Description

Technical Field

[0001] This utility model relates to the field of valve assembly technology, specifically to a circulating pallet positioning and locking conveying mechanism for valve assembly lines. Background Technology

[0002] The conveying mechanism is a core component of modern automated valve assembly lines. Its core objective is to achieve precise and reliable pallet positioning on the assembly line, thereby ensuring that assembly robots or operators can complete assembly tasks efficiently and with high quality.

[0003] However, the existing circulating valve assembly line conveyor mechanism cannot perform linkage positioning and locking of the pallet. As a result, after coarse positioning, the pallet cannot be quickly locked during the conveying process. This causes the pallet to deviate by ±5mm during positioning during the conveying process, making it impossible for the assembly robot to perform precise assembly and thus affecting the assembly accuracy of the conveyor mechanism on the valve assembly line. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a circulating pallet positioning and locking conveying mechanism for valve assembly lines, which solves the technical problem that existing circulating valve assembly line conveying mechanisms cannot perform linkage positioning and locking of pallets, resulting in a ±5mm offset of the pallet during positioning during the conveying process, which prevents the assembly robot from performing accurate assembly and thus affects the assembly accuracy of the conveying mechanism on the valve assembly line.

[0005] According to the technical solution provided in the embodiments of this application, a circulating pallet positioning and locking conveying mechanism for a valve assembly line includes a conveying mechanism. The conveying mechanism includes a conveying component, at least one tray, at least one positioning component, and at least one locking component; Each of the pallets is fixed at both ends to the chain of the conveying assembly with screws, so that the conveying assembly drives each of the pallets to rotate along the conveyor frame; Each of the positioning components is vertically mounted on the bottom of each of the pallets, so that the bottom of each of the positioning components engages with the corresponding positioning groove on the conveyor frame. Each of the locking components is vertically mounted on both sides of the positioning groove and electrically connected to the locking button installed in the positioning groove, so that the positioning component is linked to the locking component, thereby locking and fixing the bottom of the tray.

[0006] Furthermore, the positioning component includes a positioning rod and a first elastic element. The positioning rod is movably installed in a movable groove at the bottom of the tray, and the top of the positioning rod abuts against the first elastic element.

[0007] Furthermore, the locking button is movably mounted at the bottom of the positioning groove and abuts against the second elastic member.

[0008] Furthermore, the locking assembly includes a telescopic drive and a locking block. The telescopic drive is vertically mounted on the surface of the conveyor frame, and the bottom of the locking block is fixedly connected to the output end of the telescopic drive, so that the telescopic drive drives the locking block to move upward.

[0009] Furthermore, the locking groove is located at the bottom of the tray, and a locking part is provided on the locking groove. The locking part and the locking block have a toothed structure so that the locking block and the locking part can be engaged and connected.

[0010] Furthermore, the bottom of the tray is also equipped with four pulleys, and each pulley is engaged in pairs on the corresponding guide rails.

[0011] Furthermore, the conveyor is also equipped with several sensors, each located at the front end of the positioning groove, for positioning sensing of the pallet.

[0012] In summary, the beneficial effects of this application are as follows: 1. By setting positioning components at the bottom of each pallet on the conveying mechanism, the positioning rod on the positioning component is pushed into the positioning groove by the return of the first elastic metal spring after compression, thereby accurately positioning the pallet during the conveying process; Second, by setting a locking button at the bottom of the positioning groove, the locking button will activate the two electrically connected locking components after the positioning rod is engaged in the positioning groove. This will cause the telescopic drive on each locking component to drive the locking block to move upward and engage with the locking part set at the bottom of the tray, thereby locking and fixing the tray and preventing the tray from sliding during valve assembly, thus improving the conveying accuracy of the conveying mechanism for valves. Third, the locking button is triggered directly when the positioning rod is inserted into the positioning slot, realizing seamless linkage between mechanical positioning and electronic locking, avoiding the time delay of positioning and locking in the traditional system, thereby reducing the offset from ±5mm to ±1mm.

Detailed Implementation

[0015] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] A circulating pallet positioning and locking conveying mechanism for a valve assembly line, such as Figure 1 As shown, it includes a conveying mechanism 100; and the conveying mechanism 100 includes a conveying component 200, at least one tray 300, at least one positioning component 400 and at least one locking component 500.

[0018] like Figure 2 and Figure 3 As shown, the conveying assembly 200 includes a motor, two transmission gears and two chains. The motor is fixedly connected to the transmission gear located on the left side, and the two transmission gears transmit power to the chain, which is in a ring structure, thereby driving each pallet 300, which is installed between the two chains by screws, to be conveyed. This causes each pallet 300 to rotate along the conveyor frame 600 and move to the assembly station.

