Description

Technical Field

[0001] This invention relates to the field of adhesive coating equipment technology, and more particularly to a fully automatic adhesive coating equipment. Background Technology

[0002] Currently, in industrial production, the application of adhesive to rivet nuts for M3-M8 specification workpieces is mostly done using semi-automatic or manual methods, which have many drawbacks: manual application is inefficient, has poor application accuracy, uneven adhesive layer thickness, and is prone to overflow and breakage, resulting in poor product consistency and a high defect rate; semi-automatic application equipment requires manual assistance in feeding, material handling, and post-curing treatment, with many manual intervention steps, making it impossible to achieve integrated operation and difficult to improve production efficiency.

[0003] Meanwhile, existing adhesive coating equipment and curing equipment are mostly set up independently. After the adhesive is applied, the workpiece needs to be manually transferred to the curing equipment. During the transfer process, the adhesive layer is prone to flow and contamination, which affects the quality of the finished product. In addition, the transfer process increases labor costs and production cycle.

[0004] In addition, existing gluing equipment adapted to M3-M8 workpiece specifications is complex to switch between different workpiece specifications, requiring frequent adjustments to the equipment structure, making it impossible to quickly achieve mass production of multiple workpiece specifications, and its adaptability is poor. Moreover, existing gluing mechanisms are mostly linear conveying gluing, which has limited gluing efficiency and insufficient workpiece positioning stability. Especially for small workpieces such as screws, positioning misalignment is prone to occur, resulting in unqualified gluing. At the same time, most existing equipment can only adapt to workpieces of a single material, and cannot take into account the universal processing of stainless steel and carbon steel materials, which limits its applicability and makes it difficult to meet the needs of large-scale production.

[0005] In view of the shortcomings of the existing technology, there is an urgent need for a fully automatic glue application equipment that can solve the above technical problems. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] The following is in conjunction with the appendix Figure 1-13 The technical solutions provided by the various embodiments of the present invention are described in detail below.

[0026] This invention provides a fully automatic glue coating equipment, including a frame 1, a fully automatic feeding mechanism 2, a precision glue coating system 4, a workpiece gripping mechanism 5, an automatic conveyor line 6, and an oven line 7. The fully automatic feeding mechanism 2 is located beside the frame 1 and includes an automatic elevator 21, an automatic sorting component 22, and a workpiece adjustment mechanism 3. The automatic sorting component is located at the discharge end of the automatic elevator 21, and the workpiece adjustment mechanism 3 is located beside the automatic sorting component 22. The precision glue coating system includes a treatment agent application component 40, a glue application component 41, and a rotary glue coating component 4, all located on the top of the frame 1. 2. The treatment agent application component 40 and the glue application component 41 are arranged around the rotary glue application component. The treatment agent application component 40 and the glue application component 41 have the same structure and are used to apply the treatment agent and glue to the workpiece, respectively. The automatic conveyor line 6 is located on the side of the frame 1, the oven line 7 is located on top of the automatic conveyor line 6, and the workpiece gripping mechanism 5 is mounted between the automatic conveyor line 6 and the frame 1. The frame 1 is also equipped with a PLC control system 8. The PLC control system 8 is electrically connected to the fully automatic feeding mechanism 2, the precision glue application system 4 and the oven line 7, respectively, to realize the fully automated control of the process.

[0027] When the equipment is running, the fully automatic feeding mechanism 2 first completes the automatic lifting, sorting and posture correction of the messy workpieces to ensure that the workpieces have uniform posture and accurate position; then the workpiece gripping mechanism 5 accurately transfers the corrected workpieces to the precision gluing system 4 station. The coating agent application component 40, the adhesive application component 41, and the rotary adhesive application component 42 work together to complete a high-precision and high-efficiency adhesive application operation. The coated workpiece is conveyed to the oven line 7 via the automatic conveyor line 6, and undergoes preheating, curing, and cooling processes to complete the adhesive layer curing and molding. The entire process is automated and requires no manual intervention.

[0028] PLC Control System 8: It adopts touch screen operation, has built-in gluing programs for various M3-M8 specification workpieces and curing programs for different types of adhesives, supports program storage, recall and modification. Operators can set gluing parameters, curing parameters and conveying speed through the touch screen, and monitor the operating status of each mechanism of the equipment in real time. When the equipment malfunctions (such as insufficient adhesive, abnormal pressure, etc.), it can automatically alarm and stop the machine for timely handling.

