Technical Field

[0001] This invention belongs to the field of watch case processing, and specifically relates to an aluminum ring pressing device for watch case processing. Background Technology

However, the existing pressing equipment cannot clean the watch case and aluminum ring before pressing. As a result, the watch case and aluminum ring need to be cleaned manually before pressing, which leads to low pressing efficiency.

[0003] Furthermore, existing pressing equipment makes it difficult to maintain uniform stress on the watch case and aluminum ring during pressing, which affects the fixing effect of the aluminum ring and can easily reduce the sealing and waterproof performance of the watch case and aluminum ring, thus affecting product quality. Summary of the Invention

[0008] More preferably, the upper part of drive shaft I is configured as an inverted cone shape.

[0009] More preferably, the limiting block is a hollow structure, and the upper inner side of the limiting block is set as an inverted cone shape.

[0010] More preferably, the extrusion assembly includes an electric actuator I, a sliding plate, a base, a motor II, a drive shaft II, a guide ring, an air inlet pipe, a limiting ring, a guide tube, and a lower die; the electric actuator I is connected to the upper part of the frame; the sliding plate is fixedly connected to the telescopic part of the electric actuator I, and the sliding plate is slidably connected to the frame; the base is fixedly connected to the lower part of the frame; at least two motors II are mounted on the upper part of the sliding plate; each motor II output shaft is fixedly connected to a drive shaft II; each drive shaft II is fixedly connected to a pressure ring; a guide ring is rotatably connected to each drive shaft II, and the guide ring is hollow; each guide ring is fixedly connected to the sliding plate through a fixing rod; an air inlet pipe is connected to each guide ring; a limiting ring is rotatably connected to the lower part of each guide ring; at least four guide tubes are connected to each limiting ring; all guide tubes on the same limiting ring are fixedly connected to the corresponding pressure ring; the lower die is mounted on the upper surface of the base; the base is fixedly connected to all motors I; the base is rotatably connected to all drive shafts I.

[0011] More preferably, it also includes an electric actuator II and a top plate; at least two electric actuators II are fixedly connected to the lower mold; and each electric actuator II telescopic part is fixedly connected to a top plate.

[0012] More preferably, the top plate is provided with a protrusion that matches the through hole on the case, and the protrusion is made of rubber.

[0013] More preferably, it also includes a detection system; each drive shaft I is connected to a detection system; the detection system includes a retaining ring, an air guide tube and a pressure gauge; each drive shaft I has at least four through holes equidistantly spaced in the middle; each drive shaft I is rotatably connected to a retaining ring in the middle; each retaining ring is fixedly connected to and connected to at least two air guide tubes; all air guide tubes pass through the lower mold, and a pressure gauge is fixedly connected to all air guide tubes located at the front.

[0014] More preferably, the lower part of drive shaft I is a solid structure.

[0015] The advantages and positive effects of this invention are:

[0016] (1) By moving the top plate, the top plate is brought close to the through hole on the watch case and inserted into the through hole on the watch case to inspect the through hole on the watch case. This allows the through hole on the watch case to be inspected before the watch case and 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.

[0017] (2) The watch case is limited by the limiting block, and the gas is blown to the surface of the watch case through all the conduits to clean the watch case. The aluminum ring is then cleaned manually. Since the structure of the aluminum ring is simpler than that of the watch case, it can be simply wiped by hand, thereby cleaning the watch case and the aluminum ring and improving the pressing efficiency of the watch case and the aluminum ring.

[0018] (3) By rotating the watch case and the aluminum ring simultaneously, 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, the aluminum ring can fit better with the watch case, and the sealing performance of the watch case and the aluminum ring is improved. In addition, the tube used for air cleaning can cooperate with the pressure ring to adsorb and fix the aluminum ring, without the need for an additional aluminum ring clamping mechanism, which can effectively reduce equipment maintenance costs and make it more convenient to use.

[0019] (4) By allowing gas to enter the drive shaft I and fill the entire chamber, and then pressurizing the watch case and aluminum ring for a preset time, the value on the pressure gauge is observed. If the value on the pressure gauge is within the preset pressure range, it indicates that the sealing performance of the watch case and aluminum ring is qualified and meets the production standards. Conversely, if the value on the pressure gauge is lower than the preset pressure range, it indicates that the sealing performance of the watch case and aluminum ring is unqualified. This achieves the sealing performance test of the pressed watch case and aluminum ring.

