Description

Technical Field

[0001] The invention relates to an optical element processing device, in particular to a hot-melt light guide plate processing device and method. Background Art

[0002] The light guide plate is a product made of optical-grade acrylic or PC sheets. By using high-tech materials with extremely high refractive index and no light absorption on the bottom of the sheet, laser engraving, V-shaped cross grid engraving or UV screen printing technology are used to print light guide points, so that the light stays on the surface of the sheet and reflects and diffuses, thereby achieving a uniform luminous effect. As an important part of the optical system, it usually needs to be precisely combined with metal parts to achieve structural functions. Traditional bonding methods, such as bonding or mechanical assembly, have problems such as low bonding strength, complex processes, and easy aging. Although hot melt technology is an existing technology, there is still a lack of a set of automated equipment and processes for batch-based automated hot melt bonding of light guide plates and copper parts, so as to achieve the purpose of large-scale batch splicing between light guide plates. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a hot-melt light guide plate processing equipment and method, so that the light guide plate can be reliably connected with the metal parts through batch hot-melt operations while maintaining the optical performance and structural integrity of the light guide plate.

[0004] The present invention provides the following technical solutions: A hot-melt light guide plate processing equipment and method, comprising a copper heating box, a hot-melt assembly box arranged at the lower layer of the copper heating box, and a cooling box connected to the outlet end of the hot-melt assembly box, wherein the copper heating box is used to heat the copper body to 300°C-400°C, the hot-melt assembly box is used to receive and position the light guide plate body to cooperate with the hot-melt assembly of the copper body in the copper heating box, and the cooling box is used to cool the copper body and the light guide plate body after hot-melt assembly; The bottom of the copper heating box is provided with a through hole which is connected with the hot melt assembly box, the through hole is blocked by a sealing plate, and a group of rotating frames are also installed in the copper heating box, the rotating frames are used to drive the copper body to rotate to the top of the through hole in a circumferential direction in sequence, and when the sealing plate is opened, the copper body falls into the hot melt assembly box along the through hole, and the hot melt assembly box enters the carrier plate with the light guide plate body positioned from the entrance end, and when the positioning hole on the light guide plate body moves to the bottom of the through hole, it is used to receive the copper body falling from the through hole, and a group of pressing cylinders are also installed on the copper heating box, and the driving end pressing rod of the pressing cylinder is used to pass through the through hole to press the copper body into the positioning hole of the light guide plate body; At this point, after the positioning holes are processed by CNC equipment on the light guide plate body, it can be placed in the carrier plate and enter from the entrance end of the hot melt assembly box. The copper body in the copper heating box is heated separately to 300°C-400°C. After that, when the positioning holes of the light guide plate body are moved to the bottom of the through-hole, the sealing plate is opened, so that the copper body above the through-hole falls onto the positioning holes. Since the temperature of the copper body is relatively high, when it contacts the light guide plate body, the higher temperature will cause the positioning hole accessories to soften, and then the driving end pressure rod of the pressure cylinder passes through the through-hole to slowly press the copper body into the positioning hole of the light guide plate body, thereby realizing the hot melt combination of the copper body and the light guide plate body. This combination can ensure higher processing accuracy and greater bonding strength, because the copper body can be various shapes that can adapt to different positioning holes, so the scope of application is also wider, and the copper A threaded structure for connecting with different light guide plate bodies can also be set in the body of the component, so the reliability of the light guide plate bodies when connected to each other can be significantly improved, and the modular combination design of the overall structure and the automated loading and unloading system can also greatly improve the production efficiency and product quality. Since the copper component body and the light guide plate body are each in an independent and sealed environment, the processing accuracy can be further improved, and the influence of the external environment on the hot melt combination can be reduced. At the same time, it is also more convenient to load and unload each workpiece separately, so as to facilitate batch production. After the copper component body and the light guide plate body are press-assembled by the pressure cylinder, they can be directly transported to the cooling box and cooled to room temperature by natural cooling or accelerated cooling by cold air to ensure that the material recovers its strength.

In this way, the stability of the rotation of the rotating frame can be ensured. At the same time, the rotating drive cylinder is arranged on the top of the copper heating box, which can also reduce the influence of high temperature on the rotating drive cylinder.

[0008] Preferably, one end of the sealing plate is connected to a group of sealing cylinders, which are installed in the partition between the copper heating box and the hot melt assembly box and are used to horizontally push the sealing plate to seal the through opening to achieve a barrier effect between the copper heating box and the hot melt assembly box.

