Description

Technical Field

[0001] This utility model relates to the field of PCBA board dispensing technology, specifically a fully automatic PCBA board dispensing equipment. Background Technology

[0002] Glue application can firmly fix electronic components to the PCBA board, preventing components from loosening or falling off due to vibration or other reasons during transportation and use. Glue application on PCBA boards is to protect the circuit board and its components from environmental influences and improve their reliability and stability.

[0003] The prior art discloses patent application number "CN202220150641.5", which discloses a precision dispensing device for PCBA board processing.

[0029] The lower side of the rotating base 10 is fixedly equipped with the dispensing equipment body 11. The dispensing equipment model is ZYDJ-441RR. The dispensing equipment uses compressed air as a power source to send compressed air into the glue bottle. Under the action of compressed air, the glue is forced into the feed tube connected to the piston chamber. When the piston is in the upward stroke, the piston chamber is full of glue. When the piston pushes the dispensing needle downward, the glue is pressured and squeezed out from the needle nozzle to perform dispensing work on the PCBA board. It has the ability to automate. The lower side of the fixed plate 9 is fixedly installed with an L-shaped support plate 17. A threaded shaft 18 is rotatably connected to the upper side of the 7. A second mounting seat 20 is threadedly connected to the outer surface of the threaded shaft 18. A first mounting seat 19 is connected to the rear side of the rotating seat 10. A movable plate 21 is rotatably connected between the first mounting seat 19 and the second mounting seat 20. Two first round rods 25 are connected between the fixed plate 9 and the L-shaped support plate 17. By setting the first round rods 25, the movement trajectory of the second mounting seat 20 can be restricted, allowing the second mounting seat 20 to move up and down smoothly in order to adjust the dispensing angle of the dispensing equipment.

[0030] The equipment base 1 is internally connected to a threaded rotating rod 3. The outer surface of the threaded rotating rod 3 is threadedly connected to a connecting plate 4. A base plate 5 is fixedly mounted on the upper side of the connecting plate 4. Two symmetrically arranged clamping plates 27 are snapped onto the rear side of the base plate 5. A tooling plate 28 is installed between the two clamping plates 27. Through the installation and use of the clamping plates 27 and the tooling plate 28, the two clamping plates 27 can be used to position the tooling plate 28 and ensure the stability of the PCBA board on the tooling plate 28. The tooling plate 28 is internally fixedly connected to a first smooth rod 33 and a second smooth rod 36. The outer surface of the first smooth rod 33 is slidably connected to two first rubber clamps 34 for fixing the PCBA board. A second spring 35 is connected between the two first rubber clamps 34. The outer surface of the second smooth rod 36 is slidably connected to two second rubber clamps 37 for fixing the PCBA board. A third spring 38 is connected between the two second rubber clamps 37.

[0031] The rear side of the threaded rotating rod 3 passes through the equipment base 1 and extends to the rear side of the equipment base 1. A second servo motor 29 is fixedly installed on the rear side of the threaded rotating rod 3 via a motor mounting. A groove 30 is opened on the rear side of the tooling plate 28. Two symmetrically arranged U-shaped handles 32 are installed on the upper side of the base plate 5. The two U-shaped handles 32 can be used to easily remove all the PCBA boards on the tooling plate 28, saving time and effort and making it convenient to use. Two second round rods 31 are connected inside the equipment base 1. The outer surfaces of the two second round rods 31 are slidably connected to the inside of the connecting plate 4. By setting the second round rods 31, the movement trajectory of the connecting plate 4 can be restricted, allowing the connecting plate 4 to drive the base plate 5 to move stably and transport the PCBA boards.

[0032] Both ends of the rotating seat 10 are fixedly installed with L-shaped side plates 13, and both ends of the dispensing equipment body 11 are connected with round seats 12. One side of each of the two L-shaped side plates 13 is slidably connected with a clamping rod 14 for fixing the dispensing equipment body 11. One side of the clamping rod 14 passes through the L-shaped side plate 13 and extends to the other side of the L-shaped side plate 13. A first spring 15 is connected between each of the two clamping rods 14 and the L-shaped side plate 13.

[0033] A top plate 23 is fixedly provided on the upper side of the dispensing equipment body 11. A fixing block 22 for fixing the top plate 23 is connected to the front side of the rotating seat 10. A positioning post 24 for fixing the top plate 23 is snapped into the front side of the top plate 23.

[0034] Each of the two round seats 12 has a positioning groove 16 on one side. The positioning groove 16 is adapted to the clamping rod 14. The outer surface of the clamping rod 14 is engaged with one side of the round seat 12 through the positioning groove 16.

[0035] The upper side of the threaded shaft 18 passes through the fixing plate 9 and extends to the upper side of the fixing plate 9. The upper side of the threaded shaft 18 is fixedly connected to the No. 1 servo motor 26 through the motor mounting plate. The outer surfaces of the two first round rods 25 are slidably connected to the interior of the second mounting base 20.

[0036] The working principle of the fully automatic dispensing equipment for PCBA boards provided by this utility model is as follows:

[0037] By driving the output shaft of the first servo motor 26 to rotate the threaded shaft 18, the second mounting seat 20 on the threaded shaft 18 can move upward. This drives the movable plate 21 to rotate upward, causing the dispensing equipment body 11 at the rotating seat 10 to rotate forward, so as to adjust the dispensing angle of the dispensing equipment. Conversely, when the second mounting seat 20 rotates downward, the dispensing equipment body 11 can rotate backward, thereby further adjusting the dispensing angle of the dispensing equipment. This allows the dispensing equipment to flexibly adjust the dispensing angle according to the dispensing situation, improving the flexibility of the fully automatic PCBA board dispensing equipment. Then, the motor of the electric slide table 6 can drive the electric slider 7 to move the dispensing equipment body 11 left and right to adjust, so as to perform dispensing work on PCBA boards at different positions, improving the working efficiency of the fully automatic PCBA board dispensing equipment. At the same time, the electric push rod 8 can also drive the dispensing equipment to move above the PCBA board to realize fully automatic dispensing processing.

[0038] By placing the PCBA board into two first rubber clamps 34 equipped with second springs 35 and two second rubber clamps 37 equipped with third springs 38, the elastic force of the second springs 35 and third springs 38 allows the two sets of rubber clamps to elastically hold the PCBA board, preventing damage and improving the safety of the dispensing process. Then, the output shaft of the second servo motor 29 drives the threaded rotating rod 3 to rotate, allowing the connecting plate 4 on the threaded rotating rod 3 to move the base plate 5 forward. This allows the PCBA board on the tooling plate 28 to... The plate can be moved sequentially to the bottom of the dispensing equipment body 11 to continuously perform dispensing work. Then, the two clamping rods 14, each equipped with a first spring 15, are used to clamp the plate into the two round seats 12 on the dispensing equipment body 11 for initial locking and fixing. The top plate 23 on the dispensing equipment body 11 is then locked into the inside of the fixing block 22. The positioning post 24 is then inserted into the fixing block 22 and the top plate 23 to further position the dispensing equipment body 11. This facilitates flexible loading, unloading, and maintenance of the dispensing equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
