Description

Technical Field

[0001] This invention belongs to the field of automated parts assembly technology, and particularly relates to a cutting device. Background Technology

[0002] Industrial automation technology is increasingly being applied to various fields as a core technology in modern enterprise production. In the automotive and other parts assembly industries, automated screw tightening technology is gradually replacing traditional manual tightening due to its reliability, efficiency, and traceability, effectively solving the problems of low efficiency and high workload in parts assembly.

[0003] In automated screw tightening technology, screws need to be cut (divided) by a screw cutting device to supply materials to subsequent devices according to the set production cycle.

[0004] This cutting device typically has two sliders that can move relative to each other, and a nail storage opening is formed between the two sliders. While pushing the two sliders to move, the position and size of the nail storage opening are changed.

[0005] During the cutting process, the feeding track neatly arranges the screws in a row. As needed downstream, the cutting mechanism within the cutting device separates the screws into individual pieces through a screw-holding opening between two sliders. At this point, the width of the screw-holding opening is relatively small to allow the screw to be supported within it. Then, by moving the sliders, the screw-holding opening containing the screw is moved above the screw-feeding tube. During this movement, due to the relative movement of the two sliders, the width of the screw-holding opening increases, exceeding the maximum width of the screw. The screw then falls into the screw-feeding tube channel under its own weight. The feed tube sensor detects the screw passing through, and high-pressure gas is then blown to the next stage.

[0006] However, in actual production, because screw types vary, the diameter of the screw shaft, the diameter of the flange on the top of the screw, and the height of the flange may all differ. To accommodate different screw types, components within the cutting device, such as the slider and the top cover, need to be replaced.

[0007] However, the above method requires the design of many replacement parts for a single cutting device, such as various sliders and top covers, which increases the cost. Summary of the Invention

[0008] The purpose of this invention is to provide a cutting device that can adapt to various screw specifications, avoiding the need to replace parts and reducing costs.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention proposes a cutting device, including a cutting mechanism comprising a housing and a cutting assembly. A groove is formed within the housing. The cutting assembly includes a first slider, a second slider, a blocking portion, a first spacing adjustment mechanism, and a second spacing adjustment mechanism. The first slider is slidably disposed within the groove. The second slider is connected to the first slider. A screw storage opening for storing screws is formed between the first and second sliders. When not blocked, the second slider follows the first slider. The blocking portion is disposed within the housing. After the second slider slides a set distance, the blocking portion prevents the second slider from continuing to move while allowing the first slider to move. The first spacing adjustment mechanism is disposed between the first and second sliders to adjust the width of the screw storage opening at the feed inlet. The second spacing adjustment mechanism is disposed between the second slider and the blocking portion to adjust the distance the second slider can move with the first slider.

[0010] Furthermore, the first slider has a first bearing portion, a first connecting portion and a first force-applying portion formed thereon. The first bearing portion is connected to the first force-applying portion through the first connecting portion. The second slider includes a second bearing portion and a second connecting portion. The second bearing portion is connected to the second connecting portion. The nail storage opening is formed between the first bearing portion and the second bearing portion.

[0011] Furthermore, the first connecting portion forms a downwardly recessed first receiving groove, and the second connecting portion is disposed in the first receiving groove so that the second slider rests on the first slider. The length of the first receiving groove along the length direction of the slide is greater than the length of the second connecting portion along that direction. The second slider rests on the first slider, and the second slider can move with the first slider when it is not blocked by the blocking portion.

[0012] Furthermore, the first adjustment mechanism is an adjustment bolt, which passes through the second connection part from the side of the second connection part away from the discharge port and abuts against the end face of the first receiving groove facing the discharge port.

[0013] Furthermore, the cutting mechanism also includes a power source, which is connected to the first force-applying part of the first slider to drive the first slider to move. A first elastic element is also provided between the first force-applying part and the second connecting part.

[0014] Furthermore, the blocking part is a blocking groove formed by the recess of the side wall of the housing, at least a portion of the second connecting part extends into the blocking groove, and the second spacing adjustment mechanism is an adjusting bolt, which passes through the second connecting part from the side away from the discharge port and protrudes toward the end of the blocking groove near the discharge port.

