[0025] Reference Figures 1 to 9This application provides an automatic feeding device, including: a base 100 with a feeding station, a material tray placed on the feeding station, and multiple rows of capacitors placed on the material tray; a transfer mechanism 200, including a rotating component 210 and a conveying component 220, the rotating component 210 being disposed on the base 100 and located on one side of the material tray, the conveying component 220 being disposed on the rotating component 210, the rotating component 210 driving the conveying component 220 to rotate so that the conveying component 220 is connected to or perpendicular to the conveyor belt 400 of the sandblasting machine; and a picking mechanism 300, erected between the feeding station and the transfer mechanism 200, the picking mechanism 300 including a moving component 310 and a picking component 320, the picking component 320 being disposed on the moving component 310, the picking component 320 including multiple picking parts 321 arranged in a row, the moving component 310 driving the picking component 320 to move, so that the picking parts 321 pick up the capacitors on the material tray and transfer them to the conveying component 220.

[0026] During operation, a tray filled with capacitors is placed at the loading station. Then, the motion component 310 moves the picking component 320 above the loading station so that the picking component 320 can pick up the capacitors from the tray. Next, the motion component 310 moves the picking component 320 above the conveying component 220, at which point the conveying component 220 is perpendicular to the conveyor belt 400 of the sandblasting machine, allowing the picking component 320 to place the capacitors on the conveying component 220. Finally, the rotation component 210 rotates the conveying component 220, connecting the conveying component 220 with the conveyor belt 400 of the sandblasting machine. At this time, the conveying component 220 moves the capacitors, allowing them to enter the conveyor belt 400 to await sandblasting, thus completing the automatic loading of the capacitors. By setting up the feeding mechanism 300, the capacitors can be automatically fed without manual operation, reducing labor intensity and improving work efficiency. By setting the conveying component 220 on the rotating component 210, the conveying component 220 can be connected to or perpendicular to the conveyor belt 400 of the sandblasting machine, thereby reducing the space occupied and making the structure reasonable and compact.

[0027] Reference Figures 1 to 4 The rotating assembly 210 includes a rotating shaft 211 and a driving component 212. The rotating shaft 211 is rotatably mounted on the base 100, and the driving component 212 is connected to the rotating shaft 211. The driving component 212 drives the rotating shaft 211 to rotate, which in turn drives the conveying assembly 220 to rotate, thereby enabling the conveying assembly 220 to connect with or be perpendicular to the conveyor belt 400. Specifically, the driving component 212 includes a cam 213 and a cylinder 214. The cam 213 is mounted on the rotating shaft 211, and the cylinder 214 is connected to the cam 213. The cylinder 214 drives the cam 213 to rotate, which in turn drives the rotating shaft 211 to rotate the conveying assembly 220. The structure is simple and the operation is stable.

[0028] It should be noted that the driving component 212 can also be a motor, which drives the rotating shaft 211 to rotate, so that the rotating shaft 211 drives the conveying component 220 to rotate. The structure is simple and the operation is convenient.

[0029] Reference Figures 1 to 5 The conveying assembly 220 includes a mounting frame 221, a conveyor belt 222, and a detection element 223. The mounting frame 221 is connected to the rotating assembly 210. The conveyor belt 222 is mounted on the mounting frame 221 and has a feeding end and a discharging end. The detection element 223 is located at the feeding end and is used to detect the presence or absence of capacitors at the feeding end. The discharging end corresponds to the conveyor belt 400. Each detection element 223 corresponds to one capacitor. After the feeding assembly 320 places the capacitor on the conveyor belt 222, the capacitor is detected by the detection component 223. If there is no problem, the rotating assembly 210 drives the mounting frame 221 to rotate, so that the conveyor belt 222 connects with the conveyor belt 400 and the capacitor is transported onto the conveyor belt 400. If a missing capacitor is detected, it means that the feeding assembly 320 has not completely picked up the capacitor or that a capacitor has fallen. At this time, an alarm will be triggered and the machine will stop until the problem is resolved before it can resume normal operation. This can prevent the missing capacitor from affecting the subsequent normal automatic feeding.

[0030] It should be noted that the alarm and shutdown settings can be configured using conventional alarm devices and programs, which are existing technologies and will not be elaborated upon here.

