Description

Technical Field

[0001] The present application relates to the technical field of tool assembly, and in particular to an automatic assembly device for tool with handle. Background Art

[0002] A tool with a handle consists of a blade and a handle. The handle is designed as a symmetrical two-piece structure, firmly connected to the blade by paired rivets.

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example 1: An automatic assembly device for tool with handle, such as Figures 1-9 As shown, it includes a base 1 and a hydraulic press 11; the base 1 is connected to the hydraulic press 11;

[0029] It also includes an electric turntable 2, a fixed fixture 3, a loading and unloading mechanism, a connecting rod 4, a mounting plate 5, a wedge plate 6 and a steam heating box 15; the electric turntable 2 is connected to the base 1; a number of fixed fixtures 3 are fixedly connected to the electric turntable 2 in a ring at equal intervals; the loading and unloading mechanism is connected to the base 1; each fixed fixture 3 is provided with a placement slot 1 301 and three placement slots 2 302; each fixed fixture 3 is slidably connected to a connecting rod 4; the lower parts of all connecting rods 4 on the same fixed fixture 3 are fixedly connected to a mounting plate 5; a wedge plate 6 is fixed to the base 1; the loading and unloading mechanism is connected to the steam heating box 15.

[0030] In order to facilitate the placement of the female nail into the second placement groove 302, an arc chamfer is provided on the upper part of the second placement groove 302.

[0031] In order to ensure that the movement of the blade is restricted when the electric turntable 2 drives the fixed fixture 3 to rotate, two limit blocks are provided on each fixed fixture 3.

[0032] In order to facilitate the wedge-shaped plate 6 to force the mounting plate 1 5 to move upward, the junction between the mounting plate 1 5 and the wedge-shaped plate 6 is configured to be arc-shaped.

[0033] The loading and unloading mechanism includes a mother nail loading unit 7, a lower tool handle loading unit 8, a blade loading unit 9, an upper tool handle loading unit 10 and a unloading unit 12; the mother nail loading unit 7, the lower tool handle loading unit 8, the blade loading unit 9, the upper tool handle loading unit 10 and the unloading unit 12 are fixed to the base 1, and the mother nail loading unit 7, the lower tool handle loading unit 8, the blade loading unit 9, the upper tool handle loading unit 10, the hydraulic press 11 and the unloading unit 12 are arranged clockwise around the electric turntable 2; a steam heating box 15 is respectively provided on the electric conveyor belts of the lower tool handle loading unit 8 and the upper tool handle loading unit 10; the mother nail loading unit 7 is composed of a unloading pipe and a pneumatic or hydraulic drive component; the lower tool handle loading unit 8, the blade loading unit 9 and the upper tool handle loading unit 10 are all composed of a screw moving part, a lifting clamping part and an electric conveyor belt; the unloading unit 12 is composed of a screw moving part and a lifting clamping part. The female nail loading unit 7, the lower tool handle loading unit 8, the blade loading unit 9, the upper tool handle loading unit 10 and the hydraulic press 11 are respectively connected to a visual detector.

[0034] It also includes camera 1 13 and camera 2 14 ; camera 1 13 is fixedly connected to the lifting clamp of the blanking unit 12 ; camera 2 14 is fixedly connected to the mounting frame of the blanking unit 12 .

[0035] During work, let the staff sit or stand on the left side of the upper tool handle loading unit 10, and control the electric turntable 2 to drive the fixed fixture 3 to rotate intermittently clockwise based on the view from top to bottom. The empty fixed fixture 3 rotates in sequence through the female nail loading unit 7, the lower tool handle loading unit 8, the blade loading unit 9, the upper tool handle loading unit 10, the front of the staff, the hydraulic press 11 and the unloading unit 12; when the fixed fixture 3 rotates into the working area of the female nail loading unit 7, the female nail loading unit 7 works to place the three female nails synchronously in the corresponding placement slot 2 302, and then continues to control the fixed fixture 3 When the fixing fixture 3 is rotated, the lower part of the female nail is restricted by the placement groove 1 301, and no deflection or displacement occurs during movement; when the fixing fixture 3 is rotated into the working area of the lower knife handle loading unit 8, the lower knife handle loading unit 8 works to place the lower knife handle in the placement groove 1 301, and the female nail is inserted into the mounting hole on the lower knife handle; when the fixing fixture 3 is rotated into the working area of the blade loading unit 9, the blade loading unit 9 works to place the lower blade on the lower knife handle; when the fixing fixture 3 is rotated into the working area of the upper knife handle loading unit 10, the upper knife handle loading unit 10 works to place the upper knife handle on the blade; When the fixed fixture 3 is rotated in front of the staff, the staff will manually check and correct the tool handle and blade to ensure that the relative positions of the blade and the tool handle are correct, thereby ensuring the normal assembly of the tool handle and blade and the quality of the assembled tool. After confirmation, the male nail is placed in the mounting hole of the upper tool handle; when the fixed fixture 3 is rotated into the working area of the hydraulic press 11, the mounting plate 5 will move on the wedge plate 6, and the wedge plate 6 forces the mounting plate 5 and the connecting rod 4 to move upward. After the connecting rod 4 moves upward, the upper side of the connecting rod 4 is flush with the inner bottom side of the placement groove 301, so that the lower side of the female nail is aligned with the tool. The lower side of the handle is flush to ensure that the female nail will not protrude from the handle after assembly. Then, the hydraulic press 11 works to press the male nail down so that the male nail is completely embedded in the female nail, so that the female nail and the male nail are riveted together, so that the blade and the handle are firmly assembled together; a tool collection box is placed on the side of the blanking unit 12 in advance. When the fixed fixture 3 rotates into the working area of the blanking unit 12, the blanking unit 12 works to remove the assembled tool and then place it in the tool collection box for collection; in this way, the automated assembly of the tool is completed, reducing the manual dependence in the assembly process of the tool with handle and improving the production effect.

