Description

Technical Field

[0001] This invention relates to the field of automotive assembly technology, and in particular to an assembly and adjustment system for frameless car door glass. Background Technology

[0002] Frameless doors, with their stylish and sporty design, are highly sought after by consumers. Previously limited to one or two high-end models from premium brands, the availability of frameless doors has expanded to include an increasing number of mid-range models, reflecting the growing demand from automakers for this feature.

[0003] Currently, frameless doors lack window frames as a reference for glass installation, and the installation process presents numerous matching points and stringent requirements for vehicle body / door dimensions. Consequently, the industry's frameless door assembly and adjustment equipment still relies primarily on manual clamps. The automation and flexibility of the frameless door installation process are low, resulting in low installation efficiency and difficulty in meeting the growing assembly demands of various automakers. Summary of the Invention

[0004] The purpose of this invention is to provide an assembly and adjustment system for frameless car door glass, which can realize the automated assembly and adjustment of frameless car door glass.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An assembly and adjustment system for frameless vehicle door glass, specifically including a door positioning module for positioning the door sheet metal, a glass positioning module for positioning the glass, and a control module;

[0007] The glass positioning module includes a glass suction cup that can move omnidirectionally in three-dimensional space, and a glass positioning component for defining the position of the glass in the XYZ three-dimensional directions; the glass positioning component is connected to the control module and provides feedback on the status information between the glass and the glass positioning component in the current dimensional direction.

[0008] Based on the status information fed back by the glass positioning component, the control module controls the glass suction cup to adhere to the glass, so that the glass suction cup performs glass positioning in a single dimension of three-dimensional space in sequence. While the glass suction cup is performing glass positioning, the glass suction cup continuously applies force to the glass in the current dimension and the dimension in which the positioning has been performed, so that the glass keeps adhering to the glass positioning component in the current dimension and the dimension in which the positioning has been performed.

[0009] The working principle of this invention is as follows:

[0010] After the door positioning module calibrates the door's position, this assembly system, based on the status information fed back by the glass positioning components, controls the glass suction cup via the control module to adsorb the glass. The glass suction cup then performs glass positioning actions sequentially in any one of the three dimensions (X, Y, and Z) according to a pre-set process sequence, calibrating the glass in each individual dimension. Simultaneously, during the glass positioning calibration process, the glass suction cup continuously applies force to the glass in the current and previously positioned dimensions, causing the glass to press against the glass positioning components in those dimensions, maintaining contact with them. Once the glass is in contact with the glass positioning components in the X, Y, and Z dimensions, the automated assembly and adjustment of the glass and door before installation is complete. Connectors then secure the glass to the door, completing the assembly of the frameless door glass.

[0011] The sequence of dimensional directions for performing positioning calibration can be determined according to process requirements or the design of the glass inspection components. As long as the glass suction cup continuously adheres to the glass during its movement and applies force to the glass in the current dimensional direction and the previously positioned dimensional direction, making the glass conform to the glass positioning components in the current dimensional direction and the previously positioned dimensional direction, it can be ensured that after the glass is positioned and calibrated in the XYZ three dimensions in sequence, the glass tends to the theoretical state position. The position of the glass after assembly with the car door can match the sealing groove of the vehicle body, eliminating the need for additional manpower and time costs to manually adjust the position of the glass after installation, thus improving the glass assembly efficiency.

[0012] In one embodiment, the glass positioning assembly includes an X-axis positioning assembly, a Y-axis positioning assembly, and a Z-axis positioning assembly. Each of the X-axis, Y-axis, and Z-axis positioning assemblies is equipped with a detection switch for detecting the current dimensional direction. The detection switch is connected to a control module and is used to detect the position of the glass in the dimensional direction where the detection switch is located in real time, and to feed back the position status information of the glass to the control module. Based on the information fed back by the detection switch, the control module controls the dimensional direction of movement of the glass suction cup.

