[0002] A solid-state drive (SSD), also known as a solid-state drive (SSD), is a hard drive manufactured using an array of solid-state electronic memory chips. During the SSD assembly process, casing pressing is one of the final, crucial steps. To improve production efficiency and save manpower, modern production lines often utilize SSD casing pressing machines for this process.

[0003] Currently, common SSD casing pressing machines primarily consist of key components such as a pressing cylinder, a pressing die, a fixed die, and a control switch. During operation, a worker places the SSD product on the fixed die. Then, by activating the pressing cylinder, the pressing die and fixed die work together to press the SSD casing together. While this type of equipment simplifies the pressing process, it poses certain safety risks.

[0004] In actual operation, the equipment is activated by pressing a single start button or using an object-sensing method. This can cause the operator's hand to unconsciously reach close to the pressing cylinder to catch the material immediately after the pressing is completed. This operation method can easily cause the hand to be pinched by the pressing cylinder, resulting in serious work-related accidents. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all 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.

[0030] This application is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of this application, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, these schematic diagrams are merely illustrative and should not limit the scope of this application.

[0031] Currently, common fixed-body hard drive casing pressing machines primarily consist of a pressing cylinder, a pressing die, a fixed die, and a control switch. During operation, a worker places the fixed hard drive product on the fixed die and then activates the pressing cylinder, allowing the pressing die and fixed die to work together to press the SSD casing. However, this equipment's activation methods, such as pressing a single start button or using object sensing, can cause the operator's hand to unconsciously reach close to the pressing cylinder in order to immediately receive the material after pressing is complete. This method of operation can easily cause the operator's hand to be pinched by the pressing cylinder, resulting in serious workplace injuries.

[0032] Please refer to Figure 1 and Figure 4 In one embodiment of the present application, a pressing device for a memory is proposed, including a safety device 1, a cylinder driving device 2 and a pressing platform 3; the cylinder driving device 2 includes a piston cylinder 201, a pressing block 202 and a solenoid valve 203, the piston cylinder 201 is connected to the pressing block 202, and is used to drive the pressing block 202 to move toward the pressing platform 3; the solenoid valve 203 is electrically connected to the piston cylinder 201, and is used to drive the piston cylinder 201; the safety device 1 is arranged on the pressing block 202; wherein, the safety device 1 includes a sensing part 101 and an insulating layer 102, one end of the sensing part 101 is located inside the pressing block 202, and the other end is located outside the pressing block 202; the insulating layer 102 is provided between the pressing block 202 and the sensing part 101; the sensing part 101 is electrically connected to the solenoid valve 203; when the sensing part 101 detects an abnormal signal, the solenoid valve 203 stops driving the piston cylinder 201. By installing safety device 1 on pressing block 202, the operator's hand can be sensed while pressing block 202 is pressing the solid-state drive. When the operator's hand touches sensing portion 101, sensing portion 101 detects an abnormal signal, disconnecting the power supply to solenoid valve 203 and stopping piston cylinder 201. This prevents the piston cylinder 201 from continuously operating and pinching the operator's hand, potentially causing a serious workplace accident.

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 4As shown, in one embodiment, it includes a safety device 1, a cylinder driving device 2 and a pressing platform 3; the cylinder driving device 2 includes a piston cylinder 201, a pressing block 202 and a solenoid valve 203, the piston cylinder 201 is connected to the pressing block 202, and is used to drive the pressing block 202 to move toward the pressing platform 3; the solenoid valve 203 is electrically connected to the piston cylinder 201, and is used to drive the piston cylinder 201; the safety device 1 is arranged on the pressing block 202; wherein, the safety device 1 includes a sensing part 101 and an insulating layer 102, one end of the sensing part 101 is located inside the pressing block 202, and the other end is located outside the pressing block 202; the insulating layer 102 is provided between the pressing block 202 and the sensing part 101; the sensing part 101 is electrically connected to the solenoid valve 203; when the sensing part 101 detects an abnormal signal, the solenoid valve 203 stops driving the piston cylinder 201.

