Description

Technical Field

[0001] This invention relates to the field of adhesive strip technology, and more specifically, to an automatic deburring device for adhesive strips and its processing method. Background Technology

[0002] Rubber strips are long, strip-shaped components, typically made of elastic materials such as rubber, with specific shapes and sizes. They have wide applications in numerous industrial fields and daily life. In automobile manufacturing, rubber strips are used to seal car doors, windows, and other parts, providing dustproofing, waterproofing, and sound insulation. In the construction industry, rubber strips are used for sealing doors and windows and for fixing glass. In the electronics and electrical appliance field, rubber strips are used for shock absorption, moisture protection, and insulation. However, during the manufacturing process, burrs often form on the edges of rubber strips. These burrs not only affect the appearance quality of the rubber strips but may also damage other components during use, and even affect their sealing and shock absorption performance. Therefore, deburring is necessary for rubber strips.

[0003] According to patent document CN119238829B, an automatic deburring device is disclosed, including a molding die with multiple molding cavities inside and an encapsulation groove on the surface of the molding die. The inner wall of the encapsulation groove has multiple pouring gates. In the process of semiconductor injection molding, the invention uses a first cutter to remove burrs formed on the outside of the pouring gate when moving towards it, preventing burrs from remaining at the pouring gate after semiconductor molding. Burrs can cause friction between the molded cavity and the semiconductor during removal, affecting the accuracy of the molded cavity over long-term production. Furthermore, a second cutter moves towards the groove to remove residual adhesive in the encapsulation groove, preventing the adhesive from solidifying and being unable to be removed promptly. This adhesive can then obstruct the movement of the encapsulation strip during subsequent installation and cause friction between the encapsulation strip and the encapsulation groove, affecting their fit and reducing service life.

[0004] During the deburring process of rubber strips, in order to ensure the deburring effect and surface quality, the worn sandpaper usually needs to be replaced after sanding for a certain period of time. However, this sandpaper replacement operation is not simple and quick. It requires the sanding device to be completely stopped to ensure operational safety and avoid equipment damage. Only after the sanding device has completely stopped operating can the operator carefully remove the current sandpaper and install the new sandpaper. This series of sandpaper replacement steps involves multiple steps such as stopping the machine, disassembling, and installing. It is precisely because the sandpaper replacement process is so cumbersome and time-consuming that it inevitably has a significant impact on the efficiency of the entire sanding work. Each sandpaper replacement takes a certain amount of time, during which the sanding work is stagnant and cannot continue. Frequent machine shutdowns for paper replacement not only prolong the overall sanding time but may also interrupt the operator's sanding rhythm, further reducing work efficiency.

[0020] In addition, the present invention also relates to a processing method for an automatic deburring device for adhesive strips, comprising the following steps:

[0021] Step 1: Place the adhesive strip to be processed inside the two clamping plates of the control component, and push the push-pull plate inward by activating the two second electric push rods so that the clamping plates clamp and fix the adhesive strip.

[0022] Step 2: Simultaneously start the second motor, which drives the sector teeth to reciprocate through the transmission system, thereby driving the gear column rod to rotate intermittently in the forward and reverse directions. This causes the rack rod to drive the clamping plate side plate and slide rod to make linear reciprocating motion in the groove of the guide block, realizing the reciprocating movement of the rubber strip in the horizontal direction.

[0023] Step 3: Start the electric push rod, pull the moving frame push plate to move the rubber strip position control mechanism to the rear, so that the fixed rubber strip enters the inner wall of the grinding mechanism;

[0024] Step 4: During the movement, the triangular abutment pushes the elliptical base block to move inward, causing the expansion and contraction roller connecting block to slide in the side plate groove, so that the expansion and contraction roller moves inward, stretching the sandpaper sleeved on the outer wall of the expansion and contraction roller to make it taut and adhere to the surface of the adhesive strip.

[0025] Step 5: Start the motor, which drives the second transmission disc to rotate through the transmission disc and the track, providing power to the entire sanding assembly. The fourth transmission disc at both ends of the top take-up roller is connected to the fifth transmission disc at both ends of the columnar horizontal rotating rod through the third track, so that the take-up roller rotates and drives the take-up roller to rotate, continuously rolling up the used sandpaper. At the same time, new sandpaper is unrolled from the sandpaper roller, realizing automatic sandpaper replacement.

