Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, and specifically to an EVA antistatic foam laser cutting machine. Background Technology

[0002] EVA antistatic foam is usually made by adding a certain amount of conductive carbon powder and other conductive materials during the foaming process, and then molding it with instruments. EVA antistatic foam is often used to make packaging boxes for plug-in boards and printed circuit boards, as well as antistatic cushioning pads and turnover packaging for electronic components and production lines. It can also be used as electromagnetic shielding material in computer rooms, which can effectively protect integrated circuits, microelectronic components, optoelectronic active devices, high-frequency filters and other components from the damage caused by static electricity, vibration and impact.

[0003] When using EVA antistatic foam, a suitable load-bearing structure needs to be cut from the foam board using a laser cutting machine. However, after cutting, because foam is a flexible and elastic structure, the foam product cannot be automatically separated from the foam waste. The two remain connected and require manual separation of the foam waste from the foam product before sorting and outputting. This increases the laser cutting production process and reduces the efficiency of laser cutting production. Summary of the Invention

[0033] 1.

[0034] 2. The composite cooling component can be used to cool the laser cutting head with air or water, effectively reducing the working temperature of the laser cutting head and ensuring stable operation of the laser cutting head;

[0035] 3. The top material assembly can achieve the following effects: it can be adjusted to a narrow contact mode, which can stabilize the small-sized foam waste cut by the laser in the first mode, so that the negative pressure suction assembly can quickly suck it away; it can be adjusted to a wide contact mode, which can push the foam frame from below in the second mode, so as to avoid the foam frame being deformed downward by the force when the piercing and picking assembly is piercing, thereby improving the piercing speed and smoothness of the piercing and picking assembly.

[0036] 4. The piercing and picking component can achieve the following effects: In the second mode, the piercing and picking component can be adjusted to a planar mode, which can press down the small-sized foam products cut out, so that the foam products are separated from the foam frame and the material is quickly unloaded; In the second mode, since the foam frame is waste material and is relatively large, it cannot be directly attracted by the negative pressure suction component. Therefore, the piercing and picking component can be adjusted to a piercing mode, so that the piercing and picking component can pass through the foam frame. Then, when the piercing and picking component is lifted, it can take the foam frame to the crushing and recycling component and achieve rapid recycling. Attached Figure Description

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] To address the technical problems mentioned in the background section, the following EVA antistatic foam laser cutting machine is provided:

[0053] Combination Figures 1-12 As shown, the present invention provides an EVA antistatic foam laser cutting machine, which includes a first horizontal guide rail 1, which is symmetrically arranged in two sets;

[0054] The discharge conveyor belt 11 is installed at the bottom between the two sets of first transverse guide rails 1, and the discharge conveyor belt 11 is used to output foam products.

[0055] The laser cutting assembly 2 includes a first longitudinal guide rail 21, a vertical guide rail 22, a laser cutting head 23, and a composite cooling assembly 24. The first longitudinal guide rail 21 is spaced at the top end of the side guide rail. The vertical guide rail 22 is slidably mounted on the side of the first longitudinal guide rail 21. The laser cutting head 23 is vertically slidably mounted on the outer wall of the vertical guide rail 22. The composite cooling assembly 24 is mounted on the outside of the laser cutting head 23. The composite cooling assembly 24 is used to reduce the temperature of the laser cutting head 23 by liquid-air combination.

[0056] The main frame 3 is horizontally slidably mounted on the top of the first horizontal guide rail 1;

[0057] The inner constraint component 4 includes an inner frame 41, a rotating shaft 42, a longitudinal sliding plate 43, and a clamping corner plate 44. The inner frame 41 has a rotating shaft 42 at the middle of both ends. The rotating shaft 42 is rotatably connected to the transverse centerline of the outer frame. One end of the main frame 3 is provided with a first motor 46 that drives the inner frame 41 to rotate. Two sets of longitudinal sliding plates 43 are symmetrically slidable laterally on the surface of the inner frame 41. Two sets of clamping corner plates 44 are symmetrically slidable longitudinally on the surface of the longitudinal sliding plates 43. The clamping corner plates 44 are used to clamp the four corners of the positioning foam board.

