Description

Technical Field

[0001] The present invention relates to a hardware tool, and particularly to a full-automatic bit rubber sleeve machine. Background Art

[0002] In hardware tools, bits are often used to lock screws. In order to improve the anti-torsion and anti-impact capabilities of the bits, a diameter shrinkage section needs to be formed on the bit during production. A rubber sleeve needs to be tightly sleeved outside the shrinkage section. Currently, the rubber sleeve of the screwdriver bit is operated by manual rubber sleeving. The rubber sleeve is cut to a fixed length by a cutting device, and then the worker manually sleevs the rubber sleeve outside the diameter shrinkage section of the bit. Then, the bits with the rubber sleeves are put into an oven in batches to heat the rubber sleeve to shrink and tightly wrap around the outside of the diameter shrinkage section of the screwdriver bit. This manual rubber sleeving production process has low production efficiency, consumes labor, and the rubber sleeve is prone to failure or falling off during use due to improper socketing, and is also prone to damage during the rubber sleeving process, which is not conducive to ensuring the quality of the bit.

[0028] Embodiment: A fully automatic bit sleeve gluing machine, comprising a bit conveying mechanism 1, a bit positioning device 2, a sleeve feeding mechanism 3, a sleeve pressing mechanism 5, a bit and sleeve heat shrinking mechanism 6 and a control system. The bit positioning device 2 can fixedly position the bit 7 and position the bit 7 in a vertical state. The bit positioning device 2 is positioned on the bit conveying mechanism 1, and the bit conveying mechanism 1 can convey the bit positioning device 2 forward. The sleeve feeding mechanism 3, the sleeve pressing mechanism 5 and the bit and sleeve heat shrinking mechanism 6 are respectively arranged on one side of the bit conveying mechanism 1 at intervals along the bit conveying direction. The sleeve feeding mechanism 3 can sleave a fixed-length sleeve 8 on the outer side of the upper tip of each bit on the bit positioning device 2. The sleeve pressing mechanism 5 includes a sleeve positioning plate 50 and a sleeve pressing driving device 51. The sleeve positioning plate 50 can move up and down and is arranged directly above the bit conveying mechanism 1. The sleeve positioning plate 50 is provided with a through hole 52 with a diameter between the inner diameter of the sleeve and the outer diameter of the upper tip of the bit. The through hole 52 is arranged in one-to-one correspondence with the bit positioned on the bit positioning device 2. The sleeve pressing driving device 51 drives the sleeve positioning plate 50 to move up and down a set distance. The bit and sleeve heat shrinking mechanism 6 can generate heat to cause the passing sleeve to be heated and deformed and shrink on the inner surface of the bit annular groove. The control system controls the start and stop actions of the bit conveying mechanism 1, the sleeve feeding mechanism 3, the sleeve pressing driving device 51 and the sleeve heat shrinking mechanism.

[0029] The working process of the equipment is as follows: Place the bits 7 on the bit positioning device 2 for alignment and positioning, ensure that the bits extend in a vertical state with the pointed ends facing upward, place the bit positioning device 2 equipped with the bits 7 on the bit conveying mechanism 1 and convey it forward. When the bit conveying mechanism 1 reaches the gluing position, the sleeve feeding mechanism 3 sleaves the fixed-length sleeves 8 one by one on the outer sides of the tips of the bits 7 on the bit positioning device 2. Then the bit conveying mechanism 1 continues to convey the bit positioning device 2 forward. When the bit positioning device 2 reaches directly below the sleeve pressing mechanism 5, the sleeve positioning plate 50 of the sleeve pressing mechanism 5 descends, and the pointed end of the bit 7 is correspondingly inserted into the through hole 52 of the sleeve positioning plate 50, and the sleeve 8 is pushed down and finally enters the diameter-shrinking part of the bit, realizing the sleeve being pressed in place. The sleeve pressing mechanism 5 preferably further includes a sleeve pressing support 3053 fixed above the bit conveying mechanism 1, a guide sleeve 54 fixed on the sleeve pressing support 30, and a guide post 55 fixed on the sleeve positioning plate 50 to ensure that the sleeve positioning plate 50 descends in the vertical direction. At the same time, ensure that the through hole 52 on the sleeve positioning plate 50 is directly opposite to the bit one by one. After the sleeve is installed in place, the bit positioning device 2 continues to be conveyed forward and reaches the bit and sleeve heat shrinking mechanism 6. The bit 7 and the bit and sleeve heat shrinking mechanism 6 generate heat to bake the passing sleeve. The sleeve 8 is heated and deformed and shrinks on the inner surface of the bit annular groove, and is integrated with the bit 7, thus completing the automatic bit gluing. The finished product can be taken off the bit positioning device 2. The whole process has a high degree of automation, avoids manual gluing, improves the gluing efficiency and quality, reduces labor, and lowers the production cost.

