The embodiment provides a paint stripping device which can be used for stripping a paint layer of a processed element such as an inductor and the like, and can identify the spatial position of each processed element before paint stripping operation, so that a paint stripping mechanism can accurately perform paint stripping treatment on a paint area to be stripped of each processed element. The following describes the paint stripping device in detail by taking the pin paint stripping operation of the inductor as an example:

referring to fig. 2, the paint stripping apparatus includes a work table 1, a feeding mechanism 2, a transferring mechanism 3, a discharging mechanism (not shown), and a paint stripping mechanism 4. The work table 1 has at least two processing stations. The feeding mechanism 2 can alternately move the jig 5 fixed with the inductor 100 to be stripped into each processing station. A paint stripping mechanism 4 is fixed at the movable end of the transfer mechanism 3, so that the paint stripping mechanism 4 can be alternately moved to be opposite to each processing station to strip a paint layer on the surface of the inductor 100; the blanking mechanism can alternately move the jigs 5 which are loaded at each processing station and finish paint stripping treatment out of the workbench 1.

The feeding mechanism 2 comprises a first conveyor belt 21 arranged next to the workbench 1, and the first conveyor belt 21 is used for conveying the jig 5. The feeding mechanism 2 further comprises a first transfer part 22 and a second transfer part 23, wherein the movable end of the first transfer part 22 can horizontally reciprocate between the first conveyor belt 21 and the workbench 1; the second transfer part 23 is fixed to a movable end of the first transfer part 22, and a push block 24 is fixed to the movable end thereof and serves to lift or lower the push block 24 in a vertical direction. The blanking mechanism can comprise a second conveyor belt and a blanking cylinder, wherein the second conveyor belt is located on the opposite side of the first conveyor belt 21 and is also close to the workbench 1, and the blanking cylinder can push the jig 5 to the second conveyor belt from the processing station. Alternatively, the blanking mechanism may also be a plurality of manipulators arranged adjacent to the workbench 1, and the manipulators are used for carrying the jigs 5. Of course, the paint stripping device provided in this embodiment may also adopt a manual blanking manner without configuring a blanking mechanism, and is not limited herein.

Taking the example of fig. 1 in which two processing stations are disposed on the workbench 1, during operation, the first conveyor belt 21 alternately conveys one jig 5 to be opposite to the two processing stations, or conveys two jigs 5 to be respectively opposite to the two processing stations at the same time, the first transfer portion 22 moves the second transfer portion 23 to the outer side of the first conveyor belt 21, the second transfer portion 23 descends to push the block 24 to abut against the side edge of the jig 5 on the first conveyor belt 21, the first transfer portion 22 moves in the reverse direction to push the jig 5 to the processing stations, so as to complete loading, and then the first transfer portion 22 moves the second transfer portion 23 in the reverse direction to perform the next loading operation. The moving and carrying mechanism 3 composed of a mechanical arm, a multi-axis module and the like drives the paint stripping mechanism 4 to alternatively strip the paint on the inductor 100 fixed in the jig 5 at each station, thereby realizing uninterrupted paint stripping operation and improving the working efficiency.

For example, if the feeding time of the feeding mechanism 2 is shorter than the time for the paint stripping mechanism 4 to complete the paint stripping operation of the inductor 100 on the single jig 5, only two processing stations need to be configured on the workbench 1 to realize the uninterrupted processing of the paint stripping mechanism 4.

In order to enable the feeding mechanism 2 to accurately provide the jigs 5 to each processing station at a time, detection elements such as photoelectric switches corresponding to the processing stations can be arranged on the side of the first conveyor belt 21, the photoelectric switches are electrically connected with the first conveyor belt 21, and the first conveyor belt 2 is stopped after the jigs 5 on the first conveyor belt 21 reach a specified position and trigger the photoelectric switches.

In this embodiment, the jig 5 is preferably capable of fixing a plurality of inductors 100, so that the paint stripping mechanism 4 can process a plurality of inductors 100 in a single operation, thereby improving the paint stripping efficiency.

