The partition cover 212 is provided with a plurality of workpiece grooves 213. The workpiece clamping mechanism 22 is arranged in the workpiece groove 213.

[0037] It is worth noting that in the embodiment of the present application, the partition cover 212 divides the fixing frame 21 into a plurality of workstations, can accommodate a plurality of workpieces in the workpiece groove 213 at the same time, and realizes batch rubber tape pasting.

[0038] Referring to Figures 2 to 9The workpiece clamping mechanism 22 comprises a workpiece placing plate 221, a placing plate position adjusting mechanism 222 and a workpiece clamping assembly 223. The workpiece placing plate 221 is arranged in the work station groove 213 in a lifting manner. The workpiece placing plate 221 is used for placing a workpiece. The placing plate position adjusting mechanism 222 is arranged on the fixed base 211 and connected with the workpiece placing plate 221. The placing plate position adjusting mechanism 222 can adjust the height of the workpiece placing plate 221. The workpiece clamping assembly 223 is arranged on the fixed base 211 and connected with the placing plate position adjusting mechanism 222, and is used for fixing the workpiece.

[0039] With reference to Figures 2 to 8 The placing plate position adjusting mechanism 222 comprises a sleeve 222a, a rotating sleeve 222c, a fixed sleeve 222e, a rotating ring 222h and an elastic member 222i.

One end of the elastic member 222i abuts against the lower end of the rotating ring 222h, and the other end abuts against the fixed base 211.

[0040] It is worth noting that, in the embodiment of the present application, the workpiece is placed on the workpiece placing plate 221. When the adhesive tape automatic sticking mechanism 30 sticks the adhesive tape on the workpiece, the workpiece is pressed downward, thereby pressing the workpiece placing plate 221 downward, and driving the rotating sleeve 222c to move downward. At this time, the second clamping teeth 222d move along the first clamping grooves 222f. When the second clamping teeth 222d completely leave the first clamping grooves 222f, the rotating sleeve 222c is rotated under the cooperation of the first clamping teeth 222b and the second clamping teeth 222d, so that the second clamping teeth 222d are clamped into the second clamping grooves 222g. Since the second clamping grooves 222g are half grooves, the height of the sleeve 222a is reduced.
