Description

Technical Field

[0001] The present invention relates to an automated assembly production equipment, and more particularly to a product base spring sheet assembly-wax sealing production line. Background Art

[0002] Figure 1 and Figure 2 A plastic base 1 for electronic products such as smoke alarms has a spring mounting portion 1-1 on its inner bottom. A spring 1-2 is typically secured to the spring mounting portion 1-1 using screws. To secure the screws, a nut slot 1-3 is provided at a corresponding position on the back of the plastic base 1. A nut is pre-embedded within the nut slot 1-3, tightening the screw and nut to secure the spring 1-2. To prevent the exposed nut from rusting, the nut slot 1-3 is sealed with wax after installation. To this end, a ridge is provided around the outer periphery of the nut slot 1-3, forming a wax-sealing cavity 1-4.

[0003] With the rapid development of automation technology, and because manual assembly is extremely inefficient and difficult to guarantee quality, automated equipment has replaced manual assembly for most products of this type. However, due to the small size of the springs being assembled, and the fact that the springs and nuts need to be assembled on two different sides of the product, the following issues still need to be addressed during the automation process:

[0004] 1) Most of the aforementioned plastic base products are circular in structure. Since there is no self-positioning structure on their outer periphery, the problem of product positioning must be overcome during the automatic loading process to ensure that the product flows through each assembly station at a set angle.

[0005] 2) The spring sheet and nut are on different assembly surfaces, and the embedded nut needs to be installed from the back of the product. Compared with the front-mounted nut structure, the difficulty of back-mounted nut is that the space at the bottom of the product is limited, and the feeding and press-fitting structure design of the nut is greatly restricted, which brings certain technical difficulties to the automated assembly of the nut;

[0006] 3) The spring sheet is small in size, and the requirements for the grasping and assembly accuracy of the spring sheet are high. In terms of mechanism design, it is necessary to ensure both the compactness of the structure and the high precision of the assembly action. This is also one of the design difficulties of the automatic assembly of the spring sheet;

[0007] 4) After the spring sheet is installed, the product needs to be turned over to the back for wax sealing. This requires the part to be turned over to achieve automated operation on both the front and back assembly surfaces. However, there is no special turning mechanism for similar parts in the existing technology. Summary of the Invention

[0008] 1. Technical problem to be solved by the invention

[0009] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a product base spring sheet assembly-wax sealing production line. By adopting the technical solution of the present invention, the product is positioned and conveyed by a product feeding mechanism, and the spring sheet is assembled in sequence using a nut assembly mechanism, a spring sheet assembly mechanism and a screw assembly mechanism, and the product is turned over and then wax sealed by a product turning mechanism.

[0069] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0070] [Example]

[0071] Combine Figure 3As shown, a product base spring sheet assembly-wax sealing production line of this embodiment includes a product loading mechanism 100, a product conveying track 200, a nut assembly mechanism 300, a spring sheet assembly mechanism 400, a screw assembly mechanism 500, a product flipping mechanism 600 and a wax sealing mechanism 700. The product loading mechanism 100 is connected to one end of the product conveying track 200, and the other end of the product conveying track 200 is connected to the wax sealing mechanism 700 through the product flipping mechanism 600. The nut assembly mechanism 300, the spring sheet assembly mechanism 400 and the screw assembly mechanism 500 are arranged in sequence along the product conveying track 200, and the nut assembly mechanism 300 is located on the side close to the product loading mechanism 100. Products are positioned and conveyed by the product loading mechanism 100 onto the product conveyor track 200. They then circulate through various assembly stations on the product conveyor track 200, passing through the nut assembly mechanism 300 where a pre-embedded nut is press-fitted onto the back of the product, the spring assembly mechanism 400 where a spring is installed onto the front of the product, and the screw assembly mechanism 500 where screws are installed. The spring is then secured to the product by tightening the screws and pre-embedded nuts. The product then passes through the product flipping mechanism 600 where it is flipped 180° and then enters the wax sealing mechanism 700 where wax is injected, completing the entire spring assembly and wax sealing process. The entire production line assembly process is compact and orderly, significantly improving production efficiency. The automated assembly process also provides consistent quality and high assembly quality.

