[0034] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figure 1 As shown, in the silicon wafer production process, after the bonded silicon rods undergo wire cutting and debonding processes, the substrate and substrate plate used to bond the silicon rods need to be separated by boiling in water. In production, the substrate plates are mostly resin plates or glass plates. After separation, the substrate plates need to be cleaned of residual adhesive. The cleaned substrate plates will be reused to re-bond new substrate plates and silicon rods for subsequent silicon rod cutting.

[0037] This embodiment provides a water-boiling bonding production line for material plates and material seats, such as... Figure 2 , 3 As shown, the assembly includes a boiling device 1, a cooling device 2, a material seat drying device 3, and a bonding device 4 arranged sequentially. A manual adhesive scraping station 5 is provided between the boiling device and the cooling device. Each device station is connected by a conveyor line 6 for transport. The conveyor line can be a belt drive or a chain drive; this embodiment uses an existing double-speed conveyor line, a commonly used conveyor structure in existing production line technology, which is a roller conveyor chain. Therefore, its structure will not be described in detail. The boiling device 1 uses high-temperature water to boil the material, causing the adhesive between the material plate and the material seat to fail, thus separating the material seat from the material plate. The manual adhesive scraping station 5 is used to manually disassemble the material plate and remove residual adhesive from the material seat. Because the material seat is at a high temperature after boiling, naturally cooling it at room temperature would be too time-consuming. Therefore, after removing the residual adhesive, the material seat is sent to the cooling device 2 for cooling. After cooling, it is sent to the material seat drying device 3 for drying, so that the water on the material seat is dried. Finally, it is sent to the bonding device 4 for bonding the material seat to a new material plate. Downstream of the pasting device, a manual glue scraping station 7 is set up for manually scraping off excess glue and pasting wood grain paper. Due to space limitations, a rotating mechanism 8 can be installed on the conveyor line to change the conveying direction of the material seat. The structure of the rotating mechanism is as follows: Figure 20 The structure shown is an existing one and will not be described in detail here. Finally, the finished product with the material holder and material plate glued together flows out for use in silicon wafer cutting.

[0038] Both the boiling device 1 and the cooling device 2 have water on their material seats after discharge. Therefore, a water collection box is installed below the conveyor line between the boiling device and the cooling device, and a water collection box is installed below the conveyor line between the cooling device 2 and the material seat drying device 3.

[0039] like Figure 4 As shown, the boiling device 1 includes a boiling feeding module 11, a boiling module 12 and a first conveying module 13. The boiling feeding module 11 is located upstream (feeding side) of the boiling module 12 and is used to convey the material to be boiled. The first conveying module is located above the boiling module and is used to transport and pick up the material.

[0040] The boiling module 12 includes a first support 121, on which at least one water tank 122 is provided. Preferably, in this embodiment, the first support has six water tanks, each with its own heating element 1221. The heating element can be located on the side wall or bottom wall of the water tank. Figure 5 As shown, in this embodiment, the heating tube is located on the side wall of the water tank, and the side wall has a connection hole. The threaded connection part of the heating tube passes through the connection hole, and the nut 123 is fixed to the heating tube to fix the heating tube in the water tank. Each heating tube has a power of 12kw, and two tubes are used in one water tank, for a total of 24kw. The water tank has a capacity of 0.15 cubic meters. Theoretically, it takes 30 minutes to heat the water to 100 degrees.

[0041] The side wall of water tank 122 is equipped with a water inlet 1225, and the bottom of the water tank is equipped with a drain outlet. An inlet valve is installed at the water inlet, and a drain valve is installed at the drain outlet. The water inlets of each water tank are connected to the same inlet pipe, thus connecting the water tanks in series. The drain outlets are each connected to the same drain pipe. Each water tank's water inlet and drain outlet is equipped with a valve, meaning each water tank is independently configured and the water flow can be controlled individually. If one water tank fails, the others are unaffected, and each water tank can be cleaned individually. A filter screen 1227 is installed above the drain outlet to filter impurities after cleaning. The filter screen is configured as follows... Figure 6 As shown, the water tank has a "T"-shaped structure. Both the inlet and outlet are located in the lower vertical section. The inner wall of the lower vertical section has an installation groove 1228, and a filter screen outlet 1229 is located at a corresponding position on the side wall of the water tank. The filter screen is inserted into the installation groove through the filter screen outlet and can be removed directly from the filter screen outlet. A cap 1226 is provided at the filter screen outlet, which is snapped onto the side wall of the water tank or connected by bolts.

