Description

Technical Field

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

[0002] When performing electrophoretic coating on the car body, the automobile production factory usually uses a flip conveyor mechanism to convey and flip the car body. The car body is installed on the flip conveyor mechanism, and driven by the flip conveyor mechanism, it moves along the production line with the roof facing up. After reaching the electrophoretic station, the car body is rotated to the top of the electrophoretic pool, flipped to the top facing down and immersed in the electrophoretic pool. After completing the electrophoretic processing, it is flipped again to the top facing up and returns along the production line.

[0003] In the related art, the frame of the flipping conveying mechanism is installed on the guide rail of the production workshop and can move along the guide rail to realize the conveying of the automobile shell. The flipping structure is located on one side of the frame during electrophoresis processing, and cooperates with flipping the automobile shell to complete electrophoresis. For example, the cantilever flipping conveyor and circulating conveying system disclosed in the Chinese patent document with application publication number CN 116216261 A adopts the above method. When the automobile shell is electrophoretically processed in the above method, the movement of the flipping conveying mechanism along the guide rail mainly depends on the power wheel and the 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 movement path setting and state conversion of the device cause the device to have different lengths of rest time at different positions during a back and forth movement. During the rest, a certain position of the limit roller is always subjected to a long period of high pressure, which causes excessive local wear on the circumference of the limit roller. If the limit roller has uneven wear with severe wear in some areas, the roller will lose balance, resulting in unstable movement of the equipment, which may affect the overall operation 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 acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 10 As shown, an embodiment of the present invention provides a factory-use flip conveying mechanism that can assist in completing the electrophoresis processing of a car body, and specifically includes a main frame 100, a guide rail 200, a power walking device 300, and a roller assembly 400.

[0024] The guide rail 200 is installed in the factory, and the main frame 100 can move along the guide rail 200. A rack 110 is provided on the main frame 100, and the rack 110 is used to install the car body. The rack 110 can rotate around the vertical axis and thus can change its left and right position on the main frame 100. The rack 110 can also rotate around the horizontal axis, thereby driving the car body to flip up and down to achieve electrophoresis processing.

[0025] The main frame 100 is a steel structure, which is assembled and welded by steel pipes, channel steels, steel sections, steel plates, etc. Figure 1The main frame 100 is in an I-shaped structure as a whole, and the crossbeam of the I-shaped structure is parallel to the guide rail 200. A rotating arm 120 capable of rotating around a vertical axis is provided on one side of the main frame 100 in the front-to-back direction. The storage rack 110 is installed at the bottom of the rotating arm 120 and can rotate around a horizontal axis relative to the rotating arm 120. A power rotating device is provided inside the rotating arm 120, and the power rotating device is used to drive the rotating arm 120 to rotate and to drive the storage rack 110 to rotate relative to the rotating arm 120. Preferably, the electric pool is located on the front left side of the present invention, and the rotating arm 120 is provided on the rear side of the main frame 100 (that is, the rear side of the vertical beam of the main frame 100, where the front refers to the forward direction of the main frame 100, and the reverse is the rear). When in use, the rotating arm 120 is rotated to make the rack 110 rotate to the right side of the main frame 100, and the car body is transported and installed on the rack 110. Then the main frame 100 moves forward along the guide rail 200. When it moves to the vicinity of the electrophoresis pool, the rotating arm 120 drives the rack 110 to rotate to the left side of the main frame 100 and is located above the electrophoresis pool. The rack 110 flips the car body to face down and immerses it in the electrophoresis pool. Then the main frame 100 returns slowly along the guide rail 200, and cooperates with the small swing of the rack 110 to complete the electrophoresis processing. After the electrophoresis is completed, the rack 110 flips the car body to face up, and the main frame 100 continues to return to the starting point.

[0026] The power traveling device 300 is configured to drive the main frame 100 to move forward and backward along the guide rail 200 .

[0027] 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, and the roller bodies 420 are arranged on the support platform 410. All 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 then roll along the guide rail 200. The adjustment structure is configured to control the roller bodies 420 on the left and right sides to exchange positions, thereby making the wear of the roller bodies 420 more uniform.

[0028] It can be understood that in order to meet the planning requirements of the production line, during the operation of the device, the storage rack 110 drives the car body to be on one side of the main frame 100, that is, the device has an offset structure. The offset structure causes the roller body 420 on one side to be subjected to excessive force. At the same time, because the main frame 100 stays at different workstations for different times during the outbound and return journeys, for example, the device stays for a longer time during electrophoresis processing, which causes the pressure on the roller body 420 to be more uneven. The solution of this embodiment enables the roller bodies 420 on the left and right sides to exchange positions. When in use, the roller bodies 420 on the left and right sides can be set to exchange positions after each running cycle, or to change positions after several cycles, so that the roller bodies 420 on both sides are subject to the same degree of total load for the same time, so that the wear degree of the roller bodies 420 on both sides is as consistent as possible, thereby improving the uniformity of the wear of the roller bodies 420. When the roller bodies 420 are worn evenly, the wear degree will be smaller, which is conducive to the stable operation of the device.

