Technical Field

[0001] This utility model relates to the field of device packaging and testing technology, and more specifically, to an automatic testing machine nozzle device. Background Technology

[0002] In the production of electronic devices, integrated circuit automatic testing machines are frequently used. These machines are used to test the integrity of integrated circuit functions and represent the final step in the integrated circuit manufacturing process to ensure the quality of integrated circuit production.

[0003] For (integrated circuit) automatic testing machines, in order to achieve the required functions, a nozzle assembly is usually required to pick up and move products (circuit board products, such as IC chips). However, the nozzle assemblies on existing automatic testing machines are directly connected and driven by drive components (such as cylinders, motors, etc.). Because the nozzle descends at a relatively fast speed and there are no good buffer components in the nozzle assembly, the hard nozzle in the nozzle assembly can easily cause excessive impact on the product surface, resulting in damage to the product surface (especially the solder balls on the product surface).

[0004] Based on the above technical problems, there is an urgent need for a solution that can effectively protect the safety of the product surface during the product suction process of the automatic testing machine's suction nozzle device. Utility Model Content

[0023] Beneficial effects:

[0024] The automatic testing machine nozzle device provided by this utility model provides a strong buffering effect when the nozzle contacts the product by setting a first elastic connector between the transmission shaft and the drive assembly and a second elastic connector between the transmission shaft and the nozzle assembly.

In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0033] Figure 1 The exploded structure of the automatic testing machine nozzle device provided by this utility model is shown. Figure 2 The exploded partial enlargement of the nozzle device for the automatic testing machine provided by this utility model is shown.

[0034] Combine Figure 1 and Figure 2 As shown in the figure, the automatic testing machine nozzle device provided in the embodiment of the present invention includes a nozzle assembly and a drive assembly for providing driving force to the nozzle assembly. In order to realize the connection between the nozzle assembly and the drive assembly, a transmission shaft 4 is provided between the drive assembly and the nozzle assembly. The upper end of the transmission shaft 4 is connected to the drive assembly through a first elastic connector, and the lower end of the transmission shaft 4 is connected to the nozzle assembly through a second elastic connector.

[0035] In actual operation, the drive assembly drives the drive shaft to move through the first elastic connector, and the drive shaft drives the nozzle assembly to move through the second elastic connector, thereby completing the function of the nozzle approaching and moving away from the product, realizing the suction and downward movement of the product. It should be noted that the nozzle device of the automatic testing machine provided by this utility model, because a first elastic connector is set between the drive assembly and the drive shaft 4, and a second elastic connector is set between the drive shaft 4 and the nozzle assembly, can provide buffer components for the nozzle assembly at two positions. This can provide a strong buffering effect when the nozzle assembly contacts the product, avoiding the impact on the product surface caused by the rapid descent of the nozzle, thereby effectively preventing the hard nozzle from crushing the solder balls on the product surface and avoiding functional damage to the product.

[0036] In one specific embodiment of this utility model, in order to achieve the buffering effect provided by the first elastic connector, the first elastic connector may include a first spring 3, a first connecting part 41 is formed at the upper end of the transmission shaft 4, the lower end of the first spring 3 is connected to the first connecting part 41, and the upper end of the first spring 3 is connected to the drive assembly, thereby realizing the elastic connection between the drive assembly and the transmission shaft 4.

[0037] Of course, in the actual manufacturing process, other elastic connectors can also be used to provide the first spring 3, such as elastic sheets.

[0038] Furthermore, the drive assembly, to achieve its driving effect, can include a cylinder 1 and a drive block 8. The output end 11 of the cylinder 1 is connected to the drive block 8, and the upper end of the first spring 3 is connected to the drive block 8. Of course, in actual manufacturing, the cylinder 1 can also be replaced by other power components, such as a hydraulic cylinder, a motor (which can be used with a lead screw mechanism), etc.

[0039] In addition, to ensure that the transmission shaft 4, connected to the cylinder 1 via the first elastic element, can move back and forth in the desired direction with the drive block 8, the automatic testing machine nozzle device provided by this utility model may further include a guide positioning rod 2; wherein, the drive block 8 and the transmission shaft 4 are both slidably connected to the guide positioning rod 2; the first spring 3 is sleeved on the guide positioning rod 2 and connected between the drive block 8 and the transmission shaft 4. In this way, the movement of the transmission shaft 4 can be limited and guided, effectively improving the transmission stability of the automatic testing machine nozzle device provided by this utility model during use.

