Description

Technical Field

[0001] The utility model belongs to the technical field of memory module testing, and particularly relates to a pressing and unlocking device for memory module testing. Background Art

[0002] After the production of memory modules is completed, they usually need to undergo performance tests such as appearance inspection, curvature inspection, and aging. After the tests are completed, labels need to be attached to the memory modules, and the categories are sorted according to the test results. Finally, they can be packaged and shipped. During the testing process, the memory modules need to be pressed into the slots of the tester, and after the tests are completed, the memory modules need to be pulled out of the slots.

[0003] Currently, when memory modules need to be pressed into or taken out of the slots, automated equipment is used. When the automated equipment presses into the slots, it presses them one by one, and when taking them out, it unlocks the slots one by one, or directly pulls out the memory modules without unlocking. Pressing the memory modules into the slots one by one and unlocking the slots one by one when taking them out result in a long time for taking in and out the memory modules, and the production capacity of the equipment is relatively low. Pulling out the memory modules directly without unlocking requires the mechanical arm clamping the memory modules to increase the torque, which easily causes the memory modules to be pinched or deformed, increasing the probability of defective products. At the same time, the existing pressing and unlocking devices for memory modules are only applicable to memory modules of one length and cannot be compatible with the plugging and unplugging requirements of memory modules of different lengths. When replacing memory modules of different lengths, it is necessary to manually replace the parts of the pressing and unlocking device one by one, resulting in a long line change time in the factory. Summary of the Utility Model

[0004] In view of this, the purpose of the present utility model is to overcome the deficiencies in the prior art and provide a pressing and unlocking device for memory module testing. The present application provides the following technical solutions:

[0005] A pressing and unlocking device for memory module testing includes a pressing component, an unlocking component, a pressing and unlocking seat, and a linear motion module. The pressing and unlocking seat is connected to the linear motion module. The pressing component and the unlocking component are arranged at the bottom of the pressing and unlocking seat. The pressing component includes several pairs of pressing head components, and each pair of pressing head components is arranged at the bottom of the pressing and unlocking seat. The unlocking component includes an unlocking pressing block component and an unlocking cylinder. The unlocking cylinder is arranged at the bottom of the pressing and unlocking seat, and the unlocking pressing block component is connected to the unlocking cylinder.

[0006] In a possible embodiment, each pair of pressing head components includes two pressing heads, and the two paired pressing heads are respectively used for pressing the two ends of the memory module.

[0008] In a possible embodiment, the unlocking pressing block assembly includes an unlocking cross beam and two unlocking pressing blocks. The top of the unlocking cross beam is connected to the unlocking cylinder. The two unlocking pressing blocks are respectively arranged on both sides of the unlocking cross beam. The unlocking pressing blocks are movably connected to the unlocking cross beam. A displacement mechanism is connected to the side surface of each unlocking pressing block to adjust the relative distance between the two unlocking pressing blocks through the displacement mechanism.

[0009] In a possible embodiment, a bulletproof springboard is arranged below the unlocking cross beam. The bulletproof springboard is connected to the unlocking cross beam through a spring guide post.

[0010] In a possible embodiment, a control system is further included. The control system controls the motion logics of the linear motion module, the downward pressing assembly and the unlocking assembly respectively.

[0011] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] The downward pressing and unlocking device for memory module testing of the present utility model can realize the automatic downward pressing and unlocking of the memory module. The linear motion module drives the downward pressing and unlocking seat, and then drives the downward pressing assembly and the unlocking assembly. The downward pressing assembly includes several pairs of pressing head assemblies. During the downward pressing process, each pair of pressing head assemblies can press down a memory module, so that the present utility model can press in multiple memory modules at one time.

