Description

Technical Field

[0001] This application relates to the field of commercial vehicle exterior component installation technology, and in particular to a method for automatically assembling rear window glass. Background Technology

[0002] Currently, in most automotive windshield assemblies, the adhesive application stage has been largely automated, while in traditional windshield installation, glass loading and installation largely rely on semi-automated manual labor.

[0003] In related technologies, a common approach is to install a sealing strip around the rear window glass and then use the sealing strip to attach the glass to the rear sheet metal. This method relies entirely on manual labor, is inefficient, and the sealing strip is affected by factors such as weather, which further reduces assembly efficiency. Alternatively, glass glue can be used to bond the glass to the sheet metal, but manual pre-positioning is required before glass assembly and the pre-positioning must be removed after assembly. This process is cumbersome and cannot achieve full automation. Summary of the Invention

[0004] This application provides a method for automatically assembling rear window glass to solve the problem in related technologies that rear window glass assembly cannot be fully automated and relies on manual labor.

[0005] To achieve the above objectives, a method for automatically assembling a rear window glass is provided, comprising the following steps:

[0006] Install the positioning magnetic clip onto the rear window glass;

[0007] Apply silicone sealant to the side of the rear window glass facing the rear bulkhead sheet metal, and position the silicone sealant on the side of the positioning magnetic clip away from the center of the rear window glass;

[0008] Grab the rear window glass and move it toward the rear panel according to a set trajectory until the distance between the rear window glass and the rear panel is the bonding gap. Then, fix the rear window glass to the rear panel by positioning magnetic buckles.

[0009] Press and hold the rear window for the specified time, then release the rear window.

[0010] In some embodiments, the positioning magnetic buckle includes a first positioning magnetic buckle installed above the rear window glass and a second positioning magnetic buckle installed below the rear window glass;

[0011] The process of fixing the rear window glass to the rear panel using positioning magnetic clips includes the following steps:

[0012] The upper edge of the rear window glass is fixed to the rear panel using the first positioning magnetic buckle;

[0013] The lower edge of the rear window glass is fixed to the rear panel using the second positioning magnetic buckle.

[0014] In some embodiments, the first positioning magnetic buckle includes:

[0015] A first fixing seat is connected to the rear window glass;

[0016] The first magnetic sheet is rotatably connected to the first fixing base and is located on the side of the first fixing base away from the rear window glass;

[0017] Using the first positioning magnetic clip, the upper edge of the rear window glass is fixed to the rear bulkhead sheet metal, including the following steps:

[0018] The first magnetic sheet is attached to the side of the rear panel away from the rear window glass, so that the rear panel is located between the first fixing seat and the first magnetic sheet.

[0019] In some embodiments, the first positioning magnetic buckle further includes a first mounting platform, which is located on the side of the first fixing seat away from the rear window glass;

[0020] The first magnetic sheet includes a first rotating part, which is rotatably connected to the first mounting platform via a first connector.

[0021] In some embodiments, the first connector uses a pin, which is disposed on a first mounting platform and has a first limiting member disposed along the axial direction of the pin;

[0022] The first rotating part of the first magnetic sheet has an opening;

[0023] Installing the positioning magnetic clip onto the rear window glass includes the following steps:

[0024] The opening is limited on the first limiting member.

[0025] In some embodiments, the second positioning magnetic buckle includes:

[0026] The second fixing bracket is connected to the rear window glass;

[0027] The second magnetic piece is rotatably connected to the second fixing base and is located on the side of the second fixing base away from the rear window glass;

[0028] Using the second positioning magnetic clip, the lower edge of the rear window glass is fixed to the rear bulkhead sheet metal, including the following steps:

[0029] The second magnetic sheet is attached to the side of the rear panel away from the rear window glass, so that the rear panel is located between the second fixing seat and the second magnetic sheet.

[0030] In some embodiments, the second mounting bracket has a receiving groove on the side away from the rear window glass;

[0031] The second positioning magnetic buckle also includes a second limiting member, which is slidably disposed in the receiving groove, and the length of the second limiting member is not longer than the depth of the receiving groove. The second limiting member is in slidable contact with the second magnetic sheet.

