DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The automatic screw driving device provided by the embodiment of the present invention includes a fixture, such as Figure 2 As shown, a cavity 11 is provided in the cover plate 1 of the fixture and is connected to the screw hole 12 of the cover plate 1;

[0033] The automated screw driving equipment further includes a purge module;

[0034] like Figures 3 to 5 As shown, the purging module is used to purge the screw hole 12 after the screw 6 is fastened, so as to collect the debris 5 accumulated in the screw hole 12 into the cavity 11 .

[0035] It should be noted that if Figure 1 As shown, the screw hole 12 of the cover plate 1 is also the screw hole of the cover plate 1; the cavity 11 in the cover plate 1 connected to the screw hole 12 is used as a debris collection chamber, which is used to collect debris 5 (such as Figure 2As shown, debris 5 accumulates at the bottom of the screw hole 12); the purge end of the purge module is used to dock with the upper end of the screw hole 12 after the screw 6 is locked, so that a closed purge space is formed in the screw hole 12, which facilitates the debris 5 to be blown into the cavity 11, that is, the debris 5 accumulated in the screw hole 12 is collected in the cavity 11. In this way, when the cover 1 is lifted to prepare to remove the product, the debris in the screw hole 12 can be prevented from being scattered into the environment, thereby ensuring the cleanliness of the product and the environment. In addition, the thickness of the cavity 11 is of course less than the thickness of the cover 1, and is not less than 20mm, and the minimum distance between two adjacent screw holes 12 on the cover 1 is greater than 30mm.

[0036] That is to say, this solution adds a cavity 11 connected to the screw hole 12 in the cover plate 1, and uses a purge module to purge the screw hole 12 after the screw 6 is locked, so that the debris 5 accumulated in the screw hole 12 is blown into the cavity 11, that is, the debris 5 accumulated in the screw hole 12 is collected into the cavity 11, so that in the process of opening the cover plate 1 to take out the product 7, the debris 5 can be effectively prevented from being scattered into the production environment, thereby ensuring the cleanliness of the product and the production environment.

[0037] In this program, if Figure 2 As shown, the cavity 11 is connected to the first part 121 of the screw hole 12, and the angle formed between the cavity 11 and the first part 121 of the screw hole 12 is an acute angle, and the cavity 11 is inclined toward the second part 122 close to the screw hole 12; wherein, the first part 121 of the screw hole 12 is higher than the second part 122. The cavity 11 is not horizontally distributed, and the angle formed between the cavity 11 and the first part 121 of the screw hole 12 is an acute angle, and the cavity 11 is inclined toward the second part 122 close to the screw hole 12, which also makes the cavity 11 tilt downward, that is, the bottom of the cavity 11 is close to the inner end face 124 of the screw hole 12. In this way, not only can the debris 5 be blown into the cavity 11 under the action of blowing, but also in the process of opening the cover 1 to take out the product 7, the debris 5 collected in the cavity 11 is not easy to overflow or fall out of the cavity 11, thereby reducing the impact of the debris 5 on the product 7 and the cleanliness of the environment. In addition, as Figure 2 As shown, the first portion 121 of the screw hole 12 can be the upper middle portion of the screw hole 12, and the second portion 122 of the screw hole 12 can be the lower middle portion of the screw hole 12. Of course, the cavity 11 can also adopt other layouts, such as a curved cavity, which can include a horizontal section and a curved section, with one end of the horizontal section vertically connected to the screw hole 12 and the other end connected to the curved section, and the curved section is inclined downward.

[0038] Specifically, the angle formed between the cavity 11 and the first portion 121 of the screw hole 12 is equal to or less than 60°. This facilitates the blowing of debris 5 into the cavity 11 and prevents debris 5 from overflowing or falling out of the cavity 11 during the process of opening the cover 1 to remove the product 7. Preferably, the angle formed between the cavity 11 and the first portion 121 of the screw hole 12 is 60°.

[0039] Furthermore, if Figure 2 As shown, the cavity 11 includes at least two sub-cavities, which are symmetrically distributed about the screw hole 12. The number of sub-cavities can be an even number greater than two, and they can be divided into two groups. The two groups of sub-cavities are symmetrically distributed about the screw hole 12. This not only helps to increase the capacity of the cavity 11 to collect debris 5, but also makes it easier for the debris 5 to be blown into the cavity 11.

[0040] Furthermore, the cavity 11 can also be an annular cavity surrounding the screw hole 12. That is to say, the cavity 11 added to the cover plate 1 can also be an annular collection cavity surrounding the screw hole 12 and forming a certain acute angle with the screw hole 12. This not only makes it easier for the debris 5 to be blown into the cavity 11, but also helps to greatly improve the capacity of the cavity 11 to collect the debris 5. In addition, in order to facilitate the realization of the cavity 11 being provided in the cover plate 1, it can be considered to set the cover plate 1 as an upper cover plate and a lower cover plate that can be assembled together. The upper cover plate is provided with a through upper screw hole and an upper cavity is opened at its bottom; the lower cover plate is provided with a through lower screw hole and a lower cavity is opened at its top. After the upper cover plate and the lower cover plate are assembled together, the upper screw hole and the lower screw hole can be aligned to form the screw hole 12, and the upper cavity and the lower cavity can be aligned to form the cavity 11.

