Description

TECHNICAL FIELD

[0001] The utility model relates to high -end equipment manufacturing technical field, concretely relates to a vertical digital exposure LDI equipment and exposure system easy to take and put circuit board. BACKGROUND

[0002] The current industry on digital exposure LDI equipment all adopts the mode of single -sided exposure, that is, the circuit board is placed on the working frame of LDI equipment, the board is sucked flat and fixed on the working frame through the mode of vacuumizing and pressing the edge of the circuit board, and the first -sided exposure is completed by scanning exposure. Then, the circuit board is turned over manually or by an automatic plate turning device, and is placed on the working frame of LDI equipment, the board is sucked flat and fixed on the working frame through the mode of vacuumizing and pressing the edge of the circuit board, and the second -sided exposure is completed by scanning exposure. This mode has the following several big pain point problems that cannot be solved:

[0003] The circuit board is placed on the working frame, needs to be sucked flat on the working frame through the mode of vacuumizing the bottom, but some double -sided multilayer boards have many holes, the inside of the hole is protected by ink plugging, and the ink in the hole is sucked out by vacuumizing the bottom, causing plugging oil leakage.

[0004] Based on the problem in the first point, many equipment manufacturers control the vacuum pump or air blower by increasing the frequency converter, reduce the vacuum degree of vacuumizing, and prevent the ink in the hole from being sucked out by the vacuumizing by combining the mode of four -sided pressing plate, but the circuit board cannot be sucked flat on the working frame after the vacuum degree of suction is reduced, and the problem of poor exposure effect is generated.

[0005] The circuit board is placed on the working frame, and the circuit board is in direct contact with the adsorption panel on the working frame, since the ink on the circuit board has not completely dried, the ink is often stuck on the adsorption panel after a period of use, causing copper leakage exposure. In addition, in order to reduce the occurrence of this problem, the adsorption panel needs to be treated with high -level anti -sticking. The cost of this high -level anti -sticking treatment is high, and can only be maintained for two to three months, greatly increasing the hardware cost, even so, the problem of copper leakage exposure cannot be completely solved.

[0006] Fourthly, the circuit board is horizontally placed, and the exposure assembly needs to be placed up and down, the lens on the lower group of exposure assemblies needs to be upward to the circuit board for exposure, the lens on the lens is easy to fall dust and be polluted, leading to poor exposure effect, and the lower group of exposure assemblies is difficult to debug and maintain.

[0007] Fifthly, in order to meet the exposure requirement, the circuit board needs to keep a flat state. If the circuit board is horizontally placed, the circuit board cannot be effectively pulled flat in the horizontal direction due to the action of gravity. UTILITY MODEL CONTENT

[0055] With reference to the drawings and the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0056] In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

[0057] To facilitate the description of the first direction, the second direction and the third direction in the embodiments of the present application, the first direction is the left-right direction in the drawings, the second direction is the front-rear direction in the drawings, and the third direction is the up-down direction in the drawings. Among them, the x-axis arrow direction is the "right" direction in the following text, the y-axis arrow direction is the "up" direction in the following text, and the z-axis arrow direction is the "back" direction in the following text. In the actual application of the present application, it is not limited to this.

[0058] As shown in Figures 1-2 The present embodiment provides a vertical digital exposure LDI device easy to take and place circuit board, which comprises a support seat 110, an exposure assembly 120, and a frame part. The exposure assembly 120 is arranged on the support seat 110 and is used for exposing a workpiece. The frame part comprises a through hole penetrating through a first surface and a second surface of the frame part. The frame part is vertically arranged on the support seat 110, or the frame part is obliquely arranged on the support seat 110. When the workpiece is mounted on the frame part, the workpiece is perpendicular to the support seat 110 or the workpiece is inclined relative to the support seat 110. That is, by vertically or obliquely placing the frame part relative to the support seat 110, and vertically or obliquely placing the first surface and the second surface relative to the support seat 110, the horizontal space occupied by the device 100 can be reduced. By placing the workpiece in the vertically or obliquely arranged frame part, the workpiece is vertically or obliquely arranged, so that the workpiece does not need to be placed horizontally, and the problem that the ink on the workpiece is sucked out when the workpiece is placed horizontally and is subjected to vacuumization to ensure the flatness of the workpiece, resulting in poor exposure effect, can be solved. In addition, the problem that dust is easily deposited on the lower exposure lens when double-sided exposure is performed in a horizontal manner, affecting the exposure effect in the later period, can also be solved. In addition, the vertically or obliquely arranged frame part provided with the through hole can facilitate subsequent taking and placing operations of the workpiece.

