Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, specifically to a high-efficiency feeding mechanism. Background Technology

[0002] With the development of electronic technology, chips are becoming increasingly integrated, with increasingly finer structures, more and more processes, and increasingly complex manufacturing processes. Inevitably, some latent defects will be generated in the chips during the manufacturing process, and these defects usually need to be operated for about a thousand hours before they are fully exposed.

[0003] Therefore, the current main method to accelerate defect exposure is to conduct chip environmental adaptability testing. Environmental adaptability testing usually adopts three-temperature testing, which involves testing at three temperatures: low temperature, room temperature, and high temperature. These are generally defined as low temperature -55°C, room temperature 25°C, and high temperature 125°C.

[0004] When testing chips with a three-temperature testing device, the material tray needs to be pushed from the feeding module into a sealed high and low temperature environment. Then, the chips on the material tray are picked up one by one by the clamping mechanism and placed into the detection module (which is in the high and low temperature environment) for testing. The above feeding method requires placing the material on the material tray and then placing it into the detection module for temperature pretreatment. As a result, most of the surface of the material is blocked, which affects the temperature pretreatment.

[0005] In view of this, there is an urgent need for an efficient feeding mechanism to solve the above problems. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-efficiency feeding mechanism includes: a frame, a drive unit, a tray frame 1, a tray 2, and a tray 4;

[0009] The material tray 1 is slidably connected to the machine frame, and the driving component is used to drive the material tray 1 to slide along the machine frame;

[0010] The tray 2 is placed on the tray rack 1. The top surface of the tray 2 is provided with two parallel and spaced limiting plates 3. The space between the two limiting plates 3 is the tray placement space. The tray 2 is provided with a hollow hole 21 at the position corresponding to the tray placement space.

[0011] The material tray 4 is located in the material tray placement space. The material tray 4 is provided with a plurality of material grooves 41. The bottom of the material groove 41 is provided with a through hole that penetrates the material tray 4, and the through hole and the hollow hole 21 are provided correspondingly.

[0012] The tray rack is provided with several trays, which are arranged in parallel from bottom to top.

[0013] The frame is provided with two slide rails, which are arranged in parallel, and the tray frame is slidably mounted on the two slide rails.

[0014] Both limiting plates are provided with baffles at the same end, and the two baffles extend toward each other.

[0015] The limiting plate has a guide surface at one end away from the baffle. The guide surface is a plane and is perpendicular to the tray. The guide surface extends obliquely from the side near the baffle to the side away from the baffle, and the oblique direction is the side away from the tray placement space.

[0016] The tray has several rolling balls arranged within the material tray placement space.

[0017] The balls are arranged in two rows, and the arrangement direction of each row of balls is consistent with the extension direction of the limiting plate.

[0018] Several rollers are provided on both sides of the material tray near the two limiting plates.

[0019] The material tray is provided with a number of elastic elements, and a number of rollers are respectively disposed on the elastic elements. The elastic elements are used to apply elastic force to the rollers toward the side away from the material tray.

[0020] Each of the two limiting plates has a plurality of positioning grooves on one side that is close to each other, and the plurality of positioning grooves correspond one-to-one with the plurality of rollers.

[0021] The above-described structure of this utility model can achieve the following beneficial effects:

[0022] In use, the drive unit drives the tray frame away from the high and low temperature environment, and then a tray is placed in the tray placement space. The drive unit then drives the tray frame into the high and low temperature environment for the clamping mechanism to clamp the material on the tray. The high and low temperature environment simultaneously heats or cools the material on several trays. Because the tray has a perforated hole below the tray placement space, and the bottom of the trough has a through hole that passes through the tray, the bottom and top of the material in the trough are in direct contact with the high and low temperature environment, which improves the effect of temperature pretreatment.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0032] like Figures 1-3 As shown, a high-efficiency feeding mechanism includes: a frame, a drive unit, a tray frame 1, a tray 2, and a tray 4;

[0033] The tray frame 1 is slidably connected to the machine frame, and the driving component is used to drive the tray frame 1 to slide along the machine frame;

[0034] The tray 2 is placed on the tray rack 1. The top surface of the tray 2 is provided with two parallel and spaced limiting plates 3. The space between the two limiting plates 3 is the tray placement space. The tray 2 is provided with a hollow hole 21 at the position corresponding to the tray placement space.

[0035] The material tray 4 is located in the material tray placement space. The material tray 4 is provided with several material grooves 41. The bottom of the material groove 41 is provided with a through hole that passes through the material tray 4, and the through hole and the hollow hole 21 are provided in correspondence.

