The purpose of providing the following specific embodiments is to facilitate a clearer and more thorough understanding of the disclosure of this utility model, wherein terms indicating direction such as up, down, left, and right refer only to the position of the illustrated structure in the corresponding drawings. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set on" should be interpreted broadly.

[0029] The following description describes preferred embodiments of the present invention; however, the foregoing description is intended to illustrate the general principles of the present invention and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined by the appended claims.

[0030] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the edge-cutting device 100 provided in this embodiment of the utility model; Figure 2 yes Figure 1A cross-sectional view of a partial structure of a trimming device 100. This embodiment of the present invention provides a trimming device 100. The trimming device 100 includes a support base 110, a first trimming mechanism 120, and a second trimming mechanism 130. The first trimming mechanism 120 and the second trimming mechanism 130 are disposed opposite to each other and slidably mounted on the support base 110. Each of the first trimming mechanism 120 and the second trimming mechanism 130 includes a blade holder 30, a first blade assembly 40, and a second blade assembly 50. The first blade assembly 40 includes a first blade holder 41 mounted on the blade holder 30 and a first blade 42 disposed on the first blade holder 41. The second blade assembly 50 is arranged along a first direction X with the first blade assembly 40. The second blade assembly 50 includes a second blade holder 51, a second blade 52, and an adjusting seat 53. The second blade holder 51 is mounted on the blade holder 30, and the second blade 52 is disposed on the adjusting seat 53. The adjusting seat 53 is movable relative to the second cutter holder 51 in the second direction Y, so that the second blade 52 abuts against the first blade 42 in the second direction Y.

[0031] The edge trimming device 100 provided in this embodiment of the present invention is based on an adjustment seat 53 that is movable relative to the second blade holder 51 in the second direction Y of the edge trimming device 100, and a second blade 52 is disposed on the adjustment seat 53. This reduces the assembly accuracy requirements of the first blade 42 and the second blade 52, and makes the distance between the first blade 42 and the second blade 52 adjustable. This allows the user to adjust the contact force between the second blade 52 and the first blade 42, improves the edge trimming effect of the edge trimming device 100 on the substrate to be trimmed, and prevents the second blade 52 from deforming, thus extending its service life.

[0032] It should be noted that, Figure 1 The purpose is only to schematically describe the arrangement between the support base 110, the first cutting mechanism 120 and the second cutting mechanism 130, and not to make specific limitations on the connection position, connection relationship and specific structure of each component. Figure 1 The illustration of the edge-cutting device 100 in this embodiment is merely a structural representation and does not constitute a specific limitation on the edge-cutting device 100. In other embodiments of this utility model, the edge-cutting device 100 may include components that are more... Figure 1 The components shown may be more or fewer, or may be combined or different. For example, the edge cutting device 100 may also include, but is not limited to, connecting cables, distance sensors, etc.

[0033] The edge-cutting device 100 is used to cut the substrate to be cut. Exemplarily, in this embodiment, the substrate to be cut can be an electrode sheet. Of course, in some embodiments, the substrate to be cut can also be, but is not limited to, a thin film, a metal sheet, etc. Exemplarily, both the first blade 42 and the second blade 52 are configured as disc cutters. Of course, in other embodiments, the shape of the first blade 42 and the second blade 52 can be set according to actual conditions, and this embodiment of the present invention does not impose specific limitations.

[0034] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 1 For reference, the term "first direction X" refers to the arrangement direction of the first blade assembly 40 and the second blade assembly 50, i.e., the up-down direction (where the positive X-axis is up). The term "second direction Y" refers to the arrangement direction of the first edge-cutting mechanism 120 and the second edge-cutting mechanism 130, i.e., the left-right direction (where the positive Y-axis is right). The first direction X and the second direction Y together constitute two orthogonal directions of the edge-cutting device 100. For ease of description, the up-down and left-right orientations in this utility model are relative positions and do not constitute a limitation. The first direction X and the second direction Y can be customized according to the specific structure of the product and the perspective presented in the accompanying drawings; this utility model does not impose specific limitations.

