Description

Technical Field

[0001] The present application relates to the technical field of vehicle assembly, and in particular to a frameless vehicle door glass assembly tool and an assembly method. Background Art

[0002] As people's requirements for vehicle safety, comfort and reliability are getting higher and higher, the assembly of doors and glass, as important accessories of vehicle bodies, is a key research focus of the automotive industry. The assembly quality of car doors and glass has an important impact on the noise and sealing of the car. For car framed doors, guide grooves and sealing pads are generally provided on the car frame to make up for the assembly error between the glass and the framed door. As for the assembly technical scheme of frameless door glass, since there is no structure on the upper part of the frameless door to limit and guide the glass, the assembly quality of the glass and the frameless door of the car is particularly important.

[0003] In the related art, since frameless doors have no window frames as the installation reference for the glass, a positioning frame is required to assemble and adjust the glass. However, after the positioning frame is released, the glass will rebound, affecting the positioning accuracy of the window glass. In addition, most related arts use the glass itself as the tooling reference. Since there are fluctuations in positioning accuracy on the door sheet metal and the door clamp, for example, the frameless door sheet metal will mostly have a pitch angle deviation on the door clamp, resulting in poor stability in the assembly accuracy of the glass after assembly. Summary of the invention

[0004] In view of this, an embodiment of the present application provides a frameless door glass assembly tool and an assembly method, which can improve the assembly accuracy and stability of the frameless door glass.

[0005] In a first aspect, an embodiment of the present application provides a frameless door glass assembly tool, which includes a glass clamp assembly, a door clamp, and a connection assembly. The glass clamp assembly is used to limit the position of the glass; the door clamp is used to limit the position of the frameless door; the connection assembly includes a hinge, which is used to hinge the glass clamp assembly and the door clamp together so that the glass clamp assembly can rotate relative to the door clamp.

[0006] Specifically, the glass clamp assembly is used to limit the glass, and the door clamp is used to limit the frameless door of the car. The position of the glass and the frameless door of the car can be adjusted by the glass clamp and the door clamp respectively, so that the position of the glass and the frameless door of the car can be roughly matched, and then the position of the glass on the glass clamp assembly can be fine-tuned to complete the assembly of the glass and the frameless door of the car. Among them, when the frameless door sheet metal is limited on the door clamp by means of the door clamp, the plane where the door sheet metal is located will inevitably deviate from the theoretical plane where the door sheet metal is located, that is, the plane where the door sheet metal is located and the theoretical plane where the door sheet metal is located are not on the same plane, and the two form a certain angle, which can be called the door pitch angle in this application. For example, if the door sheet metal is theoretically limited on the door clamp, it is desired that the plane where the door sheet metal is located is perpendicular to the horizontal plane, and it is inevitable that the door clamp will have a limiting error on the door sheet metal, or the door clamp will have external force impact interference during the assembly process, causing the plane where the door sheet metal is located to have an angle with the vertical direction, that is, the actual situation is that the plane where the upper door sheet metal is located is not perpendicular to the horizontal plane, but has a certain pitch angle, which requires consideration of the absorption demand for the pitch angle of the frameless door sheet metal on the door clamp.

[0007] Since the glass clamp assembly and the door clamp are hinged together by the hinge in the connection assembly in the present application, the glass clamp assembly can be rotated relative to the door clamp. In this way, when the frameless door sheet metal has a pitch angle, the glass clamp assembly can be adjusted relative to the door clamp. The glass on the glass clamp assembly can be rotated by a certain angle relative to the frameless door sheet metal. For example, the rotation angle of the glass clamp assembly is slightly larger than the pitch angle of the door sheet metal, so that the extended surface of the glass matches the plane where the door sheet metal is located. Such a design can take into account the demand for absorbing the pitch angle of the door sheet metal clamped on the door clamp, thereby improving the assembly accuracy of the frameless door glass assembly tooling. In addition, since the pitch angle of the frameless door sheet metal may be different each time the glass and the frameless door of the car are assembled, the angle of the glass on the glass clamp assembly will be different accordingly. Since this design takes into account the demand for absorbing the pitch angle of the door sheet metal clamped on the door clamp, it can adapt to a variety of different pitch angles of the door sheet metal, thereby improving the stability during assembly.

