[0003] At present, the glue injection dispensers on the market are generally assembled with an upper cover and a shell, and the two are fastened together. However, due to the existence of injection molding or incomplete assembly, there will be a gap between the upper cover and the shell. In this way, glue leakage often occurs during high-speed centrifugal glue injection. This glue leakage phenomenon will cause uneven glue amounts at both ends of the dialyzer, or cause glue contamination on the surface of the dialyzer product; and the upper cover is easy to fall off the shell during the automatic assembly and disassembly of the dispenser.

DETAILED DESCRIPTION

[0021] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, the dispenser provided by the utility model is mainly composed of an upper cover 110 and a shell 120, and the upper cover 110 is buckled on the top of the shell 120; the air claws of the dispenser grabbing mechanism 3 clamp the dispenser at the transmission line A and insert it into the interface 210 of the dialyzer 2 in the tray at the transmission line B. Each tray is loaded with two dialyzers, and the dialyzers are placed in an up and down cross-shaped manner at different angles.

[0023] like Figure 3 and Figure 4 As shown, the upper cover 110 is mainly composed of an upper cover plate 112, a glue injection port 111, a snap plate 113, a positioning groove 114, a glue baffle plate 115 and a reinforcing rib 116. The dialyzer 2 with the dispenser 1 installed is transferred to the centrifugal sealing process. The motor drives the turntable to rotate centrifugally at high speed. The glue injection nozzle of the glue injection machine extends into the glue injection port 111 of the dispenser 1, and the polyurethane glue is "thrown" to both ends of the dialyzer 2 shell to achieve sealing, and the air claw of the dispenser grabbing mechanism 3 clamps the inner diameter of the glue injection port 111 to achieve assembly and disassembly between the dispenser 1 and the dialyzer 2. The positioning groove 114 of the outer ring can buckle the upper cover 110 on the shell 120, and the four sets of snap plates 113 can fix the upper cover 110 on the shell 120. During the glue injection process, the extended glue baffle plate 115 can seal the polyurethane glue in the shell 120 to prevent leakage. The reinforcing rib 116 can make the upper cover plate 112 harder and not easily deformed.

[0024] like Figure 5 and Figure 6 As shown, the housing 120 is mainly composed of a positioning platform 121, a buckle seat 122, a glue dispensing cavity 123, a glue guide platform 124, a guide block 125, a glue outlet 126, a glue outlet tube 127, a limit block 128 and a housing body 129. The positioning platform 121 is buckled in the positioning groove 114, and the buckle plate 113 is buckled in the four sets of buckle seats 122. There are positioning plates on both sides of the tray of the transmission line B, and the distributor grabbing mechanism 3 grabs the distributor 1, and the distributor 1 moves up and down along the positioning plate of the tray through the guide block 125. In the centrifugal sealing process, the glue injection nozzle of the glue injection machine injects glue near the inclined surface of the hemispherical glue guide platform 124, and the motor drives the turntable to rotate centrifugally at high speed. The polyurethane glue passes through the four glue distribution chambers 123 and the glue outlet 126 and evenly reaches the inner wall of the dialyzer sealing cap; because the two dialyzers are placed crosswise up and down, the glue outlet pipes 127 are two groups of different heights; and the end of the glue outlet pipe 127 is conical, so that the distributor 1 and the dialyzer 2 are installed in a tight fit, and the distributor 1 will be tightly inserted into the dialysate inlet and outlet interface 210 of the dialyzer 2. The limit block 128 can realize the insertion of the distributor 1 into the appropriate position of the dialyzer 2 to prevent the glue outlet pipe 127 from being inserted too long or too short.

[0025] In summary, if Figures 1 to 6 As shown, the positioning groove 114 and the snap plate 113 on the upper cover 110 of the dispenser 1 match the positioning platform 121 and the snap seat 122 of the shell 120 respectively. The upper cover 110 will be tightly fastened to the shell 120. When the dispenser 1 is grabbed and moved, the upper cover 110 of the dispenser 1 will not fall off the shell 120.

[0026] Two dialyzers are loaded in the tray of transmission line B, and the dialyzers are placed crosswise at 70 degrees. The distributor grabbing mechanism 3 clamps the inner diameter of the injection port 111 of the distributor 1 at the transmission line A, and the guide block 125 accurately inserts the distributor 1 into the dialysate inlet and outlet interface 210 of the dialyzer 2 along the positioning plate of the tray; the outlet hose 127 is conical, and the distributor 1 will be inserted tighter and tighter during the insertion process to prevent the distributor 1 from being separated from the dialyzer 2 during the centrifugal sealing process; the limit block 128 enables the outlet hose 127 of the distributor 1 to be inserted into the appropriate position in the interface 210 of the dialyzer 2 to prevent the outlet hose 127 from being inserted too long or too short.

[0027] The dialyzer 2 with the dispenser 1 installed is transferred to the centrifugal sealing process. The glue injection nozzle of the glue injection machine injects glue through the glue injection port 111 close to the inclined surface of the hemispherical glue guide platform 124. The motor drives the turntable to rotate centrifugally at high speed. The polyurethane glue passes through the four glue distribution chambers 123 and the glue outlet 126 and is evenly "thrown" to the inner walls of the sealing caps at both ends of the dialyzer. During the glue injection process, the extended glue baffle plate 115 is extended into the glue distribution chamber 123 to seal the polyurethane glue with the shell 120 to prevent leakage. The reinforcing ribs 116 can make the upper cover plate 112 harder and not easily deformed during the process of grabbing the dispenser 1 and removing the upper cover 110.

[0028] The dispenser 1 adopts a split type of upper cover 110 and shell 120. After completing the sealing and pouring glue process for multiple times, the upper cover 110 is disassembled to facilitate cleaning of residual glue in the shell 120.

[0029] Therefore, the utility model has a reasonable structure, meets the use requirements in the production line, and improves the automation degree of the production line.
