Description

Technical Field

[0001] This invention relates to the field of adhesive application equipment technology, and in particular to an adhesive application amount weighing and monitoring device with an anti-interference structure. Background Technology

[0002] In coating processes for strip-shaped substrates such as paper and film, spraying or roller coating are commonly used. Precise control of the adhesive application rate is crucial for product quality and production costs, directly impacting the product's bonding strength, surface smoothness, and the stability of subsequent lamination processes. Traditional methods for detecting adhesive application rate rely on manual sampling or offline laboratory analysis. These methods suffer from significant time lag; during high-speed production line operation, real-time adhesive application data is unavailable, failing to meet the quality control requirements of continuous production. Furthermore, after adhesive application, the base paper needs to be laminated with other substrates and undergo a drying process. If the adhesive application rate is below the standard range, insufficient adhesion between the laminated layers will lead to delamination and separation defects. Conversely, if the adhesive application rate exceeds the standard, it will increase the load on the drying process, preventing the adhesive layer from drying sufficiently, resulting in lamination blistering, bonding failure, and other problems, severely impacting product yield.

[0003] The aforementioned existing technologies have several shortcomings: First, the detection timeliness is poor, manual or offline detection cannot keep pace with the high-speed production rhythm, and feedback on sizing abnormalities is delayed, increasing the output of defective products; second, the stability of weighing data is insufficient, and there is a lack of targeted mechanical anti-interference structures; third, quality traceability is lacking, and no mechanism has been established to correspond sizing amount data with specific paper areas, making it impossible to quickly locate the sizing area corresponding to the problem. Summary of the Invention

[0004] To address the technical deficiencies in the background art, this invention proposes a glue application amount weighing and monitoring device with an anti-interference structure. To further solve the aforementioned technical problems and meet practical needs, the specific technical solution is as follows: A glue application amount weighing and monitoring device with an anti-interference structure includes a weighing and detection component and a glue bucket placed above the weighing and detection component. The weighing and detection component is connected to a glue spraying component. The weighing and detection component includes a base, an outer tray placed above the base for placing the glue bucket, a weighing sensor disposed inside the base, and an inner tray disposed between the base and the outer tray. A pressure column is disposed at the center of the lower surface of the inner tray, and the lower end of the pressure column is connected to the weighing sensor. A plurality of first buffers are disposed between the outer tray and the inner tray. The first buffers are symmetrically disposed on the upper surface of the inner tray and connected to the outer tray. A second buffer connected to the pressure column is disposed on the top of the base. Lifting supports are symmetrically disposed on the lower surface of the base. The glue spraying component includes a frame, a plurality of glue spray nozzles mounted on the frame, and a marking component disposed downstream of the glue spray nozzles. The glue spraying component is equipped with a delivery pump, which is connected to the material pipe from the glue bucket and the glue spray nozzles through delivery pipes.

[0005] As a further technical solution of the present invention, the first buffer includes an outer sleeve that passes through the inner tray, a sliding post disposed inside the outer sleeve and whose upper end is connected to the lower surface of the outer tray, and a bottom cover disposed at the lower end of the outer sleeve. A first spring is sleeved on the outside of the outer sleeve, and the two ends of the first spring abut against the outer tray and the inner tray respectively. A first sealing ring is provided between the sliding post and the outer sleeve and sleeved on the outside of the sliding post.

[0006] As a further technical solution of the present invention, a boss that mates with the lower end of the outer sleeve is provided at the center of the upper surface of the bottom cover. The boss is placed inside the lower end of the outer sleeve, and a one-way air valve that can vent air into the inner part of the outer sleeve is provided inside the boss. A second sealing ring that is sleeved on the outside of the one-way air valve is provided between the one-way air valve and the boss. An air hole communicating with the one-way air valve is provided through the bottom of the bottom cover. A sealing ring is installed on the upper surface of the bottom cover, and a sealing groove that mates with the sealing ring is provided on the lower end surface of the outer sleeve.

[0007] As a further technical solution of the present invention, guide rods are symmetrically arranged on both sides of the outer sleeve, the lower end of the guide rod passes through the inner tray and is connected to the bottom cover, the upper end of the guide rod is provided with a top plate, and a second spring sleeved on the outside of the guide rod is provided between the inner tray and the top plate.

