Description

[0002] In existing sheet metal assembly production lines, the feeding and conveying devices often suffer from problems such as unstable adsorption of non-adhesive sheets, low conveying efficiency, and poor equipment adaptability.

[0003] Although there are cases of using adhesive-bonded boards for transportation, the uneven distribution of suction cups on the adsorption components leads to uneven adsorption force distribution, further reducing the stability and reliability of adhesive-free board adsorption. Furthermore, the design of the glue-coating head in traditional glue-coating machines is often not precise enough, resulting in uneven distribution of glue orifices and uneven glue distribution on the material, forming discontinuous glue lines and affecting glue-coating quality.

[0057] The first adsorption board loading machine 1 and the second adsorption board loading machine 2 transfer the board to the first conveying device 3, where it is sprayed by the glue spraying machine 4 and conveyed in layers by the layering device to the receiving conveying device 6 for preliminary bonding. The third adsorption board loading machine 9 then adsorbs the glue-free board 98 onto its upper side to complete the final bonding, which improves production efficiency and quality stability.

[0058] Preferably, the assembly also includes a stacking machine 7 for receiving the pre-bonded boards and the glue-free boards 98. The stacking machine 7 includes a stacking lifting mechanism and a stacking conveying mechanism disposed on the stacking lifting mechanism. The first layer of boards is first moved to the stacking conveying mechanism, and then the second layer of boards is moved to the first layer of boards. Subsequently, the glue-free boards 98 are moved to the second layer of boards by the third adsorption board loading machine 9 to complete a board product. During this process, the boards are lowered by the stacking lifting mechanism and then stacked in a cycle. The board products are then moved laterally to the outer conveyor table 8 by the stacking conveying mechanism for unloading, which reduces manual operation and improves overall production efficiency.

[0059] like Figure 2 and Figure 3 As shown, the first suction plate mounting machine 1 includes a first frame 11, a first linear drive device 12, and a first negative pressure pump 14.

The first horizontal plate 1811 extends to the left and right, and the first vertical plate 1812 extends to the front and back. The first horizontal plate 1811 and the first vertical plate 1812 are perpendicularly connected. The end of the first horizontal plate 1811 extends out of the first vertical plate 1812, and a first suction plate unit 182 is also installed at the part that extends out of the first vertical plate 1812, so that the first suction plate assembly 18 is more stable and can more flexibly adapt to materials such as wood veneer of different sizes.

[0062] Furthermore, a first distance sensor 19 for detecting the position of the wood veneer is vertically fixedly connected to the first mounting bracket 15, which can monitor the position of the wood veneer in real time, ensuring that the first suction cup 1822 accurately adsorbs the veneer, thereby improving work efficiency and accuracy.

[0063] Furthermore, the first lifting drive device 17 adopts a cylinder; the first linear drive device 12 includes a first servo motor 121, a first pulley 122 and a first belt 123. The first belt 123 is arranged parallel to the first guide rail 13 and connected to the first mounting frame 15.

[0064] Furthermore, the first frame 11 is provided with first limiting plates 110 at both the front and rear ends, which can be used to limit the maximum movement range of the first mounting frame 15, ensuring its movement range and safety on the first guide rail 13, and improving the reliability and safety of the equipment.

[0065] The second adsorption plate mounting machine 2 is similar to the first adsorption plate mounting machine 1, including a second frame, a second linear drive device, and a second negative pressure pump. A second guide rail extending in the front-to-back direction is fixedly connected to the second frame, and a second mounting frame is slidably connected to the second guide rail.

The second suction tube is installed and connected to the mounting frame, and the lower side of the second suction tube communicates with the second suction cup. The upper side of the second suction tube is connected to the second negative pressure pump through a pipe fitting.

