Technical Field
[0001] This utility model relates to the field of robot nail placement technology, specifically a novel six-axis robot nail placement device. Background Technology
[0002] In product manufacturing, injection molding is a common process. During injection molding of plastic parts, some products contain internal threaded features, typically produced through automated molding. However, the thread structure formed in this way often lacks robust performance. To improve the performance of the thread structure, it is often necessary to embed an internal nut into the product.
[0003] Existing traditional pin-setting equipment requires manual handling of products and manual activation of the equipment, which consumes a lot of manpower and time. Traditional processes require manual opening of the injection molding machine door and manual use of air guns to blow into the mold cavity and core. Furthermore, ordinary injection molding machine robots cannot perform pin-setting operations on the front and rear molds simultaneously. Therefore, we propose a new six-axis robotic pin-setting device to solve the above problems. Utility Model Content

[0009] Preferably, the needle-retrieving tube and the pendulum nail post are arranged in a one-to-one correspondence.
[0010] Preferably, the ball guide limit rod and the guide rod are arranged in a one-to-one correspondence.
[0011] Preferably, the adjustment seat has a T-shaped structure.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Compared with conventional nail embedding machine equipment and robotic arms, this application is more stable in nail embedding and picking up and placing, has a higher yield, more uniform nail placement, better torque when the product and nail are integrated, and saves more manpower.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Reference Figure 1-5 This is the first embodiment of the present invention. This embodiment provides a novel six-axis robot nail placement device, including a connecting mounting plate 1. The bottom of the connecting mounting plate 1 is fixedly connected to one end of several connecting columns 2. The other end of the connecting columns 2 is fixedly connected to a support plate 3. Several nail placement and nailing cylinders 4 and inclined copper nail placement and nailing cylinders 5 are fixedly installed on the support plate 3. The driving ends of the nail placement and nailing cylinders 4 and inclined copper nail placement and nailing cylinders 5 are respectively fixedly connected to a needle-retrieving tube 7. The bottom of the needle-retrieving tube 7 is provided with a swing nail column 12, which is located at the top of the lower plate 8.
[0025] Several ball bearing guide limit rods 6 are fixedly installed on the bottom edge of the support plate 3. Guide rods 14 are slidably sleeved inside the ball bearing guide limit rods 6. The end of the guide rod 14 away from the ball bearing guide limit rod 6 is fixedly connected to the lower plate 8. The bottom two sides of the lower plate 8 are fixedly connected to one end of the connecting column 2 9. The other end of the connecting column 2 9 is fixedly connected to the base plate 10. The top two sides of the base plate 10 are respectively hinged to one end of the angle adjustment cylinder 11. The other end of the angle adjustment cylinder 11 is respectively hinged to the opposite side of the adjustment seat 15. The adjustment seat 15 is hinged to one end of the support seat 17. The other end of the support seat 17 is fixedly installed in the adjustment port 16. The adjustment port 16 is provided through the lower plate 8. The opposite side of the adjustment seat 15 is respectively fixedly connected to the nail feeding cylinder 13.
[0026] like Figure 4As shown, a six-axis robot 18 is fixedly mounted on one side of a mounting frame 19, and an electrical control box 20 is fixedly mounted on the other side of the mounting frame 19. The electrical control box 20 is electrically connected to the six-axis robot 18. Various types of copper nails are placed in a vibratory feeder. The copper nails are oriented sequentially by vibration and enter the copper nail flow channel to queue. Various complex copper nails can be automatically corrected and oriented by this vibration method, and then implanted into the fixture in an orderly manner. The nail feeding cylinder 13 pushes and pulls the copper nails into the needle extraction tube 7. The nail-setting cylinder 4 presses down to drive the copper nails into the swivel nail posts 12 on the fixture. The swivel nail posts 12 on the fixture, controlled by a servo forming mechanism, move forward, backward, left, and right to the corresponding swivel nail posts 12 to catch the copper nails. The copper nails are driven into the corresponding swivel nail posts 12 in sequence. When each swivel nail post 12 has nails of various specifications, the fixture stops in a standby position, waiting for the six-axis robot 18 to pick up the nails. After the copper nails are removed, the swivel motion is restarted, repeating the process to achieve fully automatic copper nail placement; the six-axis robot 18 flange... The fixed connection mounting plate 1 realizes two functions: grabbing and placing copper nails. The copper nail grabbing mechanism is used to insert the copper nail into the ejector needle tube 7. Steel balls are installed on both sides of the ejector needle tube 7 to hold the copper nail in place, thus realizing the copper nail grabbing action. After the six-axis robot 18 removes the copper nail, it stops in the standby position, waiting for the mold opening completion signal. After the six-axis robot 18 removes the copper nail, it stops in the standby position, waiting for the injection molding machine's mold opening signal and the injection molding machine's signal to remove the product. The six-axis robot 18 carries the grabbed copper nail. The completed copper nail is taken into the mold and moved to the nail placement position. The nail placement and firing cylinder 4 or the angled copper nail placement and firing cylinder 5 ejects the copper nail from the ejector tube 7 into the mold cavity. Simultaneously, impurities are blown away. After the copper nail is inserted into the cavity and core, the six-axis robot 18 withdraws from the mold area, giving the injection molding machine a mold-locking signal (indicating that the six-axis robot has safely withdrawn and the mold can be locked to produce the next product. When the six-axis robot enters the mold, the mold-locking signal must be turned off to prevent the robot from pressing against the mold while working inside).