[0030] The bit and sleeve heat-shrinking mechanism 6 is a shaping oven fixedly arranged at the conveying end of the bit conveying mechanism 1, and the shaping oven covers directly above the conveying end of the bit conveying mechanism 1. By heating the shaping oven, the rubber sleeve is baked, so that it is heated and deformed and shrinks and fuses on the outside of the diameter shrinking section of the bit. In addition, the bit and sleeve heat-shrinking mechanism 6 can also be a hot air blower, and it is also possible to heat and shrink the sleeve by blowing hot air on the sleeve. It can also be heating and baking by an electric heating tube, etc. This is an equivalent replacement structure that can be easily thought of by those skilled in the art according to this patent and belongs to the protection scope of this patent.

[0031] The sleeve feeding mechanism 3 includes a sleeve bracket 30, an open clamping jaw 31, a clamping jaw bracket 32, a clamping jaw slide 33, a clamping jaw folding drive device, a clamping jaw lifting drive device 34 and a clamping jaw translation drive device 35. The sleeve bracket 30 is fixedly mounted on the frame of the batch head conveying mechanism 1, and the clamping jaw slide 33 can be reciprocated and slidably mounted on the sleeve bracket 30 in a horizontal plane. The sliding direction of the clamping jaw slide 33 is perpendicular to the batch head conveying direction. The clamping jaw bracket 32 ​​can be mounted on the clamping jaw slide 33 in a longitudinal lifting motion. The open clamping jaw 31 is mounted on the clamping jaw On the claw bracket 32, the radial dimension of the open jaw 31 can shrink and expand outward, and the open jaw 31 can be inserted into the fixed-length sleeve located on one side of the batch head conveying mechanism 1. The radial dimension of the open jaw 31 can expand outward to open the sleeve. The jaw closure drive device can drive the open jaw 31 to shrink or expand outward, and the jaw lifting drive device 34 and the jaw translation drive device 35 respectively drive the jaw bracket 32 ​​and the jaw slide 33 to move, and the control system controls the start and stop actions of the jaw closure drive device, the jaw lifting drive device 34 and the jaw translation drive device 35. The initial state of the open jaw 31 is a closed state, and the outer size between the jaws is the smallest. The sleeve cut to a fixed length is placed on one side of the screwdriver bit conveying mechanism 1 for positioning, and then the open jaw 31 moves downward and is inserted into the upper end of the sleeve. When the open jaw 31 is inserted into the inner side of the sleeve, the open jaw 31 opens, and the sleeve is expanded by the radial supporting force, and then the open jaw 31 rises with the sleeve and moves horizontally, so that the sleeve moves to just above the screwdriver bit, and then the open jaw 31 brings the sleeve down and sleeves the sleeve on the outside of the screwdriver bit tip, and the open jaw 31 contracts and then rises to exit the sleeve, thus realizing automatic sleeve placement of the sleeve on the outer side of the screwdriver bit tip without manual sleeve placement. In addition, other mechanisms can also be used to achieve sleeve placement, such as using a negative pressure suction mechanism to adsorb the outer circumferential wall of the sleeve to keep the sleeve in an open state, so as to After it is sleeved on the outside of the tip of the screwdriver head, the negative pressure adsorption is stopped to separate from the sleeve, or a conical pin is inserted into the inside of the sleeve to expand the sleeve and send it to the outside of the tip of the screwdriver head, and then the sleeve is pushed downward by the sleeve on the outside of the conical pin, and the sleeve is sleeved on the outside of the screwdriver head, etc. These are all equivalent replacement structures that can be easily thought of by technical personnel in this field based on this patent and belong to the scope of protection of this patent. The lower end of the opening jaw 31 is preferably formed into a tip with a shrunk size to facilitate the rapid insertion of the opening jaw 31 into a relatively flat sleeve to avoid insertion failure. It is also best to set a jaw lifting and expanding slider 49 and a jaw lifting and expanding drive device 48 on the jaw bracket 32 ​​to realize a small lifting movement to realize the opening jaw 31 to be slightly lowered and inserted into the sleeve, and the opening jaw 31 to be slightly raised and separated from the sleeve after the sleeve is sleeved on the screwdriver head.

