As shown in fig. 1 and 2, the embodiment provides a watch glass opener which can be used for watch maintenance. Specifically, the watch glass opener can be used to separate the watch glass 72 from the watch case 71 in the watch 70 to be repaired, so as to facilitate the repair of a movement (not shown) or the like located in the watch case 71.
As shown in fig. 1, 2 and 5, the watch glass opener includes a frame 10, a first pneumatic driving mechanism 20, a second pneumatic driving mechanism 30, an inflating mechanism 40 and an air supplying mechanism 50.
The frame 10 can be used as a mounting carrier in a watch glass opener and can be used for carrying other mechanisms. Specifically, the first pneumatic driving mechanism 20, the second pneumatic driving mechanism 30, the inflating mechanism 40 and the air supplying mechanism 50 may be mounted on the frame 10.
The first pneumatic drive mechanism 20 is disposed opposite the second pneumatic drive mechanism 30. Therein, the first pneumatic drive mechanism 20 may be used to receive a bezel 72 in a watch 70 to be serviced. The second pneumatic drive mechanism 30 may be used to press against the watch case 71 of the watch 70 to be repaired to ensure that the watch case 71 is fixed relative to the frame 10.
The inflation mechanism 40 is used to communicate with a conduit 73 of the watch 70 to be serviced. It is understood that the conduit 73 may communicate with an internal cavity of the watch 70 to be maintained, wherein the internal cavity of the watch 70 to be maintained may refer to a cavity defined by the watch case 71 and the watch glass 72 for accommodating a movement and the like. In operation, inflation mechanism 40 may inflate the internal cavity of watch 70 to be serviced through conduit 73.
As shown in fig. 1 and 5, in the embodiment, the air supply mechanism 50 is respectively communicated with the first pneumatic drive mechanism 20, the second pneumatic drive mechanism 30 and the air charging mechanism 40. In operation, the gas supply mechanism 50 supplies gas to the first pneumatic drive mechanism 20, the second pneumatic drive mechanism 30, and the inflation mechanism 40, respectively.
When it is necessary to separate the watch case 71 and the watch glass 72 in the wristwatch 70 to be maintained, the wristwatch 70 to be maintained can be placed on the stand 10. Specifically, the watch glass 72 may be directed toward the first pneumatic drive mechanism 20, and correspondingly, the side of the watch case 71 facing away from the watch glass 72 may be directed toward the second pneumatic drive mechanism 30. At the same time, the conduit 73 in the watch 70 to be serviced is brought into communication with the inflation mechanism 40. In an embodiment, the second pneumatic driving mechanism 30 may be supplied with air from the air supply mechanism 50 so that the second pneumatic driving mechanism 30 presses and fixes the wristwatch case 71 to the rack 10 to restrain the wristwatch case 71 in the axial direction of the wristwatch 70 to be serviced. Wherein the axial direction of the watch 70 to be maintained may refer to the extending direction of the axis L.
Subsequently, the first pneumatic drive mechanism 20 and the inflation mechanism 40 can be supplied with air from the air supply mechanism 50, respectively, to cause the first pneumatic drive mechanism 20 to be linked with the inflation mechanism 40 to separate the glass 72 from the case 71. Specifically, the first pneumatic driving mechanism 20 may be abutted against the watch glass 72, the inflating mechanism 40 may inflate a certain amount of gas into the internal cavity of the watch 70 to be maintained, and the force of the watch glass 72 is balanced, that is, the watch glass 72 is kept fixed relative to the watch case 71. Then, the force applied to the watch glass 72 by the first pneumatic driving mechanism 20 can be gradually reduced, so that the force applied to the side of the watch glass 72 close to the internal cavity is gradually larger than the sum of the force applied to the side of the watch glass 72 close to the first pneumatic driving mechanism 20 and the friction between the watch glass 72 and the watch case 71. Further, the glass 72 is gradually and gently detached from the case 71, that is, the detachment between the glass 72 and the case 71 is realized. It can be understood that, during this period, the watch glass 72 is always received by the first pneumatic driving mechanism 20, and the acting force received by the watch glass 72 changes gradually, so that the problems of splashing, cracking and the like caused by the violent impact on the watch glass 72 can be avoided, and the collision damage caused by the flying-out of the structure such as the movement located in the internal cavity can also be avoided.