[0026] Step Six: During deburring, the side tension roller and bottom support roller stabilize the sandpaper to prevent it from shifting or loosening. The control component controls the position and movement trajectory of the rubber strip during deburring according to the preset program and parameters, ensuring that all parts of the rubber strip surface are evenly polished. After a period of polishing, the surface of the rubber strip is processed to be flat, meeting the required process requirements.

[0027] The beneficial effects of this invention are as follows:

[0028] This invention, by incorporating a grinding mechanism and a rubber strip position control mechanism, achieves automated and high-precision deburring of the rubber strip surface. Through the coordinated operation of a precisely designed mechanical structure and an intelligent control system, it not only significantly improves processing efficiency but also ensures the stability and consistency of processing quality. Specifically, the device utilizes an electric push rod, a motor, and a complex transmission system to automatically tension and replace the sandpaper, avoiding the tediousness and errors of manual sandpaper replacement. Simultaneously, the precise control of the rubber strip position by the control components ensures more uniform and comprehensive deburring, effectively eliminating grinding dead zones or over-grinding problems that may occur in traditional processing methods. Furthermore, the design of this device fully considers ease of operation and safety, providing an efficient and reliable solution for rubber strip processing in industrial production.

The outer walls of the two take-up roller rotating rods 1214 are located inside the two sets of take-up roller rotating rod connecting blocks 1213. Each of the two winding rollers 1214 is fixedly connected to one side. A third transmission disc 1216 is fixedly connected to both sides of the outer wall of the two winding roller connecting blocks 1213. A second track 1217 is fitted onto the outer wall of each of the two sets of third transmission discs 1216.

Electric push rod connecting plates 1223 are fixedly connected to the top of the two sets of L-shaped guide blocks 1212. Electric push rods 1224 are fixedly connected to the top center of the electric push rod connecting plates 1223. The outer center of the two sandpapers 1226 is fitted onto the outer walls of the upper and lower sets of take-up and expand rollers 128. The outer sides of the two sandpapers 1226, away from the sandpaper roller 1225, are fitted onto the outer walls of the two take-up rollers 1215. The rubber strip position control mechanism 2 includes a moving frame 21. A control component 22 is provided on the front side of the moving frame 21. The device includes two uprights 211. A movable frame push-pull plate 212 is fixedly connected to the top of the rear side of each upright 211. The rear side of the movable frame push-pull plate 212 is fixedly connected to the front end of an electric push rod 1224. Base plate connecting blocks 213 are fixedly connected to the top and bottom of the rear side of each upright 211. The outer walls of both sets of left and right base plate connecting blocks 213 are slidably connected to the inner walls of the two sets of left and right L-shaped guide blocks 1212. Triangular abutments 214 are fixedly connected to the middle of the inner side of each set of base plate connecting blocks 213. The inner sides of both sets of triangular abutments 214 are in contact with the outer walls of the two sets of elliptical base blocks 127.

[0043] When deburring the rubber strip is required, firstly, the rubber strip is fixed inside the control component 22. Then, the electric push rod 1224 is activated. The electric push rod 1224 pulls the moving frame push-pull plate 212, causing the rubber strip position control mechanism 2 to move backward as a whole. At the same time, the rubber strip fixed by the control component 22 enters the inner wall of the grinding mechanism 1. The triangular abutment 214 in the middle of the inner side of the two sets of base plate connecting blocks 213 will move backward synchronously. Because the inner side of the triangular abutment 214 is close to the elliptical base block... When the outer wall of 127 is attached, the elliptical base block 127 will be pushed to move inward during the backward movement. The elliptical base block 127 drives the expansion roller connecting block 126 to slide in the side plate groove 122, thereby causing the expansion roller 128 to move inward. As the expansion roller 128 moves inward, the sandpaper 1226 on the outer wall of the expansion roller 128 will be stretched and unfolded, so that it is in a taut state and attached to the surface of the rubber strip fixed inside the control component 22, so as to better polish the surface of the rubber strip.

[0044] At the same time, the motor 114 is started, and the output end of the motor 114 drives the transmission disk 115 to rotate. The transmission disk 115 drives the second transmission disk 117 to rotate through the track 116, thereby providing power to the entire grinding assembly 12. The fourth transmission disk 1218 at both ends of the top take-up roller 1214 is connected to the fifth transmission disk 1221 at both ends of the columnar horizontal rotating rod 1220 through the third track 1222. Under the power transmission, the take-up roller 1214 will drive the take-up roller 1215 to rotate. When the take-up roller 1215 rotates, it will continuously roll up the used sandpaper 1226, while the new sandpaper 1226 will continuously unfold from the sandpaper roller 1225, realizing the automatic replacement of sandpaper.

