Description

Technical Field

[0001] This utility model relates to the technical field of electronic component processing, and in particular to a conveying mechanism for electronic component testing. Background Technology

[0002] In the process of testing semiconductor electronic components, the testing of electronic components is generally carried out in a testing environment with a suitable temperature, such as a low temperature environment below zero degrees Celsius.

[0003] Existing semiconductor component testing equipment typically includes an external handling mechanism, a cooling mechanism, a constant temperature chamber, and an internal handling and testing mechanism located within the constant temperature chamber. Since the external handling mechanism is generally located in a room-temperature environment outside the constant temperature chamber, condensation can occur on both the electronic components and the external handling mechanism during the process of moving the cooled electronic components from the cooling mechanism to the constant temperature chamber. This can affect subsequent testing of the electronic components and may also adversely affect the testing mechanism.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a conveying mechanism for electronic component testing, making it more valuable for industrial applications. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a conveying mechanism for testing electronic components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A conveying mechanism for testing electronic components includes a machine base and several trays, cooling tables, testing tables and temporary storage tables located on the machine base. A first conveying mechanism is provided between the trays and the cooling tables, a second conveying mechanism is provided between the cooling tables and the testing tables, the testing tables are located inside a constant temperature testing chamber and a third conveying mechanism is also provided inside the constant temperature testing chamber, and the first conveying mechanism is provided between the testing tables and the temporary storage tables.

[0008] The first, second, and third handling mechanisms all include a handling lifting cylinder mounted on a multi-axis robotic arm. The drive end of the handling lifting cylinder at the bottom is connected to the handling component below via a handling lifting rod.

[0009] The second handling mechanism also includes a handling cover located outside the handling lifting cylinder;

[0010] The handling assembly includes a handling base installed at the bottom of the handling lifting rod, a suction cup installed on the top inner side of the handling base, and a clearance groove provided between the suction cup and the bottom of the handling base;

[0011] An entrance / exit is provided on the outer cover directly below the transport base, allowing the transport base to move freely in and out, and the entrance / exit is equipped with a closed structure.

[0012] As a further improvement of this utility model, in the constant temperature test hoods on both the left and right sides of the test platform, there are inlet and outlet conveyor belts adapted to the third conveying mechanism. On the constant temperature test hood on the top side of the inlet and outlet conveyor belt, there are inlets and outlets for the conveying base to freely enter and exit, and there are closed structures on the inlets and outlets.

[0013] As a further improvement of this utility model, the sealing structure includes a side-push cylinder, a side-push rod, a side-push linkage rod, and a valve plate. A movable cavity for the valve plate to move freely is provided on one side of the inlet and outlet. The driving end of the side-push cylinder drives the side-push rod and drives the valve plate to move left and right through the side-push linkage rod, thereby realizing the sealing and opening of the inlet and outlet.

[0014] As a further improvement of this utility model, a slot for the valve plate to be engaged is provided at the inlet and outlet on the side away from the side thrust cylinder.

[0015] As a further improvement of this utility model, a protruding structure facing downward is provided at the edge of the bottom of the suction cup.

[0017] As a further improvement of this utility model, a polyurethane foam insulation layer is wrapped around the outside of the transport cover, and the suction cup is made of silicone rubber.

[0018] By means of the above solution, this utility model has at least the following advantages:

[0019] The transport cover on the second transport mechanism of this utility model can keep the electronic components warm during the transport process, and the transport base on the outside of the suction cup can easily allow the suction cup to freely enter and exit the bottom of the transport cover, making it convenient to grab the electronic components and avoid affecting them.

[0020] This invention utilizes a raised structure on the contact surface at the bottom of the suction cup to enable electronic components to make close contact with the suction cup, and the contact area is evenly distributed, thereby improving adsorption stability and heat preservation effect.

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] 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 of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] The first embodiment of this utility model:

[0033] like Figures 1-5 The present invention relates to an electronic component handling and testing device, which mainly includes a machine base 1 and a tray 2, a first handling mechanism 3, a cooling platform 4, a second handling mechanism 5, a constant temperature test hood 6, a test platform 7, a third handling mechanism 8, an inlet and outlet conveyor belt 9, and a temporary storage platform 10 installed on the machine base 1.