[0029] It should be noted that before applying glue to the workpieces, the treatment agent is first applied to the four workpieces by the treatment agent application component 40 so that the glue can better adhere to the workpieces later. Then, the glue application component 41 is used to apply glue to the workpieces after the treatment agent has been applied.

[0030] Specifically, the automatic elevator 21 includes an elevator conveyor line 211, a conveyor frame 212, a hopper 213, and a discharge hopper 214. The elevator conveyor line 211 is located on the conveyor frame 212, the hopper 213 is located on the conveyor frame 212 and at the inlet end of the elevator conveyor line 211, and the discharge hopper 214 is located on the conveyor frame 212 and at the outlet end of the elevator conveyor line 211.

[0031] The automatic lifting machine 21 serves as a workpiece raw material conveying unit, while the hopper 213 is used to centrally store M3-M8 specification rivet nut workpieces to be processed, enabling batch storage of workpieces. After the equipment starts, the lifting conveyor line 211 operates stably under the fixed support of the conveyor frame 212, continuously lifting and conveying the messy workpieces piled up in the hopper 213 upwards. Through mechanical conveying, the workpieces are orderly transported to the discharge hopper 214. The discharge hopper 214 serves as a storage buffer and limiter for discharge, continuously and stably supplying workpieces to the downstream automatic sorting component 22, realizing automated continuous workpiece feeding and replacing the traditional manual feeding mode.

[0032] Specifically, the automatic sorting component 22 includes a vibrating base 221 with vibration function, a receiving bin 222, a track plate 223, a swing motor 224, and four positioning conveying tracks 225. The vibrating base 221 is located on the top of the frame 1. The receiving bin 222 is located on the frame 1, beside the vibrating base 221, and connected to the discharge bin 214. The track plate 223 is horizontally arranged between the base and the receiving bin 222. The four positioning conveying tracks 225 are evenly spaced on the track plate 223. The swing motor 224 is located on the receiving bin 222. The receiving bin 222 is provided with four rotating shafts 226. One end of each rotating shaft 226 is provided with a first rotating plate 227. The main shaft of the swing motor 224 is provided with a second rotating plate 228. A hinge plate 229 is provided between the second rotating plate 228 and the four first rotating plates 227. The other end of each rotating shaft 226 is provided with a swing brush plate 2290. The swing brush plate 2290 is located above the positioning conveying track 225. Each positioning conveying track 225 is located at the bottom of the discharge bin 214 and is provided with two receiving plates 2291 with an inward octagonal structure.

[0033] The receiving bin 222 of the discharge bin 214 receives the workpieces conveyed by the elevator. The workpieces fall into the positioning conveying track 225 of the track plate 223. The vibrating base 221 vibrates, causing the workpieces to vibrate on the four equally spaced positioning conveying tracks 225, so that the four groups of workpieces are synchronously diverted and conveyed forward.

[0034] When the equipment is running, the swing motor 224 drives the second rotating plate 228 on the main shaft to rotate, which in turn drives the four first rotating plates 227 to rotate synchronously through the hinge plate 229, thereby driving the four rotating shafts 226 and the swing brush plates 2290 at the ends to swing synchronously. The swing brush plates 2290 swing regularly above the positioning conveying track 225 to sort and organize the messy workpieces in the track, correcting the tilted, inverted, and misaligned workpieces to a uniform posture. At this time, the workpiece is in the state that the tip is inside the positioning conveying track 225 and the flat end is at the top of the positioning conveying track 225. Excess workpieces are returned to the material bin 213 through the receiving bin 222 for reloading.

[0035] Meanwhile, the receiving plate 2291 with an inner eight-shaped structure at the bottom of the positioning conveyor track 225 can limit and support the workpiece to prevent it from falling off or shifting, and finally transport the workpieces with uniform posture and regular arrangement to the next station in an orderly manner.

[0036] The fully automated self-sorting eliminates the need for manual sorting, completely solving the problems of low efficiency and large errors associated with manual sorting.

[0037] Specifically, the workpiece adjustment mechanism 3 includes a support 30, a drive motor 31, an adjustment moving plate 32, a first connecting plate 33, and a second connecting plate 34. The support 30 is vertically mounted on the top of the frame 1, and the drive motor 31 is located on the top of the support 30. Two vertically mounted slide rails 35 are provided on the side wall of the support 30. The adjustment moving plate 32 is provided with four slide blocks 36 arranged symmetrically in pairs. The four slide blocks 36 are slidably connected to the two slide rails 35 respectively. One end of the first connecting plate 33 is connected to the main shaft of the drive motor 31, and the two ends of the second connecting plate 34 are respectively hinged to the other end of the first connecting plate 33 and the adjustment moving plate 32.

