[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings required for the description of the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some examples or embodiments of the present application. For those of ordinary skill in the art, without creative efforts, the present application can also be applied to other similar scenarios based on these drawings. Unless obvious from the language context or otherwise stated, the same reference numerals in the drawings represent the same structure or operation.

[0019] This application describes a calibration mechanism that can be used for FDS device calibration, reducing the device's dependence on engineers during calibration and improving the device's intelligence during the calibration process. This mechanism allows the FDS device to move between a preset position on the calibration mechanism and its original working position based on a movement trajectory. With the support of the calibration mechanism, the FDS device can complete automatic calibration, thereby increasing the calibration speed and reducing the failure rate.

[0020] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of the calibration mechanism in some embodiments of the present application. The calibration mechanism 100 may include a calibration frame 10, a storage box 20 disposed on the calibration frame 10, and a calibration component 30 disposed on the calibration frame 10. The calibration frame 10 can support the storage box 20 and the calibration component 30, facilitating the cooperation of the storage box 20 and the calibration component 30 during the calibration process of the FDS device. The storage box 20 can be used to store nails discarded by the FDS device during the calibration process. The calibration component 30 is used to calibrate the FDS device. During the calibration process of the FDS device, the FDS device moves from its original working position to above the storage box 20, discards the nails that affect the calibration structure into the storage box 20, and then moves to a preset position of the calibration mechanism 100. Calibration is performed with the cooperation of the calibration component 30, and the calibration is completed. Therefore, the calibration process of the FDS device is standardized through the calibration mechanism 100, such as the storage box 20 and the calibration component 30, thereby improving the calibration speed of the FDS device and reducing the failure rate.

[0021] See also Figure 1 The calibration frame 10 can be fixed to a structure that facilitates FDS equipment calibration. The specific location can be determined based on factors such as the workshop environment, the requirements for cooperation with the FDS equipment, and the limitations of the workpiece, which will not be described in detail. For example, the calibration frame 10 can be fixed to a processing lathe. For example, the calibration frame 10 can be fixed to the ground.

[0022] The calibration frame 10 may include a main frame 11 and a transfer fixture 12 movably connected to the main frame 11 .

[0023] The main frame 11 can be a frame structure, a column structure or a shell structure, etc., and can also be other types of structures, which will not be described in detail. The main frame 11 can be used to fix the storage box 20 and the calibration component 30.

[0024] The main frame 11 may include a base 111 , a column 112 fixed on the base 111 , and a rib 113 connecting the base 111 and the column 112 .

[0025] The base 111 can be fixed to the adapter fixture 12 via a detachable connection. For example, the base 111 can be fixed to the adapter fixture 12 via plugging, snapping, or screwing. Of course, in some scenarios, the base 111 can also be directly fixed to a structure that facilitates FDS device calibration. In some scenarios, the base 111 can also be fixed to a structure that facilitates FDS device calibration via a detachable connection.

[0026] The column 112 can be directly fixed to the base 111. In some embodiments, the column 112 can be integral with the base 111. In some embodiments, the column 112 can be connected to the base 111 by welding, screwing, etc. In some embodiments, the column 112 can extend to a side away from the base 111.

[0027] The ribs 113 are located on the side of the base 111 facing the column 112 and are fixedly connected to the column 112. At the same time, they are also fixedly connected to the base 111 to strengthen the connection strength between the base 111 and the column 112. In some embodiments, there are multiple ribs 113, and they can be arranged around the column 112.

[0028] The adapter fixture 12 can be detachably connected to the main frame 11, such as the base 111, and the adapter fixture 12 can realize the fixation of the main frame 11, such as the base 111, on different structures. In some scenarios, when the calibration mechanism 100 is installed on different structures, it is necessary to consider whether the calibration mechanism 100 and the structure are compatible. When the main frame 11, such as the base 111, cannot be directly installed on the structure, the main frame 11, such as the base 111, and the structure can be connected by the adapter fixture 12 to realize the installation of the main frame 11, such as the base 111, on the structure.

