Description

Technical Field

[0001] The utility model belongs to the technical field of screen manufacturing, and more specifically relates to a screen pressure maintaining device. Background Art

[0002] Liquid crystal display is a type of flat panel display used for screen display of televisions and computers. The advantages of this display are low power consumption, small size and low radiation. The liquid crystal display uses a liquid crystal solution in two polarized materials. When current passes through the liquid, the crystals will be rearranged to achieve the purpose of imaging. In the production process of liquid crystal displays, in order to make the screen and shell of the liquid crystal display fit together, it is often necessary to use a pressure maintaining device to maintain the pressure.

[0003] At present, a Chinese utility model patent with announcement number CN218082405U discloses a TV screen pressure-maintaining device, which is provided with a frame, on which a conveying mechanism is provided, and the two ends of the conveying mechanism are respectively a loading end and a unloading end. It is characterized in that a pressure-maintaining station is provided on the frame, and a positioning module and a product lifting mechanism are connected to the pressure-maintaining station. A pressure-maintaining mechanism is provided at the upper end of the product lifting mechanism, and a pressure-maintaining lifting module is connected to the pressure-maintaining mechanism, and the pressure-maintaining lifting module drives the pressure-maintaining mechanism to move.

[0004] In the prior art, similar to the positioning module mentioned above, when positioning the product, the positioning plate usually directly contacts the product. In the process of moving the positioning plate, there will be a certain impact force on the product. If the impact force is too large, it will cause damage to the appearance of the product. The contact does not have the effect of reducing the impact. Although buffer materials are pasted in the prior art to avoid damage, the buffer materials will wear out after long-term use and need to be replaced from time to time. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a screen pressure maintaining device, which has the advantage of reducing the impact force of the positioning plate on the product.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A screen pressure-maintaining device comprises a conveyor belt, a frame is installed above the conveyor belt, a pressure-maintaining station is arranged on the frame, a positioning mechanism and a product lifting mechanism are connected to the pressure-maintaining station, a pressure-maintaining mechanism is arranged at the upper end of the product lifting mechanism, a pressure-maintaining lifting module is connected to the pressure-maintaining mechanism, the pressure-maintaining lifting module drives the pressure-maintaining mechanism to move, the positioning mechanism comprises a driving assembly and a mounting plate installed on the driving assembly, a buffer mechanism is installed on the mounting plate to avoid direct contact with the product and mitigate impact.

[0008] The advantages of this solution are at least that: when maintaining the pressure of the product, the product is first lifted from the conveyor belt by the lifting mechanism, and then fixed by the positioning mechanism. When fixing, the driving assembly drives the mounting plate and the buffer mechanism on the mounting plate to move, so as to position the product. When the buffer mechanism contacts the product, the impact force of the product is reduced under the action of the buffer mechanism, thereby avoiding the situation in the prior art where the product is damaged due to excessive impact force when positioning the product.

[0009] The utility model is further configured as follows: the buffer mechanism includes a base plate installed on a mounting plate, a guide rail is provided on a side wall of the base plate, a first slider and a second slider are slidably installed in the guide rail, a first buffer rod and a second buffer rod are respectively provided on the first slider and the second slider, the first buffer rod and the second buffer rod are rotatably connected to each other, a positioning plate is installed at one end of the first buffer rod and the second buffer rod away from the mounting plate, the first buffer rod and the second buffer rod are rotatably connected to the positioning plate, a protective sleeve is mounted on the outer wall of the positioning plate, and a buffer assembly is installed between the side walls of the first slider and the second slider and the inner wall of the guide rail.

[0010] The utility model is further configured as follows: the buffer assembly is a plurality of first buffer springs.

[0011] The utility model is further configured as follows: through holes are symmetrically opened on the first slider and the second slider, a stabilizing rod is installed on the inner side wall of the guide rail, and the first slider and the second slider are slidably installed on the stabilizing rod through the through holes.

[0012] The utility model is further configured as follows: a limiting block for preventing the first sliding block and the second sliding block from sliding off the stabilizing bar is provided at one end of the stabilizing bar away from the inner side wall of the guide rail.

[0013] The utility model is further configured as follows: a buffer seat is symmetrically installed on the side wall of the bottom plate, a buffer block is slidably installed in the buffer seat, a second buffer spring is provided between the side wall of the buffer block and the inner wall of the buffer seat, a buffer sheet is pasted on the side wall of the buffer seat, and the buffer block is fixedly connected to the positioning plate.

[0014] The utility model is further configured as follows: the protective sleeve and the buffer sheet are both made of silica gel.