As shown in fig. 1 and 2, the housing 10 includes a mounting panel 11 parallel to a horizontal plane, and when the watch case 71 and the watch glass 72 are separated, the watch 70 to be repaired can be placed on the mounting panel 11. In the embodiment, the first pneumatic drive mechanism 20 is installed below the installation panel 11. The second pneumatic drive mechanism 30 is mounted above the mounting panel 11, i.e. on the side of the mounting panel 11 facing away from the first pneumatic drive mechanism 20.
When the wristwatch 70 to be maintained is placed on the mounting panel 11, the glass 72 side faces the first pneumatic drive mechanism 20, and the case 71 side facing away from the glass 72 faces the second pneumatic drive mechanism 30. The mounting panel 11 has a through hole 111 for the first pneumatic driving mechanism 20 to pass through to receive the watch glass 72. The diameter of the through hole 111 may be larger than or equal to the diameter of the watch glass 72 so that the watch glass 72 can pass smoothly, achieving separation of the watch glass 72 from the watch case 71. Meanwhile, the diameter of the through hole 111 is smaller than the outer diameter of the watchcase 71, so that the watchcase 71 can be supported by the mounting panel 11, the watchcase 71 is limited, and the watch glass 72 can be smoothly separated from the watchcase 71.
As shown in fig. 1 to 3, the first pneumatic drive mechanism 20 includes a first cylinder 21 and a first presser 22. The first cylinder 21 may be fixedly mounted on the frame 10 by screws, clamping, welding, and the like, and is located below the mounting panel 11. The first pressing block 22 can be fixedly connected to the first moving plate 23 through a screw connection, a clamping connection, a welding connection, and the like, and the first moving plate 23 can be fixedly connected to the piston rod of the first cylinder 21 through a welding connection, a screw connection, an integral forming, and the like. It can be understood that the first moving plate 23 is connected to one end of the corresponding piston rod located outside the cylinder body in the first cylinder 21, and the first pressing block 22 is located on one side of the first cylinder 21 close to the second pneumatic driving mechanism 30.
In an embodiment, the first cylinder 21 may be in communication with the air supply mechanism 50. Accordingly, the air supply mechanism 50 can supply air to the first air cylinder 21 to move the first moving plate 23 up and down with respect to the first air cylinder 21. Further, the first moving plate 23 drives the first pressing block 22 to move up and down, so that the first pressing block 22 is close to or far away from the watch 70 to be maintained. In operation, first press block 22 may be configured to receive watch glass 72.
In some embodiments, the cross-section of first compact 22 may be circular, parallel to the horizontal direction. The diameter of the first presser piece 22 may be equal to or smaller than the diameter of the through hole 111 so that the first presser piece 22 is smoothly inserted into the through hole 111 to receive the watch glass 72. Meanwhile, the diameter of first press piece 22 may be equal to or smaller than the diameter of watch glass 72, and first press piece 22 does not contact watch case 71.
In other embodiments, a side of the watch glass 72 may be provided to protrude with respect to the watch case 71, and accordingly, the diameter of the first presser piece 22 may be larger than that of the watch glass 72.
During operation, the first cylinder 21, the first moving plate 23, the first pressing block 22 and the watch 70 to be maintained can be coaxially arranged, so that the watch 70 to be maintained is uniformly stressed, and the watch 70 to be maintained is prevented from being damaged.
As shown in fig. 1 and 3, the second pneumatic driving mechanism 30 includes a second cylinder 31, a second presser 32, and a holder 33. Wherein the fixing frame 33 can be used as a mounting carrier in the second pneumatic driving mechanism 30. One end of the fixing frame 33 can be fixedly installed on one side of the installation panel 11 departing from the first pneumatic driving mechanism 20 through screw connection, welding, clamping and the like. In an embodiment, the fixing frame 33 may be perpendicular to the mounting panel 11.
