[0002] During the workpiece processing, some workpieces require the installation of steel balls. For example, steel balls need to be installed at the ends of some rod-shaped workpieces. In order to ensure that the steel balls can rotate inside the workpiece, a mounting hole is usually machined into the workpiece. Then, a spring is installed in the mounting hole, and the steel ball is installed on the spring. Finally, a pressing mechanism is used to process and press the workpiece to confine and press the steel ball into the mounting hole of the workpiece.

[0099] It should be noted that, where there is no conflict, the claims and features described in this application can be combined with each other. The application will now be described in detail with reference to the accompanying drawings.

[0100] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0101] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these applications do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary applications may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0102] See Figures 1 to 6 , Figure 17 , Figure 24 As shown, according to an embodiment of this application, a steel ball pressing device is provided for pressing a spring 70 and a steel ball 60 onto a rod 10. Specifically, the rod 10 in this embodiment is a straight rod-shaped structure, which may be, for example, a segmented rod structure, and the rod 10 has various lengths. The rod 10 includes a main body 11, and a square column head 12 is provided at the end of the main body 11. A mounting hole 121 is provided on one side of the square column head 12, and the depth direction of the mounting hole 121 is perpendicular to the length direction of the main body 11. In actual pressing, the steel ball 60 is pressed into the mounting hole 121.

[0103] The steel ball pressing equipment in this embodiment includes a base 80, a rod rotation and orientation device 20, a rod positioning and detection device 30, a spring delivery device 40, a steel ball delivery device 50, a transfer device 90, and a steel ball pressing device 100.

[0104] The rod rotation and orientation device 20, the rod positioning and detection device 30, the spring delivery device 40, the steel ball delivery device 50, and the steel ball pressing device 100 are arranged sequentially along the same straight line direction of the machine base 80. In actual operation, the rod rotation and orientation device 20 is used to rotate and orient the rod 10, so that the mounting hole 121 on the rod 10 faces upward. The transfer device 90 includes a first robotic arm 91, which is used to move the rod 10 after being rotated and oriented by the rod rotation and orientation device 20 to the rod positioning and detection device 30. Through the action of the rod positioning and detection device 30, not only can the rod 10 be positioned, but it is also convenient to select out the rods 10 that do not meet the requirements, which is more suitable for the subsequent process of delivery of springs 70 and steel balls 60. After the rod positioning and detection device 30 completes the positioning and detection of the rod 10, the transfer device 90 moves the rod 10 to the spring dispensing device 40, which then dispenses the spring 70 into the mounting hole 121. Next, the transfer device 90 moves the rod 10 to the steel ball dispensing device 50, which facilitates the dispensing of the steel ball 60 into the mounting hole 121 containing the spring 70. Finally, the transfer device 90 moves the rod 10, containing the spring 70 and steel ball 60, to the steel ball pressing device 100. The steel ball pressing device 100 presses the rod 10, thus fixing the steel ball 60 in place within the mounting hole 121, preventing it from falling out.

[0105] See Figures 4 to 10 As shown, the rod rotation orientation device 20 in this embodiment includes a base 21 and a rotation orientation component 22.

[0106] The base 21 is equipped with a first conveyor belt 211, on which multiple first fixtures 212 are fixedly mounted. These fixtures 212 are arranged sequentially along the conveying direction of the first conveyor belt 211. Each fixture 212 supports the rod material 10, and the length direction of the rod material 10 on the fixture 212 is perpendicular to the conveying direction of the first conveyor belt 211. A rotary orientation assembly 22 is mounted on the base 21 and located on the side of the first conveyor belt 211. The rotary orientation assembly 22 includes a rotary drive component 221 and a rotary connection component 222. The rotary connection component 222 is driven by the rotary drive component 221 and connected to the square column head 12 under the drive of the rotary drive component 221, thereby causing the square column head 12 to rotate, ultimately causing the mounting hole 121 to face upwards.

[0107] In actual operation, multiple rods 10 are placed one-to-one on the first fixture 212. When the first conveyor belt 211 moves, it can transport the first fixture 212 and the rods 10 placed on it forward. When the rods 10 are transported to the side of the rotary orientation component 22, the rotary drive component 221 of the rotary orientation component 22 can drive the rotary connecting component 222 to connect with the square column head 12 of the rod 10, and can simultaneously drive the square column head 12 to rotate, thereby rotating the mounting hole 121 to face upwards, making it easier for the steel ball to be placed in the mounting hole 121 in subsequent processes. That is to say, the rod rotation orientation device 20 in this embodiment assists in the orientation of the rods 10, improves the automation level of steel ball pressing, reduces manual labor, and improves the efficiency of steel ball pressing.

[0108] Furthermore, in this embodiment, the base 21 is a support frame on which the first conveyor belt 211 is provided. In actual operation, the first conveyor belt 211 is driven by a drive motor and other structures. When the drive motor drives the first conveyor belt 211 to move, it can drive the multiple first fixtures 212 to move, thereby driving the rod material 10 installed on the first fixture 212 to be transported forward. The structure is simple and easy to implement.

[0109] See Figures 5 to 11 As shown, the rotary drive component 221 in this embodiment includes a positioning frame 2211, a moving frame 2212, a first drive component 2213, and a second drive component 2214.

[0110] The positioning frame 2211 is mounted on the base 21 and located on the side of the first conveyor belt 211; the movable frame 2212 is movably mounted on the positioning frame 2211, and the rotating connecting component 222 is rotatably mounted on the movable frame 2212; the first driving member 2213 is disposed on the positioning frame 2211 to drive the movable frame 2212 to reciprocate along a transmission direction perpendicular to the first conveyor belt 211; and the second driving member 2214 is disposed on the movable frame 2212 and connected to the rotating connecting component 222 to drive the rotating connecting component 222 to rotate.

[0111] Through the function of the positioning frame 2211, the movable frame 2212, the first driving member 2213, and the second driving member 2214 can be supported and installed. In actual operation, the first driving member 2213 can drive the movable frame 2212 to reciprocate along the direction of approaching or moving away from the first conveyor belt 211. When the first driving member 2213 drives the movable frame 2212 to move closer to the first conveyor belt 211, the second driving member 2214 can drive the rotating connecting component 222 located on the movable frame 2212 to rotate and connect with the end of the rod 10. At the same time, when the second driving member 2214 drives the rotating connecting component 222 to rotate, the mounting hole 121 on the rod 10 can be rotated to the positive orientation. The structure is simple and easy to implement.

[0112] Optionally, the first driving component 2213 in this application may be a combination of a driving cylinder, a driving electric cylinder, or a driving motor and a transmission mechanism. The first driving component 2213 may be a structure such as a driving motor. Any other modifications under the concept of this application are within the protection scope of this application.

