Description

Technical Field

[0001] This utility model relates to the technical field of glue application equipment for filter products, and in particular to an automatic glue application system for filter products without separators. Background Technology

[0002] Frameless air filters are widely used as main filters in cleanrooms, commercial spaces, and industrial ventilation and air conditioning systems. These products feature a large effective filtration area, low resistance, light weight, large dust holding capacity, and high air volume.

[0003] The traditional glue application process for this filter product involves manually handling the plateless filter to the glue application area, opening the glue application system, and manually applying the glue from left to right using the two-component sealant dispensing valve. After application, the product is carried to the designated workstation. However, this manual application method suffers from inconsistent glue volume control and uneven product movement. For large filters, two people are often required to handle them, and glue can easily spill out of the profile during transport, causing product contamination. Furthermore, manual glue application is physically demanding, and the quality is inconsistent due to variations in operator technique. This instability in glue volume can also cause the assembled filter to fail final product testing, resulting in complete product scrap and reduced overall production quality. Utility Model Content

[0004] In order to improve the glue application efficiency and product quality of diaphragmless filter products, this utility model provides an automatic glue application system for diaphragmless filter products.

[0005] The automatic glue application system for the diaphragmless filter product provided in this application adopts the following technical solution:

[0006] An automatic glue application system for a diaphragmless filter product includes a loading and unloading assembly, a transfer robot, a glue application mechanism, and a control assembly. The glue application mechanism includes a glue feeder, a glue application table, and a glue application component. The glue feeder supplies glue to the glue application component. The glue application component is located on the glue application table and is used to apply glue to the filter product. The transfer robot is located between the loading and unloading assembly and the glue application table and is used to place or move the filter product from the glue application table. The control assembly provides integrated power supply and control for the transfer robot and the glue application mechanism.

[0007] By adopting the above technical solution, the transfer robot transfers the un-glued filter products located on the loading and unloading components to the gluing table. The glue supply machine supplies glue to the gluing components, which then apply glue to the filter products. After gluing is completed, the transfer robot transfers the glued filter products back to the loading and unloading components. The fully mechanized operation achieves a standardized process for gluing, reduces labor costs, and improves the gluing efficiency and product quality of the filter products.

[0008] Optionally, the glue application assembly includes:

[0009] A base, which is placed on a glue application table and used to place the filter product, and a fixing component for fixing the filter product is provided on the base;

[0010] A rotating component, which is mounted on a base and is used to drive the filter product to rotate along its bottom edge;

[0011] A glue gun is movably mounted on a glue dispensing table, extending toward the glue application area of ​​the filter product. The glue dispensing table is equipped with a moving component that drives the glue gun to move.

[0012] By adopting the above technical solution, the transfer robot places the filter product on the base, the fixing component secures the filter product, and the rotating component starts to rotate the filter product, causing the filter product to tilt as a whole to leave space for the glue gun nozzle to move and apply glue. The moving component moves the glue gun until the glue gun nozzle moves to the starting position of the glue application area. After the glue application is completed, the moving component moves the glue gun away from the filter product, the rotating component moves the filter product back to the correct position, the fixing component opens, and the transfer robot removes the glued filter product from the base. This realizes a mechanized glue application process for filter products, eliminating the need for manual handling and glue application, reducing labor costs, and improving the glue application efficiency and product quality of filter products.

[0013] Optionally, the fixing component includes:

[0014] A cradle frame, wherein the cradle frame is mounted on a base, and the rotating component is connected to the cradle frame and is used to drive the cradle frame to rotate;

[0015] A fixed clamping plate, which is fixed on the cradle frame and extends horizontally;

[0016] A movable clamping plate is slidably mounted on the cradle frame and extends horizontally. A fixed clamping plate is arranged parallel to the movable clamping plate, and a limiting space is formed between the fixed clamping plate and the movable clamping plate to limit the position of the filter product.

[0017] A detection sensor is mounted on the cradle frame and is used to detect whether the filter product is in place. The signal output terminal of the detection sensor is electrically connected to the control component. The cradle frame is equipped with a clamping cylinder that drives the moving clamping plate to slide toward the fixed clamping plate. The signal input terminal of the clamping cylinder is electrically connected to the control component.

