Description

Technical Field

[0001] The invention relates to a bottle clamping mechanism and a bottle taking device. Background Art

[0002] In order to ensure the quality of milk, it is necessary to test the milk quality regularly so that problems can be found and solved in time. During the testing process, two steps need to be completed, namely, testing the milk and cleaning the sampling bottles after testing. The sampling bottles are generally placed in the sample tray for milk testing. After the milk testing is completed, the sampling bottles in the sample tray need to be transferred to the cleaning tray for cleaning through the bottle removal device.

[0003] The bottle picking device includes a plurality of bottle clamping mechanisms arranged in a straight line. The bottle picking device clamps the sampling bottles arranged in a straight line on the sample tray through the plurality of bottle clamping mechanisms, so as to transfer the sampling bottles from the moving sample tray to the cleaning tray for cleaning. The bottle clamping mechanism in the prior art generally includes two movable clamping claws. The driving cylinder drives the two movable clamping claws through the transmission connecting rod to swing close to clamp the sampling bottle and swing away to release the sampling bottle, so as to achieve the clamping and placement of the sampling bottle. However, when the two movable clamping claws of the bottle clamping mechanism swing away, the space occupied is relatively large. When the size of the bottle picking device is the same, the number of bottle clamping mechanisms installed on the bottle picking device is relatively small, resulting in a small number of sampling bottles transferred by the bottle picking device at one time, affecting the work efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a bottle clamping mechanism to solve the technical problem that the two movable clamping claws of the bottle clamping mechanism in the prior art occupy a large space when they swing away; the purpose of the present invention is also to provide a bottle picking device to solve the technical problem that the two movable clamping claws of the bottle clamping mechanism in the prior art occupy a large space when they swing away, and when the size of the bottle picking device is the same, the number of bottle clamping mechanisms assembled on the bottle picking device is relatively small, resulting in a small number of sampling bottles transported by the bottle picking device at one time.

[0005] To achieve the above object, the technical solution of the bottle clamping mechanism of the present invention is:

[0006] The bottle clamping mechanism comprises a fixed clamping jaw extending in the front-to-back direction, and a fixed clamping section at the front end; a movable clamping jaw extending in the front-to-back direction, and a guide assembly on the fixed clamping jaw that can reciprocate along a straight line in the left-right direction; a movable clamping jaw having a movable clamping section at the front end, and the movable clamping jaw and the fixed clamping jaw being arranged opposite to each other in the left-right direction, so that when the movable clamping jaw approaches the fixed clamping jaw, the movable clamping jaw cooperates with the fixed clamping jaw to clamp the sampling bottle; a transmission connection part is provided on the movable clamping jaw, which is used for transmission connection with a driving member that drives the movable clamping jaw to move;

[0007] A driving plate and a guide plate, wherein the driving plate and the fixed clamp are matched in upper limit positions in the front-to-rear direction and in guide sliding cooperation in the left-to-right direction, and a guide plate rail is provided on the guide plate for corresponding guide sliding cooperation with the fixed clamp, and the left-right spacing at the rear ends of two adjacent guide plate rails is greater than the left-right spacing at the front ends, or the left-right spacing at the rear ends of two adjacent guide plate rails is less than the left-right spacing at the front ends.

[0008] The beneficial effect is: the guide for the movable jaw to reciprocate along a straight line is assembled on the fixed jaw, so that the clamping section of the movable jaw cooperates with the clamping section of the fixed jaw to clamp the sampling bottle when it is close to the clamping section of the fixed jaw, and releases the sampling bottle when the clamping section of the movable jaw is away from the clamping section of the fixed jaw, so as to realize the clamping and putting down of the sampling bottle by the bottle clamping mechanism. Compared with the swinging, the reciprocating stroke of the movable jaw in the left and right directions occupies less space. When the size of the bottle picking device is the same, the number of bottle clamping mechanisms assembled on the bottle picking device is relatively large, so that the bottle picking device can transport more sampling bottles at one time, thereby improving work efficiency.

