Description

Technical Field

[0001] This application relates to the field of material strip cutting technology, and in particular to a material strip cutting device. Background Technology

[0002] ACF (Anisotropic Conductive Film) tape consists of stacked conductive adhesive layers and a carrier film layer. In industrial applications, ACF tape is typically stored and used in rolls. The conductive adhesive layers need to be cut into predetermined lengths using a cutting device. The carrier film layer must not be cut during the cutting of the conductive adhesive layers; therefore, the cutting depth of the ACF tape by the cutting device must be controlled.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] Therefore, it is necessary to provide a strip cutting device to address the problem of controlling the cutting depth of the ACF strip by the cutting device.

[0005] In a first aspect, a strip cutting device includes:

[0006] Support components;

[0007] Z-axis actuator, the Z-axis actuator being disposed on the support assembly;

[0008] A cutting mechanism includes a back blade base, a cutter base, and a cutter. The back blade base is disposed on the support assembly and located at the top of the cutter base along the Z direction. The cutter base is connected to the Z-axis driver. The top surface of the cutter base along the Z direction has a protruding abutment portion. The cutter protrudes from the top surface and is lower than the abutment portion along the Z direction. The Z-axis driver drives the cutter base to move the cutter along the Z direction, so that the abutment portion abuts against the bottom surface of the back blade base. A cutting gap for cutting the material strip is formed between the bottom surface and the cutter. The spacing of the cutting gap along the Z direction is less than the thickness of the material strip.

[0009] In one embodiment, the cutter base includes a first clamping member and a second clamping member. The first clamping member is connected to the Z-axis driver. The cutter is disposed between the first clamping member and the second clamping member. Along the Z-axis, the second clamping member is lower than the cutter. The first clamping member has a protruding abutment portion and a first mounting hole. The second clamping member has a strip-shaped through hole. A first fastener passes through the first mounting hole and the strip-shaped through hole to press the second clamping member against the first clamping member, thereby clamping the cutter.

[0010] In one embodiment, the first clamping member has a first stepped portion, and the second clamping member has a second stepped portion, wherein the first stepped portion can abut against the second stepped portion so that the second clamping member is lower than the cutter along the Z direction.

[0011] In one embodiment, the back knife base includes a back knife support, a back knife adjustment shaft, and a back knife clamping member. The back knife support is connected to the support assembly. Along the Z-direction, the back knife support is located at the top of the back knife clamping member. The back knife adjustment shaft is disposed between the back knife support and the back knife clamping member. The back knife support has a first mounting groove extending through it. The back knife support has two second mounting holes disposed on both sides of the first mounting groove extending through it along the Z-direction. The back knife clamping member has a second mounting groove. The back knife clamping member has two third mounting holes disposed on both sides of the second mounting groove extending through it along the Z-direction. The first mounting groove and the second mounting groove form a back knife shaft hole. The back knife adjustment shaft passes through the back knife shaft hole. A second fastener passes through the second mounting hole and the third mounting hole to fix the back knife support and the back knife clamping member. The bottom surface of the back knife clamping member is used to abut against the abutting part.

[0012] In one embodiment, the Z-axis actuator includes a Z-axis slide cylinder, the movable part of which is connected to the cutter base.

[0013] In one embodiment, the strip cutting device includes a Y-axis driver disposed on the support assembly, the Y-axis driver being driven to connect the Z-axis driver and the cutting mechanism, so that the Z-axis driver and the cutting mechanism move simultaneously in the Y direction.

[0014] In one embodiment, the strip cutting device further includes a connecting plate, the Z-axis driver and the cutting mechanism are both disposed on the connecting plate, and the Y-axis driver is driven and connected to the connecting plate.

[0015] In one embodiment, the Y-axis actuator includes a Y-axis slide cylinder, the movable part of which is connected to the Z-axis actuator and the cutting mechanism.

[0016] In one embodiment, the strip cutting device further includes an X-axis driver that is driven to the support assembly so that the Z-axis driver, the cutting mechanism, and the Y-axis driver all move in the X direction.

