The specific structure of the pressing machine can refer to a pressing machine and pressing method disclosed in a Chinese patent with publication number CN112045392B, wherein the pressing machine includes a product fixing plate, a first power mechanism and at least two pressing heads, the pressing heads are arranged above the product fixing plate, and the structure of the pressing heads moving a predetermined first stroke is controlled by the first power mechanism. One of the pressing heads is used for pressing the earpiece, and the remaining pressing heads are used for pressing the buckles. The pressing machine provided by the above patent integrates the processes of pressing the buckles and pressing the earpiece into one machine, realizing semi-automatic production, greatly simplifying the mobile phone assembly process, and greatly improving work efficiency and reducing labor costs.

[0004] When the laminating machine provided by the above patent is used to laminarize a product, the worker places the product to be processed on the product fixing plate, and then the pressure head or pressure plate of the power mechanism descends, and the laminating process of the product is achieved under the action of the pressure head or pressure plate. However, the laminating machine provided by the above patent has some problems. For example, there is only one set of product fixing plates. When the product to be processed is placed on the product fixing plate and squeezed by the pressure head or pressure plate, the product must be removed first, and then another product to be processed must be placed on the product fixing plate.

[0028] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0029] Example 1

[0030] like Figure 1 、 Figure 2 As shown, in order to continuously realize the pressing process of the product and relatively improve the working efficiency of the pressing machine, this embodiment improves the product fixing plate of the existing pressing machine so that the position of the product can be limited by the improved clamping mechanism, and the two sets of clamping components 1 are alternately moved to the bottom of the pressing plate 3 to realize continuous pressing process of the product, thereby improving the efficiency of the product pressing process. The specific technical solution is shown below.

[0031] like Figure 1 Before introducing the clamping mechanism, a brief introduction to the disclosed press machine is provided. Specifically, the press machine comprises a main frame, a pressure system 4, a control system, and a press plate 3. The main frame is the supporting structure of the press machine, providing stability and strength for the entire device. It is generally welded from high-strength steel and possesses sufficient rigidity to withstand the intense pressure during the press process. The frame design should take into account factors such as the equipment's workload, dimensions, and installation requirements. The pressure system 4 can be configured as either a hydraulic or pneumatic system. The hydraulic system consists of a hydraulic pump, a hydraulic cylinder, and hydraulic valves. The hydraulic pump provides high-pressure oil, which is controlled by hydraulic valves in terms of flow and pressure, driving the hydraulic cylinders to generate strong pressure. The pneumatic system consists of an air compressor, an air cylinder, and pneumatic valves. The air compressor provides compressed air, which is controlled by pneumatic valves in terms of flow and pressure, driving the air cylinders to generate pressure. The control system includes an electrical control system and a hydraulic control system. The electrical control system is responsible for controlling various operations and parameters of the press machine, such as pressure, temperature, and time. The hydraulic control system is composed of a PLC (Programmable Logic Controller), a touch screen, sensors, and actuators. It works in conjunction with the hydraulic system to control the direction, pressure, and flow rate of the hydraulic oil, achieving precise control of the press pressure. It also includes hydraulic valves, proportional valves, and amplifiers. The press plate 3 is located at the bottom of the pressure system 4.

[0032] like Figure 2 、 Figure 6 As shown, the clamping mechanism is arranged below the pressing plate 3 and is connected to the main frame. Specifically, the clamping mechanism includes a support plate 2, a connecting assembly 5 and two sets of clamping assemblies 1. The connecting assembly 5 is directly connected to the main frame and is arranged to pass through the support plate 2 at the top. The two sets of clamping assemblies 1 are respectively arranged at both ends of the support plate 2 and can directly support items. When using this clamping mechanism to support items, first stack two items up and down on a clamping assembly 1, such as placing a bracket on an electronic device, rotate the support plate 2, and control the two sets of clamping assemblies 1 to rotate synchronously so that the clamping assembly 1 holding the items moves to the bottom of the pressing plate 3. The pressure system 4 controls the pressing plate 3 to descend and squeeze the two items to connect them. While the pressing plate 3 is squeezing the items, the staff stacks another two items up and down on another clamping assembly 1. After the pressing plate 3 rises, the support plate 2 is controlled to rotate again, and the positions of the two sets of clamping assemblies 1 are adjusted so that the items to be clamped move to the bottom of the pressing plate 3. The pressed items deviate from the pressing plate 3 and are removed by the staff. After removing the product, two other items to be processed are stacked on top of each other and placed on the clamping assembly 1, and the above operation is repeated to achieve efficient processing of batch products, thereby relatively improving production efficiency.