[0029] The types of the adapter fixture 12 can be various and can be set according to actual needs. In some scenarios, one or more adapter fixtures 12 can be sufficient to match the structure, so that the calibration mechanism 100 can be installed on different structures through the adapter fixtures 12.

[0030] In some embodiments, the adapter fixture 12 can be located on a side of the base 111 facing away from the column 112, and the column 112 can extend toward a side away from the base 111. There can be multiple adapter fixtures 12 with varying thicknesses. Based on thickness requirements, the appropriate adapter fixture 12 can be selected to adjust the height of the column 112 in the extension direction to match the FDS device and facilitate FDS device calibration.

[0031] In some embodiments, the orthographic projection of the base 111 on the adapter fixture 12 falls within the range of the adapter fixture 12 .

[0032] In some embodiments, the adapter fixture 12 may be omitted, and the main frame 11 , such as the base 111 , may be fixed to a structure that facilitates calibration of the FDS device.

[0033] See also Figure 1 and Figure 2 , Figure 2 for Figure 1 Schematic diagram of the partial structure of the calibration mechanism 100 in the illustrated embodiment. The storage box 20 can collect the nail bodies discarded by the FDS device, improve the situation of random discarding and waste of the nail bodies, and make the collected nail bodies available for reuse. The storage box 20 can be fixed directly or indirectly to the calibration frame 10, such as the main frame 11. In some embodiments, the storage box 20 can be fixed to the main frame 11 by a detachable connection. For example, the storage box 20 can be fixed to the calibration frame 10, such as the main frame 11, by plugging, snapping, or screwing. In some embodiments, the storage box 20 can be fixed to the column 112, and can be closer to the end of the column 112 facing away from the base 111.

[0034] See also Figure 1 and Figure 2 The calibration component 30 can be used to calibrate the FDS device. The calibration component 30 may include an adjustment member 31 and a calibration member 32 fixed to the calibration frame 10, such as the main frame 11. The calibration member 32 serves as the main calibration component of the calibration component 30 and is used to calibrate the FDS device. The adjustment member 31 can be used to adjust the position of the calibration member 32 to better align with the FDS device during calibration.

[0035] See also Figure 2 The adjusting member 31 may be a plate-like structure or a frame structure, and may be fixed to the calibration frame 10, such as the main frame 11, by welding, bonding, screwing, snapping, or plugging. Of course, it may also be connected in other ways. In some embodiments, the adjusting member 31 may be a part of the calibration frame 10, such as the main frame 11. In some embodiments, the adjusting member 31 may be fixed to the column 112. In some embodiments, the adjusting member 31 may be a part of the column 112, or may be an integral structure with the column 112.

[0036] The adjusting member 31 may be provided with a plurality of adjusting holes 3111, so as to be detachably connected to the calibration member 32 through the adjusting holes 3111. By cooperating with the calibration member 32 through different adjusting holes 3111, the position of the calibration member 32 can be adjusted.

[0037] In some embodiments, the plurality of adjustment holes 3111 are arranged in a first direction, thereby enabling adjustment of the position of the calibration member 32 in the first direction. In some embodiments, the first direction may be the direction in which the main frame 11 is away from the adapter fixture 12. In some embodiments, the first direction may be a vertical direction. In some embodiments, the first direction may be the direction in which the column 112 extends. It is understood that the first direction may also be other directions, which can be set according to specific needs and are not further described.

[0038] In some scenarios, the first direction is a vertical direction, and thus, the adjusting member 31 can adjust the height of the calibrating member 32 in the vertical direction, and the height adjustment of the calibrating member 32 in the vertical direction can be achieved through the adjusting hole 3111 .

[0039] In some embodiments, the types of the adjusting member 31 can be various and can be set according to actual needs. In some scenarios, the position of the calibration member 32 can be adjusted by detachably connecting one or more suitable adjusting members 31 to the calibration member 32.

