Description

Technical Field

[0001] This application relates to the field of assembly machinery and equipment, specifically to a spring feeding device. Background Technology

[0002] With the continuous updating of production and assembly technology, the requirements for assembly efficiency are also constantly increasing. In the process of product assembly, some processes require the assembly of springs. If the springs are assembled manually, the assembly efficiency is low, and after a long period of assembly, workers are prone to fatigue, which can lead to omissions in assembly and affect the product's function.

[0003] In some existing technologies, springs are automatically unloaded using a vibratory feeder. However, since the springs are output horizontally from the vibratory feeder, they cannot meet assembly requirements and still require manual intervention, resulting in low assembly efficiency. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a spring feeding device that can change the direction of the springs while automatically feeding them, so as to realize the automatic assembly of the springs and improve assembly efficiency.

[0005] A spring feeding device according to an embodiment of this application includes: a vibratory feeder, a distributing mechanism, and a picking mechanism. The vibratory feeder includes a vibratory feeder body and a conveying track. The vibratory feeder body is used to hold springs. The conveying track extends along a first direction and is connected to the vibratory feeder body. The conveying track is adapted to convey the springs. The distributing mechanism is located downstream of the conveying track. The distributing mechanism includes a rotating part. The conveying track has a discharge end. The rotating part has a picking end. The discharge end is connected to the picking end so that the springs enter the rotating part from the vibratory feeder. The rotating part can rotate the springs. The picking mechanism is located downstream of the distributing mechanism. The picking mechanism includes a picking track and a picking part. The picking part is slidably disposed on the picking track. The picking part has a picking position. The picking part is disposed at the picking position corresponding to the rotating part and is adapted to pick up the springs at the picking position.

[0006] According to the spring feeding device of this application embodiment, the spring is housed in the vibratory feeder body. Through the vibration of the vibratory feeder, the spring can be regularly moved from the vibratory feeder body to the conveying track. The conveying track is inclined downwards from the vibratory feeder body to the discharge end. On the conveying track, the spring is in an inclined state and tends to move towards the discharge end under the action of gravity. As springs are continuously conveyed out of the vibratory feeder body, the springs located on the conveying track can move towards the discharge end. When the spring moves to the discharge end, since the picking end of the rotating part of the distributing mechanism is connected to the discharge end, the spring can enter the rotating part from the picking end. After the spring enters the rotating part, the rotating part can rotate the spring, making it vertical. At this time, the picking part on the picking mechanism can move to the position corresponding to the rotating part, that is, the picking position. At the picking position, the picking part can grasp the spring in the vertical state. After the picking part grasps the spring, subsequent processes can be performed. Therefore, the spring feeding device of this application can automatically feed springs while changing the direction of the springs to achieve automatic spring assembly, resulting in higher assembly efficiency.

[0007] In some embodiments, the feeding mechanism further includes a receiving section, which is selectively connected to the rotating section to indirectly connect the discharge end to the rotating section. The receiving section includes an inlet and a first driving member. The inlet is connected to the discharge end so that the spring enters the receiving section from the vibrating plate. The first driving member is adapted to push the spring from the receiving section to the rotating section in a second direction. This allows for control of the spring feeding speed, improving the operational stability of the spring feeding device.

[0008] In some embodiments, the receiving portion further includes a receiving seat, a first constraint block, a second constraint block, and a third constraint block. The receiving seat is adapted to support the spring. The first driving member, the first constraint block, the second constraint block, and the third constraint block are all fixed to the receiving seat. The first constraint block, the second constraint block, and the third constraint block define a receiving space. The first constraint block and the second constraint block are disposed opposite to each other to define the feed inlet. The third constraint block is disposed away from the feed inlet to stop the spring in the first direction. Thus, the spring is constrained in the receiving space after entering the receiving portion from the discharge end, preventing the spring from dislodging and improving the operational stability of the spring feeding device.

[0009] Furthermore, a first sensor is provided on the third constraint block. The first sensor is adapted to detect whether the spring is located in the receiving space, and the first sensor is signal-connected to the first driving member. Thus, the first sensor can detect the spring position so that the first driving member can promptly push the spring, thereby improving the operating efficiency of the spring feeding device.

