Description

Technical Field

[0001] This invention relates to the technical field of sheet splitting, and more particularly to a sheet splitting mechanism, a feeding device, and a processing system. Background Technology

[0002] In the production equipment for flexible components such as FPC flexible boards, paper, and substrates, multiple flexible components are stacked together. Due to factors such as the air being expelled between the flexible components to form a vacuum, their light weight, static electricity, and stickiness, multiple flexible components are prone to sticking together. This often results in multiple flexible components being picked up at once during the pick-up and transfer process, affecting the normal operation of subsequent processes. Summary of the Invention

[0003] In view of this, the present invention provides a sheet-separating mechanism, a feeding device and a processing system to solve the technical problem that multiple flexible parts are often picked up during the existing flexible part picking process.

[0004] To solve the above-mentioned technical problems, the first technical solution adopted by the present invention is as follows:

[0005] A sheet separation mechanism is provided, which is capable of adsorbing a single flexible element from a plurality of flexible elements. The sheet separation mechanism includes a connecting plate assembly and at least two adsorption elements. Each adsorption element is spaced apart from the connecting plate assembly along the length direction of the connecting plate assembly. The end face of each adsorption element away from the connecting plate assembly is an adsorption surface, and each adsorption surface is arranged in the same direction. At least one adsorption surface is not on the same horizontal plane as the other adsorption surfaces, so that when adsorbing multiple flexible elements, gaps are generated by causing each flexible element to bend to different degrees, thereby separating the sheets.

[0006] Each of the adsorption elements is provided with a buffer so that each adsorption surface at different levels can adhere to the multiple flexible sheets with varying degrees of buffering.

[0007] In some embodiments of the sheet-separating mechanism, when the number of adsorption elements is greater than or equal to three, each adsorption element is arranged at equal intervals along a first direction on the connecting plate assembly, the adsorption surfaces of two adjacent adsorption elements are spaced apart, and the adsorption surfaces of two adsorption elements separated by one adsorption element are coplanar.

[0008] In some embodiments of the sheet-splitting mechanism, each of the adsorption elements is slidably connected to the connecting plate assembly so as to adjust the position of each of the adsorption surfaces. The sheet-splitting mechanism also includes a plurality of fastening components, each of which is used to fix each of the adsorption elements to the connecting plate assembly in a one-to-one correspondence.

[0009] In some embodiments of the sheet-splitting mechanism, the connecting plate assembly has multiple connecting holes that penetrate the connecting plate assembly, and each of the adsorption elements is correspondingly inserted into each of the connecting holes. Each of the fastening components includes a first nut and a second nut that are threaded onto the adsorption element. The first nut and the second nut are located on opposite sides of the connecting plate assembly so that the adsorption element can be fixed to the connecting plate assembly by clamping the connecting plate assembly.

[0010] In some embodiments of the sheet-splitting mechanism, the connecting plate assembly includes a first plate and a plurality of second plates. The first plate extends along the first direction, and each of the second plates is detachably connected to the first plate and is equally spaced along the first direction. The first plate is provided with a plurality of mounting positions for mounting the second plates along the second direction, and the first direction and the second direction are arranged at an angle. Each of the connecting holes is provided one-to-one with each of the second plates.

[0011] In some embodiments of the sheet-splitting mechanism, the sheet-splitting mechanism further includes an air-blowing assembly capable of blowing air toward the gap, thereby causing each of the adsorption elements to adsorb a single sheet of the flexible member.

[0012] In some embodiments of the sheet-splitting mechanism, the sheet-splitting mechanism further includes a first drive module and a second drive module. The output end of the first drive module is connected to the connecting plate assembly and is used to drive the connecting plate assembly to move each of the adsorption elements closer to or away from the flexible member. The output end of the second drive module is connected to the first drive module and is used to drive the first drive module so that the flexible member can be transported through each of the adsorption elements. The air blowing assembly is located on the moving path of the first drive module.

[0013] To solve the above-mentioned technical problems, the second technical solution adopted by the present invention is as follows:

[0014] A feeding device includes the sheet-splitting mechanism described in the above embodiment. The feeding device also includes a material platform for supporting multi-layer flexible parts for adsorption by the sheet-splitting mechanism.

