Description

Technical Field

[0001] This invention belongs to the technical field of overhead conveying equipment, specifically referring to an intelligent overhead conveying equipment for painting sheet metal parts. Background Technology

[0002] Intelligent overhead conveyor equipment is an automated logistics system that utilizes an overhead track system to continuously or intermittently transport materials in three-dimensional space via chains, friction wheels, or electrically driven carriers. Its core components consist of tracks, a drive unit, overhead carriers (hooks, racks, or pallets), and a control system. This equipment makes full use of the upper space of the factory building, enabling the aerial transfer of workpieces between various processes on the production line (such as spraying, drying, assembly, and testing). It is particularly suitable for surface treatment (such as electrophoresis and painting), automobile manufacturing, and home appliance assembly processes.

[0003] In the painting process, the overspray and dust in the environment will continuously accumulate on the conveyor chain, track, drive wheel, tensioning device, lifting tool and support. The dried paint residue may cause the chain to jam and the track to block. The accumulated material may fall off and onto the workpiece, causing pollution. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide an intelligent suspended conveying device for painting sheet metal parts, so as to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention is as follows: This invention proposes an intelligent overhead conveying device for painting sheet metal parts, comprising: The conveyor chain track is connected to multiple hooks; Two sealing strips are respectively installed on both sides of the conveyor chain track; The sealing strip has traction wheels at both ends, so that the sealing strip forms two parallel straight sections. The straight section of the sealing strip near the conveyor chain track is defined as the sealing section. The sealing section of the sealing strip is arranged parallel to the conveyor chain track, and the sealing sections of the two sealing strips are located on both sides of the bottom opening of the conveyor chain track, and the sealing sections of the two sealing strips fit together to seal the bottom opening of the conveyor chain track. The control unit is configured to control the rotation speed and direction of the rotating wheel to adjust the operating speed and direction of the sealing strip.

[0006] Furthermore, cleaning chambers are provided on both sides of the conveyor chain track, and the straight section of the sealing strip away from the conveyor chain track is defined as the cleaning section, and the cleaning section of the sealing strip extends into the cleaning chamber.

[0007] Furthermore, an infusion tube is provided on the side of the cleaning chamber near the input direction of the sealing strip, and multiple liquid nozzles facing the sealing strip are connected to the infusion tube, which is connected to an external liquid supply device.

[0008] Furthermore, the cleaning chamber is provided with multiple scrapers on the side near the input direction of the sealing strip, and the scrapers are in contact with the bottom surface of the sealing strip.

[0009] Furthermore, an air supply pipe is provided on the side of the cleaning chamber near the input direction of the sealing strip, and multiple gas nozzles facing the sealing strip are connected to the air supply pipe, which is connected to an external air supply device.

[0010] Furthermore, a drain pipe for drainage is connected to the bottom of the cleaning chamber.

[0011] Furthermore, a motor is provided on the inner side of each of the two sealing strips, and the output shaft of the motor is connected to the wheel at either end of the sealing strip to drive the wheel to rotate.

[0012] Furthermore, the conveyor chain track is provided with support frames on both sides corresponding to the rotating wheel, and the rotating wheel is connected to the support frame.

[0013] Furthermore, multiple suspensions are provided on both sides of the conveyor chain track, and the cleaning chamber is connected to the suspensions.

[0014] Furthermore, the bottom opening of the conveyor chain track is provided with side baffles on both sides for supporting the sealing section of the sealing strip.

[0015] Beneficial effects: 1. By setting rotating sealing strips on both sides of the bottom of the painting station section, and the sealing sections of the two sealing strips are in contact with each other, the bottom opening of the conveyor chain track in the painting station section is sealed. The moving hook can squeeze and push the sealing strips to both sides, allowing the conveyor chain track to pass through the sealing strips normally without being affected. The unsqueezed sealing strips remain in contact, which can effectively reduce the amount of paint mist entering the conveyor chain track and prevent the chain inside the conveyor chain track from jamming.

[0016] 2. By setting up a cleaning chamber, the sealing strip can be moved into the cleaning chamber as it rotates. High-pressure paint remover is sprayed from the paint remover nozzle in the cleaning chamber to clean the paint adhering to the sealing strip, thus preventing paint from accumulating and dripping, which could contaminate the workpiece.

[0021] The technical solutions in 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, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0022] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0023] Combination Figure 1 As shown, this embodiment of the invention provides an intelligent suspended conveying device for painting sheet metal parts, including a conveyor chain track 1, a hook 11, a sealing belt 2, a rotating wheel 3, and a control unit.

