Adaptive clamping device for material boxes

Abstract

This utility model discloses an adaptive clamping device for material boxes, including a mounting base, a clamping base, and a drive assembly. When clamping a material box, simply place the box on the support platform, then start the motor to drive the clamping base downwards, gradually approaching the box. During the downward movement of the clamping base, the positioning arm on the clamping arm assembly first contacts the top of the box, then moves relative to the clamping arm. Once the positioning detection element detects the positioning element, the motor stops, completing the clamping of the box. This clamping device is suitable for clamping boxes of different heights. When the height of the box changes, there is no need to replace the clamping base according to the actual height of the box, nor is there a need to adaptively adjust the control program. This avoids reduced production efficiency and wasted labor due to downtime for changing the clamping base, as well as increased costs and wasted resources caused by using different clamping bases.

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] In this document, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings when the clamping device is used to clamp the material box in the vertical direction. They are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Figures 1 to 8 The diagrams are drawn to scale. To keep the instructions concise, the proportions of each component are not listed individually. However, the proportions and positions of each component should be considered part of the contents of this instruction manual.

[0037] See Figures 1 to 8 The diagram illustrates an adaptive clamping device for holding a material box 10, facilitating its transport to a desired location. The clamping device includes:

[0038] Mounting base 1, which has a support platform 12 for supporting material box 10;

[0039] The clamping seat 2 is vertically movable on the mounting seat 1. The clamping seat 2 is provided with a clamping arm assembly, which cooperates with the mounting seat 1 in the vertical direction to form a clamping space for clamping the material box 10.

[0040] The drive assembly 3 includes a lead screw 31 that extends in the vertical direction and is rotatable about its own axis and is mounted on the mounting base 1, and a motor 32 for driving the lead screw 31 to rotate. The clamping base 2 is threadedly connected to the lead screw 31 and is able to move linearly along the length of the lead screw 31.

[0041] In this clamping device, the clamping arm assembly includes a clamping arm 22 fixedly disposed on the clamping base 2, and a positioning arm 23 that can float on the clamping arm 22 in the vertical direction. The positioning arm 23 is provided with a positioning element 25, and the clamping base 2 is provided with a positioning detection element 26 for detecting the positioning element 25. The positioning detection element 26 is connected to the motor 32 via a signal.

[0042] Thus, during the process of the motor 32 driving the lead screw 31 to rotate, thereby driving the clamping seat 2 to move downward to clamp the material box 10, the positioning arm 23 first contacts the top of the material box 10. As the clamping seat 2 continues to move downward, the positioning arm 23 is squeezed by the material box 10 and moves upward relative to the clamping arm 22. The positioning element 25 moves upward and approaches the positioning detection element 26. When the positioning detection element 26 detects the presence of the positioning element 25, the positioning detection element 26 sends a trigger signal to the motor 32, the motor 32 stops working, and the clamping seat 2 stops moving downward. At this time, the clamping seat 2 and the support table 12 cooperate to form a fixed clamping of the material box 10.

[0043] Thus, when clamping the material box 10, simply place the material box 10 on the support platform 12, then start the motor 32. The motor 32 drives the lead screw 31 to rotate, causing the clamping seat 2 to move downwards and gradually approach the material box 10. During the downward movement of the clamping seat 2, the positioning arm 23 on the clamping arm assembly first contacts the top of the material box 10. Then, the clamping seat 2 moves downwards, and the positioning arm 23 moves relative to the clamping arm 22. After the positioning detection element 26 detects the positioning element 25, it controls the motor 32 to stop working, thus completing the clamping of the material box 10. This clamping device can be used to clamp material boxes 10 of different heights. When the height of the material box 10 changes, it is not necessary to replace the clamping seat 2 according to the actual height of the material box 10, nor is it necessary to adaptively adjust the control program. This avoids the reduction in production efficiency and waste of labor caused by stopping the machine to replace the clamping seat 2, as well as the increased cost and waste of resources caused by using different clamping seats.

[0044] Specifically, referring to the accompanying drawings, in this embodiment, the clamping seat 2 includes a nut seat 21 threadedly engaged with the lead screw 31. The clamping arm 22 has a first end 221 and a second end 222 located at opposite ends along its length. The first end 221 is fixedly mounted on the nut seat 21. The positioning arm 23 has a rotating end 231 and a swinging end 232 located at opposite ends along its length. The rotating end 231 is rotatably connected to the second end 222. An elastic element 24 is also provided between the swinging end 232 and the clamping arm 22. Here, the elastic element 24 is specifically a spring, which is stretched and extended in the vertical direction between the first end 221 and the swinging end 232. During the downward movement of the clamping seat 2, the swinging end 232 first contacts the upper part of the material box 10, and then is squeezed and overcomes the spring force to move towards the clamping arm 22 until the positioning member 25 and the positioning detection element 26 cooperate with each other, and the clamping seat 2 stops moving downward. In a specific configuration, a limiting flange 211 is also provided on the nut seat 21. The limiting flange 211 is located below the clamping arm 22 to limit the downward swing of the swing end 232, thereby ensuring that the elastic element 4 is stably installed between the clamping arm 22 and the positioning arm 23.

