Abstract
Description
Technical Field
[0001] The utility model relates to the field of semiconductor packaging, and particularly to a strip plug structure with high friction force. Background Art
[0002] In the semiconductor packaging process, after the processes of cutting leads and bending, multiple circuit units originally connected by a lead frame are cut off and separated into independent individuals. To facilitate batch transportation and processing in subsequent processes, when the equipment unloads materials, the circuits are loaded into a turnover strip according to a specified quantity, and then the turnover strip is used for loading and unloading materials in each process. The turnover strip needs to be reused and replaced after reaching a specified time. Some equipment uses gravity to transfer circuits, and when unloading materials, the circuits slide along an inclined track into the strip, directly or indirectly impacting the plug at the bottom of the strip. In the design of conventional plugs, when the weight of the circuit is small, there will be no problem within the replacement cycle, but when the weight of the circuit is large, the impact caused by its falling is greater. After multiple rounds of impact, the plug will gradually become loose and fall off, and finally the entire tube of circuits will spill onto the ground, resulting in defective products and losses. Summary of the Invention
[0003] The utility model provides a strip plug structure with high friction force, which changes the shape of the plug at the bottom of the turnover strip to increase the friction force with the inner wall of the strip, thereby solving the technical problem that the traditional plug is prone to falling off within the replacement cycle of the turnover strip mentioned in the background art.
[0004] The technical solution of the utility model is as follows: A strip plug structure with high friction force, comprising: a plug main body, a hollow groove, a plug piece structure, and a handle structure. The hollow groove is arranged at the center of the plug main body. The plug piece structure is arranged on both the upper and lower sides of the plug main body. The handle structure is arranged at one of the left and right ends of the plug main body, and the handle structure is perpendicular to the plug main body. The plug main body, the plug piece structure, and the handle structure all have elasticity, and the hollow groove is arranged along the length direction of the plug main body.
[0005] Further, the hollow groove is in a rhombus shape, and the two inner angles in the long diagonal direction of the hollow groove are not equal, while the two inner angles in the short diagonal direction are equal.
[0006] Further, the inner angle in the long diagonal direction of the hollow groove close to the handle structure is greater than the inner angle away from the handle structure.
[0007] Further, the inner angle in the long diagonal direction of the hollow groove close to the handle structure is 25° - 35°, and the inner angle away from the handle structure is 5° - 15°.
[0008] Further, the inner angle in the long diagonal direction of the hollow groove close to the handle structure is 32°, and the inner angle away from the handle structure is 11°.
[0009] Furthermore, the plug structure is a fin-shaped piece inclined toward the handle structure, and the number of fins on the upper and lower sides is equal and evenly distributed.
[0010] Furthermore, the width of the plug body is 50% of the distance between the inner walls of the material strip, and the length of the plug sheet structure is 50% of the distance between the inner walls of the material strip.
[0011] Furthermore, a lip protrusion is provided at the bottom end of the handle structure close to the plug body.
[0012] Beneficial effects of the utility model: a hollow groove is added inside the plug, which is made of rubber and is in an open state before being inserted, and the overall thickness is slightly higher than the material strip; after the material strip is inserted, the hollow groove is compressed and closed, generating a large elastic force perpendicular to the inner wall of the material strip, and increasing the friction by increasing the contact surface pressure. The shape of the hollow groove is a diamond with a small angle at the front and a large angle at the back. This structure has a certain guiding effect, so that the plug can be deformed in the desired direction when the material strip is inserted, which is convenient for insertion. A protrusion is added to the end of the plug handle to increase friction, which is more convenient when the plug needs to be pulled out, and can further improve the impact resistance after it is fully inserted.

[0016] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0017] In an embodiment of the present utility model, Figure 1 and Figure 2 It is a structural schematic diagram provided according to the specific structure of a high friction material strip plug structure of the utility model, such as Figure 1 and Figure 2 As shown, the utility model specifically includes:
[0018] A plug head main body 1, a hollow groove 2, a plug piece structure 3 and a handle structure 4. The hollow groove 2 is arranged at the center of the plug head main body 1. The plug piece structure 3 is arranged on the upper and lower sides of the plug head main body 1. The handle structure 4 is arranged at one of the left and right ends of the plug head main body 1. The handle structure 4 is perpendicular to the plug head main body 1. The plug head main body 1, the plug piece structure 3 and the handle structure 4 are all elastic. The hollow groove 2 is arranged along the length direction of the plug head main body 1.
