Technical Field

[0001] This utility model belongs to the technical field of spring assembly machines, and specifically relates to an automatic spring assembly machine. Background Technology

[0002] As a crucial component of mechanical products, the quality of spring assembly directly impacts the overall function and performance of the product. For example, in the automotive industry, springs are a key component of the suspension system, responsible for supporting the vehicle's weight and absorbing and cushioning impacts and vibrations from the road surface during driving. Properly assembled springs can significantly improve suspension performance, enhance ride comfort, and ensure vehicle stability, comfort, and handling.

[0003] A spring assembly machine is a device that uses mechanical devices and electrical control systems to automatically assemble springs. The main function of a spring assembly machine is to transport springs to the working area via a chain conveyor or vibratory feeder, and then automatically assemble components such as parts, circlips, torsion springs, and pressure plates into designated positions using robotic arms or various assembly modules to form finished springs.

[0004] Currently, existing spring assembly machines cannot control the posture of the springs during installation, and manual intervention is required in some cases, resulting in low efficiency and low assembly accuracy. Utility Model Content

[0005] The purpose of this invention is to provide an automatic spring assembly machine to address the problems mentioned above. It is hoped that the existing spring assembly machines can not limit the posture of the spring during installation, and that manual intervention is required in some cases, resulting in low efficiency and low assembly accuracy.

[0006] The technical solution adopted by this utility model is as follows: an automatic spring assembly machine, comprising: a sorting device for preliminary sorting of springs, the sorting device including a feeding tray, a spring sorting vibratory feeder and a conveying device, the feeding tray being disposed above the spring sorting vibratory feeder, the springs entering the spring sorting vibratory feeder through the feeding tray, the spring sorting vibratory feeder being connected to the conveying device, the conveying device being used to convey the springs, the spring sorting vibratory feeder and the conveying device jointly being used to limit the spring posture; and a loading robot for carrying springs for positional movement, the loading robot including a guide rail, a servo tightening shaft and a crank, the crank being connected to the servo tightening shaft; the servo tightening shaft being disposed on the guide rail through a connecting seat, the connecting seat driving the servo tightening shaft to move on the guide rail, and the crank being used for assembling with the springs.

[0007] The sorting device is connected to the loading robot, which uses a crank to feed the springs into the next process; the spring sorting vibratory feeder is used to disperse and sort the springs; and the conveying device is used to convey the springs and limit their movement.

[0008] Due to the aforementioned structural design, a sorting device is used to sort, sequence, and adjust the posture of the incoming springs, thereby limiting their orientation and making assembly more efficient. A replenishment tray receives the incoming springs and is connected to a spring sorting vibratory feeder. The springs are fed into the vibratory feeder for dispersion and sorting. After processing, the springs are conveyed into a conveyor for the next process. The springs processed by the vibratory feeder maintain a uniform posture, facilitating subsequent assembly.

[0009] Furthermore, in order to improve the efficiency of springs entering the spring sorting vibratory feeder, the feeding tray is provided with a notch, through which the springs enter the spring sorting vibratory feeder for sorting and arrangement; and the spring sorting vibratory feeder is provided with a dispersing mechanism, which is used to separate the springs.

[0010] Furthermore, in order to connect the spring sorting vibratory feeder with the subsequent process, the spring sorting vibratory feeder is connected to the feed end of the conveying device, and the feed end of the conveying device is equipped with a material level sensor, which is used to detect the presence or absence of springs.

[0011] Furthermore, in order to achieve precise storage and positioning of the springs, the discharge end of the conveying device is connected to the spring misalignment device, which is used to store and position the springs. The spring misalignment device includes a misalignment cylinder and a spring storage hole. A spring sensor is provided on one side of the spring storage hole. The spring sensor is used to detect whether there is a spring in the spring storage hole. The spring sensor is connected to the misalignment cylinder for signal adjustment of the position of the spring storage hole.

