Description

Technical Field

[0001] This application relates to the field of absorbent products technology, and in particular to an absorbent core bonding device. Background Technology

[0002] Absorbent products are a class of products that can absorb and contain liquids, semi-liquids, and other substances. In daily life, absorbent products can be used to absorb substances such as biological excretions or wound exudates, and are widely used in medical, personal care, and pet care fields.

[0003] Absorbent materials generally consist of a top layer for contact with biological surfaces (such as skin), an absorbent core for absorbing and containing the absorbed substances, and a bottom layer that acts as an impermeable barrier. During production, the materials for each layer need to be fed and cut separately before being combined.

[0004] Taking the bonding of the first layer of material in the absorbent core to the second layer of material as an example, in order to ensure the accuracy of the bonding, the second layer of material needs to be stopped during the bonding process until the first layer of material is transferred to the second layer of material. Therefore, the production process needs to be carried out intermittently, resulting in low production efficiency. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0083] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0084] This application provides an absorber core bonding device.

[0085] Please see Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the absorber core assembly. In this embodiment, the absorber core assembly includes: a transfer mechanism 50, a conveyor belt mechanism 30, and a transfer mechanism 40.

[0086] The conveyor belt mechanism 30 is used to convey the second material. In this embodiment, the conveyor belt mechanism 30 can be a vacuum suction belt, a belt, or other conveying component; specifically, the conveyor belt mechanism 30 is configured to convey the second material and provide a platform for horizontal conveying of the second material, so as to facilitate the combination of the first material and the second material.

[0087] The transfer mechanism 50 is equipped with a picking member 51 for acquiring the first material. The transfer mechanism 50 can drive the picking member 51 to move to acquire the first material, and then transfer the first material to the handover position with the transfer mechanism 40.

[0088] The transfer mechanism 40 is disposed between the conveyor belt mechanism 30 and the transfer mechanism 50, and a material picking box 41 is provided on the transfer mechanism 40. In this embodiment, the material picking box 41 can be driven by the transfer mechanism 40 to the handover position of the first material to pick up the first material on the picking member 51, and then driven by the transfer mechanism 40 to hand over the first material to the second material being conveyed.

[0089] Since the transfer mechanism 40 can drive the picking box 41 to move, it can give the first material an initial speed when it is combined, so that the first material can come into contact with the second material in the conveying process while having an initial speed, thus completing the combination of the first material and the second material; wherein, the initial speed is a preset speed. In this embodiment, at the position where the first material and the second material are combined, the direction of the preset speed of the picking box 41 is the same as the conveying direction of the conveyor belt mechanism 30, and the magnitude of the preset speed is equal to the conveying speed of the conveyor belt mechanism 30.

[0090] In one implementation, the second material is a strip structure. After the first material is placed on the second material, the strip-shaped binding material needs to be cut to form an absorbent core.

[0091] In one implementation, the second material can be an independent sheet structure, allowing the first material, after being placed on top of the second material, to directly form an absorbent core. This implementation reduces waste of the second material compared to the previous implementation; therefore, this implementation will be used as an example in the following description.

[0092] In practical applications, if the first material is placed directly on the second material during transport before it has an initial velocity, it can easily cause misalignment between the two materials during bonding, affecting the bonding quality. To ensure bonding quality, if the first material does not have an initial velocity, the transport of the second material needs to be stopped during bonding, causing the conveyor belt mechanism to operate at 30 intervals. This results in reduced production efficiency and increased difficulty in production control.

[0093] The absorbent core bonding device provided in this embodiment can place the first material on the second material without stopping the conveyor belt mechanism 30. Since the first material and the second material with initial speed have a smaller degree of deviation or even no deviation, it can ensure the production speed while ensuring the bonding quality.

[0094] In practical applications, the absorber core assembly is equipped with a discharge mechanism for conveying the first material. This discharge mechanism can be, for example, a cutting mechanism 20. Specifically, the cutting mechanism 20 receives the strip and cuts it to form the first material. The first material can be an independent sheet structure, meaning the cutting mechanism 20 can cut the strip into multiple independent first materials. It should be noted that the cutting mechanism 20 can use existing cutting methods, such as pressing with a pressure knife, which will not be elaborated upon in this embodiment.

