In the following detailed description of the present application, some specific details are described in detail. The present application can also be completely understood without the description of these details by those skilled in the art.

[0038] Unless the context clearly requires otherwise, throughout the description, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to".

[0039] In the description of the present application, it should be understood that the terms "first", "second" and the like are used only for the purpose of description and should not be construed as indicating or implying relative importance. In addition, in the description of the present application, unless otherwise stated, the meaning of "multiple" is two or more.

[0040] Figure 1 is a schematic view of the structure of the pressure maintaining mechanism provided by the embodiment of the present application, Figure 2 is a schematic view of the structure of the pressure maintaining mechanism provided by the embodiment of the present application, Figure 1 and Figure 2As shown, the pressure maintaining mechanism comprises a mounting frame 1, and a jacking assembly 2 and a pressing assembly 3 arranged on the mounting frame 1. It should be noted that the structure of the mounting frame 1 can be set according to actual needs such as cost and space occupation, which is not limited here. Further, Figure 3 is a structural schematic diagram of the jacking assembly provided by the embodiment of the present application, as Figure 3 shown, the jacking assembly 2 comprises a first driving member 21, a support member 22, a bearing member 23 and a connecting member 24. Among them, the support member 22 is arranged on the mounting frame 1 in the vertical direction, and the support member 22 is provided with a guide groove 221 in the obliquely upward direction, and the guide groove 221 is in the structure of an oblique elongated slot. In addition, the top of the support member 22 is provided with the bearing member 23, and the bearing member 23 is used to bear the carrier A with products, so that the jacking assembly 2 jacks up the carrier A, thereby cooperating with the pressing assembly 3 to maintain the pressure of the products on the carrier A. Further, Figure 4 is a cross-sectional schematic diagram of the jacking assembly provided by the embodiment of the present application, as Figure 4 shown, the connecting member 24 comprises a rotating part 241 and a connecting part 242 and a guide part 243 formed by the rotating part 241 extending in different directions, and the rotating part 241, the connecting part 242 and the guide part 243 are spaced apart to form a V-shaped structure. It should be noted that the rotating part 241 is rotatably connected to the mounting frame 1, the connecting part 242 is connected to the first driving member 21, and the guide part 243 is slidably arranged in the guide groove 221. Thus, the first driving member 21 can drive the connecting part 242 to rotate the connecting member 24 through the rotating part 241, so that the guide part 243 can slide in the guide groove 221, and the support member 22 moves up and down under the action of the guide part 243, thereby driving the bearing member 23 to move up and down, that is, driving the carrier A to move up and down.

[0041] In one embodiment, the first driving member 21 is a gas cylinder. Specifically, as Figure 4 shown, the piston rod of the gas cylinder is connected to the connecting part 242 of the connecting member 24, and the cylinder barrel of the gas cylinder is rotatably arranged on the mounting frame 1. Thus, the gas cylinder can drive the support member 22 to move up and down in cooperation with the connecting member 24. It is easy to understand that when the gas cylinder pushes the connecting part 242, the guide part 243 moves obliquely upward along the guide groove 221, and the support member 22 can move downward under the action of the guide part 243 to drive the carrier A on the bearing member 23 to move downward. Correspondingly, when the gas cylinder pulls the connecting part 242, the guide part 243 moves obliquely downward along the guide groove 221, and the support member 22 can move upward under the action of the guide part 243 to jack up the carrier A on the bearing member 23.

[0042] When the carrier 23 is moved upward by the first driving member 21, the connecting member 24 and the support member 22, the pressing assembly 3 is moved toward the carrier 23 to press the products on the carrier A, so as to complete the pressure-keeping work on the products. It is easily understood that when the pressure-keeping work on the products is completed, the first driving member 21 drives the connecting member 24 to make the carrier 23 on the carrier A fall, and meanwhile, the pressing assembly 3 is moved away from the carrier 23 to be separated from the products on the carrier A. Thus, the pressure-keeping mechanism can realize the pressure-keeping work on the products on the carrier A by the cooperation of the jacking assembly 2 and the pressing assembly 3. In an embodiment, the pressure-keeping mechanism can realize the automatic pressure-keeping work when the carrier A is detected between the jacking assembly 2 and the pressing assembly 3 by setting a sensor and a controller.

[0043] As shown in Figure 3 , in an embodiment, the support member 22 is two and is respectively located on both sides of the connecting member 24. Further, Figure 5 is a structural schematic view of the connecting member provided by the embodiment of the present application, as shown in Figure 5 , the connecting member 24 respectively extends toward the two support members 22 to form two guide portions 243 to be respectively slidably connected with the guide grooves 221 on the two support members 22. It is to be noted that by setting the two support members 22 and the two guide portions 243, the driving structural strength of the jacking assembly 2 can be improved, so as to ensure that the jacking assembly 2 can work stably.

