Description

Technical Field

[0001] The present invention belongs to the technical field of dishwasher basket processing equipment, and more particularly relates to an automatic assembly device for upper and lower basket and dish racks of a dishwasher. Background Art

[0002] With the advancement of technology and the improvement of living standards, especially the rapid development of home appliances, specialized dishwashing equipment has emerged for cleaning dishes. A multifunctional dishwasher typically features spraying, drying, and sterilizing functions. Users simply place dishes and other tableware into the dishwasher, which automatically completes a series of cleaning tasks based on user settings. Its ease of use and fully automated operation effectively reduces user effort. As a result, dishwashers are becoming increasingly popular in countless households and are deeply loved by users.

[0003] The dish rack is a crucial component in dishwashers. Installed within the dish basket, it supports and secures bowls and plates, keeping them stable during the wash cycle. It also ensures that wash water and detergent fully contact the surfaces of the bowls and plates, ensuring a thorough clean. Traditional dishwashing racks are welded manually, which can lead to drawbacks such as insufficient weld strength, high labor intensity, high labor costs, unsightly appearance, and low welding efficiency.

[0004] To address the above-mentioned issues, a series of automatic welding equipment has emerged on the market to reduce the workload during dishwashing basket welding, improve work efficiency, and enhance aesthetics. For example, patent CN214769822U discloses an automatic welding device for assembling and welding dishwashing basket parts. During welding, the dishwashing basket to be welded is placed on a clamping fixture, and then a driving device drives the clamping fixture to move toward a welding station. The welding device then welds the dishwashing basket on the clamping fixture at the welding station. Once welding is complete, the driving device drives the clamping fixture and the welded dishwashing basket to a side away from the welding station for removal. This utility model can reduce manual labor intensity, improve welding efficiency, and ensure product welding quality.

[0005] Patent CN116021214A discloses a multi-point rapid welding platform for dishwasher baskets. This application utilizes a clamping assembly to hold the metal rods that make up the basket. Two main metal rods are interlaced and clamped within two metal arc-shaped clamps, straightening the rods and facilitating position adjustment. The weld position of the basket, made of metal rods, can be controlled at any time, facilitating operation, enabling the production of different baskets, and facilitating installation and removal.

[0006] Patent CN115958365A discloses a clamping-free, quick-alignment and welding fixture for dishwasher baskets. This application utilizes a retaining bracket that is clamped within a fixed slot, allowing the steel rod to be secured to the retaining bracket. With a tapered shaft inserted within an L-shaped plate, the tapered shaft compresses one end of the movable shaft, causing the movable shaft to move and rest against the surface of the steel rod. This enhances the retaining effect, ensures the stability of the entire steel rod, and reduces displacement and errors during welding.

[0007] Patent CN217224200U discloses a welding device for bowl and basket welding. The application is provided with multiple upper welding heads and multiple lower welding heads that cooperate with each other. When welding, when the supporting fixture is pushed and moved along the guide rail to the welding station, the upper welding heads and the lower welding heads cooperate to simultaneously weld multiple intersection points of the rods. The structure is simple, which is conducive to reducing the labor intensity of workers, shortening the working time and improving the welding efficiency.

[0008] Patent CN115740865A discloses a turntable automatic bowl and basket welding machine and its operating method. This application is used in conjunction with sensors, clamps and telescopic rods to position and load bowls and baskets. The rotating structure is used in conjunction with the ejection mechanism to eject the welded bowls and baskets and insert new bowls and baskets to be welded simultaneously, thereby saving manual handling time and waiting time during continuous work, and improving production efficiency.

[0009] The aforementioned applications all involve improvements to automated welding and assembly technology for bowl baskets, effectively improving welding efficiency and quality. However, control of welding quality primarily focuses on securing the bowl basket and its accessories. They fail to address the issue of deformation of the basket rack caused by welding stress during the welding process, which can affect the final quality and appearance of the basket. Summary of the Invention

[0010] 1. Problems to be solved

[0011] In response to at least some of the problems existing in the above-mentioned prior art, the present invention proposes an automated assembly device for upper and lower bowl baskets and dish racks of a dishwasher.

[0020] Furthermore, the automated assembly device also includes a rotating table, on which is provided a first positioning fixture for accommodating the crossbeam of the disc rack and the stirrup head. Driven by the rotating table, the first positioning fixture passes through the workstations where the welding equipment and the shaping mechanism are located in sequence.

