Description

Technical Field

[0001] This invention relates to the field of nail embedding technology, specifically to a fully automatic nail embedding device. Background Technology

[0002] During the production and processing of injection molded products, it is sometimes necessary to install metal inserts such as screws and nuts into the reserved holes of the product to facilitate subsequent assembly. At present, when nailing, the nail embedding machine uses technologies such as vibration feeding, heating preheating and CNC implantation to accurately implant nuts or inserts into plastic or metal workpieces, thereby achieving efficient fastening. It is widely used in 3C electronics, automobile manufacturing, home appliances and other fields.

[0003] However, in the existing technology, when nailing the molded injection products with a nailing machine, it is usually necessary to manually place the injection products one by one into the positioning fixture, manually identify the front and back of the product and adjust the orientation, and manually remove the material after nailing is completed. It requires manual participation in the product loading, flipping, positioning and adjustment, etc., which results in low overall efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a fully automatic nail-burying device, which solves the problem of low work efficiency caused by reliance on manual operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic nail-embedding device, comprising a worktable, a work box on the worktable, longitudinal moving components on both sides of the work box for driving the work box to move longitudinally, a hollow upper end of the work box, a slider slidably mounted on the work box, a transverse moving component inside the work box for driving the slider to move transversely along the work box, a base mounted on the slider, a nail-embedding device at the lower end of the base, a support mounted on the worktable, a material tray on the support for holding products, multiple springs mounted at the bottom of the material tray, each spring having a support column connected to its other end, the support column being fixedly mounted on the support, a winnowing mechanism below the material tray for winnowing the material tray in cooperation with the springs, and a positioning fixture mounted on the worktable with multiple evenly arranged positioning slots for positioning and fixing the injection-molded product.

[0006] The above technical solution involves using a winnowing mechanism to randomly flip the injection-molded products in the tray, then using a picking mechanism to pick up the front-side products from the tray and place them into the positioning slot of the positioning fixture. The nailing device then performs its work, achieving fully automated operation, effectively solving the problems of traditional manual operation and improving work efficiency.

[0007] Preferably, a material picking mechanism is provided on one side of the material tray. The material picking mechanism includes a vision detector and a suction nozzle. The vision detector is used to identify the front and back of the product in the material tray and mark the front of the product. The suction nozzle is used to pick up the product with the front mark and transfer the product to the positioning fixture for placement. The material picking mechanism also includes a robotic arm installed on the side wall of the support. The suction nozzle is located at the end of the robotic arm. The robotic arm drives the suction nozzle to move. The vision detector is fixed to the support by an L-shaped strip and is located above the material tray.

[0008] Preferably, the longitudinal movement assembly includes first screws installed on both sides of the work box, the first screws passing through the work box, the work box having threaded holes at both ends, the first screws being threadedly connected to the work box, each first screw having a pulley installed at its end, the pulleys being driven by a belt, and the longitudinal movement assembly further including a drive motor installed on the worktable, the output end of the drive motor being connected to one of the first screw ends.

[0009] Preferably, the lateral movement assembly includes a second screw installed inside the upper end of the work box, one end of the second screw passing through a slider and inserted into the side wall of the work box, the lower end of the slider having a threaded hole, the slider being threadedly connected to the second screw, and a servo motor being installed at the end of the work box, the output end of the servo motor being connected to the end of the second screw.

[0010] Preferably, the winnowing mechanism includes a turntable disposed above the support and located below the material tray. Multiple control blocks are equidistantly arranged on the circumference of the upper surface edge of the turntable. A guide groove is provided on one side of each control block. A connecting rod is provided at the bottom of the material tray, and a rotatable guide wheel is provided at the bottom end of the connecting rod. The winnowing mechanism also includes a motor mounted on the support, and the output end of the motor is connected to the bottom of the turntable.

