Description

Technical Field

[0001] This invention belongs to the technical field of automated equipment, and in particular relates to a keyboard torsion spring assembly line. Background Technology

[0002] A torsion spring, also known as a torsion spring, is a helical spring that withstands torsional deformation. Its working part is tightly wound into a helical spring body, while the end structure consists of torsion arms of various shapes. Therefore, it is a mechanical part that stores and releases energy through elastic deformation. The main functions of a torsion spring include controlling the movement of machine parts, mitigating impacts or vibrations, storing energy, measuring the magnitude of force, and driving the resetting of mechanical structures and controlling the movement of various mechanical components.

[0003] When torsion springs are used in keyboards, they utilize their elastic properties to provide a restoring force to the keys, ensuring that the keys quickly return to their original position after being pressed. In traditional keyboard production lines, the installation of torsion springs in the keyboard's mounting area is typically done manually. However, the skill level, experience, workload, and fatigue of the assembly personnel can all affect the inconsistency of assembly quality. Summary of the Invention

[0004] The purpose of this invention is to provide a keyboard torsion spring assembly line to address the technical deficiencies described in the background section.

[0005] The keyboard torsion spring assembly production line includes: a conveyor line, which is equipped with a feeding station and an assembly station. The assembly station is equipped with a material preparation mechanism and a transverse drive module. The material preparation mechanism is used to store and supply torsion springs. The transverse drive module drives a transverse plate. A longitudinal drive module is installed on the transverse plate. The longitudinal drive module drives a longitudinal plate. A lifting drive module is installed on the longitudinal plate. The lifting drive module drives a lifting plate. A clamp is provided on the lifting plate.

[0006] After the loading station loads the keyboard that needs to be fitted with torsion springs onto the conveyor line and transports it to the assembly station, the transverse drive module drives the transverse plate to move laterally, the longitudinal drive module drives the longitudinal plate to move longitudinally, and the lifting drive module drives the lifting plate to move up and down, so as to drive the fixture to place the torsion spring into the mounting position of the keyboard.

[0007] Based on the above technical solution, the present invention achieves the following beneficial effects:

[0008] By using a mechanical mechanism to place the torsion spring into the keyboard mounting position instead of traditional manual labor, the assembly quality of the keyboard can be effectively avoided by the skill level, experience, workload, and fatigue of the assembly personnel, thereby improving the yield rate of each keyboard.

[0009] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0010] In some torsion spring assembly stations, due to the relatively small size of the torsion spring and the limited space in the keyboard mounting area, even a slight displacement of the torsion spring or the keyboard mounting area can affect the assembly quality or even prevent the assembly from being completed.

[0011] Therefore, based on the aforementioned technical problem, in some embodiments, an industrial camera is mounted on the longitudinal moving plate, a rotary drive mechanism is mounted on the lifting plate, the rotary drive mechanism drives a rotating frame, and a fixture is mounted on the rotating frame.

[0012] Before the fixture picks up the torsion spring, an industrial camera is used to acquire the position and orientation of the torsion spring, and / or the position of the mounting position. During the period when the fixture places the torsion spring into the mounting position of the keyboard, the lateral drive module drives the lateral plate to move laterally and / or the longitudinal drive module drives the longitudinal plate to move longitudinally and / or the rotation drive mechanism drives the rotating frame to move the fixture and / or rotate it, so that the torsion spring on the fixture is moved and / or rotated and snapped, slid into or placed into the mounting position.

[0013] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0014] When a torsion spring is installed in the keyboard mounting area, the torsion spring or the keyboard mounting area may shift. By using an industrial camera to obtain the position and orientation of the torsion spring and / or the position of the mounting location before the fixture picks up the torsion spring, the position and / or orientation angle of the torsion spring can be adjusted during the fixture's placement of the torsion spring into the keyboard mounting location, thereby improving production stability.

[0015] In some embodiments: the mounting position is provided with a mounting groove, the top of the mounting groove is provided with an inclined guide surface, an avoidance channel is provided on one side of the mounting groove, a blocking block is provided at the bottom of the avoidance channel, and the top surface of the blocking block is provided with an inclined sliding surface.

