Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, and in particular relates to a two-stage transfer mechanism and temporary storage system. Background Technology

[0002] Conveyor lines are common equipment in practical applications for assembly line operations and automated material transport (especially PCB boards).

[0003] In assembly line operations, due to the different processing rhythms between workstations, products (including but not limited to PCB boards) are prone to lingering on the conveyor line or unprocessed products flowing out. Therefore, existing patent CN213264243U, "Silicon Wafer Lifting and Conveying Device," proposes a technical solution to address this issue. By adding a temporary storage box at the output end of the conveyor line, products that cannot be processed immediately are placed in the clips of the temporary storage box, thus alleviating the problem of products lingering on the conveyor line. The buffer structures disclosed in existing technologies, including the above-mentioned technical solution, all use a pusher mechanism to push products into or out of the temporary storage box. During this process, the edges of the products rub against the clips of the temporary storage box, potentially damaging the products and causing wear and chipping.

[0004] To address the aforementioned problems, designing a two-stage transfer mechanism and temporary storage system is an important technical issue that those skilled in the art need to solve. Utility Model Content

[0011] Preferably, the transfer assembly is arranged on a support below the conveying line and comprises a jacking transfer cylinder arranged on the support, a translation transfer cylinder arranged above the support, and a carrying rod; the jacking transfer cylinder drives the translation transfer cylinder and the carrying rod to move along the height direction of the conveying line; the translation transfer cylinder drives the carrying rod to move along the running direction of the conveying line and drives the end of the carrying rod to gradually protrude from the output end of the conveying line.

[0012] Preferably, the output end of the carrying rod is provided with a stopper protruding from the upper surface thereof; the output end of the activated transfer assembly is located outside the output end of the conveying line and carries the product output from the conveying line.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. Furthermore, in the description of the schemes, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0030] As shown in Figures 1 to 5 The present application discloses a two-stage transfer mechanism and a temporary storage system. The two-stage transfer mechanism comprises a conveying line 1 and a switching assembly 2 as shown in Figure 4 The switching assembly 2 is arranged inside the conveying line 1. The switching assembly 2 can be lifted and / or moved relative to the conveying line 1, and the output end of the activated switching assembly 2 is located outside the output end of the conveying line 1 and carries the products output on the conveying line 1, increasing the moving stroke of the products. The switching assembly 2 is integrally arranged with the conveying line 1, improving the integration degree and reducing the floor area.

[0031] As shown in Figure 2 and Figure 4 The conveying line 1 is preferably a belt conveying line, and the switching assembly 2 is located between two parallel arranged belts. As shown in Figure 1 and Figure 4 The conveying line 1 comprises first conveying wheels 11 at the input end and the output end and a group of second conveying wheels 12 arranged at intervals between the first conveying wheels 11. The upper surfaces of the second conveying wheels 12 are coplanar with the upper surfaces of the first conveying wheels 11. The first conveying wheels 11 and the second conveying wheels 12 are driven to rotate by a conveying motor 10. The two groups of first conveying wheels 11 at the input end and the output end of the conveying line 1 drive the belts to rotate, and the second conveying wheels 12 enhance the carrying capacity of the conveying line 1, and at the same time make the movement process of the conveying line 1 more smooth.

[0032] like Figure 4 As shown, guide components 13 are also provided on both sides of the conveyor line 1. The guide components 13 limit and guide the products placed on the conveyor line 1 on both sides. Specifically, the guide component 13 includes a guide cylinder 131, a guide rod 132, and a set of guide rollers 133. The set of guide rollers 133 are spaced apart on the guide rod 132; further, the guide rollers 133 are located between two adjacent first conveyor wheels 11 and second conveyor wheels 12, or between two second conveyor wheels 12. The guide cylinder 131 drives the guide rod 132 and the guide rollers 133 to move along the width direction of the conveyor line 1. The guide components 13 shown are provided on the outside of the conveyor line 1. By adjusting the distance between the two guide components 13, products of different widths can be adapted; that is, the guide components 13 can be adjusted according to the width of the conveyed products to adapt to products of different widths and improve the flexibility of the conveyor line.

