Description

Technical Field

[0001] The present application relates to the technical field of multilayer board processing, and in particular to a board installation system. Background Art

[0002] In various production lines, it is often necessary to stack the plates transported by the conveyor line into piles before continuing to transport them to the next workstation by the conveyor line.

[0003] For example, in the multilayer board manufacturing industry, a loading system is typically used to feed the multilayer boards into a hot press for pressurization and heating. The loading system automatically feeds the multilayer boards into the press. In related technologies, groups of 15 boards are fed sequentially into the feeder via the front-end and roller feed mechanisms in the loading system for pressurization and heating, ultimately forming a composite.

[0004] In the related technology, the current plate loading system uses a suction cup to adsorb the plate on the top, and then uses multiple cylinders to push the adsorbed plate to the roller plate feeding mechanism, and then drives the plate to the next process through the roller plate feeding mechanism. However, the multiple cylinders have poor synchronization, resulting in uneven thrust on the plate, and there is a risk of plate deviation and ineffective transportation, and even damage to the suction cup, affecting work efficiency. Utility Model Content

[0005] The present application provides a plate loading system, which can effectively transport plates to the next process and has a long service life.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0007] The present application provides a plate loading system, comprising a frame, a front-end plate feeding mechanism, and a roller plate feeding mechanism, wherein the front-end plate feeding mechanism and the roller plate feeding mechanism are arranged along a first direction, the front-end plate feeding mechanism is movably arranged on the frame, the front-end plate feeding mechanism is used to absorb the plate and push the plate to the roller plate feeding mechanism along the first direction, the roller plate feeding mechanism has a plate feeding roller, and the plate feeding roller is used to drive the plate to move along the first direction to be sent to the next process;

[0008] Among them, the front-end plate feeding mechanism includes a frame, an adsorption component, a linear slide rail and a single cylinder, which can be raised and lowered on the frame. There are two linear slide rails. Along the second direction, the two sides of the adsorption component are connected to the frame through linear slide rails to slide relative to the frame along the first direction. The single cylinder is set on the frame and is used to drive the adsorption component to slide along the first direction. The adsorption component is equipped with a suction cup, which is used to adsorb the plate. The first direction and the second direction are perpendicular to each other.

[0009] Currently, the panel loading system is used to feed multi-layer panels into a hot press for pressurization and heating. For example, several panels are stacked on a rack, and the front-end panel feeding mechanism and the roller panel feeding mechanism are located above the several panels. The front-end suction cup picks up a wooden board on the top, lifts it a certain height, and pushes the panel to the panel feeding roller, which drives the panel feeding roller to feed the panel to the next mechanism. Based on the current panel loading system, the above scheme is improved by providing linear slide rails on both sides of the adsorption component to slide with the frame, and using a single cylinder to push the adsorption component to slide. This can effectively improve the stability of the adsorption component moving along the first direction, reduce the risk of structural damage caused by uneven force on the adsorption component, thereby effectively increasing the service life of the front-end panel feeding mechanism and improving the reliability of the entire panel loading system.

[0010] According to some embodiments of the present application, the adsorption assembly includes a fixing rod and a suction cup, and opposite ends of the fixing rod along the second direction are respectively connected to the frame via linear slide rails;

[0011] Along the second direction, a fixing block is provided in the middle of the fixing rod, a slot is formed in the fixing block, and a protrusion is provided at the end of the telescopic rod of the single cylinder, and the protrusion is inserted into the slot.

[0012] In the above scheme, on the one hand, by setting the connection part between the single cylinder and the fixed rod in the middle of the fixed rod, the thrust of the single cylinder can be evenly applied to the two linear slide rails, reducing the risk of damage to the linear slide rail structure; on the other hand, through the cooperation of the protrusion and the slot, the difficulty of connecting the single cylinder and the fixed rod can be reduced, and the single cylinder can be easily replaced and maintained.

[0013] According to some embodiments of the present application, the adsorption assembly includes at least two pairs of suction cups, and the at least two pairs of suction cups are spaced apart along the second direction, and each pair of suction cups includes two adjacently arranged suction cups.

[0015] According to some embodiments of the present application, the adsorption assembly includes two pairs of suction cups, and along the second direction, the two pairs of suction cups are symmetrically arranged relative to the middle portion of the fixing rod.