The second cylinder 31 can be fixedly mounted on one end of the fixing frame 33 far away from the mounting panel 11 by means of screw connection, welding, clamping, etc. to provide a space for the second cylinder 31 to move. Meanwhile, the second cylinder 31 is opposed to the first cylinder 21. The second pressing block 32 can be fixedly connected to the second moving plate 34, and one side of the second moving plate 34 away from the second pressing block 32 can be connected to the piston rod of the second cylinder 31 through screw welding, clamping, welding and the like. Specifically, the second moving plate 34 is connected to one end of the corresponding piston rod located outside the cylinder body in the second cylinder 31. In the embodiment, the second presser 32 is located on the side of the second cylinder 31 close to the first pneumatic drive mechanism 20.
In the embodiment, the second cylinder 31 communicates with the air supply mechanism 50. In operation, the gas supply mechanism 50 can supply gas to the second cylinder 31 to drive the second cylinder 31 to operate. Specifically, the second moving plate 34 can be moved up and down relative to the cylinder body of the second cylinder 31, and then the second moving plate 34 drives the second pressing block 32 to move up and down, so that the second pressing block 32 is close to or far away from the mounting panel 11, and then the watch case 71 is pressed or released.
It will be appreciated that the second cylinder 31, the second moving plate 34 and the second presser 32 are all coaxial with the first presser 22 to ensure the balance of the forces on the watch 70 to be serviced.
As shown in fig. 2 and 4, the watch glass opener further includes two opposite positioning blocks 63, the two positioning blocks 63 may be fixedly mounted on one side of the mounting panel 11 close to the second pneumatic driving mechanism 30 by means of screw connection, welding, clamping, and the like, and the two positioning blocks 63 are symmetrically arranged with respect to the inflating mechanism 40. In use, the two positioning blocks 63 may cooperate to position one side of the watch 70 to be repaired.
Further, the watch glass opener also comprises a third cylinder 61 and a third pressing block 62. The third cylinder 61 is communicated with the gas supply mechanism 50 so that the gas can be supplied to the third cylinder 61 by the gas supply mechanism 50. The third cylinder 61 may be fixedly mounted on the mounting panel 11 at a side close to the second pneumatic driving mechanism 30 by means of screw connection, clamping, welding, and the like, and is located on the right side of the mounting panel 11. The third pressing block 62 may be fixedly connected to one side of the third moving plate 64 by means of screws, welding, and the like, and one side of the third moving plate 64 away from the third pressing block 62 may be fixedly connected to the piston rod of the third cylinder 61 by means of screws, welding, clamping, and the like. Specifically, the third moving plate 64 is connected to one end of the corresponding piston rod located outside the cylinder body in the third cylinder 61. In the embodiment, the third pressing block 62 is located on the side of the third cylinder 61 close to the positioning block 63.
In the embodiment, the third pressing block 62 and the two positioning blocks 63 are respectively disposed at two sides of the through hole 111, the third pressing block 62 is disposed opposite to the two positioning blocks 63, and the two positioning blocks 63 are symmetrical with respect to the third pressing block 62.
During operation, the third cylinder 61 can drive the third pressing block 62 to move, so that the third pressing block 62 is close to or far away from the two positioning blocks 63. Therefore, the watch 70 to be maintained can be clamped or released by the cooperation of the third pressing block 62 and the two positioning blocks 63, and particularly, the watch case 71 of the watch 70 to be maintained can be clamped or released by the cooperation of the third pressing block 62 and the two positioning blocks 63.