[0041] In this solution, in order to clean the debris 5 accumulated in each screw hole 12 of the cover plate 1, the number of the cavities 11 described above is multiple, and they are connected to the multiple screw holes 12 of the cover plate 1 one by one.

[0042] Specifically, if Figure 3 As shown, the purge module includes an ion wind purge module 2. This allows the rotating ion wind to lift and sweep debris 5 into the cavity 11, and can also prevent static electricity during the purge process. In addition, the ion wind purge module 2 also has a suction function, that is, it is an ion wind blowing and suction module. After the purge, if there is still debris 5 in the screw hole 12, the ion wind blowing and suction module can be used to suck the remaining debris 5 into the ion wind blowing and suction module, thereby removing the debris 5 accumulated in the screw hole 12 to the greatest extent possible.

[0043] Among them, such as Figure 3 As shown, the ion wind blowing module 2 includes: an ion wind blowing body 21 and a first cover 22;

[0044] The first cover 22 is provided at the end of the purging pipe of the ion wind purging body 21 and is used to cover the outer end surface 123 of the screw hole 12 of the cover plate 1. The first cover 22 can be pressed on the outer end surface 123 of the screw hole 12 by a mechanical arm, as shown in FIG. Figure 3 As shown, the product 7, the screw hole 12 and the first cover 22 are in close contact and form a closed space, so that it is easier for the ion wind blowing module 2 to blow the screw hole 12. Of course, the ion wind blowing body 21 has a blowing function and a suction function.

[0045] Furthermore, the automated screw driving device provided by the embodiment of the present utility model further includes a blocking member;

[0046] like Figure 6 As shown, the blocking member is used to block the inner end surface 124 of the screw hole 12 of the cover plate 1 after the cover plate 1 is inverted; the outer end surface 123 of the screw hole 12 of the cover plate 1 is also used to connect with the dust suction pipe of the vacuum cleaner 3. Among them, the inner end surface 124 of the screw hole 12 is the inner end surface (lower end surface) of the screw hole 12 when the cover plate 1 is in the closed state (horizontal state), and the outer end surface 123 of the screw hole 12 is the outer end surface (upper end surface) of the screw hole 12 when the cover plate 1 is in the closed state (horizontal state); the blocking member is used to block the inner end surface 124 (as shown in FIG. 1 ) of the screw hole 12 after the cover plate 1 is inverted. Figure 6 The upper end surface of the screw hole 12 is sealed so that the end surface of one side of the screw hole 12 is blocked, so that the suction pipe of the vacuum cleaner 3 can absorb the debris 5 from the other end surface of the screw hole 12. Figure 7 As shown, the debris 5 in the cover plate 1 is sucked into the vacuum cleaner 3, thereby ensuring the cleaning of the debris 5 in the cover plate 1; of course, the cover plate 1 is inverted after the work order is completed, and the downward tilt of the cavity 11 is changed to an upward tilt after inversion, so that the debris 5 can be gathered at the outer end of the screw hole 12, thereby making it easier for the vacuum cleaner 3 to suck and clean. In addition, as Figure 6 As shown, the vacuum cleaner 3 includes: a vacuum cleaner body 31 and a second cover body 32 ; wherein the second cover body 32 is arranged at the end of the vacuum tube of the vacuum cleaner body 31 and is used to cover the outer end surface 123 of the screw hole 12 .

[0047] Furthermore, if Figure 6 As shown, the blocking member includes a baffle 4 that is removably mounted on the inner end surface 124 of the screw hole 12. When the cover 1 is inverted, the baffle 4 can be placed directly on the inner end surface 124 of the screw hole 12, resulting in a simple and convenient blocking structure. Of course, this solution can also employ other blocking members, such as hole plugs, which will not be discussed further here.

[0048] That is, the automated screw driving equipment provided by the embodiment of the present invention adds a micro-cavity structure (i.e., cavity 11) at the screw hole position of the fixture cover, and uses an ion wind purge module with a cover above the screw hole. The specific debris cleaning process is as follows:

[0049] ①After the screws are fastened, Figure 3 As shown, the robot arm descends to press the cover connected to the fan (i.e., the ion wind blowing module) onto the upper end of the screw hole of the fixture cover, so that the product shell, cover, and cover are in close contact to form a closed space;

[0050] ② If Figure 3 and Figure 4 As shown, the fan is started to sweep the debris with rotating wind and collect the debris into the micro-cavity structure in the cover plate;

[0051] ③ Similarly, the debris is blown away in the order of screw locking and collected into the corresponding micro-cavity structure;

[0052] ④After the work order is completed, first take the fixture to the specified area and turn it upside down, such as Figure 6 As shown in the figure, a baffle is used to block one side (upper side) of the screw hole, and then the cover of the vacuum cleaner equipped on the production line is used to block the other side (lower side) of the screw hole to vacuum the debris in the micro-cavity structure, thereby cleaning the debris in the fixture. Figure 7 shown.

[0053] The overall debris cleaning effect of this automated screw driving equipment is good, with no obvious debris accumulation on the product and fixture. The cleanliness test results of the product and fixture (debris composition, weight, and size) all meet the customer's requirements for product cleanliness.
