Description

Technical Field

[0001] The utility model relates to the technical field of multi-nozzle glue injection heads, in particular to a multi-nozzle glue injection head capable of real-time shielding. Background Art

[0002] Glue filling equipment has become an essential equipment in today's electronic equipment production. In order to improve the efficiency of glue filling, more nozzles are usually designed in the equipment to fill multiple products at the same time.

[0003] When multiple nozzles are used for glue pouring, the number of products does not always fill the pallet. When the last batch of products appears, the pallet cannot be filled, and the number of glue injection heads does not change. This requires some nozzles to shield the glue discharge. The previous solution could only allow glue suction shielding to achieve glue discharge shielding, but this cannot meet the real-time shielding requirement. When the metering device is filled with glue, shielding cannot be achieved. For this reason, we proposed a multi-nozzle glue injection head that can be shielded in real time for efficient glue pouring, automation, and real-time shielding of glue injection. Utility Model Content

The previous solution can only allow glue suction shielding to achieve the shielding of glue discharge, but this cannot meet the real-time shielding. When the metering device is filled with glue, the shielding cannot be achieved. In order to achieve the above purpose, the present utility model provides the following technical solutions: a multi-nozzle glue injection head that can be shielded in real time, including a gantry upper plate, the bottom of the gantry upper plate is fixedly connected to a motor seat, the bottom of the motor seat is fixedly connected to a reducer, one side of the reducer is fixedly connected to a servo motor, the bottom of the gantry upper plate is fixedly connected to a belt one, the internal transmission of the belt one is connected to two synchronous wheels and the two synchronous wheels are symmetrically distributed, the internal transmission of the belt one is connected to a rotating wheel, the bottom transmission of the rotating wheel is connected to a belt two, and the bottom of the belt two is fixedly connected to It is connected to a gantry fixing plate, and a number of sensor blocks are fixedly connected to the bottom of the gantry fixing plate. The specific operation method is that when glue filling is required, the cylinder is retracted, the sensor block is aligned with the piston rod, and the piston rod is lifted after adding material. Then the servo motor drives the glue injection head control board to move, and the piston rod is pressed to perform glue injection. When glue filling is not required at the tail plate, the cylinder of the workstation that does not require glue filling is extended, and the hollow position of the sensor block is aligned with the piston rod, so that when the glue injection head control board is pressed down, the corresponding piston rod will not be pressed, thereby achieving a shielding effect, which is used for efficient glue filling, automation, and real-time shielding of glue injection.

[0005] Further preferably, the sensing blocks are linearly arrayed at the bottom of the gantry fixing plate. One side of each sensing block is fixedly connected to a glue injection head control board. The other side of the glue injection head control board is fixedly connected to a number of air cylinders. One side of the glue injection head control board is fixedly connected to a fixing frame.

[0006] Further preferably, a connecting rod is fixedly connected inside the synchronous pulley. Two lead screws are fixedly connected to the bottom of the gantry upper plate. The lead screws pass through the gantry fixing plate and the movable ends of the lead screws are fixedly connected to the top of the glue injection head control board. The bottom of the air cylinder is fixedly connected to a piston rod. The hollow position of the sensing block is aligned with the piston rod.

[0007] Further preferably, two side baffles are fixedly connected to the bottom of the gantry upper plate. The two side baffles are symmetrically distributed at the bottom of the gantry upper plate. A bottom support is fixedly connected to the opposite sides of the side baffles.

One side of one of the side baffles is connected to the other side of the motor seat. A fixing return frame is fixedly connected to the back of the side baffle. Two L-shaped support plates are fixedly connected to the front of the fixing return frame. A movable column is movably connected to the interior of each of the two L-shaped support plates respectively. One end of the movable column is fixedly connected to a clamping plate. A fixing spring is sleeved on the side surface of the movable column. The two L-shaped support plates are symmetrically distributed on the front of the fixing return frame.

[0010] Compared with the prior art, the beneficial effects of the present utility model are:

[0011] In the present utility model, the specific operation mode is as follows. When glue injection is required, the air cylinder retracts, the sensing block aligns with the piston rod. After feeding materials, the piston rod rises. Then, the glue injection head control board is driven by a servo motor to move, and the piston rod is pressed to perform the glue injection action. When glue injection is not required at the end stage, the air cylinders at the workstations where glue injection is not required extend, aligning the hollow position of the sensing block with the piston rod. Thus, when the glue injection head control board is pressed down, the corresponding piston rod will not be pressed, thereby achieving a shielding effect for efficient glue injection, automation, and real-time shielding of glue injection.

[0012] In the present utility model, when using the multi-nozzle glue injection head that can be shielded in real time, a motor seat is installed on the left side of the upper gantry plate. A speed reducer is installed at the bottom of the motor seat, and a servo motor is installed on the speed reducer. Lead screws are also installed in the middle and on the right side of the upper gantry plate. The lead screws pass through the gantry fixing plate and the moving ends are installed on the glue injection head control board. Synchronous wheels are installed on the lead screws. The motor drives the lead screws to rotate through belt one and belt two, and finally makes the glue injection head control board move up and down. The air cylinder is installed on the glue injection head control board to control the movement of the induction block. During normal glue injection, the air cylinder retracts, and the induction block moves along with the glue injection head control board to press the piston rod to move. When it is necessary to shield the glue injection, the air cylinder extends, and the hollow position of the induction block is aligned with the piston rod, so that the corresponding piston rod does not move without affecting the movement of other piston rods, thereby making the device have high stability and flexibility.