[0113] Furthermore, a slider (not shown in the figure) is provided on one of the positioning frame 2211 and the moving frame 2212, and a slide rail (not shown in the figure) adapted to the slider is provided on the other. That is to say, when the slider is set on the positioning frame 2211, the slide rail is set on the moving frame 2212; when the slider is set on the moving frame 2212, the slide rail is set on the positioning frame 2211. The length direction of the slide rail is perpendicular to the conveying direction of the first conveyor belt 211. When the first driving member 2213 drives the moving frame 2212 to move, the action of the cooperating slide rail and slider can provide guidance for the moving frame 2212, making it more suitable for the moving frame 2212 to slide on the positioning frame 2211.

[0114] Furthermore, in this embodiment, the positioning frame 2211 is provided with a stop block 22111 and an elastic element 22112. The stop block 22111 is slidably disposed on the side of the movable frame 2212 away from the first conveyor belt 211. In actual installation, the first driving member 2213 is driven to connect with the stop block 22111, and the elastic element 22112 abuts against the stop block 22111 and the movable frame 2212. When the first driving member 2213 and the stop block 22111 move, they can push the movable frame 2212 to move in a direction closer to the first conveyor belt 211. During this process, the elastic element 22112 provides a certain buffer for the movable frame 2212, making it easier to connect the rotating connecting component 222 and the rod 10.

[0115] Optionally, the elastic element 22112 in this embodiment can be a spring or an elastic sleeve, etc. To install and limit the elastic element 22112, the movable frame 2212 in this embodiment can also be provided with limiting posts or limiting holes. During actual installation, the end of the elastic element 22112 can be installed in the limiting hole or sleeved on the limiting post, resulting in a simple structure and good stability. For example, to provide effective support and cushioning for the movable frame 2212, multiple elastic elements 22112 can be provided, such as two, three, or more. These multiple elastic elements 22112 are evenly spaced between the movable frame 2212 and the stop block 22111.

[0116] See Figures 5 to 11 As shown, the rotating connecting component 222 in this embodiment includes a rotating connecting rod 2221. The length direction of the rotating connecting rod 2221 is perpendicular to the conveying direction of the first conveyor belt 211. The end of the rotating connecting rod 2221 near the first conveyor belt 211 is provided with a docking hole 2222 that is adapted to the square column head 12. With this configuration, when the first driving member 2213 drives the moving frame 2212 to move closer to the first conveyor belt 211, it can drive the rotating connecting rod 2221 to move closer to the first fixture 212. During this process, the second driving member 2214 will drive the rotating connecting rod 2221 to rotate. That is to say, the rotating connecting rod 2221 rotates while moving closer to the first conveyor belt 211. When the docking hole 2222 at the end of the rotating connecting rod 2221 is opposite to the square column head 12 and continues to move closer to the rod material 10, the docking of the rotating connecting rod 2221 and the rod material 10 can be achieved. After that, by driving the rotating connecting rod 2221 to rotate through the second driving member 2214, the rod material 10 can be rotated, thereby rotating the mounting hole 121 to the positive orientation.

[0117] Specifically, after the rod 10 is placed on the first fixture 212, the position of the square column head 12 on the rod 10 is arbitrary. Only after the first driving member 2213 pushes the moving frame 2212 to move a predetermined distance closer to the first conveyor belt 211 can it be proven that the rotating connecting rod 2221 and the square column head 12 on the rod 10 are connected. For this purpose, the rod rotation orientation device 20 in this embodiment is provided with a first detection element 23, which is set on the positioning frame 2211 to trigger a first detection signal when the moving frame 2212 moves to the predetermined position. Optionally, the first detection element 23 in this embodiment can be a proximity switch or a displacement sensor. When the first driving member 2213 pushes the moving frame 2212 to a predetermined position, it indicates that the moving frame 2212 has moved a predetermined stroke. At this time, the first detection element 23 triggers the first detection signal, indicating that the rotating connecting rod 2221 has been connected to the square column head 12 on the rod material 10. The controller on the rod material rotation orientation device 20 can be used to control the first driving member 2213 to stop working.

[0118] After the docking hole 2222 on the rotating connecting rod 2221 is aligned with the square column head 12 on the rod 10, the second driving member 2214 can drive the rotating connecting rod 2221 to rotate, thereby rotating the mounting hole 121 on the rod 10 to the correct orientation. During actual rotation, the position of the mounting hole 121 on the rod 10 is uncertain. To detect the orientation of the mounting hole 121 and improve the control accuracy and working efficiency of the rod rotation orientation device 20, in this embodiment, the docking hole 2222 is set as a square hole, and four detection holes 2223 are provided on the surface of the rotating connecting rod 2221. These four detection holes 2223 correspond one-to-one with the four sides of the square hole, and the detection holes 2223 communicate with the square hole. Correspondingly, the rotation orientation assembly 22 also includes a detection component 223, which is set on the moving frame 2212 to detect the orientation of the mounting hole 121 through the detection holes 2223 during the rotation of the rotating connecting rod 2221.

[0119] Specifically, the detection component 223 includes a laser displacement sensor. During actual installation, the laser displacement sensor is suspended and supported at the top of the rotating connecting rod 2221 by a support rod 224. When the second driving component 2214 drives the rotating connecting rod 2221 to rotate, the laser displacement sensor can pass through the detection hole 2223 for detection. When the laser displacement sensor emits a detection signal downward, the displacement of the side facing the mounting hole 121 among the four detection holes 2223 is different from the displacement of the other sides. That is to say, when the detection hole 2223 is facing the mounting hole 121, the displacement signal excited by the laser displacement sensor is different from the signal excited at the other detection holes 2223. The orientation of the mounting hole 121 can be determined by the signal emitted at this time, and thus it can be determined whether the mounting hole 121 has rotated to the positive orientation.

[0120] To simplify the control process and improve the accuracy of the rod rotation and orientation device 20 in this embodiment, the rod rotation and orientation device 20 further includes a second detection element 24. This second detection element 24 is disposed on the movable frame 2212 to detect whether the second driving member 2214 has been reset. In actual operation, when the first detection element 23 is triggered and emits a first signal, the controller on the rod rotation and orientation device 20 can control the second driving member 2214, causing it to reset. During this process, the second detection element 24 can detect the second driving member 2214, thereby determining whether it has been reset to the correct position. Optionally, the second detection element 24 can be a proximity switch, angle sensor, or other structures. Any other modifications within the scope of this application are within the protection scope of this application.

[0121] Furthermore, the rod rotation and orientation device 20 in this embodiment also includes a pressing assembly 25, which includes a support frame 251, a pressing drive member 252, and a pressing plate 253. The support frame 251 is supported on the first conveyor belt 211 and opposite to the rotation and orientation assembly 22, meaning the support frame 251 and the rotation and orientation assembly 22 are located at the same position along the length of the first conveyor belt 211. The pressing drive member 252 is disposed on the support frame 251. The pressing plate 253 is connected to the pressing drive member 252 and reciprocates along the height direction of the support frame 251 under the drive of the pressing drive member 252.

