Description

Technical Field

[0001] The utility model relates to the field of factory material transfer systems, and particularly to a locking system for a material turnover device. Background Art

[0002] During the production process of the metal casings of 3C digital products, multiple steps such as blanking, cutting, sandblasting, anodizing, and dyeing are required. Therefore, a material turnover device is needed to transport materials between different production stations. Regarding this problem, the applicant has applied for a Chinese utility model patent with the publication number CN 219728395 U. The solution in this application mainly includes fixed piles and turnover frames, where the turnover frames are transported by AGV carts and transferred between different fixed piles. The turnover frames are fixed to the fixed piles by positioning cylinders, as shown in the attached drawings of CN 219728395 U. Figure 1 as shown.

[0003] However, in actual use, it is found that the positioning cylinders are severely worn, prone to air leakage and damage, and need to be frequently replaced. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problem that the locking cylinders of the existing material turnover devices are easily worn and damaged, and to provide a locking system for a material turnover device, which includes fixed piles fixed on the ground and turnover frames moving between different fixed piles, and the locking system is installed to lock the turnover frames to the fixed piles.

[0005] The locking system includes a chute opened along the direction of the turnover frame entering and exiting the fixed pile, a block is slidably arranged in the chute, a driving cylinder is installed on the fixed pile, and the driving cylinder drives the block to move along the chute; the turnover frame is provided with a slot that cooperates with the block, and the block is inserted into the slot to press the turnover frame tightly against the fixed pile.

[0006] One end of the chute near the direction of the turnover frame entering and exiting is provided with a curved arc portion, and the curved arc portion of the chute bends away from the slot; when the block enters the curved arc portion, the slider is disengaged from the slot.

[0007] In some embodiments, the fixed pile is provided with a blocking structure, and the turnover frame abuts against the blocking structure of the fixed pile.

[0008] In some embodiments, the fixed pile includes two left and right legs, and a gap for the AGV cart to pass through is reserved between the two legs; the locking systems are respectively arranged on the left and right legs of the fixed pile.

[0009] In some embodiments, the legs are provided with rotating shafts, and the driving cylinders are rotatably installed on the rotating shafts.

[0010] In some embodiments, the stopper includes a sliding portion, a connecting portion, and a blocking portion. The sliding portion is embedded in the chute and slides along the chute.

[0011] The two ends of the connecting portion are respectively connected to the sliding portion and the blocking portion, and the connecting portion is connected to the driving rod of the driving cylinder.

[0012] The blocking portion extends toward the chute and is inserted into the chute, abutting against the end of the chute to tightly press the turnover rack.

[0013] In some embodiments, the sliding portion extends along the direction of the chute, and the cross-section of the sliding portion is smaller than the cross-section of the chute; a gap is reserved between the sliding portion and the inner wall of the chute.

[0014] In some embodiments, the driving cylinder is arranged parallel to the direction in which the turnover rack enters and exits the fixed pile.

[0015] Applying the above technical solution of the present utility model has the following effects:

[0016] As Figure 1 shown in, in the prior art, the locking mechanism on the fixed pile pulls the turnover rack forward toward the fixed pile. During the locking process, continuous force is applied to the turnover rack. However, the driving direction of the locking cylinder of the locking mechanism in the prior art is perpendicular to the force application direction. Therefore, during the locking process, the turnover rack will continuously apply a radial force to the cylinder rod of the driving cylinder, resulting in continuous extrusion and wear on the side of the driving cylinder facing the rear of the turnover rack. This causes the driving cylinder to malfunction.

[0017] In this application, the setting method of the locking device is modified so that the driving cylinder is only subjected to an axial force during the locking process, which conforms to the ideal usage situation of the driving cylinder.

[0018] Specifically, a driving cylinder is used to drive a stopper sliding in the chute, and the stopper is used to engage with the card slot of the turnover rack. At this time, the driving cylinder applies force to lock the turnover rack to the fixed pile. At the same time, one end (the rear end) of the chute close to the direction in which the turnover rack enters and exits has an arc portion. When the stopper moves to the arc portion at the rear end of the chute, the stopper will disengage from the card slot, thereby releasing the turnover rack. At this time, the turnover rack will be carried by the AGV cart to other workstations.

[0019] Other features and advantages of the present utility model will be described in detail in the subsequent specific embodiment part. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following details the specific implementation mode of the present utility model. It should be understood that the specific implementation mode described herein is only for explaining and interpreting the present utility model and is not used to limit the present utility model.

[0031] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower" generally refer to the orientation in the assembled and used state. "Inner, outer" refer to the inner and outer of the contour of each component itself. "Front, back" means that the direction in which the turntable frame 2 enters the fixed pile 1 is "front" and the direction in which it leaves the turntable frame 2 is "back".