[0059] As shown in Figures 1-4As shown, in some embodiments, the frame portion is vertically arranged on the support base 110. However, the present application is not limited thereto, and the frame portion can also be arranged obliquely on the support base 110. The frame portion can be arranged vertically or obliquely on the support base 110, and can also be arranged normally and conveniently.

[0060] The workpiece is installed in the frame portion, and thus the workpiece can also be arranged vertically or obliquely relative to the support base 110. By arranging the workpiece vertically or obliquely, the workpiece does not need to be arranged horizontally, and thus the problem of ink suction does not need to be considered.

[0061] The angle of the frame portion relative to the support base 110 is 30-90 degrees. That is, when the workpiece is installed, the frame portion and the support base 110 can be arranged at an angle of 30-90 degrees.

[0062] The workpiece is installed in the frame portion, and the angle of the frame portion relative to the support base 110 is 30-90 degrees. Thus, when the workpiece is installed in the frame portion, the angle of the workpiece relative to the support base is 30-90 degrees. That is, when the workpiece is installed, the workpiece and the support base 110 can be arranged at an angle of 30-90 degrees, to ensure normal operation of later exposure.

[0063] Exemplarily, the angle of the frame portion relative to the support base 110 can be 30 degrees, or 45 degrees, or 60 degrees, or 75 degrees, or 90 degrees.

[0064] The shape of the through hole includes, but is not limited to, a square shape, a circular shape, and an oval shape. That is, in order to process different workpieces, the through hole can be selected according to requirements, such as a square shape, a circular shape, and an oval shape, to facilitate installation and taking and placing. However, the present application is not limited thereto, and the through hole can also be a parallelogram or an irregular shape, which can be selected according to requirements, and the present application does not limit the shape of the through hole.

[0065] The frame portion is provided with a through hole, so that the workpiece is placed into the frame portion from one side for exposure, and after the exposure is completed, the workpiece is taken out from the other side. At the same time that the workpiece is taken out, the next workpiece is placed into the frame portion from one side, and the workpiece taken out and the workpiece placed in do not interfere with each other, greatly improving the replacement efficiency and thus the exposure efficiency.

[0066] Optionally, the number of through holes on the frame portion is greater than or equal to one, and each through hole can correspond to the installation of at least one workpiece. By arranging not less than one through hole on each frame portion, multiple workpieces can be exposed at the same time. By arranging not less than one workpiece in each through hole, the size of the workpiece can be better considered, and one or more workpieces can be installed in one through hole, to better realize the utilization rate of the frame portion.

[0067] As shown in FIG. 1, the frame portion 100 is provided with a plurality of through holes 101, and each through hole 101 can correspond to the installation of at least one workpiece. Figures 1-3As shown in some embodiments, the device further comprises a driving mechanism, which can drive the frame portion to move in the exposure scanning direction, and / or which can drive the exposure assembly 120 to move in the exposure scanning direction. That is, the frame portion and / or the exposure assembly 120 can be driven to move; the frame portion is moved to the exposure region of the exposure assembly 120 and / or the exposure assembly 120 is moved to the exposure region of the exposure assembly 120 to ensure the normal exposure.

[0068] As shown in some embodiments, the device further comprises a driving mechanism, which can drive the frame portion to move in the exposure scanning direction, and / or which can drive the exposure assembly 120 to move in the exposure scanning direction. That is, the frame portion and / or the exposure assembly 120 can be driven to move; the frame portion is moved to the exposure region of the exposure assembly 120 and / or the exposure assembly 120 is moved to the exposure region of the exposure assembly 120 to ensure the normal exposure.

