Description

Technical Field

[0001] The invention belongs to the technical field of liquid crystal panel production, and in particular relates to a glue cutting mechanism and a glue sticking device containing the glue cutting mechanism. Background Art

[0002] During the production of liquid crystal panels, it is necessary to paste and cut ACF glue on the glue sticking device, and the ACF glue is rolled to the glue cutting mechanism for cutting through the mechanism. The existing glue cutting mechanism usually includes a glue cutting blocking head, a first cylinder for driving the glue cutting blocking head to move, a glue cutting knife head located below the glue cutting blocking head, and a second cylinder for driving the glue cutting knife head to move up and down. When cutting glue, the glue cutting blocking head is sent to the glue cutting position by the first cylinder, and the glue cutting knife head is driven to rise by the second cylinder to perform the glue cutting action.

[0003] However, in actual production, since the entire gluing device has a compact space and the glue cutting mechanism occupies a large space, the entire gluing device does not have much operating space, maintenance or tool changing is inconvenient, the tool changing efficiency is poor, and the two cylinders act separately, the smoothness of the gluing action is low, and the efficiency is unstable. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved glue cutting mechanism, which greatly saves space and enables the entire glue sticking device to provide more operating space, facilitate maintenance and tool changing, and increase tool changing efficiency.

[0005] The second object of the present invention is to provide a glue sticking device, which has more operating space, is convenient for maintenance and tool change, and has high production efficiency.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A rubber cutting mechanism comprises a frame, a rubber cutting blocking head assembly having a rubber cutting blocking head, and a rubber cutting knife head assembly having a rubber cutting knife head, and the rubber cutting mechanism further comprises:

[0008] a driving unit, which is arranged on the frame;

[0009] A connecting assembly, which is slidably connected to the frame along a first direction, and the connecting assembly slides under the drive of the driving unit;

[0010] One of the rubber cutting blocking head assembly and the rubber cutting knife head assembly is slidably connected to the frame along the first direction, and the other is slidably connected to the one of the components along the second direction, and the first direction and the second direction intersect;

[0011] The rubber cutting mechanism further includes a limiting member for limiting the sliding of the one component on the frame and a first elastic member whose two ends are respectively connected to the connecting assembly and the one component;

[0012] When the driving unit drives the connecting assembly to slide forwardly along the first direction on the frame, the rubber cutting blocking head assembly and the rubber cutting knife head assembly slide forwardly along the first direction together under the elastic force of the first elastic member until one of the components collides with the limiting member, and the connecting assembly continues to slide forwardly along the first direction driven by the driving unit, driving the other component to slide along the second direction and bringing the rubber cutting knife head and the rubber cutting blocking head closer to each other to perform rubber cutting.

[0013] In the present invention, "sliding connection" means that one of the two structures can be directly slidably connected to the other structure, or can be indirectly slidably connected through an intermediate medium, such as by fixing a slide rail on one structure and fixing a slider on the other structure, and slidingly connecting the two structures through the cooperation of the slide rail and the slider.

[0014] Furthermore, the one component is the rubber cutting blocking head assembly, and the other component is the rubber cutting knife head assembly.

[0015] According to some embodiments of the present invention, the rubber cutting mechanism also includes a second elastic member whose two ends are respectively connected to the rubber cutting blocking head assembly and the rubber cutting knife head assembly, and when the rubber cutting knife head assembly slides along the second direction and brings the rubber cutting knife head and the rubber cutting blocking head closer to each other, the second elastic member is compressed; when the driving unit drives the connecting assembly to slide in the opposite direction along the first direction on the frame, the rubber cutting knife head assembly slides along the second direction under the elastic force of the second elastic member and moves the rubber cutting knife head and the rubber cutting blocking head away from each other.

[0016] Furthermore, the rubber cutting mechanism also includes a hook claw arranged on the connecting assembly. When the driving unit drives the connecting assembly to continue sliding in the opposite direction of the first direction on the frame, the hook claw hooks the rubber cutting blocking head assembly to make the rubber cutting knife head assembly and the rubber cutting blocking head assembly slide in the opposite direction of the first direction together.

[0017] According to some embodiments of the present invention, when the connecting component continues to slide forwardly along the first direction under the drive of the driving unit, driving the rubber cutting knife head assembly to slide along the second direction and making the rubber cutting knife head and the rubber cutting blocking head approach each other, the connecting component contacts the rubber cutting knife head assembly and changes position with the rubber cutting knife head assembly.