[0009] The movable clamp is an elastic clamp. When the elastic clamp cooperates with the fixed clamp to clamp the sampling bottle, the elastic clamp can better clamp the sampling bottle between the elastic clamp and the fixed clamp by relying on its own elasticity.

[0010] The transmission connection part is a wire-pull connection part, which is used to connect with the wire-pull transmission to make the elastic clip close to the fixed jaw, the wire-pull constitutes the driving member, and a compression spring is provided between the fixed jaw and the elastic clip, which is used to apply an elastic force to the elastic clip to make it away from the fixed jaw; or the transmission connection part is a wire-pull connection part, which is used to connect with the wire-pull transmission to make the elastic clip away from the fixed jaw, the wire-pull constitutes the driving member, and a tension spring is provided between the fixed jaw and the elastic clip, which is used to apply an elastic force to the elastic clip to make it close to the fixed jaw. Since the wire-pull is a flexible wire, the elastic clip is driven to move toward the fixed jaw by the wire-pull, which facilitates the arrangement of a driving device for driving the wire-pull action on the base.

[0011] A guide rod extending in the left-right direction is provided between the elastic clip and the fixed jaw, so that the elastic clip can be reciprocated in a straight line in the left-right direction and is assembled on the fixed jaw, two guide rods are arranged at intervals in the front-back direction, and the pull wire connection part is arranged between the two guide rods. The elastic clip is prevented from being deflected during the movement toward the fixed jaw, so that the elastic clip and the fixed jaw can better clamp the sampling bottle.

[0012] The movable claw clamping section includes a bending portion at its front end bent toward the fixed claw clamping section. The bending portion can limit the position of the sampling bottle in the forward direction, and after the movable clamping section and the fixed clamping section clamp the sampling bottle, the sampling bottle is prevented from moving forward.

[0013] The elastic clip is a straight piece extending in the front-to-back direction, or the movable claw clamping section includes a bent portion at its front end bent toward the fixed claw clamping section, and the remaining portion of the elastic clip behind the bent portion is a straight section extending in the front-to-back direction. Designing the elastic clip as a straight piece or the main body as a straight section not only facilitates the processing of the elastic clip, but also ensures that the elastic clip has a certain strength.

[0014] To achieve the above purpose, the technical solution of the bottle taking device of the present invention is:

[0015] The bottle-taking device comprises a base, a fixed clamping jaw, a movable clamping jaw and a driving member, and a driving plate and a guide plate are arranged on the base; at least two fixed clamping jaws are arranged on the base at intervals along the left-right direction, and each fixed clamping jaw extends along the front-back direction, and has a fixed clamping section at the front end; at least two movable clamping jaws are arranged and correspond to the fixed clamping jaws one by one, and each movable clamping jaw extends along the front-back direction, and is assembled on the corresponding fixed clamping jaw along a straight line in the left-right direction; the movable clamping jaw has a movable clamping section that cooperates with the fixed clamping section of the corresponding fixed clamping jaw The movable claw clamping section and the fixed claw clamping section are arranged opposite to each other in the left and right directions, so that when the movable claw approaches the fixed claw, it cooperates with the fixed claw clamping section to clamp the sampling bottle; the driving member is transmission-connected to the movable claw to drive the movable claw to move; the driving plate and the fixed claw cooperate in upper limit positioning in the front-to-back direction and guide sliding cooperation in the left-to-right direction, and the guide plate is provided with a guide plate rail corresponding to the fixed claw for guiding sliding cooperation, and the left-right spacing of the rear ends of the two adjacent guide plate rails is greater than the left-right spacing of the front ends, or the left-right spacing of the rear ends of the two adjacent guide plate rails is less than the left-right spacing of the front ends.

[0016] The beneficial effect is: the guide for the movable jaw to reciprocate along a straight line is assembled on the fixed jaw or on the base, so that the clamping section of the movable jaw cooperates with the fixed jaw clamping section to clamp the sampling bottle when it is close to the fixed jaw clamping section, and releases the sampling bottle when the movable jaw clamping section is away from the fixed jaw clamping section, so as to realize the clamping and putting down of the sampling bottle by the bottle clamping mechanism. Compared with the swinging, the reciprocating stroke of the movable jaw in the left and right directions occupies less space. When the size of the bottle picking device is the same, the number of bottle clamping mechanisms assembled on the bottle picking device is relatively large, so that the bottle picking device can transport more sampling bottles at one time, thereby improving work efficiency.

