Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a plate material conveying device with a positioning function. Background Art

[0002] Because ring-pull caps are easy to open without the need for a bottle opener, they are widely used on beverage bottles and cans. The structure of a ring-pull cap consists of a cap body, a sealing gasket, and a plastic ring. In the manufacturing process, sheet material, such as aluminum alloy sheet, is punched and stretched to form the cap body, and a pattern is created on the cap body through printing or coding.

[0003] In actual production work, due to the low precision of aluminum alloy sheet strips, there are slight errors in the width dimensions of different batches of aluminum alloy sheets. What's more, the long side of the aluminum alloy sheet appears S-shaped. These factors will affect the parallelism of the conveying of the aluminum alloy sheet, and easily cause the aluminum alloy sheet to deviate or shift during the conveying process, resulting in inaccurate positioning of the printed pattern or coding pattern on the aluminum alloy sheet, which in turn causes an increase in scrap rate and increased manufacturing costs.

To this end, the present invention proposes a sheet material conveying device with a positioning function, which can convey and accurately position the sheet material, preventing the sheet material from deviating during the conveying process, thereby ensuring the accurate position of the sheet material for the next process.

[0027] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0028] In the description of the present invention, it should be understood that a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] It is understandable that for many products based on sheet materials, printing or coding is required to achieve certain functions or make the product appearance beautiful. In order to print or code in batches quickly, the sheets are often printed or coded one by one during the sheet conveying process.

[0031] However, in actual production, due to the low precision of sheet material stripping, there are slight deviations in the width dimensions of sheets from batch to batch, and some sheets may have an S-shaped long side. These factors will affect the parallelism of sheet material conveyance, which can easily cause the sheet material to deviate or shift during conveyance, adversely affecting printing or coding work.

[0032] Ensuring accurate sheet positioning during sheet conveyance is crucial for the quality of the printing or coding process. If the sheet's conveying position deviates, the printed or coding pattern will deviate from its intended position on the sheet, resulting in incorrect placement of the printed or coding pattern on the sheet. This can lead to substandard printing or coding quality, increased product scrap rates, and increased production costs.

[0033] Based on this, an embodiment of the present invention provides a sheet material conveying device with a positioning function, which can convey the sheet material horizontally and can also accurately position the sheet material, thereby preventing the sheet material from deviating during the conveying process.

[0034] Reference below Figures 1 to 5 The present invention describes a sheet material conveying device with a positioning function provided in an embodiment of the present invention.

[0035] like Figures 1 to 5 As shown, the sheet material conveying device with positioning function according to the embodiment of the utility model has the dual functions of stable horizontal conveying and accurate positioning. It can horizontally convey sheet materials such as aluminum plates and iron plates, and complete the accurate positioning of the sheet materials, effectively preventing the sheet materials from deviating during the horizontal conveying process, thereby providing accurate guarantee of the sheet material position for the next process of the sheet material.

[0036] For example, the sheet material conveying device with a positioning function of this embodiment can be applied to the manufacturing of the cover body of the pull ring cover. It can horizontally convey the aluminum alloy thin plate 500 with a width difference of 1mm to 2mm, and at the same time can complete the accurate positioning of the aluminum alloy thin plate 500, so as to ensure that the position of the sheet material reaches the preset position requirement for the next process such as printing pattern and laser coding process, thereby ensuring the product quality of the next process.

[0037] In this embodiment, the sheet material conveying device with a positioning function has a first direction, a second direction, and an up-down direction, wherein the first direction and the second direction are perpendicular to the up-down direction. To more clearly illustrate the structure of the sheet material conveying device with a positioning function in this embodiment, it is assumed that the first direction is the front-to-back direction, the second direction is the left-to-right direction, the length direction of the sheet material extends along the first direction, and the width direction of the sheet material extends along the second direction.

[0038] like Figures 1 to 5 As shown, the sheet material conveying device with a positioning function includes a conveying mechanism 100 , a first positioning mechanism 400 and an elastic positioning mechanism 300 .

