Description

Technical Field

[0001] The present invention relates to the technical field of automated transmission, and particularly relates to an automated high-efficiency transmission device and method based on stepped parts. Background Art

[0002] In modern industrial production, there are extremely high requirements for the efficient and automated alignment and transmission of various parts, which is directly related to production efficiency and cost control. As a part with a specific shape (stepped), the nail gun cartridge has a wide range of applications in many fields, such as in the construction decoration and furniture manufacturing industries for fastening connection operations.

[0003] Currently, in the production and subsequent processing process of the nail gun cartridge, there are many challenges in its alignment and transmission link. Existing transmission technologies often cannot fully adapt to the unique stepped structure of the nail gun cartridge, resulting in difficulties in quickly and accurately arranging the nail gun cartridges in a predetermined direction and order during the alignment process. This problem makes the alignment operation usually require a large amount of manual intervention and has a very low degree of automation. Workers have to spend a lot of time and energy manually adjusting the arrangement direction of the nail gun cartridges, seriously affecting production efficiency.

[0004] In addition, in the transmission stage, existing transmission devices lack the effective positioning and directional conveying capabilities for stepped nail gun cartridges. During the conveying process, the nail gun cartridges are prone to situations such as direction deviation and position disorder, which requires manual monitoring and correction at all times. The participation of a large number of workers not only greatly increases the labor cost of the alignment and transmission process, but also introduces many quality instability factors due to the differences and fatigue of manual operations. Moreover, due to the low efficiency and low degree of automation of the alignment and transmission, it is difficult to achieve a high degree of automated integration in the entire production process. There is no smooth connection between the front and back processes, resulting in a large amount of waiting time, greatly restricting the improvement of the overall production efficiency.

[0005] In summary, the existing nail gun cartridge alignment and transmission technologies have significant defects of low efficiency and low degree of automation when facing stepped nail gun cartridges, and there is an urgent need for a new technical solution to solve these problems to meet the growing industrial production needs.

The limiting elastic block includes a limiting column, a fixed block, and a limiting spring arranged between the two. The free end of the limiting column is provided with an upward wedge surface. The limiting plate is provided with a through chute along the thickness direction, and the limiting column slides in the chute;

[0011] The flipping and recycling mechanism further includes a recycling and blanking structure, which includes a blanking cylinder and a blanking push frame. The blanking push frame is composed of a bottom plate and two symmetric blanking push plates. A through groove for the blanking push plate to pass through is opened on the positioning plate.

[0012] Furthermore, the rocker plate transfer mechanism includes a fixed frame and a transfer structure slidably connected to the top of the fixed frame. The transfer structure includes a transfer frame and a lateral guide rail cylinder located between the transfer frame and the fixed frame. A vertical transfer cylinder is vertically installed on the transfer frame. A connecting plate is provided at the bottom of the vertical transfer cylinder. Clamping fixture assemblies are symmetrically provided at both ends of the bottom of the connecting plate. The clamping fixture assembly includes a clamping cylinder and clamping plates. Fixed pins that cooperate with the side holes of the rocker plate are provided on the opposite sides of the two clamping plates; Avoidance grooves for avoiding the clamping plates are opened on both the flipping and recycling mechanism and the two limiting plates; A cartridge case separation structure is also connected to the transfer frame, which is used to completely separate the cartridge case from the rocker plate, including a separation cylinder and a separation plate. A number of separation punches corresponding to the cartridge cases are provided at the bottom of the separation plate.

[0013] Furthermore, intermittent drive structures are provided on both the cartridge case conveyor line and the sleeve plate conveyor line. The intermittent drive structure includes a drive cylinder and conveyor push plates located on both sides of the drive cylinder. An intermediate plate is provided on the drive cylinder and is connected and fixed to the conveyor push plates on both sides.

[0014] Furthermore, the plate adding structure includes a transverse movement cylinder and a plate taking cylinder.

