Then the material removal claw moves horizontally and places the semi-finished product on the stacking station.

[0003] In order to further improve the efficiency of product picking and stacking, the applicant applied for a material picking device of a product picking machine on the same day, including a product picking and transferring mechanism that can move up and down and left and right between the product picking station and the stacking station, and is characterized in that: the product picking and transferring mechanism includes a moving seat, a toothed claw conveying unit and an inclined conveying unit; the moving seat, on both sides of which are respectively provided with a toothed claw conveying unit and an inclined conveying unit; the toothed claw conveying unit includes a plurality of parallel teeth for picking products and a conveying bar for conveying materials to the inclined conveying unit, the conveying bar is wound on the parallel teeth, and one side of the parallel teeth is provided with a driving wheel for driving the conveying bar to operate, and the toothed claw conveying unit faces the product picking station; the inclined conveying unit, whose feeding end is higher than the discharging end, the conveying direction of the inclined conveying unit is the same as that of the toothed claw conveying unit, and the inclined conveying unit faces the stacking station.

[0004] The conveyor bar and inclined conveyor unit work together during the movement of the moving base to further move the material and increase the material movement speed. However, the conveyor bar is prone to wear and even breakage during long-term use and needs to be replaced promptly. If the entire toothed conveyor unit is replaced, the maintenance cost is high and the replacement operation is difficult. Summary of the Invention

[0005] The utility model aims to solve the shortcomings of the prior art and provides a conveniently replaceable material taking device for a product taking machine, which reduces maintenance costs and facilitates the replacement of conveyor strips.

[0006] To solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] A material-picking device for a sample-picking machine that is easy to maintain includes a movable seat and a tooth-claw conveying mechanism, wherein the movable seat can move along the X-axis and Y-axis directions, and the tooth-claw conveying mechanism is arranged on the movable seat; the tooth-claw conveying mechanism includes parallel teeth, a transmission bar and a roller transmission assembly with a power source; the parallel teeth are arranged at intervals on the movable seat; the transmission bar is wound around the parallel teeth, and the transmission bar is used to drive the material from the parallel tooth inlet end to the parallel tooth outlet end; the roller transmission assembly includes rollers distributed along the axial direction, and the rollers are used to drive the transmission bar to operate, and the rollers have a first transmission part and a second transmission part on both sides, and the first transmission part is mechanically matched with the adjacent second transmission part.

[0022] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0023] See Figure 1-Figure 3 A material-retrieving device for a product-retrieving machine that is easy to maintain includes a movable base 1 and a toothed claw conveying mechanism 2. The movable base 1 can move up and down and left and right. The toothed claw conveying mechanism 2 is mounted on the movable base 1 and includes parallel teeth 21, a conveying bar 22, and a roller transmission assembly 3 with a power source. The parallel teeth 21 are spaced apart on the movable base 1. To facilitate assembly and subsequent maintenance, the parallel teeth 21 are detachably mounted on the movable base 1. A support frame is bolted to the movable base 1, which is threadedly connected to the side surfaces of the parallel teeth 21. The upper and lower side surfaces of the parallel teeth 21 provide the movement of the conveying bar 22. The conveying bar 22 is wound around the parallel teeth 21. The conveying bar 22 is used to drive the material from the feeding end of the parallel teeth 21 to the discharging end of the parallel teeth 21. The moving seat 1 can drive the parallel teeth 21 to enter the gap between the lower ejector pins in the product removal station to remove the product, that is, the parallel teeth 21 move horizontally into the gap between the lower ejector pins, and then the parallel teeth 21 rise to remove the product, so that the material is placed on the placing plane composed of several parallel teeth 21. Several conveying bars 22 are in contact with the bottom surface of the material. The operation of the conveying bar 22 drives the material to move. The discharging end of the claw conveying mechanism 2 is connected with an inclined conveying mechanism for releasing the material into the stacking station.

