Description

Technical Field

[0001] This utility model belongs to the field of rubber roll material feeding technology, and in particular relates to a feeding component and feeding device. Background Technology

[0002] In the manufacturing process of photovoltaic modules, there is a gap in the EVA film at the lead-in location to allow the lead to pass through and be exposed. To fill the gap in the EVA film, small insulating pieces are usually used to cover it, preventing the molten material from being squeezed out of the gap after the film melts during lamination. To achieve automatic placement of these small pieces, an automatic feeding device for the small pieces is essential.

[0003] The prior art patent CN218802804U discloses a photovoltaic module insulation material feeding and cutting device. This device actively feeds materials through an automatic unwinding module. Small strips of material are automatically punched by a punching module, and then accurately fed by a roller feeding module. A receiving platform is connected to the output side of the roller feeding module. The roller feeding module accurately pushes the front end of the small strip of material onto the receiving platform according to a set length pitch. A cutting module is set above the receiving platform. The cutting module cuts the small strip of material into small pieces, thereby realizing automatic feeding. However, in actual use, it was found that because the small pieces are made of rubber, when driven by the roller feeding module, the head end of the small piece strip moves in the output direction on the receiving platform. When the small piece strip moves on the receiving platform, the lower surface of the small piece strip has a large contact area with the receiving platform. Due to the rubber material properties of the small piece strip, the head end is prone to sticking to the surface of the receiving platform and cannot be effectively pushed forward. This causes the small piece strip to arch on the receiving platform and become rolled up, resulting in the inability to cut correctly and effectively pick up and transport the material.

[0004] Therefore, it is necessary to provide a new small-piece feeding device to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a feeding component and feeding device that can effectively solve the problem of small strips of material being rolled up on the receiving platform.

[0007] Furthermore, the height difference between the first receiving platform and the second receiving platform is 0.8 to 3 times the thickness of the material; or, the height difference between the first receiving platform and the second receiving platform is 1 to 200 mm.

[0008] Furthermore, it also includes one or more of the following: a hot melt module, a strip buffer module, a punching module, and a cutting module; the unwinding module, the hot melt module, the strip buffer module, the punching module, the feeding module, and the cutting module are arranged sequentially along the strip conveying direction.

[0009] Furthermore, the first receiving platform is located on the output side of the cutting module; a second clearance slot is formed between the first receiving platform and the second receiving platform to avoid the falling of the cutter in the cutting module.

[0010] Furthermore, the unwinding module and the hot-melt module are disposed in a first height space, and the punching module, the feeding module, and the cutting module are disposed in a second height space, with the first height space located above the second height space; the input side of the strip buffer module is connected to the hot-melt module, and the output side is connected to the punching module; the unwinding module and the hot-melt module are arranged sequentially along a first direction, and the strip buffer module, the punching module, the feeding module, and the cutting module are arranged sequentially along a second direction, which is opposite to the first direction.

[0011] Furthermore, the feeding module includes a driving component, an active feeding roller that is driven by the driving component to rotate around the Y-axis, and a driven feeding roller that presses small pieces of material onto the active feeding roller.

[0012] Furthermore, the cutting module includes a first cylinder, a connecting plate driven by the first cylinder to move up and down, a cutter fixed below the connecting plate, and a floating pressure plate elastically floating on the connecting plate and located below the cutter; the floating pressure plate presses the two sides of the small piece of material strip at the cutting position of the cutter; the floating pressure plate is provided with a first avoidance groove to avoid the cutter passing through.

[0013] Another objective of this utility model is to provide a feeding device, comprising: The material conveyor line transports small pieces of material along the Y direction; The feeding assembly described above is located at the beginning of the feeding conveyor line; The material handling module picks up small pieces of material from the feeding assembly and places them onto the feeding conveyor line; The third camera is located above the end of the feeding conveyor line.

[0014] Furthermore, the feeding assembly includes a first small feeding assembly and a second small feeding assembly, located on both sides of the X direction at the beginning of the feeding conveyor line.

[0015] Furthermore, the material handling module includes an X-axis drive module, a support plate driven by the X-axis drive module to move along the X direction, and two sets of adsorption components fixed on the support plate and symmetrically arranged with the Y-axis as the axis of symmetry; the adsorption components include a second cylinder fixed on the support plate and a suction nozzle module driven by the second cylinder to move up and down.

