Technical Problem

[0002]点胶固化剂在使用的过程中需要利用涂胶抢对元件进行上胶处理,然后再利用固化灯对元件上涂抹过胶液的部位进行照射使其固化,但是传统的点胶固化机不仅体积大而且在使用时对元件的照射时间非常的短,短时间照射后就会直接将元件取下或者直接传送到下一道工序进行加工,但是短时间的照射只能使元件上的胶液得到初步的固化,初步固化的胶液无法保证元件之间的粘连的稳定性,而且没有固化的胶液也会吸附空气中的灰尘,灰尘进入到胶液内后会严重影响胶液的性能,而且传统的点胶设备的出胶头结构简单不具有对胶液进行节截流的功能,导致点胶完成后点胶处都会出现拉丝的问题

Benefits of technology

[0018]1、本发明使用时,通过控制动力膜的膨胀幅度即可控制出胶柱插入出胶管的深度,进而控制出胶管出胶的量,通过此种方式可对元件进行更加精准的涂胶,而当出胶柱在出胶管内向上移动的过程中出胶管的内部处于负压状态,此时出胶管内的胶液会被吸住,从而保证胶液不会从出胶管的出胶口流出,进而避免元件上端的零件被多余的胶液污染,同时由于出胶管的出胶口小于出胶管的内径,因此当胶液流过出胶口时会受到挤压,通过此种方式可避免胶液内出现气泡影响粘接效果,同时通过两次不同时间的固化可使胶液固化的更加彻底。

Description

Technical Field

[0001] This invention relates to the field of dispensing machine technology, specifically to a UV dispensing and curing machine and a curing method. Background Technology

[0002] The application of adhesive curing agents requires the use of a dispensing gun to apply the adhesive to the components, followed by curing with a curing lamp to cure the adhesive. However, traditional dispensing curing machines are not only bulky but also have very short curing times. After a short curing period, the components are either removed or transferred to the next processing step. This short curing time only allows for preliminary curing of the adhesive, which cannot guarantee the stability of the adhesion between components. Furthermore, uncured adhesive can attract dust from the air, which can severely affect the performance of the adhesive. In addition, the simple dispensing head structure of traditional dispensing equipment lacks the function of controlling the flow of adhesive, resulting in stringing problems at the dispensing point after application.

[0003] Chinese patent discloses a UV-curing dispensing machine (authorization announcement number CN215429956U). This patent employs a dispensing machine solution with a UV curing device, which improves the automation level and processing efficiency. However, the dispensing environment of this patent is completely exposed to air, making the adhesive susceptible to dust contamination during the dispensing process. Therefore, this invention provides a UV dispensing curing machine and a curing method to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a UV dispensing curing machine and a curing method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A UV dispensing and curing machine includes a dispensing box, inside which a lifting assembly is installed. The lifting assembly is fitted with a dispensing structure for dispensing, which also has a primary curing function. Two curing chambers for increasing the degree of curing are installed on the side wall of the dispensing box. Several transition windows for feeding are provided between the curing chambers and the dispensing box, and each transition window is rotatably connected to a feeding plate with a positioning function. Several components can be transported into the dispensing box for dispensing processing through the feeding plate.

[0007] The dispensing structure includes a movable sleeve, which is fitted over the outside of the lifting assembly. Support arms are movably connected to both the left and right ends of the movable sleeve. A curing lamp assembly and a dispensing head are installed opposite each other on the outer wall of the support arm.

[0008] The curing chamber comprises two housings, which are rotatably connected to the dispensing box via damping hinges. Each housing is equipped with an ultraviolet lamp, which can be used to re-cur the components inside the housing, thereby increasing the degree of curing of the adhesive.

[0009] As a further embodiment of the present invention, two connecting pipes are symmetrically fixedly connected to the outer wall of the movable sleeve. Both connecting pipes are equipped with solenoid valves inside, and the upper ends of the two connecting pipes are respectively fitted with a rubber bottle and a gas cylinder.

