Description

Technical Field

[0001] The utility model relates to the technical field of warehousing transportation, in particular to an adjusting mechanism and an in-place detection device. Background Technique

[0002] The distribution vehicle is applied in an industrial production line and can linearly move along a guide rail to convey the products it carries and transports to a plurality of workstations arranged along the guide rail, so as to provide products for the plurality of workstations, so that workers can pick up the products at the workstations and process them.

[0003] In order to perform in-place detection on the distribution vehicle, ranging components are arranged at corresponding positions of the guide rail for each workstation. When the distribution vehicle moves along the guide rail and triggers the ranging component, it is considered that the distribution vehicle has reached the workstation. However, if the distance between the ranging component and the distribution vehicle is too far, it is easy to cause the distribution vehicle to fail to trigger the ranging component even when it reaches the corresponding workstation. If the distance between the ranging component and the distribution vehicle is too close, it is easy to cause the distribution vehicle to collide with the ranging component and damage the ranging component. Therefore, in actual operation, the position of the ranging component on the guide rail needs to be accurately set.

[0004] In the prior art, the ranging component is usually fixed to the guide rail through a positioning block. Specifically, a kidney-shaped hole extending in the vertical direction is provided on the positioning block, and a fixing screw can pass through the kidney-shaped hole and be screwed onto the guide rail to fix the ranging component to the guide rail. When the setting height of the ranging component needs to be adjusted, workers need to repeatedly debug to ensure that the distance between the ranging component and the distribution vehicle can meet the use requirements. This adjustment method is inefficient, cumbersome in operation, and the workload of workers is large. Content of the Utility Model

[0005] The purpose of the utility model is to provide an adjusting mechanism and an in-place detection device, which can simplify the operation steps, reduce the adjustment difficulty, and further improve the convenience of adjusting the position of the ranging component of the distribution vehicle.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] In the first aspect, an adjusting mechanism is provided for adjusting the position of a detection component relative to a guide rail in a first direction. The adjusting mechanism is characterized in that it includes:

[0016] Preferably, the number of the clamping members is multiple, and the multiple clamping members are arranged at intervals in the second direction, and the second direction is parallel to the length direction of the guide rail.

[0017] Preferably, the clamping assembly further includes a second slide rail, which is arranged on the clamping member body and extends in the second direction, and the clamping member is slidably engaged with the second slide rail.

[0018] Preferably, the clamping member includes a first clamping portion and a second clamping portion which are oppositely arranged, and the distance between the first clamping portion and the second clamping portion is adjustable.

[0019] Preferably, the clamping member further includes a connecting portion, one end of the connecting portion is fixedly connected to the second clamping portion, and the first clamping portion is adjustably connected to the other end of the connecting portion.

[0020] Preferably, the adjustment mechanism further includes an adjustment detection member, which is arranged on the frame and used to detect the distance between it and the detection assembly.

[0026] The beneficial effects of the present utility model:

[0027] The adjustment mechanism provided by the present utility model can provide an overall support and a reference platform for the adjustment member and the clamping assembly by fixedly arranging the frame relative to the guide rail. By connecting one end of the adjustment member to the clamping assembly and screwing the other end to the frame, when the adjustment member is rotated, the clamping assembly and the detection assembly clamped by it can be driven to move in the first direction, thereby realizing the position adjustment of the detection assembly relative to the guide rail in the first direction. Compared with the prior art in which workers directly manually adjust the detection assembly, since the adjustment member is threadedly connected to the frame, when the worker rotates the adjustment member, the moving distance of the adjustment member in the first direction can be known according to the number of turns of the adjustment member, so as to realize a relatively accurate position adjustment of the detection assembly in the first direction.