[0042] To facilitate the placement of the material holder, a material holder bracket 1222 is provided inside the water tank 122, as detailed below. Figure 5As shown, the material holder bracket includes a connecting part 12221 and a supporting part 12222. The connecting part overlaps the first bracket 121, and the supporting part extends into the water tank 122. The supporting part is 20-100mm away from the bottom of the horizontal tank, so that water covers all surfaces of the material holder, allowing the material holder to be fully boiled. The boiling effect is good, and the degumming effect between the material holder and the material plate is good. The material holders commonly used in production are those for the MB288 wire cutting machine and those for the PV500HD wire cutting machine. The size of the material holder bracket needs to ensure that it can accommodate larger material holders, that is, the material holder bracket is compatible with two material holder sizes. The size of the material holder bracket can be adapted to the actual production situation. This application does not impose specific restrictions on the size of the material holder bracket. In this embodiment, one material holder bracket can accommodate two material holders. The inner wall of the water tank 122 is also equipped with a level gauge 1223 and a temperature controller 1224. The temperature controller is used to monitor the temperature in the water tank. The heating tubes in the water tank are configured separately, and the temperature in each water tank can be controlled independently. The level gauge is used to monitor the water level in the tank, and the water temperature and level of each tank can be controlled independently. Each tank is equipped with a valve at the inlet and outlet, meaning that the tanks are independently configured and the water flow can be controlled independently. If one tank fails, the other tanks are not affected, and each tank can be cleaned individually.

[0043] like Figure 7 As shown, the water-boiling feeding module 11 includes a second support 111 and a conveyor line 6 mounted on the second support. The conveyor line can be a belt drive or a chain drive. In this embodiment, a chain drive is used, and an existing double-speed conveyor line is used. The double-speed conveyor line is a commonly used conveyor structure in existing production line technology. It is a roller conveyor chain, so its structure will not be described in detail.

[0044] A material dispensing sensor and a material dispensing cylinder are installed at one end of the conveyor line 6 near the water boiling module 12. The material dispensing sensor and the material dispensing cylinder are linked. The material dispensing sensor can be a photoelectric sensor or an ultrasonic sensor, etc. In this embodiment, a photoelectric sensor is used. The photoelectric sensor senses the presence or absence of the material seat by detecting changes in photoelectric signals, thereby controlling the lifting and retraction of the piston rod of the material dispensing cylinder. The material dispensing cylinder divides the conveyor line into two sections: a buffer section and a feeding section. With the material dispensing cylinder as the boundary, the feeding section is the part closer to the water tank, and the buffer section is the part farther away from the water tank.

[0045] like Figure 8 , 9As shown, the first handling module 13 includes a third support 131 and a connecting rod 132. A rack 1311 is mounted on the third support, positioned above the boiling module 12. A lifting gripping device 133 is mounted on one side of the connecting rod 132, and a bearing seat 1321 is mounted on the other side of the connecting rod 132. The bearing seat contains a bearing and a rotating shaft 1322. Gears 1323 are mounted at both ends of the rotating shaft, and these gears are connected to the rack via gear transmission, thereby driving the lifting gripping device to move left and right. The lifting gripping device 133 includes a cylinder 1331, a first connecting plate 1332, and a gripper 1333. In this embodiment, the connecting plate is L-shaped, with its vertical surface connected to one side of the connecting rod 132. The cylinder is mounted on the connecting plate, and its piston extends out of the horizontal surface of the connecting plate and connects to the gripper. To ensure gripping stability, a guide sleeve 13321 is provided on the connecting plate 1332, and a guide post 13331 is provided on the gripper 1333. The guide post is sleeved inside the guide sleeve and moves up and down within the guide sleeve under the drive of the cylinder piston. When the cylinder piston moves down, the gripper grabs the material seat; when the piston moves up, the gear and rack drive moves the material seat to the corresponding water tank 122; when the piston moves down, it places the material seat in the corresponding water tank. The left and right movement of the gear and rack, along with the up and down movement of the gripper driven by the cylinder, realizes the loading and unloading of materials.

