Description

Technical Field

[0001] This utility model belongs to the field of chip test board pressing and conveying technology, and specifically relates to a chip test board pressing and conveying device. Background Technology

[0002] IC chips typically require programming and testing during the manufacturing process, which necessitates the use of programming equipment. When the programming equipment is in operation, it uses a corresponding pressure plate to press down, causing the socket (chip connector) of the programming equipment to connect with the IC chip.

[0003] Traditional programming and testing methods are static tests, which require the entire equipment to stop operating. After testing, the test board needs to be manually disassembled and moved externally. This testing and transportation process is time-consuming, affecting production efficiency. Furthermore, the equipment shutdown hinders the collection and refinement of dynamic data, and does not meet the requirements for energy-efficient production.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0029] The following provides a brief overview of one or more aspects to offer a basic understanding of them. This overview is not an exhaustive summary of all conceived aspects, nor is it intended to identify key or decisive elements of all aspects, nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form to prepare for the more detailed descriptions that follow.

[0030] Example:

[0031] like Figures 1-7 As shown, a chip test board pressing and conveying device includes a base 1, a pressing device 2 disposed on the base 1, and a carrier plate 3. The carrier plate 3 is used to place the test board 4. The base 1 is also provided with a lifting mechanism 5 for driving the test board 4 to rise and fall, and a moving mechanism 6 for driving the carrier plate 3 to move.

[0032] In this embodiment, as a specific solution, the lifting mechanism 5 includes a support base 51, a lifting cylinder 52 disposed on the support base 51, and a linear bearing 53. The support base 51 is disposed below the base 1, and the bearing plate 3 is disposed above the base 1. The linear bearing 53 passes through the base 1 and the bearing plate 3 and then contacts the test plate 4. The lifting cylinder 52 drives the linear bearing 53 to rise and fall to drive the test plate 4 to rise and fall.

[0033] In this embodiment, as a more specific solution, the lifting cylinder 52 is an ultra-thin cylinder.

[0034] In this embodiment, as a more specific solution, the linear bearing 53 is provided in four groups, and the four groups of linear bearings 53 are distributed along the outer periphery of the four corners of the lifting cylinder 52.

[0035] In this embodiment, as a more specific solution, the bottom of the support plate 3 is provided with a groove structure 31. The linear bearing 53 passes through the base 1 and then through the support plate 3 from the groove structure 31, and then contacts the test plate 4 on the support plate 3. As the lifting cylinder 52 pushes the linear bearing 53 to move up and down, it pushes the test plate 4 to move up and down.

[0036] In this embodiment, as a more specific solution, the thickness of the support plate 3 of the groove structure 31 becomes thinner at this position, and the linear bearing 53 passes through this position and contacts the test plate 4. When the lifting cylinder 52 drives the linear bearing 53 to rise and fall, its movement resistance in the support plate 3 is smaller, making it easier for the lifting cylinder 52 to work.

[0037] In this embodiment, as a specific solution, the moving mechanism 6 includes a guide shaft 61 disposed on the base 1 and a rodless cylinder 62 disposed on the guide shaft 61. The rodless cylinder 62 is connected to the support plate 3, and the rodless cylinder 62 drives the support plate 3 to move on the guide shaft 61.

[0038] In this embodiment, as a more specific solution, the pressing device 2 includes a pressing frame 21 disposed on the base 1, a pressure plate 22 disposed on the pressing frame 21, and the bearing plate 3 located below the pressure plate 22.

[0039] In this embodiment, as a more specific solution, the pressure plate 22 is assembled from several pressure plate modules 221.

[0040] In this embodiment, as a more specific solution, the pressure plate 22 has a downward force. When the test plate 4 is raised to a suitable height, the pressure plate 22 presses down to open the socket on the test plate 4 (this technical data is existing technology and will not be described in detail here). The downward force can be provided by setting an elastic element 23. More specifically, an elastic element 23 can be set on the pressing frame 21 and connected to the pressure plate 22 through the elastic element 23; more specifically, the elastic element can be a spring.

[0041] In this embodiment, as a specific solution, the base 1 is provided with a guide plate 7, and the guide shaft 61 is disposed on the guide plate 7.

[0042] In this embodiment, as a specific solution, the guide plate 7 is detachably mounted on the base 1.

[0043] In this embodiment, as a specific solution, the base 1 is also provided with a rodless cylinder limiting device 8.

[0044] In this embodiment, as a more specific solution, the rodless cylinder limiting device 8 includes a guide post 81 and a limiting block 82 connected to the guide post 81. When the limiting block 82 contacts the rodless cylinder 62, it limits the rodless cylinder 62.

[0045] In this embodiment, as a more specific solution, the limiting block 82 is made of a soft material.

[0046] In this embodiment, as a specific solution, a limiting mechanism 9 is also provided between the support base 51 and the base 1.

[0047] In this embodiment, as a more specific solution, the limiting mechanism 9 includes a limiting plate 91, which is connected to the bottom of the base 1. The limiting plate 91 is provided with a limiting pin 92. The support base 51 rises with the linear bearing 53 until it touches the limiting pin 92. This structural design plays a certain role in limiting the range of vertical movement of the linear bearing 53, so as to prevent the test plate 4 from damaging the pressing device 2.

[0048] The working principle of this utility model is as follows:

[0049] The workpiece 10 to be programmed and tested is placed on the test board 4, which is placed on the support plate 3. The base 1 can be connected to the previous process in chip manufacturing, and the guide shaft 61 can also be connected to the previous process (the previous process is not covered by this application and will not be described in detail). The test board 4, with the workpiece on it, enters the support plate 3 inside the pressing frame 21 from the previous process. The lifting cylinder 52 works to cause the linear bearing 53 to pass through the support plate 3 and push the test board 4 upward. When the test board 4 is lifted... When the pressure plate 22 reaches the appropriate position (also known as the pressing and opening height), it presses down to perform burning and testing operations. After completion, the lifting cylinder 52 works again to cause the test plate 4 to descend onto the support plate 3. Then, the rodless cylinder 62 works to drive the support plate 3 to move on the guide shaft 61, thereby transporting the test plate 4 to the outside of the pressing device 2. The robot arm grabs the test plate 4 to the next station, while the support plate 3 is driven by the rodless cylinder 62 to return to its position inside the pressing frame 21 to wait for the next test plate. This process is repeated.

[0050] This utility model has the following advantages:

[0051] 1. This utility model, through the cooperation of a lifting mechanism and a moving mechanism, can realize the lifting and moving of the test board, so that the testing and transfer operations can be completed without stopping the equipment, thereby improving production efficiency;

[0052] 2. This utility model is equipped with a rodless cylinder limiting device, which can limit the movement range of the support plate and ensure the safety of the rodless cylinder during operation.

[0053] 3. This utility model is safe and reliable, has a certain aesthetic appeal, and can meet the needs of energy-saving production.
