Description

Technical Field

[0001] This invention belongs to the field of sealing strip processing, and in particular relates to a sealing strip stacking device. Background Technology

[0002] In the manufacturing process of sealing strips, in order to improve sealing performance and ease of installation, a thin strip is usually attached to the surface of the strip. The thin strip is attached to the three surfaces of the closed end and the two open ends of the strip, which serves to enhance sealing, wear resistance or decoration.

[0003] The bonding process of sealing strips mainly relies on manual operation or semi-automatic equipment. In manual operation, the operator first applies adhesive to the surface of the U-shaped strip, then manually cuts the strip to a predetermined length, and then applies it to the closed end and two open ends of the strip. Finally, it is pressed by a pressure roller. In the whole process, the processes of applying adhesive, bonding, and pressing are carried out separately, requiring multiple handling and positioning of the U-shaped strip. The operation steps are cumbersome and the production efficiency is low. Therefore, there is a need for a device that can automatically bond the U-shaped strip surface strip in one go with high production efficiency to solve the above-mentioned problems in the existing technology. Summary of the Invention

[0004] In view of this, the present invention aims to provide a sealing strip stacking device to solve the problems of low efficiency and unstable bonding quality of traditional sealing strip thin sheet bonding process.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

The pressing unit is used to press the thin strip onto the upper end of the U-shaped adhesive strip.

[0008] Furthermore, the feeding unit includes a sheet roll, guide shafts, a straight plate, an inclined plate, and a rotating motor. The sheet roll is rotatably mounted on the front side of the support plate. One side of the sheet roll is fixedly connected to the movable end of the rotating motor. The rotating motor is fixedly mounted on the rear side of the straight plate. The sheet roll stretched from the sheet roll is sequentially wound around the periphery of multiple guide shafts. The multiple guide shafts are rotatably mounted on the front side of the support plate. The straight plate is located between two guide shafts arranged in the same straight line. The straight plate has a straight groove. The periphery of the sheet roll is slidably mounted in the straight groove. An inclined plate is inclinedly mounted below the front side of the support plate. The inclined plate has an inclined groove. The end of the sheet roll is slidably mounted in the inclined groove.

[0009] Furthermore, the clamping unit includes a slider, a first cylinder, a second cylinder, a pressure plate, and an L-shaped plate. A groove is provided on the front side of the support plate, and the slider is slidably arranged in the groove. One end of the slider is fixedly connected to the movable end of the first cylinder. The first cylinder is fixedly installed on the support plate. An L-shaped plate is fixedly installed on the front side of the slider. A thin strip is slidably arranged on the upper end of the L-shaped plate. A second cylinder is fixedly installed on the front side of the L-shaped plate. A pressure plate is fixedly arranged on the movable end of the second cylinder. The pressure plate can approach the L-shaped plate and clamp the thin strip.

[0010] Furthermore, the transverse bonding assembly also includes a speed measuring device, which is installed on the front side of the support plate and located above the straight plate, with the identification end of the speed measuring device facing the thin strip inside the straight groove.

[0011] Furthermore, the pressing unit includes a third cylinder, a roller frame, and rollers. The third cylinder is fixedly installed on the front side of the support plate.

The cutting blade is located at the upper end of the inclined plate.

[0013] Furthermore, the lower end of the inclined plate is an arc-shaped end face, which can slide and fit against the upper surface of the U-shaped adhesive strip.

[0014] Compared with the prior art, the sealing strip stacking device of the present invention has the following advantages:

[0015] (1) The sealing strip stacking equipment of the present invention, through the setting of the transverse bonding component and two longitudinal bonding components, can complete the bonding of the closed end and two open ends of the U-shaped strip in one go, with high production efficiency. The continuous cooperation of the feeding unit, clamping unit, cutting unit and pressing unit automates the entire process of the thin strip from unwinding to pressing, reduces manual operation, and ensures stable bonding quality.