[0018] By adopting the above technical solution, the detection sensor detects that the filter product has fallen into the limiting space and transmits the signal to the control component. The control component controls the clamping cylinder to start, so that the moving clamping plate moves toward the fixed clamping plate. The moving clamping plate and the fixed clamping plate cooperate to clamp the filter product, thereby fixing the filter product. After the glue is applied, the clamping cylinder drives the moving clamping plate to move back to the initial position, thereby improving the stability of the filter product during the glue application process and thus improving the glue application quality of the filter product.

[0019] Optionally, the rotating member includes:

[0020] A rotating ring, which is fixed to one of the outer side walls of the cradle frame;

[0021] A motor is mounted on a base and its output end is connected to a rotating ring. The base is equipped with a slotted in-situ photoelectric sensor, and the rotating ring is equipped with a shielding plate. In the initial state, the shielding plate extends into the slot of the in-situ photoelectric sensor. The signal output end of the in-situ photoelectric sensor is electrically connected to the control component, and the signal input end of the motor is electrically connected to the control component.

[0022] By adopting the above technical solution, in the initial state, the shielding plate extends into the slot of the in-situ photoelectric sensor. After the filter product is successfully positioned and fixed, the motor starts to drive the rotating ring to rotate. The rotating ring drives the filter product to rotate and tilt through the cradle frame. After the glue is applied, the motor drives the rotating ring to move back until the shielding plate moves back into the slot of the in-situ photoelectric sensor. At this time, it means that the cradle frame has returned to the correct position. The in-situ photoelectric sensor transmits a signal to the control component, and the control component controls the motor to stop rotating, thereby realizing the rotation and reset of the cradle frame and improving the convenience of applying glue to the filter product.

[0023] Optionally, the moving component includes:

[0024] X-axis electric slide, the X-axis electric slide is fixed on the glue application table and extends along the X-axis direction;

[0025] The Y-axis electric slide is mounted on the X-axis electric slide and extends along the Y-axis direction.

[0026] The Z-axis cylinder is mounted on the slider of the Y-axis slide table. The driving direction of the Z-axis cylinder extends along the length of the glue gun, and the glue gun is fixed on the moving end of the Z-axis cylinder.

[0027] By adopting the above technical solution, the X-axis electric slide table drives the Y-axis electric slide table, the Z-axis cylinder, and the glue gun to move along the X-axis direction on the glue application table. The Y-axis electric slide table drives the Z-axis cylinder and the glue gun to move along the Y-axis direction on the X-axis electric slide table. The Z-axis cylinder drives the glue gun to move in the direction of approaching or moving away from the filter product, thereby realizing the moving glue application of the glue gun and improving the convenience of glue application for the filter product.

[0028] Optionally, there are two glue application stations and two glue application components, each corresponding to one of the glue application stations.

[0029] By adopting the above technical solution, two glue application stations can simultaneously apply glue to two filter products, thereby improving the efficiency of glue application for filter products.

[0030] Optionally, the loading and unloading assembly includes a loading trolley and a unloading trolley. The loading trolley is used to load filter products without adhesive, and the unloading trolley is used to load filter products with adhesive. A limiting assembly is provided on the ground to limit the movement of the loading trolley and the unloading trolley.

[0031] By adopting the above technical solution, the transfer robot transfers the filter products on the loading trolley to the glue application station for glue application. After glue application, the filter products are transferred to the unloading trolley. The positions of the loading trolley and the unloading trolley are limited by the limiting components, which facilitates the operation of the transfer robot and improves the glue application efficiency of the filter products.

[0032] Optionally, the limiting assembly includes a left guide limiting plate, a right guide limiting plate, and a front limiting plate, all of which are fixed to the ground and located on the left, right, and front sides of the loading trolley, respectively.

[0033] By adopting the above technical solution, the left guide limit plate, the right guide limit plate and the front limit plate work together to limit the loading trolley and the unloading trolley, so as to keep the loading and unloading trolleys in a fixed position during operation, which makes it easier for the transfer robot to pick up the filter products.

[0034] Optionally, the transfer robot is a six-axis robotic arm robot, and the front end of the transfer robot has a gripper assembly for holding the filter product.

