[0045] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0046] 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.

[0047] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or a solution that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0050] At present, etching machines include chemical etcher and electrolytic etcher. Among them, chemical etcher is a device that uses chemical solution to etch the workpiece through chemical reaction. Moreover, in order to improve the etching efficiency of the etcher on the workpiece, this type of etcher is also usually provided with a heating element to heat the chemical solution in the etcher.

[0051] However, the arrangement of the heating element makes it easy for the user to come into contact with the heating element and get burned when taking and placing the workpiece, which affects the safety of the etching machine. At the same time, the workpiece is also easy to collide with the heating element, which in turn causes the heating element to be easily damaged.

[0052] Therefore, based on the above considerations, in order to solve the problem that the current etching machine has relatively low safety and service life, the present application proposes a new type of etching machine. The etching machine innovatively provides a partition in the etching chamber of the machine body, so as to isolate the user's hands from the heating element through the partition, thereby avoiding burns to the heating element, and at the same time isolate the workpiece and the heating element, thereby preventing the workpiece from damaging the heating element.

[0053] Next, the structure of the etching machine proposed in this application is explained and described by an embodiment. In one embodiment of this application, please refer to Figure 1 and Figure 2 The etching machine 100 proposed in the present application includes a body 1, a partition 2 and a heating element 3. An etching chamber 11 is provided in the body 1; the partition 2 is provided in the etching chamber 11 and divides the etching chamber 11 into a first chamber 111 and a second chamber 113; the heating element 3 is provided in the first chamber 111.

[0054] The body 1 can be used to form an etching chamber 11, so as to accommodate a chemical solution through the etching chamber 11, thereby forming a processing space for etching a workpiece. Among them, the shape of the body 1 can be a rectangular parallelepiped, so that the shape of the body 1 is more regular, which is conducive to improving the convenience of its manufacture. Of course, the shape of the body 1 can also be a cube or a cylinder, etc., and the present application does not limit the shape of the body 1. In order to make the wall thickness of each part of the body 1 more uniform, the shape of the etching chamber 11 can be adaptively set following the shape of the body 1. For example: when the shape of the body 1 is set to a rectangular parallelepiped, the shape of the etching chamber 11 can also be set to a rectangular parallelepiped. In addition, the material of the body 1 can be a transparent material, such as an acrylic material, so that the situation inside the body 1 can be observed. Of course, the material of the mechanism can also be a non-transparent material, and the present application does not limit the material of the body 1.

[0055] The separator 2, as the name implies, is an object that can play a role of separation. Specifically, the separator 2 can separate the etching chamber 11 into a first cavity 111 and a second cavity 113, so that the etching chamber 11 can accommodate the heating element 3 through the first cavity 111, and accommodate the workpiece through the second cavity 113, thereby isolating the user's hands and the heating element 3 during the process of taking and placing the workpiece, and isolating the workpiece and the heating element 3. Among them, when the etching machine 100 is in a normal use and placement state, the etching machine 100 is defined to have an up and down direction, and the first cavity 111 and the second cavity 113 can be arranged in sequence from bottom to top as described below. Of course, the first cavity 111 and the second cavity 113 can also be arranged side by side in the horizontal direction. In addition, the first cavity 111 and the second cavity 113 can be connected. Of course, the first cavity 111 and the second cavity 113 can also be arranged in isolation. At this time, the chemical solution can be accommodated in the second cavity 113. In order to realize that the heating element 3 located in the first cavity 111 can heat the chemical solution located in the second cavity 113, the partition 2 can have thermal conductivity to realize the transfer of heat generated by the heating element 3. In addition, the partition 2 can be made of the same material as the body 1, such as acrylic material, so that it is transparent and convenient for observing the inside of the body 1, and at the same time it will not react with the chemical solution. Of course, the partition 2 can also be made of other materials as long as it is guaranteed not to react with the chemical solution. The present application does not limit the material of the partition 2. In addition, the partition 2 can be a cover body structure formed by the combination of the partition 21 and the support part 23 as described below, of course, it can also be a plate structure including only the partition 21, or a cylindrical structure. The present application does not limit the structural type and shape of the partition 2.