[0024] In the above-mentioned embodiment, as Figure 1 shown is a schematic structural diagram of the present utility model. The pressing-down and unlocking device for testing a memory module of the present utility model is applied inside a memory module tester and is installed above the tester during use. It includes a pressing-down assembly 3, an unlocking assembly 4, a pressing-down and unlocking base 2, and a linear motion module 1. The linear motion module 1 is used to achieve linear motion in the height direction. Its structure belongs to a common structure in the prior art, such as being implemented in the form of a motor, a ball screw, and a linear guide rail, or it can also be implemented by chain drive or by gear-rack drive, etc. A pressing-down slide is fixedly installed on the side of the linear motion module 1, and the pressing-down slide is fixedly connected with the pressing-down and unlocking base 2. The pressing-down assembly 3 and the unlocking assembly 4 are installed at the bottom of the pressing-down fixing base. The linear motion module 1 drives the pressing-down assembly 3 and the unlocking assembly 4 to perform linear motion in the height direction. The entire set of equipment realizes automatic control through the control system;

[0025] As Figure 2 shown is a schematic structural diagram of the pressing-down state of the pressing-down assembly 3. The pressing-down assembly 3 includes several pairs of indenter assemblies. In this embodiment, four pairs of indenter assemblies are preferably used. The four pairs of indenter assemblies can simultaneously press 4 memory modules into the slots 12. Each pair of indenter assemblies includes two indenters 5. The two indenters 5 respectively press down the two ends of the memory module, and a pressure sensor 6 is installed on each indenter 5. During the process of pressing the memory module into the slot 12, each memory module respectively collects the pressure data at both ends of the memory module and transmits it to the control system, and outputs two pressure curves to be stored in the device computer. The lifespan of the slot 12 can be judged through the change of the pressure curve, and the slot 12 can be replaced in advance without waiting until the slot 12 completely loses its function and then stopping the machine for maintenance, thus avoiding the problem that the production capacity cannot be completed due to stopping the machine for maintenance during the production process; at the same time, it can also judge the pressure difference at both ends of the memory module to automatically identify whether the memory module is pre-placed at the entrance of the slot 12 and whether the memory module is pressed into the slot 12 in parallel. When the difference exceeds the set threshold, the device stops pressing down and gives an alarm to prompt personnel to intervene, achieving the function of protecting the main board, the product, and the slot 12 from being damaged;

[0026] In an alternative solution of the above embodiment, the unlocking press block assembly includes an unlocking cross beam 7 and two unlocking press blocks 8. The top of the unlocking cross beam 7 is connected to the unlocking cylinder 11. The two unlocking press blocks 8 are respectively arranged on both sides of the unlocking cross beam 7. The unlocking press blocks 8 are movably connected to the unlocking cross beam 7. A displacement mechanism 9 is connected to the side surface of each unlocking press block 8 to adjust the relative distance between the two unlocking press blocks 8 through the displacement mechanism 9. A bulletproof springboard 10 is arranged below the unlocking cross beam 7. The bulletproof springboard 10 is connected to the unlocking cross beam 7 through a spring guide post.

The two unlocking press buttons are respectively arranged on both sides of the unlocking cross beam 7, and the unlocking press block 8 is movably connected to the unlocking cross beam 7. In this embodiment, the length of the unlocking press button is increased. When it unlocks downward, it can unlock the buckles of four slots 12 at one time. At the same time, in order to solve the problem of inconsistent lengths of different types of slots 12, the manual operation complexity during product replacement is simplified. A displacement mechanism 9 is arranged on the side surface of the unlocking press block 8. The displacement mechanism 9 is used to drive the unlocking press block 8 to move on the side surface of the unlocking cross beam 7, thereby changing the relative distance between the two unlocking press blocks 8, so as to meet the use of slots 12 of different lengths. As Figure 3 shown, the displacement mechanism 9 can be a cylinder. At the same time, in this embodiment, during the unlocking process, to prevent the memory module from suddenly popping out after successful unlocking, a bulletproof springboard 10 is also arranged at the bottom of the unlocking cross beam 7. The bulletproof springboard 10 is a flexible structure, and the top is connected to the unlocking cross beam 7 through a spring and a guide post. The bulletproof springboard 10 can effectively prevent the memory module from popping out of the slot 12.
