Description

Technical Field

[0001] This utility model belongs to the field of tray technology, and specifically relates to a tray for placing chips to be tested. Background Technology

[0002] A tray, also known as a chip tray, is a professional packaging tool used by semiconductor packaging and testing companies for chip packaging and testing. It is mainly used to store and protect chips, ensuring that they are not affected by static electricity, humidity, or other environmental factors during the packaging and testing process.

[0003] Currently, Chinese utility model patent CN217146745U discloses a tray. Although this tray has high strength and good load-bearing capacity, and multiple trays can be stacked, there are still other problems during use. For example, it is not easy to separate and pick up the trays. When two trays are stacked to the bottom, the outer edges will be tightly pressed together. Even if a notch is made on the outer surface, the width of the outer edge limits the depth to which a person can insert their fingers, making it difficult to pull them up. Therefore, tools are often required to assist, which reduces the efficiency of the workers. Moreover, it is not convenient to replace the internal dividers individually. The dividers are used to classify the chips. During the production of the tray, the internal dividers are integrally injection molded. Although this is stable, when the dividers are damaged and local damage occurs, the corresponding chips cannot be placed, which affects the overall layout. Replacing the entire tray would increase the economic cost for the user. Utility Model Content

[0004] The purpose of this invention is to provide a tray for placing chips for testing, which has the advantages of being easy for personnel to separate and handle, and easy to replace damaged separators individually.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tray for placing a chip to be tested, comprising a substrate, a boss integrally injection molded on the top of the substrate, a fixing frame placed inside the boss, a partition plate integrally injection molded inside the fixing frame, a recess integrally injection molded on the bottom of the substrate, a limiting frame placed on the top of the boss, four fixing bolts passing through the top of the limiting frame, and a threaded hole for cooperating with the fixing bolts on the top of the boss.

[0006] The above technical solution allows for easy replacement of damaged separators individually. The modular assembly method ensures overall stability and flexibility, reduces the economic burden of replacement, facilitates easy handling by personnel, simplifies operation, eliminates the need for tools, improves work efficiency, and is highly practical.

[0007] The present invention is further configured such that the top of the limiting frame is provided with a stepped groove for use with the fixing bolt, and the number of the stepped grooves is four.

[0008] The above technical solution is adopted: by setting the stepped groove, after the fixing bolt passes through and is screwed into the threaded hole, the head of the fixing bolt will be inside the stepped groove, thus avoiding the head of the fixing bolt being higher than the top of the limit frame and causing obstruction.

[0009] The present invention is further configured such that the depth inside the recessed platform is greater than the sum of the lengths of the protrusion and the limiting frame.

[0010] The above technical solution can prevent the chip inside the boss from contacting the bottom of the substrate and causing wear when the upper tray is stacked on the lower layer.

[0011] The present invention is further configured such that the length and width of the boss are the same as those of the limiting frame, and the inner diameter of the limiting frame is greater than the inner diameter of the boss.

[0012] The above technical solution can cover the top of the fixed frame placed inside the boss, preventing the fixed frame from shaking or shifting up and down.

[0013] The present invention is further provided that the interior of the recessed platform is provided with an oblique pathfinding groove.

[0014] The above technical solution allows for easy positioning and stacking of trays by personnel through the setting of inclined path-finding grooves.

[0015] The present invention is further provided that both sides of the substrate are rounded and chamfered.

[0016] The above technical solution can protect the safety of workers and prevent sharp edges from scratching them.

[0017] The present invention is further configured such that the substrate, boss, fixing frame, partition plate, recess and limiting frame are all made of PP material.

[0018] The above technical solution features a substrate, boss, fixing frame, partition plate, recess, and limiting frame with good heat resistance, capable of withstanding high-temperature environments, and good rigidity, making it suitable for bearing heavy objects.

[0019] In summary, this utility model has the following beneficial effects: 1. During installation, place the substrate on the table with the side with the boss facing up. Then, lift the fixing frame and place it into the boss. After placing the fixing frame, press it down to ensure that its bottom is fully in contact with the substrate. After the fixing frame is in place, lift the limiting frame and place it on the boss, aligning it with the outside of the boss. Once the limiting frame is aligned with the boss, it will cover the internal fixing frame. Then, lift the fixing bolt and insert it into the stepped groove. Finally, use a tool to turn the fixing bolt until it is screwed into the threaded hole. This method allows for easy replacement of damaged partition strips. The assembly method ensures overall stability and flexibility and reduces the economic burden of replacement when damaged. 2. By placing the chips to be tested in an orderly manner into the separator, the bottom of the chips will fall onto the substrate after placement. When the substrate is full, another substrate is picked up and placed face down on the current substrate. When the upper substrate is placed down, the inclined path-finding groove in the recess will cover the limiting frame of the lower substrate. Since the inclined path-finding groove is designed to be angled towards the center, after the upper substrate is placed and slids, the limiting frame will pass through the inclined path-finding groove and enter the recess. When separation is required, a finger can be inserted between the two substrates and pulled up. This makes it easy for personnel to separate and pick up the chips. The operation is simple and convenient, eliminating the need for tools and improving the work efficiency of personnel. It is highly practical. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1: refer to Figure 1 and Figure 2A tray for placing chips under test includes a substrate 1. The top of the substrate 1 has an integrally molded boss 2, and a fixing frame 3 is placed inside the boss 2. A partition plate 4 is integrally molded inside the fixing frame 3. The bottom of the substrate 1 has an integrally molded recess 5. By orderly placing the chips under test into the partition plate 4, the bottom of the chips will fall onto the substrate 1 after placement. When the substrate 1 is full, another substrate 1 is picked up. After picking up the other substrate 1, the recess 5 is placed face down on the current substrate 1. When the upper substrate 1 is placed down, the inclined path-finding groove 9 in the recess 5 will cover the limiting frame 6 of the lower substrate 1. Since the inclined path-finding groove 9 is designed to be inclined towards the center, after the upper substrate 1 is placed and slids, the limiting frame 6 will enter the recess 5 through the inclined path-finding groove 9. When separation is required, a finger can be inserted between the two substrates 1 and pulled up. This makes it easy for personnel to separate and pick up the chips. The operation is simple and convenient, eliminating the need for tools and improving the work efficiency of personnel. It is highly practical.

