Description

Technical Field

[0001] This invention relates to the field of automated assembly equipment technology, and in particular to a sheet-like spring feeding and assembly device. Background Technology

[0002] A switch is an electronic component used to control the opening and closing of a circuit. It is a contact mechanism with a small contact interval and a quick-acting mechanism, which performs switching actions with a specified stroke and a specified force. It is covered by a shell and contains multiple conductive elements, such as sheet springs.

[0003] The sheet-like spring is typically stamped from a thin metal sheet and possesses excellent conductivity and elasticity. During assembly, one end of the sheet-like spring needs to be inserted into the first groove of the support plate, while the other end needs to be precisely inserted into the second groove on the conductive frame.

[0004] Traditional assembly involves manually or using multiple machines to assemble the various components, resulting in low assembly efficiency, inconsistent product quality, and low product qualification rates. This is especially true when assembling sheet springs, where the complex movement process and the lack of readily available automated machinery lead to substandard or unqualified assembly, significantly reducing assembly efficiency and product qualification rates. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of low assembly efficiency in the prior art and to provide a sheet spring feeding and assembly device that realizes automatic feeding, precise positioning and efficient assembly of sheet springs, thereby improving assembly efficiency and product qualification rate.

[0006] To achieve the above objectives, the present invention provides a sheet-like spring feeding and assembly device, comprising a frame, a feeding mechanism mounted on one side of the frame for organizing and conveying scattered sheet-like springs to the end; a separating mechanism mounted at the end of the feeding mechanism for precisely positioning the sheet-like springs conveyed to the end and separating adjacent sheet-like springs; an assembly fixture mounted on one side of the separating mechanism for carrying the products to be assembled, and a transfer mechanism correspondingly mounted above the assembly fixture for receiving the sheet-like springs separated by the separating mechanism and transferring them to the working position of the assembly fixture; the transfer mechanism for precisely inserting the sheet-like springs into the support plate and conductive frame.

[0007] Preferably, the feeding mechanism includes a vibratory feeder and a linear feeding track connected to the outlet of the vibratory feeder. The linear feeding track is provided with a conveying groove adapted to the sheet-like spring. The conveying groove extends along the length of the linear feeding track. The sheet-like spring is placed obliquely in the conveying groove. A vibrator is installed at the lower part of the linear feeding track. The vibrator is used to drive the sheet-like spring inside the conveying groove to move orderly along the conveying direction. A pressing block and a pressing cylinder for driving the pressing block are installed at the end of the linear feeding track. The pressing cylinder is used to drive the pressing block to press the sheet-like spring at the end of the linear feeding track. Two first adsorption holes are provided at the end of the linear feeding track. The first adsorption holes are connected to an external vacuum source and are used to sense whether the sheet-like spring is in place.

[0008] Preferably, the material separating mechanism includes a mounting plate installed at the end of a linear feeding track. The mounting plate contains a separating block with a receiving groove matching the shape of the sheet-like spring and is connected to the end of the linear feeding track. The receiving groove has a second adsorption hole connected to an external vacuum source to sense whether the sheet-like spring is in position. A first longitudinal cylinder is installed at one end of the mounting plate to drive the separating block to move longitudinally on the mounting plate to separate the sheet-like spring.

[0009] Preferably, the material separating mechanism further includes a first transverse cylinder mounted on the frame. The output end of the first transverse cylinder is connected to the mounting plate and is used to drive the first longitudinal cylinder, the mounting plate, the separating block and the separated sheet-like springs to move laterally and transfer the separated sheet-like springs laterally to the lower part of the transfer mechanism.

[0010] Preferably, the transfer mechanism includes a transfer rod with a suction nozzle groove at its lower end for picking up sheet-like spring pieces. The suction nozzle groove has a third suction hole connected to an external vacuum source for adsorbing the upper surface of the sheet-like spring pieces. The transfer mechanism also includes a second horizontal cylinder mounted on the frame and a first vertical module mounted on the output end of the second horizontal cylinder. The first vertical module is driven by the transfer rod, driving the transfer rod to move vertically to cooperate with the suction nozzle groove to pick up the sheet-like spring pieces. The second horizontal cylinder is driven by the first vertical module, driving the first vertical module and the transfer rod to move horizontally together, transferring the sheet-like spring pieces from the material distribution mechanism to the upper part of the assembly fixture.

