Description

Technical Field

[0001] The utility model relates to the technical field of artificial teeth processing, in particular to an artificial teeth carving machine. Background Art

[0002] As an important processing equipment, the precision and stability of the engraving machine directly determine the quality and production efficiency of dentures. However, the existing denture engraving machines have obvious technical bottlenecks in the transmission of electrical signals. Specifically, most of the denture engraving machines on the market do not have a special conduction structure to ensure the stable transmission of electrical signals, but rely on metal parts such as bearings and studs to achieve this function.

[0003] This design has significant drawbacks. First, metal parts are susceptible to wear and corrosion during long-term use, resulting in reduced stability in electrical signal transmission. Second, the contact area between metal parts is limited, and the position of the contact point is easily changed by mechanical vibration, further affecting the quality of electrical signal transmission. Finally, since metal parts themselves are not designed for electrical signal transmission, their electrical conductivity often cannot reach the optimal state, thus limiting the speed and accuracy of electrical signal transmission.

[0004] Due to the above problems, the existing denture engraving machines often cannot guarantee accuracy during the process of automatic calibration of spatial coordinates. When errors occur in the calibration of spatial coordinates, the denture may have positioning errors after being installed, which not only affects the processing quality of the denture, but also may lead to frequent shutdowns and adjustments during the production process, seriously reducing production efficiency. In addition, due to the lack of automatic calibration accuracy, operators need to spend more time and energy on manual adjustments, further increasing production costs and labor intensity.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] As an important processing equipment, the precision and stability of the engraving machine directly determine the quality and production efficiency of the denture. However, the existing denture engraving machine has obvious technical bottlenecks in the transmission of electrical signals. Specifically, most of the denture engraving machines on the market do not have a special conduction structure to ensure the stable transmission of electrical signals, but rely on metal parts such as bearings and studs to achieve this function. This design method has significant defects. First, metal parts are susceptible to wear and corrosion during long-term use, resulting in a decrease in the stability of electrical signal transmission. Secondly, the contact area between metal parts is limited, and the position of the contact point is easily changed due to mechanical vibration, which further affects the transmission quality of the electrical signal. Finally, since the metal parts themselves are not designed for electrical signal transmission, their electrical conductivity often cannot reach the optimal state, thereby limiting the speed and accuracy of electrical signal transmission. Due to the existence of the above problems, the existing denture engraving machine often cannot guarantee accuracy in the process of automatic calibration of spatial coordinates, and when errors occur in the calibration of spatial coordinates, the denture may have positioning errors after being loaded, which not only affects the processing quality of the denture, but also may cause frequent shutdowns and adjustments during the production process, seriously reducing production efficiency. In addition, due to the lack of automatic calibration accuracy, operators need to spend more time and energy on manual adjustments, further increasing production costs and labor intensity. Therefore, developing a denture engraving machine with a dedicated conduction structure to achieve smooth and stable transmission of electrical signals has become a technical problem that needs to be solved in the current denture processing field.

[0033] Based on this, this embodiment provides a denture engraving machine, please refer to Figure 1-2As shown, it includes: a calibration piece 110, a calibration rod 111, a conductive piece 113, a circuit board 112 and a wire 114, wherein the calibration piece 110 is used to calibrate the spatial coordinates of the engraving machine. During the processing of the denture, the installation position of the denture on the engraving machine needs to be calibrated to improve the processing accuracy of the denture and promote product quality; further, the calibration rod 111 is used to calibrate the calibration piece 110. The calibration piece 110 is calibrated in advance by using the calibration rod 111. If the calibration piece 110 is not calibrated and the denture is installed, it will cause the denture to Positioning errors occur, which further leads to a decrease in the processing accuracy of the denture; further, the conductive piece 113 is used to connect the calibration piece 110 and the circuit main board 112, the circuit main board 112 is used to send an electrical signal to the calibration rod 111, and the wire 114 is used to electrically connect the circuit main board 112 with the calibration rod 111 and the calibration piece 110 respectively; wherein, the calibration rod 111 is in contact with the calibration piece 110 so that the wire 114 forms a closed loop, so that the electrical signal is transmitted from the calibration rod 111 to the calibration piece 110 after passing through the conductive piece 113 and then transmitted back to the circuit main board 112 through the wire 114.

