[0019] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0020] In the field of electrical products, especially fans and vertical heaters, the shaking and steering function is relatively common. The steel ball bracket assembly, as the key structure connecting the upper and lower parts of the shaking head, plays an important role in supporting and ensuring the smooth shaking of the head during product operation. The traditional assembly method of the steel ball bracket assembly mainly relies on manual operation. The operator needs to manually take the steel ball seat (steel ball bracket) and then press the steel balls in one by one. This process is labor-intensive and extremely inefficient. The average assembly time of each steel ball bracket is as long as 8-10 seconds. With the expansion of production scale and the improvement of efficiency requirements, this manual assembly method can no longer meet production needs and has become a bottleneck restricting the improvement of production efficiency.

[0021] Based on this, the present application provides a steel ball automatic press-fitting device.

[0022] Example 1 like Figure 1-Figure 8 As shown, this embodiment provides a steel ball automatic press-fitting device, comprising: A press-fitting host 100, on which a steel ball press-fitting mechanism 4 is provided, the steel ball press-fitting mechanism 4 comprises a press-fitting frame 41, a positioning plate 44 to be pressed and a press-fitting module 45; the press-fitting frame 41 is provided with a first driving device 42 that drives the positioning plate 44 to be pressed to move up and down, and the positioning plate 44 to be pressed is provided with a plurality of accommodating ports for accommodating steel balls; the press-fitting module 45 is arranged above the positioning plate 44 to be pressed, the press-fitting frame 41 is provided with a second driving device 43 that drives the pressing module 45 to move up and down, and the pressing module 45 is provided with a plurality of press-fitting heads 451, and each of the press-fitting heads 451 corresponds to one of the accommodating ports respectively; A steel ball seat feeding mechanism, which supplies steel ball seats to the steel ball pressing mechanism 4; A steel ball feeding mechanism 8 supplies steel balls to the receiving port.

[0023] The above-mentioned automatic press-fitting device for steel balls, during use, the steel ball seat feeding mechanism will orderly convey the pre-processed and qualified steel ball seats to the steel ball press-fitting mechanism 4, and the steel ball feeding will accurately convey the steel balls one by one to the receiving port of the positioning plate 44 to be pressed of the steel ball press-fitting mechanism 4 of the press-fitting host 100. When the steel ball seat and the steel ball are ready, the press-fitting host 100 starts working. The first driving device 42 on the press-fitting frame 41 drives the positioning plate 44 to be pressed to move downward, so that the positioning plate 44 to be pressed is pressed down and fits tightly with the steel ball seat, ensuring that the steel ball seat will not be displaced during the press-fitting process. Then the second driving device 43 drives the press-fitting module 45 to move downward, and the multiple press-fitting heads 451 on the press-fitting module 45 simultaneously apply sufficient pressure to the steel balls in the corresponding receiving ports, and the steel balls are steadily pressed into the predetermined holes of the steel ball seat. During the entire press-fitting process, the pressure and stroke of the press-fitting head 451 are precisely controlled, which can ensure that the steel ball is firmly installed on the steel ball seat without damaging the steel ball seat or the steel ball due to excessive pressure. Since the device realizes the automatic loading and automatic press-fitting process of the steel ball and the steel ball seat, there is no need for manual operation one by one. Compared with the traditional manual assembly method, it greatly shortens the assembly time of a single steel ball seat, can meet the needs of large-scale production, and reduce dependence on manual labor, thereby reducing labor costs. In addition, during the automatic press-fitting process, the press-fitting position and force of the steel ball are controlled by precise mechanical devices, avoiding errors and inconsistencies that may be caused by manual operation. Each steel ball can be accurately pressed into the corresponding position of the steel ball seat, and the press-fitting force is uniform, making the quality of the steel ball bracket assembly more stable and reliable.

[0024] Specifically, a plurality of the accommodating openings are provided on the positioning plate to be pressed 44, and the plurality of the accommodating openings are evenly distributed on the positioning plate to be pressed 44 along the circumference of the positioning plate to be pressed 44; Each of the accommodating ports penetrates the positioning plate 44 to be pressed along the thickness direction of the positioning plate 44 to be pressed, and a steel ball limiting structure 46 is provided on one side of each of the accommodating ports; the limiting structure includes an elastic member 461 and a limiting head 462, and the limiting head 462 is provided on one side of the accommodating port along the radial direction of the accommodating port, one end of the elastic member 461 is connected to the limiting head 462, and the other end is fixed on the positioning plate 44 to be pressed.