[0072] Reference Figures 4 to 7As shown, the product loading mechanism 100 in this embodiment includes a storage bin 13, a discharging mechanism 16 and a discharging plate 18. The storage bin 13 is arranged above the loading frame 11 and is used to stack products stacked together. The discharging mechanism 16 is located on one side of the storage bin 13. The discharging plate 18 is connected to the discharging mechanism 16. The discharging mechanism 16 is used to convey the products in the storage bin 13 to the discharging plate 18 one by one. The upper surface of the discharging plate 18 is provided with a positioning groove 18-1 extending along the horizontal conveying direction of the product.

In the pallet cavity 18-2 just below the discharging mechanism 16, a rotating pallet 16-10 with controlled rotational movement is provided in the pallet cavity 18-2, and a sensor 16-11 for detecting the positioning position of the product on the rotating pallet 16-10 is provided near the rotating pallet 16-10; the product falls on the rotating pallet 16-10, and the rotating pallet 16-10 drives the product to rotate to the set angle, and then transports it to the discharging plate 18 to realize the rotational positioning of the product. After rotational positioning, the product is output at the set angle in the positioning groove 18-1 on the discharging plate 18, which solves the problem of easy rotational deviation during product loading, greatly improves the stability of the product assembly and feeding action, and helps to ensure the normal operation of subsequent assembly processes. The above-mentioned discharge plate 18 is connected to the product conveying track 200, and the product conveying track 200 has a guide groove 201 opposite to the above-mentioned positioning groove 18-1. The product output by the product loading mechanism 100 can flow at a set angle under the limiting action of the guide groove 201, which is convenient for stable assembly of subsequent workstations.

The side-shifting conveying mechanism 15 is located on one side of the storage bin 13. The whole-pushing mechanism 14 has a pushing plate 14-6 located opposite the side-shifting conveying mechanism 15 and controlled to move toward the side-shifting conveying mechanism 15. The whole-pushing mechanism 14 is used to push the stacked products in the storage bin 13 toward the side-shifting conveying mechanism 15, and the side-shifting conveying mechanism 15 conveys one row of the stacked products to one side. A discharge mechanism 16 is provided at the discharge end of the side-shifting conveying mechanism 15. By utilizing the whole-pushing mechanism 14 and the side-shifting conveying mechanism 15 to transport and transfer the stacked products in the storage bin 13, the storage bin 13 can store a large amount of products at a time, reducing the frequency of manual repeated loading and improving the level of automation. Furthermore, the above-mentioned discharging mechanism 16 includes a discharging baffle 16-1, a blanking plate 16-2, a blocking drive 16-3, a receiving drive 16-5, a lifting seat 16-6, a servo rotation drive 16-8 and a discharging drive 16-9. The discharging baffle 16-1 is arranged at the discharging end of the side-shift conveying mechanism 15, and is surrounded by a stacked product discharging channel on one side of the storage bin 13, for realizing the positioning of a stack of products conveyed by the side-shift conveying mechanism 15; the blanking plate 16-2 is located below the discharging baffle 16-1, and is provided with a blanking hole 16-2a located below the stacked product discharging channel on the blanking plate 16-2. The shape of the blanking hole 16-2a is adapted to the outer contour of the product. For example, a circular blanking hole 16-2a can be used for a circular product; the blanking plate 16-2 is provided with at least one stopper 16-3a which can move radially telescopically in the blanking hole 16-2a to block the material. Block 16-3a is transmission connected to the material blocking driver 16-3, and the material blocking driver 16-3 controls the movement of the block 16-3a, and the clamping or release of the product entering the blanking hole 16-2a is achieved through the telescopic movement of the block 16-3a; the material receiving driver 16-5 is fixedly installed on the frame, and the driving end of the material receiving driver 16-5 is connected to the lifting seat 16-6, and the rotating shaft of the rotating pallet 16-10 is transmission connected to the output shaft of the servo rotary driver 16-8. The servo rotary driver 16-8 is installed on the lifting seat 16-6 and is used to drive the rotating pallet 16-10 to move up and down in the pallet cavity 18-2; the discharging driver 16-9 is arranged on the opposite side of the horizontal conveying direction of the discharging plate 18, and the discharging driver 16-9 has a telescopic pushing part located in the discharging gap between the blanking plate 16-2 and the discharging plate 18 and toward the horizontal conveying direction of the discharging plate 18.During operation, the receiving driver 16-5 drives the rotating pallet 16-10 to rise to the lower portion of the blanking hole 16-2a. The stopping driver 16-3 drives the stopper 16-3a to retract, releasing the products in the stacked product discharge channel and causing them to fall onto the rotating pallet 16-10. The servo rotary driver 16-8 then drives the rotating pallet 16-10 to rotate, and the sensor 16-11 detects the angular position of the bottom product. The sensor 16-11 determines the part angle by identifying the raised structure on the product. When the bottom product reaches the set angle, the stopping driver 16-3 drives the stopper 16-3a to push out, clamping the second-to-last product. At this time, the receiving driver 16-5 drives the rotating pallet 16-10 to descend, so that the bottom surface of the bottom product is at the same height as the discharge plate 18. The discharge driver 16-9 then pushes the bottom product onto the discharge plate 18. Repeating these steps, the products can be transported to the discharge plate 18 one by one and arranged along the length of the discharge plate 18. The servo rotary driver 16-8 is preferably a servo motor, and the sensor 16-11 is preferably a photoelectric sensor. The material blocking driver 16-3, the material receiving driver 16-5 and the material discharging driver 16-9 are preferably telescopic cylinders.

