Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor industry testing equipment technology, and in particular to a device for auxiliary support counterweight leveling. Background Technology
[0002] In the semiconductor industry testing process, electric lifting stands are a commonly used test head docking device. During production assembly and customer use, the counterweight box needs to be leveled with the test head, and this needs to be done more than once.
[0003] Traditional methods for balancing the counterweight box and test head of electric lifting supports rely primarily on simple mechanical structures and manual experience. Electric lifting supports are equipped with basic motor-driven lifting structures. The motor is connected to the support arm containing the test head and counterweight box via a transmission device (such as a chain or lead screw) to achieve the lifting action. For balancing, adjustable counterweights are typically placed on the support arm, and balance is attempted by manually adding or removing these weights. A simple level is used for rough assessment of balance, but this method lacks precise monitoring of parameters such as motor power, failing to reflect the actual situation of the counterweight in real time. Furthermore, the level only detects whether the surface is level; it cannot provide clear indications of whether the counterweight box needs to be increased or decreased. Regarding safety, only simple limit switches are typically installed to prevent the test head or counterweight box from exceeding its limits. However, there is a lack of effective real-time monitoring and early warning mechanisms for abnormal situations during operation, such as motor stalling or foreign objects obstructing transmission components. In such cases, the problem is often only discovered by the operator's visual inspection or after the equipment emits abnormal sounds, at which point the equipment may have already been damaged to some extent. Utility Model Content
[0004] The purpose of this invention is to provide a device for leveling an auxiliary support with counterweights, in order to solve the above-mentioned technical problems.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A device for leveling an auxiliary support with counterweight includes a base plate, a driver, a PLC, a motor, a power detector, a tri-color light, a reducer, and a torque limiter. The motor is mounted on one side of the base plate, the reducer is mounted above the motor, the driver is mounted on one side of the reducer, and the PLC is mounted below the motor. The tri-color light and the power detector are mounted at one end of the base plate, and the torque limiter is mounted on the other side of the base plate. The motor is connected to the driver and the reducer, the reducer is connected to the torque limiter, the torque limiter is connected to the power shaft of the auxiliary support, and the PLC is connected to the power detector and the tri-color light.
[0007] Preferably, the system also includes a first power module and a second power module, which are located at both ends of the motor and connected to the inner wall of the base plate. The power detector is connected to the first power module and the second power module, with the first power module connected to the motor and the second power module connected to the driver.
[0008] Preferably, a power plug is also included, which is connected to the power detector via a power cord.
[0009] Preferably, a buzzer is also included, which is located at one end of the base plate and is connected to the PLC.

[0015] As a further preferred embodiment, the base plate also includes a pad, which is provided at one end of the base plate and contacts the inner wall of the outer casing.
[0016] The above technical solution has the following advantages or beneficial effects:
[0017] (1) In this utility model, through the coordinated work of PLC, power detector and three-color light, the operator can quickly determine the direction of adjustment of the counterweight box weight based on the real-time color of the three-color light, whether to increase or decrease the counterweight; compared with the traditional method of roughly judging the balance state by relying only on the level, the balance feedback of this device is more accurate and intuitive; this makes it possible for the operator not to repeatedly try to adjust the counterweight based on experience during production assembly and testing, which greatly saves the debugging time of a single bracket, significantly improves the production assembly speed, and thus improves the overall production efficiency.
[0018] (2) In this utility model, the test head and the counterweight box can be quickly balanced according to the indication of the three-color light, avoiding the lengthy balancing process in the traditional method, greatly shortening the time spent on the balancing link in the client's installation process, helping the client's equipment to be put into use faster, and improving customer satisfaction.
[0019] (3) In this utility model, when the equipment is stuck, interfered or other faults occur, the power change detected by the power detector will cause the PLC to react quickly. It will not only control the three-color light to emit a red or yellow warning signal, but also trigger the buzzer alarm at the same time. This real-time fault warning mechanism can enable the operator to detect the abnormality of the equipment at the first time and take timely measures. It can effectively avoid the situation that the equipment will be further damaged due to the failure to detect the fault in time, reduce the maintenance cost and ensure the normal operation of the equipment.
[0020] (4) In this utility model, the 60V power supply (first power supply module) is dedicated to powering the motor, and the 24V power supply (second power supply module) is dedicated to powering the driver, ensuring that each component can obtain a stable and suitable power supply. This power supply design reduces the risk of equipment failure caused by unstable voltage or uneven power distribution, improves the stability and reliability of the entire device operation, and reduces equipment maintenance costs and downtime.