[0015] In some embodiments of the feeding device, the sheet separating mechanism further includes an air blowing assembly capable of blowing air toward the gap, thereby causing each of the adsorption elements to adsorb a single sheet of the flexible part;

[0016] The feeding device further includes a first pressing assembly, which includes a first pressing drive and a pressure plate. The first pressing drive is installed on the material platform, and the output end of the first pressing drive is connected to the pressure plate. The first pressing drive is used to drive the pressure plate to move closer to or away from the material platform to press the flexible component on the material platform. The air blowing assembly is installed on the pressure plate.

[0017] In some embodiments of the feeding device, the pressure plate has a protrusion on the side opposite to the material table, and the sidewall of the protrusion abuts against the end of the flexible member to position the flexible member.

[0018] The pressure plate body has an air outlet on its end face away from the protrusion and close to the flexible member. An air inlet is provided on the protrusion. The pressure plate has a channel connecting the air outlet and the air inlet. The air blowing assembly is installed on the protrusion and communicates with the air inlet.

[0019] To solve the above-mentioned technical problems, the second technical solution adopted by the present invention is as follows:

[0020] A processing system includes a cover film cutting machine, the cover film cutting machine including a feeding device as described in any one of claims 8-10, the feeding device being disposed on the cover film cutting machine, the feeding device being used for separating FPC flexible boards and feeding single FPC flexible boards onto the cover film cutting machine.

[0021] Implementing the embodiments of the present invention will have at least the following beneficial effects:

[0022] The aforementioned sheet-separating mechanism, applied to the feeding device and processing system, enables both the device and the feeder to pick up single flexible parts. Specifically, the sheet-separating mechanism of this invention employs at least two adsorption elements, with at least one adsorption surface of each element not on the same horizontal plane as the others. For example, when placed horizontally, the adsorption surfaces of these elements are at different heights. During adsorption, the buffer element ensures that each adsorption surface can hold the flexible part. Then, when the adsorption element is lifted, the different heights of the adsorption surfaces cause the multiple bonded flexible parts to bend to varying degrees during adsorption. This bending creates gaps, thus separating the bonded flexible parts and achieving the sheet-separating purpose. This solves the technical problem of frequently picking up multiple flexible parts during existing flexible part picking processes. Attached Figure Description

[0036] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many other different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0037] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] like Figure 3 , 6 As shown in Figure 8, in one embodiment of the sheet-separating mechanism 20, the sheet-separating mechanism 20 includes a connecting plate assembly 21 and at least two adsorption elements 22. Each adsorption element 22 is spaced apart from the connecting plate assembly 21 along its length. The end face of each adsorption element 22 away from the connecting plate assembly 21 is an adsorption surface, and all adsorption surfaces are arranged in the same direction. At least one adsorption surface is not on the same horizontal plane as the other adsorption surfaces, so that when multiple flexible parts are adsorbed, gaps are created by causing the flexible parts to bend to different degrees, thus separating them. Each adsorption element 22 is provided with a buffer, so that each adsorption surface on different horizontal lines can adhere to multiple flexible parts with different degrees of buffering.

[0040] In this embodiment, by setting at least two adsorption elements 22, and at least one of the adsorption surfaces of these adsorption elements 22 is not on the same horizontal plane as the other adsorption surfaces, it can be understood that, taking horizontal placement as an example, the height positions of the adsorption surfaces of these adsorption elements 22 are different. Thus, during adsorption, firstly, due to the action of the buffer, each adsorption surface can adsorb the flexible part. Then, when the adsorption element 22 is lifted, due to the different heights of the adsorption surfaces, the multiple flexible parts that are stuck together will bend when adsorbed. When the flexible parts bend to different degrees, gaps will inevitably be generated, thereby achieving the purpose of separating the stuck flexible parts and thus achieving the purpose of separation.

[0041] In one embodiment of the sheet-separating mechanism 20, when the number of adsorption elements 22 is greater than or equal to three, each adsorption element 22 is arranged at equal intervals along the first direction on the connecting plate assembly 21, the adsorption surfaces of two adjacent adsorption elements 22 are spaced apart, and the adsorption surfaces of two adsorption elements 22 separated by one adsorption element 22 are coplanar.

