Description

Technical Field

[0001] This invention relates to the field of adhesive application technology for automotive lamp assembly, and more specifically, to an adhesive application apparatus for automotive lamp assembly processing. Background Technology

[0002] In the automotive lighting assembly process, sealing adhesive application is a step to achieve a sealed bond between the lamp cover and the lamp housing. This involves creating an annular groove on the mating surface of the lamp housing as an adhesive channel. By continuously applying adhesive into the groove, the lamp cover and the lamp housing are pressed together to form a complete seal, preventing external moisture and dust from entering the lamp body.

[0003] The existing automotive headlight adhesive application uses an automated trajectory application method. A robotic arm drives the application head to move along a preset annular groove trajectory. At the same time, the adhesive supply system controls the amount of adhesive dispensed through an adhesive valve, so that the sealant is continuously filled into the groove. When the application head completes a full circle along the annular groove and returns to the starting point of the trajectory, the adhesive valve closes and, in conjunction with a back suction action, cuts off the adhesive, completing a single application cycle.

[0004] Because the annular groove is a closed trajectory, the starting and ending positions of the adhesive application coincide, posing a risk of adhesive buildup due to overlapping adhesive layers at the beginning and end. Furthermore, after the adhesive application head finishes applying adhesive, the back-suction function can easily draw in air into the adhesive path, causing a sudden increase in the amount of adhesive sprayed or dispensed at the beginning of the next application, further exacerbating the adhesive buildup problem at the junction of the beginning and end. To address these issues, the existing solution involves moving the adhesive application head back and forth in the junction area, using the physical scraping of the nozzle to spread and smooth out the accumulated adhesive.

[0005] However, the improved method of spreading the adhesive by moving the applicator back and forth did not eliminate the problem of adhesive piling up at the beginning and end. On the contrary, the physical scraping between the nozzle and the groove easily carries the adhesive out, causing the groove to overflow. Furthermore, repeated scraping will cause the outer wall of the applicator to continuously adhere to the excess adhesive. After the excess adhesive dries and hardens, it will interfere with the normal dispensing pattern and further reduce the stability of the adhesive. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an adhesive application device for automotive lamp assembly.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adhesive application device for automotive lamp assembly and processing, comprising a worktable.

[0008] The glue application assembly is located on one side of the workbench and is used to apply glue to the inside of the glue groove on the outer ring of the lamp housing.

[0009] A conveyor assembly, located on top of the workbench, is used to support and move the lamp housing.

[0010] The receiving component is located on top of the conveying component and on one side of the lamp housing. The top of the conveying component is also equipped with multiple sets of contoured columns that adapt to the shape of the bottom of the lamp housing. The lamp housing is positioned on top of the multiple sets of contoured columns. The receiving component is fitted to one side of the glue groove on the outer ring of the lamp housing and defines the glue application path.

[0011] The receiving assembly includes a platform disposed on top of the conveying assembly, a material collection mechanism disposed on top of the platform, and a push rod mounted on top of the platform, one end of the push rod being in contact with one side of the material collection mechanism.

[0012] The material collection mechanism includes a glue box and a top box disposed on top of the glue box. The top of the top box has a glue discharge port, and a scraper is hinged to the top of the glue discharge port by a torsion spring.

[0013] When the adhesive applicator applies adhesive along the adhesive groove path, both the starting point and the ending point of the adhesive application are located at the top of the top box. When the adhesive box and the top box are far away from the lamp housing, the scraper scrapes off the excess material by swinging in the opposite direction to one side of the adhesive groove and scraping.

[0014] The present invention is further configured such that: a spring rod is installed on the top of the top box and on both sides of the glue outlet; the top of the scraper is symmetrically provided with insertion holes; the two spring rods are correspondingly provided with the two insertion holes; and one end of the spring rod is engaged with the inside of the corresponding insertion hole.