[0008] Among them, there is no limitation on the way to realize the limit position of the frameless door glass by the glass clamp assembly. For example, a limit column can be set on the glass clamp assembly to limit the glass. When the glass abuts against the limit column, the glass can be limited. A plate-shaped positioning structure can also be set to limit the glass. A concave structure can also be set to limit the glass. The groove of the concave structure is set corresponding to the extension direction of the glass. When the glass abuts against the groove of the concave structure, the glass is limited. Here, there is no limitation on the limit position of the frameless door of the car. For example, a positioning pin can be set on the door clamp to limit the frameless door of the car. The limit position of the frameless door of the car can also be achieved by setting a magnetic suction structure or a clamping structure. In addition, the present application does not limit the relative positions of the glass clamp assembly and the door clamp. For example, the door clamp can be hinged at the bottom of the glass clamp assembly, or the door clamp as a whole can be fixed in position and the glass clamp assembly can be hinged at the side of the door clamp. This ensures that the glass and the frameless door do not interfere with or collide with each other during the adjustment of their relative positions before assembly is completed.

[0009] In a possible implementation of the present application, the glass clamp assembly includes a glass clamp and a mounting frame, the glass clamp is arranged on the mounting frame, the door clamp is arranged below the glass clamp, and the mounting frame is hinged to the door clamp through a hinge, so that the mounting frame drives the glass clamp to rotate relative to the door clamp. There are many forms in which the glass clamp is arranged on the mounting frame, such as the glass clamp can be connected to the mounting frame by a fastener, the glass clamp can be connected to the mounting frame by welding, or the glass clamp and the mounting frame can be formed in a sliding connection so that the glass clamp moves relative to the mounting frame on the support surface formed by the mounting frame. Here, the setting of the mounting frame can support the glass clamp, and when the glass clamp and the mounting frame are slidably connected, the glass clamp can be moved relative to the support surface formed by them, so as to increase the adaptability of the frameless door glass assembly tool.

[0010] In a possible implementation of the present application, the hinge point between the mounting frame and the door clamp is located below the glass clamp. With this arrangement, when the mounting frame drives the glass clamp disposed thereon to rotate, it is not easy for the glass on the glass clamp to interfere with the frameless door on the door clamp and cause a collision.

[0011] In a possible implementation of the present application, the plane where the door sheet metal of the frameless door is located has a rotation angle relative to the clamping surface of the door clamp, and the projections of the rotation point of the frameless door and the hinge point between the mounting frame and the door clamp in the direction perpendicular to the plane where the door sheet metal of the frameless door is located all fall on the door clamp. Here, it should be noted that the clamping surface of the door clamp can refer to a plane perpendicular to the horizontal plane, or it can refer to a plane with a pre-set angle with the horizontal plane, and there is no specific limitation; wherein, when the clamping surface of the door clamp is a plane perpendicular to the horizontal plane, the rotation angle of the plane where the door sheet metal of the frameless door is located relative to the clamping surface of the door clamp is also the door pitch angle mentioned above. The pitch angle rotation point of the frameless door glass assembly tooling equipment is also the hinge point between the mounting frame and the door clamp, and the projections of the rotation point of the frameless door and the hinge point between the mounting frame and the door clamp in the direction perpendicular to the plane where the door sheet metal of the frameless door is located all fall on the door clamp. This design allows the pitch angle rotation point of the frameless door glass assembly tooling equipment to fall within the range of the door pitch angle rotation point. Compared with designing the equipment pitch rotation point above the glass clamp or between the glass clamp and the door clamp, it is convenient to adjust the rotation angle of the glass relative to the frameless door, so as to better absorb the pitch angle of the frameless door and improve the assembly accuracy.

[0012] In a possible implementation of the present application, the connection assembly also includes a support mechanism, the support mechanism includes a driving member, one end of the driving member is fixed on the door fixture, and the other end is connected to the hinge member in a transmission manner, and the driving member is used to drive the mounting frame to make an arc motion relative to the door fixture, so that the mounting frame drives the glass fixture to make an arc motion relative to the door fixture, and the plane where the motion trajectory of the mounting frame is located is perpendicular to the plane where the door sheet metal of the frameless door is located. Here, the addition of the driving member, compared with the direct manual operation of the mounting frame to make an arc motion relative to the door fixture, facilitates the automatic control of the action response of the driving member, and can make the mounting frame rotate a preset angle relative to the door fixture, so as to automatically adjust the glass on the glass fixture to rotate a preset pitch angle relative to the frameless door on the door fixture, thereby absorbing the pitch angle deviation of the frameless door. In addition, the setting of the driving member can also play a supporting role for the glass fixture assembly and the door fixture, so that the glass fixture assembly is more stable during the rotation process relative to the door fixture.

