Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] The following is for reference. Figures 1 to 4 This invention describes a bonding device according to an embodiment of the present invention.

[0029] like Figures 1 to 3 As shown, the bonding equipment according to an embodiment of the present invention includes: a first peeling device 100, a second peeling device 200, a first transfer mechanism 300, a dual-station feeding device 400, a receiving device 500, and a second transfer mechanism 600. The first peeling device 100 is used to peel a first product off a first composite material; the second peeling device 200 is disposed on one side of the first peeling device 100 and is used to peel a second product off a second composite material; the transfer path of the first transfer mechanism 300 passes through the first peeling device 100 and the second peeling device 200, and is used to transfer the first product onto the second product to form a finished product; the dual-station feeding device 400 is disposed on one side of the second peeling device 200 and includes a frame 410, a switching assembly 420, and a lifting assembly 430. A first workstation 44 is slidably connected to the frame 410. The first and second workstations 440 and 450 are used to alternately provide separator paper; the switching component 420 is located on the frame 410 and is used to drive the first workstation 440 and the second workstation 450 to switch workstations; the lifting component 430 is located on the frame 410 and is used to drive the second workstation 450 to lift during workstation switching so that the second workstation 450 and the first workstation 440 can be staggered in the height direction when they meet; the receiving device 500 is located on one side of the second peeling device 200 and the dual-station feeding device 400, and the receiving device 500 has a feeding position for collecting finished products and separator paper; the transfer path of the second transfer mechanism 600 passes through the second peeling device 200, the receiving device 500 and the dual-station feeding device 400, and is used to feed finished products and separator paper alternately to the receiving device 500.

[0030] Understandably, this bonding equipment includes a first peeling device 100, a second peeling device 200, a first transfer mechanism 300, a dual-station feeding device 400, a receiving device 500, and a second transfer mechanism 600. In use, the first peeling device 100 peels the first product off the first composite material. The first transfer mechanism 300 transfers the first product onto the second composite material on the second peeling device 200. Then, the second peeling device 200 peels off the second product along with the first product on the second composite material, forming a finished product. Subsequently, the second transfer mechanism 600 transfers the finished product to the unloading position of the receiving device 500, followed by dual-station feeding. The first workstation 440 in device 400 provides a separator paper so that the second transfer mechanism 600 can transfer the separator paper to the receiving device 500. When the separator paper of the first workstation 440 is used up, the second workstation 450 switches positions with the first workstation 440 under the drive of the switching component 420. During the switching process, the second workstation 450 is raised and lowered under the drive of the lifting component 430 so that it can avoid the first workstation 440 in the height direction when they meet, so that the second workstation 450 can continue to provide separator paper. Meanwhile, the first workstation 440 is replenished manually on the other side, realizing non-stop processing. Therefore, the bonding equipment of this application can realize the automated bonding process with high efficiency and no downtime.

[0031] It is understood that the first stripping device 100 and the second stripping device 200 are respectively equipped with a discharge roller 210, a stripping blade 220, a receiving platform 230, and a take-up roller 240. The discharge roller 210, stripping blade 220, and receiving platform 230 are arranged sequentially along the feeding direction of the first product / second product. The discharge roller 210 is used to discharge the first composite / second composite, the stripping blade 220 is used to peel off the first composite / second composite, the receiving platform 230 is used to receive the peeled first product / second product, and the take-up roller 240 is located below the stripping blade 220 and is used to wind up the strip at the bottom of the first composite / second composite. For example, as Figure 2 As shown, in this embodiment, both the first peeling device 100 and the second peeling device 200 are equipped with a discharge roller 210, a peeling knife 220, a receiving platform 230, and a take-up roller 240. That is, the peeling process of the first composite product and the second composite product is roughly the same. In other words, the material is first discharged from the discharge roller 210, and then peeled by the peeling knife 220. The peeled first product or second product is peeled onto the receiving platform 230, and the remaining strip is wound onto the take-up roller 240.

[0032] It is understood that the system also includes a first visual inspection mechanism 700, which is located between the first stripping device 100 and the second stripping device 200, and is used to cooperate with the first transfer mechanism 300 to adjust the posture of the first product. For example, as Figure 1 As shown in this embodiment, before the first transfer mechanism 300 transfers the first product to the second peeling device 200, it first transfers it to the first vision inspection mechanism 700 to adjust the posture of the first product, and then attaches it to the second product to align the attachment position and angle.

[0033] Understandably, it also includes a second visual inspection mechanism 800, and the second peeling device 200 is provided with a bonding position for bonding the first product and the second product. The second visual inspection mechanism 800 is positioned toward the bonding position to cooperate with the first transfer mechanism 300 so that the first product and the second product can be aligned. For example, as Figure 1 As shown, in this embodiment, after the second visual detection mechanism 800 detects that the second product has moved to the bonding position, it transmits a signal to the control system. The control system controls the first transfer mechanism 300 to bond the first product to the second product, thereby improving the bonding position and angle.