Preferably, two of the above-mentioned stops 16-3a are arranged opposite to each other on both sides of the blanking hole 16-2a of the blanking plate 16-2, and each stop 16-3a is connected to a stop driver 16-3 for transmission. The stop driver 16-3 is fixed to the side wall of the blanking plate 16-2 through a support plate 16-3b. The clamping and release of the product are achieved through two groups of stops 16-3a, and the discharge action of the products one by one is more stable and reliable.

[0075] like Figure 4As shown, a loading table 11-1 is provided on the upper portion of the loading frame 11, and an upper support frame 12 is provided on the loading table 11-1. The storage bin 13 includes a right baffle 13-1, a front baffle 13-2, and a left baffle 13-3. The right baffle 13-1 and the left baffle 13-3 are arranged opposite each other, and the front baffle 13-2 and the push plate 14-6 are arranged opposite each other, forming a storage space with variable space. The right baffle 13-1, the front baffle 13-2, and the left baffle 13-3 can all be fixed to the upper support frame 12. Using the above-mentioned storage bin 13 design, the entire push mechanism 14 is used to push the stacked products in the storage bin 13 to one side as a whole, and the side shift conveying mechanism 15 is used to convey the stacked products in a single row to the discharge mechanism. This can ensure the neat arrangement of the products and improve the stability of product loading. The conveying action of the stacked products is flexible and stable. The above-mentioned whole pushing mechanism 14 also includes a driving motor 14-1, a screw 14-2, a screw nut 14-3, a push plate guide rail 14-4 and a push plate slider 14-5.

The push plate guide rail 14-4 is installed on the other side of the upper support frame 12 parallel to the screw 14-2. The other end of the push plate 14-6 slides with the push plate guide rail 14-4 through the push plate slider 14-5. During operation, the drive motor 14-1 rotates the lead screw 14-2, which in turn drives the lead screw nut 14-3 and the push plate 14-6 to move together. The push plate guide rail 14-4 and the push plate slider 14-5 ensure the stability of the movement of the push plate 14-6. Furthermore, the product loading mechanism 100 also includes a single-stack pushing mechanism 17 for pushing a stack of products toward the discharge mechanism 16 in a direction perpendicular to the conveying direction of the side-shift conveyor mechanism 15. The single-stack pushing mechanism 17 includes a pushing driver 17-1, a pushing plate 17-2, a sliding seat 17-3, a pushing guide rail 17-4, and a pushing slider 17-5.

