[0002] In the manufacturing process of adjustable wrenches, the marking operation is a crucial step, which is to mark the adjustable wrench with important information such as product information, specifications, and brand logos.

[0003] Currently, some marking mechanisms used for wrench processing on the market lack effective automatic feeding mechanisms in practical applications. During the marking process, operators need to manually load and unload the movable wrench.

[0004] Specifically, operators need to place each adjustable wrench to be marked into the marking position one by one. After marking is completed, the marked wrench is manually removed and a new wrench to be marked is placed in the position. Operators need to maintain repetitive picking and placing actions for a long time, which is labor-intensive and easily leads to fatigue. Secondly, manual operation is relatively slow, affecting the efficiency of marking.

[0005] To address the above problems, a marking machine for wrench processing is now designed. Utility Model Content

[0006] This application provides a marking machine for wrench processing to solve the problem that some existing wrench marking mechanisms in the related art lack an effective automatic feeding mechanism, requiring operators to manually load and unload the movable wrench during the marking process.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] This application provides a marking machine for wrench processing, which can solve the problem that some existing wrench marking mechanisms in the related art lack an effective automatic feeding mechanism, requiring operators to manually load and unload the movable wrench during the marking process.

[0019] Please see Figures 1-3 A marking machine for processing wrenches includes: a workbench 1, on which a marking mechanism 2 for movable wrenches is provided; The conveying unit 3 is arranged on the workbench 1 and located directly below the marking mechanism 2. The conveying unit 3 includes a loading end 31 and a unloading end 32 for loading and unloading the movable wrench. Multiple material feeding seats 4 are sequentially arranged on the conveying unit 3, and the material feeding seats 4 are used to hold movable wrenches; The marking mechanism 2 includes a laser marking machine 21 arranged on the workbench 1, a vision sensor 22, and a display 23. The laser marking machine 21 is located above the conveying unit 3 and is used to mark the movable wrench. The vision sensor 22 is electrically connected to the laser marking machine 21 and is used to scan and identify the movable wrench. The display 23 is electrically connected to the vision sensor 22 and is used to monitor the marking process.

[0020] The movable wrenches to be marked are placed one by one on the feeding end 31 of the conveying unit 3 and the feeding seat 4 is arranged in sequence on the conveying unit 3 to carry the movable wrenches in an orderly manner. When the conveying unit 3 is started, the feeding seat 4 and the movable wrenches on it are moved from the feeding end 31 of the conveying unit to the position located directly below the marking mechanism 2.

[0021] When the feeding seat 4 carrying the adjustable wrench arrives directly below the marking mechanism 2, the vision sensor 22 starts working. The vision sensor 22 scans and identifies the adjustable wrench, obtains information such as the position, shape, and size of the adjustable wrench, and transmits this information to the laser marking machine 21. Based on the information provided by the vision sensor 22, the laser marking machine 21 adjusts the emission position and parameters of the laser beam and performs a marking operation at the designated position on the adjustable wrench, marking the wrench with an identifier.

[0022] Meanwhile, when the vision sensor 22 identifies the information of the adjustable wrench and monitors the marking process, it transmits relevant images and data to the electrically connected display 23. The display 23 displays this information in real time. The operator can observe the display 23 to understand the identification status of the adjustable wrench, the marking progress, and the marking quality, so as to intervene and adjust in a timely manner.

[0023] After marking is completed, the conveying unit 3 continues to operate, conveying the unloading seat 4 carrying the marked movable wrench to the unloading end 32 of the conveying unit.

[0024] The batch feeding and continuous marking of movable wrenches are achieved through the marking mechanism 2, the conveying unit 3 and the feeding seat 4. There is no need to manually carry each wrench to the marking position, which greatly saves time and manpower, and enables the marking process to be carried out continuously and efficiently, significantly improving the overall production efficiency.

[0025] The application of vision sensor 22 can accurately identify information such as the position, shape and size of the adjustable wrench, providing accurate positioning basis for laser marking machine 21, enabling laser marking machine 21 to accurately mark at the designated position of the adjustable wrench, ensuring the quality and accuracy of marking.

[0026] The marking process can be monitored in real time via the monitor 23, allowing for timely detection and correction of potential problems, such as marking position deviations or errors in marking content, thereby further ensuring the stability of marking quality.

[0027] like Figure 3 and Figure 5 As shown, in one embodiment, the conveying unit 3 includes two U-shaped fixed seats 33 arranged opposite to each other. A rotating shaft 34 is rotatably disposed on the inner side of each fixed seat 33, and a sprocket 35 is disposed on the outer side of the rotating shaft 34. A support plate 331 is disposed between the two fixed seats 33, and there is a gap between the two support plates 331. A chain conveyor belt 36 is drivenly connected between the outer sides of the two sprockets 35. The upper wall of the inner side of the chain conveyor belt 36 is in contact with the upper surface of the support plate 331. A plurality of auxiliary rollers 37 are rotatably disposed between the two support plates 331, and the auxiliary rollers 37 are in contact with the lower surface of the chain conveyor belt 36.

[0028] In one embodiment, the conveying unit 3 further includes a drive motor 38 and a reducer 39 mounted on a side fixed base 33. The output shaft of the drive motor 38 is connected to the input shaft of the reducer 39, and the input shaft of the reducer 39 is connected to one end of a side rotating shaft 34.