[0011] Preferably, the second transverse cylinder is equipped with a transverse moving plate at its end. A first vertical module is installed on one side of the transverse moving plate, and a guide block is installed on the other side. The guide block has a guide groove inside, which includes a vertical guide section and an inclined guide section. The first vertical module includes a drive motor installed on the upper part of the transverse moving plate. The output end of the drive motor is connected to a lead screw. The lead screw is threadedly engaged with a vertical slider sleeved on the lead screw. The vertical slider is connected to the transfer rod in a transmission connection.

[0012] Preferably, the vertical slider is equipped with an inclined guide rail, and the inclined slider is fitted on the inclined guide rail. The inclined slider is adapted to the inclined guide section. A transfer rod is installed on one side of the inclined slider and a guide wheel is installed on the other side. The guide wheel slides through the guide groove, thereby guiding the inclined slider and the transfer rod to move along a predetermined trajectory during the vertical descent, so that one end of the sheet-like spring moves closer to the first groove on the support plate.

[0013] Preferably, the vertical slider is equipped with a first receiving block, the inclined slider is equipped with a second receiving block, and an inclined spring is inclinedly installed between the first receiving block and the second receiving block. The inclined spring is used to provide a restoring force to ensure that the guide wheel is always tightly attached to the inner wall of the guide groove.

[0014] Preferably, the tilting slider is equipped with a tilting cylinder, the output end of which is equipped with a tilting rod. The end of the tilting rod is provided with a receiving groove that corresponds to one end of the sheet-like spring. The tilting cylinder drives the tilting rod to tilt, pushing the sheet-like spring to slide precisely into the first groove of the support plate along the tilting trajectory. The tilting slider is also equipped with a first vertical cylinder, the output end of which is connected to the transfer rod and is used to drive the transfer rod to move vertically. The first vertical cylinder drives the transfer rod and the sheet-like spring to move vertically downward, so that the end of the sheet-like spring away from the support plate is inserted into the second groove on the conductive frame.

[0015] Preferably, the assembly fixture includes a fixture base plate, an inclined positioning block mounted on one side of the fixture base plate for tilting the conductive frame, and a first positioning block mounted on the other side of the fixture base plate for positioning the bent connector. The fixture base plate has a first placement groove for placing the support plate, and the inclined positioning block has a second placement groove that matches the conductive frame. A second positioning block for positioning one side of the conductive frame is mounted on one side of the second placement groove, and a third positioning block for positioning the other side of the conductive frame is mounted on the other side. The lower parts of the second and third positioning blocks are driven by driving claws, and the driving claws are connected to driving components for clamping or releasing the conductive frame. The lower part of the second positioning block has a clearance groove for avoiding the support plate. A second spring for providing elastic clamping force is installed between the ends of the second and third positioning blocks and the ends of the fixture base plate. The ends of the second and third positioning blocks near the conductive frame have positioning protrusions that are adapted to the conductive frame. The positioning protrusions cooperate with the positioning grooves on the conductive frame to ensure that the conductive frame maintains a precise position on the inclined positioning block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The assembly process of this invention involves the following steps: First, multiple sheet-like spring pieces are placed inside a feeding mechanism. The feeding mechanism organizes the scattered sheet-like spring pieces and transports them in an orderly manner to the end. The sheet-like spring pieces at the end are output one by one in a horizontal arrangement. The sheet-like spring pieces at the end enter a sorting mechanism for precise positioning and separation of adjacent sheet-like spring pieces. Second, an assembly fixture is installed on one side of the sorting mechanism. The assembly fixture is used to carry the product to be assembled. The product to be assembled carried by the assembly fixture includes a support plate, a conductive frame, and a bent connector, all of which are pre-positioned. On the base plate of the fixture, the sheet-shaped springs are automatically conveyed to the side of the material distribution mechanism. Next, the transfer mechanism connects with the material distribution mechanism, picking up the distributed sheet-shaped springs from the material distribution mechanism and transferring them to the top of the assembly fixture, where they enter the working station inside the assembly fixture. Finally, the transfer mechanism precisely inserts the sheet-shaped springs into the support plate and the conductive frame, with one end of the sheet-shaped spring inserted into the first groove on the support plate and the other end inserted into the second groove on the conductive frame, completing the stable assembly of the sheet-shaped springs with the support plate, the conductive frame, and the bending connector. This invention, through the above structural design and motion control, achieves automatic feeding, precise positioning, and efficient assembly of sheet-shaped springs, improving assembly efficiency and product qualification rate.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are one embodiment of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please refer to Figures 1 to 15 The present invention provides a sheet-like spring feeding and assembly device.

