[0025] Referring to Figures 1 to 3 As shown, a tool for silicon grease coating of a plate of the present utility model includes: a base 1, the base 1 includes a bottom plate 11 and a positioning plate 12, the positioning plate 12 is connected to one side of the bottom plate 11, the positioning plate 12 is provided with a baffle 16 for supporting the plate 22 to be coated, the baffle 16 is provided with an opening 15, the opening 15 and the bottom plate 11 form a space for accommodating the plate 22 to be coated, the edge of the baffle 16 is provided with a first protrusion 161, a second protrusion 162, a third protrusion 163 and a fourth protrusion 164, and the distance between the first protrusion 161 and the second protrusion 162 is less than the distance between the third protrusion 163 and the fourth protrusion 164; a coating assembly 2, the coating assembly 2 is detachably connected to the base 1, the coating assembly 2 includes a coating plate 22, and the coating plate 22 is provided with a plurality of coating holes 23 corresponding to the position of the opening 15; a scraper 3, the scraper 3 is used for coating silicon grease on the plate 22 to be coated.

[0026] A tooling for applying silicone grease to a plate material in this embodiment places the plate material to be coated 22 in the opening 15. At the same time, the plate material to be coated abuts against the baffle 16. When coating the plate material, the coating plate 22 abuts against the positioning plate 12, so that the positioning plate 12 supports the coating plate 22, increasing the support area and preventing the coating plate 22 from deforming due to the scraping of the scraper 3, thereby enabling the silicone grease to be evenly coated. At the same time, the plate material to be coated can cooperate with the bayonet between the first protrusion 161 and the second protrusion 162 and the bayonet between the third protrusion 163 and the fourth protrusion 164, thereby preventing the plate material to be coated from being placed in the wrong direction when placed in the opening 15.

[0027] The base 1 includes a bottom plate 11 and a positioning plate 12. The bottom plate 11 is integrally flat and is used to support other components. The positioning plate 12 is connected to one side of the bottom plate 11. A baffle 16 for supporting the plate 22 to be coated is provided at the middle position of the positioning plate 12. An opening 15 is provided at the middle position of the baffle 16, so that the baffle 16 is located around the opening 15. The opening 15 and the bottom plate 11 form a space for accommodating the plate to be coated. The edges where the baffle 16 intersects with the opening 15 are provided with a first protrusion 161, a second protrusion 162, a third protrusion 163 and a fourth protrusion 164. The side wall of the plate to be coated is provided with a first clamping block and a second clamping block. The first protrusion 161 and the second protrusion 162 are on the same side of the baffle 16, and the third protrusion 163 and the fourth protrusion 164 are on the same side of the baffle 16. Thus, a first clamping opening capable of being clamped with the first clamping block is formed between the first protrusion 161 and the second protrusion 162, and a second clamping opening capable of being formed with the second clamping block is formed between the third protrusion 163 and the fourth protrusion 164. The first clamping opening and the second clamping opening are integrally trapezoidal. The distance between the first protrusion 161 and the second protrusion 162 is less than the distance between the third protrusion 163 and the fourth protrusion 164, so that the width of the first clamping opening is less than the width of the second clamping opening. The first protrusion 161 and the third protrusion 163 are on the opposite sides of the baffle 16, so that the first clamping opening and the second clamping opening are arranged oppositely. The different settings of the positions and widths of the first clamping opening and the second clamping opening can prevent the plate to be coated from being placed in the wrong direction when placed into the opening 15. The first protrusion 161 and the second protrusion 162 are located at the middle position on one side of the baffle 16. On the same side of the first protrusion 161 on the baffle 16, there are also a sixth protrusion 166 and a seventh protrusion 167. The sixth protrusion 166 and the seventh protrusion 167 are located at the ends on one side of the baffle 16. The plate to be coated is also provided with a third clamping block and a fourth clamping block. A third clamping opening for clamping with the third clamping block is formed between the sixth protrusion 166 and the first protrusion 161, and a fourth clamping opening for clamping with the fourth clamping block is formed between the seventh protrusion 167 and the second protrusion 162. The first clamping opening, the third clamping opening and the fourth clamping opening are on the same side of the baffle 16, and the first clamping opening is located between the third clamping opening and the fourth clamping opening. The third protrusion 163 is located at the middle position on one side of the baffle 16, and the fourth protrusion 164 is located at the end on one side of the baffle 16. On the other end on the same side as the fourth protrusion 164, there is also an eighth protrusion 168. The plate to be coated is also provided with a fifth clamping block. A fifth clamping opening for clamping with the fifth clamping block is formed between the eighth protrusion 168 and the third protrusion 163. The second clamping opening and the fifth clamping opening are on the same side of the baffle 16.The first bayonet, the third bayonet, and the fourth bayonet are located on one side of the baffle 16 and can be clamped with the first clamping block, the third clamping block, and the fourth clamping block on the same side of the plate to be coated; the second bayonet and the fifth bayonet are located on the side of the baffle 16 opposite to the first bayonet and can be clamped with the second clamping block and the fifth clamping block arranged on the side opposite to the first clamping block on the plate to be coated, so that the clamping of the plate to be coated and the baffle 16 is more stable. The setting of three bayonets on one side and two bayonets on one side can further prevent the plate to be coated from being placed in the wrong direction when placed in the opening 15, and can also enable the staff to more clearly see the correct placing direction of the plate to be coated, improving the coating efficiency.