[0010] As a further embodiment of the present invention, the support arm is rotatably connected to the movable sleeve via a rotating sleeve, the dispensing head is slidably mounted on the lower end of the support arm via a movable slider, the lower end of the support arm is rotatably connected to a threaded rod, the movable slider is threadedly connected to the threaded rod, and the end of the support arm is also fixedly connected to a drive motor that can drive the threaded rod to rotate.

[0011] As a further embodiment of the present invention, a connector is fixedly connected to the outer wall of the rotating sleeve. The connector is connected to the dispensing head through a connecting hose. A docking groove is symmetrically opened inside the movable sleeve. The docking groove communicates with the connector. Two sets of docking channels are also symmetrically installed inside the movable sleeve. The two connectors are respectively connected to the docking channels, and the two ends of the two sets of docking channels are respectively connected to the docking groove.

[0012] Specifically, a first one-way valve is installed inside the docking channel connected to the gas cylinder. More specifically, two first pistons are symmetrically slidably connected inside the docking channel connected to the gas cylinder, and a mesh plate is fixedly connected to the side of the two first pistons that are close to each other. The first pistons and the mesh plate are connected by a connecting spring, and a second one-way valve is also provided on the outer wall of the docking channel connected to the gas cylinder.

[0013] As a further embodiment of the present invention, the dispensing head includes a glue storage column, the connecting hose is connected to the glue storage column, and the glue storage column is fixedly connected to the movable slider. The lower end of the glue storage column is rotatably connected to a support cylinder, the lower end of the support cylinder is fixedly connected to a steering plate, the inside of the steering plate is rotatably connected to a swing arm, the lower end of the swing arm is fixedly connected to a glue storage tube, the glue storage column is connected to the glue storage tube through a transport hose, and the lower end of the glue storage tube is fixedly connected to a dispensing tube, through which liquid glue can be laid on the surface of the component.

[0014] As a further embodiment of the present invention, a rotating motor is fixedly connected to the lower end of the movable slider, a steering gear is fixedly connected to the output shaft of the rotating motor, and a toothed ring is sleeved on the outside of the support cylinder, with the steering gear meshing with the toothed ring.

[0015] As a further embodiment of the present invention, a glue storage chamber is fixedly connected inside the glue storage column, one end of the transport hose is connected to the glue storage chamber, and the other end is connected to the glue storage tube. A glue dispensing column is slidably connected inside the glue storage tube. Specifically, a support plate is fixedly connected inside the glue storage tube, the glue dispensing column is slidably connected to the support plate, and a return spring is sleeved on the outside of the glue dispensing column. The inner diameter of the inner cavity of the glue dispensing tube is adapted to the outer diameter of the glue dispensing column, and the inner diameter of the glue outlet at the lower end of the glue dispensing tube is smaller than the inner diameter of the glue dispensing tube.

[0016] As a further embodiment of the present invention, a heat-conducting cavity is fixedly connected inside the glue storage tube, a dynamic membrane is fixedly connected inside the heat-conducting cavity, a heat-conducting capillary is fixedly connected inside the heat-conducting cavity, a temperature-sensing tube is fixedly connected to the end of the heat-conducting capillary away from the heat-conducting cavity, the temperature-sensing tube is fixed inside the glue storage column, and a heating wire is wound around the outside of the temperature-sensing tube. Several heat dissipation holes are also provided on the outer wall of the glue storage column.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In use, the depth of the dispensing column inserted into the dispensing tube can be controlled by controlling the expansion amplitude of the dynamic membrane, thereby controlling the amount of adhesive dispensed from the dispensing tube. This method allows for more precise adhesive application to components. As the dispensing column moves upward within the dispensing tube, the inside of the dispensing tube is under negative pressure. At this time, the adhesive in the dispensing tube is sucked in, ensuring that the adhesive does not flow out from the dispensing port of the dispensing tube, thus preventing the components at the top of the device from being contaminated by excess adhesive. At the same time, since the dispensing port of the dispensing tube is smaller than the inner diameter of the dispensing tube, the adhesive is squeezed when it flows through the dispensing port. This method can prevent air bubbles in the adhesive from affecting the bonding effect. In addition, curing at two different times allows the adhesive to cure more thoroughly.

