Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material conveying, in particular to an automatic feeding and scanning pipeline with dynamic adjustment function. BACKGROUND

[0002] In the field of automation production, the automatic feeding and scanning pipeline as the core equipment of material conveying and information collection is widely used in the industries of plate processing and electronic manufacturing.

[0003] At present, the traditional pipeline is difficult to adapt to the dynamic demand of multi-specification plates. The current mainstream scheme mostly adopts mechanical pressure roller with fixed pressure or relies on manual adjustment of hydraulic / pneumatic system. Such structure cannot adjust the pre-tightening force in real time according to the thickness of the plate: when processing thick plates, the excessive pre-tightening force leads to a sharp increase in transmission resistance, which easily causes material jamming, motor overload and even scratches on the surface of the plate; while facing thin plates, insufficient pre-tightening force causes shaking and deviation in the transmission process, which directly affects the accuracy of subsequent scanning positioning. In addition, manual intervention not only reduces the continuity of production, but also takes a long time for single changeover.

[0004] In addition, the environmental adaptability of the existing scanning system is often insufficient. The existing scanning components generally adopt a single light source (such as a top direct light) and a fixed angle scanner, which exposes obvious defects in complex working conditions: for curved, high-reflective or dark plates, a single light source is easy to form local shadows or light spots, resulting in loss of barcode information; the fixed scanning angle cannot cover the side or inclined label, which needs manual secondary scanning; at the same time, environmental light interference (such as workshop lighting) further aggravates signal noise.

[0005] Therefore, it is necessary to provide an automatic feeding and scanning pipeline with dynamic adjustment function to solve the above problems. SUMMARY

[0006] To solve the above problems, the present application provides the following technical scheme: an automatic feeding and scanning pipeline with dynamic adjustment function, comprising feeding assembly and discharging assembly connected in sequence, wherein the upper part of the discharging assembly is sequentially provided with a dynamic adjustment assembly and a scanning assembly, wherein the dynamic adjustment assembly cooperates with the discharging assembly and adjusts the pre-tightening force on the material body according to the thickness of the incoming material; the dynamic adjustment assembly comprises: a dynamic adjustment seat located above the discharging assembly; a first cylinder fixed on the dynamic adjustment seat; a first rod body slidably penetrating one end of the first cylinder, and the bottom of the first rod body is connected with a first compression roller through a pre-tightening adjustment assembly; a shape-changing liquid filled in the first cylinder; and a temperature control tube arranged in the first cylinder.

[0008] As preferred, a space below the piston in the second cylinder is filled with a fluid, the fluid is connected with the pre-tightening adjusting assembly through a pipeline, and the pre-tightening adjusting assembly is used for adjusting the pre-tightening force.

[0009] As preferred, the pre-tightening adjusting assembly comprises a pre-tightening cylinder fixed below the first rod body, a connecting rod slidably penetrating one end of the pre-tightening cylinder and rotatably connected with the first compression roller, an adjusting plug fixed at the top of the connecting rod, a second spring sleeved outside the connecting rod and located between the adjusting plug and the inner bottom of the pre-tightening cylinder, a righting seat arranged in the pre-tightening cylinder and used for righting the connecting rod, and the pipeline is communicated to the pre-tightening cylinder and located above the adjusting plug.

[0010] As preferred, the code scanning assembly comprises a support fixed to one side of the discharging assembly, a first code scanner vertically arranged on the support and provided with a ring lamp at the bottom, an adjusting seat fixed to the support and located at one side of the ring lamp, a second code scanner rotatably arranged on the adjusting seat and located above the ring lamp.

[0013] As preferred, the outer surface of the guide roller is provided with a polishing layer.

[0014] Compared with the prior art, the automatic feeding and code scanning assembly pipeline with dynamic adjustment function has the following beneficial effects:

[0015] The present application realizes real-time matching of pre-tightening force and plate thickness through two-stage control of phase change locking and fluid pressure fine adjustment. The automatic pre-tightening force of thick plate is reduced to reduce the transmission resistance, and the pre-tightening force of thin plate is increased to suppress shaking. The mechanism does not require manual intervention, reduces downtime and machine adjustment time, and significantly improves the continuity of the assembly line.

