Description

Technical Field

[0001] The utility model relates to the technical field of relay dust removal, in particular to a dust removal device in the process of manufacturing relays. Background Art

[0002] A relay, also known as an electromagnetic relay, is an electronic control device. It has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] Dust substances are harmful to the electrical contact and magnetic properties of relays, which may cause poor contact or non-conduction of relay contacts, and even make the relay completely ineffective. Therefore, after the relay is assembled, it is often necessary to remove dust from the relay through a dust removal device to ensure the normal use of the relay. In the prior art, generally, the relay is dusted by blowing air, but the relay often needs to be manually turned over during the dust removal process, making the dust removal work more troublesome, and the dust generated during dust removal is difficult to handle immediately, prone to dust flying. Summary of the Utility Model

[0004] The utility model provides a dust removal device in the process of manufacturing relays, which is conducive to conveniently removing dust from the relay and preventing dust flying.

[0005] To solve the problems of the prior art, the utility model discloses a dust removal device in the process of manufacturing relays, including a dust removal frame and a dust removal table, and the dust removal table is arranged inside the dust removal frame.

[0006] A rotating shaft is rotatably connected to the middle end inside the dust removal frame, the dust removal table is fixedly sleeved on the periphery of the rotating shaft, and mounting frames are fixed around the periphery of the dust removal table. An installation groove is opened on one side of the inner wall of the mounting frame, an electric cylinder is fixed in the installation groove, a driving motor is connected to the power end of the electric cylinder, a first clamping plate is connected to the power end of the driving motor, a second clamping plate rotatably connected to the other side of the inner wall of the mounting frame is arranged on the opposite surface of the first clamping plate, and a rotation braking component is arranged outside the rotating shaft.

[0007] An air pump is installed at the top end inside the dust removal frame, and a blowing dust removal component is arranged below the air pump.

[0008] A vacuum cleaner is installed at the bottom end inside the dust removal frame, and a dust suction component is arranged on the vacuum cleaner.

[0009] Furthermore, a plurality of suction cups are connected to the inner sides of the first clamping plate and the second clamping plate.

[0010] Furthermore, the rotation braking assembly includes a braking motor, a PLC controller, a main gear, and a secondary gear. The braking motor and the PLC controller are both fixed to the inner top end of the dust removal frame. The main gear is connected to the power end of the braking motor. The secondary gear is fixedly sleeved around the outer periphery of the rotating shaft, and the secondary gear meshes with the main gear.

[0011] Furthermore, the blowing dust removal assembly includes an air delivery pipe, a concave air outlet pipe, and a plurality of blowing nozzles. The air delivery pipe is communicated with the air outlet of the air pump. The concave air outlet pipe is communicated with the lower end of the air delivery pipe. The blowing nozzles are all obliquely communicated with the inner side of the concave air outlet pipe.

[0012] Furthermore, the dust suction assembly includes a dust inlet pipe, a concave dust suction pipe, and a plurality of dust suction covers. The dust inlet pipe is communicated with the dust suction port of the dust collector. There are two concave dust suction pipes which are respectively fixed to the front and rear ends of the air delivery pipe, and the concave dust suction pipes are both communicated with the dust inlet pipe. The dust suction covers are all communicated with the inner side of the concave dust suction pipe. The concave air outlet pipe is located between the two concave dust suction pipes.

[0013] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0014] 1. By placing the relay in the installation frame and clamping and fixing the relay through the first clamping plate and the second clamping plate, and combining with the operation of the driving motor to drive the relay to rotate, and then through the coordinated operation of the air pump and the blowing nozzles, the blowing nozzles can comprehensively blow dust on the rotating relay, eliminating the need for manual flipping of the relay for dust removal. The dust removal work is not only comprehensive but also convenient to operate.

[0015] 2. Through the coordinated operation of the dust collector and the dust suction covers, and the dust suction covers are located at the front and rear ends of the blowing nozzles. Therefore, when the blowing nozzles blow the dust off the relay, the dust suction covers will immediately absorb the blown dust into the dust collector, avoiding the occurrence of dust flying.

[0016] 3. Through the operation of the rotation driving assembly, the dust removal table and the four installation frames can be driven to rotate. Therefore, it is convenient to replace the relay in the next installation frame for dust removal treatment, which is beneficial to improving the dust removal efficiency of the relay.