[0013] In a possible implementation of the present application, the hinged member includes an hinged seat, a rotating shaft and a connecting member, the hinged seat is fixed on the door clamp, the rotating shaft is connected to the hinged seat, one end of the connecting member is rotationally connected to the rotating shaft, and the other end is connected to the mounting frame, and the output end of the driving member is transmission-connected to the connecting member, and is used to drive the connecting member to rotate relative to the door clamp, so that the connecting member drives the mounting frame to make an arc motion relative to the door clamp. Here, the setting that the hinged seat is fixed on the door clamp can make the door clamp and the hinged seat jointly bear the supporting effect on the glass clamp assembly. In addition, the rotating shaft is connected to the mounting frame through a connecting member, rather than the rotating shaft being directly connected to the mounting frame. On the one hand, the glass clamp assembly on the mounting frame can be staggered with the door clamp, so as to avoid interference and collision between the mounting frame and the door clamp during the rotation of the mounting frame relative to the door clamp. On the other hand, it can increase the matching degree between the glass and the frameless door, which is convenient for improving the assembly accuracy.

[0014] In a possible implementation of the present application, the driving member includes a cylinder, the cylinder includes a body and a telescopic shaft, the telescopic shaft can be extended or retracted along the body, the body is fixedly connected to the door clamp, the telescopic shaft is the output end of the driving member, and is used for transmission connection with the connecting member; there are at least two connecting components, the axial directions of the telescopic shafts of the cylinders in each connecting component are arranged in parallel, and the axis of the telescopic shaft of each cylinder is parallel to the plane where the motion trajectory of the mounting frame is located. Among them, when the telescopic shaft telescopes along its axis, it can drive the mounting frame to rotate a certain angle relative to the door clamp, and the rotation angle of the mounting frame can be adjusted by controlling the telescopic length of the telescopic shaft. In addition, preferably, the connecting components can be set to two, and the cylinders in the two connecting components are respectively arranged at the two ends of the mounting frame relative to each other, so that the support stability of the glass clamp can be improved.

[0015] In a possible implementation of the present application, the distance from the hinge point to the plane where the door sheet metal on the door clamp is located is smaller than the distance from the hinge point to the extension surface of the glass on the glass clamp. With such a configuration, when the mounting frame drives the glass clamp on it to rotate, the entire glass clamp will not interfere with or collide with the door clamp, and the glass extension surface on the glass clamp can be in the same plane as the frameless door of the door clamp during the rotation of the glass clamp, which facilitates the assembly of the glass.

[0016] In a possible implementation of the present application, the frameless door glass assembly tool further includes a control component, and the glass clamp, the door clamp and the cylinder are all electrically connected to the control component, wherein the control component is used to: control the position limit of the door clamp on the frameless door; control the position limit of the glass clamp on the glass; control the extension or retraction of the telescopic shaft of the cylinder; obtain the angle deviation value when the frameless door is on the door clamp, and can be used to obtain the relative position information of the glass and the frameless door and confirm whether the glass is assembled properly. Specifically, the angle deviation value when the frameless door is on the door clamp can be obtained by the control component, that is, the pitch angle of the frameless door, and then the control component is used to control the cylinder to respond, so that the mounting frame drives the glass on the glass clamp thereon to rotate a certain angle, so that it can absorb the pitch angle of the door so that the glass and the frameless door are approximately located on the same plane, and finally the relative position information of the glass and the frameless door is obtained and the glass assembly is confirmed whether it is assembled properly. If it is not qualified, the control component is continued to control the cylinder to respond until the assembly accuracy requirements are met.

[0017] In a second aspect, the present application provides a method for assembling frameless door glass, which uses any frameless door glass assembly tool described in the first aspect to assemble a frameless door and glass, and includes the following steps: obtaining an angle deviation value of a frameless door limit on a door clamp; rotating the glass clamp assembly relative to the door clamp assembly by a preset angle, wherein the preset angle is greater than the angle deviation value; wherein the angle deviation value is an angle between a plane where a door sheet metal of the frameless door is located and a vertical direction, and the rotation direction of the glass clamp assembly is consistent with the deflection direction of the frameless door. Specifically, considering that a frameless door may have a pitch angle on the door fixture, that is, the plane where the door sheet metal of the actual frameless door is located has a certain angle with the plane where the door sheet metal of the theoretical frameless door is located, that is, there is an angle deviation value when the frameless door limit is located on the door fixture. In order to absorb the problem of low assembly accuracy caused by the angle deviation, the glass fixture assembly can be rotated by a preset angle relative to the door fixture assembly, and the preset angle is greater than the angle deviation value. In this way, the angle deviation value can be absorbed during the assembly process to meet the assembly accuracy requirements. In this way, since the frameless door glass assembly method adopts the frameless door glass assembly tooling in the first aspect, it has the same effect, that is, the accuracy and assembly stability of the frameless door glass assembly can be improved.

