[0047] The piston is one of the basic parts of the engine and is the heart of the engine. At present, automobile pistons are developing towards high strength, high wear resistance, high precision, low expansion, lightweight, and structural combination. In the processing and production of pistons, after the pistons are processed and tested, in order to facilitate their transportation and storage, the pistons need to be arranged and placed in a placement frame, and then the placement frames with the pistons are stacked and placed together. In the prior art, the framing of pistons and the stacking of placement frames are generally done manually, which not only has low work efficiency, but is also time-consuming and labor-intensive, and has high labor intensity.

[0048] The present invention provides a frame loading and palletizing device 100 .

[0049] See also Figure 1-Figure 10 In one embodiment of the present invention, the frame loading and stacking device 100 is used to place the piston in the placement frame 200 and stack the placement frame 200 with the piston placed therein. The frame loading and stacking device 100 includes a feeding device 1, a conveying device 2, a detection device 3, a transporting device 4 and a stacking device 5. The feeding device 1 includes a bearing mechanism 11 and a clamping mechanism 12. The bearing mechanism 11 is used to stack the placement frames 200; the conveying device 2 includes a bracket 21 and a transmission belt 22 installed on the bracket 21 and extending along a first horizontal direction. The top of the transmission belt 22 has a feeding station 221, a discharging station 222 and a discharging station 223 in sequence along the first horizontal direction. The feeding device 1 is arranged near the feeding station 221, and a first positioning mechanism 23 is arranged at a position near the discharging station 222 on the bracket 21; the clamping mechanism 12 is used to clamp the placement frame 200 on the bearing mechanism 11 and place it on the transmission belt 22 at the feeding station 221. The transmission belt 22 can drive the placement frame 200 to move to the discharge station 222 in sequence along the first horizontal direction, and the first positioning mechanism 23 is used to position the placement frame 200 at the discharge station 222; the detection device 3 is arranged on one side of the bracket 21 along the first horizontal direction, and the detection device 3 is used to detect the piston; the material transport device 4 is arranged close to the detection device 3, and the material transport device 4 includes a mechanical arm 41, and the mechanical arm 41 is used to transfer the detected piston to the placement frame 200 located at the discharge station 222; the transmission belt 22 can also drive the placement frame 200 with the piston placed thereon to move to the discharge station 223; the stacking device 5 is arranged close to the discharge station 223, and the stacking device 5 includes a material receiving mechanism 52, a stacking mechanism 51 and an auxiliary positioning mechanism 53, the stacking mechanism 51 stacks the placement frame 200 located at the discharge station 223 on the material receiving mechanism 52, and the auxiliary positioning mechanism 53 is used to position the placement frame 200 located on the material receiving mechanism 52.

[0050] The frame loading and stacking device 100 in this embodiment is convenient for the clamping and placing mechanism 12 to sequentially clamp each placement frame 200 and sequentially place them on the conveying device 2 by stacking multiple placement frames 200 on the carrying mechanism 11. Specifically, the conveying mechanism has a feeding station 221, a discharging station 222 and a discharging station 223 on the conveying belt 22. The clamping and placing mechanism 12 places the placement frame 200 on the conveying belt 22 at the feeding station 221. Driven by the conveying belt 22, the placement frame 200 moves toward The material discharging station 222 moves. When the material discharging station 222 is reached, the first positioning mechanism 23 positions the placement frame 200 at the material discharging station 222, thereby keeping the placement frame 200 fixed. The first positioning mechanism 23 can also properly adjust and correct the placement posture of the placement frame 200, so that the robot arm 41 can place the piston in the placement frame 200. After the detection mechanism detects the piston, the piston is transferred to the placement frame 200 located at the material discharging station 222 under the action of the robot arm 41, thereby completing The process of placing the piston in the placement frame 200 is completed. When a certain number of pistons are placed in the placement frame 200, the first positioning mechanism 23 no longer positions the placement frame 200. At this time, the placement frame 200 can continue to move to the discharge station 223 along with the transmission belt 22. When the placement frame 200 is located at the discharge station 223, the stacking mechanism 51 in the stacking device 5 clamps the placement frame 200 and stacks it on the receiving mechanism 52, and the auxiliary positioning mechanism 53 is used to position the placement frame 200 located on the receiving mechanism 52, thereby preventing the multiple placement frames 200 stacked on the receiving mechanism 52 from shaking during the stacking of the placement frames 200; through the above-mentioned feeding device 1, conveying device 2, detection device 3, material transport device 4 and stacking device 5, the piston can be automatically loaded into the placement frame 200 after detection, and the placement frame 200 with the piston can be stacked without relying on manual operation, which can significantly improve the work efficiency of piston framing and stacking and reduce manual labor intensity.

