DETAILED DESCRIPTION

[0045] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0046] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0047] As described in the background technology, the current clamp is two relatively movable end plates that clamp the two ends of the wine box and then flip the wine box. This clamping method firstly puts pressure on the wine box and makes it easy to deform. Secondly, the clamping force is difficult to control. If it is too large, the wine box may easily deform, and if it is too small, it may cause the wine box to detach from the clamp during processing.

[0048] Embodiment 1:

[0049] Therefore, in order to solve the above technical problems of the prior art, the present embodiment proposes a clamping mechanism 300, which is provided with at least one group, wherein at least one group of the clamping mechanism includes a plurality of clamping box parts, and the plurality of the clamping box parts are linearly and equidistantly arranged, and the clamping box parts are extended into the interior of the packaging box and act outwardly on the two opposite inner side walls of the packaging box to fix the packaging box;

[0050] The cartridge portion comprises:

[0051] Power plant;

[0052] The clamping jaw drives the clamping jaw to move linearly through a power device so that the clamping jaw can loosen or tighten the packaging box.

[0053] The packaging box clamp can be installed on a mechanical arm or a lifting device. The clamping box part is sent into the packaging box by the mechanical arm or the lifting device. The power device of the clamping box part drives the clamping claws to move outward to squeeze the inner wall of the packaging box outward, thereby fixing the packaging box. The packaging box is not easy to deform or fall off during the clamping and fixing process.

[0054] In this embodiment, the clamping claw may be a plate-shaped structure made of anti-slip material.

[0055] An anti-slip sleeve 353 may be sleeved on the outside of the clamping jaw.

[0056] The clamping jaws are made of anti-skid material and are covered with anti-skid sleeves on their outer sides to increase the friction between the clamping jaws and the paper box to prevent the paper box from falling during transportation.

[0057] It should be noted that the anti-slip sleeve and the clamping claws can be made of materials such as silicone, rubber, etc. that can prevent the packaging box from slipping.

[0058] In this embodiment, the clamping mechanism may further include a mounting plate 310, and the above-mentioned clamping box parts may be fixedly mounted on the mounting plate.

[0059] Embodiment 2:

[0060] This embodiment provides a solution for the cartridge part, such as Figure 1 , 2 As shown, the cartridge section selects the first cartridge section 320, such as Figure 3 , 4 As shown, the first cartridge portion comprises:

[0061] Ordinary cylinder 321;

[0062] The first clamping jaws 322 are provided with two groups, and the two groups of the first clamping jaws are driven to move linearly by a common cylinder 321, and the movement directions of the two groups of the first clamping jaws are opposite.

[0063] In this embodiment, the above-mentioned common cylinder can be a finger cylinder, a rodless cylinder, etc., and the above-mentioned first clamping jaw is installed on the common cylinder, and the first clamping jaw is driven to move linearly by the common cylinder.

[0064] When the mechanical arm or the lifting device sends the clamping part into the packaging box, the common cylinder drives the first clamping claw to move outward to press the inner wall of the packaging box outward, thereby fixing the packaging box.

[0065] Embodiment 3:

[0066] Since the cost of ordinary cylinders is relatively high and they occupy a large space, this embodiment provides another solution for the clamping box part, such as Figure 5 As shown, the cartridge section selects the second cartridge section 350, such as Figure 6 As shown, the second cartridge portion comprises:

[0067] Compact cylinder 352;

[0068] The second clamping jaws 351 are provided with two groups, and the two groups of the second clamping jaws are driven by the compact cylinder 352 to move linearly, and the movement directions of the two groups of the second clamping jaws are opposite.

[0069] In this embodiment, the compact cylinder can be a compact double-headed cylinder, and the second clamping jaw is connected to the piston rod of the double-headed cylinder.

[0070] By using compact cylinders, the economical production of clamps can be improved.