[0034] With the emergence of innovative models in the automobile manufacturing industry and users' increasingly higher requirements for innovative models, the automobile manufacturing industry is required to continuously improve automobile assembly technology. Frameless glass door cars with luxurious, fashionable and dynamic features are increasingly favored by users and are attracting the domestic coupe market. Compared with ordinary framed doors, the installation technology of frameless doors has no restraining parts for the glass at the position corresponding to the glass at the upper end of the frameless door, and the sealing between the body and the outside here also depends on the sealing between the glass and the body. Therefore, the installation accuracy of frameless glass doors is relatively high and the technology is complex. As a result, most cars have many shortcomings such as easy jamming and loud noise inside the window due to the failure of frameless glass door installation technology to meet the requirements.

[0035] The automobile frameless door glass assembly tool is a device used to assemble the automobile frameless door glass to the automobile frameless door. For the conventional structure of the existing frameless door glass assembly tool, refer to Figure 1 and Figure 3 , mainly composed of transition seat 01, cross roller bearing 02, main machine mounting plate 03, four-bar assembly 04, universal hinge seat 05, glass positioning mechanism 06 of glass dispensing equipment and door positioning mechanism 07; among which, the equipment pitch angle rotation point is provided by four-bar assembly 04 and universal hinge seat 05, and the universal hinge seat 05 and four-bar assembly 04. Among them, the four-bar assembly 04 is as follows Figure 2 As shown, the four-bar assembly 04 includes a vertical plate 041 fixedly connected to the main engine mounting plate 03, a main cylinder base 042, a main cylinder 043, an axle pin 044, a main arm 045, a secondary arm 046, a forearm upper shaft 047 and a porous bearing seat 048. Specifically, the main cylinder 043 is fixedly connected to the main cylinder base 042, the main cylinder base 042 is fixedly connected to the vertical plate 041, and the telescopic shaft 3211b of the main cylinder 043 is away from One end of the main cylinder 043 is hinged to the main arm 045 through the axle pin 044, so that when the telescopic shaft of the main cylinder 043 is telescopically moved, the main arm 045 and the auxiliary arm 046 hinged thereto are driven to swing on a plane perpendicular to the axial direction of the axle pin 044, thereby driving the universal hinge seat 05 under the forearm upper shaft 047 connected to one end of the main arm 045 to swing, wherein the universal hinge seat is connected to the forearm upper shaft 047 through a porous bearing seat 048.

[0036] In addition, in the existing assembly technology, refer to Figure 1 and Figure 3, the automobile frameless door glass assembly tool is pre-set at a certain angle, the door positioning mechanism 07 is set according to the angle of the corresponding car body of the automobile frameless door, and the glass positioning mechanism 06 and the door positioning mechanism 07 are set above the door positioning mechanism 07 corresponding to the angle of the glass and the automobile frameless door, so that the automobile frameless door and glass can be conveniently assembled. Among them, the glass positioning mechanism 06 and the door positioning mechanism 07 are both installed on the entire installation base plate 08, and there is no hinged structure between the glass positioning mechanism 06 and the door positioning mechanism 07, and the glass positioning mechanism 06 cannot rotate relative to the door positioning mechanism 07. The entire glass positioning mechanism 06 and the door positioning mechanism 07 are fixedly connected to form a whole, except that the glass positioning mechanism 06 can slide relative to the installation base plate 08 and the door positioning mechanism 07 can slide relative to the installation base plate 08. The entire glass positioning mechanism 06 and the door positioning mechanism 07 can be integrated into one and rotate relative to the transition seat 01 through the four-bar assembly 04 and the universal joint seat 05, that is, the pitch rotation point of the equipment is located above the glass positioning mechanism 06.

[0037] That is, the frameless door glass assembly tooling equipment in the prior art can only rotate the glass positioning mechanism 06 and the door positioning mechanism 07 on the entire mounting base 08, but cannot realize the rotation of the glass positioning mechanism 06 relative to the door positioning mechanism 07. The pitch angle rotation point of the equipment itself is provided by the four-bar assembly 04 and the universal joint seat 05, so that the pitch angle of the frameless door glass assembly equipment does not match the design value of the door pitch angle, and the turning point of the frameless door glass assembly tooling equipment is set high, that is, the existing equipment does not take into account the absorption of the pitch angle accuracy deviation of the frameless door on the door fixture 2 in the tooling equipment, resulting in poor glass accuracy stability after the equipment is assembled.

[0038] To solve the above problems, refer to Figure 4 , Figure 5 and Figure 6 , the embodiment of the present application provides a tool for assembling glass for a frameless door of an automobile. Starting from the difference between the pitch angle rotation point of the frameless door glass subassembly equipment and the pitch angle rotation point of the door, the pitch angle rotation point of the frameless door glass subassembly equipment is designed to be within the range of the pitch angle rotation point of the door while increasing the pitch angle design angle of the equipment, thereby reducing the difference and improving the glass assembly accuracy and assembly stability. The frameless door glass assembly tool includes a glass clamp assembly 1, a door clamp 2, and a connection assembly 3. Among them, the glass clamp assembly 1 is used to limit the glass; the door clamp 2 is used to limit the frameless door; the connection assembly 3 includes a hinge 31, and the hinge 31 is used to hinge the glass clamp assembly 1 and the door clamp 2 together so that the glass clamp assembly 1 can rotate relative to the door clamp 2.

