[0036] The cutting device with the nail hanging prevention function can better solve the technical problems of nail hanging phenomenon, equipment failure and production line stop in the process of automatic nail feeding in automatic assembly of parts.
[0037] The utility model provides a kind of cutting device with the nail hanging prevention function, refer to Figures 1 to 8 , the following will be described in detail with reference to the specific drawings.
[0038] As Figure 1 Indicated, the utility model relates to a kind of cutting device with the nail hanging prevention function, including cutting mechanism 1, feeding mechanism 2 and blowing mechanism 3.There is feed inlet 115 and discharge port 116 on cutting mechanism 1, feeding mechanism 2 is connected with feed inlet 115, blowing mechanism 3 is connected with discharge port 116.Feeding mechanism 2 is used to send screw into cutting mechanism 1 by feed inlet 115, blowing mechanism 3 is used to send screw out after screw enters blowing mechanism 3 by discharge port 116, and enter next production link.
[0039] Further, the cutting mechanism 1 comprises a housing 11 and a slider assembly 12. The feeding port 115 and the discharging port 116 are arranged on the housing 11. A sliding groove 117 is formed in the housing 11, and the slider assembly 12 is arranged in the sliding groove 117 of the housing 11.
[0040] More specifically, the housing 11 comprises a bottom plate 111, a first side wall 112, a second side wall 113 and a cover plate 114. The first side wall 112 and the second side wall 113 are arranged on two sides of the bottom plate 111, and the cover plate 114 is arranged on top of the first side wall 112 and the second side wall 113, so that the sliding groove 117 is formed in the housing 11. The cover plate 114 can press the slider assembly 12 arranged in the sliding groove 117 from above the first side wall 112 and the second side wall 113, so as to prevent the slider assembly 12 from shaking, but the relevant parts of the slider assembly 12 can slide in the sliding groove 117. The feeding port 115 is formed on the first side wall 112, and the discharging port 116 is formed on the bottom plate 111. In other words, the feeding mechanism 2 can feed the screws into the slider assembly 12 in the housing 11 from the side of the housing 11, and the slider assembly 12 moves the screws from the feeding port 115 to the discharging port 116, so that the screws fall into the blowing mechanism 3 from the discharging port 116 by their own gravity.
[0041] Please refer to Figure 2 , Figure 3 and Figures 7 to 9 , the slider assembly 12 further comprises a first slider 121, a second slider 122, a first blocking block 123, a second blocking block 124, a blocking structure and a power source 126. The first slider 121 is slidably arranged in the sliding groove 117. The second slider 122 is slidably arranged on the first slider 121 relative to the first slider 121 along the length direction of the sliding groove 117. A screw storage port 125 for storing screws is formed between the first slider 121 and the second slider 122. The first blocking block 123 moves with the first slider 121, specifically, is fixedly arranged opposite to the first slider 121, and the second slider 121 is fixedly arranged on the housing 11. The power source 126 drives the first slider 121 to move, thereby moving the screw storage port 125 from the feeding port 115 to the discharging port 116 (i.e. from the right side in Figures 7 to 9 to the left side), and the slider assembly 12 forms a first state (see Figure 7 ), a second state (see Figure 8 ) and a third state (see Figure 9). In the first state, the two sides of the nail storage port 125 are formed with overlapping surfaces 1251 for the screw to overlap, the first slider 121 drives the second slider 122 to move together; in the second state, the blocking structure blocks the second slider 122, and the first slider 121 continues to move; in the third state, the nail storage port 125 corresponds to the position of the discharge port 116, the side wall of the first blocking block 123 is at least flush with the side wall of the second slider 122 at the nail storage port 125, and the side wall of the second blocking block 124 is at least flush with the side wall of the first slider 121 at the nail storage port 125. The meaning of the above at least is that the projection of the side wall of the first blocking block 123 to the side where the second slider 122 is located will not fall inside the second slider 122, can fall inside the nail storage port 125, or coincide with the side wall of the second slider 122; the projection of the side wall of the second blocking block 124 to the side where the first slider 121 is located will not fall inside the first slider 121, can fall inside the nail storage port 125, or coincide with the side wall of the first slider 121.
[0042] In the present embodiment, when cutting is performed using the cutting device, the screw can enter the cutting mechanism 10 from the feeding port 115 and enter the nail storage port 125 between the first slider 121 and the second slider 122, at this time the top cap of the screw overlaps the overlapping surfaces 1251 on the two sides of the nail storage port; the power source 126 drives the first slider 121 to move from the feeding port 115 to the discharge port 116, and drives the second slider 122 to move in the same direction, at this time, since the first slider 121 and the second slider 122 are relatively stationary, the size of the nail storage port 125 will not change; during the movement, when the first slider 121 and the second slider 122 enter the second state, the blocking structure blocks the second slider 122, and the second slider 122 will not continue to move, while the first slider 121 continues to move, at this time, the width of the nail storage port 125 will gradually increase with the increase of the movement distance; when the first slider 121 and the second slider 122 enter the third state, the side wall of the first blocking block 123 is flush with the side wall of the second slider 122 at the nail storage port, and the side wall of the second blocking block 124 is flush with the side wall of the first slider 121 at the nail storage port 125, that is, the overlapping surfaces 1251 on the two sides of the nail storage port in the first state and the second state have been occupied by the first blocking block 123 and the second blocking block 124, and the screw can enter the discharge port 116 from the nail storage port 125.
