Description

Technical Field

[0001] This utility model relates to a laser cleaning and rotating mechanism, and more particularly to a laser cleaning and rotating mechanism suitable for automotive water-cooled plates. Background Technology

[0002] In the automotive water-cooled plate industry, water-cooled plates are typically longer than 1 meter. When all four sides of the product need to be laser-cleaned, the laser head is usually kept stationary to ensure the stability of the laser cleaning process. However, this requires the product to rotate in tandem. Since the product is so long, fixing only one end makes the structure very weak, and the other end is easily deformed and sags due to gravity. Moreover, synchronous rotation places high demands on parameters such as motor response, and even a slight error can lead to asynchrony, causing damage to the product and the mechanism. Therefore, it is necessary to design a mechanism that can fix both ends of the product and rotate synchronously.

[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of laser cleaning and rotating mechanism with greater industrial application value. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a laser cleaning and rotation mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The laser cleaning and rotation mechanism includes a left laser cleaning and rotation assembly and a right laser cleaning and rotation assembly with the same structure, and the left laser cleaning and rotation assembly and the right laser cleaning and rotation assembly are symmetrically arranged.

[0007] The left laser cleaning and rotation assembly includes a Y-axis linear guide rail, on which a movable fixed frame driven by a Y-axis adjustment module is connected. A Z-axis module is connected to the movable fixed frame, and a Z-axis sliding plate is connected to the Z-axis module. A laser cleaning bracket is connected between the Z-axis sliding plates, and a pulsed fiber laser is connected to the laser cleaning bracket. A rotating fixed plate is connected to the movable fixed frame located below the laser cleaning bracket. A servo motor is connected to the lower back of the rotating fixed plate via a motor bracket. A drive wheel is connected to the drive shaft of the servo motor. A bearing seat is connected to the upper end of the rotating fixed plate, and a rotating shaft passes through the bearing seat. One end of the rotating shaft is connected to a synchronous wheel on the same side as the drive wheel. The synchronous wheel and the drive wheel are synchronously connected via a synchronous belt. The other end of the rotating shaft is connected to a gripper cylinder, and a clamping block for clamping the product is connected to the gripper cylinder. The gripper cylinder and the pulsed fiber laser are vertically opposite each other and are arranged on the same axis.

[0008] Preferably, in the laser cleaning and rotating mechanism, a height adjustment platform for manually adjusting the height is connected between the laser cleaning bracket and the pulsed fiber laser.

[0009] Preferably, in a laser cleaning and rotating mechanism, a vacuum cleaner for collecting waste generated by the laser on the product is connected to the laser cleaning bracket.

[0010] In a preferred embodiment of the laser cleaning and rotating mechanism, two spaced and opposite pulsed fiber lasers are connected to the laser cleaning bracket, and two gripper cylinders are connected to the rotating fixed plate via bearing seats and rotating shafts, with the gripper cylinders corresponding one-to-one with the pulsed fiber lasers.

[0011] Preferably, in the laser cleaning and rotating mechanism, the laser cleaning bracket is connected to an adjusting tension wheel for adjusting the tension of the timing belt.

[0012] In a preferred embodiment of the laser cleaning and rotation mechanism, three tensioning wheels are provided, arranged in a triangular pattern.

[0013] In a preferred embodiment of the laser cleaning and rotation mechanism, the tensioning wheel includes a tensioning shaft, a tensioning groove is provided on the laser cleaning bracket, the tensioning shaft passes through the tensioning groove, a tensioning wheel is connected to one end of the tensioning shaft on the same side as the synchronous wheel, and a fixing nut is connected to the other end of the tensioning shaft.

[0014] By means of the above solution, this utility model has at least the following advantages:

[0015] This invention achieves product rotation through the rotation of a synchronous pulley and a synchronous belt. The synchronous pulley and a gripper cylinder form a clamping mechanism. During operation, the gripper cylinder clamps the product using the POM workpiece and simultaneously blocks the water nozzle to prevent dust from entering during laser cleaning. Because this mechanism fixes both ends of the product, it overcomes the drawback of fixing only one end. Furthermore, the use of a synchronous belt makes it easier to achieve synchronized operation. The Y-axis adjustment module enables compatibility with products of different lengths, effectively improving cleaning efficiency.