[0046] The material base to be boiled is placed on the buffer section of conveyor line 6. The conveyor line transports the material base to the loading section. The material distribution sensor senses that the material base has moved to the loading section. The piston of the material distribution cylinder is lifted to prevent the material base in the buffer section from moving forward. The piston of cylinder 1331 of the first handling module 13 moves down. The gripper 1333 grabs the material base. The piston drives the material base to move up. The gear and rack drive drives the material base to move to the left to the corresponding water tank 122. The piston moves down to place the material base on the corresponding material base bracket 1222. This process is repeated until the water tank is filled with material bases. Hot water can be preheated in the water tank to boil the material bases. After the material bases stay in the water tank for 15-20 minutes, the first handling module repeats the action to remove the material bases and put them on the conveyor line. The conveyor line sends the material bases to the manual glue scraping station to remove the material plate and scrape the glue. The upstream conveyor line of the manual glue scraping station is also equipped with a material distribution sensor and a material distribution cylinder. The material distribution sensor and the material distribution cylinder are linked to divide the conveyor line into two sections: a buffer section and a feeding section.

[0047] The cooling device 2 includes a cooling module 21, a heat exchange module 22, and a second conveying module 23. The second conveying module is located above the cooling module and is used to convey the material seat to realize loading and unloading. The heat exchange module is connected to the cooling module and performs heat exchange with the cooling module to realize the recycling of cold water in the cooling module.

[0048] like Figure 10As shown, the cooling module 21 includes a fourth support 211, on which a cooling pool 212 is provided for holding cooling water. The bottom surface of the cooling pool is inclined at an angle of 5 to 20 degrees. A drain outlet is provided at the lower end of the cooling pool, and a water inlet is provided at the higher end. This arrangement allows the cold water entering through the water inlet to flow from the higher end to the lower end, effectively cooling the material seat inside the pool.

[0049] The cooling pool 212 is equipped with a material holder support 2121, which includes a connecting part 21211 and a supporting part 21212. The connecting part overlaps with the fourth support 211, and the supporting part extends into the cooling pool. The supporting part 21212 is 20-100mm away from the bottom surface of the cooling pool 212, allowing cold water to cover all surfaces of the material holder, making the cooling more thorough and improving the cooling speed of the material holder. The material holders commonly used in production are those for the MB288 wire cutting machine and the PV500HD wire cutting machine. The size of the material holder support needs to be able to accommodate larger material holders, that is, the material holder support is compatible with two material holder sizes. The size of the material holder support can be adapted according to the actual production situation. This application does not impose specific restrictions on the size of the material holder support. The inner wall of the cooling pool is also equipped with a level gauge 2122 and a temperature controller 2123. The temperature controller is used to monitor the temperature in the cooling pool, and the level gauge is used to monitor the water level in the pool.

[0050] A filter screen 2124 is installed above the drain outlet to filter the water at the drain outlet, preventing impurities from entering the heat exchanger and affecting its service life. The filter screen is set as follows: Figure 11 As shown, specifically: the cooling pool at the drain outlet has a downward-facing vertical groove. The inner wall of the vertical groove has an installation groove 2125, and the corresponding position on the outer wall of the vertical groove has a filter screen outlet 2126. The filter screen is inserted into the installation groove through the filter screen outlet, and can be pulled out directly from the filter screen outlet when removed. A cap 2127 is provided at the filter screen outlet, and the cap is snapped onto the side wall of the water tank or connected by bolts.

