The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0026] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, according to Figure 1-6 As shown, it includes: a support 100, on which a gluing device 200, a conveying device 300, and two transfer devices 400 are mounted; the conveying device 300 includes an upper conveyor belt 310, a lower conveyor belt 320, and a first motor assembly 330 for driving the upper conveyor belt 310 and the lower conveyor belt 320; the first end of the upper conveyor belt 310 is connected to the gluing device 200, the gluing device 200 is connected to the lower conveyor belt 320 through a transfer device 400, the lower conveyor belt 320 passes through the gluing device 200, and the second end of the upper conveyor belt 310 is connected to the lower conveyor belt 320 through another transfer device 400, thus connecting the upper conveyor belt 310, the lower conveyor belt 320, and the gluing device 200 through the transfer devices 400.

[0030] The upper conveyor belt 310 is equipped with a material plate 500, which is used to place materials. The glue applicator 200 is used to apply glue to the materials. It can be understood that the material plate 500 is light-transmitting and air-transmitting. Furthermore, the air-transmitting can be achieved by setting air holes on the material plate 500, and the light-transmitting can be achieved by using a light-transmitting material.

[0031] The material board 500 can be moved to the gluing device 200 under the drive of the upper conveyor belt 310 to apply glue to the material. After gluing, it is transferred to the lower conveyor belt 320 for transportation and drying via the transfer device 400. Then, it is transferred back to the upper conveyor belt 310 via another transfer device 400 for material processing and bonding.

[0032] The specific working steps are as follows: The worker places the material on the material plate 500 and fixes it. Then, the material plate 500 is placed on the upper conveyor belt 310 near the end of the gluing device 200. The material plate 500 is conveyed to the gluing platform 220 for gluing by the conveyor device 230. Then, it is transferred to a transfer device 400 by the conveyor device 230. The transfer device 400 transfers it to the lower conveyor belt 320. The lower conveyor belt 320 passes through the bottom of the gluing device 200 and is connected to the upper conveyor belt 310 at the end away from the gluing device 200 by another transfer device 400. The support 100 is equipped with multiple workbenches 110. Each workbench 110 is located above the upper conveyor belt 310. Some workbenches 110 are convenient for workers to glue the material after it has been left to dry for a while. Some workbenches 110 are used to fix the un-glued material on the material plate 500.

[0033] Furthermore, by setting up a conveyor device 300 and a transfer device 400, the material after being coated with adhesive is conveyed and dried for a certain period of time before being transported back to the upper conveyor belt 310 for bonding. Workers do not need to take the material elsewhere to dry before bonding, saving time and costs associated with manual handling. At the same time, the drying process is automated, improving production efficiency. The vertical setting of the upper and lower conveyor belts can save the machine's floor space. Drying the material for a certain period of time after coating with adhesive can make the bonding stronger and prevent slippage during bonding.

[0034] Furthermore, the first motor assembly 330 and the second motor assembly 440 are conventional motor roller combinations, as long as they can drive the upper conveyor belt 310, the lower conveyor belt 320, and the transfer conveyor belt 430 for transportation.

[0035] In another embodiment of this utility model, such as Figure 2 and 3 As shown, the transfer device 400 includes a lifting platform 410; the lifting platform 410 is raised and lowered by a first drive device 420. A transfer conveyor belt 430 is provided on the lifting platform 410, and the transfer conveyor belt 430 is driven to rotate and transport by a second motor assembly 440.

[0036] Furthermore, the first driving device 420 includes a third motor assembly 421 and a rotating shaft 422; the third motor assembly 421 drives the rotating shaft 422 to rotate, and gears 423 are provided at both ends of the rotating shaft 422. Two lifting chains 424 are provided on the bracket 100 at positions corresponding to the two gears 423. Each lifting chain 424 is wound around the gear 423. The lifting chains 424 are connected to the lifting platform 410. The rotation of the rotating shaft 422 can drive the lifting platform 410 to rise and fall through the gears 423 and the lifting chains 424.

[0037] The specific transfer steps are as follows: When the material plate 500 leaves the glue-coating platform 220 under the action of the conveyor device 230, the first drive device 420 drives the lifting platform 410 to rise, reaching approximately the same height as the conveyor device 230, transporting the material plate 500 onto the lifting platform 410. The lifting platform 410 then descends under the drive of the first drive device 420, reaching the same height as the lower conveyor belt 320. The transfer conveyor belt 430 rotates under the second motor assembly 440, transporting the material plate 500 onto the lower conveyor belt 320. The lower conveyor belt 320 then transports the material plate 500 to another transfer device 400 for transfer to the upper conveyor belt 310. The transfer device 400 is used to transfer material plates 500 on different planes, utilizing vertically arranged upper and lower conveyor belts to save machine floor space and allow for the drying of glued materials.

