Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and more specifically, to a multi-axis precision transfer adhesive coating device. Background Technology

[0002] Multi-axis precision transfer coating equipment is an automated device used for high-precision coating processes. It is commonly used in fields such as semiconductor packaging, electronic component assembly, or precision optical device manufacturing. Its core function is to precisely transfer the adhesive from the storage system to the surface of the target substrate through the coordinated control of multiple motion axes, such as X / Y / Z axes and rotation axes.

[0003] Current adhesive application equipment uses a precision metering system, such as a screw pump or pneumatic dispensing valve, to drip adhesive at a set flow rate onto a localized area of ​​the transfer wheel during the application process. The transfer wheel then rotates, while the squeegee system maintains stable contact pressure with the wheel surface. Through their combined action, the adhesive is gradually spread and dispersed across the entire working surface of the transfer wheel. Finally, when the transfer wheel reaches the workpiece contact point, the adhesive is transferred to the workpiece surface under the combined action of pressure and adhesion, completing the application process. However, in practical use, dripping adhesive onto the transfer wheel to ensure sufficient coverage causes the squeegee to rotate around the wheel while applying the adhesive. During this process, the rheological properties of the adhesive cause it to tend to accumulate at the leading edge of the squeegee, making it difficult to spread evenly to both sides of the transfer wheel. This effect results in a significantly thicker adhesive layer in the central area of ​​the transfer wheel than on the sides, leading to an uneven adhesive layer on the workpiece—thicker in the center and thinner at the edges. Therefore, improvements and optimizations are needed. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a multi-axis precision transfer coating device, which has the advantage of uniform dispersion of adhesive.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-axis precision transfer coating device, comprising a coating chamber, a base fixedly installed on the top of the coating chamber, guide rails fixedly installed on the front and rear sides of the base, a movable frame slidably installed on the guide rails, and a slider slidably installed inside the movable frame; A fixed frame is fixedly installed on the left side of the slider, and a cylinder is fixedly installed on the top of the fixed frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 7 As shown, this utility model provides a multi-axis precision transfer coating device, including a coating chamber 1, a base 2 fixedly installed on the top of the coating chamber 1, guide rails 3 fixedly installed on the front and rear sides of the base 2, a movable frame 4 slidably installed on the guide rails 3, and a slider 6 slidably installed inside the movable frame 4. A fixed frame 8 is fixedly installed on the left side of the slider 6. A cylinder 9 is fixedly installed on the top of the fixed frame 8. The telescopic end of the cylinder 9 extends through to the bottom of the fixed frame 8 and is fixedly installed on a fixed shell 10. A transfer wheel 14 is rotatably installed on the left side of the fixed shell 10. A glue pump 12 is fixedly installed inside the fixed shell 10. A storage chamber 11 is opened inside the fixed shell 10. One end of the glue pump 12 is connected to the storage chamber 11, and the other end of the glue pump 12 is connected to the transfer wheel 14. Multiple sets of drainage holes 15 are opened on the outer wall of the transfer wheel 14. A scraper 16 is fixedly installed on the outer wall of the fixed shell 10.

[0018] When adhesive application is required, the worker first places the workpiece on the rotating disk 19 for fixation. Then, the displacement of the transfer wheel 14 is controlled by the main control switch. At this time, the moving frame 4 can slide on the guide rail 3 via its bottom electric slider, thereby controlling the left and right displacement of the transfer wheel 14. The operation of motor 7 drives the screw 5 to rotate, thereby causing the screw 5 to move the slider 6 threadedly connected to it, further realizing the front and back displacement of the transfer wheel 14. Finally, the operation of cylinder 9 will drive the fixed shell 10 and the transfer wheel 14 to move up and down, realizing multi-axis adhesive application. During the application of adhesive, the operator can control the operation of the adhesive pump 12 through the master switch. The operation of the adhesive pump 12 will draw the adhesive from the storage chamber 11 into the transfer wheel 14. Finally, the adhesive will be laid on the outer surface of the transfer wheel 14 through the drain hole 15. At this time, the operation of the motor 2 17 will drive the gear 2 18 to rotate. The gear 2 18 and the gear 1 13 mesh with each other, so that the gear 1 13 drives the transfer wheel 14 to rotate. When the transfer wheel 14 rotates, the scraper 16 will scrape the adhesive on the surface of the transfer wheel 14 evenly, so that the adhesive can be evenly covered on the workpiece when the transfer wheel 14 is applying adhesive.

[0019] The transfer wheel 14 is moved left and right by the guide rail 3, moved back and forth by the screw 5, and moved up and down by the cylinder 9, thus realizing multi-axis glue application. Compared with traditional devices, this device can not only adjust multiple axes, but also evenly cover the surface of the transfer wheel 14 with glue through multiple sets of drainage holes 15, and spread evenly by the scraper 16, thereby improving the uniformity of the glue on the surface of the transfer wheel 14 and ensuring the glue application effect.