[0042] Specifically, refer to Figure 6 As shown, when the number of adsorption elements 22 is greater than or equal to three, the adsorption surface of each adsorption element 22 can be divided into two groups, which are located at different heights. The arrangement is more orderly, forming a wave shape, which also forces the flexible parts to form a wave shape, making it easier to separate multiple flexible parts.

[0043] Preferably, combined with Figure 3 and Figure 6 As shown, the driving direction of the second driving module 24 is perpendicular to the first direction, that is, the first direction can be parallel to the width direction of the flexible component.

[0044] In one embodiment of the sheet-splitting mechanism 20, each adsorption element 22 is slidably connected to the connecting plate assembly 21 so that the position of each adsorption surface can be adjusted. The sheet-splitting mechanism 20 also includes a plurality of fastening components 25, each fastening component 25 being used to fix each adsorption element 22 to the connecting plate assembly 21 in a one-to-one correspondence.

[0045] In this embodiment, by setting each adsorption element 22 to slide relative to the connecting plate assembly 21, and fixing each adsorption element 22 and the connecting plate assembly 21 by multiple fastening components 25 after the position is determined, the position of the adsorption element 22 can be easily adjusted, so that each adsorption surface of each adsorption element 22 meets the requirements of the above embodiment, which is convenient for the staff to adjust.

[0046] It is understood that the sliding of each adsorption element 22 is to adjust the position of the adsorption surface. Therefore, when the feeding mechanism 20 is set horizontally, the sliding direction of each adsorption element 22 is parallel to the vertical direction. Preferably, the sliding direction of each adsorption element 22 is perpendicular to the first direction.

[0047] In one embodiment of the sheet-splitting mechanism 20, such as Figure 6 As shown, the connecting plate assembly 21 has multiple connecting holes that penetrate the connecting plate assembly 21. Each adsorption element 22 is correspondingly inserted into each connecting hole. Each fastening assembly 25 includes a first nut 251 and a second nut 252 that are threaded onto the adsorption element 22. The first nut 251 and the second nut 252 are located on opposite sides of the connecting plate assembly 21 so that the adsorption element 22 can be fixed to the connecting plate assembly 21 by clamping the connecting plate assembly 21.

[0048] Specifically, in conjunction with the previous embodiments, the extension direction of the connecting hole can be vertical. Specifically, when the adsorption element 22 needs to adjust the height of the adsorption surface, the first nut 251 and the second nut 252 can be loosened first to increase the gap between the first nut 251 and the second nut 252. Then, it can be moved along the extension direction of the connecting hole, i.e., the vertical direction. After the position of the adsorption element 22 is determined, the first nut 251 and the second nut 252 are turned on respectively so that the first nut 251 and the second nut 252 press against the connecting plate assembly 21 to complete the position adjustment of the adsorption element 22. The adjustment method is simple and the connection with the connecting plate assembly 21 is stable.

[0049] In one embodiment of the sheet-splitting mechanism 20, the connecting plate assembly 21 includes a first plate 211 and a plurality of second plates 212. The first plate 211 extends along a first direction, and each second plate 212 is detachably connected to the first plate 211 and is equally spaced along the first direction. The first plate 211 is provided with a plurality of mounting positions for mounting the second plates 212 along a second direction. The first direction and the second direction are arranged at an angle, and each connecting hole is correspondingly provided on each second plate 212.

[0050] In this embodiment, in conjunction with the previous embodiments, the first plate 211 can be a rectangular plate. Taking the horizontal placement of the first plate 211 as an example, the first direction can be parallel to the length direction of the connecting plate assembly 21, such as... Figure 1 In the X direction, the length of the connecting plate assembly 21 can correspond to the width of the flexible component, and the second direction can be parallel to the width direction of the connecting plate assembly 21, such as... Figure 1 In the Y direction, the connecting plate assembly 21 is provided with a first plate 211 and multiple second plates 212, and the position of the second plates 212 can be adjusted along the second direction to facilitate adaptation and adjustment by the staff. Specifically, multiple installation positions can be formed by strip-shaped holes extending along the second direction, and fixing can be done by bolts and nuts.

