The straightness measuring device 4 transmits the collected data to the controller, the controller analyzes the data to obtain the bending position of the round bar, and instructs the sorting device 6 to transfer the round bar to the corresponding roller slide rail 5 to adjust the maximum bending position of the round bar to face the preset direction.

[0054] The above technical solution realizes the automation of the straightness detection of the round bar, compared with the traditional manual detection method, the measurement equipment improves the accuracy and work efficiency of the straightness measurement, reduces the labor intensity of the workers, and reduces the physical discomfort caused by long-time repetitive work.

[0055] Please refer to Figure 1 and Figure 2 In the embodiment, the hopper 11 includes two L-shaped support plates 111, two high-low bases 112 and two first translation assemblies 113; the support plates 111 are obliquely arranged on the high-low bases 112, the front end of the support plate 111 is higher than the rear end, the high-low bases 112 are slidingly arranged on the first translation assemblies 113, the first translation assemblies 113 are used to move the high-low bases 112 and the support plates 111 along the first direction to adjust the width between the two support plates 111, one support plate 111 corresponds to one high-low base 112 and one first translation assembly 113, and the two support plates 111 are oppositely arranged along the first direction and used to support at least one round bar. When it is necessary to adapt to round bars of different lengths, the operator can adjust the distance between the two support plates 111, i.e. change the width of the hopper 11, by moving the high-low bases 112 along the direction of the first translation assemblies 113. Since the support plates 111 are obliquely arranged and the front end is higher than the rear end, the round bar placed thereon will naturally roll towards the lower end, facilitating the subsequent round bar separating mechanism 12 to receive the round bars from the hopper 11 one by one.

[0056] Preferably, the high-low bases 112 are hingedly connected with the support plates 111 through hinges 114 on both sides of the high-low bases 112 along the second direction, so that the inclination of the support plates 111 can be adjusted.

[0057] Please refer to Figure 1 and Figure 2In the embodiment, the round bar separating mechanism 12 comprises a lifting fork 121 and a first lifting assembly 122. The lifting fork 121 is located between the two support plates 111 and is used to receive the round bars one by one. The first lifting assembly 122 is located below the lifting fork 121 and is used to lift the lifting fork 121. When it is necessary to separate a single round bar, the first lifting assembly 122 is activated to lift the lifting fork 121 to a proper height to lift the round bar at the end of the support plate 111.

[0058] Referring to Figure 2 In the embodiment, the lifting fork 121 comprises two vertical plates 1211 arranged side by side along a first direction and a horizontal plate 1212 connecting the two vertical plates 1211. The top of the vertical plate 1211 is provided with a third groove 1213 for receiving the round bar. The horizontal plate 1212 is arranged on the first lifting assembly 122. The round bar separating mechanism 12 further comprises a supporting bracket 123 arranged between the two vertical plates 1211 and used to support the round bar lowered by the lifting fork 121. In the initial state, the lifting fork 121 is in a lower position, and the third groove 1213 at the top of the vertical plate 1211 is lower than the round bar on the support plate 111. When it is necessary to separate the round bar, the first lifting assembly 122 drives the horizontal plate 1212 to rise, thereby driving the vertical plate 1211 and the third groove 1213 at the top of the vertical plate 1211 to move upward. As the third groove 1213 gradually rises, it will contact the round bar and lift it. The position of the supporting bracket 123 is higher than the position of the end of the support plate 111, and the supporting bracket 123 is slightly behind the lifting fork 121. During the lifting process of the lifting fork 121, the round bar can be abutted against the front side wall of the supporting bracket 123 and then slide into the fourth groove 1231. The supporting bracket 123 temporarily stores the round bar and waits for the subsequent first conveying device 2 to carry. Preferably, the third groove 1213 and the second groove 221 are V-shaped. In some embodiments, the supporting bracket 123 can not be provided, and the single round bar can be stored by the lifting bracket and wait for the first conveying device 2 to carry.

[0059] Referring to Figure 2 In the embodiment, the supporting bracket 123 comprises a vertical plate 1232 and two supporting rods 1233. The vertical plate 1232 is arranged on the first fixed seat of the hopper 11 and located between the rear ends of the two support plates 111. The round bar is blocked by the vertical plate 1232 when it slides downward along the inclined support plate 111. The rear side wall of the vertical plate 1232 is provided with the two supporting rods 1233, and the top of the supporting rod 1233 is provided with the fourth groove 1231 for receiving the round bar. The lifting fork 121 lifts the round bar upward from the lower position until it is higher than the vertical plate 1232, and the round bar enters the fourth groove 1231 under the action of gravity. It should be noted that the first fixed seat also supports the two first translation assemblies 113.

[0060] Referring to Figure 1 and Figure 3In the embodiment, the first conveying device 2 comprises an inner guide rail 21, an outer guide rail 22, a second translation assembly 23 and a second lifting assembly 24. The inner guide rail 21 is provided with a plurality of first grooves 211 for limiting the round bar along a second direction. The outer guide rail 22 is located on both sides of the inner guide rail 21 along a first direction. The first direction is perpendicular to the second direction.