[0038] Specifically, the adjusting movable plate 32 is provided with two symmetrically arranged flip shafts 37, each of which is horizontally rotatably connected to the adjusting movable plate 32. The adjusting movable plate 32 is provided with an L-shaped groove 321 for the flip shafts 37 to rotate. The two flip shafts 37 are respectively provided with horizontally arranged flip plates 371. One of the flip plates 371 is provided with a feeding clamping cylinder 38, which is provided with four feeding clamping ends 381. The other flip plate 371 is provided with a discharging clamping cylinder 39, which is provided with four discharging clamping ends 391.

[0039] The drive motor 31 serves as the power source. Through the crank-connecting rod transmission structure composed of the first connecting plate 33 and the second connecting plate 34, it drives the adjustment moving plate 32 to make precise lifting and lowering displacement along the vertical slide rails 35 on both sides of the support 30 via the slide block 36, thereby achieving precise height adjustment. The adjustment moving plate 32 is equipped with two sets of rotatable flip shafts 37 and L-shaped grooves 321, which can drive the two sets of flip plates 371 to complete the angle flipping adjustment, changing the loading clamping cylinder 38 and the unloading clamping cylinder 39 from the vertical state to the horizontal state and then back to the vertical state, adapting to the workpiece posture correction requirements.

[0040] During the loading process, the up-and-down movement of the adjusting moving plate 32 causes the loading clamping cylinder 38 and the unloading clamping cylinder 39 to rotate. First, the loading clamping cylinder 38 rotates to a vertical position, and then the four loading clamping ends 381 of the loading clamping cylinder 38 clamp the large flat ends of the workpieces on the four positioning conveying tracks 225. Subsequently, the drive motor 31 operates, causing the tilting shaft 37 to rotate within the L-shaped groove 321, which in turn causes the loading clamping cylinder 38 to rotate from a vertical position to a horizontal position. At the same time, the unloading clamping cylinder 39 also rotates from a vertical position to a horizontal position. Then, the four unloading clamping ends 391 on the unloading clamping cylinder 39 clamp the tip of the workpiece. Then, the drive motor 31 works again to drive the flipping shaft 37 to rotate in the L-shaped groove 321, rotating the horizontal unloading clamping cylinder 39 to a vertical position, so that the four unloading clamping ends 391 are located on the top of the rotating disk 423. The four unloading clamping ends 391 place the workpiece on the strong magnet 433 and insert the large flat end into the tip rod, completing the adjustment of the workpiece position (at this time, the large flat end of the workpiece is attracted by the strong magnet 433 so that the tip is in a vertical position, so that glue can be applied to the large flat end and the tip later. The large flat end is provided with an insertion hole).

[0041] Specifically, the adhesive application assembly 41 includes an automatic adhesive applicator 411, a mounting base 412, a lead screw slide assembly 413, and an adhesive application mounting seat 414. The mounting base 412 is disposed on the top of the frame 1, the lead screw slide assembly 413 is disposed on the mounting base 412, and the adhesive application mounting seat 414 is located at one end of the lead screw slide assembly 413. Four automatic adhesive applicators 411 are provided, and the four automatic adhesive applicators 411 are equally spaced on the adhesive application mounting seat 414. Each automatic adhesive applicator 411 is equipped with a metering pump 415. The metering pump 415 is a CB-BNS10 model.

[0042] The lead screw slide assembly 413 serves as a precise displacement adjustment mechanism, which can drive the glue application mounting base 414 to achieve precise horizontal displacement adjustment, accurately adapting to the glue application position requirements of workpieces of different specifications. The adhesive application mounting base 414 is symmetrically equipped with two sets of automatic adhesive application nozzles 411 to form a dual adhesive application station. Each automatic adhesive application nozzle 411 is independently equipped with a metering pump 415, which can accurately control the amount of adhesive, the speed of adhesive application and the duration of adhesive application. When the equipment is running, the horizontal position of the glue applicator is precisely adjusted by the screw slide group 413. Combined with the quantitative glue control function of the metering pump 415, the glue is applied to the rivet nut workpieces that have been positioned on the workstation in a fixed point and in a fixed quantity. The glue application trajectory, glue layer thickness and glue output can be precisely adjusted according to the glue application requirements of different specifications of workpieces from M3 to M8.

