Description

Dial-type handle and pressure device

[0001] The present invention relates to a dial-type handle and a pressure device, and more specifically, to a dial-type handle and a pressure device that sets the rotatable allowable angle of a handle through a dial method.

[0002] A pressure device is used to apply pressure to an object, such as a semiconductor package, within a test socket to inspect its electrical characteristics. This device securely fixes the object in the socket and provides the pressure necessary to accurately measure electrical characteristics. In particular, the pressure device includes a handle that controls the degree of elevation of the pusher through rotation, allowing the user to adjust the appropriate pressure according to the thickness and characteristics of the object.

[0003] Conventional handles present the inconvenience of requiring different handles to be installed and operated depending on the thickness of the object being inspected, or even when using the same handle, the amount of rotation must be adjusted based on the user's sense of touch. This method has the problem of making it difficult to ensure uniformity in the amount of rotation. In particular, a method relying on the user's sense of touch is susceptible to variations depending on the user's skill level or physical condition, which reduces inspection reliability.

[0004] Prior art No. 10-2259642 discloses a method for adjusting the amount of rotation of a handle by tightening a stopper screw. However, this method involves inconvenience during the work process because the user must directly tighten or loosen the screw, and there is still an inconvenience that reduces work efficiency in repetitive work environments.

[0005] Therefore, there is a need to develop a means to handle inspection targets of various thicknesses more simply. Through this, technology is required to simultaneously improve the operational efficiency and reliability of the inspection process.

[0009] To solve the aforementioned problems, the present invention aims to provide a dial-type handle and a pressure device that can easily set a rotatable allowable angle.

[0010] To achieve the above-mentioned purpose, a dial-type handle that presses an object to be inspected by rotation to inspect the electrical characteristics of the object to be inspected may include: a body part having a guide groove formed extending along the circumferential direction on one surface; and a dial part having a blocking part that moves along the guide groove to set a rotatable allowable angle of the dial-type handle.

[0011] In addition, in an embodiment of the present invention, when the dial portion rotates in one direction, the blocking portion can move in one direction along the guide groove to increase the allowable angle.

[0012] In addition, in an embodiment of the present invention, when the dial portion rotates in the other direction, the blocking portion can move along the guide groove in the other direction to reduce the allowable angle.

[0013] Additionally, in an embodiment of the present invention, the dial portion includes a fixed portion, and the body portion includes a plurality of fixed grooves provided along the circumferential direction so that the fixed portion can enter, and the dial portion may be subjected to a setting mode in which a fixed key of the fixed portion can detach from one of the plurality of fixed grooves and rotate.

[0014] In addition, in an embodiment of the present invention, the dial portion may include an identification portion formed to allow visual confirmation of a gauge formed in the circumferential direction of the body portion.

[0015] In addition, in an embodiment of the present invention, the dial portion may be capable of relative rotation with respect to the body portion in a setting mode, limited to the angle of the guide groove, and the body portion and the dial portion may be capable of rotating together in a driving mode, limited to the allowable angle.

[0016] Meanwhile, a pressurizing device according to an embodiment of the present invention, in a pressurizing device for pressurizing an object to be inspected for inspecting electrical characteristics, comprises: a dial-type handle; and a support member equipped with a stopper; wherein the dial-type handle comprises a body member having a guide groove formed extending along a circumferential direction on one surface, and a dial member having a blocking member that moves along the guide groove to set an allowable angle at which the dial-type handle can rotate, and wherein the dial-type handle can pressurize the object to be inspected by rotating until the stopper contacts the blocking member.

[0017] The present invention has the effect of being able to handle inspection objects of various thicknesses without relying on the user's senses by pre-setting the allowable angle of the dial part.

[0018] In addition, the present invention allows the rotatable allowable angle of the dial-type handle and the pressure device to be easily set through a rotary dial portion.

