Description

Technical Field

[0001] This utility model relates to the field of sponge processing technology, specifically to an automatic pressing device for multi-layer sponges. Background Technology

[0002] The main component of most sponges is polyurethane, and different manufacturing processes result in different products. Sponges can be laminated for packaging, heat-processed, and burst-opened according to customer requirements. Polyurethane sponges themselves have many air bubbles, but their air permeability is not very high. It is necessary to evenly coat sponge blocks of different types and densities with glue and then laminate them together.

[0003] In current automated pressing equipment for multi-layer sponges, the lower sponge is usually coated with adhesive first, then the upper sponge is manually moved to the top of the lower sponge for pre-bonding, and then moved to the pressing device to press the upper and lower sponges together. However, manual operation involves many steps, consumes a lot of manpower and material resources, has a low degree of automation, and affects production efficiency. Utility Model Content

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

[0059] Please see Figure 1An embodiment of this utility model provides an automatic pressing device for multi-layer sponges, including: a sponge gluing device 10 for applying glue to the sponge, a sponge bonding conveying device 20 for conveying the sponge, a sponge bonding positioning device 30 for positioning the sponge, the sponge bonding positioning device 30 having a bonding positioning space 340 formed on the sponge bonding positioning device 30, a sponge pressing device for pressing the sponge, and a control device 50.

[0060] The sponge coating device 10, the sponge bonding and conveying device 20, the sponge bonding and positioning device 30, and the sponge pressing device are connected in sequence.

[0061] The sponge bonding and conveying device 20 includes a layered conveying mechanism 210 and an upper and lower layer conveying mechanism 220. The layered conveying mechanism 210 and the upper and lower layer conveying mechanism 220 are arranged between the sponge coating device 10 and the sponge bonding and positioning device 30. The layered conveying mechanism 210 and the upper and lower layer conveying mechanism 220 are arranged sequentially from the sponge coating device 10 to the sponge bonding and positioning device 30.

[0062] The layered conveying mechanism 210 includes a swing conveying assembly 211, a layered conveying support 212, and a swing drive assembly 213. The swing conveying assembly 211 is rotatably mounted on the layered conveying support 212. Under the drive of the swing drive assembly 213, the swing conveying assembly 211 swings upward to a first position and downward to a second position.

[0063] The upper and lower layer conveying mechanism 220 includes a lower layer conveying component 221, an upper layer conveying component 222, an upper layer translation drive component 223, and an inclined drive component 224. The upper layer conveying component 222 is disposed above the lower layer conveying component 221, and the upper layer translation drive component 223 is driven to the upper layer conveying component 222. The upper layer conveying component 222 moves back and forth along the conveying direction of the lower layer conveying component 221 under the drive of the upper layer translation drive component 223. The inclined drive component 224 is driven to the upper layer conveying component 222. The upper layer conveying component 222 rotates to the translation conveying position and the unloading position under the drive of the inclined drive component 224. When the upper layer conveying component 222 is in the unloading position, the conveying direction of the upper layer conveying component 222 gradually tilts downward along the conveying direction of the lower layer conveying component 221.

[0064] When the swing drive assembly 213 is in the first position and the upper conveying assembly 222 is in the translational conveying position, the upper conveying assembly 222 can move under the drive of the upper translational drive assembly 223 to the position where the conveying start end of the upper conveying assembly 222 is connected to the conveying end end of the swing conveying assembly 211 and move above the adhesive positioning space 340.

[0065] When the swing drive assembly 213 is in the second position, the starting end of the lower conveying assembly 221 is connected to the ending end of the swing conveying assembly 211.

[0066] The working principle of the automatic pressing device for multi-layer sponges in one embodiment of this utility model is described below:

[0067] Please see Figures 2 to 4 The lower sponge 240 is first coated with glue by the sponge coating device 10. After the lower sponge 240 is coated with glue, it is conveyed to the swing conveyor assembly 211. The swing drive assembly 213 drives the swing conveyor assembly 211 to rotate to the second position. The swing conveyor assembly 211 conveys the lower sponge 240 to the lower layer conveyor assembly 221. The lower layer conveyor assembly 221 conveys the lower sponge 240 to the sponge bonding and positioning device 30. The sponge bonding and positioning device 30 positions the lower sponge 240 in the bonding and positioning space 340.

