This design can adjust the spreader to meet the production needs of different models, greatly improving the flexibility and efficiency of the production line. However, the spreader is currently adjusted manually according to the model, which is time-consuming and labor-intensive.

[0032] In order to realize automatic adjustment of a sling and meet the needs of current production rhythm, the utility model proposes a sling adjustment mechanism.

[0033] See also Figures 1 to 3 In one embodiment of the utility model, the sling adjustment mechanism 100 is used for a sling of a vehicle production conveyor line, the sling includes a support arm, a support arm that is telescopically adjustable relative to the support arm, and a locking mechanism for fixing the support arm and the support arm, the sling adjustment mechanism 100 includes a base 110, a first positioning member 200 and a second positioning member 300 disposed on the base 110, and an unlocking mechanism 400 disposed on the base 110; the first positioning member 200 is used to position the support arm, and the first positioning member 200 can move up and down relative to the base 110; the second positioning member 300 is used to position the support arm, and the second positioning member 300 can move from one end of the base 110 to the other end relative to the base 110, and approach or move away from the first positioning member 200; and the second positioning member 300 can move up and down relative to the base 110; the support arm and the support arm are fixed by the first positioning member 200 and the second positioning member 300 respectively, and the length of the support arm and the support arm is adjusted by the forward and backward movement of the second positioning member 300 relative to the first positioning member 200.

[0034] According to the technical solution of the utility model, after the sling moves to the sling adjustment mechanism 100, the locking mechanism that locks the support arm and the support arm is first unlocked, so that the support arm can move relative to the support arm; in one embodiment, the unlocking process can be manual unlocking, and in another embodiment, the locking mechanism is unlocked by an unlocking mechanism 400 arranged on the base 110, and the specific structure of the locking mechanism is introduced later; secondly, the support arm is positioned by the first positioning member 200, and the support arm is positioned by the second positioning member 300; furthermore, the support arm is driven to a length suitable for the corresponding vehicle model by the movement of the second positioning member 300, so as to adjust the length of the support arm, and the sling is adjusted by the sling adjustment mechanism 100, thereby reducing labor input and improving production efficiency.

[0035] Specifically, the vehicle production conveyor line is equipped with a conveying hanger, which is driven by a motor to move the hanger along the predetermined production route of the track, so as to complete various assembly operations of the car body mounted on the hanger; the hanger adjustment mechanism 100 is arranged below the hanger, for example, it can be fixed at the entrance of the hanger conveying track; as the main load-bearing structure of the hanger, the support arm is fixed on the base 110, and the support arm is designed to be retractable, corresponding to the support arm, and can be adjusted through telescopic adjustment to adapt to the length change of vehicle production. The support arm directly contacts and supports the vehicle production to ensure stability during the lifting process.

[0036] The sling includes two booms, each boom includes a supporting arm and a supporting arm, and the two booms can be opened and closed through driving control, and the opening and closing directions are left and right; and the supporting arm moves in the front-back direction, and changes in the up-down direction relative to the ground.

[0037] When the length of the sling needs to be adjusted, the sling is moved to the top of the sling adjustment mechanism 100, and the first positioning member 200 is connected to the pin shaft hole on the support arm through a positioning pin to realize the positioning of the support arm.

[0038] After the first positioning member 200 is positioned with the support arm, a positioning pin is provided on the second positioning member 300. After the second positioning member 300 moves left and right relative to the base 110 to the position of the pin shaft hole corresponding to the support arm, it moves up and down relative to the base 110 so that the positioning pin cooperates with the pin shaft hole. The first positioning member 200 respectively realizes the positioning of the support arm and the support arm to ensure the accuracy of positioning. Because the support arm and the support arm are locked by a locking mechanism, an unlocking mechanism 400 corresponding to the locking mechanism is also provided on the base 110. The unlocking process of the locking mechanism by the unlocking mechanism 400 can be after the first positioning member 200 and the second positioning member 300 are respectively positioned with the boom; or the locking mechanism can be unlocked before the first positioning member 200 positions the support arm. The locking mechanism can be a spring buckle, a latch, or a rotating pin lock. The unlocking mechanism 400 is a mechanical structure corresponding to the locking principle of the locking mechanism.