[0028] Furthermore, all conditional terms and embodiments listed in this specification are, in principle, explicitly intended only for the purpose of enabling an understanding of the concept of the invention and should be understood as not being limited to the embodiments and conditions specifically listed as such.

[0029] The aforementioned objectives, features, and advantages will become more apparent through the following detailed description of the invention in conjunction with the attached drawings, and accordingly, a person skilled in the art to which the invention pertains will be able to easily implement the technical concept of the invention.

[0030] The embodiments described herein will be explained with reference to cross-sectional and / or perspective views, which are exemplary illustrations of the present invention. The dimensions, etc., of the components shown in these drawings may be exaggerated for effective explanation of the technical content. The shapes of the exemplary illustrations may be modified due to manufacturing technology and / or tolerances, etc.

[0031] In describing various embodiments, for convenience, the same name and the same reference number will be assigned to components performing the same function, even if the embodiments are different. Additionally, the expression 'at least one of A, B, and C' means composed of a combination of one, two, or three of A, B, and C. Furthermore, the term 'rotation' may be used with the same meaning as rotational motion.

[0032] Furthermore, for convenience, the configuration and operation already described in other embodiments will be omitted.

[0033] First, we will examine the pressurizing device (1) (hereinafter referred to as the 'pressurizing device') according to an embodiment of the present invention.

[0034] FIG. 1 is a drawing showing a dial-type handle (10) and a pressure device (1) including the same according to an embodiment of the present invention.

[0035] The pressurizing device (1) can pressurize the object to be inspected (2) to inspect the electrical characteristics of the object to be inspected (2). The pressurizing device (1) may include a dial-type handle (10); and a support member (40) equipped with a stopper (41).

[0036] A dial-type handle (10) may include a body part (200) having a guide groove (210) formed extending along the circumferential direction on one surface, and a dial part (100) having a blocking part (110) that moves along the guide groove (210) to set an allowable angle (AA) at which the dial-type handle (10) can rotate. The dial-type handle (10) can rotate until the stopper (41) contacts the blocking part (110) to press the inspection object (2).

[0037] The pressure device (1) may include a dial-type handle (10), a bolt part (20), a pusher part (50), a socket part (30), and a support part (40). The pressure device (1) may include more components and fewer components, and is not limited to the configuration described above.

[0038] The dial-type handle (10) can be rotated by being grasped by a user or an external device. The dial-type handle (10) can rotate the bolt part (20) and translate the pusher part (50) according to the rotational movement.

[0039] The bolt portion (20) can be combined with the dial-type handle (10) and rotate together with the rotational movement of the dial-type handle (10). The bolt portion (20) can be combined with the support portion (40). Through the threads of the bolt portion (20) and the support portion (40), the bolt portion (20) and the support portion (40) can be combined to enable relative rotational movement and relative translational movement.

[0040] The bolt portion (20) can rotate and translate with respect to the support portion (40). The rotational movement of the bolt portion (20) can be performed in clockwise and counterclockwise directions with the vertical axis as the central axis, and the translational movement of the bolt portion (20) can be performed in the vertical direction.

[0041] The pusher part (50) is combined with the bolt part (20) and can move translationally together with the bolt part (20) according to the translational movement of the bolt part (20). The pusher part (50) can lower to press the object to be inspected (2) and rise to release the pressure on the object to be inspected (2).

[0042] When the pusher part (50) presses the object to be inspected (2), the inspection pin (31) provided in the socket part (30) comes into contact with the external terminal (not shown) of the object to be inspected (2) to inspect the electrical characteristics of the object to be inspected (2).

[0043] The socket portion (30) can provide a space for the object to be inspected (2) to be placed. When the object to be inspected (2) is placed in the socket portion (30) and pressurized, the socket portion (30) can inspect the electrical characteristics of the object to be inspected (2) by exchanging electrical signals with the object to be inspected (2).

