Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an apparatus for assembling pins and springs. Background Technology

[0002] Connectors formed by assembling pins and springs can be used in electronic products such as mobile phones, communications, automobiles, medical devices, and aerospace products for connection purposes. The assembly of pins and springs is a precision connection. During assembly, the spring needs to be fitted onto the pin and pressed together. During this pressing process, the integrity and stability of the product's appearance must be ensured, preventing wear and damage to the pins and plating, and ensuring the successful completion of a series of pin tests (such as impedance testing). Currently, it is usually done manually using tooling to fit the spring onto the pin and press it together. This is not only inefficient and costly, but also prone to scratching the product's appearance during manual pressing, failing to guarantee the integrity and stability of the product's appearance and affecting product quality. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a device for assembling PIN pins and springs.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a device for assembling PIN pins and springs, comprising a conveying mechanism, a PIN pin feeding mechanism, a spring feeding mechanism, a pressing mechanism, a first fixture, and a fixedly disposed second fixture. The conveying mechanism is disposed between the PIN pin feeding mechanism and the pressing mechanism and is used to convey the first fixture between the PIN pin feeding mechanism and the pressing mechanism. The PIN pin feeding mechanism is used to insert PIN pins into a first receiving groove on the first fixture. The spring feeding mechanism is disposed on the periphery of the second fixture to realize the insertion of springs into a second receiving groove on the second fixture. The pressing mechanism is disposed on the periphery of the second fixture and is used to clamp the springs on the second fixture, and also to sleeve the springs onto the PIN pins on the first fixture and press the springs and PIN pins together.

[0005] In a preferred embodiment, the conveying mechanism includes two sets of conveying components arranged side by side. Each set of conveying components includes a fixed guide rail and a base slidably disposed on the guide rail. At least one first fixture is provided on each of the two bases. The two bases slide along the corresponding guide rails under the drive of the same driving device, or the two bases slide along the corresponding guide rails under the drive of different driving devices.

[0006] In a preferred embodiment, the driving device includes a first motor and an annular conveyor belt that is drivenly connected to the output shaft of the first motor. The annular conveyor belt is drivenly connected to the two bases respectively to drive the two bases to slide.

[0007] Alternatively, the driving device includes a first motor and an annular transmission chain drivenly connected to the output shaft of the first motor, the annular transmission chain being drivenly connected to the two bases respectively to drive the two bases to slide.

[0008] In a preferred embodiment, the conveying assembly further includes a mounting seat slidably disposed on the base and a first elastic member disposed between the mounting seat and the base. The first fixture is disposed on the mounting seat. The mounting seat can slide relative to the base between a first position and a second position, and can be reset from the second position to the first position under the action of the first elastic member. A partition is fixedly disposed between the two guide rails. The two ends of the partition along the length direction of the guide rails are respectively provided with guide slopes corresponding to the two mounting seats. The two mounting seats can slide from the first position to the second position under the action of the guide slopes to make way for each other.

[0009] In a preferred embodiment, the pressing mechanism includes a first gripper mechanism, a first horizontal drive mechanism for driving the first gripper mechanism to move horizontally between the first fixture and the second fixture, and a first vertical drive mechanism for driving the first gripper mechanism to move up and down reciprocally. The first gripper mechanism includes at least two first grippers for gripping the spring and a first gripper drive mechanism connected to the first grippers to drive the first grippers to open and close.

[0010] In a preferred embodiment, the first gripper mechanism further includes a guide sleeve disposed between each of the first grippers and having an open bottom. The sidewall of the guide sleeve is provided with a first clearance notch corresponding to each of the first grippers. The inner diameter of the guide sleeve is larger than the outer diameter of the upper end of the second fixture. The first grippers can be inserted into the guide sleeve through the first clearance notch to grip the spring.

[0011] In a preferred embodiment, the first gripper mechanism further includes a guide seat disposed on the top of the guide sleeve, a guide pin slidably disposed on the guide seat and extending into the guide sleeve, and a second elastic element for sliding the guide pin downward to reset; when the pressing mechanism grips the spring on the second fixture, the guide pin is inserted into the spring; when the pressing mechanism sleeves the spring on the PIN pin on the first fixture and presses the spring and the PIN pin together, the guide pin can overcome the elastic force of the second elastic element and move upward to make way under the pushing action of the PIN pin.

