Description

Technical Field

[0001] The present invention relates to the technical field of automobile production, and more specifically, to a double-station automobile door panel assembly production line. Background Art

[0002] At present, the existing car door processing is all clamped by a robot arm, and then the processing device processes the car door. After processing, the car door is transferred to the next process through the robot arm, and then the robot arm picks up the next car door to be processed. Although a single robot arm can be used to complete all processing steps, the use of one thing for one purpose will greatly reduce production efficiency. For example, when the robot arm carries the car door to move, the processing device is in a standby and non-operating state, which will cause the equipment processing frequency to be low and the production efficiency to be low. Therefore, how to improve production efficiency and increase the equipment processing frequency is the technical problem to be solved by the present invention. Summary of the invention

DETAILED DESCRIPTION

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0043] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0044] like Figure 1-Figure 18 As shown, the present invention provides a double-station automobile door panel assembly production line, comprising: a first placement device 100, for placing a workpiece 800 to be processed;

[0045] The first robot arm 200 is used for processing the workpiece 800 and clamping and transferring the workpiece 800 through the transfer device 700;

[0046] The processing device 300 is used to process the workpiece 800 transferred by the first robot arm 200;

[0047] The double-station device 400 is used to place and fix the workpiece 800 transferred by the first robot arm 200;

[0048] The second robot arm 500 is used for processing the workpiece 800;

[0049] The second storage device 600 is used to place and fix the transfer device 700.

[0050] The working principle and beneficial effects of the above technical solution are as follows: Figure 1-7 The complete production process of the present invention is shown, and the specific steps are as follows:

[0051] S1: placing the workpiece to be processed on the first placement device 100;

[0052] S2: The first robot arm 200 equipped with the transfer device 700 removes the workpiece from the first placement device 100 through the transfer device 700;

[0053] S3: The first robot arm 200 transports the workpiece to the processing device 300 through the transfer device 700 for processing. During this period, the first robot arm 200 can adjust the position of the workpiece in real time to facilitate the processing of the workpiece by the processing device 300;

[0054] S4: After the processing device 300 completes the processing, the first robot arm 200 places the workpiece on the workstation A of the double-workstation device 400 through the transfer device 700;

[0055] S5: The station A of the double-station device 400 where the workpiece is placed starts to operate (station B does not operate), positions the workpiece, and clamps and fixes it on station A;

[0056] S6: The transfer device 700 on the first robot arm 200 releases the clamping of the workpiece;

[0057] S7: The first robot arm 200 delivers the transfer device 700 to the second placement device 600. After the second placement device 600 positions, clamps and fixes the transfer device 700, the first robot arm 200 is separated from the transfer device 700. The separated first robot arm 200 moves to the workpiece to process the workpiece.

[0058] S7': After the first robot arm 200 and the transfer device 700 are separated from the workpiece, the second robot arm 500 processes the workpiece;

[0059] S8: The first robot arm 200 of the separation transfer device 700 processes the workpiece together with the second robot arm 500. When the processing is nearly finished, the first robot arm 200 leaves the workpiece and moves to the second placement device 600, and connects with the transfer device 700 on the second placement device 600, so that the first robot arm 200 resumes control over the transfer device 700;

[0060] S9: The first robot arm 200 moves to the first placement device 100 through the transfer device 700 to start processing the next workpiece. After the second robot arm 500 finishes processing the workpiece, the double-station device 400 rotates to rotate the idle station B to the position to be processed. Before the double-station device 400 rotates again, the previously processed workpiece can be removed from station A.

[0061] Through the design of the above structure, the first robot arm 200 is used to transfer and process the workpiece, while the second robot arm 500 only processes the workpiece on the dual-station device 400. After the workpiece processing enters the final stage, the first robot arm 200 no longer processes, but starts the processing flow of the next workpiece. After the second robot arm 500 completes the processing, there is no need to rely on the first robot arm 200 to remove the workpiece, but directly replace the idle workstation for the placement of the next workpiece. The processed workpiece only needs to be removed before the dual-station device 400 rotates again, thereby greatly reducing production time and improving production efficiency. The rotation mode of the dual-station device 400 can effectively separate the processed workpiece from the processing atmosphere, so that no matter whether it is manual or mechanical retrieval, the other equipment will not interfere with the retrieval.

