[0043] As Figure 1 , Figure 3As shown, the embodiment provides a capping device with protection function, which is used for capping the 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 packaging box. At this time, the packaging box to be pressed is formed. The capping device is used for capping the packaging box to be pressed, so as to package the solid state hard disk. As shown in Figure 1 、 Figure 2 、 Figure 3 As shown, the capping device with protection function of the embodiment mainly comprises a support frame 200, a gas cylinder 300, a pressing block 400 and a safety protection assembly 700. The support frame 200 is arranged along the up-down direction, and the support frame 200 surrounds a containing space 240 with an open port 241 on one side. The open port 241 faces the operator, so as to facilitate the operator to place the packaging box to be pressed into the containing space 240 through the open port 241. The gas cylinder 300 is arranged on the support frame 200, and the pressing block 400 is connected to the gas cylinder 300 and located in the containing space 240. The pressing block 400 is driven by the gas cylinder 300 to move downward to press the packaging box. The range of the containing space 240 can be the coverage range of the pressing block 400 in the horizontal plane. The safety protection assembly 700 is arranged on the support frame 200 and located at the open port 241. The safety protection assembly 700 controls the gas cylinder 300 not to start when the hand enters the containing space 240. When the safety protection assembly 700 detects that the hand enters the containing space 240, even if the switch controlling the gas cylinder 300 is triggered, the gas cylinder 300 will not start, so as to ensure the safety of the operator during use.

[0044] The capping device with protection function of the embodiment comprises the support frame 200, the gas cylinder 300 and the pressing block 400. The support frame 200 surrounds the containing space 240 with the open port 241 on one side, so that the packaging box to be pressed can be placed in the containing space 240 through the open port 241. The pressing block 400 is driven by the gas cylinder 300 to move downward to press the packaging box. Before the gas cylinder 300 starts, the operator puts his hand into the containing space 240. At this time, the safety protection assembly 700 controls the gas cylinder 300 not to start when the hand enters the containing space 240. Therefore, even if the control switch of the gas cylinder 300 is accidentally touched when the hand is put into the containing space 240, the gas cylinder 300 will not start, so as to ensure the safety of the operator during the process of placing and taking out the packaging box.

[0045] As shown in Figure 1 、 Figure 2As shown, the support frame 200 is provided with a cushion 100, which is located at the bottom of the accommodating space 240. The cushion 100 is used to carry and limit the packaging box to be pressed. Usually, the packaging box is provided with a support stopper around the periphery, and the middle area surrounded by the support stopper is concave upward to form a concave cavity, through which the entire packaging box can be placed on the cushion 100 for limiting. The support frame 200 is located on one side of the cushion 100 and is arranged in the up-down direction to play a supporting role. The air cylinder 300 is arranged on the support frame 200 and located above the cushion 100. The pressing block 400 is connected to the air cylinder 300 and moves downward under the driving of the air cylinder 300 to press the packaging box on the cushion 100. When the pressing operation is needed, the air cylinder 300 is started to make the piston rod 310 move downward. The pressing block 400 is connected to the piston rod 310 and also moves downward under the driving of the air cylinder 300, so as to press the box cover downward and connect the box cover to the packaging box. After the extrusion is completed, the piston rod 310 with the pressing block 400 is returned upward by controlling the air cylinder 300 to return, so as to facilitate taking the packaging box which has been pressed from the cushion 100.

[0046] As shown in Figure 1 , Figure 4 , and a buffer layer 500 is arranged on the cushion 100 and located between the packaging box and the cushion 100 to buffer the impact force applied to the packaging box by the pressing block 400. During the downward pressing of the pressing block 400, the impact force applied to the packaging box is large due to the large impact force of the piston rod 310 of the air cylinder 300. The large impact force can be buffered to a certain extent during the extrusion of the pressing block 400, so as to ensure the stability of the pressing force during the pressing process and effectively prevent the box cover and the packaging box from being damaged. The cover pressing device for the hard disk packaging box of the embodiment places the packaging box to be pressed on the cover and on the cushion 100 for limiting through the cushion 100. The air cylinder 300 is started, the pressing block 400 moves downward under the driving of the air cylinder 300 to press the packaging box on the cushion 100, the box cover is pressed tightly on the packaging box, and the cushion 100 is provided with the buffer layer 500, which is located between the packaging box and the cushion 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, the production efficiency is improved, and the unified standard pressing is realized through pneumatic control during batch production, so as to ensure the consistency of the products and realize standardized production.