[0016] The rotating frame is equipped with a first spring and a second spring. The first spring pushes a first pressure rod, and the second spring pushes a second pressure rod. There is a height difference between the first pressure rod and the second pressure rod.

[0017] When the torsion spring is placed in the mounting position, the inclined guide surface guides the spring body of the torsion spring into the mounting groove. Subsequently, the lifting drive module drives the lifting plate to descend, so that when the first pressure rod presses the spring body into the lowest end of the mounting groove, the lowest end of the mounting groove supports the spring body and restricts the descent of the spring body, while the spring body prevents the first pressure rod from continuing to descend. At this time, the second pressure rod presses down the first torsion arm of the torsion spring from the clearance channel. The first torsion arm passes over the locking block through the inclined sliding surface, so that the first torsion arm is locked under the locking block, thereby fixing the torsion spring in the mounting groove and providing a fulcrum when the torsion spring is subjected to torsional force.

[0018] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects:

[0019] 1. Only one power source is needed to drive the lifting (i.e., the lifting drive module drives the lifting plate to descend), which can continuously push components of different heights (i.e., the spring body and the first torsion arm) into different heights (i.e., the bottom of the mounting slot and below the locking block) in sequence.

[0020] 2. During the process of pushing the second pressure rod to push the first torsion arm past the jamming block, the resistance of the first pressure rod is absorbed by the first spring, thereby protecting the spring body of the torsion spring and avoiding pressure damage.

[0021] In some embodiments, a movable groove is provided on the other side of the mounting groove, and a limiting part is provided at the top of the movable groove, with an outer sliding surface provided at one corner of the limiting part groove.

[0022] The rotating frame is equipped with a third pressure rod, which has a height difference from the first pressure rod. The bottom end of the third pressure rod is provided with an outward pushing surface.

[0023] While the first pressure rod presses the spring body into the lowest end of the mounting groove, the third pressure rod presses down on the second torsion arm of the torsion spring. At the same time, the outer pushing surface of the third pressure rod pushes the second torsion arm outward, causing the second torsion arm to slide across the outer sliding surface until the outer sliding surface passes the limiting part and enters the movable groove. At this time, the second torsion arm can slide in the movable groove, and the limiting part restricts the second torsion arm from sliding out of the movable groove.

[0024] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects:

[0025] 1. Since the second torsion arm can slide within the movable groove, and the limiting part restricts the second torsion arm from sliding out of the movable groove, when the torsion spring resets a component of the keyboard through the second torsion arm, it can prevent the second torsion arm from applying excessive force to that component of the keyboard, which would cause damage, reduce service life, and affect the feel of use.

[0026] 2. Because the limiting part restricts the second torsion arm from sliding out of the movable groove, and at the same time, the locking block provides a fulcrum for the first torsion arm of the torsion spring when it is subjected to torsional force, the torsion spring can be effectively prevented from falling out of the mounting groove during operation.

[0027] 3. During torsion spring installation, only one action and one power (i.e., the lifting drive module drives the lifting plate to descend) are needed to press the spring body into the lowest end of the installation slot, slide the first torsion arm under the locking block, and lock the second torsion arm into the movable slot. This will reduce the preparation cost of the workstation, reduce the space occupation of the workstation, and simplify the operation logic of the operating system.

[0028] In some embodiments, a fixing cylinder is mounted on the rotating frame, and the fixing cylinder drives a fixing lever so that the fixing cylinder drives the fixing lever to press down the fixing keyboard before the first lever presses the spring body into the lowest end of the mounting groove.

[0029] Based on the aforementioned technical solution, the clamp can more accurately and stably place the torsion spring into the mounting area, the first pressure rod can more accurately and stably press the spring body into the lowest end of the mounting groove, the second pressure rod can more accurately and stably slide the first torsion arm under the locking block, and the third pressure rod can more accurately and stably lock the second torsion arm into the movable groove.