[0062] The double-station device 400 is composed of a welding frame 3 connected to a platform 1 through a rotating system 2, and two positioning and clamping modules 4 symmetrically arranged on the welding frame 3. The rotating system 2 is used to control the rotation of the welding frame 3. The rotating system 2 can be a combination of a commercially available motor and a supporting roller, such as Figure 8 , 9 As shown in , it can also be any existing technology that can rotate the welding frame 3. Usually, the two positioning and clamping modules 4 clamp the workpiece 800 alternately. It should be noted that the alternating clamping mentioned here does not mean that there cannot be two workpieces 800 on the two positioning and clamping modules 4 at the same time, but as long as it does not affect the subsequent clamping and fixation of the workpiece 800. The welding frame 3 is composed of a connecting plate 31 movably connected to the rotating system 2, a support frame 32 arranged on the connecting plate 31, and two symmetrically arranged inclined connecting frames 33. The two positioning and clamping modules 4 are respectively arranged on the two connecting frames 33. The connecting plate 31 is connected to the rotating system 2 so that the rotating system 2 can drive the connecting plate 31 to rotate, and then the support frame 32 and the connecting frame 33 thereon rotate. In order to optimize the volume of the double-station device 400 and reduce the floor space, the connecting frame 33 is usually arranged at an angle and assembled with the connecting plate 31 as shown in the figure. Fig.10The triangle shown in the figure makes the workpiece 800 clamped by the positioning and clamping module 4 tilted instead of lying flat. The positioning and clamping module 4 is composed of a carrier 41 connected to the welding frame 3, a mold 42 arranged on the carrier 41, a plurality of clamping members 43, and at least two positioning members 44. The shape of the mold 42 is adapted to the shape of the workpiece 800, as shown in FIG. Fig.12 As shown, at least two trigger devices 5 are arranged on the mold 42. When the workpiece 800 contacts the trigger device 5, the positioning member 44 and the clamping member 43 position, clamp and fix the workpiece 800. The mold 42 is used to support the workpiece 800. The clamping member 43 and the positioning member 44 are cylinder-driven, commercially available products or existing technologies composed of a pressure block, a pressure arm and other structures, such as Fig.13 As shown, as long as the clamping member 43 and the positioning member 44 do not affect the placement of the workpiece before the workpiece 800 is clamped, when the workpiece 800 is clamped, the positioning pin on the positioning member 44 can be inserted and positioned with the positioning hole on the workpiece 800, and the clamping member 43 can clamp the workpiece 800. Multiple clamping members 43 can be provided according to the shape of the workpiece 800. The trigger device 5 is composed of a first connecting member 51 connected to the tire mold 42, a trigger member 52 for abutting against the workpiece 800, and a detection device 53 connected to the trigger member 52, as shown in FIG. Fig.12 As shown, a first embodiment of the trigger device 5 is shown, that is, the trigger member 52 is fixed to the tire mold 42 by the first connecting member 51. When the workpiece 800 abuts against the trigger member 52, the detection device 53 detects that the workpiece 800 abuts against the tire mold 42, and transmits the instruction to the clamping member 43 and the positioning member 44, thereby completing the clamping of the workpiece 800.

