[0001] This utility model relates to the field of low-voltage switchgear manufacturing technology, and in particular to a workstation device. Background Technology

[0002] In the production process of low-voltage switchgear, the installation and wiring of front-of-cabinet components refers to the key process of installing various electrical components and connecting wires in the front area of ​​the cabinet.

[0003] In existing technologies, assembly lines operate on one side only, requiring workers to cross the production line for installation, resulting in low production efficiency and safety hazards; furthermore, during the production process, additional equipment is needed for weighing to detect weight deviations, which takes up a lot of space.

[0004] In other words, existing production lines have disadvantages such as low production efficiency and safety hazards due to workers crossing the production line to install equipment, and the need for additional equipment for weighing, which results in a large space occupation. Utility Model Content

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] like Figures 1 to 5 As shown, this embodiment provides a workstation device, which includes a main worktable 10, a lifting mechanism 20, and a rotating mechanism 30 or a weighing mechanism 40. The main worktable 10 has a main platform 101 for carrying workpieces. The lifting mechanism 20 is disposed within the main worktable 10. One of the rotating mechanism 30 and the weighing mechanism 40 is detachably connected to the lifting mechanism 20. The lifting mechanism 20 is used to drive the rotating mechanism 30 or the weighing mechanism 40 to rise or fall, so that the rotating mechanism 30 or the weighing mechanism 40 is flush with the main platform 101 to carry the workpiece, or so that the rotating mechanism 30 or the weighing mechanism 40 is higher than the main platform 101. The rotating mechanism 30 is used to carry the workpiece and drive the workpiece to rotate, and the weighing mechanism 40 is used to carry the workpiece and weigh it. The workpiece includes, but is not limited to, a switch cabinet.

[0044] The main worktable 10 carries the workpiece. A lifting mechanism 20 is installed within the main worktable 10. The lifting mechanism 20 drives the rotating mechanism 30 to rise. When the rotating mechanism 30 is higher than the main table surface 101, it lifts the workpiece, causing it to detach from the main table surface 101. Then, the rotating mechanism 30 rotates the workpiece. After the workpiece rotates, the lifting mechanism 20 drives the rotating mechanism 30 to descend until it is flush with the main table surface 101, allowing the workpiece to be placed back on the main table surface 101. This completes the adjustment of the workpiece angle, replacing cross-line operations, improving production efficiency and reducing safety risks. Depending on actual needs, the rotating mechanism 30 can be removed from the lifting mechanism 20 and replaced with a weighing mechanism 40. The lifting mechanism 20 drives the weighing mechanism 40 to rise. When the weighing mechanism 40 is higher than the main table surface 101, it lifts the workpiece. After the workpiece detaches from the main table surface 101, the weighing mechanism 40 weighs the workpiece, helping to save space and make the layout more compact.

[0045] In this embodiment, the X direction is the width direction of the main workbench 10, the Y direction is the length direction of the main workbench 10, and the Z direction is the height direction of the main workbench 10. The main workbench 10 has a main table surface 101 on one side along the Z direction and a bracket 102 on the other side for supporting it on the ground. The other side of the main workbench 10 also has an installation space for accommodating other parts. The main workbench 10 is rectangular, and a bracket 102 is provided at each of the four corners of the main workbench 10. The bracket 102 can be fixed to the main workbench 10 by bolts or by welding or other methods.

[0046] See Figure 1 , Figure 2 and Figure 5 Furthermore, the workstation device also includes a conveying drive 51, a transmission structure 52, and multiple transmission rollers 53. The transmission rollers 53 are rotatably embedded in the main table surface 101. The conveying drive 51 drives all the transmission rollers 53 to rotate synchronously through the transmission structure 52. The rotation of the transmission rollers 53 is used to roll and convey the workpiece. The axis of the transmission rollers 53 is parallel and perpendicular to the workpiece conveying direction, so as to convey the workpiece from the starting position of the main table surface 101 to a preset position corresponding to the rotating mechanism 30 or the weighing mechanism 40.

[0047] By embedding transmission rollers 53 on the main table surface 101 of the main worktable 10, and using the transmission drive component 51 to drive all transmission rollers 53 to rotate synchronously through the transmission structure 52, the workpiece is rolled and conveyed from the starting position of the main table surface 101 to a preset position corresponding to the rotating mechanism 30 or the weighing mechanism 40. This allows the rotating mechanism 30 or the weighing mechanism 40 to bear the workpiece at the preset position, preparing for subsequent rotation or weighing. There is no need for workers to transfer the workpiece, which helps to reduce labor intensity and improve work efficiency.