[0039] Specifically, the glass clamp assembly 1 is used to limit the position of the glass, and the door clamp 2 is used to limit the position of the frameless door of the car. The positions of the glass and the frameless door of the car can be adjusted by the glass clamp assembly 1 and the door clamp 2 respectively, so that the positions of the glass and the frameless door of the car can be roughly matched, and then by fine-tuning the position of the glass on the glass clamp assembly 1, the glass and the frameless door of the car can be assembled. Among them, when the frameless door sheet metal is limited on the door clamp 2, the plane where the door sheet metal is located will inevitably deviate from the theoretical plane where the door sheet metal is located, that is, the plane where the door sheet metal is located and the theoretical plane where the door sheet metal is located are not on the same plane, and the two form a certain angle, which can be called the door pitch angle in this application. For example, if theoretically the door sheet metal is limited on the door clamp 2, it is desired to make the plane where the door sheet metal is located perpendicular to the horizontal plane, and the door clamp 2 will inevitably have a limiting error on the door sheet metal, or the door clamp 2 will have external force impact interference during the assembly process, causing the plane where the door sheet metal is located to have an angle with the vertical direction, that is, the actual situation is that the plane where the upper door sheet metal is located is not perpendicular to the horizontal plane, but has a certain pitch angle, which requires consideration of the absorption demand for the pitch angle of the frameless door sheet metal on the door clamp 2.

[0040] Since the glass clamp assembly 1 and the door clamp 2 are hinged together by the hinge 31 in the connection assembly 3 in the present application, the glass clamp assembly 1 can be rotated relative to the door clamp 2. In this way, when the frameless door sheet metal has a pitch angle, the glass clamp assembly 1 can be adjusted relative to the door clamp 2 by adjusting the rotation angle, that is, the glass on the glass clamp assembly 1 can be rotated relative to the frameless door sheet metal by a certain angle. For example, the rotation angle of the glass clamp assembly 1 is slightly greater than the pitch angle of the door sheet metal, so that the extended surface of the glass is aligned with the plane where the door sheet metal is located. Matching, that is, through such a design, the demand for absorbing the pitch angle of the door sheet metal clamped on the door clamp 2 can be taken into account, thereby improving the assembly accuracy of the frameless door glass assembly tooling. In addition, since the pitch angle of the frameless door sheet metal may be different each time the glass and the frameless door of the car are assembled, the angle deviation of the glass on the glass clamp assembly 1 is also different accordingly. Since this design takes into account the demand for absorbing the pitch angle of the door sheet metal clamped on the door clamp 2, it can adapt to a variety of different pitch angles of the door sheet metal, thereby improving the stability during assembly.

[0041] Among them, there is no limitation on the way to realize the positioning of the frameless door glass by the glass clamp assembly 1. For example, a positioning column can be set on the glass clamp assembly 1 to limit the glass. When the glass abuts against the limiting column, the glass can be limited. A plate-shaped positioning structure can also be set to limit the glass. A concave structure can also be set to limit the glass. The groove of the concave structure is set corresponding to the extension direction of the glass. When the glass abuts against the groove of the concave structure, the glass is limited. Here, there is no limitation on the positioning method of the frameless door of the car. For example, a positioning pin can be set on the door clamp 2 to achieve the positioning of the frameless door of the car. The positioning of the frameless door of the car can also be achieved by setting a magnetic suction structure or a clamping structure. In addition, the present application does not limit the relative positions of the glass clamp assembly 1 and the door clamp 2. For example, the door clamp 2 can be hinged at the bottom of the glass clamp assembly 1, or the door clamp 2 can be fixed in an overall position and the glass clamp assembly 1 is hinged at the side of the door clamp 2. This ensures that the glass and the frameless door will not interfere with or collide with each other during the adjustment of their relative positions before assembly is completed.

[0042] It should be noted that unless otherwise specified in this application, Figure 5 , the description is made by taking the case where the door clamp 2 is hinged below the glass clamp assembly 1 as an example.