[0030] In some torsion spring assembly stations, in order to optimize the space occupied when storing torsion springs and to avoid the torsion springs from getting tangled together, these torsion springs are stored at a specific angle. When the torsion springs stored at these angles need to be installed on the product at another angle, the orientation angle of the springs stored at the specific angle needs to be adjusted.

[0031] Therefore, in some embodiments, the assembly station is also equipped with a flipping mechanism; the flipping mechanism includes a base, a flipping seat is connected to the base by a bearing, the top surface of the flipping seat is provided with a placement groove for placing a torsion spring, one side of the flipping seat is provided with an arc surface and the other side is provided with a limiting surface, an upward push cylinder is installed below the arc surface, the upward push cylinder drives a spherical push block that can slide on the arc surface, and the base is provided with a tension spring connected to the side of the limiting surface.

[0032] After the torsion spring is placed into the placement slot by the material preparation mechanism, the position and orientation of the torsion spring are obtained by an industrial camera. The upward push cylinder drives the ball push block to push the flipping seat to rotate. The flipping seat drives the torsion spring in the placement slot to adjust to an angle that can be installed in the mounting position, so that the clamp can pick up the torsion spring after the angle adjustment from the placement slot. After that, the upward push cylinder drives the ball push block to reset, and the tension spring pulls the placement seat to reset. At this time, the limiting surface contacts the base.

[0033] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects:

[0034] 1. Since the torsion spring can be adjusted to the angle that allows it to be installed in the mounting position before being placed or installed in the keyboard, several torsion springs can be placed at a specific angle when stored in the preparation mechanism, thereby optimizing the space occupied when storing the torsion springs and preventing them from getting tangled together.

[0035] 2. When these torsion springs are stored at a specific angle, and these torsion springs stored at this angle need to be installed on the product at another angle, the torsion springs can be adjusted to the angle that allows them to be installed in the mounting position, or the torsion springs can be flipped to adjust their orientation angle so that the torsion springs can be installed in the keyboard mounting area.

[0036] 3. When loading springs that are stored haphazardly, the torsion spring can be adjusted to an angle that allows it to be installed in the mounting position, thus enabling the torsion spring to be installed in the keyboard mounting area.

[0037] In some embodiments, the flipping mechanism further includes a transfer drive module, one end of which is located next to the material preparation mechanism. The transfer drive module drives a drive block that is located away from the material preparation mechanism and close to the fixture, and a base is mounted on the drive block.

[0038] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects: after the material preparation mechanism places the torsion spring in the placement slot, the transfer drive module drives the drive block to move away from the material preparation mechanism, so that there is enough space above the material discharge slot for the fixture to move, thereby enabling the fixture to stably and efficiently clamp the torsion spring in the material discharge slot.

[0057] To make the objectives, technical solutions, and advantages of this invention clearer, this specific embodiment will be described in further detail with reference to the accompanying drawings.

[0058] In traditional keyboard 4 production lines, the installation of torsion springs 7 is typically done manually in the mounting area of ​​the keyboard 4. However, the skill level, experience, workload, and fatigue of the assembly personnel can all affect the instability of the assembly quality. Therefore, this specific embodiment provides a keyboard torsion spring assembly production line.

[0059] like Figures 1 to 15 As shown, the keyboard torsion spring assembly production line includes a conveyor line 1, which is equipped with a feeding station 11 and an assembly station. The assembly station is equipped with a material preparation mechanism 2 and a transverse drive module 3. The material preparation mechanism 2 is used to store and supply torsion springs 7. The transverse drive module 3 drives a transverse plate 31. A longitudinal drive module 32 is installed on the transverse plate 31. The longitudinal drive module 32 drives a longitudinal plate 33. A lifting drive module 34 is installed on the longitudinal plate 33. The lifting drive module 34 drives a lifting plate 35. A clamp 38 is provided on the lifting plate 35.

[0060] The material preparation mechanism 2 can be composed of a feeding tray and a feeding module. The feeding module is used to take out the torsion spring 7 stored in the feeding tray.

