Detailed Implementation

[0027] The utility model objective of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation of this utility model is not limited to the following embodiments.

[0028] like Figure 1 and 2As shown, a magnetic levitation conveying device for glass plate coating includes a base 1, a protective shell 2, a roller drive structure 3, a clamping frame 4, a magnetic levitation structure 6, a guide wheel assembly 7, and a controller 102. The controller 102 is installed inside the base 1, and the protective shell 2 is installed on top of the base 1. The magnetic levitation structure 6 is installed on top of the inner cavity of the protective shell 2, and the roller drive structure 3 is installed on top of the base 1. The guide wheel assembly 7 is installed on the inner wall of the protective shell 2. The upper end of the clamping frame 4 is connected to the magnetic levitation structure 6, and the lower end of the clamping frame 4 is connected to the roller drive structure 3. The clamping frame 4 is inclined, and the guide wheel assembly 7 is located on the downwardly inclined side of the clamping frame 4, corresponding to the upper half of the clamping frame 4. The roller drive structure 3 is connected to the controller 102.

[0029] The base 1 is used to mount the roller drive structure 3 and the protective housing 2, facilitating the fixing and movement of the equipment. The protective housing 2 protects the internal equipment and provides support. The roller drive structure 3 drives the clamp fixing frame 4 to move. The clamp fixing frame 4 fixes the glass plate clamp 5, which can be purchased on the market. The magnetic levitation structure 6 levitates the upper part of the clamp fixing frame 4 through magnetic attraction. The guide wheel assembly 7 prevents the clamp fixing frame 4 from tipping over and hitting the protective housing 2 if the magnetic levitation structure 6 fails, thus preventing normal operation. The controller 102 is a microcontroller used to control the drive motor 309 of the roller drive structure 3.

[0030] like Figure 3-7 As shown, the magnetic levitation structure 6 includes a row of first magnetic strips 601, a first magnet mounting bracket 602, three first connectors 603, a suspension plate 604, three second connectors 605, two second magnet mounting brackets 606, and two rows of second magnetic strips 607. The two rows of second magnetic strips 607 are respectively installed within the two second magnet mounting brackets 606, which are arranged in a mirror image. Both second magnet mounting brackets 606 are connected to the lower ends of the three second connectors 605. The three second connectors 605 are evenly distributed on the top of the two second magnet mounting brackets 606, and their upper ends are obliquely mounted on the suspension plate 604. The suspension plate 604 is bolted to the top of the inner cavity of the protective housing 2. The two second magnet mounting brackets 606 form a through slot through which the row of first magnetic strips 601 can pass. The first magnetic strips 601 and the two rows of second magnetic strips 607 are parallel to each other. One row of second magnetic strips 607 magnetically attracts one side of the first magnetic strip 601, and another row of second magnetic strips 607 magnetically attracts the other side of the first magnetic strip 601. The first magnetic strip 601 is installed inside the first magnet mounting bracket 602. The first magnet mounting bracket 602 is connected to the upper end of the clamp mounting plate 401 of the clamp fixing frame 4 via three first connectors 603, which are evenly distributed.

[0031] Both the first magnetic strip 601 and the second magnetic strip 607 are made of neodymium magnets. The first magnetic strip 601 has two sides, one with an S pole and the other with a N pole. The N poles of one row of second magnetic strips 607 attract the S poles of the first magnetic strip 601, and the S poles of another row of second magnetic strips 607 attract the N poles of the first magnetic strip 601, thus allowing the first magnetic strip 601 to levitate between the two second magnetic strips 607. The first magnet mounting bracket 602 is used to fix the first magnetic strip 601. The first connector 603 is used to connect the first magnet mounting bracket 602 to the clamp mounting plate 401. The suspension plate 604 is used to suspend the second magnet mounting bracket 606 on the inner top wall of the protective shell 2. The second connector 605 is used to connect the suspension plate 604 and the second magnet mounting bracket 606, allowing the second magnet mounting bracket 606 to be tilted. The second magnet mounting bracket 606 is used to install and fix the second magnetic strip 607.