[0016] (2) The sealing strip stacking device of the present invention uses a speed measuring device to monitor the speed of the thin strip traveling in the straight groove in real time, so that the controller can accurately grasp the feeding speed of the thin strip. Through the real-time feedback of the speed signal, the pushing action of the clamping unit can be precisely matched with the actual traveling speed of the thin strip, ensuring consistent cutting length and accurate bonding position, reducing cutting error and bonding offset caused by feeding speed deviation, and improving bonding quality.

[0017] (3) The sealing strip stacking equipment of the present invention has an adhesive coating device that realizes the automated operation of adhesive coating on the surface of U-shaped adhesive strips, which improves the adhesive coating efficiency. The second and third-direction moving platform can drive the adhesive coating head to move flexibly in three-dimensional space to adapt to the adhesive coating needs of U-shaped adhesive strips of different sizes and shapes, thereby improving production efficiency.

[0018] (4) In the sealing strip stacking device of the present invention, two reinforcing ribs are always fixed on both sides of the glue application seat, which supports and reinforces the glue application seat, making it less likely to bend or deform during the movement of the glue application seat, thus ensuring the positional accuracy of the glue application head and the stability of the glue application.

[0019] (5) The sealing strip stacking device of the present invention uses the heating component to heat the heating wire in the heating box and the fan to force the hot air to circulate, so that the temperature inside the heating box is evenly distributed and the surface of the U-shaped strip after being coated with glue is evenly heated to avoid local overheating or insufficient heating. The fan setting speeds up the flow of hot air, so that the glue can reach the required temperature state in a short time.

[0020] (6) The sealing strip stacking device of the present invention provides a position reference for the zero point component identification platform. With the precise positioning of the photoelectric sensor, it ensures that the glue applicator only starts applying glue when the U-shaped glue strip reaches the accurate position, avoiding glue application position deviation or missed application, and improving glue application positioning accuracy. The glue receiving tube is set on one side of the identification platform, which can collect glue dripping or residual glue from the glue applicator.

[0021] (7) The sealing strip stacking device of the present invention uses an upper and lower conveying frame with a double-layer structure and lifting components at both ends to realize the cyclic turnover transportation of the support plate, so that the support plate can be used repeatedly without the need for manual handling of empty support plates from the end to the beginning, thereby improving the conveying efficiency.

[0022] (8) The sealing strip stacking device of the present invention provides continuous support for the conveyor belt below the conveyor belt, so that the conveyor belt remains flat in the section of the support plate and does not undergo concave deformation, and ensures that the upper surface of the conveyor belt always remains flat, thereby ensuring that the support plate runs smoothly during the conveying process.

[0023] (9) The sealing strip stacking device of the present invention has clamping parts respectively set on the conveyor frame body corresponding to the positions of the gluing device and the bonding device. When the support plate arrives at each process station, the support plate is clamped and fixed to prevent the U-shaped adhesive strip from shifting position due to external force or equipment vibration during the gluing, cutting and bonding process, thus ensuring the positional accuracy of each process.

When the thin strip 5 slides in the straight groove 61531, the recognition end of the speed sensor 617 collects the surface motion speed signal of the thin strip 5 in real time and feeds back the detected speed data to the controller. The controller then determines the speed based on the received speed data. The signal determines the real-time feeding status of the thin strip 5, providing a basis for the subsequent push timing and push length control of the clamping unit 614. The speed detector 617 monitors the real-time speed of the thin strip 5 traveling in the straight groove 61531, enabling the controller to accurately grasp the feeding speed of the thin strip 5. Through real-time feedback of the speed signal, the push action of the clamping unit 614 can be precisely matched with the actual traveling speed of the thin strip 5, ensuring consistent cutting length and accurate bonding position, reducing cutting errors and bonding offsets caused by feeding speed deviations, and improving bonding quality.

