Description

Technical Field

[0001] This invention relates to the field of adhesive coating technology for parts, and in particular to a contour adhesive coating apparatus, system and method for spherical bearings. Background Technology

[0002] Spherical plain bearings are a type of spherical sliding bearing. Their basic structure includes an inner ring, an outer ring, and a bearing liner located between them for friction reduction. The bearing liner material is typically polytetrafluoroethylene (PTFE) composite material or other self-lubricating materials, bonded to the inner surface of the outer ring with adhesive. However, the inner surface of the outer ring has distinct characteristics: firstly, the adhesive application area is a ring-shaped or near-spherical cavity, with a narrow space and significant curvature variations; secondly, the spherical radius, opening size, cavity space, and coating area vary considerably among different specifications of spherical plain bearings, making it difficult for existing automated adhesive application devices to adapt quickly. Therefore, the following problems exist: the outer diameter of the adhesive applicator is significantly smaller than the inner diameter of the bore, easily leading to excessive adhesive thickness, and it is impossible to precisely pick up or absorb adhesive, resulting in uneven application. Furthermore, because the shape of the adhesive applicator is fixed, with the applicator section being a straight cylinder, it cannot be used for applying adhesive to the inner surface of the bearing outer ring. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a contour coating device, system and method for spherical plain bearings, which can automatically adapt to the curved contour of the inner surface of the outer ring of the spherical plain bearing, realize uniform and precise contour coating, and improve coating quality and production efficiency.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, a contour-applying adhesive device for spherical bearings includes: The frame is equipped with a liftable glue storage cylinder, as well as a rotating clamping mechanism and a glue pressing mechanism arranged coaxially with the glue storage cylinder; the glue storage cylinder is open at the top and has a detachable contouring glue applicator at the bottom, with glue holes evenly distributed on the contouring glue applicator, and the shape of the contouring glue applicator is adapted to the shape of the inner side of the outer ring of the bearing. The rotary clamping mechanism is located below the rubber storage cylinder, which can clamp the outer ring of the bearing and drive the outer ring of the bearing to rotate. The glue pressing mechanism is located above the glue storage cylinder and includes a liftable glue pressing rod. The lower end of the glue pressing rod extends through an opening into the glue storage cylinder and descends synchronously with the glue storage rod to press the glue out from the glue outlet of the conformal glue applicator.

[0005] As a further implementation, the clamping end of the rotary clamping mechanism is close to the contouring adhesive applicator head, and the clamping end is configured as a contouring jaw that can be centered and clamped, with the clamping surface of the contouring jaw being arc-shaped.

[0006] As a further implementation, a glue supply mechanism is also included. The glue supply mechanism is connected to the glue storage cylinder through a glue supply pipe. After each glue pressing rod presses the glue, a set amount of glue is added to the glue storage cylinder through the glue supply pipe.

[0007] As a further implementation, the glue storage cylinder is provided with racks on both sides and incomplete gears on both sides. The incomplete gears cooperate with the racks on the corresponding sides. The two sets of incomplete gears rotate in the same direction. The incomplete gear on one side drives the glue storage cylinder to descend, and the incomplete gear on the other side drives the glue storage cylinder to rise.

[0008] As a further implementation, the frame is also equipped with positioning gears, which are located on both sides of the glue storage cylinder and cooperate with the racks on the corresponding sides to realize the vertical lifting and lowering of the glue storage cylinder.

[0009] As a further implementation, the bottom of the contouring applicator is closed, the glue outlet is located on the side of the contouring applicator, and the top of the contouring applicator is integrated with the connecting part, which is detachably connected to the glue storage cylinder.

[0010] As a further implementation, the pressing mechanism includes a rotatable cam; a support rod is provided on the frame to restrict the vertical movement of the pressing rod, a spring is connected between the pressing rod and the support rod, and the cam can cooperate with the upper end of the pressing rod to push the pressing rod downward.

[0011] As a further implementation, the lower end of the pressure rod is connected to a pressure plate, the shape of which is adapted to the cross-sectional shape of the glue storage cylinder; Each time the pressure rod moves down, it presses out a set amount of glue from the glue outlet.

