Description

Technical Field

[0001] This application belongs to the field of production equipment technology, and in particular relates to an oiling mechanism. Background Technology

[0002] Products with internal mechanical structures often require the application of grease to the contact surfaces between moving parts to prevent mechanical wear. However, due to the extremely high viscosity and low fluidity of grease, it cannot be applied directly to the product using a nozzle. Doing so would result in uneven application, causing dry friction between un-greased surfaces and damaging the product. To ensure even application, manual application is typically used. Workers wear gloves and use their fingers to apply grease to the surfaces requiring lubrication. However, for products requiring lubrication in confined spaces, the large size of the fingertips makes manual application inaccurate and can easily contaminate surfaces that don't need lubrication. Summary of the Invention

The motion mechanism can control the oil storage wheel to move to a position opposite to the oil outlet nozzle, so that the oil outlet nozzle applies oil to the oil storage structure. The motion mechanism can also move the oil storage wheel to a position that mates with the product to be oiled, so that after the oil storage structure is connected to the product to be oiled, the motion mechanism can drive the oil storage wheel to rotate to apply oil to the product.

[0005] In some embodiments, the oil storage structure includes a gear portion disposed on the outer periphery of the oil storage wheel, the product to be oiled includes a gear to be oiled, and the motion mechanism can control the oil storage wheel to move to a position opposite to the oil outlet so that the oil outlet applies oil to the gear portion, and the gear portion is used to mesh with the gear to be oiled.

[0006] In some embodiments, the gear portion includes a plurality of teeth, and a guide portion is provided at one end of the teeth in the axial direction of the oil reservoir; the width of the guide portion in the circumferential direction of the oil reservoir gradually decreases in the direction outward from the axial direction of the oil reservoir.

[0007] In some embodiments, the oil storage structure further includes an oil hanging hole, the product to be oiled further includes an oil-to-be-oiled shaft, and the motion mechanism can also control the oil storage wheel to move to a position opposite to the oil outlet, so that the oil outlet applies oil to the wall of the oil hanging hole; the motion mechanism can also move the oil storage wheel to a position where the oil hanging hole mates with the oil-to-be-oiled shaft on the product to be oiled, so that the oil storage wheel applies oil to the oil-to-be-oiled shaft.

[0008] In some embodiments, when the oil reservoir wheel meshes with the gear to be oiled, the oil hanging hole engages with the shaft to be oiled.

[0009] In some embodiments, the oil outlet includes a first oil outlet and a second oil outlet. The motion mechanism can control the oil storage wheel to move to a position opposite to the first oil outlet so that the first oil outlet applies oil to the gear portion. The motion mechanism can also control the oil storage wheel to move to a position opposite to the second oil outlet so that the second oil outlet applies oil to the wall of the oil hanging hole.

[0010] In some embodiments, the oil hanging hole is coaxially arranged with the oil storage wheel, and when the first oil outlet is opposite to the outer peripheral side of the oil storage wheel, the second oil outlet is opposite to the wall of the oil hanging hole.

[0011] In some embodiments, the oiling mechanism further includes an oil storage tank, and the first oil outlet and the second oil outlet are respectively connected to the oil storage tank, the oil storage tank being used to supply oil to the first oil outlet and the second oil outlet.

[0012] In some embodiments, the placement structure is configured as a fixed bottom mold, the fixed bottom mold is provided with a fixing protrusion, the fixing protrusion cooperates with the product to be coated to fix the product to be coated.

[0013] In some embodiments, the motion mechanism includes a two-axis motion mechanism for moving the oil reservoir in the height direction; the two-axis motion mechanism is also used to move the oil reservoir in the arrangement direction of the oiling mechanism and the fixed bottom mold; the oiling mechanism further includes a linear motion mechanism, the fixed bottom mold is mounted on the linear motion mechanism, and the linear motion mechanism is used to move the fixed bottom mold in two directions that are simultaneously perpendicular to the two-axis motion mechanism.

[0014] The oiling mechanism provided in this embodiment first applies grease to the oil storage structure of the oil storage wheel through the oil nozzle.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] This application provides an oiling mechanism to solve the problem that existing products require manual oiling, resulting in poor oiling accuracy. The following description is in conjunction with the accompanying drawings.