[0044] As shown in Figure 5 , in an embodiment, the guide portion 243 is provided with a guide wheel 2431. It is easily understood that the guide wheel 2431 is rollingly arranged in the guide groove 221 to reduce the influence of the frictional resistance in a rolling manner, so as to ensure that the jacking assembly 2 can work smoothly.

[0045] As shown in Figure 5 , in an embodiment, the jacking assembly 2 further comprises a first buffer member 25 and a second buffer member 26. Specifically, the first buffer member 25 and the second buffer member 26 are respectively located below the connecting portion 242 and the guide portion 243. Thus, when the first driving member 21 pulls the connecting member 24, the connecting member 24 is rotated toward the first buffer member 25 until the connecting portion 242 abuts against the first buffer member 25 to be buffered by the first buffer member 25. Correspondingly, when the first driving member 21 pushes the connecting member 24, the connecting member 24 is rotated toward the second buffer member 26 until the guide portion 243 abuts against the second buffer member 26 to be buffered by the second buffer member 26.

[0046] As shown in Figure 3As shown in the figure, in an embodiment, the support 22 is provided with a sliding rail 222. On the other hand, the jacking assembly 2 further comprises a side plate 27, and the side plate 27 is located outside the support 22. Further, the side plate 27 is provided with a sliding block 271 on one side facing the support 22, and the sliding block 271 is in sliding connection with the sliding rail 222. Thus, by providing the sliding rail 222 and the sliding block 271, the movement of the support 22 can be guided and supported.

[0047] As shown in the figure, Figure 3 in an embodiment, the carrier 23 is provided with a relief hole 231. Further, the jacking assembly 2 further comprises a locking member 28 for locking the carrier A, and the locking member 28 is arranged on the top of the support 22 and extends out of the relief hole 231. It should be noted that the locking member 28 is two, and is driven by a double-acting cylinder, so that the carrier A can be locked at the same time, so that the jacking assembly 2 jacks up the carrier A.

[0048] Figure 6 is a structural schematic view of the pressing assembly provided by the embodiment of the present application, as shown in the figure, Figure 6 the pressing assembly 3 comprises a rubber-coated pressing head 31 and a second driving member 32. It is easy to understand that the rubber-coated pressing head 31 is arranged above the carrier 23 in the vertical direction. Further, the second driving member 32 is configured to drive the rubber-coated pressing head 31 to move reciprocatingly in the vertical direction to cooperate with the jacking assembly 2 to complete the pressure maintaining work on the product. It should be noted that the rubber-coated pressing head 31 can avoid damaging the product when contacting the product. In addition, the structure of the rubber-coated pressing head 31 can be set according to the structure of the product to meet the pressure maintaining needs of different products.

[0049] As shown in the figure, Figure 1 and Figure 2 in an embodiment, the pressure maintaining mechanism further comprises a conveying assembly 4. It is easy to understand that the conveying assembly 4 is configured to convey the carrier A between the jacking assembly 2 and the pressing assembly 3, so that the product on the carrier A can be pressure maintained by the jacking assembly 2 and the pressing assembly 3. It should be noted that the conveying assembly 4 can complete the feeding work before pressure maintaining and the discharging work after pressure maintaining.

[0050] Figure 7 is a structural schematic view of the conveying assembly provided by the embodiment of the present application, as shown in the figure, Figure 7As shown in the figure, in an embodiment, the conveying assembly 4 comprises two conveying belts 41 and blocking cylinders 42. Specifically, the two conveying belts 41 are arranged in parallel and maintain a certain distance between them. It is easy to understand that the two conveying belts 41 can be driven by a motor and configured to convey the carriers A synchronously. It should be noted that the conveying assembly 4 can also convey the carriers A by other means such as chain transmission. Further, the blocking cylinders 42 are arranged between the two conveying belts 41 and configured to block the carriers A from moving further when the carriers A move between the jacking assembly 2 and the pressing assembly 3, so that the jacking assembly 2 cooperates with the pressing assembly 3 to pressurize the products on the carriers A. It should be noted that the number and position of the blocking cylinders 42 can be set as needed, for example, one blocking cylinder 42 can be added to block the carrier A loaded with the product to be pressurized when the pressurizing mechanism pressurizes one product.