[0012] In a preferred embodiment, the device further includes a feeding mechanism, which includes a material container and a feeding gripper mechanism for clamping the pressed spring and PIN pin. The first up-down driving mechanism is also used to drive the feeding gripper mechanism to move up and down reciprocally, and the first horizontal driving mechanism is also used to drive the feeding gripper mechanism to move horizontally between the top of the first fixture and the top of the material container.

[0013] In a preferred embodiment, the PIN feeding mechanism includes a second gripper mechanism for gripping the PIN, a tray on which a plurality of PINs are placed, a second horizontal drive mechanism for driving the second gripper mechanism to move horizontally between the tray and the first fixture, and a second vertical drive mechanism for driving the second gripper mechanism to move up and down reciprocally.

[0014] In a preferred embodiment, the spring feeding mechanism includes a vibratory feeder, a third gripper mechanism for gripping the spring, a feeding track connected to the outlet of the vibratory feeder, a third horizontal drive mechanism for driving the third gripper mechanism to move horizontally between the end of the feeding track and the second fixture, a third vertical drive mechanism for driving the third gripper mechanism to move up and down reciprocally, and a rotary drive mechanism for driving the third gripper mechanism to rotate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides an apparatus for assembling PIN pins and springs. A PIN pin feeding mechanism inserts PIN pins into a first receiving groove on a first fixture. A conveying mechanism transports the first fixture between the PIN pin feeding mechanism and a pressing mechanism. A spring feeding mechanism inserts a spring into a second receiving groove on a second fixture. The pressing mechanism then clamps the spring on the second fixture and places it onto the PIN pin on the first fixture located at the pressing mechanism, pressing the spring and PIN pin together. This achieves automatic assembly of the spring and PIN pin, improving assembly efficiency, reducing labor costs, and minimizing scratches caused by manual labor, ensuring the product's appearance integrity and stability, and avoiding waste.

[0017] 2. The present invention uses two sets of conveying components to convey different first fixtures respectively, so that when the pressing mechanism presses the PIN pin in the first fixture on one set of conveying components with the spring, the PIN pin feeding mechanism can feed the PIN pin to the first fixture on the other set of conveying components, which can greatly improve the assembly efficiency.

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the apparatus of the present invention for assembling PIN pins and springs is not limited to the embodiments.

[0036] For an example, please refer to [link / reference]. Figures 1 to 15As shown, this embodiment of an apparatus for assembling PIN pins and springs includes a frame 1, a conveying mechanism 2, a PIN pin feeding mechanism 3, a spring feeding mechanism 4, a pressing mechanism 5, a first fixture 7, and a second fixture 8 fixedly mounted on the frame 1. The conveying mechanism 2, PIN pin feeding mechanism 3, spring feeding mechanism 4, and pressing mechanism 5 are all mounted on the frame 1. The first fixture 7 has a first receiving groove 71 with an upward opening, and the second fixture 8 has a second receiving groove (not shown in the figure) with an upward opening. The conveying mechanism 2 is located between the PIN pin feeding mechanism 3 and the pressing mechanism 5, and the conveying mechanism 2 is used to place the first fixture 7 on the PIN pin... The feeding mechanism 3 and the pressing mechanism 5 are connected for conveying; the PIN feeding mechanism 3 is used to insert the PIN pin 10 into the first receiving groove 71 on the first fixture 7 located at the PIN feeding mechanism 3; the spring feeding mechanism 4 is disposed on the periphery of the second fixture 8 to realize the insertion of the spring 20 into the second receiving groove on the second fixture 8; the pressing mechanism 5 is disposed on the periphery of the second fixture 8, and the pressing mechanism 5 is used to clamp the spring 20 on the second fixture 8. The pressing mechanism 5 is also used to sleeve the clamped spring 20 on the PIN pin 10 located on the first fixture 7 located at the pressing mechanism 5 and press the spring 20 and the PIN pin 10 together to form a connector.

