DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] In the description of the present invention, "a number" refers to one or more than one, and "a plurality" refers to two or more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] It should be noted that the operation of the punching machine and the stamping die cannot be separated from the use of lubricating oil and related maintenance oil. This will cause an oil layer on the PET film on the surface of the steel sheet, which will bring quality risks to the subsequent bonding process. At the same time, increasing manpower to remove oil stains on the surface of the PET film will also cause unstable factors, resulting in unstable quality.

[0025] Among them, the oil layer attached to the PET film on the surface of the steel sheet is not uniform, there are some positions where the oil layer is thick, and some positions where the oil layer is basically absent, the oil layer is liquid, and the oil layer has strong adhesion, and it is not easy to clean. In the related art, a non-woven fabric that is transported in the same direction as the conveying direction is used to clean the PET film on the surface of the steel sheet, wherein a roller can be set on the side of the non-woven fabric away from the surface of the steel sheet, and the non-woven fabric is pressed against the surface of the PET film by the roller, and the roller can be passively rotated to adapt to the movement of the non-woven fabric. When the steel sheet passes through the non-woven fabric, the oil layer is squeezed by the roller and the adhesion of the non-woven fabric, and is cleaned by the non-woven fabric, but it is difficult for the non-woven fabric to completely absorb and clean the locally thicker oil layer. At the same time, when the oil layer is directly squeezed by the roller, due to the adhesion of the oil layer itself, the oil layer is not easy to spread, but is compressed, but after leaving the roller, the compressed oil layer will bounce back again, resulting in the PET film surface still having an oil layer, which is difficult to completely clean.

[0026] Based on this, refer to Figures 1 to 6As shown, a cleaning device 1000 according to an embodiment of the first aspect of the present invention comprises: a base frame 100, a conveyor line 200, a telescopic assembly 300, an eccentric assembly 400 and a first cleaning assembly 500. The conveyor line 200 and the telescopic assembly 300 are directly arranged on the base frame 100. The conveyor line 200 is used to convey a workpiece 210 to be cleaned. The workpiece 210 has a cleaning surface, and the cleaning surface has an oil layer. The eccentric assembly 400 and the first cleaning assembly 500 are connected to the telescopic assembly 300 so as to perform a telescopic movement through the telescopic assembly 300, so as to enable the first cleaning assembly 500 to abut against the cleaning surface to clean the oil layer on the cleaning surface. Moreover, the first cleaning assembly 500 is transmission-connected to the eccentric assembly 400. When the first cleaning assembly 500 abuts against the cleaning surface, it can swing eccentrically driven by the eccentric assembly 400, and spread the oil layer on the cleaning surface evenly, and then be cleaned by the first cleaning assembly 500 after being spread evenly. Among them, eccentric swing is a composite motion of rotational motion and linear reciprocating motion. The oil layer will be subjected to thrusts in multiple directions, and the direction of the thrusts is constantly deformed. The thrusts received by the oil layer are diverse and changeable. The oil layer is easier to be spread and dispersed, and is not easily squeezed and compressed. The oil layer can be spread more evenly, so as to completely remove the oil layer on the clean surface.

[0027] In this embodiment, the base frame 100 includes a first support frame 110 and a second support frame 120. The first support frame 110 is erected on the ground, and the conveyor line 200 is arranged on the first support frame 110 and is lifted by the first support frame 110 so that the operator can check the conveying status of the conveyor line 200 in time. The second support frame 120 is separately connected to the top surface of the first support frame 110 to lift the telescopic assembly 300, so that the telescopic assembly 300 and the eccentric assembly 400 and the first cleaning assembly 500 connected to the telescopic assembly 300 are all located above the conveyor line 200, that is, above the workpiece 210, so as to facilitate the cleaning of the cleaning surface on the top of the workpiece 210.

[0028] As another embodiment, the conveyor line 200 and the telescopic assembly 300 may be respectively connected to different positions of the base frame 100, and the telescopic assembly 300 is located above the conveyor line 200, and the eccentric assembly 400 and the first cleaning assembly 500 are both located above the conveyor line 200.

[0029] The conveyor line 200 is arranged on the base frame 100. The conveyor line 200 can fix and convey the workpiece 210 with a clean surface. The workpiece 210 is directly fixed by the conveyor line 200, and then the fixed workpiece 210 is conveyed. When the workpiece 210 passes through the first cleaning component 500, the workpiece 210 itself can remain still and will not be displaced by the first cleaning component 500, which is more conducive to the first cleaning component 500 to evenly spread the oil layer on the clean surface.

