[0049] like Figure 1-2 As shown, a sled conveying system of an embodiment of the utility model comprises a roller bed 1, a sled 2, a positioning assembly 3 and two auxiliary positioning components 4. The roller bed 1 is connected to the platform, the sled 2 is arranged above the roller bed 1, and the positioning assembly 3 is connected to the sled 2 for positioning the vehicle body 10; the two auxiliary positioning components 4 are symmetrically distributed on both sides of the roller bed 1 and located outside the roller bed 1, and the bottom of the auxiliary positioning components 4 is fixed to the platform, and the auxiliary positioning components 4 can push the vehicle body 10 to perform lifting and lowering movements. Generally, after the vehicle body 10 is sprayed with paint in the paint shop, the vehicle body 10 recognition system recognizes the vehicle model, and then the transplanter transports it to the corresponding sled conveying device of the corresponding model. Since the body 10 may have a processing error of about 5mm during the processing and assembly process, or the body 10 is not aligned with the positioning assembly 3 after the transplanter transfers the body 10, which may cause the body 10 to tilt and other problems, the body 10 needs to be lifted up, and then the relative positions of the sled 2, the positioning assembly 3 and the body 10 need to be adjusted, so that the body 10 and the positioning assembly 3 are aligned and connected with the sled 2, and finally the body 10 is transferred to the final assembly warehouse. The present application replaces manual intervention to lift the body 10 with mechanical assistance without making any changes to the existing body 10 transportation method, improves ergonomics and eliminates safety hazards, is easy to operate, flexible to use, and has high work efficiency.

[0050] like Figure 1-7In a preferred embodiment shown in the figure, each of the two auxiliary positioning parts 4 includes a plurality of auxiliary positioning components 41, and each auxiliary positioning component 41 includes a base 411, a lifting mechanism 412 and a support plate 413. The base 411 is fixed to the platform, the bottom of the lifting mechanism 412 is fixed to the side of the base 411 close to the roller bed 1, and the bottom of the support plate 413 is connected to the top of the lifting mechanism 412, and is used to support the vehicle body 10, wherein the vehicle body 10 is driven away from or close to the sled 2 by the lifting mechanism 412 and the support plate 413. In the present application, the number of auxiliary positioning components 41 can be 2 to 8, preferably 2 or 4. For the convenience of description, it is taken as an example that two auxiliary positioning components 41 are respectively arranged on both sides of the roller bed 1 in the attached figure, as shown in the attached figure. Figure 1-5 As shown, the four auxiliary positioning components 41 can be started simultaneously when the positioning of the vehicle body 10 fails; then, the lifting mechanism 412 drives the support plate 413 to move upward and contact the vehicle body 10, and then continues to push the vehicle body 10 upward, so that the vehicle body 10 is separated from the sled 2 and the positioning component 3. After repositioning and alignment, the lifting mechanism 412 drives the support plate 413 and the vehicle body 10 thereon to move downward, so that the vehicle body 10 is aligned with the positioning component 3 and falls on the top of the sled 2. Finally, the lifting structure 412 continues to drive the support plate 413 to move downward to restore to its initial position. This implementation can use four auxiliary positioning components 41 to replace manual lifting of the vehicle, improve ergonomics, eliminate safety hazards, and improve work efficiency.

[0051] like Figure 1-7 In a preferred embodiment shown, the lifting mechanism 412 includes a cylinder 4121 and a first channel steel 4122, the cylinder 4121 includes a cylinder body and a cylinder rod, the cylinder body is fixed to the base 411, the first channel steel 4122 is fixed to the side of the cylinder rod away from the roller bed 1, and the bottom of the support plate 413 is fixed to the top of the first channel steel 4122; wherein, the cylinder 4121 drives the first channel steel 4122 and the support plate 413 to perform lifting and lowering movements. In addition, the lifting mechanism 412 also includes a gas source for providing gas to the cylinder 4121, and a solenoid valve is connected between the gas source and the cylinder 4121. When the vehicle body 10 does not match the positioning assembly 3, the solenoid valve is opened and the four cylinders 4121 are started at the same time, so that the vehicle body 10 is lifted up smoothly. This is equivalent to adding a vehicle body 10 lifting station on both sides of the roller bed 1, using four cylinders 4121 as the driving force output source, which is simple to work, has good stability, and high work efficiency. The first channel steel 4122 has high strength and long life, and can support the lifting of the vehicle body 10 for more than 10 times. The support plate 413 is provided with a limit groove corresponding to the vehicle body 10, and the frame at the bottom of the vehicle body 10 can be inserted into the limit groove, which can prevent the vehicle body 10 from shaking during the lifting process, making the connection between the support plate 413 and the vehicle body 10 more stable.