[0015] Furthermore, the cutting mechanism includes a third spacing adjustment mechanism, which is disposed between the first slider and the second slider to adjust the width of the nail storage opening when the nail storage opening is at the discharge port.

[0016] Furthermore, the third spacing adjustment mechanism is an adjustment bolt, which passes through the first force-applying part from the side of the first force-applying part away from the discharge port and protrudes in the direction of the second connecting part.

[0017] Furthermore, the first slider also includes a second receiving groove, a blocking block, and a fixing bolt. The position of the blocking block corresponds to the position of the feed port. A strip-shaped groove perpendicular to the length direction of the slide groove is formed on the blocking block. A connecting hole is formed in the second receiving groove. The fixing bolt passes through the strip-shaped groove and extends into the connecting hole to fix the blocking block in the second receiving groove.

[0018] Furthermore, the cutting device also includes a cover plate adjustment mechanism, which is disposed on the housing and connected to the cover plate to adjust the height of the cover plate covering the housing.

[0019] In summary, in this embodiment, by setting multiple spacing adjustment mechanisms on the cutting assembly, the width of the screw storage port at the feed inlet and the width of the screw storage port at the discharge outlet can be adjusted to adapt to the diameter of the screw shank and the flange diameter of various sizes of screws along the length of the chute. This avoids the need to replace parts and reduces costs.

[0020] Furthermore, the second receiving groove, the blocking block, and the fixing bolts can be used to accommodate the diameter of flanges with different types of screws in the width direction of the slide.

[0021] Furthermore, the cover plate adjustment mechanism allows for adaptation to the flange height of various screw types. Attached Figure Description

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setting," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] The purpose of this invention is to provide a cutting device that can adapt to various screw specifications, avoiding the need to replace parts and reducing costs.

[0043] like Figures 1 to 9 As shown, the cutting device provided in this embodiment of the invention includes a cutting mechanism 10, a feeding mechanism 20, and a blowing mechanism 30. The cutting mechanism 10 is provided with an inlet 111 and an outlet 112. The feeding mechanism 20 is connected to the inlet 111, and the blowing mechanism 30 is connected to the outlet 112. The feeding mechanism 20 is used to feed screws 40 into the cutting mechanism 10 through the inlet 111. The blowing mechanism 30 is used to eject the screws 40 after they enter the blowing mechanism 30 through the outlet 112, allowing them to proceed to the next production stage.

[0044] Furthermore, the cutting mechanism 10 includes a housing 11 and a cutting assembly 12. The aforementioned inlet 111 and outlet 112 are disposed on the housing 11.

[0045] A groove 113 is formed inside the housing 11, and the aforementioned cutting assembly 12 is disposed inside the groove 113 of the housing 11.

[0046] More specifically, the housing 11 includes a base plate 114, a first side wall 115, a second side wall 116, and a cover plate 117. The first side wall 115 and the second side wall 116 are disposed on both sides of the base plate 114, and the cover plate 117 is disposed on the top of the first side wall 115 and the second side wall 116, so that a groove 113 is formed inside the housing 11. The cover plate 117 can be disposed on the groove 113 from above the first side wall 115 and the second side wall 116 to prevent the cutting assembly 12 from shaking, but allows the relevant components of the cutting assembly 12 to slide within the groove 113.

[0047] The feed inlet 111 is formed on the side wall of the housing 11, such as the first side wall 115, and is connected to the feeding mechanism 20. The discharge outlet 112 is formed on the bottom plate 114 and is connected to the blowing mechanism 30. In other words, the feeding mechanism 20 can feed the screw 40 from the side of the housing 11 onto the cutting assembly 12 inside the housing 11. The cutting assembly 12 moves the screw 40 from the feed inlet 111 to the discharge outlet 112, and causes the screw 40 to fall into the blowing mechanism 30 from the discharge outlet 112 by its own weight.

