Description

Technical Field

[0001] This application relates to the field of suction cup technology, and in particular to a suction cup and its usage method, and an adhesive application device. Background Technology

[0002] With the rapid development of the lithium battery industry, various electronic products such as mobile phones, headphones, and new energy vehicles are increasingly demanding higher quality battery cells. In the battery cell manufacturing process, the adhesive application process is one of the key steps to ensure the packaging quality and appearance consistency of the cells. Adhesive application equipment generally uses suction cup structures to adsorb, transport, and attach the adhesive tape. Therefore, the structural design of the suction cup directly affects the stability, adaptability, and production efficiency of the adhesive application. In existing adhesive application equipment, suction cups are typically designed only for adhesive tapes of a fixed width. When producing different models of battery cells or switching between different widths of process adhesive tape, different widths of adhesive tape require corresponding suction cup structures, necessitating the fabrication of numerous suction cup structures. This significantly increases design, time, and manufacturing costs. Furthermore, each time the suction cup structure is changed, parts must be replaced, making the operation cumbersome.

[0019] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] The following reference Figures 1 to 15 This application describes the suction cups and their usage methods, as well as the adhesive application equipment, in the embodiments of this application.

[0021] according to Figure 1 and Figure 2 As shown, a suction cup according to one embodiment of this application includes a suction component 1 and a cavity adjustment component 2. The suction component 1 is connected to and mounted on the lower side of the cavity adjustment component 2. (Continue to see...) Figure 3 The lower side of the suction component 1 is provided with several suction holes 11. The suction holes 11 penetrate the suction component 1 along the height direction of the suction component 1. The output end of the suction hole 11 can be used to directly contact and adsorb the tape.

[0022] See also Figure 4 and Figure 5The cavity adjustment assembly 2 includes M layers of adjustment assemblies, where M is a natural number greater than 2, meaning the cavity adjustment assembly 2 includes at least two layers of adjustment assemblies. Each layer of adjustment assembly is provided with a cavity 21. The cavity 21 of the Nth layer of adjustment assembly is fitted from top to bottom onto the outside of the cavity 21 of the (N+1)th layer of adjustment assembly, where N is a natural number between 1 and M, forming a tower-like structure that expands layer by layer from the inside out. For example, the cavity 21 of the first layer of adjustment assembly 3 is located on the outermost side. The cavity 21 of the first layer of adjustment assembly 3 is fitted from top to bottom onto the outside of the cavity 21 of the second layer of adjustment assembly 4. The cavity 21 of the second layer of adjustment assembly 4 is fitted from top to bottom onto the outside of the cavity 21 of the third layer of adjustment assembly 5, and so on, until the Mth layer of adjustment assembly. The output end of the cavity 21 of each layer of the adjustment component is connected to the input end of the suction hole 11 in the corresponding region of the suction component 1. Due to the tower structure, the output ends of the cavities 21 of different adjustment components are at different radial positions, and the adsorption width expands in a stepped manner. When negative pressure is introduced into any layer of cavity 21, the negative pressure will act on the suction hole 11 of the corresponding region through that layer of cavity 21, causing that region to generate adsorption capacity. See also Figure 6 Each layer of adjustment component has a corresponding connection hole at the input end of the cavity 21. The connection hole is used to connect an external vacuum generator to generate negative pressure on the corresponding adjustment component.

[0023] In use, select the corresponding adjustment component based on the width of the tape, and open the connection hole of that adjustment component to create negative pressure within the cavity 21 of that layer. This negative pressure acts on the tape surface through the corresponding suction hole 11, thereby achieving adsorption. Since the cavities 21 of each layer are fitted at different radial positions, the adsorption coverage width corresponding to each layer adjustment component is different. The adjustment component located in the inner layer has a narrower adsorption range, suitable for narrower tapes; the adjustment component located in the outer layer has a larger adsorption range, suitable for wider tapes. The outermost layer has a wider adsorption width. By controlling the opening and closing of the connection holes of different layer adjustment components, the generation of negative pressure in the corresponding cavity 21 can be controlled, thus forming adsorption ranges of different widths. This allows for adjustable adsorption areas and enables the suction cup to adsorb tapes of different widths.

[0024] This application provides a novel, compact suction cup. By setting a multi-layered, nested cavity structure 21, the suction cup can selectively open different cavity layers 21 according to the tape width, thereby achieving adjustable adsorption area. This effectively solves the problem that traditional suction cups need to be replaced for different tape widths. There is no need to replace the suction cup body; only the opening and closing of the connection holes of different adjustment components needs to be controlled to adjust the suction cup adsorption width. This greatly reduces the workload of changeover, improves the versatility and changeover efficiency of the device, and also reduces manufacturing costs and maintenance burden.

[0025] In some embodiments, see Figure 1 and Figure 6The upper side of the cavity adjustment assembly 2 is provided with a fixing hole 22 for connecting the adhesive application equipment.

[0026] according to Figure 4 and Figure 5 As shown, in one embodiment of this application, the cavity 21 includes an upper cavity, a left cavity, and a right cavity. The upper cavity extends along the width direction of the cavity adjustment assembly 2, and its two ends are respectively connected to the input ends of the left cavity and the right cavity. (Continuing to the previous section...) Figures 9 to 15 The output ends of the left and right cavities are located on the two sides of the lower side of the cavity adjustment assembly 2, and are connected to the suction holes 11 in the corresponding areas, so that the negative pressure can simultaneously adsorb the two sides of the upper surface of the tape from both sides, ensuring a stable and reliable adsorption effect on the tape in the application of adhesive.

[0027] In some embodiments, sealing plates 10 are provided at the cavities 21 on both the front and rear sides of the suction cup.