The sliding seat 17-3 is slidably mounted on the frame via the pushing guide rail 17-4 and the pushing slider 17-5. The pushing driver 17-1 can be a telescopic cylinder. When in operation, the pushing driver 17-1 drives the pushing plate 17-2 to move forward, pushing a stack of products at the discharge end of the side-shift conveying mechanism 15 into the stacked product discharge channel formed by the discharge baffle 16-1. This makes the stack of products entering the discharge mechanism 16 relatively independent and free from interference from other products, further improving product loading stability. The above-mentioned side-shift conveying mechanism 15 is preferably a conveyor belt installed on the frame, and a conveyor belt support plate 15-1 is provided below the upper belt of the conveyor belt to support the products on the conveyor belt.

[0076] Reference Figures 8 to 12 As shown, the nut assembly mechanism 300 in this embodiment includes a downward pressure positioning mechanism 32, a nut feeding mechanism 33 and a back pressure nut mechanism 34. The downward pressure positioning mechanism 32 is mounted above the product conveying track 200 and is used to position and press the product on the product conveying track 200. After the product is conveyed to the bottom of the downward pressure positioning mechanism 32, the downward pressure positioning mechanism 32 is actuated to press the product downward to ensure that the product is accurately positioned on the product conveying track 200. The nut feeding mechanism 33 includes a nut discharge plate 33-1, a nut transfer mechanism and a nut transfer mechanism. The nut transfer mechanism has a slide bar 33-10 that can move between the nut receiving station and the nut pressing station and is located at the bottom of the product conveying track 200. The slide bar 33-10 is used to receive the nut and then move it to the nut pressing station. The nut discharge plate 33-1 is connected to the nut loading device. The nut loading device can be an existing spiral vibration loading device, which can convey the nuts to the nut discharge plate 33-1 and arrange them. The outer hexagon of the nut is accurately positioned; the nut transfer mechanism can transfer the nuts on the nut discharge plate 33-1 to the slide bar 33-10 located at the nut receiving station, so that the positioned and neatly arranged nuts are transferred to the slide bar 33-10; the back pressure nut mechanism 34 is arranged below the product conveying track 200, and a nut back pressure hole is provided at the position of the product conveying track 200 facing the nut pressing station, which is used to press the nuts on the slide bar 33-10 located at the nut pressing station into the nut groove on the back of the product. The nuts arranged on the nut discharge plate are placed on the upper side of the nut transfer mechanism by the nut transfer mechanism, and the nuts are moved to the bottom of the back of the product by the nut transfer mechanism. The nuts are directly pressed into the nut groove on the back of the product by the back pressure nut mechanism 34, and cooperate with the downward positioning mechanism 32 on the top of the product to ensure that the back of the nut is accurately pressed and positioned, and the pressing stability is good. It has the advantages of simple and compact structure and efficient and stable nut pressing action, and effectively solves the difficult problems existing in the back nut technology.

[0077] like Figures 8 to 11As shown, in the above-mentioned nut assembly mechanism 300, the downward pressure positioning mechanism 32 includes a base 32-1, a driver mounting seat 32-2, a downward pressure driver 32-3, a pressure block mounting seat 32-5 and a clamping positioning piece.

The downward pressure driver 32-3 drives the clamping positioning piece to move downward to clamp and position the product on the product conveying track 200, which can ensure that the nut is pressed into place accurately and stably. In order to prevent the downward pressure driver 32-3 from generating a reverse impact during the nut press-fitting process, a lateral displacement top block 32-7 capable of lateral sliding is further provided on the upper portion of the driver mounting seat 32-2. The lateral displacement top block 32-7 is connected to the lateral displacement driver 32-6 on one side of the driver mounting seat 32-2. A downward pressure top block 32-4 is further provided on the upper portion of the pressure block mounting seat 32-5. After the downward pressure driver 32-3 drives the pressing positioner to move downward, the lateral displacement driver 32-6 drives the lateral displacement top block 32-7 to move above the downward pressure top block 32-4 to tighten the downward pressure top block 32-4. In this way, after the pressing positioner presses the product, the lateral displacement top block 32-7 is used to tighten the product, so that the force generated by the back pressure nut will not be transmitted to the downward pressure driver 32-3, which is not only beneficial to protecting the downward pressure driver, but also can ensure the stability and reliability of the pressing. The downward pressure driver 32-3 and the lateral displacement driver 32-6 are preferably linear telescopic cylinders.

