Description

TECHNICAL FIELD

[0001] The utility model relates to a limiting device technical field, especially a limiting device and transmission equipment. BACKGROUND

[0002] In the related art, a blocking rod structure is usually arranged in a transmission line. Specifically, when a carrier moves along the transmission direction of the transmission line, the blocking rod structure is used to extend towards the front of the carrier to stop the carrier from continuing to transmit on the transmission line, so that the carrier can be intercepted at a specific position on the transmission line to facilitate the execution of steps such as loading and grabbing. At present, in order to ensure smooth movement of the carrier, the left and right sides of the carrier usually do not have substantial contact with the transmission line. Therefore, when the blocking rod structure intercepts the carrier, the carrier is usually only limited by the contact of the blocking rod structure at its front end, and accurate limiting of the carrier cannot be achieved, which may cause the carrier to be misaligned or tilted.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0050] It should be noted that if the embodiments of the utility model involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0052] In related technologies, a stop lever structure is usually arranged in a transmission pipeline. Specifically, when a carrier moves along the transmission direction of the transmission pipeline, the stop lever structure is used to protrude towards the front of the carrier to stop the carrier from continuing to move on the transmission pipeline, so that the carrier can be intercepted at a specific position on the transmission pipeline to facilitate the execution of steps such as loading and grabbing on the carrier. At present, in order to ensure smooth movement of the carrier, the left and right sides of the carrier usually do not have substantial contact with the transmission pipeline, so when the stop lever structure intercepts the carrier, the carrier is usually only limited by the contact of the stop lever structure at the front end, and accurate limiting of the carrier cannot be achieved, which causes the risk of deviation and dumping of the carrier.

[0053] The utility model provides a limiting device 100.

[0054] Please refer toFigures 1 to 6 In an embodiment of the present application, the limiting device 100 is applied to a transmission flow line 300, the transmission flow line 300 is used for transmitting a carrier 200, a limiting station is formed on the transmission flow line 300, the transmission direction of the transmission flow line 300 is defined as a first direction, and the limiting device 100 comprises:

[0055] A limiting mechanism 10 is arranged on one side of the limiting station, the limiting mechanism 10 comprises a first limiting structure 11 and a second limiting structure 12 arranged adjacent to the limiting station, the first limiting structure 11 and the second limiting structure 12 both extend along a second direction perpendicular to the first direction and are oppositely arranged in the first direction, and the limiting mechanism 10 further comprises a third limiting structure 13 arranged between the first limiting structure 11 and the second limiting structure 12 and extending along the first direction;

[0056] A guiding mechanism 20 is arranged on the side of the limiting station away from the limiting mechanism 10, the guiding mechanism 20 extends along the first direction and is oppositely arranged with the third limiting structure 13 in the second direction; and

[0057] A driving mechanism 30 is drivingly connected with the limiting mechanism 10 and used for driving the limiting mechanism 10 to extend or retract towards or away from the limiting station, so that the limiting mechanism 10 has an extended state and a retracted state.

[0058] When the limiting mechanism 10 is in the extended state, the first limiting structure 11 and the second limiting structure 12 are used for stopping on the opposite sides of the carrier 200 in the first direction respectively, and the third limiting structure 13 and the guiding mechanism 20 are used for stopping on the opposite sides of the carrier 200 in the second direction respectively.

[0059] Specifically, the first limiting structure 11, the second limiting structure 12 and the third limiting structure 13 are all movably arranged relative to the limiting station to have an active stroke extending to the limiting station. The side of the first limiting structure 11 towards the second limiting structure 12 can be arranged as a plane, an arc surface having a guiding function, or a shape profiled with the front side of the carrier 200, so as to cooperate with the carrier 200 for limiting. Similarly, the side of the second limiting structure 12 towards the first limiting structure 11 can be arranged as a plane, an arc surface or a shape profiled with the rear side of the carrier 200, and the opposite surfaces of the third limiting structure 13 and the guiding mechanism 20 in the second direction can be arranged as planes, arc surfaces or respectively profiled with the left and right sides of the carrier 200, which will not be described herein.

