Therefore, there is a need to invent a practical device for collecting foreign matter after soldering. Utility Model Content

[0004] The purpose of this utility model is to provide a device for holding foreign objects after soldering, so as to solve the problem mentioned in the background art that foreign objects and solder balls fall onto the workbench during the soldering process between the motor PCBA drive board and the U, V, W three-phase starting lines, causing damage to the workbench, low work efficiency, and inconvenience in operation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a device for holding foreign objects after soldering, including a holding component. The holding component includes a support frame, a drawer, a storage slot, and a mesh plate. The support frame has an insertion port on one side and the top of the support frame is open. The drawer is inserted into the support frame through the insertion port. The storage slot is opened inside the top of the drawer. The mesh plate is fixed to the top of the support frame.

[0007] Furthermore, a handle is fixedly connected to the outer end of the drawer.

[0008] Furthermore, the device also includes a leveling assembly, which includes a push plate and a lever. The push plate is located inside the support frame and above the drawer. The support frame has a sliding hole on one side in the direction of drawer insertion. The sliding hole extends along the direction in which the drawer is inserted into the support frame. The lever is slidably disposed in the sliding hole. One end of the push plate is located in the sliding hole and connected to the lever.

[0009] Furthermore, the support frame is provided with a guide groove on the other side of the drawer insertion direction, extending along the direction in which the drawer is inserted into the support frame, and the end of the push plate away from the lever is located in the guide groove.

[0010] Furthermore, the sliding hole includes a groove located on the outside of the support frame, a slot located on the inside of the support frame, and a docking hole connecting the groove and the slot.

[0014] Compared to existing technologies, the advantages of the device for containing foreign objects after soldering according to the embodiments of this application are:

[0015] 1. By setting up a holding component, when in use, the drive board is placed on the stencil. When soldering the drive board, foreign objects and solder balls generated by soldering fall through the holes of the stencil and are collected in the storage slot on the drawer. This prevents foreign objects and solder balls from falling onto the desktop and causing damage. It also makes it easier for staff to perform soldering operations on the drive board and improves work efficiency.

[0016] Second, based on the first beneficial effect, by setting up a leveling component, when solder balls fall into the storage tank, the solder balls tend to accumulate in a certain place in the storage tank. When too much accumulates, the pusher is pushed, causing the pusher to move. During the movement, the pusher flattens the accumulated solder balls, thereby maximizing the utilization of the internal space of the storage tank. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figures 1-2 As shown, this embodiment is a device for holding foreign objects after soldering. The device includes a holding component, which includes a support frame 11, a drawer 12, a storage slot 13, and a mesh plate 14. The support frame 11 has an insertion port 15 on one side and the top of the support frame 11 is open. The drawer 12 is inserted into the support frame 11 through the insertion port 15. The storage slot 13 is opened inside the top of the drawer 12. The mesh plate 14 is fixed to the top of the support frame 11.

[0029] The support frame 11 serves as the mounting carrier for the drawer 12 and the stencil 14. The stencil 14 is located above the drawer 12 and is used to hold the drive board to be soldered, as well as to allow foreign objects and solder balls generated during soldering to fall through the holes in the stencil 14 into the storage slot 13 below. The storage slot 13 on the drawer 12 is used to collect foreign objects and solder balls generated during soldering. During use, the drawer 12 needs to be periodically removed to clean the foreign objects and solder balls in the storage slot 13.

[0030] A handle 16 is fixedly connected to the outer end of the drawer 12, which facilitates pushing and pulling the drawer 12. Specifically, the handle 16 is used to move the drawer 12 outward. By holding the handle 16 and pulling the drawer 12 outward, the drawer 12 is moved to the outside, which facilitates the handling of foreign objects and solder balls in the storage slot 13.

[0031] Working principle: When in use, the drive board is placed on the mesh plate 14, and the drive board can be soldered. When soldering the drive board, foreign objects and solder balls generated by soldering fall into the storage slot 13 on the drawer 12 through the holes of the mesh plate 14. When the storage slot 13 is full of foreign objects or solder balls, hold the handle 16 and pull the drawer 12 outward, so that the drawer 12 and the storage slot 13 move to the outside, thereby facilitating the handling of foreign objects and solder balls in the storage slot 13.

