Description

Technical Field

[0001] The present application relates to the field of rotor balancing and correction, and in particular to a glue cleaning mechanism of a glue dispensing head for rotor balancing and correction. Background Art

[0002] The motor rotor is a rotating part in the motor, which is used to cooperate with the motor stator to realize the conversion of electrical energy and mechanical energy. Since the motor rotor is affected by the materials, manufacturing process and assembly process during its manufacturing process, it has an initial imbalance. If the initial imbalance of the motor rotor is too large, it will produce great vibration and noise when rotating at high speed, which not only affects the normal use of the motor, but also greatly shortens the service life of the motor. Based on this, after the motor rotor is processed, workers usually detect and correct the imbalance of the motor rotor to ensure product quality.

[0003] After the rotor balancing test is completed, it needs to be balanced and corrected. The balance correction is achieved by dispensing glue on the unbalanced parts of the rotor with a dispensing head. However, after the dispensing head dispenses glue many times, a lot of glue will remain at the glue outlet, which seriously affects the subsequent dispensing accuracy. Utility Model Content

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] See also Figure 1-2 As shown, there is shown a glue cleaning mechanism of a glue dispensing head for rotor balancing correction, including a base plate 1, two winding rollers 2 rotatable around their own axis lines and arranged on the base plate 1, multiple support rollers 3 rotatable around their own axis lines and arranged on the base plate 1, and a rubber cloth 4 with two ends respectively wound on the two winding rollers 2 and capable of winding through the multiple support rollers 3, the rotation axis of the winding roller 2 is parallel to the rotation axis of the support roller 3, and a rubber cloth groove 5 is formed between the multiple support rollers 3, the rubber cloth 4 includes a first cloth body 41 located in the rubber cloth groove 5, and a second cloth body 42 located outside the rubber cloth groove 5, and the glue cleaning mechanism also includes a cloth pushing component 6 arranged on the base plate 1 for pushing the first cloth body 41 toward the recess in the rubber cloth groove 5.

[0034] The glue wiping groove 5 can accommodate the glue dispensing head. When wiping glue, the glue dispensing head extends into the glue wiping groove 5, and the cloth pushing assembly 6 pushes the first cloth body 41 to contact the glue dispensing head and wipe the glue dispensing head, which can effectively clean the residual glue on the glue dispensing head and ensure the glue dispensing accuracy of the glue dispensing head.

[0035] In this embodiment, the cloth pushing assembly 6 includes two push plates 61 respectively located on both sides of the glue wiping groove 5, and the two push plates 61 are movable in the direction of approaching or moving away from each other. The cloth pushing assembly 6 also includes a first driving module (not shown in the figure) for driving the two push plates 61 to move. The two push plates 61 can approach each other and press the first cloth body 41 against the glue dispensing head, which greatly improves the wiping effect of the first cloth body 41 on the glue dispensing head; after the glue wiping is completed, the two push plates 61 move away from each other and release the glue dispensing head.

[0036] In this embodiment, the substrate 1 is arranged upright, and two winding rollers 2 are respectively arranged on both sides of the lower part of the substrate 1 and their rotation axes extend in the horizontal direction; there are three support rollers 3, and the three support rollers 3 are arranged in a V-shape on the upper part of the substrate 1.

[0037] In this embodiment, an opening 11 is provided on the base plate 1, and two cloth bodies are blocked in the middle of the opening 11. Two push plates 61 are movably arranged at both ends of the opening 11. The opening 11 can movably limit the push plates 61 to ensure the pushing effect of the push plates 61 on the cloth bodies.

The first driving module is used to drive the push racks 62 to rotate. The rotation axis of the push racks 62 is parallel to the rotation axis of the winding roller 2. The other ends of the two push racks 62 are respectively provided with push plates 61, and the extension direction of the push racks 62 is perpendicular to the extension direction of the push plates 61. Among them, the first driving module is a motor, and the two push racks 62 are driven to rotate in opposite directions through the matching structure of the motor and the gear. The specific matching principle is the existing technology and will not be repeated here.

[0039] The glue cleaning mechanism also includes two second driving modules (not shown in the figure) for driving the two winding rollers 2 to rotate respectively.

The two winding rollers 2 can cooperate with each other during their rotation and bring the used first cloth body 41 away from the glue erasing groove 5, bring the unused second cloth body 42 at the rear into the glue erasing groove 5 and form a new first cloth body 41, so that the first cloth body 41 can be automatically replaced, and the continuous cleaning of the glue dispensing head can be achieved, thereby improving the glue cleaning efficiency.

[0040] In this embodiment, three guide rollers 7 are further arranged on the base plate 1. The three guide rollers 7 are rotatable around their own axis and their rotation axes are parallel to the rotation axis of the winding roller 2. The second cloth body 42 is wound around the three guide rollers 7 respectively. One of the three guide rollers 7 is located on one side of the rubber wiping groove 5, and two of them are located on the other side of the rubber wiping groove 5. The three guide rollers 7 can adjust the winding trajectory of the rubber wiping cloth 4 and tighten the rubber wiping cloth 4, thereby improving the wiping quality of the rubber wiping cloth 4.