[0038] like Figure 3As shown, the assembly device is divided into three parts. The first part is the feeding mechanism 2 and the dispensing mechanism 4 mounted on the frame. The second part is the assembly fixture 5 located on the other side. The assembly fixture 5 can be driven by an assembly line. The products to be assembled carried by the assembly fixture 5 include a support plate 32, a conductive frame 33, and a bent connector 34. The third part is the transfer mechanism 6 mounted on top, covering the dispensing mechanism 4 and the assembly fixture 5. The transfer mechanism 6 is used to transfer the sheet-like springs 31 on the dispensing mechanism 4 to the assembly fixture 5 for assembly.

[0039] Specifically, the assembly device includes a frame 1, on the left side of which is a feeding mechanism 2. The feeding mechanism 2 is used to accommodate multiple randomly arranged sheet-like spring pieces 31 and to vibrate and organize them, so that the sheet-like spring pieces 31 are arranged in an orderly manner for output. The output method is to output them one by one to a sorting mechanism 4. The sorting mechanism 4 is located at the end of the feeding mechanism 2, which naturally and precisely positions the sheet-like spring pieces 31 and separates adjacent sheet-like spring pieces 31, thereby facilitating subsequent transfer and not interfering with the feeding mechanism 2. The material distribution mechanism 4 is equipped with an assembly fixture 5 on one side. The assembly fixture 5 is used to carry the products to be assembled. The products to be assembled carried by the assembly fixture 5 include a support plate 32, a conductive frame 33, and a bent connector 34. A transfer mechanism 6 is provided above the assembly fixture 5. The transfer mechanism 6 is used to receive the sheet-like spring pieces 31 after being distributed by the material distribution mechanism 4 and transfer them to the working position of the assembly fixture 5. The transfer mechanism 6 is used to accurately insert the sheet-like spring pieces 31 into the support plate 32 and the conductive frame 33. The assembly fixture 5 transports and positions the support plate 32, the conductive frame 33, and the bending connector 34. The transfer mechanism 6 inserts one end of the sheet-like spring 31 into the first groove 321 of the support plate 32 and the other end into the second groove 331 of the conductive frame 33, thus completing the assembly of the sheet-like spring 31, the support plate 32, the conductive frame 33, and the bending connector 34. The assembly fixture 5 then continues to move along the assembly line to the next station for subsequent processes.