[0035] For example, in this embodiment, the adjusting seat 53 is screwed to the second cutter holder 51. Specifically, the adjusting seat 53 is rotatable relative to the second cutter holder 51. When the user rotates the adjusting seat 53 forward, the adjusting seat 53 moves the second blade 52 closer to the first blade 42. When the user rotates the adjusting seat 53 in the reverse direction, the adjusting seat 53 moves the second blade 52 away from the first blade 42. Thus, on the one hand, it is convenient for the user to manually adjust the distance between the adjusting seat 53 and the second cutter holder 51, thereby adjusting the distance between the first blade 42 and the second blade 52. On the other hand, the threaded connection facilitates assembly and disassembly, enabling the user to continuously fine-tune the second blade 52, and ensuring that the cutting surface of the second blade 52 smoothly approaches the cutting surface of the first blade 42 during the adjustment of the adjusting seat 53, and enabling precise adjustment of the distance between the adjusting seat 53 and the second cutter holder 51. Of course, in some other embodiments, the adjusting seat 53 and the second cutter holder 51 can also be slidably connected, and the distance between the adjusting seat 53 and the second cutter holder 51 is adjusted to a preset distance and then fixed by a locking structure.

[0036] In this embodiment, the adjusting seat 53 includes a first seat 531, a second seat 532, and an elastic member 533. The first seat 531 is connected to the second seat 532. The second blade 52 is mounted on the first seat 531 and located between the first seat 531 and the second seat 532. The elastic member 533 is disposed between the second blade 52 and the second seat 532. Understandably, when the first blade 42 and the second blade 52 are in contact, further rotation of the adjusting seat 53 increases the contact force between the first blade 42 and the second blade 52, thereby preventing gaps between the first blade 42 and the second blade 52 from affecting the cutting effect on the substrate. Thus, the elastic member 533 provides a buffering force to the second blade 52, preventing damage to either the first blade 42 or the second blade 52 due to excessive contact force, and extending the service life of both blades. The elastic member 533 can be a spring. Specifically, the elastic element 533 is configured as a ring spring. Therefore, on the one hand, the ring spring can uniformly buffer the entire rotation of the second blade 52, thereby reducing the adverse effects of the combined force on the first blade 42 and the second blade 52, and improving the protective effect. On the other hand, during the cutting process, the ring spring can also effectively maintain the position of the plane containing the second blade 52, improving the contact effect between the second blade 52 and the first blade 42. Of course, in some embodiments, the elastic element 533 can also be, but is not limited to, an elastic body.

[0037] In this embodiment, the outer edge of the sidewall of the second base 532 facing the second blade 52 is provided with abutting surface 5321. The abutting surface 5321 is inclined relative to the second direction Y. An elastic member 533 is disposed between the second blade 52 and the abutting surface 5321, thereby providing a larger buffer space between the abutting surface 5321 and the second blade 52 for the deformation of the elastic member 533, improving the buffering effect of the elastic member 533. Thus, on the one hand, the force on the root of the second blade 52 is reduced, extending the service life of the second blade 52; on the other hand, the abutting surface 5321 facilitates the installation of the elastic member 533, and the elastic member 533 can seal the gap between the first base 531 and the second base 532, providing a dustproof effect.

[0038] Please refer to it again. Figure 1 The edge trimming device 100 includes a first driver 45 and a first cutter shaft 46 that is pulverizedly connected to the first driver 45. The first cutter shaft 46 is rotatably mounted on the cutter holder 30 and fixedly connected to the first cutter seat 41. The first driver 45 is used to drive the first cutter shaft 46 to drive the first cutter seat 41 to rotate the first blade 42 mounted on the first cutter seat 41 around the central axis of the first cutter shaft 46, so that the substrate to be cut can be cut under the rotation of the first blade 42, thereby improving the edge trimming effect of the edge trimming device 100.

[0039] Please refer to the following: Figure 1 and Figure 3 , Figure 3 yes Figure 1 A cross-sectional view of the first cutter shaft 46 of the edge trimming device 100. Exemplarily, in this embodiment, the first cutter shaft 46 includes a first shaft segment 461, a second shaft segment 462, and a third shaft segment 463. The second shaft segment 462 is connected between the first shaft segment 461 and the third shaft segment 463. The end of the first shaft segment 461 facing away from the second shaft segment 462 is connected to a first driver 45, and the end of the third shaft segment 463 facing away from the second shaft segment 462 is fixedly connected to a first cutter holder 41. The first shaft segment 461 and the second shaft segment 462 are integrally formed; alternatively, the first shaft segment 461 and the second shaft segment 462 are independently arranged and fixedly connected. A spline shaft 465 is provided on the side of the second shaft segment 462 facing away from the first shaft segment 461. The third shaft segment 463 is provided with a mounting hole 467, and a spline sleeve 468 that mates with the spline shaft 465 is provided in the mounting hole 467. In some embodiments, the spline sleeve 468 can be omitted, i.e., the third shaft segment 463 is provided with a spline hole 466 that mates with the spline shaft 465. Thus, a portion of the power output from the first driver 45 is transmitted to one of the first blade assemblies 40 via the first shaft segment 461, and another portion of the power output from the first driver 45 is transmitted to the other first blade assembly 40 via the engagement of the spline shaft 465 with the spline hole 466 and the spline sleeve 468, thereby achieving synchronous rotation of the two first blade assemblies 40 and improving the cutting effect of the trimming device 100.