[0056] The heating element 3 can be used to generate heat to heat the chemical solution in the etching chamber 11, thereby improving the reaction efficiency and improving the etching efficiency of the workpiece by the etching machine 100. The heating element 3 can be an electric heating tube so that it has a larger heating power and is conducive to improving the heating efficiency of the chemical solution by the heating element 3. Of course, the heating element 3 can also be an electric heating wire, and the specific type of the heating element 3 is not limited in this application.

[0057] The etching machine 100 of the technical solution of the present application has a partition 2 disposed in the etching chamber 11 of the machine body 1, through which the etching chamber 11 can be divided into a first cavity 111 and a second cavity 113, and the heating element 3 is disposed in the first cavity 111. When the etching machine 100 is used later, the workpiece to be etched can be placed in the second cavity 113 of the etching chamber 11 for etching. At this time, since the workpiece and the heating element 3 are respectively located in the second cavity 113 and the first cavity 111 of the etching chamber 11, the user will not come into contact with the heating element 3 when taking and placing the workpiece, resulting in a scalding accident, which is beneficial to improving the safety of the use of the etching machine 100. At the same time, the workpiece will not cause damage to the heating element 3, which is also beneficial to improving the service life of the etching machine 100.

[0058] Please refer to Figure 2 and Figure 3 In one embodiment of the present application, the etching machine 100 is defined to have an up-down direction, and the first chamber 111 and the second chamber 113 are sequentially arranged from bottom to top.

[0059] The etching machine 100 has an up-down direction, which is defined when the etching machine 100 is in a normal use state. The first cavity 111 and the second cavity 113 are arranged from bottom to top, which means that the first cavity 111 is located below the second cavity 113 .

[0060] In this embodiment, the first cavity 111 is disposed below the second cavity 113, so that the heating element 3 is located at the bottom of the etching cavity 11. At this time, the heating element 3 can be fully accommodated in the chemical solution in the etching cavity 11, which can ensure the contact area between the heating element 3 and the chemical solution, thereby facilitating the improvement of the heating effect of the heating element 3 on the chemical solution.

[0061] Please refer to Figures 3 to 5 In one embodiment of the present application, the partition 2 includes a partition portion 21 and a support portion 23. The partition portion 21 and the bottom wall of the etching chamber 11 are arranged relatively spaced apart, and the etching chamber 11 is divided into a first cavity 111 and a second cavity 113; the support portion 23 is connected to the partition portion 21, and the support portion 23 is located between the partition portion 21 and the bottom wall of the etching chamber 11, and abuts against the bottom wall of the etching chamber 11.

[0062] The partition 21 can be used as the main structure of the partition 2 to achieve the partitioning effect of the partition 2 on the etching chamber 11. The partition plate can be a plate structure (including a flat plate structure and an arc plate structure). The support portion 23 can abut against the bottom wall of the etching chamber 11 and support the partition 21. The support portion 23 can be a plate structure, and of course it can also be a column structure (including a cylindrical structure and a prismatic structure).

[0063] In this embodiment, the separator 2 is configured to include a separator 21 and a support portion 23, so that the separator 2 can be directly and stably limited in the etching chamber 11 by the support portion 23, and there is no need to further set a structure on the chamber wall of the etching chamber 11 to support and limit the separator 2, so as to simplify the structure of the etching chamber 11 and facilitate its processing and forming. Of course, it should be noted that in other embodiments, the separator 21 and the support portion 23 can be used together to separate the etching chamber 11 into the first cavity 111 and the second cavity 113.

[0064] Please refer to Figure 5 In one embodiment of the present application, the partition portion 21 and the support portion 23 are both flat plate structures.

[0065] In this embodiment, the partition 21 and the support 23 are both configured as flat plate structures, which can make the structures of both relatively simple, thereby facilitating the manufacturing of the partition 2. On the other hand, the support 23 can also have a larger area, thereby facilitating the overall strength of the partition 2 and prolonging its service life.