[0035] Optionally, the gripper assembly includes a left gripper and a right gripper. The front end of the transfer robot has a linear guide frame. The left gripper and the right gripper slide on the linear guide frame via corresponding linear drive components. The linear guide frame is equipped with an in-situ detection sensor, a left visual positioning camera, and a right visual positioning camera. The in-situ detection sensor is used to detect whether there is a filter product in front of the linear guide frame. The left visual positioning camera and the right visual positioning camera are used to detect the left and right side positions of the filter product, respectively. The signal output terminals of the in-situ detection sensor, the left visual positioning camera, and the right visual positioning camera are electrically connected to the signal input terminals of the control component. The signal input terminal of the linear drive component is electrically connected to the signal output terminal of the control component.

[0036] By adopting the above technical solution, the in-situ detection sensor detects the presence of filter products in front of the linear guide frame. The left and right vision cameras automatically scan the edges to find the left and right limit positions of the filter products. Finally, the linear drive unit drives the left and right grippers to move to the limit positions of the products to perform the gripping operation. At the same time, the left and right grippers cooperate with the linear guide frame to improve the stability of the filter products during the transfer process.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. The transfer robot transfers the un-glued filter products located on the loading and unloading components to the gluing table. The glue supply machine supplies glue to the gluing components, which then apply glue to the filter products. After gluing is completed, the transfer robot transfers the glued filter products back to the loading and unloading components. This fully mechanized operation standardizes the gluing process, reduces labor costs, and improves the gluing efficiency and product quality of the filter products.

[0039] 2. No manual handling of filter products is required. Mechanical glue application eliminates quality differences caused by experience, skills, and techniques in manual glue application, thereby improving the consistency of product quality.

[0040] 3. By using a dual-station glue application station, the glue application time for filter products can be shortened, thereby improving the glue application efficiency of filter products. Attached Figure Description

The glue application mechanism 3 includes a glue feeder 31, a glue application table 32, and a glue application component 33. The glue feeder 31 is used to supply glue to the glue application component 33, and the glue application component 33 is located on the glue application table 32 and is used to apply glue to the filter product 34.

[0056] Reference Figure 1 and Figure 2 The loading and unloading assembly 1 includes a loading trolley 11 and an unloading trolley 12. The loading trolley 11 is used to load the filter product 34 without glue, and the unloading trolley 12 is used to load the filter product 34 after glue application. The structure of the loading trolley 11 and the unloading trolley 12 is consistent with the structure of the handcart in the prior art, and will not be described in detail in this application.

[0057] Reference Figure 1 and Figure 3 The ground is provided with limiting components 5 for limiting the loading trolley 11 and unloading trolley 12. The limiting components 5 are used to keep the loading trolley 11 and unloading trolley 12 in a fixed position during operation. There are two limiting components 5, which correspond to the loading trolley 11 and the unloading trolley 12 respectively. The following description takes the limiting component 5 corresponding to the loading trolley 11 as an example.

[0058] Reference Figure 1 , Figure 2 and Figure 3 The limiting component 5 includes a left guide limiting plate 51, a right guide limiting plate 52, and a front limiting plate 53. The left guide limiting plate 51, the right guide limiting plate 52, and the front limiting plate 53 are all fixed on the ground and are located on the left, right, and front sides of the loading trolley 11, respectively. The left guide limiting plate 51, the right guide limiting plate 52, and the front limiting plate 53 form a U-shaped cavity that limits the loading trolley 11. The outer side walls of the left guide limiting plate 51 and the right guide limiting plate 52 opposite to the front limiting plate 53 each have an outwardly extending first guide plate 54, and the upper surfaces of the left guide limiting plate 51 and the right guide limiting plate 52 each have an upwardly and outwardly extending second guide plate 55.

[0059] Reference Figure 1 and Figure 4 The transfer robot 2 is located between the loading / unloading assembly 1 and the glue application table 32 and is used to place or remove the filter product 34 from the glue application table 32. The transfer robot 2 is any six-axis robotic arm robot in the prior art. The structure and working principle of the six-axis robotic arm robot are consistent with those in the prior art (refer to model ZAZC-180XD-B), and will not be described in detail here.

[0060] Reference Figure 1 , Figure 4 and Figure 5The front end of the transfer robot 2 has a gripper assembly 21 for gripping the filter product 34. The gripper assembly 21 includes a left gripper 211 and a right gripper 212. The front end of the transfer robot 2 has a linear guide frame 22. The left gripper 211 and the right gripper 212 slide on the linear guide frame 22 through corresponding linear drive members 23. The linear guide frame 22 has two sets of slide bars 221 along the length direction, which are respectively corresponding to the left gripper 211 and the right gripper 212. Taking the left gripper 211 as an example, the left gripper 211 has a moving block 24 on the side wall facing the linear guide frame 22. The moving block 24 is sleeved on the slide bar 221. The driving end of the linear drive member 23 is connected to the left gripper 211 and is used to drive the left gripper 211 to move along the length direction of the slide bar 221. The signal input end of the linear drive member 23 is electrically connected to the signal output end of the control component 4.