[0015] The invention is further configured such that: an inclined portion is provided at the top of the outer side wall of the spring rod, and a slotted hook is provided at the bottom of the outer side wall of the spring rod, and the slotted hook is hung inside the corresponding insertion hole.

[0016] The invention is further configured such that: a sloping rail is connected to the top of the platform and below the glue box; a partition is installed on one side of the sloping rail; the top of the partition is inclined and fits against one side of the glue groove; the top of the partition is lower than the height of the glue groove; an inclined surface is provided on the top of the partition; a groove is opened on the top of the inclined surface; a rubber pad is provided on the side of the top box near the lamp housing; the partition is embedded in the middle of the rubber pad; and the rubber pad fills the gap between the lamp housing and the top box.

[0017] The invention is further configured such that: a slide block slides on the top of the inclined rail, the glue box is installed on the top of the slide block, the glue box is set in a vertical position, and a push plate is connected to the output end of the push rod, the push plate is slidably connected to the side wall of the glue box in the vertical direction.

[0018] The present invention is further configured such that a partition is inserted and connected to the top of the top box, and the partition is located at the highest point of the top box.

[0019] The invention is further configured such that: the bottom of the top box is connected to an insertion tube, the outer wall size of the insertion tube is adapted to the inner wall size of the plastic box, the insertion tube is inserted into the inside of the plastic box, and a telescopic cylinder is installed on one side of the plastic box, the piston rod end of the telescopic cylinder is connected to the side wall of the top box.

[0020] The present invention is further configured such that: two bearing seats are symmetrically installed on the top of the conveying assembly, the platform rotates between the two bearing seats, and two top blocks are provided on the top of the conveying assembly, with the two top blocks inserted on both sides of the platform to provide auxiliary support for the top blocks.

[0021] The present invention is further configured such that: the glue application assembly includes a robotic arm mechanism disposed on one side of the worktable, a heating mechanism and a glue application head connected to the output end of the robotic arm mechanism, wherein the output directions of the heating mechanism and the glue application head are staggered.

[0022] The present invention is further configured such that: the conveying assembly includes an electric slide rail mounted on the top of the worktable, a slide table sliding on the top of the electric slide rail, the receiving assembly and the contour column are both mounted on the top of the slide table, two guide rails are symmetrically mounted on the top of the worktable, and the slide table slides on the top of the two guide rails.

[0023] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up a material collection mechanism, the material collection mechanism is located on one side of the lamp housing. During the preparation of the glue application, the material collection mechanism is attached to the side wall of the glue tank. During the glue application process, the starting point and the ending point of the glue application are placed on the top of the material collection mechanism, so that the glue application head first dispenses glue above the material collection mechanism. After the glue dispensing is stable, it enters the glue tank. After completing one round of glue application, it is sucked back and moved back to the top of the material collection mechanism to stop dispensing glue. The unstable glue material at the beginning and end is received outside the glue tank, avoiding the accumulation of glue at the beginning and end in the glue tank to form glue pile and glue overflow at the mouth of the tank.

[0024] (2) By setting a scraper, the scraper is hinged at the glue outlet and locked with a spring rod. When the glue applicator finishes applying glue and moves above the glue outlet, the glue applicator presses down on the scraper to trigger the spring rod to unlock. The scraper swings towards the lamp housing and sticks to the side wall of the glue tank. Then the telescopic cylinder drives the top box to descend. The scraper scrapes off the glue material adhering to the end with the edge of the glue tank as the fulcrum, reducing the accumulation of glue material on the scraper surface and reducing the situation where the glue material is pulled into a string when the material collection mechanism separates from the lamp housing.

