Description

Compression device

[0001] The present disclosure relates to a compression device having a buffer member for reducing the rotational speed of the compression device.

[0002] A compression device is a device that applies a predetermined force to a compression target mounted on a jig. The compression device may include a first plate on which the compression target is mounted, and a second plate that is rotatably connected to the first plate and presses the compression target mounted on the first plate. The compression target is pressed and compressed by the second plate that rotates to face the first plate.

[0003] When the above compression target is a portable electronic device, the compression device may be used to compress components of the portable electronic device that are temporarily assembled so that the components constituting the portable electronic device (e.g., a housing forming an exterior and a display, etc.) are coupled to each other, or to attach a film having adhesive strength and insulating and / or waterproofing functions to be placed inside / outside the portable electronic device.

[0004] The compression device may further include a buffer member that reduces the rotational speed of the second plate, which increases as it approaches the first plate during the operation of the compression device, in order to prevent damage to the compression object and injury to the operator. The buffer member may collide with the second plate at a point where the first and second plates form a predetermined angle during the operation of the compression device, thereby reducing the rotational speed of the second plate. However, when the buffer member collides with the second plate, fatigue due to the collision may accumulate in a specific vicinity of the buffer member, resulting in damage to the buffer member over the long-term use of the compression device.

[0005] Various embodiments of the present disclosure can provide a compression device having a rotating member provided on a second plate that disperses an impact force applied to a buffer member during operation of the compression device.

[0006] A compression device according to one embodiment of the present disclosure may include a first plate, a second plate rotatably connected to the first plate via a hinge device, a buffer member disposed on an upper surface of the first plate, and a first rotational member positioned to contact the buffer member when the second plate rotates in a direction facing the first plate, and rotating or rolling along a surface of the buffer member by the contact.

[0007] Various embodiments of the present disclosure can improve the durability of the buffer member by dispersing the impact force applied to the buffer member by rotating the buffer member along the surface of the buffer member when the buffer member provided on the first plate and the rotating member provided on the second plate collide during the operation of the compression device.

[0008] The effects that can be achieved by the exemplary embodiments of the present disclosure can be clearly derived and understood by those skilled in the art to which the exemplary embodiments of the present disclosure pertain, from the following description. In other words, unintended effects resulting from the implementation of the exemplary embodiments of the present disclosure can also be derived by those skilled in the art from the exemplary embodiments of the present disclosure.

[0032] The operating principle and embodiments of the present invention will be described with reference to the attached drawings below.

[0033] FIG. 1 is a perspective view showing an open state of a compression device according to one embodiment of the present disclosure.

[0034] Fig. 2 is a perspective view showing a rotational state of a compression device according to one embodiment of the present disclosure.

[0035] FIG. 3 is a perspective view showing a closed state of a compression device according to one embodiment of the present disclosure.

[0036] Referring to FIGS. 1 to 3, a compression device (100) according to an example may include a base plate (110), a first plate (120), a second plate (130), a hinge device (140), a buffer member (150), a first rotation member (160), and an up-down driving unit (170).

[0037] According to an example, the base plate (110) may be arranged to support the first plate (120) and the second plate (130).

[0038] In one example, the base plate (110) may have a plate shape. For example, the base plate (110) may have a rectangular shape, but the present disclosure is not limited thereto. In one example, the base plate (110) may be positioned on the lower side (e.g., in the -z-axis direction) of the first plate (120).

[0039] According to one example, the first plate (120) may be arranged to secure a pressing object (e.g., a portable electronic device (not shown)) to the upper surface (e.g., the surface facing the +z axis).

[0040] According to one example, a mounting portion (121) that is sunken to a predetermined depth downward (e.g., in the -z-axis direction) may be formed on the upper surface of the first plate (120). The object to be compressed may be fixed on the first plate (120) through the mounting portion (121). In one example, the first plate (120) may have a plate shape. For example, the first plate (120) may have a rectangular shape, but the present disclosure is not limited thereto.

