Description
Technical Field
The patent relates to the technical field of PCB (printed circuit board) grinding, in particular to an abrasive belt grinding equipment method.
Background
Grinding the surface of the PCB board, and dividing the grinding into single-sided grinding and double-sided grinding according to different requirements. The prior PCB abrasive belt grinding equipment is generally divided into single-sided abrasive belt grinding equipment and double-sided abrasive belt opposite grinding equipment. The single-side abrasive belt grinding equipment is only suitable for single-side grinding of the PCB, and the PCB needs to be ground on two sides by two single-side abrasive belt grinding equipment and the plate turning equipment, so that the operation is complicated, the inconvenience is high, and the efficiency is low. The double-sided abrasive belt is suitable for double-sided grinding of a PCB (printed circuit board), but the double-sided abrasive belt is poor in adaptability when the double-sided abrasive belt is used for single-sided grinding, and due to the fact that the back pressure roller is not used for supporting the plate, the plate deforms when the single side of the plate is pressed, and particularly for a thin plate, the plate deforms more obviously, so that the grinding effect is poor, and products are unqualified when the plate is serious.
Therefore, the prior PCB abrasive belt grinding equipment has single function, and the task of processing double-sided grinding by using single-sided grinding equipment or the task of processing single-sided grinding by using double-sided grinding equipment has poor effect.
On the other hand, before double-side grinding, a grinding process is often required to flatten the board, for example, if the printed circuit board has a specially raised ink on one side after plugging the hole, single-side grinding is required to be performed first to remove the excess ink, then double-side grinding is performed to remove the residual ink and the surface oxidation layer, so that general enterprises generally use one single-side grinding device and one double-side opposite grinding device or use two double-side opposite grinding devices to combine.
For the above reasons, general enterprises need to combine two devices to meet the production requirements, which results in high cost, large floor area, low processing efficiency, and inability to meet the requirements of mass production.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects of the prior art, the technical problem to be solved by the patent is to provide abrasive belt grinding equipment which can be used for single-side grinding and double-side grinding. This patent has adopted such technical scheme:
the abrasive belt grinding equipment comprises a rack and a conveying mechanism of a to-be-ground part, and is characterized in that a single-side grinding mechanism and a double-side grinding mechanism are arranged in the rack, the single-side grinding mechanism comprises a first upper abrasive belt grinding component and a back pressure roller component, and the double-side grinding mechanism comprises a second upper abrasive belt grinding component and a second lower abrasive belt grinding component.
The abrasive belt grinding equipment also comprises a control mechanism, wherein the control mechanism can control the first upper abrasive belt grinding component and the second upper abrasive belt grinding component to lift up or press down, so that the single-side grinding mechanism and the double-side grinding mechanism enter a non-working state or a working state, and single-side grinding, double-side grinding or single-side and double-side grinding are realized according to actual requirements. And preferably, the conveying mechanism of the workpiece to be ground penetrates through the rack and conveys the workpiece through the single-side grinding mechanism and the double-side grinding mechanism in sequence.
When the double-sided grinding is carried out, the single-sided grinding mechanism can carry out pretreatment grinding before the double-sided grinding process, and is suitable for special condition treatment. For example, in response to the situation that one side of the circuit board has special convex ink after hole plugging, the single-side grinding and double-side grinding treatment is adopted: the PCB to be ground is firstly ground on one side by a single-side grinding mechanism, redundant printing ink is removed, and then the PCB to be ground is ground on two sides by a double-side grinding mechanism.
This patent is to single face grinding device and two-sided to grinding the grinding part combination of equipment to a grinding device on the pertinence, on the one hand can deal with various single face grinding tasks and two-sided grinding task in a flexible way, on the other hand, many other parts can share after the combination, for example only adopt a frame, one set of control mechanism, one set of measurement system, one set is waited to grind a conveying mechanism, greatly reduced equipment cost, and it shortens greatly to wait to grind a conveying mechanism total length, obviously reduce area, more importantly compresses the transfer time by a wide margin, and the improvement production efficiency satisfies the requirement of mass production. Can kill two birds with one stone, obtains obvious economic benefit and belongs to creative organic combination.
In summary, the innovation of the present invention over the prior art is:
(1) the equipment of the utility model has the functions of single-side grinding, double-side grinding and single-side and double-side combined grinding at the same time, and has strong adaptability to various grinding tasks.
(2) Compared with the combined use of two abrasive belt grinding devices with the same function, the device has the advantages of small occupied area, low device cost and high processing efficiency.