[0019] In an embodiment of the present invention, the hollow groove 2 is diamond-shaped, and the two inner angles in the long diagonal direction of the hollow groove are not equal, while the two inner angles in the short diagonal direction are equal.
[0020] In an embodiment of the present invention, the inner angle of the hollow groove 2 in the long diagonal direction close to the handle structure 4 is greater than the inner angle away from the handle structure 4.
[0021] In an embodiment of the present invention, the inner angle of the hollow groove 2 in the long diagonal direction close to the handle structure 4 is 25 - 35°, and the inner angle away from the handle structure 4 is 5 - 15°.
[0022] In an embodiment of the present invention, the inner angle of the hollow groove 2 in the long diagonal direction close to the handle structure 4 is 32°, and the inner angle away from the handle structure 4 is 11°.
[0023] In an embodiment of the present invention, the plug piece structure 3 is a wing-shaped piece inclined towards the handle structure 4, and the number of the wing-shaped pieces on the upper and lower sides is equal and evenly distributed.
[0024] In an embodiment of the present invention, the width of the plug head main body 1 is 50% of the inner wall spacing of the strip, and the length of the plug piece structure 3 is 50% of the inner wall spacing of the strip.
[0025] In an embodiment of the present invention, a lip pattern protrusion 41 is arranged at the bottom end of the handle structure 4 on the side close to the plug head main body 1.
[0026] As Figure 1 shown, when the plug head is not inserted into the strip, the plug head is in an expanded state. The distance between the two wing-shaped pieces on the side away from the handle structure is 1.5 times the inner wall spacing of the strip, which is the narrowest part. The distance between the two wing-shaped pieces on the side close to the handle structure is 1.75 times the inner wall spacing of the strip, which is the widest part.
[0027] The widths of the front and rear ends of the plug head main body 1 are equal, approximately 50% of the inner wall spacing of the strip. The middle is divided into upper and lower symmetric sides by the hollow groove 2, each accounting for half of the width. Since the length of the main body 1 increases after the hollow groove 2 is closed, the initial length of the plug head main body 1 needs to be shortened by about 5 - 10% compared with the existing design.
[0028] The hollow groove 2 is located in the center of the main body 1 and is diamond-shaped when not under compression. The long diagonal is about 72% of the length of the main body 1, and the short diagonal is approximately the width of the main body plug of the main body 1. Considering the operability when inserting the plug into the strip, generally the front end angle is taken as 5~15°, and the rear end angle is taken as 25~35°. In this example, the front and rear end angles are 11° and 32° respectively.
[0029] The plug piece structures 3 are evenly distributed on both sides of the main body 1. To provide sufficient contact area and smooth insertion, in this example, the protruding height of the plug piece structures on both sides is 50% of the inner wall spacing of the strip, and the backward inclination angles are about 40° and 75°. Increasing the number of wing-shaped pieces can provide more friction, but the wing thickness needs to be reduced to avoid interference with each other during deformation.
[0030] The handle structure 4 is located at the tail of the main body of the plug. Its length is greater than the inner wall spacing of the strip. There are lip-like protrusions 41 at the end, making it easier to grasp the handle part 4 when the plug needs to be pulled out. As a plug at the bottom of the turnover strip, generally, the plug is fully inserted into the strip. At this time, the handle structure 4 can additionally enhance the friction force after deformation.
[0031] The materials of the main body 1 of the plug, the plug piece structure 3, and the handle structure 4 are selected as rubber, which has a certain elastic deformation ability. When inserting into the strip, since the wing-shaped pieces are in a backward bent shape, it is easier to insert in the forward direction. At the same time, the first entering wing-shaped pieces drive the hollow groove 2 to close, facilitating the subsequent wing-shaped pieces to enter the strip in turn.
[0032] As Figure 3 shown, after the plug is inserted into the strip, the wing-shaped pieces deform to form a contact surface with the inner wall of the strip, generating a certain friction force. At the same time, the hollow groove 2 of the main body of the plug closes towards the center, causing the main body of the plug on the upper and lower sides of the hollow groove to generate an elastic force perpendicular to the inner wall of the strip, enhancing the pressure of the wing-shaped pieces on the inner wall of the strip and further increasing the friction force. In addition, the handle structure 4 of the plug fully inserted into the strip can also provide a certain support. Therefore, the plug of this design can withstand a greater impact force.
[0033] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
