Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to a glue application assembly and a glue application device for circuit boards. Background Technology

[0002] In controller manufacturing, applying adhesive to the solder joints of the motor board provides physical protection for the solder joints, preventing damage caused by mechanical impact or wear. Currently, there are several methods for applying solder joint protective adhesive, including coating, spraying, selective coating, dispensing, and immersion.

[0003] The coating method involves manually applying the adhesive to the solder joint surface, but manual operation has issues with coating thickness and labor consumption. The spraying method cannot accurately select the application location, leading to adhesive waste and affecting product quality.

[0004] The spraying method uses spraying equipment to spray protective adhesive onto the solder joints in a mist form. This method can achieve uniform coverage over a large area, but it cannot precisely select small areas for coating.

[0005] Selective coating requires the use of templates or masks to control the coating area of ​​the protective adhesive. This method can precisely control the coating position, but it is complex to operate and affects production efficiency.

[0006] The dispensing method allows for precise control of the amount and location of adhesive used through dispensing equipment, but it suffers from low coating efficiency.

[0007] The dip-coating method involves immersing the entire circuit board or component in a container of protective adhesive, then removing it and draining off any excess adhesive. This method is suitable for components that require comprehensive protection.

[0008] It is evident that the current method of applying adhesive to the solder joints of motor boards still cannot adequately balance the issues of precision, efficiency, and cost. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of the prior art by providing a glue application component that can selectively or over a large area apply glue to boards, and features high glue application precision, fast speed, simple structure and easy operation.

[0010] To achieve one of the above objectives, this utility model provides the following technical solution:

[0011] Provides an adhesive application assembly, including

[0012] The brush needle is provided with bristles arranged in a straight line, and the bristles can brush the adhesive surface of the piece to be coated.

[0013] The bristles of this brush needle are arranged in a straight line, so that the entire brush surface has both long and narrow sides, making it easy to control the area of ​​adhesive application. Specifically, the brush needle is a rectangular flat brush.

[0014] The glue inlet channel is connected to the brush needle and supplies glue to the brush needle.

[0015] One end of the brush needle is equipped with brush bristles, and the other end is equipped with a glue inlet. This glue inlet is used to connect with the glue inlet channel to facilitate the supply of glue to the brush bristles.

[0016] A rotating mechanism is provided, wherein the brush needle is mounted on the rotating end of the rotating mechanism, and the rotating mechanism drives the brush needle to rotate at a set angle on the adhesive surface.

[0017] This rotating mechanism drives the brush needle to rotate as well. When the brush needle rotates 360°, it can apply glue to a large area of ​​the board surface. When it rotates 15°, it can apply glue to only the area within that 15° range, effectively balancing both large and small area glue application. Furthermore, by moving the rotating mechanism to move the brush needle, it can selectively apply glue to different locations, further improving the flexibility of the glue application process.

[0018] In some embodiments, the rotating mechanism includes a motor, with one end of the brush needle connected to the rotating shaft of the motor, and the rotating mechanism further includes a flange and a fork.

[0019] One end of the flange is connected to the rotating shaft of the motor, and the other end of the flange is fixed to the pull fork. The brush needle is connected to the pull fork.

[0020] The flange is driven to rotate by a motor, preferably a servo motor, which in turn drives the fork to rotate. That is, the brush needle is driven to rotate by the rotating shaft of the motor.

[0021] In some embodiments, the brush needle is connected to a dispensing valve connected to the glue inlet channel, the dispensing valve and the brush bristles are located at opposite ends of the brush needle, and the brush needle is connected to the fork via the dispensing valve.

[0022] This dispensing valve is used to control the dispensing status of the glue inlet channel. The dispensing valve is connected to the fork, making the whole structure more compact.

[0023] In some embodiments, a bearing is also included, which is fixed on a mounting plate. The dispensing valve is fitted with a rotating bushing that is adapted to the inner ring of the bearing in the bearing housing. The dispensing valve is positioned via the mounting plate.

[0024] A rotating bushing is provided on the outer periphery of the dispensing valve. This rotating bushing is adapted to the inner ring of the bearing in the bearing housing, so that the dispensing valve can rotate more stably, thereby allowing the brush needle to rotate more stably as well.

