TECHNICAL FIELD

[0001] The application relates to the technical field of grabbing devices, in particular to an ECU automatic picking mechanism. BACKGROUND

[0002] In an automobile steer-by-wire system, an electronic controller ECU is a very important electronic product element. The electronic controller ECU is a micro computer management center, which takes signal collection, calculation processing, analysis judgment and decision countermeasure as input, and then takes issuing of control instructions and commanding of actuator work as output.

[0003] In order to prevent damage of the ECU caused by external environment, the ECU usually needs to be quickly transferred into a turnover box for storage and transportation after processing. At present, the picking and placing of the ECU mainly adopts two ways, one is manual grabbing, and the other is precise mechanical hand grabbing.

[0004] The manual grabbing way has human deviation, and is prone to cause abrasion and bumping of the ECU in the process of grabbing and placing, which not only damages the product quality but also is time-consuming and laborious. Although the precise mechanical hand grabbing way can realize precise grabbing and transportation, the precise mechanical hand is expensive, which increases the enterprise cost.

[0010] By adopting the technical scheme, the rotating motor drives the lead screw to rotate, and the threaded connection between the lead screw and the mounting seat enables the mounting seat to move up and down as needed, so as to adjust the height position of the clamping assembly to adapt to the ECU picking requirements of different sizes or heights; this design not only improves the flexibility and automation degree of the equipment, but also ensures the stability and accuracy during operation, realizes the accurate movement of the mounting seat in the vertical direction, and ensures the accuracy of ECU picking.

[0011] Optionally, the clamping assembly includes a first clamping rod, a second clamping rod and a driving member, the top ends of the first clamping rod and the second clamping rod are connected to the mounting seat in a horizontal rotating manner, and the bottom ends of the first clamping rod and the second clamping rod are provided with clamping blocks; the driving member is arranged on the mounting seat, and the driving member is used for synchronously driving the bottom ends of the first clamping rod and the second clamping rod to move close to or away from each other.

The structural design makes the clamping force uniformly distributed, avoiding the risk of ECU damage caused by unilateral force. In addition, the gears and the racks are arranged to make the driving component synchronously drive the bottom ends of the first clamping rod and the second clamping rod to approach or move away from each other without the need for additional power source.

DETAILED DESCRIPTION

[0030] The following will be described in detail with reference to the accompanying drawings Figures 1-3 The application is further described in detail.

[0031] The embodiment of the application discloses an ECU automatic picking mechanism. Figure 1 The ECU automatic picking mechanism comprises a support 1, a first moving seat 2, a second moving seat 3, a mounting seat 4 and a clamping assembly 5. The support 1 can be a rigid structure fixed on the ground or other supporting surface, and is used for providing basic support. The first moving seat 2 is slidably connected to the support 1 in the transverse direction, and the support 1 is provided with a first driving part 6 used for driving the first moving seat 2 to move. The second moving seat 3 is slidably connected to the first moving seat 2 in the transverse direction, and the moving direction of the second moving seat 3 is perpendicular to that of the first moving seat 2, and the first moving seat 2 is provided with a second driving part 7 used for driving the second moving seat 3 to move. The mounting seat 4 is slidably connected to the second moving seat 3 in the vertical direction, and the second moving seat 3 is provided with a third driving part 8 used for driving the mounting seat 4 to move up and down. The clamping assembly 5 is arranged on the mounting seat 4, and the clamping assembly 5 is used for clamping the ECU.

[0032] In use, according to the position of the ECU to be picked up, the first moving seat 2 and the second moving seat 3 are driven to move correspondingly by cooperation of the first driving part 6 and the second driving part 7, so that the clamping assembly 5 on the mounting seat 4 is located directly above the ECU to be picked up, and then the mounting seat 4 is driven to move downward by the third driving part 8, and when the clamping assembly 5 approaches the ECU, the ECU is accurately and stably clamped by the clamping assembly 5. Compared with manual picking, there is no human deviation, and the accuracy is higher; compared with picking by a precision manipulator, the structure is simpler, the cost is lower, the enterprise cost is saved, and the problem that the manual grabbing mode has human deviation and the precision manipulator is expensive and increases the enterprise cost is improved.