[0061] After the loading station 11 loads the keyboard 4, which needs to be fitted with torsion spring 7, onto the conveyor line 1 and transports it to the assembly station, the transverse drive module 3 drives the transverse plate 31 to move laterally, the longitudinal drive module 32 drives the longitudinal plate 33 to move longitudinally, and the lifting drive module 34 drives the lifting plate 35 to lift, so as to drive the fixture 38 to place the torsion spring 7 into the mounting position 40 of the keyboard 4.

[0062] The installation of the keyboard 4 is completed by placing the torsion spring 7 into the mounting position 40 of the keyboard 4 through a mechanical mechanism instead of traditional manual labor. This effectively avoids the impact of the assembly personnel's skill level, experience, workload, and fatigue on the assembly quality of the keyboard 4, thereby improving the yield rate of each keyboard 4.

[0063] In some torsion spring 7 assembly stations, due to the relatively small size of the torsion spring 7 and the limited space of the keyboard 4 mounting area, even a slight displacement of the torsion spring 7 or the keyboard 4 mounting area can affect the assembly quality or even prevent the assembly from being completed.

[0064] Therefore, in some embodiments, an industrial camera 39 is mounted on the longitudinal transfer plate 33, a rotary drive mechanism 36 is mounted on the lifting plate 35, the rotary drive mechanism 36 drives a rotating frame 37, and a clamp 38 is mounted on the rotating frame 37.

[0065] Before the clamp 38 picks up the torsion spring 7, the industrial camera 39 is used to acquire the position and orientation of the torsion spring 7 and / or the position of the mounting position 40, so that while the clamp 38 is placing the torsion spring 7 into the mounting position 40 of the keyboard 4, the transverse drive module 3 drives the transverse plate 31 to move laterally and / or the longitudinal drive module 32 drives the longitudinal plate 33 to move longitudinally and / or the rotation drive mechanism 36 drives the rotating frame 37 to move the clamp 38 and / or rotate it, so that the torsion spring 7 on the clamp 38 is moved and / or rotated and snapped, slid into or placed into the mounting.

[0066] When the torsion spring 7 is installed in the mounting area of ​​the keyboard 4, the torsion spring 7 or the mounting area of ​​the keyboard 4 may shift. Before the clamp 38 picks up the torsion spring 7, the position and orientation of the torsion spring 7 and / or the position of the mounting position 40 are obtained by the industrial camera 39. Then, while the clamp 38 is placing the torsion spring 7 into the mounting position 40 of the keyboard 4, the position and / or orientation angle of the torsion spring 7 are adjusted to place or install the torsion spring 7 into the mounting area of ​​the keyboard 4, thereby improving the stability of production.

[0067] In some embodiments, the mounting position 40 is provided with a mounting groove 41, the top of the mounting groove 41 is provided with an inclined guide surface 411, a clearance channel 42 is provided on one side of the mounting groove 41, a locking block 421 is provided at the bottom of the clearance channel 42, and an inclined sliding surface 422 is provided on the top surface of the locking block 421.

[0068] The rotating frame 37 is equipped with a first spring 51 and a second spring 52. The first spring 51 pushes a first pressure rod 511, and the second spring 52 pushes a second pressure rod 521. There is a height difference between the first pressure rod 511 and the second pressure rod 521.

[0069] When the torsion spring 7 is placed in the mounting position 40, the inclined guide surface 411 guides the spring body of the torsion spring 7 into the mounting groove 41. Subsequently, the lifting drive module 34 drives the lifting plate 35 to descend, so that when the first pressure rod 511 presses the spring body into the lowest end of the mounting groove 41, the lowest end of the mounting groove 41 supports the spring body and restricts the descent of the spring body, while the spring body prevents the first pressure rod 511 from continuing to descend. At this time, the second pressure rod 521 presses down the first torsion arm 71 of the torsion spring 7 from the clearance channel 42. The first torsion arm 71 passes over the locking block 421 through the inclined sliding surface 422, so that the first torsion arm 71 is locked under the locking block 421, thereby fixing the torsion spring 7 in the mounting groove 41 and providing a fulcrum when the torsion spring 7 is subjected to torsional force.