[0036] Based on the above structure, during use, the drive unit drives the tray frame 1 to leave the high and low temperature environment (detection chamber), and then a tray 4 is placed in the tray placement space. Then, the drive unit drives the tray frame 1 to enter the high and low temperature environment for the clamping mechanism to clamp the material on the tray 4. The high and low temperature environment simultaneously heats or cools the material on several trays 4. Since the tray 2 is provided with a hollow hole 21 below the tray placement space, and the bottom of the material trough 41 is provided with a through hole penetrating the tray 4, the bottom and top of the material in the material trough 41 are in direct contact with the high and low temperature environment, which improves the effect of temperature pretreatment.

[0037] Further optimization involves providing several trays 2 on the tray rack 1, arranged in parallel from bottom to top. In this embodiment, three trays 2 are provided. During use, the drive unit drives the tray rack 1 out of the high and low temperature environment (detection chamber), and then a tray 4 is placed in each tray placement space. The drive unit then drives the tray rack 1 back into the high and low temperature environment for the clamping mechanism to clamp the material on the tray 4. Since several trays 4 are provided on the tray rack 1, the clamping mechanism can clamp them sequentially, improving the feeding efficiency and reducing the frequency of pushing the trays 4.

[0038] like Figure 1 As shown, in order to guide and limit the movement of the material tray frame 1, two slide rails 5 are provided on the frame. The two slide rails 5 are arranged in parallel, and the material tray frame 1 is slidably mounted on the two slide rails 5, so that the material tray frame 1 can only move along the slide rails 5. The driving component can be a push rod, cylinder, etc.

[0039] like Figure 2 and Figure 3As shown, baffles 31 are provided at the same end of both limiting plates 3. The two baffles 31 extend toward each other and cooperate with the two limiting plates 3 to limit the three sides of the tray 4 to achieve the purpose of positioning the tray 4. In order to facilitate pushing the tray 4 into the tray placement space, a guide surface 32 is provided at the end of the limiting plate 3 away from the baffle 31. The guide surface 32 is flat and perpendicular to the tray 2. The guide surface 32 extends obliquely from the side near the baffle 31 to the side away from the baffle 31. The oblique direction is the side away from the tray placement space. In this way, the opening of the tray placement space away from the baffle 31 is funnel-shaped, which makes it easy to insert the tray 4 between the two limiting plates 3.

[0040] like Figure 3 As shown, in order to reduce the friction between the material tray 4 and the pallet 2, the pallet 2 is provided with several rolling balls 6 in the material tray placement space, and the rolling balls 6 are divided into two rows. The arrangement direction of each row of rolling balls 6 is consistent with the extension direction of the limiting plate 3, so that the material tray 4 and the pallet 2 are in rolling contact, which reduces the friction. In addition, the rolling balls 6 support the material tray 4, minimizing the contact area with the bottom of the material tray 4, so that the material tray 4 is suspended, which is conducive to contact with the environment and temperature pretreatment.

[0041] Further optimizations include, for example Figure 4 and Figure 5 As shown, several rollers 7 are provided on both sides of the material tray 4 near the two limiting plates 3. After the material tray 4 is pushed between the two limiting plates 3, there is rolling friction between the two sides of the material tray 4 and the two limiting plates 3. Several elastic elements 8 are provided on the material tray 4, and the rollers 7 are respectively disposed on the elastic elements 8. The elastic elements 8 are used to apply elastic force to the rollers 7 away from the material tray 4. After the material tray 4 enters between the two limiting plates 3, the rollers 7 on both sides move to one side of the material tray 4, compressing the elastic elements 8, so that the rollers 7 and the limiting plates 3 remain in contact. The two limiting plates 3 are provided with a number of positioning grooves 33 on the side that are close to each other. The number of positioning grooves 33 corresponds to a number of rollers 7. When one side of the material tray 4 abuts against the baffle 31, the number of rollers 7 are respectively engaged in the number of positioning grooves 33 to achieve positioning of the rollers 7, thereby achieving positioning of the material tray 4. The shape of the positioning grooves 33 is preferably V-shaped or arc-shaped so that after a certain pushing force is applied to the material tray 4, the rollers 7 can leave the positioning grooves 33, so that the material tray 4 can smoothly leave between the two limiting plates 3.

[0042] In summary, during use, the drive unit drives the tray frame 1 away from the high and low temperature environment, and then a tray 4 is placed in the tray placement space. Then, the drive unit drives the tray frame 1 into the high and low temperature environment so that the clamping mechanism can clamp the material on the tray 4. The high and low temperature environment simultaneously heats or cools the material on several trays 4. Since the tray 2 is provided with a hollow hole 21 below the tray placement space, and the bottom of the trough 41 is provided with a through hole that penetrates the tray 4, the bottom and top of the material in the trough 41 are in direct contact with the high and low temperature environment, which improves the effect of temperature pretreatment.

[0043] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