[0051] like Figure 12As shown, the heat exchange module 22 includes a heat exchanger 221, a first valve 222, and a second valve 223. The drain outlet is connected to the inlet of the heat exchanger 221 via a first branch pipe 2211 and a second branch pipe 2212. The outlet of the heat exchanger is connected to the inlet of the cooling pool via a third branch pipe 2213 and a fourth branch pipe 2214. The first branch pipe 2211 is connected to the inlet of the first valve 222, the second branch pipe 2212 is connected to the first outlet of the first valve 222, and the second outlet of the first valve 222 is connected to a drain pipe 2215, which is used to drain water from the pool. The third branch pipe 2213 is connected to the first inlet of the second valve 223, the outlet of the second valve 223 is connected to the fourth branch pipe 2214, and the second inlet of the second valve 223 is connected to a water inlet pipe 2216, which is connected to an external water source to supply water to the cold water pool. Water from the cooling pool drain enters the heat exchanger, is cooled by the heat exchanger, and then is connected to the inlet, completing the recycling of water in the cooling pool and saving water resources.

[0052] The structure of the second handling module 23 is the same as that of the first handling module 13, and will not be described in detail here. When the cylinder piston moves down, the gripper picks up the material seat. When the piston moves up, the gear and rack drive moves the material seat to the corresponding material seat bracket. When the piston moves down, the material seat is placed on the corresponding material seat bracket. The left and right movement of the gear and rack and the up and down movement of the gripper driven by the cylinder realize the loading and unloading of materials.

[0053] In the second handling module, the piston of the cylinder moves downward, the gripper picks up the material seat, the piston drives the material seat upward, and the gear and rack drive the material seat to move to the left to the corresponding material seat support. The piston moves downward and places the material seat on the corresponding material seat support. This process is repeated until the pool is filled with material seats. The material seats are then placed in a cold water pool to cool. Once the material seat temperature is below 30 degrees Celsius, the second handling module removes the material seats for subsequent pasting of new boards. The conveyor line at the loading end of the cooling pool is also equipped with a material distribution sensor and a material distribution cylinder. The material distribution sensor and the material distribution cylinder are linked to divide the conveyor line into a buffer section and a loading section.

[0054] like Figure 19 As shown, the material drying device 3 is an air knife, located above the conveyor line 6. The air knife is an instrument used for cleaning, air-drying, and drying precision components. Made of stainless steel, it is driven by a high-pressure centrifugal fan to deliver uniform and powerful hot air, thereby achieving the purpose of drying and cleaning. In this embodiment, a commercially available air knife is used to remove moisture and residual dirt from the material base for subsequent pasting of new material plates. The conveyor line at the air knife location is also equipped with a material distribution sensor and a material distribution cylinder. The material distribution sensor and cylinder are linked, dividing the conveyor line into a buffer section and a drying section, allowing the material base to dry sequentially.

[0055] The bonding device 4 includes a dispensing module 41, a material plate loading module 42, a first counterweight transport module 43, a second counterweight transport module 44, a material plate hopper 49, a fifth bracket 46, and a sixth bracket 47. The material plate loading module and the first counterweight transport module are located downstream of the dispensing module, the second counterweight transport module is located downstream of the first counterweight transport module, and the material plate hopper is located on one side of the material plate loading module. The conveyor line 6 runs through all the mechanisms. The fifth and sixth supports are both located above the conveyor line. The fifth support 46 has a dispensing module 41 on the side closest to the upstream of the conveyor line, which is used to apply glue to the upper surface of the material seat. The fifth support 46 has a material plate loading module 42 and a first counterweight handling module 43 on the side furthest from the upstream of the conveyor line. The material plate loading module is used to place the material plate on the material seat for bonding. The first counterweight handling module is used to place the counterweight on the material plate 48 to facilitate subsequent curing and realize the automation of bonding between the material plate and the material seat. The sixth support 47 has a second counterweight handling module 44 on the side closest to the material plate loading module 42, which is used to remove the counterweight from the cured material plate. In this embodiment, the material loading module 42 and the first counterweight handling module 43 are located at the same workstation. The dispensing module and the material loading module on the conveyor line are each equipped with a dispensing sensor and a dispensing cylinder at corresponding positions. The dispensing sensors and cylinders are linked to divide the conveyor line into a buffer section and a dispensing section, and then into a material loading and counterweight pressing section, allowing the material holder to be dispensed with glue, and the material loading and counterweight pressing operations to proceed sequentially. All dispensing sensors and cylinders are connected to the PCL control system, which receives signals from the dispensing sensors to control the extension and retraction of the dispensing cylinder pistons.