[0047] As shown in Figure 1 , Figure 4 , Figure 5As shown, further, the cushioning platform 100 of the embodiment specifically comprises: a base 110 for placing on an operating table (table top) to ensure stable placement of the entire capping device; and a square platform 120, which can be square or rectangular and is arranged to match the shape of the recess in the bottom of the packaging box, and can also be arranged in other shapes, such as circular, etc., but the solid state drive is usually square in structure, so it is matched to be square. The square platform 120 is arranged on the base 110 and below the pressing block 400, and the cushioning layer 500 is arranged on the square platform 120, and the packaging box to be pressed is arranged on the square platform 120. By embedding the square platform 120 in the recess in the bottom of the packaging box, the packaging box can be easily arranged on the square platform 120, and the packaging box is not easily displaced or fallen off during the pressing of the box cover.

[0048] As shown in Figure 1 , Figure 4 , Figure 5 As shown, further, the cushioning layer 500 of the embodiment comprises a cushioning air bag 510 arranged on the square platform 120. By using the cushioning air bag 510 for cushioning, a larger impact force can be cushioned during the pressing of the pressing block 400, ensuring the stability of the pressing force during the pressing process, and the box cover and the packaging box can be effectively prevented from being damaged. The cushioning air bag 510 is compressed during the pressing process, thereby playing a cushioning role, and when the air cylinder 300 is retracted, the cushioning air bag 510 can be returned to its original position. During the returning process, the packaging box can be pushed out of the square platform 120, so that the packaging box can be loosened on the square platform 120, making it easier for the worker to remove the packaging box. It is easy to think that the cushioning layer 500 can also use a cushioning pad (such as a rubber layer), a spring pad, etc.

[0049] As shown in Figure 1 , Figure 4 , Figure 5 As shown, further, the cushioning air bag 510 of the embodiment specifically comprises: an air bag skin layer 511, the edges of the air bag skin layer 511 being connected to the square platform 120 and forming an inflation space 520 with the square platform 120. The edges of the air bag skin layer 511 can be fixed to the square platform 120 by adhesion, so that the inflation space 520 is formed between the air bag skin layer 511 and the square platform 120, and the inflation space 520 is filled with a cushioning gas, which inflates the air bag skin layer 511 and plays a cushioning role.

[0050] As shown in Figure 1 , Figure 4 , Figure 5As shown, further, a compression space 121 is provided in the square platform 120 of this embodiment, and the compression space 121 is connected to the inflation space 520 through the vent 122. In the specific structure, a compression space 121 is provided inside the square platform 120. 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 smoother. When the box cover is pressed tightly 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.

[0051] 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 arranged in the vertical direction on the surface of the square platform 120. The provision of multiple filling 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 filling space 520 is immediately compressed. Since the vent holes 122 can only allow part of the gas to enter the compression space 121 in a short period of time, during the impact, the compressed buffer gas in the filling space 520 squeezes the packaging box, thereby forming an extrusion force on the packaging box from below. In this way, under the combined action of the squeezing force of the pressing block 400 above and the squeezing force of the compressed buffer gas below, the box lid can be squeezed onto the protective box first. Subsequently, as the buffer gas in the filling space 520 is squeezed into the compression space 121 through the vent holes 122, the buffer airbag 510 also slowly shrinks. Finally, the packaging box is mainly supported by the square platform 120, so that the box lid is gradually compressed. In this way, a better buffering effect is achieved during the squeezing process.

[0052] like Figure 4 、 Figure 5 、 Figure 6As shown, further, the surface of the square platform 120 of the embodiment is provided with a plurality of first hole groups 130 and second hole groups 140, and each of the first hole groups 130 and the second hole groups 140 includes a plurality of air holes 122. The air holes 122 of the embodiment are provided at different positions and have different sizes, so that the air holes 122 are divided into two groups, i.e., the first hole groups 130 and the second hole groups 140. The first hole groups 130 are distributed at the four corners of the surface of the square platform 120, and the second hole groups 140 are distributed at the central position of the surface of the square platform 120. By providing the air holes 122 at different positions of the surface of the square platform 120, the pressing force applied to different positions of the bottom surface of the packaging box is different when the pressing block 400 presses the buffer air bag 510, so that, for the positions corresponding to the first hole groups 130 and the second hole groups 140, the buffer gas can flow quickly during the pressing process, so that the buffer effect on the impact force at these positions is relatively small, so that the impact force of the pressing block 400 is applied to these regions, so that the box cover can be quickly pressed at the middle position and the four corner positions, so as to facilitate the pressing of the box cover on the packaging box.