And in order to be convenient for the paint stripping mechanism 4 to accurately strip the paint on the area to be stripped of each inductor 100, the paint stripping device further comprises an identification mechanism 6, the identification mechanism 6 is in communication connection with the paint stripping mechanism 4 and is configured to identify the spatial position of each inductor 100 on the jig 5, and the paint stripping mechanism 4 can strip the paint layer on the preset area on the surface of the processed element according to the identified position. The predetermined area is a lead area of the surface of the inductor 100, where the paint layer needs to be stripped, and as shown by a shaded area in fig. 3, the predetermined area preferably does not extend to the edge of the lead side of the inductor 100, so as to avoid situations such as uncertain outflow of solder paste for soldering the inductor 100 after the inductor 100 is mounted on a PCB.

By means of the recognition mechanism 6, after the jig 5 and the spatial position information of the inductors 100 fixed on the jig are processed by common coordinate calibration software and the like, the coordinate information of the positions of the inductors 100 which need to be stripped is fed back to the controllers such as PL3 and the like which control the movement of the transfer mechanism 3 and the paint stripping mechanism 4 through IO signal communication, so that the transfer mechanism 3 and the paint stripping mechanism 4 can accurately strip the paint on the areas of the inductors 100 to be stripped under the control of the controllers. The dimensional parameters of the inductor 100 and the corresponding jig 5 and the like which need to be subjected to paint stripping treatment are recorded in the calibration software in advance, so that the preparation links of manual debugging, equipment position parameter adjustment and the like before each paint stripping operation can be omitted.

In this embodiment, shell lacquer mechanism 4 and adopt laser to shell lacquer equipment, move and carry the translation mechanism that the elevating system 31 that mechanism 3 includes a vertical setting and a level set up, the orientation of arranging of inductance 100 in the parallel tool 5 of extending direction of translation mechanism, translation mechanism's stiff end links firmly with elevating system 31's expansion end, translation mechanism's expansion end links firmly with adjustment laser shell lacquer equipment, in order to promote or descend this adjustment laser through elevating system 31 and shell lacquer equipment, the facula size that the laser that adjustment laser shell lacquer equipment jetted out falls on inductance 100, and shell each inductance 100 of lacquer equipment translation processing through translation mechanism drive laser.

Specifically, the lifting mechanism 31 and the translation mechanism may include a screw nut pair and a motor or a crank that can drive the screw to rotate, and the structure of the screw nut pair is not described herein.

Of course, in some alternative embodiments, the laser paint stripping apparatus may be provided with an adjusting mechanism capable of adjusting the laser emitting position/direction, and the adjusting mechanism may be used to replace the transferring mechanism partially or completely. The laser paint stripping device equipped with the adjusting mechanism is already used in the prior art, and is not described herein.

As shown in fig. 3, after the inductors 100 are calibrated by the recognition mechanism 6, the paint stripping mechanism 4 may only strip paint from the predetermined area to avoid gaps between adjacent inductors 100, so as to avoid damage to the jig 5 by the laser passing through the gaps when the paint stripping device is used as the paint stripping mechanism 4.

Specifically, the recognition mechanism 6 may preferably employ a CCD industrial camera, so as to be beneficial to obtaining the accurate spatial position of each inductor 100 in the fixture 5 based on the existing mature calibration software, and the like, and the CCD industrial cameras may be provided in plurality, and the plurality of CCD industrial cameras correspond to each processing station respectively. The circuit connection and communication methods of the controller, the identification mechanism 6, the transfer mechanism 3, the paint stripping mechanism 4 and other components, and the setting, debugging and the like of the calibration software are widely applied in the field of automatic processing, and are not described herein again.

In order to facilitate the paint stripping mechanism 4 to rapidly process the plurality of inductors 100 on the single jig 5, in this embodiment, the plurality of inductors 100 fixed on the jig 5 may be arranged side by side with the edge being flush, so that all the inductors 100 are closely and regularly placed, and thus the identification mechanism 6 may identify the contour lines of the inductors 100 and determine the spatial positions of the inductors 100 based on the preset size parameters of the inductors 100.