[0017] The movable clamp is an elastic clamp. When the elastic clamp cooperates with the fixed clamp to clamp the sampling bottle, the elastic clamp can better clamp the sampling bottle between the elastic clamp and the fixed clamp by relying on its own elasticity.

[0018] The guide assembly of the elastic clip that can reciprocate in a straight line in the left and right directions is mounted on the corresponding fixed jaw, the driving member is a pull wire that is connected to the elastic clip in a transmission manner, and is used to drive the elastic clip to approach the fixed jaw, and a compression spring is provided between the fixed jaw and the elastic clip, and is used to apply an elastic force to the elastic clip to make it move away from the fixed jaw; the driving member is a pull wire that is connected to the elastic clip in a transmission manner, and is used to drive the elastic clip to move away from the fixed jaw, and a tension spring is provided between the fixed jaw and the elastic clip, and is used to apply an elastic force to the elastic clip to make it move toward the fixed jaw. Since the pull wire is a flexible wire, the elastic clip is driven to move toward the fixed jaw by the pull wire, which facilitates the arrangement of a driving device for driving the pull wire action on the base.

[0019] A guide rod extending in the left-right direction is provided between the elastic clip and the fixed jaw, so that the elastic clip can be reciprocated in a straight line in the left-right direction and is assembled on the fixed jaw, two guide rods are arranged at intervals in the front-back direction, and the wire connecting part on the elastic clip for connecting with the wire transmission is arranged between the two guide rods. The elastic clip is prevented from deflecting during the movement toward the fixed jaw, so that the elastic clip and the fixed jaw can better clamp the sampling bottle.

[0020] Each pull wire shares a driving cylinder, so that each pull wire drives the corresponding elastic clip to move closer to or away from the fixed clamping claw. Since each pull wire shares a driving cylinder, the number of cylinders is reduced, the structure of the bottle picking device is simplified, the cost is reduced, and the weight of the bottle picking device is reduced, which is conducive to the transfer device driving the bottle picking device to move.

[0021] The movable claw clamping section includes a bending portion at its front end bent toward the fixed claw clamping section. The bending portion can limit the position of the sampling bottle in the forward direction, and prevent the sampling bottle from moving forward after the movable claw clamping section and the fixed claw clamping section clamp the sampling bottle.

[0022] The elastic clip is a straight piece extending in the front-to-back direction, or the movable claw clamping section includes a bent portion at its front end bent toward the fixed claw clamping section, and the remaining portion of the elastic clip behind the bent portion is a straight section extending in the front-to-back direction. Designing the elastic clip as a straight piece or the main body as a straight section not only facilitates the processing of the elastic clip, but also ensures that the elastic clip has a certain strength.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] The specific embodiment of the bottle taking device of the present invention is as follows Figure 1 and Figure 2As shown, the bottle-taking device includes a base 1, on which a driving plate 3 and a guide plate 2 are arranged at intervals in the up-down direction, and both the driving plate 3 and the guide plate 2 extend in the left-right direction. The guide plate 2 is fixed to the base 1 through its two ends, and the driving plate 3 is assembled on the base 1 in a reciprocating guiding and sliding manner in the front-back direction. The bottle-taking device also includes a plurality of bottle-clamping mechanisms, each of which is arranged at intervals in the left-right direction, the front end of the bottle-clamping mechanism is a cantilevered clamping end, and the rear end is assembled between the driving plate 3 and the guide plate 2, the rear end of the bottle-clamping mechanism cooperates with the driving plate 3 in the front-back direction to limit the bottle-clamping mechanism to move forward and backward with the driving plate 3, and the rear end of the bottle-clamping mechanism cooperates with the driving plate 3 in the left-right direction. A guide plate guide rail is provided on the guide plate 2, which corresponds to the bottle-clamping mechanism in a one-to-one guiding and sliding manner, so as to guide the bottle-clamping mechanism to move forward and backward with the driving plate 3, and the left-right spacing of the rear ends of two adjacent guide plate guide rails is greater than the left-right spacing of the front ends, wherein the left-right spacing of the rear end is 50 mm, and the left-right spacing of the front end is 40 mm. In other embodiments, two adjacent guide plates may be designed so that the left-right spacing at the rear end of the guide rail is smaller than the left-right spacing at the front end as needed.

