[0002] Solid State Drive (SSD) is widely used in various fields due to its powerful random read and write capabilities. SSD can be installed on a host as the host's storage medium. The host sends data to the SSD so that the SSD writes the sent data into the SSD for storage. When the SSD is produced, it needs to be boxed.

[0003] In the existing packaging process, an extruder can be used to press the box cover onto the hard disk box body, so that the hard disk box is closed. The existing pressing process is driven by a cylinder. After the operator places the packaging box, the cylinder is started, and then the cylinder applies pressure to press the box cover onto the protective box. However, there is no protective device on the extruder. It is possible that the operator's hand is still placing the packaging box, and the cylinder is started due to misoperation, which may press the operator's fingers and cause an accident. Therefore, the safety performance of the existing extruder is not high.

[0022] like Figure 1 , Figure 3 As shown, this embodiment provides a protective cover device for covering a hard disk packaging box. The solid state hard disk is placed in the packaging box in advance, and then the box cover is turned over to cover the open opening of the packaging box, and then a packaging box to be pressed is formed. The packaging box to be pressed is pressed by the cover device, so that the solid state hard disk is packaged. Figure 1 , Figure 2 , Figure 3As shown, the capping device with protective function of this embodiment mainly includes: a support frame 200, a cylinder 300, a pressing block 400 and a safety protection component 700. The support frame 200 is arranged in the up-down direction, and the support frame 200 is surrounded by a receiving space 240 with an open mouth 241 on one side, and the open mouth 241 faces the operator, so that it is convenient for the operator to place the packaging box to be pressed into the receiving space 240 through the open mouth 241. The cylinder 300 is arranged on the support frame 200, and the pressing block 400 is connected to the cylinder 300 and is located in the receiving space 240. It moves downward by the drive of the cylinder 300 to press the packaging box. The range of the receiving space 240 can be the coverage range of the pressing block 400 in the horizontal plane. The safety protection component 700 is arranged on the support frame 200 and is located at the open mouth 241. The safety protection component 700 controls the cylinder 300 not to start when a person enters the receiving space 240. When the safety protection component 700 detects that a human hand enters the accommodating space 240, even if the switch of the control cylinder 300 is triggered, the cylinder 300 will not be ventilated and started, thereby ensuring the safety of the operator during use.

[0023] The capping device with protective function of this embodiment is provided by setting a support frame 200, a cylinder 300 and a pressing block 400. The support frame 200 is surrounded by a receiving space 240 with an open mouth 241 on one side, so that the packaging box to be pressed can be placed in the receiving space 240 from the open mouth 241, and then the pressing block 400 is moved downward by the drive of the cylinder 300 to press the packaging box. Before the cylinder 300 is started, the operator reaches into the receiving space 240 by hand. At this time, the safety protection component 700 controls the cylinder 300 not to start when the hand enters the receiving space 240. Then, when the hand reaches into the receiving space 240, even if the control switch of the cylinder 300 is accidentally touched, the cylinder 300 will not start, thereby ensuring the safety of the operator in the process of placing and taking out the packaging box.

[0024] like Figure 1 , Figure 2As shown, a pad 100 is provided on the support frame 200, and the pad 100 is located at the bottom of the accommodating space 240. The pad 100 is used to carry and limit the packaging box to be pressed together. Usually, supporting ribs are provided around the periphery of the packaging box, and the middle area surrounded by the supporting ribs is concave upward to form a cavity, through which the entire packaging box can be placed on the pad 100 for limiting. The support frame 200 is located on one side of the pad 100, and the support frame 200 is arranged in the up and down direction to play a supporting role. The cylinder 300 is provided on the support frame 200 and is located above the pad 100. The pressing block 400 is connected to the cylinder 300 and moves downward by the drive of the cylinder 300 to press the packaging box on the pad 100. When the pressing operation is required, the air cylinder 300 is activated to move the piston rod 310 downward, and the pressing block 400 is connected to the piston rod 310 and also moves downward under the drive of the air cylinder 300, thereby pressing the box cover below, so that the box cover is pressed and connected to the packaging box. After the pressing is completed, the air cylinder 300 is controlled to return to its original position, so that the piston rod 310 and the pressing block 400 return upward, so that the pressed packaging box can be easily removed from the pad 100.