[0034] Preferably, the calibration rod 111 is clamped and moved by an external mechanical arm, thereby driving the calibration rod 111 to move. It can be understood that in this embodiment, the distance that the external mechanical arm drives the calibration rod 111 to move is calculated by the electrical signal sent by the circuit mainboard 112, and then the calibration result is fed back to the user by transmitting the calculation result to the user terminal. In addition, the adjustment value corresponding to the calculation result is derived through the preset algorithm of the user terminal, and the signal calculation coordinates and balance compensation values ​​that need to be adjusted for the calibration part 110 are fed back to the user; that is: the engraving machine automatically calibrates the spatial coordinates through the metal calibration disk 132 and the metal calibration rod 111; during calibration, the circuit mainboard 112 sends an electrical signal, and the coordinates and balance compensation values ​​are calculated according to the returned signal. If the conduction performance is poor or not conductive, it will affect the calculation result or even fail to calibrate.

[0035] According to the above scheme, it can be understood that in the conventional engraving machine which does not have the circuit board 112 and the wire 114 installed to transmit the electrical signal, and only uses metal parts such as bearings and studs to realize this function, the engraving machine uses the conventional metal transmission shaft to contact the conduction shaft to transmit the electrical signal. According to the foregoing, before the denture needs to be installed on the engraving machine for processing, the calibration piece 110 needs to be calibrated. When the calibration piece 110 is calibrated by using the calibration rod 111, the electrical signal is transmitted from the calibration rod 111 to the calibration piece 110, and then the electrical signal is transmitted through the conduction shaft connected to the calibration piece 110 and the metal transmission shaft. During the transmission process, this transmission method has problems due to the conventional electrical signal transmission method. The operation of the engraving machine will cause vibration and rotation of the metal transmission shaft, and these conditions will affect the contact between the conductive shaft and the metal transmission shaft, causing the conductive shaft and the metal transmission shaft to separate from each other, thereby causing the transmission of the electrical signal to be stuck and delayed. When the electrical signal is delayed, the calibration rod 111 and the calibration part 110 may be in contact with each other, but the electrical signal is not transmitted back to the circuit main board 112 through the wire 114 in time, causing the circuit main board 112 to control the calibration rod 111 to continue moving to further calibrate the calibration part 110. In this case, there will be errors in the positioning of the calibration part 110, which will affect the accuracy of subsequent denture processing.

[0036] According to the above scheme, it can be understood that this embodiment uses the circuit main board 112 to send electrical signals, and sets the conductive member 113 so that when the calibration rod 111 abuts against the calibration member 110, the electrical signal is transmitted into the calibration member 110 through the calibration rod 111, and then transmitted back to the circuit main board 112 through the conductive member 113 and the wire 114, replacing the traditional transmission structure through the conductive column 121 and the metal transmission column 134. The dedicated conductive parts and lines have good contact, ensuring the smooth transmission of electrical signals, avoiding the situation where the calibration rod 111 moves in error due to electrical signal delay or jamming, improving the calibration accuracy of the calibration member 110 for the denture, further improving the processing accuracy of the denture intelligent engraving machine after loading the denture, and improving the stability and durability of the intelligent engraving machine. In addition, the circuit main board 112 and the wire 114 are integrated with the inherent circuit of the engraving machine, and no additional installation is required, and the conductive line is directly connected to the circuit main board 112, without the need for intermediate switching, with low cost and good effect.

