Description

Technical Field

[0001] This utility model relates to the technical field of placing opposing parts on a tape into a tape weaving system, and in particular to an opposing parts packaging machine that integrates cutting, inspection and variable pitch. Background Technology

[0002] The structure with material attached produced in a certain workshop is as follows Figure 1 As shown, the strip includes two parallel frame 1s. Multiple sets of opposing parts are arranged between the left frame 1 and the right frame 1 and spaced apart along their length. Each set of opposing parts includes two L-shaped thin plates 2. The long plates of the two L-shaped thin plates 2 are arranged diagonally. The left and right outer edges of the two L-shaped thin plates 2 are connected to the two frame 1s via a carrier 3.

[0003] The process requires that all opposing parts of the tape be placed in the same direction into the tape tray of the tape machine to complete the packaging of the opposing parts. The specific packaging method is as follows:

[0004] S1. The worker cuts off all the opposing parts of the material using a cutting die. After cutting, the worker puts all the opposing parts into the basket. At this time, the basket contains multiple L-shaped thin plates 2.

[0005] S2. The worker takes an L-shaped thin plate 2 from the material basket and places it on the inspection table of the laser scanner. The top surface of the L-shaped thin plate 2 is scanned by the laser scanner. If the flatness of the L-shaped thin plate 2 does not meet the requirements during the inspection, the worker determines that the L-shaped thin plate 2 is a defective product and removes it.

[0006] If the flatness of the L-shaped thin plate 2 meets the requirements after inspection, the worker will determine that the inspected L-shaped thin plate 2 is a qualified product and put the qualified product into the finished product basket.

[0007] S3. Repeat step S2 multiple times to complete the flatness inspection of all L-shaped thin plates 2 in the material frame. At this time, the finished product basket contains only qualified products.

[0008] S4. Workers place each qualified product from the finished product basket into the tape of the tape feeding machine in sequence, ensuring that each qualified product is placed in the same direction. Figure 2 The diagram shows multiple qualified products arranged in the same direction within the tape, thus completing the packaging of each group of opposing parts on the tape.

[0009] However, while the operating methods in the workshop can package the opposing groups of parts on the conveyor belt, the following technical problems still emerge in actual operation:

[0010] I. In step S2, workers need to manually place all the L-shaped thin plates 2 in the material basket one by one onto the inspection table of the laser scanner. After the flatness is inspected, workers also need to manually put the qualified products into the finished product basket. Both of these processes are done manually by workers, which not only increases the workload of workers, but also delays the packaging of the L-shaped thin plates 2, thereby reducing the packaging efficiency of the opposite parts.

[0011] II. In step S4, workers need to manually put the qualified products in the finished product basket one by one into the tape of the tape machine, and also adjust the orientation of the qualified products to make the placement of each qualified product consistent. The entire operation is done manually by the workers, which further increases the workload of the workers.

[0012] Therefore, there is an urgent need for a packaging machine that can greatly reduce the workload of workers and greatly improve the packaging efficiency of opposite parts. Utility Model Content

[0013] The purpose of this invention is to overcome the shortcomings of the prior art and provide a packaging machine for opposing parts that integrates cutting, inspection and variable distance, which greatly reduces the labor intensity of workers and greatly improves the packaging efficiency of opposing parts.

[0014] The purpose of this utility model is achieved through the following technical solution: a counter-rotating parts packaging machine integrating cutting, inspection and pitch changing, which includes a worktable. On the worktable, from left to right, a cutting mold, a pitch changing component, a flatness inspection component, a direction adjustment component and a tape feeding machine are arranged in sequence. A discharge groove is opened on the top surface of the cutting mold. The pitch changing component includes a longitudinally arranged bidirectional lead screw module. The positive and negative external threads of the lead screw of the bidirectional lead screw module are respectively connected to moving seats. The top surfaces of the two moving seats are each equipped with a receiving platform, and the two receiving platforms are in contact with each other.

