Description

Technical Field

[0001] The utility model relates to the technical field of a glass coating rapid plate changing mechanism, in particular to a glass coating rapid plate changing mechanism. Background Art

[0002] Glass coating generally involves applying a thin film of a specific material to the glass surface to reduce light reflection and thus improve the glass's light transmittance. However, if the glass surface has severe scratches, dirt, or other damage that could affect the coating's effectiveness and durability, this can affect the coating's effectiveness. Therefore, when coating glass, a detection device is first used to inspect the glass surface. Based on the test results, the glass is then replaced. This prevents the coating device's internal sensors from detecting the glass, halting the coating process and avoiding the production of defective products and wasting coating material.

[0003] At present, glass coating production generally adopts an assembly line production method, and glass coating usually uses consistent coating or spraying technology, resulting in the glass plates not being strictly positioned on transportation mechanisms such as roller conveyors. As a result, conventional unloading devices such as robotic arms are unable to directly and accurately grasp the glass plates. Manual control of the robotic arms or manual replacement of the glass plates are required, resulting in a slow replacement speed of the glass plates, affecting production efficiency. Utility Model Content

[0004] The utility model provides a glass coating fast plate changing mechanism, which solves the problem of slow glass plate changing speed in the related art.

[0005] The technical solution of the utility model is as follows:

[0006] A glass coating rapid plate changing mechanism comprises a first conveying structure and a second conveying structure, wherein the first conveying structure comprises a conveying bracket and a plurality of conveying shafts, and the first conveying structure is provided with a plate unloading assembly for conveying the glass plate to the second conveying structure, and a lifting assembly for controlling the lifting of the plate unloading assembly;

[0007] The plate unloading assembly includes a plate unloading frame, a conveying unit for conveying the glass plate, and a driving unit for driving the conveying unit.

[0008] Furthermore, the plate unloading rack includes a first lifting rod and a second lifting rod, and the first lifting rod and the second lifting rod are symmetrically distributed with the second conveying structure as the center.

[0009] Furthermore, each of the conveying units includes a plurality of conveying wheels, the first lifting rod and the second lifting rod are rotatably connected to the plurality of conveying wheels, and the first lifting rod and the second lifting rod are each provided with a driving unit.

[0010] Furthermore, each of the driving units includes a linkage belt, a driving wheel, a driving motor, and several driven wheels. The driving wheel is linked to the output shaft of the driving motor. The linkage belt links the driving wheel and each driven wheel. Each driven wheel is fixedly connected to each conveying wheel in a one-to-one correspondence.

[0011] Furthermore, the lifting assembly includes a first lifting unit for controlling the first lifting rod to be lifted and lowered, and a second lifting unit for controlling the second lifting rod to be lifted and lowered. The first lifting unit and the second lifting unit are both scissor-type telescopic frames.

[0012] Furthermore, the first lifting rod and the second lifting rod are both in an L-shaped structure in the axial projection plane of the conveying shaft, and each of the conveying wheels is located between the first lifting rod and the second lifting rod.

[0013] Furthermore, the highest point of the second lifting rod has a higher level than the highest point of the conveying shaft.

[0014] Furthermore, a buffer strip is provided at one end of the second lifting rod close to the conveying wheel, and a buffer layer is provided on each of the conveying wheels.

[0015] Furthermore, a balance plate is provided on one end of the first lifting rod close to the second lifting rod and on one end of the second lifting rod close to the first lifting rod.

[0016] The working principle and beneficial effects of the utility model are as follows:

[0017] The utility model comprises a first conveying structure and a second conveying structure, wherein: the first conveying structure is used for normal conveying of glass plates, and the second conveying structure is used for conveying replaced glass plates. The first conveying structure is provided with a plate unloading assembly for conveying the glass plates to the second conveying structure, and a lifting assembly for controlling the lifting of the plate unloading assembly.

[0018] When the detection device detects damage on the surface of the glass sheet, the lifting assembly is used to lift the unloading assembly, so that the conveying function of the first conveying structure can no longer act on the glass sheet. The unloading assembly includes a conveying unit and a driving unit for driving the conveying unit. By activating the driving unit, the conveying unit in the unloading assembly starts to convey the glass sheet, thereby sending the glass sheet to the second conveying structure, completing the glass sheet replacement work.

