Description

Technical Field

[0001] This application relates to the field of gear inspection technology, and in particular to a quick-change worktable. Background Technology

[0002] In automated gear processing and inspection production lines, robotic arms are widely used for handling, loading and unloading, and positioning of gear workpieces between various processes. For gripping the gear body, pneumatic or servo grippers are often used to achieve reliable positioning and handling by clamping the outer circle or inner hole of the gear. On the other hand, for the material trays that carry the gears, in order to avoid damage or positioning misalignment caused by direct contact between the grippers and the material trays, vacuum suction cups are often used for adsorption-type picking and stacking.

[0003] In actual production, robotic arms need to frequently switch between two operating modes: gripping gears and adsorbing material trays. In existing technologies, most production lines use manual replacement of grippers or suction cups. That is, when changing processes, operators stop the machine and use tools such as wrenches to disassemble and assemble the end effector, and then move the corresponding end effector to install it on the robotic arm. This results in long downtime, is labor-intensive, and affects efficiency. Summary of the Invention

[0004] This application aims to at least partially address one of the aforementioned technical problems in the prior art. To this end, embodiments of this application provide a quick-change worktable, avoiding prolonged downtime caused by manual handling of grippers and suction cups, thereby improving efficiency.

[0005] A quick-change worktable, comprising:

[0006] A platform, the platform including a support platform, the support platform having a suction cup placement area and a gripper placement area, the suction cup placement area of ​​the support platform having at least two first positioning holes arranged side by side at intervals;

[0007] A suction cup positioning seat is installed in the suction cup placement area of ​​the support platform. The suction cup positioning seat is provided with a second positioning hole. The number of the second positioning holes is the same as the number of the first positioning holes, and the second positioning holes are aligned with the first positioning holes.

[0008] A gear gripper positioning device is installed in the gripper placement area of ​​the support platform. The gear gripper positioning device is provided with two spaced-apart first slots and second slots.

[0009] In an optional or preferred embodiment, the platform further includes a frame, on which the support platform is mounted.

[0010] In an optional or preferred embodiment, fixing plates are installed on both sides of the bottom of the frame, and the fixing plates are provided with bolt holes for mounting bolts.

[0011] In an optional or preferred embodiment, a cover plate is provided on the support platform, and the cover plate is provided with a third positioning hole corresponding to each of the first positioning holes. The suction cup positioning seat is installed on the cover plate, and the first positioning hole, the second positioning hole and the third positioning hole are aligned.

[0012] In an optional or preferred embodiment, a guide sleeve is provided in the first positioning hole.

[0013] In an optional or preferred embodiment, the gripper positioning device includes a first support plate and a second support plate, which are installed on the cover plate in parallel and spaced apart. A first slot is disposed on the first support plate, and a second slot is disposed on the second support plate. The depth of the first slot is greater than that of the second slot.

[0014] In an optional or preferred embodiment, the gripper positioning device includes a first side plate and a second side plate, the first side plate and the second side plate being respectively disposed on both sides of the first support plate and the second support plate.

[0015] In an optional or preferred embodiment, the gripper positioning device includes a base plate connected to the cover plate, and the first support plate, the second support plate, the first side plate, and the second side plate are all fixed on the base plate.

[0016] In an optional or preferred embodiment, a first photoelectric sensor is provided in the middle of the cover plate to sense whether there is a suction cup on the suction cup positioning seat.

[0017] In an optional or preferred embodiment, a second photoelectric sensor is provided inside the gripper positioning device to sense whether there is a gripper on the gripper positioning device.

[0018] Based on the above technical solution, the embodiments of this application have at least the following beneficial effects: By integrating the suction cup positioning seat and the gear gripper positioning device onto the same platform, this application achieves the positioning and placement of two different types of end effectors on the same worktable. During gear inspection, the robot arm can switch between the gripper and the suction cup on this quick-change worktable. Compared with the prior art, which requires stopping the machine and manually moving the gripper and suction cup over for replacement, this application directly sets up a dedicated worktable for placing the gripper and suction cup. During replacement, the robot arm only needs to move to the worktable, and then the replacement can be performed. Therefore, the quick-change worktable provided in this embodiment significantly shortens the replacement time, avoids long downtime caused by manual handling of the gripper and suction cup, and improves production efficiency.

[0032] In automated gear processing and inspection production lines, robotic arms are widely used for handling, loading and unloading, and positioning of gear workpieces between various processes. For gripping the gear body, pneumatic or servo grippers are often used to achieve reliable positioning and handling by clamping the outer circle or inner hole of the gear. On the other hand, for the material trays that carry the gears, in order to avoid damage or positioning misalignment caused by direct contact between the grippers and the material trays, vacuum suction cups are often used for adsorption-type picking and stacking.

[0033] In actual production, robotic arms need to frequently switch between two operating modes: gripping gears and adsorbing material trays. In existing technologies, most production lines use manual replacement of grippers or suction cups. That is, when changing processes, operators stop the machine and use tools such as wrenches to disassemble and assemble the end effector, and then move the corresponding end effector to install it on the robotic arm. This results in long downtime, is labor-intensive, and affects efficiency.

[0034] Reference Figures 1 to 4 This application provides a quick-change worktable, which includes a platform 100, a suction cup positioning seat 200, and a gear gripper positioning device 300. The platform 100 includes a support platform 110. The support platform 110 has a suction cup placement area and a gripper placement area. The suction cup placement area of ​​the support platform 110 is provided with at least two first positioning holes 111 arranged side by side at intervals. In a specific embodiment, the number of first positioning holes 111 is two, and the two first positioning holes 111 are spaced apart along the length direction of the support platform 110.