[0013] Setting up detection switches facilitates the automation of glass position adjustment in this assembly and adjustment system. If all detection switches in a certain dimension sense the glass, it can be determined that the glass has reached its designated position in that dimension, or is at its theoretical position in that dimension. Subsequently, the control module can execute the glass positioning action in the next dimension. If a detection switch in that dimension does not sense the glass, it can be determined that the glass has not reached its designated position in that dimension. The control module uses a glass suction cup to move the glass towards the location of that detection switch until the switch senses the glass.

[0014] In one embodiment, the X-axis positioning component includes an X-axis positioning wheel and an X-axis detection switch for calibrating the glass's position in the X-axis direction. The wheel surface of the X-axis positioning wheel is in contact with the glass, and the X-axis detection switch is positioned towards the contact direction between the glass and the X-axis positioning wheel. It is used to detect in real time whether the glass is in the X-axis position and to feed back the glass's position information in the X-axis direction to the control module. The control module receives the real-time feedback information from the X-axis detection switch and controls the movement of the glass suction cup in the X-axis direction.

[0015] Furthermore, the door positioning module is equipped with a guide member arranged along the X-axis. The glass positioning module is connected to the guide member and moves back and forth along it. This X-axis positioning component moves with the glass positioning module as a whole, bringing the glass to be installed closer to its X-axis position. Then, a glass suction cup adheres to the glass for fine-tuning, thus shortening the glass adjustment travel distance, reducing the risk of interference during long-distance glass movement, and allowing the glass positioning module to be moved away from the glass after installation, facilitating the removal of the door with the installed glass.

[0016] In one embodiment, the Y-axis positioning assembly includes a Y-axis support member for supporting the glass and a Y-axis power source for driving the Y-axis support member to reciprocate along the Y-axis. The Y-axis power source is connected to a control module, which controls the position of the Y-axis support member in the Y-axis direction via the Y-axis power source. The Y-axis positioning assembly also includes a Y-axis positioning limit block to restrict the travel of the Y-axis support member. When the output end of the Y-axis power source abuts against the Y-axis positioning limit block, the Y-axis support member reaches its support position in the Y-axis direction. The Y-axis positioning limit block can be detached from the Y-axis positioning assembly to allow for replacement with a suitable Y-axis positioning limit block based on the vehicle model requiring adjustment. The Y-axis positioning limit block can also be driven by other power sources to move in the opposite direction to the output end of the Y-axis power source, thereby achieving the purpose of adjusting the travel of the output end of the Y-axis power source based on the vehicle model requiring adjustment. Based on the setting of the Y-direction positioning limit block, the output end of the Y-direction power source directly abuts against the Y-direction positioning limit block in each installation and adjustment operation, which can ensure the consistency of the position of the Y-direction support in each installation and adjustment operation, and avoid the Y-direction power source from wearing out due to long-term use, which would cause the position of the Y-direction support to shift and affect the installation and adjustment of the glass.

[0017] Furthermore, the Y-axis positioning component also includes a Y-axis detection switch that can reciprocate along the Y-axis to calibrate the glass's position in the Y-axis direction. This Y-axis detection switch faces the connection direction between the glass and the Y-axis support, continuously detecting whether the glass is in the correct Y-axis position and feeding back the glass's position information in the Y-axis to the control module. The control module receives the real-time feedback from the Y-axis detection switch and controls the movement of the glass suction cup in the Y-axis direction. The Y-axis positioning component also includes a Y-axis detection limit block to restrict the movement of the Y-axis detection switch. When the Y-axis detection switch reaches the position of the Y-axis detection limit block, it reaches the detection position in the Y-axis direction. By adjusting the position of the Y-axis detection switch using the Y-axis detection limit block, this assembly system can adapt to various vehicle models in the Y-axis direction, expanding its applicability.