[0068] Next, the upper sponge 230 is conveyed to the oscillating conveyor assembly 211. The oscillating drive assembly 213 drives the oscillating conveyor assembly 211 to rotate to the first position. The tilting drive assembly 224 drives the upper conveyor assembly 222 to rotate to the translational conveying position. The upper translational drive assembly 223 moves the upper conveyor assembly 222 toward the oscillating drive assembly 213, so that the conveying start end of the upper conveyor assembly 222 is connected to the conveying end end of the oscillating conveyor assembly 211. Subsequently, the oscillating conveyor assembly 211 conveys the upper sponge 230 to the upper conveyor assembly 222, and the upper translational drive assembly 223 moves the upper sponge 230 conveyor assembly 121 to the bonding position. Above the positioning space 340, the tilting drive component 224 drives the upper conveying component 222 to rotate to the unloading position. The upper conveying component 222 then conveys the upper sponge 230 towards the lower sponge 240 located in the bonding positioning space 340. Because the upper conveying component 222 is tilted, the foremost part of the upper sponge 230 will first contact the lower sponge 240. After the upper sponge 230 contacts the lower sponge 240, the upper translation drive component can gradually move towards the swing drive component 213, allowing the upper sponge 230 to be gradually conveyed onto the lower sponge 240, thus achieving a stable and accurate placement of the upper sponge 230 onto the lower sponge 240. The composite sponge formed by the upper sponge 230 and lower sponge 240 is then conveyed to the sponge pressing device, where the sponge pressing device presses the composite sponge together, tightly bonding the upper sponge 230 and lower sponge 240, thus achieving the composite of the upper sponge 230 and lower sponge 240.

[0069] If the upper sponge 230 cannot be accurately aligned with the lower sponge 240, the upper sponge 230 can be guided manually or by other mechanical equipment before it comes into contact with the lower sponge 240, so that the upper sponge 230 can accurately enter the adhesive positioning space 340 and align with the lower sponge 240.

[0070] Of course, depending on actual needs, three-layer and four-layer composite sponges can also be processed. The principle is similar to that described above. For the conveying and gluing of sponges other than the top layer, the conveying and gluing method of sponge 240 can be referenced.

[0071] In some optional embodiments, the upper and lower layer conveying mechanism 220 includes an upper layer translation bracket 225, which is movably disposed on the side of the upper layer conveying component 222. An upper layer translation drive component 223 is drivenly connected to the upper layer translation bracket 225 to achieve a drive connection between the upper layer translation drive component 223 and the upper layer conveying component 222. The upper layer conveying component 222 is rotatably disposed on the upper layer translation bracket 225. An tilt drive component 224 is assembled with the upper layer translation bracket 225. The upper layer translation drive component 223 drives the upper layer translation bracket 225 to translate, thereby indirectly driving the upper layer conveying component 222 to move. The tilt drive component 224 is directly drivenly connected to the upper layer conveying component 222.

[0072] In some optional embodiments, the upper and lower layer conveying mechanism 220 includes two upper layer translation brackets 225, which are respectively disposed on both sides of the upper layer conveying component 222. The two sides of the upper layer conveying component 222 are rotatably engaged with the two upper layer translation brackets 225, thereby improving the support stability of the upper layer conveying component 222 and preventing the upper layer conveying component 222 from being too wide and causing unstable tipping.

[0073] In some alternative implementations, the upper translation drive assembly 223 is driven to connect with two upper translation supports 225, and the two upper translation supports 225 move synchronously under the drive of the upper translation drive assembly 223.

[0074] The specific structure of the upper translation drive assembly 223 can be selected according to actual needs. The upper translation drive assembly 223 can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc., and is not limited to this example. In this embodiment, the upper translation drive assembly 223 includes an intermediate shaft 2231, two synchronous belt modules 2232, and an upper translation drive motor 2233. The upper translation drive motor 2233 is driven to drive the intermediate shaft 2231. The two ends of the intermediate shaft 2231 are driven to drive the two synchronous belt modules 2232 respectively. The synchronous belt modules 2232 are driven to drive the upper translation bracket 225. The upper translation drive motor 2233 drives the intermediate shaft 2231 to rotate, and the intermediate shaft 2231 drives the upper translation bracket 225 to move through the synchronous belt modules 2232.

[0075] In some alternative embodiments, a bearing 2251 is provided on the upper translation support 225, and the upper translation support 225 is rotatably engaged with the upper and lower conveying mechanisms 220.