[0057] like Figure 7 As shown, the cutting unit 616 includes a fourth cylinder 6161 and a cutting blade 6162. The fourth cylinder 6161 is located on the front side of the support plate 612, and the cutting blade 6162 is fixedly mounted on the movable end of the fourth cylinder 6161. The cutting blade 6162 is located at the upper end of the inclined plate 6154. When the cutting unit 616 is working, the fourth cylinder 6161 is activated after the sheet belt 5 is released to a predetermined length. The fourth cylinder 6161 is existing technology, and its model is SC50x10. At 0S, its movable end extends and drives the cutting blade 6162, which is located at the upper end of the inclined plate 6154. The cutting blade 6162 moves downward under the drive of the fourth cylinder 6161, cutting the thin strip 5 at the upper position of the inclined plate 6154. After cutting, the fourth cylinder 6161 drives the cutting blade 6162 to reset, and the first three-way moving platform 611 continues to move, rolling and sticking the excess part of the U-shaped adhesive strip 3 to the U-shaped adhesive strip 3 through the roller 6133. The lower end of the inclined plate 6154 is an arc-shaped end face 61542, which can slide and stick to the upper surface of the U-shaped adhesive strip 3. The arc-shaped end face 61542 can smooth the adhesive on the U-shaped adhesive strip 3 during the process of pasting the thin strip 5, making it easier for the thin strip 5 to stick to the upper end of the U-shaped adhesive strip 3.

[0058] like Figure 8As shown, the glue application device 4 includes a glue application assembly 41 and a heating assembly 42. The glue application assembly 41 is installed inside the housing 1, and the heating assembly 42 is installed downstream of the glue application assembly 41. The glue application assembly 41 includes a second three-way moving platform 411, a glue application seat 412, a glue container 413, and a glue application head 414. The second three-way moving platform 411 is fixedly installed inside the housing 1. The glue application seat 412 is fixedly installed at the movable end of the second three-way moving platform 411. The glue container 413 is installed on the glue application seat 412 and is used to hold glue. The lower end of the glue container 413 is connected to the upper end of the glue application head 414. The lower end of the glue application head 414 faces the U-shaped glue strip 3. The glue application device 4 realizes the automated operation of applying glue to the surface of the U-shaped glue strip 3, improving the glue application efficiency. The second three-way moving platform 411 can drive the glue application head 414 to move flexibly in three-dimensional space to adapt to the glue application needs of U-shaped glue strips 3 of different sizes and shapes, and the glue application position is precise and controllable. The glue container 413 on the glue applicator 412 is directly connected to the glue applicator head 414, resulting in a short glue supply path and fast response, enabling continuous and stable glue application and avoiding glue interruptions or uneven flow. The heating component 42 is located downstream of the glue applicator 41, and heats and cures the glue immediately after application, effectively shortening the glue drying time and improving production efficiency. It also ensures the glue reaches a suitable tack before bonding, which is beneficial for subsequent bonding of thin sheets and strips. When the glue applicator 4 is working, the second three-way moving platform 411 fixed inside the housing 1 drives the glue applicator 412 to move in three-dimensional space according to the controller command, adjusting the glue container 413 and the glue applicator head 414 on the glue applicator 412 to the predetermined glue application position above the U-shaped adhesive strip 3. The glue contained in the glue container 413 is heated and cured by its own weight or external forces. Under pressure, the glue flows downward and enters the glue application head 414 from the top. The bottom of the glue application head 414 faces the surface of the U-shaped adhesive strip 3. The glue flows out from the bottom of the glue application head 414 and is applied to the surface of the U-shaped adhesive strip 3. After the glue is applied, the heating component 42 installed downstream of the glue application component 41 heats the glued U-shaped adhesive strip 3 to keep the glue in a molten state. The glue application device 4 realizes the automated operation of applying glue to the surface of the U-shaped adhesive strip 3, which improves the glue application efficiency. The second and third-axis moving platform 411 can drive the glue application head 414 to move flexibly in three-dimensional space, which improves production efficiency.

[0059] like Figure 9 As shown, a reinforcing rib 4121 is provided on each side of the glue applicator 412. The two reinforcing ribs 4121 are always fixed on both sides of the glue applicator 412, which supports and reinforces the glue applicator 412, making it less likely to bend or deform during movement, thus ensuring the positional accuracy and glue application stability of the glue applicator head 414.

