Description

Technical Field

[0001] The utility model belongs to the technical field of PCB drill bit production and relates to a feeding device for a PCB drill bit shank forming press. Background Art

[0002] PCB, also known as printed circuit board, is an important electronic component. It is the support for electronic components and the carrier for electrical connections of electronic components. Because it is made using electronic printing technology, it is called a printed circuit board. In the PCB processing process, PCB drills are needed to open holes in the board to facilitate circuit design, so PCB drills have been widely used.

[0003] In the production process of PCB drill bits, a forming press is required to press powder into rods. By moving the material cover that is inverted on the forming press table, the powder in the material cover is filled into the mold hole to achieve the effect of automatic feeding. However, a feeding funnel is connected above the material cover. The operator needs to climb a ladder to manually pour the powder into the funnel at a higher position, which is inconvenient and unsafe to use.

[0004] Based on this, we designed a loading device for a PCB drill bit shank forming press. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and propose a feeding device for a PCB drill bit shank forming press. The technical problem to be solved by the device is: how to add powder to the PCB drill bit shank forming press at a lower position to facilitate operation and improve safety.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A feeding device for a PCB drill bit shank forming press comprises a suction pipe and a material hopper fixed to the side of the forming press, and a material cover arranged on the forming press table, wherein the suction pipe is inserted into the bottom of the material hopper, and a pushing mechanism for pushing the material cover to move is provided on the forming press table, the material cover is connected to a bent pipe, and the upper end of the bent pipe is arranged horizontally, the upper end of the suction pipe is located inside the bent pipe and parallel to the bent pipe, an expansion piece is fixed on the outside of the suction pipe, and a sealing ring is fixed on the outside of the expansion piece, the sealing ring is abutted against the inside of the bent pipe, the end of the suction pipe located on the inside of the bent pipe is connected to an end cover via a self-resetting rotating shaft, a fixing piece is fixed inside the bent pipe, and a baffle is connected below the fixing piece via another self-resetting rotating shaft, an air outlet pipe is connected to the side wall of the bent pipe, and the air outlet pipe is located below the fixing piece.

[0008] The pushing mechanism includes a horizontal plate fixed on the material cover and a fixed plate fixed on the forming press table. Two symmetrically distributed sliding holes are opened on the fixed plate. Two guide rods are fixed on the horizontal plate, and the guide rods pass through the sliding holes at corresponding positions. A push rod motor is fixed on the fixed plate, and the output end of the push rod motor is fixedly connected to the horizontal plate.

[0009] With the above structure, when in use, the push rod motor drives the material cover to move back and forth, pushing the material cover forward and covering the mold hole, adding the powder in the material cover into the mold hole, and then pulling the material cover back. In addition, during the movement of the material cover, the guide rod can limit the moving direction of the material cover and improve stability.

[0010] The bent pipe is made of transparent material, and the lower end of the suction pipe is connected with a hose, which is inserted into the bottom of the material hopper.

[0011] With the above structure, the operator can observe the amount of material inside through the transparent bent pipe. When there is a lot of material, the hose can be pulled out of the material hopper to prevent congestion and blockage, thereby improving the operating stability of the device.

[0012] A rubber ring is fixed to the bottom edge of the material cover, and the rubber ring abuts against the table of the forming press.

[0013] With the above structure, when the material cover drives the powder to move, the rubber ring can prevent the powder from remaining on the table, thereby improving the cleanliness of the table and reducing powder waste.

[0014] A filter is fixed at the bottom of the air outlet pipe.

[0015] With the above structure, when in use, the powder sliding down the wall of the elbow may be lifted up. At this time, the filter can prevent the dust from being discharged with the air, reducing powder waste and protecting the surrounding environment.

[0016] Compared with the existing technology, the PCB drill bit shank forming press feeding device has the following advantages:

[0017] 1. Through the elbow, suction pipe, end cover and baffle, the powder in the material hopper can be sucked into the elbow while the material cover moves back and forth, so as to realize continuous feeding of the material cover. There is no need to use additional feeding equipment, nor does the operator need to carry the powder upward. The operator only needs to pour the material into the lower material hopper, which is simpler and safer to operate.

[0018] 2. Through the bend and hose, the transparent bend can show the amount of material inside it. When there is a lot of material, the hose can be pulled out of the material hopper to prevent material congestion and blockage, which can improve the operating stability of the device.

[0019] 3. The material cover is driven to move back and forth by the pushing mechanism and the rubber ring. During the movement, the guide rod can improve the movement stability and cooperate with the rubber ring to improve the sealing between the material cover and the forming press table, preventing powder from remaining on the table, improving the cleanliness of the table and reducing powder waste.