[0045] The control component 22 controls the position and movement trajectory of the rubber strip during deburring according to the preset program and parameters, ensuring that all parts of the rubber strip surface can be polished evenly. During deburring, the side tension roller 129 and the bottom support roller 125 stabilize the sandpaper 1226, preventing the sandpaper 1226 from shifting or loosening during deburring, thus ensuring the accuracy and quality of polishing. After a period of polishing, the surface of the rubber strip will be processed to be flat, meeting the required process requirements.

The middle of the top of the two clamping plate side plates 22110 is fixedly connected to the second electric push rod 22112. The front and rear sides of the inner walls of the two clamping plate side plates 22110 are slidably connected to the columnar push-pull crossbars 22111. The outer ends of the left and right sets of columnar push-pull crossbars 22111 are fixedly connected to the push-pull plates 22113. The inner ends of the left and right sets of columnar push-pull crossbars 22111 extend to the inner side of the two clamping plate side plates 22110 and are fixedly connected to the clamping plates 22114. The outer ends of the two second electric push rods 22112 are fixedly connected to the inner side of the two push-pull plates 22113.

[0047] When fixing the adhesive strip, first place the adhesive strip inside the two clamping plates 22114. Then, activate the two second electric push rods 22112. After activation, the two second electric push rods 22112 will push the two push-pull plates 22113 inward. The push-pull plates 22113 drive the columnar push-pull crossbar 22111 to slide on the inner wall of the clamping plate side plate 22110, thereby causing the clamping plates 22114 to move inward and tightly clamp the adhesive strip between the two clamping plates 22114, completing the fixing of the adhesive strip. At this time, activate the second motor 2210. The output end of the second motor 2210 drives the sixth transmission disc 2211 to rotate. The sixth transmission disc 2211 drives the seventh transmission disc 2213 to rotate through the fourth track 2212. The seventh transmission disc 2213 drives the columnar rotating crossbar 2214 to rotate. The rotation of the columnar rotating crossbar 2214 in turn drives the rotating rods at both ends. Rotating rod 2215 drives the second rotating rod 2216 to move during rotation. The second rotating rod 2216 pulls the sector tooth 2217 to oscillate back and forth. Since the sector tooth 2217 meshes with gear 229, its oscillation will drive gear 229 to drive gear column rotating rod 228 to rotate intermittently in the forward and reverse directions. The rotation of gear column rotating rod 228 causes the rack rod 2219 meshing with it to make linear reciprocating motion in rack rod guide plate 226. The rack rod 2219 drives the clamping plate side plate 22110 and slide rod 2218 to slide synchronously in the groove 227 of guide block 225, thereby realizing that the rubber strip clamped between the two clamping plates 22114 moves back and forth in the horizontal direction according to the preset program. With the grinding action of grinding component 12, it is ensured that all areas of the rubber strip surface can be fully and evenly ground, and finally achieves the ideal flat processing effect.

[0048] In addition, the present invention also relates to a processing method for an automatic deburring device for adhesive strips, comprising the following steps:

[0049] Step 1: Place the adhesive strip to be processed inside the two clamping plates 22114 of the control component 22, and push the push-pull plate 22113 to move inward by activating the two second electric push rods 22112, so that the clamping plates 22114 clamp and fix the adhesive strip.

[0050] Step 2: Simultaneously start the second motor 2210, which drives the sector tooth 2217 to reciprocate through the transmission system, thereby driving the gear column rod 228 to rotate intermittently in the forward and reverse directions. This causes the rack rod 2219 to drive the clamping plate side plate 22110 and the slide rod 2218 to perform linear reciprocating motion within the groove 227 of the guide block 225, thus realizing the reciprocating movement of the rubber strip in the horizontal direction.

[0051] Step 3: Start the electric push rod 1224, pull the moving frame push plate 212 to drive the rubber strip position control mechanism 2 to move backward, so that the fixed rubber strip enters the inner wall of the grinding mechanism 1;

[0052] Step 4: During the movement, the triangular abutment 214 pushes the elliptical base block 127 to move inward, causing the expansion roller connecting block 126 to slide in the side plate groove 122, so that the expansion roller 128 moves inward, stretching the sandpaper 1226 on the outer wall of the expansion roller 128 to be in a taut state and adhering to the surface of the adhesive strip.