[0030] Specifically, the conveyor line 200 can fix the workpiece 210 by vacuum adsorption, or can automatically clamp and fix the workpiece 210 by a separate fixture. In addition, because the workpiece 210 is fixed by the conveyor line 200, the workpiece 210 can overcome the influence of gravity. In theory, the conveyor line 200 can transport the workpiece 210 upside down, or transport the workpiece 210 perpendicular to the ground. The position of the telescopic component 300 is self-adapted to the position of the workpiece 210. For example, when the workpiece 210 is inverted, the telescopic component 300 is arranged under the conveyor line 200 and opposite to the bottom surface of the workpiece 210.

[0031] The telescopic assembly 300 is arranged on the base frame 100, and has a telescopic portion 310 facing the cleaning surface and capable of moving relative to the cleaning surface. The telescopic portion 310 has a first position and a second position, wherein the telescopic assembly 300 is configured as follows: in the first position, the first cleaning assembly 500 is spaced from the cleaning surface; in the second position, the first cleaning assembly 500 abuts against and cleans the cleaning surface. By controlling the relative position of the first cleaning assembly 500 and the workpiece 210 through the telescopic movement of the telescopic assembly 300, it is convenient to control the abutment force applied by the first cleaning assembly 500 to the workpiece 210, and it can also adapt to workpieces 210 of different thicknesses. In addition, the spacing between the first cleaning assembly 500 and the workpiece 210 forms a maintenance space, which is convenient for maintenance during shutdown.

[0032] Specifically, the telescopic assembly 300 can be a conventional device or mechanical structure with a telescopic function, such as an electric telescopic rod, a hydraulic telescopic rod, a screw slider telescopic structure, a crank slider telescopic structure, etc.

[0033] The eccentric assembly 400 is connected to the telescopic part 310, and moves relative to the conveyor line 200 under the drive of the telescopic part 310. When the telescopic part 310 is in the second position, the eccentric assembly 400 can work. The eccentric assembly 400 includes a driving shaft 410 facing the cleaning surface and an eccentric piece 420 connected to the driving shaft 410.

[0034] The eccentric member 420 refers to an object capable of driving the first cleaning assembly 500 to move eccentrically, such as an eccentric shaft, an eccentric wheel, a cam, etc.

[0035] The first cleaning component 500 is connected to the telescopic part 310 and can move relative to the telescopic part 310 in a first plane parallel to the cleaning surface. The first cleaning component 500 is used to clean the cleaning surface. The first cleaning component 500 is transmission-connected to the eccentric piece 420, and the eccentric piece 420 can drive the first cleaning component 500 to swing eccentrically. The first cleaning component 500 is also configured as follows: when the telescopic component 300 is in the second position, the driving shaft 410 drives the eccentric piece 420 to rotate, and at least a part of the first cleaning component 500 swings eccentrically in the first plane.

[0036] Specifically, the first cleaning component 500 is connected to the telescopic part 310, but is not relatively fixedly connected. The first cleaning component 500 can move relative to the telescopic part 310, so the connection method between the first cleaning component 500 and the telescopic part 310 tends to be a flexible connection, or other connection methods that can provide a moving space. For example, the first cleaning component 500 and the telescopic part 310 are connected by a flexible rope or a deformable elastic member, so that at least a part of the first cleaning component 500 can swing eccentrically in the first plane driven by the eccentric member 420, so that the first cleaning component 500 contacts the cleaning surface in an eccentric swinging manner, and smears and cleans the oil layer on the cleaning surface, so that the oil layer on the cleaning surface can be thoroughly cleaned, the cleaning is more thorough, the cleaning efficiency is higher, and the yield rate of the process can also be improved.

[0037] It is worth understanding that the telescopic portion 310 of the telescopic assembly 300 brings the first cleaning assembly 500 into contact with the cleaning surface of the workpiece 210. Driven by the eccentric member 420, the first cleaning assembly 500 thins the oil layer on the cleaning surface in an eccentric swinging manner. The thinned oil layer will be easier to be cleaned by the first cleaning assembly 500, so that the first cleaning assembly 500 can clean the oil layer more thoroughly, and can efficiently and thoroughly remove oil stains on the cleaning surface, thereby improving the cleaning efficiency and the process yield.

[0038] Reference Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the first cleaning assembly 500 includes: an abutment member 510 , a cleaning area 520 and a cleaning belt 530 .

