Description

Technical Field

[0001] This invention relates to the field of palletizing technology, and more specifically to a palletizing fixture for automotive parts logistics. Background Technology

[0002] There are two scenarios when palletizing automotive parts. First, production transfer is required simultaneously with palletizing; second, parts need to be palletized into foam boxes upon leaving the factory. The placement methods differ between these two palletizing approaches. When placed in a foam box, the parts are horizontally positioned, perfectly fitting the locking mechanism within the box. However, during production transfer, the parts are placed at an angle. This method prevents parts from squeezing against each other and makes subsequent retrieval easier.

[0003] However, the requirements for the fixture differ between tilted and horizontal placement. For horizontal placement, the fixture needs stronger gripping force and must hold the parts from all sides. For tilted placement, the fixture must not grip the bottom of the parts to avoid contact between the bottom gripping area and the placement frame.

[0004] When workers transport the finished parts to the palletizing station, existing technology requires two palletizing stations and two palletizing machines. Whether considering the floor space, equipment maintenance costs, or the cost of the mobile equipment connected to the fixture, this approach is inferior to a single palletizing machine with full-featured palletizing capabilities.

[0005] Therefore, it is necessary to design a palletizing fixture for automotive parts that can be used for both horizontal and inclined palletizing of automotive parts. A fixture with both palletizing capabilities will not significantly increase manufacturing costs, nor will it increase maintenance difficulty due to the added functionality. Summary of the Invention

[0006] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a palletizing fixture for automotive parts logistics, applicable to both horizontal and inclined palletizing of automotive parts.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a palletizing fixture for automotive parts, including a connecting frame, a switching rotation mechanism, a rotating frame, a second pressure clamp, a blocking mechanism, a tilting rotation mechanism, a rotating arm, and three first pressure clamps. The rotating frame is rotatably mounted on the bottom of the connecting frame. The three first pressure clamps and the second pressure clamp are used to clamp the four sides of the parts. The three first pressure clamps are fixedly connected to the rotating frame. The rotating arm is rotatably mounted on the rotating frame. The second pressure clamp is fixedly mounted on the rotating arm. The tilting rotation mechanism and the switching rotation mechanism are both fixedly mounted on the connecting frame. The tilting rotation mechanism is used to control the rotation and swing of the rotating arm. The switching rotation mechanism is used to control the rotation and swing of the rotating frame. The blocking mechanism is fixedly mounted on the rotating frame. The blocking mechanism is provided with a blocking plate that can move horizontally and be inserted into the bottom of the parts.

[0008] Preferably, the second pressure clamp includes two clamping arms, a pressure plate, a guide post, a connecting block, a spring, and two sliding posts. The two clamping arms are horizontally slidably mounted on the rotating arm. The pressure plate is located between the two clamping arms. The guide post is vertically slidably mounted on the rotating arm. The pressure plate is fixedly mounted on the bottom of the guide post. The connecting block is fixedly mounted on the top of the guide post. The two sliding posts are fixedly mounted on the connecting block. The clamping arms have sliding holes for the sliding posts to slide. The spring is sleeved on the guide post and provides a downward elastic force to the pressure plate.

[0009] Preferably, the tilting and rotating mechanism is a pull rod, one end of which is hinged to the connecting frame, and the other end of which is hinged to the rotating arm.

[0010] Preferably, a slide rail is fixedly provided at the bottom of the rotating arm, and a slide block is fixedly provided on the clamping arm, with the slide block slidably connected to the slide rail.

[0011] Preferably, the inner side of the clamping arm is provided with an anti-slip pad that contacts the component, and the structure of the first pressure clamp is the same as that of the second pressure clamp.

[0012] Preferably, the switching rotation mechanism includes an electric push rod, a bent plate, a slider, and a sliding column. One end of the bent plate is fixedly connected to the rotating frame, and the bent part of the bent plate is rotatably connected to the connecting frame. The other end of the bent plate is provided with a sliding hole. The electric push rod is fixedly installed on the connecting frame, and the sliding column is fixedly installed on the output end of the electric push rod through the slider. The sliding column is inserted into the sliding hole.