[0051] Specifically, it should be noted that the carrying mechanism 11 is used to stack the placement frames 200 without pistons, and the clamping mechanism 12 is on the clamping placement frames 200, and each time the top placement frame 200 on the carrying mechanism 11 is clamped. Stacking means stacking, and the auxiliary positioning mechanism 53 is mainly used to position the top placement frame 200 on the receiving mechanism 52, so as to prevent all the placement frames 200 on the receiving mechanism 52 from shaking.

[0052] It should be noted that the placement frame 200 mentioned in the present embodiment is a square placement frame 200 having four corners. Specifically, a plurality of latches are fixed to the top of each placement frame 200, and a slot for inserting the latches is provided at the bottom of each placement frame 200. When the placement frames 200 are stacked, the latches on the lower placement frame 200 are inserted into the slots of the upper placement frame 200, thereby improving the stability of the placement frames 200 when stacked.

[0053] Furthermore, a plurality of mold bases for inserting pistons in a mating connection manner are installed on the inner bottom wall of the placement frame 200. The piston is placed in the placement frame 200, and the piston is sleeved on the mold base in a mating connection manner to prevent the piston from shaking when the placement frame 200 is moved.

[0054] It should be noted that the mechanical arm 41 and the detection device 3 may be the mechanical arm 41 and the piston detection device 3 in the prior art.

[0055] like Figure 1 As shown, in this embodiment, the first horizontal direction is the front-to-back direction, the second horizontal direction is the left-to-right direction, and the vertical direction is the up-down direction.

[0056] See also Figure 2 and Figure 3 In one embodiment, the clamping mechanism 12 includes a base 121, a lifting seat 122 and a lifting plate 123; the base 121 extends along a second horizontal direction, the second horizontal direction is perpendicular to the first horizontal direction, the conveying device 2 and the supporting mechanism 11 are both arranged on one side of the base 121 along the first horizontal direction, and the supporting mechanism 11 and the conveying device 2 are spaced apart along the second horizontal direction, the lifting seat 122 is slidably arranged on the base 121, and the lifting seat 122 can slide along the second horizontal direction; one side of the lifting plate 123 slides with the lifting seat 122 toward one side of the conveying device 2, and the lifting plate 123 can be lifted and lowered vertically relative to the lifting seat 122, and a clamp 124 is provided at the bottom of the lifting plate 123, and the clamp 124 is used to clamp the placement frame 200 on the supporting mechanism 11 and place it on the transmission belt 22 at the feeding station 221.

[0057] It can be understood that the precise positioning of the placement frame 200 can be achieved through the combination of the base 121, the lifting seat 122 and the lifting plate 123. The sliding of the lifting seat 122 along the second horizontal direction and the lifting and lowering action of the lifting plate 123 along the vertical direction ensure that the clamping claw 124 can reach the top of the carrying mechanism 11 and accurately clamp the placement frame 200 from the carrying mechanism 11, and continue to move to the feeding station 221 to accurately place the placement frame 200 on the transmission belt 22. When the clamping mechanism 12 is working, the lifting seat 122 is first moved so that the lifting plate 123 is located above the carrying mechanism 11. The lifting plate 123 is moved to the top of the mechanism 11, and then after the lifting plate 123 is lifted vertically to reach a suitable position, the topmost placement frame 200 is directly grasped by the clamp 124, and then the height of the lifting plate 123 is adjusted to be higher than the conveyor belt, and then the lifting seat 122 is moved to move the lifting plate 123 to the position above the transmission belt 22 corresponding to the feeding station 221, and the clamp 124 releases the placement frame 200 so that the placement frame 200 falls on the transmission belt 22; the automated placement process of the placement frame 200 reduces manual operation, reduces labor intensity, and improves work efficiency.

[0058] Specifically, the lifting plate 123 is slidably connected to the lifting seat 122 via a slide rail.

[0059] Specifically, two clamping jaws 124 are spaced apart at the bottom of the lifting plate 123 . Both of the two clamping jaws 124 are pneumatic clamping jaws 124 . Both of the two clamping jaws 124 are used to clamp the frame of the placement frame 200 .

[0060] In one embodiment, the carrying mechanism 11 includes a carrying vehicle 111 and a fixed frame 112. The fixed frame 112 encloses a limited space with an entrance. The entrance is located on the side of the fixed frame 112 away from the conveying device 2. The carrying vehicle 111 has a carrying plate for carrying the placement frame 200. The carrying vehicle 111 can enter and exit the limited space from the entrance.