[0025] like Figure 1 , Figure 4 As shown, a buffer layer 500 is provided on the pad 100, and the buffer layer 500 is located between the packaging box and the pad 100 to buffer the impact force applied to the packaging box by the pressing block 400. During the downward pressing process of the pressing block 400, since the impact force of the piston rod 310 of the cylinder 300 is relatively large, the impact force applied to the packaging box is very large. The buffer layer 500 is used for buffering, and the large impact force can be buffered to a certain extent during the squeezing process of the pressing block 400, ensuring the stability of the force applied during the pressing process, and effectively preventing the box cover and the packaging box from being damaged. The cover pressing device for the hard disk packaging box of this embodiment, by providing the pad 100, closes the cover of the packaging box to be pressed, and places it on the pad 100, and limits the position by the pad 100. By starting the air cylinder 300, the pressing block 400 moves downward under the drive of the air cylinder 300 to press the packaging box on the cushion platform 100, so that the box cover is pressed tightly on the packaging box, and a buffer layer 500 is provided on the cushion platform 100, and the buffer layer 500 is located between the packaging box and the cushion platform 100 to buffer the impact force applied to the packaging box by the pressing block 400. Therefore, the box cover can be pressed tightly on the packaging box through pneumatic control, which improves production efficiency, and in the process of mass production, unified standard pressing is achieved through pneumatic control, ensuring good consistency of factory products and realizing standardized production.

[0026] like Figure 1 , Figure 4 , Figure 5As shown, further, the pad 100 of this embodiment specifically includes: a base 110 and a square table 120, and the base 110 is used to be placed on the operating table (desktop) to ensure the stable placement of the entire cover pressing device. The square table 120 can be a square or a rectangle, and it is matched and set according to the shape of the concave cavity at the bottom of the packaging box. It can also be set to other shapes, such as a circle, etc., but the solid-state hard disk is usually a square structure, so it is matched and set to a square. The square table 120 is set on the base 110 and is located below the pressing block 400. The buffer layer 500 is set on the square table 120, and the packaging box to be pressed is used to be sleeved on the square table 120. The square table 120 is embedded in the concave cavity at the bottom of the packaging box, so that the packaging box is conveniently sleeved on the square table 120. During the pressing process of the box cover, the packaging box is not easy to shift and fall off.

[0027] like Figure 1 , Figure 4 , Figure 5 As shown, further, the buffer layer 500 of this embodiment includes a buffer airbag 510, and the buffer airbag 510 is arranged on the square table 120. By buffering with the buffer airbag 510, a certain buffering can be performed on the larger impact force during the extrusion of the pressing block 400, ensuring the stability of the force applied during the pressing process, and effectively preventing the box cover and the packaging box from being damaged. The buffer airbag 510 is compressed during the pressure process, thereby playing a buffering role, and when the cylinder 300 retracts, the buffer airbag 510 can return to its original position, and the packaging box can be pushed out of the square table 120 during the return process, so that the packaging box can be loosened on the square table 120, so that the staff can remove the packaging box more easily. It is easy to think that the buffer layer 500 can also use a buffer pad (such as a rubber layer), a spring pad, etc.

[0028] like Figure 1 , Figure 4 , Figure 5 As shown, further, the cushioning airbag 510 of this embodiment specifically includes: an airbag skin layer 511, the edge of the airbag skin layer 511 is connected to the square platform 120, and the airbag skin layer 511 and the square platform 120 form an inflatable space 520. The edge of the airbag skin layer 511 can be fixed to the square platform 120 by bonding, so that an inflatable space 520 is formed between the airbag skin layer 511 and the square platform 120, and the inflatable space 520 is filled with cushioning gas, and the airbag skin layer 511 is filled with the cushioning gas to play a cushioning role.

[0029] like Figure 1 , Figure 4 , Figure 5As shown, further, a compression space 121 is opened in the square platform 120 of this embodiment, and the compression space 121 is connected with the inflation space 520 through the vent 122. In the specific structure, a compression space 121 is opened inside the square platform 120, and the compression space 121 is a cavity that can store buffer gas, and the compression space 121 is located below the inflation space 520. The vent 122 is arranged in the up and down directions and connects the inflation space 520 and the compression space 121. In the initial state, the buffer gas fills the entire inflation space 520 and the compression space 121, so that the buffer airbag 510 is propped up as a whole; when the pressing block 400 is pressed downward, the buffer airbag 510 is compressed, and the buffer gas is compressed into the compression space 121 as a whole. Since the compression space 121 can increase the total amount of buffer gas, the buffering during the extrusion process of the pressing block 400 will be more stable. When the box cover is pressed onto the packaging box, the cylinder 300 returns to its original position and moves upward with the pressing block 400, so that the compressed gas in the compression space 121 can enter the inflation space 520 through the vent 122, thereby propping up the buffer airbag 510, so that the buffer airbag 510 can further prop up the packaging box, so that the packaging box can be loosened on the square table 120.