[0095] The transfer mechanism 40 is used to transfer the independent sheet-like first material to the second material. However, in practical applications, the feeding rate of the first material is affected by factors such as the cutting rate, which often results in the feeding rate of the first material and the transfer rate at which the transfer mechanism 40 transfers the first material out. Therefore, in this embodiment, the intermediate transfer mechanism 50 can play a role in transfer and buffering. On the one hand, it reduces the inconvenience of the transfer mechanism 40 directly obtaining the first material from the cutting mechanism 20, playing an intermediate rate matching and buffering role. On the other hand, it can extend the conveying path between the discharge mechanism and the transfer mechanism 40 to adapt to the complex site layout requirements in practical applications.

[0096] In one embodiment, the material picking box 41 and the material picking component 51 are fed by rotation. Specifically, the transfer mechanism 40 may be provided with a rotating structure such as a rotating wheel 46 capable of circumferential rotation; taking the rotating structure as the rotating wheel 46 as an example, the material picking box 41 is disposed on the rotating wheel 46; at the same time, the transfer mechanism 40 is provided with a drive mechanism such as a motor connected to the support component, so that when the drive mechanism is started, the rotating wheel 46 can drive the material picking box 41 to rotate circumferentially.

[0097] Similarly, the transfer mechanism 50 may include a rotatable turntable 52; the material picker 51 is disposed on the turntable 52. The turntable 52 is connected to a second drive mechanism such as a rotating motor, and when the second drive mechanism is started, the material picker 51 can be driven to rotate circumferentially through the turntable 52.

[0098] In this embodiment, the rotation path of the material picking component 51 is tangent to the rotation path of the material picking box 41.

[0099] In the above embodiments, the preset speed of the material picking box 41 being equal to the conveying speed of the conveyor belt mechanism 30 means that when the material picking box 41 transfers the first material to the second material being conveyed, the linear speed of the material picking box 41 is equal to and in the same direction as the conveying speed of the conveyor belt mechanism 30.

[0100] The linear velocity of the material picking box 41 can be controlled by controlling the output power of its drive mechanism. When the linear velocity of the material picking box 41 is equal to the conveying speed of the conveyor belt mechanism 30, the offset when the first material and the second material are combined can be further controlled, thereby further ensuring the combination quality.

[0101] In one embodiment, the conveyor belt mechanism 30 is capable of conveying the second material horizontally. The transfer mechanism 40 is positioned directly above the conveyor belt mechanism 30. When the pick-up box 41 rotates to a position directly below the transfer mechanism 40, it can transfer the first material onto the second material; therefore, the position directly below the transfer mechanism 40 is the junction point between the pick-up box 41 and the conveyor belt mechanism 30. Simultaneously, when the pick-up box 41 rotates to this position directly below the transfer mechanism 40, its linear velocity is horizontal, parallel to the conveying direction of the conveyor belt mechanism 30, and equal to the conveying speed of the conveyor belt mechanism 30.

[0102] In other embodiments, the second material can be combined with the first material during the conveying process by setting up several robotic arms as a transfer mechanism 40 and a transit mechanism 50. Specifically, taking one robotic arm as both a transfer mechanism 40 and a transit mechanism 50 as an example, the implementation can be as follows: the robotic arm moves to the discharge port of the cutting mechanism 20 to obtain the first material, and then drives the first material to be transferred above the conveyor belt mechanism 30, and drives the first material to move along the conveying direction of the second material. During the movement of the first material, the first material is placed on the second material, so that the first material can be combined with the second material while having an initial speed, thus avoiding the situation where the conveying of the second material stops.

[0103] In this application, the embodiment of rotating conveying with transfer mechanism 40 and intermediate mechanism 50 is different from the embodiment of conveying with a robotic arm. The former does not require a robotic arm with complex transmission, but only a rotatable picking box 41. The structure required for its implementation can be simplified, thereby reducing the construction cost and control difficulty of the device.

