In the embodiment, the base assembly is driven by the driving assembly to rotate; in one depainting cycle, 4 network transformers 300 can be placed at the same time in the present embodiment, although in different embodiments, the number of network transformers 300 to be placed can be determined according to specific situations.

In the embodiment, the base is fixed on the external table body, so that the object placing seat 2 is effectively supported; when the power device 3 gives power to the driving mechanism, the driving mechanism drives the object placing seat 2 to rotate.

For better use of the present embodiment, the driving mechanism comprises a driving wheel 4, a driving rod 5 and a driven wheel 6; the driving wheel 4 is arranged at the driving end of the power equipment 3; the driving rod 5 is rotatably connected with the base body 1 and fixedly connected with the object placing base 2; the driven wheel 6 is arranged at one end of the driving rod 5; the rotation of the driven wheel 6 is driven by the driving wheel 4.

In the embodiment, in order to better and reasonably utilize the actual available area of the external table body, the driving wheel 4, the driving rod 5 and the driven wheel 6 are used as intermediate pieces to realize transition control.

In fact, the seat body 1 has two connecting holes, which are provided with bearings, and two ends of the driving rod 5 are respectively connected with the two connecting holes in a rotating manner, that is, the driving rod 5 can rotate along the central axis thereof; and put thing seat 2 and have two other connecting holes, and the both ends of actuating lever 5 respectively with these two other connecting holes fixed connection, consequently, by the rotation of actuating lever 5, the thing seat 2 rotation is put in the drive that can be fine to with the pedestal 1 all realized fine supporting role to putting thing seat 2 and actuating lever 5.

In other embodiments, the driving wheel 4 and the driven wheel 6 are gears, and the driving wheel 4 and the driven wheel 6 are meshed with each other to realize the rotation of the driving rod 5; on the basis, in order to better utilize the space of the device, some embodiments utilize a chain to connect the driving wheel 4 and the driven wheel 6, and the rotation of the driving rod 5 can be well realized.

In the present embodiment, the power device 3 is a stepping motor. It should be noted that, the present embodiment has a control system, which is generally a computer; the rotation angle of the stepping motor is controlled by programming a corresponding program into the computer, so that the rotation precision is met. After passing through not more than five cycles, the computer controls the stepping motor to reset, so that the rotation precision of the stepping motor is ensured, and the requirement of the laser device 100 on the position precision is met.

It should be noted that, one end of the lower portion of the storage seat 2 is provided with an induction sheet 8, and the base is provided with an inductor 9 for inducing the position of the sheet 8, when the induction sheet 8 cuts the magnetic field provided by the inductor 9, the inductor 9 outputs a signal to the computer, so that the computer obtains the position of the storage seat 2. This enables the beginning and end of each rollover cycle to be determined, as well as whether a reset is implemented.

In order to better use the embodiment, the storage seat 2 is provided with a sliding chute 10, and the network transformer 300 slides in the sliding chute 10; the chute 10 is provided with a stop member for limiting the movement of the network transformer 300; the sliding groove 10 is provided with an avoiding groove for avoiding interference of an assembly pin of the network transformer 300 on the sliding of the network transformer 300 in the sliding groove 10; the sliding chute 10 is divided into two avoiding grooves in the length direction of the sliding chute 10 through a limiting plate 11; step platforms 12 are respectively arranged on two sides of the sliding groove 10; the network transformer 300 is supported by the step 12 and slides on the step 12.

After the network transformer 300 enters the chute 10, the assembly pin pins on two sides of the network transformer respectively slide in two parts corresponding to the chute 10, so that interference of the assembly pin pins on the sliding of the network transformer 300 is avoided, and damage of the assembly pin pins caused by the sliding interference is also avoided. In the present embodiment, both sides of the network transformer 300 are supported by the step platform 12 to slide, thereby dispersing the supporting force to both sides of the network transformer 300, and thus the sliding to the network transformer 300 is more stable. In some embodiments, the avoiding grooves are disposed on both sides of the sliding groove 10 for different network transformers 300, i.e. the grooves are separately formed.

For better use of the present embodiment, the limiting plate 11 is made of a magnetic material, and the limiting plate 11 and the network transformer 300 are attracted to each other; that is, in the present embodiment, the stop member is the stop plate 11.

Due to the attraction between the limiting plate 11 and the network transformer 300, the network transformer 300 can be kept relatively still when not being driven by the external rod, so that the position accuracy requirement of the laser device 100 can be met when the object placing seat 2 rotates.

In this embodiment, the upper plane of the limit plate 11 is flush with the upper plane of the landing 12, that is, after the network transformer 300 enters the chute 10, the network transformer 300 contacts the limit plate 11, so that the attraction force between the network transformer 300 and the limit plate 11 is the greatest; in other embodiments, the upper plane of the position-limiting plate 11 is lower than the upper plane of the step platform 12, so that the attraction force is smaller and the position stability is poorer than in the embodiment in which the upper planes of the two are flush with each other. It should be noted that the upper plane of the position limiting plate 11 should not be higher than the upper plane of the step 12, so that the network transformer 300 is supported by the position limiting plate 11, and when the external rod drives the network transformer 300, the network transformer 300 is easily displaced, thereby being disadvantageous to the burning of the laser device 100.

The paint stripping method used in this example comprises the following steps:

s100, placing the network transformer 300 into the turnover device 200, wherein the turnover device is located at a first position;

s200, connecting a pin to one row of the network transformer 300 by using the laser equipment 100, and stripping paint;

s300, rotating the turnover device 200 to enable the network transformer 300 to be located at a second position;

s400, stripping paint from the stranded wire points corresponding to the pin pins by using the laser equipment 100;

s500, rotating the turnover device 200 to enable the network transformer 300 to be located at a third position;

s600, stripping paint from a stranded wire point corresponding to the other flat cable pin by using the laser equipment 100;

s700, rotating the turnover device 200 to enable the network transformer 300 to return to the first position;

s800, stripping paint from the row of pin pins by using the laser equipment 100;

and S900, moving the network transformer 300 out of the turnover device 200.

And S1000, resetting for 1 time after the turnover device 200 carries out 4 times of circulating turnover.

It should be noted that, in the present embodiment, the first position is generally a horizontal position, and the second position and the third position are planes having an inclination angle with respect to the horizontal plane; the inclination angles of the second position and the third position can be set by actual conditions, and exact rotation angles can be obtained after limited experiments of workers.

In this embodiment, S100 to S900 are cyclically inverted once. In addition, in the method, the time consumed by S100-S900 is not more than 3.5S, so that the requirement of less burning time at low temperature is met on the basis of higher paint removing efficiency and better effect, and the efficiency of the paint removing process is further improved. In the present embodiment, the time taken for S100 to S900 is 3.3S.

If the laser apparatus 100 is a conventional laser apparatus 100, the time taken for S100 to S900 to be satisfied should be not more than 3S. Because the temperature provided by the conventional laser apparatus 100 is 400 ℃, and thus the temperature is higher than that of the laser apparatus, the time consumed by the conventional laser apparatus 100 should be as short as possible, and generally, if the conventional laser apparatus 100 is used, the time consumed by S100 to S900 is 2S. On this basis, the cycle rhythm is too fast, which is not favorable for long-term use of the paint stripping device, and the interval time between maintenance periods of the paint stripping device is correspondingly shortened, thereby reducing the production efficiency.

The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and these modifications and adaptations should be considered within the scope of the invention.