[0012] Secondly, a contouring adhesive application system for spherical bearings includes a contouring adhesive application device as described above, and a conveyor belt; the conveyor belt is located on one side of the contouring adhesive application device, and a bearing outer ring is conveyed on the conveyor belt. After the bearing outer ring is transferred to the contouring adhesive application device for adhesive application, it is carried away by the conveyor belt.

[0013] Thirdly, a contour-coating method for spherical plain bearings, employing any of the contour-coating devices described above, includes the following steps: Based on the shape of the inner side of the bearing outer ring, select the corresponding contour-following glue applicator and install it at the lower end of the glue reservoir. The rotary clamping mechanism clamps the outer ring of the bearing. The incomplete gear on one side of the glue storage cylinder drives the glue storage cylinder to descend. At the same time, the conformal glue application head extends into the outer ring of the bearing, and the glue pressing mechanism drives the glue pressing rod to press down, pressing out the set amount of glue in the glue storage cylinder through the glue outlet. Then, the rotary clamping mechanism drives the outer ring of the bearing to rotate, spreading the glue evenly. During the rotation of the outer ring of the bearing, the glue pressing rod rises first, and then the incomplete gear on the other side of the glue storage cylinder drives the glue storage cylinder to rise. The glue supply mechanism injects a set amount of glue into the glue storage cylinder.

[0014] The beneficial effects of the present invention are as follows: The present invention features a detachable, contour-following applicator head at the lower end of the glue reservoir. The head's shape is adapted to the inner surface of the bearing outer ring, enabling uniform glue application to the inner surface of this type of component, ensuring even coverage. The glue reservoir, in conjunction with a rotating clamping mechanism and a glue-pressing mechanism, enables automatic glue application to the inner surface of the bearing outer ring. After each dispensing of glue from the contour-following applicator head, the rotating clamping mechanism rotates the bearing outer ring, compressing and spreading the glue evenly onto its inner surface.

[0019] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0020] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a contouring adhesive applicator for spherical bearings includes a frame 1, on which a liftable adhesive storage cylinder 2, a rotating clamping mechanism 3, a driving mechanism 6, and an adhesive pressing mechanism 7 are provided. An adhesive supply mechanism 8 is provided on one side of the frame 1 for supplying adhesive to the adhesive storage cylinder 2.

[0021] like Figure 1 As shown, the glue pressing mechanism is located above the glue storage cylinder, and the rotary clamping mechanism 3 is located below the glue storage cylinder. The three are arranged coaxially. The frame 1 is provided with a support plate 4, and the rotary clamping mechanism 3 is installed on the support plate 4. The rotary clamping mechanism 3 can clamp the outer ring 5 of the bearing and drive the outer ring 5 of the bearing to rotate.

[0022] The glue storage cylinder 2 has an opening at the top and a detachable contoured glue applicator at the bottom. The contoured glue applicator has glue holes evenly distributed on it, and the shape of the contoured glue applicator is adapted to the shape of the inner side of the outer ring of the bearing. The pressure-pressing mechanism 7 includes a liftable pressure-pressing rod. The lower end of the pressure-pressing rod extends through an opening into the glue storage cylinder and can descend synchronously with the glue storage rod to press the glue out from the glue outlet 221 of the conformal glue applicator, thereby applying glue to the inner surface of the outer ring of the bearing.

[0023] The rotary clamping mechanism 3 preferably uses a rotary clamping cylinder. The clamping end of the rotary clamping cylinder is close to the contouring glue applicator 22. The clamping end is configured as a contouring jaw 31 that can be centered and clamped. The clamping surface of the contouring jaw 31 is arc-shaped to facilitate clamping the outer ring of the bearing.

[0024] The contouring gripper 31 can achieve final clamping of the bearing outer ring, ensuring that the clamped bearing outer ring 5 is coaxial with the glue reservoir 2. When the glue reservoir 2 drives the contouring glue applicator 22 to descend, the contouring glue applicator 22 can extend into the bearing outer ring along the correct descent path.

[0025] like Figures 2-4 As shown, a support frame (not shown in the figure) is provided on the frame 1, and two sets of drive motors are mounted on the support frame. The two sets of drive motors 61 are located on both sides of the glue storage cylinder 2.

