Description

Technical Field

[0001] This application relates to the technical field of glass back cover conveying equipment, and in particular to a feeding device for thinning glass mobile phone back covers. Background Technology

[0002] With the continuous development of society, the penetration rate of mobile phones is increasing, and people's demands for mobile phone performance are also rising. Consumers not only pay attention to the hardware and software configuration of mobile phones, but also attach great importance to their appearance. Due to the advantages of glass, such as good corrosion resistance, designability, and good security, more and more glass back covers are being used in mobile phones. Mobile phones with glass back covers have a certain improvement in aesthetics and texture compared to ordinary mobile phones. However, glass mobile phone back covers need to be thinned through laser polishing during the manufacturing process.

[0003] For example, Chinese patent document CN210438061U discloses a mobile phone glass cover plate loading machine including a tray conveyor line, a cover plate picking robot, and a cover plate positioning mechanism. The tray conveyor line is used to transport trays. The cover plate positioning mechanism is installed beside the tray conveyor line. The cover plate picking robot is installed above the tray conveyor line. The cover plate picking robot is used to pick up glass cover plates one by one from the tray and place them onto the cover plate positioning mechanism. The cover plate positioning mechanism has a positioning cavity and includes a pushing device. The positioning cavity is opened when the cover plate picking robot picks up or places glass cover plates. The pushing device extends into the positioning cavity and pushes the glass cover plate tightly when the cover plate picking robot places the glass cover plate into the positioning cavity. The products are arranged sequentially on the upper surface of the conveyor belt. The conveyor belt rotates and moves the products forward. The products are further arranged by the limiting plate to make them more neat. When the products enter the upper surface of the gripping table, they are positioned vertically by the sliding plate and the baffles on both sides. They fall into the gripping groove. At this time, the air pump pressurizes the cylinder, causing the pneumatic claws to extend to the top of the gripping groove. The air pump then pressurizes the pneumatic claws again, causing the claw arms to retract inward and pass through the groove to clamp the two ends of the products.

[0004] In the aforementioned related technologies, the glass cover plates on the conveyor belt are transported to the positioning mechanism by activating the chucks. After the glass cover plates are processed on the positioning mechanism, the chucks remove the processed glass cover plates from the positioning mechanism and place them into the storage rack. Then, the chucks transport the subsequent unprocessed glass cover plates on the conveyor belt to the positioning mechanism for processing. During the glass cover plate transport process, the processed glass cover plates on the positioning mechanism need to be transported to the storage rack before the unprocessed glass cover plates on the conveyor belt can be transported to the positioning mechanism, which will reduce the processing efficiency of the glass cover plates. Summary of the Invention

[0005] This application provides a feeding device for thinning glass mobile phone back covers, aiming to solve the problem of low processing efficiency of glass mobile phone back covers in related technologies.

[0006] The feeding device for thinning glass mobile phone back covers provided in this application adopts the following technical solution:

[0007] A feeding device for thinning glass mobile phone back covers includes a first conveying component, a second conveying component, and a third conveying component disposed within a processing chamber. The processing chamber contains a feeding component for glass mobile phone back covers, on which finished and unfinished glass mobile phone back covers are mounted. The third conveying component includes a gripping component for conveying the glass mobile phone back covers from the feeding component to a mold. The gripping component includes a mounting frame mounted on the third conveying component, a mounting rod rotatably connected to the mounting frame, and multiple sets of suction cups fixed to the mounting rod. The mounting frame is equipped with a feeding motor for driving the mounting rod to rotate. Each set of suction cups includes a first suction cup and a second suction cup, and the first and second suction cups are equipped with multiple nozzles for abutting against the glass mobile phone back cover. The first suction cup is used to convey the finished glass mobile phone back cover from the mold to the feeding component, and the second suction cup is used to convey the unfinished glass mobile phone back cover from the feeding component to the mold.