[0032] The casing feeding mechanism 3 further includes a casing loading tray 36, a casing driving feed roller 37, a casing pressing roller 38, a casing feeding driving device, a casing length-taking detection device 39, a casing cutting knife, a casing cutting driving device 47, a casing tensioning negative pressure suction nozzle 40 and a casing tensioning driving device 41. The casing loading tray 36 is rotatably installed on one side of the casing support 30. The casing driving feed roller 37 and the casing pressing roller 38 are respectively rotatably installed on the casing support 30. The casing feeding driving device drives the casing driving feed roller 37 to rotate intermittently. The casing strip led out from the casing loading tray 36 can be tightly clamped between the outer circumferential surfaces of the casing driving feed roller 37 and the casing pressing roller 38 and is conveyed upward in the vertical direction. A pair of casing tensioning negative pressure suction nozzles 40 are respectively slidably installed on the casing support 30 in the horizontal direction, and the two opposite side walls of the casing strip above the casing driving feed roller 37 and the casing pressing roller 38 are respectively oppositely and negatively pressure-sucked by the pair of casing tensioning negative pressure suction nozzles 40. The casing tensioning driving device 41 drives the pair of casing tensioning negative pressure suction nozzles 40 to move relative to each other on the horizontal plane. The casing cutting knife is arranged above the casing driving feed roller 37 and the casing pressing roller 38. The casing cutting knife can cut the casing strip located above the casing driving feed roller 37 and the casing pressing roller 38. The casing cutting driving device 47 drives the casing cutting knife to move to cut or avoid the casing strip. The casing length-taking detection device 39 can perform fixed-length detection on the conveying length of the casing strip. The casing length-taking detection device 39 is electrically connected and communicates with the control system. The control system controls the start and stop actions of the casing feeding driving device, the casing cutting driving device 47 and the casing tensioning driving device 41.

[0033] The coiled sleeve strip is fed by the sleeve loading disk 36. The sleeve strip is intermittently fed at a fixed length while being clamped by the sleeve driving roller 37 and the sleeve pressing roller 38. The feeding length is detected and controlled by the sleeve length detecting device 39. The sleeve length detecting device 39 can determine the length of the sleeve according to its sleeve length, or can determine the length of the sleeve by detecting the rotation angle of the driving roller. This is a technical solution that can be easily thought of by those skilled in the art according to this application. After the intermittent feeding of the sleeve strip, the sleeve strip is intermittently fed between the paired sleeve tensioning negative pressure suction nozzles 40. The paired sleeve tensioning negative pressure suction nozzles 40 respectively suck the two opposite outer side walls of the flat sleeve strip to fix and position the sleeve strip. At the same time, the sleeve cutting knife cuts the sleeve at a specified position. Since the cut sleeve is sucked by the sleeve tensioning negative pressure suction nozzles 40, it will not fall off, thus realizing fixed-length cutting. Then, the paired sleeve tensioning negative pressure suction nozzles 40 move in the reverse direction to open the sleeve, facilitating the smooth insertion of the opening jaw 31 into the sleeve. This mechanism realizes the direct feeding of the coiled sleeve strip, automatically cuts at a fixed length and facilitates the insertion of the opening jaw 31, without the need to cut and position the sleeve strip in advance, improving the degree of automation and production efficiency. Of course, it is also possible to cut the sleeve strip at a fixed length in other processes first, position the cut fixed-length sleeve on the fixture, and the opening jaw 31 takes the material on the fixture, which also belongs to the protection scope of this application.

[0034] A pair of strip shaping and pressing rollers 42 are rotatably provided on the sleeve bracket 30. Spiral patterns are formed on the circumferential outer surface of the pair of strip shaping and pressing rollers 42. The strip shaping and pressing rollers 42 are located between the sleeve loading disk 36 and the sleeve driving roller 37. The sleeve strip can be pressed when passing through the pair of strip shaping and pressing rollers 42, causing the upper and lower side surfaces to be misaligned to form a pre-opening.

