The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0071] In order to further explain the technical means and effects adopted by the present application to achieve the intended purpose, the present application is described in detail below in conjunction with the accompanying drawings and implementation methods.

[0072] See also Figure 1 and Figure 2 , an embodiment of the present application provides a fixing fixture 100 for stripping, which is used to fix a workpiece 200 to be stripped. In this embodiment, the workpiece 200 includes a main body 210 and limit blocks 220 extending from both ends of the main body 210, and the two limit blocks 220 are located on two opposite sides of the main body 210. There is a height difference between the main body 210 and the limit blocks 220. The surface of the main body 210 has a film to be stripped (not shown). In this embodiment, the workpiece 200 can be a workpiece or a test block that needs to be stripped.

[0073] The fixed fixture 100 includes a support frame 10, a mounting member 20, a conductive member 30, and a locking assembly 40. The support frame 10 includes a support column 11 and two brackets 12 disposed at both ends of the support column 11, and the support column 11 extends along a first direction X. The two brackets 12 are respectively disposed at both ends of the support column 11 in the first direction X. In some embodiments, the support column 11 is a hollow structure, and the hollow support column 11 can be passed through a string rod of a stripping rack (not shown), and multiple fixed fixtures 100 can be installed on the stripping rack through their support columns 11.

[0074] The mounting member 20 is disposed on the bracket 12 and is used to fix a plurality of processing members 200. The mounting member 20 includes a bottom plate 21, which can be fixed to the bracket 12 by welding, threaded connection, etc. The bottom plate 21 has a first surface 211 and a second surface 212 that are arranged opposite to each other. The first surface 211 is arranged away from the bracket 12, and the second surface 212 is arranged toward the bracket 12. The processing members 200 are used to be mounted on the first surface 211, and the film to be stripped is located on the surface of the main body 210 away from the first surface 211. A plurality of openings 213 are provided on the bottom plate 21 to expose the plurality of processing members 200, and each opening 213 passes through the first surface 211 and the second surface 212.

[0075] The conductive member 30 is disposed on the second surface 212. The locking assembly 40 is disposed on the mounting member 20. The locking assembly 40 includes a base 41, a movable member 42, and a fastening member 43 fixed to and connected to the movable member 42. The base 41 is mounted on the bottom plate 21, and the movable member 42 is movably mounted on the base 41. The movable member 42 is used to move toward the bottom plate 21 under the action of an external force, thereby driving the fastening member 43 to abut against the conductive member 30, so that the conductive member 30 passes through the opening 213 and is close to the workpiece 200, so that the conductive member 30 is electrically connected to a plurality of workpieces 200. The movable member 42 is also used to move away from the bottom plate 21 under the action of an external force, thereby driving the fastening member 43 to disengage from the conductive member 30, so that the conductive member 30 and the workpiece 200 are separated, so that the workpiece 200 can be taken and placed from the bottom plate 21. In the above scheme, the locking assembly 40 is supported against the conductive part 30 to realize the electrical connection between the conductive part 30 and the multiple processed parts 200. At the same time, the setting of the locking assembly 40 also realizes the fixation of the conductive part 30. The structure is simple and easy to disassemble. The stripping of multiple processed parts 200 can be realized at the same time, thereby improving the stripping efficiency.

[0076] See also Figure 2 and Figure 3In some embodiments, the mounting member 20 further includes a limiting plate 22 disposed on opposite sides of the bottom plate 21, and the limiting plate 22 is convexly disposed on the first surface 211 of the bottom plate 21. The limiting plate 22 is used to limit the workpiece 200 on the bottom plate 21. A baffle 23 is further disposed on one side of the bottom plate 21 in the first direction X, and the baffle 23 is connected to the two limiting plates 22 and disposed on the first surface 211 of the bottom plate 21. The limiting plate 22 includes a first plate 221 and a second plate 222. The first plate 221 is connected between the bottom plate 21 and the second plate 222, and the second plate 222 is parallel to the bottom plate 21. Thus, a limiting space 223 is formed between the bottom plate 21, the first plate 221, the second plate 222 and the baffle 23. The two limiting blocks 220 of the workpiece 200 are respectively accommodated in the two limiting spaces 223, thereby achieving the fixation of the workpiece 200. In this embodiment, the plurality of workpieces 200 can be fixed to the mounting member 20 along the first direction X, thereby achieving the installation and fixation of the plurality of workpieces 200. When the mounting member 20 is placed along the first direction X, the baffle 23 is also used to support the plurality of workpieces 200. The structures of the limiting plate 22 and the baffle 23 can be adjusted according to the shape of the workpiece 200 to be processed.