[0029] When the device is turned on, the drive motor 38 is powered on and runs, converting electrical energy into mechanical energy. Its output shaft begins to rotate, and the power is transmitted to the reducer 39. The reducer 39 reduces the power and increases the torque through internal gears and other transmission structures, and then transmits the processed power to one end of the rotating shaft 34 connected to it.

[0030] The shaft 34 starts to rotate under the power drive. Since there is a sprocket 35 on the outside of the shaft 34, the sprocket 35 also rotates. The sprockets 35 on the two oppositely arranged fixed seats 33 are linked by the chain plate conveyor belt 36 connected by the transmission between the outer sides. The rotation of the sprocket 35 drives the chain plate conveyor belt 36 to circulate along the trajectory of the sprocket 35.

[0031] The upper wall of the inner side of the chain conveyor belt 36 is in contact with the upper surface of the support plate 331. The support plate 331 provides stable support for the chain conveyor belt 36 to prevent it from sagging and deforming due to bearing heavy objects such as adjustable wrenches.

[0032] The auxiliary roller 37 contacts the lower surface of the chain conveyor belt 36. As the chain conveyor belt 36 rotates, the auxiliary roller 37 rotates, which plays a role in providing auxiliary support and reducing friction, making the chain conveyor belt 36 run more smoothly.

[0033] The adjustable wrench is placed on the feeding seat 4 on the chain conveyor belt 36. As the chain conveyor belt 36 rotates, the adjustable wrench is transported from the feeding end 31 of the conveying unit 3 to the area directly below the marking mechanism 2 for marking operation. After marking is completed, it is transported to the unloading end 32.

[0034] like Figure 3 and Figure 5 As shown, in one embodiment, the chain conveyor belt 36 is formed by hinged multiple chain plates 361.

[0035] The chain conveyor belt 36 is composed of multiple chain plates 361 hinged together. Each chain plate 361 is connected to the others by hinge points such as pins, which allows the chain plates 361 to rotate relative to each other. When a chain plate 361 starts to move under the drive of the sprocket 35, it transmits power to the adjacent chain plates 361 through the hinge points.

[0036] When the chain conveyor belt 36 reaches the sprocket 35, it needs to turn. Since the chain plates 361 are hinged, they can rotate around the hinge point under the action of the sprocket 35.

[0037] The teeth of the sprocket 35 mesh with different chain plates 361 in sequence, guiding the chain plates 361 to move along the circumference of the sprocket 35, thereby realizing the turning of the chain plate conveyor belt 36.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, a plurality of feeding seats 4 are disposed on the corresponding chain plates 361; The material feeding seat 4 includes two fixed posts 41 arranged opposite to each other on the chain plate 361, and a material plate 42 arranged on the corresponding two fixed posts 41. The material plate 42 has a receiving groove 43 for placing a movable wrench. The receiving groove 43 is adapted to the wrench. The receiving groove 43 has a protrusion 431, which is adapted to the groove on the side of the movable wrench.

[0039] The feeding seat 4 is set on the corresponding chain plate 361 to ensure that each chain plate 361 can support a feeding seat 4, so that the entire conveying system can stably support the movable wrench during the conveying process.

[0040] When the adjustable wrench is placed in the receiving groove 43, the wrench can be accurately placed into the receiving groove 43 because the shape and size of the receiving groove 43 are adapted to the adjustable wrench.

[0041] Meanwhile, the protrusion 431 on the receiving groove 43 is adapted to the groove on the side of the adjustable wrench. When the adjustable wrench is placed into the receiving groove 43, the protrusion 431 will be embedded in the groove of the adjustable wrench, which plays a role in positioning and fixing, preventing the adjustable wrench from shaking or shifting during the conveying process.

[0042] like Figure 1 As shown, in one embodiment, a receiving unit 5 is also included, which includes a belt conveyor 51 arranged at the bottom of the discharge end 32 and a baffle 52 arranged above the belt conveyor 51. The baffle 52 is U-shaped and has an open end near the discharge end 32. The belt conveyor 51 uses a rubber conveyor belt.

[0043] When the chain conveyor belt 36 transports the adjusted wrench, which has been processed, to the unloading end 32, the adjusted wrench will fall off the chain conveyor belt 36 under the action of gravity.

[0044] Meanwhile, the belt conveyor 51 located at the bottom of the unloading end 32 is in continuous operation. When the adjustable wrench falls from the chain conveyor belt 36, it lands on the running belt conveyor 51. The belt surface of the belt conveyor 51 has a certain friction force, which can drive the adjustable wrench to move forward with the belt.

[0045] Subsequently, the dropped adjustable wrench is received through the open end of the U-shaped baffle 52. As the belt conveyor 51 operates, the adjustable wrench is gradually guided under the constraint of the baffle 52. The two side walls of the baffle 52 can prevent the adjustable wrench from slipping off the sides of the belt during the conveying process, ensuring that the adjustable wrench can be stably conveyed along the set direction of the belt conveyor 51.

[0046] A belt conveyor 51 typically consists of a belt, a drive roller, a driven roller, and idlers. The drive roller rotates under the drive of a motor, driving the belt through friction. The driven roller supports and changes the direction of belt movement, while the idlers support the belt and reduce resistance during belt movement. This is existing technology and will not be elaborated further.

[0047] The continuous operation of the belt conveyor 51 enables the continuous collection of the adjustable wrench, improving the speed and efficiency of material collection. At the same time, the guidance and collection of the baffle 52 allows the adjustable wrench to quickly enter the material collection process.
