Description
Technical Field
The present disclosure relates to a weather strip application method and apparatus, and more particularly, to a method and apparatus for weather strip seam joining on a flange extending around a vehicle body opening.
Background
In the assembly of a vehicle body, a weather strip (e.g., a weather strip) is typically manually or automatically applied to a flange extending around an opening of a vehicle body (such as a sunroof, a door, a trunk, a hood, and the like).
Referring to fig. 1, the prior art (see, for example, US4620354) has provided methods and apparatus for using a robot to automatically apply a weather strip to a flange extending around an opening in a vehicle body. In this method, first, the weather strip 10 wound on the spool 20 is supplied to the end effector 32, which is manipulated by the robot 34. The end effector 32 unrolls and rolls the weather strip 10, applies the weather strip starting from the starting position until advancing to a stop position a predetermined distance (e.g., 6 inches) from the starting position, then with the end effector 32 in the stop position, the robot arm lifts the unrolled weather strip from the flange, grips and holds the lifted weather strip to sever the weather strip at a point determined by the predetermined distance so that the weather strip applied to the flange can be brought end-to-end at the starting position. Thereafter, end-to-end abutment of the weather strip is achieved by placing the severed end of the weather strip at the flange using the end effector 32 and continuing to roll the weather strip over the seam. This application method is relatively complicated in operation because of the process of lifting the weather strip from the flange for cutting, and also, the quality of the joint is not high enough due to lack of accurate measurement, for example, the seam parts do not abut exactly end to end, but a gap remains or an overlap occurs.
Later, with the application of the sensor, the distance of the rolled position of the weather strip from the end-to-end abutment point (i.e., the starting position) can be detected in real time. As can be described, for example, with reference to fig. 2a, in the prior art method of sealing strip seam joining, under the control of a robot, a sealing strip applicator 110 continuously applies a sealing strip 100 to a flange 160 extending around an opening of a vehicle body, wherein the sealing strip includes a starting end and a contact section that contacts a roller of the sealing strip applicator, an upstream end 102 of the contact section defines a roll-on position B where the roller rolls the sealing strip, and near a downstream end of the contact section there is a seam end 104 to be cut by a cutting device 150 to form a seam abutment a to be joined. The sensor 120 may detect the distance of the upstream end 102 from the seam abutment a (i.e., the distance between the roll position B and the seam abutment a) in real time. When the sensor 120 detects that the distance between the stitching position B and the seam abutment a is equal to the set distance L, the seal strip applicator 110 stops stitching, the cutting device 150 is actuated to cut the seal strip to form the seam end 104, and then the seal strip applicator 110 is re-actuated to stitch the seal strip 100 until the seam end 104 engages the seam abutment a end-to-end. Since the sealing strip is still at least temporarily in a bent state due to contact with the roller of the sealing strip applicator after the cutting step and the seam end 104 of the cut sealing strip is not controlled in any way during the continued rolling of the sealing strip applicator 110, the quality of the rolling of the sealing strip by the sealing strip applicator 110 is difficult to control and the quality of the end-to-end joint cannot be ensured, so that the end-to-end joint at the seam often shows overlapping or still has a gap.
To this end, there is a need for a method and/or apparatus to improve the quality of end-to-end joining at a seam, preferably just to achieve end-to-end abutment.

Detailed Description
Exemplary embodiments will be described in detail below. In the following description, reference is made to the accompanying drawings in which the same reference numerals in different drawings designate the same or similar elements unless otherwise specified. The following exemplary embodiments are intended to be illustrative only and are not intended to limit the scope of the present disclosure.
When applying a sealing strip around a flange extending around an opening of a sunroof, a door, a trunk, a bonnet, etc., it is necessary to abut the head and tail end portions of the sealing strip end to end at the starting position of applying the sealing strip, so that a tightly sealed seam is obtained. The sealing strip comprises a starting end at a starting position and a contact section in contact with a roller of the sealing strip applicator, the contact section having an upstream end and a downstream end, the upstream end of the contact section defining a roll position B at which the roller rolls the sealing strip. That is, the rolling position B corresponds to the intersection point of the projection line of the roller central axis on the plane of the flange and the flange. In this context, upstream means upstream with respect to the rolling direction of the strip applicator, i.e. the part of the strip which has been rolled is upstream and the part of the strip which has not been rolled is downstream. The location of the seal strip starting end is referred to herein as the seam abutment a.