[0044] At this time, the object to be inspected (2) may be one of electronic components such as a semiconductor package, integrated circuit, electrical device, MEMS device, sensor, etc., and is not limited to those described above. The socket portion (30) can be fixed despite the movement of the dial-type handle (10), bolt portion (20), and pusher portion (50).

[0045] The support member (40) can be combined with the bolt member (20). The support member (40) can be fixed by being combined with the socket member (30), but it can also be fixed by an external device.

[0046] The support member (40) can be combined with the bolt member (20) to support the bolt member (20) so that it can rotate and translate. The support member (40) can be fixed despite the movement of the dial-type handle (10), the bolt member (20), and the pusher member (50).

[0047] The support member (40) may include a stopper (41). The stopper (41) may be provided protruding vertically from the support member (40). The stopper (41) may move along the guide groove (210) of the dial-type handle (10).

[0048] Specifically, the stopper (41) is fixed to the support member (40) and can move relative to the guide groove (210) as the dial-type handle (10) rotates.

[0049] The stopper (41) can prevent rotational movement of the dial-type handle (10). For example, the stopper (41) can be positioned at one end of the guide groove (210) according to the rotation of the dial-type handle (10) in one direction to prevent the dial-type handle (10) from rotating further, and can be positioned at the other end of the guide groove (210) according to the rotation of the dial-type handle (10) in the other direction to prevent the dial-type handle (10) from rotating further.

[0050] Next, we will examine the dial-type handle (10) (hereinafter referred to as the 'dial-type handle') according to an embodiment of the present invention.

[0051] FIG. 2 is a diagram showing the disassembled state of another dial-type handle (10) in an embodiment of the present invention.

[0052] The dial-type handle (10) can press the object to be inspected (2) by rotation to inspect the electrical characteristics of the object to be inspected (2). Specifically, the dial-type handle (10) can translate the pusher part (50) through rotational movement, and press the object to be inspected (2) through the translational movement of the pusher part (50).

[0053] Referring to FIG. 2, the dial-type handle (10) may include a body part (200) having a guide groove (210) formed extending along the circumferential direction on one surface; and a dial part (100) having a blocking part (110) that moves along the guide groove (210) to set a rotatable allowable angle (AA) of the dial-type handle (10).

[0054] The dial-type handle (10) may include a body part (200) and a dial part (100), and optionally may further include a gripping part (300).

[0055] The body portion (200) may include a guide groove (210) formed extending along the circumferential direction on one surface. Here, the circumferential direction may refer to a direction in which the angle increases or decreases relative to the center point of the body portion (200).

[0056] The guide groove (210) may be recessed or penetrated in the vertical direction (upward direction) to provide a space through which the stopper (41) of the support member (40) can enter. The guide groove (210) provides a space through which the stopper (41) can move between the first end and the other end, and can prevent the movement of the stopper (41) through the first end and the other end.

[0057] The body portion (200) may include a plurality of fixing grooves (220) arranged along the circumferential direction. The fixing grooves (220) may be recessed in a radial direction to provide a space into which the fixing key (131) can enter. That is, the plurality of fixing grooves (220) are arranged in a circumferential direction and, furthermore, the plurality of fixing grooves (220) may each be recessed in a radial direction.

[0058] By moving a fixing key (131) located in one of the plurality of fixing grooves (220) to another of the plurality of fixing grooves (220), the rotatable allowable angle (AA) of the dial handle (10) can be set or reset.

[0059] The dial portion (100) may include a ring-shaped dial body (140), a fixing portion (130) located at a first point in the circumferential direction of the dial body (140), and a blocking portion (110) located at a second point in the circumferential direction of the dial body (140), and optionally may include an identification portion (120) located at a third point in the circumferential direction of the dial body (140). The first point, the second point, and the third point may be any point on the dial body (140), and their positions are not limited.