[0013] Preferably, the blocking mechanism includes an electric push rod II, a hinge rod, and a connecting seat. The connecting seat is horizontally slidably mounted on the rotating frame. The blocking plate is fixedly mounted on the bottom of the connecting seat. The electric push rod II is mounted on the rotating frame, and the output end of the electric push rod II is hinged to the hinge rod.

[0014] Preferably, each baffle plate, connecting seat and hinge rod constitute a set of support arms. Multiple sets of support arms are provided on the rotating frame. The baffle plate on each set of support arms is used to insert into the bottom of the component. One end of the hinge rod on each support arm is hinged to the output end of the electric push rod two.

[0015] Preferably, a guide post 2 is fixedly installed on the rotating frame to allow the connecting seat to slide horizontally.

[0016] Preferably, the connecting frame, the tilting and rotating mechanism, and the pull rod are initially positioned in a triangular shape.

[0017] The beneficial effects of this invention are that the automotive parts logistics palletizing fixture can be applied to both horizontal and inclined palletizing of automotive parts. The fixture, equipped with both palletizing functions, is controlled by a pull rod, which neither significantly increases the manufacturing cost of the fixture nor makes its maintenance more difficult due to the addition of this function.

[0018] Furthermore, when pressed down, the first and second pressure clamps can automatically clamp and lock the parts; when the switching rotation mechanism drives the rotating frame to rotate, the second pressure clamp can automatically unlock; when the first and second pressure clamps are pulled upward, they can also automatically unlock with the parts, thus having an automatic unlocking function.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: This invention provides a palletizing fixture for automotive parts logistics, including a connecting frame 1, a switching rotation mechanism 2, a rotating frame 3, a second pressure clamp 5, a blocking mechanism 6, a tilting rotation mechanism 7, a rotating arm 8, and three first pressure clamps 4. The rotating frame 3 is rotatably mounted on the bottom of the connecting frame 1, and the top of the connecting frame 1 is connected to a mobile device. The three first pressure clamps 4 and the second pressure clamp 5 are used to clamp the four sides of the parts 10. The three first pressure clamps 4 are fixedly connected to the rotating frame 3. The rotating arm 8 is rotatably mounted on the rotating frame 3, and the second pressure clamp 5 is fixedly mounted on the rotating arm 8. The tilting rotation mechanism 7 and the switching rotation mechanism 2 are both fixedly mounted on the connecting frame 1. The tilting rotation mechanism 7 is used to control the rotation and swing of the rotating arm 8, and the switching rotation mechanism 2 is used to control the rotation and swing of the rotating frame 3. The blocking mechanism 6 is fixedly mounted on the rotating frame 3, and the blocking mechanism 6 is provided with a blocking plate 6a that can move horizontally and be inserted into the bottom of the parts 10. By pushing the connecting frame 1 downwards via the mobile device connected to the top of the connecting frame 1, the three pressing clamps 4 and 5 move towards the component 10. Once the pressing clamps 4 and 5 contact the component 10, they clamp the component 10 as they continue to move downwards. Subsequently, the blocking mechanism 6 drives the blocking plate 6a to insert into the bottom of the component 10, thus completing the clamping and fixing of the component 10, resulting in the following configuration: Figure 1 The state shown.

[0033] This fixing method eliminates the need for electrical connection between the first and second clamping devices 4 and 5, reducing wiring clutter and eliminating the need for automatic clamping control. It automatically releases when separation is required, enabling automatic unlocking and locking. Furthermore, after clamping, the bottom of component 10 is supported by the blocking plate 6a, preventing component 10 from separating. The clamped component 10 can then be moved by a mobile device and placed horizontally into a foam box.

[0034] When it is necessary to tilt and stack component 10, the rotating mechanism 2 drives the rotating frame 3 to rotate automatically. During rotation, the tilting rotating mechanism 7 pulls the rotating arm 8 to rotate automatically. Simultaneously, the pressure gripper 5 automatically unlocks from component 10, and in this state, component 10 is placed into the placement rack 9. The final result will be as follows: Figure 2 and Figure 3 The state shown above ensures that when component 10 is placed at an angle, the bottom gripping part will not come into contact with the placement frame, thus meeting the usage requirements for the angled placement state.

