Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and particularly relates to a body conveying system. Background Art

[0002] Currently, in the conveying design of the welding production line, the conveying system of the body-in-white assembly is usually combined with the fixture body. The lifting of the conveying system usually adopts the form of a large cylinder. The body-in-white is placed on the skid, and the skid usually walks by the motor driving the rollers to give the skid a frictional force for walking. Then, the skid drives the body-in-white to walk. When lifting or lowering the body, in order to ensure stability, the skid needs to be clamped by the precise positioning and clamping mechanism. After the body is lifted or lowered, the skid is released by the precise positioning and clamping mechanism. For one transportation of the body, the precise positioning and clamping mechanism needs to act four times (two clamps and two releases). Generally, each action of the precise positioning and clamping mechanism is used as a signal condition, and the next action can be carried out only after this signal condition is completed, resulting in a long conveying time. Moreover, for the existing conveying system, in order to prevent two skids from colliding, the previous skid needs to walk to a certain position before the next skid can walk, and 2 times of forward or backward operations need to be completed in one cycle, resulting in a long conveying time.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] By arranging the main jacking mechanism, the skid power mechanism and the auxiliary jacking mechanism in a straight line, a long span can be formed between these mechanisms, and then the skid mechanism is placed thereon, so that the skid mechanism can have a long span and can accommodate multiple vehicle bodies, thereby reducing the conveying time; when lifting or lowering the skid mechanism, the jacking power assembly on the main jacking mechanism can be used to drive the first support assembly to rise or fall. Due to the existence of the tie rod structure, when the first support assembly rises or falls, the second support assembly on the skid power mechanism and the third support assembly on the auxiliary jacking mechanism will be driven to rise or fall synchronously through the tie rod structure. Since the second support assembly is vertically slidably arranged on the vertical mounting assembly, the second support assembly can stably drive the skid mechanism to rise or fall. The third support assembly is used to assist the skid mechanism to rise or fall, which can reduce the distance between the first support assembly and the second support assembly, thereby reducing the span of the skid mechanism and making the vehicle body more stable during transportation. Therefore, it is possible to stably rise or fall without using a precise positioning and clamping mechanism to clamp or release the skid mechanism, so as to reduce the conveying time. The function of the traveling power assembly is to drive the skid mechanism to travel between the first support assembly, the second support assembly and the third support assembly;

[0017] The present invention can increase the accuracy of the rise or fall of the skid mechanism and greatly reduce the conveying time of the vehicle body. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. Specific embodiments

[0031] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] Please refer to Figures 1 to 10, shown is a body conveying system in the first embodiment of the present invention, including a skid mechanism 40, and a main lifting mechanism 10, a skid power mechanism 20, and an auxiliary lifting mechanism 30 arranged in a straight line. The main lifting mechanism 10 includes a lifting power assembly and a first support assembly connected to the lifting power assembly. The skid power mechanism 20 includes a vertical installation assembly, a second support assembly vertically slidably arranged on the vertical installation assembly, and a traveling power assembly arranged on the second support assembly. The auxiliary lifting mechanism 30 includes a third support assembly. The body conveying system further includes a tie rod structure 50 connecting the first support assembly, the second support assembly, and the third support assembly. The first support assembly, the second support assembly, and the third support assembly are all used to carry the skid mechanism 40, and the traveling power assembly is used to drive the skid mechanism 40 to travel.