[0061] Reference Figure 4 , Figure 5 and Figure 6 In this embodiment, the linear drive component 23 is an electric actuator. The telescopic end of the electric actuator is connected to the left gripper 211. The inner sidewalls of the left gripper 211 and the right gripper 212 are provided with rubber pads for the wear-reducing filter product 34. In other feasible embodiments, the linear drive component 23 can be replaced by any device or structure with linear drive capability, such as a hydraulic cylinder, a pneumatic cylinder, or a motor lead screw.

[0062] Reference Figure 4 , Figure 5 and Figure 6 The guide rail 22 is equipped with an in-situ detection sensor 25, a left visual positioning camera 26, and a right visual positioning camera 27. The in-situ detection sensor 25 is an infrared sensor (refer to model E18-D80NK) used in the prior art to detect whether there is a filter product 34 in front of the guide rail 22. When there is a filter product 34 in front of the guide rail 22, the filter product 34 blocks the light emitted by the in-situ detection sensor 25. The in-situ detection sensor 25 transmits this signal to the control component 4. The left visual positioning camera 26 and the right visual positioning camera 27 are used to detect the left and right sides of the filter product 34, respectively. Both the left visual positioning camera 26 and the right visual positioning camera 27 are vision cameras with edge-finding function (refer to model ZEBRA VS70 for structure and principle). The signal output terminals of the in-situ detection sensor 25, the left visual positioning camera 26, and the right visual positioning camera 27 are electrically connected to the signal input terminal of the control component 4.

[0063] Reference Figure 1 , Figure 5 and Figure 6The in-situ detection sensor 25 detects the presence of the filter product 34 in front of the linear guide frame 22. The left visual positioning camera 26 and the right visual positioning camera 27 automatically patrol the edge to find the left and right extreme positions of the filter product 34. Finally, the linear drive component 23 drives the left gripper 211 and the right gripper 212 to move to the extreme positions of the product to perform the gripping operation. At the same time, the left gripper 211 and the right gripper 212 cooperate with the linear guide frame 22 to improve the stability of the filter product 34 during the transfer process.

[0064] Reference Figure 1 and Figure 7 There are two glue dispensing tables 32, and the two glue dispensing tables 32 have the same structure. There are two glue dispensing components 33, which correspond one-to-one with the glue dispensing tables 32. The glue supply machine 31 is connected to the two glue dispensing components 33 and is used to supply glue to the two glue dispensing components 33. The following description only takes one glue dispensing component 33 as an example. The glue dispensing component 33 includes a base 35, a rotating part 36 and a glue gun 37.

[0065] Reference Figure 1 , Figure 7 and Figure 8 The base 35 is fixed on the glue application table 32 and extends along the length of the glue application table 32. The base 35 is U-shaped with the open end facing upward and is used to place the filter product 34. The base 35 is provided with a fixing component 6 for fixing the filter product 34.

[0066] Reference Figure 1 , Figure 7 and Figure 8 The fixing assembly 6 includes a cradle frame 61, a fixed clamping plate 62, a movable clamping plate 63, and a detection sensor 64. The cradle frame 61 is disposed on the inner wall of the base 35 and is parallel to the base 35. The fixed clamping plate 62 is fixed on the cradle frame 61 and extends horizontally, with its length direction aligned with that of the cradle frame 61. The movable clamping plate 63 is slidably disposed on the cradle frame 61 and extends horizontally, with its length parallel to that of the fixed clamping plate 62. The sliding direction of the movable clamping plate 63 is towards or away from the fixed clamping plate 62. There is a limiting space 65 between plate 62 and moving clamping plate 63 to limit the filter product 34. The width of the limiting space 65 is greater than the width of the filter product 34. The cradle frame 61 is provided with a clamping cylinder 66 that drives the moving clamping plate 63 to slide toward the fixed clamping plate 62. The signal input terminal of the clamping cylinder 66 is electrically connected to the control component 4. The movement process of the clamping cylinder 66 is set to the width of the limiting space 65 minus the width of the filter product 34 to adapt to the clamping of filter products 34 of different specifications.

