Figure 1 The Y-direction (i.e., the left-right direction of base 1) in this application, and the third direction mentioned in this application are... Figure 1 The Z-direction (that is, the up and down direction of base 1).

[0021] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a marking device, including a base 1, a platform 2, a support frame 3, a guide rod 31, a slide 32, a tool holder 4, and a tool assembly 5; The platform 2 is slidably mounted on the base 1 along the first direction, the support frame 3 is mounted on the base 1, and the guide rod 31 is mounted on the support frame 3 along the second direction; The slide block 32 is provided with a sliding hole, and the slide block 32 is slidably mounted on the guide rod 31 through the sliding hole; the knife holder 4 is movably mounted on the slide block 32 along a third direction; the first direction, the second direction, and the third direction are perpendicular to each other; The cutting tool assembly 5 is mounted on the cutting tool holder 4 and is used to scribing the workpiece 100 to be scribed on the stage 2.

[0022] The platform 2 can be slidably mounted on the top surface of the base 1 via a guide rod sliding sleeve assembly, a guide rail slider assembly, a lead screw nut assembly, a linear motor, a pneumatic cylinder, a hydraulic cylinder, etc.; the part to be scribed 100 includes, but is not limited to, glass, thin films of solar cells, etc. The support frame 3 is mounted on the top surface of the base 1 and extends upwards. A sliding sleeve, bearing, etc. can be installed in the sliding hole, so that the slide block 32 can be slidably mounted on the guide rod 31 via the sliding sleeve, bearing, etc.

[0023] Specifically, the workpiece 100 to be scribed is placed on the stage 2. The tool holder 4 slides along a third direction on the slide 32 to adjust the height of the tool assembly 5. After the tool assembly 5 is adjusted to the required height, it drives the slide 32 to slide along a second direction on the guide rod 31. The tool assembly 5 then scribes lines on the workpiece 100 along the second direction. The stage 2 moves along the first direction on the base 1 to adjust the scribing position of the workpiece 100. Then, it drives the slide 32 to slide along the guide rod 31 along the second direction, and the tool assembly 5 scribes lines on the workpiece 100 again along the second direction. This allows for spaced scribing along the first direction on the workpiece 100. This scribing device uses the tool assembly 5 for scribing, and the workpiece 100 will not have edge quality problems due to thermal effects. Furthermore, the scribing device has a simple structure, low equipment cost, and is convenient to maintain and debug.

[0024] In one embodiment, such as Figures 1 to 3 As shown, the marking device also includes a knob 33, a guide rail 34, and a slider 35. The guide rail 34 is mounted on the slide block 32 along the third direction, and the slider 35 is mounted on the tool holder 4 and slidably connected to the guide rail 34. The knob 33 is provided with a first external thread (not shown in the figure), the slide 32 is provided with a first through hole, and the tool holder 4 is provided with a first internal thread hole (not shown in the figure); one end of the knob 33 passes through the first through hole and is inserted into the first internal thread hole, and the first external thread and the first internal thread hole are threadedly connected.

[0025] The tool holder 4 is slidably mounted on the guide rail 34 via the slider 35, and the end of the knob 33 away from the first external thread is located above the slider 32.

[0026] Specifically, the operator rotates the knob 33, which causes the tool holder 4 to slide in a third direction, thereby adjusting the height of the tool assembly 5 and thus the scribing depth of the tool assembly 5. In this embodiment, the adjustment operation of the scribing device is convenient.

[0027] In one embodiment, such as Figure 3 As shown, the marking device further includes a first elastic element 36, which is arranged along the third direction; one end of the first elastic element 36 abuts against the slide block 32, and the other end of the first elastic element 36 abuts against the end of the blade holder 4 away from the knob 33.

[0028] The first elastic element 36 includes, but is not limited to, springs, leaf springs, etc. The top of the first elastic element 36 abuts against the bottom of the knife holder 4, and the bottom of the first elastic element 36 abuts against the slide block 32.

[0029] In this embodiment, the design of the first elastic element 36 ensures that the tool holder 4 remains stably connected to the slide block 32, thereby guaranteeing the stability of the knob 33 in adjusting the height of the tool holder 4.

[0030] In one embodiment, such as Figure 3 As shown, the slide block 32 is also provided with a scale line 321, and the marking device also includes an indicator 41 installed on the tool holder 4, the indicator 41 being arranged opposite to the scale line 321.