[0122] The pressing component 25 is positioned above the first conveyor belt 211 and can press down and limit the rod 10 placed on the first fixture 212, preventing the rod 10 from tilting up during the rotation process of docking with the rotating connecting rod 2221. In actual operation, the pressing drive component 252 can drive the pressing plate 253 to rise and fall. When the pressing drive component 252 drives the pressing plate 253 to move onto the first fixture 212, it can limit the rod 10 on the first fixture 212, preventing the rod 10 from falling and tilting up, and making it easier to connect with the rotating connecting rod 2221 to achieve rotational orientation.

[0123] Optionally, the pressing drive 252 can be, for example, a drive cylinder, a drive rod, or a combination of a drive motor and a transmission assembly. The accompanying drawings in this embodiment show the case where the pressing drive 252 is a drive cylinder. The pressing plate 253 is a long strip-shaped plate structure that extends along the length of the first fixture 212. When the pressing drive 252 drives the pressing plate 253 to press down, the long strip-shaped plate structure can cover the first fixture 212, thereby stably confining the rod 10 within the first fixture 212. It should be noted that the function of the pressing plate 253 in this embodiment is to confine the rod 10 onto the first fixture 212, rather than pressing the rod 10 tightly onto the first fixture 212. This configuration is more suitable for the rotational orientation assembly 22 to drive the rod 10 to rotate and orient the rod 10, resulting in a stable and reliable structure.

[0124] The rotational orientation process of the rod 10, in conjunction with the rod rotational orientation device 20 in this embodiment, is described in detail below:

[0125] First, the rods 10 are placed one by one on the first fixture 212. Then, the first conveyor belt 211 is moved to transport the rods 10 forward. When the rods 10 are transported to the side of the rotation orientation component 22, the first conveyor belt 211 stops moving, and the rotation orientation component 22 is used to rotate and orient the rods 10. For easier control, a sensor or other structure can be installed on the base 21. When the rods 10 are transported to the side of the rotation orientation component 22, the sensor can trigger a signal to the controller of the rod rotation orientation device 20, thereby controlling the first conveyor belt 211 to stop rotating and rotate and orient the rods 10. This process is repeated continuously, and the rods 10 on the first conveyor belt 211 can be rotated and oriented one by one.

[0126] When the rod 10 is driven to the side of the rotary orientation assembly 22, the pressing drive 252 controls the pressing plate 253 to move downward to confine the rod 10 within the first fixture 212. Subsequently, the first drive 2213 drives the moving frame 2212 to move towards the first conveyor belt 211, while the second drive 2214 drives the rotating connecting rod 2221 to rotate. When the rotating connecting rod 2221 moves to the square column head 12 near the end of the rod 10, the rotating connecting rod 2221 slowly rotates and advances. At this time, under the buffering effect of the elastic element 22112, the mating hole 2222 at the end of the rotating connecting rod 2221 mates with the square column head 12. After the two are in place, the first detection element 23 triggers a first detection signal to the control of the rod rotation orientation device. Upon receiving this signal, the controller controls the first drive 2213 to stop. The controller stops the operation and simultaneously controls the second drive component 2214 to reset. When the second detection element 24 detects that the second drive component 2214 has reset (the reset condition is that one of the detection holes 2223 is facing the detection component 223), the controller controls the second drive component 2214 to rotate 90° each time. After the second drive component 2214 drives the rotating connecting rod 2221 to rotate four times, the four sides of the square column head 12 are successively facing the detection component 223. When the detection component 223 passes through the detection hole 2223 and detects that the square column head 12 is provided with a mounting hole 121, it means that the mounting hole 121 on the square column head 12 is facing the correct direction. At this time, the controller controls the second drive component 2214 to stop working.

[0127] Subsequently, the first driving component 2213 is used to move the moving frame 2212 away from the first conveyor belt 211, and at the same time the lower pressure plate 253 is raised. The rod material 10 is moved to the next process by the robotic arm and other structures, which makes it easier to put the steel ball into the mounting hole 121. The structure is simple and easy to press the steel ball.

[0128] See Figure 12 and Figure 13As shown, after the rod 10 is rotated and oriented by the rod rotation and orientation device 20, the mounting hole 121 on the rod 10 faces upward. The first robotic arm 91 on the transfer device 90 can horizontally move the rod 10 onto the positioning fixture 311. After the rod 10 is placed in the positioning groove 3111, the position of the mounting hole 121 on the axis of the rod 10 may be offset, failing to meet the installation requirements of the next process. Additionally, the depth of the mounting hole 121 may not meet the subsequent installation requirements of the spring and steel ball. Therefore, it is necessary to position the rod 10 and remove any parts of the rod 10 that do not meet the design installation requirements. The rod positioning and detection device 30 in this embodiment is designed to position and detect the rod 10, enabling it to move the mounting hole 121 to the target position and remove any parts of the rod 10 whose mounting hole 121 does not meet the installation requirements.

[0129] This application specifically designs a rod positioning and detection device 30, which can position and detect rods 10, thereby improving the working efficiency of steel ball pressing equipment. The device includes a positioning fixture 311 on a fixture support 31, which has a positioning groove 3111. The rod 10 can be installed in the positioning groove 3111 and can reciprocate along the length of the groove 3111. A lifting and positioning assembly 32 includes a lifting drive 321 and a positioning pin 322. The length of the positioning pin 322 is aligned with the height of the fixture support 31. The bottom end of the positioning pin 322 has a conical tip 3221. The positioning pin 322 is located at the top of the positioning groove 3111 and is lifted and lowered by the lifting drive 321, allowing the conical tip 3221 to insert into the mounting hole 121 and move the rod 10 to a predetermined position. A detection assembly 33 is used at least to detect the lifting height of the positioning pin 322 to determine whether the depth of the mounting hole 121 meets the design requirements.

[0130] After the rod 10 is placed in the positioning groove 3111 of the positioning fixture 311, the rod 10 can reciprocate along the length of the positioning groove 3111. Specifically, when the lifting drive unit 321 lifts and lowers, it can drive the positioning pin 322 to lift and lower. When the positioning pin 322 descends, the conical tip 3221 at the bottom of the positioning pin 322 will be inserted into the mounting hole 121. When the positioning pin 322 continues to descend, the positioning pin 322 will pull the rod 10, which has deviated, to move a certain distance along its axis, so that the mounting hole 121 moves to the predetermined position, thus completing the positioning of the rod 10. Meanwhile, when the lifting drive unit 321 rises and falls, the lifting height of the positioning pin 322 can be detected by the detection component 33, which in turn can detect the depth of the mounting hole 121. If the depth of the mounting hole 121 exceeds the predetermined range, it indicates that the depth of the mounting hole 121 is too deep or too shallow, and cannot meet the subsequent assembly requirements of the spring and steel ball. At this time, the rod material 10 that does not meet the design requirements can be rejected. That is to say, through the rod material positioning detection device 30 in this embodiment, not only can the rod material 10 be positioned, but also the part of the rod material 10 that does not meet the design requirements can be rejected. In this way, the manual labor intensity in the steel ball pressing process can be reduced and the efficiency of steel ball pressing can be improved.

