 1210 so that the second pneumatic clamp 1210 can clamp the heart stent guide tube 80 to be processed.

[0077] Please combine Figure 5To understand this embodiment, the transfer assembly 13 includes a second stand 1301, a conversion plate 1304 and a third pneumatic clamp 1305, wherein the conversion plate 1304 is rotatably arranged on the second stand 1301, and the third pneumatic clamp 1305 is symmetrically arranged at both ends of the conversion plate 1304, and the third pneumatic clamps 1305 at both ends are respectively placed above the first servo assembly 111 and the second servo assembly 112. When the conversion plate 1304 rotates, the third pneumatic clamps 1305 at both ends of the conversion plate 1304 are swapped. At this time, the ejector assembly 113 on the first servo assembly 111 is interchanged with the ejector assembly 113 on the second servo assembly 112. The unloaded ejector assembly 113 returns to the material taking assembly 12 with the first servo assembly 111 to continue taking materials, while the fully loaded ejector assembly 113 is transported to the next process with the second servo assembly 112.

[0078] Specifically, a second lifting cylinder 1302 is provided on the second stand 1301, and a second rotary cylinder 1303 is provided on the piston end of the second lifting cylinder 1302. The conversion plate 1304 is installed at the output end of the second rotary cylinder 1303. The third pneumatic clamp 1305 can be lifted by the second lifting cylinder 1302, thereby lifting the ejector assembly 113 clamped by the third pneumatic clamp 1305. During the rotation of the second rotary cylinder 1303, there will be no interference in the movement, thereby ensuring the efficiency of the conversion and improving production efficiency.

[0079] In other embodiments, in order to facilitate the third pneumatic clamping jaw 1305 to clamp the ejector assembly 113 , a groove for the third pneumatic clamping jaw 1305 to clamp should be provided on the ejector assembly 113 .

[0080] During the interchange between the ejector assembly on the first servo assembly 111 and the ejector assembly on the second servo assembly 112, in order to ensure that the fully loaded ejector assembly 113 can enter the next process for processing in the same flat state and reduce processing errors, a flattening member 1306 can be provided on the conversion plate 1304 so that the flattening member 1306 can be used to flatten the heart stent guide tube 80 to be processed on the ejector assembly 113.

[0081] like Figure 2 In this embodiment, the bidirectional side spray mechanism 14, UV curing mechanism 15, shearing visual rejection mechanism 16 and unloading mechanism 17 are sequentially arranged from the front end to the rear end along the length direction of the second servo assembly 112.

[0082] Please refer to Figure 7 and Figure 8In some embodiments of the present invention, the bidirectional side spray mechanism 14 includes a lifting assembly 1403 symmetrically arranged on both sides of the second servo assembly 112, and a translation assembly 1406 is installed on the lifting assembly 1403, wherein the translation assembly 1406 is provided with a side spray assembly 1405 facing the side of the second servo assembly 112. In addition, the lifting assembly 1403 and the translation assembly 1406 can be manual or electric. The function of both is to be able to adjust the position of the side spray assembly 1405 in the horizontal plane and the vertical plane to be suitable for the processing of heart stent guide tubes 80 of different lengths.

[0083] In other preferred embodiments, an ink cartridge assembly 1404 for supplying ink to the side spray assembly 1405 is further provided on the top of the lifting assembly 1403, and the side spray assembly 1405 is connected to the side spray assembly 1405 by a pipeline.

[0084] In addition, in order to meet the needs of automation, the bidirectional side spray mechanism 14 includes a third stand 1401 arranged on the frame 10, and the third stand 1401 is provided with a side spray trigger optical fiber sensor 1402 for detecting the heart stent guide tube 80.

[0085] It should be noted that the side spray trigger fiber optic sensor 1402 should be placed at the front end of the side spray assembly 1405, so that when the side spray trigger fiber optic sensor 1402 detects the heart stent guide tube 80, the side spray assembly 1405 is started to print.