[0060] In some embodiments, the driving mechanism 30 can be provided with a driving member 31, which can drive the first limiting structure 11, the second limiting structure 12 and the third limiting structure 13 to move towards or away from the limiting station simultaneously; in this way, one-to-many driving design can be realized, which is beneficial to reduce the occupied volume of the driving structure and can reduce the energy consumption of the driving mechanism 30 to a certain extent. Alternatively, the driving mechanism 30 can also be provided with three driving members 31, which are respectively in transmission connection with the first limiting structure 11, the second limiting structure 12 and the third limiting structure 13, so as to drive the first limiting structure 11, the second limiting structure 12 and the third limiting structure 13 to move towards or away from the limiting station respectively; in this way, many-to-many driving design can be realized, which is beneficial to improve the movement flexibility of each limiting structure in the limiting mechanism 10. Of course, the technical solution of the present application is not limited to this, for example, the first limiting structure 11 and the second limiting structure 12 can also be in transmission connection with the same driving member 31, while the third limiting structure 13 can be in transmission connection with another driving member 31; in this way, the first limiting structure 11 and the second limiting structure 12 can be moved simultaneously at first, so as to contact and limit the carrier 200 moved to the limiting station in the first direction, and then the third limiting structure 13 cooperates with the guide mechanism 20 to contact and limit the carrier 200 in the second direction. The specific implementation can be set according to actual needs, which is not limited here.

[0061] Further, the driving member 31 of the driving mechanism 30 can be configured as a telescopic cylinder, a screw driving mechanism or the like linear driving mechanism, so that the first limiting structure 11, the second limiting structure 12 or the third limiting structure 13 can be extended into or withdrawn from the limiting station in a translational manner. Alternatively, the driving member 31 of the driving mechanism 30 can also be configured as a rotary motor or the like rotary driving mechanism, so that the first limiting structure 11, the second limiting structure 12 or the third limiting structure 13 can be extended into or withdrawn from the limiting station in a rotational manner. Of course, the driving mechanism 30 can also include a linear driving mechanism and a rotary driving mechanism at the same time, which is not limited here.

[0062] It should be noted that by movably arranging the first limiting structure 11 and the second limiting structure 12 relative to the limiting station, the first limiting structure 11 and the second limiting structure 12 can be extended towards the limiting station, so as to realize the stop limiting of the carrier 200 on the opposite sides in the first direction. By movably arranging the third limiting structure 13 relative to the limiting station, the third limiting structure 13 can be moved towards or away from the guide mechanism 20, so as to realize the stop limiting of the carrier 200 on the opposite sides in the second direction in cooperation with the guide mechanism 20.

[0063] Further, the guide mechanism 20 can be fixed relative to the limiting station, and when the third limiting structure 13 is driven by the driving mechanism 30 to extend towards the limiting station, the distance between the guide mechanism 20 and the third limiting structure 13 in the second direction is shortened, so that the guide mechanism 20 and the third limiting structure 13 can be clamped on the opposite sides of the carrier 200 in the second direction. In this way, the guide mechanism 20 can realize the limiting function of the carrier 200 in cooperation with the third limiting structure 13 without additional driving structure.

