Description

Technical Field

[0001] The utility model relates to the field of production and transportation of flexible screens, and in particular to a flexible screen rotation mechanism. Background Art

[0002] The production of flexible screens is generally carried out in dust-free workshops, because dust in the air will affect the quality of the final screens produced. Therefore, in order to further ensure the air cleanliness in the flexible screen production environment, a sealed glass cover is additionally installed outside the flexible screen production line in the dust-free workshop to separate the flexible screen production line from the dust-free workshop.

[0003] However, the production of screens is often not completed on one production line, so sometimes it is necessary to transfer the flexible screen to another production line through a transfer mechanism. This also requires a rotating mechanism to adjust the position and direction of the flexible screen to ensure that the flexible screen can enter another production line in a predetermined orientation.

[0004] However, the rotation and transfer process are all carried out in the workshop outside the production line, which will have a lot of contact with the air in the workshop and easily get some dust. Moreover, it is too troublesome to transfer and rotate the screen one by one, and if it is a batch operation, multiple flexible screens need to be stacked, but multiple flexible screens cannot be directly stacked together, and need to be separated in the middle, which is difficult to operate. Utility Model Content

[0005] In view of this, the purpose of the utility model is to propose a flexible screen rotation mechanism to solve the technical problems in the prior art that the flexible screens are difficult to stack and are easily contaminated with dust when adjusting the orientation and transporting the flexible screens.

[0009] A drive motor as a power source, the drive motor is fixedly installed at the bottom of the transfer storage box;

[0010] The upper and lower ends of the transmission connecting rod are fixedly connected with helical gears. The helical gear at the lower end of the transmission connecting rod meshes with the gear on the output shaft of the driving motor, and the helical gear at the upper end of the transmission connecting rod meshes with the connecting gear.

[0011] Furthermore, a plurality of compartments are arranged in the storage cabinet, and each compartment is composed of two adjacent layers of a plurality of support rollers located in the same plane, and the interval between two adjacent layers of support rollers is greater than the thickness of the flexible screen.

[0012] Furthermore, screw rods are provided on both sides of the storage cabinet, and the lower ends of the screw rods are connected to the output shaft of the lifting motor. Connecting pieces are fixedly connected to both sides of the storage cabinet, and the connecting pieces are threadedly connected to the screw rods.

[0013] Furthermore, the upper end of the screw rod is rotatably connected to the top plate of the transfer storage box, and the lifting motor is fixedly connected to the bottom plate of the transfer storage box.

[0014] Furthermore, the transmission connecting rod and the driving rod are both rotatably connected to the support frame, and the support frame is fixedly connected in the transfer storage box.

[0015] Furthermore, an entrance and exit for the flexible screen to enter and exit is provided on the side wall of the transfer storage box, and the top of the driving wheel is at the same height as the entrance and exit.

[0025] Specific implementation method and principle

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0027] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] The first aspect of the utility model is as follows Figure 1 and Figure 2 As shown, the main body of the utility model includes a rotating support plate 100 for rotating and changing the direction of the flexible screen 01, a transfer storage box 101 for storing the flexible screen 01 and a transfer cart 102 for transfer, wherein the transfer storage box 101 is rotatably connected to the upper end of the transfer cart 102 through the rotating support plate 100.

[0029] When the orientation of the flexible screen 01 needs to be changed by rotation, the rotating support plate 100 drives the transfer storage box 101 with the flexible screen 01 installed to rotate, so that the inlet and outlet 103 on the side wall of the transfer storage box 101 can be aligned with the entrance of the next growth line (when assembling the growth line, it is necessary to ensure that the inlet and outlet positions are at the same height). Since the transfer storage box 101 storing the flexible screen 01 is in a basically sealed state, only an inlet and outlet 103 for the flexible screen 01 to enter and exit is provided on the side wall of the transfer storage box 101. Therefore, when the rotating support plate 100 rotates to adjust the orientation of the flexible screen 01, the flexible screen 01 will not have too much contact with the air in the workshop, thereby minimizing the pollution of dust in the air.

[0030] The focus of this program is to Figure 3 , Figure 4 and Figure 5 As shown, the transport storage box 101 is provided with a storage cabinet 104 and a driving assembly for controlling the entry and exit of the flexible screen 01. The driving assembly is composed of a driving wheel 114 for driving the flexible screen 01 to move, a driving motor 109 as a power source, and a transmission connecting rod 111 with bevel gears fixedly connected at the upper and lower ends.

[0031] The driving wheel 114 is fixedly connected to both ends of the driving rod 112, and the driving rod 112 is also fixedly connected to a connecting gear 113. The driving motor 109 is fixedly installed at the bottom of the transfer storage box 101. The bevel gear at the lower end of the transmission connecting rod 111 meshes with the gear on the output shaft of the driving motor 109, and the bevel gear at the upper end of the transmission connecting rod 111 meshes with the connecting gear 113. Therefore, after the driving motor 109 works, the power is transferred to the driving rod 112 through the transmission connecting rod 111, so that the driving rod 112 rotates, thereby ensuring that the driving wheel 114 is always in a rotating state.

[0032] The transmission connecting rod 111 and the driving rod 112 are both rotatably connected to the support frame 110, and the support frame 110 is fixedly connected in the transport storage box 101. The support frame 110 is used to ensure the stability of the driving wheel 114, so the driving wheel 114 can only rotate without shaking in other positions.

[0033] Therefore, the inlet and outlet 103 on the side wall of the transfer storage box 101 is aligned with the production line outlet. When the flexible screen 01 comes out of the production line outlet, the flexible screen 01 enters the transfer storage box 101 through the inlet and outlet 103 and falls on the driving wheel 114. The driving wheel 114 in a rotating state drives the transportation and transports the flexible screen 01 to the storage cabinet 104.