[0008] As a further technical solution of the present invention, the lifting support includes a support cylinder, an installation cylinder disposed at the upper end of the support cylinder, and a first lead screw disposed in the support cylinder and the installation cylinder. The upper end of the first lead screw is connected to the base, and the lower end of the first lead screw is placed inside the support cylinder. Guide grooves are symmetrically arranged on the inner wall of the support cylinder. A guide block that can slide in the guide groove is provided at the lower end of the first lead screw. A first threaded sleeve is disposed inside the installation cylinder. The first threaded sleeve is sleeved on the first lead screw. A pad is disposed below the first threaded sleeve. Rotary rods are symmetrically connected to the top of the first threaded sleeve.

[0009] As a further technical solution of the present invention, the second buffer includes a fixed cylinder disposed outside the pressure column and connected at its lower end to the upper surface of the base, and hook springs symmetrically disposed between the fixed cylinder and the pressure column and inclined downward. The two ends of the hook springs are hooked to mounting seats, and the two ends of the hook springs are respectively connected to the fixed cylinder and the pressure column through the mounting seats.

[0010] As a further technical solution of the present invention, the glue spraying assembly further includes a roller arranged along the material feeding direction and rotatably connected to the frame, a support rod connected to the frame at both ends, and a fixed seat fixedly sleeved on the outside of the support rod. The glue spraying nozzles are installed on the lower surface of the fixed seat and are evenly spaced along the length direction of the fixed seat, and the glue spraying nozzles are oriented downwards.

A marking spray gun is provided on the upper surface of the second threaded sleeve, and the marking spray gun is oriented upwards.

[0012] The beneficial effects of this invention are as follows: the first and second buffer components in the weighing detection assembly effectively ensure that the weight of the glue bucket is stably applied to the weighing sensor, maintaining stable pressure changes even as the mass of the glue bucket gradually decreases, reducing fluctuations in weighing data and improving measurement accuracy. Simultaneously, the lifting support allows for flexible adjustment of the weighing assembly's height to adapt to different production environments, further enhancing the device's applicability. Regarding glue application monitoring, the system records the paper feed length in real time via an encoder and periodically calculates the average glue application amount for each area, ensuring uniform and consistent glue application. When the marking component detects an abnormal glue application amount, it promptly prints a color mark on the corresponding area's edge of the base paper, facilitating rapid tracing and handling of problematic areas, thereby significantly improving production quality and efficiency.

Detailed Implementation

[0021] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0022] like Figures 1 to 7 As shown, the present invention provides a technical solution: a glue application amount weighing and monitoring device with an anti-interference structure, including a weighing and detection component 2 and a glue bucket 1 placed above the weighing and detection component 2. The weighing and detection component 2 is connected to a glue spraying component 6. The weighing and detection component 2 includes a base 23, an outer tray 21 disposed above the base for placing the glue bucket 1, a weighing sensor 24 disposed inside the base 23, and an inner tray 22 disposed between the base 23 and the outer tray 21. A pressure column 221 is disposed at the center of the lower surface of the inner tray 22, and the lower end of the pressure column 221 is connected to the weighing sensor. A plurality of first buffer members 3 are provided between the outer tray 21 and the inner tray 22. The first buffer members 3 are symmetrically arranged on the upper surface of the inner tray 22 and connected to the outer tray 21. A second buffer member 5 connected to the pressure column 221 is provided on the top of the base 23. Lifting supports 4 are symmetrically arranged on the lower surface of the base 23. The glue spraying assembly 6 includes a frame 60, a plurality of glue spraying nozzles 64 installed on the frame 60, and a marking assembly 65 located downstream of the glue spraying nozzles 64. The glue spraying assembly 6 is provided with a delivery pump 61. The delivery pump 61 is connected to the discharge pipe of the glue tank 1 and the glue spraying nozzles 64 through a delivery pipe.

[0023] In this invention, the glue bucket 1 is placed on the outer tray 21 of the weighing and detection assembly 2. The delivery pump 61 of the glue spraying assembly 6 connects the glue bucket 1 and the glue spray nozzle 64 via a delivery pipe, which can stably deliver the glue liquid in the glue bucket 1 to the glue spray nozzle 64, providing a basic guarantee for subsequent glue application. In the weighing and detection assembly 2, the inner tray 22 transfers the weight of the glue bucket 1 to the weighing sensor 24 inside the base 23 through the pressure column 221. The first buffer 3 between the outer tray 21 and the inner tray 22, and the second buffer 5 between the base 23 and the pressure column 221, constitute a mechanical anti-interference structure, which allows the mass of the glue bucket 1 to be stably applied to the weighing sensor 24. Even if the weight of the glue bucket 1 gradually decreases due to glue application, its pressure on the weighing sensor 24 can be steadily reduced.

