Detailed Description

The present application will now be described in detail with reference to specific embodiments thereof as illustrated in the accompanying drawings. These embodiments are not intended to limit the present application, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present application.

Referring to fig. 1 to 5b, an embodiment of the present invention provides a handheld clamping device 100, which can be specifically applied to the taking and transferring of PCBA circuit board materials, the component taking and placing of optical modules, and the like, for example, manually taking and placing the component by gripping the clamping device 100 and utilizing the clamping device 100, thereby realizing the transferring of the component, and avoiding the quality hidden trouble of products caused by directly contacting the component with hands.

As shown in fig. 1, the holding jig 100 includes an outer tube 10, an inner core rod 20, and a pair of jaws 30, and as shown in fig. 2, further includes a first resilient mechanism 40.

Referring to fig. 2 and 3, the outer tube 10 is a hollow longitudinal tube structure having a hollow inner cavity 15 extending back and forth along a length direction thereof, a first opening 151 at a rear end thereof, and a second opening 152 at a front end thereof, and the inner cavity 15 of the outer tube 10 is communicated with the outside through the first opening 151 and the second opening 152, respectively.

In the present embodiment, the first opening 151 is formed at the rear end surface of the rear end portion of the outer sleeve 10, which is open toward the rear of the outer sleeve 10, but it is understood that the present invention is not limited thereto, and for example, in a modified embodiment, the first opening 151 may be provided at the peripheral wall of the rear end portion of the outer sleeve 10 (for example, the rear end portion of the outer sleeve 10 is modified to be a side opening and the rear end surface is closed), which is open toward the side of the outer sleeve 10. Similarly, in the present embodiment, the second opening 152 is formed at the front end surface of the front end portion of the outer tube 10, which is open toward the front of the outer tube 10, but it is understood that the present application is not limited to this as well, and for example, in a modified embodiment, the second opening 152 may be provided at the peripheral wall of the front end portion of the outer tube 10 (for example, the front end portion of the outer tube 10 is modified to be open to the side and the front end surface is closed), which is open toward the side of the outer tube 10.

A pair of jaws 30 are disposed opposite to each other on the left and right at the front end portion of the outer sleeve 10. In this embodiment, both jaws of the pair of jaws 30 are movably connected to the outer sleeve 10 to have a release state (shown in fig. 5 b) in which they are spaced apart from each other and a grip state (shown in fig. 5 a) in which they are spaced apart from each other. It will be understood that the present application is not limited thereto, and that, for example, in an alternative embodiment, only one of the pair of jaws 30 may be fixedly connected to the outer sleeve 10, while the other jaw is movably connected to the outer sleeve 10, and that the pair of jaws 30 may also assume two different states, namely the unclamped state and the clamped state. In the present application, the movably arranged clamping jaw 30 is defined as a movable clamping jaw 30 to distinguish from the fixedly arranged clamping jaw 30, and of course, in the present embodiment, both clamping jaws 30 are movable clamping jaws 30.

The core bar 20 and the first resilient mechanism 40 are each adapted to drive the movable jaw 30 in movement to cause the pair of jaws 30 to change between the undamped condition and the clamped condition. For example, in the present embodiment, the core rod 20 is used to drive the pair of clamping jaws 30 to change from the clamping state to the unclamping state, and the corresponding first elastic mechanism 40 is used to drive the pair of clamping jaws 30 from the unclamping state to the clamping state so as to clamp the circuit board or the component; of course, in an alternative embodiment, the inner core bar 20 may be used to drive the pair of clamping jaws 30 from the unclamped state to the clamped state to clamp the circuit board or the component, and the corresponding first elastic mechanism 40 may be used to drive the pair of clamping jaws 30 from the clamped state to the unclamped state.

Referring specifically to fig. 4, the inner core rod 20 includes a rod body 22 inserted into the inner cavity 15 of the outer sleeve 10 and an operating portion 21 located at the first opening 151. The operation portion 21 is exposed at the first opening 151 for receiving a user's touch (e.g. pressing in the present embodiment, or pulling, toggling in the modified embodiment), and drives the rod 22 to move under the user's touch, so that the front end 222 of the rod 22 drives the pair of jaws 30 to change from the clamping state to the unclamping state (or from the unclamping state to the clamping state in the modified embodiment). Correspondingly, the first elastic mechanism 40 is disposed at the front end portion of the outer sleeve 10, and when the operation portion 21 loses touch by the user, for example, when the user releases the operation portion 21, the first elastic mechanism 40 drives the pair of clamping jaws 30 to reset (i.e., to be in a recovery state).

