For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] The following is for reference. Figures 1-5 A putty scraping device 100 according to an embodiment of the present invention is described.

[0048] like Figure 1 and Figure 2 As shown, the putty scraping device 100 according to an embodiment of the present invention includes a support assembly 1, a drive component 2, a rotating shaft 3, a roller 4, and a putty box 5.

[0049] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the drive unit 2 is mounted on the support assembly 1, the rotating shaft 3 is rotatably mounted on the support assembly 1 and connected to the output shaft of the drive unit 2, the roller 4 is rotatably sleeved on the rotating shaft 3, the putty box 5 is mounted on the support assembly 1, the putty box 5 has an upper open cavity 51 for containing putty, and the lower part of the roller 4 is located in the cavity 51. The axial direction and the vertical direction of the rotating shaft 3 are perpendicular to each other.

[0050] Both the drive component 2 and the rotating shaft 3 are mounted on the bracket assembly 1. The drive component 2 can provide a continuous and stable torque force and drive the rotating shaft 3 to rotate through the output shaft. The roller 4 is mounted on the rotating shaft 3. Thus, the drive component 2 can provide a stable and efficient driving force for the rotation of the roller 4. There is no need for manual rotation or movement of the roller 4, which reduces the need for manual operation, thereby reducing labor costs and improving control and operation accuracy.

[0051] Furthermore, the cavity 51 at the upper end of the putty box 5 contains putty, and the lower part of the roller 4 is located inside the cavity 51. Therefore, when the drive unit 2 drives the roller 4 to rotate, the putty inside the cavity 51 adheres to the lower part of the roller 4 and rotates with it. At this time, it is only necessary to control the workpiece 9 (e.g., irregularly shaped components) to contact the roller 4, so that the surface of the workpiece 9 is pressed against the surface of the roller 4 and rolls relative to it. The putty on the roller 4 is thus applied to the workpiece 9. This reduces the difficulty of operation, thereby improving production efficiency and quality. Moreover, controlling the contact between the workpiece 9 and the roller 4 is simple. Figure 5 As shown in the example, automated equipment such as robots or robotic arms can replace manual operations, which is conducive to achieving automated control and production, thereby reducing the intensity of human labor and effectively improving production efficiency and quality.

[0052] According to an embodiment of the present invention, the putty scraping device 100 is provided on the support assembly 1 with a drive member 2, a putty box 5 and a rotating shaft 3 passing through the roller 4, and the rotating shaft 3 is connected to the output shaft of the drive member 2. At the same time, the lower part of the roller 4 is located in the cavity 51 at the upper end of the putty box 5. The drive member 2 can stably and efficiently drive the roller 4 to rotate. When the roller 4 rotates, it continuously adheres to the putty in the cavity 51 and applies it to the workpiece 9 to be processed in contact with the roller 4. The operation is simple and can help to replace manual operation with automated equipment. It can reduce the intensity of manual labor and improve the operation accuracy, thereby improving production efficiency and product quality.

[0053] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the bottom wall of the cavity 51 includes a first bottom wall 511 and a second bottom wall 512. The first bottom wall 511 and the second bottom wall 512 are arranged along a first direction. The first bottom wall 511 is an arc surface coaxial with the roller 4. Along the radial direction of the rotating shaft 3, the roller 4 is spaced apart from the first bottom wall 511. In the direction from the second bottom wall 512 to the first bottom wall 511, the second bottom wall 512 is inclined downward. At least a portion of the second bottom wall 512 is spaced apart from the roller 4 in the first direction. The first direction, the axial direction of the rotating shaft 3, and the up-down direction are all perpendicular to each other.