[0019] 2. When using this invention, after placing the component on the upper end of the carrier plate, the conveying motor is turned on to drive the rotating column to rotate. When the rotating column rotates, it will drive the carrier plate to rotate through the connecting plate, thereby causing the carrier plate inside the housing to rotate into the dispensing box. During the rotation of the rotating column, the traction rope will be wound up, thereby generating negative pressure in the negative pressure chamber, which will cause the suction cup to adsorb the component and position it, thus ensuring the stability of the glue application.

[0020] 3. When using this invention, glue is supplied to the dispensing head through a glue bottle, and the glue is stably supplied into the dispensing tube through a gas cylinder, thereby allowing the invention to be independent of the external glue supply source. At the same time, the dispensing head is moved up and down by a reciprocating screw. The angle of the dispensing tube and the distance between it and the upper part of the component can be controlled by the cooperation of the steering plate, the reciprocating screw and the swing arm, thereby greatly reducing the size of the invention.

[0021] 4. When using this invention, the glue application operation is carried out in the dispensing box. This method can prevent dust in the air from falling into the glue on the component, thereby preventing dust from affecting the glue's performance. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1: Please refer to Figures 1-4 In this embodiment of the invention, the UV dispensing curing machine includes a dispensing box 1, with observation windows at both the front and rear ends of the dispensing box 1, and tempered glass inside the observation windows.

[0044] The dispensing box 1 is equipped with a lifting assembly 2 inside. The lifting assembly 2 is fitted with a dispensing structure 4 for dispensing. The dispensing structure 4 also has a primary curing function. Two curing chambers 3 are installed on the side wall of the dispensing box 1 to increase the degree of curing. Several transition windows 100 for feeding are provided between the curing chambers 3 and the dispensing box 1. Each transition window 100 is rotatably connected to a feeding plate 6 with a positioning function. Several components 7 can be transported into the dispensing box 1 for dispensing processing through the feeding plate 6.

[0045] Please refer to Figure 3 and Figure 5 The dispensing structure 4 includes a movable sleeve 400, which is sleeved on the outside of the lifting assembly 2. Both the left and right ends of the movable sleeve 400 are movably connected to support arms 406. On the outer wall of the support arm 406, a curing lamp assembly 407 and a dispensing head 5 are installed opposite each other. Specifically, the curing lamp assembly 407 is fixedly installed on the upper end of the support arm 406, while the dispensing head 5 is movably installed on the lower end of the support arm 406.

[0046] Please refer to Figure 3 The lifting assembly 2 includes a lifting motor 200, which is located above the dispensing box 1. The lower end of the output shaft of the lifting motor 200 is connected to a reciprocating screw 201 via a coupling. The moving sleeve 400 is threadedly connected to the reciprocating screw 201. Specifically, in order to ensure the stability of the moving sleeve 400, limit rods 203 are symmetrically provided on the outer side of the reciprocating screw 201. The limit rods 203 are fixedly connected to the dispensing box 1. The two limit rods 203 pass through the moving sleeve 400, and the moving sleeve 400 is slidably connected to the limit rods 203 via a sliding window 401. More specifically, a fixing plate 202 is fixedly connected between the two limit rods 203, and the lifting motor 200 is installed on the upper end of the fixing plate 202.

[0047] Please refer to Figure 4 The curing chamber 3 includes two housings 300. The housings 300 are rotatably connected to the dispensing box 1 via a damping hinge 301. Ultraviolet lamps 302 are installed inside each housing 300. The ultraviolet lamps 302 can re-cur the components 7 inside the housings 300, thereby increasing the curing degree of the adhesive. A heat sink 303 is also fixedly connected to the outer wall of the housing 300. The heat sink 303 can dissipate heat from the ultraviolet lamps 302, avoiding the problem that the temperature inside the curing chamber 3 will rise due to prolonged use of the ultraviolet lamps 302, which would make the adhesive difficult to cure.

