Description
Technical Field
[0001] The present invention belongs to the technical field of new energy and relates to a liquid-cooled gluing device. Background Art
[0002] In the technical field of new energy, the liquid-cooled gluing process is a key link in the production of battery modules, and its quality directly affects the battery heat dissipation performance and long-term reliability. Traditional gluing devices mostly adopt single-axis or simple multi-axis drive structures, relying on manual adjustment of the gluing path and positioning parameters, which have significant technical bottlenecks. On the one hand, the motion trajectory accuracy of the gluing head is limited by the insufficient rigidity of the transmission structure and mechanical clearances. Especially when coating complex curved surfaces or high-precision patterns, problems such as trajectory deviation and uneven glue layer thickness are likely to occur. On the other hand, real-time quality monitoring during the gluing process is lacking. Operators need to judge the glue liquid state through off-line sampling inspection and cannot correct defects such as broken glue and overflow glue in time, resulting in difficulty in ensuring product consistency. In addition, the automation level of existing devices is relatively low. Product positioning depends on manually adjusting the position of the trolley, and height calibration requires repeated trial and error, with low efficiency and easy introduction of human errors. Although some devices attempt to introduce vision detection systems, limited by fixed light sources and single shooting angles, image acquisition often fails due to uneven illumination or reflection interference under complex working conditions, making it difficult to achieve accurate online quality feedback. These technical defects seriously restrict the stability of the gluing process and the large-scale production efficiency. Summary of the Invention

[0027] The present invention provides Figures 1 to 8 In an embodiment of the present invention, a liquid-cooled glue coating device includes: A frame 1, wherein a working area 11 is provided in the frame 1, and a gantry 12 is provided on the frame 1; A conveying mechanism 2, wherein the conveying mechanism 2 is used to convey the product to the working area 11; A multi-axis driving mechanism 3, wherein the multi-axis driving mechanism 3 comprises a horizontal driving module 31 and a vertical driving module 32, wherein the horizontal driving module 31 is arranged on the gantry 12, and the vertical driving module 32 is transmission-connected to the horizontal driving module 31; A gluing mechanism 4, wherein the gluing mechanism 4 is drivingly connected to the vertical driving module 32; The camera mechanism 5 is arranged at the side of the glue coating mechanism 4 and is used to align with the output end of the glue coating mechanism 4 to collect the glue coating image in real time.
[0028] Specifically, the frame 1 adopts a welded steel structure framework, with a rectangular working area 11 inside. The gantry 12 spans across the top of the working area 11 and is composed of two columns and a crossbeam. The bottoms of the columns are fixed to both sides of the frame 1 by bolts, and a horizontal guide rail is laid on the surface of the crossbeam. Among them, the entrance of the working area 11 is wide and then gradually shrinks, and is parallel in the gluing area. This enables the conveying module to smoothly transition along the tapered channel to the parallel conveying section when entering the working area 11; the conveying mechanism 2 includes a conveying structure arranged in the working area 11 and a conveying vehicle for receiving products. The two cooperate with each other to enable the products to be conveyed to the center of the working area 11; the horizontal driving module 31 includes an X-axis linear module and a Y-axis linear module. The crossbeam of the gantry 12 is laid on the Y-axis linear module and is slidably connected to it. The X-axis linear module is laid along the crossbeam of the gantry 12. The Y-axis linear module drives the X-axis linear module to move along the Y-axis direction, and the X-axis linear module drives the gluing mechanism 4 to move along the X-axis. The vertical driving module 32 is arranged on the X-axis linear module and is slidably connected to it. It is connected to the gluing mechanism 4 through a slider and drives it to lift and lower in the vertical direction; the gluing mechanism 4 is fixed to the end of the vertical driving module 32, and the glue outlet direction faces the working area 11. The imaging mechanism 5 is installed on the side of the gluing mechanism 4 through a bracket, and the lens axis is parallel to the glue outlet. The imaging mechanism 5 is connected to the PLC controller through a data cable to capture the image of the gluing area in real time.