[0012] Furthermore, in order to accommodate the slight displacement and angle changes of the elbow during movement, the connecting seat is equipped with a floating bracket and a servo tightening shaft. The elbow is connected to the floating bracket via the servo tightening shaft, and the floating bracket is mounted on the connecting seat. The servo tightening shaft is used to tighten the spring.

[0013] Furthermore, to ensure the stability and firmness of the spring on the elbow, the elbow is connected to the servo tightening shaft via a clamp, and a wire clip is provided at one end of the elbow to fix the spring.

[0014] Furthermore, in order to apply pulse pressure to the end of the spring, the bend is an eccentric bend.

[0015] Furthermore, to avoid assembly errors, the connector is also equipped with a detector, which is used to detect whether the elbow contains a spring.

[0016] Furthermore, in order to avoid the metal particles or magnetic materials around the assembly machine from affecting the assembly accuracy, the automatic spring assembly machine is also equipped with a demagnetizer, which is used to demagnetize the bend.

[0017] Furthermore, the automatic spring assembly machine also includes a positioning device for positioning the workpiece; the positioning device includes a clamping positioner, a lifting positioner, a stopper, and a workpiece mounting base; the lifting positioner is located at the lower end of the workpiece mounting base and is used to accurately position the workpiece mounting base; the stopper is used to limit the workpiece mounting base; and the clamping positioner is used to limit the workpiece on the workpiece mounting base.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. By setting up a sorting device to sort, arrange, and adjust the posture of the fed springs, the posture of the springs is defined, making assembly more efficient. The replenishment tray is used to receive the fed springs. The replenishment tray is connected to the spring sorting vibratory feeder, which feeds the springs into the spring sorting vibratory feeder for dispersion and sorting. The springs processed by the spring sorting vibratory feeder are sent into the conveyor device for the next process. Among them, the springs processed by the spring sorting vibratory feeder have a uniform posture, which facilitates subsequent assembly.

[0020] 2. The spring sorting vibratory feeder is equipped with a dispersing mechanism to disperse the springs fed in by the feeding plate and to uniformly adjust the posture of the springs before sending them into the conveying device. This can limit the posture of the springs and facilitate subsequent steps. The spring sorting vibratory feeder is equipped with a sorting channel, through which the springs enter the conveying device in an orderly manner.

[0021] 3. The conveying device is connected to the spring misalignment device. The spring misalignment device is used to receive the springs fed by the conveying device and install the springs in the spring storage holes, waiting for the loading robot to grab the springs and assemble them with the workpieces. The spring storage holes are equipped with spring sensors. When the spring sensors detect that there are springs in the spring storage holes, the loading robot picks up the springs in the spring storage holes. This enables the automatic assembly of the spring assembly machine. Attached Figure Description

[0038] The present invention will now be described in detail with reference to the accompanying drawings.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0040] like Figure 1 - Figure 10 As shown, an automatic spring assembly machine is provided, in which springs to be assembled are sent to a sorting device 1 for sorting by manual labor or machine; wherein, a feeding tray 101 receives the sent springs, and then the springs fall into a spring sorting vibratory plate 102 for dispersion, sorting and posture limitation; the spring sorting vibratory plate 102 is connected to a conveying device 103, which continues to convey the springs to the next process position.

[0041] The output end of the conveying device 103 is connected to the spring misalignment device 4. The spring misalignment device 4 is provided with a spring storage hole 402, and the spring storage hole 402 is connected to the output end of the conveying device 103. The spring conveyed by the conveying device 103 is inserted into the spring storage hole 402, and the misalignment cylinder 401 moves the spring.

[0042] The loading robot 2 connects to the spring misalignment device 4 via the elbow 202, and the elbow 202 assembles the spring with the workpiece.

