The invention relates to the technical field of feeding equipment of component inserters, in particular to a chain clamp component correction mechanism for straightening electronic components. The chain clamp component correction mechanism comprises a correction main body and a left horizontal correction sheet and a right horizontal correction sheet which are arranged on the correction main body, the correction main body is provided with a horizontal driving device which drives the left horizontal correction sheet and the right horizontal correction sheet to be close to or far from each other, a component passing channel is opened on the correction main body, correction notches expanding inside and contracting outside are opened on the right end portion of the left horizontal correction sheet and the right horizontal correction sheet. When the left horizontal correction sheet and the right horizontal correction sheet are close to each other, the correction notch of the left horizontal correction sheet is jointed to the correction notch of the right horizontal correction sheet, and the component passing channel is place below the jointing position of the two correction notches. The chain clamp component correction mechanism has the advantages that the structure is simple, the maintenance and the overhaul are convenient, accuracy rate of clamping and inserting of other components of the inserters are improved after electronic components on the feeding chain clamp are straightened.

The invention discloses a method for calibrating the odometer of a differential mobile robot. The method includes: step 1: the robot walks in a preset area, and uses a motion capture system to position the vehicle; step 2: transmits the walking displacement of the robot to The processor reads the walking displacement calculated by the robot odometer at the same time; step 3: calculates the compensation parameters based on the walking displacement of the robot obtained by the motion capture system and the walking displacement calculated by the odometer, and compensates the motion capture system; step 4 : Repeat step 1-step 3, and iteratively correct the compensation parameters until the robot's walking route is consistent with the setting, realizing the technical effect of high calibration efficiency and precision of the differential mobile robot.

A projector lens assembly and a projector, the projector lens assembly includes a reflector, a mounting assembly, a drive structure, a first drive assembly, a first bracket and a first lens group, the reflector is arranged on the mount assembly, and the reflector is used for The projected picture is projected to the target position, the driving structure is used to drive the mounting assembly to drive the reflector to rotate, so as to correct the projected picture at the target position, the first lens group is arranged on the first bracket, and the first driving component is used to drive the first bracket Drive the first lens group to move close to or away from the reflector to make the focus clear. The driving structure drives the mounting assembly to drive the reflector to rotate, and adjusts the reflection direction of the reflector to eliminate the distortion of the projection screen. The first drive assembly drives the first bracket to drive the first lens group with focusing function to move closer to or away from the reflector. , to complete the focusing, so as to realize the focusing function and the correction function of the projected picture at the same time.

The invention provides a precision concentricity correcting tool. The tool achieves the function of correcting the concentricity between an oil bearing and a motor end cover through a correcting mandrel, achieves the positioning function by matching of an end cover base, a bearing block and a support rod, achieves the limit function by matching of a movable upper plate, a limit block and a fixed base plate, achieves the guiding function by matching of a linear guide bearing, a guide post and a limit stop, and achieves the tool resetting function by matching of a spring and a butterfly gasket.The tool can eliminate the gap between the oil bearing and the motor end cover, so that the oil bearing can be assembled into the motor end cover. The tool can further control the concentricity deviation between the oil bearing and the motor end cover to be small to ensure the assembly precision, and further ensure the normal operation of the motor and greatly prolong the service life of the motor.

An asynchronous pixel array with an arbitration time error correction function comprises a pixel array, a row arbitration selector connected with the pixel array, a row address coder connected with the row arbitration selector, a column arbitration selector connected with the pixel array, a column address coder connected with the column arbitration selector and an external communication preparation module which is respectively connected with the pixel array, the row address coder, the column address coder and an external processing module. The asynchronous pixel array with the arbitration time error correction function is further provided with a time error correction processing module which is respectively connected with the pixel array, the row address coder, the column arbitration selector, the column address coder and the external communication preparation module. The measurement of the time from request sending of a pixel to being selected by the arbitration selectors is achieved, and therefore the function of correcting time error caused by arbitration awaiting. Under the condition that light intensity is relatively large and an event occurrence rate is relatively high, the effect of improving accuracy is relatively remarkable.