A plurality of vacuum suction cups are provided around the installation plate; The flipping structure includes a flipping motor and a flipping frame. The flipping frame is provided with two symmetric fixed clamps. Fixed grooves for accommodating each plate are opened on the fixed clamps; A connecting frame is provided between the two fixed clamps, and the connecting frame is fixed to the output shaft of the flipping motor.

[0015] The beneficial effects of this solution include:

[0016] First, significantly improve the efficiency of whole-column sorting: In this solution, the feeding cylinder pushes the lifting feeding frame to slide regularly on the storage box, and the automatic feeding switch controls the feeding timing to achieve a stable part supply rhythm; And the vibration motor drives the transmission shaft to run eccentrically, and drives the vibration truss through the connecting column, thereby making the rocker plate produce a left-right sliding vibration effect, so that the nail cartridges are affected by the vibration, quickly and accurately fall into the rocker plate and are arranged in an orderly state with the opening facing up. Compared with the traditional method, the whole-column sorting time is greatly shortened, and the number of whole-columns per unit time is significantly increased.

[0017] II. Ensure accurate delivery and reliable commutation: The cartridge case and the platen conveyor lines arranged in parallel ensure the stability of the conveying path. Among them, the additional plate structure uses the transverse movement cylinder and the plate-taking cylinder to work together. With the help of vacuum suction cups, it accurately grabs and places the plates, realizing the transfer of the cartridge case between different plates; the flipping structure drives the flipping frame and the fixed fixture to rotate through the flipping motor, performing precise flipping and commutation operations on the cartridge case. In the intermittent transmission structure, the transmission cylinder pushes the conveying push plate to move intermittently. The thrust stopper, relying on the characteristics of the torsion spring, provides power when pushing the cartridge case and prevents the cartridge case from reversing when stopped, ensuring the high precision and stability of the cartridge case conveying, and effectively avoiding problems such as direction deviation and position disorder during the conveying process.

[0018] III. Efficiently complete the recycling and reuse of the rocker plates: For the recycling and reuse of the rocker plates, first, the rocker plate transfer mechanism uses the horizontal guide rail cylinder and the vertical transfer air cylinder to control the flexible movement and lifting of the transfer rack. The fixture assembly accurately clamps the rocker plate, and the cartridge case separation structure ensures that the cartridge case is completely separated from the rocker plate, laying the foundation for subsequent recycling; then, the flipping recycling mechanism relies on the flipping motor to drive the flipping fixed frame to rotate, using the limit spring block to stably limit the rocker plate, and the recycling and blanking structure realizes the efficient blanking of the rocker plate; the stacking and conveying mechanism and the intermediate connection mechanism sort and convey the rocker plates through the gathering structure and the conveying structure. The supporting bracket flexibly adjusts its height under the action of the lifting air cylinder, smoothly connecting each device. These structures work together to achieve the rapid recycling and reuse of the rocker plates from the production link to the entrance of the whole-column sorting equipment, greatly improving the automation degree of the equipment and the production coherence.

[0019] IV. Significantly reduce labor costs: The vibration sorting unit realizes the automatic whole-column sorting of nail cartridges, the intermittent feeding unit automatically supplies parts, the cartridge case commutation mechanism and the intermittent transmission structure ensure the automatic and accurate conveying and commutation of the cartridge case, and the rocker plate transfer mechanism automatically recycles the rocker plates. Each device operates automatically, greatly reducing manual operations such as manually adjusting the arrangement direction of nail cartridges, monitoring the conveying process, and recycling rocker plates, saving a large amount of labor input and reducing labor costs.

[0020] V. Effectively guarantee the stability of product quality: In this solution, the cartridge case commutation mechanism precisely controls the direction of the cartridge case, and the intermittent transmission structure stably conveys the cartridge case, preventing direction deviation and position disorder during the conveying process. The cartridge case separation structure ensures the complete separation of the cartridge case from the rocker plate, avoiding the influence of residual cartridge cases on subsequent production. These structures effectively reduce the quality instability factors caused by human operation differences and fatigue, ensuring the consistency and stability of product quality.