[0027] Example 2
[0028] Reference Figure 1-5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the top of the connecting mounting plate 1 is fixedly connected to the drive end of the six-axis robot 18, and the connecting mounting plate 1 is fixedly connected to the flange of the six-axis robot 18, so as to realize the two functions of grabbing copper nails and placing copper nails.
[0029] Specifically, the two sides of the needle-picking tube 7 are equipped with steel balls. The friction of the two balls is used to pick up the copper nail. The steel balls are round and smooth with low friction. Whether picking up or placing copper nails, the resistance is very small, which improves the precision of the parts processing.
[0030] Specifically, the ejector needle tube 7 and the pendulum nail column 12 are set in a one-to-one correspondence, which enables the ejector needle tube 7 to accurately grasp the copper nail.
[0031] Specifically, the ball guide limit rod 6 and the guide rod 14 are set in a one-to-one correspondence to ensure the stability of the connection.
[0032] Specifically, the adjusting seat 15 has a T-shaped structure, and the T-shaped adjusting seat 15 has a support seat 17 hinged in the middle, which facilitates the adjustment of the tilt angle of the nail feeding cylinder 13.
[0033] Example 3
[0034] Reference Figure 1-5 This is the third embodiment of the present invention, which is based on the above two embodiments. When used, as follows: Figure 4 As shown, a six-axis robot 18 is fixedly mounted on one side of a mounting frame 19, and an electrical control box 20 is fixedly mounted on the other side of the mounting frame 19. The electrical control box 20 is electrically connected to the six-axis robot 18. Various types of copper nails are placed in a vibratory feeder. The copper nails are oriented sequentially by vibration and enter the copper nail flow channel to queue. Various complex copper nails can be automatically corrected and oriented by this vibration method, and then implanted into the fixture in an orderly manner. The nail feeding cylinder 13 pushes and pulls the copper nails into the needle extraction tube 7. The nail-setting cylinder 4 presses down to drive the copper nails into the swivel nail posts 12 on the fixture. The swivel nail posts 12 on the fixture, controlled by a servo forming mechanism, move forward, backward, left, and right to the corresponding swivel nail posts 12 to catch the copper nails. The copper nails are driven into the corresponding swivel nail posts 12 in sequence. When each swivel nail post 12 has nails of various specifications, the fixture stops in a standby position, waiting for the six-axis robot 18 to pick up the nails. After the copper nails are removed, the swivel motion is restarted, repeating the process to achieve fully automatic copper nail placement; the six-axis robot 18 flange... The fixed connection mounting plate 1 realizes two functions: grabbing and placing copper nails. The copper nail grabbing mechanism is used to insert the copper nail into the ejector needle tube 7. Steel balls are installed on both sides of the ejector needle tube 7 to hold the copper nail in place, thus realizing the copper nail grabbing action. After the six-axis robot 18 removes the copper nail, it stops in the standby position, waiting for the mold opening completion signal. After the six-axis robot 18 removes the copper nail, it stops in the standby position, waiting for the injection molding machine's mold opening signal and the injection molding machine's signal to remove the product. The six-axis robot 18 carries the grabbed copper nail. The completed copper nail is taken into the mold and moved to the copper nail placement position. The nail placement and nailing cylinder 4 or the inclined copper nail placement and nailing cylinder 5 ejects the copper nail from the ejector tube 7 into the mold cavity. At the same time, impurities are blown out. After the copper nail is driven into the cavity and core, the six-axis robot 18 withdraws from the mold area and sends a mold locking signal to the injection molding machine (indicating that the six-axis robot has safely withdrawn and the mold can be locked to produce the next product. When the six-axis robot enters the mold, the mold locking signal must be turned off to prevent the robot from pressing the mold while working in the mold).
