[0010] More preferably, it further comprises an electric actuator II and a top plate; at least two electric actuators II are fixedly connected to the lower die; and each telescopic part of the electric actuator II is fixedly connected to a top plate.

[0011] More preferably, a protrusion matching the through hole on the watch case is provided on the top plate, and the protrusion is made of rubber.

[0012] More preferably, a detection system is also included; each transmission shaft I is connected to a detection system; the detection system includes a fixed ring, an air duct and a pressure gauge; each transmission shaft I has at least four through holes equidistantly opened in a ring in the middle; each transmission shaft I rotates and is connected to a fixed ring in the middle; each fixed ring is fixedly connected and connected to at least two air ducts; all air ducts pass through the lower mold, and all air ducts located in the front are fixedly connected to a pressure gauge.

[0013] More preferably, the lower portion of the transmission shaft I is a solid structure.

[0014] The advantages and positive effects of the present invention are: (1) By moving the top plate, the top plate is brought close to the through hole on the case and inserted into the through hole on the case to detect the through hole on the case, thereby realizing the detection of the through hole on the case before the case and the aluminum ring are pressed together, thereby preventing defective products from flowing into subsequent processes, effectively improving the quality of the finished product and reducing production costs.

[0015] (2) The case is limited by a limit block, and then the gas is blown to the surface of the case through all the conduits to clean the case. The aluminum ring is then cleaned manually. Since the structure of the aluminum ring is simpler than that of the case, it only needs to be wiped manually to clean the case and the aluminum ring, thereby improving the pressing efficiency of the case and the aluminum ring.

[0016] (3) By rotating the watch case and the aluminum ring at the same time, the watch case and the aluminum ring are pressed together while rotating, so that the force on the watch case and the aluminum ring is more uniform, so that the aluminum ring can fit better with the watch case and improve the sealing of the watch case and the aluminum ring.

[0017] (4) Allow gas to enter the transmission shaft I and fill the entire chamber, then maintain pressure on the case and aluminum ring for a preset time and observe the value on the pressure gauge. If the value on the pressure gauge is within the preset pressure range, it means that the sealing of the case and aluminum ring is qualified and meets the production standards. On the contrary, if the value on the pressure gauge is lower than the preset pressure range, it means that the sealing of the case and aluminum ring is unqualified, thereby achieving a sealing test on the pressed case and aluminum ring.

[0018] (5) By pumping water into the transmission shaft I and filling the entire chamber with water, the watch case and the aluminum ring are both in contact with water, and then the watch case and the aluminum ring are kept under pressure. By observing whether water overflow occurs on the outside of the pressed part of the watch case and the aluminum ring, the waterproof performance of the watch case and the aluminum ring is determined, thereby realizing the waterproof test of the pressed watch case and the aluminum ring. Compared with the existing technology, the sealedness test and waterproof test of the pressed watch case and the aluminum ring from the inside out can simulate the internal pressure changes that the watch may encounter in daily use, such as the air pressure changes caused by temperature changes or the tiny pressure generated when the internal movement of the watch is operating. It can focus on the sealing of the internal structure of the watch case and the aluminum ring, ensure that the internal movement and parts are not affected by the external environment, thereby ensuring that the watch can maintain excellent performance and service life under various environmental conditions.

[0028] It also includes an electric actuator II 211 and a top plate 212 ; two electric actuators II 211 are fixedly connected to the lower mold 207 , and the electric actuators II 211 are electric push rods; and each telescopic part of the electric actuator II 211 is fixedly connected to a top plate 212 .

[0029] The top plate 212 is provided with a bump that matches the through hole 51 on the watch case 5 , and the bump is made of rubber material to prevent the watch case 5 from being scratched.