[0017] In one embodiment, the X-axis actuator includes a fine-tuning head, an elastic element, an adapter, a fixed element, and a movable element. The fixed element is connected to the support assembly, the movable element is slidably connected to the fixed element, the adapter is connected to the movable element and located on the outside of the fixed element along the X direction, one end of the elastic element along the X direction is connected to the adapter, and the other end is connected to the fixed element, the fine-tuning head is disposed on the adapter, and the head of the fine-tuning head can extend or retract along the X direction.

[0018] In the aforementioned strip cutting device, the strip is placed on the cutter, and the Z-axis driver drives the cutter base to move along the Z-axis, causing the abutment part to abut against the bottom surface of the back blade base. The abutment part restricts the maximum displacement of the cutter in the Z-axis. The strip is positioned in a cutting gap between the bottom surface and the cutter. Since the spacing of the cutting gap along the Z-axis is less than the thickness of the strip, when cutting the ACF strip, the cutter can cut into the conductive adhesive layer, but due to the limiting effect of the abutment part, it will not cut through the carrier film layer. This achieves precise control of the cutting depth of the ACF strip, meeting the requirement of cutting only the conductive adhesive layer without cutting through the carrier film layer.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] Please see Figure 1 This application provides a strip cutting device 100. Please refer to [link to relevant documentation]. Figure 2 The strip cutting device 100 includes a support assembly 1, a Z-axis driver 2, a cutting mechanism 3, a Y-axis driver 4, and an X-axis driver 5. (See also...) Figure 7 The tape cutting device 100 can cut the conductive adhesive layer 201 of the ACF tape 200 without cutting the carrier film layer 202, and can control the cutting depth of the cutter 33.

[0035] Please see Figure 2 In some embodiments, the Z-axis actuator 2 is mounted on the support assembly 1. See also... Figure 3 and Figure 4 The cutting mechanism 3 includes a back blade base 31, a cutter base 32, and a cutter 33 (see [link]). Figure 4 Please see Figure 3 The back blade base 31 is mounted on the support assembly 1 and located at the top of the cutter base 32 along the Z direction. Please refer to [link / reference]. Figure 3 and Figure 2 The cutter base 32 is connected to the Z-axis driver 2. Please refer to [link / reference]. Figure 3 The cutter base 32 has a protruding abutment portion 321 on its top surface along the Z direction. Please refer to [link / reference]. Figure 4 The cutter 33 protrudes from the top surface and is lower than the contact portion 321 along the Z direction. The Z-axis driver 2 drives the cutter base 32 to move the cutter 33 along the Z direction, so that the contact portion 321 abuts against the bottom surface of the back blade base 31. Please refer to [link to relevant documentation]. Figure 5 and Figure 6 The bottom surface of the back blade base 31 and the cutter 33 form a cutting gap 322 for the cutting strip 200. The spacing h1 of the cutting gap 322 along the Z direction is less than the thickness H of the strip 200 (see [reference]). Figure 7The Z-axis actuator 2 is mounted on the support assembly 1 and connected to the cutter base 32. Its function is to drive the cutter base 32 to move in the Z direction (perpendicular to the plane of the strip 200). This design allows for precise control of the cutter 33's position in the Z direction. The cutter base 32 has a protruding abutment 321 on its top surface along the Z direction, and the back blade base 31 is located at the top of the cutter base 32 along the Z direction. When the Z-axis actuator 2 drives the cutter base 32 upwards, the abutment 321 abuts against the bottom surface of the back blade base 31, limiting the maximum displacement of the cutter 33 in the Z direction. The cutter 33 protrudes from the top surface of the cutter base 32 and is lower than the abutment 321 along the Z direction. This means that when the cutter 33 moves upwards to cut, its range of motion is limited by the abutment 321. When the abutment 321 abuts against the bottom surface of the back blade base 31, the cutter 33 will not exceed the predetermined cutting depth. Since the spacing of the cutting gap 322 along the Z direction is less than the thickness of the strip 200, when cutting the ACF strip 200, the cutter 33 can cut into the conductive adhesive layer 201, but because of the limiting of the contact part 321, it will not cut the carrier film layer 202, thereby achieving precise control of the cutting depth of the ACF strip 200 and meeting the requirement of cutting only the conductive adhesive layer 201 without cutting the carrier film layer 202.

[0036] Therefore, the cutting gap 322 spacing h1 can be adjusted by controlling the distance between the cutter 33 protruding from the top surface of the cutter base 32, thereby controlling the cutting depth of the strip 200.

