The linear guide rails one 811 are two linear guide rails arranged in parallel, and the linear guide rails one 811 are arranged along the moving direction of the telescopic rod of the lifting driving power source 82.

[0028] Referring to Figure 3 , 4 The rotating workbench 1 comprises a rotating driving motor 11, a driving wheel 12, a driven wheel 13, a gear belt 14, a gear box 15, a rotating disc 16 and a fixed support base 17. The rotating driving motor 11 and the gear box 15 are both mounted on the fixed support base 17. The driving wheel 12 is connected with the rotating shaft of the rotating driving motor 11. The gear belt 14 is sleeved on the driving wheel 12 and the driven wheel 13. The driven wheel 13 is connected with the input end of the gear box 15. The rotating disc 16 is connected with the output end of the gear box 15. The plurality of point gluing jigs 2 are arranged on the rotating disc 16. The cross section of the rotating disc 16 is circular. Preferably, the number of the plurality of point gluing jigs 2 is four, and the four point gluing jigs 2 are arranged on the rotating disc 16 in a circular array. During the rotating disc 16 rotates the point gluing jig 2 by 360°, the point gluing jig 2 passes through a feeding position (a feeding position for a point gluing workpiece), a point gluing position, a discharging position and an idle waiting position. After the point gluing jig 2 is fed with a point gluing workpiece, the rotating disc 16 rotates the point gluing jig 2 after feeding to be directly below the screw valve 5. After the point gluing jig 2 is positioned by the centering assembly 7, the lifting driving power source 82 drives the driving friction wheel 85 to contact the point gluing jig 2. The driving motor 84 drives the driving friction wheel 85 to rotate, thereby rotating the point gluing jig 2 to perform point gluing on the circumference of the point gluing workpiece.

[0029] Referring to Figure 5As shown, the dispensing jig 2 comprises a bearing seat 21, a friction rotating wheel 22, a dispensing rotating rod 23, a material returning rod 24, a reset spring 25 and a material returning push ring 26. The bearing seat 21 is fixedly installed on the rotating disc 16. The dispensing rotating rod 23 is arranged on the bearing seat 21 and rotationally connected with the bearing seat 21. The friction rotating wheel 22 and the material returning push ring 26 are respectively sleeved on two ends of the dispensing rotating rod 23. One end of the material returning rod 24 is arranged in the dispensing rotating rod 23, and the other end of the material returning rod 24 arranged in the dispensing rotating rod 23 is connected with the material returning push ring 26. The reset spring 25 is sleeved on the end of the material returning rod 24 extending out of the dispensing rotating rod 23, and is used to provide elastic restoring force of the material returning rod 24. After the lifting driving power source 82 drives the driving friction wheel 85 to contact with the friction rotating wheel 22, the driving motor 84 drives the driving friction wheel 85 to rotate so as to drive the friction rotating wheel 22 to rotate. Since the friction rotating wheel 22 and the dispensing rotating rod 23 are relatively fixed, the dispensing rotating rod 23 rotates. Since one end of the dispensing rotating rod 23 is sleeved with the dispensing workpiece, the dispensing workpiece rotates 360° along with the dispensing rotating rod 23, and the screw valve 5 dispenses one circle on the outer circumference of the annular dispensing workpiece.

[0030] In the above structure, the bearing seat 21 is provided with bearings 211, and the dispensing rotating rod 23 is connected with the inner rings of the bearings 211. The bearings 211 are provided in two, which can ensure that the dispensing rotating rod 23 stably rotates relative to the bearing seat 21. The dispensing rotating rod 23 is a cylindrical rod, and the outer circumference of the end of the dispensing rotating rod 23 sleeved with the dispensing workpiece is provided with an annular groove 232. When the dispensing workpiece is sleeved on the dispensing rotating rod 23, the annular groove 232 is covered. The annular groove 232 can avoid that the friction force or the viscous force between the dispensing workpiece and the dispensing rotating rod 23 is too large, so that the dispensing workpiece is difficult to return. The end of the material returning rod 24 extending out of the dispensing rotating rod 23 is threadedly connected with a screw 231. One end of the reset spring 25 abuts against the end of the dispensing rotating rod 23, and the other end of the reset spring 25 abuts against the head of the screw 231.

[0031] In the structure, one end of the glue dispensing rotating rod 23 is sleeved with the material returning pushing ring 26, the other end of the material returning pushing ring 26 is provided with a waist-shaped hole 233, and the fastener connected between the material returning rod 24 and the material returning pushing ring 26 penetrates through the waist-shaped hole 233. The material returning rod 24 and the material returning pushing ring 26 can be connected together through a screw or a pin. The material returning rod 24 is a cylindrical rod, the axis direction of the glue dispensing rotating rod 23 is provided with a circular through hole 234, the material returning rod 24 is arranged in the circular through hole 234, and the material returning rod 24 can move along the axis direction of the glue dispensing rotating rod 23. Since the material returning rod 24 and the material returning pushing ring 26 are connected together, the material returning rod 24 drives the material returning pushing ring 26 to move when the material returning rod 24 moves. However, the material returning pushing ring 26 is sleeved outside the glue dispensing rotating rod 23, so the material returning pushing ring 26 moves along the outer wall of the glue dispensing rotating rod 23. With the movement of the material returning pushing ring 26, the material returning pushing ring 26 contacts the workpiece on which glue dispensing is completed and is sleeved on the glue dispensing rotating rod 23, so that the material returning pushing ring 26 pushes the workpiece after glue dispensing from the glue dispensing rotating rod 23, thereby completing the discharging of the workpiece.

[0032] Referring to Figure 6 As shown in the figure, the fixed support frame 3 is provided with a material returning assembly 9, and the material returning assembly 9 is used for driving the material returning rod 24 to move linearly. The material returning assembly 9 comprises a material returning driving power source 91, a connecting plate 92 and a pushing rod 93. The material returning driving power source 91 is installed on the fixed support frame 3. One end of the pushing rod 93 is connected to the material returning driving power source 91 through the connecting plate 92. The material returning driving power source 91 drives the pushing rod 93 to push the material returning rod 24. The lifting driving power source 82 and the material returning driving power source 91 are both air cylinders.

[0033] Referring to Figure 3 As shown in the figure, the centering assembly 7 comprises a positioning driving cylinder 71, a positioning bearing seat 72 and a centering pin 73. The positioning driving cylinder 71 is installed on the centering support frame 6. The positioning bearing seat 72 is connected to the output end of the positioning driving cylinder 71. The centering pin 73 is arranged on the positioning bearing seat 72. After the rotating workbench 1 rotates the glue dispensing jig 2 on which the workpiece to be glued is loaded to be opposite to the centering pin 73, the piston rod of the positioning driving cylinder 71 is extended to push the centering pin 73 to abut against one end of the glue dispensing rotating rod 23 on which the workpiece to be glued is arranged. Through the centering pin 73, the workpiece to be glued can be limited on the glue dispensing rotating rod 23, so as to avoid the workpiece to be glued from falling off the glue dispensing rotating rod 23. The positioning support frame 71 is provided with a glue receiving box 74, and the glue receiving box 74 is located directly below the centering pin 73. In this way, when the screw valve 5 dispenses glue on the workpiece, the excess glue can fall into the glue receiving box 74.

[0034] Obviously, the above embodiments are only examples for clearly illustrating the present application and are not intended to limit the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be enumerated, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
