Detailed Description

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.

The utility model provides an automatic deviation correcting device, referring to fig. 1 to 4, which comprises a supporting component 10, a deviation correcting component 20 and a resetting component 3, wherein the supporting component 10 is provided with a first concave cavity part 11 for a component to be transported to pass through, and the deviation correcting component 20 is provided with a second concave cavity part 21 for the component to be transported to pass through. The first pocket 11 and the second pocket 21 are arranged in the transport direction of the component to be transported. At least part of the deviation rectifying assembly 20 is swingably arranged with respect to the supporting assembly 10 to have an initial position in which the second cavity portion 21 is opposed to the first cavity portion 11; the reset device 3 is connected with the deviation rectifying assembly 20 so that the deviation rectifying assembly 20 returns to the initial position under the action of the reset device 3 after swinging.

When the component to be transported moves to the automatic deviation correcting device, the component passes through the first concave cavity part 11 formed by the supporting component 10 and then passes through the second concave cavity part 21 formed by the deviation correcting component 20. The first cavity portion 11 and the second cavity portion 21 are formed at an initial position relative to each other so that the movement locus of the member to be transported is a straight line. When the component to be transported deviates from the linear motion track, the component to be transported drives the deviation rectifying assembly 20 to deflect, so that the friction force between the component to be transported and the deviation rectifying assembly 20 is slowed down. And, the component 20 of rectifying can resume to the initial position under the effect of reset part 3, and then prevent to rectify by force and easily wearing and tearing wait the transportation part, and adjust to the initial position by oneself through reset part 3 and realize waiting the rectifying of transportation part, solved the problem that is difficult to rectify to the sticky tape of transportation among the prior art.

Specifically, the component to be transported is an adhesive tape. The initial position of the correction assembly 20 is: when the deviation rectifying assembly 20 is in the initial position, the center line of the second concave cavity portion 21 in the transport direction coincides with the center line of the first concave cavity portion 11 in the transport direction. I.e. the centre line of the cross-section in figure 2 and the centre line of the cross-section in figure 3 are parallel to each other.

However, due to friction and other factors generated during the transportation of the to-be-transported component, when the second cavity portion 21 is not at the initial position relative to the first cavity portion 11, and when the center line of the first cavity portion 11 is not coincident with the center line of the second cavity portion 21, the deviation correcting assembly 20 is pulled in time due to the pulling force of the resetting component 3, so that the second cavity portion 21 returns to the initial position relative to the first cavity portion 11. Thereby, the movement locus of the movement of the member to be transported becomes a straight line again.