The controller is connected with the second translation assembly 23 and the second lifting assembly 24 respectively, and can control the operation of the second translation assembly 23 and the second lifting assembly 24. It should be noted that the left and right sides of the inner guide rail 21 can be connected by sheet metal parts. Optionally, the inner guide rail 21 can be provided with five first grooves 211 in sequence along the length direction. The outer guide rail 22 can be provided with four second grooves 221 along the length direction. Preferably, the second fixed seat is provided with a support for the second translation assembly 23 and a bracket below the outer guide rail 22, as shown in Figure 3 The inner guide rail 21 is kept at a lower position by the second lifting assembly 24, and the round bar is lifted from the lower direction of the round bar separating mechanism 12. Then, the inner guide rail 21 is translated along the second direction and placed on the outer guide rail 22. The second grooves 221 of the outer guide rail 22 can fix the round bar. If the current process is not ready to receive more round bars, or the conveying rhythm needs to be adjusted, the round bar can be temporarily placed in the second grooves 221 of the outer guide rail 22 to play a buffering and temporary storage role. In some embodiments, the outer guide rail 22 can not be provided, and only the inner guide rail 21 is used to convey and store the round bar.

[0061] In the embodiment, the second direction is the width direction of the device, and the first direction is the length direction of the device.

The controller is connected with the laser sensor assembly 41 and the third translation assembly 42 respectively, and can control the operation of the laser sensor assembly 41 and the third translation assembly 42. The third translation assembly 42 moves the entire laser sensor assembly 41 along the first direction (parallel to the axial direction of the round bar above), so that the laser sensor can continuously scan in the full length range of the round bar. The data collected by all sensors are sent to the controller, and the controller processes these data using an algorithm to generate a three-dimensional profile of the round bar, and determines whether the round bar is bent and the specific position and degree of the bending according to the three-dimensional profile, thereby avoiding the error caused by local measurement.

[0063] Referring to Figure 4 Preferably, the laser sensor assembly 41 comprises three laser sensors arranged in a line, which can effectively reduce the measurement error caused by a single viewing angle and provide more accurate straightness evaluation.

[0064] Referring to Figure 4 In the embodiment, the round bar rotating device 3 comprises a main drive wheel 31, a secondary drive wheel 32, a third lifting assembly 33, a fourth lifting assembly 34 and a third translation assembly 42; the main drive wheel 31 and the secondary drive wheel 32 can be arranged along the first direction, one side of the main drive wheel 31 is connected with a stepping motor, and the stepping motor transmits power to the main drive wheel 31, the third lifting assembly 33 is located below the stepping motor to support the stepping motor and make the stepping motor and the main drive wheel 31 lift, the fourth lifting assembly 34 is located below the secondary drive wheel 32 to support the secondary drive wheel 32 and make the secondary drive wheel 32 lift, the secondary drive wheel 32 is connected with the fourth lifting assembly 34 through a sheet metal part, and the third translation assembly 42 is located below the third lifting assembly 33 and the fourth lifting assembly 34 to support the third lifting assembly 33 and the fourth lifting assembly 34 and translate the third lifting assembly 33 and the fourth lifting assembly 34 along the first direction. The distance between the main drive wheel 31 and the secondary drive wheel 32 can be adjusted by the third translation assembly 42 according to the length of the round bar, so as to ensure good contact and driving effect. After the main drive wheel 31 and the secondary drive wheel 32 contact the round bar, the main drive wheel 31 starts to rotate and drives the round bar to rotate synchronously. The secondary drive wheel 32 serves as auxiliary support to ensure that the round bar remains stable during the entire rotation process.

[0065] Referring to Figure 1 and Figure 5In the embodiment, the sorting device 6 comprises a gripper assembly and a moving module; the gripper assembly comprises a pneumatic mechanical gripper 61 for grabbing the round bar and a fifth lifting assembly 62 for supporting the pneumatic mechanical gripper 61 above the pneumatic mechanical gripper 61 and lifting the pneumatic mechanical gripper 61, the fifth lifting assembly 62 is arranged on the moving module, and the moving module is used to move the fifth lifting assembly 62 in the first direction and the second direction. Optionally, the moving module comprises two fourth translation assemblies 63 for moving the fifth lifting assembly 62 in the second direction and one fifth translation assembly 64 for moving the fifth lifting assembly 62 in the first direction, the fourth translation assembly 63 is arranged above the two fifth translation assemblies 64 and is connected with the fifth translation assembly 64, and the fourth translation assembly 63 moves the pneumatic mechanical gripper and the fifth lifting assembly 62 indirectly by moving the fifth translation assembly 64. The sorting fixing seat 65 supports the fifth translation assembly below the two fifth translation assemblies 64, and the fifth translation assembly 64 comprises a long slide rail which is long enough to extend from the position of the first conveying device 2 to the position of the second conveying device 7, and the structure is as shown in Figure 1 and Figure 5 When it is necessary to grab the round bar, the fifth lifting assembly 62 lifts the pneumatic mechanical gripper 61 to an appropriate height and aligns it with the round bar to be grabbed. Then, the pneumatic mechanical gripper 61 is started, closed and firmly grabs the round bar. After grabbing the round bar, the moving module starts to work and moves the entire fifth lifting assembly 62 and the pneumatic mechanical gripper 61 below it in the first direction and the second direction according to the instruction of the controller. The precise control of the moving module enables the pneumatic mechanical gripper 61 to accurately place the round bar to the designated position, such as the round bar rotating device 3, the roller slide rail 5, the second conveying device 7 or other specific classification areas. The pneumatic mechanical gripper 61 has the function of rotating and can rotate the round bar to be parallel to the first direction or the second direction.

