DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-7 This application is described in further detail.

[0034] The embodiment of the present application discloses a car door production line.

[0035] Example 1 Reference Figure 1 and Figure 2 The automobile door production line provided in the embodiment of the present application includes a front door installation motor module 1, the front door installation motor module 1 includes an installation workpiece base plate 2, a rope winding detection component 3 and a screw in place detection component 4, the installation workpiece base plate 2 is installed on a workbench, and a motor placement area and a door panel placement area are provided on the installation workpiece base plate 2, the motor placement area is located in the door panel placement area, the screw in place detection component 4 is arranged on the installation workpiece base plate 2 in the motor placement area, and the rope winding detection component 3 is arranged on the installation workpiece base plate 2 outside the door panel placement area.

[0036] The design of the motor placement area and the door panel placement area on the installation workpiece bottom plate 2 makes the installation position of the front door 10 more accurate. The setting of the screw position detection member 4 ensures the correct installation and detection of the screws, and the rope winding detection member 3 can make up for the inconvenience of detection during the rope winding installation, thereby avoiding rework or scrapping due to improper installation, and significantly reducing production costs. The automobile door production line realizes automated detection and installation during the installation process of the front door 10, reduces manual intervention, and improves production efficiency.

[0037] The rope winding detection member 3 is arranged outside the door panel placement area on the installation workpiece bottom plate 2, and is used to detect the rope winding condition of the front door 10. The rope winding detection member 3 can be a pressure sensor, which can detect whether the rope is wound in the correct order to ensure that the rope is wound correctly. In addition, a magnetic induction sensor can also be used as an alternative, which can also detect the state of the rope winding.

[0038] The screw in place detection member 4 is arranged on the installation workpiece bottom plate 2 in the motor placement area, and is used to detect whether the screw is screwed in place. The screw in place detection member 4 can be a proximity switch, which can detect the screwing state of the screw. When the screw is fully screwed in, the proximity switch will send a signal. In addition, a photoelectric sensor or a pressure sensor can also be used as an alternative, which can also detect the screwing state of the screw.

[0039] Reference Figure 1 and Figure 2A pressing piece 5 is provided on the installation workpiece bottom plate 2. The pressing piece 5 is arranged outside the door panel placement area of ​​the installation workpiece bottom plate 2. The pressing piece 5 includes a cylinder and a pressing plate. The cylinder is installed on the installation workpiece bottom plate 2 and is connected to the compressed air source through an air pipe to generate sufficient thrust. The pressing plate is rotatably mounted on the piston rod of the cylinder and can be made of metal material with a smooth surface that is not easy to scratch the front door 10. When the cylinder is working, the pressing plate will move downward to firmly press the front door 10 on the installation workpiece bottom plate 2 to ensure the stability of the front door 10 during the installation process.

[0040] Reference Figure 1 and Figure 2 The screw-in-place detection member 4 and the pressing member 5 are both electrically connected to the controller, which may be a PLC controller. When the screw-in-place detection member 4 detects that the screw is screwed into place, it sends a position signal to the controller. The controller receives the position signal and controls the pressing member 5 to contact and press the front door 10.

[0041] The implementation principle of an automobile door production line in Example 1 of the present application is as follows: an operator places the motor and the front door 10 to be installed of the motor on the installation workpiece base plate 2 in sequence, and at this time the rope winding detection component 3 can detect whether the rope is wound in the correct order; at the same time, the operator pre-places the screws in the screw holes of the front door 10, and the operator controls the automatic screw gun to screw the screws pre-placed in the screw holes of the front door 10 into the screw holes, and when the screw-in-place detection component 4 detects that the screws have been screwed into place, a position-in-place signal is sent to the controller, and the controller receives the position-in-place signal and controls the pressing component 5 to release the pressure on the front door 10, and the operator removes the front door 10 after the motor is installed, and places the motor and the front door 10 to be installed of the motor on the installation workpiece base plate 2 in sequence, and repeats the above operations. The design of the motor placement area and the door panel placement area on the installation workpiece base plate 2 makes the installation position of the front door 10 more accurate. The setting of the screw position detection part 4 ensures the correct installation and detection of the screws, and the rope winding detection part 3 can make up for the inconvenience of detection during the rope winding installation, thereby avoiding rework or scrapping due to improper installation, and significantly reducing production costs. The automobile door production line realizes automated detection and installation during the installation process of the front door 10, reduces manual intervention, and improves production efficiency Example 2 The difference between this embodiment and embodiment 1 is that: Figure 3 A screw feeding assembly 6 is provided on one side of the workpiece installation base plate 2, and a linkage synchronization assembly 7 is provided between the screw feeding assembly 6 and the workpiece installation base plate 2. The front door 10 is placed on the workpiece installation base plate 2, and the linkage synchronization assembly 7 controls the screw feeding assembly 6 to move toward the direction close to the front door 10 to feed the screws into the screw holes of the front door 10.