[0016] In the above solution, by symmetrically arranging two pairs of suction cups along the middle of the fixed rod, the adsorption force can be evenly provided to the plate, thereby reducing the risk of the plate tilting due to uneven adsorption force, resulting in uneven force applied by the plate feeding roller to the plate, resulting in the plate being unable to be effectively transported to the next process.

[0017] According to some embodiments of the present application, the roller plate feeding mechanism is disposed on a side of the frame away from the adsorption assembly along the first direction.

[0018] In the above solution, by integrating the roller plate feeding mechanism with the frame, the space utilization rate of the plate loading system can be effectively improved, so that the plate loading system has a compact structure and occupies a small area.

[0019] According to some embodiments of the present application, the roller plate feeding mechanism includes a mounting rod, a drive assembly and a plurality of plate feeding rollers, the mounting rod being connected to the frame at both ends along the second direction, the plurality of plate feeding rollers being hinged on the mounting rod, the drive assembly being connected to the frame and being used to drive the plate feeding rollers to deflect relative to the mounting rod to contact or leave the plate transported by the front end plate feeding mechanism.

[0020] According to some embodiments of the present application, the driving assembly includes a steel belt type rodless cylinder, a moving rod, an auxiliary guide mechanism and a push rod; the steel belt type rodless cylinder is arranged on the frame and is used to drive the moving rod to move along a first direction, the auxiliary guide mechanism is arranged between the moving rod and the frame, and is used to guide the moving rod to slide relative to the frame along the first direction, and the push rod is connected to the moving rod and is used to drive the feeding plate roller to deflect.

[0021] In the above scheme, compared with the current scheme of using magnetically coupled rodless cylinders in the plate loading system, the steel belt rodless cylinder is more durable, and in conjunction with the auxiliary guide mechanism, it can stably enable the moving rod to drive the push rod to move back and forth in the first direction, so as to effectively deflect the plate feeding roller, thereby effectively driving the plate to the next process.

[0022] According to some embodiments of the present application, the auxiliary guide mechanism includes a guide rod and a guide wheel. The guide wheel is rotatably disposed on the movable rod. The guide rod is fixed to the frame and extends along the first direction. The guide wheel and the guide rod are in rolling cooperation.

[0023] In the above solution, the guide rod and the guide wheel cooperate with each other in rolling manner, so that the movable rod can be stably moved along the first direction under the drive of the steel belt type rodless cylinder.

[0024] According to some embodiments of the present application, along the second direction, the steel belt type rodless cylinder is located in the middle of the moving rod.

[0025] There are two auxiliary guide mechanisms, and the two auxiliary guide mechanisms are symmetrically arranged relative to the middle part of the moving rod.

[0026] In the above solution, the steel belt type rodless cylinder is located in the middle of the moving rod, and the two auxiliary guide mechanisms are symmetrically arranged relative to the middle of the moving rod, which can make the moving rod evenly stressed and stably drive the feeding plate roller to deflect through the push rod.

[0042] See Figure 1-Figure 3 , Figure 1 Schematic diagram of the panel mounting system in some current embodiments. Figure 2 This is a structural diagram of the front-end plate feeding mechanism and the roller plate feeding mechanism in some embodiments of the present application. Figure 3 This is a top view of the front-end plate feeding mechanism and the roller plate feeding mechanism in some embodiments of the present application.

[0043] The present application provides a plate loading system 100, which includes a frame 10, a front-end plate feeding mechanism 20 and a roller plate feeding mechanism 30. The front-end plate feeding mechanism 20 and the roller plate feeding mechanism 30 are arranged along a first direction x. The front-end plate feeding mechanism 20 can be raised and lowered on the frame 10. The front-end plate feeding mechanism 20 is used to adsorb the plate 50 and push the plate 50 to the roller plate feeding mechanism 30 along the first direction x. The roller plate feeding mechanism 30 has a plate feeding roller 33. The plate feeding roller 33 is used to drive the plate 50 to move along the first direction x to be sent to the next process.