[0036] The mother nail loading unit 7 is composed of a feeding pipe and a pneumatic or hydraulic driving component. When in use, the feeding pipe is connected to an external vibrating feeder, and the vibrating feeder works to transport the mother nails one by one into the feeding pipe, and then the pneumatic or hydraulic driving component is started to place the mother nails in the feeding pipe into the placement groove 301; the lower tool handle loading unit 8, the blade loading unit 9 and the upper tool handle loading unit 10 are all composed of a screw moving part, a lifting clamping part and an electric conveyor belt. When in use, a manual or decentralized mechanism places the tool handle or blade one by one on the corresponding electric conveyor belt, and the electric conveyor belt transports the tool handle or blade to the bottom of the corresponding lifting clamping part. The lifting clamping part works to clamp the tool handle or blade, and then the screw moving part drives the lifting clamping part to move to the top of the fixed fixture 3, and finally the lifting clamping part works to lower the tool handle or blade into the fixed fixture 3.

[0037] When the male nail is embedded in the female nail, the male nail expands the female nail, and the two are tightly combined to form a mechanical interlock, which firmly fixes the knife handle and the tool together: in this process, the female nail will exert radial pressure on the knife handle when it expands. When the knife handle material is relatively brittle and has poor ductility (such as a wooden knife handle), it may cause cracks in the knife handle, thereby affecting the overall quality of the product; therefore, a steam heating box 15 is respectively provided on the electric conveyor belts of the lower knife handle loading unit 8 and the upper knife handle loading unit 10. When the lower knife handle and the upper knife handle are transported on the electric conveyor belt, they will pass through the steam heating box 15. When the steam heating box 15 is working, the hot steam inside it will heat the knife handle to 40℃-50℃. After being heated by the steam, the knife handle temporarily becomes softer and more ductile. In this way, when the female nail expands and exerts radial pressure on the knife handle, the risk of cracks is reduced and the product quality is improved.

[0038] In order to further improve the quality of the tool, a camera 13 and a camera 2 14 are provided on the blanking unit 12. When the blanking unit 12 transfers the assembled tool clamp to the tool collection box, the camera 13 inspects the upper part of the tool and the camera 2 14 inspects the lower part of the tool to detect whether the tool handle is cracked and whether the male and female nails are protruding. A defective tool collection box is placed on the side of the blanking unit 12 in advance. When any defect is found, the blanking unit 12 can transfer the defective tool into the defective tool collection box.

[0039] In addition, the female nail loading unit 7, the lower tool handle loading unit 8, the blade loading unit 9, the upper tool handle loading unit 10 and the hydraulic press 11 are respectively connected to a visual detector for monitoring whether there is a lack of male nails, female nails, lower tool handles, blades and upper tool handles on the fixed fixture 3. When a shortage of materials is found, the electric turntable 2 is controlled to drive the fixed fixture 3 to rotate counterclockwise back to the previous process for replenishing the materials.