[0025] On the positioning plate 44 to be pressed of the automatic pressing device for steel balls, 6-8 receiving ports are evenly arranged according to the design requirements of the steel ball seat. For example, in an assembly operation, the steel ball seat that meets the specifications is accurately transported to the steel ball pressing mechanism 4 through the steel ball seat feeding mechanism. At the same time, the steel ball feeding mechanism 8 transports the steel ball to the receiving port of the positioning plate 44 to be pressed. A steel ball limiting structure 46 is installed on one side of each receiving port. The elastic member 461 can be made of a high-strength coil spring, and the limiting head 462 is made of wear-resistant alloy steel. When the steel ball enters the receiving port, the steel ball will squeeze the limiting head 462, causing the elastic member 461 to undergo elastic deformation. The limiting head 462 generates a moderate clamping force on the steel ball under the action of the elastic member 461, ensuring that the steel ball maintains a stable position in the receiving port and will not be offset or fall off due to slight vibration of the device or other external forces.

[0026] During the press-fitting process, the press-fitting head 451 of the press-fitting module 45 accurately presses the steel ball into the corresponding hole of the steel ball seat according to the predetermined procedure and pressure. Due to the circumferential uniform distribution design of the receiving port and the effective function of the steel ball limiting structure 46, each press-fitting operation can be carried out efficiently and accurately. The device continuously and stably completes the assembly of a large number of steel balls and steel ball seats, and the defective rate of the product is low.

[0027] The elastic member 461 and the limit head 462 in the steel ball limit structure 46 cooperate to provide reliable limit and buffer for the steel ball during the process from steel ball feeding to press-fitting. Even if there are certain vibrations or other interference factors during the operation of the equipment, the steel ball can be stably placed in the receiving port and wait for press-fitting. This not only reduces the risk of accidental movement of the steel ball in the state of waiting for press-fitting, but also ensures the consistency of the initial position of the steel ball during press-fitting, thereby improving the stability of the press-fitting quality and reducing the scrap rate.

[0028] Further, the steel ball feeding mechanism 8 includes a material holding barrel 82, a transfer plate 81 and a third driving device 85; the material holding barrel 82 is arranged on one side of the steel ball pressing mechanism 4, and a plurality of discharge ports are arranged at the bottom of the material holding barrel 82; the transfer plate 81 is movably arranged at the bottom of the material holding barrel 82, and a plurality of bearing ports are arranged on the transfer plate 81, and the bearing ports correspond to the discharge ports; The third driving device 85 is disposed below the material holding barrel 82 , and the third driving device 85 drives the transfer plate 81 to move between the steel ball pressing mechanism 4 and the material holding barrel 82 .

[0029] Specifically, the bottom of the bottom barrel 82 is provided with 6 discharge ports, each of which has a diameter slightly larger than the steel ball, to ensure that a single steel ball can pass smoothly. The transfer plate 81 can be movably arranged at the bottom of the barrel 82 through a high-precision guide rail. The 6 bearing ports on the transfer plate 81 correspond to the discharge ports one by one. The edges of the bearing ports are specially processed and have a smooth surface to avoid scratching the steel balls. The third driving device 85 uses a high-performance linear motor, which can quickly and accurately drive the transfer plate 81 to move between the steel ball pressing mechanism 4 and the barrel 82.

[0030] Furthermore, an agitator 83 is also provided in the material holding barrel 82 , and a fourth driving device 84 is provided on the pressing main machine 100 . The output end of the fourth driving device 84 is fixedly connected to the agitator 83 , and the fourth driving device 84 drives the agitator 83 to rotate in the material holding barrel 82 .

[0031] During the production process, a large number of steel balls that meet the standards are poured into the material barrel 82. The fourth driving device 84 is started, and its output end drives the stirrer 83 to rotate at a high speed in the material barrel 82. The stirrer 83 adopts a propeller design, which can effectively stir the steel balls and prevent the steel balls from being blocked or agglomerated in the material barrel 82.

[0032] When it is necessary to load the steel balls, the third driving device 85 drives the transfer plate 81 to move so that the load port is aligned with the discharge port. At this time, under the combined action of gravity and the agitator 83, the steel balls fall from the discharge port into the load port. Subsequently, the transfer plate 81 moves the load port carrying the steel balls to above the waiting pressing positioning plate 44 of the steel ball pressing mechanism 4, and accurately delivers the steel balls into the receiving port of the waiting pressing positioning plate 44, preparing for the subsequent pressing process. During the entire production process, the steel ball feeding mechanism 8 operates continuously and stably, ensuring the continuous supply of steel balls, greatly improving the production efficiency of the steering connection components, and the product quality is stable and reliable.

