Description

Technical Field

[0001] The invention relates to the technical field of concrete pre-preparation, and specifically discloses an intelligent cleaning device for a mold platform of a PC board production line. Background Art

[0002] In the mechanized production and processing of PC boards, the solidified PC boards are lifted by a crane to separate them from the formwork, and then the formwork is transported to the next station for recycling. However, when the PC boards are separated from the formwork, not only will some debris fall on the upper surface of the formwork, but also in some local areas where the release agent has not fully exerted its effect, a part of the solidified concrete layer will firmly adhere to the upper surface of the formwork during the lifting of the PC boards. This part of the concrete layer cannot be removed from the surface of the formwork by traditional cleaning operations, and the current commonly used treatment method is to use a high-speed rotating wire brush or a scraper to forcibly remove it.

[0003] For example, the invention application with application number 201910019288X discloses a mobile formwork cleaning machine, including a mobile formwork and a frame, the frame is set in the moving direction of the mobile formwork, and also includes a wire grinder, there are multiple wire grinders, multiple wire grinders are arranged side by side on the frame, and the frame is inclined relative to the mobile formwork; it also includes a spring scraper and a dust collector, the spring scraper and the dust collector are both arranged on the truss, and the spring scraper is arranged at the front of the wire grinder. The mobile formwork cleaning machine disclosed in the above invention patent uses a scraper and a wire brush to cooperate to achieve the cleaning of the concrete silo on the surface of the formwork. Compared with manual cleaning, it improves the working efficiency. However, in the actual processing process, once the area and thickness of the concrete material remaining on the surface of the formwork are large, the scraper is often unable to shovel it due to excessive resistance in the process of forcibly shoveling it up, and then using a wire brush for processing not only fails to effectively brush it off, but also easily causes the wire brush to wear out quickly and fail, and the wire brush needs to be replaced frequently. Based on the shortcomings of traditional methods of forcibly treating the concrete layer on the surface of the formwork using a wire brush or a spatula, the present application proposes an intelligent cleaning device for the formwork of a PC board production line that can effectively solve the above technical problems. Summary of the invention

[0004] The present invention aims to provide an intelligent cleaning device for a formwork platform of a PC board production line to solve the technical problems and shortcomings of forcibly treating the concrete material layer on the surface of the formwork platform by using a traditional wire brush or a spatula.

[0005] The present invention is achieved through the following technical solutions:

[0006] An intelligent cleaning device for mold pallets of a PC board production line, comprising a mold pallet conveying unit and tracks arranged on both sides of the mold pallet conveying unit, a multi-process cleaning unit is arranged directly above the mold pallet conveying unit, and moving mechanisms traveling along the tracks are arranged on both sides of the multi-process cleaning unit, the multi-process cleaning unit comprises a cover body with an opening at the lower end, a pre-cleaning mechanism, a mold pallet information collection mechanism, a local tip crushing mechanism, a wire brush cleaning mechanism, a tail cleaning mechanism and a debris suction and filtering mechanism are arranged on the cover body in sequence, the mold pallet information collection mechanism is electrically connected to a control box, and a signal output end of the control box is connected to the local tip crushing mechanism and the wire brush cleaning mechanism;

[0007] The mold platform information acquisition mechanism includes a mounting bar fixed at the upper end of the inner cavity of the cover body, and a row of CCD cameras arranged toward the mold platform conveying unit are arranged on the mounting bar. The local tip crushing mechanism includes a transmission frame that is moved up and down by a lifting device, and an upper loading plate that is moved and arranged along a direction perpendicular to the conveying direction of the mold platform conveying unit is arranged on the transmission frame. A mounting plate is arranged below the upper loading plate, and the mounting plate is connected to the upper loading plate through a vertical sliding rod and a second spring. A tip nail plate is arranged on the lower surface of the mounting plate, and a tip crushing nail is arranged on the lower surface of the tip nail plate. An electromagnet is arranged on the upper loading plate, and a magnetic suction block aligned with the electromagnet is arranged on the mounting plate.

[0008] During the operation of the PC board production line mold table intelligent cleaning device disclosed by the present invention, the pre-cleaning mechanism first cleans the debris and dust on the mold table surface to avoid affecting the subsequent CCD camera's capture and judgment of the actual situation of the mold table surface.