[0028] There is a step between the baffle 16 and the positioning plate 12, so that the side wall of the baffle 16 away from the bottom plate 11 is at a certain distance from the side wall of the positioning plate 12 away from the bottom plate 11. There is a groove at the edge of the side wall of the plate to be coated away from the coating side. The setting of the step between the baffle 16 and the positioning plate 12 enables the baffle 16 to abut against the groove, while the coating side of the plate to be coated can be on the same plane as the side of the positioning plate 12 away from the bottom plate 11, thus preventing the coating plate 22 from being deformed during the coating process due to the protrusion or depression of the plate to be coated. There is a fifth protrusion 151 at the intersection position of the positioning plate 12 and the baffle 16, and the plane where the fifth protrusion 151 is located coincides with the plane where the positioning plate 12 is located. Specifically, the edge of the fifth protrusion 151 intersecting with the opening 15 is arc-shaped, and the side of the fifth protrusion 151 away from the bottom plate 11 is on the same plane as the side of the positioning plate 12 away from the bottom plate 11, thus preventing the fifth protrusion 151 from damaging the coating plate 22.

[0029] An avoidance hole 111 is provided at the position of the bottom plate 11 corresponding to the opening 15. The avoidance hole 111 is a blind hole and corresponds to the electrical components on the plate to be coated, thus preventing the electrical components from being damaged while preventing the plate to be coated from contacting the bottom plate 11. An avoidance opening 165 is provided at the position of the baffle 16 corresponding to the avoidance hole 111, so that the plate to be coated can be placed in the opening 15 without damaging the electrical components.

[0030] The positioning plate 12 is further provided with a first workpiece taking port 17 which penetrates through the positioning plate 12. At a position corresponding to the first workpiece taking port 17 on the bottom plate 11, there is a second workpiece taking port which penetrates through the bottom plate 11, and the first workpiece taking port 17 and the second workpiece taking port have the same size. The first workpiece taking port 17 and the second workpiece taking port are communicated with the opening 15. At the same time, the first workpiece taking port 17 and the second workpiece taking port are located on one side of the baffle 16 perpendicular to the side where the first protrusion 161 is located. The arrangement of the first workpiece taking port 17 and the second workpiece taking port enables the operator to conveniently place the to-be-coated plate in the opening 15, and also enables the operator to conveniently take out the to-be-coated plate from the opening 15, and the to-be-coated plate can be taken out without damaging the coating layer. Preferably, the positioning plate 12 is further provided with a third workpiece taking port 18 which is close to the edge of the opening 15 and is located on the baffle 16. The third workpiece taking port 18 penetrates through the baffle 16 and the positioning plate 12. At a position corresponding to the third workpiece taking port 18 on the bottom plate 11, there is a fourth workpiece taking port having the same size as the third workpiece taking port 18 which penetrates through the bottom plate 11. The third workpiece taking port 18 and the fourth workpiece taking port are located on the opposite side of the first workpiece taking port 17 and the second workpiece taking port. The arrangement of the third workpiece taking port 18 and the fourth workpiece taking port enables the operator to place the to-be-coated plate in the opening 15 with both hands and also enables the operator to take out the to-be-coated plate from the opening 15 with both hands, thereby improving the convenience of plate coating.

[0031] Preferably, one side of the bottom plate 11 is connected with a plurality of positioning plates 12, and the planes where the plurality of positioning plates 12 are located coincide, that is, the heights of the plurality of positioning plates 12 are the same, so that the tool for silicon grease coating of the plate can place a plurality of to-be-coated plates, improving the coating efficiency. Preferably, a first handle 14 is provided on the bottom plate 11 on the same side as the mounting plate. The first handle 14 is integrally arc-shaped, and the first handle 14 is located at the edge of the bottom plate 11 and is oppositely arranged. The arrangement of the first handle 14 can facilitate the movement of the tool for silicon grease coating of the plate. Preferably, support blocks 13 are provided at the four corner positions on the side of the bottom plate 11 away from the positioning plate 12. The support blocks 13 are made of anti-slip materials and are used to support the bottom plate 11.