[0066] In one embodiment of the present application, the partition portion 21 and the support portion 23 are connected by bonding.

[0067] In this embodiment, the partition 21 and the support portion 23 are arranged to be bonded, that is, the partition 21 and the support portion 23 can be processed independently first, and then assembled into a whole by splicing. The split partition 21 and the support portion 23 are integrated with the partition 2, and the structure is simpler and convenient for processing and molding. Therefore, the partition 21 and the support portion 23 are arranged separately, which can also improve the convenience of manufacturing the partition 2. Furthermore, the partition 21 and the support portion 23 are arranged to be bonded, so that there is no need to set a connecting structure on the partition 21 and the support portion 23, which can simplify the structure of the two. At the same time, the bonding connection also has the advantages of stable and simple connection, which is conducive to improving the stability of the connection between the partition 21 and the support portion 23 while improving the convenience of the connection between the partition 21 and the support portion 23.

[0068] Please refer to Figure 5In one embodiment of the present application, the number of the supporting portions 23 is at least two, and two of the supporting portions 23 are respectively connected to opposite sides of the partition portion 21 .

[0069] The number of the supporting parts 23 is at least two, that is, the number of the supporting parts 23 can be two, and of course, it can also be more. The two supporting parts 23 can be arranged at a relative interval and located at two opposite sides of the partition part 21.

[0070] In this embodiment, at least two supporting portions 23 are arranged in opposite directions, so that the partition 21 can be supported on both sides of the partition 21, thereby facilitating the stability of the partition 2 in the etching chamber 11. In order to take into account the stability of the support portion 23 supporting the partition 21 and the complexity of the structure of the partition 2, the number of the supporting portions 23 can be set to two. At this time, the partition 21 and the two supporting portions 23 can be combined to form a U-shaped structure.

[0071] Please refer to Figure 2 In one embodiment of the present application, the first cavity 111 is extended along a horizontal direction, and the heating element 3 is extended along the extension direction of the first cavity 111 .

[0072] In this embodiment, the first cavity 111 and the heating element 3 are both extended in the horizontal direction, so that the first cavity 111 does not need to be set higher due to the long length of the heating element 3. That is, such a setting can reduce the overall height of the etching machine 100, and thus when the etching machine 100 is used, it can improve the user's access to the workpiece. Among them, when there are two supporting parts 23 in the partition 2 as described above, the two supporting parts 23 can be distributed in sequence along the first horizontal direction, and the first cavity 111 and the heating element 3 can be extended in a second horizontal direction perpendicular to the first horizontal direction, so that the supporting part 23 will not interfere with the setting of the heating element 3.

[0073] Please refer to Figure 2 and Figure 5 In one embodiment of the present application, the partition 2 is provided with a connecting hole 211 , and the connecting hole 211 connects the first cavity 111 and the second cavity 113 .

[0074] The connecting hole 211 passes through the two opposite surfaces of the separator 2, thereby realizing the connection between the first cavity 111 and the second cavity 113. The shape of the connecting hole 211 can be circular, or square or rectangular. The number of the connecting holes 211 can be one, two or more. When the number of the connecting holes 211 is multiple, the multiple connecting holes 211 can be distributed in a rectangular array to improve the regularity of the distribution of the connecting holes 211, thereby improving the convenience of manufacturing the separator 2. In addition, when the separator 2 includes a partition portion 21 and a support portion 23 as described above, the connecting hole 211 can be set on the partition portion 21.

[0075] In this embodiment, the first cavity 111 and the second cavity 113 are connected by providing a connecting hole 211 on the partition 2, and the chemical solution can enter the first cavity 111 through the connecting hole 211. At this time, the heating element 3 located in the first cavity 111 can be in direct contact with the chemical solution in the etching cavity 11, which is beneficial to improve the heating effect of the chemical solution.

