Description

Technical Field

[0001] The present invention relates to a dip coating and curing production line, and in particular to a dip coating and curing production line which adopts a liquid blowing method to clean excess coating liquid. Background Art

[0002] The existing dip coating and curing production line is generally not versatile and cannot be compatible with products of different specifications and models at the same time. The production efficiency is low and cannot meet the production requirements. At the same time, the existing dip coating and curing production line does not have the function of blowing liquid. For some products such as catheters, which have drainage holes 103, such as Figure 1 As shown in the figure, 101 is the drainage cone interface, 102 is the tube body of the catheter, and 103 is the drainage hole. Therefore, when coating the product, coating liquid will enter the drainage hole 103, and the existing carrier cannot more conveniently discharge the coating liquid in the drainage hole 103.

[0003] In addition, some products, such as catheters, need to be coated and cured twice, and each coating requires a certain amount of time to dry before curing, so the steps are: first coating, first drying, first curing, second coating, second drying, and second curing.

[0004] The tempo requirements are: first coating, first drying, first curing, second coating, second drying, and second curing. The tempo of the entire process needs to be strictly controlled. However, the time required for each step is different. Therefore, the composition of the entire production line must take into account both the individuality of each step and the continuity of the production actions of the entire production line. In addition, considering that the tempo of each product is different, the tempo parameters must be adjusted in real time, which is impossible with the existing dip coating and curing production line.

[0005] Existing dip-coating and curing lines also have limited space for curing chambers, and the curing light source cannot be turned off during production. Because the intense curing light is harmful to the human body, light leakage is essential. However, existing curing chambers on the market use a single-door light-blocking system. This door needs to be open when placing a carrier in or out of the chamber, allowing light to leak out. This prolonged operation not only harms the equipment but also the operator's health.

[0006] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a new technical solution. Summary of the Invention

[0098] The present invention provides a dip coating and curing production line for cleaning excess coating liquid by blowing liquid, comprising a carrier 20 and a body;

[0099] like Figure 4-8 As shown, the carrier 20 of this embodiment includes: a carrier plate 201 and one or more carrier shafts 205 installed on the carrier plate 201, the carrier shaft 205 is provided with a through hole along its axial direction, and the product to be processed can be installed on the carrier shaft 205; and a cover plate 202, the cover plate 202 is engaged with the upper surface of the carrier plate 201, the cover plate 202 is provided with an air inlet 203, and an accommodating cavity is formed between the cover plate 202 and the carrier plate 201, and the accommodating cavity is respectively connected to the through hole and the air inlet 203; and a carrier shaft driving device 206, the carrier shaft driving device 206 drives the carrier shaft 205 to rotate, and the rotation of the carrier shaft 205 drives the product to be processed to rotate.

In this way, the carrier 20 itself is not electrified and can load and unload materials safely.

[0106] In this embodiment, a first insulating element 211 is further 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, thereby preventing the entire circuit from being short-circuited.

[0107] In this embodiment, a second insulating element 212 is further provided on the carrier 201 . The second insulating element 212 is installed in a notch at the other end of the carrier 201 . Preferably, both the first insulating element 211 and the second insulating element 212 are made of POM.

The light curing box 60 at the corresponding position performs the first curing on the product to be processed on the third carrier 20;

[0122] Afterwards, the robot 40 of the second part 2 drives the second carrier 20 from the third curing position to the second placement position, and then moves back and drives the fourth carrier 20 from the second clamping position to the third curing position. Another light curing box 60 at the corresponding position performs the first curing on the product to be processed on the fourth carrier 20, and then repeats the previous action until the first curing of all products is completed.

[0127] Afterwards, the robot 40 of the fourth part 4 drives the second carrier 20 from the fourth curing position to the fourth placement position, and then moves back and drives the fourth carrier 20 from the fourth clamping position to the fourth curing position. Another light curing box 60 at the corresponding position performs a second curing on the product to be processed on the fourth carrier 20, and then repeats the previous action until the second curing of all products is completed.