[0029] Specifically, the working process of this embodiment is as follows: After the conveying structure sends the product to the center of the working area 11, it stops. The X / Y axes of the horizontal driving module 31 move in coordination to drive the gluing mechanism 4 to move along a preset path; the vertical driving module 32 adjusts the height of the gluing mechanism 4 to ensure a constant distance between the nozzle and the product surface. The gluing mechanism 4 outputs A / B glue in proportion, and the glue applicator head of the gluing mechanism 4 evenly coats along the trajectory; the imaging mechanism 5 captures the shape of the glue layer in real time, and the image data is fed back to the control system to dynamically correct the gluing speed or the glue output volume. After gluing is completed, the multi-axis driving mechanism 3 resets to the initial position, and the conveying mechanism 2 removes the product to prepare for the next operation cycle.
[0030] In summary, due to the lack of multi-axis coordinated driving and real-time visual feedback in traditional gluing equipment, there are problems such as low accuracy of the gluing path and insufficient automation, resulting in deviation of the gluing trajectory, uneven glue layer thickness, and inability to dynamically monitor the gluing quality, affecting product consistency and process stability. This embodiment realizes high-precision motion control of the gluing mechanism 4 in three-dimensional space through an integrated liquid-cooled gluing equipment integrating the multi-axis driving mechanism 3 and the imaging mechanism 5, and at the same time, it collects the gluing images in real time and feeds them back to the control system to dynamically correct the gluing parameters, improving the gluing accuracy and quality monitoring ability.
[0031] The conveying mechanism 2 includes: rollers 21, and the rollers 21 are arranged on both sides of the entrance of the working area 11; A trolley 22, wherein a sliding structure 223 cooperating with the roller 21 is provided at a side end of the trolley 22, and the trolley 22 is used to carry products; A lifting structure 23, wherein the lifting structure 23 is disposed in the working area 11, and the lifting direction of the lifting structure 23 is the vertical direction of the cart 22; A height positioning block 24 is installed on the trolley 22. The height positioning block 24 and the lifting structure 23 match each other. The interaction between the lifting structure 23 and the height positioning block 24 is used to complete the height adjustment of the product.
[0032] In this embodiment, the rollers 21 are arranged in pairs on both sides of the entrance of the working area 11, serving as a guide structure for the sliding of the cart 22, wherein the cart 22 can be manually pushed into the working area 11, and the rollers 21 assist the movement of the cart 22, or a motor driving the rollers 21 can be installed in the frame 1, and the rotation of the rollers 21 drives the position of the cart 22, driving the cart 22 into the working area 11; a sliding structure 223 cooperating with the rollers 21 is provided at the side end of the cart 22, and the sliding structure 223 can be a sliding groove or a guide rail, and the height of the sliding structure 223 can be the same as the position of the rollers 21, and the width of the sliding structure 223 can be greater than the rollers 21, so as to facilitate the rollers 21 and the cart 2 2 contact, convenient for assisting or actively driving the cart 22 to enter the working area 11; the lifting structure 23 is fixed to the side wall of the working area 11, the lifting direction is vertically upward, and the top is provided with a slot or contact surface matching the height positioning block 24, wherein the lifting power of the lifting structure 23 can be selected from a cylinder, a servo motor or a hydraulic cylinder; the height positioning block 24 is fixed to the bottom or side end of the plane of the cart 22 for carrying the product, and its shape (such as a boss or a groove) corresponds to the lifting structure 23. After the two are in contact, the height of the cart 22 is adjusted by the lifting action of the lifting structure 23, thereby realizing product positioning. Preferably, the height positioning block 24 can be set to a magnetic suction type or a slide rail adjustment type to meet the needs of different environments; Furthermore, a cart 22 positioning system and an up-and-down height positioning system are also provided in the working area 11, wherein the cart 22 positioning system includes an infrared transmitter and a receiver, which are arranged on both sides of the entrance of the working area 11, and the infrared rays cover the entrance area laterally. When the cart 22 enters, the infrared signal is blocked or reconnected after being blocked, triggering a position detection signal to control the roller 21 to pause and start the lifting process; further, the up-and-down height positioning system consists of two sets of diagonally arranged infrared transmitters and receivers, which are installed at diagonal positions on the same horizontal plane of the working area 11 (such as the left front wall and the right rear wall). When the lifting structure 23 pushes the cart 22 to move upward, the upper end surface of the cart 22 gradually blocks the infrared beam; when the cart 22 rises to the target height, its height positioning block 24 is completely matched with the card slot of the lifting structure 23, the upper end surface of the cart 22 is out of the infrared blocking area, the beam is reconnected, triggering the lifting structure 23 to stop the action, and completing the height locking.
