Description

Technical Field

[0001] This utility model relates to the field of rubber ring detection technology, specifically to a rubber ring flipping mechanism. Background Technology

[0002] With the continuous progress of society, quality inspection is required for some products with large production volumes after processing. For example, some small rubber rings need to be inspected for size and surface after production. The traditional inspection method is to inspect by human eyes, which is inefficient. Therefore, automated inspection equipment has gradually emerged. In the process of automatic inspection, both sides of the rubber ring need to be inspected. Therefore, after the inspection of one side is completed, it needs to be flipped to the other side for inspection.

[0003] Existing patents, such as the Chinese Patent Publication No. CN218823997U, entitled "Double-Disc Rubber Ring Hidden Crack Detection Machine," include a turning device for reversing the front and back sides of a rubber ring. The turning device includes a turning frame, a transmission wheel set mounted on the turning frame, and a turning drive motor. A first turning belt is fitted onto a second driven wheel and a third driven wheel and moves reciprocally. A second turning belt is sequentially fitted onto a drive wheel, a first driven wheel, a third driven wheel, a fourth driven wheel, a fifth driven wheel, and a sixth driven wheel and moves reciprocally. At the third driven wheel, the first turning belt is located inside the second turning belt. The second turning belt forms a downwardly inclined groove. The third driven wheel is located at the bottom of the groove, and the second driven wheel is located at the opening of the groove.

[0004] Regarding the aforementioned technologies, the rubber ring is clamped and conveyed between the first and second turning belts for flipping. Since the first and second turning belts are tightly attached to each other before clamping the rubber ring, a large clamping force is used when the rubber ring enters the first and second turning belts for clamping and conveying. As a result, some rubber rings may be damaged, affecting the quality of the rubber ring. Utility Model Content

[0005] The purpose of this invention is to provide a rubber ring flipping mechanism, which aims to ensure that the rubber ring can be flipped while reducing the clamping force on the rubber ring, thereby reducing the impact on the quality of the rubber ring during flipping.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a first aspect, this utility model provides a rubber ring flipping mechanism, including an upper flipping machine and a lower flipping machine. The upper flipping machine includes an upper support, an upper driving roller, an upper driven roller, an upper conveyor belt, and an upper drive assembly. The upper driving roller and the upper driven roller are horizontally spaced apart. Both the upper driving roller and the upper driven roller are rotatably mounted on the upper support. The upper conveyor belt is synchronously wound around the upper driving roller and the upper driven roller. The upper drive assembly is used to drive the upper driving roller to rotate.

[0008] The lower tilting machine includes a lower support, a lower driven roller, a lower driving roller, a guide roller, a lower conveyor belt, and a lower drive assembly. The lower driving roller, the lower driven roller, and the guide roller are all parallel to the upper driving roller. The lower driving roller, the lower driven roller, and the guide roller are all rotatably mounted on the lower support. The lower driving roller and the lower driven roller are located below the upper tilting machine. The upper driving roller and the upper driven roller are located between the lower driving roller and the lower driven roller, with the upper driven roller positioned close to the lower driving roller. The guide roller is located directly above the upper driven roller. The lower conveyor belt is sequentially wound around the lower driven roller, the lower driving roller, and the guide roller. The lower drive assembly is used to drive the lower driving roller to rotate.

[0009] Both ends of the upper driven roller are fitted with a spreading bearing. The portion of the upper conveyor belt that is conveyed at the lower driving roller and the process section of the lower conveyor belt located between the lower driving roller and the guide roller are both clamping portions. The clamping portion of the upper conveyor belt is located between the two spreading bearings. The clamping portion of the lower conveyor belt abuts against the outer ring of the spreading bearing. There is a gap between the clamping portion of the upper conveyor belt and the clamping portion of the lower conveyor belt.

