Description

Technical Field

[0001] The utility model relates to the technical field of product pressure holding and positioning, in particular to a pressure holding jig and a pressure holding device. Background Art

[0002] During the assembly of electronic products, it is usually necessary to weld two components. To ensure the welding effect, it is necessary to perform pressure holding and positioning on the two components to ensure the relative position of the two components, and thus ensure the welding quality.

[0003] In the prior art, taking a wireless Bluetooth headset as an example, the acoustic bracket of the wireless Bluetooth headset is usually small and needs to be welded. Specifically, the acoustic bracket needs to be manually assembled first and then welded. Before welding, a welding jig is first used for auxiliary pressure holding and positioning, and then welding is performed by a welding device. The welding jig usually includes a jig base and a pressing head. The jig base is provided with a product groove, and the acoustic bracket is placed in the product groove for preliminary pressure holding and positioning. The pressing head is connected to the output end of a cylinder, and the cylinder drives the pressing head to move close to the acoustic bracket to press the acoustic bracket in the product groove to prevent the acoustic bracket from moving during welding.

[0004] However, when the cylinder drives the pressing head to move and the pressing head contacts the product, it is easy to damage the product, resulting in a high rejection rate of the product and low reliability. Summary of the Utility Model

[0040] The following further elaborates on the present utility model in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model are shown in the drawings, rather than all structures.

[0041] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0042] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but are in contact through other features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the horizontal height of the first feature is lower than that of the second feature.

[0043] In the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0044] This embodiment provides a pressure-holding fixture for the pressure-holding and positioning of a product, preventing the product from being damaged by collision, and having high reliability. Exemplarily, the product can be electronic products such as headphones and acoustic brackets, or can also be other components, and this embodiment does not limit this.

[0045] As Figures 1 to 6 shown, the pressure-holding fixture includes a base 100, a flipping assembly 200 and a pressure-holding assembly 300. Among them, the flipping assembly 200 can flip relative to the base 100.

[0046] In this embodiment, the flipping assembly 200 has a first position and a second position, and the flipping assembly 200 can flip to the first position and the second position. The pressure-holding assembly 300 includes a plurality of pressure heads 310 and a plurality of first buffer members 320 corresponding to the plurality of pressure heads 310 one by one. Each pressure head 310 is slidably connected to the flipping assembly 200. Exemplarily, when the flipping assembly 200 is in the first position, the pressure head 310 is slidably connected to the flipping assembly 200 along the third direction X. When the flipping assembly 200 flips relative to the base 100, it can drive the pressure head 310 to flip relative to the base 100. Among them, the first buffer member 320 is disposed between the corresponding pressure head 310 and the flipping assembly 200, and the first buffer member 320 always has a tendency to drive the pressure head 310 to move closer to the product.

[0047] It should be noted that the third direction X can be the direction in which the indenter 310 approaches or moves away from the product. The first buffer 320 is used to provide buffering, enabling the indenter 310 to elastically contact the product, thereby avoiding hard contact between the indenter 310 and the product and reducing the probability of damaging the product. Exemplarily, the first buffer 320 can be a buffer or an elastic component. For example, the first buffer 320 can be a spring, and this embodiment does not limit this.

[0048] When the flipping assembly 200 flips to the first position, the indenter 310 contacts the product to perform pressure holding and positioning of the product; when the flipping assembly 200 flips to the second position, the indenter 310 separates from the product, such that the indenter 310 no longer performs pressure holding and positioning of the product. It should be noted that as long as the position of the flipping assembly 200 when the indenter 310 contacts the product is the first position, and as long as the position of the flipping assembly 200 when the indenter 310 separates from the product is the second position, this embodiment does not limit this. Exemplarily, Figure 1 is a schematic diagram when the flipping assembly 200 is in the first position, Figure 3 is a schematic diagram when the flipping assembly 200 is in the second position.

[0049] In the pressure holding fixture provided in this embodiment, each indenter 310 is slidably connected to the flipping assembly 200 along the third direction X, and a first buffer 320 is provided between each indenter 310 and the flipping assembly 200, such that the connection between the indenter 310 and the flipping assembly 200 is not a rigid connection. When the flipping assembly 200 flips from the second position to the first position under an external force, the downward pressure of the flipping assembly 200 is first transmitted to the first buffer 320, and after being buffered by the first buffer 320, it is then transmitted to the indenter 310. This can prevent impact damage to the product caused by too fast downward pressure or too large downward force, making the contact between the indenter 310 and the product a flexible contact, preventing hard contact between the indenter 310 and the product, and ensuring that the indenter 310 does not damage the product, having high reliability and also improving the yield of the product.