[0033] More specifically, one working process of the conveying mechanism 2 of the liquid-cooled glue coating equipment is as follows: the cart 22 slides into the working area 11 through the rollers 21 on both sides of the entrance of the working area 11, and the rollers 21 are manually pushed or driven by a motor to assist the cart 22 to move forward; when the cart 22 enters, the infrared cart 22 positioning system at the entrance detects a blocking signal of the cart 22, triggering the rollers 21 to pause and start the lifting process; the lifting structure 23 lifts the cart 22 vertically upward, and at the same time, the infrared up and down height positioning system set diagonally in the working area 11 detects the cart 22 in real time. 2 Change in the height of the upper end surface - When the cart 22 gradually blocks the diagonal infrared beam during its ascent, the lifting structure 23 continues to move; until the cart 22 reaches the target height, its bottom height positioning block 24 is completely matched with the card slot of the lifting structure 23, at this time, the upper end surface of the cart 22 is out of the infrared blocking area, the infrared beam is reconnected, and the lifting structure 23 stops immediately, completing the product height locking; finally, the cart 22 is fixed by the card connection between the height positioning block 24 and the lifting structure 23, ensuring that the product is in a precise positioning state, providing a basis for the subsequent gluing process.
[0034] In summary, the conveying mechanism 2 of the existing liquid-cooled gluing equipment relies on manual positioning, and has the problems of low positioning accuracy and poor efficiency. In particular, the product height adjustment requires multiple manual operations, which can easily lead to deviations in the gluing position and affect the process quality. In this embodiment, the conveying mechanism 2 of the roller 21, the trolley 22, the lifting structure 23 and the height positioning block 24 are combined through the integrated infrared detection positioning system of the trolley 22 and the upper and lower height positioning system to realize the automation of product conveying and height adjustment. After the trolley 22 slides along the roller 21 into the working area 11, the lifting structure 23 cooperates with the height positioning block 24 to automatically complete the vertical positioning of the product, reduce manual intervention, and improve accuracy and efficiency.
[0035] A cylinder positioning baffle 13 is provided at the depth of the working area 11 . When the trolley 22 moves along the rollers 21 to the depth of the working area 11 , the cylinder positioning baffle 13 contacts the trolley 22 , limiting the further forward movement of the trolley 22 .
[0036] The cart 22 is provided with a product positioning plate 221 and a product positioning block 222, and the product positioning plate 221 and the product positioning block 222 are detachably connected to the upper side of the cart 22. The position of the product positioning plate 221 on the cart 22 is adjusted by adjusting the position of the product positioning block 222 on the cart 22 to abut against the product positioning plate 221.
