Description

Technical Field

[0001] This application relates to the field of marking equipment, and in particular to a shaft marking machine with automatic loading and unloading. Background Technology

[0002] In the automotive manufacturing industry, shaft parts (mandrels, drive shafts, etc.) are core components for power transmission and motion conversion, making quality traceability and production management crucial. To achieve identification and full lifecycle management of each part, it is usually necessary to permanently mark its surface with information such as model number and production batch.

[0003] The existing patent with publication number CN222179041U discloses a support mechanism for a pneumatic marking machine for automotive shaft parts, including: a worktable with two sliding seats on the top of the worktable, and a clamping frame fixedly connected inside the sliding seats; a sliding assembly that can adjust the distance between the two sliding seats; and two clamping assemblies with identical structures, each located inside a clamping frame. By adjusting the distance between the two sliding seats, shaft parts of different lengths can be clamped by the two clamping assemblies.

[0004] In the aforementioned existing technology, operators still need to manually move the shaft parts to be marked from the material rack to the marking machine's worktable, roughly position them, start the marking program, and then manually remove the parts for sorting and placement after marking is completed. This results in low efficiency and high labor intensity for operators. Utility Model Content

[0005] In order to improve the efficiency of marking machine loading and unloading and reduce the intensity of manual labor, this application provides a shaft marking machine with automatic loading and unloading.

[0006] The automatic loading and unloading shaft marking machine provided in this application adopts the following technical solution:

[0007] An automatic loading and unloading shaft marking machine includes a marking machine body, the body being provided with a material distribution mechanism, and the body also being provided with an electric slide table mounted above the material distribution mechanism. The electric slide table is slidably provided with a loading mechanism and a unloading mechanism, the loading mechanism being located in front of the material distribution mechanism and the unloading mechanism being located behind the material distribution mechanism.

[0008] By adopting the above technical solution, the electric slide table drives the feeding mechanism and the unloading mechanism to move laterally. After the feeding mechanism picks up the blank, it is transferred to the sorting mechanism by the electric slide table. The blank is marked and transferred on the sorting mechanism. Then the electric slide table drives the unloading mechanism to remove the marked blank and realize automatic unloading, which improves the efficiency of loading and unloading, realizes automatic loading and unloading, and reduces the intensity of manual labor.

[0009] Optionally, the feeding mechanism includes a first slide block slidably disposed on the electric slide table, a first lifting rod slidably disposed on the first slide block along the vertical direction, a first driving assembly for driving the first lifting rod to rise and fall, and a feeding assembly connected to the lower end of the first lifting rod. The feeding assembly is used to pick up materials and place the workpieces on the material distribution mechanism.

[0010] By adopting the above technical solution, the first slide block can achieve lateral displacement along the electric slide table, the first lifting rod can achieve lifting and lowering under the drive of the first drive component, and after the feeding component picks up the material, it can drive the workpiece to move in both vertical and horizontal dimensions, making it easier to move the workpiece to the material distribution mechanism on the worktable.

[0011] Optionally, the feeding assembly includes a magnetic gripper rotatably connected to the lower end of the first lifting rod.

[0012] By adopting the above technical solution, the feeding component uses magnetic grippers. The magnetic switch is controlled by controlling the current of the electromagnet, thereby realizing the picking up or unloading of materials, which is convenient for picking up and unloading materials.

[0013] Optionally, the unloading mechanism includes a second slide block slidably disposed on the electric slide table, a second lifting rod slidably disposed on the second slide block along the vertical direction, a second drive assembly for driving the second lifting rod to rise and fall, and an unloading assembly connected to the lower end of the second lifting rod. The unloading assembly is used to remove and send out the workpiece from the material distribution mechanism.

[0014] By adopting the above technical solution, the second slide block achieves lateral displacement along the electric slide table, and the second lifting rod achieves lifting and lowering under the driving action of the second drive component. After the unloading component picks up the workpiece, the workpiece is automatically unloaded by lifting and lowering the second lifting rod and moving the second slide block laterally, saving manpower.

[0015] Optionally, the unloading assembly includes a magnetic gripper rotatably connected to the lower end of the second lifting rod.

[0016] By adopting the above technical solution, the feeding component uses magnetic grippers. By controlling the current of the electromagnet to control the magnetic switch, the material can be picked up or put out, making it more convenient to pick up and put out materials.

[0017] Optionally, the material distribution mechanism includes a loading box inclinedly disposed on the main worktable, a material distribution component disposed behind the loading box, and a unloading box disposed behind the material distribution component. The loading box is used to receive the workpieces conveyed by the loading mechanism, and the unloading box is used for the unloading mechanism to pick up the materials.

[0018] By adopting the above technical solution, after the feeding mechanism picks up the material, it places the workpiece in the feeding box. Since the feeding box is set at an inclination, the bar rolls down to the material distribution unit. The material distribution unit rotates to transfer the workpiece to the unloading box. The bar is stored in the unloading box for easy picking by the unloading mechanism.