[0035] Specifically, Figure 3 , Figure 5 and Figure 8 As shown, the guide rail of the guide plate is a guide long hole 19, and each bottle clamping mechanism is provided with a slider 18 on the side facing the guide plate 2. The slider 18 is guided and slidably matched with the guide long hole 19 to achieve the guided and slidable match between the bottle clamping mechanism and the guide rail of the guide plate. The guide long hole is easy to process, which reduces the processing cost. In other embodiments, the guide rail of the guide plate can be a guide long groove, and the guide long groove is guided and slidably matched with the slider; or the guide rail of the guide plate is a guide plate protrusion, and each bottle clamping mechanism is provided with a guide groove on the side facing the guide plate. The slider 18 is a cylinder, so that the slider 18 and the guide long hole 19 can be guided and slidably matched.

[0036] In this embodiment, the guide long hole 19 is an inclined hole. Specifically, the distance between two adjacent guide long holes 19 in the left-right direction gradually decreases from the back to the front. The inclined hole is relatively smooth, which is conducive to the reciprocating movement of the bottle clamping mechanism between the front and rear ends. In other embodiments, the guide long hole is an arc hole; or the guide long hole includes a straight hole section and an inclined hole section. Figure 5As shown, the guide long hole 19 is a step hole structure, the slider 18 slides on the step of the guide long hole 19, and the bottle clamping mechanism is supported on the guide plate 2 only by the slider 18 to prevent the entire bottle clamping mechanism from sliding on the guide plate and increasing the friction. In other embodiments, when the friction between the opposite sides of the guide plate and the bottle clamping mechanism is small, the step structure may not be provided, and the slider and the guide long hole only play a guiding role to allow the bottle clamping mechanism to slide on the guide plate. In this embodiment, the number of guide long holes 19 is ten, and they are symmetrically distributed on the guide plate 2. The distance between the rear ends of any two adjacent wire long holes 19 in the left-right direction is the same, and the distance between the front ends of any two guide long holes 19 in the left-right direction is the same. In other embodiments, the number of guide long holes is set as needed, and the distance between the rear ends of two adjacent guide long holes in the left-right direction and the distance between the rear ends of two adjacent guide long holes in the left-right direction can be set as needed.

[0037] like Figure 1 , Figure 6 and Figure 7 As shown, the driving plate 3 is provided with a guide protrusion 21 extending in the left-right direction, and the corresponding rear end of the bottle clamping mechanism is provided with a second slide rail 23, and the second slide rail 23 is provided with a guide groove that is in sliding cooperation with the guide protrusion 21, so as to achieve the guiding and sliding cooperation between the rear end of the bottle clamping mechanism and the driving plate 3 in the left-right direction. Through the cooperation between the guide groove and the guide protrusion 21, it is convenient for the rear end of the bottle clamping mechanism to slide on the driving plate 3. In other embodiments, a guide groove extending in the left-right direction may be provided on the driving plate, and the corresponding rear end of the bottle clamping mechanism is provided with a guide protrusion that is in sliding cooperation with the guide groove.