[0128] Of course, in this embodiment, the number of the light curing boxes 60 of the second part 2 and the fourth part 4 is not limited to one or two, and can also be other numbers, and the working sequence is similar.

[0129] In this embodiment, the conveying line 30 includes a transmission belt 315 and a conveying drive device 301. Figure 12As 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 conveying mounting plate 304 and two conveying side plates 303, and the conveying side plates 303 are vertically fixed to the upper surface of the frame 8 through the conveying mounting plate 304, and the length direction of the conveying side plates 303 is consistent with the x-axis direction of the frame 8, and the two conveying side plates 303 are symmetrically arranged along the y-axis direction of the frame 8, and there is a distance between the two conveying side plates 303.

[0130] like Figure 12 As shown, in this embodiment, the conveying side plate 303 is preferably T-shaped, with its vertical end vertically mounted 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.

[0131] In this embodiment, a plurality of 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. 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, which in turn drives the transmission belt 315. Preferably, each conveying plate has five pulleys, two of which are located at the ends of the horizontal ends of the conveying side plates 303 as follower pulleys 309, two more located at the intersection of the vertical and horizontal ends of the conveying side plates 303, i.e., at the waist, as tensioning pulleys 317, and the last one is mounted at the vertical end and serves as a synchronous pulley 308.

[0132] In this embodiment, an adjustment groove 318 is also provided on the conveying side plate 303, preferably at the waist of the conveying side plate 303. A tensioning wheel 317 at the waist of the conveying side plate 303 is movably installed on the adjustment groove 318. The position of the tensioning wheel 317 on the adjustment groove 318 is adjusted to adjust the tightness of the transmission belt 315.

[0133] In this embodiment, the conveying drive device 301 preferably comprises a reduction motor and a transmission shaft 305. The reduction motor is mounted on the outer side of one of the conveying side plates 303, and the driving shaft 302 of the reduction motor passes through the conveying side plate 303 and is connected to a synchronous pulley 308 mounted at a vertical end of the same conveying side plate 303. The reduction motor drives the synchronous pulley 308 by controlling the rotation of the driving shaft 302. The ends of the transmission 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 reduction motor rotates, the synchronous pulley 308 at the vertical end of the other conveying side plate 303 rotates through the transmission shaft 305, thereby causing the two transmission belts 315 to operate synchronously.

[0134] Of course, the drive shaft 305 or reduction motor can also drive pulleys in other locations, but in this solution, the pulleys are preferably installed at the vertical ends of the conveyor side plates 303. This allows the conveyor line 30 to form a deep U-shape, ensuring that the carriers 20 do not collide during transportation. Synchronous transmission ensures that both ends of the carrier 20 are synchronized and positioned smoothly, while also keeping the equipment clean and reducing contamination from lubricating fluids. Furthermore, each conveyor line 30 has a separate reduction motor to control its own operating speed.

[0135] In this embodiment, at both ends of the horizontal end of the conveying side plate 303, Figure 12 As shown, the longer end is the input end and the shorter end is the output end. The last conveyor line 30 of the fourth part 4 is installed in reverse, with the shorter end as the input end and the longer end as the output end. Figure 11 shown.

[0136] In this embodiment, a baffle 310, a detection device 311, and a guide block 316 are further provided at both the input and output ends of the conveying side plate 303; the baffle 310 mainly serves as a barrier at the input and output positions to give the manipulator 40 time to react. In the first part 1, the second part 2, the third part 3, and the first conveyor line 30 of the fourth part 4, the input position of the conveying side plate 303 is the placement position, and the output position is the clamping position, while in the last conveyor line 30 of the fourth part 4, the input position of the conveying 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 place, and when it detects that a carrier 20 has reached the clamping position, it transmits a control signal to the manipulator 40. The guide block 316 mainly serves to guide the movement of the carrier 20 on the conveyor line 30.