[0015] The utility model is further configured as follows: the side wall of the protective sleeve is provided with anti-slip patterns.

[0016] In summary, the utility model has at least the following advantages:

[0017] 1. By setting a buffer mechanism, when the product is pressure-maintained, the product is first lifted from the conveyor belt by the lifting mechanism, and then fixed by the positioning mechanism. When fixed, the driving component drives the mounting plate and the buffer mechanism on the mounting plate to move, so as to position the product. When the buffer mechanism contacts the product, the impact force of the product is reduced under the action of the buffer mechanism, thereby avoiding the situation in the prior art where the product is damaged due to excessive impact force when the product is positioned;

[0018] 2. By setting a buffer assembly, when the first slider and the second slider move in the guide rail, the first buffer spring can absorb the impact force from the positioning plate on the product. By setting a stabilizing bar, the first slider and the second slider can move more stably, and the limit block on the stabilizing bar can prevent the first slider and the second slider from sliding off the stabilizing bar when they move on the stabilizing bar.

[0019] 3. By setting the buffer seat, the buffer block and the second buffer spring, when positioning the product, it plays a role of re-buffering to a certain extent, and also plays a guiding role. The buffer sheet prevents the direct collision between the positioning plate and the buffer seat. The protective cover mounted on the outer wall of the positioning plate prevents the positioning plate from directly contacting the product and reduces damage to the product. The anti-slip texture on the side wall of the protective cover prevents slipping when positioning the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 3 , Figure 4 , Figure 5 As shown (refer to Figure 7 ), the buffer mechanism 10 includes a bottom plate 1001 mounted on the mounting plate 9, a guide rail 1002 is provided on the side wall of the bottom plate 1001, a first slider 1003 and a second slider 1004 are slidably mounted in the guide rail 1002, a first buffer rod 1005 and a second buffer rod 1006 are respectively provided on the first slider 1003 and the second slider 1004, the first buffer rod 1005 and the second buffer rod 1006 are rotatably connected, and a positioning plate 1007 is installed at one end of the first buffer rod 1005 and the second buffer rod 1006 away from the mounting plate 9;

[0031] The first buffer rod 1005 and the second buffer rod 1006 are rotatably connected to the positioning plate 1007. A protective sleeve 1008 is sleeved on the outer wall of the positioning plate 1007. The protective sleeve 1008 is made of silicone. The function of the protective sleeve 1008 is to prevent the positioning plate 1007 from directly contacting the product and reduce damage to the product. The side wall of the protective sleeve 1008 is provided with anti-skid patterns. The function of the anti-skid patterns is to prevent the product from slipping when positioning.

[0032] A buffer component 1009 is installed between the side walls of the first slider 1003 and the second slider 1004 and the inner wall of the guide rail 1002. The buffer component 1009 is a plurality of first buffer springs. The function of the buffer component 1009 is as follows: when the first slider 1003 and the second slider 1004 move in the guide rail 1002, under the action of the first buffer springs, it can not only absorb the impact force from the positioning plate 1007 on the product, but also avoid the first slider 1003 and the second slider 1004 from directly colliding with the inner wall of the guide rail 1002, thereby increasing the service life of the base plate 1001.

[0033] like Figure 5 , Figure 6 As shown, through holes 11 are symmetrically provided on the first slider 1003 and the second slider 1004, and a stabilizing bar 12 is installed on the inner side wall of the guide rail 1002.

The buffer sheet 17 is made of silicone. The buffer block 15 is fixedly connected to the positioning plate 1007. When positioning the product, under the action of the buffer seat 14, the buffer block 15 and the second buffer spring 16, it plays a role of re-buffering to a certain extent, and also plays a role of guiding. The buffer sheet 17 prevents the positioning plate 1007 and the buffer seat 14 from directly colliding.

[0035] The working process and beneficial effects of the utility model are as follows:

[0036] When the product is pressurized, the product is first lifted from the conveyor belt 1 by the lifting mechanism 5, and then fixed by the positioning mechanism 4. When fixed, the driving component 8 drives the mounting plate 9 and the buffer mechanism 10 on the mounting plate 9 to move, so as to position the product. When the positioning plate 1007 on the buffer mechanism 10 contacts the product, the first buffer rod 1005 and the second buffer rod 1006 drive the first slider 1003 and the second slider 1004 to move in the guide rail 1002 and on the stabilizing rod 12. When moving, the first slider 1003 and the second slider 1004 will simultaneously compress the buffer assembly 1009 to absorb a certain impact force, thereby reducing the direct impact force of the positioning plate 1007 on the product, and avoiding the situation in the prior art where the product is damaged due to excessive impact force when the product is positioned.
