Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, specifically to an inductive vision positioning paint stripping device. Background Technology

[0002] The principle of laser paint stripping is that when a laser beam irradiates the surface of an object coated with paint, the pigments, resins, and other components in the paint layer absorb the energy of the laser. Due to the high energy density of the laser, the paint layer rapidly heats up after absorbing energy, reaching the melting and boiling points of the paint, thus melting and vaporizing it, and the paint in the corresponding location is removed.

[0003] In the laser paint stripping process, the positioning of the parts directly affects the accuracy of the subsequent laser paint stripping. At present, visual positioning is mostly used, that is, the position of the parts is first determined by taking pictures with a vision camera, and then the system recognizes the pictures. In order to facilitate assembly line operation, the parts are usually loaded onto a turntable or conveyor belt and moved to the lower part of the laser, and then the paint stripping operation is performed accordingly.

[0004] The above process has the following problems when applied to the field of inductor stripping: Since the inductor is generally small in size, if the inductor rotates along with the turntable or the timing belt moves forward, the relative displacement between the inductor and the timing belt or turntable can easily occur. This displacement will cause the laser to shift its position for stripping the inductor, affecting the stripping effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an inductive visual positioning paint stripping device.

[0006] The specific technical solution is as follows: an inductive visual positioning paint stripping device, comprising a machine base, a lead screw slide, a camera mounting bracket, a camera, a laser mounting bracket, a laser, and a tray frame. The lead screw slide is disposed on the machine base. The camera mounting bracket and the laser mounting bracket are connected to the slider of the lead screw slide. The camera is mounted on the camera mounting bracket, and the laser is mounted on the laser mounting bracket. The tray frame is disposed on the machine base, and a tray is placed on the tray frame. Inductors that need to be stripped are arranged in the tray. The movement of the lead screw slide can move the camera and the laser to the top of the tray respectively.

[0007] Furthermore, the machine is also provided with a smoking channel, one end of which is an open trumpet shape and is correspondingly located on the side of the tray frame, and the other end extends to the outside of the machine.

[0008] Furthermore, the machine platform is also equipped with a light source, which is a ring light source and is located on the upper part of the tray frame.

[0009] Furthermore, the machine platform also has a camera baffle. When the laser is located on the upper part of the tray frame, the camera baffle is located below the camera lens and is used to block the camera lens.

[0010] Furthermore, the laser mounting bracket includes a vertical frame and a laser mounting plate. The vertical frame is vertically arranged, and its bottom is connected to the slider of the lead screw slide. The laser mounting plate is horizontally arranged and has bolt holes for connecting the laser. The bottom of the laser has a straight groove, and the laser is connected to the laser mounting plate by bolts. The bolts are connected in the straight groove of the laser and can slide within the straight groove. The vertical frame and the laser mounting plate are connected by an adjustment mechanism for adjusting the height of the laser mounting plate.

[0011] Furthermore, the camera mounting bracket includes a column, a base plate, an adjustment mechanism, and a camera mounting seat. The column is vertically mounted on the slider of the lead screw slide table, the base plate is mounted on the column and is horizontally arranged, there are two adjustment mechanisms connected to each other, and the camera mounting seat is connected to one of the adjustment mechanisms. The two adjustment mechanisms are used to adjust the vertical height and front-back position of the camera mounting seat, respectively.

[0012] Furthermore, the pallet rack includes a base, side plates, and an adjustment mechanism. The base is horizontally positioned for placing the pallet. The side plates are located on both sides of the base to align the position of the pallet placed on the base. The bottom of the base is connected to the machine platform via the adjustment mechanism, which is vertically positioned for adjusting the height of the base.

[0013] Furthermore, the adjustment mechanism includes a fixed block, a movable block, and a limiting mechanism. The fixed block and the movable block are connected by a set of cross roller guides, allowing the fixed block and the movable block to slide along the direction of the cross roller guides. The limiting mechanism is used to adjust the relative position of the fixed block and the movable block and to complete the fixing.

