[0052] During use, the two-dimensional force detection mechanism provided in this application document can simultaneously detect the rotating part, push-pull part and gap of the same product, or it can only detect one or several structures of the same product. The specific details are determined based on actual conditions and will not be elaborated here.
[0053] This specific embodiment discloses a two-dimensional force detection mechanism, including:
[0054] A clamping jaw assembly that can be opened or clamped to loosen or clamp the rotating part of the product;
[0055] A rotating assembly, wherein the clamping jaw assembly is connected to an output end of the rotating assembly;
[0056] A suction component, used to suck the push-pull part of the product;
[0057] A push-pull component, wherein the suction component is connected to the output end of the push-pull component;
[0058] A two-dimensional force detection component, the rotating component and the push-pull component are both connected to the two-dimensional force detection component, and are used to detect the torque at the output end of the rotating component and the push-pull force at the output end of the push-pull component in real time;
[0059] A control device, used for receiving the torque and push-pull force detected by the two-dimensional force detection component, and comparing the received torque with the preset torque, and comparing the received push-pull force with the preset push-pull force; when the received torque is within the preset torque range, it is judged that the rotating part of the product is qualified, and when the received torque is outside the preset torque range, it is judged that the rotating part of the product is unqualified; when the received push-pull force is within the preset push-pull force range, it is judged that the push-pull part of the product is qualified, and when the received push-pull force is outside the preset push-pull force range, it is judged that the push-pull part of the product is unqualified;
[0060] The clamping jaw assembly, rotating assembly, suction assembly, push-pull assembly and two-dimensional force detection assembly are all connected to a control device, which can control the actions of the clamping jaw assembly, rotating assembly, suction assembly, push-pull assembly and two-dimensional force detection assembly.
[0061] In order to enable the clamping jaw assembly to smoothly clamp the rotating part of the product, the clamping jaw assembly may include a clamping jaw power member and at least two clamping blocks 1 that can be relatively opened or clamped, the clamping blocks 1 being connected to the output end of the clamping jaw power member; the clamping jaw power member is connected to the output end of the rotating assembly. The clamping block 1 may be set to a structure that matches the shape of the rotating part to be clamped, so as to clamp the rotating part of the product.
[0062] Preferably, the hardness of the clamping block 1 is smaller than the hardness of the rotating part of the product to prevent the clamping block 1 from damaging the product during the clamping process.
[0063] The clamping jaw power member may be a clamping jaw cylinder 2 or a structure such as a motor 3 that can provide power, which is determined according to actual conditions.
[0064] In the process of using the two-dimensional force detection mechanism provided in this specific embodiment, a rotating part and a push-pull part are provided in the product to be detected. During detection, the torque of the rotating part of the product can be detected first, or the push-pull force of the push-pull part of the product can be detected first, or the rotating part and the push-pull part can be detected at the same time, depending on the actual situation.
[0065] During inspection, the control device controls the clamping jaw assembly to clamp the rotating part of the product, and then controls the rotating assembly to drive the clamping jaw assembly to rotate. The two-dimensional force detection assembly detects the torque at the output end of the rotating assembly in real time, and transmits the torque to the control device in real time. The control device compares the received torque with the preset torque. When the received torque is within the preset torque range, the rotating part of the product is judged to be qualified. When the received torque is outside the preset torque range, it may be greater than the maximum value of the preset torque, or less than the minimum value of the preset torque, then the rotating part of the product is judged to be unqualified.
[0066] The control device controls the suction component to suck the push-pull part of the product, and then controls the movement of the push-pull component to push the push-pull part to another position, or pulls the push-pull part to another position. The two-dimensional force detection component detects the push-pull force of the output end of the push-pull component in real time, and transmits the push-pull force to the control device. The control device compares the received push-pull force with the preset push-pull force. When the received push-pull force is within the preset push-pull force range, the push-pull part of the product is judged to be qualified. When the received push-pull force is outside the preset push-pull force range, it may be greater than the maximum value of the preset push-pull force, or less than the minimum value of the preset push-pull force, the push-pull part of the product is judged to be unqualified.
[0067] A corresponding display screen can be set on the control device to display the detected torque and push-pull force in real time in the form of curves or other charts on the display screen, so that users can observe the torque information conveniently. When the torque is detected to be greater than the maximum value of the preset torque range, a safe torque value can be set to avoid damage to the rotating component caused by excessive torque. When the torque is detected to be greater than or equal to the safe torque value, the control device controls the rotating component to stop rotating; the safe torque value must be greater than or equal to the maximum value of the preset torque.
[0068] Compared with the prior art, the two-dimensional force detection mechanism provided in this specific embodiment can detect both the torque of the rotating part of the product and the push-pull force of the push-pull part of the product. The same two-dimensional force detection mechanism can be used to complete the detection of torque and push-pull force, avoiding the tedious operation of replacing the detection equipment in the middle, and simplifying the process of two-dimensional force detection of the product; in addition, the control device of the two-dimensional force detection mechanism provided by the present invention can compare the detected torque with the preset torque, and compare the detected push-pull force with the preset push-pull force, so that the judgment process is quick and convenient.
[0069] In order to avoid affecting the connection of the electrical circuit during the rotation of the jaw assembly driven by the rotating assembly, an electrical slip ring 4 can be set between the jaw power component and the rotating assembly so that the circuit and air circuit of the two-dimensional force detection mechanism can rotate freely in the rotating position without entanglement with the pipeline.
[0070] It should be noted that the two-dimensional force detection component can be a combination of two detection mechanisms, including a torque detection mechanism connected to the rotating component and a push-pull force detection mechanism connected to the push-pull component; both the torque detection mechanism and the push-pull force detection mechanism are connected to the control device.
[0071] Of course, the two-dimensional force detection component can also be a separately set two-dimensional force detection sensor 11 that can detect torque and push-pull force at the same time. The rotating component and the push-pull component are both connected to the two-dimensional force detection sensor 11, and the two-dimensional force detection sensor 11 is connected to the control device.

[0076] During use, the combination of the line scan camera 7 and the laser transmitter 8 can be used to photograph the inside of the gap to determine the width of the gap and the uniformity of its width.
[0077] Of course, the line scan camera 7 can also be replaced by other shooting devices that meet the requirements, which will not be elaborated here.
[0078] In addition to the above-mentioned two-dimensional force detection mechanism, the present invention also provides a robot including a manipulator and the two-dimensional force detection mechanism disclosed in the above-mentioned embodiment.