[0048] In this embodiment, the preset position corresponds to the position of the rotating mechanism 30 or the weighing mechanism 40. That is, when the workpiece is in the preset position, the workpiece is at least partially supported by the rotating mechanism 30 or the weighing mechanism 40. The transmission rollers 53 are arranged in two rows along the X direction, and each row includes multiple transmission rollers 53 arranged along the Y direction. The transmission drive 51 and the transmission structure 52 are arranged on the main worktable 10 and located in the installation space of the main worktable 10.

[0049] Specifically, the transmission structure 52 includes a transmission rod 520, which is rotatably mounted on the main worktable 10. The transmission drive component 51 is chain-driven connected to the transmission rod 520, and both ends of the transmission rod 520 are chain-driven connected to two rows of transmission rollers 53 respectively.

[0050] The transmission structure 52 also includes a first sprocket 521 and a second sprocket 522; there are two first sprockets 521, and one first sprocket 521 is connected to each end of the output shaft of the transmission drive 51; there are four second sprockets 522, the transmission rod 520 extends along the X direction, and the four second sprockets 522 are fixed at intervals along the X direction on the transmission rod 520, of which two second sprockets 522 are located at both ends of the transmission rod 520, and the other two second sprockets 522 are located in the middle of the transmission rod 520.

[0051] In this embodiment, the transmission drive 51 is a motor; each transmission roller 53 is connected to a transmission sprocket 531. The output shaft of the transmission drive 51 drives the first sprocket 521 to rotate and drives the second sprocket 522 located in the middle of the transmission rod 520 to rotate through the first chain 526, thereby driving the transmission rod 520 to rotate. The rotation of the transmission rod 520 drives the second sprocket 522 located at the end of the transmission rod 520 to rotate, thereby driving the transmission sprocket 531 to rotate through the second chain 527. Since there are two second chains 527 to drive the two rows of transmission sprockets 531 to rotate, the synchronous rotation of all transmission sprockets 531 is achieved.

[0052] Optionally, the transmission structure 52 also includes a third sprocket 523. The third sprocket 523 is provided in two sets, and each set is provided with two third sprockets 523. The third sprocket 523 is rotatably mounted on the main worktable 10 to adjust the tension of the second chain 527.

[0053] Optionally, the transmission structure 52 further includes a fourth sprocket 524 and a fifth sprocket 525, both of which are rotatably mounted on the main worktable 10. The fourth sprocket 524 and the fifth sprocket 525 are located near the last transmission roller 53 in each row along the Y direction. In this embodiment, two fourth sprockets 524 and two fifth sprockets 525 are provided to correspond to the two rows of transmission rollers 53. By providing the fourth sprockets 524 and the fifth sprockets 525, the angle at which the second chain 527 enters and exits from the transmission sprocket 531 is not too small, preventing the second chain 527 from tilting up in the middle of the transmission rollers 53.

[0054] See Figures 1 to 4 To limit the direction of workpiece movement, the worktable device also includes two rows of rolling bearings 61. All drive rollers 53 are located between the two rows of rolling bearings 61. Each row of rolling bearings 61 is spaced apart along the workpiece conveying direction. The rolling bearings 61 are rotatably protruding from the main table surface 101. The two rows of rolling bearings 61 are used to limit the workpiece from both sides. By setting two rows of rolling bearings 61 and placing all drive rollers 53 between the two rows of rolling bearings 61, the workpiece is conveyed by the drive rollers 53 and limited by the rolling bearings 61, thereby limiting the conveying direction of the workpiece and ensuring that the workpiece will not deviate or fall during the conveying process.

[0055] In this embodiment, the rolling bearings 61 are arranged in two rows along the X direction, and each row includes multiple rolling bearings 61 spaced apart along the Y direction; the two rows of transmission rollers 53 are located between the two rows of rolling bearings 61, and the Y direction is the workpiece conveying direction.

[0056] Furthermore, the workstation device also includes a fixed limiting member 62 and a telescopic limiting member 63. The fixed limiting member 62 and the telescopic limiting member 63 are respectively disposed on both sides of the rotating mechanism 30 or the weighing mechanism 40 along the workpiece conveying direction. The telescopic limiting member 63 is located near the starting position, and the fixed limiting member 62 protrudes from the main table surface 101. The position between the fixed limiting member 62 and the telescopic limiting member 63 is a preset position. The telescopic limiting member 63 retracts to allow the workpiece to pass through, and the telescopic limiting member 63 extends and cooperates with the fixed limiting member 62 to limit the workpiece to the preset position.