[0039] In this embodiment, the abutment 510 is transmission-connected to the eccentric member 420, and the abutment 510 can swing eccentrically under the drive of the eccentric member 420; the cleaning area 520 is arranged between the abutment 510 and the cleaning surface, and when the conveyor line 200 conveys the workpiece 210, the workpiece 210 will pass through the cleaning area 520, and will be abutted by the abutment 510 in the cleaning area 520, and the oil layer on the cleaning surface will be cleaned by the cleaning belt 530; the cleaning belt 530 is partially located in the cleaning area 520 and is used to clean the cleaning surface, and the cleaning belt 530 is partially located in the cleaning area 520, and the cleaning surface of the workpiece 210 is cleaned by the cleaning belt 530 in the cleaning area 520. Among them, the first cleaning component 500 is configured as follows: when the telescopic component 300 is located in the second position, the abutment 510 abuts the cleaning belt 530 against the cleaning surface, the abutment 510 swings eccentrically in the first plane, and the cleaning belt 530 cleans the cleaning surface; It is worth understanding that the cleaning belt 530 in the cleaning area 520 is abutted against the cleaning surface by the abutment member 510, and the abutment member 510 is eccentrically swung through the eccentric member 420, so that the oil layer on the cleaning surface is evenly spread by the abutment member 510. At the same time, the cleaning belt 530 cleans the oil layer on the cleaning surface. After the oil layer is evenly spread, the oil layer on the cleaning surface is evenly distributed, and the cleaning belt 530 has a better cleaning effect on the oil layer.

[0040] As another embodiment, the first cleaning component 500 includes a cleaning roller, which is transmission-connected to the eccentric member 420, and is used to abut and clean the cleaning surface; wherein the first cleaning component 500 is configured as follows: when the telescopic component 300 is in the second position, the cleaning roller abuts and cleans the cleaning surface, and the cleaning roller swings eccentrically within the first plane.

[0041] It is worth understanding that the outer peripheral surface of the cleaning roller directly cleans the oil layer on the cleaning surface, and the cleaning roller itself swings eccentrically relative to the telescopic portion 310, so that the cleaning roller spreads the oil layer evenly while cleaning it, thereby improving the cleaning effect and the subsequent process yield.

[0042] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some specific embodiments of the present invention, the first cleaning component 500 also includes a first roller 540, a first belt roll 550 arranged on the first roller 540, and a second roller 560, the first belt roll 550 is unwound to form a cleaning belt 530, and the second roller 560 is rolled up to form a second belt roll 570; wherein, the conveying direction of the cleaning belt 530 is the same as the conveying direction of the conveyor line 200.

[0043] It is worth understanding that the tension of the cleaning belt 530 is controlled by unwinding the first roller 540 and winding the second roller 560, and the cleaning belt 530 is kept moving, so that the cleaning belt 530 contaminated by the oil layer is wound up, and the cleaning belt 530 not contaminated by the oil layer can continue to clean the workpiece 210 transported on the conveyor line 200.

[0044] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, the eccentric member 420 includes an eccentric shaft, which is eccentrically arranged on the end surface of the driving shaft 410 along the first axial direction of the driving shaft 410 and is drivingly connected to the first cleaning assembly 500.

[0045] In this embodiment, the first cleaning component 500 also includes a cleaning substrate 580, the top surface of the cleaning substrate 580 is connected to the telescopic part 310, and can move relative to the telescopic part 310 within the first plane. The cleaning substrate 580 is slidably connected between the eccentric shaft through a bearing, wherein the bearing is fixed by the cleaning substrate 580 on both sides along the axial direction of the eccentric shaft, so that the cleaning substrate 580 and the bearing can be regarded as one. At the same time, the inner ring of the bearing is fixedly connected to the eccentric shaft, so that the cleaning substrate 580 does not rotate with the rotation of the eccentric shaft, but eccentrically swings due to the thrust of the eccentric movement of the eccentric shaft. When the cleaning substrate 580, the bearing, and the eccentric shaft are assembled, the cleaning substrate 580 can swing eccentrically within the first plane, and basically does not move along the axial direction of the eccentric shaft.

[0046] As other embodiments, the eccentric member 420 includes an eccentric wheel, which is eccentrically connected to the drive shaft 410 and is transmission-connected to the first cleaning assembly 500. The eccentric wheel is sleeved on the outer peripheral surface of the drive shaft 410, or is directly connected to one end of the drive shaft 410, and the eccentric wheel and the cleaning substrate 580 can also be connected through a bearing.