[0032] Referring to Figure 4 and Figure 5 As shown, the coating assembly 2 includes a coating plate 22. The coating assembly 2 is detachably connected to the base 1. A plurality of coating holes 23 corresponding to the positions of the openings 15 are provided on the coating plate 22. Specifically, the coating holes 23 are rectangular, and the coating holes 23 are arranged at equal intervals and are provided with multiple rows at equal intervals, thereby forming a coating net. The overall size of the coating net is the same as the coating surface size of the to-be-coated plate. Preferably, a baffle 24 is provided between some adjacent coating holes 23. The baffle 24 corresponds to the position of the mounting hole on the to-be-coated plate. The baffle 24 is circular and is provided with a plurality of them. The baffle 24 can prevent the silicon grease from entering the mounting hole.

[0033] An installation frame 21 is provided at the edge of the coating plate 22, and the installation frame 21 is arranged along the perimeter of the coating plate 22. On the side of the installation frame 21 away from the base 1, there are oppositely arranged second handles 25. The connection line between the second handles 25 is perpendicular to the connection line between the first handles 14. The arrangement of the second handles 25 facilitates the movement of the installation frame 21. The inner diameter of the installation frame 21 matches the size of the positioning plate 12, enabling the installation frame 21 to be snap-fitted with the outer wall of the positioning plate 12, thereby making the coating assembly 2 detachably connected to the base 1. When the coating assembly 2 is moved to the base 1, through the snap-fitting of the installation frame 21 and the positioning plate 12, the plate to be coated within the opening 15 can be quickly aligned with the coating mesh, and the stability of the coating assembly 2 can also be maintained. In another embodiment, at least two first positioning holes are provided on the installation frame 21, and second positioning holes corresponding to the positions of the first positioning holes are provided on the bottom plate 11. After the coating assembly 2 is moved to the base 1, connection and positioning are achieved by passing positioning posts through the first positioning holes and the second positioning holes, thereby making the coating assembly 2 detachably connected to the base 1.

[0034] Referring to Figure 6 As shown, the squeegee 3 is used to apply silicone grease to the plate to be coated. The squeegee 3 is composed of a handle 31 and a blade head 34. The handle 31 and the blade head 34 are connected by a clamping plate 33. The handle 31 and the blade head 34 are clamped between the clamping plates 33, and the clamping plates 33 are connected by connecting pieces, thereby fixing the handle 31 and the blade head 34. On the opposite sides of the second handle 25 near the top, there are first adsorbing members 26. The squeegee 3 is provided with second adsorbing members 32 that can adsorb to the first adsorbing members 26. The first adsorbing members 26 and the second adsorbing members 32 can be regarded as magnets. Through the arrangement of the first adsorbing members 26 and the second adsorbing members 32, the squeegee 3 can be connected to the second handle 25, thereby facilitating the picking and placing of the squeegee 3. The squeegee 3 is connected to the opposite side of the second handle 25, and it can also prevent silicone grease from dripping outside.

[0035] During use, according to the positions of the first block, second block, third block, fourth block, and fifth block on the plate to be coated, as well as the positions of the first bayonet, second bayonet, third bayonet, fourth bayonet, and fifth bayonet on the baffle 16, place the plate to be coated into the bayonet in the correct direction; then place the coating assembly 2 on the positioning plate 12, making the installation frame 21 snap-fitted with the positioning plate 12; finally, pour silicone grease onto the coating plate 22, and apply the silicone grease to the position of the coating mesh through the squeegee 3, so that the silicone grease is applied to the coating side of the plate to be coated. After coating, connect the squeegee 3 to the second handle 25 through the first adsorbing member 26 and the second adsorbing member 32.

[0036] A tooling for silicon grease coating of a board places the board to be coated in the opening 15. Meanwhile, the board to be coated abuts against the baffle 16. When coating the board, the coating plate 22 abuts against the positioning plate 12, so that the positioning plate 12 supports the coating plate 22, increasing the support area and preventing the coating plate 22 from deforming due to the scraping of the scraper 3, thus making the silicon grease coating uniform. At the same time, the board to be coated can cooperate with the first bayonet between the first protrusion 161 and the second protrusion 162 and the second bayonet between the third protrusion 163 and the fourth protrusion 164, preventing the board to be coated from being placed in the wrong direction when placed in the opening 15. Through the clamping connection between the mounting frame 21 and the positioning plate 12, the board to be coated in the opening 15 can be quickly aligned with the coating mesh and the stability of the coating assembly 2 can be maintained. Through the setting of the step between the baffle 16 and the positioning plate 12, it is prevented that the coating plate 22 deforms during the coating process due to the protrusion or depression of the board to be coated.

[0037] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
