Description

Technical Field

[0002] During vehicle processing, some jigs are often needed to assist in processing. For example, in order to improve the anti-rust performance of the vehicle, a layer of anti-rust wax needs to be sprayed between the plate seams of the vehicle body. Before spraying the anti-rust wax, a jig is needed to support the vehicle body hood. This process is generally completed manually. Workers need to walk to the jig placement rack to get the jig, and then return to the front of the vehicle body to install the jig on the vehicle body hood. As the vehicle body moves on the production line, the anti-rust wax is sprayed. At this time, the worker needs to remove the jig from the vehicle body and walk back to the jig placement rack with the jig in hand to place the jig. This process requires workers to be careful to avoid the jig hitting the vehicle body and other equipment, so there is a waste of walking and movement, which leads to an increase in actual working hours and affects the production mobility.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] During the vehicle processing, some jigs are needed for auxiliary processing. For example, in order to ensure the quality of the vehicle and improve the anti-rust performance of the vehicle, a layer of anti-rust wax needs to be sprayed between the plate seams of the vehicle body. During this process, the operator needs to first take the jig from the jig placement rack and install the jig under the cross beam of the water tank in the engine compartment of the vehicle body, and use the jig to prop up the vehicle body hood. Then the vehicle moves forward with the production line, and the vehicle gradually moves away from the jig placement rack. During this process, the anti-rust wax is sprayed between the vehicle plate seams. After the anti-rust wax is sprayed, the operator needs to move to the side of the vehicle body, remove the jig from the vehicle body, and then walk back to the vicinity of the jig placement rack with the jig in hand. If the next vehicle to be processed has arrived near the jig placement rack at this time, the jig will be installed on the next vehicle to be processed. If the next vehicle to be processed has not arrived at this time, the jig will be placed on the jig placement rack, and the jig will be taken from the jig placement rack and installed on the vehicle body after the next vehicle to be processed arrives.

[0039] The applicant observed and found that after the body panel seams were sprayed, the operator took the jig from the body and walked back to the vicinity of the jig placement rack with the jig in hand. Since it was necessary to pay attention to avoid the jig hitting the body or other equipment, this process required careful operation, which led to waste of walking and movement. The average working time for each car in this process was 11 seconds. Based on 2 shifts per day and 280 cars needing to be processed per shift, the monthly working time is: 11 seconds / car × 280 cars / shift × 2 shifts / day × 22 days / month = 37.6 hours / In the month, if the vehicle body is hit during the process of taking the fixture, the vehicle needs to be repaired. The average repair time for each vehicle is 900 seconds. The applicant has found through statistics that an average of 2 vehicles need to be repaired in each shift, so the monthly repair time is: 900 seconds / vehicle × 2 vehicles / shift × 2 shifts / day × 22 days / month = 22 hours / month. It can be seen that the above process is time-consuming, resulting in a longer actual working time for the body panel seam spraying process, while the planned working time for the body panel seam spraying process remains unchanged, thus affecting the production availability of the vehicle in this process.

[0040] In view of this, the present invention proposes an automatic conveying device 100 to solve the above problems.

[0041] In one embodiment of the present invention, please refer to Figure 1 to Figure 2The automatic conveying device 100 includes a bracket 1, a first slide rail 2, a second slide rail 3, a first fixed pulley 4, a conveying assembly 5, a counterweight assembly 6 and a traction member 7, wherein the bracket 1 includes a first vertical frame 11 and a second vertical frame 12 that are arranged opposite to each other; the first slide rail 2 is arranged obliquely, the higher end of the first slide rail 2 is installed on the first vertical frame 11, and the lower end of the first slide rail 2 is installed on the second vertical frame 12; the second slide rail 3 is arranged below the first slide rail 2, and the two ends of the second slide rail 3 are respectively installed on the first vertical frame 11 and the second vertical frame 12, and the second slide rail 3 is arranged obliquely, and the inclination direction of the second slide rail 3 is the same as that of the first slide rail 2. The inclination direction of a slide rail 2 is the same; the first fixed pulley 4 is installed at the higher end of the first slide rail 2, and / or, the first fixed pulley 4 is installed at one end of the second slide rail 3 close to the first vertical frame 11, and / or, the first fixed pulley 4 is installed on the first vertical frame 11; the conveying component 5 is slidably installed on the first slide rail 2, and the counterweight component 6 is slidably installed on the second slide rail 3, and / or, the conveying component 5 is slidably installed on the second slide rail 3, and the counterweight component 6 is slidably installed on the first slide rail 2; one end of the traction member 7 is connected to the conveying component 5, and the other end bypasses the first fixed pulley 4 and is connected to the counterweight component 6.