[0040] In this embodiment, the first shaft segment 461 and the second shaft segment 462 can be independently arranged and fixedly connected, thereby facilitating the assembly between the first shaft segment 461 and the first tool holder 41 of the first tool assembly 40. Of course, in some embodiments, the first shaft segment 461 and the second shaft segment 462 can also be integrally formed, thereby improving the reliability and stability of the connection between the first shaft segment 461 and the second shaft segment 462.

[0041] Of course, in some other embodiments, a splined shaft 465 is provided on the side of the third shaft segment 463 facing the second shaft segment 462, and the second shaft segment 462 is provided with a splined hole 466 that mates with the splined shaft 465; or, the second shaft segment 462 is provided with a mounting hole 467, and a splined sleeve 468 that mates with the splined shaft 465 is provided in the mounting hole 467.

[0042] In some embodiments, the second shaft segment 462 is provided with a movable hole 469 communicating with the spline hole 466 or the mounting hole 467, and the third shaft segment 463 is movably disposed within the movable hole 469 along the second direction Y; or, the third shaft segment 463 is provided with a movable hole 469 communicating with the spline hole 466 or the mounting hole 467, and the second shaft segment 462 is movably disposed within the movable hole 469 along the second direction Y. Thus, on the one hand, the movable hole 469 enables the two first blade assemblies 40 to move closer or further apart; on the other hand, the movable hole 469 can provide guidance for the relative movement of the two first blade assemblies 40.

[0043] In this embodiment, the first driver 45 and the first cutter shaft 46 are configured as one unit, with the two ends of the first cutter shaft 46 respectively connected to two first cutter holders 41. This achieves, on the one hand, synchronous rotation of the first blades 42 located on both sides of the first cutter shaft 46, improving the cutting effect of the edge-cutting device 100; on the other hand, the two first cutter assemblies 40 share one first driver 45, thereby saving costs and improving the overall compactness of the edge-cutting device 100. Of course, in some embodiments, both the first driver 45 and the first cutter shaft 46 are configured as two units, with the two first cutter shafts 46 respectively connected to two first cutter holders 41 and corresponding one-to-one with the two first drivers 45, and the two first cutter holders 41 are independently configured. Specifically, one first driver 45 can be used to drive one of the first cutter shafts 46 to rotate one of the first cutter assemblies 40, and the other first driver 45 can be used to drive the other first cutter shaft 46 to rotate the other first cutter assembly 40. Therefore, by setting up two first drivers 45 that operate independently of each other, it is convenient to assemble, repair and replace one of the first cutter shafts 46 with the corresponding first tool holder 41 and first driver 45, and to assemble, repair and replace the other of the first cutter shafts 46 with the remaining first tool holders 41 and first drivers 45.

[0044] For example, in this embodiment, the second blade assembly 50 further includes a second driver 55 and a second blade shaft 56. The second blade holder 51 is mounted on the second blade shaft 56. The second driver 55 is used to drive the second blade holder 51 together with the second blade 52 and the adjusting seat 53 to rotate around the central axis of the second blade shaft 56, so that the substrate to be cut can be cut under the rotation of the first blade 42 and the second blade 52, thereby improving the cutting effect of the cutting device 100.