[0018] In the present invention, the connecting component is in contact with the rubber cutting knife head component. Here, "contact" means that the connecting component is in direct contact with the rubber cutting knife head component, or that the connecting component is in indirect contact with the rubber cutting knife head component through an intermediate medium, such as indirectly contacting the rubber cutting knife head component through a roller or a slider arranged on the connecting component.

[0019] In some preferred and specific embodiments, the connecting component contacts the rubber cutting knife head assembly through a guide bevel provided on at least one of the two contacting components, and the guide bevel intersects with the first direction. When the connecting component continues to slide forward along the first direction under the drive of the driving unit, the guide bevel drives the rubber cutting knife head assembly to slide along the second direction and brings the rubber cutting knife head and the rubber cutting blocking head closer to each other.

[0020] In some preferred and specific embodiments, the connecting assembly is pivotally connected to a roller via a roller shaft, and the roller is in contact with the guide inclined surface.

[0021] Furthermore, the first direction is perpendicular to the second direction.

[0022] Furthermore, the driving unit is a cylinder.

[0023] According to some embodiments of the present invention, the rubber cutting mechanism further comprises a hook arranged on the connecting assembly and a second elastic member having two ends respectively connected to the rubber cutting blocking head assembly and the rubber cutting knife head assembly;

[0024] The rubber cutting mechanism has at least three working states, which are an initial working state, a knife-feeding working state and a rubber cutting working state;

[0025] When the rubber cutting mechanism is in an initial working state, the connecting assembly, the rubber cutting blade head, and the rubber cutting blocking head are respectively located at initial positions, the first elastic member and the second elastic member are respectively in a relaxed state, one component is separated from the limiting member, and the connecting assembly is in contact with the other component;

[0026] When the rubber cutting mechanism switches from the initial working state to the cutting working state, the driving unit drives the connecting assembly to slide forward along the first direction, and the rubber cutting blocking head assembly and the rubber cutting knife head assembly slide forward along the first direction together under the elastic force of the first elastic member until one of the components abuts against the limiting member, at which time, the rubber cutting knife head and the rubber cutting blocking head both extend out of the frame, and the connecting assembly contacts the other component and does not change position;

[0027] When the rubber cutting mechanism switches from the cutting working state to the rubber cutting working state, the driving unit drives the connecting component to continue to slide in the first direction and compress the first elastic member, the connecting component contacts the other component and changes position, drives the other component to slide in the second direction and compress the second elastic member, and the rubber cutting knife head and the rubber cutting blocking head approach each other;

[0028] When the rubber cutting mechanism switches from the rubber cutting working state to the initial working state, the driving unit drives the connecting assembly to slide in the opposite direction along the first direction, and the other component slides in the opposite direction along the second direction under the elastic force of the second elastic component, and the rubber cutting knife head and the rubber cutting blocking head move away from each other. The driving unit drives the connecting assembly to continue to slide in the opposite direction along the first direction, and the hook hooks the one component so that the rubber cutting knife head assembly and the rubber cutting blocking head assembly slide in the opposite direction along the first direction together until the connecting assembly, the rubber cutting knife head and the rubber cutting blocking head all return to the initial position.

[0029] The second technical solution adopted by the present invention is: a glue sticking device, comprising a glue cutting mechanism, and the glue cutting mechanism is as described above.

[0030] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0031] The rubber cutting mechanism of the present invention can realize the two actions of cutting and cutting by a driving unit in combination with a connecting assembly and an elastic member. Compared with the traditional rubber cutting mechanism, it greatly saves space, so that the entire rubber laminating device can provide more operating space, and is convenient for maintenance and knife replacement. At the same time, the line layout is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The present invention is further described below with reference to the accompanying drawings and specific embodiments:

[0043] like Figures 1 to 15 The portable rubber cutting mechanism shown includes a frame 1, a rubber cutting blocking head assembly 2 having a rubber cutting blocking head 2a, a rubber cutting knife head assembly 3 having a rubber cutting knife head 3a, a driving unit 4 arranged on the frame 1, and a connecting assembly 5 slidably connected to the frame 1 along a first direction, wherein the rubber cutting blocking head assembly 2 is slidably connected to the frame 1 along the first direction, the rubber cutting knife head assembly 3 is slidably connected to the rubber cutting blocking head assembly 2 along the second direction, the connecting assembly 5 is connected to the driving unit 4 and slides under the drive of the driving unit 4, the first direction and the second direction intersect, and in this example, the first direction and the second direction are basically perpendicular.

[0044] The rubber cutting mechanism also includes a limiter 8 arranged on the frame 1 and used to limit the sliding of the rubber cutting blocking head assembly 2 on the frame 1, and a first elastic member 6 whose two ends are respectively connected to the connecting assembly 5 and the rubber cutting blocking head assembly 2, and the first elastic member 6 is a spring.

