Description

Technical Field

[0001] This utility model relates to the field of thermal printing technology, and in particular to an embedded thermal printer that can be quickly assembled and disassembled. Background Technology

[0002] With the widespread application of thermal printing technology, it has been widely used in the warehousing and logistics industry as well as in the printing of receipts and in other fields. Thermal printers include thermal transfer printers that use the principle of thermal transfer with carbon ribbon, and thermal printers that use thermal paper for thermal imaging. After thermal printing, the printed paper is output for users to use.

[0003] Embedded thermal printers are used to print labels, receipts, or payment slips within smart terminals or self-service terminals. Currently, a common problem with these embedded thermal printers is that their product models, assembly methods, and paper loading methods vary depending on the smart terminal or self-service terminal used. Therefore, the assembly and installation methods for different embedded thermal printers differ significantly. Thus, a relatively universal installation structure needs to be designed to facilitate standardized embedded assembly, and the connection structure should be optimized for easier signal connection. Utility Model Content

[0004] The purpose of this invention is to provide an embedded thermal printer that can be quickly assembled and disassembled.

[0005] To achieve the purpose of this utility model, this utility model provides a quick-assembly and disassembly embedded thermal printer, including a housing, a rubber roller, and a thermal sheet; the housing includes a base, a front cover, and a side cover, the thermal sheet is disposed inside the base, a paper tray is disposed inside the base, the rubber roller is rotatably disposed on the front cover, the front cover is connected to the front end of the base, and a paper outlet is formed between the front cover and the base, the side cover is connected to the first side end of the base and covers the outside of the paper tray, the thermal sheet and the rubber roller are opposite each other and form a paper feeding channel, the paper feeding channel connects the paper tray and the paper outlet; the housing is provided with assembly grooves on opposite sides in the horizontal left-right direction, the assembly grooves extend in the horizontal front-back direction, the assembly grooves are provided with an insertion opening at the rear end, and the assembly grooves are provided with a stop end face at the front end; one assembly groove is disposed on the outer surface of the side cover, and the insertion opening of the assembly groove on the side cover is disposed at the rear end edge of the side cover; the base is provided with a horizontal sidewall on the second side opposite to the side cover, and another assembly groove is disposed on the outer surface of the horizontal sidewall, and the insertion opening of the assembly groove on the base is disposed at the rear end edge of the horizontal sidewall.

[0006] A further improvement is to have a fixing connection hole through the upper part of the base.

[0007] A further proposed solution is to have both assembly slides located below the fixed connection holes.

[0008] A further proposed solution is to position the two assembly slides at the same horizontal level.

[0009] A further approach is to make the width of the insertion opening greater than the width of the stop face.

[0010] A further improvement is to make the width of the assembly slide gradually decrease from the rear end to the front end.

[0011] A further improvement is to have observation windows on the side cover along the horizontal front-to-back direction.

[0012] A further solution is that the embedded thermal printer includes a main control circuit board, which is set inside the base. The main control circuit board is equipped with connecting gold fingers that extend in a horizontal front-back direction and protrude from the rear end wall of the base.

[0013] A further proposed solution is to have both the main control circuit board and the connecting gold fingers located above the paper tray.

[0014] The beneficial effects of this utility model are that, through the horizontally arranged assembly slides on both sides of the housing and the insertion opening designed at its rear end, the embedded thermal printer can be directly pushed into the mounting position of the external device in the horizontal direction to achieve precise alignment and initial fixation. In addition, the stop end face at the front end of the slide can effectively limit the insertion depth of the printer to ensure proper installation. When maintenance or replacement is required, it can be pulled out in the reverse direction. The whole process does not require the use of cumbersome tools, which greatly simplifies the operation process and improves the efficiency of assembly and maintenance.

[0015] The printer can be finally secured to external devices using screws or other screws via the fixing connection holes on the base. Combined with the guiding and limiting functions of the assembly slides, this forms a dual fixing mechanism, ensuring the printer's structural stability and vibration resistance during operation. The two assembly slides are located at the same horizontal level and are preferably positioned below the fixing connection holes. This layout results in more rational force distribution and a more stable installation.

[0016] The design of the insertion opening being wider than the stop end face, and the assembly groove width gradually decreasing from front to back, provides good guidance, facilitating initial insertion and gradually tightening during the advancement process, thus improving the smoothness of installation and the tightness of the final fit.

[0017] The gold fingers of the main control circuit board are located at the rear of the base and extend horizontally. When the printer is installed into the self-service terminal or other equipment through the slide, the gold fingers can be inserted into the corresponding interface of the device's female connector. This design allows the electrical and data communication connections to be automatically established at the same time as the mechanical installation is completed, completely eliminating the cumbersome steps of connecting and fixing data cables in the traditional method. This not only simplifies the installation process but also reduces failures caused by unreliable cable connections, thus improving the overall reliability of the system.

