[0014] The present invention has the following beneficial effects: 1. The gripping spring assembly of the present invention includes a second finger gripper, a first suction rod, a pressure rod, and a spring pressure rod. When installing the spring, it plays multiple roles such as gripping, pre-pressing, and fixing. With the lateral pushing of the spring assembly, it can complete the installation of complex spring structures. It eliminates the need for multiple machines and multiple sites for production, significantly reducing equipment and manufacturing costs. The entire assembly machine has a high degree of automation, and production efficiency and yield can be greatly improved.

[0015] 2. The tooling assembly of the present invention is provided with a rocker-type first insert. Under the action of the spring restoring force, the pressure head of the first insert can press down the assembled moving spring and pin, avoiding misalignment of the moving spring and pin before welding, and improving the assembly accuracy of the moving spring terminal. Through the pressing of the pressing assembly, the first insert can be lifted up and provide working space for the installation of the moving spring and pin. At the same time, the U-shaped pressing rod and the spring pressing rod make way for the movement of the first insert. The structure of the first insert is simple and ingenious, making the operation of the pressing assembly simple and simplifying the structure of the equipment.

[0016] 3. The U-shaped pressure block of the clamping assembly of the present invention provides a moving space for the first insert. When the moving spring and the pin are assembled, the pressure block can fix the terminal and prevent the terminal from moving and misaligning, thus effectively ensuring the assembly accuracy.

[0017] 4. The first sensor of the present invention can identify the transmitted moving spring in a timely manner and feed the information back to the controller. Under the control of the controller, the material blocking assembly can perform blocking operations on time, with a high degree of automation. At the same time, under the control of the controller, the top rod can fix the next moving spring when the stop block is lifted, so that the moving springs can be fed one by one, and the production cycle is effectively guaranteed.

[0018] 5. The moving spring switching assembly of the present invention can remove the moving spring from the first conveying channel and rotate it to the required feeding angle, ensuring that the moving spring can be accurately grasped by the moving spring gripping assembly. The moving spring switching assembly has a simple structure and can complete complex material picking and flipping actions through the joint control of a motor and multiple cylinders, with high reliability. 6. The spring mounting assembly of the present invention provides a lateral thrust for the installation of the spring, allowing the spring to be inserted into the terminal; the end of the push rod of the spring mounting assembly is set in a figure-eight shape, which can fit the shape of the spring, making the assembly and movement of the spring more precise; the spring pressure rod of the spring gripping assembly provides a certain pressure for fixing the spring, at which time the second finger clamp and the first suction rod can move apart, providing movement space for the push rod to push, and the cooperation between the mechanisms is smooth and efficient.

[0019] 7. The structure of the baffle seat of the present invention is simple. The pin can be quickly fixed by the extension and retraction of the baffle rod, which can prevent the next pin from moving forward when the pin is being picked up. The second sensor can sense the pin in time, so that the equipment can be accurately controlled automatically.

[0020] 8. The pin rotation mechanism of the present invention is provided with a first limiting block. The sliding groove on the first limiting block can accurately connect to the pin conveyed by the second conveying channel, ensuring that the pin is fixed in position when gripping. A U-shaped rotating block is provided in the U-shaped groove of the first limiting block. The U-shaped first limiting block can make reasonable use of its internal space, reduce the space occupied by the mechanism, and facilitate the miniaturization design of the equipment. By moving the rotating block, the rotation angle of the pin can be changed, which facilitates the gripping of the pin gripping mechanism. The U-shaped rotating block can avoid the third finger gripper. The mechanism is compact and does not interfere with each other.

[0021] 9. When installing the moving spring and the pin, the present invention provides a limiting mechanism at the assembly position. The second limiting block of the limiting mechanism can fit into the limiting groove of the base, which can fix the tooling components and prevent the tooling components from moving or misaligning, thus effectively ensuring the assembly accuracy.

[0022] 10. The material gripping assembly of the present invention can not only feed the base of the terminal, but also rotate the base so that the base can feed the terminal onto the tooling assembly at the required position and angle without the need for multiple moving operations, and can adapt to different feeding mechanisms.