[0086] like Figure 9 As shown, after printing, the printed part needs to be effectively and quickly cured, so the UV curing mechanism 15 is arranged at the rear end of the two-way side spray mechanism 14, and its function is to UV cure the heart stent guide tube 80 after printing, so as to facilitate the next step. The UV curing mechanism 15 includes a lampshade 1501 and a UV lamp group 1502 arranged inside the lampshade 1501, wherein the UV lamp group 1502 is two groups and is arranged relative to each other. When the heart stent guide tube 80 passes through the UV curing mechanism 15 along with the ejector pin assembly 113, the heart stent guide tube 80 can be placed between the two groups of UV lamp groups 1502, thereby ensuring that the printed part is effectively and quickly cured.

[0087] Please combine Figure 10In a specific embodiment of the present invention, the cutting visual rejection mechanism 16 includes a shield 161, a cutting assembly 163 and a visual rejection assembly 164. Specifically, the shield 161 is provided on the frame 10 to prevent the cutting assembly 163 from ejecting when cutting the heart stent guide tube 80. A recovery hopper 162 is provided below the shield 161 to recycle the cut scraps and rejected NG products. The cutting assembly 163 is provided on the inner side of the shield 161 to cut the heart stent guide tube 80 on the ejector assembly 113, wherein the visual rejection assembly 164 is used to reject NG products into the recovery hopper 162, and the visual rejection assembly 164 is provided at the rear end of the cutting assembly 163 to facilitate the rejection of NG products after cutting, thereby avoiding the need for repeated visual inspection, improving the flexibility and coordination of the assembly line, and improving the processing efficiency of the heart stent guide tube 80.

[0088] In some embodiments of the present invention, please refer to Figure 11 The cutting assembly 163 includes a fourth stand 1631 and pneumatic scissors 1636. Since the pneumatic scissors 1636 need to move up and down to cut the top of each heart stent guide tube 80 during the cutting process, a motor 1632 is provided on the fourth stand 1631, and a screw 1633 is provided at the output end of the motor 1632. In addition, in order to meet the up and down movement of the pneumatic scissors 1636, a first slide rail 1634 is also provided on the fourth stand 1631, and a screw slider 1635 is installed on the first slide rail 1634, and the screw slider 1635 is threadedly connected to the screw 1633. The pneumatic scissors 1636 are then installed on the screw slider 1635 to ensure the up and down movement of the pneumatic scissors 1636.

[0089] In addition, in the above example, in order to meet the up and down movement of the pneumatic scissors 1636, a cylinder combined with a slide rail can also be used. This method is a common technology in the machining field and will not be repeated here.

[0090] Reference Figure 12 After printing and cutting, the visual rejection component 164 needs to be used to reject NG products. Therefore, the visual rejection component 164 includes a fifth stand 1641, and a visual camera 1645 is set on the fifth stand 1641 to obtain images of the heart stent guide tube 80, so as to determine whether the heart stent guide tube 80 is an NG product. If it is an NG product, the heart stent guide tube 80 should be rejected. The rejection step is to remove the NG product from the ejector pin assembly 113 and place it in the recovery lower hopper 162.

[0091] In order to achieve the rejection of NG products, the visual rejection component 164 also includes a transverse cylinder 1642 arranged on the fifth stand 1641, and a third lifting cylinder 1643 is provided on the transverse cylinder 1642. A pneumatic rejection clamp 1644 is provided at the bottom end of the third lifting cylinder 1643. During rejection, the transverse cylinder 1642 drives the third lifting cylinder 1643 to extend above the heart stent guide tube 80, and the third lifting cylinder 1643 is actuated to lower the pneumatic rejection clamp 1644, so that the pneumatic rejection clamp 1644 can remove the corresponding heart stent guide tube 80 from the ejector assembly 113.

[0092] In addition, in order for the visual camera 1645 to clearly obtain the image information of the heart stent guide tube 80, a light source cover 1646 is also provided on the fifth stand 1641 to provide fill light for the heart stent guide tube 80 to ensure the accuracy of the removal.

[0093] Combine Figure 13 To understand this embodiment, after removing the NG products, the ejector assembly 113 transfers the OK products to the unloading mechanism 17 and then starts unloading. The unloading steps are as follows: the OK products are removed by the unloading mechanism 17 and placed on the receiving mechanism 70. In order to achieve the above-mentioned action, the unloading mechanism 17 includes a sixth stand 1701. The sixth stand 1701 is provided with a fourth lifting cylinder 1704. A blanking pneumatic clamp 1705 is installed at the piston end of the fourth lifting cylinder 1704. The height of the blanking pneumatic clamp 1705 is adjusted by the fourth lifting cylinder 1704. The blanking pneumatic clamp 1705 can be used to take out the OK products transferred by the ejector assembly 113.