[0061] It can be understood that by supporting the stacked placement frames 200 on the supporting plate of the carrier 111, the placement frames 200 can be quickly moved to the position of the fixed frame 112. When all the placement frames 200 on the carrier 111 are clamped, the carrier 111 can be quickly moved out and replaced with another carrier 111 carrying the placement frames 200. Multiple carriers 111 can be used alternately, thereby improving the supply efficiency of the placement frames 200; and through the fixed frame 112, the carrier 111 can be limited in the limited space, thereby ensuring that the placement frames 200 are stably stacked and placed, which is convenient for the clamp 124 to grasp.

[0062] Specifically, the fixing frame 112 is fixedly installed on the ground, and the fixing frame 112 cooperates with the side of the carrying plate to fix the carrying vehicle 111 .

[0063] like Figure 4-Figure 7 As shown, in one embodiment, the conveying device 2 includes a bracket 21 and a transmission belt 22, the bracket 21 extends along a first horizontal direction, and a rotating shaft 25 is provided at both ends of the bracket 21 along the first horizontal direction, and the rotating shaft 25 extends along a second horizontal direction. The bracket 21 is also provided with a first rotating driving member 26 that is transmission-connected to one of the rotating shafts 25; the transmission belt 22 is installed on the bracket 21, and the transmission belt 22 is transmission-connected to the two rotating shafts 25; the top of the transmission belt 22 is sequentially provided with a feeding station 221, a discharging station 222 and a discharging station 223 along the first horizontal direction; the placement frame 200 is placed on the transmission belt 22 at the feeding station 221, and the first rotating driving member 26 can drive the corresponding rotating shaft 25 to rotate, so as to drive the transmission belt 22 to transport the placement frame 200 to move to the discharging station 222 and the discharging station 223 in sequence.

[0064] It can be understood that by setting the transmission belt 22 on the bracket 21, the stability of the transmission belt 22 can be ensured, and the placement frame 200 can be kept stable during transportation; by driving the rotating shaft 25 through the first rotating drive member 26, and then driving the transmission belt 22 to operate, the placement frame 200 can be automatically transferred from the feeding station 221 to the discharging station 222 and then to the discharging station 223, thereby reducing manual intervention and improving work efficiency.

[0065] It should be noted that the first rotation driving member 26 may be a driving motor in the prior art.

[0066] Furthermore, a second positioning mechanism 24 is provided on the bracket 21 near the discharge station 223, and the placement frame 200 moved to the discharge station 223 is positioned at the discharge station 223 by the second positioning mechanism 24. It can be understood that by providing the second positioning mechanism 24, the placement frame 200 can be positioned at the discharge station 223, ensuring the accuracy of the position of the placement frame 200, thereby facilitating the stacking mechanism to accurately clamp the placement frame 200 with the piston placed thereon for stacking, and the reliability is better.

[0067] In one embodiment, the first positioning mechanism 23 and the second positioning mechanism 24 each include two telescopic driving members and two positioning blocks. The two telescopic driving members are respectively arranged on both sides of the bracket 21 along the second horizontal direction, and the output ends of the two telescopic driving members are arranged facing each other. The two positioning blocks are respectively arranged at the output ends of the two telescopic driving members. The two telescopic driving members can respectively drive the two positioning blocks to move toward or away from each other so as to respectively abut or separate from the two corners of the placement frame 200.

[0068] Furthermore, the first positioning mechanism 23 includes two first telescopic driving members 231 and two first positioning blocks 232. The two first telescopic driving members 231 are respectively arranged on both sides of the bracket 21 along the second horizontal direction, and the output ends of the two first telescopic driving members 231 are arranged facing each other. The two first positioning blocks 232 are respectively arranged at the output ends of the two first telescopic driving members 231. The two first telescopic driving members 231 can respectively drive the two first positioning blocks 232 to move toward or away from each other, so as to respectively abut or separate from the two corners of the placement frame 200 located at the discharge station 222.

[0069] It can be understood that the first positioning mechanism 23 is arranged on the bracket 21 near the discharge station 222, and is used to block the placement frame 200 located at the discharge station 222 from moving toward the discharge station 223. In actual use, when the placement frame 200 moves from the feeding station 221 to the discharge station 222, the two first telescopic driving members 231 respectively drive the two first positioning blocks 232 to move toward each other, so that the two first positioning blocks 232 can respectively abut against the two corners of the placement frame 200, thereby positioning the placement frame 200 at the discharge station 222, so that the mechanical arm 41 can accurately place the piston after detection in the placement frame 200. In addition, by telescopically driving the first positioning block 232 to move through the first telescopic driving member 231, when the first positioning block 232 abuts against the corners of the placement frame 200, it can also be adjusted to correct the placement position and posture of the placement frame 200, thereby improving the accuracy of the piston framing.

