Description

Technical Field

[0001] This invention relates to a mechanical manufacturing device, and more specifically, to an adhesive bonding machine that applies adhesive by heating it through a flow guide. Background Technology

[0002] With the development of industrial technology, modern industrial technology has become increasingly sophisticated, especially in the field of automotive materials manufacturing. Due to the large demand for automobiles, the sheet metal used in automobile manufacturing needs to be mass-produced in an engineered manner. Moreover, adhesives need to be applied to the sheet metal during assembly. Adhesives are volatile, and workers exposed to polluted air for extended periods can suffer damage to their lungs and skin. Currently, the market method for heating the adhesive in the pores of the sheet metal surface is to directly heat the sheet metal in the air using a heating rod. Although this method can heat and bond the sheet metal, indirect heating cannot precisely control the heating temperature, resulting in a significant waste of energy. Furthermore, due to the large temperature difference between winter and summer, the actual heating temperature cannot be controlled. During heating, the escaping air causes workers to inhale the volatile adhesive more rapidly. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an adhesive bonding device that heats the adhesive through a closed air duct.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a heavy-duty truck fairing adhesive bonding device, comprising a frame, an electrical control cabinet, a plasma controller, a pressing mechanism, a bearing mechanism, an adhesive spraying mechanism, and an adhesive melting mechanism. An mounting plate is provided on the top of the frame. The pressing mechanism is located at the top of the frame and includes an upper mold and a flipping mechanism. The bearing mechanism is located at the bottom of the frame and includes a lower mold and a lower mold base. The adhesive spraying mechanism is located on the side wall of the frame and is a robotic arm. The adhesive melting mechanism includes a fan, a heating module, and an air duct.

[0005] The invention is further configured such that: the heating module is mounted on the fan; the air duct includes the air duct body, the air inlet and the air outlet; an air inlet pipe is provided between the fan and the air inlet; an air inlet temperature sensor is provided inside the air inlet pipe; and a temperature and pressure sensor is provided inside the air duct body.

[0006] The present invention is further configured such that: the supporting mechanism includes a lower mold base frame and a lower mold disposed at the bottom of the frame, the lower mold is fixed to the lower mold base frame by screws, the air duct is fixed to the lower mold base frame by connecting columns, and the lower mold base frame is provided with limit holes.

[0007] The invention is further configured such that: the robotic arm is a six-axis robot, the six-axis robot is fixed to the side wall of the frame by screws, the end effector of the six-axis robot is equipped with a glue gun and a plasma head, the plasma head is used to clean the surface of the substrate to be processed, and the plasma head is wirelessly connected to the plasma controller.

[0008] The invention is further configured such that: the pressing mechanism includes a lifting cylinder, a tilting cylinder, a hydraulic station and an upper mold, the lifting cylinder and the tilting cylinder located at the top of the frame are fixed to the upper mold by screws, and the hydraulic station is fixed to the top of the frame by screws.

[0009] The present invention is further configured as follows: the direction of the air duct body is defined as the X direction, the width direction of the air duct body is defined as the Y direction, the thickness direction of the air duct body is defined as the Z direction, the air inlet pipe is set in the X direction, a plurality of air inlet temperature sensors are set inside the air inlet pipe, a through semi-cylindrical groove is set on the air duct body, the air inlet is an "L" shaped pipe, one end of the air inlet is set in the Y direction and the air inlet penetrates the interior of the air duct body, the other end of the air inlet is set in the Z direction and is connected to the bottom of the air duct body, and the air outlet and the temperature and pressure sensor are set on the semi-cylindrical groove.

[0010] The invention is further configured such that: the frame is a cubic frame fixedly connected by an outer sheet metal casing, a safety light curtain is provided on the vertical outer sheet metal casing, a safety fence is provided on the top perimeter of the main frame, and the pressing mechanism, the bearing mechanism, the glue spraying mechanism and the glue melting mechanism are electrically connected to the electrical control cabinet through wires.

[0011] The present invention is further configured as follows: a control method for a heavy-duty truck fairing adhesive bonding equipment, comprising the following steps:

[0012] S1. During the substrate installation stage, personnel operate the electrical control cabinet to control the flipping mechanism to flip the upper mold, and set the top plate substrate on the upper mold through the fixing device. Then, control the upper mold to flip and reset, and set the bottom plate substrate on the lower mold through the fixing device.

[0013] S2, during the pressing stage, personnel operate the electrical control cabinet to control the pressing mechanism to descend until the top substrate and the bottom substrate are bonded together.

[0014] S3. During the heating stage, the operator sets the preset heating temperature H1, the warning temperature H2, and the preset heating time T. The fan and heating module are started. When the temperature sensor detects that the temperature reaches the H value, the six-axis robot injects adhesive into the grooves on the surface of the substrate. The hot air generated by the heating module enters the pipe through the air inlets on the air duct body. The hot air flows in the chamber to heat the substrate and the hot melt adhesive inside the substrate.