[0019] like Figure 2 As shown, several sensors 640 are also installed on the conveyor frame 600. Each sensor 640 is located at the front end of the positioning groove 610 so that each sensor 640 can sense the movement of the pallet 300 to the assembly station, so that the motor on the conveyor assembly 200 can decelerate or brake, thereby improving the conveying accuracy of the assembly line.

[0020] like Figure 2 and Figure 3 As shown, each positioning component 400 is vertically mounted on the bottom of each tray 300, and each positioning component 400 includes a positioning rod 410 and a first elastic member 420. The positioning rod 410 is movably mounted in a moving groove provided on the bottom of the tray 300, and the top of the positioning rod 410 abuts against the first elastic member 420. The first elastic member 420 is a metal spring. When the conveying component 200 moves each tray 300 to the assembly station, the compressed metal spring of the first elastic member 420 returns to its original position, thereby pushing the positioning rod 410 to engage in each positioning groove 610, so that the tray 300 completes the positioning at the assembly station.

[0021] like Figure 2 and Figure 5 As shown, each locking component 500 is vertically installed in pairs on both sides of the positioning groove 610 and electrically connected to the locking button 620 installed in the positioning groove 610, so that the positioning component 400 is linked to the locking component 500. When the positioning rod 410 is engaged in the positioning groove 610, the locking button 620 installed at the bottom of the positioning groove 610 is pressed, so that the locking button 620 compresses the metal spring of the second elastic member 630, thereby causing the telescopic drive component 510 of the locking component 500 electrically connected to the locking button 620 to respond quickly within 0.1-0.3 seconds, thereby activating the telescopic drive component 510, so that the telescopic drive component 510 drives the fixedly connected locking block 520 to move upward, so that the locking block 520 engages with the locking part 320 in the locking slide groove 310 at the bottom of the tray 300, thereby locking and fixing the tray 300 and preventing the tray 300 from sliding after entering the assembly station.

[0022] like Figure 3 and Figure 4 As shown, the locking groove 310 is located at the bottom of the tray 300 so that the locking block 520 can move along the corresponding locking groove 310. The locking groove 310 is provided with a locking part 320 with a toothed structure so that the locking block 520 engages with the locking part 320, thereby improving the locking and fixing stability of the tray 300.

[0023] like Figure 2 and Figure 3 As shown, four pulleys 330 are also installed at the bottom of the pallet 300, and each pulley 330 is engaged in pairs on the corresponding guide rails 650. The two guide rails 650 are installed on the conveyor frame 600 in a spaced-apart manner, so that each pulley 330 moves along the corresponding guide rail 650 as the pallet 300 moves along the conveyor frame 600, thereby improving the stability of the pallet 300.

[0024] The working principle of the circulating tray 300 positioning and locking conveying mechanism 100 of the valve assembly line of this utility model is as follows: During the cyclic assembly and conveying of valves by the conveying mechanism 100, the valves are placed on pallets 300. To ensure more precise delivery of the pallets 300 to the assembly station, positioning components 400 are installed at the bottom of each pallet 300. This activates the motor on the conveying component 200, which in turn drives two chains connected by meshing transmission gears to rotate. This, in turn, causes each pallet 300, which is screwed between the two chains, to rotate along the conveyor frame 600. During the conveying process, to improve the positioning accuracy of the pallets 300, the valves are positioned in the respective positioning slots... The sensor 640 at the front end of 610 senses the moving pallet 300, thereby causing the motor to decelerate. After the pallet 300 enters the assembly station, the positioning rod 410 on the positioning component 400 installed at the bottom of the pallet 300 rotates along the conveyor frame 600, thereby compressing the first elastic element 420 metal spring. During the recovery process after compression, the first elastic element 420 metal spring pushes the positioning rod 410 to engage in the positioning groove 610, thereby accurately positioning the pallet 300 during the conveying process and reducing the offset to ±1mm. Meanwhile, a locking button 620 is provided at the bottom of the positioning groove 610. After the positioning rod 410 is engaged in the positioning groove 610, pressing the locking button 620 will activate the two locking components 500 connected to the locking button 620. This will cause the telescopic drive 510 on each locking component 500 to drive the locking block 520 to move upward and engage with the locking part 320 provided at the bottom of the tray 300, thereby locking and fixing the tray 300 and preventing the tray 300 from sliding during valve assembly, thus improving the accuracy of valve delivery by the conveying mechanism 100.

[0025] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