[0070] Since only one power source is needed to drive the lifting (i.e., the lifting drive module 34 drives the lifting plate 35 to descend), it is possible to continuously push components of different heights (i.e., the spring body and the first torsion arm 71) into different heights (i.e., the bottom of the mounting slot 41 and below the locking block 421) in sequence.

[0071] During the process of pushing the second pressure rod 521 to push the first torsion arm 71 past the block 421, the resistance of the first pressure rod 511 is absorbed by the first spring 51, thereby protecting the spring body of the torsion spring 7 and avoiding pressure damage.

[0072] In some embodiments, a movable groove 43 is provided on the other side of the mounting groove 41, a limiting part 431 is provided at the top of the movable groove 43, and an outer sliding surface 432 is provided at one corner of the limiting part 431.

[0073] The rotating frame 37 is equipped with a third pressure rod 53. The third pressure rod 53 has a height difference from the first pressure rod 511. The bottom end of the third pressure rod 53 is provided with an outward pushing surface 531.

[0074] While the first pressure rod 511 presses the spring body into the lowest end of the mounting groove 41, the third pressure rod 53 presses down on the second torsion arm 72 of the torsion spring 7. At this time, the outer push surface 531 of the third pressure rod 53 pushes the second torsion arm 72 outward to move, so that the second torsion arm 72 slides over the outer sliding surface 432 until the outer sliding surface 432 passes the limiting part 431 and enters the movable groove 43. At this time, the second torsion arm 72 can slide in the movable groove 43, and the limiting part 431 restricts the second torsion arm 72 from sliding out of the movable groove 43.

[0075] Since the second torsion arm 72 can slide within the movable groove 43, and the limiting part 431 restricts the second torsion arm 72 from sliding out of the movable groove 43, when the torsion spring 7 resets a component of the keyboard 4 via the second torsion arm 72, it can prevent the second torsion arm 72 from applying excessive force to that component of the keyboard 4, thus avoiding damage, reduced service life, and impact on the feel of use. Furthermore, since the limiting part 431 restricts the second torsion arm 72 from sliding out of the movable groove 43, and the locking block 421 provides a fulcrum for the first torsion arm 71 of the torsion spring 7 when subjected to torsional force, the torsion spring 7 can be effectively prevented from dislodging from the mounting groove 41 during operation.

[0076] During the installation of the torsion spring 7, only one action and one power (i.e., the lifting drive module 34 drives the lifting plate 35 to descend) are needed to press the spring body into the lowest end of the mounting groove 41, slide the first torsion arm 71 into the underside of the locking block 421, and lock the second torsion arm 72 into the movable groove 43, thereby reducing the preparation cost of the workstation, reducing the space occupation of the workstation, and simplifying the operation logic of the operating system.

[0077] In some embodiments, a fixing cylinder 54 is mounted on the rotating frame 37, and the fixing cylinder 54 drives a fixing rod 541 so that the fixing cylinder 54 drives the fixing rod 541 to press down the fixing keyboard 4 before the first pressing rod 511 presses the spring body into the lowest end of the mounting groove 41.

[0078] Therefore, the clamp 38 can more accurately and stably place the torsion spring 7 into the mounting area, the first pressure rod 511 can more accurately and stably press the spring body into the lowest end of the mounting groove 41, the second pressure rod 521 can more accurately and stably slide the first torsion arm 71 under the locking block 421, and the third pressure rod 53 can more accurately and stably lock the second torsion arm 72 into the movable groove 43.

[0079] In some torsion spring 7 assembly stations, in order to optimize the space occupied when storing torsion spring 7 and to avoid the various torsion spring 7 from getting tangled together, these torsion spring 7 are stored at a specific placement angle. When the torsion spring 7 stored at these angles needs to be installed on the product at another angle, the orientation angle of the springs stored at the specific placement angle needs to be adjusted.