[0026] Specifically, the glue storage cylinder 2 has racks 21 on both sides. The output ends of two sets of drive motors 61 are each connected to an incomplete gear 62. The two incomplete gears 62 are located on both sides of the glue storage cylinder and engage with the racks 21 on the same side. The two sets of drive motors 61 drive the two sets of incomplete gears 62 to rotate in the same direction, either clockwise or counterclockwise. Figure 3As shown, in this embodiment, the rotation is clockwise.

[0027] When the first incomplete gear 62 rotates to engage with the rack, its continued rotation causes the glue storage cylinder 2 to descend. When the first incomplete gear 62 disengages from the rack 21, the glue outlet 221 dispenses glue. Next, the rotating clamping mechanism 3 clamps the outer ring 5 of the bearing, causing it to rotate relative to the contour-applying glue head 22, evenly applying glue to the inner side of the outer ring 5. The next step is for the second incomplete gear 62 to rotate to engage with the rack 62 on the other side of the glue storage cylinder 2, thus causing the glue storage cylinder 2 to rise.

[0028] It is understandable that during the process of the glue storage cylinder 2 descending and rising, the glue pressing rod 74 of the glue pressing mechanism 7 completes one glue pressing process, that is, the conformal glue applicator 22 completes one glue dispensing. At the same time that the glue pressing rod 74 descends to its maximum limit, the first incomplete gear 62 just disengages from the rack 21.

[0029] In order to achieve stable vertical movement of the glue storage cylinder 2, such as Figure 3 As shown, a fixing plate 91 is provided on the frame above the drive motor 61. Two sets of fixing plates 91 are arranged opposite each other. A positioning gear 92 is installed between the two sets of fixing plates 91 through a connecting shaft. Two sets of positioning gears 92 are arranged on both sides of the glue storage cylinder and each of them is engaged with the corresponding rack.

[0030] Since the two incomplete gears 62 cannot simultaneously engage with the rack on the glue storage cylinder 2 through their teeth, a positioning gear 92 is added to ensure that the glue storage cylinder 2 moves up and down in the vertical direction.

[0031] like Figure 2 , Figure 5 and Figure 6 As shown, a set of mounting plates is provided at the top of the frame, and a glue pressing mechanism 7 is provided in the middle of the mounting plates. The glue pressing mechanism 7 includes a glue pressing motor 71, a support rod 72, a limit sleeve 721, a cam 73, a glue pressing rod 74, a glue pressing plate 741, and a spring 75.

[0032] The pressure-pressing motor 71 is fixed to one side of the mounting plate, and a support rod 72 is vertically installed on the other side of the mounting plate. The support rod is equipped with a limiting sleeve 721, which has a rectangular frame structure. The pressure-pressing rod 74 also has a rectangular cross-section, is also vertically arranged, and passes through the limiting sleeve 721. Under the restriction of the limiting sleeve 721, it can only move vertically up and down.

[0033] The shaft of the pressure motor 71 passes through the mounting plate and the support rod 72 and is connected to a set of cams 73. The cams can cooperate with the top of the pressure rod 74 to push the pressure rod down.

[0034] Furthermore, such as Figure 5As shown, a spring 75 is connected between the limiting sleeve 721 and the pressure rod 74. One end of the spring 75 is connected to the limiting sleeve 721, and the other end is connected to the pressure rod 74.

[0035] As cam 73 rotates, it presses down on the top of the pressure rod 74, causing the pressure rod 74 to descend and the spring 75 to be stretched. When cam 73 pushes the pressure rod 74 down to its lowest position, the glue dispensing process is completed. At this point, the first incomplete gear 62 just disengages from the rack 21, while the second incomplete gear 62 has not yet begun to engage with the rack. At this time, both incomplete gears 62 are in an unengaged state with the rack. As cam 73 continues to rotate, it stops pressing down on the pressure rod 74, and the pressure rod 74 rises under the action of the spring 75.

[0036] like Figure 6 As shown, the bottom end of the pressure rod 74 is connected to a set of pressure plates 741. The shape of the pressure plates 741 is adapted to the cross-sectional shape of the glue storage cylinder 2. The pressure plates 741 are circular plate structures.