That is, the frame portion and / or the exposure assembly 120 can be driven to move; the frame portion is moved to the exposure region of the exposure assembly 120 and / or the exposure assembly 120 is moved to the exposure region of the exposure assembly 120 to ensure the normal exposure. Figure 4 As shown in some embodiments, the device further comprises a driving mechanism, which can drive the frame portion to move in the exposure scanning direction, and / or which can drive the exposure assembly 120 to move in the exposure scanning direction. That is, the frame portion and / or the exposure assembly 120 can be driven to move; the frame portion is moved to the exposure region of the exposure assembly 120 and / or the exposure assembly 120 is moved to the exposure region of the exposure assembly 120 to ensure the normal exposure.

[0070] As shown in some embodiments, the device further comprises a driving mechanism, which can drive the frame portion to move in the exposure scanning direction, and / or which can drive the exposure assembly 120 to move in the exposure scanning direction. That is, the frame portion and / or the exposure assembly 120 can be driven to move; the frame portion is moved to the exposure region of the exposure assembly 120 and / or the exposure assembly 120 is moved to the exposure region of the exposure assembly 120 to ensure the normal exposure.

[0071] As shown in some embodiments, the device further comprises a driving mechanism, which can drive the frame portion to move in the exposure scanning direction, and / or which can drive the exposure assembly 120 to move in the exposure scanning direction. That is, the frame portion and / or the exposure assembly 120 can be driven to move; the frame portion is moved to the exposure region of the exposure assembly 120 and / or the exposure assembly 120 is moved to the exposure region of the exposure assembly 120 to ensure the normal exposure. Figures 1-3 As shown in some embodiments, the device further comprises a driving mechanism, which can drive the frame portion to move in the exposure scanning direction, and / or which can drive the exposure assembly 120 to move in the exposure scanning direction. That is, the frame portion and / or the exposure assembly 120 can be driven to move; the frame portion is moved to the exposure region of the exposure assembly 120 and / or the exposure assembly 120 is moved to the exposure region of the exposure assembly 120 to ensure the normal exposure.

[0072] As shown in some embodiments, the device further comprises a driving mechanism, which can drive the frame portion to move in the exposure scanning direction, and / or which can drive the exposure assembly 120 to move in the exposure scanning direction. That is, the frame portion and / or the exposure assembly 120 can be driven to move; the frame portion is moved to the exposure region of the exposure assembly 120 and / or the exposure assembly 120 is moved to the exposure region of the exposure assembly 120 to ensure the normal exposure. Figures 1-4The system comprises two frame sections, namely the first frame section 130 and the second frame section 140. By employing multiple frame sections, while a workpiece is being exposed on one frame section, the other frame sections can handle the loading and unloading of the workpiece; this enables alternating operations without stopping the machine, thereby improving exposure efficiency.

[0073] like Figures 1-3 As shown, taking a frame section including a first frame section 130 and a second frame section 140 as an example, the frame section includes a first frame section 130 and a second frame section 140; the first frame section 130 includes a first mounting part 132, and the second frame section 140 includes a second mounting part 142; the first frame section 130 and the second frame section 140 are disposed on a support base 110, the first mounting part 132 is mounted inside the first frame section 130, and the second mounting part 142 is mounted inside the second frame section 140; the driving mechanism includes a first driving component and a second driving component; the first driving component is used to drive the first frame section 130 to move in the exposure scanning direction; the second driving component is used to drive the second frame section 140 to move in the exposure scanning direction. In other words, by using the first frame section 130 to move in the exposure scanning direction via the first driving component and the second frame section 140 to move in the exposure scanning direction via the second driving component, the exposure operation is performed through the two frame sections, which can save waiting time and speed up the exposure efficiency.

[0074] like Figures 1-3 As shown, in this embodiment, the device 100 further includes a first control unit, which controls the first driving component and the second driving component to drive the first frame portion 130 and the second frame portion 140 to move alternately. That is, when the first driving component drives the first frame portion 130 to move in the exposure scanning direction, the second driving component drives the second frame portion 140 to move away from the exposure scanning direction; similarly, when the first driving component drives the first frame portion 130 to move away from the exposure scanning direction, the second driving component drives the second frame portion 140 to move in the exposure scanning direction. By driving the first frame portion 130 and the second frame portion 140 to move alternately by the first driving component and the second driving component, it can be ensured that one workpiece is exposed and another workpiece is replaced at the same time, reducing the downtime for removing and replacing workpieces after exposure and speeding up the exposure efficiency.

