[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0029] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] refer to Figures 1 to 5 The present application discloses a pressing device for pressing a part to a product to realize assembly of the part and the product. The product may have an inner cavity, and the part may be pressed to the cavity wall of the inner cavity of the product by the pressing device to meet the assembly requirements. For example, a part of the material may be removed from the end face of the product to form an inner cavity with an opening. Of course, the inner cavity may also be regarded as a structure such as a groove. In addition, the part may be foam, conductive cloth, etc.

[0031] The disclosed pressing device includes a jig 10 and a pressing mechanism 20. The jig 10 is used to carry the product, and the pressing mechanism 20 is used to press the part into the inner cavity of the product. Based on this configuration, during the process of the pressing mechanism 20 pressing the part into the inner cavity of the product, the bearing effect of the jig 10 on the product can help improve the stability of the product, so as to prevent the product from being squeezed and moving at will during the pressing process.

[0032] In order to achieve one-time pressing of at least two parts, in the embodiment of the present application, the pressing mechanism 20 may include at least two pressing heads, each of which has a pressing surface, and the pressing surface contacts the corresponding parts to produce an extrusion effect on the parts, thereby achieving pressing of the parts.

[0033] Optionally, the surface of each pressure head may be provided with a silicone-plated material, the hardness of which may be 50A and the thickness of which may be about 0.5 mm. Of course, other materials may also be used, which are not specifically limited here.

[0034] In the embodiment of the present application, each pressing head can be moved to facilitate pressing or disengaging parts. Among them, at least two pressing heads can move relative to each other to achieve relative folding or relative expansion, so as to enter the inner cavity of the product in a relatively folded state, or to achieve pressing of at least two parts in a relatively expanded state.

[0035] Specifically, when the pressing head enters the inner cavity of the product, at least two pressing heads can be relatively retracted to reduce the volume of the at least two pressing heads, thereby facilitating the at least two pressing heads to enter the inner cavity of the product without touching or interfering with each other; after the at least two pressing heads enter the inner cavity of the product, they can be relatively expanded, that is, at least two pressing heads move toward the cavity wall close to the inner cavity respectively, thereby producing an extrusion effect on the corresponding parts and pressing the at least two parts to the cavity wall of the inner cavity, thereby meeting the assembly requirements of the parts and products.

[0036] Therefore, in the embodiment of the present application, when at least two pressing heads are in a relatively expanded state, at least two parts can be respectively pressed to the cavity wall of the inner cavity of the product through the pressing surfaces of the at least two pressing heads to achieve assembly of the at least two parts with the product.

[0037] Compared with the method of using multiple sets of pressing devices to press multiple parts separately in the related art, the embodiment of the present application uses at least two pressing heads of the same set of pressing devices to achieve the pressing effect on at least two parts, thereby reducing the structural complexity of the device and reducing costs. In addition, it can improve the synchronization of the pressing process of at least two parts and facilitate control. At the same time, it can also achieve pressing of at least two parts at one time to improve the assembly efficiency of parts and products.

[0038] refer to Figure 3 In some embodiments, the pressing mechanism 20 may further include a driving assembly 21, which is connected to the at least two pressing heads respectively to drive the at least two pressing heads to be relatively expanded or relatively retracted. Based on this configuration, the at least two pressing heads can be driven to move by the driving assembly 21 to ensure the synchronization of the movement of the at least two pressing heads and facilitate control. In addition, it can also help to reduce the volume of the pressing mechanism 20 and reduce the occupied space.

[0039] Optionally, the driving assembly 21 may include at least two first driving modules 211, and each pressing head is correspondingly connected to the first driving module 211, so as to drive the corresponding pressing head to move through the first driving module 211, so as to make the pressing head approach or move away from the part, thereby realizing the pressing or depressing of the part.

[0040] In order to press at least two parts to different positions of the cavity wall, at least two pressing heads driven by at least two first driving modules 211 can move in different directions. Based on this, at least two parts can be pressed to different positions of the cavity wall by moving at least two pressing heads in different directions, thereby meeting the assembly requirements of at least two parts and products.