[0009] Preferably, a connecting pipe located in the hot melt assembly box is also provided below the through-port, and the connecting pipe has a falling hole which is connected to the through-port to allow the copper body to freely guide and fall, so as to ensure that when the light guide plate body is at a large distance from the top of the light guide plate box, the copper body will not be displaced during the process of falling to the positioning hole.

[0010] Preferably, the connecting pipe includes an upper connecting pipe fixedly connected to the top of the hot melt assembly box, a pushing cylinder fixed outside the upper connecting pipe and a lower connecting pipe connected to the driving end of the pushing cylinder, the upper connecting pipe and the lower material pipe are coaxially arranged, and the port joints of the upper connecting pipe and the lower connecting pipe are also provided with plug-in rods distributed crosswise with each other, and when the plug-in rods of the upper connecting pipe and the lower connecting pipe are crosswise distributed, a side wall of a falling hole is formed for guiding the copper body to fall freely, and the pushing cylinder is used to push the lower connecting pipe to abut against the light guide plate body moved into place, so as to extend the length of the falling hole, so that the copper body can be kept in the falling hole until it falls onto the light guide plate body, and at the same time, when the light guide plate body moves, the pushing cylinder can also lift the lower connecting pipe to separate from the light guide plate body so as not to scratch the surface of the light guide plate body; The bottom end of the lower connecting tube is also provided with at least two groups of elastic support groups, and the elastic support groups are evenly distributed along the circumference of the lower connecting tube, and include a support block, an end slider and a spring.

When the box door at the inlet end is opened, the carrier plate can slide into the hot melt assembly box through the inlet end guide with the positioned light guide plate body, and the two sets of gears on both sides thereof are aligned and close to the inlet end. Under the synchronous drive of the two sets of gears, they completely enter the hot melt assembly box along a straight line, and mesh with the other two sets of gears when close to the outlet end until the positioning holes on the light guide plate body on them move to the through opening and stop moving. After the press-fitting is completed, the box door at the outlet end can be opened, and the two sets of gears close to the outlet end can synchronously drive the carrier plate guide to slide into the cooling box. At the same time, the inlet end can also simultaneously load the next set of carrier plates, so as to complete batch production operations.

[0012] Preferably, the carrier is provided with holes for inserting positioning rods for circumferentially positioning the light guide plate body. Here, the positioning rod group is inserted and installed in the holes to form positioning for the light guide plate body on the carrier.

[0013] The opening position of this plug hole needs to ensure that after the light guide plate body is positioned, the carrier plate moves with the light guide plate body in a straight line to a certain distance, so that the positioning hole on the light guide plate body can be exactly located below the through-hole. When the size of the light guide plate body changes, the re-position of the plug hole can be debugged. The specific debugging steps are as follows: first, the carrier plate can be moved in a straight line into the hot melt assembly box, and then the debugged light guide plate body is placed on the carrier plate, and its positioning hole is located below the through-hole, and then the corresponding plug holes are drilled on the carrier plate around the outer periphery of the light guide plate body. When the batch is mass-produced in the future, it is only necessary to place the light guide plate body directly on the carrier plate, and insert the positioning rod into the new plug hole to limit the periphery of the light guide plate body. A method for processing a hot-melt light guide plate, based on the above-mentioned hot-melt light guide plate processing equipment, is characterized by comprising the following steps: S1: Place the light guide plate body on the corresponding carrier plate for positioning, place the copper body in the corresponding heat conduction block, and then install multiple sets of heat conduction blocks on the rotating frame in a circumferential direction, close the door of the copper heating box, and start the heating button of the copper heating box, so that the heating module in the copper heating box heats the copper body, and at the same time open the door of the hot melt assembly box entrance end, slide the carrier plate with the light guide plate body positioned into the hot melt assembly box along the straight line guide, close the door of the hot melt assembly box entrance end, and after the copper body is heated to 300°C-400°C, when the positioning hole of the light guide plate body also moves to the bottom of the through-hole, hot melt assembly processing is performed; S2: In the hot-melt combination of the light guide plate body and the copper body, the rotating frame is started to rotate, so that a group of copper bodies rotate to the top of the through-hole, and then the sealing plate is opened, and the copper body falls along the through-hole to the positioning roller, and the driving end pressure rod of the pressure cylinder passes through the positioning cavity and the through-hole to slowly press the copper body into the positioning hole of the light guide plate body, and then the driving end pressure rod of the pressure cylinder returns to the copper heating box, and the sealing plate is blocked again; S3: After the hot-melt assembly of the light guide plate body and the copper body, the door at the outlet of the hot-melt assembly box is opened, and the carrier plate is driven to slide out of the hot-melt assembly box and enter the cooling box. Then, the door at the outlet of the hot-melt assembly box is closed, and the door at the inlet of the hot-melt assembly box is opened. The next group of carrier plates are started to drive the light guide plate body into the hot-melt assembly box and the operations in S1 and S2 are repeated. The hot-melt-finished light guide plate body is cooled naturally or accelerated by cold air on the cooling platform in the cooling box to room temperature and wait for discharge to ensure that the material recovers its strength.