[0057] By setting a fixed limiter 62 and a telescopic limiter 63 in the workpiece conveying direction, and setting the position between the fixed limiter 62 and the telescopic limiter 63 as the preset position, that is, the fixed limiter 62 and the telescopic limiter 63 are respectively located on both sides of the rotating mechanism 30 or the weighing mechanism 40, and the telescopic limiter 63 is set near the starting position, the workpiece is conveyed from the starting position. When the telescopic limiter 63 retracts, the workpiece can pass through and move towards the fixed limiter 62. When the end of the workpiece abuts against the fixed limiter 62, the telescopic limiter 63 extends after the workpiece is in place. The extended telescopic limiter 63 and the fixed limiter 62 work together to limit the workpiece in the preset position and prevent the workpiece from shifting.

[0058] In this embodiment, one end of the main table 101 along the Y direction is the starting position, the telescopic limiter 63 is located near the starting position, and the fixed limiter 62 is located at the other end of the main table 101 along the Y direction. When the workpiece is conveyed to the preset position, one end of the workpiece along the Y direction contacts the fixed limiter 62 and the other end contacts the telescopic limiter 63 in the extended state.

[0059] Optionally, the workstation device also includes position sensors, including a feed detection sensor and a position sensor. The feed detection sensor is located near the starting position for feed detection, and the position sensor is located near the fixed limit member 62 for position detection. The workstation device also includes a control system, which is integrated into the main control box of the production line and controlled by a PLC program, such as controlling the start of the lifting mechanism 20 and the rotating mechanism 30.

[0060] Please refer to Figure 6 The telescopic limiter 63 includes a housing 631, a guide rod 632, and an elastic element 633. The housing 631 is fixed to the main worktable 10. The guide rod 632 slides through the housing 631. One end of the guide rod 632 is connected to the bottom surface of the housing 631 through the elastic element 633. The other end of the guide rod 632 is selectively protruded from the main worktable 101.

[0061] Optionally, the telescopic limiter 63 also includes a roller 634, which is rotatably mounted on the other end of the guide rod 632. The housing 631 has a receiving groove for accommodating the roller 634. By providing the roller 634 at the end of the guide rod 632, the roller 634 can stop the workpiece, thus providing a certain buffering effect and preventing damage to the workpiece.

[0062] In this embodiment, the guide rod 632 extends along the Z direction; the elastic element 633 is a spring; and the telescopic limiter 63 is a pneumatic limiter. When the workpiece reaches the vicinity of the telescopic limiter 63, the air valve opens, and the guide rod 632 moves downward along the Z direction under the action of compressed air (i.e., in a retracted state), thereby allowing the workpiece to pass smoothly. After the workpiece passes, the air valve closes, and under the action of the elastic element 633, the guide rod 632 rises along the Z direction (i.e., in an extended state), thereby blocking the workpiece.

[0063] It is understandable that in this embodiment, since the main table 101 is equipped with a transmission roller 53, the height of the roller 634 at the other end of the guide rod 632 must be higher than the height of the transmission roller 53 to achieve a limiting effect on the workpiece. Similarly, when the lifting mechanism 20 drives the rotating mechanism 30 or the weighing mechanism 40 to rise or fall, the rotating mechanism 30 or the weighing mechanism 40 can only carry the workpiece when it is level with the transmission roller 53, and the workpiece can only be lifted and detached from the transmission roller 53 when it is higher than the height of the transmission roller 53. In other embodiments, if a conveyor belt structure level with the main table 101 is used to transport the workpiece, then the roller 634 at the other end of the guide rod 632 protruding from the main table 101 can achieve a limiting effect, the rotating mechanism 30 or the weighing mechanism 40 level with the main table 101 can carry the workpiece, and the rotating mechanism 30 or the weighing mechanism 40 higher than the main table 101 can detach the workpiece from the main table 101.

