DETAILED DESCRIPTION

[0035] The following is a more detailed description of a quick-connect nozzle and its auxiliary wrench according to the present invention, with reference to schematic diagrams. These diagrams illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0036] For the sake of clarity, not all features of actual embodiments are described. In the following description, well-known functions and structures are not described in detail because they would clutter the present invention with unnecessary detail. It should be understood that in the development of any actual embodiment, numerous implementation details must be made to achieve the developer's specific goals, such as adapting from one embodiment to another to accommodate system or business constraints. Furthermore, it should be understood that such development work may be complex and time-consuming, but is nevertheless a routine undertaking for those skilled in the art.

[0037] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0038] As mentioned in the background, most existing automated robotic arms use suction heads that are installed and fixed with screws to facilitate material handling. When changing to different product sizes, existing suction head designs require frequent replacement of matching suction heads, a process that is both time-consuming and extremely inefficient. Furthermore, the complex assembly and disassembly process can cause significant inconvenience to operators, increasing their workload.

[0039] In view of this, if Figure 1 and Figure 2 As shown, the utility model provides a quick-connect suction head, including a fixing device 1 and a movable suction head device 2; a fixing joint is provided on the top of the fixing device 1, and the fixing joint 11 is connected to an external robotic arm. The bottom edge of the fixing device 1 is provided with a first card slot 14 extending inward, and the end of the first card slot 14 is provided with a groove; partially exposed fixing shafts 22 are symmetrically provided at both ends of the movable suction head device 2, and the exposed fixing shaft 22 is engaged with and separated from the groove at the end of the first card slot 14 to achieve rapid installation and removal of the movable suction head device 2 from the inside of the fixing device 1.

[0040] Specifically, such as Figure 3 and Figure 4 As shown, the movable suction head device 2 includes a suction nozzle piston 21, a sealing ring 23 and a fixed shaft 22; and a first flange 211 is provided at the bottom of the suction nozzle piston 21, and the first flange 211 is used to fit the device for adsorbing the chip. An annular second groove 212 is provided at a distance from the end of the suction nozzle piston 21 away from the first flange 211; the sealing ring 23 is snapped into the second groove 151. Using the sealing ring 23 snapped into the second groove 212 can ensure that the sealing ring 23 is fixed in the appropriate position to prevent it from moving or falling out during operation, thereby ensuring the sealing effect of the installation between the movable suction head device 2 and the fixing device 1. Secondly, through the design of the sealing ring 23, the vacuum performance is ensured to be stable during the process of adsorbing and releasing the chip, while avoiding wear of the fixing device 1 and the movable suction head device 2, thereby extending the service life of the product.

[0041] In this embodiment, if Figure 4 As shown, a first hole groove 213 is provided between the first flange 211 and the second slot 151. The first hole groove 213 horizontally crosses the interior of the suction nozzle piston 21. The fixed shaft 22 is connected to the suction nozzle piston 21 after passing through the first hole groove 213, and both ends of the fixed shaft 22 are partially exposed to the outside of the suction nozzle piston 21.

[0042] In this embodiment, if Figure 5The top of the fixing device 1 is provided with a fixing joint 11, and the fixing joint 11 is used to connect to an external robotic arm. The bottom edge of the fixing device 1 is provided with a first card slot 14 extending inward, and the end of the first card slot 14 is provided with a groove; the first card slot 14 is L-shaped, and the number of the first card slots 14 is at least two, and they are arranged in sequence at the same distance at the bottom edge of the movable suction head device 2. The number of the first card slots 14 is schematically shown as two in the figure.

[0043] In this embodiment, if Figure 6 As shown, a cavity is provided in the fixing device 115, and a spring is provided in the cavity 15. The movable suction head device 2 squeezes the spring 12 upward, so that the partially exposed fixed shaft 22 is rotated and engaged with and separated from the groove at the end of the first slot 14. The spring 12 is spiral in shape, and there is a first gap between each circle of the spiral. The shape of the spring 12 enables it to compress or stretch when subjected to force and provide elastic force, thereby absorbing the impact force of the movable suction head device 2 during installation or removal, reducing damage to the device and extending its service life. In addition, squeezing the spring 12 to achieve engagement and separation between the fixed shaft and the groove at the end of the first slot 14 simplifies the operation process, allowing the operator to easily perform installation and removal.

[0044] In this embodiment, if Figure 6-9 As shown, a fixing screw 13 is further provided in the cavity 15. After passing through the spring, the fixing screw 13 is threadedly connected to the second hole 151 at the top of the cavity 15. The fixing screw 13 fixes the spring 12 in the cavity 15, ensuring that the spring remains stable when subjected to external forces, preventing the spring 12 from being displaced or falling off, thereby improving the stability of the overall structure.

