Wherein the first driving member 21 is fixed to the top end of the vertical plate portion 123 of the side plate 12 via the L-shaped stay 23. The link frame 23 includes a first bracket 231 and a second bracket 232 in an L-shape; the first bracket 231 is composed of a first vertical plate and a transverse plate, and the second bracket 232 is composed of a second vertical plate and a longitudinal plate; the longitudinal plate of the second bracket 232 is fixedly connected with the transverse plate of the first bracket 231; the power output end of the first driving member 21 is connected to the first vertical plate of the first bracket 231, and the head end of the driving shaft 22 extends out of the side plate 12 and is connected to the second vertical plate of the second bracket 232. The first slide rail assembly 24 includes first sliders 241 (2 are arranged at intervals) fixed on the top plate 13 and first slide rails 242 slidably engaged with the first sliders 241, and one end of the first slide rails 242 is connected to the transverse plate of the first bracket 231. Meanwhile, the top ends of the vertical plates 123 of the two side plates 12 are provided with U-shaped notches 121 for the first sliding rails 242 to slide through. Here, the first slide rail assembly 24 is reversely installed, the first slider 241 is fixed, and the first slide rail 242 moves. The first slide rail 242 is used for supporting the driving shaft 22 extending out of the side plate 12, so that the stability of the driving shaft 22 can be better kept, and the twisting and blocking caused by unbalanced stress can be prevented. In short, the connecting frame 23 is driven by the first driving member 21 to perform a reciprocating linear motion, and the connecting frame 23 drives the driving shaft 22 to perform a synchronous motion.

The step stopper 3 is fixedly installed between the lateral plate portions 122 of the two side plates 12 below the driving shaft 22; two step stoppers 3 are arranged in parallel.

One of them year thing interval piece 4 is fixed in the end of drive shaft 22, and other year thing interval pieces 4 (5) activity cover are established on drive shaft 22, and the bottom of adjacent year thing interval piece 4 has the difference in height (can obviously be seen in figure 10) with ladder dog 3 looks adaptation, and a plurality of year thing interval piece 4 is laminated each other and is separated under drive shaft 22's drive to the interval between the adjacent year thing interval piece 4 of adjustment.

In addition, an elastic limiting column 7 for buffering and limiting the connecting frame 23 is arranged on the vertical plate part 123 of the side plate 12 close to the connecting frame 23; the head of the elastic limiting column 7 corresponds to the position of the transverse plate of the first bracket 231.

The supporting shaft 5 plays a supporting and guiding role for the inter-carrier distance block 4.

As shown in fig. 5 to 8, the driving shaft 22 forms a plurality of first steps 221 (in this embodiment, 6 inter-carrier distance blocks 4, one of which is fixedly installed, and the other five of which are movably installed, so that 5 first steps 221 are formed in this embodiment), each first step 221 includes a first step surface 2211 and a first vertical surface 2212 intersecting with the first step surface 2211; the top of the step stopper 3 forms a plurality of second steps 31 (the fixed mounted inter-carrier distance block 4 needs to be limited, so in this embodiment, 6 second steps 31 are formed), and each second step 31 includes a second step surface 311 parallel to the extending direction of the driving shaft 22 and a second vertical surface 312 staggered with the second step surface 311.

Whether or not the equal intervals are separated depends on the lengths of the first step surface 2211 and the second step surface 311. How many products 9 are separated depends on the number of first steps 221 and second steps 31.

The following is an example of a mechanism for achieving equal-pitch separation:

all the first step surfaces 2211 are equal in length, the height difference between the adjacent first step surfaces 2211 is equal, all the second step surfaces 311 are equal in length, and the height difference between the adjacent second step surfaces 311 is equal. The drive shaft 22 tapers in radial dimension from head end to tail end; the height of the second step surface 311 of the step stopper 3 increases in order in the extending direction of the drive shaft 22.

Each mounting hole 46 of the movably mounted object spacing block 4 for the driving shaft 22 to pass through is matched with a corresponding first step surface 2211; when the object spacing blocks 4 are separated from each other, one side 41 of each object spacing block 4 is closely attached to a corresponding first vertical surface 2212, the other side 42 is closely attached to a corresponding second vertical surface 312, and the bottom of each object spacing block 4 is attached to a corresponding second step surface 311.

In this embodiment, in order to further optimize the technical solution, a second driving mechanism 8 is further added; the second driving mechanism 8 includes a second driving member 81 and a second slide rail assembly 82. The second slide rail assembly 82 includes a second slide block 821 arranged on the bottom plate 11 of the rack 1 and a second slide rail 822 in sliding fit with the second slide block 821, and the second slide rail 822 is used for being fixed with a platform on which the rack 1 is placed; the second driving member 81 is connected to the bottom plate 11 by a connecting plate 83, and is used for driving the frame 1 and the mechanisms and components mounted on the frame 1 to slide along the second sliding rail 822, so as to leave a space for the grasping mechanism (not shown in the figure) to grasp the product.

The first driving member 21 and the second driving member 81 may be any members capable of performing a linear motion, such as an air cylinder, an electric push rod, and a linear motor.

The working principle of the utility model is briefly explained below (taking the situation of matching the pushing mechanism, grabbing the mechanism as an example):

and (3) restoring the initial state, and restoring the process from the step 1 to the step 9: when the driving shaft 22 moves in a direction departing from the rack 1 under the driving of the first driving member 21, each first step 221 of the driving shaft 22 does not act on the object-carrying distance block 4 movably mounted thereon, and when the driving shaft moves for a certain distance, the object-carrying distance block 4 fixedly mounted (the last one is defaulted) is attached to the adjacent object-carrying distance block 4 movably mounted thereon and then can be pushed to move synchronously; then, all the object carrying distance blocks 4 are mutually attached, and the first movable object carrying distance block 4 is attached to the inner wall of the side plate 12; at the moment, the pushing mechanism pushes the products 9 to the object carrying distance block 4, and the products 9 are adsorbed in the notches 43 of the object carrying distance block 4.

Performing a gapped state, from the process of fig. 9 to fig. 1: when the driving shaft 22 moves towards the direction of the frame 1 under the driving of the first driving member 21, each first step 221 of the driving shaft 22 is acted, when the first elevation 2212 of the first step 221 contacts with the side portion 41 (see fig. 7) of the corresponding inter-carrier distance block 4, the movably mounted inter-carrier distance block 4 is sequentially pushed to move synchronously (the rear side of the fixed inter-carrier distance block 4 is pushed at first) until the inter-carrier distance block 4 moves to the position defined by the second elevation 312 of the corresponding second step 31 of the step stopper 3; a plurality of inter-item spacing blocks 4 are separated from each other and positioned between the corresponding first and

second elevation surfaces

2212 and 312, enabling adjustment of the spacing of the products 9. The gripping mechanism then grips the product 9 away.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
