They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0020] like Figures 1 to 10 As shown, the punching device provided by this utility model includes a base 11, a support 12, a punching assembly 20, and an adjusting assembly 30. The support 12 is fixed on the base 11, and a carrier tape accommodating space 13 is provided between the base 11 and the support 12. The base 11 is provided with a punch 11a communicating with the carrier tape accommodating space 13. The punching assembly 20 is connected to the support 12 and includes a punch 21 and a pressing member 22. The punch 21 and the pressing member 12 are detachably connected. The punch 21 and the punch 11a are matched in size. The pressing member 22 is used to drive the punch 21 to move in a direction close to or away from the punch 11a so that the punch 21 enters or exits the punch 11a. The adjusting assembly 30 includes an adjusting block 31, which is disposed in the punch 11a and can move within the punch 11a.

[0021] The carrier tape accommodating space 13 is used to hold the carrier tape to be punched. The punching assembly 20 is used to punch holes in the carrier tape. The pressing member 22 drives the punch 21 to move in a direction close to or away from the punch 11a, so that the punch 21 passes through the carrier tape accommodating space 13 and enters or exits the punch 11a, punching holes in the carrier tape located in the carrier tape accommodating space 13 and cutting off the damaged portion. The adjusting block 31 is movably disposed in the punch 11a. By moving the adjusting block 31 within the punch 11a, the size of the punch 11a is adjusted to match the size of the punch 21 and the carrier tape to be punched.

[0022] For carrier tapes of different sizes, a punch 21 and a punch 11a adapted to the carrier tape are required to perform the punching operation. The size of the punch 11a in the existing punching device is not adjustable, which means that the punching device can only be used to punch a specific size of carrier tape.

[0023] Based on this, this application adjusts the size of the punch 11a by moving the adjusting block 31 within the punch 11a to match the width of the carrier tape, and uses a punch 21 adapted to the punch 11a. This allows the punching device to be applied to punching carrier tapes of different widths, improving its versatility. Furthermore, it eliminates the need to customize punching devices for any particular width of carrier tape, reducing the variety of punching device specifications and thus lowering manufacturing, maintenance, and management costs. It also shortens the lead time for new products caused by customized punching devices.

[0024] The base 11 includes a first fixing part 11c and a first connecting part 11d. The first fixing part 11c is used to connect with the support 12. A punch 11a is provided in the first connecting part 11d, and the carrier tape accommodating space 13 is located between the first connecting part 11d and the support 12.

[0025] The first fixing part 11c and the first connecting part 11d are arranged along a first direction. In a specific embodiment, the punch 11a is an elongated hole extending along the first direction, that is, the first direction is the length direction of the punch 11a. The adjustment block 31 moves within the punch 11a along the first direction, that is, it adjusts the length of the punch 11a to match the width of the carrier tape.

[0026] The punch 11a penetrates the first connecting portion 11d along the thickness direction. Thus, when the punch 21 punches the carrier tape located in the carrier tape accommodating space 13, the cut-off portion can fall from the bottom of the punch 11a.

[0027] The base 11 also includes a sliding groove 11b communicating with the punch 11a. The sliding groove 11b extends along a first direction, that is, the sliding groove 11b and the punch 11a extend in the same direction. The sliding groove 11b cooperates with a portion of the structure on the adjusting block 31 to guide and restrict the movement of the adjusting block 31 within the punch 11a along the first direction. Sliding grooves 11b are provided on both sides of the punch 11a to improve the stability of the adjusting block 31's movement within the punch 11a.

[0028] The support 12 includes a second fixing part 12c and a second connecting part 12d. The second fixing part 12c is connected to the first fixing part 11c, and the carrier tape accommodating space 13 is located between the second connecting part 12d and the first connecting part 11d. The base 11 and the support 12 are connected by the first fixing part 11c and the second fixing part 12c. A gap is provided between the first connecting part 11d and the second connecting part 12d to form the carrier tape accommodating space 13.

