Description

Technical Field

[0001] The present application relates to the technical field of manufacturing fake fishing baits, and in particular to an automated spraying production line and production method for lure baits. Background Art

[0002] When fishing with lures, lures are used to lure fish to the bait. The shape of the lures is similar to that of small fish, shrimp or insects. In the production process of lures, plastic, metal or silicone are used as raw materials. After the lures are shaped, they need to be painted.

[0003] At present, manual spraying is mainly used. The operator holds a spray gun to spray paint on the lure hanging on the assembly line. After spraying the front, the back is sprayed. This method has technical problems such as high labor intensity, high labor cost and low efficiency. Although there are robots for automated spraying on the market, for example, the patent application number is 202311745636.4, a robot system for fine spraying of lures. Although this invention can replace manual spraying, the spraying operation of this system requires workers to place the fixture tooling on the workbench, and cannot realize automated transfer operation. This is because it is difficult to locate the position of the fixture during the automated flow process. Once there is a problem with the positioning of the fixture, it will directly affect the spraying accuracy of the lure on the fixture.

[0081] Hereinafter, the present application will be further described based on preferred embodiments with reference to the accompanying drawings.

[0082] In addition, various components on the drawings are enlarged (thickened) or reduced (thinned) for ease of understanding, but this practice is not intended to limit the scope of protection of the present application.

In addition, in the description of the present application, in order to distinguish different units, the words first, second, etc. are used in this specification, but these are not limited by the order of manufacture, nor can they be understood as indicating or implying relative importance, and their names may be different in the detailed description and claims of the present application.

[0085] The vocabulary in this specification is used to illustrate the embodiments of the present application, but is not intended to limit the present application. It should also be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or a connection between the two elements. For those skilled in the art, the specific meanings of the above terms in this application can be specifically understood.

[0086] For the convenience of description, taking the X, Y, and Z directions shown in the figure as an example, an automatic spraying production line for lures includes a fixture 1, a spraying device 2, a lifting device 3, a reversing conveying mechanism 4, a drying device 5, and a conveying track S1. A conveyor belt for conveying along the X direction is arranged on the conveying track S1, so that the fixture 1 is transferred along the X direction on the conveying surface of the conveying track S1. The spraying device 2 is arranged on the side of the conveying track S1 along the Y direction, and the lifting device 3 corresponding to the spraying device 2 is arranged below the conveying surface of the conveying track S1. The lifting device 3 is used to stop the conveying of the fixture 1 on the conveying track S1 and locate the position of the fixture 1 after stopping. The spraying device 2 is used to transfer the positioned fixture 1 to its interior and spray the fake bait 9 clamped on the fixture 1. The drying device 5 is arranged at the conveying end of the conveying track S1 and is used to paint the fake bait 9 on the fixture 1 that has completed the spraying operation.

[0087] The fixture 1 is conveyed along the X direction on the conveying track S1 by the conveying device. After being conveyed to the top of the lifting device 3, it is positioned by the lifting device 3 and lifted upward along the Z direction. At this time, the translation mechanism of the spraying device 2 located on the side is displaced along the Y direction to the bottom of the base of the fixture 1. When the translation mechanism of the spraying device 2 is displaced along the Y direction to cooperate with the lifting platform 35, the lifting platform 35 falls back along the Z direction, so that the fixture 1 on the lifting platform 35 is transferred to the spraying device 2 for spraying operation. After the spraying operation is completed, the fixture 1 is transferred to the lifting device 3 along the Y direction by the translation mechanism of the spraying device 2. At this time, the lifting device 3 drops the fixture 1 downward along the Z direction and cancels the positioning. The conveying device on the conveying track S1 conveys the fixture 1 along the X direction again. The fixture 1 needs to complete three-dimensional displacement in the X, Y and Z directions on the lifting device 3.

[0088] Specifically, the lifting device 3 includes a fixed base 31, a non-return assembly 32, a blocking mechanism 34, and a lifting platform 35. The blocking mechanism 34 and the lifting platform 35 are connected to the bottom of the conveying track S1 through the fixed base 31, and are displaced up and down along the Z direction on the conveying surface of the conveying track S1. The blocking mechanism 34 is arranged at a positioning initial end of the conveying track S1. The non-return assembly 32 is connected to the inner side of the conveying track S1 and is arranged at a positioning end on the conveying track S1. The fixture 1 is unidirectionally transported along the conveying track S1 above the non-return assembly 32. When the blocking mechanism 34 is displaced along the Z direction to the top of the conveying track S1, the fixture 1 is stopped by the rising blocking mechanism 34 and is positioned between the non-return assembly 32 and the blocking mechanism 34.

[0089] The lifting platform 35 is disposed between the non-return assembly 32 and the blocking mechanism 34 , and moves upward along the Z direction to lift the positioned fixture 1 . The lifting platform 35 lifts the fixture 1 to detach from the conveying track S1 , and positions it at the lifting terminal of the lifting platform 35 .

[0090] In some preferred embodiments, the number of the spraying devices 2 can be multiple, and accordingly, the multiple spraying devices 2 are arranged on the side of the conveying track S1 along the Y direction, and the lifting device 3 corresponding to the spraying device 2 is arranged below the conveying surface of the conveying track S1, and the non-return assembly 32 and the blocking mechanism 34 are respectively arranged on both sides of the lifting device 3, which means that spraying can be carried out at multiple workstations on the spraying production line, and every two adjacent non-return assemblies 32 and the blocking mechanism 34 are a positioning point.

[0091] In some preferred embodiments, in order to ensure that the fixture 1 can be accurately positioned at a designated position on the lifting device 3 after each displacement during the above-mentioned workstation transfer process, the applicant optimizes the structure of the fixture 1 and the lifting device 3 as follows.

