Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment production, in particular to a layered loading and unloading device. Background Art

[0002] In the field of electronic manufacturing and testing, most of the products to be processed (tested) are located on the conveyor line, and then the products to be processed (tested) are moved to the processing (testing) station with the help of a transfer structure. After the processing (testing) is completed, the processed (tested) products are reset to the conveyor line with the help of the aforementioned transfer structure. However, this method has the following problems: 1. The same conveyor line is responsible for loading and unloading. Before the previous product is processed (tested), it is necessary to reserve unloading space for the product on the conveyor line. The latter product will stagnate on the conveyor position for a long time. After the previous product is processed (tested), the latter product will be transferred to the transfer position. In the long run, it is bound to waste a lot of working time, resulting in relatively low production efficiency. 2. The same conveyor line is responsible for loading and unloading, which is easy to cause confusion between unprocessed (tested) products and processed (tested) products, which is not conducive to ensuring production quality. 3. Most transfer structures use telescopic mechanisms to achieve the effect of movement. At present, most telescopic mechanisms use hydraulic cylinders, air cylinders, screw drives, chain drives and other structures. When the required displacement is large, multiple telescopic mechanisms need to be set up to drive. However, if multiple telescopic mechanisms are simply mechanically combined together, a large amount of space will be occupied, which is not conducive to the control of size and has great instability in operation. In addition, once the drive device of the telescopic mechanism is determined, it can only be extended in one direction, which has certain limitations. Utility Model Content

Obviously, the embodiments described below are only a part of the embodiments of the present invention, not all of them. Based on the embodiments recorded in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0057] like Figures 1 to 19 As shown, the layered loading and unloading device includes a support platform 50, on which a transfer assembly, a loading conveying assembly, and a unloading conveying assembly located below the loading conveying assembly are mounted;

[0058] The feeding conveying assembly includes a feeding conveying frame 34, and the feeding conveying frame 34 includes a feeding transfer section 36. The feeding conveying frame 34 is provided with feeding telescopic openings 37 on both sides of the feeding transfer section 36;

[0059] The material unloading conveying assembly includes a material unloading conveying frame 38, and the material unloading conveying frame 38 includes a material unloading transfer section 39. The material unloading conveying frame 38 is provided with a material unloading telescopic opening 41 on both sides of the material unloading transfer section 39;

[0060] The transfer assembly includes a transfer up and down drive device 42, the output end of which is connected to a transfer support seat, and the transfer support seat is provided with two sets of symmetrically arranged and retractable telescopic structure groups;

[0061] The transfer up and down driving device 42 can make the transfer support seat move upward to communicate with the loading conveyor frame 34, and the telescopic ends of the two telescopic structure groups can be respectively placed in the two loading telescopic clearance openings 37. The transfer up and down driving device 42 can make the transfer support seat move downward to communicate with the unloading conveyor frame 38, and the telescopic ends of the two telescopic structure groups can be respectively placed in the two unloading telescopic clearance openings 41;

[0062] The telescopic end of each telescopic structure group is provided with a placement plate 26, and a fixed limit plate 27 is extended upward from the rear end of the placement plate 26. The telescopic end of the telescopic structure group is also provided with a positioning drive device 28, and the output end of the positioning drive device 28 is connected to a movable limit plate 29 which can slide relative to the placement plate 26 and corresponds to the fixed limit plate 27.

[0063] In this embodiment, the transfer up and down driving device 42 can be a linear slide module, a cylinder, etc. The positioning driving device 28 can be a cylinder.

[0064] When in use, the product to be processed (tested) is placed on the loading conveyor rack 34 for conveying. First, the upper and lower driving devices 42 are used to transfer the upper and lower transfer support seat to connect with the loading conveyor rack 34, and the telescopic ends of the two telescopic structure groups are controlled to be in an extended state and placed in the two loading telescopic clearance openings 37 respectively. At this time, the placement plate 26 is located at the two loading telescopic clearance openings 37 and is in a connected state with the loading transfer section 36, and then the positioning driving device 28 is used to drive the movable limit plate 29 to move in a direction away from the fixed limit plate 27. When the product to be processed (tested) on the loading conveyor rack 34 enters the loading transfer section 36, the two placement plates 26 are just located directly below the product to be processed (tested), and then the positioning driving device 28 is used to shrink the position of the movable limit plate 29 so that the product to be processed (tested) can be positioned between the movable limit plate 29 and the fixed limit plate 27, and then the telescopic ends of the two telescopic structure groups are gradually reset, so that the product to be processed (tested) is separated from the loading transfer section 36 and is located on the processing (testing) station. At this time, the loading conveyor rack 34 can deliver the next product to be processed (tested) into the loading transfer section 36 for buffering.