[0051] In one embodiment of the sheet separation mechanism 20, the sheet separation mechanism 20 further includes an air blowing assembly 30, which can blow air toward the gap to separate the flexible parts that are stuck together, while retaining the individual flexible parts that are adsorbed by each adsorption element 22.

[0052] In conjunction with the previous embodiments, even if the two flexible parts are stuck together and not completely separated under the action of each adsorption element 22, a gap will inevitably be generated. In this embodiment, by setting the air blowing component 30, air can be blown toward the gap to cause the two flexible parts to separate.

[0053] It should be noted that when each adsorption element 22 adsorbs the flexible parts, it may adsorb a single flexible part or multiple flexible parts that are stuck together. Regardless of whether it is a single or multiple parts, the air blowing assembly 30 will blow air. Preferably, in one embodiment of the sheet separating mechanism 20, the sheet separating mechanism 20 further includes a weight sensor. The weight sensor is used to sense the weight of the adsorbed flexible parts. The weight sensor is communicatively connected to the air blowing assembly 30. When the weight sensor senses that the weight of the adsorbed flexible parts exceeds that of a single flexible part, the air blowing assembly 30 starts blowing air.

[0054] In one embodiment of the sheet-splitting mechanism 20, the sheet-splitting mechanism 20 further includes a first driving module 23 and a second driving module 24. The output end of the first driving module 23 is connected to the connecting plate assembly 21 and is used to drive the connecting plate assembly 21 to move each adsorption element 22 closer to or away from the flexible part. The output end of the second driving module 24 is connected to the first driving module 23 and is used to drive the first driving module 23 so that the flexible part can be conveyed through each adsorption element 22.

[0055] In this embodiment, by setting a first drive module 23 and a second drive module 24, the sheet-separating mechanism 20 can have a feeding function. Specifically, the driving direction of the first drive module 23 can be parallel to the vertical direction, thereby moving closer to or further away from the horizontally placed flexible component. The driving direction of the second drive module 24 can be parallel to the horizontal direction, specifically parallel to the length direction of the flexible component, thereby driving the flexible component to be fed along its own length direction. Specifically, the first drive module 23 can be a cylinder module, which drives the connecting plate assembly 21 to rise and fall by connecting the conveying end to the connecting plate assembly 21. The second drive module 24 can be in the form of a cylinder module, a lead screw module, a linear motor, etc.

[0056] When the second drive module 24 is a lead screw module, in non-standard automated production equipment, due to the machining accuracy error of the parts, the central axes of the lead screw component 244 and the nut component 245 are not on the same line, causing jamming and uneven operation. When the existing lead screw and nut device jams, the height difference between the central axes of the lead screw component 244 and the nut component 245 is adjusted by adding a gap plate, which is not convenient for operators to adjust.

[0057] To address the aforementioned problems, the present invention also relates to a lead screw module, namely a second drive module 24, specifically, as follows: Figure 7-8 As shown, in one embodiment of the second drive module 24, the second drive module 24 includes a base plate 241, a slide plate 242, a drive motor 243, a lead screw component 244, a nut component 245, and an adjusting component 246. The drive motor 243 is mounted on the base plate 241 and is connected to the lead screw component 244 for transmission, thereby driving the lead screw component 244 to rotate. The nut component 245 is sleeved on the lead screw component 244 and threadedly connected to it. The adjusting component 246 detachably connects the nut component 245 and the slide plate 242. The slide plate 242 is connected to the nut component 245 via the adjusting component 246 so that it can move with the nut component 245. The adjusting component 246 can adjust the radial movement of the nut component 245 relative to the lead screw component 244, so that the nut component 245 is coaxial with respect to the lead screw component 244.

[0058] In this embodiment, by setting the adjusting component 246, firstly, the connection relationship of the existing lead screw module is changed. In this embodiment, the sliding plate 242 is not directly connected to the nut component 245, but is indirectly connected to the nut component 245 through the adjusting component 246. Secondly, the adjusting component 246 can adjust the nut component 245 to move radially relative to the lead screw component 244, thereby achieving the purpose of adjusting the nut component 245 and the lead screw component 244 to be coaxial, thereby eliminating jamming, facilitating adjustment by the operator, and ensuring smooth operation of the lead screw and nut device.