[0042] Specifically, the planes where the first frame 11 and the second frame 12 are located are parallel to each other, and the planes where the first frame 11 and the second frame 12 are located are both perpendicular to the ground or the bottom plate. On this basis, the two ends of the first slide rail 2 are respectively connected to the first frame 11 and the second frame 12. The higher end of the first slide rail 2 is installed on the first frame 11, and the lower end is installed on the second frame 12, so that the first slide rail 2 is kept inclined. The second slide rail 3 has the same inclination direction as the first slide rail 2, and its two ends are respectively connected to the first frame 11 and the second frame 12. In order to achieve the transmission function, the first fixed pulley 4 needs to be installed on the first frame 11, or installed on the end of the first slide rail 2 or the second slide rail 3 close to the first frame 11. In this embodiment, the number of the first fixed pulley 4 is one, and it is installed at the higher end of the first slide rail 2; in other embodiments, the number of the first fixed pulley 4 can be set to multiple, and multiple first fixed pulleys 4 can be installed on any one of the first frame 11, the first slide rail 2 and the second slide rail 3, or installed on these structures at the same time as needed. In order to realize the automatic transportation function of the jig, it is also necessary to set up a transportation component 5, a counterweight component 6 and a traction member 7. The transportation component 5 is used to load and transport the jig, and the counterweight component 6 is used to provide power for the movement of the transportation component 5. There are two types of positional relationships between the transportation component 5 and the counterweight component 6. The first type is that the transportation component 5 is installed on the first slide rail 2, and the counterweight component 6 is installed on the second slide rail 3; the second type is that the transportation component 5 is installed on the second slide rail 3, and the counterweight component 6 is installed on the first slide rail 2. Both the transportation component 5 and the counterweight component 6 can be slidably arranged on the first slide rail 2 or the second slide rail 3. In order to prevent the jig with a long length from colliding with the floor during transportation, the first positional relationship is selected in this embodiment. On this basis, the traction member 7 is used as a transmission member between the transportation component 5 and the counterweight component 6. One end of the traction member 7 is connected to the transportation component 5, and the other end bypasses the first fixed pulley 4 and is connected to the counterweight component 6.

[0043] In this embodiment, when the transport assembly 5 is not loaded with a jig, the counterweight assembly 6 slides toward the second frame 12, and drives the transport assembly 5 to slide toward the first frame 11 through the traction member 7 and the first fixed pulley 4 until the transport assembly 5 reaches the highest point it can reach. When the transport assembly 5 is loaded with a jig, due to the action of gravity, the transport assembly 5 loaded with the jig slides toward the second frame 12, and at the same time drives the counterweight assembly 6 to slide toward the first frame 11 through the traction member 7 and the first fixed pulley 4 until the transport assembly 5 reaches the lowest point it can reach, at which time the automatic transport of the jig is completed. When the jig is removed from the transport assembly 5, the transport assembly 5 returns to the highest point it can reach, that is, the initial position, under the action of the counterweight assembly 6, the traction member 7 and the first fixed pulley 4. Among them, when the transport assembly 5 loaded with the jig is stationary and parked at one end of the second frame 12, it can be used as a jig placement rack.

[0044] Through the technical solution provided by the utility model, during the process of spraying the body panel seam, the operator only needs to stand near the second stand 12, then take the jig from the conveying assembly 5, and install the jig on the vehicle to be processed. At this time, since the jig is taken, the conveying assembly 5 moves to the end of the first slide rail 2 close to the first stand 11 under the action of the counterweight assembly 6, the traction member 7 and the first fixed pulley 4. When the vehicle moves to the vicinity of the first stand 11 along the production line, the body panel seam is sprayed, and the operator also moves to the vicinity of the first stand 11, removes the jig from the vehicle body, and then loads it on the conveying assembly 5. At this time, since the sum of the weight of the jig and the conveying assembly 5 along the first slide rail 2 is greater than the sum of the weight of the counterweight assembly 6 along the second slide rail 3 and the friction force, the conveying assembly 5 can drive the jig to slide to the end of the first slide rail 2 close to the second stand 12. When the transport assembly 5 drives the jig to stop at one end of the second stand 12, it can replace the jig placement rack to place the jig, and the operator only needs to walk to the vicinity of the second stand 12 to perform the next cycle of operations. Since the operator does not need to hold the jig when walking back to the vicinity of the first stand 11, there is no waste of movement and walking, and there is no risk of the jig colliding with the vehicle body, so it can avoid affecting the production mobility.

