Description

Technical Field

[0001] This invention relates to the field of auxiliary tooling, specifically a labor-saving bending auxiliary tooling. Background Technology

[0002] A bending machine is a machine that can bend workpieces. It bends the workpiece between the pressure plate and the base to make the workpiece meet the preset bending requirements. The workpiece here generally refers to a thin plate. During the bending process, the operator puts the thin plate into the bending opening of the bending machine, and the pressure plate presses down to bend the thin plate. Although it involves bending thin plates, there are cases where the processed thin plates are large, such as the thin plates of voltage cabinets. Large thin plates require multiple people to lift them, and the pressure plate is pressed down slowly. Workers need to maintain the lifting posture, which requires a lot of manpower. Therefore, there is an urgent need for a labor-saving bending auxiliary tool that can assist workers in bending, making it more labor-saving and reducing the consumption of human resources. Summary of the Invention

[0003] The present invention aims to provide a labor-saving bending auxiliary tool that can assist workers in bending, making it more labor-saving and reducing the consumption of human resources.

[0004] This invention provides the following basic solution: a labor-saving bending auxiliary tooling, comprising: a control module, a lifting support module, and a clamping module; Both the lifting support module and the clamping module are electrically connected to the control module; The control module is used to control the lifting support module to lift and lower, and to control the clamping module to clamp and rotate. The lifting support module is located on one side of the bending opening of the bending machine and includes: a base and a support plate; The base is equipped with several electric lifting rods, and the top of each electric lifting rod is rotatably connected to the four corners of the bottom surface of the support plate. The clamping module includes: robotic arms; robotic arms are installed on both sides of the support plate; The control module includes: a controller and control switches; The control switches, electric lifting rod, and robotic arm are all electrically connected to the controller. The control switch is used to input the lifting signal of any electric lifting boom and the action signal of any robotic arm, and send them to the controller; The controller is used to control the raising and lowering of the corresponding electric lifting rod based on the lifting signal; Used to control the corresponding robotic arm to perform actions based on motion signals.

[0005] Beneficial effects of the basic solution: This solution is installed on one side of the bending machine. When bending, the workpiece can be placed on the support plate, reducing the time workers spend lifting the workpiece, especially for larger workpieces. Simultaneously, the position of the support plate can be adjusted via a control switch, allowing the workpiece to be pushed into the bending opening of the bending machine. During bending, the control switch inputs a lifting signal for any electric lifting rod, which is sent to the controller. The controller, based on the lifting signal, controls the corresponding electric lifting rod to rise or fall, thus causing the support rod to tilt and maintain its support for the workpiece. The connection between the support plate and the electric lifting rod is a rotatable connection; if the four electric lifting rods rise or fall at different times, the connection will rotate without affecting the lifting. During the bending process, if it is necessary to flip or move the workpiece, the action signal of any robotic arm can be input through the control switch. The controller will then control the corresponding robotic arm to perform the action and flip or move the workpiece according to the action signal. During the bending process described above, this fixture can effectively support, flip, and move the workpiece, effectively assisting workers in bending and making it easier for them. For larger workpieces, it can also appropriately reduce manpower, thereby reducing the consumption of human resources. In summary, this solution can assist workers in bending, saving them effort and reducing the consumption of human resources.

[0006] Furthermore, the bottom of the electric lifting rod is fixedly connected to the top surface of the base, and the top surface of the electric lifting rod is rotatably connected to the bottom surface of the support plate; There shall be no fewer than four electric lifting rods, and the four electric lifting rods shall be rotatably connected to the four corners of the bottom surface of the support plate.

[0007] There should be no fewer than four electric lifting rods, which are connected to the four corners of the bottom surface of the support plate to ensure support for the foundation of the support plate. The number of electric lifting rods can be increased as needed to ensure support.

[0008] Furthermore, the electric lifting rod includes: a first electric lifting rod, a second electric lifting rod, a third electric lifting rod, and a fourth electric lifting rod, which are rotatably connected to the four corners of the bottom surface of the support plate, respectively; the distance between the third electric lifting rod and the fourth electric lifting rod and the bending machine is less than the distance between the first electric lifting rod and the second electric lifting rod and the bending machine.

[0009] Furthermore, the control switch includes: an electric lifting rod switch and a robotic arm switch; The electric lifting pole switch includes: an up switch, a down switch, an outer up switch, an outer down switch, an inner up switch, and an inner down switch; Robotic arm switches include: gripping switches, release switches, clockwise rotation switches, and counterclockwise rotation switches.