[0058] Top material assembly 5 is slidably installed on the bottom surface of inner frame 41;

[0059] The piercing and material-retrieving assembly 6 is installed above the inner frame 41;

[0060] The negative pressure suction assembly 7 is installed on the side of the laser cutting head 23;

[0061] The crushing and recycling component 8 is located on one side of the horizontal guide rail. The crushing and recycling component 8 is used to recycle the foam waste output by the piercing and feeding component 6 and the negative pressure suction component 7.

[0062] Foam laser cutting machines include the following operating modes:

[0063] In the first mode, the foam cut by laser is waste material and the remaining foam frame is product material: the top material component 5 is adjusted to narrow contact mode and tops the foam waste material, the negative pressure suction component 7 attracts the topped foam waste material and discharges it to the crushing and recycling component 8; after the foam waste material is discharged, the inner frame 41 rotates to release the foam product to the discharge conveyor belt 11.

[0064] In the second mode, the laser-cut foam is the product material, and the remaining foam frame is waste material: the piercing and picking component 6 is adjusted to the flat mode, pressing the foam product down to the discharge conveyor belt 11; after the foam product is discharged, the piercing and picking component 6 is adjusted to the piercing mode and moves to the top of the foam frame piercing position, the top material component 5 is adjusted to the wide contact mode and moves to the bottom of the foam frame piercing part, the top material component 5 stably lifts the piercing part from below so that the piercing and picking component 6 can smoothly pass through the foam frame, and the piercing and picking component 6 is lifted and moved outward to transfer the foam frame to the crushing and recycling component 8.

[0065] In the above scheme:

[0066] 1. Setting internal constraint components can achieve the following effects:

[0067] 1.1 The two sets of longitudinal sliding plates can be slid laterally for one adjustment, and the clamping corner plate can be slid longitudinally for a second adjustment. In this way, foam boards of different sizes can be constrained and positioned.

[0068] 1.2 The first motor can drive the inner frame to rotate to meet the material feeding requirements of foam frame products;

[0069] 2. The composite cooling component can be used to cool the laser cutting head with air or water, effectively reducing the working temperature of the laser cutting head and ensuring stable operation of the laser cutting head;

[0070] 3. The top material assembly can achieve the following effects:

[0071] 3.1 It can be adjusted to a narrow contact mode, which can stabilize small-sized foam waste cut by the top laser in the first mode, so that the negative pressure suction component can quickly suck it away;

[0072] 3.2 It can be adjusted to a wide contact mode, which can push the foam frame upward from below in the second mode to avoid the foam frame deforming downward under force when the piercing and picking component is piercing, thereby improving the piercing speed and smoothness of the piercing and picking component.

[0073] 4. The piercing and material-picking component can achieve the following effects:

[0074] 4.1 In the second mode, the piercing and picking component can be adjusted to a planar mode, which can press down the small-sized foam products cut out, so that the foam products are separated from the foam frame and the material is fed out quickly.

[0075] 4.2 In the second mode, since the foam frame is waste material and is large in size, it cannot be directly attracted by the negative pressure suction component. Therefore, the piercing and picking component can be designed to be adjusted to piercing mode. In this way, the piercing and picking component can pass through the foam frame. Then, when the piercing and picking component is lifted, it can take the foam frame to the crushing and recycling component to achieve rapid recycling.

[0076] 5. The negative pressure suction component can absorb small-sized foam waste materials and also remove the working heat of the laser cutting head during operation, thus helping to reduce the working temperature of the laser cutting head.

[0077] In this embodiment, the clamping angle plate 44 is L-shaped, and a central sliding groove 431 is provided inside the longitudinal sliding plate 43. A first moving block 442 is provided at the bottom of the clamping angle plate, and the first moving block 442 is slidably installed in the central sliding groove 431. A pressing component is installed on the outer side of the clamping angle plate, and the pressing component is used to press the four corners of the foam board. The pressing component includes a first adjusting screw and a pressure plate 45. A vertical groove 441 is provided on the side of the clamping angle plate 44, and the pressure plate 45 is horizontally placed in the clamping angle plate 44. One end of the pressure plate 45 slides through the vertical groove 441. The first adjusting screw 47 is provided on the outer wall of the clamping angle plate 44, and the first adjusting screw threaded through the extended end of the pressure plate 45.