[0043] In addition, in some embodiments, the screw can also have a gasket or flange surface, and the screw enters the cutting device from the feeding port 115 through the feeding mechanism 2, enters the nail storage port 125 between the first slider 121 and the second slider 122, and overlaps the overlapping surfaces 1251 on the two sides of the nail storage port through the gasket or flange surface of the screw.
[0044] In the embodiment, due to the arrangement of the first blocking block 123, the second blocking block 124, the first sliding block 121, the second sliding block 122 and the blocking mechanism, and the position limitation, the sliding block assembly 12 can normally pass through the screw storage opening 125 to store screws when in the first state, and the first blocking block 123 and the second blocking block 124 can occupy the original overlapping surfaces 1251 on both sides of the screw storage opening during the movement of the sliding block assembly 12, so that the screws can be prevented from adhering to the first blocking block 123 and the second blocking block 124, the screw hanging fault in the current screw feeding process is better solved, the continuous feeding of target screws is realized, and the stability is improved.
[0045] Further, please continue to refer to Figures 2 to 6 In the embodiment, the first sliding block 121 comprises a first bearing part 1211, a first connecting part 1212 and a first force applying part 1213. The first bearing part 1211 is connected with the first force applying part 1213 through the first connecting part 1212. That is, the first connecting part 1212 is arranged between the first bearing part 1211 and the first force applying part 1213. The second sliding block 122 comprises a second bearing part 1221 and a second connecting part 1222, and the second bearing part 1221 is connected with the second connecting part 1222. The screw storage opening 125 is formed between the first bearing part 1211 and the second bearing part 1221. A first accommodating groove 1214 recessed downward is arranged on the first connecting part 1212 along the length direction of the sliding groove 117, and the second connecting part 1222 is arranged in the first accommodating groove 1214, so that the second sliding block 122 is arranged on the first sliding block 121. The length of the first accommodating groove 1214 along the length direction of the sliding groove 117 is greater than the length of the second connecting part 1222 along the length direction, so that the second sliding block 122 is movably arranged on the first sliding block 121 relative to the first sliding block 121.
[0046] In other words, the second sliding block 122 is arranged on the first sliding block 121 by its own gravity. When the second sliding block 122 is not blocked, the first sliding block 121 will drive the second sliding block 122 to move together by the friction force generated by the gravity of the second sliding block 122 during the movement.
[0047] Please continue to refer to Figure 2 、 Figure 3 and Figure 5 A second accommodating groove 1215 is further arranged on the first connecting part 1212, and the first blocking block 123 is fixedly arranged in the second accommodating groove 1215, so that the first blocking block 123 can move with the first sliding block 121.
[0048] To make the side wall of the first blocking block 123 flush with the side wall of the second sliding block 122 at the nail storage opening 125 in the third state, it is understood that the side wall of the first blocking block 123 and the side wall of the second bearing portion 1221 can be parallel planes. Similarly, the side wall of the second blocking block 124 and the side wall of the first bearing portion 1211 can also be parallel planes.
[0049] Further, please continue to refer to Figures 1 to 4 , Figure 6 and Figure 8 The blocking structure can be a guide groove 118 formed on the housing 11, specifically on the second side wall 113, and a guide portion 1223 is further formed on the second sliding block 122. The second connecting portion 1222 is arranged between the second bearing portion 1221 and the guide portion. When the sliding block assembly 12 is arranged in the housing 11, the guide portion 1223 extends into the guide groove 118. In the length direction of the sliding groove 117, the length of the guide groove 118 is greater than the length of the guide portion 1223, so that the guide portion 1223 can have a certain movement space in the guide groove 118, and when it moves to the tail of the guide groove 118, the side wall of the guide groove 118 prevents the second sliding block 122 from further moving.
[0050] That is, with the movement of the first sliding block 121, the second sliding block 122 will initially move with the first sliding block 121 under the action of friction, and the guide portion 1223 will also move in the length direction of the sliding groove 117 in the guide groove 118. When the guide portion 1223 moves to the end of the guide groove 118, the side wall of the guide groove 118 will block the guide portion 1223 to block the second sliding block 122 from continuing to move with the first sliding block 121. Since the length of the first accommodating groove 1214 is greater than that of the second connecting portion 1222, the stationary of the second sliding block 122 will not affect the continuous movement of the first sliding block 121, and the relative displacement between the first sliding block 121 and the second sliding block 122 occurs. Further, since the first sliding block 121 and the second sliding block 122 have a relative displacement, the distance between the first bearing portion 1211 and the second bearing portion 1221 changes, at this time, the width of the nail storage opening 125 continuously increases, and the side wall of the first blocking block 123 continuously approaches the side wall on the side of the second sliding block 122 at the nail storage opening, until they are flush.