[0076] The specific structures of the swing drive assembly 213 and the tilt drive assembly 224 can be selected according to actual needs. For example, in some optional embodiments, the swing drive assembly 213 and / or the tilt drive assembly 224 can be cylinders, electric cylinders, or hydraulic cylinders, and this is not limited to this example. In this embodiment, the swing drive assembly 213 has two cylinders, and the tilt drive assembly 224 has two cylinders. The two cylinders of the swing drive assembly 213 are respectively arranged on both sides of the layered conveying bracket 212, and the output shaft of the cylinder of the swing drive assembly 213 is connected to the swing conveying assembly 211. The two cylinders of the tilt drive assembly 224 are respectively arranged on two upper translation brackets 225, and the output shaft of the cylinder of the tilt drive assembly 224 is connected to the upper conveying assembly 222.

[0077] In some optional embodiments, the side of the lower translation drive assembly is provided with an upper translation guide rail 2211 extending along the conveying direction of the lower conveying assembly 221. The upper translation bracket 225 slides with the upper translation guide rail 2211, thereby improving the movement stability of the upper translation bracket 225. In this embodiment, the upper translation guide rail 2211 is provided on both sides of the lower translation drive assembly.

[0078] The specific structures of the upper conveyor assembly 222, the oscillating conveyor assembly 211, and the lower conveyor assembly 221 can be selected according to actual needs, such as mesh belt conveyor assembly, roller conveyor assembly, chain conveyor assembly, and belt conveyor assembly. In this embodiment, the upper conveyor assembly 222, the oscillating conveyor assembly 211, and the lower conveyor assembly 221 all adopt belt conveyor assemblies.

[0079] Please see Figure 5 In some optional embodiments, the layered conveying support 212 is provided with a plurality of buffer pads 214. When the swing conveying component 211 swings downward to the second position under the drive of the swing driving component 213, the swing conveying component 211 abuts against the buffer pads 214. The buffer pads 214 can provide a buffering function for the swing conveying component 211 to avoid damage to the swing conveying component 211 due to long-term collision.

[0080] Please see Figures 6 to 8 The specific structure of the sponge coating device 10 can be selected according to actual needs. For example, the sponge coating device 10 includes a correction mechanism 110 and a coating mechanism 120.

[0081] The correction mechanism 110 is used to correct the position of the sponge relative to the feeding conveyor assembly 111. The correction mechanism 110 includes the feeding conveyor assembly 111, two correction plates 112 and a correction drive assembly 113. The two correction plates 112 are respectively arranged on both sides of the feeding conveyor assembly 111. The correction drive assembly 113 is drivenly connected to the correction plates 112. The two correction plates 112 move closer to each other and further away from each other under the drive of the correction drive assembly 113.

[0082] The glue application mechanism 120 includes a sponge conveying assembly 121, a glue application lifting assembly 122, a glue application translation assembly 123, and multiple glue nozzles 124. The sponge conveying assembly 121 is located at the end of the feeding conveying assembly 111, and the glue nozzles 124 are located above the sponge conveying assembly 121. The glue application lifting assembly 122 is driven to the glue nozzles 124, and the glue nozzles 124 are lifted and lowered relative to the sponge conveying assembly 121 under the drive of the glue application lifting assembly 122. The glue application translation assembly 123 is driven to the glue nozzles 124, and the glue nozzles 124 move relative to the sponge conveying assembly 121 in the glue application direction under the drive of the glue application translation assembly 123. The glue application direction is not parallel to the conveying direction of the sponge conveying assembly 121.

[0083] The working principle of the sponge adhesive applicator 10 in one embodiment of this utility model is explained below:

[0084] After the sponge is placed in the feeding conveyor assembly 111, the correction drive assembly 113 drives the two correction plates 112 to move closer together, so that the sponge is clamped and positioned by the two correction plates 112. Then, the correction drive assembly 113 drives the two correction plates 112 to move away from each other, and then the feeding conveyor assembly 111 can transport the sponge to the sponge conveying assembly 121. Of course, after the two correction plates 112 clamp and position the sponge, the two correction plates 112 may not move away from each other or may only move slightly away from each other. During the process of the feeding conveyor assembly 111 transporting the sponge to the sponge conveying assembly 121, the correction plates 112 can guide the sponge, making the position of the sponge more accurate.

[0085] When at least a portion of the sponge reaches the sponge conveying assembly 121, the adhesive application lifting assembly 122 lowers the adhesive nozzle 124, bringing it closer to the sponge. Driven by the adhesive application translation assembly 123, the adhesive nozzle 124 moves in the adhesive application direction. Combined with the movement of the sponge driven by the sponge conveying assembly 121, the adhesive is sprayed along a suitable path. In this embodiment, the adhesive application direction is perpendicular to the conveying direction of the sponge conveying assembly 121. The adhesive nozzle 124 can spray adhesive back and forth onto the sponge in the adhesive application direction, while the sponge conveying assembly 121 gradually moves the sponge, achieving uniform adhesive application to the sponge.

