Detailed Implementation

[0040] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0041] A position adjustment device 3 for optical testing of a windshield 4 includes a support mechanism and a placement mechanism on the support mechanism; the support mechanism is connected to the placement mechanism through an adjustment mechanism; the position adjustment device 3 disclosed in this invention, through the coordinated use of the support mechanism, the placement mechanism and the adjustment mechanism, can adjust the placement angle of the windshield 4 as needed, so as to facilitate the detection of the light transmittance of the windshield 4 at a set angle; and reduce the trouble of manually placing the glass to be tested.

[0042] The position adjustment device 3 disclosed in this invention is mainly used for supporting and placing the windshield 4, which facilitates the support and placement of the windshield 4 during subsequent light transmittance testing; in essence, it provides a basic support function and acts as a support component.

[0043] Specifically, the position adjustment device 3 disclosed in this invention mainly includes a support mechanism, which serves as a basic support and a longitudinal support for raising the windshield. In addition, a placement mechanism is provided on the support mechanism. The placement mechanism facilitates the installation of the windshield 4. Furthermore, the support mechanism is connected to the placement mechanism through an adjustment mechanism. The adjustment mechanism allows for adjustment of the tilt position of the placement mechanism as needed, thereby adjusting the tilt angle and position of the windshield 4 placed on the placement mechanism.

[0044] In addition, the support mechanism described in this invention includes a lifting base 21, on which a lifting bracket 24 is connected. The lifting base 21 serves as a basic support for raising the structure, while the lifting bracket 24 is provided on the lifting base 21. The lifting bracket 24 acts as a placement platform, which facilitates the placement of the mechanism and the subsequent arrangement and placement of the rotating parts on the support mechanism.

[0045] Meanwhile, the placement mechanism described in this invention includes a mounting plate 212, which is a flat plate structure and is mainly used for supporting and placing the windshield 4 to be tested. In addition, the mounting plate 212 is connected to the lifting bracket 24 through an adjustment mechanism. The adjustment mechanism includes a tilt adjustment mechanism for adjusting the tilt angle of the mounting plate 212. The tilt adjustment mechanism of this invention can realize the adjustment of the tilt angle of the mounting plate 212. In actual use, it is mainly used in conjunction with the connecting mechanism.

[0046] In addition, the mounting plate 212 described in this invention is provided with a side blocking mechanism. The side blocking mechanism provides a good end stop, which facilitates the stability of the windshield 4 on the inclined mounting plate 212 when the mounting plate 212 is tilted. At the same time, the side blocking mechanism in this invention includes a stop post 210 provided on the mounting plate 212. The stop post 210 is generally set perpendicular to the mounting plate 212 during normal use, thereby providing a good blocking and limiting effect and ensuring the stable placement of the glass to be inspected on the placement mechanism.

[0047] Furthermore, in this invention, a longitudinal adjustment mechanism is connected between the lifting base 21 and the lifting bracket 24. This longitudinal adjustment mechanism facilitates the adjustment of the position of the lifting bracket 24, thereby adjusting the longitudinal position of the placement mechanism. In actual design, the longitudinal adjustment mechanism is primarily a lifting cylinder 23. The extension and retraction of the lifting cylinder 23 allows the lifting bracket 24 to move longitudinally relative to the lifting base 21. Based on this design, the placement mechanism's position is easily adjusted, thus allowing for adjustment of the position of the glass under test, facilitating control of the subsequent contact between the glass under test and the conveyor line, and enabling the movement of the glass under test's position.

[0048] In actual installation, the lifting cylinder is connected to the lifting support through a bridging frame; the bridging frame plays a good bridging role and facilitates the connection between the lifting cylinder and the lifting support.