[0048] Example 2: Please refer to Figures 3 to 12Based on Embodiment 1, two connecting pipes 402 are symmetrically fixedly connected to the outer wall of the movable sleeve 400. Solenoid valves 403 are provided inside the two connecting pipes 402, and glue bottles 404 and gas cylinders 405 are respectively clamped at the upper ends of the two connecting pipes 402. The glue bottle 404 contains liquid glue, and the gas cylinder 405 contains high-pressure gas. The high-pressure gas can make the glue liquid in the glue bottle 404 quickly reach the dispensing head 5.

[0049] Please see Figures 6 to 12 The support arm 406 is rotatably connected to the movable sleeve 400 via a rotating sleeve 408. The dispensing head 5 is slidably mounted on the lower end of the support arm 406 via a movable slider 500. A threaded rod 502 is rotatably connected to the lower end of the support arm 406. The movable slider 500 is threadedly connected to the threaded rod 502. A drive motor 501 that can drive the threaded rod 502 to rotate is also fixedly connected to the end of the support arm 406. Specifically, a sliding rail 503 is fixedly connected to the lower end of the support arm 406. The movable slider 500 is slidably connected to the sliding rail 503. The threaded rod 502 is installed inside the sliding rail 503. A connecting block 505 is fixedly connected to the outer wall of the movable slider 500. The connecting block 505 is threadedly connected to the threaded rod 502. A pulley 504 is fixedly connected to the output shaft of the drive motor 501 and the end of the threaded rod 502 away from the movable sleeve 400. The two pulleys 504 are connected by a belt.

[0050] A connector 409 is fixedly connected to the outer wall of the rotating sleeve 408. The connector 409 is connected to the dispensing head 5 via a connecting hose 506. Symmetrically arranged docking grooves 414 are provided inside the movable sleeve 400, communicating with the connector 409. Two sets of docking channels 415 are also symmetrically installed inside the movable sleeve 400. Two connecting pipes 402 are respectively connected to the docking channels 415, and both ends of the two sets of docking channels 415 are respectively connected to the docking grooves 414. Specifically, a first one-way valve 418 is installed inside the docking channel 415 connected to the gas cylinder 405. More specifically, two first pistons 419 are symmetrically slidably connected inside the docking channel 415 connected to the gas cylinder 405, and a mesh plate 421 is fixedly connected to the side of the two first pistons 419 that are close to each other. The first piston 419 is connected to the mesh plate 421 by a connecting spring. The outer wall of the docking channel 415 connected to the gas cylinder 405 is also provided with a second one-way valve 420. When the gas cylinder 405 releases gas, it pushes the first piston 419. When the first piston 419 moves, it will generate pressure in the docking channel 415 connected to the gas cylinder 405, thereby pushing the adhesive to flow quickly into the docking groove 414. When the gas cylinder 405 stops supplying gas, the first piston 419 will return to its original position under the action of the connecting spring. At this time, the outside air will enter the docking channel 415 through the second one-way valve 420 to keep the pressure in the docking channel 415 balanced with the outside. The movement of the first piston 419 can be repeatedly controlled by opening and closing the solenoid valve 403, thereby ensuring that the adhesive can quickly enter the docking groove 414.

[0051] Please see Figure 8 and Figure 9 The connector 409 has a sliding connection to a movable tube 410 inside, and a magnetic ring 411 is sleeved on the outside of the movable tube 410. The mating groove 414 has a fixed connection to a mating ring 412 inside, and an electromagnet 413 is fixedly connected to the end of the mating ring 412 away from the movable tube 410. By changing the magnetism of the electromagnet 413, the electromagnet 413 can be used to attract and repel the movable tube 410. More specifically, the electromagnet 413 can be used to control the insertion and ejection of the movable tube 410 into the mating ring 412.

[0052] A rotary motor 416 is symmetrically fixedly connected to the outer wall of the movable sleeve 400. A rotating head 417 is fixedly connected to the output shaft of the rotary motor 416. The outer wall of the rotating head 417 contacts the outer wall of the rotating sleeve 408. Specifically, the rotating head 417 is wrapped with a rubber sleeve, and the rotating sleeve 408 is fitted with a rubber ring. The rubber sleeve and rubber ring can increase the friction between the rotating head 417 and the rotating sleeve 408. That is, turning on the rotary motor 416 can drive the rotating sleeve 408 to rotate, and the rotation of the rotating sleeve 408 can drive the support arm 406 to rotate.

