Description

Technical Field

[0001] This invention belongs to the field of ball processing, specifically relating to an automated ball processing system and its processing method. Background Technology

[0002] The process of processing wooden beads is as follows: grinding wooden rods into round shapes, pressing the round rods into beads, and drilling holes in the wooden beads. Taking Chinese patent "CN115609693B - An Automated Processing System for Wooden Beads" as an example, please refer to the appendix of the patent. Figure 2 This processing system first grinds square bars into round bars, then grinds the round bars into spherical beads, and finally drills holes in the round bars. This system has essentially achieved automated processing from square bars to perforated spherical beads. However, the system still has the following problems: First, the bar stock is fed into the rollers of the square bar grinding mechanism by gravity. This step cannot further improve the rounding efficiency of the square bars, thus affecting the efficiency of the entire processing system. Furthermore, jamming can occur during the loading process, preventing the bar stock from being fed properly and affecting processing efficiency and quality. Second, the system lacks interference and drainage processes during the processing of the bar stock and spherical beads, affecting the quality of the cylindrical processing. Third, the layout of the device is not reasonable enough, making the structure not compact. Summary of the Invention

[0020] Furthermore, the inner side of the sealing plate is provided with sound-absorbing sponge.

[0021] Furthermore, the chassis is equipped with electronic control components, and a controller is also installed on the top surface of the chassis.

[0022] Furthermore, the round bar conveying device includes a round bar receiving device and a round bar clamping device;

[0023] The round bar receiving device is located at the output port of the square bar rounding device and is used to receive round bars;

[0024] The round bar clamping device is used to transport the round bar from the round bar receiving device to the round bar inlet of the round bar pressing device.

This improves processing efficiency while ensuring the processing quality of the bar stock. The lower working platform is used for ball stock processing. On the one hand, it allows for a reasonable allocation of the layout of various devices in the processing system, avoiding excessive occupation of the longitudinal space of the factory. On the other hand, the balls processed by the bar stock pressing device can also enter the ball stock vibration drying device by gravity, making it easier for the ball stock vibration drying device to receive the balls. That is, the bar stock is transported horizontally, and the balls are transported mainly by gravity. This improves the transport efficiency and simplifies the structure of the transport device while ensuring the stability of both transport. Furthermore, layering the bar stock and ball stock processing also facilitates the separate control, monitoring, and maintenance of the bar stock processing and the ball stock processing.

[0059] As attached Figure 1 -Appendix Figure 21 As shown, the present invention provides an automated ball processing system, including a frame 8, a bar stock processing line and a ball processing line;

[0060] Reference Appendix Figure 2 The frame 8 includes an upper working platform 81 and a lower working platform 82;

[0061] Reference Appendix Figure 1 The bar processing line includes a square bar feeding device 1, a square bar rounding device 2, a round bar conveying device, and a round bar bead pressing device 5 arranged linearly on the upper working platform 81. The bar 10 is processed into round beads after passing through the bar processing line. The bar 10 is always located on the same vertical plane of the frame 8 during the conveying process of the bar processing line. In a preferred embodiment, the bar 10 is always located on the longitudinal vertical plane of the frame 8 during the conveying process of the bar processing line. This eliminates the need for a lateral displacement adjustment mechanism for the square bar feeding device 1, the square bar rounding device 2, the round bar conveying device, and the round bar bead pressing device 5, which greatly simplifies the structure of the processing system. Moreover, the bar 10 is conveyed horizontally and longitudinally on the bar processing line. Compared with the longitudinal conveying method of the bar 10 in the existing conventional round bead automated processing system, the transport of the bar 10 is more precise, and the processing is more reliable and efficient. This improves the processing efficiency while ensuring the processing quality of the bar 10.

[0062] The ball processing line includes a ball vibration drying device 6 and a ball drilling device 7 set on the lower working platform 82. The ball vibration drying device 6 receives the balls processed by the round bar pressing device 5 and dries them, and then conveys them to the ball drilling device 7 for drilling.

[0063] This invention arranges the bar stock processing line and the ball stock processing line of the automated ball bearing processing system in a layered layout. The upper working platform 81 is used for processing the bar stock 10, and the bar stock 10 is always transported and processed in one direction on the upper working platform 81, making the transport of the bar stock 10 more precise and the processing more reliable and efficient. Thus, while ensuring the processing quality of the bar stock 10, the processing efficiency is improved. The lower working platform 82 is used for ball stock processing. On the one hand, this allows for a reasonable allocation of the layout of various devices in the processing system, and can avoid the processing system occupying too much space in the factory. The longitudinal and transverse spaces of the room; on the other hand, the round beads processed by the round bar pressing device 5 can also enter the round bead vibration drying device 6 by gravity, which makes it easier for the round bead vibration drying device 6 to receive the round beads. That is, the conveying of the bar material is horizontal, and the conveying of the round beads is mainly by gravity. In this way, the conveying efficiency is improved and the structure of the conveying device is simplified while ensuring the conveying stability of both. Furthermore, the processing of the bar material 10 and the round beads are separated into layers, which also makes it easier to control, monitor and maintain the processing of the bar material 10 separately, and also makes it easier to control, monitor and maintain the processing of the round beads separately.