[0029] A through hole 12a is provided on the support 12, extending through the support 12 along its thickness direction. Specifically, the through hole 12a is provided in the second connecting part 12d, and the through hole 12a and the punch 11a are provided on the same side. The pressing member 22 is movably disposed in the through hole 12a. The pressing member 22 moves along the through hole 12a, thereby driving the punch 21 to move away from or towards the base 11, so that the punch 21 enters or exits the punch 11a.

[0030] The carrier tape accommodating space 13 is located between the second connecting portion 12d and the first connecting portion 11d, thus forming a placement area for placing the carrier tape. The carrier tape accommodating space 13, the punch 11a, and the through hole 12a are arranged on the same side, and the through hole 12a, the carrier tape accommodating space 13, and the punch 11a are connected along the arrangement direction of the base 11 and the support 12. By setting the carrier tape accommodating space 13, the carrier tape is positioned between the second connecting portion 12d and the first connecting portion 11d. When drilling is required, the pressing member 22 drives the punch 21 to move towards the base 11. The punch 21 passes through the carrier tape accommodating space 13 and enters the punch 11a, thereby drilling a hole in the carrier tape and cutting off the damaged portion.

[0031] An opening 13a is provided on the side of the carrier tape accommodating space 13 away from the second fixing part 12c, so as to facilitate placing the carrier tape in the carrier tape accommodating space 13 or removing the carrier tape from the carrier tape accommodating space 13.

[0032] The pressing member 22 includes a main body 22a located within the through hole 12a, a limiting part 22b located on the side of the main body 22a away from the base 11, and an elastic member 22c provided outside the limiting part 22b. The punch 21 is connected to the side of the main body 22a facing the base 11. When the main body 22a is fully inserted into the through hole 12a, the limiting part 22b abuts against the support 12.

[0033] The main body 22a is movably disposed within the through hole 12a. The shape of the main body 22a is the same as that of the through hole 12a. The main body 22a can move along the through hole 12a in a direction away from or towards the base 11, thereby driving the punch 21 to repeatedly perform the punching operation.

[0034] The limiting part 22b is located at the top of the main body 22a. The limiting part 22b is used to abut against the support 12 when the main body 22a is fully inserted into the through hole 12a, meaning the limiting part 22b cannot enter the through hole 12a. Thus, as the main body 22a moves towards the base 11 along the through hole 12a, when the limiting part 22b abuts against the support 12, the main body 22a cannot continue moving towards the base 11 along the through hole 12a, thereby limiting the movement of the main body 22a and restricting the movement distance of the main body 22a and the punch 21. Specifically, the cross-sectional area of ​​the limiting part 22b can be made larger than the cross-sectional area of ​​the through hole 12a.

[0035] An elastic element 22c is disposed on the outside of the limiting part 22b, and is used to reset the pressing part 22. A limiting ring 22b-2 is provided at the top of the limiting part 22b. One end of the elastic element 22c abuts against the support 12, and the other end of the elastic element 22c abuts against the limiting ring 22b-2. The elastic element 22c can be a spring.

[0036] When the pressing member 22 is in an unpressurized state, under the action of the elastic member 22c, the main body 22a extends out from the through hole 12a, and the punch 21 is received in the through hole 12a, so as to place the carrier tape in the carrier tape receiving space 13 or move the carrier tape in the carrier tape receiving space 13. When a downward pressure is applied to the pressing member 22, the main body 22a moves along the through hole 12a towards the side where the base 11 is located, and the punch 21 moves towards the side where the base 11 is located. Until the limiting part 22b abuts against the support 12, the elastic member 22c is compressed by force. At this time, the pressing member 22 can no longer move towards the base 11, and the punch 21 passes through the carrier tape receiving space 13 and enters the punch hole 11a to complete the punching operation of the carrier tape. When the downward pressure on the pressing member 22 is released, under the action of the elastic member 22c, the pressing member 22 moves away from the base 11, the punch 21 is re-accommodated in the through hole 12a, and the pressing member 22 returns to its initial state.

