Description

Technical Field

[0001] The present application relates to the field of infrared semiconductor packaging technology, and in particular to a packaging pre-soldering jig. Background Art

[0002] At present, the performance requirements of infrared sensor chips are getting higher and higher, and each sensor chip is becoming more and more miniaturized and refined. The operating environment and machine requirements for the products of infrared sensor chips are also becoming more and more stringent. The existing sealing operation requires first placing the cover plate with a solder ring directly above the tube shell, and then clamping the tube shell and the cover plate with a clamp, and putting them into a vacuum sealing furnace for sealing. The existing manual placement of the cover plate with a solder ring directly above the tube shell requires the operator to visually align the position of the cover plate, which is not accurate enough, and the cover plate is easy to move during the clamping process, thereby offsetting (not directly above the tube shell), and the speed is slow and the efficiency is low.

In the description of the embodiment of the present application, it should be understood that the terms "first", "second" and "third" etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second" and "third" etc. may include one or more of the features explicitly or implicitly. Moreover, the terms "first", "second" and "third" etc. are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiment of the present application described here can be implemented in an order other than illustrated or described here. In addition, the terms "including" and "for" and any of their variations are intended to cover non-exclusive inclusions.

[0026] like Figure 1-2 As shown, this embodiment provides a packaging pre-welding fixture, including a main body 1, the main body 1 is integrally formed, and a tube shell mounting portion 2, a cover plate mounting groove 3 and a clamping groove 4 are arranged on the main body 1. The tube shell mounting portion 2 is used to install the tube shell 5 to be sealed and welded, the cover plate mounting groove 3 is used to install the cover plate 6 to be sealed and welded, and the clamping groove 4 is used to allow a clamping device to pass through and clamp the tube shell mounting portion 2 and the cover plate mounting groove 3.

[0027] like Figure 2 As shown, the tube shell mounting portion 2 is provided with a first mounting surface 21, and the first mounting surface 21 contacts one of the surfaces of the tube shell 5. At least two protrusions 22 are arranged around the first mounting surface 21 along the first direction. In this embodiment, the first mounting surface 21 is square, and two protrusions 22 are arranged on each side of the square first mounting surface 21. The tube shell mounting portion 2 with the ability to accommodate the tube shell 5 is formed between the eight protrusions 22 arranged along the first direction and the first mounting surface 21. The size of the space formed between the protrusions 22 distributed around is close to the size of the tube shell 5, and a gap is arranged between each of the protrusions 22, so that the tube shell 5 is easier to remove. In other embodiments of the present application, the tube shell mounting portion 2 is circular, a circular first mounting surface 21 is provided in the circular tube shell mounting portion 2, at least three protrusions 22 are provided on the circular first mounting surface 21 along a first direction, and a portion for accommodating a circular tube shell 5 is formed between the three protrusions 22 and the circular first mounting surface 21, which is adapted to the circular tube shell 5, and the contact portion between the protrusion and the circular tube shell 5 is set to an arc shape, thereby ensuring the stability of the installation.

[0028] like Figure 3As shown, a second mounting surface 31 is provided on the first mounting surface 21 along the first direction toward the direction close to the main body 1, and the second mounting surface 31 is recessed into the main body 1. The second mounting surface 31 recessed into the main body 1 is configured to contact the cover plate 6. In this embodiment, the second mounting surface 31 is an annular mounting surface, and rounded corners 32 are provided around the second mounting surface 31. When the cover plate 6 is fittedly mounted on the second mounting surface 31, the rounded corners 32 provide a larger adaptation space, and also avoid the problem of difficulty in removal caused by over-tight installation of the cover plate 6 and the second mounting surface 31.

[0029] like Figure 4 As shown, a through clamping groove 4 is provided on the main body 1, and the length direction of the clamping groove 4 is provided along a second direction intersecting with the first direction. The clamping groove 4 divides the tube shell mounting portion 2 and the cover plate mounting groove 3 into two parts respectively. The width of the clamping groove 4 is provided to accommodate the passage of a clamping device, which may be tweezers, clamping arms, etc. An end of the clamping groove 4 away from the tube shell mounting portion 2 is provided as an arc-shaped end, so that it is easier for tweezers or clamping arms to pass through. When the tube shell 5 and the cover plate 6 are respectively installed on the tube shell mounting portion 2 and the cover plate mounting groove 3, due to the positioning effect of the tube shell mounting portion 2 and the cover plate mounting groove 3, the relative positions of the tube shell and the cover plate are positioned. After the positioning is completed, the tube shell 5 and the cover plate 6 are clamped at the same time by a clamping device, such as tweezers, clamping arms, etc., and then placed in a sealing welding device for sealing welding, thereby ensuring the positioning accuracy. Both ends of the clamping groove 4 are respectively provided with chamfers 41 , which provide an open guide during the clamping process of the clamping device, thereby facilitating the clamping of the clamping device.

[0030] The use process of this embodiment is as follows: first, place the cover plate 6 in the cover plate mounting groove 3, at this time, the cover plate 6 has been adhered with a solder sheet, and then place the tube shell 5 in the tube shell mounting portion 2. Since the positions of the tube shell mounting portion 2 and the cover plate mounting groove 3 have been fixed, the positions of the placed cover plate 6 and the tube shell 5 have also reached the preset positions. At this time, the operator holds a clamping device, such as tweezers, pliers and other clamping devices, and passes one of the clamping arms of the clamping device through the clamping groove 4. Then the two clamping arms of the clamping device clamp the cover plate 6 and the tube shell 5 respectively, and send them to the sealing furnace for packaging and welding. When the clamping device clamps the tube shell 5 and the cover plate 6, the tube shell 5 and the cover plate 6 cannot move, so that the cover plate 6 is directly above the tube shell without deviation. The whole process is efficient, the positioning is accurate, and the yield rate of the packaged products is high.

[0031] The above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable people familiar with this technology to understand the content of the present application and implement it accordingly, and they cannot be used to limit the scope of protection of the present application.