[0038] Furthermore, the driving principle of the first driving device 420 is that the rotation of the third motor assembly 421 drives the rotation of the rotating shaft 422, which in turn drives the gears 423 located at both ends of the rotating shaft 422 to rotate. The lifting chain 424 is meshed with the gears 423 respectively. The rotation of the gears 423 can drive the lifting chain 424 to rotate. The lifting chain 424 is fixedly connected to the lifting platform 410, which can drive the lifting platform 410 to move up and down. Furthermore, it can be understood that the third motor assembly 421 can rotate in both directions, so that the lifting platform 410 connected to the lifting chain 424 can rise and fall. The above are conventional technologies that can be understood and are well known to those skilled in the art, and their principles and specific structures will not be described in detail here.

[0039] Furthermore, the lifting platform 410 is provided with guide members 450 on both sides. One side of the guide member 450 is connected to the lifting chain 424. The guide member 450 has symmetrically arranged guide wheels 451. The bracket 100 is provided with a guide rail 452. At least one pair of guide wheels 451 are symmetrically arranged on both sides of the guide rail 452. The guide member 450 plays a guiding and assisting role in lifting, which can make the lifting platform 410 more stable during the lifting process.

[0040] In another embodiment of this utility model, according to Figure 4-6 As shown, the gluing device 200 includes a gluing assembly 210 mounted on a support 100; a gluing platform 220 is provided under the gluing assembly 210, and conveying devices 230 are provided on both sides of the gluing platform 220. The material plate 500 can be conveyed from the upper conveyor belt 310 to the conveying device 230 and enters and leaves the gluing platform 220 under the action of the conveying device 230. After the material plate 500 enters the material platform, the gluing assembly 210 applies glue to the material on the material plate 500. After completion, it leaves the gluing platform 220 under the action of the conveying device 230 and enters the lower conveyor belt 320 through the transfer device 400.

[0041] Furthermore, the adhesive application assembly 210 includes an adhesive application head 211 and a moving assembly 212; the moving assembly 212 controls the movement of the adhesive application head 211. The moving assembly 212 is a conventional three-axis moving device, which can be a combination of a motor lead screw, a motor slide rail, etc., and will not be described in detail here. The adhesive application assembly 210 also includes an adhesive pumping structure, etc., which will also not be described in detail here.

[0042] Furthermore, the conveying device 230 can be a slide rail conveyor, a belt conveyor, or a roller conveyor, etc. Any device that can convey the material plate 500 is acceptable. Preferably, a roller conveyor 230 is selected. Two sets of rollers on both sides clamp the two ends of the material plate 500 and push it to convey. The rollers are driven to rotate by a belt. Each set of rollers is divided into upper and lower layers, which clamp the material plate 500 to move. The roller conveyor 230 is also a mature existing technology and will not be described in detail here.

[0043] In another embodiment of this utility model, according to Figure 6 As shown, the bottom of the gluing platform 220 is provided with a cavity 240, and the surface of the gluing platform 220 is provided with an opening 221 communicating with the cavity 240. The bracket 100 is provided with a negative pressure device 250, which is interconnected with the cavity 240. The negative pressure device 250 is used to adsorb the material plate 500 tightly onto the gluing platform 220, preventing the material plate 500 from moving when the gluing assembly 210 is working. Specifically, the negative pressure device 250 can be a bellows, which creates a negative pressure inside the cavity 240, causing air to be drawn in at the opening 221, generating suction to fix the material plate 500 on the gluing platform 220. During gluing, the material plate 500 slips, generating more waste material and increasing the yield rate.

[0044] In another embodiment of this utility model, according to Figure 6 As shown, the bottom of the adhesive application platform 220 is equipped with a light source assembly 260, and the adhesive application assembly 210 includes a vision component (not shown). Through the light source assembly 260 and the vision component, adhesive can be applied to the material on the material plate 500 using visual means. Specifically, this device is a backlit vision solution, and the vision component can be a camera. During adhesive application, the backlight can generate shadows, which represent the shape of the material, allowing the vision component to apply adhesive to the material.

[0045] In another embodiment of this utility model, according to Figure 4 and 5As shown, the support 100 is also equipped with a blocking cylinder 270, which is located below the material plate 500. The lever of the blocking cylinder 270 can move closer to or away from the material plate 500 to control the stationary and moving states of the material plate 500. The blocking cylinder 270 allows for targeted adjustment of the material plate 500. Since the conveying device 230 can move all material plates 500, it's possible for the next material plate 500 to arrive at the gluing platform 220 before the previous coating process is completed. The blocking cylinder 270 prevents this by blocking the next material plate 500 outside the gluing platform 220. After the previous material plate 500 is completed, the lever of the blocking cylinder 270 moves away from the material plate 500, releasing control and allowing it to move under the action of the conveying device 230 and be transported to the gluing platform 220.

[0046] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
