Description

Technical Field

[0001] The utility model belongs to the technical field of busbar processing, and particularly relates to a laser thickness detector for bending busbars. Background Art

[0002] A busbar refers to the copper or aluminum bar connecting the main switch in the electric cabinet and the switches in each branch circuit in the power supply system. The surface is insulated, and its main function is to be used as a conductor.

[0003] The processing technology of busbars mainly includes punching, riveting, and bending. Since the texture of busbars is relatively soft, unnecessary deformation is likely to occur after the bending process. Therefore, it is necessary to detect the thickness of the bent parts. However, the current detection methods are still relatively primitive. The thickness of the workpiece is mainly detected by manually holding a caliper. The labor intensity of workers is high, and there are many uncertain factors in manual detection, which are prone to errors. This detection method is not applicable to modern automatic production either. Content of the Utility Model

[0004] Purpose of the utility model: To overcome the above deficiencies, the purpose of the utility model is to provide a laser thickness detector for bending busbars. In the utility model, a transfer robot is used to place the bent busbar workpiece on the inspection table. After the photoelectric switch recognizes the workpiece, the inspection electric cylinder drives the slide plate to move along the linear guide rail, so that the busbar workpiece is located below the laser thickness sensor. The flattening cylinder in the flattening mechanism drives the flattening block to press on the workpiece, making the workpiece fit with the plane of the inspection table. Finally, the laser thickness sensor emits laser and measures the thickness of the workpiece. After the detection is completed, the flattening mechanism rises, and the inspection electric cylinder drives the slide plate to send out the workpiece, and then the transfer robot takes the workpiece offline; the utility model realizes the automatic detection of the busbar thickness, improves the production efficiency, reduces the labor intensity of workers, and meets the requirements of modern automatic production.

[0005] Technical solution: To achieve the above purpose, the utility model provides a laser thickness detector for bending busbars, which includes an inspection table, an inspection feeding component, an inspection component, and a frame. The inspection table is arranged on the frame, and the inspection feeding component and the inspection component are arranged on the inspection table; the inspection feeding component can send the bent busbar to the inspection component to measure its thickness.

[0006] Preferably, the inspection feeding component includes an inspection table, an inspection electric cylinder, a slide plate, and a linear guide rail. The linear guide rail and the inspection electric cylinder are arranged on the inspection table. The slide plate is connected to the linear guide rail through a slider. The inspection table is fixedly arranged on the slide plate, and the telescopic rod of the inspection electric cylinder is connected to the slide plate. A limit block is arranged on the inspection table. The inspection electric cylinder drives the slide plate to move back and forth on the linear guide rail, and the slide plate is limited by the limit block.

[0007] Specifically, the sample inspection table is stepped, and a groove that fits the shape of the bent workpiece is provided on the sample inspection table, and positioning protrusions are provided in the groove. The stepped sample inspection table can make the bent busbar workpiece fit better with it, and the busbar workpiece can just be inserted into the groove and positioned by the positioning protrusions.

[0008] Furthermore, the detection component includes a gantry, a flattening mechanism, a laser thickness sensor, and a translation mechanism. The gantry is erected on the detection table, the flattening mechanism and the laser thickness sensor are arranged on the gantry. The translation mechanism includes a lead screw, a nut sleeve, a motor, a travel switch, and a mounting plate. The mounting plate is arranged on the gantry. The lead screw is rotatably arranged on the mounting plate and connected to the motor. The nut sleeve is sleeved on the lead screw, and the laser thickness sensor is arranged on the nut sleeve. The motor drives the lead screw to rotate so that the nut sleeve linearly moves on the lead screw, and the nut sleeve drives the laser thickness sensor to move across the workpiece.

[0009] Guide rods are arranged on both sides of the lead screw, the nut sleeve passes through the guide rods, and the travel switch is slidably arranged on the side of the mounting plate. The travel switch limits the moving distance of the laser thickness sensor.

[0010] The flattening mechanism includes a flattening electric cylinder and a flattening block. The flattening electric cylinder is fixedly arranged on the gantry, and the flattening block is connected to the telescopic rod of the flattening electric cylinder.

[0011] The flattening block includes a flat pressing block and a leg pressing block. A notch is provided at one end of the flat pressing block, and the leg pressing blocks are arranged on both sides of the notch. The notch on the flat pressing block just corresponds to the detection part of the workpiece, and the laser can pass through the notch and shine on the workpiece. The flattening block is set in the form of a flat pressing block and a leg pressing block to fit the shape of the sample inspection table, and can flatten the workpiece on the sample inspection table to avoid affecting the detection result due to the workpiece warping.

[0012] Preferably, a detection bracket is arranged on the sliding plate. The detection bracket is located on the side of the sample inspection table, and a group of photoelectric switches are installed on the detection bracket. This group of photoelectric switches give signals after identifying that the busbar workpiece has reached the position on the sample inspection table, and then the detector starts to operate.

[0013] Furthermore, the detector further includes a protective cover, and a display screen is arranged on the protective cover.

[0014] Furthermore, a group of safety light curtains are also arranged at the end of the detection table. If a person or a machine is within the recognition range of the safety light curtain, the entire device will not start.

[0015] Even further, transfer robots are arranged on both sides of the detector, and vacuum suction cups are arranged at the ends of the transfer robots. The transfer robot on one side transfers the busbar workpiece on the bending station to the detector, and the transfer robot on the other side takes away the detected workpiece and sends it offline.

[0016] As can be seen from the above technical solution, the utility model has the following beneficial effects:

[0017] The purpose of the utility model is to provide a laser thickness detector for bending busbars. In the utility model, a transferred robot places the bent busbar workpiece on the inspection table. After the photoelectric switch recognizes the workpiece, the inspection electric cylinder drives the slide plate to move along the linear guide rail, so that the busbar workpiece is located below the laser thickness sensor. The flattening cylinder in the flattening mechanism drives the flattening block to press on the workpiece, so that the workpiece fits with the plane of the inspection table. Finally, the laser thickness sensor emits laser and measures the thickness of the workpiece. After the detection is completed, the flattening mechanism rises, the inspection electric cylinder drives the slide plate to send out the workpiece, and then the transferred robot takes the workpiece offline. The utility model realizes the automatic detection of the busbar thickness, improves the production efficiency, reduces the labor intensity of workers, and meets the requirements of modern automatic production.