[0037] The pressure plate 741 has a ring of rubber around its perimeter, which fits against the inner side of the glue storage cylinder 2. Pressing down on the pressure plate 741 can force the glue in the glue storage cylinder 2 out from the glue outlet of the conformal applicator head 22. It can be understood that the glue fills the space below the pressure plate 741 inside the glue storage cylinder.

[0038] Understandably, each time the pressure rod 74 moves down, it presses out a set amount of glue from the glue outlet 221. The amount of glue dispensed is the amount required for the inner surface of each bearing outer ring 5, which has been tested and verified.

[0039] like Figure 1 As shown, it also includes a glue supply mechanism 8, which is connected to a glue storage cylinder 2 via a glue supply pipe 81. The glue supply pipe 81 is connected to the glue storage cylinder 2 and can fill the glue into the position below the pressure rod inside the glue storage cylinder 2.

[0040] It is understandable that the glue supply mechanism 8 can adopt existing technology, including a glue storage tank, which pumps glue into the glue storage cylinder 2 via a pump. The amount of glue supplied each time is the amount required for one application. Therefore, after each application by the glue pressing rod 74, a set amount of glue needs to be added to the glue storage cylinder 2 through the glue supply pipe.

[0041] It is understandable that after the pressure rod 74 rises, the glue storage space between the pressure plate 741 and the glue storage cylinder 2 is not completely vacuumed, so it does not affect the glue replenishment work.

[0042] like Figure 7As shown, the bottom of the contour applicator 22 is closed, the glue outlet 221 is located on the side of the contour applicator 22, the top of the contour applicator 22 is connected to the connecting part 222 as a whole, and it is detachably connected to the glue storage cylinder 2 through the connecting part 222. The connecting part 222 can be set as an annular body with internal threads, and external threads are provided at the lower end of the glue storage cylinder 2, so that the contour applicator 22 is threadedly fixed on the glue storage cylinder 2.

[0043] The contour applicator 22 is detachably connected to the glue reservoir 2 via the connector 222, allowing for the selection of a suitable contour applicator 22 based on the shape of the bearing outer ring.

[0044] The contouring applicator 22 is shaped like a bowl. It should be noted that the contouring applicator 22 in this embodiment is suitable for cases where the inner surface of the bearing outer ring decreases from top to bottom. If the inner surface of the bearing outer ring 5 is large in the middle and small at both ends, then the solution of this application is not suitable.

[0045] The shape of the contouring applicator 22 is perfectly matched with the inner surface of the bearing outer ring 5. This is to solve the problem that the outer diameter of the applicator is much smaller than the inner diameter of the hole (the inner hole of the bearing outer ring), which can easily lead to excessive glue thickness.

[0046] Furthermore, since the adhesive dispensing holes 221 are evenly distributed in multiple layers along the circumference of the contour applicator head 22, with each layer having the same quantity, the adhesive appears as dots on the inner surface of the bearing outer ring 5 after dispensing. The next step requires rotating the clamping mechanism 3 to rotate the bearing outer ring 5, scraping away the dots of adhesive and spreading them evenly. As the contour applicator head 22 rotates relative to the inner surface of the bearing outer ring 5, and there is a certain squeezing effect between them, the dots of adhesive can be spread evenly.

[0047] In another preferred example, the glue outlets 221 are evenly distributed in a quincunx pattern on the sidewalls surrounding the contouring glue applicator 22, ensuring more uniform glue application.

[0048] The cross-section of the glue outlet 221 is circular. Furthermore, based on the plum blossom-shaped arrangement of the glue outlet 221, the radius of the glue outlet 221 increases from the inside to the outside, so that when the glue is dispensed from the inside of the conformal glue applicator 22 through the glue outlet to the inner surface of the outer ring of the bearing, the glue can be diffused, further ensuring uniform glue application.

[0049] Example 2 like Figures 1-7 As shown, in a typical embodiment of the present invention, a contour coating system for spherical bearings includes the contour coating device described in Embodiment 1, and also includes a conveyor belt; the conveyor belt includes an incoming material conveyor belt and a feeding conveyor belt, which are arranged independently.