[0063] In the previous embodiment, we disclosed the first implementation of the trigger device 5, which is a fixed type, that is, the trigger member 52 does not move with the contact of the workpiece 800, so in the first implementation, the trigger member 52 needs to be located at the extreme position, that is, when the workpiece 800 is attached to the tire mold 42, the trigger member 52 just contacts the workpiece 800. The advantage of this implementation is that the structure of the trigger device 5 is simple, but the requirements for installation accuracy are high, because usually there are multiple trigger devices 5, as long as there is one that does not contact the workpiece 800, the positioning and clamping module 4 cannot clamp the workpiece. For this reason, the force of the workpiece 800 abutting on the tire mold 42 cannot be measured, and it is necessary to manually debug the moving position of the first robot arm 200 to drive the workpiece 800 in the early stage to avoid crushing the tire mold 42 and the workpiece 800. In order to optimize the installation steps of the equipment and reduce the requirements for installation accuracy, we provide another embodiment of the trigger device 5. In the second embodiment, the trigger member 52 is composed of a first sleeve 61 connected to the first connecting member 51, a first abutment member 62 arranged in the first sleeve 61, a conversion member 63 movably connected to the first abutment member 62, and a first reset member 64 sleeved on the first abutment member 62. Fig.14As shown, the opening of the first sleeve 61 is located at the bottom, the top of the first abutment member 62 passes through the top of the first sleeve 61 and is movably connected to the first sleeve 61, and the conversion member 63 is movably connected to the inner wall of the first sleeve 61 through the rotating member 68. The rotating member 68 can be a torsion spring or other commercially available products or existing technology, as long as the conversion member 63 can be fixed on the first sleeve 61 and can provide torque to reset it when it rotates. If the rotating member 68 adopts a bearing or other commercially available product or structure that simply rotates it, an elastic member that can provide torque to it and help it rotate and reset should be added to the conversion member 63. The detection device 53 is set at the bottom of the conversion member 63 and connected to the first connecting member 51, so as to prevent the detection device 53 from being displaced. In this embodiment, an angle detection device can be used as the detection device 53, because the conversion member 63 can convert the vertical movement of the first abutment member 62 into its own rotation, so it only needs to detect the rotation angle of the conversion member 63. The bottom of the first abutment member 62 is provided with a sliding column 65 with an inclined bottom surface and a first slot. The outer wall of the sliding column 65 is adapted to the inner wall of the first sleeve 61. The first slot penetrates the sliding column 65 and extends to the inside of the first abutment member 62. The bottom surface of the sliding column 65 is divided into a high point and a low point. The distance between the low point and the rotating member 68 is smaller than the distance between the high point and the rotating member 68. The conversion member 63 is cylindrical and is movably connected to the first abutment member 62 through the first slot. The side wall of the conversion member 63 is provided with a roller 67 through a connecting shaft 66. The roller 67 abuts against the bottom surface of the sliding column 65 and can roll along the bottom surface of the sliding column 65. One end of the first reset member 64 abuts against the inner top surface of the first sleeve 61, and the other end abuts against the top surface of the sliding column 65. The first abutment member 62 and the conversion member 63 are located on the same central axis, and the central axis of the conversion member 63 is parallel to the central axis of the first sleeve 61, thereby making the first slot and the sliding column 65 in an eccentric state, so that the sliding column 65 can prevent rotation. Similarly, a card groove or other card connection structure can be provided on the side wall of the sliding column 65, so that the sliding column 65 can only slide in the vertical direction and cannot rotate. In this embodiment, the top surface of the first abutment member 62 is higher than the top surface of the tire mold 42. When the workpiece 800 does not abut on the first abutment member 62, the roller 67 is located at the low point of the sliding column 65 under the action of the first reset member 64. When the workpiece 800 contacts the first abutment member 62, it will drive the first abutment member 62 to move downward, thereby causing the sliding column 65 to move downward. Because the conversion member 63 can only rotate on its own and will not be displaced in the vertical and horizontal directions, under the action of the sliding column 65, the roller 67 will roll along the bottom surface of the sliding column 65 from the low point to the high point, thereby driving the conversion member 63 to rotate through the connecting shaft 66. Fig.15As shown in A to B, the rotation angle of the conversion member 63 is monitored by the detection device 53. When the conversion member 63 rotates to the specified angle, the workpiece 800 is attached to the surface of the tire mold 42, and the positioning and clamping module 4 starts to clamp the workpiece 800. After the workpiece 800 is taken away, under the action of the first reset member 64, the sliding column 65 and the first abutment member 62 move up and reset, and the conversion member 63 is reset under the action of the rotating member 68. Therefore, when installing the trigger device 5, the rotation angle of the conversion member 63 when the workpiece 800 is attached to the tire mold 42 can be recorded, and then the moving distance of the workpiece 800 driven by the first mechanical arm 200 can be adjusted to avoid excessive force on the tire mold 42, which will damage the workpiece 800 and the tire mold 42.

