[0024] By adopting the above technical scheme, the lifting ring is convenient for taking the top plate 212, the guide rod 23 can slide in the bracket 4, and welding fixation makes the guide rod 23 and the moving frame 21 more firm.

[0025] When the embodiment is used, the circuit board to be glued is placed between the two clamping plates 10 of the placing plate 12, the motor one 15 is started to drive the bidirectional screw rod 11 to rotate, the two clamping plates 10 are moved towards each other due to the opposite screw directions of the two clamping plates 10 and the bidirectional screw rod 11, and the circuit board is stably clamped and fixed.

[0026] After clamping is completed, the electric push rod two 22 is started to push the moving frame 21 to translate towards the circuit board, the motor two 24 is started at the same time to drive the brush roller 25 to rotate at high speed, the surface of the circuit board to be coated is swept and cleaned by the rotation of the brush roller 25, after cleaning work is completed, the electric push rod one 7 is started to push the lifting plate 8 and the glue gun 9 to move downwards to a preset gluing height, the glue gun 9 is started at the same time and performs dispensing work on the circuit board.

[0030] The difference between this embodiment and embodiment 1 is that the material receiving assembly 3 comprises a motor three 32, the motor three 32 is fixedly installed on one side of the upper end of the lifting plate 8, the output end of the motor three 32 is coaxially and fixedly provided with an electric push rod three 33, the output end of the electric push rod three 33 is fixedly connected with a rotating plate 31, one side of the upper end of the rotating plate 31 is clamped with a material receiving box 34, and a groove 38 matched with the material receiving box 34 is formed in the upper end of the rotating plate 31.

[0031] By adopting the technical scheme, after the glue gun 9 completes the glue dropping operation, the electric push rod three 33 is started to push the rotating plate 31 to move downward to a preset position, the motor three 32 is started to drive the electric push rod three 33 to drive the rotating plate 31 to rotate, until the receiving box 34 at the upper end of the rotating plate 31 is accurately rotated to be directly below the glue outlet of the glue gun 9, the residual glue liquid at the glue outlet of the glue gun 9 can be directly dropped into the receiving box 34 to complete collection, the setting of the receiving assembly 3 can effectively intercept the residual glue that is unexpectedly dropped by the glue gun 9, avoid the residual glue from polluting the non-coating area of the circuit board and the surface of the device workbench 1, and reduce the equipment cleaning and maintenance cost.

[0032] Further in the application, the receiving assembly 3 further comprises a telescopic rod 35, the telescopic rod 35 is fixedly installed at the center of the electric push rod three 33 at the upper end of the rotating plate 31, the upper end of the telescopic rod 35 is fixedly connected with a sliding block 36, and an arc-shaped groove 37 that is matched with the sliding block 36 is formed in the inner portion of the lifting plate 8.

[0033] By adopting the technical scheme, in the process that the rotating plate 31 is lifted and lowered along with the electric push rod three 33, the telescopic rod 35 synchronously performs telescopic movement to adapt to the displacement change of the rotating plate 31, when the rotating plate 31 rotates around the electric push rod three 33, the sliding block 36 at the upper end of the telescopic rod 35 slides along the arc-shaped groove 37 in the inner portion of the lifting plate 8, and the combined structure of the telescopic rod 35 and the sliding block 36 can stably support and limit the side of the rotating plate 31 that is away from the electric push rod three 33, so as to avoid damage of the connection between the rotating plate 31 and the electric push rod three 33 due to stress concentration, and improve the structural stability in the rotating process of the rotating plate 31.

[0034] Further in the application, the receiving assembly 3 further comprises an annular magnetic strip one 39, the annular magnetic strip one 39 is fixedly arranged at the lower end of the receiving box 34, and an annular magnetic strip two 310 is fixedly arranged at a position corresponding to the annular magnetic strip one 39 in the inner portion of the groove 38.

[0035] By adopting the technical scheme, when the receiving box 34 is clamped into the groove 38 at the upper end of the rotating plate 31, the annular magnetic strip one 39 at the lower end of the receiving box 34 and the annular magnetic strip two 310 in the inner portion of the groove 38 are mutually adsorbed, the rapid fixing of the receiving box 34 is realized through the magnetic attraction force, the displacement and shaking of the receiving box 34 in the rotating or lifting process of the rotating plate 31 is effectively prevented, and the reliability of the residual glue collection operation is ensured.

[0036] Further in the application, lifting grooves are formed at the upper sides of both ends of the receiving box 34, and the telescopic rod 35 and the rotating plate 31 and the telescopic rod 35 and the sliding block 36 are fixedly connected in a welding manner.

[0037] By adopting the technical scheme, the setting of the lifting grooves facilitates the carrying of the receiving box 34, and the welding fixing makes the telescopic rod 35 and the rotating plate 31 and the telescopic rod 35 and the sliding block 36 more firm.

[0038] In this embodiment, after the glue gun 9 completes the dispensing operation, the electric push rod 33 is activated to push the rotating plate 31 downward to the preset position. Then, the motor 32 is activated to drive the electric push rod 33 to rotate the rotating plate 31 until the receiving box 34 at the top of the rotating plate 31 is precisely rotated to directly below the glue gun 9's dispensing nozzle. The glue residue at the glue gun 9's dispensing nozzle can drip directly into the receiving box 34 for collection. The receiving component 3 can effectively intercept the glue residue that drips unexpectedly from the glue gun 9, preventing the glue residue from contaminating the non-coated areas of the circuit board and the workbench 1 of the device, thus reducing the equipment cleaning and maintenance costs.