[0075] like Figures 1-3As shown, in this embodiment, the first driving assembly includes a first track 151 and a first driving mechanism; the first track 151 is disposed on the support base 110; the first frame portion 130 is mounted on the first track 151, and the first driving mechanism drives the first frame portion 130 to move along the first track 151; the second driving assembly includes a second track 161 and a second driving mechanism; the second track 161 is disposed on the support base 110; the second frame portion 140 is mounted on the second track 161, and the second driving mechanism drives the second frame portion 140 to move along the second track 161. Using tracks to move the first frame portion 130 and the second frame portion 140 effectively ensures the stability of the displacement of the first frame portion 130 and the second frame portion 140.

[0076] As an example, both the first and second drive mechanisms may include a rack, a gear, and a first motor. The first motor is mounted on the first frame portion 130 and the second frame portion 140, respectively, and the gear is mounted on the first motor. The rack is mounted on the first track 151 and the second track 161, respectively. The rotation of the first motor drives the first frame portion 130 and the second frame portion 140 to move along the tracks via the gear and rack. Using a rack and pinion mechanism to drive the movement of the first frame portion 130 and the second frame portion 140 can effectively ensure the stability of the first frame portion 130 and the second frame portion 140. At the same time, using a rack and pinion mechanism allows the mechanism to stop after moving to an accurate position, ensuring the accuracy of the exposure.

[0077] like Figures 1-3 As shown, in some embodiments, the first track 151 and the second track 161 are located between the first exposure section 121 and the second exposure section 122.

[0078] However, this application is not limited to parallel implementations. For example, the first track 151 and the second track 161 are parallel tracks within the exposure range of the first exposure section 121 and the second exposure section 122, but the distance between the first track 151 and the second track 161, which are not within the exposure range of the first exposure section 121 and the second exposure section 122, gradually increases or gradually decreases.

[0079] Different track settings can be implemented according to the specific circumstances of the equipment, and this application does not impose any restrictions.

[0080] like Figures 1-3 As shown, in this embodiment, the device 100 further includes a third driving mechanism and a fourth driving mechanism; the third driving mechanism is used to drive the first exposure unit 121 to move closer to or away from the first track 151; the fourth driving mechanism is used to drive the second exposure unit 122 to move closer to or away from the second track 161. By using the third driving mechanism to drive the first exposure unit 121 to move and the fourth driving mechanism to drive the second exposure unit 122 to move, the distance between the workpiece and the two exposure units is adjusted, ensuring the accuracy of the exposure.

[0081] likeFigures 1-3 As shown, in this embodiment, the device further includes a second control unit; the second control unit controls the movement of the third drive mechanism and the fourth drive mechanism; when the first frame portion 130 moves into the exposure range of the exposure assembly 120, the second control unit controls the movement of the first exposure portion 121 and / or the second exposure portion 122, so that the workpiece mounted on the first frame portion 130 or the second frame portion 140 is located in the exposure area of ​​the first exposure portion 121 and the second exposure portion 122. By controlling the movement of the first exposure portion 121 and / or the second exposure portion 122 by the second control unit, the workpiece is placed in the area to be exposed, ensuring the accuracy of the exposure.

[0082] like Figures 1-3 As shown, in this embodiment, the first frame portion 130 includes a first frame 131 and a first mounting portion 132; the second frame portion 140 includes a second frame 141 and a second mounting portion 142; the first frame 131 is mounted on the first track 151, and the first mounting portion 132 is located within the first frame 131; the workpiece can be mounted to the first mounting portion 132 via one side or the other side of the first frame 131, and the workpiece can be removed from the first mounting portion 132 via one side or the other side of the first frame 131; the second frame 141 is mounted on the second track 161, and the second mounting portion 142 is located within the second frame 141; the workpiece can be mounted to the second mounting portion 142 via one side or the other side of the second frame 141, and the workpiece can be removed from the second mounting portion 142 via one side or the other side of the second frame 141. The frame structure provides support for the workpiece and prevents exposure deviations; the design of the mounting portion effectively allows for double-sided exposure of the workpiece.

