Description

Technical Field

[0001] This invention relates to the field of production lines, and more specifically to a continuous conveyor belt production line. Background Technology

[0002] Assembly lines are primarily used for material handling, transferring materials from one location to another, facilitating material transport and improving production automation. In mobile phone dispensing and inspection equipment, the mobile phone dispensing and inspection assembly line plays a crucial role in connecting various work processes within the automated equipment, greatly contributing to production efficiency and the expansion of production processes. In the mobile phone industry, traditional assembly lines sequentially feed products into workstations, following a sequential order, with each process operating at a uniform pace. This method results in excessively long waiting times for subsequent products while the previous process is in operation, hindering the need to increase production capacity and meet the demands of mass production. Therefore, there is a need for a simple, continuous, synchronous conveyor belt assembly line that allows products to flow to the next process without interrupting the operation of the previous process. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a novel continuous conveyor belt production line that solves the problem that in existing production lines, while the preceding process is in operation, subsequent products can only wait.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] A continuous conveyor belt production line for automatically conveying different products to different workstations includes at least one conveyor frame. Two transmission lines are arranged opposite each other on the upper part of the conveyor frame to convey products to different workstations. A lifting and positioning mechanism and a light source lifting mechanism are arranged on the two opposite outer sides of the conveyor frame. The lifting and positioning mechanism includes a lifting drive, a lifting guide, and a positioning plate. The lifting drive is located on the outer side of the conveyor frame, and its working end is connected to the positioning plate through the lifting guide. The positioning plate passes through the conveyor frame and is located between the two transmission lines. The lifting drive drives the positioning plate to move along the lifting guide to lift the product, while simultaneously clearing the space below to allow the next product to be conveyed normally.

[0006] Furthermore, the through-plate frame includes a first upright and a second upright arranged in parallel, a transmission line is arranged on the side of the first upright near the second upright, and another transmission line is arranged on the side of the second upright near the first upright; the light source lifting mechanism is arranged on the side of the first upright away from the second upright, and the lifting and positioning mechanism is arranged on the side of the second upright away from the first upright.

[0007] Furthermore, the transmission line is a three-section synchronous belt assembly line. Each section of the assembly line includes a conveyor motor, a tensioning wheel assembly, a synchronous wheel assembly, and a synchronous belt. The tensioning wheel assembly and the synchronous wheel assembly are located on the same side of the upright of the plate frame and are linked by the synchronous belt. The conveyor motor is located on the outside of the upright of the plate frame, and its working end is connected to a roller of the synchronous wheel assembly.

[0008] Furthermore, the lifting guide includes a lifting mounting plate, a lifting connecting plate, and a lifting guide rail. The lifting mounting plate is disposed on the outside of one of the uprights of the through-plate frame. The lifting connecting plate is slidably disposed on the lifting mounting plate via the lifting guide rail. The working end of the lifting drive is connected to the bottom of the lifting connecting plate, and the top of the lifting connecting plate is connected to the positioning plate, so that the lifting drive drives the positioning plate to move along the lifting guide rail.

[0009] Furthermore, a connecting arm is provided on one side of the positioning plate, and the upright frame of the through plate body is provided on the upper side of the lifting mounting plate, with a through groove. The connecting arm of the positioning plate passes through the through groove and connects to the top of the lifting connecting plate.

[0010] Furthermore, the positioning plate is provided with at least one positioning pin and a suction cup, so that the positioning pin is inserted into the product and the suction cup picks up the product.

[0011] Furthermore, the lifting and positioning mechanism also includes a blocking component, which includes a blocking mounting base, a blocking cylinder, and a blocking block. The blocking mounting base is mounted on a vertical frame of the through-plate frame and located on the side of the positioning plate. The blocking cylinder is mounted on the blocking mounting base, and its working end is connected to the blocking block to drive the blocking block to move upward to separate the products.

[0012] Furthermore, the light source lifting mechanism includes a lifting cylinder, a cylinder mounting base, a lifting mounting plate, a lifting connecting plate, a lifting guide rail, and a light source assembly. The cylinder mounting base and the lifting mounting plate are located on the outside of one of the uprights of the through-plate frame. The lifting connecting plate is slidably mounted on the lifting mounting plate via the lifting guide rail. The lifting cylinder is mounted on the cylinder mounting base, with its working end connected to the bottom of the lifting connecting plate. The top of the lifting connecting plate is connected to the light source assembly, so that the lifting cylinder drives the light source assembly to move along the lifting guide rail.

