Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot manufacturing equipment technology, and in particular to a palletizing fixture. Background Technology

[0002] Aluminum ingot stacking refers to the neat arrangement of finished aluminum ingots according to certain rules for storage, transportation, and subsequent processing. A reasonable stacking method can improve space utilization, ensure ingot quality, and increase operational efficiency. However, existing dedicated stacking clamps are prone to scattering during ingot handling due to errors inherent in the ingot casting process. This can lead to improper stacking and even serious safety accidents.

[0003] To address the aforementioned issues, patent document CN204999322U discloses a novel high-efficiency aluminum ingot stacker robotic gripper. This gripper includes a fixed base, a connecting plate, a support plate, a cylinder, grippers, and anti-slip blocks. The connecting plate is located on top of the fixed base, with a support plate on its upper part. The connecting base is located in the middle of the support plate. A cylinder is fixedly mounted in the middle of the fixed base, and a bracket is located at the head of the cylinder. A gripper is rotatably connected to one side of the bracket via a rotating shaft, and a hanging plate is connected to one side of the gripper via a rotating shaft. The anti-slip blocks are fixedly connected to the inner wall of the grippers with screws. The anti-slip blocks are elastically deformable. When in use, the elastic anti-slip blocks adapt to fluctuations in the size of the aluminum ingots through material deformation (such as compression and expansion), avoiding the instability or slippage problems caused by errors in traditional rigid grippers, thus preventing the ingots from scattering.

[0004] However, the above-mentioned clamps still have the following problems when in use: 1. The elastic anti-slip block mainly clamps the aluminum ingots through friction. When there is oil, oxide layer or unevenness on the surface of the aluminum ingot, the elasticity of the anti-slip block is difficult to provide enough friction, which makes the aluminum ingot slip or fall during handling or stacking; 2. At present, the robot stacks according to the preset height during the stacking process. This fixed mode is prone to throwing or hitting the upper layer of aluminum ingot when the aluminum ingot is too thin or too thick, which affects the normal stacking process. Utility Model Content

[0005] This utility model provides a palletizing clamp to solve the technical problem in the prior art where the elastic anti-slip block relies on friction to clamp aluminum ingots, which is easily affected by surface oil, oxide layer or unevenness, causing the aluminum ingots to slip off.

[0006] To solve the above problems, the palletizing fixture provided by this utility model adopts the following technical solution:

[0007] A palletizing fixture includes a fixture body and an elastic mechanism, wherein the fixture body includes a support plate and clamping assemblies mounted on two opposite sides of the support plate;

[0008] The elastic mechanism includes an elastic component and a clamping plate. The clamping plate is installed on the side of the clamping component facing the aluminum ingot, and the elastic component is installed on the clamping component and perpendicular to the clamping plate.

[0009] The clamping plate includes a vertical section and a horizontal section connected to the bottom of the vertical section, the horizontal section extending toward the aluminum ingot;

[0010] The elastic component has a clamping element at the end facing the aluminum ingot for pressing against the aluminum ingot.

[0011] The beneficial effects of the palletizing fixture provided by this utility model are as follows: by installing an elastic mechanism including an elastic component and a clamping plate on the clamping assembly, the elasticity of the elastic mechanism automatically adapts to the size of the aluminum ingot, maintaining the clamping force of the clamping assembly on the aluminum ingot. By setting the clamping plate to a structure including a vertical section and a horizontal section, the horizontal section supports the aluminum ingot, providing stable support for the aluminum ingot and ensuring that the aluminum ingot does not slip during the transfer process due to factors such as surface oil, oxide layer, and unevenness. This fully utilizes the synergistic effect between the elastic component and the clamping plate.

[0012] Through the above-mentioned design, this utility model effectively solves the technical problem in the prior art where the elastic anti-slip block relies on friction to clamp the aluminum ingot, which is easily affected by surface oil, oxide layer or unevenness, causing the aluminum ingot to slip off.

[0013] Furthermore, a thickness measuring structure is installed on the support plate, which includes a distance sensor and an auxiliary detection component for measuring the height of the aluminum ingot.

[0014] Furthermore, the auxiliary detection component includes at least two guide sleeves installed on the support plate and spaced apart. Each guide sleeve contains a guide post that passes through the support plate and extends downward. The bottom end of the guide post is connected to a detection pressure plate.

[0015] Furthermore, the upper end of the guide post is connected to a horizontally extending limiting plate located above the ranging sensor.

[0016] Furthermore, the elastic component includes a first sleeve, a second sleeve, a pin, and a spring. The first sleeve and the second sleeve are both mounted on the clamping component, and the second sleeve is placed inside the first sleeve. The pin passes through the first sleeve and the second sleeve. The spring is fitted onto the pin and is located inside the second sleeve. The two ends of the spring are respectively connected to the end of the second sleeve away from the aluminum ingot and the abutment.

[0017] Furthermore, a drive mechanism is installed on the support plate to drive the clamping assembly to open or close.

[0018] Furthermore, the output end of the drive mechanism is connected to the clamping assembly via a self-lubricating copper sleeve.

[0019] Furthermore, the clamping assembly includes a push arm and a clamping arm, which are connected by a pivot.

[0020] Furthermore, a connecting flange is installed on the support plate for connecting a palletizing robot.