[0008] By adopting the above technical solution, during the feeding process of the glass mobile phone back cover, the second suction cup adsorbs the unprocessed glass mobile phone back cover. Under the action of the first, second, and third conveying components, the unprocessed glass mobile phone back cover is conveyed to the mold. The glass mobile phone back cover is thinned by the laser grinding device. During the processing of the glass mobile phone back cover on the mold, the first and second suction cups are reset and grip the glass mobile phone back cover on the unloading component. At this time, the glass mobile phone back cover is adsorbed onto the first suction cup. Then, the first suction cup moves the glass mobile phone back cover to the top of the mold. The processing of the glass mobile phone back cover on the mold is completed. The unloading motor drives the mounting rod to rotate, causing the first and second suction cups to rotate to the water... In a flat position, the first suction cup is at the top and the second suction cup is at the bottom. The finished glass phone back cover on the mold is adsorbed onto the second suction cup. After the finished glass phone back cover is completely separated from the mold, the mounting rod rotates 180 degrees, causing the first suction cup to rotate to the bottom and the second suction cup to rotate to the top. The unfinished glass phone back cover on the first suction cup is placed on the mold. Then, the finished glass phone back cover is conveyed to the feeding assembly through the first suction cup. At the same time, the unfinished glass phone back cover on the feeding assembly is conveyed to the top of the mold to continue the next round of conveying. In this way, when the finished glass phone back cover is removed, the unfinished glass phone back cover can be conveyed to the mold, improving the processing efficiency of glass phone back covers.

[0009] Optionally, the feeding assembly includes a mounting frame disposed inside the processing box and feeding rods fixed on the mounting frame. Each set of suction cup components corresponds to four feeding rods. The four feeding rods have the same structure, with two feeding rods disposed at the top and two feeding rods disposed at the bottom. The distance between the two feeding rods at the bottom is less than the distance between the two feeding rods at the top.

[0010] By adopting the above technical solution, the unprocessed glass mobile phone back cover and the processed glass mobile phone back cover can be limited by the action of four feeding rods.

[0011] Optionally, the feeding assembly further includes feeding rings fixed on feeding rods. Each feeding rod is provided with multiple feeding rings, which are arranged along the length of the feeding rod. Each feeding ring is provided with a feeding groove, and the glass mobile phone back cover is placed in the groove.

[0012] By adopting the above technical solution, the glass back cover of the mobile phone can be limited by the feeding trough. During the limiting process, the glass back cover of the mobile phone can be prevented from contacting each other, thus reducing the risk of the glass back cover of the mobile phone being crushed.

[0013] Optionally, the suction cup components are provided in multiple sets, with each set of suction cup components corresponding to four feeding rods.

[0014] By adopting the above technical solution, multiple suction cup components can be set up to feed multiple glass mobile phone back covers, thereby improving the feeding efficiency of glass mobile phone back covers.

[0015] Optionally, the second suction cup is provided with a support assembly, which includes a support frame fixed on the second suction cup, a support rod disposed on the support frame, and a support plate slidably connected to the support rod. The support plate is used to support the unprocessed glass mobile phone back cover to be adsorbed. When the second suction cup is inserted between the two feeding rods, the support plate abuts against the surface of the unprocessed glass mobile phone back cover.

[0016] By adopting the above technical solution, when the second suction cup needs to transport the unprocessed glass phone back cover, the second suction cup is inserted between the two feeding rods, and the suction nozzle on the second suction cup abuts against the glass phone back cover. At the same time, the support plate is positioned above the glass phone back cover. Then, by moving the support plate, it is inserted into the feeding groove and abuts against the surface of the glass phone back cover. The position of the support plate is defined. Then, the second suction cup moves closer to the glass phone back cover, so that the suction nozzle tightly abuts against the surface of the glass phone back cover, making it easier for the glass phone back cover to adhere to the suction nozzle. Through the setting of the support plate, the support plate can support the glass phone back cover during the compression process of the suction nozzle, thereby reducing the breakage of the glass phone back cover.

[0017] Optionally, the support rod is provided with a control assembly for moving the support plate. The control assembly includes a control plate slidably connected to the support rod, a support spring sleeved on the support rod, and a control cylinder fixed on the control plate. The cylinder body of the control cylinder is fixed on the control plate, the piston rod is fixed on the support plate, one end of the support spring is fixed on the support frame, and the other end is fixed on the control plate.

[0018] By adopting the above technical solution, when the support plate is needed to support the glass back cover of the mobile phone, the control cylinder drives the support plate to move. The support plate moves into the feeding groove and abuts against the surface of the glass back cover of the mobile phone. After the glass back cover of the mobile phone is taken out from the feeding groove, the control cylinder drives the support plate to move in the opposite direction, so that the support plate and the glass back cover of the mobile phone are misaligned.

