[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0041] refer to Figure 1-Figure 7 The present embodiment provides an automatic piston 9 sorting machine, including a control system, a feeding device 2, a detection device 3 and a sorting device 4, and is provided with a material taking device 1 for transporting the piston 9 between the various devices.

[0042] The material picking device 1 includes a first grabbing hand 11, a second grabbing hand 12 and a driving module for providing driving. The first grabbing hand 11 is used to go back and forth between the feeding device 2 and the detection device 3, and is used to obtain the piston 9 to be detected on the feeding device 2 and transport it to the detection device 3 for dimensional accuracy detection. The second grabbing hand 12 is used to go back and forth between the detection device 3 and the sorting device 4, and is used to obtain the piston 9 that has been detected on the detection device 3 and transport it to the sorting device 4 for storage.

[0043] like Figure 7 In this embodiment, the driving module includes a sliding frame 13 arranged opposite to each other on both sides, a sliding track 14 is arranged on the sliding frame 13, and two groups of linear tracks 15 are arranged across the sliding tracks 14 on both sides, and the linear tracks 15 are slidably installed on the sliding tracks 14, and the two groups of linear tracks 15 are driven by two groups of motors respectively. A lifting cylinder is arranged on each group of linear tracks 15, and a claw clamp is arranged at the driving end of the lifting cylinder, and the claw clamp is the first grabbing hand 11 or the second grabbing hand 12 for grabbing the piston 9. Through the cooperation of the sliding track 14, the linear track 15, and the lifting cylinder, the first grabbing hand 11 and the second grabbing hand 12 can move in three directions of X-axis, Y-axis, and Z-axis, so as to realize the grabbing and transportation of the piston 9.

[0044] In order to better grasp the piston 9 , V-shaped or arc-shaped clamping parts are provided at the claw clamping ends of the first grasping hand 11 and the second grasping hand 12 , so as to better grasp the piston 9 .

[0045] The feeding device 2 includes a feeding conveyor belt 21, a feeding conveyor belt 22 and a lifting platform 23. The feeding conveyor belt 21 and the feeding conveyor belt 22 are arranged in upper and lower layers, and the lifting platform 23 has an up-and-down lifting function, and the feeding conveyor belt 21 and the feeding conveyor belt 22 are connected by lifting. Figure 2 The lifting platform 23 is composed of a lifting frame and a lifting motor arranged in the lifting frame. The lifting platform 23 is slidably installed in the lifting frame and driven by the lifting motor to move up and down. The loading conveyor belt 21 is horizontally arranged and is a power conveyor belt, which can convey the storage frame 8 with the piston 9 to be tested to the lifting platform 23. The unloading conveyor belt 22 is inclined and tilted upward toward the lifting platform 23. The unloading conveyor belt 22 is a non-powered conveyor belt, which uses the inclination to provide power to transport the empty storage frame 8 on the lifting platform 23 where the piston 9 has been removed out of the lifting platform 23.

[0046] In order to better carry out the loading and transportation of the full material storage frame 8 and the unloading and transportation of the empty material storage frame 8, the loading conveyor belt 21, the unloading conveyor belt 22 and the lifting platform 23 all include a plurality of rollers to provide rolling force.

[0047] The material storage frame 8 on which the piston 9 to be tested is placed is picked up by the first grabber 11 on the lifting platform 23. In order to smoothly obtain the piston 9 by the first grabber 11, an identifier 24 and a clamping and positioning device are provided at the upper end of the lifting frame. The identifier 24 is provided on the side facing the feeding conveyor belt 21, and is used to identify whether the material storage frame 8 has reached the specified position. The clamping and positioning device is used to clamp the material storage frame 8 and stabilize it on the lifting platform 23 after the identifier 24 identifies that the material storage frame 8 has reached the lifting platform 23.