[0021] VI. Achieving high-level automation integration of the production process: In this solution, the connection and coordination structure among the whole-column sorting equipment, production conveyor equipment, and rocker plate recycling equipment is an intermediate connection mechanism. The intermediate connection mechanism builds a bridge among the equipment and realizes seamless docking among the equipment through the gathering and conveying structure and the adjustable-height support bracket. The automated operation structures of each equipment cooperate closely. From the part whole-column sorting, conveying, processing to the rocker plate recycling cycle, the entire production process is coherent and smooth, greatly reducing the waiting time between the front and back processes, achieving high-level automation integration, and significantly improving the overall production efficiency.

[0022] The present invention also provides a technical solution: An automated and efficient transmission method for stepped parts, which realizes the automated and efficient transmission of stepped parts through the above-mentioned equipment in the claims, including the following steps:

[0023] Step 1: Pour a number of cartridge cases into the whole-column sorting equipment for intermittent feeding and automatic sorting, so that the cartridge cases are arranged in an orderly manner with the openings facing upward in the rocker plate, and then convey the rocker plate to the production conveyor equipment.

[0024] Step 2: During the conveying process, cover the rocker plate with a cover plate through the plate-adding structure, and then flip the cover plate and the rocker plate as a whole through the flipping structure so that the cover plate is located below.

[0025] Step 3: The rocker plate transfer mechanism takes away the rocker plate located above and transfers it to the turning plate recycling mechanism for a 180° flip. After the rocker plate is flipped, it is neatly stacked at the entrance of the whole-column sorting equipment for standby.

[0026] Step 4: Cover the cover plate with a bottom plate again through the plate-adding structure, and then flip the whole through the flipping structure so that the bottom plate is located below and the cartridge case opening is upward.

[0027] The beneficial effects of this solution are as follows: This automated and efficient transmission method takes the rocker plate as the core medium and realizes the high efficiency and precision of the whole-column transmission of cartridge cases. Initially, the whole-column sorting equipment quickly arranges the disordered cartridge cases in an orderly manner on the rocker plate, abandoning the inefficiency of traditional manual whole-column sorting. During the conveying process, a series of precise operations such as "covering the cover plate - flipping, etc." realize the efficient transfer of the cartridge cases from the rocker plate to the sleeve plate, and the whole process is highly automated. Finally, the cartridge cases remain with the openings facing upward, which is convenient for subsequent gunpowder loading, and the rocker plate can be efficiently recycled, comprehensively improving the production efficiency and optimizing the processing preparation.

[0028] Through the above series of steps, the entire transmission method makes full use of the various structures and functions of the automated and efficient transmission equipment for stepped parts. From the aspects of the whole-column sorting, transmission, direction adjustment of cartridge cases to the recycling of rocker plates, a high degree of automation has been achieved. It reduces the links and workload of manual operations, reduces the influence of human factors on the production process, improves the automation degree and production efficiency of the production process, and makes the entire production process run more smoothly and efficiently.

[0029] Further, in step 4, before the bottom plate is covered, it needs to be turned over by 180°. This operation enables the bottom plate to be assembled with the cover plate and the cartridge case in a suitable direction, further optimizing the cooperation of various components during the entire transmission process. By precisely controlling the turning and covering operations of the bottom plate, it is ensured that the opening of the cartridge case faces upward in the final state, meeting the requirements of production and processing, and improving the accuracy and reliability of production.

[0030] Further, in step 2, before the swing plate is removed, the cartridge case is further separated from the swing plate through the cartridge case separation structure. This can ensure that the cartridge case is completely separated from the swing plate before the swing plate is removed, avoiding the influence of the remaining cartridge case on the recycling and reuse of the swing plate, and ensuring the quality of the swing plate recycling and the smooth progress of subsequent alignment and sorting.

A supporting plate 45 is provided at the top of the supporting bracket 42, and a lifting cylinder 43 is provided at the bottom. A connecting slideway 44 is provided between the supporting bracket 42 and the cartridge case conveying line 21; a gathering structure 46 and a conveying structure 47 are respectively provided on the supporting plate 45 in the transverse and longitudinal directions.

