FIG. 3 is a schematic structural view of an embodiment of the seal strip installation apparatus of the present application. Fig. 4 is a plan view of the sealing tape attaching apparatus shown in fig. 3. Fig. 5 is a left side view of the sealing tape attaching apparatus shown in fig. 3.

As shown in fig. 3 to 5, the seal strip mounting apparatus includes a conveyor assembly 10, a wheel assembly 20, a cutting assembly 50, and a swing assembly 60. The swing assembly 60 includes a press 61 and a drive assembly 62. The conveyor assembly 10 is used to convey a continuous sealing strip 1. The rotating wheel assembly 20 is used for receiving the sealing strip 1 conveyed by the conveying assembly 10 and rolling the sealing strip 1 to adhere the sealing strip 1 to the object. The cutting assembly 50 is used for cutting the sealing strip 1 when the length of the non-sticking section of the sealing strip is consistent with the length of the preset residual area to be stuck on the object. The sealing tape is continuous and forms an unattached length of sealing tape after the cutting assembly 50 cuts the sealing tape. The non-applied portion of the sealing tape is the portion of the sealing tape between the cutting position and the location where the wheel assembly 20 rolls. The remaining area to be bonded is preset as the portion of the area to be bonded of the object between the bonding end point and the rolling position of the wheel assembly 20. The rolling position of the rotating wheel assembly 20 is the position where the area to be adhered of the object is contacted with the rotating wheel assembly 20 (with the sealing strip 1 in the middle). The strength of the pressing member 61 is greater than that of the weather strip 1. The pressing piece 61 can play a role of structural support, and the posture of the non-sticking section of the sealing strip is controllable in the moving process. The pressing member 61 may be made of steel and has a thin plate shape. The press 61 is located on the upstream side of the wheel assembly 20. The pressing piece 61 is arranged in the extending direction of the sealing strip 1 in the sealing strip non-adhering section. Specifically, the pressure fitting 61 is inserted into the weather strip 1 through the notch 102. The driving assembly 62 is used for driving the pressing piece 61 to move towards the object 2 after the sealing strip 1 is cut by the cutting assembly 50, so that the pressing piece 61 presses and pastes the sealing strip non-sticking section on the preset residual sticking area. The predetermined remaining area to be pasted may be located on a plane.

Fig. 6 to 10 are schematic views each showing different stages of mounting the weather strip 1 to the article 2 using the weather strip mounting apparatus shown in fig. 1. The operation of the weather strip installation apparatus for installing the weather strip 1 to the article 2 will be described with reference to fig. 6 to 10:

fig. 6 is a schematic view at the start of pasting. The sealing tape 1 is conveyed to the wheel assembly 20 through the pressing member 61 after being discharged from the conveying assembly 10. After the robot (not shown) has grasped the object 2, it is brought into abutment against the wheel assembly 20 (with the sealing strip 1 interposed therebetween) and moved along a predetermined path.

Fig. 7 is a schematic view showing a case where the length of the non-application section 1a of the sealing tape is identical to the length of the predetermined remaining area 2a to be applied on the article 2. During the movement of the article 2, the sealing tape 1 is rolled onto the article 2 by the wheel assembly 20 (the roller 24 does not move in the three-dimensional space), and the sealing tape applied section 1b is formed. When the length of the sealing strip non-sticking section 1a is consistent with the length of the preset residual sticking area 2a on the object 2, the sealing strip 1 is cut by the cutting assembly 50, and meanwhile, the rotating wheel assembly 20 and the object 2 stop moving.

Fig. 8 is a schematic view of the pressing member 61 moving the sealing-tape non-application section 1 a. Fig. 9 is a schematic view of the pressing member 61 pressing the sealing tape non-attached section 1a against the preset remaining area to be attached 2 a. After cutting sealing strip 1, drive assembly 62 drives and presses piece 61 and remove towards article 2 for press piece 61 with sealing strip section 1a of not pasting in presetting remaining area 2a of waiting to paste.

Fig. 10 is a schematic view of the wheel assembly 20 rolling onto the article 2 at the end of application. The wheel assembly 20 and the article 2 continue to move, and the wheel assembly 20 rolls the sealing tape 1 (sealing tape non-adhering section 1a) pressed by the pressing member 61. In some use scenes, after the sealing strip 1 is pressed and attached to the preset remaining area to be attached 2a by the pressing and attaching piece 61, the requirement on the attachment strength can be met, and rolling by the rotating wheel assembly 20 is not needed.