[0065] After the product is processed (tested), the upper and lower driving devices 42 are first used to move the transfer support seat 1 downward to connect with the unloading conveyor rack 38, and then the telescopic ends of the two telescopic structure groups are controlled to be in an extended state and placed in the two unloading telescopic clearance openings 41 respectively. At this time, the processed (tested) product is moved to the unloading transfer section 39, and then the positioning driving device 28 is used to increase the distance between the movable limit plate 29 and the fixed limit plate 27. At this time, the processed (tested) product can be separated from the unloading transfer section 39 and enter the downward movement process position under the transmission of the unloading conveyor rack 38.

[0066] Among them, the placement plates 26 in the two telescopic structure groups can jointly support the product. When the product is moved through the telescopic structure group, the movable limit plate 29 should be driven by the positioning drive device 28 to keep the product in a position pressed against the fixed limit plate 27, so as to avoid shaking of the product.

[0067] In this embodiment, the loading conveyor assembly and the unloading conveyor assembly are set to design the loading conveyor line and the unloading conveyor line in layers. When the previous product to be processed (tested) is located at the processing (testing) station, the next product to be processed (tested) can be cached on the loading transfer section 36, which can effectively reduce working time and thus improve production efficiency. In addition, through the insertion and matching of the telescopic structure group with the loading telescopic clearance opening 37 and the insertion and matching of the telescopic structure group with the unloading telescopic clearance opening 41, the transfer of products between the loading station, the processing (testing) station, and the unloading station can be easily realized.

[0082] It is worth noting here that when a limiting roller 48 is provided on the loading transfer section 36, after the product to be processed (tested) enters the placement plate 26, it is necessary to first appropriately move the transfer support seat 1 upward by transferring the upper and lower driving device 42, that is, to enable the two groups of telescopic structure groups to appropriately lift the product to be processed (tested) until it is higher than the height of the limiting roller 48, and then reset the telescopic ends of the two telescopic structure groups; similarly, when a limiting roller 48 is provided on the unloading transfer section 39, the transfer support seat 1 is moved downward by transferring the upper and lower driving device 42, and it should be appropriately higher than the height of the limiting roller 48 on the unloading transfer section 39, and then the telescopic ends of the two telescopic structure groups are extended, and when the processed (tested) product is located directly above the unloading transfer section 39, the transfer support seat 1 is moved downward by transferring the upper and lower driving device 42, so that the placement plate 26 is connected to the unloading transfer section 39 to facilitate the unloading of the processed (tested) product.

The two primary reversing gears 5 in the primary transmission wheel set are located above the primary transmission gear 4, and the primary transmission gear 4 is located in the area between the two primary reversing gears 5, and the fixed seat 9 is located above the primary transmission gear 4.

[0091] The secondary telescopic seat 3 can be regarded as the telescopic end of the telescopic structure group. Accordingly, the placement plate 26 and the positioning drive device 28 are both installed on the top surface of the secondary telescopic seat 3.

[0092] Preferably, the placement plate 26 is arranged above the positioning drive device 28 through a support block 51;

[0093] The movable limiting plate 29 is provided with a sliding opening 30 through which the placing plate 26 can pass;

[0094] A positioning guide rail 31 is provided at the top of the secondary telescopic seat 3;

[0095] The movable limiting plate 29 is provided with a positioning guide block 32 which can cooperate with the positioning guide rail 31 .

[0096] In this embodiment, the provision of the sliding opening 30 can prevent the movable limiting plate 29 from being separated from the placement plate 26 when moving. Through the cooperation of the positioning guide rail 31 and the positioning guide block 32, the stability of the movement of the movable limiting plate 29 can be improved.