[0048] Please refer to Figures 4 to 9 The cutting assembly 12 also includes a power source 121, a first slider 122, a second slider 123, a blocking part 124, a first spacing adjustment mechanism 125, and a second spacing adjustment mechanism 126. The power source 121 is fixed relative to the housing 11, preferably fixed to the end of the slide groove 113. The first slider 122 is connected to the power source 121 and is slidably disposed within the slide groove 113 under the drive of the power source 121. The second slider 123 is connected to the first slider 122, and a screw storage opening 127 for storing screws 40 is formed between the first slider 122 and the second slider 123. The second slider 123 can move along with the first slider 122 when not obstructed. The blocking part 124 is disposed within the housing 11. After the second slider 123 slides a set distance, the blocking part 124 prevents the second slider 123 from continuing to move, while allowing the first slider 122 to continue moving.

[0049] The first spacing adjustment mechanism 125 is disposed between the first slider 122 and the second slider 123 to adjust the width of the nail storage opening 127 at the feed inlet 111. The second spacing adjustment mechanism 126 is disposed between the second slider 123 and the blocking part 124 to adjust the distance that the second slider 123 can move with the first slider 122.

[0050] In this embodiment, driven by the power source 121, the cutting assembly 12 forms a first state, a second state, and a third state. In the initial stage of the first state, the position of the screw storage port 127 corresponds to the position of the feed port 111. The feeding mechanism 20 feeds the screw 40 from the feed port 111 into the screw storage port 127. The flange on the top of the screw 40 can be placed on the first slider 122 and the second slider 123. The power source 121 starts to drive the first slider 122 to move, and then the first slider 122 drives the second slider 123 to move together. At this time, the movements of the first slider 122 and the second slider 123 are consistent, the width of the screw storage port 127 does not change, and the distance between the second slider 123 and the blocking part 124 gradually decreases. As the movement continues, the second slider 123 contacts the blocking part 124. When the second slider 123 is blocked by the blocking part 124, it enters the second state. In the second state, the second slider 123 stops moving because the blocking part 124 blocks the second slider 123, but the first slider 122 continues to move. At this time, the width of the nail storage port 127 gradually increases. When the nail storage port 127 moves to the discharge port 112, it enters the third state. In the third state, the position of the nail storage port 127 corresponds to the discharge port 112. At the same time, the width of the nail storage port 127 has increased to be greater than the width of the top flange of the screw 40. At this time, the nail storage port 127 can no longer support the screw 40. The screw 40 can fall into the discharge port 112 by gravity and then enter the blowing mechanism 30.

[0051] When changing the type of screw 40, the first pitch adjustment mechanism 125 can be used to adjust the position of the second slider 123 on the first slider 122 in the initial stage of the first state, thereby adjusting the width of the screw storage port 127 at the feed port 111. That is, through the first pitch adjustment mechanism 125, the width of the screw storage port 127 is adapted to the diameter of the screw 40 at the initial stage of the first state by the cutting assembly 12. The second pitch adjustment mechanism 126 adjusts the travel distance of the second slider 123 relative to the blocking part 124, that is, adjusts the termination position of the second slider 123. As the first slider 122 continues to move, when the width of the screw storage port 127 is greater than the width of the flange at the top of the screw 40, the screw 40 will fall from the discharge port 112. That is, by adjusting the termination position of the second slider 123, the width of the screw storage port 127 at the end of the third state can be adjusted to adapt to the width of the flange at the top of the screw 40.

[0052] Please continue to refer to Figures 5 to 9A first supporting portion 1221, a first connecting portion 1222, and a first force-applying portion 1223 are formed on the first slider 122. The first supporting portion 1221 is connected to the first force-applying portion 1223 through the first connecting portion 1222. That is, the first connecting portion 1222 is disposed between the first supporting portion 1221 and the first force-applying portion 1223. The second slider 123 includes a second supporting portion 1231 and a second connecting portion 1232, and the second supporting portion 1231 is connected to the second connecting portion 1232. The aforementioned nail storage slot 127 is formed between the first supporting portion 1221 and the second supporting portion 1231.

