DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 4 , a chip FT test equipment that is easy to sort, including an FT test equipment body 1 and a chip test seat 2 arranged on the FT test equipment body 1, a vertical plate 6 is fixedly connected to the FT test equipment body 1, and the chip test seat 2 can be automatically opened and closed. The relevant automation equipment in the prior art can be used, and the relevant structure in the present application can also be used. For example, a vertical pole 3 is fixedly connected to the side of the FT test equipment body 1 away from the vertical plate 6, a first electric push rod 4 is fixed to the upper end of the vertical pole 3, a connecting rod 5 is rotatably connected to the output end of the first electric push rod 4, and the other end of the connecting rod 5 is rotatably connected to the upper cover of the chip test seat 2, the upper cover of the chip test seat 2 is opened by contracting the first electric push rod 4, and the upper cover of the chip test seat 2 is tightened by extending the first electric push rod 4 to press the chip, thereby preventing inaccurate measurement of the FT test equipment body 1;

[0030] An isosceles triangle adsorption drive mechanism is arranged on one side of the vertical plate 6 facing the chip test seat 2, and a belt 21 is arranged on the outer side of the adsorption drive mechanism for transmission, and a vacuum adsorption assembly 33 is arranged at the middle of the lower end of the belt 21. There are many options for the vacuum adsorption assembly 33, such as a vacuum adsorption platform, a vacuum adsorption plate, a vacuum sponge adsorption, etc., but it is required to meet the requirement that the size of the vacuum adsorption assembly 33 is smaller than the size of the chip in the chip test seat 2, so as to be able to penetrate into the chip test seat 2 to adsorb the chip out;

[0031] The adsorption drive mechanism can drive the belt 21 to transmit in forward and reverse directions, and can drive the vacuum adsorption assembly 33 to move downward, so that the adsorption drive mechanism is deformed into a pentagon, so that only the vacuum adsorption assembly 33 can contact the chip in the chip test seat 2, so that the vacuum adsorption assembly 33 can adsorb the chip in the opened chip test seat 2, that is, the tested chips can be sorted through two different transmission directions of forward and reverse directions.

[0032] Specifically, a first round rod 7 is fixedly connected to the upper end of the vertical plate 6, a second electric push rod 9 is fixedly connected to the middle part of the vertical plate 6, a connecting plate 10 is fixedly connected to the output end of the second electric push rod 9, a sleeve 8 and a bottom rod 13 are fixedly connected to the upper and lower ends of the connecting plate 10, respectively. In order to further enhance the stability of the bottom rod 13, a first insertion rod 12 is fixedly connected to the side of the bottom rod 13, the first insertion rod 12 is slidably connected to the vertical plate 6, the sleeve 8 is slidably connected to the outer side of the first round rod 7, and the above-mentioned adsorption driving mechanism is directly or indirectly connected to the sleeve 8 and the bottom rod 13, so that the second electric push rod 9 can drive the adsorption driving mechanism to move horizontally to avoid interfering with the automatic opening and closing of the chip test seat 2.

[0033] Specifically, the adsorption drive mechanism includes a guide mechanism arranged at both ends of the bottom rod 13 and used to guide the movement of the guide shaft 15, an upper pulley 11 rotatably connected to the outer side of the sleeve 8, a lower pulley 18 rotatably connected to the outer side of the guide shaft 15, a reversing drive assembly for driving the upper pulley 11 to rotate, and a three-fold plate rotatably connected to the guide shaft 15. The belt 21 is wrapped around the three-fold plate, the lower pulley 18 and the upper pulley 11 to form a stable transmission structure. The reversing drive assembly is also used to drive the middle part of the three-fold plate to move downward. When the adsorption drive mechanism is an isosceles triangle, the lower end surface of the three-fold plate is flush, and regardless of the shape change of the adsorption drive mechanism, the belt 21 can always fit the lower end surface of the three-fold plate.