[0041] According to one example, a first fixing member (122) may be arranged at a position close to the upper surface shear of the first plate (120). In one example, the first fixing member (122) may be composed of a magnetic material such as a magnet, and may stably maintain the closed state of the compression device (100) by interaction (e.g., magnetic action) with the second fixing member (132) described below. The closed state may mean a state in which the first plate (120) and the second plate (130) are arranged in parallel while facing each other (see FIG. 3).

[0042] In one example, the second plate (130) may be rotatably connected to the first plate (120) via a hinge device (140). In one example, the second plate (130) may be positioned facing the upper side (e.g., in the +z-axis direction) of the first plate (120) in the closed state of the compression device (100). The first plate (120) may be referred to as a lower plate, and the second plate (130) may be referred to as an upper plate.

[0043] According to one example, a pressing portion (131) may be provided on the lower surface (130a) of the second plate (130) (e.g., the surface facing the first plate (120) in the closed state of the pressing device (100)) to contact (or pressurize) the pressing object mounted on the first plate (120) in the closed state of the pressing device (100). In one example, the pressing portion (131) may be arranged to face the mounting portion (121) of the first plate (120) in the closed state of the pressing device (100). In one example, at least a portion of the pressing portion (131) may have a shape corresponding to the mounting portion (121). In one example, the pressing portion (131) may be made of a urethane material, but the present disclosure is not limited thereto.

[0044] According to one example, a second fixing member (132) may be positioned close to the rear shear of the second plate (130). In one example, the second fixing member (132) may be formed of a magnetic material such as a magnet, and may stably maintain the closed state of the compression device (100) by interaction (e.g., magnetic action) with the first fixing member (122).

[0045] According to one example, a handle (133) that can be gripped by a worker may be provided on the upper surface (130b) of the second plate (130). In one example, the handle (133) may be positioned near the front end of the upper surface of the second plate (130), but the present disclosure is not limited thereto.

[0046] In one example, the hinge device (140) may be provided to support the rotational movement of the second plate (130) with respect to the first plate (120). In one example, the hinge devices (140) may be provided in pairs, and each hinge device (140) may be connected to the first plate (120) and the second plate (130) respectively at the rear end of the upper surface of the first plate (120).

[0047] According to one example, the buffer member (150) may be provided to reduce the rotational speed of the second plate (130) by contacting (or colliding) with the first rotation member (160) provided on the second plate (130) during the process of transitioning from the open state to the closed state of the compression device (100) according to the rotation of the second plate (130). In one example, the buffer member (150) may be arranged at a position close to the rear end of the upper surface of the first plate (120). In one example, the buffer member (150) may be arranged at a position adjacent to the hinge device (140). In one example, the buffer member (150) may include a hydraulic buffer structure (e.g., a hydraulic damper) or a gas buffer structure (e.g., a gas damper). The buffer member (150) may be referred to as a shock absorber or a damper. Hereinafter, the structure of the buffer member (150) will be described with reference to FIGS. 5 and 6.

[0048] According to one example, the first rotating member (160) may be configured to contact (or collide) with the buffer member (150) provided on the first plate (130) during the process of transitioning from the open state to the closed state of the compression device (100) according to the rotation of the second plate (130), and to disperse the impact force applied to the buffer member (150).

[0049] According to one example, the first rotating member (160) can rotate or roll when colliding with the buffer member (150) and disperse the impact force applied to the buffer member (150). In one example, the first rotating member (160) can be configured to be capable of rotating or rolling. For example, the first rotating member (160) can include a roller or a ball caster, but the present disclosure is not limited thereto. Hereinafter, the structure of the first rotating member (160) will be described with reference to FIGS. 5 and 6.

[0050] In one example, the first rotating member (160) may be positioned close to the rear end of the bottom surface (130a) of the second plate (130). In one example, the first rotating member (160) may be positioned so that at least a portion of the first rotating member (160) is in contact with the buffer member (150) when the compression device (100) is in a closed state.