[0035] To ensure that the pressure gripper 2 5 can automatically separate from the component 10 during the rotation of the rotating arm 8, the pressure gripper 2 5 includes two gripping arms 5a, a pressure plate 5b, a guide post 5c, a connecting block 5d, a spring 5f, and two sliding posts 5e. The two gripping arms 5a are horizontally slidable on the rotating arm 8, the pressure plate 5b is located between the two gripping arms 5a, and the guide post 5c is vertically slidable on the rotating arm 8. The pressure plate 5b is fixed. The guide post 5c is mounted at the bottom, the connecting block 5d is fixedly mounted at the top of the guide post 5c, and the two sliding posts 5e are fixedly mounted on the connecting block 5d. The clamping arm 5a has a sliding hole 5a1 for the sliding posts 5e to slide. The spring 5f is sleeved on the guide post 5c and provides a downward elastic force to the lower pressure plate 5b, causing the two clamping arms 5a to initially tend to open. One end of the spring 5f abuts against the lower pressure plate 5b, and the other end abuts against the rotating arm 8. When the lower pressure plate 5b is pressed down until it contacts the top of the component 10, as the rotating arm 8 continues to move downward, the lower pressure plate 5b remains stationary. The sliding posts 5e push the two clamping arms 5a towards the center, clamping the component 10 and thus achieving automatic locking of the component 10.

[0036] When the rotating arm 8 is from Figure 1 Rotate to the state shown Figure 2 In the indicated state, the specific movement is as follows: The switching rotation mechanism 2 drives the rotating frame 3 to rotate, and the component 10 rotates together with the rotating frame 3. The component 10 pushes the clamping arm 5a near the inner side. The distance the clamping arm 5a moves inward is x, and the downward distance is less than x. This ensures that the downward-moving transmission plate can never contact the component 10, ultimately achieving the unlocking effect. During this process, the rotating arm 8 rotates relative to the rotating frame 3. That is, during the rotation of the rotating arm 8, the downward clamping device 2 5 can automatically separate from the component 10.

[0037] The transmission ratio can be changed by controlling the slope of the sliding hole 5a1. It is only necessary to ensure that when component 10 pushes the clamping arm 5a, the lower pressure plate 5b descends without colliding with itself. In actual use, simulations have verified that this requirement can be achieved.

[0038] The tilting and rotating mechanism 7 is a tie rod, with one end hinged to the connecting frame 1 and the other end hinged to the rotating arm 8. When the rotating arm 8 is in a horizontal state, the tilting and rotating mechanism 7 can limit and horizontally support the rotating arm 8. When the rotating frame 3 rotates, the tilting and rotating mechanism 7 pulls the middle position of the rotating arm 8, causing the rotating arm 8 to rotate relative to the rotating frame 3, thus driving the rotating arm 8 to rotate.

[0039] By using a tilting rotation mechanism 7 to drive the rotating arm 8 to rotate, the manufacturing cost of the fixture will not be significantly increased, nor will the maintenance difficulty of the fixture be increased due to the addition of this function, even when both palletizing functions are available.

[0040] A slide rail 5h is fixedly installed at the bottom of the rotating arm 8, and a slide block 5j is fixedly installed on the clamping arm 5a. The slide block 5j is slidably connected to the slide rail 5h. The horizontal sliding function of the clamping arm 5a is realized through the function of the slide rail 5h and the slide block 5j.

[0041] The inner side of the clamping arm 5a is provided with an anti-slip pad 5k that contacts the part 10. The structure of the first pressure clamp 4 is the same as that of the second pressure clamp 5. Utilizing the function of the anti-slip pad 5k, the anti-slip pad 5k provides anti-slip and shock absorption after clamping the part 10. The only difference between the first pressure clamp 4 and the second pressure clamp 5 is in their dimensions; the clamping dimensions need to be designed according to the final clamping position.