[0060] The dial portion (100) can be rotatably coupled to the body portion (200). The dial portion (100) can rotate relative to the body portion (200) to set a rotatable allowable angle (AA) of the dial-type handle (10). The dial portion (100) and the body portion (200) can rotate together within the allowable angle (AA) range.

[0061] The fixed part (130) may be located on the dial body (140). The fixed part (130) may be coupled with the fixed groove (220) of the body part (200) to prevent relative rotational movement of the dial part (100). In driving mode, the fixed part (130) may be coupled with the fixed groove (220) of the body part (200) to prevent relative rotational movement of the dial part (100).

[0062] The fixed part (130) can be disengaged from the fixed groove (220) of the body part (200) to allow relative rotational movement of the dial part (100). In the setting mode, the fixed part (130) can be disengaged from the fixed groove (220) of the body part (200) to allow relative rotational movement of the dial part (100).

[0063] The setting mode sets the allowable angle (AA), allowing only the dial part (100) to rotate by operating the fixed part. Conversely, the driving mode allows the entire dial-type handle (10) to rotate only by the set allowable angle (AA).

[0064] The dial-type handle (10) according to an embodiment of the present invention can perform a constant rotational movement or a constant translational movement without relying on the user's senses by setting an allowable angle (AA), which is a range in which rotation is easily possible through a mutual switching method between a setting mode and a driving mode.

[0065] The blocking part (110) may be located on the dial body (140). The blocking part (110) may be located on one side of the dial body (140) and may be located in the guide groove (210) of the body part (200).

[0066] The blocking part (110) can move circumferentially along the guide groove (210) by the rotational movement of the dial part (100). The blocking part (110) can divide the space of the guide groove (210) in half, setting one side of the space as an allowable angle (AA) and the other side of the space as a limiting angle (RA) (see FIG. 5).

[0067] One side of the space corresponding to the allowable angle (AA) in the guide groove (210) can provide a space in which the stopper (41) of the support member (40) can enter and move. The other side of the space corresponding to the limiting angle (RA) in the guide groove (210) can provide a space in which the stopper (41) of the support member (40) cannot enter.

[0068] The identification part (120) may be located on the dial body (140). The identification part (120) may be formed to protrude radially from the dial body (140), but is not limited thereto. The identification part (120) may have a confirmation window (121) at its center to expose the gauge (230) of the body part (200) through the identification part (120).

[0069] The identification unit (120) can make it possible to visually check the gauge (230) formed in the circumferential direction. The user can visually check the gauge (230) of the body unit (200) through the confirmation window (121) of the identification unit (120) and numerically determine the range in which the current allowable angle (AA) is set.

[0070] The gauge (230) can be in the form of a scale, number, letter, etc., as a means to visually indicate the setting range of the allowable angle (AA), and is not limited to such a form.

[0071] The identification part (120) can be positioned to face the fixed part (130) based on the center point of the dial body (140). That is, the identification part (120) and the fixed part (130) can be positioned on the dial body (140) while maintaining a 180-degree separation angle from each other.

[0072] The gripping portion (300) can be coupled to the body portion (200). The gripping portion (300) can be gripped by a user or an external device and receive force from the user or an external device to rotate the dial-type handle (10). There may be multiple gripping portions (300), and each of the multiple gripping portions (300) can be coupled to the body portion (200) and gripped by a user or an external device. The gripping portion (300) can be coupled to the body portion (200) by a gripping pin (310).

[0073] Next, we will look at the allowable angle (AA) setting of the dial handle (10).

[0074] FIG. 3 is a drawing showing the upper part of a dial-type handle (10) in a first state according to an embodiment of the present invention. FIG. 4 is a drawing showing the lower part of a dial-type handle (10) in a first state according to an embodiment of the present invention. FIG. 5 is a drawing showing the lower part of a dial-type handle (10) in a second state according to an embodiment of the present invention.

[0075] Referring to FIGS. 3 and 4, in the first state, the dial-type handle (10) may have a blocking portion (110) located at the end of the guide groove (210). The blocking portion (110) may be formed to extend along the circumferential direction in a curved shape.

