Description

Technical Field

In the drawings, the thickness of regions and layers are exaggerated for clarity. The same reference numerals in the drawings represent the same or similar structures, and thus their detailed description will be omitted.

[0027] The described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solution of the present invention may be practiced without one or more of the specific details, or other methods, components, materials, etc. may be used. In other cases, known structures, materials or operations are not shown or described in detail to avoid blurring the various aspects of the present invention.

[0028] The following example is a conveyor mechanism of the utility model. This example is only a part of the embodiment of the utility model, but the protection scope of the utility model is not limited to this. All other embodiments obtained by ordinary technicians in this field without creative work should be included in the protection scope of the utility model.

[0029] Please refer to Figures 1 to 8 According to an embodiment of the utility model, a conveying mechanism is provided, including a negative pressure adsorption component (not labeled in the figure) and a connecting component (not labeled in the figure), the negative pressure adsorption component includes a material taking plate 11 and an assembly plate 12 which are stacked and assembled up and down, wherein the material taking plate 11 is used to adsorb adhesive tape and / or welding tape (it can be understood that when adsorbing adhesive tape and welding tape at the same time, in a specific embodiment, the adhesive tape and welding tape are prefabricated into a composite part), the connecting component includes a thin sheet connecting plate 21 and a connecting head 22 fixedly connected (preferably threadedly connected) to the thin sheet connecting plate 21, the connecting head 22 is used to connect with a displacement driving member (for example, a handling device capable of self-control movement such as a robotic arm, not shown in the figure), the thin sheet connecting plate 21 is fixedly connected to the first side surface (that is, Figure 1 The thin sheet connecting plate 21 is on the top side surface in the orientation shown, and there is an elastic deformation spacing (not marked in the figure) between the thin sheet connecting plate 21 and the first side surface. The specific thickness of the thin sheet connecting plate 21 can be reasonably selected according to its material and load, so as to meet the deformation amount of the thin sheet connecting plate 21 to prevent excessive rigid collision between the material picking plate 11 and the material receiving plate 200 and the smooth movement of the conveying mechanism by the robot arm, which can be specifically determined through experiments.

[0030] In this technical solution, a thin film connecting plate 21 is provided on one side of the adsorption component. When the corresponding conveying device controls the conveying mechanism to take the corresponding belt body (adhesive tape and / or welding tape) from the receiving plate 200, when the adsorption surface of the material taking plate 11 contacts the bearing surface of the material receiving plate 200, the thin film connecting plate 21 can adaptively adapt the bearing surface to a corresponding degree of deformation (its own elastic deformation), thereby avoiding collision and collapse that may be caused by the conflict between the upper and lower rigid plates, and is conducive to the reliable and stable adsorption of the belt body by the material taking plate 11.

[0031] In some embodiments, the thin-sheet connecting plate 21 includes two side beam sections 211 that are parallel and spaced apart from each other and an intermediate connecting section 212 located between the two side beam sections. The two side beam sections 211 and the intermediate connecting section 212 form an I-shape. The two ends of each side beam section 211 are fixedly connected to the first side surface of the assembly plate 12 through a support column 213, and the connecting head 22 is fixedly arranged in the middle length area of ​​the intermediate connecting section 212.

[0032] In this technical solution, the I-shaped thin-sheet connecting plate 21 is fixedly connected to the assembly plate 12 through support columns 213 at the four corner areas, and the connecting head 22 connected to the handling device is arranged in the central area of ​​the thin-sheet connecting plate 21, which can ensure the uniformity of the deformation of the thin-sheet connecting plate 21 and facilitate the control and adjustment of its deformation.

[0033] In a preferred embodiment, a deformation limiting mechanism is also connected to the first side surface, which is used to limit the deformation of the thin-film connecting plate 21 in a direction away from or close to the first side surface. The deformation limiting mechanism can limit the maximum deformation of the thin-film connecting plate 21 to prevent damage caused by excessive twisting of the thin-film connecting plate 21.

[0034] See Figure 1 As shown, in a specific embodiment, the deformation limiting mechanism includes a first limiting pin 31 and a second limiting pin 32, wherein the first end (bottom end) of the first limiting pin 31 is fixedly connected to the assembly plate 12 (for example, threaded connection), and the second end (top end) of the first limiting pin 31 passes through the connecting head 22 and is located on the side of the connecting head 22 away from the assembly plate 12 (that is, the top side) to form a limit for the deformation of the thin-film connecting plate 21 away from the assembly plate 12. In a specific embodiment, the second end of the first limiting pin 31 forms an outer flange, the first end (bottom end) of the second limiting pin 32 is fixedly connected to the assembly plate 12, and the second end (top end) of the second limiting pin 32 is located on the side of the connecting head 22 close to the assembly plate 12 to form a limit for the deformation of the thin-film connecting plate 21 close to the assembly plate 12.

