Description

[0001] This application is a divisional application filed on March 26, 2020, with application number 202010225138.7, and entitled "A Dip Coating and Curing Production Line Using a Liquid Blowing Method to Clean Excess Coating Liquid". Technical Field

[0002] This invention relates to an dip coating and curing production line, and more particularly to an dip coating and curing production line and its operating method. Background Technology

[0003] Existing dip-coating and curing production lines generally lack versatility, cannot simultaneously accommodate products of different specifications and models, have low production efficiency, and fail to meet production requirements. Furthermore, existing dip-coating and curing production lines lack liquid blowing capabilities, which is inadequate for some products, such as urinary catheters, which have drainage holes 103. Figure 1 As shown in the figure, 101 is the excretion cone-shaped interface, 102 is the catheter body, and 103 is the excretion orifice. Therefore, when coating the product, coating liquid will enter the excretion orifice 103, and the existing carrier cannot conveniently drain the coating liquid from the excretion orifice 103.

[0004] In addition, some products, such as urinary catheters, require two coatings and curing processes, and each coating needs a certain amount of time to dry before curing. So the steps are: first coating, first drying, first curing, second coating, second drying, second curing.

[0005] Cycle requirements: First coating, first drying, first curing, second coating, second drying, second curing. The time cycle of the entire process needs to be strictly controlled, but the time required for each step is different. Therefore, the composition of the entire production line must consider the individuality of each step, the continuity of the entire production line, and the fact that the cycle time of each product is different. The cycle time parameters need to be adjusted in real time, which the existing dip coating and curing production line cannot accomplish.

[0006] Meanwhile, existing dip coating curing production lines have limited space for the curing chamber, and the curing light source cannot be turned off during production. Since the intense curing light is harmful to the human body, light leakage is unacceptable. However, curing chambers on the market use a single-door light-blocking method, requiring the door to be opened when the carrier is placed in or removed from the curing chamber, causing light leakage. Over time, this not only damages the equipment but also harms the health of the operators.

[0007] Therefore, considering the aforementioned technical problems, it is necessary to provide a new technical solution. Summary of the Invention

[0115] The present invention provides an impregnation and curing production line, comprising a carrier 20 and a machine body;

[0116] like Figure 4-8 As shown, the carrier 20 in this embodiment includes: a carrier plate 201 and one or more carrier shafts 205 mounted on the carrier plate 201, wherein the carrier shaft 205 has a through hole along its axial direction, and the product to be processed can be mounted on the carrier shaft 205; and a cover plate 202, which is engaged with the upper surface of the carrier plate 201, and has an air inlet 203. A receiving cavity is formed between the cover plate 202 and the carrier plate 201, and the receiving cavity communicates with the through hole and the air inlet 203 respectively; and a carrier shaft driving device 206, which drives the carrier shaft 205 to rotate, and the rotation of the carrier shaft 205 causes the product to be processed to rotate.

[0117] In this embodiment, a sealing gasket 213 is provided between the cover plate 202 and the upper surface of the carrier plate 201.

[0118] The carrier plate 201 has one or more mounting holes arranged in two staggered rows, and each mounting hole houses one carrier shaft 205. In this embodiment, 40 carrier shafts 205 are installed on the carrier plate 201, but other numbers are also possible. The carrier plate 201 has two rows of staggered mounting holes along its length, with 20 holes in each row, and each mounting hole houses one carrier shaft 205, for a total of 40 carrier shafts 205.

[0119] In this embodiment, each of the carrier shafts 205 is equipped with a rotating gear 208 and a bearing 209. The carrier shaft 205 is located above the bearing 209. When the carrier shaft 205 is installed in the mounting hole through the bearing 209, the rotating gear 208 is accommodated in the receiving cavity.

[0120] In this embodiment, in the two rows of rotating gears 208, one rotating gear 208 in one row meshes with one or two adjacent rotating gears 208 in the other row. When any one of the rotating gears 208 rotates, it will drive all the other rotating gears 208 to rotate.

[0121] In this embodiment, the carrier shaft drive device 206 is mounted on the cover plate 202. The carrier shaft drive device 206 drives the rotating gear 208 to rotate. When the carrier shaft drive device 206 drives the rotating gear 208 to rotate, it drives the carrier shaft 205 to rotate, which in turn drives the product to be processed mounted on the carrier shaft 205 to rotate. Preferably, the carrier shaft drive device 206 is a geared motor, which is mounted on the upper surface of the cover plate 202 at the middle position via a motor mounting plate 207. A shaft hole 204 is also provided at the corresponding position on the cover plate 202. One end of a carrier shaft 205 at the middle position passes through the rotating gear 208 and extends to the outside of the cover plate 202 through the shaft hole 204, and is installed in cooperation with the geared motor. When the carrier 20 is working, the geared motor can drive the carrier shaft 205 to rotate, which in turn drives the rotating gear 208 mounted on it to rotate, thereby driving all the carrier shafts 205 to rotate, and in turn driving all the products to be processed mounted on the carrier shafts 205 to rotate. Preferably, the cover plate 202 has two air inlets 203, which are located on both sides of the shaft hole 204 on the upper surface of the cover plate 202.