[0037] Please see Figure 4In some embodiments, the cutter base 32 includes a first clamping member 323 and a second clamping member 324. The first clamping member 323 is connected to the Z-axis driver 2. The cutter 33 is disposed between the first clamping member 323 and the second clamping member 324. Along the Z-axis, the second clamping member 324 is lower than the cutter 33. The first clamping member 323 has a protruding abutment portion 321 and a first mounting hole 3231. The second clamping member 324 has a strip-shaped through hole 3241. A first fastener passes through the first mounting hole 3231 and the strip-shaped through hole 3241 to press the second clamping member 324 against the first clamping member 323, thereby clamping the cutter 33. The combination of the first clamping member 323 and the second clamping member 324 facilitates the adjustment of the cutter 33 position. When it is necessary to adjust the distance between the cutter 33 protruding from the top surface of the cutter base 32, the position of the second clamping member 324 relative to the first clamping member 323 can be finely adjusted by using the first fastener passing through the first mounting hole 3231 and the strip-shaped through hole 3241. This fine-tuning method can precisely change the position of the cutter 33 in the Z direction, thereby accurately controlling the spacing and cutting depth of the cutting gap 322. For example, after loosening the first fastener, by moving the second clamping member 324 to connect different positions of the strip-shaped through hole 3241 with the first mounting hole 3231, and then fixing the first fastener, the cutter 33 can be raised or lowered slightly in the Z direction, thereby changing the cutting depth to adapt to ACF strips 200 with different thickness requirements.

[0038] It should be noted that: Please refer to Figure 8 A custom-designed cutting tool adjustment fixture 300 is used to adjust the cutting depth as needed. A boss 301 protrudes from the center of the bottom surface of this fixture 300, with the boss 301 protruding a distance of h1. (See also...) Figure 9 When adjusting the installation position of the cutter 33, the portions on both sides of the boss 301 of the cutter adjusting fixture 300 abut against the abutment portion 321 of the first clamping member 323, so that the boss 301 faces the installation position of the cutter 33, and the top of the cutter 33 abuts against the boss 301. Then, the second clamping member 324 is fixed to the first clamping member 323 by the first fastener, completing the installation of the cutter 33. At this time, the distance between the top of the cutter 33 and the top of the abutment portion 321 of the first clamping member 323 is also h1. Please refer to [link / reference]. Figure 5 and Figure 6 During the cutting process of the strip cutting device 100, the abutting portion 321 of the first clamping member 323 abuts against the bottom surface of the back blade base 31. At this time, the distance between the bottom surface of the back blade base 31 and the top tip of the cutter 33 is also h1. It is understood that... (Please refer to...) Figure 7 h1 is the remaining thickness of the ACF strip 200 after the cutter 33 cuts into it, and the thickness of the strip 200 is H. It can be deduced that the cutting distance of the strip 200 is h2 = H - h1.

[0039] In an optional implementation, the first fastener may be a screw, bolt, or nut.

[0040] Please see Figure 4 In some embodiments, the first clamping member 323 has a first step portion 3232, and the second clamping member 324 has a second step portion 3242. The first step portion 3232 can abut against the second step portion 3242 so that the second clamping member 324 is lower than the cutter 33 in the Z direction. The abutting structure of the first step portion 3232 and the second step portion 3242 can accurately determine the position of the cutter 33 in the Z direction. When the first step portion 3232 abuts against the second step portion 3242, it provides a limit for the position of the second clamping member 324 in the Z direction, ensuring that the second clamping member 324 is always lower than the cutter 33 in the Z direction.

[0041] Please see Figure 3 and Figure 2 In some embodiments, the cutter base 32 further includes a cutter support 325, one end of which is connected to the output end of the Z-axis driver 2, and the other end of which is connected to the first clamping member 323. Providing the cutter support 325 increases the connection area between the first clamping member 323 and the Z-axis driver 2, thereby improving connection stability.