[0013] Furthermore, the light source assembly includes a light source connecting rod and light source modules disposed at both ends of the light source connecting rod. The light source module includes a light source fixing base, a light source adjusting base, and a light-emitting unit. The light source fixing base is disposed at the end of the light source connecting rod. An adjusting member is disposed at the bottom of the light source adjusting base and is movably connected to the light source fixing base through the adjusting member to adjust the illumination angle of the light-emitting unit disposed at the top of the light source adjusting base.

[0014] Furthermore, a return conveyor line is provided at the lower part of the plate frame. The return conveyor line includes a drive motor, a linkage shaft, and two return conveyor lines. They are arranged opposite each other at the lower part of the plate frame and linked together by the linkage shaft. The drive motor is located on one side of the plate frame, and its working end is connected to the linkage shaft to drive the two return conveyor lines to move.

[0015] Compared to existing technologies, the present invention offers several advantages. It features a simple structure and convenient operation. Products are placed into the feed end of the production line, and two conveyor lines operate synchronously to transport them to the processing station. A lifting drive unit positions and lifts the positioning plate, creating space below. This ensures that while the previous process is in operation, subsequent products can flow to the next process without interruption. Each conveyor frame corresponds to a process and can be configured and converted according to processing requirements. This increases production capacity and expands the possibilities for process expansion, allowing for more flexible process layout. Furthermore, it can accommodate different products, automatically guiding them to different stations for dispensing and inspection. Subsequent products do not need to wait for previous products to complete their processing; instead, they are diverted to other stations, saving time and improving efficiency. This invention has significant market application value. Attached Figure Description

[0024] To facilitate understanding of the present invention by those skilled in the art, specific embodiments of the present invention are described below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0025] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "mounted," "fixed," "front," "rear," and similar expressions used in this specification are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0027] One embodiment of the present invention is as follows: Figure 1 , 2 As shown, this continuous conveyor belt 24 production line is used to automatically transport different products to different workstations. It includes at least one conveyor frame 1, with two transmission lines 2 arranged opposite each other on the upper part of the conveyor frame 1. The products are transported to different workstations through the two transmission lines 2. A lifting and positioning mechanism 3 and a light source lifting mechanism 5 are arranged on the two opposite outer sides of the conveyor frame 1. The lifting and positioning mechanism 3 includes a lifting drive 31, a lifting guide 32, and a positioning plate 33. The lifting drive 31 is located on the outer side of the conveyor frame 1, and its working end is connected to the positioning plate 33 through the lifting guide 32. The positioning plate 33 passes through the conveyor frame 1 and is located between the two transmission lines 2. The lifting drive 31 drives the positioning plate 33 to move along the lifting guide 32 to lift the product, while avoiding gaps below to allow the next product to be transported normally.

[0028] The continuous synchronous conveyor belt 24 assembly line in this embodiment is suitable for screen mounting, mobile phone frame guiding dispensing, and inspection in the 3C industry. First, a handling robot places the product into the feed end of the assembly line, and two conveyor lines 2 run synchronously to move the product to the processing station. Then, the lifting drive 31 drives the positioning plate 33 to position and lift the product, clearing any gaps below. This ensures that while the previous process is in operation, it does not affect the flow of subsequent products to the next process. Simultaneously, data on the inflow and outflow of each product is effectively recorded, identifying specific operational information and distinguishing between good and bad products for subsequent centralized processing of defective items. Furthermore, each process... The product's positioning function needs to be accurate, reliable, and consistent to effectively guarantee product quality. This new type of continuous conveyor line can achieve parallel operation between various workstations on the line. Each conveyor frame 1 of the line corresponds to one process and can be spliced ​​and converted according to processing requirements. On the one hand, it increases production capacity, and on the other hand, it increases the possibility of production process expansion, making the process layout more flexible. Furthermore, it can handle different products, allowing products to automatically flow to different workstations for processing. Subsequent products do not need to wait for the previous products to finish processing, but instead adopt a diversion method to continue to other workstations, saving operation time and improving work efficiency.

