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.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a fixture for programming PCBA boards, including a programming table 1. A positioning cover 3 is fixedly connected to the outer side of the programming table 1. A first electric telescopic rod 10 is fixedly connected to the left and right sides of the inner wall of the positioning cover 3. The bottom of the first electric telescopic rod 10 passes through the programming table 1 and is fixedly connected to a base plate 4. Activating the first electric telescopic rod 10 can drive the base plate 4 to move up and down. Multiple spring blocks 5 are fixedly connected to the top of the base plate 4 around its perimeter. The top of the spring blocks 5 passes through the programming table 1. The position of the workpiece fixed by the device can be restricted by the restriction of the spring blocks 5. A rack 6 is fixedly connected to the front and rear sides of the middle part of the base plate 4. The inner wall of the programming table 1 around its perimeter... Gears 7 are fixedly connected to each of the components. Gears 7 mesh with racks 6. When racks 6 move, gears 7 can be driven to move through meshing. The outer side of gears 7 passes through the burning station 1 and is fixedly connected to a first rotating plate 8. A positioning plate 9 is rotatably connected to the outer side of the first rotating plate 8. When the first rotating plate 8 moves, it can drive the positioning plate 9 on it to fix the workpiece. A second electric telescopic rod 11 is fixedly connected to the top of the inner wall of the positioning cover 3. A burning mold 12 is fixedly connected to the bottom end of the second electric telescopic rod 11. The workpiece can be burned through the burning mold 12. A cleaning mechanism 2 is provided on the outer side of the burning station 1. The cleaning mechanism 2 is used to clean the burning station 1 before burning.

[0033] Specifically, the workpiece to be burned is placed on top of the burning table 1. Then, the first electric telescopic rod 10 is activated to move the base plate 4 up and down. At this time, multiple spring blocks 5 on it will extend out of the top of the burning table 1. Due to the elasticity of the spring blocks 5, the spring blocks 5 that are blocked by the workpiece will not extend out, while the extended spring blocks 5 can fix the workpiece to prevent it from tilting. At the same time, the movement of the base plate 4 will drive the rack 6 to move, and through meshing transmission, drive the gear 7 and the first rotating plate 8 on it to move, so as to pre-position the workpiece through the positioning plate 9. Then, the second electric telescopic rod 11 is activated to move the burning mold 12 to burn the workpiece.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The cleaning mechanism 2 includes two second rotating plates 204, which are respectively disposed on the front and rear sides of the burning station 1. The bottom of the second rotating plate 204 passes through the burning station 1 and is fixedly connected to the corresponding gear 7. As the gear 7 rotates, it can simultaneously drive the second rotating plate 204 to rotate. The top of the second rotating plate 204 is rotatably connected to a rotating block 205. The top of the rotating block 205 is slidably connected to a cleaning roller 206. The outer side of the cleaning roller 206 is slidably connected to a filter screen 203. The filter screen 203 can be cleaned by moving the cleaning roller 206. The front and rear sides of the outer wall of the burning station 1 are fixedly connected to a cleaning cover 201. The inner side of the cleaning cover 201 is fixedly connected to a filter screen 203. The outer side of the cleaning cover 201 is fixedly connected to an air pump 202. The output end of the air pump 202 passes through the cleaning cover 201. Starting the air pump 202 can drive the airflow and impurities in it into the cleaning cover 201.

[0035] Specifically, by activating the air pump 202, airflow and impurities in it can be driven into the cleaning hood 201, and simultaneously intercepted by the filter screen 203 to prevent them from being sucked into the air pump 202 and interfering with its operation. At this time, as the gear 7 rotates, it can drive the second rotating plate 204 to rotate, and at the same time, the rotating block 205 on it can drive the cleaning roller 206 on it to move up and down to scrape off the impurities attached to the filter screen 203. This can improve the burning effect while preventing the attached impurities from affecting the cleaning effect.