The above-mentioned nut transfer mechanism can stably remove the nut from the nut discharge plate 33-1 and place it on the slide bar 33-10. The angle of the nut will not change during the transfer process. The transfer action is stable and reliable, effectively reducing the mechanism from getting stuck, and the structural design is compact. The above-mentioned nut upper ejector driver 33-2, slide side shift driver 33-5 and nut lower ejector driver 33-6 are preferably linear telescopic cylinders, which have a fast action response speed and are conducive to ensuring overall assembly efficiency. The nut transfer mechanism of the nut feeding mechanism 33 further includes a slide rod driver 33-8, a slide rod seat 33-9, a limit baffle 33-11 and a guide base 33-12.

A nut removal groove 33-10a is provided on the upper portion of the end of the slide bar 33-10 away from the slide bar seat 33-9. The nut removal groove 33-10a is a regular hexagonal groove that fits the nut. The driving end of the slide bar driver 33-8 is connected to the slide bar seat 33-9 to drive the slide bar 33-10 to move. A limit stopper 33-11 is mounted on the nut assembly platform 31 and located on one side of the slide bar seat 33-9 to limit the movement of the slide bar 33-10. The slide bar driver 33-8 can drive the nut removal groove 33-10a to move between the nut receiving station and the nut pressing station, so that the nut is transferred to the lower back of the product to facilitate pressing the nut from below. The above-mentioned slide rod driver 33-8 also preferably adopts a linear telescopic cylinder, and the limit baffle 33-11 can ensure the positioning accuracy of the slide rod 33-10 at the two workstations.

[0081] Reference Figures 13 to 17As shown, the spring sheet assembly mechanism 400 in this embodiment includes a spring sheet feeding mechanism 42 and a spring sheet grabbing and installing mechanism 45. The spring sheet feeding mechanism 42 and the spring sheet grabbing and installing mechanism 45 are respectively mounted on the spring sheet assembly frame 41. The spring sheet feeding mechanism 42 is located on one side of the product conveying track 200 and is used for automatically loading and arranging spring sheets. The spring sheet grabbing and installing mechanism 45 is installed across the top of the product conveying track 200 in a direction perpendicular to the conveying direction of the product conveying track 200. The spring sheet feeding mechanism 42 has a spring sheet discharge seat 44 located below the spring sheet grabbing and installing mechanism 45. The spring sheet grabbing and installing mechanism 45 is used to grab spring sheets from the spring sheet discharge seat 44 and move them above the product conveying track 200 to assemble the spring sheets on the product on the product conveying track 200. The spring sheet grabbing and installing mechanism 45 has a spring sheet clamping claw 45-9 that is controlled to move horizontally and vertically between the spring sheet discharge station and the spring sheet installation station. The horizontal and lifting movement structures of the spring leaf clamp 45-9 are compactly designed, and the horizontal and lifting movement precisions are high, which enables accurate grasping and high-precision assembly of small-sized spring leaves, improving assembly efficiency and quality.

[0082] like Figure 14 and Figure 16 As shown, in the spring sheet assembly mechanism 400, the spring sheet grabbing and installing mechanism 45 also includes a sliding bracket 45-1, a horizontal sliding seat 45-5, a lifting slide 45-2, a horizontal driver 45-3 and a vertical driver 45-4. The sliding bracket 45-1 spans above the product conveying track 200. The horizontal sliding seat 45-5 is slidably installed on the sliding bracket 45-1 and is connected to the horizontal driver 45-3. The horizontal driver 45-3 drives the horizontal sliding seat 45-5 to move horizontally between the spring sheet discharge station and the spring sheet installation station.

The lifting slide 45-2 is a frame structure located outside the horizontal slide 45-5. The lifting slide 45-2 and the horizontal slide 45-5 slide together vertically. The vertical driver 45-4 is fixedly connected to the horizontal slide 45-5. The lifting slide 45-2 is connected to the driving end of the vertical driver 45-4, and the vertical driver 45-4 drives the lifting slide 45-2 to move vertically. The spring sheet clamp 45-9 is installed at the bottom of the lifting slide 45-2 and is used to grasp and install the spring sheet. The above structural design is conducive to ensuring structural compactness and sliding guide precision, making the horizontal movement and lifting movement structure design of the spring sheet clamp more compact.