[0037] Preferably, the calibration member 110 is installed on the calibration bracket 115 and is located on one side of the conducting column 121, and the calibration member 110 is movable relative to the calibration bracket 115; further, the calibration member 110 includes an outer frame 131, a calibration disk 132 installed on the outer frame 131, and a bearing member 133, the bearing member 133 includes a transmission column 134, the transmission column 134 is connected to the conducting column 121, so that the conducting column 121 can rotate with the transmission column 134; and in one embodiment, the bearing member 133 also includes a bearing plate 135, the bearing plate 135 is installed between the calibration bracket 115 and the outer frame 131, and the calibration plate 132 can realize pivotal movement relative to the calibration bracket 115 through the bearing plate 135.

[0038] Preferably, the conductive member 113 includes a conductive column 121, a conductive sheet 122 and a conductive seat 123, the conductive seat 123 is installed on the calibration bracket 115, the conductive sheet 122 is installed on the conductive seat 123, one end of the conductive column 121 is abutted against the conductive sheet 122, and the other end is abutted against the calibration member 110; this structure is that: the calibration disk 132 is connected to the circuit main board 112 through the conductive column 121, the conductive sheet 122 and the conductive seat 123 to ensure stable conduction; the conduction principle in this embodiment is: the electrical signal emitted by the circuit main board 112 needs to form a stable closed loop to ensure the calibration accuracy. This structure forms a stable closed loop between the calibration disk 132 and the circuit main board 112 through three conductive parts, ensuring that the electrical signal is smoothly transmitted back to the circuit main board 112, thereby improving the calibration accuracy and thus improving the processing accuracy.

[0039] Preferably, a fixing screw hole 11a is provided on the conductive seat 123, and the denture engraving machine 100 also includes a fixing piece 116, and the fixing piece 116 passes through the fixing screw hole 11a and is fixed to the calibration bracket 115, thereby fixing the conductive seat 123 on the calibration bracket 115; and, in this embodiment, the wire 114 includes a first wire 141 and a second wire 142, one end of the first wire 141 is connected to the circuit main board 112, and the other end is connected to the calibration rod 111, one end of the second wire 142 is connected to the circuit main board 112, and the other end is connected to the fixing piece 116 installed in the fixing screw hole 11a; and, a connecting terminal 151 is provided at one end of the second wire 142 connected to the fixing piece 116, and the connecting terminal 151 is set to a "U"-shaped structure, and is connected to the fixing piece 116 through the connecting terminal 151 of the second wire 142, thereby facilitating the installation of the second wire 142, and the structure is firm and not easy to fall off.

[0040] According to the above scheme, it can be understood that in this embodiment, a plurality of coordinate points 161 are provided on the side of the calibration disk 132 facing the calibration rod 111, and the plurality of coordinate points 161 are arranged on the calibration disk 132. The calibration rod 111 is clamped and moved by an external robotic arm so that it can be inserted into any coordinate point 161 on the calibration disk 132, and all coordinate points 161 on the calibration disk 132 can be preset through the user terminal, so that when the calibration rod 111 is in contact with any coordinate point 161, the adjustment value corresponding to the calculation result can be derived, and the signal calculation coordinates and balance compensation value that need to be adjusted for the calibration component 110 can be fed back to the user.

[0041] In summary, the utility model provides a denture engraving machine, which uses a circuit mainboard to send electrical signals, and sets a conductive part so that when the calibration rod abuts against the calibration part, the electrical signal is transmitted into the calibration part through the calibration rod, and then transmitted back to the circuit mainboard through the conductive part and the wire, replacing the traditional transmission structure through the conductive column and the metal transmission column. The dedicated conductive parts and lines have good contact, ensuring the smooth transmission of electrical signals, avoiding errors in the movement of the calibration rod due to electrical signal delays or jams, improving the calibration accuracy of the calibration parts for the spatial coordinates of the engraving machine, further improving the processing accuracy of the denture intelligent engraving machine after loading the denture, and improving the stability and durability of the intelligent engraving machine. In addition, the circuit mainboard and the wires are integrated with the inherent circuits of the engraving machine, and no additional installation is required, and the conductive line is directly connected to the circuit mainboard, without the need for intermediate switching, with low cost and good effect.
