[0072] The material dividing device includes a material picking mechanism 601, a good product conveying track 602 for placing good products, a defective product conveying bin 603 for placing defective products, and a material picking driving unit capable of driving the material picking mechanism to translate along the Y direction.

[0073] like Figure 6 to Figure 7 As shown, the circulation conveying line includes a first conveying track 10 and a second conveying track 20 which are parallel to each other and used to convey the carrier 100, as well as a connecting track 302 and a connecting platform 4032 which can connect the first conveying track and the second conveying track, and the press is located at the press-fitting position of the second conveying track;

[0074] The first conveying track is provided with a sprocket chain transmission structure (this is the prior art and will not be described in detail, that is, the chain is driven to reciprocate by the motor 503 and the sprocket) and a limiting structure 501, the position of the carrier relative to the chain is limited by the limiting structure, and the carrier is driven to be conveyed by the sprocket chain transmission structure;

[0075] The second conveying track is provided with a belt conveying structure (this is a prior art and will not be described in detail, that is, the belt is driven to reciprocate through the cooperation of the motor 503 and the master and slave wheels) and a limiting mechanism 502, the position of the carrier relative to the belt is limited by the limiting mechanism, and the carrier is driven to be conveyed through the belt conveying structure;

[0076] The connecting track is located at one end of the first conveying track, and the connecting platform is located at the other end of the first conveying track;

[0077] At one end of the first conveying track, the carrier is conveyed from the first conveying track to the second conveying track by a first material conveying device and via the connecting track;

[0078] At the other end of the first conveying track, the carrier is transported from the second conveying track to the first conveying track through the second material transporting device and the connecting platform.

[0079] In this embodiment, the limiting structure is a plurality of limiting blocks installed on the chain, and the carrier can be located between two adjacent limiting blocks, and the position of the carrier relative to the chain is limited by the limiting blocks.

[0080] like Figure 16 to Figure 17As shown, the limiting mechanism 502 includes a support frame 5021, a support seat 5022, a limiting driving cylinder 5023, a limiting assembly 5024 and a fixing block 5025. The support frame is installed on a workbench, the support seat is connected to the support frame via a linear guide rail, and the support seat is fixed to a belt via a connecting block. The limiting driving cylinder is installed on the mounting seat, and the limiting assembly is driven to translate up and down by the limiting driving cylinder, so as to realize whether the carrier is limited or not by the limiting assembly.

[0081] In this embodiment, the carrier is provided with a limiting hole, and the limiting component is a limiting column head matching the limiting hole. The limiting column head is inserted into the limiting hole to limit the carrier, so that the carrier is transported with the belt.

[0082] like Figures 8 to 10 As shown, the first material handling device 30 includes a mounting frame 301, a toggle seat 303, and a Y-direction driving unit 304 capable of driving the toggle seat to translate in the Y direction. The mounting frame is mounted at the end of the first conveying track, the toggle seat is mounted on the mounting frame, and the toggle seat translates in the Y direction along the mounting frame.

[0083] One side of the shifting seat is aligned with the carrier, and the shifting seat is driven to translate along the Y direction by the Y-direction driving unit to drive the carrier to translate, and the carrier is transported to the second conveying track through the connecting track. In this embodiment, the Y-direction driving unit is a cylinder, but is not limited thereto.

[0084] In this embodiment, the structure of the second material handling device is similar to that of the first material handling device, so it is not described in detail. Of course, different structures can also be used as long as the carrier can be transported from the second conveying track to the first conveying track.

[0085] In this embodiment, through this first material handling device, an automated operation mode is adopted to realize the transportation of materials (such as carriers) between two parallel conveying tracks, which is convenient for realizing a U-shaped conveying trajectory of materials. First, it can adapt to the space requirements of mechanical equipment; second, it saves a lot of manpower.

