Description

Technical Field

[0001] The present invention relates to the technical field of vehicle body processing, in particular to a vehicle body bolt feeding device. Background Art

[0002] During the vehicle body processing process, the studs need to be threaded and fixed at the body joints. At this time, the loading mechanism needs to supply materials to the nail gun, which picks up the bolts from the loading mechanism and transfers them to the body to complete the threaded fixation on the body. Currently, the loading and long-distance transportation of bolts are mostly achieved by arranging them on a vibration plate, conveying them on a conveyor belt, and adding a bolt suction and handling mechanism (i.e., the nail gun). If the nail gun fails to pick up the material or a bolt that cannot be picked up appears on the conveyor belt, the entire process will be disrupted, resulting in problems such as the nail gun picking up nothing or the conveyor belt being blocked, which greatly affects the efficiency of the automated bolt supply and further affects the efficiency of the overall body production. It may also cause threaded fixation failure, affecting the product quality of the body and causing economic losses. Summary of the Invention

[0037] like Figures 1 to 3As shown, a vehicle body bolt loading device according to a preferred embodiment of the present invention comprises a vibrating plate 1 and a conveyor belt 2, wherein the conveyor belt 2 is provided with a positioning mechanism 3 which can move along the conveying direction of the conveyor belt 2; the vibrating plate 1 is used to sequentially supply bolts to the positioning mechanism 3 in the conveyor belt 2, and the conveyor belt 2 is arranged on the outlet side of the vibrating plate 1, and the end of the conveyor belt 2 close to the vibrating plate 1 is set as a loading station 21, and the loading station 21 is used for the vibrating plate 1 to transport the bolts to the positioning mechanism 3, and the end of the conveyor belt 2 away from the vibrating plate 1 is set as a picking station 22, and the picking station 22 is used to take out the bolts carried by the positioning mechanism 3 for vehicle body processing; further, the positioning mechanism 3 is slidably connected to the conveyor belt 2 to move back and forth between the loading station 21 and the picking station 22, and a plurality of bolt fixing positions 31 are provided on the positioning mechanism 3, and the plurality of bolt fixing positions 31 are arranged at intervals, and a bolt can be fixed in each bolt fixing position 31.

[0038] A fixing mechanism 4 and a picking mechanism 5 are provided at the picking station 22. The fixing mechanism 4 is provided on one side of the picking station 22 of the conveyor belt 2. The fixing mechanism 4 includes a movable abutment arm 41. The abutment arm 41 extends to the fixing mechanism 4 after the positioning mechanism 3 reaches the picking station 22 to fix the bolts in the bolt fixing position 31; the picking mechanism 5 includes a picking gun 51 and a first detection device 52. The picking gun 51 is provided above the picking station 22 and is used to take the bolts out of the positioning mechanism 3 and send them to the car body processing process; the first detection device 52 includes a first detection device 52 provided on one side of the picking station 22, the first detection device 52 is aligned with the picking gun 51, and the first detection device 52 is used to detect the number and posture of the bolts in the picking gun 51, and thereby determine whether the picking gun 51 has successfully picked up the bolts.

[0039] A blowing mechanism 6 is also provided at the loading station 21. The blowing mechanism 6 is provided on one side of the loading station 21. After the positioning mechanism 3 takes the material, it carries the bolts that failed to be taken to the blowing mechanism 6. The blowing mechanism 6 will blow off the remaining bolts and collect them to complete the unloading of the excess bolts.

[0040] The present application further includes a controller, which is used to control the action of each component and is also electrically connected to the first detection device 52. Specifically, the controller includes a single chip microcomputer and a PLC.

[0041] During operation, the vibration plate 1 arranges the bolts and sends them to the bolt fixing position 31 on the positioning mechanism 3. After the positioning mechanism 3 is filled with bolts on the loading station 21, it is sent to the picking station 22 by the conveyor belt 2. After arriving at the picking station 22, the abutment arm 41 of the fixing mechanism 4 moves toward the positioning mechanism 3 to fix the bolts. The picking gun 51 moves down to take out the bolts from the bolt fixing position 31 and then moves up. The first detection device 52 detects the picking gun 51. If the bolts on the picking gun 51 are well fixed and the number is correct, the picking gun 51 directly takes the bolts. The bolts are sent to the next car body processing process, and the positioning mechanism 3 returns to the vibration disk 1 to reload; if the number of bolts on the feeding gun 51 is insufficient or the bolt position is inaccurate, a signal is sent to the control to notify the feeding gun 51 to reload. After the feeding gun 51 unloads the old material, it re-absorbs the new bolts in the remaining bolt fixing position 31 of the positioning mechanism 3, and is inspected again by the first detection device 52. After the feeding is completed, the positioning mechanism 3 first returns to the blowing mechanism 6 to blow off the bolts that cannot be taken out, and then reaches the vibration disk 1 to reload and enter the next cycle. The automatic bolt feeding device of the present application has a detection mechanism, and the feeding gun 51 is detected after the feeding gun 51 takes the material to prevent the feeding gun 51 from failing to take the material or the appearance of the bolts that cannot be taken on the conveyor belt 2, which will cause the entire process to be disordered, thereby ensuring the efficiency of the automatic bolt supply, and further ensuring the efficiency of the overall car body production, improving the product quality of the car body, and ensuring the economic benefits of the product.