DETAILED DESCRIPTION

[0024] The terms "first", "second", and the like in the description and in the claims of the present application and the above summary of the drawings are used to distinguish similar objects and are not necessarily used to describe a particular sequential or chronological order. It should be understood that the terms so used are interchangeable under appropriate circumstances and are merely employed to distinguish one embodiment of the present application from another embodiment of the present application in respect of the objects described in the description. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusions, so that a process, method, system, product, or apparatus that includes a series of elements includes not only those elements but also other elements not clearly listed or inherent to those processes, methods, products, or apparatuses.

[0025] Embodiment: In the embodiment of the present application, please refer to Figures 1-5 , an automatic feeding and scanning code pipeline with dynamic adjustment function is provided, which comprises feeding assembly 1 and discharging assembly 3 connected in turn, wherein the upper part of the discharging assembly 3 is provided with dynamic adjustment assembly 2 and scanning code assembly 4 in turn, wherein the dynamic adjustment assembly 2 cooperates with the discharging assembly 3 and adjusts the pre-tightening force on the material body according to the thickness of the incoming material.

[0026] In the implementation, the material body (plate) first enters the feeding assembly 1 and then is transmitted to the discharging assembly 3 for subsequent processing. Above the discharging assembly 3, the dynamic adjustment assembly 2 and the scanning code assembly 4 are arranged in turn to form a continuous work flow.

[0027] The core function of the dynamic adjustment assembly 2 is to perceive the thickness of the incoming material in real time and adjust the pre-tightening force on the material body accordingly.

[0028] The pre-tightening force refers to the pressure applied on the material body, which is used to ensure that the material body remains stable during transmission and avoids sliding or deviation. Subsequently, the material body enters the scanning code assembly 4 area for bar code or two-dimensional code scanning to complete information collection.

[0029] The principle of pre-tightening force adjustment is that for thicker plates, the pre-tightening force is correspondingly reduced to reduce the transmission resistance; for thinner plates, the pre-tightening force is correspondingly increased to suppress transmission shaking and ensure scanning accuracy.

[0030] The dynamic adjustment assembly 2 does not require manual intervention and can adapt to different specifications of plates, reducing downtime frequency and improving production continuity.

[0031] Specifically, the dynamic adjustment assembly 2 comprises: a dynamic adjustment seat located above the discharging assembly 3; a first cylinder body 21 fixed to the dynamic adjustment seat; a first rod body 24 slidably penetrating one end of the first cylinder body 21, and the bottom of the first rod body 24 is connected with a first compression roller 26 through a pre-tightening adjustment assembly 25; a shape-changing liquid 23 filled in the first cylinder body 21; and a temperature control pipe 22 arranged in the first cylinder body 21.

[0032] The adaptive adjustment process is as follows: initial stage: before processing a new batch of plates, the temperature control tube 22 is powered to heat the deformation liquid 23 to a liquid state, at which time the first rod 24 can freely slide in the first cylinder 21 without special resistance; positioning stage: when the plates are transported to below the first compression roller 26, the temperature control tube 22 stops heating and starts cooling, the deformation liquid 23 quickly solidifies into a solid state, locking the position of the first rod 24, so that the first compression roller 26 naturally adheres to the upper surface of the plate.

[0033] The deformation liquid 23 is a low-melting-point alloy (such as a bismuth-based or tin-based alloy), with a phase transition temperature range of 60-100°C. At room temperature, it is in a solid state, and when heated above the phase transition temperature, it changes to a liquid state, and after cooling, it returns to a solid state, with a volume shrinkage rate of ≤3%.