[0076] Please refer to Figure 3 In one embodiment of the present application, the etching machine 100 further includes a flow stirring mechanism 4 , which is disposed in the first chamber 111 .

[0077] The stirring mechanism 4, as the name implies, can stir the chemical solution in the etching chamber 11 to accelerate the reaction rate of the chemical solution. The stirring mechanism 4 can include an outlet pipe 41 as described below, or can be a stirring impeller. The present application does not limit the structural type of the stirring mechanism 4.

[0078] In this embodiment, the flow stirring mechanism 4 is provided so that the chemical solution can be stirred, thereby accelerating the reaction rate of the chemical solution, so as to further improve the etching efficiency of the workpiece by the etching machine 100. Similarly, the flow stirring mechanism 4 is provided in the first cavity 111, so that the flow stirring mechanism 4 can also be isolated by the partition 2 described above.

[0079] Please refer to Figure 3 ,as well as Figures 6 to 8 In one embodiment of the present application, the flow stirring mechanism 4 includes an air outlet pipe 41, which is arranged in the first cavity 111 and is arranged side by side with the heating element 3; the air outlet pipe 41 is provided with at least two air outlet holes 411, and the at least two air outlet holes 411 are arranged in sequence along the extension direction of the air outlet pipe 41.

[0080] The gas outlet pipe 41 may be connected to an air pump, so when the air pump is working, the air flow may be delivered to the gas outlet pipe 41. The gas outlet pipe 41 is provided with a gas outlet hole 411, and then the gas is delivered to the first cavity 111 through the gas outlet hole 411. At this time, the gas delivered through the gas outlet hole 411 can stir the chemical solution in the etching chamber 11.

[0081] In this embodiment, the flow stirring mechanism 4 is configured to include an air outlet pipe 41 , so that the structure of the air outlet pipe 41 is relatively simple and the volume can be relatively small, thereby facilitating the manufacturing of the flow stirring mechanism 4 .

[0082] Please refer to Figures 6 to 8 In one embodiment of the present application, the etching machine 100 further includes a mounting carrier 5 , and the heating element 3 and the air outlet pipe 41 are both mounted on the mounting carrier 5 .

[0083] The mounting carrier 5 can be used to provide a mounting position to mount the heating element 3 and the air outlet pipe 41, so that the parts can be integrated into a whole. The mounting carrier 5 can include a first carrier 51 and a second carrier 53 as described below, or can also include only one of the first carrier 51 and the second carrier 53.

[0084] In this embodiment, the heating element 3 and the air outlet pipe 41 are both mounted on the mounting carrier 5, so that the heating element 3 and the air outlet pipe 41 can be integrated, which facilitates the one-time installation of the integrated combination of the heating element 3 and the air outlet pipe 41 on the machine body 1. At the same time, it is also convenient to arrange the wiring of the heating element 3 and the air pump connected to the air outlet pipe 41, thereby improving the regularity of the wiring harness.

[0085] Please refer to Figure 3 , Figure 4 , Figure 6 as well as Figure 8 In one embodiment of the present application, the body 1 is further provided with an installation cavity 13, the installation cavity 13 and the etching cavity 11 are isolated, and parts of the heating element 3 and parts of the air outlet pipe 41 pass through the body 1 and extend into the installation cavity 13; the installation carrier 5 includes a first carrier 51 and a second carrier 53, the first carrier 51 is arranged in the first cavity 111, and the heating element 3 and the air outlet pipe 41 located in the first cavity 111 are both installed on the first carrier 51; the second carrier 53 is arranged in the installation cavity 13, and the heating element 3 and the air outlet pipe 41 located in the installation cavity 13 are both installed on the second carrier 53.

[0086] The installation cavity 13 can be used to install and accommodate a portion of the heating element 3, a portion of the air outlet pipe 41, and an air outlet pump connected to the air outlet pipe 41. The installation cavity 13 and the etching cavity 11 can be arranged side by side in the horizontal direction. In addition, at least one of the first carrier 51 and the second carrier 53 in the installation carrier 5 is connected to the body 1.