[0034] Specifically, the three-fold plate includes a second bottom plate 20 and a first bottom plate 19 rotatably connected to both ends of the second bottom plate 20, and one end of the first bottom plate 19 away from the second bottom plate 20 is rotatably connected to the outer side surface of the guide shaft 15, wherein the upper end surface of the middle part of the second bottom plate 20 is much lower than the upper end surface of the first bottom plate 19, thereby increasing the rotation amplitude of the first bottom plate 19 and the second bottom plate 20 when the three-fold plate is folded, that is, increasing the distance that the second bottom plate 20 can move downward.

[0035] Specifically, the guiding mechanism includes an arc-shaped guide rail frame 14 fixed at both ends of the bottom rod 13 and a pressure rod 22 fixedly connected to the arc-shaped guide rail frame 14. The setting of the pressure rod 22 can limit the rotation angle of the second bottom plate 20. The guide shaft 15 is slidably connected in the arc-shaped guide rail frame 14. The curvature of the arc-shaped guide rail frame 14 is set according to the movement trajectory of the guide shaft 15 when the shape of the adsorption drive mechanism changes, which effectively plays a guiding role. When the adsorption drive mechanism is an isosceles triangle, the lower end surface of the three-fold plate is flush, and the upper end surface of the first bottom plate 19 is in contact with the pressure rod 22, and the guide shaft 15 is in contact with the upper end of the arc-shaped guide rail frame 14.

[0036] Specifically, the guide mechanism also includes an arc rod 16 fixedly connected to the guide shaft 15 and having the same arc as the arc guide frame 14, and a spring 17 arranged between the arc rod 16 and the upper end of the arc guide frame 14. The arc rod 16 is slidably connected to the upper end of the arc guide frame 14. Figure 1-Figure 4 The state of the spring 17 shown in the figure is a compressed state. The purpose of setting the spring 17 and the arc rod 16 is to facilitate the resetting of the guide shaft 15, and indirectly to facilitate the resetting of the first base plate 19 to the horizontal. The setting method of the spring 17 is: the upper end of the spring 17 is fixedly connected to the upper end of the arc rod 16, and the lower end of the spring 17 is fixedly connected to the lower end of the arc guide rail frame 14.

[0037] Specifically, the direction-changing drive assembly includes an electric telescopic rod 27 fixedly connected to the lower half of the outer side surface of the end of the sleeve 8 away from the vertical plate 6, a gear ring 32 fixedly connected to the side of the upper pulley 11 away from the vertical plate 6, a double-sided rack 26 rotatably connected to the output end of the electric telescopic rod 27 and capable of meshing with the gear ring 32 on both sides, and a direction-changing assembly, such as Figure 2 As shown, the two surfaces of the double-sided rack 26 with teeth need to be adjacent, and when the teeth on one surface are engaged with the gear ring 32, the teeth on the other surface need to face away from the upper pulley 11. When the electric telescopic rod 27 is extended, it is used to push the second base plate 20 to move downward. When the electric telescopic rod 27 is contracted, it is used to drive the double-sided rack 26 to move upward and drive the gear ring 32 to rotate. The change-of-direction assembly is used to drive the double-sided rack 26 to rotate to the other side of the gear ring 32 to engage with the gear ring 32. In addition, when the adsorption drive mechanism is an isosceles triangle, the upper end of the double-sided rack 26 does not engage with the gear ring 32 to prevent the double-sided rack 26 from driving the gear ring 32 when the electric telescopic rod 27 is extended. When the adsorption drive mechanism is reset to an isosceles triangle and the electric telescopic rod 27 is contracted, the double-sided rack 26 begins to engage with the gear ring 32.

[0038] Specifically, the direction-changing component includes a driven gear 28 rotatably connected to the output end of the electric telescopic rod 27 and a gear driving component for driving the driven gear 28 to rotate. When the electric telescopic rod 27 is extended, the driven gear 28 will move downward against the first base plate 19. The gear driving component is arranged on the upper end surface of the second base plate 20, and the lower end of the double-sided rack 26 is fixedly connected to the outer side of the driven gear 28. The number of times the direction-changing component is used is related to the amount of high-quality and low-quality test chips. For example, if the high-quality rate is 95%, the direction-changing component only needs to be started 10% of the total test amount.