[0045] In this embodiment, for example, the second cutter holder 51 is mounted on the second cutter shaft 56 via a mounting bearing 54. Specifically, the mounting bearing 54 is disposed inside the second cutter holder 51 and sleeved on the outside of the second cutter shaft 56. The mounting bearing 54 can be an angular contact ball bearing. Thus, on the one hand, the second cutter holder 51 is connected to the second cutter shaft 56 via the angular contact ball bearing, thereby enabling the second cutter holder 51, together with the second blade 52 mounted on the second cutter holder 51 and the adjusting seat 53, to adapt to high-speed rotation; on the other hand, the angular contact ball bearing can withstand higher radial and axial loads, thereby improving the stable operation of the second cutter assembly 50; furthermore, the angular contact ball bearing can maintain a stable operating state by automatically adjusting the axial position, thereby improving the cutting effect of the trimming device 100. Of course, in some embodiments, the mounting bearing 54 can also adopt other types of bearings according to the actual situation, and this embodiment of the present invention does not make specific limitations.

[0046] Please refer to the following: Figure 2 and Figure 4 , Figure 4 yes Figure 1 The diagram shows the structure of the second blade assembly 50 and the support plate 61 of the edge trimming device 100. In some embodiments, the edge trimming device 100 further includes the support plate 61 and the connecting bearing 62. The connecting bearing 62 is mounted on the support plate 61 and rotatably connected to the second blade shaft 56. The second blade assembly 50 also includes a mounting base 57 and a plurality of fine-tuning elements 58. The mounting base 57 is connected to the blade holder 30 through the support plate 61. The mounting base 57 and the second blade holder 51 are located at opposite ends of the second blade shaft 56. The plurality of fine-tuning elements 58 are disposed on the ends of the mounting base 57 away from the second blade holder 51 and act on the second blade shaft 56 to cause the second blade shaft 56 to rotate about the axis of the connecting bearing 62. Therefore, the user can change the locking depth of the fine-tuning component 58 relative to the mounting base 57 to adjust the position of the end face of the second blade 52 relative to the end face of the first blade 42 and to adjust the position of the central axis of the second blade shaft 56 relative to the central axis of the first blade shaft 46. Specifically, during the fine-tuning process of the fine-tuning component 58, the end of the second blade shaft 56 facing away from the second blade holder 51 can be connected to the axis of the bearing 62 as a fulcrum and rotate accordingly around the fulcrum, thereby avoiding the problem of excessive runout of the end face of the second blade 52 relative to the first blade 42, better reducing the runout of the end face of the second blade 52 during cutting, and thus improving the cutting effect of the edge trimming device 100.

[0047] It should be noted that the end face runout refers to the axial runout (the difference between the lowest and highest points) of the measured end face when it rotates around the reference axis for one revolution, and this runout must not exceed the specified tolerance value. Furthermore, since the adjustment of the position of the end face of the second blade 52 relative to the end face of the first blade 42 by the fine-tuning component 58 is very small, it will not significantly affect the transmission effect of the following transmission component 59.

[0048] In this embodiment, the connecting bearing 62 can be configured as a deep groove ball bearing. Therefore, on the one hand, the engagement between the inner ring of the deep groove ball bearing and the second cutter shaft 56 can fix the second cutter shaft 56 and reduce its oscillation, thereby improving the stable operation of the second cutter assembly 50 and thus improving the cutting effect of the trimming device 100. On the other hand, the deep groove ball bearing has a high load-bearing capacity and can withstand axial and radial loads, as well as instantaneous impact loads, thereby extending the service life of the connecting bearing 62 and improving the reliability of the connection between the second cutter shaft 56 and the support plate 61. Of course, in some embodiments, the connecting bearing 62 can also use other types of bearings depending on the actual situation; this embodiment of the present invention does not impose specific limitations.

[0049] The side wall of the end of the second cutter shaft 56 facing away from the second cutter holder 51 is provided with multiple abutment surfaces 561. The multiple abutment surfaces 561 are used to abut against the fine-tuning component 58, thereby improving the adjustment accuracy of the fine-tuning component 58 and better suppressing the vibration generated by the second cutter shaft 56 during the rotation of the second cutter holder 51, thus improving the cutting effect of the edge trimming device 100.