[0066] like Figure 9 and Figure 10 As shown, the third adsorption board loading machine 9 includes a third frame 91, a conveying support device 92 for conveying the glue-free board 98, and a traveling carriage 93 for driving the glue-free board 98 forward. The traveling carriage 93 moves back and forth above the third frame 91. The conveying support device 92 is located under the traveling carriage 93. An adsorption assembly 96 is connected to the traveling carriage 93 through a first lifting device 94. A third longitudinal plate lifting device 95 is installed on the adsorption assembly 96 and connected to a dropping plate pressure assembly 97 for unloading material through the third longitudinal plate lifting device 95. Two adsorption assemblies 96 are arranged side by side under the traveling carriage 93, realizing material suction and lifting, lateral transfer and descent pushing to release the glue-free board 98, improving continuity, efficiency and stability.

[0067] Specifically, both the first lifting device 94 and the third vertical plate lifting device 95 use cylinders.

[0068] Specifically, the adsorption component 96 includes an air vent 961 for connecting to an external air source and a third suction cup 962. The third suction cup 962 is connected to the air vent 961. Each adsorption component 96 includes two air vents 961, which are arranged in parallel to each other to ensure a uniform distribution of adsorption force. This effectively prevents the adhesive-free plate 98 from slipping or shifting during the conveying process, and improves the stability and accuracy of the conveying.

[0069] Specifically, multiple third suction cups 962 are arranged on each vent pipe 961. The third suction cups 962 are evenly spaced, and each third suction cup 962 can play its role, improving the adsorption efficiency and further enhancing the adsorption stability of the adhesive-free plate 98.

[0070] Specifically, each vent pipe 961 extends to the left and right, and each vent pipe 961 is connected to a third longitudinal plate 911. The third longitudinal plate 911 is symmetrically arranged on both sides of the vent pipe 961, which enhances the overall stability of the adsorption assembly 96 and facilitates later maintenance and upkeep.

[0071] Specifically, a guide mounting plate 912 and a pusher lifting mounting plate 913 are connected between the two third longitudinal plates 911. The third longitudinal plate lifting device 95 is installed and connected to the pusher lifting mounting plate 913 to flexibly adjust the height of the drop plate pressure plate assembly 97 to adapt to the processing requirements of glue-free boards 98 of different thicknesses and sizes, and to perform suction lifting and lowering push release operations, thereby improving the versatility and flexibility of the equipment.

[0072] Specifically, a lifting connecting frame 914 is installed on the third vertical plate 911, and the output end of the first lifting device 94 is connected to the lifting connecting frame 914. The lifting connecting frame 914 drives the third vertical plate 911 and the adsorption component 96 to rise and fall. A guide shaft is also installed on the guide mounting plate 912, and a guide cylinder is installed on the traveling vehicle 93. The guide shaft and the guide cylinder are slidably connected up and down. A shock-absorbing spring is connected between the auxiliary lifting frame and the guide mounting plate 912 to improve the stability of the lifting.

[0073] Specifically, the dropping plate and pressing plate assembly 97 includes an H-shaped bracket 971 and push rods 972 connected to the front and rear ends of the H-shaped bracket 971. The push rods 972 and the H-shaped bracket 971 are flush. The third longitudinal plate lifting device 95 is connected to the middle of the H-shaped bracket 971. The push rods 972 are arranged between two adjacent air pipes 961 of the same adsorption assembly 96, so that the dropping plate and pressing plate assembly 97 can descend smoothly and accurately and press down the glue-free plate 98, realizing the unloading operation of the glue-free plate 98, while avoiding damage to the glue-free plate 98 or equipment failure caused by improper unloading.

[0074] Specifically, the traveling vehicle 93 includes a frame 931, a traveling drive motor 932, a drive shaft 933, and traveling wheels 934. The traveling drive motor 932 is mounted on the upper side of the third frame 91 and is driven and connected to the drive shaft 933. The drive shaft 933 is rotatably connected to the frame 931 and its end is connected to the traveling wheels 934. A guide wheel is mounted on the frame 931. The rotation shaft of the guide wheel is vertically set and abuts against the transverse side wall of the third frame 91, ensuring the stability and accuracy of the traveling vehicle 93 during travel and reducing equipment failures and damage to the non-adhesive plate 98 caused by deviation or jamming.