[0056] like Figure 13As shown, the dispensing module 41 includes a first up-and-down moving mechanism 411 for moving the dispensing head up and down; a first left-and-right moving mechanism 412 for moving the dispensing head left and right; and a first front-and-back moving mechanism 413 for moving the dispensing head back and forth. The first up-and-down moving mechanism has a dispensing head that is conical in shape and has an internal through-hole for adhesive to flow out. The dispensing head and adhesive are connected via a glue tube. The first front-and-back moving mechanism 413 is located on the side of the fifth bracket 46 near the loading end of the conveyor line. The first left-and-right moving mechanism 412 is located on the first front-and-back moving mechanism 413, and the first up-and-down moving mechanism 411 is located on the first left-and-right moving mechanism 412. The first forward and backward moving mechanism 413 and / or the first left and right moving mechanism 412 can be implemented by hydraulic mechanisms, motor-driven belt transmission mechanisms, motor-driven chain transmission mechanisms, or motor-driven lead screw and lead screw nut transmission mechanisms, etc. In this embodiment, belt transmission is selected. Specifically, the left side of the fifth bracket 46 is provided with a first mounting plate 461, and the first mounting plate is provided with two pulleys, one in front and one behind. A conveyor belt is provided on the pulleys. A motor is mounted on the first mounting plate, and the output shaft of the motor is connected to one of the pulleys. The rotation of the motor drives the pulley to rotate, and the rotation of the pulley drives the conveyor belt to move forward and backward. The conveyor belt drives the structure on the conveyor belt to move forward and backward. The front and rear conveyor belts are provided with second connecting plates 46. 2. The second connecting plate is L-shaped. The vertical part of the second connecting plate is fixed to the conveyor belt. The horizontal part of the second connecting plate is equipped with a second mounting plate 463. The second mounting plate is equipped with two pulleys, one on the left and one on the right. The pulleys are equipped with the conveyor belt. A motor is mounted on the second mounting plate. The output shaft of the motor is connected to one of the pulleys. The rotation of the motor drives the pulley to rotate. The rotation of the pulley drives the conveyor belt to move left and right. The conveyor belt drives the structure on the conveyor belt to move left and right. The left and right conveyor belts are equipped with a third mounting plate 464. The third mounting plate is equipped with a cylinder arranged in the vertical direction. The piston of the cylinder extends out of the third mounting plate and is connected to the dispensing head. The vertical extension and retraction of the cylinder piston drives the dispensing head to move up and down.

[0057] like Figure 14As shown, a second forward and backward moving mechanism 421 is provided on the side of the fifth bracket 46 away from the feeding end of the conveyor line. In this embodiment, a second forward and backward moving mechanism is provided on the right side of the fifth bracket 46 to realize the forward and backward movement of the material plate feeding module 42 and the first counterweight handling module 43. Similarly, this forward and backward movement can be realized by hydraulic mechanism, motor-driven belt transmission mechanism, motor-driven chain transmission mechanism, or motor-driven screw and screw nut transmission mechanism, etc. In this embodiment, chain transmission is preferred. Specifically, a fourth mounting plate 465 is provided on the right side of the fifth bracket 46. A sprocket is provided on the fourth mounting plate in the forward and backward direction. A chain is provided on the sprocket. A motor is mounted on the fourth mounting plate. The rotation of the motor drives the sprocket to rotate. The rotation of the sprocket drives the chain to move forward and backward. The forward and backward movement of the chain drives the structure provided on the chain to move forward and backward. A first fixing plate 466 is fixed on the chain. The material plate feeding module 42 and the first counterweight handling module 43 are provided on the first fixing plate. Specifically, as shown in the figure... Figure 15 As shown, the material loading module 42 includes a first cylinder 422, a third connecting plate 423, and a first gripper 424. The third connecting plate is mounted on the first fixed plate 466. In this embodiment, the third connecting plate is bolted to the first fixed plate. The third connecting plate is L-shaped, with its vertical surface connected to the first fixed plate. The first cylinder is mounted on the horizontal surface of the third connecting plate, and its piston extends out of the horizontal surface and connects to the first gripper. To ensure gripping stability, the third connecting plate 423 has a first guide sleeve 4231, and the first gripper 424 has a first guide post 4241. The first guide post is fitted inside the first guide sleeve and moves up and down within the first guide sleeve under the action of the first cylinder piston. In this embodiment, four suction cups 4242 are evenly distributed on the lower surface of the first gripper. Since the material plate is a glass or resin plate, the suction cups on the lower surface of the gripper will pick up the material plate and place it on the material base.