[0026] refer to Figure 1 This application provides an oiling mechanism, comprising:

[0027] The oiling mechanism includes an oil outlet.

[0028] A placement structure for holding the product to be coated with oil 70;

[0029] The motion mechanism is equipped with an oil storage wheel 10, which has an oil storage structure. The motion mechanism can control the oil storage wheel 10 to move to a position opposite to the oil outlet so that the oil outlet applies oil to the oil storage structure. The motion mechanism can also move the oil storage wheel 10 to a position that matches the product 70 to be oiled, so that after the oil storage structure is connected to the product 70 to be oiled, the motion mechanism can drive the oil storage wheel 10 to rotate to apply oil to the product 70 to be oiled.

[0030] The oiling mechanism may consist only of an oil outlet, and the lubricating oil can be directly fed into the oil outlet through a pumping mechanism other than the oiling mechanism. The oiling mechanism may also include an oil storage and delivery structure, such as the oil storage tank 30 mentioned below, which is one of the oil storage structures; a pump head may be installed in the oil storage tank 30 to push the lubricating grease in the oil storage tank 30 toward the oil outlet.

[0031] The placement structure can be a simple plane for the stable placement of the product 70 to be coated, facilitating the coating process. Alternatively, the placement structure can be a conveyor belt, allowing the product 70 to be directly transported to a subsequent workstation after being coated, and transporting uncoated products 70 to the coating station provided by the coating mechanism in this embodiment.

[0032] The motion mechanism can be a robotic arm, with an oil storage wheel 10 fixed at the operating end of the robotic arm. The oil storage wheel 10 moves under the drive of the robotic arm and can rotate under the drive of the robotic arm.

[0033] During oiling, the oil reservoir 10 first moves to the oil outlet, where it applies oil to the oil storage structure on the reservoir 10, thus storing a certain amount of grease. After storing oil, the reservoir 10 moves to a position that mates with the product 70 to be oiled, and connects with it (this connection is achieved through the viscosity of the grease; both sides of the grease adhere to the product 70 and the oil storage structure, respectively). Then, the motion mechanism rotates the oiling wheel, causing relative rotation between the oiling wheel and the product 70. During this rotation, the grease is evenly applied to the preset positions on the product 70, achieving automatic oiling. Because the reservoir 10 can be precisely fitted to the product 70, the accuracy of oiling is greatly improved. (Reference) Figure 3 In cases where the area to be oiled in the product 70 is very small and the two parts to be oiled are very close together, manual oiling can easily lead to oil contamination of the parts of the product 70 that do not need oiling. However, using the oil reservoir 10 for oiling avoids this problem because the oil reservoir 10 can be perfectly adapted to the product 70 (e.g., ...). Figure 5 As shown, the oil reservoir 10 can be inserted into the product for oiling, thus improving the accuracy of oiling.

[0034] refer to Figure 2 In some embodiments, the oil storage structure includes a gear portion disposed on the outer periphery of the oil storage wheel 10, and the product to be oiled 70 includes a gear 72 to be oiled. A motion mechanism can control the oil storage wheel 10 to move to a position opposite to the oil outlet nozzle, so that the oil outlet nozzle applies oil to the gear portion, and the gear portion is used to mesh with the gear 72 to be oiled. Figure 2 As shown, when applying oil to the gear, the oil reservoir 10 can be controlled to rotate at least one revolution, so that the gear is coated with oil once. After the oil reservoir 10 meshes with the gear 72 to be oiled, one revolution of the oil reservoir 10 will coat the gear 72 with grease around its circumference. However, when applying oil to the gear, the oil reservoir 10 may not rotate or may rotate less than one revolution. In this case, the number of teeth in the gear and the number of teeth in the gear 72 to be oiled must not be an integer ratio. This allows the oil reservoir 10 to rotate multiple revolutions after the gear 72 to be oiled meshes with the gear, ensuring that the gear 72 is coated with oil around its circumference.