Specifically, for facilitating loading and fixing the inductor 100, as shown in fig. 3, the jig 5 may include a jig body 51 and a blocking portion 52. The jig main body 51 has a receiving groove 53 extending linearly along the surface thereof, a plurality of elements to be processed can be received in the receiving groove 53 in parallel, and one end of the receiving groove 53 extends to the end surface of the jig 5. The blocking portion 52 is detachably connected to the jig 5 to block the connection between the accommodating groove 53 and the end surface.

It is understood that the width of the slot 53 may be equal to or slightly larger than the width of the inductor 100, so that the slot 53 forms a clearance fit with the inductor 100, and particularly, the plurality of inductors 100 are generally integrally placed in the slot 53. The vessel 53 may be provided in plural, and the plural vessels 53 are preferably arranged in parallel.

Preferably, in order to make the plurality of inductors 100 in the accommodating groove 53 tightly contact with each other so as to make the posture of the inductor 100 regular and obtain a clear boundary line, the jig 5 may further include an elastic element 54, and the elastic element 54 is fixed at a position opposite to the blocking portion 52 and the accommodating groove 53 so as to press and tightly contact the plurality of inductors 100 in the accommodating groove 53 when the blocking portion 52 is connected to the jig body 51.

The mechanism 6 for identifying the coordinate calibration requirement based on vision acquires clear images of the fixture 5 and the inductor 100, and the accuracy of the calibration information needs to consider the fixture 5 and the inductor 100 of the acquired image besides the fault tolerance and the image analysis capability of the calibration software algorithm, taking the judgment basis that the contour line of each inductor 100 is acquired as the space position of the inductor 100 in the embodiment as an example, if impurities fall on the critical position between adjacent inductors 100, the edge contour of the inductor 100 can be misjudged possibly, and the accuracy of paint stripping processing is further influenced.

For this reason, in the present embodiment, the paint stripping apparatus may further include a cleaning mechanism configured to clean the inductor 100 fixed to the jig 5. That is, before the paint stripping operation, the cleaning mechanism cleans the surface of the inductor 100 to remove impurities possibly remaining on the surface of the inductor 100, so as to ensure the accuracy of the subsequent calibration of the inductor 100.

Alternatively, the cleaning mechanism may be a brush roller or an air knife or the like provided at the periphery of the processing station. Taking the air knife as an example, the air knife may be specifically disposed on one side of the feeding path of the feeding mechanism 2, so as to purge the surface of the inductor 100 during the process that the feeding mechanism 2 moves the jig 5 to each processing station.

Specifically, referring to fig. 4, in the present embodiment, the cleaning mechanism includes an air blowing portion 7 capable of moving relative to the jig 5. The air blowing part 7 is integrated with the pushing block 24 and specifically comprises an air hole 71 formed in the pushing block 24, the air hole 71 extends to the bottom surface of the pushing block 24 and is communicated with an external air source air path, so that when the feeding mechanism 2 moves to enable the pushing block 24 to be located above the jig 5, air blown out of the air hole 71 can blow the inductor 100 fixed on the jig 5.

Preferably, the blowing unit 7 may be configured to operate during a return process after the feeding operation is completed, that is, when the first transfer unit 22 drives the second transfer unit 23 to move to the outside of the first conveyor belt 21 and pass over the first conveyor belt 21, the jig 5 located on the first conveyor belt 21 and to be transferred to the processing station by the feeding mechanism 2 is purged, so that the purging process does not take extra time.

Preferably, the extending direction of the air hole 71 intersects with the horizontal plane to incline the purging fixture 5, so that the surface of the inductor 100 fixed on the fixture 5 is effectively purged.

Further, the gas blowing direction of the gas hole 71 can be back to the processing station, that is, impurities on the surface of the inductor 100 or the jig 5 are blown and raised and then move back to the processing station, so that the impurities are prevented from falling into the processing station or polluting a view finding lens of the recognition mechanism 6.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
