The water injection well packer sealing performance verification device comprises a separate injection pipe column, the separate injection pipe column comprises an oil pipe, the lower end of the oil pipe is connected with a separate injection tool string, the upper end of the oil pipe is hung on a water injection well opening, and the oil pipe is sequentially connected with a sleeve protection packer and a multi-layer wave code water distribution device. The oil pipe is connected with the electric control valve through the water injection wellhead pipeline, and the electric control valve is installed on the water injection wellhead pipeline to achieve rapid opening and closing actions of the water injection wellhead valve and generate pressure wave signals. The electric control valve is electrically connected with a ground controller; the ground controller is connected with a remote control system; and the surface control device is arranged near a water injection wellhead. The invention further discloses a sealing performance verification method for the packer of the water injection well, the problems that the sealing performance verification experience of an existing packer of the water injection well is dominant and the operation is tedious are solved, the sealing verification procedure is simplified, and the sealing performance verification standardization and automation of the packer of the water injection well are achieved.

The invention belongs to the technical field of LED packaging, and discloses an LED packaging device and method. The dispensing rack is arranged on the conveying mechanism and is used for dispensing the LED; the drying frame is arranged on one side of the dispensing rack, is fixedly connected with the conveying mechanism and is used for curing the dispensed LEDs; the bearing disc is arranged on the conveying mechanism and is used for bearing an LED to be dispensed; and the glue shaking mechanism is arranged below the bearing disc, is fixedly connected with the conveying mechanism and is used for driving the dispensed LEDs on the bearing disc to shake, so that gaps, needing to be encapsulated, of the LEDs are filled with the glue solution. By arranging the glue shaking mechanism, when the LED subjected to glue dispensing is conveyed through the conveying mechanism, the LED subjected to glue dispensing can be shaken, bubbles are reduced, and vacancy is avoided.

The utility model discloses a control system of a hot melt adhesive dispensing device. The hot melt adhesive dispensing device comprises a charging barrel, a liquid box, a heating assembly and a monitoring assembly, a material cavity for loading hot melt adhesive fluid is formed in the charging barrel; the liquid box is installed on the charging barrel and provided with a nozzle and an air pressure valve, a flow channel communicating with the material cavity and the nozzle is formed in the liquid box, and the air pressure valve is used for extruding the hot melt adhesive fluid in the flow channel to the nozzle; the heating assembly comprises a first heating piece which is mounted on the charging barrel and is used for heating the material cavity and a second heating piece which is mounted on the liquid box and is used for heating the runner; the monitoring assembly comprises a first temperature sensor mounted on the charging barrel and used for monitoring the temperature of the material cavity and a second temperature sensor mounted on the liquid box and used for monitoring the temperature of the runner; through cooperative use of the structures, a hot melt adhesive fluid can be kept at a constant temperature in the flowing process, the property change of the hot melt adhesive fluid is avoided, and the adhesive dispensing effect is ensured; the control system comprises the hot melt adhesive dispensing device and a control unit, and has corresponding advantages.

This utility model relates to a needle-type dispensing valve device, including a dispensing valve body and a one-way throttle valve. The dispensing valve body includes a dispensing valve seat, a needle, a piston block, and a spring assembly. The dispensing valve seat has a piston chamber and a glue flow channel. The piston block divides the piston chamber into an upper chamber and a lower chamber. An inlet and outlet are provided on the outer wall of the middle part of the dispensing valve seat. An inlet is provided on the lower part of the dispensing valve seat, and an outlet is provided at the bottom of the dispensing valve seat. Both the inlet and outlet are connected to the glue flow channel. The upper end of the needle extends upward into the lower chamber and connects with the piston block. The lower end of the needle extends downward into the glue flow channel and cooperates with the outlet. The one-way throttle valve has a first valve port and a second valve port. The first valve port is connected to the inlet and outlet, and the second valve port is used to connect to an external air source. The one-way throttle valve can control the flow rate of gas from the first valve port to the second valve port. This pin-type dispensing valve device can prevent water droplets from forming at the end of the dispensing valve, thus improving the dispensing effect.