[0078] In the above scheme: the screw drives the first moving block to move, which in turn drives the clamping corner plate to move inward to adapt to the size of the foam board. The pressure plate is initially placed on top of the clamping corner plate, and the four corners of the foam board are inserted into the clamping corner plate. Then the first adjusting screw rotates to drive the pressure plate to move downward along the vertical groove, and the pressure plate presses down to position the foam board.

[0079] In this embodiment, the top-feeding assembly 5 includes a movable frame 51, a second movable block 52, a second adjusting screw 53, a top pipe 56, and a top rod 57. The movable frame 51 is slidably installed on the bottom surface of the inner frame 41. The movable frame 51 is longitudinally distributed. The second movable block 52 is slidably installed longitudinally inside the movable frame 51. The second adjusting screw 53, which drives the second movable block 52, is installed inside the movable frame 51. A first driving rod 54 is vertically provided on the bottom surface of the second movable block 52. A base plate 55 is provided at the bottom end of the first driving rod 54. The transversely extending movable frame 51 of the base plate 55 has a top tube 56 vertically provided on the extended end surface. The side wall of the top tube 56 has symmetrically opened notches. The top end of the top rod 57 is rotatably connected to the inner top of the top tube 56, and a second motor 58 is installed at the rotatable connection. In the narrow contact mode, the two sets of top rods 57 rotate downward and retract into the top tube 56. In the wide contact mode, the two sets of top rods 57 rotate upward in a V shape. The two sets of top rods 57 extend out of the top tube 56 and push the foam frame above. The top tube 56 is used for the tip of the piercing and picking component 6 to be inserted.

[0080] In the above scheme: In order to meet the needs of the top-mounting at different positions, the moving frame can move along the inner frame, and then the second adjusting screw drives the second moving block to move so that the top tube is located below the top-mounting position; in the narrow mode, the top tube is topped alone, so the contact surface is smaller and can meet the needs of the top-mounting of foam waste of different sizes; in the wide mode, the top material assembly needs to top the foam frame, but it cannot affect the piercing action of the piercing and picking assembly. Therefore, the second motor is designed to drive two sets of top rods to rotate upward in a V shape. In this way, the top rods extend upward outward from the top tube, the top rods contact the top foam frame, and the top tube and the foam frame leave a piercing gap.

[0081] In this embodiment, the piercing and material-taking assembly 6 includes a second longitudinal guide rail 61, which is disposed on the side of the crushing and recycling assembly 8. A support plate 611 is slidably mounted on the top of the second longitudinal guide rail 61. A second transverse guide rail 62 is vertically distributed on the top of the support plate 611. A third longitudinal guide rail 63 is vertically slidably mounted on the side of the second transverse guide rail 62. The third longitudinal guide rail 63 is horizontally disposed above the inner constraint assembly 4. A piercing and material-taking component is vertically slidably mounted on the bottom surface of the third longitudinal guide rail 63.

[0082] In the above scheme: during the piercing and material-taking action, the third longitudinal guide rail moves along the second transverse guide rail, and the piercing and material-taking component moves along the third longitudinal guide rail, so that the piercing and material-taking component moves to above the piercing part; after piercing is completed, the support plate moves along the second longitudinal guide rail, so that the piercing and material-taking component drives the foam board to move above the crushing and recycling component.

[0083] In this embodiment, the puncture and extraction component includes a receiving plate 64, a second drive rod 65, a receiving tube 66, and a puncture needle 67. The receiving plate 64 is slidably mounted on the bottom of the third longitudinal guide rail 63. A movable plate 641 is damped and slidably embedded in the bottom of the receiving plate 64. A horizontal connecting plate 642 is provided on the bottom side wall of the movable plate 641. The outer end of the horizontal connecting plate 642 is vertically connected to the vertically downward receiving tube 66. The puncture needle 67 is vertically slidably mounted inside the receiving tube 66. The second drive rod 65 is installed on the side of the storage plate 64. The output end of the second drive rod 65 is connected to the puncture needle 67. The top side wall of the puncture needle 67 is provided with a locking groove 671 and a lower locking groove 673. The top of the storage tube 66 is provided with a through hole 661. The bottom surface of the horizontal connecting plate 642 is slidably provided with a locking insert plate 68. The bottom of the puncture needle 67 is symmetrically and rotatably equipped with a stop bar 672 and a torsion spring is installed at the rotatable connection. The side of the puncture needle 67 is provided with a notch.