[0087] In this embodiment, the heating element 3 and the air outlet pipe 41 are partially arranged in the first cavity 111, and the other part is arranged in the installation cavity 13, so that the end of the heating element 3 for electrical connection and the end of the air outlet pipe 41 for connecting the air pump can be located in the installation cavity 13, so as to avoid the chemical solution in the etching cavity 11 from affecting the end of the heating element 3 for electrical connection and the end of the air outlet pipe 41 for connecting the air pump. Furthermore, the installation carrier 5 is arranged to include a first carrier 51 and a second carrier 53, so that the opposite ends of the heating element 3 and the air outlet pipe 41 can be installed and limited, which is conducive to improving the stability of the installation of the heating element 3 and the air outlet pipe 41.

[0088] Please refer to Figure 6 and Figure 7 In one embodiment of the present application, the etching machine 100 also includes a temperature sensor 6, which is arranged side by side with the heating element 3 and the air outlet pipe 41; one end of the temperature sensor 6 is located in the installation cavity 13 and is installed on the second carrier 53, and the other end passes through the body 1 and extends into the first cavity 111.

[0089] In this embodiment, the temperature of the chemical solution in the etching chamber 11 can be detected by the temperature sensor 6, so as to understand the heating result of the chemical solution by the heating element 3. One end of the temperature sensor 6 is arranged in the first cavity 111, and the other end is mounted on the second carrier 53, so that the temperature sensor 6 can be integrated with the heating element 3 and the air outlet pipe 41, thereby facilitating the wiring arrangement of the temperature sensor 6. Furthermore, the body 1 can also be provided with a display screen, so as to intuitively display the temperature value detected by the temperature sensor 6 through the display screen for convenient observation by users.

[0090] Please refer to Figure 6 In one embodiment of the present application, the etching machine 100 further includes a controller 7 , which is disposed in the installation cavity 13 , and the heating element 3 in the installation cavity 13 is electrically connected to the controller 7 .

[0091] In the present embodiment, the setting of the controller 7 facilitates the automatic control of the operation of the heating element 3. For example, the controller 7 can also be electrically connected to the temperature sensor 6 introduced above. When the temperature sensor 6 detects that the chemical solution is heated to the required temperature, the heating element 3 can be controlled to be turned off by the controller 7. After that, when the temperature sensor 6 detects that the temperature of the chemical solution has dropped, the heating element 3 can be controlled to be turned on by the controller 7 to heat the chemical solution to the required temperature again. Such a cyclic reciprocating control can realize the heating control of the chemical solution at a preset target temperature or close to the preset target temperature, so that the chemical solution reacts stably and efficiently at the target temperature to realize the stable and efficient etching of the workpiece by the etching machine 100. In addition, it should be noted that the controller 7 can also be electrically connected to the air pump connected to the air outlet pipe 41 introduced above to realize automatic control of the operation of the air pump.

[0092] Please refer to Figure 1 In one embodiment of the present application, the etching machine 100 also includes a timing adjustment mechanism 8, and the timing adjustment mechanism 8 is electrically connected to the controller 7.

[0093] In the present embodiment, the timing mechanism 8 can be used to adjust the working time of the etcher 100, so as to realize the automatic timing work of the etcher 100. For example: when the working time of the etcher 100 is 5 minutes by the timing mechanism 8, the controller 7 can control the etcher 100 to work for 5 minutes. When it reaches 5 minutes, the controller 7 controls the etcher 100 to shut down (that is, the heating element 3 introduced above, the air pump connected to the air outlet pipe 41, and the temperature sensor 6 are turned off). In this way, there is no need for the user to pay attention to the working state of the timing machine at all times, which is conducive to improving the convenience of using the etcher 100. Among them, the timing mechanism 8 can be an adjustment switch 81 as described below, of course, it can also be in the form of a keyboard, or in the form of a touch screen. The present application does not limit the structural type of the timing mechanism 8. In addition, the preset working time adjusted by the timing mechanism 8 to the etcher 100 can be adaptively set as needed, which can be any time such as 5 minutes, 10 minutes or 15 minutes.