[0053] Step 5: Start the motor 114, which drives the second transmission disc 117 to rotate through the transmission disc 115 and the track 116, providing power to the entire sanding assembly 12. The fourth transmission disc 1218 at both ends of the top take-up roller 1214 is connected to the fifth transmission disc 1221 at both ends of the columnar horizontal rotating rod 1220 through the third track 1222, so that the take-up roller 1214 drives the take-up roller 1215 to rotate, continuously winding up the used sandpaper 1226. At the same time, the new sandpaper 1226 unfolds from the sandpaper roller 1225, realizing automatic sandpaper replacement.

[0054] Step Six: During deburring, the side tension roller 129 and the bottom support roller 125 stabilize the sandpaper 1226 to prevent it from shifting or loosening. The control component 22 controls the position and movement trajectory of the rubber strip during deburring according to the preset program and parameters, ensuring that all parts of the rubber strip surface can be polished evenly. After a period of polishing, the surface of the rubber strip is processed to be flat, meeting the required process requirements.

[0055] The working principle of this invention is as follows: When fixing the adhesive strip, the adhesive strip is first placed inside the two clamping plates 22114. Then, the two second electric push rods 22112 are activated. After activation, the two second electric push rods 22112 push the two push-pull plates 22113 inward. The push-pull plates 22113 drive the columnar push-pull crossbar 22111 to slide on the inner wall of the clamping plate side plate 22110, thereby causing the clamping plates 22114 to move inward and tightly clamp the adhesive strip between the two clamping plates 22114, thus completing the fixing of the adhesive strip. Afterward, the electric push rod 1224 is activated. The electric push rod 1224 pulls the moving frame push-pull plate 212, causing the adhesive strip position control mechanism 2 to move backward as a whole. At the same time, the controlled component 22 is fixed. The rubber strip enters the inner wall of the grinding mechanism 1. The triangular abutment 214 in the middle of the inner side of the two sets of base plate connecting blocks 213 moves backward synchronously. Since the inner side of the triangular abutment 214 is in contact with the outer wall of the elliptical base block 127, it will push the elliptical base block 127 to move inward during the backward movement. The elliptical base block 127 drives the expansion roller connecting block 126 to slide in the side plate slide groove 122, thereby causing the expansion roller 128 to move inward. As the expansion roller 128 moves inward, the sandpaper 1226 sleeved on the outer wall of the expansion roller 128 will be stretched and unfolded, so that it is in a taut state and adheres to the surface of the rubber strip fixed inside the control component 22, so as to better grind the surface of the rubber strip. At the same time, the motor 114 is started. The output end of machine 114 drives the transmission disc 115 to rotate. The transmission disc 115 drives the second transmission disc 117 to rotate via the track 116, thereby providing power to the entire grinding assembly 12. The fourth transmission discs 1218 at both ends of the top take-up roller 1214 are connected to the fifth transmission discs 1221 at both ends of the columnar horizontal rotating rod 1220 via the third track 1222. Under power transmission, the take-up roller 1214 drives the take-up roller 1215 to rotate. When the take-up roller 1215 rotates, it continuously rolls up the used sandpaper 1226, while new sandpaper 1226 continuously unfolds from the sandpaper roller 1225, realizing automatic sandpaper replacement. At this time, the second motor 2210 is started, and the output end of the second motor 2210 drives the second transmission disc 117 to rotate via the track 116. The sixth transmission disc 2211 rotates, which in turn drives the seventh transmission disc 2213 to rotate via the fourth track 2212. The seventh transmission disc 2213 drives the cylindrical rotating crossbar 2214 to rotate, which in turn drives the rotating rods 2215 at both ends to rotate. During the rotation, the rotating rods 2215 drive the second rotating rod 2216 to move. The second rotating rod 2216 pulls the sector tooth 2217 to oscillate back and forth. Since the sector tooth 2217 meshes with the gear 229, its oscillation drives the gear 229 to drive the gear column rotating rod 228 to rotate intermittently in both directions. The rotation of the gear column rotating rod 228 causes the rack rod 2219, which meshes with it, to perform linear reciprocating motion within the rack rod guide plate 226.The rack and pinion 2219 drives the clamping plate side plate 22110 and the slide bar 2218 to slide synchronously within the groove 227 of the guide block 225. This allows the rubber strip clamped between the two clamping plates 22114 to reciprocate horizontally according to a preset program. Combined with the grinding action of the grinding component 12, this ensures that all areas of the rubber strip surface receive sufficient and uniform grinding, ultimately achieving an ideal smooth finish.