[0058] like Figure 16 As shown, the first counterweight handling module 43 includes a second cylinder 431, a fourth connecting plate 432, and a second gripper 433. The fourth connecting plate is mounted on the first fixed plate 466. In this embodiment, the fourth connecting plate is bolted to the first fixed plate. The fourth connecting plate is L-shaped, with its vertical surface connected to the first fixed plate. The second cylinder is mounted on the horizontal surface of the fourth connecting plate, and its piston extends out of the horizontal surface and connects to the second gripper. To ensure gripping stability, a second guide sleeve 4321 is mounted on the fourth connecting plate, and a second guide post 4331 is mounted on the second gripper. The second guide post is fitted inside the second guide sleeve and moves up and down within the second guide sleeve under the action of the second cylinder piston. In this embodiment, two cylinders are evenly distributed on the lower surface of the second gripper. The pistons of the cylinders are connected to the grippers, which are used to grip the counterweight.

[0059] In this embodiment, both the material loading module 42 and the first counterweight conveying module 43 are mounted on the first fixed plate 466 and are fixed relative to the first fixed plate in the front-back direction, thereby realizing the linkage between the material loading module and the first counterweight conveying module in the front-back direction. The motor drives the chain to move back and forth, the chain drives the first fixed plate to move back and forth, and the first fixed plate drives the material loading module and the first counterweight conveying module to move back and forth together. When the material loading module moves forward to pick up the material plate, the first counterweight conveying module also moves forward to place the counterweight on the material plate that has been glued on at the current workstation. The operation of pressing the counterweight is completed at the same time as picking up the material plate, which greatly improves the production efficiency.

[0060] Material hopper, used to hold material hoppers, such as Figure 17As shown, the material plate hopper 49 is located on the side of the conveyor line 6 near the material plate loading module 42. Since there are various sizes and specifications of material seats in actual production, and corresponding material plate specifications are also varied, material plates and material seats of corresponding specifications are bonded during bonding. To accommodate bonding of material seats and material plates of various specifications using the same device, the material plate hopper 49 is equipped with a partition 491. The partition divides the material plate hopper into multiple sub-hoppers, each holding material plates of different specifications. Commonly used material seats in production are the MB288 wire cutting machine material seat and the PV500HD wire cutting machine material seat, corresponding to two different specifications of material plates. In this embodiment, a partition is used to divide the material plate hopper into two sub-hoppers. This application does not limit the number of partitions or the number of sub-hoppers; adjustments can be made according to actual production needs. The bottom of the material hopper is equipped with a reciprocating moving mechanism 492 for moving the material hopper to move the material hopper of the required specifications to below the material hopper loading module. The distribution bin is equipped with a lifting mechanism 493 for lifting the material hopper to the outlet for the first gripper to pick up. Both the reciprocating moving mechanism and the lifting mechanism can be implemented by hydraulic mechanisms, belt drive mechanisms, chain drive mechanisms, or screw and nut drive mechanisms, etc. In this embodiment, a screw and nut mechanism is used to achieve the reciprocating motion and lifting motion. Specifically, a seventh support 4921 is provided on the side of the conveyor line near the material hopper loading module. The seventh support has a screw and a screw nut that cooperate with each other. The material hopper is fixed on the screw and nut. The screw is parallel to the conveyor line. A motor is installed on the seventh support, and the output shaft of the motor is connected to the screw. The motor drives the screw to rotate, and the screw drives the screw nut to reciprocate. The material hopper fixed on the screw and nut reciprocates accordingly. The side of the distribution bin... A lead screw is installed on the wall, and a motor is installed inside the material distribution bin. The motor output shaft is connected to the lead screw, and a lead screw nut is installed on the lead screw. At least one cylinder is installed on the lead screw nut, and the piston of the cylinder is connected to a clamping plate. When the motor rotates, it drives the lead screw to rotate, and the lead screw drives the lead screw nut and the cylinder to move downwards. The moving belt corresponds to the area below the material plate. The piston of the cylinder extends to make the clamping plate hold the material plate. When the motor reverses, the lead screw drives the material plate to rise. A through-beam photoelectric sensor 494 is installed on the top of the material distribution bin, including a transmitter and a receiver. The transmitter emits red light or infrared light, and the receiver receives the light when an object passes by and cuts off the light, and then outputs a signal. When the material plate rises to the photoelectric sensor, the photoelectric sensor outputs a signal to control the motor to stop, and the lifting action stops. A cylinder 495 can be installed on the top of the material distribution bin corresponding to one long side and one short side of the material plate, respectively, for adjusting and positioning the long side and short side of the material plate, so as to facilitate the material plate feeding module 42 to pick up the material plate.