[0025] The beneficial effects of this adhesive application component are as follows:

[0026] The adhesive application assembly of this invention provides adhesive to the brush needles via an adhesive inlet pipe, ensuring continuous adhesive application. The brush needles have linearly arranged bristles. Driven by a rotating mechanism, the brush needles can either rotate the entire brush to apply adhesive to a large area of ​​the board surface, or rotate only at a set angle to apply adhesive to small areas or narrow locations. This allows for precise control of the application area, improving flexibility and accuracy while effectively balancing precision and effectiveness. Furthermore, the rotating adhesive application ensures even application of the adhesive, preventing waste.

[0027] To achieve the second objective mentioned above, this utility model provides the following technical solution:

[0028] A panel gluing device is provided, comprising at least two stations, each station including the aforementioned gluing components, wherein the operation processes of at least two stations are performed alternately.

[0029] This glue application assembly accurately and quickly applies glue to the boards at the workstations. At the same time, because the two workstations can move alternately, when a single person controls the production line, while some workstations are applying glue, the glue application quality of the products at the other workstation that has finished applying glue can be identified, avoiding production line stoppages and effectively improving production efficiency.

[0030] In some embodiments, a plate clamp for positioning the plate to be glued is provided below the glue application assembly. The glue application assembly is fixed on a multi-axis module, and the multi-axis module drives the glue application assembly to move in multiple dimensions and apply glue to the plate to be glued.

[0031] The function of this panel fixture is to position the panel so that the glue application assembly can apply glue to the entire stable panel. At the same time, since the glue application assembly is fixed on the multi-axis module, the multi-axis module can drive the glue application assembly to move in the X, Y, and Z axes, so that the brush assembly can apply glue to each surface of the panel.

[0032] In some embodiments, the plate clamp includes a first support plate and a second support plate.

[0033] The first support plate and the second support plate are vertically arranged with their inner surfaces facing each other. The two ends of the piece to be glued are respectively fixedly mounted on the top of the first support plate and the top of the second support plate.

[0034] The vertical arrangement of the first and second support plates, with their surfaces facing each other, serves two purposes: firstly, it supports the parts to be glued, facilitating the application of glue; secondly, the long sides of the plates can better contact the parts, thus enhancing the support; and thirdly, the support plates prevent spilled glue from splashing out, protecting the entire system.

[0035] In some embodiments, a cylinder is provided on the outer surface of the first support plate and / or the outer surface of the second support plate.

[0036] The piston rod of the cylinder points to the top of the support plate and is connected to a pressure block. The piston rod drives the pressure block to press against the end of the piece of material to be coated with adhesive.

[0037] Since the cylinder is located on the outer side of the support plate, the pressure block can be moved up and down by the extension and retraction of the piston rod of the cylinder. When the pressure block moves upward, it moves away from the glue-to-be-applied piece, and the glue-to-be-applied piece can be picked up. When the pressure block moves downward, it can press the glue-to-be-applied piece firmly, fix the glue-to-be-applied piece, and apply glue evenly.

[0038] In some embodiments, the top inner side surface of the first support plate and / or the top inner side surface of the second support plate have an L-shaped notch, and the end of the piece to be coated with adhesive is mounted on the L-shaped notch.

[0039] The L-shaped notch can limit the end of the part to be glued, preventing the part from shifting.

[0040] In some embodiments, one end of the pressure block is connected to the piston rod, and the other end of the pressure block is bent downward at 90° and can press against the end of the adhesive plate to be brushed on the L-shaped notch.

[0041] The pressure block presses the sheet to be glued down by its bent end, which can more stably fix the two ends of the sheet.

[0042] In some embodiments, the bottom surface of the pressing block is provided with a buffer pad, and the pressing block presses against the end of the piece of adhesive to be brushed through the buffer pad.

[0043] This cushioning pad prevents the parts to be coated with adhesive from being scratched.

[0044] In some embodiments, a wire baffle is also included, with both ends of the wire baffle fixed on the same side of the first support plate and the second support plate, respectively. When applying glue, the wires of the board to be glued are blocked by the wire baffle on the outside directly below the board to be glued.

[0045] When applying adhesive, there is a problem of adhesive dripping down. The parts to be glued are usually connected to wire harnesses. If the adhesive drips onto the wire harnesses, it will affect the product quality. To address this, the wire harnesses are placed outside the wire baffle. The wire baffle can prevent the wire harnesses from falling under the parts to be glued and thus contaminating the wire harnesses with adhesive.