[0037] In this embodiment, the cylinder positioning baffle 13 can be made of metal sheet or high-strength composite material, with a buffer layer (such as a rubber pad) on its surface. It is hinged to the side wall of the frame 1 through a rotating shaft and can swing around the shaft. Further, a cylinder driving assembly is also provided inside the frame 1. The cylinder driving assembly includes a cylinder and a solenoid valve. The cylinder body is fixed to the side wall of the frame 1, and the end of the piston rod is hinged to the back of the baffle, driving the baffle to switch between the "horizontally extended" and "vertically retracted" states. Preferably, the cylinder can be replaced by a servo electric push rod to achieve precise control of the baffle extension speed and stroke. The cylinder positioning baffle 13 can be designed as a folding type or a multi-stage telescopic type to reduce the occupied space in the retracted state. A spring damper or an air cushion structure is added to the contact surface between the cylinder positioning baffle 13 and the trolley 22 to reduce the collision impact; Specifically, the trolley 22 slides into the working area 11 along the rollers 21. When its front end moves deep into the working area 11, the trigger sensor detects that the trolley 22 has reached the preset position and sends a signal to the solenoid valve to control the extension of the cylinder piston rod; the cylinder drives the baffle to change from the vertically retracted state to the horizontally extended state. After the baffle is fully unfolded, it is in close contact with the front end of the trolley 22, forcibly restricting the further forward movement of the trolley 22; after positioning, the lifting structure 23 and the height adjustment system are started, and the baffle remains in the extended state until the gluing process is completed; during reset, the cylinder retracts the piston rod, and the baffle vertically resets to the side wall of the frame 1 to avoid interfering with the withdrawal of the trolley 22. In summary, after the trolley 22 of the existing liquid-cooled gluing equipment enters the working area 11, it lacks an end limit structure and only relies on manual judgment of the stop position. It is easy to cause excessive forward movement due to the inertia of the trolley 22 or positioning errors, resulting in the risk of collision between the product and the gluing mechanism 4 or positioning deviation, affecting the gluing accuracy; in this embodiment, a cylinder-driven positioning baffle is provided deep in the working area 11, combined with the trolley 22 movement trigger mechanism, to achieve automatic hard limit of the end position of the trolley 22. When the trolley 22 moves along the rollers 21 to the set end point, the cylinder positioning baffle 13 extends and contacts the trolley 22, forcibly preventing its forward movement, ensuring that the trolley 22 accurately docks, and providing a stable basis for subsequent height adjustment and gluing.
[0038] The trolley 22 is provided with a product positioning plate 221 and a product positioning block 222. The product positioning plate 221 and the product positioning block 222 are detachably connected to the upper side of the trolley 22. By adjusting the position of the product positioning block 222 on the trolley 22 to abut against the product positioning plate 221, the position of the product positioning plate 221 on the trolley 22 is adjusted.
[0039] In this embodiment, the mounting holes or mounting grooves can be arranged in a matrix or linearly on the upper surface of the trolley 22. The hole pitch is designed according to product specifications and standardized to adapt to the mounting requirements of different positioning blocks. The product positioning plate 221 can be a rectangular or L-shaped metal plate and is detachably connected to the preset mounting holes / grooves on the upper surface of the trolley 22 through bolts or pins. The mounting holes are evenly distributed along the length direction of the trolley 22. The product positioning block 222 can be a cuboid or a wedge-shaped block, and a bolt or pin interface matching the mounting holes / grooves on the upper surface of the trolley 22 is provided at the bottom, and it is detachably connected to the trolley 22 by tightening the bolts or inserting the pins; a rubber buffer layer can be added to the side end of the positioning block to avoid hard collision when abutting against the product positioning plate 221; preferably, an adjustable ejector rod can be provided on the side of the product positioning block 222 facing the product positioning plate 221, and the clamping force can be finely adjusted through a threaded knob to ensure firm fixation of the product. A slide rail or a T-shaped mounting groove can also be added to the upper surface of the trolley 22, and the bottom of the product positioning block 222 is changed to a slider structure, which is locked after adjusting the position by sliding to improve the adjustment efficiency.
[0040] Specifically, according to the product size requirements, the operator fixes the product positioning plate 221 on the preset mounting holes of the trolley 22 through bolts or pins; selects a suitable mounting hole / groove, and connects the product positioning block 222 to the target position on the surface of the trolley 22 through bolts or pins; adjusts the product positioning block 222 to make it abut against the product positioning plate 221 to form a clamping area.
[0041] In summary, the trolley 22 of the existing liquid-cooled gluing equipment lacks a positioning structure that can flexibly adapt to products of different sizes. After the product positioning plate 221 is fixedly installed, it cannot be adjusted, and the entire trolley 22 needs to be replaced or manually disassembled and reorganized, resulting in low efficiency and difficulty in ensuring the positioning accuracy of multiple models of products. In this embodiment, by providing a detachable product positioning plate 221 and a product positioning block 222 on the trolley 22, and using the combined adjustment of the two, the requirements of quickly adapting to products of different specifications are realized. By adjusting the mounting position of the product positioning block 222 on the trolley 22 and abutting against the product positioning plate 221, a variable positioning area is formed, and the precise control of the product fixing range can be completed without replacing the trolley 22.