[0045] based on Figure 5 As shown, the rubber cutting blade head 3a is located below the rubber cutting blocking head 2a, the first direction is the horizontal extension direction, the second direction is the vertical extension direction, and the length extension direction of the first elastic member 6 is substantially parallel to the first direction.

[0046] When the driving unit 4 drives the connecting assembly 5 to slide forward along the first direction on the frame 1, the rubber cutting blocking head assembly 2 and the rubber cutting knife head assembly 3 slide forward along the first direction together under the elastic force of the first elastic member 6, until the rubber cutting blocking head assembly 2 conflicts with the stopper 8, and the cutting is completed. The connecting assembly 5 continues to slide forward along the first direction under the drive of the driving unit 4, driving the rubber cutting knife head assembly 3 to slide forward along the second direction, and the rubber cutting knife head 3a and the rubber cutting blocking head 2a are close to each other to cut rubber. The cutting and cutting actions are completed by the drive of a driving unit 4. Compared with the traditional rubber cutting mechanism, space is saved, and only one driving unit 4 needs to be arranged. The line layout is simple and convenient, and the pipeline and circuit layout of a driving unit are omitted. However, the traditional rubber cutting mechanism needs to arrange two driving units, and the pipeline lines are more, and the space is large, so that the entire rubber sticking device does not have too much operating space, and it is difficult for the hand to reach in, and it is inconvenient to repair and change the knife. However, the present application enables the entire rubber sticking device to provide more operating space, and it is convenient to repair and change the knife. At the same time, one driving unit acts, and the entire production is more stable.

[0047] When the driving unit 4 drives the connecting component 5 to slide forward in the first direction on the frame 1, and the rubber cutting blocking head component 2 and the rubber cutting knife head component 3 slide forward in the first direction together under the elastic force of the first elastic member 6, the connecting component 5 contacts the rubber cutting knife head component 3 and does not change position with the rubber cutting knife head component 3; when the connecting component 5 continues to slide forward in the first direction driven by the driving unit 4 and drives the rubber cutting knife head component 3 to slide forward in the second direction, the connecting component 5 contacts the rubber cutting knife head component 3 and changes position with the rubber cutting knife head component 3. Specifically, a roller 10 is pivotally connected to one end of the connecting assembly 5 close to the rubber cutting blade head assembly 3 through a roller shaft 11, and the roller 10 contacts the rubber cutting blade head assembly 3 through a guide slope 12 provided on the rubber cutting blade head assembly 3, and the guide slope 12 intersects with the first direction. When the connecting assembly 5 continues to slide forward along the first direction under the drive of the driving unit 4, the roller 10 rolls with the guide slope 12, and the guide slope 12 drives the rubber cutting blade head assembly 3 to slide forward along the second direction and brings the rubber cutting blade head 3a and the rubber cutting blocking head 2a closer to each other. The use of the roller 10 rolling in contact with the guide slope 12 can greatly reduce the friction between the guide slope 12 compared to the sliding contact.

[0048] In this example, if Figure 2 As shown, the frame 1 is fixedly provided with a first slide rail 13 extending in a first direction, the connecting assembly 5 is fixedly provided with a first slider 14 that can cooperate with the first slide rail 13 for sliding connection, and the rubber cutting blocking head assembly 2 is fixedly provided with a second slider 15 that can cooperate with the first slide rail 13 for sliding connection. Figure 3 As shown, the limit member 8 is arranged below the frame 1 and close to the rubber cutting blocking head 2a and away from the connection assembly 5. The rubber cutting blocking head assembly 2 has a blocking portion 2b located below the frame 1 that can conflict with or separate from the limit member 8.

[0049] The rubber cutting mechanism also includes a second elastic member 7 whose two ends are respectively connected to the rubber cutting blocking head assembly 2 and the rubber cutting knife head assembly 3, and a hook claw 9 arranged on the connecting assembly 5. The second elastic member 7 is a spring, and the length extension direction of the second elastic member 7 is basically parallel to the second direction. One end of the hook claw 9 has a hook portion 9a, and the rubber cutting blocking head assembly 2 has a matching portion 2c that can cooperate with or separate from the hook portion 9a.