[0131] Optionally, in this embodiment, the outer diameter of the positioning pin 322 is smaller than the outer diameter of the mounting hole 121, which facilitates the insertion of the positioning pin 322 into the bottom of the mounting hole 121 and can improve the detection component 33's ability to effectively detect the depth of the mounting hole 121.

[0132] Furthermore, in this embodiment, the positioning fixture 311 has an elongated body structure, the positioning groove 3111 is a groove structure provided on the positioning fixture 311, the length direction of the positioning groove 3111 is consistent with the length direction of the positioning fixture 311, and the lifting positioning component 32 is provided at the end of the positioning fixture 311.

[0133] Optionally, the lifting drive unit 321 in this embodiment includes a lifting cylinder, which is installed on the outside of the fixture bracket 31. A mounting part 37 is provided on the top of the lifting cylinder, and a positioning pin 322 is suspended on the mounting part 37. When the lifting cylinder drives the mounting part 37 to rise or fall, it can also drive the positioning pin 322 to rise or fall to position the rod material 10. Of course, in other embodiments of this application, the lifting drive unit 321 can also be configured as a structure capable of driving the mounting part 37 to rise or fall, such as a motor and a lead screw assembly.

[0134] Specifically, the mounting part 37 in this embodiment includes a mounting plate 373 and a mounting block 371. The mounting plate 373 is mounted on the top of the lifting cylinder. The mounting block 371 has an oblong hole 372, and the mounting block 371 is mounted on the top of the mounting plate 373 by a locking member (not shown in the figure) passing through the oblong hole 372. The positioning pin 322 is suspended on the mounting block 371. By providing the oblong hole 372 on the mounting block 371, when the locking member is released, the mounting block 371 can be rotated and moved, and the suspended position of the positioning pin 322 can be adjusted, thereby adjusting the positioning pin 322 to the required position for easier use. Exemplarily, the locking member in this embodiment can be a locking screw, locking pin, or locking bolt, etc. Any other modifications within the concept of this application are within the protection scope of this application.

[0135] See you again Figure 12 and Figure 13 As shown, the detection component 33 in this embodiment includes a laser displacement sensor, which is installed on the lifting and positioning component 32. When the lifting drive unit 321 lifts and lowers, it can drive the laser displacement sensor and the positioning pin 322 to lift and lower, thereby detecting the lifting height of the positioning pin 322 and the depth of the positioning pin 322 inserted into the mounting hole 121. This allows the removal of parts of the rod material 10 that do not meet the design requirements.

[0136] Furthermore, the rod positioning and detection device 30 also includes a scrap bin 35, a transfer device 90, and a controller. The scrap bin 35 is located outside the fixture support 31. The controller is electrically connected to the detection component 33, and controls the transfer device 90 to move between the scrap bin 35 and the positioning fixture 311 based on signals transmitted by the detection component 33. Specifically, when the detection component 33 detects that the depth of the mounting hole 121 on the rod 10 exceeds a predetermined range, the controller controls the transfer device 90 to move the rod 10 that does not meet the design requirements from the positioning fixture 311 into the scrap bin 35.

[0137] In order to facilitate the clamping of the rod 10 in the positioning fixture 311, the positioning groove 3111 in this embodiment is provided with a clearance recess 3113 on the opposite side walls. The clearance recess 3113 is used to avoid the transfer device 90 that moves the rod 10. Through the function of the clearance recess 3113, the transfer device 90 can be avoided, which is more suitable for the transfer device 90 to clamp and transfer the rod 10.

[0138] Furthermore, in this embodiment, a first rod detection element 312 is provided on the fixture support 31. This first rod detection element 312 is used to detect whether a rod 10 is placed in the positioning groove 3111. Through the function of the first rod detection element 312, automatic control of the rod positioning detection device can be easily realized. Optionally, the first rod detection element 312 can be a structure such as a laser sensor. Any other modifications under the concept of this application are within the protection scope of this application.

[0139] After the rod material 10 is positioned and inspected, the qualified rod material 10 will be moved to the spring delivery device 40 by the transfer device 90. In order to prevent the position of the rod material 10 from shifting, the rod material 10 will be fixed before the transfer device 90 clamps and transfers it. For this purpose, the rod material positioning and inspection device 30 in this embodiment is also provided with a clamping component 34.

[0140] To facilitate the clamping assembly 34 in clamping and positioning the rod 10, a clearance notch 3112 is provided at the end of the positioning groove 3111 in this embodiment. In use, the rod 10 can extend out of the positioning groove 3111 through the clearance notch 3112. The clamping assembly 34 is disposed at the end of the fixture support 31 to clamp the end of the rod 10 extending from the clearance notch 3112. After the clamping assembly 34 clamps and fixes the end of the rod 10, the transfer device 90 will not cause any movement of the rod 10 when transferring it. Furthermore, when the transfer device 90 clamps the rod 10 and moves it horizontally, it will not cause any movement of the rod 10 in the axial direction. Optionally, the transfer device 90 includes a robotic arm that can clamp the rod 10 and move between the positioning fixture 311 and the waste bin 35, facilitating the removal of defective rods 10.

[0141] Optionally, the clamping assembly 34 in this embodiment includes a clamping positioning block 341, a first clamping block 342, a second clamping block 343, and a clamping block drive (not shown in the figure). The clamping positioning block 341 is provided with a clamping block groove 3411; the first clamping block 342 is mounted on the clamping positioning block 341 and can slide along the clamping block groove 3411; the second clamping block 343 is mounted on the clamping positioning block 341 and can slide along the clamping block groove 3411; the clamping block drive is drivenly connected to the first clamping block 342 and the second clamping block 343, thereby driving the first clamping block 342 and the second clamping block 343 to move closer or further apart. When the clamping block drive member drives the first clamping block 342 and the second clamping block 343 to move closer together, the end of the rod 10 extending from the clearance notch 3112 can be clamped, thereby fixing the rod 10 within the positioning fixture 311; when the clamping block drive member drives the first clamping block 342 and the second clamping block 343 to move away from each other, the fixing of the rod 10 can be released. For example, the clamping block drive member can be a drive cylinder, or a combination of a drive motor and a lead screw assembly, etc. Any other modifications within the scope of this application are within the protection scope of this application.

[0142] After the rod material 10 is positioned and inspected, the qualified rod material 10 on the positioning fixture 311 can be transferred to the spring delivery device 40 for delivery of the spring 70 by the action of the transfer device 90.