[0027] Figure 1 This is an exploded schematic diagram of the auxiliary support counterweight leveling device in this utility model; Figure 2 This is a schematic diagram illustrating the usage of the auxiliary support counterweight leveling device in this utility model. Please refer to [link / reference]. Figures 1 to 2 The diagram illustrates a preferred embodiment of an auxiliary support counterweight leveling device, comprising a base plate 1, a driver 4, a PLC 6 (Programmable Logic Controller), a motor 7, a power detector 8, a tri-color light 10, a reducer 14, and a torque limiter 16. The motor 7 is mounted on one side of the base plate 1, the reducer 14 is mounted above the motor 7, the driver 4 is mounted on one side of the reducer 14, and the PLC 6 is mounted below the motor 7. The tri-color light 10 and the power detector 8 are mounted at one end of the base plate 1, and the torque limiter 16 is mounted on the other side of the base plate 1. The motor 7 is connected to the driver 4 and the reducer 14, the reducer 14 is connected to the torque limiter 16, and the torque limiter 16 is connected to the drive shaft of the auxiliary support 20. The PLC 6 is connected to the power detector 8 and the tri-color light 10. In this embodiment, see [reference needed]. Figure 1 As shown, the driver 4, PLC 6, motor 7, power detector 8, and reducer 14 are all mounted on the inner side or inner wall of the base plate 1, while the tri-color lamp 10 is mounted on one end of the base plate 1 and extends out of the base plate 1. The tri-color lamp 10 is located above the power detector 8. The driver 4, PLC 6, power detector 8, tri-color lamp 10, and torque limiter 16 can all be mounted on the base plate 1 with screws or bolts.
[0028] In this embodiment, through the setup of PLC6, tri-color lights 10, and power detector 8, the power detector 8 monitors the operating power of motor 7 in real time and transmits the data to PLC6. PLC6 analyzes and compares the received real-time power signal. When the increasing power is greater than the decreasing power, it controls tri-color lights 10 to light up red; when the decreasing power is greater than the increasing power, it controls tri-color lights 10 to light up yellow; and when the increasing power is equal to the decreasing power, it controls tri-color lights 10 to light up green. By observing the colors reflected by the tri-color lights 10, operators can quickly and intuitively understand the balancing status and determine whether the weight of the counterweight box needs to be increased or decreased, greatly improving balancing efficiency and saving time in production assembly and customer-side balancing.
[0029] Furthermore, as a preferred embodiment, it also includes a first power module 3 and a second power module 5. The first power module 3 and the second power module 5 are located at both ends of the motor 7 and connected to the inner wall of the base plate 1. The power detector 8 is connected to the first power module 3 and the second power module 5. The first power module 3 is connected to the motor 7, and the second power module 5 is connected to the driver 4. In this embodiment, the first power module 3 is a 60V power supply specifically for powering the motor 7, ensuring the stable operation of the motor 7; the second power module 5 is a 24V power supply used to power the driver 4, the tri-color lamp 10, and the PLC 6, ensuring the stable operation of the entire control system. This layered power supply method improves the power supply stability and reliability of each component. In this embodiment, the second power module 5 is also connected to the PLC 6 and the tri-color lamp 10.
[0030] Furthermore, as a preferred embodiment, a power plug 9 is also included, which is connected to the power detector 8 via a power cord. The power plug 9 is used to connect to external mains power to supply power to the power detector 8, which in turn supplies power to the first power module 3 and the second power module 5.
[0031] Furthermore, as a preferred embodiment, a buzzer 19 is also included, which is located at one end of the base plate 1 and connected to the PLC 6. In this embodiment, a housing 17 is also included, with the base plate 1 located inside the housing 17, which is mounted on the side wall of the auxiliary bracket 20. The buzzer 19 penetrates one end of the base plate 1 and extends through the housing 17, reaching the outside of the housing 17. The tri-color lamp 10 also penetrates the housing 17 and extends to the outside of the housing 17. The buzzer 19 is located between the power detector 8 and the tri-color lamp 10. The power detector 8 also extends out of the housing 17, with the buzzer 19, tri-color lamp 10, and power detector 8 all extending out of the housing 17, facilitating signal observation by the operator. In other embodiments, the buzzer 19, tri-color lamp 10, and power detector 8 can also be directly mounted on the outer wall of the housing 17. By connecting the buzzer 19 to the PLC 6, when the tri-color light 10 displays red or yellow, indicating an abnormal balance status or potential equipment malfunction, the PLC 6 simultaneously controls the buzzer 19 to sound an alarm. This not only attracts the operator's attention and allows for timely adjustment of the counterweight, but also quickly issues warning signals when equipment experiences jamming, interference, or malfunctions, reminding the operator to take timely measures to reduce losses caused by operational errors or accidents, thus greatly improving the safety of equipment use.
