Description

Technical Field

[0001] This utility model relates to the field of medal processing technology, specifically to a medal visual painting mechanism. Background Technology

[0002] During the medal manufacturing process, the surface of the die-cast medal needs to be painted. Painting is an extremely important part of the medal manufacturing process, as the effect of painting directly affects the visual presentation and product quality of the medal. In order to reduce the impact of painting on the quality of the medal, staff need to inspect and apply additional paint to the painted medals.

[0003] Traditional plating processes typically involve placing medals in batches on a plating rack, where workers inspect the surface of the medals. If a medal is found to be defective, it is then plating with a plating head. However, prolonged inspection can lead to visual fatigue among workers, reducing the effectiveness of the inspection. Furthermore, fatigue can cause defects such as missed areas, overflow, and bubbles, resulting in a decline in the production quality of the medals. Therefore, we need to propose a visual plating mechanism for medals. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a visual painting mechanism for medals, including a painting platform 1 and an adjustment mechanism 2 for changing the painting position. The upper surface of the painting platform 1 is provided with a painting rack 3 for placing the medal, and the painting rack 3 is hollow. The top of the painting platform 1 is equipped with a fixing mechanism 4 for fixing the painting rack 3. The adjustment mechanism 2 is installed on the top of the painting platform 1 through a mounting frame 5. The bottom of the adjustment mechanism 2 is provided with a connecting frame 6. The inner cavity of the connecting frame 6 is equipped with a painting head 7. Both ends of the painting head 7 are connected to a storage bottle 8 for storing paint, and the storage bottle 8 is transparent. The top of the mounting frame 5 is also equipped with an area array camera 9 for inspecting the painting defects on the surface of the medal.

[0023] During the painting process, the painting frame 3 is first placed on the painting table 1, and then the position of the fixing mechanism 4 is adjusted to fix the painting frame 3. Next, the painted medal is placed on the painting frame 3, and the area scan camera 9 is activated to take pictures of the medal surface. The area scan camera 9 transmits the images to the control computer via a signal cable. The control computer compares the captured images with the finished product images, identifies medals with paint defects, and alerts the staff. Then, the staff operates the adjustment mechanism 2 to adjust the setting of the painting head 7, moving the painting head 7 above the medal to perform the painting operation. This method improves the inspection effect of the paint surface during medal production, reduces the labor intensity of the staff, and improves the production quality of the medals.

[0024] The area scan camera 9 is connected to the power supply equipment via a power cord and to the control computer via a signal cable. The system connection and cooperation between the area scan camera 9 and the control computer is a mature existing technology. The model of the area scan camera 9 is set as MV-HS1200GM / C2.

[0025] The surface of the paint dotting head 7 has a connection port. The connector of the paint dotting head 7 is connected to the connecting pipe of the compressed air equipment. The compressed air equipment injects air into the paint dotting head 7 through the connecting pipe, so that the paint dotting head 7 performs paint dotting work on the surface of the medal.

[0026] The adjustment mechanism 2 includes a transverse electric slide 21 bolted to the mounting frame 5. A slide block 22 is slidably connected to the transverse electric slide 21. A support base 23 is bolted to the top of the slide block 22. The other end of the support base 23 is slidably connected to the surface of the mounting frame 5. An adjustment component for longitudinally adjusting the paint dotting position is provided at the top of the support base 23. When the transverse electric slide 21 is activated, the slide block 22 slides on the surface. The sliding of the slide block 22 drives the adjustment component at the top to slide through the support base 23, causing the adjustment component to move with the connecting frame 6 to achieve transverse adjustment of the paint dotting head 7 position. Then, the adjustment component is activated to drive the paint dotting head 7 to move longitudinally, achieving longitudinal adjustment of the paint dotting head 7 position. Through the cooperation with the adjustment component, the flexible adjustment of the paint dotting head 7 position is achieved, which can adapt to medals of different specifications and different paint dotting position requirements, improving the versatility of the mechanism. The sliding connection between the support base 23 and the surface of the mounting frame 5 ensures the stability of the adjustment process and makes the paint dotting position more accurate.

[0027] The adjustment assembly includes a longitudinal electric slide 24, which is bolted to the top of the support base 23. A second slide 25 is slidably connected to the longitudinal electric slide 24. A connecting column is bolted to the surface of the second slide 25, and the bottom end of the connecting column is bolted to the connecting frame 6. When the longitudinal electric slide is activated, the second slide 25 is moved, so that the second slide 25 drives the connecting frame 6 at the bottom end to perform longitudinal adjustment through the connecting column, thereby realizing the longitudinal change of the position of the paint dispensing head 7. Through the cooperation of the longitudinal electric slide 24 and the second slide 25, the accuracy and flexibility of paint dispensing are further improved, which helps to improve the quality and efficiency of paint dispensing.