[0030] When cleaning the watch case 5 and the aluminum ring 6: connect the external air pump to the two air inlet pipes 2041 in advance, and then manually place the two watch cases 5 in the lower mold 207, and limit the watch cases 5 by a limit block 210, as shown in FIG. Figure 6 As shown, the watch case 5 is provided with a through hole 51. For the convenience of discussion, a watch case 5 and an aluminum ring 6 are taken as an example. Since the watch case 5 and the aluminum ring 6 are prone to dust during transportation, and the existing pressing equipment cannot clean the watch case 5 and the aluminum ring 6 before pressing, the watch case 5 and the aluminum ring 6 need to be cleaned manually before pressing, which leads to low pressing efficiency of the watch case 5 and the aluminum ring 6. After the watch case 5 is placed on the limit block 210, since the watch case 5 is provided with a through hole 51 for inserting the watch case 5, the watch case 5 and the aluminum ring 6 are provided with a through hole 51. The through hole 51 of the crown needs to be accurate to prevent the through hole 51 from being deflected, which may cause errors in the assembly of the crown and affect the quality of the final product. The electric actuator II 211 is controlled to start and drive the top plate 212 to move, so that the top plate 212 is close to the through hole 51 on the case 5 and inserted into the through hole 51 on the case 5. If the top plate 212 can be smoothly inserted into the through hole 51 on the case 5, it means that the through hole 51 is not deflected. On the contrary, if the top plate 212 cannot be smoothly inserted into the case 5 If the through hole 51 on the watch case 5 is found to be deflected, it means that the through hole 51 is deflected, that is, the watch case 5 is a defective product. The watch case 5 is then taken out manually, so that the through hole 51 on the watch case 5 can be detected before the watch case 5 and the aluminum ring 6 are pressed together, thereby preventing defective products from flowing into the subsequent processes, effectively improving the quality of the finished product and reducing the production cost. The electric actuator I2 is then controlled to start and drive the sliding plate 3 to move downward, thereby driving all the connected parts to move, and then driving the pressure ring 203 to move downward close to the watch case 5, and then controlling the outer An air pump is operated to supply air to the two air inlet pipes 2041, so that the gas enters the guide ring 204 through the air inlet pipes 2041, and finally blows to the surface of the watch case 5 through all the ducts 206, thereby blowing the gas to the surface of the watch case 5 through all the ducts 206 to clean the watch case 5, and then the aluminum ring 6 is cleaned manually. Since the structure of the aluminum ring 6 is simpler than that of the watch case 5, it only needs to be wiped manually, thereby cleaning the watch case 5 and the aluminum ring 6 and improving the pressing efficiency of the watch case 5 and the aluminum ring 6.

[0031] When the watch case 5 and the aluminum ring 6 are pressed together: the electric actuator I2 is controlled to start and drive the sliding plate 3 to move upward, thereby driving all the connected parts to move, thereby moving the pressing ring 203 upward and away from the watch case 5, and then placing the wiped aluminum ring 6 in the pressing ring 203, and controlling the external pump to start to pump air, thereby generating negative pressure in the air inlet pipe 2041, thereby generating negative pressure in the guide ring 204, the limit ring 205, the conduit 206 and the pressing ring 203, and then passing through the pressing ring 2 03 is used to adsorb and limit the aluminum ring 6, and then the electric actuator Ⅰ2 is controlled in the same way as above to start and drive the sliding plate 3 to move downward, thereby driving all the connected parts to move, so that the pressure ring 203 moves close to the lower die 207, and the aluminum ring 6 is pressed against the watch case 5. Due to the existing pressing equipment, the watch case 5 and the aluminum ring 6 are difficult to maintain uniform force during pressing, which affects the fixing effect of the aluminum ring 6, and easily leads to reduced sealing and waterproof performance of the watch case 5 and the aluminum ring 6. The product quality is affected by controlling the motor Ⅱ 201 to start, the output shaft of the motor Ⅱ 201 rotates to drive the transmission shaft Ⅱ 202 to rotate, the transmission shaft Ⅱ 202 rotates to drive the pressure ring 203 to rotate, and the pressure ring 203 rotates to drive the aluminum ring 6 to rotate. At the same time, the motor Ⅰ 208 is started, the output shaft of the motor Ⅰ 208 rotates to drive the transmission shaft Ⅰ 209 to rotate, and the transmission shaft Ⅰ 209 drives the limit block 210 to rotate, and then the raised portion 2101 rotates to drive the case 5 to rotate, and the electric actuator Ⅰ 2 is controlled to start to drive the sliding plate 3 to continue to move downward, so that the case 5 and the aluminum ring 6 are pressed together while rotating, so that the force on the case 5 and the aluminum ring 6 is more uniform, so that the aluminum ring 6 can better fit with the case 5, and improve the sealing of the case 5 and the aluminum ring 6, and the conduit 206 used for air blowing cleaning can cooperate with the pressure ring 203 to adsorb and fix the aluminum ring 6, without the need to set up an additional aluminum ring 6 clamping mechanism, thereby effectively reducing the equipment maintenance cost and making it more convenient to use.

[0032] Embodiment 2: Based on the first embodiment, according to Figure 7-Figure 9 As shown, a detection system is also included; each transmission shaft Ⅰ209 is connected to a detection system; the detection system includes a fixed ring 301, an air guide tube 302 and a pressure gauge 303; each transmission shaft Ⅰ209 has four through holes equidistantly opened in a circular shape in the middle; each transmission shaft Ⅰ209 is rotated and connected to a fixed ring 301 in the middle; each fixed ring 301 is fixedly connected and connected to two air guide tubes 302; all air guide tubes 302 pass through the lower mold 207, and all air guide tubes 302 located in the front are fixedly connected to a pressure gauge 303.