[0033] The entire steel ball feeding process is automatically controlled by the third drive device 85 and the fourth drive device 84, without excessive human intervention. This not only reduces the labor intensity and error probability of manual operation, but also makes the production process more standardized and intelligent.

[0034] In a specific embodiment, the steel ball seat feeding mechanism includes a material rack 1 and a transfer mechanism 2, the material rack 1 is arranged on one side of the press-fitting main machine 100, and the transfer mechanism 2 is arranged between the material rack 1 and the press-fitting main machine 100; The material rack 1 includes a first guide rail 11 and a storage rack 13. The first guide rail 11 is provided with a first slider 12. The first slider 12 is provided with a mounting plate. The mounting plate is provided with a plurality of storage racks 13. The storage racks 13 are used to carry steel ball seats. The transfer mechanism 2 includes a conveyor line 22 and a first clamp 21. The conveyor line 22 is arranged on one side of the first guide rail 11, and the outlet end of the conveyor line 22 is arranged close to the steel ball pressing mechanism 4; the first clamp 21 is arranged at the inlet end of the conveyor line 22, and the first clamp 21 includes a first driving system 221 and a first clamping member 222. The first driving system 221 drives the first clamping member 222 to move between the first guide rail 11 and the conveyor line 22.

[0035] Specifically, the first guide rail 11 is made of high-strength aluminum alloy material and has good straightness and wear resistance. Along the first guide rail 11, at least one first slider 12 is installed, and a mounting plate is fixed on each first slider 12. On the mounting plate, multiple racks 13 are evenly distributed, for example, 4-5 racks 13 can be. These racks 13 are made of stainless steel material, and the surface is finely processed, which can effectively prevent the steel ball seat from being scratched during the placement process. Before production, workers neatly place a large number of pre-treated steel ball seats on the racks 13. The conveyor line 22 of the transfer mechanism 2 is located on one side of the first guide rail 11, and the conveyor line 22 can be operated by belt drive. At the entrance end of the conveyor line 22, a first clamp 21 is installed. The first drive system 221 uses a three-axis robot arm to control the movement of the first clamp 222. The first clamp 222 can design a clamp according to the shape of the steel ball seat to ensure that the steel ball seat can be firmly grasped.

[0036] When the automatic steel ball pressing device is started, the first driving system 221 drives the first clamping member 222 to move to the material rack 1. Through the cooperation of the preset program and the sensor, the first clamping member 222 accurately grabs the steel ball seat on the rack 13 and transfers it to the conveyor line 22. The steel ball seat moves orderly toward the exit end on the conveyor line 22, and finally approaches the steel ball pressing mechanism 4.

[0037] The design of multiple racks 13 enables the rack 1 to carry a large number of steel ball seats at one time, reducing the number of frequent loading. At the same time, the efficient operation of the transfer mechanism 2 can quickly transfer the steel ball seats from the rack 1 to the vicinity of the steel ball pressing mechanism 4, ensuring the continuous supply of steel ball seats and greatly improving the overall loading efficiency.

[0038] In addition, the rack 13 can be designed to be adjustable so as to carry the steel ball seat. The first clamping member 222 can also be adjusted and replaced according to steel ball seats of different models and sizes, so that the steel ball seat feeding mechanism has strong versatility.

[0039] Furthermore, a steel ball seat positioning mechanism 3 is provided between the outlet end of the conveying line 22 and the steel ball pressing mechanism 4; The steel ball seat positioning mechanism 3 includes a primary positioning mechanism 31 and a secondary positioning mechanism 32, wherein the primary positioning mechanism 31 is arranged on one side of the secondary positioning mechanism 32, and the primary positioning mechanism 31 is arranged close to the outlet end of the conveying line 22, and the secondary positioning mechanism 32 is arranged close to the steel ball pressing mechanism 4; The primary positioning mechanism 31 includes a first transverse movement module 313, a first workstation 311 and a second workstation 312. The first workstation 311 is close to the exit end of the conveyor line 22, and the second workstation 312 is arranged close to the secondary positioning mechanism 32. The first workstation 311 is used to carry the incoming materials of the conveyor line 22; the second workstation 312 is provided with a bearing block and a rotating drive device, the bearing block is used to carry the steel ball seat, and the rotating drive device drives the bearing block to rotate; the first workstation 311 and the second workstation 312 are both provided with photoelectric sensors for detecting the steel ball seat; the photoelectric sensor in the second workstation 312 is used to detect the position of the preset hole position on the steel ball seat. When the preset hole position on the steel ball seat is opposite to the photoelectric sensor in the second workstation 312, it indicates that the steel ball seat is preliminarily positioned on the second workstation 312.