[0071] Since a compact cylinder with a small space is used, the clamp in this embodiment has installation space for installing other structures. For example, the second clamping jaw can use two hard chrome-plated optical shafts as guides, and a fixed ring is used as a limit in the middle position of the guide optical shaft. That is, the guide optical shaft is set along the movement direction of the second clamping jaw, and the second clamping jaw is kept in sliding connection with the guide optical shaft through a linear bearing. When the second clamping jaw moves, its movement is guided by the guide optical shaft to improve the movement accuracy of the clamping jaw. A fixed ring is installed on the guide optical shaft section between the clamping jaws to limit the formation of the clamping jaws.

[0072] When the robotic arm or lifting device sends the clamping part into the packaging box, the compact cylinder will drive the clamping claws to move outward to squeeze the inner wall of the packaging box outward, thereby fixing the packaging box. The packaging box is not easy to deform or fall during the clamping process.

[0073] In this embodiment, a packaging box limiting block 360 may be further provided on the outer side of the second clamping jaw, and the shape of one side of the packaging box limiting block 360 close to the second clamping jaw matches the shape of the outer side of the packaging box.

[0074] The position of the packaging box is limited by the packaging box limit block matched with the outer side of the packaging box, so as to realize the accurate positioning of the packaging box and facilitate the gripping of the clamping claw. At the same time, the limit block cooperates with the clamping claw of the clamping box part to clamp and fix the side wall of the packaging box, which can effectively avoid the deformation of the packaging box when the clamping claw exerts too much pressure on the inner wall.

[0075] In this embodiment, if Figure 5As shown, the clamping mechanism 300 may also include a limit block mounting plate 340, which is arranged parallel to the mounting plate and fixedly installed below the mounting plate. A limit groove is provided on the limit block mounting plate corresponding to the clamping box part for the above-mentioned second clamping claw to extend to the bottom of the limit block mounting plate, and the above-mentioned packaging box limit blocks are arranged on both sides of the limit groove.

[0078] Connecting plate 110;

[0079] The buffer plate 130 is arranged parallel to the above-mentioned connecting plate 110. The buffer plate is connected to the connecting plate 110 through a guide shaft. The buffer plate 130 can move relative to the connecting plate along the axial direction of the guide shaft. An elastic member is provided between the above-mentioned connecting plate and the buffer plate, and the above-mentioned clamping mechanism is installed on the buffer plate.

[0080] By using a buffer mechanism to buffer the clamping operation of the clamp, it can not only ensure that the product with manufacturing tolerances in the outer dimensions can be grasped, but also avoid the entire clamp being rigid at the moment of grasping the product.

[0081] In this embodiment, the elastic member may be a spring, and the spring may be sleeved on the guide shaft.

[0082] Embodiment 5:

[0083] In order to realize the clamping of multiple columns or rows of packaging boxes, such as Figure 1 , 2 As shown in 5, the clamping mechanism is provided with multiple groups;

[0084] The clamp further comprises a transfer mechanism 200 , which is mounted on the buffer plate and drives the array of clamping mechanisms to move linearly.

[0085] like Figure 8 As shown, the transplanting mechanism includes a third power device 210;

[0086] In this embodiment, the mounting plate is slidably connected to the buffer plate, and the mounting plate is driven to move linearly by the third power device.

[0087] In this embodiment, the above-mentioned mounting plate can be connected to the buffer plate by a translation slide rail 220 to limit the freedom of movement of the entire clamping mechanism.

[0088] In addition, if Fig. 9 As shown, the transplanting mechanism also includes

[0089] A stop block 240, wherein the stop block 240 is fixedly mounted on the mounting plate;

[0090] The stopper 230 is arranged corresponding to two sides of the stop block and is fixedly mounted on the buffer plate.

[0091] The clamping mechanism is driven by the transfer mechanism to move to the positioning position of the product. After the product is clamped, the spacing between the columns or rows of products can be changed by the transfer mechanism.

[0092] In an embodiment, the above-mentioned stopper may be an oil pressure buffer.

[0093] In addition, the clamping mechanism is equipped with a non-standard air distributor, which cleverly drives multiple groups of clamping box parts to achieve the action of grabbing the product.