[0092] In some preferred embodiments, recessed portions 112 are respectively provided on both sides of the clamp 1 , and the recessed portions 112 are used to cooperate with the blocking mechanism 34 of the lifting device 3 for positioning.

[0093] In some preferred embodiments, the lifting device 3 also includes a sensor 36, which is arranged at the positioning end on the conveying track S1 and is used to identify the conveying position of the clamp 1. When the sensor 36 identifies that the clamp 1 is conveyed to the positioning end, the sensor 36 sends a delay signal to the control system, and the control system controls the blocking mechanism 34 to move upward along the Z direction after a delay to block the conveyance of the clamp 1 along the X direction.

[0094] In some preferred embodiments, a sensor is also provided on the blocking mechanism 34 for identifying the position of the clamp 1, so as to feedback the position signal to the control system and prevent interference between two adjacent clamps 1 during the transmission and transfer process on the transmission track S1.

[0095] Specifically, the fixed base 31 is connected to the bottom of the conveying track S1, and the blocking mechanism 34 is connected to the top of the fixed base 31. The top of the blocking mechanism 34 is displaced in the Z direction above and below the conveying surface of the conveying track S1, so that when the clamp 1 is conveyed above the conveying surface of the conveying track S1, when positioning is not required, the lowest displacement point of the top of the blocking mechanism 34 does not touch the substrate 11 of the clamp 1, and when positioning is required, the highest displacement point of the top of the blocking mechanism 34 can pass through the recessed portion 112 of the substrate 11 and be stuck in the recessed portion 112.

[0096] In some preferred embodiments, the blocking mechanism 34 includes a blocking part 341 and a driving part 342. The blocking part 341 is connected to the output end of the driving part 342. Under the action of the driving part 342, the blocking part 341 moves up and down along the Z direction. When it is necessary to position the fixture 1 transmitted on the transmission track S1, the driving part 342 drives the blocking part 341 to be lifted until it is locked in the recessed part 112, so as to block the transmission of the fixture 1 along the X direction.

[0097] In some preferred embodiments, the driving part 342 may be a cylinder, or may be a lead screw and a ball bearing, or an electric cylinder, etc., and the specific structure is not further limited herein.

[0098] In some preferred embodiments, if the clamp 1 suddenly collides with the blocking part 341 during transportation, under the reaction force of the blocking part 341, the clamp 1 will be displaced in the opposite direction of the conveying direction. In order to reduce this displacement deviation, the applicant has optimized the structure of the blocking part 341. The blocking part 341 includes a bottom plate 3411, an elastic member 3412, and a stopper 3413. The bottom plate 3411 is connected to the output end of the driving part 342. The stopper 3413 is a triangular structural member. The middle corner of the stopper 3413 is hinged to the bottom plate 3411. One end of the stopper 3413 is connected to the bottom plate 3411 through the elastic member 3412, and the other end is suspended. When the clamp 1 touches the suspended end of the stopper 3413, the clamp 1 will push the stopper 3413 to press against the elastic member 3412 with its hinge point as the fulcrum to achieve the deceleration movement of the clamp 1.

[0099] In some preferred embodiments, a roller is connected to one end of the stopper 3413 in a suspended state, so that when the stopper 3413 and the clamp 1 move relative to each other, the friction resistance during the displacement process can be reduced to minimize the displacement of the clamp 1 due to the friction resistance.

[0100] In some preferred embodiments, although the elastic blocking mechanism 34 can reduce the displacement of the clamp 1 in the opposite direction of the conveying direction, there is still a certain positioning deviation. In order to further reduce the position deviation of the clamp 1 due to the displacement in the opposite direction, the lifting device 3 also includes a check assembly 32. The check assembly 32 is connected to the inner side of the conveying track S1 and is located behind the conveying of the blocking mechanism 34. When the clamp 1 is conveyed into place on the conveying track S1, the check assembly 32 is stuck on the side of the clamp 1.

[0101] In some preferred embodiments, the non-return assembly 32 is composed of a shell and a spring, one end of the spring is hinged to the shell, and the other end is elastically connected to the shell through a spring. When the spring protrudes from the shell, along the X-direction transmission direction, the surface of the shell and the highest point of the top of the spring are smoothly transitioned. Along the opposite direction of the X-direction transmission, the highest point of the top of the spring is set as a vertical plane relative to the surface of the shell, ensuring that the clamp 1 can only be transmitted in one direction along the X-direction. When the transmission is in place, the spring will immediately pop out and be stuck on the side of the substrate 11. The non-return assembly 32 is a prior art, and the specific structure is not further limited here.

[0102] In some preferred embodiments, the lifting device 3 also includes a lifting drive mechanism 33, the lifting platform 35 is arranged between the non-return assembly 32 and the blocking mechanism 34, the mounting seat of the lifting drive mechanism 33 is fixedly connected to the fixed base 31, and the output end of the lifting drive mechanism 33 is connected to the lifting platform 35 along the Z direction. Under the driving action of the lifting drive mechanism 33, the lifting platform 35 moves up and down along the Z direction to lift the clamp 1 off the conveying track S1.

[0103] In some preferred embodiments, in order to achieve precise positioning of the lifting platform 35 and the clamp 1, a positioning protrusion 351 is provided on the table top of the lifting platform 35, and correspondingly, a positioning hole 113 is provided on the back side of the substrate 11. When the clamp 1 is positioned by the non-return assembly 32 and the blocking mechanism 34, the positioning protrusion 351 corresponds to the positioning hole 113.

[0104] In some preferred embodiments, two positioning holes 113 are provided, and the two positioning holes 113 are respectively provided on both sides of the first opening 111 to enhance the stability of positioning.

[0105] In some preferred embodiments, one of the positioning holes 113 is a waist-shaped hole, which is used to prevent the substrate 11 from deforming due to thermal expansion and contraction in different seasons, thereby preventing the positioning accuracy from being affected.