[0086] like Figures 8 to 10 As shown, the mounting frame is provided with a leveling structure 305 located directly above the connecting track for leveling the workpiece placed on the carrier;

[0087] The leveling structure includes a rotatable roller 3051, and the roller is located directly above the connecting track.

[0088] Advantages of the leveling mechanism: For example, the distance between the roller and the upper surface of the connecting track is pre-set. If the bearing is not completely aligned with the bearing hole during material discharge, one side of the bearing will be lifted up. When the carrier passes through the roller, the roller will push the slightly misaligned bearing into the bearing hole, which can correct the problem of inaccurate manual material discharge position to a certain extent and avoid the subsequent scrapping of materials due to inaccurate material placement and press-fitting.

[0089] like Figures 8 to 10 As shown, on both sides of the connecting track, each side is provided with a rotatable shaft sleeve 3021 for assisting the translation of the carrier.

[0090] The workpiece is a flange plate 200 and a bearing (not shown in the figure), and the bearing is placed in the bearing hole 2001 of the flange plate. The distance between the roller and the upper surface of the connecting track is preset. If the bearing is not completely aligned with the bearing hole during material discharge, one side of the bearing will be tilted. When the carrier passes through the roller, the roller will push the slightly misaligned bearing into the bearing hole.

[0091] like Figures 8 to 10 As shown, a first stopper 3011 for limiting the moving stroke of the Y-axis driving unit is provided on one side of the mounting frame close to the first conveying track.

[0093] like Figures 8 to 10 As shown, the vertical plate is provided with a second limit member 30321 for limiting the movement stroke of the Y-axis driving unit.

[0094] like Figure 11 to Figure 15 As shown, a positioning device 40 for positioning the carrier is provided at the second conveying track and the connecting platform, a first positioning mechanism 401 is provided on one side of the second conveying track and in the Y direction, a second positioning assembly 402 is provided on one side of the second conveying track and along the Y direction, the first positioning mechanism includes a first positioning assembly 4011 and a first Z-direction driving unit 4012 capable of driving the first positioning assembly to translate up and down, the first positioning assembly is located above the second conveying track, the carrier is clamped by the first positioning assembly and the second positioning assembly, and the movement of the carrier in the X direction is limited;

[0095] A second positioning mechanism 403 is provided on one side of the second conveying track and along the X direction. The second positioning mechanism includes a third positioning component 4031 and a flip driving cylinder (not shown) capable of driving the third positioning component to flip. The flip driving cylinder is installed on the connecting platform. The flip driving cylinder drives the third positioning component to press the carrier from above to limit the movement of the carrier in the Z direction and the Y direction.

[0097] like Figure 11 to Figure 15 As shown, the first positioning assembly and the second positioning assembly both include a limiting column mounting seat 4021 and a plurality of limiting columns 4022, and the limiting columns are mounted on the limiting column mounting seat, and the carrier is clamped from the X direction through the circumferential surface of the limiting column of the first positioning assembly and the circumferential surface of the limiting column of the second positioning assembly.

[0098] In this embodiment, the carrier is positioned and limited from multiple directions through the first positioning mechanism, the second positioning assembly and the third positioning mechanism, and then through the cooperation of other mechanisms, it is convenient to automatically separate the carrier on the conveyor path and the workpiece placed on the carrier, and the carrier will not be lifted up when the workpiece is grabbed, which facilitates the return of the carrier and the subsequent processing of the workpiece and saves a lot of manpower.

[0099] like Figure 11 to Figure 15 As shown, the first Z-direction driving unit includes a first Z-direction driving cylinder 40121, a guide column 40122 and a guide sleeve 40123, the driving rod of the first Z-direction driving cylinder is connected to the lower end of the guide column, the guide column is installed on the guide sleeve, the first positioning assembly is installed on the upper end of the guide sleeve, the relative position of the guide sleeve in the Z direction remains unchanged, and the guide column is driven to move up and down relative to the guide sleeve by the first Z-direction driving cylinder, thereby driving the first positioning assembly to move up and down.

