Description

Technical Field

[0001] The present invention relates to the field of conveying mechanisms, in particular to a turnover conveying mechanism for factories. Background Art

[0002] When performing electrophoretic coating on car bodies in automobile production plants, a flip conveyor mechanism is usually used to transport and flip the car bodies. The car bodies are installed on the flip conveyor mechanism and are driven by the flip conveyor mechanism to move along the production line with the roof facing upwards. After reaching the electrophoretic station, the car bodies are rotated above the electrophoretic pool and flipped with the roof facing downwards to be immersed in the electrophoretic pool. After the electrophoretic process is completed, the car bodies are flipped again with the roof facing upwards and returned along the production line.

[0003] In the related art, the frame of a flipping conveyor mechanism is mounted on a guide rail in the production workshop and can move along the rail to transport the automobile body. During electrophoresis processing, the flipping structure is located on one side of the frame and cooperates with flipping the automobile body to complete the electrophoresis. For example, the cantilever flipping conveyor and circulating conveying system disclosed in Chinese Patent Application Publication No. CN 116216261 A adopts this approach. During electrophoresis processing of automobile bodies, the movement of the flipping conveyor mechanism along the guide rail primarily relies on a power wheel and a limit roller. Due to the eccentric cantilever structure of the device, the limit roller on one side is subjected to excessive force. In addition, the device's motion path setting and state transitions result in different lengths of rest time at different positions during the device's back-and-forth movement. During these rest periods, a certain position of the limit roller is subjected to high pressure for a long time, resulting in excessive local wear on the limit roller's circumference. If the limit roller experiences uneven wear, with severe wear in some areas, the roller will lose balance, resulting in unstable movement of the equipment and potentially affecting the overall operating accuracy and efficiency.

[0004] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0054] As Figures 1 to 10 shown, a flipping and conveying mechanism for a factory provided by an embodiment of the present invention can assist in completing the electrophoresis processing of an automobile shell, and specifically includes a main frame 100, a guide rail 200, a power walking device 300, and a roller assembly 400.

[0055] The guide rail 200 is installed in the factory. The main frame 100 can move along the guide rail 200. A storage rack 110 is arranged on the main frame 100. The storage rack 110 is used for installing the automobile shell. The storage rack 110 can rotate around the vertical axis and thus can change its left - right position on the main frame 100. The storage rack 110 can also rotate around the horizontal axis, thereby driving the automobile shell to turn over up and down to realize electrophoretic processing.

[0056] Among them, the main frame 100 is made of steel structure, specifically assembled and welded by steel pipes, channel steels, section steels, steel plates, etc. Refer to Figure 1 , the main frame 100 as a whole presents an I - shaped structure. The cross beam of the I - shaped structure is parallel to the guide rail 200. On one side of the main frame 100 in the front - rear direction, there is a rotating arm 120 that can rotate around the vertical axis. The storage rack 110 is installed at the bottom of the rotating arm 120 and can rotate around the horizontal axis relative to the rotating arm 120. A power rotating device is arranged inside the rotating arm 120. The power rotating device is used to drive the rotation of the rotating arm 120 and to drive the storage rack 110 to rotate relative to the rotating arm 120. Preferably in the present invention, the electrophoresis tank is located at the front left, and the rotating arm 120 is arranged at the rear side of the main frame 100 (that is, on the rear side of the vertical beam of the main frame 100, where the front refers to the advancing direction of the main frame 100, and the opposite is the rear). During use, rotate the rotating arm 120 to make the storage rack 110 rotate to the right side of the main frame 100. The automobile shell is transported and installed on the storage rack 110. Then the main frame 100 advances along the guide rail 200. When advancing near the electrophoresis tank, the rotating arm 120 drives the storage rack 110 to rotate to the left side of the main frame 100 and be located above the electrophoresis tank. The storage rack 110 flips to make the automobile shell face downwards with the roof and immerse it in the electrophoresis tank. Then the main frame 100 slowly returns along the guide rail 200 and cooperates with the small - amplitude swing of the storage rack 110 to complete the electrophoretic processing. After electrophoresis is completed, the storage rack 110 flips the automobile shell to face upwards with the roof, and the main frame 100 continues to return to the starting point.

[0057] The power walking device 300 is configured to drive the main frame 100 to move back and forth along the guide rail 200.