[0038] In this embodiment, the driving plate 3 is arranged above the guide plate 2, the guide protrusion 21 is a dovetail protrusion, and the guide groove is a dovetail groove, so that the bottle clamping mechanism is hung on the driving plate when the dovetail protrusion and the dovetail groove are guided and slidably matched. In order to ensure the stability of the bottle clamping mechanism, the driving plate 3 is generally made wider in the front-to-back direction. Since the driving plate 3 is a plate that can move back and forth in the front-to-back direction, it is arranged above to avoid collision with the placement frame of the sampling bottle during the forward sliding process. At the same time, the dovetail groove and the dovetail protrusion can not only realize the guided sliding, but also realize the bottle clamping mechanism being hung on the driving plate 3, which simplifies the structure. In addition, by pre-hanging each bottle clamping mechanism on the driving plate 3, it is also convenient for the overall assembly of the bottle taking device. In other embodiments, the driving plate can be arranged below the guide plate. At this time, the driving plate needs to be made narrower in the front-to-back direction to avoid collision with the sampling bottle placement frame when the bottle clamping mechanism is driven to clamp the sampling bottle, thereby affecting the grabbing of the sampling bottle. It should be noted that the sample tray and the cleaning tray are both sampling bottle placement trays.

[0039] like Figure 1As shown, a cylinder seat 6 is provided on the base 1 for fixing and installing a cylinder (not shown), a cylinder top push seat 5 is fixedly provided on the drive plate 3, a cylinder body of the cylinder is fixedly installed on the cylinder seat 6, a telescopic rod of the cylinder is fixedly installed on the cylinder top push seat 5, and the cylinder drives the cylinder top push seat 5 to move forward and backward through the telescopic rod, thereby driving the drive plate 3 to move back and forth. In this embodiment, two cylinder seats 6 are arranged at intervals, and two cylinder top push seats 5 are fixedly provided on the corresponding drive plate 3 to ensure the stability of the cylinder driving the drive plate to move back and forth in the front and back directions. In other embodiments, it can be driven manually, and after the drive plate is driven into place, it is locked in this position by a latch. At this time, it is time-consuming and labor-intensive, and is not conducive to automated production. In other embodiments, an electric push rod can be fixedly installed on the base to drive the drive plate to move back and forth.

[0040] like Figure 1 and Figure 6 As shown, the upper side of the driving plate 3 is provided with a first slide rail 20, and the first slide rail 20 is provided with a slide groove extending in the front-to-back direction. There are two first slide rails 20, which are respectively arranged at the left and right ends of the driving plate 3. The base 1 is provided with a guide seat 4, and the lower side of the guide seat 4 is provided with a sliding protrusion that slides with the slide groove to achieve the reciprocating movement of the driving plate 3 on the base 1 in the front-to-back direction. In other embodiments, sliding protrusions or slide grooves can be provided on the end surfaces of both ends of the driving plate, and the corresponding ends of the base corresponding to the driving plate are provided with slide grooves or sliding protrusions.

[0041] like Figure 1 , Figure 7 and Figure 8 As shown, the bottle clamping mechanism includes a fixed clamping jaw 7 and a movable clamping jaw 8 arranged at intervals along the left and right directions, the fixed clamping jaw 7 and the movable clamping jaw 8 both extend along the front-back direction, the movable clamping jaw 8 is assembled on the fixed clamping jaw 7 along a straight line reciprocating guide, the front end of the fixed clamping jaw 7 has a fixed clamping section 25, the front end of the movable clamping jaw 8 has a movable clamping section 26, the movable clamping section 26 and the fixed clamping section 25 are arranged relative to each other along the left and right directions, so that when the movable clamping jaw 8 approaches the fixed clamping jaw 7, it cooperates with the fixed clamping section 25 to clamp the sampling bottle, and compared with the swing, the reciprocating stroke of the movable clamping jaw 8 in the left and right directions occupies less space, and when the size of the bottle picking device is the same, the number of bottle clamping mechanisms assembled on the bottle picking device is relatively large, so that the number of sampling bottles transported by the bottle picking device at one time is large, and the work efficiency is improved. In other embodiments, the movable clamping jaw and the fixed clamping jaw are assembled on the base, and the movable clamping jaw is assembled on the base along a straight line reciprocating guide.

