Description

Technical Field

[0001] The invention relates to a tooling for a car sunroof, in particular to a device for measuring and shaping the glass of a car sunroof. Background Art

[0002] The car sunroof is installed on the roof, which can effectively circulate air in the car and increase the entry of fresh air. At the same time, the car sunroof can also broaden the field of vision and meet the needs of mobile photography and videography.

[0003] As an important sub-component of the car sunroof, the contour of the upper surface of the glass assembly is particularly important. Excessive contour tolerance will not only affect the assembly of the sunroof assembly, but also cause the theoretical height of the glass and the body to be inconsistent at the part where the sunroof assembly matches the body after installation, which will then cause quality defects such as poor appearance. After the glass is hemmed, especially during the process from the glass assembly being ejected from the mold to the complete cooling and solidification of the PU, the contour of the upper surface of the glass assembly will change greatly. Therefore, the glass assembly needs to be measured and shaped before being installed on the sunroof. The glass of the car sunroof generally needs to be processed through the glass hemming process and shaping process.

[0004] Glass edging process: A piece of ordinary sunroof tempered glass cannot be fixed on the sunroof frame except by bonding because the outer surface of the glass is smooth and there is no special structure. And because there is no special structure, it is not easy to match the glass with the surrounding parts. And even though it is tempered glass, even if it is fixed by bonding, it still cannot meet the light requirements of the car sunroof. Therefore, the tempered glass and the embedded iron parts around the glass are edged (plasticized) with polyurethane (PU). That is: iron parts are placed around the inner surface of the tempered glass and put into the mold. The process of using melted polyurethane to fix the iron parts and the tempered glass together. The current edging process has the following defects: in the process from the demolding of the glass assembly to the complete cooling and solidification of the PU, the contour of the upper surface of the glass assembly will change greatly during the cooling process of the polyurethane from the high-temperature liquid to the normal temperature solid. The contour of the glass is not satisfied (not matching the outer surface of the car body). It can only be solved by plastic surgery.

[0005] The shaping process is to perform contour detection on the solidified edge-wrapped glass assembly → fix the glass → press the glass at a specific position based on the contour value and computer calculation → slightly deform the curvature of the iron parts inside the polyurethane → thereby meeting the glass contour requirements.

[0006] At present, the equipment for measuring and shaping glass generally has a layout where the glass placement area is raised on all sides and sunken in the middle, so it is difficult for workers to place the glass in the middle bottom of the equipment without scratching it. This equipment has high labor intensity and the glass can easily cause harm to people. Therefore, it is very beneficial to invent a device for measuring and shaping automobile sunroof glass.

[0035] The working principle of the present invention is as follows:

[0036] Because the glass placement area of ​​the entire device is convex on all sides and concave in the middle, it is difficult for workers to place the glass in the middle bottom of the device without scratching it. When the present invention is in the storage state, it is in the middle bottom of the device. During operation, the glass electric suction cup is lifted by the glass lifting suction cup mechanism (3), and the worker places the glass on the electric suction cup, and the electric suction cup sucks the glass. The glass is lowered and placed on the Z-axis support mechanism.

[0037] The X-direction positioning clamping mechanism, through the cooperation between the cylinder and the position sensor + position sensing sheet, slides the glass top block along the slide rail direction and holds the glass against the X-direction positioning mechanism on the opposite side, thereby fixing the X-direction of the glass.

[0038] The Y-axis centering positioning mechanism slides the glass top block along the slide rail through the cooperation of the cylinder and the position sensor + position sensor sheet, and keeps the left and right sliding synchronously, so that the glass can be fixed in the center between the left and right glass top blocks.

[0039] When the Z-direction clamping mechanism is not in use, the rotating arm is basically vertically upward. When support is needed, the rotating arm is rotated by the rotating cylinder (21) to make the rotating arm horizontal and the supporting surface horizontal. When support is needed, the rotating arm is rotated by the rotating cylinder (21) to make the rotating arm horizontal and the supporting surface horizontal.

[0040] The working procedures and steps of the present invention are as follows:

[0041] 1 Preparation process: Glass lifting suction cup mechanism rises

[0042] 2 Workers place the plastic-coated glass on the glass lifting suction cup mechanism

[0043] 3 The suction cup sucks the glass, the glass lifting suction cup mechanism descends, and the glass is placed on the Z-axis support mechanism and

[0044] 4 The suction cup is released, and the glass lifting suction cup mechanism returns to the storage position

[0045] 5. Glass positioning process: The X-direction positioning clamping mechanism pushes the glass toward the X-direction positioning mechanism (i.e., the glass is pushed toward the X direction)

[0046] 6 The Y-axis centering positioning mechanism centers the glass in the Y axis.

[0047] 7 The Z-direction clamping mechanism presses the glass onto the support surface of the Z-direction support mechanism (i.e., the glass is pressed to death in the Z direction)

[0048] 8. Contour: Inspection process

[0049] The first round of front / rear / left / right contour measuring mechanism is raised from the storage position to the measuring position to perform contour detection on the relevant measuring points on the glass.

[0050] 9After measurement is completed, the contour measurement mechanism returns to the storage position

[0051] 10 The computer collects the measured data and calculates the contour of the glass at each position at this moment.

[0052] 11 If the glass contour is qualified, skip the following steps until step 2512 If the glass contour is unqualified, the direction / force / point required to press the glass is obtained through the formula customized by the program

[0053] 13 Shaping process: If the glass is arched relative to the theoretical position, the upper shaping mechanism will press the upper surface of the glass at six specific points based on the computer's calculation results.

[0054] 14 If the glass is sunken relative to the theoretical position, the front / rear lower shaping mechanism will push up the lower surface of the glass at six specific points based on the computer calculation results.

[0055] 15. The second round of contour detection process:

[0056] The front / rear / left / right contour measuring mechanism is raised from the storage position to the measuring position to perform contour detection on the relevant measuring points on the glass

[0057] 16 After the measurement is completed, the contour measurement mechanism returns to the storage position

[0058] 17 If the glass contour is qualified, skip the following steps until step 2518 If the glass contour is unqualified, the direction / force / point required to press the glass is obtained through the formula customized by the program

[0059] 19 Plastic surgery process:

[0060] If the glass is arched relative to the theoretical position, the upper shaping mechanism will press the upper surface of the glass at six specific points based on the computer's calculation results.

[0061] 20 If the glass is sunken relative to the theoretical position, the front / rear lower shaping mechanism will push up the lower surface of the glass at six specific points based on the computer calculation results.

[0062] 21 The third round of contour detection process:

[0063] The front / rear / left / right contour measuring mechanism is raised from the storage position to the measuring position to perform contour detection on the relevant measuring points on the glass

[0064] 22 After the measurement is completed, the contour measurement mechanism returns to the storage position

[0065] 23 If the glass contour is qualified, skip the following steps until step 2524. If the glass contour is unqualified, the glass is scrapped, jump to step 2525 to cancel the positioning process, and the Z-axis clamping mechanism returns the glass to the storage position.

[0066] 26Y moves back to the storage position toward the center positioning mechanism.

[0067] 27X positioning clamping mechanism returns to the storage position

[0068] 28. Glass removal process:

[0069] The glass lifting suction cup mechanism moves from the storage position to the adsorption position, sucking the glass 29. The glass lifting suction cup mechanism lifts the glass up with the glass

[0070] 30 The suction of the suction cup is released and the worker takes out the glass 31 The qualified ones are retained and the unqualified ones are scrapped.