[0050] In this embodiment, the mounting base 57 includes a base body 571, a first fine-tuning base 572, and a second fine-tuning base 573. The base body 571 is connected to the support plate 61 and is sleeved on the outside of the second cutter shaft 56. The first fine-tuning base 572 is movably connected to the end of the base body 571 away from the second cutter holder 51. A first fine-tuning hole 5721 is provided on the side wall of the first fine-tuning base 572. The second fine-tuning base 573 is disposed on the base body 571 and is provided with a second fine-tuning hole 5731. A plurality of fine-tuning components 58 include a first fine-tuning structure 581 and a second fine-tuning structure 582. The first fine-tuning structure 581 passes through the first fine-tuning hole 5721 and abuts against the end of the second cutter shaft 56 facing away from the second cutter holder 51. The second fine-tuning structure 582 passes through the second fine-tuning hole 5731 and abuts against the first fine-tuning base 572. The adjustment direction of the first fine-tuning structure 581 is perpendicular to the adjustment direction of the second fine-tuning structure 582. In this embodiment, there are two of each of the first and second fine-tuning structures 581. The two first fine-tuning structures 581 are arranged along the first direction X, and the two second fine-tuning structures 582 are arranged along the third direction Z, which is perpendicular to both the first direction X and the second direction Y. Therefore, the user can adjust the locking depth of the two first fine-tuning structures 581 to make the central axis of the second cutter shaft 56 parallel to the central axis of the first cutter shaft 46. The user can also adjust the locking depth of the two first fine-tuning structures 581 to make the central axis of the first cutter shaft 46 and the central axis of the second cutter shaft 56 coplanar, thereby making the end face of the first blade 42 approximately parallel to the end face of the second blade 52, thus enabling the second blade 52 to make good contact with the first blade 42, improving the cutting effect of the edge-cutting device 100. Of course, in some embodiments, the two first fine-tuning structures 581 are arranged along the third direction Z, and the two second fine-tuning structures 582 can also be arranged along the second direction Y.

[0051] The term "third direction Z" refers to the arrangement direction of the two second fine-tuning structures 582, i.e., the front-back direction (where the positive Z-axis is the rear). The third direction Z, together with the first direction X and the second direction Y, constitutes the three orthogonal directions of the trimming device 100. For ease of description, the front-back orientation in this invention is a relative position and does not constitute a limitation. The first direction X, the second direction Y, and the third direction Z can be customized according to the specific structure of the product and the perspective presented in the accompanying drawings; this invention does not impose specific limitations.

[0052] Specifically, the first fine-tuning seat 572 is provided with a receiving hole 5720. The end of the second cutter shaft 56 facing away from the second cutter holder 51 passes through the receiving hole 5720 and is clearance-fitted with the receiving hole 5720, thereby enabling the first fine-tuning structure 581 to adjust the position of the central axis of the second cutter shaft 56 relative to the central axis of the first cutter shaft 46. The first fine-tuning seat 572 is connected to the seat body 571 by a locking member. The first fine-tuning seat 572 is provided with a limiting hole 5722, through which the locking member passes and locks to the seat body 571. The limiting hole 5722 is configured as an oblong hole and is used to limit the range of movement of the first fine-tuning seat 572 relative to the seat body. The extending direction of the limiting hole 5722 is the same as the adjustment direction of the second fine-tuning structure 582, thereby enabling the second fine-tuning structure 582 to drive the second fine-tuning seat 573, together with the first fine-tuning seat 572 and the first fine-tuning structure 581, to rotate the second cutter shaft 56 around the fulcrum in the adjustment direction of the second fine-tuning structure 582. Specifically, the first fine-tuning seat 572 includes a connecting seat body 5723 and a mounting boss 5724. The connecting seat body 5723 is connected between the seat body 571 and the mounting boss 5724. The connecting seat body 5723 is connected to the seat body 571 by a locking member. The limiting hole 5722 penetrates the connecting seat body 5723. The receiving hole 5720 penetrates the connecting seat body 5723 and the mounting boss 5724.

[0053] In this embodiment, the second cutter assembly 50 further includes a transmission member 59, through which the second cutter shaft 56 is driveably connected to the second driver 55. Specifically, the transmission member 59 includes a first synchronous pulley 591, a second synchronous pulley 592, and a synchronous belt 593. The first synchronous pulley 591 is connected to the cutter holder 30 and is driveably connected to the second driver 55. The second synchronous pulley 592 is connected to the second cutter holder 51 and is drively connected to the first synchronous pulley 591 via the synchronous belt 593. Therefore, this utility model achieves the transmission connection between the second driver 55 and the second cutter holder 51 through the transmission component 59, which has a reasonable structural layout and improves the overall compactness of the edge trimming device 100. On the other hand, the setting of the transmission component 59 enables the second driver 55 to accurately control the rotation of the second cutter holder 51, ensuring the accuracy and stability of the rotation and improving the cutting effect of the edge trimming device 100. Furthermore, the design of the first synchronous pulley 591, the second synchronous pulley 592 and the synchronous belt 593 reduces the direct contact between mechanical parts, reduces wear, thereby reducing the frequency of parts replacement and lowering maintenance costs.