[0023] Example

[0024] like Figure 1 , Figure 2 and Figure 3As shown, a laser cleaning and rotation mechanism includes a left laser cleaning and rotation assembly 100 and a right laser cleaning and rotation assembly 200 with identical structures, symmetrically arranged. The left laser cleaning and rotation assembly 100 includes a Y-axis linear guide rail 6, on which a movable fixed frame 14 driven by a Y-axis adjustment module 8 is connected. A Z-axis module 1 is connected to the movable fixed frame 14, and a Z-axis sliding plate is connected to the Z-axis module 1. A laser cleaning bracket 11 is connected between the Z-axis sliding plates, and a pulsed fiber laser 2 is connected to the laser cleaning bracket 11. A rotating fixed plate 13 is connected to the movable fixed frame 14 below the frame 11. A servo motor 7 is connected to the lower back of the rotating fixed plate 13 via a motor bracket. A drive wheel 5 is connected to the drive shaft of the servo motor 7. A bearing seat 16 is connected to the upper end of the rotating fixed plate 13. A rotating shaft is threaded through the bearing seat 16. One end of the rotating shaft is connected to a synchronous wheel 17 on the same side as the drive wheel. The synchronous wheel 17 and the drive wheel 5 are synchronously connected via a synchronous belt 3. The other end of the rotating shaft is connected to a gripper cylinder 18. A clamping block 15 for clamping the product is connected to the gripper cylinder 18. The gripper cylinder 18 and the pulsed fiber laser 2 are vertically opposite each other and are arranged on the same axis.

[0025] In this embodiment, a height adjustment platform 12 for manually adjusting the height is connected between the laser cleaning bracket 11 and the pulsed fiber laser 2, and the height can be adjusted as needed.

[0026] In this embodiment, the laser cleaning bracket 11 is connected to a vacuum cleaner 10 for collecting the waste generated by the laser on the product. Multiple vacuum cleaners are provided to achieve comprehensive coverage and collect the waste generated by the laser in a timely manner to prevent product contamination.

[0027] In this embodiment, two spaced and opposite pulsed fiber lasers 2 are connected to the laser cleaning bracket 11. Two gripper cylinders are connected to the rotating fixing plate 13 via bearing seats and a rotating shaft. Each gripper cylinder corresponds one-to-one with a pulsed fiber laser 2. Furthermore, an adjusting tension wheel 4 for adjusting the tension of the synchronous belt is connected to the laser cleaning bracket 11. This allows both products 9 to work simultaneously, effectively improving work efficiency.

[0028] The adjustable tensioning rollers 4 are provided in three parts, arranged in a triangular pattern. Each adjustable tensioning roller 4 includes a tensioning shaft. A tensioning groove is provided on the laser cleaning bracket 11, and the tensioning shaft passes through the tensioning groove. A tensioning roller is connected to one end of the tensioning shaft, which is on the same side as the synchronous pulley, and a fixing nut is connected to the other end of the tensioning shaft.

[0029] The Y-axis adjustment module and Z-axis module of this utility model are existing moving modules known to those skilled in the art, and will not be described in detail here.

[0030] The working principle of this utility model is as follows:

[0031] In practice, product 9 is transported from the previous station to this station. The Y-axis adjustment module 8 moves to a position where the gripper cylinder 18 can clamp the water nozzle. The gripper cylinder clamps the product, and the transport mechanism from the previous station moves away. The left and right Z-axis modules drive the pulsed fiber laser 2 to descend to a suitable height for laser cleaning (the product has a front, a back, and two rounded corners). After the front is cleaned, the servo motor 7 rotates, driving the synchronous belt 3 and synchronous pulley 17 to rotate. After rotating 180°, the product is on the back, and the pulsed fiber laser 2 cleans the back. The servo motor 7 rotates, driving the synchronous belt 3 and synchronous pulley 17 to rotate. After rotating 90°, the product is on the rounded corner, and the pulsed fiber laser cleans the rounded corner. The cleaning of the other rounded corner is repeated. After cleaning, the product is removed from the previous station via the transport mechanism, ready for the next batch of products.

[0032] The product rotation is achieved through the rotation of a synchronous pulley and a synchronous belt. The synchronous pulley and the gripper cylinder form a clamping mechanism. During operation, the gripper cylinder clamps the product using the POM workpiece and simultaneously blocks the water nozzle to prevent dust from entering during laser cleaning. Because this mechanism fixes both ends of the product, it overcomes the limitation of fixing only one end. Furthermore, the use of a synchronous belt makes it easier to achieve synchronized operation. The Y-axis adjustment module allows for compatibility with products of different lengths, effectively improving cleaning efficiency.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. 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 application based on the specific circumstances.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