[0051] As shown in the figure, Figure 7 In an embodiment, the conveying assembly 4 further comprises two fixing members 43. Specifically, the two fixing members 43 are respectively located outside the two conveying belts 41. It should be noted that the fixing members 43 can be driven by a cylinder. Further, the two fixing members 43 are configured to fix the carriers A from the side when the carriers A move between the jacking assembly 2 and the pressing assembly 3, so that the jacking assembly 2 cooperates with the pressing assembly 3 to pressurize the products on the carriers A. It is easy to understand that when the product pressurization is completed, the two fixing members 43 release the carriers A, so that the carriers A continue to be conveyed by the conveying belts 41.

[0052] As shown in the figure, Figure 7 In an embodiment, the conveying assembly 4 further comprises a limiting member 44. Specifically, the limiting member 44 is arranged above the conveying belt 41. It should be noted that the limiting member 44 can be driven by a cylinder. Further, the limiting member 44 is configured to abut the carriers A from an oblique upper side when the carriers A move between the jacking assembly 2 and the pressing assembly 3, so as to limit the carriers A from moving further, so that the jacking assembly 2 can cooperate with the pressing assembly 3 to pressurize the products on the carriers A. It is easy to understand that when the product pressurization is completed, the limiting member 44 disengages from the carriers A, so that the carriers A continue to be conveyed by the conveying belts 41.

[0053] Figure 8 FIG. 1 is a structural schematic diagram of an automatic pressurizing device provided by an embodiment of the present application, Figure 9 FIG. 1 is a structural schematic diagram of an automatic pressurizing device provided by an embodiment of the present application, Figures 8-9As shown, the embodiment of the present application also provides an automatic pressure maintaining device, which comprises a pressure maintaining mechanism, a first discharge channel 5 and a clamping mechanism 6. The structure of the pressure maintaining mechanism is as described above, and will not be repeated here. Further, the clamping mechanism 6 is configured to clamp the carrier A to the first discharge channel 5. Thus, when the product on the carrier A completes the pressure maintaining through the pressure maintaining mechanism, the carrier A loaded with the qualified product can be clamped to the first discharge channel 5 by the clamping mechanism 6 for subsequent work.

[0054] As Figure 9 shown, in an embodiment, the automatic pressure maintaining device further comprises a second discharge channel 7. Specifically, the first discharge channel 5 is located at the side of the conveying assembly 4 to transport the qualified product under the action of the clamping mechanism 6. Correspondingly, the second discharge channel 7 is located at the end of the conveying assembly 4 to directly transport the unqualified product through the conveying assembly 4. Thus, by setting the clamping mechanism 6 and the first discharge channel 5 and the second discharge channel 7, the automatic discharge of the pressure maintained product can be realized. As an optional embodiment, the first discharge channel 5 and the second discharge channel 7 can also be used to transport the unqualified product and the qualified product, respectively. It is easy to understand that the conveying assembly 4 comprises a plurality of blocking cylinders 42. When the product completes the pressure maintaining and the carrier A moves to a predetermined position, one of the blocking cylinders 42 ejects and blocks the carrier A from moving further, so that the clamping mechanism 6 clamps the carrier A.

[0055] Figure 10 is a structural schematic diagram of the clamping mechanism provided by the embodiment of the present application, as Figure 10 shown, in an embodiment, the clamping mechanism 6 comprises a clamping jaw 61 and a third driving member 62. Specifically, the third driving member 62 is configured to drive the clamping jaw 61 to clamp the carrier A to the first discharge channel 5, so as to transport the qualified product. It should be noted that the structure of the clamping jaw 61 can be set according to the structure of the carrier A to adapt to different carriers A. For example, the clamping jaw 61 can be composed of four clamping blocks to adapt to the structure of the carrier A. It should be further noted that the third driving member 62 is a bidirectional cylinder to control the clamping jaw 61 to complete the clamping action.

[0056] As Figure 10As shown, in an embodiment, the clamping mechanism 6 further comprises a fourth driving member 63 and a fifth driving member 64. Specifically, the fourth driving member 63 is configured to drive the third driving member 62 to move in the vertical direction, and the fifth driving member 64 is configured to drive the fourth driving member 63 to move in the horizontal direction. Thus, by providing the fourth driving member 63 and the fifth driving member 64, the movement of the clamping jaw 61 in two dimensions can be achieved, which helps the third driving member 62 to drive the clamping jaw 61 to move the carrier A from the conveying assembly 4 to the first discharge channel 5. As an optional embodiment, the fourth driving member 63 and the fifth driving member 64 are slide table air cylinders, which can ensure the precision requirement of the movement of the clamping jaw 61.
