Description

[0001] The utility model relates to the technical field of grinding machines, in particular to a positioning mechanism of a planetary gear set, an automatic material taking and placing mechanism and a glass grinding machine. Background Art

[0002] In the current glass grinding machines, the main machine uses a variable frequency speed regulating motor to drive the sun wheel to rotate in the forward and reverse directions. The planetary wheels revolve and rotate between the sun wheel and the inner ring gear at the same time. The workpiece revolves and rotates in the carrier. It is also equipped with a pressurized cylinder to grind the material on the planetary wheel through a plane pressurization form. The grinding pressure is adjustable, which is easy for precision grinding.

[0003] Due to the lack of a planetary bracket, the rotation direction of the planetary wheel can be changed. Coupled with factors such as gear processing deviation, it is difficult to determine parameters such as the relative position and rotation angle of the planetary wheel, forcing manual loading and unloading. This hinders the glass grinder from realizing automated loading and unloading processes. The traditional manual loading and unloading method is inefficient and prone to errors. It is difficult to meet the needs of high-precision, large-scale production and there are also extremely high risks to personnel safety. Summary of the invention

[0029] like Figures 1 to 3 As shown, the first aspect of the embodiment of the present application provides a positioning mechanism of a planetary gear set, the planetary gear set 1 includes a sun gear 11, a planetary gear 12 and an inner ring gear 13; the inner ring gear 13 is arranged coaxially with the sun gear 11, the planetary gear 12 is arranged between the sun gear 11 and the inner ring gear 13, the planetary gear 12 is meshed with the sun gear 11 and the inner ring gear 13, the sun gear 11 is driven to rotate by a motor, and then the planetary gear 12 is driven to revolve around the sun gear 11 and rotate on its own axis.

[0030] The first detection point 121 and the second detection point 122 are arranged on the same plane of the planetary wheel 12. The first detection point 121 is arranged at the axis position of the surface of the planetary wheel 12, and the second detection point 122 is arranged at another different position on the surface of the planetary wheel 12. The axis position and the angular coordinate parameters of the planetary wheel can be determined by the two detection points on the same plane of the planetary wheel. Since the orbit of the planetary wheel 12 revolving around the sun wheel 11 is fixed and unique, that is, the running track of the axis of the planetary wheel 12 and the first detection point 121 are on a fixed orbit; and during the rotation of the planetary wheel 12, the second detection point 122 revolves around the axis of the planetary wheel 12 and the first detection point 121.

[0031] The positioning mechanism also includes a detection unit 2 and a control unit 3; the detection unit 2 includes a first sensor 21 and a second sensor 22, the first sensor 21 is aligned with the orbital track of the axis of the planetary gear 12, when the planetary gear 12 rotates until its axis (i.e., the first detection point 121) is aligned with the first sensor 21, the first sensor 21 can detect the position of the first detection point 121.

[0032] In addition, the second sensor 22 can also rotate around the first sensor 21, and the distance from the second sensor 22 to the first sensor 21 is equal to the distance from the second detection point 122 to the first detection point 121. That is, when the axis of the planetary gear 12 is aligned with the first sensor 21 and the planetary gear 12 stops moving, the running track of the second sensor 22 coincides with the track of the second detection point 122 revolving around the first detection point 121.

[0033] The control unit 3 is electrically connected to the planetary gear set 1 and the detection unit 2, and the specific control principle is as follows: at startup, the planetary gear set 1 runs, the sun gear 11 drives the planetary gear 12 to revolve, and the detection unit 2 performs real-time detection; when the first sensor 21 detects the first detection point 121, the control unit 3 controls the planetary gear set 1 to stop running on the one hand, and controls the second sensor 22 to revolve around the first sensor 21 on the other hand, until the second sensor 22 detects the second detection point 122. At this time, the position coordinates of the first detection point 121 and the second detection point 122 are obtained, so that the axial position and angular coordinate parameters of the planetary gear 12 can be obtained, and the position information of a single planetary gear 12 can be determined.