[0016] Compared with existing technologies, the beneficial effects of this utility model's small-piece feeding device are as follows: through multi-dimensional structural optimization and layout design, it achieves high efficiency, stability, and compactness in the entire process of small-piece material conveying, cutting, and feeding. The core technical effects are reflected in the following four aspects: (1) Regarding the stability of the conveyor belt, the stepped height difference design of the first and second receiving platforms (the height difference is 0.8 to 3 times the thickness of the small piece of material) solves the problem of material roll-up of rubber material belt from the root through the triple mechanism of "forced separation, directional guidance, and smooth resistance reduction": it breaks the continuous pasting state between the material belt and the platform, and avoids the material belt from arching by fixing the transition posture. At the same time, it reduces the additional adhesion resistance of the feeding module. The test has verified that it can ensure that the material belt is accurately delivered to the cutting position without jamming, breakage or roll-up, thus ensuring the stability and reliability of the conveying process.

[0017] (2) In terms of material supply continuity and material change efficiency, the device relies on the alternating material supply mode of the first and second small material supply components, and the hot melt module between the unwinding module and the material belt buffer module completely eliminates the cumbersome threading operation during the traditional rewinding. Operators only need to hot melt bond the end of the old material belt to the beginning of the new material belt to complete the material change, which greatly shortens the material change time. At the same time, the active unwinding mode and the material belt buffer module work together to effectively avoid the failure of the rolling material feeding module, ensuring that the small material belt is transported stably without interruption for 24 hours, which significantly improves the overall material supply efficiency.

[0018] (3) Regarding the accuracy of small piece cutting position, the floating pressure plate design of the cutting module forms a precise action logic of "first pressing, then cutting, and then pulling the knife": the floating pressure plate first presses the two sides of the material strip cutting position to avoid the material strip shifting during cutting; when the cutter pulls it away upward after cutting, the floating pressure plate still maintains the pressing state, completely eliminating the problem of the cutter carrying up small pieces, ensuring that the small pieces after cutting accurately stay in the set area on the first receiving platform, providing a premise for the stable adsorption of the subsequent material handling module, and solving the industry pain point of easy displacement of rubber material strip after cutting.

[0019] (4) In terms of equipment space utilization, the device adopts a spatial layout strategy of "upper and lower layering + reverse arrangement": the unwinding module and the hot melt module are placed in the upper first height space, and the punching, feeding, cutting module and receiving platform are placed in the lower second height space. The unwinding and hot melt modules are arranged in the opposite direction to the buffer, punching and other modules. Without affecting the collaborative operation of each module, the horizontal floor area of ​​small material feeding components is greatly reduced. This is especially suitable for compact workshop layout scenarios and improves the equipment capacity per unit space. Attached Figure Description

Detailed Implementation

[0021] Example 1: Please refer to Figures 1-5This embodiment is a feeding device 100, including a feeding conveyor line 1 that conveys small pieces 200 along the Y direction, a first small piece feeding assembly 2 and a second small piece feeding assembly 3 located on both sides of the end of the feeding conveyor line 1 in the X direction, a picking and handling module 4 that picks up small pieces 200 from the first small piece feeding assembly 2 and the second small piece feeding assembly 3 and places them onto the feeding conveyor line 1, and a third camera (not shown in the figure) located above the end of the feeding conveyor line 1. The first small piece feeding assembly 2 and the second small piece feeding assembly 3 can alternately feed small pieces to achieve continuous and uninterrupted feeding.

[0022] The first small piece feeding assembly 2 and the second small piece feeding assembly 3 have the same structure, and both include an unwinding module 21, a material belt buffer module 22, a punching module 23, a feeding module 24 and a cutting module 25 arranged sequentially along the conveying direction of the small piece material belt 300, and a first receiving platform 26 arranged on the output side of the cutting module 25.

[0023] To facilitate quick roll changing for operators and avoid the cumbersome threading operation each time roll changing is performed, a heat-melting module 27 is also provided between the unwinding module 21 and the material belt buffer module 22. This allows operators to quickly heat-melt and bond the tail end of the small material belt 300 output from the old roll to the head end of the small material belt 300 of the new roll, eliminating the threading process and improving the convenience and efficiency of the material changing operation.