[0028] The surface of the support base 23 is provided with a sliding groove, and the inner cavity of the sliding groove is provided with a sliding rail 11 that is adapted to the sliding groove. The sliding rail 11 is bolted to the inner cavity of the mounting bracket 5. When the support base 23 moves laterally under the drive of the slide base 22, the support base 23 slides on the surface of the sliding rail 11 through the sliding groove. The cooperation between the sliding rail 11 and the sliding groove can provide support force to the other end of the support base 23, effectively enhancing the stability and smoothness of the support base 23 when moving laterally, and avoiding the support base 23 from deviating or getting stuck during the movement.

[0029] The fixing mechanism 4 includes fixing plates 41 located on both sides of the paint dispensing table 1, and the fixing plates 41 are L-shaped. The surface of the fixing plates 41 is provided with a positioning structure for positioning the fixing plates 41. The bottom end of the fixing plates 41 is integrally formed with a support column 42. The outer wall of the paint dispensing table 1 is provided with a connecting groove 43 that is adapted to the support column 42. When the paint dispensing frame 3 is placed on the paint dispensing table 1, the support column 42 is inserted into the inner cavity of the connecting groove 43. At this time, the inner cavity of the fixing plate 41 is exactly in contact with the surface of the paint dispensing frame 3. The top of the paint dispensing frame 3 is fixed by the fixing plate 41, and the position of the fixing plate 41 is fixed by the positioning structure, so as to prevent the fixing plate 41 from separating from the paint dispensing frame 3, thereby improving the stability of the paint dispensing frame 3 on the paint dispensing table 1 and preventing the position of the paint dispensing frame 3 from changing due to external collisions.

[0030] The positioning structure includes a positioning hole 44 on the surface of the fixing plate 41. A positioning pin is inserted and slidably inserted into the inner cavity of the positioning hole 44. The surface of the paint dispensing frame 3 is provided with a fixing hole 45 that matches the positioning pin. When the inner side wall of the fixing plate 41 is in contact with the surface of the paint dispensing frame 3, the positioning pin is inserted into the inner cavity of the positioning hole 44 and passes through the inner cavity of the fixing hole 45 to achieve the positioning of the fixing plate 41 on the paint dispensing frame 3, so as to prevent the position of the fixing plate 41 from changing. With the cooperation of the bottom support column 42, a force can be applied to the top of the paint dispensing frame 3, which improves the stability of the paint dispensing frame 3 and the surface of the paint dispensing table 1.

[0031] The lower surface of the paint dispensing frame 3 is provided with a fixing groove 12. The inner cavity of the fixing groove 12 is provided with a positioning post 13 that is adapted to the fixing groove 12. The positioning post 13 is welded and fixed to the upper surface of the paint dispensing table 1. Through the cooperation of the fixing groove 12 and the positioning post 13, the connection between the paint dispensing frame 3 and the paint dispensing table 1 can be supported, preventing the angular position of the paint dispensing frame 3 on the paint dispensing table 1 from shifting. This allows for quick initial positioning of the paint dispensing frame 3 on the paint dispensing table 1, making the installation of the paint dispensing frame 3 more convenient. At the same time, this structure enhances the stability of the paint dispensing frame 3 during the paint dispensing process, preventing the paint dispensing frame 3 from shaking and affecting the paint dispensing quality.

[0032] Both the horizontal electric slide 21 and the vertical electric slide 24 are connected to the power supply equipment via power cords. The horizontal electric slide 21 and the vertical electric slide 24 are also connected to control buttons via power cords. The model of the horizontal electric slide 21 is set as: N3-X6030 of Norp Precision, and the model of the vertical electric slide 24 is set as: LES8RK-50 of SMC.

[0033] In practical use: When performing the painting work, first place the painting frame 3 on the painting table 1, insert the support column 42 into the inner cavity of the fixing groove 12, and complete the step-by-step combination of the painting table 1 and the painting frame 3. Then, take the fixing plate 41, insert the support column 42 into the inner cavity of the connecting groove 43, and make the inner side wall of the fixing plate 41 fit against the surface of the painting frame 3, so that the positioning hole 44 and the fixing hole 45 are aligned. Then, insert the positioning pin into the positioning hole 44 and extend it into the inner cavity of the fixing hole 45 to position the fixing plate 41 on the painting frame 3 and support the painting frame 3. Then, place the medals on the painting frame 3 in sequence, start the area scan camera 9 to take pictures of the surface of the medals, and transmit the image of the area scan camera 9 to the control computer through the signal line. The control computer compares the captured image with the finished product image, and identifies medals with defects in the paint surface after comparison, and prompts the staff.

[0034] Finally, based on the medal's position, the staff activates the horizontal electric slide 21, which moves the slide 22. The slide 22, through the support 23, moves the paint applicator 7 laterally, thus adjusting the position of the paint applicator 7. Then, the vertical electric slide 24 is activated, which, through the slide 25, moves the connecting column, thus adjusting the position of the paint applicator 7 vertically. When the paint applicator 7 is directly above the medal, the medal can be painted. This method improves the inspection effect of the paint surface during medal production, reduces the labor intensity of the staff, and improves the production quality of the medal.