[0043] This completes the automatic assembly of springs and workpieces. The sorting device 1 disperses and restricts the posture of the springs, and the spring misalignment device 4 connects with the loading robot 2 to ensure that the springs enter the assembly process in the set posture, which can improve the efficiency and accuracy of spring assembly to a certain extent.

[0044] Example 1

[0045] like Figure 3 and Figure 6 As shown, one embodiment of this utility model is that the automatic spring assembly machine includes:

[0046] Sorting device 1 is used for preliminary sorting of springs. The sorting device 1 includes a feeding tray 101, a spring sorting vibratory feeder 102, and a conveying device 103. The feeding tray 101 is disposed above the spring sorting vibratory feeder 102. The springs enter the spring sorting vibratory feeder 102 through the feeding tray 101. The spring sorting vibratory feeder 102 is connected to the conveying device 103, which is used to convey the springs. The spring sorting vibratory feeder 102 and the conveying device 103 are used together to define the spring posture.

[0047] The feeding tray 101 is positioned above the spring sorting vibratory feeder 102, and its main function is to supply springs to the spring sorting vibratory feeder 102. The springs are fed into the vibratory feeder via the feeding tray 101. The spring sorting vibratory feeder 102 utilizes vibration principles to disperse and sort the springs. Through specific vibration frequencies and amplitudes, the vibratory feeder causes the springs to flow in an orderly manner within the feeder, thereby ensuring that the springs are neatly arranged and have a consistent posture. The conveying device 103 is connected to the spring sorting vibratory feeder 102 and is used to convey the sorted springs. The conveying device 103 not only performs a transmission function but also limits the movement of the springs, ensuring that the springs maintain a stable posture during conveying.

[0048] The loading robot 2 is used to carry a spring for positional movement. The loading robot 2 includes a guide rail 201, a crank 202, and a servo tightening shaft 220. The crank 202 is connected to the servo tightening shaft 220. The servo tightening shaft 220 is mounted on the guide rail 201 through a connecting seat 203. The connecting seat 203 drives the servo tightening shaft 220 to move on the guide rail 201. The crank 202 is used to connect to the spring.

[0049] The guide rail 201 is a three-axis guide rail, including an X-axis guide rail, a Y-axis guide rail, and a Z-axis guide rail. The elbow 202 is mounted on the Z-axis guide rail via a connecting seat 203. The Z-axis guide rail is mounted on the Y-axis guide rail, and the Y-axis guide rail is mounted on the X-axis guide rail. Thus, the elbow 202 can move in space through the combined motion of the three-axis guide rail.

[0050] Guide rail 201 provides the basic path for the movement of the loading robot 2. The robot moves along guide rail 201 in a straight line or curve to achieve precise positioning of the spring. The elbow 202 is mounted on guide rail 201 via connecting seat 203 for connection to the spring. The elbow 202 must ensure a secure connection with the spring and maintain its stability during movement. Connecting seat 203 is the connecting component between elbow 202 and guide rail 201. It can slide on guide rail 201, thereby driving elbow 202 and the spring to move.

[0051] The sorting device 1 is connected to the loading robot 2, which uses a bend 202 to feed the springs into the next process. The spring sorting vibratory plate 102 is used to disperse and sort the springs, and the conveying device 103 is used to convey the springs and limit their movement.

[0052] During the operation of the automatic spring assembly machine, the sorting device 1 first supplies springs to the spring sorting vibratory feeder 102 via the feeding tray 101. After the vibratory feeder disperses and sorts the springs, the springs are transported to the designated positions via the conveying device 103. At this time, the loading robot 2 picks up the springs from the conveying device 103 via the guide rail 201 and the elbow 202, and accurately feeds them into the next process for assembly.

[0053] Specifically, the sorting device 1 and the loading robot 2 are seamlessly connected. When the spring on the conveying device 103 reaches the designated position, the crank 202 of the loading robot 2 engages with the spring and, guided by the guide rail 201, sends it to the next process. Throughout the process, the spring's posture is strictly limited and maintained, thereby ensuring the accuracy and efficiency of assembly.

