Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and in particular relates to a shifting and transporting mechanism. Background Art

[0002] In product production lines or product inspection lines, a handling mechanism is often used. A handling mechanism is a mechanism that uses a clamp or suction cup to clamp or adsorb the product, and then drives the product from one position to another through a lateral drive module, thereby realizing loading and unloading and transporting the product from one station to another. Since the conveying device and the product storage location of some production lines or the stations are not completely aligned in a straight line, the product needs to be rotated at a certain angle to adjust the product placement angle during the product handling process. In conventional loading and unloading mechanisms, the clamp or suction cup is mainly driven by an independent motor or a rotary cylinder to rotate, which results in a bulky handling mechanism and high manufacturing cost. Utility Model Content

[0003] The utility model aims to provide a displacement transport mechanism to reduce the volume and manufacturing cost of the transport mechanism.

[0004] The described shifting and transporting mechanism includes a mounting plate, on which a bearing seat, a transverse sliding block and a transverse sliding cylinder are mounted, a pull rod is connected to the shaft of the bearing seat, a transverse sliding rail slides in the transverse sliding block, a transverse plate connected to the transverse sliding cylinder is mounted on the transverse sliding rail, the transverse plate is provided with a rotating shaft, a rocker and a clamp / suction cup are fixedly mounted on the rotating shaft, the outer end of the rocker is connected to the other end shaft of the pull rod to form an angle, and the clamp / suction cup is used to clamp or adsorb products.

[0005] According to the technical solution, after the clamp / suction cup clamps or absorbs the product, the transverse cylinder drives the transverse plate to slide on the transverse slider to move the product from one position to another. During the movement of the transverse plate, the pull rod on the bearing seat pulls the outer end of the rocker to limit the outer end of the rocker from moving in the direction of the slide rail, so that when the transverse plate drives the rotating shaft to move, the rocker drives the rotating shaft to move, thereby finally driving the product to rotate; therefore, the utility model achieves the following beneficial effects based on the technical solution:

[0006] 1. When transporting products, it is not necessary to set up independent motors or cylinders to drive the products to rotate and adjust the product placement angle, thereby reducing the volume and manufacturing cost of the shifting and transporting mechanism;

[0007] 2. Compared with the use of motors to drive product rotation, this method can effectively avoid the deviation in the product placement angle caused by the inertia of the product after rotation;

[0008] 3. Since the shifting and transporting mechanism saves the motor or cylinder used to drive the product to rotate, the overall structure is light and simple, which is convenient for the installation, commissioning and maintenance of the equipment.

[0009] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0010] In some embodiments, the displacement and transport mechanism further comprises a frame, the frame is equipped with a lifting rail and a lifting cylinder, the mounting plate is equipped with a lifting slider matched with the lifting rail, and the lifting cylinder is drivingly connected to the mounting plate;

[0011] According to the technical solution, the mounting plate is driven to rise and fall on the lifting rail by the lifting cylinder, so that the clamp / suction cup can stably clamp or adsorb the product and place the product in another position. At the same time, when transporting the product, the mechanism equipment under the clamp / suction cup can be avoided to avoid damage to the product.

[0012] In some embodiments, a lifting limit buffer member that can contact the mounting plate is installed at the end of the lifting slide rail;

[0013] According to the technical solution, the lifting cylinder can more accurately drive the mounting plate down to the set position, so that the clamp / suction cup can accurately contact the product for adsorption or clamping, and at the same time, it can buffer the impact caused by the moment the clamp / suction cup contacts the product.

[0014] In some embodiments, the frame is mounted with a digital pressure sensor connected to the traverse cylinder and the lift cylinder;

[0015] According to the technical solution, when transporting products, the working speed and strength of the transverse cylinder and the lifting cylinder can be stably controlled.

[0016] In some embodiments, a channel connected to the suction cup is provided in the rotating shaft, and the channel is provided with a pneumatic joint located at the top of the rotating shaft and used to connect to the vacuum generator; according to the technical solution, the interference of the pipe connected to the suction cup to the rotation of the rotating shaft can be effectively solved.