[0106] When the clamp 1 is stopped and positioned by the lifting platform 35 , the translation mechanism of the spraying device 2 starts to work, transfers the clamp 1 into the spraying device 2 , and completes the spraying operation on the lure 9 in the spraying device 2 .

[0107] Specifically, the spraying device 2 includes a supporting enclosure mechanism 21, a spraying operation box 26, an actuator 22, a paint supply mechanism 23, and a feeding mechanism 25. The supporting enclosure mechanism 21 is used to fix and install other mechanisms, the paint supply mechanism 23 is used to provide paint, and the actuator 22 is used to spray the paint provided by the paint supply mechanism 23 onto the lure 9. The actuator 22 is arranged on one side of the spraying operation box 26 and is connected to the output end of the paint supply mechanism 23. The nozzle 223 of the actuator 22 passes through the side wall of the spraying operation box 26 and has the displacement freedom of the spraying operation in the spraying operation box 26.

[0108] The spraying operation box 26 is connected with a transfer rail 253 arranged along the Y direction, and the other end of the transfer rail 253 extends along the Y direction to be located above the conveying track S1. The feeding mechanism 25 is slidably connected to the top of the transfer rail 253 along the Y direction, and is located on the same horizontal plane as the lifting platform 35 located at the lifting terminal, or is located below the lifting platform 35 at the lifting terminal;

[0109] The feeding mechanism 25 is moved back and forth between the spraying operation box 26 and the bottom of the lifting platform 35 via the transfer guide rail 253 to transfer the fixture 1 into the spraying operation box 26 or return the fixture 1 after spraying to the lifting platform 35 .

[0110] In some preferred embodiments, the feeding mechanism 25 includes a feeding drive mechanism 251 and a feeding portion 252, the output end of the feeding drive mechanism 251 is connected to the feeding portion 252, one end of the feeding portion 252 is connected to the box body 261, and the other end can extend out of the spraying operation box 26. The feeding portion 252 can reciprocate in the horizontal direction under the driving action of the feeding drive mechanism 251, so as to horizontally transfer the lure 9 clamped by the clamp 1 to the spraying operation box 26 or move it out of the spraying operation box 26.

[0111] In some preferred embodiments of the present application, a sensor is also provided on the transfer guide rail 253. The length of the transfer guide rail 253 along its horizontal direction is adjustable. The sensor can monitor the size of the clamp 1, thereby realizing the adjustment of the length of the limit clamp 1 of the transfer guide rail 253, thereby ensuring the adaptation of the feeding mechanism 25 to clamps 1 of different sizes.

[0112] In some specific embodiments of the present application, the feeding portion 252 is a plate-like structure with a middle portion penetrating along the Z direction, and the feeding portion 252 is open on the side facing the lifting platform 35, so as to avoid the lifting platform 35 and allow waste liquid and waste gas generated by the spraying operation to fall downward through the middle portion.

[0113] In some preferred embodiments of the present application, a positioning structure that matches the bottom of the clamp 1 is also provided on the feeding portion 252 to achieve accurate positioning between the feeding portion 252 and the clamp 1 .

[0114] In some specific embodiments of the present application, a positioning pin is provided on the upper part of the feeding part 252, and a positioning through hole cooperating with the positioning pin is provided on the bottom of the fixture 1, so as to achieve accurate positioning of the fixture 1 and the feeding part 252. It is conceivable that the feeding part 252 and the fixture 1 can also be accurately positioned by providing a positioning through hole on the feeding part 252 and providing a positioning pin cooperating with the positioning through hole on the bottom of the fixture 1. Regardless of the method used, as long as the relative position of the feeding part 252 and the fixture 1 can be fixed and the stability of the spraying operation can be ensured, it can be used.

[0115] When the feeding part 252 transfers the fixture 1 into the spraying operation box 26 , the actuator 22 sprays the lure 9 clamped on the fixture 1 .

[0116] The specific structure of the actuator 22 will be introduced in detail below. The actuator 22 includes an operating device 221, a connecting rod 222 and a nozzle 223. The operating device 221 is connected to the nozzle 223 through the connecting rod 222. At least one nozzle 223 is provided, and at least one nozzle 223 is connected to the paint supply mechanism 23 through a pipeline. The operating device 221 can control the movement of the nozzle 223 in different directions through the connecting rod 222 to achieve efficient spraying operations.

[0117] In some preferred embodiments of the present application, in order to improve work efficiency, the number of nozzles 223 is set to be multiple. In order to achieve the connection between the nozzle 223 and the connecting rod 222, the actuator 22 also includes a mounting plate 224, which is connected to the end of the connecting rod 222 away from the operating device 221, and is equipped with multiple nozzles 223. In actual application scenarios, the number of nozzles 223 and the number of paint containers 231 can be set based on the needs of the operation, and different colors of paint can be contained in different paint containers 231 to achieve the spraying of different colors of paint.

[0118] It is conceivable that the operating device 221 can be a cylinder, a motor, etc. In some preferred embodiments of the present application, the operating device 221 is a spraying robot, which can complete a high-efficiency and high-precision spraying operation.

[0119] After the spraying operation is completed, if the paint in the nozzle 223 pipeline is not cleaned up, the paint will solidify, thereby affecting the next operation. For this reason, the applicant has improved the paint supply mechanism 23.

[0120] In some preferred embodiments of the present application, the paint supply mechanism 23 includes a paint container 231 and a paint cleaning agent container 232, and the number of the paint container 231 is at least one, and the discharge port of at least one paint container 231 and the paint cleaning agent container 232 is connected to the nozzle 223 of the actuator 22 through a pipeline.

