Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and more specifically to a drive control device for a press-fitting machine. Background Technology

[0002] In modern industrial production, press fitting machines serve as core precision assembly equipment in fields such as electronic equipment manufacturing and machining. Their operational accuracy, adaptability, and stability directly determine the product assembly quality and production efficiency. As industrial products become more complex, smaller, and more precise, the application of irregularly shaped workpieces is becoming increasingly widespread. The limitations of traditional press fitting machines and related technical solutions are becoming more and more prominent, making it difficult to meet actual production needs.

[0003] The press-fitting machine disclosed in patent application CN107160153A focuses on the press-fitting and positioning of specific workpieces. This press-fitting machine includes an upper beam and a base connected by guide columns. A press-fitting slide is provided between the upper beam and the base, which slides and engages with the guide columns. A hydraulic press is mounted on the upper beam, and the piston rod of the hydraulic press is connected to the press-fitting slide. A positioning fixture is installed on the base. The press-fitting slide has a large worktable surface. Driven by the hydraulic press, it slides down along the guide columns, providing uniform pressing force. It can press-fit workpieces with large end face contours in one go, ensuring reliable pressing quality and high production efficiency.

[0004] In the aforementioned patent, for lateral assembly points of irregularly shaped workpieces, vertical angle pressing cannot accurately align the assembly position, which can easily lead to misalignment, uneven pressure distribution, and other problems, resulting in incomplete assembly or damage to parts. In production, manual secondary adjustments are often required, which can easily introduce human error.

[0005] The conventional hydraulic drive system relied upon by the press-fitting machine in the aforementioned patent lacks a flexible transition mechanism and cannot effectively absorb the instantaneous kinetic energy during state switching. When switching between operating states, there is a significant risk of impact. When the press-fitting head switches from a fast feed state to a slow press-fitting state, due to the lack of an effective buffer transition mechanism, the instantaneous impact force caused by the sudden change in kinetic energy will not only cause continuous damage to the mechanical structure of the press-fitting head, accelerate component wear, and shorten the service life of the equipment, but also cause hidden damage to precision electronic components, affecting the reliability of the product.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0036] Please see Figure 1 - Figure 11This invention provides a drive control device for press fitting connections using a press fitting machine. The device includes a workbench 1 and a frame 2. A control unit 3 is mounted on the frame 2, an angle adjustment unit 4 is mounted on the control unit 3, a press fitting unit 5 is mounted on the angle adjustment unit 4, a compensation unit 6 is mounted on the press fitting unit 5, and a support unit 7 is mounted on the angle adjustment unit 4. The press fitting unit 5 achieves stable press fitting and pressure protection. It includes a positioning plate 51, a cylinder 52 is fixedly connected to the positioning plate 51, and a press fitting head 53 is slidably connected to one end of the cylinder 52. The press fitting head 53 is pushed by the gas pressure inside the cylinder 52 to perform the press fitting action. A piston plate 54 is fixedly connected to one end of the press fitting head 53 and is slidably disposed inside the cylinder 52. A tension spring 55 is elastically connected between cylinder 54 and the inner wall of cylinder 52. A press plate 56 is detachably connected to cylinder 52. The other end of press head 53 slides through press plate 56. An exhaust pipe 57 is connected to cylinder 52. A rotary joint 58 is installed at the end of exhaust pipe 57. A one-way intake valve 59 is connected to cylinder 52 to ensure gas supply. An electrically controlled pressure relief valve 2W025-08 is installed on cylinder 52. It has a small diameter design and controllable pressure relief speed. When the gas pressure inside cylinder 52 exceeds the threshold, it quickly relieves pressure to protect electronic components from overpressure damage. The electrically controlled pressure relief valve is set opposite to exhaust pipe 57 and uses tension spring 55 and electrically controlled pressure relief valve to buffer impact.