[0038] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0039] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0041] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] Figure 1 The structural schematic diagram of the in-place detection device provided in this embodiment in cooperation with the guide rail is shown, as Figure 1As shown in the figure, this embodiment provides a position-in-place detection device, which is applied to the distribution vehicle production line. Among them, the distribution vehicle production line includes a distribution vehicle (not shown in the figure), a guide rail 100, a detection component 200, and a locking member 300. The distribution vehicle is slidably engaged with the guide rail 100 and can move along the length direction of the guide rail 100. The detection component 200 includes a fixing member 201 and a position-in-place detection member 202. The position-in-place detection member 202 can be triggered by the distribution vehicle to determine whether the distribution vehicle has reached the work station. The position-in-place detection member 202 is arranged on the fixing member 201, and the fixing member 201 is arranged on the guide rail 100 with adjustable position along the first direction, so as to adjust the position of the detection component 200 relative to the guide rail 100. The locking member 300 can lock the relative position between the fixing member 201 and the guide rail 100, so as to prevent the relative position between the guide rail 100 and the fixing member 201 from changing when the distribution vehicle moves on the guide rail 100, which affects the detection accuracy of the position-in-place detection member 202. In this embodiment, the position-in-place detection member 202 is a distance sensor or a proximity switch. Both the distance sensor and the proximity switch are relatively common detection members in the field, and the specific structures and working principles of the distance sensor and the proximity switch will not be elaborated in this embodiment.

[0043] Specifically, a kidney-shaped hole extending along the first direction is provided on the fixing member 201, and a connection hole is provided on the guide rail 100. The locking member 300 can pass through the kidney-shaped hole and be connected to the connection hole. In the prior art, the steps for adjusting the position of the detection component 200 relative to the guide rail 100 in the first direction are as follows: loosen the locking member 300 so that the fixing member 201 can move relative to the guide rail 100 in the first direction; manually adjust the position of the fixing member 201 relative to the guide rail 100 in the first direction, so as to adjust the position of the detection component 200 relative to the distribution vehicle, so that the position-in-place detection member 202 can stably detect the distribution vehicle and can avoid the distribution vehicle when the distribution vehicle slides along the guide rail 100 to prevent collision with the distribution vehicle; when the fixing member 201 is adjusted to the appropriate position, tighten the locking member 300. Optionally, in this embodiment, the locking member 300 is a fastening screw, and the connection hole is a threaded hole. The screw connection has the advantages of firm connection and convenient disassembly and assembly.

[0044] However, in actual operation, when it is necessary to adjust the position of the detection component 200 relative to the guide rail 100, the worker needs to rely on work experience to judge whether the distance between the position-in-place detection member 200 and the distribution vehicle can meet the use requirements. This adjustment method is extremely dependent on personal experience and has low efficiency.

[0045] For ease of description, as Figure 1 shown, the length direction of the guide rail 100 is defined as the second direction, and the height direction of the guide rail 100 is defined as the first direction. The first direction and the second direction are perpendicular to each other.

[0046] Figure 2The structural schematic diagram of the adjustment mechanism provided in this embodiment is shown. As Figures 1 to 2 shown, the adjustment mechanism includes a frame 1, a clamping assembly 2, and an adjustment member 3. The frame 1 is fixed relative to the guide rail 100. The clamping assembly 2 is used to clamp the detection assembly 200 and is movably arranged on the frame 1 along a first direction. The end of the adjustment member 3 is connected to the clamping assembly 2, and the adjustment member 3 is screwed to the frame 1. Thus, rotating the adjustment member 3 can drive the clamping assembly 2 to move along the first direction, and further adjust the position of the detection assembly 200 relative to the guide rail 100 in the first direction, so as to adjust the position of the detection assembly 3 relative to the dispensing vehicle, and finally make the position of the in-place detection member 202 of the detection assembly 200 relative to the dispensing vehicle meet the use requirements. In this embodiment, the clamping assembly 2 is used to clamp the fixing member 201 to prevent the in-place detection member 202 from being damaged due to a large clamping force.

[0047] For the adjustment mechanism provided in this embodiment, by fixedly arranging the frame 1 relative to the guide rail 100, an overall support and a reference platform can be provided for the adjustment member 3 and the clamping assembly 2; by connecting one end of the adjustment member 3 to the clamping assembly 2 and screwing the other end to the frame 1, when the adjustment member 3 is rotated, the clamping assembly 2 and the detection assembly 200 clamped by it can be driven to move along the first direction, so as to realize the position adjustment of the detection assembly 200 relative to the guide rail 100 in the first direction; compared with the prior art solution in which workers directly manually adjust the detection assembly, since the adjustment member 3 is threadedly connected to the frame 1, when the worker rotates the adjustment member 3, the moving distance of the adjustment member 3 along the first direction can be known according to the number of turns of the adjustment member 3, so as to realize a relatively accurate position adjustment of the detection assembly 200 in the first direction, and the worker only needs a simple screwing action to realize the position adjustment of the detection assembly 200, with convenient operation, high adjustment efficiency, and reduced workload and labor cost of the worker.

