The first embodiment.

The present embodiment provides a checking apparatus that combines the laser welding sensor 7 with the welding table 1.

After the product is processed, the motor 4 is started to drive the telescopic mechanism a5 to rotate, the connecting plate 6 and the laser ranging sensor 7 are rotated to face the outer side of the workbench 1 from the relative inner side of the bottom of the workbench 1, and attention needs to be paid to the rotation to prevent the laser ranging sensor 7 from colliding with the workbench 1;

2. starting the telescopic mechanism a5 to drive the connecting plate 6 to extend out, and stopping when the connecting plate 6 completely extends out from the lower part of the workbench 1;

3. the motor 4 is started again to drive the laser ranging sensor 7 to rotate and rise from the bottom of the workbench 1, meanwhile, the telescopic mechanism a5 contracts to drive the connecting plate 6 to move towards the direction of the workbench 1, the motor 4 stops when the laser ranging sensor 7 is higher than a top platform of the workbench 1, and the telescopic mechanism a5 stops contracting when the connecting plate 6 contacts the side wall of the workbench 1;

4. laser rangefinder sensor 7 starts, measures the distance between its and the product on the workstation 1, and electronic slide rail 3 starts simultaneously, drives laser sensor 7 and slides along the workstation 1 lateral wall, and laser rangefinder sensor 7 on workstation 1 both sides will detect product both sides distance data and show, can know after the calculation whether processing is qualified for the product.

As shown in fig. 1, in the present embodiment, two inspection units 2 are provided at the bottom of the table 1, and when not in use, the operation is reversed from the above step 4, and the laser range finder sensor 7 is accommodated in the bottom of the table 1, that is, in the state of the inspection unit 2 on the right side in fig. 1.

The principle of calculation and analysis described in this embodiment can be seen in fig. 9, the metal support 12 product can be laid on the table 1 at will, and the laser distance measuring sensor 7 is in the state of step 4. The moving paths of the laser ranging sensors 7 on the two sides are from A to C and from D to F, wherein points A, B and C are three ranging detection points of the laser ranging sensor 7 on the right side, and only a plurality of points on the two sides of the product need to be detected, and the required data can be obtained without completely detecting the side walls of the product.

Similarly, D to F are the left detection points, the two laser ranging sensors 7 must be on the same axis and need to be synchronized, and the corresponding points a and D, B and E, D and F should be on the same axis.

The specific detection logic is that, taking the detection point a and the detection point D as an example, the distance from the point a measured by the right-side laser ranging sensor 7 is L1, the distance from the point D measured by the left-side laser ranging sensor 7 is L2, and finally the transverse distance between the point a and the point D is obtained by subtracting the sum of L1 and L2 from L, and similarly, after the distance from the point B to the point E and the distance from the point C to the point F are obtained, the three distances are compared, if the difference is smaller, the product can be accepted as a qualified product, if the difference is larger, the unqualified product is directly judged, and the unqualified product is taken down from the workbench 1 to wait for subsequent processing. When the quantity of the qualified products and the quantity of the unqualified products are equal to the required total quantity, whether the unqualified products are worth processing again is inspected, if the unqualified products can be processed, the unqualified products are immediately processed, and if the unqualified products cannot be processed, the unqualified products are directly scrapped and are reprocessed, so that the low efficiency of processing and detection can be avoided, and the problem of overlarge workload when all the products are uniformly detected can be avoided.

The laser distance measuring sensor 7 is generally connected with a computer, data is displayed on the computer through automatic software attached by a manufacturer, meanwhile, a calculation program can be preset, for example, when the L1 and L2 data are obtained, the sum of the two data is automatically subtracted by L to obtain the distance, meanwhile, the tolerance between the distances is preset, and when the error of the three-group distance or the array distance is larger than the preset tolerance, an alarm prompt can be given. The embodiment can be used as a basic scheme, has a plurality of improvement potentials, and can be used for carrying out more automatic improvement.

In the present embodiment, the parallel arrangement is based on the track direction of the electric slide rail 3, and since the slide rails of the two inspection units 2 are in the parallel state, the two units should be judged to be in the parallel state as a whole. Three actions are taken for driving the laser ranging sensor 7, one is that the motor 4 drives the telescopic mechanism to rotate, so that the laser ranging sensor 7 swings by taking the motor 4 as a center; secondly, the telescopic mechanism a5 moves telescopically to drive the laser ranging sensor 7 to move close to or away from the workbench 1; and thirdly, the electric slide rail 3 drives the laser ranging sensor 7 to slide in the horizontal direction. To reduce the design difficulty, it is default that when the retractable mechanism a5 is in the horizontal state, the laser beam detected by the laser range finder sensor 7 is parallel to the top surface of the table 1, and the detection distance is the shortest distance.

This embodiment can provide the preferred example, and because of the needs of laser rangefinder sensor 7 steady operation, connecting plate 6 need contact with workstation 1 under motor 4 drives, can set up reduction gears in theory and avoid both clashes, but for saving cost preferred adoption can cushion 14 of buffering the impact force, cushion 14 sets up at workstation 1 lateral wall, is rectangular form. Meanwhile, the connecting plate 6 slides along the workbench 1 under the driving of the electric sliding rail 3 due to the distance measurement requirement of the sensor 7, so that friction is generated between the connecting plate and the workbench, and the cushion pad 14 can be made of a low-friction material to reduce friction. The cushion pad 14 is not limited in material, and may be made of any feasible solution, such as dacron fabric, and is adhered to the workbench 1.

Example two.

In this embodiment, the laser distance measuring sensor 7 is detached from the connecting plate 6 and fixed to the retractable mechanism b8, so that the laser distance measuring sensor 7 is driven to move up and down along the connecting plate 6. Under the condition of not shortening the size of the connecting plate 6, the height of the laser ranging sensor 7 can be reduced, so that the height of the laser ranging sensor is lower than that of the connecting plate 6, and the sensor 7 can be in a safe state when the connecting plate 6 swings, and the phenomenon that the connecting plate collides with the workbench 1 or the ground is avoided. The present embodiment may allow for better protection of the laser range sensor 7 due to its higher value. And meanwhile, the device can also be suitable for products with different height sizes, and if the side wall of the product to be detected is higher, the sensor 7 can be lifted.

In the present embodiment, a preferable example is provided, and a preferable lifting manner for making the laser distance measuring sensor 7 more stable is adopted, that is, a slidable sliding plate 9 is provided on the connecting plate 6, the sliding plate 9 is tightly attached to the connecting plate 6, and slides along the connecting plate 6 under the driving of the telescopic mechanism b8, so as to push the sensor 7 to lift. Furthermore, sliding block tracks can be arranged on the sliding block 9 and the connecting plate 6, for example, the sliding block is arranged on the sliding block 9, and the connecting plate 6 is provided with tracks for the sliding block to slide, so that the sliding stability of the sliding block 9 is further improved.