[0024] The roller transmission assembly 3 includes axially distributed rollers 31, which are used to drive the conveyor bar 22. A first transmission portion 32 and a second transmission portion 33 are located on either side of the roller 31. The first transmission portion 32 mechanically cooperates with the adjacent second transmission portion 33. Each roller 31 in the roller transmission assembly 3 is independent, and transmission between the rollers 31 is achieved through mechanical coordination between the first transmission portion 32 and the adjacent second transmission portion 33. When the conveyor bar 22 wears out and needs replacement, the corresponding roller 31 can be removed and the conveyor bar 22 replaced, eliminating the need for complete replacement. This reduces maintenance costs and simplifies operation.

[0025] There are many mechanical transmission modes between the rollers 31: for example, see Figure 4 and Figure 5 , the first transmission part 32 is a groove shaft, the second transmission part 33 is a convex shaft, the first transmission part 32 is engaged with the adjacent second transmission part 33, or the first transmission part 32 is connected with the adjacent second transmission part 33 through a separate coupling. Specifically, a positioning part is provided on the movable seat 1, and the positioning part includes an upper recessed block 41 and a lower recessed block 42. The upper recessed block 41 and the lower recessed block 42 are connected to form a positioning cavity 43. The first transmission part 32 of the roller 31 is connected with the adjacent second transmission part 33 to form a coupling part. The coupling part is arranged in the positioning cavity 43. The first transmission part 32 and the second transmission part 33 are installed in the positioning cavity 43 through a ball bearing 5. The positioning part can support the roller 31 and position the coupling part at the same time. The positioning cavity 43 ensures transmission stability and avoids misalignment between the first transmission part 32 and the second transmission part 33.

[0026] See Figure 5 To facilitate processing, the roller 31 includes a fixed component 311 and a mounting plate 312. The first transmission portion 32 and the second transmission portion 33 are disposed on either side of the fixed component 311. The mounting plate 312 is detachably mounted on the fixing plate. The detachable mounting plate is easily mounted on the fixed component 311, allowing the roller 31 to be assembled in a split manner. This split design facilitates processing and maintenance. A retaining ring groove 313 is formed between the mounting plate 312 and the fixing plate. The retaining ring groove 313 limits the position of the conveyor bar 22 and ensures that the conveyor bar 22 remains in the correct position during operation, reducing deviation. Example 1

[0027] The roller 31 has a grooved shaft and a protruding shaft on either side, which engage and connect to form a coupling component. A lower recessed block 42 is assembled on the movable base 1. Ball bearings 5 are assembled where the grooved shaft and the protruding shaft contact the lower recessed block 42. The upper recessed block 41 is threadedly connected to the lower recessed block 42, forming a positioning cavity 43 between the upper and lower recessed blocks 41 and 42. The coupling component is disposed within the positioning cavity 43. The roller 31 consists of a fixed component 311 and a mounting plate component 312. The grooved shaft and the protruding shaft are disposed on either side of the fixed component 311. The mounting plate component 312 is removably mounted on the fixed component 311. A retaining ring groove 313 is formed between the mounting plate component 312 and the fixed portion. The conveyor bar 22 is assembled within the retaining ring groove 313. The power source drives the roller 311 to rotate, driving the conveyor bar 22 to move around the parallel teeth 21, thereby moving the material.

[0028] When the conveying bar 22 needs to be replaced, only the upper recessed block 41 and the corresponding roller 31 need to be disassembled to remove the conveying bar 22 for replacement. The maintenance cost is low and the operation is simple. Example 2

[0029] The structure of the roller 31 and the operation of the conveyor bar 22 are the same as those in Example 1. The roller 31 has a first transmission portion 32 and a second transmission portion 33 on either side. The first transmission portion 32 and the second transmission portion 33 serve as transmission shafts. The transmission shafts between adjacent rollers 31 are connected and transmitted via a split coupling, which is installed in the positioning cavity 43.

[0030] When the conveying bar 22 needs to be replaced, it is only necessary to dismantle the corresponding upper recessed block 41, the separable coupling and the corresponding roller 31, and then the conveying bar 22 can be dismantled and replaced, which has low maintenance cost and simple operation.
