Description

Technical Field

[0001] The present application relates to the technical field of automobile parts manufacturing, and in particular to a high-precision automatic positioning device for automobile parts. Background Art

[0002] The automobile parts production line is a vital component of the automobile manufacturing industry, which involves the entire production process from raw material processing to parts assembly. The automobile parts production line usually includes raw material processing, parts manufacturing, assembly and testing, automation and robotics, logistics and warehousing, and information and intelligence. The efficient operation of the automobile parts production line is crucial to automobile manufacturers, directly affecting the production cost, quality and delivery time of the automobile.

[0003] In the prior art, after cutting, plates of the same type in automotive parts will accumulate and pile up together, and then the plates will be adsorbed by the strong electromagnetic suction of the robot arm. As the robot arm rotates, the plates will be synchronously transferred to the next processing operation platform, so as to facilitate further processing of the plates transferred to the processing operation platform.

[0004] In order to improve the efficiency of the robot in transferring plates, the robot usually drops from a fixed point. It is difficult to ensure the neatness of a large number of piled plates. The robot that drops from a fixed point directly magnetically attracts the plates with inaccurate positions and transfers them to the next processing operation platform, which will increase the workload of the processing operation platform to further correct and position the plates. Even if the plates are stacked and placed neatly, the plates are easily offset and misplaced due to the magnetic collision of the robot, which will cause the robot to absorb the plates and the position of the plates is inaccurate, thereby reducing the work efficiency of auto parts production. Utility Model Content

[0005] In order to improve the work efficiency of auto parts production, the present application provides a high-precision automated positioning device for auto parts.

[0006] The present application provides a high-precision automatic positioning device for auto parts, which adopts the following technical solutions:

[0007] A high-precision automated positioning device for auto parts comprises an inclined support platform and legs supporting the support platform, wherein one leg is provided at each of the four corners corresponding to the bottom of the support platform, a baffle is provided along the length direction of the edge of the support platform which is inclined downward, a limiting block is provided at the corner position of the support platform corresponding to the plate away from the baffle, and a limiting groove is provided on the limiting block corresponding to the corner of the baffle, when the plate is placed on the support platform, the side wall of the plate contacts the baffle, and the corner of the plate away from the baffle is inserted into the limiting groove and plugged into and matched with the limiting groove.

[0008] By adopting the above technical solution, before the manipulator transfers the plate, the plate is first placed on the support platform. Since the support platform is inclined, the plate slides along the inclined direction of the support platform due to its own center of gravity until the side wall of the plate hits the side wall of the baffle bar, and the corner away from the baffle bar is inserted into the limit groove. The inclined setting of the limit block, baffle bar and support platform not only ensures the accurate and stable positioning of the plate, but also facilitates the subsequent transfer operation of the manipulator, reduces the workload of correcting the positioning, and thus improves the work efficiency of auto parts production.

[0009] Optionally, each of the legs includes a hydraulic cylinder and a ball hinge arranged at the top end of the hydraulic cylinder piston rod, the hydraulic cylinder is vertically arranged with its piston rod extending upward, and the ball hinge is installed between the top end of the piston rod and the top wall of the support platform.

[0010] By adopting the above technical solution, the hydraulic cylinder can adjust the tilt angle of the pedestal, and the ball hinge provides a flexible connection between the pedestal and the hydraulic cylinder piston rod. This structure allows the pedestal to provide a suitable tilt angle for plates of different models and weights, thereby improving the flexibility and applicability of the positioning device.

[0011] Optionally, one limit block is provided for each type of plate, and the limit groove on each limit block is matched with the corresponding corner of the plate. A fixed plate is provided parallel to the bottom of the support platform, and an electric pusher is provided on the fixed plate perpendicular to the table surface of the support platform corresponding to each limit block. A through hole is opened on the support platform corresponding to each limit block, and the limit block slides through the corresponding through hole under the push of the electric pusher.

[0012] By adopting the above technical solution, each limit block corresponding to different types of plates is equipped with an electric pusher, which can be extended and retracted on the fixed plate perpendicular to the base surface. When the customized plate covers the limit groove, the corresponding electric pusher is driven to work, and the electric pusher pushes the limit block to extend until the corner of the customized plate is completely inserted into the limit groove, which can further improve the positioning effect of different plates, thereby improving production efficiency.

