[0017] 1. This invention automatically applies double-sided adhesive to the product and removes the film from the double-sided adhesive through a first adhesive applicator. A steel sheet applicator then applies a steel sheet to the product. A conveyor line moves the product to a second applicator position where double-sided adhesive is applied to the steel sheet on the product, and the applicator checks the quality of the applied steel sheet.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0034] like Figure 1 —The embodiment shown in 11:

[0035] A steel sheet laminating machine includes a frame 1, with a conveyor line 2 on the upper surface of the frame 1. The conveyor line 2 has a first laminating position and a second laminating position. A lifting and shaping mechanism 6 is located below both the first and second laminating positions. A first adhesive applicator 3 and a steel sheet laminating mechanism 4 are respectively located on either side of the first laminating position on the conveyor line 2. The first adhesive applicator 3 applies double-sided adhesive to the product and peels off the film on the other side of the double-sided adhesive. A pallet loading / unloading assembly 8 is located at the input position of the steel sheet laminating mechanism 4, providing steel sheets to the steel sheet laminating mechanism 4 and transferring an empty pallet for loading the steel sheets. A second adhesive applicator 5 is located on one side of the second laminating position on the conveyor line 2, applying double-sided adhesive to the steel sheets laminating by the steel sheet laminating mechanism 4 and detecting whether the lamination is qualified. An NG deflection assembly 7 is also located at the second laminating position, deflecting the detected defective products to distinguish between defective and good products on the conveyor line 2.

[0036] See Figure 1 As shown, the product to be fitted with a steel sheet is transferred to the first attachment position via conveyor line 2. Then, the lifting and shaping mechanism 6 shapes and fixes the product. Next, the first adhesive applicator 3 applies double-sided adhesive to the predetermined position on the product. Since the other side of the double-sided adhesive has a bottom film, this film needs to be removed. The first adhesive applicator 3 removes the film from the double-sided adhesive on the product. At this time, the steel sheet attachment mechanism 4 picks up the steel sheet from the pallet loading and unloading assembly 8. Then, the picked-up steel sheet is attached to the top adhesive on the product. The double-sided adhesive is used to bond and fix the steel sheet to the product, thus completing the first process of attachment.

[0037] After the first attachment process is completed, the lifting and shaping mechanism 6 returns to its initial position. Then, the product with the attached steel sheet is transferred to the second attachment position via conveyor line 2. Since the steel sheet is needed to connect two components and improve connection strength, double-sided tape is also applied to the steel sheet to connect the other components. At the second attachment position, the lifting and shaping mechanism 6 at that position corrects the product's position. Then, the second tape application mechanism 5 applies double-sided tape to the upper surface of the steel sheet on the product. After application, the attached steel sheet is inspected by the detection components of the second tape application mechanism 5. If the inspection is successful, the product position remains unchanged; otherwise, the NG steering assembly 7 rotates the product 90 degrees. The different positions and orientations of successful and unsuccessful products distinguish between them. After the lifting and shaping mechanism 6 returns to its initial position, both successful and unsuccessful products are conveyed to the next process. During conveying, unsuccessful products are discarded, leaving only successful products for the next process.

[0038] In this embodiment, since the lifting and shaping mechanism 6 is required to lift the product upwards, the conveyor line 2 uses a roller conveyor belt for conveying. Each roller has a protective pad, specifically a rubber pad, to prevent the product from being damaged during the conveying process.

[0039] The first adhesive application mechanism 3 includes a first three-axis module 31 mounted on a base on the frame 1, a first adhesive feeder 33 on one side of the first three-axis module 31, and an adhesive application and film removal assembly 32 mounted on the power output end of the first three-axis module 31. The adhesive application and film removal assembly 32 includes a first mounting plate 321 fixedly mounted on the power output end of the first three-axis module 31. A first rotary motor 322 is fixedly mounted on the front of the first mounting plate 321. A first suction plate 323 is mounted on the power output end of the first rotary motor 322. A first CCD component 326 located on one side of the first rotary motor 322 is also mounted on the front of the first mounting plate 321. A first lifting cylinder 324 is fixedly mounted on the side of the first mounting plate 321. A film removal pneumatic gripper 325 for film removal is mounted on the power output end of the first lifting cylinder 324.