[0029] In a further embodiment, a mounting groove 101 is provided on the main frame 100, and the support platform 410 is slidable up and down and rotatably provided in the mounting groove 101, and 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 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 change positions left and right; The adjustment structure includes a rotating chassis 431, a rotating motor 432 and a power cylinder 433; The rotating chassis 431 is rotatably disposed at the bottom of the mounting groove 101, and the rotating motor 432 is disposed on the main frame 100. 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; The power cylinder 433 is fixedly disposed 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 , so as to be able to drive the support platform 410 to rise and fall, so that the support platform 410 switches between the first position and the second position.

[0030] In the solution of this embodiment, the support platform 410 can be switched between the first position and the second position by setting the power cylinder 433. 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 move normally along the guide rail 200. When the position of the roller body 420 needs to be changed, 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 rotating chassis 431 is driven to rotate by the rotating motor 432, and the rotating 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 switch positions, and 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 be a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or other power elements that can achieve the same function.

[0031] In a further embodiment, the support platform 410 includes a truncated platform 4101 and a polygonal platform 4102 located below the truncated platform 4101, and on a horizontal projection plane, the outer peripheral wall of the truncated platform 4101 is tangent to the outer peripheral wall of the polygonal platform 4102; The mounting groove 101 includes a first groove 1011, a second groove 1012 and a second groove 1012 which are connected and aligned in sequence from top to bottom. The first groove 1011 is a polygonal groove and its shape is adapted to the polygonal platform 4102. The first groove 1011 is configured to hinder the rotation of the polygonal platform 4102 when the polygonal platform 4102 is located inside the first groove 1011, thereby hindering the rotation of the support platform 410. Preferably, the projections of the polygonal platform 4102 and the first groove 1011 on the horizontal plane are both square; the second groove 1012 is configured to allow the polygonal platform 4102 to rotate when the polygonal platform 4102 is located inside the first groove 1011. The polygonal table 4102 rotates, and 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 polygonal table 4102. When the size of the second groove 1012 is a circle, its projection on the horizontal plane is at least circumscribed to the projection of the polygonal table on the horizontal plane. Preferably, the second groove 1012 is set to a circle; the shape of the third groove 1013 can be a polygon or a circle, without limitation. Preferably, the third groove 1013 is a square, and the rotating chassis 431 is set in the third groove 1013.

[0032] When the support platform 410 is in the first position, its polygonal platform 4102 is located in the first groove 1011, and when the support platform 410 is in the second position, its polygonal platform 4102 is located in the second groove 1012; this arrangement ensures that when the device is working normally (the roller body 420 is in contact with the guide rail 200), the support platform 410 cannot rotate, thereby preventing the system from being affected by erroneous operation.

[0033] In a further embodiment, an arc-shaped rotating plate 102 is provided on the main frame 100, and 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 positions of the two groups of roller bodies 420 left and right, the support platform 410 is lowered to the second position. At this time, the roller body 420 is separated 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 friction transmission action with the arc-shaped rotating plate 102, and the initial phase of the roller body 420 is changed, that is, the contact part of the roller body 420 and the guide rail 200 is changed, so that the wear of the roller body 420 is more uniform.

[0034] In a further embodiment, the roller assembly 400 is provided with four roller bodies 420, and the four roller bodies 420 are arranged in groups of two on both sides of the guide rail 200; providing four roller bodies 420 can make the force of the roller assembly 400 more uniform and the device run more smoothly.

[0035] Furthermore, two arc grooves 411 are opened on the upper surface of the truncated table 4101 of the support platform 410. The two arc grooves 411 are concentric with the support platform 410 and symmetrical to each other. The two opposite roller bodies 420 in the two groups of roller bodies 420 are rotatably set in the same arc groove 411 and can slide along the arc groove 411.

[0036] Each roller body 420 is rotatably connected to a hinge rod 442, and 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, and one end of the hinge rod 442 away from the roller body 420 is rotatably connected to the hinge column. A limit plate is commonly connected to the four hinge columns to prevent the hinge rod 442 from detaching from the hinge column from above; two hinge columns are provided on the upper surface of the round table 4101 of the support platform 410 A double-outlet cylinder 441 is provided, and each double-outlet cylinder 441 is connected to two hinged rods 442 on two corresponding roller bodies 420 in the two groups of roller bodies 420. A sliding groove 4421 is provided in the middle of each hinged rod 442. A sliding column 4411 is provided at the end of the output rod of the double-outlet cylinder 441. The sliding column 4411 is rotatably and slidably arranged in the sliding groove 4421, so that the output end of the double-outlet cylinder 441 can slide along the sliding groove 4421 and can rotate around the vertical axis in the sliding groove 4421.

