Description

Technical Field

[0001] The utility model relates to the technical field of automatic conveying equipment, in particular to an adaptive centering adjustment mechanism. Background Technique

[0002] With the continuous increase of labor costs in manufacturing enterprises and the continuous development of intelligent manufacturing, intelligent transmission equipment is more and more applied to the fields of production manufacturing and warehousing management.

[0003] However, no matter what kind of transmission equipment, it is necessary to center and position the product on the transmission equipment during packaging, sorting, inspection and other requirements. The traditional centering and positioning function often needs to be realized by manipulators, mechanical grippers or beveled edges. However, the above methods often require the product to have a fixed external dimension or a fixed notch that can be clamped. Otherwise, it is impossible to mix and transport products with different external dimensions, or it is necessary to frequently adjust various parameters to realize the centering and positioning function, which is extremely cumbersome for diverse flexible production and brings great inconvenience to the production factory. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects, provide an adaptive centering adjustment mechanism, which can be used in cooperation with most existing transmission equipment, can adaptively center and position different product external dimensions, and can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an adaptive centering adjustment mechanism, including a frame, two corresponding linear slide rails are installed on the left and right sides inside the frame, two corresponding movable centering clamping blocks are installed on four sliding blocks arranged at the front and rear ends on the upper sides of the two linear slide rails, two corresponding sprocket and chain structures are installed on the left and right sides inside the frame, the chain in the left sprocket and chain structure is connected to the left rear sliding block, the chain in the right sprocket and chain structure is connected to the right front sliding block, two corresponding drive motors are installed at the lower ends on the left and right sides inside the frame, the output shafts of the drive motors are respectively fixed on the end faces of two sprockets at the rear sides of the two sprocket and chain structures, a uniformly distributed sensing component is installed on the upper side of the movable centering clamping block, and the input end of the drive motor is electrically connected to the output end of an external PLC controller. By setting two sprocket and chain structures, the front and rear movable centering clamping blocks are driven to approach.

[0006] Further, the sensing assembly includes a pressure head, a mounting frame, and a sensor. Uniformly distributed mounting frames are fixed to the upper side of the movable centering clamp block. A pressure head is further connected inside the mounting frame. A spring is sleeved on the surface of the pressure head. One end of the spring is fixed to the inner side wall of the mounting frame, and the other end of the spring is fixed to the circular surface of the pressure head. A sensor is mounted on the side of the mounting frame. The sensor cooperates with the pressure head, and the sensor is bidirectionally electrically connected to an external PLC controller. By setting the sensing assembly, the position of the articles inside the rack can be effectively sensed.

[0007] Further, uniformly distributed support rods are fixed to the lower side of the rack, and a bottom plate is fixed to the lower side of the support rods. The rack is supported by setting the support rods and the bottom plate.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: By setting the driving motor to control the movement of the sprocket and chain structure to drive the two movable centering clamp blocks to perform centering movement along the linear slide rail, the articles located on the rack can be centered and positioned in this way, which is extremely fast. During the whole process, the centering positioning operation can be adapted to different product shapes and sizes, which is extremely convenient. Description of the Drawings

[0012] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0013] Please refer to Figure 1-2, this embodiment provides an adaptive centering adjustment mechanism, including a frame 1. On the left and right sides inside the frame 1, two corresponding linear sliding rails 5 are installed. Four sliding blocks arranged at the front and rear ends on the upper sides of the two linear sliding rails 5 are provided with two corresponding movable centering clamping blocks 2. On the left and right sides inside the frame 1, two corresponding sprocket and chain structures 4 are installed. The chain in the left sprocket and chain structure 4 is connected to the sliding block at the rear end on the left side, and the chain in the right sprocket and chain structure 4 is connected to the sliding block at the front end on the right side. At the lower ends of the left and right sides inside the frame 1, two corresponding driving motors 3 are installed. The output shafts of the driving motors 3 are respectively fixed on the end faces of two sprockets at the rear sides of the two sprocket and chain structures 4. On the upper side of the movable centering clamping block 2, a uniformly distributed sensing assembly 7 is installed. The input end of the driving motor 3 is electrically connected to the output end of an external PLC controller. The sensing assembly 7 includes a pressure head 71, a mounting frame 72, and a sensor 73. On the upper side of the movable centering clamping block 2, uniformly distributed mounting frames 72 are fixed. Inside the mounting frame 72, a pressure head 71 is further connected. The surface of the pressure head 71 is sleeved with a spring. One end of the spring is fixed on the inner side wall of the mounting frame 72, and the other end of the spring is fixed on the circular surface of the pressure head 71. On the side of the mounting frame 72, a sensor 72 is installed. The sensor 72 cooperates with the pressure head 71. The sensor 72 is bidirectionally electrically connected to the external PLC controller. By setting the sensing assembly 7, the position of the articles inside the frame 1 can be effectively sensed. By setting two sprocket and chain structures 4, the front and rear two movable centering clamping blocks 2 can be driven to approach each other.

[0014] Among them: uniformly distributed support rods 8 are fixed on the lower side of the frame 1, and a bottom plate 6 is fixed on the lower side of the support rods 8. By setting the support rods 8 and the bottom plate 6, the frame 1 is supported.

[0015] The working principle of the present utility model is as follows:

[0016] When in use, place the article on the frame 1, and then start the two driving motors 3 to drive the two chains in the sprocket and chain structure 4 to rotate. During the rotation process, the front and rear two movable centering clamping blocks 2 can be driven to move centering along the linear sliding rails 5. After the pressure head 71 in the sensing assembly 7 contacts the product, it continues to clamp inward. When the clamping force is greater than the tension of the spring 9 inside the mounting frame 72, the pressure head 71 moves backward until the sensor 73 is triggered. When all 4 sensors are triggered, the motor stops working. At this time, the centering positioning of the article can be completed, which is extremely convenient.

[0017] The above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