[0042] In some embodiments of the present invention, a second detection device 11 is further included. The second detection device 11 is arranged above the material picking station 22 to detect whether the bolt loading on the positioning mechanism 3 is successful. The second detection device 11 is aligned with the positioning mechanism 3 at the outlet of the vibration plate 1, and focuses on detecting the bolt fixing position 31 on the positioning mechanism 3; the second detection device 11 is also electrically connected to the controller. If there is no bolt on the bolt fixing position 31 or the bolt posture is incorrect, the controller sends a signal to adjust the positioning mechanism 3 to reload the material, thereby ensuring the quality of the bolt loading of the positioning mechanism 3, facilitating the subsequent material picking by the material picking gun 51, improving the success rate of the material picking by the material picking gun 51, and ensuring the efficiency of the car body processing.

[0043] In some embodiments of the present invention, at least four bolt fixing positions 31 are provided on the positioning mechanism 3. When the number of bolt fixing positions 31 is greater than four, the number of bolt fixing positions 31 is set to an even number. The material picking gun 51 picks up two bolts at a time. When the material picking fails, the material picking gun 51 can pick up the material at least once after unloading. The setting of multiple bolt fixing positions 31 provides the material picking gun 51 with sufficient bolt supply for multiple material picking. There is no need to return to the vibration plate 1 for reloading after the material picking fails, thereby improving the material picking efficiency of the material picking gun 51.

[0044] In some embodiments of the present invention, the positioning mechanism 3 includes a fixing block 32, which is used to fix the bolts; a plurality of first fixing plates 33 are arranged at intervals on the fixing block 32, and the plurality of first fixing plates 33 are arranged parallel to each other; a second fixing plate 34 is connected between the first fixing plates 33, and the two ends of the second fixing plate 34 are fixed on two adjacent first fixing plates 33; the space enclosed by the two first fixing plates 33 and the second fixing plates 34 is rectangular, and a bolt fixing position 31 is formed in this space, and one side of the bolt fixing position 31 has an opening to facilitate the abutting arm 41 to extend into the bolt fixing position 31 to fix the bolt, thereby facilitating the material taking of the material taking gun 51.

[0045] In some embodiments of the present invention, the fixing mechanism 4 includes a third detection device and a drive device 42. The third detection device is electrically connected to the controller. The third detection device is directed toward the positioning mechanism 3 that has reached the material retrieving station 22 to detect whether the positioning mechanism 3 has reached the material retrieving station 22. If it is detected that the positioning mechanism 3 has reached the corresponding position, a signal is sent to the controller, and the controller activates the drive device 42. The drive device 42 drives the abutment arm 41 to extend into the conveyor belt 2 to fix the bolts on the positioning mechanism 3. The provision of the third detection device enables the abutment arm 41 to work accurately, ensuring that the bolts on the positioning mechanism 3 are well fixed. Furthermore, the drive device 42 includes a cylinder, etc.

[0046] In some embodiments of the present invention, the side plate of the conveyor belt 2 has two positioning holes at the material picking station 22, the distance between the positioning holes matches the distance between the two bolt fixing positions 31, and the abutment arm 41 moves to the bolt fixing position 31 through the positioning holes.

[0047] In some embodiments of the present invention, the blowing mechanism 6 includes a fourth detection device and a blowing device 61. The fourth detection device is electrically connected to the controller. The fourth detection device is aligned with the conveyor belt 2 and is used to detect whether the positioning mechanism 3 that failed to pick up the material has reached the blowing mechanism 6. When the positioning mechanism 3 reaches the picking mechanism 5, the fourth detection device sends a signal to the controller, and the controller controls the blowing device 61 to blow the bolt fixing position 31, so that the bolts in the bolt fixing position 31 are blown out of the bolt fixing position 31, thereby improving the automation level of the blowing device 61. Furthermore, the fourth detection device can also detect whether there are still bolts in the bolt fixing position 31. If no bolts are present, the blowing device can be deactivated to reduce energy consumption.

[0048] Specifically, the first detection device 52 , the second detection device 11 , the third detection device and the fourth detection device all include photoelectric sensors or infrared sensors.

[0049] In some embodiments of the present invention, the blowing mechanism 6 includes multiple blowing pipes and a first collecting box. The number of the blowing pipes is set corresponding to the number of bolt fixing positions 31. The blowing pipes and the conveyor belt 2 are set perpendicular to each other, so that the bolts can be blown out of the conveyor belt 2 area smoothly; the blowing pipe is also connected to an air pump. When the air pump is started, the blowing pipe blows air outward. The first collecting box is set on one side of the blowing direction of the blowing pipe. The opening of the first collecting box faces upward to receive the bolts hanging down from the bolt fixing position 31.