[0015] S4. Cooling stage: When the hot air temperature reaches the warning temperature H2 or the heating time reaches the T value, the air outlet will automatically open to cool down. When the hot air temperature is lower than the warning temperature H2, the air outlet will automatically close and continue heating. After heating is completed, the plasma controller controls the six-axis robot to clean the substrate surface.

[0016] S5. During the reset phase, personnel operate the electrical control cabinet to control the upper mold to rise and reset, remove the composite board, and complete the bonding.

[0017] By adopting the above technical solution, the upper mold can rotate freely on the pressing mechanism through the mechanical control flipping mechanism, allowing the operator to load the material. When the operator fixes the substrate to be processed, the flipping mechanism returns to the horizontal level, and the pressing mechanism descends vertically to fit against the lower mold for pressing.

[0018] The temperature sensor installed in the melting mechanism can accurately control the air supply temperature, and the temperature and pressure sensor installed in the air duct can monitor the real-time hot air temperature and the gas pressure in the air duct. When the hot air accumulates and the temperature is too high or the gas pressure is too high, the air outlet can be opened automatically to exhaust the air, thereby ensuring that when the hot air heats the substrate and the melt adhesive in the air duct, the melt adhesive temperature will not be too high or too low due to seasonal temperature differences, thus failing to meet the processing standards.

[0019] The adhesive spraying unit can clean up residual molten adhesive on the substrate surface while spraying adhesive, ensuring that the substrate surface is clean and free of pollution, and also ensuring that the air is free of pollution. Attached Figure Description

[0025] Reference Figures 1 to 3 The present invention provides a further description of a heavy-duty truck fairing adhesive bonding device.

[0026] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0028] The following is combined with Figures 1 to 3 This invention provides a detailed description of a heavy-duty truck fairing adhesive bonding device, comprising a frame 1, an electrical control cabinet 2, a plasma controller 3, a pressing mechanism 4, a bearing mechanism 5, a glue spraying mechanism 6, and a glue melting mechanism 7. Each control mechanism mounted on the frame 1 is connected to the electrical control cabinet 2 according to electrical wiring requirements. The electrical control cabinet 2 houses switching devices, measuring instruments, protective electrical appliances, and auxiliary equipment. Located beside the frame 1, the electrical control cabinet ensures normal operation of the equipment and facilitates maintenance and repair. The frame 1 is a rectangular structure assembled from sheet metal, with sheet metal panels covering the left and right sides and the top surface. The sheet metal panels on the left and right sides ensure the equipment is waterproof and dustproof. The sheet metal panel on the top surface is used as a mounting plate 45 for mounting the bearing pressing mechanism 4. A safety fence 9 is installed around the top surface to protect maintenance personnel when the equipment requires repair.

[0029] The pressing mechanism 4 is installed through the sheet metal plate at the top of the frame 1. The pressing mechanism 4 includes a lifting cylinder 41, a tilting cylinder 42, a hydraulic station 43, a lifting frame, lifting slide rails, a lifting guide mechanism, an adsorption module, and an upper mold 44. The hydraulic station 43 is fixed to the mounting plate 45 with screws. The hydraulic station 43 provides hydraulic pressure to the pressing mechanism 4 when pressing the upper mold 44. Four lifting slide rails are provided, respectively located on the left and right side walls of the frame 1. The lifting frame is positioned at the four corners to match the lifting slide rails. The four lifting slide rails increase the stability of the lifting frame, ensuring the equipment is not easily damaged. The lifting slide rails also limit the track of the lifting frame, ensuring that it can... The substrate is accurately aligned. The upper mold 44 is movably connected to the lifting frame through a flipping mechanism. The lifting cylinder 41 is fixed to the upper mold 44 with screws and passes through the mounting plate 45. The flipping mechanism includes a rotating shaft and a connecting block. The rotating shaft is located on the longer side of the lifting frame. The rotating shaft and the upper mold 44 are rotatably connected through the connecting block. The surface of the upper mold 44 is provided with an adsorption module and a limiting hole. The adsorption module and the limiting hole are used to fix the substrate to be processed. The flipping cylinder 42 is fixed to the lifting frame with screws. The flipping mechanism can make the upper mold 44 rotate 90° along the rotating shaft, so that the upper mold 44 is perpendicular to the ground and faces the workers, which is convenient for the workers to install and fix the substrate to be processed.

[0030] The melting mechanism 7 includes a fan 71, a heating module 72, and an air duct 73. The fan 71 is located outside the frame 1. An air inlet pipe 74 is provided between the fan 71 and the air duct 73. The air duct 73 includes an air duct body 75, an air inlet 76, and an air outlet 77. The direction of the air duct body 75 is defined as the X direction, the width direction as the Y direction, and the thickness direction as the Z direction. The air inlet pipe 74 is located in the X direction and its length is the same as that of the air duct body 75. Multiple air inlets 76 are provided on the air inlet pipe 74 to ensure that the air duct 73 receives hot air uniformly at the same time when the fan 71 is working. The air inlet 76 is an "L"-shaped air inlet 76, with one end located in the Y direction and the other end located in the Z direction. The end located in the Z direction is connected to the air duct body 75. Several inlet air temperature sensors 78 are provided. The air duct body 75 is a through semi-cylindrical groove, which is used to store hot air for heating the substrate. An inlet air temperature and pressure monitor is installed in the air duct body 75 to monitor the real-time inlet air temperature. Several air outlets 77 are evenly arranged in the X direction on the air duct body 75. When the fan 71 is working, if the inlet air temperature monitor detects that the temperature or pressure inside the air duct body 75 is too high, the air outlets 77 can be automatically opened to reduce the pressure and temperature. When the substrate is bonded, the fan 71 continues to work, the heating module 72 is turned off, and cold air enters the air duct 73 to cool the composite board and accelerate the curing of the adhesive. An outlet air temperature sensor 78 is also installed at the output port of the fan 71. The setting of the three temperature sensors 78 can accurately control the temperature inside the melting adhesive mechanism 7, intelligently manage the temperature, and automatically introduce and exhaust air to ensure that energy is not wasted.