[0058] The roller assembly 400 includes a support platform 410, at least two roller bodies 420 and an adjustment structure. The support platform 410 is installed on the main frame 100. The roller bodies 420 are arranged on the support platform 410. All the roller bodies 420 are divided into two groups and are arranged on the left and right sides of the guide rail 200 in groups. The roller bodies 420 can rotate around their own axes and thus can roll and walk along the guide rail 200. The adjustment structure is configured to be able to control the exchange of positions of the roller bodies 420 on the left and right sides, so that the wear of the roller bodies 420 is more uniform.

[0059] It can be understood that to meet the planning requirements of the production line, during the operation of the device, the storage rack 110 drives the automobile shell to be on one side of the main frame 100, that is, the device belongs to an offset structure. The offset structure causes the roller bodies 420 on one side to be overloaded. At the same time, due to the different residence times of the main frame 100 during the forward and return trips at different workstations, for example, the residence time of the device during electrophoresis processing is obviously longer, which further leads to more uneven pressure on the roller bodies 420. In the solution of this embodiment, by enabling the roller bodies 420 on the left and right sides to exchange positions, during use, it can be set that the roller bodies 420 on the left and right sides change positions every running cycle, or change positions after several cycles, so that the roller bodies 420 on both sides receive the same total load for the same time, making the wear degrees of the roller bodies 420 on both sides as consistent as possible, thereby improving the uniformity of the wear of the roller bodies 420. When the wear of the roller bodies 420 is uniform, the wear degree will be smaller, which is beneficial to the stable operation of the device.

[0060] In a further embodiment, an installation groove 101 is provided on the main frame 100, and the support platform 410 is arranged to be able to slide up and down and rotate in the installation groove 101. The support platform 410 has a first position and a second position in the vertical direction. When the support platform 410 is in the first position, the roller body 420 is aligned with the guide rail 200 and can thus abut against the guide rail 200. When the support platform 410 is in the second position, the roller body 420 is misaligned with the guide rail 200, so that the two groups of roller bodies 420 can be exchanged left and right;

[0061] The adjustment structure includes a rotating chassis 431, a rotating motor 432 and a power cylinder 433;

[0062] The rotating chassis 431 is rotatably arranged at the bottom of the installation groove 101, the rotating motor 432 is arranged on the main frame 100, and the output end of the rotating motor 432 faces upward and is connected to the rotating chassis 431 to drive the rotating chassis 431 to rotate;

[0063] The power cylinder 433 is fixedly arranged on the upper surface of the rotating chassis 431, and the output end of the power cylinder 433 is fixedly connected to the support platform 410 to be able to drive the support platform 410 to lift, so that the support platform 410 can be switched between the first position and the second position.

[0064] In the solution of this embodiment, by setting the power cylinder 433, the support platform 410 can be switched between the first position and the second position. When the device is working normally, the support platform 410 is in the first position, the roller body 420 is in contact with the guide rail 200, and the main frame 100 can walk along the guide rail 200 normally. When the position of the roller body 420 needs to be replaced, the power cylinder 433 drives the roller body 420 to move downward through the support platform 410, so that the roller body 420 is separated from the guide rail 200. At this time, the rotation motor 432 is driven to drive the rotation chassis 431 to rotate. The rotation chassis 431 drives the power cylinder 433, the support platform 410 and the roller body 420 to rotate, so that the two groups of roller bodies 420 are switched in position. Then the power cylinder 433 is lifted so that the roller body 420 is in contact with the guide rail 200 again. It can be understood that the power cylinder 433 can adopt a hydraulic cylinder, a pneumatic cylinder, an electric cylinder and other power elements that can achieve the same function.

[0065] In a further embodiment, the support platform 410 includes a frustum 4101 and a polygon platform 4102 located below the frustum 4101. On the horizontal projection plane, the outer peripheral wall of the frustum 4101 is tangent to the outer peripheral wall of the polygon platform 4102;

[0066] The installation groove 101 includes a first groove 1011, a second groove 1012 and a third groove 1013 that are connected and aligned in sequence from top to bottom. The first groove 1011 is a polygon groove and its shape is adapted to the polygon platform 4102. The first groove 1011 is configured to prevent the polygon platform 4102 from rotating when the polygon platform 4102 is inside it, and thus prevent the support platform 410 from rotating. Preferably in the present invention, the projections of the polygon platform 4102 and the first groove 1011 on the horizontal plane are both squares; the second groove 1012 is configured to allow the polygon platform 4102 to rotate when the polygon platform 4102 is located inside it. The shape of the second groove 1012 can be a polygon or a circle. When the second groove 1012 is a polygon, its size is larger than the size of the polygon platform 4102. When the size of the second groove 1012 is a circle, its projection on the horizontal plane circumscribes at least the projection of the polygon platform 4102 on the horizontal plane. Preferably in the present invention, the second groove 1012 is set as a circle; the shape of the third groove 1013 can be a polygon or a circle, which is not limited. Preferably in the present invention, the third groove 1013 is a square, and the rotation chassis 431 is arranged in the third groove 1013.