[0044] Among them, the front-end plate feeding mechanism 20 includes a frame 21, an adsorption component 22, a linear slide 23 and a single cylinder 24, which can be raised and lowered on the frame 10. There are two linear slides 23. Along the second direction y, the two sides of the adsorption component 22 are connected to the frame 21 through linear slides 23 to slide relative to the frame 21 along the first direction x. The single cylinder 24 is set on the frame 21 and is used to drive the adsorption component 22 to slide along the first direction x. The adsorption component 22 is equipped with a suction cup 221, which is used to adsorb the plate 50. The first direction x and the second direction y are perpendicular to each other.

[0045] At present, the panel loading system 100 is used to feed multi-layer panels into a hot press for pressurization and heating. For example, a number of panels 50 are stacked on a frame 10, and the front-end panel feeding mechanism 20 and the roller panel feeding mechanism 30 are located above the number of panels 50. The front-end suction cup 221 sucks up a wooden board on the top, lifts it to a certain height, and pushes the panel 50 to the panel feeding roller 33. The panel feeding roller 33 drives the wooden board to be fed into the next mechanism.

[0046] In some embodiments, a lifting mechanism 40 is provided on the frame 10, and the lifting mechanism 40 can drive the front-end plate feeding mechanism 20 to rise and fall. For example, the lifting mechanism 40 can include a gear rack linear drive device.

[0047] As in the prior art, the suction cup 221 is connected to an external negative pressure source and picks up the plate 50 (wooden board) by negative pressure adsorption. The plate feeding roller 33 provided in some embodiments of the present application has the same working principle as the plate feeding roller 33 currently on the market, and will not be described in detail in some embodiments of the present application.

[0048] Based on the improvement of the current panel loading system 100, in the above scheme, by arranging linear slide rails 23 on both sides of the adsorption component 22 to slide with the frame 21, and using a single cylinder 24 to push the adsorption component 22 to slide, the stability of the adsorption component 22 moving along the first direction x can be effectively improved, and the risk of structural damage caused by uneven force on the adsorption component 22 can be reduced, thereby effectively improving the service life of the front-end panel feeding mechanism 20 and improving the reliability of the entire panel loading system 100.

[0049] According to some embodiments of the present application, the adsorption assembly 22 includes a fixed rod 220 and a suction cup 221. The fixed rod 220 is connected to the frame 21 at opposite ends along the second direction y via linear guide rails 23. A fixed block 2200 is provided in the middle of the fixed rod 220 along the second direction y. The fixed block 2200 has a slot formed therein. The end of the telescopic rod of the single cylinder 24 is provided with a protrusion 240, which is inserted into the slot.

[0050] The linear guide rail 23 may include a track extending along the first direction x and a slider disposed on the track, the slider being capable of sliding along the track. The slider is fixed to the fixing rod 220 , and the track is fixed to the frame 21 .

[0051] In the above scheme, on the one hand, by setting the connection part between the single cylinder 24 and the fixed rod 220 in the middle of the fixed rod 220, the thrust of the single cylinder 24 can be evenly applied to the two linear slide rails 23, reducing the risk of damage to the structure of the linear slide rails 23; on the other hand, by cooperating with the protrusion 240 and the slot, the difficulty of connecting the single cylinder 24 and the fixed rod 220 can be reduced, and the single cylinder 24 can be easily replaced and maintained.

[0052] According to some embodiments of the present application, the adsorption assembly 22 includes at least two pairs of suction cups 221 , and the at least two pairs of suction cups 221 are spaced apart along the second direction y, and each pair of suction cups 221 includes two adjacently arranged suction cups 221 .

[0053] In the above solution, by providing multiple pairs of suction cups 221 , and each pair of suction cups 221 including two adjacent suction cups 221 , the adsorption assembly 22 can effectively adsorb the plate 50 , thereby reducing the risk of the plate 50 falling.

[0054] According to some embodiments of the present application, the adsorption assembly 22 includes two pairs of suction cups 221 , and along the second direction y, the two pairs of suction cups 221 are symmetrically arranged relative to the middle of the fixing rod 220 .

[0055] In the above solution, by symmetrically arranging two pairs of suction cups 221 along the middle of the fixed rod 220, it is possible to provide uniform adsorption force to the plate 50, thereby reducing the risk of the plate 50 tilting due to uneven adsorption force, causing the plate feeding roller 33 to apply uneven force to the plate 50, resulting in the plate 50 being unable to be effectively transported to the next process.