[0069] This embodiment also provides an automated and efficient transmission method for stepped parts. The automated and efficient transmission of stepped parts is realized by the above-mentioned equipment in the claims, including the following steps:

[0070] Step 1: Pour a number of cartridge cases into the whole-column sorting device 1 for intermittent feeding and automatic sorting, so that the cartridge cases are arranged in an orderly manner with their openings facing upward in the rocking plate, and then convey the rocking plate to the production conveying device 2.

[0071] Step 2: During the conveying process, cover the rocking plate with a cover plate through the plate adding structure 24, and then turn the cover plate and the rocking plate as a whole through the flipping structure 23 so that the cover plate is located below.

[0072] Step 3: The rocking plate transfer mechanism 31 takes away the rocking plate located above and transfers it to the turning plate recycling mechanism 32 for 180° turning. After the rocking plate is turned, it is neatly stacked at the entrance of the whole-column sorting device 1 for standby. Before taking away the rocking plate, first separate the cartridge cases from the rocking plate further through the cartridge case separation structure 35.

[0073] Step 4: Turn the bottom plate 180 degrees through the flipping structure 23, then cover it on the cover plate through the plate adding structure 24, and then turn the whole through the flipping structure 23 so that the bottom plate is located below and the cartridge case opening faces upward.

[0074] Specific implementation process:

[0075] The stacking and conveying mechanism 34 batch-pushes the rocker plates stacked on its supporting plate 45 onto the vibrating truss 11-1-1 of the sorting device 1. Then, the vibrating motor 11-1-4 starts and drives the vibrating truss 11-1-1 and the rocker plates to slide left and right through the transmission shaft 11-1-5 and the connecting column 11-1-6 to achieve vibration. At the same time, the feeding cylinder 11-2-3 drives the lifting feeding frame 11-2-2 to move downward so that the automatic feeding switch 11-2-4 is lower than the bottom opening of the storage bin 11-2-1, enabling the cartridges to be loaded into the lifting feeding frame 11-2-2. Then, the feeding cylinder 11-2-3 drives the lifting feeding frame 11-2-2 to move upward until the top of the automatic feeding switch 11-2-4 abuts against the limit block 11-3. Continuing to move upward, the automatic feeding switch 11-2-4 rotates due to the obstruction, and the cartridges fall onto the rocker plate and are gradually arranged into the holes of the rocker plate under the action of vibration and inclined gravity to achieve sequential sorting.

[0076] The rocker plate that has completed the sorting of the cartridges is pushed out of the sorting device 1 by the cooperation of the lifting and moving plate cylinder and the lateral moving plate cylinder. At this time, the supporting bracket 42 of the intermediate connecting mechanism 4 rotates under the action of the lifting cylinder 43 to the same inclination angle as the rocker plate, and the rocker plate is transferred to the supporting plate 45. Then, the entire supporting bracket 42 resets to the horizontal state; then, the gathering cylinder 46-2 and the conveying cylinder 47-2 cooperate to convey each single rocker plate to the feeding station 001 of the conveying belt line one by one.

[0077] Synchronously with this process, the feeding cylinder 11-2-3 of the intermittent plate feeding mechanism on the sleeve plate conveying line 22 starts, retracts the lower stop block 25-4, and extends the upper stop block 25-4 to fix the cover plate. The bottom plate falls onto the feeding push plate, and the plate feeding cylinder conveys the bottom plate to the first plate taking station 007. Then, the feeding cylinder 11-2-3 starts again and drives the stop block 25-4 to move in the reverse direction, causing the cover plate to fall onto the feeding push plate.

[0078] Then, the plate feeding cylinders on the cartridge conveying line 21 and the sleeve plate conveying line 22 start simultaneously and push the rocker plate, the cover plate, and the bottom plate to move intermittently through the thrust stopper 12-4. The bottom plate continues to be conveyed forward, so that the rocker plate is located at the first plate adding station 002 and the cover plate is located at the first plate taking station 007; at this time, the plate taking cylinder 24-4 located above the cover plate drives the mounting plate 24-5 to move downward so that the vacuum suction cup 24-6 adsorbs the cover plate. Then, the crosswise moving cylinder 24-3 starts and drives the cover plate to move crosswise above the rocker plate through the transfer frame 24-2 and covers the rocker plate.