[0010] Optionally, the rotating part includes a rotating block and a rotating platform. The rotating block is disposed on the rotating platform and has a first axis, which is adapted to rotate axially about the first axis. The first axis is parallel to the second direction. The rotating block can rotate between a first position and a second position. The first driving member is adapted to push the spring from the receiving part to the rotating part when the rotating block is in the first position. The picking part is adapted to pick up the spring at the picking position when the rotating block is in the second position. Thus, by pushing the spring to the rotating part and switching the rotating part from the first position to the second position, the spring can be switched from a horizontal state to a vertical state, reducing the picking difficulty of the picking mechanism and thereby improving the operating efficiency of the spring feeding device.

[0011] Optionally, the rotating block includes a rotating disk disposed on the side of the rotating block facing the rotating platform. At least one stop block is provided on the circumferential side of the rotating disk, and at least one limiting block is correspondingly provided on the rotating platform. The stop block and the limiting block can abut against each other when the rotating block is in a first position and / or a second position. Thus, by limiting the rotation angle of the rotating disk through the stop block and the limiting block, the rotation angle of the rotating block can be restricted, preventing the material-grabbing mechanism from failing to pick up materials normally due to excessively large or small rotation angles, thereby improving the operational stability of the spring feeding device.

[0012] Optionally, the rotating block further includes a rotating receiving component connected to the rotating disk. The rotating receiving component includes a side plate, a bottom plate, and a feeding trough. One end of the side plate is connected to the bottom plate, and the other end of the side plate forms a material-grabbing end. Thus, the feeding trough can constrain the position of the spring, reducing the positioning accuracy of the material-grabbing mechanism when grasping the spring and improving the operating efficiency of the spring feeding device.

[0013] In some embodiments, the material distribution mechanism further includes a position detection component, which includes a sensor mounting bracket, a second sensor, and a third sensor. The second and third sensors are fixed to the sensor mounting bracket, and are respectively located on both sides of the rotating receiving member in the first direction. Thus, the second and third sensors can detect the position of the side plate, thereby determining whether the rotating block is in a first or second position, facilitating subsequent processes and improving the operating efficiency of the spring feeding device.

[0014] Optionally, one of the second and third sensors is configured as an infrared transmitter, and the other is configured as an infrared receiver, with corresponding clearance holes formed on the base plate. This allows for accurate determination of the rotating block's position, facilitating subsequent processes and improving the operating efficiency of the spring feeding device.

[0015] In some embodiments, the dispensing mechanism further includes a baffle fixed to the first constraint block, the baffle being adapted to block the material-taking end when the rotating block is in the first position. Thus, the baffle can block the opening of the material-taking end when the rotating block is in the first position, thereby preventing the spring from dislodging from the discharge trough and improving the operational stability of the spring feeding device.

[0016] In some embodiments, the spring feeding device further includes a detection mechanism fixed to the picking mechanism. The picking mechanism is adapted to pick up the spring at the picking position, move the spring to a position corresponding to the product, and assemble the spring onto the product. The detection mechanism is adapted to inspect the product. Thus, the state of the spring can be detected after it has been assembled onto the product by the picking mechanism, allowing for the timely removal of defective springs and improving the product pass rate.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0046] Reference will be made below to Figures 1-10 describe a spring feeding device 100 according to an embodiment of the present application.

[0047] As Figures 1-3 shown, a spring feeding device 100 according to an embodiment of the present application includes: a vibrating disk 10, a material distributing mechanism 20 and a material taking mechanism 30.