[0143] See Figures 14 to 17 As shown, the spring feeding device 40 in this embodiment includes a positioning bracket 41 and a spring feeding assembly 42. The positioning bracket 41 is equipped with a rod jig 401, which has a limiting groove 411 for mounting the rod 10. The spring feeding assembly 42 includes a spring vibrator 421, a spring conveying component 422, and a spring unloading component 423. The spring vibrator 421 is mounted on the outside of the positioning bracket 41. The spring unloading component 423 is positioned directly above the mounting hole 121 of the rod 10 to feed the spring 70 into the mounting hole 121. The spring conveying component 422 connects the spring vibrator 421 and the spring unloading component 423 to convey the spring 70.

[0144] During operation, the rod material 10 is first moved and placed on the rod material fixture 401 using the transfer device 90. Then, the spring 70 is placed inside the spring vibrator 421. When the spring vibrator 421 operates, it vibrates and transmits the spring 70 to the spring conveying component 422, and then into the spring unloading component 423. After the spring 70 enters the spring unloading component 423, it is placed into the mounting hole 121 from directly above it by the action of the spring unloading component 423. In other words, through the function of the spring unloading device in this embodiment, the spring 70 can be automatically placed into the mounting hole 121, enabling automatic assembly of the spring 70 and improving the assembly efficiency of the entire steel ball pressing equipment.

[0145] Furthermore, in this embodiment, the rod material fixture 401 has an elongated body structure, and the limiting groove 411 is a recessed structure provided on the rod material fixture 401. The length direction of the limiting groove 411 is consistent with the length direction of the rod material fixture 401. The spring feeding assembly 42 is provided at the end of the rod material fixture 401, which facilitates the automatic placement of the spring 70 into the mounting hole 121. Furthermore, the spring feeding assembly 42 in this embodiment also includes a lifting component 424, which includes a lifting cylinder 4241 and a lifting bracket 4242. The lifting cylinder 4241 is installed on the outside of the positioning bracket 41; the lifting bracket 4242 is installed on the lifting cylinder 4241 and moves up and down under the drive of the lifting cylinder 4241; the spring unloading component 423 is installed on the lifting bracket 4242. Through the action of the lifting component 424, the spring unloading component 423 can be driven to move towards the mounting hole 121, thereby stably placing the spring 70 into the mounting hole 121.

[0146] Optionally, the lifting bracket 4242 in this embodiment can be a frame structure, a support plate, or other structures that can support the spring unloading component 423. Any other modifications under the concept of this application are within the protection scope of this application.

[0147] Furthermore, the spring conveying component 422 in this embodiment includes structures such as a conveying hose. Any other deformation method that can transmit the spring 70 from the spring vibrator 421 to the spring unloading component 423 is within the protection scope of this application.

[0148] See you again Figures 14 to 17As shown, the spring feeding component 423 includes a spring feeding tube 4231 and a limiting and dispensing mechanism 4232. The spring feeding tube 4231 is fixedly mounted on the lifting bracket 4242, with its opening directly above the mounting hole 121. The limiting and dispensing mechanism 4232 is mounted on the lifting bracket 4242 to dispense and limit the spring 70 within the spring feeding tube 4231. When the lifting component 424 moves up and down, it lowers the spring feeding tube 4231 until it aligns with the mounting hole 121, facilitating precise dispensing of the spring 70. The limiting and dispensing mechanism 4232 ensures that the spring 70 within the spring feeding tube 4231 is dispensed into the mounting hole 121 at the appropriate time.

[0149] Specifically, in this embodiment, the spring feed tube 4231 has a first clearance through hole 42311 and a second clearance through hole 42312 respectively provided on the opposite side walls. The first clearance through hole 42311 and the second clearance through hole 42312 are spaced apart along the vertical direction of the spring feed tube 4231, and the distance between the first clearance through hole 42311 and the second clearance through hole 42312 is greater than the length of one spring 70 but less than the sum of the lengths of two springs 70. It can be understood that the length of the spring 70 mentioned here refers to the length of the spring 70 in its natural state. The limiting and dispensing mechanism 4232 includes a limiting and dispensing block 42321 and a moving cylinder 42322. The limiting and dispensing block 42321 is mounted on the lifting bracket 4242. The limiting and dispensing block 42321 is provided with a clearance part 423211. The spring feed tube 4231 passes through the clearance part 423211. A first blocking pin 423212 and a second blocking pin 423213 are respectively provided on opposite sides of the clearance part 423211. The first blocking pin 423212 is perpendicular to the spring feed tube 4231 and parallel to the second blocking pin 423212. A first clearance through hole 42311 is directly opposite, and a second blocking pin 423213 is perpendicular to the spring feed tube 4231 and directly opposite the second clearance through hole 42312; a moving cylinder 42322 is mounted on a lifting bracket 4242, and the moving cylinder 42322 is driven to connect with the limiting delivery block 42321 to drive the limiting delivery block 42321 to slide back and forth, thereby driving the first blocking pin 423212 to be inserted into the first clearance through hole 42311 or driving the second blocking pin 423213 to be inserted into the second clearance through hole 42312.

[0150] After the lifting bracket 4242 descends to its position, the moving cylinder 42322 drives the limiting release block 42321 to reciprocate. Specifically, when the moving cylinder 42322 drives the first blocking pin 423212 to insert into the first clearance through hole 42311, it can stop the springs 70 in the spring feed tube 4231 except for the lowest spring 70 in the spring feed tube 4231. At the same time, the second blocking pin 423213 will shift away from the spring feed tube 4231. At this time, the spring 70 located at the bottom of the first blocking pin 423212 will fall directly into the mounting hole 121, completing the release of the spring 70. When the moving cylinder 42322 drives the second blocking pin 423213 to insert into the second clearance through hole 42312, the second blocking pin 423213 can stop all the springs 70 in the spring feed tube 4231. At this time, the springs 70 located at the bottom of the first blocking pin 423212 will fall directly into the mounting hole 121. This facilitates the placement of the rod material 10 or the vibration transmission of the springs 70 to the spring feed tube 4231.

[0151] Of course, in other embodiments of this application, the moving cylinder 42322 and the lifting cylinder 4241 can also be replaced by a motor and a lead screw assembly. Any other modifications under the concept of this application are within the protection scope of this application.

[0152] Furthermore, in this embodiment, the spring feeding tube 4231 is also provided with a detection through hole 42313. The extension direction of the detection through hole 42313 is perpendicular to the length direction of the spring feeding tube 4231, and the detection through hole 42313 is located at the bottom of the second clearance through hole 42312. The limiting and placing mechanism 4232 is provided with a spring detection element 423214, which is directly opposite to the detection through hole 42313. When the spring 70 falls downward, it will pass through the detection through hole 42313. At this time, the spring detection element 423214 will detect the spring 70 passing through the detection through hole 42313, and then determine whether the spring 70 has fallen and been placed in the mounting hole 121. Optionally, the spring detection element 423214 can be an infrared sensor or a laser sensor, etc.