[0094] Please refer to Figure 1 In one embodiment of the present application, the time adjustment mechanism 8 is an adjustment switch 81, which includes a switch body and an adjustment key. The switch body is arranged on the body 1, and the switch body is formed with at least two time positions; the adjustment key is movably arranged on the switch body and can be moved to each time position.

[0095] In the present embodiment, the switch body of the adjustment switch 81 has a time gear, for example, a 5-minute gear and a 10-minute gear, etc. Afterwards, when the adjustment key is rotated or moved to the 5-minute gear, the controller 7 can receive the first signal input by the adjustment switch 81, thereby controlling the etching machine 100 to work for 5 minutes. When the adjustment key is rotated or moved to the 10-minute gear, the controller 7 can receive the second signal input by the adjustment switch 81, thereby controlling the etching machine 100 to work for 10 minutes. At this time, the time adjustment mechanism 8 is set in the form of the adjustment switch 81, so that the structure of the time adjustment mechanism 8 is relatively simple, which is conducive to improving the convenience of its manufacture. At the same time, it also makes the time adjustment process relatively simple, and only the adjustment key needs to be rotated or slid, which is conducive to further improving the convenience of using the etching machine 100.

[0096] Please combine Figures 9 to 11 In one embodiment of the present application, the machine body 1 is further provided with a take-in / take-out port 15 , which is connected to the second cavity 113 ; the etching machine 100 also includes a carrier 9 , which is insertable and retractable in the second cavity 113 through the take-in / take-out port 15 .

[0097] The access port 15 can be used to place the workpiece in the etching chamber 11, or to take the workpiece out of the etching chamber 11. The access port 15 can be arranged on the upper surface of the body 1 as described below, or it can be arranged on the side surface of the body 1. The present application does not limit the location of the access port 15.

Moreover, the carrier 9 can be placed in the etching chamber 11 through the access port 15, or it can be taken out of the etching chamber 11. The carrier 9 can be a grid structure formed by a combination of multiple rods, or it can be a mesh structure with multiple openings.

[0098] In this embodiment, the sample carrier 9 can be used to carry the workpiece. After the workpiece is etched, the sample carrier 9 can be removed to remove the workpiece. Since the sample carrier 9 is relatively large, it can be easily exposed and held, which is conducive to improving the convenience of removing the workpiece.

[0099] Please combine Figures 9 to 11 In one embodiment of the present application, the etching machine 100 is defined to have an up and down direction, and the pick-up and drop-out port 15 is arranged on the upper surface of the body 1; the carrier 9 includes a holding portion 91 and a bearing portion 93, the holding portion 91 can be abutted and hung on the surface of the body 1 where the pick-up and drop-out port 15 is formed, and the bearing portion 93 is connected to the holding portion 91 and is located below the holding portion 91.

[0100] In this embodiment, the carrier 9 is configured to include a gripping portion 91 and a bearing portion 93, so that the gripping portion 91 can be conveniently abutted and hung on the upper surface of the body 1, that is, exposed at the upper end of the body 1, so as to facilitate the user to hold and take it. The bearing portion 93 can be used to carry the workpiece so that the workpiece is immersed in the chemical solution for etching. Among them, the gripping portion 91 and the bearing portion 93 can both be a rod structure, and of course can also be a plate structure. The present application does not limit the structural type and shape of the gripping portion 91 and the bearing portion 93.

[0101] Please refer to Fig.10 and Fig.11 In one embodiment of the present application, the gripping portion 91 includes an enclosing rod 911 and a connecting rod 915. The number of the enclosing rods 911 is at least two, and the two enclosing rods 911 are both enclosed to form a gripping hole 913 and are relatively spaced apart in the horizontal direction. The enclosing rods 911 can be abutted and hung on the surface of the body 1 where the access port 15 is formed; one end of the connecting rod 915 is connected to one of the two enclosing rods 911, and the other end is connected to the other of the two enclosing rods 911.

