DETAILED DESCRIPTION

[0033] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Example

[0035] like Figure 1-3 As shown, on the one hand, the present invention proposes a surface treatment device for processing automotive electronic parts, including a base 1, and also including multiple groups of pressure self-adjusting mechanisms installed on the base 1, on which a brush head 206 is installed, and the pressure adjustment mechanism adjusts the distance between the brush head 206 and the surface of the part according to the shape of the part surface. By setting multiple brush heads 206 and adjusting the heights of the multiple brush heads 206 according to the concave and convex conditions of the surface of the electronic part, it can be ensured that the pressure applied by the brush head 206 to various parts of the electronic part is kept within a suitable range, so as to improve the cleaning effect and prevent damage to the electronic part. Transmission shafts 2 are rotatably installed on both sides of the base 1, and slideways 201 are fixedly installed on the transmission shafts 2. A support frame 202 is slidably installed in the slideway 201, and the pressure self-adjusting mechanism is installed inside the support frame 202.

[0036] Furthermore, the pressure self-adjusting mechanism includes a first connecting rod 203 and a second connecting rod 204 slidably installed in the support frame 202, the first connecting rod 203 and the second connecting rod 204 are in a coaxial position, the first connecting rod 203 is rotatably installed with a sensing wheel 205, the brush head 206 is fixedly installed on the second connecting rod 204, an adjusting rod 208 is rotatably installed between the first connecting rod 203 and the second connecting rod 204, a reference shaft 207 is rotatably installed in the support frame 202, and the adjusting rod 208 is fixedly connected to the reference shaft 207. When the uneven electronic accessories come into contact with the induction wheel 205, the induction wheel 205 will be driven to rise, and the rising height depends on the height of the surface of the electronic accessories. When the induction wheel 205 drives the first connecting rod 203 to rise, it will drive the adjusting rod 208 to rotate, and the rotating adjusting rod 208 will drive the second connecting rod 204 to descend, and then drive the brush head 206 to descend, so that the extension distance of the brush head 206 can be reduced as the surface of the electronic accessories protrudes, so that the brush head 206 can adapt to the uneven electronic accessories, and the pressure applied by the brush head 206 to various positions of the electronic accessories can be kept within an appropriate range.

[0037] Furthermore, a locking mechanism for limiting the reference shaft 207 is installed on the support frame 202. The locking mechanism includes a first friction plate 3 fixedly installed at one end of the reference shaft 207, the first friction plate 3 is located outside the support frame 202, a support plate 301 on the support frame 202, a first push rod motor 302 is fixedly installed on the support plate 301, a cross plate 303 is fixedly installed on the output shaft of the first push rod motor 302, and a plurality of second friction plates 304 are fixedly installed on the cross plate 303, and the second friction plates 304 correspond to the first friction plates 3 one by one and are in a coaxial position. When the position of the brush head 206 is adjusted, the first push rod motor 302 is started, and the first push rod motor 302 will drive the second friction plates 304 to move in a direction close to the first friction plate 3, so that the second friction plates 304 clamp and fix the first friction plates 3, thereby preventing the reference shaft 207 from rotating, thereby preventing the length of the brush head 206 from changing.

[0038] Among them, a transmission plate 4 is fixedly installed between the two slideways 201, a first motor 401 is fixedly installed on the base 1, and the output shaft of the first motor 401 is coaxially fixedly connected with one of the transmission shafts 2. The transmission shaft 2 can be driven to rotate by the first motor 401, and the two slideways 201 can be rotated by the transmission plate 4, so that the positions of the induction wheel 205 and the brush head 206 can be exchanged, so that the brush head 206 with adjusted position can contact the electronic accessories. A screw rod 5 is rotatably installed in the slideway 201, and a transmission belt 501 is fixedly installed on the two screw rods 5. A second motor 502 is fixedly installed on one of the slideways 201, and the output shaft of the second motor 502 is coaxially fixedly connected with one of the screw rods 5. When the second motor 502 rotates, it will drive the screw rod 5 connected thereto to rotate, and the two screw rods 5 can be rotated synchronously through the transmission belt 501, thereby driving the support frame 202 to slide along the slide 201, and then driving the brush head 206 to move, so that the brush head 206 cleans the electronic accessories.

[0039] like Figure 3 and Figure 4-6 As shown, this embodiment also includes an air suction fixing mechanism, which is installed on the base 1. The air suction fixing mechanism includes a plurality of air holes 601. The air suction fixing mechanism is provided with a blocking mechanism that automatically blocks the air holes 601 according to the position of the accessories. The opening range of the air holes 601 can be automatically adjusted according to the area of ​​the electronic accessories. A plurality of first telescopic rods 8 and a second push rod motor 801 are fixedly installed on the base 1. The air suction fixing mechanism includes an air box 6 installed on the output shaft of the second push rod motor 801 and the other end of the first telescopic rod 8. The air holes 601 are evenly arranged on the upper surface of the air box 6. A connector 602 is fixedly installed on one side of the air box 6. The connector 602 is fixedly connected to the air pump through an air pipe. The air pump can be used to apply negative pressure to the air box 6, so that the air holes 601 generate adsorption force to the outside world, and the electronic accessories can be adsorbed on the surface of the air box 6. When the second push rod motor 801 drives the air box 6 to rise, the electronic accessories can be driven to rise, so that the electronic accessories can be brought into contact with the induction wheel 205.