[0014] The beneficial effects of the present invention are as follows: the hot-melt light guide plate processing equipment and method provided by the present invention can realize the reliable connection between the light guide plate and the metal parts through batch hot-melt operation, while maintaining the optical performance and structural integrity of the light guide plate; In actual operation, after the positioning holes are machined on the light guide plate body using CNC equipment, they can be placed in the carrier plate and enter from the entrance end of the hot melt assembly box. The copper body in the copper heating box is heated separately to 300°C-400°C. After that, when the positioning holes of the light guide plate body are moved to the bottom of the through-hole, the sealing plate is opened, so that the copper body above the through-hole falls onto the positioning holes. Since the temperature of the copper body is relatively high, when it contacts the light guide plate body, the high temperature will cause the positioning hole accessories to soften, and then the driving end pressure rod of the pressure cylinder passes through the through-hole to slowly press the copper body into the positioning hole of the light guide plate body, thereby realizing the hot melt combination of the copper body and the light guide plate body. This combination can ensure higher processing accuracy and greater bonding strength, because the copper body can be various shapes that can adapt to different positioning holes, so it has a wider range of applications. Moreover, a threaded structure for connecting with different light guide plate bodies can be arranged in the copper body, thus significantly improving the reliability of the light guide plate bodies when connected to each other, and the modular combination design of the overall structure and the automated loading and unloading system can also greatly improve the production efficiency and product quality, and because the copper body and the light guide plate body are each in an independent and sealed environment, the processing accuracy can be further improved, and the influence of the external environment on the hot melt combination can be reduced, and it can also be more convenient to load and unload the respective workpieces separately, so as to facilitate batch production, and after the copper body and the light guide plate body are press-assembled by the pressure cylinder, they can be directly transported to the cooling box, cooled to room temperature by natural cooling or accelerated cooling by cold wind, so as to ensure that the material recovers its strength, and the inner hole of the copper body can be provided with a thread, so as to achieve the effect of more forms of connection between the light guide plate bodies; In order to adapt to the automated batch input, positioning, docking and assembly of the light guide plate body driven by the carrier plate, the carrier plate is set as a simple linear drive. At this time, in order to ensure that it can better adapt to the production of different batches, a socket is set on the carrier plate to limit the periphery of the light guide plate body through the plug rod. The opening position of this socket needs to ensure that after the light guide plate body is positioned, the carrier plate moves along a straight line with the light guide plate body to a certain distance, so that the positioning hole on the light guide plate body can be exactly located below the through-hole. When the size of the light guide plate body changes , the re-positioning of the socket can be debugged, and the specific debugging steps are as follows: first, the carrier plate can be moved in a straight line into the hot melt assembly box, and then a group of light guide plate bodies of the debugging batch can be placed on the carrier plate, and their positioning holes are located below the through-holes, and then corresponding sockets are drilled on the carrier plate around the outer periphery of the light guide plate body. At this point, when carrying out mass production of this batch, it is only necessary to place the light guide plate body directly on the carrier plate, and insert the positioning rod into the new socket to limit the periphery of the light guide plate body. At this point, after the electrically driven carrier plate moves the same distance, assembly can be carried out. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Example 1 like Figure 1-4 As shown, a hot-melt light guide plate processing equipment, in this embodiment, includes a copper heating box 1, a hot-melt assembly box 2 arranged at the lower layer of the copper heating box 1, and a cooling box 3 connected to the outlet 11 of the hot-melt assembly box 2. The copper heating box 1 is used to heat the copper body 6 to 300°C-400°C, the hot-melt assembly box 2 is used to receive and position the light guide plate body 5 to cooperate with the hot-melt assembly of the copper body 6 in the copper heating box 1, and the cooling box 3 is used to cool the copper body 6 and the light guide plate body 5 after the hot-melt assembly; The bottom of the copper heating box 1 is provided with a through hole 7 which is connected with the hot melt assembly box 2. The through hole 7 is blocked by a sealing plate 8. A group of rotating frames 9 are also installed in the copper heating box 1. The rotating frames 9 are used to drive the copper body 6 to rotate to the top of the through hole 7 in a circumferential direction. When the sealing plate 8 is opened, the copper body 6 falls into the hot melt assembly box 2 along the through hole 7. The hot melt assembly box 2 enters the carrier plate 4 with the light guide plate body 5 positioned thereon from the entrance end 10. When the positioning hole 12 on the light guide plate body 5 moves to the bottom of the through hole 7, it is used to receive the copper body 6 falling from the through hole 7. A group of pressing cylinders 13 are also installed on the copper heating box 1. The driving end pressing rod 14 of the pressing cylinder 13 is used to pass through the through hole to press the copper body 6 into the positioning hole 12 of the light guide plate body 5. At this point, after the positioning hole 12 is processed by CNC equipment, the light guide plate body 5 can be placed in the carrier plate 4 and enter through the inlet end 10 of the hot melt assembly box 2. The copper body 6 located in the copper heating box 1 is heated separately to 300°C-400°C. After that, when the positioning hole 12 of the light guide plate body 5 moves to the bottom of the through-hole 7, the sealing plate 8 is opened, so that the copper body 6 above the through-hole 7 falls onto the positioning hole 12. Since the temperature of the copper body is relatively high, when it contacts the light guide plate body, the higher temperature will cause the positioning hole accessories to soften, and then the driving end pressure rod 14 of the pressure cylinder 13 also passes through the through-hole to slowly press the copper body 6 into the positioning hole 12 of the light guide plate body 5, so that the hot melt combination of the copper body 6 and the light guide plate body 5 can be achieved. The combination in this way can ensure higher processing accuracy and greater bonding strength, because the copper body 6 can be of various shapes that can adapt to different positioning holes 12. Therefore, the scope of application is also wider, and a threaded structure for connecting with different light guide plate bodies 5 can also be arranged in the copper body 6, so the reliability of the light guide plate bodies 5 when connected to each other can be significantly improved, and the modular combination design of the overall structure and the automatic loading and unloading system can also greatly improve the production efficiency and product quality. Since the copper body 6 and the light guide plate body 5 are respectively in independent and sealed environments, the processing accuracy can be further improved, and the influence of the external environment on the hot melt combination can be reduced. At the same time, it can also be more convenient to load and unload each workpiece separately, so as to facilitate batch production. After the copper body 6 and the light guide plate body 5 are press-assembled by the pressure cylinder 13, they can be directly transported to the cooling box 3, and cooled to room temperature by natural cooling or accelerated cooling by cold air to ensure that the material recovers its strength, and a thread can be arranged in the inner hole of the copper body 6 to achieve the effect of more forms of connection between the light guide plate bodies 5.

