Description

Technical Field

[0001] This utility model relates to the field of air conditioning filter processing technology, and more specifically, to an adhesive coating device for processing automotive air conditioning filters. Background Technology

[0002] The automotive air conditioning filter processing adhesive application device is an automated equipment specifically designed for sealing the longitudinal seams of filter elements. Its core function is to ensure the integrity and sealing performance of the filter element structure by precisely controlling the adhesive application. It typically consists of a feeding system, an adhesive application system, a curing system, and a control system. It can adapt to the processing of filter elements made of different materials such as polypropylene and glass fiber, and meet the stringent requirements of the automotive industry for filter elements' oil resistance, temperature resistance, and environmental performance.

[0003] Traditional automotive air conditioning filter coating equipment often relies on direct air pressure extrusion or simple metering pumps for coating. Air pressure extrusion is significantly affected by ambient temperature, adhesive viscosity fluctuations, and system pressure stability, making it difficult to maintain a stable output adhesive volume. Simple metering pumps, due to their structural limitations, have poor linearity control at low output volumes and are insufficiently adaptable to changes in process parameters. Neither of these methods can achieve precise and continuous linear adjustment of the adhesive output per unit time, resulting in large fluctuations in coating quality during production. The adhesive strips are sometimes thick and sometimes thin, and there may even be localized adhesive breaks or irregular adhesive accumulation. This not only significantly increases the product defect rate and affects the reliability of the final product, but also causes significant waste of raw materials due to repeated adhesive replenishment and waste disposal.

[0004] In summary, to improve product quality, it is necessary to address the problem that traditional automotive air conditioning filter processing adhesive coating devices struggle to maintain a stable adhesive output, leading to significant fluctuations in adhesive coating quality during production and affecting the reliability of the final product. The goal is to enable the adhesive coating device to perform adhesive coating work uniformly and precisely. Utility Model Content

[0005] The present invention provides an adhesive coating device for automotive air conditioning filter processing, which aims to solve the problem that the output amount of adhesive from traditional automotive air conditioning filter processing adhesive coating devices is difficult to maintain, resulting in large fluctuations in adhesive coating quality during the production process and affecting the reliability of the final product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating device for automotive air conditioning filter processing, comprising a conveyor belt, a gantry frame fixedly connected to the conveyor belt, two symmetrical first guide rods fixedly connected to both sides of the gantry frame, a first electric push rod fixedly connected to the gantry frame, a slide fixedly connected to the output end of the first electric push rod, the first electric push rod being used to drive the slide to move along the first guide rod, a rotating assembly mounted on the slide, a transmission assembly connected to the output end of the rotating assembly, a slider connected to the power output end of the transmission assembly, the slider and the slide being slidably connected, the rotating assembly driving the slider to move along the slide through the transmission assembly, a coating housing fixedly connected to the slider, the coating housing having, from top to bottom, a pushing chamber, a rotating chamber, a vacuum chamber, an extrusion chamber and a coating port, a coating assembly mounted in the rotating chamber, a sliding bearing connected to the output end of the coating assembly, the coating assembly being used to drive the sliding bearing to rotate, a connecting rod fixedly connected inside the sliding bearing, a helical rod fixedly connected to the bottom of the connecting rod, the helical rod being rotatably connected in the extrusion chamber.

[0007] In a preferred embodiment, the rotating assembly includes a first motor fixedly connected to the carriage, a first synchronous pulley fixedly connected to the output end of the first motor via a shaft, and a belt with one end sleeved on the first synchronous pulley. The first motor is used to drive the first synchronous pulley to rotate.

[0008] In a preferred embodiment, the transmission assembly includes a second synchronous pulley sleeved on the other end of the belt, a threaded rod fixedly connected to the second synchronous pulley, and two second guide rods symmetrically distributed on both sides of the threaded rod. The threaded rod is rotatably connected to the carriage, the second guide rods are fixedly connected to the carriage, the threaded rod is threadedly connected to the slider, and the second guide rods are slidably connected to the slider.

[0009] In a preferred embodiment, the adhesive application assembly includes a second motor fixedly connected to the rotating cavity, a first gear fixedly connected to the output end of the second motor via a shaft, and a second gear meshing with one side of the first gear. The second gear is movably connected via a limit key and a sliding bearing, and the second motor is used to drive the first gear to rotate.

