Description
Technical Field
[0001] The invention relates to the field of general equipment, and in particular to a diaphragm bending device with dual functions of flattening and bending. Background Art
[0002] Currently, the diaphragm materials in the display industry on the market are generally cut by two methods: flat knife punching device or circular knife cutting device. During the cutting process, the diaphragm material will bend and deform at the edge due to the extrusion of the knife. When using a flat knife punching device for impact cutting, the edge of the diaphragm material will bend downward, and when using a circular knife cutting device for cutting, the edge of the diaphragm material will bend due to external factors such as the cutting speed and the sharpness of the circular cutter. Since most of the diaphragm materials in the display industry are composite structures with certain plasticity, when the edge of the diaphragm material is bent, it cannot be restored to straightness under the action of its own elasticity. This requires the use of additional folding equipment to fold the edge of the diaphragm material flat. Secondly, in different usage scenarios, in order to improve the practicality of the diaphragm material, enhance the structural strength or improve the appearance and function, the diaphragm material needs to be technically bent. This technical bending is different from the bending caused by the edge during cutting. When the diaphragm material is technically bent, additional bending equipment is required to achieve it.

[0020] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0021] like Figure 1 to Figure 6 As shown, the diaphragm bending device with dual functions of folding and bending described in the present invention includes a base 1, a bending mechanism 2 and a roller conveyor 3 are respectively arranged on the left and right sides of the base 1, a base 21 in the bending mechanism 2 is fixed on the base 1, a slide 22 is slidably arranged in the base 21, a connecting seat 11 is arranged on the base 1, a lead screw 12 is rotatably arranged between the base 21 and the connecting seat 11, two guide rods 13 are arranged in parallel on both sides of the lead screw 12, the slide 22 is threadedly connected to the lead screw 12, the slide 22 is slidably connected to the two guide rods 13, one end of the lead screw 12 extends out of the base 21, and a rotating wheel handle 121 is arranged on the lead screw 12 extending out of the base 21.
[0022] A workbench 23 is arranged on the slide 22, and the workbench 23 is connected to the slide 22 by countersunk bolts. The countersunk bolts are immersed in the workbench 23 and will not affect the flatness of the top surface of the workbench 23. A plane support block 4 is arranged on the right side of the workbench 23 close to the roller conveyor 3. The plane support block 4 and the workbench 23 are also connected by countersunk bolts. The top surface of the plane support block 4 is flush with the conveying surface of the roller conveyor 3. Baffles 24 are vertically arranged on the front and rear side walls of the workbench 23, and a limiting groove 241 is arranged on the inner side wall of the baffle 24. A top stopper 242 extending toward the workbench 23 is arranged on the top wall of the baffle 24. A bracket 5 is arranged on the workbench 23 for sliding left and right. The top wall of the seat 5 slides against the top stopper 242 of the two baffles 24, and the front and rear side walls of the bracket 5 slide against the inner side walls of the two baffles 24 respectively. Limiting blocks 51 are protrudingly provided on the front and rear outer side walls of the bracket 5. An arc groove 52 is provided on the right side wall of the bracket 5. The arc groove 52 extends along the circumference of the right side wall, and its radial depth direction extends to the bottom wall of the bracket 5, so that there is no solid material gap between the arc groove 52 and the bottom wall of the bracket 5. When the bracket 5 moves to the right to completely cover the plane bracket 4, since there is no solid material gap between the arc groove 52 and the bottom wall of the bracket 5, the arc groove 52 can actually be regarded as extending to the top surface of the plane bracket 4, so that the bracket 5 covers the plane bracket 4. When the flat support block 4 is moved, the lowest surface of the support seat 5 is also flush with the conveying surface of the roller conveyor 3. A double-axis reduction motor 231 is arranged on the left side wall of the workbench 23 away from the roller conveyor 3. Two rotating shafts 232 are coaxially rotated between the double-axis reduction motor 231 and the two baffles 24. Gears 233 are fixedly arranged on the two rotating shafts 232. A rack plate 53 is clamped on the bottom wall of the support seat 5. The teeth on the rack plate 53 are meshed with the teeth of the two gears 233. The rack plate 53 extends to the left from the support seat 5. When the support seat 5 moves to the left away from the flat support block 4, the rack plate 53 abuts against the base 21 to play a limiting role. When the support seat 5 moves to the right to completely cover the flat support block 4, the limit block 51 on the support seat 5 abuts against the same side The groove wall of the limiting groove 241 plays a front limiting role for the rack 53 and the bracket 5, two limiting holes 531 are symmetrically arranged on the front and rear sides of the bottom wall of the rack plate 53, and two limiting cylinders 234 are symmetrically arranged on the front and rear sides of the left side wall of the workbench 23. Limiting plates are arranged on the piston rods of the two limiting cylinders 234. When the bracket 5 moves to the right to completely cover the flat support block 4, the two limiting holes 531 on the rack plate 53 are respectively aligned with the limiting plates in the two limiting cylinders 234. The limiting cylinder 234 drives the limiting plates to be inserted upward into the corresponding limiting holes 531 to play a rear limiting role for the rack 53 and the bracket 5. The bracket 5 can be fixed on the workbench 23 under the front and rear limiting effects.