[0083] like Figure 7 As shown, in some embodiments, both the first mounting portion 132 and the second mounting portion 142 of the frame include a fixing member 1a, a clamping member 1b, and a traction mechanism 1c. The fixing member 1a is used to fix one side of the workpiece; the clamping member 1b is used to clamp the other side of the workpiece, and the traction mechanism can drive the clamping member to move away from the fixing member. That is, the workpiece is first fixed by the fixing member 1a and the clamping member 1b, and then the clamping member 1b is moved by the traction mechanism 1c to ensure the flatness of the workpiece and prevent the workpiece from bending due to not being flattened, which would affect the exposure accuracy. At the same time, after clamping from both sides, the traction mechanism 1c tightens the workpiece, and the flatness is no longer maintained by pressing and vacuuming, which can prevent the problem of ink being sucked out due to vacuuming.

[0084] like Figure 6As shown, in some embodiments, the fixing member 1a includes a first pressure plate 1a1, a first permanent magnet, and a first electromagnet 1a3; the first frame 131 and the second frame 141 each include a first pressure plate 1a1 placed on one side thereon, and the first permanent magnet is mounted on the first pressure plate 1a1; the first frame 131 and the second frame 141 are respectively equipped with the first electromagnet 1a3; when a positive current is applied to the first electromagnet 1a3, the first permanent magnet 1a2 and the first electromagnet 1a3 attract each other, which can fix and clamp the workpiece; when a reverse current is applied, the first permanent magnet 1a2 and the first electromagnet 1a3 repel each other, and the workpiece can be removed. The clamping component 1b includes a support plate 1b1, a second pressure plate 1b2, a second permanent magnet, and a second electromagnet 1b4. The support plate 1b1 is mounted on the other side of the first frame 131 and the second frame 141, respectively. The second pressure plate 1b2 is mounted on the support plate 1b1, and the second permanent magnet is mounted on the second pressure plate 1b2. The second electromagnet 1b4 is mounted on the support plate 1b1. When a positive current is applied to the second electromagnet 1b4, the second permanent magnet 1b3 and the second electromagnet 1b4 attract each other, thus clamping and fixing the workpiece. When a reverse current is applied, the second permanent magnet 1b3 and the second electromagnet 1b4 repel each other, and the workpiece can be removed. Through the combined use of the electromagnet and the permanent magnet, the clamping or separation of the workpiece can be achieved quickly.

[0085] like Figure 7 As shown, in an optional embodiment, the traction mechanism 1c includes a second motor 1c11, a rotating shaft 1c12, a conveyor belt 1c13, and a sliding rod 1c14. The second motor 1c11 and the rotating shaft 1c12 are located on the sides of the first frame 131 and the second frame 141 near the clamping member 1b, respectively. The conveyor belt 1c13 and the sliding rod 1c14 are located on both sides of the clamping member 1b, respectively. The two sides of the clamping member 1b are mounted on the sliding rod 1c14. The second motor 1c11 drives the rotating shaft 1c12 to rotate, and the rotating shaft 1c12 drives the conveyor belt 1c13 to rotate. The conveyor belt 1c13 drives the clamping member 1b to move along the sliding rod 1c14, so that the clamping member 1b moves closer to or further away from the fixing member 1a. By using the conveyor belt 1c13 to drive the clamping part to move, the flatness of the workpiece can be ensured, thereby ensuring the exposure accuracy of the workpiece.