[0037] In this invention, the control unit 3, as the core control unit of the equipment, receives process parameter commands, including a hydraulic cylinder 31. This cylinder is a MOB-16×25-S, a miniature cylinder design, allowing for precise control of the feed speed and avoiding impact on electronic components. It is adapted to the short-stroke feed requirements of the press-fit head 53. The hydraulic cylinder 31 is mounted on the frame 2. A mounting column 32 is connected to the movable end of the hydraulic cylinder 31. A cover 33 is installed on the outer wall of the mounting column 32. A rotary motor 34, using a stepper motor 28HS24-1004, is mounted on the cover 33. S, low torque output, combined with gear transmission, can achieve fine adjustment of pressing angle, adapting to the side pressing angle requirements of irregular electronic components. The output shaft of the rotary motor 34 is equipped with gear 35, and the bottom of the mounting column 32 is rotatably connected to the rotating shaft 36. Gear 37 is sleeved on the rotating shaft 36. Gear 35 and gear 37 are both located inside the machine cover 33 and mesh with each other. The pressing part 5 is fed up and down through the hydraulic cylinder 31. The rotating motor 34 and gear transmission drive the angle adjustment part 4 to rotate, providing power for pressing angle and position adjustment.

[0038] In this embodiment, the angle adjustment part 4 has a preset pressing angle and includes a guide post 41. The guide post 41 is fixedly connected to the rotating shaft 36. The bottom sides of the guide post 41 are symmetrically provided with mounting grooves 42. Each mounting groove 42 has a wire hole 43. Each mounting groove 42 is equipped with an electric push rod 44. The miniature electric push rod TJC-10-20 is used to push flexibly to avoid deformation of the positioning plate 51 and protect the alignment accuracy between the pressing head 53 and the electronic components. The movable end of each electric push rod 44 is connected to a ball pad. Ball pads 46 are symmetrically installed on the bottom two sides of the guide post 41. Hinges are fixedly connected to both the positioning plate 51 and the guide post 41. The positioning plate 51 and the guide post 41 are hinged together by the hinges. Ball pads 45 and 46 abut against each other. The positioning plate 51 is rotated by the extension and retraction of the electric push rod 44. The multi-angle adjustment of the pressing head 53 is achieved with the hinge structure to meet the angle requirements of lateral pressing of irregular workpieces.

[0039] Furthermore, the compensation unit 6 provides a stable power source for the pressing head 53 and also assists in buffering pressure impacts. It includes a mounting plate 61, on which a positioning shaft 62 is rotatably connected. An angle sensor 63 (a miniature angle sensor WDD35D4) is mounted on the positioning shaft 62. A U-shaped plate 64 is fixedly connected to the positioning shaft 62. A cylinder 65 is installed between the ears of the U-shaped plate 64. A push plate 66 is fixedly connected to the piston rod end of cylinder 65. An air inlet pipe 67 is slidably connected to the inner wall of cylinder 65. A cylinder 68 is installed on one ear of the U-shaped plate 64. Both cylinders 65 and 68 are miniature cylinders (CDJ2B10x10-B), featuring a lightweight design, low thrust output, and suitability for low-flow gas replenishment needs. A pressure plate 69 is fixedly connected to the piston rod end of cylinder 68. A groove is formed on the other ear of the U-shaped plate 64, with a rotatable connection between the inner walls of the groove. The rotating plate 610 and cylinder 2 68 are connected to a compensation pipe 611 at their bottom ends. A suction pipe 612 is connected to the side wall of cylinder 2 68, and a one-way intake valve 2 is installed on the suction pipe 612. A mounting plate 61 is installed on the outer wall of the guide post 41. A spring 1 is fitted onto the piston rod of cylinder 1 65, elastically connecting the piston to the inner wall of cylinder 1 65. A spring 2 is fitted onto the piston rod of cylinder 2 68, elastically connecting the outer wall of cylinder 2 68. Between the pressure plate 69 and the rotating plate 610, a torsion spring is elastically connected to the inner wall of the groove. One end of the rotating plate 610 contacts the push plate 66. The air inlet pipe 67 has an L-shaped structure and one end of the air inlet pipe 67 is rotatably connected to the rotary joint 58. The compensation pipe 611 is made of rubber and is connected to the one-way air inlet valve 59. Gas suction and replenishment are completed through the air extraction pipe 612 and the compensation pipe 611 to balance the pressure fluctuation in the cylinder 52. The spring structure is used to realize reciprocating air injection.