[0018] In one embodiment, the Z-axis positioning component includes a Z-axis positioning wheel and a Z-axis detection switch for calibrating the glass's Z-axis positioning position. The wheel surface of the Z-axis positioning wheel is in contact with the glass, and the Z-axis detection switch is positioned towards the contact direction between the glass and the Z-axis positioning wheel. It is used to detect in real time whether the glass is in the Z-axis positioning position and to feed back the glass's Z-axis position information to the control module. The control module receives the real-time feedback information from the Z-axis detection switch and controls the movement of the glass suction cup in the Z-axis direction.

[0019] Furthermore, the Z-axis positioning component includes a Z-axis positioning wheel that drives the Z-axis positioning wheel to rotate in the Y-axis plane.

[0020] The Z-axis power source is connected to the control module, which controls the Z-axis positioning wheel's position in the Z-direction via the Z-axis power source. The Z-axis positioning assembly also includes a positioning component, which comprises a flipping block connected to the output of the Z-axis power source and a positioning block located on the flipping block's flipping path. The flipping block flips synchronously with the Z-axis positioning wheel. When the flipping block engages with the positioning block, the Z-axis positioning wheel reaches its Z-axis positioning position. By adjusting the position of the positioning block on the flipping block's flipping path, the Z-axis positioning wheel can achieve different Z-axis positioning positions, enabling the assembly and adjustment system to adapt to various vehicle models in the Z-direction. Furthermore, by limiting the flipping block's flipping amplitude with the positioning block, the Z-axis positioning wheel's positioning position is consistent each time, preventing wear and tear on the Z-axis power source over time, which could cause the Z-axis positioning wheel to shift position and affect glass assembly and adjustment.

[0021] In one embodiment, the door positioning module includes a bracket, which is provided with a support block for supporting the door, a positioning pin for calibrating the door position, and a clamping assembly for clamping and fixing the door.

[0022] There are multiple support blocks, and the car door is placed on each support block;

[0023] The positioning pin is connected to the control module and is used to detect the position of the door and feed back the position information of the door to the control module;

[0024] The clamping assembly is connected to the control module, which drives the clamping assembly to clamp and fix the door to the support block based on the door position information fed back by the positioning pin.

[0025] The position of the car door is detected by the positioning pins. After all the positioning pins detect the car door, the control module determines that the car door has reached the preset position and controls the clamping assembly to clamp the car door, fixing the car door on the support block. This completes the locking and fixing of the car door in the XYZ three-dimensional directions, effectively ensuring the positional accuracy of the car door.

[0026] Furthermore, the bracket is provided with a movable component that can reciprocate relative to the bracket in the Y direction. The movable component is connected to the positioning pin, which drives the positioning pin to reciprocate in the Y direction to adapt to the door specifications of different car models.

[0027] The advantages of the frameless door glass assembly and adjustment system of the present invention compared with the prior art are as follows:

[0028] (1) This assembly and adjustment system controls the glass suction cup movement through the control module, so that the glass is continuously subjected to forces in multiple dimensions during the assembly and adjustment process, so that the glass always stays in contact with the glass positioning component and does not loosen during the assembly and adjustment process, ensuring that the position of the glass tends to the theoretical state position after the assembly and adjustment is completed.

[0029] (2) This assembly and adjustment system achieves automated adjustment of the glass position through the cooperation of the control module with the X-axis positioning component, Y-axis positioning component and Z-axis positioning component, thereby reducing the labor cost of the overall assembly and adjustment of the frameless door glass.

[0030] (3) This assembly and adjustment system achieves automated calibration of the door position through the cooperation of the control module and the door positioning module, reducing the labor cost of the overall assembly and adjustment of the frameless door glass;

[0031] (4) This assembly and adjustment system adjusts the calibration and detection positions in the Y and Z dimensions by using limit blocks, enabling the door positioning module and glass positioning module to have flexible adjustment functions. This allows the assembly and adjustment system to be applicable to multiple car models, providing equipment support for the flexible production and equipment of frameless door glass.