[0037] In this embodiment, the PIN needle 10 is inserted into the first receiving groove 71 on the first fixture 7 by the PIN needle feeding mechanism 3. The conveying mechanism 2 transports the first fixture 7 between the PIN needle feeding mechanism 3 and the pressing mechanism 5. The spring 20 is inserted into the second receiving groove on the second fixture 8 by the spring feeding mechanism 4. Then, the pressing mechanism 5 clamps the spring 20 on the second fixture 8 and puts the spring 20 on the PIN needle 10 on the first fixture 7 located at the pressing mechanism 5. The spring 20 and the PIN needle 10 are pressed together, thereby realizing the automatic assembly of the spring 20 and the PIN needle 10, improving assembly efficiency, reducing labor costs, and reducing appearance scratches caused by manual operation. This ensures the appearance integrity and stability of the product and avoids waste.

[0038] Specifically, in this embodiment, the PIN pin 10 is provided with an abutment portion 101 and an anti-detachment portion 102. The outer diameter of the abutment portion 101 is larger than the outer diameter of the anti-detachment portion 102, and the outer diameter of the anti-detachment portion 102 is slightly larger than the inner diameter of the spring 20 when no radial deformation occurs. The outer diameter of the abutment portion 101 on the PIN pin 10 is larger than the inner diameter of the first receiving groove 71, such as... Figure 5As shown, when the PIN pin 10 is inserted into the first receiving groove 71 on the first fixture 7, the abutting part 101 on the PIN pin 10 is engaged with the top of the first fixture 7, and the anti-dislodgement part 102 is located outside the first receiving groove 71; when the spring 20 is inserted into the second receiving groove on the second fixture 8, the upper end of the spring 20 also extends out of the second receiving groove on the second fixture 8. After the pressing mechanism 5 presses the spring 20 and the PIN pin 10 together, as shown... Figure 15 As shown, the spring 20 is sleeved on the anti-disengagement part 102 of the PIN pin 10 and is press-fitted with the anti-disengagement part 102, and one end of the spring 20 abuts against the abutment part 101.

[0039] Please see Figure 1 , Figure 2 , Figures 4 to 6 As shown, in this embodiment, the conveying mechanism 2 includes two sets of conveying components 21 arranged side by side. Each set of conveying components 21 includes a guide rail 211 fixedly mounted on the frame 1 and a base 212 slidably mounted on the guide rail 211. At least one first fixture 7 is provided on each of the two bases 212. The two bases 212 slide along the corresponding guide rail 211 under the drive of the same driving device, so as to realize the conveying of the first fixture 7 on the two bases 212 between the PIN needle feeding mechanism 3 and the pressing mechanism 5. In this embodiment, when the first fixture 7 on one set of conveying components 21 is conveyed to the PIN needle feeding mechanism 3, the first fixture 7 on the other set of conveying components 21 is conveyed to the pressing mechanism 5. In this embodiment, two sets of conveying components 21 are used to convey different first fixtures 7 respectively. This allows the PIN pin 10 in the first fixture 7 on one set of conveying components 21 to be pressed against the spring 20 by the pressing mechanism 5, while the PIN pin feeding mechanism 3 feeds the PIN pin 10 into the first fixture 7 on the other set of conveying components 21, which can greatly improve assembly efficiency. Furthermore, in this embodiment, the same driving device is used to drive the two bases 212 to slide along the corresponding guide rails 211, which can reduce costs and reduce the space occupied by the conveying mechanism 2.

[0040] Specifically, in this embodiment, the driving device includes a first motor 221 and an annular conveyor belt 222 that is drivenly connected to the output shaft of the first motor 221. Two sets of conveying components 21 are distributed on both sides of the annular conveyor belt 222. The annular conveyor belt 222 is drivenly connected to two bases 212 respectively to drive the two bases 212 to slide along the corresponding guide rails 211. The driving device also includes a driving pulley 223 and a driven pulley (not shown in the figure). The annular conveyor belt 222 is sleeved on the driving pulley 223 and the driven pulley. The output shaft of the first motor 221 drives the annular conveyor belt 222 to move through the driving pulley 223. Limiting members 24 are respectively provided on the frame 1 at both ends corresponding to the bases 212 to limit the sliding stroke of the bases 212 between the PIN needle feeding mechanism 3 and the pressing mechanism 5.