[0094] Specifically, in order to meet the unloading needs of heart stent guide tubes 80 of different specifications, a linear cylinder 1702 and a second slide rail 1703 are also provided on the sixth stand 1701. At this time, the fourth lifting cylinder 1704 is slidably installed on the second slide rail 1703, and the outer shell of the fourth lifting cylinder 1704 is connected to the piston end of the linear cylinder 1702, so that the linear cylinder 1702 can drive the blanking pneumatic clamp 1705 to translate in the horizontal direction, thereby meeting the unloading needs of products of different specifications.

[0095] In addition, in order to allow the heart stent guide tube 80 to fall onto the material receiving mechanism 70 after unloading, a material drop chute 1706 is provided below the sixth stand 1701 , and the heart stent guide tube 80 is transported to the material receiving mechanism 70 through the material drop chute 1706 .

[0096] Furthermore, in order to improve the efficiency of unloading and collecting materials, the collecting mechanism 70 includes a conveyor belt and a plurality of bottles arranged on the conveyor belt, so as to facilitate packaging while unloading. During packaging, the material chute 1706 needs to be able to move to change the position of the discharge. A material distribution cylinder 1707 can be set on the frame 10 to push the material chute 1706, thereby changing the position of the discharge to meet the switching of the bottling position.

[0097] In addition, in order to achieve automatic control, the equipment also includes an operation center industrial control system 40, a UV inkjet coding control system 50 and a visual inspection control system 60. The servo mechanism 11, the vibration loading mechanism 30, the plasma processing mechanism 21, the material picking component 12, the transfer component 13 and the unloading mechanism 17 are all controlled by the operation center industrial control system 40, the two-way side spraying mechanism 14 and the UV curing mechanism 15 are controlled by the UV inkjet coding control system 50, and the visual rejection component 164 is controlled by the visual inspection control system 60.

[0098] The working process of the present invention is:

[0099] Start: First, place the heart stent guide tube 80 to be processed on the vibrating loading mechanism 30, and start the operation center industrial control system 40, UV inkjet control system 50 and visual inspection control system 60 to put the entire equipment into working condition;

[0100] Material collection: reference Figure 1-5 as well as Figure 15 The heart stent guide tubes 80 to be processed are stacked and transported to the transition air pipe 1203 in sequence under the action of the vibrating feeding mechanism 30. The blocking cylinder 1205 extends to push the block 1206 to the discharge end of the transition air pipe 1203 to prevent the first heart stent guide tube 80 to be processed from falling. At this time, the first pneumatic clamp 1204 moves to clamp the second heart stent guide tube 80 to be processed to avoid overlapping of materials. At this time, the first rotary cylinder 1208 drives the rotating arm 1209 to rotate upward to a vertical state, and the first lifting cylinder 12 07 action pushes the second pneumatic clamp 1210 upward so that the second pneumatic clamp 1210 can clamp the first heart stent guide tube 80 to be processed. At this time, the blocking cylinder 1205 acts to retract the block 1206, and the first rotary cylinder 1208 drives the rotating arm 1209 to rotate downward to a horizontal state. In this process, the heart stent guide tube 80 to be processed clamped by the second pneumatic clamp 1210 is sleeved on the ejector assembly 113. The above action is repeated until the ejector assembly 113 is filled with the heart stent guide tube 80, and then the next step is performed.

[0101] Transfer (plasma treatment): See Figure 6 and Figure 16The ejector assembly 113 fully loaded with the heart stent guide tube 80 moves along the first servo assembly 111 under the drive of the first servo assembly 111. During this process, the heart stent guide tube 80 is cleaned by the plasma treatment mechanism 21. When the ejector assembly 113 on the first servo assembly 111 and the second servo assembly 112 is placed under the transfer assembly 13, the second lifting cylinder 1302 is actuated to lower the third pneumatic clamp 1305 until the third pneumatic clamp 1305 is able to clamp the ejector assembly 113. After the third pneumatic clamp 1305 clamps the ejector assembly 113, the second rotary cylinder 1303 rotates 180 degrees, thereby replacing the positions of the ejector assemblies 113 on the first servo assembly 111 and the second servo assembly 112. That is, the fully loaded ejector assembly 113 is exchanged to the second servo assembly 112, and the unloaded ejector assembly 113 is exchanged to the first servo assembly 111, and then proceeds to the next process.