[0043] Example

[0044] like Figure 1-6 As shown, a preferred embodiment of the present invention provides an assembly and adjustment system for frameless car door glass. The assembly and adjustment system includes a door positioning module 1, a glass positioning module 2, and a control system. The control system can be a PLC system commonly used to control the movement of mechanical components, or other data processing systems, software control systems, etc., that can be used to control the movement of mechanical components. As long as the system can output control signals to the mechanical components after receiving signals transmitted from the outside, and control the movement and state of each mechanical component, it can be used in this assembly and adjustment system.

[0045] like Figure 1-2 As shown, the door positioning module 1 includes a bracket 1a, on which a support block 1b for supporting the door, a positioning pin 1c for calibrating the door position, and a clamping assembly for holding and fixing the door are provided.

[0046] There are multiple support blocks 1b. After the car door is placed into this assembly and adjustment system by the external robotic arm, it is preferentially placed on each support block 1b.

[0047] There are multiple positioning pins 1c, which are connected to the control module to detect the position of the door and feed back the position information of the door to the control module. When all the positioning pins 1c have detected the door and sent a positioning signal to the control module, the control module determines that the door is in the correct position.

[0048] The bracket 1a is provided with multiple movable cylinders 1d that can reciprocate relative to the bracket 1a in the Y direction. Each movable cylinder 1d is connected to each positioning pin 1c as a movable component, driving the positioning pin 1c to reciprocate in the Y direction, thereby adjusting the door position in the Y direction to adapt to the door specifications of different car models.

[0049] The clamping assembly includes multiple clamping cylinders 1e, each of which is connected to the control module. Based on the door position information fed back by the positioning pin 1c, the control module determines that the door is in the correct position and then drives the clamping cylinder 1e to clamp and fix the door on the support block 1b.

[0050] In addition, the bracket 1a is provided with a guide rail 1f arranged along the X direction as a guide component. The glass positioning module 2 is connected to the guide rail 1f as a whole and moves back and forth in the X dimension along the guide axis of the guide rail 1f.

[0051] like Figure 1-6 As shown, the glass positioning module 2 includes a glass suction cup 2a that can move omnidirectionally in three-dimensional space, and a glass positioning component for defining the position of the glass in the XYZ three-dimensional directions. The glass suction cup 2a can be driven by a three-axis cylinder to realize adjustment and movement in the XYZ three-dimensional directions, or it can be driven by a mechanical structure with multiple spatial degrees of freedom, such as an omnidirectional manipulator, to realize adjustment and movement in the XYZ three-dimensional directions.

[0052] In this embodiment, the glass positioning assembly includes multiple X-axis positioning components, multiple Y-axis positioning components, and multiple Z-axis positioning components, wherein,

[0053] like Figure 3 As shown, the X-axis positioning assembly includes an X-axis positioning wheel 2b and an X-axis detection switch 2c for calibrating the glass's position in the X-axis direction. The wheel surface of the X-axis positioning wheel 2b is in contact with the glass, and the X-axis detection switch 2c is positioned towards the contact direction between the glass and the X-axis positioning wheel 2b. It is used to detect in real time whether the glass is in the X-axis position and to feed back the glass's position information in the X-axis direction to the control module. The control module receives the information fed back in real time from the X-axis detection switch 2c and controls the movement of the glass suction cup 2a in the X-axis direction.

[0054] like Figure 4-5 As shown, the Y-axis positioning assembly includes a Y-axis support member 2d for supporting the glass, a Y-axis cylinder 2e for driving the Y-axis support member 2d to reciprocate along the Y-axis, a Y-axis positioning limit block 2f for limiting the travel of the Y-axis support member 2d, a Y-axis detection switch 2g, and a Y-axis detection limit block 2h.

[0055] The Y-direction support member 2d is provided with a support column 2i arranged along the Y direction. The end of the support column 2i is designed with an arc surface for contacting the glass.