[0050] When the rubber cutting blade assembly 3 moves forward along the second direction and makes the rubber cutting blade head 3a and the rubber cutting blocking head 2a approach each other, the second elastic member 7 is compressed. When the driving unit 4 drives the connecting assembly 5 to slide in the opposite direction along the first direction on the frame 1, the rubber cutting blade assembly 3 slides in the opposite direction along the second direction under the elastic force of the second elastic member 7 and makes the rubber cutting blade head 3a and the rubber cutting blocking head 2a move away from each other; when the driving unit 4 drives the connecting assembly 5 to continue to slide in the opposite direction along the first direction on the frame 1, the hook portion 9a of the hook 9 hooks the matching portion 2c of the rubber cutting blocking head assembly 2 to make the rubber cutting blocking head assembly 2 and the rubber cutting blade assembly 3 slide in the opposite direction along the first direction together.

[0051] In this example, based on Fig.15 As shown, a second slide rail 16 is fixedly provided on the rubber cutting blocking head assembly 2 extending along the second direction, a third slider 17 which can be slidably connected with the second slide rail 16 is fixedly provided on the rubber cutting knife head assembly 3, and the roller 10 abuts against the bottom of the rubber cutting knife head assembly 3.

[0052] In this example, the driving unit 4 is a cylinder having a piston rod, and the piston rod is connected to the connecting assembly 5 .

[0053] The rubber cutting mechanism has at least three working states, namely an initial working state, a knife feeding working state and a rubber cutting working state.

[0054] like Figures 1 to 5 As shown, when the rubber cutting mechanism is in the initial working state, the connecting component 5, the rubber cutting blade head 3a, and the rubber cutting blocking head 2a are respectively located at the initial positions. Figure 5 As shown, the rubber cutting knife head 3a and the rubber cutting blocking head 2a at least partially overlap with the frame 1, the first elastic member 6 and the second elastic member 7 are in a relaxed state, the blocking portion 2b of the rubber cutting blocking head assembly 2 is separated from the limiting member 8, the hook portion 9a of the hook 9 is in contact with the matching portion 2c of the rubber cutting blocking head assembly 2, the roller 10 on the connecting assembly 5 is in contact with the guiding inclined surface 12, and the roller 10 also supports the rubber cutting knife head assembly 3.

[0055] When the rubber cutting mechanism switches from the initial working state to the cutting working state, the driving unit 4 drives the connecting assembly 5 to slide forwardly along the first direction, and the rubber cutting blocking head assembly 2 and the rubber cutting knife head assembly 3 slide forwardly along the first direction under the elastic force of the first elastic member 6, until the blocking portion 2b of the rubber cutting blocking head assembly 2 conflicts with the limiting member 8, the hook portion 9a gradually moves away from the matching portion 2c, and the roller 10 contacts the guide inclined surface 12 and does not change position with the guide inclined surface 12. At this time, the rubber cutting knife head 3a and the rubber cutting blocking head 2a both extend out of the frame 1, as shown in FIG. Figures 6 to 10 shown.

[0056] When the rubber cutting mechanism switches from the feeding working state to the rubber cutting working state, the driving unit 4 drives the connecting assembly 5 to continue to slide in the first direction, the first elastic member 6 is compressed, the roller 10 contacts the guide slope 12 and changes position with the guide slope 12, the guide slope 12 drives the rubber cutting head assembly 3 to slide in the second direction and compress the second elastic member 7, the rubber cutting head 3a and the rubber cutting blocking head 2a approach each other, and rubber cutting is performed. Figures 11 to 15 shown.

[0057] When the rubber cutting mechanism switches from the rubber cutting working state to the initial working state, the driving unit 4 drives the connecting assembly 5 to slide in the opposite direction along the first direction, and the rubber cutting knife head assembly 3 slides in the opposite direction along the second direction under the elastic force of the second elastic member 7, and the rubber cutting knife head 3a and the rubber cutting blocking head 2a move away from each other, and the hook portion 9a of the hook claw 9 gradually approaches the matching portion 2c of the rubber cutting blocking head assembly 2 until it abuts against the matching portion 2c, and the driving unit 4 drives the connecting assembly 5 to continue to slide in the opposite direction along the first direction, and the hook portion 9a of the hook claw 9 hooks the matching portion 2c to drag the rubber cutting blocking head assembly 2 and the rubber cutting knife head assembly 3 to slide in the opposite direction along the first direction until the connecting assembly 5, the rubber cutting knife head 3a and the rubber cutting blocking head 2a all return to their initial positions, completing the knife retraction.

[0058] Through the above-mentioned rubber cutting mechanism, one cylinder can realize the knife feeding, rubber cutting and knife retracting actions, the pipeline route layout is simple and convenient, and it greatly saves space, so that the entire glue sticking device can provide more operating space, and it is convenient for maintenance and knife changing. In addition, one cylinder can realize the knife feeding, rubber cutting and knife retracting actions, which is more stable than two cylinders acting separately.

[0059] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