[0034] It is understood that the second stripping device 200 includes a feeding platform 250, which is located between the discharge roller 210 and the stripping blade 220. The feeding platform 250 is equipped with a limiting component 251 and a negative pressure hole 252. The limiting component 251 is used to limit the width direction of the second composite material feeding, and the negative pressure hole 252 extends vertically through the feeding platform 250 to smooth the second composite material. For example, as... Figure 2 As shown, in this embodiment, the limiting component 251 on the feeding table 250 can limit the position of the second composite in the width direction, thereby correcting the position of the second product at the bonding position to a certain extent. The negative pressure hole 252 can improve the flatness of the second product, thereby improving the yield of the bonded finished product.

[0035] Understandably, the feeding table 250 is also equipped with a roller pressing assembly 253, which is located between the bonding position and the peeling blade 220 and is used to extrude the finished product to remove air bubbles. For example, as Figure 2 As shown, in this embodiment, the roller pressing assembly 253 can press the bonded finished products together, squeeze out the air bubbles between the first product and the second product, and improve the tightness of the bond.

[0036] Understandably, the switching assembly 420 includes a driving wheel, a driven wheel, a conveyor belt 421, and a second drive unit. The driving wheel and the driven wheel are connected by the conveyor belt 421. The second drive unit drives the driving wheel to rotate. A first workstation 440 is connected to one side of the conveyor belt 421, and a second workstation 450 is connected to the other side of the conveyor belt 421. For example, as... Figures 3 to 4As shown, in this embodiment, the two sections of the conveyor belt 421 are arranged side by side, and the first workstation 440 is connected to one side of the conveyor belt 421, and the second workstation 450 is connected to the other side of the conveyor belt 421. The transmission of the conveyor belt 421 and the switching of the positions of the first workstation 440 and the second workstation 450 are realized through the second driving member, the driving wheel and the driven wheel.

[0037] Understandably, the frame 410 is equipped with a worktable 411 and a connecting assembly. A first worktable 440 and a second worktable 450 are slidably connected to the worktable 411. The worktable 411 has a clearance groove 4111 arranged along the length of the conveyor belt 421. The connecting assembly can slide along the clearance groove 4111. The second worktable 450 is connected to the other side of the conveyor belt 421 via the connecting assembly, and the second worktable 450 is vertically slidably connected to the connecting assembly. For example, as... Figures 3 to 4 As shown, in this embodiment, the second workstation 450 is connected to the other side of the conveyor belt 421 through a connecting component. The second workstation 450 is vertically slidably connected to the connecting component, and the connecting component slides along the clearance groove 4111 on the worktable 411 of the frame 410, thereby achieving clearance with the first workstation 440, and thus achieving clearance between the second workstation 450 and the first workstation 440.

[0038] It is understood that the connecting assembly includes a second clamping plate 4121, a first connecting plate 4122, a second connecting plate 4123, and a guide slide plate 4124 connected in sequence. The second clamping plate 4121 clamps the other side of the connecting conveyor belt 421 and can slide along the clearance groove 4111. The first connecting plate 4122 is connected to the bottom of the second clamping plate 4121 and slides below the worktable 411. The second connecting plate 4123 is connected to both ends of the first connecting plate 4122 and is located on the outer side of the worktable 411 in the width direction. The guide slide plate 4124 is slidably connected to the worktable 411 and connected to the upper part of the second connecting plate 4123. The second worktable 411 is vertically slidably connected to the second connecting plate 4123. For example, as Figures 3 to 4As shown, in this embodiment, the connecting assembly includes a second clamping plate 4121, a first connecting plate 4122, a second connecting plate 4123, and a guide slide plate 4124. The second clamping plate 4121 clamps the other side of the conveyor belt 421 and is connected to the first connecting plate 4122 located at the bottom of the workbench 411 through an avoidance groove 4111. The two ends of the first connecting plate 4122 are respectively connected to the second connecting plate 4123. The upper part of the second connecting plate 4123 is respectively connected to the guide slide plate 4124. The guide slide plate 4124 is slidably connected to the workbench 411. Thus, during the workstation switching process, the connecting assembly drives the second workstation 450 to move horizontally under the drive of the conveyor belt 421. During the horizontal movement, the second workstation 450 can be raised by the drive of the lifting assembly 430, and the two sides of the bottom of the second workstation 450 avoid the outside of the first workstation 440, thereby realizing the avoidance switching.

[0039] Specifically, the guide slide plate 4124 is also provided with a through hole, and the bottom of the second workstation 450 is movably inserted through the through hole, so as to move freely up and down.

[0040] It is understood that the lifting assembly 430 includes a support frame 431, a follower 432, and a guide plate 433. The follower 432 is connected to the bottom of the second workstation 450 via the support frame 431. The guide plate 433 has a guide groove 4331 along the conveying direction of the conveyor belt 421. The guide groove 4331 is higher in the middle and lower at both ends, allowing the follower 432 to slide along the guide groove 4331. For example, as... Figures 3 to 4 As shown, in this embodiment, the support frame 431 at the bottom of the second workstation 450 abuts against the guide groove 4331 of the guide plate 433 through the follower 432. Since the guide groove 4331 is high in the middle and low at both ends along the length of the conveyor belt 421, the second workstation 450 can rise first and then fall during the workstation switching process.

[0041] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