[0137] In this embodiment, longitudinal reinforcing ribs 313 are provided on both sides of the transmission belt 315 on the surfaces corresponding to the vertical ends of the conveying side plates 303. Meanwhile, transverse reinforcing ribs 312 are provided in the middle of the transmission belt 315 on the surfaces corresponding to the horizontal ends, primarily to strengthen and stabilize the conveying side plates 303. Furthermore, a transmission belt support bar 314 is provided below the transmission belt 315 to provide support for the transmission belt 315.

[0138] In this embodiment, the light curing box 60 includes a light fixing device 601, an external baffle 603 and an adjustment device 602. Figure 13-19 As shown, the lighting fixture 601 includes a fixing bracket 604 and at least one lighting unit. In this embodiment, four lighting units are preferably provided. The fixing bracket 604 has an inner cavity. The four lighting units are sequentially installed in the inner cavity of the fixing bracket 604 along the y-axis direction of the frame 8.

[0139] The external baffle 603 is engaged with one side of the fixing bracket 604 and forms a curing cavity between the external baffle 603 and the fixing bracket 604. The illumination direction of the illumination unit is toward the curing cavity.

[0140] The adjusting device 602 is movably installed between the lighting fixture 601 and the external baffle 603 and can be driven to move closer to or away from the lighting fixture 601. The carrier 20 is installed on the adjusting device 602.

[0141] When the carrier 20 is mounted on the adjusting device 602 , the product to be processed is located in the curing chamber, and the adjusting device 602 moves closer to or farther from the illumination fixture 601 , driving the product to be processed closer to or farther from the illumination unit.

[0142] In this embodiment, the light curing box 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 electric 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 between a light shielding position and a non-light shielding position.

[0143] During curing, the shading plate 608 is driven to move to the non-shading position, and the light emitted by the illumination unit enters the curing chamber; after curing is completed, the shading plate 608 is driven to move to the shading position.

[0144] In this embodiment, the light curing box 60 also includes a partition 510 and a controller 617. Preferably, each light unit corresponds to a 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 installed in sequence on the bottom plate 618 in the control chamber.

[0145] In this embodiment, the illumination unit includes a reflective lampshade 607 and a curing lamp 606 mounted on the reflective lampshade 607. Preferably, the curing lamp 606 is a mercury lamp, although other types of curing lamps 606 are also possible. The reflective lampshade 607 is located within the illumination chamber. The curing lamp 606 is electrically connected to the controller 617, and the curing lamp 606 directs the illumination toward the product to be treated.

[0146] 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 curing ultraviolet light to ensure the curing temperature.

[0147] In this embodiment, the light curing box 60 further includes an exhaust rear panel 615, side shading panels 613, a top shading panel 614, an exhaust rear panel 616 and a dashboard 612.

[0148] The exhaust rear plate 615 is installed on the long side of the illumination chamber away from the curing chamber, and an exhaust hole is opened on the exhaust rear plate 615, which can be connected to an external exhaust fan or other exhaust equipment. On the one hand, the exhaust rear plate 615 can block light, and on the other hand, it can also be used to dissipate heat for the curing lamp 606.

[0149] The side shading plates 613 are respectively installed on two wide sides of the lighting chamber, and the top shading plate 614 is installed on the top of the lighting chamber to prevent the light of the curing lamp 606 from leaking out.

[0150] 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 for the controller 617.

[0151] The instrument panels 612 are respectively installed on the two wide sides of the control chamber and are used to install some instruments used by the equipment.

[0152] In this embodiment, at least one exhaust fan 630 mounting hole 628 is opened at the bottom of the external baffle 603. Preferably, three exhaust fan mounting holes 628 are opened, and an exhaust fan 630 is installed in each exhaust fan mounting hole 628.

[0153] An internal air inlet plate 627 is also provided in the curing chamber, and the internal air inlet plate 627 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 the parallel surface and vertical surface of the internal air inlet plate 627. It is preferably composed of multiple thin strip-shaped long holes to ensure the ventilation effect of the equipment.