[0048] Among them, the vibrating disk 10 includes a vibrating disk body 11 and a conveying track 12. The vibrating disk body 11 is used to hold the springs 200. The conveying track 12 extends in the first direction and is connected to the vibrating disk body 11. The conveying track 12 is adapted to convey the springs 200. The material distribution mechanism 20 is arranged downstream of the conveying track 12. The material distribution mechanism 20 includes a rotating part 22. The conveying track 12 has a discharge end 121. The rotating part 22 has a material taking end 223. The discharge end 121 is connected to the material taking end 223, so that the springs 200 enter the rotating part 22 from the vibrating disk 10. The rotating part 22 can rotate the springs 200. The material taking mechanism 30 is located downstream of the material distribution mechanism 20. The material taking mechanism 30 includes a material taking track 31 and a material taking part 32. The material taking part 32 is slidably arranged on the material taking track 31. The material taking part 32 has a material taking position. The material taking part 32 is correspondingly arranged with the rotating part 22 at the material taking position and is adapted to grasp the springs 200 at the material taking position.

[0049] Specifically, the springs 200 are placed in the vibrating disk body 11. Through the vibration of the vibrating disk 10, the springs 200 can be regularly moved from the vibrating disk body 11 onto the conveying track 12. The conveying track 12 is inclined downward from the vibrating disk body 11 to the discharge end 121. On the conveying track 12, the springs 200 are in an inclined state. Under the action of gravity, the springs 200 have a tendency to move towards the discharge end 121. As the subsequent springs 200 are continuously conveyed out of the vibrating disk body 11, the springs 200 on the conveying track 12 can move towards the discharge end 121. When the springs 200 move to the discharge end 121, due to the connection between the material taking end 223 of the rotating part 22 of the material distribution mechanism 20 and the discharge end 121, the springs 200 can enter the rotating part 22 from the material taking end 223. After the springs 200 enter the rotating part 22, the rotating part 22 can rotate the springs 200 to make the springs 200 rotate to a vertical state. At this time, the material taking part 32 on the material taking mechanism 30 can move to a position corresponding to the rotating part 22, that is, the material taking position. At the material taking position, the material taking part 32 can grasp the springs 200 in the vertical state. After the material taking part 32 grasps the springs 200, subsequent processes can be carried out.

[0050] It is understandable that when the conveyor track 12 is inclined, the rotating part 22 can also be inclined, and correspondingly, the picking mechanism 30 can also be inclined. When the spring 200 enters the picking end 223 of the rotating part 22 at an inclined position from the discharge end 121, the spring 200 is in an inclined state within the rotating part 22. Then, the rotating part 22 can rotate the spring 200, and then the picking part 32 moves to the picking position and picks up the rotated spring 200. It should be noted that the state of the spring 200 in the picking position can be non-vertical, as long as the picking part 32 can smoothly pick up the spring 200. It should also be noted that there are no specific restrictions on the angles of the vibratory feeder 10, the rotating part 22, and the picking mechanism 30, which can be adjusted according to actual needs.

[0051] According to the spring feeding device 100 of this application embodiment, the direction of the spring 200 can be changed while automatically feeding the spring 200, which facilitates the automatic assembly of the spring 200 and improves the assembly efficiency.

[0052] Optionally, the conveying track 12 is provided with a track groove 122, within which the spring 200 can slide. When the spring 200 is output from the vibrating plate body 11 to the conveying track 12, it can enter the track groove 122. By sliding within the track groove 122, the running trajectory of the spring 200 can be constrained, ensuring that the spring 200 accurately enters the feeding end 223 from the discharge end 121, thereby improving the operating efficiency of the spring feeding device 100.

[0053] Alternatively, a first cover plate 123 is provided on the track groove 122, and the first cover plate 123 is detachably connected to the conveying track 12. By providing the first cover plate 123 on the track groove 122, the spring 200 can be prevented from coming out of the opening of the track groove 122, thereby limiting the spring 200 and improving the operational stability of the spring feeding device 100.

[0054] It should be noted that there are no specific restrictions on the connection method between the first cover plate 123 and the conveying track 12. For example, the first cover plate 123 can be connected to the conveying track 12 by bolts, or the first cover plate 123 can be attracted to the conveying track 12 by magnetic force. The first cover plate 123 is set to be detachable, so that problems can be checked when the vibratory feeder 10 malfunctions or needs to be repaired, reducing the maintenance difficulty of the spring feeding device 100.