[0010] In a preferred embodiment, a glue storage shell is fixedly connected to the slider, and a conveying pipe is fixedly connected between the glue storage shell and the extrusion chamber.

[0011] In a preferred embodiment, a piston is provided between the sliding bearing and the screw rod, the piston and the connecting rod are rotatably connected, and the piston is slidably connected in the vacuum chamber.

[0012] In a preferred embodiment, a second electric push rod is fixedly connected inside the push cavity. The output end of the second electric push rod is fixedly connected to the connecting rod, and the second electric push rod is used to drive the connecting rod to move along a preset direction.

[0013] In a preferred embodiment, a third electric push rod is fixedly connected to the slider, and a mounting frame is fixedly connected to the output end of the third electric push rod. The third electric push rod is used to drive the mounting frame to move in the vertical direction. A scraper is fixedly connected to the bottom of the mounting frame, and an auxiliary roller is rotatably connected to the bottom of the mounting frame.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model uses a second motor to drive the screw rod to rotate precisely in the extrusion chamber via a gear set, transforming the control of glue output into precise control of the motor speed. This achieves high-precision, programmable linear control of the glue extrusion volume, ensuring the uniformity and consistency of the glue strip, fundamentally reducing glue waste and improving the sealing quality of the filter element.

[0015] 2. This utility model sets up a piston driven by a second electric push rod in the vacuum chamber. When the glue coating is finished, the piston retracts slightly and quickly, forming an instantaneous negative pressure in the extrusion chamber, effectively sucking back the glue liquid, and cleanly and neatly breaking the glue thread. This completely solves the problem of glue dripping, keeps the working environment clean, and realizes the full automation of the production process.

[0016] 3. This utility model has a scraper and an auxiliary roller controlled by a third electric push rod set behind the glue applicator. After the glue is applied, the mechanism immediately presses down, the auxiliary roller compacts the glue strip, and the scraper removes excess glue. This strengthens the adhesion between the glue strip and the filter element substrate, eliminates interfacial air, and improves the bonding strength and sealing reliability.

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Refer to the instruction manual appendix Figures 1 to 6 A coating device for processing automotive air conditioning filters includes a conveyor belt 1, a gantry frame 2 fixedly connected to the conveyor belt 1, two symmetrical first guide rods 3 fixedly connected to both sides of the gantry frame 2, a first electric push rod 4 fixedly connected to the gantry frame 2, a slide 5 fixedly connected to the output end of the first electric push rod 4, the first electric push rod 4 driving the slide 5 to move along the first guide rods 3, a rotating assembly mounted on the slide 5, a transmission assembly connected to the output end of the rotating assembly, a slider 8 connected to the power output end of the transmission assembly, the slider 8 and the slide 5 being slidably connected, and the rotating assembly... The slider 8 is driven to move along the slide frame 5 by the transmission component. A glue coating housing 9 is fixedly connected to the slider 8. The glue coating housing 9 is provided with a pushing chamber 901, a rotating chamber 902, a vacuum chamber 903, an extrusion chamber 904 and a glue coating port 905 from top to bottom. A glue coating component is installed in the rotating chamber 902. A sliding bearing 13 is connected to the output end of the glue coating component. The glue coating component is used to drive the sliding bearing 13 to rotate. A connecting rod 14 is fixedly connected in the sliding bearing 13. A screw rod 16 is fixedly connected to the bottom of the connecting rod 14. The screw rod 16 is rotatably connected in the extrusion chamber 904.

[0026] It should be noted that the conveyor belt 1 is responsible for carrying the filter element workpiece and realizing intermittent feeding in a horizontal direction. The first electric push rod 4 drives the slide 5 to move in the vertical direction. The slide 5 has smooth through holes on both sides. The size of the through holes is adapted to the first guide rod 3 to ensure the stability and accuracy of the slide 5 during movement and prevent the slide 5 from deviating or jamming during movement. It also drives the slider 8 to move on the slide 5 through the rotating component and the transmission component, so that the glue applicator head can reach any specified position in three-dimensional space to execute complex planar or spatial glue applicator trajectories. The model of the first electric push rod 4 in this device is JC35-500-24-50.

[0027] It is worth noting that the pushing cavity 901 is located at the top, which provides a certain amount of room for movement and power for the subsequent connecting rod 14. The rotating cavity 902 is equipped with a glue coating assembly. The glue coating assembly outputs power to drive the sliding bearing 13, connecting rod 14 and screw rod 16 to rotate. When the screw rod 16 rotates, it will mesh and push the rubber material downward. Furthermore, by precisely controlling the rotation speed of the screw rod 16, the precise measurement and control of the rubber material extrusion amount can be achieved.