[0034] The first cylinder 21 is also provided with a second cylinder 27 on one side, and a second rod 28 that penetrates one end of the second cylinder 27 is slidably arranged in the second cylinder 27, the bottom of the second rod 28 is rotatably provided with a second compression roller 29, and the top of the second rod 28 is provided with a piston.

[0035] In addition, the space below the piston in the second cylinder 27 is filled with a fluid, which is connected to the pre-tightening adjustment assembly 25 through a pipeline 210, for adjusting the pre-tightening force of the pre-tightening adjustment assembly 25.

[0036] The working principle of the dynamic adjustment assembly 2 is based on temperature control phase transition and fluid pressure adjustment, realizing adaptive adjustment of the pre-tightening force.

[0037] The specific process is as follows: when processing a new batch of plates, the temperature control tube 22 is started to heat, causing the deformation liquid 23 in the first cylinder 21 to change from a solid state to a liquid state. At this time, the first rod 24 and the first compression roller 26 can freely slide, allowing the plates to be smoothly transported to below the first compression roller 26. Once the plates are in place, the temperature control tube 22 switches to a cooling mode, causing the deformation liquid 23 to cool below the phase transition temperature and solidify into a solid state, thereby locking the positions of the first rod 24 and the first compression roller 26.

[0038] The specific size of the pre-tightening force is then fine-tuned by the second cylinder 27 and the fluid; the fluid below the piston in the second cylinder 27 is connected to the pre-tightening adjustment assembly 25 through the pipeline 210, and when the fluid pressure changes, the pre-tightening adjustment assembly 25 responds to adjust, changing the compression force of the first compression roller 26 on the plates.

[0039] For example, when the thickness of the plates increases, the second rod 28 rises, some of the fluid in the pre-tightening adjustment assembly 25 is drawn out, and the pre-tightening force decreases to reduce the transportation resistance; for thin plates, the second rod 28 descends, some of the fluid in the pre-tightening adjustment assembly 25 increases, and the pre-tightening force increases to suppress the shaking.

[0040] The fluid can be a gas; in addition, the pre-tightening adjusting assembly 25 comprises: a pre-tightening cylinder 251 fixed below the first rod 24; a connecting rod 253 slidably penetrating one end of the pre-tightening cylinder 251 and rotatably connected with the first pressing roller 26; an adjusting plug 252 fixed on the top of the connecting rod 253; a second spring 254 sleeved outside the connecting rod 253 and located between the adjusting plug 252 and the inner bottom of the pre-tightening cylinder 251; a centralizing seat 255 for centralizing the connecting rod 253 is arranged in the pre-tightening cylinder 251; and the pipeline 210 is connected to the pre-tightening cylinder 251 and located above the adjusting plug 252.

[0041] When thick plates are transported, the second rod 28 in the second cylinder 27 rises, the space below the piston increases, and part of the fluid in the pre-tightening cylinder 251 is drawn back to the second cylinder 27 through the pipeline 210. The fluid pressure in the pre-tightening cylinder 251 decreases, the downward pushing force on the adjusting plug 252 decreases, and under the restoring action of the second spring 254, the connecting rod 253 drives the first pressing roller 26 to move upwards, thereby reducing the pre-tightening force on the plates and reducing the transportation resistance.

[0042] When thin plates are transported, the second rod 28 in the second cylinder 27 descends, the piston compresses the fluid below, and the fluid is pressed into the pre-tightening cylinder 251 through the pipeline 210. The fluid pressure in the pre-tightening cylinder 251 increases, pushing the adjusting plug 252 to overcome the elastic force of the second spring 254, driving the connecting rod 253 and the first pressing roller 26 to move downwards, thereby increasing the pre-tightening force on the plates and suppressing the transportation shaking.

[0043] In order to improve the smoothness of driving, a weight block is embedded in the piston.

[0044] That is, through the displacement of the piston in the second cylinder 27 and the transmission of fluid pressure, the real-time matching of the pre-tightening force and the plate thickness is realized. The pre-tightening force is automatically reduced for thick plates, and the pre-tightening force is automatically increased for thin plates, without manual intervention, significantly improving the compatibility of the assembly line for plates of different thicknesses.