[0039] The conveying mechanism 100 has a conveying plane that can convey the sheet material along a first direction. One end of the conveying plane along the first direction is the feed end, and the other end of the conveying plane along the first direction is the discharge end. The sheet material can move from the feed end to the discharge end. In this embodiment, the conveying mechanism 100 is a belt conveyor. In the conveying mechanism 100, the length of the conveying plane extends along the front-to-back direction, and the width of the conveying plane extends along the left-to-right direction. The conveying plane can convey the sheet material from front to back. Therefore, the front end of the conveying plane is the feed end, and the rear end of the conveying plane is the discharge end. Of course, it is not ruled out that in other embodiments, the conveying mechanism 100 is a chain conveyor or a chain conveyor.

[0040] Specifically, such as Figure 5 As shown, the conveying mechanism 100 includes a frame 110, a conveyor belt 130, a belt roller 120, and a power component. The central axis of the belt roller 120 extends in the left-right direction. The left and right ends of the belt roller 120 are mounted on the frame 110 via bearing blocks. The belt roller 120 can rotate around its own central axis relative to the frame 110. Two belt rollers 120 are provided, one of which is located at the front end of the frame 110 and the other is located at the rear end of the frame 110. The conveyor belt 130 is wound between the two belt rollers 120. Furthermore, a tensioning roller can be added to the conveyor belt 130 to adjust the tension of the conveyor belt 130.

[0041] The function of the power component is to drive one of the belt rollers 120 to rotate, so that the conveyor belt 130 can run and convey the sheet material placed on the conveyor belt 130. The structure of the power component includes a driving wheel 141, a transmission wheel 142, a flexible transmission member 150 and a rotating driving member. The transmission wheel 142 is set at one end of one of the belt rollers 120. The rotating driving member is mounted on the frame 110 by bolts. The rotating driving member may include a motor and a transmission structure. The transmission structure may be a reducer or a coupling. The output end of the rotating driving member is coaxially connected to the driving wheel 141. The flexible transmission member 150 is wound between the driving wheel 141 and the transmission wheel 142. The flexible transmission member 150 may be a chain or a belt. When the rotating driving member is working, the driving wheel 141, the flexible transmission member 150 and the transmission wheel 142 cooperate to drive the belt roller 120 to rotate, and the belt roller 120 drives the conveyor belt 130 to work, thereby realizing horizontal transportation of the sheet material.

[0042] The first positioning mechanism 400 and the elastic positioning mechanism 300 are arranged opposite each other in the second direction. The first positioning mechanism 400 and the elastic positioning mechanism 300 jointly define a positioning area. Moreover, the first positioning mechanism 400 and the elastic positioning mechanism 300 are located between the discharge end and the feed end of the conveying plane. The first positioning mechanism 400 is arranged on one side of the conveying mechanism 100 along the second direction, and the elastic positioning mechanism 300 is arranged on the other side of the conveying mechanism 100 along the second direction. In this embodiment, the first positioning mechanism 400 is arranged on the right side of the conveying mechanism 100, and the elastic positioning mechanism 300 is arranged on the left side of the conveying mechanism 100. Both the first positioning mechanism 400 and the elastic positioning mechanism 300 are mounted on the frame 110. The first positioning mechanism 400 and the elastic positioning mechanism 300 are both arranged near the discharge end of the conveying plane.

[0043] Specifically, the first positioning mechanism 400 includes a guide positioning plate 410, an angle adjustment component 420, and a linear adjustment component 430. The guide positioning plate 410 has a first positioning surface, which is a plane. The length of the first positioning surface extends along the first direction, and the width of the first positioning surface extends along the vertical direction. The first positioning surface is used to guide and position the sheet material. The first positioning surface is located above the conveying plane, that is, there is a certain vertical gap between the first positioning surface and the conveying plane.

[0044] It is understood that the dimensions of the guide positioning plate 410 in the first direction and in the vertical direction can be selected according to actual needs and are not specifically limited here. The length of the guide positioning plate 410 can be designed to be sufficiently large so that the positioning distance of the guide positioning plate 410 is large, allowing the guide positioning plate 410 to stably position the sheet material through the first positioning surface.

[0045] Further, such as Figure 2As shown, the guide positioning plate 410 is provided with a guide chamfer 411, which is located at one end of the guide positioning plate 410 along the first direction. Moreover, the guide chamfer 411 serves to guide the sheet material so that the sheet material can smoothly enter the positioning area and contact the first positioning surface of the guide positioning plate 410. In this embodiment, the guide chamfer 411 is located at the front end of the guide positioning plate 410, that is, the guide chamfer 411 is provided at the end of the guide positioning plate 410 close to the feed end.