[0097] Preferably, the telescopic drive assembly comprises a telescopic drive device 10 and a synchronous transmission rod 11;

[0098] The output end of the telescopic driving device 10 is sleeved with a driving gear 12;

[0099] The primary transmission gears 4 of the two telescopic structure groups are respectively sleeved on the two ends of the synchronous transmission rod 11, and the synchronous transmission rod 11 is also sleeved with a driving driven gear 13;

[0103] In this embodiment, the placement plate 26 moves forward when it moves closer to the upper material conveying assembly or the lower material conveying assembly, and moves backward when it moves closer to the upper material conveying assembly. Taking the bidirectional telescopic method as an example, when the primary transmission wheel set is located in the middle area of ​​the primary transmission belt 6, the secondary connecting member 18 should be connected to the middle area of ​​the secondary belt top section 57, and the fixing seat 9 should be connected to the middle area of ​​the secondary belt bottom section 58. In this way, the primary telescopic seat 2 and the secondary telescopic seat 3 can telescopically move in both the forward and backward directions relative to the support seat 1.

[0104] When in use, the telescopic drive device 10 is started, and the synchronous transmission rod 11 can be driven to rotate by driving the active gear 12, the driven gear 13 and the telescopic drive belt 14, so that the first-stage transmission gear 4 in the two sets of first-stage transmission wheel groups can be driven to rotate synchronously. Under the transmission action of the first-stage transmission gear 4 and the two first-stage reversing gears 5, the first-stage transmission belt 6 will drive the first-stage telescopic seat 2 to move forward relative to the transfer support seat 1 through the first-stage connecting member 22, thereby completing the first-stage extension action; during the forward movement of the first-stage telescopic seat 2, the second-stage transmission belt 8 arranged thereon also has a tendency to move forward. Since the fixed seat 9 has fixedly restricted the bottom end section 58 of the second-stage belt, in order to meet the displacement requirement, under the support of the two second-stage transmission gears 7, the top end section 57 of the second-stage belt will further move forward with the second-stage connecting member 18, thereby driving the second-stage telescopic seat 3 to move forward relative to the first-stage telescopic seat 2, thereby completing the second-stage extension action, such as Fig.12 and 13 shown.

[0105] It can be seen that in this embodiment, through the linkage design between the first-level telescopic seat and the second-level telescopic seat, a long-range telescopic displacement can be achieved in a limited space to meet the distance requirements between the transfer support seat 1 and the loading transfer section 36 and the transfer support seat 1 and the unloading transfer section 39.

[0106] If the processing (testing) station is located behind the support seat 1, the primary transmission belt 6 can be moved backwards through the telescopic drive assembly, thereby driving the primary telescopic seat 2 and the secondary telescopic seat 3 to move backwards to achieve a reverse elongation effect. Fig.14 and Fig.15 shown.

[0107] In order to maintain the synchronization of the telescopic movement of the two first-stage telescopic seats 2, a synchronous connecting rod 23 is connected between the first-stage telescopic seats 2 of the two telescopic structure groups. In this way, the stability of the two telescopic structure groups when transferring products can be improved.

[0108] The top surface of the transfer support seat 1 is connected to a support frame 25 located between the two telescopic structure groups through a plurality of columns 24. The support frame 25 can be used for wiring and other settings.

[0109] Preferably, a primary guide block 15 is installed on the transfer support seat 1, and a primary slide groove 16 is provided on the primary guide block 15;

[0110] The primary telescopic seat 2 is connected with a primary guide rail 17 that can slide with the primary slide groove 16;

[0111] A secondary guide block 20 is installed on the primary telescopic seat 2, and a secondary slide groove 21 is provided on the secondary guide block 20;

[0112] The secondary telescopic seat 3 is connected with a secondary guide rail 19 which can slide with the secondary slide groove 21 .

[0113] In this embodiment, the cooperation between the primary guide rail 17 and the primary guide block 15 can improve the stability of the primary telescopic seat 2 during telescopic movement; the cooperation between the secondary guide rail 19 and the secondary guide block 20 can improve the stability of the secondary telescopic seat 3 during telescopic movement.