[0052] like Figure 1-7In a preferred embodiment shown, the auxiliary positioning assembly 41 also includes a guide mechanism 414 for guiding the lifting mechanism 412, and the guide mechanism 414 includes a second channel steel 4141, a linear guide rail 4142 and a slider 4143. The second channel steel 4141 is fixed to the side of the base 411 away from the roller bed 1, the linear guide rail 4142 is fixed to the second channel steel 4141, the slider 4143 is slidably connected to the linear guide rail 4142, and the first channel steel 4122 is fixed to the slider 4143, wherein the first channel steel 4122 performs linear motion through the cooperation of the linear guide rail 4142 and the slider 4143. In this way, the four auxiliary positioning assemblies 41 respectively use the linear guide rail 4142 and the slider 4143 to ensure that the first channel steel 4122 and the vehicle body 10 perform linear lifting motion. The present application realizes an intelligent auxiliary device by using the cylinder 4121 and the linear slide rail in combination, improves work efficiency, and eliminates safety hazards such as ergonomics.

[0053] like Figure 1-7 In a preferred embodiment shown, the extension directions of the first channel steel 4122, the second channel steel 4141, and the linear guide rail 4142 are respectively perpendicular to the extension direction of the roller bed 1. In this way, the planes where the first channel steel 4122 and the second channel steel 4141 are located move relative to each other, and the linear guide rail 4142 and the slider 4143 cooperate to ensure that the cylinder 4121 outputs a vertical torque, so that the vehicle body 10 is smoothly lifted or lowered, thereby improving the safety of the equipment.

[0054] like Figure 1-7 In a preferred embodiment shown, the two auxiliary positioning components 4 also include a detection assembly for detecting the height between the support plate 413 and the platform. This ensures that the vehicle body 10 is lifted to a specified height, so that the vehicle body 10 is completely separated from the skid 2, and facilitates the subsequent alignment of the vehicle body 10 and the positioning assembly 3.

[0055] like Figure 1-7 In a preferred embodiment shown, a nylon pad is provided on the upper surface of the support plate 413. The friction between the support plate 413 and the vehicle body 10 can be increased, and the support plate 413 is prevented from scratching the vehicle body 10.

[0056] like Figure 1-7 In a preferred embodiment shown, there are multiple positioning components 3, and the multiple positioning components 3 are used to align and limit the bottom plate of the vehicle body 10. Each positioning component 3 includes a bracket 31 and a positioning pin 32, and the positioning pin 32 is fixed to the bracket 31. After the positioning pin 32 and the vehicle body 10 are aligned, the vehicle body 10 is fixed on the sled 2, so that the vehicle body 10 can be transferred to the next process. There can be 2 to 10 positioning components 3, which can be set according to different vehicle models, such as Figure 4-5As shown, the slide 2 in this embodiment is provided with five positioning components 3, and the five positioning components 3 can be matched with the five groups of positioning holes on the bottom plate of the vehicle body 10. It should be noted that since the vehicle body 10 has been inspected and matched before the transfer, the position of the positioning component 3 in this application is fixed, and even if the processing error is generally within 5mm, the positioning component 5 and the vehicle body 10 can be matched by moving the slide 2 forward and backward.

[0057] like Figure 1-7 In a preferred embodiment shown, the sled conveying system further includes a support assembly 5 for supporting a plurality of sleds 2, the support assembly 5 including a plurality of support block groups 51, and the support block groups 51 are connected to the bracket 31. Because of limited space, a plurality of sleds 2 need to be stacked to improve space utilization, and the support assembly 5 can support the sleds 2 thereon to keep them stable.

[0058] like Figure 1-7 In a preferred embodiment shown in FIG. 1 , the sled conveying system further includes a guide block group 6 for guiding the plurality of sleds 2 when stacking. The guide block group 6 includes two guide blocks 61. The two guide blocks 61 are symmetrically arranged and connected to both sides of one of the brackets 31. Figure 1-5 As shown, the guide block 61 is "L"-shaped, and the guide block 61 matches the shape of the slide 2, so that when the slide 2 is stacked, it can be stacked smoothly under the guidance of the guide block 61, avoiding the slide 2 from tilting and falling when stacking.

[0059] The specific principles are as follows:

[0060] When the vehicle body 10 and the positioning component 3 do not match and tilt, first, operate the roller bed to the manual state, and then use the special key to open the permissions of the vehicle body 10 and the auxiliary positioning component 4; then determine the skewed position of the vehicle body 10, control the solenoid valve ventilation through the button, and ventilate the four cylinders 4121 at the same time, and lift the vehicle body 10 and separate it from the sled 2 by converting the telescopic movement of the cylinder 4121 into a lifting movement; then, by operating the roller bed 1 to move the position of the sled 2, re-match the vehicle body 10 hole and the positioning pin 2; finally, return the matched vehicle body 10 and the auxiliary positioning component 4 to their original positions, and the vehicle body 10 is transferred to the final assembly warehouse. This application realizes an intelligent auxiliary device by using a cylinder and a linear slide rail in combination; a non-standard support and towing design with good stability and high work efficiency; the advantage of using mechanical force instead of manpower; and solves ergonomics and eliminates safety hazards.