[0010] By adopting the above technical solution, after the rubber ring has been inspected on one side, it is placed on the upper turning machine. The rubber ring is conveyed by the upper conveyor belt until it enters the gap between the clamping parts of the upper and lower conveyor belts, and finally enters the lower conveyor belt, thus completing the turning of the rubber ring. Due to the action of the bearing, there is a gap between the clamping parts of the upper and lower conveyor belts, so the clamping force on the rubber ring is small, thereby reducing the possibility of the rubber ring being crushed due to turning and improving the quality of the rubber ring.

[0011] Optionally, the inner diameter of the spreading bearing is larger than the cross-sectional diameter of the upper driven roller's shaft, and the inner ring of the spreading bearing is fixedly installed on the lower bracket; the upper bracket is provided with adjusting frames corresponding to the shaft positions at both ends of the upper driven roller, and the shafts at both ends of the upper driven roller are respectively installed on the corresponding adjusting frames. The adjusting frames are slidably installed on the upper bracket in the arrangement direction of the upper driving roller and the upper driven roller, and the upper bracket is equipped with locking members for limiting the sliding position of the adjusting frames.

[0012] Optionally, the locking component includes a locking bolt, the adjusting frame has a first adjusting hole extending in the sliding direction of the adjusting frame, the locking bolt passes through the first adjusting hole and is threaded onto the upper bracket, and the head of the locking bolt abuts against the side of the adjusting frame away from the upper bracket.

[0013] Optionally, the upper support is provided with a sliding groove, the sliding groove extends toward the sliding direction of the adjusting frame, and the adjusting frame is fixedly installed with a sliding block, the sliding block being slidably installed in the sliding groove.

[0014] Optionally, the guide roller includes an adjusting rod and a roller body, the roller body being sleeved and rotatably mounted on the adjusting rod, and the lower conveyor belt being wound around the roller body; the lower support has second adjusting holes at both ends corresponding to the adjusting rod, the second adjusting holes extending toward the arrangement direction of the lower driven roller and the lower driving roller, and both ends of the adjusting rod being slidably mounted in the second adjusting holes; the lower support is equipped with adjusting components for adjusting the sliding position of the adjusting rod.

[0015] Optionally, both ends of the adjusting rod extend out of the lower bracket through the second adjusting hole. The adjusting component includes a mounting block and an adjusting bolt. The mounting block is fixedly installed at one end of the lower bracket corresponding to each of the second adjusting holes. The adjusting bolt is rotatably installed on the mounting block and threaded onto the adjusting rod.

[0016] Optionally, both the upper support located directly below the progress section of the upper conveyor belt and the lower support located directly below the progress section of the lower conveyor belt are fixedly installed with pads, and the progress sections of the upper and lower conveyor belts abut against the corresponding pads.

[0017] Optionally, mounting brackets are installed on opposite sides of the lower support, and pressure rollers are rotatably mounted on the mounting brackets. The pressure rollers abut against the progress section of the lower conveyor belt away from the pad.

[0018] Optionally, the upper drive assembly includes a driving pulley, a driven pulley, a belt, and a drive member. The driving pulley is rotatably mounted on the upper bracket, the driven pulley is sleeved on the upper driving roller, and the belt is synchronously wound around the driving pulley and the driven pulley. The drive member is used to drive the driving pulley to rotate.

[0019] Optionally, the upper bracket is covered with an isolation cover corresponding to the position of the upper drive assembly, and the driving pulley, the driven pulley and the belt are all located inside the isolation cover.