[0080] Therefore, in some embodiments, the assembly station is also equipped with a flipping mechanism 6. The flipping mechanism 6 includes a base 61, on which a flipping seat 62 is connected by a bearing. The top surface of the flipping seat 62 is provided with a placement groove 621 for placing a torsion spring 7. One side of the flipping seat 62 is provided with an arc surface 622 and the other side is provided with a limiting surface 623. An upward push cylinder 63 is installed below the arc surface 622. The upward push cylinder 63 drives a spherical push block 631 that can slide on the arc surface 622. The base 61 is provided with a tension spring 64 connected to the side of the limiting surface 623.

[0081] After the material preparation mechanism 2 places the torsion spring 7 into the placement slot 621, the position and orientation of the torsion spring 7 are obtained by the industrial camera 39. The upward push cylinder 63 drives the ball push block 631 to push the flipping seat 62 to rotate. The flipping seat 62 drives the torsion spring 7 in the placement slot 621 to adjust to an angle that can be installed in the mounting position 40, so that the clamp 38 can clamp the torsion spring 7 after the angle adjustment from the placement slot 621. After that, the upward push cylinder 63 drives the ball push block 631 to reset, and the tension spring 64 pulls the placement seat to reset. At this time, the limiting surface 623 contacts the base 61.

[0082] Since the torsion spring 7 can be adjusted to an angle that allows it to be installed in the mounting position 40 before being placed or installed in the mounting position 40 of the keyboard 4, when several torsion springs 7 are stored in the preparation mechanism 2, they can be placed at a specific angle, thereby optimizing the space occupied by the torsion springs 7 during storage and preventing the individual torsion springs 7 from getting tangled together.

[0083] When these torsion springs 7 are stored at a specific angle, and these torsion springs 7 stored at this angle are to be installed on the product at another angle, the torsion springs 7 can be adjusted to be installed within the mounting position 40, or the torsion springs 7 can be flipped to adjust the orientation angle of the torsion springs 7 so that the torsion springs 7 can be installed in the mounting area of ​​the keyboard 4.

[0084] If, when loading springs that are stored haphazardly, the torsion spring 7 can be adjusted to an angle that allows it to be installed in the mounting position 40, then the torsion spring 7 can be installed in the mounting area of ​​the keyboard 4.

[0085] In some embodiments, the flipping mechanism 6 further includes a transfer drive module 65, one end of which is located next to the material preparation mechanism 2. The transfer drive module 65 drives a drive block 651 that is located away from the material preparation mechanism 2 and close to the clamp 38. The base 61 is mounted on the drive block 651.

[0086] After the material preparation mechanism 2 places the torsion spring 7 into the placement slot 621, the transfer drive module 65 drives the drive block 651 to move away from the material preparation mechanism 2, so that there is enough space above the material discharge slot for the clamp 38 to move, thereby enabling the clamp 38 to stably and efficiently clamp the torsion spring 7 in the material discharge slot.

[0087] To further illustrate the keyboard torsion spring assembly line described in this specific embodiment, the following examples are provided.

[0088] Example 1

[0089] This embodiment provides a keyboard torsion spring assembly production line, which includes a conveyor line 1. The conveyor line 1 is equipped with a loading station 11 and an assembly station.

[0090] The assembly station is equipped with a material preparation mechanism 2 and a transverse drive module 3. The material preparation mechanism 2 is used to store and supply torsion springs 7. The transverse drive module 3 drives a transverse plate 31. A longitudinal drive module 32 is installed on the transverse plate 31. The longitudinal drive module 32 drives a longitudinal plate 33. A lifting drive module 34 and an industrial camera 39 are installed on the longitudinal plate 33. The lifting drive module 34 drives a lifting plate 35. A rotation drive mechanism 36 drives a rotating frame 37. A clamp 38 is installed on the rotating frame 37.

[0091] The following is a description of the operation of the keyboard torsion spring assembly line in this embodiment.