[0064] In some embodiments, the guide mechanism 20 can also be retractable relative to the limiting station, and when the third limiting structure 13 is driven by the driving mechanism 30 to extend towards the limiting station, the guide mechanism 20 can also extend towards the limiting station, so that the third limiting structure 13 and the guide mechanism 20 can be moved towards each other in the second direction, the distance between the third limiting structure 13 and the guide mechanism 20 in the second direction is shortened, and then the third limiting structure 13 and the guide mechanism 20 can be clamped on the opposite sides of the carrier 200 in the second direction. In this way, not only the limiting function of the carrier 200 can be realized, but also the movement stroke of the guide mechanism 20 and the third limiting structure 13 can be adjusted to control the different positions of the carrier 200 in the second direction. After the carrier 200 is limited in the second direction by moving the third limiting structure 13 and the guide mechanism 20 towards each other, and the carrier 200 completes the filling and other steps, the third limiting structure 13 and the guide mechanism 20 are controlled to move away from each other in the second direction, the distance between the third limiting structure 13 and the guide mechanism 20 in the second direction is increased, and then the third limiting structure 13 and the guide mechanism 20 can be separated from the opposite sides of the carrier 200 in the second direction at the same time, so that the carrier 200 can be released.

[0065] The technical scheme of the utility model discloses a limiting device 100 including limiting mechanism 10, guide mechanism 20 and drive mechanism 30, wherein, limiting mechanism and guide mechanism are along second direction and divide to be located at the opposite sides of limiting station, drive mechanism 30 is used to drive limiting mechanism to move towards or away from guide mechanism 20, to make limiting structure have the state of extension and retraction. Among them, limiting mechanism 10 includes first limiting structure 11 and second limiting structure 12 that are relatively spaced apart in the first direction, when the limiting structure is in the state of extension, first limiting structure 11 and second limiting structure 12 can be stopped on the opposite sides of carrier 200 in the first direction respectively. Limiting mechanism 10 further includes third limiting structure 13 arranged between first limiting structure 11 and second limiting structure 12, by setting third limiting structure 13, and make third limiting structure 13 and guide mechanism 20 relatively arranged along the second direction, when the limiting structure is in the state of extension, third limiting structure 13 and guide mechanism 20 can be stopped on the opposite sides of carrier 200 in the second direction respectively. So set, when limiting mechanism 10 is in the state of extension, limiting mechanism 10 and guide mechanism 20 can realize the abutment limiting of the circumferential side of carrier 200 cooperatively, and then the limiting stability of carrier 200 can be improved through the circumferential limiting of carrier 200.

[0066] Please refer to Figures 2 to 6 In the embodiment of the utility model, the limiting mechanism 10 further includes connecting plate 14, the connecting plate 14 is arranged on one side of the limiting station and is in transmission connection with the drive mechanism 30, for telescopic movement towards or away from the limiting station under the drive of the drive mechanism 30;

[0067] The first limiting structure 11, the second limiting structure 12 and the third limiting structure 13 are arranged on the connecting plate 14 respectively and protrude from the connecting plate 14 towards the limiting station.

[0068] So set, the mounting base of first limiting structure 11, second limiting structure 12 and third limiting structure 13 can be formed through connecting plate 14, so that first limiting structure 11, second limiting structure 12 and third limiting structure 13 can form an integral whole through connecting plate 14 and move towards or away from the limiting station synchronously under the drive of the drive mechanism 30.

[0069] Further, please refer to Figures 4 to 6 In the embodiment of the utility model, the first limiting structure 11 includes first limiting part 111, the second limiting structure 12 includes second limiting part 121, and the first limiting part 111 and the second limiting part 121 protrude from the side of the connecting plate 14 facing the limiting station;

[0070] The length of the first limiting part 111 in the second direction is D1, and the length of the second limiting part 121 in the second direction is D2, wherein D1>D2.

[0071] Thus, since the first limiting part 111 and the second limiting part 121 are effective limiting parts of the first limiting structure 11 and the second limiting structure 12 respectively, and the length of the first limiting part 111 in the second direction is greater than that of the second limiting part 121, when the first limiting part 111 and the second limiting part 121 are driven by the driving mechanism 30 to extend towards the limiting station synchronously, the first limiting part 111 can enter the limiting station earlier than the second limiting part 121.