[0051] In one example, the up-and-down driving unit (170) may be provided to adjust the height of the compression device (100). In one example, the up-and-down driving unit (170) may be extended / shortened in the up-and-down direction (e.g., ±z-axis direction) by an operator's operation to change the height of the compression device (100).

[0052] In one example, the upper and lower driving units (170) may be arranged between the base plate (110) and the first plate (120). In one example, the upper and lower driving units (170) may be connected to the base plate (110) and the first plate (120), respectively. In one example, at least one upper and lower driving unit (170) may be provided. For example, when the upper and lower driving units (170) are arranged with four upper and lower driving units, each upper and lower driving unit may be arranged at each corner of the base plate (110).

[0053] FIG. 4 is a drawing for explaining the operation of a compression device according to one embodiment of the present disclosure.

[0054] Fig. 4 is a drawing showing a state in which a buffer member (150) and a first rotating member (160) come into contact (or collide) while the second plate (130) rotates and the compression device (100) changes from an open state to a closed state. In Fig. 4, the position of the first plate (130) in the open state of the compression device (100) is shown by a dotted line.

[0055] Referring to FIG. 4, according to an example, the first plate (130) may be positioned at a predetermined angle (e.g., an obtuse angle) with respect to the first plate (120) in the open state of the compression device (100). When the operator grips the handle (133) of the second plate (130) and applies an external force to the second plate (130) in a counterclockwise direction, the second plate (130) rotates counterclockwise to approach the first plate (120). The buffer member (150) and the first rotation member (160) come into contact with each other (or collide) at a point where the second plate (130) and the first plate (120) form a predetermined angle (θ) while the second plate (130) rotates counterclockwise. At this time, the buffer member (150) performs a buffering operation to reduce the rotational speed of the second plate (130), and the first rotating member (160) performs a rotational or rolling motion along the surface (e.g., the upper surface) of the buffer member (150) to disperse the impact force applied to the buffer member (150).

[0056] The predetermined angle (θ) formed by the second plate (130) and the first plate (120) when the buffer member (150) and the first rotation member (160) come into contact (or collide) may be set by considering the range in which the initial contact point (e.g., contact point (P1) of FIG. 7) between the buffer member (150) and the first rotation member (160) can be located on the flat surface (1521) of the buffer member (150) described later at the moment when the buffer member (150) and the first rotation member (160) come into contact (or collide), and the range in which the first rotation member (160) can maintain contact with the buffer member (150) in the closed state of the compression device (100). For example, the predetermined angle (θ) may correspond to about 25°.

[0057] FIG. 5 is a side view of the contact state between the buffer member and the first rotation member according to one embodiment of the present disclosure.

[0058] FIG. 6 is a front view of the contact state between the buffer member and the first rotation member according to one embodiment of the present disclosure.

[0059] FIG. 5 and FIG. 6 are cross-sectional views, respectively, of the first rotating member (160) aligned with the central axis (CL) of the buffer member (150) when viewed from the side (e.g., in the +y-axis direction) and the front (e.g., in the +x-axis direction).

[0060] Referring to FIGS. 5 and 6, a buffer member (150) according to an example may include a body portion (151) and a head portion (152).

[0061] According to one example, a space (151a) may be formed on the inside of the body portion (151) to accommodate at least a portion of the head portion (152). A buffer solution such as gas and / or oil may be accommodated in the space (151a) of the body portion (151).

[0062] According to one example, the head portion (152) may be accommodated by being inserted into, at least in part, the space (151a) of the body portion (151). In one example, the head portion (152) may vertically move in the up-and-down direction (e.g., +z-axis direction) in the space (151a) depending on whether an external force is applied. When an external force (e.g., an impact force due to contact (or collision) with the first rotating member (160) when the second plate (e.g., the second plate (130) of FIG. 1) rotates) is applied to the head portion (152), the head portion (152) moves vertically along the space (151a), and as the buffer solution flows in response to the vertical movement of the head portion (152), a buffering operation of the buffering member (150) may be performed.