[0100] like Figure 11 to Figure 15 As shown, the third positioning assembly includes a positioning wheel 40311 and a positioning wheel mounting seat 40312, the positioning wheel is mounted on the positioning wheel mounting seat, and the lower surface of the positioning wheel and the portion 403111 extending out of the positioning wheel mounting seat forms an upper limit position for the carrier;

[0101] The third positioning assembly also includes a connecting block 40313 and a rotating shaft 40314. The connecting platform is provided with two parallel strip grooves 40321. The connecting platform is equipped with a connecting frame 40322. The connecting frame passes through the strip grooves, and the upper surface is flush with the connecting platform. The output end 40331 of the flip driving cylinder is rotatably connected to the lower end of the connecting block. The rotating shaft passes through the lower end of the positioning wheel mounting seat, the connecting frame and the connecting block in sequence.

[0102] When the driving end of the flip driving cylinder is retracted, the connecting block is driven to move, and through the transmission between the rotating shaft and the positioning wheel mounting seat, the two sides of the positioning wheel mounting seat can be perpendicular to the connecting platform to limit the carrier;

[0103] When the driving end of the flip driving cylinder extends out, the connecting block is driven to move, and through the transmission between the rotating shaft and the positioning wheel mounting seat, the two sides of the positioning wheel mounting seat can be stuck in the strip groove and the circumferential surface of the positioning wheel faces upward. In this embodiment, the flip driving cylinder is installed on the connecting frame. In this embodiment, the connecting block is fixed to the rotating shaft, the positioning block mounting seat is relatively fixed to the rotating shaft, and the connecting frame and the rotating shaft are rotatably connected through a bearing.

A first positioning mechanism 401 is also provided on the right side of the first conveying track, which is used to temporarily limit the position of the carrier when it is transported to the first conveying track by the second material handling device to avoid position deviation and affect the subsequent circulation process.

[0106] like Figure 5 As shown, the gripping mechanism 70 includes a clamp 701, a clamp driving cylinder 702 capable of driving the two parts of the clamp to move closer or farther away, a clamp lifting cylinder 703 capable of driving the clamp to move up and down, and an X-direction driving unit (not shown) capable of driving the clamp to translate in the X direction. The X-direction driving unit can be driven by a cylinder or by a motor screw, which is a prior art and will not be described in detail.

[0107] like Figure 18 to Figure 22 As shown, the material dividing device further includes a pushing mechanism 604, one end of the good product conveying track is connected to the feed port 6031 of the bad product conveying bin, the pushing mechanism is arranged on the good product conveying track, and the pushing mechanism includes a pushing plate 6041 and a pushing cylinder 6042 capable of pushing the pushing plate to move;

[0108] The workpiece to be grasped is grasped by the material taking mechanism (not shown in the figure), and the workpiece is conveyed to the top of the good product conveying track by the material taking driving unit;

[0109] The side where the defective product conveying bin is located is defined as the left side. When the workpiece is a good product, the push plate is located at the left end of the good product conveying track, and the workpiece is located on the right side of the push plate. The push plate is driven rightward by the push cylinder to pull the good product to move rightward along the good product conveying track.

[0110] When the workpiece is a defective product, the workpiece is located on the left side of the push plate, and the push plate is driven leftward by the push cylinder to push the defective product into the defective product conveying bin.

[0111] like Figure 18 to Figure 22 As shown, the material picking mechanism includes a material picking support claw 6011, a support claw driving cylinder 6012 capable of driving the material picking support claw to open or close, and a material picking drive cylinder 6013 capable of driving the material picking support claw to rise and fall. The support claw driving cylinder drives the support claw to open and clamp the through hole of the flange plate to fix the flange plate. (In this embodiment, the workpiece is a flange plate with a bearing pressed on it, and the through hole is the through hole of the bearing. However, it is not limited to this, and other workpieces with similar structures can also adopt this structure.)