[0035] During the conveying process of the sleeve strip, the two side surfaces of the sleeve strip are pressed by the strip shaping and pressing rollers 42, causing a misalignment between the two side surfaces of the sleeve, and thus tearing the adhered side walls of the sleeve, avoiding the failure of opening after the sleeve strip is cut due to the adhesion between the two side walls, and ensuring the smooth insertion of the opening jaw 31 after the fixed-length cutting of the sleeve strip.

[0036] The sleeve bracket 30 is further provided with a horizontal strip guiding track 43 and a vertical strip guiding track 44. The horizontal strip guiding track 43 extends linearly in the horizontal plane along a direction perpendicular to the bit delivery direction, and the vertical strip guiding track 44 extends in the vertical direction. A pair of horizontally strip guiding rollers 45 and a pair of vertically strip guiding rollers 46 are rotatably provided on the horizontal strip guiding track 43 and the vertical strip guiding track 44 respectively. The sleeve strip is clamped between the pair of horizontally strip guiding rollers 45 and the pair of vertically strip guiding rollers 46 and is conveyed and turned along the extending directions of the horizontal strip guiding track 43 and the vertical strip guiding track 44. The conveyed sleeve strip is vertically conveyed in a turning form after horizontal conveyance, preparing for maintaining a vertical state after the subsequent fixed-length cutting of the sleeve. Moreover, during the forward conveyance of the sleeve strip, it is guided by the horizontal strip guiding track 43, the horizontally strip guiding rollers 45, the vertical strip guiding track 44, and the vertically strip guiding rollers 46, ensuring the linear transmission of the sleeve strip and thus ensuring the accuracy of fixed-length cutting.

[0037] There is also a bit feeding mechanism 9, and the bit feeding mechanism 9 includes a bit feeding support 90, a vibrating feeding tray 91, a connecting track 92, a transition rotating shaft 93, a rotating shaft driving device 94, a bit clamp 95, a clamp base 96, a bit feeding sliding seat 97, a bit feeding driving device 98, a bit lifting driving device 99 and a bit clamp driving device. The bit feeding support 90 is fixedly installed on the frame at the starting section of the bit conveying mechanism 1. The transition rotating shaft 93 is rotatably installed at the lower end of the bit feeding support 90 and can rotate forward and backward. The rotating shaft driving device 94 drives the transition rotating shaft 93 to rotate forward and backward reciprocally. There is a radially extending bit positioning slot 931 on the circumferential outer wall of the transition rotating shaft 93, and the connecting end of the bit can be inserted into the bit positioning slot 931. The vibrating feeding tray 91 is fixedly arranged on one side of the starting section of the bit conveying mechanism 1, and the vibrating feeding tray 91 can arrange and output bits in a set order. The two ends of the connecting track 92 are respectively connected to the discharge port of the vibrating feeding tray 91 and the bit positioning slot 931 on the transition rotating shaft 93. The bit feeding sliding seat 97 is installed at the upper end of the bit feeding support 90 and can linearly reciprocate along a direction perpendicular to the bit conveying direction on a horizontal plane. The bit feeding driving device 98 drives the bit feeding sliding seat 97 to reciprocate. The clamp base 96 is installed on the bit feeding sliding seat 97 and can move up and down longitudinally. The bit lifting driving device 99 drives the clamp base 96 to move up and down. The bit clamp 95 is installed on the clamp base 96, and the bit clamp 95 can clamp or loosen the bit. The bit clamp driving device drives the bit clamp 95 to open and close. The bit clamp 95 can be respectively aligned with the bit positioning slot 931 on the transition rotating shaft 93 and the bit positioning device 2 on the bit conveying mechanism 1. The control system controls the start and stop actions of the shaft driving device, the bit feeding driving device 98, the bit lifting driving device 99 and the bit clamp driving device. After several bits are arranged in an orderly manner in the vibrating feeding tray 91 and output outward, after passing through the connecting track 92, the connecting rod end of the bit is inserted into the bit positioning slot of the transition rotating shaft 93, and then the transition rotating shaft 93 rotates 90 degrees, so that the bit changes from a horizontal state to a vertical state.