[0154] In this embodiment, a layer of reflective plate made of the same material as the reflective lampshade 607 is also attached to the inner surface of the light baffle 621 and the external baffle 603, as well as the outer surface of the internal air inlet plate 627. This is mainly to evenly reflect the light source onto the product to be processed, and to protect the external baffle 603 from deformation due to overheating.

[0155] In this embodiment, the adjustment device 602 includes an adjustment front plate 619, an adjustment rear plate 620 and a conductive block 623.

[0156] The front adjustment plate 619 is arranged parallel to the rear adjustment plate 620 with a certain distance therebetween. 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 consistent with the length of the rear adjustment plate 620. The upper end surface of the front adjustment plate 619 is aligned with the upper end surface of the rear adjustment plate 620.

[0157] The conductive block 623 is installed between the adjustment front plate 619 and the adjustment rear plate 620 . One or two power probes 626 are provided on the conductive block 623 . The power probes 626 are connected to an external power source.

[0158] The conductive block 623 includes a first conductive block and a second conductive block. The distance between the first and second conductive blocks is less than the length of the carrier 201. When the carrier 20 is installed, one power probe 626 contacts and connects with one of the conductive elements 210. The two conductive elements 210 on the carrier 20 are located at the same end. Each conductive block 623 is provided with two power probes 626. When the carrier 20 is installed on the adjustment device 602, the two conductive elements 210 on the carrier 20 contact and connect with the two power probes 626 of one of the conductive blocks 623, energizing the two conductive elements. The two power probes 626 on the other conductive block 623 contact and connect with the second insulating element 212 on the carrier 20, disconnecting the two power probes 626 from the circuit and not energizing the two conductive elements 210.

[0159] Similarly, the two conductive elements 210 on the carrier 20 can also be at different ends, and a power probe 626 is set on each conductive block 623. When the carrier 20 is installed on the adjustment device 602, the two conductive elements 210 on the carrier 20 are respectively in contact with the two power probes 626 and connected to power. With the above structure, regardless of whether the two conductive elements 210 on the carrier 20 are at the same end or different ends, the carrier 20 can be installed on the adjustment device 602 in any direction. Therefore, when placing the carrier 20, the operator does not need to identify the placement direction of the carrier 20, which saves time and effort and saves production time.

[0160] In this embodiment, the conductive block 623 is preferably a rectangular block, and the upper surface of the conductive block 623 is concave downward. The power probe 626 is located in the concave portion of the upper surface of the conductive block 623. The conductive block 623 further includes an insulating plate 624 and an insulating sleeve 625.

[0161] 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. Figure 19 The insulating plate 624 has an insulating hole at a position corresponding to 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 is in contact with the conductive element 210 when the carrier 20 is installed.

[0162] The insulating sleeve 625 is sleeved between the power probe 626 and the inner wall of the insulating hole.

[0163] like Figure 13 and 17 As shown, in this embodiment, the upper ends of both sides of the outer baffle 603 are bent horizontally inward to form two elongated flat surfaces. The adjustment device 602 is mounted between the light source mounting module and the outer baffle 603. Two conductive blocks 623 are placed on the two elongated flat surfaces, and the conductive blocks 623 can slide on the elongated flat surfaces. During use, the distance between the adjustment device 602 and the curing light 606 can be adjusted back and forth according to the intensity of the curing light 606. Due to the high light intensity of the curing light 606 at the beginning, the adjustment device 602 and the curing light 606 are positioned relatively far apart. As the curing light 606's light intensity decreases over its service life, the adjustment device 602 and the curing light 606 should be moved closer to ensure stable curing.

[0164] In this embodiment, the adjusting device 602 also includes a light baffle 621, which is vertically mounted on the outer surface of the adjusting rear plate 620, and the light baffle 621 is aligned parallel to the lower surface of the adjusting rear plate 620, thereby ensuring that no matter how the position of the adjusting device 602 is moved, the light of the curing lamp 606 will not leak out from the top of the light curing box 60.

[0165] In this embodiment, the regulating device 602 further includes a detecting device 311, which is 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, and 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.

