Description

Technical Field

[0001] The utility model relates to the technical field of support plate production, in particular to a support plate production device. Background Art

[0002] Smartphones are a very common communication tool in modern society, and their components are very complex. The display screen, as the main image output component, needs to be installed on the phone through a support plate, which is punched out from the material strip. Figure 1 As shown, the material strip is divided into three layers from top to bottom, the first layer is a 0.075mm top film, the second layer is a 0.02mm pressure-sensitive adhesive, and the third layer is a 0.05mm stainless steel. During the processing, the processing component needs to punch the material strip upward to form a support plate. After the support plate is separated from the material strip, the processing component pushes the support plate back 0.08mm to make the support plate abut against the material strip, so that the support plate can be pushed out of the processing component under the push of the material strip.

[0003] However, because the punching surface of the support plate is very sharp, and the top film and pressure-sensitive adhesive in the material strip are relatively fragile, when the support plate is pushed back from top to bottom, the stainless steel layer of the support plate first contacts the top film and pressure-sensitive adhesive in the material strip, and the sharp stainless steel layer can easily scratch the side of the material strip, thus affecting the production quality of the support plate.

[0004] Therefore, how to design a device to improve the production quality of the support plate is a problem that those skilled in the art need to solve. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a support plate production device, aiming to solve the problem of scratching the material strip during the process of pushing the support plate back from top to bottom.

[0014] In one embodiment, along the transmission direction of the material belt, at least one set of the guide components is located in front of the cutter.

[0015] In one embodiment, a guide column is fixedly mounted on the surface of the first mold base facing the second mold base, and a docking hole corresponding to the guide column is opened on the surface of the second mold base facing the first mold base. When the first mold base moves toward the second mold base, the first mold base drives the guide column to be inserted into the docking hole, thereby ensuring the accuracy of the relative position between the first mold base and the second mold base.

[0031] Please refer to Figure 2 and Figure 3 , which shows a support plate production device provided in an embodiment of the utility model, which is used to cut out a support plate 4 from a material strip 5, comprising:

[0032] A conveying assembly 1, used for conveying a material belt 5;

[0033] A processing assembly 2, the processing assembly 2 is used to cut out a support plate 4 and a handle 6 from a material strip 5, and the support plate 4 is connected to the material strip 5 through the handle 6;

[0034] The cutting assembly 3 is located in front of the processing assembly 2 along the conveying direction of the material belt 5. The conveying assembly 1 drives the material belt 5 to pass through the cutting assembly 3. The cutting assembly 3 is used to cut off the connection between the handle 6 and the material belt 5.

[0035] like Figure 1 As shown, the material belt 5 is laid flat on the conveyor assembly 1 and moves under the drive of the conveyor assembly 1. The conveyor assembly 1 includes a frame and a conveyor belt. The frame is installed on the ground and is used to receive the transmission belt and the material belt. Preferably, there are two conveyor belts, which are arranged on the frame at intervals along the width direction of the material belt, and the spacing between the two conveyor belts is slightly smaller than the width of the material belt. At the same time, the frame corresponds to the conveyor belt and is also arranged at intervals along the width direction of the material belt.

[0036] When the conveying component 1 drives the material belt 5 to pass through the processing component 2, the processing component 2 needs to lift the material belt 5 upward from the bottom and perform punching processing. Because the frame and the conveyor belt are arranged at intervals along the width direction of the material belt 5, there will be no interference with the movement of the processing component 2. In the present application, the processing component 2 does not completely cut off the processed support plate 4 and the material belt 5 during the processing. Instead, a handle 6 is cut out, and the support plate 4 and the material belt 5 are connected by the handle 6. After the processing component 2 completes the processing, it is only necessary to push the support plate 4 back down 0.02mm to ensure that the support plate 4 is smoothly transmitted, and the power of the material belt 5 is transmitted through the handle 6. The material belt 5 drives the handle 6 to move, and the handle 6 drives the support plate 4 to move out of the processing component 2.

[0037] Finally, because the cutting assembly 3 is arranged in front of the processing assembly 2, when the handle 6 drives the support plate 4 to move out of the processing assembly 2, it enters the cutting assembly 3. The cutting assembly 3 cuts off the handle 6, so that the support plate 4 and the material belt 5 are separated.

[0038] Preferably, when processing the handle 6, the processing component 2 performs a rounding process on the connection between the handle 6 and the material strip 5. When the cutting component 3 cuts the handle 6, the cutting position is selected from the position where the rounding process is performed, so that the punching surface formed by the punching of the processing component 2 and the punching surface formed by the cutting component 3 are transitioned through an arc, making the connection smoother.