[0121] In some preferred embodiments of the present application, the paint supply mechanism 23 further includes a switching valve and a switching valve driving mechanism. The switching valve is arranged at the junction of the discharge port pipeline of the paint container 231 and the discharge port pipeline of the paint cleaning agent container 232. The switching of the discharge port pipelines of different containers can be realized under the switching of the switching valve driving mechanism. The paint cleaning agent in the paint cleaning agent container 232 can fill the pipeline of the actuator 22, thereby completing the cleaning of the paint in the pipeline, thereby realizing the self-cleaning function of the pipeline, avoiding the solidification and clogging of the paint in the pipeline, saving the labor cost and time cost of later cleaning, and extending the service life of the spray device 2.

[0122] In some preferred embodiments of the present application, the paint supply mechanism 23 also includes a stirring structure, which is installed in the paint container 231 and / or the paint cleaning agent container 232, and is used to stir the liquid in the container to prevent the liquid from settling and solidifying while ensuring uniform mixing of the liquid, thereby ensuring the spraying effect.

[0123] Furthermore, the nozzle 223 needs to be cleaned in time after the spraying operation is completed. If it is not cleaned in time, the paint remaining inside the nozzle 223 will solidify and cause the nozzle to be clogged. Fig.12 and Fig.15 As shown, the spraying operation box 26 also includes at least one cleaning agent holding box 265, which is used to hold paint cleaning agent and is installed in the box body 261. The operation device 221 can drive the nozzle 223 to extend into the cleaning agent holding box 265 through the connecting rod 222 to achieve cleaning of the nozzle 223.

[0124] It is conceivable that the paint cleaning agent in the cleaning agent holding box 265 can be filled by manual addition or by assembling a paint cleaning agent barrel on the spraying device 2.

[0125] In some preferred embodiments of the present application, in order to ensure that the actuator 22 completes the environmental protection purpose during the spraying operation, the spraying operation box 26 in the present application is a box that can form a relatively closed state, which is used to provide an operating space for the spraying operation of the actuator 22. The nozzle 223 of the actuator 22 sprays the paint onto the lure 9 in the spraying operation box 26. On the one hand, it can effectively reduce the emission of paint mist and odor, and prevent the leakage of paint particles, which not only reduces the pollution to the environment, but also protects the health of the operator; on the other hand, the spraying operation box 26 provides a stable spraying environment, and the closed environment reduces the influence of external factors on the spraying process, ensures that the paint is uniform and the quality is stable, and improves the coating quality and efficiency.

[0126] Furthermore, in order to ensure that the spraying operation box 26 remains in a relatively closed state when the nozzle 223 moves in different directions, the spraying operation box 26 includes a box body 261 and a curtain body 262. A through hole corresponding to the curtain body 262 is opened on the side of the box body 261. The connecting rod 222 and the nozzle 223 pass through the curtain body 262 from the through hole to enter the box body 261. The bottom edge is in an open state. The spraying operation box 26 is connected to the processing mechanism 24 through the opening of the bottom edge to realize the treatment of waste liquid and waste gas generated by spraying.

[0127] Specifically, the curtain body 262 is connected to a side of the box body 261 facing the operating device 221 and is a non-integrated structure. It extends in the vertical direction and includes a plurality of independent curtain body units.

[0128] In some preferred embodiments of the present application, the curtain body 262 is made of a transparent or translucent soft material, such as PVC, PET, etc. On the one hand, the connecting rod 222 and the nozzle 223 can be conveniently and unobstructedly moved in the horizontal and vertical directions and in and out of the box body 261; on the other hand, Fig.13 As shown, during the spraying operation, the connecting rod 222 is always in a state of passing through the curtain body 262, and the above-mentioned material can be attached to the side of the connecting rod 222, so that the curtain body 262 is in a relatively seamless state, further ensuring the realization of a relatively closed state of the spraying operation box 26.

[0129] In some preferred embodiments of the present application, the two ends of the curtain body 262 along its horizontal extension direction are connected to the side walls of the box body 261 through a movable locking device. The movable locking device can drive the curtain body 262 to move in the vertical direction, thereby adjusting the height of the curtain body 262 to achieve switching between a relatively closed state and an open state, thereby meeting different operating requirements.

[0130] Furthermore, in order to ensure that the lure 9 does not interfere with the box 261 when it is transferred into the box 261, a square through hole is provided at the bottom of the opposite side of the curtain body 262 in the box 261 to allow the lure 9 to pass horizontally. The through hole can also be set to other shapes, as long as it allows the lure 9 to pass.

[0131] Furthermore, the spray head 223 generally completes the spraying operation through the principle of compressed air. Since the negative pressure at the front end of the nozzle of the spray head 223 is often strong, the spray head 223 is very likely to produce splashing when spraying the paint onto the lure 9. In order to further ensure the relatively closed state of the spraying operation box 26, as shown in FIG. Figure 3 ,like Fig.13 , Fig.14 and Fig.15 As shown, the spray operation box 26 also includes a second overflow baffle 263 and a third overflow baffle 264. The second overflow baffle 263 is located on the side of the box body 261 corresponding to the curtain body 262, and is connected to the through hole on the side of the box body 261 corresponding to the curtain body 262. The third overflow baffle 264 is connected between the feeding parts 252, and its position corresponds to the position of the through hole that allows the lure 9 to pass through horizontal displacement. Since the curtain body 262 is a non-integrated structure, the curtain body 262 has a problem of loose sealing when intercepting splashing paint. The second overflow baffle 263 is located below the connecting rod 222 and the nozzle 223, and can intercept the splashing paint on one side of the curtain body 262; the third overflow baffle 264 is used to intercept the splashing paint of the square through hole through which the lure 9 is horizontally displaced. Through the arrangement of the second overflow baffle 263 and the third overflow baffle 264, the splashing paint is further intercepted from splashing out of the box body 261, so that the relatively closed state of the box body 261 is more stable and reliable.

[0132] Furthermore, in order to prevent the feeding portion 252 from interfering with the third overflow baffle 264 during the displacement of the lure 9 , the third overflow baffle 264 is rotatably connected to the box body 261 .

