Description

Technical Field

[0001] This utility model relates to the field of relay processing, and in particular to a laser marking device for relays. Background Technology

[0002] In the production and manufacturing of electronic components such as relays, clear and durable markings are typically required on the surface of the product casing to achieve product traceability, model identification, and quality control. Laser marking technology, due to its advantages of being non-contact, highly precise, fast, and providing permanent markings, has become the mainstream marking method on relay production lines. Currently, the common process involves placing the relay to be marked on a conveyor device, which automatically transports it to the laser marking machine's workstation via a conveyor belt. After the relay is positioned, the laser head activates to complete the marking operation, and then the relay continues to the next process.

[0003] In existing technologies, to ensure that the relay maintains a stable posture and accurately reaches the marking position during transportation, fixed limiting strips or rods are typically installed on both sides of the conveyor belt to laterally limit the relay and prevent it from shifting during transportation, thereby ensuring the accuracy of the marking position. However, this structure has significant technical drawbacks: due to the diverse range of relay product models, different models vary considerably in size and shape (such as length, width, height, and pin layout), while the limiting strips in traditional devices have fixed positions or limited adjustment ranges, making it impossible to flexibly adapt to the production needs of different product specifications.

[0004] When switching to produce relays of different sizes, operators often need to stop the machine and manually replace the limit rods with different spacings, or even replace the entire conveyor belt, to meet the new positioning requirements. This process is not only time-consuming and labor-intensive, increasing equipment debugging time, but frequent disassembly and assembly can also lead to equipment wear, affecting positioning accuracy and operational stability.

[0005] Therefore, there is an urgent need to design a laser marking device specifically for relays that is easy to adjust and highly compatible. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a laser marking device for relays that is easy to adjust and highly compatible.

[0007] The technical solution is: a laser marking device for relays, including a base, a Z-axis module, a laser, a control panel, a conveyor belt, and an adjustment mechanism. The Z-axis module is located on the top rear side of the base. The laser is mounted on the slider of the Z-axis module via an adapter plate. The control panel is located on the right side of the Z-axis module. The control panel is used to control the marking path. The conveyor belt is installed on the top front side of the base. Adjustment mechanisms are located on the front and rear sides of the conveyor belt. The adjustment mechanisms can limit the conveying of electrical appliances of different sizes.

[0008] Furthermore, the adjustment mechanism includes a bidirectional lead screw, a handwheel, guide rods, and limiting strips. A bidirectional lead screw perpendicular to the conveying direction is horizontally rotatably installed in the middle of the conveyor belt. A handwheel is installed at the front end of the bidirectional lead screw. Guide rods are symmetrically installed on both the front and rear sides of the conveyor belt. Limiting strips are slidably connected between the guide rods on the same side. The limiting strips are threadedly connected to the bidirectional lead screws. The limiting strips extend upward to the top of the conveyor belt, and the bottom of the limiting strips fits against the top of the conveyor belt. By rotating the bidirectional lead screws, the limiting strips can be moved to close or separate.

[0009] Furthermore, the adjustment mechanism also includes a butterfly bolt, which is vertically connected to the front middle of the conveyor belt via threads, with the bottom end of the butterfly bolt pressing against the top of the bidirectional lead screw.

[0010] Furthermore, it also includes a precision positioning mechanism. A precision positioning mechanism is installed on the conveyor belt below the laser. The precision positioning mechanism includes a mounting block, a limit plate, an adjusting nut, a sliding plate, a slide cylinder, a push block, and a spring. A mounting block is installed on the rear side of the conveyor belt below the laser. A limit plate is slidably connected to the upper part of the mounting block. The limit plate is fixed to the mounting block by an adjusting nut. The position of the limit plate can be adjusted back and forth by loosening the adjusting nut. A slide cylinder is installed on the conveyor belt in front of the mounting block. A sliding plate is installed on the slider of the slide cylinder. A push block is slidably installed on the upper part of the sliding plate. The push block is positioned opposite to the limit plate. A spring connects the push block and the sliding plate.

[0011] Furthermore, it also includes a collection box, which is detachably slidably mounted on the left side of the conveyor belt.

[0012] The beneficial effects are as follows: This utility model intermittently transports the relay to the left by the conveyor belt, and the adjustment mechanism can limit the transport of relays of different sizes, thereby improving the compatibility of the equipment; the push block and the limiting plate can fix relays of different sizes, and when the back of the relay is against the front of the limiting plate, the marking position of the relay is just below the laser, thereby improving the marking accuracy.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0019] Example: Laser marking device for relays, such as... Figures 1-3 As shown, the device includes a base 1, a Z-axis module 2, a laser 3, a control panel 4, a conveyor belt 5, and an adjustment mechanism 6. The Z-axis module 2 is fixed to the rear top of the base 1 by bolts. The laser 3 is mounted on the slider of the Z-axis module 2 via an adapter plate. The laser 3 is moved up and down by the Z-axis module 2 to adjust the focal length. The control panel 4 is located on the right side of the Z-axis module 2. The control panel 4 is used to control the marking path. The conveyor belt 5 is installed on the front top of the base 1. The conveyor belt 5 is installed horizontally from left to right. The relay is placed on the right side of the conveyor belt 5. The relay is transported from right to left by the conveyor belt 5. The adjustment mechanism 6 is located on the front and rear sides of the conveyor belt 5. The adjustment mechanism 6 can limit the transport of electrical appliances of different sizes.