[0024] Specifically, in the first buffer 3, when the sliding column 31 squeezes the air inside the outer sleeve 32, the bottom cover 33 will separate from the bottom of the outer sleeve 32, and the air will be discharged in conjunction with the first spring 321 to achieve stable pressure transmission. When the weight of the rubber bucket 1 decreases, the first spring 321 gradually returns to its original state, the sliding column 31 rises, and the external air slowly enters the outer sleeve 32 through the air hole 333 and the one-way air valve 332 to ensure that the pressure decreases steadily. The hook spring 53 of the second buffer 5 further assists in the stable transmission of pressure and effectively improves the stability of the weighing data.

[0025] The lifting supports 4 symmetrically arranged on the lower surface of the base 23 ensure that the weighing and detection assembly 2 remains horizontal. Rotating the rotating rod 442 can drive the first threaded sleeve 44 to rotate. Under the limiting action of the guide block 431 and the guide groove 411, the first lead screw 43 will rise or fall accordingly, thereby adjusting the height of the base 23 and preventing the weighing and detection assembly 2 from tilting and affecting the weighing accuracy. At the same time, the marking assembly 65 of the glue spraying assembly 6 is installed downstream of the glue spraying nozzle 64. The glue spraying nozzle 64 is mounted on the support rod 62 through the fixed seat 63, which can evenly apply glue to the packaging paper conveyed by the roller 601. In the marking assembly 65, the motor 651 drives the second lead screw 652 to rotate, which allows the second threaded sleeve 653 to drive the marking spray gun 654 to move. After calculating the amount of glue applied by combining the weight data collected by the weighing sensor 24, a color mark is sprayed at the end of the corresponding detection area. This allows employees to trace and check the area ahead through the color mark in subsequent processes, realizing visual monitoring and problem tracing of the glue application status.

[0026] Based on the above structure, the glue application rate monitoring method of the present invention is as follows: After the glue bucket 1 is placed on the outer tray 21, the operator first completes the initial calibration through the controller. The controller records the total weight of the glue bucket 1 and the glue liquid transmitted by the weighing sensor 24 at this time, as the reference value for subsequent calculations. The controller establishes communication connections with the weighing sensor 24, the delivery pump 61, the motor 651 of the marking assembly 65, and the encoder of the roller 601, respectively, and receives the status signals of each component in real time and sends control commands.

[0027] During the feeding of the base paper 7, the encoder installed on the roller 601 collects the paper feeding length data in real time and transmits it to the controller. When the controller determines that the base paper 7 has passed the set detection area length, it immediately defines a new detection area and simultaneously records the weight change data fed back by the weighing sensor 24 in that area. The controller calculates the total weight of glue reduced by the glue bucket 1 in that detection area by the difference between the initial weight and the real-time weight. Combined with the preset fixed width of the base paper 7, the controller calculates the area of ​​the detection area and then obtains the average glue application amount in that area. Afterwards, the controller compares the calculation result with the preset qualified application amount. The glue application range is compared, and the position of the end of the detection area is tracked in real time through encoder data. When the end moves to the printing position corresponding to the marking component 65, the controller issues an instruction based on the judgment result: if the glue application amount is within the qualified range, the marking is not started; if the glue application amount is insufficient, the controller drives the marking spray gun 654 to spray a red color mark 71 upwards, and sprays the color mark 71 at the edge position of the end of the detection area of ​​the set length; if the glue application amount is excessive, the controller controls the marking spray gun 654 to spray a yellow color mark 71, and the color mark represents the area of ​​the set length in front of it as the glue application problem area.

