Description

Technical Field

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

[0002] Laser marking equipment requires a feeding device to move the workpiece to be marked.

[0003] A search revealed an existing technology that discloses an automatic feeding mechanism (publication number: CN210649046U), comprising a motor, a coupling, a bearing, a support base, a connecting rod, a roller, a pallet, and a material belt. The support base includes a first support arm and a second support arm. The first support arm has a first through hole, and the second support arm has a second through hole. The roller has an adjustable pushing part, and the material belt has a through part adapted to the pushing part. The bearing is fixed in the first through hole, the motor is fixed on the outer wall of the first support arm, the roller is sleeved on the connecting rod, one end of the connecting rod passes through the bearing and is fixedly connected to the motor shaft via the coupling, and the other end is located in the second through hole. The pallet is fixed between the first and second support arms, and the material belt is located between the pallet and the roller. The motor drives the shaft to rotate, the shaft drives the coupling to rotate, the coupling drives the connecting rod to rotate, the connecting rod drives the roller to rotate, and the pushing part on the roller passes through the through part, thereby pushing the material belt to move.

[0004] Existing technology achieves workpiece conveying through the linear movement of a conveyor belt, which requires friction wheel drive: the conveyor belt is pulled by friction through a motor-driven rubber wheel. Over time, the length of the conveyor belt will change, causing it to loosen, which in turn affects the transmission of the conveyor belt, making it prone to slippage and resulting in low positioning accuracy. There is room for optimization.

[0005] Therefore, we propose a feeding device for laser marking equipment. Utility Model Content

[0006] The present invention mainly addresses the technical problems of low accuracy and easy slippage in the belt drive mentioned above, and provides a feeding device for laser marking equipment.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a feeding device for a laser marking equipment, comprising: A frame is provided, on which a timing belt is mounted, and a material belt for loading is mounted on the timing belt. A servo motor for driving the timing belt is fixed on one side of the frame. An adjustment structure, located at the top of the frame, is used to adjust the tension of the timing belt. The adjustment structure includes a support frame, a top block, a roller, a smooth head screw, and a spring. The support frame is fixedly installed on the frame. The top block is slidably mounted on the support frame. The smooth head screw is slidably connected to the support frame. The spring is sleeved on the outside of the smooth head screw. The smooth head screw is fixedly connected to the top block. The roller is rotatably connected to the top block. The spring can push the smooth head screw to push the top block closer to the timing belt.

[0008] In a preferred embodiment of this utility model, the adjustment structure further includes guide rods, with two guide rods provided at the bottom of the top block, and the top block is slidably connected to the support frame.

[0009] In a preferred embodiment of this utility model, the guide rod is fixedly connected to the bottom surface of the top block, and a sliding sleeve that is clearance-fitted with the guide rod is fixedly installed on the support frame, with the guide rod and the sliding sleeve being slidably connected.

[0010] In a preferred embodiment of this utility model, the support frame has a through hole adapted to the sprue screw, the sprue screw is slidably disposed in the hole, and the spring is disposed above the support frame.

[0011] In a preferred embodiment of this utility model, the adjustment structure further includes an adjustment nut and a locking ring. The adjustment nut is threadedly connected to the polished head screw and adjusts the preload of the spring. The locking ring is slidably connected to the polished head screw and can engage with the adjustment nut to restrict its rotation.

[0012] In a preferred embodiment of this utility model, the adjustment structure further includes a sliding channel, wherein the circumferential surface of the optical head screw is provided with a sliding channel along the radial direction, and the locking ring is fixedly provided with a protrusion, which is slidably disposed within the sliding channel.

[0013] In a preferred embodiment of this utility model, the adjustment structure further includes a magnet and a thrust groove. The magnet is fixedly connected to the locking ring, and several thrust grooves are formed on the upper surface of the adjusting nut. The magnet can attract the adjusting nut and engage it in the thrust groove.

[0014] This utility model provides a feeding device for laser marking equipment. It has the following beneficial effects: 1. The feeding device of this laser marking equipment uses the elastic force of a spring to push the laser head screw upward, which in turn drives the top block and roller shaft upward. The roller shaft then contacts the bottom of the synchronous belt to adjust its tension. Meanwhile, the guide rod slides along the sliding sleeve to ensure the stability of the top block's displacement, preventing the synchronous belt from loosening over time and affecting the meshing stability between the synchronous pulley and the synchronous belt. This achieves dynamic compensation for the tension of the synchronous belt, ensuring the accuracy of the synchronous belt and material conveying. It is a purely mechanical structure with high reliability and lower cost than an electrically controlled tensioning system.

[0015] 2. The feeding device of this laser marking equipment can compress a spring by rotating the adjusting nut. A shim can be placed between the adjusting nut and the spring to avoid motion interference. The adjusting nut may be affected by the vibration of the synchronous belt. By setting a magnet, the adjusting nut is attracted and locked into the thrust groove at the corresponding position. The locking ring is slidably connected to the laser head screw, so the locking ring can lock the adjusting nut and limit the circumferential rotation of the adjusting nut, thus ensuring the stability of the adjusting nut locking.