[0040] It should be noted that the upper end of the guide positioning rod 2 needs to be synchronized with the outer shell of the cylinder 1 to achieve the required transmission effect. Therefore, the upper end of the guide positioning rod 2 can be fixedly connected to the outer shell of the cylinder 1, or the upper end of the guide positioning rod 2 can be directly connected to the position on the automatic testing machine that is synchronized with the outer shell of the cylinder 1.

[0041] In another specific embodiment of this utility model, in order to achieve the buffering effect provided by the second elastic connector, the second elastic connector may include a second spring 5, which is connected between the drive shaft 4 and the suction nozzle assembly; of course, in the actual manufacturing process, other elastic connectors may also be used to provide the second spring 5, such as elastic sheets.

[0042] Specifically, to achieve an elastic connection between the nozzle assembly and the drive shaft 4, the nozzle assembly includes a nozzle seat 6, the upper end of which is movably connected to the drive shaft 4; and a baffle 62 for limiting the second spring 5 is formed in the middle of the nozzle seat 6, and a second connecting part for fixing the second spring 5 is provided at the lower end of the drive shaft 4; wherein, the lower part of the second spring 5 is sleeved on the nozzle seat 6 and limited above the baffle 62, and the upper end of the second spring 5 is connected to the second connecting part, thereby achieving an elastic connection between the nozzle assembly and the drive shaft 4.

[0043] More specifically, to achieve the movable connection between the upper end of the nozzle seat 6 and the drive shaft 4, a cavity for the upper part of the nozzle seat 6 to extend into can be formed inside the drive shaft 4. An opening communicating with the cavity is provided at the bottom of the drive shaft 4, and the upper end of the nozzle seat 6 extends into the cavity through the opening. Furthermore, the second elastic connector also needs to include a positioning pin 42. An elongated hole 61 for the positioning pin 42 to pass through is provided on the part of the nozzle seat 6 that is located in the cavity, and a positioning hole communicating with the cavity is provided on the outer wall of the drive shaft 4. The positioning hole is adapted to the positioning pin 42. In actual operation, the positioning pin 42 needs to pass through the positioning hole and the elongated hole 61 in sequence. At this time, due to the existence of the elongated hole 61, a certain amount of leeway can be provided for the upper part of the nozzle seat 6 to move up and down in the cavity, so that the upper end of the nozzle seat 6 can be movably connected with the drive shaft 4. Of course, by setting positioning pins 42, positioning holes, elongated holes 61, etc., not only can the upper end of the nozzle seat 6 be connected to the drive shaft 4, but the nozzle assembly can also be replaced very conveniently, avoiding the accuracy error caused by replacing the entire automatic testing machine nozzle device.

[0044] In addition, to enable the suction assembly to pick up products, the suction assembly may also include a suction head 7 connected below the suction head 6. A suction cavity is formed inside the suction head 7, and a suction mouth communicating with the suction cavity is provided at the bottom of the suction head 7. The suction mouth is a long and thin needle-shaped suction mouth, which can effectively reduce the contact area with the product surface and prevent dirt from the product surface from sticking to the suction head 7.

[0045] In addition, a suction nozzle pin 71 adapted to the suction nozzle opening can be set in the suction cavity, with the suction nozzle pin 71 corresponding vertically to the suction nozzle opening. In actual use, when a negative pressure is generated in the suction cavity, the suction nozzle pin 71 moves upward and disengages from the suction nozzle opening, thereby enabling the suction nozzle opening to pick up the product. When the negative pressure in the suction cavity is eliminated (positive pressure can be introduced), the suction nozzle pin 71 moves downward and blocks the suction nozzle opening, so that the suction nozzle opening loses its ability to pick up the product and better separates the product surface.

[0046] As per the above reference Figure 1 and Figure 2An automatic testing machine nozzle device according to the present invention has been described by way of example. However, those skilled in the art should understand that various modifications can be made to the automatic testing machine nozzle device proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