[0048] Specifically, the adjustment member 3 is a bolt with an external thread, and the adjustment member 3 is screwed to the frame 1, so that the adjustment member 3 can be rotated to adjust the relative position of the detection assembly 200 relative to the guide rail 100 in the first direction. In other embodiments, all adjustment members 3 that can drive the clamping assembly 2 to move along the first direction, so as to adjust the relative position of the detection assembly 200 relative to the guide rail 100 in the first direction, are within the protection scope of this application, and the specific types of the adjustment member 3 will not be elaborated one by one.

[0049] Continue as Figures 1 to 2As shown, in order to correct the movement trajectory of the adjustment component 200 when moving in the first direction, the frame 1 has a first slide rail 11 arranged in the first direction. The clamping component 2 is slidably engaged with the first slide rail 11. Thus, when the clamping component 2 clamps the detection component 200 and moves in the first direction, the first slide rail 11 can correct the sliding trajectory of the detection component 200, prevent the detection component 200 from deviating, and at the same time reduce the friction force of the sliding connection of the clamping component 2 relative to the frame 1, so as to facilitate adjusting the position of the detection component 200 in the first direction.

[0050] The clamping component 2 includes a clamping body 21 and a clamping piece 22. The clamping body 21 is connected to the end of the adjusting piece 3 and is slidably arranged on the frame 1. The clamping piece 22 can clamp the detection component 200 and is connected to the clamping body 21. Of course, it can be understood that the clamping piece 22 and the clamping body 21 can be integrally formed to reduce the production cost of the clamping component 2, and the clamping piece 22 and the clamping body 21 can also be detachably connected. When dealing with detection components 200 of different specifications and models, different types of clamping pieces 22 can be replaced according to actual needs, so as to better clamp the detection component 200.

[0051] It is worth noting that it is difficult to firmly clamp the detection component 200 by only setting one clamping piece 22. Therefore, the adjustment mechanism provided in this embodiment can also easily increase the number of clamping pieces 22 according to actual needs, so as to firmly clamp the detection component 200. The number of clamping pieces 22 is multiple, and the multiple clamping pieces 22 are arranged at intervals in the second direction to jointly clamp the detection component 200.

[0052] Continue as Figures 1 to 2 As shown, the clamping component 2 further includes a second slide rail 23. The second slide rail 23 is arranged on the clamping body 21 and extends in the second direction. The clamping piece 22 is slidably engaged with the second slide rail 23, so that the clamping position of the clamping piece 22 clamping the detection component 200 can be adjusted, and thus the detection component 200 can be clamped more firmly.

[0053] Furthermore, the clamping piece 22 includes a first clamping portion 221 and a second clamping portion 222. The first clamping portion 221 and the second clamping portion 222 are oppositely arranged, and the distance between the first clamping portion 221 and the second clamping portion 222 is adjustable. Thus, a clamping space for clamping the detection component 200 is formed between the first clamping portion 221 and the second clamping portion 222, and the width of the clamping space can be adjusted to clamp or release the detection component 200. It is worth noting that the width direction of the clamping space can be the first direction or the second direction, as long as the width of the clamping space can be adjusted to clamp or release the detection component 200, and it is not limited here.

[0054] Further, the clamping member 22 further includes a connecting portion 223. One end of the connecting portion 223 is connected to the second clamping portion 222, and the connecting portion 223 is fixedly connected to the second clamping portion 222. The first clamping portion 221 is adjustably connected to the other end of the connecting portion 223, so that the width of the clamping space can be adjusted for inspection components 200 of different specifications. Specifically, the end of the connecting portion 223 connected to the first clamping portion 221 is provided with an external thread, and the connecting portion 223 is screwed to the first clamping portion 221.