[0041] Please see Figure 1 , Figure 2 , Figures 4 to 6 As shown, in this embodiment, the conveying assembly 21 further includes a mounting base 213 slidably disposed on the base 212 and a first elastic member 214 disposed between the mounting base 213 and the base 212. A first fixture 7 is disposed on the mounting base 213. The mounting base 213 can slide relative to the base 212 between a first position and a second position. The sliding direction of the mounting base 213 relative to the base 212 is perpendicular to the sliding direction of the base 212 on the guide rail 211, and the direction in which the mounting base 213 slides towards the first position is a direction that gradually approaches the other conveying assembly 21. The mounting base 213 can be reset from the second position to the first position under the action of the first elastic member 214, so that the first fixtures 7 on both mounting bases 213 are in the same position when conveyed to the PIN needle feeding mechanism 3, and so that the first fixtures 7 on both mounting bases 213 are in the same position. The first fixture 7 is conveyed to the pressing mechanism 5 and is in the same position when it is pressed, so that the pin insertion position of the PIN feeding mechanism 3 is fixed each time, and the pressing position of the pressing mechanism 5 is fixed each time. This makes the equipment more efficient in assembly, and the overall structure of the equipment is more compact, reducing the space occupied and saving costs. A partition 23 is fixedly set between the two guide rails 211. The partition 23 is specifically set between the middle positions of the two guide rails 211. The two ends of the partition 23 along the length of the guide rail 211 are respectively provided with guide slopes 231 corresponding to the two mounting seats 213. During the sliding process, the two mounting seats 213 can slide from the first position to the second position under the action of the guide slopes 231, so that the two mounting seats 213 move away from each other to make room for each other and avoid interference between the two mounting seats 213.

[0042] Specifically, in this embodiment, a roller 215 is provided on the mounting base 213 corresponding to the partition 23 to reduce the friction between the mounting base 213 and the partition 23 when the mounting base 213 slides past the partition 23.

[0043] Please see Figure 1 , Figure 2 , Figures 10 to 14As shown, in this embodiment, the pressing mechanism 5 includes a first gripper mechanism 51, a first horizontal drive mechanism 52 for driving the first gripper mechanism 51 to move horizontally between the first fixture 7 and the second fixture 8 located at the pressing mechanism 5, and a first vertical drive mechanism 53 for driving the first gripper mechanism 51 to move up and down reciprocally. The first gripper mechanism 51 includes at least two first grippers 511 for gripping the spring 20, and a first gripper drive mechanism 512 connected to the first grippers 511 to drive the first grippers 511 to open and close. In this embodiment, the first horizontal drive mechanism 52 drives the first gripper mechanism 51 to move above the second fixture 8. The first vertical drive mechanism 53 drives the first gripper mechanism 51 to move down and clamp the spring 20 on the second fixture 8. Then, the first gripper mechanism 51 is driven to move up and down. The first horizontal drive mechanism 52 drives the first gripper mechanism 51 to move above the first fixture 7 located at the pressing mechanism 5. Then, the first vertical drive mechanism 53 drives the first gripper mechanism 51 to move down so that the spring 20 is sleeved on the PIN pin 10 on the first fixture 7 and the spring 20 and the PIN pin 10 are pressed together to form a connector.