[0009] After the pre-cleaning of the mold platform surface is completed, the CCD camera will take pictures of the upper surface of the mold platform, and then the control box will process and judge the pictures to generate signals for controlling the local tip crushing mechanism and the wire brush cleaning mechanism. When a concrete layer is found in a certain area on the mold platform surface, the tip nail plate is first moved to the top of it, and then the lifting device is used to move it down to a suitable height, and then the current is passed through the electromagnet to generate magnetic attraction to the magnetic block, so that the tip nail plate moves upward and compresses the second spring to accumulate potential, and finally the power is cut off instantly so that the tip nail plate moves downward quickly under the action of the spring potential energy, and the tip crushing nail instantly crushes the concrete layer, so that the concrete layer collapses from the upper surface of the mold platform, and then it can be easily and forcibly swept from the mold platform surface using a high-speed rotating wire brush.

[0010] Finally, the processed debris is cleaned by the finishing cleaning mechanism, and the debris suction and filtration mechanism performs suction and filtration to complete the cleaning of the mold table surface, while ensuring the environment of the entire workshop.

[0011] As a further configuration of the above scheme, the mold platform information acquisition mechanism also includes a laser scanning and ranging component arranged on the mounting bar, and the laser scanning and ranging component is arranged to move along a direction perpendicular to the conveying direction of the mold platform conveying unit.

[0012] As a further configuration of the above scheme, a strip-shaped opening is provided on the mounting bar, the laser scanning and ranging assembly includes a sliding seat movably arranged in the strip-shaped opening, a laser ranging module is arranged at the lower end of the sliding seat, and a second synchronous belt assembly connected to the sliding seat is arranged at the side end of the mounting bar.

[0013] The above further uses a laser scanning and ranging component to scan the concrete silo to determine the specific thickness, and then the control box can accurately control the magnitude of the current passed into the electromagnet, so that the second spring can be compressed to obtain the corresponding potential energy, ensuring that the tip crushing nail has sufficient energy to act on the concrete layer, and can also effectively avoid damage to the formwork and the tip nail plate due to excessive kinetic energy.

[0014] As a further configuration of the above scheme, the transmission frame is provided with a parallel first synchronous belt assembly and a guide slide bar, the upper loading plate is connected to the first synchronous belt assembly, and a slide hole seat interacting with the guide slide bar is provided on the upper loading plate. The above is one of the specific schemes for precise movement and positioning of the upper loading plate, using the first synchronous belt assembly as a transmission member, and then cooperating with the guide slide bar to achieve precise movement of the tip nail plate to just above the concrete material layer.

[0015] As a further configuration of the above scheme, the wire brush cleaning mechanism includes a transmission box that is moved up and down by a lifting device, a row of wire brushes is arranged below the transmission box, the upper end of the wire brush is connected to a wire brush shaft that is rotatably extended into the transmission box, the transmission box is provided with a bevel gear transmission assembly for synchronously driving all the wire brush shafts, and the side end of the transmission box is provided with a drive motor connected to the bevel gear transmission assembly. The above is one of the specific schemes of the wire brush cleaning mechanism, which can realize the synchronous operation of all wire brushes with only one drive motor, ensuring that the residual concrete layer on the surface of the formwork table is cleaned.

[0016] As a further configuration of the above scheme, the pre-cleaning mechanism includes a brush strip connected to the outer end of the cover body through a first spring and a guide column, and the lower surface of the brush strip is provided with flexible bristles. The above is one of the specific schemes of the pre-cleaning mechanism, and the supporting force of the first spring can ensure that the flexible bristles can fully clean the debris and dust on the surface of the mold platform.

[0017] As a further configuration of the above scheme, the finishing cleaning mechanism includes a cleaning roller rotatably arranged at the lower end of the side surface of the cover body, a cleaning motor is arranged at the end of the cleaning roller, and flexible bristles are arranged on the roller body of the cleaning roller, an arc-shaped material guide plate that acts on the cleaning roller is arranged at the lower end of the side surface of the cover body, and a suction port is opened above the arc-shaped material guide plate.

[0018] As a further configuration of the above scheme, the debris suction and filtering mechanism includes a suction pipe connected to the suction port, the end of the suction pipe is connected to a filter box located at the upper end of the cover body, and the other side of the filter box is connected to an air pump.

[0019] The above is a specific design scheme for the final cleaning mechanism and the debris suction and filtering mechanism. After the wire brush forcibly removes the concrete from the surface of the formwork table, the cleaning roller is used to send the debris and dust into the suction port, and then the debris suction and filtering mechanism draws them away and filters them, so that the debris and dust can finally be cleaned out from the filter box when the machine is shut down.

[0020] As a further configuration of the above solution, the tip nail plate is detachably connected to the lower surface of the mounting plate via a connecting piece. The detachable mounting design of the tip nail plate can be easily replaced after the tip nail plate is damaged.