[0064] See Figure 2 , Figure 4 and Figure 7 The lifting mechanism 20 includes a base 21, a scissor lift bracket 22, a lifting platform 23, and a lifting drive component 24. The scissor lift bracket 22 and the lifting drive component 24 are positioned between the base 21 and the lifting platform 23. A rotating mechanism 30 is detachably mounted on the lifting platform 23. The lifting drive component 24 drives the lifting platform 23 to move relative to the base 21 and causes the scissor lift bracket 22 to extend and retract. By setting the scissor lift bracket 22 and the lifting drive component 24 between the base 21 and the lifting platform 23, and by having the lifting drive component 24 drive the lifting platform 23 to rise and fall and cause the scissor lift bracket 22 to extend and retract, the thrust of the lifting drive component 24 is evenly distributed to multiple support points, dispersing load stress, reducing single-point stress, and improving movement stability.

[0065] In this embodiment, the lifting mechanism 20 is located in the installation space of the main workbench 10 and is positioned in the middle of the main workbench 10; the lifting drive component 24 is a cylinder; the base 21 can be fixed to the main workbench 10 or directly supported on the ground.

[0066] See Figures 7 to 9 The scissor lift support 22 includes a scissor assembly 220, which includes a first arm 221 and a second arm 222. The first arm 221 and the second arm 222 cross in the middle and are rotatably connected by a central shaft 223. The first end of the first arm 221 is slidably hinged to the base 21, and the second end of the first arm 221 is hinged to the lifting platform 23. The first end of the second arm 222 is hinged to the base 21, and the second end of the second arm 222 is slidably hinged to the lifting platform 23. By setting one end of the arm to be hinged and the other end to be slidably hinged, a limited distance of sliding can be achieved during the lifting process, while the rest are rotary joints. This design can suppress possible rotation or tilting tendencies during the lifting process, ensuring the stability and reliability of the lifting mechanism 20.

[0067] In this embodiment, the first end of the first support arm 221 and the second end of the second support arm 222 are located on one side of the transverse direction of the central axis 223, and the second end of the first support arm 221 and the first end of the second support arm 222 are located on the other side of the transverse direction of the central axis 223. Two sets of scissor lift assemblies 220 are spaced apart along the X direction, and the lifting drive member 24 is located between the two sets of scissor lift assemblies 220. The hinged end (e.g., the first end of the first support arm 221) can provide a stable fulcrum, and the sliding hinged end (e.g., the second end of the first support arm 221) allows dynamic displacement. By setting the sliding hinged end on one side of the transverse direction of the central axis 223 and setting the hinged end on the other side of the transverse direction of the central axis 223, the load distribution can be dispersed to reduce stress concentration, reduce the restriction on the setting position of the lifting drive member 24, and achieve a larger stroke within a limited space.

[0068] Optionally, the scissor lift assembly 220 further includes a first auxiliary component 224. Guide rails 25 are provided on both the base 21 and the lifting platform 23. The first end of the first support arm 221 and the second end of the second support arm 222 are both hinged to the first auxiliary component 224. A slider 26 is fixed on the first auxiliary component 224, and the slider 26 slides in engagement with the corresponding guide rail 25. By setting the first auxiliary component 224 and the guide rail 25, and utilizing the hinged connection between the first auxiliary component 224 and the corresponding support arm and the fixed connection with the slider 26, the slider 26 slides in engagement with the guide rail 25, thereby achieving a sliding hinge. This not only restricts the direction of movement of the slider 26 but also limits the distance of movement of the slider 26.

[0069] In this embodiment, the slider 26 is provided with an oil nozzle 261, through which lubricating oil can be injected into the slider 26 to ensure that the slider 26 and the guide rail 25 can slide normally; the slider 26 is provided with through holes at the four corners, and the first auxiliary component 224 can be fixed to the slider 26 at the through holes with bolts.

[0070] Optionally, the scissor lift assembly 220 further includes a second auxiliary component 225. The second end of the first arm 221 and the first end of the second arm 222 are both hinged to a second auxiliary component 225 and fixed to the corresponding base 21 or lifting platform 23 via the second auxiliary component 225. In this embodiment, the first auxiliary component 224 and the second auxiliary component 225 have the same structure. Compared to the arm being directly hinged to the base 21 or lifting platform 23, the second auxiliary component 225 serves as a transition component. The arm is hinged to the corresponding base 21 or lifting platform 23 via the second auxiliary component 225, which can transfer concentrated stress in the arm, preventing deformation due to localized stress concentration and ensuring better load-bearing capacity. Furthermore, the second auxiliary component 225 can be fixed to the base 21 or lifting platform 23 with bolts, allowing for individual disassembly and replacement for easy maintenance.