[0014] Furthermore, the limiting mechanism includes an adjusting block, a connecting shaft, and a locking bolt. The adjusting block and the connecting shaft are fixedly connected to the fixed block and the movable block, respectively. The adjusting block has a slotted circular hole, and the connecting shaft passes through the circular hole on the adjusting block. A locking bolt is provided at the slotted position of the circular hole on the adjusting block. When the locking bolt is tightened, the adjusting block and the connecting shaft are relatively fixed, and at this time, the fixed block and the movable block are relatively fixed. When the locking bolt is loosened, the adjusting block can slide relative to the connecting shaft, and at this time, the fixed block and the movable block can slide relative to each other.

[0015] Furthermore, the limiting mechanism includes a first connecting block, a second connecting block, and an adjusting bolt. The first connecting block and the second connecting block are fixedly connected to the fixed block and the movable block, respectively. The first connecting block is provided with a bolt hole, and the adjusting wheel is bolted into the bolt hole. One end of the adjusting bolt is connected to the second connecting block, and the adjusting bolt can rotate freely. By rotating the adjusting bolt, the relative position of the first connecting block and the second connecting block is adjusted.

[0016] Compared with the prior art, the technical solution proposed in this utility model sets up a positioning camera and laser that can move synchronously back and forth, while the inductor is placed inside the tray, and the tray is placed on the tray frame. The inductor does not move during the entire process. The camera and laser are driven to move to the upper part of the tray in sequence through the lead screw slide, so as to perform positioning and painting respectively. This will not cause relative displacement and has higher accuracy. At the same time, the camera and laser are connected to corresponding adjustment mechanisms to facilitate the adjustment of the position of the camera and laser, which further ensures the working accuracy.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0024] To address the problems existing in the relevant prior art, this utility model proposes an inductive visual positioning paint stripping device. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1 An inductor vision positioning paint stripping device includes a machine base 1, a lead screw slide 2, a camera mounting bracket 3, a camera 4, a laser mounting bracket 5, a laser 6, and a tray frame 7. The lead screw slide 2 is mounted on the machine base 1. The lead screw slide 2 is a standard module available on the market and is equipped with a dedicated motor. Currently, the repeatability of this type of lead screw slide can be ±0.01mm. Those skilled in the art can choose according to their needs. The camera mounting bracket 3 and the laser mounting bracket 5 are connected to the slider of the lead screw slide 2. The camera 4 is mounted on the camera mounting bracket 3, and the laser 6 is mounted on the laser mounting bracket 5. The tray frame 7 is located on the machine base 1 and holds a tray 8. The inductors to be stripped are arranged in the tray 8. The movement of the lead screw slide 2 can move the camera 4 and the laser 6 to the top of the tray, respectively. The camera is used to photograph and position the inductors on the tray, and the laser is used to perform paint stripping operations on the corresponding pin positions of the inductors.

[0026] In the above scheme, camera 4 and laser 6 are connected to the system. The general working principle is as follows: first, the camera takes a picture of the part that needs to be peeled off. The system identifies the position of the part in the picture taken by the camera and determines the position where the paint needs to be peeled off. Then, the system controls the laser to perform the paint peeling operation at the designated position. The above principle has been widely used in visual positioning paint peeling. This is a simple application of the existing technology and will not be specifically limited here.

[0027] In the above scheme, the specific working process is as follows: the operator first places the inductor in the tray, then the slider of the lead screw slide 2 moves to move the camera 4 directly above the tray and takes a picture of the inductor in the tray. Then the system recognizes the picture and determines the position where the paint needs to be stripped. Then the slider of the lead screw slide moves to move the laser 6 above the tray. The laser performs paint stripping on the surface of the inductor. The tray does not move at all during the whole process. At the same time, the displacement accuracy of the camera and the laser is driven by the lead screw slide, and the accuracy of the lead screw slide can be controlled within ±0.01mm, thus ensuring the paint stripping accuracy.

[0028] Please continue reading. Figure 1 The machine 1 is also equipped with a smoke extraction channel 9. One end of the smoke extraction channel 9 is open and funnel-shaped and is correspondingly set on the side of the tray frame. The other end extends to the outside of the machine. In actual use, a negative pressure fan is connected to the end that extends to the outside of the machine. When the laser is working, the pigments, resins and other components in the paint layer on the inductor surface will vaporize or sublimate, and the generated smoke can be discharged to the outside of the machine through the smoke extraction channel.