[0032] like Figure 6 As shown, the clamp fixing frame 4 includes a clamp mounting plate 401, a first lateral limiting plate 402, a second lateral limiting plate 403, a first longitudinal limiting plate 404, a second longitudinal limiting plate 405, and a guide bar 406. The top of the clamp mounting plate 401 is connected to the three first connectors 603 of the magnetic levitation structure 6. The bottom of the clamp mounting plate 401 is connected to the guide bar 406. The drive wheel 303 of the roller drive structure 3 drives the guide bar 406 to move. The clamp mounting plate 401 has a square through hole, the size of which is the same as that of the glass plate clamp 5, and the glass plate clamp 5 can be inserted into the square through hole for limiting. The first lateral limiting plate 402 is located above the square through hole, the second lateral limiting plate 403 is located below the square through hole, the first longitudinal limiting plate 404 is located to the left of the square through hole, and the second longitudinal limiting plate 405 is located to the right of the square through hole. The first lateral limiting plate 402, the second lateral limiting plate, the first longitudinal limiting plate 404, and the second longitudinal limiting plate 405 are all installed on the downward inclined side of the clamp mounting plate 401. The first lateral limiting plate 402 and the second lateral limiting plate 403 are parallel to each other, and the first longitudinal limiting plate 404 and the second longitudinal limiting plate 405 are parallel to each other.

[0033] The clamp mounting plate 401 restricts the movement of the glass plate clamp 5. A first lateral limiting plate 402 supports the upper end of the glass plate clamp 5. A second lateral limiting plate 403 supports the lower end of the glass plate clamp 5. A first longitudinal limiting plate 404 supports the left end of the glass plate clamp 5. A second longitudinal limiting plate 405 supports the right end of the clamp. A guide bar 406 can be embedded in the drive wheel 303 of the roller drive structure 3, and the drive wheel 303 can drive the guide bar 406 forward.

[0034] like Figure 8 and 9As shown, the roller drive structure 3 includes a support plate 301, a drive base plate 302, five drive synchronous pulleys 304, five drive wheels 303, five drive shafts 305, four tension adjustment components 306, two first guide wheels 307, a synchronous belt 308, and a drive motor 309. The support plate 301 is vertically mounted on top of the drive base plate 302, and the five drive shafts 305 are rotatably mounted on the support plate 301. One end of each of the five drive shafts 305 is connected to one of the five drive synchronous pulleys 304. The other end of each of the five drive shafts 305 is connected to one of the five drive wheels 303. Each tension adjustment component 306 is located between two adjacent drive synchronous pulleys 304, and all four tension adjustment components 306 are mounted on the support plate 301. The two first guide wheels 307 are located below the five drive synchronous pulleys 304, and the drive motor 309 is mounted on the bottom of the drive base plate 302. Five drive synchronous pulleys 304, two first guide pulleys 307, and a drive motor 309 are connected by a synchronous belt 308. The guide bar 406 of the fixture fixing frame 4 can be embedded in the five drive pulleys 303 and moved by the five drive pulleys 303.

[0035] Support plate 301 is used to mount and fix drive shaft 305, tension adjustment component 306, and first guide wheel 307. Drive base plate 302 is used to mount drive motor 309 and support plate 301. Drive synchronous wheel 304 is driven by synchronous belt 308, thereby realizing the rotation of drive synchronous wheel 304. Drive wheel 303 is used to drive guide bar 406 to move. Drive shaft 305 transmits power from drive synchronous wheel 304 to drive wheel 303. Tension adjustment component 306 is used to control the tension of synchronous belt 308. First guide wheel 307 is used to change the transmission direction of synchronous belt 308. Synchronous belt 308 plays a transmission role. Drive motor 309 provides power to drive wheel 303.

