DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0029] like Figures 3 to 6 As shown: This embodiment discloses an electronic watch bottom shell and front shell disassembly device, including a base assembly and an upper disassembly assembly, the base assembly includes a base 1 and a clamping claw 11, the base 1 is provided with a product groove 101 matching the contour of the watch bottom shell, the clamping claw 11 is retractably connected to the product groove 101, and the clamping claw 11 is used to connect the watch bracelet connection. Specifically, the two ends of the product groove 101 are provided with clamping claw holes 102, the clamping claw 11 passes through the clamping claw holes 102, and the driving mechanism of the clamping claw 11 is a clamping cylinder 12.

[0030] The upper disassembly assembly includes a profiling heating head 2 and a clamping claw assembly. The clamping claw assembly is connected to the lifting plate 7. The lifting plate 7 can slide relative to the base assembly. The profiling heating head 2 is connected to the lifting plate 7 through an elastic guide rod 21. The overall structure of the profiling heating head 2 is a copper block, and a plurality of heating rods are arranged inside it. The contour of the product connection surface of the profiling heating head 2 is preferably able to fit the upper surface of the product, which is conducive to increasing the heating area.

[0031] Specifically, the jaw assembly includes a jaw sleeve 3, a plurality of slidable jaws 8 disposed inside the jaw sleeve 3, and a jaw sleeve driving device for driving the jaws 8 to slide relative to the jaw sleeve 3. The jaw sleeve driving device of this embodiment is a pull rod 9, one end of which is provided with a wedge head 91, the jaw 8 is provided with a wedge surface connected to the wedge head 91, and the pull rod 9 is connected to the pull rod driving device. The pull rod driving device of this embodiment is a jaw cylinder 4, and the power output end of the jaw cylinder 4 is connected to the pull rod 9. The relative sliding between the wedge head 91 and the wedge surface of the jaw 8 is achieved by the extension and retraction of the jaw cylinder 4, thereby achieving the opening or closing of the jaw 8.

[0032] The specific structure of the clamping jaw 8 in this embodiment that can be slidably connected to the inside of the clamping jaw cover 3 is as follows: the clamping jaw 8 is provided with a guide column 81, which is inserted into the inside of the clamping jaw cover 3 and can be slidably connected to the clamping jaw cover 3, and a spring 82 for separating the clamping jaw 8 from the front shell is also provided between the clamping jaw 8 and the clamping jaw cover 3. That is, the elasticity of the spring 82 drives the clamping jaw 8 to move toward the wedge-shaped head 91, ensuring that the wedge-shaped surface of the clamping jaw 8 can fit the wedge-shaped head 91 tightly.

[0033] Since the front shell of the electronic watch ( Figure 1 ) is usually a rectangle. In order to ensure that the four sides of the front shell are subjected to force during disassembly, the present embodiment has four clamping jaws 8, and the four clamping jaws 8 form a rectangle. When working, the four clamping jaws 8 can grasp the four sides of the front shell at the same time.

[0034] Specifically, the present embodiment further comprises a vertical plate 5, which is preferably perpendicular to the base assembly, and the specific structure in which the lifting plate 7 can slide relative to the base assembly is: the lifting plate 7 is connected to the vertical plate 5 through a vertical slide rail 51. The vertical slide rail 51 is installed on the lifting plate 7, and a slider matching the vertical slide rail 51 is installed on the lifting plate 7, so that the lifting and lowering motion of the lifting plate 7 is realized, and the power for the lifting and lowering motion can adopt any one of the existing technologies such as a cylinder, a motor screw assembly, etc.

[0035] When the lifting plate 7 moves to a certain position, it can be locked in this state, but the movement accuracy of the lifting plate 7 is usually not too high, and it is usually used to adjust the entire working range. Therefore, the lifting plate 7 of this embodiment is also connected to the motor 6, and the power output end of the motor 6 is connected to the pull rod drive device through the screw assembly 61. The motor 6 is preferably a servo motor with high transmission accuracy, and the screw assembly 61 is preferably a ball screw with high transmission accuracy. This is because the gap between the inner edge of the front shell and the base is small, and the clamping jaw 8 has a certain thickness. Therefore, in order for the clamping jaw 8 to accurately enter between the inner edge of the front shell and the base, a higher transmission accuracy is required. The ball screw is connected to the power output end of the servo motor, and the nut matched with it is installed on the pull rod drive device (i.e., the clamping jaw cylinder 4). The movement of the entire clamping jaw assembly relative to the product is achieved by the rotation of the motor 6.

[0036] During operation, the bottom shell of the watch is placed inside the product slot 101, and the locking of the product by the claw 11 is achieved by the contraction of the clamping cylinder 12. Then the entire lifting plate 7 is driven to descend, so that the entire upper disassembly assembly descends, so that the contoured heating head 2 fits tightly against the upper surface of the product, and the elastic guide rod 21 is in a certain compression position, so that the contoured heating head 2 can exert a certain fitting force on the product, which is beneficial to heat conduction. The contoured heating head 2 is energized, and when the heating temperature and heating time meet the heating requirements, the motor 6 is rotated to drive the jaw assembly to descend, so that the jaw 8 descends to a position where it can clamp the front shell, and then the jaw cylinder 4 contracts to cause relative sliding between the wedge head 91 and the wedge surface of the jaw 8 (see Figure 6 ), and then the clamping jaws 8 are opened horizontally, so that all the clamping jaws 8 can clamp the front shell. Then, the motor 6 rotates in the opposite direction, driving the clamping jaw assembly to rise to pull the front shell and the bottom shell apart. During the separation process, the clamping jaws 8 should always remain in the open (clamping) state. In fact, when the clamping jaws 8 clamp the front shell, the front shell and the bottom shell can also be separated by directly lifting the entire upper disassembly assembly.

[0037] Since the separation force between the front shell and the bottom shell may be relatively large, in order to prevent the bottom shell from loosening due to insufficient clamping force of the claw 11 during the disassembly process, the present embodiment further provides a clamping plate 71 for connecting the claw 11 on the lifting plate 7. During the disassembly process, the clamping plate 71 can firmly clamp the two ends of the claw 11 to prevent the claw 11 from loosening.

[0038] When the disassembly is completed, the wedge head 91 is loosened by the clamping jaw cylinder 4, and the clamping jaw 8 can be separated from the front shell under the action of the spring 82.

[0039] Compared with the prior art, this embodiment can heat the product before separation, and the heating process reduces the connection strength of the sealant, making it easy to separate the front shell from the bottom shell. The clamping jaws 8 of this embodiment can be opened synchronously and can clamp the four sides of the front shell at the same time, making the disassembly force more uniform and avoiding damage to the product during the disassembly process.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
