Description

Technical Field

[0001] The invention belongs to the technical field of watch case appearance inspection machines, and in particular relates to a double-sided watch case track-changing appearance inspection machine. Background Art

[0002] In the watch case manufacturing industry, appearance inspection is an indispensable part of ensuring product quality. Existing inspection methods usually rely on a long conveyor line, on which the watch case is transported to two different inspection positions, and the inspection is carried out on the corresponding sides of the two positions to cover the two corresponding sides of the watch case. Although this inspection method meets the needs of quality inspection to a certain extent, there are significant efficiency bottlenecks and flexibility limitations. Specifically, the long conveyor line not only takes up a lot of production space, but also increases the time cost of the watch case during the transportation process, thereby affecting the overall production efficiency. In addition, since the inspection needs to be carried out at two different positions, the configuration and maintenance costs of the equipment are also relatively high. More importantly, for watch cases of different shapes and sizes, the existing inspection methods are often difficult to adapt and lack sufficient flexibility.

[0048] Reference Figures 1 to 16 The working principle of the double-sided case track-changing appearance inspection machine of the present invention is as follows:

[0049] Place multiple trays with watch cases 9 on top of each other on the loading plate 82, and move the loading plate 82 downward to adjust its height;

[0050] The push cylinder 871 at the right end of the front fixed rail 14 pushes the multiple slide frames 46 on the side of the corresponding carrier 4 through the multiple push rods 872. The slide frames 46 slide in the sliding sockets and compress the push springs 491 until the limiting column 483 of one of the sliders 48 is located in the limiting groove 461 and presses against the side wall of the limiting groove 461, and the limiting column 483 of the other slider 48 climbs up the boss 462 along the inclined surface 463. At this time, the two sliders 48 slide synchronously in their respective slide grooves toward the center direction of the carrying plate 45, and the two springs 484 are compressed, and the carrier 4 is opened;

[0051] The multiple clamping cylinders 811 of the loading robot 81 clamp a row of watch cases 9 in the top tray on the loading plate 82 and place them on the opened carrier 4;

[0052] The push cylinder 871 in the front pulls the multiple push rods 872 to retract (external force is withdrawn), and the slide frame 46 is reset under the action of multiple push springs 491. One of the sliders 48 slides outward under the action of the corresponding spring 484, so that its limit column 483 withdraws from the limit slot 461; the other slider 48 slides outward under the action of the corresponding spring 484, so that its limit column 483 retreats from the boss 462 to its original position. At this time, the carrier is closed. Since the inner hole of the watch case 9 is slightly larger than the size of the limit platform 452, the watch case 9 will adjust its position under the push of the two sliders 48. The notches 482 of the two sliders 48 respectively press against the two adjacent inner walls of the watch case 9, and the other two adjacent inner walls of the watch case 9 press against the two adjacent outer walls of the limit platform 452 on the top of the carrier plate 45. The carrier 4 fixes the watch case 9 from the inside of the watch case 9, and the carrier 4 is closed.

[0053] The conveying motor 71 at the front controls the driving gear 711 at its output end to rotate, thereby driving the conveying belt 7 at the front to run through the belt transmission, and the conveying belt 7 at the front drives the multiple carriers 4 carrying products at the front side to move from right to left;

[0054] When the carrier 4 carrying multiple watch cases 9 moves to the right below the pressing plate 85, the pressing plate 85 descends (the pressing plate 85 can be driven to rise and fall by a lifting cylinder) to press the multiple watch cases 9 carried on the corresponding carrier 4, and the perforation CCD detection machine 86 detects the water guide holes on the front side of the watch case 9 to detect whether the water guide holes penetrate the front side wall of the watch case 9. After the detection is completed, the pressing plate 85 moves up and resets, and the carrier 4 further moves to the left;

[0055] When the carrier 4 to be inspected moves to the front CCD inspection machine 861, the front CCD inspection machine 861 inspects whether the direction of the water guide hole on the front side of the watch case 9 is processed incorrectly. After the inspection is completed, the carrier 4 moves further to the left;

[0056] When the carrier 4 that has been detected on the front side moves further to the upper bearing rail 2 of the left base 1, the lower bearing rail 3 on the right is empty (that is, there is no carrier 4 on the lower bearing rail 3 on the right), and the upper bearing rail 2 on the left base 1 drives the carrier 4 it carries to slide backward along the two upper slide rails 11, and the motor 6 on the left base 1 drives the first belt 61 on the left and the second belt 62 on the left to run synchronously, pulling the empty lower bearing rail 3 on the left to move horizontally, downwardly obliquely, horizontally, upwardly obliquely and horizontally in sequence, and then without changing the direction of the carrier 4 on the left upper bearing rail 2, the positions of the left lower bearing rail 3 and the left upper bearing rail 2 are exchanged, so that the upper bearing rail 2 on the left carrying the carrier 4 is docked with the fixed rail 14 at the rear, and the carrier 4 carried on the upper bearing rail 2 on the left is meshed with the conveyor belt 7 at the rear, and the empty lower bearing rail 3 on the left (that is, there is no carrier 4 on the lower bearing rail 3 on the left) is docked with the fixed rail 14 in front;