[0035] refer to Figure 2 In some embodiments, the gear portion includes a plurality of teeth 11, and a guide portion 11a is provided at one end of the teeth 11 in the axial direction of the oil reservoir 10; the width of the guide portion 11a in the circumferential direction of the oil reservoir 10 gradually decreases in the direction outward from the axial direction of the oil reservoir 10. Figure 2 As shown, the guide portion 11a is actually a wedge-shaped structure axially positioned towards the oil tanker 10. Figure 5 As shown, in Figure 5 In the illustrated embodiment, when the gear needs to mesh with the gear 72 to be oiled, the oiling gear needs to be... Figure 5 In this process, the oil reservoir 10 moves axially upward and downward to engage with the gear 72 to be oiled. However, the rotation state of the gear 72 to be oiled is random. When the gear part is above the gear 72 to be oiled, the teeth 11 of the gear part need to be aligned with the gap between the teeth of the gear 72 to successfully engage with it. However, at this time, it is very likely that the teeth of the gear 72 to be oiled are aligned with the teeth 11 of the gear part. If the oil reservoir 10 moves axially downward at this time, it may not be able to engage. In this case, the guide part 11a can force the gear 72 to be oiled to rotate, so that the gear part can finally engage smoothly with the gear 72 to be oiled. If the guide part 11a is not provided, a visual inspection device can be provided to determine the rotation state of the gear 72 to be oiled before oiling, and then drive the oil reservoir 10 to rotate to a suitable position through the motion mechanism so that the gear part and the gear 72 to be oiled can engage smoothly. Obviously, the provision of the guide part 11a makes the engagement between the gear to be oiled and the gear part smoother.

[0036] refer to Figure 4 In some embodiments, the oil storage structure further includes an oil hanging hole 12, and the product to be oiled 70 further includes an oil-to-be-oiled shaft 71. The motion mechanism can also control the oil storage wheel 10 to move to a position opposite to the oil outlet, so that the oil outlet applies oil to the wall of the oil hanging hole 12; the motion mechanism can also move the oil storage wheel 10 to a position where the oil hanging hole 12 mates with the oil-to-be-oiled shaft 71 on the product to be oiled, so that the oil storage wheel 10 applies oil to the oil-to-be-oiled shaft 71. Utilizing the viscosity of the grease, the grease can be hung on the inner wall of the oil hanging hole 12. When the oil hanging hole 12 mates with the oil-to-be-oiled shaft 71, the grease hanging on the inner wall of the oil hanging hole 12 naturally adheres to the oil-to-be-oiled shaft 71, completing the oiling process. It is worth noting that, although... Figure 4 In the illustrated embodiment, the oil hanging hole 12 is coaxially arranged with the oil storage wheel 10. However, in some embodiments, the oil hanging hole 12 may not be coaxially arranged with the oil storage wheel 10. For example, the oil hanging hole 12 may extend radially along the oil storage wheel 10 (in this case, the gear portion is not distributed in the circumferential direction of the oil storage wheel 10 to make way for the oil hanging hole 12). When applying oil to the shaft 71 to be oiled, the oil storage wheel 10 may not rotate, but it may also rotate about the axial direction of the oil hanging hole 12. There may be only one oil outlet, so that the oil outlet can be applied to the gear portion and the oil hanging hole 12 in two separate applications. The oil storage wheel 10 can also apply oil to the gear 72 and the shaft 71 to be oiled in two separate applications, especially when the shaft 71 and the gear 72 to be oiled are far apart, applying oil to the gear 72 and the shaft 71 to be oiled in two separate applications is convenient. However, in Figure 1 In the embodiment shown, the gear 72 to be oiled and the shaft 71 to be oiled can be oiled simultaneously, as described below.

[0037] refer to Figure 5In some embodiments, when the oil reservoir 10 meshes with the gear 72 to be oiled, the oil hanging hole 12 engages with the shaft 71 to be oiled. Figure 5 In the illustrated embodiment, the axial directions of the gear 72 to be oiled and the shaft 71 to be oiled are parallel to each other, and the gear 72 to be oiled and the shaft 71 to be oiled are not far apart. The end of the shaft 71 to be oiled and the gear 72 to be oiled are almost on the same plane perpendicular to the axial direction of the shaft 71 to be oiled. At this time, the axial direction of the oil hanging hole 12 can be parallel to the axial direction of the oil storage wheel 10, and the size of the oil storage wheel 10 can be made appropriate so that when the oil hanging hole 12 is engaged with the shaft 71 to be oiled, the gear part meshes with the gear 72 to be oiled. This allows for simultaneous oiling of the gear 72 to be oiled and the shaft 71 to be oiled, improving oiling efficiency. In addition, the oil hanging hole 12 and the oil storage wheel 10 can be coaxially arranged, so that when the oil storage wheel 10 rotates, the oil hanging hole 12 can continuously engage with the shaft 71 to be oiled, achieving uniform oiling of the shaft 71 to be oiled and the gear 72 to be oiled.