[0060] like Figure 11 and Figure 12As shown, the heating assembly 42 includes a heating box 421, a heating wire 422, and a fan 423. The heating box 421 is located inside the housing 1 and downstream of the adhesive application assembly 41. The conveying device 2 passes through the heating box 421. The heating wire 422 is installed inside the heating box 421. An air outlet 4211 is provided at the upper end of the heating box 421, and a fan 423 is installed on the air outlet 4211. The heating wire 422 is existing technology, and its model is DTDRG. The fan 423 is existing technology, and its model is Panasonic FV-17CG1C. When the heating assembly 42 is working, the U-shaped adhesive strip 3 after adhesive application is transported into the heating box 421 by the conveying device 2. The heating wire 422 inside the heating box 421 is energized and heats up, raising the air temperature inside the heating box 421. The fan 423 blows air into the heating box 421 through the air outlet 4211 at the top of the heating box 421, accelerating the flow of hot air inside the heating box 421 and making the hot air evenly distributed in the inner cavity of the heating box 421. The high-temperature airflow continuously blows onto the surface of the U-shaped adhesive strip 3 passing through the heating box 421, heating the adhesive on the surface of the U-shaped adhesive strip 3 and keeping the adhesive in a suitable molten state. The heating component 42 heats the heating wire 422 in the heating box 421 and works with the fan 423 to force the circulation of hot air, so that the temperature inside the heating box 421 is evenly distributed, and the surface of the U-shaped adhesive strip 3 after being coated with adhesive is evenly heated, avoiding local overheating or underheating. The fan 423 accelerates the flow of hot air, so that the adhesive can reach the required temperature in a short time.

[0061] like Figure 10As shown, a zero-point assembly 43 is provided on the conveying device 2. The zero-point assembly 43 includes an identification platform 431 and a glue receiving tube 432. The identification platform 431 is fixedly installed on the conveying device 2, and the glue receiving tube 432 is installed on one side of the identification platform 431. A photoelectric sensor 44 is provided on the outside of the glue container 413. The identification end of the photoelectric sensor 44 faces the U-shaped glue strip 3. The photoelectric sensor 44 is existing technology, and its model is E3Z-T61. 2M, the distance between the recognition end of the photoelectric sensor 44 and the glue applicator 414 is equal to the distance between the recognition platform 431 and the glue receiving tube 432. When the zero-point component 43 is working, the U-shaped glue strip 3 on the conveying device 2 moves forward with the conveying device 2. The recognition platform 431, which is fixedly installed on the conveying device 2, identifies the zero point position and provides a reference position for subsequent glue application and bonding processes. The glue receiving tube 432 is set on one side of the recognition platform 431 and is used to collect glue dripping or remaining from the glue applicator 414 during non-working periods. The recognition end of the photoelectric sensor 44, which is set on the outside of the glue container 413, faces the surface of the U-shaped glue strip 3. The photoelectric sensor 44 emits... The photoelectric sensor 44 emits photoelectric signals and receives reflected signals to detect whether the U-shaped adhesive strip 3 has reached the predetermined glue application position. The photoelectric sensor 44 sends a position signal to the controller. The controller starts the second and third-axis moving platform 411 of the glue application assembly 41 to perform the glue application action based on the signal. The recognition platform 431 of the zero point assembly 43 provides a position reference. With the precise positioning of the photoelectric sensor 44, it ensures that the glue application head 414 starts applying glue only when the U-shaped adhesive strip 3 reaches the accurate position, avoiding glue application position deviation or missed application, and improving glue application positioning accuracy. The glue receiving tube 432 is set on one side of the recognition platform 431 and can collect glue dripping or residual glue from the glue application head 414.