[0076] The blocking part (110) is provided with a concave shape on one side and can contact the stopper (41) through the one side. The concave shape can prevent wear of the blocking part (11) and the stopper (41) itself despite repeated contact between the blocking part (110) and the stopper (41).

[0077] The dial-type handle (10) can be set to have an allowable angle (AA) of 180 degrees in the first state. When the dial-type handle (10) rotates, the stopper (41) of the support member (40) can move from one side of the guide groove (210) toward the blocking member (110) in the other direction. That is, the dial-type handle (10) can rotate until the blocking member (110) comes into contact with the stopper (41).

[0078] The dial-type handle (10) can be limited to a rotation of 180 degrees, and when rotating 180 degrees, the pusher part (50) can be made to press the object to be inspected (2) through translational movement by a distance corresponding to the rotational movement.

[0079] Referring to FIG. 5, in the second state, the dial handle (10) can have the blocking part (110) positioned between both ends of the guide groove (210). In the second state, the allowable angle (AA) of the dial handle (10) can be set to 90 degrees.

[0080] When the dial-type handle (10) is rotated, the stopper (41) of the support member (40) can move from one side of the guide groove (210) toward the blocking member (110). That is, the dial-type handle (10) can be rotated until the blocking member (110) comes into contact with the stopper (41).

[0081] The dial-type handle (10) can be limited to a rotation of 90 degrees, and when rotating 90 degrees, the pusher part (50) can press the object to be inspected (2) through translational movement by a distance corresponding to the rotational movement.

[0082] Although the first and second states have been described using FIGS. 3 to 5 as examples, the dial-type handle (10) is not limited to the first and second states for state switching, and can switch states as many times as there are fixed grooves (220). In addition, the allowable angle (AA) is not limited to two angles of 180 degrees or 90 degrees, and the allowable angle (AA) can be set as much as there are times corresponding to the distance occupied by the multiple fixed grooves (220).

[0083] Next, we will look at the setting mode and driving mode of the dial-type handle (10).

[0084] FIG. 6 is a drawing showing a fixing part (130) and a fixing groove (220) in an embodiment of the present invention.

[0085] The fixed part (130) may include a fixed key (131), a fixed button (132), an elastic body (133), and a key receiving part (134).

[0086] The fixing key (131) can enter the fixing groove (220) to prevent rotation of the dial portion (100). The fixing key (131) can enter one of the plurality of fixing grooves (220) to prevent rotation of the dial portion (100). At this time, the allowable angle (AA) may be in a state where the setting is completed.

[0087] The fixing key (131) can detach from the fixing groove (220) to allow rotation of the dial portion (100). The fixing key (131) can detach from one of the plurality of fixing grooves (220) to allow rotation of the dial portion (100). At this time, the allowable angle (AA) may be set within a variety of ranges.

[0088] The fixing button (132) can be connected to the fixing key (131). When the fixing button (132) is pressed by the user, the fixing button (132) moves toward the center of the dial portion (100) and compresses the elastic body (133) toward the center, thereby disengaging the fixing key (131) from the fixing groove (220).

[0089] When the fixed button (132) is released by the user, the elastic body (133) is restored and / or stretched, and the fixed button (132) is pushed in the radial direction of the dial part (100) to insert the fixed key (131) into the fixed groove (220).

[0090] The elastic body (133) may be positioned in the key receiving portion (134), and may be configured such that one side contacts the inner wall of the key receiving portion (134) and the other side contacts the fixing button (132). The elastic body (133) may be positioned between the inner wall of the key receiving portion (134) and the fixing button (132) to apply force to the key receiving portion (134) and the fixing button (132).

[0091] When the user presses the fixed button (132), the elastic body (133) is compressed, allowing the fixed key (131) to move. Conversely, when the user releases the press of the fixed button (132), the elastic body (133) is restored, allowing the fixed key (131) to move. The key receiving portion (134) can receive the elastic body (133) and the fixed button (132).