[0072] Specifically, when the limiting mechanism 10 moves from the retracted state to the extended state, the limiting mechanism 10 has an initial position, a first extended position and a second extended position arranged in sequence in the active stroke. When the limiting mechanism 10 is at the initial position, the first limiting structure 11 and the second limiting structure 12 are both located outside the limiting station, at this time the carrier 200 can be normally transported on the transmission line 300 along the transmission direction to smoothly pass through the limiting station; when the limiting mechanism 10 is at the first extended position, the first limiting structure 11 enters the limiting station, and the second limiting structure 12 is located outside the limiting station, at this time only the first limiting structure 11 can play a role of contact limiting for the carrier 200, the carrier 200 can pass through the side of the second limiting structure 12 first and then stop on the first limiting structure 11, so that the carrier 200 can smoothly enter and intercept in the limiting station; when the limiting mechanism 10 is at the second extended position, at this time the first limiting structure 11 and the second limiting structure 12 both enter the limiting station and can respectively contact and limit the carrier 200 on the two opposite sides in the first direction.

[0073] Please refer to Figures 4 to 6 In the embodiment of the utility model, the side of the second limiting part 121 facing the first limiting part 111 has a limiting surface 121a, the limiting surface 121a extends in the direction from the connecting plate 14 to the guiding mechanism 20 and is arranged in the direction away from the first limiting structure 11.

[0074] The limiting surface 121a can have the function of limiting and guiding, in the process of the second limiting structure 12 extending towards the limiting station, the limiting surface 121a can enter the limiting station first, if the carrier 200 in the limiting station has a certain degree of inclination at this time, the carrier 200 can abut against the limiting surface 121a and restore to the normal position through the movement of the limiting surface 121a, so as to guarantee the limiting effect of the limiting mechanism 10 on the carrier 200 in the first direction.

[0075] Please refer to Figures 4 to 6In an embodiment of this utility model, the end of the third limiting structure 13 facing the guide mechanism 20 is elastically telescopically arranged in the second direction for elastically contacting the carrier 200.

[0076] This configuration avoids hard contact between the third limiting mechanism 10 and the carrier 200 when it extends, thereby reducing the risk of motor overload and step loss in the drive mechanism 30 and ensuring full, gapless contact with the carrier 200 to achieve precise positioning.

[0077] Please see Figures 4 to 6 In an embodiment of this utility model, the third limiting structure 13 includes:

[0078] A pressure plate 131 is disposed on one side surface of the connecting plate 14 and forms a telescopic channel with the connecting plate 14, the telescopic channel extending along the second direction; and

[0079] Top block 132 is elastically and telescopically mounted on the telescopic channel via an elastic element. At least a portion of the top block 132 protrudes from the side of the connecting plate 14 facing the limiting station and is used to elastically abut against the carrier 200.

[0080] In this design, by setting a pressure plate 131 on the connecting plate 14 to press and fix the top block 132, the telescopic channel formed by the pressure plate 131 and the connecting plate 14 can guide and limit the top block 132. The telescopic channel formed by the pressure plate 131 and the connecting plate 14 can be through at both ends, or it can be through only at the end facing the limiting position; no limitation is made here. To reduce the manufacturing cost of the third limiting structure 13, a spring can be selected as the elastic element.

[0081] In some embodiments, the top block 132 includes a first connecting portion 132a and a second connecting portion 132b connected sequentially in a second direction. The second connecting portion 132b is elastically and telescopically installed within the telescopic channel. The side of the first connecting portion 132a opposite to the second connecting portion 132b is used to cooperate with the guide mechanism 20 to collaboratively limit the opposite sides of the carrier 200 in the second direction. Specifically, the cross-sectional area of ​​the first connecting portion 132a is larger than the cross-sectional area of ​​the telescopic channel. On the one hand, this allows the first connecting portion 132a to stop outside the telescopic channel, thus limiting the retraction stroke of the top block 132. On the other hand, it ensures that there is sufficient contact area between the first connecting portion 132a and the carrier 200 so that the third limiting structure 13 can abut against and limit the carrier 200.

