Description

Technical Field

[0001] This utility model relates to the field of adhesive applicator technology, specifically an automatic sponge adhesive applicator. Background Technology

[0002] The automatic sponge pasting machine is an industrial automation device specifically designed to paste sponges (or other soft materials) onto the surfaces of various substrates (such as wood, metal, plastic, and fabric). It automates the core processes of feeding, positioning, pasting, pressing, and collecting materials, replacing traditional manual operations. This significantly improves production efficiency, ensures consistent pasting quality, and reduces labor costs and intensity. It is widely used in furniture, automotive, and packaging manufacturing industries.

[0003] Existing automatic sponge bonding machines typically use conveyor belts to transport the substrate and photoelectric sensors to detect the edge position of the substrate in real time. When the substrate deviates, a correction device such as a cylinder is used to correct it, enabling rapid positioning of the substrate when bonding the sponge to it. However, the correction accuracy of the correction device is based on the sensitivity of the photoelectric sensor, which is susceptible to interference from external light, temperature and humidity changes, and dust in the air, leading to sensitivity deviations. This results in insufficient correction accuracy of the correction device, causing significant positional deviations (lateral offset and angular skew) when the substrate and sponge enter the bonding station. Consequently, quality problems such as misalignment, skewness, exposed substrate, or functional failure occur when the sponge is bonded to the substrate. Therefore, an automatic sponge bonding machine is now provided that eliminates the drawbacks of existing devices. Utility Model Content

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0041] In one embodiment, such as Figures 1-6As shown, an automatic sponge pasting machine includes a first support frame 1, a support base plate 9 fixedly connected to the top of the first support frame 1, a third support frame 7 fixedly connected to the top of the support base plate 9, a first conveyor belt 6 and a second conveyor belt 8 symmetrically arranged on the outer side of the third support frame 7, both the first conveyor belt 6 and the second conveyor belt 8 being installed at the top of the first support frame 1, the support base plate 9 being located between the first conveyor belt 6 and the second conveyor belt 8, a second support frame 4 fixedly connected to one side of the first support frame 1, a unwinding roller 3 rotatably connected to one end of the second support frame 4, a release film wound on the unwinding roller 3, and multiple sponge strips equidistantly adhered to the surface of the release film, a conveying assembly 5 installed at the top of the second support frame 4, and a conveying component 5 installed at the top of the inner wall of the third support frame 7. The first moving component 10 has a fourth pneumatic push rod 17 installed at its bottom end, and a first clamping component 11 installed at the bottom end of the fourth pneumatic push rod 17. A second pneumatic push rod 12 and a second moving component 14 are symmetrically arranged on the outer side of the first moving component 10. The second pneumatic push rod 12 and the second moving component 14 are both installed on the top of the inner wall of the third support frame 7. The first moving component 10 is located between the second pneumatic push rod 12 and the second moving component 14. The output end of the second pneumatic push rod 12 is fixedly connected to an extrusion plate 13. A third pneumatic push rod 15 is installed at the bottom end of the second moving component 14. The output end of the third pneumatic push rod 15 is fixedly connected to a second clamping component 16. A positioning mechanism for conveying and positioning the substrate is provided on the support base plate 9.

[0042] Positioning mechanisms include:

[0043] Two support baffles 2012 are symmetrically fixedly connected to the top of the support base plate 9. Two first limiting blocks 208 are symmetrically arranged on the outer side of one support baffle 2012, and two second limiting blocks 209 are symmetrically arranged on the outer side of the other support baffle 2012. The two second limiting blocks 209 are respectively located at one end of the two first limiting blocks 208. Two third limiting blocks 2013 are symmetrically arranged at the end of one support baffle 2012 away from the other support baffle 2012. Two support blocks are symmetrically fixedly connected to the top of the support base plate 9. The two support blocks are located between the two third limiting blocks 2013. The first limiting blocks 208, the second limiting blocks 209, and the third limiting blocks 2013 are all fixedly connected to the support base plate 9. The top of the first limiting blocks 208, the second limiting blocks 209, and the third limiting blocks 2013 are all fixedly connected to positioning blocks 2014. A limiting sleeve groove for fitting the positioning blocks 2014 is opened on the base material.