[0040] It is worth noting that the support part 7 receives the signal from the angle sensor 63, transforming the flexible hinged connection into a rigid support, reducing component fatigue wear. It includes two rod grooves 71, which are symmetrically opened on both sides of the guide post 41. The guide post 41 also has sliding grooves 72 on both sides. Each rod groove 71 is equipped with an electric push rod 73, which is a small electric push rod TJC-8-15 with small and controllable thrust. When pushing the support plate 74, it can slowly fit against the positioning plate 51, avoiding rigid impact that could cause the positioning plate 51 to shift, thus ensuring press-fit stability. The movable end of each electric push rod 73 is equipped with a support plate 74. Each support plate 74 has an L-shaped structure and an inclined inner wall. The support plates 74 are slidably set on the inner wall of the sliding groove 72 on the same side. The electric push rod 73 pushes the support plate 74 to abut against the positioning plate 51, preventing the positioning plate 51 from shifting or shaking during press-fit. Each electric push rod 73 is electrically connected to the angle sensor 63.

[0041] It is worth noting that the workbench 1 is equipped with a control cabinet 8, a control panel 9, a dual-axis displacement slide 10 (using a micro electric slide XY-60-100 for high-precision displacement control, adaptable to the small-range displacement requirements of micro-electronic components), and a loading platform 11. The control cabinet 8 serves as the core control unit, analyzing process parameters, driving the various execution components to work collaboratively, and simultaneously collecting equipment operating status signals to form a closed-loop control. The control cabinet 8 contains a central processing unit and a power module. The control panel 9 serves as the human-machine interface. The process parameters input by the operator are transmitted to the central processing unit via an RS485 bus. After analyzing the parameters, the central processing unit converts the control signals into electrical signals that the equipment can recognize through the drive module, and transmits them to each execution device via a dedicated line. At the same time, the operating status signals of each device are fed back to the central processing unit through the signal acquisition module, forming a closed-loop control. The control cabinet 8, control panel 9, and dual-axis displacement slide 10 are all installed on the workbench 1, and the loading platform 11 is installed on the moving end of the dual-axis displacement slide 10.

[0042] Working principle: Electronic components to be assembled are precisely fixed onto the loading platform 11 on the workbench 1 using a special fixture to ensure component positioning accuracy. The operator inputs pressing process parameters, including pressing angle, pressure threshold, feed speed, and pressing stroke, through the control panel 9. The parameter signals are transmitted in real time to the central processing unit in the control cabinet 8. The power module in the control cabinet 8 starts synchronously, powering the hydraulic cylinder 31, rotary motor 34, electric push rod 1 44, electrically controlled pressure relief valve, angle sensor 63, and electric push rod 2. Power is supplied to the electrical equipment such as 73 and the dual-axis displacement slide 10. The pressure plate 69 is manually pressed to draw in external air through the air extraction pipe 612 and to fill the space between the inner wall of the cylinder 52 and the piston plate 54 through the compensation pipe 611. The reciprocating air injection motion, in cooperation with the second spring, provides a power source for the pressing head 53. The gas in the cylinder 52 enters the cylinder 65 through the air outlet pipe 57, the rotary joint 58, and the air inlet pipe 67 for further filling, thereby squeezing the push plate 66 on the piston rod to abut against the rotating plate 610, completing the preparation before pressing.

[0043] According to preset parameters, the central processing unit first controls the moving end of the dual-axis displacement slide 10 to drive the loading table 11 to move, so as to achieve precise positioning of the workpiece in the X / Y axis direction and ensure that the pressing target point corresponds to the initial position of the pressing head 53.

