Description

Technical Field

[0001] This utility model relates to the field of cash register technology, and in particular to a cash register and scale with excellent anti-static capability and easy maintenance. Background Technology

[0002] With the widespread adoption of mobile payments, desktop cash registers with barcode scanning modules and cash register scales integrated with electronic scales have become widely used in many settings, such as large supermarkets, restaurants, and retail stores like cake shops, butcher shops, fruit shops, and dry goods stores that manage individual items. These locations typically have desktop cash registers or cash register scales at the checkout counter. For desktop cash registers, due to factors such as simplified operation for cashiers, improved user experience, and the trend towards self-checkout, current cash register devices are becoming increasingly feature-rich, integrating more and more electronic components. For example, in addition to barcode scanners, they now include receipt printers and displays that allow both cashiers and customers to view product information.

[0003] The increasing number of electronic components makes static electricity (STO) a significant risk factor for POS equipment malfunctions. For example, it can directly damage electronic components; STO attracts dust and impurities from the air, reducing the insulation resistance of components and shortening their lifespan; even if STO doesn't directly damage components, it can degrade their performance, such as increasing noise, reducing sensitivity (e.g., touchscreen sensitivity), and altering response time. Therefore, special STO protection is needed for existing multi-functional POS equipment such as cash registers and scales. Simultaneously, easier equipment maintenance is required, minimizing disassembly work during repairs. Furthermore, as cash registers become more multifunctional, they can connect to more external devices, requiring multiple interfaces and increasing the number of cables. Besides ensuring effective STO, the increasing number of cables can negatively impact the performance of barcode scanners. Therefore, neat cable management and ease of use are essential.

[0026] Combined with reference Figures 1-6 As shown, an embodiment of the present invention provides a cash register with excellent anti-static capabilities and easy maintenance, including a main frame 1, a camera 2, a display device 3, a main board 302, and a base 5. The main frame 1 includes a housing 11 and an aluminum alloy support frame 10 disposed inside the housing 11. The display device 3 is connected and installed at the top of the aluminum alloy support frame 10, and the base 5 is connected to the bottom of the aluminum alloy support frame 10. A mounting part 100 is provided at the top of the aluminum alloy support frame 10, and a fixing part 12 is provided on the mounting part 100. The display device 3 includes a rear cover plate 300 and a metal fixing plate 301 located inside the rear cover plate 300. The metal fixing plate 301 is fixedly connected to the main body of the display device 3 and corresponds to the position of the main board 302 of the display device. The metal fixing plate 301 covers at least part of the main board 302. The metal fixing plate 301 is connected to the fixing part 12 through a connecting fixing plate 6, thereby fixing the display device 3 to the aluminum alloy support frame 10. The connecting fixing plate 6 is made of metal. In this way, the mainboard of the cash register is fixedly connected to the metal fixing plate 301. The metal fixing plate 301 is connected to the aluminum alloy support frame 10 through the adapter fixing plate 6, which can form a smooth static discharge channel for the electronic components of the cash register, giving the cash register excellent anti-static capability.

[0027] In a preferred embodiment, such as Figure 3 , Figure 4 As shown, the display device 3 includes a first display device 31 and a second display device 32, which face the cashier and the customer respectively. Correspondingly, the fixing part 12 at the top of the aluminum alloy support frame 10 is also provided with a first fixing part 121 and a second fixing part 122, which are used to fix the first display device 31 and the second display device 32 respectively.

[0028] In a preferred embodiment, such as Figure 3 , Figure 4As shown, a protrusion 310 is provided in the middle of the rear cover frame 311 of at least one display device, such as the first display device 31 facing the cashier. The rear cover plate 300 is fixedly installed with the protrusion 310, and the metal fixing plate 301 is disposed inside the protrusion 310. At least one cable interface 303 (such as a USB interface) is provided on the left and / or right sides of the protrusion 310. Since the connection cable of the external device usually has a ferrite core, placing the cable interface on the left and right sides provides more space for insertion and removal of the cable when connecting the external device cable to the cable interface 303, compared to placing the cable interface on the bottom side. This avoids interference between the ferrite core on the cable and the camera or printing device installed on the main unit frame 1. Furthermore, side routing allows for easy cable management through the cable tray 123 at the top of the aluminum alloy support frame 10, preventing external cables from interfering with the normal operation of the camera or printing device on the cash register. In a preferred embodiment, the metal casing of the cable interface on the motherboard, such as the USB interface or ribbon cable connector, abuts against the metal mounting plate, or conductive foam (not shown) is attached to the metal mounting plate 301 at the position corresponding to the cable interface. The conductive foam is attached to the cable interface. In this way, the static electricity generated by the cash register device, including external devices, during operation, such as the static electricity generated by the cashier during touch screen operation or the static electricity generated when plugging and unplugging external devices, can be quickly grounded through the metal parts, providing the device with excellent electrostatic protection capabilities.

[0029] Next refer to Figure 5 The metal fixing plate 301 is provided with multiple hollowed-out parts 3011, 3012, 3013, etc. Some of the hollowed-out parts correspond to key electronic components on the motherboard 302, such as memory modules, wireless network cards, cable connectors, hard drives, etc., while the other hollowed-out parts serve as heat dissipation holes to help the motherboard dissipate heat. The rear cover plate 300 is detachably installed at the protrusion 310 of the display device 3, for example, by snapping it to the protrusion. When the motherboard needs to be inspected and repaired, only the rear cover plate 300 needs to be removed to inspect and repair the internal motherboard 302 without disassembling more parts, thus simplifying the inspection and repair operation.

[0030] like Figure 2 , Figure 4As shown, the aluminum alloy support frame 10 and the fixing part 12 are fixedly connected by screws or riveting; the fixing part 12 is fixedly connected to the adapter fixing plate 6, or the two are rotatably connected, such as by a pin, so that the angle of the display device 3 can be easily adjusted; the adapter fixing plate 6 and the metal fixing plate 301 are fixed by screws or welding, or the two are integrally formed. In a preferred embodiment, a connecting boss 304 is provided at the connection between the adapter fixing plate 6 and the metal fixing plate 301. The connecting boss 304 is fixed to the metal fixing plate 301, and the adapter fixing plate 6 is fixed on the connecting boss 304. In this way, the fixing structure strength of the display device can be improved, and the deformation of the metal fixing plate 301 can be prevented from damaging the electronic components on the circuit board below.

[0031] like Figure 2 , Figure 3 As shown, a top cover 13 is installed on the top of the aluminum alloy support frame 10. The top cover 13 and the housing 11 together cover the aluminum alloy support frame 10 of the cash register to prevent dust from falling in, while also ensuring the overall clean and beautiful appearance of the cash register. A bottom support part 14 is installed at the bottom of the aluminum alloy support frame 10. The bottom support part 14 can be adjusted in height to maintain the stability of the cash register when placed on the counter.

[0032] In another embodiment, the base 5 includes a metal base plate that is connected and fixed to or integrally formed with the aluminum alloy support frame 10, and is covered with a plastic cover plate, which can not only ensure the structural strength of the cash register, but also facilitate the rapid discharge of static electricity.

[0033] like Figure 1 As shown, the cash register also includes a receipt printer 7, which is mounted on the main frame 1 and fixed to the aluminum alloy support frame 10; the camera 2 is located below the display device 3 on one side of the electronic scale, that is, on the cashier's side, and is used to take pictures of items for image recognition to improve the efficiency of item settlement.

[0034] like Figure 7 As shown, this utility model also proposes a cash register scale 8, which includes the cash register as described above and an electronic scale 8 used in conjunction with the cash register.