[0036] Reference Figure 1 , Figure 2 and Figure 3The bottom left and right sides of the cleaning cover 201 are fixedly connected to the brackets 20, and the outer side of the brackets 20 is fixedly connected to the burning table 1. The brackets 20 can improve the firmness between the cleaning cover 201 and the burning table 1. The outer left and right sides of the positioning cover 3 are fixedly connected to the handles 13, and the outer side of the handles 13 is fixedly connected to the protective sleeves 14, which can facilitate the handling and gripping of the device through the handles 13. The top left and right sides of the positioning cover 3 are slidably connected to the U-shaped rods 16, and the bottom of the U-shaped rods 16 is fixedly connected to the burning mold 12, which can improve the stability of the burning mold 12 when it moves.

[0037] Specifically, the bracket 20 can improve the firmness of the fixing between the cleaning cover 201 and the burning table 1. The handle 13 and the protective sleeve 14 on it can facilitate the holding and carrying of the device and improve the comfort of holding it. The sliding of the U-shaped rod 16 and the positioning cover 3 can improve the stability of the burning mold 12 when it moves.

[0038] Reference Figure 2 , Figure 3 and Figure 4 The inner wall of the positioning cover 3 is provided with sliding grooves 17 on all four sides. The outer side of the first electric telescopic rod 10 is slidably connected to the sliding grooves 17, which can improve the stability of the base plate 4 when moving. The outer wall of the burning table 1 is fixedly connected with positioning blocks 18 on all four sides. The outer side of the positioning blocks 18 is provided with positioning holes 19, which can facilitate the installation and fixation of the device. The bottom right side of the positioning cover 3 is fixedly connected with a controller 15. The controller 15 is electrically connected to the first electric telescopic rod 10, the second electric telescopic rod 11 and the air pump 202 respectively. The controller 15 can control the start and operation of the first electric telescopic rod 10, the second electric telescopic rod 11 and the air pump 202.

[0039] Specifically, the sliding groove 17 can improve the stability of the base plate 4 when moving. By installing threaded parts in the positioning holes 19 on the positioning block 18, the device can be easily installed and fixed. The controller 15 can control the start and operation of the first electric telescopic rod 10, the second electric telescopic rod 11 and the air pump 202 respectively.

[0040] Working Principle: Before using the device, first place the workpiece to be burned stably on top of the burning table 1. Then, activate the first electric telescopic rod 10, which will move the base plate 4 vertically up and down. During this process, multiple spring blocks 5 on the base plate 4 will move accordingly, extending towards the top of the burning table 1. Due to the elasticity of the spring blocks 5, when they are blocked by the workpiece, these spring blocks 5 will not extend, while those that are not blocked will extend smoothly. These extended spring blocks 5 can fix the workpiece, effectively... To prevent the workpiece from tilting during subsequent operations, the movement of the base plate 4 is not an isolated action; it simultaneously moves the rack 6. Since there is a meshing transmission relationship between the rack 6 and the gear 7, the movement of the rack 6 further drives the gear 7 and the first rotating plate 8 mounted on the gear 7 to move. Through this linkage mechanism, the workpiece can be pre-positioned with the help of the positioning plate 9, preparing for the subsequent burning operation. Finally, the second electric telescopic rod 11 is activated, which moves the burning mold 12 to accurately position it at the workpiece location for the burning operation.

[0041] When the air pump 202 is started, it begins to work, causing airflow. During this airflow, impurities carried by the airflow are drawn into the cleaning hood 201. At this point, the filter 203 inside the cleaning hood 201 plays a crucial role, successfully intercepting these impurities and preventing them from being sucked into the air pump 202. If impurities enter the air pump 202, they may interfere with its normal operation, affecting the overall stability and efficiency of the equipment. Simultaneously, during operation, when the gear 7 rotates, it drives the associated second rotating plate 204 to rotate as well. The second rotating plate 204 is equipped with rotating blocks 205. As the second rotating plate 204 rotates, the rotating block 205 drives the cleaning roller 206 to move up and down. The up and down movement of the cleaning roller 206 is of great significance. It can scrape off the impurities attached to the filter screen 203, clean the impurities in time, improve the effect of the entire burning process, and ensure the cleanliness and stability of the burning environment. On the other hand, by continuously scraping off the impurities attached to the filter screen 203, it can effectively prevent the excessive accumulation of impurities from negatively affecting the cleaning effect, and ensure that the filter screen 203 always maintains good filtration performance, thereby maintaining the normal air intake efficiency of the air pump 202 and the overall operating effect of the equipment, providing a strong guarantee for the smooth progress of the burning work.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