[0083] Further, if Figure 14 and Figure 16As shown, in order to ensure the stability of the spring piece grasping and assembly, a horizontal slider 45-7 is provided at the lower part of the horizontal sliding seat 45-5, and a horizontal guide rail 45-6 is provided on the sliding bracket 45-1. The horizontal slider 45-7 is slidably installed on the horizontal guide rail 45-6, so that the horizontal sliding seat 45-5 can stably slide horizontally on the sliding bracket 45-1. The horizontal sliding seat 45-5 is preferably in an inverted "U" shape. The horizontal sliding seat 45-5 is buckled on the sliding bracket 45-1, and the horizontal slider 45-7 is fixed on the inner bottom surface of the horizontal sliding seat 45-5, making the support of the sliding bracket 45-1 for the horizontal sliding seat 45-5 more stable. Vertical sliders 45-8 are respectively provided on the inner sides of the left and right arms of the lifting sliding seat 45-2, and vertical guide rails are provided on the left and right side walls of the horizontal sliding seat 45-5. The vertical sliders 45-8 are slidably installed on the vertical guide rails. The lifting sliding seat 45-2 and the horizontal sliding seat 45-5 are guided on both sides, and the guiding is more stable, which can further ensure the accuracy of the spring piece gripper 45-9 descending to press-fit the spring piece. In order to facilitate the installation of the vertical drive 45-4, a drive mounting seat is fixedly installed on one side of the horizontal sliding seat 45-5 away from the horizontal drive 45-3, and the vertical drive 45-4 is fixed on the drive mounting seat. The drive mounting seat is composed of a vertical plate and a horizontal plate. The bottom of the vertical plate is fixed on the horizontal sliding seat 45-5, the horizontal plate is fixed on the top of the vertical plate, and the vertical drive 45-4 is installed on the horizontal plate. With the above installation structure, the installation positions of the vertical drive 45-4 and the horizontal drive 45-3 are more reasonable and compact, and the structural design is simple and convenient to manufacture. The above-mentioned vertical drive 45-4 and horizontal drive 45-3 are both preferably linear telescopic cylinders, which are convenient to control, have a fast action response speed, and high assembly efficiency.

[0084] As Figure 17As shown, in this embodiment, the spring sheet clamp 45-9 includes a clamp body 45-9-1, with two opposing claws 45-9-2 provided at the lower end of the clamp body 45-9-1. The claws 45-9-2 are rotatably mounted in the mounting cavity of the clamp body 45-9-1. An elastic member (not shown) is provided between the upper ends of the two claws 45-9-2 for elastically clamping the claws 45-9-2. Under the action of the elastic member, the two claws 45-9-2 maintain an elastic tendency to close inward. The elastic member is preferably a spring, with its two ends respectively abutting against the upper extension arms of the claws 45-9-2. When grasping the spring sheet, under the action of downward pressure, the front ends of the two claws 45-9-2 are stretched open by the spring sheet, and then the elastic member clamps the spring sheet from both sides to achieve the grasping of the part. After assembly, the spring sheet clamp 45-9 presses the spring sheet into the mounting portion of the product. Due to the assembly resistance formed between the spring sheet and the product, when the spring sheet clamp 45-9 moves upward, the two claws 45-9-2 overcome the elastic force of the elastic member and open outward, disengaging from the spring sheet and releasing the assembled spring sheet. The above-mentioned spring sheet clamp 45-9 improves the grasping and assembly stability of the spring sheet. In addition, the spring sheet clamp 45-9 has a simple and compact structural design and a small size. It can accurately grasp smaller parts and is easy to arrange and install multiple spring sheet clamps to achieve simultaneous assembly of multiple spring sheets. Furthermore, the lower end of the claw head 45-9-2 is provided with a flange 45-9-2a facing inward. The upper side of the flange 45-9-2a has an outlet arc surface and the lower side has an inlet arc surface, which further facilitates the grasping and release of the spring sheet.