[0019] Optionally, the first conveying assembly includes two first guide rails fixed in the processing box, a first screw rotatably connected to the first guide rails, and a first conveying motor fixed to the second guide rail. The first conveying motor is fixedly connected to the first screw, and the first screw is threadedly connected to the second conveying assembly. When the first screw rotates, it drives the second conveying assembly to slide along the length direction of the first guide rail.

[0020] Optionally, the second conveying assembly includes a second guide rail fixed in the processing box, a second screw rotatably connected to the second guide rail, a second conveying motor fixed to the second guide rail, and a second slider slidably connected to the first guide rail. The second slider passes through the first screw and is threadedly connected to the first screw. The second conveying motor is fixedly connected to the second screw. The second screw is threadedly connected to the third conveying assembly. When the second screw rotates, it drives the third conveying assembly to slide along the length direction of the second guide rail.

[0021] Optionally, the third conveying assembly includes a third slider slidably connected to the second guide rail, a third guide rail fixed to the third slider, and a third screw rotatably connected to the third guide rail. The third slider passes through the second screw and is threadedly connected to the second screw. A third conveying motor is fixedly installed on the third guide rail, and the output shaft of the third conveying motor is fixedly connected to the third screw.

[0022] Optionally, the width of the first suction cup and the second suction cup is smaller than the width of the glass phone back cover.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Once the glass back cover of the phone is processed on the mold, the feeding motor drives the mounting rod to rotate, causing the first and second suction cups to rotate to a horizontal position, with the first suction cup at the top and the second suction cup at the bottom. The processed glass back cover is then adsorbed onto the second suction cup. After the processed glass back cover is completely separated from the mold, the mounting rod rotates 180 degrees, causing the first suction cup to rotate to the bottom and the second suction cup to rotate to the top. The unprocessed glass back cover on the first suction cup is then placed on the mold. The processed glass back cover is then conveyed to the feeding assembly through the first suction cup. At the same time, the unprocessed glass back cover on the feeding assembly is conveyed to the top of the mold for the next round of conveying. This allows the unprocessed glass back cover to be conveyed to the mold while the processed glass back cover is being removed, improving the processing efficiency of the glass back cover.

[0025] 2. When the second suction cup needs to transport the unprocessed glass phone back cover, the second suction cup will be inserted between the two feeding rods, the support plate will be inserted into the feeding groove, and the support plate will abut against the surface of the glass phone back cover. The position of the support plate is limited, and the second suction cup moves towards the glass phone back cover, so that the suction nozzle is tightly abutted against the surface of the glass phone back cover. During the compression of the suction nozzle, the support plate can support the glass phone back cover and reduce the breakage of the glass phone back cover. Attached Figure Description

[0037] The following combination Figures 1-10 This application will be described in further detail.

[0038] Example 1:

[0039] This application discloses a feeding device for thinning glass mobile phone back covers. (Refer to...) Figures 1 to 7 A feeding device for thinning glass mobile phone back covers includes a first conveying component 1, a second conveying component 2, and a third conveying component 3 disposed within a processing box, and a gripping component 4 disposed on the third conveying component 3. The first conveying component 1 is used to drive the second conveying component 2, the third conveying component 3, and the gripping component 4 to move along the Y-axis direction. The second conveying component 2 is used to drive the third conveying component 3 and the gripping component 4 to move along the X-axis direction. The third conveying component 3 is used to drive the gripping component 4 to move along the Z-axis direction. The gripping component 4 is used to fix the glass mobile phone back cover. At the same time, the fixed glass mobile phone back cover is conveyed into the mold through the first conveying component 1, the second conveying component 2, and the third conveying component 3. Then, the glass mobile phone back cover in the mold is thinned by laser polishing.

[0040] The first conveying assembly 1 includes two first guide rails 11 fixed in the processing box, a first screw rotatably connected to the first guide rails 11, and a first conveying motor 13 fixed to the second guide rail 21. The first conveying motor 13 is fixedly connected to the first screw, and the first screw is threadedly connected to the second conveying assembly 2. When the first screw rotates, it will drive the second conveying assembly 2 to slide along the length direction of the first guide rail 11.