[0040] See Figure 2 As shown, when double-sided tape needs to be applied, the first three-axis module 31 moves the tape application and film removal component 32 to the position of the first adhesive feeder 33. Under the linkage of the first three-axis module 31, the first adhesive feeder 33, and the first mounting plate 321, the first suction plate 323 contacts the double-sided tape and adsorbs it. Next, the first three-axis module 31 moves the first suction plate 323 with the adsorbed double-sided tape to the product above the first attachment position. The first CCD component 326 takes a picture of the product to determine the attachment position. Under the linkage of the first three-axis module 31 and the first rotary motor 322, the double-sided tape adsorbed by the first suction plate 323 is attached to the product. After the application is completed, under the linkage of the first three-axis module 31, the first lifting cylinder 324, and the film removal pneumatic gripper 325, the surface release film on the double-sided tape on the product is peeled off, exposing the adhesive side of the double-sided tape, which facilitates the subsequent attachment of the steel sheet.

[0041] The steel sheet attaching mechanism 4 includes a second three-axis module 41 mounted on a base on the frame 1. A steel sheet attaching assembly 42 is mounted on the power output end of the second three-axis module 41. The steel sheet attaching assembly 42 includes a second mounting plate 421 mounted on the power output end of the second three-axis module 41. A second rotary motor 422 is fixedly mounted on the front of the second mounting plate 421. A second suction plate 423 is mounted on the power output of the second rotary motor 422. A second CCD assembly 424 located on one side of the second rotary motor 422 is also fixedly mounted on the front of the second mounting plate 421.

[0042] See Figure 3As shown, firstly, under the linkage of the second three-axis module 41 and the second rotary motor 422, the second suction plate 423 is transported to the feeding point. The position of the steel sheet is determined by taking a picture of the steel sheet through the second CCD module 424. Then, under the linkage of the second three-axis module 41 and the second rotary motor 422, the steel sheet provided by the tray loading and unloading assembly 8 is adsorbed by the second suction plate 423. After the steel sheet is adsorbed, the second suction plate 423 with the adsorbed steel sheet is transferred to the product through the second three-axis module 41. The position to be attached is determined by taking a picture of the second CCD assembly 424. Then, the steel sheet adsorbed by the second suction plate 423 is attached to the double-sided tape through the linkage of the second three-axis module 41 and the second rotary motor 422.

[0043] The second adhesive applicator 5 includes a third three-axis module 51 mounted on the frame 1 and located on the base frame at the second attachment position. An adhesive applicator assembly 52 is fixedly mounted on the power output end of the third three-axis module 51, and a second adhesive feeder 53 is provided on one side of the adhesive applicator assembly 52.

[0044] See Figure 1 The adhesive applicator 52 and the steel sheet applicator 42 have the same structure. The difference is that the second CCD component 424 can not only take pictures to determine the applicator position, but also inspect the applicated product to check whether the applicator is qualified. The adhesive applicator 52 is moved to the second adhesive feeder 53 by the third three-axis module 51 to adsorb the double-sided adhesive. Next, the second suction plate 423 is moved to the product position by the third three-axis module 51. The second CCD component 424 in the adhesive applicator 52 takes pictures to determine the applicator position, and under the linkage of the second rotary motor 422 and the third three-axis module 51, the double-sided adhesive adsorbed by the second suction plate 423 is applied to the steel sheet, thus completing the application. After the application is completed, the second CCD component 424 checks whether the product is qualified.

[0045] The NG steering assembly 7 is fixedly installed on the other side of the crossbeam of the third three-axis module 51. The NG steering assembly 7 includes a third lifting cylinder 71 fixedly installed on the crossbeam of the third three-axis module 51. A rotary cylinder 72 is fixedly installed at the power output end of the third lifting cylinder 71. A rotary plate 73 is fixedly installed at the power output end of the rotary cylinder 72. Several first suction cups 74 are fixedly installed on the rotary plate 73.

[0046] See Figure 1 and Figure 4As shown, when the second adhesive applicator 5 detects a defective product, it first drives the NG steering component 7 to the product location via the third three-axis module 51. Through the linkage of the third three-axis module 51 and the third lifting cylinder 71, the first suction cup 74 is transferred to the product location and adsorbs the product. Then, the product is moved upward, and the rotary cylinder 72 is activated to rotate the adsorbed product 90 degrees. Next, the defective product that has been rotated 90 degrees returns to its initial position. Since the defective product is rotated 90 degrees and its placement position is different from that of the qualified product, the qualified product and the defective product can be clearly distinguished, which facilitates the subsequent process to remove the defective product and retain only the qualified product.