[0055] It is understandable that the material distribution mechanism 20 is located downstream of the conveying track 12 and the material picking mechanism 30 is located downstream of the material distribution mechanism 20. There are no specific restrictions on the positions of the material distribution mechanism 20 and the material picking mechanism 30. The upstream and downstream only restrict the running order of the spring 200 in different mechanisms. The material distribution mechanism 20 can be located in any direction of the conveying track 12. Similarly, the material picking mechanism 30 can also be located in any direction of the material distribution mechanism 20.

[0056] In some embodiments, the dispensing mechanism 20 further includes a receiving section 21, which is optionally connected to the rotating section 22. In this case, the discharge end 121 can be indirectly connected to the rotating section 22 through the receiving section 21. The receiving section 21 includes an inlet 211 and a first driving member 212. The inlet 211 is connected to the discharge end 121 so that the spring 200 enters the receiving section 21 from the vibrating plate 10. The first driving member 212 is adapted to push the spring 200 from the receiving section 21 to the rotating section 22 in a second direction. The inlet 211 of the receiving section 21 is connected to the discharge end 121. The spring 200 can enter the receiving section 21 through the inlet 211, and then the first driving member 212 can push the spring 200 from the receiving section 21 to the rotating section 22 in a second direction. The first driving member 212 can adjust the speed at which it pushes the spring 200 according to the gripping speed of the spring 200 by the picking mechanism 30. Therefore, the feeding speed of the spring 200 can be controlled, thereby improving the operational stability of the spring feeding device 100.

[0057] like Figure 3 , Figure 4 As shown, in some embodiments, the receiving part 21 further includes a receiving seat 213, a first constraint block 214, a second constraint block 215, and a third constraint block 216. The receiving seat 213 is adapted to support the spring 200. The first driving member 212, the first constraint block 214, the second constraint block 215, and the third constraint block 216 are all fixed to the receiving seat 213. The first constraint block 214, the second constraint block 215, and the third constraint block 216 define a receiving space. The first constraint block 214 and the second constraint block 215 are arranged opposite to each other to define the feed inlet 211. The third constraint block 216 is arranged away from the feed inlet 211 to stop the spring 200 in a first direction.

[0058] Specifically, the receiving seat 213 supports the spring 200, and the first constraint block 214, the second constraint block 215, and the third constraint block 216 limit the movement of the spring 200 around its periphery. When the spring 200 moves from the conveying track 12 to the receiving part 21, it can enter the receiving space through the feed port 211 between the first constraint block 214 and the second constraint block 215. The first constraint block 214 and the second constraint block 215 guide the spring 200. The receiving seat 213 supports the spring 200 at this time. When the spring 200 enters the receiving space, it tends to continue moving forward in the first direction. At this time, the third constraint block 216 stops the spring 200, restricting the spring 200 within the receiving space. Then, the first driving member 212 moves the spring 200 from the receiving space to the rotating part 22.

[0059] Therefore, after the spring 200 enters the receiving part 21 from the discharge end 121, it is constrained in the receiving space, preventing the spring 200 from coming out and improving the operational stability of the spring feeding device 100.

[0060] Optionally, a second cover plate 218 is provided on the top of the first constraint block 214 and the second constraint block 215. By providing the second cover plate 218 on the top of the first constraint block 214 and the second constraint block 215, the spring 200 can be limited, preventing the spring 200 from popping out of the receiving part 21 when it enters the feed port 211 from the conveying track 12, thereby improving the operational stability of the spring feeding device 100.

[0061] Furthermore, a first sensor 217 is provided on the third constraint block 216. The first sensor 217 is adapted to detect whether the spring 200 is located in the receiving space. The first sensor 217 is signal-connected to the first drive member 212. When the first sensor 217 detects that the spring 200 is in the receiving space, it can send a signal to the first drive member 212, causing the first drive member 212 to push the spring 200 from the receiving space to the rotating part 22. Thus, the first sensor 217 can detect the position of the spring 200 so that the first drive member 212 can push the spring 200 in a timely manner, thereby improving the operating efficiency of the spring feeding device 100.