[0017] A plurality of groups of grooves are evenly arranged along the circumferential direction around the rotating frame 9, and a group of heat-conducting blocks 15 can be detachably installed in each group of grooves. A positioning cavity 16 matching the outer shape of the copper body 6 is provided at the center of the heat-conducting block 15, and a plurality of groups of heating tubes 17 are also arranged around the positioning cavity 16. Since the heat-conducting block 15 is detachably installed in the groove, it can be replaced and adjusted later, and the installation convenience is also better.

[0018] A group of connecting plates 18 are provided on the top of the heat conductive block 15, and the connecting plates 18 are fixedly connected to the rotating frame 9 by screws, so that each heat conductive block 15 can be detachably connected to the rotating frame 9, so as to facilitate the maintenance and replacement of the heat conductive block 15 at a later time.

[0019] A mounting block is provided at the center of the rotating frame 9, and a rotating drive cylinder 19 is installed on the top of the copper heating box 1. The driving end of the rotating drive cylinder 19 is connected to the mounting block to drive the rotating frame 9 to rotate. A rotating ring 20 is also provided around the rotating frame 9 and is installed at the bottom of the copper heating box 1. In this way, the stability of the rotation of the rotating frame 9 can be ensured. At the same time, the rotating drive cylinder 19 is arranged on the top of the copper heating box 1, which can also reduce the influence of high temperature on the rotating drive cylinder 19.

[0020] One end of the sealing plate 8 is connected to a group of sealing cylinders 21, which are installed in the partition between the copper heating box 1 and the hot melt assembly box 2, and are used to horizontally push the sealing plate 8 to seal the through opening 7 to achieve a barrier effect between the copper heating box 1 and the hot melt assembly box 2.

[0021] A connecting pipe located in the hot melt assembly box 2 is also provided below the through-port 7, and the connecting pipe has a falling hole that is connected to the through-port 7 for the copper body 6 to freely guide and fall, so as to ensure that when the light guide plate body 5 is at a large distance from the top of the light guide plate box, the copper body 6 will not be offset during the process of falling to the positioning hole 12.

