Abstract
Description
Technical Field
[0001] This utility model belongs to the field of suction nozzle technology, and in particular relates to a double guide post suction nozzle. Background Technology
[0002] In industrial equipment such as automated production lines, vacuum equipment, and injection molding machines, nozzles are mainly used to adsorb, grasp, or transport materials. For example, in the surface mount production line of electronic components, nozzles use vacuum adsorption to pick up tiny electronic components from the tray and then accurately place them on the designated position on the circuit board. In vacuum handling equipment, nozzles can adsorb objects of various shapes and materials to realize the handling and transfer of materials.
[0003] Traditional suction nozzles suffer from poor stability during use. When adsorbing materials, they may fail to accurately align with the target position, leading to adsorption deviations. This affects subsequent processing or assembly accuracy and reduces product quality. Therefore, we propose a dual-guide-post suction nozzle. Utility Model Content
[0004] The purpose of this invention is to provide a dual-guide-post suction nozzle to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a dual-guide-post suction nozzle, comprising:
[0006] The nozzle base and the rubber pad are fixedly connected to the bottom surface of the nozzle base. Multiple air holes are opened between the nozzle base and the rubber pad, and the multiple air holes are connected to the outside. A slot is opened on the top surface of the nozzle base, and a nozzle rod is inserted into the slot. A nozzle sleeve is sleeved around the nozzle rod.
[0007] A limiting component is located between the nozzle rod and the nozzle sleeve rod, and is used to limit the nozzle sleeve rod to the periphery of the nozzle rod;
[0008] A limiting plate is fixedly connected to the periphery of the suction nozzle sleeve rod. Two guide posts are inserted into the limiting plate. Multiple buffer springs are respectively sleeved on the periphery of the two guide posts and the periphery of the suction nozzle rod, and the bottom ends of the multiple buffer springs are in contact with the top surface of the suction nozzle base.
[0009] A fixing component is located on the nozzle base and is used to restrict the limiting plate between two guide posts.
[0010] Based on the above structure, the suction rod and suction sleeve rod ensure that the suction sleeve rod can slide around the periphery of the suction rod. The limiting component ensures that the suction sleeve rod can only slide up and down around the periphery of the suction rod. The air hole and slot ensure that when the user evacuates the slot through the inner cavity of the suction sleeve rod and the inner cavity of the suction rod, the slot can generate negative pressure, allowing the slot to draw in outside air through one of the air holes, achieving the purpose of adsorption. The limiting plate and guide post ensure that the limiting plate can move up and down along the two guide posts. The fixing component ensures that the user can restrict the limiting plate between the two guide posts, allowing the limiting plate to slide only between the two guide posts. The rubber pad ensures that the rubber pad can provide an initial cushioning effect for the entire device, preventing damage to the adsorbent. The buffer springs ensure that multiple buffer springs can further provide a cushioning effect for the entire device, further preventing damage to the adsorbent.
[0011] In the above technical solution, the limiting component further includes:
[0012] A limiting groove is formed on the periphery of the nozzle rod and communicates with the inner cavity of the nozzle sleeve rod;
[0013] A limiting bolt is threaded onto the periphery of the nozzle sleeve rod, with one end of the limiting bolt penetrating the nozzle sleeve rod and extending into the limiting groove.
[0014] In this technical solution, the nozzle sleeve rod is restricted to moving only up and down around the periphery of the nozzle rod.
[0015] In the above technical solution, one end of the limiting bolt is slidably connected to the limiting groove.
[0016] In this technical solution, it is ensured that when the nozzle sleeve moves up and down, one end of the limiting bolt can slide normally within the limiting groove.
[0017] In the above technical solution, the fixing component further includes:
[0018] Two threaded grooves are formed on the top surface of the nozzle base;
[0019] Two fixing bolts are inserted into the inner cavities of the two guide posts, and the bottom ends of the two fixing bolts extend into the two threaded grooves and are threadedly connected to the two threaded grooves respectively. The top ends of the two fixing bolts extend to the outside.
[0020] In this technical solution, the two fixing bolts are used to restrict the limiting plate between the two guide posts, so that the limiting plate can only move up and down between the two guide posts.
[0021] In the above technical solution, the rubber pad is further made of rubber.
[0022] In this technical solution, it is ensured that the rubber pad will not damage the absorbent when it is pressed on it.
[0023] In the above technical solution, the slot is further connected to one of the air holes.
[0024] In this technical solution, it is ensured that when the slot generates negative pressure, the slot can adsorb the adsorbent onto the bottom surface of the rubber pad through one of the air holes.
[0025] In the above technical solution, the limiting plate is further slidably connected to the periphery of the two guide posts.
[0026] In this technical solution, it is ensured that when the limiting plate slides, the limiting plate can slide normally on the periphery of the two guide posts.
[0027] In the above technical solution, the nozzle base is further made of acetal steel.
[0028] In this technical solution, acetal has extremely high tensile strength and hardness. Its tensile strength is usually between -MPa, its bending strength can reach -MPa, its modulus is in the range of -MPa, and its strength is comparable to some metal materials. This allows the nozzle base to withstand large external forces without deformation or damage, ensuring the stability and reliability of the nozzle during operation.
[0029] The beneficial effects of this utility model are:
[0030] 1. This dual-guide-post suction nozzle, through its suction rod and suction sleeve rod, ensures that the suction sleeve rod can slide around the periphery of the suction rod. A limiting component ensures that the suction sleeve rod can only slide up and down around the periphery of the suction rod. An air hole and slot ensure that when the user evacuates air from the inner cavity of the suction sleeve rod and the inner cavity of the suction rod, the slot generates negative pressure, allowing air to be drawn in through one of the air holes, achieving adsorption. A limiting plate and guide posts ensure that the limiting plate can move up and down along the two guide posts. A fixing component allows the user to confine the limiting plate between the two guide posts, ensuring that the limiting plate can only slide between them. This solves the problem of poor nozzle stability during use, where the nozzle may not accurately align with the target position when adsorbing materials, leading to adsorption position deviations that affect subsequent processing or assembly accuracy and reduce product quality.
[0031] 2. This dual-guide-post suction nozzle, through the setting of rubber pads, ensures that the rubber pads can provide an initial cushioning effect for the entire device, preventing the entire device from damaging the adsorbent. Through the setting of buffer springs, multiple buffer springs ensure that the entire device can provide a further cushioning effect for the entire device, further preventing the entire device from damaging the adsorbent.