[0063] In one example, the upper surface (1520) of the head portion (152) may include a flat portion (1521) and an edge portion (1522). In one example, the flat portion (1521) may form a central portion of the upper surface (1520) of the head portion (152). In one example, the flat portion (1521) may be formed as a flat surface. In one example, the edge portion (1522) may form an edge of the upper surface (1520) of the head portion (152). In one example, the edge portion (1522) may surround the flat portion (1521). In one example, the edge portion (1522) may be rounded to have a predetermined curvature.

[0064] According to some embodiments, the upper surface (1520) of the head portion (152) may be formed as a curved surface having a predetermined curvature, replacing the flat portion (1521) and the edge portion (1522).

[0065] According to one example, the first rotating member (160) may include a rotating shaft (161) and a roller (162). In one example, the rotating shaft (161) may extend in a horizontal direction (e.g., in the ± y-axis direction). In one example, the rotating shaft (161) may be axially coupled to the roller (162) by penetrating the center of the roller (162). In one example, the rotating shaft (161) may be rotatably coupled to a bottom surface of a second plate (e.g., the bottom surface (130a) of the second plate (130) of FIG. 1). In one example, the rotating shaft (161) may have a cylindrical shape. In one example, the roller (162) may have a disc shape.

[0066] FIG. 7 is a drawing for explaining the positional relationship between the buffer member and the first rotating member during operation of the compression device according to one embodiment of the present disclosure.

[0067] FIG. 8 is a drawing for explaining the positional relationship between the buffer member and the first rotating member during operation of the compression device according to one embodiment of the present disclosure.

[0068] FIG. 9 is a drawing for explaining the positional relationship between the buffer member and the first rotating member during operation of the compression device according to one embodiment of the present disclosure.

[0069] FIG. 7 (a) is a drawing showing the position of the first rotating member (160) when the buffer member (150) and the first rotating member (160) come into contact (or collide) during the operation of the compression device (e.g., the compression device (100) of FIG. 1). FIG. 7 (b) is a drawing showing the position of the first rotating member (160) when the operation of the compression device (100) is completed (e.g., in a closed state).

[0070] Referring to (a) of FIG. 7, when the compression device (100) operates, the second plate (130) rotates, and when the angle of the second plate (130) with respect to the first plate (120) reaches a predetermined angle (θ) (e.g., 25°), the first rotational member (160) and the buffer member (150) come into contact (or collide) with each other. At this time, the initial contact point (P1) between the first rotational member (160) and the buffer member (150) may be located at the flat portion (1521) of the head portion (152). The head portion (152) of the buffer member (150) moves downward (e.g., in the -z-axis direction) due to the impact force caused by the collision and performs a buffering operation. Accordingly, the rotational speed of the second plate (130) decreases. At the same time, the first rotating member (160) rotates forward (e.g., in the +x-axis direction) along the upper surface (1520) of the head portion (152).

[0071] Referring to (b) of Fig. 7, when the operation of the compression device (100) is completed and the first plate (110) and the second plate (120) are in a closed state facing each other, the rotation of the first rotation member (160) stops. At this time, the final contact point (P2) between the first rotation member (160) and the buffer member (150) may be located on the upper surface (1520) of the head portion (152), specifically, on the edge portion (1522) of the head portion (152).

[0072] FIG. 8 is a drawing showing the position of the first rotating member (160) during the operation of the compression device (100) when the first rotating member (160) is aligned with the central axis (CL) of the buffer member (150) when the operation of the compression device (100) is completed (e.g., in a closed state).

[0073] FIG. 8 (a) is a drawing showing the position of the first rotating member (160) when the buffer member (150) and the first rotating member (160) come into contact (or collide) during the operation of the compression device (100), and FIG. 8 (b) is a drawing showing the position of the first rotating member (160) when the operation of the compression device (100) is completed (e.g., closed state).