[0031] It is conceivable that a connecting plate 224 is provided at the end of the discharge end, which can connect to the conveyor belt 400, thereby improving the stability of the capacitor entering the conveyor belt 400 from the conveyor belt 222 and preventing the capacitor from getting stuck between the conveyor belt 222 and the conveyor belt 400. It is easy to understand that guide plates 225 are provided on both sides of the discharge end to guide the capacitor, ensuring the stability and reliability of the capacitor transport. Furthermore, the guide plates 225 are adjustable to accommodate capacitors of different specifications, expanding the range of applications. Specifically, the mounting frame 221 is rotatably equipped with a double-rotating screw 226, and the guide plates 225 are respectively sleeved on both ends of the double-rotating screw 226. A handwheel 227 is provided at the end of the double-rotating screw 226. Operating the handwheel 227 rotates the double-rotating screw 226, causing the guide plates 225 to move closer or further apart, thereby adjusting the distance between the guide plates 225. The structure is simple and the operation is convenient.

[0032] It should be noted that the distance between the guide plates 225 can also be adjusted by means of structures such as electric push rods, and this application does not limit this.

[0033] Reference Figures 1 to 3 , Figure 6The motion assembly 310 includes a horizontal movement unit 311 and a vertical movement unit 312. The horizontal movement units 311 are located on both sides of the base 100 and are connected by a crossbeam. The vertical movement unit 312 is located on the crossbeam, and the material handling assembly 320 is located on the vertical movement unit 312. Both the horizontal movement unit 311 and the vertical movement unit 312 can employ a screw and nut mechanism, a gear and rack mechanism, or a cylinder 214, etc., and this application does not impose any limitations on these. Specifically, the horizontal movement unit 311 drives the vertical movement unit 312 to move, positioning the material handling assembly 320 above the loading station or conveying assembly 220. Subsequently, the vertical movement unit 312 drives the material handling assembly 320 to move closer to (or further away from) the loading station or conveying assembly 220, thereby achieving the handling (or unloading) of capacitors. The structure is simple and the operation is convenient.

[0034] It should be noted that the motion component 310 can also be configured as a multi-axis robot. Those skilled in the art can make reasonable choices based on the actual situation, and this application does not impose any restrictions on this.

[0035] Reference Figures 1 to 3 , Figure 6 and Figure 7 In this embodiment, the material-grabbing part 321 is configured as a suction cup. Specifically, the material-grabbing assembly 320 further includes a first fixing plate 322, which is disposed on the vertical moving unit 312. The material-grabbing part 321 is provided with a bracket, which is connected to the first fixing plate 322, and the suction cup is disposed on the bracket. By using a suction cup to pick up the capacitor, it is possible to prevent the capacitor from being scratched and improve product quality. Furthermore, the bracket is provided with a spring, which enables the suction cup to have a cushioning effect when picking up the capacitor, thus preventing damage to the capacitor.

[0036] Of course, the material handling section 321 can also be configured as a gripper or the like, as long as it can handle the capacitors. This application does not impose any restrictions on this.

[0037] Understandably, the feeding assembly 320 also includes a pressing part 323, which is located behind the feeding part 321. The pressing part 323 is used to press the capacitors in the rear row. When the feeding part 321 picks up the capacitors, the pressing part 323 also presses the capacitors in the rear row, thereby preventing the capacitors in the rear row from shifting position and improving stability and reliability.

[0038] Reference Figures 1 to 3 , Figure 8In some embodiments of this application, the automatic feeding device further includes a feeding mechanism 500, which includes a lifting component 510 and a material support component 520. The lifting component 510 is disposed on the machine base 100, and the material support component 520 is disposed on the lifting component 510. The material tray is placed on the material support component 520, and the lifting component 510 drives the material support component 520 to move so that the material tray reaches the feeding station. The lifting component 510 is configured as a screw and nut mating structure, a gear and rack mating structure, or a cylinder 214, etc. Specifically, the lifting component 510 rises, causing the material support component to drive the material tray upward until the material tray reaches the feeding station.

[0039] As can be imagined, the loading station is equipped with sensors, which are connected to the feeding mechanism 500 and the picking mechanism 300, respectively. The sensors detect whether there are capacitors in the trays at the loading station. When all the capacitors in the tray are removed, the sensor sends a signal to the worker to remove the empty tray. Then, the feeding mechanism 500 delivers a new tray containing capacitors to the loading station. At this point, the sensor detects capacitors again, and the picking mechanism 300 resumes operation and picks up the capacitors.