[0046] The linear adjustment component 430 is configured to adjust the position of the guide positioning plate 410 in the second direction, and the angle adjustment component 420 is configured to adjust the angular position of the guide positioning plate 410 on the horizontal plane. Figure 2 As shown, the linear adjustment component 430 is a displacement platform, and the angle adjustment component 420 is a rotation platform.

[0047] It is understood that after the guide positioning plate 410 is adjusted according to the requirements of the next process for the position of the sheet material, the first positioning mechanism 400 can cooperate with the elastic positioning mechanism 300 to accurately position each sheet material. When it is necessary to adjust the position of the sheet material in the second direction, the linear adjustment component 430 can be used to adjust the horizontal position of the guide positioning plate 410 along the second direction until the position requirements of the sheet material in the next process are met. If the sheet material is not transported in parallel during the conveying process, the angle adjustment component 420 can be used to adjust the angular position of the guide positioning plate 410 on the horizontal plane, thereby adjusting the sheet material to a parallel conveying state to meet the requirements of the next process for the position of the sheet material.

[0048] The linear adjustment component 430 can be a manual or electric displacement platform, enabling precise adjustment of the horizontal position of the guide positioning plate 410 in the second direction according to the sheet metal positioning requirements. The angle adjustment component 420 can be a manual or electric rotation platform, enabling precise adjustment of the angular position of the guide positioning plate 410 in the horizontal direction according to the sheet metal positioning requirements. Both displacement platforms and rotation platforms are state of the art, and those skilled in the art will understand their specific structures and operating principles, which will not be described in detail here.

[0049] In some examples, the linear adjustment component 430 is arranged on the frame 110 of the conveying mechanism 100, the angle adjustment component 420 is arranged at the output end of the linear adjustment component 430, and the guide positioning plate 410 is arranged at the output end of the angle adjustment component 420. Therefore, through the linear adjustment component 430, the position of the angle adjustment component 420 and the guide positioning plate 410 thereon in the second direction can be fine-tuned with high precision, and through the angle adjustment component 420, the angular position of the guide positioning plate 410 on the horizontal plane can be fine-tuned with high precision.

[0050] In other examples, the angle adjustment component 420 is arranged on the frame 110 of the conveying mechanism 100, the linear adjustment component 430 is arranged at the output end of the angle adjustment component 420, and the guide positioning plate 410 is arranged at the output end of the linear adjustment component 430. Therefore, through the angle adjustment component 420, the angular position of the linear adjustment component 430 and the guide positioning plate 410 thereon on the horizontal plane can be adjusted with high precision, and through the linear adjustment component 430, the position of the guide positioning plate 410 in the second direction can be adjusted with high precision.

[0051] In this embodiment, the linear adjustment component 430 is a manual displacement platform, and the angle adjustment component 420 is a manual rotation platform. Therefore, the operator can manually operate the linear adjustment component 430 or the angle adjustment component 420 according to the actual situation to fine-tune the position of the guide positioning plate 410 with high precision, so that the sheet material can meet the position requirements of the next process under the guidance and positioning of the guide positioning plate 410. The frame 110 is provided with a mounting seat 440, the linear adjustment component 430 is mounted on the mounting seat 440, the angle adjustment component 420 is mounted on the slide of the linear adjustment component 430, and the guide positioning plate 410 is mounted on the rotation platform of the angle adjustment component 420 via a connecting plate.

[0052] The elastic positioning mechanism 300 has a second, elastically floating positioning surface. Furthermore, the elastic positioning mechanism 300 is configured to push the sheet material in the second direction toward the first positioning surface via the second positioning surface. The second positioning surface is located above the conveying plane, i.e., there is a certain vertical gap between the second positioning surface and the conveying plane.

[0053] It is understood that the second positioning surface is capable of elastically expanding and contracting along the second direction, thereby achieving an elastic floating function of the second positioning surface. When the first positioning surface is stationary, when the sheet material enters the positioning area, the second positioning surface elastically floats due to the change in the sheet material's width, causing the sheet material's two side surfaces along the second direction to contact the first positioning surface and the second positioning surface respectively.

[0054] like Figure 1 As shown, there are multiple elastic positioning mechanisms 300, and the multiple elastic positioning mechanisms 300 are arranged in sequence along the first direction of the conveying mechanism 100. In this embodiment, the number of the elastic positioning mechanisms 300 is three. Specifically, as Figure 3 and Figure 4 As shown, the elastic positioning mechanism 300 includes a fixing seat 330 , a spring 340 , a rocker 350 and a positioning wheel 380 .