[0077] See also Figure 2 and Figure 3 In some embodiments, the conductive member 30 includes a main board 31 and a plurality of conductive sheets 32 disposed on the main board 31. When the abutting member 43 abuts against the main board 31, the conductive sheet 32 ​​abuts against the workpiece 200 through the opening 213, thereby achieving electrical connection between the workpiece 200 and the conductive sheet 32, and also facilitating simultaneous installation and fixation of a plurality of workpieces 200. The conductive member 30 is detachably fixed to the bottom plate 21 through the locking assembly 40, which facilitates replacement of the conductive member 30 with a new one after the conductive member 30 has been used for a period of time.

[0078] In other embodiments, a conductive column (not shown) is provided on the surface of the main board 31 facing the base plate 21. When the fastening member 43 is pressed against the main board 31, the conductive column passes through the opening 213 and presses against the workpiece 200, thereby realizing electrical connection between the main board 31 and the workpiece 200.

[0079] See also Figure 2 and Figure 3In some embodiments, a plurality of conductive sheets 32 are arranged in pairs, and each pair of conductive sheets 32 includes a first conductive sheet 321 and a second conductive sheet 322, and the first conductive sheet 321 and the second conductive sheet 322 are respectively arranged on opposite sides of the main board 31. Each workpiece 200 is electrically connected to at least one pair of conductive sheets 32 (i.e., a first conductive sheet 321 and a second conductive sheet 322). Along the first direction X, the first conductive sheet 321 and the second conductive sheet 322 of each pair of conductive sheets 32 correspond to each other at the same height of the main board 31, and abut against the same workpiece 200, so as to ensure that the conductive sheet 30 and the workpiece 200 are electrically connected.

[0080] See also Figure 3 and Figure 4 In some embodiments, the conductive sheet 32 ​​is an arc-shaped sheet. The conductive sheet 32 ​​extends from the side of the main board 31 and protrudes toward the bottom plate 21 compared to the main board 31. Therefore, when the movable member 42 is pressed against the main board 31, the arc-shaped conductive sheet 32 ​​and the processing member 200 can fully contact each other.

[0081] See also Figure 4 and Figure 5 In some embodiments, the base 41 has a fixed plate 411 and a plurality of side plates 412 disposed on the same surface of the fixed plate 411, and the base 41 is mounted on the bottom plate 21 through the fixed plate 411. The plurality of side plates 412 and the fixed plate 411 enclose a cavity 413. The movable member 42 is at least partially disposed in the cavity 413 and can move in the cavity 413. In this embodiment, three side plates 412 are disposed on the same surface of the fixed plate 411, and the cavity 413 has an opening 414, through which the abutting member 43 passes to connect with the movable member 42. The general outline of the base 41 may be square.

[0082] Combination Figure 6 The locking assembly 40 further includes a first elastic member 421, which is accommodated in the cavity 413 and abuts between the movable member 42 and the fixed plate 411. The movable member 42 moves toward the fixed plate 411 under the action of an external force, thereby driving the abutting member 43 to move toward the mounting member 20 and abut against the main board 31. When the movable member 42 moves, the first elastic member 421 is compressed.

[0083] The movable member 42 may have a receiving groove 4224 on one side facing the first elastic member 421 , and one end of the first elastic member 421 is received in the receiving groove 4224 , thereby preventing the first elastic member 421 from being offset during the movement of the movable member 42 , thereby preventing the first elastic member 421 from being separated from the movable member 42 .

[0084] See also Figure 5 and Figure 6In some embodiments, the locking assembly 40 also includes a pressing member 44 and a rotating shaft 45. The pressing member 44 includes two pressing plates 441, one end of the two pressing plates 441 is connected, and the connection of the two pressing plates 441 forms a clamping portion 442, and the other ends of the two pressing plates 441 are rotatably connected to the base 41 through the rotating shaft 45. The two pressing plates 441 rotate relative to the base 41 through the rotating shaft 45. When the two pressing plates 441 rotate until the clamping portion 442 abuts against the movable member 42, the clamping portion 442 applies a force to the movable member 42 to move toward the bottom plate 21, so that the movable member 42 compresses the first elastic member 421 and drives the clamping member 43 to move toward the main board 31. The two pressing plates 441 abut against the movable member 42 to drive the clamping member 43 to move, and the structure is simple and easy to operate. When the two pressing plates 441 rotate until the clamping portion 442 disengages from the movable member 42, as shown Figure 2 The first elastic member 421 pushes the movable member 42 to move away from the bottom plate 21, and drives the clamping member 43 to move away from the main board 31. The clamping member 43 is separated from the main board 31, and the conductive sheet 32 ​​is separated from the processed member 200. The main board 31 can be removed from the bottom plate 21, and the processed member 200 can be removed from the mounting member 20.