[0064] Reference Appendix Figure 4 -Appendix Figure 9In one embodiment, the square bar feeding device 1 is used for feeding square bars. In specific use, multiple bars 10 are initially stacked in parallel with each other. For example, the bars arranged in bundles are directly untied in the hopper 11, and then the square bar feeding device 1 feeds multiple bars 10 one after another along a specific path, and the bars 10 are transported to the square bar rounding device 2 for rounding processing.

[0065] The square bar feeding device 1 includes a hopper 11 and a bar conveying mechanism 12. Both the hopper 11 and the bar conveying mechanism 12 are mounted on a support frame 14. In a preferred embodiment, the support frame 14 is mounted on a housing 85, or the support frame 14 can be used directly as the housing frame of the housing 85. The hopper 11 is used to hold multiple square bars to be fed, and the bar conveying mechanism 12 is used to convey the square bars one by one to the square bar rounding device 2.

[0066] The bar conveying mechanism 12 includes a conveying track 121 and a pushing mechanism 122. One end of the conveying track 121 is a pushing end 1211, and the other end is a pushing end 1212. The output end of the pushing mechanism 122 reciprocates from the pushing end 1211 to the pushing end 1212. When the output end of the pushing mechanism 122 moves toward the pushing end 1212, the output end of the pushing mechanism 122 pushes the bar 10 located in the conveying track 121 out of the pushing end 1212, so that the square bar enters the next station, specifically, so that the square bar enters the square bar rounding device 2. When the output end of the pushing mechanism 122 moves toward the pushing end 1211, the output end of the pushing mechanism 122 exits the conveying track 121 so that the next square bar can enter the conveying track 121 for the next pushing.

[0067] The bottom of the hopper 11 is provided with a material drop chute 118, which is aligned with the conveying track 121. Multiple square bars located in the hopper 11 fall into the conveying track 121 one by one through the material drop chute 118, thereby realizing the feeding of square bars one by one.

[0068] In this square bar feeding device 1, multiple square bars to be fed only need to be stacked in the same direction in the hopper 11. The multiple square bars in the hopper 11 fall one by one into the conveying track 121. Then, the pushing mechanism 122 conveys the single square bars located in the conveying track 121 to the square bar rounding device 2 one by one, thus completing the loading of the square bars. The square bars move under the guidance of the conveying track 121 and can enter the square bar rounding device 2 accurately and quickly. The feeding effect is good and the efficiency is high. Moreover, the overall structure of the square bar feeding device 1 is simple and reliable.

[0069] Preferably, the hopper 11 includes a high upright plate 111, an inclined plate 112, a low upright plate 113, and two oppositely arranged side plates 114. The high upright plate 111, the inclined plate 112, the low upright plate 113, and the two side plates 114 enclose each other to form the hopper 11. The inner sides of the high upright plate 111, the inclined plate 112, the low upright plate 113, and the two side plates 114 enclose each other to form a hopper cavity.

[0070] The tall upright plate 111 and the short upright plate 113 are arranged opposite to each other and enclose each other to form the material drop trough 118. The width of the material drop trough 118 is preferably greater than the cross-sectional dimension of one square bar and less than the cross-sectional dimension of two square bars, that is, only one material drop trough 118 falls into the conveying track 121 at a time. In this embodiment, the bottom of the material drop trough 118 is a part of the conveying track 121. In specific use, the square bar feeding device 1 also includes a support frame 14. The hopper 11 and the bar conveying mechanism 12 are both set on the support frame 14. At this time, the upper surface of the support frame 14 is the bottom surface of the material drop trough 118. The tall upright plate 111, the short upright plate 113 and the upper surface of the support frame 14 enclose each other to form the conveying track 121.

[0071] The lower end of the inclined plate 112 is fixedly connected to the upper end of the short upright plate 113, thereby guiding multiple square bars located in the hopper cavity to fall into the material drop trough 118 by gravity without the need for other driving mechanisms, simplifying the structure of the square bar feeding device 1.

[0072] The high plate 111, the inclined plate 112 and the low plate 113 are arranged between the two side plates 114. The two side plates 114 can prevent multiple square bars from sliding out on the left and right sides of the hopper 11, and can also ensure that the multiple square bars are aligned, so that the position of the square bars falling into the conveying track 121 is determined.

[0073] Preferably, the longitudinal direction of the discharge trough 118 can accommodate multiple square bars, that is, the height of the discharge trough 118 is higher than the cross-sectional dimensions of at least two square bars. At this time, the discharge trough 118 can accommodate multiple square bars vertically, and the multiple bars 10 are arranged sequentially. When the square bar on the conveying track 121 is pushed out of the push end 1212 by the output end of the push mechanism 122, and the output end of the push mechanism 122 is reset back to the push end 1211, the upper square bar falls directly into the conveying track 121, and the next square bar can be conveyed directly, thereby improving the conveying efficiency and reliability of the square bars.

[0074] Reference Appendix Figure 3 Preferably, the hopper 11 further includes a limiting mechanism 115, which can be used to limit the square bars in the hopper 11 from falling into the discharge trough 118 to stop the feeding of square bars, and can also be used to prevent the square bars located in the hopper cavity from getting blocked or stuck.

[0075] The low upright plate 113 is provided with a sliding groove 1131, the lower end of the inclined plate 112 is provided with an opening groove 1121, and the limiting mechanism 115 includes a lifting drive component I 1151 and a limiting plate 1152 provided on the output end of the lifting drive component I 1151.