[0074] Referring to (a) of FIG. 8, when the compression device (100) operates, the second plate (130) rotates and when the angle of the second plate (130) with respect to the first plate (120) reaches a predetermined angle (θ) (e.g., 25°), the first rotational member (160) and the buffer member (150) come into contact (or collide) with each other. At this time, the initial contact point (P3) of the first rotational member (160) and the buffer member (150) may be located at the edge portion (1522) of the head portion (152). When the first rotational member (160) makes contact at the initial contact point (P3), an impact force may be transmitted to the head portion (152) along an imaginary line (L) connecting the initial contact point (P3) and the center (C) of the first rotational member (160). In this case, as fatigue due to collision accumulates in a specific area of ​​the head portion (152) (e.g., edge portion (1522)), damage to the head portion (152) may occur during long-term use of the compression device (100). At the same time, the buffer member (150) performs the aforementioned buffering operation, and the first rotating member (160) rotates forward along the upper surface (1520) of the head portion (152).

[0075] Referring to (b) of FIG. 8, when the operation of the compression device (100) is completed and the first plate (110) and the second plate (120) are in a closed state facing each other, the rotation of the first rotation member (160) stops. At this time, the final contact point (P4) between the first rotation member (160) and the buffer member (150) may be located at the flat portion (1521) of the head portion (152). For example, the final contact point (P4) may be located at a point passing through the central axis (CL) of the head portion (152) or a point adjacent to the central axis (CL) of the head portion (152).

[0076] FIG. 9 is a drawing showing the position of the first rotating member (160) during operation of the compression device (100) when the first rotating member (160) comes into contact (or collides) with the central axis (CL) of the buffer member (150) at a point that coincides with the central axis (CL) of the compression device (100).

[0077] FIG. 9 (a) is a drawing showing the position of the first rotating member (160) when the buffer member (150) and the first rotating member (160) come into contact (or collide) during the operation of the compression device (100), and FIG. 9 (b) is a drawing showing the position of the first rotating member (160) when the operation of the compression device (100) is completed (e.g., in a closed state).

[0078] Referring to (a) of FIG. 9, when the compression device (100) operates, the second plate (130) rotates and when the angle of the second plate (130) with respect to the first plate (120) reaches a predetermined angle (θ) (e.g., 25°), the first rotational member (160) and the buffer member (150) come into contact (or collide) with each other. At this time, the initial contact point (P5) between the first rotational member (160) and the buffer member (150) may be located at a point passing through the central axis (CL) of the head part (152) among the flat portions (1521) of the head part (152) or at a point adjacent to the central axis (CL) of the head part (152). At the same time, the buffer member (150) performs the aforementioned buffering operation, and the first rotational member (160) rotates forward along the upper surface (1520) of the head part (152).

[0079] Referring to (b) of FIG. 9, when the operation of the compression device (100) is completed and the first plate (110) and the second plate (120) are brought into a closed state where they face each other, the rotation of the first rotation member (160) stops. At this time, the first rotation member (160) may be separated from the upper surface (1520) of the buffer member (150) and positioned in front (e.g., in the +x-axis direction) of the buffer member (150). In the closed state of the compression device (100), when the second plate (130) is opened to restart the compression device (100), the first rotation member (160) may get caught on or collide with the edge portion (1522) of the head portion (152) in front of the buffer member (150), and there is a concern that the buffer member (150) may be damaged when the compression device (100) is used for a long period of time.

[0080] In order to avoid problems that may arise depending on the positional relationship between the first rotating member (160) and the buffer member (150) illustrated in the aforementioned FIGS. 8 and 9, as illustrated in FIG. 7, the initial contact point between the first rotating member (160) and the buffer member (150) may be designed to be located within the flat portion (1521) of the head portion (152), and the final contact point between the first rotating member (160) and the buffer member (150) may be located within a range that does not deviate from the upper surface (1520) of the head portion (152).

[0081] FIG. 10 is a drawing showing the positional relationship between a buffer member and a first rotating member during operation of a compression device according to one embodiment of the present disclosure.

