Referring to fig. 2 to 4, in an embodiment of the present application, the number of water holes 21 is plural, and the plurality of water holes 21 are distributed in an array, the carrier 20 is used for placing a plurality of FPC products 300, the plurality of FPC products 300 are arranged at intervals along the length direction of the carrier 20, the number of windows 11 is plural, and the plurality of windows 11 are arranged at intervals along the length direction of the carrier 10; when the auxiliary processing jig 100 is in a working state, any window 11 is used for exposing a nickel sheet or a component of one of the FPC products 300. Thus, the auxiliary processing jig 100 can simultaneously clamp a plurality of FPC products 300 and simultaneously clean the plurality of FPC products 300, thereby improving the cleaning efficiency.
Along the length direction of the upper carrier 10, the side of the upper carrier 10 parallel to the length direction is defined as a long side, and the side of the upper carrier 10 parallel to the width direction is defined as a wide side. It will be appreciated that there are two long sides and two wide sides. Accordingly, the long side and the wide side of the downloading tool 20 are defined in the same manner as the uploading tool 10, and will not be described herein.
Specifically, the carrier 20 is FR4 having a thickness of 2mm, a length of 600mm and a width of 250mm. The water holes 21 are milled holes, the diameter of the water holes 21 is 10mm, the distance between any two adjacent water holes 21 is 10mm, that is, the distance between any two adjacent water holes 21 is equal and is 10mm along the length direction and the width direction of the downloading tool 20.
Specifically, the upper carrier 10 is also FR4 having a thickness of 2mm, a length of 600mm and a width of 250mm. The window 11 is a slot, the length of the window 11 is 70mm along the length direction of the upper carrier 10, and the length of the window 11 is 210mm along the width direction of the upper carrier 10, namely, the window 11 is in a strip shape. The distance between the windows 11 at both ends and the edge of the upper carrier 10 along the length direction of the upper carrier 10 is 25mm, that is, the distance between the windows 11 at both ends and the wide edge of the upper carrier 10 is 25mm. Further, the distance between adjacent two windows 11 is 10mm.
It will be appreciated that in other embodiments of the present application, the positions and dimensions of the water passing holes 21 and the windows 11 may be other, and may be adjusted according to practical needs, which is not limited herein.
Referring to fig. 2 to 4, in one embodiment of the present application, a partition rod 12 is disposed between any two adjacent windows 11, a first positioning hole 13 is formed on the partition rod 12, and a second positioning hole 22 and a positioning needle 23 fixedly inserted into the second positioning hole 22 are disposed on the downloading tool 20; when the auxiliary processing jig 100 is in a working state, the second positioning hole 22 is opposite to the first positioning hole 13, and one end of the positioning needle 23, which is far away from the second positioning hole 22, extends into the first positioning hole 13. Thus, when the auxiliary processing tool 100 is in the working state, the positioning pin 23 disposed on the downloading tool 20 can limit the upper tool 10, so as to stop the upper tool 10 from moving substantially along the horizontal direction.
When the auxiliary processing tool 100 is in the working state, one end of the positioning pin 23 away from the second positioning hole 22 extends into the first positioning hole 13, that is, the positioning pin 23 is fixedly mounted on the carrier 20 and protrudes relative to the surface of the carrier 20. In order to enable the upper carrier 10 to rotate relative to the lower carrier 20 through the rotation connecting piece 30, when the upper carrier 10 is parallel to the lower carrier 20, one end of the positioning needle 23 protruding out of the surface of the lower carrier 20 can extend into the corresponding first positioning hole 13, and then the diameter of one end of the positioning needle 23, which is required to be far away from the second positioning hole 22, is smaller than the aperture of the first positioning hole 13, so that the first positioning hole 13 can provide sufficient space, and the positioning needle 23 smoothly enters the first positioning hole 13 in the rotation process of the upper carrier 10, so that interference is avoided.
It will be appreciated that the length of the positioning pin 23 protruding from the surface of the carrier 20 should not be too long, and it is only necessary to ensure that the length of the positioning pin 23 protruding from the surface of the carrier 20 is greater than the thickness of the FPC product 300.
Specifically, the length of the positioning pin 23 protruding from the surface of the carrier 20 is 1.5mm. It will be appreciated that the length of the positioning pin 23 protruding from the surface of the carrier 20 may be other, and may be adjusted according to the thickness of the FPC product, which is not limited herein.
It will be appreciated that the number of first positioning holes 13 on each spacer 12 may be one or more and may be set according to the requirements of use. In the present embodiment, the number of the first positioning holes 13 on each of the partition rods 12 is two, and the distance between the two first positioning holes 13 is 170mm.