[0059] Specifically, the adjusting component 246 includes an adjusting plate 2461, a first adjusting member 2462, and a second adjusting member 2463. The adjusting plate 2461 has a strip-shaped hole 24611 and a circular hole 24612. The first adjusting member passes through the strip-shaped hole 24611 and is detachably connected to the sliding plate 242. The second adjusting member 2463 passes through the circular hole 24612 and is detachably connected to the nut component 245. Thus, through the actions of the first adjusting member and the second adjusting member 2463, the adjusting plate 2461 acts as an intermediary, connecting the adjusting plate 2461 and the nut component 245 together.

[0060] Taking the overall module placed horizontally as an example, when horizontal adjustment is required, the first adjusting component is turned to disengage the adjusting plate 2461 from the sliding plate 242. Then, the adjusting plate 2461 is driven horizontally. Through the connecting action of the second adjusting components 2463 and 2462, the nut component 245 can be adjusted. After adjustment, the adjusting plate 2461 and the sliding plate 242 are reconnected through the first adjusting component. It can be understood that the extension direction of the strip hole 24611 is horizontal, which facilitates the connection with the sliding plate 242 after the adjusting plate 2461 is moved. When vertical adjustment is required, the second adjusting component 2463 and 2462 can be loosened or tightened vertically to apply force to or release part of the force on the nut component 245, thereby achieving the purpose of adjustment.

[0061] Preferably, there are four strip holes 24611 and four circular holes 24612, located at the four corners of the adjusting plate 2461. Correspondingly, there are also four first adjusting members and four second adjusting members 2463 and 2462, so that the first adjusting member corresponds to the strip member and the second adjusting member 2463 and 2462 corresponds to the circular hole 24612.

[0062] Specifically, both the first adjusting member and the second adjusting member 24632462 can be bolts.

[0063] The present invention also relates to a feeding device, including the sheet-splitting mechanism 20 in the previous embodiment, and a material platform 11 for supporting multi-layer flexible parts for the sheet-splitting mechanism 20 to absorb.

[0064] By employing the sheet-splitting mechanism 20 in the above embodiments, the feeding device can pick up only a single flexible part during the feeding process, which facilitates subsequent processing.

[0065] In one embodiment of a feeding device, such as Figure 1-5 As shown, the feeding device also includes a first pressing assembly 12, which includes a first pressing drive 121 and a pressure plate 122. The first pressing drive 121 is mounted on the material platform 11, and its output end is connected to the pressure plate 122. The first pressing drive 121 is used to drive the pressure plate 122 closer to or further away from the material platform 11 to press against the flexible parts on the material platform 11. An air blowing assembly 30 is mounted on the pressure plate 122.

[0066] Specifically, in this embodiment, the material platform 11 and the first pressing component 12 can form a material storage mechanism 10. By setting the first pressing component 12, the flexible parts can be pressed down. By installing the air blowing component 30 on the pressure plate 122, it can be convenient to cooperate with the sheet separating mechanism 20. For example, the position of the pressure plate 122 can be set on the path of the sheet separating mechanism 20 to transport the flexible parts. In this way, the connecting plate component 21 can move closer to or further away from the air blowing component 30 under the drive of the second drive module 24. When air blowing is required, the second drive module 24 can drive the connecting plate component 21 to bond multiple layers of flexible parts, so that the gap between the thickness directions of the flexible parts can be aligned with the air blowing component 30.

[0067] Understandably, when the sheet-splitting mechanism 20 needs to pick up and load materials, the first pressing component 12 can release the flexible part.

[0068] In one embodiment of the feeding device, the pressure plate 122 has a protrusion 1221 on the side opposite to the material table 11. The sidewall of the protrusion 1221 abuts against the end of the flexible component to position the flexible component. The pressure plate 122 body has an air outlet 1224 on its end face away from the protrusion 1221 and close to the flexible component. An air inlet 1225 is provided on the protrusion 1221. The pressure plate 122 has a channel connecting the air outlet 1224 and the air inlet 1225. The air blowing assembly 30 is installed on the protrusion 1221 and communicates with the air inlet 1225.