[0050] Moreover, by providing multiple indenters 310, it can contact different positions of the product, improving the pressure holding and positioning effect on the product; each indenter 310 is correspondingly provided with a first buffer 320, such that each indenter 310 can elastically abut against the product. When the surface of the product is irregular or there are manufacturing errors, due to the presence of the first buffer 320, the indenter 310 can also contact the surface of the product, further improving the pressure holding and positioning effect on the product, making the pressure holding fixture have high versatility.

[0051] Optionally, as Figure 2 and Figure 4As shown in the figure, the flipping assembly 200 includes a flipping base 210 and a sliding member 220 slidably connected to the flipping base 210 along the third direction X. Among them, the flipping base 210 is flip-connectable to the base 100, the pressing head 310 is slidably arranged along the third direction X on the sliding member 220, and the first buffer member 320 is arranged between the sliding member 220 and the pressing head 310. By providing the flipping base 210 and the sliding member 220, the sliding member 220 can move relative to the flipping base 210 in the third direction X, that is, the sliding member 220 has a space for movement in the third direction X, making the flipping assembly 200 more flexible.

[0052] In this embodiment, the pressure-holding fixture further includes a second buffer member 230. The second buffer member 230 extends along the third direction X and is arranged between the sliding member 220 and the flipping base 210. The second buffer member 230 always has a tendency to drive the sliding member 220 to move closer to the product, so as to ensure that the pressing head 310 can contact the product. The second buffer member 230 is used to provide a buffering force when the flipping assembly 200 flips to the first position, so as to prevent the flipping assembly 200 from flipping too fast and generating an impact. Moreover, the second buffer member 230 also has the function of resetting the sliding member 220. Exemplarily, the second buffer member 230 can be a buffer or an elastic member, etc. Exemplarily, the second buffer member 230 is a spring.

[0053] In some alternative embodiments, the sliding member 220 is slidably connected to the flipping base 210 through a guiding assembly 250. The guiding assembly 250 includes a guiding post arranged on one of the sliding member 220 and the flipping base 210 and a guiding hole arranged on the other. The cooperation between the guiding post and the guiding hole realizes the movable connection between the sliding member 220 and the flipping base 210 on the one hand, and can also play a guiding role in the relative movement between the two on the other hand, improving the pressure-holding positioning accuracy of the pressing head 310. Exemplarily, the second buffer member 230 is sleeved on the guiding post.

[0054] Optionally, as Figure 4 and Figure 5 shown, the flipping assembly 200 further includes a cover plate 240. One end of the cover plate 240 is rotatably connected to the sliding member 220. Exemplarily, the cover plate 240 is rotatably connected to the sliding member 220 through a rotating shaft extending along the first direction Y.

[0055] Moreover, the cover plate 240 is arranged on one side of the pressing head 310. In some alternative embodiments, when the flipping assembly 200 is in the first position, the cover plate 240 is located on one side of the pressing head 310 in the second direction Z. In Figure 5In this case, the cover plate 240 is located on top of the press head 310. The cover plate 240 can be rotated relative to the slider 220 to a third position and a fourth position. When the cover plate 240 is rotated to the third position, the flipping assembly 200 flips to the first position, and the cover plate 240 contacts the press head 310 to prevent the press head 310 from rotating. It should be noted that the cover plate 240 can press on the press head 310 by its own gravity to prevent the press head 310 from moving. When the cover plate 240 is rotated to the fourth position, the cover plate 240 is separated from the press head 310. The setting of the cover plate 240 enables the press head 310 to stably contact the product, improves the stability of pressure holding and positioning of the product, and avoids the separation of the press head 310 from the product caused by the compression of the first buffer member 320 due to the shaking of the pressure holding fixture. It should be noted that as Figure 1 shown, the second direction Z is perpendicular to the first direction Y, and the second direction Z can be the thickness direction of the base 100.