[0050] The incoming conveyor belt is used to transport the bearing outer ring 5 that needs to be coated to the contour coating device, and the outgoing conveyor belt is used to send the coated bearing outer ring 5 away. The incoming material conveyor belt and the feeding conveyor belt are located on one side of the conformal coating device. The positions of the two sets of conveyor belts can be adjusted according to actual operation to ensure convenient operation.

[0051] When the incoming conveyor belt delivers the bearing outer ring to the conformal gluing device, the worker picks up the bearing outer ring and places it on the rotary clamping mechanism 3. After the gluing is completed, the rotary clamping mechanism 3 releases the bearing outer ring, and the worker transfers the bearing outer ring to the feeding conveyor belt to be sent away.

[0052] In a preferred example, a set of robotic arms can also be set up near the contour coating device as needed. The robotic arms replace manual labor to transfer the outer ring 5 of the bearing between the two sets of conveyor belts and the contour coating device.

[0053] Understandably, the contouring adhesive applicator is equipped with a controller. The controller is set with control logic, and the frame can be equipped with corresponding vision sensors. After recognizing that the outer ring of the bearing is placed on the rotating clamping mechanism 3, the outer ring of the bearing is automatically clamped. Then the controller controls the drive motor 61 and the adhesive pressing motor 71 to work accordingly to realize automatic adhesive application.

[0054] After the adhesive application is completed, the rotating clamping mechanism 3 releases the bearing outer ring 5, and the bearing outer ring 5 is transferred to the feeding conveyor belt to continue applying adhesive to the next bearing outer ring 5. Before applying adhesive to the next bearing outer ring 5, the controller controls the adhesive supply mechanism to add adhesive, so that the amount of adhesive dispensed is the same each time the pressure rod 74 descends to the designated position, ensuring that the amount of adhesive applied to each bearing is the same and improving product quality.

[0055] Understandably, when robotic arms replace manual labor, one set of robotic arms can lift the outer ring 5 of the bearing from the incoming conveyor belt onto the rotary clamping mechanism 3, while another set of robotic arms lifts the outer ring 5 from the rotary clamping mechanism 3 onto the feeding conveyor belt. The two sets of robotic arms work together to improve efficiency. Furthermore, in this working state, by adjusting the rotation speed of each motor output, the drive motor 61 and the adhesive pressing motor 71 can be continuously powered. Under the control of the controller, the rotary clamping mechanism 3 and the robotic arms can seamlessly connect their respective workflows, thereby enabling automatic adhesive application to the inner surface of the bearing outer ring.

[0056] Example 3 This embodiment discloses a contour-coating method for spherical plain bearings, such as... Figures 1-7 As shown, it uses the contour-following adhesive application device of Embodiment 1, and includes the following steps: First, based on the shape of the inner side of the outer ring 5 of the bearing, a corresponding contour applicator 22 needs to be selected and threaded onto the lower end of the glue reservoir 2 to ensure that the shape of the contour applicator 22 matches the shape of the inner side of the outer ring 5 of the bearing.

[0057] When the outer ring 5 of the bearing approaches the conformal coating device under the action of the conveyor belt, the outer ring 5 of the bearing is gripped onto the rotary clamping mechanism 3. The rotary clamping mechanism 3 clamps the outer ring 5 of the bearing in the center. After being clamped, the outer ring 5 of the bearing is coaxial with the glue storage cylinder 2 and is positioned directly below it.

[0058] Two sets of drive motors 61 drive the incomplete gears to work. The teeth on the incomplete gear 62 on one side begin to engage with the rack, causing the glue storage cylinder 2 to descend. The contouring glue applicator 22 extends into the outer ring 5 of the bearing. At the same time, the cam 73 rotates, causing the pressure rod 74 to press down. The shape of the cam 73 is designed (adjusting the tilt of the cam profile) so that when the contouring glue applicator 22 descends to the position where glue needs to be dispensed, the pressure plate 741 of the pressure rod 74 can quickly press down the glue, pressing out the set amount of glue from the glue outlet of the contouring glue applicator 22. The pressure rod 74 reaches its maximum stroke. Then, under the action of the cam and the spring, the pressure rod begins to rise. At this time, the incomplete gear 62 on the first side is disengaged from the rack, while the incomplete gear 62 on the second side has not yet engaged with the rack 21.