[0069] In this embodiment, by installing the air blowing assembly 30 on the protrusion 1221, the air blowing assembly 30 can be avoided from occupying the space above the pressure plate 122, thereby making it easier for the sheet material to pass over the first pressing assembly 12. Especially when the sheet material is a flexible part such as FPC, the feeding mechanism 20 drags the flexible part, and the air blowing assembly 30 protruding on the pressure plate 122 poses a risk of scratching the flexible part.

[0070] Furthermore, in order to prevent the pressure plate 122 from scratching the material, an arc-shaped portion 1226 may be provided at the end of the pressure plate 122 relative to the second pressing component 13. The arc-shaped portion 1226 protrudes from the end of the pressure plate 122, and the air outlet 1224 is provided on the body of the pressure plate 122. Air can also be blown onto the flexible part through the air outlet 1224, which can further prevent the flexible part from being scratched.

[0071] In conjunction with the previous embodiments, the material platform 11 and the first pressing component 12 can form a material storage mechanism 10. However, in the production equipment for processing FPC ultra-long flexible boards and other sheet materials, because the length of the processed object is large and uncertain, conventional production equipment has great limitations in making a material storage mechanism of the corresponding length according to the product length. It cannot be applied if the product length changes slightly.

[0072] Therefore, the present invention also relates to a material storage mechanism 10, which together with the sheet-separating mechanism 20 in the previous embodiment constitutes a feeding device, such as... Figure 1-2 As shown, in one embodiment of the material storage mechanism 10, the material storage mechanism 10 includes a material platform 11, a first pressing assembly 12, and a second pressing assembly 13. The material platform 11 can support at least one end of the sheet material. The first pressing assembly 12 and the second pressing assembly 13 are respectively installed at a distance from the material platform 11. The first pressing assembly 12 can press against the end of the sheet material. The second pressing assembly 13 can press against the middle section of the sheet material.

[0073] In this embodiment, a second pressing component 13 is added on the basis of the previous embodiment, so that it can press on the end and middle of the plate. Thus, when the plate is placed on the material platform 11, even if the length of the plate exceeds the length of the material platform 11, it can be clamped on the material platform 11 by the first pressing component 12 and the second pressing component 13, thereby achieving the purpose of material storage and solving the technical problem that the existing material storage mechanism 10 cannot use plates of various lengths.

[0074] It is understood that the extension length of the material platform 11 in this embodiment can be shorter than that of the material. Under the pressing action of the first pressing component 12 and the second pressing component 13, the material can be clamped and fixed. Therefore, the material platform 11 only needs to be able to support part of the material. The material storage mechanism 10 in this embodiment is more universal than the existing one.

[0075] In addition, for ease of description, unless otherwise specified, the following embodiments will use the example of the material platform 11 being placed horizontally.

[0076] In one embodiment of the storage mechanism 10, such as Figure 4 As shown, the first pressing assembly 12 includes at least two pressing mechanisms arranged side by side. Each pressing mechanism includes a first pressing drive 121 and a pressing plate 122. The first pressing drive 121 is mounted on the material table 11. The output end of the first pressing drive 121 is connected to the pressing plate 122 and is used to drive the pressing plate 122 to move in the vertical direction to approach or move away from the material table 11. The pressing plate 122 has a protrusion 1221 on the side opposite to the material table 11. The protrusion 1221 can abut against the end of the material to position the material.

[0077] In this embodiment, the driving direction of the first pressing component 12 is vertical. By providing a protrusion 1221 on the pressing plate 122, the side wall of the protrusion 1221 can abut against the end of the board, thereby achieving the purpose of positioning the board. For example, when the worker places the board on the material table 11, the worker can abut one end of the board in his hand against the protrusion 1221, and then place the other part of the board flat on the material table 11. This ensures that the board is placed in the same position each time, and the positioning method is simple and convenient for operation.

[0078] Preferably, multiple protrusions 1221 can be provided, and the multiple protrusions 1221 can be arranged in a certain direction, which can be parallel to the end extension direction of the plate. For example, if the plate is rectangular and the material platform 11 is also rectangular, the multiple protrusions 1221 can be arranged in the width direction of the material platform 11.