[0035] It can be understood that in the present invention, by arranging the main lifting mechanism 10, the skid power mechanism 20, and the auxiliary lifting mechanism 30 in a straight line, a long span can be formed between these mechanisms, and then the skid mechanism 40 is placed thereon, so that the skid mechanism 40 can have a long span and can accommodate multiple bodies, thereby reducing the conveying time. When lifting or lowering the skid mechanism 40, the lifting power assembly on the main lifting mechanism 10 can be used to drive the first support assembly to rise or fall. Due to the existence of the tie rod structure 50, when the first support assembly rises or falls, it will drive the second support assembly on the skid power mechanism 20 and the third support assembly on the auxiliary lifting mechanism 30 to rise or fall synchronously through the tie rod structure 50. Since the second support assembly is vertically slidably arranged on the vertical installation assembly, the second support assembly can stably drive the skid mechanism 40 to rise or fall. The third support assembly is used to assist the skid mechanism 40 to rise or fall, which can reduce the distance between the first support assembly and the second support assembly, and thus reduce the span of the skid mechanism 40, making the body transportation process more stable. Therefore, it is not necessary to use a precise positioning and clamping mechanism to clamp or loosen the skid mechanism 40 to achieve stable rising or falling, so as to reduce the conveying time. The function of the traveling power assembly is to drive the skid mechanism 40 to travel between the first support assembly, the second support assembly, and the third support assembly.

[0036] The present invention can increase the accuracy of rising or falling of the skid mechanism 40 and greatly reduce the conveying time of the body.

[0037] Specifically, in this embodiment, the jacking power assembly includes a motor base 11, a jacking motor 111 disposed on the motor base 11, a jacking connecting shaft 112 disposed on the jacking motor 111, a rotating link 15 fixedly connected to the jacking connecting shaft 112, and a stretching link 16 rotatably connected to the rotating link 15. The first support assembly includes a first jacking link, which is in a hook shape and has a first bent rod 161 and a second bent rod 162, and a first connecting end 166 connecting the first bent rod 161 and the second bent rod 162. A first rotating shaft 17 is provided at the first connecting end 166, and the stretching link 16 is rotatably disposed on the first rotating shaft 17. The first support assembly further includes a first jacking base 12, a first jacking table 14 located above the first jacking base 12, and a first pulley set 141 disposed on the first jacking table 14. The first pulley set 141 is slidably connected to the skid mechanism 40. The first bent rod 161 is rotatably connected to the first jacking base 12 through a second rotating shaft 163, and the second bent rod 162 is rotatably connected to the first jacking table 14 through a third rotating shaft 164. Part of the tie rod structure 50 is rotatably connected to the first rotating shaft 17.

[0038] It can be understood that the jacking power assembly serves as the main power source for jacking up each jacking table. When it is necessary to raise the skid mechanism 40, the jacking motor 111 drives the jacking connecting shaft 112 and the rotating link 15 to rotate counterclockwise, and then the rotating link 15 pulls the stretching link 16 backward. Since the first bent rod 161 is rotatably connected to the first jacking base 12 through the second rotating shaft 163, the first jacking base 12 plays a limiting role on the first bent rod 161. Therefore, the stretching link 16 will pull the first jacking link through the first rotating shaft 17, driving the second bent rod 162 to rotate and move upward. Since the second bent rod 162 is rotatably connected to the first jacking table 14 through the third rotating shaft 164, the upward movement of the second bent rod 162 will drive the first jacking table 14 upward, thereby driving a part of the skid mechanism 40 to move upward. Moreover, the first connecting end 166 will also rotate and move upward under the action of the stretching link 16, driving part of the tie rod structure 50 upward. Similarly, when it is necessary to lower the skid mechanism 40, the jacking motor 111 is rotated in the reverse direction, and each structure can be reset, and finally the first jacking table 14 is lowered.

[0039] Further, the vertical mounting assembly includes a second jacking base 21 and a vertically arranged up-and-down sliding guide rail 227 provided on the second jacking base 21. The second support assembly includes a second jacking link. The second jacking link is in a hook shape and has a third bent rod 223 and a fourth bent rod 224, and a second connection end 222 connecting the third bent rod 223 and the fourth bent rod 224. A fourth rotating shaft 225 is provided at the second connection end 222. The second support assembly further includes a second jacking platform 24 located above the second jacking base 21 and a second pulley set 25 provided on the second jacking platform 24. The second jacking platform 24 is slidably arranged on the up-and-down sliding guide rail 227. The second pulley set 25 is slidably connected to the skid mechanism 40. The third bent rod 223 is rotatably connected to the second jacking base 21 through a fifth rotating shaft 226. A connecting block 26 is rotatably provided on the fourth bent rod 224. A front-and-back sliding guide rail 27 for the connecting block 26 to slide is provided on the second jacking platform 24. The traveling power assembly includes a traveling motor 23 fixedly connected to the second jacking platform 24, a traveling connecting shaft 231 connected to the traveling motor 23, and a traveling gear 232 provided on the traveling connecting shaft 231. Part of the tie rod structure 50 is rotatably connected to the fourth rotating shaft 225.