[0133] It is conceivable that the third overflow baffle 264 can be rotatably connected to the box body 261 by means of hinges, gears, pins, etc. No matter which connection method is used, as long as the third overflow baffle 264 can be switched between the horizontal direction and the vertical direction.

[0134] In some preferred embodiments, the spraying device 2 further includes a processing mechanism 24, which is used to process the excess material formed by the spraying of the actuator 22 to achieve environmental protection of the working environment. The present application uses the processing mechanism 24 to simultaneously process the waste such as droplets formed by the spraying during the spraying operation, thereby reducing the time cost and labor cost of separate processing after spraying, and reducing the safety and environmental problems caused by the waste.

[0135] The specific structure of the processing mechanism 24 will be introduced in detail below. The processing mechanism 24 is located below the actuator 22, and includes a waste gas processing structure 241 and a waste liquid processing structure 242. The waste gas processing structure 241 is used to collect and discharge the waste gas generated during the spraying operation, and the waste liquid processing structure 242 is used to process and collect dripping paint. The waste liquid cannot be discharged directly, so it needs to be collected after processing.

[0136] The waste liquid treatment structure 242 includes a connected liquid flushing component 2421 and a recovery box 2422. The liquid flushing component 2421 is located below the actuator 22 after the spraying operation is completed. It is used to flush away the dripping paint and form waste liquid mixed with paint to prevent the dripping paint from adhering to the surface of the device, thereby reducing the labor cost and time cost of subsequent processing. The recovery box 2422 is used to collect the waste liquid mixed with paint to prevent the waste liquid from spreading and causing environmental problems.

[0137] Specifically, the liquid flushing component 2421 includes a liquid supply portion 24211, a first overflow baffle 24212, a slope portion 24213, a liquid receiving box 24214 and a first vacant portion 24215. The slope portion 24213 is connected to the upper interior of the liquid receiving box 24214. The liquid supply portion 24211 and the first overflow baffle 24212 are connected to the upper portion of the slope portion 24213. The liquid supply portion 24211 is used to provide liquid for flushing the paint. The first overflow baffle 24212 is used to ensure that the liquid provided by the liquid supply portion 24211 can overflow only after reaching a certain amount. The slope portion 24213 is used to cooperate with the first overflow baffle 24212 to store liquid while guiding the overflowed liquid along its slope through the first vacant portion 24215 into the liquid receiving box 24214.

[0138] Furthermore, the slope portion 24213 includes a liquid containing plate 242131 and an overflow slope 242132 which are connected in sequence along the slope direction thereof. The liquid containing plate 242131 is connected between the first overflow baffle 24212 and the liquid receiving box 24214 in the horizontal direction. The liquid containing plate 242131, the first overflow baffle 24212 and the liquid receiving box 24214 surround and form a semi-enclosed structure with an opening at the top. The liquid provided by the liquid supply portion 24211 flows into the semi-enclosed structure. The top surface height of the first overflow baffle 24212 is lower than the top surface height of the liquid receiving box 24214 in the semi-enclosed structure. When the liquid level in the semi-enclosed structure reaches the top surface of the first overflow baffle 24212, the liquid will overflow from the top surface of the first overflow baffle 24212 to the overflow slope 242132. On the one hand, the top surface height of the first overflow baffle 24212 is higher than the overflow slope 242132, which increases the liquid flow rate and reduces the probability of the paint adhering to the overflow slope 242132; on the other hand, compared with not setting the first overflow baffle 24212, the liquid flushing component 2421 after setting the first overflow baffle 24212 can ensure that the liquid flows out continuously after filling the semi-closed structure, so that the overflow slope 242132 is always covered with liquid, so that the paint dripping from the actuator 22 flows into the liquid receiving box 24214 in a timely and continuous manner from the semi-closed structure through the overflow slope 242132 and the first vacant portion 24215, ensuring that the paint does not adhere to the overflow slope 242132.

[0139] In some preferred embodiments of the present application, the overflow slope 242132 includes multiple slope structures, which are connected end to end, and the corresponding elevation angles of the multiple slope structures increase successively in the direction approaching the bottom of the slope. Compared with the slope of a single slope structure, since the slope structure of the multiple slope structures close to the bottom of the slope has a large elevation angle, when the waste liquid mixed with the coating liquid flows through the adjacent slope structures, it not only prevents the waste liquid from rebounding, but also further reduces the probability of the coating in the waste liquid adhering to the overflow slope 242132.

[0140] Furthermore, the slope portion 24213 also includes a leakage plate 242133 connected to one end of the overflow slope 242132 along the extension direction of its slope, and the length of the leakage plate 242133 along the width direction of its slope is smaller than the slope width of the overflow slope 242132, so that at least one first gap 24215 is formed between the leakage plate 422133 and the liquid receiving box 24214 along at least one side of the slope width direction, and the waste liquid flowing down the overflow slope 242132 flows into the liquid receiving box 24214 through the first gap 24215, and then flows into the recovery box 2422 from the liquid receiving box 24214.

[0141] Furthermore, in order to ensure that the waste liquid can flow from the liquid receiving box 24214 into the recovery box 2422 , the bottom surface of the liquid receiving box 24214 is a slope structure, and the slope is arranged toward the recovery box 2422 .

[0142] Furthermore, the recovery box 2422 is a box-type structure with an opening at the top.

[0143] Furthermore, the waste liquid with the coating continuously flows into the recycling tank 2422. To improve the waste liquid treatment efficiency, the present application treats the waste liquid in the recycling tank 2422. Figure 5 As shown, the recovery box 2422 includes a transition box 24221, a filtrate box 24222 and a filter part 24223. The transition box 24221 is connected to the liquid receiving box 24214, and is infiltration-connected to the filtrate box 24222 through the filter part 24223. When the waste liquid in the transition box 24221 flows to the filtrate box 24222, under the osmotic action of the filter part 24223, the filter part 24223 only allows small molecules such as water to pass through, and large molecules such as paint cannot penetrate through the filter part 24223, so that the paint remains in the transition box 24221, and the permeate in the filtrate box 24222 does not contain paint.