[0024] The conveyor chain track 1 is a closed loop track, and its conveying path passes through each processing station in the workshop, thereby enabling the workpiece to be conveyed to each processing station in the workshop.

[0025] The conveyor chain track 1 is equipped with a traction chain and multiple rollers. The conveyor chain track 1 is also equipped with a drive unit to drive the traction chain to run along the conveyor chain track 1. Multiple rollers are connected in series on the traction chain and are pulled by the traction chain to move along the path of the conveyor chain track 1. The hook 11 is connected to the roller. As the roller moves synchronously, the workpiece is hung on the hook 11 and can then be transported to each processing station.

[0026] Combination Figure 2 and Figure 3 As shown, the conveyor chain track 1 is provided with sealing strips 2 on both sides of the painting station section. Both ends of the sealing strip 2 are provided with rollers 3. The two ends of the sealing strip 2 are respectively fitted onto the rollers 3 at the corresponding positions. The installation spacing of the rollers 3 is adjusted so that the sealing strip 2 forms two parallel straight sections. The straight section of the sealing strip 2 closer to the conveyor chain track 1 is defined as the sealing section.

[0027] The sealing section of the sealing strip 2 is set parallel to the conveyor chain track 1. The length of the sealing section of the sealing strip 2 is greater than the length of the painting station. The sealing sections of the two sealing strips 2 are located on both sides of the bottom opening of the conveyor chain track 1, and the sealing sections of the two sealing strips 2 fit together so that the bottom opening of the conveyor chain track 1 at the painting station section is sealed.

[0028] Furthermore, the sealing strip 2 is made of rubber material with a certain thickness and good elasticity. When the hook 11 on the conveyor chain track 1 moves to the sealing section of the sealing strip 2, it can squeeze the sealing strip 2 to both sides and pass through the sealing section between the two sealing strips 2. When passing through, the unsqueezed sealing strip 2 is still in a close fit, which can effectively reduce the amount of oversprayed paint mist entering the conveyor chain track 1.

[0029] Combination Figure 1 and Figure 2 As shown, cleaning chambers 4 are provided on both sides of the conveyor chain track 1. The straight section of the sealing strip 2 away from the conveyor chain track 1 is defined as the cleaning section. The cleaning section of the sealing strip 2 extends into the cleaning chamber 4. The sealing strip 2 can be dragged and rotated by the rotating wheel 3. The sealing strip 2 located in the sealing section can move to the cleaning section, and the sealing strip 2 in the cleaning section can move to the sealing section.

[0030] During the painting process, paint will adhere to the sealing section of the sealing strip 2. As the sealing strip 2 rotates, it can move in a circular motion into the cleaning chamber 4 to clean the paint adhering to the sealing strip 2, thus preventing paint from accumulating and dripping and causing contamination of the workpiece.

[0031] Thus, the hook 11 on the conveyor chain track 1 can move along the path of the conveyor chain track 1. The workpiece is hung on the hook 11 and can then be conveyed to each processing station. On both sides of the painting station section, there are rotating sealing strips 2. The sealing sections of the two sealing strips 2 are located on both sides of the bottom opening of the conveyor chain track 1, and the sealing sections of the two sealing strips 2 are in contact with each other, so that the bottom opening of the conveyor chain track 1 at the painting station section is sealed. When the hook 11 on the conveyor chain track 1 moves to the sealing section of the sealing strip 2, it can squeeze the sealing strip 2 to both sides and pass through the sealing section of the two sealing strips 2. When passing through, the unsqueezed sealing strip 2 is still in contact, which can effectively reduce the amount of oversprayed paint mist entering the conveyor chain track 1.

[0032] At the same time, as the sealing strip 2 rotates in a cycle, it can move in a cycle into the cleaning chamber 4 to clean the paint adhering to the sealing strip 2, thus preventing paint from accumulating and dripping and causing contamination of the workpiece.

[0033] Combination Figure 5 and Figure 6 As shown, a liquid infusion pipe 41 is provided on the side of the cleaning chamber 4 near the input direction of the sealing strip 2, and multiple liquid nozzles 42 facing the sealing strip 2 are connected to the liquid infusion pipe 41. The liquid infusion pipe 41 is connected to an external liquid supply device through a delivery pipeline. The external liquid supply device delivers paint remover into the liquid infusion pipe 41 and provides a certain delivery pressure, so that the paint remover is sprayed out by the liquid nozzles 42 under high pressure and acts on the sealing strip 2.

[0034] Under the action of the paint remover, combined with the high-pressure impact of the liquid nozzle 42, the paint adhering to the sealing strip 2 is detached.