[0022] The connecting pipe includes an upper connecting pipe 22 fixedly connected to the top of the hot melt assembly box 2, a pushing cylinder 24 fixed outside the upper connecting pipe 22 and a lower connecting pipe 23 connected to the driving end of the pushing cylinder 24. The upper connecting pipe 22 and the feeding pipe are coaxially arranged. The port joints of the upper connecting pipe 22 and the lower connecting pipe 23 are also provided with mutually cross-distributed plug-in rods 25. When the plug-in rods 25 of the upper connecting pipe 22 and the lower connecting pipe 23 are cross-distributed, the side wall of the falling hole for the copper body 6 to freely guide and fall is formed. The pushing cylinder 24 is used to push the lower connecting pipe 23 to abut against the light guide plate body 5 that has moved into place, so as to extend the length of the falling hole, so that the copper body 6 can remain in the falling hole until it falls onto the light guide plate body 5. At the same time, when the light guide plate body 5 moves, the pushing cylinder 24 can also lift the lower connecting pipe 23 to separate from the light guide plate body 5 so as not to scratch the surface of the light guide plate body 5. At least two groups of elastic support groups 30 are also provided at the bottom end of the lower connecting tube 23. The elastic support groups are evenly distributed along the circumference of the lower connecting tube, and include a support block 31, an end slider 32 and a spring 33. A support groove 34 extending in the radial direction is opened on the inner wall of the lower connecting tube 23. The support block 31 is inserted in the support groove 34, and a slide groove 35 connected to the end slider 32 of the support block 31 and a spring 33 for pushing the support block out of the support groove 34 are also provided in the support groove 34. A protrusion 36 for limiting the end slider 32 from escaping from the slide groove is provided at the end of the slide groove 35, thereby ensuring that the support block 31 will not escaping from the support groove 34. The top surface of the support block 31 extending out of the support groove 34 is also provided with an inclined sliding surface 36. The inclined sliding surfaces 36 of the multiple groups of elastic support groups 30 are distributed in a flared shape toward the top. At this point, after the copper body falls, it can first fall on the inclined sliding surface 36 of the support block 31 to achieve a rigid collision, avoiding direct impact on the light guide plate body 5, and then the driving end pressure rod 14 of the pressure cylinder 13 passes through the positioning cavity 16 and the through-hole 7 to slowly press the copper body 6 on the inclined sliding surface 36. The copper body 6 descends and presses the support block 31 to compress the spring 33 until the support block 31 extends into the support groove 34, and the copper body 6 contacts the light guide plate body. The copper body 6 under high temperature can soften the positioning hole 12 of the light guide plate body 5 until the copper body 6 is completely integrated into the positioning hole 12.

[0023] Linear racks 26 are arranged on both sides of the carrier plate 4, and each set of racks 26 is meshed with two sets of gears 27. The two sets of gears 27 corresponding to each set of racks 26 are respectively distributed at the inlet end 10 and the outlet end 11 of the hot melt assembly box 2, and are driven to rotate by a rotary motor 28 installed outside the hot melt assembly box 2. When the box door at the inlet end 10 is opened, the carrier plate 4 can slide into the hot melt assembly box 2 with the positioned light guide plate body 5 through the inlet end 10, and the two sets of gears 27 on both sides of the carrier plate 4 near the inlet end 10 are aligned. , under the synchronous drive of the two sets of gears 27, it completely enters the hot melt assembly box 2 along a straight line, and meshes with the other two sets of gears 27 when approaching the outlet end 11, until the positioning hole 12 on the light guide plate body 5 on it moves to the through opening 7 and stops moving. After the press-fitting is completed, the box door of the outlet end 11 can be opened, and the two sets of gears 27 near the outlet end 11 can synchronously drive the carrier plate 4 to guide and slide into the cooling box 3. At the same time, the inlet end 10 can also simultaneously load the next set of carrier plates 4, so as to complete the batch production operation.

[0024] The carrier board 4 is provided with a socket, in which a positioning rod 29 for circumferentially positioning the light guide plate body 5 is inserted. At this point, the positioning rod 29 group is inserted and installed in the socket to form a positioning for the light guide plate body 5 on the carrier board 4. The opening position of this socket needs to ensure that after the light guide plate body 5 is positioned, the carrier plate moves with the light guide plate body 5 in a straight line to a certain distance, so that the positioning hole 12 on the light guide plate body 5 can be exactly located below the through-opening 7. When the size of the light guide plate body changes, the position of the socket can be re-adjusted.