[0039] Specifically, the gear drive assembly includes a motor 29 fixedly connected to the upper end surface of the second base plate 20 and a driving gear 30 fixedly connected to the output shaft of the motor 29. The height of the driving gear 30 is much higher than the height of the driven gear 28, so that the driving gear 30 is always engaged with the driven gear 28. In addition, in order to ensure the stability of the motor 29 driving the driving gear 30, a stabilizing frame 31 is fixed on the second base plate 20, and the upper end of the driving gear 30 is rotatably connected to the upper end of the stabilizing frame 31.

[0040] Specifically, in order to ensure the stability of the double-sided rack 26 when it moves, a second plug rod 25 is slidably connected to the upper end of the double-sided rack 26, and a ring 24 is fixedly connected to the upper end of the second plug rod 25. The side of the sleeve 8 facing away from the electric telescopic rod 27 is fixedly connected to the second round rod 23, and the ring 24 is rotatably connected to the upper end of the second round rod 23, so that it can be more stable when the changing direction assembly drives the double-sided rack 26 to change direction.

[0041] Working principle: As for the working principle, only the steps of taking out and sorting the chip from the chip test seat 2 are described. As for how to place the chip in the chip test seat 2, in addition to the corresponding settings in the prior art, the chip can also be adsorbed into the chip seat by using an adsorption drive mechanism. The specific settings are similar to taking the chip out of the chip test seat 2.

[0042] When taking the chip out of the chip test seat 2, first control the electric telescopic rod 27 to extend, the driven gear 28 will press down the second bottom plate 20, the second bottom plate 20 will drive the first bottom plate 19 to move downward, the first bottom plate 19 will tilt, and at the same time drive the guide shaft 15 to slide downward along the arc guide frame 14, and at the same time drive the arc rod 16 to squeeze the spring 17. With the deformation of the adsorption drive mechanism, the belt 21 will also change. When the vacuum adsorption assembly 33 fits the chip, start the vacuum adsorption assembly 33 to start adsorption. After adsorption, control the electric telescopic rod 27 to contract, and under the action of the rebound force of the spring 17, the guide shaft 15 will be driven to reset, and then the first bottom plate 19 and the second bottom plate 20 will be driven to reset;

[0043] After the reset is completed, when the chip is of good quality, the electric telescopic rod 27 is directly controlled to continue to shrink, thereby driving the driven gear 28 to move upward along the driving gear 30, and at the same time driving the double-sided rack 26 to move upward, so that the double-sided rack 26 engages the gear ring 32, thereby driving the gear ring 32 to rotate, thereby driving the upper pulley 11 to rotate, and then driving the belt 21 to start transmission. With the transmission of the belt 21, the vacuum adsorption component 33 will be driven to move to one side. When it moves to a certain position, the vacuum adsorption component 33 is closed to collect the chip;

[0044] After the reset is completed, if the chip is defective, the motor 29 needs to be controlled to start, drive the driving gear 30 to rotate, and then drive the driven gear 28 and the double-sided rack 26 to rotate, and the double-sided rack 26 drives the second insertion rod 25 and the ring 24 to rotate, so that the other side of the double-sided rack 26 is ready to mesh with the gear ring 32, and then the electric telescopic rod 27 continues to retract according to the steps of the previous section to collect the chips;

[0045] After the collection is completed, the electric telescopic rod 27 is controlled to extend, and the electric telescopic rod 27 will also drive the driven gear 28 and the double-sided rack 26 to move downward, and at the same time drive the gear ring 32 to rotate in the opposite direction, thereby driving the vacuum adsorption assembly 33 to reset;

[0046] For collecting the chips, corresponding transmission collection belts may be provided under the belts 21 on both sides of the vacuum adsorption assembly 33, or a collection box may be provided, which may be provided specifically according to the requirements.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