[0047] The pallet loading and unloading assembly 8 includes a loading pallet lifting mechanism 81 located at the feeding position of the steel sheet attaching mechanism 4 and a unloading pallet lifting mechanism 82 located on one side of the loading pallet lifting mechanism 81. A pallet handling mechanism 83 for handling empty pallets from the loading pallet lifting mechanism 81 is provided between the loading pallet lifting mechanism 81 and the unloading pallet lifting mechanism 82.

[0048] See Figure 1 The pallet containing steel sheets is first placed on the loading pallet lifting mechanism 81, and then the pallet is raised by the loading pallet lifting mechanism 81 and transferred to the pallet transfer component 9. After the steel sheet attaching mechanism 4 attaches the steel sheets in the pallet, the empty pallet is transferred to the unloading pallet lifting mechanism 82 for collection by the pallet handling mechanism 83, thus realizing automatic loading and unloading. Specifically, the pallet containing steel sheets can be manually moved to the loading pallet lifting mechanism 81, and the empty pallet can be manually moved out from the unloading pallet lifting mechanism 82.

[0049] The loading pallet lifting mechanism 81 and the unloading pallet lifting mechanism 82 have the same structure. The loading pallet lifting mechanism 81 includes a third mounting plate 811 installed on the frame 1. The front of the third mounting plate 811 is provided with a lifting linear module 812. The power output end of the lifting linear module 812 is fixedly connected to a lifting pallet 813. The pallet handling mechanism 83 includes a handling linear module 831 fixedly installed on the upper surface of the frame 1. The power output end of the handling linear module 831 is fixedly installed with a fourth lifting cylinder 832. The output end of the fourth lifting cylinder 832 is provided with an extension frame 833. The bottom surface of the extension frame 833 is equipped with a second suction cup 834 adapted to the pallet.

[0050] A pallet transfer assembly 9 is provided between the pallet lifting mechanism 81 and the steel sheet attaching mechanism 4. The pallet transfer assembly 9 includes a guide rail 91 mounted on the frame 1. A sliding plate 92 is slidably mounted on the guide rail 91. A transfer cylinder 93 is also mounted on the upper surface of the frame 1, and the power output end of the transfer cylinder 93 is fixedly connected to the sliding plate 92. A number of locking blocks 94 distributed in the shape of a pallet are provided on the sliding plate 92.

[0051] See Figure 5 , Figure 6 and Figure 7 As shown, by activating the loading pallet lifting mechanism 81, the pallet stack containing steel sheets on the lifting pallet plate 813 is lifted. After it rises to the highest position, the fourth lifting cylinder 832 is activated to move the second suction cup 834 to the pallet containing steel sheets and to hold the loading pallet up. At this time, the transfer cylinder 93 is activated to move the sliding plate 92 to the bottom of the pallet held by the second suction cup 834. Then, the fourth lifting cylinder 832 drives the second suction cup 834 to descend so that the pallet containing steel sheets is placed in the pallet-shaped clamping blocks 94. Next, the transfer cylinder 93 drives the sliding plate 92 to the feeding position of the steel sheet attaching mechanism 4, so that the steel sheet attaching mechanism 4 can attach the steel sheets.

[0052] After the steel sheet in the tray located in the sliding plate 92 is attached, the empty tray on the sliding plate 92 is moved to below the second suction cup 834 by the transfer cylinder 93. The fourth lifting cylinder 832 is activated to pick up and lift the empty tray. Driven by the transport linear module 831, the empty tray picked up by the second suction cup 834 is transferred to the unloading tray lifting mechanism 82 for collection. The unloading tray lifting mechanism 82 will descend the corresponding height for each empty tray it picks up. The above is the process of loading one tray. The above operation is repeated when loading and unloading other trays.

