Description

Technical Field

[0001] This invention relates to the field of anti-collision and cushioning technology, specifically to a cuttlebone-inspired gradient anti-collision plate, an anti-collision cushioning bag, and a manufacturing method thereof. Background Technology

[0002] In modern transportation, industrial production, and daily life, collisions are difficult to completely avoid. As a key component for reducing collision damage, the performance of impact buffers is crucial. Most existing impact buffers use a single structure and material, resulting in limited cushioning effectiveness when facing impacts of varying intensities and directions. They cannot fully absorb collision energy, leading to inadequate protection for the object being protected. Traditional impact buffers use a single-layer honeycomb wall bonded together, resulting in unstable impact resistance, low controllability, and poor overall impact cushioning performance.

[0003] Cuttlefish bone has a unique microstructure composed of many regularly arranged air chambers. These chambers can deform and collapse in stages when subjected to external forces, thus effectively absorbing energy. This structure provides a new approach to the design of impact-absorbing cushioning packs.

[0004] Therefore, to address the above problems, a cuttlebone-like gradient anti-collision plate, an anti-collision buffer bag, and a manufacturing method are proposed to solve these problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention develops a cuttlebone-inspired gradient anti-collision plate and anti-collision buffer pack. This invention can disperse collision energy, smoothly attenuate the impact force of the collision, and is lightweight, easy to replace, and economical.

[0006] To achieve the above objectives, the present invention employs the following technical solution:

[0007] A cuttlebone gradient-inspired anti-collision plate includes a collision plate and a support plate. The surfaces of the collision plate and the support plate are parallel to each other. Several rows of buffer plates are connected between the collision plate and the support plate. The end of the buffer plate connected to the collision plate is the collision end, and the end of the buffer plate connected to the support plate is the support end. The curves of the collision end and the support end of the buffer plate exhibit different triangular wave function curves, and the curves of the collision end or the support end of adjacent buffer plates are symmetrically arranged.

[0008] Preferably, the formula for the triangular wave function curve of the collision end of the buffer plate is:

[0009] ,

[0010] Where A represents the amplitude of the collision, T represents the period of the collision, and t represents the independent variable.

[0011] Preferably, the formula for the triangular wave function curve of the support end of the buffer plate is:

[0012] ,

[0013] in, Indicates the amplitude at the support end, The period of the support end is represented by t, and the independent variable is represented by t.

[0014] Preferably, the period T at the collision end and the period at the support end are... The values ​​are the same, and peak point and exist The points at that location are located on the same vertical plane. Valley point and exist The points at the given values ​​lie on the same vertical plane. Similarly, when the t values ​​are equal, the corresponding values ​​on the two curves lie on the same vertical plane and are connected through... curves and The lofting operation of the curve yields the irregular surface of the buffer plate.

[0015] Preferably, the collision plate, support plate and buffer plate are all made of aluminum alloy.

[0016] The present invention also provides a collision buffer bag, including the above-mentioned imitation squid bone gradient collision plate, and a shell. An outer partition is provided at the front end of the outer side of the shell, and a connecting base plate is provided at the rear end of the outer side of the shell away from the outer partition. Several rows of parallel and connected collision plates are arranged inside the shell along the length direction connecting the outer partition and the connecting base plate. The collision plate of the collision plate is close to the side of the outer partition, and the support plate of the collision plate is close to the side of the connecting base plate. The collision plates and support plates of adjacent collision plates are attached and connected as a whole. Side buffers are provided on both sides inside the shell, and the length direction of the side buffers is perpendicular to the length direction of the collision plates inside the shell.

[0017] Preferably, the outer shell is provided with a light buffer zone, a medium buffer zone, and a heavy buffer zone, which are arranged sequentially along the length of the anti-collision buffer pack and separated by transverse partitions. Anti-collision plates are all set in the light, medium, and heavy buffer zones. The periods of the triangular wave function curves at both ends of the buffer plates of the anti-collision plates in the light, medium, and heavy buffer zones are different. Among them, the period of the triangular wave function curves at both ends of the buffer plates of the anti-collision plates in the light buffer zone is the longest, the period of the triangular wave function curves at both ends of the buffer plates of the anti-collision plates in the heavy buffer zone is the shortest, and the period of the triangular wave function curves at both ends of the buffer plates of the anti-collision plates in the medium buffer zone is in between the two.