[0028] Refer to the instruction manual appendix Figure 3 The rotating assembly includes a first motor 601 fixedly connected to the slide 5, a first synchronous pulley 602 fixedly connected to the output end of the first motor 601 via a shaft, and a belt 603 with one end sleeved on the first synchronous pulley 602. The first motor 601 is used to drive the first synchronous pulley 602 to rotate.

[0029] It should be noted that the first motor 601 is mounted on the slide 5, and drives the belt 603 to rotate through the first synchronous pulley 602. Then, the belt 603 is used to transmit power to the transmission component. There is a sufficiently large friction between the first synchronous pulley 602 and the belt 603 to achieve stable power transmission. The model of the first motor 601 in this device is 42CM02.

[0030] Refer to the instruction manual appendix Figure 3 and Figure 4 The transmission assembly includes a second synchronous pulley 701 sleeved on the other end of the belt 603, a threaded rod 702 fixedly connected to the second synchronous pulley 701, and two second guide rods 703 symmetrically distributed on both sides of the threaded rod 702. The threaded rod 702 is rotatably connected to the slide 5, the second guide rod 703 is fixedly connected to the slide 5, the threaded rod 702 is threadedly connected to the slider 8, and the second guide rod 703 is slidably connected to the slider 8.

[0031] It should be noted that the belt 603 drives the second synchronous pulley 701 to rotate, which in turn drives the threaded rod 702 to rotate. When the threaded rod 702 rotates, the slider 8 is restricted in its rotational freedom by the second guide rods 703 on both sides. According to the principle of "screw transmission", the rotational motion of the threaded rod 702 is forced into the precise linear motion of the slider 8 along the axial direction of the threaded rod 702. The slider 8 has a threaded hole and two through holes. The size of the threaded hole is adapted to the size of the threaded rod 702 to achieve stable power transmission. The size of the through holes is adapted to the size of the second guide rod 703.

[0032] Refer to the instruction manual appendix Figure 6 The adhesive application assembly includes a second motor 1201 fixedly connected in the rotating cavity 902, a first gear 1202 fixedly connected to the output end of the second motor 1201 via a shaft, and a second gear 1203 meshing with one side of the first gear 1202. The second gear 1203 is movably connected to a limit key and a sliding bearing 13. The second motor 1201 is used to drive the first gear 1202 to rotate.

[0033] It should be noted that the second motor 1201 is installed in the rotating cavity 902 and rotates the sliding bearing 13 through the first gear 1202 and the second gear 1203, thereby driving the connecting rod 14 to rotate. The first gear 1202 and the second gear 1203 are dimensionally matched to achieve stable power transmission. The model of the second motor 1201 in this device is ECMA-E.

[0034] It is worth noting that the outer ring of the sliding bearing 13 is slidably connected to the second gear 1203, and the inner ring of the sliding bearing 13 is rotatably connected to the connecting rod 14. When the second gear 1203 rotates, it will drive the sliding bearing 13 to rotate. When the connecting rod 14 moves linearly, there is a relative displacement between the sliding bearing 13 and the second gear 1203. The sliding bearing 13 moves with the connecting rod 14, while the position of the second gear 1203 remains constant and always meshes with the first gear 1202, thereby realizing multiple motion states of the connecting rod 14.

[0035] Refer to the instruction manual appendix Figure 4 A glue storage shell 10 is fixedly connected to the slider 8, and a conveying pipe 11 is fixedly connected between the glue storage shell 10 and the extrusion chamber 904.

[0036] It should be noted that the glue storage shell 10 and the glue application shell 9 are both mounted on the slider 8 and are a synchronously moving whole. At the same time, the glue storage shell 10, the conveying pipe 11, the extrusion chamber 904 and the glue application port 905 are connected in sequence to achieve a stable supply of glue. In addition, the glue storage shell 10 is equipped with a visible liquid level window, which makes it convenient for operators to intuitively observe the remaining glue and replenish it in time.