[0018] Furthermore, the observation window on the side cover allows users or maintenance personnel to visually check the remaining paper level or operating status without disassembling the machine, facilitating timely replenishment of consumables or detection of faults. Additionally, placing the main control circuit board and gold fingers above the paper tray fully utilizes the upper space inside the casing, increasing the capacity for paper rolls, reducing the frequency of paper roll replacements, and making the overall structure more compact, thus contributing to the miniaturization of the device.

[0026] Reference Figures 1 to 6An embedded thermal printer includes a housing, a rubber roller 121, and a thermal sheet 119. The housing includes a base 11, a front cover 12, and a side cover 13. The thermal sheet 119 is disposed inside the base 11. A paper tray 116 is disposed inside the base 11, and a paper shaft 117 is disposed inside the paper tray 116. The paper shaft 117 extends in the horizontal left-right direction Y. A positioning hole 118 is provided at the end of the paper shaft 117. The rubber roller 121 is rotatably disposed on the front cover 12. The front cover 12 is connected to the front end of the base 11, and a paper outlet 10 is formed between the front cover 12 and the base 11. The side cover 13 is connected to the first side end of the base 11 and covers the outside of the paper tray 116. The thermal sheet 119 and the rubber roller 121 are opposite to each other and form a paper feeding channel. The paper feeding channel connects the paper tray 116 and the paper outlet 10. A positioning post 136 is provided in the middle of the side cover 13. When the side cover 13 is closed, the positioning post 136 engages with the positioning hole 118.

[0027] The housing is provided with assembly slides 112 and 131 on opposite sides in the horizontal left-right direction Y. Both assembly slides 112 and 131 extend in the horizontal front-back direction X. Assembly slides 112 and 131 are provided with loading openings 114 and 133 at their rear ends, respectively. Assembly slides 112 and 131 are provided with stop end faces 113 and 132 at their front ends, respectively.

[0028] Specifically, one assembly slide 131 is provided on the outer surface of the side cover 13, and the loading opening 133 of the assembly slide 131 on the side cover 13 is located at the rear end edge of the side cover 13. The base 11 is provided with a horizontal sidewall 111 on the opposite second side of the side cover 13. Another assembly slide 112 is provided on the outer surface of the horizontal sidewall 111, and the loading opening 114 of the assembly slide 112 on the base 11 is located at the rear end edge of the horizontal sidewall 111. The side cover 13 is provided with an observation window 134 along the horizontal front-back direction X, and a scale is provided below the observation window 134 for measuring the capacity of the remaining paper roll.

[0029] The base 11 has a through-hole 115 at its upper end. Assembly slides 112 and 131 are both located below the through-hole 115 and are at the same horizontal level. The width of the insertion opening 114 is greater than the width of the stop end face 113, and the width of the insertion opening 133 is greater than the width of the stop end face 132. The widths of the assembly slides 112 and 131 gradually decrease from the rear end to the front end.

[0030] The embedded thermal printer includes a main control circuit board 3, which is disposed inside the base 11. The main control circuit board 3 is arranged in a horizontal direction. The main control circuit board 3 and the connecting gold fingers 31 are both located above the paper tray 116.

The connecting gold finger 31 extends in the horizontal front-back direction X and has a notch in the middle for foolproof positioning. The connecting gold finger 31 protrudes through the rear end wall of the base 11.

[0031] The connecting plate 2 is a connection component for external devices, including but not limited to smart terminals or self-service terminals. The connecting plate 2 is equipped with a connecting female connector 21. When the embedded thermal printer is positioned into the self-service terminal or other external device via the slide groove, the connecting gold fingers 31 can be inserted into the corresponding interface of the connecting female connector 21. This allows the electrical and data communication connections to be automatically established simultaneously with the mechanical installation, completely eliminating the cumbersome steps of additional connection and fixing of data cables required in traditional methods, greatly simplifying the installation process. Furthermore, screws are passed through the fixing connection holes to connect with the corresponding fixing holes of the external device, ultimately forming a secure assembly.

[0032] As can be seen from the above, the horizontally arranged assembly slides on both sides of the housing and the insertion opening designed at the rear end allow the embedded thermal printer to be directly pushed into the mounting position of the external device in the horizontal direction, achieving precise alignment and initial fixation. In addition, the stop end face at the front end of the slide can effectively limit the insertion depth of the printer, ensuring proper installation. When maintenance or replacement is required, it can be pulled out in the reverse direction. The whole process does not require the use of cumbersome tools, greatly simplifying the operation process and improving assembly and maintenance efficiency.