[0040] like Figure 4As shown, the feeding mechanism 2 includes a vibratory feeder 21 and a linear feeding track 22 connected to the outlet of the vibratory feeder 21. The linear feeding track 22 is arranged laterally to convey and output the sheet-like spring pieces 31 laterally. The linear feeding track 22 is provided with a conveying groove 23 adapted to the sheet-like spring pieces 31. The conveying groove 23 extends along the length of the linear feeding track 22 and is inclined so that the sheet-like spring pieces 31 are placed inclinedly in the conveying groove 23. The upper part of the sheet-like spring pieces 31 has a certain curvature and adapts to the conveying groove 23, so that the sheet-like spring pieces 31 are placed stably and will not slip under the action of gravity. The linear feeding track 2... 2. A vibrator 24 is installed at the lower part. The vibrator 24 is used to drive the sheet-like springs 31 inside the conveying groove 23 to move orderly along the transverse conveying direction. In order to keep the sheet-like springs 31 stable at the end during the conveying process, a pressing block 25 and a pressing cylinder 26 for driving the pressing block 25 are installed at the end of the linear feeding track 22. The pressing cylinder 26 is used to drive the pressing block 25 to press the sheet-like springs 31 at the end of the linear feeding track 22. When conveying is not required, the pressing block 25 presses down the sheet-like springs 31 to prevent further conveying. When conveying is required, the pressing cylinder 26 drives the pressing block 25 to lift up and release the sheet-like springs 31, which then enter the dispensing mechanism 4. Furthermore, the pressing block 25 has a pressing rubber layer at its end to avoid damaging the surface of the sheet-like springs 31 when pressing.

[0041] To sense whether the sheet-like spring 31 at the end is in position, the linear feeding track 22 has two first adsorption holes 27 arranged side by side at its end. The first adsorption holes 27 are connected to an external vacuum source and are used to sense whether the sheet-like spring 31 is in position. When the sheet-like spring 31 covers the first adsorption hole 27, the vacuum pressure signal changes. Based on this, the control system determines that the sheet-like spring 31 has accurately reached the predetermined position, and then controls the pressing cylinder 26 to drive the pressing block 25 to press down, so as to fix the sheet-like spring 31 and prevent it from shifting during the subsequent separation process. At the same time, the material distribution mechanism 4 located below the end of the linear feeding track 22 starts to operate, preparing to distribute the sheet-like spring 31 inside the receiving tank 42.

[0042] During the conveying process, the control system will determine that the sheet-like spring 31 is in place only when there is a sheet-like spring 31 inside the receiving tank 42 and the first suction hole 27 is covered again, and then start the pressing cylinder 26 and the dispensing mechanism 4 to operate in sequence.

[0043] like Figure 7 and Figure 8As shown, the material distribution mechanism 4 includes a mounting plate 46 installed at the end of the linear feeding track 22. The mounting plate 46 is equipped with a separation block 41. The separation block 41 is provided with a receiving groove 42 that matches the shape of the sheet-like spring 31 and is connected to the end of the linear feeding track 22.

[0044] The receiving groove 42 has a blocking protrusion on the side away from the linear feeding track 22 to prevent the sheet-like spring 31 from moving laterally. To fix the sheet-like spring 31 inside the receiving groove 42, a second adsorption hole 43 is provided on the receiving groove 42. The second adsorption hole 43 is connected to an external vacuum source and is used to sense whether the sheet-like spring 31 is in position, and can also adsorb and fix the sheet-like spring 31 inside the receiving groove 42 to prevent it from shifting or falling off during subsequent transfer. After the sheet-like spring 31 is adsorbed and fixed, a first longitudinal cylinder 44 is installed at one end of the mounting plate 46. The first longitudinal cylinder 44 is used to drive the separating block 41 to move longitudinally on the mounting plate 46, separating the sheet-like spring 31.

[0045] Furthermore, in order to be closer to the transfer mechanism 6 and the assembly fixture 5, the material distribution mechanism 4 also includes a first transverse cylinder 45 mounted on the frame 1. The output end of the first transverse cylinder 45 is connected to the mounting plate 46 and is used to drive the first longitudinal cylinder 44, the mounting plate 46, the separating block 41 and the separated sheet-like spring 31 to move laterally, so as to laterally transfer the separated sheet-like spring 31 to the lower part of the transfer mechanism 6.

[0046] At this time, the transfer rod 61 of the transfer mechanism 6 descends, and the sheet-like spring 31 in the receiving groove 42 is taken out by vacuum adsorption and transferred to the assembly fixture 5 for subsequent assembly operations.