[0040] A first transverse moving clamp 314 is provided on the first transverse moving module 313, and the first transverse moving clamp 314 includes a connecting plate 3142 and two first transverse moving clamps 3141. The connecting plate 3142 is fixed on the first transverse moving module 313, and the two first transverse moving clamps 3141 are both provided on the connecting plate 3142, and the axes of the two first transverse moving clamps 3141 are parallel to each other.

[0041] In actual production, the steel ball seat is continuously transported through the conveyor line 22. When the steel ball seat reaches the exit end of the conveyor line 22, it first enters the first station 311 of the primary positioning mechanism 31. The photoelectric sensor on the first station 311 detects the steel ball seat to confirm the arrival of the steel ball seat. At this time, the first transverse movement clamp 314 on the first transverse movement module 313 is started under the command of the control system. The connecting plate 3142 drives the two first transverse movement clamps 3141 to accurately clamp the steel ball seat and smoothly transfer it to the second station 312.

[0042] The two first transverse moving clamps 3141 on the first transverse moving clamp 314 can flexibly transport the steel ball seat between different workstations, thereby improving production efficiency.

[0043] At the second station 312, the bearing block holds the steel ball seat steadily, and the rotation drive device starts to work. The rotation drive device can use a high-precision servo motor, which can accurately control the rotation angle of the bearing block. As the bearing block rotates slowly, the preset hole position on the steel ball seat gradually approaches the photoelectric sensor. When the photoelectric sensor detects that the hole position is relative to itself, it means that the steel ball seat has achieved preliminary positioning on the second station 312. Then, the steel ball seat after preliminary positioning is further conveyed to the secondary positioning mechanism 32. The secondary positioning mechanism 32 accurately positions the steel ball seat to ensure that the steel ball seat is accurately positioned when entering the steel ball pressing mechanism 4, thereby ensuring the accuracy of the installation.

[0044] Furthermore, the secondary positioning mechanism 32 includes a second transverse shift module 321, one end of the first transverse shift module 313 extends to one end of the first transverse shift module 313, and the other opposite end extends to the steel ball pressing mechanism 4; the second transverse shift module 321 is provided with a pin fixture 323 and a fifth driving device 322, the fifth driving device 322 is arranged on the second transverse shift module 321, the pin fixture 323 is fixed to the output end of the fifth driving device 322, and a plurality of pins are arranged on the pin fixture 323, and the pins correspond to the through holes of the steel ball seat.

[0045] In the actual production process, after the steel ball seat is initially positioned by the primary positioning mechanism 31, the first transverse moving module 313 and the first transverse moving fixture 314 send the steel ball seat to the secondary positioning mechanism 32. Specifically, the first transverse moving fixture 314 transports the steel ball seat in the second station 312, and at the same time, the second transverse moving module 321 and the fifth driving device 322 are started, so that the ejector fixture 323 moves toward the second station 312, and at the same time, the ejector fixture 323 moves upward. Several ejectors on the ejector fixture 323 are adapted to the through holes of the steel ball seat. On the basis of the primary positioning, the ejector is accurately inserted into the through hole of the steel ball seat, further fixing the position of the steel ball seat to ensure that it will not be displaced or deviated when entering the steel ball press-fitting mechanism 4.

[0046] Due to the reliable function of the secondary positioning mechanism 32, each steel ball seat can be accurately positioned in the same standard position before entering the press-fitting stage, ensuring the consistency of the product during mass production. Whether in the short-term or long-term production process, the quality of the product can remain stable, reducing product performance fluctuations caused by assembly differences.