[0166] In this embodiment, when the carrier 20 is installed on the adjusting device 602, the detection device 311 detects that the carrier 20 is installed in place, and the electrical control box 9 controls the shading drive device 611 to drive the shading 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 to drive the product to be processed to rotate. The curing light 606 can evenly illuminate the rotating product to be processed.

[0167] In this embodiment, the manipulator 40 includes a horizontal drive mechanism, a vertical drive mechanism, and a mechanical gripper 407. The manipulator 40 is mounted on the upper surface of a frame 8 via a manipulator base plate 401. The horizontal drive mechanism is secured above the frame 8 via two support columns 402. The horizontal drive mechanism includes an x-axis slide 403 and a horizontal drive motor 404. It also includes a horizontal slide. The horizontal drive motor 404 can drive the slide to slide on the x-axis slide 403. The vertical drive mechanism is mounted on the slide. When the horizontal drive motor 404 drives the slide, the vertical drive mechanism moves along with it. The vertical drive mechanism includes a vertical drive motor 405 and a z-axis slide 406. It also includes a mechanical gripper mounting plate. The mechanical gripper 407 is mounted on the mechanical gripper mounting plate. The vertical drive motor 405 drives the mechanical gripper mounting plate to move on the z-axis slide 406, thereby driving the mechanical gripper 407 to move vertically. The manipulator 40 is mainly used to carry the carrier 20 to achieve coating or curing operations. The manipulator 40 has the characteristics of stable clamping of the carrier 20, precise positioning, and high efficiency.

[0168] In this embodiment, the mechanical claw 407 includes a clamp 409 and a clamp driving device 408, preferably two groups of clamps 409, each group includes two clamps 409, and each group of clamps 409 is driven by a clamp driving device 408. The clamp driving device 408 drives the clamp 409 to clamp or release the carrier 20. The clamp driving device 408 preferably adopts a cylinder, and the two clamps 409 of each group are respectively installed on the cylinder, and the cylinder drives the two clamps 409 to move closer or farther away.

[0169] In this embodiment, the mechanical claw 407 also includes a gripper mounting plate 413 and at least one air connection head 410. The gripper drive device 408 and the air connection head 410 are respectively mounted on the gripper mounting plate 413. Preferably, the two air connection heads 410 are spaced apart along the length direction of the gripper mounting plate 413, and the positions of the two air connection heads 410 correspond to the positions of the two air inlet holes 203 on the cover plate 202 of the carrier 20. When the mechanical claw 407 grasps the carrier 20, the air connection head 410 is connected to the external gas through the air connection head 410.

[0170] In this embodiment, the gas connection head 410 is tubular and vertically mounted on the clamping jaw mounting plate 413. The diameter of one end of the gas connection head 410 is larger than the diameter of the other end. The gas connection head 410 is mounted on the clamping jaw mounting plate 413 via the small-diameter end and passes through the clamping jaw mounting plate 413. A hollow silicone sealing ring 412 is also mounted on the large-diameter end of the gas connection head 410 to ensure that gas can enter. When the manipulator 40 clamps the carrier 20, the air connecting head 410 is connected to the air inlet 203, and the silicone sealing ring 412 can play a good sealing role to prevent gas leakage. At the same time, a spring 411 is also provided on the small diameter end of the air connecting head 410 below the carrier 20. When the manipulator 40 clamps the carrier 20, the spring 411 can apply an elastic force to the air connecting head 410, which can better ensure that the silicone sealing ring 412 is tightly attached to the upper surface of the carrier 201, thereby better ensuring the sealing performance of the silicone sealing ring 412.