A controller 3 is housed within the frame 1, and sensors, motors, and cylinders within the machine are electrically connected to the controller 3. In this embodiment, the moving spring terminal uses a U-shaped moving spring and matching pins. The moving spring is inserted into the base of the terminal from the side, and finally, the pins are assembled. This invention is not limited to the moving spring terminal of this embodiment. Multiple tooling assemblies 4 are slidably mounted on the main slide rail 2. Each tooling assembly 4 includes a base 5 and a rocker-type first insert 6 mounted on the base 5. A moving spring mounting assembly 7 and a pin mounting assembly 8 are mounted above the main slide rail 2. A moving spring feeding assembly 9 is located on one side of the moving spring mounting assembly 7, and a pin feeding assembly 9 is located on one side of the pin mounting assembly 8. Component 10; The moving spring assembly 7 includes a movable push rod 11 inclined above the main slide rail 2, which provides lateral thrust for the installation of the moving spring, allowing the moving spring to be inserted laterally into the terminal; a clamping assembly 12 is provided on the opposite side of the push rod 11, and a gripping spring assembly 13 is provided above the push rod 11; a feeding assembly 14 is provided on the side of the main slide rail 2 near the starting end, and a tooling feeding assembly 15 parallel to it is provided on one side of the main slide rail 2; considering the handling and assembly time of the moving spring and the pin, in order to meet the continuous production cycle, the moving spring assembly 7 and the pin assembly 8, as well as the corresponding moving spring feeding assembly 9, pin feeding assembly 10, clamping assembly 12 and gripping spring assembly 13, are preferably in two sets.

[0027] Furthermore, the base 5 has a through hole 16 in the middle. During production, the through hole 16 facilitates the placement and removal of terminals, and dust falling during production can be discharged through the through hole 16 without accumulating and causing pollution. The tooling assembly 4 has a second insert 17 hinged to the first insert 6 on one side of the through hole 16. A spring 18 is provided on the hinged shaft. Under the restoring force of the spring 18, the first insert 6 can press down the assembled moving spring and pin, preventing the moving spring and pin from being misaligned before welding, and improving the assembly accuracy of the moving spring terminal. The first insert 6 includes a pressing head 19 for pressing the terminal and a connecting block 20 on the side away from the pressing head 19. The pressing head 19 and the connecting block 20 form the two ends of a rocker. The base 5 has a third insert 21 on the side of the through hole 16 away from the second insert 17, and one end of the moving spring abuts against the third insert 21.

[0028] Furthermore, the moving spring feeding assembly 9 includes a linear vibrator 22 and a first conveying channel 23 connected to the linear vibrator 22. The discharge end of the first conveying channel 23 points towards the main slide 2. A linear vibrating material plate 24 is provided on the side of the first conveying channel 23 away from the main slide 2. The moving spring is first vibrated by the linear vibrating material plate 24 and moves upward from the hopper, and then moves laterally within the first conveying channel 23 to one side of the main slide 2. A baffle assembly 25 is provided at the end of the first conveying channel 23 near the main slide 2. The baffle assembly 25 includes a stop block 26 and a first cylinder 27 that controls the lifting and lowering of the stop block 26. A first sensor 28 is provided on the side of the stop block 26 away from the main slide 2. A push rod 29 is provided on the side of the first sensor 28 away from the stop block 26. The push rod 29 is controlled to extend and retract by the second cylinder 30. The horizontal distance between the push rod 29 and the stop block 26 is the width of one moving spring. When the moving spring is being fed, the push rod 29, under the control of the controller 3, can fix the next moving spring when the stop block 26 is lifted, so that the moving springs can be fed one by one, and the production cycle is effectively guaranteed. The first cylinder 27, the second cylinder 30 and the first sensor 28 are electrically connected to the controller 3. The first sensor 28 is preferably a reflective photoelectric sensor, which can identify the moving springs transmitted in time and feed the information back to the controller 3. Under the control of the controller 3, the material blocking assembly 25 can perform blocking operations on time.

[0029] Furthermore, considering that the structure of the moving spring is generally non-flat or right-angled, when it is conveyed in the first conveying channel 23, the moving spring mostly moves laterally at a certain angle. The end of the moving spring feeding assembly 9 is provided with a moving spring switching assembly 31 for rotating the moving spring. The moving spring switching assembly 31 includes a first finger clamp 32 and a third cylinder 33 for controlling the gripping of the first finger clamp 32.

The first motor 34 is preferably a servo motor, which can accurately control the rotation angle so that the third cylinder 33 and the first finger clamp 32 connected to the third cylinder 33 rotate together. The first motor 34 is fixed on the first moving plate 35. One end of the first moving plate 35 is connected to a fourth cylinder 36. Under the push of the fourth cylinder 36, the first moving plate 35 can move horizontally perpendicular to the main slide 2. The moving spring switching assembly 31 can take the moving spring out of the first conveying channel 23 and rotate it to the required feeding angle to ensure that the moving spring can be accurately gripped by the moving spring gripping assembly 13.