[0021] Furthermore, the automated assembly device further comprises a loading platform, on which a first loading mechanism for placing the beam in the first positioning fixture is provided;

[0022] The first feeding mechanism includes a feeding box and a guide plate obliquely arranged in the feeding box; a gap is left between the lower end of the guide plate and the inner end wall of the feeding box, and a push plate that can move up and down is provided in the gap. The push plate is used to push a single beam out of the feeding box and transfer it to the first positioning fixture by the robot.

[0023] Furthermore, an escape space for placing the bent section of the beam is formed between one side of the guide plate and the inner side wall of the loading box, and the escape space extends all the way to the position of the push plate.

[0024] Furthermore, the top surface of the end of the loading box close to the push plate is an inclined surface, and the inclined surface is provided with stop blocks distributed at intervals. The inclined surface and the stop blocks jointly support and limit the main part of the beam.

[0025] Furthermore, an adjusting rod is provided on the side of the loading box, which is eccentrically connected to the output shaft of the rotating motor and is used to drive the bending section of the beam to rotate to the position of the limit rod to adjust the posture of the bending section.

[0026] Furthermore, the loading platform is provided with a second loading mechanism for placing the stirrup head piece in the first positioning fixture;

[0027] The second feeding mechanism includes a vibrating plate and a first sorting mechanism; wherein the first sorting mechanism is arranged at the discharge port of the vibrating plate, and includes a pair of first baffles arranged opposite to each other, and a first slideway is formed between the two first baffles;

[0028] The width of the first slideway is larger than the rod diameter of the stirrup head and smaller than the ball diameter of the stirrup head, so that the rod body of the stirrup head can be accommodated in the first slideway, and the ball head of the stirrup head is located outside the first slideway.

[0029] 3. Beneficial effects

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) The present invention provides an automated assembly device for upper and lower bowl baskets and dish racks of a dishwasher. After the dish racks are welded, a robot transfers the welded dish racks to the limiting grooves of a bracket. Then, a pressing portion presses and limits the dish racks. Finally, a shaping block squeezes the dish racks to correct the deformation of the dish racks, thereby improving the deformation amount of the dish racks and enhancing their flatness, thereby facilitating the final quality and appearance of the bowl baskets.

[0032] (2) The automatic assembly device for the upper and lower bowl baskets and dish racks of a dishwasher of the present invention can enable the first positioning fixture to be freely switched between different workstations by setting a rotating table, which is conducive to ensuring the continuity of production.

[0033] (3) The present invention provides an automatic assembly device for upper and lower bowl baskets and dish racks of a dishwasher. By setting up a first loading mechanism and utilizing the reciprocating lifting and lowering operation of a push plate, the beam can be transported individually and continuously. At the same time, by the mutual cooperation of the inclined surface and the stop block, the individually transported beam can be supported and limited to facilitate the subsequent grabbing and transferring operation of the beam.

[0034] (4) The present invention provides an automatic assembly device for the upper and lower bowl baskets and plate racks of a dishwasher. By means of the mutual cooperation between the adjusting rod and the limiting rod, the bending section of the beam is rotated to a suitable position by the rotation of the adjusting rod, so that each beam can be kept in the same posture, which is beneficial to the subsequent welding operation.

[0035] (5) The present invention provides an automatic assembly device for upper and lower bowl baskets and dish racks of a dishwasher. By setting a first sorting mechanism, a first slide is formed between two first baffles, and the width of the first slide is larger than the rod diameter of the stirrup head and smaller than the ball head diameter of the stirrup head. Therefore, the stirrup heads coming out of the vibrating plate outlet can be arranged in the same direction with the ball heads facing upwards, whether in the forward or reverse direction, thereby providing a basis for subsequent loading operations.