[0042] The linkage synchronization component 7 between the screw feeding component 6 and the installation workpiece bottom plate 2 can automatically control the screw feeding component 6 to move toward the front door 10 when the front door 10 is placed on the installation workpiece bottom plate 2, so as to ensure that the screws are accurately fed into the screw holes of the front door 10; and when the front door 10 is installed and taken away, the linkage synchronization component 7 can move the entire screw feeding component 6 upward to reduce the collision with the front door 10. This design reduces the manual operation of taking and placing screws, improves the accuracy and efficiency of screw installation, and further reduces production costs.

[0043] Reference Figure 3 and Figure 4 The screw feeding assembly 6 includes a storage frame 61 and a feeding frame 62. The storage frame 61 is installed on a workbench and is used to store a large number of screws. A vibration plate is provided at the bottom of the storage frame 61, which can vibrate the screws in the storage frame 61 into the feeding frame 62.

[0044] The side of the material storage frame 61 close to the workpiece mounting base plate 2 is flexibly connected to the loading frame 62 . In this embodiment, the flexible connection uses elastic plastic with elasticity to connect the screw outlet of the material storage frame 61 and the screw inlet of the loading frame 62 .

[0045] A plurality of partitions 621 are integrally formed or clamped in the feeding frame 62, and the plurality of partitions 621 are used to divide the feeding frame 62 into a plurality of areas, and a feeding channel 63 is fixedly installed in each area of ​​the feeding frame 62. In this embodiment, the feeding frame 62 is divided into three areas by two partitions 621, and the three areas of the feeding frame 62 correspond to three feeding channels 63. The plurality of feeding channels 63 are connected to one end of the feeding frame 62 away from the material storage frame 61, and one end of the plurality of feeding channels 63 away from the feeding frame 62 can be moved to the top of the screw hole of the front door 10 through the linkage synchronization component 7, and at this time, the feeding frame 62 and the feeding channel 63 move synchronously.

[0046] Reference Figure 3 and Figure 4The feeding frame 62 is provided with a screw guide 8 between each partition 621. The screw guide 8 guides the screw so that it can move along the feeding channel 63 to the screw hole of the front door 10. The screw guide 8 includes a plurality of guide bar groups 81. The guide bar groups 81 are pre-set with guide long holes 811. The guide long holes 811 are arranged along the length direction of the guide bar groups. The width of the guide long holes 811 is smaller than the head diameter of the screw and larger than the thread section diameter of the screw. One end of the guide bar group 81 in the length direction is connected to the inner wall of the feeding frame 62, and the other end has a lowering gap with the feeding frame 62. The length direction of each guide bar group 81 is perpendicular to the length direction of the feeding channel 63. A plurality of guide bar groups 81 are sequentially arranged in the feeding frame 62 along the direction close to the feeding channel 63. The lowering gaps formed by adjacent guide bar groups 81 and the feeding frame 62 are respectively located on both sides of the feeding frame 62, so that multiple lowering gaps are arranged in an alternating manner.