[0010] Different control switches can perform different controls, facilitating the precise operation of this tooling.

[0011] Furthermore, by triggering the rise switch once, a rise signal is input to control the rise of all electric lifting rods; triggering it again inputs a stop signal. The controller controls all electric lifting rods to rise according to the rise signal and controls them to stop rising according to the stop signal. By triggering the descent switch once, a descent signal is input to control the descent of all electric lifting masts. A stop signal is input upon triggering the switch again. The controller controls all electric lifting masts to descend based on the descent signal and stops descent based on the stop signal. By triggering the outer rise switch once, an outer rise signal is input to control the rise of the first and second electric lifting rods on the outside. When triggered again, a stop signal is input. The controller controls the first and second electric lifting rods on the outside to rise according to the outer rise signal, and controls the electric lifting rods to stop rising according to the stop signal. By triggering the outer lowering switch once, an outer lowering signal is input to control the lowering of the first and second electric lifting rods on the outside. Upon triggering again, a stop signal is input. The controller controls the first and second electric lifting rods on the outside to lower according to the outer lowering signal, and controls the electric lifting rods to stop lowering according to the stop signal. By triggering the inner lifting switch once, an inner lifting signal is input to control the third and fourth electric lifting rods to rise. Upon triggering again, a stop signal is input. The controller controls the third and fourth electric lifting rods to rise according to the inner lifting signal, and controls the electric lifting rods to stop rising according to the stop signal. By triggering the inner descent switch once, an inner descent signal is input to control the descent of the third and fourth electric lifting rods. Upon triggering again, a stop signal is input. The controller controls the descent of the third and fourth electric lifting rods based on the inner descent signal, and controls the electric lifting rods to stop descent based on the stop signal.

[0012] By triggering each switch, the corresponding action can be completed to support the workpiece.

[0013] Furthermore, by triggering the clamping switch, a clamping signal is input to the robotic arm; based on the clamping signal, the controller generates robotic arm movement data using machine vision technology and end-effector positioning technology, controls the robotic arm to move to one side of the workpiece, and clamps the workpiece. By triggering the release switch, a release signal is input to the robotic arm; the controller controls the robotic arm to move and release the workpiece according to the release signal, and then returns to the default position. By rotating the switch clockwise once to input a clockwise rotation signal, and triggering it again to input a stop signal, the controller controls the gripping end of the robotic arm to rotate clockwise according to the clockwise rotation signal; and controls the robotic arm to stop rotating according to the stop signal. By rotating the switch counterclockwise once to input a counterclockwise rotation signal, and triggering it again to input a stop signal, the controller controls the gripping end of the robotic arm to rotate counterclockwise according to the counterclockwise rotation signal; and controls the robotic arm to stop rotating according to the stop signal.

[0014] By triggering each switch, the corresponding action can be completed to rotate and move the workpiece.

[0015] Furthermore, it also includes: a detection module; The detection module is electrically connected to the control module and is used to detect the distance information between the support plate and the workpiece, and send it to the control module. The control module is also used to control the lifting support module to lift and lower based on distance information.

[0016] The detection module detects distance information, which enables the control module to control the lifting support module to move up and down based on the distance information, thereby realizing a semi-automated bending process and further reducing the need for workers.

[0017] Furthermore, the detection module includes: several grooves on the top surface of the support plate, including: two grooves in total, one at the midpoint of the line connecting the outer lifting support rod connected to the bottom of the support plate and the other at the midpoint of the line connecting the inner lifting support rod. A distance sensor is installed inside the groove; The distance sensor is electrically connected to the controller to detect the distance between the support plate and the workpiece, and generates distance information to send to the controller. The controller is used to adjust the height of the electric lifting rod on the outer or inner side of the distance sensor corresponding to the distance information that does not conform to the preset distance range, so that the distance information conforms to the preset range.

[0018] The detection module is specifically a distance sensor set in the groove of the support plate. It does not affect the placement of the workpiece. Based on the feedback distance information, it controls the electric lifting rod on the outer or inner side of the distance sensor whose distance information does not conform to the preset distance range to adjust the distance information so that it conforms to the preset range, thereby realizing automatic support adjustment.

[0019] Furthermore, the control switch also includes: a detection switch; By triggering the detection switch once, a start signal is input to the distance sensor in the control detection module to start. A second trigger inputs a stop signal to the distance sensor in the control detection module to stop. The controller controls the distance sensor to start according to the start signal and controls the distance sensor to stop according to the stop signal.