[0053] A first recessed receiving groove 1224 is formed in the first connecting portion 1222, and the second connecting portion 1232 is disposed in the first receiving groove 1224 so that the second slider 123 rests on the first slider 122. The length of the first receiving groove 1224 along the length direction of the slide groove 113 is greater than the length of the second connecting portion 1232 along the same direction, so that the second slider 123 can be movably disposed on the first slider 122 relative to the first slider 122.

[0054] In other words, the second slider 123 is supported on the first slider 122 by its own weight. When the second slider 123 is not blocked by the blocking part 124, the first slider 122 will move together with the second slider 123 by the friction generated by the weight of the second slider 123 during the movement.

[0055] The first spacing adjustment mechanism 125 can be an adjusting bolt, which passes through the second connecting portion 1232 from the side away from the discharge port 112 and abuts against the end face of the first receiving groove 1224 facing the discharge port 112. By adjusting the length of the adjusting bolt extending out of the second connecting portion 1232, the width of the nail storage port 127 at the feed port 111 can be adjusted.

[0056] The power source 121 is connected to the first force-applying part 1223 of the first slider 122 to drive the first slider 122 to move. A first elastic member 1225 is also provided between the first force-applying part 1223 and the second connecting part 1232. The first elastic member 1225 can ensure the smooth movement of the first slider 122 and the second slider 123, and can also make the first gap adjustment structure abut against the end face of the first receiving groove 1224 when the cutting assembly 12 is in the first state.

[0057] Furthermore, the aforementioned blocking portion 124 can be formed on the housing 11, specifically as a blocking groove recessed in the second sidewall 116. At least a portion of the second connecting portion 1232 extends into the blocking groove, so that when the second connecting portion 1232 moves to the end of the blocking groove, the blocking groove blocks the movement of the second slider 123. It can be understood that along the length direction of the slide groove 113, the length of the blocking groove is greater than the thickness of the second connecting portion 1232, so that the second connecting portion 1232 can have a certain range of motion within the blocking groove, and when it moves to the end of the blocking groove, the sidewall of the blocking groove prevents the second slider 123 from moving further.

[0058] The second spacing adjustment mechanism 126 can also be an adjusting bolt. The adjusting bolt of the second spacing adjustment mechanism 126 passes through the second connecting part 1232 from the side away from the discharge port 112 and protrudes towards the end of the blocking groove near the discharge port 112. By adjusting the length of the adjusting bolt of the second spacing adjustment mechanism 126 extending out of the second connecting part 1232, the distance that the second slider 123 slides in the blocking groove can be adjusted. When the adjusting bolt of the second spacing adjustment mechanism 126 abuts against the blocking groove, the second slider 123 stops moving.

[0059] Furthermore, the cutting mechanism 10 also includes a third spacing adjustment mechanism 128, which is disposed between the first slider 122 and the second slider 123 to adjust the spacing between the first slider 122 and the second slider 123 when the nail storage port 127 is at the discharge port 112. Then, together with the second spacing adjustment mechanism 126, the width of the nail storage port 127 is adjusted when the nail storage port 127 is at the discharge port 112.

[0060] At this point, in the third state, as the first slider 122 continues to move, the first force-applying part 1223 abuts against the second connecting part 1232, and the movement of the first slider 122 is stopped by the second slider 123, and the width of the nail-holding opening 127 is at its maximum.

[0061] Understandably, the third spacing adjustment mechanism 128 can also be an adjustment bolt. The adjustment bolt of the third spacing adjustment mechanism 128 passes through the first force application part 1223 from the side of the first force application part 1223 away from the discharge port 112 and protrudes in the direction of the second connection part 1232.

[0062] By changing the length of the adjusting bolt, the distance between the second connecting part 1232 and the first force-applying part 1223 can be adjusted, thereby changing the distance that the first slider 122 can continue to move after the blocking part 124 blocks the second slider 123.

