Description

Technical Field

[0001] The utility model relates to the field of liquid crystal panel transmission equipment, in particular to a liquid crystal panel flexible transmission system. Background Art

[0002] With the continuous development of the new display industry, cleanliness requirements are becoming increasingly higher. Conventional roller transmission has the disadvantage that the roller and the glass transport device are in contact and friction with each other, which easily generates dust particles. Linear motor drive also has the disadvantage that the linear motor moving end has a moving cable, which limits the transmission route.

[0003] The patent disclosed in the existing announcement number CN211768409U discloses an FTS transport platform for automatic assembly of LED downlights. This patent applies electromagnetic guide rails to the transport platform, achieving high-precision and high-speed horizontal displacement of the transport platform with large loads. However, all loads during transportation are carried by the FTS drive coil, resulting in a large FTS load, high cost, and high energy consumption. In addition, the platform's fixed clamping positioning requires physical contact at each workstation and each contact to achieve positioning. Frequent contact easily generates debris, making it unsuitable for transporting liquid crystal panels on display production lines with high cleanliness requirements. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technical problems, the purpose of the utility model is to provide a flexible transmission system for liquid crystal panels that uses magnetic levitation to offset the gravity of the glass carrier and reduce the load, and uses electromagnetic adsorption to replace the original mechanical clamping method to reduce the impact of vibration and debris caused by positioning on product quality.

[0005] In order to solve the problems of the prior art, the technical solutions of the present utility model are as follows:

[0006] A flexible transmission system for a liquid crystal panel includes a body, a glass carrier body magnetically mounted on one side of the body, and the glass carrier body can only move laterally along the length direction of the body body in close contact with the body body;

[0007] A magnet connection plate is fixed to the bottom of the glass carrier body, and an FTS magnetic plate is fixed to the bottom of the magnet connection plate. A plurality of FTS coils are fixed to the lower end of the fuselage body at equal intervals along the length direction of the fuselage body. The FTS coils are located below and directly opposite the FTS magnetic plate. A Hall sensor is fixed to the lower end of the fuselage body on the side of the FTS coil at both ends of each FTS coil. The Hall sensor is electrically connected to the FTS magnetic plate and the FTS coil.

[0008] Positioning components for positioning the glass carrier body are fixed to the upper and lower ends of the body.

[0009] Preferably, a lower magnet is fixed to the lower end of the magnet connecting plate on the side close to the fuselage body, and a lower magnet is fixed to the side close to the magnet at the lower end of the fuselage body, and the lower magnet is located directly above the lower magnet;

[0010] An upper magnet is fixed on the top of the glass carrier body, and a top magnet is fixed on a side of the upper end of the fuselage body close to the glass carrier body, and the top magnet is directly opposite to the upper magnet.

[0011] Preferably, a plurality of auxiliary rollers are sequentially installed side by side along the length direction of the fuselage body at the lower end of the side of the fuselage body close to the glass carrier body;

[0012] Two auxiliary wheel limiting plates arranged vertically and facing each other are fixed on the side of the magnet connecting plate close to the auxiliary roller, and the two auxiliary wheel limiting plates are respectively attached to the outer wall of the auxiliary roller at the upper end and the lower end of the auxiliary roller;

[0013] A plurality of auxiliary guide wheels are fixed in sequence along the length direction of the fuselage body on one side of the lower end of the fuselage body close to the magnet connecting plate, and the auxiliary guide wheels cooperate with the outer wall of the side of the magnet connecting plate away from the fuselage body.

[0014] Preferably, the positioning assembly includes a cylinder and an electromagnet, and a group of cylinders are fixed to the upper and lower ends of the fuselage body, and each group of cylinders is arranged side by side on the fuselage body along the length direction of the fuselage body, and the upper and lower groups of cylinders are positioned opposite each other. An electromagnet is fixed on the side of the cylinder close to the glass carrier body, and the electromagnet cooperates with the glass carrier body;

[0016] Preferably, chip removal magnets are fixed on the outer wall of the main body on both the left and right sides of the auxiliary roller.

[0017] Preferably, a coil shield covering the outside of the FTS coil is fixed to the lower end of the fuselage body, and a magnet shield covering the outside of the top magnet is fixed to the upper end of the fuselage body.

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] 1. Compared with traditional technologies, the present invention utilizes magnetic levitation technology to achieve the connection between the glass carrier body and the fuselage body. The attraction of opposite magnetic poles in the magnetic levitation offsets the carrier's gravity, reducing the load.

During positioning, the glass carrier body will not come into contact with the outer wall of the glass carrier body to generate debris, thereby further improving the cleanliness during transportation.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] See also Figures 1 to 5, this embodiment provides a liquid crystal panel flexible transmission system, including a body body 201, a glass carrier body 102 is installed on one side of the body body 201;

[0029] A lower magnet 105 is fixed to the lower end of the magnet connecting plate 104 on the side close to the fuselage body 201, and a lower magnet 204 is fixed to the side close to the magnet at the lower end of the fuselage body 201, and the lower magnet 204 is located directly above the lower magnet 105;

[0030] The upper magnet 101 is fixed to the top of the glass carrier body 102. A top magnet 202 is fixed to the upper end of the body 201 near the glass carrier body 102. The top magnet 202 faces the upper magnet 101. A magnet protection cover 210 is fixed to the upper end of the body 201 and covers the outer side of the top magnet 202.