[0071] Optionally, the base 21 is also provided with a support frame 27, which is used to support the lifting platform 23 at its lowest position. In this embodiment, the support frame 27 is I-shaped and is fixed to the base 21 by bolts; the support frame 27 is located near the central axis 223, and the guide rail 25 is located on one side of the support frame 27 along the Y direction.

[0072] See Figure 1 and Figure 4 When the lifting platform 23 moves upward along the Z-direction, the slider 26 moves towards the end of the guide rail 25 closest to the support frame 27 (i.e., to the right). When the slider 26 is at the rightmost end of the guide rail 25, the lifting platform 23 is at its highest position. When the lifting platform 23 moves downward along the Z-direction, the slider 26 moves towards the end of the guide rail 25 furthest from the support frame 27 (i.e., to the left). When the slider 26 is at the leftmost end of the guide rail 25, the lifting platform 23 is at its lowest position, and at this time, the support frame 27 provides support for the lifting platform 23. It is understood that the limit of the guide rail 25 is related to other mechanisms, and the maximum height of the lifting platform 23 is limited by the lifting drive component 24 and the main worktable 10. The guide rail 25 of appropriate length can be designed according to actual needs.

[0073] See Figure 2 , Figure 10 and Figure 11Furthermore, the rotating mechanism 30 includes a rotating support 31, a rotating table 32, and a rotating drive 33. The rotating support 31 and the rotating drive 33 are detachably connected to the lifting mechanism 20. The rotating table 32 is connected to the rotating support 31. The main worktable 10 has a receiving space 103 on one side of the main table surface 101. The receiving space 103 is used to receive the rotating table 32. The rotating drive 33 drives the rotating table 32 to rotate relative to the lifting mechanism 20 through the rotating support 31.

[0074] In this embodiment, a rectangular opening is provided on one side of the main platform 101, which communicates with the installation space of the main workbench 10 and serves as a receiving space 103. A lifting platform 23 is located within the installation space. A rotating platform 32 is detachably mounted above the lifting platform 23 via a rotating support 31, and is positioned in the middle of the lifting platform 23. A rotating drive 33 is bolted to the bottom of the lifting platform 23 and partially passes through the lifting platform 23, connecting to the rotating support 31 for transmission, so that the lifting platform 23 drives the rotating drive 33 to rise and fall. The size of the lifting platform 23 is larger than the size of the rotating platform 32. Using the rotating support 31, the rotating platform 32 is detachably mounted on the lifting mechanism 20 and can rotate relative to the lifting mechanism 20, providing good load-bearing capacity and helping to ensure stable operation.

[0075] Optionally, the rotating support 31 includes an inner fixed ring 311, an outer gear ring 312, and a bearing 313. The inner fixed ring 311 is detachably fixed to the lifting mechanism 20. The outer gear ring 312 is rotatably sleeved on the inner fixed ring 311 through the bearing 313. The rotating table 32 is fixed to the outer gear ring 312. The rotating drive 33 is used to drive the outer gear ring 312 to rotate so as to drive the rotating table 32 to rotate.

[0076] In this embodiment, the external gear ring 312 is fixed to the rotary table 32 by bolts. The lifting platform 23 is provided with multiple first mounting holes 231. The inner fixing ring 311 is fixed to the first mounting holes 231 of the lifting platform 23 by bolts. The inner fixing ring 311 is provided with a fixing threaded hole 314 for the bolts to pass through. The rotary drive component 33 includes a motor (not shown) and a rotating component mounted on the motor. The motor is fixed to the bottom of the lifting platform 23 by bolts. The motor is used to drive the rotating component to rotate. The end of the rotating component passes through the lifting platform 23 and is provided with a gear. When the rotating component rotates, it meshes with the external gear ring 312 through the gear, thereby driving the external gear ring 312 and the rotary table 32 to rotate. By setting the external gear ring 312 and using the motor to drive the rotary table 32 to rotate through gear meshing, the structure is compact, saves space, can operate stably for a long time, and has high transmission efficiency.

