DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying Figures 1-4 The present application is further described in detail.

[0032] The embodiments of the present application disclose a vibration feeding device capable of protecting coating.

[0033] Referring to Figure 1 , Figure 2 and Figure 3 , a vibration feeding device capable of protecting coating, comprising a bottom plate 1, a vibration feeding tray 2 for protecting the coating of parts is mounted on the upper surface of the bottom plate 1, the vibration tray of the vibration feeding tray 2 is soft, which improves the protection of the coating of parts, a feeding assembly for continuously feeding parts is arranged on the vibration feeding tray 2, the feeding assembly comprises a storage box 3, a discharge box 4, a stepping motor 5, a rotating shaft 6, a connecting rod 7 and a stop block 8.

[0034] The storage box 3 is arranged above the vibration feeding tray 2 and has a discharge port opened at the bottom end, the discharge box 4 is fixedly connected to the bottom end of the storage box 3 and has an inlet port opened at the top end, the discharge box 4 is in communication with the storage box 3, the stepping motor 5 is fixedly connected to one side wall of the discharge box 4, one end of the rotating shaft 6 is fixedly connected to the output end of the stepping motor 5, the other end of the rotating shaft 6 away from the stepping motor 5 penetrates through the discharge box 4 and forms a rotating connection, the connecting rod 7 is provided with four connecting rods and is fixedly connected to the side wall of the rotating shaft 6 located in the discharge box 4 and forms a ring array, the stop block 8 is provided with four stop blocks and is fixedly connected to the one end of the connecting rod 7 away from the rotating shaft 6, which is used to close the inlet port on the discharge box 4 and prevent continuous feeding of parts.

[0035] Referring to Figure 1 and Figure 2The bottom end of the inside of the vibrating feeding tray 2 is provided with a weighing sensor 9, and one side wall of the discharging box 4 is fixedly connected with a PLC controller 10. The weighing sensor 9 and the stepping motor 5 are electrically connected with the PLC controller 10. Through the weighing sensor 9, the parts on the vibrating feeding tray 2 can be weighed. When the parts are too few and lower than the set value of the weighing sensor 9, a signal is transmitted to the PLC controller 10 to control the stepping motor 5 to start, so that the stepping motor 5 continuously rotates by an angle to put the parts on the vibrating feeding tray 2. When the weighing sensor 9 is higher than the set value, the PLC controller 10 sends a stop signal to the stepping motor 5, so that the stepping motor 5 stops after completing the angle rotation, and the parts are accurately put.

[0036] With reference to Figure 3 The top end of the inside of the discharging box 4 is fixedly connected with an elastic rubber pipe 11 below the discharging port of the storage box 3. The side wall of the side of the stop block 8 away from the connecting rod 7 is fixedly connected with an elastic rubber pad 12. When the stop block 8 blocks the parts in the storage box 3, the elastic rubber pipe 11 and the elastic rubber pad 12 can reduce the clamping force when some parts are clamped between the stop block 8 and the side wall of the discharging box 4, preventing damage to the parts.

[0037] With reference to Figure 1 The bottom end of the inside of the storage box 3 is inclined and lower near the discharging port of the storage box 3, and higher away from the discharging port of the storage box 3, so that the parts are concentrated at the discharging port of the storage box 3, facilitating the falling of the parts.

[0038] With reference to Figure 1 and Figure 2 One side of the upper surface of the bottom plate 1 is fixedly connected with an electric telescopic rod 13, and the output end of the electric telescopic rod 13 is fixedly connected with one side wall of the storage box 3. The electric telescopic rod 13 is electrically connected with the PLC controller 10. When the stepping motor 5 starts, the electric telescopic rod 13 is controlled to retract by the PLC controller 10, which can drive the storage box 3 to move downward, so that the discharging box 4 approaches the vibrating feeding tray 2, reduces the impact force of the falling parts, and improves the protection of the parts. When the stepping motor 5 stops, the electric telescopic rod 13 drives the storage box 3 to rise away from the vibrating feeding tray 2, preventing the vibrating feeding tray 2 from being affected.

[0039] With reference to Figure 1 The other side of the upper surface of the bottom plate 1 is fixedly connected with a limiting rod 14, and one side wall of the storage box 3 away from the electric telescopic rod 13 is fixedly connected with a limiting block 15. One end of the limiting rod 14 away from the bottom plate 1 penetrates through the limiting block 15 and is fixedly connected with a limiting disc 16. The limiting rod 14 and the limiting block 15 can improve the stability of the storage box 3 when it is lifted, preventing the storage box 3 from shaking.

[0040] With reference to Figure 2The top end of the storage box 3 is hinged with a sealing cover 17, and the storage box 3 can be closed through the sealing cover 17 to prevent dust from falling in.

[0041] With reference to Figure 4 The spiral track of the vibration feeding disc 2 is provided as an inclined surface, so as to improve the stability of the vibration feeding disc 2 when conveying parts.

[0042] The implementation principle of the vibration feeding device capable of protecting the coating is as follows: in use, the user first adds parts into the storage box 3 for storage, and then the parts on the vibration feeding disc 2 are weighed through the weighing sensor 9; when the parts are too few and lower than the set value of the weighing sensor 9, a signal is transmitted to the plc controller 10 to control the stepping motor 5 to start, so that the stepping motor 5 continuously rotates by 90 degrees, and the four stop blocks 8 are moved to the lower side of the storage box 3 in turn to block the discharge port, so that the parts in the storage box 3 fall from the discharge port into the vibration feeding disc 2 in the alternating process of the stop blocks 8 to add the parts; when the weighing sensor 9 is higher than the set value, the plc controller 10 sends a stop signal to the stepping motor 5, so that the stepping motor 5 stops after completing the angle rotation, so as to realize precise feeding and prevent too much or too little feeding; at the same time, when the stepping motor 5 starts, the electric telescopic rod 13 can be controlled to retract through the plc controller 10, so as to drive the storage box 3 to move downward, so that the discharge box 4 is close to the vibration feeding disc 2 to reduce the impact force of the parts falling and improve the protection of the parts; when the stepping motor 5 stops, the electric telescopic rod 13 drives the storage box 3 to move upward and away from the vibration feeding disc 2 to prevent affecting the operation of the vibration feeding disc 2, so as to avoid the problem that the parts in the vibration hopper cannot be continuously added, which reduces the work efficiency.

[0043] The above are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
