Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB (printed circuit board) manufacturing equipment technology, and in particular to a non-contact tooling for a horizontal PCB production line, used to stably support the PCB during transmission and avoid surface scratches or contamination. Background Technology
[0002] PCBs (printed circuit boards) need to be transferred through multiple processes in horizontal production lines (such as electroplating, etching, and cleaning). Traditional horizontal lines mainly use mechanical clamping, rollers, or belts for contact support and transfer, which can easily lead to the following problems:
[0003] 1) Scratches on the PCB (printed circuit board) surface (especially for flexible boards and thick boards);
[0004] 2) Contamination or residual medication at the contact site;
[0005] 3) Poor support for thin plates. Utility Model Content
[0006] The purpose of this utility model is to solve the problems of the prior art and provide a non-contact tooling for a horizontal PCB production line, which has the advantages of no direct contact between the PCB and the horizontal line, and solves the problems of surface scratches and chemical contamination caused by flexible boards and thick boards passing through the horizontal line.
[0007] The purpose of this utility model is achieved through the following technical solution: a non-contact fixture for a horizontal PCB production line, comprising a fixture body; a board placement groove is provided on the fixture body; the board placement groove is a hollow groove; support protrusions are provided below the side walls of the board placement groove; the support protrusions contact the ineffective areas on both sides of the PCB to support the PCB; when the fixture is in use, the PCB of the corresponding specification is fixedly placed in the board placement groove and supported and fixed by the support protrusions; the support protrusions help to effectively protect the lower surface of the PCB, so as to effectively avoid the risk of scratches and abrasions on the lower surface when the board passes through the horizontal line; the board placement groove is hollowed out to prevent the corresponding PC chemicals from being unable to drain effectively and causing contamination on the PCB surface; the width of the support protrusions can be selected according to the ineffective area of the board edge of the corresponding specification of the PCB, so as to ensure that the board surface is not contaminated by chemicals and that the lower surface of the board can be in contact with the horizontal line.
[0008] The board placement slot is also provided with hand grip slots on both sides; the hand grip slots are used to hook the PCB; the hand grip slots make it easier to place and pick up the corresponding PCB. When placing and picking up the board, the effective area inside the board may be touched, causing contamination of the board surface. Therefore, the hand grip slots can be used to pick up the ineffective area of the board edge that is in contact with the PCB with both hands, thereby eliminating the contamination of the effective area of the board caused by the operator placing and picking up the PCB.
[0009] The thickness of the fixture body is greater than the thickness of the PCB. After the PCB is placed in the board placement slot, the surface of the PCB is not higher than the surface of the fixture body. The thickness of the fixture body is greater than the thickness of the PCB of the corresponding specification. The board placement slot can completely protect the corresponding PCB, so that when the BCP board passes through the horizontal line, the risk of the upper surface being scratched or abraded can be effectively avoided.
[0010] The length and width of the board placement slot are both greater than the length and width of the PCB; the difference between the length of the board placement slot and the length of the PCB is less than 1mm; the difference between the width of the board placement slot and the width of the PCB is less than 1mm; the difference between the length and width of the board placement slot and the length and width of the PCB is less than 1mm, to prevent PCB displacement. Since the bottom of the board placement slot is hollow, it can ensure uniform flow of the chemical solution and prevent chemical residue.
[0011] The support protrusion is a stepped support platform; compared with protrusions, columns, and other structures, the stepped support platform is more conducive to the stable support of the PCB and reduces displacement.
[0012] A further technical solution is that the width of the stepped support platform is smaller than the width of the ineffective area of the PCB edge. The width of the stepped support platform is set according to the width of the ineffective area of the PCB edge, which can prevent the effective area of the PCB surface from directly contacting the chemical solution and causing defects such as contamination.
[0013] This utility model has the following advantages:
[0014] 1. The non-contact tooling of the PCB horizontal production line of this utility model has a board placement groove that can completely protect the PCB of the corresponding specifications, so as to effectively avoid the risk of scratches and abrasions on the upper surface when the board passes through the horizontal line.
[0015] 2. The non-contact tooling of this PCB horizontal production line can effectively support the corresponding PCB and protect the lower surface of the PCB through the support protrusions, so as to effectively avoid the risk of the lower surface being scratched or abraded when the board passes through the horizontal line.
[0016] 3. The non-contact tooling of this PCB horizontal production line has a hollowed-out board placement groove. The purpose is to prevent the chemical from being unable to be effectively discharged from the corresponding PCB, which would cause contamination on the PCB surface. The width of the corresponding support protrusion can be selected according to the ineffective area of the corresponding PCB edge, which can ensure that the board surface is not contaminated by the chemical and that the lower surface of the board can be in no contact with the horizontal line.

[0028] The board placement slot 2 is also provided with hand grip slots 4 on both sides; the hand grip slots 4 are used to hook the PCB; the hand grip slots 4 can make it easier to place and pick up the corresponding PCB. When placing and picking up the board, it may come into contact with the effective area inside the board, causing contamination of the board surface. Therefore, the hand grip slots 4 can be used to pick up the ineffective area of the board edge that comes into contact with the PCB with both hands, thereby eliminating the contamination of the effective area of the board caused by the operator placing and picking up the PCB.
[0029] The thickness of the fixture body 1 is greater than the thickness of the PCB. After the PCB is placed in the board placement slot 2, the surface of the PCB is not higher than the surface of the fixture body 1. The thickness of the fixture body 1 is greater than the thickness of the PCB of the corresponding specification. The board placement slot 2 can completely protect the corresponding PCB, so that when the BCP board passes through the horizontal line, the risk of the upper surface being scratched or abraded can be effectively avoided.
[0030] The length and width of the board placement groove 2 are both greater than the length and width of the PCB; the difference between the length of the board placement groove 2 and the length of the PCB is less than 1mm; the difference between the width of the board placement groove 2 and the width of the PCB is less than 1mm; the difference between the length and width of the board placement groove 2 and the length and width of the PCB is less than 1mm, which prevents the PCB from shifting. Since the bottom of the board placement groove 2 is hollow, it can ensure uniform flow of the chemical solution and prevent chemical residue.
[0031] The support protrusion 3 is a stepped support platform; compared with protrusions, columns and other structures, the stepped support platform is more conducive to the stable support of the PCB and reduces displacement.
[0032] A further technical solution is that the width of the stepped support platform is smaller than the width of the ineffective area of the PCB edge.