[0018] Preferably, it also includes bending plates, the outer partition is configured as an arch, and a plurality of bending plates are evenly arranged in the gap between the bottom of the arch and the outer shell, the bending plates being used to assist in supporting the outer partition.

[0019] Preferably, it also includes a longitudinal partition, which is disposed in the middle of the housing, with its length direction parallel to the connection direction between the outer partition and the connecting bottom plate, and the two ends of the longitudinal partition are respectively connected to the outer partition and the connecting bottom plate, and divide the light buffer zone, the medium buffer zone and the heavy buffer zone into left and right parts.

[0020] The present invention also provides a manufacturing method for manufacturing the above-mentioned imitation squid bone gradient anti-collision plate, comprising the following steps:

[0021] Step 1: Convey the aluminum foil to be processed to the processing position and limit the aluminum foil to ensure that the aluminum foil is in the preset processing position during the processing;

[0022] Step 2: Stamp the aluminum foil from one end using a stamping die, and then perform plastic processing on the aluminum foil in steps along its length to complete the processing of the buffer plate;

[0023] Step 3: The buffer board, after plastic forming, is moved to the cutting position. The buffer board is then cut according to manufacturing requirements to obtain the target length of the buffer board.

[0024] Step 4: The cut buffer board is moved to the pre-transfer position, where it is clamped by a robotic arm and transferred to the assembly workshop conveyor line, so that the buffer board is moved to the assembly position.

[0025] Step 5: Lay the support plate flat, apply strong adhesive to the support end of the buffer plate, and then bond the buffer plate to the support plate. Arrange several rows of buffer plates on the support plate as needed, with adjacent buffer plates arranged symmetrically. Apply strong adhesive to the collision end of each row of buffer plates, and then place the collision plate on the buffer plate and bond it to the buffer plate. After the strong adhesive dries, remove the anti-collision plate to complete the manufacturing of one layer of anti-collision plate.

[0026] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solution has the following advantages:

[0027] 1. The present invention uses a cuttlebone-like gradient structure for the anti-collision plate. Compared with the traditional honeycomb structure anti-collision plate, it can achieve step-by-step deformation and collapse, effectively absorb energy, and provide better protection. Moreover, the cuttlebone-like gradient structure anti-collision plate is more stable during the collision, resulting in better stability after the collision.

[0028] 2. By setting different buffer zones, this invention avoids the need to replace all the anti-collision plates after impacts with different impact forces. That is, only the anti-collision plates of the deformed buffer zone need to be replaced, or the anti-collision plates of the unaffected buffer zone can be removed for reuse, thus improving the overall economy. Furthermore, by setting longitudinal partitions, each buffer zone is divided into left and right parts again, so as to avoid the need to replace the entire anti-collision plate of the buffer zone after a collision on one side. Only the anti-collision plate on the corresponding buffer zone side needs to be replaced, which further reduces costs and improves economic efficiency. Attached Figure Description

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] like Figures 1-8 As shown, a cuttlebone gradient-inspired anti-collision plate includes a collision plate 1 and a support plate 2. The surfaces of the collision plate 1 and the support plate 2 are parallel to each other and of the same size. Several rows of buffer plates 3 are uniformly connected between the collision plate 1 and the support plate 2. The end of the buffer plate 3 connected to the collision plate 1 is the collision end 31, and the end of the buffer plate 3 connected to the support plate 2 is the support end 32. The curves of the collision end 31 and the support end 32 of the buffer plate 3 exhibit different triangular wave function curves.

[0048] In this embodiment, the curves of the collision end 31 or support end 32 of adjacent buffer plates 3 are symmetrically arranged, that is, the curves of the collision end 31 of adjacent buffer plates 3 are opposite in direction, and the curves of the support end 32 of adjacent buffer plates 3 are opposite in direction.

[0049] Example 2

[0050] like Figure 6 As shown, the formula for the triangular wave function curve of the collision end 31 of the buffer plate 3 is:

[0051] ,

[0052] Where A represents the amplitude of the collision, T represents the period of the collision, and t represents the independent variable.

[0053] In this embodiment, as Figure 7 As shown, the formula for the trigonometric wave function curve of the support end 32 of the buffer plate 3 is:

[0054] ,

[0055] in, Indicates the amplitude at the support end, The period of the support end is represented by t, and the independent variable is represented by t.

