Description

Technical Field

[0001] The present application relates to the technical field of thermal compression bonding, and in particular to a pressure head structure and thermal compression equipment. Background Art

[0002] Thermocompression bonding is a process in which the adhesive between the first workpiece and the second workpiece is melted by heating, and then a force is applied to the second workpiece to press the second workpiece onto the first workpiece. The second workpiece is generally a thin workpiece such as a sheet or a strip.

[0003] The hot pressing bonding process in the prior art mostly uses a flat pressing head; however, when the portion of the first workpiece to be bonded to the second workpiece is a situation where a straight surface is connected to a curved surface, it is difficult to press the second workpiece onto the curved surface of the first workpiece using a flat pressing head. Even if a contoured pressing head with a curved surface is used, it is difficult to make the second workpiece fully fit the curved surface of the first workpiece, so there is room for improvement. Utility Model Content

[0004] The present application provides a pressing head structure and a hot pressing device for making a second workpiece fully fit onto a portion of a first workpiece having a curved surface or an inclined surface.

[0006] This pressing head structure is such that after the first pressing head presses a part of the second workpiece against the first surface of the first workpiece along the first direction, the second pressing head is driven to move along the second direction by the first driving member so as to press another part of the second workpiece against the second surface of the first workpiece. Compared with the technical means of pressing the second workpiece against the first surface and the second surface of the first workpiece by a contoured pressing head, the second direction in the embodiment of the present application is inclined relative to the first direction, which is beneficial to increase the magnitude of the force exerted by the second pressing head on the second workpiece, thereby facilitating the second workpiece to fully fit against the second surface of the first workpiece.

[0007] In a possible implementation, the pressure head structure further includes a connecting assembly, and the first driving member drives the second pressure head to slide reciprocatingly in a direction parallel to the second direction through the connecting assembly.

[0008] In this implementation, the first driving member is connected to the second pressing head via a connecting assembly, which facilitates adjustment of the position of the first driving member relative to the second pressing head, thereby facilitating a more compact pressing head structure.

[0104] Reference Figure 7 The embodiment of the present application provides a hot pressing device 4, which includes a machine base 41, a placement table 42 and a pressure head structure 3 in any of the above-mentioned embodiments; the placement table 42 and the first pressure head 31 are both connected to the machine base 41, and the placement table 42 is configured to install the first workpiece 1. Specifically, the placement table 42 is fixedly connected to the machine base 41 through a bracket for clamping the first workpiece 1; four pressure head structures 3 are provided, and the four pressure head structures 3 are respectively arranged at the four corners of the placement table 42, and the pressure head structures 3 are connected to the machine base 41 for synchronously performing hot pressing bonding operations on the four corners of the first workpiece 1, which is conducive to improving the efficiency of hot pressing bonding.

[0105] In the ram structure 3 provided in the embodiment of the present application, after the first ram 31 presses the third surface 21 of the second workpiece 2 onto the first surface 11 of the first workpiece 1 along the first direction B, the second ram 32 is driven to move along the second direction C by the first driving member 33, so as to press the fourth surface 22 of the second workpiece 2 onto the second surface 12 of the first workpiece 1. Compared with the technical means of pressing the second workpiece 2 onto the first surface 11 and the second surface 12 of the first workpiece 1 by a contoured ram, the second direction C in the present application is relatively inclined to the first direction B, which is conducive to increasing the magnitude of the force exerted by the second ram 32 on the second workpiece 2, thereby facilitating the second workpiece 2 to be fully fitted onto the second surface 12 of the first workpiece 1.

[0106] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the disclosure scope of the present application.
