Description

Technical Field

[0001] The present invention relates to the technical field of the production and processing of wearable watch bottom cases, and specifically relates to an automated intelligent sandblasting device for wearable watch bottom cases. Background Art

[0002] Wearable watches, usually referring to smart watches or health watches, not only have functions such as heart rate, blood oxygen, and sleep quality monitoring, but also can be connected to devices such as mobile phones through Bluetooth or Wi-Fi to achieve information synchronization and interaction. The wearable watch bottom case is an important part of the smart watch, and its functions include fixing the movement, protecting the internal parts of the watch, dustproof and waterproof, etc. During the production and processing of the wearable watch bottom case, defects such as oxide layers, dirt, and scratches are likely to occur on the surface of its parts, so it is necessary to perform a sandblasting process to remove defects such as oxide layers, dirt, and scratches on the surface of the parts, and improve the surface quality and aesthetics of the parts.

[0003] In the prior art, the traditional sandblasting treatment method requires manual operation with a sandblasting gun. When manually holding the sandblasting gun for a long time for sandblasting treatment, not only is the worker prone to fatigue, but also the long-term operation makes the labor intensity of the worker large and prone to occupational diseases. Moreover, when the worker is in a fatigued state for sandblasting treatment, not only is it easy to cause defects in the sandblasting treatment of the wearable watch bottom case, but also the sandblasting treatment efficiency will gradually decrease, resulting in low production and processing efficiency and low yield of the wearable watch bottom case.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When the circular plate rotates, the rotation of the circular plate drives a group of circular rods to rotate. Since the inner side wall of the sandblasting shell is fixedly connected with a first annular rack and the outer side walls of a group of circular rods are all fixedly connected with first gears, and a group of first gears are all meshed with the first annular rack, when the circular rods rotate, they will drive the first gears to move on the inner side wall of the first annular rack, and the first gears will rotate on their own when moving, thereby driving the circular rods to rotate on their own. The circular rods drive the placement plate, the clamping plate and the bottom shell of the wearable watch to rotate. When the sandblasting gun sandblasts the bottom shell of the wearable watch, the rotation of the bottom shell of the wearable watch changes the angle and position of sandblasting, so that the sandblasting gun can sandblast the bottom shell of the wearable watch without dead angles, and further improves the sandblasting efficiency and effect of the device when sandblasting the bottom shell of the wearable watch.

[0017] 2. When the circular rod rotates on its own and drives the placement plate to rotate, the rotation of the placement plate will cause the connecting rod hinged at the bottom of the placement plate to slide on the top end of the outer wall of the inclined block, making the connecting rod sometimes high and sometimes low, driving the placement plate to rock left and right, and the placement plate drives the clamping plate and the bottom shell of the wearable watch to rock and change positions. Therefore, when the sandblasting gun sandblasts the bottom shell of the wearable watch, through the rotation, left and right rocking and tilting of the bottom shell of the wearable watch, the bottom shell of the wearable watch can be sandblasted in multiple directions and at multiple angles, thereby improving the sandblasting quality of the bottom shell of the wearable watch.