[0076] The lifting drive component I 1151 drives the limiting plate 1152 to rise and fall within the sliding groove 1131. When the limiting plate 1152 rises, it extends out of the lower end of the inclined plate 112 through the opening groove 1121, thus providing the limiting plate 1152 to the lower end of the inclined plate 112. At this time, the square bars located in the hopper cavity can no longer fall into the discharge chute 118 through the inclined plate 112. The feeding operation ends after all the square bars in the discharge chute 118 have been fed. In this embodiment, the limiting mechanism 115 can also restore the flow of the blocked or stuck bars 10 by raising and lowering the limiting plate 1152 when multiple square bars are blocked or stuck in the hopper cavity, ensuring feeding stability.

[0077] Preferably, the hopper 11 further includes a material blocking mechanism 116, which is used to block the material discharge chute 118 and restrict the square bar from continuing to fall into the material discharge chute 118, so as to stop the feeding of the square bar.

[0078] The material blocking mechanism 116 includes a linear drive component III 1161 and a material blocking plate 1162 disposed on the output end of the linear drive component III 1161;

[0079] The high plate 111 or the low plate 113 is provided with a baffle groove 1111 in the middle or upper part of the discharge trough 118. In a preferred embodiment, the baffle groove 1111 is provided in the middle of the high plate 111. The linear drive member III 1161 drives the baffle plate 1162 to extend into the discharge trough 118 through the baffle groove 1111 to block the discharge trough 118 and prevent the square bar located in the bucket cavity from falling into the discharge trough 118 again.

[0080] Preferably, the hopper 11 further includes a shaking mechanism 117, which is used to shake the square bars located in the hopper cavity, especially the square bars located at the opening of the discharge chute 118, so as to avoid the square bars in the hopper cavity from being blocked or stuck.

[0081] The material shaking mechanism 117 includes a motor 1171 and a material shaking disk 1172. The motor 1171 is located at the end of the high plate 111 away from the hopper cavity, and the material shaking disk 1172 is located on the output shaft of the motor 1171.

[0082] The high plate 111 has a longitudinally arranged slot 1112. The shaking disc 1172 extends into the hopper cavity through the slot 1112, thereby actuating the square bar near the slot 1112 and moving the square bar to avoid the problem of the square bar getting stuck in the hopper cavity.

[0083] Preferably, the conveying track 121 further includes an outer conveying track 1213 disposed outside the hopper 11, and the upper end of the outer conveying track 1213 has an opening 1214, and the outer conveying track 1213 and the conveying track 121 at the bottom of the material drop chute 118 are interconnected. By setting the outer conveying track 1213, it is convenient for staff to directly observe the feeding situation and judge the feeding status.

[0084] Preferably, the square bar feeding device 1 further includes a pressing and pushing mechanism 13, which is used to press the square bar into the outer conveying track 1213 and follow the square bar along the outer conveying track 1213 until the square bar moves out of the push-out end 1212 at the end of the outer conveying track 1213.

[0085] The pressing and pushing mechanism 13 includes a linear drive II 131, a lifting drive II 132, and a pressing block 133. The pressing block 133 is disposed at the output end of the lifting drive II 132, which drives the pressing block 133 to move toward the opening 1214. The lifting drive II 132 is disposed at the output end of the linear drive II 131, which drives the pressing block 133 to move along the outer conveying track 1213. Preferably, the pressing block 133 blocks the opening 1214, thereby preventing the square rod from being ejected from the opening 1214. In another embodiment, a portion of the pressing block 133 blocks the opening 1214, while another portion extends into the outer conveying track 1213. This not only prevents the square rod from being ejected from the opening 1214 but also pushes the square rod to move along the outer conveying track 1213, thus supplementing the pushing mechanism 122.

[0086] Preferably, the ejector end 1212 is connected to the square bar grinding device 2, which is used to grind the square bar into a round bar. That is, when the square bar is inserted into the ejector end 1212, the square bar directly enters the square bar grinding device 2 for grinding. At this time, part of the square bar is located on the outer conveying track 1213, and another part enters the square bar grinding device 2. The square bar is driven to rotate by the square bar grinding device 2. In this embodiment, the feeding path of the square bar is short, which can improve the working efficiency. Moreover, by setting the outer conveying track 1213, the rotating square bar can be prevented from affecting the bar material located in the dropping trough 118. By setting the pressing and pushing mechanism 13, the square bar can be prevented from shaking out from the opening 1214.

[0087] Preferably, the pushing mechanism 122 includes a linear drive I 1221 and a push rod 1222. The push rod 1222 is disposed on the output end of the linear drive I 1221, that is, the push rod 1222 is used as the output end of the pushing mechanism 122. The linear drive I 1221 drives the push rod 1222 to move along the bottom of the conveying track 121. In a preferred embodiment, the linear drive I 1221 is a linear module, and two position sensors 1223 are provided on the base of the linear module for controlling the push rod 1222 to fully push out the square bar and to fully reset the push rod 1222. In addition, a limiting rod 1224 can be provided on the slider (output end of the linear module) facing the side plate 114 of the hopper 11 to limit the movement limit position of the slider.

[0088] Among them, linear drive I 1221, linear drive II 131, linear drive III 1161, lifting drive I 1151 and lifting drive II 132 can all be cylinders, hydraulic cylinders or linear modules. In a preferred embodiment, linear drive I 1221 and linear drive II 131 are both linear modules and are arranged parallel to the direction of the conveying track 121 to ensure the stroke length of the linear drive.