[0030] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, further, in this embodiment, a plurality of vent holes 122 are provided, and the plurality of vent holes 122 are provided on the surface of the square platform 120 in the vertical direction. The form of providing a plurality of inflatable holes can slow down the compression process of the buffer gas during the compression process, that is, when the pressing block 400 squeezes the buffer airbag 510, the buffer gas in the inflatable space 520 is compressed immediately. Since the vent holes 122 can only allow part of the gas to enter the compression space 121 in a short time, the compressed buffer gas in the inflatable space 520 squeezes the packaging box during the impact, thereby forming an extrusion force on the packaging box from below. In this way, under the combined effect of the squeezing force of the pressing block 400 above and the squeezing force of the compressed buffer gas below, the box cover can be squeezed onto the protective box first, and then the buffer gas in the inflatable space 520 is squeezed into the compression space 121 through the vent holes 122, so that the buffer airbag 510 also slowly shrinks, and finally the packaging box is mainly supported by the square platform 120, so that the box cover is gradually compressed. In this way, a better buffering effect is achieved during the squeezing process.

[0031] like Figure 4 , Figure 5 , Figure 6As shown, further, the surface of the square platform 120 of this embodiment is provided with a plurality of first hole groups 130 and a second hole group 140, and the first hole group 130 and the second hole group 140 both include a plurality of vents 122. The positions and sizes of the vents 122 of this embodiment are not the same, so the plurality of vents 122 are divided into two groups, namely the first hole group 130 and the second hole group 140. The first hole group 130 is distributed at the four corners of the surface of the square platform 120, and the second hole group 140 is distributed at the center of the surface of the square platform 120. By arranging air holes 122 at different positions on the surface of the square platform 120, when the pressing block 400 squeezes the buffer airbag 510, the squeezing forces applied to different positions of the bottom surface of the packaging box are different. In this way, for the positions corresponding to the first hole group 130 and the second hole group 140, the buffer gas can flow quickly during the squeezing process, so that the buffering effect of the impact force here is relatively small, so that the impact force of the pressing block 400 is applied to these areas with a relatively large force, so that the box cover can be quickly pressed at the middle position and the four corner positions, thereby facilitating the box cover to be pressed tightly onto the packaging box.

[0032] like Figure 4 , Figure 5 , Figure 6 As shown, further, the aperture of the vent holes 122 in the first hole group 130 of the present embodiment is larger than the aperture of the vent holes 122 in the second hole group 140. By setting different apertures, the packaging box is easier to be ejected during the restoration process of the buffer airbag 510. In the specific process, after the box cover is pressed tightly on the packaging box, the cylinder 300 returns to its original position and moves upward with the pressing block 400, so that the compressed gas in the compression space 121 can enter the inflation space 520 through the vent holes 122, and the vent holes 122 in the first hole group 130 are relatively large, so that the buffer gas in the compression space 121 can quickly enter the buffer airbag 510 through the vent holes 122 in the first hole group 130, and the air intake speed there is greater than the air intake speed at the location of the second hole group 140 in the middle. At this time, at the location of the first hole group 130, the air intake speed at the four The cushioning airbags 510 at the corners have a fast recovery speed, so the thrust exerted by the cushioning airbags 510 at the four corners of the bottom of the packaging box is relatively large, so that the four corners of the bottom of the packaging box can be quickly pushed up. Usually, after being squeezed, the four corners of the bottom of the packaging box are tightly matched with the square platform 120 through the concave cavity. Therefore, the four corners of the bottom of the packaging box are quickly pushed up first, and then the ventilation holes 122 at the position of the second hole group 140 in the middle are slowly ventilated, so that the packaging box is pushed up as a whole, which is more conducive to ejecting the entire packaging box and separating the concave cavity from the square platform 120.

[0033] like Figure 1 , Figure 4 , Figure 7As shown, further, the support frame 200 of this embodiment specifically includes: a support column 210, a top platform 220 and a baffle plate 230. The support column 210 is arranged on the base 110 and extends a predetermined length in the up-down direction. The top platform 220 is fixedly arranged at the top of the support column 210. The cylinder 300 is arranged on the top platform 220, and the piston rod 310 of the cylinder 300 passes through the top platform 220. The pressing block 400 is connected to the piston rod 310 and is located below the top platform 220. The upper and lower ends of the baffle plate 230 are respectively connected to the top platform 220 and the base 110, and enclose a receiving space 240. The receiving space 240 forms an open mouth 241 on the side away from the support column 210. The square platform 120 is located in the receiving space 240, and the packaging box can be placed on the square platform 120 through the open mouth 241 of the receiving space 240. The safety protection assembly 700 is specifically disposed on the enclosure plate 230 and is located on the left and right sides of the opening 241 to provide safety protection at the opening 241 .