[0046] In some embodiments, the plate clamp is mounted on the slide assembly, one end of the slide assembly is a loading / unloading station, and the other end of the slide assembly is located below the glue application assembly and is also a glue application station.

[0047] By setting the panel fixture on the slide assembly, the panel fixture can move along the length of the slide assembly, thereby avoiding the obstruction of the glue application assembly at the glue application station when inspecting the glue application quality.

[0048] In some embodiments, a controller is also included, which is connected to the slide assembly at each station to control the plate fixtures at each station to alternately move to the loading / unloading station and the gluing station.

[0049] The controller is equipped with a control program that controls the movement of the board fixture. When the board fixture moves to the loading / unloading station at the first station, it loads and unloads the boards at that station. At the same time, the board fixture at the second station moves to the glue application station, where glue application is performed. Therefore, the ability to alternately move the board fixtures at different stations allows for continuous glue application even with a single operator, improving production efficiency.

[0050] In some embodiments, the loading station is equipped with an ultraviolet lamp, and a waste adhesive collection box is provided near the adhesive application station.

[0051] The ultraviolet lamp is used to irradiate the glued surface after application to determine the quality of the glue application. When the brush needle is not applying glue, it can move to the waste glue collection box to prevent waste glue from contaminating the board or machine.

[0052] The beneficial effects of this utility model's board gluing device are:

[0053] The panel gluing device of this utility model has at least two workstations and the operation procedures of the at least two workstations can be carried out alternately. When a single person controls the production line, while gluing is being done at some workstations, the gluing quality of the products at the other workstation that has completed gluing can be identified, thus avoiding production line stoppages and effectively improving production efficiency.

[0067] Example 1

[0068] In controller manufacturing, applying adhesive to the solder joints of the motor's four-board circuit board provides physical protection for the solder joints, preventing damage due to mechanical impact or wear. Currently, solder joint protection adhesives are applied using methods such as coating, spraying, selective coating, dispensing, and immersion. However, it is evident that current methods of applying adhesive to the solder joints of the motor's four-board circuit board still cannot effectively balance accuracy, efficiency, and cost.

[0069] In response, this embodiment discloses an adhesive application assembly, such as... Figure 1 As shown, including

[0070] The brush needle 1 is provided with bristles 103 arranged in a straight line, and the bristles 103 can brush the adhesive surface of the adhesive plate 2 to be brushed.

[0071] The bristles 103 of the brush needle 1 are arranged in a straight line, so that the entire brush surface has both a long side surface 101 and a narrow side surface 102, which makes it easy to control the area of ​​the brush needle 1 to apply glue.

[0072] Specifically, the brush needle 1 is a rectangular flat brush. Specifically, the motor 4 is rotated according to actual needs, controlled by a program.

[0073] The glue inlet channel 3 is connected to the brush needle 1 and supplies glue to the brush needle 1;

[0074] One end of the brush needle 1 is provided with brush bristles 103, and the other end is provided with a glue inlet. The glue inlet is used to connect with the glue inlet channel 3 to facilitate the supply of glue to the brush bristles 103.

[0075] A rotating mechanism, connected to the brush needle 1, is used to drive the brush needle 1 to rotate at a set angle on the adhesive surface.

[0076] The rotating mechanism, through its rotational motion, causes the brush needle 1 to rotate as well. When the brush needle 1 rotates 360°, it can apply glue to a large area of ​​the board surface. When it rotates 15°, it can apply glue to only the area within that 15° range, effectively balancing both large and small area glue application. Furthermore, by moving the rotating mechanism to move the brush needle 1, it can selectively apply glue to different locations, further improving the flexibility of the glue application process.

[0077] In this embodiment, the rotating mechanism includes a motor 4, a flange, and a shift fork 6.

[0078] One end of the flange is connected to the rotating shaft of the motor 4, and the other end of the flange is fixedly connected to the pull fork 6. The brush needle 1 is connected to the pull fork 6.

[0079] The flange is driven to rotate by the motor 4, preferably a servo motor 4, which in turn drives the fork 6 to rotate. That is, the brush needle 1 is driven to rotate by the rotating shaft of the motor 4.