[0171] In this embodiment, the first portion 1 and the third portion 3 of the body further include a liquid blowing tank 80, respectively. The liquid blowing tank 80 is respectively mounted on the frame 8 and located in the inner cavity of the frame 8;

[0172] The manipulator 40 of the first part 1 drives the carrier 20 to move from the first coating position to the first liquid blowing position, and then the external air enters the accommodating chamber through the air connection head 410 and the air inlet 203 and passes through the through hole to complete the first liquid blowing of the product to be processed. Then, the manipulator 40 of the first part 1 drives the carrier 20 to move from the first liquid blowing position to the first placement position;

[0173] The manipulator 40 of the third part 3 drives the carrier 20 to move from the second coating position to the second blowing position, and then the external gas enters the accommodating cavity again through the air inlet 203 and passes through the through hole to complete the second blowing of the product to be processed, and then the manipulator 40 of the third part 3 drives the carrier 20 to move from the second blowing position to the third placement position.

[0174] 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;

[0175] The coating trough 50 is installed on the frame 8 through the coating trough mounting plate 501. Preferably, the coating trough 50 is installed on the coating trough mounting plate 501 through the coating trough hanging plate 506, and the open end of the coating trough 50 passes through the coating trough mounting plate 501 for a certain distance.

[0176] The coating tank cover plate 502 is engaged with the opening of the coating tank 50, and the cover plate driving device 509 drives the coating tank cover plate 502 to cover or expose the opening of the coating tank 50. Preferably, the coating tank cover plate 502 is a cover-shaped structure with an opening on a long side, such as Figure 22 As shown, the side of the coating slot cover plate 502 at the lower left corner is open. When coating is required, the cover plate driving device 509 drives the coating slot cover plate 502 to move along the width direction of the coating slot mounting plate 501, i.e., the upper right corner direction in the figure, and the coating slot 50 is exposed from under the coating slot cover plate 502. Similarly, when coating is not required, the coating slot cover plate 502 returns to the shielding position to shield the coating slot 50. In this embodiment, it is preferred to set a coating slot cover plate baffle 503 at the edge of the coating slot 50, as shown in FIG. Figure 22 As shown, when the coating tank cover 502 returns to the shielding position to shield the coating tank 50, the opening of the coating tank cover 502 is just closed by the coating tank cover baffle 503, which can better completely shield the coating tank 50 and effectively prevent the volatilization of the coating liquid in the coating tank 50.

[0177] 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 smaller 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 respectively opened at the bottom of the liquid storage cavity 512 and the coating cavity 511 of the coating tank 50.

[0178] One end of a three-way joint 513 is connected to the connecting hole at the bottom of the coating inner cavity 511, and the connecting hole at the bottom of the liquid storage inner cavity 512 is connected to the boosting device 504, preferably a boosting pump, and the boosting pump and the other end of the three-way joint 513 are connected through a pipe 507 to connect the liquid storage inner cavity 512 and the coating inner cavity 511. At the same time, in order to prevent the coating liquid in the coating inner cavity 511 from flowing back into the liquid storage inner cavity 512, a check device 505 is added in this embodiment, preferably a check valve, and the highest liquid level of the coating liquid in the coating inner cavity 511 is not higher than the height of the partition 510. The coating liquid above the partition 510 will automatically flow into the liquid storage inner cavity 512.

[0179] In this embodiment, a liquid level detection device (not shown in the figure) is provided in 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 coating 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 coating liquid in the liquid storage cavity 512 to the coating cavity 511. The advantage of this is that it prevents the coating liquid on the bottom from being unused and easily undergoing quality changes. We can recycle the liquid through the booster pump to avoid waste of coating liquid and make full use of the coating liquid. Similarly, when cleaning, we add clean water to the coating cavity 511 or the liquid storage cavity 512 in the coating tank 50, let the booster pump circulate for a period of time to flush the waste liquid in the coating tank 50, and finally discharge the waste water through the drain pipe 508, thereby achieving the purpose of cleaning. There is no need to take out the coating tank 50 for cleaning. The action is simple, convenient and quick.

[0180] In this embodiment, the coating tank 50 is preferably made of Teflon material, but can also be made of other materials, which can ensure that the coating liquid can be maintained in the coating tank 50 for a long time.