[0028] It should be noted that, in addition to the core data processing and command issuance functions, the controller also has practical functions such as parameter setting, data storage, and anomaly alarms. Operators can input basic parameters such as the fixed width of the base paper 7, the length of the detection area, and the acceptable glue application range through the controller's interface to adapt to different production requirements. During monitoring, the controller automatically stores the glue application data for each detection area, along with the corresponding color mark printing time and location information, facilitating retrospective retrieval in case of quality issues. When components such as the weighing sensor 24 and encoder exhibit abnormal signals, or when the glue supply pressure of the delivery pump 61 is unstable, the controller will immediately trigger an audible and visual alarm and suspend the operation of the glue spraying assembly 6 to prevent the continuous generation of unqualified glue application areas. Simultaneously, it will mark abnormal nodes in the stored data, providing a basis for equipment maintenance.

[0029] It should be noted that color code 71 is a key identifier connecting glue application monitoring data with subsequent processes. Its function is to intuitively convey the glue application status and the location information of the problem area, making it convenient for employees to quickly identify and trace. In practical applications, a directional design with numbers can be adopted, which retains the color indication function and clarifies the scope of the problem through numbers and orientation.

[0030] The specific numerical value represents the length of the corresponding detection area. For example, if the detection area is set to 50 centimeters, the number for color mark 71 would be "50". The color of the number directly corresponds to the glue application status; the number is red when the glue application is insufficient and yellow when it is excessive. The orientation of the number is opposite to the paper feed direction, meaning the first digit of the number "50" points towards the detection area. After seeing color mark 71, employees can quickly locate the glue application area 50 centimeters in front of them by following the orientation of the number. The printing parameters of color mark 71 are preset and precisely controlled by the controller. After calculating the glue application result, the controller will simultaneously send color, number, and printing angle instructions to the marking gun 654 to ensure that color mark 71 is clear and the information is accurate. This allows subsequent quality inspection or cutting processes to directly locate the problem area through color mark 71 without repeatedly checking the data.

[0031] As one of the preferred embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the first buffer 3 includes an outer sleeve 32 that passes through the inner tray 22, a sliding post 31 disposed inside the outer sleeve 32 and connected at its upper end to the lower surface of the outer tray 21, and a bottom cover 33 disposed at the lower end of the outer sleeve 32. A first spring 321 is sleeved on the outside of the outer sleeve 32. The two ends of the first spring 321 abut against the outer tray 21 and the inner tray 22 respectively. A first sealing ring 311 is disposed between the sliding post 31 and the outer sleeve 32 and sleeved on the outside of the sliding post 31.

[0032] The first buffer 3 is installed between the outer tray 21 and the inner tray 22 and is an important anti-interference structure in the weighing detection assembly 2. The outer sleeve 32, which runs through the inner tray 22, serves as the core mounting carrier. The upper end of the sliding column 31 inside the outer sleeve 32 is directly connected to the lower surface of the outer tray 21, allowing the pressure transmitted from the rubber bucket 1 through the outer tray 21 to be introduced into the inner sleeve 32. The two ends of the first spring 321 on the outside of the outer sleeve 32 abut against the outer tray 21 and the inner tray 22 respectively, which can initially buffer the pressure fluctuations transmitted from the outer tray 21. The first sealing ring 311 on the outside of the sliding column 31 fits tightly against the inner wall of the outer sleeve 32, ensuring the airtightness of the inner sleeve 32 and preventing air leakage from affecting the buffering effect. This allows the weight of the rubber bucket 1 to be transmitted more smoothly through the outer tray 21 and the sliding column 31, providing a stable pressure signal for the weighing sensor 24.

[0033] As one of the preferred embodiments of the present invention, such as Figure 1 and Figure 3As shown, a boss 331 that mates with the lower end of the outer sleeve 32 is provided at the center of the upper surface of the bottom cover 33. The boss 331 is placed inside the lower end of the outer sleeve 32. A one-way air valve 332 that can vent air into the inner part of the outer sleeve 32 is provided inside the boss 331. A second sealing ring 334 that is sleeved on the outside of the one-way air valve 332 is provided between the one-way air valve 332 and the boss 331. An air hole 333 that communicates with the one-way air valve 332 is provided through the bottom of the bottom cover 33. A sealing ring 335 is installed on the upper surface of the bottom cover 33. A sealing groove 336 that mates with the sealing ring 335 is provided on the lower end surface of the outer sleeve 32.