[0043] In some embodiments, reference Figure 4 , Figure 5 and Figure 6The glass clamp assembly 1 includes a glass clamp 11 and a mounting frame 12. The glass clamp 11 is arranged on the mounting frame 12, and the door clamp 2 is arranged below the glass clamp 11. The mounting frame 12 is hinged to the door clamp 2 through a hinge 31, so that the mounting frame 12 drives the glass clamp 11 to rotate relative to the door clamp 2. The mounting frame 12 is used to provide a mounting base for the glass clamp 11, and to enhance the connection strength with the door clamp 2 hinged below it. Here, preferably, the mounting frame 12 is set to a frame type. The frame type mounting frame 12 can facilitate the installation of other accessories. For example, other accessories can be connected to the frame of the mounting frame 12 through a clamp, or a slide rail can be set on the frame to enable a sliding connection between the glass clamp 11 and the mounting frame 12. There are many ways to set the glass clamp 11 on the mounting frame 12, such as connecting the glass clamp 11 to the mounting frame 12 by fasteners, connecting the glass clamp 11 to the mounting frame 12 by welding, or forming a sliding connection between the glass clamp 11 and the mounting frame 12 so that the glass clamp 11 moves relative to the mounting frame 12 on the support surface formed by the mounting frame 12. Here, the installation of the mounting frame 12 can support the glass clamp 11, and when the glass clamp 11 and the mounting frame 12 are slidably connected, the glass clamp 11 can move relative to the support surface formed by them, so as to increase the adaptability of the frameless door glass assembly tool.

[0044] In some embodiments, reference Figure 4 , Figure 5 and Figure 6 , the hinge point between the mounting frame 12 and the door clamp 2 is located below the glass clamp 11. In the embodiment of the present application, unless otherwise specified, the hinge point between the mounting frame 12 and the door clamp 2 is the pitch angle rotation point of the frameless door glass assembly tooling equipment. Here, when the hinge point between the mounting frame 12 and the door clamp 2 is located below the glass clamp 11, when the mounting frame 12 drives the glass clamp 11 disposed thereon to rotate, it is not easy for the glass on the glass clamp 11 to interfere with the frameless door on the door clamp 2 and cause a collision.

[0045] In some embodiments, reference Figure 4 , Figure 5 and Figure 6, the plane where the door sheet metal of the frameless door is located has a rotation angle relative to the clamping surface of the door clamp 2, and the projections of the rotation point of the frameless door and the hinge point between the mounting frame 12 and the door clamp 2 in the direction perpendicular to the plane where the door sheet metal of the frameless door is located all fall on the door clamp 2. Here, it should be noted that the clamping surface of the door clamp 2 can refer to a plane perpendicular to the horizontal plane, or can refer to a plane with a pre-set angle with the horizontal plane, and there is no specific limitation; among which, when the clamping surface of the door clamp 2 is a plane perpendicular to the horizontal plane, the rotation angle of the plane where the door sheet metal of the frameless door is located relative to the clamping surface of the door clamp 2 is also the door pitch angle mentioned above. The pitch angle rotation point of the frameless door glass assembly tooling equipment is also the hinge point between the mounting frame 12 and the door clamp 2. The projections of the rotation point of the frameless door and the hinge point between the mounting frame 12 and the door clamp 2 in the plane direction perpendicular to the door sheet metal of the frameless door all fall on the door clamp 2. This design allows the pitch angle rotation point of the frameless door glass assembly tooling equipment to fall within the range of the door pitch angle rotation point. Compared with designing the equipment pitch rotation point above the glass clamp 11 or between the glass clamp 11 and the door clamp 2, it is convenient to adjust the rotation angle of the glass relative to the frameless door, so as to better absorb the pitch angle of the frameless door and improve the assembly accuracy.

[0046] In some embodiments, reference Figure 4 , Figure 5 and Figure 6 The connection assembly 3 also includes a support mechanism 32, which includes a driving member 321. One end of the driving member 321 is fixed on the door fixture 2, and the other end is connected to the hinge 31. The driving member 321 is used to drive the mounting frame 12 to make an arc motion relative to the door fixture 2, so that the mounting frame 12 drives the glass fixture 11 to make an arc motion relative to the door fixture 2, and the plane where the motion trajectory of the mounting frame 12 is located is perpendicular to the plane where the door sheet metal of the frameless door is located. Here, the addition of the driving member 321 is convenient for automatically controlling the action response of the driving member 321, compared with directly manually operating the mounting frame 12 to make an arc motion relative to the door fixture 2, so that the mounting frame 12 can rotate a preset angle relative to the door fixture 2, so as to automatically adjust the glass on the glass fixture 11 to rotate a preset pitch angle relative to the frameless door on the door fixture 2, thereby absorbing the pitch angle deviation of the frameless door. In addition, the arrangement of the driving member 321 can also play a supporting role for the glass clamp 11 assembly 1 and the door clamp 2 , so that the glass clamp 11 assembly 1 is more stable during the rotation process relative to the door clamp 2 .