[0153] Furthermore, a sensor 42421 is installed on the lifting bracket 4242. This sensor 42421 is located at the inlet end of the spring feeding tube 4231 to detect whether the spring feeding tube 4231 is full of springs 70. When the sensor 42421 detects that the spring feeding tube 4231 is full of springs 70, the spring vibrator 421 can be controlled to stop working, thereby reducing the energy consumption of the spring dispensing device. At the same time, when the sensor 42421 detects that the spring feeding tube 4231 is full of springs 70, it is easier to control the lifting cylinder 4241, making it easier to achieve automatic dispensing of springs 70.

[0154] Furthermore, in this embodiment, the positioning bracket 41 is provided with a rod detection element 412, which is used to detect whether a rod 10 is placed in the limiting groove 411. Through the function of the rod detection element 412, automatic control of the spring dispensing device can be easily realized. Optionally, the rod detection element 412 can be a structure such as a laser sensor. Any other modifications under the concept of this application are within the protection scope of this application.

[0155] After the spring 70 is delivered, the rod 10 is moved by the transfer device 90 to the steel ball delivery device 50. In order to prevent the position of the rod 10 from shifting, the rod 10 is fixed before the transfer device 90 clamps and delivers it. For this purpose, the spring delivery device 40 in this embodiment is also provided with a clamping component 45.

[0156] To facilitate the clamping component 45 in clamping and positioning the rod 10, the end of the limiting groove 411 in this embodiment is provided with a clearance notch 413. In use, the rod 10 can extend out of the limiting groove 411 through the clearance notch 413. The clamping component 45 is disposed at the end of the positioning bracket 41 to clamp the end of the rod 10 extending out of the clearance notch 413. After the clamping component 45 clamps and fixes the end of the rod 10, when the transfer device 90 moves the rod 10 horizontally, it will not cause any movement in the axial direction of the rod 10, which facilitates the feeding of steel balls in the next process.

[0157] Optionally, the clamping component 45 includes a clamping block positioning plate 451, a first clamping block 452, a second clamping block 453, and a clamping block driving member (not shown in the figure). The clamping block positioning plate 451 has a clamping block sliding groove 4511; the first clamping block 452 is mounted on the clamping block positioning plate 451 and can slide along the clamping block sliding groove 4511; the second clamping block 453 is mounted on the clamping block positioning plate 451 and can slide along the clamping block sliding groove 4511; the clamping block driving member is drivenly connected to the first clamping block 452 and the second clamping block 453 to drive the first clamping block 452 and the second clamping block 453 to move closer to or further away from each other. When the clamping block drive member drives the first clamping block 452 and the second clamping block 453 to move closer together, the end of the rod 10 extending from the clearance notch 413 can be clamped, thereby fixing the rod 10 inside the rod jig 401; when the clamping block drive member drives the first clamping block 452 and the second clamping block 453 to move away from each other, the fixing of the rod 10 can be released. For example, the clamping block drive member can be a drive cylinder, or a combination of a drive motor and a lead screw assembly, etc. Any other modifications within the scope of this application are within the protection scope of this application.

[0158] After the spring 70 is released, the rod 10 can be transferred to the steel ball releasing device 50 for the release of steel balls 60 by the action of the transfer device 90.

[0159] See Figures 18 to 23 As shown, the steel ball dispensing device 50 in this embodiment includes a support bracket 51 and a steel ball feeding assembly 52. ​​The support bracket 51 is provided with a support fixture 511, which has a limiting groove 5111 for mounting on the rod 10. The steel ball feeding assembly 52 includes a feeding funnel 521, a steel ball conveying component 522, and a steel ball unloading component 523. The feeding funnel 521 is located on the outside of the support bracket 51, and the steel ball unloading component 523 is located on top of the support bracket 51, directly above the mounting hole 121, for dispensing steel balls 60 into the mounting hole 121. The steel ball conveying component 522 connects the feeding funnel 521 and the steel ball unloading component 523 for conveying the steel balls 60.

[0160] During operation, the rod material 10 is first moved and placed on the support fixture 511 using the transfer device 90. Then, steel balls 60 are placed in the feeding funnel 521. Under their own gravity, the steel balls 60 are transferred from the feeding funnel 521 to the steel ball conveying component 522, and then into the steel ball unloading component 523. Once the steel balls 60 are in the steel ball unloading component 523, they can be dispensed into the mounting hole 121 from directly above. In other words, through the steel ball dispensing device 50 in this embodiment, the steel balls 60 can be automatically dispensed into the mounting hole 121, reducing the intensity of manual labor and improving the assembly efficiency of the entire steel ball pressing equipment.

[0161] To facilitate the feeding of steel balls 60, the feeding funnel 521 in this embodiment is supported on the side of the support bracket 51 by a bracket or the like. When the steel balls 60 are placed in the feeding funnel 521, they may become compressed and unable to flow smoothly into the steel ball conveying component 522. Therefore, the feeding funnel 521 in this embodiment is provided with a cover plate 524, which has a loosening mechanism. This loosening mechanism can be a stirring mechanism or a telescopic mechanism, etc. This embodiment shows the case where the loosening mechanism is a telescopic cylinder 525. When the telescopic cylinder 525 extends or retracts, it can loosen the steel balls 60 in the feeding funnel 521, facilitating their flow from the feeding funnel 521 into the steel ball conveying component 522.

[0162] Optionally, the cover plate 524 in this embodiment includes a first semi-circular plate 5241 and a second semi-circular plate 5422. The first semi-circular plate 5241 is fixed to the top of the feeding funnel 521, and the second semi-circular plate 5422 is rotatably connected to the first semi-circular plate 5241. This arrangement facilitates the flipping and opening of the second semi-circular plate 5422 to allow the steel ball 60 to be placed into the feeding funnel 521. In actual installation, the telescopic cylinder 525 is installed on the first semi-circular plate 5241, which further facilitates the flipping of the second semi-circular plate 5422. Specifically, the second semi-circular plate 5422 can be rotatably connected to the first semi-circular plate 5241 via a hinge or pivot, resulting in a simple structure that is easy to assemble.

[0163] Furthermore, the steel ball feeding assembly 52 in this embodiment also includes a lifting mechanism 526, which includes a lifting drive cylinder 5261 and a lifting frame 5262. The lifting drive cylinder 5261 is mounted on the outside of the support bracket 51; the lifting frame 5262 is mounted on the lifting drive cylinder 5261 and moves up and down under the drive of the lifting drive cylinder 5261; the steel ball unloading component 523 is mounted on the lifting frame 5262. Through the action of the lifting mechanism 526, the steel ball unloading component 523 can be driven to move towards the mounting hole 121, thereby stably and accurately placing the steel ball 60 into the mounting hole 121.

[0164] Optionally, the lifting frame 5262 in this embodiment can be a frame structure, a support plate, or other structures that can support the steel ball unloading component 523. Any other variations of the concept of this application are within the protection scope of this application.

