Description

Technical Field

[0001] This utility model relates to a material box, specifically a reverse-release material box with a material-locking structure. Background Technology

[0002] In the semiconductor packaging process, the cassette is a very important tool used to hold semiconductor chips or wafers. These chips and wafers need to be properly handled and stored during the packaging process, and the cassette plays this role. It can ensure that the chips are not bumped or damaged during transportation, and at the same time facilitate loading and unloading operations between different processes, ensuring that the entire packaging process can proceed smoothly.

[0003] While the use of cassettes in semiconductor packaging facilitates material transportation and storage, it also presents several challenges. For instance, if an operator accidentally places a cassette upside down, the material may be blocked by the internal structure, preventing it from smoothly entering the equipment for loading. Furthermore, if the equipment resonates when the material is pushed into the cassette after processing, the material may re-emerge from the cassette, interfering with the processing platform or the next material and causing jamming during unloading. These issues not only affect production efficiency but may also lead to material damage or equipment malfunction, requiring extra caution during actual operation. Utility Model Content

[0004] The purpose of this utility model is to provide a backflow prevention box with a material-locking structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A reverse-release material box with a material-locking structure includes a material box body, a material inlet at one end of the material box body, and a plurality of insertion slots equidistantly and symmetrically arranged on both sides of the inner wall of the material box body, wherein a material tray is inserted and placed in the insertion slots.

[0007] A material clamping structure is provided at the feed inlet of the insertion slot. The material clamping structure includes a locking member that can move and make way relative to the feeding direction of the insertion slot when the material tray is inserted, and an elastic member connecting the locking member and the main body of the material box. The locking member has a pressing part on the side away from the feeding direction of the insertion slot for being triggered to make way.

[0008] As described above, a material-blocking anti-reverse material box with a material-locking structure includes a locking block, which is rotatably mounted at the feed inlet of the insertion slot via a rotating pin. The fan-shaped surface of the locking block on the side away from the feed direction of the insertion slot forms the extrusion section.

[0009] As described above, a reverse-release material box with a material-locking structure includes an elastic element comprising an abutment pin slidably inserted into the main body of the material box and a first spring sleeved on the abutment pin. One end of the first spring near the locking block is fixed to the abutment pin, and the other end abuts against the main body of the material box.

[0010] As described above, a material-blocking box with a material-locking structure is provided: the locking member includes a blocking post located at the feed inlet of the insertion slot, one end of the blocking post is inserted into an embedded cavity formed in the main body of the box and connected to an elastic member placed in the embedded cavity, and the other end of the blocking post has a rounded corner on the side away from the feed direction of the insertion slot to form the extrusion part.

[0011] As described above, an anti-reverse material box with a material-locking structure includes an elastic element comprising a plug rod that is slidably inserted into the main body of the material box, one end of which forms a convex plate and the convex plate is fixed to the blocking post;

[0012] A second spring is fitted on the plug rod. One end of the second spring abuts against the convex plate, and the other end abuts against the inner wall of the embedded cavity.

[0013] As described above, a reverse-discharge tray with a material-holding structure includes a material-holding frame for holding multiple semiconductor chips. The material-holding frame is provided with a material-holding positioning hole and a second indicator arrow at its front and rear ends along the feeding direction.

[0014] As described above, a backflow prevention box with a material-locking structure has an arc-shaped slope on one side of the insertion slot in the direction of the inlet, which is used to guide the material placement frame to be smoothly inserted into the insertion slot.

[0015] As described above, a reverse-displacement material box with a material-locking structure is provided with a first indicator arrow on the top of the main body of the material box. The first indicator arrow cooperates with a second indicator arrow to indicate the correct insertion direction of the material placement frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When the tray is fully inserted into the main body of the material box along the feeding direction, the clamping structure will abut against the side of the tray located at the feed inlet, thereby restricting the tray from retracting within the main body of the material box. The ingenuity of this structure lies in its ability to effectively prevent the tray from retracting due to equipment resonance during processing. By setting up the clamping structure, the tray is firmly fixed inside the material box, and even if the equipment resonates, the tray will not shift. This design not only improves the stability of the production process but also reduces the equipment downtime and the risk of material damage caused by jamming, thereby improving overall production efficiency and equipment reliability.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1-5 In this embodiment of the utility model, an anti-reverse feeding box with a material-clamping structure includes a box body 1, a feeding port opened at one end of the box body 1, and a plurality of insertion slots 2 equidistantly and symmetrically opened on both sides of the inner wall of the box body 1. A material tray is inserted into the insertion slot 2; a material-clamping structure is provided at the feeding port of the insertion slot 2.