[0092] In the setting mode, the fixing key (131) of the fixed part (130) may be in a state where it is detached from the fixing groove (220). That is, the fixing key (131) of the fixed part (130) may be detached from one of the plurality of fixing grooves (220) so that the dial part (100) can be rotated in the setting mode.

[0093] In the setting mode, when the dial portion (100) rotates in one direction, the blocking portion (110) can move along the guide groove (210) in one direction to increase the allowable angle (AA). Conversely, when the dial portion (100) rotates in the other direction, the blocking portion (110) can move along the guide groove (210) in the other direction to decrease the allowable angle (AA).

[0094] In the driving mode, the fixing key (131) of the fixed part (130) may be in a state where it has entered the fixing groove (220). That is, the fixing key (131) of the fixed part (130) may enter one of the plurality of fixing grooves (220) to result in a driving mode in which the dial part (100) cannot rotate (or the dial part (100) and the body part (200) can rotate together). The dial part (100) cannot rotate relative to the body part (200) and can rotate together with the body part (200).

[0095] According to an embodiment of the present invention, a user can switch between a setting mode and a driving mode by only pressing the fixed part (130), and can easily set the allowable angle (AA) by only rotating the dial part (100) while pressing the fixed part (130).

[0096] Next, we examine the process in which the pressurizing device (1) pressurizes the object to be inspected (2).

[0097] FIG. 7 is a drawing showing a dial-type handle (10) and a pressure device (1) applied to a thin (D1) inspection object (2) in an embodiment of the present invention. FIG. 8 is a drawing showing a dial-type handle (10) and a pressure device (1) applied to a thick (D2) inspection object (2) in an embodiment of the present invention.

[0098] Referring to FIG. 7, in order for the pressurizing device (1) to pressurize a relatively thin (D1) inspection object (2), the dial handle (10) can rotate over a larger range and translate over a larger range.

[0099] For example, in setting mode, the dial portion (100) can rotate relative to one direction or the other to set the allowable angle (AA) to 180 degrees. Subsequently, in driving mode, the dial portion (100) can rotate together with the body portion (200) in one direction to cause the pusher portion (50) to press the object to be inspected (2).

[0100] The dial-type handle (10) can rotate 180 degrees and translate vertically by a length corresponding to 180 degrees.

[0101] Referring to FIG. 8, in order for the pressurizing device (1) to pressurize a relatively thick (D2) inspection object (2), the dial handle (10) can rotate in a smaller range and translate in a smaller range.

[0102] For example, in setting mode, the dial portion (100) can rotate relative to one direction or the other to set the allowable angle (AA) to 90 degrees. Subsequently, in driving mode, the dial portion (100) can rotate together with the body portion (200) in one direction to cause the pusher portion (50) to press the object to be inspected (2).

[0103] The dial-type handle (10) can rotate 90 degrees and translate vertically by a length corresponding to 90 degrees.

[0104] Meanwhile, the angle extended in the circumferential direction of the guide groove (210) may be 0 to 360 degrees. Accordingly, the allowable angle may be set between 0 and 360 degrees. Although 180 degrees and 90 degrees were given as examples in FIGS. 7 and FIGS. 8 described above, respectively, they are not limited thereto.

[0105] The dial-type handle (10) according to an embodiment of the present invention can set an allowable angle (AA) in advance before the pressure device (1) pressures the object to be inspected (2), thereby setting the rotational movement range and translational movement range of the pressure device (1) without relying on the user's senses.

[0106] The pressurizing device (1) according to an embodiment of the present invention is provided with a dial-type handle (10) that can be rotatably rotated within a preset allowable angle (AA), thereby allowing the inspection target (2) to be repeatedly pressed with a uniform force and improving the inspection reliability of the inspection target (2).