[0011] Preferably, when the control block approaches the connecting rod, the guide wheel rolls along the guide groove, and the guide wheel and the guide groove cooperate to drive the connecting rod to move downward and compress the spring. When the guide wheel disengages from the guide groove, the spring is released and causes the material tray to shake.

[0012] Preferably, the opening of the guide groove is V-shaped, and the guide groove is adapted to the guide wheel.

[0013] Preferably, the upper end of the work box has symmetrical square holes, the slider passes through the square holes and is fitted onto the work box, the bottom of the slider is provided with multiple pulleys, and the inside of the work box has grooves that are compatible with the pulleys.

[0014] Preferably, the nailer is provided with multiple nail heads.

[0015] Preferably, the workbench is provided with multiple support blocks, and the end of the first screw is inserted into the support block and can rotate therein.

[0016] Working Principle: During operation, the injection molded product to be embedded is placed into the material tray. The motor is started, and its output drives the turntable to rotate stably. Multiple control blocks on the turntable move synchronously in a circular motion. When one of the control blocks rotates to directly under the guide wheel, the guide wheel smoothly slides into the guide groove under the guidance of the guide groove and rolls along the track, causing the connecting rod and the material tray to move downwards. The spring is compressed and deformed. After the guide wheel leaves the guide groove, the spring releases its elasticity, causing the material tray to bounce back and oscillate, causing the injection molded products in the tray to flip irregularly. This oscillation action is repeated cyclically under the continuous drive of the motor to ensure that the products are fully flipped. Subsequently, the material handling mechanism starts working. The vision detector fixed on the bracket identifies the front and back of the products in the tray and marks the front products. The machine on the side wall of the bracket... The robotic arm drives the suction nozzle at its end to pick up the marked front-facing products from the material tray and precisely transfers them into the positioning slot of the positioning fixture, realizing automatic product picking and loading. After the products are positioned and fixed, the drive motor is started to drive one of the first screws to rotate. Through the transmission cooperation of pulleys and belts, the two first screws rotate synchronously, thereby driving the work box to move smoothly longitudinally. At the same time, the servo motor of the transverse movement component in the work box drives the second screw to rotate. The slider threaded to the second screw drives the base and nailer on it to move laterally. Through the cooperation of longitudinal and transverse movements, the nailer is precisely moved to the nailing position of the product in the positioning slot. Multiple nailing heads on the nailer work synchronously to nail multiple positioned products in the transverse or longitudinal direction.

[0017] This invention provides a fully automatic nail-embedding device. It has the following beneficial effects:

[0018] 1. This invention uses a winnowing mechanism and a material picking mechanism. The winnowing mechanism randomly flips the injection molded products in the tray, and the material picking mechanism picks up the front-side products from the tray and places them into the positioning slot of the positioning fixture. Then the nailing device works, realizing fully automatic operation, effectively solving the problem of traditional manual operation and improving work efficiency.

[0019] 2. The present invention uses longitudinal and transverse moving components to drive the base and nailer to move in multiple directions, thereby realizing the nailing work on the product in the positioning slot.

[0020] 3. The present invention uses a spring that works in conjunction with a winnowing mechanism to shake the tray, thereby causing the products in the tray to flip irregularly. Attached Figure Description

Detailed Implementation

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figures 1-6This invention provides a fully automatic nail-embedding device, including a workbench 1, a work box 2 on the workbench 1, longitudinal moving components 3 on both sides of the work box 2 for driving the work box 2 to move longitudinally, the upper end of the work box 2 is hollow, a slider 4 is slidably installed on the work box 2, a transverse moving component 5 is provided inside the work box 2 for driving the slider 4 to move transversely along the work box 2, a base 6 is installed on the slider 4, a nail-embedding device 7 is provided at the lower end of the base 6, a bracket 8 is installed on the workbench 1, a material tray 9 is provided on the bracket 8 for holding products, a plurality of springs 10 are installed at the bottom of the material tray 9, and a support column 11 is connected to the other end of each spring 10. The support column 11 is fixedly installed on the bracket 8, a winnowing mechanism 12 is provided below the material tray 9, the winnowing mechanism 12 and the springs 10 cooperate to drive the material tray 9 to winnow, a positioning fixture 13 is installed on the workbench 1, the positioning fixture 13 is provided with a plurality of evenly arranged positioning grooves for positioning and fixing injection molded products.