[0080] Specifically, the servo motor 4 is fixed to the motor 4 mounting plate, the flange is locked onto the rotating shaft of the servo motor 4, and the shift fork is fixed to the flange. When the servo motor 4 rotates, the shift fork rotates accordingly, driving the dispensing valve 7 to rotate, and the brush needle 1 on the dispensing valve 7 rotates accordingly. That is, the rotation of the servo motor 4 drives the brush needle 1 to rotate, while the motor 4 mounting plate is fixed to a three-dimensional module that can move in three dimensions. This module allows the entire dispensing assembly to move.

[0081] In this embodiment, the brush needle 1 is connected to a dispensing valve 7 connected to the glue inlet channel 3. The dispensing valve 7 and the brush bristles 103 are located at both ends of the brush needle 1, and the brush needle 1 is connected to the fork 6 through the dispensing valve 7.

[0082] The dispensing valve 7 is used to control the glue feeding state of the glue inlet channel 3. The dispensing valve 7 is connected to the shift fork 6, making the entire structure more compact. In this embodiment, a bearing is also included, which is fixed to the mounting plate. The dispensing valve 7 is fitted with a rotating bushing 9, which is adapted to the inner ring of the bearing in the bearing housing 8. The dispensing valve 7 is positioned via the mounting plate.

[0083] A rotating bushing 9 is provided on the outer periphery of the dispensing valve 7. The rotating bushing 9 is adapted to the inner ring of the bearing in the bearing seat 8, so that the dispensing valve 7 can rotate more stably, thereby making the brush 103 needle rotate more stably.

[0084] Specifically, the dispensing valve 7 is equipped with an inlet connector 10, a first air pipe connector 11, and a second air pipe connector 12. Adhesive enters the dispensing valve 7 through the inlet connector 10. Compressed air is supplied through the first air pipe connector 11 and the second air pipe connector 12, controlling the opening and closing of the dispensing valve 7. When compressed air enters the first air pipe connector 11, the dispensing valve 7 closes, preventing adhesive from flowing out; when compressed air enters the second air pipe connector 12, the dispensing valve 7 opens, allowing adhesive to flow out. Whether compressed air enters the first air pipe connector 11 or the second air pipe connector 12 is determined by a program-controlled solenoid valve 13.

[0085] Specifically, the bearing is fixed to the mounting plate. The bearing housing 8 is placed inside the bearing, and the rotating bushing 9 is inserted into the inner ring of the bearing, allowing it to rotate. It is secured by a circlip 14 to prevent it from falling out.

[0086] The aforementioned brush 103 assembly uses a rectangular brush for applying adhesive. An added rotating mechanism allows for control of the brush's rotation. In confined spaces, the narrow side of the brush is used for application, while in other areas, the brush is rotated to apply adhesive using its wider side. This method is suitable for situations where the motor board area is small and some component locations cannot be glued, requiring avoidance of these conditions. Using a brush for adhesive application effectively overcomes the problem of thick adhesive coatings found in traditional methods.

[0087] Example 2

[0088] The adhesive application process on the solder joints of motor 4 boards in the controller branch factory is done manually. Workers use hand-held brushes and other tools to apply the adhesive to the solder joints, with a work efficiency of approximately 600 pieces / hour, which is low. Therefore,

[0089] This embodiment discloses a glue application device for a board 2, such as... Figure 3 , 5 As shown, it includes at least two workstations, each workstation including the glue application assembly of Example 1, and the operation processes of at least two workstations are carried out alternately.

[0090] The glue application assembly accurately and quickly applies glue to the board 2 at the workstation. At the same time, since the two workstations can move alternately, when a single person controls the production line, while some workstations are applying glue, the glue application quality of the products at the other workstation that has finished applying glue can be identified, avoiding production line stoppages and effectively improving production efficiency.

[0091] To achieve glue delivery to multiple workstations and to illustrate the movement between these workstations, for example, as follows: Figure 2 As shown, this embodiment includes a first station 15 and a second station 16. Compressed air enters the glue tank 17 through the compressed air inlet, forcing the glue in the glue tank 17 out through the glue outlet 18. The glue then enters the manifold block 20 through the hose 19. The glue then branches off from the manifold block 20 into two hoses 19, which connect to the dispensing valves 7 of the first station 15 and the second station 16.