[0029] Specifically, the cylinders, motors, and other components selected in this embodiment are all existing components; the two transmission lines 2 are arranged opposite each other on the two inner sides of the upper part of the plate frame 1, with the left end of the two transmission lines 2 being the inlet end and the right end being the outlet end; the light source lifting mechanism 5 is arranged on the front side of the plate frame 1, and the lifting and positioning mechanism 3 is arranged on the rear side of the plate frame 1. A processing mechanism is installed at the lifting and positioning mechanism 3 to form a processing station. When the transmission line 2 carries the product into the position of the lifting and positioning mechanism 3, the lifting drive 31 drives the positioning plate 33 to position and lift the product, so that the lower part is cleared, and at the same time, it does not affect the flow of the subsequent products to the next process.

[0030] In this embodiment, as Figure 2 As shown, the through-plate frame 1 includes a first upright and a second upright 12 arranged in parallel. A transmission line is arranged on the side of the first upright near the second upright 12, and another transmission line is arranged on the side of the second upright 12 near the first upright. The light source lifting mechanism 5 is arranged on the side of the first upright away from the second upright 12, and the lifting and positioning mechanism 3 is arranged on the side of the second upright 12 away from the first upright.

[0031] Specifically, the first upright is the front side 11, and the second upright is the rear side. Guide guards are provided at the top of the first and second uprights along their own length to prevent the two transmission lines 2 from shifting when transporting products. The second upright 12 is provided with a through groove 13 at the position of the lifting and positioning mechanism 3. The positioning plate 33 passes through the through groove 13 of the second upright 12 and is located between the two transmission lines 2. The lifting drive 31 drives the positioning plate 33 to move up and down in the through groove 13 to lift and lower the product.

[0032] In this embodiment, as Figure 3 As shown, the transmission line 2 is a three-section synchronous belt 24 assembly line. Each section of the assembly line includes a conveyor motor 21, a tensioning wheel set 23, a synchronous wheel set 22, and a synchronous belt 24. The tensioning wheel set 23 and the synchronous wheel set 22 are located on the same side of the upright of the plate frame 1 and are linked by the synchronous belt 24. The conveyor motor 21 is located on the outside of the upright of the plate frame 1, and its working end is connected to a roller of the synchronous wheel set 22.

[0033] Specifically, the conveyor frame 1 is also equipped with a width adjustment component, and the transmission line 2 is mounted on the width adjustment component. The distance between the two transmission line bodies 2 is adjusted by the width adjustment component to accommodate products of different sizes. During operation, the product is fed into the transmission line body 2 from the left, and the synchronous belt 24 moves the product to the right. The lifting drive component 31 of the lifting and positioning mechanism 3 drives the positioning plate 33 to the initial position, that is, below the upper surface of the synchronous belt 24, so that the positioning plate 33 is lower than the synchronous belt 24 and does not affect the product conveying. When the transmission line body 2 carries the product into the position of the lifting and positioning mechanism 3, the lifting drive component 31 drives the positioning plate 33 to position and lift the product, so that the space below is cleared, and at the same time, it does not affect the flow of subsequent products to the next process.

[0034] In specific implementation, the conveyor motor 21 can be a stepper motor, model Y07-59D1-17155; the conveyor motor 21 is located at the lower part of the upright of the plate frame 1, the tensioning wheel set 23 is located above the roller connected to the rotating shaft of the conveyor motor 21, and the synchronous wheel set 22 is located at the upper part of the upright of the plate frame 1 and is linked by the synchronous belt 24.

[0035] In this embodiment, as Figure 4 , 5 As shown, the lifting guide 32 includes a lifting mounting plate 321, a lifting connecting plate 322, and a lifting guide rail 323. The lifting mounting plate 321 is disposed on the outside of one of the uprights of the through-plate frame 1. The lifting connecting plate 322 is slidably disposed on the lifting mounting plate 321 via the lifting guide rail 323. The working end of the lifting drive 31 is connected to the bottom of the lifting connecting plate 322, and the top of the lifting connecting plate 322 is connected to the positioning plate 33, so that the lifting drive 31 drives the positioning plate 33 to move along the lifting guide rail 323.

[0036] Specifically, the lifting drive component 31 includes a lifting fixed seat 312 and a lifting cylinder 311. The lifting fixed seat 312 and the lifting mounting plate 321 are disposed on the outer side of the second upright 12 of the plate frame 1. There are two lifting guide rails 323, which are parallel and arranged along the height direction of the lifting mounting plate 321. The lifting connecting plate 322 is disposed on the lifting guide rails 323 so that the lifting drive component 31 drives the positioning plate 33 to move up and down.