[0047] Alternatively, the eccentric member 420 includes a cam, which is connected to the drive shaft 410 and is transmission-connected to the first cleaning assembly 500. The cam is sleeved on the outer circumference of the drive shaft 410, or is directly connected to one end of the drive shaft 410. The cleaning substrate 580 has a drive hole, and the cam is arranged in the drive hole. The outer circumference of the cam is in sliding contact with the inner circumference of the drive hole. As the cam rotates, the cleaning substrate 580 is thrust by the cam to swing eccentrically.

[0048] In addition, the abutment member 510 may be a passive roller, which is disposed on the bottom surface of the cleaning substrate 580 and directly abuts against the cleaning belt 530. When the cleaning belt 530 moves in a predetermined direction, the passive roller passively rotates to assist the movement of the cleaning belt 530. The passive roller is a roller that passively rotates when subjected to an external force; there may be multiple passive rollers, and in this embodiment, there are three passive rollers.

[0049] In this embodiment, the telescopic assembly 300 also includes a telescopic placement plate 320, a telescopic source 330 disposed on the telescopic placement plate 320, and a telescopic portion 310 disposed at the telescopic end of the telescopic source 330. The telescopic placement plate 320 is fixed to the base frame 100, and the telescopic portion 310 is a telescopic plate. The telescopic plate and the telescopic placement plate 320 are guided by a guide shaft. The eccentric assembly 400 is disposed on the telescopic plate to telescope along with the telescopic plate. The eccentric assembly 400 includes a motor 430, which is fixed to the telescopic plate. If the volume and telescopic distance are considered, a driving plate 340 may also be disposed between the telescopic placement plate 320 and the telescopic plate, and the motor 430 is fixed to the driving plate 340. The telescopic end of the telescopic source 330 is fixed to the driving plate 340. The motor 430 has a driving shaft 410 to drive the eccentric member 420 to rotate. The driving shaft 410 and the eccentric member 420 can be indirectly connected through a coupling 440 and a rotating shaft 450. The eccentric member 420 is arranged on the rotating shaft 450 to facilitate the installation of the eccentric member 420.

[0050] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, the drive shaft 410 has a first axis, the eccentric shaft or the eccentric wheel has a second axis, the distance between the first axis and the second axis is L, and the cleaning device 1000 satisfies: 3mm≤L≤10mm; or, the cam has a third axis and a maximum diameter with the longest length and a minimum diameter with the smallest length taking the third axis as the endpoint, the difference between the maximum diameter and the minimum diameter is X, and the cleaning device 1000 satisfies: 3mm≤X≤10mm.

[0051] It should be noted that the distance between the first axis and the second axis, and the size of the maximum and minimum diameters of the cam will directly affect the swing range of the eccentric swing of the first cleaning component 500. In this embodiment, the swing range of the eccentric swing of the first cleaning component 500 is more preferably between 3 mm and 10 mm.

[0052] Reference Figure 1 , Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, the cleaning device 1000 further includes: an elastic connector 600, one end of the elastic connector 600 is connected to the telescopic portion 310, and the other end is connected to the first cleaning assembly 500, and the elastic connector 600 can be elastically deformed so that the first cleaning assembly 500 can swing eccentrically in the first plane relative to the telescopic portion 310. It should be noted that the elastic connector 600 is in an undeformed state in the drawings, and its actual state in the drawings should be a deformed state, which is not shown in the drawings.

[0053] It is worth understanding that the deformation of the elastic connecting member 600 absorbs the deformation of the first cleaning component 500 when it eccentrically swings relative to the telescopic part 310 in the first plane, so that the first cleaning component 500 and the telescopic part 310 can remain connected, and at the same time the first cleaning component 500 can move within the first plane relative to the telescopic part 310.

[0054] In this embodiment, one end of the elastic member is connected to a side of the telescopic plate away from the telescopic placement plate 320 , and the other end is connected to the cleaning substrate 580 .

[0055] Reference Figure 5 As shown, in some specific embodiments of the present invention, the conveyor line 200 includes a conveying surface 220 for conveying the workpiece 210 and vacuum adsorption holes 221 provided on the conveying surface 220 , and the vacuum adsorption holes 221 are used to adsorb and fix the workpiece 210 on the conveying surface 220 .

[0056] In this embodiment, the conveyor line 200 adsorbs and fixes the workpiece 210 through the vacuum adsorption holes 221 of the conveying surface 220, so as to facilitate fixation of the workpiece 210 when it passes through the cleaning area 520 to ensure the cleaning effect of the workpiece 210. The workpiece 210 is not easily deviated by the eccentric swing of the first cleaning component 500.