[0029] Please continue reading. Figure 1 The machine 1 is also equipped with a light source 10, which is a ring light source located on the upper part of the tray frame. When the tray is placed on the tray frame, the ring light source surrounds the tray, providing sufficient illumination for the camera 4 to take pictures. This ensures the quality of the pictures and prevents shadows from appearing, thus making the system more accurate when recognizing photos.

[0030] Please continue reading. Figure 1 The machine base 1 also has a camera baffle 11. When the laser 6 is located on the upper part of the tray frame 7, the camera baffle 11 is located below the lens of the camera 4 and is used to block the lens of the camera 4. The laser emitted by the laser has high energy. If it is reflected by the parts and enters the camera lens, it will damage the camera head. In this way, when the laser is working, the camera baffle blocks the lens of the camera, which can effectively avoid the above situation. Specifically, the camera baffle can be fixedly connected to the machine base 1 by the optical axis 12.

[0031] Please see Figure 1 and Figure 2 The laser mounting bracket 5 includes a vertical frame 5a and a laser mounting plate 5b. The vertical frame 5a is vertically arranged and its bottom is connected to the slider of the lead screw slide table 1. The laser mounting plate 5b is horizontally arranged and has bolt holes 13 for connecting the laser. The bottom of the laser has a straight groove 14. The laser 6 is connected to the laser mounting plate 5b by bolts 15, and the bolts 15 are connected in the straight groove 14 of the laser 6. There is a nut in the straight groove connected to the bolts 15, and the nut can slide in the straight groove 14. The vertical frame 5a and the laser mounting plate 5b are connected by an adjustment mechanism 16, which is used to adjust the height of the laser mounting plate 5b.

[0032] With the above settings, during the installation process, when bolt 15 is loosened, the nut connected to the bolt in the straight groove 14 can slide freely in the straight groove, which allows the front and rear positions of the laser to be adjusted. The front and rear positions refer to the direction faced by the operator when standing near the side of the tray. After the front and rear positions are adjusted, bolt 15 is tightened. At this time, the laser 6 and the laser mounting plate 5b are relatively fixed. The height of the laser can then be adjusted by adjusting mechanism 16.

[0033] Please see Figure 1 and Figure 4The camera mounting bracket 3 includes a column 3a, a base plate 3b, an adjustment mechanism 16, and a camera mounting seat 3c. The column 3a is vertically fixed on the slider of the lead screw slide table 2. The base plate 3b is mounted on the column 3a and is horizontally set. There are two adjustment mechanisms 16 connected to each other. Specifically, one adjustment mechanism is horizontally set and used to adjust the front-to-back position, and the other adjustment mechanism is vertically set and used to adjust the vertical height. The camera mounting seat 3c is connected to the vertically set adjustment mechanism 16. In this way, the two adjustment mechanisms 16 are used to adjust the vertical height and front-to-back position of the camera mounting seat 3c, respectively. The front-to-back position is the same as the aforementioned front-to-back position. Through the above settings, the front-to-back position and vertical height of the camera can be adjusted in combination, which can effectively ensure accuracy.

[0034] Please see 1 and Figure 5 The pallet rack 7 includes a base 7a, side plates 7b, and an adjustment mechanism 16. The base 7a is horizontally positioned for placing the pallet 8. Side plates 6b are provided on both sides of the base 7a to align the position of the pallet placed on the base. In actual use, when the pallet 8 is placed on the base 7a, the two sides are aligned with the side plates 6a, so that the position of the pallet placed on the base is relatively fixed each time. The bottom of the base 7a is connected to the machine base 1 through the adjustment mechanism 16. The adjustment mechanism 16 is vertically positioned for adjusting the height of the base 7a.

[0035] Please see Figure 2 , Figure 4 and Figure 5 The adjusting mechanism 16 includes a fixed block 16a, a movable block 16b, and a limiting mechanism 16c. The fixed block 16a and the movable block 16b are connected by a set of cross roller guides 16d, so that the fixed block 16a and the movable block 16b can slide along the direction of the cross roller guides. The limiting mechanism 16c is used to adjust the relative position of the fixed block 16a and the movable block 16b and to fix them.