[0039] Therefore, in the present application, after the processing is completed, the processing assembly 2 does not need to push the support plate 4 back down by 0.08 mm, and transmit the power through the contact between the material strip 5 and the support plate 4. Instead, the power of the material strip 5 is transmitted through the handle 6, which greatly reduces the push-back depth of the support plate 4, thereby reducing the scratches on the material strip 5 caused by the sharp punching surface of the support plate 4, and improving the production quality of the support plate 4.

[0040] In one embodiment, the cutting assembly 3 includes a first die holder 31 and a second die holder 32 arranged opposite to each other, and the first die holder 31 and the second die holder 32 can move toward each other to cut off the connection between the handle 6 and the material belt 5;

[0041] A cutter 33 is fixedly mounted on the surface of the first die base 31 facing the second die base 32 . A cutter opening 34 is formed on the surface of the second die base 32 facing the first die base 31 . The first die base 31 drives the cutter 33 to move toward the second die base 32 , so that the cutter 33 is inserted into the cutter opening 34 .

[0042] Please refer to Figure 3, wherein the first die base 31 is at the top, the second die base 32 is at the bottom, and the material belt 5 drives the support plate 4 and the handle 6 to pass between the first die base 31 and the second die base 32. The surface of the first die base 31 facing the second die base 32 is the lower surface of the first die base 31, and the cutter 33 is installed on the lower surface of the first die base 31. The surface of the second die base 32 facing the first die base 31 is the upper surface of the second die base 32, and a knife edge 34 is provided on the upper surface of the second die base 32 at a position corresponding to the cutter 33. And along the conveying direction of the conveying assembly 1, the cutter 33 and the handle 6 are in the same line.

[0043] Therefore, when the material belt 5 drives the handle 6 to move to the bottom of the cutter 33, the cutter 33 is facing the connection between the handle 6 and the material belt. At this time, the first die base 31 is activated, and the first die base 31 drives the cutter 33 to move toward the second die base 32, so that the cutter 33 is smoothly inserted into the cutting edge 34. The cutter 33 cuts off the connection between the handle 6 and the material belt 5, so that the support plate 4 can be completely separated from the material belt 5, and then enter the next process. In this embodiment, the connection between the handle 6 and the material belt 5 can be quickly and accurately cut off by the cutter 33.

[0044] In one embodiment, the cutting assembly 3 further includes a plurality of guide assemblies, which are fixedly mounted on the surface of the first die base 31 facing the second die base 32, and each guide assembly includes two guide members 35, which are arranged on both sides of the width direction of the material strip 5 to guide the transmission direction of the material strip 5. In one embodiment, the guide member 35 is cylindrical, and its end facing the second die base 32 is conical. In one embodiment, along the transmission direction of the material strip 5, at least one guide assembly is located in front of the cutter 33.

[0045] Please refer to Figure 3 and Figure 4 In this embodiment, two sets of guide assemblies are used. The first set of guide assemblies is located in front of the first die base 31, that is, at the entrance of the material strip 5 entering the cutting assembly 3, and the second set of guide assemblies is arranged adjacent to the cutter 33 and located in front of the cutter 33. The first set of guide assemblies can guide the material strip 5 at the entrance, and the second set of guide assemblies can again ensure that the transmission direction of the material strip 5 to be cut is correct, ensuring that the cutter 33 cuts accurately. Because the guide assemblies are fixedly installed on the lower surface of the first die base 31, the guide assemblies move with the first die base 31.

[0046] When the first die base 31 moves toward the second die base 32, the guide assembly is driven to move downward together. The length of each guide member 35 is greater than the length of the cutter 33, so as to ensure that when the first die base 31 moves toward the second die base 32, the guide member 35 is first driven to guide the material strip 5, and then the cutter 33 cuts the material strip 5. The spacing between the two guide members 35 in the same group corresponds to the width of the material strip 5, and the gap between each guide member 35 and the edge of the same side of the material strip 5 is 0.01mm, so as to ensure that the transmission direction of the material strip 5 does not deviate after the material strip 5 passes through the limit of the two guide members 35 in the same group.

[0047] like Figure 3 As shown, preferably, the lower end of the guide member 35 is tapered. When the material strip 5 is partially offset, the first mold base 31 drives the guide member 35 to move toward the material strip 5 until the lower end of the guide member 35 abuts against the offset portion of the material strip 5. At this time, the offset portion of the material strip 5 will move along the oblique edge of the guide member 35 and return to the correct transmission direction under the abutment of the guide member 35. In this embodiment, the material strip 5 is guided by the tapered end of the guide member 35, which can reduce damage to the material strip 5.