[0165] Furthermore, the steel ball feeding component 523 in this embodiment includes structures such as a conveying hose. Any other deformation that can transfer the steel ball 60 from the feeding funnel 521 to the steel ball feeding component 523 is within the protection scope of this application.

[0166] See Figure 19 , Figures 21 to 23 As shown, the steel ball feeding component 523 in this embodiment includes a steel ball feeding tube 5231 and a limiting and dispensing mechanism 5232. The steel ball feeding tube 5231 is fixedly installed on the lifting frame 5262, and the tube hole of the steel ball feeding tube 5231 is located directly above the mounting hole 121. The limiting and dispensing mechanism 5232 is installed on the lifting frame 5262 to dispense and limit the steel ball 60 in the steel ball feeding tube 5231. When the lifting frame 5262 rises and falls, it can drive the steel ball feeding tube 5231 to descend, so that the steel ball feeding tube 5231 descends to dock with the mounting hole 121, which facilitates the accurate dispensing of the steel ball 60. Through the action of the limiting and dispensing mechanism 5232, the steel ball 60 in the steel ball feeding tube 5231 can be dispensed into the mounting hole 121 at the appropriate time.

[0167] Specifically, in this embodiment, a first clearance hole 52311 and a second clearance hole 52312 are respectively provided on the opposite side walls of the steel ball feeding tube 5231. The first clearance hole 52311 and the second clearance hole 52312 are spaced apart along the vertical direction of the steel ball feeding tube 5231, and the distance between the first clearance hole 52311 and the second clearance hole 52312 is greater than the diameter of one steel ball 60 but less than the sum of the diameters of two steel balls 60. The limiting and dispensing mechanism 5232 includes a limiting slider 52321 and a moving cylinder 52322. The limiting slider 52321 is installed on the lifting frame 5262. The limiting slider 52321 is provided with a clearance part 523211. The steel ball feeding tube 5231 passes through the clearance part 523211. The clearance part 523211 is provided with a blocking rod 523212 and a blocking plate 523213 on opposite sides. The blocking rod 523212 is directly opposite to the first clearance hole 52311, and the blocking plate 523213 is directly opposite to the second clearance hole 52312. The moving cylinder 52322 is installed on the lifting frame 5262. The moving cylinder 52322 is driven to connect with the limiting slider 52321 to drive the limiting slider 52321 to slide back and forth, thereby driving the blocking rod 523212 to be inserted into the first clearance hole 52311 or driving the blocking plate 523213 to be inserted into the second clearance hole 52312.

[0168] After the lifting frame 5262 descends to its position, the moving cylinder 52322 drives the limiting slider 52321 to reciprocate. Specifically, when the moving cylinder 52322 drives the blocking rod 523212 to insert into the first clearance hole 52311, it can hold the steel ball 60 at the first clearance hole 52311, thereby stopping all steel balls 60 except the lowest one in the steel ball feeding tube 5231 within the steel ball feeding tube 5231. At the same time, the blocking plate 523213 will shift away from the steel ball feeding tube 5231. At this time, the steel ball 60 located at the bottom of the blocking rod 523212 will fall directly into the mounting hole 121, completing the feeding of the steel ball 60. When the moving cylinder 52322 drives the blocking plate 523213 to insert into the second clearance hole 52312, it can hold or support the steel ball 60 at the second clearance hole 52312. That is, the blocking plate 523213 can stop all the steel balls 60 in the steel ball feeding tube 5231. At this time, the steel ball 60 at the bottom of the blocking plate 523213 will fall directly into the mounting hole 121. This facilitates the placement of the rod material 10 or the transfer of the steel ball 60 to the steel ball feeding tube 5231.

[0169] Of course, in other embodiments of this application, the moving cylinder 52322 and the lifting drive cylinder 5261 can also be replaced by a motor and a lead screw assembly. Any other modifications under the concept of this application are within the protection scope of this application.

[0170] Furthermore, in this embodiment, an elastic element 523214 is provided between the blocking rod 523212 and the limiting slider 52321, and the end of the blocking rod 523212 away from the steel ball feeding tube 5231 can pass through the limiting slider 52321; a sensor 52621 is provided on the lifting frame 5262, which is used to sense the end of the blocking rod 523212 away from the steel ball feeding tube 5231. Optionally, the elastic element 523214 is a spring, an elastic pad, or an elastic sleeve, etc. When the moving cylinder 52322 drives the limiting slider 52321 to move, and the blocking rod 523212 is inserted into the steel ball feeding tube 5231, if the blocking rod 523212 abuts against the steel ball 60 in the steel ball feeding tube 5231, the end of the blocking rod 523212 will be squeezed out of the limiting slider 52321. At this time, the sensor 52621 can sense the protruding end of the blocking rod 523212, indicating that there is a steel ball 60 in the steel ball feeding tube 5231. Conversely, when the moving cylinder 52322 drives the limiting slider 52321 to move, causing the blocking rod 523212 to insert into the ball feed tube 5231, if the blocking rod 523212 does not abut against the ball 60 inside the ball feed tube 5231, the end of the blocking rod 523212 will not be squeezed out of the limiting slider 52321. At this time, the sensor 52621 cannot sense the protruding end of the blocking rod 523212, indicating that there is no ball 60 inside the ball feed tube 5231. In other words, the sensor 52621 can detect and sense whether there is a ball 60 inside the ball feed tube 5231.

[0171] Furthermore, in this embodiment, a second rod detection element 512 is provided on the support bracket 51. The second rod detection element 512 is used to detect whether a rod 10 is placed in the limiting groove 5111. Through the function of the second rod detection element 512, automatic control of the steel ball dispensing device can be easily realized. Optionally, the second rod detection element 512 can be a structure such as a laser sensor. Any other modifications under the concept of this application are within the protection scope of this application.

[0172] After the steel ball 60 is inserted, the rod 10 is moved by the transfer device 90 to the steel ball pressing device 100. In order to prevent the position of the rod 10 from shifting, the rod 10 is fixed before the transfer device 90 clamps and transfers it. For this purpose, the steel ball pressing device 100 in this embodiment is also provided with a locking mechanism 53.

[0173] To facilitate the clamping and positioning of the rod 10 by the locking mechanism 53, the end of the limiting groove 5111 in this embodiment is provided with a clearance slot 5112. In use, the rod 10 can extend out of the limiting groove 5111 from the clearance slot 5112. The locking mechanism 53 is provided at the end of the support bracket 51 to clamp the end of the rod 10 extending from the clearance slot 5112. After the locking mechanism 53 clamps and fixes the end of the rod 10, when the transfer device 90 moves the rod 10 horizontally, it will not cause any movement in the axial direction of the rod 10, which facilitates the pressing of steel balls in the next process.