[0037] In specific implementation, the lifting cylinder 311 is a telescopic cylinder, model JCMBZ25-100F. During operation, the lifting cylinder 311 first drives the positioning plate 33 to move down, so that the positioning plate 33 is lower than the synchronous belt 24, so as not to affect the product conveying. When the transmission line 2 brings the product into the position of the lifting and positioning mechanism 3, the lifting cylinder 311 drives the positioning plate 33 to position and lift the product.

[0038] In this embodiment, as Figure 5 As shown, a connecting arm 333 is provided on one side of the positioning plate 33, and the upright of the through plate frame 1 is located on the upper side of the lifting mounting plate 321, with a through groove 13 provided. The connecting arm 333 of the positioning plate 33 passes through the through groove 13 and connects to the top of the lifting connecting plate 322.

[0039] Specifically, a connecting arm 333 is provided on the rear side of the positioning plate 33. A groove 13 is opened downward on the upper side of the lifting mounting plate 321 on the second upright 12 of the plate frame 1. The positioning plate 33 is located between the two transmission line bodies 2. The connecting arm 333 passes through the groove 13 of the second upright 12 and is connected to the top of the lifting connecting plate 322. The lifting drive 31 drives the positioning plate 33 to move up and down in the groove 13 to lift and lower the product.

[0040] In this embodiment, as Figure 5 As shown, the positioning plate 33 is provided with at least one positioning pin 331 and a suction cup 332, so that the positioning pin 331 is inserted into the product and the suction cup 332 picks up the product.

[0041] Specifically, two vacuum suction cups are provided in the middle of the positioning plate 33, and positioning pins 331 are provided on the side of the positioning plate 33 at the position corresponding to the product positioning hole. The lifting drive 31 drives the positioning plate 33 to lift the product and insert the positioning pins 331. The space below is clear to facilitate the normal transportation of other products.

[0042] In this embodiment, as Figure 5 As shown, the lifting and positioning mechanism 3 also includes a blocking component 34, which includes a blocking mounting base 342, a blocking cylinder 341, and a blocking block 343. The blocking mounting base 342 is mounted on a vertical frame of the through-plate frame 1 and is located on the side of the positioning plate 33. The blocking cylinder 341 is mounted on the blocking mounting base 342, and its working end is connected to the blocking block 343 to drive the blocking block 343 to move upward to separate the products.

[0043] Specifically, the blocking member 34 is located on the left side of the positioning plate 33. When a product flows into the position of the lifting and positioning mechanism 3, the blocking cylinder 341 drives the blocking block 343 to move upward, temporarily blocking the next product. The lifting cylinder 311 drives the positioning plate 33 to position and lift the product, thus clearing the space below. The blocking cylinder 341 then drives the blocking block 343 to move downward, allowing the next product to be transported normally.

[0044] In this embodiment, as Figure 6 As shown, the light source lifting mechanism 5 includes a lifting cylinder 55, a cylinder fixing seat 54, a lifting mounting plate 51, a lifting connecting plate 53, a lifting guide rail 52, and a light source assembly 56. The cylinder fixing seat 54 and the lifting mounting plate 51 are disposed on the outside of one of the uprights of the through-plate frame 1. The lifting connecting plate 53 is slidably disposed on the lifting mounting plate 51 via the lifting guide rail 52. The lifting cylinder 55 is disposed on the cylinder fixing seat 54, and its working end is connected to the bottom of the lifting connecting plate 53. The top of the lifting connecting plate 53 is connected to the light source assembly 56, so that the lifting cylinder 55 drives the light source assembly 56 to move along the lifting guide rail 52.

[0045] Specifically, there are two lifting guide rails 52, which are parallel and arranged along the height direction of the lifting mounting plate 51. The cylinder fixing seat 54 is located in the middle of the lifting mounting plate 51. The lifting cylinder 55 is a telescopic cylinder, model JCMBZ25-100F. When working, when the workstation needs lighting, the lifting cylinder 55 drives the light source assembly 56 to rise.