[0032] The above steps, through the cooperation between the support frame 11, the mesh plate 14 and the collection tank 13, enable the collection tank 13 to collect foreign objects and solder balls.

[0033] Please see Figures 2-5 As shown, this embodiment, based on the above embodiment, further includes a flattening component. The flattening component includes a push plate 23 and a lever 26. The push plate 23 is located inside the support frame 11 and positioned above the drawer 12. The support frame 11 has a sliding hole on one side in the direction of drawer 12 insertion, extending along the direction of drawer 12 insertion into the support frame 11. The lever 26 is slidably disposed within the sliding hole, and one end of the push plate 23 is located within the sliding hole and connected to the lever 26. By sliding the lever 26, the push plate 23 can be moved above the drawer 12. During the movement, the push plate 23 can flatten excessively piled solder balls, thereby maximizing the utilization of the internal space of the storage slot 13.

[0034] The support frame 11 has a guide groove 29 on the other side of the drawer 12 insertion direction, extending along the direction in which the drawer 12 inserts into the support frame 11. The end of the push plate 23 away from the lever 26 is located in the guide groove 29. By setting the guide groove 29, the stability of the push plate 23 during movement is improved.

[0035] Specifically, the sliding hole includes a groove 21 located on the outside of the support frame 11, a slot 22 located on the inside of the support frame 11, and a mating hole 24 connecting the groove 21 and the slot 22. One end of the push plate 23 is slidably disposed in the slot 22, and the toggle block 26 is slidably disposed in the groove 21. The push plate 23 and the toggle block 26 are connected by a plug-in plate 25 passing through the mating hole 24. The width of the groove 21 and the width of the slot 22 are both greater than the width of the mating hole 24. One end of the plug-in plate 25 is fixedly connected to the inner end of the toggle block 26, and the other end of the plug-in plate 25 is inserted into the push plate 23.

[0036] The groove 21 is used for connecting and moving the push block 26, and the slot 22 is used for connecting and moving the push plate 23. The push plate 23 flattens the solder balls accumulated in the receiving slot 13, and the push block 26 is used to drive the push plate 23 to move together. The mating hole 24 is used for communication between the slot 22 and the groove 21, and the plug-in plate 25 is used for connecting the push block 26 and the push plate 23. Pushing the push block 26 causes the push block 26 to move together with the push plate 23 through the plug-in plate 25.

[0037] The push plate 23 has a slot 28 at the insertion point of the plug-in plate 25 for the plug-in plate 25 to be inserted into. A push-pull plate 27 is fixedly connected to the center of the outer end of the lever 26. The slot 28 is used for the connection between the plug-in plate 25 and the two ends of the push plate 23. The push-pull plate 27 is used to drive the lever 26 to move. By squeezing the push-pull plate 27 and pushing it, the push-pull plate 27 drives the lever 26 to move in the groove 21. The lever 26 drives the push plate 23 to move in the support frame 11 through the plug-in plate 25.

[0038] Working principle: When the push-flattening component is not in use, the push plate 23 is located at one end inside the support frame 11. When the push-flattening component is in use, push the push-pull plate 27 by hand, so that the push-pull plate 27 drives the lever 26 to move in the groove 21, causing the lever 26 to drive the plug plate 25 to move in the mating hole 24. At the same time, the lever 26 drives the push plate 23 to move along the direction of the slot 22 through the plug plate 25, so that the push plate 23 flattens the accumulated solder balls during the movement. When the push plate 23 is to be replaced, push the push-pull plate 27, so that the push-pull plate 27 drives the push plate 23 to the opening of the support frame 11 through the plug plate 25 and the lever 26. Pull the lever 26 outward by hand, so that the lever 26 drives the plug plate 25 to separate from the plug slot 28. Then take the push plate 23 by hand, so that the push plate 23 separates from the slot 22, thereby facilitating the replacement of the push plate 23.

[0039] The above steps can improve its functionality.