In this embodiment, after cutting sealing strip 1, drive assembly 62 drives and presses piece 61 to remove towards article 2 to make and press piece 61 to paste sealing strip non-pasting section 1a in presetting remaining area 2a of waiting to paste. In the pressing and pasting process, the sealing strip 1 cannot deform in the length direction, and the pasting end point position is controllable.

In an application scene, all need paste sealing strip 1 around article 2, promptly, paste the terminal point and paste the coincidence of starting point, use the sealing strip erection equipment of this embodiment, after pasting the completion, can guarantee that the head and the tail end of sealing strip 1 neither can overlap, also can not have the clearance.

Fig. 11 is a schematic view showing the construction of a conveyor in the sealing tape attaching apparatus shown in fig. 1.

As shown in fig. 11, in some embodiments, to facilitate installation of the conveyor, the seal installation apparatus further includes a riser 40. The conveyor assembly 10 is mounted on the riser 40, and positional accuracy of each component in the conveyor assembly 10 can be ensured. The conveying assembly 10 may specifically include three first guide members 11, one second guide member 12, one first driving unit 13, one second guide member 12, one second driving unit 14, two first guide members 11, and one second guide member 12, which are sequentially disposed at intervals.

Fig. 12 is a view in the direction F of the first guide member 11 in the transport apparatus shown in fig. 11.

Please refer to FIG. 12. The first guide member 11 has a guide hole 111 matching the shape and size of the weather strip 1. The weather strip 1 is inserted into the first guide member 11 through a guide hole 111, and the guide hole 111 is used for guiding the movement of the weather strip 1. The sealing tape 1 is conveyed to the second guide 12 after passing through the three first guides 11 in sequence. The second guide member 12 can guide the left and right sides and the upper and lower sides of the weather strip 1. After passing through the second guide 12, the sealing tape 1 is conveyed to the first drive unit 13. The first driving unit 13 includes two conveyor belts 131. The two conveyor belts 131 are driven by motors (not visible in the figure), respectively. One of the conveyor belts 131 can be moved toward or away from the other conveyor belt 131 by the air cylinder 132, thereby allowing the two conveyor belts 131 to grip or release the sealing tape 1. After the two conveyor belts 131 clamp the sealing tape 1, the conveyor belts 131 pull the sealing tape 1 to be conveyed downstream. The sealing tape 1 is conveyed to the second guide 12 and the second drive unit 14 in order after passing through the first drive unit 13. The second driving unit 14 includes a driving pulley 141 and a driven pulley 142. Capstan 141 is driven to rotate by a motor (not visible). The driven wheel 142 is rotatably mounted to a support 143. The support 143 is mounted to the moving end of the cylinder 144. The air cylinder 144 can drive the driven pulley 142 toward or away from the driving pulley 141, thereby causing the driving pulley 141 and the driven pulley 142 to grip the sealing tape 1 and draw the sealing tape 1 to be conveyed downstream. The sealing tape 1 is transported to two first guides 11 and one second guide 12 in turn after passing through the second drive unit 14.

Since the sealing tape 1 has the attaching surface 103a, a protective layer 3 (e.g., release paper) is usually attached to the attaching surface 103a in order to protect the attaching surface 103a during ordinary storage and transportation. When in use, the protective layer 3 needs to be removed. In order to remove the protective layer 3, the transport assembly 10 further comprises three guide rollers 15, a third drive unit 16 and a collecting unit 17. The protective layer 3 passes through three guide rollers 15 and a third driving unit 16 in this order, and is then conveyed to a collecting unit 17. The third drive unit 16 serves to pull the protective layer 3. The collecting unit 17 is used to collect the protective layer 3.

As shown in fig. 11, in some embodiments, cutting assembly 50 includes a cutter 51 and a cylinder 52. The cutter 51 is fixedly arranged at the moving end of the cylinder 52. The air cylinder 52 is operated to drive the cutter 51 to move, thereby cutting the weather strip 1. In the case where the weatherstrip installation apparatus is provided with the riser 40, the cylinder of the air cylinder 52 may be provided on the riser 40.