[0040] In some embodiments, the adjusting member 31 and the storage box 20 may be located on opposite sides of the main frame 11 , such as the column 112 .

[0041] In some embodiments, the adjustment member 31 may be omitted, and the calibration member 32 may be directly disposed on the calibration frame 10 , such as the main frame 11 , for example, on the column 112 .

[0042] See also Figure 2 , the calibration piece 32 may be a frame structure, a plate structure or other structure that may have a calibration surface 3221, which will not be elaborated. The calibration piece 32 can be calibrated with the FDS equipment through the calibration surface 3221. The calibration piece 32 can be directly or indirectly fixed to the calibration frame 10, such as the main frame 11. In some embodiments, the calibration piece 32 can be fixed to the main frame 11 by a detachable connection. For example, the calibration piece 32 can be fixed to the calibration frame 10, such as the main frame 11, by plugging, snapping or screwing. In some embodiments, the calibration piece 32 can be fixed to the column 112, and can be closer to the end of the column 112 on the side away from the base 111.

[0043] In some embodiments, the calibration member 32 may be located on the side of the storage box 20 away from the base 111 in the first direction. In some scenarios, the projected area of the calibration member 32 in the first direction is smaller than the projected area of the opening of the storage box 20 in the first direction. In some embodiments, the calibration member 32 may be located on the side of the storage box 20 away from the base 111 in the first direction. In some scenarios, the projected area of the calibration member 32 in the first direction is smaller than the projected area of the opening of the storage box 20 in the first direction. In some scenarios, the projection of the calibration member 32 in the first direction and the projection of the opening of the storage box 20 in the first direction partially overlap in the first direction, facilitating the faster movement of the FDS device, for example, moving from the position corresponding to the storage box 20 to the preset position corresponding to the calibration member 32. In some scenarios, the projection of the calibration member 32 in the first direction is located within the projection of the opening of the storage box 20 in the first direction. In some scenarios, the ratio of the projected area of the calibration member 32 in the first direction to the projected area of the opening of the storage box 20 in the first direction is between 0.2 and 0.5, avoiding excessive covering of the storage box 20 by the calibration member 32 so as not to affect the calibration process of the FDS device.

[0044] The calibration member 32 may include a fixed main body 321 and a calibration main body 322 provided with a calibration surface 3221. The fixed main body 321 is fixedly connected to the calibration main body 322. The fixed main body 321 can realize the fixed connection of the calibration member 32 to other structures in the calibration mechanism 100.

[0045] The fixed main body 321 can be fixed on the adjusting member 31 by a detachable connection method. For example, the fixed main body 321 can be fixed on the adjusting member 31 by plugging, clamping or screwing, etc. In some embodiments, the fixed main body 321 can be fixed on the adjusting member 31 by a nail body such as a bolt or a pin passing through the adjusting hole 3111.

[0046] The calibration main body 322 can be a plate-like structure or other structures with a calibration surface 3221, which will not be elaborated. The calibration main body 322 can be located on the side of the fixed main body 321 away from the base 111, and a calibration surface 3221 is provided on the side away from the fixed main body 321. In some embodiments, the calibration main body 322 and the fixed main body 321 can be formed by bending a plate body.

[0047] The calibration main body 322 can be connected to the fixed main body 321 and extend towards the side close to the storage box 20. In some scenarios, the calibration main body 322 extends towards the side close to the storage box 20 such that the projection of the calibration member 32 in the first direction overlaps with the projection of the opening of the storage box 20 in the first direction. Of course, it can also make the projection of the calibration member 32 in the first direction be located within the projection of the opening of the storage box 20 in the first direction.

[0048] In some embodiments, the calibration body 322 may be located on a side of the main frame 11 facing away from the adapter fixture 12 .