[0040] Example 2: Based on Example 1, Figure 3 、 Figure 7 and Figure 8 As shown, it also includes a mounting frame 21, an electric cylinder 22, a mounting plate 23, a rotating rod 24, an elastic strip 25 and a power unit; a mounting frame 21 is welded on the base 1; the mounting frame 21 is located between the upper tool handle loading unit 10 and the hydraulic press 11; the mounting frame 21 is fixedly connected to the electric cylinder 22; the telescopic end of the electric cylinder 22 is fixedly connected to the mounting plate 23; three rotating rods 24 are rotatably connected to the mounting plate 23; a number of inclined elastic strips 25 are fixedly connected to the lower side of each rotating rod 24, all the elastic strips 25 on the same rotating rod 24 are arranged in a ring shape, and all the elastic strips 25 on the same rotating rod 24 are in the shape of a right cone as a whole. The diameter of the circular track formed by the upper ends of all the elastic strips 25 on the same rotating rod 24 is the same as the diameter of the upper side of the male nail, and the diameter of the circular track formed by the lower ends of all the elastic strips 25 on the same rotating rod 24 is larger than the diameter of the upper side of the male nail; the rotating rod 24 is connected to the power unit; the power unit is connected to the mounting plate 23.

[0041] The power unit includes a gear ring 26, an electric push rod 27, a second mounting frame 28 and a rack 29; each of the three rotating rods 24 is fixed with a gear ring 26; the second mounting plate 23 is fixed with an electric push rod 27; the second mounting frame 28 is fixed with the electric push rod 27; the second mounting frame 28 is fixed with three racks 29; the three racks 29 are respectively engaged with the corresponding gear rings 26.

[0042] It also includes a spring telescopic rod 31 and a limiting cylinder 32; each rotating rod 24 is slidably connected to a limiting cylinder 32; each limiting cylinder 32 is fixedly connected to two spring telescopic rods 31; all spring telescopic rods 31 are fixedly connected to the mounting plate 23.

[0043] In order to prevent the upper handle from being crushed, the lower side of the limiting cylinder 32 is configured to be made of an elastic material, such as silicone rubber.

[0044] When manually placing the male nail in the mounting hole of the upper tool handle, if the operator is negligent for a moment, the male nail may be placed at an angle; in addition, since the male nail is not effectively fixed after placement, it is easy to shake during the rotation of the fixing fixture 3, which further aggravates the deflection of the male nail; once the male nail fails to be vertically embedded in the female nail, the male nail cannot be accurately and completely embedded in the female nail in the subsequent pressing process performed by the hydraulic press 11, which ultimately leads to unqualified products; therefore, after placing the male nail in the mounting hole of the upper tool handle, the electric turntable 2 is controlled to drive the fixing fixture 3 to rotate to the bottom of the mounting plate 23, and then stop. At this time, the male nail is located directly below the corresponding rotating rod 24, and then the electric cylinder 22 is controlled to drive the mounting plate 23, the rotating rod 24 and the elastic strip 25 to move downward. During the movement, the electric push rod 27 is controlled to drive the mounting frame 28 and the rack 29 to move back and forth, and the rack 29 moves back and forth to drive the gear ring 26 and the rotating rod 2 4 and the elastic strip 25 rotate back and forth, so that the inclined elastic strip 25 gradually moves downward during the reciprocating rotation. Since the diameter of the circular track formed by the upper ends of all the elastic strips 25 on the same rotating rod 24 is the same as the diameter of the upper side of the male nail, the diameter of the circular track formed by the lower ends of the elastic strips 25 is larger than the diameter of the upper side of the male nail. When the elastic strip 25 contacts the deflected male nail, the deflected elastic strip 25 will place the male nail inside it, and at the same time, the reciprocating elastic strip 25 will push the male nail, causing the male nail to move back and forth and finally embed into the female nail, ensuring the normal operation of the subsequent pressing process; as the rotating rod 24 continues to move downward, the middle part of the lower side of the rotating rod 24 contacts the male nail, and then the rotating rod 24 pre-presses the male nail into the female nail, thus preventing the male nail from shaking and deflecting during the rotation and movement of the fixing fixture 3; then the electric turntable 2 is controlled to drive the fixing fixture 3 to rotate to the working area of the hydraulic press 11 for riveting.

[0045] When the male nail is deflected to a large extent, the elastic strip 25 moves down and contacts the deflected male nail, forcing the male nail to tilt further outward; therefore, a limiting cylinder 32 is provided on the outside of the elastic strip 25, and the spring telescopic rod 31 and the limiting cylinder 32 follow the movement and decline of the mounting plate 23. When the limiting cylinder 32 moves down and contacts the upper knife handle, it no longer moves downward. When the mounting plate 23, the rotating rod 24 and the elastic strip 25 continue to move downward, the mounting plate 23 will compress the spring telescopic rod 31. In this way, when the elastic strip 25 moves down and contacts the deflected male nail, the elastic strip 25 and the outer side of the deflected male nail are restricted by the limiting cylinder 32 to prevent the male nail from tilting further outward, allowing the deflected elastic strip 25 to place the male nail inside it, thereby allowing the male nail to be embedded in the female nail, ensuring the normal operation of the subsequent pressing process.

[0046] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