[0056] In this embodiment, the period T of the collision end 31 and the period of the support end 32 are... The values ​​are the same. The value satisfies Where x is the amplitude ratio, which can be freely selected as needed. peak point and exist The points at that location are located on the same vertical plane. Valley point and exist The points at the given values ​​lie on the same vertical plane. Similarly, when the t values ​​are equal, the corresponding values ​​on the two curves lie on the same vertical plane and are connected through... curves and The lofting operation of the curve yields the irregular surface of the buffer plate 3, as shown below. Figure 5 and Figure 8 As shown.

[0057] Example 3

[0058] Based on Example 2, x is set to 4, that is... The value is one-quarter of the value of A.

[0059] In this embodiment, the collision plate 1, the support plate 2 and the buffer plate 3 are all made of 3-series aluminum alloy material, specifically 0.04mm aluminum foil.

[0060] Collision tests were conducted on a single-layer imitation squid bone gradient impact plate and a single-layer honeycomb structure impact plate. The distance between the close-to-each sides of the impact plate and support plate of the imitation squid bone gradient impact plate was 63.15 mm, and the distance between the centerlines of the buffer plates 3 was 42 mm. The peak value of the function curve at the impact end 31 of the buffer plate 3 was 15 mm, and the peak value of the function curve at the support end 32 of the buffer plate 3 was 4 mm. The inner thickness of the honeycomb structure impact plate was 63.15 mm, and the side length of the regular hexagons in the honeycomb structure was 15 mm. The material used was 0.04 mm thick aluminum foil. The experimental conditions were quasi-static compression at 3 m / s. Figure 12 As shown in the figure, the force-displacement image at the collision end shows that, when comparing the two structures at the first peak force, the squid bone structure is slightly lower and there is no obvious peak force in the subsequent collision stage, while the honeycomb structure has obvious multi-level peak forces. Overall, the squid bone structure is more stable during the collision and has a lower force value.

[0061] Example 4

[0062] like Figure 9 As shown, a collision buffer pack includes several collision plates with the aforementioned squid bone gradient, and also includes a shell 4. An outer partition 5 is provided at the front end of the outer side of the shell 4, and a connecting base plate 6 is provided at the rear end of the outer side of the shell 4 away from the outer partition 5. The connecting base plate 6 is used to connect the fixed end of the vehicle body or other objects to fix the position of the collision buffer pack, so as to achieve support and fixation throughout the collision process. Several rows of parallel and connected collision plates are arranged inside the shell 4 along the length direction of the connection between the outer partition 5 and the connecting base plate 6. The collision plate 1 of the collision plate is close to the side of the outer partition 5, and the support plate 2 of the collision plate is close to the side of the connecting base plate 6. The collision plate 1 and the support plate 2 of adjacent collision plates are attached and connected as one piece. Preferably, a strong fixing adhesive is used to bond the collision plate 1 and the support plate. In an optional embodiment, side buffers 7 are provided on the sides of both sides inside the housing 4. The side buffers 7 can be made of squid bone-like anti-collision plates or traditional honeycomb anti-collision plates. The length direction of the side buffers 7 is perpendicular to the length direction of the anti-collision plates inside the housing 4, that is, the force direction of the side buffers 7 is perpendicular to the force direction of the anti-collision plates inside the housing, so as to achieve lateral buffer protection when the anti-collision buffer pack is hit, and the safety is better.

[0063] Example 5

[0064] like Figures 10-11As shown, based on Embodiment 4, a light buffer zone 41, a medium buffer zone 42, and a heavy buffer zone 43 are provided inside the outer shell 4. The light buffer zone 41, the medium buffer zone 42, and the heavy buffer zone 43 are arranged sequentially along the length of the anti-collision buffer pack, and are separated by a transverse partition 8. The two ends of the transverse partition 8 are connected to the outer shell 4, and the surface of the transverse partition 8 is connected to the anti-collision plate with strong fixing adhesive. The anti-collision plates are all set in the light buffer zone 41, the medium buffer zone 42, and the heavy buffer zone 43. The periods of the triangular wave function curves at both ends of the buffer plate 3 of the anti-collision plate in the light buffer zone 41, the medium buffer zone 42, and the heavy buffer zone 43 are all different. Among them, the period of the triangular wave function curve at both ends of the buffer plate 3 of the anti-collision plate in the light buffer zone 41 is the longest, the period of the triangular wave function curve at both ends of the buffer plate 3 of the anti-collision plate in the heavy buffer zone 43 is the shortest, and the period of the triangular wave function curve at both ends of the buffer plate 3 of the anti-collision plate in the medium buffer zone 42 is between the former two.