[0037] The pressing component 22 also includes a pressing handle 22d rotatably mounted on the support 12 and a pressing rod 22e connected to the pressing handle 22d. A limiting groove 22b-1 is provided on the limiting part 22b, and the pressing rod 22e is inserted into the limiting groove 22b-1.

[0038] A fixing block 12b is also connected to the support 12, and the pressure handle 22d is rotatably mounted on the fixing block 12b via a pin. When drilling is required, the pressure handle 22d is rotated and pressure is applied to the limiting part 22b through the pressure rod 22e, thereby causing the main body 22a to move along the through hole 12a toward the side where the base 11 is located, and simultaneously driving the punch 21 to move toward the side of the base 11.

[0039] The cooperation of the pressure handle 22d and the pressure rod 22e facilitates the movement of the limiting part 22b and the main body 22a toward the base 11, thereby enabling drilling operations through the punch 21, which is labor-saving and efficient. A limiting groove 22b-1 is provided on the limiting part 22b, and the pressure rod 22e is inserted into the limiting groove 22b-1 to prevent the pressure rod 22e from separating from the limiting part 22b, and to improve the stability of the pressure rod 22e applying pressure to the limiting part 22b and driving its movement.

[0040] The pressure rod 22e has an arc surface 22e-1 that applies pressure to the limiting part 22b. By setting the arc surface 22e-1, it is possible to ensure good contact between the pressure rod 22e and the limiting part 22b during the rotation of the pressure handle 22d, thereby stably driving the limiting part 22b to move towards the side where the base 11 is located.

[0041] The pressure head 21 is detachably mounted to the main body 22a. For carrier belts of different widths, it is necessary to replace the pressure head 21 with one of different sizes accordingly.

[0042] Specifically, the bottom of the main body 22a has a mounting hole, into which the pressure head 21 is inserted and secured with screws. When the pressure head 21 needs to be replaced, simply remove the screws to remove the pressure head 21 from the mounting hole, replace it with a suitable pressure head 21, and retighten the screws. Of course, in other embodiments, the pressure head 21 can also be installed on the main body 22a via a threaded connection, thereby enabling the replacement of the pressure head 21.

[0043] It should be noted that, for ease of replacement of the pressure head 21, in one scenario, the fixing block 12b on the support 12 can be removed, thereby separating the fixing block 12b and the drilling assembly 20 from the support 12, and the drilling assembly 20 can be removed from the through hole 12a for subsequent replacement of the pressure head 21. In another scenario, the pin connecting the pressure handle 22d and the fixing block 12b can be removed, thereby separating the drilling assembly 20 from the support 12, and the drilling assembly 20 can be removed from the through hole 12a for subsequent replacement of the pressure head 21.

[0044] The adjusting block 31 is provided with a sliding rod 31a, which is located within the sliding groove 11a. The sliding rod 31a and the sliding groove 11a work together to guide the movement of the adjusting block 31 within the punch 11a. Alternatively, the adjusting block 31 can be moved along a first direction within the punch 11a by moving the sliding rod 31a. In a specific embodiment, the adjusting block 31 is provided with two sliding rods 31a, thereby improving the stability of the adjusting block 31's movement within the punch 11a.

[0045] The adjustment assembly 30 also includes an adjustment block 32. A connection channel is provided in the base 11, which is connected to the outside of the base. The adjustment component 32 can move within the connection channel. One end of the adjustment component 32 is connected to the adjustment block 31, and the other end of the adjustment component 32 is provided with an operating part 32c.

[0046] Specifically, the connecting channel is disposed in the first fixing part 11c. The connecting channel passes through the first fixing part 11c along the first direction and communicates with the punch 11a, so that one end of the adjusting member 32 is connected to the adjusting block 31. By moving the adjusting member 32 located in the connecting channel, the adjusting block 31 is driven to move along the first direction in the punch 11a.

[0047] On one hand, by moving the adjusting block 31, the carrier tape accommodating space 13 can accommodate carrier tapes of different widths. The adjusting block 31 is moved in a direction away from or towards the opening 13a according to the width of the carrier tape, so that one end of the carrier tape overlaps the adjusting block 31 along its width and the other end overlaps the base 11. On the other hand, by moving the adjusting block 31, the size of the punch 11a along the first direction can be adjusted, thereby adapting the size of the punch 11a along the first direction to the width of the carrier tape and the size of the pressure head 21 along the first direction, so as to facilitate subsequent punching operations.