[0082] FIG. 11 is a drawing showing a contact state between a first rotating member and a second rotating member during operation of a compression device according to one embodiment of the present disclosure.

[0083] FIG. 10 (a) is a drawing showing the position of the first rotating member (160) when the buffer member (250) and the first rotating member (160) come into contact (or collide) during the operation of the compression device (e.g., the compression device (100) of FIG. 1). FIG. 10 (b) is a drawing showing the position of the first rotating member (160) when the operation of the compression device (100) is completed (e.g., in a closed state).

[0084] Fig. 11 is a cross-sectional view viewed from the front (e.g., in the +x-axis direction) of the first rotating member (160) in contact with (or aligned with) the central axis (CL) of the buffer member (250) during operation of the compression device (100).

[0085] Referring to FIGS. 10 and 11, a buffer member (250) according to an example may include a body portion (e.g., body portion (151) of FIG. 5) and a head portion (252). The body portion and head portion (252) of the buffer member (250) may be configured to be substantially identical in structure and / or shape to the body portion (151) and head portion (e.g., head portion (152)) illustrated in FIGS. 5 and 6 described above, and therefore, only the parts that differ will be described below.

[0086] According to one example, the buffer member (250) may further include a second rotation member (253). In one example, the second rotation member (253) may be fitted into a coupling member (2521) provided on the upper portion of the head portion (252). However, the present disclosure is not limited thereto, and the second rotation member (253) may be fixed to the upper portion of the head portion (252) in various ways. In one example, the second rotation member (253) may be provided to rotate or roll while contacting the first rotation member (160) at a predetermined angle (θ) of the second plate (130) with respect to the first plate (120) during the operation of the compression device (100). For example, the second rotation member (253) may have a roller or ball shape. In this case, when the compression device (100) is in operation, the first rotating member (160) and the second rotating member (253) contact each other and rotate and / or move in a rolling motion, thereby dispersing the impact force applied to the buffer member (250).

[0087] The configuration of the first rotation member (160a) of FIGS. 10 and 11 may be all or part of the same as the configuration of the first rotation member (160) of FIGS. 1 to 9.

[0088] According to one example, a groove (1621) may be formed on the surface of the roller (162a) of the first rotating member (160a). In one example, the groove (1621) may have a concave shape from the outside. In one example, the groove (1621) may have a radius of curvature greater than the radius of curvature of the second rotating member (253) so that the first rotating member (160a) and the second rotating member (253) come into point contact. In this case, when the first rotating member (160a) and the second rotating member (253) come into contact, the rotation or rolling motion of the second rotating member (253) may be guided by the groove (1621).

[0089] FIG. 12 is a drawing showing the positional relationship between a buffer member and a first rotating member during operation of a compression device according to one embodiment of the present disclosure.

[0090] Figure 12 (a) is a drawing showing the position of the first rotating member (160) when the buffer member (250) and the first rotating member (160) collide during the operation of the compression device (100). Figure 12 (b) is a drawing showing the position of the first rotating member (160) when the operation of the compression device (100) is completed (e.g., closed state).

[0091] The configuration of the buffer member (250a) of Fig. 12 may be all or part of the same as the configuration of the buffer member (250) of Figs. 9 to 11.

[0092] Referring to FIG. 12, a buffer member (250) according to an example may include a body portion (e.g., the body portion (151) of FIG. 5), a head portion (252), a second rotational member (253), and an elastic member (254). In one example, the elastic member (254) may be located on the lower side (e.g., in the -z-axis direction) of the second rotational member (253). In one example, the elastic member (254) may be disposed between the second rotational member (253) and the head portion (252). For example, the elastic member (254) may be accommodated in a space (252a) formed by a coupling portion (2521) of the head portion (252) and may be surrounded by the coupling portion (2521). In one example, the elastic member (254) may be elastically deformed in an up-and-down direction (e.g., in the ±z-axis direction) within the space (252a) by an external force.

