Abstract
Description
Technical Field
[0001] The present application belongs to the field of PCB technology, and in particular relates to an auxiliary carrier for PCB horizontal production line. Background Art
[0002] With the continuous advancement of science and technology, PCB (Printed circuit board) is gradually developing towards smaller size and thinner boards. In the past, the horizontal line design had a large roller spacing. When some PCBs were formed (gong boards) and the smaller thin boards passed through the finished product cleaning line or the surface treatment horizontal line (OSP, tinning, etc.), the boards were prone to falling off the cylinder or getting stuck, causing line stoppage or quality problems such as scratches. For this reason, the relevant technology provides the following "board-with-board" method to meet the production of small-size thin boards with super process capacity: a thin board is placed behind a thicker PCB (usually the board thickness is required to be greater than 1.0mm), and the two PCBs are connected with tape to achieve the process capacity of horizontal line production.
[0003] However, this production method requires both adhesive application and post-production adhesive removal, which is very labor-intensive, time-consuming and material-intensive, and is not suitable for mass production. There is also a risk of residual adhesive, and the tape can easily cause oil loss on the board surface. Utility Model Content
[0004] The present application provides an auxiliary carrier for a PCB horizontal production line, which is used to solve the problem that the existing surface treatment horizontal line or finished product cleaning line exceeds the process capacity of the existing equipment when producing thin plates (for example, plate thickness ≤ 0.4mm) or smaller PCBs, so as to avoid the problem of falling off the cylinder or getting stuck.
[0005] In order to achieve the above application purpose, the technical solution adopted in this application is as follows:
[0006] The embodiment of the present application provides an auxiliary carrier for PCBs passing through a horizontal production line, including a carrier board, the carrier board is provided with a plurality of board placement cells, the board placement cells include a card slot opened through the carrier board, the side wall of the card slot is provided with a step structure for carrying the PCB, and the card slot is also provided with a baffle strip for preventing the PCB from falling;
[0007] The difference between the thickness of the carrier board and the thickness of the step structure is greater than the thickness of the PCB.
[0008] In some embodiments, the thickness of the PCB is less than or equal to 0.4 mm.
[0009] In some embodiments, the thickness of the step structure is 1 mm.
[0010] In some embodiments, D≥a+b+0.6 mm, D is the thickness of the carrier board, a is the thickness of the PCB, and b is the thickness of the step structure.
[0011] In some embodiments, the length of the board unit cell is equal to the length of the PCB plus 2 mm, and the width of the board unit cell is equal to the width of the PCB plus 2 mm.
[0012] In some embodiments, the spacing between adjacent plate cells is 8 mm.
[0013] In some embodiments, the baffle strip has a width of 6 mm and a thickness of 0.2 mm.
[0014] In some embodiments, the plurality of plate cells are square and distributed in an array.
[0015] In some embodiments, the auxiliary carrier further includes a plurality of water guide grooves, and the plurality of water guide grooves are disposed on opposite sides of the carrier plate.
[0016] In some embodiments, the step structure has a plurality of steps, and different steps have different lengths and / or different steps have different widths.
[0017] Compared with the prior art, the beneficial effects of the embodiments of the present application are:
[0018] An auxiliary carrier for PCBs passing through a horizontal production line provided in an embodiment of the present application can place thin plates or small-sized PCBs through the slots in the board placement cells without affecting the double-sided cleaning or surface treatment of the PCBs.

Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0024] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0026] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.
[0027] See also Figure 1 As shown, the embodiment of the present application provides an auxiliary carrier for PCB horizontal production line. When the original horizontal line process capacity is insufficient, the surface treatment horizontal line or cleaning line can be used to produce thin plates or small-sized plates, thereby saving 2-3 people per shift and saving tape. At the same time, it also greatly reduces the labor intensity of employees and improves work efficiency.
[0028] It should be noted that the thin plate described in the embodiment of the present application refers to a PCB with a thickness of ≤0.4 mm.
[0029] like Figure 1 The auxiliary carrier for PCB horizontal production line includes a carrier board 1, for example, the carrier board 1 is a copper-free substrate with a width of ≤500mm and a length of ≤600mm.
[0030] The carrier 1 is provided with a plurality of board placement cells 3, which are square and arranged in an array. The board placement cells 3 are used to place formed thin plates or small plates. For example, the length of the board placement cell 3 is equal to the length of the PCB plus 2 mm, and the width of the board placement cell 3 is equal to the width of the PCB plus 2 mm. Such a setting is convenient for placing and receiving the PCB.
[0031] As an example, the board placement unit cell 3 includes a slot 4 that penetrates the carrier board 1, and the side wall of the slot 4 is provided with a step structure for carrying the PCB. For example, the step structure includes at least one step, and the sizes of different steps are different, and can be used to place PCBs of different sizes. For example, the lengths of different steps are different and / or the widths of different steps are different.
[0032] As an example, the difference between the thickness of the carrier board 1 and the thickness of the step structure is greater than the thickness of the PCB. This arrangement allows the PCB to have a small movable space in the vertical direction, which facilitates the drying of the PCB and prevents the roller from bringing out the thin plate.
[0033] As an example, D≥a+b+0.6mm, where D is the thickness of the carrier 1, a is the thickness of the PCB, and b is the thickness of the step structure. This arrangement allows the PCB to have a 0.6mm activity space in the vertical direction.
[0034] As an example, the step structure includes a step for placing a PCB of a certain size, and the thickness of the step structure is 1 mm.
[0035] As an example, the spacing between adjacent board placement cells 3 is 8 mm, which is used to facilitate PCB board collection after demoulding.
[0036] As an example, the auxiliary carrier further includes a plurality of water guide grooves 2, which are arranged on opposite sides of the carrier board 1 for drainage, so as to facilitate drying of the PCB.
[0037] As an example, a baffle strip 5 is further provided on the card slot 4. For example, the width of the baffle strip 5 is 6 mm, the thickness is 0.2 mm, and D≥a+b+0.6 mm, so that there is at least 0.4 mm distance between the baffle strip 5 and the PCB, which is convenient for PCB cleaning and can also prevent the PCB from falling into the liquid medicine tank.
[0038] The working principle of an auxiliary carrier for PCB horizontal production line provided in the embodiment of the present application is as follows:
[0039] When in use, the formed small-sized or thinner PCBs are placed one by one in the card slots 4 of the board placement cells 3 until the board placement cells 3 are full. The auxiliary carrier and the PCB are placed together in the finished product cleaning horizontal line or the surface treatment horizontal line for processing. After the production is completed, the PCB in the auxiliary carrier is taken out. When the process is completed, the next production process is entered.
[0040] To sum up, the embodiment of the present application provides an auxiliary carrier for PCB horizontal production line. When the original horizontal line process capacity is insufficient, the auxiliary carrier can be used to achieve the purpose of normal production of the surface treatment horizontal line or cleaning line for the formed thin plates or small plates of PCB, thereby saving manpower of 2-3 people per shift and saving tape, and at the same time greatly reduces the labor intensity of employees and improves production efficiency.
[0041] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