[0013] Optionally, a placement groove is provided in each of the limit blocks and connected to the limit groove, and a proximity switch electrically connected to the corresponding electric push member is provided in the placement groove. When the proximity switch senses that the plate covers the top of the limit groove, it drives the electric push member to push the limit block to extend from the through hole until the corner of the plate is inserted into the limit groove.

[0014] By adopting the above technical solution, the proximity switch corresponding to the plate model senses the corresponding plate, and the corresponding electric pusher receives the electrical signal transmitted by the proximity switch and pushes the limit block to extend until the corner of the plate of this model is fully inserted into the limit groove. This automated positioning method further improves production efficiency.

[0015] Optionally, each of the limiting blocks has a chamfered side wall facing the limiting groove.

[0016] By adopting the above technical solution, the chamfered design makes the corner of the plate smoother when inserted into the limit groove, reduces the resistance during the insertion process, and improves the positioning speed and accuracy. This improvement solution can effectively improve the performance of the device without increasing the manufacturing cost.

[0017] Optionally, a plurality of universal balls are laid on the plane of the support platform, and the plurality of universal balls all pass through the plane of the support platform and are installed on the plane of the support platform through flanges.

[0018] By adopting the above technical solution, the design of the universal ball effectively reduces the friction between the plate and the support, ensuring that the plate can slide down smoothly to the positioning position. This not only improves the accuracy of positioning, but also reduces the friction damage that may occur during the transfer process.

[0019] Optionally, a foot seat is provided at the bottom of the cylinder body of each hydraulic cylinder.

[0020] By adopting the above technical solution, the design of the foot enhances the stability and load-bearing capacity of the positioning device, ensuring that the positioning device can operate stably during operation without causing a decrease in positioning accuracy or damage to the positioning device due to external factors.

[0021] Optionally, a support rod is connected between the cylinder bodies of two adjacent hydraulic cylinders, and reinforcing ribs are provided at the connections between the support rods and between the support rods and the hydraulic cylinder bodies.

[0022] By adopting the above technical solution, support rods connect the cylinder bodies of adjacent hydraulic cylinders, so that a stable support structure can be formed between multiple hydraulic cylinders, and reinforcing ribs are arranged at the connections between support rods and support rods, and between support rods and hydraulic cylinder bodies. The reinforcing ribs increase the connection area and disperse stress, thereby effectively improving the structural strength and bearing capacity of the overall positioning device.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Before the robot transfers the plate, place the plate on the support platform. Since the support platform is tilted, the plate slides along the tilt direction of the support platform due to its own center of gravity until the side wall of the plate hits the side wall of the baffle bar, and the corner away from the baffle bar is inserted into the limit groove. The tilt setting of the limit block, baffle bar and support platform not only ensures the accurate and stable positioning of the plate, but also facilitates the subsequent transfer operation of the robot, reduces the workload of correction and positioning, and thus improves the work efficiency of auto parts production;

[0025] 2. The hydraulic cylinder can adjust the tilt angle of the cap, while the ball hinge provides a flexible connection between the cap and the hydraulic cylinder piston rod. This structure allows the cap to provide a suitable tilt angle for plates of different models and weights, thereby improving the flexibility and applicability of the positioning device;

[0026] 3. Each limit block corresponding to different types of plates is equipped with an electric pusher, which can be extended and retracted on the fixed plate perpendicular to the base surface. When the customized plate covers the limit groove, the corresponding electric pusher is driven to work, and the electric pusher pushes the limit block out until the corner of the customized plate is completely inserted into the limit groove, which can further improve the positioning effect of different plates, thereby improving production efficiency.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a high-precision automatic positioning device for auto parts.

[0034] Reference Figure 1 A high-precision automatic positioning device for auto parts includes a base 1 and four legs 2 supporting the base 1. The four legs 2 correspond to the four corners of the bottom of the base 1 respectively. The base 1 is inclined. At two adjacent edges of the base 1 that are inclined downward, a baffle 3 is fixedly arranged along the length direction of the corresponding edge. The baffle 3 is used to limit the position of a plate 01 placed on the base 1, so that the plate 01 can contact the side wall of the baffle 3 during the sliding process, thereby positioning the adjacent two sides of the plate 01.

