Description

Technical Field

[0001] This application relates to the field of automated production technology, and in particular to an adsorption mechanism and testing device. Background Technology

[0002] In the current manufacturing process of 3C consumer electronics products, manual labor cannot keep up with the production pace due to the large volume of work, necessitating the assistance of automated equipment. For example, in the assembly and testing processes, automated adsorption devices are often used to hold products in place or move them.

[0003] Currently, during the adsorption process of products by adsorption devices, the adsorption force is often too small to stably adsorb the products, resulting in the products easily loosening or even adsorption failure. Utility Model Content

[0004] Therefore, it is necessary to provide an adsorption mechanism and testing device to address the problem that existing adsorption devices cannot stably adsorb products.

[0005] An adsorption mechanism, the adsorption mechanism comprising:

[0006] Fixing plate; and

[0007] An adsorption plate is movably disposed on the fixed plate for adsorbing products. The adsorption plate has at least one adsorption air channel, which is annular and extends along the circumferential direction of the adsorption plate.

[0008] In one embodiment, there are multiple adsorption channels, which are spaced apart on the adsorption plate and extend in the same direction.

[0009] In one embodiment, the adsorption mechanism further includes a support plate disposed on the side of the adsorption plate away from the fixed plate, for supporting the product, and the support plate is provided with an annular air outlet corresponding to the adsorption air channel, the air outlet being connected to the adsorption air channel.

[0010] In one embodiment, the air outlet includes a plurality of air intake holes, which are spaced apart along the circumferential direction of the support plate, and all of the plurality of air intake holes are connected to the adsorption air channel.

[0011] In one embodiment, the adsorption airway includes a flow channel, a first air intake port and a second air intake port, both of which are connected to the flow channel. The first air intake port is located inside the flow channel, and the second air intake port is connected to an air intake element.

[0012] In one embodiment, the adsorption mechanism further includes an adjustment component connected to the fixed plate and the adsorption plate, for adjusting the gap between the fixed plate and the adsorption plate.

[0013] In one embodiment, the adjustment assembly includes a connector and an adjustment screw. The connector is movably connected to the adsorption plate and the fixed plate. The adjustment screw is disposed on at least one of the fixed plate and the adsorption plate and is used to adjust the gap between the fixed plate and the adsorption plate.

[0014] In one embodiment, the adjustment assembly further includes an elastic element disposed on the adsorption plate for pressing the adsorption plate against the fixing plate.

[0015] In one embodiment, the adsorption mechanism further includes a sensing module disposed on the fixed plate or the adsorption plate, for sensing whether the product is present on the adsorption plate.

[0016] A testing apparatus, the testing apparatus comprising:

[0017] The adsorption mechanism as described in any of the above technical solutions.

[0018] The aforementioned adsorption mechanism and testing device place the product on the adsorption plate. Air in the adsorption channel is drawn out, creating a negative pressure between the product and the adsorption plate. This negative pressure is used to adsorb and position the product. The adsorption mechanism provided in this application, because the adsorption channel is annular and extends circumferentially along the adsorption plate, can apply negative pressure to the area surrounding the product, improving the adsorption stability of the product on the adsorption mechanism and preventing loosening or adsorption failure during the adsorption process. Furthermore, because the adsorption plate is movably mounted on the fixed plate, the relative position between the adsorption plate and the fixed plate can be adjusted to position the product adsorbed on the adsorption plate in a preset state for assembly, testing, and other operations.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0033] See Figure 1 and Figure 2 As shown, this application provides an adsorption mechanism 100, which includes a fixing plate 110 and an adsorption plate 120. The adsorption mechanism 100 is used to adsorb products, so that the products can be assembled, tested, and performed in a stable state. The products can be display modules, chips, digital products, etc., and this application does not limit the specific type of product.

[0034] The adsorption plate 120 is movably disposed on the fixed plate 110. If the adsorption plate 120 is disposed on the fixed plate 110 with a gap between it and the fixed plate 110, the adsorption plate 120 can move relative to the fixed plate 110. The adsorption plate 120 is used to adsorb products. The adsorption plate 120 has at least one adsorption air channel 121. Preferably, the adsorption air channel 121 is integrally formed on the adsorption plate 120 by injection molding, extrusion, or other methods to simplify the molding process of setting the adsorption air channel 121 on the adsorption plate 120. The adsorption air channel 121 is annular and extends along the circumferential direction of the adsorption plate 120. Preferably, the adsorption air channel 121 is disposed on the side of the adsorption plate 120 near the edge. Thus, when a product is placed on the adsorption plate 120, the air in the adsorption air channel 121 is drawn out, creating a negative pressure between the product and the adsorption plate 120. The negative pressure in the adsorption air channel 121 is used to adsorb and position the product.