[0036] (6) The present invention provides an automatic assembly device for upper and lower bowl baskets and dish racks of a dishwasher. By setting a second sorting mechanism, the width of the second slide can be controlled to perform online identification and stop of stirrup head parts with poor straightness, so that they cannot pass through the second slide smoothly and are removed, which is beneficial to ensuring the quality and appearance of the final product.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] The dish rack 7 is an important component in the dishwasher, which is assembled in the bowl basket body. Its function is to support and fix the bowls and plates so that they can maintain a stable position during the washing process. The specific structure of the dish rack 7 is as follows Figure 11 As shown, it includes a crossbeam 71 and a stirrup head 72. The crossbeam 71 includes a main body and a bent section at the end of the main body, and the main body and the bent section are actually a rod; the stirrup head 72 includes a rod body and a ball head at the end of the rod body. The stirrup head 72 is evenly spaced and parallel along the axial direction of the main body of the crossbeam 71.

[0056] The present invention will be further described below with reference to specific embodiments.

[0057] like Figure 1 、 Figure 2As shown, this embodiment of an automated assembly device for upper and lower basket racks of a dishwasher includes a rotating platform 1, a welding device 2, and a shaping mechanism 3. A first positioning fixture 11 is provided on the rotating platform 1 for limiting the position of a crossbeam 71 and a stirrup 72. This first positioning fixture 11 is provided with receiving slots for the crossbeam 71 and stirrup 72 to engage. The arrangement of these slots aligns with the arrangement of the crossbeam 71 and stirrup 72 of the rack 7, enabling pre-assembly of the rack 7.

[0058] Simultaneously, the first positioning jig 11, driven by the rotating table 1, sequentially passes through the stations housing the welding equipment 2 and the shaping mechanism 3. The welding station is equipped with the welding equipment 2, which is used to weld the crossbeam 71 and stirrup head 72 within the first positioning jig 11 to achieve a secure connection. The shaping mechanism 3 is equipped at the shaping station to shape the disc frame 7 after welding to mitigate deformation caused by welding stress.

[0059] It should be noted that, in this embodiment, the welding device 2 can be a device in the prior art, and its structure and working principle are also in the prior art, which will not be described in detail here. The shaping mechanism 3 is the focus of this article and will be described in detail below.

[0060] refer to Figure 3 As shown, the shaping mechanism 3 includes a bracket 31 with a support platform mounted thereon. The support platform is provided with a retaining groove 32 for accommodating the disk rack 7. Both ends of the retaining groove 32 are provided with pressing portions 33 for compressing and retaining the ends of the disk rack 7 within the retaining groove 32. Furthermore, a shaping block 34 is mounted on the bracket 31. Driven by a power source 35, the shaping block 34 compresses and shapes the disk rack 7.

[0061] The shaping block 34 can be positioned at the bottom and / or side of the limiting groove 32 to perform extrusion and shaping from the bottom and / or side of the rack 7. The specific location of the shaping block 34 can be adjusted based on the actual deformation of the rack 7. To ensure the stability of the shaping block 34 during movement, the shaping block 34 is also equipped with a guide rail 36.

[0062] During the actual welding process, the stirrup head 72 is relatively short and has a relatively small number of weld points. Therefore, the stirrup head 72 does not deform significantly. However, the crossbeam 71 is relatively long and has a relatively large number of weld points. Therefore, the crossbeam 71 will deform significantly after welding. Therefore, in this embodiment, the shaping block 34 primarily compresses the main portion of the crossbeam 71.

[0063] Specifically in this embodiment, the power source 35 can be any one of an air cylinder, an oil cylinder or an electric push rod. Simultaneously, the pressing portion 33 is connected to a rotary pressing cylinder to drive it to press the rack 7 downward.

[0064] In addition, in order to facilitate the transfer of the welded disc rack 7 from the first positioning fixture 11 on the rotating table 1 to the limiting groove 32 of the shaping mechanism 3, and to facilitate the removal of the shaped disc rack 7 from the limiting groove 32 and transfer to the next process, in this embodiment, a clamping member 37 is provided on the bracket 31, and the clamping member 37 can be a conventional robot.

[0065] In this embodiment, an automated assembly device for upper and lower basket racks of a dishwasher is provided. After the rack 7 is welded, a robot transfers the welded rack 7 to a limiting groove 32 on a bracket 31. The pressing portion 33 then compresses and limits the rack 7. Finally, the shaping block 34 squeezes the rack 7 to correct its deformation, thereby improving the deformation of the rack 7 and enhancing its flatness, thereby facilitating the final quality and appearance of the basket.