[0016] 3. The feeding device of this laser marking equipment, when it is necessary to rotate the adjusting nut to adjust the preload value of the spring, can be operated by pushing the locking ring upward by hand, the magnet disengages from the thrust groove, and the protrusion of the locking ring slides along the sliding channel. At this time, the adjusting nut can be freely rotated to adjust the preload value of the spring, which has the characteristics of being easy to operate and use. Attached Figure Description

[0019] A feeding device for laser marking equipment, such as Figure 1 and Figure 2 As shown, it includes: The frame 10 is equipped with a timing belt 11, and a material belt 12 for loading is mounted on the timing belt 11. A servo motor 13 for driving the timing belt 11 is fixed on one side of the frame 10. Specifically, the servo motor 13 forms a closed-loop control by connecting the encoder and the controller. The output shaft of the servo motor 13 is fixedly equipped with a synchronous pulley. The synchronous pulley meshes with the synchronous belt 11 and is rotatably connected to the frame 10 to drive the synchronous belt 11. The synchronous belt 11 drives the material belt 12 to move linearly to realize the conveying and feeding of the workpiece.

[0020] like Figure 2, Figure 3 and Figure 4 As shown, the adjustment structure, located on top of the frame 10, is used to adjust the tension of the synchronous belt 11. The adjustment structure includes a support frame 20, a top block 21, a roller shaft 22, a polished screw 24, and a spring 25. The support frame 20 is fixedly installed on the frame 10. The top block 21 is slidably mounted on the support frame 20. The polished screw 24 is slidably connected to the support frame 20. The spring 25 is sleeved on the outside of the polished screw 24. The polished screw 24 is fixedly connected to the top block 21. The roller shaft 22 is rotatably connected to the top block 21. The spring 25 can push the polished screw... The rod 24 pushes the top block 21 close to the synchronous belt 11. The adjustment structure also includes guide rods 23. Two guide rods 23 are set at the bottom of the top block 21. The top block 21 is slidably connected to the support frame 20. The guide rods 23 are fixedly connected to the bottom surface of the top block 21. The support frame 20 is fixedly installed with a sliding sleeve that is clearance-fitted with the guide rods 23. The guide rods 23 are slidably connected to the sliding sleeve. The support frame 20 has a hole through which the optical head screw 24 is adapted. The optical head screw 24 is slidably set in the hole. The spring 25 is set above the support frame 20. In this scheme, the spring force of the spring 25 pushes the polished screw 24 upward, which in turn drives the top block 21 and roller 22 upward. As a result, the roller 22 can contact the bottom of the synchronous belt 11 to adjust the tension of the synchronous belt 11. Meanwhile, the guide rod 23 slides along the sliding sleeve to ensure the stability of the displacement of the top block 21. This prevents the synchronous pulley from being affected by the loosening of the synchronous belt 11 due to long-term use, thus achieving dynamic compensation for the tension of the synchronous belt 11. The accuracy of the synchronous belt 11 and the material belt 12 transmission is thus guaranteed.

[0021] like Figure 3 , Figure 4 and Figure 5 As shown, the adjustment structure also includes an adjustment nut 30 and a locking ring 31. The adjustment nut 30 is threadedly connected to the polished screw 24 and adjusts the preload of the spring 25. The locking ring 31 is slidably connected to the polished screw 24. The locking ring 31 can engage with the adjustment nut 30 and restrict the rotation of the adjustment nut 30. The adjustment structure also includes a sliding channel 32. The circumferential surface of the polished screw 24 has a sliding channel 32 opened radially. The locking ring 31 is fixedly provided with a protrusion, which is slidably disposed in the sliding channel 32. The adjustment structure also includes a magnet 33 and a thrust groove 34. The magnet 33 is fixedly connected to the locking ring 31. The upper end surface of the adjustment nut 30 has several thrust grooves 34. The magnet 33 can attract the adjustment nut 30 and engage it in the thrust groove 34. To adjust the preload value of spring 25, spring 25 can be compressed by rotating adjusting nut 30. A shim can be placed between adjusting nut 30 and spring 25 to avoid motion interference. Adjusting nut 30 may be affected by the vibration of synchronous belt 11. By setting magnet 33, adjusting nut 30 is attracted and locked into thrust groove 34 at the corresponding position. Locking ring 31 is slidably connected to smooth screw 24, so locking ring 31 can lock adjusting nut 30 and limit the circumferential rotation of adjusting nut 30, thus ensuring the stability of adjusting nut 30 locking.

[0022] When it is necessary to rotate the adjusting nut 30 to adjust the preload value of the spring 25, the locking ring 31 is pushed upward by hand, the magnet 33 disengages from the thrust groove 34, and the protrusion of the locking ring 31 slides along the sliding channel 32. At this time, the adjusting nut 30 can be rotated freely to adjust the preload value of the spring 25, which has the characteristics of being easy to operate and use.

[0023] The working principle of this utility model is as follows: By manually pushing the locking ring 31 upwards, the magnet 33 disengages from the thrust groove 34. The protrusion of the locking ring 31 slides along the sliding channel 32. At this time, the adjusting nut 30 can be freely rotated to adjust the preload value of the spring 25. Rotating the adjusting nut 30 compresses the spring 25. A shim can be placed between the adjusting nut 30 and the spring 25 to avoid interference. The magnet 33 attracts the adjusting nut 30 and engages it in the corresponding thrust groove 34. The locking ring 31 and... The slidable screw 24 is slidably connected, so the locking ring 31 can lock the adjusting nut 30 and limit the circumferential rotation of the adjusting nut 30, thus ensuring the stability of the adjusting nut 30 locking. The spring force of the spring 25 pushes the slid screw 24 to move upward, and the slid screw 24 drives the top block 21 and the roller shaft 22 to move upward. Thus, the roller shaft 22 can contact the bottom of the synchronous belt 11 to adjust the tension of the synchronous belt 11, while the guide rod 23 slides along the sliding sleeve to ensure the stability of the displacement of the top block 21.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