[0112] The defective product conveying bin is a bin that is inclined obliquely downward from the feed end.

[0113] like Figure 18 to Figure 22 As shown, the bottom of the defective product conveying bin is provided with multiple rows of rollers (6032) for facilitating the sliding of defective products.

[0114] like Figure 18 to Figure 22 As shown, the material picking drive unit is a motor screw transmission mechanism (not shown in the figure), and the material picking mechanism is driven to translate along the Y direction by the motor screw transmission mechanism.

[0115] like Figure 18 to Figure 22 As shown, the pushing mechanism also includes a fixed sleeve 6043 and a sliding rod 6044, the fixed sleeve is arranged on the sliding rod, the fixed sleeve is installed on the good product conveying track, one end of the sliding rod is connected to the pushing plate, and the sliding rod can slide along the sliding sleeve.

[0116] The pusher mechanism is provided with two groups, which are respectively located on both sides of the good product conveying track. (Two groups have a more reasonable structure and are more stable when pushing the workpiece. Of course, one group can also realize the basic pusher function.)

[0117] In this embodiment, the material dividing device can realize the separate discharge of good and defective workpieces (such as flange plates) through the design of mechanisms such as the material picking mechanism, the good product conveying track, the defective product conveying bin and the pushing mechanism, which is convenient for subsequent rework and re-inspection, and improves the degree of automation of the flange plate bearing automatic pressing equipment; it also saves a lot of manpower and has the characteristics of simple structure, high speed and stable quality.

[0118] like Figure 1 As shown, in this embodiment, the press-in detection device further includes a cover body 500, which covers the outer periphery of the workbench, and the left end of the first conveying track is a loading area 5003. A mounting protection plate 5001 is provided on one side of the cover body and located in the loading area, and the mounting protection plate isolates the operator from the operating area of ​​the equipment. This design completely isolates the operator from the motion mechanism.

[0119] like Figure 1 As shown, the cover body is provided with a mounting grating 5002 located at the mounting protection plate for detecting whether the operator has left the working area, and the two safety gratings are electrically connected to the control system of the press-in detection device. If the human body part has not left the working area, the device cannot be started, thereby improving the safety of the device.

[0120] The press-in detection device is provided with two start buttons (not shown in the figure) which must be pressed by both hands simultaneously to start the press-in detection device. The two start buttons (not shown in the figure) are electrically connected to the control system of the press-in detection device.

[0121] When in action, the operator is required to press two start buttons at the same time to press the detection equipment to work, which further ensures that the operator is completely outside the equipment when the equipment starts working. Compared with the existing design of one start button, it is helpful to avoid the situation where the equipment starts running due to accidental touching of the start button, which can improve the personal safety of the operator and reduce the occurrence of safety accidents.

[0122] The working principle and working process of the present invention are as follows:

[0123] The flange plate and the bearing are placed on the carrier manually, and the flange plate and the bearing plate to be pressed are transported to the press through the conveyor line, and the two are pressed. Then the grabbing mechanism grabs the flange plate and takes it to the lettering inspection line for subsequent processes. At the same time, the conveyor line takes the carrier back to the original position to prepare for the next action process. In the lettering inspection line, the third conveyor track drives the carrier to flow, and lettering and appearance inspection are carried out in turn. Finally, the carrier is sent to the material separation device to separate and unload according to good and bad products.