[0181] The dip coating and curing production line of this embodiment also includes a housing 5, a touch screen 6 and at least one electric 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 electric control box 9 of the entire dip coating and curing production line is not fixed, and it can also be installed in other positions, and the number is not limited. The position and number of the electric control boxes 9 of the entire dip coating and curing production line can be adjusted appropriately according to needs. The above is only a preferred solution. The various electric control boxes 9 in this embodiment are all connected to each other and jointly control the entire dip coating and curing production line. Of course, each electric control box 9 can also control one or more parts separately, or one or more devices in the same part or different parts separately, or one or more can control the same part together, and so on.

[0182] The electric control box 9 is electrically connected to the touch screen 6 . The electric control box 9 controls the operation of the dip coating and curing production line, and the touch screen 6 performs data monitoring and parameter setting for the entire system.

[0183] In addition, this equipment is not limited to the products that can be coated and cured. Catheters and sheaths are just one of them. The surface coating can be coated and cured on strips or tubes with slender structures like catheters and sheaths.

[0184] The specific implementation steps are as follows:

[0185] (1) Preparation stage of coating:

[0186] Adding liquid: Manually add an appropriate amount of coating liquid to the coating cavity and liquid storage cavity of the coating tank.

[0187] Catheter loading: Install one end of the catheter's discharge cone interface on the carrier, and let the other end hang naturally, and complete the installation of the catheter in sequence.

[0188] (2) Four-part cycle operation stage

[0189] S1: Part 1: First coating and blowing of the catheter

[0190] Press the start button on the touch screen to start the equipment, and manually place the first carrier containing the catheter at the input end of the conveyor line of the first part. 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. The conveyor line stops moving and the barrier at the output end blocks the carrier. At this point, the first-stage robot moves directly above the first carrier, grabs the carrier, and moves it to a pre-set safe position directly above the coating tank in the first section. The cover drive extends the coating tank cover, allowing it to leave the tank. The robot continues to lower the carrier, allowing the entire portion of the catheter to be coated to enter the coating tank for the first coating. After coating, the first-stage robot lifts the carrier to a pre-set safe height, allowing the catheter to exit the coating tank for drying. The cover drive retracts the coating tank cover, which closes the tank to prevent evaporation of the coating liquid. Simultaneously, the first-stage robot grabs the carrier and moves it to a pre-set height directly above the first-stage blowdown tank. The catheter on the carrier is placed in the blowdown tank. Air from the air intake, through the carrier shaft, enters the catheter, blowing out any coating liquid that has entered the catheter's drainage hole. The first-stage robot grabs the carrier, lifts it, and places it at the input end of the second-stage conveyor line. The first-stage robot then repeats the above steps to coat the next catheter on the carrier.

[0191] S2: The first curing of the second part of the catheter.

[0192] When the photoelectric sensor at the input end of the second part of the conveyor line detects the carrier, the second part of the conveyor line moves to output the carrier forward until the photoelectric sensor at the output end detects the carrier, the second part of the conveyor line stops moving, and the baffle at the output end blocks the carrier (the time from leaving the coating tank of the first part after coating to the output end of the conveyor line of the second part is the first drying time). The manipulator of the second part moves to the top of the carrier, grabs the carrier, and moves it to the top of one of the light curing boxes in the second part to place the carrier on the adjustment device. The power probe on the carrier detects the power probe on the adjustment device and automatically turns on the power, controlling the carrier shaft drive device to operate at the specified speed, thereby driving the carrier shaft of the entire carrier to rotate. At the same time, the shading drive device contracts the shading plate, so that the curing light is evenly irradiated on the rotating catheter for curing. While the first carrier is curing, the second-part robot grabs the next carrier from the second-part conveyor line and places it in another light-curing box in the second part. Curing is performed according to the curing steps for the first carrier. While the second carrier is curing, the first carrier is cured. The second-part robot grabs the first carrier and places it on the input end of the third-part conveyor line. Then, it moves to the output end of the second-part conveyor line to grab the third carrier and place it on the previous light-curing box in the second part. Curing the catheter on the third carrier is also performed according to the above steps. While the catheter on the third carrier is curing, the catheter on the second carrier is cured. The second-part robot grabs the second carrier and places it on the input end of the second-part conveyor line. The second-part robot repeats the above steps in a cycle.