[0077] See Figure 3 and Figure 12The weighing mechanism 40 includes a weighing platform 41, on which a weighing sensor is mounted. The weighing platform 41 is detachably mounted on the lifting mechanism 20. The accommodating space 103 on the main worktable 10 is used to accommodate the weighing platform 41. The lifting mechanism 20 drives the weighing mechanism 40 to rise and fall, so that the weighing platform 41 is flush with or higher than the main worktable 101. After removing the rotating mechanism 30, the weighing platform 41 and the weighing sensor can be installed at the middle position of the lifting platform 23, enabling the workstation device to have a weighing function. In this embodiment, the weighing sensor is integrated into the weighing platform 41; the weighing platform 41 is located at the middle position of the lifting platform 23; the lifting platform 23 has multiple second mounting holes 232, and the weighing platform 41 is fixed to the second mounting holes 232 with bolts. In other embodiments, depending on the type of weighing sensor, the weighing sensor can also be mounted outside the weighing platform 41.

[0078] The following is the specific operating procedure for the lifting and rotating of the workstation device:

[0079] This workstation device needs to work in conjunction with an RGV trolley, which transports the workpiece to the workstation. When the feed detection sensor detects the workpiece, the control system immediately activates the conveyor drive 51, which drives multiple transmission rollers 53 to rotate synchronously via chain drive, thus rolling and conveying the workpiece. The telescopic limiter 63 retracts, allowing the workpiece to pass smoothly and move along the Y direction towards the fixed limiter 62. Under the action of the rolling bearing 61, the workpiece will not shift along the X direction. When the product reaches the preset position, the end of the workpiece contacts the fixed limiter 62. After the arrival sensor detects the workpiece's arrival, the control system immediately stops driving the transmission rollers 53. At this time, the telescopic limiter 63 automatically extends, effectively constraining the workpiece's position in the Y direction in conjunction with the fixed limiter 62.

[0080] After completing the task, the operator starts the lifting mechanism 20 using an external control button. The lifting drive 24 drives the lifting platform 23 to rise along the Z direction, smoothly lifting the workpiece and separating it from the main table 101 and the transmission roller 53. When the workpiece reaches a certain height, the lifting drive 24 stops and remains locked. The operator can then control the rotation drive 33 using an external button. The gear of the rotation drive 33 meshes with the external gear ring 312 of the rotation support 31, thereby driving the rotating table 32 and the workpiece to rotate, achieving precise positioning and rotation of the workpiece. For example, the first rotation is 90° clockwise, and a second operation can complete a 180° rotation. After the workpiece completes a 180° rotation, the operator controls the lifting drive 24 to lower the lifting platform 23 along the Z direction back to the origin, placing the workpiece back on the transmission roller 53 on the main table 101. The operator continues the task. After the task is completed, the operator presses a button to notify the control system that the task is complete, and waits for the system to automatically complete the workpiece output and the loading of a new workpiece.

[0081] The following is the specific usage process of the lifting and weighing device on the workstation:

[0082] According to actual needs, the rotating mechanism 30 can be removed and a weighing mechanism 40 installed, so that the workstation device has a weighing function. The workpiece is transported to the workstation device by the RGV trolley. When the feed detection sensor detects the workpiece, the control system immediately starts the conveying drive 51, which drives multiple transmission rollers 53 to rotate synchronously through chain drive, thereby rolling and conveying the workpiece. The telescopic limiter 63 retracts, allowing the workpiece to pass smoothly and move in the Y direction toward the direction close to the fixed limiter 62. Under the action of the rolling bearing 61, the workpiece will not be displaced in the X direction. When the product is conveyed to the preset position, the end of the workpiece contacts the fixed limiter 62. After the arrival sensor detects that the workpiece has arrived, the control system immediately stops driving the transmission rollers 53. At this time, the telescopic limiter 63 automatically extends, and the telescopic limiter 63, together with the fixed limiter 62, effectively constrains the position of the workpiece in the Y direction.

[0083] After the arrival sensor detects the workpiece's arrival, the control system stops the transmission roller 53 and times for 2 seconds. After timing, the lifting drive 24 is activated, bringing the weighing mechanism 40 into direct contact with the workpiece. The workpiece is smoothly lifted and detached from the main table 101 and the transmission roller 53. When the workpiece reaches a certain height, the lifting drive 24 stops and remains locked. The control system times for 5 seconds (after the weighing data stabilizes) before reading and storing the weighing data. The operator controls the lifting drive 24 to lower the lifting platform 23 along the Z-direction back to the origin, placing the workpiece back on the transmission roller 53 on the main table 101, awaiting the next process, or it can be transported to the next process via an RGV trolley, or removed from the production line by the unloading equipment.