Detailed implementation manners

[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention. Embodiment 1

[0029] Please refer to Figure 1 - Figure 7As shown in the figure, an automatic intelligent sandblasting device for the bottom shell of a wearable watch includes a base 1; a motor 2 is fixedly connected to the top end of the outer wall of the base 1; a rotating shaft 3 is provided at the output end of the motor 2; a circular plate 4 is fixedly connected to the top end of the outer wall of the rotating shaft 3; a set of circular rods 5 is arranged at the top end of the outer wall of the circular plate 4; a connecting frame 6 is fixedly connected to the top end of the outer wall of the circular rod 5; a placement plate 8 is provided on the inner side wall of the connecting frame 6 through a first rotating rod 7; a clamping member is provided at the top end of the outer wall of the placement plate 8; the clamping member includes a clamping plate 9; a sandblasting shell 10 is fixedly connected to the top end of the outer wall of the base 1 through a support column, and the sandblasting shell 10 is semicircular in shape and matches the circular plate 4; a sandblasting space is formed between the sandblasting shell 10 and the circular plate 4; a set of sandblasting guns 11 is provided on the outer side wall of the sandblasting shell 10, and the output end of the sandblasting gun 11 is located in the sandblasting space. By fixing the bottom shell of the wearable watch with the clamping member, at this time, the motor 2 drives the rotating shaft 3 and the circular plate 4 to rotate, so that the circular plate 4 drives the circular rod 5, the connecting frame 6, the placement plate 8, and the clamping member to rotate, thereby driving the bottom shell of the wearable watch to rotate, moving the bottom shell of the wearable watch into the sandblasting shell 10. At this time, the sandblasting gun 11 performs sandblasting on the bottom shell of the wearable watch. And due to the different angles and positions of a set of sandblasting guns 11, and the rotation of the bottom shell of the wearable watch as the circular plate 4 rotates, when the bottom shell of the wearable watch is rotated for sandblasting, it can be sandblasted from multiple angles, reducing the defect rate when the bottom shell of the wearable watch is sandblasted, making the sandblasting of the bottom shell of the wearable watch better. And because this device is fully automatic sandblasting, the yield rate and sandblasting efficiency are kept stable and not easily reduced, making the processing efficiency and yield rate of this device relatively high when processing and manufacturing the bottom shell of the wearable watch.

[0030] A vertical plate 12 is fixedly connected to the top end of the outer wall of the placement plate 8; a bidirectional threaded rod 13 is rotatably connected to one side of the outer wall of the vertical plate 12; a pair of clamping plates 9 are both threadedly connected to the bidirectional threaded rod 13, and the bottom ends of the outer walls of the pair of clamping plates 9 are both slidably connected to the top end of the outer wall of the placement plate 8; the opposite sides of the outer walls of the pair of clamping plates 9 are both arc-shaped. By rotating the bidirectional threaded rod 13, since the pair of clamping plates 9 are both threadedly connected to the bidirectional threaded rod 13, the rotation of the bidirectional threaded rod 13 drives the pair of clamping plates 9 to move, moving the pair of clamping plates 9 to a suitable position. At this time, place the bottom shell of the wearable watch between the pair of clamping plates 9, and then rotate the bidirectional threaded rod 13 to clamp and fix the bottom shell of the wearable watch with the pair of clamping plates 9. And due to the shape of the clamping plate 9, when the bottom shell of the wearable watch is placed, it has support at the bottom and is fixed on both sides, making the bottom shell of the wearable watch more stable during sandblasting, so that the bottom shell of the wearable watch is not easily moved or shaken during sandblasting, thereby reducing the defect rate and error rate during sandblasting.

[0031] The inner side wall of the sandblasting shell 10 is fixedly connected with a first annular rack 14; the bottom ends of the outer walls of a group of circular rods 5 are all rotatably connected to the top end of the outer wall of the circular plate 4; the outer side walls of a group of circular rods 5 are all fixedly connected with first gears 15, and a group of first gears 15 are all meshed with the first annular rack 14. When the circular plate 4 rotates, the rotation of the circular plate 4 drives a group of circular rods 5 to rotate. Since the inner side wall of the sandblasting shell 10 is fixedly connected with the first annular rack 14 and the outer side walls of a group of circular rods 5 are all fixedly connected with first gears 15, and a group of first gears 15 are all meshed with the first annular rack 14, when the circular rods 5 rotate, it will drive the first gears 15 to move on the inner side wall of the first annular rack 14, and when the first gears 15 move, they will rotate on their own axes, thereby driving the circular rods 5 to rotate on their own axes, so that the circular rods 5 drive the placing plate 8, the clamping plate 9 and the bottom shell of the wearable watch to rotate. When the sandblasting gun 11 sandblasts the bottom shell of the wearable watch, the rotation of the bottom shell of the wearable watch changes the angle and position of the sandblasting, so that the sandblasting gun 11 can sandblast the bottom shell of the wearable watch without dead angles, and further improves the sandblasting efficiency and effect when the device sandblasts the bottom shell of the wearable watch.