[0056] According to some embodiments of the present application, the roller plate feeding mechanism 30 is disposed on a side of the frame 21 away from the adsorption assembly 22 along the first direction x.

[0057] In the above solution, by integrating the roller plate feeding mechanism 30 with the frame 21, the space utilization rate of the plate loading system 100 can be effectively improved, so that the plate loading system 100 has a compact structure and occupies a small area.

[0058] According to some embodiments of this application, see Figure 4 , Figure 4 Schematic diagram of the roller plate feeding mechanism 30 in some embodiments of the present application.

[0059] The roller plate feeding mechanism 30 includes a mounting rod 31, a driving assembly 32 and a plurality of plate feeding rollers 33. The mounting rod 31 is connected to the frame 21 at both ends along the second direction y. The plurality of plate feeding rollers 33 are hinged on the mounting rod 31. The driving assembly 32 is connected to the frame 21 and is used to drive the plate feeding rollers 33 to deflect relative to the mounting rod 31 to contact or leave the plate 50 transported by the front end plate feeding mechanism 20.

[0060] It should be noted that some embodiments provided in this application can be improved based on the roller plate feeding mechanism 30 currently on the market. The improvements may involve the drive component 32. The specific structure of the drive component 32 is described below. Among them, the plate feeding roller 33 and the mounting rod 31 can be existing technologies and will not be described in detail.

[0061] According to some embodiments of the present application, the driving assembly 32 includes a steel belt type rodless cylinder 320, a moving rod 321, an auxiliary guide mechanism 322 and a push rod 323; the steel belt type rodless cylinder 320 is arranged on the frame 21 and is used to drive the moving rod 321 to move along the first direction x, the auxiliary guide mechanism 322 is arranged between the moving rod 321 and the frame 21, and is used to guide the moving rod 321 to slide relative to the frame 21 along the first direction x, and the push rod 323 is connected to the moving rod 321, and is used to drive the feeding plate roller 33 to deflect.

[0062] In the above-mentioned solution, compared with the current solution of the plate loading system 100 using a magnetically coupled rodless cylinder, the steel belt rodless cylinder 320 is more durable, and in conjunction with the auxiliary guide mechanism 322, it can stably enable the moving rod 321 to drive the push rod 323 to move back and forth along the first direction x, so as to effectively deflect the plate feeding roller 33, thereby effectively driving the plate 50 to the next process.

[0063] According to some embodiments of this application, see Figure 5 , Figure 5 for Figure 2 Enlarged view of point A in the middle.

[0064] The auxiliary guide mechanism 322 includes a guide rod 3220 and a guide wheel 3221 . The guide wheel 3221 is rotatably disposed on the movable rod 321 . The guide rod 3220 is fixed to the frame 21 and extends along the first direction x. The guide wheel 3221 and the guide rod 3220 are in rolling engagement.

[0065] In the above solution, through the rolling cooperation between the guide rod 3220 and the guide wheel 3221 , the moving rod 321 can be stably moved along the first direction x under the drive of the steel belt type rodless cylinder 320 .

[0066] According to some embodiments of the present application, along the second direction y, the steel belt type rodless cylinder 320 is located in the middle of the moving rod 321.

[0067] There are two auxiliary guide mechanisms 322 , and the two auxiliary guide mechanisms 322 are symmetrically arranged relative to the middle of the moving rod 321 .

[0068] In the above scheme, the steel belt type rodless cylinder 320 is located in the middle of the moving rod 321, and the two auxiliary guide mechanisms 322 are symmetrically arranged relative to the middle of the moving rod 321, so that the moving rod 321 can be evenly stressed, so as to stably drive the feeding roller 33 to deflect through the push rod 323.

[0069] According to some embodiments of the present application, both ends of the mounting rod 31 along the second direction y are hingedly engaged with the frame 21 .

[0070] In the above solution, by hingedly coupling the end plate of the mounting rod 31 with the frame 21 , the flexibility of the mounting rod 31 can be improved, and the risk of structural damage to the mounting rod 31 caused by the impact of the plate on the mounting rod 31 can be reduced.

[0071] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