[0085] In some embodiments, the end of the movable member 42 away from the first elastic member 421 is an arc surface, and the arc surface is convex in the direction away from the first elastic member 421. The pressing portion 442 is pressed against the arc surface of the movable member 42. The setting of the arc surface provides a guiding effect for the pressing sheet 441 to rotate relative to the rotating shaft 45. Specifically, the movable member 42 is a block structure.

[0086] See also Figure 5 and Figure 6 , a slot 4221 is provided on the movable part 42, and the slot 4221 has a first end 4222 and a second end 4223 relative to each other in the moving direction of the movable part 42. The moving direction of the movable part 42 is perpendicular to the first direction X. The rotating shaft 45 passes through the slot 4221 and is rotatably connected to the base 41, and the rotating shaft 45 is placed between the first end 4222 and the second end 4223. The slot 4221 is arranged to provide an escape space for the movable part 42 compared to the movement of the rotating shaft 45. Specifically, the slot 4221 is a waist-shaped slot. When the clamping portion 442 and the movable part 42 are separated, the rotating shaft 45 limits the movable part 42 through the second end 4223 to prevent the movable part 42 from being separated from the base 41, resulting in the separation of the movable part 42 and the pressing member 43 from the base 41.

[0087] See also Figure 5 and Figure 6In some embodiments, the abutting member 43 includes a connecting plate 431, a fixed shaft 432 and a abutting block 433. One end of the connecting plate 431 is fixedly connected to the movable member 42, and the other end of the connecting plate 431 is movably connected to the fixed shaft 432. The movable member 42 and the fixed shaft 432 are located on the same side of the connecting plate 431. The abutting block 433 is fixed to one end of the fixed shaft 432, and the abutting block 433 is used to abut against the conductive member 30. One end of the connecting plate 431 can be fixed to the movable member 42 by welding, threaded connection or clamping. The connecting plate 431 is vertically connected to the movable member 42, and the relatively inclined connection mode, when the movable member 42 moves in the solution provided in this embodiment, the fixed shaft 432 and the abutting block 433 are driven to move by the connecting plate 431, and the force of the pressing part 442 on the movable member 42 is transmitted to the fixed shaft 432 through the connecting plate 431, which can increase the force of the abutting block 433 against the main board 31. In some embodiments, the pressing block 433 may be made of rubber material. The pressing block 433 may have a general outline of a cylinder.

[0088] See also Figure 5 and Figure 6 In some embodiments, the abutting member 43 further includes a second elastic member 434. One end of the connecting plate 431 away from the movable member 42 is sleeved on the fixed shaft 432 through a hole, and the end of the connecting plate 431 can move along the axial direction of the fixed shaft 432. The second elastic member 434 is sleeved on the fixed shaft 432, and both ends of the second elastic member 434 are abutted on the connecting plate 431 and the abutting block 433. When the movable member 42 moves toward the bottom plate 21, the movable member 42 drives the connecting plate 431 to move, and the connecting plate 431 compresses the second elastic member 434, so that the abutting block 433 applies a pushing force to the main board 31, and the main board 31 moves toward the bottom plate 21 relative to the conductive sheet 32, so that the conductive sheet 32 ​​is closely attached to the workpiece 200 through the opening 213, so as to realize the electrical connection between the conductive member 30 and the workpiece 200. A protrusion 435 is provided on the outer periphery of the end of the fixed shaft 432 away from the clamping block 433, and the second elastic member 434 is supported between the clamping block 433 and the protrusion 435. The setting of the protrusion 435 is to limit the connecting plate 431 on the fixed shaft 432 to prevent the connecting plate 431 from falling off from the end of the fixed shaft 432.

[0089] In this embodiment, the first elastic member 421 and the second elastic member 434 may both be springs, or other components such as tension springs or torsion springs.

The deplating tank contains a deplating liquid, and the fixed fixture 100 and the cathode plate are both immersed in the deplating liquid. The fixed fixture 100 is used to assemble a plurality of workpieces 200 to be deplated. Start the power supply to achieve deplating of the workpiece 200.

[0092] In the present application, the locking assembly 40 is pressed against the conductive part 30 to fix the conductive part 30, and at the same time realizes the electrical connection between the conductive part 30 and the workpiece 200; and the movable part 42 in the locking assembly 40 can also drive the pressing part 43 to separate from the conductive part 30 under the action of external force, so that the conductive part 30 and the workpiece 200 are separated, so that the workpiece 200 can be taken and placed from the mounting part 20.