[0092] In this embodiment, a clamp for positioning the plate 2 to be glued is provided below the glue application component. The glue application component is fixed on a multi-axis module. The multi-axis module drives the glue application component to move in multiple dimensions and apply glue to the plate 2 to be glued.

[0093] The function of the clamp for plate 2 is to position plate 2 so that the glue application assembly can apply glue to the plate 2 when it is stably placed. At the same time, since the glue application assembly is fixed on the multi-axis module, the glue application assembly can be driven to move in the X, Y and Z axis directions by the driving action of the multi-axis module, so that the brush 103 assembly can apply glue to each surface of plate 2.

[0094] Specifically, the three-axis module consists of an X-axis module, a translation connecting plate, a Y-axis module, a lifting connecting plate, and a Z-axis module.

[0095] In this embodiment, as Figure 7 As shown, the clamp for plate 2 includes a first support plate 210 and a second support plate 211.

[0096] The first support plate 210 and the second support plate are vertically arranged with their inner surfaces facing each other. The two ends of the glue-applied plate 2 are respectively fixedly mounted on the top of the first support plate 210 and the top of the second support plate 211.

[0097] The vertical arrangement of the first support plate 210 and the second support plate 211, with their surfaces facing each other, serves two purposes: firstly, it supports the plate 2 to be glued, facilitating the application of glue to the plate 2; secondly, the long side of the plate surface can better contact the plate 2, thereby improving the support effect of the plate 2; in addition, the support plate can prevent the glue from splashing out, thus protecting the entire system.

[0098] In this embodiment, a cylinder 212 is provided on the outer surface of the first support plate 210 and / or the outer surface of the second support plate 211.

[0099] The piston rod of the cylinder 212 points to the top of the support plate and is connected to a pressure block. The piston rod drives the pressure block to press against the end of the piece 2 to be coated with adhesive.

[0100] Since the cylinder 212 is located on the outer side of the support plate, the pressure block can be moved up and down by the extension and retraction of the piston rod of the cylinder 212. When the pressure block moves upward, that is, away from the glue plate 2 to be brushed, the glue plate to be brushed can be picked up. When the pressure block moves downward, the glue plate 2 to be brushed can be pressed down and fixed so that the glue plate 2 to be brushed can be brushed evenly.

[0101] In this embodiment, the top inner side of the first support plate 210 and / or the top inner side of the second support plate 211 have an L-shaped notch 23, and the end of the adhesive-brushed plate 2 is mounted on the L-shaped notch 23.

[0102] The L-shaped notch 23 can limit the end of the part 2 to be glued, preventing the part 2 to be glued from shifting.

[0103] In this embodiment, one end of the pressure block is connected to the piston rod, and the other end of the pressure block is bent downward at 90° and can press against the end of the adhesive plate 2 to be brushed on the L-shaped notch 23.

[0104] The pressure block presses down on the glue-applied board 2 through its bent end, which can more stably fix both ends of the board 2.

[0105] In this embodiment, the bottom surface of the pressing block is provided with a buffer pad 24, and the pressing block presses against the end of the adhesive board 2 to be brushed through the buffer pad 24.

[0106] The buffer pad 24 can prevent the sheet 2 to be coated with glue from being scratched.

[0107] In this embodiment, a wire baffle 25 is also included. The two ends of the wire baffle 25 are respectively fixed on the same side of the first support plate 210 and the second support plate 211. When applying glue, the lines of the board piece 2 to be glued are blocked by the wire baffle 25 on the outside directly below the board piece 2 to be glued.

[0108] Because adhesive may drip during the application of glue, and the board 2 to be glued is usually connected to a wire harness, if the adhesive drips onto the wire harness, it will affect the product quality. Therefore, the wire harness is placed outside the wire baffle 25. The wire baffle 25 can prevent the wire harness from falling under the board 2 to be glued and thus contaminating the wire harness with adhesive.

[0109] For example, the steps of the first support plate 210 and the second support plate 211 respectively support and position the left and right ends of the plate 2. The third support plate is used to support the middle position of the plate 2 to prevent the middle position of the plate 2 from collapsing during glue application, which could lead to abnormal glue application or damage to the plate 2. The wire baffle 25 is used to keep the wire harness of the plate 2 outside the hopper to prevent falling glue from contaminating the wire harness.