[0019] When the glass plate is replaced by the above structure, the overall movement direction of the glass plate is linear. Compared with unloading structures such as robotic arms, the utility model does not perform work such as grabbing the glass plate or displacement of the structure itself, making the glass plate replacement work more intuitive and concise, and the process clear and easy to understand, so that the staff can understand and execute the steps of replacing the glass plate faster and better, thereby improving the speed of glass plate replacement.

[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1 、 Figure 3As shown, this embodiment proposes a glass coating rapid plate changing mechanism, which mainly includes a first conveying structure 1 and a second conveying structure 2. The conveying directions of the first conveying structure 1 and the second conveying structure 2 are perpendicular to each other, which facilitates changing the conveying direction of the damaged glass plate and realizes the replacement of the glass plate;

[0032] The first conveying structure 1 is provided with a plate unloading assembly 3 for conveying the glass sheet to the second conveying structure 2, and a lifting assembly 4 for controlling the lifting and lowering of the plate unloading assembly 3. The first conveying structure 1 also includes a conveying support 11 and a plurality of conveying shafts 12. That is, the first conveying structure 1 adopts a roller conveyor structure to convey the glass sheet. By taking advantage of the gaps between the conveying shafts 12 in the roller conveyor structure, the plate unloading assembly 3 can be inserted into the gaps between adjacent conveying shafts 12, thereby preventing interference between the plate unloading assembly 3 and the first conveying structure 1 when the lifting assembly 4 lifts the plate unloading assembly 3, which would make this embodiment unworkable.

[0033] The unloading assembly 3 includes an unloading frame 31, a conveying unit 32 for conveying the glass plate, and a driving unit 33 for driving the conveying unit 32. The unloading frame 31 is linked to the lifting assembly 4, and the conveying unit 32 and the driving unit 33 are both installed on the unloading frame 31, so that the lifting assembly 4 can control the unloading assembly 3 to lift and lower. When the detection device detects that the glass plate is damaged and when the damaged glass plate reaches the corresponding position of the unloading assembly 3, the lifting assembly 4 is started to control the unloading assembly 3 to lift, so that the glass plate is separated from the first conveying structure 1, thereby canceling the conveying force of the first conveying structure 1 on the glass plate and stopping the movement of the glass plate along the conveying direction of the first conveying structure 1. When the unloading assembly 3 reaches the specified position (completing the connection with the second conveying structure 2), the conveying unit in the unloading assembly 3 is acted upon by the driving unit 33 to convey the glass plate on the unloading assembly 3, so that the glass plate enters the second conveying structure 2, completing the replacement of the glass plate.

[0034] To sum up, compared with the traditional robotic arm, which needs to complete the grabbing of the glass plate and the movement, rotation or flipping of the robotic arm itself after grabbing to complete the replacement of the glass plate; this embodiment uses the mutual cooperation between various components to make the glass plate itself perform multiple segments of linear movement to complete the replacement of the glass plate, making the replacement of the glass plate more intuitive and concise, and the replacement process of the glass plate clearer and easier to understand, so that the staff can understand and execute the steps of replacing the glass plate faster and better, thereby improving the replacement speed of the glass plate.

[0035] like Figures 1 to 3As shown, the plate unloading frame 31 in this embodiment includes a first lifting rod 311 and a second lifting rod 312. The first lifting rod 311 and the second lifting rod 312 are symmetrically distributed with the second conveying structure 2 as the center, and the distance between the first lifting rod 311 and the second lifting rod 312 should be smaller than the width of the glass plate actually produced on the horizontal projection plane, that is, there should be at least one conveying shaft 12 between the first lifting rod 311 and the second lifting rod 312 to ensure that the glass plate can be lifted by the mutual cooperation of the first lifting rod 311 and the second lifting rod 312. During the lifting process of the glass plate, the plate unloading frame 31 can evenly withstand the pressure caused by lifting the glass plate, thereby ensuring the smooth lifting of the glass plate.

