[0037] Refer to the following Figure 1 to Figure 2 The substrate height adjustment mechanism and the conveying and coating equipment provided by the utility model are described.
[0038] The transport coating equipment includes a transport platform 3 , a transport carrier 4 , a spraying mechanism 5 and a substrate height adjustment mechanism. The transport carrier 4 and the spraying mechanism 5 are both arranged above the transport platform 3 , and the substrate height adjustment mechanism is arranged above the transport carrier 4 .
[0039] Furthermore, the transport platform 3 includes a first base 31 , a first sliding platform 32 , a second base 33 and a second sliding platform 34 . The first sliding platform 32 is connected to the first sliding platform 32 , and the second sliding platform 34 is connected to the second base 33 .
[0040] Specifically, the first base 31 is placed on the floor of the factory building, and a plurality of first sliding platforms 32 are arranged at intervals on the first base 31. The plurality of first sliding platforms 32 are arranged in parallel. In this embodiment, two are taken as an example, and the first sliding platforms 32 are arranged horizontally. The first sliding platform 32 is made of marble, granite, vacuum stone or stainless steel. In this embodiment, it is made of marble. Marble has the advantages of fine and hard texture, high compressive strength, low water absorption, easy processing, good opening, etc. It can ensure the flatness of the first sliding platform 2, and it is stable in operation and not easy to deform, so as to ensure stable support for the object.
[0041] Further, each first slide table 32 is connected to a first guide rail 321, the first guide rail 321 is arranged parallel to the first slide table 32, the transport carrier 4 is connected to the first guide rail 321, the transport carrier 4 slides in the horizontal direction, and the transport carrier 4 is any carrier in the prior art that can carry the substrate 100. Its specific structure is the prior art and is not repeated here. Optionally, the first guide rail 321 is an air-floating guide rail or a magnetic suspension guide rail. This embodiment takes the air-floating guide rail as an example, and uses the air-floating guide rail to reduce the vibration of the substrate 100 during transportation and reduce the wear on the substrate 100.
[0042] Furthermore, the second base 33 is placed on the floor of the factory, and multiple second bases 33 are arranged at intervals, and the first base 31 is located between two adjacent second bases 33 . This embodiment takes two second bases 33 as an example, that is, the first base 31 is located between two second bases 33 .
[0043] The second sliding platform 34 is connected to the top of the second base 33. One second sliding platform 34 is provided for each second base 33. The second sliding platform 34 is provided parallel to the first sliding platform 32. The second sliding platform 34 is made of marble, granite and vacuum stone with high hardness and wear resistance. In this embodiment, it is made of marble. The spraying mechanism 5 is connected to the second base 33. The spraying mechanism 5 is any mechanism in the prior art that can perform fixed-point spraying on the substrate 100. The spraying mechanism 5 sprays the slurry through a nozzle. The nozzle of the spraying mechanism 5 can slide in the vertical direction. Its specific structure is the prior art and will not be repeated here.
[0044] Based on the above, using four marble strips to replace the existing whole marble not only saves materials, but also makes transportation and installation more convenient, greatly saving production costs. Connecting the spraying mechanism 5 to the second sliding table 34 can prevent the vibration generated by the spraying mechanism 5 when working from being transmitted to the first sliding table 32, thereby reducing the vibration transmitted to the substrate 100, preventing the generation of vibration superposition effect, and ensuring the accuracy of the substrate 100 transportation.
[0045] The substrate height adjustment mechanism is intended to obtain the height data of the substrate 100 during the process of the substrate 100 being transported by the carrier 4, and to adjust the local height of the substrate 100 to correct the posture of the substrate 100, so that the substrate 100 is in a horizontal state, and a preset coating gap is maintained between the substrate 100 and the spraying mechanism 5, which not only adjusts the coating thickness, but also makes the coated slurry evenly distributed, thereby improving the coating uniformity. Please refer to the following for an exemplary structure of the substrate height adjustment mechanism.