[0056] Further optionally, as Figure 3 shown, the pressure holding fixture further includes a locking mechanism 700. Among them, the locking mechanism 700 is movably connected to the slider 220. When the flipping assembly 200 flips to the first position, the locking mechanism 700 can lock the slider 220 to the base 100, so that the flipping assembly 200 can be kept in the first position and the cover plate 240 can be kept in the third position. By setting the locking mechanism 700, on the one hand, it can ensure that the flipping assembly 200 is kept in the first position and ensure that the position of the press head 310 can contact the product. On the other hand, the setting of the locking mechanism 700 can also overcome the buffering force of the second buffer member 230 on the slider 220, prevent the slider 220 from shaking, and improve the accuracy of pressure holding.

[0057] In this embodiment, the locking mechanism 700 is movably arranged on the cover plate 240. When the cover plate 240 is in the third position, the locking mechanism 700 locks the cover plate 240 on the base 100, so that the flipping assembly 200 flips to the first position, enabling the cover plate 240 to be kept in the third position and also improving the limiting effect of the cover plate 240 on the press head 310.

[0058] Further optionally, as Figure 4 shown, the locking mechanism 700 includes a locking member 710, an elastic member 720 and a locking shaft 730. The locking member 710 is rotatably connected to the cover plate 240 through the locking shaft 730. A hook portion 711 is provided at the bottom of the locking member 710, and the hook portion 711 can abut against the surface of the base 100 facing away from the cover plate 240. The elastic member 720 is arranged between the top of the locking member 710 and the cover plate 240, and the elastic member 720 always has a tendency to drive the top of the locking member 710 to move away from the cover plate 240, so that the hook portion 711 at the bottom of the locking member 710 can be kept hooked on the base 100, thereby realizing locking.

[0059] In some alternative embodiments, such as Figure 4 As shown, the middle part of the flipping base 210 is connected to the base 100 through a flipping shaft 400, and the flipping base 210 can be rotatably connected to the base 100 through the flipping shaft 400. The position where the flipping base 210 is rotatably connected to the base 100 is located in the middle part of the flipping base 210, which can reduce the torque when the flipping base 210 flips and facilitate the flipping of the flipping assembly 200. In some alternative embodiments, the middle part of the flipping base 210 in the third direction X is connected to the base 100 through a flipping shaft 400.

[0060] Exemplarily, such as Figure 4 As shown, the flipping base 210 is provided with a through hole 211, and the flipping shaft 400 passes through the through hole 211 and is connected to the base 100, so that the flipping base 210 flips relative to the base 100 through the flipping shaft 400.

[0061] Optionally, such as Figure 6 As shown, the pressing head 310 includes a connected connecting part 311 and a pressing part 312. Among them, the connecting part 311 and the pressing part 312 are arranged at an obtuse angle, and a first buffer 320 is provided between the connecting part 311 and the flipping assembly 200. When the flipping assembly 200 flips to the first position, the pressing part 312 contacts the product, and when the flipping assembly 200 flips to the second position, the pressing part 312 is separated from the product. By setting the connecting part 311 to be arranged at an obtuse angle with the pressing part 312, the pressing head 310 can undergo a small amount of deformation. For example, when the pressing part 312 contacts the product, the pressing part 312 can move relative to the connecting part 311 within a certain range to increase the included angle between the two, preventing the pressing part 312 from damaging the product. It should be noted that the pressing head 310 can still maintain pressure and position the product after undergoing a small amount of deformation.

[0062] Further optionally, please continue to refer to Figure 4 , the pressing part 312 includes a pressing main body and a pressing end 3121. One end of the pressing main body is connected to the connecting part 311, the pressing end 3121 is connected to the other end of the pressing main body, the cross-sectional area of the pressing main body is smaller than that of the connecting part 311 and smaller than that of the pressing end 3121. By designing the cross-sectional area of the connecting part 311 to be larger, the connection strength between the connecting part 311 and the sliding part 220 can be improved. By designing the cross-sectional area of the pressing end 3121 to be larger, the contact area between the pressing end 3121 and the product is larger, thereby ensuring the reliability of pressure maintaining and positioning. By setting the pressing main body to be thinner, on the one hand, the weight of the pressing head 310 can be reduced, and on the other hand, the shielding of the pressing main body from the welding equipment can be reduced, ensuring the welding quality.