[0038] refer to Figure 4 In some embodiments, the oil outlet includes a first oil outlet 21 and a second oil outlet 22. A motion mechanism can control the oil storage wheel 10 to move to a position opposite to the first oil outlet, so that the first oil outlet applies oil to the gear section. The motion mechanism can also control the oil storage wheel 10 to move to a position opposite to the second oil outlet 22, so that the second oil outlet 22 applies oil to the wall of the oil hanging hole 12. Since the gear section and the oil hanging hole 12 may require different amounts of oil, the first oil outlet 21 and the second oil outlet 22 can be respectively set to apply oil to the gear section and the oil hanging hole 12. The oil output can be controlled by controlling the orifice size of the first oil outlet 21 and the second oil outlet 22, so that both the gear section and the oil hanging hole 12 are coated with an appropriate amount of oil. Furthermore, the first oil outlet 21 and the second oil outlet 22 can be optimized for the shapes of the gear and the wall surface, respectively, making it easier for the oil to adhere to the oil storage structure.

[0039] refer to Figure 4 In some embodiments, the oil hanging hole 12 and the oil storage wheel 10 are coaxially arranged, and when the first oil outlet 21 is opposite to the outer peripheral side of the oil storage wheel 10, the second oil outlet 22 is opposite to the wall of the oil hanging hole 12. This allows the gear section and the oil hanging hole 12 to be oiled simultaneously, improving oiling efficiency. In embodiments where the entire circumference of the gear section needs to be oiled, the oil hanging hole 12 and the oil storage wheel 10 can be coaxially arranged, so that when the entire circumference of the gear section is oiled, the entire circumference of the inner wall of the oil hanging hole 12 is also oiled.

[0040] refer to Figure 4In some embodiments, the oiling mechanism further includes an oil storage tank 30, with the first oil outlet 21 and the second oil outlet 22 respectively connected to the oil storage tank 30. The oil storage tank 30 is used to supply oil to the first oil outlet 21 and the second oil outlet 22. The first oil outlet 21 and the second oil outlet 22 share the oil storage tank 30, which can reduce the production cost of the oiling mechanism.

[0041] refer to Figure 3 In some embodiments, the placement structure is configured as a fixed bottom mold, on which a fixing protrusion 41 is provided. The fixing protrusion 41 cooperates with the product 70 to be oiled to fix the product 70 to be oiled. Since the viscosity of the grease is very high, when the oil reservoir 10 and the product 70 to be oiled rotate relative to each other, the product 70 to be oiled may rotate as a whole, interfering with the oiling process. Therefore, after the fixed bottom mold 40 fixes the product 70 to be oiled through the fixing protrusion 41, it can improve the fixing effect of the product 70 to be oiled, prevent the product 70 to be oiled from rotating, and make the oiling more accurate.

[0042] refer to Figure 1 In some embodiments, the motion mechanism includes a two-axis motion mechanism 50, which is used to move the oil storage wheel 10 in the height direction; the two-axis motion mechanism 50 is also used to move the oil storage wheel 10 in the arrangement direction of the upward oiling mechanism and the fixed bottom mold. The two-axis motion mechanism 50 moves via a track, which is highly stable and low in cost.

[0043] refer to Figure 1 In some embodiments, the oiling mechanism further includes a linear motion mechanism 60, with a fixed bottom mold 40 mounted on the linear motion mechanism 60. The linear motion mechanism 60 is used to move the fixed bottom mold in two directions that are simultaneously perpendicular to the two-axis motion mechanism 50. This, together with the two-axis motion mechanism 50, constitutes a three-axis motion mechanism, making the positional relationship between the oil storage wheel 10 and the product 70 to be oiled more flexible and facilitating oiling.