A method for joining a weather strip seam of a vehicle body opening and an apparatus therefor according to the present disclosure will be described below with reference to fig. 2a to 2 f.
Referring to fig. 2a, the seal strip 100 includes an upstream end 102 of the contact section to be rolled by the strip applicator 110 at a rolling position B and a seam end 104 to be joined with the seam abutment a. The adhesive side of the sealing strip is provided with a pressure sensitive adhesive for firm adhesion to the flange. The strip applicator 110 may continuously apply the strip 100 to the flange 160 extending around the body opening under the control of the robot, and the sensor 120 may detect the distance of the upstream end 102 from the seam abutment a (i.e., the distance between the stitching location B and the seam abutment a) in real time. In the method for joining a weather strip seam of a vehicle body opening described herein, when the sensor 120 detects that the distance between the stitching position B and the seam abutment portion a is equal to the set distance L, the weather strip applicator 110 stops stitching, but the cutting device 150 is not actuated to perform weather strip cutting at this time.
Turning now to fig. 2B, when the sensor 120 detects that the distance between the rolled position B and the seam abutment a is equal to the set distance L, the spacer 180 is inserted on the flange 160 at an inserted position C between the rolled position B and the seam abutment a using a spacer insertion and removal device (not shown); the severing device 150 is then actuated to sever the sealing strip near the downstream end of the contact section to form the seam end 104 of the sealing strip. The provision of the spacer 180 serves to avoid the forces generated when cutting the sealing strip inadvertently applying the sealing strip to the flange 160 to form an undesirable bond. The spacer may be made of a teflon material that is not readily adhered to the pressure sensitive adhesive of the weatherstrip. The spacers 180 may be in the form of spacers or spacer rods. The shape and size of the spacer 180 are not limited as long as the anti-adhesion function is performed. The insertion location C of the spacer 180 may be set at any location between the rolled location B and the seam abutment a to provide effective spacing, preferably at a location slightly greater than or equal to the roller radius R of the strip applicator 110 from the rolled location B.
Turning now to fig. 2c, the severed joint end 104 is gripped with the gripper of the pre-positioning device and pulled towards the starting end to pre-position the joint end in a substantially straight state to a pre-positioning position D near the starting end. The predetermined position D is spaced from the seam abutment a by a distance S, which may be dependent on the elasticity and stretchability of the sealing strip to be applied, and provides a margin for ensuring accurate abutment of the seam end 104 against the seam abutment a. The spacing S may be, for example, 4-8 inches, preferably 6 inches. The gripper is a rotatable gripper for gripping the seam end 104 for rotation to the predetermined position D along an arcuate path, which may be at an angle of 70-90 degrees, preferably about 90 degrees. The arcuate path of movement causes the strip to more gradually change from a curved condition to a substantially straight condition. By providing pre-positioning of the seam end 104, the strip is transformed from an original curved state to a substantially flat state, thereby ensuring a more secure and snug bonding of the strip to the flange 160 when the strip 100 is to be rolled by the strip applicator 110, and ensuring more precise end-to-end engagement of the seam end 104 with the seam abutment A, avoiding overlap or gaps. The pre-positioning means may be operated by a corresponding robot.
Turning now to fig. 2d, the spacer 180 is removed by the spacer insertion and removal device and the sealing strip 100 is then peened at the insertion location C by the peened portion of the pre-positioning device (in fig. 2d, the position and direction of the peening is indicated by force F and its arrow direction). Since there is space between the strip 100 and the flange 160 after the spacer 180 is removed, this tapping step means that the strip 100 is positioned to assist in making it more straight than before, thereby pre-smoothing the path of travel of the strip applicator 110. Thus, when the strip applicator 110 is reactivated to roll the strip 100, the adhesion of the strip 100 to the flange 160 will be more firmly and tightly secured and more accurate end-to-end engagement of the seam end 104 with the seam abutment A will be ensured. The spacer insertion and removal devices may be operated by respective robots.