[0035] Furthermore, an air supply pipe 44 is provided on the side of the cleaning chamber 4 near the input direction of the sealing strip 2, and multiple gas nozzles 45 facing the sealing strip 2 are connected to the air supply pipe 44. The air supply pipe 44 is connected to an external air supply device through an air supply pipeline. The external air supply device supplies high-pressure gas into the air supply pipe 44, so that the gas nozzles 45 can blow high-pressure airflow onto the sealing strip 2 to remove the paint remover residue on the sealing strip 2 due to cleaning, and prevent the paint remover from dripping onto the workpiece and causing paint peeling.

[0036] Furthermore, the bottom of the cleaning chamber 4 is connected to a drain pipe 46 for drainage, through which the removed paint and paint remover are discharged.

[0037] In an optional embodiment, the bottom of the cleaning chamber 4 is designed in a V-shape, which allows the mixture of paint remover and paint to be better collected and discharged uniformly through the drain pipe 46.

[0038] Combination Figure 6 and Figure 7 As shown, multiple scrapers 43 are provided on the side of the cleaning chamber 4 near the input direction of the sealing strip 2. The scrapers 43 are in contact with the bottom surface of the sealing strip 2. After the paint remover is sprayed by the liquid nozzle 42, the scrapers 43 are used to scrape off the residual paint at the bottom of the sealing strip 2, thereby improving the cleaning effect.

[0039] Thus, when the sealing strip 2 enters the cleaning chamber 4, the liquid nozzle 42 on the infusion pipe 41 sprays paint remover for cleaning. Under the action of the paint remover, combined with the high-pressure impact of the liquid nozzle 42, the paint adhering to the sealing strip 2 is removed. As the sealing strip 2 moves, the scraper 43 scrapes off the residual paint at the bottom of the sealing strip 2, improving the cleaning effect. Subsequently, the air infusion pipe 44 blows high-pressure airflow onto the sealing strip 2 through the gas nozzle 45 to remove the paint remover residue on the sealing strip 2 caused by cleaning, preventing the paint remover from dripping onto the workpiece and causing paint peeling.

[0040] Combination Figure 1 As shown, a dust sensor 7 is installed above the painting station section of the conveyor chain track 1. The dust sensor 7 monitors the air dust content at the painting station section of the conveyor chain track 1 in real time. If the value is high, there is more overspray and more paint mist flying upwards. Correspondingly, there is also more paint adhering to the sealing strip 2. If the value is low, there is less overspray and less paint mist flying upwards. Correspondingly, there is also less paint adhering to the sealing strip 2.

[0041] It should be noted that the present invention also includes a control unit. The dust sensor 7 and the external liquid supply device are connected to the control unit by signal. According to the monitoring value of the dust sensor 7, the control unit regulates the external liquid supply device according to the preset control logic.

[0042] Thus, based on the air dust content, the control unit adjusts the supply volume and pressure of paint remover delivered to the delivery pipe 41 by the external liquid supply device. When the air dust content is high, the supply volume of paint remover is increased and the supply pressure is increased to thoroughly clean the paint on the sealing strip 2. When the air dust content is low, the supply volume and supply pressure of paint remover are reduced to save energy.

[0043] Based on the dust content in the air, the liquid supply volume and pressure of the external liquid supply equipment are intelligently adjusted to meet cleaning needs while saving energy.

[0044] Combination Figure 1As shown, a motor 31 is provided on the inner side of each of the two sealing strips 2. The output shaft of the motor 31 is connected to the wheel 3 at either end of the sealing strip 2 to drive the wheel 3 to rotate, thereby dragging the sealing strip 2 to run.

[0045] Furthermore, the motor 31 is connected to the control unit via signal. The control unit controls the rotation speed and direction of the motor 31, thereby controlling the rotation speed and direction of the rotating wheel 3 to adjust the operating speed and direction of the sealing belt 2.

[0046] Combination Figure 3 , Figure 4 and Figure 8 As shown, the rotation direction of the two motors 31 is controlled by the control unit, which in turn controls the rotation direction of the sealing strip 2. During the painting process, the rotation direction of the two motors 31 is controlled to be the same. At this time, the sealing sections of the two sealing strips 2 move in opposite directions. Through the relative rubbing of the sealing strips 2, the hook 11 can rotate itself while moving, so as to facilitate the uniform painting of the workpiece.

[0047] It should be noted that the hook 11 is rotatably connected to the roller inside the conveyor chain track 1, and the top of the hook 11 is a round rod structure, which allows it to rotate around its own axis under the relative rubbing of the two sealing strips 2.