[0047] In order to ensure that the loading frame 62 can smoothly load the screws into the loading channel 63, each guide strip group 81 is tilted downward in the direction of the downward gap formed by the guide strip group 81 and the loading frame 62, so that the screws can move on the guide strip group 81 in the direction of the downward gap under the action of gravity.

[0048] The screw is vibrated by the vibration disk through the storage frame 61 and enters the loading frame 62. At this time, the threaded section of the screw is inserted into the long guide hole 811, and the head of the screw is placed on the guide strip group 81. Under the action of gravity, the screw moves in the direction of the release gap, and slides into the adjacent guide strip group 81 at the lowering gap, and finally slides from the lowering gap of the loading frame 62 close to the loading channel 63 to the loading channel 63.

[0049] Reference Figure 4 and Figure 5 The feeding channel 63 includes a channel body 631. The channel body 631 and the feeding frame 62 are both inclined, and the inclination direction is downward from the feeding frame 62 to the channel body 631, that is, the height of one end of the channel body 631 away from the feeding frame 62 is lower than the height of the other end.

[0050] A turning long hole 632 and a positioning circular hole 633 are provided at one end of the channel body 631 away from the loading frame 62 and on the bottom wall of the channel body 631. The turning long hole 632 and the positioning circular hole 633 are connected. The turning long hole 632 is located between the positioning circular hole 633 and the loading frame 62. The width of the turning long hole 632 is smaller than the diameter of the screw head and larger than the diameter of the screw thread section. The diameter of the positioning circular hole 633 is equal to the diameter of the screw head.

[0051] The screw slides into the channel body 631 through the loading frame 62 and slides along the length direction of the channel body 631. When the screw slides to the turning long hole 632, the screw rotates downward at the turning long hole 632 under the action of gravity. At this time, the threaded section of the screw passes through the turning long hole 632, and finally forms a screw head facing upward and rests on the channel body 631. Finally, under the action of gravity, it moves from the turning long hole 632 to the positioning circular hole 633 along the length direction of the channel body 631. At this time, the end of the screw threaded section is just located in the screw hole of the front door 10, and the inner wall of the positioning circular hole 633 can limit the screw to prevent the screw from tilting.

[0052] Under the action of gravity, the sliding of each screw is continuous. In order to stop the screw from sliding when the operator is replacing the front door 10, a limit member 9 is provided on the channel body 631 between the turning long hole 632 and the positioning circular hole 633 and on the end of the turning long hole 632 away from the positioning circular hole 633. The limit member 9 can limit the movement of the screw toward the positioning circular hole 633. The limit member 9 is connected to the linkage synchronization component 7 to control whether the channel body 631 is conducted at the limit member 9.

[0053] The limiting member 9 includes a limiting disc 91, a limiting torsion spring and a limiting rope 92. The limiting disc 91 is rotatably connected to the edge of the channel body 631. The channel body 631 is provided with a limiting hole 634 for the limiting disc 91 to pass through. The length of the limiting hole 634 is equal to the radius of the limiting disc 91. The limiting torsion spring is installed at the rotating shaft connecting the limiting disc 91 and the channel body 631. One end of the limiting rope 92 is connected to the limiting disc 91 and the other end is linked to the linkage synchronization component 7. The limiting discs 91 of the two limiting members 9 on the same channel body 631 are connected through a shaft to achieve synchronous rotation. A passing notch 911 is provided on the limiting disc 91. The passing notch 911 is a quarter virtual circle of the limiting disc 91. When the passing notch 911 is located in the channel body 631, the screw can pass smoothly. There is a gap between the round edge of the limiting disc 91 and the threaded section of the screw, and the limiting disc 91 can contact the screw head.

[0054] In order to prevent multiple screws from sliding continuously to the positioning circular hole 633, the channel gaps of the two limiting discs 91 are staggered and connected to the channel body 631; the length of each turning long hole 632 is customized according to the center of gravity position under different screw specifications.