A first suction cup and a second suction cup are fixed on the bottom surface of the two connecting frames, respectively. Two suction heads A that communicate with the inner cavity of the first suction cup are fixed on the bottom surface of the first suction cup. Both suction heads A are located directly above the discharge groove of the cutting mold. Two suction heads B that communicate with the inner cavity of the second suction cup are fixed on the bottom surface of the second suction cup. The longitudinal distance between the two suction heads B is equal to the distance between the two through grooves.

[0017] The top surfaces of the two receiving platforms are flush.

[0018] The tapes on the tape machine are arranged longitudinally.

[0019] The connector of the first suction cup is connected to the working port of the first vacuum pump via a pipe; the connector of the second suction cup is connected to the working port of the second vacuum pump via a pipe.

[0020] The workbench is also equipped with discharge guide rails and feed guide rails located on the front and rear sides of the cutting mold, respectively. Both discharge guide rails and feed guide rails are connected to the cutting station of the cutting mold.

[0021] The packaging machine also includes a controller, which is electrically connected to a bidirectional lead screw module, a vertical motor, a tape feeder, a robotic arm, a laser scanner, a first vacuum pump, and a second vacuum pump via signal lines.

[0039] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0040] like Figures 3-8 As shown, a counter-rotating parts packaging machine integrating cutting, inspection, and pitch adjustment is provided. It includes a worktable 4, on which a cutting mold 5, a pitch adjustment assembly 6, a flatness inspection assembly 7, a direction adjustment assembly 8, and a tape feeding machine 9 are arranged sequentially from left to right. The tape feeding machine 9 is arranged longitudinally. A discharge groove 10 is provided on the top surface of the cutting mold 5. The pitch adjustment assembly 6 includes a longitudinally arranged bidirectional lead screw module 11. The lead screw 12 of the bidirectional lead screw module 11 is connected to a moving seat on the positive and negative external threads, respectively. The top surfaces of the two moving seats are each provided with a receiving platform 13, and the two receiving platforms 13 are in contact with each other. The top surfaces of the two receiving platforms 13 are flush.

[0041] The flatness detection component 7 includes a platform 14 fixed on the workbench 4. Two through slots 15 are formed on the surface of the platform 14, and laser scanners are fixed directly below the two through slots 15 respectively. The direction adjustment component 8 includes two vertical motors 16 fixed on the workbench 4. Turntables 17 are fixed on the output shafts of the two vertical motors 16. The longitudinal distance between the two turntables 17 is equal to the longitudinal distance between the two through slots 15.

[0042] The workbench 4 is also equipped with a robotic arm 18 located behind the flatness detection component 7. Two connecting frames 20 are fixed on the front end of the movable rod 19 of the robotic arm 18. A first suction cup 21 and a second suction cup 22 are fixed on the bottom surface of the two connecting frames 20 respectively. Two suction heads A23 connected to the inner cavity of the first suction cup 21 are fixed on the bottom surface of the first suction cup 21. Both suction heads A23 are located directly above the discharge groove 10 of the cutting mold 5. Two suction heads B24 connected to the inner cavity of the second suction cup 22 are fixed on the bottom surface of the second suction cup 22. The longitudinal distance between the two suction heads B24 is equal to the distance between the two through grooves 15.

[0043] The connector of the first suction cup 21 is connected to the working port of the first vacuum pump via a pipe; the connector of the second suction cup 22 is connected to the working port of the second vacuum pump via a pipe. The workbench 4 is also provided with a discharge guide rail 25 and a feed guide rail 26 located on the front and rear sides of the cutting mold 5, respectively. Both the discharge guide rail 25 and the feed guide rail 26 are connected to the cutting station of the cutting mold.

[0044] The packaging machine also includes a controller, which is electrically connected to the bidirectional lead screw module 11, vertical motor 16, tape feeding machine 9, robotic arm 18, laser scanner, first vacuum pump and second vacuum pump via signal lines. The controller can control the vertical motor 16, first vacuum pump, second vacuum pump and bidirectional lead screw module 11 to start or stop, and can also control the robotic arm 18 to run or stop.