[0034] On the other hand, Figure 3As shown, a plurality of compartments are arranged in the storage cabinet 104, each compartment is composed of two adjacent layers of a plurality of support rollers 108 in the same plane, and the interval between two adjacent layers of support rollers 108 is greater than the thickness of the flexible screen 01, and the support rollers 108 can rotate to facilitate the entry and exit of the flexible screen 01. Screws 106 are arranged on both sides of the storage cabinet 104, and the lower end of the screw 106 is connected to the output shaft of the lifting motor 107. Connectors 105 are fixedly connected on both sides of the storage cabinet 104, and the connectors 105 are threadedly connected to the screws 106. The upper end of the screw 106 is rotatably connected to the top plate of the transfer storage box 101, and the lifting motor 107 is fixedly connected to the bottom plate of the transfer storage box 101.

[0035] The storage cabinet 104 that can be lifted and lowered cooperates with the driving assembly. After a flexible screen 01 enters the storage cabinet 104 and is placed in a suitable compartment, and before the next flexible screen 01 comes out of the growth line, the lifting motor 107 drives the screw 106 to rotate, and the screw 106 rotates through the connector 105 to drive the storage cabinet 104 to drop or rise a standard height (i.e., the height of a compartment). Then wait for the next flexible screen 01 to enter until the compartment in the storage cabinet 104 is full of flexible screens 01. This set of mechanisms can automatically stack multiple flexible screens 01 together, and there is no contact between the flexible screens 01, which is simple and convenient to operate. The rotating support plate 100 can adjust the orientation of multiple flexible screens 01 in batches.

[0036] After the loading of the flexible screen 01 is completed, the transfer cart 102 carries the transfer storage box 101 to transport multiple flexible screens 01 in batches to the next growth line, thus completing the batch rotation adjustment of the orientation of the flexible screen 01 and the transfer of the flexible screen 01. During the whole process, the flexible screen 01 will not have too much contact with the air in the workshop, reducing the pollution of dust in the air. DETAILED DESCRIPTION

[0037] Before the flexible screen 01 rolls off a production line, the transfer storage box 101 is moved to the production line exit position in advance by the transfer cart 102, so that the inlet and outlet 103 on the side wall of the transfer storage box 101 is aligned with the production line exit (when assembling the growth line, it is necessary to ensure that the inlet and outlet positions of each growth line are at the same height), and then the storage cabinet 104 is adjusted to the initial position by the lifting motor 107.

[0038] The storage cabinet 104 is generally adjusted to the initial position by raising the storage cabinet 104 to the highest position so that the lower compartments in the storage cabinet 104 are at the same height as the entrance 103. Alternatively, the storage cabinet 104 is raised to the lowest position so that the upper compartments in the storage cabinet 104 are at the same height as the entrance 103. The highest position of the storage cabinet 104 will be used as its initial position below.

[0039] After the above preparations are completed, the production line drives the flexible screen 01 out of the production line exit and into the inlet and outlet 103 on the side wall of the transfer storage box 101. Since the top of the driving wheel 114 is at the same height as the inlet and outlet 103, and the driving wheel 114 is always in a rotating state, the flexible screen 01 will fall on the driving wheel 114 when it enters the transfer storage box 101 through the inlet and outlet 103. The driving wheel 114 in a rotating state plays a role in driving the transportation, and transports the flexible screen 01 to the lowest compartment in the storage cabinet 104, where the support roller 108 at the bottom of the compartment can rotate to facilitate the entry and exit of the flexible screen 01.

[0040] After the first flexible screen 01 enters the storage cabinet 104 and is placed in the bottom compartment, and before the next flexible screen 01 comes out of the production line, the lifting motor 107 drives the screw 106 to rotate, and the rotation of the screw 106 drives the storage cabinet 104 to descend or rise a standard height through the connecting piece 105, so that the second compartment at the bottom is at the same height as the import and export 103, and then the second flexible screen 01 is loaded, and so on, until the compartments in the storage cabinet 104 are filled with flexible screens 01.

[0041] Then, the transfer cart 102 transports multiple flexible screens 01 in batches with the transfer storage box 101 to the entrance of the next growth line. Finally, the rotating support plate 100 drives the transfer storage box 101 loaded with the flexible screen 01 to rotate, so that the inlet and outlet 103 on the side wall of the transfer storage box 101 can be aligned with the entrance of the next growth line. The drive motor 109 then drives the drive wheel 114 to reverse, so that the flexible screen 01 can exit the transfer storage box 101 in the same way as when it entered the transfer storage box 101, and finally enter the next growth line. After the first flexible screen 01 goes out, the storage cabinet 104 decreases at a frequency set in advance, so that each flexible screen 01 enters the next growth line one by one.

[0042] Based on the above, the storage cabinet 104 for stacking flexible screens 01 of the utility model is provided with a plurality of compartments, each of which is composed of a plurality of support rollers 108 in two adjacent layers on the same plane, and the support rollers 108 can rotate to facilitate the entry and exit of the flexible screen 01, and the storage cabinet 104 can be raised and lowered, so it cooperates with the fixed position of the inlet and outlet 103 and the driving wheel. The transfer storage box 101 for storing the flexible screen 01 is in a basically sealed state, and only an inlet and outlet 103 for the flexible screen 01 to enter and exit is provided on the side wall of the transfer storage box 101. Therefore, during the rotation and orientation adjustment and transportation process, it can avoid contact with the air as much as possible, reducing dust pollution.
