[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0028] Please refer to the attached Figures 1 to 6 As shown, the flash memory chip testing device in the embodiment of the present utility model includes a bottom plate 1. A test seat 2 is fixedly connected to the upper end surface of the bottom plate 1. An upper cover 4 is arranged above the test seat 2. An indenter 12 is connected to the lower end surface of the upper cover 4. Guide rods 6 are fixedly connected to both sides of the upper end surface of the bottom plate 1. Guide sleeves 11 are fixedly connected to both sides of the upper cover 4. The guide sleeves 11 are slidably sleeved on the guide rods 6. When in use, the upper cover 4 can move stably along the guide rods 6, so as to accurately cooperate with the test seat 2.
[0029] The test seat 2 includes a seat body 21. A test groove 22 is opened inside the upper end surface of the seat body 21. A lifting component 3 is arranged inside the test groove 22. The arranged lifting component 3 facilitates the taking and placing of the chip.
[0030] The lifting component 3 includes a frame 31. Connecting brackets 32 are fixedly connected to both sides of the frame 31. The connecting brackets 32 extend into the interior of the base body 21 and are slidably connected to the base body 21. A spring piece 34 is fixedly connected between the lower end of the connecting bracket 32 and the inner bottom of the base body 21. Before testing, the frame 31 of the lifting component 3 is in a popped-up state. A stepped groove is formed on the inner side of the frame 31. The flash memory chip to be tested is clamped in the groove of the frame 31. Then, the upper cover 4 is pressed down. Through the contact between the pressing rod 13 and the protruding rod 33, the frame 31 is driven to move downward, so that the chip pins can accurately contact the pin holes in the test slot 22, ensuring the test effect and not easily damaging the pins. In addition, after the test is completed, when the upper cover 4 is opened, the frame 31 of the lifting component 3 can rise through the elastic force of the internal spring piece 34, thereby lifting the chip out of the test slot 22, making it convenient to pick up and place the chip and more convenient to use.
[0031] A locking component 5 is connected to the upper end surface of the upper cover 4. The locking component 5 includes a connecting seat 51 fixedly connected to the upper cover 4. Rack bars 53 are alternately slidably connected to both sides inside the connecting seat 51. One ends of the two rack bars 53 both extend out of the connecting seat 51 and are fixedly connected with bevel lock heads 54. Lock holes 7 are formed on the lower sides of the two guide rods 6. The two lock holes 7 correspond to the positions of the two bevel lock heads 54 respectively. A rotary knob 52 is rotatably connected to the upper end surface of the connecting seat 51. The lower end of the rotary knob 52 extends into the interior of the connecting seat 51 and is fixedly connected with a gear 55. The gear 55 is meshed with the two rack bars 53. The provided locking component 5 is used to stably press the upper cover 4 against the test base 2. Specifically, the upper cover 4 is pressed down on the test base 2. Then, the rotary knob 52 is rotated, so as to drive the two rack bars 53 to move through the gear 55, making the two bevel lock heads 54 insert into the lock holes 7. Since the end of the bevel lock head 54 is beveled, the more the bevel lock head 54 extends into the lock hole 7, the closer the upper cover 4 is pressed against the test base 2.
[0032] The upper end of the connecting bracket 32 is fixedly connected with a protruding rod 33 that extends out of the base body 21. Pressing rods 13 are fixedly connected to the four corners of the lower end of the upper cover 4. The positions of the pressing rods 13 correspond to the positions of the protruding rods 33 one by one. By setting the contact between the pressing rods 13 and the protruding rods 33, the frame 31 is driven to press down. In addition, when the upper cover 4 is opened, before the protruding rod 33 rises to the highest point, the pressing rod 13 will always be in contact with the protruding rod 33, thereby preventing the chip from being bounced up due to the rapid popping of the spring piece 34.
[0033] A cavity 14 is formed inside the lower end surface of the upper cover 4. The upper end of the pressing head 12 extends into the cavity 14 and is slidably connected to the cavity 14. A plurality of second springs 15 are fixedly connected between the upper end of the upper cover 4 and the inner wall of the cavity 14. By setting the second springs 15, the pressing head 12 can stretch within a certain range. When in use, the pressing head 12 can closely fit with the chip, ensuring that the chip is stably in contact with the test slot 22 during testing.
[0034] A through groove 8 is formed at the lower end of the guide rod 6. A buffer sleeve 9 is slidably sleeved on the outer end of the through groove 8. A first spring 10 is fixedly connected between the lower end surface of the buffer sleeve 9 and the bottom plate 1. When the upper cover 4 is pressed down, the guide sleeve 11 will contact the buffer sleeve 9 and then contact the first spring 10. The elastic force of the first spring 10 plays a buffering role, which can prevent the upper cover 4 from closing too quickly and colliding with the test base 2.
[0035] A mating groove 23 is formed on the outer side of the bottom surface of the test groove 22. The size of the mating groove 23 is matched with that of the frame 31. By providing the mating groove 23, after the frame 31 descends, it can be received into the mating groove 23, so that the chip can be stably connected to the pin holes of the test groove 22.
[0036] The above has described in detail an embodiment of the present invention, but the described content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application shall still fall within the scope covered by the patent of the present invention.