[0045] The applicant has found through statistics that the use of automatic transport devices 100 instead of manual operations can reduce the walking time of operators from 11 seconds / unit to 6 seconds / unit. The working hours for this process per month are: 6 seconds / unit × 280 units / shift × 2 shifts / day × 22 days / month = 20.5 hours / month. At the same time, there is no need to repair the vehicle, so the monthly vehicle repair time is 0 hours / month. The total working hours saved are: 37.6 hours / month + 22 hours / month - 20.5 hours / month = 39.1 hours / month, which greatly reduces the time spent on the process of removing the jig from the body and placing it on the jig placement rack, thereby avoiding affecting the production availability of the body panel seam spraying process.

[0046] Further, the transport assembly 5 includes a transport pulley block 51 and a transport member 52 installed on the transport pulley block 51, and the transport pulley block 51 is used to drive the transport member 52 to move on the first slide rail 2 or the second slide rail 3; the counterweight assembly 6 includes a counterweight pulley block 61 and a counterweight member 62 installed on the counterweight pulley block 61, and the counterweight pulley block 61 is used to drive the counterweight member 62 to move on the first slide rail 2 or the second slide rail 3. For details, please refer to Figure 1 , Figure 4 and Figure 6The transport assembly 5 includes a transport pulley block 51 and a transport member 52. The transport pulley block 51 includes four pulleys that can slide on the first slide rail 2. The four pulleys are jointly clamped on the first slide rail 2. On one side of the four pulleys, a transport member 52 is installed. The transport member 52 can keep synchronous movement with the transport pulley block 51. At the same time, a hook that can load the jig is provided on the transport member 52. For some small jigs, the part for loading the jig can also be a strong magnet to prevent the jig from falling during transportation. The counterweight assembly 6 cooperates with the transport assembly 5 to complete the transportation of the jig and the recovery of the transport assembly 5. The counterweight assembly 6 includes a counterweight pulley block 61 and a counterweight member 62. Please refer to Figure 6 The counterweight pulley block 61 includes four pulleys that can slide on the second slide rail 3. The pulleys used in the counterweight pulley block 61 and the transport pulley block 51 have the same specifications to reduce the design difficulty. When the pulleys of the same specifications cannot meet the design requirements, the counterweight pulley block 61 and the transport pulley block 51 can use pulleys of different specifications; the counterweight pulley block 61 is clamped on the second slide rail 3, and the counterweight member 62 is installed on one side of the counterweight pulley block 61 so that it can move synchronously with the counterweight pulley block 61. The counterweight member 62 has a certain weight, and its weight design should meet the following requirements: when the jig is loaded on the transport assembly 5, the counterweight assembly 6 can be pulled and slid along the second slide rail 3 toward the first stand 11 under the action of the transport assembly 5, the traction member 7 and the first fixed pulley 4; when the jig is unloaded from the transport assembly 5, the counterweight assembly 6 can pull the transport assembly 5 to slide along the first slide rail 2 toward the first stand 11 through the traction member 7 and the first fixed pulley 4.

[0047] By setting a pulley group in the conveying component 5 and the counterweight component 6, the friction force on the conveying component 5 and the counterweight component 6 can be greatly reduced, which is conducive to the sliding of the conveying component 5 and the counterweight component 6 on the first slide rail 2 and the second slide rail 3, thereby reducing the design difficulty and avoiding the situation where the conveying component 5 still cannot slide after the jig is loaded.

