Description

Technical Field

[0001] This invention relates to the field of assembly line equipment technology, and in particular to a workpiece flipping and reversing support structure for assembly lines. Background Technology

[0002] In industrial production, the transfer and reversing of workpieces on assembly lines is a crucial aspect of automated production. Especially in fields such as automobile manufacturing, electronics assembly, and machining, workpieces often require 180° rotation using assembly line workpiece flipping and reversing support structures during transport to meet the needs of subsequent processing, inspection, or assembly.

[0003] While existing assembly line workpiece flipping and reversing support structures can complete the flipping action, they often cannot guarantee the positional accuracy of the workpiece during the flipping process and cannot actively adjust the position of the workpiece. As a result, the workpiece is prone to deviating from the center position of the conveyor belt after flipping, which can easily lead to the workpiece falling off and affect the stability and continuity of the production line. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a workpiece flipping and reversing support structure for assembly lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a workpiece flipping and reversing support structure for an assembly line, comprising a frame, a conveyor belt movably connected to the inner side of the frame, a drive device fixedly connected to the left side inside the frame, a rotating device fixedly connected to the middle of the front side of the frame, a flipping device fixedly connected to the outer side of the rotating device, fixed cylinders fixedly connected to both the front and rear sides inside the frame, a reciprocating telescopic device fixedly connected inside the fixed cylinder, a push column fixedly connected to the side of the reciprocating telescopic device near the center of the frame, the reciprocating telescopic device including an inner cylinder fixedly connected inside the fixed cylinder, a movable sleeve movably connected to the outer side of the inner cylinder, a telescopic column fixedly connected to the side of the movable sleeve near the fixed cylinder, a vertical column fixedly connected to the side of the telescopic column near the fixed cylinder, a horizontal column fixedly connected to the top of the vertical column, a ball bearing movably connected to the outer end of the horizontal column, a spring column fixedly connected to the side of the inner cylinder away from the fixed cylinder, a clamping spring fixedly connected between the inner cylinder and the movable sleeve, and a connecting plate fixedly connected to the lower part of the movable sleeve.

[0006] Further: The frame includes a frame body, with enclosed shells fixedly connected to both the front and rear sides of the frame body, and support columns fixedly connected to the lower part of the frame body. Connecting columns are fixedly connected between the left and right support columns, and fixing columns are fixedly connected between the connecting columns.

[0007] Further: The conveyor belt includes a rotating column movably connected to the inside of the frame, a rotating drum fixedly connected to the outside of the rotating column, a belt body movably connected to the outside of the rotating drum, and a driven pulley fixedly connected to the front end of the rotating column on the left side.

[0008] Further: The drive device includes a drive motor fixedly connected to the left side inside the frame, the output end of the drive motor is fixedly connected to a drive pulley, and a transmission belt is movably connected to the outer side of the drive pulley.

[0009] Furthermore, the rotating device includes a geared motor fixedly connected to the front side of the frame, and a rotating rod fixedly connected to the output end of the geared motor. Both the front and rear sides of the outer side of the rotating rod are fixedly connected to a drive gear.

[0010] Further: The fixed cylinder includes an outer cylinder fixedly connected to the front and rear sides inside the frame, a rotating column is movably connected inside the outer cylinder, a helical wheel is fixedly connected to the inner end of the rotating column, and a driven gear is fixedly connected to the outer end of the rotating column.

[0011] Further: The push column includes a column body fixedly connected to the side of the reciprocating telescopic device near the center of the frame. The column body is internally threaded with a screw rod. A connecting block is fixedly connected to the end of the screw rod away from the column body. A protective pad is fixedly connected to the side of the connecting block away from the screw rod.

[0012] Further: The flipping device includes a connecting cylinder fixedly connected to the outside of the rotating device, a rotating plate fixedly connected to the outside of the connecting cylinder, a rotating shaft movably connected to the inside of the rotating plate, and a rotating cylinder movably connected to the outside of the rotating shaft.

[0013] The present invention has the following beneficial effects:

[0014] 1. Compared with the prior art, this workpiece flipping and reversing support structure for assembly lines, by incorporating a reciprocating telescopic device, push column, and fixed cylinder, facilitates the active adjustment of the workpiece position. When the reduction motor is started to flip the workpiece, the driven gear drives the rotating column, causing the inclined wheel to rotate, which in turn causes the telescopic column to move back and forth. This, in turn, drives the moving sleeve, causing the connecting plate to move back and forth, which in turn causes the push columns on both the front and rear sides to move simultaneously towards the center and sides. This pushes the workpiece so that it is positioned in the middle of the conveyor belt, preventing the workpiece from deviating from the center and easily falling off, thus ensuring the stability and continuity of the production line.