[0089] Reference Appendix Figure 10 -Appendix Figure 14 In one embodiment, the square bar rounding device 2 includes a bar carrying mechanism 22 and a square bar rounding mechanism 23, wherein the bar carrying mechanism 22 and the square bar rounding mechanism 23 are both mounted on a support 21, the support 21 is mounted on an upper working platform 81, the bar carrying mechanism 22 is used to carry the bar 10, and the square bar rounding mechanism 23 is used to round the square bar.

[0090] The square bar grinding mechanism 23 includes a rotary drive device 232 and two grinding wheels 231. The axes of the two grinding wheels 231 are parallel to each other, and the wheel body spacing of the two grinding wheels 231 is smaller than the diameter of the bar to be ground. The rotary drive device 232 drives at least one of the grinding wheels 231 to rotate. Preferably, the rotary drive device 232 drives the two grinding wheels 231 to rotate in opposite directions.

[0091] The bar stock carrying mechanism 22 includes a carrying track 221, which is arranged between two grinding wheels 231. The carrying surface of the carrying track 221 faces the gap between the two grinding wheels 231. When a square bar is placed on the carrying surface of the carrying track 221, the side of the square bar abuts against the two grinding wheels 231. During the rotation of the grinding wheels 231, the side of the square bar is rounded. During the rounding process, the square bar will rotate with the grinding wheels 231 to ensure the roundness of the square bar.

[0092] This square bar grinding device 2 differs from the conventional method of placing the square bar directly from the top of two grinding wheels 231 and grinding it by gravity. In this method, the interval between the two grinding wheels 231 does not need to be adjusted, resulting in higher grinding efficiency and better quality. Furthermore, the two grinding wheels 231 can be installed in a fixed manner, which is simple and reliable, reduces the maintenance frequency of the device, and extends its service life.

[0093] Preferably, the bar stock carrying mechanism 22 further includes a position adjustment mechanism 222, which is used to adjust the distance between the carrying track 221 and the two grinding wheels 231. In this embodiment, the distance between the carrying track 221 and the two grinding wheels 231 can be adjusted by the position adjustment mechanism 222. By adjusting the distance between the carrying track 221 and the two grinding wheels 231, it can be used to adapt to the grinding of square bars of different sizes, and the diameter of the rounded bar can also be adjusted.

[0094] Preferably, the two ends of the bearing track 221 extend beyond the two ends of the grinding wheels 231;

[0095] The position adjustment mechanism 222 includes a linear movement mechanism 2221 and two vertical connecting plates 2222 disposed on the output end of the linear movement mechanism 2221. The other end of the vertical connecting plate 2222 is connected to the end of the bearing rail 221. That is, the two vertical connecting plates 2222 and the bearing rail 221 form a "U" shaped structure, which can ensure that the two ends of the bearing rail 221 move synchronously and improve the structural strength of the bearing rail 221. In this embodiment, the bearing rail 221 is indirectly disposed on the support 21 through the linear movement mechanism 2221.

[0096] The linear moving mechanism 2221 moves in a direction perpendicular to the plane containing the axes of the two grinding wheels 231, thereby ensuring that the linear moving mechanism 2221 drives the bearing track 221 to always move perpendicularly toward the plane containing the axes of the two grinding wheels 231, so that the roundness of the bar stock is consistent in all directions.

[0097] The linear motion mechanism 2221 can be manually or automatically depending on actual needs. For example, it can be driven by various linear drive methods such as cylinders, hydraulic cylinders, linear modules, and lead screw nut pairs. Preferably, it can be driven by a linear drive method with position locking, so that the bearing rail 221 can be kept in the set position.

[0098] Preferably, mounting blocks 2213 are provided at both ends of the bearing track 221, and the vertical connecting plate 2222 is fixedly connected to the mounting blocks 2213. That is, the bearing track 221 has an "I" shaped structure, which can ensure that the bearing track 221 has a small range within the two grinding wheels 231 and will not contact the grinding wheels 231, while the position at both ends of the bearing track 221 that extends out of the two grinding wheels 231 is large, which improves the connection strength with the vertical connecting plate 2222.

[0099] Preferably, the two ends of the carrying track 221 are a square bar entry end 2211 and a round bar output end 2212, respectively. In this embodiment, the bar stock can be directly fed and discharged along the axial direction of the grinding wheel 231 via the carrying track 221, that is, the movement and conveying of the bar stock is realized during the rounding process of the square bar. This allows the rounded bar stock 10 to be conveniently conveyed directly to the round bar receiving device 3 in the axial direction of the bar stock 10, making the conveying of the bar stock simpler and more reliable, and facilitating the direct conveying or processing of the bar stock to the next process.