[0047] like Figure 10 As shown, the transfer mechanism 6 includes a transfer rod 61. The lower end of the transfer rod 61 is provided with a suction nozzle groove 62 for picking up the sheet-like spring 31. The suction nozzle groove 62 is provided with a third suction hole 63. The third suction hole 63 is connected to an external vacuum source and is used to pick up the upper surface of the sheet-like spring 31 and remove the sheet-like spring 31 from the receiving groove 42.

[0048] The third adsorption hole 63 also has a positioning detection function. When the transfer rod 61 descends above the receiving groove 42, if the third adsorption hole 63 is covered by the sheet-like spring 31, the system determines that the sheet-like spring 31 has been successfully adsorbed, and then controls the second adsorption hole 43 to stop sucking air. At the same time, the transfer rod 61 rises and moves the sheet-like spring 31 to the top of the assembly fixture 5.

[0049] To achieve the lateral and vertical movement of the transfer rod 61, the transfer mechanism 6 further includes a second lateral cylinder 64 mounted on the frame 1 and a first vertical module 65 mounted on the output end of the second lateral cylinder 64. The first vertical module 65 is convexly connected to the transfer rod 61, driving the transfer rod 61 to move vertically to cooperate with the suction nozzle groove 62 to pick up the sheet-like spring 31. The second lateral cylinder 64 is indirectly convexly connected to the transfer rod 61 through the first vertical module 65, driving the first vertical module 65 and the transfer rod 61 to move laterally together, transferring the sheet-like spring 31 from the material distribution mechanism 4 to the upper part of the assembly fixture 5.

[0050] Specifically, the second transverse cylinder 64 is mounted on the frame 1, and its output end is equipped with a transverse moving plate 641. In order to accurately control the transverse moving plate 641, multiple transverse guide rails and transverse sliders can be mounted on the frame 1. The transverse sliders are mounted on the back of the transverse moving plate 641 and slide in cooperation with the transverse guide rails, thereby indirectly ensuring that the transfer rod 61 remains stable during transverse movement.

[0051] Furthermore, a first vertical module 65 is installed on one side of the transverse moving plate 641, and a guide block 642 is installed on the other side. The guide block 642 has a guide groove 643 inside, which includes a vertical guide section 644 and an inclined guide section 645. The transfer rod 61 moves along the guide groove 643. When the transfer rod 61 is in the vertical guide section 644, it makes a vertical lifting motion to complete the adsorption action. When the transfer rod 61 enters the inclined guide section 645, its movement trajectory gradually tilts, so that the sheet-like spring 31 realizes a combination of vertical and longitudinal movement during the transfer process, thereby making the sheet-like spring 31 gradually approach the first groove 321 on the support plate 32.

[0052] In order to achieve the adsorption of the sheet-like spring 31 in the vertical guide section 644, the vertical height of the feeding mechanism 2 and the distributing mechanism 4 can be reasonably set so that when the transfer rod 61 is at the end of the vertical guide section 644, its suction nozzle groove 62 is exactly above the receiving groove 42, and the third adsorption hole 63 is tightly attached to the upper surface of the sheet-like spring 31, thereby ensuring the reliability of adsorption.

[0053] like Figure 9As shown, the first vertical module 65 includes a drive motor 652 mounted on the upper part of the horizontal moving plate 641. The output end of the drive motor 652 is connected to a lead screw 653. The lead screw 653 is threadedly engaged with a vertical slider 654 sleeved on the lead screw 653. The vertical slider 654 is connected to the transfer rod 61 via a transmission connection. The drive motor 652 drives the vertical slider 654 to move up and down via the lead screw 653, thereby precisely controlling the vertical displacement of the transfer rod 61. Using the first vertical module 65 enables the vertical adsorption of the sheet-like spring 31, facilitating the control of the accuracy and stability of vertical movement, and also enabling the adsorption of sheet-like springs 31 of various specifications.