In some embodiments, as shown in fig. 4, the positioning blocks 63 are provided with cut faces 631 for engaging with the case 71 on the sides near the through holes 111. On one hand, the edges of the positioning blocks 63 can be prevented from scratching the side walls of the watch 70 to be maintained, and on the other hand, a larger bearing area can be provided for the watch 70 to be maintained, so as to ensure the stability of the watch case 71. One side of the third pressing block 62 close to the positioning block 63 is provided with a concave surface 621 used for attaching the watch 70 to be maintained. In particular, concave surface 621 may be a circular arc concave surface and adapted to the shape of the sidewall of case 71. Accordingly, the third pressing block 62 can be matched with the two positioning blocks 63 to provide a stable and reliable clamping function for the watch case 71.
As shown in fig. 2 and 4, further, the inflation mechanism 40 may include a sliding plate 41, a guide post 45, a flexible air nozzle 42, and an air nozzle connector 43.

In the embodiment, the guide post 45 is perpendicular to the mounting panel 11.
One end of the sliding plate 41 is slidably mounted on the guiding post 45, and the sliding plate 41 can slide up and down along the guiding post 45 to adjust the distance between the sliding plate 41 and the mounting panel 11, i.e. the sliding direction of the sliding plate 41 is parallel to the axial direction of the watch 70 to be maintained.
In the embodiment, the cross section of the guide post 45 is non-circular in the direction parallel to the mounting panel 11, and the cross section of the guide post 45 may be square, rectangular, oval, triangular, or the like. The sliding plate 41 is provided with a slide 412 adapted to the guide post 45, and the cross-sectional shape of the slide 412 is the same as the cross-sectional shape of the guide post 45 in the direction parallel to the mounting panel 11. Thus, the slide plate 41 is prevented from being rotated freely with respect to the guide post 45.
In some embodiments, a retaining ring 46 may be fixedly connected to an end of the guide post 45 away from the mounting panel 11 by a screw, so as to limit the sliding plate 41 and prevent the sliding plate 41 from being detached from the guide post 45.
As shown in fig. 2 and 4, the other end of the sliding plate 41 may be extended toward the two positioning blocks 63. Flexible air nozzle 42 may be fixedly attached to the end of slide plate 41 adjacent to positioning block 63 by air nozzle connector 43. Meanwhile, the flexible air nozzle 42 can be inserted between the two positioning blocks 63 and extend to one side of the two positioning blocks 63 close to the third pressing block 62, so that the flexible air nozzle 42 is connected with the conduit 73 in the watch 70 to be maintained.
It will be appreciated that the mounting height of the conduit 73 may vary for different models of watches 70 to be serviced. In one embodiment, the sliding plate 41 can slide up and down relative to the mounting panel 11, so that the height of the flexible air nozzle 42 relative to the mounting panel 11 can be adjusted as required, so that the height of the flexible air nozzle 42 is adapted to the height of the conduit 73, thereby ensuring smooth communication between the flexible air nozzle 42 and the conduit 73.
In an embodiment, the flexible air nozzle 42 may be made of a flexible material such as rubber, silicon, etc. When the conduit 73 is inserted into the flexible nozzle 42, the conduit 73 may be in interference fit with the flexible nozzle 42 to improve the sealing performance.
In addition, when third pressing block 62 is matched with two positioning blocks 63 to clamp watchcase 71, the end surface of flexible air tap 42 far away from one end of sliding plate 41 can be in sealed contact with the side wall of watchcase 71, so that air leakage at the connection part of flexible air tap 42 and conduit 73 can be prevented. By making the flexible air nozzle 42 of a flexible material, the sealing property at the position where the flexible air nozzle 42 abuts the exterior case 71 can also be improved.
As shown in fig. 2, a bent flow passage 411 is formed in the sliding plate 41, and one end of the bent flow passage 411 is communicated with the flexible air faucet 42. The other end of the bent flow passage 411 may communicate with the gas supply mechanism 50 through a gas pipe joint 44. Thus, the air supply mechanism 50 can supply air to the conduit 73 sequentially through the air pipe connector 44, the bent flow passage 411 and the flexible air tap 42 to inflate the internal cavity of the watch 70 to be repaired.