[0048] In addition, the automatic transport device 100 further includes a limiter 8, which is mounted on the first stand 11, and / or the limiter 8 is mounted on the second stand 12, and the limiter 8 is used to prevent the transport component 5 or the counterweight component 6 from hitting the bracket 1. There are many ways to implement the limiter 8. In one embodiment of the utility model, the limiter 8 is one, which is mounted on the first stand 11 or the second stand 12, and is located between the first slide rail 2 and the second slide rail 3. One end of the limiter 8 is connected to the first stand 11 or the second stand 12, and the other end is a straight tube. The upper and lower ends of the straight tube correspond to the positions of the transport component 5 and the counterweight component 6, respectively, so as to prevent the transport component 5 and the counterweight component 6 from hitting the bracket 1.

[0049] In another embodiment of the present invention, the number of the limiting members 8 is two, see Figure 1, two stoppers 8 are respectively installed on the first stand 11 and the second stand 12, and are installed at the connection between the second slide rail 3 and the first stand 11 and the second stand 12. When the counterweight assembly 6 slides to the vicinity of the first stand 11, it will be blocked by the stopper 8 on the first stand 11 to stop sliding. Due to the length limitation of the traction member 7 between the counterweight assembly 6 and the conveying assembly 5, when the counterweight assembly 6 stops sliding, it will also drive the conveying assembly 5 to stop sliding, thereby preventing the conveying assembly 5 from colliding with the second stand 12. Similarly, when the counterweight assembly 6 slides to the vicinity of the second stand 12 and contacts the stopper 8, due to the blocking of the stopper 8, the counterweight assembly 6 will stop sliding and drive the conveying assembly 5 to stop sliding. When there are two stoppers 8, there are multiple combinations of their installation positions. The two stoppers 8 can be installed at the connection between the first slide rail 2 and the bracket 1 on both sides, or can be installed at the connection between the first stand 11 and the first slide rail 2 and the second slide rail 3, or can be installed at the connection between the second stand 12 and the first slide rail 2 and the second slide rail 3. During design, the length of the traction member 7 needs to be such that after one of the transport component 5 and the counterweight component 6 stops after contacting the stopper 8, the other can also stop before colliding with the bracket 1. By adopting the above arrangement, on the one hand, the purpose of preventing the transport component 5 and the counterweight component 6 from colliding with the bracket 1 can be achieved, so that when the jig is transported, a certain distance can be maintained between the jig and the bracket 1 to avoid the jig and the bracket 1 from colliding and damaging the jig; on the other hand, it can prevent the bracket 1 from directly colliding with the transport component 5 and the counterweight component 6, thereby increasing the service life of the bracket 1.

[0050] In one embodiment of the present invention, the automatic transport device 100 further includes a second fixed pulley 9, which is disposed on a stopper 8 mounted on the first stand 11, one end of the traction member 7 is connected to the transport assembly 5, and the other end bypasses the first fixed pulley 4 and the second fixed pulley 9 and is connected to the counterweight assembly 6. Figure 1 and Figure 5 On the basis of providing two limit members 8 and one of the two limit members 8 being mounted on the first stand 11, the second fixed pulley 9 is mounted on the limit member 8 located on the first stand 11. In this embodiment, one of the two limit members 8 is mounted at the connection between the second slide rail 3 and the first stand 11, and the second fixed pulley 9 is mounted on the limit member 8. Figure 2 and Figure 7The first fixed pulley 4 is installed at the higher end of the first slide rail 2, and the first fixed pulley 4 is correspondingly arranged with the second fixed pulley 9, which is used to adjust the transmission trajectory of the traction member 7, so that the traction member 7 located on the second slide rail 3 can be arranged parallel to the second slide rail 3, so that it can maintain parallelism with the axis of the counterweight assembly 6 along the direction of the second slide rail 3, thereby reducing the loss of the gravity component of the counterweight assembly 6, which is beneficial to the transmission of force between the counterweight assembly 6 and the conveying assembly 5, can reduce the design difficulty, and at the same time is beneficial to reduce the design weight of the counterweight member 62 in the counterweight assembly 6 and reduce the manufacturing cost.