[0062] like Figure 13 and Figure 14As shown, the conveying device 2 includes an upper conveyor frame 21, a lower conveyor frame 22, a lifting assembly 23, and a support plate 24. The upper conveyor frame 21 is installed inside the housing 1, and the lower conveyor frame 22 is located below the upper conveyor frame 21. A lifting assembly 23 is installed at each end of the upper conveyor frame 21. The lifting assembly 23 switches the support plate 24 between the upper conveyor frame 21 and the lower conveyor frame 22. The support plate 24 can support the U-shaped rubber strip 3. The upper conveyor frame 21 and the lower conveyor frame 22 have the same structure but opposite conveying directions. The conveyor frame 21 includes a conveyor frame body 211 and a first conveying section 212. The conveyor frame body 211 is fixedly installed inside the housing 1. Two first conveying sections 212 are provided on the conveyor frame body 211. Each first conveying section 212 includes a conveyor wheel 213, a conveyor belt 214, a shaft 215, and a dual-axis motor 216. The conveyor frame body 211 is provided with two parallel mounting slots 2111. Two conveyor wheels 213 are rotatably installed in each mounting slot 2111. The two conveyor wheels 213 are connected by a sleeve around their periphery. The conveyor belt 214 forms a synchronous transmission structure. The upper end of the conveyor belt 214 can adhere to the support plate 24 and drive the support plate 24 to move. A dual-axis motor 216 is installed on the conveyor frame body 211. The movable end of each dual-axis motor 216 is fixedly connected to a shaft 215. Each shaft 215 can be fixedly connected to one side of a conveyor wheel 213. The dual-axis motor 216 is a prior art technology. The model of the dual-axis motor 216 is 57CM13-SZ. When the conveyor device 2 is working, the dual-axis... The motor 216 starts, and its two movable ends drive two shafts 215 to rotate synchronously. Each shaft 215 drives a conveyor wheel 213 in the corresponding mounting slot 2111 to rotate. The conveyor wheel 213 forms synchronous transmission through the conveyor belt 214 sleeved around it. The upper end of the conveyor belt 214 is in contact with the bottom surface of the support plate 24. Under the action of friction, the support plate 24 moves forward along the upper conveyor frame 21, so that the support plate 24 passes through the glue application device 4 and the bonding device 6 in sequence to complete each process. When the support plate 24 moves to the end of the upper conveyor frame 21, the lifting component 23 located at the end of the upper conveyor frame 21 switches the support plate 24 from the upper conveyor frame 21 to the lower conveyor frame 22. The structure of the lower conveyor frame 22 is the same as that of the upper conveyor frame 21, but the conveying direction is opposite. The support plate 24 is conveyed back to the starting end in the opposite direction on the lower conveyor frame 22.When the support plate 24 reaches the end of the lower conveyor frame 22, the lifting component 23 located at the starting end of the upper conveyor frame 21 switches the support plate 24 from the lower conveyor frame 22 back to the upper conveyor frame 21, realizing the cyclic turnover of the support plate 24 and continuously conveying the U-shaped rubber strips 3 to each process station. The conveying device 2, through the upper and lower double-layer structure of the upper conveyor frame 21 and the lower conveyor frame 22, combined with the lifting components 23 at both ends, realizes the cyclic turnover of the support plate 24, enabling the support plate 24 to be used repeatedly without the need for manual handling of the empty support plate 24 from the end to the starting end, thus improving the conveying efficiency. The upper conveyor frame 21 and the lower conveyor frame 22 convey in opposite directions, so that after the support plate 24 completes the processing and conveying of the U-shaped rubber strips 3 on the upper layer, it returns empty from the lower layer. The structure is compact and occupies a small area.

[0063] like Figure 15 As shown, a liner 217 is provided between the two conveyor wheels 213. The liner 217 is fixedly installed in the mounting groove 211. The liner 217 can support the conveyor belt 214. The liner 217 is fixedly installed in the mounting groove 2111 and located between the two conveyor wheels 213. The upper surface of the liner 217 is in contact with the upper inner side of the conveyor belt 214. When the support plate 24 is placed on the upper end of the conveyor belt 214, the weight of the support plate 24 and the U-shaped rubber strip 3 it carries is transferred to the liner 217 through the conveyor belt 214. The liner 217 continuously supports the conveyor belt 214 from below, so that the section of the conveyor belt 214 supporting the support plate 24 remains flat and does not deform downwards. This ensures that the upper surface of the conveyor belt 214 always remains flat, thereby ensuring that the support plate 24 runs smoothly during the conveying process.