[0036] Moreover, the width dimensions of the first lifting rod 311 and the second lifting rod 312 on the horizontal projection plane should be equal to the width dimension of the conveying surface of the first conveying structure 1, so that even if the glass plate is not strictly positioned on the first conveying structure 1, it can smoothly enter the working range of the unloading assembly 3 when the glass plate reaches the designated position (the position where the unloading assembly 3 is located).

[0037] like Figures 3 and 4 As shown, each conveying unit 32 in this embodiment includes a plurality of conveying wheels 321, and the first lifting rod 311 and the second lifting rod 312 are rotatably connected to the plurality of conveying wheels 321, that is, the rotation of each conveying wheel 321 completes the conveying work of conveying the glass plate to the second conveying structure 2, and conveying the glass plate in the form of rollers can effectively reduce the contact area with the glass plate, prevent secondary damage to the glass plate when the conveying unit 32 conveys the glass plate, and ensure the recycling value of the glass plate; the spacing between the conveying wheels 321 on the first lifting rod 311 and the spacing between the conveying wheels 321 on the second lifting rod 312 should be less than or equal to the spacing between adjacent conveying shafts 12, to ensure the stability of the unloading assembly 3 when conveying the glass plate.

[0038] Both the first lifting rod 311 and the second lifting rod 312 have a driving unit 33, so that the conveying wheels 321 on the first lifting rod 311 and the second lifting rod 312 are driven by two independently designed driving units 33, and the two do not interfere with each other, which facilitates later maintenance work; and when one of the driving units 33 is damaged, the conveying wheels 321 on the first lifting rod 311 or the second lifting rod 312 (the side driven by the undamaged driving unit 33) can still maintain the conveying function of the glass plate, thereby ensuring the reliability and stability of the operation of the plate unloading assembly 3.

[0039] like Figures 5 and 6As shown, each driving unit 33 in this embodiment includes a linkage belt 331, a driving wheel 332, a driving motor 333, and a plurality of driven wheels 334. The driving wheel 332 is linked to the output shaft of the driving motor 333, and the linkage belt 331 links the driving wheel 332 and each driven wheel 334. The linkage belt 331 in this embodiment is preferably a synchronous belt, which uses the tooth structure on the synchronous belt to ensure the accuracy of the linkage when each driven wheel 334 is linked to the driving wheel 332; and there should be at least two linkage belts 331, and the linkage between the driving wheel 332 and the driven wheel 334 and the linkage between each driven wheel 334 are independently designed. Therefore, when the linkage between the driving wheel 332 and the driven wheel 334 or the linkage between each driven wheel 334 fails in the later stage, only part of the linkage belt 331 needs to be replaced, which reduces the later maintenance cost of the drive unit 33.

[0040] Each driven wheel 334 is fixedly connected to each conveying wheel 321 in a one-to-one correspondence, ensuring the linkage relationship between each conveying wheel 321 and each driven wheel 334, so that each conveying wheel 321 can rotate under the drive of the driving unit 33; at the same time, the driving motor 333 in this embodiment is preferably an AC motor or other motor that can provide efficient power output, thereby ensuring that the driving motor 333 can drive each conveying wheel 321 to rotate, thereby ensuring the stability of the unloading operation of the unloading assembly 3.

[0041] like Figures 1 and 2 、 Figures 4 to 7 As shown, the lifting assembly 4 in this embodiment includes a first lifting unit 41 for controlling the lifting of the first lifting rod 311, and a second lifting unit 42 for controlling the lifting of the second lifting rod 312, so that the lifting operations of the first lifting rod 311 and the second lifting rod 312 do not interfere with each other, so as to adjust the first lifting rod 311 or the second lifting rod 312 to different height positions.

[0042] The first lifting unit 41 and the second lifting unit 42 are both scissor-type telescopic frames, because the scissor-type telescopic frames are usually composed of multiple crossed support rods, which are locked with each other to form a stable frame, which can effectively support and stabilize the objects supported by them, and are not prone to tilting and shaking, thereby ensuring the supporting strength and support stability of the lifting assembly 4 in this embodiment.

