[0033] In summary, the technical effects and advantages of the present application are:

[0034] 1. The cold-rolled steel frame of this screen with a protective mechanism uses a softer colloid to absorb the vibration force when the frame body is subjected to minor impacts and vibrations. The vibration force is not easily transmitted to the inside of the frame body, thus protecting the electronic components inside the frame body from damage. When the frame body is subjected to a larger impact, a harder buffer strip and a softer colloid are used together to absorb the vibration force, which can absorb a larger impact force. At the same time, when the frame body deforms, the deformed frame body squeezes the buffer strip and colloid, preventing it from directly squeezing the internal LCD panel, thereby protecting the LCD panel and components inside the frame body from direct damage from large impacts and squeezing.

[0035] 2. In this invention, the front and rear dual workstations with convertible positions allow the outer frame body to perform the buffer strip laying process after the adhesive is applied. By changing positions, the outer frame body can be glued and buffer strips laid again. The process of multiple glue application and buffer strip laying cycles can be met using only two workstations, saving workstations and equipment, improving the space utilization rate of the factory, saving initial investment costs, reducing the need for handling the outer frame body, making the outer frame body less susceptible to damage from impacts during handling, and improving the yield rate.

[0036] 3. In this invention, the processing method closely coordinated with the processing device, through the process of repeatedly applying glue and laying buffer strips in a cycle, allows the other station to lay buffer strips while one station is applying glue, ensuring the continuous and sequential progress of the process and improving processing efficiency.

[0037] 4. In this invention, when it is necessary to cut the buffer strip, the electric push rod pushes the cutter downward to the position of the buffer strip. The cutter drives the contact block to move, the contact block abuts against the inclined block, and under the action of the inclined surface of the inclined block, pushes the cutter to move. The cutter abuts against the buffer strip and forms a shearing force with the outer frame body to cut the buffer strip. The buffer strip can be cut after it is pasted, which eliminates manual operation, saves time and effort, saves processing time, improves processing efficiency, and ensures continuous processing.

DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0056] Embodiment: Reference Figure 1 The screen outer frame cold-rolled plate with a protection mechanism shown in the figure comprises an outer frame body, and the outer frame body is provided with a protection mechanism 2;

[0057] The protection mechanism 2 comprises buffer strips 21 and glue 22, the glue 22 is arranged between the two buffer strips 21, when the outer frame body is slightly extruded, the outer frame body extrudes the buffer strips 21, the glue 22 between the two buffer strips 21 is deformed and provides a buffer force when being extruded, and the buffer strips 21 are deformed and provide a buffer force when contacting each other.

[0058] In the use of the screen outer frame cold-rolled plate with the protection mechanism, when the outer frame body is slightly shaken and impacted, the colloid 22 between the two buffer strips 21 is extruded, the material of the colloid 22 is relatively soft, the colloid 22 is deformed to absorb the shock force, when the outer frame body is impacted by a larger impact, the colloid 22 is deformed to the point that the two buffer strips 21 are in contact, the buffer strips 21 are extruded and deformed, the material of the buffer strips 21 is relatively hard and has better elasticity, and the buffer strips 21 can absorb a larger impact force.

[0059] When the outer frame body is impacted by a smaller impact and shaken, the softer colloid 22 is used to absorb the shock force, and the shock force is not easily transmitted to the inside of the outer frame body, thereby protecting the electronic components inside the outer frame body from being damaged by the shaking, when the outer frame body is impacted by a larger impact, the harder buffer strips 21 and the softer colloid 22 are used to jointly absorb the shock force, and the buffer strips 21 and the colloid 22 can absorb a larger impact force, and when the outer frame body is deformed, the deformed outer frame body extrudes the buffer strips 21 and the colloid 22, and does not directly extrude the inner liquid crystal panel, thereby protecting the liquid crystal panel and the parts inside the outer frame body from being directly damaged by a larger impact and extrusion.

[0060] Further, the outer frame body is composed of a steel alloy with the following composition in terms of weight %: C 0.4-0.8, Si 0.4-1.2, Mn 0.2-0.55, Cr 3.5-4.5, W 1.5-4.0, and Mo 1.0-1.8, with the balance being Fe and the usual impurities.

[0062] When the buffer strip 21 is extruded, the buffer protrusion 212 enters the buffer cavity 211 on the other buffer strip 21 and extrudes the colloid 22 in the buffer cavity 211, the colloid 22 is deformed to absorb the shock force, when the impact force or the shock force cannot be completely absorbed by the colloid 22, the buffer strip 21 continues to be extruded, the buffer protrusion 212 completely enters the buffer cavity 211 on the other buffer strip 21, the two buffer strips 21 are in contact and are extruded and deformed, and a larger shock force is absorbed.

[0063] The colloid 22 is arranged in the buffer cavity 211, and the buffer protrusion 212 cooperates with the buffer cavity 211, so that the colloid 22 is not easily extruded and separated, and the two buffer strips 21 are not easily misaligned when extruded, thereby improving the ability to absorb the impact force.

[0064] Further, referring to Figures 2-3 , the protection mechanism 2 is pasted on the inside of the outer frame body through the colloid 22.

[0065] The protective mechanism 2 is not easy to be separated from the outer frame body, the glue body 22 has buffering capacity, and the protection capacity of the outer frame body is further increased.

[0066] Further, the material of the buffer strip 21 is rubber material, so that the elasticity of the buffer strip 21 is higher, the impact absorbing capacity is stronger, and the service life is high.

[0067] Further, the material of the glue body 22 is polyurethane adhesive, so that the glue body 22 is softer, can absorb dense and small vibration force, and the vibration resistance of the outer frame body is stronger.