[0054] In the first direction, the length of the cavity 51 is greater than the outer diameter of the roller 4. The roller 4 is opposite to the first bottom wall 511 and part of the second bottom wall 512. The upper open end of the cavity 51 opposite to the part of the second bottom wall 512 is not blocked by the roller 4 and can serve as an inlet for putty to be put into the cavity 51. The second bottom wall 512 is an inclined surface and has a guiding function, which can guide the putty put into the cavity 51 toward the first bottom wall 511, thereby facilitating full contact between the rotating roller 4 and the putty inside the cavity 51.

[0055] Furthermore, part of the bottom wall of the cavity 51 is configured as a first bottom wall 511 with an arc surface, and the first bottom wall 511 is coaxial with the roller 4. As the roller 4 rotates, the putty can be brought between the roller 4 and the first bottom wall 511. Under the pressure of the roller 4 and the first bottom wall 511, the putty can be more firmly adhered to the outer peripheral wall of the roller 4. At the same time, it can also avoid dead corners where putty accumulates on the first bottom wall 511, so that the putty output is constant and controllable, thereby improving the utilization rate of putty in the cavity 51.

[0056] Preferably, the plane of the second bottom wall 512 is tangent to the cylindrical surface of the first bottom wall 511. In this way, the first bottom wall 511 and the second bottom wall 512 can form a better fit with the roller 4. The inclined second bottom wall 512 guides the putty to the junction of the first bottom wall 511 and the second bottom wall 512. The roller 4 rotates and picks up the putty, which can make full use of the putty in the cavity 51 and further improve the utilization rate of the putty in the putty box 5.

[0057] In some embodiments of the present invention, such as Figure 2 , Figure 3 and Figure 4 As shown, the putty scraping device 100 also includes a putty scraper 52, which is located on the upper side of the putty box 5 and opposite to the second bottom wall 512. One end of the putty scraper 52 is connected to the putty box 5, and the other end extends toward the roller 4 to scrape off excess putty on the roller 4.

[0058] It is understandable that the putty scraper 52 and the roller 4 are arranged along the first direction and spaced apart along the first direction. During the rotation of the roller 4, the lower end of the roller 4 is covered with putty and rotates towards the putty scraper 52. When it rotates to the putty scraper 52, the putty scraper 52 can scrape off the excess putty stuck on the roller 4 and make the putty drip back into the cavity 51. This can avoid too much putty sticking to the roller 4 and can improve the thickness uniformity of the putty stuck on the roller 4, thereby improving the uniformity of the putty applied by the roller 4 to the workpiece 9 to be treated.

[0059] Furthermore, in some embodiments of the present invention, such as Figure 4As shown, the putty scraper 52 is provided with a feeding port 521, which is connected to the cavity 51. This facilitates the feeding of putty into the cavity 51 through the feeding port 521, resulting in a compact and reasonable structural arrangement. The putty scraper 52 ensures the uniformity of the putty on the roller 4 while preventing it from interfering with the feeding operation of the putty box 5.

[0060] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, roller 4 includes a roller body 41 and a flexible felt 42. The roller body 41 is sleeved on the rotating shaft 3, and the flexible felt 42 is adhered to the outer peripheral wall of the roller body 41. The roller body 41 can be made of a rigid material to ensure the overall structural strength of the roller 4. The flexible felt 42 on the outer ring of the roller body 41 can evenly apply putty to the workpiece 9 to be treated, reducing uneven putty coating thickness and thus improving work quality. Furthermore, the flexible felt 42 has a certain frictional force, which helps the roller body 41 better grip the workpiece 9 to be treated, making the putty bond more tightly to the workpiece 9 and enhancing the adhesion of the putty. It can also better fill the tiny holes and gaps in the workpiece 9 to be treated, making the putty coating smoother and reducing coating defects.

[0061] Preferably, the width of the flexible velvet 42 along the axial direction of the rotating shaft 3 is greater than the maximum width of the side edge surface of the workpiece 9 to be treated. This allows the roller 4 to adapt to different widths of the side edge surface of the workpiece 9 to be treated, flexibly adapting to changes in the width of the side edge surface of the workpiece 9 to be treated, thereby ensuring the coating effect of the putty scraping device 100.