[0079] Specifically, in this embodiment, the protrusion 1221 can be a columnar structure, such as a cylindrical, square, or arbitrary polygonal column, and can be used to position the plate by making line contact or surface contact with the plate.

[0080] In one embodiment of the storage mechanism 10, such as Figure 4 As shown, the pressure plate 122 body has a pressure surface 1223 on one side opposite the material table 11, and the protrusion 1221 opposite the second pressure component 13 is a positioning surface 12211, with the pressure surface 1223 perpendicular to the positioning surface 12211. The surface of the material table 11 used to support the material is the support surface, and the positioning surface 12211 is perpendicular to the support surface.

[0081] In this embodiment, by setting the positioning surface 12211, the positioning surface 12211 can form a surface contact with the board, with a large contact area, which can better position the board and thus achieve the effect of straightening the board. The pressing surface 1223 is perpendicular to the positioning surface 12211, and the two can form an L-shaped notch, which facilitates the positioning of the pressing plate 122 and pressing against the board.

[0082] In one embodiment of the storage mechanism 10, such as Figure 4 As shown, the end of the pressure plate 122 away from the second pressing assembly 13 is provided with a protrusion 1222. The first pressing assembly 12 also includes a vertical plate 123, which is connected to the material table 11. The first pressing drive 121 is installed on the material table 11 through the vertical plate 123, and the first pressing drive 121 is located between the vertical plate 123 and the protrusion 1221. The side of the vertical plate 123 away from the second pressing assembly 13 is attached to the protrusion 1222 to guide the movement of the protrusion 1222.

[0083] In this embodiment, by setting the upright plate 123, it is possible to facilitate the vertical installation of the first pressing drive component 121, and to guide the movement of the protruding plate 1222 and thus the pressing plate 122 by cooperating with the protruding plate 1222 on the pressing plate 122. With the driving action of the first pressing component 12, the pressing plate 122 can be raised and lowered smoothly.

[0084] Specifically, the protruding plate 1222 and the pressure plate 122 can be in surface contact. In order to reduce the friction between the protruding plate 1222 and the pressure plate 122, at least one of the protruding plate 1222 and the pressure plate 122 can be treated by means of coating or other methods.

[0085] In one embodiment of the storage mechanism 10, such as Figure 2 As shown, the material storage mechanism 10 also includes a sensor 14. The sensor 14 is installed on the side of the material table 11 away from the material. The material table 11 has a through hole 111 through the material table 11 at the position corresponding to the sensor 14. The sensing end of the sensor 14 can detect whether there is a material on the material table 11 through the through hole 111.

[0086] In this embodiment, by setting sensor 14, the presence of a board on the material table 11 can be detected through the through hole 111, thereby reminding the staff to place the board.

[0087] Specifically, the material platform 11 can be a U-shaped plate frame structure, and the opening of the material platform 11 faces the ground. The sensor 14 can be installed on the plate or frame, and the plate or frame can be connected to both sides of the U-shaped plate frame of the material platform 11, so that the sensor 14 corresponds to the through hole 111. Preferably, the sensor 14 can also be partially embedded in the through hole 111 for easy positioning and installation.

[0088] In one embodiment of the storage mechanism 10, such as Figure 1-2 As shown, the material storage mechanism 10 also includes two edge strips 15, which are connected one-to-one to the two sides of the material platform 11. Both edge strips 15 are arranged along the extension direction of the material platform 11, and the two edge strips 15 and the material platform 11 form a storage space that can accommodate the material.

[0089] In this embodiment, by setting two edge strips 15, a U-shaped structure can also be formed on the material platform 11. In this way, the board on the material platform 11 will be limited by the edge strips 15 on both sides. In addition, with the positioning function of the protrusion 1221 in the previous embodiment, the board can be straightened, which makes it convenient for workers to place the board and also facilitates the subsequent automated feeding.

[0090] Preferably, at least one of the two edge strips 15 is detachably connected to the material table 11, so that multiple positions for installing the edge strips 15 are provided on the material table 11, and the spacing between the two edge strips 15 will change in different positions, thereby accommodating plates of different widths.

