DETAILED DESCRIPTION

[0018] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0019] Please see attached Figure 1-2 As shown, a tinning test device comprises a mounting frame 5, a flux box 1 arranged beside 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. A workpiece 16 is fixed on the clamping assembly, and the workpiece 16 is driven to dip in flux and tin liquid in turn by the driving mechanism 1 3 and the driving mechanism 2 4.

[0020] Please see attached Figure 2 As shown, the clamping assembly includes a mounting plate 6 and a clamp plate 1 7 and a clamp plate 2 8 detachably connected to the bottom of the mounting plate 6, the clamp plate 1 7 and the clamp plate 2 8 are vertically arranged to the bottom of the mounting plate 6, a plurality of through holes 9 are arranged on the clamp plate 1 7, a chuck 10 is passed through the through hole 9, and a pressure block 11 is fixed to one end of the chuck 10 near the clamp plate 2 8, a spring 12 sleeved on the chuck 10 is arranged between the pressure block 11 and the clamp plate 1 7, and the workpiece 16 is abutted against the clamp plate 2 8 by the spring 12 and the pressure block 11, wherein, preferably, two chucks 10 can be connected to one pressure block 11 as a group, or one chuck 10 can be connected to one pressure block 11 individually, and the specific arrangement is based on the experimental needs. Specifically, the chuck 10 is pulled toward one side of the clamp 1 7 so that the pressure block 11 compresses the spring 12, and then the workpiece 16 to be tinned is placed between the clamp 2 8 and the pressure block 11, and placed close to the surface of the clamp 2 8, and then the chuck 10 is released. The pressure block 11 clamps the workpiece 16 firmly between the clamp 2 8 and the pressure block 11 under the action of the rebound force of the spring 12. The clamp 1 7 and the clamp 2 8 can adapt to workpieces 16 of different thicknesses, and multiple chucks 10 can clamp multiple workpieces 16 at the same time. The structure is simple and the operation is convenient, which greatly improves the detection efficiency; the cost of the test device is saved, and multiple chucks 10 can also clamp a workpiece 16 together. The specific situation is adjusted according to the type and size of the workpiece 16, and the application range is wide.

[0021] The driving mechanism 13 includes a motor 131 fixed on the mounting frame 5, a screw rod 132 driven by the motor 131, and a slider 1 connected to the screw rod 132 (not shown in the accompanying drawings). The driving mechanism 24 is fixed on the slider 1, and the driving mechanism 24 includes a motor 241, a screw rod 242 driven by the motor 241, and a slider 2 connected to the screw rod 242 (not shown in the accompanying drawings). Specifically, because the tinning test of the workpiece 16 only tinns a part of the workpiece 16, not all of the workpiece 16, the descending height and descent speed of the workpiece 16 must be controlled during the tinning. In order to facilitate observation by the staff, the driving mechanism 13 and the driving mechanism 24 in this embodiment both use a screw as a transmission component. 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 16 to descend too fast, it is easy to cause slight fluctuations on the surface of the tin liquid and thus affect the accuracy of the tinning of the workpiece 16.

[0022] The mounting plate 6 is L-shaped, and includes a fixing portion 61 and a clamping portion 62 fixedly connected to the slider 2. The splint 1 7 and the splint 2 8 are detachably mounted on the lower surfaces of the splint 1 7 and the splint 2 8; specifically, the lower surface of the clamping portion 62 is provided with a groove 621 arranged along the length direction, and one side edge of the splint 1 7 and the splint 2 8 is clamped in the groove 621 and fixed by screws. When the splint 1 7, the splint 2 8 or the chuck 10 is damaged, the splint 1 7 and the splint 2 8 can be disassembled and replaced at any time, and the operation is simple.

[0023] In the above embodiment, preferably, the clamping portion 62 is provided with a clearance groove 622 in the middle for placing the workpiece 16. Figure 2 As shown, in this embodiment, a larger workpiece 16 is clamped, and the upper end of the workpiece 16 needs to pass through the clearance groove 622 for clamping and fixing. If the workpiece 16 is smaller, it is directly clamped under the clamping portion 62 and does not need to pass through the clearance groove 622. It can be seen that this device can be used for workpieces 16 of various types and sizes and has a wide range of applications.

[0024] In the above embodiment, since the workpiece 16 itself is relatively thin, if a larger workpiece 16 is clamped, in order to prevent the unclamped portion above the workpiece 16 from being deformed and to improve the stability of the workpiece 16, a plurality of clamping auxiliary members 13 are provided on the fixing portion 61 and are arranged above the clamping portion 62. The clamping auxiliary members 13 include a fixed Kun shaft 131 and a movable Kun shaft 132. The fixed Kun shaft 131 and the clamping plate 28 are located on the same vertical plane. The fixing portion 61 is provided with a movable groove 133. One end of the movable Kun shaft 132 passes through the movable groove 133 and is connected to a movable The movable nut (not shown in the accompanying drawings) is used, and the movable Kun shaft 132 can slide left and right in the movable groove 133; specifically, first pull the chuck 10 to make the pressure block 11 compress the spring 12, then pass the bottom of the workpiece 16 from top to bottom through the make way groove 622 and place it between the second clamping plate 8 and the pressure block 11, then gently release the chuck 10 to make the pressure block 11 clamp the bottom of the workpiece 16 between the second clamping plate 8 and the pressure block 11, then move the movable Kun shaft 132 toward the direction of the fixed Kun shaft 131 to clamp the top of the workpiece 16, and then tighten the movable Kun shaft 132 through the movable nut.

[0025] The device can clamp multiple workpieces 16 at the same time. In order to improve the accuracy of tinning multiple workpieces 16, the bottom ends of the workpieces 16 need to be at the same horizontal height. Therefore, a reference table 14 is also provided on one side of the flux box 1. The reference table 14 is placed under the clamping component. In the above process, the clamping component needs to be moved to the top of the reference table 14 through the driving mechanism 3. Then, when placing the workpiece 16, the bottom of the workpiece 16 needs to contact the reference table 14. Then, the workpiece 16 is clamped by the chuck 10, thereby ensuring that the parts to be tinned of multiple workpieces 16 in the same batch are at the same height, thereby improving the accuracy of tinning.

[0026] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. 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.

[0027] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