[0030] In this embodiment, material placement is a crucial step in the semiconductor packaging process. First, the material is placed on a dedicated tray to ensure it is securely positioned and to prevent any movement or tilting during subsequent operations. Then, the tray is inserted into a slot 2 within the main body 1 of the packaging box. This slot 2 is strategically designed to ensure the tray is firmly positioned within the main body 1 after insertion, forming a complete support structure that guarantees the safe storage and transportation of the material. The precise fit between the tray and the main body 1 not only enhances the stability of the material but also effectively prevents... To prevent damage to materials caused by external vibration or other factors, and to further enhance the stability of the system, a material clamping structure is set on the main body 1 of the material box. After the material tray is fully inserted into the main body 1 of the material box, this structure can automatically align and abut against the side of the material tray located at the inlet. Through this abutment mechanism, the material clamping structure prevents any backflow of the material tray after insertion. Especially during the packaging process, the positional accuracy of the material tray is crucial. Therefore, the material clamping structure is precisely designed to ensure the stability of the material tray after insertion, so that it is not affected by external forces throughout the entire production process and can remain in the predetermined position for a long time.

[0031] The precision and reliability of the entire insertion process greatly improves production efficiency, reduces material waste, and ensures that every link in the production process can operate efficiently as expected. In addition, this design also optimizes the operation process. Operators only need to accurately insert the material tray into the insertion slot 2, and the clamping structure will automatically complete the positioning and fixation without additional manual intervention, thereby greatly improving the automation level and work efficiency of the production line. Through this design, the entire packaging process becomes simpler, safer, and more efficient, reducing the difficulty of operation and also reducing potential risks and operational errors.

[0032] Specifically, the material clamping structure includes a locking member that can move and make way relative to the feeding direction of the insertion slot 2 when the material tray is inserted, and an elastic member connecting the locking member and the material box body 1. The locking member has a pressing part on the side away from the feeding direction of the insertion slot 2 for being triggered to make way.

[0033] When the tray is inserted through the feed port, the front end of the tray comes into contact with and is squeezed by the pressing part of the locking member. After the locking member is subjected to force, it cooperates with the elastic member to elastically move outward, so as to allow the tray to enter the insertion groove 2. After the tray is completely inserted into the insertion groove 2, the locking member elastically resets and locks the end of the tray to prevent the tray from protruding outward.

[0034] Please see Figure 3 , Figure 6 and Figure 9As a further embodiment of the present invention, the tray includes a material placement frame 4 for supporting multiple semiconductor chips 5, and the material placement frame 4 is provided with a feeding positioning hole 6 and a second indicator arrow 7 at its front and rear ends along the feeding direction.

[0035] The insertion slot 2 has an arc-shaped slope 8 on one side in the direction of the feed inlet. The arc-shaped slope 8 is used to guide the material placement frame 4 to be smoothly inserted into the insertion slot 2.

[0036] The top of the material box body 1 is provided with a first indicator arrow 3, which cooperates with the second indicator arrow 7 to indicate the correct insertion direction of the material tray.

[0037] In this embodiment, the material placement frame 4 is designed to support the placement of the semiconductor chip 5 and ensure the stability and safety of the material throughout the packaging process. When the material placement frame 4 is ready to be inserted into the material box body 1, the design details greatly improve the convenience and accuracy of the operation. Specifically, the second indicator arrow 7 on the material placement frame 4 is aligned with the first indicator arrow 3 on the material box body 1, ensuring the correct direction during insertion and effectively preventing the material placement frame 4 from being mistakenly inserted in the opposite direction.

[0038] In addition, an arc-shaped slope 8 is designed below the insertion slot 2 at the feed inlet of the material box body 1. This is designed to improve the ease of insertion of the end of the material placement frame 4. When the material placement frame 4 is about to be inserted into the material box body 1, the arc-shaped slope 8 allows the end of the material placement frame 4 to enter the insertion slot 2 more smoothly, and the insertion action can be completed without too much external force. This design effectively avoids potential problems caused by poor insertion or excessive operating force, such as damage to the material frame or impact on operating efficiency. Through the guiding effect of the arc-shaped slope 8, the insertion process of the material placement frame 4 is not only smoother, but also reduces the complexity of manual operation, further improving the overall use effect.

[0039] Please see Figure 4 and Figure 6 For example, in one embodiment, the locking member includes a locking block 9, which is rotatably mounted at the feed inlet of the insertion slot 2 via a rotating pin 10. The fan-shaped surface 11 of the locking block 9 on the side away from the feed direction of the insertion slot 2 forms the extrusion part.