[0054] Example 2

[0055] like Figure 4 As shown, in another embodiment of the present invention, the feeding tray 101 is provided with a notch 110, and the spring enters the spring sorting vibratory tray 102 through the notch 110 for sorting and sorting; and the spring sorting vibratory tray 102 is provided with a dispersing mechanism, which is used to separate the springs.

[0056] The feeding tray 101 is surrounded by baffles. One baffle adjacent to the spring-sorting vibratory feeder 102 has a notch 110, allowing springs to enter the spring-sorting vibratory feeder 102 through the notch 110. This prevents springs from piling up and getting stuck between the feeding tray 101 and the spring-sorting vibratory feeder 102, improving the spring entry efficiency. Furthermore, the size of the notch 110 is adjustable; by adjusting its size and shape, the number of springs entering the vibratory feeder each time can be controlled. This helps maintain a uniform distribution of springs within the vibratory feeder, preventing poor sorting results caused by too many or too few springs.

[0057] The dispersing mechanism can break up stacked springs, which helps to avoid overlapping and interlacing between springs, ensuring that each spring can be arranged independently and orderly within the spring sorting vibratory plate 102. Based on the dispersing, the spring sorting vibratory plate 102 uses vibration principles to sort the springs. By adjusting the vibration frequency and amplitude, the flow speed and direction of the springs within the spring sorting vibratory plate 102 can be controlled, thereby achieving the orderly arrangement of the springs.

[0058] The workflow is as follows: Springs on the feeding tray 101 enter the spring sorting vibratory feeder 102 through the notch 110. The dispersing mechanism inside the spring sorting vibratory feeder 102 disperses and sorts the springs, arranging them in an orderly manner within the feeder 102. Subsequently, the conveying device 103 transports the sorted springs to a designated position for the loading robot 2 to grasp and assemble. This automatic spring assembly machine improves the sorting and sequencing efficiency of springs and ensures that the springs enter the assembly process in a stable posture. This helps reduce errors and rework rates during the assembly process, improving overall production efficiency and product quality.

[0059] Example 3

[0060] like Figure 4 As shown, another embodiment of the present invention is that, in order to connect the spring sorting vibratory plate 102 with the subsequent process, the spring sorting vibratory plate 102 is connected to the feeding end of the conveying device 103, and the feeding end of the conveying device 103 is provided with a material level sensor 3, which is used to detect whether there is a spring on the material level sensor 3.

[0061] To ensure an appropriate number of springs on the conveyor 103 and avoid reduced assembly efficiency or assembly errors due to too many or too few springs, a level sensor 3 is added to the feed end of the conveyor 103 in this embodiment. The level sensor 3 is a device capable of detecting the material position; it can monitor the position and number of springs on the conveyor 103 in real time. The level sensor 3 detects the presence of springs on the conveyor 103 by transmitting and receiving signals. When a spring enters the feed end of the conveyor 103, the level sensor 3 detects its presence and sends a corresponding signal. This signal can be received and processed by the control system, thereby achieving real-time monitoring and automatic control of the number of springs on the conveyor 103.

[0062] When the level sensor 3 detects that the number of springs on the conveyor 103 has reached a preset value, the control system will issue a command to pause the discharge operation of the spring sorting vibratory feeder 102 to avoid excessive accumulation of springs on the conveyor 103. At the same time, the control system will also adjust the conveying speed of the conveyor 103 according to actual needs to maintain a stable number of springs on the conveyor 103.

[0063] By setting the material level sensor 3, the number of springs on the conveying device 103 can be accurately detected and automatically controlled, avoiding the accumulation of springs and thus improving the efficiency and accuracy of assembly.