[0037] In the solution of this embodiment, the clamping structure composed of the double-outlet cylinder 441 and the hinge rod 442 can make the roller body 420 conflict with the guide rail 200 during operation. When it needs to move downward to change position, the roller body 420 is first disengaged from the guide rail 200 to avoid 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 along the radial direction of the support platform 410, and a double-outlet cylinder 441 is set to rotatably connect the two roller bodies 420, which can also achieve contact or separation between the roller body 420 and the guide rail 200.

[0038] In a further embodiment, at least the outer portion of the roller body 420 is made of rubber material and can undergo appropriate deformation; a spiral piece 421 is provided inside the roller body 420, the spiral piece 421 is coaxial with the roller body 420 and at least the outer circumference of the spiral piece 421 is in contact with the outer portion of the roller body 420, and two adjusting rods 422 are inserted into the roller body 420, the two adjusting rods 422 are at least partially exposed from the roller body 420 and one end exposed 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 reverse up and down, one end of the two adjusting rods 422 located inside the roller body 420 is respectively connected to the two ends of the spiral piece 421, and one end of the adjusting rod 422 exposed from the roller body 420 is threadedly connected with a nut to lock the position of the adjusting rod 422.

[0039] According to the solution of this embodiment, by providing the spiral piece 421 and the adjusting rod 422, after the roller body 420 is worn, the spiral piece 421 can be compressed toward the middle by pulling the adjusting rod 422 outward, and the compressed spiral piece 421 squeezes the roller body 420 outward, so that the roller body 420 can restore its original roundness as much as possible, thereby extending the service life of the roller body 420.

[0040] In a further embodiment, in order 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, and four roller assemblies 400 are provided. The four roller assemblies 400 are arranged in groups of two on the front and rear sides of the main frame 100, and the two roller assemblies 400 in the same group are aligned up and down and correspond to the upper and lower tracks of the guide rail 200 respectively.

[0041] Specifically, the guide rail 200 is a square column structure with right-angle notches at four corners from front to back, thereby forming two convex tracks and two convex tracks. 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.

[0042] 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.

[0043] In a further embodiment, the power walking device 300 includes a walking motor 310, a first bevel gear 320, a second bevel gear 330, and an output gear 340. The walking motor 310 is arranged on the main frame body 100, and the output shaft of the walking motor 310 is parallel to the guide rail 200; the first bevel gear 320 is connected to the output shaft of the walking motor 310; the second bevel gear 330 and the output gear 340 are both rotatably arranged on the main frame body 100, the second bevel gear 330 and the output gear 340 are coaxially arranged and the axes of both are perpendicular to the extending direction of the guide rail 200, and the second bevel gear 330 meshes with the first bevel gear 320; teeth are provided on the upper surface of the guide rail 200, and the teeth mesh with the output gear 340.

[0044] Furthermore, a gear box is also arranged on the main frame body 100. The first bevel gear 320, the second bevel gear 330, and the output gear 340 are all located inside the gear box. A guide wheel 350 is rotatably arranged on the gear box, and the guide wheel 350 can walk along the guide rail 200 to better support the gear box.

[0045] Furthermore, to make the operation of the device more stable, power walking devices 300 are arranged on both the front and rear sides of the main frame body 100.

[0046] In a further embodiment, a control cabinet 130 is also arranged on the main frame body 100, and the control cabinet 130 is used to control the power components of the device.

[0047] Combining the above embodiments, the working principle and process of the present invention are as follows: When starting work, first install the car body on the rack 110, and rotate the rack 110 to the right side of the main frame 100, start the travel motor 310, the travel 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, the output gear 340 cooperates with the teeth on the guide rail 200 so that the device moves along the guide rail 200. After walking to the electrophoresis station, the rack 110 rotates to the left side of the main frame 100 and is located above the electrophoresis station. The rack 110 drives the car body to flip over to the roof facing down and immerse it in the electrophoresis tank, and the main frame 100 returns along the guide rail 200 to complete the electrophoresis process.

[0048] When the entire device runs one cycle or several cycles, the double-outlet cylinder 441 is started, the two output rods of the double-outlet cylinder 441 extend outward, the angle of the two hinged rods 442 connected to the double-outlet cylinder 441 increases, the roller body 420 slides along the arc groove 411 and moves away from each other, and the roller body 420 is separated from the guide rail 200.

[0049] Afterwards, start the power cylinder 433, which drives the support platform 410 to move downward. When the support platform 410 moves downward 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 rotating motor 432, which drives the rotating chassis 431 to rotate, thereby driving the power cylinder 433, the support platform 410 and the roller body 420 to rotate, so that the roller body 420 exchanges positions left and right. At the same time, when the roller body 420 rotates to contact the arc-shaped rotating plate 102, it will rotate a certain angle under the action of the arc-shaped rotating plate 102 to change the phase, and then start the previous work again to reset all the structures.

[0050] It can be understood that the present invention introduces the specific implementation mode of the present invention by taking the electrophoretic processing of the automobile body as an example, but the present invention is not limited to the electrophoretic processing of the automobile, but is also applicable to the electrophoretic processing of other parts and components. Naturally, it is also applicable to other occasions other than electrophoretic processing where the processed parts need to be flipped and transported.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