[0104] Meanwhile, in practical applications, due to limitations in the installation space and the structure of the equipment itself, the transfer mechanism 40 often cannot be directly positioned between the conveyor belt mechanism 30 and the cutting mechanism 20, and simultaneously tangential to the discharge ports of both the conveyor belt mechanism 30 and the cutting mechanism 20. In this embodiment, the intermediate transfer mechanism 50 serves as an intermediate transport mechanism. Figure 1 As shown, the rotation path of the picking box 41 is tangent to the rotation path of the picking component 51, and their rotation directions are opposite. Thus, the transfer mechanism 50 can extend the transfer path and change the feeding direction of the transfer mechanism 40, ensuring that the final transfer mechanism 40 can feed materials along the conveying direction of the conveyor belt mechanism 30.

[0105] It should be noted that, in practical applications, the number of transfer mechanisms 50 can be set according to actual needs, specifically so that the transfer mechanism 50 can transfer the first material on the cutting mechanism 20 to the transfer mechanism 40.

[0106] In the embodiments provided in this application, the first material and the second material can be, for example, different structural layers in the absorbent layer of an absorbent article. After the first material and the second material are combined, a multi-layer absorbent layer can be formed. When the absorbent layer has multiple layers, multiple transfer mechanisms 40 can be provided. For example, in the manufacturing process of an absorbent layer including a three-layer structure, the combined absorbent core can be transferred to the third material in the conveying process by a second transfer mechanism 40. The combination of other layer structures is similar and will not be described in detail in this embodiment.

[0107] In other embodiments, the first material and the second material can be, for example, the absorbent layer and the base layer in an absorbent article. The base layer can be, for example, a waterproof layer. That is, the transfer mechanism 40 can transfer the absorbent layer onto the base layer, achieving a bond between the absorbent layer and the base layer.

[0108] In one implementation, the receiving position of the material picker 51 for acquiring the first material can be located at the discharge port of the cutting mechanism 20. That is, in this embodiment, the rotation path of the material picker 51 is tangent to the discharge port of the cutting mechanism 20, so that the material picker 51 can move to the position of the discharge port to directly acquire the first material.

[0109] It should be noted that, in this embodiment, the combination of the first material and the second material refers to placing the first material on top of the second material so that the first material and the second material come into contact with each other.

[0110] In other embodiments, after the first and second materials are combined, they can be pressed or hot-pressed by a pressing mechanism. Specifically, the absorbent core bonding device in this embodiment includes a pressing mechanism; the pressing mechanism can be located at the next station after the first and second materials are combined. After the first and second materials are combined, they are conveyed to the pressing mechanism, which makes the combination of the first and second materials more stable.

[0111] As one implementation, the absorbent core bonding device may also include an unwinding mechanism 10 and a cutting mechanism 20.

[0112] The unwinding mechanism 10 is used to unwind the material strip, and it may include a main material roll 11 with the material strip wound on it and a drive device. The drive device can drive the main material roll 11 to rotate, so that the material strip is released at a uniform speed according to the production speed. After being supported by multiple support rollers, the unwound material strip reaches the cutting mechanism 20.

[0113] In one embodiment, the absorbent core bonding device includes: an adhesive application mechanism 70; the adhesive application mechanism 70 is disposed on the conveyor belt mechanism 30 and is used to apply adhesive to the second material so that the first material adheres to the second material after contacting it.

[0114] In this embodiment, the adhesive application mechanism 70 can apply adhesive to the second material by spraying, wiping, or other methods, specifically by applying it to the upper surface of the second material. The adhesive can be, for example, medical adhesive. After the first material is placed between the first material and the second material in the dispensing box 41, since the adhesive is liquid, it will spread out across the cross-section between the first and second materials to fill the tiny gaps between them, thus achieving the bonding of the first and second materials.

[0115] In one embodiment, when the picking box 41 picks up the first material, the linear velocity of the picking box 41 is equal to the linear velocity of the picking component 51, which can ensure the accuracy and stability of material handling by the picking box 41 and the picking component 51.

[0116] As a further improvement, the transfer mechanism 40 includes a speed change component; the speed change component is connected to the rotating wheel 46, so that the speed change component can drive the rotating wheel 46 and the material box 41 to rotate at different speeds.

[0117] In practical applications, the cutting mechanism 20 needs to cut the material strip, so its output speed will inevitably be mismatched with the conveying speed of the conveyor belt mechanism 30. In this embodiment, the material pick-up box 41 is configured with a variable speed rotation structure, so that it can simultaneously adapt to the output speed of the cutting mechanism 20 and the conveying speed of the conveyor belt mechanism 30.