Thus, the clamping device 100 provided in the present technology adopts a pen-shaped structure, and a manual operation can change the clamping state of the pair of clamping jaws 30 from the clamping state to the unclamping state or from the unclamping state to the clamping state by holding the outer sleeve 10 and touching the operating portion 21 with fingers, and the resetting of the pair of clamping jaws 30 is realized in combination with the arrangement of the first elastic mechanism 40, so as to realize clamping or unclamping, and the structure is simple, the operation is convenient, and the cost is low; in the processes of taking and transferring components, the components can be clamped and loosened, so that the quality hidden danger of products caused by manual direct contact of the components with hands is avoided. In addition, the clamping jaw 30 can be made of antistatic TPU material, so that electrostatic interference between hands and products can be effectively isolated.

In the preferred embodiment of the drawings, when the operating portion 21 is touched by a finger, the pair of clamping jaws 30 is changed from the clamping state to the unclamping state, when the operating portion 21 is unclamped, the first elastic mechanism 40 drives the pair of clamping jaws 30 to approach the clamping state, so as to clamp a component, that is, the clamping jaws 30 are driven to clamp the component by the acting force of the first elastic mechanism 40, and at this time, no external force is required to touch, so that when the component is clamped by the clamping device 100 (that is, when the pair of clamping jaws 30 is in the clamping state), the user does not need to touch the operating portion 21 continuously, and it is avoided that the component is damaged by being clamped or the component is dropped due to excessive force application by the user in the process of transferring the component, and the transferring process is too small, firm and stable.

In this embodiment, the operation portion 21 drives the rod 22 to move forward when triggered by the user, so that the front end portion 222 of the rod 22 drives the pair of clamping jaws 30 to change from the clamping state to the releasing state, that is, the user triggers the operation portion 21 to move the rod 22 forward. Of course, the application is not limited to this, and in a modified embodiment, the user may touch the operation portion 21 to move the rod 22 backward.

Further, referring to fig. 4, the movable clamping jaw 30 is in wedge-shaped fit with the front end 222 of the rod 22, and in detail, the movable clamping jaw 30 is provided with an inclined surface 302, when the operating portion 21 drives the rod 22 to move forward under the touch of the user, the front end 222 of the rod 22 abuts against the inclined surface 302 and slides along the inclined surface 302, so as to push the movable clamping jaw 30 to move away from another clamping jaw 30 in the left-right direction (in this embodiment, the pair of clamping jaws 30 both move back to back), so that the pair of clamping jaws 30 is changed from the clamping state to the releasing state.

In this embodiment, at least one of the pair of jaws 30 facing the other jaw 30 is provided with a bevel 302, the bevel 302 is opposite to the other jaw 30 to form a V-shaped groove, and the opposite surfaces of the two jaws 30 are provided with the bevels 302, so that the two jaws 30 form a V-shaped groove between them, wherein the distance between the two jaws is gradually increased from front to back, i.e. the larger opening of the V-shaped groove faces the rod 22. The V-shaped groove takes the inclined plane 302 as a groove wall; the front end 222 of the rod 22 forms two pushing inclined planes 201, one pushing inclined plane 201 abuts against the inclined plane 302 of one of the adjacent clamping jaws 30 and has a corresponding inclination angle, and the other pushing inclined plane 201 abuts against the inclined plane 302 of the other clamping jaw 30 and has a corresponding inclination angle. Thus, when the operating portion 21 is triggered by the user to drive the rod 22 to move forward, the front end 222 of the rod 22 goes forward and enters into the V-shaped groove, and the two pushing inclined planes 201 abut against the inclined plane 302 to drive the pair of jaws 30 to move away from each other to change to the release state, as shown in fig. 5a to the state shown in fig. 5 b. Of course, in the present application, the wedge-shaped engagement between the clamping jaw 30 and the front end 222 of the rod 22 is not limited thereto, and for example, in a modified embodiment, only the inclined surface 302 may be provided on the clamping jaw 30 and the abutting inclined surface 201 of the rod 22 is eliminated, or only the abutting inclined surface 201 may be provided on the rod 22 and the inclined surface 302 of the clamping jaw 30 is eliminated, and for example, in a modified embodiment, specific positions of the inclined surface 302 and/or the abutting inclined surface 201 may be changed.