[0035] Specifically, such as Figure 1 As shown, the safety device 1 is mounted on the pressing block 202, and the cylinder drive device 2 is located above the pressing platform 3. The cylinder drive device 2 includes a solenoid valve 203, a piston cylinder 201, and a pressing block. The piston cylinder 201 is connected to the pressing block 202. The solenoid valve 203 is used to send and receive signals and is electrically connected to the piston cylinder 201 to drive the piston cylinder 201's movement. The piston cylinder 201 uses compressed air to drive the piston rod, which in turn drives the pressing block 202, which is fixed to the piston rod, to move vertically. The cylinder drive device 2 provides stable and adjustable pressure to ensure that excessive or insufficient pressure during the pressing process does not damage the SSD housing or cause a loose connection. The piston cylinder 201 is controlled by a combination of a pneumatic system and an electrical system. The operator can set the air pressure of the piston cylinder 201 on the control panel. The specific value can be set based on the material and thickness of the hard drive housing 7.

[0036] Furthermore, the pressing platform 3 is located in the central area of ​​the device and is made of high-strength material, such as steel plate, to ensure that it will not be deformed or displaced under long-term high pressure.

[0037] More specifically, if Figure 4As shown, the safety device 1 includes a sensing portion 101, an insulating layer 102, and a conductive wire 103. One end of the sensing portion 101 is located outside the pressing block 202, and the other end is located inside the pressing block 202. The end located outside the pressing block 202 can sense the operator's hand. The sensing portion 101 is made of conductive material. When the pressing block 202 is also made of conductive material, an insulating layer 102 must be provided inside the pressing block 202 to prevent the pressing block 202 and the sensing portion 101 from being made of the same conductive material and conducting electricity. The sensing portion 101 is electrically connected to the solenoid valve 203 via the conductive wire 103 and is provided with a normally closed emergency stop circuit. When the operator's hand touches the sensing portion 101, the sensing portion 101 sends an abnormal signal to the emergency stop circuit via the conductive wire 103. The emergency stop circuit then cuts off the power supply to the solenoid valve 203, causing the cylinder drive device 2 to stop working, thus preventing the pressing block 202 from continuously pressing down and pinching the operator's hand.

[0038] In one embodiment, the sensing part is provided with an emergency stop circuit; the emergency stop circuit includes a normal state and an abnormal state; when the emergency stop circuit is in the normal state, the emergency stop circuit is closed to energize the solenoid valve; when the sensing part detects an abnormal signal, the emergency stop circuit switches from the normal state to the abnormal state, the emergency stop circuit is disconnected, the solenoid valve is closed, and driving the piston cylinder is stopped.

[0039] Specifically, if Figure 7 As shown, under normal conditions, the sensing unit 101 and the solenoid valve 203 are connected via conductive wire 103, and the emergency stop circuit is a normally closed emergency stop circuit, meaning the circuit is in a closed state. When power is supplied, current flows through the sensing unit 101, the solenoid valve 203, and the normally closed emergency stop circuit. At this point, the solenoid valve 203 is energized, allowing the pressing device to operate normally. During this period, the sensing unit 101 continuously monitors the pressing process, the circuit remains closed, the solenoid valve 203 remains open, and the piston cylinder 201 continues to perform the pressing action.

[0040] When the sensing unit 101 detects an abnormal signal, such as when an operator's hand touches the sensing unit 101, the sensing unit 101 transmits the abnormal signal to the solenoid valve 203 via the conductive wire 103 and triggers the emergency stop circuit. At this time, the normally closed emergency stop circuit will switch from a normal state to an abnormal state after receiving the abnormal signal, and immediately disconnect the circuit, preventing current from passing through the solenoid valve 203, thus acting as a control switch. At this time, the solenoid valve 203 will quickly close the air circuit or cut off other power sources of the equipment due to the loss of power support. Since the solenoid valve 203 is de-energized, the piston cylinder 201 loses power. At this time, the piston cylinder 201 stops moving, the pressing action will also be terminated immediately, and the equipment enters a safe state, which can avoid pinching the operator's hand and prevent accidents.