[0036] like Figure 10 As shown, each tension adjustment assembly 306 includes two first adjustment screws 306a, two adjustment blocks 306b, an adjustment wheel seat 306c, two second adjustment screws 306d, two fixed shafts 306e, and two tension adjustment wheels 306f. The adjustment wheel seat 306c has two adjustment slots. The second adjustment screws 306d are adjustable up and down and pass through the two adjustment slots, and are mounted on the support plate 301. The adjustment blocks 306b are mounted above the adjustment wheel seat 306c and on the support plate 301. The first adjustment screws 306a are threaded onto the adjustment blocks 306b and pass through them, then abut against the adjustment wheel seat 306c. The two tension adjustment wheels 306f are rotatably mounted on the two fixed shafts 306e. The two fixed shafts 306e are mounted on the adjustment wheel seat 306c, and the tension adjustment wheels 306f press against the timing belt 308.

[0037] The first adjusting screw 306a is used to adjust the longitudinal position of the adjusting wheel adjusting seat 306c. The adjusting block 306b is threadedly connected to the first adjusting screw 306a, and the extension length of the first adjusting screw 306a is adjusted by rotating the first adjusting screw 306a. The adjusting wheel adjusting seat 306c can be longitudinally adjusted on the support plate 301 to realize the longitudinal position of the tension adjusting wheel 306f. The second adjusting screw 306d is used to lock the longitudinal position of the adjusting wheel adjusting seat 306c. The fixed shaft 306e is used to install the tension adjusting wheel 306f. The tension adjusting wheel 306f is used to press the timing belt 308, thereby adjusting the tension of the timing belt 308.

[0038] like Figure 11 As shown, the guide wheel assembly 7 includes a longitudinal beam 701, seven roller mounting plates 702, and seven second guide wheels 703. The longitudinal beam 701 is mounted on the inner wall of the protective housing 2, and one end of each of the seven roller mounting plates 702 is evenly mounted on the longitudinal beam 701. The other ends of the seven roller mounting plates 702 are respectively connected to the seven second guide wheels 703. The seven second guide wheels 703 are located on the downward-sloping side of the clamp mounting plate 401 of the clamp fixing frame 4. There is a certain gap between the seven second guide wheels 703 and the clamp mounting plate 401.

[0039] The longitudinal beam 701 is used to fix the roller mounting plate 702. The roller mounting plate 702 is used to mount the second guide wheel 703, which provides support. The second guide wheel 703 is used to reduce friction.

[0040] like Figure 12 As shown, the base 1 includes a frame 101, two roller base plates 103, four support feet 104, and four casters 105. A protective housing 2 is installed on top of the frame 101, and the roller drive structure 3 is also installed on top of the frame 101 and covered by the protective housing 2. A controller 102 is installed inside the frame 101. The two roller base plates 103 are symmetrically installed at the bottom of the frame 101. The four support feet 104 are respectively installed at both ends of the bottom of the two roller base plates 103. The four casters 105 are also respectively installed at the bottom ends of the two roller base plates 103, located to the sides of the four support feet 104.

[0041] A description of the operation of a magnetic levitation conveying device for glass plate coating: During use, multiple magnetic levitation conveying devices are connected sequentially to form a conveyor line. The lower end of the clamping frame 4 moves within the multiple magnetic levitation conveying devices under the drive of the roller drive structure 3. When the clamping frame 4 is tilted, its own weight is divided into two forces: one force is borne by the roller drive structure 3, and the other force is borne by the magnetic levitation structure 6. The force on the lower end of the clamping frame 4 is much less than its own weight, reducing wear on the lower end of the clamping frame 4 and the roller drive structure 3. The upper end of the clamping frame 4 is connected to the magnetic levitation structure 6 by magnetic force, meaning the upper end of the clamping frame 4 does not directly contact the magnetic levitation structure 6, avoiding wear on both the magnetic levitation structure 6 and the upper end of the clamping frame 4. Furthermore, the magnetic levitation structure 6 provides a certain buffering effect against vibrations during the movement of the clamping frame 4.

[0042] The above-described specific embodiments are preferred embodiments of this utility model and are not intended to limit this utility model. Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