[0032] Using the second positioning magnetic clip to fix the lower edge of the rear window glass to the rear bulkhead sheet metal, the following steps are also included:

[0033] The second limiting member is pushed into the receiving groove, causing the second limiting member to detach from the second magnetic piece.

[0034] In some embodiments, when applying silicone sealant to the side of the rear window glass facing the rear bulkhead sheet metal, the silicone sealant is continuously applied and has a specified thickness on the rear window glass, and the width of the side of the silicone sealant in contact with the rear window glass is greater than the width of the side away from the rear window glass.

[0035] In some embodiments, the positioning magnetic buckle is adhered to the rear window glass.

[0036] In some embodiments, the following steps are included before the positioning magnetic clip is installed on the rear window glass:

[0037] Clean the installation area of ​​the positioning magnetic buckle.

[0038] The beneficial effects of the technical solution provided in this application include: This application provides an automatic assembly method for rear window glass. By using positioning magnetic buckles to replace the original manual application of adhesive tape, the positioning and fixing of the rear window glass is achieved. Since the rear panel is a metal product, the magnetic buckles can be attracted to the rear panel after the rear window glass is brought close to it. In addition, the pre-applied glass glue bonds the rear window glass to the rear panel. When the rear window glass is pressed towards the rear panel until the glass glue deforms, making the distance between the rear window glass and the rear panel the bonding gap, the positioning magnetic buckles are attracted by the rear panel and flipped to be attracted to the rear panel, fixing the rear window glass to the rear panel, thus achieving the positioning and fixing function. The rear window glass is pre-fixed before the glass glue cures.

[0039] This method allows for fully automated assembly via robots on a closed production line, solving the glass bonding and fixing problem in automated production lines and greatly improving work efficiency. At the same time, it avoids the possibility of workers coming into contact with chemicals, significantly improving the working environment. Therefore, it can solve the problem of the inability to fully automate rear window glass assembly and the reliance on manual labor in related technologies. Attached Figure Description

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] This application provides a method for automatically assembling rear window glass, which can solve the problem in related technologies that the assembly of rear window glass cannot be fully automated and relies on manual labor.

[0055] See Figures 1 to 10 As shown, this application provides a method for automatically assembling a rear window glass, comprising the following steps:

[0056] S1: Combination Figure 1 As shown, install the positioning magnetic buckle 2 onto the rear window glass 1;

[0057] Optionally, multiple positioning magnetic clips 2 are provided on the edge of the rear window glass 1, so that the rear window glass 1 can be bonded and positioned to the rear panel sheet metal 4 by the positioning magnetic clips 2.

[0058] S2: Combination Figure 2 As shown, apply glass glue 3 to the side of the rear window glass 1 facing the rear panel 4, and position the glass glue 3 on the side of the positioning magnetic buckle 2 away from the center of the rear window glass 1.

[0059] Optionally, combined Figure 1 and Figure 2 As shown, the rear window glass 1 is rectangular, and its center is located at the intersection of the two diagonals of the rectangle; combined with Figure 1 and Figure 2 As shown, the positioning magnetic buckle 2 is located at the edge of the rear window glass 1, and the glass glue 3 is between the positioning magnetic buckle 2 and the glass edge of the rectangular rear window glass 1.

[0060] S3: Grab the rear window glass 1 and move the rear window glass 1 to the rear body sheet 4 along the set trajectory until the distance between the rear window glass 1 and the rear body sheet 4 is the bonding gap. Fix the rear window glass 1 and the rear body sheet 4 by the positioning magnetic buckle 2.

[0061] Specifically, the trajectory is set as follows: after aligning the rear window glass 1 with the rear panel 4, the trajectory of the rear window glass 1 moving towards the rear panel 4.

[0062] Furthermore, during the movement of the rear window glass 1 toward the rear sheet metal 4, since the glass adhesive 3 has a certain thickness, when the distance between the rear window glass 1 and the rear sheet metal 4 is not greater than the thickness of the glass adhesive 3 itself, as the rear window glass 1 continues to move toward the rear sheet metal 4, the glass adhesive 3 will be compressed and deformed, and will stop after being compressed to a certain distance. The area of ​​the glass adhesive 3 between the rear window glass 1 and the rear sheet metal 4, as well as the adhesive strength, reach the degree to which the two can be bonded and fixed. This distance is the bonding gap.