[0039] Most hoists use a rotating pin lock to fix the support arm and the support arm. The rotating pin lock is locked or unlocked by rotation. Specifically, the unlocking mechanism 400 includes an unlocking member 410 and a two-way drive assembly 420 that is transmission-connected to the unlocking member 410. The two-way drive assembly 420 includes a release drive member 430 and a lifting drive member 440 that is transmission-connected to the release drive member 430. The unlocking member 410 is transmission-connected to the lifting drive member 440, and the release drive member 430 drives the lifting drive member 440 to move left and right.

[0040] After moving up and down, the unlocking member 410 can abut against the lever of the rotating pin lock, and unlocking is achieved by moving the lever left and right. In one embodiment, the unlocking member 410 is driven by hydraulics to achieve vertical up and down movement and horizontal left and right movement of the unlocking member 410 on the base 110; in another embodiment, two or four high-precision linear servo motors are used, which are directly connected to the unlocking member 410 or connected through a transmission mechanism (such as a ball screw).

[0041] Reference Figure 2 and Figure 3 In this embodiment, the bidirectional driving assembly 420 includes a release driving member 430 and a lifting driving member 440 that is transmission-connected to the release driving member 430, the unlocking member 410 is transmission-connected to the lifting driving member 440, the release driving member 430 drives the lifting driving member 440 to move left and right, specifically, the lifting driving member 440 is configured as a lifting cylinder, the release driving member 430 is configured as a release cylinder, the bidirectional driving assembly 420 also includes a connecting frame 450, the connecting frame 450 is slidingly connected to the base 110, the driving shaft of the release cylinder is connected to the connecting frame 450, the lifting cylinder is installed on the connecting frame 450, and the unlocking member 410 is connected to the driving shaft of the lifting cylinder.

[0042] In other embodiments, the lifting drive member 440 and the release drive member 430 may also be configured as a motor or a cylinder.

[0043] In this embodiment, the sling adjustment mechanism 100 also includes a mounting bracket 500 and a second driving member 600. The mounting bracket 500 can be movably connected to the base 110 and moved closer to or away from the first positioning member 200. The second driving member 600 is installed on the mounting bracket 500, and the second positioning member 300 is transmission-connected to the second driving member 600. Specifically, the second driving member 600 is configured as a second driving cylinder, which is installed on the upper side of the mounting bracket 500. Both ends of the second positioning member 300 are slidingly connected to the mounting bracket 500. The driving shaft of the second driving cylinder is provided with a clamping portion, and the middle part of the second positioning member 300 is provided with a fixing portion, and the clamping portion is connected to the fixing portion.

[0044] The side close to the base 110 is usually defined as the "lower side", and the side opposite thereto is defined as the "upper side". The mounting bracket 500 is an independent connecting component, and is connected to the base 110 by sliding, ensuring the stability and smoothness of the sliding process. Compared with the sliding connection of the second driving member 600 to the base 110, the structure is simplified, and the sliding accuracy and stability are improved. As an independent component, the mounting bracket 500 can be repaired or replaced more easily if a problem occurs, without the need to make large-scale changes to the entire sling adjustment mechanism 100. Moreover, through the mounting bracket 500, the modular design of the sling adjustment mechanism 100 can be realized, making the connection between different components clearer and simpler, and convenient for assembly and disassembly. The second driving member 600 is configured as a second cylinder, and the response speed is usually faster, which can meet the demand for rapid positioning of the sling adjustment mechanism 100. The cost of the cylinder may be relatively low, which is more in line with the requirements of cost-effectiveness. The second driving member 600 is arranged on the upper side of the mounting bracket 500, which is more in line with the structural layout and transmission requirements, so that the smoothness and stability of the transmission process can be ensured.

[0045] Furthermore, the sling adjustment mechanism 100 also includes a moving mechanism 700, which is disposed on the base 110, and the mounting bracket 500 is slidably connected to the base 110, and the moving mechanism 700 is used to drive the mounting bracket 500. The base 110 is a frame structure, which reduces the weight cost of the base 110, and a fixing frame 120 is disposed on one end of the base 110, and both ends of the first positioning member 200 are connected to the fixing frame 120 through a slide rail. The first positioning member 200 is driven by a cylinder like the second positioning member 300, and the first driving member 210 is a first driving cylinder arranged on the upper side of the fixing frame 120, and is connected to the first positioning member 200 through the driving shaft of the first driving cylinder.