[0057] Reference Figure 6 As shown, in some specific embodiments of the present invention, the cleaning device 1000 further includes: at least two first cleaning components 500 , and all the first cleaning components 500 are arranged in sequence along the conveying direction of the conveying line 200 .

[0058] It should be noted that when the oil layer remaining on the clean surface of the workpiece 210 is large and exceeds the cleaning capacity of the cleaning belt 530 in the cleaning area 520 , the clean surface of the workpiece 210 will still have oil layer remaining after passing through the first first cleaning assembly 500 .

[0059] Therefore, in this embodiment, a plurality of first cleaning components 500 are provided to clean the oil layer on the cleaning surface of the workpiece 210 , thereby further improving the cleaning effect of the cleaning surface of the workpiece 210 .

[0060] Reference Figure 6 As shown, in some specific embodiments of the present invention, the cleaning device 1000 also includes: a first cleaning component 500...an Nth cleaning component, N ≥ 2 and is a positive integer, the first cleaning component 500...an Nth cleaning component is arranged in sequence along the conveying direction of the conveyor line 200, and the Nth cleaning component is used to clean the workpiece 210 after passing through the first cleaning component 500.

[0061] In this embodiment, the first cleaning component 500 may only play the role of spreading the oil layer on the cleaning surface, and then the oil layer on the cleaning surface is cleaned by the Nth cleaning component; or the first cleaning component 500 may play the role of both spreading the oil layer and cleaning the oil layer. The first cleaning component 500 spreads the oil layer evenly and cleans it for the first time, and the Nth cleaning component cleans the cleaning surface a second or multiple times to remove the oil layer on the surface of the workpiece 210 as thoroughly as possible, thereby improving the cleaning effect of the cleaning device 1000 and the yield rate of subsequent processes.

[0062] Reference Figure 6 As shown, in some specific embodiments of the present invention, the production line according to the second aspect of the present invention comprises: a stamping device 2000 and a cleaning device 1000 of the first aspect, wherein the stamping device 2000 is used for stamping a workpiece 210; wherein the stamping device 2000 and the cleaning device 1000 are arranged in sequence along the conveying direction of the conveyor line 200.

[0063] It should be noted that the stamping device 2000 is very efficient in producing the workpiece 210, while the efficiency of the previous automated cleaning of the oil layer on the surface of the workpiece 210 is relatively low, so that the rate at which the stamping device 2000 produces the workpiece 210 does not match the efficiency of the cleaning device 1000 in cleaning the workpiece 210. It is difficult to directly connect the two to form an automated production line, which reduces the efficiency of the production of the workpiece 210.

[0064] In this embodiment, the cleaning device 1000 in the first aspect of the embodiment greatly improves the cleaning efficiency of the workpiece 210, so that the cleaning efficiency of the cleaning device 1000 can match the efficiency of the punching device 2000 in punching the workpiece 210, and the two can be assembled to form an automated production line to achieve automated production of the workpiece 210, greatly improving the production efficiency of the workpiece 210. At the same time, the cleaning device 1000 in the first aspect of the embodiment can efficiently and thoroughly remove oil stains on the clean surface of the workpiece 210, improve the cleaning efficiency and improve the process yield.

[0065] Specifically, the punching device 2000 has a punching conveyor, which is used to convey the workpiece 210 before punching to the punching position and convey the workpiece 210 after punching, and the punching conveyor is connected to the conveyor line 200 to transfer the workpiece 210 after punching to the conveyor line 200. As another embodiment, the conveyor line 200 can pass through both the punching device 2000 and the first cleaning assembly 500.

[0066] Reference Figure 6 As shown, in some specific embodiments of the present invention, the production line further includes: a material unloading device 3000, which is arranged behind the cleaning device 1000 along the conveying direction, and the material unloading device 3000 is used to collect the cleaned workpieces 210.

[0067] In this embodiment, the unloading device 3000 includes a unloading track 3100 and a plurality of collecting pieces 3200 arranged on the unloading track 3100. The unloading direction of the unloading track 3100 is perpendicular to the conveying direction of the conveyor line 200. The plurality of collecting pieces 3200 are arranged in sequence along the conveying direction of the unloading track 3100. The unloading track 3100 can drive the collecting pieces 3200 to move in sequence along the unloading direction, so that the collecting ports of different collecting pieces 3200 are aligned with the end of the conveyor line 200, thereby collecting the workpiece 210, realizing the automatic recovery of the workpiece 210, and realizing the automatic unloading of the workpiece 210.

[0068] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