[0045] In addition, the first pressing roller 26 and the second pressing roller 29 form double-point dynamic support, effectively suppressing the vibration or deviation of the plates during transportation, ensuring that the plates enter the code scanning area smoothly, and improving the code scanning efficiency.

[0046] In the embodiment, the code scanning component 4 comprises: a support 41 fixed to one side of the blanking component 3; a first code scanner 42 vertically arranged on the support 41, and the bottom of the first code scanner 42 is provided with a ring light 43; an adjusting seat 44 fixed to the support 41 and located at one side of the ring light 43, and the adjusting seat 44 is rotatably provided with a second code scanner 45; and the second code scanner 45 is located above the ring light 43.

[0047] The first code scanner 42 is vertically fixed to the support 41, the bottom ring light 43 provides 360° uniform ring illumination, eliminates environmental light interference and board surface shadow, and ensures that the bar code / QR code can be clearly identified when on the top surface.

[0048] The second code scanner 45 is angle-adjustable through the adjusting seat 44 and is located above the ring light 43, so as to supplement scanning for the side surface, curved surface or inclined surface of the board.

[0049] When the board is transmitted to the code scanning area, the code scanner is automatically selected according to the preset condition.

[0050] In addition, the two code scanners can work in parallel, for example, the first code scanner 42 scans the top surface bar code at the same time, and the second code scanner 45 synchronously scans the side surface additional label, so as to improve the information acquisition amount of single transmission.

[0051] Further, the support 41 is further fixed with a base 46, the base 46 is rotatably provided with a lead screw 47, the lead screw 47 has a bidirectional screw thread, and is respectively drivingly connected with a sliding seat, and the sliding seat is provided with a side light 48.

[0052] When the lead screw 47 rotates, the two sliding seats move synchronously along the axis of the lead screw 47. The side light 48 is fixed on the sliding seat and moves synchronously with the sliding seat to realize position adjustment. The side light 48 and the ring light 43 form a three-dimensional supplementary lighting system to ensure that the first code scanner 42 and the second code scanner 45 have no blind area identification.

[0053] In the embodiment, the feeding component 1 comprises: a feeding seat 11, on which a conveying belt 12 is arranged; two symmetrical angle plates 16, one side of the angle plate 16 is provided with a vertical rod 13 fixed to the feeding seat 11; a sliding rod 14 slidably arranged on the vertical rod 13, the sliding rod 14 is further connected with the angle plate 16, and the sliding rod 14 is further sleeved with a first spring 15 located between the vertical rod 13 and the angle plate 16; and a plurality of guide rollers 17 rotatably arranged at the bottom of the angle plate 16. The outer surface of the guide roller 17 is provided with a polishing layer.

[0054] The symmetrically arranged corner plates 16 form a sliding pair with the vertical rod 13 through the slide rod 14, and the first spring 15 is sleeved on the slide rod 14 and is pre-tightened and compressed. When the plate enters the conveying belt 12, the plate side wall pushes the guide roller 17, so that the corner plate 16 drives the slide rod 14 to slide outward along the vertical rod 13, and the first spring 15 is further compressed. The compression reaction force of the first spring 15 is transmitted to the guide roller 17 through the corner plate 16, and an elastic pushing force inward is continuously applied to the plate. Due to the symmetric arrangement of the two corner plates 16, a bidirectional elastic clamping is formed, so that the plate is forced to be automatically centered and conveyed.

[0055] The guide roller 17 is rotationally connected with the corner plate 16, converts the sliding friction of the plate and the guide structure into rolling friction, and significantly reduces the conveying resistance. The polishing layer (such as a polyurethane coating) can increase the friction coefficient of the roller surface, prevent the plate from slipping, and avoid scratching the plate surface by rigid contact.

[0056] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