[0021] As a further configuration of the above scheme, the moving mechanism includes a wheel seat, on which is provided a row of rollers that interact with the track, and on which is provided a travel motor for driving the rollers, and the upper end of the wheel seat is provided with a vertical connecting rod and a hydraulic cylinder connected to the cover body.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] The PC board production line formwork intelligent cleaning device disclosed in the present invention first uses a CCD camera to capture the concrete silo information on the surface of the formwork during operation, then moves the tip nail plate to above the area, and then uses the magnetic attraction effect to allow the tip nail plate to obtain sufficient spring potential energy. Under the action of the spring potential energy, the tip nail plate can be instantly pressed down, and the tip crushing nails on the tip nail plate are used to instantly crush the concrete material layer, so that the concrete material layer is broken from the upper surface of the formwork, and finally a high-speed rotating wire brush can be used to easily and forcibly sweep it from the surface of the formwork, which effectively solves the problem that the existing shovel blade cannot shovel due to excessive resistance during the process of forcibly shoveling a large-area concrete silo, and avoids the problem that the wire brush is easily worn out too quickly and needs to be frequently replaced when forcibly processing the large-area concrete silo, thereby effectively improving the cleaning efficiency of the formwork surface and reducing the damage cost of the equipment.

[0024] The present invention further arranges a laser scanning and ranging component to cooperate with a CCD camera to detect the thickness of the concrete layer, and then uses a control box to accurately control the magnitude of the current passed into the electromagnet, so that the tip nail plate can obtain the corresponding spring potential energy, ensuring that the tip crushing nail has sufficient crushing energy for the concrete layer, and can also effectively avoid damage to the formwork table and the tip nail plate due to excessive kinetic energy, thereby effectively improving the life of the entire equipment and the formwork table.

[0025] The multi-process cleaning unit of the present invention is provided with a pre-cleaning mechanism, a mold platform information collection mechanism, a local tip crushing mechanism, a wire brush cleaning mechanism, a finishing cleaning mechanism and a debris suction and filtering mechanism in sequence. During operation, the mold platform surface can be pre-cleaned first to avoid errors in the capture of mold platform information caused by residual impurities, and then a crushing treatment is performed according to the captured information, and then a wire brushing treatment is performed. Finally, the impurities on the mold platform surface are cleaned and filtered and collected by the finishing cleaning mechanism and the debris suction and filtering mechanism, thereby realizing full-process automated processing and greatly improving the cleaning effect and efficiency of the mold platform surface.

[0040] Reference Figure 3 , Attachment Figure 4 and attached Figure 5The multi-process cleaning unit 2 includes a cover 201 with an opening at the lower end, and the two ends of the cover 201 are connected to the hydraulic cylinders 404 on the two moving mechanisms 4. At the same time, the front and rear ends of the cover 201 are provided with guide holes that match the corresponding vertical connecting rods 403. In addition, a control box 5 is also provided on the outer surface of the cover 201. The control box 5 is used to receive information feedback and control all electrical components in the multi-process cleaning unit 2.

[0041] The cover body 201 is provided with a pre-cleaning mechanism 6, a die table information collection mechanism 7, a local tip crushing mechanism 8, a wire brush cleaning mechanism 9, a final cleaning mechanism 10 and a debris suction and filtering mechanism 11 from left to right. The pre-cleaning mechanism 6 includes a brush bar 601 provided on the outside of the left side of the cover body 201, and a large number of flexible bristles are provided on the lower surface of the brush bar 601. At the same time, in order to ensure that the flexible bristles can fully and effectively interact with the upper surface of the die table, the brush bar 601 is also connected to the cover body 201 through a guide column and a first spring 602, and the support force provided by the first spring 602 can ensure that the dust and debris on the surface of the die table 100 are swept away.

[0042] The formwork information collection mechanism 7 includes a mounting bar 701 fixed on the inner wall on the left side of the cover body 201, and a plurality of CCD cameras 702 are arranged on the mounting bar 701 at equal intervals along the width direction of the formwork 100, and the CCD camera 702 is connected to the image processing module inside the control box 5 through a wire, and then the control module inside the control box 5 compares and analyzes the photographs of the formwork surface taken, determines the Y-axis coordinate position of the residual concrete layer on the surface (the X-axis is parallel to the conveying direction of the formwork), and then sends out a corresponding control signal to drive the local tip crushing mechanism 8 to operate.

