Description

Technical Field

[0001] The utility model relates to the technical field of tinning, in particular to a tinning test device with adjustable angle. Background Art

[0002] Semiconductors and other electronic packaging components require regular tinning tests to ensure their solderability. In existing equipment, due to structural flaws in the components used to hold the tester, the tinning mechanism typically tests each component individually, resulting in low efficiency and significant hindrance to the tinning process. Furthermore, the tinning mechanism's fixed angle cannot be adjusted, making it difficult to ensure the tinned portion of the workpiece is aligned with the tinning pot, particularly for irregularly shaped workpieces. This, in turn, affects the accuracy of the workpiece test. Utility Model Content

DETAILED DESCRIPTION

[0013] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0014] Please see the attached Figure 1-2 As shown, an angle-adjustable tinning test device includes a mounting frame 5, a flux box 1 arranged next to the mounting frame 5, and a tinning pot 2. The mounting frame 5 is provided with a clamping assembly, a driving mechanism 1 3 for driving the clamping assembly to move left and right, and a driving mechanism 2 4 for driving the clamping assembly to move up and down. The workpiece is fixed to the clamping assembly, and the driving mechanism 1 3 and the driving mechanism 2 4 drive the workpiece to sequentially dip into the flux and tin liquid.

[0015] The clamping assembly includes a mounting plate 6, a rotating bracket 7 and a plurality of clips 8 fixed to the rotating bracket 7. The mounting plate 6 is provided with a mounting hole 61. One end of the rotating bracket 7 is provided with a mounting head 71 that cooperates with the mounting hole 61. A threaded hole 1 (not shown in the accompanying drawings) is provided in the mounting head 71. The mounting head 71 of the rotating bracket 7 is placed in the mounting hole 61 and is vertically fixed to the mounting plate 6 by a bolt (not shown in the accompanying drawings) placed behind the mounting plate 6. When the clamping angle needs to be adjusted, the bolt is loosened, and the rotating bracket 7 is rotated to the tinning angle required for the test according to the shape of the workpiece. When the part of the workpiece to be tinned is facing downward, the nut is tightened to fix the rotating bracket 7 to ensure that the workpiece can effectively undergo tinning test and improve the test accuracy of the workpiece.

[0016] The rotating bracket 7 is provided with a fixing groove 72 which runs through the upper and lower parts, and the fixing groove 72 is arranged along the length direction of the rotating bracket 7. One of the hand-held parts of the clamp 8 is provided with a threaded hole three 81 corresponding to the fixing groove 72. The side of the rotating bracket 7 is also provided with a plurality of threaded holes two 73 which are connected with the fixing groove 72. The hand-held part of the clamp 8 with the threaded hole three 81 is placed in the fixing groove 72 and the threaded hole two 73 is aligned with the threaded hole two 73. Then, the clamp 8 is fixed to the rotating bracket 7 by screws passing through the threaded hole two 73 and the threaded hole three 81 in sequence. The rotating bracket 7 can clamp multiple workpieces side by side at a time. It has a simple structure and is easy to operate, which greatly improves the detection efficiency.

[0017] The driving mechanism 1 3 includes a motor 1 31 fixed on the mounting frame 5, a screw 1 32 driven by the motor 1 31, and a slider 1 connected to the screw 1 32 (not shown in the accompanying drawings). The driving mechanism 2 4 is fixed on the slider 1. The driving mechanism 2 4 includes a motor 2 41, a screw 2 42 driven by the motor 2 41, and a slider 2 connected to the screw 2 42 (not shown in the accompanying drawings). Specifically, because the workpiece tinning test only tins a part of the workpiece, not the entire workpiece 16, the workpiece's lowering height and lowering speed must be controlled during tinning. In order to facilitate observation by staff, the driving mechanism 1 3 and the driving mechanism 2 4 in this embodiment both use screws as transmission components. The screw transmission speed is slow and controllable, and the tinning accuracy is high. If a linear module is used, it is not conducive to the staff to observe whether the tinning is in place. Secondly, if the linear module drives the workpiece to descend too fast, it is easy to cause slight fluctuations on the surface of the tin liquid, thereby affecting the accuracy of the workpiece tinning.

[0018] This device can clamp multiple workpieces at the same time. In order to improve the accuracy of tinning multiple workpieces, the bottom ends of the workpieces need to be at the same horizontal height. Therefore, a reference platform 9 is also provided on one side of the flux box 1. The reference platform 9 is placed under the clamping component. In the above process, the clamping component needs to be moved to the top of the reference platform 9 through the driving mechanism 3. Then, when clamping the workpiece with the clamp, it is necessary to ensure that the bottom of each workpiece contacts the reference platform 9, thereby ensuring that the parts to be tinned of multiple workpieces in the same batch are at the same height, thereby improving the accuracy of tinning.

[0019] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0020] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