[0084] When the puncture and material extraction assembly 6 is in planar mode, the puncture needle 67 is fully retracted into the storage tube 66, the locking plate is inserted into the lower locking groove, the stop rod 672 rotates downward to retract into the puncture needle 67 and compresses the torsion spring, and the locking plate 68 connects the storage tube 66 and the puncture needle 67 into one unit.

[0085] When the piercing and picking assembly 6 is in piercing mode, the following working steps are included: S1, the locking plate 68 is first unlocked, so that the piercing needle 67 is separated from the storage tube 66, the second drive rod 65 first drives the needle tip of the piercing needle 67 to extend outward, the stop rod 672 is placed inside the storage tube 66, and the locking plate 68 is then inserted into the upper locking groove; S2, the second drive rod 65 drives the storage tube 66 to descend, so that the tip of the piercing needle 67 and the storage tube 66 pierce the foam frame; S3, the locking plate 68 is unlocked, the piercing needle 67 moves downward alone, the stop rod 672 disengages from the storage tube 66 and gradually rotates upward until the stop rod 672 is attached to the bottom surface of the foam frame.

[0086] In the above scheme:

[0087] 1. In planar mode, the locking plate can move laterally and can be inserted into the locking groove of the puncture needle, so that the puncture needle and the collection tube are integrated. In this way, the puncture needle is stably placed in the collection tube. When the second drive rod drives the collection tube to move downward, it will drive the collection tube to move downward. In this way, the planar collection tube can directly press down small-sized foam waste materials to achieve rapid material discharge.

[0088] 2. In puncture mode, the tip of the puncture needle extends outward from the storage tube to achieve puncture, but the stop bar cannot be exposed in advance, as this would affect the puncture process. Therefore, only the tip is exposed in the first step. In S2, the tip of the puncture needle and the bottom of the storage tube pass through the foam frame simultaneously, and the storage tube maintains the constraint on the stop bar. In S3, after the storage tube extends outward, the stop bar can rotate upward. Therefore, when unlocked again, the puncture needle moves downward alone, and the torsion spring can drive the stop bar to rotate upward automatically. The stop bar can then extend outward and stop below the foam frame. In this way, when the puncture needle is lifted, the stop bar can drive the foam frame to move above the crushing and recycling component. Then, the puncture needle is completely retracted into the storage tube again, and the foam frame can fall down automatically.

[0089] In this embodiment, the composite cooling assembly 24 includes a cooling box 241, which is located outside the laser cutting head 23. The bottom of the cooling box 241 is a liquid cooling cavity 242, and the top of the cooling box 241 is an air cooling cavity 243. The cross-section of the liquid cooling cavity 242 is U-shaped. One side of the liquid cooling cavity 242 is a liquid inlet, and the other side is a liquid outlet. The two longitudinal sides of the liquid cooling cavity 242 are connecting parts. Multiple sets of cooling baffles 26 are installed at intervals inside the connecting parts. The multiple sets of cooling baffles 26 form a serpentine liquid guiding channel. The top of each set of cooling baffles 26 is sealed and extends into the air cooling cavity 243.

[0090] In the above scheme: the liquid cooling cavity at the bottom is designed as the main heat exchange area, and the external liquid storage tank can circulate and supply coolant; the coolant enters through the inlet and then enters the outlet through the serpentine liquid guiding channels on both sides; the cooling baffles in the serpentine liquid guiding channels can conduct the heat in the liquid cooling cavity to the air cooling cavity. The design of the cooling baffles in a serpentine distribution can increase the contact path between the coolant and the cooling baffles and improve the heat dissipation effect of the coolant.