[0086] By correcting the position of the sponge through the correction mechanism 110, the position of the glue nozzle 124 can be relatively accurate when the sponge is transported to the sponge transport assembly 121, so that the glue nozzle 124 can accurately spray the glue onto the sponge.

[0087] The conveying end of the sponge conveying assembly 121 is connected to the conveying beginning of the oscillating conveying assembly 211. The lower sponge 240 after being coated with adhesive is conveyed to the oscillating conveying assembly 211 through the sponge conveying assembly 121.

[0088] The correction drive assembly 113 can synchronously drive the two correction plates 112 to translate, or it can drive the two correction plates 112 to translate separately. Its specific structure can be selected according to actual needs. The correction drive assembly 113 can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc., and is not limited to this example. For example, the correction drive assembly 113 includes two correction electric cylinders, which are correspondingly connected to the correction plates 112 for driving.

[0089] The way the glue application translation component 123 and the glue application lifting component 122 drive the glue nozzle 124 to move can be selected according to actual needs. For example, the glue application translation component 123 is driven to connect with the glue application lifting component 122, driving the glue application lifting component 122 and the glue nozzle 124 to move together, thereby indirectly driving the glue nozzle 124 to move. The glue application lifting component 122 directly drives the glue nozzle 124 to move. In some optional embodiments, the glue application mechanism 120 also includes a glue application lifting frame 125, which is movably arranged above the sponge conveying component 121. The glue application lifting component 122 is driven to connect with the glue application lifting frame 125, and multiple glue nozzles 124 are movably arranged on the glue application lifting frame 125, and are respectively located on the front and rear sides of the glue application lifting frame 125 in the conveying direction of the sponge conveying component 121. The glue application lifting assembly 122 drives the glue application lifting frame 125 to rise and fall, thereby driving the glue application translation assembly 123 and the glue nozzle 124 to rise and fall together, thus indirectly driving the glue nozzle 124 to move. Increasing the number of colloid nozzles 124 can speed up the efficiency of applying colloid to the sponge. However, a large number of colloid nozzles 124 can lead to a narrow range of movement for the colloid nozzles 124, affecting the design requirements of the adhesive path. Moreover, adjacent colloid nozzles 124 need to maintain a distance from each other in the adhesive application direction to avoid collisions, which sometimes results in adhesive gaps on the sponge between adjacent colloid nozzles 124. Distributing the colloid nozzles 124 on the front and rear sides of the adhesive application lifting frame 125 can increase the number of colloid nozzles 124. At the same time, the colloid nozzles 124 located on the front side of the adhesive application lifting frame 125 and the colloid nozzles 124 located on the rear side of the adhesive application lifting frame 125 do not need to consider the spacing between them. This can avoid the situation where adjacent colloid nozzles 124 need to be spaced apart in the adhesive application direction, resulting in adhesive gaps on the sponge.

[0090] Please see Figure 9The structure of the adhesive application translation component 123 can be selected according to actual needs. For example, in some optional embodiments, the adhesive application translation component 123 includes multiple adhesive application translation seats 1231, multiple adhesive application translation motors 1232, and multiple translation transmission gears 1233. The multiple adhesive application translation seats 1231 are respectively movably arranged on the front and rear sides of the lifting frame. The adhesive application translation motors 1232 are correspondingly arranged on the adhesive application translation seats 1231 and are correspondingly driven and connected to the translation transmission gears 1233. The colloid nozzles 124 are correspondingly installed on the adhesive application translation seats 1231. The adhesive application lifting frame 125 is provided with translation transmission racks 1234 on the front and rear sides of the sponge conveying component 121 in the conveying direction. The adhesive application translation seats 1231 located on the same side of the adhesive application lifting frame 125 are arranged sequentially along the translation transmission racks 1234. The translation transmission gears 1233 mesh with the translation transmission racks 1234. The translation transmission gear 1233 on the glue application translation seat 1231 located on the front side of the glue application lifting frame 125 meshes with the translation transmission rack 1234 located on the front side of the glue application lifting frame 125, while the translation transmission gear 1233 on the glue application translation seat 1231 located on the rear side of the glue application lifting frame 125 meshes with the translation transmission rack 1234 located on the rear side of the glue application lifting frame 125. The glue application translation motor 1232 drives the translation transmission gear 1233 to rotate, causing the translation transmission gear 1233 to move relative to the translation transmission rack 1234. This, in turn, drives the glue application translation seat 1231 to move along the translation transmission rack 1234, thereby moving the glue nozzle 124 located on the glue application translation seat 1231. Each glue application translation seat 1231 can move independently, thus individually driving each glue nozzle 124 to achieve a wider range of glue application paths. Moreover, the glue application translation seats 1231 located on the same side of the glue application lifting frame 125 share the same translation transmission rack 1234, which helps to simplify the structure. In addition, the cooperation between the translation transmission gear 1233 and the translation transmission rack 1234 can improve the accuracy of the movement of the glue nozzle 124. In this embodiment, the front and rear sides of the glue application lifting frame 125 are also provided with support guide rails extending along the glue application direction, and the glue application translation seat 1231 slides with the support guide rails, thereby improving the movement stability of the glue application translation seat 1231.