[0042] Please see Figure 10In some embodiments, the back knife base 31 includes a back knife support 311, a back knife adjustment shaft 312, and a back knife clamping member 313. The back knife support 311 is connected to the support assembly 1. Along the Z-direction, the back knife support 311 is located at the top of the back knife clamping member 313. The back knife adjustment shaft 312 is disposed between the back knife support 311 and the back knife clamping member 313. The back knife support 311 is provided with a first mounting groove 3111, and the back knife support 311 is provided with two second mounting holes 31 respectively disposed on both sides of the first mounting groove 3111 along the Z-direction. 12. The back knife clamping member 313 is provided with a second mounting groove 3131. The back knife clamping member 313 has two third mounting holes 3132 respectively located on both sides of the second mounting groove 3131 along the Z direction. The first mounting groove 3111 and the second mounting groove 3131 form a back knife shaft hole. The back knife adjusting shaft 312 passes through the back knife shaft hole. The second fastener passes through the second mounting hole 3112 and the third mounting hole 3132 to fix the back knife support member 311 and the back knife clamping member 313. The bottom surface of the back knife clamping member 313 is used to abut against the abutment part 321. When the strip cutting device 100 is working, the cutter 33 will apply a force to the back knife base 31. The back knife support member 311 can effectively transfer these forces to the support assembly 1, ensuring that the entire cutting mechanism 3 will not shake or shift due to force during operation, maintaining the stability of the cutting operation, and helping to improve the cutting accuracy. The back knife support 311 and the back knife clamping member 313 are fixed by a second fastener passing through the second mounting hole 3112 and the third mounting hole 3132, so that the two are tightly integrated into a whole structure. This stable connection method can prevent the loosening or separation of the internal components of the back knife base 31 during the cutting process, ensuring the reliability of the overall structure of the back knife base 31, so that it can participate in the cutting work stably for a long time. The back knife adjustment shaft 312 passes through the back knife shaft hole formed by the first mounting groove 3111 and the second mounting groove 3131. By operating the back knife adjustment shaft 312, the horizontal position of the back knife clamping member 313 can be changed, so that the bottom surface of the back knife clamping member 313 is flush with the abutment part 321.

[0043] In an optional implementation, the second fastener may be a screw or bolt in combination with a nut or other fastener.

[0044] Please see Figure 11In optional embodiments, the Z-axis actuator 2 may include a telescopic motor or a telescopic cylinder. In some embodiments, the Z-axis actuator 2 includes a Z-axis slide cylinder, the movable part of which is connected to the cutter base 32. The Z-axis slide cylinder enables precise linear motion. In the Z direction, it can drive the cutter base 32 to move according to a preset stroke and speed, so that the cutter 33 accurately reaches the required position, thereby ensuring precise control of the cutting gap 322. The slide cylinder has high motion smoothness and will not experience violent shaking or deviation during movement, thus maintaining the stability of the cutter base 32 and the cutter 33.

[0045] Please see Figure 11 In an optional embodiment, the movable part of the Z-axis driver 2 is connected to the cutter support 325.

[0046] Please see Figure 11 In some embodiments, the strip cutting device 100 includes a Y-axis driver 4, which is mounted on the support assembly 1. The Y-axis driver 4 is connected to the Z-axis driver 2 and the cutting mechanism 3, so that the Z-axis driver 2 and the cutting mechanism 3 move simultaneously along the Y direction. With the addition of the Y-axis driver 4, the strip cutting device 100 can move in the Y direction. For the ACF strip 200 with a large width, the cutting blade 33 can move along the width direction (Y direction) of the strip 200 by the drive of the Y-axis driver 4, thereby realizing the cutting of the strip 200 at different positions without the need for manual adjustment of the position of the strip 200, which greatly improves the cutting efficiency.

[0047] In optional embodiments, the Y-axis actuator 4 may include a telescopic motor or a telescopic cylinder. In some embodiments, the Y-axis actuator 4 includes a Y-axis slide cylinder, the movable part of which is connected to the Z-axis actuator 2 and the cutting mechanism 3. The Y-axis slide cylinder enables precise linear motion. In the Y direction, it can drive the cutter base 32 to move according to a preset stroke and speed, so that the cutter 33 accurately reaches the required position, thereby ensuring precise control of the cutting gap 322. The Y-axis slide cylinder has high motion smoothness, and there will be no violent shaking or deviation during the movement, which can maintain the stability of the cutter base 32 and the cutter 33.