[0174] Optionally, the locking mechanism 53 includes a locking mounting plate 531, a first locking block 532, a second locking block 533, and a locking drive (not shown in the figure). The locking mounting plate 531 has a locking groove 5311; the first locking block 532 is mounted on the locking mounting plate 531 and can slide along the locking groove 5311; the second locking block 533 is mounted on the locking mounting plate 531 and can slide along the locking groove 5311; the locking drive is driven to connect with the first locking block 532 and the second locking block 533 to drive the first locking block 532 and the second locking block 533 to move closer or further apart. When the locking drive drives the first locking block 532 and the second locking block 533 closer together, it can clamp the end of the rod 10 extending from the clearance slot 5112, thereby fixing the rod 10 within the support fixture 511; when the clamping drive drives the first locking block 532 and the second locking block 533 further apart, it can release the fixation of the rod 10. For example, the locking drive component can be a drive cylinder, or a combination of a drive motor and a lead screw assembly, etc. Any other variation within the concept of this application is within the protection scope of this application. Of course, in other embodiments of this application, the locking mechanism 53 can also be configured as a locking pin or a retaining pin, etc.

[0175] Combination Figures 1 to 4 , Figure 25 by Figure 26 As shown, after the steel ball 60 is placed in the mounting hole 121 on the rod 10, the rod 10 can be transferred to the steel ball pressing device 100 for pressing the steel ball 60 by the action of the transfer device 90.

[0176] Specifically, the steel ball pressing device 100 is mounted on the base 80. This device includes a pressing fixture 101 and a pressing machine 102. The pressing fixture 101 supports the rod material 10, and the pressing machine 102 presses the rod material 10 to press and fix the steel ball 60 placed in the mounting hole 121 within the mounting hole 121. The structure is simple and easy to implement. It should be noted that the structure of the pressing fixture 101 in this embodiment is consistent with the structure of the rod material fixture 401 and the support fixture 511, and will not be described again here.

[0177] In this embodiment, the pressing fixture 101 is equipped with a steel ball detection element 103. This steel ball detection element 103 can be a laser displacement sensor or an infrared scanner, etc. During the process of the transfer device 90 placing the rod 10 from the steel ball feeding device 50 into the pressing fixture 101, steel balls 60 may occasionally roll off. In this embodiment, by setting the steel ball detection element 103 on the pressing fixture 101 to detect the steel balls 60 on the rod 10, the press machine 102 can avoid empty pressure. Specifically, when the steel ball detection element 103 detects that there is a steel ball 60 on the rod 10 placed on the pressing fixture 101, the controller of the steel ball pressing equipment controls the pressing machine 102 to press down and punch the rod 10, causing the square column head 12 to deform, thereby limiting the steel ball 60 in the mounting hole 121; when the steel ball detection element 103 detects that there is no steel ball 60 on the rod 10 placed on the pressing fixture 101, the controller of the steel ball pressing equipment controls the pressing machine 102 to stop operating, so as to avoid the pressing machine 102 being pressurized without pressure.

[0178] Furthermore, in this embodiment, the base 80 is provided with a first collection chamber 81 and a second collection chamber 82. The first collection chamber 81 is used to collect rod material 10 without steel balls 60 on the pressing fixture 101, and the second collection chamber 82 is used to collect rod material 10 with steel balls 60 pressed on. The controller of the steel ball pressing equipment is communicatively connected to the steel ball detection element 103 to control the transfer device 90 to transfer the rod material 10 between the pressing fixture 101, the first collection chamber 81 and the second collection chamber 82. Specifically, when the steel ball detection element 103 detects that there is a steel ball 60 on the rod material 10 placed on the pressing fixture 101, the controller controls the transfer device 90 to transfer the rod material 10 on the pressing fixture 101 to the first collection bin 81. After the controller controls the pressing machine 102 to press down and punch the rod material 10, the controller will control the transfer device 90 to transfer the rod material 10 on the pressing fixture 101 to the second collection bin 82. In this way, it is convenient to distinguish and collect the rod material 10.

[0179] In this embodiment, the transfer device 90 is used to sequentially place and move the rod 10 along the direction of the first fixture 212, the positioning fixture 311, the rod fixture 401, the support fixture 511, and the pressing fixture 101. Specifically, in this embodiment, the first fixture 212, the positioning fixture 311, the rod fixture 401, the support fixture 511, and the pressing fixture 101 are arranged side by side along the same straight line; and the transfer device 90 includes a first robotic arm 91, a second robotic arm 92, a third robotic arm 93, a fourth robotic arm 94, a fifth robotic arm 95, and a linear guide rail 96, wherein the first robotic arm 91 is used to clamp and move the rod 10 between the first fixture 212 and the positioning fixture 311; the second robotic arm 92, the third robotic arm 93, the fourth robotic arm 94, the fifth robotic arm 95, the third robotic arm 96, the fifth robotic arm 97, the fifth robotic arm 98, the fifth robotic arm 99, the sixth robotic arm 9 ... sixth robotic arm 99, the fifth robotic arm 99, the sixth robotic arm 99, the sixth robotic arm Hand 94 and fifth robot 95 are mounted on base 80 via the same linear guide rail 96. Second robot 92 is used to clamp and move rod 10 between positioning fixture 311 and rod fixture 401; third robot 93 is used to clamp and move rod 10 between rod fixture 401 and support fixture 511; fourth robot 94 is used to clamp and move rod 10 between support fixture 511 and pressing fixture 101; fifth robot 95 is used to clamp and transfer rod 10 between pressing fixture 101, first collection bin 81 and second collection bin 82. Through the actions of the first robotic arm 91, the second robotic arm 92, the third robotic arm 93, the fourth robotic arm 94, and the fifth robotic arm 95, the rod material 10 can be placed one by one on the first fixture 212, the positioning fixture 311, the rod material fixture 401, the support fixture 511, and the pressing fixture 101 for corresponding operations. The structure is simple and easy to implement. Meanwhile, by mounting the second robotic arm 92, the third robotic arm 93, the fourth robotic arm 94, and the fifth robotic arm 95 on the same linear guide rail 96, the rod material 10 will not move axially during movement. A single positioning operation can confine the mounting hole 121 on the rod material 10 to a predetermined position, facilitating the accurate placement of the spring 70 and the steel ball 60, and further improving the working efficiency of the steel ball pressing equipment in this embodiment.

[0180] In summary, the steel ball pressing equipment in this embodiment, by setting up a rod material rotation and orientation device 20, a rod material positioning and detection device 30, a spring delivery device 40, a steel ball delivery device 50, a steel ball pressing device 100, and a transfer device 90, can realize automatic rotation and orientation of the rod material 10, orientation detection of the rod material 10, automatic delivery of the spring 70, automatic delivery of the steel ball 60, and pressing of the steel ball 60. This can greatly reduce the intensity of manual labor and improve the pressing efficiency of the steel ball 60.

[0181] The above are merely preferred embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