[0045] The method for placing all groups of opposing parts of the tape into the tape tray of the tape tray 9 in the same direction is as follows:

[0046] S1, the worker takes out a... Figure 1 The strip shown is fed into the feed guide 26, then the strip is passed through the cutting station of the cutting die 5, and then the strip is pulled into the discharge guide 25. After pulling, the first set of opposing parts on the strip is ensured to be at the cutting station of the cutting die 5.

[0047] S2. The piston rod of the blanking cylinder of the cutting mold extends upward, and the piston rod drives the cutter to move upward. The cutter cuts off the two L-shaped thin plates 2 of the first set of opposing parts with material, and presses the two L-shaped thin plates 2 against the bottom surface of the two suction heads A23 of the robotic arm 18 respectively.

[0048] S3. Control the start of the first vacuum pump. The first vacuum pump creates a vacuum in the inner cavity of the first suction cup 21 and the two suction heads A23. Under negative pressure, the two L-shaped thin plates 2 are respectively adsorbed and fixed on the two suction heads A23.

[0049] S4. Control the movement of the robotic arm 18. The robotic arm 18 drives the movable rod 19 to move, and the movable rod 19 drives the two connecting frames 20 to move to the right, which in turn drives the first suction cup 21 and the second suction cup 22 to move to the right synchronously. The first suction cup 21 drives the two suction heads A23 to move to the right synchronously, and the two suction heads A23 respectively drive the two L-shaped thin plates 2 to move to the right synchronously. When the two L-shaped thin plates 2 move directly above the two receiving platforms 13 of the pitch component 6, the controller controls the robotic arm 18 to shut down, and then controls the first vacuum pump to shut down. At this time, the two L-shaped thin plates 2 fall onto the top surfaces of the two receiving platforms 13 of the pitch component 6, as shown. Figure 9 As shown;

[0050] S5. The servo motor of the control pitch component 6 starts, driving the lead screw 12 to rotate. The two moving seats on the lead screw 12 move in opposite directions. Simultaneously, the two moving seats drive the receiving platform 13 connected to them to move in opposite directions. The two receiving platforms 13 drive the L-shaped thin plates 2 on them to move in opposite directions, thereby gradually increasing the distance between the two L-shaped thin plates 2. When the servo motor runs for a set time, the controller controls the servo motor to turn off, thereby increasing the distance between the two L-shaped thin plates 2. Figure 10 As shown;

[0051] S6. Control the movement of the robotic arm 18. The robotic arm 18 drives the movable rod 19 to move. The movable rod 19 drives the second suction cup 22 to move towards the variable pitch assembly 6. The second suction cup 22 drives the two suction heads B24 on it to move towards the two L-shaped thin plates 2 that have been changed pitch. When the two suction heads B24 come into contact with the top surfaces of the two L-shaped thin plates 2, the controller controls the robotic arm 18 to close. Then, the controller controls the second vacuum pump to start. The second vacuum pump evacuates the inner cavity of the second suction cup 22 and the two suction heads B24. Under negative pressure, the two L-shaped thin plates 2 are adsorbed and fixed on the two suction heads B24.

[0052] S7. Control the movement of the robotic arm 18. The robotic arm 18 drives the movable rod 19 to move to the right. The movable rod 19 drives the second suction cup 22 to move towards the flatness detection component 7, and then drives the two L-shaped thin plates 2 to move towards the platform 14 of the flatness detection component 7 respectively. When the two L-shaped thin plates 2 move directly above the two through slots 15 of the platform 14 respectively, control the robotic arm 18 to close, and then control the second vacuum pump to close. At this time, the two L-shaped thin plates 2 fall directly above the two through slots 15 respectively.

[0053] As can be seen from steps S6 to S7, the packaging machine can automatically place two L-shaped thin plates 2 onto the platform 14 of the flatness detection component 7 through the two suction heads B24 of the robotic arm 18, eliminating the need for manual placement of the L-shaped thin plates 2 onto the platform 14 one by one. This not only greatly reduces the workload of workers, but also shortens the packaging time of the opposing parts, thereby greatly improving the packaging efficiency of the opposing parts.