[0122] In this embodiment, the carrier 20 has a power probe on its carrier plate 201. The power probe is electrically connected to the carrier shaft drive device 206. In this embodiment, preferably, slots are opened at both ends of the lower surface of the carrier plate 201. The power probe consists of two conductive elements 210, which are respectively installed in the slots at one end of the carrier plate 201. The two conductive elements 210 are respectively electrically connected to the carrier shaft drive device 206. When the carrier 20 is placed on the corresponding workstation, the power probe on the carrier 20 contacts and connects with the power probe 626 described below, and is powered by an external power source. The carrier shaft drive device 206 then operates. In this way, the carrier 20 itself is not electrified and can safely load and unload materials.

[0123] In this embodiment, a first insulating element 211 is also provided between the two conductive elements 210 to separate the two conductive elements 210 and prevent electrical connection between the two conductive elements 210 during use, which would cause a short circuit in the entire circuit.

[0124] In this embodiment, a second insulating element 212 is also provided on the carrier plate 201. The second insulating element 212 is installed in the slot at the other end of the carrier plate 201. Preferably, the first insulating element 211 and the second insulating element 212 are both made of POM material.

[0125] In this embodiment, the fuselage has, along its positive x-axis direction, a first part 1, a second part 2, a third part 3, and a fourth part 4, as follows: Figure 2 and 3 As shown, the first part 1 and the third part 3 each include a coating device, and the second part 2 and the fourth part 4 each include one or more light curing chambers 60.

[0126] The first part 1 applies a first coating to the product to be treated; the second part 2 applies a first curing to the product to be treated that has already undergone the first coating; the third part 3 applies a second coating to the product to be treated that has already undergone the first curing; and the fourth part 4 applies a second curing to the product to be treated that has already undergone the second coating.

[0127] In the embodiment, the first part 1, the second part 2, the third part 3 and the fourth part 4 of the fuselage also include frames 8, adjacent frames 8 are connected by connectors 7, and an inner cavity is formed in the frame 8.

[0128] The coating device and the light curing chamber 60 are respectively mounted on the frame 8 and located inside the cavity of the frame 8, such as... Figure 9-11 As shown.

[0129] In this embodiment, the first part 1, the second part 2, the third part 3 and the fourth part 4 of the machine body also include a conveying device, the conveying device includes a conveyor line 30 and a robot arm 40, the conveyor line 30 and the robot arm 40 are respectively mounted on the frame 8;

[0130] Preferably, the second part 2 and the fourth part 4 each include one of the aforementioned light curing chambers 60;

[0131] In this process, the conveyor line 30 of the first part 1 drives the carrier 20 from the initial position to the first gripping position, and the robot arm 40 of the first part 1 drives the carrier 20 to move sequentially between the first gripping position, the first coating position and the first placement position. During this process, the coating device of the first part 1 completes the first coating of the product to be processed on the carrier 20.

[0132] The conveyor line 30 of the second part 2 drives the carrier 20 from the first placement position to the second gripping position. The robot arm 40 of the second part 2 drives the carrier 20 to move sequentially between the second gripping position, the first curing position and the second placement position. During this process, the light curing box 60 of the second part 2 completes the first curing of the product to be processed on the carrier 20.

[0133] The conveyor line 30 of the third part 3 drives the carrier 20 from the second placement position to the third gripping position. The robot arm 40 of the third part drives the carrier 20 to move sequentially between the third gripping position, the second coating position and the third placement position. During this process, the coating device of the third part 3 completes the second coating of the product to be processed on the carrier 20.

[0134] The fourth part 4 includes two conveyor lines 30. One conveyor line 30 drives the carrier 20 from the third placement position to the fourth gripping position. The robot arm 40 of the fourth part drives the carrier 20 to move sequentially between the fourth gripping position, the second curing position and the fourth placement position. During this process, the light curing box 60 of the fourth part completes the second curing of the product to be processed on the carrier 20. After that, the other conveyor line 30 of the fourth part 4 drives the carrier 20 to move from the fourth placement position to the material picking position.

[0135] In this embodiment, preferably, the second part 2 may further include two of the aforementioned light curing chambers 60.

[0136] In this process, the conveyor line 30 of the second part 2 drives the first carrier 20 from the first placement position to the second gripping position, and the robot arm 40 of the second part drives the first carrier 20 from the second gripping position to the first curing position. The light curing box 60 at the corresponding position performs the first curing on the product to be processed on the first carrier 20.

[0137] Then the robotic arm 40 of the second part 2 moves back and drives the second carrier 20 from the second gripping position to the third curing position, and another light curing box 60 at the corresponding position performs the first curing on the product to be processed on the second carrier 20;

[0138] Then, the robotic arm 40 of the second part 2 drives the first carrier 20 to move from the first curing position to the second placement position, then moves back and drives the third carrier 20 to move from the second gripping position to the first curing position, and the light curing box 60 at the corresponding position performs the first curing on the product to be processed on the third carrier 20.

[0139] Then, the robotic arm 40 of the second part 2 drives the second carrier 20 to move from the third curing position to the second placement position, then moves back and drives the fourth carrier 20 to move from the second gripping position to the third curing position. The other light curing box 60 at the corresponding position performs the first curing on the product to be processed on the fourth carrier 20. Then the previous actions are repeated until the first curing of all products is completed.

[0140] In this embodiment, preferably, the fourth part 4 may further include two of the aforementioned light curing chambers 60.

[0141] In this process, a conveyor line 30 of the fourth part 4 drives the first carrier 20 from the third placement position to the fourth gripping position, and the robot arm 40 of the fourth part 4 drives the first carrier 20 from the fourth gripping position to the second curing position. The light curing box 60 at the corresponding position performs a second curing on the product to be processed on the first carrier 20.