[0063] After the distance between the rear window glass 1 and the rear panel sheet 4 reaches the bonding gap, the positioning magnetic buckle 2 is attracted by the rear panel sheet 4 and fixes the rear window glass 1 to the rear panel sheet 4, avoiding the process from continuously holding the rear window glass 1 and reducing production efficiency.

[0064] Optionally, a robotic arm can be used to pick up the rear window glass 1 by means of a suction cup or other device on the robotic arm.

[0065] S4: Press and hold the rear window glass 1 for a specified time, then release the rear window glass 1.

[0066] Optionally, a specified time is ten seconds. After ten seconds, the robotic arm is released, and the process proceeds to the next step. The positioning magnetic buckle 2 positions and fixes the rear window glass 1, allowing the glass adhesive 3 on the rear window glass 1 to adhere to the rear panel sheet metal 4. After the glass adhesive 3 has cured for one hour, the resulting adhesive strength is sufficient to support the vehicle's normal operation after it leaves the production line.

[0067] This application provides an automatic assembly method for rear window glass. By using positioning magnetic buckles 2 to replace the original manual application of adhesive tape, the positioning and fixing of the rear window glass 1 is achieved. Since the rear panel 4 is a metal product, the positioning magnetic buckles 2 can be attracted to the rear panel 4 after the rear window glass 1 is brought close to the rear panel 4. In addition, the pre-applied glass glue 3 is applied, which bonds the rear window glass 1 to the rear panel 4. When the rear window glass 1 is pressed towards the rear panel 4 until the glass glue 3 deforms, making the distance between the rear window glass 1 and the rear panel 4 the bonding gap, the positioning magnetic buckles 2 are attracted by the rear panel 4 and flip up to be attracted to the rear panel 4, fixing the rear window glass 1 to the rear panel 4, thus achieving the positioning and fixing function. The rear window glass 1 is pre-fixed before the glass glue 3 cures.

[0068] This method allows for fully automated assembly via robots on a closed production line, solving the glass bonding and fixing problem in automated production lines and greatly improving work efficiency. At the same time, it avoids the possibility of workers coming into contact with chemicals, significantly improving the working environment. Therefore, it can solve the problem of the inability to fully automate rear window glass assembly and the reliance on manual labor in related technologies.

[0069] In some alternative embodiments, see Figure 1 and Figure 2 As shown, the positioning magnetic buckle 2 includes a first positioning magnetic buckle 5 installed above the rear window glass 1 and a second positioning magnetic buckle 6 installed below the rear window glass 1;

[0070] Specifically, the upper first positioning magnetic buckle 5 corresponds to the upper edge of the rear sheet metal 4, and the lower second positioning magnetic buckle 6 corresponds to the lower edge of the rear sheet metal 4.

[0071] Specifically, fixing the rear window glass 1 to the rear panel sheet metal 4 using the positioning magnetic buckle 2 includes the following steps:

[0072] The upper edge of the rear window glass 1 is fixed to the rear panel sheet metal 4 using the first positioning magnetic buckle 5;

[0073] The lower edge of the rear window glass 1 is fixed to the rear panel sheet metal 4 using the second positioning magnetic buckle 6.

[0074] Optionally, when the distance between the rear window glass 1 and the rear panel 4 is the bonding gap, the first positioning magnetic buckle 5 and the second positioning magnetic buckle 6 will snap the rear window glass 1 onto the rear panel 4, respectively snapping and limiting the rear window glass 1 onto the rear panel 4 at the upper and lower edges to achieve a fixed effect.

[0075] In some alternative embodiments, see Figures 3 to 5 As shown, the first positioning magnetic buckle 5 includes a first fixing base 51 and a first magnetic piece 52, wherein the first fixing base 51 is connected to the rear window glass 1, and the first magnetic piece 52 is rotatably connected to the side of the first fixing base 51 away from the rear window glass 1.

[0076] Using the first positioning magnetic buckle 5, the upper edge of the rear window glass 1 is fixed to the rear panel sheet metal 4, including the following steps:

[0077] Make the first magnetic piece 52 adhere to the side of the rear panel 4 away from the rear window glass 1, so that the rear panel 4 is located between the first fixing seat 51 and the first magnetic piece 52.

