Description

Technical Field

[0001] The utility model relates to the technical field of glue coating devices, in particular to a glue coating machine for coating the inner wall of a roller. Background Art

[0002] An electric roller is a new type of driving device, usually applied to logistics automation equipment for conveying items. The electric roller includes a main shaft, a roller, and an electric motor. Among them, the stator of the electric motor is fixedly connected to the main shaft, the roller is sleeved on the main shaft, and a magnetic steel is fixed on the inner wall of the roller, so that the roller forms the rotor of the electric motor. When the stator of the electric motor is energized with alternating current, a magnetic field is formed to drive the roller to rotate around the main shaft. During the assembly of the electric roller, it is necessary to first apply glue on the inner wall of the roller through a glue coating machine, and then bond the magnetic steel on the inner wall of the roller.

[0003] There are two types of glue coating machines in the prior art. One type of glue coating machine uses a glue needle to throw glue on the inner wall of the roller and then bond the magnetic steel. The glue output of this type of glue coating machine is unstable and the coating is uneven, resulting in unreliable bonding of the magnetic steel. The other type of glue coating machine uses a brush to brush glue on the inner wall of the roller and then bond the magnetic steel. The disadvantage of this type of glue coating machine is that when the brush is not in use, the glue will gradually solidify, causing the brush to harden, and the residual glue is not easy to clean, which affects the reuse. Summary of the Utility Model

[0041] Please refer to Figures 1 to 3 , this embodiment provides a glue applicator, which is used to apply glue to the inner wall of a roller 9. The glue applicator includes an operating table 1, a support column 2, a rotary drive mechanism 3, a glue brushing mechanism 4 and a moving drive mechanism 6. Among them, the support column 2 is fixed on the operating table 1, and the support column 2 extends along a first direction (such as Figure 1extends in the direction indicated by arrow ab; the rotation driving mechanism 3 is installed on the operation table 1, and the rotation driving mechanism 3 is used to support the roller 9 and can drive the roller 9 to rotate around its own axis, and the axis of the roller 9 extends along the first direction; the glue application mechanism 4 includes a fixed seat 41 slidably connected to the support column 2 along the first direction, and a glue application assembly 42 provided on the fixed seat 41. The glue application assembly 42 includes a glue bucket 43, a glue pipe 44 and a glue head 45. The glue bucket 43 is used to hold glue. The first end of the glue pipe 44 is communicated with the glue bucket 43, the second end of the glue pipe 44 faces the glue head 45, and the glue pipe 44 is used to guide the glue in the glue bucket 43 to the glue head 45. The glue head 45 is made of silica gel material; the moving driving mechanism 6 is in transmission connection with the fixed seat 41, and the moving driving mechanism 6 is used to drive the fixed seat 41 to reciprocate along the first direction so that the glue head 45 can extend into or withdraw from the inside of the roller 9. When the glue applicator provided in this embodiment is working, the moving driving mechanism 6 drives the fixed seat 41 to move along the first direction. The fixed seat 41 drives the glue head 45 to move synchronously and makes the glue head 45 extend into the roller 9. The rotation driving mechanism 3 drives the roller 9 it supports to rotate. The glue in the glue bucket 43 flows through the glue pipe 44 to the glue head 45 and is then applied to the inner wall of the roller 9 by the glue head 45. Since the silica gel material has a certain hardness, the glue can be reliably and evenly applied to the inner wall of the roller 9; and when the glue applicator is not in use, the residual glue on the glue head 45 can be conveniently wiped off for reuse.