[0142] Then the robotic arm 40 of the fourth part 4 moves back and drives the second carrier 20 from the fourth gripping position to the fourth curing position, and another light curing box 60 at the corresponding position cures the product to be processed on the second carrier 20 for the second time.

[0143] Then, the robotic arm 40 of the fourth part 4 drives the first carrier 20 to move from the second curing position to the fourth placement position, then moves back and drives the third carrier 20 to move from the fourth gripping position to the second curing position, and the light curing box 60 at the corresponding position performs a second curing on the product to be processed on the third carrier;

[0144] Then, the robotic arm 40 of the fourth part 4 drives the second carrier 20 to move from the fourth curing position to the fourth placement position, then moves back and drives the fourth carrier 20 to move from the fourth gripping position to the fourth curing position. The other light curing box 60 at the corresponding position performs a second curing on the product to be processed on the fourth carrier 20. Then the previous actions are repeated until the second curing of all products is completed.

[0145] Of course, in this embodiment, the number of light curing boxes 60 in the second part 2 and the fourth part 4 is not limited to one or two, but can be other numbers, and the working order follows the same principle.

[0146] In this embodiment, the conveyor line 30 includes a drive belt 315 and a conveyor drive device 301, such as... Figure 12 As shown, the transmission belt 315 is located above the frame 8, and the carrier 20 is placed on the transmission belt 315; the conveyor line 30 also includes a conveyor mounting plate 304 and two conveyor side plates 303. The conveyor side plates 303 are vertically fixed to the upper surface of the frame 8 by the conveyor mounting plate 304, and the length direction of the conveyor side plates 303 is consistent with the x-axis direction of the frame 8. The two conveyor side plates 303 are symmetrically arranged along the y-axis direction of the frame 8, and there is a distance between the two conveyor side plates 303.

[0147] like Figure 12 As shown, in this embodiment, the conveying side plate 303 is preferably T-shaped, with its vertical end vertically installed on the upper surface of the conveying mounting plate 304, and the length direction of its horizontal end is consistent with the x-axis direction of the frame 8.

[0148] In this embodiment, multiple pulleys are respectively provided on the corresponding surfaces of the two conveying side plates 303. The pulleys are rotatably mounted on the conveying side plates 303 via driven shafts 307, and the pulleys on each conveying side plate 303 are connected by a transmission belt 315. The conveying drive device 301 drives the pulleys to rotate, thereby driving the transmission belt 315 to rotate. Preferably, each conveying plate uses 5 pulleys, of which two are located at the two ends of the horizontal end of the conveying side plate 303 as follower pulleys 309, two are located at the junction of the vertical end and the horizontal end of the conveying side plate 303, i.e., the waist, as tension pulleys 317, and the last one is installed at the vertical end as a synchronous pulley 308.

[0149] In this embodiment, the conveying side plate 303 is also provided with an adjustment groove 318, preferably located at the waist of the conveying side plate 303. A tensioning wheel 317 at the waist of the conveying side plate 303 is movably mounted on the adjustment groove 318. Adjusting the position of the tensioning wheel 317 on the adjustment groove 318 adjusts the tension of the transmission belt 315.

[0150] In this embodiment, the conveying drive device 301 preferably employs a geared motor and a drive shaft 305. The geared motor is mounted on the outer side of one of the conveying side plates 303, and the drive shaft 302 of the geared motor passes through the conveying side plate 303 and is connected to a synchronous pulley 308 mounted on the vertical end of the same conveying side plate 303. The geared motor drives the synchronous pulley 308 to rotate by controlling the rotation of the drive shaft 302. The two ends of the drive shaft 305 are respectively connected to the synchronous pulleys 308 at the vertical ends of the two conveying side plates 303 via couplings 306. When the synchronous pulley 308 driven by the geared motor rotates, the synchronous pulley 308 at the vertical end of the other conveying side plate 303 rotates through the drive shaft 305, thereby causing the two transmission belts 315 to operate synchronously.

[0151] Of course, the drive shaft 305 or the geared motor can also drive pulleys in other positions. However, this solution preferably uses pulleys installed at the vertical end of the conveyor side plate 303. This allows the conveyor line 30 to form a deep U-shape, ensuring that the carrier 20 will not collide during transmission. Synchronous transmission ensures that both ends of the carrier 20 are synchronized and stably positioned, while also keeping the equipment clean and reducing contamination from lubricating fluid. Furthermore, each conveyor line 30 has its own geared motor to control its own operating speed.

[0152] In this embodiment, at both ends of the horizontal end of the conveying side plate 303, as shown... Figure 12 As shown, the longer end is the input end, and the shorter end is the output end. However, the last conveyor line 30 in section 4 is installed in reverse, with the shorter end as the input end and the longer end as the output end, as shown... Figure 11 As shown.

[0153] In this embodiment, both the input and output ends of the conveyor side plate 303 are provided with a stop bar 310, a detection device 311, and a guide block 316. The stop bar 310 mainly serves to block at the input and output positions to allow the robot arm 40 time to react. In the preceding conveyor line 30 of the first part 1, the second part 2, the third part 3, and the fourth part 4, the input position of the conveyor side plate 303 is the placement position, and the output position is the gripping position. In the following conveyor line 30 of the fourth part 4, the input position of the conveyor side plate 303 is the placement position, and the output position is the material picking position. The detection device 311 preferably uses a photoelectric sensor to detect whether the carrier 20 is in position. When a carrier 20 is detected to have reached the gripping position, a control signal is transmitted to the robot arm 40. The guide block 316 mainly guides the movement of the carrier 20 on the conveyor line 30.