[0032] A set of second reciprocating rods 23 are rotatably connected to the top end of the outer wall of the first annular rack 14, and the set of second reciprocating rods 23 are all located inside the sandblasting shell 10; a second annular rack 24 is provided on the outer side wall of the set of circular rods 5, and the second annular rack 24 is rotatably connected to the set of circular rods 5; a third gear 25 is fixedly connected to the outer side wall of the second reciprocating rod 23, and the third gear 25 meshes with the second annular rack 24; a sliding plate 26 is arranged on the outer side wall of the second reciprocating rod 23, and one side of the outer wall of the sliding plate 26 is in contact with the inner side wall of the sandblasting shell 10; an adjusting plate 27 is provided on one side of the outer wall of the sliding plate 26; a set of first through grooves 28 are formed in the outer side wall of the sandblasting shell 10; a set of baffles 29 are slidably connected to the outer side wall of the sandblasting shell 10, and the set of baffles 29 respectively match the set of first through grooves 28; a set of sandblasting guns 11 are respectively arranged on one side of the outer wall of the set of baffles 29, and one end of the outer wall of the output end of the sandblasting gun 11 penetrates through the baffle 29 and the adjusting plate 27; the set of sandblasting guns 11 are respectively fixedly connected to the set of adjusting plates 27; the output ends of the set of sandblasting guns 11 are respectively located in the set of first through grooves 28. When the circular plate 4 drives the set of circular rods 5 to rotate, the set of circular rods 5 will drive the second annular rack 24 to rotate. Since the third gear 25 meshes with the second annular rack 24, when the second annular rack 24 rotates, it will drive the third gear 25 to rotate, so that the third gear 25 drives the second reciprocating rod 23 to rotate, and the rotation of the second reciprocating rod 23 drives the sliding plate 26 to reciprocate up and down. Thus, the sliding plate 26 drives the sandblasting gun 11 to move up and down through the adjusting plate 27, and the sandblasting gun 11 moves in the first through groove 28. Therefore, when sandblasting the bottom shell of the wearable watch, its body will not only rotate and shake, but also the height of the sandblasting gun 11 will change, so that the sandblasting effect of the device is better. And because the set of baffles 29 respectively match the set of first through grooves 28, when sandblasting the bottom shell of the wearable watch in the sandblasting shell 10, the sand is not easily removed from the sandblasting shell 10, thus protecting the environmental safety.

[0033] Both ends of the outer wall of the first rotating rod 7 are fixedly connected to the opposite inner sides of the inner wall of the connecting frame 6; the first rotating rod 7 is rotatably connected to the placing plate 8; the top end of the outer wall of the circular plate 4 is fixedly connected with a group of inclined blocks 16 through a group of first round rods, and the cross section of the inclined blocks 16 is annular; a group of inclined blocks 16 are respectively sleeved outside a group of circular rods 5, and a group of inclined blocks 16 are respectively matched with a group of placing plates 8; the bottom end of the outer wall of the placing plate 8 is hinged with a connecting rod 17, and the bottom end of the outer wall of the connecting rod 17 is slidably connected to the top end of the outer wall of the inclined block 16. When the circular rod 5 rotates itself to drive the placing plate 8 to rotate, the rotation of the placing plate 8 will cause the connecting rod 17 hinged to the bottom of the placing plate 8 to slide on the top end of the outer wall of the inclined block 16, so that the connecting rod 17 will be high and low, driving the placing plate 8 to rock left and right, causing the placing plate 8 to drive the clamping plate 9 and the bottom shell of the wearable watch to rock and change positions. Thus, when the sandblasting gun 11 sandblasts the bottom shell of the wearable watch, through the rotation, left and right rocking and inclination of the bottom shell of the wearable watch, the bottom shell of the wearable watch can be sandblasted in multiple directions and at multiple angles, thereby improving the sandblasting quality of the bottom shell of the wearable watch.