[0025] (3) By setting up a partition, the scraper and the inclined surface of the partition cooperate. When the entire material collection mechanism moves down and resets along the inclined rail, the scraper slides relative to the inclined surface of the partition to further scrape off the residual adhesive on the scraper surface. At the same time, during the descent of the top box, the scraper has already performed initial self-cleaning in part of the position using the side wall of the adhesive groove. The combination of the two methods achieves self-cleaning of the scraper, avoiding the hardening of residual adhesive and affecting subsequent use. Attached Figure Description

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0040] Please see Figures 1-11 The present invention provides the following technical solutions: Example 1, see Figure 1 and Figure 2 A gluing device for assembling and processing automotive lights includes a worktable 1, a conveying assembly 3 mounted on the top of the worktable 1, and a lamp housing 6 to be glued placed on the top of the conveying assembly 3. The conveying assembly 3 is used to support and move the lamp housing 6. The specific structure of the conveying assembly 3 is as follows: See Figure 1 and Figure 2 The conveying component 3 includes an electric slide rail 31 installed on the top of the workbench 1. A slide table 33 slides on the top of the electric slide rail 31. The electric slide rail 31 can be a stepper motor linear slide rail slide block module, which is not specifically limited here. The slide table 33 is connected to the slide block of the electric slide rail 31. The slide table 33 is driven by the electric slide rail 31 to slide horizontally. Two guide rails 32 are symmetrically installed on the top of the workbench 1. The slide table 33 slides on the top of the two guide rails 32. During the sliding process, the bottom sides of the slide table 33 are assisted by the guide rails 32 for sliding guidance and support. Multiple sets of contoured columns 5 adapted to the bottom shape of the lamp housing 6 are also installed on the top of the multiple sets of contoured columns 5 for positioning.

[0041] See Figure 1 and Figure 2 A glue application assembly 2 is provided on one side of the workbench 1, and a glue groove 7 is provided on the top outer ring of the lamp housing 6. The glue application assembly 2 is used to apply glue to the inside of the glue groove 7 on the outer ring of the lamp housing 6. The specific structure of the glue application assembly 2 is as follows: See Figure 1 and Figure 2The adhesive application assembly 2 includes a robotic arm mechanism 21 disposed on one side of the workbench 1, and a heating mechanism 22 and an adhesive application head 23 connected to the output end of the robotic arm mechanism 21. The output directions of the heating mechanism 22 and the adhesive application head 23 are staggered. Before the formal adhesive application, the robotic arm mechanism 21 first drives the heating mechanism 22 and the adhesive application head 23 at the end to adjust their posture, switches the heating mechanism 22 to the working position, and moves along the closed path of the adhesive tank 7 to preheat the inner wall of the adhesive tank 7, thereby improving the adhesion performance between the adhesive and the substrate. After preheating, the robotic arm mechanism 21... 1. Rotate the switching station to adjust the glue applicator 23 to the working position. Then, the robot arm mechanism 21 drives the glue applicator 23 to walk along the path of the glue tank 7, while applying glue to the inside of the glue tank 7. After the glue application is completed, that is, when the beginning and end of the glue meet, the glue applicator 23 stops applying glue and starts back suction. Then, the glue applicator 23 moves back and forth at least twice at the beginning and end of the glue meeting position to help spread out the glue overflowing at the beginning and end meeting position. Then, the robot arm mechanism 21 drives the glue applicator 23 to move out of the top of the lamp housing 6 and perform the subsequent lamp cover pressing and assembly operation.

[0042] Specifically, the operator first places the lamp housing 6 to be coated with adhesive on multiple sets of contoured columns 5. Positioning is achieved by matching the contours of the bottom of the lamp housing 6 with the contours of the contoured columns 5, preventing workpiece displacement during the coating process. Then, the electric slide rail 31 drives the slide table 33 to slide horizontally along the guide rail 32, transporting the lamp housing 6 to the coating station. After the lamp housing 6 is in place, the robotic arm mechanism 21 first switches the heating mechanism 22 to the working position, and preheats it along the closed path of the adhesive tank 7, improving the adhesion between the adhesive and the lamp housing 6. After preheating, the robotic arm... Mechanism 21 switches the glue applicator head 23 to the working position. The glue applicator head 23 continuously travels along the path of the glue tank 7 to apply glue, forming a continuous glue layer in the glue tank 7. When the glue is applied to the joint between the first and last ends, the glue applicator head 23 stops dispensing glue and starts back suction. At the same time, it moves back and forth at the joint position at least twice to flatten the glue material that is stacked at the first and last ends, improving the defect of glue piling at the first and last ends. After the glue application is completed, the robot arm mechanism 21 drives the glue applicator head 23 to reset. The lamp housing 6 is transferred to the next work station with the conveying component 3 for lamp cover pressing and assembly, completing the single cycle glue application operation.