[0043] Four automatic glue-applying nozzles 411 can apply glue to four workpieces simultaneously, effectively improving glue-applying efficiency and significantly increasing production capacity compared to single-nozzle glue-applying equipment; the independent metering pump 415 quantitatively controls glue, completely solving the problems of glue overflow, glue breakage, and uneven glue layer thickness in traditional manual and semi-automatic glue-applying processes, ensuring that the glue layer on each workpiece is uniform and consistent, and significantly improving the product qualification rate. The 413 lead screw slide assembly offers precise displacement adjustment, enabling quick adaptation to the glue application position adjustment of workpieces ranging from M3 to M8. It facilitates convenient specification switching without requiring complex structural modifications, resulting in enhanced equipment adaptability. It can accurately match the glue application process requirements of workpieces made of different materials, such as stainless steel and carbon steel, achieving universal processing for multiple materials.

[0044] Specifically, the rotary adhesive applicator 42 includes a base 421, a divider 422, a rotating disk 423, a motor base 424, a rotating motor 425, a rotating pulley 426, and a protective cover 427. The base 421 is located on the frame 1, the divider 422 is located on the base 421, the rotating disk 423 is horizontally arranged on the rotating end of the divider 422, the motor base 424 is located beside the base 421, the rotating motor 425 is located on the motor base 424, the rotating pulley 426 is located on the main shaft of the rotating motor 425, the rotating disk 423 is provided with a plurality of equally spaced rotating stations 43, and the protective cover 427 covers the outside of the motor base 424; the plurality of rotating stations 43 is thirty-two rotating stations 43. Each small workstation has a diameter of 20mm and contains a built-in circular strong magnet 433 (model N35, diameter 15mm, thickness 10mm). The surface of the strong magnet 433 is flush with the workstation table surface, and the adsorption force is ≥50N, which can stably adsorb M3-M8 screws made of carbon steel. The rotation speed can be steplessly adjusted within the range of 50-200 rpm and is independently controlled by PLC to ensure uniform glue application.

[0045] Specifically, each of the rotating stations 43 includes a rotating shaft 431, a rotating pulley 432, and a strong magnet 433. The rotating shaft 431 is rotatably connected to the rotating disk 423, and the rotating pulley 432 is located on the rotating shaft 431. The strong magnet 433 is located on the rotating disk. A push rod 434 is provided inside the rotating shaft 431. A top rod 435 is provided at the bottom of the push rod 434. The top rod 435 and the push rod 434 are in sliding fit. A spring 436 is provided between the push rod 434 and the top rod 435. A threaded section 437 is provided at the bottom of the push rod 434. An adjusting nut 438 is provided on the threaded section 437. A connecting belt is sleeved between the rotating pulley 426 and several rotating pulleys 432.

[0046] For stainless steel workpieces, align the insertion hole at the flat end of the workpiece with the top rod 435 to complete the workpiece's positioning and fixation, so that the workpiece is placed vertically on the rotating disk 423, providing a stable working condition for subsequent glue application.

[0047] During the workpiece positioning process, the extension length of the push rod 434 and the center rod 435 on the rotating disk 423 can be adjusted by rotating the adjusting nut 438 to adapt to the positioning requirements of workpieces of different specifications.

[0048] When the insertion hole at the large flat end of the workpiece is fitted with the center rod 435, it will push the center rod 435 to slide along the axial direction of the top rod 434 and compress the spring 436. After the workpiece is inserted into place, the spring 436 will elastically return to its original position, driving the center rod 435 to fit tightly into the insertion joint, thereby reliably locking the position of the workpiece and achieving precise positioning and fixation.

[0049] The rotating motor 425 on the motor base 424 provides power, and through the rotating pulley 426 and the belt, the rotating pulleys 432 and rotating shafts 431 of all stations on the rotating disk 423 rotate synchronously. Multiple rotating stations 43 are evenly spaced in a ring on the rotating disk 423. Each station magnetically holds the carbon steel workpiece in place via a strong magnet 433 at the top of the rotating shaft 431, preventing the workpiece from shifting or falling off during the adhesive application process. During operation, the rotating disk 423 rotates intermittently, sequentially conveying the workpieces from each station to the working area of ​​the adhesive application assembly 41. Simultaneously, each station itself can rotate the workpiece, working in conjunction with the adhesive nozzle to complete omnidirectional adhesive application without blind spots, achieving synchronous cyclical operation of multiple stations for loading, applying adhesive, and unloading.