[0020] (5) By pumping water into the drive shaft I and filling the entire chamber with water, the watch case and the aluminum ring can come into contact with water. Then, the watch case and the aluminum ring are pressurized, and the waterproof performance of the watch case and the aluminum ring is determined by observing whether water overflow occurs on the outside of the pressed joint. This allows for a waterproof test of the pressed watch case and the aluminum ring. Compared with existing technologies, this method of testing the sealing and waterproof performance of the pressed watch case and the aluminum ring from the inside out can simulate the internal pressure changes that a watch may encounter in daily use, such as air pressure changes caused by temperature changes or the small pressure generated when the watch movement is running. It can focus on the sealing performance of the internal structure of the watch case and the aluminum ring, 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.

[0032] Example 1:

[0033] An aluminum ring pressing device for watch case processing, according to Figures 1-6 As shown, it includes a frame 1;

[0034] It also includes an extrusion assembly, a pressure ring 203, a motor I 208, a drive shaft I 209, and a limiting block 210; the extrusion assembly is connected to the frame 1; two pressure rings 203 are connected to the extrusion assembly; two motors I 208 are mounted on the extrusion assembly; each motor I 208 output shaft is fixedly connected to a drive shaft I 209; all drive shafts I 209 are connected to the extrusion assembly; each drive shaft I 209 is fixedly connected to a limiting block 210, and the limiting block 210 is provided with a protrusion 2101.

[0035] The upper inner side of the pressure ring 203 is inclined to fit the upper surface of the aluminum ring 6.

[0036] The lower part of the pressure ring 203 is made of rubber to prevent scratches on the case 5 and the aluminum ring 6.

[0037] The upper part of the drive shaft I209 is designed with an inverted cone shape to guide dust.

[0038] The limiting block 210 has a hollow structure, and the upper inner side of the limiting block 210 is set as an inverted cone shape to guide dust.

[0039] The extrusion assembly includes an electric actuator I2, a sliding plate 3, a base 4, a motor II201, a drive shaft II202, a guide ring 204, an air inlet pipe 2041, a limit ring 205, a guide tube 206, and a lower die 207; the upper part of the frame 1 is connected to the electric actuator I2, which is an electric push rod; the sliding plate 3 is fixedly connected to the telescopic part of the electric actuator I2, and the sliding plate 3 is slidably connected to the frame 1; the lower part of the frame 1 is fixedly connected to the base 4; two motors II201 are mounted on the upper part of the sliding plate 3; each motor II201 output shaft is fixedly connected to a drive shaft II202; each drive shaft II202 is fixedly connected to a pressure ring 203; each drive shaft II202 is fixedly connected to a pressure ring 203; each drive shaft II202 output ... Each shaft II 202 is rotatably connected to a guide ring 204, and the guide ring 204 is hollow; each guide ring 204 is fixedly connected to the sliding plate 3 by two fixed rods; each guide ring 204 is fixedly connected to and connected to an air inlet pipe 2041; each guide ring 204 is rotatably connected to a limiting ring 205 at its lower part; each limiting ring 205 is fixedly connected to and connected to four conduits 206; all conduits 206 on the same limiting ring 205 are fixedly connected to the corresponding pressure ring 203; a lower mold 207 is installed on the upper surface of the base 4; the base 4 is fixedly connected to all motors I 208; the base 4 is rotatably connected to all drive shafts I 209.

[0040] It also includes an electric actuator II211 and a top plate 212; two electric actuators II211 are fixedly connected to the lower mold 207, and the electric actuators II211 are electric push rods; each electric actuator II211 has a top plate 212 fixedly connected to its telescopic part.

[0041] The top plate 212 is provided with a protrusion that matches the through hole 51 on the watch case 5, and the protrusion is made of rubber to prevent scratches on the watch case 5.