[0055] The fixed base 330 is bolted to the frame 110 of the conveying mechanism 100. One end of the rocker arm 350 is hingedly connected to the fixed base 330 via a second connecting shaft 390. The second connecting shaft 390 extends in the vertical direction, so the hinge axis of the rocker arm 350 extends in the vertical direction. The positioning wheel 380 is rotatably mounted on the other end of the rocker arm 350. Specifically, the other end of the rocker arm 350 is provided with a first connecting shaft 360. The first connecting shaft 360 extends in the vertical direction. The positioning wheel 380 is mounted on the first connecting shaft 360 via a bearing 370. Therefore, the central axis of the positioning wheel 380 extends in the vertical direction. All the positioning wheels 380 collectively define a second positioning surface, and the outer peripheral surface of the positioning wheel 380 can contact the side surface of the sheet material.

[0056] The spring 340 is arranged between the fixed seat 330 and the rocker arm 350. One end of the spring 340 is connected to the fixed seat 330, and the other end of the spring 340 is connected to the rocker arm 350. The spring 340 can exert an elastic force on the rocker arm 350, and the spring 340 is configured to drive the rocker arm 350 to rotate in a direction close to the first positioning surface.

[0057] It can be understood that in the process of the sheet material entering the positioning area, one side surface of the sheet material will contact the first positioning surface and be guided and positioned, so that the sheet material can move in a straight line along the first positioning surface. At the same time, the other side surface of the sheet material will contact the outer peripheral surface of the positioning wheel 380. At this time, the positioning wheel 380 will be subjected to the pressure exerted by the sheet material, prompting the rocker arm 350 to overcome the elastic force of the spring 340 and drive the positioning wheel 380 to rotate a certain amplitude in the direction away from the first positioning surface, thereby expanding the distance between the positioning wheel 380 and the first positioning surface in the second direction, prompting the sheet material to pass through the positioning area smoothly; moreover, under the elastic force of the spring 340, the outer peripheral surface of the positioning wheel 380 can maintain contact with the side surface of the sheet material, and the positioning wheel 380 will drive the sheet material to maintain contact with the first positioning surface.

[0058] When the sheet material leaves the positioning area, the swing rod 350 drives the positioning wheel 380 under the elastic force of the spring 340 to swing toward the direction close to the first positioning surface.

[0059] As the sheet material moves along the first direction to the positioning area, the outer surface of the positioning wheel 380 contacts the side of the sheet material, creating rolling friction between the sheet material and the positioning wheel 380. This reduces frictional resistance encountered by the sheet material during transport, thereby improving the efficiency of transport and positioning of the sheet material. Furthermore, the positioning wheel 380 is mounted on the rocker 350 and is equipped with a spring 340. This leverage effectively reduces the pressure exerted by the positioning wheel 380 on the sheet material, thereby preventing deformation of the sheet material due to excessive pressure.

[0060] Moreover, if the width of the sheet material changes, the distance between the positioning wheel 380 and the first positioning surface in the second direction will change accordingly. At this time, the deformation of the spring 340 will also change, so that the sheet material can smoothly pass through the positioning area jointly defined by the positioning wheel 380 and the first positioning surface, thereby allowing the sheet material conveying device with positioning function to adapt to the conveying and positioning of sheets of different widths.

[0061] Further, such as Figure 3 and Figure 4 As shown, the elastic positioning mechanism 300 also includes an adjusting bolt 310. The fixing base 330 is provided with a connecting hole, the central axis of which extends along the second direction. The length of the adjusting bolt 310 extends along the second direction. The adjusting bolt 310 is threadedly connected to the connecting hole, securing the adjusting bolt 310 to the fixing base 330. The spring 340 extends and contracts along the second direction. One end of the spring 340 abuts against the end of the adjusting bolt 310 proximal to the rocker arm 350, while the other end of the spring 340 is connected to the rocker arm 350. The connection between the spring 340 and the rocker arm 350 is located between the first connecting shaft 360 and the second connecting shaft 390.