[0043] In Example 2, the improved method of spreading the adhesive by reciprocating the glue applicator 23 did not eliminate the problem of glue piling up at the beginning and end. On the contrary, the physical scraping between the glue nozzle and the groove easily carries the glue out, causing glue overflow at the groove. Furthermore, repeated scraping will cause the glue applicator 23 to continuously adhere to the outer wall. After the glue dries and hardens, it will interfere with the normal glue dispensing pattern and further reduce the stability of the glue form.

[0044] Therefore, this embodiment adjusts the start and end points of the adhesive application path to accommodate unstable adhesive materials at the beginning and end, reducing adhesive buildup and overflow issues.

[0045] See Figure 2 and Figure 3A receiving component 4 is installed on the top of the slide table 33 and on one side of the lamp housing 6. The receiving component 4 is fitted to one side of the glue groove 7 on the outer ring of the lamp housing 6 and defines the glue application path. It receives the glue at the beginning and end of the glue application and connects the beginning and end of the glue application path, removing the beginning and end of the glue application path from the path range of the glue groove 7. Before the glue application operation, the receiving component 4 installed on the slide table 33 is tightly fitted to one side wall of the glue groove 7, forming a transition at the beginning and end of the glue application path. It receives the unstable glue at the beginning and end of the glue application outside the glue groove 7, which not only ensures the continuous and uniform glue layer in the glue groove 7, but also avoids the accumulation of glue at the beginning and end. The specific structure of the receiving component 4 is as follows: See Figures 2-4 The receiving assembly 4 includes a platform 42 mounted on top of the conveying assembly 3. A sloping rail 45 is mounted on top of the platform 42, and a slide block 46 slides on top of the sloping rail 45. A material collecting mechanism 44 is mounted on top of the slide block 46 and is vertically positioned. A push rod 47 is mounted on top of the platform 42, and a push plate 48 is connected to the output end of the push rod 47. The push plate 48 slides vertically against the side wall of the glue box 441. When the glue applicator 2 applies glue along the path of the glue groove 7, both the starting and ending points of the glue application are located on top of the material collecting mechanism 44. Before applying glue, the operator first uses the electric slide rail 31 to drive the slide table 33 and the receiving assembly 4 to move together. At the glue application station, the worker pushes the handle of push rod 47. Push rod 47 applies a pushing force to the material collection mechanism 44 through push plate 48, causing slide 46 to slide upward along inclined rail 45. In this state, since push plate 48 slides on the side wall of glue box 441, push plate 48 can still maintain the pushing force state when glue box 441 gradually moves upward, so that the material collection mechanism 44 moves closer to the side wall of lamp housing 6 and completes the bonding. The starting point and ending point of glue application both fall on the top of material collection mechanism 44, realizing the reception of the first and last glue materials. The worker uses the locking structure to lock the angle of push rod 47 handle. The locking structure can be bolt or buckle, which is not specifically limited here.

[0046] When applying glue, the glue applicator 23 first moves above the collection mechanism 44, and then the glue applicator 23 begins to discharge glue. If glue spraying occurs at this time, the sprayed glue can be collected by the collection mechanism 44. When the glue application of the glue applicator 23 is stable, the glue applicator 23 begins to move towards the glue tank 7. When the glue reaches the inside of the glue tank 7, the shape of the glue is still stable. After the glue applicator 23 has traveled a complete circle along the path of the glue tank 7, the back suction function is activated, and it returns to the top of the collection mechanism 44.