[0154] In this embodiment, longitudinal reinforcing ribs 313 are provided on both sides of the transmission belt 315 on the corresponding surface at the vertical end of the conveyor side plate 303. Simultaneously, transverse reinforcing ribs 312 are provided in the middle of the transmission belt 315 on the corresponding surface at the horizontal end, primarily to strengthen and stabilize the conveyor side plate 303. Furthermore, a transmission belt support strip 314 is provided below the transmission belt 315 to support it.

[0155] In this embodiment, the light curing box 60 includes a light fixing device 601, an external baffle 603, and an adjusting device 602, such as... Figure 13-19 As shown, the lighting fixing device 601 includes a fixing bracket 604 and at least one lighting unit. In this embodiment, four lighting units are preferred. The fixing bracket 604 has an inner cavity, and the four lighting units are installed sequentially in the inner cavity of the fixing bracket 604 along the y-axis direction of the frame 8.

[0156] The external baffle 603 engages with one side of the fixed bracket 604 and forms a curing cavity between itself and the fixed bracket 604, with the light irradiation direction of the light irradiation unit facing the curing cavity;

[0157] The adjustment device 602 is movably installed between the lighting fixing device 601 and the external baffle 603, and can be driven to move closer to or away from the lighting fixing device 601. The carrier 20 is installed on the adjustment device 602.

[0158] When the carrier 20 is installed on the adjustment device 602, the product to be processed is located in the curing chamber. The adjustment device 602 moves the product to be processed closer to or further away from the light-fixing device 601 as it approaches or moves away from the light-fixing unit.

[0159] In this embodiment, the light curing chamber 60 further includes a light-shielding drive device 611 and a light-shielding plate 608. Preferably, a first light-shielding connecting plate 609 is installed on the fixed bracket, and the light-shielding drive device 611 is installed on the first light-shielding connecting plate 609 through a second light-shielding connecting plate 610. The light-shielding drive device 611 is electrically connected to the electrical control box 9. The light-shielding plate 608 is located between the light unit and the curing chamber and is driven by the light-shielding drive device 611 to move in a light-shielding position and a non-light-shielding position.

[0160] During the curing process, the light-shielding plate 608 is driven to move to the non-shielding position, and the light emitted by the light-illuminating unit enters the curing chamber; after curing is completed, the light-shielding plate 608 is driven to move to the light-shielding position.

[0161] In this embodiment, the light curing chamber 60 further includes a partition 510 and a controller 617. Preferably, each light unit corresponds to one controller 617. The partition 510 divides the inner cavity of the fixed bracket 604 into a light chamber and a control chamber. The light unit is located in the light chamber, and the four controllers 617 are sequentially installed on the bottom plate 618 in the control chamber.

[0162] In this embodiment, the illumination unit includes a reflector 607 and a curing lamp 606 mounted on the reflector 607. Preferably, the curing lamp 606 is a mercury lamp, but other types of curing lamps can also be used. The reflector 607 is located within the illumination chamber, and the curing lamp 606 is electrically connected to the controller 617. The illumination direction of the curing lamp 606 is towards the product to be processed.

[0163] In this embodiment, the illumination unit further includes a filter 605, preferably a filter glass. The filter 605 is located between the curing lamp 606 and the product to be processed, and can filter out the ultraviolet light for curing to ensure the curing temperature.

[0164] In this embodiment, the light curing chamber 60 further includes a rear exhaust panel 615, a side light shield 613, a top light shield 614, a rear exhaust panel 616, and a dashboard 612.

[0165] The exhaust back plate 615 is installed on the long side of the light-irradiation chamber away from the curing chamber, and the exhaust back plate 615 is provided with exhaust holes, which can be connected to external exhaust fans and other exhaust equipment. On the one hand, the exhaust back plate 615 can block light, and on the other hand, it can also be used to dissipate heat for the curing lamp 606.

[0166] The side light shields 613 are respectively installed on the two wide sides of the light-illuminating chamber, and the top light shield 614 is installed on the top of the light-illuminating chamber to prevent the light from the curing lamp 606 from leaking out.

[0167] The exhaust rear plate 616 is installed on the long side of the control chamber away from the curing chamber, and an exhaust fan 630 is also installed on the exhaust rear plate 616. Preferably, four exhaust fans 630 are installed, and each exhaust fan 630 corresponds to a controller 617, which can dissipate heat from the controller 617.

[0168] The instrument panel 612 is mounted on two wide sides of the control chamber and is used to mount some instruments used in the equipment.

[0169] In this embodiment, the bottom of the outer baffle 603 is provided with at least one exhaust fan 630 mounting hole 628. Preferably, three exhaust fan mounting holes 628 are provided, and each exhaust fan 630 is installed in each exhaust fan mounting hole 628.

[0170] The curing chamber is also provided with an internal air inlet plate 627, which surrounds the exhaust fan mounting hole 628. The internal air inlet plate 627 is preferably in the shape of a vertical folded plate, and at least one air inlet 629 is provided on both the parallel and vertical surfaces of the internal air inlet plate 627. It is preferably provided with multiple thin strip-shaped long holes to ensure the ventilation effect of the equipment.