[0020] The movable frame 4 has a screw 5 rotatably mounted inside, and the screw 5 and the slider 6 are threadedly connected. The outer wall of the movable frame 4 is fixedly mounted with a motor 7, and the output shaft of the motor 7 is fixedly connected to the screw 5.

[0021] The operation of motor 7 drives screw 5 to rotate, and the rotation of screw 5 can drive slider 6 to move back and forth along the top of moving frame 4, and further, the transfer wheel 14 moves back and forth.

[0022] In this process, the glue pump 12 supplies glue that covers the surface of the transfer wheel 14 through the drain hole 15, and the scraper 16 and the transfer wheel 14 are in contact with each other.

[0023] The adhesive is spread evenly using the scraper 16 to ensure a good coating effect.

[0024] Among them, a gear 13 is fixedly installed on the right side of the transfer wheel 14, and a gear 2 18 is rotatably installed on the left side of the fixed shell 10. The gear 13 and the gear 2 18 mesh with each other.

[0025] The fixed housing 10 has a motor 2 17 fixedly installed inside it. The output shaft of the motor 2 17 passes through the front side of the fixed housing 10 and is fixedly connected to the gear 2 18.

[0026] Motor 2 17 drives gear 2 18 to rotate, which in turn drives gear 1 13 to rotate, causing the transfer wheel 14 to rotate and begin transferring the adhesive.

[0027] Among them, a rotating disk 19 is rotatably installed on the top of the base 2, and a fixed platform 20 is fixedly installed on both the left and right sides of the top of the rotating disk 19. A clamping plate 21 is movably installed at one end of the fixed platform 20, and a hand-tightening bolt 22 is threadedly connected to the middle of the fixed platform 20. The hand-tightening bolt 22 and the clamping plate 21 are rotatably connected.

[0028] When fixing the workpiece, the operator can rotate the two sets of hand-tightening bolts 22. Since the hand-tightening bolts 22 and the fixing table 20 are threaded together, the rotation of the two sets of fixing tables 20 will push the two sets of clamping plates 21 inward in a synchronized manner, further fixing the workpiece on the rotating disk 19.

[0029] Among them, a worm gear 25 is fixedly installed at the bottom of the rotating disk 19, a motor 24 is fixedly installed inside the base 2, a worm 23 is fixedly installed on the output shaft of the motor 24, and the worm 23 and the worm gear 25 are connected by transmission.

[0030] When applying adhesive to the workpiece, the operator can start motor 24. The operation of motor 24 will drive worm 23 to rotate. The rotation of worm 23 will drive worm wheel 25 connected to it to rotate, which will further cause the rotating disk 19 to rotate.

[0031] When the hand-tightening bolt 22 is rotated, the two sets of clamping plates 21 clamp the workpiece onto the rotating disk 19. The worm gear 23 is driven to rotate by the motor 24, which in turn drives the worm wheel 25 to rotate the rotating disk 19. Compared with traditional devices, this device can fix the workpiece while ensuring that the workpiece can be stably and thoroughly coated with glue by rotating the rotating disk 19, avoiding workpiece displacement and improving the glue coating quality.

[0032] Working principle and usage process of this utility model: When adhesive application is required, the worker first places the workpiece on the rotating disk 19 for fixation. Then, the displacement of the transfer wheel 14 is controlled by the main control switch. At this time, the moving frame 4 can slide on the guide rail 3 via its bottom electric slider, thereby controlling the left and right displacement of the transfer wheel 14. The operation of motor 7 drives the screw 5 to rotate, thereby causing the screw 5 to move the slider 6 threadedly connected to it, further realizing the front and back displacement of the transfer wheel 14. Finally, the operation of cylinder 9 will drive the fixed shell 10 and the transfer wheel 14 to move up and down, realizing multi-axis adhesive application. During the application of adhesive, the operator can control the operation of the adhesive pump 12 through the master switch. The operation of the adhesive pump 12 will draw the adhesive from the storage chamber 11 into the transfer wheel 14. Finally, the adhesive will be laid on the outer surface of the transfer wheel 14 through the drain hole 15. At this time, the operation of the motor 2 17 will drive the gear 2 18 to rotate. The gear 2 18 and the gear 1 13 mesh with each other, so that the gear 1 13 drives the transfer wheel 14 to rotate. When the transfer wheel 14 rotates, the scraper 16 will scrape the adhesive on the surface of the transfer wheel 14 evenly, so that the adhesive can be evenly covered on the workpiece when the transfer wheel 14 is applying adhesive.