[0031] Furthermore, the spring assembly 7 includes a bracket 51 mounted on the main slide rail 2 and a tenth cylinder 52 fixed on the bracket 51. The shaft extension end of the tenth cylinder 52 is connected to the push rod 11, and the push rod 11 is controlled by the tenth cylinder 52 to laterally push the spring. The width of the push rod 11 is smaller than the gripping width of the second finger clamp 37, and the end of the push rod 11 is preferably V-shaped to fit the shape of the spring, making the assembly and movement of the spring more precise. The clamping assembly 12 includes a pressure block 53 with a horizontal projection of U-shape. The width of the U-shaped groove of 3 is greater than that of the first insert 6. The U-shaped pressure block 53 provides moving space for the first insert 6. When the moving spring is assembled, the pressure block 53 can fix the terminal and prevent the terminal from moving and misaligning. The pressure block 53 is fixed on the first moving block 54. The main slide 2 is provided with a guide rail bracket 55. The guide rail bracket 55 is provided with an eleventh cylinder 56 that controls the up and down movement of the first moving block 54. When it is necessary to press the terminal, the eleventh cylinder 56 controls the first moving block 54 to move down, and the pressure block 53 presses and fixes the terminal.

[0032] Furthermore, the lead loading assembly 8 is located on the side of the spring loading assembly 7 away from the feeding assembly 14. The lead loading assembly 10 includes a linear vibrator 22 and a second conveying channel 57 connected to the linear vibrator 22.

[0037] Working principle of the invention: First, tooling assembly 4 is transported to tooling feeding assembly 15. When tooling assembly 4 is driven on tooling feeding assembly 15, it will first pass through demagnetizer assembly 107 and then be conveyed to first push tooling assembly 109. The ejector rod 110 of first push tooling assembly 109 will push tooling assembly 4 to transition slide assembly 108 and then convey it to the starting end of main slide 2 via transition slide assembly 108. Finally, it is pushed onto the conveyor belt of main slide 2 by second push tooling assembly 113.

[0038] When conveying on the main slide 2, the tooling assembly 4 first moves to the feeding assembly 14. At this time, the tooling assembly 4 is limited by the limiting mechanism 81, and the base of the terminal is transported by the gripping assembly 90. First, the second pressing assembly 91 presses and lifts the first insert 6, and the fourth finger clamp 92 clamps the base and places it on the tooling assembly 4. The synchronous extrusion block 94 presses and fixes the base on the tooling assembly 4. Then, the second pressing assembly 91 lifts back upward, and the base is pressed and fixed by the first insert 6.

[0039] Next, tooling assembly 4 moves to the spring assembly 7, at which point tooling assembly 4 is limited by limiting mechanism 81; the spring to be assembled is transported to the side of main slide 2 by spring feeding assembly 9, then rotated by spring switching assembly 31 at a certain angle, and transported above tooling assembly 4 by spring gripping assembly 13; the first pressing assembly 85 presses and lifts the first insert 6, the second finger gripper 37 picks up the spring and places it on one side of tooling assembly 4, and the first suction rod 38 simultaneously... The spring is attracted to the base, and the spring rod 44 presses one end of the spring onto the base. Then the spring mounting assembly 7 pushes the spring into the top of the base, and then the pressure rod 42 presses down to fix the spring. After the spring is fixed by the pressure rod 42, the spring mounting assembly 7 retracts first, the second finger clamp 37 releases its grip on the spring, and at the same time the first suction rod 38 breaks the vacuum and lifts upward. Then the first pressing assembly 85 is removed, the pressure head of the first insert 6 presses the spring to fix it, and finally the pressure rod 42 is lifted up and moved away.

[0040] Next, tooling assembly 4 moves to pin assembly 8, at which point tooling assembly 4 is limited by limiting mechanism 81; the pin to be assembled is transported to the side of main slide 2 by pin feeding assembly 10, and then transported to the top of tooling assembly 4 by pin gripping mechanism 65; first pressing assembly 85 presses and lifts first insert 6, second suction rod 76 adsorbs the pin and assembles it onto the base; then first pressing assembly 85 is removed, the pin is pressed and fixed by first insert 6, and finally tooling assembly 4 moves to the next process with the assembled moving spring and pin terminal.