[0144] In some preferred embodiments of the present application, as the spraying operation proceeds, the permeate in the filtrate box 24222 will continue to increase. On the one hand, the permeate can be discharged by setting an external pipeline on the filtrate box 24222. On the other hand, the volume of the filtrate box 24222 can be increased to accommodate enough permeate. The above two methods have the problems of high cost, large space occupation, and waste of water resources. Therefore, if Figure 5 As shown, the waste liquid treatment structure 242 in the present application further includes a liquid pipeline 2423, one end of the liquid pipeline 2423 is connected to the filtrate box 24222, and the other end is connected to the liquid supply part 24211. The present application can recycle the permeate through the liquid pipeline 2423, while saving cost and space, it also achieves the environmental protection goal.

[0145] In some specific embodiments of the present application, due to the setting of the liquid pipeline 2423, the liquid in the liquid supply part 24211 does not need to be taken from an external pipeline. Therefore, the liquid supply part 24211 in the present application is a tubular structure with multiple through holes at the bottom. The liquid can flow from the bottom through holes into the semi-closed structure formed by the liquid holding plate 242131, the first overflow baffle 24212 and the liquid receiving box 24214.

[0146] In some preferred embodiments of the present application, in order to ensure the stable connection of the slope portion 24213, the liquid flushing component 2421 further includes a surrounding connection portion 24216 and a limiting portion 24217. The surrounding connection portion 24216 is connected to the outer side of the liquid receiving plate 242131 and the two ends of the slope width of the overflow slope 242132. The slope portion 24213 is connected to the liquid receiving box 24214 through the surrounding connection portion 24216. The limiting portion 24217 is connected to one end of the liquid leakage plate 242133 along the slope extension direction of the slope portion 24213 and extends in the vertical direction. The outer side of the limiting portion 24217 abuts against the inner side of the liquid receiving box 24214 and cooperates with the end of the liquid leakage plate 242133 to abut against the end face of the liquid receiving box 24214. Through the above arrangement, it is ensured that the slope portion 24213 can be stably connected to the liquid receiving box 24214.

[0147] Furthermore, in order to ensure the abutment and cooperation between the overflow slope 242132, the limiting portion 24217 and the liquid receiving box 24214, a second vacant portion is opened on the side of the liquid receiving box 24214, and the second vacant portion is opened on the side of the liquid receiving box 24214 corresponding to the bottom of the overflow slope 242132, the bottom end of the side abuts against the top end of the overflow slope 242132, and the upper inner side of the side abuts against the outer side of the limiting portion 24217.

[0148] In some specific embodiments of the present application, the exhaust gas treatment structure 241 includes a cover body 2411 and an exhaust duct 2412 connected to the cover body 2411. The cover body 2411 and the exhaust duct 2412 are connected to the side of the liquid receiving box 24214 in sequence. The cover body 2411 is set on the slope facing the slope portion 24213. The exhaust duct 2412 is connected to an external exhaust device. The external exhaust device takes away the exhaust gas generated in the spraying operation and discharges and collects it through the airflow generated by the internal fan.

[0149] Furthermore, part of the flowing liquid on the overflow slope 242132 flows directly into the liquid receiving box 24214 from the first gap 24215, and part of it flows along the bottom surface of the cover body 2411 in the direction of the exhaust pipe 2412. Therefore, in some specific embodiments of the present application, the bottom surface of the cover body 2411 is a slope structure, and its slope is arranged toward the slope portion 24213.

[0150] In some preferred embodiments of the present application, in order to prevent the liquid from entering the exhaust pipe 2412 when there is too much liquid in the cover body 2411, the exhaust gas treatment structure 241 also includes a liquid baffle 2413, which is vertically connected to one end of the cover body 2411 close to the exhaust pipe 2412, and can prevent the liquid from flowing back into the exhaust pipe 2412.

[0151] In some preferred embodiments, the spraying device 2 also includes a driving device 20, which is arranged on the side of the box 261. The output end of the driving device 20 is reset in the box 261 along the Y direction and flexibly engaged with the clamp (1), so as to be connected to the clamp 1 and drive a plurality of lures 9 on the clamp 1 to rotate synchronously.

[0152] In some preferred embodiments, the clamp 1 includes a base plate 11 and a transmission assembly 12 and a clamping assembly 13 arranged on the base plate 11, the clamping assembly 13 includes several groups of clamping kits arranged along the X-axis direction, any group of clamping kits includes two clamping units 133 arranged opposite to each other along the Y-axis direction, the two clamping units 133 are respectively used to clamp the head and tail ends of the fake bait 9, and there is an elastic clamping space between the two clamping units 133 of the same group of clamping kits, the transmission assembly 12 includes a first synchronous transmission group 122 located on the head end side of the fake bait 9, a second synchronous transmission group 123 located on the tail end side of the fake bait 9, and a first transmission shaft 121 connecting the first synchronous transmission group 122 and the second synchronous transmission group 123, the end of one end of the first transmission shaft 121 is provided with a clutch 125 for connecting to a driving device, and the other end is simultaneously connected to and transmitted with the two synchronous transmission groups 122 to drive each group of clamping kits to rotate synchronously.

[0153] Furthermore, the output end of the driving device 20 is provided with a column shaft 2011 engaged with the clutch connection hole 1251. Under the action of the translation driving member, the driving device 20 is displaced toward or away from the clutch 125 to achieve the engagement or separation of the column shaft 2011 and the clutch connection hole 1251.