[0045] See Figure 1As shown, the positioning detection element 26 has a positioning groove 261. The positioning member 25 can be inserted into or detached from the positioning groove 261 in the vertical direction. When the positioning member 25 is inserted into the positioning groove 261, the positioning detection element 26 is connected to the motor 32, thereby controlling the motor 32 to stop working, so that the clamping seat 2 stops at the current position. Here, the positioning member 25 is fixedly set on the swing end 232 of the positioning arm 23. The positioning groove 261 is a U-shaped groove with its opening facing the rotating end 231. When the positioning arm 23 swings relative to the clamping arm 22, the positioning member 25 swings upward and inserts into the positioning groove 261, thereby triggering the motor 32 to stop working and causing the clamping seat 2 to stop lifting and lowering.

[0046] The clamping arm assembly on the clamping base 2 has multiple sets of clamping arms arranged at intervals. The length extension directions of all clamping arms 22 are parallel to each other and located at the same height. All clamping arm assemblies cooperate to clamp the material box 10 from above. Here, there are two sets of clamping arm assemblies, and the two sets of clamping arm assemblies are located on opposite sides of the lead screw 31. The positioning detection element 26 is specifically set on the clamping arm 22 of one set of clamping arm assemblies.

[0047] Referring to the accompanying drawings, the mounting base 1 also includes a main body 11 and a mounting platform 13. The mounting platform 13 is located on top of the main body 11, and the mounting platform 13 and the support platform 12 are located on the same side of the main body 11. The motor 32 is located on top of the mounting platform 13. The clamping seat 2 moves vertically between the mounting platform 13 and the support platform 12. Multiple columns 4 are connected between the support platform 12 and the mounting platform 13. The clamping seat 2 is slidably mounted on the columns 4. During the vertical movement of the clamping seat 2, the columns 4 provide stable guidance for the clamping seat 2.

[0048] A positioning structure is provided on the support platform 12. This positioning structure is configured to cooperate with the bottom of the material box 10 so that the material box 10 is fixedly supported on the support platform 12. Specifically, in this embodiment, the support platform 12 includes a platform body 121 and a connecting seat 122. The platform body 121 and the main seat body 11 are integrally formed, and the connecting seat 122 is detachably connected to the platform body 121. The positioning structure is provided on the platform body 121. Here, the positioning structure includes a support surface 12a extending in the horizontal direction, a limiting surface 12b located on one side of the support surface 12a and extending in the vertical direction, and a groove 12c recessed downward from the support surface 12a. The material box 10 is supported on the support surface 12a, one side of the material box 10 abuts against the limiting surface 12b, and at least part of the bottom of the material box 10 is inserted into the groove 12c.

[0049] The support platform 12 is also equipped with a positioning sensor 6, which is connected to the motor 32. When the material box 10 is correctly supported on the support platform 12, that is, when the material box 10 is supported on the support surface 12a and one side of it abuts against the limiting surface 12b, the positioning sensor 6 can send a positioning signal. Then, after receiving the signal, the motor 32 starts to run, causing the clamping seat 2 to move downward to clamp the material box 10.

[0050] In this embodiment, a positioning sensor 5 is also provided between the mounting platform 13 and the clamping seat 2. The positioning sensor 5 is configured to send a positioning signal when the distance between the clamping seat 2 and the mounting seat 1 reaches a preset value. The positioning sensor 5 is signal-connected to the motor 32. After receiving the positioning signal, the motor 32 stops running to prevent the clamping seat 2 from moving upward and overshooting, which could damage the device.

[0051] In summary, when using the clamping device of this embodiment to clamp the material box 10, the material box 10 is first placed on the support platform 12. After the positioning sensor 6 detects that the material box 10 is correctly placed, it sends a signal to the motor 32. The motor 32 works and drives the lead screw 31 to rotate, causing the clamping seat 2 to move downward as a whole. During the downward movement of the clamping seat 2, the swing end 232 of the positioning arm 23 first contacts the top of the material box 10. As the clamping seat 2 continues to move downward, the elastic element 4 is squeezed, and the positioning element 25 gradually enters the positioning groove 261 of the positioning detection element 26. The positioning detection element 26 sends a signal to trigger the motor 32 to stop running, the clamping seat 2 is fixed in the current position, and the material box 10 is clamped between the clamping arm assembly and the support platform 12. This clamping device is suitable for clamping material boxes 10 of different sizes. When the size of the material box 10 changes, it can automatically adjust the lifting position of the clamping seat 2 to ensure stable clamping of the material box 10 without stopping the machine to replace the parts of the clamping device, thereby improving the overall production efficiency and reducing the equipment cost.
