Description

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

[0002] A knife with a handle consists of two parts: a blade and a handle. The handle is designed as two symmetrical structures, which are firmly connected to the blade through paired rivets. Currently, the assembly of knives with handles is mostly done manually, with a low degree of automation, which not only affects production efficiency but also increases the risk of human error. In addition, during the assembly process, when the male nail is embedded in the female nail, the female nail will be expanded. The expansion of the female nail in this process will exert significant radial pressure on the handle, especially when the handle material is relatively brittle and has poor ductility (such as a wooden handle), which may cause cracks in the handle, thereby affecting the overall quality and durability of the product.

When the steam heating box works, the hot steam inside the steam heating box heats the tool handle to 40°C-50°C. After being heated by the steam, the tool handle temporarily becomes softer and more ductile. In this way, when radial pressure is applied to the tool handle when the mother nail expands, the risk of cracks is reduced and the product quality is improved.

[0016] 3. After manually placing the male nail in the mounting hole of the upper tool handle, the rotating rod and the elastic strip are controlled to move downward close to the male nail.

[0021] 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.

[0022] In order to limit the movement of the blade when the electric turntable 2 drives the fixed fixture 3 to rotate, two limit blocks are provided on each fixed fixture 3.

[0023] In order to facilitate the wedge plate 6 to force the mounting plate 5 to move upward, the junction between the mounting plate 5 and the wedge plate 6 is set to be arc-shaped.

[0024] The loading and unloading mechanism comprises 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 fixedly connected 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 driving part; 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 feeding unit 7, the lower tool handle feeding unit 8, the blade feeding unit 9, the upper tool handle feeding unit 10 and the hydraulic press 11 are respectively connected with a visual detector.

[0025] It also includes a camera 1 13 and a camera 2 14 ; the camera 1 13 is fixedly connected to the lifting clamp of the unloading unit 12 ; and the camera 2 14 is fixedly connected to the mounting frame of the unloading unit 12 .

[0026] When working, 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 through 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 front of the staff, the hydraulic press 11 and the unloading unit 12 in sequence; when the fixed fixture 3 rotates to the working area of ​​the mother nail loading unit 7, the mother nail loading unit 7 works to place the three mother nails synchronously in the corresponding placement slot 2 302, and then continues to control the fixed fixture 3 When the fixed fixture 3 is rotated, the lower part of the female nail is restricted by the placement groove 301, and no deflection or displacement occurs during movement; when the fixed fixture 3 is rotated into the working area of ​​the lower tool handle loading unit 8, the lower tool handle loading unit 8 works to place the lower tool handle in the placement groove 301, and the female nail is inserted into the mounting hole on the lower tool handle; when the fixed 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 tool handle; when the fixed fixture 3 is rotated into the working area of ​​the upper tool handle loading unit 10, the upper tool handle loading unit 10 works to place the upper tool handle on the blade; When the fixed fixture 3 is rotated to the front of the staff, the staff will manually check and correct the tool handle and the blade to ensure that the relative position of the blade and the tool handle is correct, thereby ensuring the normal assembly of the tool handle and the blade, and ensuring 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 to 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 presses down the male nail 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 unloading unit 12 in advance, and when the fixed fixture 3 is rotated into the working area of ​​the unloading unit 12, the unloading unit 12 removes the assembled tool and then places 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.

[0027] The mother nail feeding unit 7 is composed of a feeding tube and a pneumatic or hydraulic driving component. When in use, the feeding tube is connected to an external vibrating feeder, and the vibrating feeder works to convey the mother nails into the feeding tube one by one, and then the pneumatic or hydraulic driving component is started to place the mother nails in the feeding tube into the placement groove 301; the lower tool handle feeding unit 8, the blade feeding unit 9 and the upper tool handle feeding 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 conveys 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 place the tool handle or blade into the fixed fixture 3.

[0028] 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 the knife handle is heated by the steam, it 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.

[0029] In order to further improve the quality of the tool, a camera 13 and a camera 2 14 are provided on the unloading unit 12. When the unloading 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 unloading unit 12 in advance. When any defect is found, the unloading unit 12 can transfer the defective tool to the defective tool collection box.

[0030] 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 with a visual detector for monitoring whether the fixed fixture 3 is missing male nails, female nails, lower tool handles, blades and upper tool handles. 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 materials.

[0031] Embodiment 2: on the basis of embodiment 1, as 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 feeding unit 10 and the hydraulic press 11; an electric cylinder 22 is fixedly connected to the mounting frame 21; a mounting plate 23 is fixedly connected to the telescopic end of the electric cylinder 22; three rotating rods 24 are rotatably connected to the mounting plate 23; a plurality 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, all the elastic strips 25 on the same rotating rod 24 are in a positive cone shape 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 surface 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 surface of the male nail; the rotating rod 24 is connected to the power unit; the power unit is connected to the mounting plate 23.

[0032] The power unit includes a gear ring 26, an electric push rod 27, a second mounting frame 28 and a rack 29; a gear ring 26 is fixedly connected to each of the three rotating rods 24; an electric push rod 27 is fixedly connected to the second mounting plate 23; a second mounting frame 28 is fixedly connected to the electric push rod 27; three racks 29 are fixedly connected to the second mounting frame 28; the three racks 29 are respectively meshed with the corresponding gear rings 26.

[0033] 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 the spring telescopic rods 31 are fixedly connected to the second mounting plate 23.

[0034] In order to prevent the upper knife 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.

[0035] 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 crookedly; 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 crookedness 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 reciprocates to drive the gear ring 26 and the rotating rod 2 4 and the elastic strip 25 reciprocate, so that the inclined elastic strip 25 gradually moves downward during the reciprocating rotation. Since the diameter of the annular 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 annular 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 move the male nail, so that the male nail moves back and forth and finally embeds 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 and embeds it into the female nail, thus preventing the male nail from shaking and deflecting during the process of following 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 to perform the riveting operation.

[0036] When the male nail is deflected to a large extent, the elastic strip 25 moves down and contacts the deflected male nail, which will force the male nail to tilt further outward; therefore, a limiting cylinder 32 is provided on the outer side of the elastic strip 25, and the spring telescopic rod 31 and the limiting cylinder 32 move downward with the mounting plate 23. When the limiting cylinder 32 moves down to contact 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, so that the deflected elastic strip 25 places the male nail on its inner side, thereby making the male nail embedded in the female nail, ensuring the normal operation of the subsequent pressing process.