[0030] Specifically, by setting up a workbench 1, a work box 2, a longitudinal moving component 3, a transverse moving component 5, a machine base 6, a nail driver 7, a winnowing mechanism 12, and a positioning fixture 13, the fully automated integrated nail-laying operation is achieved. The longitudinal moving component 3 can drive the machine base 6 and the nail driver 7 to move longitudinally, and the transverse moving component 5 can drive the machine base 6 and the nail driver 7 to move laterally, realizing multi-directional adjustment of the nailing position. The material tray 9, spring 10, and winnowing mechanism 12 work together to drive the material tray 9 to winnow, causing the injection molded products in the material tray 9 to flip irregularly, which is convenient for subsequent material removal. The positioning groove of the positioning fixture 13 can accurately position and fix the injection molded products, avoiding product displacement during nailing, effectively replacing traditional manual operation, greatly improving work efficiency and nailing accuracy, and reducing manual labor intensity.

[0031] Reference Figure 1 and Figure 5 A material picking mechanism 14 is provided on one side of the material tray 9. The material picking mechanism 14 includes a vision detector 1401 and a suction nozzle 1402. The vision detector 1401 is used to identify the front and back of the product in the material tray 9 and mark the front of the product. The suction nozzle 1402 is used to pick up the product marked on the front and transfer the product to the positioning fixture 13 for placement. The material picking mechanism 14 also includes a robotic arm 1403 installed on the side wall of the bracket 8. The suction nozzle 1402 is located at the end of the robotic arm 1403. The robotic arm 1403 drives the suction nozzle 1402 to move. The vision detector 1401 is fixed on the bracket 8 by an L-shaped strip. The vision detector 1401 is located above the material tray 9.

[0032] Specifically, a material handling mechanism 14 is set on one side of the material tray 9. The material handling mechanism 14 includes a vision detector 1401, a suction nozzle 1402, and a robotic arm 1403. The vision detector 1401 can accurately identify the front and back of the products in the material tray 9 and mark the front products to avoid the back products from affecting the nailing quality. The suction nozzle 1402 can stably pick up the front-marked products. The robotic arm 1403 can drive the suction nozzle 1402 to move flexibly and accurately transfer the products into the positioning slot of the positioning fixture 13, realizing automatic material handling and feeding without manual intervention, further improving the automation level of the device, while improving the accuracy and efficiency of material handling and feeding, and ensuring the continuity of subsequent nailing operations.

[0033] Reference Figure 1 and Figure 2 The longitudinal moving component 3 includes a first screw 301 installed on both sides of the working box 2. The first screw 301 passes through the working box 2. The working box 2 has threaded holes at both ends. The first screw 301 is threadedly connected to the working box 2. Each first screw 301 has a pulley 302 installed at its end. The pulleys 302 are driven by a belt. The longitudinal moving component 3 also includes a drive motor 303 installed on the worktable 1. The output end of the drive motor 303 is connected to the end of one of the first screws 301.

[0034] Specifically, the drive motor 303 can drive one of the first screws 301 to rotate. Through the transmission cooperation of the pulley 302 and the belt, the two first screws 301 can rotate synchronously. Since the first screw 301 is threadedly connected to the working box 2, it can drive the working box 2 to move smoothly in the longitudinal direction. The transmission is smooth and the adjustment accuracy is high, which ensures the accuracy of the longitudinal nailing position of the nailer 7. At the same time, the structure is simple, the failure rate is low, and it is easy to maintain, which provides a guarantee for the stable operation of the device.