[0053] Please see Figure 7The dispensing head 5 includes a glue storage column 508, a connecting hose 506 connected to the glue storage column 508, and the glue storage column 508 is fixedly connected to the movable slider 500.

The upper end of the steering plate 512 is fixedly connected with an adjustment motor 517, and the output shaft of the adjustment motor 517 is fixedly connected with a worm 518, which meshes with the worm gear 516.

[0056] Please see Figure 11 and Figure 12 The glue storage column 508 is fixedly connected to the glue storage cavity 523. More specifically, the glue outlet of the connecting hose 506 is connected to the glue storage cavity 523. One end of the transport hose 519 is connected to the glue storage cavity 523, and the other end is connected to the glue storage tube 514. The glue storage tube 514 is slidably connected to the glue outlet column 521. Specifically, the glue storage tube 514 is fixedly connected to the support plate. The glue outlet column 521 is slidably connected to the support plate. A return spring is also sleeved on the outside of the glue outlet column 521. The inner diameter of the inner cavity of the glue outlet tube 520 is matched with the outer diameter of the glue outlet column 521. The inner diameter of the glue outlet at the lower end of the glue outlet tube 520 is smaller than the inner diameter of the glue outlet tube 520.

[0057] A heat-conducting cavity 527 is fixedly connected inside the glue storage tube 514. A dynamic membrane 522 is fixedly connected inside the heat-conducting cavity 527. A heat-conducting capillary 526 is fixedly connected inside the heat-conducting cavity 527. A temperature-sensing tube 524 is fixedly connected to the end of the heat-conducting capillary 526 away from the heat-conducting cavity 527. The temperature-sensing tube 524 is fixed inside the glue storage column 508, and a heating wire 525 is wound around the outside of the temperature-sensing tube 524. Several heat dissipation holes are also provided on the outer wall of the glue storage column 508.

[0058] Example 3: Please refer to Figure 13 and Figure 14Based on Embodiment 1, the feeding plate 6 includes a rotating column 601. The rotating column 601 is located inside the transition window 100 and is rotatably connected to the dispensing box 1. A conveying motor 602 is fixedly connected to the upper end of the rotating column 601. The conveying motor 602 is fixedly connected to the dispensing box 1. That is, turning on the conveying motor 602 will drive the rotating column 601 to rotate. A negative pressure pipe 604 is sleeved on the outside of the rotating column 601. The negative pressure pipe 604 is fixedly connected to the dispensing box 1. A bearing plate 600 is rotatably sleeved on the outside of the negative pressure pipe 604.

Specifically, the upper end of the support plate 600 has two sliding grooves, which are formed at 90 degrees. The positioning post 610 is located within the sliding grooves and is dampedly slidably connected to the sliding grooves. The component 7 can be positioned by the cooperation of the two positioning posts 610 and the connecting plate 603. For more details, please refer to [link to relevant documentation]. Figure 13 The left side of component 7 is attached to the connecting plate 603, and the front and right ends of component 7 are attached to the positioning post 610, thus completing the positioning of component 7.

[0060] Several suction cups 605 are fixedly connected to the upper end of the support plate 600. A negative pressure chamber 606 is opened inside the negative pressure pipe 604. The negative pressure chamber 606 is connected to several suction cups 605 through a negative pressure hose 609.

That is, when the rotating column 601 rotates, it can wrap around the traction rope 608, thereby pulling the second piston 607 through the traction rope 608, thus generating negative pressure inside the negative pressure chamber 606.

[0061] The working principle of this invention is:

[0062] When loading, open the housing 300, place the component 7 on the upper end of the support plate 600, close the housing 300 after loading, turn on the conveying motor 602 to rotate the support plate 600 into the dispensing box 1, and at the same time, the suction cup 605 will attract the component 7 and thus position the component 7.