[0067] When the support platform 410 is in the first position, its polygon platform 4102 is located in the first groove 1011. When the support platform 410 is in the second position, its polygon platform 4102 is in the second groove 1012; such a setting makes the support platform 410 unable to rotate when the device is working normally (the roller body 420 is in contact with the guide rail 200), avoiding the influence of system misoperation on the device.

[0068] In a further embodiment, an arc-shaped rotating plate 102 is provided on the main frame body 100. The arc-shaped rotating plate 102 is located outside the roller body 420. When the support platform 410 is in the second position, the roller body 420 is in frictional contact with the arc-shaped rotating plate 102. When it is necessary to exchange the left and right positions of the two sets of roller bodies 420, the support platform 410 descends to the second position. At this time, the roller body 420 disengages from the guide rail 200 and is in frictional contact with the arc-shaped rotating plate 102. During the rotation of the support platform 410, the roller body 420 rotates around its own axis under the frictional driving action of the arc-shaped rotating plate 102, changing the initial phase of the roller body 420, that is, changing the contact part between the roller body 420 and the guide rail 200, so that the wear of the roller body 420 is more uniform.

[0069] In a further embodiment, the roller assembly 400 is provided with four roller bodies 420. The four roller bodies 420 are divided into two groups and are arranged on both sides of the guide rail 200 in pairs; setting four roller bodies 420 can make the force on the roller assembly 400 more uniform and the device run more smoothly.

[0070] Further, two arc-shaped grooves 411 are formed on the upper surface of the conical platform 4101 of the support platform 410. The two arc-shaped grooves 411 are both concentric with the support platform 410 and symmetric with each other. Two opposite roller bodies 420 in the two sets of roller bodies 420 are rotatably arranged in the same arc-shaped groove 411 and can slide along the arc-shaped groove 411.

[0071] A hinge rod 442 is rotatably connected to each roller body 420. One end of the hinge rod 442 away from the roller body 420 points to the center of the support platform 410 and is rotatably connected to the support platform 410. Specifically, four hinge columns are provided on the upper surface of the support platform 410. One end of the hinge rod 442 away from the roller body 420 is rotatably connected to the hinge column. A limiting piece is commonly connected to the four hinge columns to prevent the hinge rod 442 from disengaging from the hinge column from above; two double-acting cylinders 441 are provided on the upper surface of the conical platform 4101 of the support platform 410. Each double-acting cylinder 441 is connected to two hinge rods 442 on two corresponding roller bodies 420 in the two sets of roller bodies 420. A sliding groove 4421 is provided in the middle of each hinge rod 442. The end of the output rod of the double-acting cylinder 441 is provided with a sliding column 4411. The sliding column 4411 can rotate and can slide in the sliding groove 4421, so that the output end of the double-acting cylinder 441 can slide along the sliding groove 4421 and can rotate around the vertical axis in the sliding groove 4421.

[0072] In the solution of this embodiment, the clamping structure composed of the double-acting cylinder 441 and the articulated rod 442 enables the roller body 420 to contact the guide rail 200 during operation. When it is necessary to move downward to change the position, the roller body 420 first disengages from the guide rail 200, avoiding friction between the roller body 420 and the guide rail 200. In other embodiments, it is also feasible to set the roller assembly 400 to include two roller bodies 420. When there are two roller bodies 420, the roller bodies 420 can be set to slide radially along the support table 410, and a double-acting cylinder 441 can be rotationally connected to the two roller bodies 420 to also achieve the contact or disengagement of the roller body 420 and the guide rail 200.

[0073] In a further embodiment, at least the outer part of the roller body 420 is made of a rubber material and can undergo appropriate deformation; a spiral piece 421 is arranged inside the roller body 420. The spiral piece 421 is coaxial with the roller body 420 and at least the outer periphery of the spiral piece 421 contacts the outer part of the roller body 420. Two adjusting rods 422 are inserted into the roller body 420. At least part of the two adjusting rods 422 protrudes from the roller body 420, and one end of the adjusting rod 422 protruding from the roller body 420 is provided with a thread. The two adjusting rods 422 are respectively located on both sides of the roller body 420 and are arranged in opposite directions up and down. One end of the two adjusting rods 422 located inside the roller body 420 is respectively connected to both ends of the spiral piece 421. A nut is threadedly connected to the end of the adjusting rod 422 protruding from the roller body 420 to lock the position of the adjusting rod 422.