[0154] When the driving device 20 is connected to the clutch 125, the driving device 20 drives the transmission assembly 12 to rotate through the clutch 125, and then drives the fishhook clamping assembly 13 to rotate, so that the bionic bait body on the fishhook clamping assembly 13 can rotate. At this time, the bionic bait body is fully sprayed through the external spraying equipment to ensure the spraying effect of the bionic bait body.

[0155] In some preferred embodiments, the column shaft 2011 is arranged at the rotation axis of the output end of the driving device 20, and the column shaft 2011 is a prism. Accordingly, the clutch connection hole 1251 is arranged at the center of the clutch 125, and the hole shape matches the outer shape of the column shaft 2011, so as to drive the clutch 125 to rotate by inserting the column shaft 2011 into the clutch connection hole 1251, thereby driving the transmission assembly 12 to rotate.

[0156] However, in actual applications, due to batch processing, the drive device 20 and the clutch 125 will frequently engage or disengage. After each separation, it is difficult to ensure that the position angles of the prismatic column shaft 2011 and the clutch connection hole 1251 are consistent. This also leads to difficulties in engaging the two due to position angle deviation during the engagement process. For this reason, the applicant further optimized the above scheme.

[0157] In some preferred embodiments, Figure 3 As shown, the column shaft 2011 is an eccentrically arranged cylindrical shaft, and the eccentricity means that the axis of the column shaft 2011 is not coaxial with the rotation axis of the driving device 20. The number of the column shafts 2011 is at least two, and at least two of the eccentric column shafts 2011 are connected to one side of the table 2012, and are centrally symmetrically distributed with respect to the center of the table 2012. The center of the other side of the table 2012 is connected to the center of the rotation axis of the driving device 20, so that when the rotation axis of the driving device 20 rotates, the table 2012 can drive at least two of the column shafts 2011 to rotate in a circle with respect to the center of the rotation axis.

[0158] Correspondingly, the clutch connection holes 1251 are arranged in a plurality, and the plurality of clutch connection holes 1251 are circumferentially distributed along the center of the clutch 125, and the column shaft 2011 is arranged at a position corresponding to any clutch connection hole 1251, so as to realize rapid engagement of the column shaft 2011 with the clutch connection hole 1251 and stably drive the clutch 125 to rotate.

[0159] In some preferred embodiments, the end of the column shaft 2011 is in the shape of a bullet head for quick engagement, so that even if there is a deviation in the engagement position of the column shaft 2011 with the clutch connection hole 1251, it can still engage with the clutch connection hole 1251 at different positions or angles to meet different production needs.

[0160] In some preferred embodiments, in order to avoid rigid collision of the column shaft 2011 during the engagement process due to engagement position deviation, the applicant optimizes the structure of the drive device 20.

Under the action of the transmission assembly 12, several groups of the clamping kits rotate synchronously to rotate the clamped lures 9 to the same spraying angle.

The auxiliary drive shaft 1241 and the first transmission shaft 121 are respectively provided with a first auxiliary drive wheel 1242 and a second auxiliary drive wheel 1243.

[0169] In some preferred embodiments, the clamp 1 further includes a positioning baffle 16, which is coaxially arranged with the driven wheel 1224 and is used to determine the rotation angle of the clamped lure 9. Correspondingly, a rotation positioning sensor is also arranged in the spraying device 2, and the positioning baffle 16 is arranged toward the rotation positioning sensor and rotates within the sensing surface of the rotation positioning sensor to detect the rotation angle of the lure 9, so as to adjust the spraying position.

[0170] In some preferred embodiments, the production line also includes a reversing conveying mechanism 4, and the number of the conveying tracks S1 and the reversing conveying mechanism 4 is two. The two conveying tracks S1 are arranged in parallel, and the ends of the two conveying tracks S1 are respectively connected by the reversing conveying mechanism 4, so that the production line is arranged in a ring shape to save production space.

[0171] In some preferred embodiments, the reversing transmission mechanism 4 includes a first reversing mechanism 42 and a second reversing mechanism 43, wherein the first reversing mechanism 42 is slidably connected to the second reversing mechanism 43 along the Y direction; a clamp 421 displaced along the X direction is provided in the first reversing mechanism 42, and the clamp 421 is used to clamp the fixture 1 in and out of the first reversing mechanism 42 along the X direction.

[0172] After the clamp 1 completes the spraying operation in the spraying device, the clamp 1 is transferred to the first conveying track, and is conveyed to the above-mentioned reversing conveying mechanism along the positive direction of the X direction on the first conveying track. The reversing conveying mechanism conveys the clamp 1 along the Y direction, and then conveys it to the second conveying track along the reverse direction of the X direction, and continues to be transferred along the reverse direction of the X direction on the second conveying track to the drying device to complete the painting work, thereby automatically completing the spraying and painting operations of the clamp 1. By adopting the above-mentioned reversing conveying mechanism, the automated production line can be arranged in a U shape. This arrangement scheme can save the site occupied by the automatic device, and in order to ensure that the clamp 1 after the transfer position can be accurately positioned during the transmission process, the applicant optimizes the structure of the reversing conveying mechanism.

[0173] Specifically, for ease of description, Fig.26 For example, the X, Y, and Z directions in Fig.26 As shown, the reversing conveying mechanism includes a first reversing mechanism 42 and a second reversing mechanism 43. The first reversing mechanism 42 is provided with a clamp 421 that slides along the X direction, and the first reversing mechanism 42 is slidably connected to the second reversing mechanism 43 along the Y direction, so as to realize the conveying of materials along the X direction and the Y direction respectively.

[0174] In some preferred embodiments, Fig. 27 As shown, the first reversing mechanism 42 includes an inner frame 420, a clamp 421, and a base 422. The clamp 421 is connected to the top of the inner frame 420 along the X direction, and the output end of the clamp 421 is arranged downward along the Z direction. The base 422 is connected to the inside of the inner frame 420 and is located below the clamp 421. The clamp 421 and the base 422 cooperate to realize the forward and reverse direction movement of the fixture 1 along the X direction.