[0070] Specifically, the two first telescopic driving members 231 are arranged diagonally, so that the two first positioning blocks 232 can respectively abut against two diagonally opposite corners of the placement frame 200 located at the unloading station 222 .

[0071] Furthermore, the second positioning mechanism 24 includes two second telescopic driving members 241 and two second positioning blocks 242. The two second telescopic driving members 241 are respectively arranged on both sides of the bracket 21 along the second horizontal direction, and the output ends of the two second telescopic driving members 241 are arranged facing each other. The two second positioning blocks 242 are respectively arranged at the output ends of the two second telescopic driving members 241. The two second telescopic driving members 241 can respectively drive the two second positioning blocks 242 to move toward or away from each other, so as to respectively abut or separate from the two corners of the placement frame 200 located at the discharge station 222.

[0072] It can be understood that the first positioning mechanism 23 and the second positioning mechanism 24 have the same principle and will not be elaborated here. The second positioning mechanism 24 is used to position the placement frame 200 located at the discharge station 222, so that the stacking mechanism can accurately clamp the placement frame 200 with the piston placed thereon; similarly, the second positioning mechanism 24 also has the function of correcting the placement position and posture of the placement frame 200.

[0073] Specifically, the two second telescopic driving members 241 are also arranged diagonally, so that the two second positioning blocks 242 can respectively abut against two diagonally opposite corners of the placement frame 200 located at the discharge station 223.

[0074] It should be noted that the two telescopic driving members may adopt telescopic cylinders or oil cylinders in the prior art.

[0075] In one embodiment, the opposite side of the two first positioning blocks 232 and the opposite side of the two second positioning blocks 242 are provided with notches that match the corner shape of the placement frame 200. It can be understood that by providing the notches so as to accurately abut against the corners of the placement frame 200, the position of the placement frame 200 can be quickly located and corrected.

[0076] In one embodiment, the bracket 21 includes a support platform 211 and two support frames 212, the two support frames 212 are respectively connected to the two ends of the support platform 211 along the first horizontal direction, the two rotating shafts 25 are respectively arranged on the two support frames 212, and the first rotating driving member 26 is arranged on one of the support frames 212; the top and bottom of the transmission belt 22 are respectively abutted against the opposite sides of the support platform 211 along the vertical direction, and the two first telescopic driving members 231 are both installed on the support platform 211.

[0077] It can be understood that the support platform 211, as the main bearing component, provides a basis for the smooth operation of the transmission belt 22, ensuring that the transmission belt 22 will not shake or tilt during the process of conveying the placement frame 200. The two support frames 212 are respectively connected to the two ends of the support platform 211, further enhancing the rigidity and stability of the overall structure. In addition, the top and bottom of the transmission belt 22 are respectively abutted against the opposite sides of the support platform 211 along the vertical direction. Such a design can effectively limit the vertical displacement of the transmission belt 22, prevent it from being offset or loosened during operation, so that when the placement frame 200 is placed on the transmission belt 22, the transmission belt 22 will not be bent downward, and the pressure of the placement frame 200 on the transmission belt 22 is directly dispersed to the support platform 211, ensuring the smoothness of transportation and improving the transmission efficiency and reliability.

[0078] In one embodiment, each support frame 212 includes a cross bar 2121 and two vertical bars 2122, and the two ends of the cross bar 2121 along the second horizontal direction are respectively connected to the tops of the two vertical bars 2122; the two ends of each rotating shaft 25 are respectively connected to the corresponding two vertical bars 2122 through a hinge seat, and the first rotating drive member 26 is arranged on the corresponding vertical bar 2122.

[0079] It can be understood that the frame structure composed of the horizontal rod 2121 and the vertical rod 2122 provides a solid mechanical support for the entire support frame 212, ensuring its stability and durability when bearing weight and external forces. The two ends of each rotating shaft 25 are connected to the corresponding two vertical rods 2122 through a hinge seat, thereby ensuring the connection stability of the rotating shaft 25 and realizing the stable rotation of the rotating shaft 25.