[0091] Please see Figure 10In some optional embodiments, the adhesive application lifting assembly 122 includes an adhesive application fixing bracket 1221, a lifting transmission rack 1222, an adhesive application lifting motor 1223, and a lifting transmission gear 1224. The adhesive application fixing bracket 1221 is disposed on the side of the sponge conveying assembly 121, the lifting transmission rack 1222 is disposed on the adhesive application fixing bracket 1221, and the adhesive application lifting motor 1223 is disposed on the lifting frame and drivenly connected to the lifting transmission gear 1224. The lifting transmission gear 1224 meshes with the lifting transmission rack 1222. The adhesive application lifting motor 1223 drives the lifting transmission gear 1224 to rotate, causing the lifting transmission gear 1224 to move along the lifting transmission rack 1222, thereby driving the adhesive application lifting frame 125 to rise and fall, thus achieving stable lifting and falling of the adhesive nozzle 124. The cooperation between the lifting transmission gear 1224 and the lifting transmission rack 1222 can improve the accuracy of the lifting and falling of the adhesive nozzle 124.

[0092] In some optional embodiments, the adhesive application lifting assembly 122 includes an intermediate drive shaft 1225, two adhesive application fixing brackets 1221, two lifting drive racks 1222, and two lifting drive gears 1224. The two adhesive application fixing brackets 1221 are respectively disposed on both sides of the sponge conveying assembly 121, the adhesive application lifting frame 125 is located between the two adhesive application fixing brackets 1221, the lifting drive racks 1222 are correspondingly disposed on the adhesive application fixing brackets 1221, the intermediate drive shaft 1225 is rotatably mounted on the lifting frame and is located between the two adhesive application fixing brackets 1221, and the two lifting drive gears 1224 are assembled... The glue application lifting motor 1223 is connected to the intermediate drive shaft 1225 and meshes with two lifting drive racks 1222. The glue application lifting frame 125 is supported by two glue application fixing brackets 1221. The intermediate drive shaft 1225 drives the two lifting drive gears 1224 to rotate, which in turn drives the lifting drive gears 1224 to rise and fall along the lifting drive racks 1222. Since the power of the two lifting drive gears 1224 is applied to the glue application lifting frame 125, the stability of the glue application lifting frame 125 is improved, and the wobbling of the glue application lifting frame 125 is avoided.

[0093] In some optional embodiments, the glue-applying fixing bracket 1221 is provided with a plurality of lifting guide rails 1226, and the glue-applying lifting frame 125 slides in cooperation with the lifting guide rails 1226, which helps to improve the lifting stability of the glue-applying lifting frame 125.

[0094] Please see Figures 11 to 12In some optional embodiments, the feeding and conveying assembly 111 includes a feeding bracket 1111, a feeding drive module 1112, multiple feeding conveying rollers 1113, and multiple correction and guiding structures 1114. The multiple feeding conveying rollers 1113 are rotatably mounted on the feeding bracket 1111 and arranged sequentially in the direction close to the sponge conveying assembly 121. The feeding drive module 1112 is drivenly connected to the feeding conveying rollers 1113. The correction and guiding structures 1114 are disposed between adjacent feeding conveying rollers 1113. The system includes multiple guide wheels 11141, which are rotatably mounted on the feeding bracket 1111 and arranged sequentially along the axial direction of the feeding conveyor roller 1113. Two correction plates 112, driven by the correction drive assembly 113, move closer to and further away from each other along the axial direction of the feeding conveyor roller 1113. When the correction plates 112 move to move the sponge, the sponge will drive the guide wheels 11141 to rotate. Rolling friction exists between the sponge and the guide wheels 11141, which helps guide the movement of the sponge and avoids scratching. The feeding drive module 1112 can be a feeding drive motor, which is connected to the multiple feeding conveyor rollers 1113 to drive their rotation; however, this example is not limited to this one.