[0045] In another aspect of this embodiment, Figure 10 and Figure 11 As shown, the present invention also provides an auxiliary wrench 3 for installing and removing the quick-connect nozzle. A third slot 31 is provided on one side of the auxiliary wrench 3. The third slot 31 is used to guide and secure the movable nozzle assembly 2 at the bottom of the quick-connect nozzle. The third slot 31 includes symmetrically arranged fourth slots 311 on either side. Fixed shafts exposed on either side of the movable nozzle assembly 2 can be respectively engaged in the fourth slots 312.

[0046] Furthermore, the third engaging slot 31 also includes a fifth engaging slot 312 disposed in the middle thereof. The opening of the fifth engaging slot 312 is circular and is used to further guide and secure the first flange 211 at one end of the movable suction head assembly 2. The cooperation between the auxiliary wrench 3 and the movable suction head assembly 2 enables quick installation and removal of the movable suction head assembly 2, thereby improving work efficiency and convenience of maintenance.

[0047] In this embodiment, the installation method of the movable suction head device 2 and the fixing device 1 is as follows:

[0048] 1. Installation of auxiliary wrench 3 and movable suction head device 2

[0049] The bottom of the movable suction head device 2 is clamped into the third clamping groove 31 of the auxiliary wrench 3. At this time, the fixed shaft 22 exposed on both sides of the movable suction head device 2 is clamped into the fourth clamping groove 311, and the first flange 211 at one end of the movable suction head device 2 is clamped into the fifth clamping groove 312.

[0050] 2. Installation of the movable suction head device 2 and the fixing device 1

[0051] After the auxiliary wrench 3 and the movable suction head assembly 2 are installed, the end of the movable suction head assembly 2 away from the first flange 211 is pointed upward, and the spring inside the fixing assembly 1 is pressed upward. At this time, the fixed shafts 22 exposed at both ends of the movable suction head assembly 2 correspond to the entrances of the first retaining grooves 14 on both sides. The movable suction head assembly 2 is then rotated in the horizontal direction of the first retaining grooves 14, so that the exposed fixed shafts 22 are engaged in the first retaining grooves 14, thereby completing the installation of the movable suction head assembly 2 and the fixing assembly 1. In addition, the sealing ring 23 is also engaged in the fixing assembly along with the upper end of the movable suction head assembly, ensuring a sealing effect after installation.

[0052] Furthermore, the method for disassembling the movable suction head assembly 2 from the fixing device 1 is as follows: Similarly, the auxiliary wrench 3 is attached to the lower end of the movable suction head assembly 2 using the aforementioned method for attaching the auxiliary wrench 3 to the movable suction head assembly 2. After the auxiliary wrench 3 and the movable suction head assembly 2 are attached, the spring inside the fixing device 1 is squeezed upward, and then the auxiliary wrench 3 is rotated in a direction opposite to the horizontal extension of the first engaging slot 14. This causes the auxiliary wrench 3 to rotate the movable suction head assembly 2, completing the removal from the fixing device 13. Finally, the movable suction head assembly 2 is separated from the auxiliary wrench 3.

[0053] In summary, in a quick-connect suction head provided by an embodiment of the present invention, a first slot 14 is provided on the bottom edge of the fixing device 1, and a groove is provided at the end of the first slot 14. By engaging and disengaging the groove at the end of the first slot 14 with the fixed shaft 22 exposed at both ends of the movable suction head device 2, the movable suction head device 2 can be quickly installed and removed from the inside of the fixing device 1, thereby improving work efficiency. Secondly, by quickly replacing the movable suction head device 2, the quick-connect suction head has stronger compatibility to adapt to chips of different sizes and specifications. At the same time, the quick-connect suction head adopts a locking mechanism to reduce the use of complex components, making the installation and removal process simpler and faster, reducing the operating difficulty of the staff and improving production efficiency, thereby improving the efficiency and stability of the pick and place automated translation model in semiconductor FT testing.

[0054] Furthermore, the design of the spring 12 within the fixing device 1 provides elastic force for the engagement and disengagement of the fixed shaft 22 with the groove at the end of the first engaging slot 14. By compressing the spring 12, the operation process is simplified, allowing the operator to easily install and remove the device. Furthermore, the design of the sealing ring 23 ensures the sealing performance of the fixing device 1 and the movable suction head device 2, improving the operating stability of the suction head while preventing wear on the fixing device 1 and the movable suction head device 2, thereby extending the product's service life.

[0055] Furthermore, an auxiliary wrench 3 is provided, which, through the design of the third slot 31, makes the disassembly process more convenient and safer. When changing to a different size of product, existing nozzle designs frequently require the replacement of different nozzles by screws. However, the auxiliary wrench 3 of the present invention makes it easier for the operator to install and remove quick-connect nozzles, eliminating the need for complex tools or skills, reducing the difficulty of operation, and also facilitating the maintenance and care of different nozzles.

[0056] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any way. Any person skilled in the art who, without departing from the scope of the present invention, makes any equivalent substitution, modification, or other variation to the technical solution and technical content disclosed herein shall be deemed to fall within the scope of the present invention and remain within the scope of protection of the present invention.