[0042] The horizontal drive module 31 includes a first drive module 311 and a second drive module 313; The first drive module 311 and the second drive module 313 are arranged on the gantry. The first drive module 311 and the second drive module 313 are in transmission connection. The first drive module 311 drives the second drive module 313 to move the gluing mechanism 4 in the vertical direction; The vertical drive module 32 and the second drive module 313 are in transmission connection. The second drive module 313 drives the vertical drive module 32 to move the gluing mechanism 4 in the horizontal direction.
[0043] The drive structure of the traditional liquid-cooled glue coating equipment has problems such as large mechanical clearance and insufficient transmission rigidity, resulting in difficult satisfaction of the motion accuracy requirements of the glue coating mechanism 4 in the horizontal (X-axis) and vertical (Y-axis) directions for high-complexity glue coating paths. Especially in high-frequency commutation or high-speed movement, cumulative errors are likely to occur, affecting the uniformity of the glue layer. To solve the above problems, in this embodiment, a high-precision horizontal drive module 31 directly driven by a servo motor is adopted. Through the coordinated control of the first drive module 311 and the second drive module 313, the precise movement of the glue coating mechanism 4 in the vertical (Y-axis) and horizontal (X-axis) directions is respectively realized. Combining with the closed-loop feedback system of the servo motor, the mechanical transmission clearance is eliminated, and the repeat positioning accuracy and dynamic response speed of the motion trajectory are improved.
[0044] The horizontal drive module 31 includes a first drive module 311 (Y-axis) and a second drive module 313 (X-axis). The first drive module 311 can be composed of a servo motor, a ball screw, and a linear guide. The servo motor is connected to the ball screw through a coupling. Both ends of the ball screw are fixed to the vertical beam of the gantry through bearing seats, and its nut seat is rigidly connected to the second drive module 313, driving the second drive module 313 to move along the Y-axis direction; the second drive module 313 can be composed of a servo motor, a synchronous belt transmission mechanism, and a linear guide. The servo motor is installed at the end of the cross beam and drives the vertical drive module 32 to move horizontally (X-axis) along the linear guide on the cross beam through the synchronous belt; further, the first drive module 311 can also be composed of a servo motor, a synchronous belt transmission mechanism, and a linear guide, and the second drive module 313 can also be composed of a servo motor, a ball screw, and a linear guide. The first drive module 311 can also use a linear motor to replace the ball screw to further reduce the intermediate transmission link and improve the dynamic performance. The synchronous belt transmission can be replaced by a high-precision ball screw or a magnetic levitation guide to adapt to different load and precision requirements. The servo motor can be integrated with an absolute encoder to achieve full closed-loop control and further improve the position feedback accuracy. The ultimate purpose of the above structure is to make the first drive module 311 drive the second drive module 313 to move along the Y-axis, and the second drive module 313 drives the vertical drive module to move along the X-axis, and the two are linked to realize the composite movement of the glue coating mechanism 4 in the horizontal plane.
[0045] In this embodiment, the servo motor of the first drive module 311 receives the control system instruction to move the second drive module 313 to the target longitudinal position along the Y-axis linear guide. The servo motor of the second drive module 313 starts to drive the vertical drive module 32 to move horizontally to the preset coordinate along the X-axis linear guide of the cross beam. Further, the two-axis servo motors run synchronously based on the coordinate data of the preset glue coating path, and the position deviation is corrected in real time through closed-loop feedback to ensure that the glue coating mechanism 4 moves precisely according to the planned trajectory. After the glue coating is completed, the two drive modules drive the glue coating mechanism 4 to return to the initial position to prepare for the next operation cycle.