A linkage hole 21 is provided on the workpiece installation base plate 2, and the first linkage rod 71 is inserted into the linkage hole 21. An elastic member 22 connected to the linkage hole 21 is embedded in the bottom of the linkage hole 21. In this embodiment, the elastic member 22 is a spring, one end of which is fixedly connected to the first linkage rod 71 and the other end is connected to the workpiece installation base plate 2; the second linkage rod 72 is fixedly connected to the bottom of the channel body 631, and one end of the second linkage rod 72 away from the channel body 631 is fixedly connected to the connecting rod 73, and one end of the connecting rod 73 away from the second linkage rod 72 passes through the side wall of the workpiece installation base plate 2 and is fixedly connected to the first linkage rod 71. The middle part of the connecting rod 73 slides on the installation workpiece base plate 2. The installation workpiece base plate 2 is provided with a connecting hole 23 that communicates with the linkage hole 21. The connecting rod 73 is inserted into the connecting hole 23. The bottom of the connecting hole 23 is also embedded with an elastic member 22 connected to the connecting rod 73. In this embodiment, the elastic member 22 is a spring, one end of the spring is fixedly connected to the connecting rod 73 and the other end is connected to the installation workpiece base plate 2; the first linkage rod 71 can be pressed by the front door 10, and the first linkage rod 71 and the second linkage rod 72 rise or fall synchronously through the connecting rod 73.

[0056] The limiting rope 92 of the limiting disc 91 near the loading frame 62 passes through the connecting rod 73 and is connected to the side wall of the workpiece installation base plate 2. The limiting disc 91 near the positioning circular hole 633 is connected to the limiting disc 91 near the loading frame 62 through the shaft rod.

At this time, the limiting rope 92 is pressed downward, the limiting disc 91 rotates, and the through notch 911 located at the positioning circular hole 633 is gradually connected with the channel body 631, and the through notch 911 located at the turning long hole 632 is gradually misaligned with the channel of the channel body 631. At this time, the only screw located at the steering long hole 632 is turned at the steering long hole 632 due to the action of gravity, and the threaded section of the screw passes through the steering long hole 632. The head of the screw is placed on the channel body 631, and finally moves from the steering long hole 632 to the positioning circular hole 633 along the length direction of the channel body 631 under the action of gravity. At this time, the end of the threaded section of the screw is just located at the hole mouth of the threaded hole of the front door 10. At this time, the inner wall of the positioning circular hole 633 restricts the screw from being excessively skewed, and the operator uses an automatic screw gun to position the screw. The screws in the positioning circular holes 633 are screwed into the screw holes of the front door 10; when the three screw holes are screwed, the pressing member 5 releases the pressing on the front door 10, and the front door 10 after the motor is installed is removed by the operator. At this time, under the action of the elastic member 22, the connecting rod 73 drives the first linkage rod 71 and the second linkage rod 72 to rise, and the second linkage rod 72 drives the channel body 631 and the loading frame 62 to rise. At this time, the end of the loading frame 62 close to the storage frame 61 contacts the storage frame 61, and at the same time, the vibration plate under the storage frame 61 starts The screw in the material storage frame 61 is moved to allow the screw in the material loading frame 62 to enter the material loading frame 62; at this time, due to the rise of the connecting rod 73, the two limiting discs 91 gradually rotate, and the through notch 911 located at the positioning circular hole 633 gradually misaligns with the channel body 631 through the notch 911, and the through notch 911 located at the steering long hole 632 gradually communicates with the channel of the channel body 631. At this time, the screw moves to the steering long hole 632 under the action of gravity, and is blocked by the limiting disc 91 located at the positioning circular hole 633 until the front of the motor to be installed The door 10 is placed on the workpiece installation base plate 2, and the above-mentioned actions are repeated; at the same time, when the loading frame 62 and the channel body 631 are reset, the loading frame 62 contacts the end wall of the storage frame 61, and the screws in the storage frame 61 slide smoothly into the loading frame 62, and the storage frame 61 contacts the loading frame 62, and the loading frame 62 and the channel body 631 are also driven by the vibration disk to vibrate, thereby accelerating the movement of the screws; through the structure of automatic screw loading, the occurrence of manual screw picking and focusing of the screw holes is reduced, thereby further improving work efficiency.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