[0032] In the present utility model, a locking system for a material turnover device is provided. The locking system of the material turnover device includes a fixed pile 1 fixed on the ground and a turntable frame 2 moving between different fixed piles 1. The locking system is installed to lock the turntable frame 2 to the fixed pile 1.

[0033] The locking system includes a slide groove 3 opened along the direction in which the turntable frame 2 enters and exits the fixed pile 1. A stopper 4 is slidably arranged in the slide groove 3. A driving cylinder 6 is installed on the fixed pile 1, and the driving cylinder 6 drives the stopper 4 to move along the slide groove 3; the turntable frame 2 is provided with a card slot 5 that cooperates with the stopper 4, and the stopper 4 is inserted into the card slot 5 to press the turntable frame 2 tightly against the fixed pile 1.

[0034] One end of the slide groove 3 near the direction in which the turntable frame 2 enters and exits is provided with a curved arc part 3a, and the curved arc part 3a of the slide groove 3 is bent away from the card slot 5; the stopper 4 enters the curved arc part 3a, and the slider is disengaged from the card slot 5.

[0035] The turntable frame 2 and the fixed pile 1 are not improved in this application and are the same as those in CN 219728395 U, so they will not be elaborated here. In the normal working state, the turntable frame 2 is driven by an AGV cart to enter the fixed pile 1 and is fixed by the locking system on the fixed pile 1 after being in place.

[0036] Before the turnover rack 2 enters the fixed pile 1 in this application, the driving cylinder 6 drives the stopper 4 to the end of the arc part of the chute 3, as Figure 1 shown. At this time, the stopper 4 retracts inward and will not affect the normal entry and exit of the turnover rack 2 into and out of the fixed pile 1. After the turnover rack 2 enters the fixed pile 1, the driving cylinder 6 pushes the stopper 4 to move in the reverse direction. The movement of the stopper 4 in the arc part can be decomposed into front-back movement and left-right movement. On the one hand, the stopper 4 moves in the left-right direction towards the card slot 5, and finally inserts the stopper 4 into the card slot 5. At the same time, the stopper 4 moves back and forth and gradually approaches the end of the card slot 5. Then the driving cylinder 6 pushes the stopper 4 to continue moving forward. Finally, the stopper 4 presses against the end of the card slot 5, applies a forward force to the turnover rack 2, and presses the turnover rack 2 against the fixed pile 1. Specifically, the fixed pile 1 is provided with a blocking structure, and the turnover rack 2 abuts against the blocking structure of the fixed pile 1.

[0037] As Figure 1 shown, the fixed pile 1 includes two left and right legs, and a gap for the AGV cart to pass through is reserved between the two legs; locking systems are respectively arranged on the two left and right legs of the fixed pile 1.

[0038] Since the stopper 4 will enter the arc part of the card slot 5 for movement, the legs are provided with rotating shafts, and the driving cylinder 6 is rotatably installed on the rotating shafts. When the stopper 4 enters the arc part, the driving cylinder 6 can offset its own axis by rotating.

[0039] As Figure 3 shown, the stopper 4 includes a sliding part 4a, a connecting part 4b and a blocking part 4c. The sliding part 4a is embedded in the chute 3 and slides along the chute 3. The two ends of the connecting part 4b are respectively connected to the sliding part 4a and the blocking part 4c, and the connecting part 4b is connected to the driving rod of the driving cylinder 6. The blocking part 4c extends towards the chute 3 and is inserted into the chute 3, and abuts against the end of the chute 3 to press against the turnover rack 2.

[0040] Specifically, the sliding part 4a extends along the direction of the chute 3. In this way, the sliding part 4a is stuck in the chute 3, which can prevent the blocking part 4c of the entire stopper 4 from rotating after being stressed. The torque generated by the blocking part 4c of the stopper 4 will be transmitted to the sliding part 4a, and the front and rear ends of the sliding part 4a will respectively abut against the left and right sides of the chute 3, thereby generating opposite counter torques to keep the entire blocking part 4c balanced.

[0041] At the same time, since the sliding part 4a needs to enter the arc part of the chute 3. Therefore, the cross-section of the sliding part 4a is smaller than the cross-section of the chute 3; a gap is reserved between the sliding part 4a and the inner wall of the chute 3. In this way, when the sliding part 4a slides in the arc part of the chute 3, the reserved gap can compensate for the bending of the arc part. Ensure that the sliding part 4a can also slide freely in the arc part.

[0042] The driving cylinder 6 is arranged parallel to the direction in which the turnover rack 2 enters and exits the fixed pile 1.

[0043] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0044] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without conflict. To avoid unnecessary repetition, the present invention does not separately describe various possible combination methods.

[0045] Furthermore, any combination can be made among various different embodiments of the present invention, as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