[0100] Preferably, the square bar rounding device further includes a bar moving mechanism, which is used to push the bar from the square bar entry end 2211 into the bearing track 221 and push it out from the round bar output end 2212 into the bearing track 221. In this embodiment, one end of the square bar enters the bearing track 221 from the square bar entry end 2211, and the part that enters immediately contacts the two grinding wheels 231 and performs a rounding operation. As the bar moving mechanism continues to push the bar into the bearing track 221, the newly pushed part is rounded accordingly. Thus, the rounding of the square bar is performed sequentially from one end to the other. On the one hand, this can reduce the burden on the square bar rounding mechanism 23. On the other hand, it can also ensure that every part of the square bar is rounded by passing through the entire length of the grinding wheel 231, which can improve the rounding effect of the bar. In an embodiment with a vertical connecting plate 2222, a square through hole 22221 is provided on the vertical connecting plate 2222. The mounting block 2213 is fixedly installed at the bottom of the through hole 22221 by fasteners, while the other parts of the through hole 22221 are used as the square bar inlet end 2211 and the round bar outlet end 2212.

[0101] Preferably, a round bar receiving device 3 is provided downstream of the square bar rounding device 2. The round bar receiving device 3 is connected to the round bar output end 2212, so that it can directly carry the rounded bar material 10, so that the round bar can be clamped and transported by the round bar clamping device 4.

[0102] Preferably, the two grinding wheels 231 are an alloy grinding wheel and a silicone wheel, respectively, which can ensure the processing effect.

[0103] Preferably, the wheel body spacing of the two grinding wheels 231 is zero, that is, the two grinding wheels 231 are tangentially arranged. At this time, the two grinding wheels 231 rotate in opposite directions. In this embodiment, the two grinding wheels 231 can grind the smallest size round bar, and there will be no situation where grinding cannot continue when the size of the round bar is smaller than the spacing distance.

[0104] Preferably, the square bar rounding device further includes a spraying mechanism I25 disposed above the wheel body gap of the two rounding wheels 231, which is used to spray water on the two rounding wheels 231. On the one hand, it cools down the rounding wheels 231 to ensure the temperature, and on the other hand, it can prevent the debris of the bar 10 from floating in the support 21 and avoid dust.

[0105] Reference Appendix Figure 15 -Appendix Figure 17 In one embodiment, the bar conveying device includes a round bar receiving device 3 and a round bar clamping device 4, wherein the round bar receiving device 3 is used to receive the round bars conveyed from the square bar rounding device 2, and the round bar clamping device 4 is used to convey the round bars to the round bar bead pressing device 5 for bead processing.

[0106] The round rod receiving device 3 includes a round rod placement cavity 33 formed by a base plate 31 and two side plates 32. The two side plates 32 are vertically arranged on the base plate 31 and are arranged opposite to each other, making the round rod placement cavity 33 a rectangular cavity with an opening at the top. The round rod is received by the base plate 31 and limited by the two side plates 32. The round rod placement cavity 33 can stably and reliably place the round rod. The two side plates 32 are provided with notches 321 that communicate with the round rod placement cavity 33 at opposite positions. The notches 321 are slots opened from the top of the side plates 32 downwards. The slots can be a certain distance away from the base plate 31 or can directly penetrate the entire side plate 32 to the base plate 31. When penetrating the side plate 32, one side plate 32 is divided into multiple independent plates.

[0107] The round bar receiving device 3 also includes an end plate 34, which is located at one end of the round bar placement cavity 33. This allows for easy alignment of one end of the round bar placed in the round bar placement cavity 33. Specifically, when the round bar is placed in the round bar placement cavity 33, one end of it abuts against the end plate 34, thereby limiting the position of the end of the round bar and facilitating the round bar clamping device 4 to clamp the round bar at the set position.

[0108] The side plate 32 has a spacer slot 35 between it and the end plate 34; it also includes a round bar detection sensor 36, which detects whether there is a round bar in the round bar placement cavity 33 through the spacer slot 35. At this time, by setting the spacer slot 35 and the round bar detection sensor 36, it is very convenient to check whether there is a round bar in the round bar placement cavity 33. In a specific embodiment, the round bar detection sensor 36 can be a photoelectric switch.

[0109] The round bar clamping device 4 includes a moving mechanism 41 and a gripper manipulator 42 disposed at the output end of the moving mechanism 41. The moving mechanism 41 is used to drive the gripper manipulator 42 to move, thereby moving the gripper manipulator 42 to the round bar receiving device 3 to clamp the round bar in the round bar placement cavity 33, and to the round bar pressing bead device 5 to put down the round bar. The gripper 421 of the gripper manipulator 42 clamps the round bar through the notch 321, that is, the physical body of the gripper 421 extends into the round bar placement cavity 33 through the notch 321, avoiding interference from the side plate 32 of the round bar placement cavity 33 to the extension of the gripper 421, so that the gripper 421 can directly clamp the round bar laterally, thereby improving the success rate and stability of the round bar clamping.

[0110] In this round bar conveying system, the round bar placement cavity 33 can stably place round bars, while the round bar clamping device 4 can easily and stably clamp the round bars placed inside the round bar placement cavity 33 through the notch 321 on the side plate 32, resulting in a high success rate of round bar clamping. Moreover, the swing direction of the round bars can be directly adjusted through clamping, thus eliminating the need for orientation adjustment of the round bars entering the round bar placement cavity 33, simplifying the complexity of the round bar clamping device 4, and facilitating the round bar clamping device 4 to ensure that the round bars are oriented in the correct direction during the clamping process, thereby facilitating the conveying of the clamped round bars to the round bar pressing bead device 5. In addition, the arrangement of the end plate 34, the spacer slot 35, and the round bar detection sensor 36 facilitates the position restriction of the round bars and the detection of the presence of round bars, thereby improving the efficiency and effectiveness of round bar conveying.