[0094] When the first machining table 4 moves, the belt 152 above the connecting wheel 151 moves, the belt 152 moves in a ring shape through the connecting wheel 151, the belt 152 below the connecting wheel 151 drives the fixed frame 9 to move in the opposite direction of the first machining table 4, and the moving amount is the same as that of the first machining table 4, when the first machining table 4 moves, the fixed frame 9 and the second machining table 5 can be driven to move in the opposite direction with the same moving amount.

[0095] Further, referring to Figure 4 The two sides of the top of the support frame 3 are fixedly provided with first guide rails 25, and the bottom of the first processing table 4 is fixedly provided with first sliding blocks 26 which are slidingly matched with the first guide rails 25, thereby supporting the first processing table 4 and enabling the first processing table 4 to move horizontally and stably.

[0096] Further, referring to Figure 4 The bottom of the support frame 3 is fixedly provided with two second guide rails 27, and the bottom of the fixed frame 9 is fixedly provided with two second sliding blocks 28 which are slidingly matched with the second guide rails 27, thereby supporting the fixed frame 9 and enabling the fixed frame 9 to move horizontally and stably.

[0097] Further, referring to Figure 6 The bottom of the second processing table 5 is fixedly provided with a connecting rod 16, and the support frame 3 is fixedly provided with a connecting plate 17 on which a path groove 7 is formed. The rolling wheel 6 is rotatably connected to one side of the connecting rod 16 close to the connecting plate 17 and is arranged in the path groove 7. The bottom of the second processing table 5 is fixedly provided with sliding rods 19 at four corners, and the fixed frame 9 is provided with sliding holes corresponding to the positions of the second processing table 5. The sliding rods 19 pass through the corresponding sliding holes and are slidingly matched with the sliding holes.

[0098] When the fixed frame 9 moves, the second processing table 5 moves horizontally through the sliding rods 19, the connecting rod 16 moves through the second processing table 5, and the rolling wheel 6 moves through the connecting rod 16. The rolling wheel 6 moves in the path groove 7 and drives the second processing table 5 to move along the path groove 7.

[0099] Further, referring to Figure 4 and Figure 7 The path groove 7 comprises an arc-shaped section 71 and two horizontal sections 72, the two ends of the arc-shaped section 71 are communicated with the corresponding horizontal sections 72, and the arc-shaped section 71 is arranged in an arc shape with the middle being low and the two ends being high.

[0100] When the scroll wheel 6 is located in the horizontal section 72 and does not move, the tendency of the second processing table 5 to move in the vertical direction is limited, the tendency of the first processing table 4 and the second processing table 5 to move in the horizontal direction is limited by the driving assembly 14 and the linkage assembly 15, the first processing table 4 and the second processing table 5 are fixed, more stable during processing, and not easy to shake. The specific limiting way of the tendency of the first processing table 4 and the second processing table 5 to move in the horizontal direction is that when the ball screw 142 does not rotate, the moving block 143 is self-locked with the ball screw 142, the self-locking is a screw and nut self-locking, which is a prior art and a conventional means. The moving block 143 is self-locked and cannot move, so that the first processing table 4 cannot move horizontally. The belt 152 is fixed on the first processing table 4, the belt 152 cannot move, so that the fixed frame 9 fixed on the belt 152 cannot move horizontally, and the second processing table 5 cannot move horizontally.

The contact block 206 is fixedly installed on one side of the cutter 204 close to the support plate 201. The electric push rod 202 pushes the cutter 204 and the contact block 206 to move. The contact block 206 contacts the inclined block 205, and pushes the cutter 204 to cut the buffer strip 21.

[0102] When it is necessary to cut the buffer strip 21, the electric push rod 202 pushes the cutter 204 to move downward to the position of the buffer strip 21. The cutter 204 drives the contact block 206 to move. The contact block 206 abuts against the inclined block 205 and pushes the cutter 204 to move under the action of the inclined surface of the inclined block 205. The cutter 204 abuts against the buffer strip 21 and forms a shearing force with the outer frame body to cut the buffer strip 21.

[0103] The buffer strip 21 can be cut after being pasted, which saves manual operation, saves time and effort, saves processing time, improves processing efficiency, and ensures continuous processing.

[0104] Further, with reference to Figure 1 and Figure 10The outer frame body is provided with a connecting groove 31 corresponding to the position of the cutter 204, and the moving plate 203 is fixedly provided with a cutter blade 32.

[0105] Further, referring to Figure 10 , the cutter 204 and the cutter blade 32 are fixedly provided with a clamping piece 33 on one side. When the cutter 204 and the cutter blade 32 cut the buffer strip 21, the two clamping pieces 33 clamp the buffer strip 21 to prevent the buffer strip 21 from being separated from the compression wheel 112.

[0106] Further, referring to Figure 11 and Figure 12 , the moving plate 203 is provided with a moving groove 34, and the cutter 204 is fixedly provided with a connecting block 35 on the end close to the moving plate 203. The connecting block 35 is slidingly connected in the moving groove 34, and the connecting block 35 is fixedly provided with a compression spring 36 on the side away from the support plate 201. The other end of the compression spring 36 is fixedly installed on the corresponding groove wall of the moving groove 34, so that the cutter 204 can be reset when not shearing the buffer strip 21.

[0107] Further, referring to Figure 11 and Figure 12 , the moving groove 34 is fixedly provided with a guide rod 43, and the compression spring 36 is sleeved on the guide rod 43. The connecting block 35 is slidingly matched on the guide rod 43 through a guide hole, so that the compression spring 36 is not easy to bend to the side when being compressed, and the connecting block 35 is limited in the moving groove 34.

[0108] Further, referring to Figure 9 , the connecting piece 12 is further fixedly connected with a fixed plate 37, and the fixed plate 37 is provided with a fixed hole 38.