[0033] like Figure 2 As shown, the transfer assembly 2 includes at least a support rod 23 that moves along the direction of the conveyor line 1, and the support rod 23 is provided with a vacuum adsorption hole 230 for adsorbing products. After startup, the product is placed on the transfer assembly 2 via the conveyor line 1 and adsorbed by the vacuum adsorption hole 230. At the same time, the transfer assembly 2 moves the product away from the output end of the conveyor line 1 to increase the product's travel distance. The product is also moved up and down by the support rod 23 during placement. The product output from the conveyor line is stably adsorbed by the support rod, which moves the product up and down within the magazine. This differs from the prior art where products are pushed in and out of the magazine, reducing product wear and debris generation, and extending the product's service life.

[0034] Specifically, the switching assembly 2 is arranged on the support 100 below the conveying line, and includes a jacking switching cylinder 21 arranged on the support 100, a translation switching cylinder 22 arranged above the support 100, and the carrying rod 23. The jacking switching cylinder 21 drives the translation switching cylinder 22 and the carrying rod 23 to move along the height direction of the conveying line 1; the translation switching cylinder 22 drives the carrying rod 23 to move along the running direction of the conveying line 1, and drives the end of the carrying rod 23 to gradually protrude from the output end of the conveying line 1. When the length of the product conveyed on the conveying line 1 is relatively long, or the actual conveying distance of the product is much larger than the conveying length of the conveying line 1, the product can be further moved by starting the switching assembly 2; that is, the conveying line and the switching assembly form a two-stage transfer mechanism, and the conveying length of the product can be determined according to the length of the conveyed product and the actual situation of the applicable unit; and the difference between the actual conveying length and the conveying length of the conveying line is compensated by the switching assembly, the switching assembly carries the product output on the conveying line, increases the moving stroke of the product, and can adapt to products of different lengths, and improves the conveying flexibility.

[0035] Further, the output end of the carrying rod 23 is provided with a stop block 231 protruding from the upper surface thereof, and the placement position of the product can be defined by the stop block 231, thereby ensuring the stability of the product on the carrying rod 23. The carrying rod 23 is driven upward by the jacking switching cylinder 21, and vacuum adsorption is started at the same time when the product is contacted, so that the product is stably adsorbed on the carrying rod 23; the jacking switching cylinder 21 continues to move upward to separate the product from the conveying line 1. The carrying rod 23 and the product thereon are further driven by the translation switching cylinder 22 to move toward the output end. The vacuum adsorption hole is arranged on the carrying rod 23 of the switching assembly 2, and the product is stably adsorbed through the vacuum adsorption hole during movement, thereby ensuring the stability of the product during the storage process; at the same time, the product is placed in the temporary storage assembly in a lifting manner by the jacking switching cylinder 21 and the translation switching cylinder 22, and compared with the pushing storage in the prior art, no friction and dust are generated during the entire placement process, thereby further ensuring the yield of the product.

[0036] As shown in Figure 1 and Figure 5 , the temporary storage system includes the two-stage transfer mechanism described above, and includes the conveying line 1, the switching assembly 2, and the temporary storage assembly 3. Specifically as shown in Figure 1As shown, the temporary storage assembly 3 is located at the output end of the conveying line 1 and the switching assembly 2, and the temporary storage assembly 3 can be gradually lifted relative to the conveying line 1 and the switching assembly 2. By arranging the temporary storage assembly 3 at the output end of the conveying line 1, the products on the conveying line 1 are automatically and gradually transferred into the temporary storage assembly 3, so as to alleviate the problem of product stagnation and accumulation on the conveying line 1 or the processing position, avoid product wear and tear, and ensure the good product yield flowing into actual application.

[0037] Specifically as shown, Figure 5 As shown, the temporary storage assembly 3 comprises a linear module 31 arranged in the vertical direction, and a bearing seat 32 arranged on the linear module 31. The linear module 31 is a known existing structure, and thus is not limited herein. The bearing seat 32 is provided with a temporary storage box for storing products; the linear module 31 drives the bearing seat 32 and the temporary storage box to lift. A group of clips are arranged in the temporary storage box, and the height of the clips is greater than the thickness of the products, so that the bearing rod 23 can drive the products to lift in the clips. The structure of the clips and the temporary storage box can refer to the existing patent CN210364796U, “Insulating plate finished product transfer device”, and thus is not described herein.