[0111] Preferably, n sets of notches 321 are arranged parallel to the length direction of the round bar placement cavity 33;

[0112] The gripper manipulators 42 are arranged in n parallel groups;

[0113] n≥2, n sets of notches 321 and n sets of gripper manipulators 42 correspond one-to-one.

[0114] In a preferred embodiment, n=2. In this case, only two sets of notches 321 and gripper manipulators 42 are required, which simplifies the structure. At the same time, the two sets of gripper manipulators 42 can hold the round bar at two positions along the length of the round bar. This can ensure that the orientation of the round bar is parallel to the length of the round bar placement cavity 33 while holding the round bar, further improving the stability of the round bar clamping and ensuring the orientation of the round bar during clamping.

[0115] Preferably, the interval between two adjacent sets of notches 321 is less than the length of the round rod. In this embodiment, after the round rod is placed in the round rod placement cavity 33, its body is on the two sets of notches 321 so that at least two adjacent sets of gripper robots 42 can grip different positions of the same round rod.

[0116] Preferably, the round bar receiving device 3 further includes a top plate 37, which is disposed on the side of the two side plates 32 away from the end plate 34. The distance between the end of the top plate 37 and the end plate 34 should be greater than the length of the round bar, so that the round bar can be easily moved out of the round bar placement cavity 33 from the position without the top plate 37.

[0117] The upper end of the top plate 37 is the first round bar input channel, and the end of the round bar placement cavity 33 is the second round bar input channel 38. That is, the upper end of the top plate 37 can be used to receive round bars, and the entrance of the round bar placement cavity 33 below the top plate 37 can also be used to receive round bars.

[0118] Preferably, the moving mechanism 41 includes a horizontal moving component 411 and a vertical moving component 412 disposed at the output end of the horizontal moving component 411, and the gripper robot 42 is disposed on the output end of the vertical moving component 412.

[0119] The vertical moving component 412 drives the gripper robot 42 to move along the depth direction of the round bar placement cavity 33 to grip the round bar from the round bar placement cavity 33, while the horizontal moving component 411 is used to move the round bar to the next process.

[0120] Preferably, the moving mechanism 41 further includes a gripper mounting plate disposed on the output end of the vertical moving component 412. When n sets of gripper manipulators 42 are provided, the n sets of gripper manipulators 42 are arranged in parallel on the gripper mounting plate, so that one vertical moving component 412 can drive multiple gripper manipulators 42 to move synchronously at one time, ensuring the synchronization rate of multiple gripper manipulators 42.

[0121] Preferably, the gripper robot 42 includes a finger cylinder 422 and grippers 421 disposed on the two output ends of the finger cylinder 422. The gripper robot 42 provided in this embodiment has a simple structure and is convenient and quick to control.

[0122] Preferably, the gripper 421 has a fitting groove 4211 on the opposite side of the gripping part to fit with the cross section of the round bar, so as to improve the stability of the gripper 421 in grasping the round bar.

[0123] In one embodiment, the round bar bead pressing device 5 includes a bead pressing wheel and a pressure wheel arranged in a pair of rollers, a distance adjustment component for driving the bead pressing wheel and pressure wheel II to move away from each other, and a rotary drive component for driving the bead pressing wheel and / or pressure wheel II to rotate. The area above the bead pressing wheel and pressure wheel is a round bar inlet 51, and the area below the bead pressing wheel and pressure wheel is a round bead outlet 52. A spraying mechanism II 53 is also provided above the bead pressing wheel and pressure wheel. Furthermore, the round bar bead pressing device 5 is mounted on an upper working platform 81. In actual use, the round bar clamping device 4 clamps the round bar above the round bar inlet 51 and then releases it, allowing the round bar to fall into the round bar inlet 51 and be ground into beads. The ground beads finally flow into the round bead vibration drying device 6 through the round bead outlet 52.

[0124] Reference Appendix Figure 18 -Appendix Figure 21 In one embodiment, the ball vibration drying device 6 is used to dry the water-laden balls. Specifically, it is used to transport and dry the balls that have just been processed from the round bar pressing device 5. At this time, since the round bar pressing device 5 is equipped with a spray mechanism II 53, the balls processed by the round bar pressing device 5 are wet and have water stains. The ball vibration drying device 6 is used to dry the balls and transport them to the ball drilling device 7. That is, the ball vibration drying device 6 serves as both a drying device and a conveying device from the round bar pressing device 5 to the ball drilling device 7.

[0125] The ball vibration drying device 6 includes a vibration channel 61, a conveying channel 62, a vibration mechanism 63, and a first drying mechanism 64; in actual use, the ball vibration drying device 6 also includes a bracket 67 for mounting the various components, which is set on the lower working platform 82.

[0126] The vibration channel 61 includes a mesh plate 611 arranged inclined in the horizontal direction and side baffles 612 arranged on both sides of the mesh plate 611. The mesh plate 611 and the side baffles 612 are combined to form a channel. The ball discharge port 52 of the round bar pressing device 5 conveys the ball to the top of the mesh plate 611. The ball rolls down the mesh plate 611 by gravity. At this time, the two side baffles 612 restrict the ball from rolling out of the side baffles 612 of the mesh plate 611. The vibration mechanism 63 drives the mesh plate 611 to vibrate, which can shake off the water stains on the ball and prevent the ball from staying on the mesh plate 611 without rolling down, thus ensuring the conveying effect of the ball.