In an embodiment, the air pipe connector 44 may be fixedly installed on the sliding plate 41 to follow the sliding plate 41 to move up and down. A through hole opposite to the air pipe joint 44 may be opened on the installation panel 11. On one hand, the air pipe joint 44 can be provided with a containing space, and on the other hand, the connection between the air pipe joint 44 and the air supply mechanism 50 can be facilitated.
With reference to fig. 2 to 5, the air supply mechanism 50 may include an air pump 51, a four-way valve 52, and a three-way valve 53. Wherein, the air pump 51 can be used as an air source to supply air to the first cylinder 21, the second cylinder 31, the third cylinder 61 and the air charging mechanism 40.
In one embodiment, the output of the air pump 51 may be in communication with the input of the four-way valve 52 via an air line. A first output end of the four-way valve 52 and an input end of the three-way valve 53 can be communicated through a gas pipe, and a switch valve 54 can be arranged on the gas pipe between the four-way valve 52 and the three-way valve 53 to control the on-off of the gas path. A second output end of the four-way valve 52 can be connected to the second cylinder 31 through a gas pipe, and a first direction changing valve 58 is disposed on the gas pipe between the four-way valve 52 and the second cylinder 31. A third output end of the four-way valve 52 can be connected with the third cylinder 61 through a gas pipe, and a second reversing valve 59 is arranged on the gas pipe between the four-way valve 52 and the third cylinder 61.
In an embodiment, the first output port of the three-way valve 53 may be connected to the first cylinder 21 through an air pipe, and a first one-way valve 55 and a pressure regulating valve 56 may be disposed on the air pipe between the three-way valve 53 and the first cylinder 21, wherein the pressure regulating valve 56 may be disposed near one end of the first cylinder 21. A second output port of the three-way valve 53 may communicate with the air pipe joint 44 through an air pipe, that is, the second output port of the three-way valve 53 communicates with the inflation mechanism 40. A second check valve 57 is provided on the air pipe between the three-way valve 53 and the air pipe joint 44.
It is understood that the watch glass opener may further include a controller (not shown) electrically connected to each electrical component of the watch glass opener, respectively, to control the operation of the watch glass opener.
When the watch glass 72 and the watch case 71 are detached, the watch 70 to be repaired can be placed on the mounting panel 11 such that the watch glass 72 faces the first pneumatic drive mechanism 20 and the watch case 71 faces the second pneumatic drive mechanism 30 on the side away from the watch glass 72. Meanwhile, the conduit 73 is connected to the flexible air nozzle 42 of the inflating mechanism 40.
The second direction valve 59 is actuated to make the air pump 51 supply air to the third air cylinder 61 to drive the third pressing block 62 to move towards the positioning block 63, so that the third pressing block 62 and the two positioning blocks 63 are matched to clamp the watchcase 71, and simultaneously, the end surface of one end of the flexible air faucet 42 far away from the sliding plate 41 is in sealing contact with the side wall of the watchcase 71.
The first reversing valve 58 acts to enable the air pump 51 to supply air to the second air cylinder 31 so as to drive the second pressing block 32 to press the meter case 71 onto the mounting panel 11, and limit of the meter case 71 is achieved. This also fixes the wristwatch case 71 to the mounting panel 11.
The on-off valve 54 is opened, and the air pump 51 supplies air to the first air cylinder 21 and the air charging mechanism 40, respectively. Specifically, the first cylinder 21 drives the first pressing block 22 to abut against the watch glass 72, and the inflating mechanism 40 inflates a certain amount of gas into the internal cavity of the watch 70 to be maintained. It will be appreciated that the watch glass 72 is always fixed relative to the watch case 71 during this time. When first press piece 22 abuts against cover glass 72, cover glass 72 is balanced in force. For example, the force applied to cover glass 72 by first press piece 22 may be equal to the force applied to cover glass 72 by the gas in the internal cavity. Of course, in other embodiments, the sum of the force exerted by first press piece 22 on watch glass 72 and the frictional force between watch glass 72 and watch case 71 may be equal to the force exerted by the gas in the internal cavity on watch glass 72.