[0051] Please continue to refer to Figure 1 and Figure 9The second blocking block 124 can be fixed on the shell 11, specifically on the cover plate 114. When the nail storage port 125 moves to a position corresponding to the discharge port 116, that is, in the third state, the side wall of the second blocking block 124 is flush with the side wall of the side where the first sliding block 121 is located. In other words, the second blocking block 124 is fixed during the entire movement, and the entire sliding block assembly 12 only limits the position of the second blocking block 124.
[0052] Please continue to refer to Figures 1 to 3 In the embodiment, the power source 126 can be a cylinder connected to the first force applying part 1213 of the first sliding block 121 through a telescopic rod to drive the first sliding block 121 to move. It can be understood that in other embodiments, the power source 126 can also be a motor.
[0053] In order to reset the first sliding block 121 and the second sliding block 122 and facilitate the next cutting, an elastic member 127, such as a spring, is arranged between the first sliding block 121 and the second sliding block 122. The elastic member 127 can be arranged in the first accommodating groove 1214 and located between the first connecting part 1211 and the second connecting part 1221. After the second sliding block 122 is stopped by the blocking structure, the elastic member 127 will store elastic potential energy through its own deformation as the first sliding block 121 moves. After the power source 126 drives the first sliding block 121 to reset, the elastic member 127 releases the elastic energy to make the second sliding block 122 slide in the first accommodating groove 1214 and then return to the initial state.
[0054] Further, please continue to refer to Figure 1 The feeding mechanism 2 can be two parallel arrangements, and a gap is formed in the middle of the material track 21, and a plurality of screws are arranged in a row in the gap. Through the vibration of the material track 21 or the pushing of the screws subsequently entering the material track, the screws are sent from the feeding port 115 into the cutting mechanism 1.
[0055] The blowing mechanism 3 includes a nail feeding pipe 32, a detection sensor 33, and an air injection port 31. One end of the nail feeding pipe 32 is connected to the discharge port 116. The detection sensor 33 is arranged in the nail feeding pipe 32 and is used for detecting the screws in the nail feeding pipe 32. The air injection port 31 is arranged on the wall of the nail feeding pipe 32. When the detection sensor 33 detects that the screw enters the nail feeding pipe 32, air is injected from the air injection port 31 to assist the movement of the screw in the nail feeding pipe 32.
[0056] The cutting device with the nail hanging prevention function specifically includes the following working processes:
[0057] Screw into position: the cylinder is in the cutting material preparation position, the storage nail port 125 is flush with the feeding port 115, the material rail 21 feeds the screw from the feeding port 115 into the cutting material device 12, and into the storage nail port 125 between the first slider 121 and the second slider 122, at this time the top cap of the screw overlaps the overlap surface 1251 on both sides of the storage nail port. After this step, the cutting mechanism 10 is in the first state, waiting for the downstream nailing signal;
[0058] Cutting action: after receiving the downstream nailing signal, the cylinder extends to drive the first slider 121 to move from the feeding port 115 to the discharging port 116, and drives the second slider 122 to move in the same direction. At this time, due to the friction between the first slider 121 and the second slider 122, or the combined action of friction and elastic element 127, the two are relatively stationary, so the size of the storage nail port 125 does not change; during the movement, when the first slider 121 and the second slider 122 enter the second state, the blocking structure blocks the second slider 122, and the second slider 122 no longer continues to move, while the first slider 121 continues to move, at this time the width of the storage nail port 125 will increase with the increase of the movement distance, and the elastic element 127 will deform and store elastic potential energy; when the first slider 121 and the second slider 122 enter the third state, the side wall of the first blocking block 123 is flush with the side wall of the second slider 122 at the storage nail port 125, and the side wall of the second blocking block 124 is flush with the side wall of the first slider 121 at the storage nail port 125, that is, the overlap surface 1251 on both sides of the storage nail port 125 has been occupied by the first blocking block 123 and the second blocking block 124, and the screw in the storage nail port 125 can enter the discharging port 116 under the action of gravity and continue to fall into the screw feeding pipe 32, at this time the first slider 121, the second slider 122, the first blocking block 123, the second blocking block 124 and the shell 11 form a closed channel, waiting for the detection sensor 33 to send a sensing signal;
[0059] Screw feeding: after the screw falls into the screw feeding pipe 32 and the detection sensor 33 detects the screw, a sensing signal is sent, and the airflow injection port 31 injects airflow to blow the target screw in the screw feeding pipe 32 to the next production link;
[0060] Cutting material reset: the cylinder retracts to move the first slider 121, the elastic element 127 releases the elastic potential energy, the slider assembly 12 moves from the third state to the second state, and the elastic potential energy of the elastic element 127 is completely released; the cylinder continues to drive the first slider 121 and the second slider 122 to move together, and then returns to the initial position, and the slider assembly 12 moves from the second state to the first state.
[0061] Fault description: after the cylinder extends, the detection sensor 33 does not send a sensing signal beyond the specified time, reporting a nailing fault, and the system alarms.