[0082] Further, on the basis that the cross-sectional area of the first connecting portion 132a is greater than the cross-sectional area of the telescopic channel, at least part of the first connecting portion 132a can be arranged opposite to the side edge of the connecting plate 14, and the elastic member is clamped between the first connecting portion 132a and the connecting plate 14, so that the first connecting portion 132a and the connecting plate 14 are elastically connected through the elastic member, so as to realize the elastic telescopic design of the top block 132. Wherein, a mounting hole can be arranged on the side of the first connecting portion 132a facing the connecting plate 14, and the end of the elastic member is limited in the mounting hole, so as to limit the installation of the elastic member through the top block 132, thereby improving the installation stability of the elastic member; the mounting hole can also be arranged on the side of the connecting plate 14 facing the first connecting portion 132a, so as to limit the installation of the elastic member through the connecting plate 14. Of course, the connecting plate 14 and the first connecting portion 132a can also be respectively provided with a first mounting hole and a second mounting hole, and the first mounting hole and the second mounting hole are arranged opposite to each other, and the two ends of the elastic member are respectively limited in the first mounting hole and the second mounting hole, so as to limit the elastic member through the connecting plate 14 and the first connecting portion 132a, thereby facilitating further improving the installation stability of the elastic member.

[0083] Of course, the technical scheme of the utility model is not limited to this, in another possible implementation mode, the second connecting portion 132b can also be connected with the elastic member. For example, the telescopic channel formed by the pressing plate 131 and the connecting plate 14 can be only provided through at one end facing the limiting station, the elastic member is accommodated in the telescopic channel and located at the end of the second connecting portion 132b away from the first connecting portion, so that the two ends of the elastic member are respectively in contact with the end wall of the telescopic channel and the end of the second connecting portion 132b, thereby realizing the elastic telescopic design of the top block 132. The specific implementation mode can be set according to actual needs, which is not limited here.

[0085] In this way, when the pressing plate 131 and the top block 132 move relatively, the limiting groove 132c can guide the limiting block 131a, thereby improving the movement stability between the pressing plate 131 and the top block 132. On this basis, the length of the limiting groove 132c can be limited to limit the stroke of the top block 132.

[0086] Further, in an available embodiment, the top block 132 is provided with a limiting groove 132c, and the pressing plate 131 is provided with a limiting block 131a which can be a screw, capable of being arranged in the limiting groove 132c and being threadedly connected with the connecting plate 14.

[0087] Please refer to Figures 3 to 6 In the embodiment of the utility model, the connecting plate 14 is provided with a rack 141, and the driving mechanism 30 comprises:

[0088] The driving member 31 comprises an output shaft which is rotatably arranged; and

[0089] The gear 32 is sleeved on the output shaft and is in meshing transmission with the rack 141.

[0090] The gear 32 is used for driving the rack 141 to drive the connecting plate 14 to extend or retract towards or away from the limiting station when the output shaft is driven to rotate forward or reversely.

[0091] The driving member 31 can be a rotary motor, and the output shaft thereof is arranged adjacent to the connecting plate 14 and is rotatably arranged around the first direction. By arranging the gear 32 on the output shaft of the driving member 31 and arranging the rack 141 extending along the second direction on the connecting plate 14, and making the gear 32 and the rack 141 in meshing transmission, when the driving shaft drives the gear 32 to rotate forward around the first direction, the rack 141 can drive the connecting plate 14 to extend along the first direction towards the limiting station, so as to drive the limiting mechanism 10 to move to the extended state; and when the driving shaft drives the gear 32 to rotate reversely around the first direction, the rack 141 can drive the connecting plate 14 to retract along the first direction away from the limiting station, so as to drive the limiting mechanism 10 to move to the retracted state. The driving mode is not limited to motor driving, and can also be cylinder or electric push rod driving, etc., directly fixed with the connecting plate 14 to drive the connecting plate 14 to extend or retract.