[0064] Example 4

[0065] like Figure 5As shown, another embodiment of this utility model is that, in order to achieve accurate storage and positioning of the springs, the discharge end of the conveying device 103 is connected to the spring misalignment device 4, which is used to store and position the springs; ensuring that the springs can directly and accurately enter the spring misalignment device 4 for storage and positioning after being discharged from the conveying device 103.

[0066] The spring misalignment device 4 includes a misalignment cylinder 401 and a spring storage hole 402. A spring sensor 403 is provided on one side of the spring storage hole 402. The spring sensor 403 is used to detect the specific position of the spring. The spring sensor 403 is signal-connected to the misalignment cylinder 401. The misalignment cylinder 401 is used to adjust the position of the spring storage hole 402.

[0067] The misalignment cylinder 401 is the power component of the spring misalignment device 4, responsible for driving the spring storage hole 402 to adjust its position. By controlling the extension and retraction of the misalignment cylinder 401, precise positioning of the spring storage hole 402 can be achieved, thereby ensuring that the spring can be accurately stored in the predetermined position.

[0068] The spring storage hole 402 is a storage component of the spring misalignment device 4, responsible for storing and positioning the springs. Each spring storage hole 402 is designed with a hole that matches the shape and size of the spring to ensure that the spring can be stably stored in the hole. At the same time, the spring storage hole 402 is also designed with a connecting component that connects to the misalignment cylinder 401 so that the position can be adjusted by driving the misalignment cylinder 401.

[0069] To ensure the spring is accurately stored in the spring storage hole 402, a spring sensor 403 is added to one side of the spring storage hole 402 to monitor in real time whether the spring is correctly stored in the storage hole. The spring sensor 403 is signal-connected to the misalignment cylinder 401. When the spring sensor 403 detects that the spring is correctly stored in the storage hole, it sends a signal to the misalignment cylinder 401, instructing the misalignment cylinder 401 to stop its extension and retraction. Conversely, if the spring sensor 403 detects that the spring is not correctly stored in the storage hole, it sends a signal to the misalignment cylinder 401, instructing the misalignment cylinder 401 to continue its extension and retraction until the spring is correctly stored in the storage hole. This achieves precise storage and positioning of the spring, facilitating subsequent gripping and assembly processes.

[0070] Example 5

[0071] like Figure 7As shown, in another embodiment of the present invention, the connecting seat 203 is provided with a floating bracket 210 and a servo tightening shaft 220, the elbow 202 is connected to the floating bracket 210 through the servo tightening shaft 220, and the floating bracket 210 is disposed on the connecting seat 203; the servo tightening shaft 220 is used to tighten the spring and the elbow 202.

[0072] The floating bracket 210 is mounted on the connecting seat 203 and has a certain degree of floating capability, which can adapt to the slight displacement and angular changes of the elbow 202 during movement. This helps to reduce friction and wear of the elbow 202 on the connecting seat 203, and improves the stability and accuracy of the connection.

[0073] The servo tightening shaft 220 is a high-precision, high-reliability transmission component that enables a stable connection between the elbow 202 and the spring. Through the tightening action of the servo tightening shaft 220, the spring is securely fixed to the elbow 202, preventing it from falling off or loosening during movement. When the spring needs to be tightened, the servo motor starts and drives the tightening shaft to rotate, while simultaneously moving the shaft axially to tightly connect the spring and the elbow 202. During the tightening process, the servo motor can precisely control the tightening according to preset torque and angle, ensuring tightening accuracy and stability.

[0074] During the operation of the automatic spring assembly machine, when the sorting device 1 transports the spring to the designated position, the crank 202 of the loading robot 2 moves above the spring. At this time, the servo tightening shaft 220 starts and drives the crank 202 to descend, so that the connecting part of the crank 202 contacts the spring. Then, the servo tightening shaft 220 starts to rotate and move axially, firmly fixing the spring to the crank 202.