[0066] To further facilitate the smooth transfer of the crossbeam 71 and stirrup 72 into the receiving slot of the first positioning jig 11 and complete the automatic loading operation of the crossbeam 71 and stirrup 72, in this embodiment, a loading platform 4 is provided on one side of the rotating table 1. The loading platform 4 is equipped with a first loading mechanism 5 and a second loading mechanism 6. The first loading mechanism 5 is used to place the crossbeam 71 into the first positioning jig 11, and the second loading mechanism 6 is used to place the stirrup 72 into the first positioning jig 11.

[0067] Specifically, in this embodiment, four first positioning jigs 11 are installed on the rotating table 1. Driven by the rotating table 1, each first positioning jig 11 sequentially passes through the workstations where the first loading mechanism 5, the second loading mechanism 6, the welding equipment 2, and the shaping mechanism 3 are located, completing the loading, welding, and shaping process in an integrated manner. Furthermore, the presence of four first positioning jigs 11 allows operations at each workstation to be performed synchronously, thereby improving production efficiency.

[0068] refer to Figure 4 As shown in FIG. 1 , as one embodiment of the first loading mechanism 5 , it includes a loading box 51 , within which is disposed an inclined guide plate 52 . A gap is formed between the lower end of the guide plate 52 and the inner end wall of the loading box 51 . A reciprocating push plate 53 is disposed within this gap. This push plate 53 is used to eject a single crossbeam 71 from the loading box 51 , allowing the robot to grasp or absorb the beam into the first positioning fixture 11 .

[0069] Of course, the push plate 53 needs to be connected to a driving source that drives it to move up and down. The driving source can be an air cylinder, an oil cylinder, an electric push rod or other existing equipment with a contraction function.

[0070] At the same time, a clearance space 54 is formed between one side of the guide plate 52 and the inner sidewall of the loading box 51 to accommodate the bent sections of the crossbeam 71. This clearance space 54 extends all the way to the location of the push plate 53, and the end of the push plate 53 does not extend into the clearance space 54. The provision of this clearance space 54 allows the bent sections of the crossbeam 71 to sag naturally under the action of gravity, preventing interference between the bent sections of the crossbeam 71 during the lifting process.

[0071] As a preferred embodiment of the first feeding mechanism 5, refer to Figure 5 、 Figure 6 As shown, the top surface of the loading box 51 near the push plate 53 is an inclined surface with a stopper 55 installed on it. The stopper 55 is spaced apart to provide sufficient gripping space for the robot. Furthermore, a notch is provided on the inclined surface to allow the bent section of the crossbeam 71 to fall freely.

[0072] That is, after the crossbeam 71 is pushed out by the push plate 53, the crossbeam 71 slides along the inclined surface to the stop block 55. At this time, the inclined surface and the stop block 55 jointly support and limit the main part of the crossbeam 71, while the bent section of the crossbeam 71 is located in the notch reserved by the inclined surface and is in a free hanging state.

[0073] During the loading process of the crossbeam 71, certain requirements are placed on the orientation of the bent section. To address this, in this embodiment, a rotary motor is installed on the side of the loading box 51 near the escape space 54. An adjustment rod 56 is eccentrically connected to the output end of the rotary motor. Furthermore, a stop rod 57 is positioned within a recessed opening on the inclined surface. Driven by the motor, the adjustment rod 56 rotates a certain angle, which in turn drives the crossbeam 71 through the bent section, ultimately causing the bent section to rest against the stop rod 57, ensuring that the orientation of the bent section meets the requirements for subsequent welding.

[0074] The present embodiment provides an automatic welding device for dishwasher dish racks. Through the provision of a first feeding mechanism 5, the reciprocating lifting and lowering operation of the push plate 53 can be used to transport the beam 71 individually and continuously. At the same time, through the mutual cooperation of the inclined surface and the stop block 55, the individually transported beam 71 can be supported and limited to facilitate the subsequent grabbing and transferring operation of the beam 71. In addition, through the mutual cooperation of the adjusting rod 56 and the limiting rod 57, the turning section of each beam 71 can be kept in the same posture, which is beneficial to the subsequent welding operation.

[0075] In this embodiment, as an implementation of the second feeding mechanism 6, refer to Figure 2 As shown, the second feeding mechanism 6 includes a vibration plate 61 and a first sorting mechanism 62. The vibration plate 61 is used to output the stirrup head pieces 72 one by one; the first sorting mechanism 62 is used to receive the stirrup head pieces 72 output by the vibration plate 61 and sort the stirrup head pieces 72 in the same direction and in sequence to meet the subsequent assembly requirements.