[0075] Specifically, the third frame 91 includes a support frame and a traveling frame disposed on the upper side of the support frame. The traveling frame includes a left support rod 991 and a right support rod 992 arranged parallel to each other at left and right intervals. A traveling channel is formed between the left support rod 991 and the right support rod 992. Guide wheels are arranged abutting on the right side wall of the left support rod 991 and the left side wall of the right support rod 992 to make the traveling vehicle 93 move stably in a straight line.

[0076] Specifically, a loading rack 910 is connected to the front of the support frame. The upper end of the loading rack 910 is connected to the left support rod 991 and the right support rod 992. The traveling passage extends above the loading rack 910, allowing the traveling trolley 93 to move laterally to the loading rack 910 to pick up the glue-free board 98. Then, it moves laterally to the support frame and the third longitudinal plate lifting device 95 drives the dropping plate pressing assembly 97 to push the glue-free board 98 downward, releasing the glue-free board 98 to the lower third conveying device. The third conveying device then transports the glue-free board 98 to the upper side of the second layer board.

[0077] like Figure 4 and Figure 5 As shown, the glue coating machine 4 includes a fourth frame 41, on which a glue coating conveying device 42 and a mounting box 44 are installed.

The dispensing tank 46 and the glue coating head 47 are in communication. The bottom of the glue coating head 47 has multiple rows of glue coating holes evenly distributed. The glue coating holes in each row are coaxially spaced, which can form a continuous and uniform glue line, improving the glue coating quality. The glue coating process can precisely control the height and flow rate of the glue, improving the uniformity and efficiency of glue coating. At the same time, the detachable connection structure facilitates the maintenance and replacement of the glue coating head 47, increasing the flexibility and service life of the equipment.

[0078] Specifically, the lifting drive device can be a cylinder, and the lifting connecting part 43 is made of strip steel plate.

[0079] Furthermore, the dispensing box 46 is connected to a dispensing pipe 45, which includes an inlet pipe 451, a dispensing pipe 452 and a connecting pipe 453 from top to bottom. The connecting pipe 453 is connected to the dispensing pipe 45. The inlet pipe 451 is centrally located and passes upward through the mounting box 44, which can play a guiding role and improve the stability of lifting.

[0080] Furthermore, the adhesive coating conveying device 42 includes an adhesive coating conveying drive motor 421 fixedly connected to the fourth frame 41 and a drive shaft 422, a first driven shaft 423, a second driven shaft 424, and a third driven shaft 425 rotatably connected to the fourth frame 41.

Adhesive coating pulleys 426 are sleeved and installed on the drive shaft 422, the first driven shaft 423, the second driven shaft 424, and the third driven shaft 425, and adhesive coating belts 427 are fitted on the adhesive coating pulleys 426. The adhesive coating conveying device 42 is stable and reliable, and can efficiently convey materials, ensuring the continuity of the adhesive coating process.

[0081] Furthermore, the conveyor belt encloses a central installation space, within which a collection bin 48 is provided. A collection and discharge pipe is located at the bottom of the collection bin 48. A drive shaft 422, a first driven shaft 423, a second driven shaft 424, and a third driven shaft 425 are positioned outside the collection bin 48. Multiple support plates 481 are fixedly connected to the upper side of the collection bin 48. These support plates 481 are horizontally parallel to the upper end of the adhesive-coated belt 427, and their length direction is parallel to the conveying direction. This provides stable support for the veneer and ensures high smoothness. Simultaneously, the collection bin 48 effectively collects excess and spilled adhesive, reducing cleaning work and improving the cleanliness of the working environment.