[0044] Specifically, in this embodiment, the first up-and-down driving mechanism 53 is mounted on the first horizontal driving mechanism 52. The first horizontal driving mechanism 52 drives the first up-and-down driving mechanism 53 to move horizontally. The first horizontal driving mechanism 52 includes a first horizontal slide block 521 that is slidably mounted on the frame 1 and a first horizontal cylinder 522 mounted on the frame 1 for driving the first horizontal slide block 521 to slide. The first up-and-down driving mechanism 53 includes a first up-and-down slide block 531 that is slidably mounted on the first horizontal slide block 521 and a first up-and-down cylinder 532 mounted on the first horizontal slide block 521 for driving the first up-and-down slide block 531 to slide. The first gripper mechanism 51 is mounted on the bottom of the first up-and-down slide block 531. Of course, in other embodiments, the first horizontal driving mechanism 52 can also be mounted on the first up-and-down driving mechanism 53, and the first up-and-down driving mechanism 53 drives the first horizontal driving mechanism 52 to move up and down reciprocally, which can also achieve the purpose of the present invention.

[0045] Please see Figure 1 , Figure 2 , Figures 10 to 14As shown, in this embodiment, the first gripper mechanism 51 further includes a guide sleeve 513 disposed between each first gripper 511 and open at the bottom. The sidewall of the guide sleeve 513 is provided with a first clearance notch 5131 corresponding to each first gripper 511. The inner diameter of the guide sleeve 513 is larger than the outer diameter of the upper end of the second fixture 8, so that the guide sleeve 513 can be fitted outside the upper end of the second fixture 8 to play a guiding role, so that the first gripper mechanism 51 can accurately grip the spring 20. The inner diameter of the guide sleeve 513 is larger than the outer diameter of the upper end of the first fixture 7, so that when the first gripper mechanism 51 fits the spring 20 on the PIN pin 10 and presses the spring 20 and the PIN pin 10 together, the guide sleeve 513 can be fitted outside the upper end of the first fixture 7. The first gripper 511 can be inserted into the guide sleeve 513 through the first clearance notch 5131 to grip the spring 20.

[0046] Specifically, in this embodiment, the guide sleeve 513 is specifically mounted on the housing of the first gripper drive mechanism 512. Please refer to [link to relevant documentation]. Figure 8 and Figure 9 As shown, a fixed seat 9 is provided on the frame 1, and a second fixture 8 is installed on the fixed seat 9. The upper end of the second fixture 8 is provided with a second clearance notch 81 corresponding to the first gripper 511. The first gripper 511 can be inserted into the second receiving groove of the second fixture 8 through the second clearance notch 81 to grip the spring 20. The first gripper mechanism 51 has two first grippers 511.

[0047] Please see Figure 1 , Figure 2 , Figures 10 to 14 As shown, in this embodiment, the first gripper mechanism 51 further includes a guide seat 514 disposed on the top of the guide sleeve 513, a guide pin 515 slidably disposed on the guide seat 514 and extending downward into the guide sleeve 513, and a second elastic member 516 for sliding the guide pin 515 downward to reset it; when the pressing mechanism 5 grips the spring 20 on the second fixture 8 (i.e., when the first gripper mechanism 51 grips the spring 20 on the second fixture 8), the guide pin 515 is inserted into the spring 20 to guide it and prevent the spring 20 from deviating. The first gripper mechanism 51 can more accurately grip the spring 20 by shifting or tilting the spring 20 onto the pin 10 on the first fixture 7 and pressing the spring 20 onto the pin 10. When the pressing mechanism 5 puts the spring 20 onto the pin 10 on the first fixture 7 and presses the spring 20 onto the pin 10, the guide pin 515 can overcome the elastic force of the second elastic element 516 and move upward to make way for the pin 10 under the pushing action of the pin 10. In this process, the guide pin 515 plays a guiding role to prevent the spring 20 from tilting or twisting, so that the spring 20 can be accurately put onto the pin 10 and pressed.

[0048] Specifically, in this embodiment, the guide seat 514 and the guide sleeve 513 are an integral structure. An abutment 517 is installed on the guide seat 514, and the second elastic member 516 is abutted between the guide pin 515 and the abutment 517. The first elastic member 214 and the second elastic member 516 are both springs.