[0046] The substrate height adjustment mechanism includes a positioning adjustment component 1, a detection unit 2 and a control unit. The positioning adjustment component 1 is connected to the top of the transport carrier 4. The positioning adjustment component 1 can support and position the substrate 100 and adjust the local height of the substrate 100, correct the substrate 100 to a horizontal state, and maintain a preset coating gap between the substrate 100 and the nozzle. The detection unit 2 is connected to the top of the conveying platform or the spraying mechanism 5. The detection unit 2 is provided with multiple detection units along the conveying direction perpendicular to the substrate 100. The detection unit 2 can detect the height of the substrate 100 below itself. The control unit is a controller (not shown in the figure), and the controller is electrically connected to the positioning member and the detection unit 2.
[0047] Specifically, the positioning and adjustment assembly 1 includes a positioning member (not shown in the figure) and a driving member (not shown in the figure), the positioning member is connected to the transport carrier 4, the positioning member can support and position the substrate 100, the positioning member is a suction cup or a glass clamp, and the present embodiment is preferably a suction cup. At least two groups of positioning members are arranged along the conveying direction perpendicular to the substrate 100, and the present embodiment takes two groups as an example, and each group of positioning members is arranged along the conveying direction parallel to the substrate 100, and the present embodiment takes two as an example.
[0048] It should be noted that the substrate 100 in this embodiment is arranged in a square shape, and two opposite sides thereof are parallel to the conveying direction of the substrate 100, and four suction cups are arranged in this embodiment, and the four suction cups are distributed under the four corners of the substrate 100, and the substrate 100 is adsorbed by an external vacuum air source through the suction cups.
[0049] The height of each positioning member can be adjusted. Specifically, a driving member is connected to the transport carrier 4. A driving member is provided for each positioning member. A single positioning member is connected to a single driving member. The driving member can drive the positioning member to move in a vertical direction. The driving member is any component in the prior art such as a cylinder, an oil cylinder, an electric cylinder or a motor that can drive the positioning member to move in a straight line. This embodiment is explained by taking a servo motor as an example. A single suction cup is driven to rise and fall by a single cylinder, so that the local height of the substrate 100 can be adjusted until the substrate 100 is corrected to a horizontal state.
[0050] Furthermore, a guide rail (not shown) is connected to the transport carrier 4, the guide rail is arranged in the vertical direction, and the positioning member is slidably connected to the guide rail. The guide rail guides and limits the sliding of the positioning member.
[0051] Exemplarily, the detection unit 2 in this embodiment is connected to the spraying mechanism 5 and is located on one side of the spraying mechanism 5 close to the feeding end of the conveying platform 3, so as to detect the height of the substrate 100 before the substrate 100 reaches below the nozzle of the spraying mechanism 5. Optionally, the detection unit 2 is a visual sensor, a height sensor or a distance sensor. In this embodiment, the distance is described using a distance sensor. Two distance sensors are arranged along a direction perpendicular to the vertical direction of the substrate 100, and the distance sensors are close to the side position of the substrate 100 perpendicular to its own conveying direction.
[0052] Based on the above, when the substrate 100 is conveyed to the spraying mechanism 5, when the substrate 100 just reaches the bottom of the distance measuring sensor, the distance measuring sensor is used to measure the distance of the two corners of the substrate 100 close to the spraying mechanism 5. If the measured data deviates from the preset value, the height of the two positioning members close to the forward direction of the substrate 100 is adjusted in time, and then the substrate 100 continues to be conveyed forward. If the measured data deviates from the preset value, the height of the remaining two positioning members is adjusted until the measured data reaches the preset value, so that the substrate 100 is in a horizontal state and maintains a preset coating gap with the nozzle.
[0053] It should be noted that the controller is electrically connected to the control system of the conveying and coating equipment, and a program can be input into the controller in advance to set the alarm threshold and the adjustment threshold, and the alarm threshold is greater than the adjustment threshold. When the deviation between the measured data and the preset value is greater than the alarm threshold, the alarm is immediately controlled to sound an alarm and the conveyance of the substrate 100 is stopped at the same time. When the deviation between the measured data and the preset value is between the alarm threshold and the adjustment threshold, the height of the substrate 100 is adjusted.
[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