[0064] like Figure 14As shown, a clamping part 25 is sequentially arranged on the conveyor frame body 211 at the positions corresponding to the glue application device 4 and the bonding device 6. The clamping part 25 includes a clamping plate 251, a slide bar 252, a clamping cylinder 253, a first metal plate 254, and a second metal plate 255. The clamping cylinder 253 is existing technology, and the model of the clamping cylinder 253 is SCD200X500S. The first metal plate 254 is fixedly installed on both sides of the conveyor frame body 211, and a second metal plate 255 is arranged on the upper end of each first metal plate 254. Two sliding rods 252 slide through the metal plate 255. The other ends of the two sliding rods 252 are fixedly connected to a clamping plate 251. One side of the clamping plate 251 is fixedly connected to the movable end of the clamping cylinder 253. The clamping cylinder 253 is fixedly installed on the upper end of the first metal plate 254. The two clamping plates 251 can approach each other and clamp on both sides of the support plate 24. When the conveying device 2 is running, the support plate 24 carries the U-shaped adhesive strip 3 and moves along the upper conveyor frame 21. When the support plate 24 reaches the corresponding adhesive applicator 4 and the adhesive strip 3 on the conveyor frame body 211, the adhesive strip 3 is applied to the support plate 254. When the clamping part 25 at position 6 of the assembly device is engaged, the controller issues a clamping command, the clamping cylinder 253 is activated, its movable end extends, and pushes the clamping plate 251 toward the support plate 24. The two sliding rods 252 pass through the second metal plate 255 and slide together with the clamping plate 251. The two clamping parts 25 act simultaneously from both sides of the conveyor frame body 211, and the clamping plates 251 on both sides approach each other and clamp the support plate 24 on both sides, clamping and fixing the support plate 24. When the gluing or bonding process is completed, the controller issues a release command. The clamping cylinder 253 drives the clamping plate 251 to move in the opposite direction. The two clamping plates 251 move away from each other and release the support plate 24. The support plate 24 returns to its free state and continues to move along the conveying direction to the next station. The clamping part 25 is set on the conveyor frame body 211 at the positions corresponding to the glue application device 4 and the bonding device 6. When the support plate 24 arrives at each process station, it clamps and fixes the support plate 24 to prevent the U-shaped adhesive strip 3 from shifting position due to equipment vibration during glue application, cutting and bonding, thus ensuring the positional accuracy of each process.

[0065] like Figure 14As shown, the lifting assembly 23 includes a lifting frame 231, a second conveying section 232, and lifting cylinders 233. A lifting frame 231 is installed at the beginning and end of the conveying frame body 211. Two second conveying sections 232 are installed on the upper end of each lifting frame 231. The second conveying sections 232 have the same structure as the first conveying section 212. The lower end of each lifting frame 231 is connected to the movable ends of two lifting cylinders 233. The two lifting cylinders 233 are vertically installed inside the housing 1. The lifting cylinders 233 are existing technology, and their model number is GQGQ-32-25-N. When the lifting assembly 23 is working, when the support plate 24 carries the U-shaped rubber strip 3 and moves along the upper conveying frame 21 to the end of the conveying frame body 211, the controller issues a lifting command. The two lifting cylinders 233 at the lower end of the lifting frame 231 located at the end of the conveying frame body 211 start simultaneously, their movable ends extending vertically upwards, pushing the lifting frame 231 up to the desired height. At a position flush with the upper conveyor frame 21, the two second conveying sections 232 at the upper end of the lifting frame 231 connect with the first conveying section 212 of the upper conveyor frame 21. The first conveying section 212 pushes the support plate 24 onto the second conveying section 232 of the lifting frame 231. Then, the lifting cylinder 233 drives the lifting frame 231 to descend to a position flush with the lower conveyor frame 22. The second conveying section 232 reverses its movement and pushes the support plate 24 onto the lower conveyor frame 22, completing the switching of the support plate 24 from the upper layer to the lower layer. When the support plate 24 runs along the lower conveyor frame 22 to the starting end of the conveyor frame body 211, the lifting frame 231 at the starting end rises to a position flush with the lower conveyor frame 22 under the drive of the lifting cylinder 233. After receiving the support plate 24 from the lower conveyor frame 22, it descends to a position flush with the upper conveyor frame 21. Then, the second conveying section 232 pushes the support plate 24 onto the upper conveyor frame 21, completing the switching of the support plate 24 from the lower layer to the upper layer.