[0086] like Figures 1-3As shown, in another embodiment, the traction mechanism 1c includes a third motor 1c21, a tension spring 1c22, a guide rod 1c23, and a pull rope 1c24. The guide rod 1c23 is located on both sides of the clamping member 1b. The two sides of the clamping member 1b are mounted on the guide rod 1c23. The tension spring 1c22 is sleeved on the guide rod 1c23, and the lower end of the tension spring 1c22 is fixed to the clamping member 1b. The tension spring 1c22 provides an upward force to the clamping member 1b, allowing the clamping member 1b to move upward and be stretched and fixed to the lower side of the clamping member 1b. The third motor 1c21 is mounted on the lower side of the frame. The rotation of the third motor 1c21 can drive the stretching and retraction. That is, the motor pulls down the pull rope 1c24, thereby causing the clamping member 1b to move downward, tightening the workpiece fixed on the clamping member 1b, ensuring the flatness of the workpiece, and thus ensuring the exposure accuracy of the workpiece.

[0087] In another embodiment, both the first mounting portion 132 and the second mounting portion 142 of the frame include a fixing member and a tension mechanism 1d; the fixing member 1a is used to fix one side of the workpiece; the tension mechanism 1d is used to connect the other side of the workpiece and stretch the other side of the workpiece away from the fixing member 1a. That is, after one side of the workpiece is fixed by the fixing member, the other side of the workpiece is fixed by the tension mechanism 1d and pulled away from the fixing member, so that the workpiece is flattened and prevented from bending due to not being flattened, which would affect the exposure accuracy; at the same time, by fixing one side and tightening the workpiece on the other side, the flatness is no longer maintained by pressing and vacuuming, which can prevent the problem of ink being sucked out due to vacuuming.

[0088] like Figure 3 As shown, in this embodiment, the device 100 further includes a positioning component 170; when the workpiece moves towards the exposure component 120 along with the first frame portion 130 or the second frame portion 140, the positioning component 170 can position the workpiece; the workpiece is provided with target points. When the workpiece passes the positioning component 170, the positioning component 170 will identify the target points on the workpiece, determine the precise exposure position based on the target points, and then feed back to the exposure component 120, so that the exposure component 120 can accurately expose the workpiece, ensuring the accuracy of the exposure.

[0089] The workpiece is a circuit board, which includes PCB boards, FPC boards, etc.

[0090] The first motor, the second motor 1c11, and the third motor 1c21 are all three-phase asynchronous motors.

[0091] Figure 3The second pick-and-place mechanism 220 removes the workpiece from the second surface of the frame section, while the first pick-and-place mechanism 210 mounts the workpiece from the first surface of the frame section. In other words, by having the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 located on opposite sides of the frame section, a workpiece can be removed from one side while being placed in the other, achieving a tight fit. This saves time compared to separate installation and pick-and-place operations, speeds up replacement efficiency, and ensures constant readiness for exposure.

[0092] However, this application is not limited to this. The first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 can be located on the same side of the frame part and pick up and place workpieces on the same side.

[0093] In some embodiments, the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 are robotic arms, which can be mounted on the support base 110 with the movable end of the robotic arm facing upward.

[0094] ​ The robot arm is mounted on the surface of the support base, but this application is not limited to this. The robot arm can also be set above the support base 110, with the moving end of the robot arm facing downward.

[0095] The robotic arm can be part of a digital exposure LDI device or a robotic arm on a robot that is independent of the digital exposure LDI device; this application does not impose any restrictions.

[0096] In this configuration, if the first pick-and-place mechanism 210 is responsible for retrieving the workpiece and the second pick-and-place mechanism 220 is used for installing the workpiece, then after the first pick-and-place mechanism 210 grips the workpiece, it first moves away from the support base, for example, upwards, so that the workpiece will not collide with the frame when it rotates. Then, it rotates the workpiece from a vertical position to a horizontal position and places the workpiece horizontally in the placement area. After the second pick-and-place mechanism 220 retrieves the workpiece from the first pick-and-place mechanism 210, it can install the next workpiece in the frame and remove it after installation.

[0097] In summary, this utility model provides a vertical digital exposure (LDI) device and exposure system that facilitates the placement and removal of circuit boards. By placing the workpiece in the through-hole on the vertical or inclined frame, and simultaneously making the workpiece vertical or inclined, it is not necessary to lay the workpiece flat. This eliminates the concern that when the workpiece is laid flat, the ink on the workpiece may be sucked out due to vacuum adsorption to ensure its flatness, resulting in poor exposure.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