[0046] In this embodiment, as Figure 6 As shown, the light source assembly 56 includes a light source connecting rod 561 and light source modules 562 disposed at both ends of the light source connecting rod 561. The light source module 562 includes a light source fixing seat 563, a light source adjusting seat 564, and a light-emitting unit 565. The light source fixing seat 563 is disposed at the end of the light source connecting rod 561. An adjusting member 566 is disposed at the bottom of the light source adjusting seat 564 and is movably connected to the light source fixing seat 563 through the adjusting member 566 to adjust the illumination angle of the light-emitting unit 565 disposed at the top of the light source adjusting seat 564.

[0047] Specifically, the bottom of the light source adjustment base 564 is rotatably connected to the light source fixing base 563 via a connecting pin; the adjustment member 566 is disposed on the outside of the connecting pin, and the adjustment member 566 has an arc-shaped adjustment hole and a locking member disposed along the width direction of the light source adjustment base 564. The locking member passes through the arc-shaped adjustment hole and is connected to the light source fixing base 563. By adjusting the position of the locking member in the arc-shaped adjustment hole, the illumination angle of the light-emitting unit 565 is adjusted.

[0048] In practice, the illumination angle of the light-emitting unit 565 is first adjusted according to the product position. The tilt angle of the light-emitting unit 565 is adjusted by adjusting the position of the positioning pin in the arc-shaped adjustment hole. After the angle is adjusted, the stop nut is screwed in to press the stop ring, so that the stop ring is locked into the side of the arc-shaped adjustment hole for tight positioning. When the product needs to be visually positioned by a camera at the workstation, the lifting cylinder 55 of the light source lifting mechanism 5 drives the light source assembly 56 to rise. After rising, the light source is turned on to illuminate the product features.

[0049] In this embodiment, as Figure 7 As shown, a return conveyor line 4 is provided at the lower part of the plate frame 1. The return conveyor line 4 includes a drive motor 41, a linkage shaft 42, and return conveyor lines 43. There are two return conveyor lines 43, which are arranged opposite to each other at the lower part of the plate frame 1 and are linked by the linkage shaft 42. The drive motor 41 is located on one side of the plate frame 1, and its working end is connected to the linkage shaft 42 to drive the two return conveyor lines 43 to move.

[0050] Specifically, the drive motor 41 is the same as the conveyor motor 21 of the transmission line 2. The return conveyor line 43 consists of a return synchronous pulley and a synchronous belt 24, which is used to return the processed products to the receiving position. The left end of the production line is the feeding and receiving end, and a lifting mechanism is installed at the right end. The lifting mechanism moves the products located on the upper layer of the transmission line 2 down to the return conveyor line 43, and the return conveyor line 43 drives them to move to the left to the receiving position. A blocking component 44 is set on the return conveyor line 43. The structure of the blocking component 44 is the same as that of the blocking member 34, which is used to separate the products.

[0051] In this embodiment, as Figure 1 As shown, a barcode scanning mechanism 6 is installed at the material inlet of the production line to automatically input information for each product's barcode using a barcode scanner. When this production line is used as a mobile phone dispensing and testing equipment, it plays a key role in connecting various work processes within the automated equipment, greatly contributing to production efficiency and the expansion of production processes.

[0052] For example, the entire production line is divided into two layers. The upper layer is the feeding production line, which is divided into 6 sections: feeding buffer section, guiding & dispensing section 1, buffer section, guiding & dispensing section 2, inspection section 1, and inspection section 2. The lower production line is the carrier return track, which is divided into 2 sections. When products are continuously fed, product A first flows to guiding & dispensing section 1, and then is lifted to the working position and placed below it to avoid airflow. Product B can flow smoothly to guiding & dispensing section 2 and is simultaneously lifted to the working position. At this time, products A and B are simultaneously dispensing at the working position. After completion, products A and B can enter inspection station 1 and inspection station 2 in the same way and perform inspection operations simultaneously. The time efficiency is twice that of the traditional production line. After the entire process is completed, the material can be returned to the feeding position by the lower production line.

[0053] Compared to traditional assembly lines, the assembly line in this embodiment allows products to flow to the next process while the previous process is in operation. This increases production capacity and expands the possibilities for production process expansion, making process layout more flexible. At the same time, it effectively records data for the inflow and outflow of each product, identifies specific operational information, and distinguishes between good and bad products to facilitate centralized processing of defective products. In addition, the product positioning function of each process needs to be accurate, reliable, consistent, and effective to ensure product quality.

[0054] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this invention specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
