Description

Technical Field

[0001] This invention relates to the field of automated transfer mechanism technology, and more specifically to a brazing sheet transfer mechanism with cam-linked clamping function. Background Technology

[0002] In the processing of electronic devices, heat dissipation modules, metal connectors and precision hardware products, it is usually necessary to accurately transfer the solder pieces to the product surface and then press and weld them to achieve the functions of heat conduction, electrical conduction or structural connection.

[0003] Most existing solder transfer mechanisms use linear modules, cylinders, or multi-axis linkage robots for handling. While these mechanisms can achieve basic adsorption and transfer actions, they still have the following problems: First, the multi-axis linkage structure is complex to control, has poor motion synchronization, and is prone to motion interference, resulting in insufficient solder transfer accuracy. Second, existing structures lack a stable linkage clamping structure during solder attachment, which can cause solder to shift, lift, or become unstable, thus affecting the subsequent welding quality.

[0004] In addition, the existing rotating suction head structure is prone to cumulative angular deviation during long-term operation, which causes the suction head posture to shift, thereby affecting the repeatability and consistency of the brazing die.

[0005] Therefore, there is an urgent need to provide a cam-linked clamping mechanism for transferring brazing plates to solve the aforementioned problems in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a cam-linked clamping mechanism for transferring brazing chips, so as to solve the problems of complex motion control, poor stability of brazing chip transfer, and insufficient positioning accuracy in the prior art.

[0007] A cam-linked clamping mechanism for transferring brazed pieces includes a cam plate with cam grooves. A servo motor is mounted on the back of the cam plate, and a motor rod is connected to the shaft of the servo motor, driving the motor rod to rotate in both directions. A first sliding block is rotatably connected to the other end of the motor rod. The first sliding block reciprocates within the cam grooves driven by the servo motor. A first guide rail module is horizontally mounted on the cam plate. A second sliding block is slidably engaged with the first guide rail module. A vertically mounted second guide rail module is mounted on the second sliding block. The movement of the first sliding block drives the second sliding block to reciprocate along the first guide rail module. A suction component is mounted on the second guide rail module for suction and transfer of the brazed pieces.

[0008] Preferably, the second guide rail module is provided with a motor mounting plate; and a rotary motor is provided on the motor mounting plate; the rotating shaft of the rotary motor is connected to a suction head; and a clamping cylinder is also provided and mounted on the cam plate; the piston rod of the clamping cylinder is connected to a clamping block.

[0009] Preferably, the top of the rotary motor is provided with a rotary joint; and the rotary joint is connected to the suction head; and the rotary joint is provided with a light-shielding plate; and an optical coupler is provided on one side of the motor mounting plate; when the shaft of the rotary motor rotates, the rotary joint and the suction head rotate synchronously; when the light-shielding plate blocks the light from the optical coupler, the optical coupler outputs an origin detection signal to the control system to calibrate the rotation position of the rotary motor.

[0010] Preferably, the cam groove is semi-circular; and the two ends of the cam groove are distributed at right angles.

[0011] Preferably, the first sliding block slides along the trajectory direction of the cam groove to drive the second sliding block to move horizontally along the first guide rail module.

[0012] Preferably, the clamping block presses down and clamps the brazing die after the suction head completes the transfer of the brazing die.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting the cam slot, the first sliding block and the servo motor to form a cam drive structure, the preset trajectory movement of the suction component is realized, which reduces the complexity of multi-axis linkage control and improves motion synchronization and operation stability.

[0014] 2. By setting up the first guide rail module and the second guide rail module, the suction component can achieve linkage movement in the horizontal and vertical directions, thereby improving the motion accuracy and handling stability during the transfer of the solder piece.

[0015] 3. By setting up a rotary motor and suction head structure, the attitude adjustment during the transfer of the solder piece can be realized, thereby improving the accuracy of the solder piece attachment position.

[0016] 4. By setting up a clamping cylinder and clamping block, the brazing piece can be pressed down and clamped after the suction head completes the transfer of the brazing piece, thereby effectively preventing the brazing piece from shifting or lifting, improving the stability of subsequent welding and the product yield.

[0017] 5. By setting up a rotary joint, light shield, and optical coupler to form an origin detection structure, the rotation position of the rotary motor can be calibrated in real time, thereby effectively avoiding the cumulative angle error caused by long-term operation of the suction head, and improving repeatability and processing consistency.

[0018] 6. By setting the cam groove to a semi-circular arc and making the two ends of the cam groove perpendicular to each other, a preset motion trajectory and pause switching position are formed, which further improves the stability of the brazing blade transfer and clamping process.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that the terms "first," "second," etc., used in this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this disclosure.

[0026] Please see Figures 1-2In this embodiment of the invention, a cam plate transfer mechanism with cam linkage clamping function includes a cam plate 1, on which a cam groove 11 is formed.

[0027] A servo motor 2 is provided on the back of the cam plate 1. The shaft of the servo motor 2 is connected to a motor rod 21. The other end of the motor rod 21 is rotatably connected to a first sliding block 22. The first sliding block 22 is slidably disposed in the cam groove 11.

[0028] The servo motor 2 drives the motor rod 21 to rotate in both directions, thereby driving the first sliding block 22 to slide along the cam groove 11 and form a preset trajectory.

[0029] Furthermore, a first guide rail module 3 is horizontally provided on the cam plate 1, a second sliding block 31 is slidably provided on the first guide rail module 3, and a second guide rail module 4 is vertically provided on the second sliding block 31.

[0030] When the first sliding block 22 moves within the cam groove 11, it can drive the second sliding block 31 to move horizontally along the first guide rail module 3, thereby realizing the horizontal linkage movement of the suction component.

[0031] The second guide rail module 4 is equipped with a suction component for adsorbing and transferring the solder pieces.

[0032] Furthermore, the second guide rail module 4 is provided with a motor mounting plate 41, and a rotary motor 42 is provided on the motor mounting plate 41. The rotating shaft of the rotary motor 42 is connected to a suction head 43.

[0033] The rotary motor 42 can drive the suction head 43 to rotate, thereby realizing the angle adjustment during the transfer of the solder piece.

[0034] In addition, a clamping cylinder 6 is installed on the cam plate 1, and the piston rod of the clamping cylinder 6 is connected to a clamping block 61.

[0035] After the pick-up head 43 completes the transfer of the solder piece, the clamping cylinder 6 drives the clamping block 61 to press down and clamp the solder piece to improve the adhesion stability of the solder piece.

[0036] Furthermore, the top of the rotary motor 42 is provided with a rotary joint 7, which is connected to the suction head 43, and a light shield 71 is provided on the rotary joint 7. An optical coupler 72 is provided on one side of the motor mounting plate 41.

[0037] When the rotary motor 42 drives the suction head 43 to rotate, the rotary joint 7 and the light shield 71 rotate synchronously. When the light shield 71 blocks the light from the optocoupler 72, the optocoupler 72 outputs the origin detection signal to the control system to calibrate the rotation position of the rotary motor 42, thereby avoiding the cumulative angle error of the suction head 43 during long-term operation.

[0038] Preferably, the cam groove 11 is semi-circular, and the two ends of the cam groove 11 are distributed at right angles, so that the suction component forms a preset transfer trajectory and forms a corresponding pause switching position, thereby improving the stability of the electrode adsorption, transfer and pressing process.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