The spiral feeder 42-1 is installed on the spring sheet assembly frame 41. The spiral feeder 42-1 is connected to the spring sheet discharge seat 44 through the spring sheet feeding track 42-2. The spring sheet feeding track 42-2 is installed on the linear vibrator 42-3. The spiral feeder 42-1 and the linear vibrator 42-3 are used to transport the spring sheets at a set angle and arrange them one by one in the spring sheet feeding track 42-2 and transport them to the spring sheet discharge seat 44. Figure 15As shown, a slideway is provided on the spring sheet discharge seat 44, in which a discharge slider 46 is slidably mounted. The discharge slider 46 is provided with a spring sheet positioning groove 46-1. The discharge slider 46 is connected to a discharge cylinder (the discharge cylinder is not shown). The discharge cylinder drives the spring sheet positioning groove 46-1 to move between the loading position 44-1 and the discharging position 44-2. The loading position 44-1 is connected to the discharge port of the spring sheet loading track 42-2 in the spring sheet loading mechanism 42. During the loading process, the discharge cylinder drives the spring sheet positioning groove 46-1 to move to the loading position 44-1. At this time, the spring sheet positioning groove 46-1 corresponds to the position of the spring sheet loading track 42-2. A spring sheet moves onto the spring sheet positioning groove 46-1, and then the discharge cylinder drives the spring sheet positioning groove 46-1 to move forward to the discharging position 44-2. The spring sheet is grabbed from the discharging position 44-2 by the spring sheet clamping claw 45-9. The above-mentioned spring sheet discharge seat structure allows for stable removal of spring sheets from the spring sheet loading track and movement to the material removal position to await capture by the spring sheet gripper, making spring sheet loading and capture more stable and reliable. Furthermore, to ensure accurate alignment of the spring sheet positioning groove 46-1 with the spring sheet loading track 42-2, a stopper 47 for limiting the discharge slider 46 is provided on the spring sheet discharge seat 44, further improving the accuracy of spring sheet discharge. Furthermore, to facilitate installation, an assembly base 43 is also included. The above-mentioned spring sheet discharge seat 44, sliding bracket 45-1, and product conveying track 200 can all be mounted on the assembly base 43. The assembly base 43 is then fixed as a whole to the spring sheet assembly frame 41, facilitating assembly of the various components on the assembly base 43 and facilitating the assembly accuracy of the assembly device.

The screw lifting bracket 52-4 is fixed on the transverse bracket 52-2. The screw lifting sliding plate 52-5 is vertically slidably installed on the screw lifting bracket 52-4. The screw lifting driver 52-6 is installed on the screw lifting bracket 52-4, and the driving end of the screw lifting driver 52-6 is connected to the screw lifting sliding plate 52-5. The screw grabbing plate 52-7 is fixed on the screw lifting sliding plate 52-5. Both the screw transverse actuator 52-3 and the screw lift actuator 52-6 preferably utilize telescopic cylinders. The screw transverse actuator 52-3 drives the transverse bracket 52-2 to move horizontally, which in turn drives the screw grabbing plate 52-7 to move between the screw discharge base 51 and the screw tightening station on the product conveyor track 200. The screw lift actuator 52-6 drives the screw lift sliding plate 52-5 to move up and down, which in turn drives the screw grabbing plate 52-7 to move up and down to absorb or place the screws on the product. During the screw installation process, the screw grabbing plate 52-7 acts as a screw retainer, facilitating the tightening of the screwdriver 53-5. The screw-tightening mechanism 53 also includes a screwdriver support frame 53-1, a screwdriver lift plate 53-2, a screwdriver lift guide rail 53-3, and a screwdriver lift driver 53-4.

After passing through the through hole, the product positioning block is inserted into the center hole of the product to position the product.