[0049] Please see Figure 1 , Figure 2 and Figure 10 As shown, this embodiment also includes a feeding mechanism 6 mounted on the frame 1. The feeding mechanism 6 includes a material container 61 fixedly mounted on the frame 1 and a feeding gripper mechanism 62 for clamping the pressed spring 20 and PIN pin 10. While the first horizontal drive mechanism 52 drives the first gripper mechanism 51 to move horizontally between the first fixture 7 and the second fixture 8 located at the pressing mechanism 5, the first horizontal drive mechanism 52 is also used to drive the feeding gripper mechanism 62 to move horizontally between the material container 61 and the first fixture 7 located at the pressing mechanism 5. That is, the first gripper mechanism 51 and the feeding gripper mechanism 62 share the same horizontal drive mechanism, which can reduce the space occupied by the equipment and reduce the cost. The first vertical drive mechanism 53 is used to drive the first gripper mechanism 51 and the feeding gripper mechanism 62 to move up and down reciprocally at the same time. That is, the first gripper mechanism 51 and the feeding gripper mechanism 62 share the same vertical drive mechanism, which can further reduce the space occupied by the equipment and reduce the cost.

[0050] Specifically, in this embodiment, the material container 61 and the second fixture 8 are distributed on both sides of the conveying mechanism 2; the unloading claw mechanism 62 includes at least two unloading claws 621 for gripping the assembled spring 20 and PIN pin 10, and an unloading claw drive mechanism 622 connected to the unloading claws 621 to drive the unloading claws 621 to open and close. The unloading claw drive mechanism 622 is specifically installed at the bottom of the first upper and lower slide block 531.

[0051] Please see Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the PIN feeding mechanism 3 includes a second gripper mechanism 31 for gripping the PIN pins 10, a tray 32 on which a plurality of PIN pins 10 are placed, a second horizontal drive mechanism for driving the second gripper mechanism 31 to move horizontally between above the tray 32 and above the first fixture 7 located at the PIN feeding mechanism 3, and a second vertical drive mechanism 34 for driving the second gripper mechanism 31 to move vertically back and forth. The second gripper mechanism 31 includes at least two second grippers 311 for gripping the PIN pins 10, and a second gripper drive mechanism 312 connected to the second grippers 311 to drive the second grippers 311 to open and close. In this embodiment, the second gripper mechanism 31 is mounted on the second vertical drive mechanism 34, and the second vertical drive mechanism 34 is mounted on the second horizontal drive mechanism. Of course, in other embodiments, the second gripper mechanism 31 can also be mounted on the second horizontal drive mechanism, and the second horizontal drive mechanism can be mounted on the second vertical drive mechanism 34.

[0052] Specifically, in this embodiment, the tray 32 has a plurality of slots (not shown in the figure) arranged in a matrix for vertical insertion of PIN pins 10. The second horizontal drive mechanism includes an X-axis horizontal drive mechanism 331 and a Y-axis horizontal drive mechanism 332. The direction in which the X-axis horizontal drive mechanism 331 drives the second gripper mechanism 31 is perpendicular to the direction in which the Y-axis horizontal drive mechanism 332 drives the second gripper mechanism 31. The Y-axis horizontal drive mechanism 332 includes a second motor 3321 mounted on the frame 1 and a Y-axis horizontal slide block 3322 slidably mounted on the frame 1.

Of course, in other embodiments, the first gripper drive mechanism 512, the second gripper drive mechanism 312, the unloading gripper drive mechanism 622 and the third gripper drive mechanism 422 may also be motors.

[0055] Please see Figures 1 to 14As shown, in this embodiment, each base 212 is provided with two first fixtures 7 (i.e., each mounting base 213 is fixedly provided with two first fixtures 7). Correspondingly, two second up-and-down driving mechanisms 34 are installed on the X-axis horizontal slide 3312. The bottom of the second up-and-down sliding base 341 of each second up-and-down driving mechanism 34 is provided with a second gripper driving mechanism 312. The two second gripper driving mechanisms 312 are used to insert the PIN pin 10 into the two first fixtures 7 on each base 212 respectively. Two second fixtures 8 are also correspondingly provided on the frame 1. Spring feeding mechanism 4 is also provided with two, for inserting the spring 20 into the second receiving groove on the two second fixtures 8 respectively. The bottom of the first upper and lower sliding base 531 is provided with two first gripper mechanisms 51 and two unloading gripper mechanisms 62. The two first gripper mechanisms 51 are used to grip the spring 20 on the two second fixtures 8 respectively and put the spring 20 on the PIN pin 10 on the two first fixtures 7 on the base 212 and press them together. The two unloading gripper mechanisms 62 are used to grip the pressed connector on the two first fixtures 7 on the base 212 and unload it into the material box 61.