[0020] The detection switch can control the opening and closing of the detection module, allowing the automatic support adjustment to be determined by the worker according to the working conditions.

[0021] Furthermore, the support plate is divided into an outer side plate and an inner side plate; the outer side plate and the inner side plate are connected by a telescopic rod, and the first electric lifting rod and the second electric lifting rod are set on the bottom surface of the outer side plate; the third electric lifting rod and the fourth electric lifting rod are set on the bottom surface of the inner side plate; when the outer side plate or the inner side plate rises or falls individually, the telescopic rod stretches or retracts.

[0022] The support plate is divided into an outer plate and an inner plate, which are connected by a telescopic rod. This increases the height difference range between the electric lifting rods, allowing the support plate to better support the workpiece. Attached Figure Description

[0026] Example 1 The basic implementation examples are as follows: Figure 1 As shown: A labor-saving bending auxiliary tooling for assisting a bending machine in bending workpieces, including: a control module, a lifting support module, and a clamping module; Both the lifting support module and the clamping module are electrically connected to the control module; The control module is used to control the lifting support module to lift and lower, and to control the clamping module to clamp and rotate. The lifting support module is located on one side of the bending opening of the bending machine and includes: a base and a support plate; The base is equipped with several electric lifting rods, the top of which is rotatably connected to the four corners of the bottom surface of the support plate; specifically, the bottom of the electric lifting rod is fixedly connected to the top surface of the base, and the top surface of the electric lifting rod is rotatably connected to the bottom surface of the support plate. Furthermore, the number of electric lifting rods is no less than four. In this embodiment, four electric lifting rods are provided, which are rotatably connected to the four corners of the bottom surface of the support plate, including: a first electric lifting rod, a second electric lifting rod, a third electric lifting rod, and a fourth electric lifting rod; the distance between the third and fourth electric lifting rods and the bending machine is less than the distance between the first and second electric lifting rods and the bending machine; wherein the rotatable connection adopts a hinge; in other embodiments, the number and installation position of the electric lifting rods can be set according to requirements. The clamping module includes: robotic arms; robotic arms are installed on both sides of the support plate; The control module includes: a controller and control switches; The control switches, electric lifting rod, and robotic arm are all electrically connected to the controller. The control switch is used to input the lifting signal of any electric lifting boom and the action signal of any robotic arm, and send them to the controller; Specifically, the control switches include: electric lifting pole switches and robotic arm switches; The electric lifting pole switch includes: an up switch, a down switch, an outer up switch, an outer down switch, an inner up switch, and an inner down switch; Robotic arm switches include: gripping switches, release switches, clockwise rotation switches, and counterclockwise rotation switches; The control switch can be operated by the worker and adjusted according to the specific processing process; however, in this embodiment, the control switch is set on the foot switch, and the electric lifting rod switch and the robotic arm switch are respectively set on both sides of the base, so that it is controlled by two workers respectively when the worker is processing. The controller is used to control the raising and lowering of the corresponding electric lifting rod based on the lifting signal; Used to control the corresponding robotic arm to perform actions based on motion signals; Specifically, by triggering the rise switch once, a rise signal is input to control the rise of all electric lifting masts; by triggering it again, a stop signal is input. The controller controls all electric lifting masts to rise according to the rise signal and controls them to stop rising according to the stop signal. By triggering the descent switch once, a descent signal is input to control the descent of all electric lifting masts. A stop signal is input upon triggering the switch again. The controller controls all electric lifting masts to descend based on the descent signal and stops descent based on the stop signal. By triggering the outer rise switch once, an outer rise signal is input to control the rise of the first and second electric lifting rods on the outside. When triggered again, a stop signal is input. The controller controls the first and second electric lifting rods on the outside to rise according to the outer rise signal, and controls the electric lifting rods to stop rising according to the stop signal. By triggering the outer lowering switch once, an outer lowering signal is input to control the lowering of the first and second electric lifting rods on the outside. Upon triggering again, a stop signal is input. The controller controls the first and second electric lifting rods on the outside to lower according to the outer lowering signal, and controls the electric lifting rods to stop lowering according to the stop signal. By triggering the inner lifting switch once, an inner lifting signal is input to control the third and fourth electric lifting rods to rise. Upon triggering again, a stop signal is input. The controller controls the third and fourth electric lifting rods to rise according to the inner lifting signal, and controls the electric lifting rods to stop rising according to the stop signal. By triggering the inner descent switch once, an inner descent signal is input to control the descent of the third and fourth electric lifting rods. Upon triggering again, a stop signal is input. The controller controls the descent of the third and fourth electric lifting rods based on the inner descent signal, and controls the electric lifting rods to stop descent based on the stop signal. In addition, there is a height difference constraint between the first and second electric lifting rods on the outside and the third and fourth electric lifting rods on the inside. That is, the height difference between the two cannot exceed the preset height difference. If it does, the lifting or lowering will stop. By triggering the clamping switch, a clamping signal is input to the robotic arm; based on the clamping signal, the controller generates robotic arm movement data using machine vision technology and end-effector positioning technology, controls the robotic arm to move to one side of the workpiece, and clamps the workpiece.