[0047] This setup eliminates the need to use the applicator head 23 to move back and forth to spread the accumulated adhesive. Then, the operator can reverse the push rod 47 to drive the material collection mechanism 44 down along the inclined rail 45 to reset and detach it from the side wall of the lamp housing 6, making it easier for the vehicle lamp to be assembled later.

[0048] Specifically, during the glue preparation stage, the electric slide rail 31 drives the slide table 33, lamp housing 6 and receiving assembly 4 to move together to the glue application station. The operator pushes the handle of the push rod 47, and pushes the material collection mechanism 44 along the inclined rail 45 with the slide seat 46 via the push plate 48. Since the push plate 48 has a sliding function, it can compensate for the change in height of the material collection mechanism 44, so that the side of the material collection mechanism 44 is tightly attached to the side wall of the lamp housing 6. Then, the handle of the push rod 47 is locked to keep it in the attached state, and the beginning and end of the glue application are transferred from the inside of the glue tank 7 to the top surface of the material collection mechanism 44.

[0049] During the formal glue application, the glue applicator 23 first starts dispensing glue above the collection mechanism 44. The unstable glue splashes in the initial stage are all collected by the collection mechanism 44 to prevent unstable glue from entering the glue tank 7 and disrupting the consistency of the glue form. After the glue dispensing stabilizes, the glue applicator 23 smoothly transitions into the glue tank 7 and travels along the path of the glue tank 7 to apply glue, ensuring that the glue layer in the glue tank 7 is continuous and uniform. When the glue travels around to the junction of the beginning and end, the glue applicator 23 starts to suck up and moves back to the top of the collection mechanism 44 to stop dispensing glue, collecting the remaining glue in the end stage outside the glue tank 7, preventing the glue from piling up in the glue tank 7. The entire glue application process does not require the glue applicator 23 to scrape the glue back and forth, avoiding the problems of glue scraping by the nozzle, glue overflow at the groove opening, and glue residue sticking to the glue applicator 23 and drying, thus improving the stability of the glue form.

[0050] After the adhesive is applied, the staff unlocks the push rod 47 and moves the push rod 47 to move the material collection mechanism 44 down along the inclined rail 45 to reset and detach from the lamp housing 6, so that the lamp housing 6 can be transferred to the next assembly process.

[0051] In Example 3, although the basic material collection mechanism 44 can receive the first and last pieces of adhesive, the adhesive residue on the surface will gradually dry and harden, which will affect the next use. Moreover, when the material collection mechanism 44 is separated from the workpiece, the adhesive residue is easily pulled apart. Under this condition, there is still a risk of adhesive overflow.

[0052] To address this issue, the internal structure of the material collection mechanism 44 was further optimized and improved.

[0053] See Figures 3-7The material collection mechanism 44 includes a glue box 441 and a top box 442 disposed on the top of the glue box 441. The bottom of the top box 442 is connected to an insertion tube 447. The outer wall size of the insertion tube 447 is adapted to the inner wall size of the glue box 441. The insertion tube 447 is inserted into the inside of the glue box 441, so that the top box 442 can slide vertically relative to the glue box 441. A telescopic cylinder 446 is installed on one side of the glue box 441. The piston rod end of the telescopic cylinder 446 is connected to the side wall of the top box 442. The telescopic cylinder 446 is used to drive the top box 442 to rise and fall. The top of the top box 442 is provided with a glue drop port 443. The glue drop port 443 is connected to the internal cavity of the top box 442. The glue can fall into the top box 442 through the glue drop port 443 and flow into the inside of the glue box 441 through the insertion tube 447.