[0047] More specifically, after the ejector fixture 323 is fixed with the steel ball seat, it enters the steel ball press-fitting mechanism 4 under the drive of the second transverse module 321. At this time, the first driving device 42 drives the positioning plate 44 to be pressed to move downward, so that the positioning plate 44 to be pressed is pressed down and fits tightly with the steel ball seat, ensuring that the steel ball seat will not be displaced during the press-fitting process. And each steel ball on the positioning plate 44 to be pressed corresponds to a through hole on the steel ball seat. Then the second driving device 43 drives the press-fitting module 45 to move downward, and the multiple press-fitting heads 451 on the press-fitting module 45 simultaneously apply sufficient pressure to the steel balls in the corresponding receiving ports to steadily press the steel balls into the through holes of the steel ball seat.

[0048] Furthermore, it also includes a leak detection mechanism 5, which is arranged on one side of the steel ball pressing mechanism 4, and includes a clamping claw cylinder 53, a leak detection device 52 and a second driving system 51, and the second driving system 51 is arranged on one side of the steel ball pressing mechanism 4, and the clamping claw cylinder 53 is fixed at the output end of the second driving system 51, and the clamping claw cylinder 53 includes two openable and closable clamping plates; The leak detection device 52 includes a leak detection mounting plate 521 and a plurality of detection heads 522. The leak detection mounting plate 521 is fixed to the output end of the second driving system 51, and the clamping claw cylinder 53 is fixed to the middle of the leak detection mounting plate 521; the plurality of detection heads 522 are all fixed to the leak detection mounting plate 521 and are located at the periphery of the clamping claw cylinder 53; A photoelectric sensor is also provided below the leak detection mechanism 5. The photoelectric sensor below the leak detection mechanism 5 is used to detect whether a steel ball seat after press-fitting of steel balls is sent to the leak detection mechanism 5.

[0049] On the production line, after the steel ball is pressed, it can be driven by the second lateral movement module 321 to allow the ejector fixture 323 to enter the leak detection mechanism 5. When a steel ball seat is transported to the bottom of the leak detection mechanism 5, the photoelectric sensor immediately detects its presence and sends a signal to the control system. Subsequently, the second drive system 51 is started, driving the clamping cylinder 53 and the leak detection device 52 to descend to a suitable position. The two clamping plates of the clamping cylinder 53 are opened to firmly clamp the steel ball seat to ensure that the steel ball seat will not be displaced during the detection process.

[0050] At this time, multiple detection heads 522 located on the periphery of the clamping jaw cylinder 53 start to work. These detection heads 522 can use electromagnetic induction technology to accurately detect whether a steel ball is pressed into the through hole of the steel ball seat. The detection head 522 uses a contact sensor to detect whether a steel ball is pressed into the through hole. When the detection head 522 feedbacks that ≥1 steel ball is not sensed, it proves that there is a missing installation, and the clamping jaw cylinder 53 opens to put the workpiece into the defective product area. If steel balls are detected, the second drive system 51 drives the workpiece to move and put the workpiece into the qualified product area.

[0051] In a more preferred embodiment, when the detection head 522 fails to detect a qualified workpiece three times in a row, it is determined that there is a shortage of steel balls, and the system alarm prompts to replenish the steel ball material.

[0052] More preferably, it also includes a first collecting device 6 and a second collecting device 7, each of which includes a collecting channel 62 and a collecting box 61, and one end of the collecting channel 62 of the two collecting devices is arranged below the leak detection mechanism 5, and the other end extends to the collecting box 61.

[0053] During the production process, after the steel ball seat is tested by the steel ball press-fitting and leak detection mechanism 5, it is classified and collected according to the test results. If the steel ball seat is detected as a qualified product, the second driving system 51 will move the clamping claw cylinder 53 to a suitable position so that the qualified steel ball seat is aligned with the entrance of the collection channel 62 of the second collection device 7. The clamping claw cylinder 53 releases the clamping plate, and the steel ball seat slides smoothly along the collection channel 62 into the collection box 61 of the second collection device 7 under gravity or slight push.

[0054] When it is detected that the steel ball seat has a non-conforming condition such as a steel ball press-fitting problem (such as a steel ball missing), the gripper cylinder 53 will move the non-conforming product to the top of the collecting channel 62 of the first collecting device 6, and then release the non-conforming product to enter the collecting box 61 of the first collecting device 6. For example, in a continuous production operation, after several hours of operation, the first collecting device 6 collects a certain number of non-conforming steel ball seats, and these non-conforming products are clearly separated from the qualified products to avoid confusion.

[0055] The classified and collected products are convenient for subsequent processing and statistics. For unqualified products, they can be reworked or analyzed in a centralized manner, reducing the time and energy of finding and handling unqualified products on the production line. For qualified products, they can smoothly enter the next process or packaging link, making the entire production process smoother and improving the production management efficiency of the workshop.