[0042] Optionally, in this embodiment, the first direction is the vertical direction. Specifically, when the roller 9 is supported by the rotation driving mechanism 3, the axis of the roller 9 is along the vertical direction. Correspondingly, the support column 2 extends along the vertical direction, the fixed seat 41 is slidably connected to the support column 2 along the vertical direction, and the moving driving mechanism 6 can drive the fixed seat 41 to reciprocate along the vertical direction so that the glue head 45 can extend into or withdraw from the inside of the roller 9. In other embodiments, the first direction can also be other directions forming an angle with the vertical direction, such as the horizontal direction. Taking the first direction as the horizontal direction as an example, at this time, when the roller 9 is supported by the rotation driving mechanism 3, the axis of the roller 9 is along the horizontal direction. Correspondingly, the support column 2 extends along the horizontal direction, the fixed seat 41 is slidably connected to the support column 2 along the horizontal direction, and the moving driving mechanism 6 can drive the fixed seat 41 to reciprocate along the horizontal direction so that the glue head 45 can extend into or withdraw from the inside of the roller 9.

[0043] Optionally, the glue brushing assembly 42 is located above the rotary drive mechanism 3, and the glue barrel 43, the rubber hose 44 and the rubber head 45 are arranged in sequence in the vertical direction, so that the glue in the glue barrel 43 can flow downward along the rubber hose 44 under its own gravity and be guided to the rubber head 45. In other embodiments, the glue barrel 43 is connected to a pressurizing device, the glue barrel 43 has a receiving chamber for receiving glue, the pressurizing device is used to pressurize the receiving chamber, the first end of the rubber hose 44 is connected to the receiving chamber, and the air pressure in the receiving chamber is increased by the pressurizing device, which can promote the glue in the glue barrel 43 to enter the rubber hose 44. By adopting the pressurizing device, the spatial position of the glue barrel 43 and the rubber hose 44 can be set according to actual needs, and is no longer limited to being set in sequence in the vertical direction. Among them, the pressurizing device can be a piston, the piston is located in the receiving chamber, and the piston and the cavity wall of the receiving chamber are slidably matched; or the pressurizing device is a high-pressure gas source, and the high-pressure gas source is connected to the top of the receiving chamber.

[0044] Optionally, see Figure 2 The mobile drive mechanism 6 includes a drive motor 61 and a linear transmission module 62. The drive motor 61 is fixed to the support column 2. The drive motor 61, the linear transmission module 62 and the fixed seat 41 are sequentially connected in transmission connection, and the drive motor 61 drives the fixed seat 41 to move along the first direction through the linear transmission module 62. Specifically, in the present embodiment, the drive motor 61 drives the fixed seat 41 to move in the vertical direction through the linear transmission module 62. Preferably, the linear transmission module 62 includes two pulleys spaced apart in the vertical direction and a transmission belt sleeved on the two pulleys. One of the two pulleys is connected in transmission connection with the drive motor 61, and the fixed seat 41 is fixedly connected with the transmission belt. The drive motor 61 drives the pulley to rotate, and the pulley drives the transmission belt to move, and the fixed seat 41 is driven to move in the vertical direction through the transmission belt. In other embodiments, the linear transmission module 62 includes a screw rod rotatably set on the support column 2, and a nut threadedly connected to the screw rod. The drive motor 61 is transmission connected to the screw rod, the nut and the support column 2 slide together in the vertical direction, and the fixed seat 41 is fixedly set on the nut. The drive motor 61 drives the screw rod to rotate, and the rotation of the screw rod causes the nut to drive the fixed seat 41 to move synchronously in the vertical direction relative to the support column 2.

[0045] Optionally, see Figure 2, the rotation drive mechanism 3 includes a rotation motor 31 and a rotating cylinder 32. The rotation motor 31 is installed on the operation table 1. The output shaft of the rotation motor 31 extends in the first direction. The rotating cylinder 32 is fixedly connected to the output shaft of the rotation motor 31. The rotating cylinder 32 is used to support the roller 9 and drive the roller 9 to rotate around its own axis. Wherein, the inner diameter of the rotating cylinder 32 matches the outer diameter of the roller 9. One end of the roller 9 is inserted into the rotating cylinder 32, and the roller 9 and the rotating cylinder 32 are coaxial. When the output shaft of the rotation motor 31 rotates, the rotation motor 31 drives the rotating cylinder 32 to rotate, so that the roller 9 rotates synchronously around its own axis. Specifically, in this embodiment, the rotation motor 31 is installed below the operation table 1, and the rotating cylinder 32 is located above the operation table 1.