[0054] To ensure the smoothness and guiding accuracy of the tilting motion, an inclined guide rail 656 is installed on the vertical slider 654, and an inclined slider 657 is fitted on the inclined guide rail 656. The inclined slider 657 is adapted to the inclined guide section 645. A transfer rod 61 is installed on one side of the inclined slider 657, and a guide wheel 655 is installed on the other side. The guide wheel 655 slides through the guide groove 643, thereby guiding the inclined slider 657 and the transfer rod 61 to move along a predetermined trajectory during the vertical descent, so that one end of the sheet-like spring 31 moves closer to the first groove 321 on the support plate 32, realizing the combination of vertical and longitudinal motion of the sheet-like spring 31.

[0055] Through the above structural design, after the transfer rod 61 completes adsorption in the vertical guide section 644, when it enters the inclined guide section 645, the guide wheel 655 moves along the inclined section of the guide groove 643, driving the transfer rod 61 to move vertically and longitudinally in a combined motion, so that the sheet-like spring 31 gradually approaches the first groove 321; the longitudinal movement structure is reduced, the cost is reduced, and the transfer process of the sheet-like spring 31 is made more stable and efficient.

[0056] To ensure close contact between the guide wheel 655 and the guide groove 643 and achieve precise motion guidance, a first receiving block 658 is mounted on the vertical slider 654, and a second receiving block 659 is mounted on the inclined slider 657. An inclined spring 650 is inclinedly mounted between the first receiving block 658 and the second receiving block 659. The inclined spring 650 is used to provide a restoring force to ensure that the guide wheel 655 is always in close contact with the inner wall of the guide groove 643, thereby eliminating motion gaps and improving guidance accuracy and motion stability.

[0057] When the transfer rod 61 completes the installation of the sheet spring 31 and returns, the tilting spring 650 releases its restoring force, pushing the tilting slider 657 to slide in the opposite direction along the tilting guide rail 656. This causes the guide wheel 655 to move in the opposite direction along the tilted section of the guide groove 643, smoothly returning the transfer rod 61 to the vertical guide section 644, preparing it for the next adsorption action. Through the elastic restoring mechanism of the tilting spring 650, continuous and close contact between the guide wheel 655 and the guide groove 643 is achieved, ensuring the consistency of the transfer rod 61's trajectory during reciprocating motion, thereby improving the installation accuracy and repeatability of the sheet spring 31.

[0058] In order to achieve automated insertion of the sheet-like spring 31, the tilting slider 657 is equipped with a tilting cylinder 81, and the output end of the tilting cylinder 81 is equipped with a tilting rod 82. In this embodiment, the tilting rod 82 is used to push the sheet-like spring 31 into the first groove 321 until the end of the sheet-like spring 31 is completely inserted into the first groove 321.

[0059] Furthermore, the end of the tilting rod 82 is provided with a receiving groove 83 that is adapted to one end of the sheet-like spring 31. The tilting cylinder 81 drives the tilting rod 82 to tilt, pushing the sheet-like spring 31 to slide precisely into the first groove 321 of the support plate 32 along the tilting trajectory.

[0060] Through the aforementioned movements, one end of the sheet-like spring 31 has been inserted. The other end needs to be inserted through vertical movement. Specifically, the inclined slider 657 is also equipped with a first vertical cylinder 84. The output end of the first vertical cylinder 84 is connected to the transfer rod 61, which is used to drive the transfer rod 61 to move vertically. The transfer rod 61 moves inside the inclined slider 657, thereby limiting its movement and ensuring the stability of the vertical movement. The first vertical cylinder 84 drives the transfer rod 61 and the sheet-like spring 31 to move vertically downward, so that the end of the sheet-like spring 31 away from the support plate 32 is inserted into the second groove 331 on the conductive frame 33. Through the above-mentioned linkage action, both ends of the sheet-like spring 31 are inserted into the first groove 321 and the second groove 331 respectively, thereby completing the reliable installation of the sheet-like spring 31 between the support plate 32 and the conductive frame 33. This design achieves precise insertion of the sheet-like spring 31 in confined spaces through the coordinated operation of tilting and vertical movements, avoiding installation interference problems caused by space limitations. Simultaneously, the timing control of the tilting cylinder 81 and the first vertical cylinder 84 ensures the sequential order and positional accuracy of the insertion actions at both ends of the sheet-like spring 31, further improving the installation success rate and consistency of the sheet-like spring 31.

