Description

Technical Field

[0001] This application relates to the technical field of electronic equipment, and specifically proposes a pressure holding device for a workpiece and a pressure gauge thereof. Background Technology

[0002] Currently, in the production of some electronic devices, certain components require pressure holding. For example, the external decorative parts of an electronic pen require heat-sensitive films to be hot-melt bonded to opposite sides of their perimeter and then subjected to pressure holding.

[0003] However, traditional pressure-holding devices consist of a support and a pressure head. The support is a rigid structure that only provides support, while the pressure head is a flexible structure that provides pressure holding. During pressure holding, the electronic pen decorative piece is positioned between the support and the pressure head. Furthermore, a thermal film is only applied to the side of the decorative piece facing the pressure head for single-sided heat fusion pressure holding. After completion, the decorative piece is rotated so that the other side faces the pressure head, and another thermal film is applied for heat fusion pressure holding. This means that single-sided pressure holding is performed twice, resulting in low production efficiency. In addition, during the pressure holding process, the support cannot adaptively absorb the volume shrinkage of the melt during cooling; relying solely on the flexible pressure head for pressure holding leads to poor pressure holding performance.

[0032] It should be understood that the terms "comprising," "including," and "having" are open-ended, indicating the presence of the stated features but not excluding the possibility of other features in the embodiment. Similarly, the use of terms such as "first," "second," etc., to describe multiple features only indicates the distinction between one feature and another, and such terms do not imply order or sequence unless explicitly stated in the context.

[0033] It should be understood that, unless the context clearly indicates otherwise, the terms "setup," "connection," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integrated connection; they can refer to a direct connection or an indirect connection via a medium. Those skilled in the art will understand the specific meaning of these terms in this document based on the specific circumstances.

[0034] In addition, for ease of description, the text will use terms of spatial relative relationship to describe the position of one feature relative to another feature, such as "inner", "outer", "end", "side", "upper", "middle", "lower", "high", "low", "axial", "circumferential", "radial", "horizontal", "vertical", "first direction", "second direction", etc. It can be understood that the spatial relative relationship between two features should include other specific situations besides those shown in the accompanying drawings of the specification.

[0035] The embodiments of this application are described below with reference to the accompanying drawings. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as they do not conflict with each other.

[0036] In a first aspect, embodiments of this application provide a pressure-holding device for a workpiece, comprising a first module 110 and a second module 120. The first module 110 includes a first base 111 and a first pressure head 112 disposed on the first base 111; the second module 120 includes a second base 121 and a second pressure head 122 disposed on the second base 121, the second base 121 being spaced apart from the first base 111, the second pressure head 122 being distributed opposite to the first pressure head 112, and a workpiece pressure-holding space being formed between the second pressure head 122 and the first pressure head 112; wherein both the first pressure head 112 and the second pressure head 122 are soft structures.

[0037] In this embodiment, refer to Figures 1 to 7 Key reference Figure 3 The first module 110 includes a first pressure head 112, and the second module 120 includes a second pressure head 122. The first pressure head 112 and the second pressure head 122 are arranged opposite to each other, forming a pressure-holding space between them. Specifically, both the first pressure head 112 and the second pressure head 122 are flexible structures. The part 30 is placed between the first pressure head 112 and the second pressure head 122. Thermosensitive adhesive sheets 40 can be provided on both sides of the part 30 facing the first pressure head 112 and the second pressure head 122, so that the first pressure head 112 and the second pressure head 122 press against the part 30, ensuring that the thermosensitive adhesive sheets 40 on both sides are adhered to the part 30 after being heated and melted, and that the subsequent pressure-holding process can be completed. This application can complete the connection and pressure holding of the thermosensitive adhesive sheets 40 on both sides of the part 30 in one operation, resulting in high production efficiency. Moreover, since both the first pressure head 112 and the second pressure head 122 are flexible structures, they can both play a pressure-holding role, resulting in good pressure-holding effect.