[0042] When cleaning the watch case 5 and the aluminum bezel 6: The external air pump is connected to two air inlet pipes 2041 beforehand. Then, both watch cases 5 are manually placed inside the lower mold 207, and each is limited by a limiting block 210. Figure 6 As shown, the watch case 5 has a through hole 51. For ease of discussion, the following will take a watch case 5 and an aluminum ring 6 as an example. Since the watch case 5 and the aluminum ring 6 are prone to dust accumulation 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, resulting in low pressing efficiency. After placing the watch case 5 on the limiting block 210, since the watch case 5 has a hole for inserting the watch... The crown has a through hole 51. Therefore, the accuracy of the through hole 51 must be ensured to prevent misalignment of the through hole 51, which could cause assembly errors in the crown and affect the final product quality. The electric actuator II 211 is activated to move the top plate 212, bringing it closer to and inserting it into the through hole 51 on the watch case 5. If the top plate 212 can be smoothly inserted into the through hole 51 on the watch case 5, it indicates that the through hole 51 is not misaligned. Conversely, if the top plate 212 cannot be smoothly inserted into the watch case 5, it indicates that the through hole 51 is not misaligned. If the through hole 51 on the watch case 5 is misaligned, it indicates that the watch case 5 is a defective product. The watch case 5 is then manually removed. This allows for inspection of the through hole 51 on the watch case 5 before it is pressed together with the aluminum ring 6, preventing defective products from entering subsequent processes, effectively improving the quality of the finished product and reducing production costs. Then, the electric actuator I2 is activated, causing the sliding plate 3 to move downwards, which in turn moves all connected components, causing the pressure ring 203 to move downwards closer to the watch case 5. Finally, the outer... An air pump operates to supply air into two air inlet pipes 2041, allowing the gas to enter the guide ring 204 through the air inlet pipes 2041. Finally, the gas is blown onto the surface of the watch case 5 through all the conduits 206, thereby cleaning the watch case 5. The aluminum bezel 6 is then cleaned manually. Since the structure of the aluminum bezel 6 is simpler than that of the watch case 5, it only requires simple wiping by hand. This achieves the cleaning of both the watch case 5 and the aluminum bezel 6 and improves the pressing efficiency of the watch case 5 and the aluminum bezel 6.

[0043] When pressing the watch case 5 and the aluminum ring 6 together: the electric actuator I2 is activated to move the sliding plate 3 upward, which in turn moves all connected components, causing the pressure ring 203 to move upward away from the watch case 5. The wiped aluminum ring 6 is then placed inside the pressure ring 203, and the external pump is activated to draw air, creating a negative pressure in the air inlet pipe 2041. This negative pressure then forms in the guide ring 204, the limit ring 205, the guide tube 206, and the pressure ring 203, thus allowing air to pass through the pressure ring 203. 03. The aluminum ring 6 is adsorbed and limited, and then the electric actuator I2 is started in the same way as above, driving the sliding plate 3 to move downward, thereby driving all connected parts to move, so that the pressure ring 203 moves closer to the lower mold 207, and the aluminum ring 6 abuts against the watch case 5. Because the existing pressing equipment makes it difficult to keep the force on the watch case 5 and the aluminum ring 6 uniform during pressing, the fixing effect of the aluminum ring 6 is affected, and the sealing and waterproof performance of the watch case 5 and the aluminum ring 6 are easily reduced. To improve product quality, the motor II 201 is started, and its output shaft rotates, driving the transmission shaft II 202 to rotate. The transmission shaft II 202 then drives the pressure ring 203 to rotate, which in turn drives the aluminum ring 6 to rotate. Simultaneously, the motor I 208 is started, and its output shaft rotates, driving the transmission shaft I 209 to rotate. The transmission shaft I 209 then drives the limit block 210 to rotate, which in turn drives the watch case 5 to rotate via the protrusion 2101. The electric actuator I 2 is then started, causing the sliding plate 3 to continue moving downwards. This causes the watch case 5 and the aluminum ring 6 to press together while rotating, resulting in more even force distribution on the watch case 5 and the aluminum ring 6. This allows the aluminum ring 6 to better fit the watch case 5 and improves the sealing performance of the watch case 5 and the aluminum ring 6. Furthermore, the air-blowing cleaning conduit 206 can cooperate with the pressure ring 203 to adsorb and fix the aluminum ring 6, eliminating the need for an additional aluminum ring 6 clamping mechanism. This effectively reduces equipment maintenance costs and makes the equipment more convenient to use.