[0078] Specifically, the first positioning magnetic buckle 5 has an active state and a dormant state:

[0079] In step S1 above, before the distance between the rear window glass 1 and the rear panel sheet 4 in step S3 becomes the bonding gap, the first magnetic sheet 52 is perpendicular to the rear window glass 1, that is... Figure 3 The hibernation state shown;

[0080] After the distance between the rear window glass 1 and the rear panel 4 is the bonding gap, the first magnetic sheet 52 is attracted by the rear panel 4, changing from its original dormant state (perpendicular to the rear window glass 1) to the activated state, that is, as Figure 4 As shown;

[0081] Specifically, since the first positioning magnetic buckle 5 is used to pre-position the upper edge of the rear window glass 1, it is combined with... Figures 3 to 4 As shown, the first positioning magnetic buckle 5 transitions from a dormant state to an active state, that is, the first magnetic piece 52 moves from... Figure 3 The perpendicular to the rear window glass 1 is converted to Figure 4 Parallel to the rear window glass 1.

[0082] In some alternative embodiments, see Figures 3 to 5 As shown, the first positioning magnetic buckle 5 also includes a first mounting platform 53, specifically, the first mounting platform 53 is located on the side of the first fixing seat 51 away from the rear window glass 1;

[0083] Furthermore, the first magnetic sheet 52 includes a first rotating part 521, and a first connecting member 54 is provided on the first mounting platform 53. The first rotating part 521 is rotatably connected to the first mounting platform 53 through the first connecting member 54.

[0084] Specifically, the first mounting platform 53 protrudes from the surface of the first fixing base 51, in conjunction with... Figure 3 and Figure 4 As shown, there are two first mounting platforms 53, and the first connector 54 is located between the two first mounting platforms 53 so that after the second magnetic sheet 62 is flipped, the position of the rear sheet metal 4 is left between the second magnetic sheet 62 and the second fixed seat 61.

[0085] Combination Figure 9 As shown, when the first positioning magnetic buckle 5 is in the activated state, the rear sheet metal 4 is positioned between the first magnetic piece 52 and the rear window glass 1, so as to secure the rear window glass 1 as shown. Figure 11 The positioning clip shown is attached to the rear sheet metal 4.

[0086] In some alternative embodiments, see Figures 3 to 5 As shown, the first connector 54 uses a pin; specifically, the pin is mounted on the first mounting platform 53 and engages with... Figure 5 As shown, a first limiting member 541 is provided along the axial direction of the pin shaft.

[0087] Correspondingly, the first rotating part 521 of the first magnetic sheet 52 has an opening 523, which is used for... Figure 5 and Figure 10 As shown, installing the first positioning magnetic buckle 5 onto the rear window glass 1 includes the following steps:

[0088] The opening 523 is limited on the first limiting member 541.

[0089] Specifically, the first magnetic sheet 52 further includes a first magnetic part 522, which is connected to the first rotating part 521, in combination. Figure 5 and Figure 10 As shown, the first rotating part 521 is not completely closed, but has an opening 523. One end of the opening 523 is limited on the first limiting member 541, so that the first magnetic part 522 is held as... Figure 3 and Figure 10 As shown, the glass is perpendicular to the rear window 1 and will not fall due to gravity.

[0090] Optionally, the first limiting member 541 is a long strip or block protruding from the pin shaft. Specifically, the pin shaft is fixedly set between the two first mounting platforms 53 and will not rotate. The first rotating part 521 is sleeved on the pin shaft, and one end of the opening 523 is limited on the first limiting member 541, restricting the first magnetic part 522 from flipping downward.

[0091] It should be noted that, without affecting the fixing process between the rear window glass 1 and the rear panel 4, and provided that the first magnetic piece 52 can pass through the notch of the rear panel 4, the first magnetic piece 52 may not be perpendicular to the rear window glass 1 (the angle between it and the rear window glass 1 is 90°), for example, it may be at an angle of 85° to the rear window glass 1. This can be achieved by changing the position of the first limiting member 541.