[0035] The aforementioned adsorption mechanism 100, since the adsorption airway 121 is annular and extends along the circumferential direction of the adsorption plate 120, can perform negative pressure adsorption on the area surrounding the product to improve the adsorption stability of the product on the adsorption mechanism 100 and avoid undesirable phenomena such as loosening or adsorption failure during the adsorption process. Furthermore, since the adsorption plate 120 is movably mounted on the fixed plate 110, the relative positional relationship between the adsorption plate 120 and the fixed plate 110 can be adjusted to adjust the product adsorbed on the adsorption plate 120 to a preset state for assembly, testing, and other operations.

[0036] In one embodiment, see Figure 1 and Figure 2 As shown, there are multiple adsorption channels 121, which are spaced apart on the adsorption plate 120. The multiple adsorption channels 121 extend in the same direction, meaning that for two adjacent adsorption channels 121, one adsorption channel 121 is located outside the other. For example, when the product is a display module, air can be selectively drawn out from the corresponding adsorption channel 121 to create negative pressure for adsorbing products of different specifications. The adsorption plate 120 has multiple adsorption channels 121, which simultaneously adsorb the product under negative pressure. This covers the surface of the product to be adsorbed, increasing the adsorption force of the adsorption plate 120 on the product, further improving the adsorption stability of the product on the adsorption mechanism 100, and thus preventing loosening or adsorption failure during the adsorption process.

[0037] In one embodiment, see Figure 1 and Figure 2As shown, the adsorption mechanism 100 also includes a support plate 130, which is disposed on the side of the adsorption plate 120 away from the fixing plate 110. That is, the support plate 130, the adsorption plate 120, and the fixing plate 110 are stacked together, and the support plate 130 is used to support the product. The support plate 130 is provided with an annular air outlet 131 corresponding to the adsorption air channel 121. The air outlet 131 is connected to the adsorption air channel 121. Preferably, the air outlet 131 is integrally formed on the support plate 130 by injection molding, extrusion, or other methods to simplify the molding process of setting the air outlet 131 on the support plate 130. It should be noted that in this embodiment, the number of air outlets 131 is the same as the number of adsorption air channels 121. For example, if there are multiple adsorption air channels 121, there are also multiple air outlets 131, and each adsorption air channel 121 corresponds to one air outlet 131. When the product is placed on the support plate 130, the air between the adsorption plate 120, the support plate 130 and the product can be drawn out through the air outlet 131 and the adsorption air outlet 121 in sequence, so as to form a negative pressure in the gap between the adsorption plate 120, the support plate 130 and the product, and the product is adsorbed and positioned by the negative pressure.

[0038] Specifically, see Figure 1 and Figure 2 As shown, the air outlet 131 includes multiple air intake holes 1311, which are spaced apart along the circumferential direction of the support plate 130. That is, the multiple air intake holes 1311 in one air outlet 131 are arranged in a ring, and all the multiple air intake holes 1311 are connected to the adsorption airway 121. In this way, without damaging the surface shape of the support plate 130, the multiple air intake holes 1311 can guide the air between the product and the adsorption plate 120 to the adsorption airway 121, and then suck it out to the outside through the adsorption airway 121, so as to form a negative pressure in the gap between the adsorption plate 120, the support plate 130 and the product to adsorb and position the product.

[0039] Further, see Figures 1-3 As shown, the adsorption airway 121 includes a flow channel 1211, a first air intake 1212, and a second air intake 1213. Both the first air intake 1212 and the second air intake 1213 are connected to the flow channel 1211. The first air intake 1212 is located within the flow channel 1211, and the second air intake 1213 is connected to an air intake element (not shown in the figure). When the product is placed on the adsorption plate 120, due to the gap between the product and the adsorption plate 120, air from this gap flows into the adsorption airway 121. The air in the adsorption airway 121 is sequentially drawn out by the air intake element through the first air intake 1212, the flow channel 1211, and the second air intake 1213, creating a negative pressure between the product and the adsorption plate 120. This negative pressure in the adsorption airway 121 is used to adsorb and position the product.

[0040] In one embodiment, see Figure 1 and Figure 4 As shown, the adsorption mechanism 100 also includes an adjustment component 140, which connects the fixed plate 110 and the adsorption plate 120. The adjustment component 140 is used to adjust the gap between the fixed plate 110 and the adsorption plate 120. In this way, the adsorption mechanism 100 can adjust the relative position between the adsorption plate 120 and the fixed plate 110 through the adjustment component 140, so as to adjust the product adsorbed on the adsorption plate 120 to a preset state for assembly, testing and other operations.