[0047] The specific form of the driving member 321 is not limited. For example, the driving member 321 may be a cylinder 3211, a continuously variable electric cylinder, an oil cylinder, etc. Preferably, in some embodiments, Figure 6The driving member 321 adopts a cylinder 3211 with low cost and large power output. The cylinder 3211 includes a body and a telescopic shaft 3211b, the telescopic shaft 3211b can be extended or retracted along the body, the body is fixedly connected to the door fixture 2, the telescopic shaft 3211b is the output end of the driving member 321, and is used for transmission connection with the connecting member 313; there are at least two connecting components 3, and the axial directions of the telescopic shaft 3211b of the cylinder 3211 in each connecting component 3 are arranged in parallel, and the axis of the telescopic shaft 3211b of each cylinder 3211 is parallel to the plane where the motion trajectory of the mounting frame 12 is located. Among them, the body of the cylinder 3211 can be fixed on the door clamp 2 through the tail seat of the cylinder 3211, and the telescopic shaft 3211b of the cylinder 3211 is connected to the connecting member 313 as the output end of the driving member 321. For example, the axial direction of the telescopic shaft 3211b of the cylinder 3211 has a certain angle with the supporting surface of the mounting frame 12 for the glass. When the telescopic shaft 3211b moves along its axis, it can drive the mounting frame 12 to rotate a certain angle relative to the door clamp 2. The rotation angle of the mounting frame 12 can be adjusted by controlling the telescopic length of the telescopic shaft 3211b. In addition, preferably, the connecting assembly 3 can be set to two, and the cylinders 3211 in the two connecting assemblies 3 are respectively arranged at the two ends of the mounting frame 12, so that the support stability of the glass clamp 11 can be improved.

[0048] Reference Figure 4 , Figure 5 and Figure 6 The hinged member 31 includes a hinged seat 311, a rotating shaft 312 and a connecting member 313. The hinged seat 311 is fixed on the vehicle door fixture 2. The rotating shaft 312 is connected to the hinged seat 311. One end of the connecting member 313 is rotatably connected to the rotating shaft 312, and the other end is connected to the mounting frame 12. The output end of the driving member 321 is transmission-connected to the connecting member 313, and is used to drive the connecting member 313 to rotate relative to the vehicle door fixture 2, so that the connecting member 313 drives the mounting frame 12 to make an arc motion relative to the vehicle door fixture 2. Here, the setting that the hinged seat 311 is fixed on the vehicle door fixture 2 can make the vehicle door fixture 2 and the hinged seat 311 jointly bear the supporting function of the glass fixture assembly 1. In addition, the rotating shaft 312 is connected to the mounting frame 12 via the connecting piece 313, rather than the rotating shaft 312 being directly connected to the mounting frame 12. On the one hand, the glass clamp assembly 1 on the mounting frame 12 can be staggered with the door clamp 2 to avoid interference and collision between the mounting frame 12 and the door clamp 2 during rotation relative to the door clamp 2. On the other hand, the matching degree between the glass and the frameless door can be increased, thereby facilitating improved assembly accuracy.

[0049] In some embodiments, reference Figure 4 , Figure 5 and Figure 6, the distance from the hinge point to the plane where the door sheet metal on the door clamp 2 is located is less than the distance from the hinge point to the extension surface of the glass on the glass clamp 11. With such a configuration, when the mounting frame 12 drives the glass clamp 11 thereon to rotate, the entire glass clamp 11 will not interfere with or collide with the door clamp 2, and it is easy to make the glass extension surface on the glass clamp 11 be in the same plane with the frameless door of the door clamp 2 during the rotation of the glass clamp 11, which is convenient for the assembly of the glass.

[0050] In some embodiments, reference Figure 4 , Figure 5 and Figure 6 The frameless door glass assembly tool also includes a control component, and the glass clamp 11, the door clamp 2 and the cylinder 3211 are all electrically connected to the control component, wherein the control component is used to: control the limit of the frameless door by the door clamp 2; control the limit of the glass by the glass clamp 11; control the extension or retraction of the telescopic shaft 3211b of the cylinder 3211; obtain the angle deviation value of the frameless door on the door clamp 2, and can be used to obtain the relative position information of the glass and the frameless door and confirm whether the assembly of the glass is qualified. Specifically, for example, a positioning reference and a positioning module are provided on the door fixture. The positioning module on the door fixture 2 can be adjusted by the control component to make the reference and the door of the frameless door cooperate and position, so as to limit the relative position of the frameless door relative to the door fixture 2 to be fixed; the glass fixture 11 has a glass positioning module for limiting in multiple directions. The multiple glass positioning modules can be switched to a non-positioning position first, so as to place and adjust the position of the glass on the glass positioning module, and then the position of the multiple glass positioning modules can be controlled by the control component, so that the glass is pre-installed on the glass lifting mechanism in the frameless door. Most of the pre-installed glass is not yet It can meet the assembly accuracy requirements. At this time, the control component can be used to obtain the angular deviation value of the frameless door on the door clamp 2, that is, the pitch angle of the frameless door. Then, the control component is used to control the cylinder 3211 to respond, so that the mounting frame 12 drives the glass on the glass clamp 11 thereon to rotate a certain angle, so that it can absorb the pitch angle of the door so that the glass and the frameless door are approximately located on the same plane. Finally, the relative position information of the glass and the frameless door is obtained and it is confirmed whether the assembly of the glass is qualified. If not, the control component is continued to control the cylinder 3211 to respond until the assembly accuracy requirements are met.