[0056] The Y-axis cylinder 2e serves as a Y-axis power source and is connected to the Y-axis support 2d. By extending and retracting the piston rod, it drives the Y-axis support 2d to move in the Y direction, thereby adjusting the position of the Y-axis support 2d in the Y direction. The Y-axis cylinder 2e is also connected to the control module, enabling the control module to send control signals to control the extension and retraction of the piston rod of the Y-axis cylinder 2e, thereby adjusting the position of the Y-axis support 2d.

[0057] The Y-direction positioning limit block 2f is set on the frame composed of the glass positioning module 2 and is located in front of the Y-direction cylinder 2e; after the piston rod of the Y-direction cylinder 2e extends out and abuts against the Y-direction positioning limit block 2f, the Y-direction support member 2d reaches the currently set support position in the Y direction.

[0058] like Figure 5 As shown, the Y-axis detection switch 2g is driven by a conventional power source such as a cylinder or hydraulic cylinder, and moves reciprocally along the Y-axis to calibrate the glass's position in the Y-axis. This Y-axis detection switch 2g faces the connection direction between the glass and the Y-axis support 2d, and detects in real time whether the glass is in the correct Y-axis position, feeding back the glass's position information in the Y-axis to the control module. The control module receives the real-time feedback information from the Y-axis detection switch 2g and controls the movement of the glass suction cup 2a in the Y-axis.

[0059] The Y-direction detection limit block 2h is set on the frame composed of the glass positioning module 2 and is located in front of the movement path of the Y-direction detection switch 2g. When the power source output end that drives the Y-direction detection switch 2g, such as the piston rod of the cylinder, abuts against the Y-direction detection limit block 2h, the Y-direction detection switch 2g reaches the detection position in the Y direction.

[0060] Based on the setting of Y-direction positioning limit block 2f, Y-direction support 2d and Y-direction detection switch 2g can be directly positioned in one go during the current assembly and adjustment operation, ensuring the consistency of the position of Y-direction support 2d and Y-direction detection switch 2g in each assembly and adjustment operation.

[0061] like Figure 6 As shown, the Z-axis positioning assembly includes a Z-axis positioning wheel 2j, a Z-axis detection switch 2k for calibrating the glass's Z-axis positioning position, a Z-axis flipping cylinder 2l for driving the Z-axis positioning wheel 2j to flip in the Y-axis plane, and a positioning assembly, wherein...

[0062] The surface of the Z-axis positioning wheel 2j is in contact with the glass. The Z-axis detection switch 2k is set in the direction of the glass and the Z-axis positioning wheel 2j to detect in real time whether the glass is in the Z-axis position and to feed back the position information of the glass in the Z-axis to the control module. The control module receives the information fed back in real time from the Z-axis detection switch 2k and controls the movement state of the glass suction cup 2a in the Z-axis.

[0063] Z-axis tilting cylinder 2l is connected to the control module as a Z-axis power source. The control module controls the position of Z-axis positioning wheel 2j in the Z-axis direction through Z-axis tilting cylinder 2l.

[0064] The positioning component includes a flipping block 2m connected to the piston rod of the Z-direction flipping cylinder 2l, and a positioning block 2n located on the flipping path of the flipping block 2m. The flipping block 2m flips synchronously with the Z-direction positioning wheel 2j. When the flipping block 2m is attached to the positioning block 2n, the Z-direction positioning wheel 2j reaches the positioning position in the Z direction.

[0065] It should be noted that the Y-direction positioning limit block 2f, the Y-direction detection limit block 2h, and the positioning component are all detachable structures, allowing for the replacement of appropriate limit and positioning structures based on the vehicle model requiring adjustment. The Y-direction positioning limit block 2f, the Y-direction detection limit block 2h, and the positioning component can also be driven by other power sources to move in the opposite direction relative to the object limiting their travel, thereby achieving the purpose of adjustment based on the vehicle model requiring adjustment.