[0020] In use: First, adjust the position of the adjusting mechanism 6 according to the size of the relay. Then, place the relay on the top right side of the conveyor belt 5. The conveyor belt 5 will transport the relay to the left. When the relay is transported to below the laser 3, the conveyor belt 5 will stop transporting the relay. The laser 3 will then mark the relay below it. The marked relay will continue to be transported to the right side via the conveyor belt 5. At the same time, the next relay to be marked will move to below the laser 3 and the marking operation will continue. This process will be repeated until the marking operation is completed, at which point the control equipment will stop working. By intermittently transporting the relay to the left by the conveyor belt 5, the adjusting mechanism 6 can limit the transport of relays of different sizes, improving the compatibility of the equipment.

[0021] like Figure 2 and Figure 3As shown, the adjusting mechanism 6 includes a bidirectional lead screw 61, a handwheel 62, a guide rod 63, a limiting strip 64, and a wing bolt 65. A bidirectional lead screw 61, perpendicular to its conveying direction, is horizontally rotatably mounted in the middle of the conveyor belt 5. A handwheel 62 is located at the front end of the bidirectional lead screw 61, allowing for easy rotation of the lead screw 61. Guide rods 63 are symmetrically arranged on both the front and rear sides of the conveyor belt 5. Limiting strips 64 are slidably connected between the guide rods 63 on the same side. The limiting strips 64 slide back and forth on the guide rods 63. The limiting strips 64 are threadedly connected to the bidirectional lead screw 61 and extend upwards to the top of the conveyor belt 5. The bottom of the limiting strips 64 is in contact with the top of the conveyor belt 5. Rotating the bidirectional lead screw 61 can cause the limiting strips 64 to close or open. For larger relays, the distance between the limit bars 64 is greater; for smaller relays, the distance between the limit bars 64 is smaller. During relay transport, the inner side of the limit bar 64 contacts the front and rear sides of the relay. A wing bolt 65 is vertically connected to the front middle of the conveyor belt 5 via a thread. The bottom end of the wing bolt 65 presses against the top of the bidirectional screw 61. When the position of the limit bar 64 needs to be adjusted, the wing bolt 65 is turned upwards, separating the bottom end of the wing bolt 65 from the bidirectional screw 61. At this time, the bidirectional screw 61 can be rotated. After the position of the limit bar 64 is adjusted, the wing bolt 65 is turned downwards and pressed against the top of the bidirectional screw 61 to fix the bidirectional screw 61, so that the position of the limit bar 64 will not easily rotate due to external force.

[0022] like Figure 2 and Figure 4 As shown, it also includes a precision positioning mechanism 7. The precision positioning mechanism 7 is installed on the conveyor belt 5 below the laser 3. The precision positioning mechanism 7 includes a mounting block 71, a limiting plate 72, an adjusting nut 73, a sliding plate 74, a slide cylinder 75, a push block 76, and a spring 77. The mounting block 71 extending upward is fixed to the rear side of the conveyor belt 5 below the laser 3 by bolts. The upper part of the mounting block 71 is slidably connected to the limiting plate 72. The limiting plate 72 is fixed to the mounting block 71 by the adjusting nut 73. The position of the limiting plate 72 can be adjusted back and forth by loosening the adjusting nut 73. The slide cylinder 75 is installed on the conveyor belt 5 in front of the mounting block 71. The sliding plate 74 is installed on the slider of the slide cylinder 75. The push block 76 is slidably installed on the upper part of the sliding plate 74. The push block 76 is opposite to the limiting plate 72. A spring 77 is connected between the push block 76 and the sliding plate 74. The back and forth position of the push block 76 can be changed by the slide cylinder 75.

[0023] Because a more convenient placement of the relay is required, the distance between the limit bars 64 needs to be greater than the width of the relay, which may result in positional errors. Before laser marking, the adjusting nut 73 is loosened according to the size of the relay, and then the front and rear positions of the limit plate 72 are adjusted. When the rear side of the relay is against the front side of the limit plate 72, the marking position of the relay is just below the laser 3. Therefore, when the relay is transported between the limit plate 72 and the push block 76, the sliding plate 74 and its components are moved backward by the slide cylinder 75, and the push block 76 pushes the relay backward. When the relay moves backward and contacts the limit plate 72, the push block 76 can no longer move backward, and the spring 77 is compressed. The push block 76 and the limit plate 72 can fix relays of different sizes. The larger the relay, the greater the compression of the spring 77. After the relay is marked, the sliding plate 74 and its components are moved forward to reset by the slide cylinder 75, and the spring 77 resets, causing the push block 76 to reset.

[0024] like Figure 1 As shown, it also includes a collection box 8. The collection box 8 is detachably slidably installed on the left side of the conveyor belt 5. After the relay is marked, it continues to be conveyed to the left and enters the collection box 8 for collection. After the collection box 8 is full of relays, the collection box 8 can be removed to take off the relays and a new collection box 8 can be installed to collect the relays.

[0025] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