[0095] Please see Figures 13 to 14 The specific structure of the sponge bonding and positioning device 30 can be selected according to actual needs. For example, the sponge bonding and positioning device 30 includes: a positioning and conveying component 310, a left and right positioning mechanism 320 and a front and rear positioning mechanism 330.

[0096] The left and right positioning mechanism 320 includes two side positioning members 321 and a side positioning drive assembly 322. The two side positioning members 321 are disposed on both sides of the positioning and conveying assembly 310. The side positioning drive assembly 322 is driven to connect with the side positioning members 321. The two side positioning members 321 move closer to each other or further away from each other under the drive of the side positioning drive assembly 322.

[0097] The front and rear positioning mechanism 330 includes a rear positioning member 331, a front positioning member 332, a positioning lifting assembly 333, and a rear positioning moving assembly 334. The rear positioning member 331 and the front positioning member 332 are arranged sequentially along the conveying direction of the positioning conveying assembly 310. The positioning lifting assembly 333 is driven to connect with the front positioning member 332 and the rear positioning member 331. The front positioning member 332 and the rear positioning member 331 are lifted and lowered relative to the positioning conveying assembly 310 under the drive of the positioning lifting assembly 333. The rear positioning moving assembly 334 is driven to connect with the rear positioning member 331. The rear positioning member 331 moves in the direction of approaching and moving away from the front positioning member 332 under the drive of the rear positioning moving assembly 334.

[0098] The rear positioning member 331, the front positioning member 332, and the two side positioning members 321 can surround each other to form an adhesive positioning space 340 after movement.

[0099] The starting end of the positioning conveying component 310 is connected to the ending end of the lower conveying component 221. The lower sponge 240 is conveyed to the positioning conveying component 310 through the lower conveying component 221. The ending end of the positioning conveying component 310 is connected to the sponge pressing device. The initially bonded upper sponge 230 and lower sponge 240 are conveyed to the sponge pressing device through the positioning conveying component 310 for pressing.

[0100] The working principle of the sponge bonding and positioning device 30 according to one embodiment of the present invention is explained below:

[0101] Please see Figure 15 The lower sponge 240 moves onto the positioning and conveying assembly 310 and is conveyed by the positioning and conveying assembly 310 until the lower sponge 240 abuts against the front positioning member 332. The two side positioning members 321 move closer to each other under the drive of the side positioning drive assembly 322 until the side positioning members 321 abut against the side of the sponge. The rear positioning member 331 also moves towards the sponge under the drive of the rear positioning moving assembly 334 until the rear positioning member 331 abuts against the rear side of the sponge. Thus, the positioning of the four sides of the sponge is achieved. Then the upper sponge 230 can be moved onto the lower sponge 240 for preliminary bonding, which improves the bonding accuracy of the upper sponge 230 and the lower sponge 240.

[0102] In some optional embodiments, a sponge positioning portion 3211 is provided on the side positioning member 321 and / or the rear positioning member 331 and / or the front positioning member 332. The sponge positioning portion 3211 extends along the edge of the adhesive positioning space 340 and conforms to the side of the sponge, which helps to improve the accuracy of sponge positioning. In this embodiment, sponge positioning portions 3211 are provided on the side positioning member 321, the rear positioning member 331, and the front positioning member 332.

[0103] In some optional embodiments, an auxiliary support plate 311 is provided on at least one side of the positioning and conveying assembly 310. The auxiliary support plate 311 extends outward from the side of the positioning and conveying assembly 310 away from the positioning and conveying assembly 310. At least a portion of the auxiliary support plate 311 is located at the bottom of the adhesive positioning space 340 to assist in supporting the sponge. When the sponge is wide, the left and right sides of the sponge may extend to the outside of the positioning and conveying assembly 310. Therefore, when the upper sponge 230 is placed on the lower sponge 240, the side of the lower sponge 240 may bend downward due to gravity, which may cause part of the lower sponge 240 to be unable to fit with the upper sponge 230. The lower sponge 240 is supported by the auxiliary support plate 311, thereby avoiding the bending phenomenon of the lower sponge 240.