[0075] After the spring is secured, the loading robot 2 moves along the guide rail 201 to the next process position. During the movement, the floating bracket 210 can adapt to the slight displacement and angle changes of the elbow 202, ensuring the stability and accuracy of the connection between the elbow 202 and the connecting seat 203. When the next process is reached, the elbow 202 releases the spring, completing the spring assembly task.

[0076] The stable connection and precise control between the elbow 202 and the spring can improve assembly efficiency and accuracy while reducing production and labor costs.

[0077] Example 6

[0078] like Figure 8As shown, another embodiment of this utility model is that, in order to ensure the stability and firmness of the spring on the elbow 202, the elbow 202 is connected to the servo tightening shaft 220 through the clamp 204, thereby improving the stability and accuracy of the elbow 202 during movement; a wire clip 205 is also provided at one end of the elbow 202, which is used to fix the spring.

[0079] Wire clip 205 is a flexible metal clip whose shape and size match the outer diameter of the spring. When the spring is placed on the bend 202, wire clip 205 can firmly hold the spring in place, preventing it from falling off or loosening during movement.

[0080] During the operation of the automatic spring assembly machine, when the sorting device 1 delivers the spring to the designated position, the crank 202 of the loading robot 2 moves above the spring. At this time, the servo tightening shaft 220 starts and drives the crank 202 to descend, so that the connecting part of the crank 202 contacts the spring. The servo tightening shaft 220 begins to rotate and move axially, tightly connecting the crank 202 and the spring together through the clamp 204. Simultaneously with the connection between the crank 202 and the spring, the wire clip 205 also holds the spring in place, ensuring its stability and firmness during movement. After the spring is secured, the loading robot 2 moves along the guide rail 201 to the next process position. During this movement, the servo tightening shaft 220 and the clamp 204 ensure the stability and precision of the connection between the crank 202 and the spring.

[0081] When the next process is reached, the elbow 202 will release the spring as needed to complete the spring assembly task. At this time, the wire clip 205 will also automatically release, allowing the spring to be smoothly connected to the assembly component.

[0082] The use of the sleeve 204 and the wire clip 205 enables the elbow 202 to be stably connected to the servo tightening shaft 220, thereby improving assembly efficiency.

[0083] Example 7

[0084] like Figure 8 As shown, in another embodiment of this utility model, the bend 202 is an eccentric bend 202, which can apply pulse pressure to the end of the spring to press the spring into the spring storage hole 402. The eccentricity and rotation angle of the bend 202 can be adjusted. By adjusting the eccentricity and rotation angle of the eccentric bend 202, the spring can be accurately positioned and flexibly adjusted during the assembly process, thereby improving the accuracy of spring assembly.

[0085] Example 8

[0086] like Figure 7As shown, in another embodiment of the present invention, the connecting seat 203 is further provided with a detector 206, which is used to detect whether the elbow 202 contains a spring.

[0087] The detector 206 uses non-contact sensing technology to accurately and quickly detect the spring on the elbow 202. When the elbow 202 moves near the detector 206, the detector 206 will send out a detection signal and determine whether the elbow 202 contains a spring by receiving the reflected signal or measuring specific parameters (such as electromagnetic induction, optical signals, etc.).

[0088] The detector 206 is fixed to the connector 203 and should ensure accurate detection of the spring along the moving path of the bend 202. The detector 206 has a compact structure and is equipped with a dedicated sensor interface and signal processing circuitry, capable of receiving and processing detection signals and outputting detection results.

[0089] During the movement of the elbow 202 carrying the spring, when it approaches the detector 206 on the connecting seat 203, the detector 206 will emit a detection signal. If the spring is correctly installed on the elbow 202, the detector 206 will receive the reflected signal or measure a specific parameter value, outputting the detection result as "spring present". If the spring is not installed on the elbow 202 or the spring is not installed correctly, the detector 206 will not receive the reflected signal or measure the specific parameter value, outputting the detection result as "no spring". The output detection result can be transmitted to the operator for display via an electrical signal. Based on the output result of the detector 206, the control system can achieve precise control of the loading robot 2. If the detection result is "spring present", the loading robot 2 will continue to move to the next process for assembly. If the detection result is "no spring", the control system will issue an alarm signal and stop the movement of the loading robot 2 to prevent failure of subsequent assembly processes.