[0041] Optionally, the first driving module 211 may be a linear module, including a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0042] like Figure 3 and Figure 4 As shown, in some more specific embodiments, the at least two pressing heads may include a first pressing head 221 and a second pressing head 222, and the first pressing head 221 and the second pressing head 222 can move relative to each other to switch between a relatively retracted state and a relatively expanded state.

[0043] In the embodiment of the present application, the moving direction of the first pressing head 221 is different from the moving direction of the second pressing head 222, so as to press the first part and the second part to different positions of the cavity wall respectively. The moving direction of the first pressing head 221 and the moving direction of the second pressing head 222 can be collinear or non-collinear.

[0044] In the case of being co-linear, the first pressing head 221 can move in one direction (e.g., vertical direction, etc.), and the second pressing head 222 can also move in the direction, and the first pressing head 221 and the second pressing head 222 can be relatively close to or relatively far away from each other to achieve relative folding or relative expansion. In this case, the first part and the second part can be pressed to the relative positions of the cavity wall respectively.

[0045] In the case of non-colinearity, the first pressing head 221 can move in one direction (such as the vertical direction, etc.), and the second pressing head 222 can move in another direction (such as a direction inclined relative to the vertical direction, etc.), and the angle between one direction and the other direction is less than 180°, such as 160°, 150°, 120°, 90°, 60°, 30°, etc., which can be selected according to the assembly requirements of the parts and products. In this case, the first part and the second part can be pressed respectively to adjacent positions or spaced positions of the cavity.

[0046] In the present application embodiment, Figure 4 As shown, the side of the first pressing head 221 facing away from the second pressing head 222 can be provided with a pressing surface, that is, a first pressing surface 2211. The first pressing surface 2211 can be a plane or a curved surface, and its shape is adapted to the shape of the part to ensure that there is a sufficiently large contact area between the first pressing surface 2211 and the part, which is beneficial to improve the stability of the pressing.

[0047] Likewise, if Figure 4 As shown, the side of the second pressing head 222 facing away from the first pressing head 221 can be provided with a pressing surface, that is, a second pressing surface 2221. The second pressing surface 2221 can be a plane or a curved surface, and its shape is adapted to the shape of the part to ensure that there is a sufficiently large contact area between the second pressing surface 2221 and the part, which is beneficial to improve the stability of the pressing.

[0048] It should be noted here that the above-mentioned curved surface may include at least one curved surface unit. When it includes an integral curved surface unit, the curved surface may be an integral arc-shaped surface, a bent surface, etc.; when it includes multiple curved surface units, two adjacent curved surface units may be connected or spaced apart. In this form, the curved surface may also be an arc-shaped surface, a bent surface, etc.

[0049] To further improve the stability of the product, the fixture 10 may include a bearing component 11 and a pressing component 12. Figure 2 The bearing assembly 11 is used to bear the product, and the pressing assembly 12 is used to press the product. With the cooperation of the bearing assembly 11 and the pressing assembly 12, the stability of the product during the pressing process can be ensured, and the product can be prevented from moving randomly to affect the pressing accuracy.

[0050] The bearing assembly 11 may include a bearing platform 111 for bearing products, and the pressing assembly 12 is disposed on the bearing assembly 11 for pressing and fixing the products carried on the bearing platform 111. Based on this, the stability of the products during the pressing process can be ensured.

[0051] Optionally, the carrying platform 111 may include a bottom plate, a top plate and a plurality of support columns, wherein the plurality of support columns are respectively connected between the top plate and the bottom plate, and the surface of the top plate away from the bottom plate is the table top 1111. Based on this arrangement, on the one hand, the stability of the top plate can be improved, and on the other hand, the top plate can have a certain height to meet the bearing requirements of the product.

[0052] Continue to refer Figure 2 In some embodiments, the pressing assembly 12 may include a second driving module 121 and a pressing member 122. The second driving module 121 is connected to the carrier 111, so that the second driving module 121 can be installed and supported by the carrier 111 to ensure the stability of the second driving module 121. The second driving module 121 is also connected to the pressing member 122 to drive the pressing member 122 to move closer to or away from the table 1111 of the carrier 111 for carrying products.