[0041] The second conveying assembly 2 includes a second guide rail 21 fixed inside the processing box, a second screw rotatably connected to the second guide rail 21, a second conveying motor 23 fixed to the second guide rail 21, and a second slider 24 slidably connected to the first guide rail 11. The second slider 24 passes through the first screw and is threadedly connected to the first screw. The second conveying motor 23 is fixedly connected to the second screw. The second screw is threadedly connected to the third conveying assembly 3. When the second screw rotates, it drives the third conveying assembly 3 to slide along the length direction of the second guide rail 21. In this embodiment, the first guide rail 11 and the second guide rail 21 are arranged perpendicularly. The first guide rail 11 is arranged along the Y-axis direction, and the second guide rail 21 is arranged along the X-axis direction.

[0042] The third conveying assembly 3 includes a third slider 31 slidably connected to the second guide rail 21, a third guide rail 32 fixed to the third slider 31, and a third screw 33 rotatably connected to the third guide rail 32. The third slider 31 passes through the second screw and is threadedly connected to it. A third conveying motor 34 is fixedly mounted on the third guide rail 32. The output shaft of the third conveying motor 34 is fixedly connected to the third screw 33. The third conveying motor 34 drives the third screw 33 to rotate. The gripping assembly 4 is connected to the third screw 33, and the third screw 33 drives the gripping assembly 4 to slide along the length direction of the third guide rail 32. In this embodiment, the third guide rail 32 is arranged along the Z-axis.

[0043] The gripping component 4 includes a mounting bracket 41 slidably connected to the third guide rail 32, a mounting rod 42 rotatably connected to the mounting bracket 41, and multiple sets of suction cup components 43 fixed to the mounting rod 42. Each set of suction cup components 43 includes a first suction cup 431 and a second suction cup 432, and multiple suction nozzles 433 are provided on the first suction cup 431 and the second suction cup 432. In this embodiment, four sets of suction cup components 43 are provided on the mounting rod 42, which can feed four glass mobile phone back covers at a time. The suction cup components 43 are connected to an air pump through a connecting pipe. When the air pump is working, it can draw air from the suction cup components 43 and then suck the glass mobile phone back covers onto the suction cup components 43. The glass mobile phone back covers fixed on the suction cup components 43 are transported by the first conveying component 1, the second conveying component 2, and the third conveying component 3, and finally the feeding of the glass mobile phone back covers can be completed. A feeding motor 54 is provided on the mounting frame 41. The output shaft of the feeding motor 54 is fixedly connected to the mounting rod 42. The feeding motor 54 can drive the mounting rod 42 to rotate, thereby adjusting the position of the first suction cup 431 and the second suction cup 432.

[0044] A feeding assembly 5 is provided inside the processing box. The feeding assembly 5 is detachably connected to the processing box. The feeding assembly 5 is equipped with processed glass mobile phone back covers and unprocessed glass mobile phone back covers. The second suction cup 432 is used to transport the unprocessed glass mobile phone back covers on the feeding assembly 5 into the mold. The first suction cup 431 can transport the processed glass mobile phone back covers on the mold into the feeding assembly 5. After the unprocessed glass mobile phone back covers in the feeding assembly 5 are processed, the feeding assembly 5 is filled with processed glass mobile phone back covers. Finally, the feeding assembly 5 is removed from the processing box, and another feeding assembly 5 and multiple unprocessed glass mobile phone back covers placed on the feeding assembly 5 are placed into the processing box to facilitate subsequent material loading.

[0045] The feeding assembly 5 includes a feeding rack 51 disposed inside the processing box, feeding rods 52 fixed on the feeding rack 51, and feeding rings 53 fixed on the feeding rods 52. Each feeding rod 52 is provided with multiple feeding rings 53, which are arranged along the length of the feeding rod 52. Each feeding ring 53 is provided with a feeding groove 55. Each set of suction cup components 43 corresponds to four feeding rods 52. The four feeding rods 52 have the same structure. Two feeding rods 52 are located at the top, and two feeding rods 52 are located at the bottom. The distance between the two lower feeding rods 52 is smaller than the distance between the two upper feeding rods 52. The two upper feeding rods 52 limit the two sides of the glass mobile phone back cover in the feeding groove 55, and the two lower feeding rods 52 support the glass mobile phone back cover in the feeding groove 55, so that the suction cup component 43 can adsorb the glass mobile phone back cover in the feeding groove 55. The material feeding slot 55 allows for spacing between adjacent glass phone back covers, and the glass phone back covers can be set vertically, reducing compression.