[0032] The base plate 1 is housed within the outer casing 17, which is mounted to the side wall of the auxiliary support 20 using bolts or screws. A pad 2 is placed at one end of the base plate 1, contacting the inner wall of the outer casing 17 for protection. The motor 7 is connected to the base plate 1 via a motor mounting plate 13, which can be welded to the base plate 1 or bolted to it. The reducer 14 is connected to the base plate 1 via a reducer mounting plate 15, which can also be welded to the base plate 1 or bolted to it. This layout not only makes the device compact and aesthetically pleasing but also facilitates installation and maintenance. It effectively protects the internal circuitry, prevents unauthorized circuit tampering, and improves the overall stability and safety of the equipment.
[0033] Furthermore, as a preferred embodiment, a chain coupling 12 is also included, through which the output shaft of the motor 7 is connected to the reducer 14. In this embodiment, the motor 7 is keyed to the reducer 14 via the chain coupling 12 and locked with a set screw. The output shaft of the reducer 14 is then keyed to the torque limiter 16, and finally the torque limiter 16 is connected to the power shaft of the support body. This power transmission structure ensures effective power transmission while increasing torque through the reducer 14 to meet the needs of different working conditions. Simultaneously, the torque limiter 16 limits the output torque, preventing injury to operators due to excessive output torque caused by unexpected situations, further enhancing the safety of the equipment.
[0034] Furthermore, as a preferred embodiment, it also includes a control button box 18, which is disposed on the side wall of the auxiliary bracket 20 and connected to the driver 4. See also Figure 1 As shown, four buttons are arranged from top to bottom on one side of the button control box: emergency stop button, start button, raise button, and lower button. During the raising operation, the operator must press both the start button and the raise button simultaneously. Upon receiving this signal, the driver 4 sends a control signal to the motor 7, causing the motor 7 to rotate forward. This drives the torque limiter 16 to rotate, which in turn drives the power shaft in the auxiliary support 20, causing the arm in the auxiliary support 20 to rise. Similarly, during the lowering operation, both the start button and the lower button must be pressed simultaneously. The motor 7 rotates in reverse, ultimately driving the arm in the auxiliary support 20 to descend. The emergency stop button can immediately cut off the control signal to the motor 7 in case of an emergency, causing the motor 7 to stop immediately and ensuring the safety of the equipment and personnel.
[0035] In this embodiment, during production assembly or client-side use, the operator adjusts the counterweight of the counterweight box according to the color information displayed by the tri-color light 10. If the tri-color light 10 shows red, it indicates that the counterweight box is relatively light, and the operator needs to increase its weight, which can be achieved by adding counterweight blocks. After adding counterweight blocks, the raising or lowering operation is restarted, and the change in the tri-color light 10 is observed. If the light shows yellow, it indicates that the counterweight box is relatively heavy, and its weight needs to be reduced, for example, by removing some counterweight blocks. By continuously adjusting the counterweight and observing the changes in the tri-color light 10, the balancing operation is completed when the tri-color light 10 shows green. The entire process is fast and intuitive, greatly shortening the balancing time.
[0036] During equipment operation, power detector 8 continuously monitors the power of motor 7. PLC 6 judges the equipment's operating status in real time based on power changes. If abnormalities such as jamming or interference occur, causing a sudden power surge—for example, if motor 7 stalls due to a foreign object blocking its rotation—the power detected by power detector 8 will instantly and significantly increase. Upon receiving this abnormal power signal, PLC 6 immediately controls the tri-color indicator 10 to emit a red or yellow warning signal according to preset judgment logic, and simultaneously triggers the buzzer 19 to sound an alarm. When the operator hears the alarm and sees the warning light, they can quickly press the emergency stop button to stop the equipment, check and troubleshoot the fault, effectively preventing further losses caused by equipment failure and ensuring the safety of equipment and personnel.
[0037] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