[0043] Reference Figure 6 and attached Figure 7 The local tip crushing mechanism 8 includes a lifting beam 801, and a lifting device 802 connected to the lifting beam 801 is arranged on the top of the cover body 201. The lifting device 802 in this embodiment preferably uses a screw lifter, so that the lifting beam 801 can be accurately controlled to move up and down under the action of the screw lifter. A transmission frame 803 is connected to one side end of the lifting beam 801, and a first synchronous belt assembly 804 arranged along the Y axis is arranged on the side of the transmission frame 803. At the same time, a guide slide bar 805 parallel to the first synchronous belt assembly 804 is also arranged on the transmission frame 803. An upper loading plate 806 is arranged below the guide slide bar 805. The upper loading plate 806 is not only fixedly connected to the first synchronous belt through the connecting block, but also a sliding hole seat 807 that interacts with the guide slide bar 805 is fixedly arranged on the upper surface 806 of the upper loading plate, so that under the transmission of the first synchronous belt assembly 804 and the guiding action of the guide slide bar 805, the upper loading plate 806 can be accurately moved along the X-axis direction.

[0044] A mounting plate 812 is provided below the upper loading plate 806, and a vertical slide bar 808 vertically penetrating the upper loading plate 806 is provided at each of the four corners on the upper surface of the mounting plate 812, and a second spring 809 is connected between the mounting plate 812 and the upper loading plate 806. In addition, a magnetic block 810 is provided on the upper surface of the mounting plate 812, and then an electromagnet 811 is provided on the upper loading plate 806 to align with the magnetic block 810 up and down, so that when the electromagnet 811 is energized, a large magnetic attraction force can be generated on the magnetic block 810, so that the mounting plate 812 moves upward and compresses the second spring 809 to accumulate potential. Finally, a sharp nail plate 810 is detachably installed on the lower surface of the mounting plate 812 by means of screws and other connectors, and a large number of sharp breaking nails 811 are provided on the lower surface of the sharp nail plate 810.

[0045] Reference Figure 6 and attached Fig. 9 The wire brush cleaning mechanism 9 includes a transmission box 901 fixedly connected to the other side of the lifting beam 801, the transmission box 901 is arranged parallel to the guide slide bar 805, and a driving motor 902 is installed at one end of the transmission box 901, and then a driving rod 903 extending into the transmission box 901 is connected to the driving motor 902, and a plurality of first bevel gears 904 located inside the transmission box 901 are arranged at equal intervals on the driving rod 903. A plurality of wire brush shafts 905 extending into the transmission box 901 are rotatably connected to the lower surface of the transmission box 901 through bearings, and a second bevel gear 906 meshing with the corresponding first bevel gear 904 is arranged on the top of the wire brush shaft 905, and then a wire brush 907 is connected to the lower end of each wire brush shaft 905.

[0046] Reference Figure 4 and attached Figure 5 The final cleaning mechanism 10 includes a cleaning roller 101 rotatably arranged at the lower right end of the inner cavity of the cover body 201, a corresponding cleaning motor is arranged at one end of the cleaning roller 101, and a large number of flexible bristles are also arranged on the roller body of the cleaning roller 101. At the same time, an inwardly concave arc-shaped guide plate 202 is arranged at the lower right end of the cover body 201, and a suction port is opened above the arc-shaped guide plate 202, so that under the action of the cleaning roller 101, impurities on the upper surface of the mold platform 100 can be swept to the upper end of the arc-shaped guide plate 202, and then enter the suction port to be sucked away by the debris suction and filtering mechanism 11 and filtered.

[0047] The specific debris suction and filtering mechanism 11 includes a suction pipe 111 connected to the outside of the suction port, and a filter box 112 and an air pump 113 are arranged on the upper surface of the cover body 201. The end of the suction pipe 111 is connected to one end surface of the filter box 112, and then the air pump 113 is connected to the other end surface of the filter box 112. At the same time, a corresponding filter layer is arranged inside the filter box 112, so that the debris suction and filtering mechanism 11 can draw the debris impurities swept up by the final cleaning mechanism 10 into the filter box 112 for filtering and interception during operation, and finally carry out centralized cleaning.

[0048] During the operation of the PC board production line mold intelligent cleaning device disclosed in this embodiment 1, the mold conveying unit 1 conveys the mold 100 to the bottom of the mold conveying unit 1 and then stops, and then the moving mechanism 4 is started to make the multi-process cleaning unit 2 move along the length direction of the mold 100. During its movement, the flexible bristles in the pre-cleaning mechanism 6 first push away the concrete debris and dust remaining on the surface of the mold, and then the CCD camera 702 captures the surface information of the pre-cleaned mold, and feeds the captured information back to the control box 5 for online processing and judgment. When it is found that there is a concrete layer that cannot be swept away in a certain area on the surface of the mold 100, the control box 5 will generate an influential control signal to control the operation of the subsequent local tip crushing mechanism 8, so that under the action of the first synchronous belt assembly 804, the tip nail plate 810 is moved to align with the concrete layer, and then the lifting device 802 is started to push the local tip crushing mechanism 8 and the wire brush cleaning mechanism 9 downward.

