[0040] The clamping fixture includes, from left to right, a first gasket 19, a spring 20, a second gasket 21 and a nut 22, which are sleeved on the driving sleeve 18. The spring 20 is in a compressed state, and the first gasket 19 and the second gasket 21 are fixedly connected to the two ends of the spring 20, respectively. The first gasket 19 contacts the driving rim 24 under the pressure of the spring 20, and the nut 22 is threadedly connected to the right end of the driving sleeve 18. By controlling the axial position of the nut 22 in the driving sleeve 18, the spring 20 in a compressed state drives the first gasket 19 to limit the driving rim 24 between the first gasket 19 and the shoulder of the driving sleeve 18, that is, the driving rim 24 is pressed against the driving sleeve 18.

[0041] 2. Driven wheel assembly 4

[0042] The driven wheel assembly 4 is used to realize the unwinding function of the double-sided adhesive tape 3.

The first gasket 19 contacts the driven wheel rim 25 under the pressure of the spring 20, and the nut 22 is threadedly connected to the right end of the driven shaft sleeve 26. By controlling the axial position of the nut 22 on the driven shaft sleeve 26, the spring 20 in a compressed state drives the first gasket 19 to limit the driven wheel rim 25 between the first gasket 19 and the shaft shoulder of the driven shaft sleeve 26, that is, the driven wheel rim 25 is pressed against the driven shaft sleeve 26.

[0044] 3. Press wheel assembly

[0045] The pressing wheel assembly is used to press the sticky double-sided adhesive 7 separated from the double-sided adhesive tape 3 onto the material. Figure 1 As shown, the pressure wheel assembly is placed below the driving wheel assembly 1 and the driven wheel assembly 4, and placed between the two. The pressure wheel assembly includes a pressure wheel 9 and a pressure wheel driving member.

[0046] The pressing wheel 9 is fixedly connected to the pressing wheel mounting bracket 10, and the pressing wheel mounting bracket 10 is fixed to the pressing wheel driving member. The pressing wheel driving member is a mechanism that can drive the pressing wheel 9 to press or leave the adhesive position, that is, a mechanism that can drive the pressing wheel 9 to move up and down linearly. The pressing wheel driving member can be a cylinder structure, a hydraulic cylinder structure, or an electric cylinder structure in the prior art. In this embodiment, the pressing wheel driving member is a cylinder mechanism, that is, a pressing wheel cylinder, and the pressing wheel cylinder adopts a slide cylinder in the prior art.

[0047] 4. Guide wheel assembly

The guide wheel assembly includes a first guide wheel 6 disposed between the driven wheel assembly 4 and the pressure wheel assembly, and a second guide wheel 27 disposed between the driving wheel assembly 1 and the pressure wheel assembly. The first guide wheel 6 and the second guide wheel 27 can be fixedly connected to the mounting base plate 2 through a shaft sleeve.

[0049] 5. Cut off components

[0050] The cutting component is used to cut off the sticky double-sided adhesive 8 after the gluing work is completed. The cutting component is placed between the highest point and the lowest point of the pressing wheel 9 when it moves up and down in a straight line. Figure 2 As shown, the cutting assembly includes a blade 7 and a blade driving member.

[0051] The blade 7 is fixedly connected to the blade mounting frame 13, and the blade mounting frame 13 is fixedly connected to the blade driving member. The blade driving member is a mechanism that can drive the blade 7 to rotate and cut the sticky double-sided colloid 8. In this embodiment, the blade driving member is a swing cylinder 14 that can horizontally rotate the blade 90 degrees. The swing cylinder 14 adopts a rotary cylinder in the prior art. The swing cylinder 14 is fixed to a swing cylinder bracket 15, and the swing cylinder bracket 15 is fixedly connected to the mounting base plate 2.

[0052] When gluing, the extending direction of the blade 7 is aligned with the material running direction. In other words, the extending direction of the blade 7 is aligned with the extending direction of the adhesive double-sided glue 13. Figure 1 The right side of the pressing wheel 9 is to prevent the blade 7 from cutting the sticky double-sided adhesive 13 when gluing the material. When the gluing work is completed, refer to Figure 5 and Figure 6 As shown, the pressing wheel 9 is moved upward, and the pressing wheel 9 no longer presses the viscous double-sided adhesive 13 on the material. At this time, the blade 7 is placed under the pressing wheel 9, so that the blade 7 is horizontally rotated 90° to contact the viscous double-sided adhesive 13 to cut the viscous double-sided adhesive 13.

[0053] 6. Detection components

[0054] The detection assembly includes a first sensor 5 and a second sensor 16 both fixedly connected to the mounting substrate 2. Figure 1 As shown, the first sensor 5 is placed above the viscous double-sided glue 8 to detect whether the viscous double-sided glue 8 is pressed on the material to prevent the viscous double-sided glue 8 from leaking on the material. In this embodiment, the first sensor 5 is a laser sensor in the prior art.

[0055] refer to Figure 2 As shown, the second sensor 16 is fixed on the swing cylinder bracket 15, and the second sensor 16 is used to detect the position to be glued, so that the viscous double-sided glue 81 is glued to the position of the material to be glued. The second sensor 16 adopts a laser sensor in the prior art. The material to be glued has a joint, and the second sensor 16 detects that the joint on the material is the position to be glued. The control signal output end of the second sensor 16 is connected to the control signal input end of the walking mechanism. The walking mechanism is a structure that can drive the driven wheel assembly 4, the driving wheel assembly 1, the cutting assembly, the guide wheel assembly and the detection assembly on the mounting substrate 2 to move as a whole to the position to be glued, that is, the walking mechanism is fixedly connected to the mounting substrate 2. The walking mechanism can use the cylinder structure commonly used in the prior art. In this embodiment, the walking mechanism adopts the rodless cylinder in the prior art, and the control signal input end of the walking cylinder is connected to the signal output end of the second sensor 16. The walking mechanism can also use the electric cylinder mechanism in the prior art, and can use the sealing belt type thin electric actuator in the prior art, and the control signal input end of the electric cylinder is connected to the signal output end of the second sensor 16.

[0056] When gluing the material using this embodiment, the pressing wheel 9 is first moved to the top of the material to be glued by the walking mechanism, and then the reduction motor 17 drives the driving rim 24 to drive the double-sided adhesive waste 12 fixed on the driving rim 24 to rotate clockwise (refer to Figure 1 The double-sided adhesive tape 3 is driven by the double-sided adhesive waste 12 to rotate, so that the double-sided adhesive tape 3 is unwound by the driven shaft sleeve 26 in a counterclockwise rotation; then, the pressing wheel 9 moves downward under the action of the pressing wheel cylinder to press the sticky double-sided adhesive 8 on the material; at the same time, the extension direction of the blade 7 is consistent with the material running direction, that is, Figure 1 The middle blade 7 and the sticky double-sided colloid 8 are all placed on the right side of the pressing wheel 9, and the material is transported to the right. Like this, in the process of material transporting to the right, the pressing wheel 9 presses down the sticky double-sided colloid 8 to stick on the material.

[0057] When the present embodiment is used to finish gluing the material, first, the pressing wheel cylinder moves the pressing wheel 9 upward so that the pressing wheel 9 is placed above the blade 7; then, the swing cylinder 14 drives the blade 7 to rotate horizontally by 90° so that the blade 7 contacts the viscous double-sided glue 8, thereby cutting the viscous double-sided glue 8.