[0049] Furthermore, the tilt adjustment mechanism described in this invention includes an adjustment cylinder 29; one end of the adjustment cylinder 29 is hinged to the mounting plate 212, and the other end is connected to the lifting bracket 24; in actual connection, the adjustment lever is mainly connected to the mounting plate on the lifting bracket; the adjustment cylinder 29 is tilted, and the adjustment cylinder can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. The tilt adjustment mechanism of this invention is mainly used to adjust the tilt angle of the mounting plate 212; in actual use, through the extension and retraction of the adjustment cylinder 29, in conjunction with the connecting mechanism described below, the mounting plate 212 rotates, thereby realizing the adjustment of the tilt angle of the mounting plate 212.

[0050] Furthermore, the side guard mechanism in this invention also includes a side guard adjustment mechanism; the side guard adjustment mechanism includes a rotating shaft 215, which is connected to the mounting plate 212 via a bearing mechanism; a stop post 210 is provided at each end of the rotating shaft 215; the side guard adjustment mechanism also includes a stop post control cylinder 211 disposed on the mounting plate 212; the stop post control cylinder 211 is connected to the rotating shaft 215 via a connecting plate 218; the arrangement of the rotating shaft 215 and the bearing mechanism facilitates the rotation of the rotating shaft 215 on the mounting plate 212; the rotating shaft 215 is fixedly connected to the stop post 210, and then... The connecting plate 218 is pulled by the stop control cylinder 211, which drives the rotating shaft 215 to rotate, thereby rotating the stop 210. This allows control over the orientation of the stop 210. When obstruction is required, the stop 210 is arranged perpendicular to the mounting plate 212. When obstruction is required, the stop 210 is parallel to or tilted to avoid obstruction, thus preventing the stop 210 from blocking the windshield 4 and facilitating the subsequent transfer and repositioning of the windshield 4 in conjunction with the conveyor line. In addition, to avoid interference, the piston rod of the stop control cylinder 211 is connected to the connecting plate 218 using a rotating pin.

[0051] In this invention, the stop column control cylinder is connected to the lower end face of the mounting plate via a hinge.

[0052] Furthermore, in this invention, the stop post includes a stop post body 2-1, on which a stop post sleeve 2-2 is provided. The stop post sleeve 2-2 is fitted onto the stop post body 2-1, and the stop post sleeve 2-2 and the stop post body 2-1 are connected by a thread. The stop post sleeve 2-2 is provided with multiple engaging ring grooves 2-3, each engaging ring groove 2-3 including an upper end face 2-31 and a lower end face 2-33. The upper end face 2-31 and the lower end face 2-33 are connected by a longitudinal surface 2-32. The lower end face 2-33 is an arc-shaped surface. The engagement ring grooves 2-3 are provided in this way. This design facilitates the limiting of the end of the glass to be tested, thus giving the glass an upper binding force and better ensuring the stability of the glass on the mounting plate. In addition, the lower end face of the locking ring groove 2-3 is required to be arc-shaped in this invention. This design allows the stop post to disengage properly from the glass to be tested when it is tilted, avoiding interference. Furthermore, in actual design, the stop post sleeve 2-2 is required to be able to move along the axial direction of the stop post body 2-1, so that the height of the corresponding locking ring groove 2-3 can be adjusted according to the thickness of the glass to be tested, increasing the applicability of this invention.

[0053] Furthermore, in this invention, the lifting bracket 24 is connected to the lifting base 21 via a slide rail mechanism; the slide rail mechanism includes a slide rail 221 disposed on the lifting base 21 and a sliding block 22 disposed on the lifting bracket 24, and the lifting bracket 24 is engaged with the slide rail 221 by the sliding block 22; the slide rail mechanism plays a good guiding role, ensuring the linearity of the movement of the lifting bracket 24 on the lifting base 21.