[0019] Optionally, the material distribution component includes a bracket fixed to the worktable surface of the main body, a rotating shaft rotatably disposed on the bracket, and a support ring fixedly disposed on the rotating shaft. The support ring is provided with a plurality of material distribution grooves for inserting shaft-type workpieces in the circumferential direction. The main body is also provided with a driving component for driving the rotating shaft to rotate.

[0020] By adopting the above technical solution, the shaft-type workpieces in the loading box roll to a position close to the support ring. The support ring rotates under the drive of the drive component. When the distribution groove on the support ring rotates to align with the workpiece in the loading box, the workpiece will roll into the distribution groove. Then the support ring continues to rotate until the workpiece is in the marking position for marking. After that, the support ring continues to rotate until the workpiece rotates to align with the unloading box. The workpiece rolls from the distribution groove to the unloading box, completing the material distribution.

[0021] Optionally, the material distribution trough is opened in the shape of a right trapezoid, and the side wall of the material distribution trough located on the front side along the rotation direction of the supporting ring is the hypotenuse of the right trapezoid.

[0022] By adopting the above technical solution, the material distribution trough is a right-angled trapezoid. When the material distribution trough rotates to the side of the loading box, shaft-type workpieces roll into the material distribution trough. At this time, the right-angled side of the material distribution trough is at the bottom and the inclined side is at the top. As the supporting ring rotates, the right-angled side can drive the workpiece to rotate synchronously. When the supporting ring continues to rotate and approaches the unloading box, the inclined side is at the bottom, and the workpiece in the material distribution trough will roll along the inclined side into the unloading box to realize unloading.

[0023] Optionally, a feeding basket is provided on the front side of the main body, and a discharging basket is provided on the rear side of the main body.

[0024] By adopting the above technical solution, the feeding basket can pre-store a portion of the blank material, which is convenient for the feeding mechanism to clamp, and the unloading basket can store the marked workpieces, which is convenient for unloading.

[0025] Optionally, the feeding box is provided with a clearance groove for the feeding assembly to extend into.

[0026] By adopting the above technical solution, when the feeding component is transferred to the top of the feeding box to pick up the material, the collision and interference between the feeding component and the feeding box can be avoided by opening the avoidance groove.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The loading mechanism automatically clamps the workpiece to the sorting mechanism, the sorting mechanism transfers the workpiece and completes the marking, and the unloading mechanism automatically clamps the workpiece and completes the unloading. This can realize the automatic loading and unloading of shaft workpieces, improve the marking efficiency and reduce manual labor.

[0029] 2. The workpiece is rotated by the rotation of the material distribution component, which realizes the transfer of the workpiece from the loading box to the unloading box. The workpiece can also be automatically moved to the marking position. Since the rotation angle of the material distribution component is fixed, the marking position of the workpiece is fixed, which improves the marking accuracy compared with manual loading.

[0030] 3. By using magnetic grippers to pick up and place workpieces, and by using electromagnetic attraction to pick up workpieces, there will be no clamping damage to the workpieces, which reduces the defect rate to a certain extent. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] This application discloses an automatic loading and unloading shaft marking machine. (Refer to...) Figure 1 and Figure 2 The automatic loading and unloading shaft marking machine includes a marking machine body 1. A material distribution mechanism 2 is set on the worktable of the body 1. An electric slide table 4 is also set on the body 1 above the material distribution mechanism 2. Two slide seats are slidably set on the electric slide table 4, namely a first slide seat 9 and a second slide seat 13. The electric slide table 4 and the slide seats can be driven by a gear and rack, or by a lead screw and slider. In this embodiment, the gear and rack method is used to achieve the drive. That is, a motor is fixedly installed on both the first slide seat 9 and the second slide seat 13. The output shaft of the motor is fixed with a gear. A rack that meshes with the two gears is fixed on the body 1 of the electric slide table 4. The first slide seat 9 and the second slide seat 13 are moved by the rotation of the motor.

[0039] A feeding basket 5 for storing blanks is provided on the front side of the marking machine body 1, and a discharging basket 6 for storing finished products is provided on the rear side of the marking machine body 1. A feeding mechanism 7 and a discharging mechanism 8 are slidably arranged on the electric slide table 4. The feeding mechanism 7 includes a first slide 9, a first lifting rod 10, a first drive assembly 11, and a feeding assembly 12. The first lifting rod 10 is slidably connected to the first slide 9 in the vertical direction. The first drive assembly 11 includes a motor fixed to the first slide 9, a gear fixedly connected to the output shaft of the motor, and a rack fixedly installed on the first lifting rod 10. The first lifting rod 10 is driven to lift and lower through the meshing of the gear and the rack.

[0040] like Figure 2As shown, the feeding assembly 12 uses magnetic grippers, which are rotatably connected to the lower end of the first lifting rod 10 via a universal joint. The magnetic grippers utilize commercially available electromagnetic clamps or electromagnetic chucks, controlling the on / off state of the electromagnet to pick up or unload the workpiece. Furthermore, because the magnetic grippers are connected to the first lifting rod 10 via a universal joint, the angle of the magnetic grippers can be automatically adjusted when the first lifting rod 10 descends to pick up the workpiece, resulting in better gripping of shaft-type workpieces. Simultaneously, the magnetic grippers reduce clamping damage to the workpiece by magnetically attracting it.