[0171] In this embodiment, the inner surfaces of the light-blocking plate 621 and the outer baffle 603, as well as the outer surface of the inner air intake plate 627, are each covered with a reflector of the same material as the reflector cover 607. This is mainly to uniformly reflect the light source onto the product to be processed, and also to protect the outer baffle 603 from deformation due to overheating.

[0172] In this embodiment, the adjustment device 602 includes an adjustment front plate 619, an adjustment rear plate 620, and a conductive block 623.

[0173] The front adjustment plate 619 and the rear adjustment plate 620 are arranged parallel to each other and are a certain distance apart. The height of the front adjustment plate 619 is greater than the height of the rear adjustment plate 620. The length of the front adjustment plate 619 is the same as the length of the rear adjustment plate 620. The upper surface of the front adjustment plate 619 is aligned with the upper surface of the rear adjustment plate 620.

[0174] The conductive block 623 is installed between the front adjustment plate 619 and the rear adjustment plate 620. One or two power probes 626 are provided on the conductive block 623, and the power probes 626 are connected to an external power source.

[0175] The conductive block 623 includes a first conductive block and a second conductive block. The distance between the first conductive block and the second conductive block is less than the length of the carrier plate 201. When the carrier 20 is installed, one power probe 626 is connected to one conductive element 210. The two conductive elements 210 on the carrier 20 are at the same end. Each conductive block 623 has two power probes 626. When the carrier 20 is installed on the adjustment device 602, the two conductive elements 210 on the carrier 20 are connected to the two power probes 626 of one conductive block 623 to conduct electricity, while the two power probes 626 on the other conductive block 623 are connected to the second insulating element 212 on the carrier 20. The two power probes 626 are disconnected and not energized.

[0176] Similarly, the two conductive elements 210 on the carrier 20 can also be at different ends. Each conductive block 623 is provided with a power probe 626. When the carrier 20 is installed on the adjustment device 602, the two conductive elements 210 on the carrier 20 are respectively connected to the two power probes 626 for power supply. With the above structure, the carrier 20 can be installed on the adjustment device 602 in any direction, regardless of whether the two conductive elements 210 on the carrier 20 are at the same end or at different ends. Therefore, when placing the carrier 20, the operator does not need to identify the placement direction of the carrier 20, saving time and effort and production time.

[0177] In this embodiment, the conductive block 623 is preferably a rectangular block, and the upper surface of the conductive block 623 is recessed downwards. The power probe 626 is located in the recess on the upper surface of the conductive block 623. The conductive block 623 also includes an insulating plate 624 and an insulating sleeve 625.

[0178] The insulating plate 624 is installed in the recess on the upper surface of the conductive block 623, and the shape of the insulating plate 624 is consistent with the shape of the recess on the upper surface of the conductive block 623, such as... Figure 19 As shown. The insulating plate 624 has an insulating hole corresponding to the position of the power probe 626. The power probe 626 is located in the insulating hole, and the height of the power probe 626 is greater than the thickness of the insulating plate 624. This can better ensure that the power probe 626 contacts the conductive element 210 when the carrier 20 is installed.

[0179] The insulating sleeve 625 is fitted between the power probe 626 and the inner wall of the insulating hole.

[0180] like Figure 13 and 17 As shown, in this embodiment, the upper ends of both sides of the outer baffle 603 are bent inward horizontally to form two elongated planes. The adjusting device 602 is installed between the light source fixing module and the outer baffle 603. Two conductive blocks 623 are placed on the two elongated planes respectively, and the conductive blocks 623 can slide on the elongated planes. In use, the distance between the adjusting device 602 and the curing lamp 606 can be adjusted back and forth according to the intensity of the curing lamp 606. Because the light intensity of the curing lamp 606 is strong in the early stage, the position of the adjusting device 602 and the curing lamp 606 will be relatively far apart. As the service life increases, the light intensity of the curing lamp 606 will be relatively weaker. At this time, the distance between the adjusting device 602 and the curing lamp 606 should be brought closer to ensure the stability of curing.

[0181] In this embodiment, the adjustment device 602 further includes a light-blocking plate 621, which is vertically installed on the outer surface of the adjustment rear plate 620 and is parallel and aligned with the lower surface of the adjustment rear plate 620. This ensures that no matter how the position of the adjustment device 602 is moved, the light from the curing lamp 606 will not leak out from the top of the light curing box 60.

[0182] In this embodiment, the adjustment device 602 further includes a detection device 311, preferably a photoelectric sensor, such as... Figure 17 As shown, preferably, a mounting bracket 622 is installed on the outer surface of the conductive block 623. The mounting bracket 622 is in the shape of a bent plate. The detection device 311 is fixed on the mounting bracket 622 and is used to detect whether there is a carrier 20 on the adjustment device 602. The detection device 311 is electrically connected to the electrical control box 9.

[0183] In this embodiment, when the carrier 20 is installed on the adjustment device 602, after the detection device 311 detects that the carrier 20 is installed in place, the electrical control box 9 controls the light-shielding drive device 611 to drive the light-shielding plate 608 to open. At the same time, the conductive element 210 is in contact with the power probe 626, and the carrier shaft drive device 206 drives the carrier shaft 205 to rotate so as to drive the product to be processed to rotate. The curing lamp 606 can evenly irradiate the rotating product to be processed.