[0063] By setting the second spacing adjustment mechanism 126 and the third spacing adjustment mechanism 128, the positions of the first bearing part 1221 and the second bearing part 1231 can be adjusted when the nail storage port 127 is located at the discharge port 112, so that the middle part of the nail storage port 127 corresponds to the axis of the discharge port 112, so that the screw 40 can fall smoothly into the discharge port 112.

[0064] Furthermore, the first slider 122 also includes a second receiving groove 1291, a blocking block 1292, and a fixing bolt 1293. The blocking block 1292 is disposed within the second receiving groove 1291. When the cutting assembly 12 is in the initial position of the first state, the position of the blocking block 1292 corresponds to the position of the feed inlet 111. A strip-shaped groove 1294 perpendicular to the length direction of the slide 113 is formed on the blocking block 1292, and a connecting hole 1295 is formed within the second receiving groove 1291. The fixing bolt 1293 passes through the strip-shaped groove 1294 and extends into the connecting hole 1295 to fix the blocking block 1292 within the second receiving groove 1291. Since the blocking block 1292 is provided with the strip-shaped groove 1294, the length of the blocking block 1292 extending into the nail storage port 127 can be adjusted by different fixing positions of the fixing bolt 1293 and the strip-shaped groove 1294.

[0065] Because screws 40 of different specifications have different flange diameters, the depth to which they enter the screw storage port 127 after entering through the feed port 111 will also be different, meaning the depth to which the axis of the screw 40 extends into the screw storage port 127 will vary. When the screw storage port 127 reaches the discharge port 112, the axis of the screw 40 may deviate from the axis of the discharge port 112.

[0066] This application allows for adaptation to flanges with different specifications of screws 40 by adjusting the length of the blocking block 1292 extending into the screw storage port 127. When the flange diameter is large, the length of the blocking block 1292 extending into the screw storage port 127 can be shortened, while when the flange diameter is small, the length of the blocking block 1292 extending into the screw storage port 127 can be increased. Through the above adjustments, when the screw storage port 127 moves to the discharge port 112, the axis of each specification of screw 40 can correspond to the axis of the discharge port 112.

[0067] Please refer to Figures 10 to 16 The cutting device also includes a cover plate adjustment mechanism 50, which is disposed on the housing 11 and connected to the cover plate 117 to adjust the height of the cover plate 117 covering the housing 11.

[0068] For screws 40 of different specifications, the flange height will vary when the flange of the screw 40 is placed on the screw storage port 127. When the flange height is too high, the cover plate 117 will collide with the flange, preventing the screw 40 from entering the cutting device. When the flange height is too low, the distance between the cover plate 117 and the top of the flange is too large, which can easily cause the screw 40 to wobble. By setting the cover plate adjustment mechanism 50, the height of the cover plate 117 on the housing 11 can be adjusted to adjust the distance between the cover plate 117 and the top of the flange of the screw 40 after the screw 40 enters the screw storage port 127.

[0069] Furthermore, the cover plate adjustment mechanism 50 includes a fixing block 51, a connecting column 52, a second elastic element 53, and an adjusting column 54. The fixing block 51 is fixed to the housing 11, preferably to the side wall of the housing 11. A connecting channel 511 is formed within the fixing block 51. One end of the connecting column 52 is connected to the cover plate 117, and the other end is movably disposed within the connecting channel 511 along the height direction of the housing 11. The second elastic element 53 is disposed between the connecting column 52 and the fixing block 51 to apply an upward or downward force to the connecting column 52, thereby causing the connecting column 52 to move upward or downward. The adjusting column 54 is disposed between the cover plate 117 and the fixing block 51. The adjusting column 54 adjusts the distance between the cover plate 117 and the fixing block 51 and counteracts the force applied to the connecting column 52 by the second elastic element 53.

[0070] When adjusting the height of the cover plate 117, the distance between the cover plate 117 and the fixing block 51 can be adjusted by adjusting the adjusting column 54. Through the connection column 52 and the second elastic element 53, on the one hand, the adjusting column 54 can overcome the force exerted by the second elastic element 53 on the connecting column 52, ensuring stable force so that the cover plate 117 can be relatively stably fixed to the housing 11; on the other hand, during adjustment, as long as the adjusting column 54 is released, the second elastic element 53 can automatically drive the cover plate 117 to reset via the connecting column 52, facilitating adjustment.