[0053] Based on the above configuration, the second driving module 121 can drive the pressing member 122 to move closer to or away from the table top 1111 , so as to achieve the pressing and releasing of the product carried on the table top 1111 .

[0054] Exemplarily, the second driving module 121 may be a linear module, such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0055] The pressing member 122 may be a pressing block, a pressing plate, a pressing strip, etc. Exemplarily, the surface of the pressing member 122 in contact with the part is a pressing surface, which may be a plane or a curved surface, such as an arc surface, etc., and may be selected according to the shape of the part.

[0056] To ensure the position accuracy of the product in the second direction, the fixture 10 may further include a first positioning member 131 and a second positioning member 132. Figure 2 As shown. Among them, the first positioning member 131 and the second positioning member 132 are both arranged on the carrier 111 and protrude from the table 1111 of the carrier 111, and the first positioning member 131 and the second positioning member 132 are arranged at intervals along the second direction. Based on this arrangement, after the product is placed on the table 1111 of the carrier 111, the first positioning member 131 and the second positioning member 132 are used to position the product from both sides in the second direction to ensure the position accuracy of the product. At the same time, the first positioning member 131 and the second positioning member 132 can also limit the product in the second direction to prevent the product from moving randomly in the second direction. Therefore, the position accuracy of the product in the second direction is guaranteed.

[0057] Of course, the first positioning member 131 and the second positioning member 132 may also be relatively close to or relatively far away from each other in the second direction, so as to adapt to products with different sizes in the second direction, thereby improving the applicability of the fixture 10 .

[0058] To ensure the position accuracy of the product in the first direction, the fixture 10 may further include a third positioning member 133 and a fourth positioning member 134. Figure 2 As shown. Among them, the third positioning member 133 and the fourth positioning member 134 are both arranged on the carrier 111 and protrude from the table 1111 of the carrier 111, and the third positioning member 133 and the fourth positioning member 134 are arranged at intervals along the first direction. Based on this arrangement, after the product is placed on the table 1111 of the carrier 111, the third positioning member 133 and the fourth positioning member 134 are used to position the product from both sides in the first direction to ensure the position accuracy of the product. At the same time, the third positioning member 133 and the fourth positioning member 134 can also limit the product in the first direction to prevent the product from moving randomly in the first direction. Therefore, the position accuracy of the product in the first direction is guaranteed.

[0059] Furthermore, the fixture 10 may further include a third driving module 135, which is disposed on the carrier 111 and connected to at least one of the third positioning member 133 and the fourth positioning member 134, so that the third positioning member 133 and the fourth positioning member 134 can be relatively close to or away from each other in the first direction. Based on this arrangement, the third driving module 135 can drive at least one of the third positioning member 133 and the fourth positioning member 134 to move along the first direction, thereby meeting the positioning requirements of products with different sizes in the first direction, thereby improving the applicability of the fixture 10.

[0060] In some embodiments, the jig 10 may further include a translation mechanism 40, and the jig 10 may be disposed on the translation mechanism 40 to support the jig 10 through the translation mechanism 40 to ensure the stability of the jig 10, and may also drive the jig 10 to translate to change the position of the product carried by the jig 10, so that the pressing head can enter the inner cavity of the product to press the parts, thereby meeting the pressing requirements. Among them, the translation mechanism 40 can drive the jig 10 to move in the first direction to approach or move away from the pressing head.

[0061] Based on the above arrangement, when at least two pressing heads are in a relatively retracted state, the jig 10 and the product it carries are driven to approach the pressing heads through the translation mechanism 40, so that at least two pressing heads can extend into the inner cavity of the product; then at least two pressing heads are relatively expanded to press at least two parts onto the cavity wall of the inner cavity respectively; after the pressing is completed, at least two pressing heads are relatively retracted; then the translation mechanism 40 drives the jig 10 and the product it carries away from the pressing heads, so that at least two pressing heads can be moved out of the inner cavity of the product in preparation for the next pressing.