[0046] In this embodiment, the width of the first suction cup 431 and the second suction cup 432 is smaller than the width of the glass phone back cover, which facilitates the insertion of the first suction cup 431 from above between the two upper feeding rods 52. Since multiple unprocessed glass phone back covers are inserted between each pair of adjacent feeding rods 52, when the first suction cup 431 and the second suction cup 432 are inserted between the two feeding rods 52, the mounting bracket 41 drives the first suction cup 431 and the second suction cup 432 to move towards the unprocessed glass phone back cover, so that the suction nozzle 433 abuts against the surface of the glass phone back cover, and at the same time, the suction nozzle 433 is in a slightly compressed state. Then, the air pump works to generate negative pressure in the suction nozzle 433, and the glass phone back cover is adsorbed onto the second suction cup 432.

[0047] Under the action of the first conveying assembly 1, the second conveying assembly 2, and the third conveying assembly 3, the mounting rod 42 first moves the first suction cup 431 and the second suction cup 432 upward, causing the glass phone back cover to detach from the feeding groove 55. Then, it moves towards the mold. The mounting rod 42 rotates, causing the first suction cup 431 and the second suction cup 432 to rotate from a vertical position to a horizontal position, placing the unprocessed glass phone back cover on the mold for processing. Simultaneously, the gripping assembly 4 resets, adsorbing the unprocessed glass phone back cover in the feeding groove 55. When the unprocessed glass phone back cover moves above the mold, the glass phone back cover on the mold is processed. The mounting rod 42 then rotates, causing the first suction cup 431 and the second suction cup 432 to move upward. A suction cup 431 is positioned above a second suction cup 432. The first suction cup 431 adsorbs the processed glass phone back cover on the mold. After the processed glass phone back cover is completely detached from the mold, the mounting rod 42 rotates the first suction cup 431 and the second suction cup 432 180 degrees, so that the second suction cup 432 is below and the first suction cup 431 is above. The second suction cup 432 then places the adsorbed unprocessed glass phone back cover onto the mold. During the processing of the glass phone back cover on the mold, the mounting bracket 41, the second suction cup 432, and the first suction cup 431 are reset, allowing the processed glass phone back cover to be placed between the two feeding rods 52 and limited by the feeding groove 55.

[0048] After the finished glass phone back cover is placed into the feeding groove 55, the first suction cup 431 and the second suction cup 432 move. The second suction cup 432 adsorbs the unfinished glass phone back cover in the feeding groove 55, facilitating the transport of the unfinished glass phone back cover to the top of the mold. Simultaneously, it can remove the finished glass phone back cover from the mold, thereby improving the overall processing efficiency of the glass phone back cover. In this embodiment, a space is provided between the unfinished glass phone back cover and the finished glass phone back cover between the feeding rods 52, allowing the first suction cup 431 and the second suction cup 432 to be inserted. The unfinished glass phone back cover can then be adsorbed onto the second suction cup 432.

[0049] The implementation principle of the feeding device for thinning glass mobile phone back cover according to the embodiment of this application is as follows: under the action of the first conveying component 1, the second conveying component 2 and the third conveying component 3, the gripping component 4 can move along the X-axis, Y-axis and Z-axis. The operation of the first conveying component 1, the second conveying component 2 and the third conveying component 3 is controlled by the controller. During the feeding process, the first suction cup 431 and the second suction cup 432 are inserted between the two feeding rods 52. The second suction cup 432 moves towards the unprocessed glass mobile phone back cover and adsorbs the unprocessed glass mobile phone back cover.