[0184] In this embodiment, the robotic arm 40 includes a horizontal drive device, a vertical drive device, and a robotic gripper 407. The robotic arm 40 is mounted on the upper surface of the frame 8 via a robotic arm base plate 401. The horizontal drive device is fixed above the frame 8 by two support columns 402. The horizontal drive device includes an x-axis slide rail 403 and a horizontal drive motor 404, as well as a horizontal slide plate. The horizontal drive motor 404 can drive the horizontal slide plate to slide on the x-axis slide rail 403. The vertical drive device is mounted on the horizontal slide plate, and when the horizontal drive motor 404 drives the horizontal slide plate to move, the vertical drive device moves along with it. The vertical drive device includes a vertical drive motor 405 and a z-axis slide rail 406, as well as a robotic gripper mounting plate. The robotic gripper 407 is mounted on the robotic gripper mounting plate, and the vertical drive motor 405 drives the robotic gripper mounting plate to move on the z-axis slide rail 406, thereby causing the robotic gripper 407 to move vertically. The robotic arm 40 is mainly used to transport the carrier 20 to perform coating or curing operations. The robotic arm 40 has the characteristics of stable gripping of the carrier 20, precise positioning, and high efficiency.

[0185] In this embodiment, the mechanical gripper 407 includes grippers 409 and gripper drive device 408. Preferably, there are two sets of grippers 409, each set including two grippers 409. Each set of grippers 409 is driven by a gripper drive device 408. The gripper drive device 408 drives the grippers 409 to clamp or release the carrier 20. The gripper drive device 408 is preferably a cylinder. The two grippers 409 in each set are respectively mounted on the cylinder. The cylinder drives the two grippers 409 to move closer or further apart.

[0186] In this embodiment, the mechanical claw 407 further includes a claw mounting plate 413 and at least one air inlet 410. The claw driving device 408 and the air inlet 410 are respectively mounted on the claw mounting plate 413. Preferably, the two air inlets 410 are spaced apart along the length of the claw mounting plate 413, and the positions of the two air inlets 410 correspond to the positions of the two air inlets 203 on the cover plate 202 of the carrier 20. When the mechanical claw 407 grips the carrier 20, the air inlets 410 communicate with the external gas through the air inlets 410.

[0187] In this embodiment, the gas inlet 410 is tubular and vertically mounted on the gripper mounting plate 413. The diameter of one end of the gas inlet 410 is larger than the diameter of the other end. The gas inlet 410 is mounted on the gripper mounting plate 413 through its smaller diameter end, and passes through the gripper mounting plate 413. A silicone sealing ring 412 is also installed on the larger diameter end of the gas inlet 410. The silicone ring is hollow, ensuring that gas can enter. When the robotic arm 40 picks up the carrier 20, the air inlet 410 connects to the air inlet 203. The silicone sealing ring 412 can effectively seal the air and prevent gas leakage. At the same time, a spring 411 is also sleeved on the small-diameter end of the air inlet 410 below the carrier 20. When the robotic arm 40 picks up the carrier 20, the spring 411 can apply an elastic force to the air inlet 410, which can better ensure that the silicone sealing ring 412 is tightly attached to the upper surface of the carrier plate 201, and better ensure the sealing performance of the silicone sealing ring 412.

[0188] In this embodiment, the first part 1 and the third part 3 of the machine body also include a liquid blowing tank 80, which is respectively installed on the frame 8 and located in the inner cavity of the frame 8;

[0189] In this process, the robotic arm 40 of the first part 1 drives the carrier 20 to move from the first coating position to the first liquid blowing position. Then, external gas enters the receiving cavity through the air inlet 410 and the air inlet 203 and passes through the through hole to complete the first liquid blowing on the product to be treated. After that, the robotic arm 40 of the first part 1 drives the carrier 20 to move from the first liquid blowing position to the first placement position.

[0190] The robotic arm 40 of the third part 3 drives the carrier 20 to move from the second coating position to the second liquid blowing position. Then, external gas enters the receiving cavity again through the air inlet 203 and passes through the through hole to complete the second liquid blowing on the product to be treated. After that, the robotic arm 40 of the third part 3 drives the carrier 20 to move from the second liquid blowing position to the third placement position.

[0191] In this embodiment, the coating device includes a coating tank 50, a coating tank mounting plate 501, a coating tank cover plate 502, a cover plate driving device 509, a partition plate 510, and a pressurizing device 504.

[0192] The coating tank 50 is mounted on the frame 8 via the coating tank mounting plate 501. Preferably, the coating tank 50 is mounted on the coating tank mounting plate 501 via the coating tank hanging plate 506, and the open end of the coating tank 50 passes through the coating tank mounting plate 501 by a certain distance.

[0193] The coating tank cover 502 engages with the opening of the coating tank 50, and the cover driving device 509 drives the coating tank cover 502 to cover or expose the opening of the coating tank 50. Preferably, the coating tank cover 502 is a cover-shaped structure with an opening on its long side. Figure 22 As shown, the lower left corner of the coating tank cover plate 502 is an opening. When coating is required, the cover plate driving device 509 drives the coating tank cover plate 502 to move along the width direction of the coating tank mounting plate 501, i.e., the upper right corner direction in the figure, and the coating tank 50 protrudes from under the coating tank cover plate 502. Similarly, when coating is not required, the coating tank cover plate 502 returns to the shielded position, covering the coating tank 50. In this embodiment, it is preferable to provide a coating tank cover plate baffle 503 at the edge of the coating tank 50, such as... Figure 22 As shown, when the coating tank cover plate 502 returns to the shielding position and covers the coating tank 50, the opening of the coating tank cover plate 502 is just closed by the coating tank cover plate baffle 503. This can better completely shield the coating tank 50 and effectively prevent the evaporation of the coating liquid in the coating tank 50.