[0091] In this embodiment, the negative pressure suction assembly 7 includes a suction hood 71, a secondary support arm 72 is provided on the side wall of the suction hood 71, the secondary support arm 72 is horizontally slidably mounted on the top of the main support arm 73, the end of the main support arm 73 is rotatably connected to the side plate 74 and a third motor 75 is installed at the rotatable connection, and the outlet end of the suction hood 71 is connected to the guide hose 76.

[0092] In the above scheme: the negative pressure suction component can follow the movement of the laser cutting head. When the laser cutting head cuts the next position, the suction hood can be placed at the waste material after the previous cut. In order to adapt to the suction needs of waste material at different positions, the third motor can drive the main support arm to rotate to adjust the suction angle. The secondary support arm can move along the main support arm to further change the suction hood.

[0093] In this embodiment, the bottom side of the cooling box 241 is provided with a side smoke extraction plate 25, the side of the suction hood 71 is provided with an air guide mesh 711, a side cover 712 is installed outside the air guide mesh 711, a cold air fan 77 is installed inside the side cover 712, a filter pad 78 is installed outside the cold air fan 77, and the outside of the side cover 712 is connected in parallel to the air-cooling chamber 243 and the side smoke extraction plate 25 through a duct; when the crushing and recycling component 8 is not working, the cold air fan 77 is working; when the crushing and recycling component 8 is working, the cold air fan 77 is not working.

[0094] In the above scheme: the side smoke extraction plate can directly attract the smoke from laser cutting, and then the smoke is discharged to the side cover through an independent duct. The filter pad can absorb and filter the smoke.

[0095] The system is equipped with air guide mesh and a cooler. When the crushing and recycling component is not working, the cooler operates independently to ensure flue gas adsorption and cooling of the cooling baffle. This generates negative pressure airflow in the air-cooled cavity to quickly remove heat from the cavity and lower the temperature of the cooling baffle. When the crushing and recycling component is working, the cooler does not need to operate. The negative pressure generated by the crushing and recycling component is transmitted to the air-cooled cavity and side smoke extraction plate through the air guide mesh to reduce energy consumption.

[0096] In this embodiment, the crushing and recycling assembly 8 includes a recycling box 81. The recycling box has an internal partition 88, with an upper cavity at the top and a lower cavity at the bottom. A vertically arranged lower partition 82 is installed inside the lower cavity. A suction fan 84 is installed on one side of the lower partition, and a crushed material storage chamber 811 is located on the other side. An extrusion plate 89 is installed inside the crushed material storage chamber. An upper partition 83 is vertically slidably installed inside the lower partition. The area between the partition and the suction fan has a mesh structure. Through holes are provided at the positions opposite to the upper partition and the crushed material storage chamber of the middle partition; a horizontally sliding pusher plate 85 is installed at one end of the upper cavity, and a crushing toothed roller 86 is installed at the other end of the upper cavity, with the crushing toothed roller located above the crushed material storage chamber; an opening for the foam frame to enter is provided at the top of the recycling box, and a sealing plate 87 is horizontally slidably installed on the opening. A feed pipe 871 is vertically provided on the surface of the sealing plate, and the feed pipe is connected to the guide hose, with the feed pipe located above the exhaust fan.

[0097] In the above scheme: when it is necessary to attract waste, the upper partition moves upward into the upper cavity and abuts against the sealing plate. In this way, the upper part of the suction fan is a closed structure, which avoids the dispersion of negative pressure and makes the negative pressure wind force accurately act on the suction hood.

[0098] After the small-sized foam waste is attracted, the upper partition descends to the side of the lower partition. Then, the pusher plate moves along the upper cavity to push the foam waste to the crushing roller. The crushing roller rotates and crushes the foam waste. The crushed pieces fall into the fragment storage chamber. The crushing method increases the storage capacity of the fragment storage chamber. Then, the extrusion plate moves to compress the fragments and further reduce the volume occupied by the fragments.

[0099] When the waste material is a foam frame, the sealing plate moves outward, exposing the opening. In this way, the foam frame falls onto the middle partition, and the pusher plate pushes it, so that the crushing toothed roller can continue to crush the foam frame.