[0061] like Figure 14 and Figure 15As shown, the assembly fixture 5 includes a fixture base plate 51, an inclined positioning block 52 mounted on one side of the fixture base plate 51 for tilting the conductive frame 33, and a first positioning block 53 mounted on the other side of the fixture base plate 51 for positioning the bent connector 34. The fixture base plate 51 is provided with a first placement groove 511 for placing the support plate 32. In order to completely limit the conductive frame 33, the inclined positioning block 52 is provided with a second placement groove 521 that matches the conductive frame 33. Furthermore, a positioning conductive frame is mounted on one side of the second placement groove 521. A second positioning block 522 is provided on one side of the conductive frame 33, and a third positioning block 523 is provided on the other side for positioning the other side of the conductive frame 33. In order to ensure that the conductive frame 33 is fixed, the second positioning block 522 and the third positioning block 523 are provided with positioning protrusions 527 that are adapted to the conductive frame 33 at the end near the conductive frame 33. The positioning protrusions 527 cooperate with the positioning grooves 332 on the conductive frame 33. When fixing, the positioning protrusions 527 are inserted into the positioning grooves 332 to ensure that the conductive frame 33 maintains a precise position on the inclined positioning block 52.

[0062] In practice, in order to avoid the support plate 32, the second positioning block 522 is provided with an avoidance groove 525 at the bottom to avoid the support plate 32. When the second positioning block 522 moves laterally and is inserted into the conductive frame 33, the avoidance groove 525 can effectively avoid the interference area of ​​the support plate 32, and at the same time limit the support plate 32 so that it is stably placed in the first placement groove 511.

[0063] like Figure 15 As shown, in order to realize the lateral movement of the second positioning block 522 and the third positioning block 523 and to achieve quick clamping and releasing, the lower part of the second positioning block 522 and the third positioning block 523 are connected to a driving claw 524. One end of the driving claw 524 is inserted into the driving groove at the bottom of the second positioning block 522 or the third positioning block 523. The driving claw 524 is connected to a driving component to drive the second positioning block 522 and the third positioning block 523 to move laterally, so as to realize the quick clamping and releasing operation of the conductive frame 33. The drive claw 524 can be connected to a standard drive source such as a cylinder, motor, or manual push rod. By controlling the rotational movement of the drive claw 524, the synchronous clamping and release of the second positioning block 522 and the third positioning block 523 can be achieved. In this embodiment, the drive claw 524 is hinged to the fixture base plate 51. When the distance between the drive claws 524 is reduced, the distance at the top of the drive claw 524 increases, and the second positioning block 522 and the third positioning block 523 are synchronously relaxed. When the distance between the drive claws 524 is increased, the distance at the top of the drive claw 524 decreases, and the second positioning block 522 and the third positioning block 523 are synchronously clamped, thereby firmly fixing the conductive frame 33 on the inclined positioning block 52.

[0064] To ensure that the assembly fixture 5 maintains a clamping state on the conductive frame 33 when it leaves the driving component, a second spring 526 is installed between the ends of the second positioning block 522 and the third positioning block 523 and the end of the fixture base plate 51 to provide elastic clamping force. After leaving the driving component, the second positioning block 522 and the third positioning block 523 maintain a clamping state on the conductive frame 33 under the action of the second spring 526. The second spring 526 is sleeved between the fixture base plate 51 and the second positioning block 522, and between the fixture base plate 51 and the third positioning block 523. One end of the second spring 526 abuts against the side wall of the fixture base plate 51, and the other end abuts against the side wall of the second positioning block 522 or the third positioning block 523. After leaving the driving component, the elastic force of the second spring 526 will push the second positioning block 522 and the third positioning block 523 to move inward, thereby maintaining continuous clamping of the conductive frame 33, ensuring that the conductive frame 33 will not be displaced or loosened when being transported or waiting for the next process, thus improving the stability and reliability of the assembly process.