[0054] Of course, in some embodiments, the second blade assembly 50 may not include the transmission component 59, that is, the second blade shaft 56 is directly connected to the second driver 55. Since the second blade assembly 50 does not require an additional transmission component 59, the overall structure of the trimming device 100 is simple and compact, reducing costs. Specifically, the second driver 55 drives the second blade shaft 56 to drive the second blade holder 51, along with the second blade 52 mounted on the second blade holder 51 and the adjusting seat 53, to rotate synchronously. The second driver 55 directly drives the second blade shaft 56 to rotate, and the second blade shaft 56 rotates following the rotation of the second blade shaft 56, thereby realizing the rotation of the first blade 42, and thus realizing the cutting of the substrate to be cut.

[0055] For example, in this embodiment, there are two second drivers 55 and two second cutter shafts 56. The two second cutter shafts 56 are respectively connected to two second cutter holders 51 and are arranged in a one-to-one correspondence with the two second drivers 55. The two second cutter shafts 56 are arranged independently and spaced apart. Specifically, one second driver 55 can be used to drive one of the second cutter shafts 56 to rotate one of the second cutter assemblies 50, and the other second driver 55 can be used to drive another of the second cutter assemblies 50 to rotate another of the first cutter assemblies 40. Therefore, by setting up two independently operating second drivers 55, it is convenient to assemble, repair, and replace one of the second cutter shafts 56 with the corresponding second cutter holder 51 and second driver 55, as well as to assemble, repair, and replace the other second cutter shaft 56 with the remaining second cutter holders 51 and second drivers 55.

[0056] Of course, in some embodiments, the second driver 55 and the second cutter shaft 56 are each configured as one, with two second cutter holders 51 connected to each end of the second cutter shaft 56. This achieves, on the one hand, synchronous rotation of the second blades 52 located on both sides of the second cutter shaft 56, improving the cutting effect of the edge-cutting device 100; on the other hand, the two second cutter assemblies 50 share one second driver 55, thereby saving costs and improving the overall compactness of the edge-cutting device 100. For example, the second cutter shaft 56 includes a power shaft section and a transmission shaft section. The power shaft section is drivenly connected to the second driver 55 and fixedly connected to one of the second cutter holders 51. The transmission shaft section is connected to the power shaft section and fixedly connected to the other second cutter holder 51. One of the transmission shaft section and the power shaft section is provided with a splined shaft, and the other is provided with a splined sleeve or splined sleeve that mates with the splined shaft. The connection method between the transmission shaft section and the power shaft section can be referred to the connection method between the second shaft section 462 and the third shaft section 463 of the first cutter shaft 46, and will not be repeated here.

[0057] Please refer to the following: Figure 1 , Figure 5 and Figure 6 , Figure 5 yes Figure 1 A schematic diagram of the structure of part I of the second blade assembly 50 of the edge-cutting device 100; Figure 6 yes Figure 1 This is a schematic diagram of the structure of part II of the second blade assembly 50 of the edge trimming device 100. In some embodiments, the edge trimming device 100 further includes a support plate 61 and a first adjustment mechanism 63. The support plate 61 is slidably connected to the blade holder 30. The second blade assembly 50 is mounted on the support plate 61. The first adjustment mechanism 63 is used to drive the support plate 61 together with the second blade assembly 50 mounted on the support plate 61 to slide relative to the blade holder 30 along a first direction X, so as to adjust the overlap length D of the first blade 42 and the second blade 52 in the first direction X. Thus, on the one hand, the support plate 61 can integrate the second blade assembly 50 into a whole, thereby facilitating the assembly and disassembly between the second blade assembly 50 and the blade holder 30, allowing the second blade assembly 50 to quickly switch configurations to apply different working states, and the overall structure is compact; on the other hand, the first adjustment mechanism 63 can adjust the overlap length D of the first blade 42 and the second blade 52 in the first direction X, thereby improving the cutting effect of the edge trimming device 100.