[0056] The operating principle of this embodiment is briefly described as follows:

[0057] The PIN pins 10 are manually placed and inserted into the slots on the tray 32 beforehand. In the initial state, both mounting bases 213 are in the first position under the action of the first elastic element 214. Among the two bases 212, the first fixture 7 on one base 212 is located at the PIN pin feeding mechanism 3, and the first fixture 7 on the other base 212 is located at the pressing mechanism 5.

[0058] During operation, the second horizontal drive mechanism drives the second gripper mechanism 31 to move above the material tray 32. The second up-down drive mechanism 34 drives the second gripper mechanism 31 to move down and grab the PIN needle 10 on the material tray 32. Then, the second horizontal drive mechanism drives the second gripper mechanism 31 to move above the first fixture 7 located at the PIN needle feeding mechanism 3. The second up-down drive mechanism 34 drives the second gripper mechanism 31 to move down and insert the PIN needle 10 into the first receiving groove 71 on the first fixture 7. Then, the second gripper mechanism 31 moves up to reset. At the same time, the third horizontal drive mechanism 44 drives the third gripper mechanism to move above the end of the feeding track 43. The third up-down drive mechanism 45 drives the third gripper mechanism to move down and grab the horizontally placed spring 20. Then, the third gripper mechanism moves up. The rotation drive mechanism 46 drives the third gripper mechanism to rotate 90° so that the spring 20 is in a vertical state. The third horizontal drive mechanism 44 drives the third gripper mechanism to move above the second fixture 8. The third up-down drive mechanism 45 drives the third gripper mechanism to move down and insert the spring 20 into the second receiving groove.

[0059] Then, the first motor 221 drives the base 212 to slide along the guide rail 211 via the annular conveyor belt 222 to convey the first fixture 7 (containing the PIN needle 10) located at the PIN needle feeding mechanism 3 to the pressing mechanism 5. At the same time, the empty first fixture 7 located at the pressing mechanism 5 is conveyed in the opposite direction to the PIN needle feeding mechanism 3. During this process, the two mounting seats 213 slide from the first position to the second position under the action of the guide inclined surface 231, so that the two mounting seats 213 move away from each other to make room for each other and avoid interference between the two mounting seats 213. After the mounting seats 213 slide past the partition 23, the mounting seats 213 are reset to the first position under the action of the first elastic member 214.

[0060] The first horizontal drive mechanism 52 drives the first gripper mechanism 51 to move above the second fixture 8 and align the sleeve with the second fixture 8. Simultaneously, the first horizontal drive mechanism 52 drives the unloading gripper mechanism 62 to move above the first fixture 7 located at the pressing mechanism 5. The first gripper drive mechanism 512 drives the first gripper to open and hold. The first vertical drive mechanism 53 drives the first gripper mechanism 51 to move downwards, causing the guide sleeve 513 to be fitted over the upper end of the second fixture 8, and the guide pin 515 to be inserted into the spring 20. The first gripper drive mechanism 512 then drives the first gripper to close, causing the first... After the gripper passes through the first clearance notch 5131 and the second clearance notch 81 in sequence, it picks up the spring 20 in the second receiving groove. Subsequently, the first up-down drive mechanism 53 drives the first gripper mechanism 51 to move upward, and the first horizontal drive mechanism 52 drives the first gripper mechanism 51 to move above the first fixture 7 located at the pressing mechanism 5, aligning the guide sleeve 513 with the first fixture 7. The hole in the middle of the spring 20 is aligned with one end of the PIN pin 10. At the same time, the first horizontal drive mechanism 52 drives the unloading gripper mechanism 62 to move above the material container 61, and the first up-down drive mechanism 53 drives the first gripper... Mechanism 51 moves downward, causing spring 20 to be sleeved on PIN pin 10 and pressing spring 20 and PIN pin 10 together. During the pressing process, guide pin 515 moves upward against the elastic force of second elastic element 516 under the pushing action of PIN pin 10 to make way for PIN pin 10. First gripper mechanism 51 always clamps spring 20 and presses spring 20 down, causing spring 20 to undergo a certain radial deformation and then be sleeved on the anti-disengagement part 102 and interference-fitted with the anti-disengagement part 102, and finally causing one end of spring 20 to abut against the abutment part 101 on PIN pin 10; subsequently, the second... A gripper mechanism 51 releases the spring 20. A first up-down drive mechanism 53 drives the first gripper mechanism 51 and the unloading gripper mechanism 62 to move upward. A first horizontal drive mechanism 52 drives the first gripper mechanism 51 to move above the second fixture and drives the unloading gripper mechanism 62 to move above the first fixture 7. A first up-down drive mechanism 53 drives the first gripper mechanism 51 to move downward and grip the spring 20, and drives the unloading gripper mechanism 62 to move downward and grip the pressed spring 20 and PIN pin 10. A first up-down drive mechanism 53 drives the first gripper mechanism 51 and the unloading gripper mechanism 62 to move upward.

