Description

Technical Field

[0001] This utility model relates to plasma cleaning equipment technology, and in particular to a drum positioning device for a drum plasma cleaning equipment. Background Technology

[0002] In plasma equipment, plasma cleaning of product surfaces to improve surface activity is a relatively advanced surface treatment technology for electronic product casings. Among the various products requiring surface cleaning and improved surface activity, many are small, numerous devices. Ideally, these products can be cleaned by mixing with plasma gas through a tumbling process. However, currently, plasma cleaning equipment with rollers is not common. In some roller-type cleaning equipment, there is only a fixed roller cleaning position. The need for multi-angle roller rotation is for loading control during product placement, cleaning, and unloading, aiming for better cleaning. However, in roller plasma equipment with multi-angle control, the existing angle positioning structure is quite complex, generally achieved through multiple toothed grids and pins. This is insufficient for equipment with high rotation frequency and cannot guarantee a long service life, and is prone to jamming and malfunctions during operation. Summary of the Invention

The vertical part of the plate has a number of detection holes at a specified position that are the same as the number of positioning heads. A detection sensor is installed on each detection hole. Each detection sensor is positioned facing the side of the positioning head. The positioning point plate rotates with the fixed shaft by a set angle range. Within this angle range, each positioning head will only coincide with the center of the corresponding detection sensor once.

[0008] As described above, in the drum positioning device for a drum plasma equipment, the other side of the fixed shaft base is fixed on an arc-shaped connecting seat, the inner side of the arc-shaped connecting seat is an arc surface that fits against the outer surface of the vacuum chamber, and the arc-shaped connecting seat is fixed on the outer surface of the vacuum chamber; the fixed bearing assembly includes an Ω-shaped bearing sleeve, a rotating bearing is provided inside the bearing sleeve, and the fixed shaft is inserted into and fixed inside the rotating bearing.

[0013] 8: Frame, 9: Vacuum chamber, 27: Fixed shaft, 31: Fixed shaft base, 32: Arc-shaped connecting seat, 33: Positioning plate, 34: Bearing seat sleeve, 35: Connecting seat plate, 36: Detection plate, 37: Positioning head, 38: Detection sensor. Detailed Implementation

[0014] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0015] This utility model discloses a drum positioning device for a drum plasma equipment. In a preferred embodiment, please refer to... Figure 1 As shown, preferably, this utility model is a drum rotation connection mechanism installed on a drum plasma device. The vacuum chamber 9 of the drum device has fixed shafts 27 on both sides of its fixed portion, which are hung on its frame 8. The drum rotation connection mechanism is located on the fixed portions on both sides. The vacuum chamber 9 can swing at an elevation angle around the fixed shafts 27 of the fixed portion, providing different operating modes for plasma cleaning and improving the plasma cleaning effect.

[0016] The roller rotation connection mechanism includes a fixed shaft base 31 and a fixed bearing assembly. The fixed shaft 27 is fixedly fixed to the outward side of the fixed shaft base 31. A connecting seat plate 35 is provided between the bottom of the detection point plate 36 and the top of the frame 8. The roller rotation connection mechanism includes a positioning device, which includes a positioning point plate disposed on the fixed shaft base 31 and a detection point plate 36 disposed on the connecting seat plate 35. At least three positioning pins are provided on the positioning point plate at a specified distance away from the fixed shaft 27 and at different angles around the fixed shaft 27. The positioning pin hole has a positioning head 37 protruding outward and fixed thereon; the detection point plate 36 is an L-shaped plate that is fixed on the connecting base plate 35 and bent upward. The vertical part of the plate has the same number of detection holes as the positioning heads 37 at a designated position. Detection sensors 38 are installed on the detection holes respectively. Each detection sensor 38 is set on one side facing the positioning head 37. The positioning point plate rotates within a set angle range as the fixed shaft 27 rotates. Within this angle range, each positioning head 37 will only coincide with the center of the corresponding detection sensor 38 once.

[0017] The roller rotation connection mechanism is equipped with a positioning device, which includes a positioning point plate 33 disposed on the fixed shaft base 31 and a detection point plate 36 disposed on the connecting seat plate 35. The positioning point plate 33 is provided with at least three positioning pin holes at a specified distance away from the fixed shaft 27 and at different angles around the fixed shaft 27. A positioning head 37 is fixedly fixed to the positioning pin hole by protruding outward. The detection point plate 36 is an L-shaped plate that is bent upward on the connecting seat plate 35. The vertical part of the plate has the same number of detection holes as the positioning heads 37 at a specified position. A detection sensor 38 is installed on each detection hole. Each detection sensor 38 is positioned facing the side of the positioning head 37. The positioning point plate 33 rotates within a set angle range as the fixed shaft 27 rotates. Within this angle range, each positioning head 37 will only coincide with the center of the corresponding detection sensor 38 once. Preferably, the size of the positioning head 37 corresponds exactly to the probe of the detection sensor 38. When the vacuum chamber 9 swings up and down and rotates, the positioning plate 33 also rotates around the fixed axis. The movement trajectory of the positioning head 37 is an arc curve. Only one detection sensor 38 is set to appear on the arc curve trajectory of one positioning head. Of course, the radial distance between each positioning head 37 and the axis of the fixed axis 27 can be set to be different. In this case, within the range of rotation of the vacuum chamber 9, a positioning point is configured for each positioning head 37 and detection sensor 38. Then, the positioning point of each positioning head and detection sensor can be used as a positioning point to provide a positioning signal for locking the rotation of the roller 29. For example, the positioning signal of the positioning point can be used to control the action of the lifting mechanism 13, so that the vacuum chamber 9 can obtain three rotational positioning states: tilting upward, horizontal, and tilting downward. Furthermore, the positioning pin hole can be an elongated arc-shaped hole, which facilitates the adjustment of the fixed position of the positioning head 37, thereby adjusting more different positioning positions within the pitch range of the vacuum cavity 9 and providing more operational variations.

[0018] In a preferred embodiment of the roller positioning device for a roller plasma equipment as described above, the roller fixing part is provided with a roller rotation connecting mechanism. The roller rotation connecting mechanism is provided with a fixed shaft base 31 and a fixed bearing assembly. The fixed shaft base 31 protrudes outward and fixes the fixed shaft 27. The other side of the fixed shaft base 31 is fixed on an arc-shaped connecting seat 32. The inner side of the arc-shaped connecting seat 32 is an arc surface that fits against the outer surface of the vacuum chamber 9. The arc-shaped connecting seat 32 is fixed to the outer surface of the vacuum chamber 9. Preferably, it is installed at the middle position in the vertical direction on the side of the vacuum chamber 9 so that the vacuum chamber 9 can maintain horizontal balance. The fixed bearing assembly includes an Ω-shaped bearing sleeve 34. A rotating bearing is provided inside the bearing sleeve 34. The fixed shaft 27 is inserted into the rotating bearing and fixed. A connecting plate 35 is provided between the bottom of the bearing sleeve 34 and the top of the frame 8. Preferably, the protrusions on both sides of the bearing housing 34 are fixed to the frame 8 by bolts, so that the vacuum chamber can be stably hung on the frame 8 by fixing the bearing housing.

[0019] This utility model discloses a drum positioning device for drum plasma equipment. It can be used to support the drum of a drum plasma equipment. By detecting multiple positioning points separately, the model of different positioning points can be obtained, and the external lifting mechanism can be controlled to position the drum separately, so that the drum can have multiple angle changes and movements, providing a better cleaning space and cleaning mode for plasma cleaning.

[0020] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