Specific implementation manner

[0025] A dust removal device in the process of manufacturing relays:

[0026] As Figures 1-6 shown, in this embodiment, it includes a dust removal frame 1 and a dust removal table 2. The dust removal table 2 is arranged inside the dust removal frame 1. A rotating shaft 4 is rotatably connected to the middle end inside the dust removal frame 1. The dust removal table 2 is fixedly sleeved around the rotating shaft 4. Installation frames 3 are fixedly arranged around the periphery of the dust removal table 2. An installation groove 9 is opened on one side of the inner wall of the installation frame 3. An electric cylinder 10 is fixed inside the installation groove 9. The power end of the electric cylinder 10 is connected to a drive motor 11. The power end of the drive motor 11 is connected to a first clamping plate 12. A second clamping plate 13 rotatably connected to the other side of the inner wall of the installation frame 3 is arranged on the opposite surface of the first clamping plate 12. An air pump 15 is installed at the top end inside the dust removal frame 1. A blowing dust removal assembly is arranged below the air pump 15. The blowing dust removal assembly includes an air delivery pipe 16, a concave air outlet pipe 17 and a plurality of air blowing nozzles 18. The air delivery pipe 16 is communicated with the air outlet of the air pump 15. The concave air outlet pipe 17 is communicated with the lower end of the air delivery pipe 16. The air blowing nozzles 18 are all obliquely communicated with the inner side of the concave air outlet pipe 17. A storage battery 3 is installed at the lower end of the dust removal table 2.

[0027] With the relay placed in the mounting frame 3 and the storage battery 8 set to be electrically connected to the electric cylinder 10 and the drive motor 11, the first clamping plate 12 is driven by the extension of the electric cylinder 10 to approach the relay until the relay is clamped and fixed by the first clamping plate 12 and the second clamping plate 13. Moreover, the relay is clamped and fixed by the first clamping plate 12 and the second clamping plate 13, and the drive motor 11 drives the relay to rotate. When the relay in the leftmost mounting frame 3 is located inside the concave air outlet pipe 17, on the premise that the air pump 15 is started, air is transported into the air delivery pipe 16, the concave air outlet pipe 17 and the air blowing nozzle 18. The air blowing nozzle 18 can comprehensively blow air on the rotating relay for dust removal. Therefore, there is no need for manual flipping of the relay for dust removal. The dust removal work is not only comprehensive but also convenient to operate.

[0028] As Figure 3 shown, in this embodiment, a number of suction cups 14 are connected to the inner sides of the first clamping plate 12 and the second clamping plate 13.

[0029] When the first clamping plate 12 and the second clamping plate 13 clamp the relay, the suction cups 14 will adsorb on the surface of the relay, which is conducive to improving the firmness of clamping the relay by the first clamping plate 12 and the second clamping plate 13 and preventing the relay from accidentally falling during the rotation and dust removal process.

[0030] As Figure 1 、 6 、7 shown, in this embodiment, a dust collector 19 is installed at the inner bottom end of the dust removal frame 1. A dust suction assembly is provided on the dust collector 19. The dust suction assembly includes an air inlet pipe 20, a concave dust suction pipe 21 and a number of dust suction covers 22. The air inlet pipe 20 is communicated with the dust suction port of the dust collector 19. Two concave dust suction pipes 21 are provided and are respectively fixed at the front and rear ends of the air delivery pipe 16, and the concave dust suction pipes 21 are both communicated with the air inlet pipe 20. The dust suction covers 22 are all communicated with the inner sides of the concave dust suction pipes 21. The concave air outlet pipe 17 is located between the two concave dust suction pipes 21.

[0031] When the relay is subjected to air blowing dust removal, the dust collector 19 is started to work at the same time. Since the dust suction covers 22 are located at the front and rear ends of the air blowing nozzle 18, when the air blowing nozzle 18 blows the dust on the relay, the dust suction covers 22 will absorb the blown dust in the first time, and then the dust is sucked into the dust collector 19 through the concave dust suction pipe 21 and the air inlet pipe 20, avoiding the occurrence of dust flying.

[0032] As Figure 1 、 4As shown in the figure, in this embodiment, a rotary braking assembly is provided outside the rotating shaft 4. The rotary braking assembly includes a braking motor 5, a PLC controller 23, a main gear 6 and a sub-gear 7. The braking motor 5 and the PLC controller 23 are both fixed to the inner top end of the dust removal frame 1. The main gear 6 is connected to the power end of the braking motor 5. The sub-gear 7 is fixedly sleeved around the rotating shaft 4, and the sub-gear 7 meshes with the main gear 6.

[0033] When it is necessary to continue dust removal for the next relay, after the dust removal of the previous relay is completed, on the premise that the PLC controller 23 is set to be signal-connected to the braking motor 5, the braking motor 5 is controlled to work through the PLC controller 23. Each time the braking motor 5 drives the main gear 6, the sub-gear 7, the rotating shaft 4, the dust removal table 2 and the mounting frame 3 to rotate 90 degrees and then stop. Therefore, the relay in the next mounting frame 3 can quickly move to the lower part of the concave air outlet pipe 17 and the concave air blowing pipe. The relay that has completed dust removal can be disassembled from the mounting frame 3, and the relay to be dusted subsequently can be installed. In summary, by repeating this process, the dust removal treatment for the next relay can be quickly carried out, effectively improving the dust removal efficiency of the relay.