[0076] It should be noted that, in this embodiment, the vibration plate 61 can be a device in the prior art, and its structure and working principle are also in the prior art and are not described in detail here. The first sorting mechanism 62 is the focus of this article and will be described in detail below.

[0077] refer to Figure 7 As shown, the first sorting mechanism 62 is primarily composed of two first baffles 621 arranged in parallel with each other. A first slideway 622 is formed between the two first baffles 621. The width of the first slideway 622 (i.e., the distance between the two first baffles) is greater than the diameter of the stirrup head 72 but smaller than the diameter of the ball head of the stirrup head 72. This allows the stirrup head 72 to fit within the first slideway 622, while the ball head of the stirrup head 72 is located outside the first slideway 622 and supported by the top of the first baffle 621. This ensures that the stirrup heads 72 entering the first slideway 622 are all arranged one by one with their ball heads facing upward.

[0078] The second feeding mechanism (6) of this embodiment, through the provision of the first slideway 622, enables the stirrup head pieces 72 exiting the discharge port of the vibration disk 61 to ultimately present the same direction with the ball head facing upwards and be arranged in sequence, whether in the forward or reverse direction, thereby providing a good foundation for subsequent operations and making the connection between processes smoother. The forward direction here refers to the ball head portion of the stirrup head piece 72 leaving the discharge port of the vibration disk 61 first; and the reverse direction refers to the rod portion of the stirrup head piece 72 leaving the discharge port of the vibration disk 61 first.

[0079] It's also worth noting that the ball head diameters mentioned above refer to those within the standard range, i.e., those that meet the requirements. However, for balls with diameters that are too small and don't meet the requirements, the width of the first slideway 622 can be controlled. Specifically, the width of the first slideway 622 is set to be larger than the diameters of balls with smaller diameters (determined based on actual production requirements), but smaller than the diameters within the standard range. This design allows small balls that don't meet the requirements to fall directly from the first slideway 622, thereby automatically screening out defective stirrup head components 72 and ensuring the overall quality and appearance of the assembled product.

[0080] In this embodiment, as a specific implementation of the first baffle 621, the first baffle 621 is tilted as a whole to facilitate the stirrup head 72 to slide along the first slide 622 to the discharge port of the first sorting mechanism 62 under the action of its own gravity.

[0081] Specifically, the first baffle 621 includes an inclined section, an arc-shaped transition section, and a horizontal section connected in sequence. The end of the inclined section away from the horizontal section is the feed port, and the end of the horizontal section away from the inclined section is the discharge port. To facilitate the entry of the stirrup head 72 into the first slide 622, an inclined surface is provided on the inner side of the feed port end of the first baffle 621 (on the opposite side of the two first baffles), and a guide groove 623 is formed between the inclined surfaces of the two first baffles 621. The guide groove 623 is provided at the discharge port of the vibration disk 61 so that the stirrup head 72, after being sorted by the vibration disk 61, can enter the first slide 622 more smoothly.

[0082] As a preferred implementation of the first sorting mechanism 62, a clamping assembly 624 is provided near the discharge port end of the first baffle 621. The clamping assembly 624 is used to squeeze from the outside of the first baffle 621, so that the ends of the two first baffles 621 approach each other and clamp the rod body of the stirrup head 72, thereby preventing the stirrup head 72 from automatically sliding off the first slide 622 and affecting subsequent operations.

[0083] refer to Figure 8 As shown, the pressing assembly 624 includes an elastic member 6241, a first connecting block 6242, and a second connecting block 6243. The first connecting block 6242 and the second connecting block 6243 are disposed on the same outer side wall of the first baffle 621, and a notch is defined on the side of the first connecting block 6242 adjacent to the first baffle 621, and the second connecting block 6243 is located within the notch.

[0084] The elastic member 6241 is compressed between the inner wall of the notch and the outer wall of the second connecting block 6243. Preferably, the elastic member 6241 can be a compression spring. The compression spring applies an inward elastic force to the end of the first baffle 621 through the second connecting block 6243, causing the first baffle 621 to deform and move closer together, thereby clamping the rod of the stirrup head 72 and preventing the stirrup head 72 from sliding off the first slide 622.

