Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of information input equipment, more particularly to a bar code dust removal device and method. BACKGROUND

[0002] Because bar codes can clearly and explicitly mark many information of articles, they have been widely used in the fields of commodity circulation, book management, postal management, etc. When bar code information is input, the bar code may be dirty and cannot be input. In order to solve this problem, the bar code is usually cleaned by a bar code dust removal device before formal information input.

[0003] The document with the prior art publication number CN213079225U provides a bar code dust removal device for Internet of Things. The device is convenient for cleaning bar codes on different height articles through the extension of the hydraulic telescopic shaft. At the same time, the cleaner is atomized and sprayed onto the bar code through the atomizing nozzle, which is convenient for removing the dust on the bar code and ensuring the cleaning effect.

[0004] Among many bar codes, there are bound to be some bar codes with difficult-to-clean dirt or damaged bar codes. These bar codes cannot be input after cleaning. When using the dust removal device of the above technical solution, these bar codes that cannot be input will be mixed with the bar codes that can be input. When scanning and inputting, the bar codes that cannot be input can only be picked out manually, which not only brings much inconvenience to the workers, but also seriously affects the efficiency of information input.

[0005] In view of this, we propose a bar code dust removal device and method. SUMMARY

[0069] The driving mechanism includes a second motor 611 fixedly mounted on the mounting frame 601 and a driving rack 609 fixedly mounted on the mobile frame 602. The output end of the second motor 611 is fixedly connected to a driving gear 608. The two driving racks 609 are arranged in a centrally symmetrical structure and mesh with each other.

[0072] The linear drive includes a rotating frame 614 fixedly mounted on the mounting frame 601 and a rotating mechanism.

The rotating frame 614 is fixed with a limit plate that slides with one side of the driving block 617. The driving block 617 is limited by the limit plate and slidably connected to it. The purpose of this arrangement is to allow the driving block 617 to move smoothly in a straight line when the reciprocating screw rod 616 rotates.

[0075] The movable plate 620 is provided with a plurality of groups of driving racks 621 arranged in a linear equidistant structure, each group of driving racks 621 comprises a plurality of uniformly distributed teeth, and since the driving racks 621 are arranged in a linear equidistant structure, the driving gear 619 will intermittently rotate, and the driving block 617 will also intermittently drive the code scanner 618 to move linearly, which enables the code scanner 618 to have sufficient time to scan each position on the object, further improving the accuracy of detection, and the driving rack 621 is in meshing cooperation with the driving gear 619.

[0076] The implementation principle of the preferred embodiment is that when the relevant staff needs to use the device to clean the bar code on the object, the staff first places the object on the conveyor belt 1 in sequence, under the action of the external control mechanism, the conveyor belt 1 intermittently runs, and when the object moves to the cleaning brush 7, the cleaning brush 7 rotates to clean the bar code on the object under the action of the first motor 5.

[0077] After cleaning, the conveyor belt 1 continues to run, and the object is immediately moved between the two moving frames 602. Under the action of the second motor 611, the driving gear 608 rotates, and since the driving gear 608 is in meshing connection with the driving rack 609, the driving rack 609 will drive the corresponding moving frame 602 to move inward, and the centering rod 606 follows the movement. When the roller 607 contacts the object, since the centering rod 606 is in rotational connection with the connecting plate 610, even if the object is in an inclined state, when the centering rod 606 contacts the object, the object will gradually be straightened.

[0078] With the continuous movement of the moving frame 602, the movable plate 620 follows the movement, and since the driving rack 621 is in meshing cooperation with the driving gear 619, the driving gear 619 will drive the reciprocating lead screw 616 to intermittently rotate, and the driving block 617 will also drive the code scanner 618 to intermittently move linearly, gradually scanning each position of the object.

[0079] If the identification is successful, the object continues to be transported by the conveying belt 1 to the appropriate position, and if the identification fails, when the object moves to the pushing plate 802, the electric push rod 801 operates under the control of the external control mechanism, and the pushing plate 802 then pushes the object away from the conveying belt 1. The object pushed away falls to the guide plate 3 and then slides along the guide plate 3 to the collection box 2 for collection. Such a reciprocating operation can complete the cleaning operation on the bar code on the object.

[0080] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit it. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solutions of the embodiments of the present application.

2. The barcode dust removal device according to claim 1, characterized in that: The driving mechanism comprises a second motor (611) fixedly mounted on the mounting frame (601) and a driving rack (609) fixedly mounted on the moving frame (602); the output end of the second motor (611) is fixedly connected to a driving gear (608); the two driving racks (609) are arranged in a centrally symmetrical structure; the driving gear (608) is meshedly connected to the driving rack (609).

3. The barcode dust removal device according to claim 2, characterized in that: The cleaning assembly comprises a support frame (4), a first motor (5) is fixedly mounted on the support frame (4), and a cleaning brush (7) is fixedly connected to the output end of the first motor (5).

4. The barcode dust removal device according to claim 3, characterized in that: A collecting box (2) is also fixedly provided on one side of the conveyor belt (1), and a guide plate (3) arranged in an inclined structure is fixedly installed on the collecting box (2). After the pushed objects fall onto the guide plate (3), they will slide along the guide plate (3) into the collecting box (2) for collection.

5. A barcode dust removal method, implemented based on the barcode dust removal device according to claim 4, characterized in that: The following steps are involved: The objects are sequentially placed on the conveyor belt (1). Under the action of an external control mechanism, the conveyor belt (1) intermittently drives the objects to move backward. When the objects move to the cleaning brush (7), the first motor (5) drives the cleaning brush (7) to rotate to clean the barcode on the objects. When the conveyor belt (1) drives the object to move between the two moving racks (602), the second motor (611) drives the driving gear (608) to rotate, driving the rack (609) to drive the corresponding moving rack (602) to move inward, the centering rod (606) moves accordingly, and the roller (607) contacts the object and causes the object to be gradually straightened; At the same time, the movable plate (620) moves accordingly, driving the gear (619) to drive the reciprocating screw (616) to rotate intermittently. At this time, the driving block (617) drives the barcode scanner (618) to move intermittently in a straight line, gradually scanning each position of the object; The object that has been successfully identified continues to be transported to an appropriate position by the conveyor belt (1), while when the object that has failed to be identified moves to the push plate (802), the electric push rod (801) operates under the control of the external control mechanism, and the push plate (802) then pushes the object away from the conveyor belt (1). After the object is pushed away and falls onto the guide plate (3), it will slide along the guide plate (3) into the collection box (2) for collection.