[0042] The switching rotation mechanism 2 includes an electric push rod 2a, a bent plate 2b, a slider 2c, and a sliding column 2d. One end of the bent plate 2b is fixedly connected to the rotating frame 3, and the bent part of the bent plate 2b is rotatably connected to the connecting frame 1. The other end of the bent plate 2b has a sliding hole 2b1. The electric push rod 2a is fixedly installed on the connecting frame 1, and the sliding column 2d is fixedly installed on the output end of the electric push rod 2a through the slider 2c. The sliding column 2d is inserted into the sliding hole 2b1. By pulling the slider 2c upward with the electric push rod 2a, the sliding column 2d slides along the inside of the sliding hole 2b1, and at the same time, the bent plate 2b is rotated. With this rotation method, when the equipment is not working, the weight is mainly concentrated on the connecting frame 1, and it will not put too much burden on the output end of the electric push rod 2a.

[0043] The blocking mechanism 6 includes an electric push rod 6b, a hinge rod 6c, and a connecting seat 6d. The connecting seat 6d is horizontally slidably mounted on the rotating frame 3. The blocking plate 6a is fixedly mounted on the bottom of the connecting seat 6d. The electric push rod 6b is mounted on the rotating frame 3, and its output end is hinged to the hinge rod 6c. By controlling the electric push rod 6b to work, it can pull the blocking plate 6a horizontally via the hinge rod 6c, allowing the blocking plate 6a to be inserted into and removed from the bottom of the component 10.

[0044] Each baffle plate 6a, connecting seat 6d, and hinge rod 6c constitutes a set of support arms. Multiple sets of support arms are provided on the rotating frame 3. The baffle plate 6a on each support arm is used to insert into the bottom of the component 10, and one end of the hinge rod 6c on each support arm is hinged to the output end of the electric push rod 6b. By setting multiple support arms, multiple support points can be provided for the component 10. These support points not only support the component 10 more effectively but also enable synchronous control.

[0045] A guide post 6e is fixedly mounted on the rotating frame 3 to allow the connecting seat 6d to slide horizontally. With the support of the guide post 6e, the connecting seat 6d can slide horizontally. Furthermore, after the blocking plate 6a supports the component 10, its entire weight will be transferred to the rotating frame 3, which can improve the stability of the support.

[0046] The connecting frame 1, the tilting and rotating mechanism 7, and the pull rod are initially positioned in a triangular shape. This triangular structure provides greater stability, preventing the rotating arm 8 from being pushed and rotated when the pressure clamp 5 presses down to clamp the component 10.

[0047] In use, the mobile device connected to the top of the connecting frame 1 pushes the connecting frame 1 downwards, causing the three pressing clamps 4 and 5 to move towards the component 10. After the pressing clamps 4 and 5 come into contact with the component 10, they continue to move downwards, clamping the component 10. Subsequently, the blocking mechanism 6 drives the blocking plate 6a to insert into the bottom of the component 10, thus completing the clamping and fixing of the component 10, presenting as shown in the figure. Figure 1 The state shown.

[0048] When it is necessary to tilt and stack component 10, the rotating mechanism 2 drives the rotating frame 3 to rotate automatically. During rotation, the tilting rotating mechanism 7 pulls the rotating arm 8 to rotate automatically. At the same time, the pressure gripper 5 will automatically unlock due to contact with component 10 during rotation. Component 10 is then placed into the placement rack 9 in this state, and the final result will be as follows: Figure 2 and Figure 3 The state shown.

[0049] This automotive parts palletizing fixture is suitable for both horizontal and inclined palletizing of automotive parts. The fixture, equipped with both palletizing functions, is controlled by a lever, which neither significantly increases the manufacturing cost of the fixture nor makes its maintenance more difficult by adding this function.

[0050] Furthermore, when pressed down, the first pressing clamp 4 and the second pressing clamp 5 can automatically clamp and lock the component 10; when the switching rotation mechanism 2 drives the rotating frame 3 to rotate, the second pressing clamp 5 can automatically unlock; when the first pressing clamp 4 and the second pressing clamp 5 are pulled upward, they can also automatically unlock with the component 10, that is, they have an automatic unlocking function.

[0051] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