[0054] Specifically, the material collection mechanism 44 adopts a structure of upper and lower split glue box 441 and top box 442. The top box 442 is slidably connected to the glue box 441 through the insertion tube 447 and is driven by the telescopic cylinder 446 to achieve lifting action. During the glue application process, the unstable glue at the beginning and end enters the inner cavity of the top box 442 through the glue drop port 443 at the top of the top box 442, and then flows into the glue box 441 below through the insertion tube 447 for centralized storage, thereby realizing the collection of waste glue. At the same time, the lifting of the top box 442 can realize the use of lamp housings 6 at different heights.

[0055] See Figures 3-7 A partition 444 is installed on one side of the inclined rail 45. The top of the partition 444 is inclined and fits against one side of the glue groove 7. The top of the partition 444 is at the same height as the glue groove 7. The top of the partition 444 is provided with an inclined surface, and a groove is opened at the top of the inclined surface. A rubber pad 4401 is provided on the side of the top box 442 near the lamp housing 6. The partition 444 is embedded in the middle of the rubber pad 4401. When the top box 442 is close to the lamp housing 6, the rubber pad 4401 fills the gap between the lamp housing 6 and the top box 442. During the process of sliding the top box 442 to the lamp housing 6, the rubber pad 4401 on the side of the top box 442 will first contact the side wall of the lamp housing 6, filling the assembly gap between the top box 442 and the lamp housing 6, ensuring the fit and sealing, and preventing the glue from overflowing from the gap. At the same time, the top edge of the partition plate 444 is lower than the side wall of the glue groove 7, forming a transition surface between the glue outlet 443 and the glue groove 7, ensuring that the glue applicator 23 moves smoothly and continuously from the glue outlet 443 to the glue groove 7, and avoiding any gaps in the glue form.

[0056] See Figures 3-7A scraper 445 is hinged to the top of the glue outlet 443 by a torsion spring. When the glue box 441 and the top box 442 are away from the lamp housing 6, the scraper 445 scrapes off the excess material by swinging in the opposite direction to one side of the glue trough 7 and scraping. Spring rods 448 are installed on the top of the top box 442 and on both sides of the glue outlet 443. The top of the scraper 445 is symmetrically provided with insertion holes 449. The two spring rods 448 are correspondingly provided with the two insertion holes 449. The top of the outer wall of the spring rod 448 is provided with an inclined part, and the bottom of the outer wall of the spring rod 448 is provided with a groove hook. The groove hook is hung inside the corresponding insertion hole 449.

[0057] See Figure 8 and Figure 9 In the initial state, the scraper 445 is hung by the spring rod 448 and the insertion hole 449. That is, the spring rod 448 restricts the scraper 445 below it. At this time, the torsion spring is in a compressed state, and the scraper 445 is suspended above the glue outlet 443. When the glue applicator 23 starts to apply glue above the glue outlet 443, the scraper 445 is still in the initial state. When the glue applicator 23 finishes applying glue and returns to the position of the glue outlet 443, the glue applicator 23 squeezes the scraper 445. The scraper 445 swings downward, causing the insertion hole 449 to separate from the groove hook of the spring rod 448. The spring rod 448 retracts due to its own elastic force and releases the lock, allowing the scraper 445 to swing freely. The scraper 445 swings towards the lamp housing 6 under the influence of the torsion spring, so that the end of the scraper 445 is in close contact with the side wall of the glue groove 7 and the top surface of the partition 444.

[0058] See Figure 9 and Figure 10 Then the piston rod of the telescopic cylinder 446 retracts, the top box 442 moves downward, and the scraper 445 begins to swing due to the obstruction of the rubber groove 7. The scraper 445 is blocked by the top shape of the partition 444. Since the partition 444 is connected to the inclined rail 45, the partition 444 remains stationary.

[0059] See Figure 9 and Figure 10 When the scraper 445 is pulled down, the right end of the scraper 445 is pulled down, while the left end remains stationary due to the obstruction of the partition 444 and the glue groove 7, and the obstruction position forms a fulcrum.