[0062] The translation mechanism 40 may include a base 41, a sliding assembly 42, a translation plate 43 and a fourth driving module 44. Figure 1 The fixture 10 is arranged on the translation plate 43, the sliding assembly 42 is connected between the translation plate 43 and the base 41, and the fourth driving module 44 is arranged on the base 41 and is drivingly connected to the translation plate 43. Based on this arrangement, under the driving action of the fourth driving module 44, the translation plate 43 can move smoothly and stably in the first direction relative to the base 41 through the sliding assembly 42, thereby driving the fixture 10 and the product carried by it to move in the first direction, so that the product is close to or away from the pressure head.

[0063] Optionally, the sliding assembly 42 may include a slide rail and a slider, the slide rail is provided on the base 41 or the supporting platform 111 of the fixture 10 and extends along the first direction, the slider is provided on the supporting platform 111 or the base 41 and is slidably connected to the slide rail, so that the fixture 10 can slide smoothly relative to the base 41 through the sliding cooperation between the slider and the slide rail.

[0064] Exemplarily, the slide rail may be connected to the base 41 , and the slider may be connected to the bottom plate of the carrier platform 111 .

[0065] Of course, the supporting platform 111 may be directly connected to the slide rail by sliding, and the slider may be omitted. This method can reduce the complexity of the structure and reduce the cost.

[0066] Exemplarily, the fourth driving module 44 may be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0067] refer to Figure 1 In some embodiments, the pressing device may include multiple jigs 10 and multiple pressing mechanisms 20, and the multiple pressing mechanisms 20 are respectively arranged corresponding to the multiple jigs 10. Based on this, each jig 10 can carry the product, and at least two parts can be pressed to the cavity wall of the inner cavity of the product through the corresponding pressing mechanism 20. Therefore, the assembly efficiency of parts and products can be improved by using multiple pressing mechanisms 20 and multiple jigs 10 in combination.

[0068] In some embodiments, multiple jigs 10 can be arranged on the surface of the translation plate 16 along the second direction. Based on this, under the driving action of the fourth driving mold 44, the translation plate 43 can simultaneously drive multiple jigs 10 to move synchronously in the first direction, thereby ensuring the synchronization of the movement of the products carried by the multiple jigs 10, which is conducive to improving the position accuracy of the products in the first direction.

[0069] In the embodiment of the present application, a robot arm may be used to transfer a tray for carrying products, and the tray may carry multiple products, so that the robot arm may place multiple products on the fixture 10 at one time, thereby improving the transmission efficiency of the products.

[0070] refer to Figure 1 In some embodiments, the pressing device may further include a limiting mechanism 30, by which the moving range of the fixture 10 in the first direction can be limited to prevent excessive movement.

[0071] The limiting mechanism 30 may include a first limiting member 31, such as Figure 5 As shown, the first limit member 31 and the jig 10 are spaced apart in the first direction. When the jig 10 moves toward the pressing head, the movement of the jig 10 can be limited by the first limit member 31 to prevent the jig 10 from moving excessively and causing the product to touch the pressing head.

[0072] Exemplarily, the first limiter 31 may be an electronic limiter, such as a position sensor, a proximity sensor, or the like.

[0073] like Figure 5As shown, the limiting mechanism 30 may further include a second limiting member 32, which is spaced apart from the jig 10 in the first direction. When the jig 10 moves toward the pressing head, the movement of the jig 10 may be limited by the second limiting member 32 to prevent the jig 10 from moving excessively and causing the product to touch the pressing head.

[0074] Exemplarily, the second limiting member 32 may be a mechanical limiting member, such as a limiting pin, a limiting column, or the like.

[0075] Based on the above configuration, at least one of the first limiting member 31 and the second limiting member 32 can be used to limit the jig 10 to prevent the jig 10 from excessively moving.

[0076] To sum up, the embodiment of the present application uses at least two pressing heads of the same pressing device to achieve the pressing of at least two parts, thereby reducing the structural complexity of the device, reducing costs, and improving the synchronization of the pressing process of at least two parts for easy control. At the same time, it is also possible to press at least two parts at one time to improve the assembly efficiency of parts and products.

[0077] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