[0066] like Figure 16 and Figure 17 As shown, the support plate 24 includes a support plate body 241, a vacuum plate 242, a positioning frame 243, and a vacuum interface 244. The support plate body 241 is provided on the first conveying part 212. The vacuum plate 242 is fixedly installed on the upper end of the support plate body 241. The positioning frame 243 is provided on the vacuum plate 242. The U-shaped adhesive strip 3 is placed in the positioning frame 243. The vacuum plate 242 is provided with multiple suction holes 2421, all of which are located in the positioning frame 243. The vacuum interface 244 is provided on the upper end of the vacuum plate 242 and is connected to the multiple suction holes 2421. In the support plate 24, the U-shaped adhesive strip 3 is placed in the positioning frame 243 on the upper end of the vacuum plate 242. The positioning frame 243 limits the position of the U-shaped adhesive strip 3. The vacuum interface 244 is connected to a vacuum pump. After vacuuming, the U-shaped adhesive strip 3 is adsorbed and fixed in the positioning frame 243 through the multiple suction holes 2421 on the vacuum plate 242.

[0067] The working process of a sealing strip stacking device:

[0068] First, place the U-shaped adhesive strip 3 in the positioning frame 243 of the support plate 24. The positioning frame 243 limits the position of the U-shaped adhesive strip 3. The vacuum interface 244 is connected to a vacuum pump. The U-shaped adhesive strip 3 is adsorbed and fixed in the positioning frame 243 through multiple suction holes 2421 on the vacuum plate 242.

[0069] The dual-axis motor 216 starts and drives the conveyor wheel 213 to rotate through the shaft 215. The upper end of the conveyor belt 214 adheres to the bottom surface of the support plate 24 and drives the support plate 24 to move forward along the upper conveyor frame 21, so that the U-shaped adhesive strip 3 passes through the glue application device 4 and the bonding device 6 in sequence.

[0070] When the U-shaped adhesive strip 3 arrives at the glue application station, the clamping cylinder 253 of the clamping part 25 is activated, pushing the clamping plate 251 to clamp and fix the support plate 24. The controller drives the second three-way moving platform 411 to move the glue application head 414 to a predetermined position above the U-shaped adhesive strip 3. The glue flows out from the lower end of the glue application head 414 and is applied to the surface of the U-shaped adhesive strip 3.

[0071] After the adhesive is applied, the clamping cylinder 253 drives the clamping plate 251 to reset and release the support plate 24. The U-shaped adhesive strip 3 continues to move forward into the heating box 421. The heating wire 422 is energized and heats up. The fan 423 blows hot air into the heating box 421 through the air outlet 4211 to heat the adhesive on the surface of the U-shaped adhesive strip 3 and keep it in a molten state.

[0072] When the U-shaped adhesive strip 3 reaches the bonding station, the clamping part 25 clamps and fixes the support plate 24 again. The transverse bonding component 61 first bonds the closed end of the U-shaped adhesive strip 3, and the longitudinal bonding component 62 bonds the two open ends of the adhesive strip 3. The transverse bonding component 61 and the two longitudinal bonding components 62 work together to complete the bonding operation of the thin sheet 5.

[0073] After bonding is completed, the clamping cylinder 253 resets and releases the support plate 24. The support plate 24 continues to move forward to the end of the upper conveyor frame 21 and enters the lifting frame 231 located at the end of the upper conveyor frame 21. At this time, the bonded adhesive strip 3 can be taken out. The lifting cylinder 233 drives the lifting frame 231 to descend to be flush with the lower conveyor frame 22. The second conveying part 232 runs in the opposite direction to push the support plate 24 onto the lower conveyor frame 22. The support plate 24 is transported back to the starting end along the lower conveyor frame 22. The starting end lifting frame 231 switches the support plate 24 from the lower conveyor frame 22 back to the upper conveyor frame 21, realizing the circulation of the support plate 24 and continuously transporting the U-shaped adhesive strip 3 to each process station.

[0074] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