[0080] Furthermore, the support platform 211 includes two connecting rods 2111 and a plurality of fixed rods 2112. The two connecting rods 2111 are arranged at intervals along the second horizontal direction. The plurality of fixed rods 2112 are arranged at intervals and are all located between the two connecting rods 2111. The two ends of each connecting rod 2111 along the first horizontal direction are respectively connected to the corresponding two vertical rods 2122. The two ends of each fixed rod 2112 along the first horizontal direction are respectively connected to the corresponding two horizontal rods 2121. The two first telescopic driving members 231 are respectively installed on the two connecting rods 2111.

[0081] It can be understood that by connecting the connecting rod 2111 with the vertical rod 2122, and connecting the fixed rod 2112 with the horizontal rod 2121, the pressure can be effectively and evenly distributed on the support frame 212, thereby reducing local stress concentration and enhancing the strength of the overall structure. In addition, the structure in which two connecting rods 2111 and multiple fixed rods 2112 are arranged at intervals saves the material requirements of the support platform 211, and reduces the production cost of the support platform 211 and the subsequent maintenance cost.

[0082] Furthermore, a plurality of transmission belts 22 are provided, and the plurality of transmission belts 22 are arranged at intervals along the second horizontal direction, and the number of the transmission belts 22 and the fixed rods 2112 are consistent and arranged one-to-one, and the top and bottom of each transmission belt 22 respectively abut against the opposite sides of the corresponding fixed rod 2112 along the vertical direction.

[0083] It can be understood that the transmission belt 22 and the fixing rod 2112 are arranged in a one-to-one correspondence, which can effectively ensure the stability of each transmission belt 22, effectively bear the pressure of the placement frame 200 placed on the transmission belt 22, ensure the stable operation of the transmission belt 22, enhance the stability during transportation, and facilitate subsequent maintenance.

[0084] Specifically, each rotating belt is transmission-connected to the two rotating shafts 25, and each transmission belt 22 runs synchronously.

[0085] Furthermore, the heights of the two connecting rods 2111 are higher than the heights of the fixing rods 2112. It can be understood that the placement frame 200 is mainly supported on the transmission belt 22 located on the fixing rods 2112, and the heights of the two connecting rods 2111 are higher than the fixing rods 2112, which is equivalent to the connecting rods 2111 blocking the two sides of the placement frame 200 along the second horizontal direction, thereby preventing the placement frame 200 from falling from the support platform 211, and having better reliability.

[0086] In one embodiment, multiple transmission belts 22 are evenly spaced, and multiple transmission wheels 251 are sleeved on each rotating shaft 25. The number of transmission wheels 251 is the same as that of transmission belts 22 and they are arranged one by one. Each transmission belt 22 is connected to two corresponding rotating wheels. It can be understood that the even spacing between multiple transmission belts 22 ensures that the load of the placement frame 200 is evenly distributed during the transportation process; the transmission wheels 251 and the transmission belts 22 are arranged one by one, which ensures that each transmission belt 22 can accurately cooperate with the corresponding transmission wheel 251, avoiding the deviation or slipping of the transmission belt 22, and improving the accuracy and stability of transmission.

[0087] In one embodiment, a plurality of baffles 213 are further disposed on the top of the cross bar 2121 near the discharging station 223 . The plurality of baffles 213 are spaced apart along the second horizontal direction, and the plurality of baffles 213 protrude from the top surface of the transmission belt 22 .

[0088] It can be understood that by providing multiple baffle bars 213 on the top of the cross bar 2121 near the discharge station 223, and the multiple baffle bars 213 protrude from the top surface of the transmission belt 22, when the placement frame 200 moves on the transmission belt 22 to the discharge station 223, the baffle bars 213 can block the placement frame 200 to prevent the placement frame 200 from falling out directly.

[0089] It should be noted that, in actual use, the placement frame 200 moved to the discharge station 223 is first blocked by the blocking rod 213 to prevent it from falling out, and then the placement frame 200 is positioned by the second positioning mechanism 24 to correct the position of the placement frame 200.

[0090] In one embodiment, the conveying device 2 also includes two rotary downward pressing cylinders, which are arranged between any two adjacent fixed rods 2112, and the output end of each rotary downward pressing cylinder is connected to a blocking block; one of the rotary downward pressing cylinders is arranged on the side of the feeding station 221 close to the discharging station 222, and the other rotary downward pressing cylinder is arranged on the side of the discharging station 222 close to the discharging station 223, and the two rotary downward pressing cylinders can respectively drive the two blocking blocks to protrude from the top surface of the transmission belt 22.

