After the first test is completed, the chip in the failure retest area is placed in the test area through the mechanical arm, thereby achieving the purpose of automatic retesting and reducing the time of manual re-placement and test machine downtime. The inventor found the following problems in the prior art during the implementation of the utility model:

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] As attached Figures 1 to 4 A clamp for a re-measurement structure shown in FIG. 1 includes a base plate 1, which is usually made of high-strength metal materials such as steel or aluminum alloy to ensure sufficient bearing capacity and stability. Upper clamps 2 are provided on both sides of the base plate 1. Before operation, the upper clamps 2 are fixed at a predetermined position by a structural frame 9. When an empty disc is fed into the material area, the sliding plate 10 drives the sensor 11 to move to an appropriate position, which is precisely controlled by the sensor 11 so that the clamping groove 12 can accurately clamp the empty disc. Once the empty disc is clamped, the upper clamp 2 will not be loosened throughout the process, thereby ensuring the stability and safety of the material during transportation and re-measurement. This design enables the upper clamp 2 to accurately and stably clamp the empty disc, thereby maintaining the integrity and safety of the material during the entire operation and avoiding damage or spillage of the material due to unstable clamping.

[0025] A connecting wire 3 is provided at the bottom of the upper clamping jaw 2. The connecting wire 3 is provided at the bottom of the upper clamping jaw 2. One end of the connecting wire 3 is connected to the bottom of the upper clamping jaw 2, and the other end is connected to other necessary systems or components to realize signal transmission, power supply or other necessary functions. The main function of the connecting wire 3 is to transmit control signals and / or power. In the automation equipment, the connecting wire 3 ensures that the electric control components of the upper clamping jaw 2 can receive instructions from the control system and perform corresponding operations. The lower clamping jaw 4 is provided on both sides of the upper clamping jaw 2. There are four groups, and the four groups of lower jaws 4 are evenly arranged in the horizontal direction of the bottom plate 1. When the lower jaws 4 need to clamp an empty tray, the slider 14 drives the jaw 13 body to move to the specified position. Once it reaches the appropriate position, the jaw 13 body performs a clamping action and firmly grasps the plate. In the retest operation, the lower jaw 4 first clamps the tray with the material, and then forms a closed structure with the empty tray clamped by the upper jaw 2 to ensure the safety and stability of the material during the movement. After completing the task, the lower jaw 4 releases the clamping, while the upper jaw 2 remains clamped and continues to carry. Empty disk, the design of the lower clamp 4 enables it to flexibly respond to different operational requirements. No matter it is clamping an empty disk or cooperating with the upper clamp 2 for retesting operation, it can ensure that the task is completed efficiently and safely. By accurately controlling the movement of the slider 14, the lower clamp 4 can be accurately positioned, which improves the accuracy and reliability of the operation. A control mechanism 5 is provided on one side of the lower clamp 4. The control mechanism 5 receives instructions from a higher-level control system through an antenna 16. These instructions can be specific commands about the position, clamping force, moving speed, etc. of the two sets of clamp devices. The control module 15 analyzes these instructions and converts them into specific control signals. These signals guide the clamp 13 to perform precise operations, such as adjusting the position, changing the clamping state, etc. After the operation is completed, the control module 15 can feedback the completion status or any error information to the upper control system through the antenna 16 for real-time monitoring and adaptive adjustment. The introduction of the control mechanism 5 significantly improves the intelligence and automation level of the clamp system. Through precise external control and real-time feedback, the system can more flexibly respond to different operational requirements and unforeseen situations.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 4 As shown, see the following description for details:

[0028] As a preferred embodiment, the bottom plate 1 is a gantry structure, which is rectangular. The bottom plate 1 includes a protective plate 6, a pillar 7 and a crossbeam 8. The four corners of the protective plate 6 are provided with pillars 7, and the two sides of the pillars 7 are provided with crossbeams 8. The crossbeams 8 can be displaced inside the protective plate 6 along the vertical direction of the pillars 7. Furthermore, the bottom plate 1 provides a stable and solid platform through its gantry structure, so that the upper clamping jaws 2 and the lower clamping jaws 4 can slide and position smoothly along the crossbeams 8. The bottom plate 1 with a gantry structure enhances the stability and reliability of the entire clamping jaw system. Its solid structure ensures safety performance under long-term operation and high-intensity operating conditions, and protects The plate 6 is usually made of a rigid and impact-resistant material, such as high-strength plastic or metal, to enhance its protective performance. The pillar 7 is usually made of a strong material such as steel or aluminum. The shape and size design must take into account the load-bearing requirements and coordination with the base plate and the protective plate. The pillar 7 is an important part of the gantry structure and is responsible for supporting the crossbeam 8 and maintaining the stability of the entire clamping system. The crossbeam 8 connects the pillars 7 on both sides to provide sliding tracks for the upper clamping jaw 2 and the lower clamping jaw 4 so that they can move smoothly along a specific path. The crossbeam 8 needs to have sufficient hardness and flatness to ensure smooth and precise movement of the clamping jaws. It is usually made of precision-processed metal or high-performance synthetic materials.