[0053] The lifting and shaping mechanism 6 includes a lifting frame 61 fixedly installed on the frame 1. Side plates 63 are slidably arranged on both sides of the lifting frame 61. A lifting platform 64 is arranged above the lifting frame 61 and is fixedly connected to the side plates 63. A second lifting cylinder 66 is fixedly installed on the bottom plate of the lifting frame 61 and the power output end of the second lifting cylinder 66 is fixedly connected to the bottom surface of the lifting platform 64. A blocking component 62 is arranged in the output direction of the conveyor line 2 and at the end of the lifting platform 64. The blocking component 62 includes a blocking cylinder 621 installed on the upper surface of the frame 1. A blocking plate 622 is fixedly installed on the power output end of the blocking cylinder 621 and a plurality of evenly distributed blocking supports 623 are installed on the blocking plate 622.

[0054] See Figure 8 and Figure 9When the conveyor line 2 transports the product from the inlet to the attachment position, the first step is to activate the blocking cylinder 621 to raise the blocking plate 622 and the blocking support 623, preventing the product from continuing to move. Then, the second lifting cylinder 66 is activated to raise the lifting platform 64, lifting the product on the conveyor line 2. After the lifting is completed, the shaping component 65 is activated to correct the position of the product on the lifting platform 64. After the correction is completed, the suction plate set on the lifting platform 64 holds the product in place to prevent the product from moving during the application of adhesive and steel sheet. After the adhesive and steel sheet are applied to the product, the above steps are reversed to place the product back on the conveyor line 2 and transport it to the next attachment position.

[0055] A shaping component 65 is provided below the lifting platform 64. The shaping component 65 includes a shaping mounting base 651 fixedly installed on the lower surface of the lifting platform 64. The shaping mounting base 651 has a mounting cavity 652 inside. A shaping cylinder 653 is fixedly installed on the inner top wall on both sides of the mounting cavity 652. A support plate 655 is fixedly connected to the power output end of the shaping cylinder 653. Multiple evenly distributed shaping feet 656 are fixedly installed on each support plate 655. A sliding plate 654 is slidably connected to both sides of the bottom surface of the shaping mounting base 651, and the upper end of the sliding plate 654 is fixedly connected to the support plate 655.

[0056] See Figure 10 and Figure 11 After the lifting platform 64 has lifted the product, the two shaping cylinders 653 are activated to drive the two support plates 655 and the shaping feet 656 to move closer to each other, thereby correcting the position of the product and facilitating subsequent attachment.

[0057] In this embodiment, the first three-axis module 31, the second three-axis module 41, and the third three-axis module 51 can realize movement in the X, Y, and Z directions. Specifically, they can be composed of three linear drive components such as motor lead screw linear modules or motor synchronous belt linear modules and linear motor modules. This three-axis module is a technology known to those skilled in the art, and will not be described in detail here.

[0058] The working process of this invention is as follows: The conveyor line 2 first conveys the product to the first attaching position. The product is first shaped by the lifting and shaping mechanism 6. After the shaping is completed, the first adhesive attaching mechanism 3 applies adhesive to the product and removes the film. Then, under the linkage of the loading pallet lifting mechanism 81 and the pallet transporting mechanism 83, the pallet containing the steel sheet is transferred to the pallet transfer assembly 9. The pallet transfer assembly 9 transfers the pallet containing the steel sheet to the feeding position of the steel sheet attaching mechanism 4. The steel sheet attaching mechanism 4 adsorbs the steel sheet in the pallet on the pallet transfer assembly 9 and attaches the steel sheet to the product.

[0059] After the steel sheet is attached, the lifting and shaping mechanism 6 returns to its initial position. The product with the steel sheet attached is transferred to the second attachment position via the conveyor line 2. At the second attachment position, the lifting and shaping mechanism 6 first corrects the position of the product. After correction, the second adhesive applicator 5 applies double-sided tape to the steel sheet (the surface film of the double-sided tape is not removed). After the double-sided tape is applied, the product is inspected to see if the attachment is qualified. If it is qualified, the lifting and shaping mechanism 6 returns to its initial position and is conveyed to the next process via the conveyor line 2. If it is unqualified, the lifting and shaping mechanism 6 stops adsorbing the product, and the NG steering component 7 rotates the product 90 degrees. After the rotation is completed, the lifting and shaping mechanism 6 returns to its initial position and is conveyed to the next process via the conveyor line 2. The placement of unqualified and qualified products is different, which makes it easier to distinguish between defective and good products and facilitates the subsequent rejection of defective products.

[0060] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
