Description

Technical Field

[0001] This utility model relates to the field of feeding technology, specifically to an automatic powder feeding mechanism. Background Technology

[0002] In fields such as electronic components, semiconductor packaging, or powder metallurgy, it is often necessary to apply powder coating to the substrate surface.

[0003] Currently, most equipment relies on operators to manually place individual substrates one by one onto the conveyor belt or fixture. The instability of the manual operation rhythm directly restricts the operating efficiency of the entire production line. Existing feeding mechanisms generally lack a precise one-by-one separation mechanism, which easily leads to the simultaneous feeding of two or more substrates, resulting in processing failures, equipment jams, or even damage in subsequent powder coating processes.

[0004] Therefore, an automatic powder feeding mechanism is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic powder feeding mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: An automatic powder feeding mechanism includes a feeding frame assembly, on which several sets of material box assemblies are fixedly installed for storing substrates. The feeding frame assembly and the material box assemblies are provided with a feeding assembly for vertically lifting the substrates placed in the material box assemblies. A moving mechanism is fixedly installed on the feeding frame assembly. Hydraulic rods are fixedly installed on both ends of the moving part of the moving mechanism. The telescopic ends of the hydraulic rods are fixedly connected to a conveying assembly for negative pressure suction of the uppermost substrate of the material box assembly.

[0007] Furthermore, a material preparation platform assembly is fixedly installed on one side of the feeding frame assembly, and a photoelectric switch is fixedly installed on the feeding frame assembly via a photoelectric bracket, with the photoelectric switch being flush with the top surface of the material box assembly.

[0008] Furthermore, the feeding assembly includes a first servo motor fixedly mounted on the feeding frame assembly. A first threaded rod is rotatably inserted into the bottom of the feeding frame assembly. A first synchronous pulley is fixedly sleeved on the output end of the first servo motor and the end of the first threaded rod. A first synchronous belt is sleeved on the two sets of first synchronous pulleys. A feeding moving frame is threadedly sleeved on the surface of the first threaded rod. The feeding moving frame and the rod on the feeding frame assembly are slidably sleeved. A feeding pusher is fixedly mounted on the top surface of the feeding moving frame, and a pusher plate is fixedly mounted on the top of the feeding pusher.

[0009] Furthermore, the bottom surface of the material box assembly is open, the feeding pusher is movably inserted into the opening, and the pusher plate at the top of the feeding pusher is vertically inserted into the material box assembly.

[0010] Furthermore, the moving mechanism includes a support frame, and a second threaded rod is rotatably inserted into the top surface of the support frame and the feeding frame assembly via a bearing seat. A second servo motor is fixedly mounted on the feeding frame assembly via a mounting bracket. A second synchronous pulley is fixedly mounted on the output end of the second servo motor and the end of the second threaded rod. A second synchronous belt is sleeved on the two sets of second synchronous pulleys. A movable frame is threadedly sleeved on the surface of the second threaded rod. The movable frame is slidably mounted on the guide rod on the top surface of the support frame and the feeding frame assembly. Hydraulic rods are fixedly mounted on both ends of the movable frame.

[0011] Furthermore, the conveying assembly includes a suction plate fixedly installed at the bottom of the hydraulic rod. The bottom surface of the suction plate has several sets of through holes, and the top surface of the suction plate is provided with a negative pressure pipe, which is connected to a negative pressure generator.

[0012] The beneficial effects of this utility model are as follows: Multiple substrate boxes are fixed to the feeding frame assembly for stacking and storing substrates. The feeding assembly performs a vertical lifting action. When the top substrate is picked up, the entire stack of substrates in the substrate box assembly is pushed upward. The moving mechanism drives its moving parts to move the hydraulic rod at the end and the conveying assembly to the top of the substrate box assembly. The conveying assembly reliably picks up the single substrate located on the top layer of the substrate box assembly by negative pressure adsorption, realizing efficient, accurate and continuous automated feeding.

[0018] like Figures 1 to 6As shown, the automatic powder feeding mechanism includes a feeding frame assembly 1, on which several sets of material box assemblies 3 are fixedly installed for storing substrates. The feeding frame assembly 1 and the material box assembly 3 are provided with a feeding assembly 4 for vertically lifting the substrates placed in the material box assembly 3. like Figure 2 and Figure 3 As shown, specifically, the feeding assembly 4 includes a first servo motor 401 fixedly installed on the feeding frame assembly 1. A first threaded rod 402 is rotatably inserted into the bottom of the feeding frame assembly 1. A first synchronous wheel 403 is fixedly sleeved on the output end of the first servo motor 401 and the end of the first threaded rod 402. A first synchronous belt 404 is sleeved on the two sets of first synchronous wheels 403. A feeding moving frame 405 is threadedly sleeved on the surface of the first threaded rod 402. The feeding moving frame 405 and the rod on the feeding frame assembly 1 are slidably sleeved. A feeding pusher 406 is fixedly installed on the top surface of the feeding moving frame 405, and a pusher plate 407 is fixedly installed on the top of the feeding pusher 406.