[0049] When the local tip crushing mechanism 8 is in operation, current is first supplied to the electromagnet 810, so that it can generate a large magnetic attraction force on the magnetic attraction block 810, so that the mounting plate 812 moves upward and compresses the second spring 809 to accumulate potential, and then the current supplied to the electromagnet 810 is instantly disconnected, so that the tip nail plate 810 can quickly move downward under the action of the spring potential energy, and the tip crushing nail 811 quickly acts on the concrete material layer, and the concrete material layer is broken by the action of the tip crushing nail 811, reducing the resistance in the subsequent wire brush cleaning process. Then, the wire brush 907 with rotating wires in the wire brush cleaning mechanism 9 cleans this part of the concrete material layer and separates it from the upper surface of the mold platform 100.

[0050] Finally, the cleaning roller 101 in the final cleaning mechanism 10 sweeps the concrete debris separated from the formwork 100 to the arc-shaped material guide plate 202, and then the concrete debris is sucked into the filter box 112 by the suction pipe 111 for filtration and retention. Finally, after the equipment is shut down, the impurities in the filter box 112 can be centrally cleaned. Example 2

[0051] Example 2 discloses an intelligent cleaning device for molds of a PC board production line that is further optimized and improved based on Example 1. The similarities between the device and Example 1 will not be described again.

[0052] The formwork information collection mechanism 7 in this embodiment 2 is also provided with a laser scanning and ranging component on the mounting bar 701, which is movable in a direction parallel to the guide slide bar 805, so that after the CCD camera 702 captures a residual concrete layer locally on the upper surface of the formwork 100, the laser scanning and ranging component can move to the area, and then move and scan the area to obtain the thickness of the residual concrete layer, and feed back the collected information to the control box 5, and the control box 5 controls the operation of the local tip crushing mechanism 8.

[0053] For specific settings, refer to the attached Figure 8 The installation bar 701 is provided with a strip opening 703 arranged parallel to the guide slide bar 805, a sliding seat 704 is arranged in the strip opening 703, and a vertically arranged laser distance measuring module 705 is arranged on the lower surface of the sliding seat 704, and the laser distance measuring module 705 is electrically connected to the control module inside the control box 5. In addition, a second synchronous belt assembly 706 is arranged at the side end of the installation bar 701, and the sliding seat 704 is fixedly connected to the second synchronous belt assembly 706, so that the laser distance measuring module 705 can be accurately moved under the transmission action of the second synchronous belt assembly 706. In addition, a control circuit or controller for controlling the current size of the electromagnet 811 is also arranged inside the control box 5.

[0054] When the intelligent cleaning device for the mold base of the PC board production line disclosed in this embodiment 2 is in operation, the pre-cleaning mechanism 6 first cleans the dust and debris on the upper surface of the mold base, and then the CCD camera 702 captures whether there is a residual concrete layer on the upper surface of the mold base 100. When a concrete layer is found locally, the second synchronous belt assembly 706 is started to move the laser ranging module 705 above it, and then the residual concrete layer is scanned during the movement of the laser ranging module 705, and the thickness of the concrete layer is determined.

[0055] After the thickness of the concrete layer is calculated, the control box 5 controls the current passed through the electromagnet 811, so that the second spring 809 can be compressed to different lengths, thereby storing potential energy of different sizes, and then the current passed through the electromagnet 811 is disconnected. At this time, under the action of the second spring 809, the tip nail plate 810 can obtain the corresponding dynamic potential energy, and finally the tip nail plate 810 moves quickly toward and forcibly pierces the concrete layer through the tip crushing nail 811 on the lower surface, so as to facilitate the subsequent effective cleaning and removal of it by the wire brush 907. At the same time, based on the thickness of different concrete layers, the tip crushing nail 811 can obtain the corresponding crushing kinetic energy, which can not only realize the effective crushing of the concrete silo, but also avoid the tip nail plate 810 being pressed into the upper surface of the mold platform 100 when the power is too large, causing damage to the mold platform and the tip nail plate 810.

[0056] Finally, this embodiment 2 also provides a debris conveyor 12 below one end of the mold pallet conveying unit 1, and a discharge port connected to the debris conveyor 12 is opened on the mold pallet conveying unit 1, so that the debris swept by the pre-cleaning mechanism 6 can be directed out by the debris conveyor 12 to avoid residue on the mold pallet conveying unit 1 and contaminating the equipment.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