[0062] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the drive component 2 includes a servo motor 21 and a coupling. The servo motor 21 is connected to the support assembly 1 and is located on the side of the support assembly 1 opposite to the roller 4 along the axial direction of the rotating shaft 3. The output shaft of the servo motor 21 is connected to the rotating shaft 3 via the coupling. By setting the servo motor 21 and the coupling, driving force can be provided for the rotation of the rotating shaft 3, thereby realizing the automated rotation of the roller 4. The coupling can buffer and reduce the impact and vibration caused by uneven load, inertial reaction force, etc., thus protecting the servo motor 21 and the rotating shaft 3 from damage. This improves the control accuracy and stability of the drive component 2 and extends the service life of the drive component 2 and the rotating shaft 3.

[0063] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 4As shown, the bracket assembly 1 includes a base 11, a bearing bracket 12, and a support base 13. The bearing bracket 12 is connected to the base 11 and is located above the base 11. The support base 13 is connected to the base 11 and is located above the base 11. The bearing bracket 12 and the support base 13 are arranged at intervals along the axial direction of the rotating shaft 3. The rotating shaft 3 is rotatably mounted on the bearing bracket 12 and the support base 13. Along the axial direction of the rotating shaft 3, a roller 4 is located between the bearing bracket 12 and the support base 13. A driving member 2 is located on the support base 13.

[0064] The bearing bracket 12 and the support base 13 can provide two support points for the rotating shaft 3. Along the axial direction of the rotating shaft 3, the roller 4 and the putty box 5 opposite to the roller 4 are located between the bearing bracket 12 and the support base 13. The drive component 2 on the support base 13 is connected to the rotating shaft 3 and drives the rotating shaft 3 to rotate. While ensuring the rotatability of the roller 4, it can also ensure the connection stability between the rotating shaft 3 and the bracket assembly 1. The structure is reasonably arranged, thereby improving the overall structural stability and reliability of the putty scraping device 100.

[0065] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown, the upper end face of the bearing bracket 12 is provided with a receiving groove 121, the upper end of the receiving groove 121 is open, the rotating shaft 3 is disposed in the receiving groove 121, the support base 13 includes a swing base 131, a motor base 132 and a support bearing seat 133, the swing base 131 is connected to the base 11 and is disposed above the base 11, the lower end of the motor base 132 is rotatably connected to the swing base 131, the driving member 2 is connected to the motor base 132, the driving member 2 is disposed on the side of the motor base 132 away from the roller 4 along the axial direction of the rotating shaft 3, the support bearing seat 133 is connected to the motor base 132, the support bearing seat 133 is disposed on the side of the motor base 132 away from the driving member 2, and the rotating shaft 3 passes through the support bearing seat 133.

[0066] Understandably, the support bearing housing 133 is connected to the motor housing 132, allowing the drive component 2 to be connected to the motor housing 132. The rotating shaft 3 is rotatably mounted on the support bearing housing 133. This design ensures the stability of the connection between the drive component 2, the rotating shaft 3, and the support base 13, while also facilitating the connection between the output shaft of the drive component 2 and the rotating shaft 3. The structural design is reasonable. For example, the support bearing housing 133 can be an L-shaped structural component, which can both connect the support bearing housing 133 to the motor housing 132 and avoid space constraints for the connection between the drive component 2 and the rotating shaft 3.

[0067] Furthermore, the swing base 131 is rotatably connected to the base 11, and the lower end of the motor base 132 is rotatably connected to the swing base 131. This allows the entire support bearing housing 133 and motor base 132 to be rotatably connected to the swing base 131. Simultaneously, the end of the rotating shaft 3 facing away from the motor base 132 is located in the upper open receiving groove 121. This allows the axial end of the rotating shaft 3 facing away from the motor base 132 to swing upwards, causing the rotating shaft 3 to rotate around the rotation axis between the motor base 132 and the swing base 131. The roller 4 is then lifted and separated from the cavity 51, facilitating the disassembly of the roller 4 and the rotating shaft 3. This provides convenience for later maintenance, replacement, and cleaning of components such as the roller 4 and the rotating shaft 3, thereby reducing maintenance costs.