[0061] Next, the first motor 221 drives the base 212 to slide along the guide rail 211 via the annular conveyor belt 222, so as to convey the first fixture 7 (containing the PIN needle 10) located at the PIN needle feeding mechanism 3 to the pressing mechanism 5, and at the same time, the empty first fixture 7 located at the pressing mechanism 5 is conveyed in the opposite direction to the PIN needle feeding mechanism 3; at the same time, the first horizontal drive mechanism 52 drives the first gripper mechanism 51 to move above the first fixture 7 located at the pressing mechanism 5, and drives the unloading gripper mechanism 62 to move above the material box 61. The first vertical drive mechanism 53 drives the first gripper mechanism 51 and the unloading gripper mechanism 62 to move down. The unloading gripper mechanism 62 releases the pressed spring 20 and the PIN needle 10 so that they fall into the material box 61. At the same time, the first gripper mechanism 51 presses another spring 20 and another PIN needle 10 together. This cycle is repeated to realize the automatic assembly of the spring 20 and the PIN needle 10.

[0062] In other embodiments, the driving device includes a first motor and an annular conveyor chain that is driven by the output shaft of the first motor. Two sets of conveying components are distributed on both sides of the annular conveyor chain. The annular conveyor chain is driven by two bases respectively to drive the two bases to slide along the corresponding guide rails. This also enables the two bases to slide along the corresponding guide rails using the same driving device. Furthermore, in this embodiment, the driving device also includes a driving sprocket and a driven sprocket (not shown in the figure). The annular conveyor chain is sleeved on the driving sprocket and the driven sprocket. The output shaft of the first motor drives the annular conveyor chain to move through the driving sprocket.

[0063] In other embodiments, the two bases slide along corresponding guide rails under the drive of different driving devices to transfer the first fixture on the two bases between the PIN feeding mechanism and the pressing mechanism; further, in this embodiment, two cylinder driving devices or motor driving devices can be used to drive the two bases to slide along corresponding guide rails respectively.

[0064] As can be seen from the above description of the present invention, compared with the prior art, the device for assembling PIN pins and springs of the present invention inserts PIN pins into the first receiving groove on the first fixture through a PIN pin feeding mechanism, conveys the first fixture between the PIN pin feeding mechanism and the pressing mechanism through a conveying mechanism, inserts springs into the second receiving groove on the second fixture through a spring feeding mechanism, then clamps the spring on the second fixture through the pressing mechanism, and then puts the spring on the PIN pin on the first fixture located at the pressing mechanism and presses the spring and PIN pin together, thereby realizing the automatic assembly of springs and PIN pins, improving assembly efficiency, reducing labor costs, and reducing appearance scratches caused by manual operation, ensuring the appearance integrity and stability of the product, and avoiding waste.

However, the present invention is not limited to the embodiments.