[0193] At any time when the second part is solidified, the first part is also operating synchronously according to the steps of S1.

[0194] S3: The third part is the second coating and blowing of the catheter.

[0195] When the output end of the conveyor line of the third part detects the first carrier, the robot of the third part moves to the top of the first carrier, grabs the carrier and moves it to the safety position set above the coating tank of the third part, and the cover drive extends the coating tank cover to make the coating tank cover leave the coating tank. The robot continues to descend with the first carrier so that the part of the catheter to be coated is all extended into the coating tank for the second coating. After coating, the robot of the third part lifts the first carrier upward to the set safety height so that the catheter leaves the coating tank for drying, and the cover drive retracts the coating tank cover, and the coating tank cover covers the coating tank to prevent the coating liquid from volatilizing. At the same time, the robot of the third part grabs the first carrier and moves it to the set blowing height just above the blowing tank of the third part, so that the catheter on the first carrier is placed in the blowing tank of the third part, and the air intake of the air head enters the catheter through the carrier shaft to blow out the coating liquid entering the discharge hole of the catheter. The robot arm of the third part grabs the first carrier, lifts it up and places it on the input end of the previous conveyor line of the fourth part. Then the robot arm of the third part repeats the above steps to coat the catheter on the next carrier (the second carrier, the third carrier, etc.).

[0196] At any moment of dipping and blowing of the third part, the first part and the second part are also operating synchronously according to the steps of S1 and S2 at the same time.

[0197] S4: The fourth part is the second curing of the catheter.

[0198] When the photoelectric sensor at the input end of the previous conveyor line of the fourth part detects the carrier, the previous conveyor line of the fourth part moves to output the carrier forward until the photoelectric sensor at the output end detects the carrier, the previous conveyor line of the fourth part stops moving, and the baffle at the output end blocks the carrier (the time from leaving the coating tank of the third part after coating to the output end of the previous conveyor line of the fourth part is the second drying time). The robot arm of the fourth part moves to the top of the first carrier, grabs the first carrier, moves to the top of a light curing box in the fourth part, and places the carrier on the adjustment device. The power probe on the first carrier detects the power probe on the adjustment device and automatically turns on the power, controls the carrier shaft drive device to operate at the specified speed, thereby driving the carrier shaft of the entire carrier to rotate. At the same time, the shading drive device drives The light shield retracts to allow the curing light to evenly illuminate the rotating catheter for curing. When the first carrier is curing, the robot of the fourth part will grab the next second carrier conveyed from the previous conveyor line of the fourth part, place it on another light curing box of the fourth part, and cure it according to the curing steps of the first carrier. When the second carrier is curing, the first carrier is cured. The robot of the fourth part grabs the first carrier and places it on the input end of another conveyor line of the fourth part. The sensor at the input and output end of the other conveyor line of the fourth part senses the first carrier and conveys it out. Until the output end sensor detects the first carrier, the other conveyor line of the fourth part stops moving, the barrier bar blocks the movement of the first carrier, and the first carrier is manually removed to remove the cured catheter. At the same time, after the robot of the fourth part places the first carrier on another conveyor line of the fourth part, it moves to the output end of the previous conveyor line of the fourth part to grab the third carrier conveyed over, and places it on the previous light curing box of the fourth part. The catheter on the third carrier is cured according to the above steps. While the catheter on the third carrier is curing, the catheter on the second carrier is cured. The robot of the fourth part grabs the second carrier and places it on the input end of another conveyor line of the fourth part. Waiting to be conveyed out, the robot of the fourth part operates according to the above steps in a cycle.

[0199] At any time when the fourth part is solidified, the first part, the second part and the third part are also operated synchronously according to the steps S1, S2 and S3 at the same time, and the four parts operate in a cycle according to the above steps.