[0048] In one embodiment, a guide post 36 is fixedly mounted on the surface of the first mold base 31 facing the second mold base 32, and a docking hole corresponding to the guide post 36 is opened on the surface of the second mold base 32 facing the first mold base 31. When the first mold base 31 moves toward the second mold base 32, the first mold base 31 drives the guide post 36 to be inserted into the docking hole, thereby ensuring the accuracy of the relative position of the first mold base 31 and the second mold base 32.

[0049] Please refer to Figure 3 , the guide post 36 is also installed on the lower surface of the first die base 31, and the length of the guide post 36 is also greater than the length of the cutter 33. When the first die base 31 moves toward the second die base 32, it drives the guide post 36 to move downward together. Because the guide post 36 is longer than the cutter 33, the guide post 36 preferably abuts the second die base 32. A docking hole is provided at the position corresponding to the guide post 36 on the second die base 32, so that the guide post 36 can be inserted. If the relative position of the first die base 31 and the second die base 32 is accurate, the guide post 36 can be smoothly inserted into the docking hole, so that the first die base 31 drives the cutter 33 to be inserted into the cutter connection 34. If the relative position of the first die base 31 and the second die base 32 is inaccurate, the guide post 36 cannot be inserted into the docking hole, and the guide post 36 preferably abuts against the second die base 32. At this time, even if the cutter 33 is not aligned with the cutter connection 34, the cutter 33 will not continue to move toward the second die base 32, and the cutter 33 will not abut against the second die base 32. In this embodiment, the guide pillars 36 ensure that the relative positions of the first die holder 31 and the second die holder 32 are accurate, thereby protecting the cutter 33 from collision damage due to inaccurate position.

[0050] In one embodiment, the cutter 33 is an oblique side edge cutter. In one embodiment, the cutter 33 is detachably connected to the first die holder 31. Figure 3 As shown, the cutting edge of the cutter 33 is inclined to one side, and is an oblique side-edge cutter. In this embodiment, the cutter 33 adopts an oblique side-edge cutter, which can make the force on the material strip 5 more accurate when the cutter 33 is cutting. At the same time, even if the blade of the oblique side-edge cutter is worn or damaged, it can be polished by the bevel, so that the cutter 33 can be reused, thereby increasing the service life of the cutter 33. The cutter 33 is detachably connected to the first mold base 31, which can realize the rapid replacement of the cutter 33, thereby improving work efficiency.

[0051] In one embodiment, a pressing block 37 is installed on the surface of the first die base 31 facing the second die base 32. When the first die base 31 moves toward the second die base 32, the first die base 31 drives the pressing block 37 to press the material strip 5 onto the second die base 32. In one embodiment, the cutting assembly 3 further includes an elastic member 38, and the pressing block 37 is elastically connected to the first die base 31 through the elastic member 38.

[0052] Please refer to Figure 3 A pressing block 37 is also installed on the first die base 31. When the first die base 31 moves toward the second die base 32, the pressing block 37 is driven to move downward together, so that the pressing block 37 abuts against the support plate 4, thereby pressing the material strip 5 and the support plate 4 together on the second die base 32 to ensure stability during cutting.

[0053] In this embodiment, an elastic member 38 is also used for connection, and the elastic member 38 is preferably a spring. After the pressing block 37 is installed on the lower surface of the first die base 31 through the elastic member 38, when the elastic member 38 is relaxed, the pressing block 37 is closer to the second die base 32 than the cutter 33. Therefore, when the first die base 31 moves toward the second die base 32, the pressing block 37 preferably presses the support plate 4 against the second die base 32 to ensure that the material strip 5 and the support plate 4 will not be offset due to external interference before cutting. At this time, due to the presence of the elastic member 38, the first die base 31 can still continue to move toward the second die base 32, and the first die base 31 compresses the elastic member 38, and at the same time, the first die base 31 drives the cutter 33 to complete the cutting.

[0054] When the first die base 31 moves away from the second die base 32, the cutter 33 leaves the material strip 5 first, and at this time, the pressing block 37, under the action of the elastic member 38, still presses against the support plate 4 to ensure that the handle 6 does not affect the cutter 33. When there is a certain distance between the cutter 33 and the material strip 5, the pressing block 37 stops pressing the support plate 4.

[0055] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