[0062] It should be noted that by setting the adjusting bolt 310, the adjusting bolt 310 can be screwed according to actual usage conditions such as the width of the sheet material to adjust the distance between the rocker arm 350 and the adjusting bolt 310 in the second direction, so that the deformation of the spring 340 can be adjusted to adjust the pressure applied by the positioning wheel 380 on the sheet material, thereby avoiding the sheet material from being easily deformed or damaged due to excessive pressure, thereby increasing the versatility of the sheet material conveying device with positioning function and being able to be used for sheets of different widths.

[0063] In addition, if Figure 3 and Figure 4 As shown, a locking nut 320 can be added to the adjusting bolt 310. When the position of the adjusting bolt 310 relative to the fixing seat 330 is adjusted, the locking nut 320 is screwed to make the locking nut 320 contact the fixing seat 330, thereby increasing the connection effect between the adjusting bolt 310 and the fixing seat 330 and preventing the adjusting bolt 310 from loosening easily.

[0064] In this embodiment, if Figure 4As shown, the adjusting bolt 310 is provided with a positioning portion, which is located at the end of the adjusting bolt 310 near the rocker arm 350. The positioning portion and the adjusting bolt 310 can be integrally formed or fixedly connected by screws. The positioning portion is cylindrical and is coaxially arranged with the adjusting bolt 310. The rocker arm 350 is provided with a positioning groove 351, and the opening of the positioning groove 351 is open in the direction of the rocker arm 350 near the adjusting bolt 310. The spring 340 is sleeved on the positioning portion, and one end of the spring 340 abuts the end face of the adjusting bolt 310, and the other end of the spring 340 extends into the positioning groove 351 and abuts the bottom surface of the positioning groove 351. This design facilitates the disassembly and assembly of the spring 340.

[0065] Of course, it is not excluded that in other embodiments, the elastic positioning mechanism 300 uses an elastic member and a positioning plate, and the positioning plate can elastically float along the second direction under the elastic force of the elastic member.

[0066] It can be understood that the function of the elastic positioning mechanism 300 is to allow sheets of different widths to pass through the positioning area, while the function of the first positioning mechanism 400 is to guide and position the sheet and determine the final position of the sheet after positioning on the horizontal plane.

[0067] In some embodiments, as Figure 1 and Figure 5 As shown, the sheet material conveying device with positioning function further includes a second positioning mechanism 200 .

[0068] The second positioning mechanism 200 is positioned near the feed end of the conveying plane. In this embodiment, the second positioning mechanism 200 is located in front of the first positioning mechanism 400 and the elastic positioning mechanism 300. Two second positioning mechanisms 200 are provided, symmetrically located on either side of the conveying mechanism 100 along the second direction. The second positioning mechanisms 200 are configured to initially position the sheet material on the conveying plane.

[0069] Specifically, the second positioning mechanism 200 includes a positioning block and a linear drive. The linear drive is mounted on the frame 110 of the conveying mechanism 100, and the output end of the linear drive is connected to the positioning block. When the linear drive is working, the output end of the linear drive can drive the positioning block to move along the second direction, thereby realizing the telescopic movement of the positioning block along the second direction. The positioning block is located above the conveying plane, and there is a certain upper and lower gap between the positioning block and the conveying plane, so that the positioning block can contact the sheet material on the conveying plane. By the simultaneous operation of the two linear drives, the two positioning blocks arranged opposite to each other along the second direction can move closer to each other to roughly position the sheet material on the conveying plane.

[0070] It is understandable that the linear drive member can be a linear drive device such as an electric cylinder or a pneumatic cylinder. After the sheet material is transferred to the conveying plane of the conveying mechanism 100 by a feeding mechanism such as a robot with a suction cup, the two second positioning mechanisms 200 can be activated. Through the driving action of the linear drive member, the two positioning blocks are moved closer to each other, and the sheet material located between the two positioning blocks is centered. Under the pushing action of the two positioning blocks, the sheet material moves a certain distance along the second direction, so that the sheet material is basically at the center position of the conveying plane along the first direction, thereby completing the preliminary positioning of the sheet material before the sheet material enters the positioning area, so that the sheet material can smoothly enter the positioning area.

[0071] After completing the centering of the sheet, the driving distance of the linear drive reaches the maximum stroke. At this time, the positioning block just touches the edge of the sheet, and the distance between the two positioning blocks in the second direction is slightly larger than the width of the sheet. Therefore, the sheet can complete the preliminary positioning work under the operation of the two second positioning mechanisms 200; then, under the operation of the conveying mechanism 100, the sheet continues to move along the first direction and is ready to enter the positioning area defined by the first positioning mechanism 400 and the elastic positioning mechanism 300, thereby completing the precise positioning of the sheet.