[0031] The supporting mechanism 5 includes a lower mold base frame 52 and a lower mold 51 set at the bottom of the frame 1. The lower mold base frame 52 is provided with several limiting holes. The lower mold 51 is fixed to the lower mold base frame 52 by screws. The air duct 73 is fixed to the lower mold base frame 52 by connecting columns. The supporting mechanism 5 is configured to support the lower mold 51 and the pressing mechanism 4.

[0032] The robotic arm of the glue spraying mechanism 6 is a six-axis robot 61. The six-axis robot 61 is fixed to the side wall of the frame 1 by screws. The end effector of the six-axis robot 61 is equipped with a glue gun 62 and a plasma head 31. The six-axis robot 61 can ensure all-round glue application. The plasma head 31 is used to clean the surface of the substrate to be processed. The plasma head 31 is wirelessly connected to the plasma controller 3, which is located on the side of the frame 1.

[0033] A control method for a heavy-duty truck fairing adhesive bonding equipment includes the following steps:

[0034] S1. During the substrate installation stage, personnel operate the electrical control cabinet to control the flipping mechanism to flip the upper mold, and set the top plate substrate on the upper mold through the fixing device. Then, control the upper mold to flip and reset, and set the bottom plate substrate on the lower mold through the fixing device.

[0035] S2, during the pressing stage, personnel operate the electrical control cabinet to control the pressing mechanism to descend until the top substrate and the bottom substrate are bonded together.

[0036] S3, Heating stage: Personnel set the preset heating temperature H1, warning temperature H2 and preset heating time T. The fan and heating module are started. When the temperature sensor detects that the temperature reaches the value of H1, the six-axis robot injects glue into the groove holes on the surface of the substrate. The hot air generated by the heating module enters the pipe through each air inlet on the air duct body. The hot air flows in the chamber to heat the substrate and the hot melt glue in the substrate.

[0037] S4. Cooling stage: When the hot air temperature reaches the warning temperature H2 or the heating time reaches the T value, the air outlet will automatically open to cool down. When the hot air temperature is lower than the warning temperature H2, the air outlet will automatically close and continue heating. After heating is completed, the plasma controller controls the six-axis robot to clean the substrate surface.

[0038] S5. During the reset phase, personnel operate the electrical control cabinet to control the upper mold to rise and reset, remove the composite board, and complete the bonding.

[0039] In step S1, the flipping mechanism is controlled by the electrical control cabinet to flip the upper mold so that it faces the worker. The worker fixes the top plate substrate to be processed on the upper mold using an adsorption device or a limiting clamp. Similarly, the bottom plate substrate can be fixed on the lower mold.

[0040] In step S2, the pressing mechanism is controlled by the electrical control cabinet to press the substrate. The pressing mechanism is vertically raised and lowered by the lifting guide mechanism to make the top plate substrate and the bottom plate substrate fit together. At the same time, the fan and heating module are started to preheat.

[0041] In step S3, the hot air temperature is set to H, the preset heating temperature is H1, the warning temperature is H2, and the preset heating time is T. The heating module heats until the hot air temperature H reaches the preset heating temperature H1. The heating module continues to heat to ensure that the hot air temperature H is higher than the preset heating temperature H1. The electrical control cabinet controls the six-axis robot to apply glue to the hole through the pre-set glue application data. Hot air enters the air duct body to heat the glue and accelerate the melting of the glue.

[0042] In step S4, after the heating time reaches the preset heating time T, the heating module is turned off, and the fan continues to blow cold air into the air duct to accelerate the cooling and fixing of the substrate board. At the same time, the six-axis robot cleans the surface of the composite board through the plasma head set on the end effector to ensure that the surface is free of contamination. When the hot air temperature H is greater than the warning temperature H2, the air outlet opens automatically to discharge excess hot air, thereby reducing the hot air temperature in the air duct and ensuring that the substrate is not damaged. When the hot air temperature H drops below the warning temperature H2, the air outlet closes to keep the air duct sealed and continue to heat the substrate.

[0043] In step S5, after the composite board is formed by bonding, the operator controls the electrical control cabinet to raise and reset the upper mold. The operator then removes the composite board, completing one processing cycle and preparing for the next processing task.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included within the protection scope of the present invention.