[0020] The beneficial effects of this utility model are as follows:

[0021] This invention incorporates a spreading bearing, creating a gap between the clamping parts of the upper and lower conveyor belts. This results in a smaller clamping force on the rubber ring during transport between these two belts, reducing the likelihood of the rubber ring being crushed. Attached Figure Description

[0030] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, solution, and effects of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0031] This application discloses a rubber ring flipping mechanism. (Refer to...) Figure 1 and Figure 2 The rubber ring flipping mechanism includes an upper flipper 1 and a lower flipper 2. The conveying path of the upper flipper 1 is shorter than that of the lower flipper 2. The upper flipper 1 includes an upper support 11, an upper drive roller 12, an upper driven roller 13, an upper conveyor belt 14, and an upper drive assembly 15. The upper drive roller 12 and the upper driven roller 13 are horizontally spaced apart. Both the upper drive roller 12 and the upper driven roller 13 are rotatably mounted on the upper support 11. The upper conveyor belt 14 is synchronously wound around the upper drive roller 12 and the upper driven roller 13. The upper drive assembly 15 is used to drive the upper drive roller 12 to rotate.

[0032] The lower tilting machine 2 includes a lower support 21, a lower driven roller 22, a lower driving roller 23, a guide roller 24, a lower conveyor belt 25, and a lower drive assembly 26. The lower driving roller 23, the lower driven roller 22, and the guide roller 24 are all parallel to the upper driving roller 12. The lower driving roller 23, the lower driven roller 22, and the guide roller 24 are all rotatably mounted on the lower support 21. The lower driving roller 23 and the lower driven roller 22 are both located below the upper tilting machine 1. The upper driving roller 12 and the upper driven roller 13 are located between the lower driving roller 23 and the lower driven roller 22, with the upper driven roller 13 positioned close to the lower driving roller 23. The guide roller 24 is located directly above the upper driven roller 13. The lower conveyor belt 25 is sequentially wound around the lower driven roller 22, the lower driving roller 23, and the guide roller 24. The lower drive assembly 26 is used to drive the lower driving roller 23 to rotate.

[0033] The upper support 11 is located directly below the progress section of the upper conveyor belt 14, and the lower support 21 is located directly below the progress section of the lower conveyor belt 25. Both the upper support 11 and the lower support 21 are fixedly installed with pads 3. The pads 3 extend in the conveying direction of the upper turning machine 1. The progress sections of the upper conveyor belt 14 and the lower conveyor belt 25 abut against the corresponding pads 3, thereby improving the conveying stability. The lower support 21 has mounting brackets 211 installed on both sides. The mounting brackets 211 are set vertically, and pressure rollers 212 are rotatably installed on both mounting brackets 211. The two pressure rollers 212 abut against the two sides of the progress section of the lower conveyor belt 25 away from the pads 3. The cooperation with the pads 3 further improves the conveying stability of the lower conveyor belt 25.

[0034] Reference Figure 2 and Figure 3 Both ends of the driven roller 13 are fitted with a spreading bearing 4, the outer diameter of which is larger than the roller diameter of the driven roller 13. The portion of the upper conveyor belt 14 that is conveyed at the lower drive roller 23, and the section of the lower conveyor belt 25 that is located between the lower drive roller 23 and the guide roller 24, are clamping parts 5. The clamping part 5 of the upper conveyor belt 14 is located between the two spreading bearings 4, and the clamping part 5 of the lower conveyor belt 25 abuts against the outer ring of the spreading bearing 4. There is a gap between the clamping part 5 of the upper conveyor belt 14 and the clamping part 5 of the lower conveyor belt 25. The width of the gap is larger than the thickness of the rubber ring to be tested, but smaller than the outer diameter of the rubber ring to be tested. This can reduce the clamping force on the rubber ring while ensuring that the rubber ring can be flipped, thereby reducing the impact on the quality of the rubber ring during flipping.

[0035] Reference Figure 1 and Figure 4 The upper drive assembly 15 includes a drive pulley 151, a driven pulley 152, a belt 153, and a drive component 154. The drive pulley 151 is rotatably mounted on the upper bracket 11, the driven pulley 152 is sleeved on the upper drive roller 12, and the belt 153 is synchronously wound around the drive pulley 151 and the driven pulley 152. The drive component 154 is a motor, which is fixedly mounted on the upper bracket 11. The output shaft of the drive component 154 is fixedly connected to the rotating shaft of the drive pulley 151, thereby driving the upper drive roller 12 to rotate, which in turn drives the upper conveyor belt 14. The upper bracket 11 is covered with an isolation cover 155 corresponding to the position of the upper drive assembly 15. The drive pulley 151, the driven pulley 152, and the belt 153 are all located inside the isolation cover 155, which serves as a protective function. The structure of the lower drive assembly 26 is the same as that of the upper drive assembly 15, and will not be described in detail here.