[0194] The partition 510 divides the inner cavity of the coating tank 50 into a liquid storage cavity 512 and a coating cavity 511, and the height of the partition 510 is less than the height of the coating tank 50. During coating, the product to be treated is located in the coating cavity 511. Preferably, connection holes are provided at the bottom of the liquid storage cavity 512 and the coating cavity 511 of the coating tank 50, respectively.

[0195] One end of a three-way connector 513 is connected to the connection hole at the bottom of the coating cavity 511. The connection hole at the bottom of the liquid storage cavity 512 is connected to a booster device 504, preferably a booster pump. The booster pump and the other end of the three-way connector 513 are connected through a pipe 507 to connect the liquid storage cavity 512 and the coating cavity 511. At the same time, in order to prevent the coating liquid in the coating cavity 511 from flowing back into the liquid storage cavity 512, a check valve 505 is also added in this embodiment. Preferably a check valve is used. The highest liquid level of the coating liquid in the coating cavity 511 is not higher than the height of the partition 510. The coating liquid higher than the partition 510 will automatically flow into the liquid storage cavity 512.

[0196] In this embodiment, a liquid level detection device (not shown in the figure) is provided in both the coating cavity 511 and the liquid storage cavity 512 to detect the liquid level. Preferably, a liquid level detection switch is used. When the liquid level in the coating cavity 511 or the liquid storage cavity 512 reaches the set minimum value, it will remind you to add liquid. In addition, if liquid needs to be added to the coating cavity 511, the booster pump is turned on to add the liquid from the liquid storage cavity 512 into the coating cavity 511. This has the advantage of avoiding the liquid at the bottom from being unused and prone to quality changes. We can use the booster pump to circulate the liquid, which can avoid waste of the liquid and make full use of it. Similarly, when cleaning, clean water is added to the coating cavity 511 or the liquid storage cavity 512 in the coating tank 50, and the booster pump is used to circulate for a period of time to rinse the waste liquid in the coating tank 50. Finally, the wastewater is discharged through the drain pipe 508, thereby achieving the purpose of cleaning. It is not necessary to remove the coating tank 50 for cleaning, which is simple, convenient and quick.

[0197] In this embodiment, the coating tank 50 is preferably made of Teflon material, but other materials can also be used to ensure that the coating solution can be maintained in the coating tank 50 for a long time.

[0198] This embodiment of the dip coating curing production line also includes a housing 5, a touch screen 6, and at least one electrical control box 9, preferably four curing boxes, with two installed in the inner cavity of the frame 8 of the first part 1 and the third part 3 respectively. Of course, the position of the electrical control boxes 9 of the entire dip coating curing production line is not fixed; they can be installed in other locations, and the number is not limited. The position and number of electrical control boxes 9 of the entire dip coating curing production line can be adjusted appropriately as needed. The above is only a preferred embodiment. In this embodiment, all the electrical control boxes 9 are interconnected and jointly control the entire dip coating curing production line. Of course, each electrical control box 9 can also individually control one or more parts, individually control one or more devices in the same or different parts, or one or more can control the same part together, etc.

[0199] The electrical control box 9 is electrically connected to the touch screen 6. The electrical control box 9 controls the operation of the dip coating and curing production line, and the touch screen 6 monitors data and sets parameters for the entire system.

[0200] In addition, this device can coat and cure any product. Urinary catheters and sheaths are just one type. It can coat and cure surface coatings on strip-shaped or tubular objects with slender structures, such as urinary catheters and sheaths.

[0201] The specific implementation steps are as follows:

[0202] (a) Preparation stage for coating:

[0203] Adding liquid: Manually add an appropriate amount of coating liquid into the coating cavity and the liquid storage cavity of the coating tank.

[0204] Catheter loading: Attach one end of the catheter's discharge cone-shaped interface to the carrier, and let the other end hang down naturally. Complete the installation of the catheters in sequence.

[0205] (II) Four-part cyclical operation phase

[0206] S1: First application and blowing of liquid onto the catheter (part 1)

[0207] Press the start button on the touch screen to start the device. Manually place the first carrier containing the catheter into the input end of the first section of the conveyor line. After the photoelectric sensor at the input end detects the carrier, the conveyor line moves to output the carrier forward until the photoelectric sensor at the output end detects the carrier, at which point the conveyor line stops moving and the baffle at the output end blocks the carrier. At this point, the first robotic arm moves to a safe position directly above the first carrier, and moves it to the coating tank. The cover drive extends the coating tank cover, removing it from the tank. The robotic arm continues to descend with the carrier, ensuring the entire portion of the catheter to be coated is submerged in the tank for the first coating. After coating, the first robotic arm lifts the carrier to a safe height, removing the catheter from the tank for drying. The cover drive retracts the cover, closing it to prevent evaporation. Simultaneously, the first robotic arm moves the carrier to a set blowing height directly above the blowing tank, placing the catheter into the tank. Air from the air inlet enters the catheter through the carrier shaft, blowing out the coating solution from the drainage hole. The first robotic arm then lifts the carrier to the input end of the second conveyor line, and repeats the above steps to coat the catheter on the next carrier.

