DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 3-Figure 7, which is the first embodiment of the present invention, and this embodiment provides a feeding and conveying device for optical film lamination. The feeding and conveying device for optical film lamination includes a discharge assembly 100 and a base 101.

[0035] A mounting seat is provided on the base 101 for mounting and fixing the discharge roller. At the same time, a driving device (not shown in the figure) is provided on the base 101 for driving the discharge roller to rotate so that the discharge roller can discharge the raw material. There are two discharge rollers, one on the top of the base 101 and the other on the top of the frame. A mounting seat and a driving device are also provided on the top of the frame. The two discharge rollers discharge the two types of membranes that need to be bonded respectively.

[0036] The material replacement assembly 200 is arranged on the base 101, including a lifting member 201, which is arranged on the top of the base 101, and includes a support plate 201a, the support plate 201a is fixed to the top of the base 101, a guide rail 201b is fixed on one side of the support plate 201a, a slider 201c is slidably connected in the guide rail 201b, a support sleeve 201d is fixed on one side of the slider 201c, a support sleeve 201d is rotatably connected to the outer side of the support sleeve 201d through a bearing to connect to a support arm 201e, a connecting column 201f is fixed in the support arm 201e, and a connecting mechanism 201g is fixed at the end of the support arm 201e.

[0037] There are two groups of lifting members 201, which are respectively located on both sides of the top of the base 101. The two groups of lifting members 201 simultaneously lift both sides of the unloading roller upward, thereby preventing the unloading roller from deviating during the rising process.

[0038] The slider 201c is T-shaped, and the connecting column 201f is used to connect and fix the two support arms 201e. The support arm 201e is connected and fixed to the discharge roller through the connecting mechanism 201g, so that the support arm 201e can lift the discharge roller upward when moving upward.

[0039] When the raw material is replaced, the feeding roller is inserted into the paper tube inside the raw material, and then the inside of the feeding roller is inflated to fix the feeding roller to the original paper tube. At this time, the slider 201c is moved to the end of the guide rail 201b, and the support arm 201e is rotated downward to a vertical state, and then the support arm 201e is connected to the feeding roller through the connecting mechanism 201g. At this time, the slider 201c is moved, and the support arm 201e is driven to move by the slider 201c. When the support arm 201e moves, it will drive the feeding roller to move upward. When the feeding roller moves to the same height as the mounting seat on the base 101, it will stop moving upward. At this time, the slider 201c will drive the support arm 201e and the feeding roller to move horizontally until the feeding roller moves to the inside of the mounting seat, and then the feeding roller can be fixed by the mounting seat. In this way, the replacement of the raw material is completed, and the raw material will not be damaged during the lifting process. At the same time, the installation of the feeding roller can be accurately positioned.

[0040] The connecting mechanism 201g is composed of two semicircular ferrules, one of which is fixed to the end of the support arm 201e, and one side of the two ferrules is rotatably connected by a rotating shaft. The movable ferrules can be rotated to open and close, so that the discharge roller can be wrapped inside by the two ferrules, and the two ferrules are connected and fixed by bolts, thereby completing the connection between the support arm 201e and the discharge roller.

[0041] The material replacement assembly 200 also includes a guide member 202, which is arranged on the guide rail 201b, including a support rod 202a, the support rod 202a is located on one side of the guide rail 201b, a support block 202b is fixed to one side of the support rod 202a, a support column 202c is inserted into the support block 202b, a mounting block 202d is fixed on the guide rail 201b, both ends of the support column 202c are respectively fixed to the two mounting blocks 202d, and the support rod 202a is inclined.

[0042] There are two groups of guide members 202, corresponding to the two groups of lifting members 201. There are two groups of structures in one group of guide members 202, which are respectively located at the guide rail 201b and the top and bottom. The two support rods 202a are both inclined and face in opposite directions.

[0043] The mounting block 202d is used to fix the support column 202c, and the support block 202b and the support rod 202a are supported and positioned through the support column 202c.