[0029] As a preferred embodiment, the upper clamp 2 includes a structural frame 9, a sliding plate 10, a sensor 11 and a clamping groove 12. The sliding plate 10 is provided on one side of the structural frame 9, the sensor 11 is provided on one side of the sliding plate 10, and the clamping groove 12 is provided on one side of the sliding plate 10. The shape of the clamping groove 12 is consistent with the tray. Further, the structural frame 9 is usually made of lightweight and high-strength materials (such as aluminum alloy or high-strength plastic) to reduce the overall weight and maintain good mechanical properties. The design of the structural frame 9 should take into account the load-bearing capacity and durability, and ensure that all installation holes and connection parts are accurate so as to be smoothly integrated with other components (such as sliding plates and sensors). The sliding plate 10 is usually equipped with a bearing or slider with a low friction coefficient to reduce resistance during movement and improve positioning accuracy. The sensor 11 is used to detect the position and clamping force of the clamping claw to ensure precise control. Various types of sensors 11 can be used, including photoelectric sensors, pressure sensors or displacement sensors, etc., and appropriate models and specifications are selected according to needs. The sensor 11 should be installed in key positions, such as near the contact point of the sliding plate 10. The clamping groove 12 is the part that actually contacts and clamps the pallet. Its shape should match the design of the pallet to ensure stable clamping. It is usually made of wear-resistant and elastic materials, such as high-strength plastic or metal covered with anti-slip rubber and other materials.

[0030] As a preferred embodiment, the lower layer clamp 4 includes a clamp 13 and a slider 14. The slider 14 is provided on one side of the clamp 13, and one side of the slider 14 is connected to the beam 8. Furthermore, the clamp 13 is usually made of wear-resistant material, such as carbide, high-strength plastic or metal covered with an anti-slip coating to improve its durability and grasping stability. Its shape design should conform to ergonomic principles to ensure that it can accurately match the surface of the material or pallet. The opening and closing action of the clamp 13 can be achieved by electric, pneumatic or hydraulic drive. The specific selection depends on the application requirements and equipment design. The slider 14 is usually equipped with a low-friction bearing or sliding element, such as a roller or a sliding pad, to reduce movement resistance and improve positioning accuracy. The slider 14 is fixed to the beam 8 by mechanical fasteners or a quick-change mechanism.

[0031] As a preferred implementation, an empty tray is fed in before the operation so that the upper clamp 2 clamps the empty tray without releasing it during the entire operation. Furthermore, by feeding in an empty tray before the operation and clamping it by the upper clamp 2, the clamping state is maintained during the entire operation process, which can greatly reduce the shaking or displacement of the material during the movement and re-measurement. This design significantly enhances the stability of the entire mechanical system during operation. This design method enables the equipment to adapt to a variety of different types and scales of material handling needs, and has strong versatility and adaptability. Whether it is light or heavy materials, this mechanism can be relied upon to achieve stable and efficient transfer and re-measurement.

[0032] As a preferred embodiment, the lower jaws 4 clamp the empty tray and then transport the empty tray through the crossbeam 8. After the lower jaws 4 clamp the tray with materials, they form a closed structure with the empty tray clamped by the upper jaws 2, and the closed structure formed by the lower jaws 4 and the upper jaws 2 remains closed throughout the entire process of material production, transportation, and sales. Furthermore, by forming a stable closed structure, the safety of materials in the entire process of production, transportation and sales is ensured. This design effectively prevents the spillage or damage of materials during handling. The lower jaws 4 work together with the upper jaws 2 to optimize the workflow, reduce the time wasted due to replacement or adjustment of the jaws, and improve the efficiency and accuracy of the operation. Since the materials are kept in the closed structure throughout the entire process, the stability and reliability of the system are greatly enhanced, and the risk of material loss due to external factors is reduced.

[0033] As a preferred embodiment, the control mechanism 5 includes a control module 15 and an antenna 16. The top of the control module 15 is provided with an antenna 16. Furthermore, the control module is the core of the entire control system, responsible for receiving external instructions, processing signals, and issuing corresponding control commands to drive the gripper and other related components. It usually includes a microprocessor, a memory, and an interface circuit, etc., which can quickly respond and execute complex operation logic, and is used to receive wireless instructions from a higher-level control system or transmit status information back to the upper-level control system. It can be a built-in or external antenna, and the appropriate type is selected according to specific needs. The built-in antenna is installed inside the device, while the external antenna is installed outside the device for easy debugging and maintenance.

[0034] The working process of the utility model is as follows: first, before the operation, an empty tray is sent into the material area. The upper clamping jaws 2 are not released during the whole process after clamping. The lower clamping jaws 4 are used during the intermediate actuation process. If the empty tray is clamped (a common action of current equipment), the lower clamping jaws 4 will not move to the upper layer after clamping the empty tray (the Z axis will not move close to the upper clamping jaws 2), and only transport the empty tray. If the re-measurement action is performed, the lower clamping jaws 4 will first clamp the plate and then move and fit with the upper clamping jaws 2 to form a closed structure of the material in the upper and lower tray plates (the material is in the closed structure throughout the entire process of production, transportation and sales, so the stability of the structure does not need to be demonstrated) and then move. After reaching the position, the lower clamping jaws 4 will release the clamping jaws, and the tray plate of the upper clamping jaws 2 will not be released and will be taken away. The above is the working principle of the clamping jaws used for the re-measurement structure.