[0054] Furthermore, the mounting plate 212 in this invention is provided with multiple support parts; each support part includes a top column 213 disposed on the mounting plate 212; the multiple top columns 213 are distributed at intervals on the mounting plate 212; the setting of the top columns 213 plays a good supporting and elevating role, making it convenient for the windshield 4 to move away from the mounting plate 212, and facilitating the subsequent detachment of the windshield 4 in conjunction with the conveying mechanism 3. In actual design, at least one support part is set at each of the four corners of the mounting plate 212, and the ends of the support parts are arc-shaped, which plays a good supporting and elevating role and provides protection, ensuring the stability of the windshield 4 placed on the mounting plate 212; at the same time, the support parts set at the four corners of the mounting plate can provide support for the glass to be tested at four positions, ensuring that both ends of the glass to be tested are in a suspended state, facilitating the contact between the conveying mechanism and the glass to be tested; realizing the movement and change of the position of the glass to be tested.

[0055] Furthermore, in this invention, the placement mechanism is connected to the lifting bracket 24 via a rotating part. The rotating part allows for adjustment of the placement mechanism's position on the lifting bracket 24, primarily to change the orientation of the windshield 4, thereby better facilitating the detection of the glass's light transmittance using a transmittance testing instrument. In practical design, the rotating part can be a rotating motor, for example, a rotating motor that drives the mounting plate 214 to rotate, thereby rotating the placement mechanism mounted on the mounting plate 214. In actual arrangement, to ensure convenient and stable placement of the mechanism, this invention requires the rotating part... The device includes a rotary bearing 25 mounted on a lifting bracket 24, with a mounting plate 214 on the rotary bearing 25. The placement mechanism is connected to the rotary bearing 25 via the mounting plate 214. This arrangement not only facilitates the placement of the placement mechanism on the lifting bracket 24 but also allows for rotation of the placement mechanism on the lifting bracket 24. Furthermore, based on the above, it is clear that the mounting plate 214 facilitates the placement of the placement mechanism. In actual arrangement, the adjusting cylinder 29 is also mounted on the mounting plate 214 and hinged to it, as shown in the attached drawings.

[0056] Furthermore, the lifting bracket 24 in this invention is provided with an identification mechanism, which includes a position sensor 26 disposed on the lifting bracket 24 and a position sensing plate 27 disposed on the mounting plate 214; the position sensing plate 27 is used in conjunction with the position sensor 26; through the setting of the identification mechanism, the rotation position of the mounting plate 214 can be monitored.

[0057] In practical design, the position adjustment device 3 disclosed in this invention also includes a control system. The control system includes a detection module, which is connected to the control module, and the control module is connected to the execution module. The identification mechanism disclosed above in this invention is actually equivalent to an identification module. The identification module is mainly used for signal identification. The control module is mainly a controller, which can be a microcontroller or a traditional industrial computer. It is mainly used to receive signals sent by the detection module, identify and judge them, and finally issue instructions. The execution module can be the adjustment cylinder, lifting cylinder, and other adjustment components or mechanisms mentioned above in this invention. After receiving the signal sent by the control module, the execution module performs the corresponding action. Based on the above design, the overall operation of the position adjustment device 3 is made intelligent.

[0058] Furthermore, in this invention, the mounting plate 212 is connected to the mounting plate 214 via a connecting mechanism. The connecting mechanism includes a lower rotating shaft 216 disposed on the mounting plate 212. The lower rotating shaft 216 is connected to the mounting plate 214 via a bearing mechanism, and the lower rotating shaft 216 is connected to the mounting plate 212 via a support frame 217. The connection mechanism facilitates the connection and arrangement of the mounting plate 212 on the mounting plate 214. At the same time, the lower rotating shaft 216 facilitates the rotation of the mounting plate 212. Subsequently, in use, it can be used in conjunction with a tilt adjustment mechanism to adjust the tilt angle of the mounting plate 212, thereby adjusting the detection angle of the windshield 4.

[0059] Furthermore, in this invention, the mounting plate 214 is provided with an marking mechanism 28, which includes a scale plate 219 disposed on the mounting plate 214, and an indicator needle 220 disposed at the end of the lower rotating shaft 216. The indicator needle 220 is connected to the end of the lower rotating shaft 216 and extends to the scale plate 219. The scale plate 219 is provided with angle markings. The tilt angle of the mounting plate 212 can be obtained by the position of the indicator needle 220, thereby more intuitively determining the tilt arrangement of the mounting plate 212 and clarifying whether the tilt angle of the mounting plate 212 meets the detection requirements.

