Abstract
Description
Technical Field
[0001] The utility model relates to the field of printer consumables, in particular to a positioning device. Background Art
[0002] Printers are an indispensable office equipment for production and life. Consumables boxes are consumable parts of printers. When a consumable box is used up, it is necessary to replace it with a new one. Consumables boxes on the market are all packaged with outer packaging, and are sold in the form of packages after packaging. In order to record the use of printing consumables installed in the printing device and to identify and authenticate the printing consumables, a detachable consumable chip is installed on the printing consumables, such as a toner chip on a toner cartridge. The toner chip is used to store relevant data of the toner cartridge, such as toner color, authentication code, serial number, remaining toner, page yield (maximum number of printable pages), number of printed pages, manufacturer, production date and other data.
[0003] When the consumable box is recycled after use and the consumable box is reworked, the above data will be rewritten, rewritten, reset and other read and write operations. It is necessary to use relevant read and write equipment to electrically connect with the consumable chip on the consumable box. When the consumable box is in a complete package, it is necessary to open the package to perform read and write operations on the consumable chip. In the prior art, a positioning piece is detachably installed on the consumable box, and the consumable box and the special positioning piece installed on the consumable box are packaged together in the consumable packaging box. When the read and write equipment performs read and write operations on the consumable chip on the consumable box, there is no need to manually position and align the contacts. Only a universal read and write device matching the positioning piece is needed to complete the read and write operations. However, when using the consumable box, the user needs to remove the positioning piece first, which is inconvenient to use, and each consumable box needs to be installed with a positioning piece, which increases the production cost.

The storage unit 21 is constructed to store information related to the processing box 100, such as toner color, authentication code, serial number, remaining toner amount, page yield (maximum number of printable pages), number of printed pages, manufacturer, production date and other data. The electrical contact portion 22 is arranged on one surface of the circuit board and exposed on the surface of the housing 1. When the processing box 100 is installed in the printing device, the electrical contact portion 22 is electrically connected to the printing device, thereby establishing communication between the chip 2 and the imaging device, so that the printing device can read the information in the storage unit. The number of the electrical contact portions 22 may be multiple. In this embodiment, the number of the electrical contact portions 22 is two.
[0027] The chip 2 also includes a detection contact 23, which is arranged on a surface of the circuit board. In this embodiment, the detection contact 23 and the storage unit 21 are arranged on the same circuit board and exposed on the surface of the housing 1.

[0028] like Figure 5 and 6 As shown, the positioning device 200 is connected between the upgrading device and the detection contact 23 of the chip 2, and is used for connecting and positioning the connection probe 220 in the positioning device 200. Specifically, the positioning device 200 includes a main body 210, a connection probe 220 and a fixing part 230. The connection probe 220 is fixed on the main body 210, and is used to burn or detect the program of the chip 2 to be operated. The fixing part 230 is formed by extending from the main body 210, and is used to fix the positioning device 200 on the processing box 100, so that the connection probe 220 can stably contact the detection contact 23 of the chip 2. The number of the connection probe 220 is one or more, which is determined according to the number of the detection contacts 23. The connection probe 220 is set as a retractable structure, so that the connection probe 220 can adapt to various chip structures, ensuring the stable contact between the connection probe 220 and the detection contact 23.
[0029] The positioning device 200 can be detachably mounted on the processing box 100 along the mounting direction, and the fixing portion 230 is arranged at the downstream end of the main body 210 in the mounting direction. The positioning device 200 is first positioned with the processing box 100 by the fixing portion 230, and the positioning device 200 is stably mounted on the processing box 100 to ensure the stable contact between the connection probe 220 and the detection contact 23 of the chip 2. The fixing portion 230 includes a first protrusion 230a, a second protrusion 230b and a third protrusion 230c, and the first protrusion 230a, the second protrusion 230b and the third protrusion 230c are all different in shape and size, and are asymmetrically arranged to form a foolproof structure to prevent the positioning device 200 from being inserted in the wrong direction or position. The shell 1 of the processing box 100 is provided with a first groove 1a corresponding to the shape and position of the first protrusion 230a, a second groove 1b corresponding to the shape and position of the second protrusion 230b, and a third groove 1c corresponding to the shape and position of the third protrusion 230c. When it is necessary to operate the chip 2, it is only necessary to install the positioning device 200 on the processing box 100 along the installation direction according to a predetermined posture, so that the first protrusion 230a is inserted into the first groove 1a for positioning, the second protrusion 230b is inserted into the second groove 1b for positioning, and the third protrusion 230c is inserted into the third groove 1c for positioning. At this time, the positioning device is restricted to the predetermined position, and the connection probe 220 fixed on the positioning device 200 can contact the detection contact 23 of the chip 2 and maintain a good contact state. Further, the first protrusion 230a, the second protrusion 230b and the third protrusion 230c are formed to extend substantially along the installation direction, and the outer peripheries of the first protrusion 230a, the second protrusion 230b and the third protrusion 230c are all provided with positioning ribs 240, and the outer peripheries of the positioning ribs 240 are formed to be slightly larger than the corresponding grooves, so that the protrusions of the positioning device 200 and the corresponding grooves on the processing box 100 form an interference fit, so that the fixing portion 230 of the positioning device 200 can better adapt to the corresponding structures of different processing boxes 100, reducing the design difficulty of the positioning device 200.

When it is necessary to process the chip of different processing boxes 100, different positioning devices 200 can be directly replaced to achieve upgrade processing of different chips, and the operation is simple and convenient.
[0030] like Figure 7 and 8 As shown, in the actual production and sales process, the consumable box needs to be placed in the outer package 300 for transportation and sales. The outer package 300 is roughly in the shape of a rectangular parallelepiped, and a square accommodating portion is formed therein. The accommodating portion is used to accommodate one or more consumable boxes. As shown in the figure, this embodiment is described by taking the outer package 300 accommodating a consumable box as an example. An opening 301 is provided on one side of the outer package 300. The chip 2 of the consumable box is arranged corresponding to the opening 301, so that the detection contact 23 of the chip 2 is exposed outside the outer package 300 through the opening 301. The positioning device 200 can be inserted into the outer package 300 through the opening 301 and connected with the detection contact 23 of the chip 2. In this way, the chip upgrade, reset and other operations can be completed without removing the outer package 300, reducing the scrapping of packaging materials. When it is necessary to process the chip of different processing boxes 100, different positioning devices 200 can be directly replaced to achieve upgrade processing of different chips. There is no need to install special positioning parts in the outer packaging. Users do not need to remove the positioning parts when using the consumable box and can use it directly, which facilitates the installation and use of the processing box 100 and reduces packaging costs and production costs.
[0031] In actual applications, in order to protect the chip from being damaged during transportation, a cover is provided at the corresponding position of the opening, the cover covers and seals the opening, and the cover includes a covering portion and an operating portion, the covering portion covers the corresponding opening, and the operating portion extends from the covering portion to the outside of the surface of the outer package, and when the chip needs to be operated, the user can operate the operating portion to remove the cover. The cover is a tearable film, specifically a transparent film, and after the chip is operated, the cover can be re-attached to proceed to the next step.