[0124] The specific working process of the flow conveyor line is as follows:

[0125] The empty carrier is conveyed to the end (defined as the left end) of the first conveying track through the first conveying track (driven by the belt transmission structure). At this time, one side of the triangular plate of the toggle plate seat is just aligned with the side of the carrier, and the flange plate and the bearing to be pressed into the bearing are placed in the carrier. Then the Y-axis driving unit drives the toggle seat to translate along the Y direction, driving the carrier to translate, and through the auxiliary effect of the connecting track and the sleeve installed on the connecting track, the carrier is transported to the second conveying track for subsequent processes. Then the Y-axis driving unit drives the toggle seat back and repeats the above actions; in the above process, when the carrier passes through the leveling mechanism, the distance between the roller and the upper surface of the connecting track is pre-set. If the bearing is not fully aligned with the bearing hole during material discharge, one side of the bearing will be tilted. When the carrier passes through the roller, the roller will push the slightly misaligned bearing into the bearing hole, correcting the problem of inaccurate position of manual material discharge to a certain extent, and avoiding the subsequent scrapping of materials due to inaccurate material placement and pressing.

[0126] The subsequent process here means that the carrier is just inserted between the limit blocks provided on the chain, and then moved to the processing station (such as the press-fitting station, the bearing is pressed into the flange plate by the press-fitting machine) under the drive of the sprocket chain transmission structure, and then the carrier is transported to the right end of the second conveying track, that is, the positioning device. After the sensor detects that the carrier is in place, the push rod of the first Z-direction driving cylinder is retracted, and the guide column is driven to move upward relative to the guide sleeve, thereby driving the limit column of the first positioning assembly to extend upward to the side of the carrier, and the carrier is clamped by the cooperation of the limit columns of the first positioning assembly and the second positioning assembly to limit the movement of the carrier in the X direction;

[0127] At the same time, the driving end of the flip driving cylinder retracts, driving the connecting block to move, and through the transmission between the rotating shaft and the positioning wheel mounting seat, the two sides of the positioning wheel mounting seat can be perpendicular to the connecting platform, that is, the lower surface of the positioning wheel and the part extending out of the positioning wheel mounting seat press the carrier from above, forming an upper limit position for the carrier, limiting the movement of the carrier in the Z direction and the Y direction and playing a limiting role on the carrier;

[0128] Through the above-mentioned action process, the carrier is positioned to prevent the carrier from moving. At this time, the flange plate after the bearing is pressed is taken away in cooperation with other mechanisms. Without the positioning device, the function of taking away the flange plate alone cannot be realized. The flange plate taken away alone can be used for subsequent testing, laser engraving, etc.

[0129] Afterwards, the driving end of the flip driving cylinder extends out to drive the connecting block to move, and through the transmission between the rotating shaft and the positioning wheel mounting seat, the two sides of the positioning wheel mounting seat can be stuck in the strip grooves and the circumferential surface of the positioning wheel faces upward to avoid interference when the carrier passes through the connecting platform. In conjunction with the second material handling device, the carrier can be transported to the connecting platform, and the carrier is transported to the right end of the first conveying track by the second material handling device. The first positioning component of the first positioning mechanism descends (the principle is the same as that of the positioning device), and then the limiting driving cylinder of the limiting mechanism drives the limiting column head of the limiting component to extend into the limiting hole of the carrier to position the carrier, and then the carrier is transported to the left end of the first conveying track by the belt transmission component, and the next process is repeated;

[0130] The working process of the material dividing device is as follows:

[0131] The side where the defective product conveying bin is located is defined as the left. This embodiment is described by taking the flange plate and bearings placed on the carrier as an example. After the material picking support claw is driven by the material picking drive cylinder to descend into place, the material picking support claw extends into the through hole of the bearing of the flange plate, and then the support claw driving cylinder drives the material picking support claw to open to grab the flange plate with the bearing installed, and the flange plate is conveyed to the top of the good product conveying track through the material picking drive unit. When the flange plate is a good product, the push plate is located at the left end of the good product conveying track, and the flange plate is located on the right side of the push plate. The push plate is driven to the right by the push cylinder to pull the good product along the good product conveying track, and the good product enters the good product conveying track; when the flange plate is a defective product, the flange plate is located on the left side of the push plate, and the push plate is driven to the left by the push cylinder to push the defective product into the defective product conveying bin.

[0132] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