[0091] It can be understood that one of the rotary pressing cylinders is arranged on the side of the feeding station 221 close to the unloading station 222, and when it drives the corresponding blocking block to protrude from the top surface of the transmission belt 22, it can block the placement frame 200 located at the feeding station 221 from moving toward the unloading station 222; the other rotary pressing cylinder is arranged on the side of the unloading station 222 close to the discharging station 223, and when it drives the corresponding blocking block to protrude from the top surface of the transmission belt 22, it can block the placement frame 200 located at the unloading station 222 from moving toward the discharging station 223; it should be noted that the rotary pressing cylinder can adopt the rotary pressing cylinder in the prior art, and the output end of the rotary pressing cylinder can drive the blocking block to be higher than the top surface of the transmission belt 22 after rotation, and can drive the blocking block to be lower than the top surface of the transmission belt 22 after resetting.

[0092] Further, for the sake of convenience of explanation, the rotary pressing cylinder arranged on the side of the feeding station 221 close to the discharging station 222 is the first rotary pressing cylinder, and the output end of the first rotary pressing cylinder is connected to the first blocking block 214; the rotary pressing cylinder arranged on the side of the discharging station 222 close to the discharging station 223 is the second rotary pressing cylinder, and the output end of the second rotary pressing cylinder is connected to the second blocking block 215.

[0093] In actual use, when the discharge station 222 does not have the placement frame 200, the first rotating downward-pressing cylinder makes the first blocking block 214 not protrude from the top surface of the transmission belt 22, and the placement frame 200 placed at the feeding station 221 by the clamping mechanism 12 can be normally driven by the transmission belt 22 and moved to the discharge station 222. At this time, the second rotating downward-pressing cylinder makes the second blocking block 215 protrude from the top surface of the transmission belt 22 to prevent the placement frame 200 from moving directly to the discharge station 223 after moving to the discharge station 222. When the second blocking block 215 successfully blocks the placement frame 200 at the discharge station 222, the placement frame 200 is positioned and the position of the placement frame 200 is corrected by the first positioning mechanism 23 to carry out the subsequent piston framing process. When there is a placement frame 200, continue to clamp a placement frame 200 through the clamping mechanism 12 and place it in the feeding station 221. At this time, the first rotating downward pressure cylinder makes the first blocking block 214 protrude from the top surface of the transmission belt 22, thereby blocking the placement frame 200 from moving toward the discharge station 222; at this time, there are placement frames 200 on both the feeding station 221 and the discharge station 222 on the transmission belt 22. When the placement frame 200 at the discharge station 222 is full of pistons, the two blocking blocks no longer block the corresponding placement frame 200, and the first positioning structure is no longer positioning the placement frame 200. At this time, both placement frames 200 can move with the transmission belt 22. When the placement frame 200 at the discharge station 222 is moved out, the second blocking block 215 rises and continues to block the placement frame 200 that is about to reach the discharge station 222. It can be seen that, through the cooperation of the above two rotating downward-pressing cylinders, it is possible to continuously deliver the empty placement frame 200 to the discharge station 222, thereby improving the piston frame installation efficiency.

[0094] In one embodiment, the conveying device 2 further includes a first proximity sensor 27 , which is disposed on the connecting rod 2111 at a position close to the discharge station 222 , and the two rotary downward-pressing cylinders are both electrically connected to the first proximity sensor 27 .

[0095] It can be understood that by setting the first proximity sensor 27, when the first proximity sensor 27 senses that the placement frame 200 is close to the discharge station 222, the two rotating downward pressing cylinders are controlled to move, thereby driving the two blocking blocks to protrude from the top surface of the transmission belt 22 to block the placement frame 200.

[0096] Furthermore, a second proximity sensor 28 is also provided on the support table 211. The second proximity sensor 28 is arranged near the discharge station 222. Specifically, the second proximity sensor 28 is arranged on one of the connecting rods 2111. The second proximity sensor 28 is electrically connected to the two first telescopic driving members 231. When the second proximity sensor 28 senses that a placement frame 200 is located at the discharge station 222, the two first telescopic driving members 231 are controlled to drive the corresponding two first positioning blocks 232 to move toward each other to position the placement frame 200.

[0097] It should be noted that the first proximity sensor 27 is electrically connected to the two rotary downward pressing cylinders through a PLC controller, and the second proximity sensor 28 is also electrically connected to the two first telescopic driving members 231 through the PLC controller.