[0024] refer to Figure 1 and Figure 2 The recessed platform 5 has an inclined path-finding groove 9 inside, which makes it easier for personnel to position and stack the trays.

[0025] refer to Figure 1 and Figure 2 Both sides of the substrate 1 are rounded and chamfered to protect the safety of the operators and prevent sharp edges from scratching them.

[0026] Brief description of the usage process: By placing the chips to be tested in the separator plate 4 in an orderly manner, the bottom of the chips will fall onto the substrate 1 after placement. When the substrate 1 is full, pick up the other substrate 1. After picking up the other substrate 1, place the recess 5 face down on the current substrate 1. When the upper substrate 1 is placed down, the inclined path-finding groove 9 in the recess 5 will cover the limiting frame 6 of the lower substrate 1. Since the inclined path-finding groove 9 is designed to be inclined towards the center, after the upper substrate 1 is placed and slid, the limiting frame 6 will pass through the inclined path-finding groove 9 and enter the recess 5. When separation is required, simply insert your finger between the two substrates 1 and pull them up.

[0027] Example 2: refer to Figure 1 , Figure 2 and Figure 3A tray for placing chips under test is provided. A limiting frame 6 is placed on the top of the boss 2. Four fixing bolts 8 are provided through the top of the limiting frame 6. The top of the boss 2 has threaded holes 7 that cooperate with the fixing bolts 8. During installation, the substrate 1 is placed on the table with the side with the boss 2 facing up. Then, the fixing frame 3 is lifted and placed into the boss 2. After the fixing frame 3 is placed, it is pressed down to make its bottom fully fit the substrate 1. After the fixing frame 3 is placed, the limiting frame 6 is lifted and placed on the boss 2 and aligned with the outside of the boss 2. After the limiting frame 6 is aligned with the boss 2, it will cover the internal fixing frame 3. Then, the fixing bolts 8 are lifted and inserted into the stepped groove 10. Finally, the fixing bolts 8 are turned with a tool to screw them into the threaded holes 7. This method can facilitate the individual replacement of damaged separator strips 4. The assembly method can ensure the overall stability and flexibility and reduce the economic burden when replacing damaged parts.

[0028] refer to Figure 1 and Figure 3 The top of the limiting frame 6 is provided with a stepped groove 10 for use with the fixing bolt 8. There are four stepped grooves 10. By setting the stepped grooves 10, the head of the fixing bolt 8 will be inside the stepped groove 10 after it passes through and is screwed into the threaded hole 7, thus preventing the head of the fixing bolt 8 from being higher than the top of the limiting frame 6 and causing obstruction.

[0029] refer to Figure 1 The depth of the recess 5 is greater than the sum of the lengths of the protrusion 2 and the limiting frame 6, which can prevent the chip inside the protrusion 2 from contacting the bottom of the substrate 1 and causing wear when the upper tray is stacked on the lower layer.

[0030] refer to Figure 1 The length and width of the boss 2 are the same as those of the limiting frame 6. The inner diameter of the limiting frame 6 is larger than that of the boss 2, which can block the top of the fixing frame 3 placed inside the boss 2, and prevent the fixing frame 3 from shaking or shifting up and down.

[0031] refer to Figure 1 , Figure 2 and Figure 3 The substrate 1, boss 2, fixing frame 3, partition plate 4, recess 5 and limiting frame 6 are all made of PP material. The substrate 1, boss 2, fixing frame 3, partition plate 4, recess 5 and limiting frame 6 have good heat resistance, can withstand high temperature environment, have good rigidity and are suitable for bearing heavy objects.

[0032] Brief description of the usage process: During installation, place the substrate 1 on the table with the side with the boss 2 facing upwards. Then, pick up the fixing frame 3 and place it into the boss 2. After the fixing frame 3 is placed, press it down to the bottom so that its bottom is fully in contact with the substrate 1. After the fixing frame 3 is in place, pick up the limiting frame 6 and place it on the boss 2, aligning it with the outside of the boss 2. After the limiting frame 6 is aligned with the boss 2, it will cover the internal fixing frame 3. Then, pick up the fixing bolt 8 and insert it into the stepped groove 10. Finally, use a tool to rotate the fixing bolt 8 to screw it into the threaded hole 7.

[0033] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
