[0024] The clamping assembly 6 includes a fixing seat 601, a clamping unit 602, a rotating shaft 603, a mounting cavity 604 and a torsion spring 605;

[0025] The fixing seat 601 is fixed to one end of the outer wall of the mounting plate 102, and two clamping units 602 are provided. The two clamping units 602 are symmetrically distributed on the top of the fixing seat 601, and the clamping units 602 are rotatably connected to the fixing seat 601 through the rotating shaft 603. The two clamping units 602 are wrapped around the outer side of the glue tube 7 to achieve the limited fixation of the glue tube 7;

[0026] The installation cavity 604 is provided at the bottom of the fixing seat 601, the rotating shaft 603 is fixedly connected to the clamping unit 602 and extends through the inside of the installation cavity 604, the torsion spring 605 is sleeved on the outside of the installation cavity 604, and the two ends of the torsion spring 605 are respectively clamped on the inner wall of the installation cavity 604 and the outside of the rotating shaft 603;

[0027] The clamping unit 602 includes an arc-shaped clamping plate 6021, an outward-turned arc piece 6022 and an arc-shaped abutment piece 6023;

[0028] One end of the arc-shaped clamping plate 6021 is fixed to the top of the rotating shaft 603, the outward-turned arc piece 6022 is integrally formed at the other end of the arc-shaped clamping plate 6021, and the arc-shaped abutting piece 6023 is integrally formed at the end of the outward-turned arc piece 6022 away from the arc-shaped clamping plate 6021, and the end of the arc-shaped abutting piece 6023 away from the outward-turned arc piece 6022 extends to the gap between the two arc-shaped clamping plates 6021, and the two arc-shaped abutting pieces 6023 are fitted together, and the ends of the two arc-shaped abutting pieces 6023 are vertically fitted with the outer side of the glue cylinder 7 to limit the outward movement of the glue cylinder 7;

[0029] A glue injection seat 104 is fixedly connected to one end of the bottom of the mounting plate 102, a movable groove 105 is formed on one side of the glue injection seat 104, a glue injection head 2 is installed at the bottom of the glue injection seat 104, a rotating tube 3 penetrating into the glue injection seat 104 is arranged on the inner side of the movable groove 105, the rotating tube 3 is rotatably connected to the glue injection seat 104, and a channel communicating with the glue injection head 2 and the rotating tube 3 is opened inside the glue injection seat 104, a docking joint 4 is fixedly connected to one side of the rotating tube 3, and the docking joint 4 is used to support the bottom end of the glue cylinder 7;

[0030] The distribution center line of the two arc-shaped clamping plates 6021 coincides with the center line of the docking joint 4 . A sealing rubber ring 5 is bonded and fixed inside the docking joint 4 , and the inner cavity of the docking joint 4 is in conduction with the inner cavity of the rotating tube 3 .

[0031] In this embodiment: it should be supplemented that: the two-axis slide 101 can realize the horizontal and vertical movement of the glue injection head 2, and the middle part of the two-axis slide 101 is equipped with a conveying component that drives the diode to be conveyed horizontally and longitudinally. The glue cylinder 7 is usually stuck between the two arc-shaped clamping plates 6021, and the end of the glue cylinder 7 is inserted into the inside of the docking head 4, and the sealing rubber ring 5 is sleeved on the outside of the end of the glue cylinder 7 to achieve sealing. The high-pressure gas can be conveyed into the glue cylinder 7 through an external air pump, and the glue inside the glue cylinder 7 can be squeezed and conveyed to the glue injection head 2, so as to realize the packaging operation of the diode;

[0032] When the glue inside the glue tube 7 is used up and needs to be replaced, the top plug cover 103 and the air supply channel of the external air pump can be closed first, and the high pressure inside the glue tube 7 can be relieved. Then, manually press between the two arc-shaped retaining pieces 6023 to deform the arc-shaped retaining pieces 6023 under force, and the end of the arc-shaped retaining piece 6023 deviates from the outer wall of the glue tube 7, so that the end of the arc-shaped retaining piece 6023 and the outer wall of the glue tube 7 are released from the vertical state. At this time, the glue tube 7 is pulled outward, and the glue tube 7 will rotate outward with the rotating tube 3 as the center. , the outer wall of the glue cylinder 7 further squeezes the arc-shaped abutment piece 6023, and this squeezing force causes the clamping unit 602 to rotate as a whole around the rotating shaft 603, and the rotating shaft 603 causes the torsion spring 605 to twist and deform. By moving the two clamping units 602 away from each other, the glue cylinder 7 can be moved to the outside of the two clamping units 602. At this time, the glue cylinder 7 can be pulled upward to separate it from the docking head 4, and finally the top plug cover 103 can be separated from the glue cylinder 7, and the disassembly of the glue cylinder 7 is completed;

[0033] When installing a new glue cylinder 7, first install the top plug cover 103 and the glue cylinder 7, then slightly tilt the glue cylinder 7 so that its end is aligned with the inclined docking head 4 and inserted, and then rotate the glue cylinder 7 to make it close to the clamping unit 602. At this time, the outer wall of the glue cylinder 7 will contact the two arc-shaped abutment pieces 6023 so that the two clamping units 602 are separated from each other, so that the glue cylinder 7 can be smoothly inserted into the middle of the two clamping units 602. Finally, the two clamping units 602 are 02 will be reset under the action of the torsion spring 605, and the arc-shaped clamping plate 6021 is attached to the outer wall of the glue tube 7 to limit the position of the glue tube 7. At the same time, the arc-shaped abutment 6023 is also reset under the action of its own elastic force. At this time, the end of the arc-shaped abutment 6023 is in a vertical state with the outer wall of the glue tube 7, so that when the glue tube 7 rotates outward, the force on the arc-shaped abutment 6023 is in a vertical state. This vertical force will not cause the clamping unit 602 to rotate, thus ensuring the stability of the limit of the glue tube 7;

[0034] The glue tube 7 can be conveniently replaced by cooperating with the above-mentioned multiple parts. Compared with the traditional bolt fixing method, the operation steps are fewer and the operation is simpler, which can further improve the replacement efficiency of the glue tube 7.

[0035] Please refer to Figures 1 to 3 The outer wall of the lower half of the butt joint 4 is in a conical structure, the outer wall of the upper half of the butt joint 4 is in a cylindrical shape, and one end of the inner wall of the movable groove 105 is formed with an arc groove matching the outer wall of the upper half of the butt joint 4.

[0036] In this embodiment: the outer wall of the upper half of the docking joint 4 fits into the arc groove, so that the docking joint 4 can only be rotated to a state where the port is vertically facing upward. At the same time, since the lower half of the docking joint 4 is a conical structure, there is a certain space between the lower half of the docking joint 4 and the arc groove, which provides space for the downward rotation of the docking joint 4 and also limits the downward rotation angle of the docking joint 4 to avoid excessive deflection of the docking joint 4.

[0037] Please refer to Figures 1 to 4 The arc-shaped splint 6021, the outward-turned arc piece 6022, the arc-shaped abutment piece 6023 and the rotating shaft 603 can be integrally formed by an injection molding process, and the arc-shaped abutment piece 6023 has a certain elasticity.

[0038] In this embodiment: the one-piece molding is performed by injection molding process, so that it is easy to produce and promote. The arc-shaped abutment piece 6023 can realize automatic reset through its own elasticity, thereby realizing automatic limit operation of the glue tube 7.