[0065] Through the above structural design, the assembly fixture 5 can simultaneously achieve precise positioning of the support plate 32, the conductive frame 33, and the bending connector 34, providing a stable foundation for the subsequent automated installation of the sheet-like spring 31.

[0066] The assembly process:

[0067] First, the assembly fixture 5 transports the support plate 32, the conductive frame 33, and the bending connector 34. One end of the bending connector 34 is inserted into the support plate 32, and the conductive frame 33 is placed on the assembly of the bending connector 34 and the support plate 32. Then, all three components are placed inside the assembly fixture 5. Specifically, the assembly is placed inside the groove formed by the first positioning block 53, the first placement groove 511, and the second placement groove 521. The conductive frame 33 is then fixed inside the second placement groove 521. The bracket plate 32 is placed inside the first placement groove 511. The first positioning block 53 positions the bent connector 34. The second positioning block 522 and the third positioning block 523, driven by the second spring 526, insert the positioning protrusion 527 into the positioning groove 332. This ensures that the conductive frame 33 maintains a precise position on the inclined positioning block 52 and also fixes the three-part assembly. The second positioning block 522 is provided with an avoidance groove 525, which can limit the bracket plate 32 and make it stably placed in the first placement groove 511.

[0068] Secondly, the assembly fixture 5 and the three-in-one assembly are conveyed together via a conveyor line to one side of the material distribution mechanism 4. The sheet-like springs 31 are placed inside the vibratory feeder 21, which outputs the sheet-like springs 31 in a timely manner, arranging them orderly on the conveying groove 23. The lower vibrator 24 drives the sheet-like springs 31 inside the conveying groove 23 to move orderly along the transverse conveying direction until they are conveyed to the end and into the receiving groove 42. When the first suction hole 27 and the second suction hole 43 are covered and the sheet-like springs 31 are sensed, the pressing cylinder 26 drives the pressing block 25 to press down, fixing the sheet-like springs 31 at the end of the linear feeding track 22. The first longitudinal cylinder 44 drives the separating block 41 to move longitudinally, separating the sheet-like springs 31. The first transverse cylinder 45 drives the separating block 41 to move laterally, moving the separated sheet-like springs 31 and the separating block 41 laterally to the side close to the assembly fixture 5.

[0069] Next, the second horizontal cylinder 64 drives the first vertical module 65 and the transfer rod 61 to move laterally together. The first vertical module 65 drives the transfer rod 61 to move vertically under the guidance of the vertical guide section 644, so that when the transfer rod 61 is at the end of the vertical guide section 644, its suction nozzle groove 62 is exactly above the receiving groove 42, and the third suction hole 63 is tightly attached to the upper surface of the sheet-like spring 31, adsorbing the sheet-like spring 31 and transferring the sheet-like spring 31 from the material distribution mechanism 4 to the upper part of the assembly fixture 5.

[0070] Finally, the first vertical module 65 drives the transfer rod 61 to move vertically downward under the guidance of the vertical guide section 644. Under the guidance of the inclined guide section 645, one end of the sheet-like spring 31 moves closer to the first groove 321 on the support plate 32, realizing the combination of vertical and longitudinal movement of the sheet-like spring 31. After completing the above actions, the inclined cylinder 81 drives the inclined rod 82 to push the sheet-like spring 31 at the end of the transfer rod 61 to tilt. Without detaching from the end of the transfer rod 61, the end of the sheet-like spring 31 is fully inserted into the first groove 321. The first vertical cylinder 84 drives the transfer rod 61 and the sheet-like spring 31 to move vertically downward, so that the end of the sheet-like spring 31 away from the support plate 32 is inserted into the second groove 331 on the conductive frame 33. The third adsorption hole 63 at the end of the transfer rod 61 does not generate a vacuum, thus separating from the sheet-like spring 31, thereby completing the automatic assembly of the sheet-like spring 31.