[0060] A windshield 4 inspection conveyor assembly includes a support frame 1, on which two spaced-apart conveying mechanisms 3 are provided. A position adjustment device 3 is arranged between the two conveying mechanisms 3. The conveyor assembly mainly includes the conveying mechanisms 3 and the position adjustment device 3. Each conveying mechanism 3 primarily consists of a conveyor belt connected to a drive motor. The drive motor is connected to the conveyor belt via pulleys. In specific implementation, one drive motor drives the pulleys on both conveyor belts through a transmission shaft, thereby ensuring the consistency of movement between the two conveying mechanisms. Specifically, as shown in the attached drawings, the two conveying mechanisms 3 share a single drive motor, ensuring consistent movement between them. Based on this design, the windshield 4 can operate autonomously on the production line. The conveying mechanisms 3 enable loading and unloading operations onto the position adjustment device 3, facilitating practical operation.

[0061] Furthermore, in this invention, the lifting base is connected to the mounting base; the mounting base is provided with adjustment support parts at the four corners; the adjustment support parts include threaded rods, and support pads are provided under the threaded rods. In addition, in this invention, the threaded rods are provided with upper nuts and lower nuts, which are distributed on the upper and lower sides of the mounting base. This arrangement facilitates the adjustment of the horizontality of the position adjustment device as needed.

[0062] specific:

[0063] This invention discloses a position adjustment device 3 for optical inspection of windshield 4; this invention can realize the automatic tilting angle of windshield 4, and the angle is set according to the product without manual adjustment.

[0064] When the windshield 4 rotates, the position sensor 26 is interlocked with the cylinder control signal to ensure operational safety; the size of the mounting plate 212 can be adjusted to accommodate different models of windshields 4; that is, a locking cylinder can be set between the mounting plate and the lifting bracket of this invention, specifically the locking cylinder is set on the lifting bracket; a pressing plate is provided at the end of the locking cylinder, and the pressing plate can be easily changed as needed to whether the pressing plate and the mounting plate are interfacing, thereby realizing the position locking of the mounting plate; in actual arrangement, the locking cylinder is arranged longitudinally; the pressing plate is arranged transversely.

[0065] Conventional automotive windshields are typically laminated glass, and their light transmittance has standard requirements. Since the light transmittance test light source is usually fixed, the windshield needs to be able to swing up and down and rotate in plane relative to the light source to achieve optimal light transmittance test data.

[0066] Therefore, this invention discloses a windshield 4 detection conveyor assembly. The conveyor assembly mainly includes a conveyor line, which includes two oppositely arranged conveyor mechanisms 3. In actual use, the windshield 4 is stopped by the stop column 210 while running on the conveyor line. The detection switch detects the glass, the conveyor line stops running, the position adjustment device 3 of this invention is activated, the lifting cylinder 23 lifts upward, and the arc surface of the top column 213 drags the windshield 4 upward, causing the glass to detach from the conveyor line body. The adjustment cylinder operates, so that the mounting plate 212 is at a certain angle to the horizontal plane, and the marking mechanism 28 facilitates manual verification of the angle. In addition, in this invention, the rotary bearing 25 allows the entire glass to rotate 360°. The position sensor 26 and the position sensing plate 27 lock the action sequence of the lifting cylinder 23 in the program. The lifting cylinder 23 can only retract downward when the mounting plate 212 is in the specified position, preventing malfunction and avoiding the windshield 4 or the position adjustment device 3 from hitting the conveyor line.

[0067] After the windshield 4 is inspected, the adjusting cylinder 29 retracts and the lifting cylinder 23 retracts, the glass falls onto the conveyor line, the baffle control cylinder 211 is activated, the baffle 210 retracts, and the windshield 4 moves to the next station.

[0068] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