[0074] In the solution of this embodiment, through the arrangement of the spiral piece 421 and the adjusting rod 422, after the roller body 420 is worn, by pulling out the adjusting rod 422 outward, the spiral piece 421 can be compressed towards the middle. The compressed spiral piece 421 squeezes the roller body 420 outward, enabling the roller body 420 to recover as much as possible to its original roundness and extending the service life of the roller body 420.

[0075] In a further embodiment, to ensure the force balance of the device and make the operation of the device more stable, two upper and lower tracks are formed on the guide rail 200. Four roller assemblies 400 are provided. The four roller assemblies 400 are arranged in two groups on the front and rear sides of the main frame 100. The two roller assemblies 400 in the same group are vertically aligned and respectively correspond to the two upper and lower tracks of the guide rail 200.

[0076] Specifically, the guide rail 200 is an overall square column structure, and right-angled notches are opened at all four corners from front to back, thereby forming two upper and lower convex tracks. More specifically, referring to Figure 1, mounting brackets are provided at both the front and rear ends of the upper crossbeam of the main frame body 100. The mounting brackets are integrally in a U-shaped structure. Specifically, the mounting brackets have a top plate, a bottom plate, and a vertical plate connected between the top plate and the bottom plate and located on one side of the top plate and the bottom plate. The guide rail 200 is inserted between the top plate and the bottom plate of the mounting bracket, and two roller assemblies 400 in the same group are respectively arranged on the top plate and the bottom plate of the mounting bracket and are arranged oppositely.

[0077] In a further embodiment, the size of the roller body 420 is configured to run an integer number of circles along the guide rail 200 from the starting point to the end point. With such a setting, during the running process of the roller body 420, its outer circumference will be subjected to pressure at equal time intervals, thereby further making the force on the roller body 420 uniform.

[0082] Combined with the above embodiments, the usage principle and working process of the present invention are as follows:

[0083] When starting to work, first install the car shell on the storage rack 110, rotate the storage rack 110 to the right side of the main frame 100, start the traveling motor 310, the traveling motor 310 drives the first bevel gear 320 to rotate, the first bevel gear 320 drives the second bevel gear 330 to rotate, the second bevel gear 330 drives the output gear 340 to rotate, and the output gear 340 cooperates with the teeth on the guide rail 200 to make the device travel along the guide rail 200. After traveling to the electrophoresis station, the storage rack 110 rotates to the left side of the main frame 100 and is located above the electrophoresis station. The storage rack 110 drives the car shell to flip so that the roof is facing down and is immersed in the electrophoresis tank. The main frame 100 returns along the guide rail 200 to complete the electrophoresis processing.

[0084] When the entire device runs for one cycle or several cycles, start the double-acting cylinder 441. The two output rods of the double-acting cylinder 441 extend outwards, the angles of the two articulated rods 442 connected to the double-acting cylinder 441 become larger, the roller bodies 420 slide along the arc-shaped groove 411 and move away from each other, and the roller bodies 420 are disengaged from the guide rail 200.

[0085] After that, start the power cylinder 433. The power cylinder 433 drives the support platform 410 to move downwards. When the support platform 410 moves down to the second position, that is, when the polygonal platform 4102 of the support platform 410 is located in the second groove 1012, start the rotary motor 432. The rotary motor 432 drives the rotary chassis 431 to rotate, thereby driving the power cylinder 433, the support platform 410 and the roller bodies 420 to rotate, so that the roller bodies 420 exchange positions left and right. At the same time, when the roller bodies 420 rotate and contact the arc-shaped rotating plate 102, they will rotate a certain angle under the action of the arc-shaped rotating plate 102 to change the phase. Then start the previous work and reset all the structures.

[0086] It can be understood that the present invention introduces the specific implementation manner of the present invention by taking the electrophoresis processing of the car shell as an example. However, the present invention is not limited to the electrophoresis processing of cars, and the electrophoresis processing of other parts is equally applicable. Naturally, it is also applicable to other occasions that require flipping and conveying of the processed parts other than electrophoresis processing.

[0087] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