Fig. 13 is a schematic structural view of the wheel assembly 20 in the weatherstrip mounting apparatus shown in fig. 1. Fig. 14 is a top view of fig. 13.

As shown in fig. 4, 13 and 14, the wheel assembly 20 includes a first mounting seat 21, a second mounting seat 22, a wheel 23, a roller 24, a first pulley 25, a second pulley 26, a conveyor belt 27 and a motor 28. The runner 23 is rotatably disposed on the first mounting seat 21. The roller 24 is rotatably disposed on the second mounting seat 22. The first outer circumferential surface 241 of the roller 24 is disposed opposite to the side surface 232 of the rotating wheel 23, and the first outer circumferential surface 241 and the side surface 232 surround to form the accommodating space 29. Specifically, the roller 24 intersects the axis of the runner 23. The first outer circumferential surface 241 of the roller 24 has a first abutting surface 2411 and a second abutting surface 2412. The first abutting surface 2411 is annularly arranged outside the axis of the roller 23. The second abutting surface 2412 extends from one end of the first abutting surface 2411 outward in the radial direction of the first abutting surface 2411. The side surface 232 of the runner 23 may be a plane perpendicular to the axis of the runner 23, or may be a concave surface recessed away from the first outer peripheral surface 241. In this embodiment, the side 232 is concave. The first abutting surface 2411, the second abutting surface 2412 and the side surface 232 form an accommodating space 29. The receiving space 29 is used for receiving a part of the sealing tape 1, and the second outer circumferential surface 231 of the runner 23 is used for rolling another part of the sealing tape 1. Specifically, the first portion 101 of the sealing strip 1 is located in the accommodating space 29, the second portion 103 of the sealing strip 1 is located outside the accommodating space 29, and the second outer circumferential surface 231 of the runner 23 is used for rolling the second portion 103. The first pulley 25 is coaxially connected with the runner 23. The second pulley 26 is connected to an output shaft of a motor 28. The belt 27 is wound around the first pulley 25 and the second pulley 26. The motor 28 can thereby drive the turning wheel 23 to rotate. When the manipulator drives the object 2 to move relative to the rotating wheel 23, the roller 24 can press the sealing strip 1 against the rotating wheel 23 to limit the position of the sealing strip 1, and the rotating wheel 23 can roll the sealing strip 1.

As shown in fig. 3, in some embodiments, the weatherstrip mounting apparatus further comprises a sensor 30. The sensor 30 is used for detecting the pasting end point on the object 2 during the process of conveying the sealing strip 1 by the conveying assembly 10, and triggering the cutting assembly 50 to cut off the sealing strip 1 when the pasting end point on the object 2 is detected. The length of the sealing strip non-adhering section 1a corresponding to the detection position of the sensor 30 is consistent with the length of the preset residual area to be adhered 2a on the object 2. In the case where the weatherstrip installation apparatus is provided with the riser 40, the sensor 30 may be provided on the riser 40, and the position may be adjusted.

In some application scenarios, the sealing strip 1 pasting starting point coincides with the pasting end point. When the sensor 30 detects the head end of the weatherstrip 1, a signal is sent to a controller (not shown). After receiving the signal sent by the sensor 30, the controller controls the manipulator and the rotating wheel assembly 20 to stop moving, and controls the cutting assembly 50 to act so as to cut the sealing strip 1. After the cutting assembly 50 cuts the sealing strip 1, the controller controls the driving assembly 62 to act, so that the driving assembly 62 drives the pressing piece 61 to move. The cutting assembly 50 is automatically controlled by the sensor 30.

As shown in fig. 8 and 9, in some embodiments, before the sealing tape 1 is cut by the cutting assembly 50, the pressing member 61 and the non-adhering section 1a of the sealing tape are both angled with respect to the predetermined remaining area 2a to be adhered. After the cutting assembly 50 cuts the sealing tape 1, the driving assembly 62 is used for driving the pasting part 61 to swing towards the preset remaining area to be pasted 2 a. The pressing piece 61 presses and pastes the sealing strip non-pasting section 1a to the preset residual area 2a to be pasted in a swinging mode, the action is simple, and the occupied space is small. Specifically, before the cutting assembly 50 cuts the sealing strip 1, the intersection line of the plane of the adhering surface 103a of the non-adhering section 1a of the sealing strip and the plane of the preset remaining area 2a to be adhered is the swing central line of the pressing piece 61. Thus, it is ensured that the joint of the seal-tape non-adhering section 1a and the seal-tape adhering section 1b is not deformed during the swing of the pressing member 61.