[0061] A counterweight is added to the bonded material base plate to strengthen the bond between the material base and the material plate. The counterweight is typically removed 10-25 minutes after addition. A sixth support 47 is located above the conveyor line. A third forward / backward moving mechanism 471 is located on the side of the sixth support near the material plate loading module 42. A second counterweight handling module 44 is mounted on the third forward / backward moving mechanism to remove the counterweight from the material plate. The third forward / backward moving mechanism can also be implemented using a hydraulic mechanism, a motor-driven belt drive mechanism, a motor-driven chain drive mechanism, or a motor-driven screw and screw nut drive mechanism. In this preferred embodiment, the mechanism is similar to that of the aforementioned second forward / backward moving mechanism 421, both using chain drive. The only difference is that the mounting plate on the conveyor chain only has the second counterweight handling module 44 and not the material plate loading module 42; the rest of the structure is the same. The structure of the second counterweight handling module 44 is the same as that of the first counterweight handling module 43, and will not be described in detail here. Figure 18 As shown, a counterweight return line 61 is provided on the side of the conveyor line 6 near the first counterweight handling module 43. The counterweight return line 61 is similar to the conveyor line 6 in that it adopts belt drive or chain drive. The counterweight return line is arranged parallel to the conveyor line and is used to transport the removed counterweight back to the first counterweight handling module for counterweight placement.

[0062] The conveyor line transports the material base to the area below the dispensing module. The dispensing module moves downwards, left and right, forwards and backwards, and the dispensing head contacts the surface of the material base to apply adhesive to the upper surface of the material base. The material base is then moved forward to the loading plate station. The reciprocating movement mechanism of the material plate hopper moves the corresponding material bin to the corresponding gripping position of the loading plate module. The lifting mechanism lifts the material plate, and the second forward and backward movement mechanism moves the loading plate module and the first counterweight transport module forward. The suction cup on the first gripper picks up the material plate, and the second forward and backward movement mechanism moves the loading plate module and the first counterweight transport module backward. The loading plate module places the material plate on the material base, and the second gripper of the first counterweight transport module picks up the counterweight. The loading plate module and the first configuration transport module move forward. While placing the counterweight, the first gripper picks up another material plate for subsequent use. After 15 minutes of adding the counterweight, the second counterweight transport module removes the counterweight and places it on the counterweight return line to transport the counterweight back to the placement location.

[0063] After the material base plate is pasted, excess glue is scraped off and wood grain paper is pasted on. During conveying, a rotating lifting device can be installed on the conveyor line to change the direction of transport to adapt to space constraints.

[0064] This embodiment provides a water-boiling bonding production line for material plates and bases, which has a high degree of automation. The multiple processes of separating and bonding the material plates and bases are continuously and mechanically operated on the production line, without the need for a large number of dedicated personnel for manual operation. It has a low error rate, high separation and bonding efficiency, and a high product qualification rate.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