[0041] More specifically, if Figure 8As shown, this is a circuit diagram of the emergency stop circuit in this embodiment, which controls the power supply through the emergency stop circuit and realizes power supply and power off of the device. Specifically, the circuit uses PMOS (positive channel Metal Oxide Semiconductor, which refers to a transistor that flows and transports current) and NMOS (N-Metal-Oxide-Semiconductor, N-type metal-oxide-semiconductor transistor) and GPIO (general input and output interface) to control the on and off of the solenoid valve 203, thereby controlling the operation of the device. By controlling the level of the GPIO pin, the on and off of the NMOS can be accurately controlled, and the switching state of the PMOS can be indirectly controlled to control the solenoid valve 203. When the PMOS is turned on, the power flows to the VOUT end through the PMOS, the solenoid valve 203 is activated, and the device operates normally; when the PMOS is turned off, the circuit is disconnected, and the device stops working.

[0042] In one embodiment, the sensing part 101 includes a first sensing part 104 and a second sensing part 105, one end of the first sensing part 104 is located inside the pressing block 202, and the other end is located outside the pressing block 202; one end of the second sensing part 105 is connected to the end of the first sensing part 104 located outside the pressing block 202, and the other end faces the pressing platform 3, and the end is located below the pressing block 202; when the second sensing part 105 senses an abnormal signal, the second sensing part 105 transmits the abnormal signal to the first sensing part 104 and the emergency stop circuit in sequence, and the emergency stop circuit cuts off the power supply of the solenoid valve 203 to stop the piston cylinder 201 from working.

[0043] Specifically, such as Figure 4 As shown, one end of the second sensing portion 105 is connected to the end of the first sensing portion 104 located outside the pressing block 202, and the other end is positioned downward, with the end of the second sensing portion 105 located below the pressing block 202. When the operator's hand touches the second sensing portion 105, the second sensing portion 105 transmits an abnormality signal to the first sensing portion 104. The first sensing portion 104 then transmits the abnormality signal to the emergency stop circuit via the conductive wire 103 connected thereto. Upon receiving the abnormality signal, the emergency stop circuit cuts off the power supply to the solenoid valve 203, causing the cylinder drive device 2 to stop operating, thereby stopping the pressing block 202 from moving downward.

[0044] In one embodiment, the safety device 1 further includes a shell 106, which is disposed on one side of the pressing block 202; a placement groove 107 corresponding to the sensing portion 101 is provided in the shell 106, the sensing portion 101 is disposed in the placement groove 107, and the second sensing portion 105 protrudes from the shell 106 at one end facing the pressing platform 3.

[0045] Specifically, such as Figure 2As shown, the housing 106 is provided on the outside of the pressing block 202 and is made of insulating material to prevent the conductive material from affecting the accuracy of the monitoring of the first sensing part 104 or the second sensing part 105. Figure 4 As shown, housing 106 includes a slot 107 corresponding to second sensing portion 105. Second sensing portion 105 is positioned within slot 107 and contacts first sensing portion 104 to ensure transmission of sensed signals. When an operator's hand touches second sensing portion 105, second sensing portion 105 transmits an abnormality signal to first sensing portion 104. Portions of first sensing portion 104 are also located within housing 106 and connected to slot 107.

[0046] In one embodiment, a guide device 6 is further included, which is arranged between the piston cylinder 201 and the pressing platform 3; the guide device 6 includes at least one guide plate 601, which is vertically arranged above the pressing platform 3.

[0047] like Figure 2 As shown, specifically, the guide device 6 includes two guide plates 601, and the guide plates 601 are made of transparent high-strength material, which can facilitate the operator to observe the pressing process and pressing status of the solid-state hard disk in real time. More specifically, the guide plates 601 are installed in the central position of the pressing platform 3, and are placed in a bilaterally symmetrical manner, and are perpendicular to the pressing platform 3, so that the solid-state hard disk can be placed between the guide plates, which can ensure that the solid-state hard disk remains stable and vertical during the up and down movement, and avoid the loosening of the piston cylinder after long-term use, resulting in uneven pressing of the pressing block. At the same time, the guide device 6 plays a role in limiting the pressing block 202, thereby ensuring the integrity of the appearance and internal structure of the solid-state hard disk. Furthermore, the pressing block 202 is located between the guide plates 601, and moves toward the direction of the solid-state hard disk and performs pressing. The guide plates 601 can guide the pressing block 202 and can also play a role in positioning the fixed hard disk.

[0048] In one embodiment, a positioning device is further included. The positioning device is located on the pressing block 202 and is used to fix the solid state hard disk.

