[0050] Example 2

[0051] like Figure 1 The workbench 6 shown divides the equipment into two functional areas: the upper part of the workbench 6 is the area for loading and coating drug cartridges, and the lower part is the area for mixing and recycling colloids. The drug cartridge conveying device 2, drug cartridge positioning device 3, colloid mixing assembly 4, and drug cartridge rotating device 5 are bolted to the upper surface of the workbench 6. The track of the drug cartridge loading device 1 is bolted to the inner side of the top of the workbench 6. The control box 7 is screwed to the outer right side of the workbench cover. The polyamide storage device 8 and epoxy resin storage device 9 are fixed to the lower left side of the workbench, and their feed ports pass through the upper part of the workbench 6. The precision gear pump 10 and cleaning device 11 are bolted to the bottom of the workbench. The precision gear pump 10 is connected to the polyamide storage device 8, epoxy resin storage device 9, and colloid mixing assembly 4 via hoses. The cleaning device 11 is connected to the colloid mixing assembly 4 via hoses.

[0052] The cartridge taking and placing device 1 is composed of a track, a connecting rod and a suction cup to realize the cartridge grabbing, moving and placing. The cartridge conveying device 2 is composed of a tray, a rotating shaft and a cylinder to realize the conveying of the uncoated cartridge and the finished cartridge. The cartridge positioning device 3 is composed of a positioning column and a tray to assist the cartridge taking and placing device 1 to fix one side end face of the cartridge. The glue mixing assembly 4 is mainly composed of a glue mixing valve, a pneumatic motor and a glue coating plate to coat the surface of the cartridge. The cartridge rotating device 5 is composed of a fixed disc, a rotating shaft and a pneumatic motor to realize the fixing of the other side end face of the cartridge and the rotation of the cartridge, and to cooperate with the glue mixing assembly to coat the cartridge. The control box 7 is composed of a control panel, a PLC and control elements such as air valves to control the operation of the equipment. The polyamide storage device 8 and the epoxy resin storage device 9 are composed of a storage tank and a stirrer to mix and store the glue. The cleaning device 11 is composed of a cleaning liquid storage tank and a pneumatic diaphragm pump to clean the glue coating port.

[0053] First, the glue preparation work is carried out. The polyamide and epoxy resin are mixed with various dry powders according to the proportion by manual and then put into the polyamide storage device 8 and the epoxy resin storage device 9. The stirring cylinder in the two storage devices starts continuous stirring to maintain the uniform mixing degree of the two glues and dry powders. The two mixed glues in the storage devices are transported to the precision gear pump 10 by the glue pump through the glue pipe, and then the two different glues are simultaneously transported to the glue mixing valve through the precision gear pump 10. The two glues are uniformly mixed together through the glue mixing valve and then enter the glue mixing assembly 4, so the glue preparation work is completed and the conditions for coating the surface of the cartridge are met. The cartridge loading work is carried out by placing the cartridge on the cartridge conveying device 2 through the external grabbing device. After the cartridge conveying device 2 detects the cartridge, the cartridge is conveyed to the fixed position below the cartridge taking and placing device 1 through the rotating action. The suction cup on the cartridge taking and placing device 1 sucks the cartridge and turns it over by 90° to place the cartridge horizontally on the cartridge positioning device 3. After the cartridge is placed stably, the cartridge taking and placing device 1 is separated. The cartridge rotating device 5 feeds and clamps the two ends of the cartridge together with the cartridge positioning device 3 to fix the cartridge horizontally in the air. After the cartridge is fixed, the cartridge rotating device 5 rotates, and at the same time, the glue mixing assembly 4 moves to the vicinity of the cartridge to start coating the surface of the cartridge. After the coating is completed, the cartridge is taken back by the cartridge taking and placing device 1 and placed on the cartridge conveying device 2, and the whole automatic coating process is completed. The cartridge rotating speed and the glue flow can be adjusted through the control box 7. In order to protect the glue mixing assembly 4 and prevent the glue from solidifying in the glue mixing assembly 4 to block the glue injection port, the equipment has an automatic cleaning function. After the coating work is completed, the cleaning liquid in the cleaning device 11 is injected into the glue mixing assembly 4 through the cleaning pump to clean the glue mixing assembly 4. The waste liquid after cleaning is recycled back to the cleaning device 11 for filtration, sedimentation and other recovery treatments.

[0054] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and deformations can be made, and these improvements and deformations should also be considered as the protection scope of the present application.