[0048] It should be noted that the positions of the infusion tube 41 and the gas infusion tube 44 in the two cleaning chambers 4 are set according to the moving direction of the corresponding sealing strip 2. The infusion tube 41 is set at the end of the cleaning chamber 4 near the entrance of the sealing strip 2, while the gas infusion tube 44 is set at the end of the cleaning chamber 4 near the exit of the sealing strip 2, so that the cleaning process is as follows: first, the sealing strip 2 is sprayed with paint remover for cleaning, and then it is dried.

[0049] Combination Figure 1 As shown, the conveyor chain track 1 has support frames 32 on both sides corresponding to the rotating wheel 3. The rotating wheel 3 is rotatably connected to the support frame 32, and the motor 31 is also connected to the support frame 32 at the corresponding position.

[0050] Furthermore, multiple suspensions 5 are provided on both sides of the conveyor chain track 1, and the cleaning chamber 4 is connected to the suspensions 5, which support the cleaning chamber 4.

[0051] Combination Figure 1 and Figure 3 As shown, side baffles 6 are provided on both sides of the bottom opening of the conveyor chain track 1. The sealing section of the sealing strip 2 is between the two side baffles 6. The side baffles 6 support the sealing section of the sealing strip 2. When the hook 11 squeezes the sealing strip 2, the sealing strip 2 at the squeeze point can be compressed, so that the sealing strip 2 has enough friction to rub the hook 11 to rotate.

[0052] Furthermore, the side baffle 6 is longer than the paint spraying section, so that the side baffle 6 protects one side of the sealing section of the sealing strip 2 to prevent paint from adhering, while the other side of the sealing section of the sealing strip 2 is in contact with each other, so that paint cannot adhere.

[0053] The working principle of this invention is as follows: The hook 11 on the conveyor chain track 1 can move along the path of the conveyor chain track 1. The workpiece is hung on the hook 11 and can then be conveyed to each processing station. On both sides of the painting station section, there are rotating sealing strips 2. The sealing sections of the two sealing strips 2 are located on both sides of the bottom opening of the conveyor chain track 1, and the sealing sections of the two sealing strips 2 are in contact with each other, so that the bottom opening of the conveyor chain track 1 at the painting station section is sealed. When the hook 11 on the conveyor chain track 1 moves to the sealing section of the sealing strip 2, it can squeeze the sealing strip 2 to both sides and pass through the sealing section of the two sealing strips 2. When passing through, the unsqueezed sealing strip 2 is still in a close contact state, which can effectively reduce the amount of oversprayed paint mist entering the conveyor chain track 1.

[0054] Simultaneously, paint remover is first sprayed from the liquid nozzle 42 on the infusion pipe 41 for cleaning. Under the action of the paint remover, combined with the high-pressure impact of the liquid nozzle 42, the paint adhering to the sealing strip 2 is detached, preventing paint accumulation and dripping that could contaminate the workpiece. As the sealing strip 2 moves, the scraper 43 scrapes off the residual paint at the bottom of the sealing strip 2, improving the cleaning effect. Subsequently, the air infusion pipe 44 sprays high-pressure airflow onto the sealing strip 2 through the gas nozzle 45 to remove any residual paint remover on the sealing strip 2, preventing paint remover from dripping onto the workpiece and causing paint peeling.

[0055] In summary, by setting rotating sealing strips 2 on both sides of the painting station section, the sealing sections of the two sealing strips 2 are located on both sides of the bottom opening of the conveyor chain track 1, and the sealing sections of the two sealing strips 2 are in close contact with each other, so that the bottom opening of the conveyor chain track 1 at the painting station section is sealed. When the hook 11 on the conveyor chain track 1 moves to the sealing section of the sealing strip 2, it can squeeze the sealing strip 2 to both sides and pass through the sealing section of the two sealing strips 2. When passing through, the unsqueezed sealing strip 2 is still in a close contact state, which can effectively reduce the amount of oversprayed paint mist entering the conveyor chain track 1.

[0056] By setting up a cleaning chamber 4, as the sealing strip 2 rotates in a cycle, the sealing strip 2 can move in a cycle into the cleaning chamber 4 to clean the paint adhering to the sealing strip 2, thus preventing paint from accumulating and dripping and causing contamination of the workpiece.

[0057] By controlling the rotation direction of the two motors 31, the rotation direction of the sealing strip 2 is controlled. During the painting process, the rotation direction of the two motors 31 is controlled to be the same. At this time, the sealing sections of the two sealing strips 2 move in opposite directions. Through the relative rubbing of the sealing strips 2, the hook 11 can rotate itself while moving, so as to facilitate the uniform painting of the workpiece.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0059] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