[0053] As shown in Figure 4 , Figure 5 , Figure 6 As shown, further, the hole diameter of the air holes 122 in the first hole groups 130 of the embodiment is larger than the hole diameter of the air holes 122 in the second hole groups 140. By providing different hole diameters, the packaging box is more easily ejected during the restoration process of the buffer air bag 510. In the specific process, after the box cover is pressed on the packaging box, the cylinder 300 is returned to move the pressing block 400 upward, so that the compressed gas in the compression space 121 can enter the inflation space 520 through the air holes 122, and the air holes 122 in the first hole groups 130 are relatively large, so that the buffer gas in the compression space 121 quickly enters the buffer air bag 510 through the air holes 122 in the first hole groups 130, and the air inlet speed at this position is greater than the air inlet speed at the position of the second hole groups 140 in the middle, so that the recovery speed of the buffer air bag 510 at the four corners of the position of the first hole groups 130 is fast, and thus the pushing force applied by the buffer air bag 510 at the four corner positions of the bottom of the packaging box is relatively large, so that the four corner positions of the bottom of the packaging box can be quickly ejected. Generally, after being pressed, the four corner positions of the bottom of the packaging box are tightly fitted with the concave cavity and the square platform 120, so that the four corner positions of the bottom of the packaging box are first quickly ejected, and then the air holes 122 at the position of the second hole groups 140 in the middle slowly ventilate, so as to eject the packaging box as a whole, which is more beneficial to eject the entire packaging box to make the concave cavity separate from the square platform 120.

[0054] As shown in Figure 1 , Figure 4 , Figure 7As shown, further, the support frame 200 of the embodiment specifically comprises: a support column 210, a top platform 220, and a surrounding plate 230. The support column 210 is arranged on the base 110 and extends in the up-down direction by a predetermined length, the top platform 220 is fixedly arranged at the top end of the support column 210, the air cylinder 300 is arranged on the top platform 220, and the piston rod 310 of the air cylinder 300 penetrates through the top platform 220, and the pressing block 400 is connected to the piston rod 310 and located below the top platform 220. The surrounding plate 230 is connected to the top platform 220 and the base 110 at the upper and lower ends thereof respectively, and encloses a containing space 240, the side of the containing space 240 away from the support column 210 forms an open mouth 241, and the square platform 120 is located in the containing space 240, and the packaging box can be placed on the square platform 120 through the open mouth 241 of the containing space 240. The safety protection assembly 700 is specifically arranged on the surrounding plate 230 and located at the left and right sides of the open mouth 241, and safety protection is performed at the open mouth 241.

[0055] The safety protection assembly 700 in the embodiment can be in various forms, and specifically as follows:

[0056] As shown in Figure 1 , Figure 2 , in the first structure, the safety protection assembly 700 specifically comprises: a travel switch 710 and a pressure receiving part 720. The travel switch 710 is arranged at the open mouth 241, and in a specific structure, for example, two travel switches 710 can be arranged, and the two travel switches 710 are arranged at the left and right sides of the open mouth 241 respectively. The pressure receiving part 720 is movably arranged at the open mouth 241, and the pressure receiving part 720 is actuated to touch the travel switch 710 by being squeezed by a hand, and the travel switch 710 is controlled to not start the air cylinder 300. When the hand of the operator wants to take or put down the packaging box in the containing space 240, the hand of the operator will pass through the open mouth 241, so as to touch the pressure receiving part 720, and when the pressure receiving part 720 is squeezed by the hand of the operator, the pressure receiving part 720 is moved and squeezes the travel switch 710, so that the travel switch 710 generates a control signal and controls the air cylinder 300 not to start.

