A positioning slot 734 is formed inside the baffle plate 72 at a position corresponding to the positioning block 733. The magnetic plate 732 is installed inside both the positioning slot 734 and the positioning block 733.

[0027] By adopting the above technical solution, the positioning card block 733 engages with the positioning card slot 734, and then is magnetically fixed by the magnetic plate 732, so that the collection box 731 can be stably installed and can achieve the collection effect.

[0028] Specifically, the shielding assembly 7 also includes a triangular plate 75 and a horizontal plate 76. The horizontal plate 76 is fixed to the surface of the mounting plate 71 and located at the lower end of the shielding plate 72, and the triangular plate 75 is installed between the mounting plate 71 and the horizontal plate 76.

[0029] By adopting the above technical solution, the horizontal plate 76 can support the shielding plate 72, making its structure more stable, and the triangular plate 75 can provide auxiliary reinforcement.

[0030] In this embodiment, the workbench 5 is moved and fixed in a suitable position. The adjustment component 6 is activated, and the lifting platform 4 is moved to a suitable height. The patch is placed on the upper end of the feeding component 2. The first electric push rod 1 at the upper end of the support column 3 is activated, which drives the dispensing structure 8 at the upper end of the crossbeam 9 to rise and fall. The dispensing structure 8 is activated to automatically dispense glue to the patch, which can easily complete the dispensing and patching operation. The drive motor drives the rotating shaft 74 to rotate, which can drive the shielding plate 72 to rotate within the mounting plate 71, so that it can shield the lower end of the dispensing structure 8 and prevent residual glue from dripping onto the lifting platform 4.

[0036] In this embodiment, the patch is placed inside the positioning cylinder 22. The connecting spring 25 presses the arc-shaped clamp 26 to fix the patch. The rotating motor 23 drives the rotating table 21 to rotate, which can rotate the positioning cylinder 22. This allows another set of patches to be placed while dispensing glue, resulting in high work efficiency. After the patch is dispensed, the round rod 24 is pushed to move the push plate 27 upward, so that the patch can be easily removed.

[0037] The structure and working principle of the first electric push rod 1, the adjusting component 6, and the dispensing structure 8 consisting of a cylinder, a piston rod, and a dispensing cylinder in this utility model have been disclosed in an SMT automatic dispensing device disclosed in Chinese patent application number 202220138091.5. The working principle of the first electric push rod 1 is to convert the rotational motion of the motor into the linear reciprocating motion of the push rod. The working principle of the adjusting component 6 is that the output end of the motor drives the screw to rotate. The screw is threadedly connected to the threaded cylinder, and the threaded cylinder is slidably connected to the worktable 5 through a slider and a groove, so that the threaded cylinder can drive the lifting platform 4 to move vertically. The working principle of the dispensing structure 8 is that the cylinder drives the piston rod to press down and squeeze the glue in the dispensing cylinder, thereby realizing the dispensing operation.

[0038] The working principle and usage process of this utility model are as follows: When using this utility model, the workbench 5 is moved and fixed in a suitable position. The adjustment component 6 is activated to move the lifting platform 4 to a suitable height. The patch is placed on the upper end of the feeding component 2. The first electric push rod 1 at the upper end of the support column 3 is activated, which drives the dispensing structure 8 at the upper end of the crossbeam 9 to rise and fall. The dispensing structure 8 is activated to automatically dispense glue to the patch, which can easily complete the dispensing and patching operation. The drive motor drives the rotating shaft 74 to rotate, which can drive the shielding plate 72 to rotate within the mounting plate 71, thereby shielding the lower end of the dispensing structure 8 to prevent residual glue from dripping onto the lifting platform 4. The collection structure 73 can collect and recycle the dripped glue, making the positioning... The card block 733 engages with the positioning slot 734 and is then magnetically fixed by the magnetic plate 732, which can stably install the collection box 731 so that it can play a collecting role. The horizontal plate 76 can support the shielding plate 72, making its structure more stable, and the triangular plate 75 can provide auxiliary reinforcement. The patch is placed inside the positioning cylinder 22, and the connecting spring 25 can press the arc-shaped clamping plate 26 to fix the patch. The rotating motor 23 drives the rotating table 21 to rotate, which can make the positioning cylinder 22 rotate, so that another set of patches can be placed at the same time as dispensing glue, which has high work efficiency. After the patch is dispensed, the round rod 24 is pushed to move the push plate 27 upward, so that the patch can be easily removed.