[0060] See Figure 10 When the right end of scraper 445 is lower than the left end, scraper 445 continues to be pulled down by top box 442, causing part of the left end of scraper 445 to be scraped by the top of glue tank 7, causing the glue on the left end of scraper 445 to be scraped to the top of glue tank 7, and the glue dragged out of glue tank 7 is sorted out, reducing the situation of pulling glue and stringing when the material collection mechanism 44 is separated from the lamp housing 6.

[0061] See Figure 11After the top box 442 is moved into place, the operator pulls down the handle of the push rod 47. The push rod 47 uses the push plate 48 to pull the collection mechanism 44 back as a whole. That is, the collection mechanism 44 moves downward along the inclined angle of the inclined rail 45, which causes the scraper 445 to scrape on the inclined surface of the partition plate 444, so that the colloid on the scraper 445 is scraped off.

[0062] After the material collection mechanism 44 is separated from the lamp housing 6, the worker resets the scraper 445 by pressing the scraper 445 below the spring rod 448, then pushing the spring rod 448 out and reinserting it into the socket 449 to lock it in place, thus completing the relocking of the scraper 445.

[0063] Furthermore, two bearing seats 41 are symmetrically installed on the top of the conveying assembly 3, and the platform 42 rotates between the two bearing seats 41. Two top blocks 43 are provided on the top of the conveying assembly 3. The two top blocks 43 are inserted on both sides of the platform 42 to provide auxiliary support for the top blocks 43. If the top box 442 is to be fitted to the side wall of the glue groove 7 of other shaped lamp housing 6, the platform 42 uses the bearing seats 41 and the rotating shaft to adjust the angle. The two top blocks 43 provide auxiliary support for the platform 42 to maintain the angle of the platform 42. In addition, the size of the two top blocks 43 can be adapted and replaced as needed.

[0064] Specifically, before applying glue to the lamp housing 6, the scraper 445 is in its initial state, that is, it is locked by the engagement of the slot hook of the spring rod 448 with the insertion hole 449. When the glue application head 23 applies glue, the unstable glue at the beginning and end falls into the inner cavity of the top box 442 through the glue drop port 443, and then flows into the glue box 441 below through the insertion tube 447 for centralized storage, thereby collecting waste glue and avoiding glue residue and drying everywhere. At the same time, the lifting adjustment of the top box 442 can adapt to lamp housing workpieces of different heights.

[0065] When the glue application is completed and the glue application head 23 falls back above the glue outlet 443, the glue application head 23 presses down on the scraper 445 to trigger unlocking. The spring rod 448 disengages from the insertion hole 449, and the scraper 445 swings towards the lamp housing 6 under the action of the torsion spring. The end of the scraper 445 is in close contact with the side wall of the glue groove 7. Then, the telescopic cylinder 446 drives the top box 442 to descend. As the scraper 445 moves down with the top box 442, it swings with the edge of the glue groove 7 as the fulcrum, scraping off a small amount of glue adhering to the end of the scraper 445 to the top of the glue groove 7, reducing the pulling of glue and stringing when the material collection mechanism 44 is separated from the lamp housing 6.

[0066] The scraper 445 is driven by the top box 442 to continue moving downward. The left end of the scraper 445 without adhesive slides on the side wall of the glue tank 7 and the lamp housing 6, causing the scraper 445 to slide to the inclined surface of the partition plate 444. When the entire material collection mechanism 44 is tilted and moved downward along the inclined rail 45 to reset, the adhesive at the bottom of the scraper 445 slides relative to the inclined surface of the partition plate 444, further scraping off the residual adhesive on the surface. The adhesive accumulates in the tank or enters the glue drop port 443 and is collected, reducing residual adhesive residue, avoiding the residual adhesive from drying and hardening and affecting subsequent use, and reducing the risk of adhesive overflow.

[0067] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