[0092] After the loading station 11 loads the keyboard 4, which needs to be fitted with torsion spring 7, onto the conveyor line 1 and transports it to the assembly station, the material preparation mechanism 2 sends out the torsion spring 7. At this time, the transverse drive module 3 drives the transverse plate 31 to move the clamp 38 laterally, the longitudinal drive module 32 drives the longitudinal plate 33 to move the clamp 38 longitudinally, and the lifting drive module 34 drives the lifting plate 35 to lift the clamp 38, so that the clamp 38 can pick up the torsion spring 7 sent out by the material preparation mechanism 2.

[0093] Subsequently, industrial camera 39 is used to acquire the position and orientation of torsion spring 7, and / or the position of mounting position 40 (mounting position 40 refers to the position where keyboard 4 needs to install torsion spring 7); then, lateral drive module 3 again drives lateral plate 31 to move fixture 38 laterally, longitudinal drive module 32 again drives longitudinal plate 33 to move fixture 38 longitudinally, and lifting drive module 34 again drives lifting plate 35 to lift fixture 38, thereby causing fixture 38 to place torsion spring 7 into keyboard 4. Within the mounting position 40; during this period, based on the position and orientation of the torsion spring 7 obtained by the industrial camera 39 and the position of the mounting position 40, the transverse drive module 3 drives the transverse plate 31 to move laterally, or / and the longitudinal drive module 32 drives the longitudinal plate 33 to move longitudinally, or / and the rotation drive mechanism 36 drives the rotating frame 37 to move and / or rotate the fixture 38, so as to move the torsion spring 7 on the fixture 38 (and then precisely adjust the position of the torsion spring 7), thereby installing the torsion spring 7 in the mounting area of ​​the keyboard 4.

[0095] This embodiment provides a keyboard torsion spring assembly production line, which includes a conveyor line 1. The conveyor line 1 is equipped with a feeding station 11 and an assembly station. The assembly station is equipped with a material preparation mechanism 2, a flipping mechanism 6, and a transverse drive module 3.

[0096] The material preparation mechanism 2 is used to store and supply torsion springs 7.

[0097] The flipping mechanism 6 includes a transfer drive module 65 and a base 61. One end of the transfer drive module 65 is located next to the material preparation mechanism 2. The transfer drive module 65 drives a drive block 651 that can be moved away from the material preparation mechanism 2 and close to the fixture 38. The base 61 is mounted on the drive block 651. A flipping seat 62 is connected to the base 61 by a bearing. The top surface of the flipping seat 62 is provided with a placement groove 621 for placing a torsion spring 7. One side of the flipping seat 62 is provided with an arc surface 622 and the other side is provided with a limiting surface 623. An upward push cylinder 63 is installed below the arc surface 622.

[0100] After the loading station 11 loads the keyboard 4, which requires the installation of torsion spring 7, onto the conveyor line 1 and transports it to the assembly station, the preparation mechanism 2 sends out the torsion spring 7 and places it into the placement slot 621 on the base 61.

[0101] Subsequently, the transfer drive module 65 drives the drive block 651, which is located away from the material preparation mechanism 2 and close to the fixture 38; then, the industrial camera 39 acquires the position and orientation of the torsion spring 7, and the push cylinder 63 drives the ball push block 631 to push the flip seat 62 to rotate. The flip seat 62 drives the torsion spring 7 in the placement slot 621 to adjust to an angle that can be installed in the mounting position 40, so that the fixture 38 can pick up the torsion spring 7 after the angle adjustment from the placement slot 621.

[0102] Subsequently, the transverse drive module 3 drives the transverse plate 31 to move the clamp 38 laterally, the longitudinal drive module 32 drives the longitudinal plate 33 to move the clamp 38 longitudinally, and the lifting drive module 34 drives the lifting plate 35 to lift the clamp 38, thereby causing the clamp 38 to clamp the torsion spring 7 in the placement slot 621; then, the push cylinder 63 drives the ball push block 631 to reset, and the tension spring 64 pulls the placement seat to reset. At this time, the limiting surface 623 contacts the base 61.

