Description

Technical Field

[0001] This utility model relates to the field of marking machine technology, and in particular to a laser marking machine. Background Technology

[0002] Laser marking machines use laser beams to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, or by using light energy to cause chemical and physical changes in the surface material to "etch" a mark, or by using light energy to burn away part of the material to reveal the desired pattern or text. It is mainly used in electronic components, electrical appliances, mobile communications, hardware products, precision instruments, automotive parts, and so on.

[0003] Currently, in the production process of automotive charging ports, various assembly operations are required. After assembly, marking is necessary, necessitating the use of laser marking machines. However, current marking machines typically utilize fixed positioning fixtures to position the assembly. When assemblies of the same size are positioned, the marking machine can mark the same location. However, when marking assemblies of different sizes, the fixed positioning fixtures are difficult to adjust, resulting in marking positions that are not aligned, thus reducing production quality and indicating room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laser marking machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laser marking machine includes a worktable, with support feet fixedly connected to the four corners of the lower surface of the worktable. A support frame is fixedly connected to the upper surface of the worktable, and a lighting lamp is fixedly connected to the lower surface of the support frame. A Standard Operating Procedure (SOP) signboard is fixedly connected to the inner wall of the front of the support frame. A marking assembly and a feeding assembly are fixedly connected to the upper surface of the worktable. The marking assembly includes a positioning frame, a hand-cranked column fixedly connected to the upper surface of the positioning frame, and the marking machine body fixedly connected to the right side of the hand-cranked column. The surface has a sliding groove, and a slider is slidably connected to the inner bottom wall of the sliding groove. A first motor is fixedly connected to the front of the positioning frame, and a lead screw is fixedly connected to the output end of the first motor. A clamping frame is fixedly connected to the upper surface of the slider, and a second motor is fixedly connected to the front of the clamping frame. A bidirectional screw is fixedly connected to the output end of the second motor. A strip groove is formed in the inner bottom wall of the clamping frame, and two movable blocks are slidably connected to the inner bottom wall of the strip groove. A clamping plate is fixedly connected to the upper surface of each of the two movable blocks, and clamping grooves are formed on the opposite sides of the two clamping plates.

[0007] Preferably, the rear end of the lead screw is rotatably connected to the inner rear wall of the positioning frame, and the slider is threadedly connected to the lead screw. The first motor can drive the slider to move back and forth through the lead screw, thereby changing the relative position between the clamping frame and the marking machine body.

[0008] Preferably, the rear end of the bidirectional screw is rotatably connected to the inner rear wall of the strip groove, and the two movable blocks are respectively threaded to the positive and negative threads on the surface of the bidirectional screw. After the second motor drives the bidirectional screw to rotate, the two movable blocks can drive the two clamping plates to move towards the opposite surface.

[0009] Preferably, the feeding assembly includes a conveyor belt, with the left side of the conveyor belt fixedly connected to the right side of the positioning frame.

[0010] Preferably, a collection frame is fixedly connected to the right side of the workbench. The front and back of the collection frame are respectively provided with a first moving groove and a second moving groove. A rectangular block is slidably connected to the inner wall of the first moving groove. A third motor is fixedly connected to the front of the rectangular block. A feeding plate is rotatably connected to the back of the rectangular block. A slot is provided on the upper surface of the feeding plate. A transmission block is slidably connected to the inner wall of the second moving groove. A fourth motor is fixedly connected to the upper surface of the collection frame. A threaded rod is fixedly connected to the output end of the fourth motor. The lower end of the threaded rod is rotatably connected to the inner bottom wall of the second moving groove. The transmission block is threadedly connected to the threaded rod. The fourth motor can drive the threaded rod to rotate, thereby driving the transmission block and the feeding plate to move downward, which facilitates the feeding operation of the parts.

[0011] Preferably, the position of the unloading plate corresponds to the position of the conveyor belt, and the output end of the third motor is fixedly connected to a connecting shaft. The rear end of the connecting shaft passes through the rectangular block and is fixedly connected to the front of the unloading plate. The conveyor belt can transport the marked parts to the top of the unloading plate, and the third motor can drive the unloading plate to rotate through the connecting shaft.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By setting a lead screw, slider, clamping frame, movable block and clamping plate, it is easy to perform positioning operations on the assembly from both the front and rear, ensuring that the marking position of the assembly of the same size is always consistent. When dealing with assembly assemblies of different sizes, the first motor drives the lead screw to rotate, thereby adjusting the relative position of the clamping frame and the marking machine body through the slider, which can ensure that assembly assemblies of different sizes can also be marked to the same position, thereby improving production quality.

[0014] 2. By setting up a conveyor belt and a feeding plate, it is easy to collect and organize the marked assembly, which facilitates subsequent packaging operations. The fourth motor and threaded rod can drive the transmission block and the feeding plate to descend, and the third motor can drive the feeding plate to rotate through the connecting shaft, thereby causing the assembly on the feeding plate to tilt. This will not damage the assembly, but will also complete the automated feeding operation of the assembly, improving production efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1 and Figure 2 A laser marking machine includes a worktable 1, with support feet fixedly connected to the four corners of the lower surface of the worktable 1, a support frame 2 fixedly connected to the upper surface of the worktable 1, a lighting lamp 3 fixedly connected to the lower surface of the support frame 2, an SOP signboard 4 fixedly connected to the inner wall of the front of the support frame 2, a marking component fixedly connected to the upper surface of the worktable 1, and a feeding component fixedly connected to the upper surface of the worktable 1. The marking component includes a positioning frame 5, a hand-cranked column 6 fixedly connected to the upper surface of the positioning frame 5, and a marking machine body 7 fixedly connected to the right side of the hand-cranked column 6.