[0040] Furthermore, the blocking mechanism includes a mounting seat 7 fixedly installed in the air box 6 and located below the air hole 601, a second telescopic rod 701 and a first spring 702 are fixedly installed on the mounting seat 7, a limiting column 703 is fixedly installed on the other end of the first spring 702 and the second telescopic rod 701, a cavity 704 is provided in the limiting column 703, a third telescopic rod 705 and a second spring 706 are fixedly installed in the cavity 704, a driving block 707 is fixedly installed on the other end of the third telescopic rod 705 and the second spring 706, a plurality of limiting blocks 708 are slidably installed in the limiting column 703, a plurality of limiting holes corresponding to the limiting blocks 708 are provided on the air box 6 and located in the air hole 601, a connecting rod 709 is rotatably installed between the limiting block 708 and the driving block 707, a pressing rod 710 is fixedly installed on the driving block 707, and the other end of the pressing rod 710 passes through the top of the limiting column 703 and extends to the outside of the limiting column 703. When the electronic accessories are placed on the air box 6, the electronic accessories will press down the pressure rod 710 in contact with it under the action of gravity. The descending pressure rod 710 will drive the driving block 707 to descend and compress the second spring 706. At this time, the driving block 707 will drive the connecting rod 709 to rotate, and the rotating connecting rod 709 will drive the limit block 708 to disengage from the limit groove. At this time, the electronic accessories that continue to move downward will drive the limit column 703 to continue to descend. At this time, the first spring 702 is compressed, and the descending limit column 703 will not be able to block the air hole 601. At this time, the air hole 601 can generate suction to the outside world. When the electronic accessories are taken out, the limit column 703, the pressure rod 710 and the limit block 708 will be reset under the action of the first spring 702 and the second spring 706.

[0041] The pressure rod 710 that is not in contact with the electronic accessories will remain in its original state. At this time, the limit block 708 is located in the limit groove, so that the negative pressure inside the air box 6 cannot move the limit column 703 downward, thereby ensuring the stability of the sealing of the air hole 601.

[0042] On the other hand, the present invention provides a surface treatment method for automotive electronic parts, which is applied to the above-mentioned surface treatment device for automotive electronic parts processing, and the method comprises the following steps:

[0043] Step 1: Place the power distribution on the gas box 6, and under the gravity of the accessories, the limiting column 703 pressed by the accessories will be driven down to make the air hole 601 connected with the outside;

[0044] Step 2: The air box is subjected to negative pressure under the action of the air pump, and suction is generated on the accessories through the air holes 601 to complete the fixing of the accessories;

[0045] Step 3: The air box 6 is driven upward by the second push rod motor 801, so that the accessory contacts the induction wheel 205, and drives the induction wheel 205 to rise;

[0046] Step 4: The brush head 206 is driven to move by the movement of the induction wheel 205, so that different brush heads correspond to different concave and convex positions of the accessories;

[0047] Step 5: The second friction plate 304 is brought into contact with the first friction plate 3 by the first push rod motor 302 to fix the position of the brush head 206;

[0048] Step 6: The first motor 401 drives the brush head 206 to flip so that the brush head 206 contacts the accessory;

[0049] Step 7: The second motor 502 drives the brush head 206 to move back and forth, so that the brush head 206 cleans the accessories.

[0050] The working principle of this embodiment is as follows: when the electronic accessory is placed on the air box 6, the electronic accessory will drive the driving block 707 to descend, and the driving block 707 will drive the connecting rod 709 to rotate. The rotating connecting rod 709 will drive the limiting block 708 to disengage from the limiting groove. At this time, the electronic accessory that continues to move downward will drive the limiting column 703 to continue to descend. The descending limiting column 703 will not be able to block the air hole 601. At this time, the air hole 601 can generate suction to the outside world, so that the electronic accessory is fixed on the air box 6. The second push rod motor 801 drives the air box 6 to rise, which can drive the electronic accessory to rise, so that the electronic accessory can contact the induction wheel 205. When the uneven electronic accessories come into contact with the induction wheel 205, the induction wheel 205 will be driven to rise, and the adjustment rod 208 will be driven to rotate. The rotating adjustment rod 208 will drive the second connecting rod 204 to descend, and then drive the brush head 206 to descend, so that the extension distance of the brush head 206 can be reduced as the surface of the electronic accessories protrudes, so that the brush head 206 can adapt to the uneven electronic accessories, and the pressure applied by the brush head 206 to each position of the electronic accessories can be kept within a suitable range. After the position of the brush head 206 is adjusted, the first push rod motor 302 is started, so that the second friction plate 304 clamps and fixes the first friction plate 3, thereby preventing the reference shaft 207 from rotating, thereby preventing the extension length of the brush head 206 from changing. The transmission shaft 2 can be driven to rotate by the first motor 401, and the positions of the induction wheel 205 and the brush head 206 can be exchanged, so that the brush head 206 after the position adjustment comes into contact with the electronic accessories. The second motor 502 of the bronze drum drives the support frame 202 to slide along the slideway 201, thereby driving the brush head 206 to move, so that the brush head 206 cleans the electronic accessories.

[0051] The above specific embodiments are only several optional embodiments of the present invention.