[0068] It should be noted that there are many ways to achieve the detachability of the rotating shaft 3 and the roller 4. For example, the rotating shaft 3 and the bracket assembly 1 can be detachably connected by means of direct insertion, magnetic attraction, negative pressure, etc.

[0069] Furthermore, in some embodiments of the present invention, the putty scraping device 100 further includes a support bearing, which is sleeved on the rotating shaft 3 and passes through the support bearing seat 133. By providing the support bearing, the connection stability between the rotating shaft 3 and the support bearing seat 133 is ensured, while the rotatability between the rotating shaft 3 and the support bearing seat 133 is achieved. This also reduces wear and vibration during rotation, thereby improving the service life of the rotating shaft 3 and the support bearing seat 133. Simultaneously, the support bearing also enables the disassembly of the rotating shaft 3 and the support bearing seat 133, facilitating later maintenance and replacement.

[0070] In some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, the putty scraping device 100 also includes a swinging pressure rod 6, which is located above the bearing bracket 12 and is used to confine the rotating shaft 3 between the swinging pressure rod 6 and the bottom wall of the receiving groove 121. The upper end of the receiving groove 121 is open, and the swinging pressure rod 6 can play a limiting role, pressing the rotating shaft 3 between the swinging pressure rod 6 and the bearing bracket 12, thereby ensuring the connection stability between the rotating shaft 3 and the bearing bracket 12, thus ensuring the connection stability between the rotating shaft 3 and the bracket assembly 1, and further ensuring the stability of the roller 4 applying putty to the workpiece 9.

[0071] In some embodiments of the present invention, such as Figure 1 and Figure 4As shown, one end of the swing pressure rod 6 along the first direction is rotatably connected to the bearing bracket 12, and the other end is connected to the bearing bracket 12 via a spring pin 61. The first direction, the axial direction of the rotating shaft 3, and the vertical direction are all perpendicular to each other. Thus, rotating the swing pressure rod 6 allows for the detachment of the rotating shaft 3 from the bearing bracket 12. During normal operation, the end of the swing pressure rod 6 opposite to the rotation axis is fixedly connected to the bearing bracket 12 via a spring pin 113, ensuring that the swing pressure rod 6 confines the rotating shaft 3 within the receiving groove 121, thereby ensuring the stability of the roller 4 applying putty to the workpiece 9.

[0072] When it is necessary to disassemble roller 4 or shaft 3, loosen spring 113 pin so that the end of swing rod 6 away from the axis of rotation can be separated from bearing bracket 12. Then lift swing rod 6 so that it rotates around the axis of shaft 3 between swing rod 6 and bearing bracket 12. Shaft 3 can thus be lifted from above receiving groove 121. The operation is simple and convenient, which can reduce disassembly difficulty and cost.

[0073] Furthermore, in some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown, a ball handle 31 is provided at one end of the rotating shaft 3 away from the drive component 2 in the axial direction, which makes it easy for the operator to hold the ball handle 31 to lift one end of the rotating shaft 3 so that the rotating shaft 3 can rotate, thus reducing the difficulty of rotating the rotating shaft 3.

[0074] Furthermore, in some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown, a handle 62 is provided at the end of the swing lever 6 that is away from the axis of rotation between the swing lever 6 and the bearing bracket 12. This allows the operator to easily lift one end of the swing lever 6 by holding the handle 62 to rotate the swing lever 6, thus reducing the difficulty of rotating the swing lever 6.