[0058] Please refer to the following: Figure 1 , Figure 5 and Figure 7 , Figure 7 yes Figure 1 A schematic diagram of a partial structure of the edge-cutting device 100 is shown below. Exemplarily, in this embodiment, the bottom of the blade holder 30 is provided with a first clearance hole 301 through which the first blade shaft 46 rotatably passes. The top of the blade holder 30 is provided with a second clearance hole 302 through which the mounting base 57 movably passes, thereby enabling the first lifting mechanism to drive the support plate 61 and the second blade assembly 50 mounted on the support plate 61 to slide in the first direction X. In some embodiments, the outer wall of the mounting base 57 is adapted to the second clearance hole 302, so that the second clearance hole 302 can guide the sliding movement of the second blade assembly 50 in the first direction X, improving the stability and reliability of the sliding movement of the second blade assembly 50 in the first direction X, and thus improving the cutting effect of the edge-cutting device 100.

[0059] In some embodiments, the second blade assembly 50 further includes a first display structure 71. The first display structure 71 is disposed on one side of the first adjustment mechanism 63 and is used to display the overlap length D. Thus, the first display structure 71 enables visual adjustment of the overlap length D of the first blade 42 and the second blade 52 in the first direction X, improving work efficiency and adjustment accuracy. The first display structure 71 can be configured as a digital display micrometer. Therefore, the user can set the desired overlap length D through the digital display micrometer, and the overlap length D is displayed on the digital display screen of the micrometer, facilitating the user to adjust the overlap length D of the first blade 42 and the second blade 52 in the first direction X through the first adjustment mechanism 63. Of course, in some embodiments, the first display structure 71 can also be configured as a micrometer.

[0060] Please refer to the following: Figure 1 , Figure 4 and Figure 5 Optionally, in some embodiments, the tool holder 30 is provided with a guide structure 31, and the support plate 61 is provided with a mating structure 64 that slides with the guide structure 31. The sliding direction of the mating structure 64 is parallel to the first direction X. Thus, the first adjustment mechanism 63 drives the first tool assembly 40 to move linearly along the first direction X, improving the reliability and stability of the sliding of the first tool assembly 40 in the first direction X, and also improving the adjustment accuracy of the first adjustment mechanism 63.

[0061] One of the guide structure 31 and the mating structure 64 can be configured as a guide rail, and the other of the guide structure 31 and the mating structure 64 can be configured as a guide block that slides in cooperation with the guide rail. Exemplarily, in this embodiment, the guide structure 31 is fixed to the side wall of the tool holder 30 facing the support plate 61, and the mating structure 64 is disposed on the side wall of the support plate 61 facing the tool holder 30. Specifically, a positioning groove 303 is provided on the side wall of the tool holder 30 facing the support plate 61, and the guide structure 31 is installed in the positioning groove 303. Therefore, the positioning groove 303 enables the tool holder 30 and the guide structure 31 to be positioned and assembled, improving the assembly efficiency and assembly yield between the tool holder 30 and the guide structure 31. Of course, in some embodiments, one of the guide structure 31 and the mating structure 64 can be configured as a raceway, and the other of the guide structure 31 and the mating structure 64 can be configured as a roller that slides in cooperation with the raceway.

[0062] Please refer to the following: Figure 1 , Figure 7 and Figure 8 , Figure 8 yes Figure 7The image shows a partial cross-sectional view of the trimming device 100. In some embodiments, the trimming device 100 further includes a second adjustment mechanism 65, which includes a lead screw 651 and a handwheel 652. The lead screw 651 is rotatably connected to the first trimming mechanism 120 along a first rotation direction and rotatably connected to the second trimming mechanism 130 along a second rotation direction. The first rotation direction is opposite to the second rotation direction; for example, one of the first and second rotation directions is clockwise, and the other is counterclockwise. The handwheel 652 is disposed at one end of the lead screw 651 and is used to drive the lead screw 651 to rotate, thereby causing the first trimming mechanism 120 and the second trimming mechanism 130 to move closer together or further apart. Therefore, on the one hand, since the first blade assembly 40 and the second blade assembly 50 on the same side are fixedly installed on the same blade holder 30, the first blade assembly 40, the second blade assembly 50 and the blade holder 30 on the same side are integrated into a single structure. That is, the first edge cutting mechanism 120 and the second edge cutting mechanism 130 are each independently set and each is a single structure. During the process of adjusting the distance between the two first blades 42 or the two second blades 52 in the second direction Y, the first blade assembly 40 and the second blade assembly 50 of the first edge cutting mechanism 120 and the first blade assembly 40 and the second blade assembly 50 of the second edge cutting mechanism 130 move relative to or towards each other as a whole. This ensures the dimensional adjustment accuracy of the two first blades 42 and the two second blades 52 in the second direction Y, thereby improving the cutting accuracy of the substrate to be edged in the second direction Y. On the other hand, by setting a lead screw drive, the adjustment accuracy and reliability are improved, and the lead screw 651 drive has good impact resistance, extending the service life of the edge cutting equipment 100.