[0072] In some embodiments, as Figure 1 and Figure 5 As shown, the sheet material conveying device with positioning function also includes a photoelectric switch and a controller.

[0073] The controller is electrically connected to the photoelectric switches and all the second positioning mechanisms 200 via circuits. Furthermore, the photoelectric switches are configured to generate a detection signal when the sheet metal reaches the feed end, and the controller is configured to control the operation of the second positioning mechanisms 200 upon receiving the detection signal to perform preliminary positioning of the sheet metal.

[0074] A photoelectric switch is mounted on the frame 110 of the conveyor mechanism 100 and is located at the feed end. The photoelectric switch detects the presence of sheet material at the feed end through non-contact detection. The controller can be a PLC controller, a 51 single-chip microcomputer, or the like. When the photoelectric switch detects the presence of sheet material at the feed end, it generates a detection signal and transmits it to the controller. Upon receiving this detection signal, the controller generates a control command and sends it to the second positioning mechanism 200, causing it to operate and drive the positioning block toward the sheet material, thereby achieving preliminary positioning of the sheet material.

[0075] The sheet material conveying device with positioning function provided by the embodiment of the utility model has the advantages of simple structure, practical convenience, accurate positioning, etc. It is suitable for positioning batch sheets, such as sheets for manufacturing cover bodies, during the conveying process, to avoid the sheets from going astray during the conveying process, thereby ensuring that the next process, such as the printing process or the coding process, can smoothly produce qualified products.

[0076] After the sheet metal is sequentially transferred to the conveying plane of the conveyor mechanism 100 via the feed mechanism, it moves in a first direction from the feed end to the discharge end while the conveyor mechanism 100 is in operation. Once the sheet metal is at the feed end, the two second positioning mechanisms 200 perform preliminary positioning to complete the centering of the sheet metal. After completing the rough positioning, the sheet metal continues to move under the conveyance of the conveyor mechanism 100.

[0077] After the sheet material continues to move a certain distance in the first direction, it will enter the positioning area defined by the elastic positioning mechanism 300 and the first positioning mechanism 400. At this time, the elastically floating second positioning surface of the elastic positioning mechanism 300 can contact the sheet material and push the sheet material toward the first positioning mechanism 400, allowing the sheet material to contact the first positioning surface of the guide positioning plate 410. Under the guiding and positioning effect of the first positioning surface, the sheet material will move linearly along the first positioning surface, thereby completing the accurate positioning of each sheet material during the conveying process, thereby ensuring that the sheet material position can meet the requirements of the next process. After the precise positioning of the sheet material position is completed, the sheet material can be processed with a printed pattern or a coding pattern.

[0078] When encountering sheets of varying widths and S-shaped long sides, the function of the elastic positioning device can be fully utilized. With the help of the elastic floating characteristics of the second positioning surface, the positioning area formed between the second positioning surface and the first positioning surface has an automatic adjustment function. Therefore, when the width of the sheet changes, the position of the second positioning surface of the elastic positioning device in the second direction will also change accordingly to adapt to sheets of different widths. Through the automatic adjustment function of the positioning area, the sheet can be brought into contact with the first positioning surface and the second positioning surface respectively, and the sheet is allowed to pass through the positioning area smoothly, thereby completing the accurate positioning of the sheet.

[0079] Moreover, the position of the guide positioning plate 410 in the second direction and the angular position on the horizontal plane can be adjusted respectively by the linear adjustment component 430 and the angle adjustment component 420, thereby adjusting the positioning effect of the first positioning mechanism 400 on the sheet material so that the sheet material can meet the requirements of the next process for the sheet material position.

[0080] The sheet material conveying device with positioning function of this embodiment is suitable for positioning the sheet material during the conveying process, and has the effect of adaptive fine-tuning positioning for the sheet material with slight deviation. Moreover, the linear adjustment component 430 and the angle adjustment component 420 can be used to quickly adjust the sheet material to the correct position after it deviates from its position, thereby ensuring that the sheet material with a width deviation within a certain small range can maintain a parallel conveying state during the conveying process, ensuring that the sheet material does not deviate from the correct position required for processing.