[0048] like Figure 3 , the clamping and positioning device is arranged on a side close to the feeding conveyor belt 21, and the clamping and positioning device is correspondingly pushed at a corner of the material storage frame 8. The clamping and positioning device includes a clamping block 25 and a positioning cylinder 26 driving the clamping block 25. The lifting platform 23 is provided with a material frame rib 27 in conjunction with the clamping and positioning device, and the material frame rib 27 forms a right-angle rib structure. The specific clamping is that when the material storage frame 8 moves to the lifting platform 23, the identifier 24 recognizes that the material storage frame 8 is in place, and the positioning cylinder 26 drives the clamping block 25 to abut against a corner edge of the material storage frame 8, and continues to push until the material storage frame 8 abuts against the material frame rib 27, and stabilizes the material storage frame 8 under the pushing of the clamping block 25 and the limiting of the material frame rib 27, and releases the clamping and positioning when the lifting platform 23 descends.

[0049] At the same time, in order to avoid large-scale loading and testing of the piston 9, in this embodiment, the loading device 2 also includes a piston reflux device 5. When the detection device 3 is temporarily unable to detect the piston 9 or the piston 9 at the sorting device 4 is full and cannot be stored temporarily, the piston 9 is recovered by the piston reflux device 5 to ensure the stability of the device's automated process.

[0050] The piston reflux device 5 comprises a reflux conveyor belt 51, a reflux channel 52 and a reflux push block 53. The reflux conveyor belt 51 is arranged on one side of the feeding conveyor belt 21, and the reflux conveyor belt 51 is connected to the reflux channel 52. The reflux push block 53 is arranged on one side of the reflux channel 52, and the reflux pusher is arranged toward the reflux conveyor belt 51. The reflux push block 53 is driven by a reflux cylinder 54 to push the piston 9 on the reflux channel 52 to the reflux conveyor belt 51. When the piston 9 needs to reflux, the first gripper 11 places the obtained piston 9 on the reflux channel 52, and pushes it into the reflux conveyor belt 51 through the reflux push block 53 for recycling. The recycled piston 9 can be reinstalled in the storage frame 8 for loading. The piston 9 obtained by the first gripper 11 can be a piston 9 that has been obtained in the storage frame 8 and cannot be placed for detection, or a piston 9 that has been detected at the detection device 3 but cannot be sorted.

[0051] The detection device 3 includes a detection platform 31, an ejection mechanism 32 and a push-back mechanism 33. The detection platform 31 includes a piston inlet 311 and a piston 9 channel arranged through it; the ejection mechanism 32 and the push-back mechanism 33 are relatively arranged on both sides of the piston 9 channel, and the ejection mechanism 32 is arranged on the side corresponding to the piston inlet 311.

[0052] like Figure 5 The push-out mechanism 32 and the push-back mechanism 33 both include a push block 34 and a push cylinder 35. The piston inlet 311 is a V-shaped opening, which is convenient for the piston 9 to be pushed into the piston 9 channel and placed at the detection position for dimensional accuracy detection. The piston inlet 311 is used for the first gripper 11 to obtain or place the piston 9, and for the second gripper 12 to obtain the piston 9. The push-out mechanism 32 is used to push the piston 9 from the piston inlet 311 into the piston 9 channel to send the piston 9 for inspection. The push-back mechanism 33 is used to push the piston 9 from the piston 9 channel back to the piston inlet 311 to send out the inspected piston 9. A detection mechanism is built into the detection table 31, and the detection mechanism can use an existing pneumatic measuring instrument or pneumatic probe to measure the piston 9.

[0053] In order to be suitable for the sorting of different batches of pistons 9, a width clamp and a height limiter are set on the inspection table 31. The width clamp includes a left clamp block 312, a right clamp block 313 and a width adjustment member, and the width adjustment member is used to adjust the width between the left clamp block 312 and the right clamp block 313; the left clamp block 312 and the right clamp block 313 are assembled to form the piston 9 channel. The height limiter includes a left pressure block 314 and a right pressure block 315; the left pressure block 314 and the right pressure block 315 are arranged opposite to each other and spaced apart, and the height between the left pressure block 314 and the right pressure block 315 and the piston 9 channel is adjustable.