[0063] In some alternative embodiments, a plurality of punches 310 are arranged at intervals in the first direction Y, such that the plurality of punches 310 can contact different positions of the product in the first direction Y, thereby improving the uniformity of pressure holding and positioning.

[0064] Optionally, as Figure 6 shown, the pressure holding fixture further includes at least one slide rail 500 and a plurality of sliders 600. Among them, the plurality of sliders 600 are connected to the plurality of punches 310 in a one-to-one correspondence. The slide rail 500 is connected to the flipping assembly 200. In some alternative embodiments, when the flipping assembly 200 is in the first position, the slide rail 500 extends in the third direction X. In this embodiment, two adjacent sliders 600 in the first direction Y are slidably arranged on the same slide rail 500, that is, two sliders 600 can share one slide rail 500. On the one hand, the utilization rate of the slide rail 500 is improved, and on the other hand, the number of components of the pressure holding fixture can be reduced, which is beneficial to the lightweight of the pressure holding fixture. The space occupied by the slide rail 500 and the sliders 600 is small, which is beneficial to the miniaturization of the pressure holding fixture.

[0065] Exemplarily, in this embodiment, there is one slide rail 500, two sliders 600 and two punches 310 are provided. The two sliders 600 are slidably arranged on both sides of the slide rail 500. For example, in this embodiment, the slider 600 is a dovetail groove slider and the slide rail 500 is a dovetail groove slide rail.

[0066] As Figure 3 shown, the base 100 is provided with a limiting support member 110. The limiting support member 110 is used to contact the flipping assembly 200 and support the flipping assembly 200 when the flipping assembly 200 is flipped to the first position, so as to improve the stability of the flipping assembly 200 when it is in the first position and reduce the probability of affecting the pressure holding and positioning effect due to the shaking of the flipping assembly 200. Exemplarily, the flipping seat 210 can contact the limiting support member 110.

[0067] This embodiment also provides a pressure holding device, which has a good pressure holding and positioning effect and pressure holding and positioning reliability.

[0068] As Figure 7 and Figure 8 shown, the pressure holding device includes a carrier 10 and the above-mentioned pressure holding fixture, and the pressure holding fixture is installed on the carrier 10.

[0069] Exemplarily, as Figure 7 shown, the carrier 10 is provided with a profiling groove 101. The profiling groove 101 is used to accommodate the product, and one end of the punch 310 can extend into the profiling groove 101 to cooperate with the profiling groove 101 to perform all-round pressure holding and positioning of the product.

[0070] Optionally, in either the carrier 10 or the base 100, one is provided with a positioning hole 102, and the other is provided with a positioning pin 120. The positioning pin 120 can be inserted into the positioning hole 102 to achieve the pressure-holding positioning of the carrier 10 and the base 100. A plurality of positioning pins 120 and positioning holes 102 can be provided in one-to-one correspondence to improve the pressure-holding positioning effect.

[0071] Alternatively, both the carrier 10 and the base 100 can be provided with magnetic members. The carrier 10 and the base 100 are magnetically connected by the adsorption of the magnetic members, reducing the probability of the base 100 moving relative to the carrier 10.

[0072] When using the pressure-holding device provided in this embodiment, the carrier 10 and the pressure-holding jig are in the separated state as shown in Figure 8 Figure. First, place the product into the profiling groove 101. Then, align the positioning pin 120 and the positioning hole 102 on the carrier 10 and the base 100. If magnetic members are provided, align the magnetic members on both of them at the same time. Control the pressure-holding jig to move closer to the carrier 10 to install the pressure-holding jig on the carrier 10. It should be noted that during the process of installing the pressure-holding jig on the carrier 10, the flipping assembly 200 is always in the second position so as not to damage the product. And the locking mechanism 700 is in the unlocked state. After that, control the flipping assembly 200 to move from the second position to the first position until the flipping assembly 200 is located at the first position. At this time, the pressing end 3121 of the pressing head 310 contacts the product to limit the product in the profiling groove 101. Then, fasten the cover plate 240 so that the connecting portion 311 of the cover plate 240 contacts the pressing head 310, and operate the locking mechanism 700 to lock the cover plate 240 on the base 100. The settings of the first buffer member 320 and the second buffer member 230 ensure that the pressing head 310 does not damage the product, guaranteeing the yield rate of the product. After the pressure-holding positioning is completed, the product is welded using a welding device.

[0073] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