[0040] It can be understood that the vertical mounting assembly is the key structure to ensure the stable rising of each jacking platform. After part of the tie rod structure 50 at the jacking power assembly rises, it will cause part of the tie rod structure 50 at the skid power mechanism 20 to rise together, thereby driving the second connection end 222 to rotate and rise. The remaining movement principle of the second jacking link is the same as that of the first jacking link, which will not be elaborated here. When the fourth bent rod 224 rotates and rises, it will drive the connecting block 26 to rise together. The rising of the connecting block 26 will drive the second jacking platform 24 to rise. The function of the front-and-back sliding guide rail 27 is to enable the connecting block 26 to adaptively adjust its position on the front-and-back sliding guide rail 27 to prevent the structure from jamming. Due to the existence of the up-and-down sliding guide rail 227, when the second jacking platform 24 rises, it can ensure that the second jacking platform 24 is always horizontal. Since the traveling motor 23 is fixedly connected to the second jacking platform 24, the traveling motor 23 will rise with the second jacking platform 24. Since the skid mechanism 40 is provided on the second jacking platform 24, the traveling connecting shaft 231 and the traveling gear 232 on the traveling motor 23 will always be located below the skid mechanism 40.

[0041] Further, the third support assembly includes a third jacking link. The third jacking link is in a hook shape and has a fifth bent rod 322, a sixth bent rod 323, and a third connection end 324 connecting the fifth bent rod 322 and the sixth bent rod 323. A sixth rotating shaft 325 is provided at the third connection end 324. The third support assembly further includes a third jacking base 31, a third jacking platform 33 located above the third jacking base 31, and a third pulley group 34 provided on the third jacking platform 33. The third pulley group 34 is slidably connected to the skid mechanism 40. The fifth bent rod 322 is rotatably connected to the third jacking base 31 through a seventh rotating shaft 326, and the sixth bent rod 323 is rotatably connected to the third jacking platform 33 through an eighth rotating shaft 327. Part of the tie rod structure 50 is rotatably connected to the sixth rotating shaft 325.

[0042] It can be understood that the third support assembly is used to assist the skid mechanism 40 to rise. After part of the tie rod structure 50 at the jacking power assembly and the skid power mechanism 20 rises, part of the tie rod structure 50 at the auxiliary jacking mechanism 30 will also rise accordingly, thereby driving the third connection end 324 to rotate and rise. The movement principle of the rest of the third jacking link is the same as that of the first jacking link and the second jacking link, which will not be elaborated here.

[0043] Preferably, there are two auxiliary jacking mechanisms 30. One auxiliary jacking mechanism 30 is located between the main jacking mechanism 10 and the skid power mechanism 20, and the other auxiliary jacking mechanism 30 is located at one end of the skid power mechanism 20 away from the main jacking mechanism 10.

[0044] It can be understood that one auxiliary jacking mechanism 30 provided between the main jacking mechanism 10 and the skid power mechanism 20 can reduce the span of the skid mechanism 40 on the main jacking mechanism 10 and the skid power mechanism 20, making the mid-span of the skid mechanism 40 not easily deformed and more stable. The other auxiliary jacking mechanism 30 provided at one end of the skid power mechanism 20 away from the main jacking mechanism 10 is to extend the process of the entire conveying system, thereby lengthening the skid mechanism 40 so that the skid mechanism 40 can accommodate more vehicle bodies, thereby improving production efficiency.

[0045] Specifically, a plurality of positioning holes 51 are spaced apart in the tie rod structure 50. The plurality of positioning holes 51 are respectively rotatably connected to the first rotating shaft 17, the fourth rotating shaft 225, and the sixth rotating shaft 325.

