[0016] The beneficial effects of this utility model are as follows: This utility model is used to fix plastic parts to be welded during laser welding. Specifically, it is used for fixing plastic parts during laser welding of a three-way valve. The system includes a base, a flat pressure drive mechanism, a rotary drive mechanism, a clamping assembly, a support member, and a limiting member. Both the flat pressure drive mechanism and the rotary drive mechanism are connected to the base. The mounting end of the clamping assembly is driven by the rotary drive mechanism.

[0027] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described in detail with reference to specific embodiments, but this is not intended to limit the present invention.

[0028] like Figure 1As shown in one embodiment of this utility model, a flat pressure device is used to fix a plastic part to be welded during laser welding. It is used to fix a plastic part when laser welding a three-way valve. The device includes a base 1, a flat pressure drive mechanism 2, a rotary drive mechanism 3, a clamping assembly 4, a support member 5, and a limiting member 6. The flat pressure drive mechanism 2 and the rotary drive mechanism 3 are both connected to the base 1. The mounting end of the clamping assembly 4 is drivenly connected to the rotary drive mechanism 3. The mounting end of the clamping assembly 4 refers to the end of the clamping assembly 4 used for connection to the rotary drive mechanism 3. One end of the support member 5 is drivenly connected to the flat pressure drive mechanism 2. One end of the limiting member 6 is rotatably connected to the support member 5 to facilitate rotation of the three-way valve. The limiting member 6 is correspondingly arranged to the clamping end of the clamping assembly 4. The clamping end of the clamping assembly 4 refers to the end of the clamping assembly 4 used for connection to the rotary drive mechanism 3. The flat pressure drive mechanism 2, used to clamp one end of the plastic part, can be a three-axis telescopic cylinder. One end of the support member 5 is connected to the telescopic rod end of the three-axis telescopic cylinder. The flat pressure drive mechanism 2 can drive the limiting member 6 to reciprocate in the X direction. The rotary drive mechanism 3 can drive the clamping assembly 4 to rotate. One end of the plastic part is brought into contact with the limiting member 6. The clamping assembly 4 is activated to clamp the other end of the plastic part. The flat pressure drive mechanism 2 is activated to push the plastic part towards the clamping assembly 4. Then the rotary drive mechanism 3 drives the clamping assembly 4 to rotate. The clamping assembly 4 then drives the plastic part to rotate, so that the laser welding machine can weld around the joint of the plastic part. The position of the clamping assembly 4 remains unchanged, so that the displacement of the plastic part is small, making it easy to confirm the welding position, thereby achieving the purpose of optimizing the clamping effect and improving the welding efficiency.

[0029] In some of these implementations, such as Figure 1 and 2 As shown, the pressure-regulating device also includes a transverse drive mechanism 7. The bottom of the base 1 is drivenly connected to the transverse drive mechanism 7, enabling the base 1 to reciprocate along the X direction, facilitating the user to adjust the three-way valve to be welded to the optimal welding position. The transverse drive mechanism 7 is a lead screw linear module, and the slider of the lead screw linear module is connected to the bottom of the base 1.

[0030] Specifically, in some implementations, such as Figure 1 and 2As shown in Figure 4, the flat pressing device also includes a positioning mechanism 8. The positioning mechanism 8 includes a base 81, a first feeding platform 82, a second feeding platform 83, and a lifting drive assembly 84. The first feeding platform 82 and the lifting drive assembly 84 are both connected to the base 81. The second feeding platform 83 is drivenly connected to the lifting drive assembly 84 so that the second feeding platform 83 can move to the side of the first feeding platform 82. The lifting drive assembly 84 can be a telescopic cylinder. The first feeding platform 82 and the second feeding platform 83 can both be located between the limiting member 6 and the clamping assembly 4. The user can place the three-way valve to be welded on the first feeding platform 82, so that one pipe port of the three-way valve is fitted onto one end of the limiting member 6. The clamping assembly 4 is used to clamp the other pipe of the three-way valve. The flat pressure drive mechanism 2 drives the support member 5, which in turn moves the limiting member 6 closer to the clamping assembly 4, allowing the plastic parts of the three-way valve to fit together. Then, the transverse drive mechanism 7 is activated to move the three-way valve to the welding position. The top of the first feeding platform 82 has a first semi-circular groove, and the top of the second feeding platform 83 has a second semi-circular groove that matches the first semi-circular groove. The user can place the three-way valve on the first feeding platform 82... The top of the feeding platform 82 and the second feeding platform 83 allows one pipe port of the three-way valve to be fitted onto one end of the limiting member 6. The clamping assembly 4 clamps the other pipe of the three-way valve. Then, the flat pressure drive mechanism 2 drives the limiting member 6 to hold the three-way valve in place. The lifting drive assembly 84 lowers the second feeding platform 83. Finally, the transverse drive mechanism 7 is activated to move the three-way valve to the welding position. Through the cooperation of the lifting drive assembly 84 and the second feeding platform 83, a foolproof effect can be achieved, preventing the user from not placing the three-way valve in the standard position. The standard position refers to the semi-circular groove at the top of the first feeding platform 82 and the second feeding platform 83.