[0062] It should be noted that the type of the first sensor 217 is not specifically limited here. The first sensor 217 can be a contact sensor or a distance sensor, as long as the first sensor 217 can detect the position of the spring 200 within the receiving space. It can be selected according to actual needs. It should also be noted that the spring 200 can slide obliquely along the conveying track 12 into the receiving part 21. Since the receiving part 21 horizontally supports the spring 200, the spring 200 changes from an oblique state to a horizontal state before being pushed into the rotating part 22. In other embodiments, the receiving part 21 can also keep the spring 200 in a non-horizontal state, as long as it corresponds to the inlet of the rotating part 22 and can smoothly move the spring 200 into the rotating part 22.

[0063] like Figures 4-6 As shown, optionally, the rotating part 22 includes a rotating block 221 and a rotating table 222. The rotating block 221 is disposed on the rotating table 222. The rotating block 221 has a first axis and is adapted to rotate axially about the first axis. The first axis is parallel to a second direction. The rotating block 221 can rotate between a first position and a second position. The first driving member 212 is adapted to push the spring 200 from the receiving part 21 to the rotating part 22 when the rotating block 221 is in the first position. The picking part 32 is adapted to pick up the spring 200 at the picking position when the rotating block 221 is in the second position.

[0064] Specifically, the rotating block 221 is mounted on the rotating table 222. When the rotating block 221 rotates axially, it can rotate between a first position and a second position. When the rotating block 221 is in the first position, the rotating part 22 is connected to the receiving part 21. The first driving member 212 can push the spring 200 from the receiving space to the rotating block 221. Then the rotating block 221 can rotate axially and switch from the first position to the second position. At this time, the spring 200 can rotate from a horizontal state to a vertical state. When the rotating block 221 is in the second position, the picking part 32 can move to the picking position to pick up the spring 200.

[0065] Therefore, by pushing the spring 200 to the rotating part 22 and switching the rotating part 22 from the first position to the second position, the spring 200 can be switched from a horizontal state to a vertical state, reducing the difficulty of material picking by the material picking mechanism 30 and thus improving the operating efficiency of the spring feeding device 100.

[0066] like Figures 4-7As shown, optionally, the rotating block 221 includes a rotating disk 2211, which is disposed on the side of the rotating block 221 facing the rotating table 222. At least one stop block 2212 is provided on the circumferential side of the rotating disk 2211, and at least one limiting block 2221 is correspondingly provided on the rotating table 222. The stop block 2212 and the limiting block 2221 can stop the rotating block 221 when it is in a first position and / or a second position. Thus, by limiting the rotation angle of the rotating disk 2211 through the stop block 2212 and the limiting block 2221, the rotation angle of the rotating block 2211 can be restricted, preventing the rotating block 221 from rotating too large or too small, which would cause the material handling mechanism 30 to fail to handle material normally, thereby improving the operational stability of the spring feeding device 100.

[0067] It is understandable that the stop block 2212 and the limit block 2221 can abut against each other in different positions. For example, the stop block 2212 and the limit block 2221 can abut against each other when the rotating block 221 is in the first position, or the stop block 2212 and the limit block 2221 can abut against each other when the rotating block 221 is in the second position. Alternatively, multiple stop blocks 2212 and limit blocks 2221 can be provided, and they can abut against each other when the rotating block 221 is in the first position and the second position, so that the rotation can be performed according to actual needs.

[0068] Optionally, the rotating part 22 further includes a second driving member 224, which is disposed between the rotating disk 2211 and the rotating table 222 and is adapted to drive the rotating disk 2211 to rotate axially along the first axis. The second driving member 224 can drive the rotating block 221 to rotate, thereby realizing the automatic switching of the rotating block 221 between the first position and the second position, and thus improving the operating efficiency of the spring feeding device 100.