[0034] Several trays 2 are evenly distributed along the left-right direction at the front end of the machine 1. These trays 2 can move on the machine 1 along both the left-right and front-back directions. Figure 1 The movement trajectory of the tray 2 can be as follows: an electronic component 23 is placed on the tray 2 on the front right side, and then the tray 2 with the electronic component 23 moves to the left and then to the rear, thereby adapting to the cooling platform 4. The electronic component 23 on the tray 2 is transported to the cooling platform 4 for cooling by the first conveying mechanism 3. Then the tray 2 moves to the right and then to the front until it returns to the initial position, which is a cycle.

[0035] The test bench 7 is located at the rear center of the machine 1, with a cooling platform 4 and a temporary storage platform 10 on its left and right sides, respectively. When the tray 2 carrying the electronic component 23 moves to a position close to the cooling platform 4, the first conveying mechanism 3 on the left transports the electronic component 23 onto the cooling platform 4 for cooling. After cooling, the second conveying mechanism 5 transports the electronic component 23 onto the in-out conveyor belt 9 on the left side of the test bench 7, and then the third conveying mechanism 8 transports the electronic component 23 back to the test bench 7 for testing. After testing, the electronic component 23 is transported by the third conveying mechanism 8 onto the conveyor belt 9 on the right side of the test bench 7, and then the first conveying mechanism 3 on the right transports the electronic component 23 to the temporary storage platform 10 for temporary storage. The cooling, transporting, and testing processes described above are all existing technologies in the field.

[0036] The first transport mechanism 3, the second transport mechanism 5, and the third transport mechanism 8 described above all include a multi-axis robotic arm 11, a transport lifting cylinder 13, a transport lifting rod 14, and a transport assembly 15. Furthermore, the second transport mechanism 5, compared to the first transport mechanism 3 and the third transport mechanism 8, also includes a transport cover 12 located outside the transport lifting cylinder 13, and the mounting structure of the suction cup 25 in the transport assembly 15 is also different. In the first transport mechanism 3 and the third transport mechanism 8, the suction cup 25 is simply mounted on the bottom of the transport base 24.

[0037] Specifically, the transport base 24 is installed at the bottom of the transport lifting rod 14, and a suction cup 25 is installed on the top inner side of the transport base 24. A clearance groove 26 is provided between the suction cup 25 and the bottom of the transport base 24.

[0038] An inlet / outlet 21 for the transport base 24 to freely enter and exit is provided on the transport cover 12 directly below the transport base 24, and a sealing structure is provided on the inlet / outlet 21. The sealing structure includes a side-push cylinder 16 installed on the bottom right side of the transport cover 12 and the transport base 24. During operation, the transport lifting cylinder 13 drives the transport lifting rod 14 and causes the transport base 24 to descend. At the same time, the side-push cylinder 16 drives the side push rod 17 and the side push linkage rod 18 and causes the valve plate 20 located at the inlet / outlet 21 to move toward the movable cavity 19 on the right, so that the inlet / outlet 21 opens. Then the transport base 24 continues to descend and grabs the electronic component 23 located on the cooling platform 4. After that, the transport base 24 rises to its original position, and the side push cylinder 16 drives the side push rod 17 and the side push linkage rod 18 and causes the valve plate 20 located in the movable cavity 19 to return to the inlet / outlet 21, thus completing the sealing of the inlet / outlet 21 again.

[0039] During this process, the clearance groove 26 at the transport base 24 protects the internal suction cup 25 to prevent other working parts from affecting the electronic component 19 and causing it to fall off.

[0040] In addition, both sides of the test bench 7 are equipped with inlet and outlet conveyor belts 9 that are compatible with the third conveying mechanism 8. The inlet and outlet 21 for the conveying base 24 to freely enter and exit is opened on the temperature-controlled test chamber 6 on the top side of the inlet and outlet conveyor belt 9, and the inlet and outlet 21 is equipped with a closed structure. The working process is the same as described above, and will not be repeated here.

[0041] The second embodiment of this utility model:

[0042] like Figure 5A downward-facing protrusion structure 27 is provided at the bottom edge of the suction cup 25. The protrusion structure 27 is an arc-shaped structure. Through the protrusion structure on the contact surface at the bottom of the suction cup, the electronic components can closely contact the suction cup, and the contact area is evenly distributed, thereby improving the adsorption stability and heat preservation effect.

[0043] In addition, a polyurethane foam insulation layer is wrapped around the outside of the handling cover 12 to reduce heat loss and transfer, and maintain the overall temperature stability of the handling mechanism. The suction cup 25 is made of silicone rubber. Silicone rubber has a low thermal conductivity, good flexibility and certain strength, and can adapt to the surface of electronic components 23 of different shapes, while reducing heat transfer.

[0044] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