[0127] One end of the conveying channel 62 is connected to the lower end of the mesh plate 611, and the other end is used to convey the beads to the next station. That is, the conveying channel 62 is used to receive the beads that have been filtered and dried once on the mesh plate 611 and convey the beads to the next station. The conveying channel 62 is fixedly set on the bracket 67, so it is always in a static state. At this time, the stability of conveying the beads to the next station can be improved, and the jumping of the beads can be avoided, which would increase the difficulty of conveying.

[0128] The first drying mechanism 64 acts on the vibration channel 61 to dry the beads passing through the vibration channel 61. The first drying mechanism 64 and the vibrating mesh plate 611 work together to improve the drying effect by heating and drying after the water stains are shaken off. On the other hand, the vibration of the beads improves the uniformity of contact between the surface of the beads and the first drying mechanism 64, further improving the drying effect.

[0129] This ball bearing vibration drying device 6 uses gravity to transport the balls, eliminating the need for a separate conveying device and simplifying the structure. The vibration channel 61 is equipped with a vibrating mesh plate 611, which not only shakes off water stains from the balls but also prevents them from remaining on the mesh plate 611 and rolling off, ensuring effective ball transport. The first drying mechanism 64 is positioned on the vibration channel 61. This allows for drying by heating after the water stains have been shaken off, improving the drying effect. Furthermore, the ball vibration increases the uniformity of contact between the ball surfaces and the first drying mechanism 64, further enhancing the drying effect. The vibration channel 61 connects to the conveying channel 62. Since the conveying channel 62 remains stationary, this improves the stability of the ball transport to the next station, preventing ball bouncing and increased transport difficulty.

[0130] Preferably, the mesh plate 611 and the conveying channel 62 are hinged, thereby connecting the mesh plate 611 and the conveying channel 62. This ensures that the balls rolling off the mesh plate 611 can smoothly enter the conveying channel 62, while also preventing the vibration of the mesh plate 611 from affecting the conveying channel 62.

[0131] Preferably, the first drying mechanism 64 includes a mounting plate 641 and a first heating element 642 arranged on the mounting plate 641;

[0132] The mounting plate 641 is fixed to the upper ends of the two side baffles 612. The mounting plate 641, the mesh plate 611 and the two side baffles 612 form a rectangular channel. The mounting plate 641 is spaced 643 away from the upper end of the mesh plate 611. That is, the upper end of the mesh plate 611 has a drop inlet for the ball to enter. That is, the ball outlet 52 of the round bar pressing device 5 directly drops into the vibration channel 61 through the drop inlet.

[0133] In this embodiment, multiple first heating tubes 642 are arranged at intervals along the width direction of the mounting plate 641 to improve the drying effect.

[0134] Preferably, the vibration mechanism 63 includes a first motor 631 and a connecting rod 632. One end of the connecting rod 632 is eccentrically connected to the output end of the first motor 631, and the other end is hinged to the vibration channel 61. The output end of the first motor 631, the connecting rod 632 and the vibration channel 61 constitute a crank-rocker mechanism, which drives the vibration channel 61 to rock, thereby causing the mesh plate 611 to vibrate.

[0135] Preferably, the ball vibration drying device 6 further includes a second drying mechanism 65 for secondary drying of the balls to ensure the drying effect. The second drying mechanism 65 includes a conical cylinder 651, a mesh plate cylinder 652, a drying cylinder 653, and a rotary drive mechanism 654.

[0136] The mesh plate cylinder 652 is fixedly connected to the large end of the conical cylinder 651. The conical cylinder 651 has a conical cross-section, with a large-diameter circular opening at the upper end and a small-diameter circular opening at the lower end. The lower end of the conical cylinder 651 is vertically downward. The beads enter from the upper end of the mesh plate cylinder 652 and exit from the lower end of the conical cylinder 651. The conical cylinder 651 is connected to the output end of the rotary drive mechanism 654. In specific installation, the conical cylinder 651 is rotatably mounted on the bracket 67 via bearings, while the rotary drive mechanism 654 is fixed on the bracket 67, driving the conical cylinder 651 and the mesh plate cylinder 651. The plate cylinder 652 rotates, causing the beads to adhere to the plate cylinder 652 through centrifugal force, and gradually fall out from the small end of the conical cylinder 651 to the next station. The drying cylinder 653 is located on the outside of the plate cylinder 652, thereby drying the plate cylinder 652 and the beads on it. The inner wall of the drying cylinder 653 and the outer wall of the plate cylinder 652 have a second gap 655. This second gap 655 can prevent the rotating plate cylinder 652 from hitting the inner wall of the drying cylinder 653, and can also allow the water stains to flow out. It should be noted that most of the water stains have been shaken off by the vibrating plate 611, the rest are dried by the first drying mechanism 64, a small part enters the second drying mechanism 65 with the beads and is thrown to the inner wall of the drying cylinder 653 by the plate cylinder 652 for evaporation, and finally a small part flows out through the second gap 655.

[0137] The other end of the conveying channel 62 is used to convey the beads into the mesh cylinder 652, that is, the other end of the conveying channel 62 extends into the upper circular opening of the mesh cylinder 652.

