DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 The utility model provides a technical solution: a size detection device for a battery nickel sheet welding machine, comprising a base 1, four groups of longitudinal support rods 2 are evenly arranged on the upper end of the base 1, the upper end of the longitudinal support rods 2 is connected with a mounting seat 3, two groups of clamping tube blocks 4 are arranged on the longitudinal support rods 2, transverse support tubes 5 are inserted in the clamping tube blocks 4, and a light emitting plate 6 is installed on the upper side of the other end of the transverse support tube 5.

[0019] The light homogenizing plate 6 is fixed on the longitudinal support rod 2 through the tube clamping block 4 and screws, and the tube clamping block 4 is movably installed on the longitudinal support rod 2 in an upper and lower position.

[0020] Furthermore, when the height of the light-diffusing plate 6 needs to be adjusted, the screws can be loosened first, and then the positions of the two sets of tube clamping blocks 4 on the longitudinal support rod 2 can be adjusted synchronously. After the adjustment, the positions of the tube clamping blocks 4 can be fixed by tightening the screws to achieve the height adjustment of the light-diffusing plate 6.

[0021] A fixing seat 7 is mounted on the upper end surface of the mounting seat 3 by means of screws.

[0022] The fixing seat 7 is in a right triangle structure, and a plurality of screw holes are evenly arranged in the vertical direction of the fixing seat 7. The longitudinal section of the slide rail 9 is in an inwardly contracted trapezoidal structure.

[0023] Furthermore, the plurality of screw holes on the fixing seat 7 can be used to screw the slide rail guide plate 8 into corresponding holes as required to adjust the installation position of the slide rail guide plate 8 .

[0024] A slide rail guide plate 8 is fixed to one end face of the fixed seat 7 by screws, a slide rail 9 is arranged on the slide rail guide plate 8, and tooth grooves 14 are evenly arranged on the protruding end face of the slide rail 9. An upper slider 10 and a lower slider 11 are movably mounted on the slide rail 9. A first mounting plate 13 is fixed to the upper slider 10 by screws, a CCD visual camera 15 is mounted on the first mounting plate 13, and a second mounting plate 16 is fixed to the lower slider 11 by screws, and a camera light source 17 is mounted on the second mounting plate 16.

[0025] In one embodiment, when the product to be inspected is conveyed onto the light emitting plate 6, the CCD visual camera 15 and the camera light source 17 are started, and the camera light source 17 is used to illuminate the product to provide sufficient light source, and then the CCD visual camera 15 is used to photograph the product placed on the light emitting plate 16, thereby performing size detection on the product to be inspected.

[0026] A gear plate 20 is installed inside the upper slider 10 and the lower slider 11. A servo motor 25 is provided on one side of the gear plate 20 and installed on the inner wall of the slider. The output shaft of the servo motor 25 is connected to the rotating shaft 23 through a coupling, and the other end of the rotating shaft 23 is inserted into the gear plate 20. A plurality of groups of convex teeth 21 are evenly arranged on the outer wall of the gear plate 20, and the convex teeth 21 are correspondingly engaged in the tooth grooves 14. An electric cylinder 18 is provided on the other side of the tooth groove 14 facing the gear plate 20. A telescopic arm 19 is provided on the electric cylinder 18. When the equipment is not working, the electric cylinder 18 can be started to drive the telescopic arm 19 to insert into the gap of the convex teeth 21, thereby limiting the position of the gear plate 20 and thus limiting the height of the slider.

[0027] The upper slider 10 and the lower slider 11 are both spirally installed with adjusting nuts 12, and the adjusting nuts 12 are connected with a locking tongue 22 near the inner side of the slider. The outer wall of the gear plate 20 near the adjusting nut 12 is evenly provided with a ring-shaped locking groove 24 with a blind hole structure. The locking tongue 22 is correspondingly spiraled in the locking groove 24. The adjusting nut 12 can also be manually rotated to drive the locking tongue 22 to be inserted into the locking groove 24 opened on the gear plate 20, so as to lock the position of the gear plate 20 and limit the height of the slider.

[0028] The rotating shaft 23 is fixedly connected to the gear plate 20 by spiral locking via a threaded gland.

[0029] In one embodiment, when the products to be inspected are of different sizes, it is necessary to adjust the distance between the CCD vision camera 15, the camera light source 17 and the light-diffusing plate 6. The adjustment method of the light-diffusing plate 6 has been described above and will not be repeated here. When it is necessary to adjust the height of the camera light source 17 and the CCD vision camera 15, first release the limit of the gear plate 20, and then start the servo motor 25 inside the slider. The servo motor 25 drives the rotating shaft 23 through the coupling to drive the gear plate 20 to rotate. When the gear plate 20 rotates, the convex teeth 21 are engaged in the tooth groove 14, so that it can move up and down on the slide rail 9 along the tooth groove 14. Therefore, the servo motors 25 inside the two groups of sliders can respectively drive the upper slider 10 and the lower slider 11 to move up and down, thereby adjusting the distance between the camera light source 17 and the CCD vision camera 15, so as to more clearly photograph and detect the products to be inspected.