[0098] See also Figure 8-Figure 10 In one embodiment, the stacking mechanism 51 includes a support seat 511 and a slide seat 512 movably arranged on the support seat 511, and a lifting mechanism 513 is arranged on the slide seat 512. The lifting mechanism 513 is located on one side of the support seat 511 along the first horizontal direction, and a gripper 515 is arranged at the bottom of the lifting mechanism 513, and the lifting mechanism 513 can drive the gripper 515 to rise and fall; a stacking station and a material grabbing station are provided on the side of the support seat 511 where the gripper 515 is located, and the stacking station and the material grabbing station are arranged at intervals along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction; the slide seat 512 can move along the second horizontal direction to drive the gripper 515 to move between the stacking station and the material grabbing station through the lifting mechanism 513; the material receiving mechanism 52 is arranged corresponding to the stacking station, and the gripper 515 is used to grab the placement frame 200 at the material grabbing station and stack the placement frame 200 on the material receiving mechanism 52.

[0099] It can be understood that the position of the gripper 515 can be quickly adjusted through the slide 512 and the lifting mechanism 513 to ensure that the gripper 515 moves accurately and grabs the support frame 212, and transfers the support frame 212 to be stacked on the material receiving mechanism 52, ensuring that the stacking position and method of each placement frame 200 are consistent, thereby reducing manual labor intensity and improving the stacking efficiency of the placement frame 200.

[0100] In actual use, the slide 512 is adjusted to drive the gripper 515 to move in the horizontal direction. When reaching the stacking station or the material grabbing station, the lifting mechanism 513 is used to adjust the height of the gripper 515, so as to facilitate the stacking of the placement frame 200 or the clamping of the placement frame 200.

[0101] It should be noted that the material grabbing station is arranged corresponding to the material discharging station 223 of the conveying mechanism. When the gripper 515 is located at the material grabbing station, the lifting mechanism 513 controls the gripper 515 to lift vertically to reach the material discharging station 223 to grab the placement frame 200 equipped with the piston.

[0102] In one embodiment, the stacking device 5 also includes an auxiliary positioning mechanism 53, which includes an installation frame 531 and a movable seat 532. The installation frame 531 is arranged on the side of the material receiving mechanism 52 away from the support seat 511, and the movable seat 532 is movably arranged on the side of the installation frame 531 facing the material receiving mechanism 52, and the movable seat 532 can move vertically relative to the installation frame 531. Two limit blocks 5325 are provided on the side of the movable seat 532 facing the material receiving mechanism 52, and the two limit blocks 5325 are respectively used to abut against the opposite sides of the placement frame 200 stacked on the material receiving mechanism 52 to position the placement frame 200.

[0103] It can be understood that the mounting frame 531 of the auxiliary positioning mechanism 53 is fixed on the ground to maintain good stability. By moving the movable seat 532 vertically on the mounting frame 531, the two limit blocks 5325 can be used to cooperate with the placement frames 200 of different heights. According to the different stacking heights of the placement frames 200, the position of the movable seat 532 is adjusted so that the two limit blocks 5325 cooperate with the topmost placement frame 200, thereby keeping the stacked multiple placement frames 200 balanced and preventing shaking, so that the gripper 515 can continue to stack the placement frames 200 with better reliability.

[0104] Furthermore, the mounting frame 531 forms an mounting space 5311 having an opening, and the opening is located on a side of the mounting frame 531 facing the material receiving mechanism 52. Two rotating rods 5312 extending along the second horizontal direction are rotatably connected in the mounting space 5311, and the two rotating rods 5312 are arranged at intervals along the vertical direction. Two sprockets 5313 are respectively provided at corresponding positions on the two rotating rods 5312, and the two sprockets 5313 are connected in transmission through a transmission chain 5314. A second rotating driving member connected in transmission with one of the rotating rods 5312 is provided on the mounting frame 531, and the movable seat 532 is connected to the transmission chain 5314; the second rotating driving member can drive the corresponding rotating rod 5312 to rotate to drive the sprocket 5313 to rotate, so as to drive the movable seat 532 to move vertically through the transmission chain 5314.

[0105] It can be understood that the combination of the sprocket 5313 and the transmission chain 5314 provides a stable transmission method, ensuring the stability and accuracy of the moving seat 532 during the vertical movement. The design of the transmission chain 5314 can effectively transmit power and prevent the moving seat 532 from sliding or slipping relative to the transmission chain 5314.

[0106] It should be noted that the second rotation driving member may be a driving motor in the prior art.

[0107] In one embodiment, the movable seat 532 includes a horizontal plate 5321 and a vertical plate 5322 that are connected to each other, the horizontal plate 5321 is located on the side of the vertical plate 5322 close to the opening, and the vertical plate 5322 is connected to the transmission chain 5314; a guide rod 5315 extending vertically is also provided in the installation space 5311, and the guide rod 5315 is located on the side of the rotating rod 5312 close to the opening, and a through hole is opened on the horizontal plate 5321 for the guide rod 5315 to pass through.