[0046] In one embodiment, the first positioning member 200 is arranged on the outer side of the fixing frame 120 (the side away from the mounting bracket 500); in another embodiment, the first positioning member 200 is arranged on the inner side of the fixing frame 120 (the side close to the mounting bracket 500). In order to improve the structural stability of the fixing frame 120, the fixing frame 120 and the base 110 are connected by inclined pipe members 130 at both ends of the side of the fixing frame 120 away from the first positioning member, and an inclined support is formed between the base 110 and the fixing frame 120 to improve the force-bearing capacity of the fixing frame 120.

[0047] In one embodiment, the second positioning member 300 is arranged on the outer side of the mounting bracket 500 (the side away from the fixing frame 120); in another embodiment, the second positioning member 300 is arranged on the inner side of the mounting bracket 500 (the side close to the fixing frame), and the relative positions of the first positioning member 200 and the second positioning member 300 can be arranged on the fixing frame 120 and the mounting bracket 500 as needed; for example, when the first positioning member 200 is arranged on the outer side of the fixing frame 120, the second positioning member 300 is arranged on the inner side of the mounting bracket 500; or, when the first positioning member 200 is arranged on the outer side of the fixing frame, the second positioning member 300 is arranged on the inner side of the mounting bracket 500.

[0048] The mounting bracket 500 is also a frame structure to reduce weight and cost. The two ends of the lower side of the mounting bracket 500 are connected to the base 110 through slide rails. The two ends of the second positioning member 300 are connected to the mounting bracket 500 through slide rails. The second driving cylinder is arranged on the upper side of the mounting bracket 500. The driving shaft of the second driving cylinder is provided with a double fork arm with a hole. The second positioning member 300 has a protrusion with a hole, which is inserted into the double fork arm and fixed by a pin shaft.

[0049] In order to save cost and weight, the base 110 , the mounting bracket 500 and the fixing frame 120 are all composed of square tubes. The base 110 is also provided with an adjustable foot 140 which can adjust the height of the base 110 from the ground.

[0050] The two ends of the mounting bracket 500 are slidably connected to the base 110, and the sliding connection between the mounting bracket 500 and the base 110 is realized by a guide rail and a slider. The base 110 is provided with a guide rail, and the two ends of the mounting bracket 500 cooperate with the guide rail through the slider to realize the sliding connection. This connection method is simple and reliable, and can ensure that the mounting bracket 500 slides steadily and smoothly on the base 110.

[0051] The moving mechanism 700 includes a first servo motor 710 and a transmission assembly 720. The transmission assembly 720 includes a screw rod 721 that is connected to the motor shaft of the first servo motor 710 and a guide block that cooperates with the screw rod 721. The screw rod 721 is arranged in the middle of the lower side of the mounting bracket 500, and the guide block is connected to the mounting bracket 500. As a precision control mechanism, the servo motor can provide high-precision position, speed and acceleration control. The servo motor has a large torque output capacity and can cope with various load conditions that may occur in the sling adjustment mechanism 100. The screw rod 721 transmission has the characteristics of high structural stability and smooth movement. This stability can ensure that the mounting bracket 500 will not produce excessive vibration or shaking during the movement, thereby further improving the accuracy and safety of the work. Arranging the servo motor and the screw rod 721 transmission in the middle of the lower side of the mounting bracket 500 is conducive to reducing the volume and weight of the entire sling adjustment mechanism 100, and is also conducive to improving the compactness and stability of the structure. The screw rod 721 is arranged at the middle of the lower side of the mounting bracket 500, which can ensure that the screw rod 721 and the guide block are more closely matched and stable, thereby improving the efficiency and accuracy of the transmission. In addition, this layout is also conducive to reducing friction and loss during the transmission process, further improving the working efficiency and reliability of the entire system.

[0054] There are two pin adjustment members 820 and two pin drive members 810, each corresponding to a boom; the two pin adjustment members 820 and the pin drive members 810 are arranged on the second positioning member 300. After the second positioning member 300 is positioned with the support arm, the pin drive member 810 drives the second servo motor to move to the adjustment sleeve 821 to cooperate with the pin assembly, and the second servo motor drives the adjustment sleeve 821 to rotate, thereby adjusting the relative distance between the two pin assemblies and adjusting the width direction distance of the two booms.

[0055] In order to realize the automatic control process, the spreader adjustment device further includes a detector for detecting the spreader and a controller electrically connected to the detector, and the controller controls the start-up of the spreader adjustment mechanism 100 .
