Abstract
Description
Technical Field
[0001] This application relates to the field of chip testing technology, and in particular to a manipulator based on winch lifting, used to complete the lifting and lowering operation of the ATE test head. Background Technology
[0002] Traditional ATE test head manipulator mechanisms are mostly operated manually, which has the following drawbacks:
[0003] Large size: Traditional manipulators mostly drive the raising and lowering of the ATE test head by balancing with counterweights. In balancing, it is necessary to repeatedly add or remove counterweights to achieve balance before operation can be performed, which is cumbersome and inconvenient to use.
[0004] Poor portability: Traditional manipulators do not have wheels on the bottom and require other equipment to move them. They are also large and heavy.
[0005] No shock absorption structure: Some vibration is inevitable during the lifting operation, which affects the operation. Utility Model Content
[0006] A manipulator structure for raising and lowering the ATE test head is provided, which is labor-saving, self-locking, and highly safe. It achieves labor-saving by using a winch and improves safety by utilizing the self-locking characteristics of the winch. A manipulator based on winch lifting is characterized by comprising: a bracket (18), a pulley fixing plate (1), and a lifting eye bolt (6). The bottom of the bracket (18) is equipped with two load-bearing wheels (15) and two universal wheels (12). A winch fixing seat (10) is mounted on the bottom of the bracket (10). A winch (9) is installed above the fixing seat (10). A self-lubricating bushing (13) is installed at the bottom of the side beam of the bracket (18). A crank (14) is inserted into the self-lubricating bushing (13) and connected to the winch (9). A pulley (2) is installed at the bottom of the pulley fixing plate (1) and installed on the top of the bracket (18). The lifting eye bolt (6) passes through a spring (4) and is fixed with a nut (5). A steel cable (3) is inserted through the top round hole of the lifting eye bolt (6). One end of the steel cable (3) passes through the pulley (2) and is connected to the winch (9).
[0007] It provides a convenient handling mode that can be pushed forward without the need for other auxiliary equipment such as forklifts or cranes.
[0008] Replaceable design: The winch mounting base has 12 pre-drilled screw holes for installing the winch. Different hole positions correspond to winches of different weights. Replacing with a larger winch can increase the load-bearing capacity of the manipulator.
[0009] Shock-absorbing spring structure: By inserting springs into the eye bolts, vibrations generated during winch operation are absorbed, as well as tension generated when the steel cable is under load. Attached image description:
[0010] Figure 1 This is a schematic diagram of the structure of the manipulator for winch lifting of this utility model.

[0012] Overall structural composition: The bottom of the bracket (18) is equipped with two load-bearing wheels (15) and two universal wheels (12). The bottom of the bracket (18) is equipped with a winch fixing seat (10) with 12 mounting holes (101). The winch (9) is installed above the fixing seat (10). The bottom of the side beam of the bracket (18) is equipped with a self-lubricating bushing (13). The crank (14) is inserted into the self-lubricating bushing (13) and connected to the winch (9). The bottom of the pulley fixing plate (1) is equipped with a pulley (2) and installed on the top of the bracket (18). The spring (4) is installed on the eye bolt (6) and the washer (7) is installed at its bottom. Then the nut (5) is screwed in. The top round hole of the eye bolt (6) is inserted into the steel cable (3). One end of the steel cable (3) passes through the pulley (2) and is connected to the winch (9). The crank (14) is detachable and has a hollow structure inside. The end connected to the winch (9) is designed as a square key (11).
[0013] Workflow: Lifting control: After connecting the crank (14) through the self-lubricating bushing (13) to the winch (9), rotating it clockwise will raise the load, and rotating it counterclockwise will lower the load. Shock absorption and buffering: The vibration generated during operation is absorbed by the spring (4) structure. Moving and transporting: After releasing the brake of the caster wheel (12), the whole machine can be easily pushed to the target position and then locked.
[0014] Typical application examples: The manipulator structure of semiconductor testing equipment, especially the test head of ATE testing machines.
[0015] This utility model achieves labor-saving manual drive and self-locking through a winch to meet diverse testing requirements, and has outstanding advantages such as simple structure and safety and reliability.