[0050] In some embodiments of the present invention, a feeding gun unloading mechanism 7 is further included, and after the feeding gun 51 fails to pick up materials, the bolts arrive at the feeding gun unloading mechanism 7 to unload the bolts after the failure of picking up materials; the feeding gun unloading mechanism 7 is arranged on one side of the feeding station 22, and the feeding gun unloading mechanism 7 includes an inclined guide plate 71 and a second collection box 72 arranged in the inclined direction of the guide plate 71. After the feeding gun 51 loosens the bolts, the bolts will fall into the second collection box 72 under the guidance of the guide plate 71, completing the collection of waste materials.

[0051] The present invention also provides a method for loading vehicle body bolts, using the vehicle body bolt loading device of any one of the above embodiments, comprising the following steps:

[0052] S1: At the loading station 21, the vibration plate 1 arranges the bolts in order and sequentially transports them to the bolt fixing positions 31 on the positioning mechanism 3;

[0053] S2: The conveyor belt 2 transports the positioning mechanism 3 loaded with bolts to the material taking station 22;

[0054] S3: The fixing mechanism 4 fixes the bolts in the positioning mechanism 3, and the material extraction gun 51 extracts the bolts in the bolt fixing position 31;

[0055] S4: The first detection mechanism detects whether the material picking gun 51 is successful in picking up the material. If successful, the material picking gun 51 moves to the body processing position for bolt fixing; if unsuccessful, the material picking gun 51 picks up the material again at the remaining bolt fixing position 31;

[0056] S5: The positioning mechanism 3 that has successfully taken the material returns to the vibration plate 1 to reload the bolts; the positioning mechanism 3 that has failed to take the material returns to the blowing mechanism 6 to unload the remaining bolts, and after unloading is completed, returns to the vibration plate 1 to reload the bolts.

[0057] According to the above method, when working, the vibration plate 1 arranges the bolts and sends them to the bolt fixing position 31 on the positioning mechanism 3. After the positioning mechanism 3 is filled with bolts on the loading station 21, it is sent to the picking station 22 by the conveyor belt 2. After arriving at the picking station 22, the abutment arm 41 of the fixing mechanism 4 moves toward the positioning mechanism 3 to fix the bolts. The picking gun 51 moves down to the bolt fixing position 31 to take out the bolts and then moves up. The first detection device 52 detects the picking gun 51. If the bolts on the picking gun 51 are well fixed and the number is correct, the picking gun 51 is directly Then the bolts are sent to the next car body processing process, and the positioning mechanism 3 returns to the vibration disk 1 to reload; if the number of bolts on the feeding gun 51 is insufficient or the bolt position is inaccurate, a signal is sent to the control to notify the feeding gun 51 to reload. After the feeding gun 51 unloads the old material, it re-absorbs the new bolts in the remaining bolt fixing position 31 of the positioning mechanism 3, and is inspected again by the first detection device 52. After the feeding is completed, the positioning mechanism 3 first returns to the blowing mechanism 6 to blow off the bolts that cannot be taken out, and then reaches the vibration disk 1 to reload and enter the next cycle. The automatic bolt feeding device of the present application has a detection mechanism, and the feeding gun 51 is detected after the feeding gun 51 takes the material to prevent the feeding gun 51 from failing to take the material or the appearance of the bolts that cannot be taken on the conveyor belt 2, which will cause the entire process to be disordered, thereby ensuring the efficiency of the automatic bolt supply, and further ensuring the efficiency of the overall car body production, improving the product quality of the car body, and ensuring the economic benefits of the product.

[0058] In some embodiments of the present invention, in S1 , a second sensor device is first used to detect whether the bolt is accurately fixed in the bolt fixing position 31 .

[0059] In some embodiments of the present invention, in S3 , before the fixing mechanism 4 fixes the bolt, a third sensor device is used to detect whether the fixing mechanism 4 is in place.

[0060] In some embodiments of the present invention, in S5 , before blowing the material, the blowing mechanism 6 first detects whether the positioning mechanism 3 reaches one side of the blowing mechanism 6 through a fourth sensing device.

After the bolts are taken out from the bolt fixing position 31, they are moved upwards, and the first detection device 52 detects the material picking gun 51. If the bolts on the material picking gun 51 are well fixed and the quantity is correct, the material picking gun 51 directly sends the bolts to the next body processing process, and the positioning mechanism 3 returns to the vibration plate 1 to reload; if the number of bolts on the material picking gun 51 is insufficient or the bolt position is inaccurate, a signal is sent to the control to notify the material picking gun 51 to re-pick up the material. After the material picking gun 51 unloads the old material, it re-absorbs the new bolts in the remaining bolt fixing position 31 of the positioning mechanism 3, and passes the inspection of the first detection device 52 again.