[0034] Furthermore, in the above structure, guide rods 34 are symmetrically arranged on both sides of the outer sleeve 32. The lower end of the guide rod 34 passes through the inner tray 22 and is connected to the bottom cover 33. A top plate is provided at the upper end of the guide rod 34. A second spring 35 is provided between the inner tray 22 and the top plate and sleeved on the outside of the guide rod 34.

[0035] The bottom cover 33 fits tightly with the outer sleeve 32. The boss 331 on the upper surface of the bottom cover 33 fits perfectly into the lower end of the outer sleeve 32. Together with the sealing ring 335 on the bottom cover 33 and the sealing groove 336 on the outer sleeve 32, it can effectively enhance the internal sealing of the outer sleeve 32 and prevent air leakage from affecting the effect during the cushioning process. The one-way air valve 332 inside the boss 331 only allows air to flow into the inner part of the outer sleeve 32. The second sealing ring 334 ensures the seal between the one-way air valve 332 and the boss 331. The air hole 333 at the bottom of the bottom cover 33 provides a channel for gas flow, ensuring that external air can stably enter the outer sleeve 32 when the glue bucket 1 is reduced in weight.

[0036] The guide rods 34 on both sides of the outer sleeve 32 further enhance the cushioning stability. Their lower ends pass through the inner tray 22 and are fixed to the bottom cover 33, while the top plate at the upper end restricts the displacement of the guide rods 34. The second spring 35 between the inner tray 22 and the top plate is sleeved on the guide rods 34. When the glue bucket 1 applies pressure to press down the outer tray 21, the guide rods 34 move synchronously with the bottom cover 33, and the second spring 35 assists the first spring 321 in cushioning the pressure. When the pressure decreases, the second spring 35 can drive the bottom cover 33 to return to its original position, allowing the outer sleeve 32 and the bottom cover 33 to re-fit and seal.

[0037] As one of the preferred embodiments of the present invention, such as Figure 1 and Figure 4As shown, the lifting support 4 includes a support cylinder 41, an mounting cylinder 42 disposed at the upper end of the support cylinder 41, and a first lead screw 43 disposed within the support cylinder 41 and the mounting cylinder 42. The upper end of the first lead screw 43 is connected to the base 23, and the lower end of the first lead screw 43 is placed inside the support cylinder 41. Guide grooves 411 are symmetrically arranged on the inner wall of the support cylinder 41. A guide block 431 that can slide within the guide groove 411 is disposed at the lower end of the first lead screw 43. A first threaded sleeve 44 is disposed inside the mounting cylinder 42. The first threaded sleeve 44 is sleeved on the first lead screw 43. A pad block 441 is disposed below the first threaded sleeve 44. A rotating rod 442 is symmetrically connected to the top of the first threaded sleeve 44.

[0038] The lifting supports 4 are symmetrically distributed on the lower surface of the base 23. Height adjustment ensures the weighing detection assembly 2 remains level, providing a stable working environment for the load cell 24. The support cylinder 41 serves as the bottom support structure, while its upper mounting cylinder 42 provides installation space for the adjustment components. The upper end of the first lead screw 43, which runs through both, is directly connected to the base 23 and is a key component for transmitting adjustment actions. The guide groove 411 on the inner wall of the support cylinder 41 engages with the guide block 431 at the lower end of the first lead screw 43, restricting the rotation of the first lead screw 43 and allowing it to move vertically only, preventing offset during adjustment.

[0039] The first threaded sleeve 44 inside the mounting cylinder 42 is threadedly connected to the first lead screw 43. The pad 441 below the sleeve enhances the installation stability of the first threaded sleeve 44 and prevents it from shaking during rotation. When height adjustment is required, the operator only needs to rotate the rotating rod 442 symmetrically connected to the top of the first threaded sleeve 44 to drive the first threaded sleeve 44 to rotate around its own axis. Under the action of the thread and the limit of the guide block 431, the first lead screw 43 will rise or fall synchronously with the rotation of the sleeve, thereby driving the corresponding end of the base 23 to adjust its height, ultimately keeping the entire weighing and detection assembly 2 in a horizontal state, avoiding weight transmission deviation of the rubber bucket 1 due to tilting, and ensuring the accuracy of the weighing data.