[0055] To more precisely adjust the position of the inspection component 200 relative to the guide rail 100 in the first direction, the adjustment mechanism further includes an adjustment detector 4. The adjustment detector 4 is arranged on the frame 1 and can detect the distance between the adjustment detector 4 and the inspection component 200 in real time. Thus, the initial distance between the inspection component 200 and the adjustment detector 4 can be measured first, and then the preset distance after the position of the inspection component 200 is adjusted can be measured. The difference between the initial distance and the preset distance can obtain the actual moving distance of the inspection component 200 in the first direction. Furthermore, by controlling the actual moving distance of the inspection component 200 in the first direction, the position of the inspection component 200 relative to the dispensing vehicle can meet the usage requirements with only one adjustment. Specifically, the adjustment detector 4 is a laser ranging device. In addition, other detection elements that can detect the distance between the inspection component 200 and itself are within the protection scope of this application and will not be elaborated here one by one.

[0056] In some embodiments, the clamping member body 21 further has a trigger portion 211. The trigger portion 211 is arranged on the clamping member body 21 and faces the adjustment detector 4. The adjustment detector 4 can detect the distance between the trigger portion 211 and itself. The trigger portion 211 can move in the first direction along with the inspection component 200. Thus, when the clamping member 21 clamps inspection components 200 of different specifications, a unified detection reference can be obtained, and thus the actual moving distance of the inspection component 200 in the first direction can be better known. In this embodiment, the top of the clamping member body 21 extends in the width direction of the guide rail 100 to form the above-mentioned trigger portion 211, which has a simple structure and is convenient for processing. Of course, in other embodiments, the trigger portion 211 can also be connected to the clamping member body 21 by means of bolts, buckles, bonding, etc., and this embodiment does not limit this.

[0057] Figure 3 shows a front view structural schematic diagram of the adjustment mechanism provided in this embodiment. As Figures 1 to 3As shown, in this embodiment, the frame 1 is detachably connected to the guide rail 100, so that the adjustment mechanism can be used at any position with the guide rail 100 on the in-place detection device. Specifically, the adjustment mechanism further includes a fastening assembly 5. A receiving groove 12 is also formed on the frame 1. The guide rail 100 is placed in the receiving groove 12, and the fastening assembly 5 fixes the guide rail 100 received in the receiving groove 12 to the frame 1.

[0058] In some embodiments, the fastening assembly 5 includes a fastener 51. The fastener 51 is a bolt with an external thread. The frame 1 has a through hole for the fastener 51 to pass through. The fastener 51 can pass through the through hole and press against the guide rail 100, so as to lock the relative position of the guide rail 100 relative to the frame 1 and lock the relative position of the adjustment mechanism relative to the guide rail 100.

[0059] Furthermore, the fastening assembly 5 further includes a contact pad 52. The contact pad 52 is connected to one end of the fastener 51 and is arranged between the guide rail 100 and the fastener 51, which can increase the friction force of the contact between the fastener 51 and the guide rail 100, thereby improving the stability of the fastening assembly 5 in locking the relative position of the adjustment mechanism relative to the guide rail 100.

[0060] Of course, in other embodiments, the frame 1 can also be fixed to the ground on one side of the guide rail 100, as long as it can keep a relatively fixed position with the guide rail 100.

[0061] This embodiment also provides an adjustment method. The usage steps for the in-place detection device applied to the distribution vehicle to adjust the position of the detection component 200 relative to the guide rail 100 in the first direction are as follows:

[0062] S100. Fix the frame 1 relative to the guide rail 100;

[0063] S200. The clamping assembly 2 clamps the in-place detection piece 202;

[0064] S300. Loosen the locking piece 300 so that the fixing piece 201 can move relative to the guide rail 100 in the first direction;

[0065] S400. Rotate the adjustment piece 3 so that the clamping assembly 2 slides in the first direction, thereby adjusting the position of the detection component 200 relative to the guide rail 100 in the first direction;

[0066] S500. Tighten the locking piece 300 so that the detection component 200 is fixed relative to the guide rail 100.

[0067] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