[0044] When the support arm 201e is in a vertical state and connected to the discharge roller, the support arm 201e contacts the end of the support rod 202a at the bottom. When the slider 201c drives the support arm 201e to move, the support arm 201e is blocked by the support rod 202a and cannot move, so it will tilt and drive the discharge roller to move upward. When the support arm 201e tilts to a certain angle, it will be parallel to the support rod 202a and press on the top of the support rod 202a. At this time, the support arm 201e is supported by the support rod 202a. At the same time, the discharge roller and the mounting seat are at the same height. At this time, when the slider 201c drives the support arm 201e to move, the support arm 201e will push the support rod 202a to move. At this time, the support arm 201e will not continue to tilt, and will remain parallel to the support rod 202a to drive the discharge roller to move until the discharge roller enters the inside of the mounting seat. At this time, the raw material placed on the top of the base 101 is replaced.

[0045] When replacing the raw materials on the top of the frame, when the slider 201c drives the support arm 201e to move, the support arm 201e will drive the discharge roller to rotate upward. As the slider 201c moves, the support arm 201e will continue to rotate. When the support arm 201e contacts the support rod 202a at the top of the guide rail 201b, the support arm 201e will stop rotating and support the support arm 201e through the support rod 202a. At the same time, the discharge roller and the mounting seat on the top of the frame are at the same height. When the slider 201c continues to drive the support arm 201e to move, the discharge roller can be driven by the support arm 201e to enter the mounting seat on the top of the frame, thereby completing the replacement of the high raw materials.

[0046] The support arm 201e and the support rod 202a are both made of high-strength materials and can stably support the raw materials.

[0047] The material replacement assembly 200 also includes a transmission member 203, which is arranged on one side of the support plate 201a, including a gear 203a, the gear 203a is fixed to the outside of the connecting column 201f, a rack 203b is arranged at the bottom of the gear 203a, a positioning plate 203c is fixed at the bottom of the rack 203b, and a stabilizing column 203d is fixed on one side of the support plate 201a, and the stabilizing column 203d is movably connected with the positioning plate 203c.

[0048] The positioning plate 203c cooperates with the stabilizing column 203d to support and position the rack 203b, and by lengthening the length of the positioning plate 203c, it is possible to prevent the support rod 202a from contacting the stabilizing column 203d when moving, thereby preventing the movement of the support rod 202a. The connection between the stabilizing column 203d and the inside of the positioning plate 203c is relatively tight, and the positioning plate 203c will not move easily without interference from external human forces.

[0049] When the raw material on the top of the base 101 needs to be replaced, the rack 203b is pulled to one side to separate it from the gear 203a. When the raw material on the top of the frame needs to be replaced, the rack 203b is meshed with the gear 203a. At this time, when the support arm 201e moves, it will drive the gear 203a to rotate on the top of the rack 203b, so that the support arm 201e can rotate upward and drive the discharge roller to rotate upward to the height of the mounting seat on the top of the frame. When the support arm 201e contacts the support rod 202a above, the gear 203a will move to the end of the rack 203b and separate from the rack 203b, so that the support arm 201e can stop rotating during the movement.

[0050] The protective component 300 is arranged on the connecting column 201f, and includes a movable plate 301. The movable plate 301 is located on the inner side of the supporting sleeve 201d. A fixed column 302 is fixed to the bottom of the movable plate 301. A slot 201f-1 is provided on the connecting column 201f. One end of the fixed column 302 is inserted into the slot 201f-1. A fixed plate 303 is fixed to one end of the connecting column 201f. A sensing ball 304 is movably connected in the slot 201f-1. One side of the sensing ball 304 is in contact with the fixed plate 303. A first spring 305 is sleeved on the outer side of the connecting column 201f. The two ends of the first spring 305 are respectively fixed to the inner wall of the slot 201f-1 and the fixed plate 303. A clamping block 306 is fixed to one side of the movable plate 301. A clamping slot 201d-1 is provided on the supporting sleeve 201d. The clamping block 306 cooperates with the clamping slot 201d-1.

[0051] There are two groups of protective components 300, which are located at both ends of the connecting column 201f respectively. There are two structures in the protective components 300, which are located on both sides of the connecting column 201f respectively. There are multiple slots 201d-1, which are evenly distributed in a ring shape on the support sleeve 201d. The sensing ball 304 has a certain weight.