[0021] The upper surface of the positioning frame 5 is provided with a sliding groove, and the inner bottom wall of the sliding groove is slidably connected to a slider 8. The front of the positioning frame 5 is fixedly connected to a first motor 9, and the output end of the first motor 9 is fixedly connected to a lead screw 10. The rear end of the lead screw 10 is rotatably connected to the inner rear wall of the positioning frame 5, and the slider 8 is threadedly connected to the lead screw 10. The upper surface of the slider 8 is fixedly connected to a clamping frame 11, and the front of the clamping frame 11 is fixedly connected to a second motor 12. The output end of the second motor 12 is fixedly connected to a bidirectional screw 13.

[0022] The inner bottom wall of the clamping frame 11 is provided with a strip groove. Two movable blocks 14 are slidably connected to the inner bottom wall of the strip groove. The rear end of the bidirectional screw 13 is rotatably connected to the inner rear wall of the strip groove. The two movable blocks 14 are respectively threaded to the positive and negative threads on the surface of the bidirectional screw 13. The upper surfaces of the two movable blocks 14 are fixedly connected with clamping plates 15. The opposite surfaces of the two clamping plates 15 are provided with clamping grooves.

[0023] After the second motor 12 starts, it can drive the two movable blocks 14 to move towards the opposite face through the bidirectional screw 13, thereby driving the two clamping plates 15 to move closer to the center until the front and rear surfaces of the assembly are pressed together. Since the two clamping plates 15 move towards the center synchronously, the clamping position of the assembly of the same size remains fixed, thus ensuring that the marking position is consistent. For assembly assemblies of different sizes, the first motor 9 drives the lead screw 10 to rotate, thereby driving the clamping frame 11 to move back and forth through the slider 8, which can complete the clamping position adjustment of assembly assemblies of different sizes, ensuring that the marking position of each assembly is consistent and improving production quality.

[0024] Example 2: Refer to Figure 1 and Figure 3 The unloading assembly includes a conveyor belt 16, the left side of which is fixedly connected to the right side of the positioning frame 5. A collection frame 17 is fixedly connected to the right side of the workbench 1. A first moving groove and a second moving groove are respectively opened on the front and back of the collection frame 17. A rectangular block 18 is slidably connected to the inner wall of the first moving groove. A third motor 19 is fixedly connected to the front of the rectangular block 18. A unloading plate 20 is rotatably connected to the back of the rectangular block 18. A slot is opened on the upper surface of the unloading plate 20.

[0025] The inner wall of the second moving trough is slidably connected to a transmission block 21, the upper surface of the collection frame 17 is fixedly connected to a fourth motor 22, the output end of the fourth motor 22 is fixedly connected to a threaded rod 23, the lower end of the threaded rod 23 is rotatably connected to the inner bottom wall of the second moving trough, and the transmission block 21 is threadedly connected to the threaded rod 23. The position of the unloading plate 20 corresponds to the position of the conveyor belt 16, and the output end of the third motor 19 is fixedly connected to a connecting shaft 24. The rear end of the connecting shaft 24 passes through the rectangular block 18 and is fixedly connected to the front side of the unloading plate 20.

[0026] The conveyor belt 16 can transport the assembly to the top of the unloading plate 20. The slot prevents the assembly from falling off. After the fourth motor 22 starts, it can drive the transmission block 21 to descend through the threaded rod 23, thereby moving the unloading plate 20 to the bottom position of the collection frame 17. At this time, the third motor 19 starts and drives the unloading plate 20 to rotate and tilt through the connecting shaft 24 until the assembly is tilted into the collection frame 17, completing the automated unloading operation and improving production efficiency.

[0027] Working principle: First, the operator places the assembly to be marked into the clamping frame 11. The second motor 12 is then turned on, causing the two movable blocks 14 to move towards their opposite faces until the two clamping plates 15 press against the front and rear surfaces of the assembly. Because the two clamping plates 15 move towards their opposite faces at a uniform speed, the marking position of assemblies of the same size placed in the clamping frame 11 remains consistent. When the size of the assembly changes, the first motor 9 starts and drives the lead screw 10 to rotate, which in turn drives the clamping frame 11 to move back and forth via the slider 8. This allows the marking position of the assembly to be adjusted according to different assemblies of different sizes. Ensuring that the marking position of each assembly is in the same location greatly improves production quality. After marking, the assembly is placed on the conveyor belt 16, which transports it to the unloading plate 20. At this time, the fourth motor 22 starts and drives the threaded rod 23 to rotate, which in turn drives the unloading plate 20 to descend through the transmission block 21. When the unloading plate 20 moves the assembly to the bottom of the collection frame 17, the third motor 19 drives the unloading plate 20 to rotate through the connecting shaft 24, thereby tilting the assembly into the collection frame 17, completing the automated unloading operation of the assembly and improving production efficiency.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