[0138] Preferably, the drying cylinder 653 includes a cylindrical heat-conducting frame 6531 and second heating tubes 6532 arranged in a ring array within the cylindrical heat-conducting frame 6531. The outer wall of the cylindrical heat-conducting frame 6531 is made of heat-insulating material to avoid heat waste and improve the heating effect inside the cylinder.

[0139] Preferably, the small end of the conical cylinder 651 is connected to a straight cylindrical portion 6511. This forms a cylindrical conveying channel, which facilitates the guiding input of the balls to the next workstation, such as the lifting mechanism 66.

[0140] Preferably, the second drying mechanism 65 further includes a switching mechanism 656 that can block and open the straight cylinder 6511, thereby enabling the release and retention of the beads inside the conical cylinder 651 and prolonging the drying effect.

[0141] Preferably, the rotary drive mechanism 654 includes a second motor 6541 and a synchronous belt assembly 6542;

[0142] One of the synchronous pulleys of the synchronous belt assembly 6542 is fixedly connected to the second motor 6541, and the other synchronous pulley is connected to the outer wall of the straight cylindrical part 6511, which is achieved by using the synchronous belt assembly 6542.

[0143] Preferably, the ball vibration drying device 6 further includes a lifting mechanism 66, which includes an inclined elevator 661 and a receiving hopper 662 at the bottom of the elevator 661. The receiving hopper 662 is aligned with the small end of the conical cylinder 651. This arrangement allows the dried balls to be lifted and transported to the ball drilling device 7.

[0144] In one embodiment, the ball drilling device 7 can adopt the wood bead feeding mechanism, wood bead clamping mechanism, wood bead drilling mechanism and synchronous drive mechanism in Chinese patent "CN115609693B-An Automated Processing System for Wood Beads", and the specific details will not be repeated here.

[0145] In one embodiment, the conveying track 121 on the square bar feeding device 1 for feeding the bar stock 10, the carrying track 221 on the square bar rounding device 2 for carrying the bar stock 10 conveyed from the conveying track 121, the round bar receiving device 3 in the round bar conveying device for carrying the round bar stock 10 rounded from the square bar rounding device 2, the gripper robot 42 on the round bar clamping device 4 in the round bar conveying device for clamping the bar stock 10 in the round bar placing cavity 33, and the round bar inlet 51 on the round bar pressing device 5 are all located in the same direction; that is, the bar stock 10 moves in the same direction on the same vertical plane during the conveying process, and the bar stock 10 only moves up and down in the gripper robot 42 and the round bar inlet 51 during the process from upstream to downstream. The conveying track 121, the bearing track 221, and the round bar placement cavity 33 are all axially aligned with the bar material 10 itself. This arrangement ensures accurate and reliable conveying of the bar material 10. Conventional bead processing systems, such as the wooden bar rounding device in Chinese patent "CN115609693B - An Automated Wooden Bead Processing System," rely on gravity to drop the wooden bars onto two sets of rollers during rounding and beading. This feeding method has several drawbacks. First, it makes it impossible to control the rounding efficiency of the square bars, thus limiting the overall processing efficiency. Second, the gravity-dropping process, especially during the rounding of square bars, can lead to issues where one end of the bar enters the roller first, followed by the other end, resulting in processing failure and requiring repositioning of the bar, further impacting efficiency. This invention eliminates these problems. The rounding operation of the square bars can be controlled simply by adjusting the movement speed of the bars, improving both processing efficiency and ensuring processing quality.

[0146] In one embodiment, the ball discharge port 52 of the round bar pressing device 5 extends from the bottom surface of the upper working platform 81 into the lower working platform 82, thereby making the processing of the balls take place in the lower working platform 82, and separating the processing of the bar stock 10 and the processing of the balls.

[0147] The vibration channel 61 of the ball vibration drying device 6 is aligned and connected with the ball discharge port 52. The vibration channel 61 is used to receive the freshly processed balls and transport them to the second drying mechanism 65. The vibration channel 61 is inclined and can be transported by the gravity of the balls. Moreover, the bottom of the vibration channel 61 is a mesh plate 611, and it also has a vibration mechanism 63 to drive the vibration channel 61 to vibrate, so as to drain the wooden balls transported through the vibration channel 61.

[0148] In one embodiment, the upper working platform 81 is provided with a water collection tank 83 located below the square bar grinding device 2 and the round bar pressing device 5. The bottom of the water collection tank 83 is connected to a sewage collection pipe 84. The water sprayed by the spray mechanism I 25 of the square bar grinding device 2 and the spray mechanism II 53 of the round bar pressing device 5 is collected through the water collection tank 83 and the sewage collection pipe 84 after cooling and dust removal of the square bar grinding device 2 and the round bar pressing device 5, so as to realize a unified sewage flow direction within the system and improve the overall workshop environment.

[0149] In one embodiment, the rack 8 includes a chassis 85 and a frame 86 disposed on one side of the chassis 85, and the upper working platform 81 and the lower working platform 82 are disposed on the frame 86.

[0150] The top surface of the chassis 85 is located within the range of the upper working platform 81, and the square bar feeding device 1 is located on the top surface of the chassis 85, thereby enabling the square bar feeding device 1, the square bar rounding device 2, the round bar conveying device and the round bar pressing device 5 to work at the same height.

[0151] In this embodiment, the square bar feeding device 1 is set on the outside of the frame 86, so that other devices can be located in a relatively enclosed space inside the frame 86, ensuring the workshop environment.