[0037] Refer to the instruction manual appendix Figure 5 A piston 15 is provided between the sliding bearing 13 and the screw rod 16. The piston 15 and the connecting rod 14 are rotatably connected. The piston 15 is slidably connected in the vacuum chamber 903. The sliding bearing 13 and the connecting rod 14 are driven by the power element, which drives the piston 15 to rise rapidly and slightly upward, instantly forming a local and slight negative pressure in the extrusion chamber 904 below.

[0038] It should be noted that piston 15 is used to isolate the extrusion chamber 904 from other chambers above, preventing the glue from damaging the workpiece in the upper chamber. When a section of glue application is completed, the screw rod 16 stops rotating. This negative pressure generates an upward suction force, which just counteracts the gravity and flow inertia of the glue, and can "pull back" a little bit of the glue hanging at the glue nozzle 905, thereby effectively breaking the glue thread and preventing residual glue from dripping. When it is necessary to change to a different type of glue, or when the extrusion chamber 904 needs to be cleaned due to glue curing, the piston 15 is driven to move upward significantly, all the way back to the upper part of the vacuum chamber 903, creating a large and continuous operating space at the rear of the extrusion chamber 904, which facilitates better cleaning.

[0039] Refer to the instruction manual appendix Figure 5 A second electric push rod 17 is fixedly connected inside the push cavity 901. The output end of the second electric push rod 17 is fixedly connected to the connecting rod 14. The second electric push rod 17 is used to drive the connecting rod 14 to move along a preset direction.

[0040] It should be noted that the second electric push rod 17 is used as a power element to drive the connecting rod 14 to move up and down in the glued housing 9, thereby driving the piston 15 to move. The model of the second electric push rod 17 in this device is JC35-500-24-50.

[0041] Refer to the instruction manual appendix Figure 4 A third electric push rod 18 is fixedly connected to the slider 8. A mounting bracket 19 is fixedly connected to the output end of the third electric push rod 18. The third electric push rod 18 is used to drive the mounting bracket 19 to move in the vertical direction. A scraper 20 is fixedly connected to the bottom of the mounting bracket 19. An auxiliary roller 21 is rotatably connected to the bottom of the mounting bracket 19.

[0042] It should be noted that the scraper 20 and the auxiliary roller 21 are located behind the glue application port 905. After the glue application port 905 is completed, the third electric push rod 18 immediately extends and drives the mounting frame 19 to descend, so that the scraper 20 and the auxiliary roller 21 at the bottom contact the freshly applied and uncured glue strip with a preset pressure, pressing the raised glue strip downward to make it fully contact the surface of the filter element substrate, eliminating any air that may be trapped between the glue strip and the substrate, and enhancing the bonding strength and sealing performance. The model of the third electric push rod 18 in this device is JC35-500-24-50.

[0043] Working principle: Conveyor belt 1 carries the filter element workpiece to the gluing station. Then, the first electric push rod 4 drives the slide 5 to move along the first guide rod 3. At the same time, the first motor 601 starts, driving the second synchronous wheel 701 and the threaded rod 702 to rotate through the first synchronous pulley 602 and belt 603. This forces the slider 8, which is threaded to the threaded rod 702 and constrained by the second guide rod 703, to move along the slide 5, so that the gluing housing 9 is located at the designated gluing starting point. Subsequently, the adhesive material enters the extrusion chamber 904 of the gluing housing 9 from the adhesive storage housing 10 through the conveying pipe 11. The second motor 1201 in the rotating chamber 902 drives the first gear 1202 and the second gear 1203 to mesh and drive the sliding bearing 13 and the connecting rod 14 to rotate. Finally, the screw rod 16 rotates in the extrusion chamber 904, causing the adhesive to be extruded from the coating nozzle 905. While the adhesive is being applied at the coating nozzle 905, the third electric push rod 18 drives the mounting frame 19 to descend, causing the scraper 20 and auxiliary roller 21 at the bottom of the mounting frame 19 to scrape off excess adhesive, roll and compact the uncured adhesive strip, and enhance its adhesion to the substrate. After the adhesive is applied, the second electric push rod 17 can drive the connecting rod 14 and piston 15 to move upward in the vacuum chamber 903, causing the piston 15 to rise slightly and generate negative pressure in the extrusion chamber 904, effectively preventing the adhesive from dripping when the adhesive is applied. When changing the adhesive or cleaning, the piston 15 is driven to move upward significantly, all the way to the upper part of the vacuum chamber 903, so that the residual adhesive can flow out of the extrusion chamber 904.

[0044] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