[0046] The vertical driving module 32 includes: A vertical mounting bracket 321, the camera mechanism 5 is mounted on the vertical mounting bracket 321, one side of the vertical mounting bracket 321 is transmission-connected to the second driving module 313, and the other side of the vertical mounting bracket 321 is slidingly connected to the glue coating mechanism 4; The third driving module 322 is installed on the vertical mounting bracket 321 , and the third driving module 322 drives the glue coating mechanism 4 to move in the vertical direction.
[0047] In this embodiment, the vertical mounting bracket 321 can be made of high-strength aluminum alloy profile, one side of which is slidably connected to the crossbeam of the second drive module 313 (X-axis drive module) through a slider, and the other side is slidably connected to the glue coating mechanism 4 through a linear guide or a slide rail to form a vertical motion guide structure. The third drive module 322 can be composed of a servo motor, a ball screw and a linear guide. The servo motor is connected to the ball screw through a coupling, and both ends of the ball screw are fixed to the vertical beam of the vertical mounting bracket 321 through bearing seats. Its nut seat is rigidly connected to the glue coating mechanism 4 to drive the glue coating mechanism 4 to move along the Z-axis direction; the visual camera lens mounting plate 51 is fixed to the side of the vertical mounting bracket 321 by bolts, and the lens axis of the CCD camera 52 is parallel to the glue outlet of the glue coating mechanism 4 to ensure real-time acquisition of the glue coating area image; further, the third drive module 322 can use a linear motor instead of a ball screw to further reduce the length of the transmission chain and improve the dynamic response speed. The servo motor can be integrated with a high-resolution absolute encoder to achieve full closed-loop position feedback.
[0048] Specifically, the working process of the vertical drive module 32 is as follows: the servo motor receives the Z-axis target coordinates issued by the control system, and drives the gluing mechanism 4 to rise and fall along the preset path (guide rail or slide groove, etc.) on the vertical mounting bracket 321 to a set height. During the movement of the gluing mechanism 4, the CCD camera 52 fixed to the vertical mounting bracket 321 takes a real-time image of the glue outlet position and feeds it back to the control system. After the gluing is completed, the servo motor drives the gluing mechanism 4 to return to the initial height.
[0049] In this embodiment, the high-rigidity vertical drive module 32 directly driven by the servo motor is combined with closed-loop feedback and a rigid guide structure to achieve precise positioning of the glue coating mechanism 4 in the vertical direction, effectively avoiding the vibration and offset problems of the traditional transmission method and ensuring the consistency of the glue layer thickness.
[0050] The glue coating mechanism 4 comprises: A glue valve mounting plate 41, wherein the glue valve mounting plate 41 is fixed to the end of the vertical drive module 32; The first glue inlet pipe 42 and the second glue inlet pipe 43, both the first glue inlet pipe 42 and the second glue inlet pipe 43 are arranged on one side of the glue application valve mounting plate 41; A mixing valve 44, the mixing valve 44 is arranged on one side of the glue application valve mounting plate 41, and the first glue inlet pipe 42 and the second glue inlet pipe 43 are respectively connected to two input ends of the mixing valve 44; A glue application pipe 45, the input end of the glue application pipe 45 is arranged at the output end of the mixing valve 44, and the output end of the glue application pipe 45 faces the working area 11.
[0051] In this embodiment, the glue application valve mounting plate 41 can be made of stainless steel or anodized aluminum, fixed to the end of the vertical drive module 32 by bolts, with mounting holes on the surface. The first glue inlet pipe 42 and the second glue inlet pipe 43 are respectively filled with different colloids, and can be connected to the input ends of the mixing valve 44 through quick-release joints. The mixing valve 44 can adopt a static or dynamic mixing structure, fixed to the side of the glue application valve mounting plate 41, and the two input ends are respectively hermetically connected to the first and second glue inlet pipes 43. The output end is connected to the glue application pipe 45. The glue application pipe 45 can be a corrosion-resistant fluororubber pipe, with the input end connected to the mixing valve 44, and the output end extends to the working area 11 and is provided with a replaceable nozzle.