[0092] Further, please refer to Figure 4 and Figure 5 In the embodiment of the utility model, the limiting mechanism 10 further comprises a guide rail 15 which is arranged on one side of the connecting plate 14 and extends along the second direction and is in sliding connection with the connecting plate 14. In this way, the movement stability of the limiting mechanism 10 can be improved by the guiding effect of the guide rail 15 on the connecting plate 14. The guiding mode is not limited to guide rail, and can also be sliding groove or linear bearing guiding, etc.

[0093] Please refer to Figures 2 to 5In the embodiment of the utility model, the limiting device 100 further includes a material arrival detection mechanism 40, and the material arrival detection mechanism 40 is used for detecting whether the carrier 200 exists in the limiting station.

[0094] In this way, the limiting device 100 can control the movement state of the limiting mechanism 10 according to whether the carrier 200 exists in the limiting station, so as to better limit the carrier 200.

[0095] Specifically, when the limiting mechanism 10 is at the first extended position, the first limiting structure 11 enters the limiting station, and the second limiting structure 12 is located outside the limiting station, at this time, only the first limiting structure 11 can contact and limit the carrier 200, and the carrier 200 can pass through the side of the second limiting structure 12 on the transmission assembly line 300 first, and then stop on the first limiting structure 11, so that the carrier 200 can smoothly enter and intercept the limiting station. On this basis, when the material arrival detection mechanism 40 detects that the carrier 200 intercepted by the first limiting structure 11 exists in the limiting station, the limiting device 100 can control the limiting mechanism 10 to move from the first extended position to the second extended position, so as to further move to the extended state, thereby completing the complete contact and limitation of the carrier 200 on the two opposite sides in the first direction.

[0096] The material arrival detection mechanism 40 can realize material arrival detection through a non-contact detection mode, for example, in some embodiments, the material arrival detection mechanism 40 can be arranged as a photoelectric detector or a photographing detection mechanism, which can be arranged adjacent to the first limiting structure 11 and arranged in a spaced manner opposite to the limiting station, and the detection end is arranged towards the limiting station, so as to timely detect the interception of the carrier 200 by the first limiting structure 11. Alternatively, the material arrival detection mechanism 40 can also realize material arrival detection through a contact detection mode, for example, in some embodiments, the material arrival detection mechanism 40 can be arranged as a pressure sensor, which can be arranged on the first limiting part 111 of the first limiting structure 11, and is used for contacting the carrier 200 when the first limiting structure 11 intercepts the carrier 200, so as to realize material arrival detection. The specific implementation can be arranged according to actual needs, which is not limited here.

[0097] In the embodiment of the utility model, the limiting device 100 further includes a material arrival detection mechanism 40, and the material arrival detection mechanism 40 is used for detecting whether the carrier 200 exists in the limiting station.

[0098] In some embodiments, the position detection mechanism 50 can be provided as an inductive switch 51 and an inductive sheet 52, the inductive sheet 52 being connected to the connecting plate 14 of the limiting mechanism 10 for synchronous movement with the limiting mechanism 10; the inductive switch 51 being located on the moving path of the inductive sheet 52 for being triggered by the inductive sheet 52 when the inductive sheet 52 moves to its sensing position. Specifically, the inductive switch 51 can be provided with only one for detecting whether the limiting mechanism 10 is in the extended state or the retracted state; the inductive switch 51 can also be provided with two for respectively detecting whether the limiting mechanism 10 is in the extended state and the retracted state; further, when the limiting mechanism 10 moves from the retracted state to the extended state and has an initial position, a first extended position and a second extended position provided in sequence on its activity stroke, three inductive switches 51 can be provided, and each inductive switch 51 corresponds to a position.

[0099] Please refer to Figure 7 The utility model also proposes a control method of the limiting device 100, the specific structure of the limiting device 100 refers to the above embodiment, because the control method of the limiting device 100 adopts all the technical schemes of the above all embodiments, so it has all the beneficial effects brought by the technical schemes of the above embodiments at least, here will not repeat.