[0054] At the same time, it is convenient to adjust and calibrate the width clamp and the height limiter. The detection device 3 also includes a positioning base 36, which is used to place the piston 9 standard parts. The same batch of randomly selected piston 9 standard parts are used to adjust the width and height of the piston 9 channel of the detection platform 31. When there are large size differences in the pistons 9 in the batch, they will be stuck at the piston 9 channel and cannot be pushed. Feedback can be given to the control system to handle the defective piston 9. An anti-vibration sensing device can be optionally set at the output end of the push cylinder 35. When the piston 9 is stuck and the push cylinder 35 cannot be pushed, vibration will be generated, which can trigger the anti-vibration sensing device to identify that it cannot be pushed.

[0055] In order to facilitate the processing of defective pistons 9 , a defective piston conveyor belt 6 is provided between the detection device 3 and the sorting device 4 , and the defective piston conveyor belt 6 is used to place the defective pistons 9 obtained by the second gripper 12 and to recover the defective pistons 9 .

[0056] The sorting device 4 includes a material storage rack 41 and a sorting material tray 42 placed on the material storage rack 41; when the second grabber 12 places the piston 9 obtained from the detection table 31 on the sorting material tray 42, it simultaneously feeds back to the control system to record the position information of the piston 9 on the sorting material tray 42. At the same time, a sorting grabbing device 7 is arranged above the sorting device 4, and the sorting grabbing device 7 is driven by the control system to select and grab the piston 9.

[0057] In the sorting device 4, the size accuracy of the piston 9 is sorted by setting the array distribution of the piston 9 placement position of the sorting material tray 42 to mark the position of the piston 9, and the sorting material tray 42 is divided into the X-axis and the Y-axis. If the first piston detection size is A, and the second piston detection size is B, when the second grabber 12 grabs, the first piston size A and the second piston size B are recorded in the system. Correspondingly, when the second grabber 12 places the piston 9, the first piston is placed at (X1, Y1) and the second piston is placed at (X2, Y2). At this time, the control system records the piston 9A size position (X1, Y1) and the piston 9B size position (X2, Y2). When the sorting material tray 42 is transported to the selection, an A-size piston 9 is required, which drives the sorting grabbing device 7 to grab the piston 9 at the sorting material tray 42 (X1, Y1), so that the required piston 9 can be quickly selected and grabbed.

[0058] In order to increase the storage of the piston 9 and to connect the detection, sorting and matching, the storage rack 41 in this embodiment is provided with three layers of slideways 43, and one layer of the slideway 43 is slidably mounted with a sorting material tray 42. Figure 6 Each layer of slide 43 is an independent slide 43, and a linear sliding module 44 is arranged on one side of the slide 43. The linear sliding module 44 is connected to the sorting tray 42 through a connecting plate, and is used to drive the sorting tray 42 to slide on the slide 43. The sorting tray 42 slides on the slide 43 and has a first position and a second position; the first position is close to the detection device 3, and when the sorting tray 42 is at the second position, the sorting grabbing device 7 is arranged above the sorting tray 42.

[0059] In order to stabilize the slideway 43 of the sorting material tray 42, a limiting device 45 is provided at both ends of the slideway 43, and a buffer 46 is provided at both ends of the linear sliding module 44. The buffer 46 is used to buffer the sliding impact of the linear slideway 43 module on the sorting material tray 42. The limiting device 45 is used to limit the sliding position of the sorting material tray 42, so that the sorting material tray 42 can stop at the first position or the second position.

[0060] The sorting tray 42 receives the piston 9 detected by the detection device 3 at the first position and performs size sorting and marking. The sorting tray 42 selects the material to be taken at the second position. The three sorting trays 42 arranged on the three-layer slide 43 place or obtain the piston 9 from top to bottom.

[0061] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