[0052] When the support arm 201e rotates at a normal speed and lifts the raw materials, the connecting column 201f rotates at a slower speed. The first spring 305 applies a thrust to the fixed plate 303, and the fixed plate 303 drives the fixed column 302 and the movable plate 301 to move, so that the movable plate 301 drives the block 306 to be separated from the slot 201d-1. At this time, the connecting column 201f can rotate at a normal speed.

[0053] When the support arm 201e accidentally falls downward quickly during the process of lifting the raw material, the connecting column 201f will generate a large centrifugal force. The induction ball 304 will push the fixed plate 303 to move under the action of the centrifugal force, and push the fixed column 302 and the movable plate 301 to move through the fixed plate 303, so that the movable plate 301 drives the block 306 to engage with the slot 201d-1. Through the cooperation of the two, the connecting column 201f can be locked, so that the connecting column 201f and the support arm 201e cannot continue to rotate, thereby avoiding the support arm 201e and the raw material falling rapidly downward, which may cause personal injury and damage to the raw materials.

[0054] The block 306 and the fixing column 302 are both made of high-strength material, which can prevent the block 306 from being broken due to the impact force generated when the block 306 is engaged with the slot 201d-1.

[0055] Example 2

[0056] Reference Figure 3-Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0057] Specifically, a threaded rod 201h is rotatably connected to the guide rail 201b via a bearing, and the threaded rod 201h is threadably connected to the inner thread of the slider 201c. A motor 201i is fixed to one side of the guide rail 201b, and the output shaft of the motor 201i is fixed to the threaded rod 201h.

[0058] The motor 201i is used to drive the threaded rod 201h to rotate. When the threaded rod 201h rotates, it can drive the slider 201c to move.

[0059] Specifically, the material replacement assembly 200 also includes a locking piece 204, which is arranged in the support rod 202a, including a limiting column 204a, a movable groove 202a-1 is opened in the support rod 202a, the limiting column 204a is located in the movable groove 202a-1, a limiting hole 202c-1 is opened on the support column 202c, the limiting column 204a is engaged with the limiting hole 202c-1, a second spring 204b is fixed to one end of the limiting column 204a, and one end of the second spring 204b is fixed to the inner wall of the movable groove 202a-1.

[0060] When the limit column 204a is engaged with the limit hole 202c-1, the position of the support rod 202a and the support block 202b can be locked to prevent the slider 201c from driving the support arm 201e to move, and the support arm 201e contacts the support rod 202a, causing the support rod 202a to move, thereby preventing the support arm 201e from being tilted, thereby driving the raw material to be lifted upward. The second spring 204b is used to apply a thrust to the limit column 204a, so that the limit column 204a and the limit hole 202c-1 are more tightly engaged.

[0061] Specifically, the support rod 202a is plugged with an extrusion rod 204c, the limiting column 204a is provided with a force groove 204a-1, the extrusion rod 204c matches with the force groove 204a-1, and the inner wall of the force groove 204a-1 is inclined.

[0062] One end of the extrusion rod 204c is located on the outside of the support rod 202a. When the support arm 201e rotates to a state parallel to the support rod 202a and presses on the top of the support rod 202a, the support arm 201e will press the extrusion rod 204c downward and make the extrusion rod 204c squeeze the inclined surface of the inner wall of the force groove 204a-1. The cooperation between the two drives the limit column 204a to move, so that the limit column 204a is separated from the limit hole 202c-1, thereby releasing the restriction on the support rod 202a and the support block 202b, so that the support arm 201e can push the support rod 202a to move after tilting at a specified angle.

[0063] Specifically, a third spring 202e is sleeved on the outer side of the support column 202c, and two ends of the third spring 202e are respectively fixed to the support block 202b and the mounting block 202d.

[0064] When the support block 202b moves, it will stretch the third spring 202e. When the support arm 201e is separated from the support rod 202a, the support block 202b and the support rod 202a can be pulled to reset by the third spring 202e.

[0065] Specifically, the bottom of the guide rail 201b is rotatably connected to a rotating rod 201b-1 via a rotating shaft, and the top of the rotating rod 201b-1 contacts the supporting arm 201e and supports the supporting arm 201e.