[0050] The 433 strong magnet at the workstation provides a magnetic positioning method that is suitable for fixing small rivet nuts and other workpieces. The positioning is stable and without deviation, completely solving the problem of glue defects caused by unstable workpiece positioning in traditional equipment. The workpiece rotates synchronously with the workstation, achieving 360° all-round uniform glue application with no blind spots, further improving glue application accuracy and product consistency; the 422 indexer ensures precise indexing, minimizing workstation switching errors and enhancing equipment operation stability and repeatability.

[0051] Specifically, the workpiece gripping mechanism 5 includes a first support rod 50, a second support rod 51, a gripping moving slide assembly 52, a mounting plate 53, a lifting motor 54, a first lifting rod 55, a second lifting rod 56, a placement frame 57, a lifting slide 58, a lifting slide rail 59, and a gripping clamping cylinder 590. The first support rod 50 is mounted on the automatic conveyor line 6, the second support rod 51 is mounted on the frame 1, the gripping moving slide assembly 52 is horizontally mounted on the first support rod 50 and the second support rod 51, and the mounting plate 53 is vertically mounted on the gripping moving slide assembly 590. On the moving end of the unit 52, the lifting motor 54 is located on the mounting plate 53, the lifting slide rail 59 is vertically mounted on the mounting plate 53, the lifting slide block 58 is vertically connected to the lifting slide rail 59, the first lifting rod 55 is located on the main shaft of the lifting motor 54, the two ends of the second lifting rod 56 are hinged to the first lifting rod 55 and the lifting slide block 58, the placement frame 57 is located on the side wall of the lifting slide block 58, and the gripping and clamping cylinder 590 is mounted on the placement frame 57. The gripping and clamping cylinder 590 is provided with four gripping and clamping ends 591.

[0052] The grasping and moving slide group 52 achieves precise horizontal displacement, driving the overall grasping structure to move back and forth between the feeding station and the gluing and conveying station; During operation, the lifting motor 54 drives the lifting slide 58 to move up and down on the lifting slide rail 59 through the articulated transmission structure composed of the first lifting rod 55 and the second lifting rod 56. This causes the gripping and clamping cylinder 590 to move up and down. The gripping and clamping cylinder 590 grips the four workpieces on the rotating disk 423 through its four gripping and clamping ends 591. Then, the gripping and moving slide group 52 moves the gripped workpieces onto the automatic conveyor belt for orderly arrangement, so that the adhesive can be cured subsequently.

[0053] When the equipment is running, the mechanism precisely aligns the workpiece through horizontal movement and vertical lifting, and completes the gripping and transfer of the corrected workpiece and the unloading and conveying of the workpiece after gluing, realizing the automated and precise transfer of workpieces between each process.

[0054] It should be noted that after production is completed, the operator should stop the equipment via the touch screen, first stop the glue supply, clean the glue nozzle and glue supply system of any residual glue, turn off the heating function of oven line 7, and after the oven temperature drops to room temperature, turn off the power and gas supply of the equipment, and make a record of the equipment cleaning and maintenance for the next use.

[0055] Specifically, the oven line 7 adopts a segmented heating design, and the oven line 7 includes a preheating section, a curing section and a cooling section.

[0056] The workpiece is first preheated in the preheating section (temperature 30-50℃), and then enters the curing section for curing. The curing temperature and time are set according to the type of adhesive (acrylic adhesive 50-80℃, 5-15 minutes; silicone adhesive 80-150℃, 8-20 minutes). During the curing process, temperature and humidity sensors monitor the environmental parameters inside the oven in real time, and the PLC control system automatically adjusts the temperature and humidity to ensure the curing effect. After curing, the workpiece enters the cooling section to cool to room temperature (25±5℃).

[0057] The temperature inside oven line 7 can be steplessly adjusted within the range of 50-150℃, with a temperature control accuracy of ±2℃. The heating is uniform, and the curing temperature and time can be preset according to the curing requirements of different types of adhesives. After curing, the product is cooled to room temperature in the cooling section and directly output as a finished product. Oven line 7 is equipped with a temperature sensor to monitor the temperature parameters inside the oven in real time.

[0058] It should be noted that the matching oven line 7 is 5000mm long, including a 1000mm preheating section, a 3000mm curing section, and a 1000mm cooling section. The heating element is made of stainless steel and has a power of 5kW. The temperature sensor is a PT100 model and the temperature control accuracy is ±2℃.

[0059] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