[0103] Subsequently, industrial camera 39 is used to acquire the position and orientation of torsion spring 7, and / or the position of mounting position 40 (mounting position 40 refers to the position where keyboard 4 needs to install torsion spring 7); then, lateral drive module 3 again drives lateral plate 31 to move fixture 38 laterally, longitudinal drive module 32 again drives longitudinal plate 33 to move fixture 38 longitudinally, and lifting drive module 34 again drives lifting plate 35 to lift fixture 38, thereby causing fixture 38 to place torsion spring 7 into keyboard 4.

[0104] Example 3

[0105] This embodiment provides a keyboard torsion spring assembly line, which includes all the features of Embodiment 1 or 2.

[0106] In addition, the mounting position 40 is provided with a mounting groove 41, the top of the mounting groove 41 is provided with an inclined guide surface 411, and a clearance channel 42 is provided on one side of the mounting groove 41. The bottom end of the clearance channel 42 is provided with a locking block 421, and the top surface of the locking block 421 is provided with an inclined sliding surface 422. The rotating frame 37 is equipped with a first spring 51 and a second spring 52. The first spring 51 pushes a first pressure rod 511, and the second spring 52 pushes a second pressure rod 521. There is a height difference between the first pressure rod 511 and the second pressure rod 521.

[0107] A movable groove 43 is provided on the other side of the mounting groove 41. A limiting part 431 is provided at the top of the movable groove 43, and an outer sliding surface 432 is provided at one corner of the limiting part 431. A third pressure rod 53 is installed on the rotating frame 37. There is a height difference between the third pressure rod 53 and the first pressure rod 511. An outer pushing surface 531 is provided at the bottom of the third pressure rod 53.

[0108] A fixed cylinder 54 is installed on the rotating frame 37. The fixed cylinder 54 drives a fixed pressure rod 541 so that the fixed cylinder 54 drives the fixed pressure rod 541 to press down the fixed keyboard 4 before the first pressure rod 511 presses the spring body into the lowest end of the mounting groove 41.

[0109] The following is a description of the operation of the keyboard torsion spring assembly line described in this embodiment.

[0110] Before the clamp 38 installs the torsion spring 7 in the mounting area of ​​the keyboard 4, the fixing cylinder 54 drives the fixing rod 541 to press down and fix the keyboard 4.

[0111] When the clamp 38 installs the torsion spring 7 into the mounting area of ​​the keyboard 4, the clamp 38 simply places the torsion spring 7 into the mounting position 40. At this time, the inclined guide surface 411 guides the spring body of the torsion spring 7 into the mounting groove 41. Subsequently, the lifting drive module 34 drives the lifting plate 35 to descend, causing the first pressure rod 511 to press the spring body into the lowest end of the mounting groove 41. When the first pressure rod 511 presses the spring body into the lowest end of the mounting groove 41, the lowest end of the mounting groove 41 supports the spring body and restricts its descent, while the spring body prevents the first pressure rod 511 from descending further. At this time, the second pressure rod 521 presses down the first torsion arm 71 of the torsion spring 7 from the clearance channel 42. The first torsion arm 71 passes over the locking block 421 through the inclined sliding surface 422, so that the first torsion arm 71 is locked under the locking block 421. At the same time, the third pressure rod 53 presses down the second torsion arm 72 of the torsion spring 7. The outer push surface 531 of the rod 53 simultaneously pushes the second torsion arm 72 outward, causing the second torsion arm 72 to slide across the outer sliding surface 432 until the outer sliding surface 432 passes the limiting part 431 and enters the movable groove 43. At this time, the second torsion arm 72 can slide in the movable groove 43, finally fixing the torsion spring 7 in the mounting groove 41 and providing support force to the first torsion arm 71 when the torsion force is applied to the torsion spring 7. At the same time, the limiting part 431 restricts the second torsion arm 72 from sliding out of the movable groove 43, thereby completing the installation of the torsion spring 7.