[0039] During the process of the rotating plate 31 rising and falling with the electric push rod 33, the telescopic rod 35 moves synchronously to adapt to the displacement changes of the rotating plate 31. When the rotating plate 31 rotates around the electric push rod 33, the slider 36 at the upper end of the telescopic rod 35 slides along the arc groove 37 inside the lifting plate 8. The combined structure of the telescopic rod 35 and the slider 36 can provide stable support and limit the side of the rotating plate 31 away from the electric push rod 33, avoid damage to the connection between the rotating plate 31 and the electric push rod 33 due to force concentration, and improve the structural stability of the rotating plate 31 during rotation.

[0040] When the receiving box 34 is inserted into the groove 38 at the upper end of the rotating plate 31, the annular magnetic strip 39 at the lower end of the receiving box 34 and the annular magnetic strip 310 inside the groove 38 attract each other. The magnetic attraction force quickly fixes the receiving box 34, effectively preventing the receiving box 34 from shifting or shaking during the rotation or lifting of the rotating plate 31, and ensuring the reliability of the residual glue collection operation.

[0041] The working principle and usage process of this invention: When using the circuit board gluing device, install the device in a suitable position, place the circuit board to be glued between the two clamping plates 10 of the placement plate 12, start the motor 15 to drive the bidirectional lead screw 11 to rotate. Since the threads of the two clamping plates 10 and the bidirectional lead screw 11 are opposite, the bidirectional lead screw 11 can drive the two clamping plates 10 to move towards each other, thereby achieving stable clamping and fixing of the circuit board.

[0042] After clamping is completed, start the electric push rod 22 to push the moving frame 21 to move horizontally towards the circuit board. Simultaneously start the motor 24 to drive the brush roller 25 to rotate at high speed. Use the rotation of the brush roller 25 to sweep and clean the surface of the circuit board to be coated. After the cleaning operation is completed, start the electric push rod 7 to push the lifting plate 8 and glue gun 9 to move downward to the preset glue application height. The glue gun 9 then starts and performs glue application on the circuit board.

[0043] During the glue application process, linear module 2 6 can drive slide 2 5 to move laterally along the support 4, thereby driving glue gun 9 to complete the lateral glue application action. Linear module 1 13 can drive slide 1 14 to move longitudinally along the worktable 1, thereby driving the circuit board on the placement plate 12 to complete the longitudinal displacement. Through the coordinated movement of linear module 1 13 and linear module 2 6, glue gun 9 can achieve full coverage glue application in a two-dimensional plane, effectively expanding the glue application range of the device. The above-mentioned cleaning component 2 can thoroughly remove dust and impurities from the surface of the circuit board before glue application, avoiding the impact of impurity residue on the adhesion performance between the glue layer and the circuit board, and ensuring the subsequent glue dispensing quality.

[0044] While the brush roller 25 is cleaning the circuit board, the suction fan 27 is activated. The suction fan 27 creates a negative pressure environment inside the fixed tube 29 through the filter box 26 and the connecting pipe 210. Several suction heads 211 near the end of the fixed tube 29 close to the brush roller 25 then generate suction force, sucking the dust and impurities swept off by the brush roller 25 into the fixed tube 29 and transporting them to the filter box 26 through the connecting pipe 210. The impurities pass through several filter screens 28 in the filter box 26 for multi-stage filtration, achieving efficient separation of dust and airflow. The combined design of the suction heads 211 and the filter box 26 can collect and adsorb the dust generated during the cleaning process in real time, preventing dust from falling back onto the circuit board surface and significantly improving the cleaning effect of the circuit board.

[0045] When the filter screen 28 needs to be cleaned or replaced, unscrew the bolts used to fix the top plate 212, and the top plate 212 can be removed from the top of the filter box 26. At this time, the filter screen 28 can be quickly taken out along the slot 213 inside the filter box 26. This structural design makes it easy for operators to disassemble and maintain the filter screen 28, ensuring the long-term stable operation of the dust removal system.

[0046] After the glue gun 9 completes the dispensing operation, the electric push rod 33 is activated to push the rotating plate 31 downward to the preset position. Then, the motor 32 is activated to drive the electric push rod 33 to rotate the rotating plate 31 until the receiving box 34 at the top of the rotating plate 31 is precisely rotated to directly below the glue gun 9's dispensing nozzle. The glue residue at the glue gun 9's dispensing nozzle can drip directly into the receiving box 34 for collection. The receiving component 3 can effectively intercept the glue residue that drips unexpectedly from the glue gun 9, preventing the residue from contaminating the non-coated areas of the circuit board and the workbench 1 of the device, thus reducing the equipment's cleaning and maintenance costs.

[0047] During the process of the rotating plate 31 rising and falling with the electric push rod 33, the telescopic rod 35 moves synchronously to adapt to the displacement changes of the rotating plate 31. When the rotating plate 31 rotates around the electric push rod 33, the slider 36 at the upper end of the telescopic rod 35 slides along the arc groove 37 inside the lifting plate 8. The combined structure of the telescopic rod 35 and the slider 36 can provide stable support and limit the side of the rotating plate 31 away from the electric push rod 33, avoid damage to the connection between the rotating plate 31 and the electric push rod 33 due to force concentration, and improve the structural stability of the rotating plate 31 during rotation.

[0048] When the receiving box 34 is inserted into the groove 38 at the upper end of the rotating plate 31, the annular magnetic strip 39 at the lower end of the receiving box 34 and the annular magnetic strip 310 inside the groove 38 attract each other. The magnetic attraction force quickly fixes the receiving box 34, effectively preventing the receiving box 34 from shifting or shaking during the rotation or lifting of the rotating plate 31, and ensuring the reliability of the residual glue collection operation.