[0075] In some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, bearings 63 are respectively provided on the bearing bracket 12 and the swing pressure rod 6. There are multiple bearings 63, which are arranged at intervals along the circumferential direction of the rotating shaft 3. The outer ring of the bearing 63 abuts against the rotating shaft 3. The rotating shaft 3 is confined between the swing pressure rod 6 and the bottom wall of the receiving groove 121. The bearings 63 on the bearing bracket 12 can support the rotating shaft 3, and the bearings 63 on the swing pressure rod 6 can press the rotating shaft 3. Thus, the multiple bearings 63 can achieve positioning and limiting of the rotating shaft 3, thereby enhancing the stability of the rotating shaft 3. At the same time, the bearings 63 can also enhance the rotatability of the rotating shaft 3, reduce wear and vibration when the rotating shaft 3 rotates, thereby improving the service life of the rotating shaft 3, the bearing bracket 12, and the swing pressure rod 6.

[0076] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the base 11 includes a floating base plate 111 and a base plate 112. The bearing bracket 12 and the support base 13 are connected to the floating base plate 111 and disposed above the floating base plate 111. The floating base plate 111 is connected to the base plate 112 and disposed above the base plate 112. The distance between the floating base plate 111 and the base plate 112 in the vertical direction is adjustable. That is, the floating base plate 111 can move up and down relative to the base plate 112, thereby driving the bearing bracket 12, the support base 13, the rotating shaft 3, and the roller 4 to move up and down relative to the base plate 112.

[0077] If the floating substrate 111 is immovable, the operator or automated equipment such as the robot 8 can grab the workpiece 9 to be processed and keep the workpiece 9 in contact with the roller 4. However, the operation and control precision cannot guarantee that the distance between the uneven surface of the workpiece 9 and the roller 4 remains consistent.

[0078] In this application, during the putty application process, the putty application device 100 can adjust the distance between the floating base plate 111 and the base base plate 112 to adapt to the unevenness of the surface of the workpiece 9 to be processed, so that the roller 4 can always keep in contact with the workpiece 9 to be processed, thereby overcoming the situation where the contact is not made due to the movement error of the operator or automated equipment such as the robot 8, thereby improving the coating accuracy and quality of the putty application device 100.

[0079] It should be noted that there are many ways to make the distance between the floating substrate 111 and the base substrate 112 adjustable in the vertical direction. For example, the floating substrate 111 can be moved by means of a cylinder or a force-controlled electric actuator, thereby realizing the vertical movement of the rotating shaft 3 and the roller 4 relative to the base substrate 112.

[0080] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 3As shown, the base 11 also includes springs 113. The two ends of each spring 113 in the vertical direction are connected to the floating substrate 111 and the base substrate 112, respectively. Multiple springs 113 are spaced apart along the circumferential direction of the floating substrate 111. The distance between the floating substrate 111 and the base substrate 112 in the vertical direction can be adjusted using the springs 113, resulting in a simple and easily implemented structure. During the putty application process, the springs 113 automatically adjust their compression under pressure, causing the floating substrate 111 to float up and down to adapt to the unevenness of the workpiece 9 surface, thus ensuring that the roller 4 remains in contact with the workpiece 9, thereby improving the coating accuracy and quality of the putty application device 100. Multiple springs 113 also improve the balance of the floating substrate 111 and reduce the pressure on a single spring 113, ensuring the stability of the floating substrate 111's vertical movement.

[0081] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the base 11 also includes guide posts 114. Each guide post 114 includes a column body 115 and an end cap 116. The upper end of the column body 115 is connected to the end cap 116, and the lower end is connected to the base substrate 112. The column body 115 passes through the floating substrate 111 and the spring 113. Multiple guide posts 114 are arranged in a one-to-one correspondence with multiple springs 113, spaced apart along the circumferential direction of the floating substrate 111. By providing guide posts 114, the floating substrate 111 and the spring 113 can be confined between the end cap 116 and the base substrate 112, thus providing a limiting function. Furthermore, the spring 113 can only extend and retract along the column body 115 of the guide post 114, and the floating substrate 111 can only move up and down along the column body 115, thereby controlling the direction of movement of the spring 113 and the floating substrate 111.