[0091] In one embodiment of the storage mechanism 10, such as Figure 1 As shown, the material storage mechanism 10 also includes a cover plate 16, which covers the two side strips 15 and is located on the side of the second pressing assembly 13 away from the first pressing assembly 12.

[0092] In this embodiment, the cover plate 16 is located on the side away from the first pressing component 12 of the sheet material. The first pressing component 12 corresponds to one end of the sheet material, so the cover plate 16 is close to the other end of the sheet material. However, it should be noted that the cover plate 16 does not correspond to the other end of the sheet material. As in the previous embodiment, the sheet material can protrude outside the material table 11. In this embodiment, by setting the cover plate 16, the cover plate 16, the material table 11, and the two edge strips 15 can form a channel, which facilitates guiding the movement of the sheet material away from the end of the first pressing component 12. The cover plate 16 can also prevent the part of the sheet material protruding outside the material table 11 from deviating during the movement.

[0093] In one embodiment of the storage mechanism 10, such as Figure 1 As shown, the material is an FPC material. The material storage mechanism 10 also includes a guide plate 17. The guide plate 17 is connected to the material table 11 away from the first pressing component 12. The guide plate 17 is used to support the material. The guide plate 17 and the material table 11 are set at an angle. The angle between the guide plate 17 and the material table 11 is greater than 90° and less than 180°.

[0094] Based on the previous embodiments, it can be understood that the guide plate 17 in this embodiment is close to the tail of the material. As mentioned in the previous embodiments, the length of the material is not fixed and can protrude beyond the material table 11. When the material is a flexible circuit board or other bendable material, by setting the guide plate 17 at an angle to the material table 11, the material can hang down smoothly under the guidance of the guide plate 17, avoiding damage to the material.

[0095] In conjunction with the above embodiments, the feeding device can store boards of different specifications through the storage mechanism 10. In this embodiment, the feeding device is also provided with a feeding mechanism 20. The feeding mechanism 20, in conjunction with the movement of the first pressing component 12 and the second pressing component 13, can extract a single board from the material table 11 and transport it to external devices such as the cutting device for subsequent operations. By adopting the cooperative mode of the feeding mechanism 20, the first pressing component 12 and the second pressing component 13 in this embodiment, the operation of the first pressing component 12 and the second pressing component 13 is simple and can be completed in one cycle, thereby facilitating the feeding mechanism 20 to retrieve materials. Combined with the fact that the storage mechanism 10 itself has the effect of convenient material storage, this further makes the feeding device in this embodiment have the technical effect of convenient material storage and retrieval.

[0096] For ease of understanding, the feeding method of the feeding device in this embodiment is described here. Initially, the first pressing component 12 is located in the first pressing position and the second pressing component 13 is located in the second pressing position. During the feeding process, the output end of the feeding mechanism 20 first moves between the first pressing component 12 and the second pressing component 13. Then, the first pressing component 12 moves to the first movable position. At the same time or after the first pressing component 12 moves to the first movable position, the feeding mechanism 20 can pick up one end of the board from the material table 11. Then, the first pressing component 12 returns to the first pressing position. After the first pressing component 12 returns to the first pressing position, the second pressing component 13 moves from the second pressing position to the second movable position, thereby releasing the middle section of the board. Finally, after the second pressing component 13 moves to the second movable position, the feeding mechanism 20 can pull the end of the board to drive the board as a whole to move and feed the board. It should be emphasized that, in order to prevent the board from sliding due to factors such as gravity, one of the first pressing component 12 and the second pressing component 13 is always pressing against the board throughout the entire feeding process.

[0097] This invention also relates to a processing system, including a cover film cutting machine. The cover film cutting machine includes the feeding device described in the above embodiments. The feeding device is disposed on the cover film cutting machine and is used for sheeting FPC flexible boards and feeding single FPC flexible boards onto the cover film cutting machine. By using the feeding device described in the above embodiments, it is possible to avoid feeding multiple FPC flexible boards at once, which could lead to cutting errors in the cover film cutting machine. Furthermore, the sheeting efficiency is high, thereby improving the overall production efficiency of the processing system.

[0098] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