[0041] Specifically, see Figure 1 and Figure 4 As shown, the adjustment assembly 140 includes a connector 141 and an adjusting screw 142. The connector 141 movably connects the adsorption plate 120 and the fixed plate 110, that is, the connector 141 connects the adsorption plate 120 and the fixed plate 110, and the connector 141 ensures that the adsorption plate 120 can move relative to the fixed plate 110. The adjusting screw 142 is provided on at least one of the fixed plate 110 and the adsorption plate 120, and the adjusting screw 142 is used to adjust the gap between the fixed plate 110 and the adsorption plate 120. For example, the connector 141 is an equal-height bolt, which can ensure the horizontal level of the connection between the adsorption plate 120 and the fixed plate 110. Adjusting screw 142 is screwed onto fixed plate 110, with its end abutting against the side of adsorption plate 120 near fixed plate 110. Alternatively, adjusting screw 142 is screwed onto adsorption plate 120, with its end abutting against the side of fixed plate 110 near adsorption plate 120. When adjusting the level and position of adsorption plate 120, adjusting screw 142 can be screwed onto to change its extension or retraction length, allowing it to lift adsorption plate 120 to different positions to adjust its level and position. This allows the products adsorbed on adsorption plate 120 to be adjusted to a preset state for assembly, testing, and other operations. The adjustment of adsorption plate 120 can be completed solely by adjusting screw 142, significantly saving adjustment time and improving adjustment efficiency.

[0042] Preferably, there are multiple connectors 141 and adjusting screws 142, all spaced apart along the circumferential direction of the fixing plate 110. For example, there are four connectors 141 spaced apart at the four diagonal corners of the fixing plate 110, and four adjusting screws 142 spaced apart at the four diagonal corners of the fixing plate 110. In this way, multiple connectors 141 improve the connection reliability between the adsorption plate 120 and the fixing plate 110, and multiple adjusting screws 142 allow for localized adjustment of different areas of the adsorption plate 120, preventing unevenness caused by local warping during adjustment, and even avoiding deformation of the adsorption plate 120 due to excessive warping during adjustment.

[0043] Further, see Figure 1 and Figure 4 As shown, the adjustment assembly 140 also includes an elastic element 143, which is disposed on the adsorption plate 120 and is used to press the adsorption plate 120 against the fixing plate 110. Exemplarily, in this embodiment, the elastic element 143 is a spring, which is wound around the connector 141 and located on the side of the adsorption plate 120 away from the fixing plate 110. Thus, the elastic force of the elastic element 143 can press the adsorption plate 120 against the fixing plate 110, ensuring the reliability of the connection between the adsorption plate 120 and the fixing plate 110, and preventing the adsorption plate 120 from shifting position due to external forces, thus affecting subsequent assembly, testing, and other operations of the product.

[0044] Preferably, there are multiple elastic elements 143, and the multiple elastic elements 143 correspond to multiple adjusting screws 142, that is, the position and number of elastic elements 143 correspond to the adjusting screws 142. The multiple elastic elements 143 always apply an elastic force to the adsorption plate 120, avoiding unevenness, deformation, and other defects caused by local warping during the adjustment of the adsorption plate 120. It should be noted that in other feasible embodiments, the elastic element 143 is not limited to the spring provided above, and can also be other flexible elements such as elastic sheets and elastic columns. This application does not limit the specific type of elastic element 143.

[0045] In one embodiment, see Figure 1 and Figure 2As shown, the adsorption mechanism 100 also includes a sensing module 150, which is disposed on the fixed plate 110 or the adsorption plate 120. The sensing module 150 is used to sense whether there is a product on the adsorption plate 120. For example, when the sensing module 150 senses the presence of a product on the adsorption plate 120, it draws air from the adsorption air passage 121 through the suction component to create a negative pressure between the product and the adsorption plate 120 and adsorb the product. Conversely, when the sensing module 150 senses the absence of a product on the adsorption plate 120, it does not perform the air suction operation from the adsorption air passage 121, and performs the product loading operation. The sensing module 150 can be an infrared sensor, a gravity sensor, or other sensing elements capable of acquiring product information. This application does not limit the specific type of element in the sensing module 150.

[0046] Additionally, see Figure 1 and Figure 2 As shown, this application also provides a testing device, which includes an adsorption mechanism 100 as described above. The testing device can adsorb the product onto the adsorption mechanism 100 and perform testing operations on the product.

[0047] The aforementioned testing device places the product on the adsorption plate 120. Air in the adsorption channel 121 is drawn out, creating a negative pressure between the product and the adsorption plate 120. This negative pressure in the adsorption channel 121 is used to adsorb and position the product. Since the adsorption channel 121 is annular and extends along the circumferential direction of the adsorption plate 120, it can perform negative pressure adsorption on the area surrounding the product, thereby improving the adsorption stability of the product on the adsorption mechanism 100 and preventing problems such as loosening or adsorption failure during the adsorption process. Furthermore, since the adsorption plate 120 is movably mounted on the fixed plate 110, the relative position between the adsorption plate 120 and the fixed plate 110 can be adjusted to bring the product adsorbed on the adsorption plate 120 to a preset state for testing and other operations.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