[0036] Specifically, in the laser mounting bracket 5, the fixed block 16a and the upright bracket 5a are fixedly connected by bolts. The relative sliding direction between the fixed block 16a and the movable block 16b is the up and down direction. The laser mounting plate 5b is also installed on the movable block by bolts. With the above settings, the above scheme can specifically achieve the purpose of adjusting the height of the laser by adjusting the adjustment mechanism 16.

[0037] The camera mounting bracket has two adjustment mechanisms. One adjustment mechanism is horizontally set, with its fixed block 16a fixed to the base plate. The relative sliding direction of the fixed block and the movable block of this adjustment mechanism is in the front-back direction. The other adjustment mechanism is vertically set, with its fixed block mounted on the movable block of the horizontal adjustment mechanism. The relative sliding direction of the fixed block and the movable block of the vertical adjustment mechanism is in the opposite direction to the vertical direction. By cooperating with each other, the front-back position and vertical height of the camera can be adjusted.

[0038] In the pallet frame, the fixed block 16a of the adjustment mechanism is mounted on the machine base, and the movable block is connected to the back of the base 7a. The height of the pallet frame can be adjusted by the adjustment mechanism.

[0039] Please see Figure 2 and Figure 4 The first type of limiting mechanism 16c specifically includes an adjusting block 16ca, a connecting shaft 16cb, and a locking bolt 16cc. The adjusting block 16ca and the connecting shaft 16cb are fixedly connected to the fixed block 16a and the movable block 16b, respectively. The adjusting block 16ca has a slotted circular hole, through which the connecting shaft 16cb passes. The locking bolt 16cc is provided at the slotted position of the circular hole in the adjusting block 16ca. When the locking bolt 16cc is tightened, the adjusting block 16ca and the connecting shaft 16cb are relatively fixed, and the corresponding fixed block 16a and the movable block 16b are relatively fixed. When the locking bolt 16cc is loosened, the adjusting block 16ca can slide relative to the connecting shaft 16cb, and the corresponding fixed block 16a and the movable block 16b can slide relative to each other.

[0040] This utility model also proposes a second limiting mechanism structure, please refer to the details. Figure 4 and Figure 5 The limiting mechanism 16c includes a first connecting block 16cd, a second connecting block 16ce, and an adjusting bolt 16cf. The first connecting block 16cd and the second connecting block 16ce are fixedly connected to the fixed block 16a and the movable block 16b, respectively. The first connecting block 16cd is provided with a bolt hole, and the adjusting bolt 16cf is provided in the bolt hole. One end of the adjusting bolt 16cf is connected to the second connecting block 16ce, and the adjusting bolt 16cf can rotate freely. By rotating the adjusting bolt 16cf, the relative position of the first connecting block 16cd and the second connecting block 16ce is adjusted, thereby adjusting the relative position of the corresponding fixed block 16a and movable block 16b.

[0041] It is understandable that, in the above scheme, the first connecting block 16cd and the second connecting block 16ce can be fixedly connected to the movable block 16b and the fixed block 16a respectively. The second connecting block 16cd is provided with bolt holes, and the adjusting bolt 16cf is provided in the bolt holes. One end of the adjusting bolt 16cf is connected to the first connecting block 16cd, and the adjusting bolt 16cf can rotate freely. By rotating the adjusting bolt 16cf, the relative position of the first connecting block 16cd and the second connecting block 16ce is adjusted, thereby adjusting the relative position of the corresponding fixed block 16a and movable block 16b.

[0042] Specifically, in the laser mounting bracket, the adjustment mechanism adopts the first type of limiting mechanism; in the camera mounting bracket, the vertically set adjustment mechanism also adopts the first type of limiting mechanism, while the horizontally set adjustment mechanism adopts the second type of limiting mechanism; in the tray bracket, the adjustment mechanism specifically adopts the second type of limiting mechanism. Through these settings, the laser can be adjusted vertically, the camera can be adjusted vertically and horizontally, and the tray can also be adjusted vertically.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