[0044] In this embodiment, during use, the substrate is conveyed to the area below the second clamping assembly 16 via the second conveyor belt 8. At this time, the substrate can be conveniently and automatically positioned by the cooperation of the second moving assembly 14, the third pneumatic push rod 15, the second clamping assembly 16, and the positioning mechanism. Then, the substrate can be lifted and moved by the positioning mechanism, so that the substrate can be conveyed at equal distances and positioned again. Then, the first moving assembly 10 is activated to drive the first clamping assembly 11 to move above the conveying assembly 5, and the conveying assembly 5 is activated to pull the release film and sponge strip on the unwinding roller 3, so that the unwinding roller 3 can be unwound.

[0045] When one end of the sponge strip moves to below the first clamping assembly 11, the sponge strip can be accurately pasted onto the upper surface of the substrate through the cooperation of the first moving assembly 10, the first clamping assembly 11, the fourth pneumatic push rod 17, and the positioning mechanism. This achieves the purpose of accurately pasting the sponge strip. Then, the above operation is repeated to convey subsequent substrates in sequence and make the unwinding roller 3 continue to unwind. At the same time, the positioning mechanism can convey the substrate at equal intervals and reposition it. Then, the second pneumatic push rod 12 is activated to push the extrusion plate 13 up and down. This allows the extrusion plate 13 to extrude the sponge strip, effectively preventing the sponge strip from not being firmly bonded to the substrate. Then, the above operation is repeated to convey the substrate firmly bonded to the sponge strip to the upper surface of the first conveyor belt 6. At this time, the first conveyor belt 6 is activated to convey the substrate, which can effectively avoid quality problems such as misalignment, skewing, exposure of the substrate, or functional failure caused by positional deviation when the sponge is bonded to the substrate.

[0046] In one embodiment, such as Figures 2-6 As shown, the positioning mechanism also includes a push component disposed on the support base plate 9;

[0047] The push component includes: a support plate 201 fixedly connected to one end of the bottom of the support base plate 9, an electric push rod 202 installed at one end of the support plate 201, and a movable push plate 206 fixedly connected to the output end of the electric push rod 202.

[0048] A first guide assembly is provided on the supporting base plate 9;

[0049] A conveying assembly is installed on the supporting base plate 9;

[0050] The first guide assembly includes: two linear guide rails 2015 symmetrically fixedly connected to the bottom end of the support base plate 9, a movable push plate 206 located below the two linear guide rails 2015, and a movable slide table slidably sleeved on the outer wall of each of the two linear guide rails 2015, with the movable slide table fixedly connected to the movable push plate 206.

[0051] The conveying assembly includes: two conveying push plates 2010 symmetrically arranged above the support base plate 9, two support baffles 2012 located between the two conveying push plates 2010, two conveying push plates 2010 located between two first limiting blocks 208, and two conveying push plates 2010 located between two second limiting blocks 209.

[0052] Limiting components are provided on the conveyor pusher plate 2010;

[0053] The movable push plate 206 is equipped with a lifting component;

[0054] The limiting component includes three sets of limiting plates 2011 that are laterally and equidistantly fixed to the top of the conveying push plate 2010. Two sets of limiting plates 2011 are located on one side of two support baffles 2012 respectively. Through the cooperation of the pushing component, the first guiding component, the conveying component and the limiting component, the substrate can be moved laterally, thereby enabling stable conveying of the substrate.

[0055] In one embodiment, such as Figures 4-6 As shown, the lifting assembly includes: a lifting push plate 203 disposed below the movable push plate 206, and two first pneumatic push rods 205 symmetrically installed at the bottom end of the lifting push plate 203, the output ends of the two first pneumatic push rods 205 being fixedly connected to the movable push plate 206.

[0056] A second guide assembly is provided on the lifting push plate 203;

[0057] The second guiding assembly includes two sets of lifting push rods 207 symmetrically fixedly connected to the top of the lifting push plate 203. Both sets of lifting push rods 207 pass through the movable push plate 206 to the top of the supporting base plate 9. The two sets of lifting push rods 207 are respectively located at the bottom of the two conveying push plates 2010. The two conveying push plates 2010 are respectively fixedly connected to the two sets of lifting push rods 207. A straight groove for sliding of the lifting push rods 207 is opened at the position where the supporting base plate 9 meets the lifting push rods 207. A sliding sleeve 204 is slidably sleeved on the outer wall of the lifting push rod 207. The movable push plate 206 is fixedly connected to the outer wall of the sliding sleeve 204. Through the cooperation of the lifting assembly and the second guiding assembly, the substrate can be stably lifted and lowered by the conveying push plate 2010, thereby enabling equidistant conveying of the substrate.