The pressure regulating valve 56 is operated to gradually reduce the acting force of the first pressing block 22 on the watch glass 72, so that the acting force exerted on the side of the watch glass 72 close to the internal cavity is gradually larger than the sum of the acting force exerted on the side of the watch glass 72 close to the first pressing block 22 and the friction force between the watch glass 72 and the watch case 71. Thereby, the watch glass 72 is gradually pushed by the gas in the internal cavity and gradually separated from the watch case 71.
After the watch glass 72 is completely separated from the watch case 71, the on-off valve 54 is closed and the pressure regulating valve 56 is reset. The first and second direction valves 58, 59 are actuated simultaneously or sequentially to release the watch case 71 to facilitate removal of the detached watch 70 to be serviced by the user.
Therefore, the problems of splashing, collision, loss and the like of the watch glass 72 and the movement and other structures positioned in the inner cavity can be avoided. Meanwhile, the operation is more convenient and safer.
As shown in fig. 6, the embodiment further provides a watch glass opening method, which can be implemented based on the watch glass opener provided in the embodiment. The watch glass opening method comprises the following steps:
s10, placing the watch 70 to be repaired on the rack 10, making the watch glass 72 opposite to the first pneumatic driving mechanism 20, making the side of the watch case 71 opposite to the watch glass 72 opposite to the second pneumatic driving mechanism 30, and making the conduit 73 in plug-in communication with the inflating mechanism 40.
Specifically, the conduit 73 may be in plug communication with the flexible air nozzle 42 of the inflation mechanism 40.
S20, case 71 is fixed to rack 10.
Specifically, first, the second direction changing valve 59 of the air supply mechanism 50 is operated, and air is supplied to the third cylinder 61 by the air pump 51, so that the third presser 62 and the two positioning blocks 63 are fitted in the circumferential direction of the case 71 to clamp the case 71. At the same time, the end face of flexible air tap 42 can be abutted against the side wall of watchcase 71 in a sealing manner.
Subsequently, the first direction changing valve 58 is actuated to supply air to the second cylinder 31 by the air pump 51, and the second presser 32 presses the case 71. Thereby, the fixing of the case 71 to the rack 10 can be achieved.
S30, the first pneumatic drive mechanism 20 and the inflating mechanism 40 are supplied with air from the air supply mechanism 50, respectively, and the first pneumatic drive mechanism 20 is caused to interlock with the inflating mechanism 40 to separate the glass 72 from the case 71.
Specifically, the on-off valve 54 is opened, and the air pump 51 supplies air to the first air cylinder 21 and the flexible air faucet 42, respectively. The first air cylinder 21 drives the first presser block 22 against the watch glass 72. The flexible air cap 42 may inflate the internal cavity of the watch 70 to be serviced. When first presser piece 22 abuts on cover glass 72, cover glass 72 is balanced in force. It will be appreciated that during this time, the watch glass 72 may remain fixed relative to the watch case 71.
Subsequently, the pressure regulating valve 56 operates to gradually decrease the pressure applied to the watch glass 72 by the first pressure block 22. So that the force applied to the side of the watch glass 72 close to the internal cavity is gradually larger than the sum of the force applied to the watch glass 72 by the first press piece 22 and the frictional force between the watch glass 72 and the watch case 71. Thus, the watch glass 72 can be gradually separated from the watch case 71 under the urging action of the gas, i.e., the separation of the watch glass 72 from the watch case 71 is realized.
S40, releasing the watch 70 to be repaired.
Specifically, after the watch glass 72 is completely separated from the watch case 71, the open/close valve 54 is closed and the pressure regulating valve 56 is reset. First diverter valve 58 and second diverter valve 59 are actuated simultaneously or sequentially to release watch case 71 to facilitate the user removing the detached watch 70 to be serviced from the watch glass opener.