[0082] In some embodiments of the present invention, the support assembly 1 is provided with weight-reducing holes 122 to reduce the weight of the putty scraping device 100, facilitating movement and assembly. For example... Figure 1 As shown in the example, the weight reduction hole 122 is provided on the bearing bracket 12, which can achieve the weight reduction of the putty scraping device 100 without affecting the structural strength of the bearing bracket 12.

[0083] The following describes an adaptive putty applicator 200 for the side edges of irregularly shaped parts according to an embodiment of the present invention.

[0084] The adaptive putty scraping device 200 for the side edge of irregularly shaped parts according to an embodiment of the present invention includes: a worktable 7, the aforementioned putty scraping device 100, and a robot 8.

[0085] Specifically, such as Figures 1-3 and Figure 5As shown, the putty scraping device 100 is mounted on the workbench 7, and the robot 8 is mounted on the workbench 7 to grab the workpiece 9 to be processed and control the workpiece 9 to be processed to contact the roller 4.

[0086] The putty scraping device 100 includes a support assembly 1, a drive component 2, a rotating shaft 3, a roller 4, and a putty box 5. The drive component 2 is mounted on the support assembly 1. The rotating shaft 3 is rotatably mounted on the support assembly 1 and connected to the output shaft of the drive component 2. The roller 4 is rotatably sleeved on the rotating shaft 3. The putty box 5 is mounted on the support assembly 1 and has an open upper cavity 51 for containing putty. The lower part of the roller 4 is located inside the cavity 51. The axial direction and vertical direction of the rotating shaft 3 are perpendicular to each other.

[0087] The drive unit 2 drives the rotating shaft 3 to rotate, thereby causing the roller 4 to rotate. The putty inside the cavity 51 adheres to the lower part of the roller 4 and rotates with the roller 4. At this time, the robot 8 controls the workpiece 9, such as an irregularly shaped structure, to come into contact with the roller 4, so that the surface of the workpiece 9 is pressed against the surface of the roller 4 and rolls relative to it. The putty on the roller 4 is thus applied to the workpiece 9. There is no need for manual handling, moving the workpiece 9, and manually rotating the roller 4, reducing the need for manual operation and thus reducing labor intensity and labor costs. It can also improve control and operation precision, realize automated control and production, and thus effectively improve production efficiency and product quality.

[0088] According to an embodiment of the present invention, the adaptive putty scraping device 200 for the side edge of irregular parts is provided on the support assembly 1 by setting a driving member 2, a putty box 5 and a rotating shaft 3 passing through the roller 4, and the lower part of the roller 4 is located in the cavity 51 at the upper end of the putty box 5. The robot 8 controls the workpiece 9 to be processed to contact the roller 4. The driving member 2 can stably and efficiently drive the roller 4 to rotate. When the roller 4 rotates, it continuously adheres to the putty in the cavity 51 and applies it to the workpiece 9 to be processed that is in contact with the roller 4. There is no need for manual handling and moving of the workpiece 9 to be processed and manual rotation of the roller 4. This can reduce the intensity of manual labor and improve the operation accuracy, thereby improving production efficiency and product quality.

[0089] In some embodiments of the present invention, such as Figure 5 As shown, robot 8 is also used to control the movement direction and speed of the workpiece 9 to be processed. Robot 8 can control the movement trajectory of the workpiece 9 to be processed according to the settings, and at the same time control the movement direction and speed of the workpiece 9 to be processed when it comes into contact with roller 4, thereby realizing the adjustment of the thickness of the putty applied by roller 4 to the workpiece 9 to be processed. Especially when applying putty to the side edge surface of irregularly shaped parts, robot 8 can improve the control precision, thereby improving the uniformity and quality of putty application.