[0175] In some preferred embodiments, Fig.28 As shown, the clamp 421 includes a first driving part 4211, a second driving part 4212, a first mounting plate 4213, and a clamping part 4214. The output end of the first driving part 4211 is connected to the first mounting plate 4213, one side of the first mounting plate 4213 is connected to the second driving part 4212, and the output end of the second driving part 4212 is connected to the clamping part 4214. Under the action of the first driving part 4211, the clamping part 4214 is reset along the X direction, and under the action of the second driving part 4212, the clamping part 4214 is reset along the Z direction.

[0176] In some preferred embodiments, the clamping portion 4214 is a folded plate with the outer side bent downward. When transfer is required, under the action of the second driving portion 4212, the folded edge of the clamping portion 4214 extends downward and is inserted into the frame edge of the first opening 111 of the clamp 1. Then, under the action of the first driving portion 4211, the clamping portion 4214 pulls the clamp 1 to move along the X-axis to the inside of the first reversing mechanism 42.

[0177] In some preferred embodiments, the clamping jaw 421 further includes a first sensor 4215 , which is connected to the outer side of the clamping portion 4214 and is used to identify whether the clamp 1 is transmitted to the outer side of the clamping portion 4214 .

[0178] In some preferred embodiments, the base 422 includes a base frame 4221 and a roller 4223. Fig.29 As shown, the rollers 4223 are arranged in a plurality, and the rollers 4223 are arranged along the X direction and connected to the upper portion of the base frame 4221 along the Y direction, so as to reduce the friction resistance of the clamp 1 when displacing above the base frame 422 .

[0179] In some preferred embodiments, in order to further reduce the friction resistance of the clamp 1 on the base 422, the roller 4223 located at the end can also be set as a driving wheel driven by a motor, so that when the clamp 1 moves to the base 422, the roller 4223 can drive the clamp 1 to move.

[0180] In some preferred embodiments, the base support 422 also includes a guide plate 4222, and the number of the guide plates 4222 is two. The two guide plates 4222 are respectively arranged at the two ends of the roller 4223 and connected to the top of the base support frame 4221. The setting distance of the two guide plates 4222 along the Y direction is adapted to the width of the clamp 1, so that when the clamp 1 is displaced above the roller 4223, it can only move within the area defined by the two guide plates 4222.

[0181] In some preferred embodiments, in order to enable the clamp 1 to smoothly enter the limited area of ​​the two guide plates 4222, the inner edges and corners of the ends of the two guide plates 4222 are chamfered so that the end entrances and exits of the two guide plates 4222 cooperate with each other to form a wide-mouth shape.

[0182] In some preferred embodiments, the base support 422 also includes a second sensor 4224 and a third sensor 4225. The second sensor 4224 and the third sensor 4225 are connected to the guide plate 4222 and are respectively arranged corresponding to the head and tail ends of the clamp 1 that has been displaced into place, and are used to detect whether the clamp 1 is completely displaced to the specified position on the base support 422.

[0183] In some preferred embodiments, when the clamp 1 in the reversing mechanism is displaced into place, the output end of the clamp 421 retracts, and at this time, the second reversing mechanism 43 drives the first reversing mechanism 42 to displace along the Y direction.

[0184] In some preferred embodiments, the second reversing mechanism 43 includes an outer frame 431 and a second reversing drive mechanism 432. The first reversing mechanism 42 is connected to the output end of the second reversing drive mechanism 432, and the second reversing drive mechanism 432 is connected to the lower part of the outer frame 431 along the Y direction. Under the driving action of the second reversing drive mechanism 432, the first reversing mechanism 42 is displaced in the positive and negative directions along the Y direction inside the second reversing mechanism 43.

[0185] When the first reversing mechanism 42 moves to the end along the Y direction in the second reversing mechanism 43, the output end of the clamp 421 extends downward along the Z direction and is inserted into the gap between the inner frame of the first opening 111 and the lure. At this time, the clamp 421 cooperates with the base 422 to move in the opposite direction of the X direction, so as to drive the clamp 1 to move to the second conveying track for the next process.

[0186] The present application also provides a method for producing lure baits by automated spraying, which uses the above-mentioned lure bait automated spraying production line for processing, and comprises the following steps:

[0189] Step 3: The lifting platform 35 moves upward along the Z direction until the lifting fixture 1 is separated from the conveying track S1 to the specified position. At this time, the blocking mechanism 34 falls back to the bottom of the conveying track S1;

[0190] Step 4: The feeding mechanism 25 moves to the bottom of the fixture 1 along the Y direction through the transfer guide rail 253, and positions the fixture 1 to the designated position of the feeding mechanism 25. At this time, the lifting platform falls back to the bottom of the conveying track S1;

[0191] Step 5: The feeding mechanism 25 moves in the reverse direction along the Y direction through the transfer guide rail 253 to transfer the fixture 1 to the spraying operation box 26;

[0192] Step 6: The driving device 20 drives the transmission assembly 12 of the fixture 1 to rotate. When the plurality of lures 9 held on the fixture 1 rotate synchronously to a specified position, the actuator 22 sprays the lures 9 held on the fixture 1 in the spraying operation box 26.

[0193] Step 7: The feeding mechanism 25 sends the sprayed fixture 1 back to the conveying track S1 along the X direction through the transfer guide rail 253 along the Y direction;

[0194] Step 8: After the lifting platform 35 moves upward along the Z direction to the lifting fixture 1, the feeding mechanism 25 returns to the spraying device 2 along the Y direction. At this time, the lifting platform 35 moves downward along the Z direction to place the fixture 1 on the conveying track S1;

[0195] Step 9: The conveying track S1 conveys the fixture 1 along the X direction to the next station of the spraying device 2 or the reversing conveying mechanism 4 or the drying device 5.
