Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0023] Example: A feeding mechanism for a pressure sensor, including a main frame 1, as shown in the attached diagram. Figure 1As shown, the bottom of the main frame 1 is equipped with multiple adjustable feet 101 for adjusting the height of the main frame 1. The adjustable feet are threaded rods, and rotating the threaded rods adjusts the extension length of the adjustable feet, thereby adjusting the height of the entire main frame. The main frame 1 is equipped with a discharge movable slide 2 and a feed fixed slide 3 arranged vertically. A feed thrust assembly 4 is installed on the main frame 1 at the bottom of the outer end of the feed fixed slide 3. A positioning assembly 5 for positioning the material tray is installed above the inner end of the discharge movable slide 2. A discharge thrust assembly 6 is installed on the main frame 1 at the bottom of the discharge movable slide 2. A lifting assembly 7 for moving the material tray from the feed fixed slide 3 into the positioning assembly 5 is installed at one end of the main frame 1 at the inner end of the feed fixed slide 3. The lifting assembly 7 includes a straight plate 71 set at one end of the main frame 1. A lifting rodless cylinder 72 is provided on the inner side of the straight plate 71. A lifting seat 73 that moves between the positioning assembly 5 and the feeding fixed slide 3 is connected to the inner side of the straight plate 71 via a slider assembly. The moving end of the lifting rodless cylinder 72 is connected to the lifting seat 73. The lifting rodless cylinder drives the lifting seat to move up and down to realize the conveying of the material tray.

[0024] The feeding fixed slide 3 includes multiple uprights 31 arranged in rows on the main frame 1. The upper end of the uprights 31 is provided with clamping blocks 32, and the clamping blocks 32 are provided with horizontal shafts 33. The end of the horizontal shafts 33 is provided with track plates 34 for supporting the material tray. The material tray is mounted on the track plates. The structure is simple and saves costs.

[0025] The discharge chute 2 includes track fixing blocks 21 symmetrically arranged on the upper part of the main frame 1, as shown in the attached figure. Figure 3 As shown, a fixed track component 22 is installed on the inner side of the track fixing block 21; a first one-way tilting track component 23 corresponding to the end of the fixed track component 22 is installed on the upper part of the main frame 1; the discharge thrust component 6 is located below the fixed track component 22 and the first one-way tilting track component 23; a second one-way tilting track component 24 is provided at the upper end of the track fixing block 21; a lifting discharge cylinder 25 is provided on the upper part of the main frame 1 and below the fixed track component 22. The first one-way tilting track component 23 mainly includes a fixing plate 231, a fixing block 232 is provided on the fixing plate 231, a movable block 233 is hinged to one side of the fixing block 232, and a track piece 234 is connected to one side of the movable block 233, as shown in the attached figure. Figure 5As shown, the track plates can be flipped unidirectionally from bottom to top. When the lifting component sends the material tray into the positioning component, it passes through the first unidirectional flipping track component, causing the track plates on both sides to flip upwards. After the material tray passes, the track plates automatically reset. During the process of the lifting seat moving the empty material tray downwards, the material tray can be placed on the track plates. The structure of the second unidirectional flipping track component is the same as that of the first unidirectional flipping track component. There is a certain distance between the discharge height of the fixed track component and the actual height at which the worker can pick up the empty tray. The worker may need to bend over to pick up the empty tray. The second unidirectional flipping track component is designed to address this issue. The track components are mainly for facilitating the handling of empty pallets. When an empty pallet is moved onto a fixed track component, a lifting and discharging cylinder lifts the empty pallet up. Then, the track plates inside the second one-way flipping track component flip upwards and open. After the empty pallet is lifted to a certain height, the track plates on both sides return to their original positions, and the extended end of the lifting and discharging cylinder retracts, thus placing the empty pallet on the track plates. The upper part of the main frame 1 is provided with guide blocks 26 corresponding to the discharge end of the second one-way flipping track component 24. The outer side of the guide blocks 26 has limiting strips 27. The empty pallet slides within the limiting strips on both sides, and the guide blocks enable the smooth movement of the empty pallet.

[0026] The positioning component 5 includes two top plates 51 mounted on the main frame 1 and located above the first unidirectional tilting track component 23, as shown in the attached figure. Figure 4 As shown, the grooves on the top plate 51 together form a limiting groove 52, and multiple limiting plates 53 for positioning the material tray are installed at the opening of the limiting groove 52. The lifting seat sends the material tray into the limiting groove, and the edge of the material tray touches the limiting plate; the inner side of the straight plate 71 is provided with a limiting corner guard rail 74 corresponding to one end of the limiting groove 52, as shown in the attached figure. Figure 2 As shown, in order to ensure that the material tray can accurately enter the limiting groove, the tray can rise along the limiting corner guard track when the lifting seat drives the tray to rise.

[0027] The material tray is placed on the slide in a frame-like manner, and is therefore moved on the slide by a cylinder. The feeding thrust assembly 4 includes a rodless cylinder. The moving end of the rodless cylinder is connected to a clamping block, and a long rod is installed on the clamping block. Piston cylinders are set at both ends of the long rod, and the extended ends of the piston cylinders are connected to top columns. During feeding, the piston cylinders on both sides extend, and the rodless cylinder moves, causing the top columns to extend, which in turn moves the tray on the fixed feeding slide. When it approaches the lifting seat, the top column connected to the extended end of the piston cylinder at one end of the long rod retracts, and the rodless cylinder continues to move. Continuing operation, the piston cylinder at the other end of the long rod continues to drive the tray to move. The retracted piston cylinder moves below the lifting seat, and the top column on the extended piston cylinder engages with the arc groove at the end of the lifting seat, at which point the rodless cylinder stops. Then the lifting seat moves upward, thus removing the material tray. The structure of the discharge thrust assembly is similar to that of the feed thrust assembly, except for the structure of the moving end. The long rod at the moving end is equipped with a piston cylinder on only one side. The rodless cylinder moves to the inner end of the discharge sliding track, and the top column at the extended end of the piston cylinder extends. The rodless cylinder operates, and the top column drives the empty tray to move outward.

[0028] The working principle of this utility model is as follows: A material tray with multiple pressure sensors is placed at the outer end of the fixed feeding slide. The feeding thrust component sends the material tray to the inner end of the fixed feeding slide. Then, the lifting component lifts the material tray into the positioning component, and the material tray is effectively positioned, thus enabling material grabbing. The empty material tray is then moved down to the discharge movable slide by the lifting component. The discharge thrust component drives the empty material tray to move towards the outer end of the discharge movable slide. This utility model, by setting the feeding and discharging in upper and lower layers, provides ample material handling space and a reasonable spatial arrangement, which helps to improve work efficiency.