[0057] As shown in Figure 1 , Figure 2 , the pressure receiving part 720 in the embodiment specifically comprises: two movable arms 721 at the two sides, two elastic members 723 at the two sides, and a pressure receiving rod 722. The two movable arms 721 are rotatably arranged at the two sides of the open mouth 241 and can abut against the travel switch 710, the two elastic members 723 are arranged at the two 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 fixedly arranged on the two movable arms 721 respectively. In the process of placing or taking out the packaging box by the hand, the pressure receiving rod 722 is actuated to touch the travel switch 710 by the downward pressing of the arm, so as to control the air cylinder 300 not to start.

[0058] As shown in Figure 1 , Figure 2 , in the specific structure, the height of the cushion table 100 is less than the height of the pressure bar 722, so that the hand downwardly places and takes out the packaging box, thereby extruding the pressure bar 722 downwardly, the movable arm 721 at one end of which is hinged to the surrounding baffle 230 is extruded by the downwardly movable arm 721 to extrude the travel switch 710, thereby causing the travel switch 710 to generate a control signal. When the hand moves out of the open port 241, the pressure bar 722 is not extruded and can be moved upwardly to restore the original position under the action of the elastic member 723, so that the travel switch 710 is not extruded and is returned to the original position, so that the air cylinder 300 can be started under the control of the switch to realize the normal pressing function.

[0059] As shown in Figure 3 , in the second structure, the safety protection assembly 700 includes a photoelectric sensor 730, and the photoelectric sensor 730 is arranged on the surrounding baffle 230 and located on the left and right sides of the open port 241. In the process of placing the packaging box by the hand, the hand is inserted into the open port 241, thereby being sensed by the photoelectric sensor 730 to generate a control signal. When the hand moves out of the open port 241, the photoelectric sensor 730 cannot sense the hand, so that the air cylinder 300 can be started under the control of the switch to realize the normal pressing function.

[0060] As shown in Figure 1 , Figure 8 , further, the pressing device of the embodiment further includes a foot switch 600 and an electromagnetic valve 610. The foot switch 600 is connected to the electromagnetic valve 610, the safety protection assembly 700 is connected to the electromagnetic valve 610, and the electromagnetic valve 610 is connected to the air cylinder 300. The electromagnetic valve 610 is used to control the air cylinder 300 to press the pressing block 400 downwardly or to retract the pressing block 400 upwardly. When the hand is not in the containing space 240 and the safety protection assembly 700 is not triggered, the foot switch 600 is connected to the electromagnetic valve 610, the air supply of the air cylinder 300 is controlled by the electromagnetic valve 610, and the piston rod 310 of the air cylinder 300 can be extended and retracted to realize the pressing function. When the hand is in the containing space 240 and the safety protection assembly 700 is triggered, even if the foot switch 600 sends a control signal to the electromagnetic valve 610, the electromagnetic valve 610 does not supply air to the air cylinder 300, thereby playing a safety protection role. The foot switch 600 can be controlled by the foot, so that the hands of the worker can place the packaging box, and the foot can be controlled to improve the operability of the device.

[0061] AsFigure 1 、 Figure 8 As shown in FIG. 3, further, the cylinder 300 in the embodiment is connected to the pressing block 400 through the adjusting rod 320, and the lower pressing limit height of the pressing block 400 is adjusted through the adjusting rod 320. The position of the pressing block 400 connected to the piston rod 310 of the cylinder 300 is adjusted through the adjusting rod 320, so as to adjust the lower pressing height of the pressing block 400, and thus adjust the tightness degree of the box cover pressed on the packaging box.

[0062] In summary, the application provides a pressing device with a protection function, which is provided with a support frame, a cylinder and a pressing block. The support frame is surrounded to form a containing space with an open port, so that the packaging box to be pressed can be placed in the containing space from the open port, and then the pressing block is driven to move downward by the cylinder to press the packaging box. Before the cylinder is started, the operator puts his hand into the containing space, and at this time, the safety protection assembly controls the cylinder not to start when the hand enters the containing space. Therefore, even if the control switch of the cylinder is mistakenly touched when the hand is put into the containing space, the cylinder will not start, so as to ensure the safety of the operator in the process of placing and taking out the packaging box.

[0063] The above only describes the preferred embodiments of the application and is not used to limit the application. Any modification, equivalent replacement and improvement made within the spirit and principle of the application should be included in the protection scope of the application.