[0035] Reference Figure 2 and Figure 3 The lateral movement component 5 includes a second screw 501 installed inside the upper end of the work box 2. One end of the second screw 501 passes through the slider 4 and is inserted into the side wall of the work box 2. The lower end of the slider 4 is provided with a threaded hole. The slider 4 is threadedly connected to the second screw 501. A servo motor 502 is installed at the end of the work box 2. The output end of the servo motor 502 is connected to the end of the second screw 501.

[0036] Specifically, the second screw 501 is threadedly connected to the slider 4, which can drive the slider 4, the base 6 and the nailer 7 to move smoothly laterally along the work box 2. This allows for precise control of the slider 4's movement distance, thereby precisely adjusting the lateral nailing position of the nailer 7 to meet the nailing needs of products with different spacing.

[0037] Reference Figure 4 and Figure 6The winnowing mechanism 12 includes a turntable 1201 mounted above the support 8, located below the material tray 9. Multiple control blocks 1202 are equidistantly arranged around the circumference of the upper surface edge of the turntable 1201. A guide groove is provided on one side of each control block 1202. A connecting rod 1203 is located at the bottom of the material tray 9, and a rotatable guide wheel 1204 is located at the bottom end of the connecting rod 1203. The winnowing mechanism 12 also includes a motor 1205 mounted on the support 8, with its output end connected to the bottom of the turntable 1201. When the control block 1202 approaches the connecting rod 1203, the guide wheel 1204 rolls along the guide groove. The guide wheel 1204 and the guide groove cooperate to move the connecting rod 1203 downwards and compress the spring 10. When the guide wheel 1204 disengages from the guide groove, the spring 10 releases, causing the material tray 9 to winnow. The opening of the guide groove is V-shaped, and the guide groove and guide wheel 1204 are mutually compatible.

[0038] Specifically, the motor 1205 drives the turntable 1201 to rotate stably. The control block 1202 on the turntable 1201 rotates with the turntable 1201 and cooperates with the guide wheel 1204 on the bottom connecting rod 1203 of the material tray 9. This allows the connecting rod 1203 to move up and down, which in turn cooperates with the spring 10 to make the material tray 9 shake. This ensures that the injection molded products in the material tray 9 are fully flipped, avoids product accumulation that would prevent the identification of the front and back sides, and ensures the material picking efficiency of the picking mechanism 14. By setting the opening of the guide groove to be V-shaped and the guide groove and the guide wheel 1204 to be compatible, the guide wheel 1204 can be guided to enter the guide groove smoothly, avoiding jamming or collision between the guide wheel 1204 and the control block 1202. This ensures the stability of the cooperation between the guide wheel 1204 and the guide groove, thereby ensuring the smoothness of the up and down movement of the connecting rod 1203, making the shaking action of the material tray 9 smoother and improving the product flipping effect.

[0039] Reference Figure 1 and Figure 2 The upper end of the work box 2 is symmetrically provided with square holes. The slider 4 passes through the square holes and is fitted onto the work box 2. The bottom of the slider 4 is provided with multiple pulleys 15. The inside of the work box 2 is provided with sliding grooves that are compatible with the pulleys 15. The nailer 7 is provided with multiple nail heads. The worktable 1 is provided with multiple support blocks 16. The end of the first screw 301 is inserted into the support block 16 and can rotate therein.

[0040] Specifically, by setting a pulley 15 at the bottom of the slider 4 and opening a groove inside the work box 2 to match the pulley 15, the cooperation between the pulley 15 and the groove can significantly reduce the friction between the slider 4 and the work box 2 when the slider 4 moves laterally, making the slider 4 move more smoothly and stably, avoiding jamming when the slider 4 moves, ensuring the stability and accuracy of the nailer 7, while reducing component wear and extending the overall service life of the device; by setting multiple nail heads on the nailer 7, multiple products can be nailed in the horizontal or vertical direction in a single nailing process, which can fully adapt to the multiple evenly arranged positioning slots on the positioning fixture 13, realize the simultaneous nailing of multiple products, and improve the efficiency of nailing operation.