[0057] The rear conveying motor 71 controls the driving gear 711 at its output end to rotate, thereby driving the rear conveying belt 7 to run through the belt transmission, and the rear conveying belt 7 drives the multiple carriers 4 at the rear side to move from left to right;

[0058] When the case 9 whose front side has been inspected moves to the rear CCD inspection machine 862 along with the carrier 4, the rear CCD inspection machine 862 inspects whether the direction of the water guide hole on the rear side of the case 9 is processed incorrectly. At this time, the double-sided inspection of the case 9 is completed, and the carrier 4 moves further to the right.

[0059] When the watch case 9 after inspection is moved to the carrier opening and closing mechanism 87 at the rear along with the carrier 4, the rear push cylinder 871 pushes the plurality of push rods 872 to press the plurality of slide frames 46 corresponding to the carrier 4, and opens the carrier 4 after the appearance inspection of the watch case 9;

[0060] The unloading robot 842 grabs a row of the tested watch cases 9 through its clamping cylinder 811, and then puts the row of watch cases 9 into the defective product tray of the defective product unloading plate 841 and the good product tray of the good product unloading plate 84 according to the previous test results, leaving the carrier 4 empty;

[0061] The empty carrier 4 continues to move rightward until the empty carrier 4 at the rightmost end of the rear fixed rail 14 moves to the upper bearing rail 2 on the right, and the upper bearing rail 2 on the right base 1 drives the empty carrier 4 it carries to slide forward along the two upper slide rails 11, and the motor 6 on the right base 1 drives the first belt 61 on the right and the second belt 62 on the right to operate synchronously, pulling the empty lower bearing rail 3 on the right to move horizontally, move obliquely downward, move horizontally, move obliquely upward and move horizontally in sequence, and then without changing the direction of the empty carrier 4 on the upper bearing rail 2, the position of the lower bearing rail 3 and the upper bearing rail 2 are exchanged, so that the upper bearing rail 2 carrying the empty carrier 4 is docked with the fixed rail 14 in front, and the empty carrier 4 on the upper bearing rail 2 is meshed with the conveyor belt 7 in front, and the empty lower bearing rail 3 is docked with the fixed rail 14 at the rear;

[0062] The multiple carriers 4 on the front conveying path move from right to left along with the front conveyor belt 7. The empty carriers 4 on the upper bearing rail 2 on the right move to the front fixed rail 14 along with the front conveyor belt 7. The carrier opening and closing mechanism 87 in front opens the carrier 4. The loading robot 81 again absorbs a row of watch cases 9 from the top tray of the loading plate 82 and places the row of watch cases 9 on each empty carrier 4 carried by the front fixed rail 14.

[0063] After the carrier 4 carrying the product is inspected on the front conveying path, it moves to the base 1 on the left. Then, the two bearing rails on the left base 1 repeatedly exchange positions, and the carrier 4 carrying the product at the left end of the front conveying path is transferred to the left end of the rear conveying path. Then, the unloading is inspected, and then the two bearing rails on the right base 1 repeatedly exchange positions, and the empty carrier 4 carried at the right end of the rear conveying path is transferred to the right end of the front conveying path. This cycle is repeated, and the two conveying paths are connected into a circular one-way conveying line (see Figure 5 , Figure 5 The different states of all carriers 4 are superimposed together, that is, there are actually two empty positions without carriers 4 on the entire conveyor line);

[0064] When all the watch cases 9 in a single tray on the loading plate 82 are inspected, the multiple suction nozzles 812 of the loading robot 81 suck the empty trays on the loading plate 82 and place them on the empty tray placement plate 83, and stack the multiple empty trays;

[0065] When the empty pallets on the defective product unloading plate 841 and the good product unloading plate 84 are used up, the multiple suction nozzles 812 of the unloading robot 842 suck the empty pallets on the empty tray placement plate 83 and stack them on the defective product unloading plate 841 and the good product unloading plate 84.

[0066] The double-sided watch case changeable track appearance inspection machine of the present invention has two bases 1 connected by two fixed rails 14 arranged at intervals to form two conveying paths. A track change mechanism 42 is used to control the up and down movement of one bearing rail, and the longitudinal sliding of the other bearing rail is coordinated to swap the positions of the two bearing rails, so that the two conveying paths are connected into a ring-shaped one-way conveying line with a more compact structure. At the same time, a front CCD inspection machine 861 and a rear CCD inspection machine 862 are respectively provided on the sides of the two fixed rails 14 to comprehensively inspect the double-sided appearance of the watch case 9 product. The entire inspection machine adopts a more compact and efficient layout, which reduces the occupied production space, reduces maintenance costs, and improves production efficiency and the flexibility of appearance inspection.

[0067] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