[0056] Example 2 like Figure 1-Figure 3 As shown, this embodiment provides a method for automatic press-fitting of steel balls, which is implemented based on the automatic press-fitting device for steel balls as described above.

[0057] Specifically, the method comprises the following steps: The steel balls and the steel ball seats are placed on the corresponding steel ball feeding mechanism 8 and the rack 13 of the steel ball seat feeding mechanism. Ensure that the number of steel balls and steel ball seats is sufficient and meets the specifications required by production.

[0058] The steel ball seat feeding mechanism is started, and the first slider 12 on the first guide rail 11 of the material rack 1 drives the mounting plate to move, so that the steel ball seat on the storage rack 13 is in a position convenient for the transfer mechanism 2 to grab. The first clamp 21 of the transfer mechanism 2 is driven by the first drive system 221, and the first clamp 222 accurately clamps the steel ball seat and places it at the entrance end of the conveyor line 22. The steel ball seat then moves toward the exit end on the conveyor line 22, and when it reaches the steel ball seat positioning mechanism 3 between the exit end and the steel ball pressing mechanism 4, it enters the first station 311 of the primary positioning mechanism 31.

[0059] At this time, the photoelectric sensor of the first station 311 detects the arrival of the steel ball seat and transmits a signal to the control system. Under the command of the control system, the first transverse moving fixture 314 on the first transverse moving module 313 drives the two first transverse moving clamps 3141 with the connecting plate 3142 to smoothly transfer the steel ball seat to the second station 312. At the second station 312, the bearing block bears the steel ball seat, and the rotating drive device drives the bearing block to rotate slowly. When the preset hole position on the steel ball seat is opposite to the photoelectric sensor in the second station 312, the preliminary positioning is achieved.

[0060] The steel ball seat after the initial positioning is then transported to the secondary positioning mechanism 32. The fifth driving device 322 on the second transverse module 321 drives the ejector fixture 323 to move, so that the ejector is accurately inserted into the through hole of the steel ball seat, completing the secondary precise positioning. Then the second transverse module 321 sends the steel ball seat after the secondary positioning into the steel ball pressing mechanism 4.

[0061] At the same time, the stirrer 83 in the material holding barrel 82 of the steel ball feeding mechanism 8 starts to rotate under the drive of the fourth driving device 84 to prevent the steel ball from being blocked. The steel ball falls from the discharge port at the bottom of the material holding barrel 82 into the bearing port of the transfer plate 81. The third driving device 85 drives the transfer plate 81 to move the steel ball to the top of the waiting pressing positioning plate 44 of the steel ball pressing mechanism 4. The steel ball enters the receiving port of the waiting pressing positioning plate 44 and is fixed in position by the steel ball limiting structure 46 (elastic member 461 and limiting head 462) on one side of the receiving port.

[0062] When the steel ball seat and the steel ball are ready, the first driving device 42 on the press-fitting frame 41 drives the positioning plate 44 to move downward to make it fit tightly with the steel ball seat. Then, the second driving device 43 drives the press-fitting module 45 to move downward, and the multiple press-fitting heads 451 on the press-fitting module 45 accurately press the steel balls into the corresponding holes of the steel ball seat.

[0063] After the press-fitting is completed, the steel ball seat is transported to the bottom of the leak detection mechanism 5. The photoelectric sensor under the leak detection mechanism 5 detects the presence of the steel ball seat and sends a signal to the second drive system 51. The second drive system 51 drives the clamping cylinder 53 and the leak detection device 52 to descend, and the two clamping plates of the clamping cylinder 53 clamp the steel ball seat. Multiple detection heads 522 located on the periphery of the clamping cylinder 53 detect the steel ball seat to determine whether the steel ball has problems such as pressure leakage or inaccurate press-fitting position.

[0064] If the test result is qualified, the second drive system 51 moves the clamping cylinder 53 to above the entrance of the collection channel 62 of the second collection device 7, the clamping cylinder 53 releases the clamping plate, and the steel ball seat enters the collection box 61 of the second collection device 7 along the collection channel 62 to be collected as qualified products. If unqualified is detected, the second drive system 51 moves the clamping cylinder 53 to above the entrance of the collection channel 62 of the first collection device 6, so that the unqualified products enter the collection box 61 of the first collection device 6 for subsequent rework or analysis.