[0102] Inkjet printing: refer to Figure 7 、 Figure 8 as well as Figure 17 When the fully loaded ejector assembly 113 moves to the side spray trigger optical fiber sensor 1402 along with the second servo assembly 112, the side spray trigger optical fiber sensor 1402 senses and triggers the side spray assembly 1405 to print on the heart stent guide tube 80, and proceeds to the next process;

[0103] UV curing: refer to Figure 9 as well as Figure 17 After the printed heart stent guide tube 80 moves to the UV curing mechanism 15, the UV lamp group 1502 cures the printed part, and the cured heart stent guide tube 80 enters the shearing visual rejection mechanism 16 to the next process;

[0104] Cut: Reference Figure 10 、 Figure 11 as well as Figure 17 The motor 1632 drives the screw slider 1635 to rise or fall through the screw rod 1633. When cutting, the pneumatic scissors 1636 fall along with the screw slider 1635, so that the pneumatic scissors 1636 can cut the heart stent guide tube 80. After the cutting is completed, the pneumatic scissors 1636 need to be lifted by the motor 1632 to cut the next heart stent guide tube 80 and proceed to the next process.

[0105] Eliminate: Reference Figure 12 as well as Figure 17The cut heart stent guide tube 80 is photographed and identified by the visual camera 1645, which mainly identifies whether the printing and cutting meet the processing requirements. If they meet the processing requirements, they are OK products, otherwise they are NG products. At this time, the transverse cylinder 1642 drives the third lifting cylinder 1643 to extend above the heart stent guide tube 80. The third lifting cylinder 1643 drives the pneumatic rejection claw 1644 to descend and clamp the NG products, and reject the NG products into the recycling hopper 162. The OK products are moved to the unloading mechanism 17 along with the ejector assembly 113 to the next process;

[0106] Unloading: Refer to Figure 13 as well as Figure 17 During unloading, the linear cylinder 1702 contracts so that the pneumatic clamp 1705 is centered, and then the fourth lifting cylinder 1704 drives the pneumatic clamp 1705 to descend and clamp the heart stent guide tube 80 on the ejector assembly 113. Then, the fourth lifting cylinder 1704 drives the pneumatic clamp 1705 to rise, and the linear cylinder 1702 extends so that the pneumatic clamp 1705 moves to the top of the blanking chute 1706. After the pneumatic clamp 1705 is released, the heart stent guide tube 80 enters the blanking chute 1706, and the blanking chute 1706 can be driven to move by the dividing cylinder 1707 to meet the bottling requirements. After unloading, the ejector assembly 113 returns to the bottom of the transfer assembly 13 and continues to be replaced with the fully loaded transfer assembly 13 on the first servo assembly 111. Repeating the above steps can achieve uninterrupted processing.

[0107] In summary, the embodiment of the present invention provides a fully automated UV marking coding equipment, which reduces the intensity of manual transfer of products and improves the efficiency of transportation by arranging a servo mechanism 11 on the frame 10 to facilitate the assembly line transportation of the heart stent guide tube 80. In addition, the material picking component 12, the transfer component 13, the two-way side spray mechanism 14, the UV curing mechanism 15, the shearing visual rejection mechanism 16 and the unloading mechanism 17 are sequentially arranged on the frame 10, so that the heart stent guide tube 80 passing through the above-mentioned mechanisms is gradually processed, and the processing order is loading, plasma treatment, transfer, coding, UV curing, cutting, rejection and unloading. The equipment integrates multiple functions in one. The use of the equipment can effectively improve the production efficiency of the heart stent guide tube 80 and reduce the skill requirements for the staff. At the same time, since the automated equipment replaces manual production, the labor intensity of the staff is indirectly reduced.