[0035] In this technical solution, the maximum upward or downward deformation of the thin-sheet connecting plate 21 is limited by the first limiting pin 31 and the second limiting pin 32 respectively, and both are threadedly connected to the assembly plate 12, so the structure is simple and easy to use.

[0036] In some embodiments, the end surface of the pick-up plate 11 away from the assembly plate 12 is provided with a plurality of adsorption air nozzles 111 and a connecting strip 4. It can be understood that the adsorption air nozzles 111 are arranged in a horizontal and vertical array to satisfy the adsorption of the strip body with a horizontal letter interval at the same time. The connecting strip 4 has a plurality of spring probes 41, and each of the spring probes 41 is located on both sides of each of the adsorption air nozzles 111 corresponding to the position so as to form a pressure holding on both sides of the width of the strip body adsorbed by the adsorption air nozzle 111. When the spring probes 41 are in a free state, the pressing surface of each of the spring probes 41 protrudes from the adsorption surface of the adsorption air nozzle 111. Specifically, two adjacent spring probes 41 form a group, which are used to press on both sides of the width of the strip body. They are used to prevent the tape from adhering to the side of the adsorption air nozzle 111 and lifting the tape after the tape body (such as tape) is transported to the battery cell, and finally separate from the tape after the adsorption air nozzle 111 is separated from the tape. In some embodiments, at least two connecting strips 4 are provided, and the two connecting strips 4 are spaced apart along the length extension direction of the belt body.

[0037] See Figure 5 As shown, a groove 113 capable of accommodating the soldering tape is formed in the central area of ​​the soldering surface of each of the suction air nozzles 111, so as to ensure reliable suction and transportation of the soldering tape and the composite member formed by the soldering tape and the adhesive tape.

[0038] In some embodiments, a negative pressure chamber 100 is formed between the feeding plate 11 and the assembly plate 12, which is specifically connected to an external negative pressure generating device via an air pipe 101, and each of the adsorption air nozzles 111 is connected to the negative pressure chamber 100 via each of the air holes 112 constructed on the feeding plate 11, and a baffle 13 is provided in the negative pressure chamber 100, and the baffle 13 has a belt placement position that simultaneously blocks each of the air holes 112 and a belt adsorption position that simultaneously passes through each of the air holes 112, and the baffle 13 can be driven to switch between the belt placement position and the belt adsorption position.

[0039] In this technical solution, when the baffle 13 is in the belt body adsorption position, each air hole 112 is connected with the negative pressure chamber 100, so as to achieve the purpose of negative pressure adsorption on the adsorption surface of each adsorption air nozzle 111, and when the baffle 13 is in the belt body placement position, each air hole 112 is disconnected from the negative pressure chamber 100, and each adsorption air nozzle 111 loses negative pressure, so that the material removal plate 11 can smoothly place the belt body on the surface of the battery cell, ensuring the reliable adhesion of the tape and the battery cell.

[0040] See Figure 4 As shown, a fixing plate 14 is further provided in the negative pressure chamber 100, and the fixing plate 14 is fixedly connected to the feeding plate 11 to define a sliding gap between the two to form the shielding plate 13, and the shielding plate 13 can be driven to slide back and forth in the sliding gap to realize the switching of the shielding plate 13 between the belt placement position and the belt adsorption position, and the fixing plate 14 is fixedly connected to the top side of the feeding plate 11. In a specific embodiment, a plurality of rows of first flow holes 13 arranged along a line of spacing are provided on the shielding plate 13. 2. A plurality of rows of second through-holes 142 are arranged along a line of intervals on the fixed plate 14. The first through-holes 132 and the second through-holes 142 pass through the upper and lower parts of the shielding plate 13 and the fixed plate 14, respectively. It can be understood that when the shielding plate 13 is in the belt placement position, the first through-holes 132 and the second through-holes 142 are offset from each other to form a blockage for each air hole 112. When the shielding plate 13 is in the belt adsorption position, the first through-holes 132 and the second through-holes 142 are connected one by one and are connected one by one with each air hole 112.

[0041] In this technical solution, the position switching of the shielding plate 13 is achieved in a sliding manner, and the structure is simple and compact.

[0042] See Figure 2 As shown, in some embodiments, pneumatic push rods 5 are respectively provided on both sides of the sliding direction of the baffle 13, and the pneumatic push rods 5 on both sides can be controlled to operate alternately. Specifically, on the opposite sides of the baffle 13, two pneumatic push rods 5 are respectively provided on each side, so as to form a balanced force on the two ends of the same side of the baffle 13, thereby ensuring the smooth switching of the position of the baffle 13.

[0043] For specific combination, see Figure 4 and Figure 8 In a preferred embodiment, the shield plate 13 has a long sliding limit hole 131, and the fixed plate 14 is fixedly provided with a sliding limit pin 141, and the sliding limit pin 141 is inserted into the long sliding limit hole 131, so as to realize precise control and adjustment of the position switching of the shield plate 13.

[0044] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations.