[0104] In some optional embodiments, the auxiliary support plate 311 is connected to a support drive assembly 312. The auxiliary support plate 311 moves to a retracted position and an extended position under the drive of the support drive assembly 312. When the auxiliary support plate 311 is in the retracted position, the auxiliary support plate is disengaged from the bottom of the adhesive positioning space 340, thereby avoiding the auxiliary support plate from affecting or hindering the operation of other mechanisms or from hindering the workers from performing auxiliary work. When the auxiliary support plate 311 is in the extended position, at least a portion of the auxiliary support plate 311 is at the bottom of the adhesive positioning space 340, thereby providing support for the sponge.

[0105] The specific method by which the support drive assembly 312 drives the auxiliary support plate 311 can be selected according to actual needs. For example, in some optional embodiments, the auxiliary support plate 311 can be flipped and arranged on the side of the positioning and conveying assembly 310. When the auxiliary support plate 311 is in the unfolded position, the support drive assembly 312 drives the auxiliary support plate 311 to flip downwards so that the auxiliary support plate 311 moves to the retracted position. At this time, the auxiliary support plate 311 is below the bonding and positioning space 340. When the support drive assembly 312 needs to move to the unfolded position, it drives the auxiliary support plate 311 to flip upwards to the bottom of the bonding and positioning space 340. The support drive assembly 312 can be a support drive motor, which drives the auxiliary support plate 311 to rotate. Alternatively, the support drive motor can also be a telescopic drive assembly such as a cylinder or electric cylinder, with the output shaft of the support drive motor rotating in conjunction with the auxiliary support plate 311. By pulling / pushing the auxiliary support plate 311, the auxiliary support plate 311 can be rotated.

[0106] Of course, the auxiliary support plate 311 can also be retracted or extended in other ways. For example, the auxiliary support plate 311 can also be moved between the extended position and the retracted position by translation. In one embodiment, the auxiliary support plate 311 moves toward the side of the positioning and conveying assembly 310 under the drive of the support drive assembly 312, so that when the auxiliary support plate 311 is in the retracted position, the auxiliary support plate 311 is outside one side of the adhesive positioning space 340. At this time, the support drive assembly 312 can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly or a linear motor translation drive assembly to realize the translation drive of the auxiliary support plate 311.

[0107] Please see Figure 16In some optional embodiments, the positioning and lifting assembly 333 includes a front lifting drive module 3331 and a rear lifting drive module 3332. The front lifting drive module 3331 is driven to connect with the front positioning member 332. The front positioning member 332 is driven to move up and down relative to the positioning and conveying assembly 310 under the drive of the front lifting drive module 3331. The rear lifting drive module 3332 is driven to connect with the rear positioning member 331. The rear positioning member 331 is driven to move up and down relative to the positioning and conveying assembly 310 under the drive of the rear lifting drive module 3332. The front lifting drive module 3331 and the rear lifting drive module 3332 drive the front positioning component 332 and the rear positioning component 331 to lift and lower independently, so that when the rear positioning component 331 rises to avoid the movement of the sponge, the front positioning component 332 is in a position that can cooperate with the sponge for positioning. Of course, in other embodiments, the front positioning component 332 and the rear positioning component 331 can also be driven to lift and lower simultaneously by the positioning lifting component 333. In this case, it is only necessary to lower the front positioning component 332 and the rear positioning component 331 together after the positioning conveying component 310 drives the sponge through the rear positioning component 331, so that the sponge can abut against the front positioning component 332 under the drive of the positioning conveying component 310.

[0108] The specific structures of the front lifting drive module 3331 and the rear lifting drive module 3332 can be selected according to actual needs. For example, the front lifting drive module 3331 and the rear lifting drive module 3332 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module. In this embodiment, both the front lifting drive module 3331 and the rear lifting drive module 3332 include multiple cylinder translation drive modules, and the output shafts of the cylinder translation drive modules are connected to the front positioning member 332 or the rear positioning member 331 respectively.

[0109] In some optional embodiments, the front and rear positioning mechanism 330 further includes a rear movable frame 335, with a rear positioning member 331 and a rear lifting drive module 3332 mounted on the rear movable frame 335. A rear positioning moving component 334 is drivenly connected to the rear movable frame 335. The rear movable frame 335 moves under the drive of the rear positioning moving component 334, thereby driving the rear positioning member 331 located on the rear movable frame 335 to move in directions closer to and further away from the front positioning member 332. The rear positioning moving component 334 indirectly drives the rear positioning member 331 to move by moving the rear movable frame 335, thereby driving the rear positioning member 331 and the rear lifting drive module 3332 to move together. The rear lifting drive module 3332 directly drives the rear positioning member 331 to lift and lower. Of course, in other embodiments, the rear lifting drive module 3332 can also drive the rear movable frame 335 to lift and lower, while the rear positioning moving component 334 and the rear positioning member 331 are mounted on the rear movable frame 335.