[0118] In one implementation, the drive mechanism for rotating the material picking box 41 is a variable frequency motor. Specifically, the speed change component includes a variable frequency motor mounted on the transfer mechanism 40, which can drive the material picking box 41 to rotate at a variable speed by means of frequency conversion. The process of the variable frequency motor driving the component to rotate at a variable speed is prior art, and therefore will not be described in detail in this embodiment.

[0119] In one embodiment provided in this application, please refer to Figure 2 The transmission assembly includes a support member 47, a drive shaft 42, and a driven shaft 43. The support member 47 can be a support frame or housing structure for mounting the drive shaft 42 and the driven shaft 43. A first eccentric gear 44 is provided on the drive shaft 42; the axis of the first eccentric gear 44 is eccentrically positioned to the axis of the drive shaft 42. A rotating wheel 46 is provided on the driven shaft 43.

[0120] A second eccentric gear 45 is provided on the driven shaft 43; the axis of the second eccentric gear 45 is eccentrically positioned to the driven shaft 43. The first eccentric gear 44 is meshed with the second eccentric gear 45.

[0121] The drive shaft 42 can be connected to a drive driver, which can be, for example, a motor. When the drive driver is started, it can drive the drive shaft 42 to rotate, thereby sequentially driving the first eccentric gear 44, the second eccentric gear 45, the driven shaft 43, and the rotating wheel 46 to rotate.

[0122] In this embodiment, the first eccentric gear 44 and the second eccentric gear 45 are configured to maintain a continuously meshed state during rotation. Due to the eccentric effect of the first eccentric gear 44 and the second eccentric gear 45, the second eccentric gear 45 will accelerate or decelerate as the rotation radius of the first eccentric gear 44 changes during rotation. Specifically, as the radius from the drive shaft 42 to the meshing point gradually increases, the second eccentric gear 45 drives the rotating wheel 46 to perform an accelerating motion with a gradually increasing angular velocity; as the radius from the drive shaft 42 to the meshing point gradually decreases, the second eccentric gear 45 drives the rotating wheel 46 to perform a decelerating motion with a gradually increasing angular velocity. Therefore, the transmission components on the transfer mechanism 40 can drive the material handling box 41 to perform a variable speed motion with changing linear velocity.

[0123] In practical applications, the correspondence between the acceleration and deceleration processes of the material picking box 41 and the conveyor belt mechanism 30 can be determined according to the actual production speed. The speed change rate and docking line speed of the material picking box 41 can also be determined by technicians according to the actual production speed. Therefore, in this embodiment, no specific restrictions are placed on the dimensions of each component in the transfer mechanism 40.

[0124] Taking the cutting speed of the cutting mechanism 20 as less than the conveying speed of the conveyor belt mechanism 30 as an example, the transfer mechanism 50 maintains a constant rotation speed during the material transfer process. Therefore, the linear speed of the picking component 51 on the transfer mechanism 50 is less than the conveying speed of the conveyor belt mechanism 30. Correspondingly, in this embodiment, the rotation process of the picking box 41 from the docking point of the conveyor belt mechanism 30 to the docking point of the transfer mechanism 50 is a deceleration motion; the rotation process of the picking box 41 from the docking point of the transfer mechanism 50 to the docking point of the conveyor belt mechanism 30 is an acceleration motion.

[0125] In this embodiment, the material cut by the cutting mechanism 20 can be directly transferred to the conveyor belt mechanism 30 by the transfer mechanism 50 and the transfer mechanism 40 without the need for a temporary storage mechanism or other buffer mechanism, thereby reducing the number of transfers, reducing the complexity of the device and improving production efficiency.

[0126] In one implementation, the material picking box 41 is a negative pressure suction box, which enables it to acquire or transfer the first material through negative pressure adsorption. Correspondingly, the transfer mechanism 40 is provided with a suction pipe connected to the material picking box 41, so that the material picking box 41 can be controlled to pick up and release material through the negative pressure chamber connected to the suction pipe.