[0071] Furthermore, the connecting channel 511 extends vertically through the fixing block 51, one end of the connecting post 52 is connected to the cover plate 117, and the other end extends out of the fixing block 51 through the connecting channel 511. A support surface 521 is provided at the end of the connecting post 52 away from the cover plate 117, and a second elastic member 53 is formed between the support surface 521 and the lower surface of the fixing block 51.

[0072] The adjusting column 54 can be an adjusting bolt. One end of the adjusting column 54 is connected to the cover plate 117, and the other end is connected to the fixing block 51.

[0073] In this embodiment, the second elastic element 53 is a compression spring, which applies a downward force to the connecting column 52, causing the connecting column 52 to tend to move the cover plate 117 downward, that is, towards the direction of the fixing block 51. The end of the adjusting column 54 away from the cover plate 117 abuts against the fixing block 51 to counteract the force of the second elastic element 53.

[0074] Furthermore, a first positioning hole 512 is provided on the fixing block 51. When the cover plate 117 is placed on the housing 11, the adjusting column 54 can extend into the first positioning hole 512 to ensure the stability of the cover plate 117.

[0075] The connecting post 52 is rotatably mounted within the fixing block 51. A second positioning hole 513 is also provided on the fixing block 51. The positions of the second positioning hole 513 and the first positioning hole 512 are symmetrical about the axis of rotation of the connecting post 52. That is, the cover plate 117 can be rotated 180°, and then the adjusting post 54 can be inserted into the second positioning hole 513. The second positioning hole 513 allows the cover plate 117 to be moved above the housing 11, facilitating maintenance of the cutting mechanism 10 inside the housing 11.

[0076] Furthermore, the cover plate 117 can be divided into a first cover plate 1171 and a second cover plate 1172. The first cover plate 1171 is fixed to the housing 11, while the second cover plate 1172 is connected to the connecting post 52 and the adjusting post 54. The second cover plate 1172 covers at least the feed inlet 111 and the discharge outlet 112. That is, the cover plate 117 is divided into at least two parts, with only one part of the cover plate 117 connected to the adjusting post 54. This allows for maintenance of the cutting assembly 12 by simply moving the second cover plate 1172, and also reduces dust entering the chute 113.

[0077] Furthermore, the second cover plate 1172 is also located above the second receiving groove 1291 and the blocking block 1292, which facilitates the adjustment of the length of the blocking block 1292 extending into the nail storage port 127.

[0078] like Figures 14 to 16 As shown, in the working state, the second cover plate 1172 can be placed over the slide groove 113 (e.g., Figure 14 When it is necessary to inspect the cutting assembly 12 or adjust the blocking block 1292, the distance between the second cover plate 1172 and the fixed block 51 can be increased by adjusting the column 54 to lift the second cover plate 1172 (e.g., Figure 15 After lifting the second cover plate 1172, the connecting post 52 can be rotated 180°, so that the second cover plate 1172 is rotated to the other side of the connecting post 52 relative to the slide groove 113, and the adjusting post 54 is inserted into the second positioning hole 513 (e.g. Figure 16At this point, the second cover plate 1172 can be stably fixed at a position above the slide 113, and then the cutting assembly 12 is processed.

[0079] In summary, in this embodiment, by setting multiple spacing adjustment mechanisms on the cutting assembly 12, the width of the nail storage port 127 at the feed port 111 and the width of the nail storage port 127 at the discharge port 112 can be adjusted to adapt to the diameter of the screw shank of each size and the diameter of the flange along the length of the slide groove 113. This avoids the need to replace parts and reduces costs.

[0080] Furthermore, the second receiving groove 1291, the blocking block 1292 and the fixing bolt 1293 can be used to adapt to the diameter of the flange of different types of screws 40 in the width direction of the slide groove 113.

[0081] Furthermore, the cover plate adjustment mechanism 50 allows for adaptation to the flange height of various screw types 40.