[0040] Furthermore, the feeding mechanism 500 also includes a tray feeding assembly 530. The base 100 is provided with a storage station, which is located on one side of the lifting assembly 510. The storage station is equipped with a placement plate, and the tray feeding assembly 530 is used to push the tray from the placement plate onto the material support. Specifically, the tray feeding assembly 530 includes a lifting unit 531 and a push plate 532. The lifting unit 531 is connected to the placement plate, and the push plate 532 is slidably disposed on one side of the placement plate. The sliding of both the lifting unit 531 and the push plate 532 is driven by the cylinder 214. The lifting unit 531 drives the placement plate to rise and fall, so that the tray at the top of the placement plate corresponds to the push plate 532. At this time, the material support 520 also corresponds to the tray. Then, the push plate 532 slides to push the tray onto the material support 520, thereby realizing automatic feeding of the tray.

[0041] Of course, the push plate 532 can also be replaced by a clamp. The clamp clamps the material tray and pull the material tray onto the material support 520. The structure is simple and the operation is convenient.

[0042] Reference Figures 1 to 3 , Figure 9In some embodiments of this application, the automatic feeding device further includes a tray removal mechanism 600. The tray removal mechanism 600 includes a sliding component 610 and a clamping component 620. The sliding component 610 is disposed on both sides of the tray, and the clamping component 620 is disposed on the sliding component 610. The clamping component 620 is used to clamp the tray, and the sliding component 610 drives the clamping component 620 to move to output the empty tray to the feeding station. A discharging station is provided on one side of the feeding station. Optionally, the sliding component 610 is configured as a screw and nut mating structure, a gear and rack mating structure, or a cylinder 214, etc., and the clamping component 620 is configured as a gripper. In this embodiment, a sensor can be connected to the tray removal mechanism 600. When the capacitors on the tray are removed, the sensor sends a feedback signal, and the tray removal mechanism 600 operates, causing the sliding component 610 to drive the clamping component 620 to move to send the empty tray into the discharging station.

[0043] It is easy to understand that the unloading station is equipped with a tray lowering assembly 630, which includes a vertical motion unit 631 and a fixing unit 632. The fixing unit 632 is located above the vertical motion unit 631 and is used to fix the tray. The vertical motion unit 631 drives the fixing unit 632 to move so that the fixing unit 632 lowers the tray. The vertical motion unit 631 can be configured with a screw and nut, a gear and rack, or a cylinder 214, etc. The fixing unit 632 consists of two clamping blocks that can move closer or further apart. When the sliding assembly 610 drives the clamping assembly 620 to move and transport the tray above the unloading station, the fixing unit 632 fixes the tray, and the clamping assembly 620 releases the tray. Then, the vertical motion unit 631 drives the clamping assembly 620 to move, so that the tray is stably stacked on the unloading station. By setting up the tray lowering assembly 630, the stacking of trays can be achieved, making the operation simple.

[0044] A second aspect of this application provides a sandblasting machine, including the automatic feeding device described in the first aspect of this application.

[0045] When the automatic feeding device described in the first aspect of this application is applied to a sandblasting machine, during operation, a tray filled with capacitors is placed at the feeding station; then, the motion component 310 drives the picking component 320 to move above the feeding station so that the picking component 320 can pick up the capacitors from the tray; next, the motion component 310 drives the picking component 320 to move above the conveying component 220, at which point the conveying component 220 is perpendicular to the conveyor belt 400 of the sandblasting machine, so that the picking component 320 can place the capacitors on the conveying component 220; finally, the rotation component 210 drives the conveying component 220 to rotate, so that the conveying component 220 connects with the conveyor belt 400 of the sandblasting machine. At this time, the conveying component 220 drives the capacitors to move, so that the capacitors enter the conveyor belt 400 to wait for sandblasting, thereby completing the automatic feeding of capacitors. By setting up the material feeding mechanism 300, the capacitors can be automatically fed without manual operation, reducing labor intensity and improving work efficiency. By setting the conveying component 220 on the rotating component 210, the conveying component 220 can be connected to or perpendicular to the conveyor belt 400 of the sandblasting machine, thereby reducing the space occupied and making the structure reasonable and compact.

[0046] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