[0067] Reference Figure 1 , Figure 7 and Figure 8The detection sensor 64 is located on one side wall of the cradle frame 61. The detection sensor 64 adopts any photoelectric sensor or infrared sensor in the prior art. It is mainly used to detect whether the filter product 34 is placed in the limiting space 65. The signal output terminal of the detection sensor 64 is electrically connected to the control component 4. When there is no filter product 34 on the cradle frame 61, there is no obstruction in front of the detection sensor 64. When the filter product 34 is placed on the cradle frame 61, the filter product 34 obstructs the front of the detection sensor 64. The detection sensor 64 detects the change in signal and transmits this signal to the control component 4. The control component 4 controls the movement of the movable clamp 63.

[0068] Reference Figure 7 , Figure 8 and Figure 9 A rotating component 36 is mounted on the base 35 and connected to the cradle frame 61, and is used to drive the filter product 34 to rotate along its bottom edge. The rotating component 36 includes a rotating ring 361 and a motor 362. The rotating ring 361 is fixed to one of the outer side walls of the cradle frame 61 and is located between the base 35 and the cradle frame 61. The bottom end of the rotating ring 361 has teeth (not shown in the figure). The motor 362 is fixed to the side wall of the base 35. The output end of the motor 362 has a drive tooth 363. The motor 362 is driven by the drive tooth 363 meshing with the teeth at the bottom of the rotating ring 361. The top of the outer side wall of the base 35... A slotted in-situ photoelectric sensor 351 is fixedly provided. The in-situ photoelectric sensor 351 adopts the slotted photoelectric sensor in the prior art (the structure and principle can be referred to model ITR-GK105). The slot of the in-situ photoelectric sensor 351 faces the cradle frame 61. A shielding plate 364 is fixedly provided at the top of the rotating ring 361. In the initial state, the filter product 34 is in a vertical state, and the shielding plate 364 extends into the slot of the in-situ photoelectric sensor 351. The signal output terminal of the in-situ photoelectric sensor 351 is electrically connected to the control component 4, and the signal input terminal of the motor 362 is electrically connected to the control component 4.

[0069] Reference Figure 7 , Figure 8 and Figure 9 In the initial state, the shielding plate 364 extends into the slot of the in-situ photoelectric sensor 351. After the filter product 34 is successfully positioned and fixed, the motor 362 starts and drives the rotating ring 361 to rotate. The rotating ring 361 drives the filter product 34 to rotate and tilt through the cradle frame 61. After the glue is applied, the motor 362 drives the rotating ring 361 to move back until the shielding plate 364 moves back into the slot of the in-situ photoelectric sensor 351. At this time, it means that the cradle frame 61 has returned to the correct position. The in-situ photoelectric sensor 351 transmits a signal to the control component 4. The control component 4 controls the motor 362 to stop rotating, thereby realizing the rotation and reset of the cradle frame 61 and improving the convenience of applying glue to the filter product 34.

[0070] Reference Figure 1 , Figure 7 and Figure 10 The glue gun 37 is movably mounted on the glue dispensing table 32. The glue inlet of the glue gun 37 is connected to the glue dispensing machine 31 through the glue supply pipe (not shown in the figure). The structure and working principle of the glue dispensing machine 31 are consistent with the prior art. The glue dispensing machine 31 periodically draws glue from the upstream glue supply chamber into the storage tank, heats the glue in the storage tank and keeps it at a constant temperature, and maintains the glue supply to the glue dispensing table 32. The glue gun 37 extends at an angle toward the glue application area of ​​the filter product 34. The glue dispensing table 32 is equipped with a moving component 7 that drives the glue gun 37 to move.

[0071] Reference Figure 1 , Figure 7 and Figure 10 The moving component 7 is powered by a cable chain. The moving component 7 includes an X-axis electric slide 71, a Y-axis electric slide 72 and a Z-axis cylinder 73. The structural principles of the X-axis electric slide 71 and the Y-axis electric slide 72 can refer to the rodless electric cylinder in the prior art (refer to the AS120 lead screw slide). The Z-axis cylinder 73 adopts the rodless cylinder in the prior art (refer to the CY1 RG50).