[0024] In this embodiment, the unwinding module 21 adopts an active unwinding mode, which, together with the material belt buffer module 22, can prevent the feeding module 24 from failing to feed the material while rolling, thus ensuring the effective conveying of the small material belt 300.

[0025] To reduce the horizontal area occupied by the small-piece feeding assembly, this embodiment places the unwinding module 21 and the hot-melt module 27 in a first height space, while the punching module 23, feeding module 24, cutting module 25, and first receiving platform 26 are all placed in a second height space. The first height space is located above the second height space. The input side of the strip buffer module 22 connects to the hot-melt module 27, and the output side connects to the punching module 23. The unwinding module 21 and the hot-melt module 27 are arranged sequentially along a first direction, while the strip buffer module 22, punching module 23, feeding module 24, cutting module 25, and first receiving platform 26 are arranged sequentially along a second direction, which is opposite to the first direction. Through the above-mentioned layout of the various modules, the height space is fully utilized to reduce the overall area occupied by the small-piece feeding assembly.

[0026] The feeding module 24 includes a drive unit 241, an active feeding roller 242 driven by the drive unit 241 to rotate around the Y-axis, and a driven feeding roller 243 that presses the small piece of material strip 300 onto the active feeding roller 242. The drive unit 241 drives the active feeding roller 242 to rotate, and the driven feeding roller 243 works in conjunction with the driven feeding roller 243 to accurately convey the small piece of material strip 300 toward the first receiving platform 26.

[0027] Since the small piece 200 needs to be picked up and placed on the subsequent feeding conveyor line to be transported to the small piece placement device after being pushed onto the first receiving platform 26, the position of the small piece 200 on the first receiving platform 26 cannot deviate from the set area, otherwise it cannot be effectively picked up. In order to ensure that the position of the small piece 200 on the first receiving platform 26 will not shift when the head end of the small piece material strip 300 is cut out, the structure of the cutting module 25 has been optimized in this embodiment. Specifically, the cutting module 25 includes a first cylinder 251, a connecting plate 252 driven by the first cylinder 251 to move up and down, a cutter 253 fixed below the connecting plate 252, and a floating pressure plate 254 elastically floating on the connecting plate 252 and located below the cutter 253; the floating pressure plate 254 presses the two sides of the small piece material strip 300 at the cutting position of the cutter 253. The floating pressure plate 254 is provided with a first clearance slot 2541 to allow the cutter 253 to pass through. During operation, the cutting module 25 first contacts the small piece of material strip 300. As the connecting plate 252 continues to descend, the cutter 253 passes through the first clearance slot 2541 on the floating pressure plate 254 and cuts out a small piece 300 onto the first receiving platform 26. Then, the connecting plate 252 moves upward, and the cutter 253 moves upward with the connecting plate 252 and is pulled out from inside the small piece of material strip 300. At this time, the floating pressure plate 254 still maintains its pressing effect on the small piece of material strip 300, effectively preventing the cutter 253 from lifting the cut-out small piece 200 upward when it is pulled out, thereby effectively preventing the small piece 200 from shifting on the first receiving platform 26 and ensuring the positional accuracy of the small piece 200. During this process, the small piece of material strip 300 is pressed by the floating pressure plate 254 before cutting, so as to effectively ensure that the position of the small piece is stable and does not shift.

[0028] The output side of the feeding module 24 is provided with a second receiving platform 28 for receiving small material strips 300; the first receiving platform 26 is connected to the output side of the second receiving platform 28, and a second clearance slot 29 is provided between the two to avoid the cutting blade 253 passing through.

[0029] The head of the small strip material 300 is conveyed by the feeding module 24, passing sequentially through the second receiving platform 28 and the first receiving platform 26, and stops at a predetermined position on the first receiving platform 26 to await cutting. Due to the material properties of the small strip material, the head of the small strip material 300 is prone to sticking to the surface of the receiving platform when moving on the first receiving platform 26 and the second receiving platform 28, and cannot be effectively pushed forward, causing the small strip material 300 to arch on the receiving platform and resulting in a winding phenomenon. In order to solve this technical problem, this embodiment optimizes the design of the first receiving platform 26 and the second receiving platform 28 by designing the first receiving platform 26 and the second receiving platform 28 as a stepped structure with a height difference, that is, the height of the first receiving platform 26 is lower than the height of the second receiving platform 28.