[0079] The rocker plate and the cover plate continue to move forward as a whole into the fixed slot 23-4 of the flipping structure 23. The flipping motor 32-1 starts to drive the whole flipping frame 23-2 to flip 180°, so that the rocker plate is on the top. Then it continues to be conveyed to the rocker plate transfer station 004. First, the transverse guide rail cylinder 31-3 of the rocker plate transfer mechanism drives the cartridge case separation structure 35 above the rocker plate. The separation cylinder 35-1 drives the separation punch 35-2 to insert downward into the rocker plate, further pressing the cartridge case downward to completely separate the cartridge case from the rocker plate. Then it drives the vertical transfer air cylinder 31-4 above the rocker plate, adsorbs the rocker plate through the vacuum suction cup 24-6, and then transfers it above the limit slot. Then the vertical transfer air cylinder 31-4 lowers the rocker plate into the limit slot, and the clamping plate 31-5-2 disengages from the rocker plate; during the process of lowering the rocker plate, the limit post 32-5-1 retracts under force. After the rocker plate is completely lowered, under the action of the limit spring 32-5-3, the limit post 32-5-1 resets to fix the rocker plate in the limit slot. Then the flipping motor 32-1 starts to drive the whole flipping and fixing frame to rotate 180°.

[0080] While the flipping process is in progress, the lifting air cylinder 43 in the stacking and conveying mechanism 34 causes the supporting bracket 42 to rotate and tilt to receive the flipped rocker plate; the blanking air cylinder 33-1 drives the blanking push plate to move towards the rocker plate, pushing the flipped rocker plate out of the limit slot and onto the supporting plate 45 of the stacking and conveying mechanism 34. Then the lifting air cylinder 48 jacks up the gathering structure 46 to protrude above the supporting plate 45, and the gathering air cylinder 46-2 drives the gathering plate 46-1 to neatly arrange the rocker plates; when the supporting plate 45 is full of rocker plates, the supporting bracket 42 is raised to have the same inclination angle as the vibrating truss 11-1-1. The limit side plate 11-1-2 on the side of the vibrating truss 11-1-1 moves downward to be lower than the vibrating truss 11-1-1. Then the conveying air cylinder 47-2 drives the conveying plate to push multiple rocker plates onto the vibrating truss 11-1-1 at one time for the next batch of cartridge case alignment and sorting, so as to realize the recycling of the rocker plates.

[0081] At the same time, the cover plate and the cartridge case of the removed rocker plate continue to be conveyed to the second plate adding station 005. The previous bottom plate has been flipped 180° through the flipping structure 23 on the sleeve plate conveying line 22 and is located at the second plate taking station 009. Similarly, the bottom plate is covered on the cover plate, and then is flipped by the flipping structure 23 so that the cover plate is at the bottom and the cartridge case opening is upward; thus, the cartridge cases are sequentially aligned into the sleeve plate and conveyed, waiting to be transferred to the next process.

[0082] In the entire embodiment, a rocker plate is used as the alignment and transfer medium. First, a batch of disordered cartridges are orderly arranged in the rocker plate through an alignment and sorting device, and then the rocker plate filled with cartridges is transported to the production transfer device. During the transfer process, the cartridges in the rocker plate are transferred to the sleeve plate through the process of "covering with a cover plate - flipping - removing the rocker plate - adding a bottom plate - flipping", achieving automated and efficient alignment and transfer, improving production efficiency; and finally, the cartridges still remain in the state of having their openings facing upward, which is convenient for subsequent gunpowder loading; and a high degree of automation is achieved through an automated and efficient transmission device, reducing the links and workload of manual operations, improving the automation degree and production efficiency of the production process, and making the entire production process run more smoothly and efficiently.

It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