[0085] Of course, the first slide 622 can also be designed with a variable diameter to ensure that the stirrup head 72 can be clamped at the discharge end of the first slide 622. However, it should be noted that whether the clamping assembly 624 or the variable diameter method is used, it is only to prevent the stirrup head 72 from naturally sliding out of the first slide 622, and does not completely restrict the movement of the stirrup head 72. In other words, the stirrup head 72 can be restricted from sliding out freely at the discharge end of the first slide 622, while also ensuring that the stirrup head 72 can be removed under the action of external force.

[0086] In this embodiment, a clamping claw 625, such as a robot, is provided at the discharge end of the first sorting mechanism 62. This robot is used to remove the stirrup head member 72 from the first slide 622 and transfer it to the next process. To prevent interference between the clamping claw 625 and the first baffle 621 when clamping the stirrup head member 72 in the first slide 622, a clearance groove 6211 is provided near the discharge end of the first baffle 621 for the clamping claw 625 to extend into.

[0087] Preferably, the avoidance groove 6211 is opened at the middle position of the first baffle 621, thereby dividing the end of the first baffle 621 into two parts, an upper and a lower part, so that the rod body part of the stirrup head piece 72 is respectively stuck in the first slide 622 of the upper and lower parts to prevent the bottom of the stirrup head piece 72 from swinging, which is not conducive to the clamping operation of the clamp 625.

[0088] At the same time, due to the presence of the avoidance groove 6211, the height of the corresponding side wall of the first baffle 621 becomes relatively small. At this time, the pressing assembly 624 is arranged on the smaller outer side wall of the first baffle 621, which is conducive to the extrusion deformation operation of this part.

[0089] As a preferred embodiment of the second feeding mechanism 6 , a second sorting mechanism 63 is further provided on the feeding platform 4 . The second sorting mechanism 63 is used to receive the stirrup head pieces 72 transferred from the first sorting mechanism 62 and screen the straightness of the stirrup head pieces 72 .

[0090] Specifically, refer to Figure 9 As shown, the second sorting mechanism 63 is entirely located below the clamping jaw 625 and comprises two vertically arranged second baffles 631. A second slideway 632 is formed between the two second baffles 631. The width of the second slideway 632 (the distance between the two second baffles) is slightly larger than the diameter of the stirrup head 72. By controlling the width of the second slideway 632, stirrup heads 72 with poor straightness can be identified and stopped online, preventing them from smoothly passing through the second slideway 632 and being rejected, thereby helping to ensure the quality and appearance of the final product.

[0091] In addition, a second positioning fixture 64 is provided on the loading platform 4 for receiving the stirrup head 72 transferred from the second sorting mechanism 63. Figure 10 As shown, the second positioning fixture 64 is positioned near the discharge port of the second sorting mechanism 63 and is provided with a plurality of equally spaced and parallel positioning slots 641. The stirrups 72 in the second sorting mechanism 63 are transferred to the corresponding positioning slots 641 by a robot, ensuring that the stirrups 72 are equally spaced and arranged in parallel, thus meeting the requirements of subsequent assembly.

[0092] Preferably, the positioning groove 641 is a contoured groove that matches the shape of the stirrup head 72. The second positioning jig 64 can be slidably mounted on the loading platform 4 via a slide 65 to facilitate its transfer between different workstations. Finally, a robotic arm transfers the neatly arranged stirrup head 72 within the second positioning jig 64 to the first positioning jig 11, where it is pre-assembled with the crossbeam 71 within the first positioning jig 11.

[0093] At the same time, in order to prevent material shortage in the positioning groove 641, which may cause defects during the subsequent product assembly, in this embodiment, a sensor is provided on the side of the positioning groove 641 to detect whether there is material shortage in the positioning groove 641. Of course, sensors can also be provided on the second baffle 631 and the first baffle 621 to monitor the stirrup head member 72 in their respective slideways.

[0094] In the present embodiment, an automatic assembly device for upper and lower bowl baskets and dish racks of a dishwasher is provided. By setting a second feeding mechanism 6, the stirrups can be sorted one by one and in the same direction using the first slide 622; and the stirrups 72 with poor straightness can be screened using the second slide 632.

[0095] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