[0072] Reference Figure 1 , Figure 7 and Figure 10 An X-axis electric slide 71 is fixed on the glue dispensing table 32 and extends along the X-axis direction. The extension direction of the X-axis electric slide 71 is parallel to the extension direction of the fixed clamping plate 62. A Y-axis electric slide 72 is mounted on the X-axis electric slide 71 and extends along the Y-axis direction. The Y-axis electric slide 72 is fixed on the slider of the X-axis electric slide 71, and the extension direction of the Y-axis electric slide is perpendicular to the extension direction of the fixed clamping plate 62. An upwardly extending support block 74 is fixed on the slider of the Y-axis electric slide 72. A Z-axis cylinder 73 is fixed on the top of the support block 74, and the driving direction of the Z-axis cylinder 73 extends along the length of the glue gun 37. The glue gun 37 is fixed on the moving end of the Z-axis cylinder 73.

[0073] Reference Figure 1 , Figure 7 and Figure 10After the filter product 34 is tilted, the X-axis electric slide 71 drives the Y-axis electric slide 72, the Z-axis cylinder 73, and the glue gun 37 to move along the X-axis direction on the glue application table 32. The Y-axis electric slide 72 drives the Z-axis cylinder 73 and the glue gun 37 to move along the Y-axis direction on the X-axis electric slide 71. The glue application start point and the return point stroke are preset according to the size of the filter product 34. The Z-axis cylinder 73 drives the glue gun 37 to move along the direction close to the filter product 34. With the space margin left by the overall tilt of the filter product 34, the glue gun 37 can move to apply glue. When the glue gun 37 moves to the preset return point, it pauses for 0.1-0.5 seconds (depending on the production process). Glue application continues until it returns to the glue application point, then glue application stops, the glue gun 37 moves back, and the cradle frame 61 returns to the center. This improves the convenience of applying glue to the filter product 34.

[0074] Reference Figure 1 The control component 4 is used to provide integrated power supply and control for the transfer robot 2 and the glue dispensing mechanism 3. The control component 4 includes a central control console 41 and an integrated electrical control box 42. The central control console 41 is equipped with an HMI, which is used to connect to the program controller, configure operating parameters, view the operating status, and provide prompts to personnel through audible and visual alarms. The integrated electrical control box 42 is used to provide unified power supply for the equipment that requires power in the glue dispensing system. In this embodiment, the program control of the transfer robot 2, the visual positioning camera, each motor, and the cylinder, as well as the setting of the initial position, are conventional contents in the prior art and will not be described in detail in this application.

[0075] The workflow of Embodiment 1 of this application is as follows: The loading trolley 11 and unloading trolley 12 are pushed to a fixed position, and the transfer robot 2 grabs and places the un-glued filter product 34 onto the cradle frame 61 on one of the gluing tables 32. Then, the clamping cylinder 66 is activated, causing the moving clamping plate 63 to move. The moving clamping plate 63 and the fixed clamping plate 62 cooperate to clamp and position the filter product 34. Then, the motor 362 drives the filter product 34 to rotate 15-30° along the bottom edge (depending on the process) through the rotating ring 361 and the cradle frame 61. At this time, the transfer robot 2 moves forward. The robot 2 clamps the un-glued filter product 34 and transfers it to another gluing table 32. Then, the glue gun 37 moves to the preset position, and the Z-axis cylinder 73 pushes the glue gun 37 so that the glue head moves to the gluing start point on the filter product 34. The X-axis electric slide table 71 drives the glue gun 37 to reciprocate to apply glue. After the gluing is completed, the glue gun 37 moves back, the cradle frame 61 returns to the center, the clamping cylinder 66 moves back, and the transfer robot 2 places the glued filter product 34 onto the unloading trolley 12. The process of continuous gluing of the filter product 34 is repeated.

[0076] The automatic glue application system provided in Example 1 was applied to the glue application process of a 4*4*110mm non-segmented filter product for mechanical glue application, while a traditional manual glue application was performed simultaneously. The two glue application methods were compared, and the comparison results are shown in Table 1. The glue application defect rate was based on industry testing standards.

[0079] As shown in Table 1, the automatic glue application system provided in this application eliminates the quality differences caused by experience, skills, and techniques in manual glue application through mechanical glue application. This increases the production speed of products, reduces labor costs, and improves the stability of glue application quality. At the same time, it realizes the standardization of the glue application process, controls the amount of glue used, and improves the convenience of management.