[0023] A loop 211 is movably mounted on the base 21, and a first tightening bolt 212 is threadedly connected to the loop 211. The first tightening bolt 212 abuts against the base 21 to fix the loop 211. After the first tightening bolt 212 is loosened, the loop 211 can move up and down on the base 21 to adjust the height position of the loop 211. A cross bar 25 is horizontally arranged on the loop 211, and a sleeve 251 is movably mounted on the cross bar 25. Three second tightening bolts 212 are evenly distributed on the circumference of the sleeve 251. The bolt 252 is threadedly connected with a fastening bolt 253 on the right end wall of the cross bar 25, and a swing arm 26 is rotatably arranged on the fastening bolt 253. The fastening bolt 253 and the right end wall of the cross bar 25 abut against the swing arm 26. A spring bolt 261 is threadedly connected to the swing arm 26. A tension spring 27 is arranged between the swing arm 26 and the sleeve 251 on the cross bar 25. One end of the tension spring 27 is hooked on the spring bolt 261, and the other end of the tension spring 27 is hooked on any second fastening bolt. The tension spring 27 is hooked on any one of the second tightening bolts 252, and then the sleeve 251 is rotated to adjust the position of the second tightening bolt 252 to adjust the tension of the tension spring 27. The three second tightening bolts 252 provided on the sleeve 251 can improve the connection strength between the sleeve 251 and the cross bar 25, and prevent the sleeve 251 from rotating on the cross bar 25 due to the elastic tension of the tension spring 27, thereby affecting the tension of the tension spring 27. A pressure wheel 6 is rotatably provided, and the pressure wheel 6 is connected to an encoder 61, and the encoder 61 is fixed on the swing arm 26. There is a rounded corner R between the circumferential wall and the left end wall of the pressure wheel 6. Under the pulling force of the tension spring 27, the circumferential wall of the pressure wheel 6 rests on the top surface of the plane support block 4. A rubber pad 31 is provided on the left side frame of the roller conveyor 3 close to the bending mechanism 2. The top surface of the rubber pad 31 is flush with the conveying surface of the roller conveyor 3 and the top surface of the plane support block 4. The roller conveyor 3 is a prior art and will not be described here.
[0024] When it is necessary to flatten the diaphragm material with bent edges, loosen the fastening bolts 253, move the swing arm 26 to the right until the pressure wheel 6 is separated from the workbench 23, and then start the dual-axis reduction motor 231 to rotate forward, and drive the bracket 5 to move to the left through the gear transmission between the gear 233 and the rack plate 53 to expose the flat support block 4, tighten the fastening bolts 253 again, and the swing arm 26 will reset the pressure wheel 6, and drive the swing arm 26 to rotate toward the workbench 23 under the tension of the tension spring 27, so that the circumferential wall on the pressure wheel 6 is against the flat support block 4, and the diaphragm material is placed on the roller conveyor 3, and the bent edge is placed on the flat support block 4, and the pressure wheel 6 is against the diaphragm material under the tension of the tension spring 27. Figure 2As shown in the figure, the countersunk bolts connecting the plane support block 4 and the workbench 23 are located at the front and rear ends of the plane support block 4, so the pressure wheel 6 needs to be pressed against the center position of the plane support block 4, so when the circumferential wall on the pressure wheel 6 contacts the top surface of the plane support block 4, the pressure wheel 6 will not contact the countersunk holes on the plane support block 4, so when the pressure wheel 6 cooperates with the plane support block 4 to flatten the diaphragm material, no pressure contact will be applied in the direction of the countersunk holes, and the countersunk holes on the plane support block 4 will not damage the diaphragm material. In order to make the pressure wheel 6 abut against the center position of the plane support block 4, it is necessary to adjust the height of the cross bar 25 to cooperate. If the cross bar 25 is too high, the pressure wheel 6 on the swing arm 26 either cannot contact the plane support block 4, or the tension spring 27 applies insufficient tension to the pressure wheel 6, so that the pressing force between the pressure wheel 6 and the plane support block 4 is insufficient, and the diaphragm material cannot be flattened; if the cross bar 25 is too low, the pressure wheel 6 on the swing arm 26 is easy to abut against one end of the plane support block 4 and contact the countersunk hole, and it will also make the tension spring 27 The spring 27 applies excessive tension to the pressure wheel 6, increasing the clamping force between the pressure wheel 6 and the plane support block 4. Excessive clamping