[0040] The elastic element includes an abutment pin 12 that is slidably inserted into the material box body 1 and a first spring 13 sleeved on the abutment pin 12. One end of the first spring 13 near the locking block 9 is fixed to the abutment pin 12, and the other end abuts against the material box body 1.

[0041] In this embodiment, the fan-shaped surface 11 on one side of the locking block 9 cooperates with the arc-shaped slope 8 formed on the insertion slot 2. The combination of the two improves the smoothness and convenience of the insertion process of the material placement frame 4. Through this design, the material placement frame 4 can be inserted into the material box body 1 more easily, avoiding the resistance caused by improper insertion, thereby ensuring the efficiency of operation.

[0042] The locking block 9 is tightly connected to the material box body 1 via the rotating pin 10. The rotating pin 10 is positioned close to the feed inlet side, ensuring that when the material feeding frame 4 is inserted into the material box body 1, the locking block 9 will rotate due to the contact of the fan-shaped surface 11. During insertion, the end of the material feeding frame 4 contacts one side of the fan-shaped surface 11 of the locking block 9. With the application of external force, the locking block 9 will rotate around the rotating pin 10. Because the rotating pin 10 is close to the feed inlet, the rotation of the locking block 9 will have an eccentric effect. When the locking block 9 rotates, it will drive the contact pin 12 to slide. This action will cause the first spring 13 to be compressed and deformed. The deformation and rebound force of the first spring 13 The locking block 9 is provided with the power to reset. When the material placement frame 4 is fully inserted into the material box body 1, the locking block 9 will automatically return to the initial position under the action of the rebound force of the first spring 13. The vertical surface of the locking block 9 will abut against the edge of the material placement frame 4 near the feed port. At this time, the bottom of the vertical surface of the locking block 9 is in close contact with the receiving platform of the insertion slot 2, forming an effective blocking force to prevent the locking block 9 from rotating towards the feed port. Through this design, the locking block 9 can not only effectively limit the material placement frame 4, but also prevent the material placement frame 4 from retracting inside the material box body 1 due to external interference or improper operation, ensuring the stability and safety of the material in the material box.

[0043] Please see Figure 7 and Figure 8 In another exemplary embodiment, the locking member includes a blocking post 14 located at the feed inlet of the insertion slot 2. One end of the blocking post 14 is inserted into an embedded cavity formed in the material box body 1 and connected to an elastic member placed in the embedded cavity. The other end of the blocking post 14 has a rounded corner 15 on the side away from the feed direction of the insertion slot 2 to form the extrusion part.

[0044] The elastic element includes a plug rod 17 that is slidably inserted into the material box body 1, one end of the plug rod 17 forming a convex disk 16 and the convex disk 16 being fixed to the blocking post 14;

[0045] A second spring 18 is sleeved on the plug rod 17. One end of the second spring 18 abuts against the cam 16, and the other end abuts against the inner wall of the embedded cavity.

[0046] In this embodiment, the cooperation between the rounded corner 15 of the blocking column 14 near the feed inlet and the arc slope 8 ensures that the insertion of the material placement frame 4 into the material box body 1 is both smooth and convenient. When the material placement frame 4 is pushed towards the material box body 1, its end will contact the rounded corner 15, generating a certain resistance force. This resistance force can not only smoothly guide the blocking column 14 to move upward, but also ensure the stability of the frame during the insertion process. As the resistance force is applied, during the upward movement of the blocking column 14, the convex plate 16 begins to contact the second spring 18. The second spring 18 surrounds and is sleeved on the insertion rod 17, and the insertion rod 17 is firmly inserted into the inside of the material box body 1. Due to the contact between the convex plate 16 and the second spring 18, the second spring 18 begins to be squeezed and exhibits a rebound force. This force will generate a reaction force during the movement of the blocking column 14. When the material placement frame 4 is fully inserted into the inside of the material box body 1, the blocking column 14 will automatically return to the initial position under the action of the rebound force of the second spring 18.

[0047] At this point, the side of the blocking column 14 facing away from the rounded corner 15 is designed as a straight surface. This design allows the straight surface to make close contact with the edge of the material placement frame 4, thereby effectively restricting the sliding of the material placement frame 4 inside the material box body 1. This mechanism not only ensures the stability of the frame insertion, but also ensures that the material placement frame 4 will not be displaced due to external force or vibration during use, further improving the use effect and greatly improving the accuracy and safety of material handling. The realization of this innovative design not only improves production efficiency, but also reduces the risks caused by improper operation or equipment failure.

[0048] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