[0110] The specific structure of the rear positioning moving component 334 can be selected according to actual needs. For example, in some optional embodiments, the rear positioning moving component 334 includes a rear positioning drive motor 3341, multiple positioning transmission gears 3342, and multiple positioning transmission racks 3343. The rear positioning drive motor 3341 is mounted on the rear movable frame 335. The rear positioning drive motor 3341 is driven and connected to the multiple positioning transmission gears 3342. The positioning transmission racks 3343 extend along the conveying direction of the positioning conveying component 310. The multiple positioning transmission racks 3343 are arranged side by side, and the positioning transmission gears 3342 are correspondingly connected to the positioning transmission racks 3343. The rear positioning drive motor 3341 drives the positioning transmission gears 3342 to rotate, so that the positioning transmission gears 3342 move along the positioning transmission racks 3343, thereby driving the rear positioning drive motor 3341 and the rear movable frame 335 to move along the positioning transmission racks 3343. Of course, the rear positioning and moving component 334 can also be a screw drive component, a rotary motor translation drive component, a belt translation drive component, a cylinder translation drive component, or a linear motor translation drive component, etc., and is not limited to this example.

[0111] Please see Figure 17 Since the length of the sponge in the conveying direction of the positioning and conveying assembly 310 is usually relatively large, this results in a relatively long front-to-back length of the side positioning member 321. To improve the transmission stability of the side positioning member 321, in some optional embodiments, the side positioning drive assembly 322 includes a side positioning drive motor 3221, a positioning drive shaft 3222, a front synchronous belt module 3223, and a rear synchronous belt module 3224. The side positioning drive motor 3221 is drivenly connected to the positioning drive shaft 3222, and the positioning drive shaft 3222 is respectively connected to... The front synchronous belt module 3223 and the rear synchronous belt module 3224 are connected by a drive. The front synchronous belt module 3223 is connected to the front end of the two side positioning members 321 respectively, and the rear synchronous belt module 3224 is connected to the rear end of the two side positioning members 321 respectively. The front synchronous belt module 3223 and the rear synchronous belt module 3224 can drive the front and rear sides of the side positioning members 321 to move, thereby improving the stress stability of the side positioning members 321 and preventing the side positioning members 321 from deflecting in the conveying direction of the positioning and conveying assembly 310. It should be noted that, since the front synchronous belt module 3223 is usually composed of a synchronous belt and two synchronous pulleys, and the synchronous belt is arranged around the two synchronous pulleys, when the synchronous belt moves in a cycle, the synchronous belt located between the synchronous pulleys is actually composed of two segments moving in opposite directions. Therefore, the two side positioning members 321 can be connected to the two segments of the synchronous belt moving in opposite directions respectively, so that the two side positioning members 321 can move synchronously under the drive of the front synchronous belt module 3223. The same applies to the rear synchronous belt module 3224.

[0112] Of course, the side positioning drive assembly 322 can also be a screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly. For example, the side positioning drive assembly 322 includes two rotary motor translation drive assemblies, which are connected to the two side positioning members 321 and drive the side positioning members 321 to move respectively. This example is not limited to this one.

[0113] The control device is connected to the sponge coating device, sponge bonding and conveying device, sponge bonding and positioning device, and sponge pressing device via signal connections. The control device can employ a PLC controller, electronic calculator, control circuit, etc., and its structure and related control software are well-known technologies in the automation industry, and will not be listed or elaborated upon here. It can achieve signal connections with the sponge coating device, sponge bonding and conveying device, sponge bonding and positioning device, and sponge pressing device via wireless or wired connections. Wireless connections can be achieved through Bluetooth, Wi-Fi, 2G / 3G / 4G / 5G, etc.

[0114] Specifically, the control device controls each conveying component and each driving component of the sponge coating device, sponge bonding and conveying device, sponge bonding and positioning device, and sponge pressing device, thereby controlling each conveying component to convey the sponge and controlling each driving component to drive the corresponding parts to move, thus achieving automated control. The signal connection and control method of the control device are technologies known to those skilled in the art and will not be described in detail here.

[0115] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