[0030] The height difference between the first receiving platform 26 and the second receiving platform 28 is used to solve the problem of material tangling during the conveying of small material strips. The core mechanism of this design is to break the adhesive force between the rubber strip and the platform at the source through physical separation and posture guidance, while controlling the transition posture of the strip to avoid arching and tangling. Specifically, it can be broken down into three key steps: (1) Forced separation – cutting off the continuous adhesive path: When the small piece of material strip 300 moves from the higher second receiving platform 28 to the lower first receiving platform 26, the height difference will cause the head of the material strip to detach from the surface of the second receiving platform 28 first, and then contact the first receiving platform 26. This process of “detaching first and then contacting” forcibly breaks the continuous adhesive state between the material strip and the receiving platform, avoiding the “drag resistance” caused by the entire material strip sticking tightly to the platform. This resistance is the core reason why the front end of the material strip does not move when the rear end is pushed, and thus the roll of material arches.

[0031] (2) Directional guidance – controlling the transition posture of the material strip: A reasonable height difference will provide a fixed "downward transition" path for the material strip, so that the material strip can only enter the first platform with the "front end tilting downward" posture, rather than being randomly attached. This directional posture can concentrate the force on the material strip in the "forward pushing" direction, avoid the upward lifting force generated by the front end due to the pasting, and eliminate the possibility of material roll-up from the perspective of movement posture.

[0032] (3) Smooth Drag Reduction – Reducing Additional Feeding Resistance: If the two receiving platforms are at the same height, the contact area between the rubber strip and the receiving platform is large and the adhesion is strong. The resistance that the feeding module 24 needs to overcome includes not only the inertia of the strip itself, but also the huge adhesive force, which can easily lead to "local accumulation" of the strip due to insufficient thrust. The height difference reduces the simultaneous contact area between the strip and the receiving platform, which greatly reduces the adhesive resistance, so that the thrust of the feeding module can be applied to the strip efficiently, ensuring that it moves smoothly to the cutting position.

[0033] However, the height between the first receiving platform 26 and the second receiving platform 28 needs to be designed reasonably. The height difference between the first receiving platform 26 and the second receiving platform 28 needs to balance "anti-sticking" and "smooth feeding". Too large or too small a difference will disrupt this balance and lead to new problems. If the height difference is too large, it will form a steep step. When the small piece of material strip 300 transitions from the higher second receiving platform 28 to the lower first receiving platform 26, the end of the strip is easily "stuck" or "damaged" by the edge of the step, which will hinder feeding. At the same time, the steep drop will cause the strip to generate greater stress during the transition, which may cause permanent deformation of the rubber strip and prevent it from reaching the cutting position normally. If the height difference is too small, it will not be able to effectively break the adhesive force between the rubber strip and the platform surface. The strip will still move along the two receiving platform surfaces, and the original problems of "end sticking and arched winding" cannot be solved, making the optimized design meaningless. In this embodiment, the height difference between the first receiving platform 26 and the second receiving platform 28 is 0.8 to 3 times the thickness of the small material piece, or the height difference between the first receiving platform 26 and the second receiving platform 28 is 1 to 200 mm, for example, 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 15 mm, 20 mm, 30 mm, 40 mm, 60 mm, 80 mm, 100 mm, 150 mm, and 200 mm. Experimental tests have shown that within this height difference range, the small material strip can smoothly pass through the second receiving platform 28 and accurately reach the designated position on the first receiving platform 26 without any material tangling.

[0034] The material handling module 4 includes an X-axis drive module 41, a support plate 42 driven by the X-axis drive module 41 to move along the X-direction, and two sets of adsorption components 43 fixed on the support plate 42 and symmetrically arranged about the Y-axis. Each adsorption component 43 includes a second cylinder 431 fixed on the support plate 42 and a suction nozzle module 432 driven by the second cylinder 431 to move up and down. The two sets of adsorption components 43 adsorb small pieces 200 output from the first small piece feeding component 2 and the second small piece feeding component 3, respectively. When the support plate 42 is close to the output side of the first small piece feeding component 2, one set of adsorption components 43 picks up the small piece 200; when the support plate 42 is close to the output side of the second small piece feeding component 3, the other set of adsorption components 43 picks up the small piece 200.

[0035] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