[0033] like Figure 3 、 Figure 4 、 Figure 5As shown, in order to be able to adjust the state of the clamping assembly 1 according to the different sizes of the product, the clamping assembly 1 includes a frame 11 and a plurality of supporting devices 12. A mounting groove 112 is provided on each of the four side walls of the frame 11, and an insert plate 113 is fixedly provided on the inner side of the mounting groove 112. The supporting device 12 includes an adjusting screw 121, a main board 122 and a supporting plate 125. The width and length of the main board 122 are equal to the width and length of the mounting groove 112. A socket 123 is provided on the main board 122, and the main board 122 is set in the mounting groove 112, and the insert plate 113 is inserted into the socket 123. Therefore, with the cooperation of the mounting groove 112 and the insert plate 113, the main board 122 is stably and movably mounted on the frame 11. To control the movement of the mainboard 122, a threaded hole 124 is provided on the mainboard 122. An adjustment screw 121 is threadedly provided through the threaded hole 124. The end of the adjustment screw 121 is connected to the side wall of the mounting groove 112 via a bearing. Therefore, by rotating the adjustment screw 121, the mainboard 122 can be controlled to move within the mounting groove 112, for example, the mainboard 122 protrudes from the mounting groove 112. The support plate 125 is installed at the bottom of the side of the mainboard 122. Therefore, when the clamping assembly 1 is used to support an object, the bottom of the object is directly supported on the support plate 125, such as the edge of an electronic device is placed on the support plate 125, thereby ensuring stable placement of the object. When adjusting the position of the support device 12, a small gap should be left between the mainboard 122 and the object. This allows staff to disassemble and install the object while limiting the stable placement of the object, providing convenience for the continuous processing of batches of objects.

[0034] like Figure 4 、 Figure 7 As shown, in order to ensure stable installation of the frame 11 relative to the support plate 2, snap grooves 23 are provided on both end surfaces of the support plate 2. The snap grooves 23 are provided along the height direction of the support plate 2 and are open on the top surface. A snap plate 111 is fixedly provided on the side surfaces of the two frames 11 that are close to each other. The cross section of the snap plate 111 is the same as that of the snap groove 23. Therefore, the snap plate 111 is installed in the snap groove 23. With the cooperation of the snap plate 111 and the snap groove 23, the frame 11 is stably connected to the support plate 2. In addition, the snap plate 111 can be inserted and removed from the top of the snap groove 23, which facilitates the removal of the frame 11 as needed.

[0035] like Figure 7 、 Figure 8As shown, in order to allow the support plate 2 to be rotatably mounted on the main frame of the press, the connecting assembly 5 includes a coupling shaft 51 and a bottom column 52. The bottom column 52 is mounted on the press and has a threaded groove 57 on its top surface. The coupling shaft 51 is connected through the center hole 21 of the support plate 2 via a bearing, and has a polygonal groove on its top surface and a threaded structure on its bottom. The bottom thread of the coupling shaft 51 is inserted into the bottom column 52. Therefore, under the action of the coupling shaft 51, the support plate 2 is stably mounted above the bottom column 52. In addition, the coupling shaft 51 is connected to the support plate 2 via a bearing. Therefore, in order for the support plate 2 to rotate around the coupling shaft 51, the positions of the two sets of clamping assemblies 1 are adjusted.

[0036] Example 2

[0037] like Figure 7 、 Figure 8 、 Figure 9 As shown, on the basis of Example 1, in order to ensure that the clamping assembly 1 is stably placed after the position is adjusted, a spring 54 and an annular plate 53 are sleeved on the outer side of the base column 52. The annular plate 53 is located above the spring 54, and the spring 54 is in a compressed state. An even number of rods 55 are fixedly provided on the upper side of the annular plate 53, and the even number of rods 55 are evenly distributed along the circumferential direction of the annular plate 53. An even number of slots 22 are provided on the lower side of the support plate 2, and the slots 22 are aligned with the rods 55 one by one, and the rods 55 are inserted into a certain slot 22. Therefore, under the action of the spring 54, the annular plate 53 is arranged in contact with the lower side of the support plate 2, and the rods 55 are inserted into the slots 22, limiting the stable placement of the support plate 2 relative to the base column 52. The arrangement of an even number of rods 55 and an even number of slots 22 facilitates the control of the support plate 2 to rotate 90°, 180°, etc. In order to release the restriction of the support plate 2 and control its rotation, a cam 56 is fixedly provided on the side of the annular plate 53 . The staff can press down the cam 56 to lower the annular plate 53 and at the same time the insertion rod 55 is disengaged from the slot 22 .

[0038] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