[0038] It should be noted that the surfaces of the first pressure head 112 and the second pressure head 122 that contact the workpiece 30 are respectively adapted to the workpiece 30. In production, the first thermal film 40 can be placed on the second pressure head 122 first, then the workpiece 30 can be placed, followed by the second thermal film 40 on the workpiece 30. Then, the second module 120 can be brought close to the first module 110 so that the first pressure head 112 presses against the workpiece 30 (or the second thermal film 40) and provides external force to the first module 110 to prevent it from moving away from the second module 120 (for example, by the locking member 123 described below). The workpiece pressure holding device is placed in an oven or other equipment for heating, and the thermal film 40 will melt and adhere to the workpiece 30. In subsequent processes, the first pressure head 112 and the second pressure head 122 always apply pressure to the two thermal films 40 to enhance their connection with the workpiece 30.

[0039] To further explain, the pressure holding function is used to compensate for the volume shrinkage of the melt during cooling, preventing defects such as shrinkage marks and dents from appearing in the product. Both the first pressure head 112 and the second pressure head 122 are soft structures, and both can play a role in pressure holding.

[0040] In some embodiments, the pressure holding device for the workpiece further includes a first elastic element 113, a first pressure head 112 connected to a first base 111 via the first elastic element 113, and / or a second pressure head 122 connected to a second base 121 via the first elastic element 113.

[0041] In this embodiment, refer to Figure 3 The first pressure head 112 is connected to the first base 111 through the first elastic element 113. During the pressure holding process, the first elastic element 113 always keeps the first pressure head 112 pressed against the heat-sensitive film 40 and the part 30, thereby further increasing the deformation range of the first pressure head 112 and enhancing the pressure holding effect. Moreover, the first elastic element 113 can also absorb the manufacturing tolerance of the part 30 itself, providing versatility.

[0042] Of course, in some embodiments not shown in the figures, the second pressure head 122 may also be connected to the second base 121 via the first elastic member 113.

[0043] In some embodiments, the pressure holding device for the workpiece further includes a locking member 123, which locks the first base 111 and the second base 121.

[0044] In this embodiment, refer to Figure 2 and Figure 3The locking element 123 limits the first base 111 and the second base 121, preventing them from moving away during the pressure holding process and affecting the production results; moreover, this solution has a simple structure and a good locking effect. It is understood that in some embodiments not shown in the figure, a continuous external force can also be used as the locking force, for example, a hydraulic cylinder can be used to apply force to the first base 111, which is also a desirable embodiment.

[0045] In some embodiments, one of the first base 111 and the second base 121 is provided with a hinge frame 124, and a locking member 123 is hinged to the hinge frame 124; the locking member 123 has a first end and a second end opposite to each other, the first end is provided with a hook 1231, the hook 1231 is engaged with the other of the first base 111 and the second base 121, and a second elastic member 125 is provided between the second end and the hinge frame 124.

[0046] In this embodiment, a specific implementation of the locking member 123 is proposed, with particular reference to... Figure 8 The middle part of the locking member 123 is hinged to the second base 121 via the hinge frame 124. One end of the locking member 123 is engaged with the first base 111 by the hook 1231, and the other end is provided with a second elastic member 125 between the locking member 123 and the hinge frame 124. The second elastic member 125 has an elastic force that makes the locking member 123 move away from the hinge frame 124, thereby making the hook 1231 further engage the first base 111 under the leverage effect.

[0047] In some embodiments, one of the first base 111 and the second base 121 is provided with a sleeve 126, and the other is provided with a guide rod 114, which passes through the sleeve 126; a third elastic element 115 is provided on the guide rod 114, which abuts against the first base 111 and the second base 121.

[0048] In this embodiment, refer to Figure 3 The guide rod 114 cooperates with the sleeve 126 to facilitate positioning and prevent horizontal swaying and misalignment between the first base 111 and the second base 121. Furthermore, the first base 111 and the second base 121 are provided with a third elastic element 115. After the locking element 123 is unlocked, the third elastic element 115 facilitates the separation of the first base 111 and the second base 121, making operation convenient.

[0049] Optionally, the first elastic element 113, the second elastic element 125 and the third elastic element 115 are springs, wherein the third elastic element 115 is sleeved on the guide rod 114.

[0050] In some embodiments, the first base 111 includes a first plate 1111 and a first seat 1112 connected together. The first seat 1112 is provided with a first limiting groove 1113. The first pressing head 112 is at least partially accommodated in the first limiting groove 1113 and is connected to the first plate 1111. And / or, the second base 121 includes a second plate 1211 and a second seat 1212 connected together. The second seat 1212 is provided with a second limiting groove 1213. The second pressing head 122 is at least partially accommodated in the second limiting groove 1213 and is connected to the second plate 1211.