[0063] After placing component 7 on the upper end of the carrier plate 600, turning on the conveying motor 602 will drive the rotating column 601 to rotate. When the rotating column 601 rotates, it will drive the carrier plate 600 to rotate through the connecting plate 603, thereby causing the carrier plate 600 inside the housing 300 to rotate into the dispensing box 1. During the rotation, the rotating column 601 will retract the traction rope 608, thereby generating negative pressure in the negative pressure chamber 606, which will cause the suction cup 605 to adsorb and position the component 7, thus ensuring the stability of the glue application.

[0064] Before dispensing, the solenoid valve 403 is opened to allow the liquid adhesive to flow into the docking groove 414 through the docking channel 415. Then, the solenoid valve 403 corresponding to the gas cylinder 405 is controlled to intermittently open and close repeatedly, thereby increasing the flow rate of the adhesive bag using the first piston 419. The adhesive then enters the storage tube 514 through the docking groove 414, the connecting hose 506, and the transport hose 519. It is worth noting that because the storage column 508 has a storage chamber 523, the adhesive will accumulate in the storage chamber 523, thereby reducing air bubbles in the adhesive.

[0065] Then, the adjusting motor 517 is turned on to drive the swing arm 515 to rotate, adjusting the angle of the dispensing tube 520 so that the edge of the component 7 can be coated with glue, thus making the glue application more accurate and even. When the dispensing tube 520 is adjusted to the appropriate angle, the heating wire 525 is turned on to heat the temperature sensing tube 524, thereby increasing the temperature in the heat conduction cavity 527, causing the power diaphragm 522 to expand and push the dispensing column 521. Then, the glue is pushed out of the dispensing tube 520 by the dispensing column 521 to apply glue to the component 7. When the glue in the dispensing tube 520 is squeezed out, the heating wire 525 is turned off. At this time, the temperature of the temperature sensing tube 524 will drop. In order to ensure that the temperature in the glue storage column 508 drops quickly, a cooling fan (not shown in the figure) is fixedly connected to the lower end of the steering plate 512. Then the power diaphragm 522 will reset, and the dispensing column 521 will also reset under the action of the reset spring.

[0066] After the adhesive is applied, adjust the polarity of the electromagnet 413 to separate the movable tube 410 from the mating ring 412. Then, turn on the rotary motor 416 to rotate the support arm 406 180 degrees. Then, use the curing lamp group 407 to briefly cure the adhesive-coated component 7 for 2-3 seconds. Then, turn on the conveying motor 602 again to carry the adhesive-coated component 7 into the housing 300 for secondary curing, so that the adhesive is cured more thoroughly. When it is necessary to apply adhesive again, control the support arm 406 to reset so that the movable tube 410 is mated with the mating ring 412 again. By curing for two different times, the adhesive can be cured more thoroughly.

[0067] The depth of the dispensing column 521 inserted into the dispensing tube 520 can be controlled by controlling the expansion amplitude of the dynamic membrane 522, thereby controlling the amount of glue dispensed from the dispensing tube 520. This method allows for more precise glue application to the component 7. As the dispensing column 521 moves upward within the dispensing tube 520, the inside of the dispensing tube 520 is under negative pressure. At this time, the glue in the dispensing tube 520 is sucked in, thus ensuring that the glue does not flow out from the dispensing port of the dispensing tube 520. This prevents the components at the top of the component 7 from being contaminated by excess glue (if excess glue in the dispensing tube 520 is not restricted, it will flow out naturally and easily contaminate the components). At the same time, since the dispensing port of the dispensing tube 520 is smaller than the inner diameter of the dispensing tube 520, the glue will be squeezed when it flows through the dispensing port. This method can prevent air bubbles in the glue from affecting the bonding effect.

[0068] This invention supplies adhesive to the dispensing head 5 via a glue bottle 404 and ensures a stable flow of adhesive into the dispensing tube 520 via a gas cylinder 405, thereby eliminating the need for an external adhesive supply source. Simultaneously, the reciprocating screw 201 controls the up-and-down movement of the dispensing head 5. The angle of the dispensing tube 520 and the distance between it and the upper part of the component 7 can be controlled through the cooperation of the steering plate 512, the reciprocating screw 201, and the swing arm 515, thus greatly reducing the usable size of this invention.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