[0065] In an optional embodiment, the center distances between the buffer plates of the crash barriers in the light buffer zone 41, the medium buffer zone 42, and the heavy buffer zone 43 are also different. The center distance between the buffer plates of the crash barriers in the light buffer zone 41 is the largest, the center distance between the buffer plates of the crash barriers in the heavy buffer zone 43 is the smallest, and the center distance between the buffer plates of the crash barriers in the medium buffer zone 42 is in between the two.

[0066] In an optional embodiment, it also includes a bending plate 9. The outer partition 5 is configured as an arch, and a plurality of bending plates 9 are evenly arranged in the gap between the bottom of the arch and the outer shell 4. The bending plates 9 are used to assist in supporting the outer partition 5 and can guide the collision in the initial stage of the collision and correct the vehicle's collision posture.

[0067] When the aforementioned anti-collision buffer pack is impacted, the car first contacts the outer partition 5 at the front end of the buffer pack. The outer partition 5 guides the collision, making the impact more complete and correcting the car's collision posture. Further, the car compresses the light buffer zone 41, absorbing energy through the deformation of the anti-collision plates inside the light buffer zone 41. The collision intensity is low, and the deformation mainly occurs in the light buffer zone 41. The anti-collision plates of the other two buffer zones can be recycled for reuse. Further, the light buffer zone 41 cannot completely absorb the collision energy, and the car further intrudes into the anti-collision buffer pack, compressing the medium buffer zone 42. The deformation of the internal crash barrier of the moderate buffer zone 42 absorbs energy, resulting in a relatively high collision intensity. The deformation mainly occurs in the light buffer zone 41 and the moderate buffer zone 42. The crash barrier of the severe buffer zone 43 can be recycled and reused. Furthermore, the light buffer zone 41 and the moderate buffer zone 42 cannot completely absorb the collision energy, so the car further intrudes into the crash buffer pack, compressing the severe buffer zone 43. The energy is absorbed through the deformation of the internal crash barrier of the severe buffer zone 43, resulting in the highest collision intensity. The entire crash buffer pack fully impacts the collision, completing the energy absorption task and protecting the lives of drivers and road maintenance workers.

[0068] Collision tests were conducted on two types of impact buffer packs: one using imitation squid bone gradient impact plates and the other using honeycomb structure impact plates. The two types of impact buffer packs were identical except for their internal structure. In the imitation squid bone gradient impact plate impact buffer pack, the spacing between the buffer plates in the light buffer zone 41 was 58 mm with a period of 50 mm; in the medium buffer zone 42, the spacing was 50 mm with a period of 40 mm; and in the heavy buffer zone 43, the spacing was 42 mm with a period of 30 mm. The light buffer zone 41 contained 7 layers of imitation squid bone gradient impact plates, the medium buffer zone 42 contained 13 layers, and the heavy buffer zone 43 contained 22 layers. The peak value of the collision end function curve for each buffer plate was set to 15 mm, and the peak value of the support end function curve was set to 4 mm. The honeycomb structure impact buffer pack used conventionally used dimensions. The experimental collision conditions were a frontal collision with an 1100 kg rigid wall at 100 km / h. Figure 13 For the force-displacement image of the moving end of the anti-collision buffer pack, the two structures show almost constant peak force in the first stage. In subsequent collision stages, the squid-bone structure shows no obvious peak force, while the honeycomb structure shows obvious multi-level peak forces. Overall, the squid-bone structure is more stable during the collision process. Figure 14 The force-time graph of the fixed end of the anti-collision buffer pack shows that both the honeycomb structure and the imitation squid bone structure exhibit good regular fluctuations at the front end, and the force of the imitation squid bone structure is significantly smaller than that of the honeycomb structure overall.