[0036] Reference Figure 2 and Figure 3The inner diameter of the bearing 4 is larger than the cross-sectional diameter of the shaft of the upper driven roller 13. The inner ring of the bearing 4 is fixedly installed on the lower bracket 21. The upper bracket 11 is provided with an adjusting frame 111 at the shaft positions at both ends of the upper driven roller 13. The adjusting frame 111 is slidably installed on the upper bracket 11 in the arrangement direction of the upper driving roller 12 and the upper driven roller 13. The upper bracket 11 has a sliding groove 112, which extends in the sliding direction of the adjusting frame 111. The adjusting frame 111 is fixedly installed with a sliding block 113, which is slidably installed in the sliding groove 112, so that the adjusting frame 111 can slide stably. The shafts at both ends of the upper driven roller 13 are respectively installed on... The corresponding adjusting frame 111; thus, when the upper conveyor belt 14 is loose or the gap between the clamping part 5 of the upper conveyor belt 14 and the clamping part 5 of the lower conveyor belt 25 needs to be finely adjusted, it can be adjusted by sliding the adjusting frame 111; the upper support 11 is equipped with a locking component, which includes a locking bolt 114, and the adjusting frame 111 is provided with a first adjusting hole 115, which extends in the sliding direction of the adjusting frame 111. The locking bolt 114 passes through the first adjusting hole 115 and is threaded onto the upper support 11, and the head of the locking bolt 114 abuts against the side of the adjusting frame 111 away from the upper support 11; when the locking bolt 114 is loosened, the adjusting frame 111 can be slid.

[0037] Reference Figure 2 , Figure 4 and Figure 6 The guide roller 24 includes an adjusting rod 241 and a roller body 242. The roller body 242 is sleeved on and rotatably mounted on the adjusting rod 241 via bearings. The lower conveyor belt 25 is sleeved on the roller body 242. The structure of the upper driven roller is the same as that of the guide roller 24, and will not be described again here. The lower support 21 has second adjusting holes 213 at both ends corresponding to the adjusting rod 241. The second adjusting holes 213 extend in the direction of the lower driven roller 22 and the lower driving roller 23. Both ends of the adjusting rod 241 pass through the second adjusting holes 213 and slide outside the lower support 21. The lower support 21 is equipped with an adjusting component, which includes a mounting block 214 and an adjusting bolt 215. The mounting block 214 is fixedly installed outside the lower support 21 and at one end of each adjusting hole. The adjusting bolt 215 extends in the direction of the second adjusting hole 213 and is rotatably mounted on the mounting block 214. The adjusting bolt 215 passes through the mounting block 214 and is threaded onto the adjusting rod 241, thereby adjusting the tension of the lower conveyor belt 25 by turning the adjusting bolt 215.

[0038] The implementation principle of the rubber ring flipping mechanism in this application embodiment is as follows: after the rubber ring has completed the inspection of one side, it is placed on the upper flipping machine 1. The rubber ring is conveyed by the upper conveyor belt 14 until it enters the gap between the clamping part 5 of the upper conveyor belt 14 and the clamping part 5 of the lower conveyor belt 25, and finally enters the lower conveyor belt 25 located below, thus completing the flipping of the rubber ring.

[0039] The above is a detailed description of the preferred embodiments of this disclosure. However, this disclosure is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this disclosure. All such equivalent modifications or substitutions are included within the scope defined by the claims of this disclosure.