[0041] The unloading mechanism 8 includes a second slide block 13, a second lifting rod 14, a second drive assembly 15, and an unloading assembly 16. The second lifting rod 14 is slidably connected to the second slide block 13 in the vertical direction. The second drive assembly 15 includes a motor fixed to the second slide block 13, a gear fixedly connected to the output shaft of the motor, and a rack fixedly installed on the second lifting rod 14. The second lifting rod 14 is driven to lift and lower through the meshing of the gear and the rack.

[0042] The unloading assembly 16 uses the same magnetic gripper as the loading assembly 12. The magnetic gripper is connected to the second lifting rod 14 through a universal joint. The workpiece is picked up or unloaded by controlling the on and off of the electromagnet, making unloading more convenient.

[0043] like Figure 3 As shown, the material distribution mechanism 2 includes a feeding box 17, a material distribution component 18, and a discharging box 19 arranged sequentially on the worktable of the main body 1. The feeding box 17 and the discharging box 19 are both inclined and in the same direction. The feeding end of the feeding box 17 and the discharging box 19 is higher than the discharging end. The material distribution component 18 is located between the feeding box 17 and the discharging box 19 and connects the two.

[0044] The material distribution component 18 includes a bracket 20 fixed to the worktable surface of the main body 1, a rotating shaft 21 rotatably mounted on the bracket 20, and a support ring 22 fixedly mounted on the rotating shaft 21. The rotating shaft 21 is parallel to the shaft-like workpiece, and the support ring 22 is coaxially fixed to the rotating shaft 21. A drive component 23 for driving the rotating shaft 21 is also provided on the main body 1. The drive component 23 uses a motor belt structure, meaning the motor is fixed to the main body 1, and pulleys are provided on both the motor's output shaft and the rotating shaft 21. The two pulleys are connected by a belt, thereby driving the rotating shaft 21 and the support ring 22 to rotate through the rotation of the motor. The lower edge of the loading box 17 is close to the outer circumference of the support ring 22, and the higher edge of the unloading box 19 is close to the outer circumference of the support ring 22, allowing for better connection between the three components.

[0045] In this embodiment, two support rings 22 are provided, and four material distribution grooves 24 are equally spaced around the support rings 22. The material distribution grooves 24 are used for inserting shaft-type workpieces. The shape of the material distribution grooves 24 is a right trapezoid with an open bottom edge. Along the direction of rotation of the support rings 22, the side wall of the material distribution groove 24 located on the front side is a slanted side, and the side wall of the material distribution groove 24 located on the rear side is a right angle side. Therefore, when the material distribution trough 24 rotates to the side near the loading box 17, due to the inclined setting of the loading box 17, shaft-type workpieces can roll into the material distribution trough 24. At this time, the right-angled side of the material distribution trough 24 is at the bottom and the inclined side is at the top. As the supporting ring 22 rotates, the right-angled side can drive the workpiece to rotate synchronously. When the supporting ring 22 rotates to the point where the workpiece is directly above the supporting ring 22, the marking machine marks the workpiece. When the supporting ring 22 continues to rotate to the side near the unloading box 19, the inclined side is at the bottom, and the workpiece in the material distribution trough 24 will roll along the inclined side into the unloading box 19 and be stored, which facilitates the unloading assembly 16 to pick up and unload the workpiece. In order to avoid interference between the unloading assembly 16 and the unloading box 19, an avoidance groove 25 is provided on the side of the unloading box 19 near the unloading basket 6. The avoidance groove 25 is located on the movement trajectory of the unloading assembly 16.

[0046] The implementation principle of an automatic loading and unloading shaft marking machine according to an embodiment of this application is as follows: the blank is stored in the loading basket 5. The first sliding block 9 drives the first lifting rod 10 to move above the loading basket 5. Then, the first lifting rod 10 drives the loading assembly 12 to descend and pick up the workpiece. After that, the workpiece is placed in the loading box 17 for temporary storage. The supporting ring 22 rotates until one of the distributing grooves 24 approaches and aligns with the workpiece in the loading box 17. The workpiece in the loading box 17 rolls into the distributing groove 24. As the supporting ring 22 rotates... The right-angled side can drive the workpiece to rotate synchronously. When the support ring 22 rotates to the position of the workpiece directly above the support ring 22, the marking machine marks the workpiece. When the support ring 22 continues to rotate to the position of the feeding box 19, the inclined side is down. The workpiece in the distribution groove 24 will roll along the inclined side into the feeding box 19 and be stored. Then the second slide 13 and the second lifting rod 14 drive the feeding assembly 16 to move to the feeding box 19 and pick up the marked workpiece. Finally, the workpiece is transferred to the feeding basket 6 to complete the feeding.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