[0021] Furthermore, the ranging sensor is a laser ranging sensor. Attached Figure Description

[0030] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0031] Embodiments of the palletizing fixture provided by this utility model:

[0032] like Figures 1 to 5 As shown, the palletizing fixture includes a fixture body, an elastic mechanism, a thickness measuring structure, and a driving mechanism. The fixture body includes a support plate 1 and clamping assemblies mounted on two opposite sides of the support plate 1. An elastic mechanism is mounted on each clamping assembly. The thickness measuring structure and the driving mechanism are both mounted on the support plate 1, and the driving mechanism is connected to the clamping assemblies.

[0033] Regarding the clamping assembly, drive mechanism, and the connection between the clamping assembly and drive mechanism. For example... Figure 4 As shown, the clamping assembly includes a push arm 17 and a clamping arm 18, which are connected by a rotating shaft 19. In this embodiment, the driving mechanism is a cylinder 15, which is connected to the push arm 17 via a self-lubricating copper sleeve 16. The cylinder 15 drives the push arm 17 to open and close, thereby driving the clamping arm 18 to open and close.

[0034] Regarding flexible mechanisms. For example... Figure 4 and Figure 5 As shown, the elastic mechanism includes an elastic component and a clamping plate 22. The clamping plate 22 is installed on the side of the clamping component facing the aluminum ingot 2. The elastic component is installed on the clamping component and is perpendicular to the clamping plate 22. In this embodiment, both the clamping plate 22 and the elastic component are installed on the side of the clamping arm 18 facing the aluminum ingot 2. The clamping plate 22 includes a vertical section 3 and a horizontal section 4 connected to the bottom of the vertical section 3. The horizontal section 4 extends toward the aluminum ingot 2.

[0035] In this embodiment, the elastic component includes a first sleeve 11, a second sleeve 12, a pin 13, and a spring 14. Both the first sleeve 11 and the second sleeve 12 are mounted on the clamping arm 18, with the second sleeve 12 positioned inside the first sleeve 11. The pin 13 passes through both the first sleeve 11 and the second sleeve 12. The spring 14 is fitted onto the pin 13 and located inside the second sleeve 12. Both ends of the spring 14 are connected to the end of the second sleeve 12 facing away from the aluminum ingot 2 and the abutment 5, respectively. In this embodiment, the first end of the pin 13 facing away from the spring 14 has a threaded section, on which a limit nut 21 is screwed. In other embodiments, the elastic component is made of rubber.

[0036] In this embodiment, two adjacent elastic components in the horizontal direction are connected by a rectangular connecting plate 23. In other embodiments, each elastic component is equipped with a connecting plate 23, which is circular or square.

[0037] Regarding thickness measurement structures. For example... Figures 2 to 4As shown, the thickness measuring structure is mounted on the support plate 1 and includes a distance sensor and an auxiliary detection assembly for measuring the height of the aluminum ingot 2. The auxiliary detection assembly includes at least two guide sleeves 7 mounted on the support plate 1 and spaced apart. Each guide sleeve 7 contains a guide post 8 that passes through the support plate 1 and extends downwards. The support plate 1 has through holes for the guide posts 8 to pass through. The bottom ends of the guide posts 8 are on the same horizontal plane and connected by a detection pressure plate 9. The upper end of the guide post 8 is connected to a horizontally extending limiting plate 10 located above the distance sensor.

[0038] In this embodiment, the ranging sensor is a laser ranging sensor 6, and there are two guide sleeves 7. The upper end of the left guide post 8 is connected to a limiting plate 10. In other embodiments, the ranging sensor is an ultrasonic ranging sensor, an infrared ranging sensor, or a visual ranging sensor, and there are three or more guide sleeves 7. The upper end of the guide post 8 near the ranging sensor is connected to a limiting plate 10.

[0039] In addition, a connecting flange 20 is installed at the center of the top surface of the support plate 1 for connection with the palletizing robot, and the laser range sensor 6 is connected to the controller signal of the palletizing robot.

[0040] The working principle of the palletizing fixture provided by this utility model is as follows: First, the output end of the cylinder 15 extends, driving the push arm 17 to unfold outward, thereby unfolding the clamping arm 18 outward so that the two clamping arms 18 are respectively located at both ends of the length direction of the aluminum ingot 2; then, the output end of the cylinder 15 retracts, causing the clamping arm 18 to clamp the aluminum ingot 2. At this time, the horizontal section 4 provides support for the end of the aluminum ingot 2, the clamping member 5 contacts the side of the end of the aluminum ingot 2, the spring 14 is compressed under the action of the aluminum ingot 2, and at the same time, the detection pressure plate 9 moves down to contact the highest point of the top surface of the aluminum ingot 2. The laser distance sensor 6 measures the distance between itself and the detection pressure plate 9 and transmits the detected height information to the controller of the palletizing robot, which controls the palletizing robot to adjust the height of the next palletizing; then the aluminum ingot 2 is transported to the designated position; finally, the output end of the cylinder 15 extends, causing the clamping arm 18 and the push arm 17 to open, thereby allowing the aluminum ingot 2 to be lowered; repeating the above steps completes the palletizing work of the aluminum ingot 2.