[0028] according to Figures 9 to 15 As shown, in one embodiment of this application, the upper cavities of each layer of adjustment components are arranged parallel to each other, and the widths of the upper cavities of the first layer of adjustment component 3 to the Mth layer of adjustment component decrease sequentially. The left cavities of each layer of adjustment components are arranged parallel to each other, and the right cavities of each layer of adjustment components are arranged parallel to each other. The heights of the left cavities of the first layer of adjustment component 3 to the left cavities of the Mth layer of adjustment component decrease sequentially, and the heights of the right cavities of the first layer of adjustment component 3 to the right cavities of the Mth layer of adjustment component decrease sequentially.

[0029] In some embodiments, in each layer adjustment component, the left cavity is perpendicular to the upper cavity, and the upper cavity is perpendicular to the right cavity, so that the cavity 21 composed of the left cavity, upper cavity, and right cavity has a dome shape. In other embodiments, the cavity 21 can be configured as an arc shape, bow shape, etc.

[0030] according to Figures 6 to 8 As shown, in one embodiment of this application, the length of the upper cavity of the N+2 layer adjustment component along the length direction of the suction cup is greater than the length of the upper cavity of the Nth layer adjustment component.

[0031] according to Figure 3 As shown, in one embodiment of this application, the suction holes 11 are arranged in an array. The array of suction holes 11 covers the entire lower side of the suction assembly 1, and the density of the suction holes 11 in different areas is consistent, so that the adsorption capacity of the suction cup is uniformly distributed in a planar shape.

[0032] In one embodiment of this application, the attraction component 1 is made of urethane, which has good elastic deformation ability and can withstand the friction of the tape during repeated adsorption actions, ensuring that the tape does not slip off and does not scratch the tape.

[0033] according to Figures 1 to 15As shown, one embodiment of this application describes a method of using the suction cup described above, the method of which includes: The connection holes of the vacuum generator connection cavity adjustment assembly 2; Depending on the required width of the adhesive tape, selectively open the connection holes of the corresponding layer adjustment component to activate the corresponding layer adjustment component; When the width of the tape is greater than the first preset width, the first layer adjustment component 3 is activated, so that the cavity 21 of the first layer adjustment component 3 generates negative pressure and forms a corresponding adsorption area; at this time, the suction cup only activates the first layer, and the adsorption range is suitable for narrower tapes.

[0034] When the tape width is greater than the Nth preset width and less than the (N-1)th preset width, where N is a natural number greater than 2, the Nth layer adjustment component is activated.

[0035] according to Figures 1 to 15 As shown, in one embodiment of this application, the Nth layer adjustment component and the Lth layer adjustment component are selectively activated according to the width and weight of the tape, where L is a natural number greater than N and less than or equal to M.

[0036] When the width and weight of the tape are greater than the first preset width and the first preset weight, the first layer adjustment component 3 is activated, and at least one of the second layer adjustment component 4, the third layer adjustment component 5, or the Lth layer adjustment component is selectively activated to enhance the suction.

[0037] When the tape width is greater than the Nth preset width and less than the N-1th preset width, and the weight is greater than the Nth preset weight, where N is a natural number greater than 2, the Nth layer adjustment component is activated, and at least one of the N+1th layer adjustment component, the N+2th layer adjustment component, or the Lth layer adjustment component is selectively activated again.

[0038] This application, through the above-described method of using the suction cup, can simultaneously consider the width and weight of the tape, enabling the suction cup to match the appropriate adsorption level according to the actual situation of the tape, thereby improving adsorption stability and avoiding insufficient adsorption or even detachment.

[0039] according to Figures 1 to 15 As shown, an embodiment of the adhesive applicator of this application includes the suction cup described in the above embodiment. The adhesive applicator also includes a vacuum generator, which is connected to each connection hole of the suction cup.

[0040] The suction cup, its usage method, and adhesive application structure of this application firstly utilize a multi-layered, nested adjustment assembly inside the suction cup. Different levels of cavities 21 can be connected to an external vacuum generator, thereby enabling controllable activation of the adsorption area. Each cavity 21 consists of an upper cavity, a left cavity, and a right cavity, which are nested sequentially in a tower-like structure, resulting in a progressively increasing width and height distribution from the inside out for each cavity 21. Combined with the array of suction holes 11 on the suction assembly 1, the effective adsorption width of the suction cup can be precisely adjusted in layers by selecting and opening the corresponding level of cavities 21 to meet different tape width application requirements. Furthermore, by opening different combinations of layered cavities 21, differences in tape width and weight can be simultaneously considered, ensuring stable negative pressure distribution and uniform adsorption force during adsorption.

[0041] In the adhesive application equipment, the vacuum generator is reliably connected to each layer of the suction cup's cavities 21, allowing each cavity 21 to be opened and closed independently under the equipment control system, thus forming a negative pressure adsorption system with dynamically switchable adsorption width. Through the novel suction cup structure, this application achieves adaptation to various tape widths and weights without replacing the suction cup hardware, significantly reducing debugging time during production line changeovers and lowering the number of spare parts and manufacturing costs. Simultaneously, the multi-layer parallel cavity structure 21, combined with the arrayed adsorption holes, makes the negative pressure adsorption more uniform, improving the stability and consistency of the adhesive application process.

[0042] according to Figures 1 to 15 As shown, the following is one embodiment of this application: See Figure 1 , Figure 4 and Figure 5 The cavity adjustment assembly 2 includes seven layers of adjustment assemblies, including a first layer adjustment assembly 3, a second layer adjustment assembly 4, a third layer adjustment assembly 5, a fourth layer adjustment assembly 6, a fifth layer adjustment assembly 7, a sixth layer adjustment assembly 8, and a seventh layer adjustment assembly 9.