[0069] Example 6

[0070] Based on Embodiment 5, a longitudinal partition 10 is also included, which is disposed in the middle of the outer shell 4. Its length direction is parallel to the connection direction between the outer partition 5 and the connecting base plate 6. The two ends of the longitudinal partition 10 are respectively connected to the outer partition 5 and the connecting base plate 6, and the light buffer zone 41, the medium buffer zone 42 and the heavy buffer zone 43 are all divided into two symmetrical parts to further avoid the waste of the anti-collision plates of each buffer zone and further improve the economy of use.

[0071] Example 7

[0072] A manufacturing method for producing the cuttlebone gradient anti-collision plate described in Example 3 includes the following steps:

[0073] Step 1: Convey the aluminum foil to be processed to the processing position and limit the aluminum foil to ensure that the aluminum foil is in the preset processing position during the processing;

[0074] Step 2: Stamp the aluminum foil from one end using a stamping die, and then perform plastic processing on the aluminum foil step by step along its length to complete the processing of the buffer plate;

[0075] Step 3: The buffer board, after plastic forming, is moved to the cutting position. The buffer board is then cut according to manufacturing requirements to obtain the target length of the buffer board.

[0076] Step 4: The cut buffer board is moved to the pre-transfer position, where it is clamped by a robotic arm and transferred to the assembly workshop conveyor line, so that the buffer board is moved to the assembly position.

[0077] Step 5: Place the support plate flat in the assembly position, apply strong fixing adhesive to the support end of the buffer plate, and then bond the buffer plate to the support plate. Arrange several rows of buffer plates on the support plate as needed, with adjacent buffer plates arranged symmetrically. Apply strong fixing adhesive to the collision end of each row of buffer plates, and then place the collision plate on the buffer plate and bond it to the buffer plate. After the strong fixing adhesive dries, remove the anti-collision plate to complete the manufacturing of one layer of anti-collision plate.

[0078] Example 8

[0079] Based on Embodiment 7, the specific configuration of Step 1 is as follows: A conveying drive mechanism drives a conveying platform along a preset trajectory to transport the aluminum foil to be processed from the initial workstation to the processing area. The conveying drive mechanism includes a servo motor and a transmission assembly connected thereto. The transmission assembly includes a drive pulley connected to the output shaft of the servo motor, a driven pulley located at the bottom of the conveying platform, and a transmission belt wound between the drive pulley and the driven pulley. The conveying platform includes a horizontally positioned support plate, with support legs at the four corners of the bottom of the support plate, and the bottom ends of each support leg connected to a support device. The support device includes a fixed base and a shock-absorbing assembly located on top of the fixed base. The shock-absorbing assembly includes shock-absorbing springs and dampers connected to the bottom ends of the support legs to suppress vibrations generated during transport. A guide rail extending along the conveying direction is provided on the upper surface of the support plate, through which the aluminum foil to be processed passes. The aluminum foil is fixed to the guide rail by a clamp. The clamp includes a slider that slides with the guide rail and an elastic gripper on the top of the slider. The elastic gripper has a clamping part that adapts to the edge of the aluminum foil, and the inner side of the clamping part is provided with anti-slip texture. The conveying drive mechanism also includes a controller, which is electrically connected to a servo motor to control the speed and direction of the servo motor, so as to achieve precise control of the conveying speed and position of the conveying platform. The controller is also electrically connected to a position sensor located at the entrance of the processing area. When the position sensor detects that the aluminum foil has arrived at the entrance of the processing area, the controller sends a signal to the servo motor, causing the servo motor to decelerate and stop running, and precisely positioning the aluminum foil to the preset processing position in the processing area. After the aluminum foil to be processed is conveyed to the processing area through the conveying step, the positioning mechanism in the processing area limits and fixes the aluminum foil to ensure that the aluminum foil is in the preset processing position during the processing.

[0080] The specific steps for step two are as follows: The processing device is started. The processing device includes a stamping assembly and a control system, wherein the control system is electrically connected to the first human-machine interface. The operator inputs the structural parameters of the buffer plate through the first human-machine interface. The structural parameters include, but are not limited to, the curve parameters at both ends of the buffer plate, the wall thickness, and the unit arrangement density, and each parameter is adapted to the bio-structural characteristics of the imitation cuttlebone. The first human-machine interface converts the input parameters into electrical signals and transmits them to the control system. The control system generates drive commands based on the received parameter signals, controlling the stamping pressure, stamping frequency, and feed speed of the stamping assembly respectively. The positioned aluminum foil is subjected to step-by-step plastic processing to sequentially complete the forming of the buffer plate and the integral forming of the gradient structure. During the processing, the control system collects the operating parameters of the processing device in real time and feeds them back to the first human-machine interface. The operator can monitor the processing status in real time through the interface and dynamically adjust the parameters when necessary. After processing is completed, the processing device automatically resets, forming a buffer plate with preset structural parameters.