[0027] In other embodiments, the controller can also automatically control the lifting support module to lift and lower, and control the clamping module to clamp and rotate, according to the bending program currently being executed by the bending machine.

[0028] Example 2 This embodiment is basically the same as the above embodiment, except that it also includes a detection module; The detection module is electrically connected to the control module and is used to detect the distance information between the support plate and the workpiece, and send it to the control module. The control module is also used to control the lifting support module to lift and lower based on distance information; Specifically, the detection module includes: several grooves set on the top surface of the support plate; in this embodiment, the grooves are set at the midpoint of the line connecting the outer lifting support rods connected to the bottom of the support plate and the midpoint of the line connecting the inner lifting support rods, for a total of two grooves; A distance sensor is provided inside the groove, including: a first distance sensor and a second distance sensor; The distance sensor is electrically connected to the controller to detect the distance between the support plate and the workpiece, and generates distance information to send to the controller. The controller is used to adjust the height of the electric lifting rod on the outer or inner side of the distance sensor whose distance information does not conform to the preset distance range, so that the distance information conforms to the preset range. Specifically, the preset distance range is less than a first preset distance value and greater than a second preset distance value, where the second preset distance value is greater than the first preset distance value. Correspondingly, when there is no workpiece on the support plate, the distance value detected by the distance sensor will be large, while when a workpiece is placed, the distance value detected by the distance sensor will be small. Therefore, two preset distance values ​​are set to correspond to the cases where no workpiece is placed and the cases where a workpiece is placed. When the bending machine bends, the workpiece will bend and move, and the distance value will increase. When it exceeds the first preset distance value, the corresponding outer electric lifting rod or inner electric lifting rod is controlled to rise to control the distance value not to exceed the first preset distance value. If the distance information transmitted by the first distance sensor does not match the preset distance range, the outer electric lifting rod will be raised. If the distance information transmitted by the second distance sensor does not match the preset distance range, the inner electric lifting rod will be raised. If the distance information transmitted by the first distance sensor and the second distance sensor does not match the preset distance range, then all electric lifting masts will be controlled to rise.

[0029] In other embodiments, four grooves may be provided corresponding to the position of the lifting support rod connected to the bottom of the support plate; The groove is equipped with a distance sensor, including: a first distance sensor, a second distance sensor, a third distance sensor and a fourth distance sensor; The distance sensor is electrically connected to the controller to detect the distance between the support plate and the workpiece, and generates distance information to send to the controller. The controller is used to adjust the height of the electric lifting rod below the distance sensor when the distance information does not conform to the preset distance range, so that the distance information conforms to the preset range, thereby enabling more precise control.

[0030] Example 3 This embodiment is basically the same as the above embodiment, except that the control switch also includes a detection switch; A single trigger of the detection switch activates the distance sensor in the control module, and a subsequent trigger activates the distance sensor, deactivating it. The controller activates the distance sensor based on the activation signal and deactivates it based on the deactivation signal, thus controlling the opening and closing of the detection module for convenient operation in suitable processing environments. Other embodiments may include a conveyor belt on the side of the lifting support module for transporting workpieces to the support plate, further reducing worker workload.

[0031] Example 4 This embodiment is basically the same as the above embodiment, except that: the support plate is divided into an outer plate and an inner plate; the outer plate and the inner plate are connected by a telescopic rod; the first electric lifting rod and the second electric lifting rod are set on the bottom surface of the outer plate; the third electric lifting rod and the fourth electric lifting rod are set on the bottom surface of the inner plate; when the outer plate or the inner plate rises or falls individually, the telescopic rod stretches or contracts, so that there is a height difference constraint between the first electric lifting rod and the second electric lifting rod and the third electric lifting rod and the fourth electric lifting rod on the inner side. The preset height difference can be larger, better fit the workpiece, and support the workpiece.