Referring to fig. 2 to 5, in an embodiment of the present application, along a height direction of the carrier 20, the carrier 20 includes a bottom surface 201 and a top surface 202 opposite to each other, and the second positioning hole 22 includes a reducing hole 221 and an extending hole 222 connected to each other; the diameter of the variable diameter hole 221 is gradually reduced along the direction from the bottom surface 201 to the top surface 202; the positioning pin 23 has a projection 231 at one end facing the bottom surface 201, and the projection 231 abuts against the wall of the diameter-variable hole 221.
Thus, when the positioning needle 23 is mounted on the carrier 20, the reducing hole 221 can provide guiding function for mounting the positioning needle 23, so as to facilitate the penetration of the positioning needle 23. In addition, the convex part 231 on the positioning needle 23 can be used for fixing the position of the positioning needle 23, and the fixing mode is simple and convenient to install.
Wherein the diameter of the first positioning hole 13 is 2.2mm, and the diameter of the extension hole 222 is 1.95mm. It is understood that the diameters of the first positioning hole 13 and the extension hole 222 may be other values, but are not limited thereto.
In order to prevent the positioning needle 23 from falling out of the first positioning hole 13, a seal may be filled in the diameter-variable hole 221 to seal the same.
Referring to fig. 1, in an embodiment of the application, the auxiliary processing tool 100 further includes a first magnetic attraction member 41 disposed on the upper carrier 10 and a second magnetic attraction member 42 disposed on the lower carrier 20, where the first magnetic attraction member 41 can magnetically attract the second magnetic attraction member 42. The first magnetic attraction piece 41 and the second magnetic attraction piece 42 are magnets, and when the auxiliary processing jig 100 is in a working state, the magnetic poles of the opposite sides of the first magnetic attraction piece 41 and the second magnetic attraction piece 42 are opposite. Thus, the fixed connection of the uploading carrier 10 and the downloading carrier 20 can be realized through the magnetic attraction between the first magnetic attraction piece 41 and the second magnetic attraction piece 42, the connection is quick, and the connection is stable and reliable.
Specifically, when the auxiliary processing jig 100 is in a working state, the N pole of the first magnetic attraction piece 41 is located above the S pole of the second magnetic attraction piece 42, and the N pole of the first magnetic attraction piece 41 and the N pole of the second magnetic attraction piece 42 are opposite and attract each other, so that the uploading tool 10 and the downloading tool 20 are stably connected under the attraction force between the first magnetic attraction piece 41 and the second magnetic attraction piece 42. It will be appreciated that the N pole of the first magnetic attraction member 41 may be located below the S pole thereof, and correspondingly, the N pole of the second magnetic attraction member 42 may be located below the S pole thereof, as well as maintain the attractive force therebetween.
Furthermore, in other embodiments of the present application, one of the first magnetic attraction member 41 and the second magnetic attraction member 42 is a magnet, and the other is a magnetic metal member.
Specifically, the magnetic metal member is a metal member that can attract the magnet and includes metals such as iron, nickel, cobalt, etc., and it is understood that the magnetic attraction between the magnet and the magnetic metal member can also achieve stable connection between the upper carrier 10 and the lower carrier 20, which is not limited herein.
Referring to fig. 1, in an embodiment of the present application, the number of the first magnetic attraction pieces 41 and the second magnetic attraction pieces 42 is plural, the first magnetic attraction pieces 41 are distributed at intervals on the peripheral side of the upper carrier 10, and the second magnetic attraction pieces 42 are distributed at intervals on the peripheral side of the lower carrier 20; when the auxiliary processing jig 100 is in the working state, the second magnetic attraction piece 42 is disposed opposite to the first magnetic attraction piece 41.
On the one hand, by increasing the number of the first magnetic attraction pieces 41 and the second magnetic attraction pieces 42, the attractive force between the upper carrier 10 and the lower carrier 20 can be increased; on the other hand, the plurality of first magnetic attraction pieces 41 are distributed at intervals on the peripheral side of the upper carrier 10, and the plurality of second magnetic attraction pieces 42 are distributed at intervals on the peripheral side of the lower carrier 20, so that the distribution of the first magnetic attraction pieces 41 on the upper carrier 10 and the distribution of the second magnetic attraction pieces 42 on the lower carrier 20 are relatively uniform, and the distribution of attraction force between the upper carrier 10 and the lower carrier 20 is relatively uniform, thereby improving the connection stability of the upper carrier 10 and the lower carrier 20.
The first hinge 31 is mounted on one of the wide sides of the upper carrier 10, and the wide sides and two long sides of the first hinge 31 are not mounted with a plurality of first magnetic attraction pieces 41 uniformly distributed.
It can be appreciated that, when the auxiliary processing tool 100 is in the working state, the second magnetic attraction pieces 42 are disposed opposite to the first magnetic attraction pieces 41, so that the distribution condition of the second magnetic attraction pieces 42 on the downloading tool 20 is the same as the distribution condition of the first magnetic attraction pieces on the uploading tool 10, and reference can be made to the distribution of the first magnetic attraction pieces on the uploading tool 10, which is not repeated herein.