[0038] Further, a bearing conveying line 321 for placing the temporary storage box is arranged below the bearing seat 32, and the bearing conveying line 321 is driven to rotate by a bearing motor 322. Further, the bearing conveying line 321 is a positive and negative conveying line, that is, the bearing motor 322 is a servo motor, which can drive the bearing conveying line 321 to rotate towards the conveying line 1 or rotate away from the conveying line 1, which can be controlled according to application requirements. The bearing conveying line 321 can be a known belt conveying line or a roller conveying line, and thus is not limited herein. In addition, in other embodiments, the bearing conveying line 321 can also be replaced by other known components with linear movement function, such as a lead screw, a slide rail and other known structures, which are only taken as examples in the form of a conveying line for illustration herein. Further, the bearing conveying line 321 is fixed on a bearing frame, the bearing frame is slidingly connected to the linear module 31 and is lifted by the linear module 31 synchronously with the bearing frame. In the utility model, the bearing frame is preferably designed in the form of a triangular plate to enhance the bearing capacity; in other embodiments, the structure of the bearing frame can also be in other forms, which are not limited herein. The running direction of the bearing conveying line 321 is perpendicular to the running direction of the linear module 31; specifically, the running direction of the bearing conveying line 321 can be parallel to the running direction of the conveying line 1, or can be perpendicular to the running direction of the conveying line 1, which can be adjusted according to actual application requirements, and thus is not limited herein. In the utility model, the conveying line 1 is preferably parallel to the conveying line 1.

[0039] Further, the bearing seat 32 is provided with a sensor 332 for detecting whether the temporary storage box is present on the bearing conveying line 321, and a sensor 333 provided at the output end of the bearing conveying line 321. The sensor 332 and the sensor 333 are preferably opposite-acting sensors, and in other embodiments, known sensors such as infrared sensors can be used instead, which are not limited herein. The bearing seat 32 is provided with a limiting support 33 which spans the bearing conveying line 321, and the limiting support 33 is provided with a limiting cylinder 331.

[0040] The temporary storage box is fed from the end of the conveying line 1 which is far away from the output end, and the sensor 333 detects the presence of the temporary storage box and sends a start signal to the bearing motor 322 and the translation adapter cylinder 22. The temporary storage box is driven by the bearing motor 322 to move forward (towards the output end of the conveying line 1). When the sensor 332 detects that the temporary storage box is present on the bearing conveying line 321, a stop signal is sent to the bearing conveying line 321, and an enable signal is sent to the limiting cylinder 331, and the limiting cylinder 331 applies a force to the side wall of the temporary storage box to stably clamp the temporary storage box. After the limiting cylinder 331 clamps the temporary storage box, a lifting signal is sent to the linear module 31 to drive the temporary storage box to move upward or downward to any empty temporary storage space in the temporary storage box which is parallel to the output end of the conveying line 1.

[0041] The bearing rod 23 and the product are driven by the translation adapter cylinder 22 to move towards the bearing conveying line 321, and at this time the product is higher than the temporary storage space of the temporary storage box. After the translation adapter cylinder 22 drives the product to extend into the temporary storage space, the jacking adapter cylinder 21 is driven to lower until the product is placed in the temporary storage space. From this point, the adapter assembly 2 is reset, and the linear module 31 further drives the temporary storage box to move upward or downward; and the above operation is repeated until all temporary storage spaces in the temporary storage box are filled with products.

[0042] When all temporary storage spaces in the temporary storage box are filled with products or the linear module 31 moves to the limit position, the linear module 31 drives the bearing conveying line 321 and the temporary storage box to move reversely to the initial position. A stop clamping signal is sent to the limiting cylinder 331. After the limiting cylinder 331 is disengaged from the temporary storage box, a start signal is sent to the bearing motor 322, and the temporary storage box is driven by the bearing motor 322 to move reversely (towards the output end of the conveying line 1 which is far away). When the temporary storage box moves to the sensor 333 again, the sensor 333 sends a take-out signal to remind the worker or the take-out robot to take out the temporary storage box from the bearing conveying line.

[0043] The utility model still has a variety of implementation manners, all technical schemes formed by using equivalent transformation or equivalent transformation fall in the protection scope of the utility model.