[0031] The upper magnet 101 and the lower magnet 105 cooperate with the top magnet 202 and the lower magnet 204 to achieve a magnetic connection between the glass carrier body 102 and the body 201;

[0032] A plurality of auxiliary rollers 203 are mounted in parallel along the length of the main body 201 at the lower end of the side of the main body 201 close to the glass carrier body 102. Debris removal magnets 401 are fixed to the outer wall of the main body 201 on both sides of the auxiliary rollers 203.

[0033] Two auxiliary wheel limiting plates 106 arranged vertically and facing each other are fixed to the side of the magnet connecting plate 104 close to the auxiliary roller 203. The two auxiliary wheel limiting plates 106 are respectively attached to the outer wall of the auxiliary roller 203 at the upper and lower ends of the auxiliary roller 203.

[0034] A plurality of auxiliary guide wheels 206 are fixed in sequence along the length of the body 201 on the side of the lower end of the body 201 close to the magnet connecting plate 104. The auxiliary guide wheels 206 cooperate with the outer wall of the magnet connecting plate 104 on the side away from the body 201.

[0035] The glass carrier body 102 is magnetically attracted to one side of the main body 201. The upward and downward movement of the glass carrier body 102 is limited by the auxiliary wheel limit plate 106, the auxiliary roller 203, and the auxiliary guide wheel 206. The auxiliary wheel limit plate 106 is rotatably connected to the auxiliary roller 203, and the auxiliary guide wheel 206 confines the glass carrier body 102 to a position close to the main body 201, so that the glass carrier body 102 can only move along the side of the main body 201 and the length of the main body 201.

[0036] The glass carrier body 102 and the fuselage body 201 are attracted by magnetism to offset the carrier's own weight, thereby reducing the load.

[0037] A magnet connecting plate 104 is fixed to the bottom of the glass carrier body 102, and an FTS magnetic plate 103 is fixed to the bottom of the magnet connecting plate 104. A plurality of FTS coils 207 are fixed to the lower end of the body 201 at equal intervals along the length of the body 201. A coil shield 208 is fixed to the lower end of the body 201, covering the outer sides of the FTS coils 207. The FTS coils 207 are located below and directly opposite the FTS magnetic plate 103. A Hall sensor 205 is fixed to the lower end of the body 201, adjacent to the FTS coils 207, and at both ends of each FTS coil 207. The Hall sensor 205 is electrically connected to the FTS magnetic plate 103 and the FTS coils 207.

[0038] The controller controls the power supply of the FTS coils 207. When the FTS coils 207 are activated, they generate a changing magnetic field. This magnetic field interacts with the FTS magnetic plate 103, thereby generating a driving force on the magnet connecting plate 104 (and the glass carrier body 102 connected thereto). This driving force causes the glass carrier body 102 to move along the length direction of the fuselage body 201.

[0039] The Hall sensor 205 is responsible for monitoring this movement process. Since the Hall sensor 205 is sensitive to magnetic fields, when the FTS magnetic plate 103 passes by the Hall sensor 205 as the glass carrier body 102 moves, the Hall sensor 205 detects changes in the magnetic field. This information can be converted into an electrical signal and transmitted to the controller.

[0040] The controller can calculate the current position, moving speed, and moving direction of the glass carrier body 102 based on the magnetic field change information provided by the Hall sensor 205. The controller can then adjust the current and magnetic field strength of the FTS coil 207 according to a preset trajectory or instruction, thereby controlling the moving direction and speed of the glass carrier body 102.

[0041] In this way, the Hall sensor 205 works in conjunction with the FTS coil 207 and the FTS magnetic plate 103 to achieve precise control of the moving direction of the glass carrier body 102. This control mechanism not only improves the stability and accuracy of the system, but also enables the glass carrier body 102 to achieve flexible and efficient movement in a complex transmission system.

[0042] A set of cylinders 301 is fixed to the upper and lower ends of the body 201. Each set of cylinders 301 is arranged side by side along the length of the body 201, with the upper and lower sets of cylinders 301 facing each other. An electromagnet 302 is fixed to the side of the cylinder 301 closest to the glass carrier body 102. The electromagnet 302 cooperates with the glass carrier body 102. A photoelectric sensor 209 is fixed to the upper end of the body 201, close to the glass carrier body 102. The photoelectric sensor 209 is located longitudinally between each set of cylinders 301.

[0043] When the glass carrier body 102 carrying the glass arrives at the positioning station on the fuselage body 201 where the cylinder 301 is installed, the photoelectric sensor 209 detects the position of the glass carrier body 102. When the glass carrier body 102 is detected to be in position, the controller controls the FTS coil 207 and the FTS magnetic plate 103 to be de-energized, controls the electromagnet 302 to operate, and drives the cylinder 301 to extend, so that the electromagnet 302 extends and attracts the glass carrier body 102, thereby fixing the position of the glass carrier body 102.

[0044] The glass carrier body 102 is positioned by utilizing the magnetic attraction of the electromagnet 302 . During positioning, the electromagnet 302 does not contact the outer wall of the glass carrier body 102 to generate debris, thereby further improving the cleanliness during transportation.

[0045] In summary, the present application utilizes magnetic levitation adsorption technology to offset the load of the glass carrier. The FTS coil 207 in the device is fixed as a stator, and the FTS magnetic plate 103 is bound together with the glass carrier body 102 as a mover, thereby getting rid of the constraints of the cables at the mobile end that are caused by the movement of the mover. This makes it easy to realize arbitrary and diversified route design, and uses magnetic fixation instead of traditional clamping fixation to reduce contact friction, reduce the generation of debris, and improve product quality.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
