In some embodiments, the diameter of the end portion 115a of the electrode probe 115 is not greater than 5 mm, such as 5 mm or 2.3 mm. Such a diameter allows the end 115a of the electrode probe 115 to protrude into the transverse groove w10 of the workpiece w (eg, having a 6 mm hole diameter). In some embodiments, the difference between the diameter value of the end portion 115a and the diameter value of the lateral groove w10 is not greater than 1 mm, so as to ensure the effect of electrochemical machining.

FIG. 2 shows a schematic top view of a lower jig 210 of an electrochemical system according to some embodiments of the present disclosure. For simplicity and clarity of illustration, some details/subcomponents of the exemplary system are not explicitly labeled/shown in this figure.

The jig lower mold 210 includes a bearing base 211 and two first (cathode) electrode units 212, and each first electrode unit 212 includes four electrode modules 213a, 213b, 213c, and 213d.

Each of the electrode modules (eg, the electrode module 213b) includes a driving mechanism 216 disposed on the bearing surface 211a of the bearing base 211, and is driven by the driving mechanism 216 to reciprocate in a traveling direction (eg, the x-direction shown in the figure). The probe base 214 and the electrode probe 215 mounted on the probe base 214 . In some embodiments, the driving mechanism 216 includes a base (not shown in the figure) fixed on the bearing surface, a guide rod (not shown in the figure) extending from the base 116a toward the orientation structure 211c, A pneumatic cylinder 216c installed on the base, and a connecting piece 216d connected between the probe base 214 and the pneumatic cylinder 216c. When the connecting member 216d is driven by the pneumatic cylinder 216c, the probe holder 214 is driven to reciprocate in its traveling direction (eg, the x-direction shown in the figure).

In some embodiments, the probe holder 214 is driven by the drive mechanism 216 to move between an inserted position and a remote position (eg, the current position shown in FIG. 1 ). When the probe holder 214 is in the insertion position, the electrode probe 215 extends into the transverse groove of the workpiece w (eg, as shown by the dotted line extending along the x-direction in the figure).

The traveling directions of the probe bases 214 of two adjacent electrode modules 213a, 213b, 213c, and 213d (eg, the electrode modules 213a, 213b) are substantially orthogonal in plan view. In this way, after fixing the workpiece w, the ends of the probes can be moved toward the two substantially orthogonal side surfaces of the workpiece w, respectively. In some cases, the workpiece w has a plurality of transverse flow channels that are generally orthogonal (as shown by the dashed lines extending in the x, y directions in the figure), and the partially orthogonal transverse flow channels are in fluid communication with each other. In some embodiments, the plurality of transverse flow channels of the workpiece w are in fluid communication with the longitudinal flow channels. In the illustrated embodiment, the probe holder 214 of the electrode module 213a (213b) is driven by the driving mechanism 216 to move in the x-direction (y-direction), and the included angle between the x-direction and the y-direction is 90 degrees, Instead, the probe 215 can be protruded into a plurality of transverse flow channels that are substantially orthogonal to the workpiece w.

In other embodiments, the ends (the portions of the electrode probes that are assembled to protrude into the lateral grooves of the workpiece w) may be designed to be relatively narrower (or relatively wider) than other sections of the electrode probes . In some embodiments, the diameter of the end of the electrode probe 213 is not greater than 5 mm, such as 5 mm or 2.3 mm.

Figure 3 shows a flowchart of a method of processing some exemplary electrochemical systems in accordance with the present disclosure. The embodiment of the processing method of the electrochemical system includes the procedures S301 to S312, which are specifically described as follows.

Procedure S301: Receive a workpiece on the bearing surface of the bearing seat, the workpiece having grooves (eg, longitudinal and transverse grooves w10, w20). For example, in the embodiment shown in FIG. 1 , the workpiece w is placed on the orientation structure 111 c above the bearing surface 111 a of the bearing seat 111 . In other embodiments, the carrier can be designed to receive the workpiece in contact with its carrier surface.

Procedure S302 : Operate the anode electrode unit (eg, the second electrode unit 122 ) disposed above the bearing seat, and drive the anode electrode unit and the bearing seat to move relatively to contact the workpiece. The anode electrode unit includes a conductive member (eg, the conductive member 123 ) and a pad (eg, the pad 124 ) arranged to move simultaneously with the conductive member, and the pad is formed with a flow channel structure (eg, a flow channel structure) 124a), the flow channel structure has a liquid outlet (eg, a liquid outlet 124b) facing the bearing surface. in some operations In this situation, the user can operate the control panel, so that the lifting system (eg, the lifting system 150 ) moves the upper jig (eg, the upper jig 120 ) downward, so that the gas supply system (not shown in the figure) provides a certain air pressure. Gas is supplied to the pneumatic cylinder (eg, the pneumatic cylinder 116c ) of the cathode electrode module, so that the conductive member (eg, the conductive member 123 ) of the anode electrode unit (eg, the second electrode unit 122 ) contacts the workpiece.