[0058] The above embodiment discloses an automatic sponge pasting machine. In use, the substrate is transported to the area below the second clamping assembly 16 via the second conveyor belt 8. At this time, the third pneumatic push rod 15 is activated to push the second clamping assembly 16 to rise and fall stably, thereby clamping the substrate through the second clamping assembly 16. Then, the second moving assembly 14 is activated to drive the third pneumatic push rod 15 to move laterally. At this time, the second clamping assembly 16, driven by the third pneumatic push rod 15, moves the substrate above the two third limiting blocks 2013. Then, the third pneumatic push rod 15 is activated to drive the second clamping assembly 16 to rise and fall, thereby stably placing the substrate on the upper surface of the two third limiting blocks 2013. The substrate is supported by two support blocks. At this time, the substrate is sleeved on the outer wall of the positioning card block 2014 on the third limiting block 2013 through the limiting sleeve groove, thereby enabling convenient and automatic positioning of the substrate.

[0059] Then, the electric push rod 202 is activated to push the movable push plate 206 to move laterally. At this time, the movable slide table slides along the outer wall of the linear guide rail 2015 under the drive of the movable push plate 206. At the same time, the sliding sleeve 204, driven by the movable push plate 206, drives the conveying push plate 2010 and the lifting push plate 203 to move synchronously through the lifting push rod 207, until the two conveying push plates 2010 move between the two third limit blocks 2013 and are located below the substrate. At this time, the electric push rod 202 is stopped and the first pneumatic push rod is activated. 205 pushes the lifting push plate 203 to rise, and at the same time, the lifting push rod 207 pushes the conveying push plate 2010 to rise synchronously under the push of the lifting push plate 203. When the conveying push plate 2010 contacts the lower surface of the substrate, the substrate is pushed by the conveying push plate 2010 and separates from the outer wall of the third limiting block 2013 and the positioning block 2014. At the same time, the substrate can be limited by the limiting plate 2011. Then, the electric push rod 202 is started to drive the moving push plate 206 to reset, so that the substrate can be conveyed at equal distances.

[0060] When the substrate moves above the two first limiting blocks 208, the first pneumatic push rod 205 is activated to drive the lifting push plate 203 to descend, so that the substrate can contact a support baffle 2012 and the upper surface of the two first limiting blocks 208. At the same time, the substrate is sleeved on the outer wall of the positioning card block 2014 on the first limiting block 208 through the limiting sleeve groove, so that the substrate can be conveniently and automatically positioned. Then, the first moving component 10 is activated to drive the first clamping component 11 to move above the conveying component 5, and the conveying component 5 is activated to pull the release film and sponge strip on the unwinding roller 3, so that the unwinding roller 3 can be unwound.

[0061] When one end of the sponge strip moves to below the first clamping assembly 11, the fourth pneumatic push rod 17 is activated to drive the first clamping assembly 11 to move up and down stably. This allows the edge of a sponge strip to be clamped by the first clamping assembly 11. Then, the first moving assembly 10 is activated to drive the fourth pneumatic push rod 17 to move longitudinally. At this time, the first clamping assembly 11, driven by the fourth pneumatic push rod 17, moves the sponge strip above the two first limit blocks 208. Then, the fourth pneumatic push rod 17 is activated to drive the first clamping assembly 11 to move up and down. This allows the sponge strip to be accurately pasted onto the upper surface of the substrate by the first clamping assembly 11, thereby achieving the purpose of accurately pasting the sponge strip.

[0062] Then, repeat the above operation to sequentially convey the subsequent substrates and make the unwinding roller 3 continue to unwind. At the same time, the substrate with the sponge strip attached moves to the upper surface of the two second limit blocks 209 under the conveying of the two conveying push plates 2010 and contacts the upper surface of the other support baffle 2012. At this time, the substrate is sleeved on the outer wall of the positioning card block 2014 on the second limit block 209 through the limit sleeve groove, so that the substrate can be conveniently and automatically positioned. Then, the second pneumatic push rod 12 is activated to push the extrusion plate 13 to rise and fall, so that the sponge strip can be extruded through the extrusion plate 13, effectively preventing the sponge strip from being poorly bonded to the substrate.

[0063] Then, repeat the above operation to transport the substrate firmly bonded to the sponge strip to the upper surface of the first conveyor belt 6. At this time, start the first conveyor belt 6 to transport the substrate, which can effectively avoid quality problems such as misalignment, skewing or functional failure caused by positional deviation when the sponge is bonded to the substrate.

[0064] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