[0108] It can be understood that the guide rod 5315 passes through the through hole on the horizontal plate 5321, providing a stable vertical guide for the movable seat 532, ensuring that it will not deviate or shake during the up and down movement, thereby improving the operation accuracy and stability of the movable seat 532.

[0109] In one embodiment, two extension plates 5323 extending along the first horizontal direction are provided at both ends of the movable seat 532 and on one side facing the material receiving mechanism 52, and the ends of the two extension plates 5323 away from the movable seat 532 both extend out of the installation space 5311, and the length of one extension plate 5323 along the first horizontal direction is greater than the length of the other extension plate 5323 along the first horizontal direction; the ends of the two extension plates 5323 away from the movable seat 532 are both provided with a third telescopic driving member 5324, and the output ends of the two third telescopic driving members 5324 are arranged facing each other, and two limit blocks 5325 are respectively arranged at the output ends of the two third telescopic driving members 5324, and the two third telescopic driving members 5324 can respectively drive the two limit blocks 5325 to move toward or away from each other, so as to respectively abut or separate from the two corners of the placement frame 200 located on the material receiving mechanism 52.

[0110] It can be understood that, by extending the extension plate 5323 out of the installation space 5311 and installing a third telescopic driving member 5324 on the extension plate 5323, the third telescopic driving member 5324 telescopically drives the limit block 5325 to move, thereby abutting against the corners of the placement frame 200 to prevent the stacked multiple placement frames 200 from shaking and further improve the accuracy of stacking.

[0111] It should be noted that the third telescopic driving member 5324 can adopt a telescopic cylinder or oil cylinder in the prior art.

[0112] Specifically, the two limiting blocks 5325 are each provided with a notch on one side facing the other, the notch matching the corner shape of the placement frame 200 .

[0113] In one embodiment, the material receiving mechanism 52 includes a material receiving trolley 521 and a positioning frame 522. The positioning frame 522 encloses a positioning space with an entrance. The entrance is located on the side of the positioning frame 522 away from the material grabbing station. The material receiving trolley 521 has a material receiving plate for stacking the placement frame 200. The material receiving trolley 521 can enter and exit the positioning space from the entrance.

[0114] It should be noted that the material receiving vehicle 521 is the same as the above-mentioned carrying vehicle 111 and can be used interchangeably; the positioning frame 522 has the same structure and function as the above-mentioned fixing frame 112, which will not be described in detail here.

[0115] Furthermore, a third rotary pressing cylinder 5221 is provided near the opening on the positioning frame 522, and a stop block 5222 is connected to the third rotary pressing cylinder 5221. The third rotary pressing cylinder 5221 can make the stop block 5222 be located at the opening to abut against the side of the receiving plate located in the positioning space toward the opening.

[0116] It can be understood that after the output end of the third rotary pressing cylinder 5221 rotates, it can drive the stop block 5222 to block the opening position, thereby preventing the material receiving cart 521 in the positioning space from sliding out of the positioning space, so as to ensure that the placement frame 200 yards can be placed on the material receiving cart 521, with better reliability. When the material receiving cart 521 needs to be moved out, the output end of the third rotary pressing cylinder 5221 is reset, thereby driving the stop block 5222 to leave the opening position.

[0117] Similarly, the fixed frame 112 is also provided with the same third rotary downward-pressing cylinder 5221 and the stop block 5222 for preventing the carrier vehicle 111 in the limited space from sliding out of the limited space, which is more reliable.

[0118] In one embodiment, a mounting plate 514 is provided at the bottom of the lifting mechanism 513, and two grippers 515 are installed at intervals at the bottom of the mounting plate 514. By providing two grippers 515, both grippers 515 can grasp the frame of the placement frame 200, thereby smoothly transferring the placement frame 200 and preventing the piston in the placement frame 200 from falling out.

[0119] In one embodiment, the support seat 511 includes a support column and a support plate 5111 disposed on the top of the support column, and the slide seat 512 is slidably connected to the support plate 5111, and the height of the support plate 5111 is higher than the height of the mounting frame 531. It can be understood that the height of the support plate 5111 is higher, which ensures that each time the gripper 515 moves to the stacking station, it does not interfere with the two limit blocks 5325, and ensures that more placement frames 200 can be stacked on the receiving vehicle 521, which can reduce the number of times the receiving vehicle 521 is replaced, which is conducive to improving the stacking efficiency and reducing the labor intensity.

[0120] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
