Description

Technical Field

[0001] The utility model relates to the technical field of duplexer production and processing, in particular to a glue dispensing tool for a duplexer. Background Art

[0002] The duplexer is the main component of the duplex radio and repeater. Its function is to isolate the transmit and receive signals to ensure that both the receive and transmit signals can work normally at the same time. It is composed of two sets of bandpass filters with different frequencies to prevent the local transmit signal from being transmitted to the receiver.

[0003] The duplexer needs to be glued and potted during the production process, which requires the use of a glue dispenser. After each glue dispensing, glue will remain at the mouth of the glue dispensing tube. When the glue dries, it will affect the use of the glue dispensing tube, so it needs to be cleaned. The traditional way is manual cleaning, and the existing cleaning method is to use mechanical equipment to clean;

[0004] For example, patent application number CN202011377260.2 discloses a dispensing tool appearance cleaning device for processing a duplexer. The patent places a glue gun and its nozzle in a cleaning device 3, and the cleaning liquid in the water guide box 32 drips through the leak hole 415 to rinse the duplexer fixture. After the rinsing is completed, the sponge layer 351 on the inner wall of the block 35 wraps the nozzle, and the block 35 is matched with the cleaning ring 34. The rotation of the rotating shaft 365 drives the block 35 to rotate, and the rotation of the block 35 drives the cleaning ring 34 to rotate. The brush head 341 brushes the side wall, and the sponge layer 351 cleans the glue gun nozzle;

[0005] During use of this patent in the prior art, the nozzle is cleaned by a brush head and a sponge layer, but the defect of this brushing method is that the cleaning liquid in the brushing process will enter the inside of the pipe mouth, and the sponge and the brush head cannot clean out the cleaning liquid (degumming agent), which causes the cleaning liquid (degumming agent) to be mixed with the glue during the dispensing process, which reduces the effect of dispensing, and the cleaning liquid (degumming agent) will melt the glue, causing the problem of inability to fit. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a glue dispensing tool for a duplexer, so as to solve the problem that the method of using cleaning liquid to clean the glue dispensing tube in the prior art described in the background technology will cause the residual cleaning liquid to enter the tube opening of the glue dispensing tube.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: a glue dispensing tool for a duplexer, comprising

[0008] A mounting plate, fixedly connected to the outer wall of the dispensing machine, and provided with a crossbeam plate;

[0009] A lifting frame is liftably arranged on the crossbeam plate;

[0010] A rotating plate is rotatably arranged on the lifting frame;

[0011] A rotating sleeve passes through the rotating plate and is rotatably connected to the rotating plate;

[0012] A plurality of positioning plates are arranged in a ring shape and fixedly connected to the inner wall of the rotating sleeve through a plurality of damping springs, and a side of the positioning plate opposite to the damping spring has a slope surface;

[0013] A plurality of scrapers are respectively fixedly connected to one side of the positioning plate away from the damping spring.

[0014] Preferably: a fixed sleeve is provided with a gear ring on the outer circumferential wall of the rotating sleeve, a servo motor is fixedly connected to the rotating plate, and a gear meshing with the gear ring is fixedly connected to the output end of the servo motor.

[0015] Preferably: a rotating motor is fixedly connected inside the lifting frame, and an output end of the rotating motor is fixedly connected to the rotating plate.

[0016] Preferably: a lifting cylinder is fixedly connected to the crossbeam plate, and an output end of the lifting cylinder is fixedly connected to the lifting frame.

[0017] Preferably, a jet pipe is fixedly connected to the side wall of the lifting frame, and the jet pipe is tilted downward and points to the position of the central axis of the rotating sleeve.

[0018] The beneficial effects of adopting the above technical solution are:

[0019] The present application provides a lifting frame and a rotating plate to drive the rotating sleeve to move, so that the dispensing tube of the dispensing machine can enter the rotating sleeve, and the scraper is close to the dispensing tube, so that the scraper can rotate and move with the rotating sleeve, so that the scraper can clean the outer wall of the dispensing tube, and at the same time the jet pipe can spray gas to blow away the glue scraped off by the scraper.

DETAILED DESCRIPTION

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 In the first embodiment, a glue dispensing tool for a duplexer includes:

[0027] A mounting plate 20, fixedly connected to the outer wall of the dispensing machine 10, and having a crossbeam plate 21 on the mounting plate 20;

[0028] A lifting frame 30 is lifted and disposed on the crossbeam plate 21;

[0029] The rotating plate 40 is rotatably disposed on the lifting frame 30;

[0030] A rotating sleeve 50 passes through the rotating plate 40 and is rotatably connected to the rotating plate 40;

[0031] A plurality of positioning plates 60 are arranged in a ring shape and fixedly connected to the inner wall of the rotating sleeve 50 through a plurality of damping springs 62. The positioning plates 60 have a slope surface 61 on one side opposite to the damping spring 62.

[0032] A plurality of scrapers 70 are respectively fixedly connected to one side of the positioning plate 60 away from the damping spring 62 .

[0033] This embodiment is implemented as follows:

[0034] When the present application is in use, through the vertical movement of the lifting frame 30 on the crossbeam plate 21 and the rotation of the rotating plate 40 on the lifting frame 30, the rotating sleeve 50 can be sleeved on the outer periphery of the glue dispensing tube. When the rotating sleeve 50 continues to move upward, the glue dispensing tube will first contact the slope surface 61 and gradually push the rotating plate 40 and the scraper 70, so that the scraper 70 can move to the outer wall of the glue dispensing tube. At this time, the rotating sleeve 50 can rotate to realize the rotation of the scraper 70, so that the scraper 70 scrapes the glue on the outer wall of the glue dispensing tube.

[0035] The advantage of the present application over the prior art is that it can prevent the cleaning liquid from remaining in the nozzle of the dispensing tube.

[0036] See also Figure 1 , 2 3. A gear ring 51 is fixedly sleeved on the outer circumferential wall of the rotating sleeve 50, a servo motor 53 is fixedly connected to the rotating plate 40, and a gear 52 meshing with the gear ring 51 is fixedly connected to the output end of the servo motor 53;

[0037] The servo motor 53 is provided to drive the gear 52 to rotate, the gear 52 drives the gear ring 51 to rotate, and the gear ring 51 drives the rotating sleeve 50 to rotate on the rotating plate 40 .

[0038] See also Figure 1 , 2 3. A rotating motor 41 is fixedly connected inside the lifting frame 30, and an output end of the rotating motor 41 is fixedly connected to the rotating plate 40;

[0039] The rotating cylinder 41 can drive the rotating plate 40 to rotate on the lifting frame 30 .

[0040] See also Figure 1 , 2 3. A lifting cylinder 31 is fixedly connected to the crossbeam plate 21, and an output end of the lifting cylinder 31 is fixedly connected to the lifting frame 30;

[0041] The lifting frame 30 can be driven to move vertically on the cross beam plate 21 by the lifting cylinder 31 .

[0042] See also Figure 1 , 3 The side wall of the lifting frame 30 is fixedly connected with an air injection pipe 80, and the air injection pipe 80 is tilted downward and points to the position of the central axis of the rotating sleeve 50;

[0043] When the scraper 70 cleans the outer wall of the glue dispensing tube, the air supply device externally connected to the jet tube can blow out gas to blow away the scraped glue.

[0044] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