Further, the first elastic mechanism 40 is provided as a spring (hereinafter also referred to as 40 for ease of understanding), and may be embodied in the form of a compression spring between the movable jaw 30 and the inner wall of the outer sleeve 10. For example, in the present embodiment, the springs 40 are disposed on opposite sides of the pair of clamping jaws 30, when the operating portion 21 is triggered by a user to drive the rod 22 to move forward, the front end 222 of the rod 22 drives the pair of clamping jaws 30 to move away from each other, and at this time, the springs 40 are compressed; when the user's touch on the operation portion 21 is lost, the spring 40 pushes the pair of jaws 30 to approach each other by the self-deformation restoration (that is, the state is restored, and the state shown in fig. 5b is changed to the state shown in fig. 5 a). It is understood that in an alternative embodiment, the first elastic mechanism 40 may be changed from the compression spring type to a tension spring type (such as two ends connecting two clamping jaws 30), a torsion spring type or even other elastic bodies (such as elastic sheets) which are not springs.

Referring to fig. 2 and 3, the side of the movable clamping jaw 30 facing away from the other clamping jaw 30 (i.e. the opposite side of the two clamping jaws 30 in this embodiment) has a cavity 301, and one end of the spring 40 is disposed in the cavity 301, and the other end thereof extends outwards out of the cavity 301 and abuts against the inner wall of the outer sleeve 10. Therefore, the spring 40 can be limited conveniently through the arrangement of the concave cavity 301, and the dislocation of the spring 40 is avoided.

Further, the clamping jaw 30 is provided as an antistatic TPU integral piece, comprising a block-shaped connecting portion 31 arranged in the inner cavity 15 of the outer sleeve 10 and a plate-shaped clamping arm 32 extending forward from the connecting portion 31 with a second opening 152. In more detail, the inner cavity 15 includes a first cavity 154 for accommodating the connecting portion 31, and the connecting portion 31 and the first cavity 154 are matched in shape and size in a cross section perpendicular to the left-right direction, so that the connecting portion 31 can move only left and right within the first cavity 154. The connecting portion 31 is substantially rectangular in cross section perpendicular to the left-right direction, correspondingly, the first cavity 154 is also substantially rectangular in cross section perpendicular to the left-right direction, and the front and rear sides of the connecting portion 31 respectively contact the front and rear boundaries of the first cavity 154 to prevent the connecting portion 31 from moving forward and backward; of course, the specific shapes of both are not limited thereto. In addition, in the modified embodiment, the connection between the connection portion 31 and the outer sleeve 10 is not limited thereto, for example, the outer sleeve 10 may be provided with a pivot extending left and right so that the connection portion 31 is movably connected with the outer sleeve 10 by being sleeved on the pivot.

From the assembly structure, the outer tube 10 includes a main tube 11 provided with a first opening 151, a front tube 12 butt-mounted on the front end of the main tube 11, and an end plate 13 mounted on the front end surface of the front tube 12 by screws 14. The first chamber 154 is defined by the front tube 12 and the end plate 13, and is recessed at the front end of the front tube 12, the rear boundary of the first chamber 154 is defined by the front tube 12, and the rear end of the end plate 13 is defined by the front boundary of the first chamber 154. The connecting portion 31 of the jaw 30 and the spring 40 are fitted in the first cavity 154. The end plate 13 is provided with two second openings 152 penetrating through the front and rear end surfaces thereof, and the two holding arms 32 of the pair of holding jaws 30 extend forward from the corresponding second openings 152, respectively. The two second openings 152 are arranged side by side along the left-right direction, and the second openings 152 limit the corresponding clamping arms 32, so that the clamping arms 32 can only slide left and right in the second openings 152. With such a structure, the mounting and dismounting of the clamping jaw 30 and the spring 40 can be facilitated.

Further, the inner cavity 15 further includes a second cavity 153 located at the rear end of the first cavity 154 and communicated with the first cavity 154, the second cavity 153 is formed in the front tube 12 of the outer sleeve 10, and the front end 222 of the rod 22 is inserted into the second cavity 153. The shape and size of the second cavity 153 and the front end 222 of the rod 22 are matched, so that the front end 222 of the rod 22 can only move back and forth along the second cavity 153, thereby limiting the rod 22 to shake or rotate circularly in the direction perpendicular to the front and back directions. The front end 222 of the rod 22 is rectangular in cross section perpendicular to the front-rear direction, and correspondingly, the second cavity 153 is also rectangular in cross section perpendicular to the front-rear direction; of course, the specific shapes of both are not limited thereto.