[0050] When the unprocessed glass phone back cover is fixed on the second suction cup 432, the mounting rod 42 drives the first suction cup 431 and the second suction cup 432 to move upward. The unprocessed glass phone back cover detaches from the feeding groove 55 and then moves above the mold. The feeding motor 54 drives the mounting rod 42 to rotate, and the mounting rod 42 drives the first suction cup 431 and the second suction cup 432 to rotate from a vertical position to a horizontal position, placing the unprocessed glass phone back cover on the mold for processing. At the same time, the gripping component 4 resets and adsorbs the unprocessed glass phone back cover in the feeding groove 55. When the unprocessed glass phone back cover moves above the mold, the glass phone back cover on the mold is processed, and the mounting rod 42 rotates. Position the first suction cup 431 above the second suction cup 432. The first suction cup 431 adsorbs the processed glass phone back cover on the mold. After the processed glass phone back cover is completely detached from the mold, the mounting rod 42 drives the first suction cup 431 and the second suction cup 432 to rotate 180 degrees, so that the second suction cup 432 is below and the first suction cup 431 is above. The second suction cup 432 places the adsorbed unprocessed glass phone back cover on the mold. During the processing of the glass phone back cover on the mold, the mounting bracket 41, the second suction cup 432, and the first suction cup 431 are reset, so that the processed glass phone back cover is placed between the two feeding rods 52 and limited by the feeding groove 55.

[0051] After the finished glass phone back cover is placed into the feeding groove 55, the first suction cup 431 and the second suction cup 432 move. The second suction cup 432 adsorbs the unfinished glass phone back cover in the feeding groove 55, facilitating the transport of the unfinished glass phone back cover to the top of the mold. Simultaneously, it can remove the finished glass phone back cover from the mold, thereby improving the overall processing efficiency of the glass phone back cover. In this embodiment, a space is provided between the unfinished glass phone back cover and the finished glass phone back cover between the feeding rods 52, allowing the first suction cup 431 and the second suction cup 432 to be inserted. The unfinished glass phone back cover can then be adsorbed onto the second suction cup 432.

[0052] Example 2:

[0053] The difference from Embodiment 1 is that when adsorbing unprocessed glass mobile phone back covers in the material discharge tank 55, the support component 6 can support the unprocessed glass mobile phone back covers, reducing the risk of breakage of the unprocessed glass mobile phone back covers during the adsorption process.

[0054] Reference Figures 8 to 10A support assembly 6 is provided on the second suction cup 432. The support assembly 6 includes a support frame 61 fixed on the second suction cup 432, a support rod 62 provided on the support frame 61, and a support plate 63 slidably connected to the support rod 62. The support plate 63 is used to support the unprocessed glass mobile phone back cover to be adsorbed. When the second suction cup 432 is inserted between the two feeding rods 52, the support plate 63 abuts against the surface of the unprocessed glass mobile phone back cover. At this time, the unprocessed glass mobile phone back cover is between the second suction cup 432 and the support plate 63. During the movement of the second suction cup 432 toward the unprocessed glass mobile phone back cover, the position of the support plate 63 remains unchanged, which can support the unprocessed glass mobile phone back cover and improve the stability of the unprocessed glass mobile phone back cover.

[0055] A control component 7 is provided on the support rod 62. The control component 7 is used to drive the support plate 63 to move so that the support plate 63 no longer abuts against the unprocessed glass mobile phone back cover. Then the second suction cup 432 will be misaligned with the support plate 63. The control component 7 includes a control plate 71 slidably connected to the support rod 62, a support spring 72 sleeved on the support rod 62, and a control cylinder 73 fixed on the control plate 71. The cylinder body of the control cylinder 73 is fixed on the control plate 71, the piston rod is fixed on the support plate 63, one end of the support spring 72 is fixed on the support frame 61, and the other end is fixed on the control plate 71.

[0056] The suction nozzle 433 on the second suction cup 432 abuts against the surface of the unprocessed glass phone back cover. At this time, the support plate 63 is above the unprocessed glass phone back cover. Then, the control cylinder 73 drives the support plate 63 to move down, so that the support plate 63 abuts against the surface of the unprocessed glass phone back cover. Then, the second suction cup 432 will move closer to the unprocessed glass phone back cover, and the suction nozzle 433 will fit tightly against the unprocessed glass phone back cover. During the process of the second suction cup 432 moving closer to the unprocessed glass phone back cover, the support plate 63 will support the unprocessed glass phone back cover. Since the position of the support plate 63 does not change, the support spring 72 will be compressed. During the process of the second suction cup 432 moving up, the support plate 63 also moves up under the action of the control cylinder 73. At the same time, the support spring 72 pushes the support plate 63 to move away from the second suction cup 432, so that the support plate 63 can support the unprocessed glass phone back cover.

[0057] In other embodiments, multiple support plates 63 can be connected by a connecting plate, and a control cylinder 73 is set.