[0040] As one of the preferred embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the second buffer 5 includes a fixed cylinder 51 disposed outside the pressure column 221 and connected at its lower end to the upper surface of the base 23, and a hook spring 53 symmetrically disposed between the fixed cylinder 51 and the pressure column 221 and inclined downward. The two ends of the hook spring 53 are hooked to the mounting base 52, and the two ends of the hook spring 53 are respectively connected to the fixed cylinder 51 and the pressure column 221 through the mounting base 52.

[0041] The fixing cylinder 51 is fitted over the pressure column 221, with its lower end fixed to the upper surface of the base 23, providing a mounting base for the entire buffer structure. Symmetrically distributed hook springs 53 are inclined downwards and connected to the fixing cylinder 51 and pressure column 221 via mounting seats 52 at both ends. This connection method provides a stable pulling force to the pressure column 221 from both sides. When the weight of the glue bucket 1 is transferred to the pressure column 221 via the inner tray 22, the pressure column 221 generates downward pressure. The hook springs 53 then undergo elastic deformation, dispersing and buffering the concentrated pressure, preventing a sudden increase in pressure from impacting the weighing sensor 24. Even as the weight of the glue bucket 1 gradually decreases with glue application, the hook springs 53 slowly return to their original position, allowing the pressure on the weighing sensor 24 to decrease smoothly. This, combined with the first buffer component 3, further improves the accuracy of the weighing data.

[0042] As one of the preferred embodiments of the present invention, such as Figure 2 and Figure 6 As shown, the glue spraying assembly 6 also includes a roller 601 arranged along the material feeding direction and rotatably connected to the frame 60, a support rod 62 connected to the frame 60 at both ends, and a fixed seat 63 fixedly sleeved on the outside of the support rod 62. The glue spraying nozzles 64 are installed on the lower surface of the fixed seat 63 and are evenly spaced along the length of the fixed seat 63. The glue spraying nozzles 64 are oriented downwards.

[0043] The glue spraying assembly 6 has a roller 601 rotatably connected to the frame 60 along the material feeding direction. Support rods 62, fixed at both ends to the frame 60, are connected to a fixed base 63 via an external fixed sleeve. Glue spray nozzles 64 are stably mounted on the fixed base 63. The glue spray nozzles 64 are mounted on the lower surface of the fixed base 63 and are evenly spaced along the length of the fixed base 63, adapting to the width of the packaging paper and ensuring a uniform glue application area on the packaging paper. The glue spray nozzles 64 are oriented downwards, allowing them to directly target the packaging paper conveyed on the lower roller 601. Combined with the glue delivered from the glue tank 1 by the delivery pump 61 through the delivery pipe, the glue can be accurately and evenly sprayed onto the packaging paper, meeting the glue application quality requirements of subsequent production.

[0044] It should be noted that an encoder (not shown) is installed on the roller 601 used to convey the base paper 7. The encoder is installed on the roller shaft of the roller 601 and rotates synchronously with the roller 601 to monitor the conveying length of the base paper 7 in real time.

[0045] As one of the preferred embodiments of the present invention, such as Figure 2 and Figure 6As shown, the marking assembly 65 includes a second lead screw 652 rotatably mounted on a frame 60, a motor 651 mounted on the frame 60 and connected to one end of the second lead screw 652, and a second threaded sleeve 653 sleeved on the second lead screw 652. A marking spray gun 654 is provided on the upper surface of the second threaded sleeve 653, and the marking spray gun 654 is oriented upward.

[0046] The second lead screw 652 of the marking assembly 65 is rotatably mounted on the frame 60, with one end connected to a motor 651 mounted on the frame 60. The motor 651 provides stable power for the rotation of the lead screw. The second threaded sleeve 653, fitted onto the second lead screw 652, moves along the axial direction with the rotation of the lead screw, thereby adjusting the position of the marking spray gun 654 above it to adapt to the needs of different widths of packaging paper or gluing areas. The marking spray gun 654 is set upwards so that it can be directly aimed at the bottom surface of the packaging paper conveyed by the roller 601 below, facilitating accurate printing of color marks 71. When the weighing sensor 24 collects the weight data of the glue bucket 1, and the system calculates the amount of glue applied to a certain area N, if it is insufficient or excessive, the motor 651 will drive the second lead screw 652 to rotate, moving the marking spray gun 654 to the corresponding position and printing a red or yellow color mark 71 at the edge of the end of the area, allowing subsequent process workers to quickly locate and check the problem area ahead by using the color mark.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
