[0002] In the assembly process of the compressor cylinder, the water pipe needs to be bonded at the corresponding position, and the bonding angle and bonding strength of the water pipe also need to be ensured.

[0003] The current processing method requires an operator to use a brush or a dispensing pen to uniformly apply the adhesive to the outer circle of the water pipe, and then place it in the fixed position of the press-fitting machine for press-fitting and bonding. This processing method is not efficient, and it is difficult to accurately control the application range and application amount of the adhesive, which may result in insufficient adhesive application, weak bonding, or excessive adhesive application, causing the adhesive to overflow and drip on other parts of the part, affecting product quality. Therefore, there is an urgent need for an efficient gluing device that can accurately control the amount of glue. SUMMARY

[0017] like Figures 1-3 As shown, a rotary adhesive applicator includes a worktable 1, on which a water pipe rotary clamping assembly is mounted. The assembly includes a stepper motor 2 mounted via a first mounting plate 12, and a pneumatic slip ring 5 connected to the output shaft of the stepper motor 2 via a coupling 3. The pneumatic slip ring 5 is connected to the worktable 1 via a second mounting plate 14.

[0018] A transition plate 6 is connected to one end of the pneumatic slip ring 5. A gripper cylinder 7 is mounted on the transition plate 6, and three grippers 11 are mounted on the gripper cylinder 7. The grippers 11 are L-shaped, with one end of each gripper 11 converging towards the center so that one end of the water pipe 13 can be inserted into one end of each gripper. A water pipe insertion section 11b with a reduced diameter is provided at one end of each gripper 11, and a groove 11a corresponding to the inner wall of the water pipe is provided between the water pipe insertion section 11b and the main body of the gripper 11. When the gripper cylinder is activated, it drives the grippers 11 to move outward, causing one end of each gripper to tighten inside the water pipe.

[0019] A movable glue applicator fixing assembly 8 is also provided on the workbench 1 on one side of the water pipe rotating clamping assembly. The glue applicator fixing assembly 8 includes a slide rail 8a, the axis of which is perpendicular to the axis of the stepper motor 2. A corresponding slider 8b is provided on the slide rail 8a, and a power output device 8c, which is a cylinder, is provided at one end of the slide rail 8a to form a power transmission connection with the slider 8b. The power output device 8c drives the slider 8b to move on the slide rail 8a, and a glue applicator fixing bracket 8d is provided on the slider 8b.

[0020] The glue head fixing frame 8d includes vertical poles a fixed on the upper surface of the sliding block 8b, a first locking assembly b provided on the vertical poles a, a rotatable first suspension rod c provided on the first locking assembly b, a rotatable clamping ring d connected to one end of the first suspension rod c and forming a clamping cooperation with the glue head 9, and a locking pin (not shown in the figure) provided on the clamping ring d and forming a locking cooperation with the glue head 9.

[0021] The first locking assembly b includes a clamping groove b1 and a locking sleeve b2 of an integral structure, a locking bolt b3 provided through the clamping groove b1 and the locking sleeve b2, a pressing piece b4 provided on the locking bolt b3 and corresponding to the clamping groove b1, and a hand wheel b5 provided on the locking bolt b3.

[0022] The clamping groove b1 is clamped on the vertical pole a, and the other end of the first suspension rod c is inserted into the locking sleeve b2. By rotating the hand wheel b5, the pressing piece b4 on the locking bolt b3 progressively extrudes the groove wall of the clamping groove b1 to lock the clamping groove b1 on the vertical pole a, and at the same time, the end of the locking bolt b3 is screwed into the locking sleeve b2 to lock the first suspension rod c.

[0023] An injection machine 10 is provided on the workbench 1, and the glue outlet of the injection machine 10 is communicated with the glue head 9 through a telescopic hose (not shown in the figure). An operation table 4 is provided on the workbench 1 and forms a control cooperation with the stepping motor 2, the clamping jaw air cylinder 7, the glue head fixing assembly 8, and the injection machine 10. A control module is provided on the operation table 4 and forms a corresponding cooperation with the stepping motor 2, the clamping jaw air cylinder 7, the glue head fixing assembly 8, and the injection machine 10.

[0024] Working process:

[0025] Firstly, the staff inserts the tubular part (i.e. the water pipe 13) to be glued into the three clamping jaws, and then expands the clamping jaws in the water pipe by starting the corresponding clamping jaw air cylinder on the operation table 11. Then, the power output device is extended by starting the lower air cylinder, the glue head fixing assembly is adjusted according to the size of the tubular part to adjust the glue head to a suitable height and angle, so that the glue outlet is aligned with the area of the part to be glued, and then the first locking assembly and the clamping ring are locked. Finally, the control cylinder is reset, and the injection machine is started to inject a certain amount of adhesive (glue) into the glue head.

[0026] Finally, the stepping motor is started by the control module to drive the tubular part to rotate, and the glue head automatically glues. When the set gluing time is reached, the glue head stops gluing, and then the stepping motor stops rotating. Then, the clamping jaws are retracted by the control module, and the part is taken off, i.e. one automatic gluing operation is completed. The above-mentioned expansion of the part and the starting of the stepping motor are repeated to complete the gluing operation.