[0092] In some alternative embodiments, see Figures 6 to 7 As shown, the second positioning magnetic buckle 6 includes a second fixing base 61 and a second magnetic piece 62, wherein the second fixing base 61 is connected to the rear window glass 1, and the second magnetic piece 62 is rotatably connected to the side of the second fixing base 61 away from the rear window glass 1.

[0093] Specifically, the lower edge of the rear window glass 1 is fixed to the rear panel sheet metal 4 using the second positioning magnetic buckle 6, including the following steps:

[0094] Make the second magnetic piece 62 adhere to the side of the rear panel 4 away from the rear window glass 1, so that the rear panel 4 is located between the second fixing seat 61 and the second magnetic piece 62.

[0095] Specifically, the second positioning magnetic buckle 6 has an active state and a dormant state:

[0096] In step S1 above, before the distance between the rear window glass 1 and the rear panel sheet 4 in step S3 becomes the bonding gap, the second magnetic sheet 62 is perpendicular to the rear window glass 1, i.e. Figure 6 The hibernation state shown;

[0097] After the distance between the rear window glass 1 and the rear panel 4 is the bonding gap, the second magnetic sheet 62 is attracted by the rear panel 4, changing from its original dormant state (perpendicular to the rear window glass 1) to the activated state, that is, as Figure 7 As shown;

[0098] Specifically, since the second positioning magnetic buckle 6 is used to pre-position the upper edge of the rear window glass 1, it is combined with... Figures 6 to 7 As shown, the second positioning magnetic buckle 6 transitions from the dormant state to the active state, that is, the second magnetic piece 62 moves from... Figure 6 The perpendicular to the rear window glass 1 is converted to Figure 7 Parallel to the rear window glass 1.

[0099] In some alternative embodiments, see Figures 6 to 8 As shown, the second fixing seat 61 has a receiving groove 611 on the side away from the rear window glass 1;

[0100] Correspondingly, the second positioning magnetic buckle 6 also includes a second limiting member 65, combined with Figure 6 and Figure 8 As shown, the second limiting member 65 is slidably disposed in the receiving groove 611;

[0101] Specifically, the length of the second limiting member 65 is not longer than the depth of the receiving groove 611, and the second limiting member 65 slides in contact with the second magnetic sheet 62 to support the second magnetic sheet 62 so that it will not flip down due to gravity.

[0102] Specifically, using the second positioning magnetic buckle 6 to fix the lower edge of the rear window glass 1 to the rear panel sheet metal 4, the method also includes the following steps:

[0103] The second limiting member 65 is pushed into the receiving groove 611, so that the second limiting member 65 is disengaged from the second magnetic piece 62.

[0104] The rear panel 4 is located between the second magnetic sheet 62 and the rear window glass 1, so as to position and snap the rear window glass 1 onto the rear panel 4.

[0105] By combining the first positioning magnetic buckle 5 and the second positioning magnetic buckle 6, the upper and lower edges of the rear window glass 1 can be fixed to the rear panel sheet metal 4, achieving the purpose of pre-fixing the rear window glass before the glass glue cures.

[0106] In some alternative embodiments, see Figure 6 and Figure 7As shown, the second positioning magnetic buckle 6 also includes a second mounting platform 63, specifically, the second mounting platform 63 is located on the side of the second fixing seat 61 away from the rear window glass 1;

[0107] Furthermore, the second magnetic sheet 62 includes a second rotating part 621, and a second connecting member 64 is provided on the second mounting platform 63. The second rotating part 621 is rotatably connected to the second mounting platform 63 through the second connecting member 64.

[0108] Specifically, the second mounting platform 63 is provided to protrude from the surface of the second fixing seat 61 so that after the second magnetic sheet 62 is flipped, a position of the rear sheet metal 4 is left between the second magnetic sheet 62 and the second fixing seat 61.

[0109] Optionally, combined Figures 6 to 8 As shown, there are two second mounting platforms 63, a second connector 64 is disposed between the two second connectors 64, and a second rotating part 621 is sleeved on the second connector 64;

[0110] Furthermore, the second magnetic sheet 62 also includes a second magnetic part 622, which is connected to the second rotating part 621. The second limiting member 65 is disposed below the second magnetic part 622 to support the second magnetic part 622 so that it will not flip downward due to gravity when the rear window glass 1 moves to the rear panel 4.