[0127] In one implementation, the material handling component 51 is a negative pressure suction component. Correspondingly, the transfer mechanism 50 is provided with a second suction pipe connected to the material handling component 51, so that the material handling component 51 can be controlled to pick up and release materials through the second negative pressure chamber connected to the second suction pipe.

[0128] It should be noted that the method of controlling the material handling structure such as the material handling box 41 or the material handling component 51 through the negative pressure chamber to draw air or break the vacuum is existing technology, so its specific control process will not be described in detail in this embodiment.

[0129] In one embodiment provided in this application, please refer to Figure 3 The cutting mechanism 20 includes a main body 21, a receiving roller 22, and a pressure roller 23. The receiving roller 22 and the pressure roller 23 are rotatably mounted on the main body 21. In this embodiment, the pressure roller 23 is positioned directly above the receiving roller 22. A cutting area is formed between the receiving roller 22 and the pressure roller 23 through which the feed strip passes. The receiving roller 22 supports the feed strip; the outer circumferential surface of the pressure roller 23 is provided with a plurality of pressure blade structures; the pressure blade structures are used to cut the feed strip in the cutting area to form a first material of a preset shape. The number of pressure blade structures can be set according to the actual application.

[0130] Specifically, as the material strip passes through the cutting zone, the rotating receiving roller 22, in conjunction with the rotating cutting roller 23, cuts the material strip, causing the first material to be cut off from the strip. The linear rotational speeds of the receiving roller 22 and the cutting roller 23 are configured to be equal to the conveying speed of the material strip. In practical applications, the cutting structure is configured to abut against the receiving roller 22, ensuring that the material strip passing through the cutting zone can have the first material cut off and separated from the strip.

[0131] The remaining portion of the strip after the first material is separated can be removed by the waste suction component 26 through suction. Therefore, a waste suction component 26 facing the cutting area can be provided on the main body 21 of the mechanism.

[0132] The first material, after being cut out, is further conveyed along the rotation direction as the receiving roller 22 rotates. In one embodiment, the receiving roller 22 may be provided with multiple negative pressure suction holes connected to a vacuum system; the multiple negative pressure suction holes are arranged in a structure adapted to the shape of the first material, so that the receiving roller 22 can temporarily adsorb the first material.

[0133] In the above-described embodiment with a transfer mechanism 50, the junction of the transfer mechanism 50 and the cutting mechanism 20 can be located on the side of the receiving roller 22 in the horizontal direction; specifically, the rotation path of the material taking part 51 is tangent to the side of the receiving roller 22 in the horizontal direction.

[0134] In some cases, the first material not only needs to be cut and separated from the conveyor belt, but also needs to be punched.

[0135] In one embodiment, the workstations for punching and cutting the first material can be set separately. For example, the cutting mechanism 20 is configured to include a first cutting mechanism and a second cutting mechanism. The first cutting mechanism is used to punch holes in the strip, and the second cutting mechanism is used to cut the punched area to form the first material and separate the first material from the strip.

[0136] In another embodiment, please refer to Figure 3 and Figure 4 The pressure knife structure includes a cutting edge pressure knife 24 and several perforated pressure knives 25; the cutting edge pressure knife 24 is annular and is used to separate materials of a preset shape from the material strip; the several perforated pressure knives 25 are arranged inside the cutting edge pressure knife 24 and are used to make holes in the core.

[0137] In this embodiment, both the cutting and drilling processes are integrated into the pressure knife structure, making the overall structure of the device more compact.

[0138] In practical applications, the pressure rollers 23 include several, and the pressure structures on each pressure roller 23 can be arranged in different ways. The pressure rollers 23 are detachably connected to the main body 21 of the mechanism, so that different pressure rollers 23 can be selected for different production needs.

[0139] In one embodiment, the pressure roller 23 includes a support shaft 231 and an outer ring 232; the outer ring 232 is rotatably sleeved on the support shaft 231; the pressure structure is disposed on the outer circumferential surface of the outer ring 232; the support shaft 231 is provided with an air intake chamber 233 and an air blowing chamber 234; the perforated pressure cutter 25 is provided with a vent hole 251 extending along its own axial direction, so that the perforated pressure cutter 25 forms an axially hollow structure; when the perforated pressure cutter 25 rotates to enter the pressure cutting area, the vent hole 251 connects to the air intake chamber 233; after the perforated pressure cutter 25 leaves the pressure cutting area, the vent hole 251 connects to the air blowing chamber 234. The outer ring 232 is a continuous frame structure, so that the part cut by the outer ring 232 can be completely separated from the material strip.