[0035] Reference Figure 1 and Figure 2 , a limiting block 4 is provided on the support platform 1 corresponding to the corner position of the plate 01 away from the stop bar 3, and one limiting block 4 is provided corresponding to various types of plates 01, and a limiting groove 41 is provided on the limiting block 4 at the corner position corresponding to the stop bar 3, and the limiting groove 41 on each limiting block 4 is matched with the corresponding corner of the plate 01, and a chamfer 42 is provided on the side wall of each limiting block 4 facing the limiting groove 41. When the customized plate 01 is placed on the support platform 1 and slides down the inclined plane, its corner away from the stop bar 3 can be inserted into the limiting groove 41, thereby realizing the precise positioning of the other side of the plate 01.

[0036] Reference Figure 1 and Figure 3 A fixing plate 5 parallel to the platform 1 is installed at the bottom of the platform 1, and a through hole 11 is opened on the platform 1 corresponding to each limit block 4. An electric pusher 6 is arranged on the fixing plate 5 corresponding to each limit block 4 perpendicular to the table surface of the platform 1. The electric pusher 6 of this embodiment takes the cylinder 61 as an example. The cylinder 61 is perpendicular to the table surface of the platform 1, and the bottom wall of the cylinder body is fixedly set on the fixing plate 5. The top end of the piston rod of the cylinder 61 is fixedly set on the bottom wall of the limit block 4. The limit block 4 slides and passes through the corresponding through hole 11 under the push of the piston rod of the cylinder 61.

[0037] Reference Figure 1 and Figure 2 Each limiting block 4 is also connected to the limiting groove 41 and has a placement groove 43 , and each placement groove 43 is fixedly provided with a proximity switch 7 electrically connected to the corresponding cylinder 61 .

[0038] Reference Figure 1 and Figure 2 When the proximity switch 7 senses that the plate 01 covers the upper portion of the limiting groove 41 , the cylinder 61 is driven to push the limiting block 4 out of the through hole 11 until the corner of the plate 01 is accurately inserted into the limiting groove 41 due to gravity.

[0039] Reference Figure 3 Each leg 2 includes a hydraulic cylinder 21 and a ball hinge 22. Each hydraulic cylinder 21 is vertically arranged with its piston rod extending upward. The ball hinge 22 is installed between the top of the piston rod and the top wall of the support platform 1, so that the angle of the support platform 1 can be adjusted by the hydraulic cylinder 21, so as to adapt to the processing requirements and positioning accuracy of different types of plates 01, providing higher production flexibility.

[0040] Reference Figure 1 and Figure 3In order to further enhance the stability and load-bearing capacity of the entire device, a foot seat 211 is installed at the bottom of each hydraulic cylinder 21. At the same time, in order to prevent the device from shaking when moving or carrying heavy objects, a support rod 8 is fixedly connected between the cylinder bodies of two adjacent hydraulic cylinders 21 to enhance the overall structural stability. Furthermore, a reinforcing rib 81 is added to the connection between the support rod 8 and the cylinder body of the hydraulic cylinder 21, which further improves the mechanical strength and service life of the device.

[0041] Reference Figure 1 In order to reduce the friction between the plate 01 and the surface of the base 1 and ensure that the plate 01 can slide down the inclined plane more smoothly, a number of universal balls 9 are specially laid on the plane of the base 1. These universal balls 9 not only pass through the plane of the base 1, but are also firmly installed on the plane of the base 1 through flanges.

[0042] The implementation principle of a high-precision automated positioning device for auto parts in an embodiment of the present application is as follows: before the robot transfers the plate 01, firstly, the inclination angle of the base 1 is adjusted by the hydraulic cylinder 21 according to production requirements or changes in the model of the plate 01, so as to achieve optimal positioning and processing preparation state for plates 01 of different models.

[0043] Then the worker or automated equipment places the plate 01 to be processed on the inclined support platform 1. Since the support platform 1 is inclined, the plate 01 will automatically slide down along the slope; during the sliding process, the adjacent two sides of the plate 01 respectively contact the corresponding blocking bars 3 for preliminary positioning. At the same time, when the corner on the other side of the plate 01 slides down to the position of the limit block 4, it will be sensed by the proximity switch 7; once the proximity switch 7 senses the arrival of the plate 01, it transmits the signal to the control system, and the control system immediately drives the corresponding electric pusher 6 to push the limit block 4 out until the corner of the plate 01 is inserted into the limit groove 41 to complete the precise positioning; at this time, the robot can transfer the positioned plate 01 through strong magnetic suction.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