[0048] Specifically, the adjusting block 31 is driven by the adjusting member 32 to move in the first direction within the punch 11a to a position corresponding to the pressure head 21, so that the side of the adjusting block 31 facing the opening 13a is flush with the side of the pressure head 21 away from the opening 13a.

[0049] The adjusting member 32 has a screw portion 32a and a threaded channel, the screw portion 32a being connected to the threaded channel. It is understood that the screw portion 32a is threadedly connected to the first fixing portion 11c. One end of the screw portion 32a extends into the punch hole 11a and is rotatably connected to the adjusting block 31.

[0050] Rotating the operating part 32c causes the screw part 32a to rotate, moving the screw part 32a along a first direction, which in turn moves the adjusting block 31 within the punch 11a along the first direction. When it is necessary to reduce the size of the punch 11a along the first direction, rotating the screw part 32a moves the adjusting block 31 toward the side where the opening 13a of the carrier tape accommodating space 13 is located. When it is necessary to increase the size of the punch 11a along the first direction, rotating the screw part 32a moves the adjusting block 31 away from the opening 13a.

[0051] The adjusting block 31 is provided with a slot 31b, and the adjusting member 32 also includes a snap-fit ​​part 32b located at one end of the screw part 32a. The snap-fit ​​part 32b snaps into the slot 31b and can rotate within the slot 31b. By providing the snap-fit ​​part 32b and the slot 31b, firstly, the screw part 32a and the adjusting block 31 can be rotatably connected, and secondly, the screw part 32a can drive the adjusting block 31 to reciprocate along the first direction within the punch hole 11a.

[0052] The slot 31b includes a first part and a second part communicating with the first part. The engaging part 32b is circular and located within the first part. The diameter of the engaging part 32b is smaller than the dimension of the first part perpendicular to the first direction, thereby allowing the engaging part 32b to rotate within the first part. The diameter of the engaging part 32b is larger than the dimension of the second part perpendicular to the first direction, thereby limiting and fixing the engaging part 32b within the first part. One end of the screw part 32a passes through the second part and connects to the engaging part 32b.

[0053] The operating part 32c is a non-circular component, which allows the screw part 32a to be rotated by a wrench or the like, thereby driving the adjusting block 31 to move within the punch 11a. In this embodiment, a scale line can be provided within the punch 11a to indicate the moving position of the adjusting block 31, so as to match the width of the carrier tape and the size of the pressure head 21 along the first direction.

[0054] Reference Figure 10 The operating part 32c is connected to a micrometer cylinder 32d, and the screw part 32a is driven to rotate by the micrometer cylinder 32d. The screw part 32a is a micrometer screw. It can be understood that at this time, the screw part 32a, the first fixing part 11c, and the micrometer cylinder 32d form a micrometer head. By rotating the micrometer cylinder 32d, the distance moved by the screw part 32a can be accurately measured, thereby accurately adjusting the movement distance of the adjusting block 31 in the punch 11a to match the width of the carrier belt and the size of the pressure head 21 along the first direction.

[0055] In some embodiments, two adjusting blocks 31 may be movably arranged within the punch 11a. The two adjusting blocks 31 are driven by two adjusting members 32 to move in the first direction within the punch 11a, i.e., two sets of adjusting components 30 are provided.

[0056] In summary, this application adjusts the size of the punch 11a by moving the adjusting block 31, which is movable within the punch 11a, to match the width of the carrier tape. This allows the punching device to be applied to punching carrier tapes of different widths, improving its versatility. Furthermore, it eliminates the need to customize punching devices for any particular width of carrier tape, reducing the variety of punching device specifications and consequently lowering manufacturing, maintenance, and management costs. It also shortens the lead time for new products caused by customized punching devices.

[0057] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0058] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