[0015] 2. Compared with the prior art, this assembly line workpiece flipping and reversing support structure, by having a flipping device, facilitates the flipping of workpieces. Starting the reduction motor enables the rotating rod to drive the connecting cylinder to rotate, which in turn drives the rotating plate to rotate. The rotation of the rotating plate can then flip the workpieces located between adjacent rotating plates, facilitating subsequent assembly of the workpieces. Furthermore, the rotating shaft can rotate inside the rotating plate, while the rotating cylinder can rotate outside the rotating shaft, ensuring that the workpieces can more easily enter and leave between adjacent rotating plates under the drive of the conveyor belt.

[0025] Reference Figure 1-7This invention provides a workpiece flipping and reversing support structure for an assembly line: It includes a frame 1, a conveyor belt 2 movably connected to the inner side of the frame 1, a drive device 3 fixedly connected to the left side inside the frame 1, a rotating device 4 fixedly connected to the middle of the front side of the frame 1, a flipping device 8 fixedly connected to the outer side of the rotating device 4, fixed cylinders 5 fixedly connected to both the front and rear sides inside the frame 1, a reciprocating telescopic device 7 fixedly connected inside the fixed cylinder 5, a push column 6 fixedly connected to the side of the reciprocating telescopic device 7 near the center of the frame 1, the reciprocating telescopic device 7 including an inner cylinder 701 fixedly connected inside the fixed cylinder 5, a movable sleeve 708 movably connected to the outer side of the inner cylinder 701, the movable sleeve 708 being movable to the outer side of the inner cylinder 701, and the movable sleeve 708 being close to... A telescopic column 702 is fixedly connected to the side near the fixed cylinder 5. The telescopic column 702 can move inside the inner cylinder 701. A vertical column 703 is fixedly connected to the side of the telescopic column 702 near the fixed cylinder 5. A horizontal column 705 is fixedly connected to the top of the vertical column 703. A ball bearing 704 is movably connected to the outer end of the horizontal column 705. The ball bearing 704 can roll inside the horizontal column 705, making it easier for the inclined wheel 503 to drive the telescopic column 702 to move back and forth. A spring column 706 is fixedly connected to the side of the inner cylinder 701 away from the fixed cylinder 5. The spring column 706 is used to guide the compression and extension of the clamping spring 709, and the spring column 706 can move inside the telescopic column 702. A clamping spring is fixedly connected between the inner cylinder 701 and the movable sleeve 708. Spring 709, the tension spring 709 is always in a compressed state. Under the action of the tension spring 709, the moving sleeve 708 can drive the telescopic column 702, which in turn drives the vertical column 703 and the horizontal column 705, so that the ball 704 can always be in contact with the inclined wheel 503. The lower part of the moving sleeve 708 is fixedly connected to the connecting plate 707. In use, by starting the drive motor 301, the conveyor belt 2 is driven to transport the workpiece from left to right to the position close to the flipping device 8. At the same time, the reduction motor 401 is started to make the rotating rod 403 rotate, which in turn drives the connecting cylinder 801 to make the rotating plate 802 rotate. The rotation direction of the rotating plate 802 is the same as the rotation direction of the conveyor belt 2. The workpiece can enter the adjacent rotating plate through the continuous conveyor belt 2. Between the rotating plates 802, the workpiece can be flipped and moved to the next process by the conveyor belt 2 as the rotating plate 802 rotates. The rotation of the rotating rod 403 can drive the drive gear 402 to rotate. The drive gear 402 meshes with the driven gear 502. The rotation of the drive gear 402 can drive the driven gear 502 to rotate. The rotation of the driven gear 502 can drive the rotating column 501 to rotate the inclined wheel 503. The inclined wheel 503 is set at an angle. As the inclined wheel 503 rotates, under the action of the clamping spring 709, the telescopic column 702 can move back and forth, which in turn drives the moving sleeve 708 to move the connecting plate 707 back and forth, which in turn drives the push column 6 to push the workpiece towards the center.This ensures the workpiece is positioned in the center of conveyor belt 2, preventing it from shifting off-center and falling off, thus guaranteeing the stability and continuity of the production line.

[0026] Preferably, the frame 1 includes a frame body 101, with enclosed shells 102 fixedly connected to both the front and rear sides of the frame body 101. A support column 104 is fixedly connected to the lower part of the frame body 101, and a connecting column 103 is fixedly connected between the left and right support columns 104. A fixing column 105 is fixedly connected between the connecting columns 103. The enclosed shell 102 is used to enclose the internal drive gear 402 and driven gear 502 to prevent external dust from affecting the rotation of the drive gear 402 and driven gear 502.