[0054] S8. Control the two laser scanners to start. The two laser scanners will detect the flatness of the bottom surface of the two L-shaped thin plates 2 respectively. If the flatness of one of the two L-shaped thin plates 2 does not meet the requirements, the worker will manually remove both L-shaped thin plates 2 from the platform 14 and put them into the temporary storage basket for temporary storage.

[0055] If the flatness of the two L-shaped thin plates 2 meets the requirements, the robotic arm 18 is controlled to move. The robotic arm 18 drives the movable rod 19 to move towards the platform 14. The movable rod 19 drives the second suction cup 22 to move towards the platform 14, which in turn drives the two suction heads B24 to move towards the two L-shaped thin plates 2 respectively. When the two suction heads B24 come into contact with the top surfaces of the two L-shaped thin plates 2 respectively, the second vacuum pump is started. At this time, the two L-shaped thin plates 2 are respectively adsorbed and fixed on the two suction heads B24.

[0056] S9. Control the movement of the robotic arm 18. The robotic arm 18 drives the movable rod 19 to move to the right. The movable rod 19 drives the second suction cup 22 to move towards the direction adjustment component 8, which in turn drives the two L-shaped thin plates 2 to move towards the direction adjustment component 8. When the two L-shaped thin plates 2 move directly above the two turntables 17 of the direction adjustment component 8, control the robotic arm 18 to close, and then control the second vacuum pump to close. At this time, the two L-shaped thin plates 2 fall onto the top surface of the two turntables 17 respectively.

[0057] S10. The rear vertical motor 16 of the control direction adjustment component 8 rotates clockwise, thereby driving the turntable 17 connected to it to rotate clockwise, and in turn driving the L-shaped thin plate 2 on it to rotate clockwise synchronously. When the L-shaped thin plate 2 has rotated 90°, the controller controls the rear vertical motor 16 to turn off. At the same time, the front vertical motor 16 of the control direction adjustment component 8 rotates counterclockwise, thereby driving the turntable 17 connected to it to rotate counterclockwise, and in turn driving the L-shaped thin plate 2 on it to rotate counterclockwise synchronously. When the L-shaped thin plate 2 has rotated 90°, the controller controls the front vertical motor 16 to turn off. At this time, the two L-shaped thin plates 2 are in the same direction, thus completing the adjustment of the direction of the two L-shaped thin plates 2. Figure 11 As shown;

[0058] S11. After adjusting the direction, control the movement of the robotic arm 18. The robotic arm 18 drives the movable rod 19 to move. The movable rod 19 drives the two suction heads B24 to move towards the two L-shaped thin plates 2 respectively. When the two suction heads B24 contact the top surfaces of the two L-shaped thin plates 2 respectively, control the robotic arm 18 to close, and then control the second vacuum pump to start. The two L-shaped thin plates 2 are adsorbed and fixed on the two suction heads B24 respectively.

[0059] S12. Control the movement of the robotic arm. The robotic arm 18 drives the movable rod 19 to move to the right. The movable rod 19 drives the two suction heads B24 to move towards the tape feeding direction of the tape feeding machine 9. When the two L-shaped thin plates 2 move to the top of the tape feeding machine, the controller robotic arm 18 is turned off, and then the second vacuum pump is turned off. The two L-shaped thin plates 2 fall into the tape feeding machine, thus finally completing the packaging of the first set of opposing parts on the tape into the tape feeding machine.

[0060] S13. The worker repeats steps S2 to S12 multiple times to finally package all the opposing parts on the strip into the tape tray. The L-shaped thin plates 2 inside the tape tray are arranged as follows: Figure 2 As shown.

[0061] As seen in steps S10-S12, this packaging machine uses the orientation adjustment component 8 to align the two L-shaped thin plates 2. Then, the two suction heads B24 of the robotic arm 18 automatically place the two oriented L-shaped thin plates 2 into the tape of the tape feeding machine. Therefore, compared to traditional workshop packaging methods, this packaging machine eliminates the need for workers to manually adjust the orientation of the L-shaped thin plates 2 or manually place them into the tape feeding machine. This significantly reduces worker workload and greatly improves the packaging efficiency of the parts.