[0140] Specifically, the suction chamber 233 is connected to the negative pressure chamber, and the blowing chamber 234 is connected to the blowing chamber. When the vent 251 is connected to the suction chamber 233, the perforating knife 25 is in the suction state. At this time, after the perforating knife 25 opens the material strip, it can adsorb the residual material generated by the opening on the material strip. When the perforating knife 25 is connected to the blowing chamber 234, the vent 251 is in the blowing state. At this time, the residual material adsorbed on the perforating knife 25 is blown away, so that the residual material can be sucked away by the waste suction component 26.

[0141] As described above, in the embodiment where the pressure roller 23 is positioned above the receiving roller 22, the suction chamber 233 is positioned below the support shaft 231; and the blowing chamber 234 is positioned above the support shaft 231. Specifically, the perforating pressure knife 25 is connected to the suction chamber 233 during the process of perforating the material strip, and is connected to the blowing chamber 234 after the perforation is completed.

[0142] In one embodiment, the cutting mechanism 20 further includes a feed roller 27; the feed roller 27 is disposed on the main body 21 of the mechanism and located downstream of the cutting area, for winding up the strip after the first material has been separated.

[0143] In practical applications, after the pressure roller 23 cuts the strip, in addition to the circular scrap produced by the hole-opening process, the cutting and separation process will inevitably produce scrap as well.

[0144] In this embodiment, the cutting blade 24 is also configured to make the cut strip into a strip shape, that is, the surplus strip into a strip shape. The surplus strip is wound on the surplus roller 27 and is wound up by the rotation of the surplus roller 27.

[0145] In another embodiment provided in this application, please refer to Figure 1 The absorber core assembly also includes a storage mechanism 90; the storage mechanism 90 is located between the cutting mechanism 20 and the unwinding mechanism 10 and is used to store the material strip.

[0146] The method by which the material storage mechanism 90 stores the material strip is existing technology and will not be described in detail in this embodiment. The material storage mechanism 90 stores the material strip internally. The material strip released by the unwinding mechanism 10 is fed into and stored in the material storage mechanism 90. The material strip used by the cutting mechanism 20 is released from the material storage mechanism 90. When the unwinding mechanism 10 needs to replace the main material roll 11, the unwinding of the unwinding mechanism 10 can be paused, and then the material roll can be replaced. Due to the temporary storage effect of the material storage mechanism 90, the cutting mechanism 20 can continue to operate without interruption during the material replacement process, thereby ensuring the continuity of operation.

[0147] Correspondingly, the method of splicing the new material strip with the original material strip after changing the material strip roll is existing technology and will not be described in detail in this embodiment.

[0148] In one embodiment, the absorber core assembly further includes a correction mechanism 60; the correction mechanism 60 is disposed between the cutting mechanism 20 and the storage mechanism 90, and is used to correct the deviation of the material strip, thereby ensuring the tension of the material released from the storage mechanism 90.

[0149] In a more specific embodiment, the unwinding mechanism 10 includes a main roll 11 and a spare roll 12; both the main roll 11 and the spare roll 12 are wound with material strips. The spare roll 12 is located beside the main roll 11. The spare roll 12 provides the rate for changing the material strip. Correspondingly, after the main roll 11 is used up, the material strip on the spare roll 12 is activated, and a new material strip roll is loaded onto the main roll 11, then the material strip roll on the main roll 11 becomes the new spare material strip roll.

[0150] In one embodiment, the absorbent core bonding device further includes a quality inspection mechanism 80; the quality inspection mechanism 80 is disposed on the conveyor belt mechanism 30 and is used to detect whether the bonding effect of the first material and the second material meets the preset requirements.

[0151] In this embodiment, the quality inspection mechanism 80 is located downstream of the bonding point on the conveyor belt mechanism 30, where the bonding point is the point where the first material and the second material are bonded together. The quality inspection mechanism 80 can inspect the bonded materials through visual inspection or other methods to ensure the bonding effect of the first material and the second material.

[0152] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