[0110] It also includes a plate 2 limiting plate, which is used to position the plate 2 in the front and back of the hopper. After placing the two plates 2 on the first support plate 210 and the second support plate 211, they are pushed to contact the plate 2 positioning plate to complete the placement action of the plate 2.

[0111] The first support plate 210 and the second support plate 211 each fix two cylinders 212. Each pair of cylinders 212 corresponds to one plate 2. The four cylinders 212 can press two plates 2 together. The pressure block is fixed to the cylinder 212, and the buffer pad is fixed to the pressure block. The cylinders 212 drive the buffer pad to press and release the plates 2. After the employee places two plates 2, they press the pressing button, and the buffer pad presses the two plates 2 together.

[0112] In this embodiment, as Figure 6 As shown, the plate 2 clamp is mounted on the slide assembly 26. One end of the slide assembly 26 is a loading and unloading station, and the other end of the slide assembly 26 is located below the glue application assembly and is also a glue application station.

[0113] The plate 2 clamp is set on the slide assembly 26 so that the plate 2 clamp can move along the length of the slide assembly 26, thereby avoiding the obstruction of the glue application assembly at the glue application station when inspecting the glue application quality.

[0114] After the employee starts the machine, the slide assembly 26 moves the plate 2 clamp to a fixed position inside the equipment to await glue application. During the glue application process, the slide assembly 26 stops moving. After the glue application is completed, the slide assembly 26 removes the plate 2 clamp from the equipment, stops moving, and waits for the employee to remove plate 2, place a new plate 2, and start the machine again.

[0115] In this embodiment, a controller is also included. The controller is connected to the slide assembly 26 on each station and controls the plate 2 clamps on each station to alternately move to the loading / unloading station and the glue application station.

[0116] The controller is equipped with a control program that controls the movement of the fixture for board part 2. When the fixture for board part 2 moves to the loading / unloading station on the first station 15, board part 2 is loaded / unloaded on the first station 15. At the same time, the fixture for board part 2 on the second station 16 moves to the glue application station, where glue application is performed. Therefore, the ability to alternately move the fixtures for board part 2 on different stations allows for continuous glue application even with a single operator, improving production efficiency.

[0117] In this embodiment, as Figure 4 As shown, the loading / unloading station is equipped with an ultraviolet lamp 27, and a waste adhesive receiving box is located near the adhesive application station. 28

[0118] The ultraviolet lamp 27 is used to irradiate the glued surface after application to determine the quality of the glue application. Specifically, the ultraviolet lamp is used to develop the color of the glue, making it easier to observe the glue application status. When the brush 103 needle is not applying glue, it can be moved to the waste glue collection box to prevent waste glue from contaminating the board 2 or the machine.

[0119] In addition, the device is also connected to an exhaust pipe that removes the glue odor from inside.

[0120] The multi-station design, with material loading, gluing, and unloading alternating between two stations, significantly improves production speed and meets the production line's cycle time. Simultaneously, a two-hand start-up method minimizes the risk of employee injuries from equipment impacts.

[0121] An automatic glue supply system is added. Compressed air forces the glue in glue tank 17 into dispensing valve 7. When dispensing valve 7 opens, the glue enters the brush.

[0122] Example 3

[0123] This embodiment also discloses that the adhesive application device for the board part 2 further includes a base assembly. Figures 1 to 8 As shown, the protective shield assembly.

[0124] The base assembly consists of a front hinged door, button box, right side plate of the base, base mounting plate, waste material receiving box, rear hinged door, left side plate of the base, electrical mounting plate, 13 sets of solenoid valves, pressure regulating valve, 17 glue tanks, frame, and feet.

[0125] In this embodiment, the front swing door, the rear swing door, the left side plate of the base, the right side plate of the base, and the base mounting plate are fixed to the outside of the frame.

[0126] In this embodiment, the electrical mounting plate is fixed inside the rack, dividing the rack interior into two parts. The rear space serves as an electrical cabinet, with the electrical mounting plate facing the rear hinged door. Opening the rear hinged door allows for the installation and maintenance of electrical components. The front space houses the glue container 17. Opening the front hinged door allows for the filling of glue into the glue container 17.