[0049] In some embodiments, the calibration mechanism 100 , for example, the calibration body 322 , can withstand a pressure of no less than 3000N.

[0050] In some embodiments, the calibration surface 3221 may be disposed on a side of the calibration body 322 facing away from the base 111. In some embodiments, the projection area of the calibration surface 3221 in the first direction may be smaller than the projection area of the opening of the storage box 20 in the first direction.

[0051] In some embodiments, the calibration surface 3221 may be disposed on a side of the calibration body 322 facing away from the storage box 20. In some scenarios, the projected area of the calibration surface 3221 in the first direction is smaller than the projected area of the opening of the storage box 20 in the first direction. In some scenarios, the projected area of the calibration surface 3221 in the first direction partially overlaps with the projected area of the opening of the storage box 20 in the first direction, facilitating faster movement of the FDS device, for example, from a position corresponding to the storage box 20 (a nail ejection position) to a preset position corresponding to the calibration surface 3221. In some scenarios, the projected area of the calibration surface 3221 in the first direction lies within the projected area of the opening of the storage box 20 in the first direction. In some scenarios, the ratio of the projected area of the calibration surface 3221 in the first direction to the projected area of the opening of the storage box 20 in the first direction is between 0.2 and 0.5, to prevent the calibration surface 3221 from excessively covering the storage box 20 and affecting the calibration process of the FDS device.

[0052] In some embodiments, a positioning portion 3222 may be provided on the calibration surface 3221 , and the positioning portion 3222 may be used to position the FDS device on the calibration surface 3221 , so that the FDS device can more quickly determine the preset position based on the positioning portion 3222 and complete the calibration.

[0053] In some embodiments, the positioning portion 3222 is provided with a positioning hole, a positioning groove, a positioning block or a protrusion located on the calibration surface 3221. Of course, other structural settings that can be used for positioning can also be made according to needs.

[0054] It is understood that structures such as positioning holes or positioning slots can also be used to test the calibration results of the FDS device. Furthermore, the structure provided with positioning holes or positioning slots can also be referred to as a testing portion. Of course, the testing portion can also be provided on a structure other than the positioning portion 3222 in the calibration mechanism 100, and the testing portion can be provided with a testing hole or testing slot. In some embodiments, the testing portion can be provided with a testing hole or testing slot located on the calibration surface 3221.

[0055] See also Figure 3 , Figure 3Schematic structural diagram of the calibration system in some embodiments of the present application. The calibration system may include a calibration mechanism 100 and an FDS device 200. The FDS device 200 may be the FDS device in the above embodiments and may be calibrated using the calibration mechanism 100. Specifically, the FDS device 200 may use the flow drill screw tightening process (FDS process) to achieve structural connection. When the FDS device 200 is operating, the main processes it can perform are pre-positioning, meshing, piercing, thread forming, and final tightening to connect two or more layers of plates to achieve structural connection. In some embodiments, the FDS device 200 may be a robot for connecting cold metal steel-aluminum hybrids, pure aluminum, etc.

[0056] In some scenarios, the FDS device 200 may be used to produce a steel-aluminum hybrid body, so that the steel-aluminum hybrid body combines the advantages of all-steel and all-aluminum bodies, achieving lightweight while ensuring collision energy absorption and collision force transmission, etc. Of course, the FDS device 200 may also be used to produce other products that use the FDS process to achieve structural connection, which will not be elaborated here.

[0057] The FDS device 200 may include an electric control cabinet (not shown in the figure), a nail feeder (not shown in the figure), a touch screen (not shown in the figure), and an execution unit (the gun head, i.e., the structure shown by the FDS device 200 in Figure 3 ). The electric control cabinet controls the FDS device 200 as a whole. The nail feeder can convey the nail body to the gun head under the control of the electric control cabinet. The gun head is the main execution tool for achieving structural connection using the nail body and can work under the control of the electric control cabinet. The touch screen can display the information related to the work of the FDS device 200 and can also issue commands to the electric control cabinet under the operation of the user to control the FDS device 200.