[0051] The present application also provides a frameless door glass assembly method, referring to Figure 7 and Figure 8 The method for assembling the frameless door glass of the vehicle comprises the following steps:

[0052] Step S100: obtaining an angle deviation value of the frameless door limit on the door fixture 2;

[0053] Among them, in step S100, it is considered that the frameless door may have a pitch angle on the door fixture 2, that is, the plane where the door sheet metal of the actual frameless door is located has a certain angle with the plane where the door sheet metal of the theoretical frameless door is located, that is, there is an angle deviation value when the frameless door limit is located on the door fixture 2. In addition, in some embodiments, the control component also includes a detection component and a controller, and the detection component can be used to detect the angle deviation value of the frameless door limit located on the door fixture 2, and transmit the angle deviation value to the controller, thereby obtaining the angle deviation value of the frameless door limit located on the door fixture 2.

[0054] In addition, in some embodiments, before step S100, step S001 is also included: matching the position of the glass with the position of the frameless door. Specifically, first confirm that the frameless door installation enters the preparation operation area, and at the same time confirm that the frameless door glass assembly tooling equipment is in a normal state; then after the frameless door enters the operation area, control the door sheet metal positioning mechanism on the door clamp 2 to advance toward the door sheet metal, so that the positioning pin on the tooling is pushed into the positioning hole of the door sheet metal, and push the door clamp 2 tightly so that the clamping surface of the door clamp 2 is close to the sheet metal inside the door. When the detection component on the assembly tooling detects that the door sheet metal is tightly matched with the door clamp 2, the control component starts to control the glass clamp 11 to move relative to the door sheet metal, such as by adjusting the guide component on the glass clamp 11 to adjust the relative position of the glass and the door, so that the position of the glass matches the position of the frameless door. Here, it should be noted that the matching of the position of the glass and the position of the frameless door refers to an approximate match, and can also refer to a pre-assembly process before precise assembly. Subsequently, it is usually necessary to rely on the guide components on the glass clamp 11, the glass positioning module in multiple directions, the glass suction cup and other tools to fine-tune the position of the glass, and subsequently, the angle deviation of the vehicle door must be taken into account to adjust the rotation angle of the mounting frame 12 relative to the door clamp 2, so as to finally meet the assembly accuracy requirements.

[0055] Step S200: The glass clamp assembly 1 is rotated relative to the door clamp 2 by a preset angle, and the preset angle is greater than the angle deviation value; wherein the angle deviation value is the angle between the plane where the door sheet metal of the frameless door is located and the vertical direction, and the rotation direction of the glass clamp 11 assembly 1 is consistent with the deflection direction of the frameless door. Specifically, in step S200, in order to absorb the problem of low assembly accuracy caused by the angle deviation, the glass clamp 11 assembly 1 can be rotated relative to the door clamp 2 assembly by a preset angle, and the preset angle is greater than the angle deviation value, so that the angle deviation value can be absorbed during the assembly process to meet the assembly accuracy requirements.

[0056] Continuing, after step S200, step S300 is also included, judging whether the glass assembly is qualified based on the relative position information of the frameless door and the glass. Among them, even if the glass clamp assembly 1 is rotated by a preset angle relative to the door clamp assembly 2 through step S200, and the preset angle is greater than the angle deviation value, so that the glass and the frameless door can be assembled to meet the assembly accuracy requirements, after the glass clamp 113 releases the constraint on the glass, the glass will more or less produce displacement or angle deviation, and it is difficult to ensure that the glass stays in the theoretical position. Therefore, a qualified range will be set during the assembly process. For example, after the glass clamp assembly 1 is rotated by a preset angle relative to the door clamp 2, and after the glass is released, the angle between the glass extension surface and the plane where the door sheet metal of the frameless door is located is unlikely to be zero, and there will be a smaller angle, which needs to be satisfied within a preset qualified range. The actual angle position information between the assembled glass extension surface and the surface where the door sheet metal of the frameless door is located is compared with the preset qualified range to confirm whether the assembly is qualified.