[0066] Please refer to Figure 1 and Figure 5In this embodiment, there are two roller tracks 5, and the two roller tracks 5 are oppositely inclined. The sorting device 6 sorts the round bars according to the analysis results of the controller and places the round bars in corresponding specific positions through the gripper assembly. For example, qualified round bars are placed on the first roller track 5, and due to the inclined arrangement of the roller track, the qualified round bars will automatically roll along the roller track to the collection area. The scrapped round bars are placed on the second roller track 5, and the inclined direction of the roller track is opposite to that of the first roller track, which ensures that the scrapped round bars roll to the collection area on the other side. The round bars that need to be repaired are not directly placed on the roller track 5, but are placed back into the first groove 211 of the inner guide rail 21 of the first conveying device 2 by the sorting device 6 for subsequent processing. By using two roller tracks 5 with opposite inclined directions, the qualified products and the scrapped products are effectively separated, the classification efficiency is improved, and the need for manual intervention is reduced.

[0067] Please refer to Figure 1 In this embodiment, the measuring device further comprises a second conveying device 7 located behind the roller track 5 and below the sorting device 6. When the round bars are conveyed to the end of the second conveying device 7, they will be temporarily stopped there, waiting for the rear-end device to carry them to the next processing step. Preferably, the structure of the second conveying device 7 is the same as that of the first conveying device 2, including the inner guide rail 21, the outer guide rail 22, and the corresponding translation assembly, and the arrangement direction is also the same as that of the first conveying device 2.

[0068] In this embodiment, the translation assembly and the lifting assembly can be used to realize the precise movement of objects such as laser sensors, drive wheels, pneumatic mechanical grippers 61, lifting forks 121, inner guide rails 21, etc. These assemblies can realize their functions in various ways, one common and effective implementation method is to use a cylinder-driven slide rail system, including a linear guide rail, a slide block, and a cylinder. The linear guide rail is fixed, and the slide block moves along the guide rail. The cylinder is connected to the slide block, and the extension and retraction of the cylinder drives the slide block and the load carried by it (such as laser sensors, drive wheels, pneumatic mechanical grippers 61, lifting forks 121, inner guide rails 21, etc.) to move along the guide rail direction. When the controller issues a command, the cylinder starts to inflate or deflate, causing the piston rod to extend or retract. This action causes the slide block to smoothly slide on the linear guide rail, thereby achieving precise translational control of the device assembly mounted thereon. By adjusting the pressure and stroke of the cylinder, the movement distance and speed of the slide block can be accurately controlled. By placing the guide rail in the horizontal direction, the translational movement of the object in the horizontal direction can be realized, and by placing the guide rail in the vertical direction, the lifting movement of the object in the vertical direction can be realized. The cylinder can also be replaced by an oil cylinder. In some cases where manual movement of the object is required, the cylinder can be omitted and only the linear guide rail is retained.

[0070] Step S1: Place the measured round bar in the hopper, adjust the spacing of the hopper according to the length of the round bar, and adjust the lifting fork position of the round bar separation mechanism according to the diameter of the round bar;

[0071] Step S2: The device starts working, the round bar in the hopper is separated one by one, and is carried to the supporting bracket at the end of the round bar separation mechanism through the lifting fork;

[0072] Step S3: The first conveying device moves the round bar from the supporting bracket to the working position of the straightness measuring device and the round bar rotating device through the cyclic action of the second translation assembly and the second lifting assembly;

[0073] Step S4: The round bar rotating device drives the round bar to rotate, the straightness measuring device moves along the axis of the bar to collect straightness information and calculate, according to the straightness, the round bar is divided into three categories: qualified, scrap, and repair, among which the repair type round bar is positioned towards the most bending part and is rotated towards the top;

[0074] Step S5: The sorting device sorts according to the type of the round bar, the round bar is clamped from the round bar rotating device through the jaw assembly, and is placed according to the type of the round bar, among which the qualified type is placed at the first roller slide rail, the scrap type is placed at the second roller slide rail, and the repair type is placed at the guide rail in the first conveying device;

[0075] Step S6: The sorting device transfers the round bar to the second conveying device, the second conveying device conveys the round bar to the end of the second conveying device, and waits for the rear-end device to carry.