Further, referring to fig. 2 and 3, the holding fixture 100 further comprises a second resilient mechanism 50, the second resilient mechanism 50 acting between the outer sleeve 10 and the inner core rod 20 and being adapted to reset the actuating rod body 22 backwards when the user actuation of the operating portion 21 is lost.

In the present embodiment, referring to fig. 4, the second elastic mechanism 50 is a cylindrical spring (hereinafter also referred to as 50 for convenience of description) accommodated in the inner cavity 15 of the outer sleeve 10 and sleeved on the outer periphery of the inner core rod 20; the outer sleeve 10 has a boss 111 extending toward the inner cavity 15, the inner core rod 20 has a step surface 210 located in the inner cavity 15 and behind the boss 111, and the front end of the spring 50 abuts against the rear end surface of the boss 111 and the rear end abuts against the step surface 210. When the lever body 22 is moved forward by the operation portion 21, the spring 50 is compressed between the boss 111 and the step surface 210 (i.e., the spring 50 is configured in a compressed spring form); and when the operation part 21 is released, the spring 50 drives the rod body 22 to return backward by pushing the step surface 210 under the self-deformation restoration action. It is understood that, in a variation, the second elastic mechanism 50 may also be changed from the above-mentioned compression spring form to a tension spring form, a torsion spring form, or even another elastic body (such as an elastic sheet) which is not a spring.

Further, the rod body 22 is configured as an integral long straight rod extending back and forth, and divided into a thicker cylindrical middle part 220, a thinner cylindrical rear end part 221 and a rectangular column-shaped front end part 222, the middle part 220 of the rod body 22 is located in front of the boss 111 of the outer sleeve 10, and the rear end part 221 of the rod body 22 passes through the boss 111 of the outer sleeve 10 and extends to the rear of the boss 111; the operation part 21 and the rod body 22 are separately arranged and fixedly connected, the operation part 21 is specifically arranged as a cap structure which is sleeved on the rear end part 221 of the rod body 22, the cap structure is sleeved on the periphery of the rear end part 221 of the rod body 22, the cap top of the cap structure protrudes backwards to form a first opening 151, and the front end surface of the cap edge of the cap structure forms the step surface 210 of the core rod 20; the spring 50 is fitted around the rear end 221 of the lever body 22 and is located between the boss 111 and the operating portion 21.

In addition, when the spring 50 drives the rod 22 to return backward, the return position of the rod 22 is determined by a limiting surface (see reference numeral 1110 in fig. 5 b) provided on the outer sleeve 10 and a limited surface (see reference numeral 202 in fig. 5 b) provided on the inner core rod 20. Specifically, the limiting surface provided on the outer sleeve 10 is formed by the front end surface 1110 of the boss 111; correspondingly, the restrained surface of the core rod 20 is formed by a step interface surface 202 between the middle portion 220 and the rear end portion 221 of the rod body 22, which is located in front of the boss 111. When the spring 50 drives the rod 22 to return backward, the step interface 202 abuts against the front face 1110 of the boss 111 to define a backward return position of the rod 22 (i.e. the backward return movement of the rod 22 is terminated), thereby preventing the rod 22 from being excessively separated from the outer sleeve 10 backward under the action of the spring 50.

In summary, an embodiment has at least the following advantages: by adopting the pen-shaped clamping device 100, a person can manually change the clamping state of the pair of clamping jaws 30 from the clamping state to the loosening state or from the loosening state to the clamping state by holding the outer sleeve 10 and touching the operating part 21 with fingers, and the resetting of the pair of clamping jaws 30 is realized by combining the arrangement of the first elastic mechanism 40, so that the clamping or loosening is realized, the structure is simple, the operation is convenient, and the cost is low; getting of components and parts and in the transportation, can use its centre gripping and unclamping components and parts, avoided artifical direct hand contact components and parts and caused the quality hidden danger of product, in addition, clamping jaw 30 can set up to the TPU body of preventing static, can effectively completely cut off the electrostatic interference between staff and the product.