[0058] The gun head may include a pressure plate 201, a jaw 202, a tool shank 203, etc. During the operation of the gun head, the nail body is conveyed over, clamped by the jaw 202, the FDS device 200 drives the pressure plate 201 to press the workpiece to be processed, and then drives the tool shank 203 to perform a feeding motion and a rotational motion, mesh with the nail body, and complete piercing, tapping, and tightening.

[0059] When a fault occurs or there is an abnormal power outage in the FDS device 200, there will be an error in the servo position of the FDS device 200. If the servo position error is not eliminated, the FDS device 200 will report an error "not calibrated", and this type of fault cannot be reset. If the fault is not eliminated through the calibration of the FDS device 200, the device cannot work properly.

[0060] In addition, when the wearing parts in the gun head, such as the tool shank 203, the motor, the shaft structure, etc., are worn or replaced, if the FDS device 200 is not calibrated, when the FDS device 200 performs nail driving work, process errors such as cap searching failure and nails not being driven in will occur, resulting in unnecessary economic losses caused by equipment failures.

[0061] In the prior art, when calibrating the FDS device 200, engineers need to write programs on-site for teaching position calibration, which has a high dependence on engineers. In addition, calibrating on the vehicle body has poor practicability and a long calibration time, and improper operation may damage the gun head. Moreover, during calibration, the nail body is blown out to the ground through 0.5 - 0.7 MPA compressed air to ensure the line operation rate. The nails on the ground are not collected immediately, which is extremely likely to cause random discard and waste of the nail body.

[0062] In this application, when the FDS device 200 needs to be calibrated, during the calibration process, as Figure 3 shown, the gun head can be controlled to move to a position corresponding to the storage box 20 (the nail ejection position), and the nail body affecting the calibration process is ejected. The nail body falls into the storage box 20 and is collected by the storage box 20, so as to improve the random discard and waste of the nail body, and the collected nail body can be reused. As Figure 4 ( Figure 4 is Figure 3 shown in the structural schematic diagram of the calibration system in the embodiment), the gun head can be controlled to move to a preset position. At this time, the gun head is in a posture perpendicular to the calibration surface 3221. The pressure plate 201 extends downward and presses against the calibration surface 3221. The clamping jaw 202 opens, and the tool bar 203 slowly descends to contact the calibration surface 3221 and retracts after generating a certain pressure, completing the calibration action. During this process, the relative positions of the pressure plate 201 and the tool bar 203 are calibrated, and the FDS device 200 completes the servo internal operation to eliminate the servo position error, so that the FDS device 200 is in a fault-free state.

[0063] In some embodiments, when the gun head is at the nail ejection position, it can be in a vertical posture. In some embodiments, when the gun head is at the preset position, it can be 8 - 12 mm away from the calibration surface 3221. Of course, it can also be adjusted according to requirements. In some embodiments, when the gun head is at the preset position, it can be 10 mm away from the calibration surface 3221.

[0064] Please refer to Figure 4 , when the FDS device 200 uses the imaging device for visual positioning, the preset position can be determined through the positioning part 3222. In addition, testing can also be carried out using the testing part, so that the gun head is connected by inserting the nail body into the test hole or test groove, and the connection quality is determined by engineers or the imaging device, etc.

[0065] In this application, a program adapted to the nail ejection and calibration of the FDS device 200 can be uniformly written by engineers in advance to standardize the calibration process of the FDS device 200. When the FDS device 200 needs to be calibrated, it can be called with one key through the program, and the FDS device 200 automatically performs nail ejection, calibration actions and signal processing logic without manual intervention, avoiding collision phenomena and having a good improvement effect on improving the line operation rate. Under the control of the program, the FDS device 200 can move the gun head from the original working position to Figure 3 the nail ejection position above the storage box 20 shown in Figure 4 to eject nails, and then move to