[0069] like Figure 6 , Figures 8-9 As shown, optionally, the rotating block 221 further includes a rotating receiving member 2213, which is connected to the rotating disk 2211. The rotating receiving member 2213 includes a side plate 2213a, a bottom plate 2213b, and a feeding trough 2213c. One end of the side plate 2213a is connected to the bottom plate 2213b, and the other end of the side plate 2213a forms a feeding end 223.

[0070] Specifically, when the first driving member 212 pushes the spring 200 from the receiving part 21 to the rotating part 22, the spring 200 can be moved from the receiving space to the discharge trough 2213c. After the spring 200 enters the discharge trough 2213c, the side plate 2213a and the bottom plate 2213b can constrain the spring 200. When the rotating block 221 switches from the first position to the second position, the bottom plate 2213b located at one end of the side plate 2213a can support the spring 200 to prevent it from falling. The picking part 32 can grab the spring 200 from the picking end 223.

[0071] Therefore, the side plate 2213a and the bottom plate 2213b can constrain the position of the spring 200, reduce the positioning accuracy of the material handling mechanism 30 when it grabs the spring 200, and improve the operating efficiency of the spring feeding device 100.

[0072] like Figure 10 As shown, in some embodiments, the material distribution mechanism 20 further includes a position detection component 23, which includes a sensor mounting bracket 231, a second sensor 232, and a third sensor 233. The second sensor 232 and the third sensor 233 are fixed to the sensor mounting bracket 231, and are respectively located on both sides of the rotating receiving member 2213 in the first direction. Thus, the second sensor 232 and the third sensor 233 can detect the position of the side plate 2213a, thereby determining whether the rotating block 221 is in the first or second position, facilitating subsequent processes and improving the operating efficiency of the spring feeding device 100.

[0073] It should be noted that there is no specific limitation on the types of the second sensor 232 and the third sensor 233. Optionally, one of the second sensor 232 and the third sensor 233 may be configured as an infrared transmitter, and the other may be configured as an infrared receiver. The base plate 2213b has a corresponding clearance hole 2213d. Specifically, the infrared transmitter can emit infrared rays to the infrared receiver. Since the clearance hole 2213d is provided at the corresponding position of the base plate 2213b, the infrared rays can pass through smoothly. When the infrared receiver can receive the signal from the infrared transmitter, it indicates that the rotating block 221 is in the first position. When the infrared receiver cannot receive the signal from the infrared transmitter, it indicates that the rotating block 221 is in the second position, and the signal from the infrared transmitter is blocked by the side plate 2213a and cannot reach the infrared receiver.

[0074] In some embodiments, the second sensor 232 and the third sensor 233 can be selected as distance sensors. In this case, the position of the rotating block 221 can be determined by detecting the distance between the sensor and the rotating block 221. Only one of the second sensor 232 and the third sensor 233 needs to be selected. The position detection of the rotating block 221 can be achieved by setting one distance sensor, and it is not required to set two sensors. Alternatively, the second sensor 232 and the third sensor 233 can be selected as contact sensors. In this case, the position of the rotating block 221 can be determined by contacting the second sensor 232 and the third sensor 233 when the rotating block 221 rotates to the first position or the second position. The selection can be made according to actual needs. In this case, only one of the second sensor 232 and the third sensor 233 needs to be selected, and it is not required to set two sensors.

[0075] Therefore, the position of the rotating block 221 can be accurately determined, which facilitates subsequent processes and improves the operating efficiency of the spring feeding device 100.

[0076] like Figure 10 As shown, in some embodiments, the dispensing mechanism 20 further includes a baffle 24, which is fixed to the first constraint block 214. The baffle 24 is adapted to block the material-taking end 223 when the rotating block 221 is in the first position. Thus, the baffle 24 can block the opening of the material-taking end 223 when the rotating block 221 is in the first position, thereby preventing the spring 200 from discharging from the discharge trough 2213c through the material-taking end 223, thereby improving the operational stability of the spring feeding device 100.