[0044] According to the preset pressing angle, the central processing unit sends extension and retraction commands to the two electric push rods 44 respectively. The electric push rods 44 drive the ball pad 45 to rise or fall through the extension and retraction action, thereby pushing the positioning plate 51 to rotate angularly around the hinge point. The rotary motor 34 drives the guide column 41 to rotate through the meshing of gear 35 and gear 37, thereby driving the rotating shaft 36 to rotate, which in turn drives the positioning plate 51 to rotate, adjusting the pressing head 53 to the preset pressing angle. When the cylinder 52 follows the angular rotation, it drives the air inlet pipe 67 to rotate through the rotary joint 58 and moves along the inner wall of the cylinder 65. At the same time, the cylinder 65 is subjected to force and rotates angularly around the positioning shaft 62. The angle sensor 63 generates an angular offset signal to meet the lateral pressing requirements of irregular workpieces.

[0045] After the angle is adjusted to the correct position, the central processing unit controls the movable end of the hydraulic cylinder 31 to push the mounting column 32 downward, driving the pressing head 53 to feed towards the workpiece. After the pressing head 53 contacts the workpiece, it generates a pressing force. The workpiece generates a reaction force on the pressing head 53, causing the pressing head 53 to drive the piston plate 54 to slide into the cylinder 52 and stretch the tension spring 55. The sliding of the piston plate 54 compresses the gas in the cylinder 52, forming a preliminary buffer. The gas enters the first cylinder 65, pushing the piston and piston rod in the first cylinder 65 to extend out of the first cylinder 65. The push plate 66 pushes the rotating plate 610 to rotate, and the compression plate 69 contracts into the second cylinder 68, causing the piston in the second cylinder 68 to compress the gas. The gas is replenished into the cylinder 52 through the compensation pipe 611 and the one-way air inlet valve 59, balancing the pressure fluctuations in the cylinder 52 and achieving a pressure holding effect.

[0046] Angle sensor 63 sends an angular offset signal to the central processing unit of control cabinet 8, thereby controlling the extension of the movable end of electric push rod 73 on the corresponding side, which in turn pushes the support plate 74 downward. The inclined inner wall of the support plate 74 adapts to the edge of the rotated positioning disk 51 and abuts against it, transforming the flexible hinged connection into a rigid connection with supporting force. This reduces the metal fatigue wear of the hinged plate during pressing. The ball pads 45 and 46 provide limiting support for the positioning disk 51, further buffering the reaction force during pressing, preventing the positioning disk 51 from misaligning and shaking, and extending its service life.

[0047] After pressing is completed, all components are reset. The movable end of the hydraulic cylinder 31 drives the mounting column 32 to rise, and the pressing head 53 moves away from the workpiece. The electric push rod 44 resets and pushes the positioning plate 51 to the initial angle perpendicular to the loading table 11. The tension spring 55 releases its elastic force to pull the piston plate 54 to reset, causing the pressing head 53 to pop out. The piston rod of the cylinder 65 is reset and retracted by the spring. The rotating plate 610 is reset under the torsion of the torsion spring and contacts the push plate 66 and moves away from the pressing plate 69. The piston rod of the cylinder 68 is reset and extended by the spring. External air is drawn back into the cylinder 68 through the air extraction pipe 612 and the one-way air inlet valve 2 to prepare for the next pressing. When the air pressure in the cylinder 52 exceeds the safety threshold, the electric pressure relief valve opens to actively relieve pressure.

[0048] In the above work, the electric actuator 44 and electric actuator 73 can also be replaced by hydraulic telescopic cylinders to achieve the same effect. Similarly, the cylinders 65 and 68 in the compensation unit 6 can also be hydraulic telescopic cylinders that conform to the standards of this field, replacing the air pressure with hydraulic pressure for drive compensation, pressurization and buffering effects.