[0063] In this embodiment, two bearing seats 11 are provided on the support base 110. The two ends of the lead screw 651 are rotatably connected to the two bearing seats 11 respectively, thereby improving the smoothness of the rotation of the lead screw 651. The two tool holders 30 are located between the two bearing seats 11, so the two bearing seats 11 can also limit and stop the first edge cutting mechanism 120 and the second edge cutting mechanism 130, preventing the first edge cutting mechanism 120 and the second edge cutting mechanism 130 from detaching from the support base 110, thereby improving the safety of the edge cutting equipment 100.

[0064] In this embodiment, the second adjusting mechanism 65 further includes a first nut 653 and a second nut 654. The first nut 653 is mounted on the first trimming mechanism 120. The second nut 654 is disposed on the second trimming mechanism 130. The first nut 653 and the second nut 654 are screwed to the lead screw 651, and the thread direction of the first nut 653 is opposite to the thread direction of the second nut 654. Thus, the arrangement of the first nut 653 and the second nut 654 simplifies the processing and manufacturing of the first trimming mechanism 120 and the second trimming mechanism 130, and facilitates assembly. Specifically, the first nut 653 is mounted on the bottom of the tool holder 30 of the first trimming mechanism 120, and the second nut 654 is mounted on the bottom of the tool holder 30 of the second trimming mechanism 130. The first nut 653 and the second nut 654 are each embedded in their respective tool holders 30, improving the connection reliability.

[0065] Of course, in some embodiments, the second adjusting mechanism 65 may not include the first nut 653 and the second nut 654. Specifically, the first trimming mechanism 120 is provided with a first threaded hole that is screwed to the lead screw 651, and the second trimming mechanism 130 is provided with a second threaded hole that is screwed to the lead screw 651. The thread direction of the first threaded hole is opposite to the thread direction of the second threaded hole.

[0066] In some embodiments, the trimming device 100 further includes a second display structure 72. The second display structure 72 is disposed on the side of the support base 110 near the handwheel 652 and is used to display the distance between the two second blades 52 in the second direction Y. Thus, the second display structure 72 enables visual adjustment of the distance between the two second blades 52 in the second direction Y, improving work efficiency and adjustment accuracy. The second display structure 72 is mounted on the bearing seat 11. Specifically, the second display structure 72 is mounted on the side wall of the bearing seat 11 facing the handwheel 652, making it convenient for the user to observe the dimensional parameters displayed by the second display structure 72, conforming to the user's through-feeding habits and improving the user experience. The second display structure 72 can be configured as a digital micrometer. Of course, in some embodiments, the second display structure 72 can also be configured as a micrometer.

[0067] In some embodiments, the trimming device 100 further includes a slide rail 12 and a slider 32 cooperating with the slide rail 12. One of the slider 32 and the slide rail 12 is fixed to the support base 110, and the other of the slider 32 and the slide rail 12 is fixed to the blade holder 30. Thus, on the one hand, the second adjustment mechanism 65 drives the first blade assembly 40 and the second blade assembly 50 to move linearly along the second direction Y, improving the reliability and stability of the sliding of the first blade assembly 40 and the second blade assembly 50 in the second direction Y, and improving the adjustment accuracy of the second adjustment mechanism 65; on the other hand, the rotational motion of the blade holder 30 and the lead screw 651 can also be converted into linear motion of the blade holder 30 relative to the support base 110, increasing the stroke of the first trimming mechanism 120 and the second trimming mechanism 130, enabling the trimming device 100 to meet the cutting requirements of substrates of different sizes, providing high flexibility. Specifically, the slide rail 12 is fixed to the surface of the support base 110 facing the blade holder 30, and the slider 32 is disposed on the surface of the blade holder 30 facing the support base 110. Of course, in some embodiments, the slide rail 12 and the slider 32 may also be configured as a raceway and a roller that slides with the raceway.

[0068] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