[0031] The scale line 321 is arranged along a third direction, and the indicator 41 extends toward the scale line 321.

[0032] Specifically, as the knob 33 drives the tool holder 4 to move in a third direction, the indicator 41 can indicate different positions on the scale line 321. The operator can obtain the height position of the tool assembly 5 through the indicator 41 and the scale line 321.

[0033] In one embodiment, such as Figures 1 to 5 As shown, the tool assembly 5 includes a lifting member 51, a tool shaft 52, and a slicing blade 53 detachably mounted on the tool holder 4; The tool holder 4 is provided with a second through hole extending along the third direction, and the tool shaft 52 is slidably installed in the second through hole; The lifting member 51 is rotatably mounted on the end of the cutter shaft 52 away from the slicing blade 53 and abuts against the cutter holder 4, and is used to drive the cutter shaft 52 to slide in the second through hole.

[0034] Understandably, the lifting component 51 includes, but is not limited to, a wrench, a screwdriver, etc. The lifting component 51 is rotatably mounted on the upper end of the blade shaft 52, and the slicing blade 53 is mounted on the lower end of the blade shaft 52.

[0035] Specifically, the operator can move the blade shaft 52 and the scribing blade 53 upward by using the lifting component 51. The scribing blade 53 can move away from the platform 2 and the workpiece 100 to be scribed on it. After the position of the platform 2 along the first direction is adjusted, the operator can then move the blade shaft 52 and the scribing blade 53 downward by using the lifting component 51. The scribing blade 53 can then complete the scribing action on the workpiece 100 to be scribed.

[0036] In this embodiment, the marking device is easy to operate.

[0037] In one embodiment, such as Figures 3 to 5As shown, the tool assembly 5 also includes a second elastic element 54 and a rotating cylinder 55 with a second internal thread hole (not shown in the figure), and the tool shaft 52 is provided with a second external thread (not shown in the figure).

[0038] The rotating cylinder 55 includes, but is not limited to, nuts, etc., and the second elastic element 54 includes, but is not limited to, springs, etc.

[0039] In this embodiment, the design of the second elastic element 54 ensures that during the scribing process of the scribing blade 53 on the workpiece 100, the scribing blade 53 and the workpiece 100 are in elastic contact. This avoids damage to the workpiece 100 due to hard contact, thus ensuring the quality of the workpiece 100. Furthermore, the preload of the second elastic element 54 can be adjusted via the rotating cylinder 55.

[0040] In one embodiment, such as Figure 3 and Figure 4 As shown, the tool holder 4 is also provided with a through groove 42 that connects to the second through hole, and the rotating cylinder 55 and the second elastic member 54 are both located in the through groove 42.

[0041] The through groove 42 extends through the tool holder 4 along the second direction, and the rotating cylinder 55 is located in the through groove 42, thereby facilitating the operator to rotate the rotating cylinder 55.

[0042] In one embodiment, such as Figures 1 to 3 As shown, the slide 32 has a handle 322 at the end away from the knife holder 4.

[0043] In this embodiment, the handle 322 is designed to facilitate the operator to slide the slide block 32 along the second direction.

[0044] In one embodiment, such as Figure 2 As shown, the marking device also includes a crank 11, a lead screw 12, and a nut 13; the lead screw 12 is rotatably mounted on the base 1 along the first direction, and the nut 13 is mounted on the platform 2 and threadedly connected to the lead screw 12. The crank 11 is rotatably mounted on the base 1 and connected to the lead screw 12. The crank 11 is used to drive the lead screw 12 to rotate.

[0046] Specifically, the operator rotates the lead screw 12 via the crank 11, and the lead screw 12 drives the platform 2 to move along the first direction via the screw thread.

[0047] In this embodiment, the adjustment operation of the platform 2 moving along the first direction on the base 1 is convenient.

[0048] In one embodiment, such as Figure 1 and Figure 2 As shown, the marking device also includes a limiting member 6 that is magnetically and detachably mounted on the platform 2. The limiting member 6 is used to limit the part 100 to be marked on the platform 2.

[0049] The platform 2 is made of iron, and the limiting member 6 is a magnetic suction member.

[0050] In this embodiment, the limiting member is installed on the platform by magnetic attraction, and the limiting member can limit the part to be marked on the platform, thus making it convenient to install the part to be marked on the platform.