[0031] In some of these implementations, such as Figure 2 and 3 As shown, the clamping assembly 4 includes a first gripper 41, a second gripper 42, and a gripper cylinder 43. The gripper cylinder 43 is driven to be connected to the rotary drive mechanism 3. One end of the first gripper 41 is driven to be connected to one output end of the gripper cylinder 43, and one end of the second gripper 42 is driven to be connected to the other output end of the gripper cylinder 43. A clamping area is formed between the first gripper 41 and the second gripper 42. One end of the three-way valve is placed in the clamping area, and then the gripper cylinder 43 drives the first gripper 41 and the second gripper 42 to clamp them.

[0032] In some of these implementations, such as Figure 2 and 3 As shown, the rotary drive mechanism 3 includes a transmission shaft 31 and a drive motor 32. The drive motor 32 is connected to the base 1. One end of the transmission shaft 31 is connected to the output shaft of the drive motor 32. The mounting end of the clamping assembly 4 is connected to the other end of the transmission shaft 31. The drive motor 32 drives the transmission shaft 31 to rotate, and the transmission shaft 31 drives the clamping assembly 4 to rotate.

[0033] Specifically, in some implementations, such as Figure 2 and 3 As shown, a positioning ring 33 is fixedly sleeved on the drive shaft 31, and a positioning protrusion 331 is protruding from the outer circumferential surface of the positioning ring 33. A proximity switch 34 is provided on the base 1, and the proximity switch 34 is correspondingly arranged with the positioning protrusion 331. Both the drive motor 32 and the proximity switch 34 are electrically connected to the control system. When the drive shaft 31 rotates, it drives the positioning ring 33 to rotate. When the positioning protrusion 331 moves away from the proximity switch 34, it can rotate normally. When the positioning protrusion 331 is located on the sensing surface of the proximity switch 34, the proximity switch 34 will send a feedback signal to the control system, which will then control the drive motor 32 to stop running, thereby allowing the drive shaft 31 to drive the clamping assembly 4 to rotate to a set angle. In some embodiments, the control system can be a PLC control system.

[0034] Specifically, in some implementations, such as Figure 2 and 3 As shown, a force sensor 35 is fitted onto the drive shaft 31, and a positioning element 36 is connected to the base 1. A positioning seat 311 is formed by a radial protrusion at one end of the drive shaft 31 near the clamping assembly 4. The force sensor 35 is located between the positioning seat 311 and the positioning element 36. One end of the force sensor 35 abuts against the positioning seat 311, and the other end abuts against the positioning element 36. The side of the positioning element 36 is fitted onto the outside of the drive shaft 31 but is not connected to it. The force sensor 35 is electrically connected to the control system. When the pressure-adjusting drive mechanism 2 compresses the three-way valve, the force sensor 35 can monitor the compressive force fed back from the positioning seat 311 and promptly feed the signal back to the control system to prevent excessive pressure that could damage the equipment or the three-way valve.

[0035] Specifically, in some implementations, such as Figure 2 and 3 As shown, a coupling 37 is provided between the drive shaft 31 and the drive motor 32. The output shaft of the drive motor 32 is connected to the input end of the coupling 37, and the end of the drive shaft 31 near the drive motor 32 is connected to the output end of the coupling 37.

[0036] Specifically, in some implementations, such as Figure 2 and 3 As shown, at least one first bearing 312 is sleeved on the drive shaft 31, and a bearing seat 11 is installed on the base 1, with the first bearing 312 disposed on the bearing seat 11.

[0037] In some of these implementations, such as Figure 2 and 3As shown, the limiting member 6 includes a rotating shaft 61 and a limiting seat 62. At least one second bearing 63 is sleeved on the rotating shaft 61. The second bearing 63 is mounted on the support member 5. A side radial protrusion of the rotating shaft 61 forms an isolation seat 611. The limiting seat 62 is sleeved on the end of the rotating shaft 61 away from the second bearing 63, and one end of the limiting seat 62 abuts against the isolation seat 611.

[0038] Obviously, this utility model is used to fix plastic parts to be welded during laser welding. Specifically, it is used for fixing plastic parts during laser welding of a three-way valve. The system includes a base, a flat pressure drive mechanism, a rotary drive mechanism, a clamping assembly, a support member, and a limiting member. Both the flat pressure drive mechanism and the rotary drive mechanism are connected to the base. The mounting end of the clamping assembly is driven by the rotary drive mechanism. One end of the support member is driven by the flat pressure drive mechanism. One end of the limiting member is rotatably connected to the support member. The limiting member corresponds to the clamping end of the clamping assembly. The flat pressure drive mechanism can be a three-axis telescopic cylinder, and one end of the support member is connected to the telescopic rod of the three-axis telescopic cylinder. The end connection allows the flat pressure drive mechanism to drive the limiting component to reciprocate in the X direction, while the rotary drive mechanism drives the clamping assembly to rotate, bringing one end of the plastic part into contact with the limiting component. The clamping assembly then clamps the other end of the plastic part. The flat pressure drive mechanism pushes the plastic part towards the clamping assembly, and the rotary drive mechanism drives the clamping assembly to rotate. The clamping assembly then rotates the plastic part, allowing the laser welding machine to weld around the joint of the plastic part while maintaining the position of the clamping assembly. This minimizes the displacement of the plastic part, making it easier to confirm the welding position and thus optimizing the clamping effect and improving welding efficiency.

[0039] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on the utility model are within the protection scope of the utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