[0046] Optionally, the rotation drive mechanism 3 further includes a clamping mechanism fixedly connected to the rotating cylinder 32. The clamping mechanism includes a plurality of clamping members 33. The plurality of clamping members 33 are evenly distributed along the circumferential direction of the rotating cylinder 32. The clamping members 33 are used to clamp the roller 9 so that the relative position of the roller 9 and the rotating cylinder 32 can be kept stable, ensuring that the rotating cylinder 32 can drive the roller 9 to rotate synchronously when rotating. Among them, in this embodiment, a scheme in which the clamping mechanism includes two clamping members 33 is exemplarily given. In other embodiments, the number of the clamping members 33 can also be set as needed. Preferably, the clamping member 33 is a quick chuck.

[0047] Optionally, please refer to Figure 4 and Figure 5 , in this embodiment, the rubber head 45 includes a rubber head body 451, a glue storage groove 452 and a glue scraping part 455 which are sequentially arranged on the rubber head body 451 along the circumferential direction of the roller 9. The glue storage groove 452 and the glue scraping part 455 both extend in the vertical direction, and the upper end opening of the glue storage groove 452 is opposite to the lower end opening of the rubber tube 44, and the side opening of the glue storage groove 452 is opposite to the inner wall of the roller 9. The glue scraping part 455 is used to scrape the glue on the inner wall of the roller 9. When the rubber head 45 extends into the roller 9, the glue scraping part 455 can scrape the glue on the inner wall of the roller 9 during the rotation of the roller 9. With such a setting, when the rubber head 45 extends into the roller 9, the glue in the glue bucket 43 flows into the glue storage groove 452 through the rubber tube 44 and slowly flows downward along the glue storage groove 452. At this time, the rotation drive mechanism 3 drives the roller 9 to rotate, so that the glue can be coated on the inner wall of the roller 9; at the same time, the excessive glue coated on the inner wall of the roller 9 is scraped off by the glue scraping part 455 to ensure that the thickness of the glue coated on the inner wall of the roller 9 is uniform.

[0048] It can be understood that when the rubber head 45 extends into the roller 9, there is a set gap between the glue scraping part 455 and the inner wall of the roller 9, and this set gap is the required thickness of the glue to be applied on the inner wall of the roller 9. However, when the glue in the glue containing groove 452 is applied to the inner wall of the roller 9, the actual thickness of the glue applied to the inner wall of the roller 9 may exceed the required thickness or be less than the required thickness. During the rotation of the roller 9, the glue scraping part 455 can scrape the glue exceeding the required thickness to the required thickness, and the excess glue will be pushed by the glue scraping part 455 to move forward. When it encounters a place where the actual thickness of the applied glue is less than the required thickness, the excess glue pushed forward by the glue scraping part 455 can be filled to make the actual thickness of the glue up to the required thickness, so as to ensure that the thickness of the glue applied on the inner wall of the roller 9 is uniform.

[0049] Optionally, please refer to Figure 5 , the rubber head body 451 is in the shape of a cuboid, including two first end faces 456 arranged along the second direction (such as the direction indicated by the cd arrow in Figure 1 ), and two second end faces 457 arranged along the first direction. The glue containing groove 452 and the glue scraping part 455 are both arranged on the same first end face 456. The lower end of the rubber tube 44 is adjacent to the upper second end face 457 among the two second end faces 457. Among them, the first direction and the second direction are arranged at an angle. In this embodiment, the first direction is the vertical direction and the second direction is the horizontal direction.