[0051] Reference Figures 3 to 5 The first seat 1112 uses the first limiting groove 1113 to limit the first pressure head 112, and the second seat 1212 uses the second limiting groove 1213 to limit the second pressure head 122, so as to ensure the structural stability of the first pressure head 112 and the second pressure head 122, avoid horizontal shaking or large deformation, and ensure the pressure holding effect.

[0052] In some embodiments, the first pressure head 112 and / or the second pressure head 122 are provided with a positioning rod 127, which is located within the pressure holding space of the workpiece.

[0053] Reference Figure 3 and Figure 7 The positioning rod 127 is connected to the second pressure head 122. The part 30 and the thermal film 40 are provided with assembly holes 301 (the product itself needs to be opened). The positioning rod 127 passes through the assembly hole 301 and abuts against the first pressure head 112, thereby realizing the positioning of the part 30 and the thermal film 40, avoiding misalignment, and ensuring the finished product effect.

[0054] In some embodiments, the first module 110 includes a plurality of first pressure heads 112, and the second module 120 includes a plurality of second pressure heads 122, wherein the plurality of first pressure heads 112 and the plurality of second pressure heads 122 are configured in a one-to-one correspondence.

[0055] Reference Figures 3 to 5 The first module 110 is equipped with multiple first pressure heads 112, and the second module 120 is equipped with multiple second pressure heads 122, which enables pressure holding of multiple parts 30 at one time, thereby improving production efficiency.

[0056] In some embodiments, one of the first base 111 and the second base 121 is provided with a support column 1214, and the other is provided with a positioning groove 1114; the first module 110 and the second module 120 form a pressure holding assembly 10, and the workpiece pressure holding device includes a plurality of pressure holding assemblies 10, which are stacked and arranged by the cooperation of the support column 1214 and the positioning groove 1114.

[0057] Reference Figure 1Multiple pressure-holding components 10 are stacked, and each pressure-holding component 10 can hold pressure on multiple parts 30, thereby further improving production efficiency. In addition, the cooperation between the support column 1214 and the positioning groove 1114 ensures the firmness of the stack, and the structure is simple and easy to operate.

[0058] Secondly, embodiments of this application provide a pressure gauge for a part-holding pressure device, used to detect the pressure of the first module 110 or the second module 120 on the part 30 in the part-holding pressure device of the first aspect. It includes a third base 210, a pressure sensor 220 and a simulation element 230. The simulation element 230 is disposed on the third base 210, and the pressure sensor 220 is at least partially disposed between the simulation element 230 and the third base 210. The third base 210 is spaced apart from the first base 111, and the simulation element 230 abuts against the first pressure head 112; or, the third base 210 is spaced apart from the second base 121, and the simulation element 230 abuts against the second pressure head 122.

[0059] Reference Figure 9 In this embodiment, the third base 210 is provided with a locking member 123, a hinge frame 124, a sleeve 126, and other structures, meaning that the third base 210 can cooperate with the first base 111. The simulation member 230 is equivalent to the shape of the second pressure head 122 and the workpiece 30 after being stacked. After the first base 111 approaches the third base 210 and locks, the first pressure head 112 presses against the simulation member 230. The simulation member 230 has a receiving groove inside, and a pressure sensor 220 is provided in the receiving groove, so that the pressure applied by the first pressure head 112 can be detected to ensure the pressure holding effect of the workpiece pressure holding device.

[0060] Specifically, refer to Figure 9 The third base 210 is provided with a groove 211, which limits the position of the pressure sensor 220. Magnets 250 are provided on both the groove 211 and the pressure sensor 220 for magnetic attraction and fixation. In addition, the third base 210 is provided with a positioning post 240, and the simulation component 230 is provided with a positioning hole. The positioning post 240 passes through the positioning hole to achieve the positioning effect of the simulation component 230. The simulation component 230 can also be magnetically connected to the third base 210 using the magnets 250.

[0061] It should be understood that, in some embodiments not shown in the figures, the pressure gauge of the workpiece pressure holding device may also cooperate with the second base 121 to detect the pressure of the second pressure head 122.

[0062] Optionally, part 30 is a decorative part for the electronic pen.