[0019] More specifically, the first servo motor 401 starts the first threaded rod 402 to rotate via two sets of first synchronous pulleys 403 and the first synchronous belt 404 on their surface. The feeding moving frame 405 is threadedly sleeved with the first threaded rod 402, so that the feeding moving frame 405, the feeding pusher 406 and the pusher plate 407 move vertically. The feeding pusher 406 and the pusher plate 407 move the substrates stacked in the material box assembly 3 vertically within the material box assembly 3, and the vertical movement distance of the pusher plate 407 each time is the thickness of a single substrate.

[0020] like Figure 3 and Figure 5 As shown, the bottom surface of the material box assembly 3 is open, the feeding pusher 406 is movably inserted into the opening, and the pusher plate 407 at the top of the feeding pusher 406 is vertically inserted into the material box assembly 3.

[0021] More specifically, the bottom surface of the material box assembly 3 is designed to be open, allowing the feeding pusher 406 to extend from its bottom. The pusher plate 407 is at the top of the feeding pusher 406. The pusher plate 407 rises from the bottom of the material box assembly 3 and directly supports the bottom layer of the entire stack of substrates.

[0022] A moving mechanism 5 is fixedly installed on the feeding frame assembly 1, and hydraulic rods 6 are fixedly installed on both ends of the movable part of the moving mechanism 5. like Figure 1 , Figure 4 and Figure 5As shown, specifically, the moving mechanism 5 includes a support frame 501. The top surface of the support frame 501 and the feeding frame assembly 1 is rotatably connected to a second threaded rod 502 via a bearing seat. A second servo motor 503 is fixedly mounted on the feeding frame assembly 1 via a mounting bracket. A second synchronous pulley 504 is fixedly mounted on the output end of the second servo motor 503 and the end of the second threaded rod 502. A second synchronous belt 505 is sleeved on the two sets of second synchronous pulleys 504. A movable frame 506 is threadedly sleeved on the surface of the second threaded rod 502. The movable frame 506 is slidably mounted on the guide rod on the top surface of the support frame 501 and the feeding frame assembly 1. Hydraulic rods 6 are fixedly mounted on both ends of the movable frame 506.

[0023] More specifically, the second servo motor 503 starts the second threaded rod 502 to rotate via the second synchronous pulley 504 and the second synchronous belt 505. This causes the movable frame 506, which is threaded onto the surface of the second threaded rod 502, to move laterally under the constraint of the support frame 501 and the guide rod on the top surface of the feeding frame assembly 1. This, in turn, drives the conveying assembly 7 to move quickly and precisely laterally above multiple material box assemblies 3 or between different workstations.

[0024] The telescopic end of the hydraulic rod 6 is fixedly connected to the conveying assembly 7 for negative pressure suction of the uppermost base plate of the material box assembly 3; like Figure 5 As shown, specifically, the conveying assembly 7 includes a suction plate 701 fixedly installed at the bottom of the hydraulic rod 6. The bottom surface of the suction plate 701 is provided with several sets of through holes 702, and the top surface of the suction plate 701 is provided with a negative pressure pipe 703, which is connected to a negative pressure generator.

[0025] More specifically, when a substrate needs to be picked up, the negative pressure generator is activated, and a vacuum negative pressure zone is formed at the bottom of the suction plate 701 through the negative pressure pipe 703 and the through hole 702, thereby firmly adsorbing the surface of the substrate. Compared with mechanical grippers, it can better protect the surface of the substrate and prevent scratches.

[0026] like Figure 1 As shown, a material preparation platform assembly 2 is fixedly installed on one side of the feeding frame assembly 1. A photoelectric switch 8 is fixedly installed on the feeding frame assembly 1 via a photoelectric bracket. The photoelectric switch 8 is flush with the top surface of the material box assembly 3.

[0027] More specifically, the photoelectric switch 8 is fixedly installed by a bracket, and its detection height is flush with the top surface of the material box assembly 3. Its function is to detect in real time the remaining height of the substrate inside the material box assembly 3 or whether there is material.

[0028] In summary: Multiple material box assemblies 3 are fixed to the feeding frame assembly 1 for stacking and storing substrates. The feeding assembly 4 performs a vertical lifting action. When the top substrate is picked up, the entire stack of substrates in the material box assembly 3 is pushed upward. The moving mechanism 5 drives its moving parts to move the hydraulic rod 6 at the end and the conveying assembly 7 to directly above the material box assembly 3. The conveying assembly 7 reliably picks up the single substrate located on the top layer of the material box assembly 3 by negative pressure adsorption, realizing efficient, accurate and continuous automated feeding.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