[0052] Specifically, the working process of this embodiment is as follows: 1. Glue mixing: Glue A and glue B are respectively input into the mixing valve 44 through the first and second glue inlet pipes 43. After being fully mixed in the mixing valve 44, they are output through the glue application pipe 45 to the glue application position in the working area 11. 2. Glue output control: During the glue application process, the glue output flow is controlled by adjusting the pneumatic or electric actuator of the mixing valve 44, and the nozzle evenly coats the glue according to the preset trajectory.
[0053] A waste glue box 14 is also provided on the frame 1 for collecting the remaining glue in the non-glue application state.
[0054] Specifically, the body of the waste glue box 14 can be made of corrosion-resistant plastic or stainless steel. The top of the box body is provided with a glue inlet. Preferably, the bottom can be designed as an inclined diversion groove, with the end connected to a drain valve. Removable multi-layer filters can be installed in the box for separating liquid glue and solidified glue blocks.
[0055] In the existing liquid-cooled glue application equipment, in the non-glue application state, the remaining glue in the glue application pipe 45 is likely to drip onto the frame 1 or the working area 11 due to gravity or pressure residue, causing equipment pollution, glue waste, and difficult cleaning. Long-term accumulation may affect the normal operation of the equipment and the glue application quality. In this embodiment, by installing a special waste glue box 14 at a specific position on the frame 1, the remaining glue can be automatically guided into the waste glue box 14 for centralized collection during the standby or glue application intermittent period of the equipment, avoiding glue dripping pollution and simplifying the maintenance process.
[0056] The camera mechanism 5 includes: The vision camera lens mounting plate 51 is installed on the side of the vertical driving module 32; The CCD camera 52 is installed on the vision camera lens mounting plate 51. The lens of the CCD camera 52 is aligned with the output end of the glue application mechanism 4 for collecting images of the glue application area in real time; The lighting mounting and adjusting plates 53 are symmetrically arranged on both sides of the vision camera lens mounting plate 51. Angle adjusting structures are provided on the lighting mounting and adjusting plates 53; The irradiation lamp 54 is installed on the lighting mounting and adjusting plate 53. The irradiation direction is adjusted through the angle adjusting structure for providing light sources for the CCD camera 52.
[0057] Specifically, the vision camera lens mounting plate 51 can be made of aluminum alloy and is fixed to the side bracket of the vertical driving module 32 by bolts. Horizontal or vertical chutes are provided on the surface of the mounting plate for adjusting the horizontal or vertical positions of the CCD camera 52; the CCD camera 52 is fixed in the chute of the vision camera lens mounting plate 51, and the lens is vertically aligned with the glue outlet of the glue application mechanism 4. The built-in network port of the camera is connected to the control system for real-time transmission of image data; the lighting mounting and adjusting plates 53 are symmetrically arranged on both sides of the lens mounting plate. Each side of the adjusting plate is connected to the irradiation lamp 54 by a hinge. An arc-shaped slide rail is provided at the end of the adjusting plate. The irradiation lamp 54 uses a high-brightness LED light source and is installed on the arc-shaped slide rail of the adjusting plate through a slider. The position of the slider is locked by a knob, and the irradiation angle of the LED lamp (adjustable from 0° to 90°) is adjusted by sliding the slider to ensure that the light evenly covers the glue application area.
[0058] In summary, the vision detection system of the existing liquid-cooled glue application equipment lacks a stable light source and the ability to flexibly adjust the shooting angle, resulting in blurred image collection and insufficient contrast in the glue application area. Especially in a complex lighting environment, false detection or missed detection is likely to occur, affecting the accuracy of glue application quality monitoring. In this embodiment, the imaging mechanism 5 integrating an adjustable light source and a fixed CCD camera 52 is used, and the symmetric lighting mounting and adjusting plates 53 and the angle adjusting structure are utilized to realize the dynamic adaptation of the light intensity and angle in the glue application area, ensuring clear and stable image collection; at the same time, the imaging mechanism 5 is directly fixed to the side of the vertical driving module 32 to realize the synchronous linkage of the glue application action and the vision detection.