[0208] S2: The second part is the first curing of the urinary catheter.

[0209] Once the photoelectric sensor at the input end of the second-section conveyor line detects the carrier, the second-section conveyor line moves forward, outputting the carrier until the photoelectric sensor at the output end detects the carrier. At this point, the second-section conveyor line stops, and the baffle at the output end blocks the carrier (the time from when the carrier leaves the coating tank of the first section until the output end of the second-section conveyor line is the first drying time). The robotic arm of the second section moves directly above the carrier, grasps it, and moves it directly above one of the light-curing chambers in the second section, placing the carrier on the adjusting device. The power probe on the carrier detects the power probe on the adjusting device and automatically connects the power supply, controlling the carrier shaft drive to operate at the specified speed, thereby causing the entire carrier shaft to rotate. Simultaneously, the light-shielding drive device retracts the light-shielding plate, allowing the curing lamp to evenly illuminate the rotating catheter for curing. While the first carrier is curing, the second robotic arm picks up the next carrier from the second conveyor line and places it on another photocuring box in the second section. It then cures the carrier following the same steps as the first. While the second carrier is curing, the first carrier completes curing. The second robotic arm then picks up the first carrier and places it at the input end of the third conveyor line. It then moves to the output end of the second conveyor line to pick up the third carrier and places it on the previous photocuring box in the second section. The catheter on the third carrier is cured following the same steps. Simultaneously, the catheter on the second carrier completes curing, and the second robotic arm picks up the second carrier and places it at the input end of the second conveyor line. The second robotic arm repeats this process cyclically.

[0210] At any moment during the solidification of the second part, the first part is also operating synchronously according to the steps of S1.

[0211] S3: The third part is the second coating and blowing of the catheter.

[0212] When the first carrier is detected at the output end of the third-section conveyor line, the robotic arm of the third section moves to a safe position directly above the first carrier and moves it to the coating tank of the third section. The cover drive device extends the coating tank cover, causing it to leave the coating tank. The robotic arm continues to descend with the first carrier, allowing the entire portion of the catheter to be coated to be inserted into the coating tank for a second coating. After coating, the robotic arm of the third section raises the first carrier to a set safe height, allowing the catheter to leave the coating tank for drying. The cover drive device retracts the coating tank cover, covering the coating tank to prevent the coating liquid from evaporating. Simultaneously, the robotic arm of the third section moves the first carrier to a set blowing height directly above the blowing tank of the third section, placing the catheter on the first carrier into the blowing tank of the third section. Air from the air inlet enters the catheter through the carrier shaft, blowing out the coating liquid that entered the catheter's discharge hole. The robotic arm in the third part grabs the first carrier and lifts it upwards, placing the carrier at the input end of the previous conveyor line in the fourth part. Then, the robotic arm in the third part repeats the above steps to coat the catheters on the next carrier (the second carrier, the third carrier, and so on).

[0213] At any point during the third part of the dipping and blowing process, the first and second parts are also operating synchronously according to steps S1 and S2.

[0214] S4: The fourth part is the second curing of the urinary catheter.

[0215] Once the photoelectric sensor at the input end of the preceding conveyor line in the fourth section detects the carrier, the preceding conveyor line in the fourth section moves forward to output the carrier until the photoelectric sensor at the output end detects the carrier. At this point, the preceding conveyor line in the fourth section stops moving, and the baffle at the output end blocks the carrier (the time from when the carrier leaves the coating tank in the third section to the output end of the preceding conveyor line in the fourth section is the second drying time). The robotic arm in the fourth section moves directly above the first carrier, grabs it, and moves it directly above a light-curing box in the fourth section, placing the carrier on the adjusting device. The power probe on the first carrier detects the power probe on the adjusting device and automatically connects the power supply, controlling the carrier shaft drive to operate at the specified speed, thereby causing the entire carrier shaft to rotate. Simultaneously, the light-shielding drive... The light shield retracts, allowing the curing lamp to evenly illuminate the rotating catheter for curing. While the first carrier is curing, the robotic arm in the fourth section picks up the next carrier from the previous conveyor line in the fourth section and places it on another light curing box in the fourth section. It then follows the same curing steps as the first carrier. While the second carrier is curing, the first carrier is cured. The robotic arm in the fourth section then picks up the first carrier and places it at the input end of another conveyor line in the fourth section. Sensors at the input and output ends of the other conveyor line in the fourth section detect the first carrier and send it out. The other conveyor line in the fourth section stops moving when the output sensor detects the first carrier, and a stop bar blocks the movement of the first carrier. The first carrier can then be manually removed, and the cured catheter can be taken off. Meanwhile, after placing the first carrier on another conveyor line in the fourth section, the robotic arm in the fourth section moves to the output end of the previous conveyor line in the fourth section to grab the third carrier that has been transported there. It places the carrier on the previous light curing box in the fourth section and cures the catheter on the third carrier according to the steps described above. While the catheter on the third carrier is curing, the catheter on the second carrier is also curing. The robotic arm in the fourth section then grabs the second carrier and places it on the input end of another conveyor line in the fourth section, ready to be transported out. The robotic arm in the fourth section repeats the above steps in a cyclical manner.

[0216] At any moment when the fourth part is solidified, the first, second, and third parts are also operating synchronously according to steps S1, S2, and S3, and so on, with the four parts working in a cycle as described above.