[0066] The working process of the assembly and adjustment system in this embodiment is as follows:

[0067] First, the door and the placed glass enter the assembly system. At this time, the glass positioning module 2 moves away from the door positioning module 1 along the guide rail 1f. The door is placed on each support block 1b, and each support block 1b supports the door simultaneously. At the same time, the positioning pin 1c detects the door position and sends a signal to the control module that the door has reached the current position detected by the positioning pin 1c. If all positioning pins 1c detect the door and send a positioning signal to the control module, the control module determines that the door is in the correct position. The control module drives the clamping cylinder 1e to clamp the door and fix it in the bracket 1a. If any positioning pin 1c fails to detect the door, the control system will control the external clamping mechanism to move the door and adjust its position so that the door is in the correct position.

[0068] Subsequently, the glass positioning module 2 moves along the guide rail 1f, causing the X-axis positioning component to approach the glass. Next, the control module controls the glass suction cup 2a to adhere to the glass, moving it towards the X-axis positioning component until it simultaneously rests against the surfaces of all the X-axis positioning wheels 2b. At this point, if all X-axis detection switches 2c detect the glass, it is determined that the glass is in the X-axis positioning position, and the X-axis detection switches 2c that detect the glass send feedback information about the glass's position in the X-direction to the control module. The control module confirms that the glass is in the X-axis positioning position.

[0069] Then, the control module maintains control over the glass suction cup 2a, causing it to continuously apply a force in the X direction to the glass, keeping it adhered to all the X-direction positioning wheels 2b. Simultaneously, the control module controls the glass suction cup 2a to move in the Z direction, causing the glass to slowly adhere to the wheel surfaces of all the Z-direction positioning wheels 2j. During the Z-direction movement of the glass, the control module maintains control over the glass suction cup 2a, ensuring it continues to apply a force in the X direction, maintaining the tendency for the glass to move in the X direction, thus guaranteeing a tight fit between the glass and the wheel surfaces of the X-direction positioning wheels 2b.

[0070] When all Z-axis detection switches 2k detect the glass, it is determined that the glass is in the Z-axis positioning position, and the Z-axis detection switches 2k that detect the glass send feedback information about the glass's position in the Z-axis to the control module. The control module confirms that the glass is in the Z-axis positioning position. Subsequently, the control module controls the glass suction cup 2a to move in the Y-axis direction, causing the glass to slowly adhere to the curved surfaces of all Y-axis support members 2d. During the movement of the glass in the Y-axis direction, the control module maintains control output to the glass suction cup 2a, ensuring that the glass suction cup 2a maintains force in both the X and Z directions on the glass, thus maintaining the tendency for the glass to move in both directions and ensuring that the glass is tightly fitted to the wheel surfaces of the X-axis positioning wheel 2b and the Z-axis positioning wheel 2j.

[0071] When both Y-axis detection switches 2g and 2k detect the glass, it is determined that the glass is in the correct Y-axis position. The Z-axis detection switch 2k then sends position information of the glass in the Y and Z directions back to the control module. The control module confirms that the glass is in the correct Y-axis position. At this point, the glass is in the correct position in all three dimensions (X, Y, and Z), and the pre-installation position adjustment has been completed. By screwing in bolts or other structural components, the glass is connected and fixed to the door, thus completing the assembly of the frameless door glass.

[0072] It should be noted that the order of the dimensional orientations for glass positioning and calibration can be determined according to process requirements or other design requirements. It is only necessary to ensure that during the movement of the glass, the glass suction cup 2a continuously adsorbs the glass and applies force to the glass in the current dimensional orientation and the dimensional orientation in which the positioning has been performed, so that the glass conforms to the glass positioning components in the current dimensional orientation and the dimensional orientation in which the positioning has been performed.

[0073] In summary, the assembly and adjustment system for frameless car door glass provided by this invention can ensure that after the glass is positioned and calibrated sequentially in the XYZ three-dimensional directions, the glass tends to the theoretical state position. The position of the glass after assembly with the car door can match the sealing groove of the vehicle body. There is no need to invest additional manpower and time costs to manually adjust the position of the glass after installation, thus improving the assembly efficiency of the glass.

[0074] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