[0102] The enclosing rod 911 can be used to enclose a gripping hole 913 for the user to hold. The enclosing rod 911 can enclose a triangular gripping hole 913, and of course, it can also be enclosed to form a rectangular gripping hole 913. The present application does not limit the specific shape of the gripping hole 913 enclosed by the enclosing rod 911. The number of the enclosing rods 911 can be at least two, so that the two hands of the user can hold them respectively. In addition, the cross-section of the enclosing rod 911 can be circular, so that the enclosing rod 911 forms a smooth side surface, thereby improving the comfort of the user holding it. Of course, the cross-section of the enclosing rod 911 can also be rectangular or square, etc., which is not limited in the present application. The connecting rod 915 can be used to connect at least two enclosing rods 911, so that the gripping portion 91 can form a whole and improve the overall strength of the gripping portion 91. In addition, the cross section of the connecting rod 915 can be circular, or rectangular or square, etc., and the present application does not limit this. In addition, the number of connecting rods 915 can be two, and the arrangement direction of the two connecting rods 915 is perpendicular to the arrangement direction of the two enclosing rods 911, so as to further improve the stability of the connection of at least two enclosing rods 911.

[0103] In this embodiment, the holding portion 91 is configured to include an enclosing rod 911 and a connecting rod 915, so that the holding portion 91 can be better formed with a holding hole 913 and have a certain strength, thereby facilitating the user to carry out portable and stable picking and placing of the carrier 9 and the workpiece through the holding portion 91.

[0104] Please refer to Fig.10 and Fig.11 In one embodiment of the present application, the bearing portion 93 includes a plurality of bending rods 931 , and the plurality of bending rods 931 are arranged side by side and spaced apart in a horizontal direction, and both ends of each bending rod 931 are connected to the gripping portion 91 .

[0105] The bending rod 931 can form a U-shaped structure, and the two ends thereof enclosed to form an opening can be connected to the gripping portion 91. When the gripping portion 91 includes the enclosing rod 911 and the connecting rod 915 as described above, the two ends of the bending rod 931 located at the end to form an opening can be connected to the enclosing rod 911, and the two ends of the remaining bending rods 931 to form an opening can be connected to the two connecting rods 915.

[0106] In this embodiment, the bearing portion 93 is configured to include a plurality of bent rods 931 , so that the bearing portion 93 can be a relatively simple rod structure and the structure of the bearing portion 93 can be simplified, thereby facilitating the manufacturing of the bearing portion 93 .

[0107] Please refer to Fig.10 and Fig.11 In one embodiment of the present application, the bearing portion 93 further includes a limiting rod 933, which is extended in the up-down direction, and the opposite ends of the limiting rod 933 are respectively connected to the gripping portion 91 and the bending rod 931 at the end.

[0108] In this embodiment, the setting of the limiting rod 933 can limit the end of the load-bearing portion 93 in the arrangement direction of the multiple bending rods 931, so as to reduce the possibility of the product located in the load-bearing portion 93 sliding out from the bending rods 931 at the end, thereby helping to improve the stability of the load-bearing portion 93 in accommodating and carrying the workpiece.

[0109] Please refer to Fig.10 and Fig.11 In one embodiment of the present application, the bearing portion 93 further includes a reinforcing rod 935 , and the reinforcing rod 935 connects at least two bending rods 931 .

[0110] The reinforcing rod 935 can be used to connect at least two bending rods 931 to form a whole. The reinforcing rod 935 can be extended in a linear direction and connect the ends of the plurality of bending rods 931 away from the gripping portion 91. Of course, the reinforcing rod 935 can also be an annular structure and surround and connect the plurality of bending rods 931.

[0111] In this embodiment, the reinforcing rod 935 can play a role in connecting and reinforcing at least two bending rods 931, thereby facilitating improving the overall strength of the bearing portion 93, so as to further improve the stability of the bearing portion 93 in accommodating and bearing the workpiece.