[0111] When the distance between the rear window glass 1 and the rear panel 4 reaches the bonding gap, the second magnetic part 622 is attracted by the rear panel 4, and combined with its own gravity, pushes the second limiting part 65 supported below it into the receiving groove 611. The second magnetic piece 62 loses its support, flips downward, and positions the rear window glass 1 on the rear panel 4.

[0112] Optionally, both the second fixing base 61 and the second limiting member 65 are made of plastic, so as not to affect the second magnetic sheet 62.

[0113] In some alternative embodiments, see Figure 9 and Figure 11 As shown, Figures 9 to 11 This diagram illustrates the change in silicone sealant 3 from its initial contact with the rear panel 4 to its compression and bonding gap. Specifically, when applying silicone sealant 3 to the side of the rear window glass 1 facing the rear panel 4, silicone sealant 3 is... Figure 2 The glass sealant 3 is continuously arranged as shown and has a specified thickness on the rear window glass 1. The width of the side of the sealant 3 that contacts the rear window glass 1 is greater than the width of the side that is away from the rear window glass 1.

[0114] This application provides an embodiment, in conjunction with Figure 9 As shown:

[0115] Figure 9 and Figure 11 A cross-sectional view is given at the junction of the glass glue 3, the first positioning magnetic buckle 5, and the rear sheet metal 4. Figure 9 This is a view showing the glass adhesive 3 just coming into contact with the rear sheet metal 4. Figure 11 The view shows the glass glue 3 being compressed so that the distance between the rear window glass 1 and the rear panel sheet metal 4 reaches the bonding gap. It can be seen that the cross-section of the glass glue 3 is trapezoidal, and the lower base of the trapezoid is the side that is in contact with the rear window glass 1.

[0116] Preferably, the trapezoid is an isosceles trapezoid; before compression, the lower base of the isosceles trapezoid is 8mm, the upper base is 2mm, and the height is 10mm; after compression, the lower base of the isosceles trapezoid is 10mm, the upper base is 5mm, and the height is 5mm; the values ​​of the upper and lower bases of the compressed glass glue 3 increase while the height decreases, which increases the area of ​​the adhesive between the rear window glass 1 and the rear panel sheet metal 4, that is, increases the bonding area between the two and improves the bonding strength. The 5mm height of the deformed glass glue 3 is the value of the bonding gap in this embodiment.

[0117] In this embodiment, the preferred method is as follows: Figure 2 The continuous glass glue 3 shown is evenly applied to the edge of the rear window glass 1 so that the deformed glass glue 3 does not overflow the rear panel 4 or the rear window glass 1; or the application range and method of the glass glue 3 can be changed if there is sufficient space or strength.

[0118] In some optional embodiments, the positioning magnetic buckle 2 is adhered to the rear window glass 1. Specifically, the first fixing seat 51 of the first positioning magnetic buckle 5 is adhered to the rear window glass 1, and the second fixing seat 61 of the second positioning magnetic buckle 6 is adhered to the rear window glass 1. Optionally, polyurethane adhesive can be used.

[0119] In some alternative embodiments, the following steps are included before the positioning magnetic clip 2 is installed onto the rear window glass 1:

[0120] Clean the installation location of the positioning magnetic buckle 2.

[0121] Specifically, the positioning magnetic buckle 2 is a permanent part of the vehicle and does not need to be disassembled. The entire operation can be carried out on a closed production line and the assembly is completed automatically by robots. Therefore, it is necessary to clean the installation position before installing the positioning magnetic buckle 2, which can also enhance the connection strength between the positioning magnetic buckle 2 and the rear window glass 1.

[0122] In some alternative embodiments, see Figure 1 and Figure 2As shown, there are five first positioning magnetic buckles 5 on the upper edge of the rear window glass 1 and five second positioning magnetic buckles 6 on the lower edge of the rear window glass 1. The first positioning magnetic buckles 5 and the second positioning magnetic buckles 6 are set in correspondence to achieve vertical symmetry. Through the adsorption between the magnets, the rear window glass 1 is firmly clamped to the rear panel sheet metal 4.

[0123] Multiple positioning magnetic buckles 2, respectively set on the upper and lower edges of the rear window glass 1, can complete basic clamping and positioning.
