[0028] The limiting assembly 6 includes: a rotating shaft 61, an insertion rod 62, and a pressing rod 63. The middle part of the limiting assembly 6 is fixedly connected to one end of the rotating shaft 61. The axis of the rotating shaft 61 passes through and is rotatably connected to the middle part of the fixing frame 3. The other end of the rotating shaft 61 is fixedly connected to the middle part of the double-headed rod 7. The groove opened at the end of the limiting assembly 6 is slidably connected to the rod body of the insertion rod 62. The groove opened on the side wall in the middle part of the limiting assembly 6 is slidably connected to the rod body of the pressing rod 63.

[0029] The insertion rod 62 also includes: a connecting rod 621 and a spring 622. The end of the insertion rod 62 is fixedly connected to the end of the connecting rod 621. The end face of the connecting rod 621 is fixedly connected to one end of the spring 622. The other end of the spring 622 is fixedly connected to the inner wall of the limiting assembly 6.

[0030] The pressing rod 63 also includes: a spring 631 and a driving block 632. The end of the pressing rod 63 is fixedly connected to the middle of the driving block 632. The rod body of the pressing rod 63 is sleeved with a spring 631. One end of the spring 631 is fixedly connected to the end of the driving block 632.

The other end of the fixed block 72 is fixedly connected to the side of the clamp 4.

[0032] The working principle of the SMT patch dispensing equipment of the utility model is as follows: when fixing the liquid outlet bottle on the fixing frame 3, it is necessary to align the bottom of the liquid outlet bottle with the middle of the predetermined ring 5, and then press the liquid outlet bottle into the predetermined ring 5. At this time, the bottom of the predetermined ring 5 will be clamped by the predetermined ring 5 of the central control cone, and the liquid outlet bottle is pre-fixed, which is convenient for the chuck 4 to clamp the bottle body of the liquid outlet bottle. At this time, the outer wall of the limit component 6 is pinched by hand. In the process of pinching the outer wall of the limit component 6, the hand naturally presses the pressing rod 63. At this time, the pressing rod 63 will drive the driving block 632 to move. At this time, the driving block 632 moves toward the middle of the connecting rod 621, and the driving block 632 is in the shape of a trapezoid. At this time, the connecting rod 621 will be The driving block 632 is pressed against, so that the connecting rod 621 rises, and the insertion rod 62 engaged in the limiting tooth groove 32 is lifted. At this time, the limiting component 6 can be rotated, and the end of the limiting component 6 is fixedly connected to the middle part of the double-headed rod 7. At this time, the rotation of the double-headed rod 7 will cause the connection end of the double-headed rod 7 at the hinged rod 71 to rotate, so that the connection end of the hinged rod 71 at the fixed block 72 moves toward the middle of the double-headed rod 7. At this time, the chuck 4 will clamp the placed liquid outlet bottle tightly. At this time, the limiting component 6 is released, so that the spring 1 631 drives the driving block 632 to reset, and the spring 1 631 drives the insertion rod 62 to reset. At this time, the insertion rod 62 is inserted into the limiting tooth groove 32 again, thereby fixing the double-headed rod 7.

[0033] By rotating the limit assembly 6 to drive the double-headed rod 7 to clamp the liquid outlet bottle, more liquid outlet bottles of different specifications can be fixed by the double-headed rod 7, and this fixing method is more convenient and quicker than the bolt fixing method. The pre-fixation of the liquid outlet bottle by the predetermined ring 5 can keep the liquid outlet bottle in the middle part of the double-headed rod 7 for better positioning. In addition, the setting of the limit assembly 6 can enable the operator to trigger the pressing rod 63 when the watch naturally holds the limit assembly 6 during the process of driving the limit assembly 6 to move. This setting avoids the problem that the operator has difficulty in observing the rear part of the fixing frame 3 and avoids the situation that the operator has difficulty in triggering the pressing rod 63 to drive the limit assembly 6 to rotate.