[0034] The security protection component 700 in this embodiment can be in various forms, as follows: like Figure 1 , Figure 2 As shown, in the first structure, the safety protection component 700 specifically includes: a travel switch 710 and a pressure-receiving part 720. The travel switch 710 is arranged at the open mouth 241. In the specific structure, for example, two travel switches 710 can be arranged, and the two travel switches 710 are arranged on the left and right sides of the open mouth 241 respectively. The pressure-receiving part 720 is movably arranged at the open mouth 241. The pressure-receiving part 720 is pressed by a human hand to trigger the travel switch 710, and the cylinder 300 is controlled not to start through the travel switch 710. When the operator's hand wants to take or put down the packaging box in the accommodating space 240, the operator's hand will pass through the open mouth 241, so that the pressure-receiving part 720 will be touched. When the pressure-receiving part 720 is pressed by the operator's hand, it moves and presses the travel switch 710, so that the travel switch 710 generates a control signal and controls the cylinder 300 not to start.

[0035] like Figure 1 , Figure 2 As shown, the pressure receiving part 720 in this embodiment specifically includes: movable arms 721 on both sides, elastic members 723 on both sides, and a pressure receiving rod 722. The movable arms 721 on both sides are rotatably arranged on both sides of the open mouth 241 and can abut against the travel switch 710; the elastic members 723 on both sides are respectively arranged on both sides of the open mouth 241 and correspondingly connected to the movable arms 721, and the two ends of the pressure receiving rod 722 are respectively fixed on the movable arms 721 on both sides. In the process of placing or taking out the packaging box by hand, the pressure receiving rod 722 triggers the travel switch 710 through the downward pressure of the arm and controls the cylinder 300 not to start.

[0036] like Figure 1 , Figure 2 As shown, in the specific structure, the height of the pad 100 is smaller than the height of the pressure rod 722, so that when the human hand places or takes out the packaging box, the human hand takes it downward, thereby pressing the pressure rod 722 downward, so that the pressure rod 722 drives the movable arm 721 to move downward, and one end of the movable arm 721 is hinged on the baffle plate 230. The movable arm 721 that moves downward squeezes the travel switch 710, so that the travel switch 710 generates a control signal. When the human hand moves out of the open mouth 241, the pressure rod 722 is not squeezed and can move upward to return to its original position under the action of the elastic member 723. In this way, the travel switch 710 is not squeezed and returns to its original position, so that the cylinder 300 can be ventilated and started under the control of the switch to achieve a normal pressing function.

[0037] like Figure 3 As shown, in the second structure, the safety protection component 700 includes: photoelectric sensors 730, which are respectively arranged on both sides of the open mouth 241. When a person places a packaging box by hand, the photoelectric sensor 730 controls the cylinder 300 not to start by sensing the position of the arm at the open mouth 241. In the specific structure, the photoelectric sensor 730 is arranged on the baffle plate 230 and is located on the left and right sides of the open mouth 241. When a person places a packaging box by hand or takes out a packaging box, the person's hand reaches into the open mouth 241, and is sensed by the photoelectric sensor 730 to generate a control signal. When the person's hand moves out of the open mouth 241, the photoelectric sensor 730 cannot sense the person's hand, so that the cylinder 300 can be ventilated and started under the control of the switch to achieve a normal pressing function.

[0038] like Figure 1 , Figure 8 As shown, further, the capping device of this embodiment also includes: a foot switch 600 and a solenoid valve 610. The foot switch 600 is connected to the solenoid valve 610, the safety protection component 700 is connected to the solenoid valve 610, and the solenoid valve 610 is connected to the cylinder 300. The solenoid valve 610 is used to control the cylinder 300 so that the pressing block 400 is pressed down or retracted upward. When the human hand is not in the accommodating space 240 and the safety protection component 700 is not triggered, the solenoid valve 610 is connected to the foot switch 600, and the air supply of the cylinder 300 is controlled by the solenoid valve 610, so that the piston rod 310 of the cylinder 300 can be extended and retracted, and the pressing function is played. When the human hand is in the accommodating space 240 and the safety protection component 700 is triggered, even if the foot switch 600 sends a control signal to the solenoid valve 610, the solenoid valve 610 does not supply air to the cylinder 300, thereby playing a role of safety protection. The foot switch 600 can be controlled by foot, so that the worker can place the packaging box with both hands and control it with the foot, thereby improving the operability of the device.

[0039] like Figure 1 , Figure 8 As shown, further, the air cylinder 300 in this embodiment is connected to the pressing block 400 through the adjusting rod 320, and the pressing limit height of the pressing block 400 is adjusted by the adjusting rod 320.