[0043] Moreover, the first lifting unit 41 and the second lifting unit 42 should be equipped with a servo motor and a screw for driving themselves to lift and lower. Through the mutual cooperation of the screw, the servo motor, the first lifting unit 41 or the second lifting unit 42, the driving force of the servo motor is used to ensure that the lifting work of the first lifting rod 311 and the second lifting rod 312 can be completed quickly, thereby ensuring the replacement speed of the glass plate in this embodiment, and can realize the precise lifting of the first lifting unit 41 and the second lifting unit 42 with the help of the high-precision control characteristics of the servo motor.

[0044] If necessary, a limiting component such as a limiting rod can be added to the second conveying structure 2 to constrain the movement range of the first lifting rod 311 and the second lifting rod 312 to further ensure the precise lifting of the first lifting unit 41 and the second lifting unit 42.

[0045] The first lifting rod 311 and the second lifting rod 312 both have an "L"-shaped structure on the axial projection surface of the conveying shaft 12. The highest point of the first lifting rod 311 is higher than the highest point of each conveying wheel 321 on the first lifting rod 311, and the highest point of the second lifting rod 312 is higher than the highest point of each conveying wheel 321 on the second lifting rod 312. Through the mutual cooperation between the first lifting rod 311 and the second lifting rod 312, the glass plate is constrained and limited during the lifting process of the unloading plate assembly 3, preventing the glass plate from sliding back from the unloading plate frame 31 to the first conveying structure 1 during the lifting process, thereby ensuring the stability and practicality of the unloading work; each conveying wheel 321 is located between the first lifting rod 311 and the second lifting rod 312, ensuring that the glass plate lifted by the unloading plate frame 31 is within the conveying range of the conveying unit 32, and ensuring the stability of the conveying force of the conveying unit 32.

[0046] In this embodiment, the lifting rod close to the coating device is used as the second lifting rod 312. Figures 1 and 2 As shown, the highest point of the second lifting rod 312 has a higher horizontal height than the highest point of the conveying shaft 12, so that the second lifting rod 312 can constrain and limit the glass plate on the first conveying structure 1, preventing the glass plate from crossing the working range of the unloading assembly 3 under the conveying action of the first conveying structure 1, realizing the positioning of the glass plate on the first conveying structure 1, and ensuring the accuracy of the unloading work of the unloading assembly 3 in this embodiment.

[0047] A buffer strip 51 is provided on one end of the second lifting rod 312 close to the conveying wheel 321, and a buffer layer 52 is provided on each conveying wheel 321. In this embodiment, the buffer strip 51 and each buffer layer 52 are preferably made of an elastic material with a long service life, such as rubber;

[0048] The buffer strip 51 buffers the impact force when the glass plate contacts the second lifting rod 312 under the action of the conveying force of the first conveying structure 1, thereby avoiding secondary damage to the glass plate and reducing the recycling value of the glass plate; at the same time, each conveying wheel 321 is provided with a buffer layer 52, which not only buffers the impact force generated when each conveying wheel 321 contacts the glass plate under the action of the lifting component 4, but also because the buffer layer 52 will undergo a certain deformation under the pressure of the glass plate, the deformation increases the contact area between the conveying wheel 321 and the glass plate, thereby increasing the friction between the conveying wheel 321 and the glass plate, which helps to better convey the glass plate to the second conveying structure 2 and ensure the conveying effect.

[0049] The first lifting rod 311 has one end close to the second lifting rod 312, and the second lifting rod 312 has one end close to the first lifting rod 311. Both ends of the conveying wheels 321 on the first lifting rod 311 are rotated to connect the first lifting rod 311 and the balance plate 313 on the first lifting rod 311, and the two ends of the conveying wheels 321 on the second lifting rod 312 are rotated to connect the second lifting rod 312 and the balance plate 313 on the second lifting rod 312, so that each conveying wheel 321 has a force point at both ends, whether it is on the first lifting rod 311 or the second lifting rod 312, to ensure the balance of the conveying wheel 321 itself, avoid the conveying wheel 321 from tilting when subjected to force, and ensure the stability and integrity of the structure of the unloading assembly 3 itself.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