[0064] In the second embodiment, the transport distance of the first robot arm 200 is optimized by digitizing the positional relationship between the workpiece 800 and the tire mold 42 after being fitted. As a result, when the workpiece 800 is fitted with the tire mold 42, the pressure from the first robot arm 200 is minimal. Compared with the first embodiment, in addition to optimizing the installation and debugging, the risk of the workpiece 800 and the tire mold 42 being crushed is also greatly reduced. In order to further optimize the trigger device 5, we provide a third embodiment, in which the trigger member 52 is composed of two second sleeves 72 and a third sleeve 73 with bottom openings symmetrically arranged on the first connecting member 51, a second connecting member 75 movably connected to the first connecting member 51 through a rotating shaft 74, and a second abutment member 76 movably connected to the second connecting member 75. The second connecting member 75 can rotate with the rotating shaft 74 as the rotating axis. The detection device 53 is connected to the rotating shaft 74 to monitor and record the rotation angle of the rotating shaft 74. The first connecting member 51 The top surface is provided with three open grooves, namely the first groove 711, the second groove 712, and the third groove 713. The second groove 712 and the third groove 713 are both cylindrical grooves adapted to the second sleeve 72 and the third sleeve 73. The second connecting member 75 is located in the first groove 711, and the second sleeve 72 is located in the second groove 712, and abuts against the inner bottom of the second groove 712 through the second reset member 721 in the second sleeve 72. In order to prevent the entry of impurities, a friction pair can be provided on the outer wall of the second sleeve 72 for sealing. The second reset member 721 can be as follows Fig.17 The double-layer spring shown in the figure, the third sleeve 73 is located in the third groove 713, and abuts against the inner bottom of the third groove 713 through the third reset member 731 in the third sleeve 73. In order to prevent the entry of impurities, a friction pair can be set on the outer wall of the third sleeve 73 for sealing. The third reset member 731 can be as follows Fig.17 It should be noted that when the workpiece 800 is not in contact with the second abutment member 76, the second sleeve 72 is higher than the third sleeve 73. Fig.17As shown, the second abutment member 76 is thereby in an inclined state, and one end of the second abutment member 76 close to the second sleeve 72 should protrude from the surface of the tire mold 42 , and the top of the second sleeve 72 and the top of the third sleeve 73 are both movably connected to the second abutment member 76 . A second slot is provided on the top of the second connecting member 75, and the second abutment member 76 is a T-shaped structure. The bottom of the second abutment member 76 is located in the second slot and is movably connected to the second slot. A third slot is provided on the top surface of the second abutment member 76, and a screw 77 is provided in the third slot. The threaded section of the screw 77 passes through the inner bottom surface of the third slot and the inner bottom surface of the second slot, and is threadedly connected to the rotating shaft 74 of the second connecting member 75, so that under the drive of the screw 77, the second abutment member 76 can rotate with the rotating shaft 74 as the rotating axis, and the second abutment member 76 can translate along the screw 77. An inclined first sliding groove is provided on the second sleeve 72, and a second sliding groove symmetrical to the first sliding groove is provided on the third sleeve 73. A first sliding rod 761 and a second sliding rod 762 are provided on the second abutment member 76. The first sliding rod 761 passes through the first sliding groove, and the second sliding rod 762 passes through the second sliding groove. The second abutment member 76 realizes synchronous movement with the two sleeves through the two sliding rods. When the workpiece 800 contacts the second abutment member 76, the workpiece 800 first abuts against the end of the second abutment member 76 close to the second sleeve 72 (i.e., the end protruding from the surface of the tire mold 42), and then as the workpiece 800 moves toward the tire mold 42, the second abutment member 76 is driven to rotate with the rotation axis 74 as the rotation axis until it is parallel to the surface of the tire mold 42, and the detection device 53 transmits a signal to the positioning and clamping module 4, and the positioning and clamping module 4 clamps the workpiece 800. During the clamping process, the workpiece 800 gradually fits the surface of the tire mold 42, thereby driving the second abutment member 76 to move in the direction of the second connecting member 75, as shown in FIG. Fig.18 As shown in Figures C to E, at this time, the second reset member 721 is in a compressed stress state, and the third reset member 731 is in a stretched stress state. After the workpiece 800 leaves, the second abutting member 76 is reset under the action of the second reset member 721 and the third reset member 731. In this embodiment, a translation distance is reserved for the second abutting member 76, so that when the workpiece 800 moves toward the double-station device 400, the moving speed can be increased. The second abutting member 76 adopts a large plane design, such as Fig.16 As shown, the contact area with the workpiece 800 can be increased, and the rotation of the second abutment member 76 can directly and quickly respond to the detection device 53. Therefore, when the workpiece 800 touches the second abutment member 76, the feed speed of the workpiece 800 can be reduced in time to avoid the workpiece 800 colliding with the positioning clamping module 4 due to the increase in the feed speed.