[0033] The lower part of the transmission shaft I 209 is a solid structure, which is used to cooperate with the air guide pipe 302 to guide the gas and water, so that the gas and water can contact the watch case 5 and the aluminum ring 6 more quickly.

[0034] The external pump is connected to the air duct 302 at the front in advance, and another external air pump is connected to the air duct 302 at the rear. When all the ducts 206 blow gas to the surface of the watch case 5, some dust will fall into the limit block 210 and the cavity of the transmission shaft I 209. At this time, the other external air pump is controlled to start operating so that negative pressure is generated in the air duct 302 at the rear, thereby generating negative pressure in the limit block 210 and the cavity of the transmission shaft I 209, thereby sucking the dust that falls into the limit block 210 and the cavity of the transmission shaft I 209. 09, so as to cooperate with all the ducts 206 to absorb the dust on the case 5, so as to prevent dust from remaining in the limit block 210 and the cavity of the transmission shaft Ⅰ209. In addition, in order to strengthen quality control, after the case 5 and the aluminum ring 6 are pressed together, a comprehensive inspection of the pressed case 5 and the aluminum ring 6 is required, including appearance inspection, sealing test and waterproof test, etc., to ensure that the case 5 and the aluminum ring 6 are tightly combined without gaps or looseness. When the sealing test of the pressed case 5 and the aluminum ring 6 is carried out, the electric actuator Ⅰ is controlled. 2 is started to drive the sliding plate 3 to move upward, thereby driving all the connected parts to move, and then driving the pressure ring 203 to move upward, so that the middle part of the pressure ring 203 fits with the inner side of the aluminum ring 6, as shown in the figure, at this time, the pressure ring 203, the watch case 5, the aluminum ring 6, the transmission shaft I 209 and the limit block 210 together form a closed chamber, and then control the external air pump to operate to supply gas to the air guide tube 302, so that the gas enters the fixed ring 301 through the air guide tube 302, and finally the gas enters the transmission shaft I 209 and fills the entire The pressure of the watch case 5 and the aluminum ring 6 is maintained for a preset time, and the value on the pressure gauge 303 is observed. If the value on the pressure gauge 303 is within the preset pressure range, it means that the sealing of the watch case 5 and the aluminum ring 6 is qualified and meets the production standards. On the contrary, if the value on the pressure gauge 303 is lower than the preset pressure range, it means that the sealing of the watch case 5 and the aluminum ring 6 is unqualified and does not meet the production standards. At this time, the pressed watch case 5 and the aluminum ring 6 are taken out manually to achieve a sealing test of the pressed watch case 5 and the aluminum ring 6.

[0035] When performing a waterproof test on the pressed watch case 5 and aluminum ring 6, remove the air supply pipe on the external pump machine from the air pipe 302, then connect the external water pump to the air pipe 302, control the external water pump to supply water into the air pipe 302, so that the water enters the transmission shaft Ⅰ209 along the air pipe 302 and fills the entire chamber, so that the watch case 5 and the aluminum ring 6 can both come into contact with water, then maintain the pressure on the watch case 5 and the aluminum ring 6, and determine the waterproof performance of the watch case 5 and the aluminum ring 6 by observing whether water overflow occurs on the outside of the pressed part of the watch case 5 and the aluminum ring 6. If water does not overflow on the outside of the pressed part of the watch case 5 and the aluminum ring 6, it means that the waterproof performance of the watch case 5 and the aluminum ring 6 meets the standard. On the contrary, if the watch case 5 and the aluminum ring 6 are pressed If water overflows from the outside of the watch, it means that the waterproof performance of the watch case 5 and the aluminum ring 6 does not meet the standard. The pressed watch case 5 and the aluminum ring 6 are then taken out manually to perform a waterproof test on the pressed watch case 5 and the aluminum ring 6. Compared with the prior art, the pressed watch case 5 and the aluminum ring 6 are tested for sealing and waterproof from the inside out, which can simulate the internal pressure changes that the watch may encounter in daily use, such as the air pressure changes caused by temperature changes or the tiny pressure generated when the internal movement of the watch is operating. It can focus on the sealing of the internal structure of the watch case 5 and the aluminum ring 6, ensuring that the internal movement and parts are not affected by the external environment, thereby ensuring that the watch can maintain excellent performance and service life under various environmental conditions.

Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