[0042] In this embodiment, the movable clamping jaw 8 is an elastic clamping piece, and the fixed clamping jaw 7 has a clamping recess. When the elastic clamping piece cooperates with the fixed clamping jaw 7 to clamp the sampling bottle, the elastic clamping piece can better clamp the sampling bottle on the clamping recess of the fixed clamping jaw 7 by relying on its own elasticity. In other embodiments, the movable clamping jaw is an active clamping block extending in the front-to-back direction, and the active clamping block is not elastic.

[0043] The movable jaw 8 is connected to a pull wire for pulling the movable jaw 8 toward the fixed jaw 7, so that the movable jaw 8 cooperates with the fixed jaw 7 to clamp the sampling bottle. A compression spring (not shown) is provided between the movable jaw 8 and the fixed jaw 7 to apply a force away from the fixed jaw 7 to the movable jaw 8 after the pull wire is released, so that the movable jaw 8 and the fixed jaw 7 release the sampling bottle. Since the pull wire is a flexible wire, the movable jaw 8 is driven to move toward the fixed jaw 7 by the pull wire, so it is convenient to arrange a driving device for driving the pull wire action on the base 1. In other embodiments, a tension spring is provided between the movable jaw and the fixed jaw to apply an elastic force to the movable jaw close to the fixed jaw, so that the movable jaw cooperates with the fixed jaw to clamp the sampling bottle. The movable jaw is connected to a pull wire for pulling the movable jaw away from the fixed jaw, so that after the pull wire is tightened, a force away from the fixed jaw is applied to the movable jaw, so that the movable jaw and the fixed jaw release the sampling bottle. In other embodiments, the movable clamping claws of each bottle clamping mechanism are fixed on a driving rod, and the driving rod can be directly driven by a cylinder to drive each movable clamping claw to reciprocate, so that all bottle clamping mechanisms can clamp and release the sampling bottle.

[0044] Specifically, take one of the pull wires as an example, Figure 1 As shown, the pull wire includes a core body 13 and a protective cover 14 sleeved on the core body 13. One end of the core body 13 passes through the pull wire groove 9 and the pull wire hole 24 and is fixed on the pull wire fixing hole 22. The pull wire fixing hole 22 constitutes a pull wire connection part. At the same time, one end of the protective cover 14 is fixed in the pull wire groove 9; the other end of the core body 13 passes through the protective cover fixing seat 10 and is fixed on the core body fixing seat 11. At the same time, the other end of the protective cover 14 is fixed on the protective cover fixing seat 10. Figure 1 and Figure 4 As shown, a vertical plate 17 is provided on the base 1, and the core fixing seat 11 and the protective cover fixing seat 10 are both fixed on the vertical plate 17; wherein, a wire-driven cylinder 12 is also fixed on the vertical plate 17, and a transmission plate 15 is fixed on the telescopic rod of the wire-driven cylinder 12, and the transmission plate 15 is fixedly connected to the core fixing seat, so that when the telescopic rod of the wire-driven cylinder 12 is extended and retracted, the transmission plate 15 is driven to drive the core fixing seat 11 to move, and then drive the wire to pull the movable clamping claw, so that the movable clamping claw 8 cooperates with the fixed clamping claw 7 to clamp the sampling bottle. In other embodiments, the movable clamping claws of each bottle clamping mechanism can be fixed on a driving rod, and in this case, only one wire is needed to pull one movable clamping claw to realize that all bottle clamping mechanisms can clamp the sampling bottle.

[0045] In this embodiment, each bottle clamping mechanism is provided with a pull wire, and the other pull wires are not drawn. Each pull wire shares a pull wire driving cylinder 12, which reduces the number of cylinders, simplifies the structure of the bottle picking device, reduces the cost, and reduces the weight of the bottle picking device, which is conducive to the transfer device driving the bottle picking device to move. Specifically, the same end of the core of each pull wire is fixed on the core body fixing seat 11, and the core body fixing seat 11 is fixedly connected to the transmission plate 15. The pull wire driving cylinder 12 only needs to drive the transmission plate 15 to drive each pull wire to move. In other embodiments, each pull wire connected to the movable clamping claw can be equipped with a driving cylinder, or two pull wires can share a driving cylinder.

