Description

Technical Field

[0001] The utility model relates to the technical field of PCBA board processing, in particular to a glue dispensing device for PCBA board processing. Background Art

[0002] Circuit board dispensing is the process of applying a layer of glue or sealant on the circuit board to fix and protect electronic components. Dispensing can make the circuit board waterproof and dustproof, and improve the durability and stability of electronic products. Now it is usually necessary to place the circuit board on the support plate of the dispensing machine before dispensing.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when using a dispensing machine to dispense glue on a circuit board, the circuit board is simply placed on the support plate of the dispensing machine, which makes it easy for the circuit board to shift during the dispensing process, causing the staff to re-dispense glue, thereby reducing work efficiency.

[0004] Therefore, the utility model provides a glue dispensing device for PCBA board processing. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dispensing device for PCBA board processing, including a dispensing machine, a support plate is fixedly installed on the surface of the dispensing machine, and a limiting structure is provided on the surface of the support plate. The limiting structure includes two fixing frames, and the surfaces of the two fixing frames are fixedly connected to the support plate. Two supporting pins are slidably connected inside the two fixing frames, and a connecting plate is fixedly installed on the surface of the support pin. The surface of the support pin is slidably sleeved with a resist plate, and the internal thread of the connecting plate is connected with a latch, and the surface of the latch is in contact with the resist plate. The surface of the support pin is slidably sleeved with two square plates, and the surface of the square plate is fixedly installed with a protective pad, and the surface of the protective pad is slidably connected to the support plate.

[0007] The effect achieved by the above components is: by setting the limiting structure, the circuit board can be limited when the dispensing machine is dispensing glue on the circuit board, so that the circuit board will not deviate during the dispensing process, thereby improving the dispensing efficiency.

[0008] Preferably, the surfaces of the two support pins are sleeved with springs, and the two ends of the springs are fixedly connected to the connecting plate and the abutment plate respectively.

[0009] The effect achieved by the above components is that the abutment plate can move toward the direction close to the fixing frame under the action of the spring elastic force, thereby achieving the effect of assisting the movement of the abutment plate.

[0010] Preferably, the surfaces of the two support pins are sleeved with two bearing frames, the surfaces of the bearing frames are rotatably connected with circular plates, and the surfaces of the two fixing frames are provided with circular plates, and the surfaces of the circular plates are slidably connected with the inner walls of the limiting grooves.

[0011] The effect achieved by the above components is that the support pin can slide under the support of the circular plate.

[0012] Preferably, a shielding structure is provided on the surface of the dispensing machine, and the shielding structure includes two supporting plates, the surfaces of the two supporting plates are fixedly connected to the dispensing machine, and mounting rods are rotatably inserted inside the two supporting plates. A shielding cloth is fixedly installed on the arc surface of the mounting rod, and a positioning rod is fixedly installed on the end of the shielding cloth away from the mounting rod.

[0013] The effect achieved by the above components is: by setting the shielding structure, the support plate of the glue dispensing machine can be shielded when the glue dispensing machine is not in use, so that dust will not fall on the support plate of the glue dispensing machine, thereby ensuring the cleanliness of the glue dispensing machine.

[0014] Preferably, contact plates are fixedly mounted on both ends of the positioning rod, and the internal threads of the contact plates are connected with a bayonet, and the surface of the bayonet is in contact with the glue dispensing machine.

[0015] The effects achieved by the above components are: the latch, the contact plate and the positioning rod can limit the shielding cloth so that the shielding cloth will not fall off the dispensing machine.

[0016] Preferably, the arc surface of the mounting rod is threadedly connected to two cylinders, and the surfaces of the cylinders are in contact with the bearing plate.

[0017] The effect achieved by the above components is: when the cylinder is rotated, the cylinder moves toward the direction close to the bearing plate with the help of the thread. After the cylinder moves a certain distance, the surface of the cylinder squeezes the bearing plate. At this time, the bearing plate and the mounting rod are fixed, achieving the effect of fixing the bearing plate and the mounting rod.

[0018] In summary:

In the utility model, when it is necessary to dispense glue on the circuit board, first put the circuit board on the supporting plate, then slide the supporting pin, and the supporting pin slides in the direction close to the circuit board. The supporting pin slides under the support of the circular plate and the carrier, and the supporting pin drives the square plate to slide while sliding, and the square plate drives the protective pad to slide while sliding. After the protective pad slides a certain distance, the surface of the protective pad contacts the circuit board. Then, the pin on the connecting plate is rotated, and the pin moves in the direction close to the fixing frame with the help of the thread. After the pin moves a certain distance, the surface of the pin squeezes the push plate. After the push plate is squeezed, the push plate will squeeze the fixing frame. At this time, the supporting pin and the fixing frame are fixed, and the circuit board is also limited on the supporting plate. At this time, the circuit board can be dispensed with glue. By setting a limiting structure, the circuit board can be limited when the glue dispensing machine dispenses glue on the circuit board, so that the circuit board will not deviate during the glue dispensing process, thereby improving the glue dispensing efficiency.

[0020] 2. In the utility model, when the glue dispensing machine is not used to dispense glue on the circuit board, the positioning rod is first pulled, and the movement of the positioning rod drives the shielding cloth to move, and the support plate of the glue dispensing machine is shielded by the shielding cloth, and then the pin is inserted into the two contact plates. At this time, the pin can limit the positioning rod on the glue dispensing machine with the help of the contact plate, and the shielding cloth is also limited on the glue dispensing machine. At this time, the shielding cloth can block dust. By setting a shielding structure, the support plate of the glue dispensing machine can be shielded when the glue dispensing machine is not in use, so that dust will not fall on the support plate of the glue dispensing machine, thereby ensuring the cleanliness of the glue dispensing machine.