[0046] Further, the skid mechanism 40 includes two reciprocating rods 41 arranged oppositely, a traveling rack 42 fixedly connected below the reciprocating rods 41, and a plurality of vehicle body positioning support blocks 43 spaced above the reciprocating rods 41. The traveling rack 42 meshes with the traveling gear 232, and the reciprocating rods 41 are slidably arranged on the first pulley set 141, the second pulley set 25, and the third pulley set 34.

[0047] It can be understood that the support blocks 43 on the reciprocating rods 41 serve as the main body for carrying the vehicle body. The traveling motor 23 rotates to drive the traveling gear 232 to rotate, thereby driving the traveling rack 42 to reciprocate. The traveling rack 42 then drives the reciprocating rods 41 to move, so as to transport the vehicle body. The functions of the first pulley set 141, the second pulley set 25, and the third pulley set 34 are to engage with the reciprocating rods 41. Since the second lifting platform 24 moves horizontally upward or downward, when the reciprocating rods 41 engage with the second pulley set 25 at the second lifting platform 24, it can ensure that the reciprocating rods 41 can always remain horizontal, enabling the first pulley set 141 and the third pulley set 34 to also always be in a horizontal state. Furthermore, it can make the first lifting platform 14 at the first pulley set 141 and the third lifting platform 33 at the third pulley set 34 also remain horizontal. This is the reason why only the up-and-down sliding guide 227 needs to be provided at the skid power mechanism 20, and no up-and-down sliding guide 227 needs to be provided at the main lifting mechanism 10 and the auxiliary lifting mechanism 30.

[0048] Preferably, the main lifting mechanism 10 further includes a first auxiliary lifting assembly. The first auxiliary lifting assembly includes a first cylinder connection base 13 and a first cylinder body 131 rotatably arranged on the first cylinder connection base 13. A ninth rotating shaft 165 is further provided at the first connection end 166. The extending end of the first cylinder body 131 is rotatably connected to the ninth rotating shaft 165. The skid power mechanism 20 further includes a second auxiliary lifting assembly. The second auxiliary lifting assembly includes a second cylinder connection base 22 and a second cylinder body 221 rotatably arranged on the second cylinder connection base 22. The extending end of the second cylinder body 221 is rotatably connected to the fourth rotating shaft 225. The auxiliary lifting mechanism 30 further includes a third auxiliary lifting assembly. The third auxiliary lifting assembly includes a third cylinder connection base 32 and a third cylinder body 321 rotatably arranged on the third cylinder connection base 32. The extending end of the third cylinder body 321 is rotatably connected to the sixth rotating shaft 325.

[0049] It can be understood that the first auxiliary lifting assembly, the second auxiliary lifting assembly, and the third auxiliary lifting assembly have the same principle and function. Here, the second auxiliary lifting assembly at the skid power mechanism 20 is taken as an example. Since the driving force for the second lifting link in the skid power mechanism 20 to rise is brought about by the rise of the pull rod structure 50 at the main lifting mechanism 10, and since the pull rod structure 50 is relatively slender, when the pull rod structure 50 at the main lifting mechanism 10 rises, the pull rod at the skid power mechanism 20 may not necessarily be guaranteed to be in the same horizontal position as the pull rod at the main lifting mechanism 10, with a certain deviation. Therefore, the second auxiliary lifting assembly is required to assist the rotation angle of the second lifting link to be the same as that of the first lifting link. Specifically, the tenth rotating shaft at the second connection end 222 is pushed by the second cylinder body 221, thereby causing the second lifting link to rotate. This design structure can ensure that the rotation angles of the first lifting link, the second lifting link, and the third lifting link are the same, and further ensure that the horizontal heights at which the first lifting platform 14, the second lifting platform 24, and the third lifting platform 33 are lifted are the same, so as to ensure that the horizontal heights of all parts of the skid mechanism 40 are the same.

[0050] In summary, the vehicle body conveying system in the above embodiments of the present invention can increase the accuracy of the skid mechanism rising or falling and greatly reduce the conveying time of the vehicle body.

[0051] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.

[0052] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