[0112] In one embodiment of the present application, the carrier 9 can be made of metal material to have good strength. However, in order to prevent the carrier 9 from reacting with the chemical solution in the etching chamber 11, an anti-corrosion glue can be applied on the outside of the carrier 9.

[0113] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the etching machine 100 further includes a covering member 19 , which can open and close the access port 15 .

[0114] The cover 19 can be used to cover the access opening 15 of the body 1, thereby sealing the etching chamber 11. The cover 19 may not be connected to the body 1, that is, the cover 19 can be directly placed on the body 1. Of course, the cover 19 can also be detachably connected to the body 1 by means of a snap connection or a magnetic connection. Alternatively, the cover 19 can be rotatably or slidably connected to the body 1, so that the access opening 15 can be opened and closed by rotating or sliding the cover 19.

[0115] In this embodiment, the cover 19 is provided so that when the etching machine 100 is not in use, the chemical solution stored in the etching chamber 11 can be sealed and preserved, thereby preventing foreign matter from contaminating the chemical solution.

[0116] Please refer to Figure 1 In one embodiment of the present application, the body 1 is made of a transparent material, and a liquid level line 17 is provided on the outer surface of the body 1 .

[0117] The liquid level line 17 can also be said to be an identification line of the volume of the chemical solution, so that when the chemical solution in the etching chamber 11 is added to the corresponding identification line, it means that the chemical solution in the etching chamber 11 has reached the volume corresponding to the liquid level line 17. Among them, there can be one liquid level line 17, and of course, there can also be two or more.

[0118] In this embodiment, the setting of the liquid level line 17 can provide a more intuitive display of the volume of the chemical solution in the etching chamber 11, so that the user can understand the volume of the chemical solution in the etching chamber 11. At this time, the constant temperature heating achieved by the controller 7 and the temperature sensor 6 described above can keep the volume and temperature of the chemical solution constant when using the etching machine 100, and the concentration of the chemical solution can also be kept constant by pre-adjusting. That is, several variables that affect the etching time: the volume of the chemical solution, the temperature of the chemical solution, and the concentration of the chemical solution can all be kept constant at preset values. At this time, the parameter table 16 of the area size of the workpiece and the corresponding recommended etching time can be attached to the machine body 1, so that the user can refer to the parameter table 16 to more accurately and quickly determine the etching time required for the workpiece. After that, the working time of the etching machine 100 is adjusted by the timing mechanism 8 described above to realize the timing work of the etching machine 100, thereby further improving the convenience of using the etching machine 100.

[0119] In one embodiment of the present application, the etching machine 100 may also include a buzzer so that when the etching machine 100 reaches the working time adjusted by the timing mechanism 8, a buzzer can be sounded to remind the user that the etching work is completed.

[0120] In one embodiment of the present application, the workflow of the etching machine 100 proposed in the present application can be: add a pre-configured chemical solution into the etching chamber 11, and add the chemical solution to the liquid level line 17; then the workpiece to be etched can be placed on the carrier 9; then the working time of the etching machine 100 can be adjusted by the timing mechanism 8 with reference to the area size of the workpiece on the body 1 and the corresponding parameter table 16 of the recommended etching time; then the carrier 9 can be immersed in the chemical solution in the etching chamber 11; then the power switch of the etching machine 100 is turned on, and the etching machine 100 starts to work (that is, the temperature sensor 6 detects the temperature; the heating element 3 heats the chemical solution to a preset temperature and performs constant temperature heating; the air pump connected to the air outlet pipe 41 supplies air to the etching chamber 11). After that, when the etching machine 100 reaches the working time adjusted by the timing mechanism 8, the buzzer can sound a prompt, the timing mechanism 8 returns to zero, and the etching machine 100 stops working. Then, the user takes out the carrier 9 to take out the workpiece. Finally, the user can seal the access opening 15 of the body 1 through the cover 19 to prevent foreign matter from contaminating the chemical solution, so as to effectively use the chemical solution again later.