[0077] Optionally, when the second sensor 232 and the third sensor 233 are respectively an infrared transmitter and an infrared receiver, the baffle 24 is provided with a clearance notch 241 at the corresponding position. Thus, the clearance notch 241 at the corresponding position of the baffle 24 allows infrared light to pass smoothly. When the infrared receiver can receive the signal from the infrared transmitter, it indicates that the rotating block 221 is in the first position; when the infrared receiver cannot receive the signal from the infrared transmitter, it indicates that the rotating block 221 is in the second position.

[0078] like Figure 1 As shown, in some embodiments, the spring feeding device 100 further includes a detection mechanism 40, which is fixed to the picking mechanism 30. The picking mechanism 30 is adapted to pick up the spring 200 at the picking position, drive the spring 200 to the position corresponding to the product, and assemble the spring 200 onto the product. The detection mechanism 40 is adapted to detect the product. Therefore, the state of the spring 200 can be detected after the picking device assembles the spring 200 onto the product, allowing for the timely removal of unqualified springs 200 and improving the product qualification rate.

[0079] Optionally, the detection mechanism 40 is a pressure sensor. By setting a pressure sensor, the pressure value of the spring 200 can be detected after the spring 200 is assembled onto the product. If an abnormal pressure value of the spring 200 is detected, the spring 200 can be removed from the product and reassembled in a timely manner, thereby improving the product qualification rate.

[0080] It is understandable that when the detection mechanism 40 detects an abnormal pressure value of spring 200, there could be various reasons. For example, spring 200 might have fallen off during the operation of the spring feeding device 100, or spring 200 might not have been assembled during the assembly of the material handling device. In this case, the detection mechanism cannot detect a pressure value, indicating that spring 200 is missing and needs to be reassembled. Another possibility is that spring 200 did not meet design requirements at the factory, with a pressure value that is too high or too low. When the detection mechanism 40 detects an abnormal pressure value, it indicates that spring 200 needs to be replaced.

[0081] Understandably, before the spring 200 on the product is tested by the testing mechanism 40, the product with the spring 200 installed can be manually moved to the testing mechanism 40, or the product with the spring 200 installed can be moved to the testing mechanism 40 by a conveying device, which can be set according to actual needs.

[0082] In some embodiments, the picking mechanism 30 is provided with a plurality of picking parts 32, which can sequentially pick up springs 200 at picking positions. When the picking mechanism 30 is provided with a plurality of picking parts 32, each picking part 32 can move synchronously along the picking track 31 and sequentially pick up springs 200 at picking positions. After all the picking parts 32 have picked up springs 200, they can move synchronously above the product to install springs 200 on multiple products respectively, or to install multiple springs 200 at different positions on a single product. This improves the assembly efficiency of the spring feeding device 100.

[0083] It should be noted that in the embodiments provided by the present invention (such as...) Figures 2 to 4 The discharge end 121 is connected to the rotating part 22 via the receiving part 21. That is, after the spring 200 slides out of the discharge end 121, it first enters the receiving part 21 and then moves from the receiving part 21 to the rotating part 22. However, in other embodiments, the receiving part 21 may not be necessary, and the spring 200 can directly enter the rotating part 22 after sliding out of the discharge end 121. For example, one opening of the rotating receiving member 2213 of the rotating part 22 can be directly aligned with the discharge end 121, so that the spring 200 can directly enter the discharge groove 2213c of the rotating part 22 after sliding out of the discharge end 121. It should be noted that in the embodiments provided by the present invention (such as...), Figures 1 to 2 The material picking mechanism 30 extends along the second direction. However, in other embodiments, the material picking mechanism 30 may extend straight or curved along other directions, as long as it can reach the preset material picking position to pick up the spring 200 and assemble it onto the product. The intermediate movement trajectory and the arrangement direction of the material picking mechanism 30 are not limited.

[0084] It should be noted that the first driving member 212 of the receiving part 21 is not necessarily required to push the spring 200 in the second direction. The direction of the pushing force of the first driving member 212 and the direction of movement of the spring 200 depend on the position of the first driving member 212, the position of the rotating part 22, and the position of the opening on the rotating block 221 into which the spring 200 moves. As long as the spring 200 can be pushed to the rotating part 22, it is acceptable.