[0034] The center of the top end of the outer wall of the cleaning block 19 is rotatably connected with a rotating rod 30, and the bottom end of the outer wall of the rotating rod 30 penetrates through the cleaning block 19; one end of the rotating rod 30 penetrating through the outer wall of the cleaning block 19 is fixedly connected with a group of auxiliary plates 31; the outer side wall of the end of the rotating rod 30 that does not penetrate through the cleaning block 19 is fixedly connected with a fifth gear 32; the top end of the outer wall of the placing plate 8 is fixedly connected with a fifth rack 33 through a second square plate, and the fifth rack 33 meshes with the fifth gear 32. When the cleaning block 19 reciprocates, the cleaning block 19 will drive the rotating rod 30 and the fifth gear 32 on the rotating rod 30 to move. Because the fifth rack 33 meshes with the fifth gear 32 and the fifth rack 33 maintains a precise state, when the fifth gear 32 moves on the fifth gear 32, it will rotate itself, thereby driving the rotating rod 30 to rotate itself, causing the rotating rod 30 to drive a group of auxiliary plates 31 to rotate, so that a group of auxiliary plates 31 clean the outer surface of the bottom shell of the wearable watch, further improving the efficiency and effect when the device cleans the bottom shell of the wearable watch, and also increasing the cleaning range.

[0035] The rotating rod 30 includes a circular shell 301 and an adjusting rod 302; the outer wall of the adjusting rod 302 is slidably connected to the inner wall of the circular shell 301; one end of the outer wall of a group of auxiliary plates 31 is fixedly connected to the outer wall of the adjusting rod 302; the top end of the outer wall of the adjusting rod 302 is rotatably connected to a first threaded rod 34, and the top end of the outer wall of the first threaded rod 34 penetrates through the circular shell 301; the first threaded rod 34 is threadedly connected to the circular shell 301. By the rotating rod 30 including the circular shell 301 and the adjusting rod 302, when the first threaded rod 34 rotates, since the first threaded rod 34 is threadedly connected to the circular shell 301, the rotation of the first threaded rod 34 causes the first threaded rod 34 to move up and down, so that the first threaded rod 34 drives the adjusting rod 302 to move up and down in the circular shell 301, thereby driving a group of auxiliary plates 31 to move up and down. Thus, the position of the auxiliary plate 31 can be adjusted by rotating the first threaded rod 34, so that the auxiliary plate 31 can adjust its height according to the specific situation of the bottom shell of the wearable watch, and the position of the auxiliary plate 31 can be adjusted according to whether the outer surface dust of the bottom shell of the wearable watch needs to be cleaned, or the excess sandblasting needs to be cleaned, or the situation of the bottom shell of the wearable watch after sandblasting. Therefore, the device is more flexible, convenient and practical.

[0036] One side of the outer wall of the vertical plate 12 is rotatably connected to a first reciprocating rotating rod 18, and one end of the outer wall of the first reciprocating rotating rod 18 penetrates through the vertical plate 12; a cleaning block 19 is arranged on the outer wall of the first reciprocating rotating rod 18; one side of the outer wall of the vertical plate 12 is fixedly connected to a guiding rod 20, and one end of the outer wall of the guiding rod 20 penetrates through the cleaning block 19; the guiding rod 20 is slidably connected to the cleaning block 19; one end of the outer wall of the first reciprocating rotating rod 18 is fixedly connected to a second gear 21; one side of the outer wall of the connecting frame 6 is fixedly connected to an arc-shaped rack 22 through a connecting block; the arc-shaped rack 22 meshes with the second gear 21. When the placing plate 8 sways and tilts left and right, the placing plate 8 will drive the first reciprocating rotating rod 18 and the second gear 21 to sway left and right through the vertical plate 12. Since the arc-shaped rack 22 meshes with the second gear 21 and the arc-shaped rack 22 remains fixed, when the second gear 21 sways left and right, it will move on the arc-shaped rack 22, and when the second gear 21 moves, it will rotate itself, thereby driving the first reciprocating rotating rod 18 to rotate. The rotation of the first reciprocating rotating rod 18 drives the cleaning block 19 to move. When the sandblasting gun 11 sandblasts the bottom shell of the wearable watch, the movement of the cleaning block 19 can clean the excess sandblasting accumulated on the bottom shell of the wearable watch, so that when the bottom shell of the wearable watch is sandblasted, it is not easy to cause too much sandblasting to accumulate on its outer surface, which will make the subsequent grinding more time-consuming. Therefore, the device can not only make the bottom shell of the wearable watch sandblast better, but also prevent too much sandblasting from accumulating on the bottom shell of the wearable watch, saving the time required for subsequent processing and improving the overall production and processing efficiency of the bottom shell of the wearable watch. Embodiment 2