As shown in fig. 4, in some embodiments, the weatherstrip mounting apparatus further comprises a barrier assembly 70. The blocking assembly 70 includes a blocking member 71, a rotary cylinder 73, and a telescopic cylinder 72. The blocking member 71 may be a round bar and is fixedly disposed at the telescopic end of the telescopic cylinder 72. The cylinder body of the telescopic cylinder 72 is fixedly arranged at the rotating end of the rotating cylinder 73. The rotating cylinder 73 can drive the stopper 71 to rotate. The telescopic cylinder 72 can drive the stopper 71 to move in the axial direction of the stopper 71. The blocking member 71 can be selectively located on the moving path of the pressing member 61 by the driving of the rotary cylinder 73 and the telescopic cylinder 72, and is configured to abut against a predetermined position of the pressing member 61 when the pressing member 61 moves towards the object 2, so that the end of the pressing member 61 facing away from the rotating wheel assembly 20 approaches the object 2 before the predetermined position of the pressing member 61. The predetermined position is located between the ends of the pressure fitting 61. Specifically, the predetermined position may be the middle of the sticker 61.

Fig. 15 is a schematic structural view of a state in which the stopper 71 is in contact with the pressing member 61. In fig. 15, the stop 71 abuts the middle of the press fit.

As shown in fig. 15, the pressing member 61 has toughness, and the pressing member 61 is deformed into an arc shape under the stop of the stopper 71. The end of the pressure fitting 61 facing away from the wheel assembly 20 is closer to the article 2 than the middle of the pressure fitting 61. The tail end of the sealing tape 1 is located at the end of the caulking member 61 facing away from the wheel assembly 20, whereby the sticking position of the tail end of the sealing tape 1 can be accurately controlled.

After the tail end of the sealing tape 1 is adhered to the article 2, the telescopic cylinder 72 drives the blocking member 71 to move so as to release the blocking of the pressing member 61, thereby enabling the sealing tape 1 located in the middle of the pressing member 61 to be adhered to the article 2. Wherein the provision of the rotary cylinder 73 can avoid the interference of the stopper 71 with the article 2.

Fig. 16 is a schematic view showing the structure of the swing member 60 in the weatherstrip mounting apparatus shown in fig. 1. Fig. 17 is a right side view of fig. 16. Fig. 18 is a top view of fig. 16.

As shown in fig. 16 to 18, the driving assembly 62 includes a base 621, a swing seat 622, a rotating seat 623, and a first driver 627 (see fig. 4). The swing seat 622 is rotatably provided to the base 621 about a first axis L1. The rotating seat 623 is rotatably disposed on the swinging seat 622 about the second axis L2. The first driver 627 is used for driving the swing seat 622 to rotate. The first driver 627 may be a motor. Wherein, the two ends of the pressing piece 61 are respectively connected with the swinging seat 622 and the rotating seat 623.

The first position-limiting portion 624 and the second position-limiting portion 625 are configured to abut against each other to limit the rotation of the rotating seat 623 relative to the swinging seat 622 along the first direction D1.

In a state where the stopper 71 does not block the seal holder 61, the first stopper 624, the second stopper 625, and the elastic member 626 are engaged with each other, and the posture of the rotating seat 623 is stabilized, so that the seal holder 61 is stabilized in shape and the movement of the weather strip 1 can be guided well. When the blocking member 71 blocks the press fitting 61, the rotating seat 623 rotates in a second direction D2 opposite to the first direction D1 with respect to the swinging seat 622, so that the press fitting 61 is deformed into an arc shape. When the blocking member 71 is removed, the rotating seat 623 rotates in the first direction D1 under the elastic force of the elastic member 626, so that the pressing member 61 restores its shape. Thereby, the pressing member 61 is deformed only in the case where the stopper 71 blocks, and the shape of the pressing member 61 is stabilized in a normal state.