[0059] Next, the rotary clamping mechanism 3 drives the bearing outer ring 5 to rotate, achieving uniform application of adhesive to the inner surface of the bearing outer ring. This completes the adhesive application to the inner surface of one bearing outer ring 5. During this process, neither of the two incomplete gears 62 meshes with the rack 21. The adhesive storage cylinder 2, under the influence of gravity, is at its lowest point. After the rotary clamping mechanism 3 completes the rotation of the bearing outer ring 5, the second incomplete gear 62 begins to mesh with the rack 21, subsequently causing the adhesive storage cylinder 2 to rise, and the contouring adhesive application head 22 disengages from the bearing outer ring 5. Then, the controller controls the rotary clamping mechanism to release the bearing outer ring, which can be transferred manually or by a robotic arm onto a conveyor belt for transport.

[0060] When the glue reservoir 2 rises, the pressure rod has already risen as the outer ring 5 of the bearing rotates. Therefore, during the rising process of the glue reservoir 2, the glue will not be squeezed out again.

[0061] By adjusting the tilt of the cam profile, the glue storage cylinder can quickly perform a glue pressing operation when the pressing rod reaches its maximum stroke after each descent. After that, when the pressing rod 74 starts to rise, the glue storage cylinder needs to wait for the rotating clamping mechanism 3 to drive the outer ring of the bearing to rotate at the lowest point before being driven to rise by the incomplete gear 62 on the other side. This ensures that the pressing rod will not press out the glue when the glue storage cylinder rises.

[0062] In this embodiment, the teeth on the incomplete gear 62 are configured such that when the teeth on one side of the incomplete gear 62 disengage from the glue storage cylinder 2, the glue storage cylinder 2 is in its lowest state. Meanwhile, the incomplete gear 62 on the other side continues to rotate, but the teeth do not begin to engage with the rack until the rotating clamping mechanism 3 drives the outer ring of the bearing to rotate, at which point the engagement state begins, causing the glue storage cylinder to rise.

[0063] The cam's structural configuration must satisfy the following conditions: the pressure rod 74 and the glue storage cylinder 2 reach the lowest point synchronously for glue dispensing. Afterward, when the rotating clamping mechanism 3 drives the outer ring of the bearing to rotate, the pressure rod 74 has already started to rise. When the glue storage cylinder 2 starts to fall again, the pressure rod 74 also begins to fall.

[0064] After each dispensing of adhesive, and before the next dispensing, the controller needs to control the adhesive supply mechanism to inject the set amount of adhesive into the adhesive storage cylinder 2. Since the stroke of the pressure rod 74 and the adhesive storage cylinder 2 is fixed, after each application of adhesive, the adhesive supply mechanism 8 needs to add the set amount of adhesive into the adhesive storage cylinder 2 to ensure that the amount of adhesive dispensed each time is the same. When switching the model of the bearing outer ring, the amount of adhesive added needs to be adjusted.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

10. A contour-coating method for spherical plain bearings, characterized in that, The contour coating apparatus as described in any one of claims 1-8 includes the following steps: Based on the shape of the inner side of the bearing outer ring, select the corresponding contour-following glue applicator and install it at the lower end of the glue reservoir. The rotary clamping mechanism clamps the outer ring of the bearing. The incomplete gear on one side of the glue storage cylinder drives the glue storage cylinder to descend. At the same time, the conformal glue application head extends into the outer ring of the bearing, and the glue pressing mechanism drives the glue pressing rod to press down, pressing out the set amount of glue in the glue storage cylinder through the glue outlet. Then, the rotary clamping mechanism drives the outer ring of the bearing to rotate, spreading the glue evenly. During the rotation of the outer ring of the bearing, the glue pressing rod rises first, and then the incomplete gear on the other side of the glue storage cylinder drives the glue storage cylinder to rise. The glue supply mechanism injects a set amount of glue into the glue storage cylinder.