[0100] The control method of the limiting device 100 comprises the following steps:

[0101] S10, control the first limiting structure 11 to extend towards the limiting station, so that the first limiting structure 11 enters the limiting station to intercept the carrier 200.

[0102] S20, when the first limiting structure 11 intercepts the carrier 200, control the second limiting structure 12 to enter the limiting station, so that the limiting device 100 limits the carrier 200 along the first direction;

[0103] S30, control the third limiting structure 13 to enter the limiting station, to drive the carrier 200 to move along the second direction towards the guide mechanism 20, so that the limiting device 100 limits the carrier 200 along the second direction.

[0104] In the embodiment, the first limiting structure 11 needs to enter the limiting station before the second limiting structure 12, at this time, the second limiting structure 12 can release the carrier 200, and the first limiting structure 11 can intercept the carrier 200, so that the carrier 200 can smoothly enter the limiting station and be intercepted in the limiting station. It should be noted that the interception of the carrier 200 can be realized by making at least part of the first limiting structure 11 enter the limiting station. The movement stroke of the first limiting structure 11 can be controlled by controlling the driving mechanism 30.

[0105] In some embodiments, the first limiting structure 11 and the second limiting structure 12 can be driven by different driving members 31 in the driving mechanism 30 respectively, that is, when the first limiting structure 11 extends towards the limiting station, the second limiting structure 12 can remain stationary. On this basis, the second limiting structure 12 can be driven to extend towards the limiting station after the first limiting part 111 of the first limiting structure 11 completely enters the limiting station. Alternatively, the first limiting structure 11 can be driven to move further towards the limiting station after partially entering the limiting station to preliminarily intercept the carrier 200, while the second limiting structure 12 also extends towards the limiting station, which is beneficial to shorten the time for the first limiting structure 11 and the second limiting structure 12 to completely limit the carrier 200 and improve the limiting efficiency.

[0106] Of course, the technical scheme of the utility model is not limited thereto, and in some embodiments, the first limiting structure 11 and the second limiting structure 12 can also be driven by the same driving member 31 in the driving mechanism 30 simultaneously. On this basis, the length of the first limiting part 111 of the first limiting structure 11 in the second direction needs to be greater than the length of the second limiting structure 12 in the second direction, so that when the first limiting structure 11 and the second limiting structure 12 move synchronously, the first limiting structure 11 can enter the limiting station earlier than the second limiting structure 12.

[0107] Further, after the first limiting structure 11 enters the limiting station earlier than the second limiting structure 12, the carrier 200 can be directly intercepted when the carrier 200 exists in the limiting station to preliminarily limit the carrier 200 in the limiting station. When the first limiting structure 11 intercepts the carrier 200, the second limiting structure 12 is controlled to enter the limiting station, which can avoid the second limiting structure 12 entering the limiting station when the carrier 200 does not completely enter the limiting station, so that the carrier 200 cannot normally enter the limiting station.

[0108] Further, after the first limiting structure 11 and the second limiting structure 12 both enter the limiting station to complete the contact limiting of the carrier 200 on the two sides opposite in the first direction, the third limiting structure 13 is driven to extend towards the limiting station to contact and limit the carrier 200 in the second direction, which can avoid the position of the carrier 200 in the first direction deviating when the carrier 200 moves in the second direction, so that better limiting effect can be achieved.

[0109] The utility model discloses still put forward a kind of transmission equipment 1000, including transmission assembly line 300 and limiting device 100, the specific structure of this limiting device 100 refers to above-mentioned embodiment, since the transmission assembly line 300 of the present application adopts all technical solutions of above-mentioned all embodiments, thus at least have all beneficial effects brought by the technical scheme of above-mentioned embodiment, here no longer repeat.

[0110] The above-mentioned is only the exemplary embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and the contents of the drawings, or direct / indirect application in other related technical fields are included in the patent protection range of the utility model.