[0034] The positioning mechanism of the planetary gear set provided in this embodiment realizes the precise positioning and automatic control of the planetary gears, so as to facilitate further application in automatic material loading and unloading mechanisms and glass grinders, thereby improving the level of automation and production efficiency, saving labor costs, and reducing personnel safety hazards.

[0035] During the specific implementation of this embodiment, the detection unit 2 also includes a base 23, a motor 24 and a connecting rod 25; the motor 24 and the first sensor 21 are installed on the base 23; the second sensor 22 is installed at one end of the connecting rod 25, and the other end of the connecting rod 25 is connected to the output end of the motor 24 to drive the second sensor 22 to rotate around the first sensor 21.

[0036] In the specific implementation process of this embodiment, the positioning mechanism also includes a moving unit 4, which is used to move the detection unit 2. When positioning detection is required, the detection unit 2 is moved above the planetary gear set 1, and the first sensor 21 is aligned with the orbit where the axis of the planetary gear 12 is located; after the positioning is completed, the detection unit 2 is moved outside the planetary gear set 1, so that the grinder can run above the planetary gear set 1 without blocking the space.

[0037] In the specific implementation process of this embodiment, see Figure 4 The moving unit 4 includes a driving device 41, a sliding member 42 and a guiding member 43; the detecting unit 2 is installed at the end of the sliding member 42, the sliding member 42 is slidably connected with the guiding member 43, and the driving device 41 drives the sliding member 42 to slide, so that the detecting unit 2 enters or leaves the space above the planetary gear set 1.

[0038] In the specific implementation of this embodiment, there are multiple planetary gears 12. After determining the position information of a single planetary gear 12, the control unit 3 controls the planetary gear set 1 to continue to operate to position the next planetary gear 12. The principle is as above and will not be repeated here.

[0039] Based on the same inventive concept as the positioning mechanism of the above-mentioned planetary gear set, the second aspect of the embodiment of the present application also provides an automatic material loading and unloading mechanism, which includes the above-mentioned positioning mechanism and can achieve the same technical effect as it. The parts and beneficial effects of the same embodiment as the above-mentioned automatic material loading and unloading mechanism are not described in detail here. The automatic material loading and unloading mechanism also includes a loading and unloading unit 5 for loading and unloading materials. The planetary wheel 12 is provided with a loading position 123, and the number of the loading position 123 is multiple to improve processing efficiency and flexibility; the loading and unloading unit 5 is electrically connected to the control unit 3. Specifically, the position parameters of each loading position 123 on the planetary wheel 12 are pre-set. After determining the position information of the planetary wheel 12, the position information of each loading position 123 can be obtained according to the preset position parameters; the control unit 3 sends the position information and execution instructions to the loading and unloading unit 5 to control the loading and unloading unit 5 to put the material into the loading position 123 for grinding or take the ground material out of the loading position 123 to achieve automatic loading and unloading.

[0040] Furthermore, the loading and unloading unit 5 is configured as a robotic arm with multiple degrees of freedom, and a suction cup assembly is provided at the end of the robotic arm to ensure accurate grasping and placement of materials of various shapes and sizes.

[0041] Furthermore, the automatic material loading and unloading mechanism also includes a material preparation unit 6, which is used to place materials, so that the loading and unloading unit 5 can grab materials from the material preparation unit 6 or take the ground materials out from the loading position 123 and put them into the material preparation unit 6, thereby realizing automatic supply and management of materials and improving production efficiency.

[0042] Based on the same inventive concept as the above-mentioned automatic material loading and unloading mechanism, the third aspect of the embodiment of the present application also provides a glass grinding machine, including the above-mentioned automatic material loading and unloading mechanism, and can achieve the same technical effect. The parts and beneficial effects of this embodiment that are the same as the above-mentioned automatic material loading and unloading mechanism embodiment will not be described in detail here.

[0043] It can be seen from the above embodiments that the positioning mechanism of the planetary gear set of the utility model and its application in the automatic material taking and placing mechanism and the glass grinding machine significantly improve the positioning accuracy and automation level, and have high practical value and promotion potential.