Procedure S303: Operate a plurality of cathode electrode modules (eg, the electrode modules 113 ) disposed on the carrying surface, the cathode electrode modules having electrode probes (eg, the probe base 114 ) disposed on the probe base For example, the electrode probe 115), the probe bases (such as the probe base 214) of the adjacent two (such as the electrode modules 213a, 213b) of the plurality of cathode electrode modules are driven in a substantially orthogonal traveling direction ( For example, the workpiece is approached in the x-direction and y-direction shown in FIG. 2 , so that the electrode probe (eg, the electrode probe 215 ) protrudes into the groove of the workpiece. In some operating situations, the user can operate the control panel to make the gas supply system provide gas with a certain pressure to the pneumatic cylinder (eg, the pneumatic cylinder 116c ) of the cathode electrode module, so that the pneumatic cylinder pushes the probe holder (eg, the probe holder) 114) Move to the insertion position so that the electrode probe (eg, electrode probe 115) extends into the groove of the workpiece.

In some operating conditions, the probe holders 214 of adjacent two (eg, electrode modules 213a, 213b) of the four electrode modules (eg, electrode modules 213a, 213b, 213c, 213d) are not simultaneously driven to insert position, so as to prevent the electrode probes 215 from being damaged by touching each other. For example, the user can operate the control panel to move the probe holders (eg, the probe holder 214 ) of the two opposite electrode modules (eg, 213a, 213c ) to the insertion position synchronously, and make the two electrode modules ( For example, after 213a, 213c) are moved back to the remote position, the probe holder of another pair of electrode modules (for example, 213b, 213d) is moved to the insertion position synchronously.

Procedure S304: Apply a first voltage between the cathode electrode module (eg, the electrode module 113 ) and the anode electrode unit (eg, the second electrode unit 122 ). In some operating scenarios, a user may operate a control panel to cause a current supply system (eg, current supply system 140 ) to provide DC power to the cathode electrode module and the anode electrode unit.

In some embodiments, the sequence of procedure S302, procedure S303, and procedure S304 may be interchanged.

Procedure S305: Detect the contact between the electrode probe and the workpiece by the probe contact sensor (eg, the probe contact sensor 160) signally connected to the cathode electrode probe (eg, the electrode probe 115). No, and generate the corresponding sensing signal. In some embodiments, the control system causes the control panel to generate an output indicating whether the workpiece is in contact with a cathode electrode probe (eg, electrode probe 115 ) based on the sensed signal; the output may be a visual or Audible output that can be identified by the user.

When the sensing signal indicates that the cathode electrode probe is not in contact with the workpiece, the process proceeds to step S306 : operate a fluid supply device (eg, the fluid supply device 130 ) to provide an electrochemical fluid (eg, sodium nitrate) to the workpiece. grooves, so that the electrolyte not only contacts the workpiece, but also contacts the end of the electrode probe through the lateral grooves of the workpiece.

Procedure S307: Apply a second voltage between the cathode electrode module, the electrolyte, and the anode electrode unit to perform deburring processing on the workpiece.

Procedure S308: Operate the plurality of cathode electrode modules to move their probe bases to a distant position. In some operating situations, the user can operate the control panel to make the gas supply system provide gas with a certain pressure to the pneumatic cylinder (eg, the pneumatic cylinder 116c ) of the cathode electrode module, so that the pneumatic cylinder pushes the probe holder (eg, the probe holder) 114) Move the electrode probe (eg, electrode probe 115) to a remote position away from the groove of the workpiece.

Procedure S309: Operate the aforementioned anode electrode unit to keep it away from the workpiece. In this way, the workpiece can be allowed to be moved away from the carrier by manual or automatic (eg robotic arms), so that another workpiece to be processed can be placed on the carrier. In some embodiments, the order of procedure S308 and procedure S309 may be interchanged.

In some operating situations, when the user recognizes that the cathode electrode probe is not in contact with the workpiece according to the output, the user can operate the control panel to execute the procedures S306 - S309 . In some embodiments Among them, the control system may be designed to automatically execute at least one of S306 to S309 when the probe contact sensor determines that the cathode electrode probe is not in contact with the workpiece.

When the sensing signal indicates that the cathode electrode probe is in contact with the workpiece, the process proceeds to a procedure S310: the cathode electrode probe is driven to move out of the groove of the workpiece. In some cases, the contact of the cathode electrode probe with the workpiece indicates that the structure of the workpiece is out of specification, and machining of it is not necessary. Therefore, by executing the program S305 and stopping the machining of the cathode electrode probe when it is in contact with the workpiece, the effect of screening out the workpiece that meets the specification can be additionally obtained, and the machining cost can be saved.

Procedure S311: Operate the anode electrode unit to keep it away from the workpiece.

In some operating situations, the user may execute the procedures S310 - S311 by operating the control system. In some embodiments, the control system may be designed to automatically execute at least one of the procedures S310 to S311 when the probe contact sensor determines that the cathode electrode probe is in contact with the workpiece.