[0046] like Figure 7 and Figure 8 As shown, the fixed jaw 7 is provided with a guide rod 16, and two guide rods 16 are arranged at intervals along the front-to-back direction to guide the movable jaw 8 during the reciprocating movement of the movable jaw 8. The compression spring (not shown) is sleeved on the guide rod 16, which is not only convenient for the assembly of the compression spring, but also can prevent the movable jaw 8 from deflecting during the movement of the fixed jaw 7, so as to ensure that the movable jaw 8 and the fixed jaw 7 can better clamp the sampling bottle. In other embodiments, the compression spring can be arranged on the side of the guide rod, and at this time, the two ends of the compression spring are fixedly connected to the movable jaw and the fixed jaw respectively. Specifically, the guide rod 16 is slidably assembled on the fixed jaw 7, and the end of the guide rod 16 is fixedly connected to the movable jaw. In other embodiments, the guide rod is fixed on the fixed jaw, and the movable jaw guide is slidably assembled on the guide rod. A limiting structure, such as a limiting protrusion, is provided on the guide rod on the side of the movable jaw away from the fixed jaw to prevent the movable jaw from sliding out of the guide rod. In other embodiments, the guide rod may not be provided, and a guide hole extending in the left-right direction is provided on the fixed clamping jaw, and the guide assembly of the movable clamping jaw that can reciprocate in the left-right direction is installed in the guide hole of the fixed clamping jaw. Among them, the pull wire fixing hole 22 is provided between the two guide rods 16 to ensure the stability of the pull wire during the pulling process.

[0047] In this embodiment, the movable claw clamping section 26 includes a bent portion 27 at its front end bent toward the fixed claw clamping section 25, and the remaining portion of the movable claw 8 behind the bent portion 27 is a straight section extending in the front-to-back direction. By providing the bent portion 27, the sampling bottle can be limited in the forward direction, and the sampling bottle is prevented from moving forward after the movable claw clamping section 26 and the fixed claw clamping section 25 clamp the sampling bottle. In other embodiments, the movable claw can be directly designed as a straight piece extending in the front-to-back direction; or the movable claw clamping section includes a bent portion at its front end bent toward the fixed claw clamping section, and the remaining portion of the movable claw behind the bent portion is an arc-shaped section extending in the front-to-back direction.

[0048] When in use, the cylinder on the cylinder seat 6 drives the driving plate 3 to move backward, and the bottle clamping mechanism slides to the rear end of the guide slot 19 through the slider 18. At this time, the center distance between the two sliders 18 is 50 mm. The bottle picking device is moved to the bottle picking position of the sample tray (not shown), so that each bottle clamping mechanism corresponds to each sampling bottle 28, and then the pull wire is pulled by the pull wire driving cylinder 12 to drive the movable clamping jaw 8 to move closer to the fixed clamping jaw 7, as shown in FIG. Fig. 9 As shown, the movable claw clamping section 26 of the movable clamping jaw 8 and the fixed claw clamping section 25 of the fixed clamping jaw 7 cooperate to clamp the sampling bottle 28, and the upper side surfaces of the movable claw clamping section 26 and the fixed claw clamping section 25 are supported and cooperated with the edge 29 of the sampling bottle 28, ensuring the stability of the bottle clamping mechanism when clamping the sampling bottle, and the sampling bottle 28 on the sample plate can be taken away at this time. The bottle picking device is moved to the cleaning plate (not shown) by the motion device. During the movement, the cylinder on the driving cylinder seat 6 drives the driving plate 3 to move forward, and the bottle clamping mechanism slides to the front end of the guide long hole 19 through the slider 18. At this time, the center distance between the two sliders 18 is 40mm, and then the sampling bottle 28 is placed in the cleaning plate by the motion device, and the pull line driving cylinder 12 is opened to make the pull line loosen the movable clamping jaw 8 to release the clamping of the sampling bottle 28, completing a transportation process. It should be noted that the motion device of the transport bottle picking device can move the bottle picking device in the vertical direction and the horizontal direction to ensure that the bottle picking device can move the sampling bottle from the sample plate to the cleaning plate.