[0033] The first driving member 6 comprises a guide rail 61, a threaded rod 62 and a servo motor 63. The guide rail 61 is fixedly installed on the support 1 in the transverse direction, and the first moving seat 2 is slidingly arranged on the guide rail 61. The threaded rod 62 is threadedly connected to the guide rail 61 in the length direction of the guide rail 61, and penetrates through the first moving seat 2 and is threadedly connected with the first moving seat 2. The servo motor 63 is fixedly connected to the end of the guide rail 61, and the rotating shaft of the servo motor 63 is coaxially connected with the threaded rod 62. The rotation of the servo motor 63 drives the threaded rod 62 to rotate, thereby driving the first moving seat 2 to move in the length direction of the threaded rod 62. The second driving member 7 has the same structure as the first driving member 6. The threaded rod 62 in the second driving member 7 penetrates through the second moving seat 3 and is threadedly connected with the second moving seat 3. In other embodiments, the first driving member 6 and the second driving member 7 can also be air cylinders or hydraulic cylinders. The output ends of the air cylinders or the hydraulic cylinders are directly fixedly connected with the first moving seat 2 or the second moving seat 3. The rapid movement of the output ends of the air cylinders or the hydraulic cylinders realizes the rapid change of the positions of the first moving seat 2 or the second moving seat 3.

[0034] Further, referring to Figures 1-2 The second moving seat 3 is provided with a guide strip 31 in the vertical direction. The width of the guide strip 31 close to the second moving seat 3 is smaller than the width of the guide strip 31 away from the second moving seat 3. The mounting seat 4 is provided with a clamping groove 41 in the vertical direction, which is matched with the shape of the guide strip 31. The mounting seat 4 is slidingly arranged on the guide strip 31 through the clamping groove 41. The third driving member 8 comprises a lead screw 81 and a rotating motor 82. The rotating motor 82 is fixedly installed on the top of the second moving seat 3 in the vertical direction, and the lead screw 81 is coaxially connected with the rotating shaft of the rotating motor 82. The mounting seat 4 is integrally formed with a sliding block 42 on the inner side. The lead screw 81 penetrates through the sliding block 42 and is threadedly connected with the sliding block 42. The rotation of the rotating motor 82 drives the lead screw 81 to rotate, so that the sliding block 42 has a tendency to rotate with the lead screw 81. However, the mounting seat 4 cannot rotate because it is slidingly arranged on the guide strip 31 through the clamping groove 41. Therefore, the rotation of the lead screw 81 can drive the mounting seat 4 to move in the vertical direction, thereby realizing the function of driving the mounting seat 4 to move up and down. The threaded connection between the lead screw 81 and the sliding block 42 can drive the sliding block 42 to move more stably and reliably, and has higher precision.

[0035] The clamping assembly 5 comprises a first clamping rod 51, a second clamping rod 52 and a driving component. The first rotating rod 53 and the second rotating rod 54 are arranged on the mounting seat 4 in a transverse direction, and are parallel to the threaded rod 62 in the first driving member 6. The first rotating rod 53 and the second rotating rod 54 can rotate around their own axes, and the outer wall of the first rotating rod 53 and the second rotating rod 54 is provided with external threads. The first clamping rod 51 is sleeved on the first rotating rod 53, and the first rotating rod 53 is provided with two fixed nuts 55 which are screwed with the first rotating rod 53. The first clamping rod 51 is fixed on the first rotating rod 53 by tightening the two fixed nuts 55. The second clamping rod 52 is sleeved on the second rotating rod 54, and the second rotating rod 54 is also provided with two fixed nuts 55 which are screwed with the second rotating rod 54. The bottom ends of the first clamping rod 51 and the second clamping rod 52 are provided with clamping blocks 9. The driving component is arranged on the mounting seat 4, and is used for synchronously driving the first rotating rod 53 and the second rotating rod 54 to rotate in opposite directions, so as to drive the bottom ends of the first clamping rod 51 and the second clamping rod 52 to move close to or away from each other.