[0081] The specific settings for step three are as follows: The buffer plate formed in the processing steps is transported to the cutting area along a preset conveying path by the transport platform. The cutting area is equipped with a cutting device, which includes a frame, a cutting execution component, a drive component, and a control unit. The control unit is electrically connected to the second human-machine interface. A photoelectric sensor for detecting the position of the buffer plate is installed at the entrance of the cutting area. The photoelectric sensor is electrically connected to the control unit. When the photoelectric sensor detects that the front end of the buffer plate has reached the preset starting position of the cutting area, it sends a trigger signal to the control unit. According to the overall layout requirements of the anti-collision buffer pad, the operator inputs the target length parameter of the buffer plate through the second human-machine interface. The target length parameter includes the length of the buffer plate body and the processing allowance reserved at both ends. The second human-machine interface converts the length parameter into a digital signal and transmits it to the control unit. After receiving the trigger signal and length parameter signal, the control unit calculates the distance the buffer plate needs to be moved and sends a drive command to the drive assembly. The drive assembly includes a stepper motor and a ball screw transmission pair, which drive the cutting execution assembly to move perpendicular to the conveying direction. The cutting execution assembly includes a mounting frame and a cutting tool set at the bottom of the mounting frame. When the buffer plate is moved to the target cutting position, the control unit sends a braking signal to the drive mechanism of the conveying platform to stop the conveying platform and simultaneously controls the cutting execution assembly to move. The cutting tool moves down along a preset trajectory under the drive of the drive assembly to complete the cutting operation of the buffer plate. After the cutting is completed, the control unit controls the cutting execution assembly to reset and sends a start signal to the drive mechanism of the conveying platform to make the conveying platform continue to run and move the cut buffer plate to the exit of the cutting area.

[0082] The specific settings for step four are as follows: After the cutting step, the buffer plate continues to be conveyed along its length by the transport platform until it is transferred to the preset transfer station at the rear of the transport platform. A position detection unit is installed at the rear of the transport platform, including a laser displacement sensor, which is electrically connected to the main controller of the transport platform. When the laser displacement sensor detects that the buffer plate has completely entered the transfer station, it sends a position signal to the main controller. After receiving the signal, the main controller controls the transport platform to stop. A robotic arm is fixedly installed at the rear of the transport platform. The robotic arm includes a base, a multi-degree-of-freedom articulated arm, and an end effector. The base is fixedly connected to the support device of the transport platform by bolt assemblies. The articulated arm is driven by a servo motor, and each joint is equipped with an angle encoder for real-time feedback of the joint rotation angle and precise positioning. The end effector includes a mounting base and a pneumatic gripper located at the bottom of the mounting base. The gripping surface of the pneumatic gripper has an elastic buffer layer made of silicone material, and its surface has a concave-convex structure adapted to the outer contour of the buffer plate. To avoid damage to the buffer plate during clamping, the robotic arm is electrically connected to the main controller. When the transport platform stops operating, the main controller sends a transfer command to the robotic arm. Upon receiving the command, the robotic arm moves the end effector above the buffer plate through the coordinated movement of the articulated arms. The pneumatic gripper opens under the drive of the air source device and then descends to the preset clamping height. The pneumatic gripper then closes to clamp the buffer plate. The clamping force is monitored in real time by a pressure sensor and fed back to the main controller to ensure that the clamping force is within the preset threshold range. After clamping, the robotic arm drives the end effector and the buffer plate to move along a preset path. The preset path is determined by the motion trajectory parameters pre-stored in the main controller. These parameters include the three-dimensional coordinate information from the transfer station to the assembly workshop feeding conveyor belt. When the robotic arm moves the buffer plate above the preset placement position on the assembly workshop feeding conveyor belt, the pneumatic gripper opens under the control of the main controller and places the buffer plate on the conveyor belt.