[0066] After the replacement of raw materials is completed, the support arm 201e is rotated to a state parallel to the guide rail 201b, and the rotating rod 201b-1 is rotated to the bottom of the support arm 201e to support the support arm 201e, so as to prevent the support arm 201e from swinging randomly during operation.

[0067] Example 3

[0068] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0069] Specifically, the bottom end of the support rod 202a is rotatably connected to a pulley 202a-2 via a rotating shaft.

[0070] Only the support rod 202a at the bottom is provided with a pulley 202a-2 for reducing the friction with the support arm 201e, so that the support arm 201e can rotate more smoothly.

[0071] Specifically, a first unloading roller 102 is disposed on the top of the base 101 , a frame 103 is disposed on one side of the base 101 , and a second unloading roller 104 is disposed on the top of the frame 103 .

[0072] The first unloading roller 102 and the second unloading roller 104 respectively support two raw materials to be bonded and unload the two raw materials.

[0073] Specifically, a guide roller 105 is disposed inside the base 101 .

[0074] The guide roller 105 is used to position the discharged film.

[0075] Specifically, it also includes a laminating component 400 , which is arranged on the frame 103 , including a squeezing roller 401 , the squeezing roller 401 is arranged on one side of the frame 103 , and a winding roller 402 is arranged inside the frame 103 .

[0076] There are two squeezing rollers 401 arranged up and down, which are used to press the two laminated film sheets and roll up the laminated film sheets through the winding roller 402. This is the prior art and will not be elaborated in detail in this solution. Those skilled in the art can clearly understand the working principle.

[0077] In summary, the feeding and conveying equipment for optical film bonding has the following advantages:

[0078] 1. When replacing raw materials, the position of the unloading roller can be quickly located;

[0079] 2. The raw materials will not be damaged when they are lifted upwards;

[0080] 3. When the raw material is lifted to a high place and falls downward quickly due to accident, the protection component 300 can be used to lock the support arm 201e that falls downward, so as to avoid damage to the raw material and injury to personnel;

[0081] Fourth, a set of material changing components 200 can be used to change the raw materials of the unloading rollers at two different positions, thereby reducing the space occupied by the equipment and making the layout of the production line more compact and reasonable.

[0082] During use, when the raw material on the top of the base 101 needs to be replaced, the rack 203b is pulled to one side to separate it from the gear 203a, and then the motor 201i is started to drive the threaded rod 201h to rotate. When the threaded rod 201h rotates, it drives the slider 201c to move to the end of the guide rail 201b, and the support arm 201e is rotated downward to a vertical state, and then the support arm 201e is connected to the material discharge roller through the connecting mechanism 201g.

[0083] Then start the motor 201i again to drive the threaded rod 201h to rotate in the opposite direction, so that the threaded rod 201h drives the slider 201c to move in the opposite direction, and drives the support arm 201e to move through the slider 201c. When the support arm 201e is moving, the support arm 201e is blocked by the support rod 202a and cannot move, so it will tilt and drive the discharge roller to move upward. When the support arm 201e tilts at a certain angle, it will be parallel to the support rod 202a and press on the top of the support rod 202a. At this time, the support arm 201e is supported by the support rod 202a. At the same time, the discharge roller and the mounting seat are at the same height. At this time, when the slider 201c drives the support arm 201e to move, the support arm 201e will push the support rod 202a to move. At this time, the support arm 201e will not continue to tilt, and will remain parallel to the support rod 202a to drive the discharge roller to move until the discharge roller enters the inside of the mounting seat.

[0084] When the raw material on the top of the frame needs to be replaced, the rack 203b is meshed with the gear 203a. At this time, the support arm 201e will drive the gear 203a to rotate on the top of the rack 203b when it moves, so that the support arm 201e can rotate upward and drive the discharge roller to rotate upward to the height of the mounting seat on the top of the frame. At this time, the support arm 201e will contact the support rod 202a at the top of the guide rail 201b, and the gear 203a will move to the end of the rack 203b and separate from the rack 203b, so that the support arm 201e stops rotating during the movement. At the same time, the discharge roller is at the same height as the mounting seat on the top of the frame. When the slider 201c continues to drive the support arm 201e to move, the discharge roller can be driven by the support arm 201e to enter the mounting seat on the top of the frame, thereby completing the replacement of the high raw materials.