[0036] Under the action of the driving component, the first clamping rod 51 and the second clamping rod 52 can realize opening and closing actions, so that the two clamping blocks 9 move close to or away from each other, thereby accurately clamping and releasing the ECU. This design not only improves the clamping accuracy, ensures the stability and reliability of the operation, but also can adapt to the picking of ECU of different sizes, and the structure is simple and practical.

[0037] Specifically, the driving component comprises two sets of gears 56 and two sets of racks 57. The two gears 56 are coaxially connected to the first rotating rod 53 and the second rotating rod 54 respectively, and the two racks 57 are fixedly connected to the middle part of the second moving seat 3 in a vertical direction. The two racks 57 are arranged on the left and right sides of the lead screw 81 in a transverse direction, and the gears 56 and the racks 57 on the same side of the lead screw 81 are engaged. During the downward movement of the mounting seat 4, the gears 56 are driven to move downward. Since the gears 56 are engaged with the racks 57, the gears 56 will rotate during the downward movement, thereby driving the first rotating rod 53 and the second rotating rod 54 to rotate in opposite directions. The arrangement of the driving component makes the rotation of the first clamping rod 51 and the second clamping rod 52 not need an additional power source, thereby saving power cost.

[0038] Further, with reference to Figure 1 and Figure 3The clamping blocks 9 are made of elastic material, and are rotatably connected to the first clamping rod 51 or the second clamping rod 52 in the transverse direction. A limiting block 91 is arranged on the top of the clamping block 9. When the ECU is clamped, once the two clamping blocks 9 tightly adhere to the corresponding side walls of the ECU, the limiting block 91 touches the side of the corresponding clamping rod, preventing the clamping from failing due to excessive rotation of the clamping block 9. The design of the clamping block 9 increases the clamping area, making the clamping more stable.

[0039] In addition, the side of the two clamping blocks 9 close to each other is also equipped with a buffer block 92. A first through hole 921 is drilled in the buffer block 92, and a second through hole 93 is reserved on the clamping block 9. An adjusting bolt 94 is inserted into the first through hole 921, and the threaded rod of the adjusting bolt 94 penetrates through the second through hole 93. Finally, the threaded part of the adjusting bolt 94 is screwed into an adjusting nut 95 arranged on the side of the clamping block 9 away from the buffer block 92 to be fixed. At the same time, a buffer spring 10 is connected between the buffer block 92 and the clamping block 9. The buffer spring 10 tends to offset the buffer block 92 from the clamping block 9 by a certain distance, thereby providing a proper amount of elasticity during the entire clamping process, avoiding physical damage to sensitive objects.

[0040] The implementation principle of the ECU automatic picking mechanism of the embodiment is as follows: in use, according to the position of the ECU to be picked, the first moving seat 2 and the second moving seat 3 are driven to move correspondingly by the cooperation of the first driving member 6 and the second driving member 7, so that the clamping assembly 5 on the mounting seat 4 is located directly above the ECU to be picked. Then the rotating motor 82 is started to drive the lead screw 81 to rotate, thereby driving the mounting seat 4 to move downward and gradually approach the ECU to be picked. During the downward movement of the mounting seat 4, the first rotating rod 53 and the second rotating rod 54 are driven to rotate in opposite directions due to the meshing of the gear 56 and the rack 57, thereby driving the first clamping rod 51 and the second clamping rod 52 to move closer to each other at the bottom, until the buffer plate on the clamping block 9 is clamped on both sides of the ECU, realizing stable clamping and picking of the ECU. Compared with manual picking, there is no human error, and the accuracy is higher. Compared with picking by a precision mechanical hand, the structure is simpler, the cost is lower, the enterprise cost is saved, and the problem of human error in the manual grabbing mode is improved, and the cost of the precision mechanical hand is high, which increases the enterprise cost.

[0041] The above are optional embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made in the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