[0037] Please refer to Figure 7 -Figure 8 As shown, one side of the outer wall of the adjusting plate 27 is slidably connected to one side of the outer wall of the sliding plate 26; a fixed block 35 is fixedly connected to one side of the outer wall of the adjusting plate 27; the top end of the outer wall of the fixed block 35 is rotatably connected to a second threaded rod 36, and the top end of the outer wall of the second threaded rod 36 penetrates through the sliding plate 26; the second threaded rod 36 is threadedly connected to the sliding plate 26; the sandblasting gun 11 is matched with the placing plate 8. By rotating the second threaded rod 36, since the second threaded rod 36 is threadedly connected to the sliding plate 26, when the second threaded rod 36 rotates, the second threaded rod 36 will move up and down, thereby driving the fixed block 35, the adjusting plate 27 and the sandblasting gun 11 to adjust their positions. Thus, the moving range of the sandblasting gun 11 can be adjusted by rotating the second threaded rod 36 of the present device, so that more situations can be dealt with. Also, the present device can adjust the moving range of the sandblasting gun 11 according to the sandblasting situation and the situation of the bottom case of the wearable watch, so that the bottom case of the wearable watch can be better sandblasted.

[0038] When the present invention is in use, by rotating the bidirectional threaded rod 13, since a pair of clamping plates 9 are both threadedly connected to the bidirectional threaded rod 13, the rotation of the bidirectional threaded rod 13 drives the movement of a pair of clamping plates 9, so that a pair of clamping plates 9 move to a suitable position. At this time, the bottom shell of the wearable watch is placed between a pair of clamping plates 9, and then the bidirectional threaded rod 13 is rotated, so that a pair of clamping plates 9 clamp and fix the bottom shell of the wearable watch. And due to the shape of the clamping plate 9, when the bottom shell of the wearable watch is placed, it has support at the bottom and is fixed on both sides, so that the bottom shell of the wearable watch is more stable during sandblasting. At this time, the motor 2 drives the rotating shaft 3 and the circular plate 4 to rotate, so that the circular plate 4 drives the circular rod 5, the connecting frame 6, the placing plate 8, and the clamping member to rotate, thereby driving the bottom shell of the wearable watch to rotate, and moving the bottom shell of the wearable watch into the sandblasting shell 10. At this time, the sandblasting gun 11 performs sandblasting on the bottom shell of the wearable watch. And due to the different angles and positions of a group of sandblasting guns 11, and the rotation of the bottom shell of the wearable watch as the circular plate 4 rotates, when the bottom shell of the wearable watch rotates for sandblasting, it can be sandblasted from multiple angles, reducing the defect rate when sandblasting the bottom shell of the wearable watch, making the sandblasting of the bottom shell of the wearable watch better. And because this device is a full-automatic sandblasting device, the yield rate and sandblasting efficiency are kept stable and are not easily reduced, so that the processing efficiency and yield rate of this device are both high when producing and processing the bottom shell of the wearable watch. And when the circular plate 4 rotates, the rotation of the circular plate 4 drives a group of circular rods 5 to rotate. Since the inner side wall of the sandblasting shell 10 is fixedly connected with a first annular rack 14 and the outer side walls of a group of circular rods 5 are all fixedly connected with first gears 15, and a group of first gears 15 are all engaged with the first annular rack 14, when the circular rod 5 rotates, it will drive the first gear 15 to move on the inner side wall of the first annular rack 14, and the first gear 15 will rotate automatically when moving, thereby driving the circular rod 5 to rotate automatically, so that the circular rod 5 drives the placing plate 8, the clamping plate 9, and the bottom shell of the wearable watch to rotate. When the sandblasting gun 11 performs sandblasting on the bottom shell of the wearable watch, the rotation of the bottom shell of the wearable watch changes the angle and position of sandblasting, so that the sandblasting gun 11 can sandblast the bottom shell of the wearable watch without dead angles. And when the circular rod 5 rotates automatically and drives the placing plate 8 to rotate, the rotation of the placing plate 8 will cause the connecting rod 17 hinged to the bottom of the placing plate 8 to slide on the top end of the outer wall of the inclined block 16, so