[0088] Reference Figures 19 to 22As shown, the product flipping mechanism 600 in this embodiment includes a flip support plate 61, a flip seat 62, and a flip actuator 63. The left and right ends of the flip seat 62 are rotatably mounted on the flip support plate 61 on the corresponding side. The flip actuator 63 is in transmission connection with the flip seat 62, and is used to drive the flip seat 62 to flip, thereby flipping the product. The flip seat 62 has a flip channel 62-1 extending from front to back inside. The flip channel 62-1 has stopper structures on its upper and lower surfaces, respectively, which act as stops. The stopper structures on the upper and lower surfaces of the flip channel 62-1 are staggered in the front-to-back direction and are close to the through-opening. The stop structure below the flip channel 62-1 blocks the product. The through-hole away from the lower stop structure serves as the product entrance. After the product slides in through this entrance, it is blocked by the stop structure on the exit side. The flip actuator 63 then drives the flip seat 62 to flip 180 degrees, so that the back of the product faces upward. At this time, the stop structure originally located at the top and the stop structure located at the bottom swap positions. The lower stop structure no longer blocks the front of the product, allowing the flipped product to slide out of the exit side of the flip channel 62-1. Specifically, in this embodiment, the stop structure includes a limit slide 62-3 provided above or below the flip channel 62-1 and extending forward and backward. The limit slide 62-3 opens at the through-hole on one side and has a limit stop 62-4 at the through-hole on the other side. The limit stops 62-4 on the upper and lower sides are staggered relative to each other in the front-to-back direction. In this way, the product's inherent structural characteristics are utilized to block the product during forward conveyance. Once the product is flipped, it is no longer blocked by the flip seat. The thrust from the previous product can be used to push the flipped product out of the flip seat, making the operation simpler and more stable. As needed, guide grooves 62-2 are provided on the upper and lower surfaces of the flip channel 62-1. The guide grooves 62-2 on the upper and lower surfaces of the flip channel 62-1 face each other. The guide grooves 62-2 accommodate the product's inherent protrusions and also limit the product's angular position, facilitating accurate assembly of subsequent products.

[0089] In the product flipping mechanism 600, to facilitate the processing and fabrication of the internal structure of the flipping channel 62-1, the flip seat 62 is assembled from a first flip half-shell 62a and a second flip half-shell 62b, which can be bolted together. This two-half assembly structure simplifies and facilitates the processing and fabrication of the internal structure of the flipping channel 62-1. Rotating shafts 62c are also mounted on the left and right sides of the flip seat 62. These rotating shafts 62c are supported on the flip support plates 61 on the corresponding sides via bearings, ensuring stable and smooth rotation of the flip seat 62. The aforementioned flip actuator 63 is preferably a motor, the output shaft of which is in transmission connection with the rotating shaft 62c on the corresponding side of the flip seat 62. Using a servo motor to drive the flip seat 62 to rotate makes the product flipping action more stable. Figure 22FIG. 6 shows the operating principle of the product turning mechanism 600. Figure 22 As shown in (a), the product first enters the flip channel 62-1 of the flip seat 62 with its front side facing upwards and is blocked by the stop structure at the outlet end of the flip channel 62-1; then the flip seat 62 rotates 180° clockwise so that the product in the flip channel 62-1 is in the Figure 22 (b) shows the back side facing up, at this time the front side of the product is buckled in the turning channel 62-1, and the stop structure does not block the parts; then, as shown in FIG. Figure 22 As shown in (c), the second product enters the flipping channel 62-1, and the previous flipped product is pushed out of the flipping channel 62-1 and transported to the next assembly station.

The wax injection box 75 is located directly above the wax sealing station via the wax injection lifting actuator 76 and is used to inject wax into the product at the wax sealing position. Specifically, the conveyor mechanism 72 is preferably a belt conveyor mechanism, and limiting ribs 73 are provided on both sides of the conveyor mechanism 72 to prevent the product from deviating from the conveyor mechanism 72. The product positioning mechanism 74 can be provided in pairs on opposite sides of the conveyor mechanism 72. The product positioning mechanism 74 consists of a positioning cylinder and a positioning clamping plate. The positioning clamping plate is fixed to the driving end of the positioning cylinder. When the product moves below the wax injection box 75, the positioning cylinder drives the positioning clamping plate to extend, clamping the product in place. The wax injection lifting driver 76 preferably adopts a telescopic cylinder, whose piston rod is connected to the wax injection box 75. There is an injection nozzle at the bottom of the wax injection box 75. The wax injection lifting driver 76 drives the wax injection box 75 to move downward to the wax injection position of the product, and the injection nozzle of the wax injection box 75 injects wax into the product to seal the exposed nut part.