[0051] In one embodiment of the present invention, a shock absorbing portion 81 is provided at one end of the stopper 8 facing the conveying assembly 5 or the counterweight assembly 6. Specifically, if the stopper 8 is used to prevent the conveying assembly 5 from colliding with the bracket 1, the shock absorbing portion 81 is provided at one end of the stopper 8 facing the conveying assembly 5; if the stopper 8 is used to prevent the counterweight assembly 6 from colliding with the bracket 1, the shock absorbing portion 81 is provided at one end of the stopper 8 facing the counterweight assembly 6. Figure 1 and Figure 5 In this embodiment, the stopper 8 is used to prevent the counterweight assembly 6 from colliding with the bracket 1, so a shock absorbing part 81 is provided at the end facing the counterweight assembly 6, and the cross-sectional dimension of the shock absorbing part 81 is larger than the cross-sectional dimension of the rest of the stopper 8, so as to increase the contact area with the counterweight assembly 6, reduce the local pressure, and prevent the counterweight assembly 6 from being damaged during the collision with the shock absorbing part 81. In addition, a soft cushion is provided at the end of the shock absorbing part 81 facing the counterweight assembly 6, and this arrangement can further reduce the risk of damage caused by the stopper 8 when colliding with the counterweight assembly 6. On the other hand, this arrangement can reduce the noise generated when the counterweight assembly 6 collides with the stopper 8, and eliminate or at least reduce the risk of occupational health and safety.

[0052] In one embodiment of the present invention, please refer to Figures 1 to 3 The first slide rail 2 and the second slide rail 3 are arranged in parallel. This arrangement can reduce a set of design variables in the design stage, that is, the influence of the angle between the first slide rail and the second slide rail on the design is not considered, thereby reducing the design difficulty. If the first slide rail 2 and the second slide rail 3 are not arranged in parallel, there are multiple possible angles between the two, and each angle corresponds to a different weight design of the counterweight 62, which increases the design difficulty. In this embodiment, the angle between the first slide rail and the second stand is preferably 110° to 120°.

[0053] In one embodiment of the utility model, the first slide rail 2 and the second slide rail 3 are arranged in a horizontal direction, and the horizontal distance between the first slide rail 2 and the second slide rail 3 is used for the conveying assembly 5 and the counterweight assembly 6 loaded with the conveyed objects to pass through. Specifically, there are two types of positional relationships between the first slide rail 2 and the second slide rail 3 in the horizontal direction. The first type is as follows: Figure 3As shown, the first slide rail 2 is installed at the edge of the bracket 1, and the second slide rail 3 is installed on the side of the first slide rail 2 close to the center line of the bracket 1, and is arranged at a distance from the first slide rail 2; the second position relationship is opposite to the first position relationship, the second slide rail 3 is installed at the edge of the bracket 1, the first slide rail 2 is installed on the side of the second slide rail 3 close to the center line of the bracket 1, and is arranged at a distance from the second slide rail 3. In this embodiment, the transport component 5 is installed on the first slide rail 2, and the counterweight component 6 is installed on the second slide rail 3. When the first position relationship is adopted, please refer to Figure 3 At this time, there is a horizontal spacing L between the first slide rail 2 and the second slide rail 3 in the horizontal direction. In this case, the size of the horizontal spacing L needs to be large enough for the counterweight assembly 6 to pass through, so as to avoid collision between the counterweight assembly 6 and the first slide rail 2 due to its excessive size; when the second position relationship is adopted, a horizontal spacing L still needs to be set between the first slide rail 2 and the second slide rail 3 in the horizontal direction. In this case, the size of the horizontal spacing L needs to be larger than the sum of the sizes of the transport assembly 5 and the transported items, so as to allow the transport assembly 5 loaded with the transported items to pass through, so as to avoid collision between the transported items and the second slide rail 3 and damage to the transported items.

[0054] In one embodiment of the utility model, the traction member 7 includes a fishing line 7a, one end of which is connected to the transport assembly 5, and the other end of which is connected to the counterweight assembly 6 by passing the first fixed pulley 4. The fishing line 7a has the advantages of smooth surface, small deadweight, high toughness, wear resistance, low unit price and easy acquisition. By using the fishing line 7a as the traction member 7, the friction between the traction member 7 and the first fixed pulley 4 and the second fixed pulley 9 can be reduced, and the gravity effect of the fishing line 7a on the transmission between the transport assembly 5 and the counterweight assembly 6 can be ignored. On the one hand, the transmission process between the transport assembly 5 and the counterweight assembly 6 can be made smoother. On the other hand, the calculation of two parameters such as the friction on the surface of the traction member 7 and the deadweight of the traction member 7 can be ignored during design, thereby reducing the difficulty of design.
