Abstract
The utility model relates to device inclined device is prevented when a kind of wave crest, including substrate, the substrate is equipped with the circular hole for positioning capacitor, and the irregularly-shaped hole for positioning exclusion, the position of the capacitor for needing to weld in position, number and the size and printed circuit board of circular hole, number and cross sectional dimensions are consistent, and the position of the exclusion for needing to weld in position, number and the size and printed circuit board of irregularly-shaped hole, number and cross sectional dimensions are consistent.Compared with prior art, the utility model is by way of borehole, entangle the device on printed circuit board, device caused by acting on when wave-soldering because of wind-force is avoided to topple over, and since each device is entangled, and needs easy for installation are put on, and can greatly improve efficiency and quality in large-scale production.
Description
Technical field
The utility model relates to a kind of wave-soldering auxiliary devices, and device inclined dress is prevented when more particularly, to a kind of wave crest
It sets.
Background technique
In electronics processing industry, direct inserting device wave soldering mode is also generally existing, in wave soldering, often because
Inclination during wind-force effect generation, in this regard, existing technical staff needs that device is fixed, such as Chinese patent
CN206452617U discloses a kind of pcb board wave-soldering and crosses furnace carrier, by upper support plate and downloading board group at, it is characterised in that: institute
That states uploads board ends equipped with card slot, and centre is equipped with multiple springs and presses fixture block；Groove is equipped among the lower support plate, and recessed
The upper/lower terminal of slot is additionally provided with card base, is equipped with supporting block on the inside of card base；Workpiece is placed in groove, and upper support plate covers on lower support plate
It is supported by supporting block, spring pressure fixture block thereon compresses the component of workpiece, is fixed by card base and card slot cooperation, completion pair
The pressure of workpiece is pressed from both sides.However as the progress of technology, requirement of some products to wave-soldering is very high, especially K5B series of products, right
The neat degree of device requires very high after wave soldering, component is not fixed in wave crest such as, or uses such as above-mentioned
Mode simply fixed as furnace carrier is crossed, device position all can be irregular after wave crest, influences beauty.So wave soldering
The fixed device for being easy offset of specific tooling is needed before.There are many middle advance of product, press the fixed effect institute energy of folder mode
The wind-force undertaken is limited.
Utility model content
The purpose of this utility model be exactly in order to overcome the problems of the above-mentioned prior art and when a kind of wave crest is provided it is anti-
The only inclined device of device.
The purpose of this utility model can be achieved through the following technical solutions:
The inclined device of device, including substrate are prevented when a kind of wave crest, which is equipped with the circular hole for positioning capacitor,
And the irregularly-shaped hole for positioning exclusion, the electricity for needing to weld in position, number and the size of the circular hole and printed circuit board
The position of appearance, number are consistent with cross sectional dimensions, need to weld in position, number and the size and printed circuit board of the irregularly-shaped hole
The position of the exclusion connect, number are consistent with cross sectional dimensions.
The substrate is the steel plate with a thickness of 1.5~3 millimeters.
The substrate with a thickness of 2 millimeters.
The irregularly-shaped hole is in long strip, and which is provided with protrusion.
The card slot for being surrounded by multiple fixations of the substrate.
Described device further includes multiple fixtures, which includes support matrix and the collet set on matrix two sides.
Compared with prior art, the utility model has the following beneficial effects:
1) by way of borehole, the device on printed circuit board is entangled, avoids causing when wave-soldering because of wind-force effect
Device topple over, and since each device is entangled, and needs easy for installation are put on, in large-scale production
Efficiency and quality can be greatly improved.
2) steel plate, especially stainless steel plate are used, structural strength is high, and overturning-preventing effect is good.
3) card slot is additionally set, convenient for substrate is fixed.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein: 1, substrate, 2, circular hole, 3, irregularly-shaped hole.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model
Shield range is not limited to the following embodiments.
Device inclined device is prevented when a kind of wave crest, as shown in Figure 1, including substrate 1, which is equipped with for fixed
The circular hole 2 of position capacitor, and the irregularly-shaped hole 3 for positioning exclusion, in the position of circular hole 2, number and size and printed circuit board
The position for the capacitor for needing to weld, number are consistent with cross sectional dimensions, position, number and the size and printed circuit of irregularly-shaped hole 3
The position for the exclusion for needing to weld on plate, number are consistent with cross sectional dimensions.
By way of borehole, the device on printed circuit board is entangled, is avoided caused by being acted on when wave-soldering because of wind-force
Device is toppled over, and since each device is entangled, and needs easy for installation are put on, can in large-scale production
To greatly improve efficiency and quality.
Substrate 1 is with a thickness of 1.5~3 millimeters of steel plate, it is preferred that substrate 1 with a thickness of 2 millimeters, it is stainless using 2mm
Steel has good intensity, toughness.Steel plate internal notches.Circular hole 2 is slotted according to capacitor size, and irregularly-shaped hole 3 is according to exclusion size
Fluting, wherein irregularly-shaped hole 3 is in long strip, and which is provided with protrusion.
The card slot 4 for being surrounded by multiple fixations of substrate 1, device further include multiple fixtures, which includes that support is used
Matrix and collet set on matrix two sides, consequently facilitating fixed.Specifically, the form that can be used first is that: matrix is located at
Substrate 1 is used to support between printed circuit board and substrate 1, two collets clamp printed circuit board and substrate 1 respectively, for clamping
The collet of printed circuit board is the cylinder that size is less than matrix, can pass through the location hole on printed circuit board.