[0017] In some embodiments, the rack is equipped with a product placement platform located below the clamp / suction cup, and the product placement platform is equipped with a sensor for sensing the position and orientation of the product, which may be an infrared sensor or a visual system for identifying the contour of the product;

[0018] According to the technical solution, when the clamp / suction cup clamps or absorbs the product, the orientation of the product is identified in advance, thereby ensuring that the product can be perfectly transported from one location and placed in another location.

[0019] In some embodiments, a limit block is installed on the mounting plate, and both ends of the transverse plate are installed with transverse limit buffers that can contact the two side walls of the limit block;

[0020] According to the technical solution, when the transverse cylinder drives the transverse plate to slide on the transverse slider, the product can be accurately moved from above one position to above another position. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings.

[0030] like Figures 1 to 5 As shown, this specific embodiment provides a shifting and transporting mechanism, which includes a frame 1, a mounting plate 2 and a transverse plate 3.

[0031] The frame 1 is equipped with a lifting slide rail 11, a lifting cylinder 12, a lifting limit buffer 13, a digital pressure sensor 14 and a product placement platform 15.

[0032] The mounting plate 2 is equipped with a lifting slider 21 that cooperates with the lifting slide rail 11. The lifting cylinder 12 is transmission-connected to the mounting plate 2. When the lifting cylinder 12 drives the mounting plate 2 to descend to a specific position, the lifting limit buffer 13 can contact the mounting plate 2 to limit the descending position of the mounting plate 2.

[0033] The mounting plate 2 is provided with a bearing seat 22, a traverse slider 24, a traverse cylinder 23 and a limit block 25, and the bearing seat 22 is axially connected with a pull rod 26. The traverse plate 3 is provided with a traverse rail 31 matched with the traverse slider 24, and the traverse cylinder 23 drives the traverse plate 3 to move laterally.

[0034] The traverse plate 3 is provided with a rotating shaft 32, on which a rocker 34 and a clamp / suction cup 33 (the suction cup 33 is used as an example below) are fixedly mounted. The outer end of the rocker 34 is connected to the other end of the pull rod 26 and forms an angle. The suction cup 33 is used to absorb the product. The suction cup 33 is located at the lower end of the rotating shaft 32. A channel connected to the suction cup 33 is provided in the rotating shaft 32. The channel is provided with a pneumatic joint 35 located at the top of the rotating shaft 32 and used to connect to the vacuum generator. The two ends of the shifting plate are equipped with traverse limit buffers 36 that can contact the two side walls of the limit block 25. The frame 1 is equipped with a digital pressure sensor 14 connected to the traverse cylinder 23 and the lifting cylinder 12.

[0035] The product placement platform 15 is located below the suction cup 33 . The product placement platform 15 is equipped with a sensor 16 for sensing the position and orientation of the product. The sensor 16 may be an infrared sensor 16 or a visual system for identifying the contour of the product.

[0036] The following is a working process of a shifting and transporting mechanism described in this specific implementation mode:

[0037] The lifting cylinder 12 drives the mounting plate 2 to descend on the lifting rail 11, so that the suction cup 33 contacts the product on the product placement platform 15 and adsorbs the product; thereafter, the lifting cylinder 12 drives the mounting plate 2 to ascend and reset on the lifting rail 11, and the transverse cylinder 23 drives the transverse plate 3 to slide on the transverse slider 24, so that the product is moved from above the product placement platform 15 to above another position. During the movement of the transverse plate 3, the pull rod 26 on the bearing seat 22 pulls the outer end of the rocker 34 to limit The outer end of the rocker arm 34 moves in the direction of the slide rail, so that when the transverse plate 3 drives the rotating shaft 32 to move, the rocker arm 34 drives the rotating shaft 32 to move, and finally drives the product to rotate; thereafter, the lifting cylinder 12 drives the mounting plate 2 to descend again on the lifting slide rail 11 to place the product in another position. At this time, the suction cup 33 stops adsorbing the product, and then the lifting cylinder 12 drives the mounting plate 2 to rise and reset on the lifting slide rail 11, and the transverse cylinder 23 drives the transverse plate 3 to slide in the opposite direction on the transverse slider 24 to reset.