[0082] Furthermore, a return adhesive filtration device 49 is installed at the lower part of the fourth frame 41. The return adhesive filtration device 49 includes a receiving hopper 491, with a return pipe 493 connected to the lower part of the receiving hopper 491. A plate mesh 492 is installed in the receiving hopper 491, and the plate mesh 492 is inclined. A wire mesh 4921 is installed at the lower corner of the plate mesh 492. A filter screen is installed above the return pipe 493 to effectively filter out impurities and ensure the quality of the adhesive. A discharge valve is installed on the return pipe 493, and the return pipe 493 can be connected to the colloid pump through a pipeline to realize the recycling of the adhesive and reduce production costs.

[0083] like Figure 8 As shown, the layered conveying device 5 includes a lower conveyor belt 51, an upper rear conveyor belt 52, an upper front conveyor belt 53, a layered mounting frame 54, an upper lifting device 55, and an upper hinge support device 56. The front side of the upper rear conveyor belt 52 is hinged to the layered mounting frame 54, and the front side is fixed in a flipped state by the upper lifting device 55. The upper hinge support device 56 provides auxiliary support, thereby realizing flipped docking and conveying, and realizing layered conveying.

[0084] Example 2

[0085] Furthermore, such as Figure 6 and Figure 7As shown, based on Example 1, a guide head 410 for assisting in the connection of adhesive liquid into a line is detachably connected below the glue-coating hole. The guide head 410 can be connected to the glue-coating hole through an elastic buckle 4101 or other device. The guide head 410 can further ensure the continuity and uniformity of the adhesive liquid forming the glue line and improve the glue-coating quality.

[0086] Furthermore, a liquid collection port 4103 is provided above the guide head 410, and a glue outlet 4104 is provided below the guide head 410. The liquid collection port 4103 and the glue outlet 4104 are connected to form a glue collection chamber. An installation platform 4102 is provided in the glue collection chamber, and a grid plate 411 for uniformly distributing the glue is placed on the installation platform 4102. The grid plate 411 has grid holes, the width of which is smaller than the diameter of the glue application hole. Furthermore, multiple installation platforms 4102 are provided, and the sidewalls of the glue collection chamber are arc-shaped. Correspondingly, the width of the grid plate 411 gradually decreases from top to bottom, and the size of the grid holes gradually decreases. The design of the glue collection chamber helps to concentrate the glue, and the grid plate 411 can further refine the glue, making it more evenly distributed on the first layer plate or the first layer plate, improving the glue application uniformity; refining the glue and making it more evenly distributed on the material improves the glue application effect.

[0087] During the glue application process, the material is first conveyed and positioned. The material is conveyed by the glue application conveying device 42. After the material is conveyed above the glue application head 47, the glue distribution box 46 is driven to the corresponding height by the lifting drive device. During glue application, the colloid pump pumps the glue liquid, causing the glue liquid to flow out from the glue application holes of the glue application head 47 and form a coarse glue line. After passing through the glue collection chamber of the guide head 410 and the grid plate 411 in the glue collection chamber, the glue line becomes a uniform glue curtain. Then, the glue curtain is lowered to the first plate or the first layer plate by the lifting drive device. At the same time, the colloid pump prevents the glue liquid from flowing further downward. The glue liquid is collected by the receiving hopper 491 and the collection bin 48 for filtration and reuse.

[0089] Based on Embodiment 1 or Embodiment 2, a rotating rod and a shock-absorbing assembly are further provided on the lower side of the first mounting frame 15. The shock-absorbing assembly includes a bushing, a guide rod, a shock-absorbing spring, and a spring seat. The spring seat is fixedly mounted on the first mounting frame 15. The first roller 16 is connected to the end of the rotating rod. The bushing is sleeved on the middle of the rotating rod. The guide rod is fixedly mounted on the bushing. The shock-absorbing spring is sleeved on the outside of the guide rod and its upper end is connected to the spring seat. The upper end of the shock-absorbing spring is connected to the spring seat, which effectively reduces vibration during movement and improves the stability and service life of the equipment.

[0090] Furthermore, the rotating rods are arranged symmetrically about the front and rear of the first mounting frame 15, and the shock absorption components are arranged symmetrically about the left and right sides of each rotating rod, which further enhances the shock absorption effect and improves the stability and reliability of the equipment.