that the connecting rod 17 will be high and low, driving the placing plate 8 to rock left and right, so that the placing plate 8 drives the clamping plate 9 and the bottom shell of the wearable watch to rock and change positions. Thus, when the sandblasting gun 11 performs sandblasting on the bottom shell of the wearable watch, through the rotation, left and right rocking, and tilting of the bottom shell of the wearable watch, the bottom shell of the wearable watch can be sandblasted in multiple directions and from multiple angles, thereby improving the sandblasting quality of the bottom shell of the wearable watch. And when the placing plate 8 rocks left and right and tilts, the placing plate 8 will drive the first reciprocating rotating rod 18 and the second gear 21 to rock left and right through the vertical plate 12. Since the arc-shaped rack 22 is engaged with the second gear 21 and the arc-shaped rack 22 remains fixed, when the second gear 21 rocks left and right, it will move on the arc-shaped rack 22, and the second gear 21 will rotate automatically when moving,Thereby driving the first reciprocating rotating rod 18 to rotate, the rotation of the first reciprocating rotating rod 18 drives the cleaning block 19 to move. When the sandblasting gun 11 performs sandblasting on the bottom shell of the wearable watch, the movement of the cleaning block 19 can clean the excess sand accumulated on the bottom shell of the wearable watch. And when the cleaning block 19 reciprocates, the cleaning block 19 will drive the rotating rod 30 and the fifth gear 32 on the rotating rod 30 to move. Since the fifth rack 33 meshes with the fifth gear 32 and the fifth rack 33 maintains a precise state, when the fifth gear 32 moves on the fifth gear 32, it will rotate itself, thereby driving the rotating rod 30 to rotate, and the rotating rod 30 drives a group of auxiliary plates 31 to rotate, so that a group of auxiliary plates 31 clean the outer surface of the bottom shell of the wearable watch, further improving the efficiency and effect when the device cleans the bottom shell of the wearable watch. And because the rotating rod 30 includes a circular shell 301 and an adjusting rod 302, when the first threaded rod 34 rotates, since the first threaded rod 34 is threadedly connected to the circular shell 301, the rotation of the first threaded rod 34 causes the first threaded rod 34 to move up and down, and the first threaded rod 34 drives the adjusting rod 302 to move up and down in the circular shell 301, thereby driving a group of auxiliary plates 31 to move up and down. Thus, the device can adjust the position of the auxiliary plate 31 by rotating the first threaded rod 34, so that the auxiliary plate 31 can adjust its height according to the specific situation of the bottom shell of the wearable watch, and can also adjust the position of the auxiliary plate 31 according to whether the outer surface dust of the bottom shell of the wearable watch needs to be cleaned, or the excess sand needs to be cleaned, or the situation of the bottom shell of the wearable watch after sandblasting. Thus, the device is more flexible, convenient and practical. And when the circular plate 4 drives a group of circular rods 5 to rotate, a group of circular rods 5 will drive the second annular rack 24 to rotate. Since the third gear 25 meshes with the second annular rack 24, when the second annular rack 24 rotates, it will drive the third gear 25 to rotate, and the third gear 25 drives the second reciprocating rotating rod 23 to rotate, and the rotation of the second reciprocating rotating rod 23 drives the sliding plate 26 to reciprocate up and down, so that the sliding plate 26 drives the sandblasting gun 11 to move up and down through the adjusting plate 27, and the sandblasting gun 11 moves in the first through groove 28. Thus, when sandblasting the bottom shell of the wearable watch, its body will not only rotate and shake, but the sandblasting gun 11 will also change its height, so that the sandblasting effect of the device is better. And by rotating the second threaded rod 36, since the second threaded rod 36 is threadedly connected to the sliding plate 26, when the second threaded rod 36 rotates, the second threaded rod 36 will move up and down, thereby driving the fixed block 35, the adjusting plate 27 and the sandblasting gun 11 to adjust their positions. Thus, the device can adjust the moving range of the sandblasting gun 11 by rotating the second threaded rod 36, so as to cope with more situations, and the device can also adjust the moving range of the sandblasting gun 11 according to the sandblasting situation and the situation of the bottom shell of the wearable watch, so that the bottom shell of the wearable watch can be better sandblasted.,
