[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] Embodiment 1: The utility model provides a red glue dispensing device, including a main body 1, including a fixed plate 101, a glue cartridge 108 arranged on the fixed plate 101, a glue dispensing valve 105 arranged at the front end of the glue cartridge 108, a connecting plate 104 arranged at the rear end of the glue cartridge 108, a joint 103 arranged on the connecting plate 104, and a movable plate 102 respectively arranged on the glue dispensing valve 105 and the connecting plate 104; a protective mechanism 2, including a protective shell 201 rotatably arranged on the fixed plate 101, and a heating element arranged on the protective shell 201; and an adjusting mechanism 3, arranged between the fixed plate 101 and the movable plate 102.

[0026] Specifically, a fixing block 203 is disposed on the fixing plate 101 at the top of the protective shell 201 , and a limit bolt 202 is threadedly connected to the fixing block 203 . The protective shell 201 is located outside the rubber cylinder 108 .

[0027] Furthermore, the heating element includes a heating plate 204 disposed inside the protective shell 201 , and a heating module 205 disposed on the dispensing valve 105 .

[0028] As can be seen from the above, during operation, the device is installed on the driving structure of the solder paste printer or the glue dispensing machine through the fixing plate 101, and then the connecting plate 104 is connected to the external air pressure delivery mechanism through the joint 103. When it is necessary to dispense red glue, the air pressure is delivered to the glue cylinder 108 through the joint 103, so that the red glue in the glue cylinder 108 is guided out through the glue dispensing valve 105 for glue dispensing. During the glue dispensing process, the heating plate 204 and the heating module 205 can be started, and the heating module 205 will heat the glue at the glue dispensing valve 105, and the heating plate 204 will heat the glue in the glue cylinder 108 to avoid the glue being scalded due to cold weather. In the event that the glue solidifies and affects the glue dispensing work, the protective shell 201 will shield and protect the glue cylinder 108 during operation to prevent the glue cylinder 108 from hitting the external structure and causing damage and leakage during the glue dispensing process. When the glue cylinder 108 needs to be replaced or disassembled for maintenance, it is only necessary to rotate the limit bolt 202, and the limit bolt 202 will move up and down on the fixed block 203 through the threaded connection relationship with the fixed block 203 until the limit bolt 202 is separated from the protective shell 201. At this time, the protective shell 201 can be rotated open to expose the glue cylinder 108, which is convenient for personnel to replace or disassemble the glue cylinder 108 for maintenance.

[0029] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the adjustment mechanism 3 includes a worm gear 301 arranged in the fixed plate 101, a bearing 302 arranged between the worm gear 301 and the fixed plate 101, a threaded rod 304 arranged at both ends of the worm gear 301, a worm 303 is arranged in the fixed plate 101 at the top of the worm gear 301, and limiting rods 305 are arranged in the fixed plate 101 at the top and bottom of the threaded rod 304.

[0030] Specifically, the worm wheel 301 is meshed with the worm 303 , the threaded rod 304 penetrates the fixed plate 101 and is threadedly connected with the movable plate 102 , and two ends of the limiting rod 305 penetrate the two movable plates 102 respectively.

[0031] Furthermore, a holder 106 is disposed on the fixing plate 101 outside the rubber tube 108 , and elastic clips 107 are disposed on the holder 106 at the top and bottom of the rubber tube 108 .

[0032] As can be seen from the above, when it is necessary to disassemble the rubber cartridge 108, it is only necessary to rotate the worm 303. The worm 303 will drive the worm 301 to rotate through the meshing relationship with the worm wheel 301, thereby driving the two threaded rods 304 to rotate. The thread directions of the two threaded rods 304 are opposite. When the threaded rods 304 rotate, the two movable plates 102 will be driven to separate and move synchronously, thereby driving the dispensing valve 105 and the connecting plate 104 to move until the dispensing valve 105 and the connecting plate 104 are separated from the rubber cartridge 108 at the same time. At this time, the rubber cartridge 108 can be pulled to remove it from the fixed plate 101, which is convenient for personnel to disassemble the rubber cartridge 108. When cleaning and maintenance are completed or a new rubber cartridge 108 is replaced, it is only necessary to remove the rubber cartridge 108 from the fixed plate 101. It is pressed into the holder 106, and the rubber cylinder 108 will squeeze it open when it contacts the elastic clip 107. After the rubber cylinder 108 passes the elastic clip 107 and fits with the holder 106, the elastic clip 107 will return to its original position due to its own elasticity, thereby preliminarily limiting the position of the rubber cylinder 108 to prevent it from detaching from the holder 106. Subsequently, the worm 303 is rotated in the opposite direction to drive the two movable plates 102 to move synchronously until the dispensing valve 105 and the connecting plate 104 are in contact with the rubber cylinder 108 at the same time, so as to further limit the position of the rubber cylinder 108, ensure the stability of use, and quickly complete the disassembly, assembly and replacement of the rubber cylinder 108, thereby improving work efficiency and facilitating personnel use.