[0050] Optionally, please refer to Figure 5 , the rubber head 45 includes two glue scraping parts 455. Along the circumferential direction of the roller 9, the two glue scraping parts 455 are respectively located on both sides of the glue containing groove 452. With such a setting, when the roller 9 rotates forward, one of the glue scraping parts 455 can scrape off the excessive glue applied on the inner wall of the roller 9 to ensure that the thickness of the glue applied on the inner wall of the roller 9 is uniform; when the roller 9 rotates reversely, the other glue scraping part 455 can scrape off the excessive glue applied on the inner wall of the roller 9 to ensure that the thickness of the glue applied on the inner wall of the roller 9 is uniform. Further optionally, the two glue scraping parts 455 are symmetrically arranged with respect to the glue containing groove 452.

[0051] Optionally, please refer to Figure 4, the cross-section of the glue scraping part 455 is arc-shaped, and the cross-sections of the two glue scraping parts 455 coincide with the same arc surface 458. The glue containing groove 452 is opened in the middle of the arc surface 458, and the cross-section of the glue containing groove 452 is an arc-shaped groove concave towards the center of the arc surface 458. With such a setting, when the glue head 45 is inserted into the drum 9, the gap between the glue scraping part 455 and the inner wall of the drum 9 can be kept uniform, and the contact area between the glue scraping part 455 and the glue during glue scraping is small, which can ensure the stable and reliable glue scraping effect. And the glue containing groove 452 is centrally arranged between the two glue scraping parts 455. Whether the drum 9 rotates forward or backward, the excess glue scraped off is always restricted in the glue containing groove 452, ensuring the stable glue scraping effect.

[0052] Optionally, please refer to Figure 5 , in this embodiment, the glue containing groove 452 includes a conical groove 453 and a cylindrical groove 454 connected in sequence along the vertical direction. The upper opening of the conical groove 453 is larger than the lower opening of the conical groove 453. The upper opening of the conical groove 453 faces the lower opening of the rubber tube 44. The lower opening of the conical groove 453 is communicated with the upper opening of the cylindrical groove 454, and the side opening of the glue containing groove 452 is communicated with the cylindrical groove 454. With such a setting, the glue in the rubber tube 44 flows into the conical groove 453 from the upper opening of the conical groove 453, and then flows into the cylindrical groove 454 under the guidance of the conical groove 453. Since the opening aperture at the upper end of the conical groove 453 is the largest, the glue flowing out of the rubber tube 44 flows into the conical groove 453 through the upper opening of the conical groove 453, which can prevent the glue from overflowing to other parts of the glue head 45 after flowing out of the rubber tube 44 and causing pollution. Preferably, the lower opening of the rubber tube 44 extends into the conical groove 453 from the upper opening of the conical groove 453.

[0053] Optionally, please refer to Figure 5 and Figure 6, the glue brushing mechanism 4 further includes a first clamping block 46 and a second clamping block 47. The first clamping block 46 includes a first clamping surface 461 and a first groove 462 spaced along a first direction. The second clamping block 47 includes a second clamping surface 471 and a second groove 472 spaced along the first direction. The first clamping surface 461 and the second clamping surface 471 are oppositely arranged to clamp the glue head 45, and the first groove 462 and the second groove 472 are docked to clamp the glue pipe 44. With such an arrangement, through the cooperation of the first clamping block 46 and the second clamping block 47, the glue head 45 and the glue pipe 44 can be fixed simultaneously to ensure the relative position stability of the glue head 45 and the glue pipe 44, and further ensure that the second end of the glue pipe 44 is opposite to the glue head 45, so that the glue can flow reliably into the glue containing groove 452. Specifically, the glue head body 451 of the glue head 45 is clamped between the first clamping block 46 and the second clamping block 47, and the glue scraping part 455 and the glue containing groove 452 protrude outside the first clamping block 46 and the second clamping block 47. Thus, when the glue head 45 extends into the roller 9, the glue in the glue containing groove 452 can contact the inner wall of the roller 9, and the glue scraping part 455 can scrape off the excess glue on the inner wall of the roller 9 and prevent the first clamping block 46 and the second clamping block 47 from affecting the glue application and glue scraping operations.

[0054] Specifically, in this embodiment, the glue brushing mechanism 4 further includes a plurality of fasteners.