Turning now to FIG. 2e, the strip applicator 110 is reactivated to continue rolling the strip 100 forward. Turning to fig. 2f, the sealing strip applicator 110 continues to roll the sealing strip 100 forward until the seam end 104 engages the seam abutment a end-to-end. Alternatively, it is also possible to roll back and forth multiple times at the seam abutment a, making the seam joint stronger.
Thus, the sealing strip seam joining method of the present disclosure includes the steps of:
and a sealing strip applying step a: applying a sealing strip to the flange 160 of the body opening by means of the sealing strip applicator 110; at the same time, the distance between the rolling position B and the seam abutting portion a is detected by the sensor 120 (detection step);
stopping the rolling step b: when the sensor 120 detects that the distance between the position of rolling B and the seam abutment portion a is equal to the set distance L, the tape applicator 110 stops rolling.
C, cutting the sealing strip: cutting the sealing strip with a cutting device near the downstream end of the contact section to form a seam end 104 of the sealing strip;
an inserting spacer step d arranged between the rolling stopping step b and the sealing strip cutting step c: inserting a spacer 180 on the flange 160 at an insertion location C with a spacer insertion and removal device to prevent inadvertent adhesion caused by the cut-off seal;
pre-positioning the sealing strip: gripping the seam end 104 with a gripper and pulling it towards the starting end to pre-position the seam end in a substantially straight state to a pre-positioning position D near the starting end;
and f, continuing rolling the sealing strip: actuating the strip applicator 110 to continue rolling the strip 100 until the seam end 104 engages the strip seam section a end-to-end;
a step g of removing the spacer, which is arranged between the step e of pre-positioning the sealing strip and the step f of continuously rolling the sealing strip: removing the spacer 180 from the flange 160 using a spacer insertion and removal device; and
a secondary positioning sealing strip step h arranged between the step g of removing the spacer and the step f of continuing rolling the sealing strip: the sealing strip 100 is struck at the insertion location C with the striking portion of the pre-positioning device to make the sealing strip smoother.
Optionally, the method further comprises: after the step c of cutting the sealing strip, the sensor 120 is removed (sensor removal step i).
Optionally, the method further comprises: and (j) a plurality of rolling steps of rolling back and forth a plurality of times at the seam abutment portion a with the seal tape applicator.
Alternatively, the step d of inserting spacers may be provided between the step c of cutting the sealing strip and the step e of pre-positioning the sealing strip, if the sealing strip is cut without causing unintentional adhesion of the sealing strip to the flange, thereby ensuring that unintentional adhesion of the sealing strip to the flange does not occur during the step e of pre-positioning the sealing strip.
In order to perform the above-described method for joining a weather strip seam on a vehicle body opening, the present disclosure provides an apparatus for joining a weather strip seam. The apparatus for joining a seam of a sealing strip includes: a strip applicator 110, which may be robotically controlled, for continuously applying the strip 100 securely to a flange 160 extending around the body opening; the strip includes a start end and a contact section in contact with the roller of the strip applicator 110, the contact section having an upstream end and a downstream end, the upstream end of the contact section defining a roll location D at which the roller rolls the strip; a sensor 120 for detecting the distance between the roll position B and the seam abutment a; a cutting device 150 for cutting the sealing strip near the downstream end of the contact section, thereby forming a seam end 104 of the sealing strip; a pre-positioning device including a gripper for gripping the cut-off seam end 102 to displace the seam end to a pre-positioning position D near the seam abutment a, and a striking section; spacer insertion and removal means for inserting the spacer 180 on the flange 160 in an insertion position C between the seam abutment a and the stitching position B between the stop of the stitching by the strip applicator and the start of the cutting by the cutting means or the start of the cutting by the cutting means and the pre-positioning of the seam end by the gripper, and removing the spacer 180 after said seam end 104 has been placed at or near said pre-positioning position D. The peened portion of the pre-positioning device is used to peen the strip 100 at the insertion location C after removing the spacer 180 so that the strip is flatter than before.
The operation of the various devices of the sealing strip seam joining apparatus may be automated by a robot, which may be pre-programmed and controlled by a control device.
The foregoing is illustrative of the preferred embodiments of the present disclosure and is not to be construed as limiting thereof in any way.