[0127] In this embodiment, the pressure regulating valve and the solenoid valve group 13 are fixed to the right side plate of the base. External compressed air is regulated by the pressure regulating valve and then introduced into the air inlet of the solenoid valve group 13. The solenoid valve group 13 controls the pressing and releasing of the cylinder 212 and the opening and closing of the dispensing valve 7, respectively.

[0128] In this embodiment, the waste collection box and the button box are fixed to the base mounting plate. The waste collection box is used to collect the waste glue discharged from the brush needle 1. The waste glue in the waste collection box is cleaned by employees regularly. There are two sets of button boxes, one set each at workstation 1 and workstation 2.

[0129] The protective cover assembly is mounted on the base mounting plate. It consists of the right side panel of the protective cover, the front swing door, the touch screen, the top panel of the protective cover, the exhaust pipe connection flange, the rear swing door, and the left side panel of the protective cover.

[0130] In this embodiment, the front swing door consists of an aluminum profile frame and a transparent acrylic panel. This allows observation of the adhesive application process.

[0131] In this embodiment, the touchscreen is embedded in the acrylic panel of the front swing door. Operations such as selecting the production model and adjusting the positioning can be performed on the touchscreen.

[0132] In this embodiment, the operation of the slide assembly 26 can be observed when the rear swing door is opened.

[0133] In this embodiment, the exhaust pipe is connected to a flange and then to the exhaust hose 19 inside the workshop to prevent the odor of the glue from overflowing into the equipment.

[0134] Example 4

[0135] This embodiment also discloses the specific usage methods of the above embodiments, such as... Figures 1 to 8 As shown, specifically:

[0136] Step 1: Place the two plates 2 into the plate 2 fixture at the first station 15, with the two plates 2 placed close together. One plate 2 is positioned left and right by the first support plate 210 and the second support plate 211, and its position is limited by the plate 2 limiting plate. The other plate 2 is positioned in the same way as the previous plate 2, and is placed at the rear end of the front plate 2 in the front-back direction.

[0137] Press the clamping button on the button box of the first station 15, and the cylinder 212 of the plate 2 clamp will drive the buffer pad to clamp the two plates 2 simultaneously. Press the start button on the button box of the first station 15, and the plate 2 clamp of the first station 15 will move to the glue application position to wait for glue application.

[0138] Step 2: After the fixture for part 2 moves to the glue application position, the three-axis module (first station 15) drives the glue application assembly to start moving. When the glue application assembly moves above part 2, the glue dispensing valve 7 opens and the glue application begins. Depending on the glue application position of part 2, the program automatically rotates the brush needle 1 to different angles. After the glue application is completed, the glue dispensing valve 7 closes, and at the same time, the three-axis module moves the glue application assembly above the waste glue receiving box to prevent the brush needle 1 from dripping residual glue.

[0139] Step 3: After the first station 15 completes the glue application, the fixture for panel 2 at the first station 15 moves to the loading / unloading station of the slide assembly 26 to await material removal. After the loading and clamping of panel 2 at the second station 16 is completed, the fixture for panel 2 at the second station 16 moves to the glue application position to await glue application. The panel 2 that has been glued at the first station 15 is then removed. After the material removal is completed, the complete loading, glue application, and unloading operation of the first station 15 is finished.

[0140] Step 4: After the fixture for part 2 moves to the glue application position, the three-axis module (second station 16) drives the glue application assembly to start moving. When the glue application assembly moves above part 2, the glue dispensing valve 7 opens and the glue application begins. Depending on the glue application position of part 2, the program automatically rotates the brush needle 1 to different angles. After the glue application is completed, the glue dispensing valve 7 closes, and at the same time, the three-axis module moves the glue application assembly above the waste glue receiving box to prevent the brush needle 1 from dripping residual glue.

[0141] Step 5: After the glue application at the second station 16 is completed, the fixture for panel 2 at the second station 16 moves to the loading position to await material removal. After the loading, clamping, and starting of the second station 16 are completed, the panel 2 with the glue applied at the second station 16 is removed. After the material removal is completed, the complete actions of loading, applying glue, and unloading at the second station 16 are finished.

[0142] After receiving the material, observe the glue application status of board 2. If it is normal, continue production; if abnormal, place the abnormal board 2 separately, stop feeding, find the cause, and resume production after resolving the problem.