[0027] Preferably, the conveyor belt 2 includes a rotating column 201 movably connected to the inner side of the frame 1, a rotating drum 202 fixedly connected to the outer side of the rotating column 201, a belt body 203 movably connected to the outer side of the rotating drum 202, and a certain distance between adjacent rotating drums 202 and belt bodies 203 for the passage of rotating plates 802. A driven pulley 204 is fixedly connected to the front end of the left rotating column 201, and the driven pulley 204 is movably connected to the transmission belt 303.

[0028] Preferably, the drive device 3 includes a drive motor 301 fixedly connected to the left side inside the frame 1. The output end of the drive motor 301 is fixedly connected to a drive pulley 302. A transmission belt 303 is movably connected to the outer side of the drive pulley 302. Starting the drive motor 301 causes the drive pulley 302 to drive the transmission belt 303 to rotate, which in turn drives the driven pulley 204 to drive the rotating column 201 to drive the rotating drum 202 to rotate, thereby driving the belt body 203 to transport the workpiece.

[0029] Preferably, the rotating device 4 includes a geared motor 401 fixedly connected to the front side of the frame 1. The output end of the geared motor 401 is fixedly connected to a rotating rod 403. Both the front and rear sides of the outer side of the rotating rod 403 are fixedly connected to a drive gear 402. The number of teeth of the drive gear 402 is four times the number of teeth of the driven gear 502. When the drive gear 402 rotates 90 degrees, the driven gear 502 rotates one revolution, ensuring that the workpiece can be pushed by the push column 6 after flipping, so that the workpiece can be in the center position of the conveyor belt 2.

[0030] Preferably, the fixed cylinder 5 includes an outer cylinder 504 fixedly connected to the front and rear sides inside the frame 1. A rotating column 501 is movably connected inside the outer cylinder 504. A slanted wheel 503 is fixedly connected to the inner end of the rotating column 501. The rotating column 501 and the slanted wheel 503 can rotate inside the outer cylinder 504. A driven gear 502 is fixedly connected to the outer end of the rotating column 501. The driven gear 502 meshes with the driving gear 402.

[0031] Preferably, the push column 6 includes a column 601 fixedly connected to the reciprocating telescopic device 7 on the side near the center of the frame 1. A screw 604 is threadedly connected inside the column 601. The screw 604 can move back and forth inside the column 601 by rotating forward and backward. A connecting block 602 is fixedly connected to the end of the screw 604 away from the column 601. A protective pad 603 is fixedly connected to the side of the connecting block 602 away from the screw 604. The protective pad 603 is made of rubber and is used to ensure that the workpiece is not scratched when pushing it. The screw 604 can be rotated by turning the connecting block 602. The screw 604 can move back and forth inside the column 601 by rotating forward and backward, thereby changing the position of the protective pad 603. This allows the position of the protective pad 603 to be adjusted according to the width of the workpiece.

[0032] Preferably, the flipping device 8 includes a connecting cylinder 801 fixedly connected to the outside of the rotating device 4, a rotating plate 802 fixedly connected to the outside of the connecting cylinder 801, a rotating shaft 803 movably connected to the inside of the rotating plate 802, and a rotating cylinder 804 movably connected to the outside of the rotating shaft 803. The rotating shaft 803 can rotate inside the rotating plate 802, and the rotating cylinder 804 can rotate outside the rotating shaft 803, ensuring that the workpiece can more easily enter and leave between adjacent rotating plates 802 under the drive of the conveyor belt 2.

[0033] Working Principle: During operation, starting the drive motor 301 causes the drive pulley 302 to rotate the transmission belt 303, which in turn drives the driven pulley 204, causing the rotating column 201 to rotate the rotating drum 202. This, in turn, causes the belt body 203 to transport the workpiece from left to right towards the flipping device 8. Simultaneously, starting the reduction motor 401 causes the rotating rod 403 to rotate, which in turn drives the connecting cylinder 801, causing the rotating plate 802 to rotate. The rotation direction of the rotating plate 802 is the same as that of the conveyor belt 2. The conveyor belt 2 continuously transports the workpiece between adjacent rotating plates 802. As the rotating plate 802 rotates, it flips the workpiece and moves it to the next process via the conveyor belt 2. The rotation of the rotating rod 403 drives the drive gear 402 to rotate. The drive gear 402 meshes with the driven gear 502. The rotation of the drive gear 402 drives the driven gear 502 to rotate. The rotation of the driven gear 502 drives the rotating column 501, which in turn drives the inclined wheel 503 to rotate. The inclined wheel 503 is set at an angle. As the inclined wheel 503 rotates and under the action of the clamping spring 709, the telescopic column 702 can move back and forth. This drives the moving sleeve 708, which in turn drives the connecting plate 707 to move back and forth. This drives the push column 6 to push the workpiece towards the center, so that the workpiece is in the middle position of the conveyor belt 2, preventing the workpiece from deviating from the center and falling easily, thus ensuring the stability and continuity of the production line.