[0090] By setting a detector 206 on the connector 203, the real-time monitoring and precise control of whether the elbow 202 contains a spring can be achieved, thus avoiding assembly errors.

[0091] Example 9

[0092] like Figure 9 As shown, in another embodiment of this utility model, during the use of the automatic spring assembly machine, the bend 202 may become magnetic due to contact with magnetic materials. If the bend 202 is magnetic, it may attract surrounding metal particles or magnetic materials, thereby affecting the assembly accuracy and efficiency of the spring. Furthermore, magnetism may also interfere with other electronic components in the assembly equipment. Therefore, a demagnetizer 5 is provided on the automatic spring assembly machine to demagnetize the bend 202.

[0093] The demagnetizer 5 uses electromagnetic principles to eliminate the magnetism on the elbow 202 by generating a reverse magnetic field. When the elbow 202 passes through the demagnetizer 5, the demagnetizer 5 emits a reverse magnetic field, causing the magnetism on the elbow 202 to gradually weaken and disappear. This ensures that the elbow 202 will not attract metal particles or magnetic materials during assembly, nor will it interfere with other electronic components in the assembly equipment.

[0094] During the operation of the automatic spring assembly machine, after the bend 202 completes an assembly task, it returns to its starting position along a predetermined path. At this time, the bend 202 passes through the demagnetizer 5, which emits a reverse magnetic field to demagnetize the bend 202. The demagnetization process is usually very brief, taking only a few seconds. During the demagnetization process, the magnetic field controller of the demagnetizer 5 monitors the magnetic field strength and the position of the bend 202 in real time to ensure optimal demagnetization. When the bend 202 completely leaves the magnetic field range of the demagnetizer 5, the demagnetization process ends, and the bend 202 is ready for the next assembly task.

[0095] This avoids interference from magnetism with other electronic components in the assembly equipment, thereby improving assembly accuracy and efficiency.

[0096] Example 10

[0097] like Figure 10 As shown, another embodiment of the present invention further includes a positioning device 6 for positioning the workpiece. The positioning device 6 includes a clamping positioner 601, a lifting positioner 602, a stopper 603, and a workpiece mounting base 604. The lifting positioner 602 is disposed at the lower end of the workpiece mounting base 604 and is used to accurately position the workpiece mounting base 604. The stopper 603 is used to limit the workpiece. The clamping positioner 601 is used to limit the workpiece on the workpiece mounting base 604. When the spring is placed on the mounting base, the clamping positioner 601 clamps the spring to prevent it from shifting or falling off during the assembly process.

[0098] The workpiece is positioned by the positioning device 6 to facilitate assembly with the spring. The lifting positioner 602 is used to adjust the position of the workpiece so that it matches the height of the crank 202 of the loading robot 2, so that the crank 202 can send the spring to the designated position of the workpiece. The stopper 603 is used to restrict the horizontal position of the workpiece, and the lifting positioner 602 is used to restrict the vertical position of the workpiece.

[0099] The workpiece is placed on the workpiece mounting base 604. The lifting positioner 602 adjusts the workpiece according to the preset height parameters to facilitate the installation of the spring and the workpiece. The stopper 603 is used to limit the position of the workpiece in the horizontal direction. The clamping positioner 601 is also used to limit the position of the workpiece to ensure that it will not fall off or shift during the assembly process. The loading robot 2 docks and assembles the spring and the workpiece. After the assembly is completed, the workpiece and the spring are moved by the subsequent device.

[0100] By precisely positioning the workpiece and the spring, the accuracy of assembly is improved, ensuring the stability and reliability of the assembly process.

[0101] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