[0049] Specifically, before pressing, the SSD's hard drive housing 7 needs to be preliminarily assembled. The hard drive housing 7 comprises an upper housing 701 and a lower housing 702. The pressing platform 3 is provided with a precise positioning device, such as a groove or a clamp, to secure the hard drive housing 7 and prevent it from shifting during the pressing process. In one embodiment, the positioning device is a clamp that clamps the hard drive housing 7 to prevent displacement and facilitate the pressing process.

[0050] More specifically, the upper shell 701 and the lower shell 702 are pre-assembled, and then the pre-assembled hard disk shell 7 is placed in a positioning device and fixed by the positioning device to ensure that no displacement occurs during the pressing process.

[0051] In one embodiment, the pressing platform 3 is further provided with a reset button 301, which is electrically connected to the sensing part 101 and the solenoid valve 203 respectively; when the reset button 301 is pressed, the emergency stop circuit is reset, and the sensing part 101 and the solenoid valve 203 are electrically connected again.

[0052] like Figure 1 As shown, specifically, after the operator eliminates the fault, the emergency stop circuit can be reclosed by manually pressing the reset button 301. At this time, the sensing part 101 re-establishes the electrical connection with the solenoid valve 203, the equipment resumes operation, and continues the pressing action.

[0053] In one embodiment, a starting device 9 is further included. The starting device 9 is electrically connected to the cylinder driving device 2 and is used to drive the cylinder driving device 2 .

[0054] like Figure 5 As shown, specifically, the starting device 9 is a starting button and is electrically connected to the cylinder driving device 2. Pressing the starting device 9 can drive the cylinder driving device 2, drive the piston cylinder 201 to compress the air, and drive the piston rod and the pressing block 202 provided on the piston rod to press.

[0055] In one embodiment, a buffer pad 302 is provided under the pressing platform 3 .

[0056] like Figure 3 Specifically, a cushion 302 is provided beneath the pressing platform 3 to reduce impact during the pressing process and further protect the product. More specifically, the solid-state drive is placed within the guide 6 and positioned above the pressing platform 3. The pressing block 202 moves toward the solid-state drive and presses it. At this point, the cushion 302 cushions the pressing force, thereby protecting the solid-state drive.

[0057] In one embodiment, the guide plate 601 is further provided with a push rod 602, and the push rod 602 is used to push out the fixed hard disk after pressing.

[0058] like Figure 3Specifically, multiple solid-state drives (SSDs) are placed between two guide plates 601. A push rod 602 is located behind the SSDs and is driven by a cylinder or a screw to enable forward and backward movement. After the pressing block 202 presses the SSDs together, it moves away from the SSDs. The push rod 602 then moves forward and pushes the pressed SSDs out from between the guide plates 601, making them easier for the operator to remove.

[0059] In summary, when operating the SSD pressing equipment, the operator first needs to preliminarily assemble the SSD's upper and lower housings 701 and 702, ensuring that the internal circuit boards and other components are properly installed. The operator then carefully checks the alignment of the upper and lower housings 701 and 702 to ensure there are no misalignments or jams. The preassembled hard drive housing 7 is then placed into the positioning device on the pressing platform 3. The positioning device secures the hard drive housing 7 to prevent displacement during the pressing process. After the hard drive housing 7 is placed, the operator checks that the equipment is in its initial state, namely, whether the piston cylinder 201 is positioned upward, and sets the required parameters, such as the piston cylinder 201 pressure, the pressing time, and the die stroke. The operator then presses the start button, causing the piston cylinder 201 to slowly descend, driving the pressing block 202 downward. As the piston cylinder 201 descends, the pressing block 202 gradually applies pressure to the hard drive housing 7. The precise control of pressure by the piston cylinder 201 ensures that the pressure is evenly distributed across the surface of the hard drive housing 7, preventing deformation or damage to the hard drive housing 7 due to excessive localized pressure. In one embodiment, the piston cylinder 201 is pressed for 3 seconds to ensure that the components of the solid state drive are firmly connected. After the pressing time is over, the piston cylinder 201 begins to rise, and the pressing block 202 moves away from the solid state drive. At this time, the solid state drive is pressed.