[0047] When the nozzle sleeve 7 is fitted into a suitable position on the periphery of the nozzle rod 5, the user inserts the limiting bolt 8 into the nozzle sleeve 7, and then the user uses a tool to rotate the limiting bolt 8 so that one end of the limiting bolt 8 is subjected to the action of the thread of the nozzle sleeve 7 and inserted into the limiting groove 6, ensuring that the nozzle sleeve 7 is restricted to moving only up and down on the periphery of the nozzle rod 5.
[0048] Example 3: This example provides a dual-guide post suction nozzle, which, in addition to the technical solutions of the above examples, also has the following technical features: one end of the limiting bolt 8 is slidably connected to the limiting groove 6.

[0053] The user manually inserts two fixing bolts 11 from above the limiting plate 9 into the two guide posts 12, and then through the guide posts 12 into the two threaded grooves 10. The user then uses a tool to rotate the two fixing bolts 11, so that the bottom ends of the two fixing bolts 11 are subjected to the threads of the two threaded grooves 10 and move downwards. This ensures that the two fixing bolts 11 can restrict the limiting plate 9 between the two guide posts 12, allowing the limiting plate 9 to move up and down only between the two guide posts 12.

Its tensile strength is usually between 60-70MPa, its bending strength can reach 80-100MPa, and its modulus is in the range of 2500-2800MPa.

[0062] Working principle:
[0063] In use, the user fixes the rubber pad 2 to the bottom surface of the nozzle base 1 with adhesive. Then, the user inserts the nozzle rod 5 into the slot 4, and then places one of the buffer springs 13 around the nozzle rod 5. Next, the user holds the limiting plate 9 and places the nozzle sleeve 7 around the nozzle rod 5. When the nozzle sleeve 7 is in the appropriate position on the nozzle rod 5, the user inserts the limiting bolt 8 into the nozzle sleeve 7. The user then uses a tool to rotate the limiting bolt 8, causing one end of the limiting bolt 8 to be inserted into the limiting groove 6 by the thread of the nozzle sleeve 7. At this point, the nozzle sleeve 7 is restricted to moving only up and down around the nozzle rod 5. Finally, the user places the two guide posts 12 on the nozzle base 1. The top surface is positioned appropriately, and then the other two buffer springs 13 are respectively fitted onto the two guide posts 12. Then, the user manually inserts the two fixing bolts 11 from above the limiting plate 9 into the two guide posts 12, and through the two guide posts 12 into the two threaded grooves 10. Then, the user uses a tool to rotate the two fixing bolts 11, so that the bottom end of the two fixing bolts 11 is subjected to the thread action of the two threaded grooves 10 and moves downward, so that the two fixing bolts 11 restrict the limiting plate 9 between the two guide posts 12, so that the limiting plate 9 can only move up and down between the two guide posts 12, ensuring that the suction nozzle sleeve 7 will be affected by the limiting plate 9 and can only move up and down, preventing instability.