[0093] For example, when the first rotating member (160) and the second rotating member (253) come into contact (or collide) due to the operation of a compression device (e.g., the compression device (100) of FIG. 1), an impact force is transmitted to the elastic member (254) through the second rotating member (253), and the elastic member (254) can be compressed. In this case, the impact force caused by the collision between the first rotating member (160) and the second rotating member (253) can be additionally distributed through the elastic member (254).

[0094] At the same time, when the compression device (100) is in operation, the first rotating member (160) and the second rotating member (253) contact each other and rotate and / or roll while dispersing the impact force applied to the buffer member (250).

[0095] A compression device (100) according to an example may include a first plate (120), a second plate (130) rotatably connected to the first plate (120) via a hinge device (140), a buffer member (150, 250) disposed on the first plate (120), and a first rotational member (160) positioned to contact the buffer member (150, 250) when the second plate (130) rotates in a direction facing the first plate (120), and rotates or rolls along the surface of the buffer member (150, 250) by the contact.

[0096] According to an example, the buffer member (150, 250) and the first rotation member (160) can come into contact with each other when the angle of the second plate (130) with respect to the first plate (120) reaches a preset angle (θ).

[0097] As an example, the preset angle (θ) may correspond to 25 degrees.

[0098] According to an example, the above-mentioned buffer member (150, 250) may have a hydraulic buffer structure.

[0099] According to one example, the buffer member (150) may include a body part (151) having a receiving part (151a) provided on the inside; and a head part (152) that is received in the receiving part (151a) of the body part (151) and moves vertically within the receiving part (151a) depending on whether an external force is applied.

[0100] According to one example, the upper surface (1520) of the head portion (152) may include an edge portion (1522) that forms the edge of the upper surface (1520) and is rounded to have a predetermined curvature, and a flat portion (1521) that is surrounded by the edge portion (1522) and is configured as a plane.

[0101] According to an example, the first rotating member (160) may be positioned so that the initial contact point (P1) with the buffer member (150) is located on the flat portion (1521) of the head portion (152).

[0102] According to one example, the first rotating member (160) may be positioned on the bottom surface (130a) of the second plate (130) such that the final contact point (P2) with the buffer member (150) is positioned on the upper surface (1520) of the head portion (152).

[0103] According to one example, the first rotating member (160) may have a roller structure that rotates when in contact with the buffer member (150).

[0104] According to an example, the first rotating member (160) may have a ball caster structure that moves in a cloud when in contact with the buffer member (150).

[0105] According to one example, the first plate (120) may include a mounting portion (121) that is sunken into the upper surface of the first plate (120) and on which a compression target is mounted.

[0106] According to one example, the first rotating member (160) may be placed on the second plate (130) so as to maintain contact with the buffer member (150) in the closed state of the compression device (100).

[0107] According to an example, the closed state of the compression device (100) may be a state in which the second plate (130) rotates in a direction approaching the first plate (120) and is arranged to face each other.

[0108] According to one example, the compression device (100) may further include a base plate (110) disposed on the lower side of the first plate (120) to support the first plate (120) and the second plate (130).

[0109] According to one example, the compression device (100) may further include an up-and-down driving unit (170) disposed between the first plate (120) and the base plate (110) and configured to adjust the height of the compression device (100).

[0110] According to one example, the buffer member (250) may include a body part having a receiving part provided on the inside; a head part (252) that is received in the receiving part of the body part and moves vertically within the receiving part depending on whether an external force is applied; and a second rotating member (253) that is disposed above the head part (252) and rotates or rolls together with the first rotating member (160) when in contact with the first rotating member (160).

[0111] According to one example, the buffer member (250) may further include an elastic member (254) that is disposed between the head portion (252) and the second rotation member (253) and applies elastic force to the second rotation member (253).

[0112] According to an example, the second rotating member (253) may have a spherical shape.

[0113] According to an example, a concave groove (1611) may be formed on the surface of the first rotating member (160).

[0114] In one example, the radius of curvature of the groove (1611) may be greater than the curvature of the second rotating member (253).