[0035] A suction cup positioning base 200 is installed in the suction cup placement area of ​​the support platform 110. The suction cup positioning base 200 has second positioning holes 210. The number of second positioning holes 210 is the same as the number of first positioning holes 111, and the second positioning holes 210 and first positioning holes 111 are aligned one-to-one in the installed state. In this embodiment, the suction cup positioning base 200 is generally a rectangular plate structure with two second positioning holes 210 spaced apart along its length, and mounting holes at its four corners. During installation, the suction cup positioning base 200 is fixed by positioning screws passing through the mounting holes. After the suction cup 500 is placed on the suction cup positioning base 200, the positioning pin at the bottom of the suction cup 500 will embed into the aligned first positioning holes 111 and second positioning holes 210, achieving positioning.

[0036] In some examples, a guide sleeve is provided in the first positioning hole 111. By providing a guide sleeve, wear on the first positioning hole 111 on the support platform 110 body can be avoided during frequent installation and disassembly, thereby extending the service life of the platform 100.

[0037] The gear gripper positioning device 300 is mounted on the gripper placement area of ​​the support platform 110. The gear gripper positioning device 300 has a first slot 311 and a second slot 321 spaced apart, which are used to accommodate and position two annular grooves on the gripper 600. Both the first slot 311 and the second slot 321 are upward-facing open slot structures, and their inner wall contours and dimensions match the annular groove structure on the gripper 600. The first slot 311 and the second slot 321 provide support and limit for the gripper 600, ensuring that the gripper 600 remains stable when placed on the gear gripper positioning device 300.

[0038] This application integrates the suction cup positioning seat and the gear gripper positioning device onto the same platform, enabling the positioning and placement of two different types of end effectors on the same worktable. During gear inspection, the robot arm can switch between the gripper 600 and the suction cup 500 on this quick-change worktable. Compared to the prior art, which requires stopping the machine and manually moving the gripper 600 and suction cup 500 for replacement, this application directly sets up a dedicated worktable for the gripper 600 and suction cup 500. During replacement, the robot arm simply moves to the worktable, and the replacement can be performed. Therefore, the quick-change worktable provided in this embodiment significantly shortens the replacement time, avoids prolonged downtime caused by manual handling of the gripper 600 and suction cup 500, and improves production efficiency.

[0039] In some embodiments, the platform 100 further includes a frame 120. A support platform 110 is mounted on the frame 120. Specifically, the frame 120 is welded from multiple profiles to form a frame structure with sufficient rigidity and strength.

[0040] Furthermore, mounting plates 121 are installed on both sides of the bottom of the frame 120. The mounting plates 121 are provided with bolt holes for mounting bolts. During installation, the frame 120 is fixed to the ground by passing expansion bolts through the bolt holes, so that the quick-change worktable can be stably installed next to the robot arm.

[0041] In some embodiments, a cover plate 130 is provided on the support platform 110. The cover plate 130 serves as a covering layer for the support platform 110, protecting its upper surface. The cover plate 130 has third positioning holes corresponding to each of the first positioning holes 111. After the cover plate 130 is placed on the support platform 110, the third positioning holes are aligned with the first positioning holes 111. A suction cup positioning seat 200 is mounted on the cover plate 130, with the first positioning holes 111, the second positioning holes 210, and the third positioning holes aligned.

[0042] In some embodiments, the gear gripper positioning device 300 includes a first support plate 310 and a second support plate 320. The first support plate 310 and the second support plate 320 are installed on the cover plate 130 in parallel and spaced apart. Specifically, both the first support plate 310 and the second support plate 320 extend vertically and are spaced apart along the width direction of the support platform 110. A first slot 311 is provided on the first support plate 310, and a second slot 321 is provided on the second support plate 320. The depth of the first slot 311 is greater than the depth of the second slot 321 to accommodate two annular grooves of different heights on the gripper 600.

[0043] Furthermore, the gear gripper positioning device 300 also includes a first side plate 330 and a second side plate 340. The first side plate 330 and the second side plate 340 are respectively disposed on both sides of the first support plate 310 and the second support plate 320. Specifically, the first side plate 330 and the second side plate 340 are respectively disposed at both ends of the first support plate 310 and the second support plate 320 along the length direction of the support platform 110, thereby forming a rectangular frame structure together with the first support plate 310 and the second support plate 320. The first side plate 330 and the second side plate 340 provide structural support for the entire gear gripper positioning device 300, enhancing the structural strength of the entire gear gripper positioning device 300.

[0044] Furthermore, the gear gripper positioning device 300 also includes a base plate 350. The base plate 350 is connected to the cover plate 130. The first support plate 310, the second support plate 320, the first side plate 330, and the second side plate 340 are all fixed on the base plate 350.

[0045] In some embodiments, a first photoelectric sensor 400 is disposed in the middle of the cover plate 130. The first photoelectric sensor 400 is used to sense whether there is a suction cup 500 on the suction cup positioning seat 200. When the suction cup 500 is correctly placed on the suction cup positioning seat 200, the suction cup 500 will block the light path of the first photoelectric sensor 400, and the first photoelectric sensor 400 will emit a signal indicating the presence of an object; when the suction cup 500 is removed by the robotic arm, the light path is unblocked, and the first photoelectric sensor 400 will emit a signal indicating the absence of an object.

[0046] In some embodiments, a second photoelectric sensor is provided inside the gear gripper positioning device 300. The second photoelectric sensor is used to sense whether there is a gripper 600 on the gear gripper positioning device 300. The detection end of the second photoelectric sensor faces upward. When the gripper 600 is correctly placed on the gear gripper positioning device 300, the main body of the gripper 600 will be located between the two first slots 311 and the second slot 321, blocking the light path of the second photoelectric sensor, and the sensor will emit a signal indicating the presence of an object; when the gripper 600 is removed, the second photoelectric sensor will emit a signal indicating the absence of an object.

[0047] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