[0044] Example 2:

[0045] Based on Example 1, according to Figures 7-9 As shown, it also includes a detection system; each drive shaft I 209 is connected to a detection system; the detection system includes a fixed ring 301, an air guide pipe 302 and a pressure gauge 303; each drive shaft I 209 has four through holes equidistantly spaced in the middle; each drive shaft I 209 has a fixed ring 301 that rotates and is connected to the middle; each fixed ring 301 has two air guide pipes 302 that are fixedly connected and connected to it; all air guide pipes 302 pass through the lower mold 207, and a pressure gauge 303 is fixedly connected to all the air guide pipes 302 located at the front.

[0046] The lower part of the drive shaft I209 is a solid structure, which is used to cooperate with the air guide tube 302 to guide gas and water, so that the gas and water can come into contact with the watch case 5 and the aluminum ring 6 more quickly.

[0047] An external pump is connected to the front air duct 302, and another external air pump is connected to the rear air duct 302. When all the ducts 206 blow gas toward the surface of the case 5, some dust will fall into the cavity of the limiting block 210 and the drive shaft I 209. At this time, the other external air pump is started to create a negative pressure in the rear air duct 302, which in turn creates a negative pressure in both the limiting block 210 and the cavity of the drive shaft I 209, thereby sucking up the dust that has fallen into the limiting block 210 and the cavity of the drive shaft I 209. The dust inside the cavity of 09 is removed, thus cooperating with all the conduits 206 to suck away the dust on the watch case 5, preventing dust from remaining in the limit block 210 and the cavity of the drive shaft I 209. Furthermore, to enhance quality control, after the watch case 5 and aluminum ring 6 are pressed together, a comprehensive inspection of the pressed watch case 5 and aluminum ring 6 is required, including visual inspection, sealing tests, and waterproof tests, to ensure that the watch case 5 and aluminum ring 6 are tightly joined without gaps or looseness. During the sealing test of the pressed watch case 5 and aluminum ring 6, the electric actuator I is controlled. 2. The starting mechanism moves the sliding plate 3 upwards, which in turn moves all connected components, causing the pressure ring 203 to move upwards. This causes the middle part of the pressure ring 203 to fit against the inner side of the aluminum ring 6, as shown in the figure. At this point, the pressure ring 203, the case 5, the aluminum ring 6, the drive shaft I 209, and the limiting block 210 together form a sealed chamber. Then, the external air pump is controlled to supply air into the air guide pipe 302, allowing the gas to enter the fixed ring 301 through the air guide pipe 302, and finally, the gas enters the drive shaft I 209 and fills the entire chamber. In the chamber, the pressure of the watch case 5 and 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 indicates that the sealing performance of the watch case 5 and aluminum ring 6 is qualified and meets the production standards. Conversely, if the value on the pressure gauge 303 is lower than the preset pressure range, it indicates that the sealing performance of the watch case 5 and aluminum ring 6 is unqualified and does not meet the production standards. At this time, the pressed watch case 5 and aluminum ring 6 are manually removed to perform a sealing performance test on the pressed watch case 5 and aluminum ring 6.

[0048] During the waterproof test of the pressed watch case 5 and aluminum ring 6, the air supply pipe on the external pump was disconnected from the air duct 302. The external water pump was then connected to the air duct 302, and the pump was controlled to supply water into the air duct 302, allowing the water to flow along the air duct 302 into the drive shaft I209 and fill the entire chamber. This ensured that both the watch case 5 and aluminum ring 6 could come into contact with water. Pressure was then applied to the watch case 5 and aluminum ring 6, and the waterproof performance of the watch case 5 and aluminum ring 6 was determined by observing whether water overflow occurred at the pressed joint. If no water overflow occurred at the pressed joint, the waterproof performance of the watch case 5 and aluminum ring 6 met the standard; otherwise, if water overflow occurred, the waterproof performance of the watch case 5 and aluminum ring 6 was deemed satisfactory. If water overflows from the outside of the case 5 and the aluminum ring 6, it indicates that the water resistance of the case 5 and the aluminum ring 6 is substandard. The case 5 and the aluminum ring 6 are then manually removed to perform a water resistance test on them. Compared with existing technologies, this method of testing the sealing and water resistance of the case 5 and the aluminum ring 6 from the inside out can simulate the internal pressure changes that a watch may encounter in daily use, such as air pressure changes caused by temperature changes or the minute pressure generated when the watch movement is operating. It can focus on the sealing of the internal structure of the 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 maintains excellent performance and service life under various environmental conditions.