force will damage the membrane material, so it is necessary to adjust the height position of the adjusting cross bar 25. This requires adjusting the pressure wheel 6 according to actual conditions. When adjusting, it is only necessary to loosen the first fastening bolt 212 to adjust the loop 211 and the cross bar 25 up and down, thereby adjusting the distance between the pressure wheel 6 and the plane support block 4 to adjust the clamping force between the pressure wheel 6 and the plane support block 4, so as to obtain a suitable clamping force. In order to prevent the pressure wheel 6 and the plane support block 4 from causing wear or tear to the diaphragm material, the pressure wheel 6 and the plane support block 4 are made of the same rubber material, and the diaphragm material contacts the rubber pad 31 on the roller conveyor 3 to prevent the frame on the roller conveyor 3 from tearing the diaphragm material. The diaphragm material will move linearly between the plane support block 4 and the pressure wheel 6 under the conveyance of the roller conveyor 3, thereby driving the movement of the pressure wheel 6. The circumferential wall on the pressure wheel 6 cooperates with the plane support block 4 to flatten the bent edge of the diaphragm material. During the flattening process, the pressure wheel 6 cooperates with the encoder 61 to measure the length of the diaphragm material, thereby obtaining the length of the diaphragm material.
[0025] When it is necessary to perform technical bending on the diaphragm material, loosen the fastening bolts 253, move the swing arm 26 to the right until the pressure wheel 6 is separated from the workbench 23, then start the double-axis reduction motor 231 to reverse, and drive the bracket 5 to move to the right through the gear transmission between the gear 233 and the rack plate 53 until it completely covers the flat bracket 4. The bracket 5 is fixed on the workbench 23 under the front limit and rear limit effects, and tighten the fastening bolts 253 again. The swing arm 26 returns to its original position with the pressure wheel 6, and is driven to rotate toward the workbench 23 under the tension of the tension spring 27, so that the fillet R on the pressure wheel 6 abuts against the arc groove 52 of the bracket 5, as shown in FIG. Figure 1As shown, the second tightening bolt 252 on the sleeve 251 is located on the left side of the swing arm 26, so the tension spring 27 will pull the swing arm 26 to the lower left, so that the rounded corner R of the pressure wheel 6 on the swing arm 26 can always maintain a strong abutment force with the arc groove 52. When it is necessary to adjust the pressure wheel 6 from the state of abutting against the plane support block 4 to the state of the pressure wheel 6 abutting against the arc groove 52 on the support seat 5, the distance between the pressure wheel 6 and the arc groove 52 becomes lower, which increases the clamping force between the pressure wheel 6 and the arc groove 52. In order to prevent the high pressure clamping force from damaging the diaphragm material, it is necessary to increase the distance between the pressure wheel 6 and the arc groove 52 to ensure that the pressure wheel 6 can have a good clamping force with the arc groove 52. It is necessary to loosen the first tightening bolt 212 to move the sleeve 211 and the cross bar 25 upward. At this time, the pressure wheel 6 will rise together, the distance between the pressure wheel 6 and the arc groove 52 will increase, and the clamping force between the pressure wheel 6 and the arc groove 52 will be reduced. Then, the diaphragm material is placed on the roller conveyor 3, and any one side is placed against the arc groove 52 of the bracket 5, and the fillet R on the pressure wheel 6 is against the diaphragm material in the arc groove 52. The diaphragm material will move linearly between the bracket 5 and the pressure wheel 6 under the conveyance of the roller conveyor 3. In order to prevent the pressure wheel 6 and the bracket 5 from causing wear or tear on the diaphragm material, the bracket 5 is made of the same rubber material as the pressure wheel 6. The rotating pressure wheel 6 cooperates with the arc groove 52 of the bracket 5 to prevent the linear motion. The diaphragm material is technologically bent, and the curvature of the technological bending of the diaphragm material is the same as the curvature of the arc groove 52. When the curvature of the technological bending of the diaphragm material needs to be adjusted, it is necessary to replace the bracket 5 with an arc groove 52 with a different curvature. When the width of the technological bending area of the diaphragm material needs to be adjusted, it is achieved by holding the wheel handle 121 and rotating the screw 12, and adjusting the distance between the workbench 23 and the roller conveyor 3 through the threaded transmission action between the slide 22 and the screw 12.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents.