[0048] Please see Figure 11In some embodiments, the strip cutting device 100 further includes a connecting plate 41, on which the Z-axis driver 2 and the cutting mechanism 3 are both mounted, and the Y-axis driver 4 is driven and connected to the connecting plate 41. The connecting plate 41 integrates the Z-axis driver 2 and the cutting mechanism 3, making the device structure more compact, reducing the dispersion of components, and avoiding problems such as complex connections and excessive space occupation that may result from component dispersion. By fixing the Z-axis driver and the cutting mechanism 3 to the connecting plate 41, their relative positions are more stable. During the cutting process, the movement of the Z-axis driver 2 and the operation of the cutting mechanism 3 will generate certain vibrations and forces. The connecting plate 41 can act as a rigid connecting carrier, effectively dispersing and absorbing these forces, preventing relative displacement or loosening between the Z-axis driver 2 and the cutting mechanism 3 due to force, and maintaining the accuracy and reliability of the cutting device.

[0049] In an optional embodiment, the movable part of the Y-axis sliding cylinder is connected to the connecting plate 41.

[0050] Please see Figure 11 In some embodiments, the strip cutting device 100 further includes an X-axis driver 5, which is driven and connected to the support assembly 1 so that the Z-axis driver 2, the cutting mechanism 3, and the Y-axis driver 4 all move along the X-direction. The X-axis driver 5 enables automatic movement and positioning of the strip 200 in the X-direction (typically the conveying direction of the strip 200). During batch cutting, the strip 200 can be quickly moved to the next cutting position without requiring manual adjustment of the strip 200.

[0051] Please see Figure 11 In some embodiments, the X-axis actuator 5 includes a fine-tuning head 51, an elastic element 52, an adapter 53, a fixing element 54, and a movable element 55. See [link to relevant documentation]. Figure 12The fixed member 54 is connected to the support assembly 1, the movable member 55 is slidably connected to the fixed member 54, the adapter 53 is connected to the movable member 55 and is located on the outside of the fixed member 54 in the X direction, one end of the elastic member 52 in the X direction is connected to the adapter 53, and the other end is connected to the fixed member 54, and the adjusting head 51 is provided on the adapter 53, the head of the adjusting head 51 can extend or retract in the X direction. It can be understood that when the head of the adjusting head 51 extends relative to the movable member 55 in the X direction, it pushes the fixed member 54 to move in the X direction, thereby causing the support assembly 1 to move in the X direction. The support assembly 1 drives the Z-axis driver 2, the cutting mechanism 3 and the Y-axis driver 4 to move in the X direction, at which time the elastic member 52 extends. When the head of the adjusting head 51 retracts relative to the movable part 55 in the X direction, the elastic part 52 contracts and resets, and the fixed part 54 returns to its original position in the X direction under the pull of the elastic part 52. This causes the support to drive the Z-axis driver 2, the cutting mechanism 3 and the Y-axis driver 4 to move in the opposite direction in the X direction, thus adjusting the position of the Z-axis driver 2, the cutting mechanism 3 and the Y-axis driver 4 in the X direction.

[0052] It should be noted that the fine adjustment head 51 is commercially available and is a conventional component known to those skilled in the art; therefore, its structure will not be described in detail here.

[0053] In an optional embodiment, the fixed member 54 may be a slide rail, and the movable member 55 may be a slider, with the slider slidably connected to the slide rail. Alternatively, the fixed member 54 may be a sleeve, and the movable member 55 may be an inner cylinder, with the sleeve slidably connected to the inner cylinder.

[0054] In an optional embodiment, the elastic element 52 may be a spring or a sheet, etc.

[0055] Please see Figure 11 In an optional embodiment, the support assembly 1 includes a first mounting side plate 11, a second mounting side plate 12, a third mounting side plate 13, and a fourth mounting side plate 14 connected to each other. The first mounting side plate 11 is arranged along the Y and Z directions and is connected to the Y-axis driver 4. The second mounting side plate 12 is arranged along the Z and X directions and is connected to the X-axis driver 5. The third mounting side plate 13 is located between the second mounting side plate 12 and the first mounting side plate 11, and is connected at the corner of the first mounting side plate 11 and the second mounting side plate 12 to improve the connection stability between the second mounting side plate 12 and the first mounting side plate 11. The third mounting side plate 13 is arranged along the X and Y directions and is located at the bottom of the second mounting side plate 12 to support the X-axis driver 5.
